Letter to Shareholders

Dear Shareholders,

At Millicom (Tigo) our customers come first. As we look back on 2024 we stay focused on delivering great service and smart solutions that support the communities we serve.

Looking ahead to 2025, we’re entering a time of big change. New technologies like generative AI and supercomputing are changing how people connect, communicate, and innovate. The digital world is moving fast, and the need for high-speed data is driving it all.

Millicom (Tigo) is well positioned to seize the opportunities this new era presents. Our robust fixed and mobile networks, comprehensive digital platforms, and diverse content offerings—including cable, entertainment, and cloud solutions—equip us to meet the growing demand for connectivity and digital services.

At the heart of this success is the strength of the Tigo brand, a trusted name in Latin America synonymous with quality, innovation, and social impact. Our continued investment in the brand ensures that we remain relevant and deeply connected to the communities we serve—both emotionally and technologically.

Our strong financial foundation and strategic scale enable us to drive growth and deliver exceptional value to our customers and stakeholders in this rapidly evolving digital landscape. This strong financial position is the result of a transformative 2024, during which we successfully completed our restructuring program. This initiative significantly strengthened the company’s financial health, allowing us to focus more intently on our core purpose: building digital highways, connecting people, and developing our communities.

Financially, 2024 was a standout year for Millicom, as Operating Profit grew by 62.5% to $1.34 billion, and Net Income attributable to owners of the Company reached $253 million ($1.47 per share), a substantial improvement from a net loss of $82 million in 2023. Net Cash Provided by Operating Activities totaled $1.60 billion, driving Equity Free Cash Flow(1) to a record of $777 million. This robust cash generation enabled us to reduce debt, bringing our leverage down within our stated target range.

Our restructuring journey began with Project Everest in 2022. Throughout 2023, with strong support from Atlas, we expanded the project's scope, laying the groundwork for our solid performance in 2024. Key achievements of the restructuring program include:

•Employee-Related Cost Reductions: Achieved approximately 15% savings, excluding restructuring costs, through a 27% average headcount reduction across all geographies and functions over the past two years.

•Operational Expense Savings: Reduced 2024 spending by approximately 21% on programming, 18% on information technology, and 18% on external services, by renegotiating and re-scoping supplier contracts.

•Enhanced Capital Efficiency: Lowered capital investment by 30% over the past two years while reducing churn and increasing average speeds delivered to our residential broadband customers.

These strategic actions have resulted in a more efficient company with a reduced baseline for operating and capital expenditures. This relentless focus on efficiency has become ingrained in our corporate culture. Consequently, the Board has decided to reinstate shareholder remuneration, which had been on pause since the pandemic.

Millicom achieved significant milestones across several strategic initiatives:

Colombia

•Tower Sale and Network Collaboration: We completed the sale of our Colombian tower assets to KKR and entered into a joint operation with Telefónica to establish a unified mobile access network. This collaboration includes sharing radioelectric spectrum usage permits, enhancing network efficiency and coverage across the country.

•Acquisition of Telefonica's Stake in Coltel: Millicom signed a definitive agreement to acquire Telefónica's controlling 67.5% equity interest in Telefónica Colombia, or Telecomunicaciones S.A. ESP BIC ("Coltel"). We also plan to offer to purchase the remaining 32.5% stake from La Nación and other shareholders. This strategic move aims to create a robust telecom entity with the scale and financial capacity to support significant network and spectrum investments, aligning with Colombia's digital inclusion objectives.

Central America

•Tower Portfolio Sale and Leaseback: We agreed with SBA Telecommunications LLC to sell and lease back our portfolio of more than 7,000 towers in Central America. The transactions will allow Millicom to exit the non-core tower business and to re-deploy capital in the Company's core connectivity business.

Costa Rica

•Operational Merger with Liberty Latin America: In Costa Rica, we signed a binding agreement with Liberty Latin America to combine our operations to increase scale. The combined entity will be in a position to accelerate the deployment of FTTH and 5G networks in the country.

Corporate Governance

1. Delisting from Nasdaq Stockholm: We delisted our Swedish Depository Receipts from Nasdaq Stockholm, in order to improve overall liquidity, attract new investors focused on Latin America, simplify corporate governance, and reduce administrative costs.

2. As part of our transformation, we have also significantly streamlined our corporate headquarters in Miami, empowering our country operations with more autonomy and decision-making authority. This leaner central structure allows us to be more agile, responsive, and aligned with local market needs—amplifying the impact of our strategy where it matters most.

These strategic actions reflect our commitment to strengthening our core operations, enhancing financial flexibility, and positioning Millicom for sustainable growth in the evolving digital landscape.

Thank You

Today, Millicom Tigo is a more focused and agile company, dedicated to meeting the evolving needs of our customers across Latin America. We are proud to deliver consistent financial performance while expanding digital access and inclusion in the communities we serve.

· To our customers: Thank you for choosing and staying with Tigo. You are the reason we innovate, grow, and invest in the future of digital connectivity. We are honored by your trust, and we will continue to prioritize your needs as we connect more people and communities to opportunities every day.

· To our shareholders: Thank you for your trust and confidence in Millicom. We entered 2025 with stronger fundamentals, a sharper strategic focus, and a clear path to long-term value creation. We remain committed to disciplined execution and enhancing your returns as we continue building a digital future for all.

· To our employees: Thank you for your unwavering commitment to our customers and your contribution to moving our business forward. Your energy and belief in our purpose bring vibrancy to our culture and drive continuous innovation and impact.

As we begin our second year in our respective roles, we have established a clear strategy, refined our operating model, and set ambitious targets. Our focus now is on execution—delivering on our commitments to our customers, employees, investors, and the communities we serve.

PRESENTATION OF FINANCIAL AND OTHER INFORMATION

Financial statement information

We have included in this Annual Report the Millicom Group’s (as defined below) audited consolidated financial statements as of December 31, 2024 and 2023 and for the years ended December 31, 2024, 2023 and 2022. The Millicom Group’s audited consolidated financial statements included herein and the accompanying notes thereto have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”). We end our fiscal year on December 31. References to fiscal 2024, fiscal 2023 and fiscal 2022 refer to the years ended December 31, 2024, 2023 and 2022, respectively.

Our management determines operating and reportable segments based on the reports that are used by the chief operating decision maker (the "CODM") to make strategic and operational decisions from both a business and geographic perspective. Our risks and rates of return for our operations were predominantly affected by operating in different geographical regions. During the latter half of 2023, Millicom implemented significant organizational changes to focus on driving profitable growth with a leaner corporate structure. The Group also adopted a decentralized approach to streamline decision-making processes and enhance agility to improve profitability and shareholder value. Following these organizational changes, and considering the information being reviewed by the CODM to assess performance and allocate resources, Millicom's operating segments were redefined to align with its countries of operation. Our reportable segments consist of Guatemala, Colombia, Panama, Bolivia, Honduras, Paraguay and Other, which includes Nicaragua, Costa Rica and El Salvador. See “Operating and Financial Review and Prospects—Operating Results—Our segments.”

Presentation of data

We present operational and financial data in this Annual Report. Operational data, such as the number of customers, unless otherwise indicated, are presented for the Millicom Group at a consolidated level, and exclude our Honduras joint venture.

Financial data is presented either at a consolidated level or at a segmental level, as derived from our consolidated financial statements, including the notes thereto. At a consolidated level, we account for our operations in Honduras as a joint venture using the equity method of accounting. At a segmental level, we account for our operations in Honduras as if they were fully consolidated, as this reflects the way management views and uses internally reported information to make decisions.

We have made rounding adjustments to reach some of the figures included in this Annual Report. Accordingly, figures shown as totals in some tables may not be an exact arithmetic aggregation of the figures that preceded them, and percentage calculations using these adjusted figures may not result in the same percentage values as are shown in this Annual Report.

Certain references

Unless the context otherwise requires, references to the “Company” or “MIC S.A.” refer only to Millicom International Cellular S.A., a public limited liability company (société anonyme) organized and established under the laws of the Grand Duchy of Luxembourg, and the terms “Millicom,” “Millicom Group,” “our Group,” “we,” “us” and “our” refer to Millicom International Cellular S.A. and its consolidated subsidiaries and, where applicable, our joint venture in Honduras.

Additionally, the risk factors described in this section have been separated into four separate but interrelated areas:

1.risks related to the telecommunications, cable and MFS industries;

2.risks related to Millicom’s business in the markets in which it operates;

3.risks related to Millicom’s size, structure and leadership; and

4.risks related to share ownership, governance practices, and registration with the Securities and Exchange Commission ("SEC").

1.Risks related to the telecommunications, cable and MFS industries

a.Evolution of the telecommunications, cable and MFS industries

The telecommunications industry is characterized by rapid technological change and continually evolving industry standards.

The telecommunications industry is characterized by rapidly changing technology and evolving industry standards. The technology we use is increasingly complex, which leads to higher risks of implementation failure or service disruption. Success in the industry is increasingly dependent on the ability of operators to adapt to the changing technological landscape. The technologies utilized today may become obsolete or subject to competition from new technologies in the future. For example, our hybrid fiber-coaxial ("HFC") services may become obsolete once faster and more affordable fiber-to-the-home ("FTTH") services are available for consumers.

Growth in internet connectivity has led to the proliferation of entrants offering Voice over Internet Protocol (“VoIP”) services, video content services, and messaging services delivered over the internet. Such operators could displace the services we provide by using our customers’ internet access (which may or may not be provided by us) to enable the provision of communication, entertainment and information services directly to our customers. Failure to transform to data-driven products could have a negative impact on our legacy services and impact our results from operations.

Our ability to attract and retain customers is, in part, dependent on our ability to meet customer demand for new technology at the same, or at a quicker rate, than our competitors are able to do.

Failure to adapt and evolve could harm our competitive position, render our products obsolete and cause us to incur substantial costs to replace our products or implement new technologies.

Implementing new technologies requires substantial investments which may not generate expected returns.

The introduction of new technologies may require significant capital expenditure on infrastructure, and there can be no guarantee that those investments will generate expected returns. For example, penetration rates for fixed broadband services in our markets are low relative to penetration rates in other markets globally. As the use of these services has the potential to increase substantially over time, we have expended significant resources to deploy both HFC and FTTH networks in several of our markets. However, an increasing number of local and regional providers of fiber connections are offering internet services with the same or higher data speeds at competitive prices, and competition for dedicated fiber optic services is intense. While we continue to expand these networks with the intention of capturing the anticipated demand, future offerings by our competitors that are aggressively priced or that offer additional services may prevent us from achieving the expected returns on this investment. If we are required to implement new technologies that are unable to generate sufficient returns, our profitability and ability to generate cash flow would be negatively affected, and we may be required to scale back our investments or delay the implementation of new technologies, which may have a negative impact on our growth and ability to attract and retain customers.

In addition, if competitive or other factors compel the need to invest in new technologies earlier than anticipated, previous equipment or technology may need to be impaired or written-down if replaced earlier than originally anticipated.

If we cannot successfully develop and operate our mobile, cable and broadband networks, MFS and distribution systems, we will be unable to expand our customer base and may lose market share and revenue.

Our ability to increase or maintain our market share and revenue is partly dependent on the success of our efforts to expand our business, the quality of our services and the management of our networks and distribution systems. As new technologies are developed or upgraded, such as advanced 5G systems and fiber optic cable networks, our equipment may need to be replaced or upgraded or we may need to rebuild our mobile, cable or broadband network, in whole or in part. In some cases, the COVID-19 pandemic accelerated the transition from traditional to digital services, including MFS, and the heightened customer expectations in these areas may require us to invest greater resources in technological improvements.

The initial build-out of our networks and distribution systems, together with sustaining sufficient network performance and reliability, is a capital-intensive process that is subject to risks and uncertainties which may delay the introduction of services and increase the cost of network construction or upgrade. With regard to our strategic efforts in broadband services, we seek to increase our market share in both the residential and commercial broadband markets by investing significant resources in HFC and FTTH networks, in addition to fixed broadband services through wireless communication networks, known as fixed wireless access ("FWA"). The provision of broadband services is highly capital intensive, and the long-term nature of the return on investment increases the risks to our operations. Potential difficulties include constraints on our ability to fund additional capital expenditures, as well as external forces, such as obtaining necessary permits from regulatory and other local authorities.

Unforeseeable technological developments may also render our services or distribution channels unpopular with customers or obsolete. To the extent we fail to expand, upgrade and modernize our networks and distribution systems on a timely basis relative to our competitors, we may not be able to expand our customer base and we may lose customers to competitors. If any of these risks materialize, we may be at a competitive disadvantage, which could result in the loss of customers or the inability to attract new customers and maintain or grow our market share. In turn, this would impact our revenue and profitability and our ability to generate cash to grow or sustain our businesses.

b.Content and content rights

Content and programming costs are rising (especially those with exclusivity rights), and we may not be able to pass the increased costs on to our customers.

In recent years, the cable TV and direct-to-home satellite TV industries (together “pay-TV”) have experienced a rapid escalation in the cost of content rights and programming. We expect these costs may continue to increase, particularly those related to exclusive and live broadcasts of sporting and other events. As of December 31, 2024, we had exclusivity rights over certain local soccer content in several of our markets, including Bolivia, Costa Rica, El Salvador, Guatemala, Honduras, Panama and Paraguay, and we expect that the costs of these rights may continue to increase significantly. If we are unable to moderate the growth in these costs or fully pass them on to our customers in the form of price increases, we may lose our rights to

this content. Any failure to maintain such rights may reduce the desirability of our networks and negatively affect our profitability.

In addition, content is often priced in U.S. dollars, which may result in fluctuations in costs in the countries in which we sell content due to foreign exchange fluctuations.

We make long-term content and service commitments in advance even though we cannot predict the popularity of the services or ratings the programming will generate, and our mobile applications and cable content may not be accepted or widely used by our customers.

We acquire rights to distribute certain content or services for use by our mobile, pay-TV and broadband customers, and we have strategic partnerships with major digital players, such as Amazon. We make long-term commitments in advance even though we cannot predict the popularity of the services or ratings the programming will generate. In some instances, our commitments include minimum guarantees, which means that we are required to pay a certain agreed-upon amount regardless of the amount collected from the provision of such services. The commercial success of applications or content also depends on the quality and acceptance of other competing applications or content released into the marketplace at or near the same time.

The success of our pay-TV services depends on our ability to access an attractive selection of television programming from content providers.

The ability to provide movie, sports and other popular programming is a major factor that attracts customers to pay-TV services. We may not be able to obtain sufficient high-quality programming from third-party producers or exclusive sports content for our cable TV services on satisfactory terms or at all in order to offer compelling cable TV services, which could result in reduced demand for, and lower revenue and profitability from, our cable services.

Consumers are increasingly able to choose from a variety of platforms from which to receive content and programming.

A number of content providers have begun to sell their services through alternative distribution channels including IP-based platforms, smart-TVs and other app-compatible devices. Consumers may choose to purchase on-demand content through these alternative transmission methods, which may lead to reduced demand for our pay-TV services. If our customers choose to source their content through transmission methods that we do not offer, our customer base and revenue generation from content-related services such as pay-TV may decline, which would negatively impact our cash flow generation and return on investment in content-related services.

We may be subject to legal liability associated with providing online services or media content.

We host and provide a wide variety of services and products that enable our customers to conduct business, and engage in various online activities. The law relating to the liability of providers of these online services and products for the activities of their customers is still unsettled in some jurisdictions. Claims may be threatened or brought against us for defamation, negligence, breaches of contract, copyright or trademark infringement, unfair competition, tort, including personal injury, fraud, or other theories based on the nature and content of information that we use and store. In addition, we may be subject to domestic or international actions alleging that certain content we have generated or third-party content that we have made available within our services violates applicable law or third-party rights.

We also offer third-party products, services and content. We may be subject to claims concerning these products, services or content by virtue of our involvement in marketing, branding, broadcasting, or providing access to them, even if we do not ourselves host, operate, provide, or provide access to these products, services or content. Defense of any such actions could be costly and involve significant time and attention of our management and other resources, may result in monetary liabilities or penalties, and may require us to change our business in an adverse manner. For example, in Colombia we have faced litigation for the provision of services to customers that used our mobile services to attempt to extort money from third parties.

c.Licenses and spectrum

Available spectrum is limited, closely regulated and increasingly expensive.

The availability of spectrum is limited, closely regulated and can be expensive, and we may not be able to obtain it from the regulator or third parties at all or at a price that we deem to be commercially acceptable given competitive conditions. If we acquire spectrum through acquisition, regulators may require us to surrender spectrum to secure regulatory approval. We may need to incur significant capital expenditures in order to acquire or renew licenses or access infrastructure needed to continue to offer services to our customers or improve our current services.

Additional or supplemental licenses may be required to implement 5G technology in order to remain competitive, and we may be unable to acquire such licenses on reasonable terms or at all.

We may not be able to acquire or retain sufficient quantities of spectrum in our preferred band(s) which could impact the quality and efficiency of our networks and services and may negatively impact our profitability.

Our licenses may be suspended or revoked and we may be fined or penalized for alleged violations of law or regulations.

If we fail to comply with the conditions of our licenses or with the requirements established by the legislation or if we do not obtain permits for the operation of our networks and equipment, use of frequencies or additional licenses for broadcasting directly or through agreements with broadcasting companies, we may not have sufficient opportunity to cure any non-compliance. In the event that we do not cure any non-compliance, the applicable regulator may: levy fines; suspend or terminate our licenses, frequency permissions, or other governmental permissions; or refuse to renew licenses that are up for renewal.

Most of our licenses are granted for finite periods.

Most of our licenses are granted for specified terms, and we have no assurance that any license will be renewed upon expiration. Licenses due to expire in 2025 include our license Value Added Services (VAS) in Honduras, and AWS in Colombia.

Licenses may contain additional obligations.

Licenses may contain additional obligations, including payment obligations and requirements to cover reduced service areas or permit a more limited scope of service (for example, around prisons in El Salvador and Honduras). The cost of extending coverage to reduced service areas may exceed the revenue generated from providing such services. Licenses may also contain coverage obligations, like in Colombia where 700 MHz frequency acquisitions were paid partly with cash and partly by committing to provide coverage to 1,636 districts over the course of five years. In addition, increased regulations may impose additional obligations on operators and these obligations may affect the retention and renewal of licenses or spectrum. For more information, see “Information on the Company—Business Overview—Regulation.”

d.Quality and resilience of networks and service

Equipment and network systems failures, including as a result of climate change, a natural disaster, sabotage or terrorist attack, could negatively impact our business.

Our business is dependent on certain sophisticated critical systems, including exchanges, switches, fiber, cable headends, data centers and other key network elements, physical infrastructure and billing and customer service systems. Our technological infrastructure is vulnerable to damage and disruptions from numerous factors, including climate change, fire, flood, windstorms and other natural disasters and extreme weather events, power outages, terrorist acts, equipment and system failures, human errors and intentional wrongdoings, including breaches of our network and information technology security. For example, in 2020, our mobile network was partially affected due to storm damage in Honduras, which resulted in the deterioration of service in certain parts of the country. Ongoing risks to our network include state-sponsored censorship, sabotage, theft and poor equipment maintenance.

Inability to manage a crisis could harm our brand and lead to increased government obligations in the future.

Telecommunications networks provide essential support to first responders and government authorities in the event of natural disasters, terrorist attacks, pandemics and other similar crises. If we fail to develop and implement detailed business continuity and crisis management plans, we may be unable to provide service at the level that is required or perceived to be required by the government, the regulator, our customers and by the public at large, and this could lead to reputational harm and to new and burdensome regulatory obligations in the future.

e.Regulation

The telecommunications and broadcasting market is heavily regulated.

The licensing, construction, ownership and operation of mobile telephone, broadband and cable TV networks, and the grant, maintenance and renewal of the required licenses or permits, as well as radio frequency allocations and interconnection arrangements, are regulated by national, state, regional or local governmental authorities in the markets in which we operate, which can lead to disputes with government regulators. For example, in 2013, the Colombian regulator challenged Colombia Móvil’s license fee, stating that it should be a significantly higher amount than we had recorded, although Colombia Móvil prevailed.

Certain other aspects of mobile telephone operations, including rates charged to customers, resale of mobile telephone services, and user registrations may be subject to public utility regulation in each market. Also, because of our market share, regulators could impose asymmetric interconnection or termination rates, which could undermine our competitive position in the markets in which we operate.

Changes in regulations may disrupt our business activities and reduce our revenue and profit margins for mobile services.

Regulatory changes may reduce or prohibit the provision of our services on a temporary or long-term basis. For example, since 2014, mobile operators in El Salvador and Honduras have been required to shut down services or reduce signal capacity in and around prisons. Similar laws have been enacted in Guatemala, although these were later nullified.

Moreover, regulations which make it commercially unviable to subsidize our mobile customers’ handsets; set an expiry date on when our customers must use their prepaid minutes, data or short message service ("SMS") bundles; or prohibit certain automatic deductions to customer accounts, could reduce revenue and profit margins for mobile services. For example, in 2015, the regulator in Colombia determined that handsets and telecommunication services could not be bundled and had to be invoiced separately. This had a direct impact on handset affordability and caused a sharp decline in our handset sales. In 2016, the regulator in Paraguay extended the unused prepaid data allowance from 30 to 90 days, which impacted the frequency at which a portion of our prepaid customers purchase additional data allowances from us. In 2019, the Legislative Assembly in El Salvador made a reform to the Consumer Protection Law, which required a change in the telecommunication companies' commercial activities. The reform called for the maintenance of unused data allowances for up to 90 days and prohibited automatic renewals, changing our financial results. Additionally, the reform banned broadcasts and collection activities outside business hours, impacting our clients' churn trends and payment behavior. In 2022, the Bolivian regulator prohibited operators from automatically making deductions to prepaid customer accounts for data usage services on an on-demand basis unless the customer has expressly opted-in to receive on-demand data. As a result, when a prepaid customer uses up their data allowance, the operator cannot automatically begin charging such user on an on-demand basis and must, instead, cancel data access until such customer either purchases a new data package or accepts on-demand data.

Our MFS product may be subject to new legislation and regulation.

We provide a broad range of MFS such as payments, money transfers, international remittances, real-time loans and micro-insurance. In most markets in which we have launched MFS, the laws and regulations governing our MFS are new and evolving, and, as they develop, regulations could become more onerous, requiring licensing by or registration with local regulators, imposing additional reporting or controls or limiting our flexibility to design new products, which may limit our ability to provide our services efficiently or at all.

The lack of established laws and regulations may make it difficult to identify which licenses and approvals (if any) are necessary and the processes for obtaining them, as well as the implications of holding such licenses or receiving such approvals. For the same reason, we cannot be certain that we will be able to

maintain licenses and approvals that we previously obtained, or renew them upon their expiration. While we currently believe that some of our MFS activities fall outside the scope of licensing requirements and do not require certain approvals, there can be no assurance that our interpretations of the rules and their exemptions are or will remain consistent with those of local regulators.

We have, in most of our markets, seen that fintech legislation is evolving, particularly as it relates to anti-money laundering and suspicious activity reporting. Any such changes may require us to make additional investments in tools and resources to meet such requirements. If we are unable to modify our service provision in time to comply with any new regulatory requirements, or new regulations are applied retroactively, we may be subject to penalties and the discontinuation or restriction of our operations, which could have a material adverse effect on our business, financial condition and results of operations.

For more information on the regulatory environment in the markets in which we operate, see “Information on the Company—Business Overview—Regulation.”

f.Cybersecurity and data protection

Cyber-attacks may cause equipment failures that render our networks or systems inoperable and could cause disruptions to our customers’ operations.

Cyber-attacks may cause equipment failures that render our networks or systems inoperable and could cause disruptions to our customers’, suppliers’ and vendors’ operations. The costs associated with a major cyber-attack on Millicom could include expensive incentives offered to existing customers and business partners to retain their business, increased expenditures on cybersecurity measures and the use of alternate resources and lost revenue from business interruption and litigation. In addition, the inability to operate or use our networks and systems, even for a limited period of time, may result in loss of market share to other communications providers. Such costs and disruptions may have a significant adverse effect on our business.

Our control environment and controls may not be sufficient to prevent or rapidly detect and respond to cyber-attacks.

As a telecommunications company, we are often targeted by threat actors, who are aware that our Company manages a large amount of critical and confidential data and that the impact of a cyber-attack could have a serious impact on critical businesses and a large number of individuals in the countries in which we operate. We may be impacted by phishing, breaches, ransomware attacks, extortion, insiders or external malicious actors targeting our systems, networks and data, or incidents affecting third parties on which our business relies.

Like many other companies, Millicom has been subject to ransomware attacks, web service attacks, denial of service attacks, unauthorized access to services or data and threats related to our operations in several Latin American countries where we operate, with the most significant incidents occurring in Paraguay, Guatemala, El Salvador, Colombia and Bolivia. While the incidents were managed with a focus on minimizing the impact on customers, third parties and our services and we were able to recover and limit the loss of data, there can be no assurance that we will be able to prevent any future cyber-attacks that result in a material loss of data or other security breaches, notwithstanding the measures and control environment we have put in place.

Although we have taken and continue to take measures to prevent and mitigate cybersecurity incidents, whether caused by internal or external actors, there can be no assurance that we will be able to adequately anticipate or prevent them, as the tactics and techniques used by malicious threat actors are constantly evolving and may initially go undetected.

We collect and process customer personal data.

Our business involves the receipt, storage, and transmission of confidential information, including sensitive personal information and payment card information, confidential information about our employees, customers and suppliers, and other sensitive information about Millicom, such as our business plans,

transactions and intellectual property. Unauthorized access to confidential information may be difficult to anticipate, detect, or prevent.

Data privacy laws and regulations apply broadly to the collection, use, storage, disclosure and security of personal information that identifies or may be used to identify an individual, such as names and contact information. Many countries have additional laws that regulate the processing, retention and use of communications data (both content and metadata), and in some countries, authorities can intercept communications, sometimes directly or without our knowledge. These laws and regulations are subject to frequent revisions and differing interpretations, and have generally become more stringent over time.

Requests from local law enforcement for customer data may also come into conflict with applicable privacy and data protection laws and customer expectations, creating risks to our local businesses arising from our responses to these requests.

Since we may offer certain services accessed by, or provided to customers within, the European Union and the United States, we may be subject to the European Union and U.S. privacy and data protection regulations, which impose significant penalties for non-compliance.

In addition, most of the countries in which we operate are considering or have passed legislation imposing data privacy requirements that could increase the cost and complexity of providing our services. Although we take precautions to protect data, we cannot guarantee that our safeguards will prevent any leakage of certain data or any unauthorized use. If changes are made to data privacy laws and regulations, we may need to incur additional costs to ensure that we are in compliance with such changes, which could include investments in data processes, data collection tools or data warehouses to further protect customer and employee data.

g.Competition

Our industry is experiencing consolidation that may intensify competition among operators.

The telecommunications and cable industry has been characterized by increasing consolidation and a proliferation of strategic transactions. As a result, we are increasingly competing with larger competitors that may have substantially greater resources than we do. We expect this trend of consolidation and strategic partnering to continue. Acquisitions or strategic relationships could harm us in a number of ways. For example:

•competitors could acquire or enter into relationships with companies with which we have strategic relationships and discontinue our relationship, resulting in the loss of distribution opportunities for our services or the loss of certain enhancements or value-added features to our services; for example, if a competitor entered into partnerships or negotiated exclusive rights to premium content, this could result in consumers choosing to move away from our service offerings to those of our competitors;

•a competitor could be acquired by a party with significant resources and experience that could increase the ability of the competitor to compete with our services, as was the case when América Móvil acquired the mobile business of Telefónica in Guatemala and when a subsidiary of Liberty Latin America Ltd. acquired América Móvil's operations in Panama; and

•other companies with related interests could combine to form new, formidable competition, which could preclude us from obtaining access to certain markets or content, or which could dramatically change the market and demand for our services, as was the case with the bankruptcy of Digicel Group One Limited. If global companies that offer services such as information, social media or on-demand content services obtained or entered into distribution agreements with infrastructure partners in our markets, we could lose customers to those providers.

Consumers in our industry can change service providers relatively easily at little to no cost, which renders the competition for subscribers between operators intense.

If new competitors enter into our markets or existing competitors offer more competitively priced products or services, such as eliminating installation fees, subsidizing handsets, modems, wireless routers or set-top boxes, or offering content, channels or applications that we do not offer, our customers may move to another operator. Most of our mobile customers are prepaid, which allows them to switch operators at any

time without monetary penalty, and some of our cable operator competitors incentivize customers to accept longer contracts, making it difficult to subsequently switch operators.

Some of our customers use devices with dual SIM card capability, allowing them to also utilize our competitors' services, which may negatively affect our mobile revenue. If we are unable to develop strategies to encourage customers to retain us as their primary or sole provider, we could lose a larger percentage of our revenue to our competitors. Mobile number portability in our markets removes a disincentive to changing providers and increases competition and churn. As devices with eSIMs are introduced in our markets, allowing customers to change providers without changing their SIM cards, churn and pricing competition among providers may also increase.

If we are unable to compete effectively and match or mitigate our competitors' strategies or aggressive competitive behavior, in pricing our services or acquiring new and preferred customers, or if we are unable to develop strategies to encourage customers to retain us as their primary or sole provider, we could suffer adverse revenue impacts or higher costs for customer retention, which could, individually or together, have a material adverse effect on our business, financial condition and results of operations.

Consumers in the telecommunications industry now have many alternative means of communicating.

The proliferation of VoIP and video streaming offerings and other services delivered over the internet (referred to as “Over-the-Top” or “OTT” services) for voice, instant messaging, and video content has significantly increased competitive risk and has driven down revenue from legacy voice, SMS and linear TV services. While these alternative communication methods require usage of data, there are no guarantees that consumers will use our networks to obtain data services.

h.Environment and sustainability

Failure to comply with environmental requirements could result in monetary fines, reputational damage or other obligations.

Certain of our business operations are subject to environmental laws and regulations since they involve fuel consumption, carbon dioxide emission, and disposal of network equipment and old electronics. Environmental requirements have become more stringent over time, and pending or proposed new regulations could impact our operations or costs.

Increasing scrutiny and evolving expectations from customers, regulators, investors and other stakeholders with respect to our environmental, social and governance practices may impose additional costs on us or expose us to new or additional risks.

Companies are facing increasing scrutiny from customers, regulators, investors and other stakeholders with respect to their environmental, social and governance (“ESG”) practices. Views about ESG are diverse and rapidly changing, particularly as they relate to the environment, health and safety, diversity, labor conditions and human rights. New regulations or guidance relating to ESG standards, as well as the perspectives of customers, investors and other stakeholders regarding these standards, may affect our business activities and increase disclosure requirements, which may increase costs. If investors and other stakeholders determine that we have not made sufficient progress on or adequately addressed ESG matters, we could be subject to negative publicity in traditional or social media, and our reputation, ability to retain customers and employees, and financial condition and results of operations could be adversely affected.

i.Supplier management

We are dependent on key suppliers to provide us with products and devices.

We rely on handset distributors, manufacturers and application developers to provide us with the handsets, hardware and services demanded by our customers. The key suppliers of our handsets and set-top boxes, in terms of both volume of sales and importance to our operations, are Apple, B-Mobile, Blu, Honor, Maxwest, Motorola, OPPO, Samsung, Tecno, Vivo, Xiaomi and ZTE. We import directly from original equipment manufacturers ("OEMs"), or we source our handsets through their authorized distributors in each of our markets.

We are dependent on key suppliers to provide us with networks and systems.

We seek to standardize our network equipment to ensure compatibility, ease equipment replacement and reduce downtime of our network and contract with a limited number of international suppliers to achieve economies of scale, which means that we rely on a limited number of manufacturers to provide network and telecommunications equipment and technical support. The key suppliers of equipment and software for our existing networks are Huawei, Ericsson, Nokia, PPC, Fiberhome, Harmonic, Kaon, Vantiva, Juniper, Intraway and VMWare.

We have limited influence over these key suppliers, and even less over their suppliers and the continuity of their supply chains, which could be disrupted in many ways. Therefore, we cannot assure you that we will be able to obtain required products or services on favorable terms or at all. Any failure of key suppliers to provide software and equipment could interfere with our operations. For example, in recent years, we experienced significant disruptions in the supply of microchips due to a global shortage that affected our suppliers, which we addressed by accumulating strategic inventories and substituting alternative products to sustain our operations. While we did not experience such disruptions in 2023 or 2024, there can be no assurance that we will not be subject to future shortages or other similar disruptions, which could have a significant adverse effect on our business.

International actions including trade sanctions could disrupt or otherwise negatively impact our supply chain.

In May 2019, the U.S. government announced executive action aimed at addressing U.S. national security risks arising from the use of non-U.S. technology. In furtherance of this order, the U.S. Department of Commerce issued an interim final rule in January 2021 that allows the U.S. government to prohibit certain information and communications technology and services (“ICTS”) transactions to address U.S. national security threats. In June 2023, the U.S. Department of Commerce issued a final rule that amended the ICTS interim final rule, which clarified the scope and criteria relevant to evaluating whether certain ICTS transactions present U.S. national security threats. Although the extent and potential consequences of the U.S. government's review of ICTS transactions remain uncertain, they may have a material adverse effect on our ability to maintain and expand our networks and business. There are a number of alternative suppliers available to us; however, if we are unable to obtain adequate alternative supplies of equipment or technical support in a timely manner, on acceptable commercial and pricing terms, our ability to maintain and expand our networks and business may be materially and adversely affected.

We rely on interconnection and capacity agreements, the terms of which could be made less favorable due to market participants or regulatory changes.

Interconnection and capacity agreements are required to transmit voice and data to and from our networks. Our ability to provide services would be hampered if our access to local interconnection and international capacity was limited, or if the commercial terms or costs of interconnection and capacity agreements with other local, domestic and international carriers of data and communications were significantly altered, or if an operator is not able to provide interconnection due to operation and maintenance issues or natural disasters.

We depend upon certain third parties to operate and maintain parts of the network infrastructure we use, including certain towers and network infrastructure, and related services.

In 2023, after determining that ownership of mobile communications towers no longer confers a competitive advantage, we began the process of moving towers at more than 9,000 sites into a separate company, as further discussed under "Information on the Company—Business Overview—Property, Plant and Equipment—Tower infrastructure." Although the transfer has not yet been fully completed, we anticipate that the carved-out tower company may be ultimately owned and controlled by a third party. Further, we have sold and leased back a significant number of our towers, and we may engage in similar transactions in the future.

We also have entered into managed services agreements in certain of our markets to outsource the maintenance and replacement of our network equipment. Although the contracts impose performance obligations on the operators and tower management companies, we cannot guarantee that they will meet these obligations or implement remedial action in a timely manner, which may result in these towers or networks not being properly operated. If our managed services agreements terminate, we may be unable to find a cost-effective, suitable alternative provider, and we may no longer have the necessary expertise in-

house to perform comparable services. For example, if our tower network service provider is unable to properly maintain our towers, we may suffer a degradation in the quality or coverage of our mobile services.

We and our customers are dependent on third-party suppliers of electricity to power transmission and customer premise equipment.

Significant failure or disruption in the supply of power to the businesses and households that subscribe to our services, or to the data centers that we operate, could have a negative impact on the experience of our customers, which could result in claims against us for failure to provide services and reduce our revenue.

2.Risks related to Millicom’s business in the markets in which it operates

The outbreak of pandemics or other public health crises has had, and may again have, a significant negative effect on our operations, business and financial condition.

The outbreak of a pandemic or similar public health crises (including COVID-19) could significantly disrupt our business operations for an extended period. The measures taken to combat a pandemic or public health crisis and ameliorate its effects, such as the closing of retail stores or other distribution channels, as well as other government mandates to provide services to non-paying clients, have had, and may again have, a significant negative effect on our operations.

The full impact of a pandemic or public health crisis cannot be predicted and depends on several factors, including the geographic spread and duration of the illness, the resurgence or emergence of variant strains of the illness, the availability and effectiveness of vaccines, vaccine hesitancy, the response by governments, private sector participants and the public to contain the illness or address its impacts, and the associated disruption to business and commerce generally, all of which are highly uncertain and could have a significant adverse effect on our business.

a.Emerging Market Risks

Most of our operations are in emerging markets that may be subject to greater risks than more developed markets, including in some cases significant political, legal and economic risks.

Emerging market governments and judiciaries often exercise broad, unchecked discretion, and are susceptible to abuse and corruption and rapid reversal of political and economic policies on which we depend. Political and economic relations among the countries in which we operate are often complex and have resulted, and may in the future result, in conflicts, which could materially harm our business.

The economies of emerging markets are vulnerable to market downturns and economic slowdowns elsewhere in the world. Emerging markets are also subject to adverse global political events and geopolitical tensions, such as the ongoing conflict between Russia and Ukraine. Such events may result in sanctions, disruptions in global supply chains, military actions and macroeconomic instability, each of which may adversely affect the economies of emerging markets. As has happened in the past, financial problems or an increase in the perceived risks associated with investing in emerging economies could dampen foreign investment in these markets and materially adversely affect their economies, which may cause our business and results of operations to suffer.

Turnover of political leaders or parties in emerging markets as a result of a scheduled election upon the end of a term of service or in other circumstances may also affect the legal and regulatory regime in those markets to a greater extent than turnover in established countries. Some of the emerging markets in which we operate are susceptible to social unrest, which may lead to military conflict in some cases.

b.Strategy and strategic direction

We may not be able to successfully implement our strategic priorities.

Our strategic priorities include, among others, expansion of our high-speed data networks (4G, HFC and FTTH), facilitation of growth in our mobile data and fixed broadband segments, implementation of 5G technology transformation projects to improve our operating performance and efficiency, implementation of cost efficiency programs and the creation of, and potential sale of interests in, legal entities to separate our Towers business (including Lati International S.A.) and our Tigo Money business from our telecommunications service operations. We also regularly evaluate potential opportunities to consolidate or

form strategic partnerships or alliances with other large competitors. There can be no assurance that our strategy will be successfully implemented and will not cause changes in our operational efficiencies or structure, that it will achieve the desired financial or operational objectives or that any entities will be divested (including Lati International S.A.). In addition, the implementation of our strategic priorities could result in increased costs, conflicts with employees, local shareholders and other stakeholders, business interruptions, and difficulty in recruiting and retaining key personnel. Further, we could enter into partnerships or strategic alliances that require significant investment or other undertakings from us (including non-compete agreements) or that limit our financial flexibility or pose limitations on our ability to control or exercise significant influence over companies or businesses in which we have an ownership stake or over which we exercise control, which could, in turn, result in our having to deconsolidate assets, liabilities and results of operations associated with those businesses.

Lack of sufficient information or poor quality of available information regarding our industry, operations or markets may lead to missed opportunities or inefficient capital allocation.

As the factors we consider in formulating our strategy change (including information, such as customer data insights or new markets into which we may consider entering), we face the risk of not having access to sufficient industry, operational or market data inputs to properly inform our decision-making or needing to rely on poor-quality information. There is also a risk that the data to which we have access will be analyzed improperly, if the relevant personnel lack appropriate experience, oversight, or relevant skill sets in data analysis, including through insufficient consideration of interrelationships of key variables such as market dynamics, trends, availability of cash and resources, agility, opportunities and risk factors affecting our business. If we are forced to make assumptions regarding key variables and are unable to consider alternatives to, and consequences of, strategic decisions on a fully informed basis, it may lead to missed opportunities or inefficient capital allocation that could have an adverse effect on our business, financial condition or results of operations.

We may not achieve the anticipated benefits following the acquisition of the remaining 45% equity interest in our Guatemala business.

On November 12, 2021, we signed and closed an agreement to acquire the remaining 45% equity interest in our Guatemala joint venture business from our local partner for $2.2 billion in cash. In November 2021, we obtained bridge financing to fund the acquisition, which we refinanced in part with the issuance of equity and long-term debt. We also consolidated the indebtedness from our Guatemala joint venture business in connection with the acquisition. Our leverage and debt service requirements may make it more difficult for us to capitalize on changes in market conditions or other strategic opportunities. While we have taken, and will continue to take, steps to facilitate the growth of our operations in Guatemala and improve our operating performance and efficiency, our strategy may ultimately prove to be unsuccessful. If we are unable to generate sufficient cash flow from our operations in Guatemala and future borrowings are not available, we may not be able to pay our indebtedness or fund our other liquidity needs, which could have a material adverse effect on our business, financial condition and results of operations.

c.Industry structure, market position and competition

We face intense competition from other larger telecommunications and cable and broadband providers.

The markets in which we operate are highly competitive. Our main mobile and fixed competitors include major international and regional telecommunication providers such as América Móvil, Telefónica and Liberty Latin America. Many of our main competitors have substantially greater resources than we do in terms of access to capital. Some of our competitors are state-owned entities, which may prioritize social objectives over profitability. In some of our markets, our competitors may have access to more spectrum and provide greater or better area coverage, and they may face fewer regulatory burdens than we do.

We have a weaker market position in mobile services and face a challenging competitive environment in Colombia, our largest market.

Relative to our other markets, the mobile services sector in Colombia is characterized by having more competitors, including América Móvil and Telefónica, which are larger than us, and by having more stringent regulatory conditions. Relative to our other markets for mobile services, our competitive position is also weaker in Colombia, where we are the third largest mobile operator. Additionally, new competitors have been and may continue to be awarded mobile spectrum, including WOM, which entered the Colombian market in April 2021.

Given the importance of Colombia to our results, any failure to sustain or improve our position in the mobile services sector could have a material impact on our consolidated financial results.

Competition is driven by a number of factors, most notably price and increasingly customer experience.

Within our markets, operators compete for customers principally on the basis of price, promotions, services offered, advertising and brand image, quality and reliability of service, mobile coverage and overall customer experience. Telecom services are largely commoditized services, and the ability to differentiate these services among operators is limited. Competition may result in pricing pressure, reduced margins and profitability, an increase in customer churn and reduced revenue and market share.

The effects of competition have been exacerbated by recent inflationary pressures, and the need to increase prices for our products and services has become increasingly more common. Competitive pressures could prevent us from implementing or sustaining such price increases, or implementing price increases that are commensurate with inflation, which may have a material adverse impact on our business, financial condition and results of operations.

There may be more mobile operators than the market is able to sustain.

Additional licenses may be awarded in already competitive markets, and regulators may incentivize competition by offering favorable conditions to new entrants, such as holding spectrum auctions in which certain blocks of spectrum are reserved for new entrants, or by capping the amount of spectrum that existing players can acquire, as in Colombia's 2019 auction of licenses to use a total of 40 MHz in the 700 MHz band.

Entry by new competitors may have a significant disruptive effect on our markets.

New competitors may enter our markets with pricing or other product or service strategies, primarily designed to gain market share, that are significantly more competitive than our offers, leading to, for example, significant price competition and lower margins or increased churn.

In certain of our mobile markets, such as Colombia, our competitors may have a dominant market position.

Having a dominant market position may provide our competitors with various competitive advantages including from economies of scale, access to spectrum, the ability to significantly influence market dynamics and market regulation.

Our competitors may be able to provide better pay-TV services than we are able to provide.

Our pay-TV services compete with other pay-TV services that may offer a greater range of channels to a larger audience, reaching a wider area distribution (especially in rural areas) for a lower price than we charge for our pay-TV services. We also compete with satellite distribution of free-to-air television programming, which viewers can receive by purchasing a satellite dish and a set-top box without any physical cabling. Furthermore, our cable networks are subject to the risk of overbuild and our pay-TV content is subject to the possibility of wireless substitution.

Many of the mobile telecommunications markets in which we operate have high mobile penetration levels, inhibiting growth opportunities.

The markets in which we operate have mobile phone service penetration levels that typically exceed 100% of the population. Although there are some opportunities for further growth, our efforts to develop additional sources of revenue may not be successful. Therefore, high mobile penetration rates could constrain future growth and produce an intensification of pricing pressures on all of our mobile services, which could adversely affect our future profitability and return on investments.

We may not be able to achieve market acceptance of our mobile financial services.

Although the use of mobile financial services and digital payments has increased throughout the world, there can be no assurance that this increase will result in the acceptance of our MFS across the markets in which we operate. For example, our Tigo Money business is currently deployed in several of our markets, and, as of December 31, 2024, we had a total of 3.7 million active users. However, we may be unable to achieve

the required level of market acceptance in order for us to recover the investment costs involved in developing and launching such services, and any failure to achieve such acceptance may cause us to reduce our product offerings or exit certain of our markets.

The future market acceptance of our MFS depends on a variety of factors, including community trust in digital financial services and companies that are not traditional financial institutions, entrenched preferences in traditional payment methods, and the availability of alternative MFS that are more popular or widely accepted by the population.

d.Customer base and customer experience

A significant proportion of our mobile revenue is generated from prepaid customers and is short-term in nature.

Prepaid customers do not sign service contracts and may be more likely than postpaid customers to switch mobile operators and take advantage of promotional offers by other operators. Many of our prepaid mobile customers subscribe to short-term packages that are valid for only one day. As a result, we cannot be certain that prepaid customers or short-term data package customers will continue to use our services in the future. Prepaid customers generated approximately 60% of our mobile service revenue during 2024.

The transition to more subscription-based businesses creates new challenges.

Our transition toward an increasingly subscription-based revenue model has implications for our personnel, systems, and business procedures, as we must dedicate increasing levels of management attention and resources toward managing and mitigating risks related to accounts receivables and collections, as well as billing and customer care. If we are unable to implement and manage the information systems and to properly train our employees, we could experience elevated levels of customer churn and bad debt, which would negatively impact our financial results.

e.Political

Many of the countries in which we operate have a history of political and social instability.

Some of the countries in which we operate may be subject to greater political and economic risk than developed countries. Some of the countries in which we operate suffer from political instability, civil unrest, or war-like actions by anti-government insurgent groups. These problems may continue or worsen, potentially resulting in significant social unrest or civil war. For example, Bolivia, Panama and Guatemala, and to a lesser extent, Colombia, have recently experienced civil, social and political unrest.

Any political or social instability or hostilities in the markets in which we operate can hinder economic growth and reduce discretionary consumer spending on our services, and may result in damage to our networks or prevent us from selling our products and services.

We face a number of risks as a result of political and social instability in the countries in which we operate, ranging from the risk of network disruption, sometimes resulting from government requests to shut down our networks as well as forced and illegal abuse of our network by political forces, to the need to evacuate some or all of our key staff from certain countries, in which case there is no guarantee that we would be able to continue to operate our business as previously conducted in such countries. Any of these events would adversely affect our results of operations.

f.Legal and regulatory

The nature of legislation and rule of law in emerging markets may affect our ability to enforce our rights under licenses or contracts or defend ourselves against claims by third parties.

The nature of much of the legislation in emerging markets, the lack of consensus about the scope, content and pace of economic and political reform and the rapid evolution of the legal systems in emerging markets, place the enforceability and, possibly, the constitutionality of, laws and regulations in doubt and result in ambiguities, inconsistencies and anomalies. These factors could affect our ability to enforce our rights under our licenses or our contracts, or to defend our company against claims by other parties. For example, if we enter litigation proceedings with a third party in a country in which we operate, and within a legal system which may be less transparent and less robust in its judgment and rulings, we may face

penalties or decrees that compel us to cease or partially cease the provision of certain of our services or the operation of our networks, or invalidate or suspend our licenses or rights therein.

New or proposed changes to laws or new interpretations of existing laws in the markets in which we operate may harm our business.

We are subject to a variety of national and local laws and regulations in the countries in which we do business. These laws and regulations apply to many aspects of our business. Violations of applicable laws or regulations could damage our reputation or result in regulatory or private actions with substantial penalties or damages. In addition, any significant changes in such laws or regulations or their interpretation, or the introduction of higher standards or more stringent laws or regulations, could have an adverse impact on our business, financial condition, results of operations and prospects. For example, in Colombia in 2017, the regulator introduced caps to wholesale rates on mobile services, which forced us to lower our prices for both voice and data services, and it also cut interconnection rates.

Developing legal systems in the countries in which we operate create a number of uncertainties for our businesses.

The legal systems in many of the countries in which we operate are less developed than those in more established markets. This creates uncertainties with respect to many of the legal and business decisions that we make, including, among others, potential for negative changes in laws, gaps and inconsistencies between the laws and regulatory structure, difficulties in enforcement, broad regulatory authority held by telecommunications regulators, inconsistency and lack of transparency in the judicial interpretation of legislation and corruption in judicial or administrative processes or systems. We may not always have access to efficient avenues for appeal and may have to accept the decisions imposed upon us. For more information concerning the legal proceedings to which we are subject, see “Financial Information—Consolidated Statements and Other Financial Information—Legal Proceedings.”

g.Macro-economic and currency

The economies of emerging markets, including those in which we operate, are vulnerable to market downturns and economic slowdowns elsewhere in the world.

Telecommunications in emerging markets in general and in our markets in particular, account for a significant part of gross domestic product (“GDP”) and disposable income. As such, any change in economic activity level may impact our business. Furthermore, as consumers in emerging markets have relatively lower levels of disposable income, the demand for our products and services is significantly exposed to the risk of economic slowdown.

As has happened in the past, financial problems or an increase in the perceived risks associated with investing in emerging economies could dampen foreign investments in these markets and materially adversely affect their economies. An economic downturn, a substantial slowdown in economic growth or a deterioration in consumer spending could have an adverse effect on the level of demand for our products and services and our growth. We are particularly susceptible to any deterioration in the economic environment of the countries in which we have our largest operations, namely Colombia, Guatemala, Paraguay, Honduras, Panama and Bolivia.

Changes in economic, political and regulatory conditions in the United States or in U.S. laws and policies governing foreign trade and foreign relations could have an impact on the economies in which we operate.

Any decision taken by the U.S. government that has an impact on the Latin American economy, such as reducing commercial activity between the countries in which we operate and the United States, increasing tariffs, limiting immigration, increasing interest rates or slowing direct foreign investments, could adversely affect the disposable income of consumers. In addition, a slowdown in the U.S. economy may have an adverse impact on the level of U.S. dollar remittances that form a large part of the GDP of many of the countries in which we operate.

Fluctuations or devaluations in local currencies in the markets in which we operate against our U.S. dollar reporting as well as our ability to convert these local currencies into U.S. dollars to make payments, including on our indebtedness, could materially adversely affect our business, financial condition and results of operations.

A significant amount of our costs, expenditures and liabilities are denominated in U.S. dollars, including capital expenditures and borrowings. We mainly collect revenue from our customers in local currencies, and there may be limits to our ability to convert these local currencies into U.S. dollars. Local currency exchange rate fluctuations in relation to the U.S. dollar may have an adverse effect on our earnings, assets and cash flows. To the extent that our operations retain earnings or distribute dividends in local currencies, the amount of U.S. dollars ultimately received by MIC S.A. is also affected by currency fluctuations.

A significant amount of our debt and long-term financial commitments are denominated in U.S. dollars.

Where possible and where financially viable, we borrow in local currency to mitigate the risk of exposure to foreign currency exchange. Our ability to reduce our foreign currency exchange exposure may be limited by a lack of long-term financing in local currencies or derivative instruments in the currencies in which we operate. As such, there is a risk that we may not be able to finance local capital expenditure needs or reduce our foreign exchange exposure by borrowing in local currency. For more information, see “Quantitative and Qualitative Disclosures About Market Risk—Foreign currency risk.”

Due to the lack of available financial instruments in many of the countries or currencies in which we operate, we may not be able to hedge against foreign currency exposures.

We had net foreign exchange losses of $43 million in fiscal year 2024 compared to net foreign exchange gains of $31 million in fiscal year 2023 and net foreign exchange losses of $84 million in fiscal year 2022. At the operational level, we seek to match the currencies of our cash inflows and outflows, but while this practice reduces, it does not eliminate, our significant foreign exchange exposure to the U.S. dollar.

The governments of the countries in which our operations are located may impose foreign exchange controls that could restrict our ability to receive funds from the operations.

Substantially all our revenue is generated by our local operations, and MIC S.A. is reliant on its subsidiaries’ and joint ventures’ ability to transfer funds to it. None of the foreign exchange controls that exist in the countries in which our companies operate significantly restricts the ability of our operating companies to pay interest, dividends, technical service fees, and royalty fees or repay loans by exporting cash, instruments of credit or securities in foreign currencies. However, foreign exchange controls may be strengthened, or introduced, which could restrict MIC S.A.’s ability to receive funds.

In addition, in some countries it may be difficult to convert local currency into foreign currency due to limited liquidity in foreign exchange markets. These restrictions may constrain the frequency for possible upstreaming of cash from our subsidiaries to MIC S.A. in the future. These and any similar controls enacted in the future may cause delays in accumulating significant amounts of foreign currency, and increase foreign exchange risk, which could have an adverse effect on our results of operations.

We are exposed to the potential impact of any alteration to, or abolition of, foreign exchange which is “pegged” at a fixed rate against the U.S. dollar.

Any “unpegging,” particularly if the currency weakens against the U.S. dollar, could have an adverse effect on our business, financial condition or results of operations. Currently, Bolivia operates a fixed peg to the U.S. dollar. However, in light of the recent shortage of U.S. dollars, the increased use of alternative currencies such as the Chinese Yuan, and the increasing threat of an economic downturn, there can be no assurance that such peg will be maintained in the future.

h.Taxation

Unpredictable tax systems give rise to significant uncertainties and risks that could complicate our tax strategy and business decisions.

The tax laws and regulations in the markets in which we operate are complex and subject to varying interpretations. The tax authorities in the markets in which we operate are often arbitrary in their interpretation of tax laws, as well as in their enforcement and tax collection activities. Our interpretations and application of the tax and regulations could differ from that of the relevant governmental taxing authority. Tax declarations are subject to review and investigation by a number of authorities, which are empowered to impose fines and penalties on taxpayers, and in some cases criminal penalties on company personnel. Tax audits may result in additional costs to our Group if the relevant tax authorities conclude that entities of the Group did not satisfy their tax obligations in any given year. Such audits may also impose additional burdens

on our Group by diverting the attention of management resources. The outcome of these audits could harm our business, financial condition, results of operations, cash flows or prospects. For example, on March 28, 2022, the supreme court in one of the jurisdictions in which we operate issued a $16.2 million ruling against our business, primarily for taxes related to incoming international calls and the deductibility of interest expenses in 2010. We are also addressing tax disputes with local tax authorities in several jurisdictions, further described under “Financial Information—Consolidated Statements and Other Financial Information—Legal Proceedings—Tax disputes.”

In the United States, the Trump administration indicated the intent to propose significant changes to the U.S. tax system. Many aspects of these potential proposals are unclear or undeveloped, and we are unable to predict which, if any, U.S. tax reform proposals will be enacted into law, and what effects any enacted legislation might have on our tax liabilities. In addition, the Trump administration indicated that the United States may impose retaliatory measures with respect to jurisdictions that have or are likely to put in place tax rules that are extraterritorial or disproportionately affect U.S. companies. The likelihood of these changes being enacted or implemented is unclear. We are currently unable to predict whether such changes will occur and, if so, the ultimate impact on our business.

Adverse decisions of tax authorities or changes in tax treaties, laws, rules or interpretations could have a material adverse effect on our business, results of operations, financial condition or cash flows.

The organizational structure and business arrangements between the various legal entities in the group may give rise to taxation-related risks, including risks related to the pricing of services which might be challenged if not made on an arm’s-length basis and the taxation of shell entities.

Tax authorities could argue that some of the services provided among the various legal entities in the Group are on terms more favorable than those that could be obtained from independent third parties and assess higher taxes or fines in respect of the services MIC S.A. provides.

i.Litigation and claims

Some of the litigation or claims that we face can be complex, costly, and highly disruptive to our business operations.

From time to time, in the ordinary course of our business, we are involved in legal proceedings. Some of these legal proceedings can be complex, costly, and highly disruptive to our business operations. Certain of these proceedings may be spurious in nature and may demand significant energy and attention from management and other key personnel. For example, in Tanzania in June 2016, we were served with a complaint by a third party seeking to exert rights as a shareholder of MIC Tanzania Public Limited Company. While this claim was eventually dismissed, it absorbed a significant amount of management time and resulted in additional costs. We regularly face significant litigation involving inflated claims for damages. The risks associated with these cases may be exacerbated by a lack of transparency in the judicial systems of the markets in which we operate. The assessment of the outcome of legal proceedings, including our potential liability, if any, is a highly subjective process that requires judgments about future events that are not within our control. The amounts ultimately received or paid upon settlement or pursuant to final judgment, order or decree may differ materially from amounts accrued in our financial statements. In addition, litigation or similar proceedings could impose restraints on our current or future manner of doing business. For example, if we enter litigation proceedings with a regulator in a country in which we operate, we may face penalties or decrees that compel us to cease or partially cease the provision of certain of our services or the operation of our networks.

j.Business conduct

We may not be able to fully mitigate the risk of inappropriate conduct by our employees, business partners and counterparties.

Millicom’s employees interact with customers, contractors, suppliers and counterparties, and with each other, every day. All employees are expected to respect and abide by the Group's values and Code of Conduct, commonly referred to as the “Sangre Tigo” culture. While Millicom takes numerous steps to prevent and detect inappropriate conduct by employees, contractors and suppliers that could potentially harm the Group's reputation, customers, or investors, such behavior may not always be detected, deterred or prevented. The consequences of any failure by employees to act consistently with the “Sangre Tigo”

expectations could include litigation, regulatory or other governmental investigations or enforcement actions.

We are subject to anti-corruption and anti-bribery laws.

We are subject to a number of anti-corruption laws in the countries in which we operate and are located, in addition to the Foreign Corrupt Practices Act (“FCPA”) in the United States and the Bribery Act in the United Kingdom. Our failure to comply with anti-corruption laws applicable to us could result in penalties, which could harm our reputation and harm our business, financial condition, results of operations, cash flows or prospects. The FCPA generally prohibits covered companies, their officers, directors and employees and their intermediaries from making improper payments to foreign officials for the purpose of obtaining or keeping business and/or other benefits. We operate in countries which pose elevated risks of corruption violations, and in certain of our markets, we have been and may continue to be subject to governmental investigations that include the telecommunications sector. If we are not in compliance with anti-corruption laws and other laws governing the conduct of business with government entities and/or officials (including local laws), we may be subject to criminal and civil penalties and other remedial measures. Moreover, investigations of any actual or alleged violations of such laws or policies related to us could be time consuming, distracting to management and expensive, with the potential to harm our business, financial condition, results of operations, cash flows or prospects. For example, in late 2015 we reported to the U.S. Department of Justice (“DOJ”), as well as to law enforcement authorities in Sweden, potential improper payments made on behalf of our joint venture in Guatemala. In 2016 we received notification from the Swedish Public Prosecutor that its preliminary investigation had been discontinued. In 2018, the DOJ informed us that it was closing its investigation without action. More recently, in April 2022, we received a subpoena from the DOJ requesting information concerning our business in Guatemala (“Tigo Guatemala”), including information related to the purchase in 2021 of our former joint venture partner’s interest in Tigo Guatemala and information related to any contacts with certain Guatemalan government officials. The subpoena also requested information concerning our operations in other countries in Latin America. In May 2023, we received a second subpoena from the DOJ requesting additional information regarding Tigo Guatemala. We are cooperating with the DOJ. At this time, we cannot predict the ultimate scope, timing or outcome of this matter.

Our anti-corruption policies, procedures and internal controls may not be effective in complying with anti-corruption laws.

We regularly review and update our policies, procedures and internal controls designed to provide reasonable assurance that we, our employees, joint ventures, distributors and other intermediaries comply with the anti-corruption laws to which we are subject. For example, our business in Guatemala retained external legal counsel to review its policies and procedures related to anti-corruption issues, including examining certain allegations of improper payments made several years ago. However, anti-corruption policies, procedures and internal controls are not always effective against this risk. We cannot assure you that such policies or procedures or internal controls work effectively at all times or protect us against liability under these or other laws for actions taken by our employees, joint ventures, distributors and other intermediaries with respect to our business or any businesses that we may acquire.

Our MFS service is complex and increases our exposure to fraud and money laundering.

Our MFS product has been developed through different distribution channels, and despite measures that we have taken or will take to adequately secure our payment systems, we remain susceptible to potentially illegal or improper uses of our payment services. Risks may include the use of our payment services in connection with fraudulent sales of goods or services, sales of prohibited or restricted products and money laundering.

Our policies and procedures may not be fully effective in identifying, monitoring and managing these risks. For example, we are not able to monitor the sources and uses of funds that flow through our MFS application, Tigo Money, in every case. As a result, we may be held liable for fraudulent transactions or transactions that violate trade sanctions or other legal or regulatory requirements, and an increase in negative publicity regarding our payment systems could harm our reputation and reduce consumer confidence in our services. In addition, we may face legal actions or regulatory sanctions as a result of any such activity.

Our services also involve cash handling, which exposes us to the risk of fraud and money laundering. In certain of our markets, we must keep our customers’ MFS cash in local currency demand deposits in local banks and ensure customers’ access to MFS cash, exposing us to local banking risk.

Anti-money laundering laws are often complex. We endeavor to conform to the highest standards but cannot be certain that we will be able to fully meet all applicable legal and regulatory requirements at all times. Violations of anti-money laundering laws or other regulations applicable to our MFS offerings could expose us to monetary fines or other legal actions or regulatory sanctions, which could have a material adverse effect on our business, financial condition and results of operations.

We may incur significant costs from fraud, which could adversely affect us.

Our high profile and the nature of the products and services that we offer make us a target for fraud. Many of the markets in which we operate lack fully developed legal and regulatory frameworks and have low conviction rates for fraudulent activities, decreasing deterrence for such schemes. We have been in the past and may in the future be susceptible to fraudulent activity by our employees or third-party contractors despite having robust internal control systems in place across our operations, which could have a material adverse effect on our results of operations.

We also incur costs and revenue losses associated with the unauthorized or unintended use of our networks, including administrative and capital costs associated with the unpaid use of our networks, as well as with detecting, monitoring and reducing incidences of fraud. Fraud also impacts interconnection costs, capacity costs, administrative costs and payments to other carriers for unbillable fraudulent roaming charges. Any continued or new fraudulent schemes could have an adverse effect on our business, financial condition and results of operations.

Our risk management and internal controls may not prevent or detect fraud, violations of law or other inappropriate conduct.

If any of our customers, suppliers, or other business partners receive or grant inappropriate benefits or use corrupt, fraudulent or other unfair business practices, we could be subject to legal sanctions, penalties and harm to our reputation. Given our international operations, group structure, and size, our internal controls, policies and our risk management practices may not be adequate in preventing, detecting or responding to any such incidents which could have a material negative impact on our reputation, business activities, financial position and results of operations.

We may be directly or indirectly affected by U.S. or other international sanctions laws, which may place restrictions on our ability to interact with business partners or government officials.

We operate in certain countries in which international sanctions may be imposed by the U.S., the U.K. or the European Union, and we may be required to comply with such sanctions. Such sanctions may restrict our ability to implement our strategy or conduct our business in the manner in which we expect. For example, in response to the November 2021 presidential election in Nicaragua, the U.S., the EU and the U.K. announced sanctions against the Nicaraguan Public Ministry and various Nicaraguan institutions and government officials, including the deputy director general and director general of TELCOR, the nation's principal telecommunications regulator. In October 2022, these sanctions were subsequently expanded by the United States, and the U.S. government also imposed visa restrictions on over 500 Nicaraguan individuals with ties to the Nicaraguan government. Concurrently, the European Union broadened its existing sanctions to TELCOR and seven Nicaraguan individuals, including the director of TELCOR. Finally, several Nicaraguan government officials and other key actors are currently included on the Specially Designated Nationals and Blocked Persons list of the U.S. Office of Foreign Assets Control, as well as the U.K. and EU sanctions lists. While it remains uncertain what impact current and future sanctions may have on our operations in Nicaragua and other markets, they may have a material adverse effect on our ability to maintain and expand our networks and business.

k.People, health and safety

Threats to the safety of our employees or contractors could affect our ability to provide our services.

Heightened states of danger may exist in certain of the countries in which we operate, including as a result of civil unrest, criminal activity, and the threat of natural or man-made disasters. Such events can pose significant risks to the health and safety of our employees and contractors and may impede or delay our

ability to provide services to our customers or potential customers. In those locations, we may incur additional costs to maintain the safety of our personnel, customers, suppliers, and contractors. Despite the precautions, the safety of our personnel, customers, suppliers, and contractors in these locations may continue to be at risk.

Enforcement of standards of safety and the promotion of a culture of safety may not prevent the frequency or severity of health and safety incidents.

Although we implement and provide training on health and safety matters, particularly related to the risks of working on telecommunications towers or on TV poles, there is no guarantee that our employees or our contractors will comply with applicable safety standards. For example, in 2024, we unfortunately suffered one employee fatality and two fatalities in our contracted services. If we fail to implement these procedures or if the procedures we implement are ineffective, we may suffer the loss of, or injury to, our employees or contractors, as well as expose ourselves to possible litigation and reputational harm.

l.Brand and reputation

Failing to maintain our intellectual property rights and the reputation of our brands would adversely affect our business.

Our intellectual property rights, including our key trademarks and domain names, including our Tigo brand name, which is well known in the markets in which we operate, are extremely important assets and contribute to our success in our markets. If we are unable to maintain the reputation of and value associated with them, we may not be able to successfully retain and attract customers. Furthermore, our reputation may be harmed if any of the risks described in this “Risk Factors” section materialize. Any damage to our reputation or to the value associated with our Tigo brand could have a material adverse effect on our business, financial condition and results of operations.

Impairment of our intellectual property rights would adversely affect our business.

We rely upon a combination of trademark and copyright laws, database protections and contractual arrangements, where appropriate, to establish and protect our intellectual property rights. However, intellectual property rights are especially difficult to protect in many of the markets in which we operate. In these markets, the regulatory agencies charged to protect intellectual property rights are inadequately funded, legislation is underdeveloped, piracy is commonplace, and enforcement of court decisions is difficult. The diversion of our management's time and resources along with potentially significant expenses that could be involved in protecting our intellectual property rights in our markets, or losing any intellectual property rights, could materially adversely affect our business, financial condition and results of operations.

Failing to manage unauthorized access to our services and networks could adversely affect our business.

Our ability to increase or maintain our market share and revenue is partly dependent on the controlled access to our services and networks. Sophisticated piracy techniques are continuously evolving, and preventing unauthorized use of our services and networks is inherently difficult. Although we have taken and continue to take measures designed to prevent unauthorized access to our services and networks, any unauthorized use could harm our relationships with our content providers or result in a loss of revenue, which may adversely affect our business, financial condition and results of operations.

m.Workforce

A significant portion of our workforce is represented by labor unions, and we could incur additional costs or experience work stoppages as a result of the renegotiations of our labor contracts.

As of December 31, 2024, approximately 13% of our employees participated in collective employment agreements. While we have collective bargaining agreements in place, we could incur significant additional labor costs and/or experience work stoppages as a result of subsequent negotiations or new minimum wage legislation, which could adversely affect our business operations. In addition, we cannot predict what level of success labor unions or other groups representing employees may have in further organizing our workforce or the potentially negative impact they would have on our operations. Furthermore, our strategic objectives may include divestitures of certain business lines, internal restructuring and other activities that impact employees. We cannot assure you that we will be able to maintain a good relationship with our labor unions and works council. Any deterioration in our relationship with our unions and works council could result in

work stoppages, strikes or threats to take such an action, which could disrupt our business and operations materially and adversely affect the quality of our services and harm our reputation.

3.Risks related to Millicom’s size and structure and leadership

a.Size - capacity and limitations

The amount, structure and obligations connected with our debt could impair our liquidity and our ability to expand or finance our future operations.

As of December 31, 2024, our consolidated indebtedness excluding lease liabilities was $5,815 million, of which MIC S.A. incurred $2,401 million directly, and MIC S.A. guaranteed $217 million of indebtedness incurred by its subsidiaries. Including lease liabilities, our consolidated indebtedness was $6,769 million as of December 31, 2024. In addition, at December 31, 2024 our joint venture in Honduras, which is non-recourse to MIC S.A., had $364 million of debt and lease liabilities of $87 million.

We may incur additional debt in the future. Although certain of our outstanding debt instruments contain restrictions on the incurrence of additional indebtedness, these restrictions are subject to a number of significant qualifications and exceptions and, under certain circumstances, the amount of indebtedness that could be incurred in compliance with these restrictions could be substantial. The acquisition of additional debt could, among other things, require us to dedicate a substantial portion of our cash flow to payments on our debt, place us at a competitive disadvantage compared to competitors who might have less debt, restrict us from pursuing strategic acquisitions or reduce our ability to pay dividends or implement share buybacks and prevent us from complying with our dividend policy.

We have incurred and assumed, and expect to incur and assume, additional indebtedness in connection with recent acquisitions.

We funded our acquisitions in Panama and Nicaragua mainly by incurring additional indebtedness, including through the issuance of a $750 million 6.25% bond on March 25, 2019, and the issuance by our subsidiary Telecomunicaciones Digitales, S.A. (formerly known as Cable Onda S.A.) of a $600 million 4.5% bond in November 2019. Additionally, during 2022, we refinanced the $2,150 million bridge loan that we obtained to fund the acquisition of the remaining 45% equity interest in our joint venture business in Guatemala with the issuance of new long-term debt by our local subsidiary and new equity.

Our increased indebtedness following consummation of these or other acquisitions could have the effect, among other things, of reducing our flexibility to respond to changing business and economic conditions as well as reducing funds available for capital expenditures or acquisitions, and creating competitive disadvantages for us relative to other companies with lower indebtedness levels.

b.Portfolio of operations

Most of our operations are in emerging markets and may be subject to greater risks than similar businesses in more developed markets.

Investors in emerging markets should be aware that these markets are subject to greater risks than more developed markets, including in some cases significant political, legal and economic risks. Investors should fully consider the significance of the risks involved in investing in a company with significant operations in emerging markets and are urged to consult with their own legal, financial and tax advisors.

We pursue acquisitions, investments and merger opportunities from time to time which may subject us to significant risks, and there is no assurance that we will be successful or that we will derive the expected benefits from these transactions.

From time to time, we pursue acquisitions of, investments in strategic partnerships and mergers with businesses (including other providers that we compete with), technologies, services and/or products that complement or expand our business. Some of these transactions are, and other potential transactions could be, significant relative to the size of our business and operations. For example, on March 12, 2025, we entered into a definitive agreement to acquire 67.5% of Telefónica Colombia, or Telecomunicaciones S.A. ESP BIC ("Coltel"). Pursuant to the agreement, we also agreed to participate in the public sale process to acquire the remaining 32.5% of Coltel held by La Nación and other investors, and to participate in a separate public sale process to acquire the remaining equity interest in our existing operations in Colombia held by Empresas

Públicas de Medellín. Our aggregate investment in these transactions is expected to be approximately $1 billion; however, there are numerous factors beyond our control that could affect the total amount of the investment, including but not limited to the prices fixed by the public sale processes.

Further, we may pursue other strategic transactions that could subject us to significant risks, such as the definitive agreement that we entered into in August 2024 with Liberty Latin America, one of our competitors in Costa Rica. Pursuant to the agreement, we expect to combine our operations in Costa Rica in a cashless merger in which we will retain a minority interest of approximately 14%. The merger is subject to customary closing conditions, including regulatory approvals, and is expected to close during the second half of 2025.

These transactions involve, and any similar transactions in the future could involve, a number of risks and present financial, managerial, governance and operational challenges, including: diverting management's attention from running our existing business or from other viable acquisition or investment opportunities; incurring significant transaction expenses; increased costs to integrate financial and operational reporting systems, technology, personnel, customer base and business practices of the businesses involved in any such transaction with our business; not being able to integrate our businesses in a timely fashion or at all; loss of control or significant influence, potential exposure to material liabilities not discovered in the due diligence process or as a result of any litigation arising in connection with any such transaction; and failure to retain key management and other critical employees.

Moreover, we may not be able to successfully complete acquisitions, mergers and strategic partnerships due to various challenges, such as the failure to obtain required regulatory approvals or strong competition from our competitors and other prospective acquirers who may have substantially greater resources than we do in terms of access to capital and may be able to pay more than we can with respect to merger or acquisition opportunities (which may include other participants in the public sale processes for the equity interests in Coltel held by La Nación and other investors and the equity interests in our existing operations in Colombia held by Empresas Públicas de Medellín).

There can be no assurance that we will be able to complete such transactions in the manner that we anticipate or at all, or that we will realize the expected operating efficiencies, synergies, cost savings, revenue enhancements or other benefits from such transactions. Any inability to realize the full extent of the anticipated benefits from such transactions could have a material adverse effect on our business, financial condition and results of operations.

Divestitures or restructuring of assets and businesses subject us to significant risks and may not realize expected benefits.

We may seek to divest or restructure existing operations and investments in ways that enhance the optionality for certain assets and facilitate the attraction of growth capital, such as our plans to create new organizational structures for our Towers and Tigo Money businesses. Any such divestiture or restructuring could involve a number of risks and could present financial, managerial and operational challenges including: diverting management attention from running our existing business or from pursuing other strategic opportunities; incurring significant transaction expenses; maintaining certain liabilities or obligations to indemnify the buyer of the divested business as part of the sale conditions; and the possibility of failing to properly manage the newly created entity or time the exit to achieve an optimal return.

Furthermore, the timing of divestitures and restructurings of assets and businesses may not result in optimal returns, and the amount and timing of proceeds or expected returns may be lower than our initial investment or the corresponding carrying value on our balance sheet. For example, we were unable to obtain any proceeds from the divestiture of our joint venture in Ghana.

Our ability to make significant decisions in certain of our operations may depend in part upon the consent of independent shareholders.

We have local shareholders in certain markets that exercise significant control, including a non-controlling partner in Colombia and a joint venture partner in Honduras. In these operations, our ability to make significant strategic decisions or to receive dividends or other distributions may depend in part upon the consent of current or future independent shareholders, and our operations may be negatively affected in the event of disagreements with or breaches by our partners.

Further, our ability to successfully operate our business in Colombia may be hindered due to the governance arrangements for that business, which require the approval of our local partner to make certain

decisions. For example, our operations in Colombia were constrained by the near-term maturity of a significant amount of debt, which led us to make a joint capital contribution with our local partner in October 2023 and thereby avoid the bankruptcy of our operations in Colombia. Although we ultimately reached an agreement with our local partner on the capital contribution, there can be no assurance that our business in Colombia will satisfy its debt obligations in the future or that we could come to an agreement with our local partner to satisfy such obligations or modify our agreements with our local partners as part of our strategy for Colombia.

Millicom's central functions provide essential support and services to our operating subsidiaries and joint ventures.

These services include, financing, procurement, technical and management services, business support services (including a shared services center in El Salvador, corporate offices in Guatemala and Colombia, and a multinational corporation headquarters (SEM) in Panama, among others), digital transformation, customer experience, procurement, human resources, legal, information technology, marketing services and advisory services related to the construction, installation, operation, management and maintenance of its networks. If Millicom's central functions are unable to provide these services to our operating subsidiaries and joint ventures on a timely basis and at a level that meets our needs, our operating subsidiaries and joint ventures may be disrupted.

The majority of Millicom's operating subsidiaries and joint ventures operate under the Tigo trademark.

We take efforts to protect the Tigo trademark, but we may not always succeed in preventing others from using the trademark in countries in which we do not operate or from using similar trademarks, which could dilute the value of our trademark and result in brand confusion to consumers. The Tigo trademark could also be the subject of intellectual property infringement. Trademark protection is important because our trademark is what helps our customers differentiate our products and services from those of our competition, helps build brand loyalty, and represents our goodwill and reputation.

c.Talent acquisition and retention

We may be unable to obtain or retain adequate managerial and operational resources.

Our operating results depend, in significant part, upon the continued contributions and capacity of key senior management and technical personnel. Certain key employees possess substantial knowledge of our business and operations. We cannot assure you that we will be successful in retaining their services or that we would be successful in hiring and training suitable replacements without undue costs or delays. If we are unable to retain senior leadership to operate and grow our business, we may not be able to develop our business at the pace or with the required level of sophistication that enables us to meet our strategic and financial objectives.

Competition for personnel in our markets and certain central functions is intense due to scarcity of qualified individuals.

Millicom has been working with its local teams to build and implement talent development plans and to identify high-performance individuals for future advancement or hiring, as the markets in which we operate have limited availability of talent with advanced skill sets in key areas such as the digital and technology fields. We cannot assure you, however, that we will be successful in these efforts.

d.Financing and cash flow generation

MIC S.A. is a holding company and is dependent on cash flow from its operating subsidiaries and joint ventures.

MIC S.A.’s primary assets consist of shares in its subsidiaries and joint ventures and cash in its bank accounts. MIC S.A. has no significant revenue generating operations of its own, and therefore its cash flow and ability to service its indebtedness and pay dividends to its shareholders will depend primarily on the operating performance and financial condition of its subsidiaries and joint ventures and its receipt of funds in the form of dividends or otherwise.

There are legal limits on dividends that some of MIC S.A.’s subsidiaries and joint ventures are permitted to pay. Further, some of our indebtedness imposes restrictions on dividends and other restricted payments,

which are described under “Operating and Financial Review and Prospects—Liquidity and Capital Resources—Financing.”

Our ability to generate cash depends on many factors beyond our control, and we may need to resort to additional external financing.

Our ability to generate cash is dependent on our future operating and financial performance. This will be impacted by our ability to successfully implement our business strategy, as well as general economic, financial, competitive, regulatory, and technical elements and other factors beyond our control. If we cannot generate sufficient cash, we may, among other things, need to refinance all or a portion of our debt, obtain additional financing, delay capital expenditure or sell assets.

We require a significant amount of capital to operate and grow our business. We fund our capital needs in part through borrowings in the public and private credit markets. Adverse changes in the credit markets, including increases in interest rates, could increase our cost of borrowing and/or make it more difficult for us to obtain financing for our operations or refinance existing indebtedness. In addition, our borrowing costs can be affected by short- and long-term debt ratings assigned by independent rating agencies, which are based, in significant part, on our performance as measured by customary credit metrics. A decrease in these ratings would likely increase our cost of borrowing and/or make it more difficult for us to obtain financing. A severe disruption in the global financial markets could impact some of the financial institutions with which we do business, and such instability could also affect our access to financing.

In particular, periods of industry consolidation require businesses to raise debt and equity capital to remain competitive. An inability to access capital during such periods could have an adverse effect on our business, financial condition or results of operations.

The cash flow we generate is highly dependent on our operations in Guatemala.

Our operations in Guatemala have historically generated healthy cash flows. If the financial condition of our operations in Guatemala deteriorates, or if we fail to diversify our sources of cash flow, our liquidity could suffer, which could impact our capital allocation and limit our ability to reduce our leverage, reinvest in our business or remunerate our shareholders.

Our ability to pay dividends to our shareholders, consummate share repurchase programs or otherwise remunerate shareholders is subject to our distributable reserves and solvency requirements.

Any determination to pay dividends, adopt share repurchase programs or otherwise remunerate shareholders in the future will be at the discretion of our Board of Directors (as to interim dividends) and at the discretion of the shareholders at the annual general meeting (the "AGM") upon recommendation of the Board of Directors (as to annual dividends or share repurchases) and will depend upon our results of operations, financial condition, distributable reserves, contractual restrictions, restrictions imposed by applicable law and other factors our Board of Directors and the shareholders at the AGM, respectively, deem relevant.

We are not required to pay dividends on our shares or otherwise remunerate shareholders, and holders of our shares have no recourse if dividends are not declared. Our ability to pay dividends or otherwise remunerate shareholders may be further restricted by the terms of any of our existing and future debt or preferred securities. Additionally, because we are a holding company, our ability to pay dividends on our shares is limited by restrictions on the ability of our subsidiaries to pay dividends or make distributions to us, including restrictions on our ability to repatriate funds and under the terms of the agreements governing our indebtedness.

We have adopted, and may in the future adopt, share repurchase programs under which we are authorized to repurchase our shares. However, there can be no assurance that any future share repurchase program will be fully consummated. The amount, timing and execution of any share repurchase program may fluctuate based on our priorities for the use of cash or as a result of changes in cash flows, tax laws, and the market price of our shares. Any reduction or discontinuance by us of dividend payments or repurchases of our shares may cause the market price of our shares to decline.

4.Risks related to share ownership, governance practices and registration with the SEC

a.Share price, trading volume and market volatility

The price of our common shares might fluctuate significantly, and you could lose all or part of your investment.

Volatility in the market price of our common shares may prevent you from being able to sell our common shares at or above the price at which you purchased such shares. The trading price of our common shares has been and may in the future be volatile and subject to wide price fluctuations in response to various factors, including, among others: market conditions in the broader stock market in general, or in our industry in particular; actual or anticipated fluctuations in our financial and operating results; introduction of new products and services by us or our competitors; entry to new markets or exit from existing markets; issuance of new or changed securities analysts’ reports or recommendations, or the failure to receive industry analyst coverage; sales of large blocks of our shares; additions or departures of key personnel; regulatory developments; and litigation and governmental investigations or actions.

These and other factors may cause the market price and demand for our common shares to fluctuate substantially, which may limit or prevent investors from readily selling common shares and may otherwise negatively affect the liquidity of our common shares.

In addition, in the past, when the market price of a stock has been volatile, holders of that stock have often instituted securities class action litigation against the company that issued the stock. If any of our shareholders brought a lawsuit against us, we could incur substantial costs defending the lawsuit. Such a lawsuit could also divert the time and attention of our management from our business.

An active trading market for our common shares that will provide you with adequate liquidity may not develop.

Throughout 2024, a majority of the trading activity in our common shares comprised trading of our Swedish depository receipts that represent underlying common shares ("SDRs") listed on Nasdaq Stockholm. The Company's SDRs were delisted from Nasdaq Stockholm on March 17, 2025. As a result, the Company's common shares are only listed on the Nasdaq Global Select Market in the United States. We cannot predict if an active trading market will develop for our common shares on the Nasdaq Global Select Market or how liquid that market might become. If an active trading market does not develop for our common shares on the Nasdaq Global Select Market, you may have difficulty selling the common shares that you purchase, and the value of such shares might be materially impaired.

Future sales of our common shares, or the perception in the public markets that these sales may occur, may depress our share price, and future sales of our common shares may be dilutive.

Sales of substantial amounts of our common shares in the public market, or the perception that these sales could occur, could adversely affect the price of our common shares and could impair our ability to raise capital through the sale of shares. In the future, we may issue our shares, among other reasons, if we need to raise capital or in connection with merger or acquisition activity. The amount of our common shares issued in connection with a capital raise or acquisition could constitute a material portion of our then-outstanding share capital. Sales of shares in the future may be at prices below prevailing market prices, thereby having a dilutive impact on existing holders and depressing the trading price of our common shares.

b.Legal and regulatory compliance and burden

The obligations associated with being a public company in the United States require significant resources and management attention.

As a public company in the United States, we incur legal, accounting and other expenses that we did not previously incur. We are subject to the reporting requirements of the Exchange Act, the Sarbanes-Oxley Act, the listing requirements of the Nasdaq Stock Market and other applicable securities rules and regulations. The Exchange Act requires that we file annual and current reports with respect to our business, financial condition and results of operations. The Sarbanes-Oxley Act requires, among other things, that we establish and maintain effective internal controls and procedures for financial reporting.

Furthermore, the need to establish and maintain the corporate infrastructure demanded of a U.S. public company may divert management’s attention from implementing our strategy. We have made, and will continue to make, changes to our internal controls and procedures for financial reporting and accounting systems in order to meet our reporting obligations as a U.S. public company. However, the measures we take may not be sufficient to satisfy these obligations. In addition, compliance with these rules and regulations

has increased our legal and financial compliance costs and has made some activities more time-consuming. For example, these rules and regulations make it more expensive for us to obtain director and officer liability insurance.

In addition, changing laws, regulations and standards relating to corporate governance and public disclosure are creating uncertainty for U.S. public companies. These laws, regulations and standards are subject to varying interpretations, in many cases due to their lack of specificity, and, as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. This could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices. If our efforts to comply with new laws, regulations and standards differ from the activities intended by regulatory or governing bodies due to ambiguities related to their application and practice, regulatory authorities may initiate legal proceedings against us.

We are a foreign private issuer and, as a result, are not subject to U.S. proxy rules but are subject to Exchange Act reporting obligations that, to some extent, are more lenient and less frequent than those of a U.S. issuer.

We report under the Exchange Act as a non-U.S. company with “foreign private issuer” status, as such term is defined in Rule 3b-4 under the Exchange Act. Because we qualify as a foreign private issuer under the Exchange Act and although we follow Luxembourg laws and regulations with regard to such matters, we are exempt from certain provisions of the Exchange Act that are applicable to U.S. public companies, including:

(i)the sections of the Exchange Act regulating the solicitation of proxies, consents or authorizations in respect of a security registered under the Exchange Act;

(ii)the sections of the Exchange Act requiring insiders to file public reports of their stock ownership and trading activities and liability for insiders who profit from trades made in a short period of time; and

(iii)the rules under the Exchange Act requiring the filing with the SEC of quarterly reports on Form 10-Q containing unaudited financial and other specified information, or current reports on Form 8-K, upon the occurrence of specified significant events.

Foreign private issuers are required to file their annual report on Form 20-F by 120 days after the end of each fiscal year, while U.S. domestic issuers that are accelerated filers are required to file their annual report on Form 10-K within 75 days after the end of each fiscal year. Foreign private issuers are also exempt from the Regulation Fair Disclosure, aimed at preventing issuers from making selective disclosures of material information. As a result of the above, even though we are contractually obligated and intend to make interim reports available to our shareholders, copies of which we are required to furnish to the SEC on a Form 6-K, and even though we are required to file reports on Form 6-K disclosing whatever information we have made or are required to make public pursuant to Luxembourg law or distribute to our shareholders and that is material to our company, you may not have the same protections afforded to shareholders of companies that are not foreign private issuers.

If we fail to maintain an effective system of internal control over financial reporting, we may be unable to accurately report our financial results or prevent fraud, and investor confidence in our company and the market price of our shares may be adversely affected.

We are subject to reporting obligations under the U.S. securities laws. The SEC, as required by Section 404 of the Sarbanes-Oxley Act, adopted rules requiring every public company to include in its annual report a management report on such company’s internal control over financial reporting containing management’s assessment of the effectiveness of its internal control over financial reporting. In addition, an independent registered public accounting firm must attest to and report on the effectiveness of such company’s internal control over financial reporting except where the company is a non-accelerated filer. We currently are a large accelerated filer.

Our management has concluded that our internal control over financial reporting was effective as of December 31, 2024. See “Disclosure Controls and Procedures.” Our independent registered public accounting firm has issued a report as of December 31, 2024. See “Report of Independent Registered Public Accounting Firm on Internal Control over Financial Reporting.” However, if we fail to maintain an effective internal control over financial reporting in the future, our management and our independent registered public accounting firm may not be able to conclude that we have effective internal control over financial reporting in accordance with Section 404 of the Sarbanes-Oxley Act. If we fail to achieve and maintain an effective internal control environment, we could suffer material misstatements in our consolidated financial

statements and fail to meet our reporting obligations, which would likely cause investors to lose confidence in our reported financial information. This could in turn limit our access to capital markets, harm our results of operations, and lead to a decline in the trading price of our shares. Additionally, ineffective internal control over financial reporting could expose us to increased risk of fraud or misuse of corporate assets and subject us to potential delisting from the stock exchange on which we list, regulatory investigations and civil or criminal sanctions.

We may lose our foreign private issuer status in the future, which could result in significant additional costs and expenses.

As a foreign private issuer, we are not required to comply with the same periodic disclosure and current reporting requirements of the Exchange Act, and related rules and regulations, that apply to U.S. domestic issuers. Under Rule 3b-4 of the Exchange Act, the determination of foreign private issuer status is made annually on the last business day of an issuer’s most recently completed second fiscal quarter and, accordingly, we will make the next determination with respect to our foreign private issuer status based on information as of June 30, 2025.

In the future, we could lose our foreign private issuer status if, for example, a majority of our voting power were held by U.S. citizens or residents and we fail to meet additional requirements necessary to avoid loss of foreign private issuer status. The regulatory and compliance costs to us under U.S. securities laws as a domestic issuer may be significantly higher.

If we are not a foreign private issuer, we will be required to file periodic reports and registration statements on U.S. domestic issuer forms with the SEC, which are more detailed and extensive than the forms available to a foreign private issuer. We will also be required to comply with U.S. federal proxy requirements, and our officers, directors and controlling shareholders will become subject to the short-swing profit disclosure and recovery provisions of Section 16 of the Exchange Act. We may also be required to modify certain of our policies to comply with good governance practices associated with U.S. domestic issuers. Such conversion and modifications will involve additional costs. In addition, we may lose our ability to rely upon exemptions from certain corporate governance requirements on U.S. stock exchanges that are available to foreign private issuers.

c.Shareholder protection

Xavier Niel owns a significant amount of Millicom’s shares, giving him substantial management influence that may not align with the interests of our other shareholders.

As of December 31, 2024, Atlas S.A.S., formerly known as Atlas Luxco S.à r.l. (“Atlas”), owned 69,236,111 shares, representing 40.37% of the voting shares of the Company. The sole owner of Atlas is Atlas Investissement S.A.S., and the sole owner of Atlas Investissement S.A.S. is Iliad Holding S.A.S., which is owned by Xavier Niel and his children. In addition, three of our eight directors are affiliated with Mr. Niel.

As a result, Mr. Niel has the ability to exert significant influence over our strategic, operating and financial policies. Mr. Niel also has the ability to influence the election of our directors and the outcome of other corporate actions requiring shareholder approval, such as a merger or sale of the Company, a sale of all or substantially all of our assets, or amendments to our Articles of Association. This concentration of voting power could have a significant effect in delaying, deferring or preventing an action that might otherwise be beneficial to our other shareholders or that could be disadvantageous to our shareholders with interests different from those of Mr. Niel. In addition, the significant concentration of ownership may adversely affect the market value of our common shares due to investors’ perception that conflicts of interest may exist or arise.

Although we are not considered to be a “controlled company” under Nasdaq corporate governance rules, we could in the future become a controlled company if Atlas were to acquire more than 50% of the voting power of the Company. If this were to occur, we may in the future elect to rely on the “controlled company” exemptions under the Nasdaq corporate governance rules, particularly in the event that we no longer qualify as a foreign private issuer and therefore cease to be eligible for the exemptions separately provided by such status. In that event, our shareholders would not have the same protection afforded to shareholders of companies that are subject to all of the Nasdaq corporate governance standards.

MIC S.A. is incorporated in Luxembourg, and Luxembourg law differs from U.S. law and may afford less protection to holders of our shares.

The Company is incorporated under and subject to Luxembourg laws. Luxembourg laws may differ in some material respects from laws generally applicable to U.S. corporations and shareholders, including the provisions relating to interested directors, mergers, sales, amalgamations and acquisitions, takeovers, shareholder lawsuits and indemnification of directors. Luxembourg laws governing the shares of Luxembourg companies may not be as extensive as those in effect in the United States, and Luxembourg law and regulations in respect of corporate governance matters might not be as protective of shareholders as state corporation laws in the United States. Therefore, our shareholders may have more difficulty in protecting their interests in connection with actions taken by our directors and officers or our principal shareholders than they would as shareholders of a corporation incorporated in the United States. For example, neither our articles of association, as amended and restated (the "Articles of Association") nor Luxembourg law provides for appraisal rights for dissenting shareholders in certain extraordinary corporate transactions that may otherwise be available to shareholders under certain U.S. state laws.

In addition, under Luxembourg law, by contrast to the laws generally applicable to U.S. corporations, the duties of directors of a company are in principle owed to the company only, rather than to its shareholders. It is possible that a company may have interests that are different from the interests of its shareholders. Shareholders of Luxembourg companies generally do not have rights to take action themselves against directors or officers of the company. Directors or officers of a Luxembourg company must, in exercising their powers and performing their duties, act in good faith and in the interests of the company as a whole and must exercise due care, skill and diligence.

Directors have a duty to disclose any personal interest in any contract or arrangement with the company in case such interest would constitute a conflict of interest. If any director has a direct or indirect financial interest in a matter which has to be considered by the Board of Directors which conflicts with the interests of the company, Luxembourg law provides that such director will not be entitled to take part in the relevant deliberations or exercise his or her vote with respect to the approval of such transaction. If the interest of such director does not conflict with the interests of the company, then the applicable director with such interest may participate in deliberations on, and vote on the approval of, that transaction. If a director of a Luxembourg company is found to have breached his or her duties to that company, he or she may be held personally liable to the company in respect of that breach of duty. A director may, in addition, be jointly and severally liable with other directors implicated in the same breach of duty.

The ability of investors to enforce civil liabilities under U.S. securities laws may be limited.

MIC S.A. is a Luxembourg public limited liability company (société anonyme) and some of its directors and executive officers are residents of countries other than the United States. Most of the Company’s assets and the assets of some of its directors and executive officers are located outside the United States. As a result, it may not be possible for investors in our securities to effect service of process within the United States upon such persons or the Company or to enforce in U.S. courts or outside the United States judgments obtained against such persons or the Company. In addition, it may be difficult for investors to enforce, in original actions brought in courts in jurisdictions located outside the United States, liabilities predicated upon the civil liability provisions of U.S. securities laws.

We have been advised by our Luxembourg counsel, Hogan Lovells (Luxembourg) LLP that the United States and Luxembourg do not have a treaty providing for reciprocal recognition and enforcement of judgments in civil and commercial matters. Therefore, a judgment for the payment of money rendered by a U.S. federal or state court will only be recognized and enforced against MIC S.A. by a court in Luxembourg without re-examination of the merits of the case if (i) it is a final judgment which is not subject to appeal or any other means of contestation and (ii) it complies with the applicable enforcement procedure (exequatur) conditions, as set out in the relevant provisions of the Luxembourg New Code of Civil Procedure (Nouveau Code de Procédure Civile) and Luxembourg case law.

As a foreign private issuer and as permitted by the listing requirements of the Nasdaq, we may rely on certain home country governance practices rather than the Nasdaq corporate governance requirements.

As a foreign private issuer and in accordance with Nasdaq Listing Rule 5615(a)(3), we may comply with home country governance requirements and certain exemptions thereunder rather than complying with certain of the corporate governance requirements of Nasdaq. For example, Luxembourg law does not require that a majority of our Board of Directors consists of independent directors. While we currently have a Board of Directors that is independent of the Company (i.e., the board members are not members of management or

employees of the Company), our Board of Directors may in the future include fewer independent directors than would be required if we were subject to Nasdaq Listing Rule 5605(b)(1). For more information on our reliance on certain home country practices and how they deviate from Nasdaq rules, see "Corporate Governance—Corporate Governance Statement and Framework."

Risk Management

Risks and Uncertainty

Millicom operates its business in emerging markets with unpredictable political and economic environments, presenting a higher level of inherent risk compared to mobile and cable businesses in more mature markets. Our governance and oversight structure is designed to reduce uncertainties and mitigate these risks. Thus, we only accept risks in our businesses and markets to the extent that opportunities for sufficient returns exist, and where we can design, implement, and operate appropriate systems and controls to manage those risks.

We recognize that risk is linked with opportunity and closely aligned with strategic goals. Our risk management focus is on reducing uncertainty to enhance decision-making in strategy formulation and the allocation of capital and resources.

Risk Management

The Board of Directors is responsible for ensuring a sound system of risk management and internal controls and overseeing the processes that govern the identification, assessment, and prioritization of risks. The Audit and Compliance Committee reviews risk management reports and the methodology and controls within the organization.

Responsibility for maintaining effective internal controls is delegated to the CEO and the Group Leadership Team with oversight provided by the Audit and Compliance Committee. The Group Leadership Team is supported by a dedicated Business Control team responsible for the internal control framework. Each country also has its own dedicated local Business Control team responsible for monitoring and development of the local internal control environment.

Risks are identified and managed by management. We prioritize risks based on likelihood of occurrence and importance to the business. We quantify, measure, and monitor risks using risk indicators, with action plans to reduce gaps between current and target risk levels. Millicom has a management risk committee comprised of members of the Group Leadership Team and central functions responsible for key enterprise risks (the "Management Risk Committee"). The Management Risk Committee meets at least quarterly to consider the evolution of key risks, monitor risk levels against appetite and tolerance, and consider future potential uncertainties and how they may manifest themselves as risks to Millicom's business. The Chief Risk Officer is part of the Group Leadership Team.

The Internal Audit & Enterprise Risk Management function is responsible for the design, implementation, and monitoring of Millicom’s enterprise risk management framework and processes.

Technology and Information

Information Security

Our Global Chief Information Security Officer ("CISO") manages the information security program and reports to the Chief Technology and Information Officer ("CTIO"). The CISO is responsible for identifying, managing and mitigating technology-centric risks throughout the Company. The CISO oversees regional information security teams to ensure the confidentiality, integrity and availability of all business-critical information systems and assets, and the regional information security teams work closely with business and technology leaders to ensure compliance with corporate policies and regional information security regulatory requirements within the various countries where we conduct business.

In early 2024, the CISO and CTIO departed the Company. In July 2024, Guillaume Duhaze assumed the role of CTIO, and Lourdes Lay Sánchez, the Company's Information Security Director, assumed the responsibilities of the CISO (the "CISO").

Cybersecurity Risk Management

Cybersecurity risk management is an integral part of our overall enterprise risk management. We manage cybersecurity risks through our information security program, which is designed to align with the National Institute of Standards and Technology Cybersecurity Framework ("NIST CSF"). Our information security program manages cybersecurity risks by creating a framework for identifying the source of cybersecurity threats and incidents (including threats associated with the use of services provided by third-party service providers), training employees and specialized roles, implementing measures to protect critical data and data flows, monitoring essential networks and applications, identifying and remediating vulnerabilities and informing executive management and our Board of Directors of material cybersecurity threats and incidents.

Our cybersecurity team also engages a third-party consultant for risk incident detection and vulnerability assessment, which employs a risk management program based on Rapid7's solutions. We confer with our third-party consultant on a weekly basis to assess the adequacy and strength of our monitoring efforts, address operational issues and drive continuous improvement.

In 2024, we did not identify any cybersecurity threats that have materially affected or are reasonably likely to materially affect our business strategy, results of operations or financial condition. However, despite our efforts, we cannot eliminate all risks from cybersecurity threats, or provide assurances that we have not experienced an undetected cybersecurity incident. For more information about these risks, please see "Key Information—1. Risks related to the telecommunications, cable and MFS industries—f. Cybersecurity and data protection" in this Annual Report.

Cybersecurity Risk Governance

Role of the Board of Directors

Our Board of Directors has overall oversight responsibility for our risk management and delegates cybersecurity risk management oversight to the Audit and Compliance Committee of the Board of Directors. The Audit and Compliance Committee is responsible for ensuring that management has processes in place that are designed to mitigate cybersecurity risks to an acceptable level, in line with the Company's risk appetite and risk tolerance, and to:

•monitor the Company’s information security program, including the activities performed by the information security team;

•provide oversight and direction on information security risk management, including cybersecurity and related threats;

•ensure that the Company allocates the proper level of resources to information security and cybersecurity;

•monitor results and remediation of findings from audit and assurance activities related to the Company’s information security program; and

•ensure that material information security and cybersecurity issues affecting the Company’s internal control environment are communicated to the Audit and Compliance Committee of the Company.

Role of Management

While our Board of Directors has overall responsibility for the oversight of our enterprise risk management, our management is responsible for day-to-day risk management. Our cybersecurity risk management is under the direction of our CTIO and CISO, and they are primarily responsible for defining and implementing our information security program and cybersecurity risk management (which we do not engage third parties for). In particular, our CTIO and CISO are responsible for identifying, considering and assessing material cybersecurity risks on an ongoing basis, establishing processes and risk indicators to ensure that such potential cybersecurity risk exposures are monitored, and implementing mitigating actions and plans to lower risks to targeted levels. In addition, our CTIO and CISO oversee the design of trainings on cybersecurity risks that are provided to all employees at least annually, with specialized trainings for executives, developers, system, network and database administrators and other key roles within the Company. More than 90% of our employees participated in security awareness and training in 2024 covering key threats—including but not limited to phishing risk—as well as prevention and company procedures.

Our CTIO and CISO receive reports from our cybersecurity team and monitor the prevention, detection, mitigation and remediation of cybersecurity incidents. Under the cybersecurity incident response plan, our CISO assigns a severity rating to each incident, and an escalation matrix is used to provide notifications to management and the Board of Directors based on the severity and duration of the incident.

In addition, our CTIO and CISO provide a quarterly update to the Audit and Compliance Committee on Millicom's cybersecurity risk management that includes reports on cybersecurity threats and incidents, mitigation strategies and

remediation plans, recent developments in cybersecurity and updates to the Company's cybersecurity programs. Our CTIO and CISO provide a similar cybersecurity update to management, typically once a month.

Our CTIO and CISO are experienced information systems security professionals. Our CTIO has more than 30 years of experience in the telecommunications industry, particularly with technology-related aspects of telecommunication companies. His presence in the telecommunications business makes him knowledgeable about the technology and cybersecurity risks that are specific to the industry and our markets. Our CISO has over 20 years of experience in information technology, including 15 years in information technology security, information security, and managing cybersecurity risks, and is certified in cybersecurity by the Information System Security Certification Consortium (ISC2).

Business Overview

Introduction

We are a leading provider of fixed and mobile services dedicated to emerging markets. Through our main brands Tigo® and Tigo Business™, we provide a wide range of digital services in nine countries in Latin America, including high-speed data, cable TV, direct-to-home satellite TV (“DTH” and when we refer to DTH together with cable TV, we use the term “pay-TV”), mobile voice, mobile data, SMS, MFS, fixed voice, and business solutions including value-added services (“VAS”). We provide services on both a business-to-consumer (“B2C”) and a business-to-business (“B2B”) basis, and we have used the Tigo brand in all our markets since 2004.

We offer the following principal categories of services:

•Mobile, including mobile data, mobile voice, and MFS to consumer, business and government customers;

•Fixed and other services, including broadband, pay-TV, content, and fixed voice services for residential (Home) customers, as well as voice, data and VAS and solutions to business and government customers.

We provide both mobile and cable services in eight countries: Bolivia, Colombia, El Salvador, Guatemala, Honduras, Nicaragua, Panama and Paraguay. In addition, we provide cable services in Costa Rica. We previously provided mobile services including mobile financial services in Africa, which we finally exited in April 2022 when we disposed of our operations in Tanzania to focus on the Latin American region.

Additionally, we have a large portfolio of infrastructure across Latin America and, including our Honduras joint venture, our portfolio includes more than 9,300 towers, 12 Tier III data centers and more than 200,000 kilometers of fiber. In 2023, we created a new wholly owned tower infrastructure company, Lati International S.A. ("Lati"), and in 2024 we announced an agreement to sell Lati, including a portfolio of more than 7,000 towers in Central America, to SBA Telecommunications LLC. See note A.1. to our audited consolidated financial statements included elsewhere in this Annual Report.

During the latter half of 2023 and throughout 2024, Millicom implemented significant organizational changes to focus on driving profitable growth with a leaner corporate structure. The Group streamlined its structure, with all General Managers of operations and Group Leadership Team members reporting directly to the Chief Executive Officer ("CEO"). The CEO, together with the Chief Financial Officer ("CFO") and the Chief Technology & Information Officer ("CTIO"), form the Chief Operating Decision Maker (“CODM”). Following these organizational changes, and considering the information being reviewed by the CODM to assess performance and allocate resources, Millicom's operating segments were redefined to align with its countries of operation. Our reportable segments consist of Guatemala, Colombia, Panama, Bolivia, Honduras, Paraguay, and Other, which includes Nicaragua, Costa Rica and El Salvador. See “Operating and Financial Review and Prospects—Operating Results—Our segments.”

We conduct our operations through local holding and operating entities in various countries, which are either our subsidiaries (in which we are the sole shareholder or the controlling shareholder) or joint ventures with local partners. For further details, see note A. to our audited consolidated financial statements. In this Annual Report, our description of our operations includes the operations of all of these subsidiaries and joint ventures.

As of December 31, 2024, we provided services to 41.5 million mobile customers and 4.5 million customer relationships with a subscription to at least one of our fixed services. This includes 4.0 million customer relationships on our HFC and FTTH networks and 0.4 million DTH subscribers. The remaining customer relationships are served using various technologies, including fixed wireless solutions as well as our legacy copper network. We also provide mobile financial services ("MFS") under our Tigo Money brand, which operates in Paraguay, Guatemala, El Salvador, Bolivia and Honduras.

For the year ended December 31, 2024, our revenue was $5,804 million and our net income attributable to the owners of the company was $253 million. We had approximately 14,000 employees, including our Honduras joint venture.

Our strategy

Our strategy is to continue to expand the reach and capacity of our networks and distribution capabilities to grow our customer base over time. Underpinning this strategy is management’s assessment that penetration rates for both mobile and fixed broadband services in our markets are low relative to penetration rates in other markets globally, and

that they have potential to increase over time. Based on our own subscriber data, mobile broadband penetration rates, as measured by the number of subscribers who use a smartphone to access mobile data services on 4G networks, were approximately 73% in Bolivia, 66% in Colombia, 60% in Paraguay, 58% in Panama, 58% in Honduras, 55% in El Salvador, 52% in Nicaragua and 40% in Guatemala as of December 31, 2024. Based on our own customer data and market intelligence, fixed and other services penetration rates, as measured by the number of residential broadband customers as a percentage of households in the country, were approximately 58% in Costa Rica, 58% in Colombia, 48% in Panama, 43% in Paraguay, 40% in El Salvador, 33% in Bolivia, 27% in Guatemala, 23% in Honduras, and 21% in Nicaragua as of December 31, 2024. Pay-TV penetration rates, as measured by the number of pay-TV customers, including DTH, as a percentage of households in the country, were approximately 49% in Costa Rica, 42% in Panama, 38% in Colombia, 36% in Paraguay, 35% in El Salvador, 31% in Guatemala, 24% in Honduras, 17% in Nicaragua, and 15% in Bolivia as of December 31, 2024.

Our services

Our services are organized into two principal categories: (1) Mobile and (2) Fixed and other services. In addition, we sell telephone and other equipment, comprised mostly of mobile handsets. We market these services through a variety of channels, including owned and third-party retail outlets, direct sales, digital and internet advertising, television, and billboards, among others.

Mobile

In our Mobile category, we provide mobile services, including mobile data, mobile voice, SMS and MFS, to consumers, businesses, and government customers.

Mobile is the largest part of our business and generated 58% of consolidated service revenue for the year ended December 31, 2024 and 57% of our consolidated service revenue for the year ended December 31, 2023.

Mobile data, mobile voice and SMS

We provide our mobile data, mobile voice and SMS services through 2G, 3G and 4G networks in all our mobile markets, and we have offered 5G in Guatemala since 2022.

We provide our mobile data, mobile voice and SMS services on both prepaid and postpaid bases. In prepaid, customers pay for service in advance through the purchase of limited-duration data packages, and they do not sign service contracts. Among various options that our customers can choose from, we offer packages that typically begin with a data allowance, and include a combination of voice minutes and SMS, with expiration dates varying in length from one or more days, up to a few weeks or months. In postpaid, customers pay recurring monthly fees for the right to consume up to a predetermined maximum amount of monthly data, voice usage and SMS.

Mobile Financial Services (MFS)

We provide a broad range of mobile financial services ("MFS") such as payments, money transfers, international remittances, savings, real-time loans and micro-insurance for critical needs through our MFS App, Tigo Money. Tigo Money allows our customers to send and receive money, without the need for a bank account. As of December 31, 2024, we provided MFS to 3.7 million Tigo and non-Tigo customers. The service complements our Mobile and Fixed service offerings and increases customer satisfaction and loyalty, increasing ARPU and reducing customer churn. Since 2022, we have been exploring entering into new financial and strategic partnerships aimed at enhancing Tigo Money's value creation potential and enabling a partial or full divestiture of Tigo Money in the future.

Fixed and other service revenue

In our Fixed and other service revenue category, we provide fixed services, including broadband, fixed voice and pay-TV, to residential (Home) consumers and to government and business (B2B) customers. Fixed and other service revenue generated 40% of our consolidated service revenue for the year ended December 31, 2024 and 42% of our consolidated service revenue for the year ended December 31, 2023.

Home

Our fixed-service residential customers (a “customer relationship”) generate revenue for us by purchasing one or more of our three fixed services: pay-TV, fixed broadband, and fixed telephony. We refer to each service that a customer purchases as a revenue generating unit (“RGU”), such that a single customer relationship can have up to three RGUs in countries where we are permitted to sell all three services.

We provide Home services mainly over our HFC and FTTH networks, but we also offer pay-TV services via our DTH platform. In some markets, we also provide broadband services using fixed-wireless access and copper-based technologies. Throughout this report, we include FTTH network and customer metrics as a subset of our HFC network and customer metrics.

We provide Home services in every country where we operate. As of December 31, 2024, the Group had 4.5 million customer relationships, of which 4.0 million were connected to our HFC and FTTH networks, and we had 8.1 million HFC and FTTH RGUs.

B2B fixed

We offer fixed-voice and data telecommunications services, managed services and cloud and security solutions to small, medium and large businesses and governmental entities. We offer B2B fixed services in all of the markets in which we operate.

We have already deployed more than 200,000 kilometers of fiber in our markets, including our Honduras joint venture, and we are expanding our product portfolio to deliver more VAS and business solutions, such as cloud-based services and ICT managed services. We have also established partnerships in the area of hypercloud, virtualization and Internet of Things, to capture the growth in the adoption of these technologies and help our customers accelerate their digital transformations.

Our markets

Overview

The nine markets we serve are Bolivia, Colombia, Costa Rica, El Salvador, Guatemala, Honduras (through our joint venture), Nicaragua, Panama and Paraguay. We provide Fixed and other services in each of these markets, and we provide Mobile services in each market except for Costa Rica.

The following chart shows the relative revenue generation of each country in our Group for 2024 (excluding our Honduras joint venture and before inter-segment and other eliminations):

We have operated in Costa Rica since our acquisition of Amnet in 2008. Amnet and its predecessor companies began operating in Costa Rica in 1982, and the company was the first to provide pay-TV services in the country. As further disclosed in our audited consolidated financial statements included elsewhere in this Annual Report, on August 1, 2024, we signed a binding agreement with Liberty Latin America to combine our operations in Costa Rica in a cashless merger in which Millicom would retain a minority equity ownership of approximately 14%. The transaction is subject to closing conditions, including regulatory approvals, and is expected to close during the second half of 2025.

Fixed and other services: As of December 31, 2024, we had 218,000 customer relationships through our HFC network and DTH services, and we were the second largest provider of pay-TV and the fourth largest provider of broadband internet services in Costa Rica, as measured by subscribers.

We continue to invest to expand and upgrade the capacity of our fixed network in Honduras.

Nicaragua

In 2019, we purchased Telefonía Celular de Nicaragua, S.A., the leading provider of Mobile services in the country, based on the number of subscribers. As of December 31, 2024, we served 3.7 million mobile subscribers.

Prior to 2019, we had a very small presence in Nicaragua, where we provided mostly B2B fixed services. We have also provided Cable services to a small but rapidly growing customer base since 2018. We were the third largest provider of pay-TV and second largest provider of broadband services, as measured by subscribers, as of December 31, 2024.

Panama

We provide Mobile and Fixed and other services in Panama through Telecomunicaciones Digitales, S.A., formerly known as Cable Onda S.A. ("Tigo Panama"). We have operated in Panama since our acquisition of an 80% stake in Tigo Panama in December 2018. In June 2022, we acquired the remaining 20% stake and now own 100% of Tigo Panama. Tigo Panama and its predecessor companies began operating in 1982, and the Company was the first to provide pay-TV services in the country. In 2019, Tigo Panama acquired Grupo de Comunicaciones Digitales S.A. (formerly Telefónica Móviles Panamá, S.A.) and started to provide Mobile services.

Fixed and other services: We are the largest provider of pay-TV and broadband internet services in Paraguay as measured by subscribers. As of December 31, 2024, we had 481,000 customer relationships with our fixed networks, DTH, and, to a much lesser extent, other technologies. We offer pay-TV services primarily using our fixed network, and we use our DTH license to offer pay-TV in areas not reached by our fixed network. We offer residential broadband internet services mostly using our fixed network, but we also employ wireless technology to provide service beyond the reach of our fixed networks. We have exclusive rights to broadcast Paraguay’s national league championship games through 2027, and we have exclusive sponsorship rights in telecommunications for the Paraguayan National Soccer Team through 2026.

Regulation

The licensing, construction, ownership and operation of cable TV and mobile telecommunications networks and the grant, maintenance and renewal of cable TV and mobile telecommunications licenses, as well as radio frequency allocations and interconnection arrangements, are regulated by different governmental authorities in each of the markets that Millicom serves. The regulatory regimes in the markets in which Millicom operates are less developed than in other countries such as the United States and countries in the European Union, and can therefore change quickly. See “Key Information—Risk Factors—2. Risks related to Millicom's business in the markets in which it operates—F. Legal and regulatory—Developing legal systems in the countries in which we operate create a number of uncertainties for our businesses.”

Typically, Millicom’s cable and mobile operations are regulated by the government (e.g., a ministry of communications), an independent regulatory body or a combination of both. In all of the markets in which Millicom operates, there are ongoing discussions and consultation processes involving other operators and the governing authorities regarding issues such as mobile termination rates and other interconnection rates, universal service obligations, interconnection obligations, spectrum allocations, universal service funds and other industry levies and number portability. This list is not exhaustive; such ongoing discussions are a typical part of operating in a regulated environment.

Changes in regulation can sometimes impose new burdens on the telecommunications industry and have a material impact on our business and on our financial results. For example, regulators in our markets periodically require that we reduce the interconnection fees that we charge other telecom operators to terminate voice traffic on our network. At times, such measures can have a material adverse effect on our overall results of operations. For example, in response to public health crises, governments in several of our markets have prohibited, and may again prohibit, the disconnection of customers with past due accounts for an extended period, which impacted our revenues and collections.

The mobile services we provide require the use of spectrum, for which we have various licenses in each country where we provide mobile services. Spectrum licenses have expiration dates that typically range from 10 to 20 years. Historically, we have been able to renew our licenses upon expiration by agreeing to pay additional fees. We generally expect to continue to renew most of our current licenses as they expire, and we expect to acquire new spectrum licenses as they become available in the future.

Below, we provide further regulatory details in respect of certain of our countries of operation.

Bolivia: We hold a license to provide telecommunication services in Bolivia until 2051, mobile service authorization and spectrum licenses until 2028/2031, cable, VOIP authorizations until 2028 and internet authorizations until 2046.

Colombia: Colombia Móvil S.A. (Colombia Móvil) holds two separate nationwide spectrum licenses in the 1900 MHz band totaling 50 MHz, the earliest of which expires in 2029. The renewal of the AWS license was approved until December 2025. As further disclosed in Note E.4.2. to our audited consolidated financial statements, on February 26, 2024, Tigo Colombia and Coltel signed an agreement to share their mobile networks. In December 2024, the Ministry of Information Technologies and Communications approved the transfer of a 20 MHz license in the 700 MHz band to the Colombia Móvil - Colombia Telecomunicaciones joint operation and additionally, the Colombia Móvil - Colombia Telecomunicaciones joint operation was awarded 80 MHz of spectrum until 2044.

Costa Rica: We hold a general license to provide telecommunication services which expires in 2029, and a spectrum permit to download content for cable TV services which expires in 2029.

El Salvador: We hold a license to provide TV services until 2029 (fixed), telephone services until 2030, wireless telephone services until 2034 and several spectrum licenses until 2041.

Guatemala: We operate a nationwide mobile network and hold spectrum licenses with the earliest expiration in 2026.

Honduras: Celtel has spectrum licenses in the 850 MHz and AWS bands, which expire in 2028. The Honduran government has been planning a multi-band frequency spectrum auction in the 700 MHz and 3,500 MHz bands. However, any spectrum auction is expected to be executed after a modification of the applicable telecommunications law.

Panama: We hold cable TV, radio licenses and certain licenses to operate local, national and international long distance telephony and resale services that will expire in 2044. We also have certain other licenses to operate national and international long-distance telephony, which we expect to renew. A new block of 2x5 MHz in the 700 MHz band was assigned until 2036, totaling 30 MHz in the band.

Paraguay: We own licenses in four bands of spectrum in Paraguay with the earliest expiration in 2026. We also hold an internet access and data transmission license that will expire in 2029.

Trademarks and licenses

We own or have rights to some registered trademarks in our business, including Tigo®, Tigo Business®, Tigo Sports®, Mi Tigo®, Tigo Shop®, Tigo Money®, Tigo OneTv ®, Millicom® and The Digital Lifestyle®, among others. Under a number of trademark license agreements and letters of consent, certain operating subsidiaries are authorized to use the Tigo and Millicom trademarks under the applicable terms and conditions.

Research and Development, Patents and Licenses, etc.

We do not engage in research and development activities, and we do not own any patents.

Property, Plant and Equipment

Overview

We own, or have the right to access and use through long-term leases, telecommunications sites and related infrastructure and equipment in all of our markets. In addition, we own, or have the right to access and use through long-term leases, tower space, warehouses, office buildings and related telecommunications facilities in all of our markets. We are also party to several site sharing agreements whereby we share our owned telecommunications sites and related infrastructure and equipment, or lease such property from our counterparties in an effort to maximize the use of telecommunications sites globally. Our leased properties are owned by private individuals, corporations and sovereign states.

Assets used for the provision of cable TV and mobile telephone services include, without limitation:

• switching, transmission and receiving equipment;

• connecting lines (cables, wires, poles and other support structures, conduits and similar items);

• diesel generator sets and air conditioners;

• real property and infrastructure, including telecommunications towers, office buildings and warehouses;

• easements and other rights to use or access real property;

• access roads; and

• other miscellaneous assets (work equipment, furniture, etc.).

Tower infrastructure

We determined that owning passive infrastructure, such as mobile telecommunications towers, no longer confers a competitive advantage in our markets and that utilization of these assets could be optimized.

As a result, in 2023, we created Lati International S.A. and began the process of identifying and transferring towers to newly created local legal entities in each of our countries of operation in order to operate and manage these assets separately in the future.

In order to optimize the capital structure of our Towers business, we have also initiated a monetization process. We believe this will allow us to focus our capital investment on other fixed assets, such as network equipment, thereby increasing our network coverage, capacity and the overall quality of our service, while also improving our return on invested capital. On October 28, 2024, we agreed to sell certain Lati assets, encompassing a portfolio of more than 7,000 towers in Central America, to SBA Telecommunications LLC. Closing is subject to regulatory approvals and other closing conditions and is expected to occur in mid-2025. Following the sale, Millicom will continue to own certain Lati subsidiaries in Bolivia and Paraguay that own and operate approximately 2,300 towers.

Tower sales in Colombia

On January 24, 2024, Tigo Colombia signed an agreement to sell and lease back, under a long-term lease agreement, 1,132 telecommunication towers to Towernex Colombia S.A.S. (“Towernex”), a KKR company. The total sale consideration amounts to $77 million, of which $26 million will be received in subsequent years. Under IFRS 16, this transaction is considered a sale and leaseback. Cash from the sale is presented as a cash inflow from investing activity in the statement of cash flows to our audited consolidated financial statements.

For additional information, see note E.4. to our audited consolidated financial statements included elsewhere in this Annual Report.

Organizational Structure and Subsidiaries

The parent company, Millicom International Cellular S.A. ("MIC S.A."), is a Luxembourg public limited liability company (société anonyme). The following table identifies MIC S.A.’s main subsidiaries as of December 31, 2024:

Telemovil El Salvador S.A. de C.V.	El Salvador	Mobile, Cable, DTH	100
UNE EPM Telecomunicaciones S.A. and subsidiaries	Colombia	Fixed-line, Internet, Pay-TV, Mobile	50-1 share
* Also reflects the voting interest, except in Colombia where voting interest is 50% + 1 share for each of the two entities.
(i) Lati International S.A. is the holding company of our tower business.
(ii) Millicom International Operations B.V. was held by Millicom Holding B.V. and MIC Latin America B.V. until they merged in July 2024.
(iii) Millicom Telecommunications S.A. is the holding company of most of our MFS business.
(iv) Servicios y Productos Multimedios S.A. merged with Telefónica Celular del Paraguay S.A. in April 2024.

In addition, we provide services in Honduras through Celtel, a joint venture in which MIC S.A. indirectly holds a 66.67% equity interest. We entered into our joint venture in Honduras at the inception of this business in the 1990s. At that time, Millicom had limited sources of capital and was investing heavily to deploy mobile operations in many countries around the world; this partner provided local market expertise and reduced Millicom’s overall capital needs. Despite the fact that Millicom owns more than 50% of the shares of this entity and has the right to nominate a majority of the directors, all decisions taken by the board or the shareholders in Honduras must be taken by a supermajority vote. This effectively gives either shareholder the ability to veto any decision and therefore neither shareholder has sole control over our joint venture in Honduras.

OPERATING AND FINANCIAL REVIEW AND PROSPECTS

The following discussion of our financial condition and results of operations should be read in conjunction with our audited consolidated financial statements for the years ended December 31, 2024, 2023 and 2022, and the notes thereto, included elsewhere in this Annual Report.

The following discussion contains forward-looking statements that involve risks and uncertainties. Our actual results and the timing of events may differ materially from those expressed or implied in such forward-looking statements as a result of various factors, including those set forth in “Forward-Looking Statements” and “Key Information—Risk Factors.”

Operating Results

Factors affecting our results of operations

Our performance and results of operations have been and will continue to be affected by a number of factors and trends, including principally:

• Macro and socio-demographic factors. These affect demand for and affordability of our services and include consumer confidence and expansion of the middle class, as well as foreign currency exchange rate volatility and inflation which can impact our cost structure and profitability. Growth in GDP per capita and expansion of the middle class make our services affordable to a larger pool of consumers. The emerging markets we serve tend to have younger populations and faster household formation, and typically have more children per family, than developed markets, driving demand for our residential services, such as broadband internet and pay-TV. Digitalization of societies leads to more devices connected per household and more data needs. Exposure to inflationary pressures and foreign currency exchange volatility may negatively impact our profitability or make our services more expensive for our customers. See “Quantitative and Qualitative Disclosures About Market Risk—Foreign currency risk.”

• Competitive intensity, which largely reflects the number of market participants and the financial strength of each, varies over time and from market to market. Markets tend to be more price competitive and less profitable for us when there are more market participants, and thus any future increase in the number of market participants in any of our markets would likely have a negative effect on our business.

• Changes in regulation. Our business is highly dependent on a variety of licenses granted by regulators in the countries where we operate. Any changes in how regulators award and renew these licenses could impact our business. In particular, our mobile services business requires access to licensed spectrum, and we expect our business and the mobile industry in general to require more spectrum in the future to meet future mobile data traffic needs. In addition, regulators can impose certain constraints and obligations that can have an impact on how we operate the business and on our profitability.

• Technological change. Our business relies on technology that continues to evolve rapidly, forcing us to adapt and deploy new innovations that can impact our investment needs and our cost structure, as well as create new revenue opportunities for both our mobile and fixed services. With respect to mobile services, the global industry is already well advanced in the deployment of 5G, which we expect will drive continued demand for data in the future. With respect to fixed services, the cable infrastructure we are deploying, largely based on the DOCSIS 3.0 standard, continues to evolve, and we are deploying alternatives such as DOCSIS 3.1 and FTTH in certain markets. Over time, 5G and other mobile technologies may also be considered as viable alternatives for fixed services. Technological change is also impacting the capabilities of the equipment our customers use, such as mobile handsets and set-top boxes, and potential changes in this area may impact demand or the cost of providing our services in the future.

• Changes in consumer behavior and needs. In recent years, consumption of mobile services has shifted from voice and SMS to data services due largely to changes in consumer patterns, including for example the adoption and growth of social media, made possible by new smartphones on 4G and 5G networks capable of high quality live video streaming.

• Political changes. The countries where we operate are characterized as having a high degree of political uncertainty, and electoral cycles can sometimes impact business investment, consumer confidence, and

broader economic activity, as well as inflation and foreign exchange rates. Moreover, changes in government can sometimes produce significant changes in taxation and regulation of the telecommunications industry that can have a material impact on our business and financial results.

•Cost-reduction measures. Beginning in 2022, and continuing throughout 2023 and 2024, we implemented a broad-based efficiency program (initially called "Project Everest"), and we incurred severance and other restructuring costs of approximately $87 million in 2023 and $115 million in 2024.

Additional factors and trends affecting our performance and the results of operations are set out in "Key Information—Risk Factors."

Factors affecting comparability of prior periods

Acquisitions

In the years ended December 31, 2024, 2023 and 2022, the Group also completed certain other minor acquisitions.

Joint operation in Colombia

On February 26, 2024, Tigo Colombia and Coltel signed an agreement to share their mobile networks. This collaboration involves 2 new joint arrangements. (both qualifying as joint operations). Certain assets and liabilities were derecognized in Tigo Colombia with the subsequent recognition of Tigo's Colombia 50% share in the corresponding joint operation. Additionally, in accordance with IFRS 5, certain assets and related liabilities are kept as of December 31, 2024 as "held for sale." See note E.4.2. to our audited consolidated financial statements for additional details.

Discontinued operations

Tanzania

On April 19, 2021, we announced the signing of an agreement for the sale of our operations in Tanzania to a consortium led by Axian. The transaction was completed on April 5, 2022 for initial cash consideration of approximately $101 million (subject to final price adjustments).

Our segments

Our management determines operating and reportable segments based on the reports that are used by the chief operating decision maker (the "CODM") to make strategic and operational decisions from both a business and geographic perspective. During the latter half of 2023, Millicom implemented significant organizational changes to focus on driving profitable growth with a leaner corporate structure. The Group also adopted a decentralized approach to streamline decision-making processes and enhance agility to improve profitability and shareholder value. Following these organizational changes, and considering the information being reviewed by the CODM to assess performance and allocate resources, Millicom's operating segments were redefined to align with its countries of operation. Our reportable segments consist of Guatemala, Colombia, Panama, Bolivia, Honduras, Paraguay and Other, which includes Nicaragua, Costa Rica and El Salvador.

Honduras joint venture

Though we hold a majority ownership interest in the entities that own the Honduras joint venture, the board of directors is composed of equal numbers of directors from Millicom and from our respective partners, and the shareholders’ agreements for each entity require unanimous board approval for key decisions relating to the activities of these entities. As such, we have determined that neither party controls the entities, and we therefore account for our investments in these entities as equity method investments.

We report our share of the net income of this joint venture in our consolidated statement of income under the caption “Share of profit in joint ventures.”

For additional details on the Honduras joint venture, see note A.2. to our audited consolidated financial statements.

Our customer base

We generate revenue mainly from the mobile and fixed and other services that we provide and to a lesser extent, from the sale of telephone and other equipment. For a description of our services, see “Information on the Company—Business Overview—Our services.” Our results of operations are therefore dependent on both the size of our customer base and on the amount that customers spend on our services.

We measure the amount that customers spend on our services using a telecommunications industry metric known as ARPU, or average revenue per user per month. We define ARPU for our Mobile customers as (x) the total mobile and mobile financial services revenue (excluding revenue earned from tower rentals, call centers, data and mobile virtual network operators, visitor roaming, national third parties roaming and mobile telephone equipment sales revenue) for the period, divided by (y) the average number of Mobile subscribers for the period, divided by (z) the number of months in the period. We define ARPU for our Home customers as (x) the total home revenue (excluding equipment sales and TV advertising) for the period, divided by (y) the average number of customer relationships for the period, divided by (z) the number of months in the period.

We provide certain customer data below that we believe will assist investors in understanding our performance and to which we refer later in this section in discussing our results of operations.

The following table sets forth group revenue opened by:


	Year ended December 31,
	2024	2023	Percentage Change
	Group	Group	Group
	(U.S. dollars in millions, except percentages)
Mobile revenue	3,159	2,993	5.5%
Fixed and other service revenue	2,175	2,192	(0.8)%
Other revenue	84	65	27.9%
Service revenue(i)	5,417	5,250	3.2%
Telephone and equipment revenue	387	411	(5.8)%
Revenue	5,804	5,661	2.5%

(i) Service revenue is revenue related to the provision of ongoing services such as monthly subscription fees for mobile and broadband, airtime and data usage fees, interconnection fees, roaming fees, mobile finance service commissions and fees from other telecommunications services such as data services, short message services, installation fees and other value added services excluding telephone and equipment sales.

Revenue

Revenue increased by 2.5% for the year ended December 31, 2024 to $5,804 million from $5,661 million for the year ended December 31, 2023. The increase in revenue of $143 million reflects positive revenue growth in most

countries, partially offset by lower revenue in Paraguay. Additionally, see "—Revenue and EBITDA by Reportable Segments for the years ended December 31, 2024 and 2023" below.

Equipment, programming and other direct costs

Equipment, programming and other direct costs decreased by 5.8% for the year ended December 31, 2024 to $1,420 million from $1,507 million for the year ended December 31, 2023, reflecting savings from our efficiency program.

Operating expenses

Operating expenses decreased by 6.2% for the year ended December 31, 2024 to $1,915 million from $2,043 million for the year ended December 31, 2023, reflecting savings from our efficiency program. For the year ended December 31, 2024 operating expenses include severance costs related to Project Everest of $115 million and also one-off costs related to buy-out discussions.

Depreciation

Depreciation decreased by 6.4% for the year ended December 31, 2024 to $916 million from $978 million for the year ended December 31, 2023. The decline is mostly due to the sale of towers and reclassification of assets to held for sale in Colombia, and, to a lesser extent, longer useful lives in fiber assets.

Amortization

Amortization decreased 11.6% for the year ended December 31, 2024 to $319 million from $360 million for the year ended December 31, 2023, as we stopped amortizing assets held for sale related to the mobile network sharing agreement in Colombia.

Share of profit in joint ventures

Share of profit in joint ventures increased by 26.7% for the year ended December 31, 2024 to $54 million from $42 million for the year ended December 31, 2023, reflecting the increased profitability of our Honduras joint venture (attributable to higher revenue performance and lower operational costs).

Other operating income (expenses), net

Other operating income (expenses), net, for the year ended December 31, 2024 was $54 million, an increase from income of $10 million for the year ended December 31, 2023, due mainly to a one-time gain of $28 million stemming from the creation of the shared mobile network and also due to a one-time gain of $13 million on the sale of towers, both in Colombia.

Interest and other financial expenses

Interest and other financial expenses increased by 0.5% for the year ended December 31, 2024 to $716 million from $712 million for the year ended December 31, 2023, reflecting higher commissions on the purchase of U.S. dollars by our operations in Bolivia, partially offset by lower interest expense on our reduced debt position.

Interest and other financial income

Interest and other financial income increased by 61.4% for the year ended December 31, 2024 to $46 million from $28 million for the year ended December 31, 2023, mainly due to discounts on debt repurchases and higher interest income earned.

Other non-operating (expenses) income, net

Other non-operating (expenses) income, net, increased by $155 million for the year ended December 31, 2024 to an expense of $119 million, from an income of $36 million for the year ended December 31, 2023. The increase was mainly due to a provision for an adverse legal ruling as well as foreign exchange losses, mainly in Colombia and Paraguay.

Loss from other joint ventures and associates, net

Loss from other joint ventures and associates, net, increased by $3 million for the year ended December 31, 2024 to nil from a loss of $3 million for the year ended December 31, 2023, that was attributable to our former operations in Ghana.

Tax expenses

Tax expenses, decreased by 33.7% for the year ended December 31, 2024 to $281 million from $424 million for the year ended December 31, 2023. The decrease is mainly due to the write-off of deferred tax assets and value-added tax credits in Colombia in 2023.

Net profit (loss) for the year

Net profit for the year increased by $513 million for the year ended December 31, 2024 to a gain of $268 million, from a loss of $245 million for the year ended December 31, 2023. Profit for the year from continuing operations increased by $520 million for the year ended December 31, 2024 to a gain of $271 million, from a loss of $249 million for the year ended December 31, 2023 for the reasons stated above. Profit (loss) for the year from discontinued operations, net of tax decreased by $8 million for the year ended December 31, 2024 to a loss of $3 million as compared to a profit of $4 million for the year ended December 31, 2023.

Revenue and EBITDA by Reportable Segments for the years ended December 31, 2024 and 2023

Our reportable segments consist of Guatemala, Colombia, Panama, Bolivia, Honduras, Paraguay and Other segments, which includes Nicaragua, Costa Rica and El Salvador. The Honduras segment presents the results of our Honduras joint venture as if it were fully consolidated, as this reflects the way management reviews and uses internally reported information to make decisions. The following table sets forth our revenue by reportable segments for the years ended December 31, 2024 and 2023. See note B.3. to our audited consolidated financial statements for additional details.

Inter-segment and other eliminations (i)	(638)	(631)	(1.2)%
Total Group	5,804	5,661	2.5%

Guatemala represented 25%, Colombia represented 21%, Panama, Bolivia, Honduras and Paraguay each represented between 9% and 12%, and Other represented together 14% of our total revenue by reportable segment for the year ended December 31, 2024. Panama and Colombia experienced the highest relative increase in revenues of 5.1%, due to robust growth in the Mobile business (and in Panama, also due to two new large B2B contracts). In contrast, revenue declined 1.6% in Paraguay due to the weaker foreign exchange rate. Other increase was mainly driven by higher revenue in the Mobile business for El Salvador and Nicaragua.

Other	391	352	11.1%

(i) While the Millicom Group holds a 66.67% equity interest in the Honduras joint venture (which is accounted for using the equity method), its performance is reviewed by the CODM in a similar manner as the Group's fully owned operations and is therefore shown as a separate operating segment at 100%. However, such amounts are removed for reconciliation to the Group's total revenue. See note B.3. to our audited consolidated financial statements for further details on segment information.

The Guatemala, Colombia, and Panama segments generated the highest EBITDA in 2024. While the Company's restructuring program produced meaningful cost savings in all country segments, positively impacting profitability in 2024, the following noteworthy factors also affected the comparison with 2023:

•Guatemala EBITDA benefited from higher prepaid mobile ARPU;

•Colombia EBITDA benefited from postpaid customer and prepaid mobile ARPU growth, which more than offset a decline in the Home business;

•Panama EBITDA benefited from mobile customer and ARPU growth, as well as new B2B contracts;

•Bolivia EBITDA benefited from higher mobile and B2B revenue, partially offset by lower revenue in Home, where we have continued to prioritize profitability over growth;

•Paraguay EBITDA benefited from mobile customer and ARPU growth and continued strong performance in B2B; and

•Other EBITDA benefited from growth in mobile offsetting a decline in Home.

Revenue	5,661	5,624	0.7%

Revenue

Revenue increased by 0.7% for the year ended December 31, 2023 to $5,661 million from $5,624 million for the year ended December 31, 2022. The increase in revenue of $37 million reflects positive revenue growth in most countries, partially offset by lower revenue in Guatemala, Colombia and Bolivia. Additionally, see "—Revenue and EBITDA by Reportable Segments for the years ended December 31, 2023 and 2022" below.

Equipment, programming and other direct costs

Equipment, programming and other direct costs increased by 0.1% for the year ended December 31, 2023 to $1,507 million from $1,506 million for the year ended December 31, 2022. Equipment, programming and other direct costs increased by less than the increase in revenue due to a change in revenue mix, as revenue from services increased, while revenue from the sale of equipment declined during the period.

Operating expenses

Operating expenses increased by 8.1% for the year ended December 31, 2023 to $2,043 million from $1,890 million for the year ended December 31, 2022. Of the $152 million increase, $87 million was for severance and other restructuring costs related to Project Everest, and $19 million was related to one-off legal cases. During 2023, we also incurred $33 million in legal costs and applicable value-added taxes related to the subpoenas that we received from the DOJ. The remaining portion of the increase was mostly related to higher share-based compensation and non-recurring costs related to the prior buyout discussions. Excluding these unusual items, operating expenses were about flat year-on-year, as cost savings initiatives offset the impact of elevated inflation in some markets.

Depreciation

Depreciation decreased by 2.1% for the year ended December 31, 2023 to $978 million from $999 million for the year ended December 31, 2022. The decline is mostly due to a 2023 prospective change in the useful lives for tower and civil works assets.

Amortization

Amortization increased 4.5% for the year ended December 31, 2023 to $360 million from $345 million for the year ended December 31, 2022. The increase is mostly due to the renewal of spectrum licenses in Colombia during 2023.

Share of profit in joint ventures

Share of profit in joint ventures increased by 30.6% for the year ended December 31, 2023 to $42 million from $32 million for the year ended December 31, 2022. The increased profitability of our Honduras joint venture reflects improved operational performance and lower depreciation, partially offset by severance.

Other operating income (expenses), net

Other operating income (expenses), net increased by $12 million for the year ended December 31, 2023 to an income of $10 million from an expense of $2 million for the year ended December 31, 2022. The increase reflects the disposal of assets (such as copper wires no longer in use) in 2023, as well as the negative impact of a software contract termination in 2022.

Interest and other financial expenses

Interest and other financial expenses increased by 15.5% for the year ended December 31, 2023 to $712 million from $617 million for the year ended December 31, 2022, reflecting the impact of higher interest rates on our variable debt and commissions on the purchase of U.S. dollars by our operations in Bolivia.

Interest and other financial income

Interest and other financial income increased by 58.0% for the year ended December 31, 2023 to $28 million from $18 million for the year ended December 31, 2022 due to a $12 million gain on the repurchase of bonds.

Other non-operating (expenses) income, net

Other non-operating (expenses) income, net, increased by $114 million for the year ended December 31, 2023 to an income of $36 million from an expense of $78 million for the year ended December 31, 2022. The increase was mainly due to foreign exchange gains in 2023 compared to foreign exchange losses in 2022.

Loss from other joint ventures and associates, net

Loss from other joint ventures and associates, net increased by $2 million for the year ended December 31, 2023 to $3 million from a result of nil for the year ended December 31, 2022 that was attributable to our former operations in Ghana.

Tax expense

Tax expense increased by 90.8% for the year ended December 31, 2023 to $424 million from $222 million for the year ended December 31, 2022. The increase is mainly due to the write-off of deferred tax assets and value-added tax credits in Colombia.

Net profit (loss) for the year

Net profit for the year decreased by $374 million for the year ended December 31, 2023 to a loss of $245 million from a profit of $129 million for the year ended December 31, 2022. Profit for the year from continuing operations decreased by $265 million for the year ended December 31, 2023 to a loss of $249 million from a profit of $16 million for the year ended December 31, 2022 for the reasons stated above. Profit (loss) for the year from discontinued operations, net of tax decreased by $109 million for the year ended December 31, 2023 to $4 million as compared to a profit of $113 million for the year ended December 31, 2022.

Revenue and EBITDA by Reportable Segments for the years ended December 31, 2023 and 2022

Our reportable segments consist of Guatemala, Colombia, Panama, Bolivia, Honduras, Paraguay and Other, which includes Nicaragua, Costa Rica and El Salvador. The Honduras segment presents the results of our Honduras joint venture as if it were fully consolidated, as this reflects the way management reviews and uses internally reported information to make decisions. The following table sets forth our revenue by reportable segments for the years ended December 31, 2023 and 2022. See note B.3. to our audited consolidated financial statements for additional details.


Revenue by Reportable Segments	Year ended December 31,		Percentage Change
	2023	2022
	(U.S. dollars in millions, except percentages)
Guatemala	1,564	1,618	(3.3)%

Inter-segment and other eliminations (i)	(631)	(605)	(4.2)%
Total Group	5,661	5,624	0.7%

Guatemala represented 25%, Colombia represented 21%, Panama, Bolivia, Honduras and Paraguay each represented between 9% and 11%, while other segments collectively represented 14% of our total revenue by reportable segments for the year ended December 31, 2023. Panama experienced the highest relative increase in revenues of $68 million or 10.4%, due to new large B2B contracts and robust growth in the Mobile business. In contrast, the weakest performance was in Guatemala, where revenue declined 3.3% due to intense competition in prepaid mobile. In Colombia, revenue declined 1.6%, as a decline in equipment revenue more than offset growth in service revenue.


EBITDA by Reportable Segments	Year ended December 31		Percentage Change
	2023	2022

Honduras (i)	272	262	4.0%
Paraguay	236	245	(3.4)%
Other	352	330	6.8%

(i) While the Millicom Group holds a 66.67% equity interest in the Honduras joint venture (which is accounted for using the equity method), its performance is reviewed by the CODM in a similar manner as the Group's fully owned operations and is therefore also shown as a separate operating segment at 100%. However, such amounts are removed for reconciliation to the Group's total revenue. See note B.3. to our audited consolidated financial statements for further details on segment information.

The Guatemala, Colombia, and Panama segments generated the highest EBITDA in 2023. During 2023, each of our segments incurred significant severance and other restructuring costs related to the implementation of Project Everest, and this impacted comparisons to 2022. In addition to the impact of Project Everest, the following noteworthy factors affected the comparison with 2022 for some of our segments:

•Guatemala was impacted by pricing pressure caused by a more competitive environment;

•Colombia was impacted by service revenue growth in our Mobile business and lower costs stemming from reduced commercial activity in our Home business, partially offset by the impact of two adverse legal rulings;

•Panama was impacted by higher selling and marketing expenses (in addition to the aforementioned severance impact), which were partially offset by continued service revenue growth in Mobile and new B2B contracts, as well as a favorable legal ruling in 2022;

•Bolivia was impacted by a change in regulation, which capped the overage rates on prepaid plans and took effect in August 2022, and a regulatory fine for a service outage related to a prior year; and

•Other was impacted by the appreciation of the Costa Rican colon, as it drove very strong EBITDA growth from that country.

Use of Non-IFRS Terms

Non-IFRS Measures

This Annual Report contains financial measures that are not prepared in accordance with IFRS. These measures are referred to as “non-IFRS” measures, and they are not uniformly or legally defined financial measures. Non-IFRS measures are not substitutes for IFRS measures in assessing our overall operating performance. Because non-IFRS measures are not determined in accordance with IFRS, and are susceptible to varying calculations, non-IFRS measures may not be comparable to other similarly titled measures presented by other companies.

Non-IFRS measures are included in this Annual Report because they are used by our management, and we believe they provide investors with additional information for the analysis of Millicom’s results of operations, particularly in evaluating performance from one period to another. Millicom’s management uses non-IFRS measures to make operating decisions, as they facilitate additional internal comparisons of Millicom’s performance to historical results, and provides them to investors as a supplement to Millicom’s reported results for additional insight into Millicom’s operating performance. Millicom’s Compensation and Talent Committee uses certain non-IFRS measures when assessing the performance and compensation of employees, including Millicom’s Executive Directors.

Non-IFRS measures have limitations as an analytical tool. The non-IFRS measures used by Millicom may be calculated differently from, and therefore may not be comparable to, similarly titled measures used by other companies. In addition, these non-IFRS measures should not be considered in isolation as a substitute for, or as superior to, financial measures calculated in accordance with IFRS. Millicom’s financial results calculated in accordance with IFRS and reconciliations to those financial statements should be carefully evaluated.

Critical accounting policies

The preparation of our consolidated financial statements requires management to use judgment in applying accounting policies. It also requires the use of certain critical accounting estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. These estimates are based on management’s best knowledge of current events, actions and best estimates as of a specified date, and actual results may ultimately differ from these estimates. Areas involving a higher degree of judgment or complexity,

or areas where assumptions and estimates are significant to the financial statements are described in “Introduction—Judgments and critical estimates” in the notes to our audited consolidated financial statements, and in the notes referenced therein.

For a description of new or amended IFRS accounting standards to which we are subject, see “Introduction—New and amended IFRS accounting standards” in the notes to our audited consolidated financial statements.

Liquidity and Capital Resources

Overview

The Millicom Group’s sources of funds are cash from operations, internal and external financing as well as proceeds from the disposal of assets. The Millicom Group finances its operations centrally at the MIC S.A. level or alternatively, where it deems it more cost effective to do so, at the operational level.

In particular, we seek to finance the costs of deploying and expanding our fixed and mobile networks mainly at the operating level on a country-by-country basis, utilizing credit facilities provided by banks and entering into leases, obtaining financing from the debt capital markets, and seeking funding from export credit agencies and development financial institutions such as the Inter-American Development Bank.

If we decide to acquire other businesses, we expect to fund these acquisitions from cash resources, borrowings under existing credit facilities, through new borrowings, including under new credit facilities or issuances of debt securities, and, if necessary, we may issue equity to raise funds.

As of December 31, 2024, our consolidated cash and cash equivalents balance was $699 million (of which $501 million was at the holdings level and $198 million was at the operating subsidiaries level). As of December 31, 2023 and 2022, our consolidated cash and cash equivalents balance was $775 million (of which $384 million was at the holdings level and $391 million was at the operating subsidiaries level) and $1,039 million (of which $675 million was at the holdings level and $364 million was at the operating subsidiaries level), respectively. If funds at the foreign operating subsidiaries level are repatriated, taxes on each type of repatriation and each country would need to be accrued and paid, where applicable.

As of December 31, 2024, our total consolidated indebtedness (excluding lease liabilities) was $5,815 million. As of December 31, 2023 and 2022 our total consolidated indebtedness (excluding lease liabilities) was $6,697 million and $6,804 million, respectively.

We believe that our available cash and cash equivalents, borrowings and funds from our operating subsidiaries will be sufficient to meet our projected operating and capital expenditure requirements for at least the next 12 months.

Cash repatriation

Cash repatriation is dependent on operating and financial performance of our operations. Cash repatriation is accomplished through a combination of dividends, fees and shareholder loan repayments.

The following table sets forth cash repatriated to MIC S.A. from our subsidiaries and joint ventures for the periods presented:


	December 31,
	2024	2023	2022 (i)
	(U.S. dollars in millions)
Subsidiaries	393	566	1,565
Joint ventures	89	86	85
Total	482	652	1,651

(i) Cash repatriated from subsidiaries as of December 31, 2022 includes approximately $900 million of proceeds from the issuance of the 5.125% Senior Notes due 2032, which were used to partially refinance the bridge loan that we obtained to fund the acquisition of the remaining 45% equity interest in our Guatemala business.

In each case, the repatriated cash was principally used to cover corporate expenses, service corporate debt and pay corporate taxes.

Some of our operating subsidiaries and joint ventures have covenants on debt outstanding that impose restrictions on their ability to upstream cash to MIC S.A. As a result of these restrictions, significant cash or cash equivalent balances may be held from time to time at our operating subsidiaries and joint ventures.

Cash flows

Set forth below is a comparative discussion of our cash flows, which includes cash flows from discontinued operations.

Years ended December 31, 2024 and 2023

For the year ended December 31, 2024, cash provided by operating activities was $1,603 million, compared to $1,223 million for the year ended December 31, 2023. The increase is mainly due to better results for the year ended December 31, 2024 compared to the year ended December 31, 2023 (see "—Operating Results").

Cash used in investing activities was $604 million for the year ended December 31, 2024, compared to $1,116 million for the year ended December 31, 2023. In the year ended December 31, 2024, Millicom used $540 million to purchase property, plant and equipment, $135 million to purchase spectrum and licenses and $94 million to purchase other intangible assets, and these items were partially offset by proceeds of $66 million in dividends from joint ventures and $58 million from the sale of property, plant and equipment such as towers. For the year ended December 31, 2023, Millicom used $814 million to purchase property, plant and equipment, $236 million to purchase spectrum and licenses and $133 million to purchase intangible assets, and these items were partially offset by proceeds of $63 million in dividends from joint ventures and $17 million from the sale of property, plant and equipment.

For the year ended December 31, 2023, cash provided by operating activities was $1,223 million, compared to $1,284 million for the year ended December 31, 2022. The decrease is mainly due to higher working capital due to foreign exchange for the year ended December 31, 2023 compared to the year ended December 31, 2022.

Cash used in investing activities was $1,116 million for the year ended December 31, 2023, compared to $1,104 million for the year ended December 31, 2022. In the year ended December 31, 2023, Millicom used $814 million to purchase property, plant and equipment, $236 million to purchase spectrum and licenses and $133 million to purchase other intangible assets, and these items were partially offset by proceeds of $63 million in dividends from joint ventures, and $17 million from the sale of property, plant and equipment such as copper wires and buildings. For the year ended December 31, 2022, Millicom used $283 million for the acquisition of the non-controlling interest of Tigo Panama, $800 million to purchase property, plant and equipment and $179 million to purchase intangible assets and licenses, and these items were partially offset by proceeds of $10 million in dividends from joint ventures, $152 million from the disposal of subsidiaries and joint ventures, and $21 million from the sale of property, plant and equipment such as towers and buildings.

Cash used in financing activities was $377 million for the year ended December 31, 2023, compared to $1 million for the year ended December 31, 2022.

As of December 31, 2024, we had commitments to purchase network equipment, other fixed assets and intangible assets with a value of $285 million from a number of suppliers, of which $215 million was within one year and $70 million more than one year. Out of these commitments, $19 million relate to the Group’s share in joint ventures ($19 million within one year). We expect to meet these commitments from our current cash balance and from cash generated from our operations.

Financing

We seek to finance our operations on a country-by-country basis when we determine it to be more cost and risk effective. As local financial markets become more developed, we have been able to finance increasingly at the level of our operations in local currency and on a generally non-recourse basis to MIC S.A. As of December 31, 2024, 59% ($3,414 million) of our total consolidated debt of $5,815 million (excluding lease liabilities, but including vendor financing) was at the operational level (excluding our Honduras joint venture) and generally non-recourse to MIC S.A., and 41% of this debt was denominated in local currency. In addition, as of December 31, 2024, our joint venture in Honduras had $364 million of debt excluding lease liabilities which was non-recourse to MIC S.A. From time to time, we may provide support to our subsidiaries and service indebtedness that is held at the operational level.

Consolidated indebtedness

Millicom’s total consolidated debt and financing (that is, excluding lease liabilities but including vendor financing) as of December 31, 2024 was $5,815 million (December 31, 2023: $6,697 million). Our total consolidated net debt (representing debt and financial liabilities, including derivative instruments (assets and liabilities), less cash and pledged and time deposits) was $5,174 million (December 31, 2023: $5,956 million).

Millicom's lease liabilities as of December 31, 2024 were $954 million. 99% of our consolidated lease liabilities, or $949 million, was at the operational level (excluding our joint venture in Honduras) and non-recourse to MIC S.A. Including lease liabilities, Millicom's total consolidated financial obligations as of December 31, 2024 were $6,769 million (December 31, 2023: $7,739 million). Our total consolidated net financing obligations (that is, net debt plus lease liabilities) were $6,128 million (December 31, 2023: $6,999 million). In 2023, the definition of net debt changed to include derivative financial instruments in order to have a more comprehensive view of our financial obligations. 2022 figures have also been represented accordingly.

See note C.6. to our audited consolidated financial statements included elsewhere in this Annual Report for a reconciliation of total consolidated debt and financing to total consolidated net debt. Our consolidated interest and other financial expenses for the year ended December 31, 2024 were $716 million and for the years ended December 31, 2023 and 2022 were $712 million and $617 million, respectively.

The following table sets forth our consolidated debt and financing by entity or operational entity location for the periods indicated:

For a more detailed description of our outstanding financial obligations, including our credit facilities and outstanding bond or note issuances, see note C.3. to our audited consolidated financial statements.

Our financing facilities at the MIC S.A. level are subject to a number of financial covenants including leverage covenants. In addition, most financings at the MIC S.A. level contain restrictions on sale of businesses or significant assets within the businesses.

Our financing facilities at the operational level are subject to a number of financial covenants including leverage and restricted payment covenants, and in certain cases, debt service coverage and debt to earnings covenants. In addition, some of the financings at the operational level contain restrictions on sale of businesses or significant assets within the businesses.

From time to time, we repurchase certain outstanding indebtedness at both the MIC S.A. level and the operational level. For example, during 2024, MIC S.A. redeemed all of its 6.625% Senior Notes due 2026 for approximately $148 million and repurchased a portion of its 4.500% Senior Notes due 2031, 6.250% Senior Notes due 2029 and 5.125% Senior Notes due 2028 on the open market for approximately $17 million, $59 million and $90 million, respectively. During 2024, Comcel (Guatemala) repurchased and cancelled a portion of the 5.125% Senior Notes due 2032 for approximately $88 million, Telecomunicaciones Digitales, S.A. repurchased and cancelled some of its 4.500% Senior Notes due 2030 and Telefónica Celular del Paraguay, S.A.E. repurchased and cancelled a portion of its 5.875% Senior Notes due 2027 for approximately $63 million. See Note C.3.1. to our audited consolidated financial statements. We and our subsidiaries expect to continue to repurchase debt in pursuit of our leverage target, and may do so in the open market, in privately negotiated transactions, through tender or exchange offers, or otherwise, and we and our subsidiaries may redeem debt that we or they are permitted to redeem under its terms.

Indebtedness of joint ventures

With respect to the Honduras joint venture, total debt excluding lease liabilities as of December 31, 2024 was $364 million. As of December 31, 2024, our joint venture in Honduras had lease liabilities of $87 million. The total net debt (representing debt and financial liabilities, including derivative instruments (assets and liabilities), less cash and pledged and time deposits) was $309 million. Annual interest expense for the Honduras joint venture for the years ended December 31, 2024, 2023 and 2022 was $39 million, $29 million and $29 million, respectively.

See "Corporate Governance—Board Governance—Board Profile: Skills and Experience" for more information on our directors and senior management.

Compensation

For the year ended December 31, 2024, the total compensation paid to MIC S.A.’s directors was $1.3 million. The total compensation for the year ended December 31, 2024 to MIC S.A.'s officers (including the amounts set aside or accrued by Millicom to provide pension, retirement or similar benefits) was $26 million.

The Company provides information on the individual compensation of its directors in its annual report filed with the Registre de Commerce et des Sociétés (Luxembourg Trade and Companies Register), the Société de la Bourse de Luxembourg S.A. (Luxembourg Stock Exchange) and the Commission de Surveillance du Secteur Financier (CSSF). As that annual report is made publicly available, the relevant individual compensation information it contains for directors is included below.

Remuneration of Directors

Decisions on annual remuneration of directors (tantièmes) are reserved by the Articles of Association to the general meeting of shareholders. Directors are prevented from voting on their own compensation. The remuneration of the non-executive members of the Board of Directors comprises an annual fee and shares of MIC S.A. The remuneration is 100% fixed. Non-executive directors do not receive any fringe benefits, pensions or any form of variable remuneration. No remuneration was paid by MIC S.A. to any of the non-executive directors in 2024 or 2023 from any other undertakings within the Millicom Group.

Director remuneration is proposed by the Nomination Committee and approved by the shareholders at the AGM or other shareholders’ meetings. In October 2023, the Nomination Committee proposed for approval at the 2024 AGM to keep the remuneration structure and not increase the amount of remuneration for each role for the non-executive directors. In accordance with resolution 19 adopted by the AGM on May 23, 2024, the Nomination Committee of Millicom was instructed to propose director remuneration for the period from the date of the 2024 AGM to the date of the AGM in 2025.

At the AGM held on May 23, 2024, MIC S.A.’s shareholders approved the compensation for the non-executive directors expected to serve from that date until the 2025 AGM consisting of two components: (i) cash-based compensation and (ii) share-based compensation. The share-based compensation is in the form of fully paid-up shares of MIC S.A. Such shares are provided from the Company’s treasury shares or, if permitted, alternatively issued within MIC S.A.’s authorized share capital exclusively in exchange for the allocation from the share premium reserve (i.e., for nil consideration from the relevant directors), in each case divided by the average Millicom closing share price on the Nasdaq in the United States for the three-month period ending April 30, 2024, or US$18.56 per share, provided that shares shall not be issued below the par value. Executive directors (i.e. those directors that received compensation as employees of MIC S.A.) did not receive any remuneration in their capacity as directors.

Director remuneration (Board and Committees) for the year ended December 31, 2024 and December 31, 2023 (covering the period from May 31, 2024 to the date of the AGM in May 2025 as resolved at the shareholder meeting on May 23, 2024) is set forth in the following table. See Board Committees section for details on those directors that are also committee members.

FINANCIAL INFORMATION

Consolidated Statements and Other Financial Information

Financial Statements

Consolidated financial statements are set forth under “Financial Statements.”

Legal Proceedings

General litigation

In the ordinary course of business, Millicom is a party to various litigation or arbitration matters in each jurisdiction in which we operate. The principal categories of litigation to which we are subject include the following:

• commercial claims, which include claims from third-party dealers, suppliers and customers alleging breaches or improper terminations of commercial agreements, or the charging of fees not in compliance with applicable law;

• regulatory claims, which consist primarily of consumer claims, as well as complaints regarding the locations of antennae and other equipment; and

• labor and employment claims, including claims for wrongful termination and unpaid severance or other benefits.

By category of litigation, commercial claims account for a majority of the litigation matters to which we are party by both number of cases and total potential exposure based on the amount claimed.

By geography, litigation matters in Colombia represent a majority of the litigation matters to which we are party by both number of cases and total potential exposure. This is due to the size of our operations in Colombia, the comparatively high general prevalence of litigation there, and consumer protection and quality of service regulations which facilitate claims against telecommunications companies.

In addition, from time to time, Millicom is subject to governmental and regulatory inquiries and investigations.

For additional details, see note G.3.1. to our audited consolidated financial statements.

Tax disputes

In addition to the litigation matters describe above, we have ongoing tax claims and disputes in most of our markets. Generally, these disputes relate to differences with the tax authorities following their completion of audits for prior tax years dating back to 2007 or challenges by the tax authorities to our interpretation of tax regulations. Examples of these challenges and disputes relate to issues such as the following:

• the applicability, deductibility or reporting of VAT or sales tax in Honduras, El Salvador and Costa Rica;

• withholding tax payable on commissions, interconnection services, roaming, services fees and finance leases in Bolivia, El Salvador, Guatemala, Honduras and Paraguay;

• the application of stamp tax on dividend payments in Guatemala;

• the deductibility of expenses and interest on shareholder loans and other debt instruments in El Salvador, Nicaragua and Costa Rica;

• the deductibility of management, royalty and service fees paid to MIC S.A. by our operations in El Salvador, Honduras and Nicaragua;

• deductibility of commissions and discounts on handsets in Honduras and El Salvador;

• the deductibility of expenses for depreciation and amortization in Colombia, Guatemala, Nicaragua and Paraguay;

•the application of the territoriality principle in the determination of the taxable base of municipal taxes in Colombia and Nicaragua; and

•withholding tax and deductibility of expenses due to the application of double tax treaties in Bolivia and Panama.

In many instances, the tax authorities seek to impose substantial penalties and interest charges while the disputed amounts remain unpaid, as we seek resolution through negotiations or court proceedings, resulting in significantly higher total claims than we expect the tax authorities will receive once the matter has been finally resolved. We work with the local tax authorities to substantiate claims or negotiate settlement amounts to close an audit, except in those instances where we are challenging or appealing the tax authorities’ claims.

For additional details, see note G.3.2. to our audited consolidated financial statements.

Taxation

Luxembourg Tax Considerations

The following information is of a general nature only on certain tax considerations effective in Luxembourg in relation to holders of shares in respect of the ownership and disposition of shares in MIC S.A. and does not purport to be a comprehensive description of all of the tax considerations that might be relevant to an investment decision in such company. It is included herein solely for preliminary information purposes and is not intended to be, nor should it be construed to be, legal or tax advice. The information contained herein is based on the laws presently in force in Luxembourg on the date hereof, and thus subject to any change in law that may take effect after such date. Shareholders in MIC S.A. should therefore consult their own professional advisers as to the effects of state, local or foreign laws, including Luxembourg tax law, to which they may be subject.

Please be aware that the residence concept used under the respective headings below applies for Luxembourg income tax assessment purposes only. Any reference in the present section to a tax, duty, levy, impost or other charge or withholding of a similar nature, or to any other concepts, refers to Luxembourg tax law or concepts only. Further, any reference to a resident corporate shareholder/taxpayer includes non-resident corporate shareholders/taxpayers carrying out business activities through a permanent establishment, a permanent representative or a fixed place of business in Luxembourg to which assets would be attributable. Also, please note that a reference to Luxembourg income tax encompasses corporate income tax (impôt sur le revenu des collectivités), municipal business tax (impôt commercial communal), a solidarity surcharge (contribution au fonds pour l’emploi), as well as personal income tax (impôt sur le revenu) generally. Corporate shareholders may further be subject to net wealth tax (impôts sur la fortune), as well as other duties, levies or taxes.

Corporate income tax, municipal business tax, as well as the solidarity surcharge invariably apply to most corporate taxpayers resident in Luxembourg for tax purposes. Individual taxpayers are generally subject to personal income tax and the solidarity surcharge. Under certain circumstances, where an individual taxpayer acts in the course of the management of a professional or business undertaking, municipal business tax may apply as well.

(a) Luxembourg withholding tax on dividends paid on MIC S.A. shares

Dividends distributed by MIC S.A. will in principle be subject to Luxembourg withholding tax at the rate of 15%. An exemption from Luxembourg withholding tax may apply under Article 147 of the Luxembourg income tax law (“LITL”) or under the specific provisions of a double tax treaty (if applicable).

Luxembourg resident corporate holders

No dividend withholding should apply on dividends paid by MIC S.A. to (i) a Luxembourg resident company if the conditions of Article 147 LITL are met, meaning that the Luxembourg residence corporate holder should be a collective entity covered by article 2 of the EU Parent Subsidiary (Council Directive 2011/96/EU of November 30, 2011), (ii) a fully taxable (capital) company not listed in the appendix to article 166 LITL, paragraph 10, or (iii) the Luxembourg State, a Luxembourg commune or a Luxembourg syndicate of communes or an undertaking of a Luxembourg public body or to a Luxembourg permanent establishment of a collective entity under (i), (ii) or (iii)), holding shares which meets the qualifying participation test (10% of the share capital or acquisition price of the shares of at least €1.2 million held or committed to be held for a minimum of 12 months).

Luxembourg resident individual holders

Luxembourg withholding tax on dividends paid by MIC S.A. to a Luxembourg resident individual holder may entitle such holder to a tax credit for the tax withheld.

Non-Luxembourg resident holders

Non-Luxembourg resident shareholders of MIC S.A. should benefit from a withholding tax exemption if the conditions of Article 147 LITL are met, meaning a 10% shareholding or share acquisition price of €1.2 million held or committed to be held for 12 consecutive months, and that the non-Luxembourg resident should either be (i) an entity which falls within the scope of Article 2 of the European Council Directive 2011/96/EU, as amended (the “Parent-Subsidiary Directive”) and that is not excluded to benefit from this directive under its mandatory general anti-avoidance rule as implemented in Luxembourg, (ii) a corporate holder subject to a tax comparable to Luxembourg corporate income tax (at least 8.5% for fiscal year 2024 and 8% for fiscal year 2025) and that is resident in a country having concluded a double tax treaty with Luxembourg (such as the United States), (iii) a corporate holder subject to a tax comparable to Luxembourg corporate income tax (at least 8.5% for fiscal year 2024 and 8% for fiscal year 2025) resident in a State member of the European Economic Area other than a Member State of the EU (or to a Luxembourg permanent establishment of such company) or (iv) a corporate holder resident in Switzerland subject to corporate income tax in Switzerland without benefiting from a tax exemption.

Non-Luxembourg resident holders which do not fall within the scope of Article 147 LITL withholding tax exemption but resident in a State with which Luxembourg has concluded a double tax treaty may claim a reduced withholding tax under the conditions set forth in the relevant double tax treaty.

In the case the non-Luxembourg resident holder fulfills the requirements to benefit from a withholding tax exemption or is entitled to a reduced withholding tax under an applicable double tax treaty but has been subject to this 15% withholding tax, it may claim a refund from the Luxembourg tax administration.

(b) Luxembourg income tax on dividends and capital gains received from MIC S.A. shares

Fully taxable resident corporate shareholders

During fiscal year 2024, for resident corporate taxpayers, dividends (and other payments) derived from shares held in a company and capital gains realized on the sale of shares in a company are, in principle, fully taxable and thus subject to a combined corporate income tax rate of 24.94% (for resident corporate taxpayers established in Luxembourg City and having a tax base exceeding EUR 200,000), and since January 1, 2025 to a combined corporate income tax rate of 23.87% (for resident corporate taxpayers established in Luxembourg City and having a tax base exceeding €200,000), except that, as described in further detail below, (i) dividends can benefit either from a full

exemption if the conditions of article 166 LITL are met or from a 50% exemption if the conditions of Article 115 (15a) LITL are met, and (ii) capital gains realized by resident corporate shareholders are fully exempt if the conditions of the Grand Ducal Decree of December 21, 2002 (as amended), are fulfilled.

Under the Luxembourg participation exemption on dividends as implemented by Article 166 LITL, dividends derived from shares may be exempt from income tax at the level of the resident corporate shareholder if cumulatively, (i) the shareholder is either (a) a fully taxable resident collective entity taking one of the forms listed in the appendix to paragraph 10 of Article 166 LITL, (b) a fully taxable resident corporation not listed in the appendix to paragraph 10 of Article 166 LITL, (c) a permanent establishment of a collective entity referred to in Article 2 of the Parent-Subsidiary Directive, (d) a permanent establishment of a corporation resident in a State with which the Grand Duchy of Luxembourg has signed an agreement in an attempt to avoid double taxation, or (e) a permanent establishment of a corporation or a cooperative society resident in a State party to the European Economic Area Agreement other than a Member State of the European Union, (ii) the subsidiary is either (a) a collective entity referred to in Article 2 of the Parent-Subsidiary Directive, (b) a fully taxable resident corporation not listed in the appendix to paragraph (10) of Article 166 LITL, or (c) a non-resident corporation fully subject to a tax corresponding to the Luxembourg corporate income tax, and (iii) the shareholder has held or commits itself to hold, for an uninterrupted period of at least 12 months, a participation representing at least 10% in the share capital of the subsidiary or an acquisition price of at least €1.2 million. Liquidation proceeds are deemed to be a received dividend and may be exempt under the same conditions. The participation through an entity that is transparent for Luxembourg income tax purposes is to be considered as direct participation in proportion to the amount held in the net assets invested in that tax transparent entity.

The Luxembourg participation exemption regime may be denied if the income is (i) deductible in the other EU Member State paying such income or (ii) paid as part of an arrangement or a series of arrangements that, having been put into place with the main purpose or one of the main purposes of obtaining a tax advantage that defeats the object or purpose of the Parent-Subsidiary Directive, is not genuine having regard to all relevant facts and circumstances. For the purposes of this anti-avoidance rule, an arrangement, which may comprise several steps or parts, or a series of arrangements, is considered as not genuine to the extent that it is not put into place for valid commercial reasons that reflect economic reality.

Expenses, including interest expenses and impairments, in direct economic relation with the shareholding held by a resident corporate shareholder should not be deductible for income tax purposes up to the amount of any exempt dividend derived during the same financial year. Expenses exceeding the amount of the exempt dividend received from such shareholding during the same financial year should remain deductible for income tax purposes.

If the conditions of the Luxembourg participation exemption, as described above, are not met, 50% of the gross amount of dividends may be exempt from corporate income tax in accordance with Article 115 (15a) LITL if such dividends are received from (i) a fully taxable corporation resident in Luxembourg, (ii) a corporation (a) resident in a State with which the Grand Duchy of Luxembourg has signed an agreement in an attempt to avoid double taxation, and (b) fully subject to a tax corresponding to the Luxembourg corporate income tax, or (iii) a company resident in a Member State of the European Union and referred to in Article 2 of the Parent-Subsidiary Directive.

Capital gains realized on shares by resident corporate shareholders may be exempt from corporate income tax if the conditions mentioned above under the Luxembourg participation exemption on dividends are met, except that the acquisition price must be of at least €6 million instead of €1.2 million. The participation through an entity that is transparent for Luxembourg income tax purposes is to be considered as direct participation in proportion to the amount held in the net assets invested in that tax transparent entity. Taxable gains are determined as being the difference between the price for which the shares have been disposed of and the lower of their cost or book value.

Capital gains realized upon the disposal of shares should remain taxable for an amount corresponding to the sum of the expenses related to the shareholding and impairments recorded on the shareholding that reduced the taxable basis of the resident corporate shareholder in the year of disposal or in previous financial years.

Effective from fiscal year 2025, a taxpayer residing in Luxembourg may elect to forgo the advantages conferred by the Luxembourg participation exemption concerning dividends, liquidation proceeds, and capital gains. Additionally, the taxpayer may waive the 50% tax exemption applicable to dividend income derived from a qualifying shareholding or realized from the disposal of a qualifying shareholding.

This election is permissible exclusively in instances where the Luxembourg participation exemption regime would have been applicable based on the acquisition price criterion, specifically, a threshold of €1.2 million for dividends and liquidation proceeds, and €6 million for capital gains. It is important to note that this option to opt out is not available if

the taxpayer would have qualified for the Luxembourg participation exemption regime solely by meeting the 10% holding threshold criterion.

The waiver must be formally exercised for each individual tax year and for each respective shareholding. In the absence of such an election, the Luxembourg participation exemption regime will be automatically applied, provided that all requisite conditions are satisfied.

Resident corporate shareholders with a special tax regime

A resident corporate shareholder that is governed by the law of May 11, 2007, on Family Estate Management Companies (as amended) or by the Law of February 13, 2007, on Specialized Investment Funds (as amended) or by the Law of December 17, 2010, on Undertakings for Collective Investment (as amended) or by the law of July 23, 2016, on Reserved Alternative Investment Funds not having the exclusive purpose of investing in risk capital, is not subject to Luxembourg income tax; thus, neither dividends (and other payments) derived from shares held in a company nor capital gains realized on the sale or disposal, in any form whatsoever, of shares in a company, are taxable at the level of such resident corporate shareholders.

Resident individual shareholders

For resident individual shareholders, dividends derived from shares and capital gains realized on the sale of shares are, in principle, subject to income tax at the progressive ordinary rate (with a current effective marginal rate of up to 42%). Such income tax rate is increased by 7% for income not exceeding €150,000 for single taxpayers and €300,000 for couples taxed jointly, and by 9% for income above these amounts. In addition, a 1.4% dependence insurance contribution is due.

50% of the gross amount of dividends derived from shares may however be exempt from income tax, if the conditions laid down under Article 115 (15a) LITL, as described above, are complied with. In addition, a total lump-sum of €1,500 (which is doubled for taxpayers who are jointly taxable) is deductible from the total of dividends received during the tax year in order to determine the total taxable amount of investment income of the taxpayer.

Capital gains realized on the disposal of the shares by resident individual shareholders who act in the course of the management of their private wealth, will in principle only be taxable if said capital gains qualify either as speculative gains or as gains on a substantial participation. A disposal may include a sale, an exchange, a contribution or any other kind of alienation of shares. Capital gains are deemed to be speculative if the shares are disposed within six months after their acquisition or if their disposal precedes their acquisition. Speculative gains realized during the year that are equal to, or are greater than, €500 are subject to income tax at ordinary rates. A participation is deemed to be substantial where a resident individual shareholder holds, either alone or together with his spouse, his partner or minor children, directly or indirectly, at any time within the 5 years preceding the disposal, more than 10% of share capital of a collective entity. A shareholder is also deemed to alienate a substantial participation if such participation (i) has been acquired free of charge, within the 5 years preceding the transfer, and (ii) was constituting a substantial participation in the hands of the alienator (or the alienators in case of successive transfers free of charge within the same 5-year period). Capital gains realized on a substantial participation more than six months after the acquisition thereof may benefit from an allowance of up to €50,000 granted for a ten-year period (which is doubled for taxpayers who are jointly taxable). They are subject to income tax according to the half-global rate method (i.e., the average rate applicable to the total income is calculated according to progressive income tax rates and half of the average rate is applied to the capital gains realized on the substantial participation).

Capital gains realized on the disposal of the Company’s shares by resident individual shareholders, who act in the course of their professional or business activity, are subject to income tax at ordinary rates. Taxable gains are determined as being the difference between the price for which the shares have been disposed of and the lower of their cost or book value.

Non-resident shareholders

Non-resident shareholders (either individual or corporate) owning a non-substantial shareholding are exempt from capital gains taxes. Non-resident shareholders owning a substantial shareholding (more than 10% of share capital of a collective entity) are taxable in Luxembourg on a capital gain realized upon the disposal if at the date of the disposal the shareholding has been owned for not more than six months, unless the non-resident shareholder is resident in a treaty country and the treaty allocates the taxation right for the capital gain to the country of residence. In this latter case, no capital gains tax will be due by non-resident shareholder. Capital gains realized on the disposal of

shares by non-resident shareholders that have been owned for more than 6 months are not subject to Luxembourg income tax.

Net wealth tax

Whilst non-resident corporate taxpayers may only be subject to Net Wealth Tax (“NWT”) on the net assets attributable to a permanent establishment located in Luxembourg or on real estate assets located in Luxembourg, resident corporate taxpayers are in principle subject to NWT at the rate of 0.5% for net wealth up to €500 million and at 0.05% for net wealth exceeding this threshold, unless a double tax treaty provides for an exemption or the asset may benefit from the Luxembourg participation exemption regime. Net worth is referred to as the unitary value (valeur unitaire), as determined at 1 January of each year. The unitary value is basically calculated as the difference between (a) assets estimated at their fair market value and (b) liabilities vis-à-vis third parties, unless one of the exceptions mentioned below are satisfied.

A resident corporate shareholder will be subject to NWT on shares, except if (i) the shareholder is a securitization company governed by the Law of March 22, 2004, on Securitization (as amended) or an investment company in risk capital governed by the Law of June 15, 2004, on Venture Capital Vehicles (as amended) or a specialized investment fund governed by the Law of February 13, 2007, on Specialized Investment Funds (as amended) or a family wealth management company governed by the Law of May 11, 2007, on Family Estate Management Companies (as amended) or an undertaking for collective investment governed by the Law of December 17, 2010, on Undertakings for Collective Investment (as amended) or a pension-saving company as well as a pension-saving association, both governed by the Law of July 13, 2005 (as amended), or a reserved alternative investment fund governed by the law of July 23, 2016, or (ii) if the conditions mentioned above for the participation exemption regime on dividend income are met at the end of the previous year (except that no minimum holding period is required).

Effective until December 31, 2024, a resident corporate shareholder may further be subject to either a minimum NWT of €4,815 or to a progressive minimum net wealth tax from €535 to €32,100, which depends on the total assets on their balance sheet. The minimum net wealth tax of €4,815 will be applicable for a resident corporate shareholder, which has a minimum of 90% of fixed financial assets, transferable securities and cash at bank on its balance sheet, except if its accumulated fixed financial assets do not exceed €350,000, in which case it may benefit from a minimum net wealth tax of €535. Items (e.g., real estate properties or assets allocated to a permanent establishment) located in a treaty country, where the latter has the exclusive tax right, are not considered for the calculation of the 90% threshold.

Effective from January 1, 2025, the minimum NWT has been amended by the Law of 20 December 2024. The revised NWT rates will range from €535 to €4,815. From 2025 onward, the applicable threshold will be determined based on the taxpayer's total balance sheet rather than the composition of its assets. This amendment responds to the Constitutional Court's ruling on July 1, 2023, which declared the previous NWT unconstitutional due to its discriminatory effects among similarly situated taxpayers. The minimum NWT rates, effective from the fiscal year 2025, are (i) €535 for a balance sheet total up to and including €350,000; (ii) €1,605 for a balance sheet total exceeding €350,000 and up to and including €2 million; and (iii) €4,815 for a balance sheet total exceeding €2 million.

It is specified that the balance sheet used for calculating the Minimum NWT must be the closing balance sheet for the relevant tax year, in compliance with all corporate income tax provisions. Consequently, all figures must be derived from the commercial balance sheet, subject only to necessary revaluations required for CIT compliance.

Notwithstanding the above, shareholdings that qualify for the participation exemption and Luxembourg-situs real estate must be included in gross assets for this calculation. Conversely, foreign-situs real estate and other assets, such as those of a foreign branch whose income is excluded from the Luxembourg tax base under the provisions of a double tax treaty, shall not be included from the calculation of gross assets.

Despite the above mentioned exceptions, the minimum net wealth tax also applies if the resident corporate shareholder is a securitization company governed by the Law of March 22, 2004, on Securitization (as amended) or an investment company in risk capital governed by the Law of June 15, 2004, on Venture Capital Vehicles (as amended) or a pension-saving company as well as a pension-saving association, both governed by the Law of July 13, 2005 (as amended), or a reserved alternative investment fund having the exclusive purpose of investing in risk capital governed by the law of July 23, 2016.

The NWT charge for a given year can be avoided or reduced if a specific reserve, equal to five times the NWT to save, is created before the end of the subsequent tax year and maintained during the five following tax years. The net wealth tax reduction corresponds to one fifth of the reserve created, except that the maximum net wealth tax to be saved is limited to the corporate income tax amount due for the same tax year, including the employment fund surcharge, but before imputation of available tax credits.

Inheritance tax

Where a shareholder is a resident of Luxembourg for tax purposes at the time of his/her death, shares are included in his/her taxable estate for inheritance tax assessment purposes.

Gift tax

Gift tax may be due on a gift or donation of shares if recorded in a Luxembourg notarial deed or otherwise recorded in Luxembourg.

Registration taxes and stamp duties

In principle, neither the issuance of shares nor the disposal of shares is subject to Luxembourg registration tax or stamp duty.

However, a registration duty may be due (i) in the case where the deed acknowledging the issuance/disposal of shares is either attached (annexé) to a deed subject to a mandatory registration in Luxembourg (e.g., public deed) or lodged with a notary’s records (deposé au rang des minutes d’un notaire), or (ii) in case of a registration of such deed on a voluntary basis.

Material U.S. Federal Income Tax Considerations

The following is a description of material U.S. federal income tax consequences to the U.S. Holders described below of owning and disposing of our common shares. It does not describe all tax considerations that may be relevant to a particular person’s decision to hold common shares. This discussion applies only to a U.S. Holder that holds common shares as capital assets for U.S. federal income tax purposes. In addition, it does not describe all of the U.S. federal income tax consequences that may be relevant in light of the U.S. Holder’s particular circumstances, including alternative minimum tax consequences, the potential application of the provisions of the Internal Revenue Code of 1986, as amended (the “Code”) known as the Medicare contribution tax and tax consequences applicable to U.S. Holders subject to special rules, such as:

• certain financial institutions;

• dealers or traders in securities that use a mark-to-market method of tax accounting;

• persons holding common shares as part of a hedging transaction, straddle, wash sale, conversion transaction or other integrated transaction or persons entering into a constructive sale with respect to the common shares;

• persons whose functional currency for U.S. federal income tax purposes is not the U.S. dollar;

• entities classified as partnerships for U.S. federal income tax purposes;

• tax-exempt entities, “individual retirement accounts” or “Roth IRAs”;

• persons that own or are deemed to own ten percent or more of our shares, by vote or value;

• persons who acquired our common shares pursuant to the exercise of an employee stock option or otherwise as compensation; or

• persons holding common shares in connection with a trade or business conducted outside of the United States.

If an entity that is classified as a partnership for U.S. federal income tax purposes owns common shares, the U.S. federal income tax treatment of a partner will generally depend on the status of the partner and the activities of the partnership. Partnerships owning common shares and partners in such partnerships should consult their tax advisers as to the particular U.S. federal income tax consequences of owning and disposing of the common shares.

This discussion is based on the Code, administrative pronouncements, judicial decisions, final, temporary and proposed Treasury regulations, and the income tax treaty between Luxembourg and the United States (the “Treaty”) all as of the date hereof, any of which is subject to change or differing interpretations, possibly with retroactive effect.

A “U.S. Holder” is a person who, for U.S. federal income tax purposes, is a beneficial owner of our common shares and is:

• an individual who is a citizen or resident of the United States;

• a corporation, or other entity taxable as a corporation, created or organized in or under the laws of the United States, any state therein or the District of Columbia; or

• an estate or trust the income of which is subject to U.S. federal income taxation regardless of its source.

This discussion does not address the effects of any state, local or non-U.S. tax laws, or any U.S. federal taxes other than income taxes (such as U.S. federal estate or gift tax consequences). U.S. Holders should consult their tax advisers concerning the U.S. federal, state, local and non-U.S. tax consequences of owning and disposing of our common shares in their particular circumstances.

Treasury regulations that apply to taxable years beginning on or after December 28, 2021 may in some circumstances prohibit a U.S. person from claiming a foreign tax credit with respect to certain non-U.S. taxes that are not creditable under applicable income tax treaties. Accordingly, U.S. investors that are not eligible for Treaty benefits should consult their tax advisers regarding the creditability or deductibility of any Luxembourgish taxes imposed on dividends on, or dispositions of, common shares. This discussion does not apply to investors in this special situation.

Except as described below, this discussion assumes that we are not, and will not become, a passive foreign investment company (a “PFIC”) for any taxable year.

Taxation of Distributions

Distributions paid on common shares, other than certain pro rata distributions of common shares, will generally be treated as dividends to the extent paid out of our current or accumulated earnings and profits (as determined under U.S. federal income tax principles). Because we do not maintain calculations of our earnings and profits under U.S. federal income tax principles, we expect that distributions generally will be reported to U.S. Holders as dividends. Subject to applicable limitations, dividends paid by qualified foreign corporations to certain non corporate U.S. Holders are taxable at rates applicable to long-term capital gains. A foreign corporation is treated as a qualified foreign corporation with respect to dividends paid on stock that is readily tradable on a securities market in the United States, such as the Nasdaq Stock Market, where our common shares are traded. U.S. Holders should consult their tax advisers to determine whether the favorable rates will apply to dividends they receive and whether they are subject to any special rules that limit their ability to be taxed at this favorable rate.

Dividends will not be eligible for the dividends received deduction generally available to U.S. corporations under the Code. Dividends will be included in a U.S. Holder’s income on the date of receipt. The amount of any dividend income paid in euros will be the U.S. dollar amount calculated by reference to the exchange rate in effect on the date of actual or constructive receipt, regardless of whether the payment is in fact converted into U.S. dollars at that time. If the dividend is converted into U.S. dollars on the date of receipt, a U.S. Holder should not be required to recognize foreign currency gain or loss in respect of the dividend income. A U.S. Holder may have foreign currency gain or loss if the dividend is converted into U.S. dollars after the date of receipt.

Dividends will be foreign-source and will include any amount withheld by us in respect of Luxembourg income taxes. Subject to applicable limitations, some of which vary depending upon the U.S. Holder’s particular circumstances, non-refundable Luxembourg income taxes withheld from dividends at a rate not exceeding any applicable rate provided by the Treaty will be creditable against the U.S. Holder’s U.S. federal income tax liability. The rules governing foreign tax credits are complex and U.S. Holders should consult their tax advisers regarding the creditability of foreign taxes in their particular circumstances. In lieu of claiming a foreign tax credit, U.S. Holders may, at their election, deduct foreign taxes, including any Luxembourg income tax, in computing their taxable income, subject to generally applicable limitations under U.S. law. An election to deduct foreign taxes instead of claiming foreign tax credits applies to all foreign taxes paid or accrued in the taxable year.

Sale or Other Disposition of Common Shares

For U.S. federal income tax purposes, gain or loss realized on the sale or other disposition of common shares will be capital gain or loss, and will be long-term capital gain or loss if the U.S. Holder held the common shares for more than one year. The amount of the gain or loss will equal the difference between the U.S. Holder’s tax basis in the common shares disposed of and the amount realized on the disposition, in each case as determined in U.S. dollars. This gain or loss will generally be U.S.-source gain or loss for foreign tax credit purposes. The deductibility of capital losses is subject to limitations.

Passive Foreign Investment Company Rules

We believe that we were not a “passive foreign investment company” (a “PFIC”) for U.S. federal income tax purposes for our taxable year ended December 31, 2024. However, our PFIC status for any taxable year is an annual determination that depends on the composition of our income and assets and the market value of our assets, which may change from time to time. In addition, if we expand our lending activities in the future in any significant fashion, our risk of becoming a PFIC will increase. Accordingly, there can be no assurance that we will not be a PFIC for any taxable year. If we are a PFIC for any year during which a U.S. Holder holds common shares, we generally will continue to be treated as a PFIC with respect to that U.S. Holder for all succeeding years during which the U.S. Holder holds common shares, even if we cease to meet the threshold requirements for PFIC status.

If we are a PFIC for any taxable year during which a U.S. Holder holds common shares, gain recognized by a U.S. Holder on a sale or other disposition (including certain pledges) of the common shares will be allocated ratably over the U.S. Holder’s holding period for the common shares. The amounts allocated to the taxable year of the sale or other disposition and to any year before we became a PFIC will be taxed as ordinary income. The amount allocated to each other taxable year will be subject to tax at the highest rate in effect for individuals or corporations, as appropriate, for that taxable year, and an interest charge will be imposed on the resulting tax liability for each such year. Further, to the extent that any distributions received by a U.S. Holder on its common shares in a taxable year exceed 125% of the average of the annual distributions on the common shares received during the preceding three years or the U.S. Holder’s holding period, whichever is shorter, such distributions will be subject to taxation in the same manner. If we were a PFIC, certain elections (such as mark-to-market election) may be available that would result in alternative tax consequences of owning and disposing of the common shares.

In addition, if we are a PFIC or, with respect to a particular U.S. Holder, are treated as a PFIC for the taxable year in which we pay a dividend or for the prior taxable year, the preferential dividend rate discussed above with respect to dividends paid to certain non-corporate U.S. Holders will not apply.

If a U.S. Holder owns common shares during any year in which we are a PFIC, the U.S. Holder generally must file annual reports on an IRS Form 8621 (or any successor form) with respect to us, generally with the U.S. Holder’s federal income tax return for that year.

U.S. Holders should consult their tax advisers concerning the potential application of the PFIC rules.

Information Reporting and Backup Withholding

Payments of dividends and sales proceeds that are made within the United States or through certain U.S.-related financial intermediaries generally are subject to information reporting, and may be subject to backup withholding, unless (i) the U.S. Holder is a corporation or other exempt recipient or (ii) in the case of backup withholding, the U.S. Holder provides a correct taxpayer identification number and certifies that it is not subject to backup withholding.

The amount of any backup withholding from a payment to a U.S. Holder will be allowed as a credit against the holder’s U.S. federal income tax liability and may entitle it to a refund, provided that the required information is timely furnished to the IRS.

Certain U.S. Holders who are individuals or specified entities may be required to report information on their U.S. federal income tax returns relating to their ownership of our common shares, subject to certain exceptions (including an exception for common shares held in a financial account, in which case the account may be reportable if maintained by a non-U.S. financial institution).

U.S. Holders should consult their tax advisers regarding their reporting obligations with respect to their ownership and disposition of common shares.

Documents on Display

We are subject to the reporting and other informational requirements of the Exchange Act, except that as a foreign private issuer, we are not subject to the proxy rules or the short-swing profit disclosure rules of the Exchange Act, nor are we subject to the same requirements to file periodic reports and financial statements as U.S. companies whose securities are registered under the Exchange Act. In accordance with these statutory requirements, we file or furnish reports and other information with the SEC, which are available to the public through the SEC's website at www.sec.gov.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The following information should be read together with note D. Financial risk management to our audited consolidated financial statements included elsewhere in this Annual Report.

Financial risk management

Millicom regularly performs financial risk management assessments to identify major risks and to take the necessary steps to mitigate such risks. The principal market risks to which we are exposed are interest rate risk, foreign currency exchange risk and non-repatriation. The Millicom Group analyzes each of these financial risks individually as well as on an interconnected basis and defines and implements strategies to manage the economic impact on the Millicom Group’s performance in line with its Group Treasury Policy. The "Group Treasury Policy" (including treasury and financial risk management) is annually updated by the Millicom Group's Treasury function and presented to the Audit and Compliance Committee. This policy was last reviewed in November 2024.

As part of the financial risk management strategy, the Millicom Group sets some targets in place to address and monitor financial risks, which include the use of derivatives and natural hedging instruments, such as raising debt in local currency (where the Group targets to maintain at least 40% of its debt in local currency) and maintaining at least 75%/25% of debt with fixed interest rates. The Group also implements some hedging strategies related to operational expenditure/capital expenditure, where it can cover up to six months forward of operating costs and capital expenditure denominated in non-functional currencies through a rolling and layering strategy. Millicom’s financial risk management strategies may include the use of derivatives to the extent a market would exist in the jurisdictions where the Millicom Group operates. Millicom’s policy prohibits the use of such derivatives in the context of speculative trading. From time to time, Millicom enters into currency and interest rate swap contracts to manage its exposure to fluctuations in interest rates and currency fluctuations in accordance with its Group Treasury policy.

On December 31, 2024 and 2023, the fair value of derivatives held by the Millicom Group may be summarized as follows:


	December 31,
	2024	2023
	(U.S. dollars in millions)
Derivatives
Cash flow hedge derivatives - asset	—	6
Cash flow hedge derivatives - liability	(59)	(46)
Net derivative asset (liability)	(59)	(40)

Interest rate risk

Debt and financing issued at floating interest rates expose the Millicom Group to cash flow interest rate risk. Debt and financing issued at fixed interest rates expose the Millicom Group to fair value interest rate risk. The Millicom Group’s exposure to risk of changes in market interest rates relate to both of the above. The Millicom Group actively and periodically monitors interest rate risk and has implemented some internal targets within its strategy where it aims to maintain at least 75% of debt with fixed interest rates. The purpose of Millicom’s strategy is to achieve an optimal balance between cost of funding and volatility of financial results, while taking into account market conditions as well as our overall business strategy.

At December 31, 2024, approximately 84% of the Millicom Group’s borrowings are at a fixed rate of interest or for which variable rates have been swapped for fixed rates with interest rate swaps (2023: 80%). The table below summarizes our fixed rate debt and floating rate debt:

A 100 basis point fall or rise in market floating interest rates for all currencies in which the Group had borrowings at December 31, 2024 would increase or reduce profit before tax from continuing operations for the year by approximately $9 million (2023: $14 million).

Foreign currency risk

The Millicom Group is exposed to foreign exchange risk arising from various currency exposures in the countries in which it operates. Foreign exchange risk arises from future commercial transactions, recognized assets and liabilities and net investments in foreign operations. In the years ended December 31, 2024, 2023 and 2022, foreign currency exchange rate fluctuations resulted in a loss of $43 million, gain of $31 million and a loss of $84 million, respectively.

Millicom seeks to reduce its foreign currency exposure through a policy of matching, as far as possible, assets and liabilities denominated in foreign currencies, or entering into agreements that limit the risk of exposure to currency fluctuations against the U.S. dollar reporting currency. In some cases, Millicom may also borrow in U.S. dollars where it is either commercially more advantageous for joint ventures and subsidiaries to incur debt obligations in U.S. dollars or where U.S. dollar denominated borrowing is the only funding source available to a joint venture or subsidiary. In these circumstances, Millicom accepts the remaining currency risk associated with financing its joint ventures and subsidiaries, principally because of the relatively high cost of forward cover, when available, in the currencies in which the Millicom Group operates.

The following table summarizes debt denominated in U.S. dollars and other currencies at December 31, 2024 and 2023.


	2024	2023
	(U.S. dollars in millions)
December 31
Debt denominated in U.S. dollars	3,429	3,859
Debt denominated in currencies of the following countries:
Guatemala	496	640
Colombia	554	694
Bolivia	153	246
Paraguay	233	158
El Salvador(i)	71	174
Panama(i)	734	759
Luxembourg (COP denominated)	33	38
Costa Rica	113	110

Total debt denominated in other currencies	2,386	2,819
Total debt (ii)	5,815	6,678

(i) El Salvador's official unit of currency is the U.S. dollar, while Panama uses the U.S. dollar as legal tender. Our local debt in both countries is therefore denominated in U.S. dollars but presented as local currency (LCY).

(ii) Excluding vendor financing of $18 million in Colombia, due within one year, as of December 31, 2023.

At December 31, 2024, if the U.S. dollar had weakened/strengthened by 10% against the other functional currencies of our operations and all other variables held constant, then profit before tax from continuing operations would have increased/decreased by $8 million (2023: $25 million), mainly as a result of the conversion of the USD-denominated net debts in our operations with functional currencies other than the U.S. dollar.

Non-repatriation risk

Millicom’s operating subsidiaries and joint ventures generate most of the revenue of the Millicom Group and in the currency of the countries in which they operate. Millicom is therefore dependent on the ability of its subsidiaries and joint venture operations to transfer funds to the Company.

Foreign exchange controls exist in some of the countries in which Millicom Group companies operate, and some of these controls significantly restrict the ability of these operations to pay interest, dividends, technical service fees, royalties or repay loans by exporting cash, instruments of credit or securities in foreign currencies. In addition, existing foreign exchange controls may be strengthened in countries where the Millicom Group operates, or foreign exchange controls may be introduced in countries where the Millicom Group operates that do not currently impose such restrictions. If such events were to occur, the Company’s ability to receive funds from the operations could be restricted even further, which would impact the Company’s ability to make payments on its interest and loans or pay dividends to its shareholders. As a policy, all operations which do not face restrictions to deposit funds offshore and in hard currencies should do so for the surplus cash generated on a weekly basis. The Company and its subsidiaries make use of physical cash pooling arrangements in hard currencies to the extent permitted.

In addition, in some countries it may be difficult to convert large amounts of local currency into foreign currency because of limited foreign exchange markets. The practical effects of this may be time delays in accumulating significant amounts of foreign currency and exchange risk, which could have an adverse effect on the Millicom Group. This is a relatively rare case for the countries in which the Millicom Group operates.

Lastly, repatriation most often gives rise to taxation, which is evidenced in the amount of taxes paid by the Millicom Group relative to the Corporate Income Tax reported in its statement of income.

CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

As of December 31, 2024, MIC S.A., under the supervision and with the participation of the Millicom Group’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, performed an evaluation of the effectiveness of the Millicom Group’s disclosure controls and procedures. The Millicom Group’s disclosure controls and procedures are designed to ensure that information required to be disclosed under the Exchange Act is accumulated and communicated to the Millicom Group’s management to allow timely decisions regarding required disclosures. The Millicom Group’s management necessarily applied its judgment in assessing the costs and benefits of such controls and procedures, which by their nature can provide only reasonable assurance regarding management’s control objectives.

Based on this evaluation, the Company’s Chief Executive Officer and Chief Financial Officer concluded that as of December 31, 2024, the Millicom Group’s disclosure controls and procedures are effective at the reasonable assurance level for recording, processing, summarizing and reporting the information the Company is required to disclose in the reports it files under the Exchange Act within the time periods specified in the SEC's rules and forms.

Management’s Annual Report on Internal Control over Financial Reporting

The Millicom Group’s management is responsible for establishing and maintaining adequate internal control over financial reporting for the Group.

Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of the Group’s financial reporting as well as the preparation of consolidated financial statements for external reporting purposes in accordance with IFRS as issued by the International Accounting Standards Boards.

The Group’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Group; (2) provide reasonable assurance that transactions are recorded as necessary to permit the preparation of consolidated financial statements in accordance with IFRS, and that receipts and expenditures of the Group are being made only in accordance with authorizations of management and directors of the Group; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Group’s assets that could have a material effect on the Group’s consolidated financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements and, even when determined to be effective, can provide only reasonable assurance with respect to consolidated financial statements preparation and presentation. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with policies or procedures may deteriorate.

The Group’s management conducted an assessment of the effectiveness of the Group’s internal control over financial reporting as of December 31, 2024, based on the framework in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on its assessment, management believes that, as of December 31, 2024, the Group’s internal control over financial reporting is effective based on those criteria.

The Group’s internal control over financial reporting as of December 31, 2024 has been audited by KPMG LLP, the Group’s external independent registered public accounting firm, as stated in its report which follows.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of

Millicom International Cellular S.A.:

Opinion on Internal Control Over Financial Reporting

We have audited Millicom International Cellular S.A. and subsidiaries' (the Company) internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated statement of financial position of the Company as of December 31, 2024, the related consolidated statements of income, comprehensive income, changes in equity, and cash flows for the year ended December 31, 2024, and the related notes (collectively, the consolidated financial statements), and our report dated April 8, 2025 expressed an unqualified opinion on those consolidated financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

CORPORATE GOVERNANCE

Corporate Governance Statement and Framework

Corporate Governance Statement

As a foreign private issuer incorporated in Luxembourg with its principal listing on the Nasdaq Global Select Market, Millicom follows the laws of the Grand Duchy of Luxembourg, its "home country" for corporate governance practices, in lieu of the provisions of the Nasdaq Stock Market's Marketplace Rule 5600 series. In particular, the Nasdaq Stock Market's rules:

(i) provide for a quorum of no less than 33 1/3% of Millicom's outstanding shares, but Millicom's Articles of Association provide that no quorum is required for ordinary meetings (other than in respect of general meetings convened for the first time in relation to amendments to the Articles of Association);

(ii) provide for the involvement of independent directors in the selection of director nominees, but Millicom permits its director nominations committee to be comprised of shareholder representatives;

(iii) require each Compensation Committee member to be an independent director for purposes of the Nasdaq Stock Market’s Marketplace Rule 5605(d)(2). However, to preserve greater flexibility in who may be appointed to the Compensation and Talent Committee, Millicom does not require the Compensation and Talent Committee to be comprised solely of directors who qualify as independent for such purposes;

(iv) require listed companies to have regularly scheduled meetings at which only independent directors are present, but Millicom does not impose such a requirement;

(v) require third-party compensation disclosure, but Millicom does not disclose third-party compensation provided to its directors or director nominees; and

(vi) require independent director oversight of director nominations, but Millicom allows its nomination committee to be appointed by the Company’s major shareholders and not a committee of the Board of Directors.

In addition, we may opt out of shareholder approval requirements for the issuance of securities in connection with certain events such as the acquisition of stock or assets of another company, the establishment of or amendments to equity-based compensation plans for employees, a change of control of us and certain private placements. To this extent, our practice will vary from the requirements of Nasdaq Listing Rules, which generally require an issuer to obtain shareholder approval for the issuance of securities in connection with such events.

Corporate Governance Framework

Articles of Association

Millicom International Cellular S.A. (“Millicom” or the “Company”) is a public limited liability company (société anonyme) governed by the Luxembourg Law of August 10, 1915, on Commercial Companies (as amended). The Company was incorporated on June 16, 1992, and registered with the Luxembourg Trade and Companies’ Register (Registre du Commerce et des Sociétés de Luxembourg) under number B 40 630. The Millicom Group comprises Millicom and its subsidiaries, joint ventures and associates. The Articles of Association of MIC S.A. define its purpose inter alia as follows: “... to engage in all transactions pertaining directly or indirectly to the acquisition and holding of participating interests, in any form whatsoever, in any Luxembourg or foreign business enterprise, including but not limited to, the administration, management, control and development of any such enterprise." The valid Articles of Association are filed herewith as Exhibit 1.1.

MIC S.A. has only one class of shares, common shares. Each share entitles its holder to: one vote at the general meeting of shareholders; receive dividends when such distributions are decided (subject as well to restrictions in the agreements governing our indebtedness); and share in any surplus left after the payment of all the creditors in the event of liquidation. There is a preferential subscription right pursuant to Luxembourg corporate law under any share or rights issue for cash, unless the Board of Directors, within the limits specified in the Articles of Association, or an extraordinary general meeting of shareholders, as the case may be, restricts the exercise thereof. The Company's Articles of Association do not impose any restrictions on the transfer of shares. MIC S.A. shares are not subject to any sinking fund provision and as all of the issued shares in MIC S.A.’s capital are fully paid up, none of MIC S.A.’s shareholders are liable for further capital calls. Following Luxembourg law, any change to the rights attached to the shares of MIC S.A. require an amendment of the Company’s Articles of Association through the approval of shareholders at an extraordinary shareholders’ meeting duly convened and held before a Luxembourg notary, with a two-thirds majority vote of the shares represented at the meeting. Any increase to the obligations attached to shares may be adopted only with the unanimous consent of all shareholders.

The Articles of Association provide for the possibility and set out the terms for the repurchase by MIC S.A. of its own shares, which repurchase must be approved in accordance with applicable law and the rules of any exchange on which MIC S.A.’s shares are listed.

An annual share repurchase plan was approved at our 2024 AGM (the "2024 Authorization") that authorized the Board of Directors, at any time between May 23, 2024 and the date of the 2025 AGM, provided the required levels of distributable reserves are met by MIC S.A. at that time, to engage in a share repurchase plan of MIC S.A.’s common shares to be carried out for all purposes allowed or which would become authorized by the laws and regulations in force, and in particular the Luxembourg law of August 10, 1915 on commercial companies, as amended (the “Share Repurchase Plan”) by using its available cash reserves.

The maximum number of common shares that may be acquired may not exceed ten percent (10%) of Millicom's outstanding share capital as of the date when the start of a share repurchase program is announced by press release. The maximum number of common shares includes repurchases of common shares represented by SDRs prior to the termination of the Company's SDR program on March 17, 2025.

For shares repurchased on a regulated market where the shares are traded, the price per share shall be within the registered interval for the share price prevailing at any time (the so called spread), that is, the interval between the highest buying rate and the lowest selling rate of the shares on the market on which the purchases are made. For any other shares repurchased, the price per share may not exceed 110% of the most recent closing trading price of the shares on the Nasdaq Stock Market in the U.S., provided that the minimum repurchase price is above SEK 50 (or USD equivalent).

Under the 2024 Authorization, the Board announced on November 29, 2024 a share repurchase program for up to $150 million of Millicom's shares. The purpose of the share repurchase program is to reduce the capital of Millicom by distributing funds to the shareholders, thus enhancing shareholder value, and to meet obligations under Millicom’s share-based incentive plans or other compensation programs. The share repurchase program is managed by a brokerage firm which makes trading decisions regarding the timing and quantity of the purchases, independently of Millicom, based on the framework agreed at inception. The share repurchase program is subject to the following conditions:

–Repurchases may take place during the period between December 9, 2024 and May 21, 2025.

–The maximum level of SDRs and shares that may be repurchased will be the lower of $150 million (approximately SEK 1.65 billion) in aggregate purchase price, or 17,200,000 SDRs / shares (the latter corresponding to approximately 10% of Millicom’s share capital, which is the maximum number allowed under the 2024 Authorization).

–Payment for the repurchases will be made in cash.

–SDRs and shares may be repurchased on Nasdaq Stockholm or the Nasdaq Global Select Market, respectively, at a price per share within the registered interval for the share price prevailing at any time (the spread), that is, the interval between the highest buying price and the lowest selling price on the regulated market where the purchases are made.

–The repurchased SDRs and shares will ultimately be transferred to employees of the Group in connection with any existing or future share-based incentive plan or be cancelled, as the case may be.

In addition to repurchases under the share repurchase program described above, but with the same purpose, Millicom effectuated separate repurchases to the extent permitted under the European Market Abuse Regulation and other applicable rules pursuant to the Authorization and before the commencement of repurchases under the share repurchase program.

Due to Swedish regulatory considerations, prior to March 2, 2025, Millicom did not repurchase SDRs or common shares at a price above USD 25.75 or the equivalent amount in SEK (such price being the increased offer price that Atlas Luxco S.à r.l offered to holders of SDRs and common shares in its tender offer for Millicom’s SDRs and common shares in 2024).

Shareholders’ Meetings

General meetings of shareholders are convened by convening notice published in the Luxembourg Official Gazette (Journal des Publications, Recueil Electronique des Sociétés et Associations), in a Luxembourg newspaper, in short version in the Swedish newspaper SvD (until March 17, 2025), as a press release and on the Millicom website. According to article 18 of the Articles of Association of MIC S.A., the Board of Directors determines in the convening notice the formalities to be observed by each shareholder for admission to the AGM. An AGM must be convened every year within six months of the end of the financial year, at the registered office of the Company or any other place in Luxembourg as may be specified in the convening notice. Other meetings can be convened as necessary.

Limitation on Securities Ownership

There are no limitations imposed under Luxembourg law or the Articles of Association on the rights of non-resident or foreign entities to own shares of the Company or to hold or exercise voting rights on shares of the Company.

Change of Control

There are no provisions in the Articles of Association of the Company that would have the effect of delaying, deferring or preventing a change in control of MIC S.A. and that would operate only with respect to a merger, acquisition or corporate restructuring involving the Company, or any of its subsidiaries.

Disclosure of Shareholder Ownership

Until March 17, 2025, as required by the Luxembourg law on transparency obligations of January 11, 2008, as amended (the “Transparency Law”), a shareholder who acquired or disposed of shares, including depositary receipts representing shares in the Company’s capital had to notify the Company and the Commission de Surveillance du Secteur Financier of the proportion of shares held by the relevant person as a result of the acquisition or disposal, where that proportion reached, exceeded or fell below the thresholds referred to in the Transparency Law. As per the Transparency Law, the above also applied to the mere entitlement to acquire or to dispose of, or to exercise, voting rights in any of the cases referred to in the Transparency Law. This ownership disclosure is no longer required as a result of the delisting from Nasdaq Stockholm.

Background

Millicom’s shares have been listed on the Nasdaq Global Select Market in the United States since January 9, 2019. Until March 17, 2025, Millicom's shares were also listed on Nasdaq Stockholm in the form of Swedish Depository Receipts. The delisting of the SDRs from Nasdaq Stockholm was approved on March 3, 2025 and became effective on March 17, 2025.

Until March 17, 2025, Millicom’s Corporate Governance Framework was primarily based on the following legislation, principles and regulations:


Publication	Authority	Philosophy
Swedish Code of Corporate Governance (until March 17, 2025)	Guiding Principles	Comply or Explain
Luxembourg Law	Legislation	Comply
EU Directives and Regulations	Legislation	Comply
Nordic Main Market Rulebook for Issuers of Shares (until March 17, 2025)	Regulation	Comply
Nasdaq Stock Market Rules	Regulation	Comply
U.S. Securities Laws	Regulation	Comply
Good Stock Market Practice	Guiding Principles	Corporate Citizenship

Within these frameworks, Millicom's Board develops and monitors internal guidelines and practices, as further described below, to ensure the quality and transparency of Millicom's corporate governance.

Swedish Corporate Governance Code

Until the delisting of its SDRs from Nasdaq Stockholm on March 17, 2025, Millicom followed the Swedish Corporate Governance Code (“Swedish Code”), which promoted good corporate governance to ensure companies are run sustainably, responsibly and efficiently. The Code, which is available on the website of the Swedish Corporate Governance Board: https://bolagsstyrning.se, complements mandatory laws and regulations and sets best practices that go beyond regulatory requirements. The Swedish Corporate Governance Board opted for self-regulation, and adopted a “comply or explain” philosophy. Therefore, companies may deviate from specific provisions, as long as they disclose the deviation and explain why they chose a different solution that is more suitable for their size and specific circumstances.

Compliance with Applicable Stock Exchange Rules

None of Nasdaq Stockholm’s Disciplinary Committee, the Swedish Securities Council or the Nasdaq Stock Market reported any infringement of applicable stock exchange rules or breach of good practice on the securities market by Millicom in 2024.

Corporate Governance Structure

Millicom' s Corporate Governance structure comprises the following three levels:

1.Shareholders and representatives of shareholders (see "—Shareholders and Representation of Shareholders" below).

2.The Board of Directors and Committees appointed by the Board (see "—Board Governance" below).

3.The Group Leadership Team, and their primary governance functions (see "—Group Leadership Team" below).

Shareholders and Representation of Shareholders

Shareholders and Shareholders’ Meeting

The shareholders’ meeting is Millicom's highest decision-making body and a forum for shareholders to voice their opinions. Each shareholder has the right to participate in the shareholders’ meeting and to cast one vote for every share. Shareholders unable to attend in person may exercise their rights by proxy or vote in writing (by way of proxies).

Millicom’s Articles of Association set the Annual General Meeting of Shareholders (“AGM”) to be held in Luxembourg within six months of the close of the financial year.

Unless otherwise required under Luxembourg Law, an extraordinary general meeting ("EGM") must be convened to amend the Articles of Association.

At the 2024 AGM, held in Luxembourg on May 23, 2024, shareholders approved all the resolutions proposed by the Board and Nomination Committee, including the following key items:

•the annual accounts and the consolidated accounts for the year ended December 31, 2023;

100

•the allocation of the profit of approximately $7,560,803 million of the 2023 results to the legal reserve, and the remaining $337,314,147 to unappropriated net profits to be carried forward;

•the discharge of all current and former Millicom Directors who served at any point in time during the financial year ended December 31, 2023, for the performance of their mandates;

•the establishment of the number of Directors at nine (9) and election of the Board members and Chair of the Board (see "—Board Governance—Board Profile: Skills and Experience);

•the election of KPMG as Millicom's external auditor;

•the remuneration to the Board members and external auditor;

•the instruction to the Nomination Committee;

•the share repurchase plan;

•the 2023 Remuneration Report;

•the senior management remuneration policy; and

•the share-based incentive plans for Millicom employees.

On May 23, 2024, an EGM was held to (i) to remove the casting vote of the Chair of the Board in the event of a tie provided by article 444-4 (2) of the Luxembourg law of August 10, 1915 on commercial companies and add a sentence to paragraph 7 of article 8 of Millicom’s articles of association expressly stating that the Chair of the Board does not have a casting vote in the event of a tie, (ii) to adopt inclusive language and change the definition from “Chairman” to “Chair” of the Board, and to amend articles 7, 8, 9 and 21 of Millicom’s articles of association accordingly, and further amend the second sentence of Article 19 of Millicom’s articles of association to refer to the “chair of the annual general meeting,” and (iii) to fully restate the Company’s articles of association to incorporate the amendments to the Company’s articles of association approved in the EGM.

Major Shareholders

To the extent known to the Company, it is neither directly nor indirectly owned or controlled by another corporation, any government, or any other person. In addition, there are no arrangements, known to the Company, the operation of which may result in a change in its control in the future.

The table below sets out beneficial ownership of our common shares (directly), par value $1.50 each, by each person who beneficially owned more than 5% of our common shares.


Name of Shareholder	Common Shares	Percentage of Share Capital
Niel Family Group (1)	70,470,018	41.88	%
Dodge & Cox (2)	8,674,932	5.1	%

(1) Information herein is based upon a Schedule 13D/A (amendment No. 19) filed with the SEC on March 17, 2025 by Atlas S.A.S. ("Atlas"), Atlas Investissement S.A.S. ("Atlas Investissement"), Iliad Holding S.A.S. ("Iliad Holding") and Xavier Niel, Jules Niel, John Niel and Elisa Niel (collectively, the "Atlas Holders"). The Atlas Holders held 70,470,018 common shares (approximately 41.88% of common shares outstanding) as of March 17, 2025. Atlas Investissement , as the controlling shareholder of Atlas, may be deemed to have shared beneficial ownership over the shares beneficially owned by Atlas. Iliad Holding, as the controlling shareholder of Atlas Investissement, may be deemed to have shared beneficial ownership over the shares beneficially owned by Atlas and Atlas Investissement. Xavier Niel, the President of Iliad Holding, Jules Niel, John Niel, Elisa Niel and Joseph Niel (together, the "Niel Family") may be deemed to have shared beneficial ownership over the shares beneficially owned by Atlas, Atlas Investissement and Iliad Holding. Further, in January 2025, Maxime Lombardini received 11 Atlas shares, Pierre-Emmanuel Durand received 11 Atlas shares and Jules Niel received 2 Atlas shares as compensation.

(2) Information herein is based upon a Schedule 13G/A filed with the SEC on February 13, 2024.

Except as otherwise indicated, the holders listed above (“holders”) have sole voting and investment power with respect to all shares beneficially owned by them. The holders have the same voting rights as all other holders of MIC S.A. common shares. For purposes of this table, a person or group of persons is deemed to have “beneficial ownership” of any shares as of a given date which such person or group of persons has the right to acquire within 60 days after such date. For purposes of computing the percentage of outstanding shares held by the holders on a given date, any security which such holder has the right to acquire within 60 days after such date (including shares which may be

101

acquired upon exercise of vested portions of share options) is deemed to be outstanding, but is not deemed to be outstanding for the purpose of computing the percentage ownership of any other person.

Pursuant to a Tender Offer Statement and Rule 13e-3 Transaction Statement filed under the cover of Schedule TO with the SEC on July 1, 2024, Atlas Luxco S.à r.l. (renamed Atlas S.A.S. in November 2024) made an offer to purchase all of the issued and outstanding common shares (including common shares represented by SDRs) of the Company (the "Tender Offer"). As a result of the Tender Offer, Atlas Luxco S.à r.l. increased its shareholding in the Company by approximately 10% to 40.37%.

Based on the SDR ownership reported by Euroclear Sweden AB, as of December 31, 2024, there were 1,402 record holders of SDRs in the United States that held 26,631,451 SDRs (representing 15.47% of the outstanding share capital as of such date). According to the records maintained by Broadridge Corporate Issuer Solutions, Inc., as of December 31, 2024, there were 66 record holders of common shares in the United States that held 87,938,275 common shares (representing 51.10% of the outstanding share capital as of such date). Cede & Co., the nominee of the Depository Trust Company, was the registered holder of 87,930,974 of such shares, which include 69,268,046 shares held by Atlas (representing 40.25% of the outstanding share capital as of such date). However, these figures may not be an accurate representation of the number of beneficial holders nor their actual location because most of the common shares and SDRs were held for the account of brokers or other nominees.

Nomination Committee

Millicom's prior Nomination Committee, which was elected in October 2023 and served until the appointment of a new Committee in October 2024, was composed of:

The Nomination Committee is appointed by the largest shareholders of Millicom. It is not a Board committee. Its role is to propose resolutions regarding electoral and remuneration issues to the shareholders’ meeting in a manner that promotes the common interest of all shareholders, regardless of how they are appointed. Nomination Committee members' terms of office typically begin at the time of the announcement of the interim report (covering the period from January to September of each year) and end when a new Nomination Committee is formed.

Under the terms of the Nomination Committee procedure, the committee consists of (i) three members appointed by the largest shareholders as of the last business day of June 2024 and (ii) the Company's Chair of the Board.

The Company's Articles of Association stipulate that the Nomination Committee rules and procedures of the Swedish Code of Corporate Governance shall be applied for the election of Directors to the Company's Board of Directors, as long as such compliance does not conflict with applicable mandatory law, applicable regulation or the mandatory rules of any stock exchange on which the Company’s shares are listed.

Nomination Committee proposals to the AGM include, among others:

•Election and remuneration of Directors of the Board and the Chair of the Board

•Appointment and remuneration of the external auditor

•Proposal of the Chair of the AGM

Promoting Board Diversity

Millicom’s Nomination Committee recognizes the importance of diversity for promoting strong corporate governance, competitive advantage and effective decision-making. The Nomination Committee is responsible for determining the appropriate skills, perspectives and experiences required of Board candidates based on the Company’s strategic needs and the current Board composition. This determination will include knowledge, experience and skills in areas that are critical to understanding the Company and its business; richness of views brought by different personal attributes, such as gender, race, age and nationality; other personal characteristics, such as integrity and judgment; and candidates’ commitment to the boards of other publicly held companies.

In its work, the Nomination Committee applied rule 4.1 of the Swedish Corporate Governance Code as its diversity policy.

Board Governance

Written charters set out the objectives, limits of authority, organization and roles and responsibilities of the Board and each of its committees.

Board of Directors and Board Committees

The Chair convenes the Board and leads its work. The Chair is accountable to the Board and acts as a direct liaison between the Board and the management of the Company through the CEO. Meeting agendas are set with the CEO, and the Chair communicates Board decisions where appropriate.

Role of the Board

103

The Board is responsible for approving Millicom’s strategy, financial objectives and operating plans, and for oversight of governance. The Board also plans for succession of the CEO and reviews other senior management positions.

As set forth in the Company’s Articles of Association, the Board must be composed of at least six members. The 2024 AGM set the number of Directors at nine, comprising a Chair, and eight members. On September 19, 2024, Mauricio Ramos stepped down as Chair of the Board and Maxime Lombardini assumed the role of Non-Executive Interim Chair. As a result, the number of members of the Board was reduced from nine to eight.

Additionally, Thomas Reynaud and Aude Durand stepped down from their roles as members of the Millicom Board, while Jules Niel and Pierre-Emmanuel Durand were appointed as interim members of the Board on September 24, 2024, until the next annual general meeting of shareholders.

The Board selects the CEO, who is charged with daily management of the Company and its business. The CEO is responsible for recruiting the senior management of the Company. The Board reviews plans for key senior management positions; supervises, supports and empowers the senior management team; and monitors senior managers' performance. In accordance with the Swedish Code, the division of work between the Board and the CEO was set forth in “The Rules of Procedure, Instructions to the CEO and Reporting Instructions”.

Further details on the roles and activities of the various committees, as well as their responsibilities and activities, appear later in this section.

Powers and Limitations of the Board

Borrowing powers: The Board has unrestricted borrowing powers on behalf of, and for the benefit of, Millicom.

Time and age limit: No age limit exists for being a director of Millicom. Directors' mandates can be for a maximum of six years before either being re-elected or ending their service. There are no restrictions on the maximum continuous periods that a director can serve. The current directors have been elected for a term starting on the date of the 2024 AGM and ending on the date of the 2025 AGM (i.e., for approximately one year).

Restrictions on voting: No contract or other transaction between the Company and any other person shall be affected or invalidated by the fact that any director, officer or employee of the Company has a personal interest in—or is a director, officer or employee of—such other person. However, the following conditions apply:

•The contract or transaction must be negotiated on an arm’s-length basis on terms no less favorable to the Company than could have been obtained from an unrelated third party; in the case of a director, he or she shall inform the Chair of his or her conflict of interest and abstain from deliberating and voting on any matters that pertain to such contract or transaction at any meeting of the Board.

•Any such personal interest shall be fully disclosed to the Company by the relevant director, officer or employee and, to the extent a director is involved, to the next general meeting of shareholders.

•Director's service agreements: None of MIC S.A's current directors have entered into service agreements with the Millicom Group or any of its subsidiaries providing for benefits upon termination of their respective directorships.

Share Ownership Requirements

Directors are not required to be shareholders of the Company. Share ownership of directors is included in the director biographies set out on the following pages. Directors, excluding shares beneficially owned by Jules Niel, collectively own less than 1% of the Company's outstanding shares as of December 31, 2024.

Insider Trading Policy

The Company has an insider trading policy governing the purchase, sale and other dispositions of our securities by directors, senior management and employees that are reasonably designed to promote compliance with applicable insider trading laws, rules and regulations, and any listing standards applicable to the Company. The insider trading policy is included as Exhibit 11.1 to this Annual Report.

Roles

Chair of the Board

104

The Chair is elected at the AGM. If the Chair relinquishes the position during the mandate period, the Board elects a new Chair from among its members to serve until the end of the next AGM. The Board Chair convenes the Board and leads its work, coordinates with the CEO to set the meeting agendas and serves as the Board's liaison to the CEO between meetings.

Deputy Chair of the Board

If elected by the Board, the Deputy Chair acts as a sounding board and provides support for the Chair. The Deputy Chair convenes Board meetings in accordance with the Company’s Articles of Association and leads the Board's work in the event the Chair is unavailable or is excused from a Board meeting. The Deputy Chair may act as an intermediary in any conflicts among Board members or between the Chair and the CEO. The Board can designate additional roles and responsibilities of the Deputy Chair.

Corporate Secretary

The Corporate Secretary is appointed by the Board to ensure that Board members have the proper advice and resources for performing their duties. The Corporate Secretary is also responsible for organizing and coordinating Board and committee meetings and ensuring that the minutes of those meetings reflect the proper exercising of Board duties.

The Corporate Secretary is also a confidante and resource to the Board and senior management, providing advice on governance, Board responsibilities and logistics.

Chief Executive Officer (CEO)

The CEO leads the development and execution of the Company’s strategy with a view to creating shareholder value and enacting the Company's purpose. The CEO is responsible for day-to-day activities and management decisions, both operating and financial. The CEO is a liaison between the Board and management and communicates to the Board on behalf of management.

The CEO also leads Millicom's communications with shareholders, employees, government authorities, other stakeholders and the public.

Board Membership, Balance and Independence

The Nomination Committee and the Board periodically review the size, balance and diversity of the Board to determine whether any changes are appropriate.

At the AGM, held annually within six months of the end of the financial year, or at any other general meeting, shareholders may vote for or against the directors proposed by the Nomination Committee. One or several shareholders representing, individually or collectively, at least 10% of the share capital of Millicom may reserve the right to add one or more additional items to the agenda of the AGM and/or EGM.

The Board has adopted the qualification guidelines of an “independent director” as defined by the Swedish Code, and with consideration of the specific independence requirements within the Nasdaq Stock Market rules. A Director’s independence is determined by a general assessment of the Company or its executive management based on the Board's independence criteria. All of the 8 directors (Chair and 7 members) are non-executive and independent from the Company and its executive management, with three of them being affiliated with the largest shareholder (Maxime Lombardini, Jules Niel and Pierre-Emmanuel Durand) as of December 31, 2024.

Induction and Training

Millicom provides incoming Board members with information on their roles and responsibilities, the Board's operating procedures and Millicom’s business and industry. We provide access to governance documents, policies and procedures; meeting materials; and Company information through a secure online tool, in meetings set with the Group Leadership Team, and through ongoing dissemination of information.

Millicom provides training on topics such as anti-bribery and corruption, ethics, independence and insider trading. In addition, the Board regularly receives detailed reports on specific areas that support directors' understanding of Millicom’s business and operating environment.

In 2024, the directors participated in a visit to Millicom’s operations in Panama to learn about the characteristics of the local market, meet with the general managers of all Tigo operations, and interact with local management.

Board Effectiveness

The Board conducts an annual performance review process, wherein each Board member’s personal performance is also reviewed. This involves assessing Board and committee actions and activities against the Board’s mandate, as determined in the Board Charter, and the mandates of its various committees.

The Board used a questionnaire to assess its performance during 2024 against the Board's key duties, its composition and processes, and the performance of individual Board members. The results of the evaluation were presented to the Nomination Committee. The Nomination Committee decided that it was not necessary to engage an international consultancy firm to assist in an assessment of the composition of the Board for the proposals to the AGM 2025.

Board Committees

The Board is supported by committees (Audit and Compliance Committee and Compensation and Talent Committee) that work on behalf of the Board within their respective areas of responsibility. From time to time, the Board delegates authority to an “ad hoc” work group so that it may resolve a specific matter on its own without having to go before the full Board for approval.

I. Audit and Compliance Committee

Letter from the Chair of the Audit and Compliance Committee

I am pleased to present the Audit and Compliance Committee’s report for 2024. We convened six formal meetings during the financial year in order to satisfy our established set of responsibilities.

In 2024, the Company implemented actions to drive an increase in annual equity free cash flow generation, demonstrating resilience and paving the way for a strong 2025. These actions, alongside with evolving technological advancements and new regulatory requirements, such as Environmental, Social and Governance (ESG) disclosures, cybersecurity, among others—presented both opportunities and challenges that shaped the agenda of the Audit and Compliance Committee throughout the year.

Compliance Related topics

In 2024, we continued to evolve the ethics and compliance program to better assist employees in doing the right thing the right way, while further expanding the program's reach. As such, we continued enhancing our three strategic focus points: embed and entrench, communication, and data analytics. With compliance integrated within the Company's business processes, compliance teams are better able to detect and mitigate any potential risks in real time. Additionally, the compliance function disseminated its messages in conjunction with other departments in a clear and understandable manner, with everyone in the organization apprised of both risks and controls that are in place. Similarly, we used data collected on our and other functions' platforms to develop action plans and attack root causes. Importantly, upon embarking on his new role, our CEO immediately set a strong compliance tone at the top by directly asking the organization, as a whole, to achieve results the right way.

In focusing on the most pressing risks in 2024, we continued reinforcing the main elements of our compliance program, including our annual training for the entire Company. The training covered, among other topics, our Code of Conduct, our Speak Up campaign, and our Anti-corruption Policy. The training campaign this year was highly

112

interactive and factually based. Additionally, in 2024, we reviewed our Conflicts of Interest policy. The revised policy aims to mitigate the current risk landscape, adopt best practices across the board, and complement the tone from the top.

Audit Related topics

The Audit and Compliance Committee engaged in risk oversight of critical areas like ESG, cybersecurity and other external threats. Further, our overarching objectives included ensuring the integrity of the Group’s financial reporting and that appropriate accounting judgments were made, assessing the external auditor's effectiveness, and overseeing the status of the internal control environment. In addition to tracking important regulatory developments in financial reporting, the committee monitored tax obligations, new debt issuance and refinancing activities, as well as the evolution of Millicom’s risk management programs.

Our Internal Audit Team supported the committee by harmonizing their plans and assurance activities with the evolving risk profile. These activities generated relevant recommendations aimed at enhancing the control posture of the Company.

I wish to extend my appreciation to my colleagues for their support of and commitment to the activities of the committee.

Appointment and Role of the Audit and Compliance Committee

Millicom's Directors have established an Audit and Compliance Committee that convenes at least four times a year and comprises a minimum of two directors. The Audit and Compliance Committee is composed solely of Non-Executive Directors, all of whom were independent Directors in 2024. Members are appointed to ensure there is a mixture of relevant experience in both finance and broader commercial matters. The Board is confident that the collective experience of the members enables them to act as an effective Audit and Compliance Committee. The Audit and Compliance Committee is also satisfied that it has the expertise and resources available to fulfill its responsibilities.

This committee has responsibility to assist the Board in its responsibility for the robustness, integrity and effectiveness of financial reporting, risk management, internal controls, cybersecurity program, internal audit and external audit process, as well as compliance with related laws and regulations; and to oversee the Company’s compliance program, standards of business conduct and related investigations, and to monitor the Company’s actions and resources in these areas. Millicom’s Audit and Compliance Committee reports on and makes recommendations to the full Board regarding the Group’s compliance programs and standards of business conduct. The ultimate responsibility for reviewing and approving Millicom’s Annual Report and accounts remains with the Board.

The Chief Executive Officer, Chief Financial Officer, Chief Accounting Officer, VP Internal Audit & Enterprise Risk Management, Head of Business Controls, Chief Legal and Compliance Officer, Chief Technology and Information Officer, Chief External Affairs Officer and representatives from the Company's external auditor KPMG are invited to

attend committee meetings. The Secretary of the committee is the Group's Company Secretary. The Audit and Compliance Committee Chair prepares the meeting agenda in conjunction with the Chief Financial Officer and Chief Legal and Compliance Officer. Regular private sessions are held, attended only by Audit and Compliance Committee members and the external auditor, to provide an opportunity for open dialogue without management present. The Group Leadership Team are actively involved in fostering a culture of ethics and compliance from the top across all our lines of business.

At each regularly scheduled meeting, the Audit and Compliance Committee receives reports from the Chief Financial Officer, the external auditor, and the head of Internal Audit & Enterprise Risk Management and Business Controls. Additional reports are submitted by other officers of the Company as required. The Audit and Compliance Committee received the required information from the external auditor in accordance with Luxembourg regulations.

Financial reporting

The Audit and Compliance Committee reviewed earnings releases and financial statements for each quarter. Comprehensive reports from management and the external auditors highlighted the significant judgmental accounting issues for the attention of the committee. Reporting and disclosure topics under both EU and U.S. listing requirements were addressed. To assist with all matters related to earnings releases, financial statements and other market disclosures, Millicom has a Management Disclosure Committee composed of senior management from Finance, Legal and External Affairs as and when required. The Disclosure Committee identifies and considers disclosure matters in market releases, including releases that may contain material financial information.

External Auditor

Effectiveness

The quality and effectiveness of the external audit matter greatly to the Audit and Compliance Committee. A detailed audit plan outlining the key risks and proposed geographical coverage is prepared and discussed with the Audit and Compliance Committee at the start of each annual audit cycle. The committee assessed audit quality by referring to the standard of the reports received, the caliber of senior members of the audit team and the depth of inquiry and discussions with executive management, in addition to management feedback provided to the Audit and Compliance Committee. This feedback allows the committee to monitor and assess the performance of the external auditor as part of a recommendation to the Board regarding the auditor's appointment.

Independence

The Audit and Compliance Committee has policies to maintain the independence of the external auditor and to govern the provision of audit and non-audit services. The policies and approval process of non-audit services and audit-related services comply with SEC independence rules and with the latest EU and local regulations. Under these rules, the Audit and Compliance Committee pre-approves a list of services that can be rendered by the audit firm. If services to be rendered are pre-approved in nature, management can approve them when requested (following an established authority matrix) and present them to the Audit and Compliance Committee on a quarterly basis for formal approval. If services to be rendered are not pre-approved, they should be pre-approved by the Chair of the Audit and Compliance Committee when requested and then submitted to the next full Audit and Compliance Committee for formal approval. A schedule of all non-audit services with the external auditor is reviewed at each meeting.

For the year ended December 31, 2024, the Audit and Compliance Committee approved fees for audit and audit-related services of $4.4 million, together with fees for non-audit work of $0.2 million.

Risk Management and Internal Audit

Risk Management

The Audit and Compliance Committee received regular reports on the Group’s risk management framework and process from the Management Risk Committee, as well as reports on the evolution of significant risks at both operational and Group levels and related mitigation and risk management actions. Further information is set out in the Risk Management section of this Annual Report.

In addition, the Audit and Compliance Committee reviewed financial risk, tax risks, treasury policy and risks, and Group insurance coverage.

Internal Audit

The Internal Audit team provides independent and objective assurance, and consulting services over the design and effectiveness of Millicom’s internal control environment, governance, and risk management processes. The Internal Audit team employs a robust methodology that supports the systematic execution of internal audit activities reflected through a risk-based annual Internal Audit Plan.

The annual Internal Audit Plan is developed in alignment with the strategic risks of Millicom as well as consideration of the company’s strategic priorities, input from senior management, external audit findings, industry-relevant developments, and Internal Audit’s knowledge of the business. Before the start of the fiscal year, the Audit and Compliance Committee approves the annual Internal Audit plan, which includes assurance and advisory projects and other risk assessment initiatives, and assesses the adequacy of the budget and resources.

Execution of the 2024 Internal Audit Plan provided the Group Leadership Team and the Audit and Compliance Committee with an independent view of the effectiveness of Millicom’s internal control environment and governance processes in operational, financial, compliance, and technology areas. At each meeting, the Audit and Compliance Committee received a report on internal audit activities, progress against the plan, updates to the plan, and results of the audits completed in the period, including associated recommendations and management action plans where findings were identified.

Internal Controls and SOX

The Audit and Compliance Committee received the results of management's testing of key controls and testing by the external auditors. Management concluded that the Group had maintained effective internal controls over financial reporting.

A debrief of the Sarbanes-Oxley status program was held. The Audit and Compliance Committee also reviewed and approved the planned scope of the 2024 program and approach to testing of key controls.

The Committee reviewed regular reports on the results of management testing of key controls and the progress made to address any control gaps.

II. Compensation and Talent Committee

Letter from the Chair of the Compensation and Talent Committee

The key remuneration highlights for the year are summarized below. Further details are provided in the "Compensation information" section.

The Committee meets regularly to review executive compensation and other talent-related matters to ensure competitiveness across our markets. To achieve our goals and foster a results-oriented company, our compensation model is based on a performance framework, that encompasses both short-term and long-term incentives. Talent remains a fundamental cornerstone for our success. As such, we recognize the importance of continuing to integrate talent management strategies with our compensation framework.

The Compensation and Talent Committee is composed of three Board of Directors members: Mr. Bruce Churchill (Chair), Ms. Maria Teresa Arnal, and Mr. Pierre-Emmanuel Durand.

Leadership changes

116

Marcelo Benitez assumed the role of CEO of Millicom on June 1, 2024. With an extensive 27-year professional journey in the Millicom Group, he brings a wealth of experience in the telecommunications and technology sectors, along with a profound understanding of the Latin American region.

In April 2024, as part of a planned succession process, Bart Vanhaeren was appointed Chief Financial Officer. Bart brings 14 years of experience at Millicom, having held various senior financial and management leadership roles throughout his tenure. Most recently, as VP of Corporate Finance, he oversaw the Corporate Finance division, which includes the Company’s Treasury, Tax, Mergers & Acquisitions, and Corporate Administration activities.

Efficiency Initiatives

In 2024, we continued to implement an efficiency plan which was focused on improving operations and driving sustainable growth. This plan aimed to optimize key areas of our business, streamline processes, and ensure effective resource allocation. This plan was designed to strengthen our competitive edge, improve operational efficiency, and support our long-term goals in line with the business and the macroeconomic context of the region.

Remuneration Policy

Our 2024 remuneration policy focuses on a total compensation approach, which consists of a base salary and benefits. The policy also includes a significant variable component paid in cash and deferred cash or shares. These variable elements of remuneration are tied to performance measures.

For the entire Millicom Group, the annual bonus is determined using a combination of financial metrics and personal performance.

The 2024 Long-Term Incentive plan was offered to Millicom’s top management team and includes a combination of share appreciation and company performance measures. We encourage our top leaders to take a longer-term view on positive business performance in alignment with Company and shareholder interests.

In 2024, a Performance Deferred Cash Plan was introduced for the General Managers of each Tigo operation, offering deferred cash payments linked to financial metrics. This plan was designed to ensure a sustained focus on performance in each country.

During the 2024 AGM, we received ample support for our remuneration approach: 80.35% Approval for Remuneration Policy, 80.50% Approval for share-based incentive plans and 94.26% Approval for Remuneration Report.

As part of our ongoing commitment to strong governance, we continue to adhere to the comprehensive "claw-back" policy adopted by the Board. This policy was implemented in response to specific rules issued by the SEC under Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (Dodd-Frank). This policy ensures that if our financial statements are restated due to errors, misstatements, or misconduct, we have mechanisms in place to recoup excess compensation paid to current and former executive officers. By aligning with regulatory requirements and industry best practices, we reinforce responsible governance and shareholder value.

There were no deviations to the remuneration policy and the Board is confident that the policy has operated as intended over the year. A summary of the elements of executive pay for 2024 is set out on the following pages.

On behalf of the Board, I hope you find the 2024 Compensation Information section insightful.

2. Our Compensation Philosophy and Core Principles

The philosophy, guidelines, objectives, and policy applicable to remuneration of the Global Senior Management Team were approved by the shareholders (item 23) of the AGM held on May 23, 2024.

2.1 Core Principles

The Compensation and Talent Committee worked using the following objectives for the Global Senior Management Team's compensation.

119


What we strive for			What it means
Competitive and fair			Levels of pay and benefits to attract and retain the right people.
Drive the right behaviors			Reward policy and practices that drive behaviors supporting our Company strategy and business objectives.
Shareholder alignment			Variable compensation plans that support a culture of entrepreneurship and performance and incorporate both short-term and longer-term financial and operational metrics strongly correlated to the creation of shareholder wealth. Long-term incentives are designed to maintain sustained commitment and ensure that the interests of our Global Senior Management Team are aligned with those of our shareholders.
Pay for performance			Total reward structured around pay in line with performance, providing the opportunity to reward strong corporate and individual performance. A significant proportion of top management's compensation is variable (at risk) and based on measures of personal, company and share price performance directly attributable to short-term and long-term value creation.
Transparency			Millicom is committed to expanding transparency, including disclosure around pay for performance, links to value creation, etc.
Market competitive and representative remuneration			Compensation is designed to be market competitive and representative of the seniority and importance of roles, responsibilities and geographical locations of individuals.
Retention of key talent			Variable compensation plans include a significant portion of deferred share-based or cash compensation, the payout of which is conditional on future employment with the Company for three-year rolling periods, starting on the grant date.
Executive management to be "invested"			The Global Senior Management Team, through Millicom’s share ownership guidelines, is required to reach and maintain a significant level of personal ownership of Millicom shares.

To drive the right behaviors and ensure expectations are aligned, we communicate clearly to our employees what we do and do not do when it comes to compensation. A summary is set out in the table below:


What we do			What we don't do
Align pay and performance.			Create special executive perquisites.
Designate a substantial majority of executive pay as at risk, based on a mix of absolute and relative financial and share price performance metrics.			Permit executives to hedge company shares.
Impose limits on maximum incentive payouts.			Provide dividends or dividend equivalents on unearned PSUs.
Engage in a rigorous target-setting process for incentive metrics.			Offer tax gross-ups related to change in control.
Set our STI threshold to pay only at 95% and higher levels of achievement.
Maintain robust share ownership guidelines for our top 30 executives.
Provide “double-trigger” change in control provisions in equity awards.
Maintain clawback policies that apply to our performance-based incentive plans.
Retain an independent compensation consultant

2.2 Elements of Executive Pay

Compensation for the Global Senior Management Team in 2024 comprised a base salary, a short-term incentive (”STI”) plan and a long-term incentive (“LTI”) plan, together with pension contributions and other benefits (e.g. healthcare).

Salary


Pay element	Purpose	Maximum opportunity
Purpose and link to strategy	Designed to be market competitive to attract and retain talent	No absolute maximum has been set for Group Leadership Team salaries. The committee considers increases on a case-by-case basis based on peer comparison. Pay increases usually reflect a combination of roles and responsibilities, local market conditions and individual performance.
Operational execution	Paid monthly in cash in U.S. dollars or the home currency of the executive	The Compensation and Talent Committee aims to set salaries for the Group Leadership Team at the median of the peer group.
	Reviewed by the Compensation and Talent Committee every March

120


STI
Pay element	Purpose	Payout opportunity
Purpose and link to strategy	The STI links reward to key business targets (75%) and individual contribution / personal performance (25%). Financial and operational targets are: Service Revenue (25%); EBITDA (25%) and EFCF. The STI aligns with shareholders’ interests through the provision of a portion of the payment delivered in share units deferred over three years (DSP) for the senior leadership team. The DSP is awarded upon achieving the performance targets, with 30% paid after one year, 30% after the second year and 40% after the third year of the grant date. These plans help incentivize and motivate leadership to execute strategic plans in operational decision-making and achieve short-term performance goals, impacting Company performance and enhancing its value.	Service Revenue: With less than 98% of the target the award falls to 0%. The threshold achievement is 98% of the target, resulting in a payout of 90%. The opportunity is 200% for the achievement of 104%. EBITDA: With less than 90% of the target the award falls to 0%. The threshold achievement is 90% of the target, resulting in a payout of 10%. The opportunity is 200% for the achievement of 110%. EFCF: With less than 92.5% of the target the award falls to 0%. The threshold achievement is 92.5% of the target, resulting in a payout of 50%. The opportunity is 300% for the achievement of 120%.
Benchmarking	Our STI is a key component of the Millicom Group culture. We benchmark to peer companies within the U.S. and Latin America	Each year the Compensation and Talent Committee determines the annual STI opportunity for the Group Leadership Team.


LTI
Pay element	Purpose	Payout opportunity
Purpose and link to strategy	The LTI links an important part of overall Global Senior Management Team compensation with the interests of our shareholders, encouraging long-term value creation and retention. Millicom maintains unified goals and objectives in the LTI program for the Global Senior Management Team, with the purpose of driving the successful achievement of three-year performance goals designed to enhance long-term value of the Company. The LTI is a share-based plan whereby share awards that are granted fully vest at the end of a three-year period, subject to achievement of certain performance measures and fulfillment of conditions. The weights for the LTI component are: Stock Appreciation Rights (SARs) (60%); Restricted Stock Units (RSUs) (30%); and Performance Shares with ESG target achievement (10%). The peer group for the LTI 2024 is: America Movil, TIM Brazil, TEF Brazil, Entel Chile, Lilac, Telecom Argentina, Grupo Televisa, Megacable.	Stock Appreciation Rights (SARs): Payout is based on the share price appreciation at the time of exercise, resulting in the delivery of shares. Restricted Stock Units (RSUs): Payout is subject to the share price at the time of vesting. Performance Shares based on ESG metric: If achievement is less than 80% of the target, the award is 0%. Between 80% and 100% of the target, the award is adjusted pro-rata based on performance, starting from 0% to 100% payout. The payout is capped at 100% achievement.
Benchmarking	Our LTI is a key component of the Millicom Group culture.	Each year the Compensation and Talent Committee determines the annual LTI opportunity for the Group Leadership Team.
	For executives we benchmark to peer companies based on executive location.

2.3 Other Employment Terms and Conditions

Notice of termination: If the employment of a member of Millicom’s Group Leadership Team is terminated, a notice period of up to 12 months potentially applies. The Board regularly reviews best practices in executive compensation and governance and revises policies and practices when appropriate. Millicom's change-in-control agreements for eligible executives include "double-trigger" provisions, which require an involuntary termination (in addition to change in control) for accelerated vesting of awards.

Deviations from the policy and guidelines: In special circumstances, the Board may deviate from the above policy and guidelines; for example, providing additional variable remuneration in the case of exceptional performance.

2.4 Other Executive Compensation Policies

121

On December 1, 2023, Millicom adopted a compensation recoupment policy, which is included as Exhibit 97.1 to this Annual Report. The policy remains in effect in 2024 and provides for the recoupment of certain executive compensation in the event of an accounting restatement resulting from material noncompliance with financial reporting requirements.

In addition, the Company’s insider trading policy prohibits any hedging or speculative transactions in the Company’s shares, including the use of options and other derivatives. It also prohibits directors and employees from selling the Company’s stock short.

3. Total Group Leadership Team compensation

The compensation for the Group Leadership Team members is heavily weighted to variable compensation subject to a vesting period. As a result, total reported compensation may differ significantly relative to the actual realized compensation in any given year. Aggregate compensation paid to our Group Leadership Team in 2024 was $25 million. In addition, for the year ended December 31, 2024, our Group Leadership Team received 136,464 grant units of shares for a total amount of $2 million and 90,809 grant units related to stock appreciation rights in connection with the short-term and long-term share based incentive programs, and the Company set aside $1 million for pension obligations. For more information, see Note B.4 to our audited consolidated financial statements, included elsewhere in this Annual Report.

Change in Registrant's Certifying Accountant

On May 23, 2024, at the Annual General Meeting of Shareholders, KPMG Audit S.à r.l. and KPMG LLP (together, “KPMG”) were elected as our independent registered public accounting firm for the 2024 fiscal year. Such election and change of independent registered public accounting firm was adopted at the proposal of the Nomination Committee and in accordance with the recommendation from the Audit and Compliance Committee. Accordingly, Ernst & Young S.A. (“EY”) was not re-elected for another term and was dismissed as our independent registered public accounting firm.

The audit report of EY on our consolidated financial statements as of December 31, 2023 and 2022, and for the three-year period ended December 31, 2023, did not contain any adverse opinion or disclaimer of opinion and was not qualified or modified as to uncertainty, audit scope or accounting principles. During the fiscal year ended December 31, 2023, and through the date of filing of this Annual Report, there has not been any disagreement on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreement, if not resolved to the satisfaction of EY, would have caused them to make reference to the subject matter of the disagreement in connection with their report, nor has there been any “reportable event” as described in Item 16F(a)(1)(v) of Form 20-F.

We have provided a copy of the above statements to EY and requested that EY furnish us with a letter addressed to the SEC stating whether or not they agree with the above disclosure. A copy of that letter, dated April 8, 2025, is filed as Exhibit 15.3 to this Annual Report.

Further, during the fiscal year ended December 31, 2023, and through the date of filing of this Annual Report, we have not consulted with KPMG regarding: (i) the application of accounting principles to a specified transaction, either completed or proposed; (ii) the type of audit opinion that might be rendered with respect to the Group’s consolidated financial statements; or (iii) any matter that was either the subject of a disagreement as that term is defined in Item 16F(a)(1)(iv) of Form 20-F or a “reportable event” as described in Item 16F(a)(1)(v) of Form 20-F.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of

Millicom International Cellular S.A.:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated statement of financial position of Millicom International Cellular S.A. and subsidiaries (the Company) as of December 31, 2024, the related consolidated statements of income, comprehensive income, changes in equity, and cash flows for the year ended December 31, 2024, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2024, and its financial performance and its cash flows for the year ended December 31, 2024, in conformity with International Financial Reporting Standards Accounting Standards as issued by the International Accounting Standards Board.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission , and our report dated April 8, 2025 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audit included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audit provides a reasonable basis for our opinion.

F-2

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Sufficiency of audit evidence over certain service revenue streams

As discussed in Note B.1.1 to the consolidated financial statements, the Company recorded $5,804 million of revenue of which $5,417 million related to service revenue streams for the year ended December 31, 2024. The processing and recording of revenue from these revenue streams is reliant upon multiple information technology (IT) systems.

We identified the evaluation of the sufficiency of audit evidence over revenue from certain service revenue streams as a critical audit matter. Subjective auditor judgment was required in evaluating the sufficiency of audit evidence over these service revenue streams due to the volume of data and number of IT systems utilized throughout these revenue recognition processes. Specifically, obtaining an understanding of the systems and processes to evaluate whether relevant revenue data was processed and recorded across the various IT systems required significant auditor effort and specialized skills and knowledge.

The following are the primary procedures we performed to address this critical audit matter. We applied auditor judgment to determine the nature and extent of procedures to be performed over these service revenue streams, including the IT systems tested. We evaluated the design and tested the operating effectiveness of certain internal controls related to these service revenue processes. We reconciled information from the IT systems to the general ledger. For a selection of transactions, we compared the amount of revenue recorded to underlying documentation, including Company internal data, executed contracts, and other third-party data. In addition, we involved IT professionals with specialized skills and knowledge who assisted in testing relevant IT systems and internal controls over the Company’s revenue recognition processes. We evaluated the sufficiency of audit evidence obtained by assessing the results of procedures performed, including the relevance and reliability of evidence obtained.

Goodwill impairment analysis for the Nicaragua cash-generating unit

As discussed in Notes E.1.5 and E.1.6 to the consolidated financial statements, the carrying amount of goodwill as of December 31, 2024 was $4,094 million, of which $197 million was allocated to the Nicaragua cash-generating unit (CGU). The Company tests for impairment of goodwill from CGUs at least annually and more frequently if events or changes in circumstances indicate that the carrying value may be impaired. The carrying value is compared to the recoverable amount of each CGU measured based on value-in-use using a discounted cash flow model. Based on the Company’s analysis, the Company determined that the recoverable amount of the Nicaragua CGU was in excess of its carrying value and therefore did not record any goodwill impairment.

We identified the evaluation of the goodwill impairment analysis for the Nicaragua CGU as a critical audit matter. Subjective auditor judgment and specialized skills and knowledge were required to evaluate certain assumptions used in measuring the recoverable amount of the CGU. We performed sensitivity analyses as a risk assessment procedure over assumptions used to estimate the recoverable amount of this CGU. The estimated recoverable amount of the CGU was sensitive to minor changes in the weighted average cost of capital (WACC) after tax rate, perpetual growth rate, average capital expenditure (CAPEX) intensity and average earnings before interest, taxes depreciation and amortization (EBITDA) margin assumptions and such assumptions were subject to measurement uncertainty.

F-3

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls related to the Company’s goodwill impairment process for the Nicaragua CGU, including controls over the development and selection of the WACC after tax rate, perpetual growth rate, average CAPEX intensity and average EBITDA margin. We evaluated the average CAPEX intensity and average EBITDA margin assumptions by considering current and past performance.

In addition, we involved valuation professionals with specialized skills and knowledge, who assisted in:

•comparing the Company’s WACC after tax rate to a range of independently developed WACC after tax rates using publicly available market data

•evaluating the perpetual growth rate used by the Company by comparing it to industry and market data for comparable entities

•recalculating the recoverable amount of the Nicaragua CGU

Notes to the Consolidated Financial Statements For the years ended December 31, 2024, 2023 and 2022

Introduction

Corporate Information

Millicom International Cellular S.A. (the “Company” or “MIC S.A.”), a Luxembourg Société Anonyme, and its subsidiaries, joint ventures, joint operations and associates (the “Group” or “Millicom”) is a provider of cable and mobile services dedicated to emerging markets in Latin America. Millicom provides high speed broadband and innovation around The Digital Lifestyle® services through its principal brand Tigo.

The Company’s shares are traded since January 9, 2019, on the Nasdaq Stock Market in the U.S. under the ticker symbol TIGO. As of December 31, 2024 the Company's shares were also traded as Swedish Depositary Receipts on the Stockholm stock exchange under the symbol TIGO SDB (formerly MIC SDB). The Company has its registered office at 148-150 Boulevard de la Pétrusse , L-2330 Luxembourg, Grand Duchy of Luxembourg and is registered with the Luxembourg Register of Commerce under the number RCS B 40 630.As of December 31, 2024 Atlas S.A.S. (formerly known as Atlas Luxco S.à r.l) holds 40.37% of Millicom shares. whose final beneficial owner is Xavier Niel and his family.

On April 4, 2025, the Board of Directors authorized these consolidated financial statements for issuance.

Business activities

Millicom operates its mobile businesses in Latin America (Bolivia, Colombia, El Salvador, Guatemala, Honduras, Nicaragua, Panama and Paraguay). Millicom operates various cable and fixed line businesses in Latin America (Bolivia, Colombia, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, Panama and Paraguay). Millicom also provides direct to home satellite service in most of its markets. Millicom also provides Mobile Financial Services (MFS) and tower infrastructure and services.

Our reportable segments consist of Guatemala, Colombia, Panama, Bolivia, Honduras, Paraguay and Other, which includes Nicaragua, Costa Rica and El Salvador.. The Honduras joint venture performance is reviewed by the CODM in a similar manner as for the Group’s fully owned operations and is therefore also shown as a separate operating segment at 100%. However, these amounts are subsequently eliminated in order to reconcile with the Group consolidated numbers, as shown in the reconciliations included in note B.3. Segmental information.

Current macroeconomic environment

The macroeconomic environment remained stable during 2024, although the Colombian peso average foreign exchange rate appreciated 5.6% and the Paraguayan guarani average foreign exchange rate depreciated 3.6%, respectively. In Bolivia, commissions on purchases of U.S dollars at the official rate continued to increase, reaching much as $27 million during 2024, reflecting the acute shortage of U.S dollars available at the official rate.

The Group continues to monitor the developments of the aforementioned events and their potential impact on performance and accounting considerations.

Climate-related risks

As already publicly announced and discussed elsewhere in our external reporting, our goal is to raise the bar on the Group’s contribution on environmental, societal and governance matters. In particular, the Group has committed to short-term goals validated by the Science Based Targets initiative (SBTi). The Group is also committed to the long-term goal of net zero emissions by or before 2050. Although there is no single explicit standard on climate-related matters under IFRS, climate risk and other climate-related matters may impact a number of areas of accounting. Up to now, the Group has not been significantly impacted by climate change, and, currently, management has not considered the climate-related risks as part of the Group's top twelve key risks. Nevertheless, management will continue monitoring every year the potential risks resulting from the effects of climate change in the form of natural disasters, such as extreme weather events affecting our 'Networks and infrastructure resilience'. So far, management has not identified nor considered any material impacts of climate change on assumptions used (e.g. for impairment tests, fair value measurement, etc.) and on the Group's financial reporting (e.g. provisions, fixed assets, etc.).

IFRS Consolidated Financial Statements

Basis of preparation

These financial statements have been prepared in accordance with IFRS Accounting Standards as issued by the International Accounting Standard Board ("IASB") and in accordance with IFRS Accounting Standards as adopted by the European Union. These financial statements have been prepared on a historical cost basis, except for certain items including derivative financial instruments (measured at fair value) and financial instruments that contain obligations to purchase own equity instruments (measured at the present value of the redemption price).

Notes to the Consolidated Financial Statements For the years ended December 31, 2024, 2023 and 2022

This section contains the Group’s material accounting policies that relate to the financial statements as a whole. Material accounting policies specific to one note are included within that note.

Consolidation

The consolidated financial statements of the Group comprise the financial statements of the Company and its subsidiaries as of December 31 of each year. The financial statements of the subsidiaries are prepared for the same reporting year as the Company, using consistent accounting policies. All intra-group balances, transactions, income and expenses, and profits and losses resulting from intra-group transactions are eliminated.

Foreign currency

Financial information in these financial statements are shown in the US dollar presentation currency of the Group and rounded to the nearest million (US$ million) except where otherwise indicated. The financial statements of each of the Group’s entities are measured using the currency of the primary economic environment in which each entity operates (the functional currency). The functional currency of each subsidiary, joint venture and associate reflects the economic substance of the underlying events and circumstances of these entities. Except for El Salvador where the functional currency is US dollar, the functional currency in other countries is the local currency.

The results and financial position of all Group entities (none of which operate in an economy with a hyperinflationary environment) with functional currency other than the US dollar presentation currency are translated into the presentation currency as follows:

(i) Assets and liabilities are translated at the closing rate on the date of the statement of financial position;

(ii) Income and expenses are translated at average exchange rates (unless this average is not a reasonable approximation of the cumulative effect of the rates prevailing on the transaction dates, in which case income and expenses are translated at the dates of the transactions); and

(iii) All resulting exchange differences are recognized as a separate component of equity (currency translation reserve), in the caption “Other reserves”.

On consolidation, exchange differences arising from the translation of net investments in foreign operations, and of borrowings and other currency instruments designated as hedges of such investments, are recorded in equity. When the Group disposes of or loses control or significant influence over a foreign operation, exchange differences that were recorded in equity are recognized in the consolidated statement of income as part of gain or loss on sale or loss of control and/or significant influence.

Goodwill and fair value adjustments arising on acquisition of a foreign operation are treated as assets and liabilities of the foreign operation and translated at the closing rate.

The following table presents functional currency translation rates for the Group’s locations to the US dollar on December 31, 2024 and 2023 and the average rates for the years ended December 31, 2024, 2023 and 2022.

Notes to the Consolidated Financial Statements For the years ended December 31, 2024, 2023 and 2022

New and amended IFRS accounting standards

The following changes to standards have been adopted by the Group and did not have any significant impact on the Group’s accounting policies or disclosures and did not require retrospective adjustments:

◦Amendments to IFRS 16 'Leases: Lease Liability in a Sale and Leaseback': The amendment specifies the requirements that a seller-lessee uses in measuring the lease liability arising in a sale and leaseback transaction when the terms include variable lease payments, to ensure the seller-lessee does not recognize any amount of the gain or loss that relates to the right of use it retains.

◦Amendments to IAS 1, 'Presentation of Financial Statements': These amendments aim to improve the information an entity provides when its right to defer settlement of a liability is subject to compliance with covenants within twelve months after the reporting period.

◦Amendments to IAS 7, 'Statement of Cash Flows' and IFRS 7, 'Financial Instruments: Disclosures: Supplier Finance Arrangements': These amendments require disclosures to enhance the transparency of supplier finance arrangements and their effects on a company’s liabilities, cash flows and exposure to liquidity risk. The disclosure requirements are the IASB’s response to investors’ concerns that some companies’ supplier finance arrangements are not sufficiently visible, hindering investors’ analysis.

Management is currently assessing the potential impact on the Group consolidated financial statements of the IFRS Interpretations Commitee's agenda decision regarding clarifications on certain disclosures for segment reporting.

The following Amendments to standards are effective for annual periods starting on January 1, 2025 (Amendments to IAS 21, 'The Effects of Changes in Foreign Exchange Rates': Lack of Exchangeability). These Amendments, effective for annual periods starting on January 1, 2025, aim to determine whether a currency is exchangeable into another currency, and the spot exchange rate to use when it is not . The Group has assessed the Amendments to IAS 21 impacts in its consolidated financial statements concluding that the Bolivia operation is under its scope. As of December 31, 2024, the Group has not finalized the full assessment of the financial impact of the Amendments to IAS 21. However, management anticipates that its adoption could result in an adjustment to retained earnings as of January 1, 2025. Further details will be disclosed in the 2025 financial statements.

The following standards and amendments are effective for annual periods starting on January 1, 2026 (Amendments to IFRS 9, IFRS 7 and Annual Improvements) or January 1, 2027 (IFRS 18) and their potential impact on the Group consolidated financial statements is currently being assessed by management:

▪Amendments to IFRS 9 and IFRS 7 (not yet endorsed by the EU): Amendments to IFRS 9 are clarifications to the classification and measurement of financial instruments (such as clarifications on derecognition of financial liabilities, among others). Amendments to IFRS 7 include additional disclosures requirements (such as those for financial instruments with contingent features, among others).

▪Amendments to IFRS 9 and IFRS 7, issued on 18 December, 2024 (not yet endorsed by the EU): These Amendments to IFRS 9 and IFRS 7 aim to help companies to improve their reporting of the financial effects of nature-dependent electricity contracts, commonly structured as power purchase agreements (PPAs) and apply only to contracts referencing nature-dependent electricity in which a company is exposed to variability in the underlying amount of electricity because the source of electricity generation depends on uncontrollable natural conditions (e.g. wind or solar energy). The changes to IFRS 9 clarify the application of the ‘own-use’ exemption and permit hedge accounting if these contracts are used as hedging instruments while the changes to IFRS 7 add new disclosure requirements on the company’s financial performance and cash flows.

▪Annual Improvements to IFRS Standards, affecting IFRS 1, IFRS 7, IFRS 9, IFRS 10 and IAS 7 (not yet endorsed by the EU).

▪IFRS 18, 'Presentation and Disclosure in Financial Statements' (not yet endorsed by the EU): IFRS 18 will replace IAS 1. Its aim is to improve the usefulness of information presented and disclosed in financial statements, giving investors more transparent and comparable information about companies' financial performance.

Judgments and critical estimates

The preparation of IFRS financial statements requires management to use judgment in applying accounting policies. It also requires the use of certain critical accounting estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. These estimates are based on management's best knowledge of current events, actions and best estimates as of a specified date, and actual results may ultimately differ from these estimates. Areas involving a higher degree of judgment or complexity, or areas where assumptions and estimates are significant to the financial statements are disclosed in each note and are summarized below:

F-15


Notes to the Consolidated Financial Statements For the years ended December 31, 2024, 2023 and 2022

Judgments

Management applies judgment in accounting treatment and accounting policies in preparation of these financial statements. In particular, a significant level of judgment is applied regarding the following items:

• Acquisitions – measurement at fair value of existing and newly identified assets, including the measurement of property, plant and equipment and intangible assets (e.g. particularly the customer lists being sensitive to significant assumptions as disclosed in note A.1.2.), liabilities, contingent liabilities and remaining goodwill; the assessment of useful lives (see notes A.1.2., E.1.1., E.1.5., E.2.1.);

• Impairment testing – key assumptions related to future business performance, perpetual growth rates and discount rates (see notes E.1.2., E.1.6., E.2.2.);

• Revenue recognition – whether or not the Group acts as principal or as an agent, when there is one or several performance obligations and the determination of stand-alone selling prices (see note B.1.1.);

• Contingent liabilities – whether or not a provision should be recorded for any potential liabilities (see note G.3.);

• Leases – In determining the lease term, including the assessment of whether the exercise of extension or termination options is reasonably certain and the corresponding impact on the selected lease term (see note E.3.);

• Control – whether Millicom, through voting rights and potential voting rights attached to shares held, or by way of shareholders’ agreements or other factors, has the ability to direct the relevant activities of the subsidiaries it consolidates, or jointly direct the relevant activities of its joint ventures (see notes A.1., A.2.);

• Discontinued operations and assets held for sale – definition, classification and presentation (see notes A.4., E.4.1.) as well as measurement of potential provisions related to indemnities;

• Deferred tax assets – recognition based on likely timing and level of future taxable profits together with future tax planning strategies (see notes B.6.3.and G.3.2.);

Estimates

Estimates are based on historical experience and other factors, including reasonable expectations of future events, such as current macro-economic challenges. These factors are reviewed in preparation of the financial statements although, due to inherent uncertainties in the evaluation process, actual results may differ from original estimates. Estimates are subject to change as new information becomes available and may significantly affect future operating results. Significant estimates have been applied in respect of the following items:

• Accounting for property, plant and equipment, and intangible assets in determining fair values at acquisition dates, particularly for assets acquired in business combinations and sale and leaseback transactions (see notes A.1.and E.2.1.);

• Useful lives of property, plant and equipment and intangible assets (see notes E.1.1., E.2.1.);

• Provisions, in particular provisions for asset retirement obligations, restructuring, legal and tax risks (see notes F.4. and B.4.);

• Tax liabilities, in particular in respect of uncertainty over income tax treatments (see note F.4.);

• Revenue recognition (see note B.1.1.);

• Impairment testing including weighted average cost of capital ("WACC"), EBITDA margins, Capex intensity and long term growth rates (see note E.1.6.);

• For leases, estimates in determining the incremental borrowing rate for discounting the lease payments in case interest rate implicit in the lease cannot be determined (see note E.3. );

• Estimates for defined benefit obligations (see note B.4.2.);

• Accounting for share-based compensation in particular estimates of forfeitures and future performance criteria (see notes B.4.1., B.4.3.).

Effective in 2024, we revised the estimated useful lives of our fiber optic network assets and related equipment/software. this is considered a change in accounting estimate under IAS 8.

◦Fiber Optic Network: Useful life increased from 15 years to 25 years

◦Related equipment/Software: Useful life range increased to 5-10 years (previously 5-7 years for equipment and 5 years for software)

This change is applied prospectively, meaning there is no impact on financial statements for prior periods. Fully depreciated assets remain fully depreciated; their cost will not be reset.

For the full year 2024, this change is expected to decrease depreciation expense by approximately $48 million compared to what the depreciation charge would have been using previous estimated useful lives. Estimating the impact on future years is impractical.

F-16


Notes to the Consolidated Financial Statements For the years ended December 31, 2024, 2023 and 2022

While the change also affects lease right-of-use assets and asset retirement obligation provisions, the impact on these areas is considered immaterial.

During 2023, the estimated useful lives of some property, plant and equipment were revised. As a result, the estimated useful lives of the Group's towers, poles and ducts were changed from 15 to 25 years, while the related civil works' useful lives were increased from 10 to 15 years. These changes were considered a change in accounting estimate per IAS 8 "Accounting Policies, Changes in Accounting Estimates and Errors" and therefore accounted for prospectively, meaning that no changes should be accounted for past periods. This also applies to assets that are fully depreciated and for which no new cost should be reset. (i.e., they remain fully depreciated).

For the full year 2023, the net effect of the changes represent a decrease in depreciation expense of approximately $27 million compared to what we expected the depreciation charge to be using previous estimated useful lives, while estimating the net effect of the changes in depreciation for future years is impractical. This change in accounting estimate also affects the lease right-of-use assets (for those being depreciated over the shorter of useful life and lease term) and on asset retirement obligation provisions. However, the impact of the change is immaterial.

International Tax reform-Pillar II Model

The Millicom Group is within the scope of the OECD Pillar Two Model rules (also referred to as the “Global Anti-Base Erosion” or “Globe” Rules). Pillar Two legislation came into effect on January 1, 2024.

The Group has run testing under the OECD Transitional Safe Harbour rules, which are transitional rules mainly based on the Country by Country Report of the Group. As of December 31, 2024, it results that all jurisdictions within Millicom Group meet at least one of the transitional safe harbour rules except for Paraguay. The full Globe calculation carried out for Paraguay did not result in a material top-up tax for the Group. See note B.6.3. for the estimated amount of unrecognized tax losses.

A. The Millicom Group

The Group comprises a number of holding companies, operating subsidiaries and joint ventures with various combinations of mobile, fixed-line telephony, cable and wireless Pay TV, Broadband Internet and Mobile Financial Services (MFS) businesses.

A.1. Subsidiaries

Subsidiaries are all entities which Millicom controls. Millicom controls an entity when it is exposed to, or has rights to variable returns from its investment in the entity, and has the ability to affect those returns through its power over the subsidiary. Millicom has power over an entity when it has existing rights that give it the current ability to direct the relevant activities, i.e. the activities that significantly affect the entity’s returns. Generally, control accompanies a shareholding of more than half of the voting rights although certain other factors (including contractual arrangements with other shareholders, voting and potential voting rights) are considered when assessing whether Millicom controls an entity. For example, although Millicom holds less than 50 % of the shares in its Colombian businesses, it holds more than 50 % of shares with voting rights. The contrary may also be true (e.g. Honduras where we own 66.7% of the shares but there is a super majority requirement at the board for decisions about the relevant activities of the operation). The Group's main subsidiaries are as follows:

A.1.1. Accounting for subsidiaries and non-controlling interests

Subsidiaries are fully consolidated from the date on which control is transferred to Millicom. If facts and circumstances indicate that there are changes to one or more of the elements of control, a reassessment is performed to determine if control still exists. Subsidiaries are de-consolidated from the date that control ceases. Transactions with non-controlling interests are accounted for as transactions with equity owners of the Group. Gains or losses on disposals of non-controlling interests are recorded in equity. For purchases from non-controlling interests, the difference between any consideration paid and the relevant share acquired of the carrying value of net assets of the subsidiary is also recorded in equity.

A.1.2. Acquisition of subsidiaries and changes in non-controlling interests in subsidiaries

Scope changes 2024

There were no material acquisitions or disposals during the year ended December 31, 2024.

On July 31, 2024, Millicom announced that it has signed a non-binding memorandum of understanding with Telefonica for the potential acquisition of Telefonica’s stake in Telefonica Colombia (Coltel), as part of a broader intended combination of Coltel and TigoUne, Millicom's 50%-owned operation in Colombia. Millicom intends to offer to purchase La Nación’s and other minority interests in Coltel for cash at the same purchase price per share offered to Telefonica, as well as Empresas Públicas de Medellin’s (EPM) 50% interest in TigoUne for cash at a valuation multiple comparable to the one implied by the Coltel acquisition. The total investment by Millicom would be approximately $1 billion, and the transaction would be subject to negotiation of definitive agreements and receipt of regulatory approvals. See note H. for details/updates related to this transaction.

Scope changes 2023

There were no material acquisitions in 2023.

Scope changes 2022

As of June 14, 2022, the Group received the formal notification from the minority shareholders of Telecomunicaciones Digitales, S.A (formerly Cable Onda S.A.) confirming the exercise of their put option right to sell their remaining 20% shareholding to Millicom for an amount of approximately $290 million. The transaction was closed on June 29, 2022 and the payment was applied against the already recorded put option liability of $290 million. As a result, the non-controlling interests' carrying value of $78 million have been transferred to the Group's equity.

A.1.3. Disposal of subsidiaries and formation of a joint operation

Colombia

On February 26, 2024, Tigo Colombia and Telecomunicaciones S.A. ESP BIC signed a a binding framework agreement for the implementation of a single mobile access network as well as for sharing the radioelectric spectrum usage permits, whose only users would be the two shareholders participating in the such agreement. See notes A.2. and E.4.2. for details.

Costa Rica

On August 1, 2024, we signed a binding agreement with Liberty Latin America to combine our operations in Costa Rica in a cashless merger in which Millicom would retain a minority equity ownership of approximately 14%. The transaction is subject to closing conditions, including regulatory approvals and is expected to close in H2 2025. Hence, as of December 31, 2024 the transaction is still not meeting the IFRS 5: "Non-current Assets Held for Sale and Discontinued Operations" criteria

Tanzania

On April 5, 2022, Millicom completed the sale for an initial cash consideration of approximately $101 million (subject to final price adjustment). The net assets de-consolidated on the date of the disposal amounted to $79 million and the net gain on disposal was calculated at $109 million. In accordance with IFRS 5, our former operations in Tanzania are shown in a single line item on the face of the consolidated statement of income under 'Profit (loss) from discontinued operations, net of tax.

The sale agreement for our former operations in Tanzania contained indemnification obligations covering potential tax and legal contingencies, to be offset against tax and litigation baskets. The sale agreement also provided for a purchase price adjustment based on working capital at the time of closing. The parties disagreed regarding this adjustment and previously referred to the matter to an independent expert. In addition, the agreement also provided an IPO1 adjustment clause valid until April 5, 2024, whereby Millicom would reimburse the buyer for any negative difference between the share price per share on the IPO date and the one implied by this sale; the IPO did not happen and no claim was made. In December 2024, Millicom booked a provision and paid to Honora $3 million for final settlement. This final settlement releases both parties of all claims arising under the sale agreement .

(a) The net assets de-consolidated on the date of the disposal, as well as the gain on disposal, were as follows:

Sale of Lati International S.A and other assets to SBA

On October 28, we agreed to sell Lati International, S.A. and other assets encompassing a portfolio of more than 7,000 towers in Central America to SBA Telecommunications LLC. Closing is subject to regulatory approvals and other closing conditions and is expected to occur in mid-2025. We have also entered into other agreements including a 15-year leaseback for the sites, and a new build-to-suit agreement under which SBA will build up to 2,500 additional sites for Millicom in the same markets. As of December 31, 2024, except for the Tower sales in Nicaragua (see note B.4.2. and H.), the transaction is still not meeting the IFRS 5: "Non-current Assets Held for Sale and Discontinued Operations" criteria.

Other disposals

For the years ended December 31, 2024, 2023 and 2022, Millicom did not dispose of any other significant investments.

A.2. Joint arrangements

The Group assesses rights and obligations agreed to by the parties to a joint arrangement and, when relevant, other facts and circumstances in order to determine whether the joint arrangement in which it is involved is a joint venture or a joint operation.

A joint operation is a joint arrangement whereby the parties that have joint control of the arrangement have rights to the assets, and obligations for the liabilities, relating to the arrangement. Those parties are called joint operators.

Joint ventures are businesses over which Millicom exercises joint control as decisions over the relevant activities, such as the ability to upstream cash from the joint ventures, require unanimous consent of shareholders. Millicom determines the existence of joint control by reference to joint venture agreements, articles of association, structures and voting protocols of the board of directors of those ventures. Our main investment in joint ventures is comprised of Honduras.

At December 31, 2024, the equity accounted net assets of our joint venture in Honduras totaled $373 million (December 31, 2023: $382 million). These net assets do not necessarily represent statutory reserves available for distribution as these include consolidation adjustments (such as goodwill and identified assets and assumed liabilities recognized as part of the purchase accounting). Out of these net assets, $3 million (December 31, 2023: $3 million) represent statutory reserves that are unavailable to be distributed to the Group. During the year ended December 31, 2024, Millicom's joint venture in Honduras repatriated cash of $89 million under different forms (December 31, 2023: $86 million).

At December 31, 2024, Millicom had $133 million payable to Honduras joint venture which were mainly comprised of advances and cash pool balances (December 31, 2023: $68 million). In addition, as of December 31, 2024, Millicom had a total receivable from Honduras joint venture of $12 million, (December 31, 2023: $9 million) mainly corresponding to other operating receivables.

Our main joint ventures are as follows:

Telefonica Celular S.A. (i)

Honduras

Mobile, MFS

66.7

(i)Millicom owns more than 50% of the shares in these entities and has the right to nominate a majority of the directors of each of these entities. However, key decisions over the relevant activities must be taken by a super majority vote. This effectively gives either shareholder the ability to veto any decision and therefore neither shareholder has sole control over the entity. Therefore, the operations of these joint ventures are accounted for under the equity method.

The carrying values of Millicom’s investments in joint ventures were as follows:

F-24


Notes to the Consolidated Financial Statements For the years ended December 31, 2024, 2023 and 2022

A.2.1. Accounting for joint arrangements

Joint ventures are accounted for using the equity method of accounting and are initially recognized at cost (calculated at fair value if it was a subsidiary of the Group before becoming a joint venture). The Group’s investments in joint ventures include goodwill (net of any accumulated impairment loss) on acquisition.

The Group’s share of post-acquisition profits or losses of joint ventures is recognized in the consolidated statement of income and its share of post-acquisition movements in reserves is recognized in reserves. Cumulative post-acquisition movements are adjusted against the carrying amount of the investments. When the Group’s share of losses in a joint venture equals or exceeds its interest in the joint venture, including any other unsecured receivables, the Group does not recognize further losses, unless the Group has incurred obligations or made payments on behalf of the joint ventures.

Gains on transactions between the Group and its joint ventures are eliminated to the extent of the Group’s interest in the joint ventures. Losses are also eliminated unless the transaction provides evidence of an impairment of the asset transferred. Accounting policies of joint ventures have been changed where necessary to ensure consistency with the policies adopted by the Group. Dilution gains and losses arising in investments in joint ventures are recognized in the statement of income.

After application of the equity method, including recognizing the joint ventures’ losses, the Group applies IAS 36 to determine whether it is necessary to recognize any additional impairment loss with respect to its net investment in the joint venture.

A joint operator shall recognize in relation to its interest in a joint operation: (a) its assets, including its share of any assets held jointly; (b) its liabilities, including its share of any liabilities incurred jointly; (c) its revenue from the sale of its share of the output arising from the joint operation; (d) its share of the revenue from the sale of the output by the joint operation; and (e) its expenses, including its share of any expenses incurred jointly”

Joint Operations - Colombia

As further described in Note E.4.2. , on February 26, 2024, Tigo Colombia and Telecomunicaciones S.A. ESP BIC signed a binding framework agreement for the implementation of a single mobile access network as well as for sharing the radioelectric spectrum usage permits, whose only users would be the two shareholders participating in the such agreement. The transaction closed on December 20, 2024, with the approval from the Ministry of Information Technology and Communications to transfer in favor of the Temporary Union the permit for the access, use and exploitation of 20 MHz of radioelectric spectrum for the operation of land mobile radiocommunication services in the national territory granted to Colombia Móvil in the Resolution #332 dated February 20, 2020. Simultaneously, both operators contributed their RAN assets to UNIRED, the vehicle established to operate and maintain the unified mobile access network

The following table summarizes the contributions made by Tigo Colombia and the subsequent recognition of its participation in the joint operation's assets and liabilities:

A.2.3. Impairment of investment in joint ventures

While no impairment indicators were identified for the Group’s investments in joint ventures in 2024, according to its policy, management has completed an impairment test for its joint venture in Honduras.

The Group’s investments in Honduras operations was tested for impairment by assessing the recoverable amount (using a value in use model based on discounted cash flows) against the carrying amount. The cash flow projections used were extracted from financial budgets approved by management (refer to note E.1.6. for further details on impairment testing). Cash flows beyond this period have been extrapolated using a perpetual growth rate of 1% (2023: 1%). Discount rate used in determining recoverable amount was 9.4% (2023: 11.0%).

For the years ended December 31, 2024 and 2023, and as a result of the impairment testing described above, management concluded that the Group’s investments for its joint venture in Honduras should not be impaired.

Sensitivity analysis was performed on key assumptions within the impairment tests. The sensitivity analysis determined that sufficient headroom exists from realistic changes to the assumptions that would not impact the overall results of the testing.

A.3. Investments in associates

Millicom has significant influence over MKC Brillant Holding GmbH (LIH). Millicom’s 35.0% investment in LIH had been fully impaired in two stages (by $40 million in 2016 and $48 million in 2017) as a result of the annual impairment test conducted back then. The impairment test performed in 2024 confirmed this conclusion. The Group accounts for associates in the same way as it accounts for joint ventures, that is, using the equity method.

In December 2022, Millicom relinquished its seat at the board of directors of Milvik AB ("Milvik") and therefore lost its significant influence in accordance with IAS 28. As a result, the Group stopped equity accounting for its investment in Milvik and classified it as a financial asset measured at fair value in accordance with IFRS 9. During 2023, the Group's investment in Milvik has been disposed of for one US dollar.

A.4. Discontinued operations

A.4.1. Classification of discontinued operations

Discontinued operations are those which have identifiable operations and cash flows (for both operating and management purposes) and represent a major line of business or geographic area which has been disposed of, or are held for sale. Revenue and expenses associated with discontinued operations are presented retrospectively in a separate line in the consolidated statement of income.

A.4.2. Millicom’s discontinued operations

In accordance with IFRS 5, financial information relating to discontinued operations for the years ended December 31, 2022 is set out below. Figures shown below are after intercompany eliminations. As further explained in Note A.1.3. , the Group’s former businesses in Tanzania (sold on April 5, 2022) had been classified as discontinued operations. For the years ended December 31, 2024 and December 31, 2023, the results from discontinued operations relate to operating expense for $3 million and operating income of $4 million, respectively. For further details on Assets held for sale, refer to note E.4.

B. Performance

B.1. Revenue

Millicom’s revenue comprises sale of services from its mobile business (including Mobile Financial Services - MFS) and its fixed and other services, as well as related devices and equipment. Recurring revenue consists of monthly subscription fees, airtime and data usage fees, interconnection fees, roaming fees, TV services, B2B contracts, MFS commissions and fees from other telecommunications services such as data services, short message services and other value added services. See section B.3. for details.

B.1.1. Accounting for revenue

Revenue is recognized at an amount that reflects the consideration to which the Group expects to be entitled in exchange for transferring goods or services to a customer.

The determination of whether or not the Group acts as principal or as an agent, when there is one or several performance obligations and the determination of the standalone selling price for contracts that involve more than one performance obligation may require significant judgment, such as when the selling price of a good or service is not readily observable. The Group determines the standalone selling price of each performance obligation in the contract in accordance to the prices that the Group would apply when selling the same services and/or telephone and equipment included in the obligation to a similar customer on a standalone basis. When standalone selling price of services and/or telephone and equipment are not directly observable, the Group maximizes the use of external input and uses the expected cost plus margin approach to estimate the standalone selling price.

The Group applies the following practical expedients foreseen in IFRS 15:

•No financial component adjustment to the transaction price whenever the period between the transfer of a promised good or service to a customer and the associated payment is one year or less; when the period is more than one year the financing component is adjusted, if material.

F-28


Notes to the Consolidated Financial Statements For the years ended December 31, 2024, 2023 and 2022

•Disclosure of the transaction price allocated to unsatisfied performance obligations only for contracts that have an original expected duration of more than one year (e.g. unsatisfied performance obligations for contracts that have an original duration of one year or less are not disclosed).

•If the consideration from a customer corresponds to the value of the entity’s performance obligation to the customer (i.e, if billing corresponds to accounting revenue), the price allocated to unsatisfied performance obligations is not disclosed.

•Recognition of the incremental costs of obtaining a contract as an expense when incurred, if the amortization period of the asset that otherwise would have been recognized is one year or less.

A summary of the timing for revenue recognition from contracts with customers, is disclosed in Note B.3. and further detailed below.

Post-paid connection fees are derived from the payment of a non-refundable / one-time fee charged to customer to connect to the network (e.g. connection / installation fee). Usually,they do not represent a distinct good or service and do not give rise to a separate performance obligation and therefore revenue is recognized over the minimum contract duration. If the fee is paid by a customer without having to pay this fee again over his tenure with the Group (e.g. the customer can readily extend his contract without having to pay the same fee again), it is accounted for as a material right with revenue recognized over the customer retention period.

Post-paid mobile / cable subscription fees are recognized over the relevant enforceable/subscribed service period (recurring monthly access fees that do not vary based on usage). The service provision is usually considered as a series of distinct services that have the same pattern of transfer to the customer. Remaining unrecognized subscription fees, which are not refunded to the customers, are fully recognized once the customer has been disconnected. Customer premise equipment (CPE), provided to customers as a prerequisite to receive the subscribed Home services until return at the end of the contract duration, do not provide benefit to the customer on their own as they do not give rise to separate performance obligations and therefore are accounted for as part of the service provided to the customers.

Bundled offers are considered arrangements with multiple deliverables or elements, which can lead to the identification of separate performance obligations. Revenue is recognized in accordance with the transfer of goods or services to customers in an amount that reflects the relative transaction price of the performance obligation.

Prepaid scratch / SIM cards are services where customers purchase a specified amount of airtime or other credit in advance. Revenue is recognized as the credit is used. Unused credit is carried in the statement of financial position as a contract liability, upon expiration of the validity period (when the portion of the contract liability relating to the expiring credit is recognized as revenue as there is no longer an obligation to provide those services).

Principal-Agent, some arrangements involve two or more unrelated parties that contribute to providing a specified good or service to a customer. In these instances, the Group determines whether it has promised to provide the specified good or service itself (as a principal) or to arrange for those specified goods or services to be provided by another party (as an agent). For example, performance obligations relating to services provided by third-party content providers (i.e., mobile Value Added Services or “VAS”) or service providers (i.e., wholesale international traffic) where the Group neither controls a right to the provider’s service nor controls the underlying service itself are presented net because the Group is acting as an agent. The Group generally acts as a principal for other types of services where the Group is the primary obligor of the arrangement. In cases the Group determines that it acts as a principal, revenue is recognized in the gross amount, whereas in cases the Group acts as an agent revenue is recognized in the net amount.

Revenue from provision of Mobile Financial Services (MFS), such as commissions on peer to peer transfers, is generally recognized once the primary service has been provided to the customer. Revenue from interest earned on loans granted to customers are recognised over the period of the loan and are based on effective interest rates, with loan origination fees being treated as an adjustment to the effective interest rate.

Telephone and equipment sales are recognized as revenue once the customer obtains control of the good, that is, when the customer has the ability to direct the use and obtain substantially all of the remaining benefits from that good.

Revenue from the sale of cables, fiber, wavelength or capacity contracts, when part of the ordinary activities of the operation, is recognized as recurring revenue. Revenue is recognized when the cable, fiber, wavelength or capacity has been delivered to the customer, based on the amount expected to be received from the customer.

Revenue from operating lease of tower space is recognized on a straight-line basis over the term of the underlying lease contracts. For Finance leases, interest income and the amortization of the lease receivable, equivalent to the net investment in the lease, are recognized over the lease term.

B.2. Expenses

The various costs and expenses incurred by the Group can be summarized as presented below. The Group recognizes and categorizes expenses by their nature as either 'equipment, programming and other direct costs' which are those more directly related to the generation of revenue or as '(Other) operating expenses and income' which are rather indirect costs. As a result, 'equipment, programming and other direct costs' specifically excludes the following costs/expense which are further detailed below and elsewhere in the consolidated financial statements:

•'Operating expenses, net' further detailed below;

•Depreciation and amortization, which are further detailed in Notes E.1.3.. ‘Movements in intangible assets’, E.2.2. ‘Movements in tangible assets’ and E.3. ‘Right of use assets’.

B.3. Segmental information

As further detailed in the Introduction note, Millicom operates in a single region (Latin America), and more specifically in the following countries: Guatemala, Colombia, Panama, Honduras, Bolivia, Paraguay, El Salvador, Nicaragua and Costa Rica.

During the latter half of 2023, Millicom implemented significant organizational changes to focus on driving profitable growth with a leaner corporate structure. The Group also adopted a decentralized approach to streamline decision-making processes and enhance agility to improve profitability and shareholder value. Following these organizational changes, and considering the information being reviewed by the 'Chief Operating Decision Maker' ("CODM") to assess performance and allocate resources, Millicom's operating segments were redefined to align with its countries of operation.

During the third quarter of 2024, Millicom announced several organizational changes aimed at strengthening its connection with each country. With the appointment of a new Chief Executive Officer (CEO), the Group has streamlined its structure, ensuring that all General Managers of operations and Group Leadership team members report directly to him. The Chief Executive Officer (CEO) together with the Group Chief Financial Officer (CFO) and the Chief Technology & Information Officer (CTIO) form the ‘Chief Operating Decision Maker’ (“CODM”).

Millicom´s CODM assesses performance and allocates resources, based on individual countries, which are its operating segments. The Honduras joint venture is reviewed by the CODM in a similar manner as for the Group’s controlled operations and is therefore also shown as a separate operating segment at 100%. However, these amounts are subsequently eliminated in order to reconcile with the Group consolidated numbers, as shown in the reconciliations below.

Management evaluates performance and makes decisions about allocating resources to the Group's operating segments based on financial measures, such as revenue, including service revenue, and EBITDA. Capital expenditures are also a significant aspect for management and in the telecommunication industry as a whole. Management believes that service revenue and EBITDA are essential financial indicators for the CODM and investors. These measures are particularly valuable for evaluating performance over time. Management utilizes service revenue and EBITDA when making operational decisions, allocating resources, and conducting internal comparisons against historical performance and competitor benchmarks. Additionally, these metrics provide deeper insights into the Group's operating performance. Millicom's Compensation and Talent Committee also employs service revenue and EBITDA when assessing employees' performance and compensation, including that of the Group's executives. A reconciliation of service revenue to revenue and EBITDA to profit before taxes is provided below.

Capital expenditures are reconciled with notes E.1. and E.2..

Revenue, Service revenue, EBITDA, capital expenditures and other segment information for the years ended December 31, 2024, 2023 and 2022, are shown on the below:

Restructuring Costs

During 2024 and 2023, Millicom carried out cost reduction projects, with a focus on efficiency improvements; the Group recorded in 2024 $115 million of the above mentioned as severance costs (2023: $87 million), of which $94 million are presented as "Wages and salaries" (2023: $78 million) and $21 million as "Share based compensation" (2023: $9 million).

On September 19, 2024, Millicom announced that Mauricio Ramos stepped down from his roles as Director and Executive Chairman of the Board. A separation agreement was signed; this agreement provided for the immediate vesting of all unvested share plans, modified on September 30, 2024, to be paid in cash, with the entire amount of the separation agreement paid in 2024. In line with IFRS 2, shares acceleration component are treated as an early settlement and recognized immediately as employee related costs in the Statement of Income and as share-based compensation in the Statement of Changes in Equity. The portion associated with the shares cancellation was reflected in the Statement of Changes in Equity and in the Statement of Cash Flows.

B.4.1. Share-based compensation

1.Equity-settled

Millicom shares granted to management and key employees includes share-based compensation in the form of long-term share incentive plans. Since 2016, Millicom has two types of annual plans: a Deferred Share Plan (DSP) and a Performance Share Plan (PSP). The different plans are further detailed below.

Cost of share-based compensation

Deferred Share Plan

Shares vest at a rate of 30% on the first three-months of each of year one and two, and the remaining 40% on the first three-months of year three. Vesting is conditional upon the participant remaining employed with Millicom at each vesting date. The cost of this long-term incentive plan, which is not conditional on performance conditions, is calculated as follows: Fair value (share price) of Millicom’s shares at grant date x number of shares expected to vest.

F-34


Notes to the Consolidated Financial Statements For the years ended December 31, 2024, 2023 and 2022

Performance Share Plan

Shares granted under these PSPs vest at the end of the three-year period, subject to performance conditions.

The Operating Cash Flow after Leases (“OCFaL”) and Service Revenue peformance conditions are based on the achievement of the OCFaL/Service Revenue targets measured on a 3-year actual cumulative achievement against the 3-year cumulative targets.The Relative TSR is measured over the 10 trading days before / after December 31 of the last year of the corresponding three-year measurement period. The 2024 PSP ESG metric is based on Carbon Emissions reduction targets; while the 2023 PSP ESG metric is based on five ESG metrics: 1. Female % of Total Employees ; 2. Female % of Leadership; 3. Progress toward established SBTi targets; 4. Women and girls trained as part of our Conectadas Program; 5. Teachers trained as part of our Maestr@sConectad@s program.

Performance Share Plan (for plans issued from 2024)

Shares granted under this 2024 PSP generally follow the same rules as for the ones of previous years.

The 2024 PSP plan is divided in three equity vehicles: 60% based on Stock Appreciation Rights ("SARs"), 30% based on Restricted Stock Units ("RSUs") and 10% based on Performance shares based on achievement of the ESG performance measure between 2024 and 2026. SARs are calculated based on Black-Scholes valuation of the stock price at fair market value of the grant and will vest in number of units. The participant will have the eligibility to exercise these units during the seven-year period following the vesting date.

Performance Share Plan (for plans issued from 2021 up to 2023)

The 2023 and 2022 plans are based on the following metrics: OCFaL (50%); Service Revenue (30%); Relative Total Shareholder Return (“Relative TSR”) (2023: 10%, 2022: 20%). The 2023 PSP has an Environmental, Social and Governance metric ("ESG") (10%), The 2021 PSP is 35% based on RSUs; 30% on OCFaL; 15% based on Service Revenue and 20% on Relative TSR.

Assumptions and fair value of the shares under the TSR and SAR portion(s)

For the PSPs, and in order to calculate the fair value of the TSR portion of those plans, it is necessary to make a number of assumptions which are set out below. The assumptions have been set based on an analysis of historical data as at grant date.


	Risk-free rate %	Dividend yield %	Share price volatility(i) %	Award term (years)	Share fair value (in US$)
Performance Share Plan 2023 (Relative TSR)	4.66	—	52.88	2.82	31.13
Performance Share Plan 2022 (Relative TSR)	2.01	—	47.94	2.80	29.12
Performance Share Plan 2021 (Relative TSR)	0.29	1.28	46.28	2.82	52.99

(i) Historical volatility retained was determined on the basis of a three-year historic average.

For the PSPs, and in order to calculate the fair value of the SAR portion of the plan, it is necessary to make a number of assumptions which are set out below. The assumptions have been set based on an analysis of historical data as at grant date.


	Risk-free rate %	Dividend yield %	Share price volatility(i) %	Award term (years)	Unit fair value (in US$)
Performance share plan 2024 (SAR)	4.31	—	38.20	6.50	9.35

The cost of the long-term incentive plans which are conditional on market conditions is calculated as follows: Fair value (market value) of shares / SAR units at grant date (as calculated above) x number of shares / SAR units expected to vest.

The cost of these plans is recognized, together with a corresponding increase in equity (equity settled transaction reserve), over the period in which the performance and/or employment conditions are fulfilled, ending on the date on which the relevant employees become fully entitled to the award. Adjustments are made to the expense recorded for forfeitures, mainly due to management and employees leaving Millicom. Non-market performance conditions are not taken into account when determining the grant date fair value of awards, but the likelihood of the conditions being met is assessed as part of the Group’s best estimate of the number of equity instruments that will ultimately vest.

No expense is recognized for awards that do not ultimately vest, except for awards where vesting is conditional upon a market condition (such as the Relative TSR and SAR). These are treated as vested, regardless of whether or not the market conditions are satisfied, provided that all other performance conditions are satisfied. Where the terms of an equity-settled award are modified, as a minimum an expense is recognized as if the terms had not been modified. In addition, an expense is recognized for any modification that increases the total fair value of the share based payment arrangement, or is otherwise beneficial to the employee as measured at the date of modification.

2.Cash-settled

Market Stock Units

A plan based on Market Stock Units (" MSU") was awarded in 2021 as a one-time retention plan (as a consequence of the impact of COVID-19 on the Group's business) to a selected group of executives. The MSU was a performance-based scheme where the outcome was dependent on the share price at the time of vesting. The number of MSUs granted to each participant was determined on the basis of a share price at inception of $33.83 for Tranche 2022 and $36.90 for Tranche 2023 (targets consider that Millicom share price at grant date - $30.75 - would appreciate 10% for Tranche 2022 and 20% for tranche 2023 from the grant price). The aforementioned share prices and number of units granted have been amended as a result of the effect of the right offering (see note C.1. ). At the vesting date, the value of the MSU were determined by the 30-trading day average share price ended on September 30, 2022 for Tranche 2022, and the 30-trading day average share price ended on June 30, 2023 for Tranche 2023. For each Tranche, the payment was made in cash 12 months after those dates, provided the participant was still employed (subject to limited allowances for good leavers). For every participant, payment was capped at 150% of their Target MSU Award Value set up for each Tranche. Participants of the MSU plan were required to forfeit their awards under the LTI plans 2019 and 2020 in respect of the Financial targets (Service Revenue and Operating Cash flow growths), provided that the TSR component will continue to be active for these schemes. During 2024, Tranche 2023 was paid out to participants for a total cash amount of $1.74 million. (2023: Tranche 2022 was paid out to for $1.15 million).

The MSU was a cash-settled share-based payment plan and Millicom measured the services acquired over the relevant service period and the liability incurred at the fair value of the liability. Until the liability was settled, Millicom was required to remeasure the fair value of the liability at the end of each reporting period and at the date of settlement, with any changes in value recognised in the statement of income.

As of December 31, 2024 and 2023, the fair value of the liability amounts to nil and $1 million, respectively, and was determined by using Millicom's share price (using a Black-Scholes model would not result in material differences). The related cost for the years ended December 31, 2024 and 2023, amounted to an expense of $0.6 million and of $1 million, respectively.

B.4.2. Pension and other long-term employee benefit plans

Pension plans

The pension plans apply to employees who meet certain criteria (including years of service, age and participation in collective agreements).

F-36


Notes to the Consolidated Financial Statements For the years ended December 31, 2024, 2023 and 2022

Pension and other similar employee related obligations can result from either defined contribution plans or defined benefit plans. A defined contribution plan is a pension plan under which the Group pays fixed contributions into a separate entity and no further payment obligations exist once the contributions have been paid. The contributions are recognized as employee benefit expenses when they are due. Prepaid contributions are recognized as assets to the extent that a cash refund or a reduction in future payments is available.

Defined benefit pension plans define an amount of pension benefit that an employee will receive on retirement, usually dependent on one or more factors such as age, years of service and compensation. The liability recognized in the statement of financial position in respect of the defined benefit pension plan is the present value of the defined benefit obligation at the statement of financial position date less the fair value of plan assets, together with adjustments for unrecognized actuarial gains or losses and past service costs. The defined benefit obligation is calculated annually by independent actuaries. The present value of the defined benefit obligation is determined by discounting the estimated future cash outflows, using an appropriate discount rate based on maturities of the related pension liability. Re-measurement of net defined benefit liabilities are recognized in other comprehensive income and not reclassified to the statement of income in subsequent years. Past service costs are recognized in the statement of income on the earlier of the date of the plan amendment or curtailment, and the date that the Group recognizes related restructuring costs. Net interest is calculated by applying the discount rate to the net defined benefit asset/liability.

Long-service plans

Long-service plans apply for Colombian subsidiary UNE employees with more than five years of service whereby additional bonuses are paid to employees that reach each incremental length of service milestone (from five to 40 years).

Termination plans

UNE has a number of employee defined benefit plans. The level of benefits provided under the plans depends on collective employment agreements and Colombian labor regulations. There are no defined assets related to the plans, and UNE make payments to settle obligations under the plans out of available cash balances.

At December 31, 2024, the defined benefit obligation liability amounting to $44 million (2023: $51 million), decreased mainly related to currency translation effect ($7 million). Payments expected in the plans in future years totals $82 million (2023: $100 million). The average duration of the defined benefit obligation at December 31, 2024 is 4 years (2023: 4 years). The termination plans apply to employees that joined UNE prior to December 30, 1996. The level of payments depends on the number of years in which the employee has worked before retirement or termination of their contract with UNE.

Except for the UNE pension plan described above, there are no other material defined benefits plans in the Group.

B.4.3. Directors and executive management

The remuneration of the members of the Board of Directors comprises an annual fee and shares. Director remuneration is proposed by the Nomination Committee and approved by the shareholders at their Annual General Meeting (AGM).

B.6. Taxation

B.6.1. Income tax expense

Tax mainly comprises income taxes of subsidiaries and withholding taxes (on intra-group dividends, management fees and royalties for use of Millicom trademarks and brands). Millicom operations are in jurisdictions with income tax rates of 10% to 35% levied on either revenue or profit before income tax (2023: 10% to 35%; 2022: 10% to 35%). Income tax relating to items recognized directly in equity is also recognized in equity.

Effective tax rate	50.9%		51.2%	242.3%		236.9%	93.3%		63.6%

Tax expense decreases from December 31, 2023, is mainly due to the impairment of tax credits and deferred tax assets in Colombia in 2023, resulting from the application of IAS12 over their recognition partially offset by higher profitability.

B.6.2. Current tax assets and liabilities

Current tax assets and liabilities for current and prior periods are measured at the amount expected to be recovered from or paid to the taxation authorities. The tax rate and tax laws used to compute the amount are those enacted or substantively enacted by the statement of financial position date.

B.6.3. Deferred tax

Deferred tax is calculated using the liability method on temporary differences at the statement of financial position date between the tax base of assets and liabilities and their carrying amount for financial reporting purposes.

Deferred tax liabilities are recognized for all taxable temporary differences, except where the deferred tax liability arises from the initial recognition of goodwill or of an asset or liability in a transaction that is not a business combination and, at the time of the transaction, affects neither accounting, nor taxable profit or loss.

Deferred tax assets are recognized for all temporary differences including unused tax credits and tax losses, to the extent that it is probable that taxable profit will be available against which the deductible temporary differences can be utilized, except where the deferred tax assets relate to deductible temporary differences from initial recognition of an asset or liability in a transaction that is not a business combination, and, at the time of the transaction, affects neither accounting, nor taxable profit or loss. It is probable that taxable profit will be available when there are sufficient taxable temporary differences relating to the same tax authority and the

F-40


Notes to the Consolidated Financial Statements For the years ended December 31, 2024, 2023 and 2022

same taxable entity which are expected to reverse in the same period as the expected reversal of the deductible temporary difference.

The carrying amount of deferred tax assets is reviewed at each statement of financial position date and reduced to the extent that it is no longer probable that sufficient taxable profit will be available to utilize them. Unrecognized deferred tax assets are reassessed at each statement of financial position date and are recognized to the extent it is probable that future taxable profit will enable the asset to be recovered.

Deferred tax assets and liabilities are measured at the tax rate expected to apply in the year when the assets are realized or liabilities settled, based on tax rates and tax laws that have been enacted or substantively enacted at the statement of financial position date. Deferred tax assets and deferred tax liabilities are offset where legally enforceable set off rights exist and the deferred taxes relate to the same taxable entity and the same taxation authority.

The aforementioned tax losses have not been recognized due to the remote possibility of utilizing all or portion of the total amount available in application of IAS 12.

With effect from 2017, Luxembourg tax losses incurred may be carried forward for a maximum of 17 years. Losses incurred before 2017 may be carried forward without limitation of time.

MICSA is the head of a fiscal unity in Luxembourg, which has an estimated amount of unrecognized tax losses as of December 31, 2024 of $4.8 billion. Per Luxembourg tax law, approximately $1.4 billion expire 17 years after generation, approximately $3.4 billion do not expire.

At December 31, 2024, Millicom had $803 million of unremitted earnings of Millicom operating subsidiaries for which no deferred tax liabilities were recognized (2023: $672 million; 2022: $640 million). Except for intragroup dividends to be paid out of 2024 profits in 2025 for which deferred tax of $44 million (2023: $26 million; 2022 $25 million) has been provided, it is anticipated that intra-group dividends paid in future periods will be made out of profits of future periods.

B.7. Earnings per share

Basic earnings (loss) per share are calculated by dividing net profit for the year attributable to equity holders of the Company by the weighted average number of ordinary shares outstanding during each year.

Diluted earnings (loss) per share are calculated by dividing the net profit for the year attributable to equity holders of the Company by the weighted average number of ordinary shares outstanding during each year, plus the weighted average number of dilutive potential shares.

Earnings (loss) per common share for profit (loss) for the period attributable to owners of the Company	1.46	(0.48)	1.27

(i) For the purpose of calculating the diluted earnings (loss) per common share, the weighted average outstanding shares used for the basic earnings (loss) per common share were increased only by the portion of the shares which have a dilutive effect on the earnings (loss) per common share. As a result, for years in which the Group has reported net loss, diluted net loss per share is the same as the basic net loss per share, because dilutive ordinary shares are not assumed to have been issued if their effect is anti-dilutive. Accordingly, 1,433 thousand potential ordinary shares as a result of share-based compensation plans were not considered in 2023 EPS as their impact was anti-dilutive.

C. Capital structure and financing

C.1. Share capital, share premium and reserves

Common shares are classified as equity. Incremental costs directly attributable to the issue of new shares are shown in equity as a deduction from the proceeds.

Where any Group company purchases the Company’s share capital, the consideration paid, including any directly attributable incremental costs, is shown under Treasury shares and deducted from equity attributable to the Company’s equity holders until the shares are canceled, reissued or disposed of. Where such shares are subsequently sold or reissued, any consideration received, net of any directly attributable incremental costs and the related income tax effects is included in equity attributable to the Company’s equity holders.

On May 18, 2022, the Board of Directors of Millicom resolved on a rights offering (the "Rights Offering") granting preferential subscription rights to existing holders of shares and Swedish Depositary Receipts ("SDRs") to subscribe for up to 70,357,088 shares in aggregate. The result of the Rights Offering showed that 68,822,675 shares, including those represented by SDRs, have been subscribed for by the exercise of basic subscription rights. The remaining 1,534,413 shares, including those represented by SDRs, were allotted to those investors who subscribed for them pursuant to over subscription privileges. The Rights Offering was thus fully subscribed, and Millicom received proceeds amounting to approximately $717 million after deducting underwriting commissions and other offering expenses of $28 million.

As a result, the Rights Offering resulted in the issuance of 70,357,088 new shares, which increased the number of outstanding shares in Millicom from 101,739,217 to 172,096,305. The share capital also increased by $106 million to $258 million from $153 million. The remaining $611 million had been allocated to the Group's share premium account.

Notes to the Consolidated Financial Statements For the years ended December 31, 2024, 2023 and 2022

C.1.1. Legal reserve

If Millicom International Cellular S.A. reports an annual net profit on a non-consolidated basis, Luxembourg law requires appropriation of an amount equal to at least 5% of the annual net profit to a legal reserve until such reserve equals 10% of the issued share capital. This reserve is not available for dividend distribution. In 2024, the AGM approved an allocation of the 2023 results to the legal reserve for an amount of $7.6 million in 2023, the AGM approved an allocation to the legal reserve for an amount of $1.9 million.

C.1.2. Equity settled transaction reserve

The cost of long-term share incentive plans ("LTIPs ")is recognized as an increase in the equity-settled transaction reserve over the period in which the performance and/or service conditions are rendered. When shares under the LTIPs vest and are issued the corresponding reserve is transferred to share premium.

C.1.3. Hedge reserve

The effective portions of changes in value of cash flow hedges are recorded in the hedge reserve (see note C.1. ).

C.1.4. Currency translation reserve

The currency translation reserve includes foreign exchange gains and losses arising from translations of subsidiaries (joint ventures and associates) with functional currencies different to US dollar. Their relevant financial position captions are translated to US dollars using the closing exchange rate; while their relevant statement of income captions are translated to US dollars at monthly average exchange rates during the year. When the Group disposes of or loses control or significant influence over a foreign operation, exchange differences that were recorded in equity are recognized in the consolidated statement of income as part of gain or loss on sale or loss of control and/or significant influence.

C.2. Dividend distributions

On November 29, 2024, Millicom' Board has approved an interim dividend of $1.00 per share (or its equivalent in SEK per SDR), i.e. approximately $172 million paid on January 10, 2025. No dividend distributions were made in 2023 and 2022 as the Group pivoted its shareholder's remuneration strategy to share buybacks.

In addition, the ability of the Company to make dividend payments is subject to, among other things, the terms of indebtedness, legal restrictions and the ability to repatriate funds from Millicom’s various operations. At December 31, 2024, $562 million (December 31, 2023: $491 million; December 31, 2022: $472 million) of Millicom’s retained profits represent statutory reserves that are unavailable to be distributed to owners of the Company.

Debt and financing are initially recognized at fair value, net of directly attributable transaction costs. They are subsequently measured at amortized cost using the effective interest rate method. Amortized cost is calculated by taking into account any discount or premium on acquisition and any fees or costs that are an integral part of the effective interest rate. Any difference between the initial amount and the maturity amount is recognized in the consolidated statement of income over the period of the borrowing.

Right of set-off and derecognition

Financial assets and financial liabilities are offset and the net amount is reported in the consolidated statement of financial position if there is a currently enforceable legal right to offset the recognized amounts and an intention to settle on a net basis, or to realize the assets and settle the liabilities simultaneously.

A financial asset (or a part of a financial asset or part of a group of similar financial assets) is derecognized when:

• Rights to receive cash flows from the asset have expired; or

• Rights to receive cash flows from the asset have been transferred to a third party or the Group has retained the contractual rights to receive the contractual rights to receive the cash flows from the asset, but has assumed a contractual obligation to pass those cash flows under a “pass-through” arrangement.

When rights to receive cash flows from an asset have been transferred or a pass-through arrangement concluded, an evaluation is made if and to what extent the risks and rewards of ownership have been retained. When the Group has neither transferred nor retained substantially all of the risks and rewards of the asset, nor transferred control of the asset, the asset is recognized to the extent of the Group’s continuing involvement in the asset. In that case, the Group also recognizes an associated liability. The transferred asset and the associated liability are measured on a basis that reflects the rights and obligations that the Group has retained. Continuing involvement that takes the form of a guarantee over the transferred asset is measured at the lower of the original carrying amount of the asset and the maximum amount of consideration that the Group could be required to repay.

A financial liability is derecognized when the obligation under the liability is discharged or canceled, or expires. When an existing financial liability is replaced by another from the same lender on substantially different terms, or the terms of an existing liability are substantially modified, such an exchange or modification is treated as the derecognition of the original liability and the recognition of a new liability. The difference in the respective carrying amounts is recognized in the statement of income.

C.3.3. Interest and other financial expenses

The Group’s interest and other financial expenses comprised the following:

C.3.4. Guarantees and pledged assets

Guarantees

Financial guarantee contracts issued by the Group are those contracts that require a payment to be made to reimburse the holder for a loss it incurs because the specified debtor fails to make payment when due in accordance with the terms of a debt instrument. Financial guarantee contracts are recognized initially as a liability at fair value, adjusted for transaction costs that are directly attributable to the issuance of the guarantee. Subsequently, the liability is measured at the higher of the best estimate of the expenditure required to settle the present obligation at the reporting date and the amount recognized, less cumulative amortization.

Liabilities to which guarantees are related are recorded in the consolidated statement of financial position under Debt and financing, and liabilities covered by supplier guarantees are recorded under Trade payables or Debt and financing, depending on the underlying terms and conditions.

Pledged assets

As at December 31, 2024, the Group’s share of total debt and financing secured by either pledged assets, pledged deposits issued to cover letters of credit, or guarantees issued was $232 million (December 31, 2023: $505 million). At December 31, 2024 there were no pledged deposits (2023: $6 million) by the Group over these debts and financings. The remainder represented primarily guarantees issued by Millicom S.A. to guarantee financings raised by other Group operating entities.

C.3.5. Covenants

Millicom’s financing facilities are subject to a number of covenants including net leverage ratio, debt service coverage ratios, or debt to earnings ratios, among others. In addition, certain of its financings contain restrictions on sale of businesses or significant assets within the businesses. At December 31, 2024, there were no breaches of financial covenants and we do not anticipate any such breaches in the next twelve months after the reporting period.

C.4. Lease liabilities

At December 31, 2024, lease liabilities are presented in the statement of financial position as follows:

Current	156	189

Total Lease liabilities	954	1,043

As permitted under IFRS 16, Millicom has elected not to recognize a lease liability for short term leases (leases with an expected term of 12 months or less) or for leases of low value assets. Payments associated with short-term leases of equipment and vehicles and all leases of low-value assets are rather recognized on a straight-line basis as an expense in the statement of income. Short-term leases are leases with a lease term of 12 months or less. Low-value assets comprise IT equipment and small items of office furniture. In addition, certain variable lease payments are not permitted to be recognized as lease liabilities and are expensed as incurred.

The total cash outflow for leases in 2024 was $324 million (2023: $292 million; 2022: $285 million). Lease liabilities split by maturity and future cash outflows are disclosed in note D.5..

At December 31, 2024, the Group has not committed to any material leases which had not yet commenced and has no material lease contracts with variable lease payments.

The Group's leasing activities and how these are accounted for

The Group leases various lands, sites, towers (including those related to towers sold and leased back), offices, warehouses, retail stores, equipment and cars. Rental contracts are typically made for fixed periods but may have extension options as described below. Lease terms are negotiated on an individual basis and contain a wide range of different terms and conditions. The lease agreements do not impose any covenants, but leased assets may not be used as security for borrowing purposes.

Leases are recognized as a right-of-use asset and a corresponding liability at the date at which the leased asset is available for use by the Group. Each lease payment is allocated between the reduction of the liability and finance cost. The finance cost is charged to the statement of income over the lease period so as to produce a constant periodic rate of interest on the remaining balance of the liability for each period. The right-of-use asset is depreciated over the shorter of the asset's useful life and the lease term on a straight-line basis.

Assets and liabilities arising from a lease are initially measured on a present value basis. Lease liabilities include the net present value of the following lease payments:

•fixed payments (including in-substance fixed payments), less any lease incentives receivable

•variable lease payment that are based on an index or a rate

•amounts expected to be payable by the lessee under residual value guarantees

•the exercise price of a purchase option if the lessee is reasonably certain to exercise that option, and

•payments of penalties for terminating the lease, if the lease term reflects the lessee exercising that option.

The lease payments are discounted using the interest rate implicit in the lease. As it is generally impracticable to determine that rate, the Group uses the lessee’s incremental borrowing rate, being the rate that the lessee would have to pay to borrow the funds necessary to obtain an asset of similar value in a similar economic environment with similar terms and conditions. The incremental borrowing rate applied can have a significant impact on the net present value of the lease liability recognized under IFRS 16.

The Group determines the incremental borrowing rate by country and by considering the risk-free rate, the country risk, the industry risk, the credit risk and the currency risk, as well as the lease and payment terms and dates.

The Group is also exposed to potential future increases in variable lease payments based on an index or rate, which are not included in the lease liability until they take effect. When adjustments to lease payments based on an index or rate take effect, the lease liability is adjusted against the right-of-use asset by discounting the revised lease payments using either the initial discount rate or a revised discount rate. The initial discount rate is used if future lease payments are reflecting market or index rates or if they are in substance fixed. The discount rate is revised, if a change in floating interest rates occurs. The Group reassesses the variable payment only when there is a change in cash flows resulting from a change in the reference index or rate and not at each reporting date.

According to IFRS 16, lease term is defined as the non-cancellable period for which a lessee has the right to use an underlying asset, together with both: (a) periods covered by an option to extend the lease if the lessee is reasonably certain to exercise that option; and (b) periods covered by an option to terminate if the lessee is reasonably certain not to exercise that option. The assessment of such options is performed at the commencement of a lease. As part of the assessment, Millicom introduced the 'time horizon

F-55


Notes to the Consolidated Financial Statements For the years ended December 31, 2024, 2023 and 2022

concept': the reasonable term under which the company expects to use a leased asset considering economic incentives, management decisions, business plans and the fast-paced industry Millicom operates in. The assessment must be focused on the economic incentives for Millicom to exercise (or not) an option to early terminate/extend a contract. The Group has decided to work on the basis the lessor will generally accept a renewal/not early terminate a contract, as there is an economic incentive to maintain the contractual relationship.

Millicom considered the specialized nature of most of its assets under lease, the low likelihood the lessor can find a third party to substitute Millicom as a lessee and past practice to conclude that, the lease term can go beyond the notice period when there is more than an insignificant penalty for the lessor not to renew the lease. This analysis requires judgment and has a significant impact on the lease liability recognized under IFRS 16.

Under IFRS 16, the accounting for sale and leaseback transactions has changed as the underlying sale transaction needs to be first analyzed using the guidance of IFRS 15. The seller/lessee recognizes a right-of-use asset in the amount of the proportional original carrying amount that relates to the right of use retained. Accordingly, only the proportional amount of gain or loss from the sale must be recognized.

Finally, the Group has taken the additional following decisions when adopting the standard:

•Non-lease components are capitalized (IFRS16.15)

•Intangible assets are out of IFRS 16 scope (IFRS16.4)

C.7. Financial instruments

i) Equity and debt instruments

Classification

The Group classifies its financial assets in the following measurement categories:

•those to be measured subsequently at fair value either through Other Comprehensive Income (OCI), or through profit or loss, and

•those to be measured at amortized cost.

The classification depends on the Group’s business model for managing the financial assets and the contractual terms of the cash flows.

F-57


Notes to the Consolidated Financial Statements For the years ended December 31, 2024, 2023 and 2022

For assets measured at fair value, gains and losses will either be recorded in profit or loss or OCI. For investments in equity instruments that are not held for trading, this will depend on whether the Group has made an irrevocable election at the time of initial recognition to account for the equity investment at fair value through other comprehensive income (FVOCI).

The Group reclassifies debt investments when and only when its business model for managing those assets changes.

Measurement

At initial recognition, the Group measures a financial asset at its fair value plus, in the case of a financial asset not at fair value through profit or loss (FVPL), transaction costs that are directly attributable to the acquisition of the financial asset. Transaction costs of financial assets carried at FVPL are expensed in profit or loss.

Financial assets with embedded derivatives are considered in their entirety when determining whether their cash flows are solely payment of principal and interest.

Debt instruments

Subsequent measurement of debt instruments depends on the Group’s business model for managing the asset and the cash flow characteristics of the asset. There are three measurement categories into which the Group classifies its debt instruments:

•Amortized cost: Assets that are held for collection of contractual cash flows where those cash flows represent solely payments of principal and interest are measured at amortized cost. Interest income from these financial assets is included in finance income using the effective interest rate method. Any gain or loss arising on derecognition is recognized directly in profit or loss and presented in other gains / (losses), together with foreign exchange gains and losses. Impairment losses are presented as a separate line item in the consolidated statement of income.

• FVOCI: Assets that are held for collection of contractual cash flows and for selling the financial assets, where the assets’ cash flows represent solely payments of principal and interest, are measured at FVOCI. Movements in the carrying amount are taken through OCI, except for the recognition of impairment gains or losses, interest revenue and foreign exchange gains and losses which are recognized in profit or loss. When the financial asset is derecognised, the cumulative gain or loss previously recognized in OCI is reclassified from equity to profit or loss and recognized in ‘Other non-operating (expenses) income, net’. Interest income from these financial assets is included in finance income using the effective interest rate method. Foreign exchange gains and losses and impairment expenses are presented as ‘Other non-operating (expenses) income, net’ in the consolidated statement of income.

• FVPL: Assets that do not meet the criteria for amortized cost or FVOCI are measured at FVPL. A gain or loss on a debt investment that is subsequently measured at FVPL is recognized in profit or loss and presented net within ‘Other non-operating (expenses) income, net’ in the period in which it arises.

Equity instruments

The Group subsequently measures all equity investments at fair value. The Group does not hold equity instruments for trading. Where the Group’s management has elected to present fair value gains and losses on equity investments in OCI, there is no subsequent reclassification of fair value gains and losses to profit or loss following the derecognition of the investment. Purchases and sales of equity instruments are recognized as of their settlement date. Dividends from such investments continue to be recognized in profit or loss as other income when the Group’s right to receive payments is established.

Otherwise, changes in the fair value of financial assets at FVPL are recognized in ‘Other non-operating (expenses) income, net’ in the consolidated statement of income as applicable.

Impairment

The Group assesses on a forward looking basis the expected credit losses associated with its financial assets carried at amortized cost and FVOCI. The impairment methodology applied depends on whether there has been a significant increase in credit risk.

For trade receivables, the Group applies the simplified approach permitted by IFRS 9, which requires expected lifetime losses to be recognized from initial recognition of the trade receivables.

The provision is recognized in the consolidated statement of income within equipment, programming and other direct costs.

The gross carrying amount of a financial asset is written off when the Group has no reasonable expectations of recovering a financial asset in its entirety or a portion thereof. The Group has a policy of writing off the gross carrying amount when the financial asset is not recoverable based on historical experience of recoveries of similar assets. The Group expects no significant recovery from the amount written off. However, financial assets that are written off could still be subject to enforcement activities in order to comply with the Group's procedures for recovery of amounts due.

ii) Derivative financial instruments and hedging activities

Derivatives are initially recognized at fair value on the date a derivative contract is entered into and are subsequently re-measured at fair value at each subsequent closing date. The method of recognizing the resulting gain or loss depends on whether the derivative is designated as a hedging instrument and, if so, the nature of the item being hedged. The Group designates certain derivatives as either:

a) Hedges of the fair value of recognized assets or liabilities or a firm commitment (fair value hedge); or

b) Hedges of a particular risk associated with a recognized asset or liability or a highly probable forecast transaction (cash flow hedge).

c) Hedges of a net investment in a foreign operation (net investment hedges).

For transactions designated and qualifying for hedge accounting, at the inception of the transaction, the Group documents the relationship between hedging instruments and hedged items, as well as its risk management objectives and strategy for undertaking various hedging transactions. This is done in reference to the Group Treasury Policy as last updated and approved by the Audit Committee in late 2024. The Group also documents its assessment, both at hedge inception and on an ongoing basis (quarterly), of whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in fair values or cash flows of hedged items.

The full fair value of a hedging instrument is classified as a non-current asset or liability when the period to maturity of the hedged item is more than 12 months and as a current asset or liability when the remaining maturity of the hedged item is less than 12 months.

The change in fair value of hedging instruments that are designed and qualify as fair value hedges is recognized in the statement of income as finance costs or income. The change in fair value of the hedged item attributable to the risk hedged is recorded as part of the carrying value of the hedged item and is also recognized in the statement of income as finance costs or income.

The effective portion of changes in the fair value of derivatives that are designated and qualify as cash flow hedges is recognized in other comprehensive income. Gains or loss relating to any ineffective portion is recognized immediately in the statement of income within Other non-operating (expenses) income, net. Amounts accumulated in equity are reclassified to the statement of income in the periods when the hedged item affects profit or loss.

Hedges of net investments in foreign operations are accounted for similarly to cash flow hedges. Any gain or loss on the hedging instrument relating to the effective portion of the hedge is recognised in other comprehensive income and accumulated in reserves in equity. The gain or loss relating to the ineffective portion is recognised immediately in profit or loss within Other non-operating (expenses) income, net. Gains and losses accumulated in equity are reclassified to profit or loss when the foreign operation is disposed of or sold.

When a hedging instrument expires or is sold, or when a hedge no longer meets the criteria for hedge accounting, any cumulative gain or loss existing in equity at that time is recycled to the statement of income within Other non-operating (expenses) income, net.

When a forecast transaction is no longer expected to occur, the cumulative gain or loss that was reported in equity is immediately transferred to the statement of income within Other non-operating (expenses) income, net.

Certain derivative instruments do not qualify for hedge accounting. Changes in the fair value of any derivative instrument that does not qualify for hedge accounting are recognised immediately in profit or loss and are included in Other non-operating (expenses) income, net.

C.7.1. Fair value measurement hierarchy

Millicom uses the following fair value measurement hierarchy:

Level 1 – Quoted prices (unadjusted) in active markets for identical assets or liabilities.

Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly (that is, as prices) or indirectly (that is, derived from prices).

Level 3 – Inputs for the asset or liability that are not based on observable market data (that is, unobservable inputs).

The Group enters into derivative financial instruments with various counterparties, principally financial institutions with investment grade ratings. Interest rate swaps and foreign exchange forward contracts are valued using valuation techniques, which employ the use of markets observable data. The most frequently applied valuation techniques include forward pricing and swap models using present value calculations. The models incorporate various inputs including the credit quality of counterparties, foreign exchange spot and forward rates, yield curves of the respective currencies, interest rate curves and forward curves.

C.7.2. Fair value of financial instruments

The fair value of Millicom’s financial instruments are shown at amounts at which the instruments could be exchanged in a current transaction between willing parties, other than in a forced or liquidation sale. The fair value of all financial assets and all financial liabilities, except debt and financing approximate their carrying value largely due to the short-term maturities of these instruments. The fair values of all debt and financing have been estimated by the Group, based on discounted future cash flows at market interest rates.

C.7.3. Equity investments

As at December 31, 2024 and 2023, Millicom has no material investments in equity instruments.

C.7.4. Call and put options

Put Option - Tigo-UNE

On October 12, 2023, Millicom and its partner, Empresas Públicas de Medellin (EPM), agreed to recapitalize Tigo-UNE, Millicom's 50%-owned operation in Colombia. Each partner contributed COP 300 billion (approximately $74 million at the time of the transaction) to support the continued development of Tigo-UNE's strategy

F-60


Notes to the Consolidated Financial Statements For the years ended December 31, 2024, 2023 and 2022

With this agreement, both partners retain their current shareholding in Tigo-UNE. Furthermore they agreed to add in the shareholder's agreement an unconditional put option maturing on September 30, 2024, that, if exercised, would allow EPM to sell to Millicom their entire 50% stake in Tigo-UNE for COP 330 billion. As a result, a put option liability has been recognized in Millicom's statement of financial position, with its counterpart in the Group's equity. This put option expired as of September 30, 2024 as EPM did not exercise it. Consequently, the corresponding liability amounting to $79 million (after its foreign exchange revaluation) as of September 30, 2024 has been extinguished with its counterpart in the Group's equity.

D. Financial risk management

Exposure to interest rate, foreign currency, non-repatriation, liquidity, capital management and credit risks arise in the normal course of Millicom’s business. As part of the annual review of the above mentioned risks, the Group targets a strategy with respect to the use of derivatives and natural hedging instruments ranging from raising debt in local currency (where the Group targets to maintain 40% of debt in local currency) to maintaining at least a 75/25% mix between fixed and floating rate debt or agreeing to cover up to six months forward of operating costs and capex denominated in non-functional currencies through a rolling and layering strategy. Millicom’s financial risk management strategies may include the use of derivatives to the extent a market would exist in the jurisdictions where the Group operates. Millicom’s policy prohibits the use of such derivatives in the context of speculative trading.

Accounting policies for derivatives is further detailed in note C.7. On December 31, 2024 and 2023 fair value of derivatives held by the Group can be summarized as follows:


	2024	2023
	(US$ millions)
Derivatives
Cash flow hedge derivatives	(59)	(40)
Net derivative asset (liability)	(59)	(40)

D.1. Interest rate risk

Debt and financing issued at floating interest rates expose the Group to cash flow interest rate risk. Debt and financing issued at fixed rates expose the Group to fair value interest rate risk. The Group’s exposure to risk of changes in market interest rates relate to both of the above. To manage this risk, the Group’s policy is to maintain a combination of fixed and floating rate debt with a target that more than 75% of the debt be at fixed rate. The Group actively monitors borrowings against this target. The target mix between fixed and floating rate debt is reviewed periodically. The purpose of Millicom’s policy is to achieve an optimal balance between cost of funding and volatility of financial results, while considering market conditions as well as our overall business strategy. At December 31, 2024, approximately 84% of the Group’s borrowings are at a fixed rate of interest or for which variable rates have been swapped for fixed rates with interest rate swaps (2023: 80%).

A 100 basis point fall or rise in market interest rates for all currencies in which the Group had borrowings at December 31, 2024 would increase or reduce profit before tax from continuing operations for the year by approximately $9 million (2023: $14 million).

D.1.2. Currency and interest rate swap contracts

From time to time, Millicom enters into currency and interest rate swap contracts to manage its exposure to fluctuations in interest rates and currency fluctuations in accordance with its Group Treasury policy. Details of these arrangements are provided below.

MIC S.A. entered into a swap contract in order to hedge the foreign currency risk in relation to the 2027 SEC 2.2 billion senior unsecured sustainability bond (issued in January 2022, corresponding to $252.3 million, using the exchange rate at the time of the issuance of such bond - see note C.3.1.). This swap is accounted for as cash flow hedges as the timing and amounts of the cash flows under the swap agreement match the cash flows under the SEK bonds. Its maturity date is January 2027. The hedging relationship is highly effective and related fluctuations are recorded through other comprehensive income. At December 31, 2024, the fair values of the above swap amount to a liability of $59 million. (December 31, 2023: a liability of $46 million).

The Group's operation in Colombia also entered into several swap agreements in order to hedge foreign currency and interest rate risks on certain long-term debts. These swaps are accounted for as cash flow hedges and related fair value changes are recorded through other comprehensive income. All swap contracts attached to the 2020 Syndicated loan agreement were terminated in December, 2024, after the repayment of the outstanding amount of the Syndicated loan and were settled against a cash collection of $9 million. The fair value of Colombia swaps amounted to nil as of December 31, 2024 (December 31, 2023: an asset of $6 million).

In January 2023, MIC S.A. also entered into two currency swap agreements to hedge an intercompany receivable of COP 206 billion (approximately $41 million) owed by UNE (refer to note C.3.1.).

As a summary, the net fair value of the derivative financial instruments for the Group, as of December 31, 2024 amounted to a liability of $59 million (December 31, 2023: a liability of $40 million ).

Interest rate and currency swaps are measured with reference to Level 2 of the fair value hierarchy.There are no other derivative financial instruments with a significant fair value at December 31, 2024.

D.2. Foreign currency risks

The Group is exposed to foreign exchange risk arising from various currency exposures in the countries in which it operates. Foreign exchange risk arises from future commercial transactions, recognized assets and liabilities and net investments in foreign operations.

Millicom seeks to reduce its foreign currency exposure through a policy of matching, as far as possible, assets and liabilities denominated in foreign currencies, or entering into agreements that limit the risk of exposure to currency fluctuations against the US dollar reporting currency. In some cases, Millicom may also borrow in US dollars where it is either commercially more advantageous for joint ventures and subsidiaries to incur debt obligations in US dollars or where US dollar denominated borrowing is the only funding source available to a joint venture or subsidiary. In these circumstances, Millicom accepts the remaining currency risk associated with financing its joint ventures and subsidiaries, principally because of the relatively high cost of forward cover, when available, in the currencies in which the Group operates.

D.2.1. Debt denominated in US dollars and other currencies

Debt denomination at December 31


	2024	2023
	(US$ millions)
Debt denominated in US dollars	3,429	3,859
Debt denominated in currencies of the following countries:
Guatemala	496	640
Colombia	554	694
Bolivia	153	246
Paraguay	233	158
El Salvador(i)	71	174
Panama(i)	734	759
Luxembourg (COP denominated)	33	38
Costa Rica	113	110

Total debt denominated in other currencies	2,386	2,819
Total debt (ii)	5,815	6,678

(i) El Salvador's official unit of currency is the U.S. dollar, while Panama uses the U.S. dollar as legal tender. The Group's local debt in both countries is therefore denominated in U.S. dollars but presented as local currency (LCY).

(ii) Excluding vendor financing of $18 million in Colombia, due within one year, as of December 31, 2023.

At December 31, 2024, if the US dollar had weakened/strengthened by 10% against the other functional currencies of our operations and all other variables held constant, then profit before tax from continuing operations would have increased/decreased by $8 million (2023: $25 million). This increase/decrease in profit before tax would have mainly been as a result of the conversion of the USD-denominated net debts in our operations with functional currencies other than the US dollar.

D.3. Non-repatriation risk

Millicom’s operating subsidiaries and joint ventures generate most of the revenue of the Group and in the currency of the countries in which they operate. Millicom is therefore dependent on the ability of its subsidiaries and joint venture operations to transfer funds to the Company.

Although foreign exchange controls exist in some of the countries in which Millicom Group companies operate, none of these controls currently significantly restrict the ability of these operations to pay interest, dividends, technical service fees, royalties or repay loans by exporting cash, instruments of credit or securities in foreign currencies. However, existing foreign exchange controls may be strengthened in countries where the Group operates, or foreign exchange controls may be introduced in countries where the Group operates that do not currently impose such restrictions. If such events were to occur, the Company’s ability to receive funds from the operations could be subsequently restricted, which would impact the Company’s ability to make payments on its interest and loans and, or pay dividends to its shareholders. As a policy, all operations which do not face restrictions to deposit funds offshore and in hard currencies should do so for the surplus cash generated on a weekly basis. The Company and its subsidiaries make use of physical cash pooling arrangements in hard currencies to the extent permitted.

In addition, in some countries it may be difficult to convert large amounts of local currency into foreign currency because of limited foreign exchange markets. The practical effects of this may be time delays in accumulating significant amounts of foreign currency and exchange risk, which could have an adverse effect on the Group. This is a relatively rare case for the countries in which the Group operates.

Lastly, repatriation most often results in taxation, which is evidenced in the amount of taxes paid by the Group relative to the Corporate Income Tax reported in its statement of income.

D.4. Credit and counterparty risk

Financial instruments that subject the Group to credit and counterparty risk include cash and cash equivalents, pledged deposits, letters of credit, trade receivables, amounts due from joint venture partners and associates, vendor financing and other current assets and derivatives. Counterparties to agreements relating to the Group’s cash and cash equivalents, pledged deposits and letters of credit are financial institutions generally with investment grade ratings. Management does not believe there are significant risks of non-performance by these counterparties and maintain a diversified portfolio of banking partners. Allocation of deposits across banks are managed such that the Group’s counterparty risk with a given bank stays within limits which have been set, based on each bank’s credit rating.

F-63


Notes to the Consolidated Financial Statements For the years ended December 31, 2024, 2023 and 2022

A large portion of revenue of the Group is comprised of prepaid products and services. For postpaid customers, the Group follows risk control procedures to assess the credit quality of the customer, taking into account its financial position, past experience and other factors. Accounts receivable also comprise balances due from other telecom operators. Credit risk of other telecom operators is limited due to the regulatory nature of the telecom industry, in which licenses are normally only issued to credit-worthy companies. The Group maintains a provision for expected credit losses of trade receivables based on its historical credit loss experience.

As the Group has a large number of internationally dispersed customers, there is generally no significant concentration of credit risk with respect to trade receivables, except for certain B2B customers (mainly governments). See note F.1.

D.5. Liquidity risk

Liquidity risk is the risk that an entity will encounter difficulty in meeting obligations associated with financial liabilities. The Group has significant indebtedness but also has significant cash balances. Millicom evaluates its ability to meet its obligations on an ongoing basis using a recurring liquidity planning tool. This tool considers the operating net cash flows generated from its operations and the future cash needs for borrowing, interest payments, dividend payments and capital and operating expenditures required in maintaining and developing its operating businesses.

The Group manages its liquidity risk through the use of bank loans, bonds, vendor financing, Export Credit Agencies and Development Finance Institutions (DFI) loans. Millicom believes that there is sufficient liquidity available in the markets to meet ongoing liquidity needs. Additionally, Millicom is able to arrange offshore funding. Millicom has a diversified financing portfolio with commercial banks representing about 20% of its gross financing (2023: 24%), with bonds representing 66% (2023: 61%) and leases representing 14% (2023: 13%).

D.6. Capital management

The primary objective of the Group’s capital management is to ensure a strong credit rating and solid capital ratios in order to support its business and maximize shareholder value.

The Group manages its capital structure with reference to local economic conditions and imposed restrictions such as debt covenants (see section C.3.5.). To maintain or adjust its capital structure, the Group may make dividend payments to shareholders, return capital to shareholders through share repurchases or issue new shares. At December 31, 2024, Millicom was rated at one notch below investment grade by the independent rating agencies Moody’s (Ba1) and Fitch (BB). On February 6, 2024, Moody’s downgraded Millicom by one notch to ba2 (with a stable outlook +) basically based on quantitative metrics being below ranges than ba1 rating scale ranges. The Group primarily monitors capital (with our covenants primarily) based on net debt to EBITDAaL.

Gearing ratio

The Group reviews its gearing ratio (net debt divided by total capital plus net debt) periodically. Capital represents equity attributable to the equity holders of the parent.


	Note	2024	2023
	(US$ millions)
Net debt	C.6.	5,174	5,956
Equity attributable to Owners of the Company	C.1.	3,628	3,529
Net debt and equity		8,802	9,485
Gearing ratio		0.59	0.63

E. Long-term assets

E.1. Intangible assets

Millicom’s intangible assets mainly consist of goodwill and customer lists arising from acquisitions, licenses and spectrum.

E.1.1. Accounting for intangible assets

Intangible assets acquired in business acquisitions are initially measured at fair value at the date of acquisition. Those which are acquired separately are measured at cost. Internally generated intangible assets, excluding capitalized development costs, are not

F-65


Notes to the Consolidated Financial Statements For the years ended December 31, 2024, 2023 and 2022

capitalized but expensed to the statement of income in the expense category consistent with the function of the intangible assets. Subsequently intangible assets are carried at cost, less any accumulated amortization and any accumulated impairment losses.

Intangible assets with finite useful lives are amortized over their estimated useful lives using the straight-line method and assessed for impairment whenever there is an indication that the intangible asset may be impaired. The amortization period and the amortization method for intangible assets with finite useful lives are reviewed at least at each financial year end. Changes in expected useful lives or the expected beneficial use of the assets are accounted for by changing the amortization period or method, as appropriate, and treated as changes in accounting estimates.

Amortization expense on intangible assets with finite lives is recognized in the consolidated statement of income in the expense category consistent with the function of the intangible assets.

Goodwill

Goodwill represents the excess of cost of an acquisition over the Group’s share in the fair value of identifiable assets less liabilities and contingent liabilities of the acquired subsidiary, at the date of the acquisition. If the fair value or the cost of the acquisition can only be determined provisionally, then goodwill is initially accounted for using provisional values. Within 12 months of the acquisition date, any adjustments to the provisional values are recognized. This is done when the fair values and the cost of the acquisition have been finally determined. Adjustments to provisional fair values are made as if the adjusted fair values had been recognized from the acquisition date. Following initial recognition, goodwill is measured at cost, less any accumulated impairment losses. Gains or losses on the disposal of an entity include the carrying amount of goodwill relating to the entity sold.

Where goodwill forms part of a cash-generating unit (or group of cash-generating units) and part of the operation within that unit is disposed of, the goodwill associated with the operation disposed of is included in the carrying amount of the operation when determining the gain or loss on disposal. Goodwill disposed of in this manner is measured, based on the relative values of the operation disposed and the portion of the cash-generating unit retained.

Goodwill on acquisition of joint ventures or associates is included in investments in joint ventures and associates.

Licenses and Spectrum

Licenses and spectrum are recorded at either historical cost or, if acquired in a business combination, at fair value at the date of acquisition. Cost includes cost of acquisition and other costs directly related to acquisition and retention of licenses over the license period. These costs may include up-front and deferred payments as well as estimates related to fulfillment of terms and conditions related to the licenses such as service or coverage obligations, especially when there is a clear objective evidence that the cost of fulfilling these obligations will be significantly onerous for the Group.

Licenses and spectrum have a finite useful life and are carried at cost less accumulated amortization and any accumulated impairment losses. Licenses and spectrum are amortized from the date the network is available for use on a straight-line basis over the license period. Amortization is calculated using the straight-line method to allocate the cost of the licenses over their estimated useful lives. The terms of licenses, which have been awarded for various periods, are subject to periodic review for, among other things, rate setting, frequency allocation and technical standards. Licenses held, subject to certain conditions, are usually renewable and generally non-exclusive. When estimating useful lives of licenses, renewal periods are included only if there is evidence to support renewal by the Group without significant cost.

Trademarks and customer lists

Trademarks and customer lists are recognized as intangible assets only when acquired or gained in a business combination. Their cost represents fair value at the date of acquisition. Trademarks have indefinite or finite useful lives and customers lists have finite useful lives. Main factors considered in the determination of the indefinite useful lives include the years that they have been and are expected to be in service and their recognition among peers in the industry. Trademarks and customer lists used by the Group for its own activities are unlikely to generate largely independent cash inflows and therefore are tested for impairment annually together with other assets at each cash-generating unit level. Finite useful life trademarks are carried at cost, less accumulated amortization and any accumulated impairment losses. Amortization is calculated using the straight-line method to allocate the cost of the trademarks and customer lists over their estimated useful lives. The estimated useful lives for trademarks and customer lists are based on specific characteristics of the market in which they exist.

Estimated useful lives are:


			Years
Estimated useful lives
Trademarks			1 to 15
Customer lists			4 to 20

Programming and content rights

Programming and content master rights which are purchased or acquired in business combinations which meet certain criteria are recorded at cost as intangible assets. The rights must be exclusive, related to specific assets which are sufficiently developed, and probable to bring future economic benefits and have validity for more than one year. Cost includes consideration paid or payable and other costs directly related to the acquisition of the rights, and are recognized at the earlier of payment or commencement of the broadcasting period to which the rights relate.

F-66


Notes to the Consolidated Financial Statements For the years ended December 31, 2024, 2023 and 2022

Programming and content rights capitalized as intangible assets have a finite useful life and are carried at cost, less accumulated amortization and any accumulated impairment losses. Amortization is calculated using the straight-line method to allocate the cost of the rights over their estimated useful lives.

Non-exclusive and programming and content rights for periods less than one year are expensed over the period of the rights.

Indefeasible rights of use

There is no universally-accepted definition of an indefeasible rights of use (IRU). These agreements come in many forms. However, the key characteristics of a typical arrangement include:

• The right to use specified network infrastructure or capacity;

• For a specified term (often the majority of the useful life of the relevant assets);

• Legal title is not transferred;

• A number of associated service agreements including operations and maintenance (O&M) and co-location agreements. These are typically for the same term as the IRU; and

• Any payments are usually made in advance.

IRUs are accounted for either as a lease, or service contract based on the substance of the underlying agreement.

IRU arrangements will qualify as a lease if, and when:

• The purchaser has an exclusive right for a specified period; and

• The capacity is physically limited and defined; and

• The purchaser bears all costs related to the capacity (directly or not) including costs of operation, administration and maintenance; and

• The purchaser bears the risk of obsolescence during the contract term.

If all of these criteria are not met, the IRU is treated as a service contract.

An IRU of network infrastructure (cables or fiber) is accounted for as a right of use asset (see E.3.), while capacity IRU (wavelength) is accounted for as an intangible asset.

The costs of an IRU recognized as service contract is recognized as prepayment and amortized in the statement of income as incurred over the duration of the contract.

E.1.2. Impairment of non-financial assets

At each reporting date Millicom assesses whether there is an indication that a non-financial asset may be impaired. If any such indication exists, or when annual impairment testing for a non-financial asset is required, an estimate of the asset’s recoverable amount is made. The recoverable amount is determined based on the higher of its fair value less cost to sell, and its value in use, for individual assets, unless the asset does not generate cash inflows that are largely independent of those from other assets or groups of assets.

Where the carrying amount of an asset exceeds its recoverable amount, the asset is considered impaired and is written down to its recoverable amount. Where no comparable market information is available, the fair value, less cost to sell, is determined based on the estimated future cash flows discounted to their present value using a discount rate that reflects current market conditions for the time value of money and risks specific to the asset. The foregoing analysis also evaluates the appropriateness of the expected useful lives of the assets. Impairment losses related to assets of continuing operations are recognized in the consolidated statement of income in expense categories consistent with the function of the impaired asset.

At each reporting date an assessment is made as to whether there is any indication that previously recognized impairment losses may no longer exist or may have decreased. If such indication exists, the recoverable amount is estimated. Other than for goodwill, a previously recognized impairment loss is reversed if there has been a change in the estimate used to determine the asset’s recoverable amount since the last impairment loss was recognized. If so, the carrying amount of the asset is increased and cannot exceed the carrying amount that would have been determined, net of depreciation, had no impairment loss been recognized for the asset in prior years. Such reversal is recognized in profit or loss. After such a reversal, the depreciation charge is adjusted in future periods to allocate the asset’s revised carrying amount, less any residual value, on a systematic basis over its remaining useful life.

E.1.6. Impairment testing of goodwill and indefinite useful life trademarks

Goodwill and indefinite useful life trademarks from CGUs are tested for impairment at least once a year and more frequently if events or changes in circumstances indicate that the carrying value may be impaired. Impairment losses on goodwill are not reversed.

Goodwill arising on business combinations is allocated to each of the Group’s CGUs or groups of CGUs that are expected to benefit from the synergies of the combination, irrespective of whether other assets or liabilities of the Group are assigned to those units or groups of units. Each unit or group of units to which the goodwill is allocated:

• Represents the lowest level within the Group at which the goodwill is monitored for internal management purposes; and

• Is not larger than an operating segment.

Impairment is determined by assessing the value-in-use and, if appropriate, the fair value less costs to sell of the CGU (or group of CGUs), to which goodwill relates.

Impairment testing at December 31, 2024 and at December 31, 2023

Goodwill and indefinite useful life trademarks were tested for impairment by assessing the recoverable amount against the carrying amount of the CGU based on discounted cash flows. The recoverable amounts are based on value-in-use. The value-in-use is determined based on the method of discounted cash flows. The cash flow projections used (operating profit margins, income tax, working capital, capex and license renewal cost) are extracted from business plans approved by management, covering a ten-year planning horizon.

F-69


Notes to the Consolidated Financial Statements For the years ended December 31, 2024, 2023 and 2022

The Group uses a ten-year planning horizon to obtain a stable business outlook, in particular due to the long investment cycles in the industry and the long-term planned and expected investments in licenses and spectrum, with expenditures extending beyond 10 years. Moreover, we operate in emerging markets where telecom operators still have significant opportunities for continued penetration and growth. Our markets are mostly consolidated, with two or three players per market, therefore, using ten-year projections reduces the emphasis on terminal values.

Additionally, the Group has performed a sensitivity analysis to assess the potential impact on carrying values when using a five-year plan instead. The results of this analysis indicate that applying perpetuity growth rates at the end of an initial five-year plan does not result in any impairment. Furthermore, it does not reduce the recoverable value by more than 5% in any CGU as compared to the recoverable amount derived from the ten-year plan.

Cash flows beyond this period are extrapolated using a perpetual growth rate. Management validates the reasonableness of the results of the test by comparing the share price implied by the 'sum of the parts' with the market share price. Any gap is reviewed, analyzed and documented. When value-in-use results are lower than the carrying values of the CGUs, management determines the recoverable amount by using the fair value less cost of disposal (FVLCD) of the CGUs. FVLCD is usually determined by using recent offers received from third parties (Level 1).

For the years ended December 31, 2024 and 2023, management concluded that no impairment should be recorded in the Group consolidated financial statements.

Key assumptions used in value in use calculations

The process of preparing the cash flow projections considers the current market condition of each CGU, analyzing the macroeconomic, competitive, regulatory and technological environments, as well as the growth opportunities of the CGUs. Therefore, a growth target is defined for each CGU, based on the appropriate allocation of operating resources and the capital investments required to achieve the target. The foregoing forecasts could differ from the results obtained through time; however, the Group prepares its estimates based on the current situation of each of the CGUs. Relevance of budgets used for the impairment test is also reviewed annually, with management performing regressive analysis between actual figures and budget/Long Range Plans (LRPs) used for previous year impairment test.

The cash flow projections for all CGUs is most sensitive to the following key assumptions:

•EBITDA margin is determined by dividing EBITDA by total revenues.

•CAPEX intensity is determined by dividing CAPEX by total revenues.

•Perpetual growth rate does not exceed the countries' GDP.

•Weighted average cost of capital (“WACC”) is used to discount the projected cash flows.

The most significant estimates used for the 2024 and 2023 impairment test are shown below:


CGU	Average EBITDA margin (%) (i)		Average CAPEX intensity (%) (i)		Perpetual growth rate (%)		WACC rate after tax (%) (ii)
	2024	2023	2024	2023	2024	2023	2024	2023
Bolivia	46.9	41.3	14.8	13.6	1.0	1.0	22.9	15.4
Colombia	41.4	39.6	11.2	12.3	2.0	2.0	8.9	10.7

Paraguay	50.8	46.8	12.9	14.5	—	1.0	8.6	9.8

(i) Average is computed over the period covered by the plan.

(ii) Millicom uses post-tax rate for the impairment-test, the difference with the pre-tax not resulting in different conclusions.

Sensitivity analysis to changes in assumptions

Management performed a sensitivity analysis on key assumptions within the test. The following maximum increases or decreases, expressed in percentage points, were considered for all CGUs:

At December 31, 2024 and at December 31, 2023, the sensitivity analysis shows no impairment under the above mentioned changes in assumptions for all CGUs, except for Nicaragua. If the assumptions used in the impairment test were changed to a greater extent than as presented in the following table, the changes would, in isolation, trigger a potential impairment loss being recognised for the Nicaragua CGU in the years ended December 31, 2024 and December 31, 2023 .

E.2. Property, plant and equipment

E.2.1. Accounting for property, plant and equipment

Items of property, plant and equipment are stated at historical cost less accumulated depreciation and accumulated impairment. Historical cost includes expenditure that is directly attributable to acquisition of items. The carrying amount of replaced parts is derecognized.

Depreciation is calculated using the straight-line method over the shorter of the estimated useful life of the asset and the remaining life of the license associated with the assets, unless the renewal of the license is contractually possible.

The assets’ residual value and useful life is reviewed, and adjusted if appropriate, at each statement of financial position date.

As explained in the Introduction note, during 2024, we revised the estimated useful lives of our fiber optic network assets and related equipment/software. As a result, the estimated useful lives of the Group's Fiber Optic Network useful life were changed from 15 years to 25 years while the related equipment/Software useful life range was increased to 5-10 years (previously 5-7 years for equipment and 5 years for software). Additionally, during 2023, the estimated useful lives of some property, plant and equipment were revised. As a result, the estimated useful lives of the Group's towers, poles and ducts were changed from 15 to 25 years, while the related civil works' useful lives were increased from 10 to 15 years. Refer to the Introduction - Estimates note for further details.


Estimated useful lives			Duration
Buildings			Up to 40 years
Networks (including civil works)			5 to 25 years
Other			2 to 10 years

The carrying values of property, plant and equipment are reviewed for impairment when events or changes in circumstances indicate that the carrying value may not be recoverable. An asset’s carrying amount is written down immediately to its recoverable amount if its carrying amount is greater than its estimated recoverable amount.

F-71


Notes to the Consolidated Financial Statements For the years ended December 31, 2024, 2023 and 2022

Construction in progress consists of the cost of assets, labor and other direct costs associated with property, plant and equipment being constructed by the Group, or purchased assets which have yet to be deployed. When the assets become operational, the related costs are transferred from construction in progress to the appropriate asset category and depreciation commences.

Subsequent costs are included in the asset’s carrying amount or recognized as a separate asset, as appropriate, when it is probable that future economic benefits associated with the item will flow to the Group and the cost of the item can be measured reliably. Ongoing routine repairs and maintenance are charged to the statement of income in the financial period in which they are incurred.

Costs of major inspections and overhauls are added to the carrying value of property, plant and equipment and the carrying amount of previous major inspections and overhauls is derecognised.

Equipment installed on customer premises which is not sold to customers is capitalized and amortized over the customer contract period.

A liability for the present value of the cost to remove an asset on both owned and leased sites (for example cell towers) and for assets installed on customer premises (for example set-top boxes), is recognized when a present obligation for the removal exists. The corresponding cost of the obligation is included in the cost of the asset and depreciated over the useful life of the asset, or lease period if shorter.

Borrowing costs that are directly attributable to the acquisition or construction of a qualifying asset are capitalized as part of the cost of that asset when it is probable that such costs will contribute to future economic benefits for the Group and the costs can be measured reliably.

Assets held for sale - Towers sales in Colombia

On January 24, 2024, Colombia Movil S.A. ESP (“Tigo Colombia”) signed an agreement to sell and lease back, under a long-term lease agreement, 1,132 telecommunication towers to Towernex Colombia S.A.S. (“Towernex”), a KKR company. The total sale consideration amounts to $77 million, out of which $26 million will be received in subsequent years. Under IFRS 16, this transaction is considered a sale and leaseback.

The transfer of the towers to Towernex consists of three batches, out of which two already completed:

▪First batch (occurred on March 14, 2024): 759 towers were sold, generating net cash proceeds of $38 million, net of transaction costs and a $13 million receivable , for Tigo Colombia. The company also recorded lease obligations and a financing component totaling $48 million related to the towers sold and leased back.

▪Second batch (occurred on September 4, 2024): 250 towers were sold, generating net cash proceeds of $13 million, net of transaction costs and a $4 million receivable, for Tigo Colombia. The company also recorded lease obligations and a financing component totaling $16 million related to the towers sold and leased back.

▪Third batch (expected in first quarter of the financial year 2025): The remaining 123 towers are intended to be sold. In accordance with IFRS 5, these towers remain classified as assets held for sale and their depreciation has stopped.

Assets held for sale / Disposal Group - Mobile Network sharing agreement in Colombia

On February 26, 2024, Tigo Colombia and Telecomunicaciones S.A. ESP BIC (“ColTel”) signed an agreement to share their mobile networks. This collaboration involves two new joint arrangements. (both qualifying as joint operations, as defined in IFRS 11):

▪A 'NetCo ("UNIRED")': This company holds and manages the radio access network (RAN) infrastructure as well as the site lease agreements. Each operator owns 50% of this NetCo.

Transfers of RAN assets to UNIRED happened in December 2024, when UNIRED did a step-up exercise to determine the fair values of the contributions from both joint operators. The portion of this step-up exercise attributable to ColtTel has been booked as "Other operating Income" ($28 million, together with a gain of $3 million related to the equalization of Tigo Colombia and Coltel in UNIRED. The transfer of lease agreements is taking place as from January 2025 and as of December 31, 2024 met the criteria of IFRS 5: "Non-current Assets Held for Sale and Discontinued Operations" criteria.

F-75


Notes to the Consolidated Financial Statements For the years ended December 31, 2024, 2023 and 2022

▪A 'Unión Temporal' ("UT"): This temporary joint arrangement will manage the spectrum licenses and related liabilities. Similarly, ownership is split 50/50 between the two operators. In December 2024, Tigo Colombia got the approval to transfer to the UT the first block of spectrum (as defined by resolution 332 of the 700MwZ Spectrum from the Ministry of Information Technologies and Communications, "Mintic"). Consequently, the assets and liabilities related to such resolution were derecognized in Tigo Colombia with the subsequent recognition of Tigo's Colombia 50% share in the UT.

In accordance with IFRS 5, certain assets and related liabilities are kept as of December 31, 2024 as "held for sale": Lease agreements. and Spectrum licenses and related liabilities not yet transferred (that will be managed by the Union Temporal)

Asset held for sale - Towers sales in Nicaragua

As part of the other assets portfolio sell within the 'sale of Lati International S.A and other assets to SBA' agreement dated on October 28, 2024 and further detailed in Note 3 above, Millicom Nicaragua expects to sell approximately 400 towers under a sale-and-leaseback model and also expects to transfer the related ground leases (Right of Use and Lease Liabilities). Management believes that the criteria set out under IFRS 5 "Non-current Assets Held for Sale and Discontinued Operations" are met for the fixed assets, right-of-use assets and lease liabilities related to the sites within the scope of the sale to SBA. Consequently, as of December 31, 2024 those assets and liabilities of our operations in Nicaragua were classified as held for sale See note H..

F. Other assets and liabilities

F.1. Trade receivables

Millicom’s trade receivables mainly comprise interconnect receivables from other operators, postpaid mobile and residential cable subscribers, as well as B2B customers. The nominal value of receivables adjusted for impairment approximates the fair value of trade receivables.

Others	37	7	8	52
Total	319	61	63	443

Trade receivables are initially recognized at fair value and subsequently measured at amortized cost using the effective interest method, less provision for expected credit losses. The Group recognizes an allowance for expected credit losses (ECLs) applying a simplified approach in calculating the ECLs. Therefore, the Group does not track changes in credit risk, but instead recognizes a loss allowance based on lifetime of ECLs at each reporting date. The Group has established a provision matrix that is based on its historical credit loss experience, adjusted for forward-looking factors specific to the debtors and the economic environment. The provision for expected credit losses is recognized in the consolidated statement of income within 'Equipment, programming and other direct costs'.

F.2. Inventories

Inventories are stated at the lower of cost and net realizable value. Cost is determined using the first-in, first-out method. Net realizable value is the estimated selling price in the ordinary course of business, less applicable variable selling expenses.

F.3. Trade payables

Trade payables are initially recognized at fair value and subsequently measured at amortized cost using the effective interest method where the effect of the passage of time is material.

From time to time, the Group enters into agreements to extend payment terms with various suppliers, and with factoring companies when such payments are discounted. Specifically, in March 2022, Millicom started to implement a supplier financing program with Citibank that as of December 31, 2024 covers five countries (El Salvador, Honduras, Nicaragua, Panama and Paraguay). In this program, Millicom designates Citibank as its paying agent, allowing participating suppliers – who enter into a separate agreement with Citibank – to transfer the rights of the approved invoices to Citibank. Millicom pays to Citibank at the invoices' due date, under the same terms and conditions that were originally agreed with the suppliers. The liabilities related to the invoices included in the program remain classified as trade payables. As of December 31, 2024, the outstanding balance of invoices transferred from suppliers to Citibank is $29 million (2023: $26 million).

F.4. Current and non-current provisions and other liabilities

Provisions are recognized when the Group has a present obligation (legal or constructive) as a result of a past event, if it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation and a reliable estimate can be made of the amount of the obligation. Where the Group expects some or all of a provision to be reimbursed, for example under an insurance contract, the reimbursement is recognized as a separate asset, but only when the reimbursement is virtually certain.

The expense relating to any provision is presented in the statement of income net of any reimbursement. If the effect of the time value of money is material, provisions are discounted using a current pre-tax rate that reflects, where appropriate, risks specific to the liability. Where discounting is used, increases in the provision due to the passage of time are recognized as interest expenses.

F.4.3. Non-current payables and accruals for capital expenditure

Non-current payables and accruals for capital expenditure include an amount of $140 million (December 31, 2023: $846 million) in relation to spectrum and license payables in Colombia. The major part of this payable is related to:

1) the acquisition, in December 2019, of licenses granting the right to use a total of 40 MHz in the 700 MHz band in Colombia. This 20-year license will expire in 2040. During the same auction, Tigo Colombia also acquired 55 MHz in the 1900 band and 30 MHz of AWS. Tigo Colombia agreed to a total notional consideration of COP 2.45 billion (equivalent to approximately $615 million at initial date's exchange rate), of which approximately 55% is payable in cash and 45% in coverage obligations to be met by 2025.

An initial payment of approximately $33 million was made in 2020, with the remainder payable in 12 annual installments beginning in 2026 and ending in 2037. The 55% cash portion bears interest at a rate corresponding to the Government Títulos de Tesorería (TES). In April and May 2020, local management received permission to operate 40 Mhz in the 700 MHz band and accounted for the spectrum as an intangible asset at an amount of $388 million corresponding to the net present value of the future payments, plus other costs directly attributable to this acquisition.

As of December 31, 2024, the outstanding payable in relation to these licenses classified as Liabilities Held for Sale amount to $456 million (December 31, 2023: $467 million, classified as non-current payable and accruals for capital expenditure). The related future interest commitments will be recognized in the joint operation as interest expense over the next 17 years. The remaining 45% consideration due as coverage obligations are currently being estimated and will be recognized in the statement of financial position of the joint operation as incurred.

2) in February 2023, the renewal of the spectrum license related to 1900 Mhz band for an additional period of 20 years. The total consideration amounts to COP 1.14 billion (approximately $281 million at initial date's exchange rate). The first payment representing 20% of the total consideration occurred on October 27, 2023.

Notes to the Consolidated Financial Statements For the years ended December 31, 2024, 2023 and 2022

As of December 31, 2024, the outstanding payable in relation to these licenses classified as Liabilities Held for Sale amount to $239 million, classified as non-current payable and accruals for capital expenditure. The remaining consideration will be paid from the joint operation in annual installments over the next 20 years and bears interest at the moving average of the last 24 months consumer price index (CPI) rate.

The transaction price allocated to the remaining performance obligations (unsatisfied or partially unsatisfied) as at December 31, 2024 is $90 million ($89 million is expected to be recognized as revenue in the 2025 financial year and the remaining $2 million in the 2026 financial year or later). This amount does not consider contracts that have an original expected duration of one year or less, neither contracts in which consideration from a customer corresponds to the value of the entity’s performance obligation to the customer (i.e. billing corresponds to accounting revenue).

G.2. Capital and operational commitments

Millicom has a number of capital and operational commitments to suppliers and service providers in the normal course of its business. These commitments are mainly contracts for acquiring network and other equipment, and leases for towers and other operational equipment.

G.2.1. Capital commitments

At December 31, 2024, the Group had fixed commitments to purchase network equipment, other fixed assets and intangible assets of $285 million of which $215 million are due within one year (December 31, 2023: $350 million of which $254 million were due within one year). The Group’s share of commitments in the Honduras joint venture is $19 million, of which $19 million are due within one year (December 31, 2023: $18 million, all of which were due within one year). Additionally, the Group's share of commitments in the UNIRED joint operation (see note A.2.2.) is $6 million.

G.3. Contingent liabilities

G.3.1. Litigation and legal risks

The Group is contingently liable with respect to lawsuits, legal, regulatory, commercial and other legal risks that arise in the normal course of business. As of December 31, 2024, the total amount of claims brought against the Company and its subsidiaries is $209 million, after the updates on the Costa Rica case described below and the final settlement case reached for our former operation in Tanzania, as mentioned in Note A.1.3. (December 31, 2023: $328 million). The Group's share of the comparable exposure for its joint venture in Honduras is $8 million (December 31, 2023: $9 million).

As at December 31, 2024, $104 million has been provisioned by its subsidiaries for these risks in the consolidated statement of financial position, including the Costa Rica case described in the below paragraph (December 31, 2023: $14 million). The Group’s share of provisions made by the joint venture in Honduras was $1 million (December 31, 2023: $1 million). While it is not possible to ascertain the ultimate legal and financial liability with respect to these claims and risks, the ultimate outcome is not anticipated to have a material effect on the Group’s financial position and results of operations.

On February 13, 2024, the New York Supreme Court granted summary judgment in favor of a breach of contract claim filed by Telefónica after Millicom terminated the acquisition of Telefónica's Costa Rican business in 2020. The Court also ruled in favor of Telefónica's methodology for calculating prejudgment interest. On December 17, 2024, the First Department of the New York Appellate Division upheld the trial court's ruling against Millicom regarding breach of contract but reversed the trial court's ruling regarding the calculation of damages and adopted Millicom's methodology for calculation. As a result, in December 2024, Millicom recorded a legal provision of approximately $88 million impacting the Non-Operating Expenses, net line in the Statement of Income for the year ended December 31, 2024.

In April 2022, we received a subpoena from the DOJ requesting information concerning our business in Guatemala (“Tigo Guatemala”), including information related to the purchase in 2021 of our former joint venture partner’s interest in Tigo Guatemala and information related to any contacts with certain Guatemalan government officials. The subpoena also requested information concerning our operations in other countries in Latin America. In May 2023, we received a second subpoena from the DOJ requesting additional information regarding Tigo Guatemala. We are cooperating with the DOJ. At this time, we cannot predict the ultimate scope, timing or outcome of this matter.

Other

At December 31, 2024, Millicom has various other less significant claims which are not disclosed separately in these consolidated financial statements because they are either not material or the related risk is remote.

G.3.2. Tax related risks and uncertain tax position

The Group operates in developing countries where the tax systems, regulations and enforcement processes have varying stages of development creating uncertainty regarding the application of the tax law and interpretation of tax treatments. The Group is also subject to regular tax audits in the countries where it operates. When there is uncertainty over whether the taxation authority will accept a specific tax treatment under the local tax law, that tax treatment is therefore uncertain. The resolution of tax positions taken by the Group, through negotiations with relevant tax authorities or through litigation, can take several years to complete and, in some cases, it is difficult to predict the ultimate outcome. Therefore, judgment is required to determine liabilities for taxes.

In assessing whether and how an uncertain tax treatment affects the determination of taxable profit (tax loss), tax bases, unused tax losses, unused tax credits and tax rates, the Group assumes that a taxation authority with the right to examine amounts reported to it will examine those amounts and have full knowledge of all relevant information when making those examinations.

The Group has a process in place, and applies significant judgment, in identifying uncertainties over income tax treatments. Management considers whether or not it is probable that a taxation authority will accept an uncertain tax treatment. On that basis, the identified risks are split into three categories (i) remote risks (risk of outflow of tax payments are up to 5%), (ii) possible risks (risk of outflow of tax payments assessed from 5% to 50%) and probable risks (risk of outflow is more than 50%). The process is repeated every quarter by the Group.

If the Group concludes that it is probable or certain that the taxation authority will accept the tax treatment, the risks are categorized either as possible or remote, and it determines the taxable profit (tax loss), tax bases, unused tax losses, unused tax credits or tax rates consistently with the tax treatment used or planned to be used in its income tax filings. The risks considered as possible are not provisioned but disclosed as tax contingencies in the Group consolidated financial statements while remote risks are neither provisioned nor disclosed.

If the Group concludes that it is probable that the taxation authority will not accept the Group’s interpretation of the uncertain tax treatment, the risks are categorized as probable, and are presented to reflect the effect of uncertainty in determining the related taxable profit (tax loss), tax bases, unused tax losses, unused tax credits or tax rates by generally using the most likely amount method – the single most likely amount in a range of possible outcomes.

If an uncertain tax treatment affects both deferred tax and current tax, the Group makes consistent estimates and judgments for both. For example, an uncertain tax treatment may affect both taxable profits used to determine the current tax and tax bases used to determine deferred tax.

If facts and circumstances change, the Group reassesses the judgments and estimates regarding the uncertain tax position taken.

At December 31, 2024, the tax risks exposure of the Group's subsidiaries is estimated at $304 million, for which provisions of $54 million have been recorded in tax liabilities; representing management's assessment of the probable cash outflow of eventual claims and required payments related to those risks (December 31, 2023: $279 million of which provisions of $52 million were recorded). The Group's share of comparable tax exposure and provisions in its joint venture amounts to $134 million (December 31, 2023: $118 million) and $8 million (December 31, 2023: $7 million), respectively.
