MANAGEMENT COMMENTS

During this quarter, we continued to see a solid recovery in cement sales volume, which grew by 7.1%, driven primarily by increased demand for bagged cement and concrete used in infrastructure-related projects. Gross profit rose by 11.2%, reflecting our ongoing efforts to improve cost efficiencies and strengthen profitability. Although operating expenses were higher—mainly due to the one-time first-year bonus included in our recent three-year collective bargaining agreement—we achieved consolidated EBITDA of S/ 130.2 million, representing a 9.0% increase year-over-year.

Despite three decades of sustained economic growth, Peru still faces a significant infrastructure and housing gap. As a leading provider of building solutions, we are deeply aware of our role in addressing this challenge. By delivering high-quality products and services, and staying very close to our clients to attend to their particular needs, we are not only supporting infrastructure development but also contributing to national progress and social well-being. Resilient infrastructure is particularly critical in a context of increasing climate vulnerability, as it provides protection against extreme weather events and enhances the long-term sustainability of communities and cities.

One of the most effective platforms for showcasing the great benefits of concrete and building solutions, while contributing to national development is the “Obras por Impuestos” (Works for Taxes) program. This innovative Peruvian mechanism allows private companies to finance public infrastructure projects in advance of their income tax payments, in exchange for certificates that offset those obligations. As one of the leading contributors to this program, we ensure that critical infrastructure is delivered with quality, durability, and efficiency. The concrete roads we’ve built through this mechanism have already withstood extreme rainfall events such as El Niño and Cyclone Yaku—demonstrating the benefits of concrete, especially in areas with heavy rain, as well as the importance of resilient construction.

In addition, we are using AI-based tools to identify public infrastructure projects within our area of influence. This prospective work, supported by technology, has significantly streamlined and enhanced our project pipeline, enabling our teams to focus on delivering tailored, high-impact building solutions, rather than spending time doing it manually. This shift has supported the continued growth of our concrete and building solutions business.

Finally, as none of these results would be possible without the commitment of our talented team, we would like to briefly highlight that for the seventh consecutive year, we were recognized as the top-ranked cement company in the MERCO Talent index, and we ranked 19th across all industries. We view talent as our greatest competitive advantage, and this recognition reinforces our commitment to attracting and developing the best professionals in the market.

To sum up, this quarter continued to reflect a positive trend in demand, and we are confident this momentum will carry through the remainder of the year. We remain steadfast in our commitment to sustainable development by delivering resilient, high-quality infrastructure that improves connectivity, strengthens climate resilience, and creates lasting value for the people of Northern Peru.

ECONOMIC OVERVIEW 2Q25:

During the second quarter of 2025, the Peruvian economy continued on its recovery path, with GDP growth close to 3.0% year-over-year, driven mainly by construction, agribusiness, and non-traditional exports, according to the Peruvian Central Bank. The outlook for the remainder of the year remains optimistic. Peru’s Central Reserve Bank projects GDP growth of approximately 3.1% for all of 2025, depending on global economic stability.

Agribusiness showed sustained recovery after weather-related disruptions the previous year. Crops such as avocados, blueberries and grapes in the North of Peru achieved good yields. This is particularly relevant considering that agribusiness represents almost a third of formal employment in the North. The level of employment has a direct effect on self-construction demand.

This year, public investment will grow for the second consecutive year and will reach a record level. This will be mainly due to two factors. Firstly, the progress of the projects in charge of the National Infrastructure Authority – previously under the Authority for Reconstruction with Changes –, developed through the “Government to Government” scheme, where a foreign State advises the Peruvian State in the execution of works. These projects include flood prevention works, such as the construction of dams and riverbank defenses mostly located in La Libertad and Lambayeque, as well as new storm drainage systems in Piura and Tumbes.

Secondly, the launch of new public investment projects is expected under the traditional state contracting scheme, as well as through Public Private Partnerships. According to Apoyo Consultoria, the northern zone concentrates the largest number of projects with a value greater than S/ 50 million, whose execution would take place mainly in 2025 and 2026.

Overall, the second quarter reflected an economy that, despite external and internal challenges, continues to consolidate its recovery in a steady and resilient manner.

PERUVIAN CEMENT INDUSTRY OVERVIEW:

The demand for cement in Peru is covered mainly by Pacasmayo, UNACEM and Cementos Yura, and to a lesser extent by Caliza Inca, Holcim, imports and other small producers. Pacasmayo mainly covers the demand in the northern region of the country, while UNACEM covers the central region and Cementos Yura the southern region region.

The northern region of Peru, according to the Instituto Nacional de Estadística e Informática (INEI) and Apoyo Consultoría, represents approximately 32.9% of the country’s population and 20.0% of national Gross Domestic Product (“GDP”). Despite the country’s sustained growth over the last 10 years, Peru continues to have a significant housing deficit, estimated at 1.7 million households throughout the country as per the Ministry of Housing, Construction and Sanitation (80% qualitative and 20% quantitative deficit).

In Peru, the majority of cement is sold to a highly fragmented consumer base of individuals that tend to gradually buy bags of cement to build or to improve their homes, a segment the industry refers to as “self-construction”.

SALES OF GOODS

The following table shows the Sales of Goods and their respective margins by business segment:

Sales: cement, concrete and precast

(in millions of Soles S/)

Sales of cement, concrete and precast increased 6.7% in 2Q25 and 6.6% in 6M25, when compared to 2Q24 and 6M24 respectively, mainly due increased sales of bagged cement and concrete and pavement. Gross margin increased 2.0 percentage points during 2Q25 and 1.1 percentage points during 6M25, when compared to 2Q24 and 6M24 respectively, mainly due to operational efficiencies in cement production.

Sales: cement

(in millions of Soles S/)

Sales of cement represented 83.7% of cement, concrete and precast sales during 2Q25.

Sales of cement increased 6.3% in 2Q25 compared to 2Q24 and 5.0% in 6M25 compared to 6M24, mainly due to increased demand for cement bags from the self-construction segment. Gross margin increased 3.2 percentage points in 2Q25 and 2.9 percentage points during 6M25, when compared to 2Q24 and 6M24 respectively mainly due to lower raw material costs and our annual production plan, which aims to produce at optimal capacity during certain periods to maximize efficiency.

Sales: concrete, pavement and mortar

(in millions of Soles S/)

Sales of concrete, pavement and mortar represented 14.6% of cement, concrete, and precast sales during 2Q25.

Sales of concrete, pavement and mortar increased 9.8% during 2Q25 and 16.1% in 6M25 compared to 2Q24 and 6M24 respectively, mainly due to increased sales volume of concrete and pavement for infrastructure projects. Gross margin decreased 3.2 percentage points in 2Q25 compared to 2Q24 and 4.8 percentage points in 6M25 compared to 6M24. This decrease was mainly due to the execution of the Piura airport project. There is a difference in exchange rate between the rate projected in the contract versus the real exchange rate, as well as increased costs related to the execution of the Piura airport project, as it extended over our planned execution period. However, this extension did not imply a breach of contract, as the agreed-upon deadline with the client was not exceeded. We remain confident that developing building solutions is the right path for our company, even if it entails some short-term learning curve additional costs.
