THE ALGER FUNDS II 2026-02-27 Alger Spectra Fund Investment Objective Alger Spectra Fund seeks long-term capital appreciation. Fund Fees and Expenses This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and examples below.You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $25,000 in Class A Shares of the Alger Family of Funds, including the Fund. More information about these and other discounts is available from your financial professional and in “Purchasing and Redeeming Fund Shares” on page 35 and in Appendix A – Waivers and Discounts Available from Intermediaries on page A-1 in the Fund’s Prospectus, and in the sections “Right of Accumulation (Class A Shares)” and “Letter of Intent (Class A)” beginning on page 40 of the Fund’s Statement of Additional Information. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $25,000 in Class A Shares of the Alger Family of Funds, including the Fund.The Fund and Fred Alger Management, LLC (the “Manager”) have adopted fee breakpoints for the Fund. The advisory fee for assets up to $2 billion is .90%, for assets between $2 billion and $4 billion is .75%, for assets between $4 billion and $6 billion is .65%, for assets between $6 billion and $8 billion is .55%, and for assets in excess of $8 billion is .45%. The actual rate paid as a percentage of average daily net assets for the year ended October 31, 2025 was .83%. 25000 Shareholder Fees (fees paid directly from your investment) 0.0525 0 0 0.0100 Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment) 0.0083 0.0083 0.0025 0.0100 0.0045 0.0047 0.0153 0.0230 Purchases of $1 million or more of Class A Shares at net asset value may be subject to a contingent deferred sales charge of 1.00% on redemptions made within 12 months of purchase. Example The following examples are intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The examples assume that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods, that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be: 672 983 1315 2253 333 718 1230 2636 You would pay the following expenses if you did not redeem your shares: 233 718 1230 2636 Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the examples, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 51.13% of the average value of its portfolio. 0.5113 Principal Investment Strategy The Manager believes companies undergoing Positive Dynamic Change offer the best opportunities. Positive Dynamic Change refers to companies realizing High Unit Volume Growth or companies undergoing Positive Lifecycle Change. High Unit Volume Growth companies are traditional growth companies experiencing, for example, rapidly growing demand or market dominance. Positive Lifecycle Change companies are, for example, companies benefitting from new regulations, a new product innovation or new management.The Fund invests primarily in the equity securities of companies of any size that the Manager believes demonstrate promising growth potential. Equity securities include common or preferred stocks that are listed on U.S. or foreign exchanges.The Fund may sell securities short, which is the sale of a security the Fund does not own either to hedge a portfolio position or to seek to profit on the decline in value of the securities sold. The Fund arranges with a broker to borrow the security being sold short, and replaces the security by buying it at the current market price when it closes out the short sale. If the price of the security sold short has increased since the time of the short sale, the Fund will incur a loss in addition to the costs associated with establishing, maintaining and closing out the short position. If the price of the security sold short has decreased since the time of the short sale, the Fund will experience a gain to the extent the difference in price is greater than these costs. The Fund generally will not make a short sale if, after giving effect to such sale, the market value of all securities sold short exceeds 10% of the value of its net assets.The Fund may invest a significant portion of its assets in securities of companies conducting business within a single sector, as defined by third party sources, including, but not limited to, the information technology, consumer discretionary, and communication services sectors. For the purpose of categorizing companies, sectors are a broader category than industries and industries comprise sectors.The Fund can use leverage, that is, borrow money to purchase additional securities.The Fund may sell a stock when it reaches a target price, it fails to perform as expected, or other opportunities appear more attractive. As a result, the Fund may engage in active trading of portfolio securities.The Fund can also invest in privately placed securities, which are securities acquired in non-public offerings for which there is no readily available market.The Fund can invest in foreign securities.The Fund may invest in cash (and cash equivalents) when the Fund is unable to find enough attractive long-term investments to meet its investment objective, to meet redemptions and/or when the Manager believes it is advisable to do so during times of short-term market volatility. During these times, cash (and cash equivalents) will not exceed 15% of the Fund’s net assets. The Fund’s share price may go down, which means you could lose money. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Investment Risk – An investment in the Fund is subject to investment risk, including the possible loss of the entire principal amount that you invest. Market Risk – Your investment in Fund shares represents an indirect investment in the securities owned by the Fund. The value of these securities, like other investments, may move up or down, sometimes rapidly and unpredictably. Your Fund shares at any point in time may be worth less than what you invested, even after taking into account the reinvestment of Fund dividends and distributions. Local, regional or global events such as environmental or natural disasters, war, terrorism, pandemics, outbreaks of infectious diseases, and similar public health threats, trade disputes and changes in trade regulations, civil unrest, recessions, or other events could have a significant impact on the Fund and its investments. Equity Securities Risk – As with any fund that invests in stocks, your investment will fluctuate in value, and the loss of your investment is a risk of investing. The Fund’s price per share will fluctuate due to changes in the market prices of its investments. Also, the Fund’s investments may not grow as fast as the rate of inflation and stocks tend to be more volatile than some other investments you could make, such as bonds. Growth Securities Risk – Prices of growth stocks tend to be higher in relation to their companies’ earnings and may be more sensitive to market, political and economic developments than other stocks, making their prices more volatile. An investment in the Fund may be better suited to investors who seek long-term capital growth and can tolerate fluctuations in their investment’s value. Short Sales Risk – Because making short sales in securities that it does not own exposes the Fund to the risks associated with those securities, such short sales involve speculative exposure risk. The market price of a security may increase after the Fund borrows the security in order to sell it short, so that the Fund suffers a loss when it replaces the borrowed security at the higher price. The use of short sales could increase the Fund’s exposure to the market, magnifying losses and increasing volatility. Short sale transactions involve leverage because they can provide investment exposure in an amount exceeding the initial investment. Although the Fund’s gain is limited to the amount at which it sold a security short, its potential loss is limited only by the maximum attainable price of the security, less the price at which the security was sold and may, theoretically, be unlimited. Sector Risk – The Fund may have a significant portion of its assets invested in securities of companies conducting business within a single sector, as defined by third party sources. Companies in the same sector may be similarly affected by economic, regulatory, political or market events or conditions, which may make the Fund more vulnerable to unfavorable developments in that sector than a fund that has a more diversified portfolio. Generally, the more broadly the Fund invests, the more it spreads risk and potentially reduces the risks of loss and volatility. ●Information Technology Sector Risk – The Fund may have a significant portion of its assets invested in securities of technology-related companies. Therefore, the Fund may be more susceptible to particular risks that may affect companies in the information technology sector and technology-related sectors than if it were invested in a wider variety of companies in unrelated sectors. At times, the performance of such companies will lag the performance of other industries or the broader market as a whole. Certain technology related companies may face special risks that their products or services may not prove to be commercially successful. Technology related companies are also strongly affected by worldwide scientific or technological developments. As a result, their products may rapidly become obsolete. Such companies are also often subject to governmental regulation and may, therefore, be adversely affected by governmental policies. These factors may lead to limited earnings and/or failing profit margins. As a result, the value of technology related companies’ securities may fall or fail to rise. Many technology related companies’ securities have historically been more volatile than other securities, especially over the short term. ●Consumer Discretionary Sector Risk – The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, competition, consumers’ disposable income, consumer preferences, social trends and marketing campaigns. ●Communication Services Sector Risk – Communication services companies are particularly vulnerable to the potential obsolescence of products and services due to technological advancement and the innovation of competitors. Companies in the communication services sector may also be affected by other competitive pressures, such as pricing competition, as well as research and development costs, substantial capital requirements and government regulation. Additionally, fluctuating domestic and international demand, shifting demographics and often unpredictable changes in consumer tastes can drastically affect a communication services company’s profitability. While all companies may be susceptible to network security breaches, certain companies in the communication services sector may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses. Privately Placed Securities Risk – A private placement is an offering of a company’s securities that is not registered with the Securities and Exchange Commission (the “SEC”) and is not offered to the public. The issuers of privately placed securities are not typically subject to the same oversight and regulatory requirements, including disclosure and other investor protection requirements, to which public issuers are subject, and there may be very little public information available about the issuers and their performance. The sale or transfer of privately placed securities may be limited or prohibited by contract or law and such investments are generally considered to be illiquid. Privately placed securities are generally fair valued as they are not traded frequently. The Fund may be required to hold such positions for several years, if not longer, regardless of valuation, which may cause the Fund to be less liquid. As a result, investments in private placements can result in substantial or complete losses. Foreign Securities Risk – The Fund’s performance will be influenced by political, social and economic factors affecting investments in foreign companies. Special risks associated with investments in foreign companies include exposure to currency fluctuations, lack of liquidity, potential for market manipulation, less developed or less efficient trading markets, limited access to reliable capital, lack of comprehensive company information, political instability, differing audit, regulatory, and legal standards and lack of financial reporting standards. Additionally, events and evolving conditions in certain markets or regions may alter the risk profile of investments tied to those markets or regions. This may cause investments tied to such markets or regions to become riskier or more volatile, even when investments in such markets or regions were perceived as comparatively stable historically. In addition, foreign companies with securities listed on U.S. exchanges may be delisted if they do not meet U.S. accounting standards and auditor oversight requirements, which may decrease the liquidity and value of the securities. Leverage Risk – The cost of borrowing money to leverage may exceed the returns for the securities purchased or the securities purchased may actually go down in value; thus, the Fund’s net asset value may decrease more quickly than if the Fund had not borrowed. Cash Position Risk – At times, the Fund may hold up to 15% of its net assets in cash (and cash equivalents), which may underperform relative to equity securities.

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the examples, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 8.97% of the average value of its portfolio. 0.0897 Principal Investment Strategy The Manager believes companies undergoing Positive Dynamic Change offer the best opportunities. Positive Dynamic Change refers to companies realizing High Unit Volume Growth or companies undergoing Positive Lifecycle Change. High Unit Volume Growth companies are traditional growth companies experiencing, for example, rapidly growing demand or market dominance. Positive Lifecycle Change companies are, for example, companies benefitting from new regulations, a new product innovation or new management.Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of companies of any size with an environmental, social and governance (“ESG”) rating of average or above by a third-party ESG rating agency (an “ESG Rating Agency”) that also demonstrate, in the view of the Manager, promising growth potential. Equity securities include common or preferred stocks that are listed on U.S. or foreign exchanges. The Manager employs fundamental analysis to identify innovative and dynamic companies and uses an ESG Rating Agency’s ratings to consider how such stocks rank within an industry or sector based on a company’s conduct in offering products or services that promote positive environmental, social and/or governance policies, or have a positive impact in these areas, addressing concerns such as climate change, resource depletion, health and safety, employee relations and diversity, bribery and corruption, and fostering board diversity and structure. The Fund does not bar companies in any industries.The Fund may invest a significant portion of its assets in securities of companies conducting business within a single sector, as defined by third party sources, including, but not limited to, the information technology, consumer discretionary, and communication services sectors. For the purpose of categorizing companies, sectors are a broader category than industries and industries comprise sectors.The Fund may sell a stock when it reaches a target price, it fails to perform as expected, or other opportunities appear more attractive.

An investment in the Fund may be better suited to investors who seek long-term capital growth and can tolerate fluctuations in their investment’s value. Environmental, Social and/or Governance Sustainability-Related Securities Risk – The Fund’s ESG investment criteria may result in the selection or exclusion of securities of certain issuers for reasons other than financial performance, and carries the risk that the Fund’s investment returns may underperform funds that do not utilize an ESG investment strategy. The application of this strategy may affect the Fund’s investment exposure to certain companies, sectors, regions, countries or types of investments, which could negatively impact the Fund’s performance depending on whether such investments are in or out of favor. Applying ESG criteria to investment decisions is qualitative and subjective by nature, and there is no guarantee that the criteria utilized by the Manager or any judgment exercised by the Manager will reflect the beliefs or values of any particular investor. ESG standards differ by region and industry, and a company’s ESG practices or the Manager’s assessment of a company’s ESG practices may change over time. Sector Risk – The Fund may have a significant portion of its assets invested in securities of companies conducting business within a single sector, as defined by third party sources.

The actual rate paid as a percentage of average daily net assets for the year ended October 31, 2025 was 1.20%. 25000 Shareholder Fees (fees paid directly from your investment) 0.0525 0 0 0.0100 Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment) 0.0120 0.0120 0.0025 0.0100 0.0055 0.0058 0.0200 0.0278 Purchases of $1 million or more of Class A Shares at net asset value may be subject to a contingent deferred sales charge of 1.00% on redemptions made within 12 months of purchase. October 31, 2027 Example The following examples are intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The examples assume that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods, that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be: 717 1120 1546 2730 381 862 1469 3109 You would pay the following expenses if you did not redeem your shares: 281 862 1469 3109 Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the examples, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 376.53% of the average value of its portfolio. 3.7653 Principal Investment Strategy The Manager believes companies undergoing Positive Dynamic Change offer the best opportunities. Positive Dynamic Change refers to companies realizing High Unit Volume Growth or companies undergoing Positive Lifecycle Change. High Unit Volume Growth companies are traditional growth companies experiencing, for example, rapidly growing demand or market dominance. Positive Lifecycle Change companies are, for example, companies benefitting from new regulations, a new product innovation or new management.A portion of the Fund’s assets are sub-advised by Weatherbie Capital, LLC (“Weatherbie”), an affiliate of the Manager (Weatherbie and the Manager, collectively referred to as the “Manager,” where applicable).The Fund invests in a portfolio of U.S. and foreign equity securities (common stocks, preferred stocks and convertible securities). In addition to purchasing securities (i.e., taking long positions), the Manager will identify securities that it believes will underperform on an absolute or relative basis and will sell these securities short on behalf of the Fund. The Fund will not, however, follow a market neutral strategy and generally will have a net long position. As a result, and as a result of the cash proceeds the Fund will receive from selling securities short, the Fund will generally maintain significant positions in cash and cash equivalents. The Fund may also seek to manage the volatility of either the portfolio, a particular exposure (e.g., sector or industry) of the portfolio or individual securities through short sales, or buying or selling put or call options primarily for hedging purposes. The Fund arranges with a broker to borrow the security being sold short, and replaces the security by buying it at the current market price when it closes out the short sale. If the price of the security sold short has increased since the time of the short sale, the Fund will incur a loss in addition to the costs associated with establishing, maintaining and closing out the short position. If the price of the security sold short has decreased since the time of the short sale, the Fund will experience a gain to the extent the difference in price is greater than these costs. The Fund has no specific guidelines or restrictions governing the concentration of the Fund’s portfolio in specific entities, sectors or market capitalizations. Accordingly, the Fund may invest a portion of its assets in securities issued by small capitalization companies. The Fund may also invest a portion of its assets in equity securities not listed on an exchange.The Fund may invest a significant portion of its assets in securities of companies conducting business within a single sector, as defined by third party sources, including, but not limited to, the information technology, health care, and communication services sectors. For the purpose of categorizing companies, sectors are a broader category than industries and industries comprise sectors.The Fund can also invest in privately placed securities, which are securities acquired in non-public offerings for which there is no readily available market.The Fund may sell a stock when it reaches a target price, it fails to perform as expected, or other opportunities appear more attractive. As a result, the Fund may engage in active trading of portfolio securities.The Fund can use leverage, that is, borrow money to purchase additional securities. The Fund’s share price may go down, which means you could lose money. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Investment Risk – An investment in the Fund is subject to investment risk, including the possible loss of the entire principal amount that you invest. Market Risk – Your investment in Fund shares represents an indirect investment in the securities owned by the Fund. The value of these securities, like other investments, may move up or down, sometimes rapidly and unpredictably. Your Fund shares at any point in time may be worth less than what you invested, even after taking into account the reinvestment of Fund dividends and distributions. Local, regional or global events such as environmental or natural disasters, war, terrorism, pandemics, outbreaks of infectious diseases, and similar public health threats, trade disputes and changes in trade regulations, civil unrest, recessions, or other events could have a significant impact on the Fund and its investments. Options Risk – Price movements in the Fund’s portfolio securities may not correlate precisely with movements of the price of the option selected as a hedge. The Fund may lose money and be forced to liquidate portfolio securities to meet settlement obligations. Short Sales Risk – Because making short sales in securities that it does not own exposes the Fund to the risks associated with those securities, such short sales involve speculative exposure risk. The market price of a security may increase after the Fund borrows the security in order to sell it short, so that the Fund suffers a loss when it replaces the borrowed security at the higher price. The use of short sales could increase the Fund’s exposure to the market, magnifying losses and increasing volatility. Short sale transactions involve leverage because they can provide investment exposure in an amount exceeding the initial investment. Although the Fund’s gain is limited to the amount at which it sold a security short, its potential loss is limited only by the maximum attainable price of the security, less the price at which the security was sold and may, theoretically, be unlimited. Equity Securities Risk – As with any fund that invests in stocks, your investment will fluctuate in value, and the loss of your investment is a risk of investing. The Fund’s price per share will fluctuate due to changes in the market prices of its investments. Also, the Fund’s investments may not grow as fast as the rate of inflation and stocks tend to be more volatile than some other investments you could make, such as bonds. Growth Securities Risk – Prices of growth stocks tend to be higher in relation to their companies’ earnings and may be more sensitive to market, political and economic developments than other stocks, making their prices more volatile. An investment in the Fund may be better suited to investors who seek long-term capital growth and can tolerate fluctuations in their investment’s value. Sector Risk – The Fund may have a significant portion of its assets invested in securities of companies conducting business within a single sector, as defined by third party sources. Companies in the same sector may be similarly affected by economic, regulatory, political or market events or conditions, which may make the Fund more vulnerable to unfavorable developments in that sector than a fund that has a more diversified portfolio. Generally, the more broadly the Fund invests, the more it spreads risk and potentially reduces the risks of loss and volatility. ●Information Technology Sector Risk – The Fund may have a significant portion of its assets invested in securities of technology-related companies. Therefore, the Fund may be more susceptible to particular risks that may affect companies in the information technology sector and technology-related sectors than if it were invested in a wider variety of companies in unrelated sectors. At times, the performance of such companies will lag the performance of other industries or the broader market as a whole. Certain technology related companies may face special risks that their products or services may not prove to be commercially successful. Technology related companies are also strongly affected by worldwide scientific or technological developments. As a result, their products may rapidly become obsolete. Such companies are also often subject to governmental regulation and may, therefore, be adversely affected by governmental policies. These factors may lead to limited earnings and/or failing profit margins. As a result, the value of technology related companies’ securities may fall or fail to rise. Many technology related companies’ securities have historically been more volatile than other securities, especially over the short term. ●Health Care Sector Risk – The Fund may have a significant portion of its assets invested in securities of healthcare companies. At times, the performance of healthcare companies will lag the performance of other industries or the broader market as a whole, and the performance of such companies may be more volatile. Healthcare companies may also be significantly affected by intense competition, aggressive pricing, government regulation, technological innovations, product obsolescence, patent considerations, product compatibility and consumer preferences. ●Communication Services Sector Risk – Communication services companies are particularly vulnerable to the potential obsolescence of products and services due to technological advancement and the innovation of competitors. Companies in the communication services sector may also be affected by other competitive pressures, such as pricing competition, as well as research and development costs, substantial capital requirements and government regulation. Additionally, fluctuating domestic and international demand, shifting demographics and often unpredictable changes in consumer tastes can drastically affect a communication services company’s profitability. While all companies may be susceptible to network security breaches, certain companies in the communication services sector may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses. Privately Placed Securities Risk – A private placement is an offering of a company’s securities that is not registered with the Securities and Exchange Commission (the “SEC”) and is not offered to the public. The issuers of privately placed securities are not typically subject to the same oversight and regulatory requirements, including disclosure and other investor protection requirements, to which public issuers are subject, and there may be very little public information available about the issuers and their performance. The sale or transfer of privately placed securities may be limited or prohibited by contract or law and such investments are generally considered to be illiquid. Privately placed securities are generally fair valued as they are not traded frequently. The Fund may be required to hold such positions for several years, if not longer, regardless of valuation, which may cause the Fund to be less liquid. As a result, investments in private placements can result in substantial or complete losses. Foreign Securities Risk – The Fund’s performance will be influenced by political, social and economic factors affecting investments in foreign companies. Special risks associated with investments in foreign companies include exposure to currency fluctuations, lack of liquidity, potential for market manipulation, less developed or less efficient trading markets, limited access to reliable capital, lack of comprehensive company information, political instability, differing audit, regulatory, and legal standards and lack of financial reporting standards. Additionally, events and evolving conditions in certain markets or regions may alter the risk profile of investments tied to those markets or regions. This may cause investments tied to such markets or regions to become riskier or more volatile, even when investments in such markets or regions were perceived as comparatively stable historically. In addition, foreign companies with securities listed on U.S. exchanges may be delisted if they do not meet U.S. accounting standards and auditor oversight requirements, which may decrease the liquidity and value of the securities. Convertible Securities Risk – Issuers of convertible securities may not be as strong financially as other companies, and may be more vulnerable to changes in the economy. Small Cap Securities Risk – There may be greater risk in investing in companies with small market capitalizations rather than larger, more established companies owing to such factors as more limited product lines or financial resources or lack of management depth. It may also be difficult or impossible to liquidate a security position at a time and price acceptable to the Fund because of the potentially less frequent trading of stocks of smaller market capitalization. Leverage Risk – The cost of borrowing money to leverage may exceed the returns for the securities purchased or the securities purchased may actually go down in value; thus, the Fund’s net asset value may decrease more quickly than if the Fund had not borrowed. Portfolio Turnover (Active Trading) Risk – Because the Fund may engage in active trading of portfolio securities, it may incur increased transaction costs and brokerage commissions, both of which can lower the actual return on an investment. Active trading may also increase short-term gains and losses, which may affect the taxes a shareholder has to pay. Cash Position Risk – At times, the Fund may hold a significant portion of its net assets in cash (and cash equivalents), which may underperform relative to equity securities.

October 31, 2027 Example The following examples are intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The examples assume that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods, that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. The examples also assume that the contractual fee waiver and/or expense reimbursement is only in effect through October 31, 2027. Although your actual costs may be higher or lower, based on these assumptions your costs would be: 674 1056 1496 2715 333 795 1421 3108 You would pay the following expenses if you did not redeem your shares: 233 795 1421 3108 Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the examples, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 52.39% of the average value of its portfolio. 0.5239 Principal Investment Strategy The Fund is sub-advised by Redwood Investments, LLC (“Redwood”), an affiliate of the Manager (Redwood and the Manager, collectively referred to as the “Manager,” where applicable). Subject to the general supervision by the Fund’s Board of Trustees, the Manager oversees Redwood and evaluates its performance results. The Manager reviews portfolio performance, compliance with investment guidelines and federal securities laws, and changes in key personnel of Redwood. Redwood is primarily responsible for the day-to-day management of the Fund’s portfolio, including purchases and sales of individual securities.The Fund invests in companies that it believes meet three primary criteria: (1) high quality companies, (2) which are attractively valued, and (3) where the Manager believes that future earnings and free cash flow growth will be meaningfully above what is expected by the market. High quality companies are those companies that offer strong earnings visibility and sustainability because of their durable competitive advantages, capable management teams, and prudent financial management. The Manager focuses on understanding industry and company dynamics to assess company quality, and on identifying and forecasting critical drivers to reach a differentiated view of future growth. The Fund is an all-cap, all-country, opportunistic focus fund which generally holds less than 50 holdings. Fund holdings may differ from this number for a variety of reasons, including, among others, because of extreme market volatility, such as when the Fund has entered a temporary defensive position. Additionally, the Fund may exceed the stated number of holdings when it acquires a new holding and determines that it is in the best interests of shareholders to sell an existing holding over a period of time, instead of immediately selling the entire holding. Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities, including common stocks, American Depositary Receipts and Global Depositary Receipts, of emerging country issuers. The Manager may consider classifications including those of the World Bank, the International Finance Corporation, or the United Nations (and its agencies) in determining whether a country is an emerging country. Emerging countries include, but are not limited to, the countries that comprise the MSCI Emerging Markets Index. Currently, most Central and South American, African, Asian and Eastern European nations, among others, are considered emerging countries. The Fund may invest up to 20% of its net assets in equity securities, including common stocks, American Depositary Receipts and Global Depositary Receipts, of frontier country issuers. Frontier countries include, but are not limited to, the countries that comprise the MSCI Frontier Markets Index. For purposes of the Fund’s investment strategies, the issuer of a security is considered to be located in a country if: (i) the company is organized under the laws of, or has a principal office in that country, (ii) the company’s securities are primarily listed in that country, or (iii) a majority of its assets are in, or a majority of its revenue or profits from businesses, investments or sales are from, that country. An emerging or frontier country issuer may also include an exchange-traded fund that is principally invested in equity securities of emerging or frontier market country issuers. The Fund generally invests in at least three emerging countries, and, at times, may invest a substantial portion of its assets in a single emerging country. The Fund may invest in companies of any market capitalization, from larger, well-established companies to small, emerging growth companies. The Fund generally invests a substantial portion of its assets in a smaller number of issuers. The Fund may invest a significant portion of its assets in securities of companies conducting business within a single sector, as defined by third party sources, including, but not limited to, the consumer discretionary, financials, information technology, communication services, and industrials sectors. For the purpose of categorizing companies, sectors are a broader category than industries and industries comprise sectors.The Fund may sell a stock when it reaches a target price, it fails to perform as expected, or other opportunities appear more attractive. As a result, the Fund may engage in active trading of portfolio securities.The Fund may invest in cash (and cash equivalents) when the Fund is unable to find enough attractive long-term investments to meet its investment objective, to meet redemptions and/or when the Manager believes it is advisable to do so during times of short-term market volatility. During these times, cash (and cash equivalents) will not exceed 15% of the Fund’s net assets. The Fund’s share price may go down, which means you could lose money. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Investment Risk – An investment in the Fund is subject to investment risk, including the possible loss of the entire principal amount that you invest. Market Risk – Your investment in Fund shares represents an indirect investment in the securities owned by the Fund. The value of these securities, like other investments, may move up or down, sometimes rapidly and unpredictably. Your Fund shares at any point in time may be worth less than what you invested, even after taking into account the reinvestment of Fund dividends and distributions. Local, regional or global events such as environmental or natural disasters, war, terrorism, pandemics, outbreaks of infectious diseases, and similar public health threats, trade disputes and changes in trade regulations, civil unrest, recessions, or other events could have a significant impact on the Fund and its investments. Equity Securities Risk – As with any fund that invests in stocks, your investment will fluctuate in value, and the loss of your investment is a risk of investing. The Fund’s price per share will fluctuate due to changes in the market prices of its investments. Also, the Fund’s investments may not grow as fast as the rate of inflation and stocks tend to be more volatile than some other investments you could make, such as bonds. Growth Securities Risk – Prices of growth stocks tend to be higher in relation to their companies’ earnings and may be more sensitive to market, political and economic developments than other stocks, making their prices more volatile. An investment in the Fund may be better suited to investors who seek long-term capital growth and can tolerate fluctuations in their investment’s value. Foreign Securities Risk – The Fund’s performance will be influenced by political, social and economic factors affecting investments in foreign companies. Special risks associated with investments in foreign companies include exposure to currency fluctuations, lack of liquidity, potential for market manipulation, less developed or less efficient trading markets, limited access to reliable capital, lack of comprehensive company information, political instability, differing audit, regulatory, and legal standards and lack of financial reporting standards. Additionally, events and evolving conditions in certain markets or regions may alter the risk profile of investments tied to those markets or regions. This may cause investments tied to such markets or regions to become riskier or more volatile, even when investments in such markets or regions were perceived as comparatively stable historically. In addition, foreign companies with securities listed on U.S. exchanges may be delisted if they do not meet U.S. accounting standards and auditor oversight requirements, which may decrease the liquidity and value of the securities. Emerging Markets Risk – The Fund may invest in issuers located in emerging markets, and therefore may be exposed to the economies, industries, securities and currency markets of such countries, which may be adversely affected by protectionist trade policies, a slow U.S. economy, political and social instability, regional and global conflicts, terrorism and war, including actions that are contrary to the interests of the United States. Emerging markets are riskier than more developed markets because they tend to develop unevenly and may never fully develop. Investments in emerging markets may be considered speculative. Emerging markets are more likely to experience hyperinflation and currency devaluations, which adversely affect returns to U.S. investors. In addition, many emerging securities markets have far lower trading volumes and less liquidity than developed markets. The Fund, individually or in combination with other shareholders, may have limited rights and remedies against emerging market issuers. Frontier Markets Risk – The Fund may invest in issuers located in frontier countries. Frontier markets are those emerging markets that are considered to be among the smallest, least mature and least liquid, and as a result, may be more likely to experience inflation, political turmoil and rapid changes in economic conditions than more developed and traditional emerging markets. Investments in frontier markets may be subject to a greater risk of loss than investments in more developed and traditional emerging markets. Frontier markets often have less uniformity in accounting, auditing and financial reporting requirements, unreliable securities valuations and greater risk associated with custody of securities. Economic, political and currency risks may be more pronounced with respect to investments in frontier markets than in emerging markets. Small Cap Securities Risk – There may be greater risk in investing in companies with small market capitalizations rather than larger, more established companies owing to such factors as more limited product lines or financial resources or lack of management depth. It may also be difficult or impossible to liquidate a security position at a time and price acceptable to the Fund because of the potentially less frequent trading of stocks of smaller market capitalization. Sector Risk – The Fund may have a significant portion of its assets invested in securities of companies conducting business within a single sector, as defined by third party sources. Companies in the same sector may be similarly affected by economic, regulatory, political or market events or conditions, which may make the Fund more vulnerable to unfavorable developments in that sector than a fund that has a more diversified portfolio. Generally, the more broadly the Fund invests, the more it spreads risk and potentially reduces the risks of loss and volatility. ●Consumer Discretionary Sector Risk – The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, competition, consumers’ disposable income, consumer preferences, social trends and marketing campaigns. ●Financials Sector Risk – The Fund may have a significant portion of its assets invested in securities of financial services companies, which means the Fund may be more affected by the performance of the financials sector than a fund that is more diversified. Financial services companies are subject to extensive governmental regulation which may limit both the amounts and types of loans and other financial commitments they can make, the interest rates and fees they can charge, the scope of their activities, the prices they can charge and the amount of capital they must maintain. Certain events in the financials sector may cause an unusually high degree of volatility in the financial markets, both domestic and foreign, and cause certain financial services companies to incur large losses. ●Information Technology Sector Risk – The Fund may have a significant portion of its assets invested in securities of technology-related companies. Therefore, the Fund may be more susceptible to particular risks that may affect companies in the information technology sector and technology-related sectors than if it were invested in a wider variety of companies in unrelated sectors. At times, the performance of such companies will lag the performance of other industries or the broader market as a whole. Certain technology related companies may face special risks that their products or services may not prove to be commercially successful. Technology related companies are also strongly affected by worldwide scientific or technological developments. As a result, their products may rapidly become obsolete. Such companies are also often subject to governmental regulation and may, therefore, be adversely affected by governmental policies. These factors may lead to limited earnings and/or failing profit margins. As a result, the value of technology related companies’ securities may fall or fail to rise. Many technology related companies’ securities have historically been more volatile than other securities, especially over the short term. ●Communication Services Sector Risk – Communication services companies are particularly vulnerable to the potential obsolescence of products and services due to technological advancement and the innovation of competitors. Companies in the communication services sector may also be affected by other competitive pressures, such as pricing competition, as well as research and development costs, substantial capital requirements and government regulation. Additionally, fluctuating domestic and international demand, shifting demographics and often unpredictable changes in consumer tastes can drastically affect a communication services company’s profitability. While all companies may be susceptible to network security breaches, certain companies in the communication services sector may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses. ●Industrials Sector Risk – The Fund may have a significant portion of its assets invested in securities of companies in the industrials sector. Industrial companies are affected by supply and demand both for their specific product or service and for industrials sector products in general. Government regulation, world events, exchange rates and economic conditions, technological developments and liabilities for environmental damage and general civil liabilities will likewise affect the performance of these companies. Aerospace and defense companies, a component of the industrials sector, can be significantly affected by government spending policies because companies involved in this industry rely, to a significant extent, on U.S. and foreign government demand for their products and services. Small Number of Holdings Risk – Under normal circumstances, the Fund invests in a small number of issuers. Therefore, the Fund’s performance may be more vulnerable to changes in the market value of a single issuer and more susceptible to risks associated with a single economic, political, or regulatory occurrence than a fund that has a higher number of holdings. Cash Position Risk – At times, the Fund may hold up to 15% of its net assets in cash (and cash equivalents), which may underperform relative to equity securities. Performance The following bar chart and the table beneath it provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year. The bar chart shows how the Fund’s average annual returns have varied over the indicated periods. The table shows how the Fund’s average annual returns compare with those of an appropriate broad-based securities market index that represents the overall equity performance of global emerging markets. Performance in the bar chart does not reflect the effect of the sales charge imposed on purchases of Class A Shares of the Fund. If the bar chart reflected the applicable sales charges, returns would be less than those shown. Before February 1, 2024, the Fund was managed by different portfolio managers. Before September 24, 2019, the Fund followed different investment strategies and was managed by different portfolio managers. Performance prior to February 1, 2024 reflects these prior management styles and does not reflect the Fund's current investment personnel and performance prior to September 24, 2019 does not reflect the Fund's current investment strategies.

Alger Spectra Fund Investment Objective Alger Spectra Fund seeks long-term capital appreciation. Fund Fees and Expenses This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and examples below. Shareholder Fees (fees paid directly from your investment) 0 Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment) 0.0083 0.0025 0.0046 0.0154 The Fund and Fred Alger Management, LLC (the “Manager”) have adopted fee breakpoints for the Fund. The advisory fee for assets up to $2 billion is .90%, for assets between $2 billion and $4 billion is .75%, for assets between $4 billion and $6 billion is .65%, for assets between $6 billion and $8 billion is .55%, and for assets in excess of $8 billion is .45%. The actual rate paid as a percentage of average daily net assets for the year ended October 31, 2025 was .83%. Example The following example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods, that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be: 157 486 839 1834 Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 51.13% of the average value of its portfolio. 0.5113 Principal Investment Strategy The Manager believes companies undergoing Positive Dynamic Change offer the best opportunities. Positive Dynamic Change refers to companies realizing High Unit Volume Growth or companies undergoing Positive Lifecycle Change. High Unit Volume Growth companies are traditional growth companies experiencing, for example, rapidly growing demand or market dominance. Positive Lifecycle Change companies are, for example, companies benefitting from new regulations, a new product innovation or new management.The Fund invests primarily in the equity securities of companies of any size that the Manager believes demonstrate promising growth potential. Equity securities include common or preferred stocks that are listed on U.S. or foreign exchanges.The Fund may sell securities short, which is the sale of a security the Fund does not own either to hedge a portfolio position or to seek to profit on the decline in value of the securities sold. The Fund arranges with a broker to borrow the security being sold short, and replaces the security by buying it at the current market price when it closes out the short sale. If the price of the security sold short has increased since the time of the short sale, the Fund will incur a loss in addition to the costs associated with establishing, maintaining and closing out the short position. If the price of the security sold short has decreased since the time of the short sale, the Fund will experience a gain to the extent the difference in price is greater than these costs. The Fund generally will not make a short sale if, after giving effect to such sale, the market value of all securities sold short exceeds 10% of the value of its net assets.The Fund may invest a significant portion of its assets in securities of companies conducting business within a single sector, as defined by third party sources, including, but not limited to, the information technology, consumer discretionary, and communication services sectors. For the purpose of categorizing companies, sectors are a broader category than industries and industries comprise sectors.The Fund can use leverage, that is, borrow money to purchase additional securities.The Fund may sell a stock when it reaches a target price, it fails to perform as expected, or other opportunities appear more attractive. As a result, the Fund may engage in active trading of portfolio securities.The Fund can also invest in privately placed securities, which are securities acquired in non-public offerings for which there is no readily available market.The Fund can invest in foreign securities.The Fund may invest in cash (and cash equivalents) when the Fund is unable to find enough attractive long-term investments to meet its investment objective, to meet redemptions and/or when the Manager believes it is advisable to do so during times of short-term market volatility. During these times, cash (and cash equivalents) will not exceed 15% of the Fund’s net assets. The Fund’s share price may go down, which means you could lose money. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Investment Risk – An investment in the Fund is subject to investment risk, including the possible loss of the entire principal amount that you invest. Market Risk – Your investment in Fund shares represents an indirect investment in the securities owned by the Fund. The value of these securities, like other investments, may move up or down, sometimes rapidly and unpredictably. Your Fund shares at any point in time may be worth less than what you invested, even after taking into account the reinvestment of Fund dividends and distributions. Local, regional or global events such as environmental or natural disasters, war, terrorism, pandemics, outbreaks of infectious diseases, and similar public health threats, trade disputes and changes in trade regulations, civil unrest, recessions, or other events could have a significant impact on the Fund and its investments. Equity Securities Risk – As with any fund that invests in stocks, your investment will fluctuate in value, and the loss of your investment is a risk of investing. The Fund’s price per share will fluctuate due to changes in the market prices of its investments. Also, the Fund’s investments may not grow as fast as the rate of inflation and stocks tend to be more volatile than some other investments you could make, such as bonds. Growth Securities Risk – Prices of growth stocks tend to be higher in relation to their companies’ earnings and may be more sensitive to market, political and economic developments than other stocks, making their prices more volatile. An investment in the Fund may be better suited to investors who seek long-term capital growth and can tolerate fluctuations in their investment’s value. Short Sales Risk – Because making short sales in securities that it does not own exposes the Fund to the risks associated with those securities, such short sales involve speculative exposure risk. The market price of a security may increase after the Fund borrows the security in order to sell it short, so that the Fund suffers a loss when it replaces the borrowed security at the higher price. The use of short sales could increase the Fund’s exposure to the market, magnifying losses and increasing volatility. Short sale transactions involve leverage because they can provide investment exposure in an amount exceeding the initial investment. Although the Fund’s gain is limited to the amount at which it sold a security short, its potential loss is limited only by the maximum attainable price of the security, less the price at which the security was sold and may, theoretically, be unlimited. Sector Risk – The Fund may have a significant portion of its assets invested in securities of companies conducting business within a single sector, as defined by third party sources. Companies in the same sector may be similarly affected by economic, regulatory, political or market events or conditions, which may make the Fund more vulnerable to unfavorable developments in that sector than a fund that has a more diversified portfolio. Generally, the more broadly the Fund invests, the more it spreads risk and potentially reduces the risks of loss and volatility. ●Information Technology Sector Risk – The Fund may have a significant portion of its assets invested in securities of technology-related companies. Therefore, the Fund may be more susceptible to particular risks that may affect companies in the information technology sector and technology-related sectors than if it were invested in a wider variety of companies in unrelated sectors. At times, the performance of such companies will lag the performance of other industries or the broader market as a whole. Certain technology related companies may face special risks that their products or services may not prove to be commercially successful. Technology related companies are also strongly affected by worldwide scientific or technological developments. As a result, their products may rapidly become obsolete. Such companies are also often subject to governmental regulation and may, therefore, be adversely affected by governmental policies. These factors may lead to limited earnings and/or failing profit margins. As a result, the value of technology related companies’ securities may fall or fail to rise. Many technology related companies’ securities have historically been more volatile than other securities, especially over the short term. ●Consumer Discretionary Sector Risk – The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, competition, consumers’ disposable income, consumer preferences, social trends and marketing campaigns. ●Communication Services Sector Risk – Communication services companies are particularly vulnerable to the potential obsolescence of products and services due to technological advancement and the innovation of competitors. Companies in the communication services sector may also be affected by other competitive pressures, such as pricing competition, as well as research and development costs, substantial capital requirements and government regulation. Additionally, fluctuating domestic and international demand, shifting demographics and often unpredictable changes in consumer tastes can drastically affect a communication services company’s profitability. While all companies may be susceptible to network security breaches, certain companies in the communication services sector may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses. Privately Placed Securities Risk – A private placement is an offering of a company’s securities that is not registered with the Securities and Exchange Commission (the “SEC”) and is not offered to the public. The issuers of privately placed securities are not typically subject to the same oversight and regulatory requirements, including disclosure and other investor protection requirements, to which public issuers are subject, and there may be very little public information available about the issuers and their performance. The sale or transfer of privately placed securities may be limited or prohibited by contract or law and such investments are generally considered to be illiquid. Privately placed securities are generally fair valued as they are not traded frequently. The Fund may be required to hold such positions for several years, if not longer, regardless of valuation, which may cause the Fund to be less liquid. As a result, investments in private placements can result in substantial or complete losses. Foreign Securities Risk – The Fund’s performance will be influenced by political, social and economic factors affecting investments in foreign companies. Special risks associated with investments in foreign companies include exposure to currency fluctuations, lack of liquidity, potential for market manipulation, less developed or less efficient trading markets, limited access to reliable capital, lack of comprehensive company information, political instability, differing audit, regulatory, and legal standards and lack of financial reporting standards. Additionally, events and evolving conditions in certain markets or regions may alter the risk profile of investments tied to those markets or regions. This may cause investments tied to such markets or regions to become riskier or more volatile, even when investments in such markets or regions were perceived as comparatively stable historically. In addition, foreign companies with securities listed on U.S. exchanges may be delisted if they do not meet U.S. accounting standards and auditor oversight requirements, which may decrease the liquidity and value of the securities. Leverage Risk – The cost of borrowing money to leverage may exceed the returns for the securities purchased or the securities purchased may actually go down in value; thus, the Fund’s net asset value may decrease more quickly than if the Fund had not borrowed. Cash Position Risk – At times, the Fund may hold up to 15% of its net assets in cash (and cash equivalents), which may underperform relative to equity securities.

If the price of the security sold short has increased since the time of the short sale, the Fund will incur a loss in addition to the costs associated with establishing, maintaining and closing out the short position. If the price of the security sold short has decreased since the time of the short sale, the Fund will experience a gain to the extent the difference in price is greater than these costs. The Fund generally will not make a short sale if, after giving effect to such sale, the market value of all securities sold short exceeds 10% of the value of its net assets.The Fund may invest a significant portion of its assets in securities of companies conducting business within a single sector, as defined by third party sources, including, but not limited to, the information technology, consumer discretionary, and communication services sectors. For the purpose of categorizing companies, sectors are a broader category than industries and industries comprise sectors.The Fund can use leverage, that is, borrow money to purchase additional securities.The Fund may sell a stock when it reaches a target price, it fails to perform as expected, or other opportunities appear more attractive. As a result, the Fund may engage in active trading of portfolio securities.The Fund can also invest in privately placed securities, which are securities acquired in non-public offerings for which there is no readily available market.The Fund can invest in foreign securities.The Fund may invest in cash (and cash equivalents) when the Fund is unable to find enough attractive long-term investments to meet its investment objective, to meet redemptions and/or when the Manager believes it is advisable to do so during times of short-term market volatility. During these times, cash (and cash equivalents) will not exceed 15% of the Fund’s net assets. The Fund’s share price may go down, which means you could lose money. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Investment Risk – An investment in the Fund is subject to investment risk, including the possible loss of the entire principal amount that you invest. Market Risk – Your investment in Fund shares represents an indirect investment in the securities owned by the Fund. The value of these securities, like other investments, may move up or down, sometimes rapidly and unpredictably. Your Fund shares at any point in time may be worth less than what you invested, even after taking into account the reinvestment of Fund dividends and distributions. Local, regional or global events such as environmental or natural disasters, war, terrorism, pandemics, outbreaks of infectious diseases, and similar public health threats, trade disputes and changes in trade regulations, civil unrest, recessions, or other events could have a significant impact on the Fund and its investments. Equity Securities Risk – As with any fund that invests in stocks, your investment will fluctuate in value, and the loss of your investment is a risk of investing. The Fund’s price per share will fluctuate due to changes in the market prices of its investments. Also, the Fund’s investments may not grow as fast as the rate of inflation and stocks tend to be more volatile than some other investments you could make, such as bonds. Growth Securities Risk – Prices of growth stocks tend to be higher in relation to their companies’ earnings and may be more sensitive to market, political and economic developments than other stocks, making their prices more volatile. An investment in the Fund may be better suited to investors who seek long-term capital growth and can tolerate fluctuations in their investment’s value. Short Sales Risk – Because making short sales in securities that it does not own exposes the Fund to the risks associated with those securities, such short sales involve speculative exposure risk. The market price of a security may increase after the Fund borrows the security in order to sell it short, so that the Fund suffers a loss when it replaces the borrowed security at the higher price. The use of short sales could increase the Fund’s exposure to the market, magnifying losses and increasing volatility. Short sale transactions involve leverage because they can provide investment exposure in an amount exceeding the initial investment. Although the Fund’s gain is limited to the amount at which it sold a security short, its potential loss is limited only by the maximum attainable price of the security, less the price at which the security was sold and may, theoretically, be unlimited. Sector Risk – The Fund may have a significant portion of its assets invested in securities of companies conducting business within a single sector, as defined by third party sources. Companies in the same sector may be similarly affected by economic, regulatory, political or market events or conditions, which may make the Fund more vulnerable to unfavorable developments in that sector than a fund that has a more diversified portfolio. Generally, the more broadly the Fund invests, the more it spreads risk and potentially reduces the risks of loss and volatility. ●Information Technology Sector Risk – The Fund may have a significant portion of its assets invested in securities of technology-related companies. Therefore, the Fund may be more susceptible to particular risks that may affect companies in the information technology sector and technology-related sectors than if it were invested in a wider variety of companies in unrelated sectors. At times, the performance of such companies will lag the performance of other industries or the broader market as a whole. Certain technology related companies may face special risks that their products or services may not prove to be commercially successful. Technology related companies are also strongly affected by worldwide scientific or technological developments. As a result, their products may rapidly become obsolete. Such companies are also often subject to governmental regulation and may, therefore, be adversely affected by governmental policies. These factors may lead to limited earnings and/or failing profit margins. As a result, the value of technology related companies’ securities may fall or fail to rise. Many technology related companies’ securities have historically been more volatile than other securities, especially over the short term. ●Consumer Discretionary Sector Risk – The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, competition, consumers’ disposable income, consumer preferences, social trends and marketing campaigns. ●Communication Services Sector Risk – Communication services companies are particularly vulnerable to the potential obsolescence of products and services due to technological advancement and the innovation of competitors. Companies in the communication services sector may also be affected by other competitive pressures, such as pricing competition, as well as research and development costs, substantial capital requirements and government regulation. Additionally, fluctuating domestic and international demand, shifting demographics and often unpredictable changes in consumer tastes can drastically affect a communication services company’s profitability. While all companies may be susceptible to network security breaches, certain companies in the communication services sector may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses. Privately Placed Securities Risk – A private placement is an offering of a company’s securities that is not registered with the Securities and Exchange Commission (the “SEC”) and is not offered to the public. The issuers of privately placed securities are not typically subject to the same oversight and regulatory requirements, including disclosure and other investor protection requirements, to which public issuers are subject, and there may be very little public information available about the issuers and their performance. The sale or transfer of privately placed securities may be limited or prohibited by contract or law and such investments are generally considered to be illiquid. Privately placed securities are generally fair valued as they are not traded frequently. The Fund may be required to hold such positions for several years, if not longer, regardless of valuation, which may cause the Fund to be less liquid. As a result, investments in private placements can result in substantial or complete losses. Foreign Securities Risk – The Fund’s performance will be influenced by political, social and economic factors affecting investments in foreign companies. Special risks associated with investments in foreign companies include exposure to currency fluctuations, lack of liquidity, potential for market manipulation, less developed or less efficient trading markets, limited access to reliable capital, lack of comprehensive company information, political instability, differing audit, regulatory, and legal standards and lack of financial reporting standards. Additionally, events and evolving conditions in certain markets or regions may alter the risk profile of investments tied to those markets or regions. This may cause investments tied to such markets or regions to become riskier or more volatile, even when investments in such markets or regions were perceived as comparatively stable historically. In addition, foreign companies with securities listed on U.S. exchanges may be delisted if they do not meet U.S. accounting standards and auditor oversight requirements, which may decrease the liquidity and value of the securities. Leverage Risk – The cost of borrowing money to leverage may exceed the returns for the securities purchased or the securities purchased may actually go down in value; thus, the Fund’s net asset value may decrease more quickly than if the Fund had not borrowed. Cash Position Risk – At times, the Fund may hold up to 15% of its net assets in cash (and cash equivalents), which may underperform relative to equity securities.

Alger Responsible Investing Fund Investment Objective Alger Responsible Investing Fund seeks long-term capital appreciation. Fund Fees and Expenses This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and examples below. Shareholder Fees (fees paid directly from your investment) 0 Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment) 0.0071 0.0025 0.0030 0.0126 -0.0016 0.0110 The Fund and Fred Alger Management, LLC (the “Manager”) have adopted fee breakpoints for the Fund. The advisory fee for assets up to $1 billion is .71%, and for assets in excess of $1 billion is .65%. The actual rate paid as a percentage of average daily net assets for the year ended October 31, 2025 was .71%. October 31, 2027 Example The following example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods, that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. The example also assumes that the contractual fee waiver and/or expense reimbursement is only in effect through October 31, 2027. Although your actual costs may be higher or lower, based on these assumptions your costs would be: 112 373 665 1499 Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 8.97% of the average value of its portfolio. 0.0897 Principal Investment Strategy The Manager believes companies undergoing Positive Dynamic Change offer the best opportunities. Positive Dynamic Change refers to companies realizing High Unit Volume Growth or companies undergoing Positive Lifecycle Change. High Unit Volume Growth companies are traditional growth companies experiencing, for example, rapidly growing demand or market dominance. Positive Lifecycle Change companies are, for example, companies benefitting from new regulations, a new product innovation or new management.Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of companies of any size with an environmental, social and governance (“ESG”) rating of average or above by a third-party ESG rating agency (an “ESG Rating Agency”) that also demonstrate, in the view of the Manager, promising growth potential. Equity securities include common or preferred stocks that are listed on U.S. or foreign exchanges. The Manager employs fundamental analysis to identify innovative and dynamic companies and uses an ESG Rating Agency’s ratings to consider how such stocks rank within an industry or sector based on a company’s conduct in offering products or services that promote positive environmental, social and/or governance policies, or have a positive impact in these areas, addressing concerns such as climate change, resource depletion, health and safety, employee relations and diversity, bribery and corruption, and fostering board diversity and structure. The Fund does not bar companies in any industries.The Fund may invest a significant portion of its assets in securities of companies conducting business within a single sector, as defined by third party sources, including, but not limited to, the information technology, consumer discretionary, and communication services sectors. For the purpose of categorizing companies, sectors are a broader category than industries and industries comprise sectors.The Fund may sell a stock when it reaches a target price, it fails to perform as expected, or other opportunities appear more attractive.

An investment in the Fund may be better suited to investors who seek long-term capital growth and can tolerate fluctuations in their investment’s value. Environmental, Social and/or Governance Sustainability-Related Securities Risk – The Fund’s ESG investment criteria may result in the selection or exclusion of securities of certain issuers for reasons other than financial performance, and carries the risk that the Fund’s investment returns may underperform funds that do not utilize an ESG investment strategy. The application of this strategy may affect the Fund’s investment exposure to certain companies, sectors, regions, countries or types of investments, which could negatively impact the Fund’s performance depending on whether such investments are in or out of favor. Applying ESG criteria to investment decisions is qualitative and subjective by nature, and there is no guarantee that the criteria utilized by the Manager or any judgment exercised by the Manager will reflect the beliefs or values of any particular investor. ESG standards differ by region and industry, and a company’s ESG practices or the Manager’s assessment of a company’s ESG practices may change over time.

The Fund’s past performance (before and after taxes) is not necessarily an indication of how it will perform in the future. www.alger.com Annual Total Return for Class Z Shares as of December 31 (%) Best Quarter:Q2 202027.70%Worst Quarter:Q2 2022-21.19% Best Quarter: 2020-06-30 0.2770 Worst Quarter: 2022-06-30 -0.2119 Average Annual Total Return as of December 31, 2025 2016-10-14 0.2249 0.1289 0.1723 0.2022 0.1165 0.1540 0.1484 0.1011 0.1389 0.1856 0.1532 0.1929 0.1788 0.1442 0.1543 In the foregoing table, after-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes.Actual after-tax returns depend on an investor’s tax situation and may differ from those shown.

Alger Dynamic Opportunities Fund Investment Objective Alger Dynamic Opportunities Fund seeks long-term capital appreciation. Fund Fees and Expenses This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and examples below. Shareholder Fees (fees paid directly from your investment) 0 Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment) 0.0120 0 0.0049 0.0169 The Fund and Fred Alger Management, LLC (the “Manager”) have adopted fee breakpoints for the Fund. The advisory fee for assets up to $1 billion is 1.20%, and for assets in excess of $1 billion is 1.00%. The actual rate paid as a percentage of average daily net assets for the year ended October 31, 2025 was 1.20%. October 31, 2027 Example The following example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods, that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. October 31, 2027 Although your actual costs may be higher or lower, based on these assumptions your costs would be: 172 533 918 1998 Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 376.53% of the average value of its portfolio. 3.7653 Principal Investment Strategy The Manager believes companies undergoing Positive Dynamic Change offer the best opportunities. Positive Dynamic Change refers to companies realizing High Unit Volume Growth or companies undergoing Positive Lifecycle Change. High Unit Volume Growth companies are traditional growth companies experiencing, for example, rapidly growing demand or market dominance. Positive Lifecycle Change companies are, for example, companies benefitting from new regulations, a new product innovation or new management.A portion of the Fund’s assets are sub-advised by Weatherbie Capital, LLC (“Weatherbie”), an affiliate of the Manager (Weatherbie and the Manager, collectively referred to as the “Manager,” where applicable).The Fund invests in a portfolio of U.S. and foreign equity securities (common stocks, preferred stocks and convertible securities). In addition to purchasing securities (i.e., taking long positions), the Manager will identify securities that it believes will underperform on an absolute or relative basis and will sell these securities short on behalf of the Fund. The Fund will not, however, follow a market neutral strategy and generally will have a net long position. As a result, and as a result of the cash proceeds the Fund will receive from selling securities short, the Fund will generally maintain significant positions in cash and cash equivalents. The Fund may also seek to manage the volatility of either the portfolio, a particular exposure (e.g., sector or industry) of the portfolio or individual securities through short sales, or buying or selling put or call options primarily for hedging purposes. The Fund arranges with a broker to borrow the security being sold short, and replaces the security by buying it at the current market price when it closes out the short sale. If the price of the security sold short has increased since the time of the short sale, the Fund will incur a loss in addition to the costs associated with establishing, maintaining and closing out the short position. If the price of the security sold short has decreased since the time of the short sale, the Fund will experience a gain to the extent the difference in price is greater than these costs. The Fund has no specific guidelines or restrictions governing the concentration of the Fund’s portfolio in specific entities, sectors or market capitalizations. Accordingly, the Fund may invest a portion of its assets in securities issued by small capitalization companies. The Fund may also invest a portion of its assets in equity securities not listed on an exchange.The Fund may invest a significant portion of its assets in securities of companies conducting business within a single sector, as defined by third party sources, including, but not limited to, the information technology, health care, and communication services sectors. For the purpose of categorizing companies, sectors are a broader category than industries and industries comprise sectors.The Fund can also invest in privately placed securities, which are securities acquired in non-public offerings for which there is no readily available market.The Fund may sell a stock when it reaches a target price, it fails to perform as expected, or other opportunities appear more attractive. As a result, the Fund may engage in active trading of portfolio securities.The Fund can use leverage, that is, borrow money to purchase additional securities. The Fund’s share price may go down, which means you could lose money. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Investment Risk – An investment in the Fund is subject to investment risk, including the possible loss of the entire principal amount that you invest. Market Risk – Your investment in Fund shares represents an indirect investment in the securities owned by the Fund. The value of these securities, like other investments, may move up or down, sometimes rapidly and unpredictably. Your Fund shares at any point in time may be worth less than what you invested, even after taking into account the reinvestment of Fund dividends and distributions. Local, regional or global events such as environmental or natural disasters, war, terrorism, pandemics, outbreaks of infectious diseases, and similar public health threats, trade disputes and changes in trade regulations, civil unrest, recessions, or other events could have a significant impact on the Fund and its investments. Options Risk – Price movements in the Fund’s portfolio securities may not correlate precisely with movements of the price of the option selected as a hedge. The Fund may lose money and be forced to liquidate portfolio securities to meet settlement obligations. Short Sales Risk – Because making short sales in securities that it does not own exposes the Fund to the risks associated with those securities, such short sales involve speculative exposure risk. The market price of a security may increase after the Fund borrows the security in order to sell it short, so that the Fund suffers a loss when it replaces the borrowed security at the higher price. The use of short sales could increase the Fund’s exposure to the market, magnifying losses and increasing volatility. Short sale transactions involve leverage because they can provide investment exposure in an amount exceeding the initial investment. Although the Fund’s gain is limited to the amount at which it sold a security short, its potential loss is limited only by the maximum attainable price of the security, less the price at which the security was sold and may, theoretically, be unlimited. Equity Securities Risk – As with any fund that invests in stocks, your investment will fluctuate in value, and the loss of your investment is a risk of investing. The Fund’s price per share will fluctuate due to changes in the market prices of its investments. Also, the Fund’s investments may not grow as fast as the rate of inflation and stocks tend to be more volatile than some other investments you could make, such as bonds. Growth Securities Risk – Prices of growth stocks tend to be higher in relation to their companies’ earnings and may be more sensitive to market, political and economic developments than other stocks, making their prices more volatile. An investment in the Fund may be better suited to investors who seek long-term capital growth and can tolerate fluctuations in their investment’s value. Sector Risk – The Fund may have a significant portion of its assets invested in securities of companies conducting business within a single sector, as defined by third party sources. Companies in the same sector may be similarly affected by economic, regulatory, political or market events or conditions, which may make the Fund more vulnerable to unfavorable developments in that sector than a fund that has a more diversified portfolio. Generally, the more broadly the Fund invests, the more it spreads risk and potentially reduces the risks of loss and volatility. ●Information Technology Sector Risk – The Fund may have a significant portion of its assets invested in securities of technology-related companies. Therefore, the Fund may be more susceptible to particular risks that may affect companies in the information technology sector and technology-related sectors than if it were invested in a wider variety of companies in unrelated sectors. At times, the performance of such companies will lag the performance of other industries or the broader market as a whole. Certain technology related companies may face special risks that their products or services may not prove to be commercially successful. Technology related companies are also strongly affected by worldwide scientific or technological developments. As a result, their products may rapidly become obsolete. Such companies are also often subject to governmental regulation and may, therefore, be adversely affected by governmental policies. These factors may lead to limited earnings and/or failing profit margins. As a result, the value of technology related companies’ securities may fall or fail to rise. Many technology related companies’ securities have historically been more volatile than other securities, especially over the short term. ●Health Care Sector Risk – The Fund may have a significant portion of its assets invested in securities of healthcare companies. At times, the performance of healthcare companies will lag the performance of other industries or the broader market as a whole, and the performance of such companies may be more volatile. Healthcare companies may also be significantly affected by intense competition, aggressive pricing, government regulation, technological innovations, product obsolescence, patent considerations, product compatibility and consumer preferences. ●Communication Services Sector Risk – Communication services companies are particularly vulnerable to the potential obsolescence of products and services due to technological advancement and the innovation of competitors. Companies in the communication services sector may also be affected by other competitive pressures, such as pricing competition, as well as research and development costs, substantial capital requirements and government regulation. Additionally, fluctuating domestic and international demand, shifting demographics and often unpredictable changes in consumer tastes can drastically affect a communication services company’s profitability. While all companies may be susceptible to network security breaches, certain companies in the communication services sector may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses. Privately Placed Securities Risk – A private placement is an offering of a company’s securities that is not registered with the Securities and Exchange Commission (the “SEC”) and is not offered to the public. The issuers of privately placed securities are not typically subject to the same oversight and regulatory requirements, including disclosure and other investor protection requirements, to which public issuers are subject, and there may be very little public information available about the issuers and their performance. The sale or transfer of privately placed securities may be limited or prohibited by contract or law and such investments are generally considered to be illiquid. Privately placed securities are generally fair valued as they are not traded frequently. The Fund may be required to hold such positions for several years, if not longer, regardless of valuation, which may cause the Fund to be less liquid. As a result, investments in private placements can result in substantial or complete losses. Foreign Securities Risk – The Fund’s performance will be influenced by political, social and economic factors affecting investments in foreign companies. Special risks associated with investments in foreign companies include exposure to currency fluctuations, lack of liquidity, potential for market manipulation, less developed or less efficient trading markets, limited access to reliable capital, lack of comprehensive company information, political instability, differing audit, regulatory, and legal standards and lack of financial reporting standards. Additionally, events and evolving conditions in certain markets or regions may alter the risk profile of investments tied to those markets or regions. This may cause investments tied to such markets or regions to become riskier or more volatile, even when investments in such markets or regions were perceived as comparatively stable historically. In addition, foreign companies with securities listed on U.S. exchanges may be delisted if they do not meet U.S. accounting standards and auditor oversight requirements, which may decrease the liquidity and value of the securities. Convertible Securities Risk – Issuers of convertible securities may not be as strong financially as other companies, and may be more vulnerable to changes in the economy. Small Cap Securities Risk – There may be greater risk in investing in companies with small market capitalizations rather than larger, more established companies owing to such factors as more limited product lines or financial resources or lack of management depth. It may also be difficult or impossible to liquidate a security position at a time and price acceptable to the Fund because of the potentially less frequent trading of stocks of smaller market capitalization. Leverage Risk – The cost of borrowing money to leverage may exceed the returns for the securities purchased or the securities purchased may actually go down in value; thus, the Fund’s net asset value may decrease more quickly than if the Fund had not borrowed. Portfolio Turnover (Active Trading) Risk – Because the Fund may engage in active trading of portfolio securities, it may incur increased transaction costs and brokerage commissions, both of which can lower the actual return on an investment. Active trading may also increase short-term gains and losses, which may affect the taxes a shareholder has to pay. Cash Position Risk – At times, the Fund may hold a significant portion of its net assets in cash (and cash equivalents), which may underperform relative to equity securities.

Alger Emerging Markets Fund Investment Objective Alger Emerging Markets Fund seeks long-term capital appreciation. Fund Fees and Expenses This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and examples below. Shareholder Fees (fees paid directly from your investment) 0 Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment) 0.0075 0.0025 0.0109 0.0209 -0.0064 0.0145 October 31, 2027 Example The following example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods, that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. The example also assumes that the contractual fee waiver and/or expense reimbursement is only in effect through October 31, 2027. Although your actual costs may be higher or lower, based on these assumptions your costs would be: 148 550 1023 2334 Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 52.39% of the average value of its portfolio. 0.5239 Principal Investment Strategy The Fund is sub-advised by Redwood Investments, LLC (“Redwood”), an affiliate of the Manager (Redwood and the Manager, collectively referred to as the “Manager,” where applicable). Subject to the general supervision by the Fund’s Board of Trustees, the Manager oversees Redwood and evaluates its performance results. The Manager reviews portfolio performance, compliance with investment guidelines and federal securities laws, and changes in key personnel of Redwood. Redwood is primarily responsible for the day-to-day management of the Fund’s portfolio, including purchases and sales of individual securities.The Fund invests in companies that it believes meet three primary criteria: (1) high quality companies, (2) which are attractively valued, and (3) where the Manager believes that future earnings and free cash flow growth will be meaningfully above what is expected by the market. High quality companies are those companies that offer strong earnings visibility and sustainability because of their durable competitive advantages, capable management teams, and prudent financial management. The Manager focuses on understanding industry and company dynamics to assess company quality, and on identifying and forecasting critical drivers to reach a differentiated view of future growth. The Fund is an all-cap, all-country, opportunistic focus fund which generally holds less than 50 holdings. Fund holdings may differ from this number for a variety of reasons, including, among others, because of extreme market volatility, such as when the Fund has entered a temporary defensive position. Additionally, the Fund may exceed the stated number of holdings when it acquires a new holding and determines that it is in the best interests of shareholders to sell an existing holding over a period of time, instead of immediately selling the entire holding. Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities, including common stocks, American Depositary Receipts and Global Depositary Receipts, of emerging country issuers. The Manager may consider classifications including those of the World Bank, the International Finance Corporation, or the United Nations (and its agencies) in determining whether a country is an emerging country. Emerging countries include, but are not limited to, the countries that comprise the MSCI Emerging Markets Index. Currently, most Central and South American, African, Asian and Eastern European nations, among others, are considered emerging countries. The Fund may invest up to 20% of its net assets in equity securities, including common stocks, American Depositary Receipts and Global Depositary Receipts, of frontier country issuers. Frontier countries include, but are not limited to, the countries that comprise the MSCI Frontier Markets Index. For purposes of the Fund’s investment strategies, the issuer of a security is considered to be located in a country if: (i) the company is organized under the laws of, or has a principal office in that country, (ii) the company’s securities are primarily listed in that country, or (iii) a majority of its assets are in, or a majority of its revenue or profits from businesses, investments or sales are from, that country. An emerging or frontier country issuer may also include an exchange-traded fund that is principally invested in equity securities of emerging or frontier market country issuers. The Fund generally invests in at least three emerging countries, and, at times, may invest a substantial portion of its assets in a single emerging country. The Fund may invest in companies of any market capitalization, from larger, well-established companies to small, emerging growth companies. The Fund generally invests a substantial portion of its assets in a smaller number of issuers. The Fund may invest a significant portion of its assets in securities of companies conducting business within a single sector, as defined by third party sources, including, but not limited to, the consumer discretionary, financials, information technology, communication services, and industrials sectors. For the purpose of categorizing companies, sectors are a broader category than industries and industries comprise sectors.The Fund may sell a stock when it reaches a target price, it fails to perform as expected, or other opportunities appear more attractive. As a result, the Fund may engage in active trading of portfolio securities.The Fund may invest in cash (and cash equivalents) when the Fund is unable to find enough attractive long-term investments to meet its investment objective, to meet redemptions and/or when the Manager believes it is advisable to do so during times of short-term market volatility. During these times, cash (and cash equivalents) will not exceed 15% of the Fund’s net assets. The Fund’s share price may go down, which means you could lose money. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Investment Risk – An investment in the Fund is subject to investment risk, including the possible loss of the entire principal amount that you invest. Market Risk – Your investment in Fund shares represents an indirect investment in the securities owned by the Fund. The value of these securities, like other investments, may move up or down, sometimes rapidly and unpredictably. Your Fund shares at any point in time may be worth less than what you invested, even after taking into account the reinvestment of Fund dividends and distributions. Local, regional or global events such as environmental or natural disasters, war, terrorism, pandemics, outbreaks of infectious diseases, and similar public health threats, trade disputes and changes in trade regulations, civil unrest, recessions, or other events could have a significant impact on the Fund and its investments. Equity Securities Risk – As with any fund that invests in stocks, your investment will fluctuate in value, and the loss of your investment is a risk of investing. The Fund’s price per share will fluctuate due to changes in the market prices of its investments. Also, the Fund’s investments may not grow as fast as the rate of inflation and stocks tend to be more volatile than some other investments you could make, such as bonds. Growth Securities Risk – Prices of growth stocks tend to be higher in relation to their companies’ earnings and may be more sensitive to market, political and economic developments than other stocks, making their prices more volatile. An investment in the Fund may be better suited to investors who seek long-term capital growth and can tolerate fluctuations in their investment’s value. Foreign Securities Risk – The Fund’s performance will be influenced by political, social and economic factors affecting investments in foreign companies. Special risks associated with investments in foreign companies include exposure to currency fluctuations, lack of liquidity, potential for market manipulation, less developed or less efficient trading markets, limited access to reliable capital, lack of comprehensive company information, political instability, differing audit, regulatory, and legal standards and lack of financial reporting standards. Additionally, events and evolving conditions in certain markets or regions may alter the risk profile of investments tied to those markets or regions. This may cause investments tied to such markets or regions to become riskier or more volatile, even when investments in such markets or regions were perceived as comparatively stable historically. In addition, foreign companies with securities listed on U.S. exchanges may be delisted if they do not meet U.S. accounting standards and auditor oversight requirements, which may decrease the liquidity and value of the securities. Emerging Markets Risk – The Fund may invest in issuers located in emerging markets, and therefore may be exposed to the economies, industries, securities and currency markets of such countries, which may be adversely affected by protectionist trade policies, a slow U.S. economy, political and social instability, regional and global conflicts, terrorism and war, including actions that are contrary to the interests of the United States. Emerging markets are riskier than more developed markets because they tend to develop unevenly and may never fully develop. Investments in emerging markets may be considered speculative. Emerging markets are more likely to experience hyperinflation and currency devaluations, which adversely affect returns to U.S. investors. In addition, many emerging securities markets have far lower trading volumes and less liquidity than developed markets. The Fund, individually or in combination with other shareholders, may have limited rights and remedies against emerging market issuers. Frontier Markets Risk – The Fund may invest in issuers located in frontier countries. Frontier markets are those emerging markets that are considered to be among the smallest, least mature and least liquid, and as a result, may be more likely to experience inflation, political turmoil and rapid changes in economic conditions than more developed and traditional emerging markets. Investments in frontier markets may be subject to a greater risk of loss than investments in more developed and traditional emerging markets. Frontier markets often have less uniformity in accounting, auditing and financial reporting requirements, unreliable securities valuations and greater risk associated with custody of securities. Economic, political and currency risks may be more pronounced with respect to investments in frontier markets than in emerging markets. Small Cap Securities Risk – There may be greater risk in investing in companies with small market capitalizations rather than larger, more established companies owing to such factors as more limited product lines or financial resources or lack of management depth. It may also be difficult or impossible to liquidate a security position at a time and price acceptable to the Fund because of the potentially less frequent trading of stocks of smaller market capitalization. Sector Risk – The Fund may have a significant portion of its assets invested in securities of companies conducting business within a single sector, as defined by third party sources. Companies in the same sector may be similarly affected by economic, regulatory, political or market events or conditions, which may make the Fund more vulnerable to unfavorable developments in that sector than a fund that has a more diversified portfolio. Generally, the more broadly the Fund invests, the more it spreads risk and potentially reduces the risks of loss and volatility. ●Consumer Discretionary Sector Risk – The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, competition, consumers’ disposable income, consumer preferences, social trends and marketing campaigns. ●Financials Sector Risk – The Fund may have a significant portion of its assets invested in securities of financial services companies, which means the Fund may be more affected by the performance of the financials sector than a fund that is more diversified. Financial services companies are subject to extensive governmental regulation which may limit both the amounts and types of loans and other financial commitments they can make, the interest rates and fees they can charge, the scope of their activities, the prices they can charge and the amount of capital they must maintain. Certain events in the financials sector may cause an unusually high degree of volatility in the financial markets, both domestic and foreign, and cause certain financial services companies to incur large losses. ●Information Technology Sector Risk – The Fund may have a significant portion of its assets invested in securities of technology-related companies. Therefore, the Fund may be more susceptible to particular risks that may affect companies in the information technology sector and technology-related sectors than if it were invested in a wider variety of companies in unrelated sectors. At times, the performance of such companies will lag the performance of other industries or the broader market as a whole. Certain technology related companies may face special risks that their products or services may not prove to be commercially successful. Technology related companies are also strongly affected by worldwide scientific or technological developments. As a result, their products may rapidly become obsolete. Such companies are also often subject to governmental regulation and may, therefore, be adversely affected by governmental policies. These factors may lead to limited earnings and/or failing profit margins. As a result, the value of technology related companies’ securities may fall or fail to rise. Many technology related companies’ securities have historically been more volatile than other securities, especially over the short term. ●Communication Services Sector Risk – Communication services companies are particularly vulnerable to the potential obsolescence of products and services due to technological advancement and the innovation of competitors. Companies in the communication services sector may also be affected by other competitive pressures, such as pricing competition, as well as research and development costs, substantial capital requirements and government regulation. Additionally, fluctuating domestic and international demand, shifting demographics and often unpredictable changes in consumer tastes can drastically affect a communication services company’s profitability. While all companies may be susceptible to network security breaches, certain companies in the communication services sector may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses. ●Industrials Sector Risk – The Fund may have a significant portion of its assets invested in securities of companies in the industrials sector. Industrial companies are affected by supply and demand both for their specific product or service and for industrials sector products in general. Government regulation, world events, exchange rates and economic conditions, technological developments and liabilities for environmental damage and general civil liabilities will likewise affect the performance of these companies. Aerospace and defense companies, a component of the industrials sector, can be significantly affected by government spending policies because companies involved in this industry rely, to a significant extent, on U.S. and foreign government demand for their products and services. Small Number of Holdings Risk – Under normal circumstances, the Fund invests in a small number of issuers. Therefore, the Fund’s performance may be more vulnerable to changes in the market value of a single issuer and more susceptible to risks associated with a single economic, political, or regulatory occurrence than a fund that has a higher number of holdings. Cash Position Risk – At times, the Fund may hold up to 15% of its net assets in cash (and cash equivalents), which may underperform relative to equity securities. Performance The following bar chart and the table beneath it provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year. The bar chart shows how the Fund’s average annual returns have varied over the indicated periods. The table shows how the Fund’s average annual returns compare with those of an appropriate broad-based securities market index that represents the overall equity performance of global emerging markets. Before February 1, 2024, the Fund was managed by different portfolio managers. Before September 24, 2019, the Fund followed different investment strategies and was managed by different portfolio managers. Performance prior to February 1, 2024 reflects these prior management styles and does not reflect the Fund's current investment personnel and performance prior to September 24, 2019 does not reflect the Fund's current investment strategies.

Alger Emerging Markets Fund Investment Objective Alger Emerging Markets Fund seeks long-term capital appreciation. Fund Fees and Expenses This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and examples below. Shareholder Fees (fees paid directly from your investment) 0 Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment) 0.0075 0 0.0096 0.0171 -0.0072 0.0099 October 31, 2027 Example The following example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods, that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. The example also assumes that the contractual fee waiver and/or expense reimbursement is only in effect through October 31, 2027. Although your actual costs may be higher or lower, based on these assumptions your costs would be: 101 419 813 1917 Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 52.39% of the average value of its portfolio. 0.5239 Principal Investment Strategy The Fund is sub-advised by Redwood Investments, LLC (“Redwood”), an affiliate of the Manager (Redwood and the Manager, collectively referred to as the “Manager,” where applicable). Subject to the general supervision by the Fund’s Board of Trustees, the Manager oversees Redwood and evaluates its performance results. The Manager reviews portfolio performance, compliance with investment guidelines and federal securities laws, and changes in key personnel of Redwood. Redwood is primarily responsible for the day-to-day management of the Fund’s portfolio, including purchases and sales of individual securities.The Fund invests in companies that it believes meet three primary criteria: (1) high quality companies, (2) which are attractively valued, and (3) where the Manager believes that future earnings and free cash flow growth will be meaningfully above what is expected by the market. High quality companies are those companies that offer strong earnings visibility and sustainability because of their durable competitive advantages, capable management teams, and prudent financial management. The Manager focuses on understanding industry and company dynamics to assess company quality, and on identifying and forecasting critical drivers to reach a differentiated view of future growth. The Fund is an all-cap, all-country, opportunistic focus fund which generally holds less than 50 holdings. Fund holdings may differ from this number for a variety of reasons, including, among others, because of extreme market volatility, such as when the Fund has entered a temporary defensive position. Additionally, the Fund may exceed the stated number of holdings when it acquires a new holding and determines that it is in the best interests of shareholders to sell an existing holding over a period of time, instead of immediately selling the entire holding. Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities, including common stocks, American Depositary Receipts and Global Depositary Receipts, of emerging country issuers. The Manager may consider classifications including those of the World Bank, the International Finance Corporation, or the United Nations (and its agencies) in determining whether a country is an emerging country. Emerging countries include, but are not limited to, the countries that comprise the MSCI Emerging Markets Index. Currently, most Central and South American, African, Asian and Eastern European nations, among others, are considered emerging countries. The Fund may invest up to 20% of its net assets in equity securities, including common stocks, American Depositary Receipts and Global Depositary Receipts, of frontier country issuers. Frontier countries include, but are not limited to, the countries that comprise the MSCI Frontier Markets Index. For purposes of the Fund’s investment strategies, the issuer of a security is considered to be located in a country if: (i) the company is organized under the laws of, or has a principal office in that country, (ii) the company’s securities are primarily listed in that country, or (iii) a majority of its assets are in, or a majority of its revenue or profits from businesses, investments or sales are from, that country. An emerging or frontier country issuer may also include an exchange-traded fund that is principally invested in equity securities of emerging or frontier market country issuers. The Fund generally invests in at least three emerging countries, and, at times, may invest a substantial portion of its assets in a single emerging country. The Fund may invest in companies of any market capitalization, from larger, well-established companies to small, emerging growth companies. The Fund generally invests a substantial portion of its assets in a smaller number of issuers. The Fund may invest a significant portion of its assets in securities of companies conducting business within a single sector, as defined by third party sources, including, but not limited to, the consumer discretionary, financials, information technology, communication services, and industrials sectorsThe Fund may sell a stock when it reaches a target price, it fails to perform as expected, or other opportunities appear more attractive. As a result, the Fund may engage in active trading of portfolio securities.The Fund may invest in cash (and cash equivalents) when the Fund is unable to find enough attractive long-term investments to meet its investment objective, to meet redemptions and/or when the Manager believes it is advisable to do so during times of short-term market volatility. During these times, cash (and cash equivalents) will not exceed 15% of the Fund’s net assets. The Fund’s share price may go down, which means you could lose money. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Investment Risk – An investment in the Fund is subject to investment risk, including the possible loss of the entire principal amount that you invest. Market Risk – Your investment in Fund shares represents an indirect investment in the securities owned by the Fund. The value of these securities, like other investments, may move up or down, sometimes rapidly and unpredictably. Your Fund shares at any point in time may be worth less than what you invested, even after taking into account the reinvestment of Fund dividends and distributions. Local, regional or global events such as environmental or natural disasters, war, terrorism, pandemics, outbreaks of infectious diseases, and similar public health threats, trade disputes and changes in trade regulations, civil unrest, recessions, or other events could have a significant impact on the Fund and its investments. Equity Securities Risk – As with any fund that invests in stocks, your investment will fluctuate in value, and the loss of your investment is a risk of investing. The Fund’s price per share will fluctuate due to changes in the market prices of its investments. Also, the Fund’s investments may not grow as fast as the rate of inflation and stocks tend to be more volatile than some other investments you could make, such as bonds. Growth Securities Risk – Prices of growth stocks tend to be higher in relation to their companies’ earnings and may be more sensitive to market, political and economic developments than other stocks, making their prices more volatile. An investment in the Fund may be better suited to investors who seek long-term capital growth and can tolerate fluctuations in their investment’s value. Foreign Securities Risk – The Fund’s performance will be influenced by political, social and economic factors affecting investments in foreign companies. Special risks associated with investments in foreign companies include exposure to currency fluctuations, lack of liquidity, potential for market manipulation, less developed or less efficient trading markets, limited access to reliable capital, lack of comprehensive company information, political instability, differing audit, regulatory, and legal standards and lack of financial reporting standards. Additionally, events and evolving conditions in certain markets or regions may alter the risk profile of investments tied to those markets or regions. This may cause investments tied to such markets or regions to become riskier or more volatile, even when investments in such markets or regions were perceived as comparatively stable historically. In addition, foreign companies with securities listed on U.S. exchanges may be delisted if they do not meet U.S. accounting standards and auditor oversight requirements, which may decrease the liquidity and value of the securities. Emerging Markets Risk – The Fund may invest in issuers located in emerging markets, and therefore may be exposed to the economies, industries, securities and currency markets of such countries, which may be adversely affected by protectionist trade policies, a slow U.S. economy, political and social instability, regional and global conflicts, terrorism and war, including actions that are contrary to the interests of the United States. Emerging markets are riskier than more developed markets because they tend to develop unevenly and may never fully develop. Investments in emerging markets may be considered speculative. Emerging markets are more likely to experience hyperinflation and currency devaluations, which adversely affect returns to U.S. investors. In addition, many emerging securities markets have far lower trading volumes and less liquidity than developed markets. The Fund, individually or in combination with other shareholders, may have limited rights and remedies against emerging market issuers. Frontier Markets Risk – The Fund may invest in issuers located in frontier countries. Frontier markets are those emerging markets that are considered to be among the smallest, least mature and least liquid, and as a result, may be more likely to experience inflation, political turmoil and rapid changes in economic conditions than more developed and traditional emerging markets. Investments in frontier markets may be subject to a greater risk of loss than investments in more developed and traditional emerging markets. Frontier markets often have less uniformity in accounting, auditing and financial reporting requirements, unreliable securities valuations and greater risk associated with custody of securities. Economic, political and currency risks may be more pronounced with respect to investments in frontier markets than in emerging markets. Small Cap Securities Risk – There may be greater risk in investing in companies with small market capitalizations rather than larger, more established companies owing to such factors as more limited product lines or financial resources or lack of management depth. It may also be difficult or impossible to liquidate a security position at a time and price acceptable to the Fund because of the potentially less frequent trading of stocks of smaller market capitalization. Sector Risk – The Fund may have a significant portion of its assets invested in securities of companies conducting business within a single sector, as defined by third party sources. Companies in the same sector may be similarly affected by economic, regulatory, political or market events or conditions, which may make the Fund more vulnerable to unfavorable developments in that sector than a fund that has a more diversified portfolio. Generally, the more broadly the Fund invests, the more it spreads risk and potentially reduces the risks of loss and volatility. ●Consumer Discretionary Sector Risk – The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, competition, consumers’ disposable income, consumer preferences, social trends and marketing campaigns. ●Financials Sector Risk – The Fund may have a significant portion of its assets invested in securities of financial services companies, which means the Fund may be more affected by the performance of the financials sector than a fund that is more diversified. Financial services companies are subject to extensive governmental regulation which may limit both the amounts and types of loans and other financial commitments they can make, the interest rates and fees they can charge, the scope of their activities, the prices they can charge and the amount of capital they must maintain. Certain events in the financials sector may cause an unusually high degree of volatility in the financial markets, both domestic and foreign, and cause certain financial services companies to incur large losses. ●Information Technology Sector Risk – The Fund may have a significant portion of its assets invested in securities of technology-related companies. Therefore, the Fund may be more susceptible to particular risks that may affect companies in the information technology sector and technology-related sectors than if it were invested in a wider variety of companies in unrelated sectors. At times, the performance of such companies will lag the performance of other industries or the broader market as a whole. Certain technology related companies may face special risks that their products or services may not prove to be commercially successful. Technology related companies are also strongly affected by worldwide scientific or technological developments. As a result, their products may rapidly become obsolete. Such companies are also often subject to governmental regulation and may, therefore, be adversely affected by governmental policies. These factors may lead to limited earnings and/or failing profit margins. As a result, the value of technology related companies’ securities may fall or fail to rise. Many technology related companies’ securities have historically been more volatile than other securities, especially over the short term. ●Communication Services Sector Risk – Communication services companies are particularly vulnerable to the potential obsolescence of products and services due to technological advancement and the innovation of competitors. Companies in the communication services sector may also be affected by other competitive pressures, such as pricing competition, as well as research and development costs, substantial capital requirements and government regulation. Additionally, fluctuating domestic and international demand, shifting demographics and often unpredictable changes in consumer tastes can drastically affect a communication services company’s profitability. While all companies may be susceptible to network security breaches, certain companies in the communication services sector may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses. ●Industrials Sector Risk – The Fund may have a significant portion of its assets invested in securities of companies in the industrials sector. Industrial companies are affected by supply and demand both for their specific product or service and for industrials sector products in general. Government regulation, world events, exchange rates and economic conditions, technological developments and liabilities for environmental damage and general civil liabilities will likewise affect the performance of these companies. Aerospace and defense companies, a component of the industrials sector, can be significantly affected by government spending policies because companies involved in this industry rely, to a significant extent, on U.S. and foreign government demand for their products and services. Small Number of Holdings Risk – Under normal circumstances, the Fund invests in a small number of issuers. Therefore, the Fund’s performance may be more vulnerable to changes in the market value of a single issuer and more susceptible to risks associated with a single economic, political, or regulatory occurrence than a fund that has a higher number of holdings. Cash Position Risk – At times, the Fund may hold up to 15% of its net assets in cash (and cash equivalents), which may underperform relative to equity securities.

This expense reimbursement may only be amended or terminated prior to its expiration date by agreement between the Manager and the Fund’s Board of Trustees, and will terminate automatically in the event of termination of the Investment Advisory Agreement. The Manager may recoup any fees waived or expenses reimbursed pursuant to the contract; however, the Fund will only make repayments to the Manager if such repayment does not cause the Fund’s expense ratio after the repayment is taken into account, to exceed both (i) the expense cap in place at the time such amounts were waived or reimbursed, and (ii) the Fund’s current expense cap. Such recoupment is limited to two years from the date the amount is initially waived or reimbursed. The Fund and Fred Alger Management, LLC (the “Manager”) have adopted fee breakpoints for the Fund. The advisory fee for assets up to $1 billion is .71%, and for assets in excess of $1 billion is .65%. The actual rate paid as a percentage of average daily net assets for the year ended October 31, 2025 was .71%.
