| 1 | During the fiscal year ended October 31, 2022, the Fund paid amounts to American Beacon Advisors, Inc. (the "Manager") that were previously waived and/or reimbursed by the Manager under a contractual fee waiver/expense reimbursement agreement for the Fund's R5 Class shares in the amount of 0.01%. |

| | |
|:---|:---|
| 2 | The Manager has contractually agreed to waive fees and/or reimburse expenses of the Fund's R5 Class shares through February 29, 2024, to the extent that Total Annual Fund Operating Expenses exceed 0.89% for the R5 Class (excluding taxes, interest, brokerage commissions, acquired fund fees and expenses, securities lending fees, expenses associated with securities sold short, litigation, and other extraordinary expenses). The contractual expense reimbursement can be changed or terminated only in the discretion and with the approval of a majority of the Fund's Board of Trustees (the "Board"). The Manager will itself waive fees and/or reimburse expenses of the Fund to maintain the contractual expense ratio caps for each applicable class of shares or make arrangements with other service providers to do so. The Manager may also, from time to time, voluntarily waive fees and/or reimburse expenses of the Fund. The Manager can be reimbursed by the Fund for any contractual or voluntary fee waivers or expense reimbursements if reimbursement to the Manager (a) occurs within three years from the date of the Manager's waiver/reimbursement and (b) does not cause the Total Annual Fund Operating Expenses of a class to exceed the lesser of the contractual percentage limit in effect at the time of the waiver/reimbursement or the time of the recoupment. |

**Example**

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual 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. The Example also assumes 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, whether you redeem or hold your shares, your costs would be:

|  **Share Class** | **1 Year** | **3 Years** | **5 Years** | **10 Years** |
| Y | $97 | $303 | $525 | $1166 |
| R5 | $91 | $286 | $497 | $1107 |
| Investor | $120 | $375 | $649 | $1432 |

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 21% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, at least 80% of the Fund's net assets (plus the amount of any borrowings for investment purposes) are invested in equity securities of small market capitalization companies that are economically tied to countries outside of the United States, including developed and emerging market countries. The Fund considers a company to be economically tied to a country outside of the United States if the company is included in the MSCI<sup>®</sup> ACWI ex USA Small Cap Index or is otherwise classified by MSCI as a non-United States company. The Fund may also consider other companies to be economically tied to a country outside of the United States if the sub-advisor determines that

EAM030123

**American Beacon EAM International Small Cap Fund** - Summary Prospectus**1**

------

■ the company's security is primarily listed for trading in a non-United States market;

■ the company is headquartered in a non-United States country; or

■ the company has at least half of its assets or derives at least half of its revenues outside the United States.

These companies have market capitalizations within the market capitalization range of the companies in the MSCI ACWI ex USA Small Cap Index at the time of investment. The market capitalization range of the MSCI ACWI ex USA Small Cap Index was $2.5 million to $8.2 billion as of November 30, 2022. The Fund may hold smaller companies considered micro-capitalization companies, as well as medium-capitalization companies. The Fund invests principally in equity securities, which may include common stocks, depositary receipts and U.S. dollar-denominated foreign stocks traded on U.S. exchanges. The Fund's investments in equity securities may be denominated in foreign currencies, and the Fund may invest directly in foreign currencies.

The investment process of the Fund's sub-advisor is based on bottom-up analysis of companies rather than top-down country or sector allocation. The sub-advisor's process is intended to add long-term value primarily through stock selection. The Fund may have significant exposure to Japanese and European companies. However, as the composition of the Fund's portfolio changes over time, the Fund's exposure to Japan and Europe may be lower at a future date, and the Fund's exposure to other countries or regions may be higher.

The sub-advisor seeks to generate returns by harnessing the power of the momentum premium, which is the principle that companies that have outperformed in the recent past will continue to outperform for a period of time. The sub-advisor seeks to exploit behavioral biases around change, which cause investors to underreact to new information. The sub-advisor believes these underreactions to new information lead to opportunities to invest in companies with improving or accelerating financial performance that is expected to continue, otherwise known as momentum. The sub-advisor's disciplined "Informed Momentum" approach to investing combines stock selection, tailored risk management, and efficient implementation to seek to harness the momentum premium to generate returns. The stocks of companies held by the Fund may exhibit characteristics of both value stocks and growth stocks during the time they are held by the Fund. The Fund holds approximately 100-150 investments.

The Fund may also invest cash balances in other investment companies, including a government money market fund advised by the Manager, with respect to which the Manager also receives a management fee. The Fund may seek to earn additional income by lending its securities to certain qualified broker-dealers and institutions on a short-term or long-term basis.

The Fund may engage in active and frequent trading of portfolio securities to achieve its principal investment strategies.

Principal Risks

There is no assurance that the Fund will achieve its investment objective and you could lose part or all of your investment in the Fund. The Fund is not designed for investors who need an assured level of current income and is intended to be a long-term investment. The Fund is not a complete investment program and may not be appropriate for all investors. Investors should carefully consider their own investment goals and risk tolerance before investing in the Fund. The principal risks of investing in the Fund listed below are presented in alphabetical order and not in order of importance or potential exposure. Among other matters, this presentation is intended to facilitate your ability to find particular risks and compare them with the risks of other funds. Each risk summarized below is considered a "principal risk" of investing in the Fund, regardless of the order in which it appears.

**Currency Risk**<br>The Fund may have exposure to foreign currencies by using various instruments. Foreign currencies may fluctuate significantly over short periods of time, may be affected unpredictably by intervention, or the failure to intervene, of the U.S. or foreign governments or central banks, and may be affected by currency controls or political developments in the U.S. or abroad. Foreign currencies may also decline in value relative to the U.S. dollar and other currencies and thereby affect the Fund's investments.

**Cybersecurity and Operational Risk**<br>Operational risks arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents may negatively impact the Fund and its service providers as well as the ability of shareholders to transact with the Fund, and result in financial losses. Cybersecurity incidents may allow an unauthorized party to gain access to Fund assets, shareholder data, or proprietary information, or cause the Fund or its service providers, as well as securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Fund or its service providers to identify all of the operational risks that may affect the Fund or to develop processes and controls to completely eliminate or mitigate their occurrence or effects. The Fund cannot control the cybersecurity plans and systems of its service providers, its counterparties or the issuers of securities in which the Fund invests. Most issuers in which the Fund invests are heavily dependent on computers for data storage and operations, and require ready access to the internet to conduct their business. Thus, cybersecurity incidents could also affect issuers of securities in which the Fund invests, leading to significant loss of value.

**Emerging Markets Risk**<br>When investing in emerging markets, the risks of investing in foreign securities are heightened. Emerging markets are generally smaller, less developed, less liquid and more volatile than the securities markets of the U.S. and other developed markets. There are also risks of: greater political or economic uncertainties; an economy's dependence on revenues from particular commodities or on international aid or development assistance; currency transfer restrictions; a limited number of potential buyers for such securities resulting in increased volatility and limited liquidity for emerging market securities; trading suspensions and other restrictions on investment; delays and disruptions in securities clearing and settlement procedures; and significant limitations on investor rights and recourse. The governments of emerging market countries may also be more unstable and more likely to impose capital controls, nationalize a company or industry, place restrictions on foreign ownership and on withdrawing sale proceeds of securities from the country, intervene in the financial markets, and/or impose burdensome taxes that could adversely affect security prices. In addition, there may be less publicly available information about issuers in emerging markets than would be available about issuers in more developed capital markets, and such issuers may not be subject to accounting, auditing, financial reporting and recordkeeping standards and requirements comparable to those to which U.S. companies are subject.

**Equity Investments Risk**<br>Equity securities are subject to investment risk, issuer risk and market risk. In general, the values of stocks and other equity securities fluctuate, and sometimes widely fluctuate, in response to changes in a company's financial condition as well as general market, economic and political conditions and other factors. The Fund may experience a significant or complete loss on its investment in an equity security. In addition, stock prices may be particularly sensitive to rising interest rates, which increase borrowing costs and the costs of capital. The Fund may invest in the following equity securities, which may expose the Fund to the following additional risks:

■ Common Stock Risk. The value of a company's common stock may fall as a result of factors affecting the company, companies in the same industry or sector, or the financial markets overall. Common stock generally is subordinate to preferred stock upon the liquidation or bankruptcy of the issuing company.

■ Depositary Receipts and/or U.S. Dollar-Denominated Foreign Stocks Traded on U.S. Exchanges Risk. Depositary receipts and U.S. dollar-denominated foreign stocks traded on U.S. exchanges are subject to certain of the risks associated with investing directly in foreign securities, including, but not limited to, currency exchange rate fluctuations, political and financial instability in the home country of a particular depositary receipt or foreign stock, less liquidity, more volatility, less government regulation and supervision and delays in transaction settlement.

**2** **American Beacon EAM International Small Cap Fund** - Summary Prospectus

------

**Foreign Investing Risk**<br>Non-U.S. investments carry potential risks not associated with U.S. investments. Such risks include, but are not limited to: (1) currency exchange rate fluctuations, (2) political and financial instability, (3) less liquidity, (4) lack of uniform accounting, auditing and financial reporting standards, (5) greater volatility, (6) different government regulation and supervision of foreign stock exchanges, brokers and listed companies, and (7) delays or failures in transaction payment and settlement in some foreign markets. The Fund's investment in a foreign issuer may subject the Fund to regulatory, political, currency, security, economic and other risks associated with that country. Global economic and financial markets have become increasingly interconnected and conditions (including recent volatility, terrorism, war and political instability) and events (including natural disasters) in one country, region or financial market may adversely impact issuers in a different country, region or financial market.

**Geographic Concentration Risk**<br>From time to time, based on market or economic conditions, the Fund may invest a significant portion of its assets in the securities of issuers located in, or with significant economic ties to, a single country or geographic region, which could increase the risk that economic, political, business, regulatory, diplomatic, social and environmental conditions in that particular country or geographic region may have a significant impact on the Fund's performance. Investing in such a manner could cause the Fund's performance to be more volatile than the performance of more geographically diverse funds.

■ European Securities Risk. The Fund's performance may be affected by political, social and economic conditions in Europe, such as growth of economic output (the gross national product), the rate of inflation, the rate at which capital is reinvested into European economies, the success of governmental actions to reduce budget deficits, the resource self-sufficiency of European countries and conflict between European countries. The European financial markets have experienced and may continue to experience volatility and adverse trends due to concerns relating to economic downturns; rising government debt levels and the possible default on government debt; national unemployment in several European countries; and, most recently, the COVID-19 pandemic and the Russian invasion of Ukraine. These events have adversely affected the exchange rate of the euro and may continue to significantly affect European countries. Responses to financial problems by European governments, central banks, and others, including austerity measures and other reforms, may not produce the desired results, may result in social unrest and may limit future growth and economic recovery or may have unintended consequences. In addition, one or more countries may abandon the euro and/or withdraw from the European Union ("EU"). The impact of these actions, especially if they occur in a disorderly fashion, could be significant and far-reaching. <br> Many EU nations are susceptible to economic risks associated with high levels of debt, and a default or debt restricting by any European country could adversely impact holders of that country's debt and sellers of credit default swaps linked to that country's creditworthiness, which may be located in other countries. Such a default or debt restructuring could affect exposures to other EU countries and their companies as well. In addition, issuers have faced difficulties obtaining credit or refinancing existing obligations, and financial markets have experienced extreme volatility and declines in asset values and liquidity. Russia's war with Ukraine has negatively impacted European economic activity. The effects on the economies of European countries of the Russia/Ukraine war and Russia's response to sanctions imposed by the U.S. and other countries are impossible to predict, but have been and could continue to be significant. For example, exports in Eastern Europe have been disrupted for certain key commodities, pushing commodity prices to record highs, and energy prices in Europe have increased significantly.

■ Japan Investment Risk. The Japanese economy is heavily dependent upon international trade and may be adversely affected by trade tariffs, other protectionist measures, competition from emerging economies, changes in international trade agreements, the economic conditions of its trading partners, the strength of the yen, and regional and global conflicts. Political tensions between Japan and its trading partners could adversely affect the economy, especially the export sector, and destabilize the region as a whole. The domestic Japanese economy faces several concerns, including large government deficits and a shrinking workforce. The Japanese Government's tax and fiscal policies may have negative impacts on the Japanese economy. Japan is also heavily dependent on oil and other commodity imports, and higher commodity prices could therefore have a negative impact on the Japanese economy. Currency fluctuations, which have been significant at times, can have a considerable impact on exports and the overall Japanese economy. Japan has, in the past, intervened in the currency markets to attempt to maintain or reduce the value of the yen. Japanese intervention in the currency markets could cause the value of the yen to fluctuate sharply and unpredictably and could cause losses to investors. Natural disasters such as earthquakes, volcanoes, typhoons or tsunamis, could occur in Japan and surrounding areas and may have a significant impact on the business operations of Japanese companies in the affected regions and Japan's economy. These and other factors could have a negative impact on the Fund's performance and increase the volatility of an investment in the Fund.

**Growth Companies Risk**<br>Growth companies are expected to increase their earnings at a certain rate. When these expectations are not met or decrease, the prices of these stocks may decline, sometimes sharply, even if earnings showed an absolute increase. The Fund's investments in growth companies may be more sensitive to company earnings and more volatile than the market in general primarily because their stock prices are based heavily on future expectations. If an assessment of the prospects for a company's growth is incorrect, then the price of the company's stock may fall or not approach the value placed on it. Growth company stocks may also lack the dividend yield that can cushion stock price declines in market downturns.

**High Portfolio Turnover** **Risk**<br>Portfolio turnover is a measure of the Fund's trading activity over a one-year period. A portfolio turnover rate of 100% would indicate that the Fund sold and replaced the entire value of its securities holdings during the period. The Fund may engage in active and frequent trading and may have a high portfolio turnover rate, which could increase the Fund's transaction costs, have a negative impact on performance, and generate higher capital gain distributions to shareholders than if the Fund had a lower portfolio turnover rate.

**Investment Risk**<br>An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. When you sell your shares of the Fund, they could be worth less than what you paid for them. Therefore, you may lose money by investing in the Fund.

**Issuer Risk**<br>The value of, and/or the return generated by, a security may decline for a number of reasons that directly relate to the issuer, such as management performance, financial leverage and reduced demand for the issuer's goods or services, as well as the historical and prospective earnings of the issuer and the value of its assets.

**Market Risk**<br>The Fund is subject to the risk that the securities markets will move down, sometimes rapidly and unpredictably, based on overall economic conditions and other factors, which may negatively affect the Fund's performance. Equity securities generally have greater price volatility than fixed-income securities, although under certain market conditions fixed-income securities may have comparable or greater price volatility. During a general downturn in the securities markets, multiple assets may decline in value simultaneously. Prices in many financial markets have increased significantly over the last decade, but there have also been periods of adverse market and financial developments and cyclical change during that timeframe, which have resulted in unusually high levels of volatility in domestic and foreign financial markets that has caused losses for investors and may occur again in the future. The value of a security may decline due to adverse issuer-specific conditions, general market conditions unrelated to a particular issuer, such as changes in interest or inflation rates, or factors that affect a particular industry or industries. Changes in the financial condition of a single issuer or market segment also can impact the market as a whole. Geopolitical and other events, including war, terrorism, economic uncertainty, trade disputes, pandemics, public health crises, natural disasters and related events have led, and in the future may continue to lead, to instability in world economies and markets generally and reduced liquidity in equity, credit and fixed-income markets, which may disrupt economies and markets and adversely affect the value of your investment. Changes in value may be temporary or may last for extended periods.

**American Beacon EAM International Small Cap Fund** - Summary Prospectus**3**

------

Policy changes by the U.S. government and/or Federal Reserve and political events within the U.S. and abroad, such as changes in the U.S. presidential administration and Congress, the U.S. government's inability at times to agree on a long-term budget and deficit reduction plan, the threat of a federal government shutdown and threats not to increase the federal government's debt limit which could result in a default on the government's obligations, may affect investor and consumer confidence and may adversely impact financial markets and the broader economy, perhaps suddenly and to a significant degree.

Markets and market participants are increasingly reliant upon both publicly available and proprietary information data systems. Data imprecision, software or other technology malfunctions, programming inaccuracies, unauthorized use or access, and similar circumstances may impair the performance of these systems and may have an adverse impact upon a single issuer, a group of issuers, or the market at large.

The financial markets generally move in cycles, with periods of rising prices followed by periods of declining prices. The value of your investment may reflect these fluctuations.

■ Recent Market Events Risk. Both U.S. and international markets have experienced significant volatility in recent months and years. As a result of such volatility, investment returns may fluctuate significantly. Moreover, the risks discussed herein associated with an investment in the Fund may be increased. An outbreak of infectious respiratory illness caused by a novel coronavirus, known as COVID-19, was first detected in late 2019 and has subsequently spread globally. The transmission of various variants of COVID-19, and efforts to contain their spread, have resulted, and may continue to result, in significant disruptions to business operations, travel restrictions and closed borders, and lower consumer demand, as well as general concern and uncertainty that has negatively affected the global economy. Any resurgence of COVID-19, a variant or other significant viruses could negatively impact the Fund and adversely impact the economies of many nations, individual companies and the global securities and commodities markets, including their liquidity, in ways that cannot necessarily be foreseen at the present time. <br> Although interest rates were unusually low in recent years in the U.S. and abroad, in 2022, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates may continue to increase, or the timing, frequency or magnitude of any such increases. Additionally, various economic and political factors could cause the Federal Reserve or another foreign central bank to change their approach in the future and such actions may result in an economic slowdown in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets. Additionally, high public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty. <br> Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth; risks associated with a trade agreement between the United Kingdom and the European Union; the risks associated with ongoing trade negotiations with China; the possibility of changes to some international trade agreements; tensions, war, or open conflict between nations, such as between Russia and Ukraine or in eastern Asia; political or economic dysfunction within some nations, including major producers of oil; and dramatic changes in commodity and currency prices could affect the economies of many nations, including the United States, in ways that cannot necessarily be foreseen at the present time. Russia's military invasion of Ukraine beginning in February 2022, the responses and sanctions by the United States and other countries, and the potential for wider conflict have had, and could continue to have, severe adverse effects on the performance and liquidity of global markets, and negatively affect the value of the Fund's investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted. The recent strength of the U.S. dollar could decrease foreign demand for U.S. assets, which may negatively impact certain issuers and/or industries. <br> Economists and others have expressed increasing concern about the potential effects of global climate change on property and security values. Certain issuers, industries and regions may be adversely affected by the impacts of climate change, including on the demand for and the development of goods and services and related production costs, and the impacts of legislation, regulation and international accords related to climate change, as well as any indirect consequences of regulation or business trends driven by climate change.

**Market Timing Risk**<br>The Fund is subject to the risk of market timing activities by investors due to the nature of the Fund's investments, which requires the Fund, in certain instances, to fair value certain of its investments. Some investors may engage in frequent short-term trading in the Fund to take advantage of any price differentials that may be reflected in the net asset value ("NAV") of the Fund's shares. Frequent trading by Fund shareholders poses risks to other shareholders in the Fund, including (i) the dilution of the Fund's NAV, (ii) an increase in the Fund's expenses, and (iii) interference with the ability to execute efficient investment strategies.

**Micro-Capitalization Companies Risk**<br>Micro-capitalization companies are subject to substantially greater risks of loss and price fluctuations, sometimes rapidly and unpredictably, because their earnings and revenues tend to be less predictable. Since micro-capitalization companies may not have an operating history, product lines, or financial resources, their share prices tend to be more volatile and their markets less liquid than companies with larger market capitalizations, and they can be sensitive to changes in overall economic conditions, interest rates, borrowing costs and earnings. The shares of micro-capitalization companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the future ability to sell these securities.

**Mid-Capitalization Companies Risk**<br>Investing in the securities of mid-capitalization companies involves greater risk and the possibility of greater price volatility, which at times can be rapid and unpredictable, than investing in larger-capitalization and more established companies. Since mid-capitalization companies may have narrower commercial markets and more limited operating history, product lines, and managerial and financial resources than larger, more established companies, the securities of these companies may lack sufficient market liquidity, and they can be particularly sensitive to changes in overall economic conditions, interest rates, borrowing costs and earnings.

**Other Investment Companies Risk**<br>To the extent that the Fund invests in shares of other registered investment companies, the Fund will indirectly bear the fees and expenses charged by those investment companies in addition to the Fund's direct fees and expenses. To the extent the Fund invests in other investment companies that invest in equity securities, fixed-income securities and/or foreign securities, or that track an index, the Fund is subject to the risks associated with the underlying investments held by the investment company or the index fluctuations to which the investment company is subject. The Fund will be subject to the risks associated with investments in those companies, including but not limited to the following:

■ Government Money Market Funds Risk. Investments in government money market funds are subject to interest rate risk, credit risk, and market risk. Interest rate risk is the risk that rising interest rates could cause the value of such an investment to decline. Credit risk is the risk that the issuer, guarantor or insurer of an obligation, or the counterparty to a transaction, may fail or become less able or unwilling, to make timely payment of interest or principal or otherwise honor its obligations, or that it may default completely.

**Redemption Risk**<br>The Fund may experience periods of high levels of redemptions that could cause the Fund to sell assets at inopportune times or at a loss or depressed value. Heavy redemptions could hurt the Fund's performance. The sale of assets to meet redemption requests may create net capital gains, which could cause the Fund to have to distribute substantial capital gains. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of

**4** **American Beacon EAM International Small Cap Fund** - Summary Prospectus

investments in the Fund. In addition, redemption risk is heightened during periods of declining or illiquid markets. During periods of heavy redemptions, the Fund may borrow funds through the interfund credit facility or from a bank line of credit, which may increase costs. The sale of assets to meet redemption requests may create net capital gains or losses, which could cause the Fund to have to distribute substantial capital gains.

**Securities Lending Risk**<br>To the extent the Fund lends its securities, it may be subject to the following risks: (i) the securities in which the Fund reinvests cash collateral may decrease in value, causing the Fund to incur a loss, or may not perform sufficiently to cover the Fund's payment to the borrower of a pre-negotiated fee or "rebate" for the use of that cash collateral in connection with the loan; (ii) non-cash collateral may decline in value, resulting in the Fund becoming under-secured; (iii) delays may occur in the recovery of loaned securities from borrowers, which could result in the Fund being unable to vote proxies or settle transactions or cause the Fund to incur increased costs; and (iv) if the borrower becomes subject to insolvency or similar proceedings, the Fund could incur delays in its ability to enforce its rights in its collateral.

**Securities Selection Risk**<br>Securities selected for the Fund may not perform to expectations. This could result in the Fund's underperformance compared to its performance index(es), or other funds with similar investment objectives or strategies.

**Small-Capitalization Companies Risk**<br>Investing in the securities of small-capitalization companies involves greater risk and the possibility of greater price volatility, which at times can be rapid and unpredictable, than investing in larger-capitalization and more established companies. Since small-capitalization companies may have narrower commercial markets, and more limited operating history, product lines, and managerial and financial resources than larger, more established companies, the securities of these companies may lack sufficient market liquidity and they can be particularly sensitive to changes in overall economic conditions, interest rates, borrowing costs and earnings.

**Valuation Risk**<br>Certain of the Fund's assets may be valued at a price different from the price at which they can be sold. This risk may be especially pronounced for investments that are illiquid or may become illiquid, or securities that trade in relatively thin markets and/or markets that experience extreme volatility. The valuation of the Fund's investments in an accurate and timely manner may be impacted by technological issues and/or errors by third party service providers, such as pricing services or accounting agents.

**Value Stocks Risk**<br>Value stocks are subject to the risk that their intrinsic or full value may never be realized by the market, that a stock judged to be undervalued may be appropriately priced, or that their prices may decline. Although value stocks tend to be inexpensive relative to their earnings, they can continue to be inexpensive for long periods of time. The Fund's investments in value stocks seek to limit potential downside price risk over time; however, value stock prices still may decline substantially. In addition, the Fund may produce more modest gains as a trade-off for this potentially lower risk. The Fund's investment in value stocks could cause the Fund to underperform funds that use a growth or non-value approach to investing or have a broader investment style.

Fund Performance

The bar chart and table below provide an indication of risk by showing changes in the Fund's performance over time. The bar chart shows how the Fund's performance has varied from year to year. The table shows how the Fund's average annual total returns compare to a broad-based market index for the periods indicated. Effective January 21, 2023, a new sub-advisor began managing the Fund and the Fund implemented a policy to invest at least 80% of its net assets (plus the amount of borrowings for investment purposes) in equity securities of small market capitalization companies that are economically tied to countries outside of the United States, including developed and emerging market countries. Performance through January 20, 2023 reflects the Fund's performance under the management and strategy of its prior sub-advisor.

Each of the Fund's share classes commenced operations on January 22, 2019. The Fund acquired the assets and liabilities of The Tocqueville International Value Fund, a series of The Tocqueville Trust, in a reorganization that closed upon the close of business on January 18, 2019. In connection with that reorganization, the Investor Class shares of the Fund have adopted the performance history and financial statements of the Fund's predecessor. In the bar chart and table below, the performance of the Fund's Investor Class shares for periods prior to January 22, 2019 reflects the returns of the shares of the Fund's predecessor. In the table below, the performance of the Y Class and R5 Class shares for periods prior to January 22, 2019 reflects the returns of the shares of the Fund's predecessor. The Y Class and R5 Class shares would have had similar annual returns to the shares of the Fund's predecessor because the shares of each class represent investments in the same portfolio securities. However, the shares of the Fund's predecessor had different expenses than the Y Class and R5 Class shares, which would affect performance. To the extent that the Fund's predecessor had lower expenses than a newer share class, the performance of the Fund's predecessor would likely have been higher than the newer share class would have realized during the same period. The Y Class and R5 Class performance shown in the table below has not been adjusted for differences in operating expenses between those share classes and the shares of the predecessor fund. You may obtain updated performance information on the Fund's website at www.americanbeaconfunds.com. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

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 income taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. The return after taxes on distributions and sale of Fund shares may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period. If you are a tax-exempt entity or hold your Fund shares through a tax-deferred arrangement, such as an individual retirement account ("IRA") or a 401(k) plan, the after-tax returns do not apply to your situation. After-tax returns are shown only for Investor Class shares of the Fund; after-tax returns for other share classes will vary.
