1	A contingent deferred sales charge (‘‘CDSC’’) of 0.50% will be charged on certain purchases of $1,000,000 or more of A Class shares that are redeemed in whole or part within 18 months of purchase.

2	Other Expenses and Acquired Fund Fees and Expenses for the A Class and C Class shares are based on estimated expenses for the current fiscal year.

3	The Total Annual Fund Operating Expenses do not correlate to the ratio of expenses to average net assets provided in the Fund’s Financial Highlights table, which reflects the operating expenses of the Fund and does not include Acquired Fund Fees and Expenses.

American Beacon Advisors, Inc. (the “Manager”) has contractually agreed to waive fees and/or reimburse expenses of the Fund’s A Class, C Class, Y Class, R5 Class, and Investor Class shares, as applicable, through May 31, 2022 to the extent that Total Annual Fund Operating Expenses exceed 1.45% for the A Class, 2.20% for the C Class, 1.25% for the Y Class, 1.15% for the R5 Class, and 1.53% for the Investor 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 (“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

CCEM052821

American Beacon Continuous Capital Emerging Markets Fund - Summary Prospectus1

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.

During the fiscal year ended January 31, 2021, 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 0.08% for the R5 Class shares.

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, except that this Example reflects the fee waiver/expense reimbursement arrangement for each share class through May 31, 2022. Although your actual costs may be higher or lower, based on these assumptions your costs would be:


Share Class	1 Year	3 Years	5 Years	10 Years
A	$ 715	$ 1,798	$ 2,868	$ 5,490
C	$ 324	$ 1,508	$ 2,758	$ 5,741
Y	$ 128	$ 708	$ 1,314	$ 2,953
R5	$ 118	$ 696	$ 1,301	$ 2,937
Investor	$ 157	$ 843	$ 1,553	$ 3,441

Assuming no redemption of shares:


Share Class	1 Year	3 Years	5 Years	10 Years
C	$ 224	$ 1,508	$ 2,758	$ 5,741

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 94% 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 securities of companies economically tied to emerging market countries at the time of investment. A company is generally regarded as being economically tied to an emerging market country if it:

■	is primarily listed on the trading market of an emerging market country;

■	is headquartered in an emerging market country;

■	is domiciled in an emerging market country; or

■	derives 50% or more of its revenue from, or has 50% or more of its assets in, an emerging market country.

An emerging market country is one that:

■	has an emerging stock market as defined by the International Finance Corporation;

■	has a low- to middle-income economy according to the World Bank;

■	is included in the IFC Investable Index or the Morgan Stanley Capital International Emerging Markets Index; or

■	has a per-capita gross national product of $10,000 or less.

The Fund’s investment sub-advisor, Continuous Capital, LLC (“Sub-Advisor”), seeks to achieve the Fund’s investment objective by applying a fundamental research philosophy and approach to identify companies that trade at attractive valuations and are of high quality. When selecting stocks for the Fund, the Sub-Advisor considers characteristics, such as:

■	price-to-earnings ratio – share price relative to earnings-per-share,

■	enterprise value-to-EBITDA (earnings before interest, taxes, depreciation and amortization) ratio – a company’s enterprise value relative to its earnings before interest, tax, depreciation and amortization,

■	dividend yield – ratio of dividends-per-share to the stock price,

■	dividend growth – the year over year change in dividends per share,

■	return on invested capital – ratio of a company’s earnings to its equity and debt, and

■	return on equity – ratio of a company’s earnings to its equity.

The Sub-Advisor also utilizes a combination of qualitative and fundamental research considerations to select securities for the Fund. These considerations include evaluating the efficacy of company management’s historical capital allocation, dividend, and share repurchase policies. The Sub-Advisor seeks to diversify investments across industries and countries.

Although the Fund seeks diversification across sectors and industries, from time to time, based on portfolio positioning, the Fund may have significant positions (e.g., 25% or more of the Fund’s net assets) in particular sectors. However, as the sector composition of the Fund’s portfolio changes over time, the Fund’s exposure to a sector may be lower at a future date, and the Fund’s exposure to other market sectors may be higher. The Fund may invest in companies of all market capitalizations.

The Fund’s equity investments may include common stocks, depositary receipts including both American Depositary Receipts (“ADRs”) and Global Depositary Receipts (“GDRs”), U.S. dollar-denominated foreign stocks traded on U.S. exchanges, preferred stocks, and real estate investment trusts (“REITs”). The Fund may, at times, invest significantly in shares of Chinese companies listed on mainland China and Hong Kong exchanges as well as in ADRs. However, as the country allocation of the Fund’s portfolio changes over time, the Fund’s exposure to Chinese companies may be lower at a future date, and the Fund’s exposure to other countries may be higher. The Fund may have exposure to foreign currencies by making direct investments in non-U.S. currencies, engaging in foreign currency transactions on a spot (cash) basis, or investing in securities denominated in non-U.S. currencies.

The Fund may also invest cash balances in other investment companies, including government money market funds, and exchange-traded funds (“ETFs”).

In pursuing its investment strategies, the Fund typically engages in active trading strategies that result in high portfolio turnover.

The Fund may lend its securities to broker-dealers and other institutions to earn additional income.

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
The Fund may have exposure to foreign currencies by using various instruments described below. 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 in non-U.S. currencies or in securities that trade in, and receive revenues in, non-U.S. currencies. The Fund may gain exposure to foreign currencies because of its investments in one or more of the following:

■	Non-U.S. currencies

■	Foreign currency transactions on a spot (cash) basis

■	Securities denominated in non-U.S. currencies

Cybersecurity and Operational Risk
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. 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. 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. 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.

Dividend Risk
An issuer of stock held by the Fund may choose not to declare a dividend or the dividend rate might not remain at current levels or increase over time. Dividend paying stocks might not experience the same level of earnings growth or capital appreciation as non-dividend paying stocks. Securities that pay dividends may be sensitive to changes in interest rates and, as interest rates rise or fall, the prices of such securities may fall.

Emerging Markets Risk
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 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
Equity securities are subject to investment risk and market risk. 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 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.

■

Preferred Stock Risk. Preferred stocks are sensitive to movements in interest rates. Preferred stocks may be less liquid than common stocks and, unlike common stocks, participation in the growth of an issuer may be limited. Distributions on preferred stocks generally are payable at the discretion of an issuer and after required payments to bond holders. In certain situations, an issuer may call or redeem its preferred stock or convert it to common stock. The market prices of preferred stocks are generally more sensitive to actual or perceived changes in the issuer’s financial condition or prospects than are the prices of debt securities.

■

Real Estate Investment Trusts (“REITs”) Risk. Investments in REITs are subject to the risks associated with investing in the real estate industry, including, among other risks: adverse developments affecting the real estate industry; declines in real property values; changes in interest rates; defaults by mortgagors or other borrowers and tenants; lack of availability of mortgage funds or financing; extended vacancies of properties, especially during economic downturns; casualty or condemnation losses; and governmental actions, such as changes to tax laws, zoning regulations or environmental regulations. REITs also are dependent upon the skills of their managers and are subject to heavy cash flow dependency or self-liquidation. Regardless of where a REIT is organized or traded, its performance may be affected significantly by events in the region where its properties are located. Domestic REITs could be adversely affected by failure to qualify for tax-free “pass-through” of distributed net income and net realized gains under the Internal Revenue Code of 1986, as amended (“Internal Revenue Code”), or to maintain their exemption from registration under the Investment Company Act of 1940, as amended (“Investment Company Act”). REITs typically incur fees that are separate from those incurred by the Fund. Accordingly, the Fund’s investment in REITs will result in the layering of expenses such that shareholders will indirectly bear a proportionate share of the REITs’ operating expenses, in addition to paying Fund expenses. The value of REIT common stock may decline when interest rates rise. REITs tend to be small- to mid-capitalization securities and, as such, are subject to the risks of investing in small- to mid-capitalization securities.

American Beacon Continuous Capital Emerging Markets Fund - Summary Prospectus3

Foreign Investing Risk
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 in transaction 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 are becoming increasingly interconnected and conditions (including recent volatility and 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
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.

■

China Investment Risk. Investing in securities of Chinese issuers, including A-Shares, involves certain risks and considerations not typically associated with investing in securities of U.S. issuers, including, among others, more frequent trading suspensions and government interventions (including by nationalization of assets), currency exchange rate fluctuations or blockages, limits on the use of brokers and on foreign ownership, different financial reporting standards, higher dependence on exports and international trade, potential for increased trade tariffs, embargoes and other trade limitations, and custody risks associated with programs used to access Chinese securities. Significant portions of the Chinese securities markets may become rapidly illiquid, as Chinese issuers have the ability to suspend the trading of their equity securities, and have shown a willingness to exercise that option in response to market volatility and other events.

High Portfolio Turnover Risk
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
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.

Large-Capitalization Companies Risk
The securities of large market capitalization companies may underperform other segments of the market because such companies may be less responsive to competitive challenges and opportunities. Many larger-capitalization companies also may be unable to attain the high growth rates of successful smaller companies, especially during periods of economic expansion.

Liquidity Risk
The Fund is susceptible to the risk that certain investments held by the Fund may have limited marketability, be subject to restrictions on sale, be difficult or impossible to purchase or sell at favorable times or prices, or become less liquid in response to market developments or adverse credit events that may affect issuers or guarantors of a security. An inability to sell a portfolio position can adversely affect the Fund’s value or prevent the Fund from being able to take advantage of other investment opportunities. The Fund could lose money if it is unable to dispose of an investment at a time that is most beneficial to the Fund. The Fund may be required to dispose of investments at unfavorable times or prices to satisfy obligations, which may result in losses or may be costly to the Fund. For example, liquidity risk may be magnified in rising interest rate environments in the event of higher than normal redemption rates. Unexpected redemptions may force the Fund to sell certain investments at unfavorable prices to meet redemption requests or other cash needs. Judgment plays a greater role in pricing illiquid investments than in investments with more active markets.

Market Risk
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, 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. Policy changes by the U.S. government and/or Federal Reserve and political events within the U.S. and abroad, including changes in the U.S. presidential administration and Congress, 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. An outbreak of infectious respiratory illness caused by a novel coronavirus, known as COVID-19, was first detected in December 2019 and has subsequently spread globally. The transmission of COVID-19 and efforts to contain its spread have resulted, and may continue to result, in significant disruptions to business operations, widespread business closures and layoffs, travel restrictions and closed borders, prolonged quarantines and stay-at-home orders, disruption of and delays in healthcare service preparation and delivery, service and event changes, and lower consumer demand, as well as general concern and uncertainty that has negatively affected the global economy. The impact of the COVID-19 pandemic may last for an extended period of time and may result in a sustained economic downturn or recession. The U.S. Federal Reserve and the U.S. federal government have taken numerous measures to address the economic impact of the COVID-19 pandemic and stimulate the U.S. economy. The ultimate effects of these and other efforts that may be taken may not be known for some time.

The Federal Reserve has spent hundreds of billions of dollars to keep credit flowing through short-term money markets and has signaled that it plans to maintain its interventions at an elevated level. Amid these ongoing efforts, concerns about the markets’ dependence on the Federal Reserve’s provision of liquidity have grown. Future legislative, regulatory and policy changes may result in more restrictions on international trade, less stringent prudential regulation of certain players in the financial markets, and significant new investments in infrastructure and national defense. High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty. A rise in protectionist trade policies, slowing global economic growth, risks

4American Beacon Continuous Capital Emerging Markets Fund - Summary Prospectus

associated with the United Kingdom’s departure from the European Union on December 31, 2020, commonly referred to as “Brexit,” and 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 or open conflict between nations, or political or economic dysfunction within some nations that are major producers of oil could affect the economies of many nations, including the United States, in ways that cannot necessarily be foreseen at the present time.

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
Because of specific types of securities in which the Fund may invest, it could be subject to the risk of market timing activities by shareholders. In addition, because the Fund invests in foreign securities, it is particularly subject to the risk of market timing activities. 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 portfolio manager’s ability to execute efficient investment strategies. While the Manager monitors trading in the Fund, there is no guarantee that it can detect all market timing activities.

Mid-Capitalization Companies Risk
Investing in the securities of mid-capitalization companies involves greater risk and the possibility of greater price volatility 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 expected changes in interest rates, borrowing costs and earnings.

Other Investment Companies Risk
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:

■

ETFs. Because exchange-traded funds (“ETFs”) are listed on an exchange, they may be subject to trading halts, may trade at a premium or discount to their net asset value (“NAV”) and may not be liquid. An ETF that tracks an index may not precisely replicate the returns of that index, and an actively-managed ETF’s performance will reflect its adviser’s ability to make investment decisions that are suited to achieving the ETF’s investment objectives.

■	Government Money Market Funds. Investments in government money market funds are subject to interest rate risk, credit risk, and market risk.

Recently-Organized/Smaller Fund Risk
The current performance and expenses of a recently-organized and/or smaller fund, such as the Fund, may not represent how such fund is expected to, or may, perform in the long term if and when it becomes larger and has fully implemented its investment strategies. Investment positions may have a disproportionate impact (negative or positive) on performance in a recently-organized and/or smaller fund. The shareholder fees and annual fund operating expenses of a recently-organized and/or smaller fund may also be higher than those of a fund that has fully implemented its investment strategies and attracted sufficient assets to achieve investment and trading efficiencies. Recently-organized and/or smaller funds may also require a period of time before they are invested in securities that meet their investment objectives and policies and they achieve a representative portfolio composition. Fund performance may be lower or higher during this “ramp-up” period, and may also be more volatile, than would be the case after the fund is fully invested. Similarly, a recently-organized and/or smaller fund’s investment strategies may require a longer period of time to show returns that are representative of the strategies.

Sector Risk
When the Fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the Fund were invested more evenly across sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. As the Fund’s portfolio changes over time, the Fund’s exposure to a particular sector may become higher or lower.

Securities Lending Risk
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
Securities selected by the sub-advisor for the Fund may not perform to expectations. This could result in the Fund’s underperformance compared to its benchmark index(es), or other funds with similar investment objectives or strategies.

Small-Capitalization Companies Risk
Investing in the securities of small-capitalization companies involves greater risk and the possibility of greater price volatility 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 interest rates, borrowing costs and earnings.

Valuation Risk
The Fund may value certain assets 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 Fund’s ability to value its 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
Value stocks are subject to the risk that their intrinsic value may never be realized by the market or that their prices may decline. 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, which is the Fund’s benchmark index, for the periods indicated.

In the table below, the performance of the A Class and C Class shares for periods prior to February 1, 2021, represents the performance of the Investor Class shares of the Fund. The A Class and C Class shares would have had similar annual returns to the Investor Class shares of the Fund because the shares of each class represent investments in the same portfolio securities. However, the Investor Class shares of the Fund had different expenses than the A Class and C Class shares, which would affect performance. As the expenses of the C Class shares are higher than the expenses of the Investor Class shares, the returns of the C Class shares for periods prior to February 1, 2021 would be less than those shown below. The A Class and C Class performance shown in the table has not been adjusted for differences in operating expenses between the A Class and C Class shares and the Investor Class shares, but the A Class and C Class shares performance has been adjusted for the impact of the maximum applicable sales charge.

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.
