INVESTMENT OBJECTIVE

The FPA Global Allocation ETF (the "Fund") seeks long-term, risk-adjusted growth of capital.

FEES AND EXPENSES OF THE FUND

This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund ("Shares"). Investors may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example set forth below.

¹​ "Other Expenses" and "Acquired Fund Fees and Expenses" have been estimated for the current fiscal year. Actual expenses may differ from estimates.

²​ The Fund's investment adviser has contractually agreed to limit Total Annual Fund Operating Expenses (excluding any leverage interest, brokerage fees and commissions, acquired fund fees and expenses ("AFFE") (except as noted below), borrowing costs (such as interest and dividend expense on securities sold short), taxes, expenses incurred in connection with any merger or reorganization, and extraordinary expenses, such as litigation expenses), to 0.49% of the Fund's average daily net assets through May 31, 2028. The Fund's investment adviser may recoup any operating expenses in excess of these limits from the Fund within three years after the date of such payment if such recoupment can be achieved within the lesser of the foregoing expense limits and the expense limits in place at the time of recoupment. This agreement may only be terminated before its expiration date by the Board of Trustees of Investment Managers Series Trust III. In addition, the Fund's investment adviser has contractually agreed to waive all AFFE related to investments in affiliated Underlying Funds (defined below) and to waive up to 0.25% of AFFE related to investments in unaffiliated Underlying Funds, through at least May 31, 2028, to the extent necessary to offset the management fees that are borne by the Fund as a result of the Fund's investment in Underlying Funds.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. This example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell 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 at current levels. The example reflects the Fund's contractual fee

waiver only for the term of the contractual fee waiver. This example does not include the brokerage commissions that investors may pay to buy and sell Shares.

Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

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 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. The Fund's portfolio turnover rate may vary from year to year as well as within a year. The Fund is newly-created and, as a result, does not yet have a portfolio turnover rate.

PRINCIPAL INVESTMENT STRATEGIES

The Fund is an actively managed exchange-traded fund ("ETF") that seeks to achieve its investment objective by owning a balanced portfolio of global equity investments and fixed income investments. The Fund expects to operate as a "fund of funds" investing primarily in shares of other registered investment companies managed by First Pacific Advisors, LP (the "Adviser") (including other series of the Trust) and unaffiliated registered investment companies (collectively, "Underlying Funds") but is also permitted to invest directly in securities and other investments in lieu of, or in addition to, investing in Underlying Funds.

Under normal circumstances, the Adviser intends to invest at least approximately 50% of the Fund's net assets in global equity investments, including Underlying Funds that invest primarily in equities. The Adviser may engage in frequent and active trading to achieve the Fund's investment objective, especially when there is pronounced volatility in equities and fixed income markets. The Fund may invest in publicly traded common stocks of U.S. and non-U.S. issuers (i.e., if the issuer is headquartered outside the United States, if at least 50% of its assets are outside the United States, or if at least 50% of its gross income is from non-U.S. sources), including issuers in emerging market countries. The equity securities held directly by the Fund or indirectly (through an Underlying Fund) may include common stocks, real estate investment trusts ("REITs"), and depositary receipts. With respect to its direct or indirect (through an Underlying Fund) investments in equity securities, the Fund may invest in securities of any market capitalization. Under normal circumstances, the Fund expects to invest at least 40% of its equity assets in non-U.S. issuers.

The Fund's fixed income securities include securities that pay a fixed or fluctuating rate of interest, securities convertible into equity securities, securities issued or guaranteed by the U.S. federal government, state governments or by their agencies and instrumentalities, securities issued or guaranteed by foreign governments, international agencies or supranational entities, securities issued or guaranteed by domestic or foreign private issuers, mortgage-backed securities, asset-backed securities, inflation-indexed bonds, structured notes, loan assignments and loan participations. The Fund may also invest directly or indirectly (through an Underlying Fund) in below investment-grade debt securities (commonly referred to as "junk bonds"). Investment-grade debt securities are those rated in BBB- or higher categories by S&P Global Ratings, a division of S&P Global Inc. ("S&P") or the equivalent rating by any other nationally recognized statistical rating organization ("NRSRO") such as Moody's Investors Service, Inc. ("Moody's"), Fitch Ratings Ltd. ("Fitch") and others, or, if unrated, determined by the Adviser to be of comparable credit quality. The Fund may invest directly or indirectly (through an Underlying Fund) in fixed income securities of varying duration and maturities.

The Adviser uses its proprietary qualitative and quantitative research to assess the relative risk/reward of each asset class and other factors, which include but are not limited to absolute and relative equity valuations and high yield spreads, to determine the asset classes in which the Fund invests and how much the Fund invests in each asset class.

The Adviser then evaluates various combinations of affiliated or unaffiliated funds, securities and other investments to obtain the desired exposures and invests accordingly. The Adviser changes the Fund's asset class exposures in response to changes in the Adviser's assessment of individual securities and market risk/reward. The factors the Adviser considers and investment methods the Adviser uses can change over time. The Adviser may engage in frequent and active trading to achieve the Fund's investment objective, especially when there is pronounced volatility in equities and fixed income markets.

The Fund is classified as "non-diversified," meaning that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund.

The Adviser may sell all or a portion of a position held in the Fund when, in its opinion, one or more of the following occurs, among other reasons: (1) the portfolio managers determine that a security or asset class has a less favorable relative and/or absolute risk adjusted return profile than that of other securities or asset classes identified by the Adviser; or (2) the portfolio managers identify a more attractive opportunity.

PRINCIPAL RISKS

Risk is inherent in all investing and you could lose money by investing in the Fund. Before you decide whether to invest in the Fund, carefully consider these risk factors associated with investing in the Fund, which may cause investors to lose money. There can be no assurance that the Fund will achieve its investment objective.

Market Risk. The market price of a security or instrument may decline, sometimes rapidly or unpredictably, due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic, political, or geo-political conditions throughout the world, changes in the general outlook for corporate earnings, changes in interest or currency rates, or adverse investor sentiment generally. The market value of a security or instrument also may decline because of factors that affect a particular industry or industries, such as tariffs, labor shortages or increased production costs and competitive conditions within an industry. In addition, local, regional or global events such as war, acts of terrorism, international conflicts, trade disputes, supply chain disruptions, cybersecurity events, technological advances (such as artificial intelligence and machine learning), the spread of infectious illness or other public health issues, natural disasters or climate events, or other events could have a significant impact on a security or instrument. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market.

Underlying Fund Risk. Investing in Underlying Funds will provide the Fund with exposure to the risks of owning the underlying securities the ETFs or mutual funds hold. Shares of ETFs typically trade on securities exchanges and may at times trade at a premium or discount to their net asset values. In addition, an ETF or a mutual fund, if the mutual fund is an index fund, may not replicate exactly the performance of the benchmark index it seeks to track for a number of reasons, including transaction costs incurred by the ETF or mutual fund, the temporary unavailability of certain index securities in the secondary market, or discrepancies between the ETF or mutual fund and the index with respect to the weighting of securities or the number of securities held. It may be more expensive for the Fund to invest in an ETF or mutual fund than to own the portfolio securities of these investment vehicles directly. Investing in ETFs and mutual funds, which are investment companies, involves duplication of advisory fees and certain other expenses. The Fund will pay brokerage commissions in connection with the purchase and sale of shares of ETFs. In addition, the Fund may invest in Underlying Funds which invest a larger portion of their assets in one or more sectors than many other mutual funds, and thus will be more susceptible to negative events affecting those sectors.

The Fund may invest in affiliated Underlying Funds managed by the Adviser. The Adviser may be subject to potential conflicts of interest in selecting Underlying Funds because the management fees paid to it by certain affiliated Underlying Funds are higher than the fees paid by other affiliated and unaffiliated Underlying Funds. To the extent the Fund invests a significant percentage of its assets in any one affiliated Underlying Fund or across multiple affiliated Underlying Funds, the Fund will be subject to a greater degree to the risks particular to the investment strategies employed by the Adviser.

Asset Allocation Risk. The Fund, either directly or indirectly through its investments in Underlying Funds, may allocate its investments among various asset classes. The Fund's performance will be affected by the Adviser's selection of the Underlying Funds and the allocation of the Fund's assets among the various asset classes and market segments and may cause the Fund to underperform other funds with a similar investment objective. In addition, the Fund's performance will be affected by the Underlying Funds' performance and ability to meet their investment objectives.

Equity Risk. Equity securities, generally common stocks, held by the Fund or certain Underlying Funds may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect the securities markets generally, such as adverse changes in economic or political conditions, the general outlook for corporate earnings, interest rates or investor sentiment. Sustained periods of market volatility, either globally or in any jurisdiction in which the Fund or an Underlying Fund invests, may increase the risks associated with an investment in an Underlying Fund or the Fund. Equity securities may also lose value because of factors affecting an entire industry or sector, such as increases in production costs, or factors directly related to a specific company, such as decisions made by its management. Equity securities generally have greater price volatility than debt securities.

Foreign Investment Risk. The prices of foreign securities may be more volatile than the prices of securities of U.S. issuers because of economic and social conditions abroad, political developments, and changes in the regulatory environments of foreign countries. Changes in exchange rates and interest rates, and the imposition of sanctions, confiscations, trade restrictions (including tariffs) and other government restrictions by the United States and/or other governments may adversely affect the values of the Fund's or an Underlying Fund's foreign investments. Foreign companies are generally subject to different legal and accounting standards than U.S. companies, and foreign financial intermediaries may be subject to less supervision and regulation than U.S. financial firms. Foreign securities include American Depositary Receipts ("ADRs"), European Depository Receipts ("EDRs") and Global Depositary Receipts ("GDRs"). Unsponsored ADRs, EDRs and GDRs are organized independently and without the cooperation of the foreign issuer of the underlying securities, and involve additional risks because U.S. reporting requirements do not apply. In addition, the issuing bank may deduct shareholder distribution, custody, foreign currency exchange, and other fees from the payment of dividends.

Emerging Markets Securities Risk. Many of the risks with respect to foreign investments are more pronounced for investments in issuers in developing or emerging market countries. Emerging market countries tend to have more government exchange controls, more volatile interest and currency exchange rates, less market regulation, and less developed and less stable economic, political and legal systems than those of more developed countries. There may be less publicly available and reliable information about issuers in emerging markets than is available about issuers in more developed markets. In addition, emerging market countries may experience high levels of inflation and may have less liquid securities markets and less efficient trading and settlement systems.

Fixed Income Securities Risk. The prices of fixed income securities respond to economic developments, particularly interest rate changes, as well as to changes in an issuer's credit rating or market perceptions about the creditworthiness of an issuer. Generally, fixed income securities decrease in value if interest rates rise and increase in value if interest rates fall, and longer-term and lower rated securities are more volatile than shorter-term and higher rated securities.

Interest Rate Risk. Generally fixed income securities decrease in value if interest rates rise and increase in value if interest rates fall, with longer-term securities being more sensitive than shorter-term securities. For example, the price of a security with a three-year duration would be expected to drop by approximately 3% in response to a one percentage point increase in interest rates, all things being equal. Falling interest rates also create the potential for a decline in the Fund's or an Underlying Fund's income. Changes in governmental policy, rising inflation rates, and general economic developments, among other factors, could cause interest rates to increase and could have a substantial and immediate effect on the values of the Fund's or an Underlying Fund's investments. In addition, a potential rise in interest rates may result in periods of volatility and increased redemptions that might require the Fund to liquidate portfolio securities at disadvantageous prices and times.

Credit Risk. If an issuer or guarantor of a debt security held by the Fund or an Underlying Fund, or a counterparty to a financial contract with the Fund or an Underlying Fund, defaults or is downgraded or is perceived to be less creditworthy, or if the value of the assets underlying a security declines, the value of that security may also decline.

Risks Associated with Investing in High Yield Securities. High yield bonds, which are sometimes called "junk" bonds, are highly speculative securities that are usually issued by smaller, less credit- worthy and/or highly leveraged (indebted) companies. High yield securities are generally subject to greater levels of credit, call and liquidity risks than higher-rated securities of similar maturity. In addition, such securities may, under certain circumstances, be less liquid than higher rated securities. These securities pay investors a premium (a high interest rate or yield) because of the potential illiquidity and increased risk of loss. These securities can also be subject to greater price volatility. In times of unusual or adverse market, economic or political conditions, these securities may experience higher than normal default rates.

Risks Associated with Investing in Sovereign and Government-Related Debt. Sovereign debt includes securities issued or guaranteed by a non-U.S. sovereign government or its agencies, authorities, or political subdivisions. Government-related debt includes securities issued by non-U.S. regional or local governmental entities or government-controlled entities. In the event an issuer of sovereign debt or government-related debt is unable or unwilling to make scheduled payments of interest or principal, holders may be asked to participate in a restructuring of the debt and to extend further credit to the issuer. In the event of a default by such an issuer, there may be few or no effective legal remedies for collecting on such debt.

REIT Risk. The Fund's or an Underlying Fund's investment in REITs will subject the Fund or such Underlying Fund to risks similar to those associated with direct ownership of real estate, including losses from casualty or condemnation, and changes in local and general economic conditions, supply and demand, interest rates, zoning laws, regulatory limitations on rents, property taxes and operating expenses.

Mortgage-Related and Asset-Backed Securities Risk. Mortgage-related and other asset-backed securities represent interests in "pools" of mortgages or other assets such as consumer loans or receivables held in trust and often involve risks that are different from or possibly more acute than risks associated with other types of debt instruments. Mortgage-related securities, including commercial mortgage-backed securities ("CMBS") and residential mortgage-backed securities ("RMBS") are subject to prepayment risk (the risk that borrowers will repay a loan more quickly in periods of falling interest rates) and "extension risk" (the risk that borrowers will repay a loan more slowly in periods of rising interest rates) and can be highly sensitive to changes in interest rates. Mortgage-backed securities, and in particular those not backed by a government guarantee, are subject to credit risk. The Fund's or an Underlying Fund's investments in other asset-backed securities are subject to risks similar to those associated with mortgage-related securities, as well as additional risks associated with the nature of the assets and the servicing of those assets.

Market Capitalization Risk. Larger, more established companies may be unable to attain the high growth rates of successful, smaller companies during periods of economic expansion. The securities of small-capitalization or mid-capitalization companies may be subject to more abrupt or erratic market movements and may have lower trading volumes or more erratic trading than securities of larger, more established companies or market averages in general. In addition, such companies typically are more likely to be adversely affected than large capitalization companies by changes in earning results, business prospects, investor expectations or poor economic or market conditions.

Issuer Risk. Issuer-specific attributes may cause a security held by the Fund or an Underlying Fund to be more volatile than the market generally. The prices of, and income generated by, securities held by the Fund or an Underlying Funds may decline in response to various factors directly related to the issuers of such securities, including reduced demand for an issuer's goods or services, poor management performance, major litigation, investigations or other controversies related to the issuer, changes in the issuer's financial condition or credit rating, changes in government regulation affecting the issuer or its competitive environment, and strategic initiatives such as mergers, acquisitions or dispositions and the market response to any such initiatives. An individual security may also be affected by factors related to the industry or sector of the issuer or the securities markets as a whole, and conversely an industry or sector or the securities markets may be affected by a change in financial condition or

another event affecting a single issuer. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. At times, the Fund or any Underlying Fund may invest more significantly in a single issuer, which could increase the Fund's or such Underlying Fund's volatility and the risk of loss arising from the factors described above.

Active Management Risk. The Fund is actively managed by its portfolio managers. There is a risk that an investment technique used by the Fund's portfolio managers may fail to produce the intended result. The Adviser's judgments about the growth, value or potential appreciation of an investment may prove to be incorrect or fail to have the intended results, which could adversely impact the Fund's performance and cause it to underperform relative to other funds with similar investment goals or not to achieve its investment goal.

Portfolio Turnover Risk. Active and frequent trading of the Fund's portfolio securities may lead to higher transaction costs and may result in a greater number of taxable transactions than would otherwise be the case, which could negatively affect the Fund's performance. A high rate of portfolio turnover is 100% or more.

Volatility Risk. The Fund or an Underlying Fund may have investments that appreciate or decrease significantly in value over short periods of time. This may cause the Fund's or such Underlying Fund's net asset value per share ("NAV") to experience significant increases or declines in value over short periods of time.

ETF Structure Risks. The Fund is an ETF, and, as a result of an ETF's structure, it is exposed to the following risks:

• Authorized Participant Concentration Risk. Only an authorized participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that act as authorized participants on an agency basis (i.e., on behalf of other market participants). To the extent that these institutions exit the business or are unable to proceed with creation and/or redemption orders with respect to the Fund and no other authorized participant is able to step forward to process creation or redemption orders, Shares may trade at a discount to the Fund's NAV and possibly face delisting.

• Cash Transaction Risk. To the extent the Fund sells portfolio securities to meet some or all of a redemption request with cash, the Fund may incur taxable gains or losses that it might not have incurred had it made redemptions entirely in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.

• Market Maker Risk. If the Fund has lower average daily trading volumes, it may rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares. Any trading halt or other problem relating to the trading activity of these market makers could result in a dramatic change in the spread between the Fund's NAV and the price at which the Fund Shares are trading on the Exchange, which could result in a decrease in value of the Fund Shares. In addition, decisions by market makers or authorized participants to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund's portfolio securities and the Fund's market price. This reduced effectiveness could result in Fund Shares trading at a discount to NAV and also in greater than normal intra-day bid-ask spreads for Fund Shares.

• Fluctuation of NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund's NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). Differences in market price and NAV may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for Shares will be closely related to, but not identical to, the same forces influencing the prices of the holdings of the Fund trading individually or in the aggregate at any point in time. These differences can be especially pronounced during times of market volatility or stress. During these periods, the demand for Fund Shares may decrease considerably and cause the market price of Fund Shares to deviate significantly from the Fund's NAV.

• Market Price Could Vary From NAV Due to Foreign Holdings. The Fund may hold shares of non-U.S. securities traded in local markets that close at a different time than the Exchange. To the extent underlying securities held by the Fund trade on foreign exchanges that are closed when the Exchange is open, there may be deviations between the current price of an underlying security and the last quoted price for the underlying security on the closed foreign market. This could lead to differences between the market price of the Fund's Shares and the underlying value of the Fund Shares. These differences can be magnified during times of significant market activity.

• Trading Issues Risk. Although the Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for such Fund Shares will develop or be maintained. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange "circuit breaker" rules. Market makers are under no obligation to make a market in the Fund Shares, and authorized participants are not obligated to submit purchase or redemption orders for Creation Units. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. Initially, due to the small asset size of the Fund, it may have difficulty maintaining its listings on the Exchange.

• Costs of Buying or Selling Shares. Investors buying or selling Shares in the secondary market will pay brokerage commissions or other charges imposed by brokers, as determined by that broker. Brokerage commissions are often a fixed amount and may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Shares. In addition, secondary market investors will also incur the cost of the difference between the price at which an investor is willing to buy Shares (the "bid" price) and the price at which an investor is willing to sell Shares (the "ask" price). This difference in bid and ask prices is often referred to as the "spread" or "bid-ask spread." The bid-ask spread varies over time for Shares based on trading volume and market liquidity, and the spread is generally lower if Shares have more trading volume and market liquidity and higher if Shares have little trading volume and market liquidity. Further, a relatively small investor base in the Fund, asset swings in the Fund, and/or increased market volatility may cause increased bid-ask spreads. Due to the costs of buying or selling Shares, including bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.

• Shares are Not Individually Redeemable. Shares are only redeemable by the Fund at NAV if they are tendered in Creation Units. Only APs may engage in such creation and redemption transactions directly with the Fund. Individual Shares may be sold on a stock exchange at their current market prices, which may be less, more, or equal to their NAV.

U.S. Government Securities Risk. Certain U.S. government securities are supported by the full faith and credit of the United States; others are supported by the right of the issuer to borrow from the U.S. Treasury; others are supported by the discretionary authority of the U.S. government to purchase the agency's obligations; and still others are supported only by the credit of the issuing agency, instrumentality, or enterprise. Although U.S. government-sponsored enterprises such as the Federal Home Loan Mortgage Corporation (Freddie Mac) and the Federal National Mortgage Association (Fannie Mae) may be chartered or sponsored by Congress, they are not funded by Congressional appropriations, and their securities are not issued by the U.S. Treasury, are not supported by the full faith and credit of the U.S. government, and involve increased credit risks in comparison to U.S. Treasury securities or other securities supported by the full faith and credit of the U.S. government.

Non-Diversified Risk. The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund's volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund's performance.

No Operating History. The Fund is newly organized and has no operating history. As a result, prospective investors have no track record or history on which to base their investment decisions.

Recent Market Events. Periods of market volatility may occur in response to market events, public health emergencies, natural disasters or climate events, and other economic, political, and global macro factors. U.S. and international markets have recently experienced, and may continue to experience, periods of significant volatility due to various factors, including uncertainty regarding inflation and central banks' interest rate changes, the possibility of a national or global recession, trade tensions and tariffs, and political and geopolitical events. In addition, wars or threats of war and aggression, such as Russia's invasion of Ukraine and the conflicts among nations and militant groups in the Middle East, have led, and in the future may lead, to increased short-term market volatility and may have adverse long-term effects on the U.S. and world economies and markets generally, each of which may negatively impact the Fund's investments. Additionally, since the change in the U.S. presidential administration in 2025, the administration has pursued an aggressive foreign policy agenda, including through suggestions that the United States should control certain sovereign foreign territories, attempts to restructure federal government agencies with international influence, and the imposition of tariffs, and trade barriers on certain foreign countries, including China and long-time U.S. allies. These and other similar events could be prolonged and could adversely affect the value and liquidity of the Fund's investments, impair the Fund's ability to satisfy redemption requests, and negatively impact the Fund's performance.

Cybersecurity Risk. Cybersecurity incidents may allow an unauthorized party to gain access to Fund assets, customer data (including private shareholder information), or proprietary information, or cause the Fund, the Adviser and/or other service providers (including custodians, sub-custodians, transfer agents and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality. In an extreme case, a shareholder's ability to exchange or redeem Fund shares may be affected. The use of artificial intelligence and machine learning could exacerbate these risks. Issuers of securities in which the Fund or an Underlying Fund invests are also subject to cybersecurity risks, and the value of those securities could decline if the issuers experience cybersecurity incidents.

PERFORMANCE

The Fund is new and does not have a full calendar year performance record to compare against other mutual funds or broad measures of securities market performance such as indices. Updated performance information will be available on the Fund's website at https://fpaa.fpa.com.

MANAGEMENT

Investment Adviser

First Pacific Advisors, LP serves as the Fund's investment adviser.

PORTFOLIO MANAGERS

Steven Romick, CFA, a Managing Partner of the Adviser, Mark Landecker, CFA, Partner of the Adviser, and Brian A. Selmo, CFA, Partner of the Adviser, serve as portfolio managers of the Fund. Messrs. Romick, Landecker and Selmo are jointly and primarily responsible for the day-to-day management of the Fund and each has served as portfolio manager of the Fund since its inception in June 2026.

PURCHASE AND SALE OF SHARES

The Fund issues and redeems Shares on a continuous basis, at NAV, only in large blocks of shares called "Creation Units." Except when aggregated in Creation Units, the Shares are not redeemable securities of the Fund.

Individual Shares of the Fund may only be purchased and sold on the secondary market through a broker-dealer. Since Shares of the Fund trade on securities exchanges in the secondary market at their market price rather than

their NAV, the Fund's Shares may trade at a price greater than (premium) or less than (discount) the Fund's NAV. An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase Shares of the Fund (bid) and the lowest price a seller is willing to accept for Shares of the Fund (ask) when buying or selling Shares in the secondary market (the "bid-ask spread"). Recent information, including the Fund's NAV, market price, premiums and discounts, and bid-ask spreads, is available online at https://fpaa.fpa.com.

TAX INFORMATION

The Fund's distributions will generally be taxable as ordinary income, returns of capital or capital gains. A sale of Shares may result in capital gain or loss.

PAYMENTS TO BROKER-DEALERS AND OTHER FINANCIAL INTERMEDIARIES

If you purchase Shares through a broker-dealer or other financial intermediary (such as a bank), the Adviser and Distribution Services, LLC, the Fund's distributor, may pay the intermediary for the sale of Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.
