FPA Short Duration Government ETF

Item 7. Financial Statements and Financial Highlights for Open-End Management Investment Companies.

This report and the financial statements contained herein are provided for the general information of the shareholders of the FPA Global Equity ETF (the “ETF”). This report is not authorized for distribution to prospective investors in the ETF unless preceded or accompanied by an effective shareholder report and prospectus.

FPA Global Equity ETF (the “Fund”) is a non-diversified series of Investment Managers Series Trust III (the “Trust”), which is registered as an open-end management company under the Investment Company Act of 1940, as amended (the “1940 Act”). The Fund’s investment objective is long-term growth of principal and income. First Pacific Advisers, LP (the “Adviser”) has served as the Fund’s investment Adviser since December 16, 2021.

On April 26, 2024, the Fund acquired the assets and assumed the liabilities of FPA Global Equity ETF, a series of Northern Lights Fund Trust III, (the “Predecessor Fund”) in a tax-free reorganization pursuant to the Agreement and Plan of Reorganization (the “Plan of Reorganization”). The Plan of Reorganization was approved by the Trust’s Board on October 24, 2023. The Predecessor Board approved the Plan of Reorganization on November 21, 2023. The tax-free reorganization was accomplished on April 27, 2024. As a result of the reorganization, the Fund assumed the performance and accounting history of the Predecessor Fund. Financial information included for the dates prior to the reorganization is that of the Predecessor Fund.

The reorganization was accomplished by the following tax-free exchange in which each shareholder of the Fund received the same aggregate share net asset value as noted below:

The net unrealized appreciation of investments transferred was $10,296,832 as of the date of the acquisition.

The Fund is an investment company and accordingly follows the investment company accounting and reporting guidance of the Financial Accounting Standards Board (FASB) Accounting Standard Codification Topic 946 “Financial Services — Investment Companies”.

The Fund is deemed to be an individual reporting segment and is not part of a consolidated reporting entity. The objective and strategy of the Fund is used by the Adviser to make investment decisions, and the results of the operations, as shown on the Statements of Operations and the financial highlights for the Fund is the information utilized for the day-to-day management of the Fund. The Fund is party to the expense agreements as disclosed in the Notes to the Financial Statements and there are no resources allocated to a Fund based on performance measurements. The management of the Fund’s Adviser is deemed to be the Chief Operating Decision Maker with respect to the Fund's investment decisions.

The following is a summary of the significant accounting policies consistently followed by the Fund in the preparation of their financial statements. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from these estimates.

Investment transactions are accounted for on the trade date. Realized gains and losses on investments are determined on the identified cost basis. Dividend income is recorded net of applicable withholding taxes on the ex-dividend date and interest income is recorded on an accrual basis. Withholding taxes on foreign dividends, if applicable, are paid (a portion of which may be reclaimable) or provided for in accordance with the applicable country’s tax rules and rates and are disclosed in the Statement of Operations. Withholding tax reclaims are filed in certain countries to recover a portion of the amounts previously withheld. The Fund records a reclaim receivable based on a number of factors, including a jurisdiction’s legal obligation to pay reclaims as well as payment history and market convention. Expenses incurred by the Trust with respect to more than one fund are allocated in proportion to the net assets of each fund except where allocation of direct expenses to each fund or an alternative allocation method can be more appropriately made.

Fund Shares are listed and traded on the Exchange on each day that the Exchange is open for business (“Business Day”). Individual Fund Shares may only be purchased and sold on the Exchange through a broker-dealer. Because the Fund’s Shares trade at market prices rather than at their Net Asset Value (NAV), Shares may trade at a price equal to the NAV, greater than NAV (premium) or less than NAV (discount).

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, Shares are not redeemable securities of the Fund. Fund Shares may only be purchased from or redeemed to the Fund by certain financial institutions (“Authorized Participants”). An Authorized Participant is either (i) a broker-dealer or other participant in the clearing process through the Continuous Net Settlement System of the National Securities Clearing Corporation or (ii) a Depository Trust Company (“DTC”) participant and, in each case, must have executed a Participant Agreement with the Distributor. Creation Units are available for purchase and redemption on each Business Day and are offered and redeemed on an in-kind basis, together with the specified cash amount, or for an all cash amount.

To the extent contemplated by a participant agreement, in the event an Authorized Participant has submitted a redemption request in proper form but is unable to transfer all or part of the shares comprising a Creation Unit to be redeemed by the Distributor, on behalf of the Fund, by the time as set forth in a participant agreement, the Distributor may nonetheless accept the redemption request in reliance on the undertaking by the Authorized Participant to deliver the missing shares as soon as possible, which undertaking shall be secured by the Authorized Participant’s delivery and maintenance of collateral equal to a percentage of the market value as set forth in the Participant Agreement. A participant agreement may permit the Fund to use such collateral to purchase the missing shares, and could subject an Authorized Participant to liability for any shortfall between the cost of the Fund acquiring such shares and the value of the collateral.

Most retail investors will not qualify as Authorized Participants or have the resources to buy and sell whole Creation Units. Therefore, they will be unable to purchase or redeem the Shares directly from the Fund. Rather, most retail investors will purchase Shares in the secondary market with the assistance of a broker, which will be subject to customary brokerage commissions or fees.

A fixed purchase (i.e., creation) transaction fee is imposed for the transfer and other transaction costs associated with the purchase of Creation Units, and investors will be required to pay a creation transaction fee regardless of the number of Creation Units created in the transaction. The Fund may adjust the creation transaction fee from time to time based upon actual experience. In addition, a variable fee may be imposed for cash purchases, non-standard orders, or partial cash purchases of Creation Units. The variable fee is primarily designed to cover non-standard charges, e.g., brokerage, taxes, foreign exchange, execution, market impact, and other costs and expenses, related to the execution of trades resulting from such transaction. The Fund may adjust the non-standard charge from time to time based upon actual experience. Investors who use the services of an Authorized Participant, broker or other such intermediary may be charged a fee for such services which may include an amount for the creation transaction fee and non-standard charges. Investors are responsible for the costs of transferring the securities constituting the deposit securities to the account of the Trust. The Adviser may retain all or a portion of the transaction fee to the extent the Adviser bears the expenses that otherwise would be borne by the Trust in connection with the issuance of a Creation Unit, which the transaction fee is designed to cover. The standard fixed purchase transaction fee of a Creation Unit of the Fund is $400 for in-kind purchases and $100 for cash purchases, regardless of the number of Creation Units created in the transaction.

A fixed redemption transaction fee may be imposed for the transfer and other transaction costs associated with the redemption of Creation Units, and Authorized Participants will be required to pay a redemption transaction fee regardless of the number of Creation Units created in the transaction. The redemption transaction fee is the same no matter how many Creation Units are being redeemed pursuant to any one redemption request. The Fund may adjust the redemption transaction fee from time to time based upon actual experience. In addition, a variable fee, payable to the Fund, may be imposed for cash redemptions, non-standard orders, or partial cash redemptions for the Fund. The variable fee is primarily designed to cover non-standard charges, e.g., brokerage, taxes, foreign exchange, execution, market impact, and other costs and expenses, related to the execution of trades resulting from such transaction. Investors who use the services of an Authorized Participant, broker or other such intermediary may be charged a fee for such services which may include an amount for the redemption transaction fees and non-standard charges. Investors are responsible for the costs of transferring the securities constituting the Fund securities to the account of the Trust. The non-standard charges are payable to the Fund as it incurs costs in connection with the redemption of Creation Units, the receipt of Fund securities and the cash redemption amount and other transactions costs. The standard fixed redemption transaction fee of a Creation Unit of the Fund is $400 for in-kind redemptions and $100 for cash redemptions.

The Fund’s records are maintained in U.S. dollars. The value of securities, currencies and other assets and liabilities denominated in currencies other than U.S. dollars are translated into U.S. dollars based upon foreign exchange rates prevailing at the end of the reporting period. The currencies are translated into U.S. dollars by using the exchange rates quoted as of 4:00 PM Eastern Standard Time. Purchases and sales of investment securities, income and expenses are translated on the respective dates of such transactions.

The Fund does not isolate that portion of its net realized and unrealized gains and losses on investments resulting from changes in foreign exchange rates from the impact arising from changes in market prices. Such fluctuations are included with net realized and unrealized gain or loss from investments and foreign currency.

Net realized foreign currency transaction gains and losses arise from sales of foreign currencies, currency gains or losses realized between the trade and settlement dates on securities transactions, and the differences between the amounts of dividends, interest, and foreign withholding taxes recorded on the Fund’s books and the U.S. dollar equivalent of the amounts actually received or paid. Net unrealized foreign currency translation gains and losses arise from changes in the value of assets and liabilities, other than investments in securities, resulting from changes in the exchange rates.

The Fund intends to comply with the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its net investment income and any net realized gains to its shareholders. Therefore, no provision is made for federal income or excise taxes. Due to the timing of dividend distributions and the differences in accounting for income and realized gains and losses for financial statement and federal income tax purposes, the fiscal year in which amounts are distributed may differ from the year in which the income and realized gains and losses are recorded by the Fund.

Accounting for Uncertainty in Income Taxes (the “Income Tax Statement”) requires an evaluation of tax positions taken (or expected to be taken) in the course of preparing a Fund’s tax returns to determine whether these positions meet a “more-likely-than-not” standard that, based on the technical merits, have a more than fifty percent likelihood of being sustained by a taxing authority upon examination. A tax position that meets the “more-likely-than-not” recognition threshold is measured to determine the amount of benefit to recognize in the financial statements. The Fund recognizes interest and penalties, if any, related to unrecognized tax benefits as income tax expense in the Statement of Operations.

The Income Tax Statement requires management of the Fund to analyze tax positions taken in the prior three open tax years, if any, and tax positions expected to be taken in the Fund’s current tax year, as defined by the IRS statute of limitations for all major jurisdictions, including federal tax authorities and certain state tax authorities. As of March 31, 2026, and during the prior open tax years, the Fund did not have a liability for any unrecognized tax benefits. The Fund has no examination in progress and is not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months.

The Fund will make distributions of net investment income quarterly and net capital gains, if any, at least annually. Distributions to shareholders are recorded on the ex-dividend date. The amount and timing of distributions are determined in accordance with federal income tax regulations, which may differ from GAAP.

The character of distributions made during the year from net investment income or net realized gains may differ from the characterization for federal income tax purposes due to differences in the recognition of income, expense and gain (loss) items for financial statement and tax purposes.

Pursuant to Rule 22e-4 under the 1940 Act, the Fund has adopted a Liquidity Risk Management Program (“LRMP”) that requires, among other things, that the Fund limits its illiquid investments that are assets to no more than 15% of net assets. An illiquid investment is any security which may not reasonably be expected to be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment. If the Adviser, at any time, determines that the value of illiquid securities held by the Fund exceed 15% of its NAV, the Adviser will take such steps as it considers appropriate to reduce them as soon as reasonably practicable in accordance with the Fund’s written LRMP.

ETFs typically trade on securities exchanges and their shares may, at times, trade at a premium or discount to their net asset values. In addition, an ETF 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, the temporary unavailability of certain index securities in the secondary market or discrepancies between the ETF and the index with respect to the weighting of securities or the number of securities held. Investing in ETFs, which are investment companies, may involve duplication of Adviser fees and certain other expenses. As a result, Fund shareholders indirectly bear their proportionate share of these acquired expenses. Therefore, the cost of investing in the Fund will be higher than the cost of investing directly in ETFs and may be higher than other mutual funds that invest directly in securities.

Each ETF in which the Fund invests is subject to specific risks, depending on the nature of the ETF. Each ETF is subject to the risks associated with direct ownership of the securities comprising the index on which the ETF is based. These risks could include liquidity risk, sector risk as well as risks associated with fixed-income securities.

The Trust, on behalf of the Fund, entered into an Investment Adviser Agreement (the “Agreement”) with the Adviser. Under the terms of the Agreement, the Fund pays a monthly investment Adviser fee to the Adviser at the annual rate of 0.70% of the Fund’s average daily net assets.

The Adviser has contractually agreed to waive its fees and/or pay for operating expenses of the Fund to ensure that total annual fund operating expenses (excluding any front-end or contingent deferred loads, brokerage fees and commissions, acquired fund fees and expenses, borrowing costs (such as interest and dividend expense on securities sold short), taxes, and extraordinary expenses, such as litigation expenses (which may include indemnification of Fund officers and Trustees, contractual indemnification of Fund service providers (other than the Adviser))), do not exceed 0.49% of the Fund’s average daily net assets. This agreement is in effect until January 31, 2027. For the six months ended March 31, 2026, the Adviser waived a portion of its advisory fees totaling $462,268.

The adviser may recoup any operating expenses in excess of these limits from the Fund within three years 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 be terminated by the Board only on 60 days’ written notice to the Adviser. In addition, the adviser may seek reimbursement from the Fund of fees waived or payments made by the adviser to the Predecessor Fund prior to the Predecessor Fund’s reorganization for a period ending three years after the date of the waiver or payment if such recoupment can be achieved within the lesser of the foregoing expense limited and the expense limits in place at the time of the recoupment. The potential recoverable amount is noted as “Commitments and contingencies” as reported on the Statement of Assets and Liabilities. As of March 31, 2026, the Adviser may seek recoupment for previously waived or reimbursed expenses, subject to the limitations noted above, no later than the dates as outlined below:

Brown Brothers Harriman & Co. (“BBH”) serves as the Fund’s fund accountant, transfer agent, and custodian. UMB Fund Services, Inc. (“UMBFS”) serves as the Fund’s co-administrator; and Mutual Fund Administration, LLC (“MFAC”) serves as the Fund’s other co-administrator. The Fund’s allocated fees incurred for fund accounting, fund administration, transfer agency and custody services for the six months ended March 31, 2026, are reported as fund services fees on the Statement of Operations.

Distribution Services, LLC, serves as the Fund’s distributor (the “Distributor”). The Distributor does not receive compensation from the Fund for its distribution services. The Adviser pays the Distributor a fee for its distribution-related services.

Certain trustees and officers of the Trust are employees of UMBFS, MFAC or Adviser. The Fund does not compensate trustees and officers affiliated with the Fund’s Adviser or co-administrators. For the six months ended March 31, 2026, the Fund’s allocated fees incurred to Trustees of the Trust who are not “interested persons” of the Trust, as that term is defined in the 1940 Act (collectively, the “Independent Trustees”) are reported on the Statement of Operations.

The Fund's Board of Trustees has adopted a Deferred Compensation Plan (the “Plan”) for the Independent Trustees that enables Trustees to elect to receive payment in cash or the option to defer some or all of their fees. If a trustee elects to defer payment, the Plan provides for the creation of a deferred payment account. A Trustee’s deferred fees are deemed to be invested in designated mutual funds available under the Plan. The Fund's liability for these amounts is adjusted for market value changes in the invested fund and remains a liability to the Fund until distributed in accordance with the Plan. The Trustees Deferred compensation liability under the Plan constitutes a general unsecured obligation of the Fund and is disclosed in the Statement of Assets and Liabilities. Contributions made under the plan and the change in unrealized appreciation/depreciation and income are included in the Trustees' fees and expenses in the Statement of Operations.

Dziura Compliance Consulting, LLC provides Chief Compliance Officer (“CCO”) services to the Trust. The Fund’s allocated fees incurred for CCO services for the six months ended March 31, 2026, are reported on the Statement of Operations.

At March 31, 2026, gross unrealized appreciation and depreciation on investments owned by the Fund, based on cost for federal income tax purposes were as follows:

The difference between cost amounts for financial statement and federal income tax purposes is due primarily to timing differences in recognizing certain gains and losses in security transactions.

For the six months ended March 31, 2026, purchases and sales of investments, excluding in-kind transactions and short-term investments, were $109,426,624 and $56,046,243, respectively. Purchases, sales, and realized gain/(loss) of in-kind transactions for the six months ended March 31, 2026 were $145,364,173, $48,262,858, and $17,240,402, respectively.

In the normal course of business, the Fund enters into contracts that contain a variety of representations which provide general indemnifications. The Fund’s maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred. However, the Fund expects the risk of loss to be remote.

Fair Value Measurements and Disclosures defines fair value, establishes a framework for measuring fair value in accordance with GAAP, and expands disclosure about fair value measurements. It also provides guidance on determining when there has been a significant decrease in the volume and level of activity for an asset or a liability, when a transaction is not orderly, and how that information must be incorporated into a fair value measurement.

Under Fair Value Measurements and Disclosures, various inputs are used in determining the value of the Fund’s investments. These inputs are summarized into three broad Levels as described below:

The availability of observable inputs can vary from security to security and is affected by a wide variety of factors, including, for example, the type of security, whether the security is new and not yet established in the marketplace, the liquidity of markets, and other characteristics particular to the security. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised in determining fair value is greatest for instruments categorized in Level 3.

The inputs used to measure fair value may fall into different Levels of the fair value hierarchy. In such cases, for disclosure purposes, the Level in the fair value hierarchy within which the fair value measurement falls in its entirety, is determined based on the lowest Level input that is significant to the fair value measurement in its entirety.

The inputs or methodology used for valuing securities are not an indication of the risk associated with investing in those securities. The following is a summary of the inputs used, as of March 31, 2026, in valuing the Fund’s assets carried at fair value:

For purposes of the 1940 Act, the Fund is treated as a registered investment company. Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies, including shares of the Fund. Rule 12d1-4 of the 1940 Act permits other investment companies to invest in the Fund beyond the limits in Section 12(d)(1), subject to certain terms and conditions, including that such investment companies enter into an agreement with the Fund.

Certain local, regional, or global events such as war, acts of terrorism, the spread of infectious illness and/or other public health issues, financial institution instability or other events may have a significant impact on a security or instrument. These types of events and other like them are collectively referred to as “Market Disruptions and Geopolitical Risks” and they may have adverse impacts on the worldwide economy, as well as the economies of individual countries, the financial health of individual companies and the market in general in significant and unforeseen ways. Some of the impacts noted in recent times include but are not limited to embargos, political actions, supply chain disruptions, tariffs, bank failures, restrictions to investment and/or monetary movement including the forced selling of securities or the inability to participate impacted markets. The duration of these events could adversely affect the Fund’s performance, the performance of the securities in which the Fund invests and may lead to losses on your investment. The ultimate impact of “Market Disruptions and Geopolitical Risks” on the financial performance of the Fund’s investments is not reasonably estimable at this time. Management is actively monitoring these events.

In the reporting period, the Fund adopted FASB Accounting Standards Update 2023-09, Income Taxes (Topic 740) — Improvements to Income Tax Disclosures (ASU 2023-09), which enhances income tax disclosures, including disclosure of income taxes paid disaggregated by jurisdiction. The standard is an annual disclosure requirement and Fund Management is evaluating the impacts of these changes to the Fund’s financial statements.

The Fund has adopted financial reporting rules regarding subsequent events which require an entity to recognize in the financial statements the effects of all subsequent events that provide additional evidence about conditions that existed at the date of the balance sheet. Management has evaluated the Fund’s related events and transactions that occurred through the date of issuance of the Fund’s financial statements.

There were no events or transactions that occurred during this period that materially impacted the amounts or disclosures in the Fund’s financial statements.

This report and the financial statements contained herein are provided for the general information of the shareholders of the FPA Short Duration Government ETF (the “ETF”). This report is not authorized for distribution to prospective investors in the ETF unless preceded or accompanied by an effective shareholder report and prospectus.

FPA Short Duration Government ETF (the “Fund”) is a diversified series of Investment Managers Series Trust III (the “Trust”), which is registered as an open-end management company under the Investment Company Act of 1940, as amended (the “1940 Act”). The Fund’s primary investment objective is to provide long-term total return, which includes income and capital appreciation, while considering capital preservation. First Pacific Advisors, LP (the “Adviser”) has served as the Fund’s investment adviser since October 31, 2024.

The Fund values equity securities at the last reported sale price on the principal exchange or in the principal over the counter (“OTC”) market in which such securities are traded, as of the close of regular trading on the NYSE on the day the securities are being valued or, if the last-quoted sales price is not readily available, the securities will be valued at the last bid or the mean between the last available bid and ask price. Securities traded on the NASDAQ are valued at the NASDAQ Official Closing Price (“NOCP”). Investments in open-end investment companies are valued at the daily closing net asset value of the respective investment company. Debt securities are valued by utilizing a price supplied by independent pricing service providers. The independent pricing service providers may use various valuation methodologies including matrix pricing and other analytical pricing models as well as market transactions and dealer quotations. These models generally consider such factors as yields or prices of bonds of comparable quality, type of issue, coupon, maturity, ratings and general market conditions. If a price is not readily available for a portfolio security, the security will be valued at fair value (the amount which the Fund might reasonably expect to receive for the security upon its current sale). The Board of Trustees has designated the Adviser as the Fund’s valuation designee (the “Valuation Designee”) to make all fair value determinations with respect to the Fund’s portfolio investments, subject to the Board’s oversight. As the Valuation Designee, the Adviser has adopted and implemented policies and procedures to be followed when the Fund must utilize fair value pricing.

Investment transactions are accounted for on the trade date. Realized gains and losses on investments are determined on the identified cost basis. Dividend income is recorded net of applicable withholding taxes on the ex-dividend date and interest income is recorded on an accrual basis. Withholding taxes on foreign dividends, if applicable, are paid (a portion of which may be reclaimable) or provided for in accordance with the applicable country’s tax rules and rates and are disclosed in the Statement of Operations. Withholding tax reclaims are filed in certain countries to recover a portion of the amounts previously withheld. The Fund records a reclaim receivable based on a number of factors, including a jurisdiction’s legal obligation to pay reclaims as well as payment history and market convention. Discounts on debt securities are accreted or amortized to interest income over the lives of the respective securities using the effective interest method. Premiums for callable debt securities are amortized to the earliest call date if the call price was less than the purchase price. If the call price was not at par and the security was not called, the security is amortized to the next call price and date. Expenses incurred by the Trust with respect to more than one fund are allocated in proportion to the net assets of each fund except where allocation of direct expenses to each fund or an alternative allocation method can be more appropriately made.

Fund Shares are listed and traded on the Exchange on each day that the Exchange is open for business (“Business Day”). Individual Fund Shares may only be purchased and sold on the Exchange through a broker-dealer. Because the Fund’s Shares trade at market prices rather than at their Net Asset Value (“NAV”), Shares may trade at a price equal to the NAV, greater than NAV (premium) or less than NAV (discount).

The Income Tax Statement requires management of the Fund to analyze tax positions taken in the prior three open tax years, if any, and tax positions expected to be taken in the Fund’s current tax year, as defined by the IRS statute of limitations for all major jurisdictions, including federal tax authorities and certain state tax authorities. As of March 31, 2026, the Fund did not have a liability for any unrecognized tax benefits. The Fund has no examination in progress and is not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months.

The Fund will make distributions of net investment income monthly and net capital gains, if any, at least annually. Distributions to shareholders are recorded on the ex-dividend date. The amount and timing of distributions are determined in accordance with federal income tax regulations, which may differ from GAAP.

Pursuant to Rule 22e-4 under the 1940 Act, the Fund has adopted a Liquidity Risk Management Program (“LRMP”) that requires, among other things, that the Fund limits its illiquid investments that are assets to no more than 15% of net assets. An illiquid investment is any security which may not reasonably be expected to be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment. If the Advisor, at any time, determines that the value of illiquid securities held by the Fund exceed 15% of its NAV, the Advisor will take such steps as it considers appropriate to reduce them as soon as reasonably practicable in accordance with the Fund’s written LRMP.

ETFs typically trade on securities exchanges and their shares may, at times, trade at a premium or discount to their net asset values. In addition, an ETF 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, the temporary unavailability of certain index securities in the secondary market or discrepancies between the ETF and the index with respect to the weighting of securities or the number of securities held. Investing in ETFs, which are investment companies, may involve duplication of advisory fees and certain other expenses. As a result, Fund shareholders indirectly bear their proportionate share of these acquired expenses. Therefore, the cost of investing in the Fund will be higher than the cost of investing directly in ETFs and may be higher than other mutual funds that invest directly in securities.

The Trust, on behalf of the Fund, entered into an Investment Advisory Agreement (the “Agreement”) with the Adviser. Under the terms of the Agreement, the Fund pays a monthly investment advisory fee to the Adviser at the annual rate of 0.25% of the Fund’s average daily net assets.

The Adviser has contractually agreed to waive its fees and/or pay for operating expenses of the Fund to ensure that total annual fund operating expenses (excluding any leverage expense, brokerage fees and commissions, acquired fund fees and expenses, borrowing costs (such as interest and dividend expense on securities sold short), taxes, and extraordinary expenses, such as litigation expenses), do not exceed 0.09% of the Fund’s average daily net assets. This agreement is in effect until October 31, 2027, and it may be terminated before that date only by the Trust’s Board of Trustees. For the six months ended March 31, 2026, the Adviser waived advisory fees and reimbursed expenses totaling $82,520.

These expense reimbursements are subject to possible recoupment by the Adviser from the Fund (within three years) if such recoupment can be achieved within the lesser of the foregoing expense limits and the expense limits in place at time of recoupment. This agreement may be terminated by the Board only on 60 days’ written notice to the Adviser. The potential recoverable amount is noted as “Commitments and contingencies” as reported on the Statement of Assets and Liabilities. As of March 31, 2026, the Adviser may seek recoupment for previously waived or reimbursed expenses, subject to the limitations noted above, no later than the dates as outlined below:

Brown Brothers Harriman & Co. (“BBH”) serves as the Fund’s fund accountant, transfer agent, and custodian. UMB Fund Services, Inc. (“UMBFS”) serves as the Fund’s co-administrator; and Mutual Fund Administration, LLC (“MFAC”) serves as the Fund’s other co-administrator. The Fund’s allocated fees incurred for fund accounting, fund administration, transfer agency and custody services for the six months ended March 31, 2026 are reported as “Fund services fees” on the Statement of Operations.

Distribution Services, LLC, serves as the Fund’s distributor (the “Distributor”). The Distributor does not receive compensation from the Fund for its distribution services; The Adviser pays the Distributor a fee for its distribution-related services.

Certain trustees and officers of the Trust are employees of UMBFS, MFAC or the Adviser. The Fund does not compensate trustees and officers affiliated with the Fund’s Adviser or co-administrators. For the six months ended March 31, 2026, the Fund’s allocated fees incurred to Trustees of the Trust who are not “interested persons” of the Trust, as that term is defined in the 1940 Act (collectively, the “Independent Trustees”) are reported on the Statement of Operations.

At March 31, 2026, gross unrealized appreciation and depreciation on investments owned by the Fund, based on cost for federal income tax purposes were as follows:

The difference between cost amounts for financial statement and federal income tax purposes is due primarily to timing differences in recognizing certain gains and losses in security transactions.

For the six months ended March 31, 2026, purchases and sales of investments, short-term investments, were $7,359,404 and $4,954,390, respectively.
