NOTES TO FINANCIAL STATEMENTS

April 30, 2024 (Unaudited)

Note 1 - Organization

Vaughan Nelson Emerging Markets Fund (the "Emerging Markets Fund") and Vaughan Nelson International Fund (the "International Fund"), each a "Fund" and collectively the ''Funds'') are organized as a series of Investment Managers Series Trust, a Delaware statutory trust (the "Trust") which is registered as an open-end management investment company under the Investment Company Act of 1940, as amended (the "1940 Act"). The Vaughan Nelson Funds are diversified funds. The Emerging Markets Fund and International Fund's primary investment objective is to provide long-term capital appreciation. Prior to March 1, 2024, Vaughan Nelson Emerging Markets Fund and Vaughan Nelson International Fund were known as Vaughan Nelson Emerging Markets Opportunities Fund and Vaughan Nelson International Small Cap Fund.

The Emerging Markets Fund offers two classes of shares, Institutional Class shares and Investor Class shares. Institutional Class shares commenced operations on November 1, 2013. Investor Class shares commenced operations on December 2, 2019.

The International Fund offers two classes of shares, Institutional and Investor. Institutional Class shares commenced operations on December 31, 2013. Advisor Class shares converted into Institutional Class shares on February 10, 2020. The Investor Class shares commenced operations on December 2, 2019.

The shares of each class represent an interest in the same portfolio of investments of the International Fund and Emerging Markets Fund have equal rights as to voting, redemptions, dividends and liquidation, subject to the approval of the Trustees. Income, expenses (other than expenses attributable to a specific class) and realized and unrealized gains and losses on investments are allocated to each class of shares in proportion to their relative net assets. Shareholders of a class that bears distribution and service expenses under the terms of a distribution plan have exclusive voting rights to that distribution plan.

Each 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".

Note 2 - Accounting Policies

The following is a summary of the significant accounting policies consistently followed by the Funds 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.

(a) Valuation of Investments

Each 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 Advisor 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 Advisor has adopted and implemented policies and procedures to be followed when the Fund must utilize fair value pricing.

(b) Preferred Stocks

Preferred stocks are a class of stock having a preference over common stock as to the payment of dividends and the recovery of investment in the event a company is liquidated, although preferred stock is usually subordinate to the debt securities of the issuer. Preferred stock typically does not possess voting rights and its market value may change based on changes in interest rates. If interest rates rise, the fixed dividend on preferred stocks may be less attractive, causing the price of preferred stocks to decline. Preferred stock may have mandatory sinking fund provisions, as well as call/redemption provisions prior to maturity, a negative feature when interest rates decline.

(c) Exchange Traded Funds ("ETFs")

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. Each ETF in which each 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, and risks associated with fixed-income securities.

(d) Investment Transactions, Investment Income and Expenses

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 Funds record 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.

(e) Foreign Currency Translation

The Funds' 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 at the close of the London Stock Exchange prior to when the Funds' NAV is next determined. Purchases and sales of investment securities, income and expenses are translated on the respective dates of such transactions.

Vaughan Nelson Funds

NOTES TO FINANCIAL STATEMENTS - Continued

April 30, 2024 (Unaudited)

The Funds do not isolate that portion of their 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 Funds' 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.

(f) Federal Income Taxes

The Funds intend 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 Funds.

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 Funds' 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 Funds recognize interest and penalties, if any, related to unrecognized tax benefits as income tax expense in the Statements of Operations.

The Income Tax Statement requires management of the Funds to analyze tax positions taken in the prior three open tax years, if any, and tax positions expected to be taken in the Funds' 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 and during the open years ended October 31, 2021 - 2023 and the six months ended April 30, 2024, the Funds did not have a liability for any unrecognized tax benefits. The Funds have no examination in progress and are 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.

(g) Distributions to Shareholders

The Funds will make distributions of net investment income 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.

(h) Illiquid Securities

Pursuant to Rule 22e-4 under the 1940 Act, the Funds have adopted a Liquidity Risk Management Program ("LRMP") that requires, among other things, that the Funds limit their 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 a Fund exceeds 15% of its net asset value, the Advisor will take such steps as it considers appropriate to reduce them as soon as reasonably practicable in accordance with the Funds' written LRMP.

Note 3 - Investment Advisory and Other Agreements

The Trust, on behalf of the Funds, entered into an investment advisory agreement (the "Advisory Agreement") with Vaughan Nelson Investment Management, L.P. (the "Advisor"). Under the terms of the Agreement, the Funds pay a monthly investment advisory fee to the Advisor at the following annual rates based on the average daily net assets of the Funds:

Emerging Markets Fund	0.85%*
International Fund	0.75%+

*	Prior to March 1, 2024, annual rate of the investment advisory fee was 0.95%.

+	Prior to March 1, 2024, annual rate of the investment advisory fee was 0.85%.

The Advisor has contractually agreed to waive its fee and/or pay for operating expenses of the Funds to ensure that total annual operating expenses (excluding any taxes, leverage interest, brokerage commissions, dividend and interest expenses on short sales, acquired fund fees and expenses (as determined in accordance with Form N-1A) professional fees related to services for the collection of foreign tax reclaims, expenses incurred in connection with any merger or reorganization, and extraordinary expenses such as litigation expenses) do not exceed the following levels:

Expense Limit as a % of average daily net assets
Emerging Markets Fund - Investor Class	1.25%*
Emerging Markets Fund - Institutional Class	1.00%*
International Fund - Investor Class	1.14%+
International Fund - Institutional Class	0.89%+

*	Prior to March 1, 2024, the annual operating expense limit for Emerging Markets Fund was 1.35% for Investor Class and 1.10% for Institutional Class.

+	Prior to March 1, 2024, the annual operating expense limit for International Fund was 1.24% for Investor Class and 0.99% for Institutional Class.

This agreement is in effect until March 1, 2025, and it may be terminated before that date only by the Trust's Board of Trustees. The Advisor waived its advisory fees and absorbed other expenses for the six months ended April 30, 2024 as stated below:

Emerging Markets Fund			$	135,526
International Fund				130,921

The Advisor is permitted to seek reimbursement from each Fund, subject to certain limitations, of fees waived or payments made to the Fund for a period ending three full fiscal years after the date of the waiver or payment. This reimbursement may be requested from the Fund if the reimbursement will not cause the Fund's annual expense ratio to exceed the lesser of (a) the expense limitation amount in effect at the time such fees were waived or payments made, or (b) the expense limitation amount in effect at the time of the reimbursement. At April 30, 2024, the amount of these potentially recoverable expenses was $947,933 and $894,159, for the Emerging Markets Fund and International Fund, respectively. The potential recoverable amount is noted as "Commitments and contingencies" as reported on the Statement of Assets and Liabilities. The Advisor may recapture all or a portion of the following amounts no later than October 31, of the years stated below:

The Funds' allocated fees incurred for fund accounting, fund administration, transfer agency and custody services for the six months ended April 30, 2024, are reported on the Statements of Operations.

Natixis Distribution, LLC. serves as the Funds' distributor (the "Distributor"). The Distributor does not receive compensation from the Funds for its distribution services; the Advisor pays the Distributor a fee for its distribution-related services.

Certain trustees and officers of the Trust are employees of UMBFS or MFAC. The Funds do not compensate trustees and officers affiliated with the Funds' co-administrators. For the six months ended April 30, 2024, each Fund's allocated fees paid to Trustees who are not affiliated with the Funds' co-administrators are reported on the Statements of Operations.

The Funds' Board of Trustees had 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 select various fund(s) in the Trust in which their deferred accounts shall be deemed to be invested. If a trustee elects to defer payment, the Plan provides for the creation of a deferred payment account. The Funds' liability for these amounts is adjusted for market value changes in the invested fund(s) and remains a liability to the Funds until distributed in accordance with the Plan. The Trustees Deferred compensation liability under the Plan constitutes a general unsecured obligation of each 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 Statements of Operations.

Dziura Compliance Consulting, LLC provides Chief Compliance Officer ("CCO") services to the Trust. The Funds' allocated fees incurred for CCO services for the six months ended April 30, 2024, are reported on the Statements of Operations.

Note 4 - Federal Income Taxes

At April 30, 2024, gross unrealized appreciation (depreciation) on investments, based on cost for federal income tax purposes were as follows:

		Emerging Markets Fund			International Fund
Cost of Investments		$	34,837,308			$	26,443,143
Gross Unrealized Appreciation		$	7,626,152			$	667,342
Gross Unrealized Depreciation			(1,238,602	)			(1,621,315	)
Net Unrealized Appreciation/(Depreciation) on investments		$	6,387,550			$	(953,973	)

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.

At October 31, 2023, the Funds had capital loss carryforwards, which reduce the Funds' taxable income arising from future net realized gains on investments, if any, to the extent permitted by the Code, and thus will reduce the amount of distributions to shareholders which would otherwise be necessary to relieve the Funds of any liability for federal tax. Pursuant to the Code, the capital loss carryforwards will expire as follows:

			Not Subject to Expiration
			Short-Term			Long-Term			Total
Emerging Markets Fund			$	3,197,747			$	873,900			$	4,071,647
International Fund				11,316,670				3,646,942				14,963,612

As of October 31, 2023, the components of accumulated earnings (deficit) on a tax basis were as follows:

		Emerging Markets			International

Undistributed long-term capital gains			-				-

The Trust, on behalf of the Emerging Markets Fund and International Fund, has adopted a Shareholder Servicing Plan to pay a fee at an annual rate of up to 0.15% of average daily net assets attributed to each class shares of the Funds serviced by shareholder servicing agents who provide administrative and support services to their customers.

For the six months ended April 30, 2024, shareholder servicing fees incurred are disclosed on the Statements of Operations.

Note 8 - Distribution Plan

The Trust, on behalf of the Funds, has adopted a Distribution Plan (the "Plan") pursuant to Rule 12b-1 under the 1940 Act which allows each Fund to pay distribution fees for the sale and distribution of its Investor Class shares. The Plan provides for the payment of distribution fees at the annual rate of up to 0.25% of each Fund's average daily net assets attributable to Investor Class shares, payable to Natixis Distribution, LLC. Institutional Class shares are not subject to any distribution or administrative service fees under the plan.

For the six months ended April 30, 2024, for the Emerging Markets Fund and International Fund, distribution fees incurred by each Fund's Investor Class shares are disclosed on the Statements of Operations.

Note 9 - Indemnifications

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

Note 10 - Fair Value Measurements and Disclosure

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 each Fund's investments. These inputs are summarized into three broad Levels as described below:

●	Level 1 - Unadjusted quoted prices in active markets for identical assets or liabilities that the Fund has the ability to access.

●

Level 2 - Observable inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These inputs may include quoted prices for the identical instrument on an inactive market, prices for similar instruments, interest rates, prepayment speeds, credit risk, yield curves, default rates and similar data.

●	Level 3 - Unobservable inputs for the asset or liability, to the extent relevant observable inputs are not available, representing the Fund's own assumptions about the assumptions a market participant would use in valuing the asset or liability, and would be based on the best information available.

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 April 30, 2024, in valuing the Funds' assets carried at fair value:

Note 11 - Market Disruption and Geopolitical Risks

Certain local, regional or global events such as war, acts of terrorism, the spread of infectious illnesses and/or other public health issues, financial statement 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, 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.

Note 12- New Accounting Pronouncement and Regulatory Updates

Effective January 24, 2023, the SEC adopted rule and form amendments to require mutual funds and exchange-traded funds (ETFs) to transmit concise and visually engaging streamlined annual and semiannual reports to shareholders that highlight key information deemed important for retail investors to assess and monitor their fund investments. Other information, including financial statements, will no longer appear in the funds' streamlined shareholder reports but must be available online, delivered free of charge upon request, and filed on a semiannual basis on Form N-CSR. The rule and form amendments have a compliance date of July 24, 2024. At this time, management is evaluating the impact of these rule and form amendment changes on the content of the current shareholder report and the newly created annual and semiannual streamlined shareholder reports.

Note 13 - Events Subsequent to the Fiscal Period End

The Funds have 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 Funds' related events and transactions that occurred through the date of issuance of the Funds' financial statements.

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

EXPENSE EXAMPLES

For the Six Months Ended April 30, 2024 (Unaudited)

Expense Examples

As a shareholder of the Funds, you incur two types of costs: (1) transaction costs, and (2) ongoing costs, including management fees; distribution and/or service (12b-1) fees (Investor Class only); and other Fund expenses. The examples below are intended to help you understand your ongoing costs (in dollars) of investing in the Funds and to compare these costs with the ongoing costs of investing in other mutual funds.

These investments are based on an investment of $1,000 invested at the beginning of the period and held for the entire period from November 1, 2023 to April 30, 2024.

Actual Expenses

The information in the row titled "Actual Performance" of the table below provides actual account values and actual expenses. You may use the information in these columns, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the appropriate row, under the column titled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The information in the row titled "Hypothetical (5% annual return before expenses)" of the table below provides hypothetical account values and hypothetical expenses based on the Funds' actual expense ratios and an assumed rate of return of 5% per year before expenses, which is not the Funds' actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Funds and other funds. To do so, compare these 5% hypothetical examples with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as redemption fees. Therefore, the information in the row titled "Hypothetical (5% annual return before expenses)" is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

Vaughan Nelson Emerging Markets Fund	Beginning Account Value	Ending Account Value	Expenses Paid During Period*
11/1/23	4/30/24	11/1/23 - 4/30/24
Investor Class	Actual Performance	1,000.00	1,123.50	6.96

	Hypothetical (5% annual return before expenses)	1,000.00	1,019.58	5.34

*

Expenses are equal to the Fund's annualized expense ratio of 1.31% and 1.06% for the Investor and Institutional Class shares, multiplied by the average account value over the period, multiplied by 182/366 (to reflect the six month period). The expense ratios reflect an expense waiver. Assumes all dividends and distributions were reinvested.
