Investment Goal

Aristotle Small/Mid Cap Equity Fund (the "Fund") seeks long-term capital appreciation.

Fees and Expenses of the Fund

The tables that follow describe the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and examples below. If these fees were included, the fees and expenses shown would be higher. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $100,000 in Class A shares of eligible Funds of the Trust. More information about these and other discounts is available from your financial professional and in the Overview of the Share Classes section on page 116 in the Fund's prospectus (the "Prospectus") and in the appendix to this Prospectus titled Variations in Sales Charge Waivers and Discounts Available Through Specific Financial Intermediaries .

1			The Management Fee consists of an Advisory Fee and a Supervision and Administration Fee paid to Aristotle Investment Services, LLC. The Advisory Fee is borne by the Fund at the same annual rate for all share classes of 0.65% of the average net assets. The Supervision and Administration Fee is borne separately by each class at an annual rate of 0.25% for Class A, Class C and Class I-2 and 0.20% for Class I of the net average assets of the class.
2			"Other Expenses" include securities litigation service fees of 0.01%, which are borne directly by the Fund.
3			Acquired Fund Fees and Expenses are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies. As such, they are not reflected in the total annual operating expenses in the Fund's financial statements. Acquired Fund Fees and Expenses have been estimated based on expected allocations to underlying funds.

Examples

The examples are intended to help you compare the cost of investing in the Fund with the cost of investing in other Funds of the Trust or other mutual funds. Each Example assumes that you invest $10,000 in the noted share class of the Fund for the time periods indicated, that your investment has a 5% return each year, and that the Fund's annual operating expenses remain as stated in the previous table for the time periods shown, except for the ten-year amounts for Class C shares that reflect the conversion to Class A shares six years after the end of the calendar month in which the shares were purchased and the fee waiver which is only reflected for the contractual periods. Although your actual costs may be higher or lower, the examples show what your costs would be based on these assumptions.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its holdings). For the fiscal year ended March 31, 2026, the portfolio turnover rate of the Fund was 26% of the average value of the Fund. A higher portfolio turnover rate reflects a greater number of securities being bought or sold, which 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 Examples , affect the Fund's performance.

Principal Investment Strategies

The Fund seeks to achieve its investment goal by investing, under normal circumstances, at least 80% of its net assets in equity securities of small-capitalization and mid-capitalization companies. Exchange-traded funds ("ETFs") that have adopted a policy of investing at least 80% of their net assets in such investments are treated as such investments for purposes of this 80% policy. The Fund's sub-adviser defines a small-cap italization and mid-cap italization company as one that, at the time of initial purchase, has a market capitalization that falls within the capitalization range of the Russell 2500 ® Index, which measures the performance of the small- to mid-capitalization segment of the U.S. equity universe. The Russell 2500 ® Index is reconstituted semi-annually. Because small and medium capitalization companies are defined by reference to an index, the range of market capitalization of companies in which the Fund invests may vary with market conditions. As of March 31, 2026 the smallest market capitalization in the Russell 2500 ® Index was $1.2 billion, while the largest market capitalization was $90.7 billion. Investments in companies that move above or below the capitalization range may continue to be held by the Fund at the sub-adviser's sole discretion , consistent with the Fund's 80% investment policy described above and applicable regulatory requirements . The Fund's investments in equity securities may include common stocks, depositary receipts, real estate investment trusts ("REITs") and exchange-traded funds ("ETFs") that invest primarily in equity securities of small- and medium-capitalization companies.

Depositary receipts represent interests in foreign securities held on deposit by banks. ETFs in which the Fund invests are investment companies that invest in portfolios of securities designed to track particular market segments or indices, the shares of which are bought and sold on securities exchanges. The Fund may lend its portfolio securities to generate additional income.

The Fund seeks to meet its investment goal by investing primarily in equity securities of U.S. issuers but may invest up to 5% of its total assets in American Depositary Receipts ("ADRs"). ADRs are receipts that represent interests in foreign securities held on deposit by U.S. banks.

In pursuing the Fund's investment goal, the sub-adviser employs a fundamental, bottom-up research driven approach to identify companies for investment by the Fund. The sub-adviser focuses on those companies that it believes have high-quality businesses that are undervalued by the market relative to what the sub-adviser believes to be their fair value. The sub-adviser seeks to identify high-quality businesses by focusing on companies that it believes have the following attributes: disciplined business plans; attractive business fundamentals; sound balance sheets; financial strength; experienced, motivated company management; reasonable competition; and/or a record of long-term value creation.

The Fund is benchmarked to the Russell 2500® Index for the purpose of performance measurement. However, the sub-adviser is not constrained by the composition of the index in selecting investments for the Fund.

Principal Risks

As with any mutual fund, the value of the Fund's investments, and therefore the value of your shares, may go up or down and you could lose money. There is no guarantee that the Fund will achieve its investment goal. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Italicized terms refer to separate Principal Risks that are each defined in the Principal Risks section below.

While the Fund may be subject to various risk exposures at any given time depending on market conditions and other factors impacting holdings and investment strategies, the Fund under normal circumstances is subject to the following principal risks:

•Equity Securities Risk: Equity securities tend to go up and down in value, sometimes rapidly and unpredictably. An equity security's market value may decline for a number of reasons that relate to particular issuer, such as management performance, financial leverage, reduced demand for the issuer's products or services, or as a result of factors that affect the issuer's industry or market more broadly, such as labor shortages, increased production costs, or competitive conditions within an industry.

•Mid-Capitalization Companies Risk: Mid-capitalization companies may be subject to greater price volatility and may be more vulnerable to economic, market and industry changes than larger, more established companies.

•Small-Capitalization Companies Risk: Small-capitalization companies may be more susceptible to liquidity risk and price

volatility and be more vulnerable to economic, market and industry changes than larger, more established companies.

• ETF Risk: Shares of ETFs typically trade on securities exchanges and may at times trade at a premium or discount to their net asset values. If the Fund has to sell shares of an ETF when the shares are trading at a discount, the Fund will receive a price that is less than the ETF's net asset value per share. In addition, an ETF may not replicate exactly the performance of the benchmark index it seeks to track. An investment in an ETF is an investment in another investment company and therefore, the Fund's shareholders will indirectly bear a proportionate share of any fees and expenses of the ETFs in which the Fund invests. The Fund will pay brokerage commissions in connection with the purchase and sale of shares of ETFs.

•Sector Focus Risk: The Fund may invest a larger portion of its assets in one or more sectors than many other mutual funds, and thus will be more susceptible to negative events affecting those sectors.

• REIT Investment Risk: Investments in REITs involve unique risks. REITs may have limited financial resources, may trade less frequently and in limited volume, and may be more volatile than other securities. REITs may be affected by changes in the value of their underlying properties or mortgages or by defaults by their borrowers or tenants. Furthermore, these entities depend upon specialized management skills, have limited diversification and are, therefore, subject to risks inherent in financing a limited number of projects. In addition, the performance of a U.S. REIT may be affected by changes in the tax laws or by its failure to qualify for tax-free pass-through of income.

•Active Management Risk: A portfolio manager's judgments about the potential value or price appreciation of an investment may prove to be incorrect or fail to have the intended results, which could negatively impact the Fund's performance.

•Liquidity Risk: Certain holdings may be difficult to purchase, sell and value, particularly during adverse market conditions, because there is a limited market for the investment or there are restrictions on resale. The Fund may invest in liquid investments that become illiquid due to financial distress, or geopolitical events such as sanctions, trading halts or wars. The Fund may not be able to sell a holding quickly at the price it has valued the holding, may be unable to take advantage of market opportunities or may be forced to sell other more desirable, more liquid securities or sell less liquid or illiquid securities at a loss if needed to raise cash to conduct operations, including to meet redemption requests. This risk may be particularly pronounced with respect to small-capitalization companies.

•Value Companies Risk: Value companies are those that a portfolio manager believes are undervalued and trading for less than their intrinsic values. There is a risk that the determination that a stock is undervalued is not correct or is not recognized in the market.

•Securities Lending Risk: To the extent the Fund lends its securities, it may be subject to the following risks: (1) the securities in which the collateral is invested may not perform sufficiently to cover the applicable rebate rates paid to borrowers

and related administrative costs; (2) delays may occur in the recovery of securities from borrowers, which could interfere with the Fund's ability to vote proxies or to settle transactions; and (3) although borrowers of the Fund's securities typically provide collateral in the form of cash that is reinvested in securities, there is the risk of possible loss of rights in the collateral should the borrower fail financially.

Performance

The bar chart and Average Annual Total Returns table below provide some indication of the risk of investing in the Fund by showing changes in the performance of the Fund from year to year and showing how the Fund's returns compare to a broad-based market index and a more focused benchmark. The Fund performance shown below for periods prior to April 17, 2023 is the performance of Pacific Funds Small/Mid Cap (the "Predecessor Fund"), a series of Pacific Funds Series Trust, as a result of a reorganization of the Predecessor Fund into the Fund on April 17, 2023 (the "Reorganization"). The Predecessor Fund was managed using investment policies, objectives, and guidelines that were different compared to those of the Fund, and investment restrictions that were substantially similar to those of the Fund. Prior to the Reorganization, the Fund had not yet commenced operations. The Predecessor Fund acquired the assets of the Rothschild U.S. Small/Mid-Cap Core Fund (the "First Predecessor Fund") in a reorganization transaction on January 11, 2016. The Predecessor Fund's objectives (goals), policies, guidelines and restrictions are substantially the same as those of the First Predecessor Fund.

The bar chart shows the performance of the Predecessor Fund's Class I-2 shares from inception through April 16, 2023 and the performance of the Fund's Class I-2 shares from April 17, 2023 through December 31, 2025. The performance figures shown below for the share classes of the Fund for periods prior to January 11, 2016, reflect the historical performance of the then-existing Institutional Class shares of the First Predecessor Fund. The performance figures for periods prior to January 11, 2016, have not been adjusted to reflect fees and expenses of Class A, Class C, Class R6, and Class I-2 shares of the Predecessor Fund, respectively. If these returns had been adjusted, then performance for the share classes would be lower than the returns shown based on differences in their fee and expense structures. The Institutional Class shares of the First Predecessor Fund commenced operations on December 31, 2014.

Prior to the reorganization with the Predecessor Fund, Great Lakes Advisors, LLC served as the sub-adviser to the Predecessor Fund, replacing Rothschild & Co Asset Management US Inc., which previously served as sub-adviser to the Predecessor Fund since its inception. Aristotle Capital Boston, LLC is the sub-adviser to the Fund and employs a different investment approach than the Predecessor Fund's sub-advisers. If the Fund's current sub-adviser and strategies had been in place for periods prior to April 17, 2023, the performance information shown below would have been different.

Performance reflects fee waivers or expense limitations, if any, that were in effect during the periods presented. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Sales charges are not reflected in the bar chart

and, if those charges were included, returns would be less than those shown. Updated performance information may be obtained at our website: aristotlefunds.com, or by calling customer service at 844-ARISTTL (844-274-7885).

The after-tax returns (a) are calculated using the highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes; (b) are shown for the Predecessor Fund's Class I-2 shares only and will vary for classes of the Fund; and (c) are not relevant to investors who hold their shares through tax-advantaged arrangements, such as 401(k) plans or individual retirement accounts. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. In some instances, the return after taxes on distributions and sale of Fund shares may be greater than the return before taxes because the investor is assumed

to be able to use the capital loss of the sale of Fund shares to offset other taxable capital gains.
