Investment Goal

Aristotle Core Equity Fund (the "Fund") seeks long-term 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. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example 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 $50,000 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 the 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 0.50% of the average net assets. The Supervision and Administration Fee is borne separately by each class at an annual rate of 0.15% of the average net assets of the class.

Example

The Example is 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. The Example assumes that you invest $10,000 for the time periods indicated and redeem all of your shares at the end of those periods, 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. Although your actual costs may be higher or lower, the Example shows what your costs would be based on these assumptions.

Your expenses (in dollars) if you SELL or DON'T SELL your shares at the end of each period.
Share Class
			A			I			I-2
1 year			$513			$66			$66
3 years			$700			$208			$208
5 years			$902			$362			$362
10 years			$1,486			$810			$810

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 16% of the average value of its portfolio. 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 Example , 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. 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 investments in equity securities may include common stocks, preferred stocks, convertible preferred stocks, depositary receipts, shares of publicly traded real estate investment trusts ("REITs") and exchange-traded funds ("ETFs") that invest primarily in equity securities, warrants and rights. The Fund's investments in depositary receipts may include American, European, and Global Depositary Receipts ("ADRs," "EDRs," and "GDRs," respectively). ADRs are receipts that represent interests in foreign securities held on deposit by U.S. banks. EDRs and GDRs have the same qualities as ADRs, except that they may be traded in several international trading markets. Although the Fund may invest in companies of any market capitalization and from any country, the sub-adviser's investment process typically focuses on the universe of U.S. companies with market capitalizations in excess of $2 billion at initial investment. The Fund may lend its portfolio securities to generate additional income.

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 seeks to identify companies that it believes are positioned to benefit from one or more of the following: (i) shifts in industry spending, government spending and consumer trends; (ii) gains in market share from innovative products and strong intellectual property; and (iii) cyclical trends in the industry in which they operate and capable management that can take advantage of those trends. The investment process and allocation decisions result in a portfolio that blends both value and growth characteristics. At times, the Fund's assets may be invested in securities of relatively few industries or sectors.

The Fund is benchmarked to the S&P 500® Index for performance measurement purposes. However, the sub-adviser is not constrained by the composition of the S&P 500® 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.

•Large-Capitalization Companies Risk: Although large-capitalization companies tend to have more stable prices than smaller, less established companies, they are still subject to equity securities risk. In addition, large-capitalization equity security prices may not rise as much as prices of equity securities of small-capitalization 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.

•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.

•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.

•Information Technology Sector Risk: Information Technology companies face numerous risks, including operating in rapidly changing fields, abrupt or erratic market movements, limited product lines, markets or financial resources, management that is dependent on a limited number of people, short product cycles, aggressive pricing of products and services, new market entrants, government regulation and patent and intellectual property rights and rapid obsolescence of products and services due to technological innovations or changing consumer preferences. In addition, many U.S. technology companies have diverse operations, with products or services in foreign markets, exposing them to foreign investment risk. The information technology sector has recently experienced significant disruptions caused by artificial intelligence ("AI") related events, including layoffs and workforce re-alignments related to AI advancements and AI-related spending and escalating AI-enabled cyberattacks and data breaches. These events have led to significant market volatility and stock declines for certain software, cybersecurity, and other companies within this sector.

•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.

• Foreign Investment Risk: Exposure to a foreign market through investments in foreign issuers (companies or other entities) can involve additional risks relating to market, economic, political, regulatory, geopolitical, or other conditions of that market. These factors can make investments in foreign issuers more volatile and less liquid than U.S. investments. Trade disputes and the threat of, or actual imposition of, tariffs may adversely impact the price of foreign securities. Less stringent regulatory, accounting, and disclosure requirements and general supervision for issuers and markets are more common in certain foreign countries. Enforcing legal rights can be difficult, costly, and slow in certain foreign countries, and can be particularly difficult against foreign governments. In addition, foreign markets can react differently to these conditions than the U.S. market. Markets and economies throughout the world are becoming increasingly interconnected, and conditions or events in one market, country or region may adversely impact investments or issuers in, or foreign exchange rates with, another market, country, or region. Certain countries or regions may have economies that are heavily dependent upon trading with key partners; this reliance on trading partners may have an adverse impact on investments if there is a reduction in such trading. Foreign securities may include ADRs, EDRs and GDRs. Unsponsored ADRs, EDRs and GDRs are organized independently and without the cooperation of the foreign issuer of the underlying securities. In addition, the issuing bank may deduct shareholder distribution, custody, foreign currency exchange, and other fees from the payment of dividends.

•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.

•Warrants and Rights Risk: Warrants and rights may lack a liquid secondary market for resale. The prices of warrants and rights may fluctuate as a result of speculation or other factors. Warrants and rights can provide a greater potential for profit or loss than an equivalent investment in the underlying security. Prices of warrants and rights do not necessarily move in tandem with the prices of their underlying securities and therefore are highly volatile and speculative investments. If a warrant or right expires without being exercised, the Fund will lose any amount paid for the warrant or right.

•Preferred Stock Risk: Preferred stock represents an equity interest in a company that generally entitles the holder to receive, in preference to the holders of other stocks such as common stock, dividends and a fixed share of the proceeds resulting from a liquidation of the company. The market value of preferred stock is subject to company-specific and market risks applicable generally to equity securities and is also sensitive to changes in the company's creditworthiness, the ability of the company to make payments on the preferred stock, and changes in interest rates,

typically declining in value if interest rates rise. Convertible preferred stock allows the holder to convert the preferred shares into a fixed number of common shares, usually after a predetermined date. Like preferred stock, convertible preferred stock generally pays a dividend at a specified rate and has preference over common stock in the payment of dividends but ranks behind bonds, including convertible bonds, in priority upon liquidation.

•Emerging Markets Risk: Investments in or exposure to investments in emerging market countries may be riskier than investments in or exposure to investments in U.S. and other developed markets for many reasons, including smaller market capitalizations, greater price volatility, less liquidity, lower credit quality, a higher degree of political and economic instability, the imposition of economic sanctions, less governmental regulation and supervision of the financial industry and markets, and less stringent financial reporting and accounting standards and controls.

•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.

•Underlying Fund Risk: Because the Fund is available for investment by one or more "fund of funds" of the Trust and thus may have a significant percentage of its outstanding shares held by such fund of funds, a change in asset allocation by the fund of funds could result in large redemptions out of the Fund, causing the sale of securities in a short timeframe and potential increases in expenses to the Fund and its remaining shareholders, both of which could negatively impact performance.

•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. The Fund performance shown below for periods prior to October 23, 2023 is the performance of the Aristotle Core Equity Fund (the "Predecessor Fund"), a series of Investment Managers Series Trust, as a result of the reorganization of the Predecessor Fund into the Fund on October 23, 2023. The Predecessor Fund was managed by the same portfolio management team using investment policies, objectives, guidelines and restrictions that were substantially similar to those of the Fund. The bar chart shows the performance of the Predecessor Fund's Class I shares from inception through October 22, 2023 and the performance of the Fund's Class I-2 shares from October 23, 2023 through December 31, 2025.

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).

1 The broad-based market index and the performance measurement benchmark for the Fund is the S&P 500® Index.

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, and (b) 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.

Class I-2 shares commenced operations on March 31, 2017. Class A and Class I shares commenced operations on October 23, 2023 and October 20, 2013, respectively. Performance for Class A and Class I shares prior to their respective inception dates reflects the performance of Class I-2 shares adjusted for Class A and Class I shares expenses, respectively.

plus or minus any applicable sales charges, determined after the order is received by the financial intermediary in proper form.

Tax Information

Each Fund's distributions are taxable and will be taxed as ordinary income or capital gains, unless you are investing through a tax-advantaged arrangement such as a 401(k) plan or an individual retirement account, distributions from which may be taxable upon withdrawal.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase shares of a Fund through a broker-dealer or other financial intermediary (such as through a "fund supermarket" where a variety of mutual funds from different fund families are offered through your broker-dealer or other financial intermediary), the Trust and its related companies may pay the broker-dealer or other financial intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other financial intermediary and your salesperson to recommend the Fund over another investment. Ask your financial professional or visit your financial intermediary's website for more information.
