**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 (expense limitation) 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, which operates as a "fund of funds" that seeks to achieve its investment goal by investing in unaffiliated exchange-traded funds ("ETFs") and in other funds organized as series of the Trust (collectively, the "Underlying Funds"), does not pay transaction costs, such as commissions, when it buys and sells shares of Underlying Funds (or "turns over" its holdings); however, a higher portfolio turnover rate, which reflects a greater number of shares of Underlying Funds being bought or sold, may result in higher taxes when Fund shares are held in a taxable account. For the fiscal year ended March 31, 2025, the portfolio turnover rate of the Fund was 53% of the average value of the Fund. An Underlying Fund typically does pay transaction costs when it turns over its portfolio so a higher portfolio turnover rate, which reflects a greater number of securities being bought or sold, may indicate higher transaction costs and may result in higher taxes to Fund shareholders who hold Fund shares in a taxable account. These costs, which are not reflected in *Annual Fund Operating Expenses* or in the *Examples* , affect the Fund's and Underlying Funds' performance.

**Principal Investment Strategies**

This Fund is a "fund of funds" that seeks to achieve its investment goal by investing in a combination of Underlying Funds, including funds that are actively managed by an affiliate of the investment adviser and unaffiliated ETFs, including passively managed funds that seek to track the performance of a benchmark index. The allocation of the Fund's assets between Underlying Funds sub-advised by an affiliate of the investment adviser and unaffiliated ETFs will vary over time, although the sub-adviser currently expects to invest, under normal circumstances, between 40% and 90% of the Fund's assets in Underlying Funds sub-advised by an affiliate of the investment adviser. Under normal market conditions, the Fund's exposures to the two broad asset classes of debt and equity are expected to be within the following ranges:

---

| | |
|:---|:---|
| **BROAD ASSET CLASS ALLOCATIONS** | **BROAD ASSET CLASS ALLOCATIONS** |
| **<u>Debt</u>** | **<u>Equity</u>** |
| 70-85% | 15-30% |

---

The sub-adviser to the Fund manages the investment program for the Fund through a multi-step process that includes:

&nbsp;&nbsp;&nbsp;&nbsp;**(1) Asset Allocation/Portfolio Construction**—The sub-adviser manages the Fund using an approximate 10-year investment horizon. An asset class model (the "Model") for the Fund is developed that seeks to meet the Fund's investment goal over this period using both equity and debt asset classes. The equity asset class includes narrower asset classes such as domestic small-capitalization, mid-capitalization and large-capitalization, growth and value strategies, and international equities. The debt asset class also includes narrower asset classes such as investment grade bonds, high yield/high risk bonds, bank loans, international debt and emerging market debt.

The sub-adviser then determines the amount of the Fund's assets to invest in each Underlying Fund in order to obtain the asset class exposures designated by the Model for the Fund.

The sub-adviser may adjust the broad asset class allocations to any point within the above ranges, and/or adjust the narrower asset class allocations, or the allocations to the Underlying Funds, at any time as it deems necessary based on the sub-adviser's views of market conditions, its outlook for various asset classes or other factors that it determines are relevant in seeking to achieve the Fund's investment goal ("dynamic positioning").

For example, the sub-adviser may engage in dynamic positioning for the Fund by adjusting the Model to reflect a shorter-term view of the markets or a particular asset class, to seek to capture upside opportunities or mitigate risk from market events, or for cash management purposes. The sub-adviser would then make the appropriate adjustments to its Underlying Funds allocations to reflect the updated asset class allocations in the Model. This dynamic positioning would be implemented consistent with the Fund's risk/return profile and investment goal.

&nbsp;&nbsp;&nbsp;&nbsp;**(2) Investment Risk Management**—The sub-adviser monitors and analyzes the investment risks of the Fund, evaluates their impact on the Fund's risk/return objectives and considers adjustments to the Fund's allocations as a result.

Investments of the Underlying Funds that invest primarily in debt instruments include investment grade debt securities, including U.S. Government securities, corporate bonds, mortgage-related securities, and other asset-backed securities; foreign debt securities, including emerging market debt; debt instruments of varying duration; convertible securities; high yield/high risk bonds; floating rate loans; and inflation-indexed bonds.

Investments of the Underlying Funds that invest primarily in equity instruments include growth and value stocks; large-, mid- and small-capitalization companies; sector-specific stocks; preferred stock; warrants and rights; and domestic and foreign stocks, including emerging market stocks. Underlying Funds that operate as passively managed index funds may invest directly in the component securities of the benchmark index or may seek to replicate the performance of the benchmark index through index sampling.

------

The Fund is expected to be as fully invested as practical, although it may maintain liquidity reserves to meet redemption requests.

The Fund may lend its portfolio securities to generate additional income.

The Fund may invest a significant portion of its assets in any single Underlying Fund. The sub-adviser has sole discretion in selecting the Underlying Funds for investment and may adjust the Fund's allocations to the Underlying Funds, and add or remove Underlying Funds as it deems appropriate to meet the Fund's investment goal.

For additional information about the Fund and its Underlying Fund investments, please see the *Additional Information About Principal Investment Strategies and Principal Risks* section in the Prospectus.

**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. Because this Fund has a significant portion of its assets invested in Underlying Funds that invest primarily in debt instruments, this Fund has more exposure to *debt securities risk* than other Portfolio Optimization Funds. 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.

As a "fund of funds," the Fund is subject to *Asset Allocation Fund of Funds Risk, Conflicts of Interest Risk, ETF Risk and Securities Lending Risk* . The Fund is also subject to the risks of the Underlying Funds in which it invests, which may change based on the Fund's allocations to the Underlying Funds. The principal risks to the Fund from these Underlying Fund investments are described below.

• **Asset Allocation Fund of Funds Risk:** Asset allocation decisions, techniques, analyses, or models implemented by the sub-adviser may not produce the expected returns, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment goals. Although the theory behind asset allocation is that diversification among asset classes can help reduce volatility over the long term, you still may lose money and/or experience price volatility. Performance of and the sub-adviser's assumptions about asset classes and Underlying Funds may diverge from historical performance and assumptions used to develop allocations in light of actual market conditions. There is a risk that you could achieve better returns by investing in an individual fund or funds representing a single asset class rather than investing in a fund of funds. The Fund's performance is also closely related to the Underlying Funds' performance and ability to meet their investment goals. Fund shareholders bear indirectly the expenses of the Underlying Funds in which the Fund invests in addition to the Fund's management fee so there is a risk of an additional layer or layers of fees. The Fund's actual asset class allocations may deviate from the intended allocation because an Underlying Fund's investments can change due to market movements, the Underlying Fund Manager's investment decisions or other factors, which could result in the fund's risk/return target not being met. As a fund of funds, the Fund is exposed to the same risks as the Underlying Funds in proportion to the Fund's

allocation to those Underlying Funds. To the extent that the Fund invests a significant portion of its assets in a single Underlying Fund, it may be more susceptible to risks associated with that fund and its investments.

• **Conflicts of Interest Risk:** The investment adviser and sub-adviser are subject to competing interests that have the potential to influence investment decisions for the Fund. For example, an Underlying Fund managed by an affiliate of the sub-adviser or the investment adviser or that provides greater profitability than another Underlying Fund may create an incentive for the sub-adviser to use that fund as an Underlying Fund. In addition, the sub-adviser may be influenced by its or the investment adviser's view of the best interests of Underlying Funds, such as a view that an Underlying Fund may benefit from additional assets or could be harmed by redemptions. The sub-adviser seeks to identify and address any potential conflicts in a manner that is fair for Underlying Funds, the Fund and the shareholders of the Fund and Underlying Fund. The sub-adviser has adopted a policy under which investment decisions for the Fund must be made in the best interests of the Fund and its shareholders, and the sub-adviser may take into account the interests of an Underlying Fund and its shareholders when making investment decisions for the Fund.

• **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.

• **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.

**Principal Risks from Holdings in Underlying Funds**

• **Debt Securities Risk:** Debt securities and other debt instruments are subject to many risks, including *interest rate risk* and *credit risk*, which may affect their value. The market value of a fixed-income security may decline due to general market conditions that are not specifically related to a particular company. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Federal Reserve policy in response to market conditions may adversely affect the value, volatility and liquidity of debt securities.

------

• **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.

• **Interest Rate Risk:** The value of debt instruments may fall when interest rates rise. Debt instruments with longer durations tend to be more sensitive to changes in interest rates, making them more volatile than debt instruments with shorter durations or floating or adjustable interest rates. During periods when interest rates are low or there are negative interest rates, the Fund's yield (and total return) also may be low, and the Fund may experience low or negative returns. During periods when the Federal Reserve raises interest rates, the Fund may be subject to heightened levels of interest rate risk. As interest rates rise, the value of fixed income investments will generally decrease.

• **Credit Risk:** An issuer or guarantor of a debt instrument might be unable or unwilling to meet its financial obligations and might not make interest or principal payments on an instrument when those payments are due ("default"). The risk of a default is higher for debt instruments that are non-investment grade and lower for debt instruments that are of higher quality. Defaults may potentially reduce the Fund's income or ability to recover amounts due and may reduce the value of the debt instrument, sometimes dramatically.

• **U.S. Government Securities Risk:** Not all U.S. government securities are backed or guaranteed by the U.S. government and different U.S. government securities are subject to varying degrees of *credit risk* . There is a risk that the U.S. government will not make timely payments on its debt or provide financial support to U.S. government agencies, instrumentalities, or sponsored enterprises if those entities are not able to meet their financial obligations.

• **Mortgage-Related and Other Asset-Backed Securities Risk:** Mortgage-related and other asset-backed securities, including collateralized loan obligation transactions ("CLOs"), are subject to certain risks affecting the housing market, the market for the assets underlying such securities or the issuers of such securities. These securities may also be subject to extension risk (the risk that rising interest rates extend the duration of fixed mortgage-related and other asset-backed securities, making them more sensitive to changes in interest rates), interest rate risk (the risk that rising interest rates will cause a decline in the value of a fixed income security), subprime risk or credit risk (the risk that mortgage-related and other asset-backed securities have exposure to borrowers with lower credit ratings/scores, increasing potential default), prepayment risk (when interest rates decline, borrowers may pay off their mortgages or debt obligations sooner than expected which can reduce the Fund's returns because the Fund may have to reinvest its assets at lower interest rates), call risk (similar to prepayment risk, an issuer may pay its obligations under a security sooner than expected), U.S. government securities risk (securities backed by different U.S. government agencies, if

applicable, are subject to varying levels of credit rating risk) and issuer risk (the risk that a private issuer cannot meet its obligations).

• **High Yield/High Risk or "Junk" Securities Risk:** High yield/high risk securities are typically issued by companies that are highly leveraged, less creditworthy, or financially distressed and are considered to be mostly speculative in nature (high risk), subject to greater *liquidity risk* , and subject to a greater risk of default than higher rated securities. High yield/high risk securities (including loans) may be more volatile than investment grade securities.

• **Floating Rate Loan Risk:** Floating rate loans (or bank loans) are usually rated below investment grade and thus are subject to high yield/high risk or "junk" securities risk. The market for floating rate loans is a private interbank resale market and thus may be subject to irregular trading activity, wide bid/ask spreads and delayed settlement periods. Purchases and sales of loans are generally subject to contractual restrictions that must be fulfilled before a loan can be bought or sold. These restrictions may hamper the Fund's ability to buy or sell loans and negatively affect the transaction price. Prices of below investment grade loans are also more volatile, are more sensitive to negative news about the economy or the issuer, and have greater liquidity risk and price volatility. The value and the income streams of interests in loans (including participation interests in lease financings and assignments in secured variable or floating rate loans) will decline if borrowers delay payments or fail to pay altogether. A significant rise in market interest rates could increase this risk. Although loans may be fully collateralized when purchased, such collateral may become illiquid or decline in value.

A significant portion of the floating rate loans held by the Fund may be "covenant lite" loans that contain fewer or less restrictive constraints on the borrower or other borrower-friendly characteristics and offer less protections for investors than covenant loans.

It may take longer than seven days for transactions in loans to settle. This may result in cash proceeds not being immediately available to the Fund, requiring the Fund to borrow cash which would increase the Fund's expenses. The Fund is also subject to credit risk with respect to the issuer of the loan, and an issuer's long-term ability to make payments on below investment grade loans is considered speculative. Investments in junior loans involve a higher degree of overall risk.

U.S. federal securities laws afford certain protections against fraud and misrepresentation in connection with the offering or sale of a security, as well as against manipulation of trading markets for securities. However, it is unclear whether these protections are available to an investment in a loan.

• **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.

------

• **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.

• **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.

• **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.

• **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. 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.

• **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.

• **Currency Risk:** A decline in the value of a foreign currency relative to the U.S. dollar reduces the value in U.S. dollars of the Fund's investments denominated in or with exposure to that foreign currency.

• **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.

• **Passive Management Risk:** A passively managed (or index) fund generally holds constituent securities of its benchmark index regardless of performance, which could cause the index fund's return to be lower than an actively managed fund (which generally seeks to outperform a benchmark index). Such fund will also perform poorly when the index performs poorly. In addition, an index fund has operating and other expenses while an index does not. As such, an index fund will tend to underperform the index to some degree over time even though it will attempt to track its index as closely as possible.

• **Index Sampling Risk:** Because index sampling relies on the securities selected to have economic characteristics similar to securities in the fund's benchmark index, it may not result in the aggregate in investment performance matching that of that fund's benchmark index or of other funds that purchased all or substantially all of the securities in the same index in approximately the same proportions as their weightings in the index.

• **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. Further, the lack of an established secondary market for floating rate loans may make it more difficult to value illiquid loans, exposing the Fund to the risk that the price at which it sells loans will be less than the price at which they were valued when held by the Fund.

• **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.

• **Financial Sector Risk:** The operations and businesses of financial services companies are subject to extensive governmental regulation, the availability and cost of capital funds, and interest rate changes. General market downturns may affect financial services companies adversely.

------

• **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.

• **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.

• **Industry Concentration Risk:** In order to track the composition of the index for which it seeks corresponding investment results, a passively managed Underlying Fund may invest a greater percentage of its assets in a particular industry or group of industries, making that Underlying Fund more susceptible to adverse economic, business, regulatory or other developments affecting that industry or group of industries, 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.

• **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.

**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 broad-based market indexes and a more focused benchmark. The Fund performance

shown below for periods prior to April 17, 2023 is the performance of Pacific Funds Portfolio Optimization Conservative (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, guidelines, and restrictions that were substantially similar to those of the Fund. Prior to the Reorganization, the Fund had not yet commenced operations. The bar chart shows the performance of the Predecessor Fund's Class A shares from inception through April 16, 2023 and the performance of the Fund's Class A shares from April 17, 2023 through December 31, 2024.

Sales charges applicable to Predecessor Fund's Class A shares are reflected in the Average Annual Total Returns table but not in the bar chart. If these charges were reflected in the bar chart, returns would be lower than those shown. 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.

<sup>1</sup> The broad-based market indexes for the Fund are the S&P 500 <sup>®</sup> Index and the Bloomberg US Aggregate Bond Index. The Fund is also benchmarked to a composite benchmark, the Aristotle Portfolio Optimization Conservative Composite Benchmark, for the purpose of performance measurement.

<sup>2</sup> The Aristotle Portfolio Optimization Conservative Composite Benchmark represents the blended performance of 71% Bloomberg US Aggregate Bond, 17% S&P 500 <sup>®</sup> , 7% ICE BofA U.S. 3-Month T-Bill, and 5% MSCI EAFE (net) Indices.

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 A 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.

**Purchase and Sale of Fund Shares**

Once you have established an account, you may generally purchase or redeem (sell) shares of a Fund (each a "Fund," together the "Funds") of the Aristotle Funds Series Trust ("Aristotle Funds" or the "Trust") on any business day by mail (Aristotle Funds, c/o U.S. Bank Global Fund Services, P.O. Box 219231, Kansas City, MO 64121-9231), overnight mail (Aristotle Funds, c/o U.S. Bank Global Fund Services, 801 Pennsylvania Ave, Suite 219231, Kansas City, MO 64105-1307), by telephone by calling customer services at 844-ARISTTL (844-274-7885) or by wire or electronic funds transfer. For accounts established through a broker-dealer or other financial intermediary, please contact your financial professional to purchase or redeem shares.

For Class A and Class C shares, the minimum initial investment is $1,000, and the minimum subsequent investment is $50. For Class I shares, the minimum initial investment is $500,000 for Institutional

Investors, with no minimum for subsequent investments. Class I shares are only available to eligible investors. Class R6 shares generally have no minimum for initial or subsequent investments, except for certain institutional investors who purchase Class R6 shares directly with the Trust's transfer agent for which the minimum initial investment is $1,000,000 with no minimum for subsequent investments. Class R6 shares are only available to eligible investors. No dealer compensation, marketing support payments, or sub-transfer agency fees are paid on Class I or Class R6 shares. There is no minimum initial or subsequent investment for Class I-2 shares, because they are generally only available to investors in fee-based advisory programs. Not all classes are available for direct investment for all Funds. The Trust reserves the right to waive or change minimum investment amounts at its discretion. The Trust and Foreside Financial Services, LLC, the distributor and principal underwriter for the Trust (the "Distributor"), reserve the right to reject any request to buy shares.

Purchase and sale orders for accounts held directly with the Trust are executed at the next-calculated net asset value ("NAV"), plus or minus any applicable sales charges, determined after the transfer agent of the Trust receives an order in proper form at its processing location in Milwaukee, WI. Purchase and sale orders for accounts held with a financial intermediary are executed at the next NAV, 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.
