Investment Objective

The Brookfield Global Listed Infrastructure Fund (the "Fund," or the "Infrastructure Fund") seeks total return through growth of capital and current income.

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. 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 the Brookfield Investment Funds. You may also qualify for sales charge discounts or waivers through certain financial intermediaries. More information about these and other discounts is available from your financial professional and in the section entitled "Shareholder Account Information - Initial Sales Charges (Class A Shares Only)" on page 70 of the Fund's Prospectus and in Appendix A, "Sales Charge Reductions and Waivers Available Through Certain Intermediaries," attached to the Fund's Prospectus.

​(1) No sales charge is payable at the time of purchase on investments of $1 million or more, although for such investments the Fund will impose a Contingent Deferred Sales Charge of 1.00% on redemptions made within eighteen months of purchase.

​(2) A Contingent Deferred Sales Charge of 1.00% will be applied to redemptions of Class C Shares made within twelve months of the purchase date.

(3) Brookfield Public Securities Group LLC, the Fund's investment adviser (the "Adviser"), has contractually agreed to waive all or a portion of its investment advisory or administration fees and/or to reimburse certain expenses of the Fund to the extent necessary to maintain the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement (excluding any front-end or contingent deferred sales loads, brokerage commissions and other transactional expenses, acquired fund fees and expenses, interest, taxes, and extraordinary expenses, such as litigation; and other expenses not incurred in the ordinary course of the Fund's business) at no more than 1.25% for Class A Shares, 2.00% for Class C Shares, and 1.00% for Class I Shares. The fee waiver and expense reimbursement arrangement will continue until at least April 30, 2027, and may not be terminated by the

Fund or the Adviser before such time. Thereafter, this arrangement may only be terminated or amended to increase the expense cap as of April 30th of each calendar year (April 29th in a leap year), provided that in the case of a termination by the Adviser, the Adviser will provide the Board of Trustees (the "Board") with written notice of its intention to terminate the arrangement prior to the expiration of its then current term. Any waivers and/or reimbursements made by the Adviser are subject to recoupment from the Fund for a period not to exceed three years after the occurrence of the waiver and/or reimbursement provided that the Fund may only make repayments to the Adviser if such repayment does not cause the Fund's expense ratio (after the repayment is taken into account) to exceed both: (1) the expense cap in place at the time such amounts were waived; and (2) the Fund's current expense cap.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year, and that the Fund's operating expenses remain the same (taking into account the expense limitation for the first year). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

You would pay the following expenses if you did not redeem your shares:

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate 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. During the most recent fiscal year ended December 31, 2025, the Fund's portfolio turnover rate was 83% of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by investing primarily in securities of publicly traded infrastructure companies. Under normal market conditions, the Fund will attempt to achieve its investment objective by investing, as a principal strategy, at least 80% of its net assets (plus the amount of any borrowing for investment purposes) in publicly traded equity securities of infrastructure companies listed on a domestic or

foreign exchange, throughout the world, including the United States (the "80% Policy"), and, as part of the 80% Policy, at least 40% of the Fund's net assets (plus the amount of any borrowing for investment purposes) will be invested in publicly traded securities of infrastructure companies whose primary operations or principal trading market is in a foreign market, and that are not subject to the requirements of the U.S. securities laws, markets and accounting requirements ("Foreign Securities"). The Fund considers an issuer's "primary operations" to be in a foreign market if the issuer (i) is organized under the laws of that country, or (ii) derives at least 50% of its revenues or profits from goods produced or sold, investments made, services performed, or has at least 50% of its assets located within that country. Under normal market conditions, the Fund will maintain exposure to securities of infrastructure companies in the United States and in at least three countries outside the United States. The Fund may also invest up to 25% of its net assets (plus the amount of any borrowing for investment purposes) in energy-infrastructure companies organized as master limited partnerships ("MLPs"). The Fund may invest up to 20% of its net assets (plus the amount of any borrowing for investment purposes) in fixed income securities, including below-investment grade rated securities ("junk bonds"), as described in this Prospectus.

The Fund may change the 80% Policy without shareholder approval. The Fund will provide shareholders with written notice at least 60 days prior to the implementation of any such changes.

The Fund defines an infrastructure company as any company that derives at least 50% of its revenue or profits from the ownership or operation of infrastructure assets. The Fund defines infrastructure assets as the physical structures, networks and systems of transportation, energy, water and sewage, and communication.

Infrastructure assets currently include:

• toll roads, bridges and tunnels;

• airports;

• seaports;

• electricity generation and transmission and distribution lines;

• gathering, treating, processing, fractionation, transportation and storage of hydrocarbon products;

• water and sewage treatment and distribution pipelines;

• communication towers and satellites; and

• railroads.

The Fund may use futures and options on securities, indices and currencies, forward foreign currency exchange contracts, swaps and other derivatives. A derivative is a security or instrument whose value is determined by reference to the value or the change in value of one or more securities, currencies, indices or other financial instruments. The Fund may use derivatives for a variety of purposes, including:

• as a hedge against adverse changes in the market prices of securities, interest rate or currency exchange rates;

• as a substitute for purchasing or selling securities;

• to increase the Fund's return as a non-hedging strategy that may be considered speculative; and

• to manage the Fund's portfolio characteristics.

The Fund may invest up to 20% of its net assets (plus the amount of any borrowing for investment purposes) in fixed income securities, including obligations of the U.S. Government, floating rate loans and money-market instruments. As part of the 20% of the Fund's net assets (plus the amount of any borrowing for investment purposes) that may be invested in fixed income securities, up to 10% of the Fund's net assets (plus the amount of any borrowing for investment purposes) may be invested in below investment grade ("junk") fixed income securities, of which 5% may be invested in fixed income securities rated "CCC" or lower by S&P Global Ratings ("S&P") or "Caa" or lower by Moody's Ratings ("Moody's") or non-rated securities of comparable quality. The Fund, however, may not invest in securities in default.

The Fund may invest up to 25% of its net assets (plus the amount of any borrowing for investment purposes) in publicly traded securities of infrastructure companies, whose primary operations or principal trading market is in an "emerging market." In addition, the Fund may invest up to 15% of its net assets in securities deemed illiquid and may make short sales of securities in an amount not to exceed 10% of the Fund's net assets (plus the amount of any borrowing for investment purposes). Securities in which the Fund may invest include, but are not limited to, common, convertible and preferred stock, stapled securities (as defined herein), income trusts, limited partnerships, and limited partnership interests in the general partners of MLPs, issued by infrastructure companies. Other Fund investments may include warrants, depositary receipts, exchange-traded notes, and investment companies, including exchange-traded funds. The Fund retains the ability to invest in infrastructure companies of any market size capitalization.

The Adviser utilizes a fundamental, bottom-up, value-based selection methodology, taking into account short-term considerations, such as temporary market mispricing, and long-term considerations, such as values of assets and cash flows. The Adviser also draws upon the expertise and knowledge within Brookfield Asset Management ULC and its affiliates, which provide extensive owner/operator insights into industry drivers and trends. The Adviser takes a balanced approach to investing, seeking to mitigate risk through diversification, credit analysis, economic analysis and review of sector and industry trends. The Adviser uses proprietary research to select individual securities that it believes can add value from income and/or the potential for capital appreciation. The proprietary research may include an assessment of a company's general financial condition, its competitive positioning and management strength, as well as industry characteristics and other factors. The Fund may sell a security that becomes overvalued or no longer offers an attractive risk/reward profile. A security may also be sold due to changes in portfolio strategy or cash flow needs.

No assurance can be given that the Fund's investment objective will be achieved. The Fund's policy of concentration in companies in the infrastructure industry is a fundamental policy of the Fund. This fundamental policy may not be changed without the approval of the holders of a majority of the Fund's outstanding voting securities, as defined in the Investment Company Act of 1940, as amended (the "1940 Act").

Principal Risks of Investing in the Fund

Risk is inherent in all investing. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The following summarizes the principal risks that have been identified for the Fund.

Infrastructure Risk. Infrastructure companies may be subject to a variety of factors that may adversely affect their business or operations, including high interest costs in connection with capital construction programs, high leverage, costs associated with environmental and other regulations, the effects of economic slowdown, surplus capacity, increased competition from other providers of services, uncertainties concerning the availability of fuel at reasonable prices, the effects of energy conservation policies and other factors. Some of the specific risks that infrastructure companies may be particularly affected by, or subject to, include the following: regulatory risk, technology risk, regional or geographic risk, natural disasters risk, through-put risk, project risk, strategic asset risk, operation risk, customer risk, interest rate risk, inflation risk and financing risk.

Inflation Risk. Inflation risk is the risk that the value of assets or income from investments will be worth less in the future as inflation decreases the value of money. As inflation increases, the real value of the Fund's shares and distributions thereon can decline. Inflation risk is linked to increases in the prices of goods and services and a decrease in the purchasing power of money. Inflation often is accompanied or followed by a recession, or period of decline in economic activity, which may include job loss and other hardships and may cause the value of securities to go down generally. Inflation risk is greater for fixed-income instruments with longer maturities. In addition, this risk may be significantly elevated compared to normal conditions because of recent monetary policy measures and the current interest rate environment.

Equity Securities Risk. Equity securities represent an ownership interest in an issuer, rank junior in a company's capital structure to debt securities and consequently may entail greater risk of loss than debt securities. Equity securities are subject to the risk that stock prices may rise and fall in periodic cycles and may perform poorly relative to other investments. This risk may be greater in the short term.

Concentration Risk. Because the Fund will invest more than 25% of its net assets (plus the amount of any borrowing for investment purposes) in securities of issuers directly or indirectly engaged in the infrastructure industry, the Fund may be subject to greater volatility with respect to its portfolio securities than a fund that does not concentrate its investments.

Renewable and Sustainable Infrastructure Risk. Renewable and sustainable infrastructure companies may be subject to a variety of factors that may adversely affect their business or operations, including high interest costs in connection with capital construction programs, high leverage, costs associated with environmental and other regulations, the effects of economic slowdown, surplus capacity, increased competition from other providers of services, uncertainties concerning the availability of fuel at reasonable prices, the effects of energy conservation policies and other factors. Some of the specific risks that renewable and sustainable infrastructure companies may be particularly affected by, or subject to, include the following: regulatory risk, technology risk, regional or geographic risk, natural disasters risk, through-put risk, project risk, strategic asset risk, operation risk, customer risk, interest rate risk, inflation risk and financing risk. Renewable and sustainable infrastructure companies may also be subject to higher risk of government regulation.

Investment Risk. An investment in the Fund is subject to investment risk, including the possible loss of the entire principal amount that you invest.

Geopolitical Risk. Occurrence of global events such as war, terrorist attacks, natural disasters, country instability, infectious disease epidemics, pandemics and other public health issues, market instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers and other governmental trade or market control programs, the potential exit of a country from its respective union and related geopolitical events, may result in market volatility and may have long-lasting impacts on both the U.S. and global financial markets. For example, the U.S. government has imposed, and may in the future further increase, tariffs on certain foreign goods, and some foreign governments have instituted retaliatory tariffs on certain U.S. goods. There is significant uncertainty as to further actions that may be taken by the U.S. and foreign governments with respect to trade policy. In addition, ongoing conflicts in Ukraine and the Middle East, and the potential for wider conflict, have increased volatility and uncertainty in the financial markets, adversely affected regional and global economies, and could present material uncertainty and risk with respect to the Fund and the performance of the Fund's investments or operations. These events, as well as other recent geopolitical events, such as rising tensions between the Chinese government and Taiwan, and related changes in foreign and domestic political and economic conditions, could adversely affect individual issuers or related groups of issuers, securities markets, interest rates, secondary trading, credit ratings, inflation, investor sentiment and other factors affecting the value of the Fund's investments.

Adviser Investment Risk. The Adviser and its affiliates (each, an "Adviser Investor") may, from time to time, own a significant amount of the Fund's shares (an "Adviser Investment"). An Adviser Investor may make an Adviser Investment to enable the Fund to reach critical mass or because the Adviser Investor has capital to invest and wants exposure to the Fund's investment strategy or for other reasons. If an Adviser Investment is substantial relative to the Fund's overall asset size, a partial or complete redemption of the Adviser Investment, which may occur at any time, including at the time of other inflows or outflows, may have a material adverse effect on the Fund's expense ratio, portfolio turnover and the overall ability to manage the Fund. The Adviser Investor reserves the right to redeem its Adviser Investment at any time in accordance with applicable law in its sole and absolute discretion.

Portfolio Selection Risk. The Adviser's judgment about the quality, relative yield, relative value or market trends affecting a particular sector or region, market segment, security or about interest rates generally may prove to be incorrect.

Issuer Risk. Issuer risk is the risk that the value of a security may decline for a reason directly related to the issuer, such as management performance, financial leverage and reduced demand for the issuer's goods or service.

Market Risk. Global economies and financial markets are increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund's portfolio may underperform in comparison to securities in general financial markets, a particular financial market, or other asset classes due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. For example, the U.S. and other countries are periodically involved in disputes over trade and other matters, which may result in tariffs, investment restrictions and adverse impacts on affected companies and securities. Trade disputes may adversely affect the economies of the U.S. and its trading partners, as well as companies directly or indirectly affected and financial markets generally. The current political climate, including political and diplomatic events within the U.S. and abroad, may adversely affect the U.S. regulatory landscape, the general market environment and/or investor sentiment, which could have an adverse impact on the Fund's investments and operations. In addition, the value of the Fund's investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. For example, the ongoing armed conflicts between Russia and Ukraine in Europe and

among Israel, Iran, Hamas and other militant groups in the Middle East have caused and may continue to cause significant market disruptions.

Interest Rate Risk. A rise in interest rates will cause the price of fixed income securities to fall. Generally, fixed income securities with longer maturities carry greater interest rate risk. Interest rate changes may be influenced by a number of factors, including government and central banking authority actions, inflation expectations, and supply and demand. Generally, when interest rates rise, the value of fixed income securities can be expected to decline. The longer the maturity of a fixed income security, the greater its sensitivity to interest rate changes. The Fund may be subject to heightened interest rate risk as a result of changes in economic conditions, inflation and government monetary policy, such as changes in the federal funds rate. There is no way of predicting the frequency or quantum of potential interest rate changes.

Liquidity Risk. Some securities, including options and swaps, held by the Fund may be difficult to sell, not publicly traded, or illiquid, particularly during times of market turmoil or adverse investor perceptions. Such securities may include securities that are not readily marketable and may be difficult to value. If the Fund desires to sell such securities when a ready buyer is not available at a price that the Fund deems representative of their value, the value of the Fund could be adversely affected. If the Fund is forced to sell an illiquid asset to meet redemption requests or other cash needs, the Fund may be forced to sell at a loss.

Construction and Development Risk. Investments in new or development stage infrastructure projects, carry the risk that a project may not be completed within budget, within the agreed time frame and to the agreed specification.

Foreign (Non-U.S.) Securities Risk. Risks of investing in foreign securities include currency risks, future political and economic developments and possible imposition of foreign withholding taxes on income payable on the securities. In addition, there may be less publicly available information about a foreign issuer than about a domestic issuer, and foreign issuers may not be subject to the same accounting, auditing and financial recordkeeping standards and requirements as domestic issuers. These risks are more pronounced in the securities of companies located in emerging markets.

Emerging Markets Risk. Securities of companies in emerging markets or companies with significant exposure to emerging markets may be more volatile than those of companies in more developed markets. Emerging market countries generally have less developed markets and economies and, in some countries, less mature governments and governmental institutions. Investing in securities of companies in emerging markets may entail special risks relating to potential economic, political or social instability and the risks of expropriation, nationalization, confiscation or the imposition of restrictions on foreign investment, the lack of hedging instruments, and on repatriation of capital invested. In

addition, the availability and reliability of information material to an investment decision, particularly financial information from these companies in emerging markets, may be limited in comparison to the scope and reliability of financial information provided by U.S. companies.

Foreign Currency Risk. The Fund will invest in instruments denominated in U.S. and foreign currencies. The Fund's net asset value ("NAV") could decline as a result of changes in the exchange rates between foreign currencies in which a security is denominated and the U.S. dollar. Certain foreign countries may impose restrictions on the ability of issuers of foreign securities to make payment of principal and interest to investors located outside the country, due to blockage of foreign currency exchanges or otherwise.

Commodity-Related Investments Risk. The value of commodities investments will generally be affected by overall market movements and factors specific to a particular industry or commodity, which may include weather, embargoes, tariffs, and economic health, political, international regulatory and other developments. Exposure to the commodities markets may subject the Fund to greater volatility than investments in traditional securities.

Fixed Income Risk. The value of fixed income securities fluctuate based on a variety of factors including interest rates, the maturity of the security, the creditworthiness of an issuer, the liquidity of the security and general bond market conditions. At times there may be an imbalance of supply and demand in the fixed income markets which could result in greater price volatility, less liquidity, wider trading spreads and a lack of price transparency.

The value of fixed income securities may also be dependent on the creditworthiness of the issuer of such securities. A deterioration in the financial condition of an issuer or a deterioration in general economic conditions could cause an issuer to fail to pay principal or interest when due.

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.

"Junk" Bond Risk. Debt securities that are below investment grade, called "junk bonds," generally offer a higher yield than is offered by higher rated securities, but are speculative, have a higher risk of default or are already in default, tend to be less liquid and are more difficult to value than higher grade securities. Junk bonds tend to be volatile and more susceptible to adverse events and negative sentiments.

Leverage Risk. Some transactions entered into by the Fund may give rise to a form of economic leverage. These transactions may include, among others, derivatives, and may expose the Fund to greater risk and increase its costs. The use of leverage may cause the Fund to liquidate portfolio positions when it may not be advantageous to do so to satisfy its obligations or to meet

any required asset segregation requirements. Increases and decreases in the value of the Fund's portfolio will be magnified when the Fund uses leverage.

MLP Risk. An MLP that invests in a particular industry (e.g., oil and gas) will be harmed by detrimental economic events within that industry. As partnerships, MLPs may be subject to less regulation (and less protection for investors) under state laws than corporations. MLPs benefit from various tax provisions that may not be available in the future. In addition, MLPs may be subject to state taxation in certain jurisdictions, which may reduce the amount of income an MLP pays to its investors.

Return of Capital Risk. The Fund expects to make quarterly distributions at a level percentage rate regardless of its quarterly performance. All or a portion of such distributions may represent a return of capital. A return of capital is the portion of the distribution representing the return of your investment in the Fund. A return of capital is generally tax-free to the extent of a shareholder's basis in the Fund's shares and reduces the shareholder's basis in their shares and results in a higher capital gain or lower capital loss when the shares on which the return of capital distribution was received are sold. After a shareholder's basis in the shares has been reduced to zero, return of capital distributions will be treated as gain from the sale of the shareholder's shares.

Redemption Risk. The Fund may need to sell its holdings in order to meet shareholder redemption requests. The Fund could experience a loss when selling securities to meet redemption requests if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Preferred Securities Risk. There are various risks associated with investing in preferred securities, including credit risk, interest rate risk, deferral and omission of distributions, subordination to bonds and other debt securities in a company's capital structure, limited liquidity, limited voting rights and special redemption rights.

Derivatives Risk. The Fund's use of derivatives may reduce the Fund's returns and/or increase volatility. Volatility is defined as the characteristic of a security, an index or a market to fluctuate significantly in price within a short time period. Derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligation. The possible lack of a liquid secondary market for derivatives and the resulting inability of the Fund to sell or otherwise close a derivatives position could expose the Fund to losses and could make derivatives more difficult for the Fund to value accurately. Valuation may be more difficult in times of market turmoil since many investors and market makers may be reluctant to purchase complex instruments or quote prices for them. Certain transactions in derivatives involve substantial leverage risk and may expose the Fund to potential losses that exceed the amount originally invested by the Fund.

Small- and Mid-Capitalization Risk. The risk that returns from small- and mid-capitalization stocks may trail returns from the overall stock market. Historically, these stocks have been more volatile in price than the large-capitalization stocks.

Short Sales Risk. Because making short sales in securities that it does not own exposes the Fund to the risks associated with those securities, such short sales involve speculative exposure risk. The Fund will incur a loss as a result of a short sale if the price of the security increases between the date of the short sale and the date on which the Fund replaces the security sold short.

Regulatory Risk. Infrastructure companies may be subject to regulation by various governmental authorities and may also be affected by governmental regulation of rates charged to services, the imposition of special tariffs and changes in tax laws, environmental laws and regulations, regulatory policies, accounting standards and general changes in market sentiment towards infrastructure assets. Infrastructure companies' inability to predict, influence or respond appropriately to changes in law or regulatory schemes could adversely impact their results of operations.

The Fund's shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency.

Performance

The accompanying bar chart and table provide some indication of the risks of investing in the Fund by showing how the Fund's total return has varied for annual periods through December 31, 2025, and by showing how the Fund's average annual total returns for one-, five-, and ten-year periods and since inception compare with those of a broad measure of market performance and additional indices that have investment characteristics similar to those of the Fund. On March 25, 2021, the Board, on behalf of the Fund, approved a proposal to close the Fund's Class I Shares (the "Legacy Class I Shares"). Following the close of business on April 30, 2021, shareholders holding the Legacy Class I Shares had their shares automatically converted (the "Conversion") into the Fund's Class Y Shares (the "Legacy Class Y Shares"). Following the Conversion, the Fund's Legacy Class Y Shares were renamed "Class I Shares" (the "new Class I Shares"). As a result of the Conversion, the Fund's new Class I Shares adopted the Legacy Class Y Shares' performance and accounting history. Figures shown in the bar chart reflect the performance history of the Fund's new Class I Shares (i.e., the Legacy Class Y Shares). The Fund's Legacy Class I Shares and Legacy Class Y Shares had substantially similar returns because (i) the shares were invested in the same portfolio of securities; and (ii) the shares had the same expense structure.

For periods prior to April 30, 2021, the performance information for the Fund's new Class I Shares reflects the performance history of the Legacy Class Y Shares. The Fund's performance (before and after taxes) is

not an indication of how the Fund will perform in the future. Updated performance information is available at https://privatewealth.brookfield.com/fund/brookfield-global-listed-infrastructure-fund or by calling 1-855-244-4859.
