---

<sup>(1)</sup> 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.

<sup>(2)</sup> 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.

<sup>(3)</sup> "Other Expenses" for Class A and Class C Shares are based on estimated amounts for the current fiscal year.

<sup>(4)</sup> 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, such as deferred income tax expenses, 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 for at least one year from the effective date of the Fund's registration statement, 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, 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. Although your actual costs may be higher or lower, based on these assumptions your costs would be:**

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | 1 Year | 3 Years | 5 Years | 10 Years |
|  Class A Shares | $596 | $931 | $1289 | $2295 |
|  Class C Shares | $303 | $708 | $1240 | $2697 |
|  Class I Shares | $102 | $402 | $723 | $1635 |

---

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

|:---|:---|:---|:---|:---|
|  | 1 Year | 3 Years | 5 Years | 10 Years |
|  Class C Shares | $203 | $708 | $1240 | $2697 |

---

#### 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 may indicate higher transaction costs and may result in higher realized taxes at the fund level. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the fiscal year ended December 31, 2024, the portfolio turnover rate of the Fund was 69% of the average value of its portfolio.

#### Principal Investment Strategies
The Fund seeks to achieve its investment objective by investing at least 80% of its net assets, plus borrowings 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"). Under normal market conditions, at least 40% of the Fund's net assets, plus borrowings for investment purposes, may 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, and the Fund may maintain exposure to securities of infrastructure companies in the United States and in at least three countries outside the United States. 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. The Fund may also invest, as a principal strategy, up to 25% of its net assets in infrastructure companies organized as master limited partnerships ("MLPs").

For purposes of the 80% Policy, an infrastructure company is any company that makes or derives at least 50% of its recurring revenues, cash flows, or Regulated Asset Base (defined below) from, and has committed at least 50% of its future capital expenditures to, infrastructure business activities, including any, or a combination of, the following business activities:

• Power production, including renewables (*e.g.*, wind, solar, hydroelectric), low-to-zero carbon energy production (*e.g.*, nuclear, biomass, and other forms of clean energy), and reliable baseload (*e.g.*, gas);

• Electric & gas transmission and distribution networks;

• "Circular economy" products and systems (*i.e.*, products and systems designed to minimize waste and enable greater recycling and reuse of materials), including, water utilities systems, waste systems, and other energy recapture and recycling systems (*e.g.*, methane capture for renewable natural gas);

• Sustainable solutions design and implementation, such as grid modernization, smart grid technology, energy efficiency, electricity storage (*e.g.*, batteries, fuel cells, etc.), and/or equipment manufacturing for power production (both large-scale and behind-the-meter); and/or

• Data infrastructure (*e.g.*, communication towers, data centers).

------

"Regulated Asset Base" means the value of the asset base from which an infrastructure company, such as a utility company, is permitted to earn an allowed rate of return on its investment, as set by relevant regulatory authorities. The Regulated Asset Base may include the value of water, gas and electricity transmission and distribution lines, certain generation assets, gas mains, water treatment facilities and meters, as well as other assets. Where applicable, the Regulated Asset Base model sets a value on a company's invested capital, which in turn determines the total revenues that such company is permitted to earn.

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 may invest up to 25% of its net assets, plus borrowings for investment purposes, in publicly traded securities of infrastructure companies, whose primary operations or principal trading market is in an "emerging market." In selecting the Fund's emerging market securities, the Adviser primarily looks to the emerging market countries that are included in the MSCI Emerging Markets Index (USD), which currently include Brazil, Chile, China, Colombia, Czech Republic, Egypt, Greece, Hungary, India, Indonesia, Korea, Kuwait, Malaysia, Mexico, Peru, Philippines, Poland, Qatar, Saudi Arabia, South Africa, Taiwan, Thailand, Turkey and the United Arab Emirates. The Fund may invest in securities of foreign companies in the form of American Depositary Receipts ("ADRs"), Global Depositary Receipts ("GDRs") and European Depositary Receipts ("EDRs"). In addition, the Fund may invest up to 15% of its net assets in securities deemed illiquid. 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. The allocation of capital across asset classes and strategies will vary upon market opportunity and other factors.

Under normal market conditions, the Fund will invest more than 25% of its total assets in the renewable and sustainable infrastructure industry. The policy of concentration is a fundamental policy. 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 Company 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. While many of the risks below could be present with respect to other investments, these risks may be particularly important to investments in infrastructure companies.

*Environmental Risk.* Infrastructure assets may be subject to numerous laws, rules and regulations relating to environmental protection. Under various environmental statutes, rules and regulations, a current or previous owner or operator of real property may be liable for non-compliance with applicable environmental and health and safety requirements and for the costs of investigation, monitoring, removal or remediation of hazardous materials. These laws often impose liability, whether or not the owner or operator knew of or was responsible for the presence of hazardous materials. The presence of these hazardous materials on a property could also result in personal injury or property damage or similar claims by private parties. Persons who arrange for the disposal or treatment of hazardous materials may also be liable for the costs of removal or remediation of these materials at the disposal or treatment facility, whether or not that facility is or ever was owned or operated by that person. The Fund may be exposed to substantial risk of loss from environmental claims arising in respect of its investments, and such loss may exceed the value of such investments. Furthermore, changes in environmental laws or in the environmental condition of a portfolio investment may create liabilities that did not exist at the time of acquisition of an investment and that could not have been foreseen. For example, new environmental regulations may create costly compliance procedures for infrastructure assets.

*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, Russia's military invasion of Ukraine and the conflict between Israel and Hamas, 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 the United Kingdom's departure from the European Union (commonly referred to as "Brexit"), 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.

*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.

*Concentration Risk.* Because the Fund will invest more than 25% of its total assets in the securities of issuers directly or indirectly engaged in the renewable and sustainable 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.

*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.

*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.

*Emerging Markets Risk.* Securities of companies in 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 (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.

*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.

------

*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.

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

*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.

*Management Risk.* The Fund has an actively managed portfolio. The Adviser applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these will produce the desired results.

*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.

*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.

*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, Hamas and other militant groups in the Middle East have caused and may continue to cause significant market disruptions. As a result, there is significant uncertainty around how these conflicts will evolve, which may result in market volatility and may have long-lasting impacts on both the U.S. and global financial markets.

*Liquidity Risk.* Derivative instruments, including options and swaps, especially when traded in large amounts, may not be liquid in all circumstances, so that in volatile markets the Fund may not be able to close out a position without incurring a loss. In addition, daily limits on price fluctuations and speculative position limits on exchanges on which the Fund may conduct its transactions in derivative instruments may prevent profitable liquidation of positions, subjecting the Fund to the potential of greater losses.

*Infectious Illness Risk.* A widespread outbreak of an infectious illness may result in travel restrictions, disruption of healthcare services, prolonged quarantines, cancellations, supply chain disruptions, business closures, lower consumer demand, layoffs, ratings downgrades, defaults and other significant economic, social and political impacts. Such events may adversely affect the Fund, its investments, and the value of your investment in the Fund.

*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 the performance history of the Fund and Brookfield Global Renewables & Sustainable Infrastructure LP (the "Predecessor Fund"). As of the close of business on February 4, 2022, the Fund acquired all of the assets, subject to liabilities, of the Predecessor Fund through a tax-free reorganization (the "Reorganization"). In connection with the Reorganization, shares of the Predecessor Fund were exchanged for Class I Shares of the Fund. As a result of the Reorganization, the Fund's Class I Shares adopted the Predecessor Fund's performance history. The Predecessor Fund was an unregistered limited partnership, did not qualify as a regulated investment company for federal income purposes and did not have a distribution policy (*i.e.*, the Predecessor Fund did not pay dividends and distributions). As a result of the different tax treatment, after-tax returns for the Predecessor Fund are not shown. Figures shown in the bar chart reflect

------

the performance history of the Fund's Class I Shares and do not reflect sales charges. For periods prior to February 4, 2022, the performance information for the Fund's Class I Shares reflects the performance history of the Predecessor Fund. If sales charges were reflected, returns would be less than these shown. The performance table shows how the Fund's average annual total returns compare with those of a broad measure of market performance and additional indices that have

investment characteristics similar to those of the Fund. The Fund's Class A and Class C Shares would have substantially similar returns because the shares are invested in the same portfolio of securities, and the returns would differ only to the extent that the classes do not have the same expenses. Updated performance information is available on the Fund's website at https://www.brookfieldoaktree.com/fund/brookfield-next-generation-infrastructure-fund or by calling 1-855-244-4859.

<sup>(1)</sup> Figures do not reflect sales charges. If they did, returns would be lower. For periods prior to February 4, 2022, the bar chart reflects the performance history of the Predecessor Fund. The Class A Shares and Class C Shares would have substantially similar returns because the shares are invested in the same portfolio of securities, and the returns would differ only to the extent that the classes do not have the same expenses, such as sales loads that are not reflected in the bar chart. If sales loads were reflected, the Fund's returns would have been less than those shown.

During the period of time shown in the bar chart, the highest return for a calendar quarter was 38.61% (quarter ended December 31, 2020) and the lowest return for a calendar quarter was –15.18% (quarter ended September 30, 2023).
