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 Expense Example, affect the Fund's performance.

The First Sentier Global Listed Infrastructure Fund, a series of Advisors Series Trust, was the predecessor to the Fund (the "Global Listed Predecessor Fund"). During its fiscal year ended October 31, 2025, the Global Listed Predecessor Fund's portfolio turnover rate was 70.19% of the average value of its portfolio.

First Sentier Global Listed Infrastructure Fund

Principal Investment Strategies

The Global Listed Fund seeks to achieve its investment objective by investing primarily in securities of publicly traded infrastructure companies. The Fund defines infrastructure companies as those companies that derive at least 65% of their operating earnings from the ownership or operation of infrastructure assets. The Fund defines infrastructure assets as the physical structures, networks and systems of transportation, energy, water, waste, and communication. The Fund typically invests in companies that can adjust the fees they charge customers and counterparties in line with inflation, in accordance with contractual terms or regulation, or through renegotiation due to the essential nature and pricing power of infrastructure assets. Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in publicly traded equity securities of infrastructure companies listed on an exchange, throughout the world including emerging markets and the United States. Emerging markets are defined as those countries that are either i) not classified by MSCI or FTSE as developed markets, ii) categorized by the World Bank as middle or low-income, or iii) not members of the Organisation for Economic Cooperation and Development. As part of the 80%, the Fund will invest at least 30% of its net assets and, under normal circumstances, at least 40% of its net assets, 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, i.e., 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 circumstances, 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 Global Listed Fund seeks to invest in the securities of companies which have high barriers to entry, strong pricing power, sustainable growth and predictable cash flows. The majority of infrastructure securities in which the Fund typically invests are within the following Global Industry Classification Standard ("GICS") sectors:

1)

oil and gas storage and transportation;

2)

airport services;

3)

highways and rail tracks;

4)

marine ports and services; and

5)

multi/electric/gas/water utilities.

Equity securities in which the Global Listed Fund may invest include, but are not limited to, common and preferred stock of companies of any size market capitalizations. The Fund may invest up to 75% of its net assets in depositary receipts, such as American Depositary Receipts ("ADRs"), European Depositary Receipts ("EDRs") and Global Depositary Receipts ("GDRs"). The Fund may also invest in stapled securities to gain exposure to infrastructure companies in Australia. A stapled security is a security that is comprised of two parts that cannot be separated from one another, a unit of a trust and a share of a company. The Fund may also invest in initial public offerings ("IPOs").

As part of the 80% of the Global Listed Fund's investments in publicly traded equity securities of infrastructure companies, the Fund may invest up to 30% of its net assets in real estate investment trusts ("REITs") listed on a domestic or foreign exchange and up to 20% of its net assets in limited partnerships and master limited partnerships ("MLPs") listed on a domestic or foreign exchange. All REITs and MLPs that the Fund may invest in must meet the Fund's definition of an infrastructure company.

As a fundamental policy, the Global Listed Fund will invest more than 25% of its net assets in the securities issued by companies operating in the infrastructure industry. The Global Listed Fund's investment strategy is based on active, bottom-up stock selection which seeks to identify mispricing. The strategy seeks to minimize risk through on-the-ground research, a focus on quality, and sensible portfolio construction.

Securities within the Fund's wider investment universe are screened for infrastructure characteristics, analyzed and then ranked by value and quality. The portfolio is then constructed by the portfolio managers, based primarily on these rankings. Sector and region risks are also monitored as a risk management overlay which aims to ensure appropriate portfolio diversification along sector and regional lines.

The portfolio managers may choose to sell securities when they observe a security moving to a lower position within the portfolio managers' value and quality ranking system. This can occur through, among other things:

A rise in a company's share price, leading to decreased upside potential and a lower value ranking

A downgrade in a company's discounted cash flow valuation, leading to lower value ranking

A downgrade of a company's quality score, leading to a lower quality ranking.

Peer review of the security selection process ensures the team is not locked into high conviction buys or sells but rather identifies market inefficiency and sells/buys the security before the opportunity has closed.

Principal Risks

By itself, the Fund is not a complete, balanced investment plan. The Fund cannot guarantee that it will achieve its investment objectives. Losing all or a portion of your investment is a risk of investing in the Fund. The following risks are considered principal and could affect the value of your investment in the Fund:

Management Risk. The Global Listed Fund is subject to management risk as an actively managed portfolio. First Sentier Investors (Australia) IM Ltd (the "Sub-Adviser") will apply 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. The Sub-Adviser may be incorrect in its assessment of a stock's appreciation potential.

General Market Risk. Economies and financial markets throughout the world are becoming 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; market instability; financial system 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. In addition, the value of the Fund's investments may be negatively affected by the occurrence of

Summary Prospectus February 28, 2026

First Sentier Global Listed Infrastructure Fund

global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. Conflict, loss of life and disaster connected to ongoing armed conflict between Ukraine and Russia in Europe and Israel and Hamas in the Middle East could have severe adverse effects on the region, including significant adverse effects on the regional or global economies and the markets for certain securities. The U.S. and the European Union imposed sanctions on certain Russian individuals and companies, including certain financial institutions, and have limited certain exports and imports to and from Russia. The war has contributed to recent market volatility and may continue to do so.

Equity Securities Risk. Equity securities may fluctuate in value, sometimes rapidly and unpredictably, more than other asset classes, such as fixed income securities, and may fluctuate in price based on actual or perceived changes in a company's financial condition and overall market and economic conditions and perceptions. If the market prices of the Fund's investments fall, the value of your investment in the Fund will go down.

Infrastructure Companies 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.

In particular, the operations of infrastructure projects are exposed to unplanned interruptions caused by significant catastrophic events, such as cyclones, earthquakes, landslides, floods, explosion, fire, terrorist attack, major plant breakdown, pipeline or electricity line rupture or other disasters. Operational disruption, as well as supply disruption, could adversely impact the cash flows available from these assets.

Further, national and local environmental laws and regulations affect the operations of infrastructure projects. Standards are set by these laws, and regulations are imposed regarding certain aspects of health and environmental quality, and they provide for penalties and other liabilities for the violation of such standards, and establish, in certain circumstances, obligations to remediate and rehabilitate current and former facilities and locations where operations are, or were, conducted. These laws and regulations may have a detrimental impact on the financial performance of infrastructure projects.

Utilities Sector Risk. The utilities sector is subject to significant government regulation and oversight. Deregulation, however, may subject utility companies to greater competition and may reduce their profitability. Companies in the utilities sector may be adversely affected due to increases in fuel and operating costs, rising costs of financing capital construction and the cost of complying with U.S. federal and state regulations, among other factors.

Industrials Sector Risk. Companies in the industrials sector may be adversely affected by, among other things, supply and demand for raw materials and for products and services. In addition, government regulation, world events, exchange rates and economic conditions, technological developments and product obsolescence, fuel prices, labor agreements, insurance costs, and liabilities for environmental damage and general civil liabilities will likewise affect the performance of these companies.

Concentration Risk. Since the securities of companies in the same industry or group of industries will comprise a significant portion of the Fund's portfolio, the Fund will be more significantly impacted by adverse developments in such industries than a fund that invests in a wider variety of industries.

Foreign Securities Risk. Investing in securities of foreign issuers or issuers with significant exposure to foreign markets involves additional risks. Foreign markets can be less liquid, less regulated, less transparent and more volatile than U.S. markets. The value of the Fund's foreign investments may decline, sometimes rapidly or unpredictably, because of factors affecting the particular issuer as well as foreign markets and issuers generally, such as unfavorable or unsuccessful government actions, reduction of government or central bank support, wars, tariffs and trade disruptions, political or financial instability, social unrest or other adverse economic or political developments. Changes in currency rates and exchange control regulations, and the imposition of sanctions, confiscations, trade restrictions, and other government restrictions by the United States and/or other governments may adversely affect the value of the Fund's investments in foreign securities. In addition, issuers of foreign securities often are not subject to as much regulation as U.S. issuers, and the reporting, accounting, custody, and auditing standards to which those issuers are subject often are not as rigorous as U.S. standards. These risks can be elevated in emerging markets. Investments in emerging markets are generally more volatile than investments in developed foreign markets.

Emerging Markets Risk. The Fund's investments in non-U.S. issuers in developing or emerging market countries may involve increased exposure to changes in economic, social and political factors as compared to investments in more developed countries. The economies of most emerging market countries are in the early stage of capital market development and may be dependent on relatively fewer industries. As a result, their economic systems are still evolving. Their legal and political systems may also be less stable than those in developed economies. Securities markets in these countries can also be smaller, and there may be increased settlement risks. The Public Company Accounting Oversight Board, which regulates auditors of U.S. companies, is unable to inspect audit work papers in certain foreign countries. Investors in emerging markets often have limited rights and few practical remedies to pursue shareholder claims, including class actions or fraud claims, and the ability of the SEC, the U.S. Department of Justice and other authorities to bring and enforce actions against foreign issuers or foreign persons is limited. Emerging market countries often suffer from currency devaluation and higher rates of inflation. Due to these risks, securities issued in developing or emerging countries may be more volatile, less liquid, and harder to value than securities issued in more developed countries.

Foreign Currency Risk. Because the Fund invests in securities denominated in foreign currencies, the U.S. dollar values of its investments fluctuate as a result of changes in foreign exchange rates. Such changes will also affect the Fund's income.

Depositary Receipt Risk. Depositary receipts may be purchased through "sponsored" or "unsponsored" facilities. A sponsored facility is established jointly by the issuer of the underlying security and a depositary, whereas a depositary may establish an unsponsored facility without participation by the issuer of the depositary security. Holders of unsponsored depositary receipts generally bear all the costs of such facilities and the depositary of an unsponsored facility frequently is under no obligation to distribute shareholder communications received

from the issuer of the deposited security or to pass through voting rights to the holders of such receipts of the deposited securities. In addition, investment in ADRs, EDRs and GDRs may be less liquid than the underlying shares in their primary trading market.

Stapled Securities Risk. As discussed above, a stapled security is comprised of two different securities -a unit of a trust and a share of a company-that are "stapled" together and treated as a unit at all times, including for transfer or trading. The characteristics and value of a stapled security are influenced by both underlying securities. The listing of stapled securities on a domestic or foreign exchange does not guarantee a liquid market for stapled securities.

Real Estate Investment Trusts Risk. The value of real estate investment trusts and similar REIT-like entities ("REITs") may be affected by the condition of the economy as a whole and changes in the value of the underlying real estate, the creditworthiness of the issuer of the investments, property taxes, interest rates, liquidity of the credit markets and the real estate regulatory environment. REITs that concentrate their holdings in specific businesses, such as apartments, offices or retail space, will be affected by conditions affecting those businesses.

Limited Partnership and MLP Risk. Investments in securities (units) of partnerships, including MLPs, involve risks that differ from an investment in common stock. Holders of the units of limited partnerships have more limited control and limited rights to vote on matters affecting the partnership. Certain tax risks are associated with an investment in units of limited partnerships. In addition, conflicts of interest may exist between common unit holders, subordinated unit holders and the general partner of a limited partnership, including a conflict arising as a result of incentive distribution payments. In addition, investments in certain investment vehicles, such as limited partnerships and MLPs, may be illiquid. Such partnership investments may also not provide daily pricing information to their investors, which will require the Fund to employ fair value procedures to value its holdings in such investments.

Initial Public Offering Risk. The market value of IPO shares may fluctuate considerably due to factors such as the absence of a prior public market, unseasoned trading, the small number of shares available for trading and limited information about the issuer. The purchase of IPO shares may involve high transaction costs. IPO shares are subject to market risk and liquidity risk.

Small- and Medium-Sized Companies Risk. Small- and medium-sized companies often have less predictable earnings, more limited product lines, markets, distribution channels or financial resources and the management of such companies may be dependent upon one or few key people. The market movements of equity securities of small- and medium-sized companies may be more abrupt and volatile than the market movements of equity securities of larger, more established companies or the stock market in general and small-sized companies in particular, are generally less liquid than the equity securities of larger companies.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
