GQG Partners Global Quality Equity Fund

Investment Objective

The GQG Partners Global Quality Equity Fund (the “Global Quality Equity Fund” or the “Fund”) seeks long-term capital appreciation.

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy, hold and sell Investor Shares, Institutional Shares and R6 Shares of the Fund. You may be required to pay commissions and/or other forms of compensation to a broker for transactions in Institutional Shares, which are not reflected in the table or the example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

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

1

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:

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 total annual Fund operating expenses or in the example, affect the Fund’s performance. During its most recent fiscal year, the Fund’s portfolio turnover rate was 184% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities. This investment policy may be changed by the Fund upon 60 days’ prior written notice to shareholders.

The equity securities in which the Fund invests are primarily publicly traded common stocks but may also include warrants and preferred stocks. For purposes of the Fund’s 80% investment policy, equity securities also include exchange-traded funds (“ETFs”) with economic characteristics similar to equity securities, depositary receipts (including unsponsored depositary receipts and American Depositary Receipts (“ADRs”), European Depositary Receipts (“EDRs”) and Global Depositary Receipts (“GDRs”)), which are certificates typically issued by a bank or trust company that represent ownership interests in securities of non-U.S. companies, and participation notes (“P-Notes”), which are derivative instruments designed to replicate equity exposure in certain foreign markets where direct investment is either impossible or difficult due to local investment restrictions. The Fund may invest in initial public offerings (“IPOs”) and securities of companies with any market capitalization. The Fund may also invest in U.S. Treasury securities, and

2

in ETFs that attempt to track the price movements of commodities, including gold.

Under normal circumstances, the Fund invests in at least five countries, which may include the United States, and invests at least 40% of its total assets in securities of non-U.S. companies or, if conditions are not favorable, invests at least 30% of its total assets in securities of non-U.S. companies. The Fund considers a company to be a non-U.S. company if: (i) at least 50% of the company’s assets are located outside of the U.S.; (ii) at least 50% of the company’s revenue is generated outside of the U.S.; (iii) the company is organized, conducts its principal operations, or maintains its principal place of business or principal manufacturing facilities outside of the U.S.; (iv) the company’s securities are traded principally outside of the U.S.; or (v) the Adviser otherwise believes that the company’s assets are exposed to the economic fortunes and risks of a non-U.S. country (because, for example, the Adviser believes that the company’s growth is dependent on the country). The Fund may invest in equity securities of companies in both developed and emerging markets and may focus its investments in a particular country or geographic region, including the United States. Emerging market countries generally include every country in the world except the U.S., Canada, Japan, Australia, New Zealand, and most of the countries in Western Europe.

The Fund may also invest in A Shares of companies based in the People’s Republic of China (“China”) that trade on the Shanghai Stock Exchange and the Shenzhen Stock Exchange through the Shanghai - Hong Kong and Shenzhen - Hong Kong Stock Connect programs (“Stock Connect”). Stock Connect is a mutual stock market access program designed to, among other things, enable foreign investments in China.

In managing the Fund’s investments, the Adviser typically pursues a “growth style” of investing as it seeks to capture market inefficiencies which the Adviser believes are driven by investors’ propensity to be short-sighted and overly focused on quarter-to-quarter price movements rather than on a company’s fundamentals over a longer time horizon (5 years or more). The Adviser believes that this market inefficiency tends to lead investors to underappreciate the compounding potential of quality, growing companies. To identify this subset of companies, the Adviser generates investment ideas from a variety of sources, ranging from institutional knowledge and industry contacts, to the Adviser’s proprietary screening process that seeks to identify suitable companies based on several quality factors such as rates of return on equity and total capital, margin stability and profitability. Ideas are then subject to rigorous fundamental analysis as the Adviser seeks to identify and invest in companies that it believes reflect higher quality opportunities on a forward-looking basis. Specifically, the Adviser seeks to buy companies

3

that it believes are reasonably priced and have strong fundamental business characteristics and sustainable and durable earnings growth relative to peers, comparable businesses, or its own history. The Adviser seeks to outperform peers over a full market cycle by seeking to capture market upside while limiting downside risk through the Adviser’s focus on securities it believes are higher quality than the overall market and the Adviser’s willingness to react proactively to perceived changes in risk. For these purposes, a full market cycle can be measured from a point in the market cycle (e.g., a peak or trough) to the corresponding point in the next market cycle.

Many of the stocks in which the Fund invests may be considered to be “growth” stocks, in that they may have, relative to the MSCI All Country World Index (Net), above-average rates of earnings growth over a 3-5 year time horizon, and thus may experience above-average increases in stock prices, subject to the Adviser’s criteria for quality. The Fund may also purchase stocks that would not fall into the traditional “growth” style box.

In constructing the Fund’s portfolio of securities, the Adviser is not constrained by sector or industry weights in the Fund’s benchmark index. The Fund may invest in any economic sector and, at times, emphasize one or more particular industries or sectors in the portfolio construction process. The Adviser relies on individual stock selection driven by a bottom-up research process rather than seeking to add value based on “top-down”, macro based criteria.

The Adviser may sell a company if the Adviser believes that the company’s long-term competitive advantage or relative earnings growth prospects have deteriorated, or the Adviser has otherwise lost conviction that the company reflects a higher quality opportunity than other available investments on a forward looking basis. The Adviser also may sell a company if the company has met its price target or is involved in a business combination, if the Adviser identifies a more attractive investment opportunity, or the Adviser wishes to reduce the Fund’s exposure to the company or a particular country or geographic region.

The Fund is classified as “non-diversified,” which means that it may invest a larger percentage of its assets in a smaller number of issuers than a diversified fund.

Principal Risks

As with all mutual funds, there is no guarantee that the Fund will achieve its investment objective. You could lose money by investing in

4

the Fund. A Fund share is not a bank deposit and it is not insured or guaranteed by the FDIC or any government agency.

Equity Risk – Since it purchases equity securities, the Fund is subject to the risk that stock prices may fall over short or extended periods of time. Historically, the equity market has moved in cycles, and the value of the Fund’s securities may fluctuate from day to day. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These factors contribute to price volatility, which is the principal risk of investing in the Fund.

Market Risk – The risk that the market value of an investment may move up and down, sometimes rapidly and unpredictably. The Fund’s NAV per share will fluctuate with the market prices of its portfolio securities. Market risk may affect a single issuer, an industry, a sector or the market as a whole. Markets for securities in which the Fund invests may decline significantly in response to adverse issuer, political, geopolitical (including war and armed conflict), regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Similarly, extraordinary events outside the control of the Fund, including acts of God (e.g., flood, earthquake, hurricane or other natural disaster), acts of war, the impact of any epidemic or pandemic or widespread fear that such events may occur, could negatively affect the global economy, as well as the economies of individual countries, the financial performance of individual companies and sectors, and the markets in general in significant and unforeseen ways. Any such impact could adversely affect the prices and liquidity of the securities and other instruments in which the Fund invests, which in turn could negatively impact the Fund’s performance and cause losses on your investment in the Fund. Recent examples include pandemic risks related to COVID-19 and aggressive measures taken worldwide in response by governments and businesses, elevated inflation levels, problems in the banking sector and wars in Europe and in the Middle East.

Foreign Company Risk – Investing in foreign companies, including direct investments and investments through depositary receipts and P-Notes, poses additional risks since political and economic events unique to a country or region will affect those markets and their issuers. These risks will not necessarily affect the U.S. economy or similar issuers located in the U.S. Foreign companies are generally not subject to the regulatory controls imposed on U.S. issuers and, as a consequence, there is generally less publicly available information about foreign

5

securities than is available about domestic securities. Income from foreign securities owned by the Fund may be reduced by a withholding tax at the source. Foreign securities may also be more difficult to value than securities of U.S. issuers. In addition, periodic U.S. Government restrictions on investments in issuers from certain foreign countries may require the Fund to sell such investments at inopportune times, which could result in losses to the Fund.

Emerging Markets Securities Risk – The Fund’s investments in emerging markets securities, including A Shares of Chinese companies purchased through Stock Connect, are considered speculative and subject to heightened risks in addition to the general risks of investing in foreign securities. Unlike more established markets, emerging markets may have less stable governments, less developed economies and their securities markets may be more concentrated and less liquid. In addition, the securities markets of emerging market countries may consist of companies with smaller market capitalizations and may suffer periods of relative illiquidity; significant price volatility; restrictions on foreign investment; and possible restrictions on repatriation of investment income and capital. In certain emerging markets, governments have historically exercised substantial control over the economy through administrative regulation and/or state ownership. Future economic or political crises could lead to price controls, forced mergers, expropriation or confiscatory taxation, seizure, nationalization or creation of government monopolies.

Active Management Risk – The Fund is subject to the risk that the Adviser’s judgments about the attractiveness, value, or potential appreciation of the Fund’s investments may prove to be incorrect. If the investments selected and strategies employed by the Fund fail to produce the intended results, the Fund could underperform in comparison to other funds with similar objectives and investment strategies.

Investment Style Risk – The Fund pursues a “growth style” of investing, meaning that the Fund invests in equity securities of companies that the Adviser believes will have above-average rates of relative earnings growth and which, therefore, may experience above-average increases in stock prices. Over time, a relative growth investing style may go in and out of favor, causing the Fund to sometimes underperform other equity funds that use differing investing styles.

Sector and Industry Focus Risk – Because the Fund may, from time to time, be more heavily invested in particular sectors or industries, the value of its shares may be especially sensitive to factors and economic risks that specifically affect those sectors or industries. As a result, the

6

Fund’s share price may at times fluctuate more widely than the value of shares of a mutual fund that invests in a broader range of sectors or industries.

Large Capitalization Company Risk – The large capitalization companies in which the Fund may invest may lag the performance of smaller capitalization companies because large capitalization companies may experience slower rates of growth than smaller capitalization companies and may not respond as quickly to market changes and opportunities.

Non-Diversification Risk – The Fund is classified as “non-diversified,” which means it may invest a larger percentage of its assets in a smaller number of issuers than a diversified fund. To the extent that the Fund invests its assets in a smaller number of issuers, the Fund will be more susceptible to negative events affecting those issuers than a diversified fund. However, the Fund intends to satisfy the asset diversification requirements for qualifying as a RIC under Subchapter M of the Code.

Geographic Focus Risk – To the extent that it focuses its investments in a particular country or geographic region, the Fund may be more susceptible to economic, political, regulatory or other events or conditions affecting issuers and countries within that country or geographic region. As a result, the Fund may be subject to greater price volatility and risk of loss than a fund holding more geographically diverse investments.

Investing in the United States Risk. The Fund focuses its investments in the United States. As a result, the Fund may be more susceptible to economic, political, regulatory or other events or conditions affecting issuers within the United States, and may be subject to greater price volatility and risk of loss, than a fund holding more geographically diverse investments.

De-Globalization Risk – The Fund’s investments leave the Fund potentially susceptible to acute headline risk associated with Sino-U.S. trade tensions and the broader trend of de-globalization across the globe. Nationalism in the U.S. and abroad is on the rise, which presents risks to global commerce and the companies engaged in such commerce. For example, nationalistic trade policies that favor domestic companies as opposed to foreign competitors may become more likely. Such policies may lead to global supply chain and market disruptions, which could have an adverse effect on the companies in which the Fund invests and the performance of the Fund.

Depositary Receipts Risk – Investments in depositary receipts may be less liquid and more volatile than the underlying securities in their

7

primary trading market. If a depositary receipt is denominated in a different currency than its underlying securities, the Fund will be subject to the currency risk of both the investment in the depositary receipt and the underlying security. Holders of depositary receipts may have limited or no rights to take action with respect to the underlying securities or to compel the issuer of the receipts to take action. The prices of depositary receipts may differ from the prices of securities upon which they are based. Certain of the depositary receipts in which the Fund invests may be unsponsored depositary receipts. Unsponsored depositary receipts are issued by one or more depositaries in response to market demand, but without a formal agreement with the company that issues the underlying securities. Unsponsored depositary receipts may not provide as much information about the underlying issuer and may not carry the same voting privileges as sponsored depositary receipts. In addition, prices of unsponsored depositary receipts may be more volatile than those of sponsored depositary receipts.

Stock Connect Investing Risk – Trading through Stock Connect is subject to a number of restrictions that may affect the Fund’s investments and returns, including a daily quota that limits the maximum net purchases under Stock Connect each day. In addition, investments made through Stock Connect are subject to relatively untested trading, clearance and settlement procedures. The Fund’s investments in A Shares purchased through Stock Connect are generally subject to Chinese securities regulations and listing rules and may only be sold or otherwise transferred through Stock Connect. While overseas investors currently are exempt from paying capital gains or value added taxes on income and gains from investments in A Shares purchased through Stock Connect, these tax rules could change, which could result in unexpected tax liabilities for the Fund. Stock Connect operates only on days when both the China and Hong Kong markets are open for trading and when banks in both markets are open on the corresponding settlement days. Therefore, the Fund may be subject to the risk of price fluctuations of A Shares when Stock Connect is not trading.

Foreign Currency Risk – As a result of the Fund’s investments in securities denominated in, and/or receiving revenues in, foreign currencies, the Fund will be subject to currency risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar, in which case the dollar value of an investment in the Fund would be adversely affected.

Small- and Mid-Capitalization Company Risk – The small- and mid-capitalization companies in which the Fund may invest may be more vulnerable to adverse business or economic events than larger, more

8

established companies. In particular, investments in these small- and mid-sized companies may pose additional risks, including liquidity risk, because these companies tend to have limited product lines, markets and financial resources, and may depend upon a relatively small management group. Therefore, small- and mid-cap stocks may be more volatile than those of larger companies. These securities may be traded over-the-counter or listed on an exchange.

Warrants Risk – Investments in warrants involve the risk of loss of the purchase value of a warrant if the right to subscribe to additional shares is not exercised prior to the warrant’s expiration. Also, the purchase of warrants involves the risk that the effective price paid for the warrant added to the subscription price of the underlying security may exceed the market price of the underlying security in instances such as those where there is no movement in the price of the underlying security.

Participation Notes Risk – The return on a P-Note is linked to the performance of the issuers of the underlying securities. The performance of P-Notes will not replicate exactly the performance of the issuers that they seek to replicate due to transaction costs and other expenses. P-Notes are subject to counterparty risk since the notes constitute general unsecured contractual obligations of the financial institutions issuing the notes, and the Fund is relying on the creditworthiness of such institutions and has no rights under the notes against the issuers of the underlying securities. In addition, P-Notes are subject to liquidity risk, which is described elsewhere in this section.

Large Purchase and Redemption Risk – Large purchases or redemptions of the Fund’s shares may force the Fund to purchase or sell securities at times when it would not otherwise do so, and may cause the Fund’s portfolio turnover rate and transaction costs to rise, which may negatively affect the Fund’s performance and have adverse tax consequences for Fund shareholders.

Liquidity Risk – Certain securities may be difficult or impossible to sell at the time and the price that the Fund would like. The Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on Fund management or performance.

IPO Risk – The market value of shares issued in an IPO 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 a company’s business model, quality of management, earnings growth potential, and other criteria used to evaluate its investment prospects. Accordingly, investments in IPO

9

shares involve greater risks than investments in shares of companies that have traded publicly on an exchange for extended periods of time. Investments in IPO shares may also involve high transaction costs, and are subject to market risk and liquidity risk, which are described elsewhere in this section.

Preferred Stock Risk – Preferred stocks in which the Fund may invest are sensitive to interest rate changes, and are also subject to equity risk, which is the risk that stock prices will fall over short or extended periods of time. The rights of preferred stocks on the distribution of a company’s assets in the event of a liquidation are generally subordinate to the rights associated with a company’s debt securities.

ETF Risk – ETFs are pooled investment vehicles, such as registered investment companies and grantor trusts, whose shares are listed and traded on U.S. and non-U.S. stock exchanges or otherwise traded in the over-the-counter market. To the extent that the Fund invests in ETFs, the Fund will be subject to substantially the same risks as those associated with the direct ownership of the securities in which the ETF invests, and the value of the Fund’s investment will fluctuate in response to the performance of the ETF’s holdings. ETFs typically incur fees that are separate from those of the Fund. Accordingly, the Fund’s investments in ETFs will result in the layering of expenses such that shareholders will indirectly bear a proportionate share of the ETFs’ operating expenses, in addition to paying Fund expenses.

U.S. Treasury Securities Risk – A security backed by the U.S. Treasury or the full faith and credit of the United States is guaranteed only as to the timely payment of interest and principal when held to maturity, but the market prices for such securities are not guaranteed and will fluctuate.

Commodities Risk – The prices of physical commodities (such as energy, metals, minerals, or agricultural products) may be affected by factors such as natural disasters, weather, and U.S. and international economic, political and regulatory developments. The prices of commodities can also fluctuate due to supply and demand disruptions in major producing or consuming regions, as well as temporary distortions in the commodities markets due to, among other factors, lack of liquidity, the participation of speculators, and government regulation and other actions.
