Example

The example below is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. This 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 each period. The example also assumes that your investment has a 5% annual 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
Institutional Shares	$70	$221	$384	$859
Investor Shares	$86	$268	$466	$1,037
Advisor Shares	$111	$347	$601	$1,329

Portfolio Turnover


Summary Section – Brown Advisory Growth Equity Fund

During the most recent fiscal year, the portfolio turnover rate for the Fund was 21% of the average value of its portfolio.

Principal Investment Strategies

Under normal conditions, Brown Advisory LLC (the “Adviser”) seeks to achieve the Fund’s investment objective by investing at least 80% of the value of its net assets (plus any borrowings for investment purposes) in equity securities of domestic companies. The Fund invests primarily in securities of medium and large market capitalization companies that the Adviser believes have exhibited an above average rate of earnings growth and that have prospects for above average, sustainable growth in the future. Medium and large market capitalization companies are, according to the Adviser, those companies with market capitalizations generally greater than $2 billion at the time of purchase. The Fund may also invest in companies that do not exhibit particularly strong earnings histories but have other attributes that may contribute to accelerated growth in the foreseeable future. Equity securities include domestic common and preferred stock, convertible debt securities, American Depositary Receipts (“ADRs”), real estate investment trusts (“REITs”) and exchange traded funds (“ETFs”). The Fund may also invest in private placements in these types of securities. The Fund invests primarily in ETFs that have an investment objective similar to the Fund’s or that otherwise are permitted investments with the Fund’s investment policies described herein. ADRs are equity securities traded on U.S. securities exchanges, which are generally issued by banks or trust companies to evidence ownership of foreign equity securities. The Fund may invest up to 15% of its net assets in foreign securities, including in emerging markets.

The Adviser may sell a security or reduce its position if:

•The investment thesis is violated;

•A more attractively priced security is found; or

•The security becomes overvalued relative to the long-term expectation.

In order to respond to adverse market, economic, political, or other conditions, the Fund may assume a temporary defensive position that is inconsistent with its investment objective and principal investment strategy and invest without limit in cash and prime quality cash equivalents such as prime commercial paper and other money market instruments. A defensive position, taken at the wrong time, may have an adverse impact on the Fund’s performance. The Fund may be unable to achieve its investment objective during the employment of a temporary defensive measure.

Principal Investment Risks

As with all mutual funds, there is the risk that you could lose all or a portion of your investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. The following are the principal risks that could affect the value of your investment:

•American Depositary Receipts (“ADRs”) and Global Depository Receipts (“GDRs”) Risk. ADRs and GDRs may be subject to some of the same risks as direct investment in foreign companies, which includes international trade, currency, political, regulatory and diplomatic risks. In a sponsored ADR arrangement, the foreign issuer assumes the obligation to pay some or all of the depositary’s transaction fees. Under an unsponsored ADR arrangement, the foreign issuer assumes no obligations and the depositary’s transaction fees are paid directly by the ADR holders. Because unsponsored ADR arrangements are organized independently and without the cooperation of the issuer of the underlying securities, available information concerning the foreign issuer may not be as current as for sponsored ADRs and voting rights with respect to the deposited securities are not passed through. GDRs can involve currency risk since, unlike ADRs, they may not be U.S. dollar-denominated.

•Convertible Securities Risk. The value of convertible securities tends to decline as interest rates rise and, because of the conversion feature, tends to vary with fluctuations in the market value of the underlying securities.


Summary Section – Brown Advisory Growth Equity Fund

reporting and recordkeeping requirements that are as robust as those in more developed countries, and therefore, material information about a company may be unavailable or unreliable, and U.S. regulators may be unable to enforce a company’s regulatory obligations. Emerging markets countries are often particularly sensitive to market movements because their market prices tend to reflect speculative expectations. Low trading volumes may result in a lack of liquidity and in extreme price volatility. Investors should be able to tolerate sudden, sometimes substantial, fluctuations in the value of their investments. Emerging market countries may have policies that restrict investment by foreigners or that prevent foreign investors from withdrawing their money at will.

•Equity and General Market Risk. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value. The stock market may experience declines or stocks in the Fund’s portfolio may not increase their earnings at the rate anticipated. The Fund’s NAV and investment return will fluctuate based upon changes in the value of its portfolio securities. Markets may, in response to economic or market developments, governmental actions or intervention, natural disasters, epidemics, pandemics or other external factors, experience periods of high volatility and reduced liquidity. During those periods, the Fund may experience high levels of shareholder redemptions, and may have to sell securities at times when the Fund would otherwise not do so, potentially at unfavorable prices. Certain securities, particularly fixed income securities, may be difficult to value during such periods.

•ETF Risk. ETFs may trade at a discount to the aggregate value of the underlying securities and although expense ratios for ETFs are generally low, frequent trading of ETFs by the Fund can generate brokerage expenses. Shareholders of the Fund will indirectly be subject to the fees and expenses of the individual ETFs in which the Fund invests.

•Foreign Securities Risk. The Fund may invest in foreign securities and is subject to risks associated with foreign markets, such as adverse political, social and economic developments such as war, political instability, hyperinflation, currency devaluations, and overdependence on particular industries; accounting standards or governmental supervision that is not consistent with that to which U.S. companies are subject; limited information about foreign companies; less liquidity and higher volatility in foreign markets and less protection to the shareholders in foreign markets. In addition, investments in certain foreign markets that have historically been considered stable may become more volatile and subject to increased risk due to ongoing developments and changing conditions in such markets. The value of the Fund’s foreign investments may also be affected by foreign tax laws, special U.S. tax considerations and restrictions on receiving the investment proceeds from a foreign country. Dividends or interest on, or proceeds from the sale or disposition of, foreign securities may be subject to non-U.S. withholding or other taxes. Economic sanctions could, among other things, effectively restrict or eliminate the Fund’s ability to purchase or sell securities or groups of securities for a substantial period of time, and may make the Fund’s investments in such securities harder to value.

•Growth Company Risk. Securities of growth companies can be more sensitive to the company’s earnings and more volatile than the market in general.

•Large Capitalization Company Risk. Large capitalization companies may be unable to respond quickly to new competitive challenges like changes in consumer tastes or innovative smaller competitors. Also, large capitalization companies are sometimes unable to attain the high growth rates of successful, smaller companies, especially during extended periods of economic expansion.

•Management Risk. The Fund may not meet its investment objective based on the Adviser’s success or failure to implement investment strategies for the Fund.

•Medium Capitalization Company Risk. Securities of medium sized companies may be more volatile and more difficult to liquidate during market down turns than securities of larger companies. Additionally the price of medium-sized companies may decline more in response to selling pressures.

•Private Placement Risk. The Fund may invest in privately issued securities of domestic common and preferred stock, convertible debt securities, ADRs and REITs, including those which may be resold only in accordance with Rule 144A under the Securities Act of 1933, as amended. Privately issued securities are restricted securities that are not publicly traded. Delay or difficulty in selling such securities may result in a loss to the Fund.


Summary Section – Brown Advisory Growth Equity Fund

•REIT and Real Estate Risk. The value of the Fund’s investments in REITs may change in response to changes in the real estate market such as declines in the value of real estate, lack of available capital or financing opportunities, and increases in property taxes or operating costs. In connection with the Fund’s investments in REITs, the Fund is also subject to risks associated with extended vacancies of properties or defaults by borrowers or tenants, particularly during periods of disruptions to business operations or an economic downturn.

Performance Information

Summary Section – Brown Advisory Growth Equity Fund

After-tax returns are calculated using the historical highest individual Federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. In certain cases, the figure representing “Return after Taxes on Distributions and Sale of Fund Shares” may be higher than the other return figures for the same period, since a higher after-tax return results when a capital loss occurs upon redemption and provides an assumed tax deduction that benefits the investor. After-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts. After-tax returns are shown for Investor Shares only. After-tax returns for Advisor Shares and Institutional Shares will vary.

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, the portfolio turnover rate for the Fund was 12% of the average value of its portfolio.


Summary Section – Brown Advisory Flexible Equity Fund

Principal Investment Strategies

Under normal conditions, Brown Advisory LLC (the “Adviser”) seeks to achieve the Fund’s investment objective by investing at least 80% of the value of its net assets (plus any borrowings for investment purposes) in a diversified portfolio of equity securities. The Fund invests primarily in securities of medium and large market capitalization companies that the Adviser believes have strong, or improving, long-term business characteristics and share prices that do not reflect these favorable fundamental attributes. Medium and large market capitalization companies are, according to the Adviser, those companies with market capitalizations generally greater than $2 billion at the time of purchase. Equity securities include domestic and foreign common and preferred stock, convertible debt securities, American Depositary Receipts (“ADRs”), real estate investment trusts (“REITs”), exchange traded funds (“ETFs”), and other types of investment companies. The Fund may also invest in private placements in these types of securities. The Fund may invest in ETFs and other types of investment companies that have an investment objective similar to the Fund’s or that otherwise are permitted investments with the Fund’s investment policies described herein. ADRs are equity securities traded on U.S. securities exchanges, which are generally issued by banks or trust companies to evidence ownership of foreign equity securities. The Fund may invest up to 15% of its net assets in foreign securities, including emerging markets.

The Adviser follows an investment philosophy referred to as “flexible equity.” Flexibility allows the Adviser to look at many types of opportunities expanding the bargain hunting concepts of value investing to a broad range of opportunities. The Adviser emphasizes individual security selection based on identifying long-term attractive businesses, i.e., those with significant desirable traits and few or no undesirable traits, when they are available at bargain prices. Desirable traits include favorable business economics supported by enduring competitive advantages, capable and trustworthy management, positive industry dynamics and sensible capital allocation. Bargain prices most often arise in the stock market due to short-term investor perceptions or temporary business challenges creating undue price declines and price recovery potential, or unrecognized favorable prospects within a business or changes for the better in company management or industry conditions.

With respect to 20% of its assets, the Fund may invest in investment grade securities or unrated securities determined by the Adviser to be of comparable quality.

The sale of a company’s equity securities may arise if the securities’ market price exceeds the Adviser’s estimate of intrinsic value, if the ratio of risk and rewards of continuing to own the company’s equity is no longer attractive, or if the Adviser needs to raise cash to purchase a more attractive investment opportunity, satisfy net redemptions, or other purposes.

Principal Investment Risks


Summary Section – Brown Advisory Flexible Equity Fund

•Debt/Fixed Income Securities Risk. An increase in interest rates typically causes a fall in the value of the debt securities in which the Fund may invest. Over the past several years, the Federal Reserve has maintained the level of interest rates at or near historic lows, however, more recently, interest rates have begun to increase as a result of action that has been taken by the Federal Reserve which has raised, and may continue to raise, interest rates, which may negatively impact the Fund’s performance or otherwise adversely impact the Fund. The value of your investment in the Fund may change in response to changes in the credit ratings of the Fund’s portfolio of debt securities. Moreover, rising interest rates or lack of market participants may lead to decreased liquidity in the bond and loan markets, making it more difficult for the Fund to sell its holdings at a time when the Fund’s manager might wish to sell. Lower rated securities (“junk bonds”) are generally subject to greater risk of loss of your money than higher rated securities. Issuers may (increase) decrease prepayments of principal when interest rates (fall) increase, affecting the maturity of the debt security and causing the value of the security to decline.

•Emerging Markets Risk. The Fund may invest in emerging markets, which may carry more risk than investing in developed foreign markets. Risks associated with investing in emerging markets include limited information about companies in these countries, greater political and economic uncertainties compared to developed foreign markets, underdeveloped securities markets and legal systems, potentially high inflation rates, and the influence of foreign governments over the private sector. In addition, companies in emerging market countries may not be subject to accounting, auditing, financial reporting and recordkeeping requirements that are as robust as those in more developed countries, and therefore, material information about a company may be unavailable or unreliable, and U.S. regulators may be unable to enforce a company’s regulatory obligations. Emerging markets countries are often particularly sensitive to market movements because their market prices tend to reflect speculative expectations. Low trading volumes may result in a lack of liquidity and in extreme price volatility. Investors should be able to tolerate sudden, sometimes substantial, fluctuations in the value of their investments. Emerging market countries may have policies that restrict investment by foreigners or that prevent foreign investors from withdrawing their money at will.


Summary Section – Brown Advisory Flexible Equity Fund

•Management Risk. The Fund may not meet its investment objective based on the Adviser’s success or failure to implement investment strategies for the Fund.

•Non-Investment Grade ("Junk Bond") Securities Risk. Securities rated below investment grade, i.e., Ba or BB and lower (“junk bonds”), are subject to greater risks of loss of your money than higher rated securities. Compared with issuers of investment grade fixed-income securities, junk bonds are more likely to encounter financial difficulties and to be materially affected by these difficulties.

•Smaller Capitalization Company Risk. Securities of smaller sized companies may be more volatile and more difficult to liquidate during market down turns than securities of larger companies. Additionally the price of smaller companies may decline more in response to selling pressures.

•Value Company Risk. The stock of value companies can continue to be undervalued for long periods of time and not realize its expected value. The value of the Fund may decrease in response to the activities and financial prospects of an individual company.

Principal Investment Strategies

The Brown Advisory Sustainable Growth Fund seeks to achieve capital appreciation. To achieve its objective, the Fund invests at least 80% of the value of its net assets (plus any borrowings for investment purposes) in equity securities of domestic companies that meet the sustainable investment criteria of the Fund, collectively the “Investment Criteria.” The Fund invests primarily in the securities of medium and large capitalization companies that Brown Advisory LLC (the “Adviser”) believes (1) have the fundamental strengths (strong financials and business models) to outperform their peers and deliver strong earnings growth over a market cycle, (2) effectively implement Sustainable Business Advantages (described below), and (3) have attractive valuations.

The Adviser seeks companies with strong business models and prospects for growth, strong cash flow generation, and a solid track record of execution, among other qualities. Through investment analysis the Adviser also seeks companies with Sustainable Business Advantages, defined as companies that use internal sustainability strategies to improve their financial position, including but not limited to, those strategies that lead to revenue growth, cost improvements, or enhanced franchise value. The Adviser also seeks companies that have strong risk management practices in place where sustainability-related risks may be present.

Additionally, while driving impact is not an input to the investment thesis, the Adviser often finds an overlap between Sustainable Business Advantage with positive sustainability outcomes.

The Adviser pursues strategic engagement with companies and other stakeholders in an effort to enhance due diligence and monitor the investment thesis.

The Adviser considers each proxy voting proposal related to holdings in the Fund on its own merits and an independent determination is made based on the relevant facts and circumstances, in accordance with the Adviser’s current Proxy Voting Policy.

Medium and large capitalization companies are, according to the Adviser, those companies with market capitalizations generally greater than $2 billion at time of purchase. The Fund may also invest a portion of the portfolio in equity securities of small market capitalization companies. The equity securities in which the Fund principally invests are common stocks. Furthermore, the Fund may invest up to 15% of assets in foreign securities (including American Depositary Receipts (“ADRs”)), which may include emerging markets securities. ADRs may be either sponsored or unsponsored. The Fund also may invest in real estate investment trusts (“REITs”).

The Adviser uses scenario analyses to assess the company’s valuation and potential for appreciation or downside risk.

The Adviser may sell a security or reduce its position for a number of reasons, including:

•The investment thesis is violated;

•A more attractively priced security is found; or

•The security becomes overvalued relative to the Adviser’s long-term expectations.

Principal Investment Risks


Summary Section – Brown Advisory Sustainable Growth Fund

•Growth Company Risk. Securities of growth companies can be more sensitive to the company’s earnings and more volatile than the market in general.


Summary Section – Brown Advisory Sustainable Growth Fund

•Management Risk. The Fund may not meet its investment objective based on the Adviser’s success or failure to implement investment strategies for the Fund.

•Smaller and Medium Capitalization Company Risk. Securities of smaller and medium sized companies may be more volatile and more difficult to liquidate during market down turns than securities of larger companies. Additionally the price of smaller companies may decline more in response to selling pressures.

•Sustainability Policy Risk. The Fund’s consideration of sustainability criteria could cause it to make or avoid investments that could result in the Fund underperforming similar funds that do not consider such sustainability criteria.

The Fund may have Total Annual Fund Operating Expenses after Fee Waiver and/or Expense Reimbursement higher than these expense caps as a result of any acquired fund fees and expenses or other expenses that are excluded from the calculation. The contractual waivers and expense reimbursements may be changed or eliminated at any time by the Board of Trustees, on behalf of the Fund, upon 60 days written notice to the Adviser. The contractual waivers and expense reimbursements may not be terminated by the Adviser without the consent of the Board of Trustees. The Adviser may recoup any waived amount from the Fund pursuant to this agreement if such reimbursement does not cause the Fund to exceed existing expense limitations or the limitations in place at the time the reduction was originally made and the reimbursement is made within three years after the date on which the Adviser incurred the expense.

The example below is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. This 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 each period. The example also assumes that your investment has a 5% annual return each year and that the Fund’s operating expenses remain the same (taking into account the contractual expense limitation being in effect for the period through October 31, 2024).

Principal Investment Strategies

Under normal conditions, the Adviser seeks to achieve the Fund’s investment objective by investing at least 80% of the value of its net assets (plus any borrowings for investment purposes) in equity securities of mid-cap domestic companies. The Adviser considers mid-cap companies to be those with market capitalizations that fall within the range of the market capitalizations of companies in the Russell Midcap® Growth Index. As of September 30, 2023, the range was from $223.4 million to $53.044 billion dollars. Market capitalization is measured at the time of purchase. The Fund invests primarily in companies the Adviser believes have above average growth prospects.

The Adviser conducts an in-depth analysis of a company’s fundamentals to identify those companies it believes have the potential to compound earnings at an above-average rate for an extended period of time. The Fund invests primarily in companies the Adviser believes possess “3G” criteria: durable growth, sound governance, and scalable go-to-market strategies. In considering durable growth, the Adviser assesses whether there is a large and growing market, whether the company is a market leader and/or is gaining market share, and whether a company has a differentiated product offering. The Adviser examines a company’s governance characteristics including the strength of management, whether there is a shareholder-friendly board, and whether there is an aligned incentive system between management and shareholders. Finally, the Adviser evaluates whether a company’s go-to-market strategies will result in incremental revenue, high and/or rising margins, and the efficient use of capital.

Equity securities include domestic common and preferred stock, convertible debt securities, American Depositary Receipts (“ADRs”), real estate investment trusts (“REITs”), exchange traded funds (“ETFs”), and other types of investment companies. The Fund may also invest in private placements in these types of securities. The Fund may invest in ETFs and other types of investment companies that have an investment objective similar to the Fund’s or that otherwise are permitted investments with the Fund’s investment policies described herein. ADRs are equity securities traded on U.S. securities exchanges, which are generally issued by banks or trust companies to evidence ownership of foreign equity securities. The Fund may invest up to 20% of its net assets in foreign securities.

The Adviser may sell a security or reduce its position if it believes:

•The security subsequently fails to meet initial investment criteria;

•A more attractively priced security is found; or

•The security becomes overvalued relative to the long-term expectation.


Summary Section – Brown Advisory Mid-Cap Growth Fund

Principal Investment Risks

•Growth Company Risk. Securities of growth companies can be more sensitive to the company’s earnings and more volatile than the market in general.


Summary Section – Brown Advisory Mid-Cap Growth Fund

•Liquidity Risk. Certain securities held by the Fund may be difficult (or impossible) to sell at the time and at the price the Adviser would like. As a result, the Fund may have to hold these securities longer than it would like and may forego other investment opportunities. There is the possibility that the Fund may lose money or be prevented from realizing capital gains if it cannot sell a security at a particular time and price.

•Management Risk. The Fund may not meet its investment objective based on the Adviser’s success or failure to implement investment strategies for the Fund.

•Medium Capitalization Company Risk. Securities of medium capitalization companies may be more volatile and more difficult to liquidate during market down turns than securities of larger companies. Additionally the price of medium-sized companies may decline more in response to selling pressures.

securities markets and legal systems, potentially high inflation rates, and the influence of foreign governments over the private sector. In addition, companies in emerging market countries may not be subject to accounting, auditing, financial reporting and recordkeeping requirements that are as robust as those in more developed countries, and therefore, material information about a company may be unavailable or unreliable, and U.S. regulators may be unable to enforce a company’s regulatory obligations. Emerging markets countries are often particularly sensitive to market movements because their market prices tend to reflect speculative expectations. Low trading volumes may result in a lack of liquidity and in extreme price volatility. Investors should be able to tolerate sudden, sometimes substantial, fluctuations in the value of their investments. Emerging market countries may have policies that restrict investment by foreigners or that prevent foreign investors from withdrawing their money at will.

•Growth Company Risk. Securities of growth companies can be more sensitive to the company’s earnings and more volatile than the market in general.

•Management Risk. The Fund may not meet its investment objective based on the Adviser’s success or failure to implement investment strategies for the Fund.

•Smaller Company Risk. Securities of companies smaller than larger companies may be more volatile and as a result, the price of smaller companies may decline more in response to selling pressure.

Principal Investment Strategies

Under normal conditions, Brown Advisory LLC (the “Adviser”) seeks to achieve the Fund’s investment objective by investing at least 80% of the value of its net assets (plus any borrowings for investment purposes) in equity securities of small capitalization companies. Equity securities include common stock, preferred stock, equity-equivalent securities such as convertible securities, stock futures contracts, equity options, other investment companies, American Depositary Receipts (“ADRs”), real estate investment trusts (“REITs”) and exchange traded funds (“ETFs”), and the Fund may also invest in private placements in these types of securities. Small companies, according to the Adviser, are companies whose market capitalizations are generally less than $6 billion or the maximum capitalization of companies in the Russell 2000® Value Index (which was approximately $8.112 billion as of September 30, 2023), whichever is greater, at the time of purchase. The Fund invests primarily in equity securities that trade in the U.S. securities markets and that the Adviser believes are undervalued, broadly defined as trading at a discount to the estimated economic value of a company’s underlying business. The Adviser uses a research-driven analysis that results in the Fund’s portfolio having an emphasis on out-of-favor or under-followed, cash-generating companies with sustainable business models, strong finances, competent management and a demonstrable record of profitability and self-funded growth. The Fund may also invest in cyclical companies or companies that have experienced a temporary setback if the valuation of the company is at an appropriate discount to the long-term earnings potential of the company. To a more limited extent, the Fund may invest up to 15% of its assets in foreign equity securities, including equity securities from emerging markets. With respect to 20% of its assets, the Fund may also invest in foreign or domestic debt securities, including up to 5% of its assets in distressed debt securities. The Fund may utilize options, futures contracts and options on futures. These investments will typically be made for investment purposes consistent with the Fund’s investment objective and may also be used to mitigate or hedge risks within the portfolio or for the temporary investment of cash balances. By investing in derivatives, the Fund attempts to achieve the economic equivalence it would achieve if it were to invest directly in the underlying security. Investments in derivatives may be counted towards the Fund’s 80% investment policy if they have economic characteristics similar to the other investments that are included in the Fund’s 80% investment policy. The Fund intends to use the mark-to-market value of such derivatives for purposes of complying with the Fund’s 80% investment policy.

The Fund invests primarily in ETFs that have an investment objective similar to the Fund’s or that otherwise are permitted investments with the Fund’s investment policies described herein. ADRs are equity securities traded on U.S. securities exchanges, which are generally issued by banks or trust companies to evidence ownership of foreign equity securities.

The Adviser may sell a security or reduce its position if:

•It has reached its target price;

•Its present reward to risk ratio is unattractive;

•It is overvalued; or

•The company’s fundamentals have deteriorated in a material, long-term manner.

Principal Investment Risks


Summary Section – Brown Advisory Small-Cap Fundamental Value Fund

deposited securities are not passed through. GDRs can involve currency risk since, unlike ADRs, they may not be U.S. dollar-denominated.

•Derivatives Risk. The risk that an investment in derivatives will not perform as anticipated, cannot be closed out at a favorable time or price, or will increase the Fund’s volatility; that derivatives may create investment leverage; that, when a derivative is used as a substitute or alternative to a direct cash investment, the transaction may not provide a return that corresponds precisely with that of the cash investment; that a derivative will not perform in the manner anticipated by the Adviser, which may result in losses that partially or completely offset gains in portfolio positions; or that, when used for hedging purposes, derivatives will not provide the anticipated protection, causing the Fund to lose money on both the derivatives transaction and the exposure the Fund sought to hedge. The risks of investing in derivative instruments also include leverage, liquidity, market, credit, operational and legal risks. Additionally, any derivatives held by the Fund will have counterparty associated risks, which are the risks that the other party to the derivative contract, which may be a derivatives exchange, will fail to make required payments or otherwise fail to comply with the terms of the contract. The Fund potentially could lose all or a large portion of its investment in the derivative instrument.


Summary Section – Brown Advisory Small-Cap Fundamental Value Fund

•Investments in Other Investment Companies Risk. Shareholders of the Fund will indirectly be subject to the fees and expenses of the other investment companies in which the Fund invests, and these fees and expenses are in addition to the fees and expenses that Fund shareholders directly bear in connection with the Fund’s own operations. In addition, shareholders will be exposed to the investment risks associated with investments in the other investment companies.

•Management Risk. The Fund may not meet its investment objective based on the Adviser’s success or failure to implement investment strategies for the Fund.

•Smaller Company Risk. Securities of companies smaller than larger companies may be more volatile and as a result, the price of smaller companies may decline more in response to selling pressure.

Principal Investment Strategies

Equity securities include domestic common and preferred stock, equity-equivalent securities such as convertible securities, stock futures contracts, equity options, other investment companies, American Depositary Receipts (“ADRs”), real estate investment trusts (“REITs”) and exchange traded funds (“ETFs”). The Fund may also invest in private placements in these types of securities. The Fund may invest in ETFs that have an investment objective similar to the Fund’s or that otherwise are permitted investments with the Fund’s investment policies described herein. ADRs are equity securities traded on U.S. securities exchanges, which are generally issued by banks or trust companies to evidence ownership of foreign equity securities. The Fund may invest up to 20% of its net assets in foreign securities, including in emerging markets.

The Fund will invest primarily in securities the Adviser believes have strong business fundamentals and attractive valuations. The Adviser seeks securities with established or improving sustainability characteristics, defined as companies that use internal sustainability strategies to improve their financial position. The Adviser seeks companies with low exposure to sustainability risks, or that have strong risk management practices in place where these risks may by present.

The Adviser pursues strategic engagement with companies and other stakeholders in an effort to enhance due diligence and monitor the investment thesis.

The Adviser considers each proxy voting proposal related to holdings in the Fund on its own merits and an independent determination is made based on the relevant facts and circumstances, in consideration of the Adviser’s current Proxy Voting Policy.

The Adviser may sell a security or reduce its position if it believes:

•The security subsequently fails to meet initial Investment Criteria;

•A more attractively priced security is found; or

•The security becomes overvalued relative to the long-term expectation.

Example

The example below is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. This 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 each period. The example also assumes that your investment has a 5% annual return each year and that the Fund’s operating expenses remain the same (taking into account the contractual expense limitation being in effect for the period through October 31, 2024). 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
Institutional Shares	$73	$328	$604	$1,390
Investor Shares	$88	$375	$684	$1,560
Advisor Shares	$113	$453	$816	$1,839

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 period from the Fund’s inception on February 28, 2023 to the fiscal period ended June 30, 2023, the portfolio turnover rate for the Fund was 7% of the average value of its portfolio.

Principal Investment Strategies

Under normal conditions, Brown Advisory LLC (the “Adviser”) seeks to achieve the Fund’s investment objective by investing at least 80% of the value of its net assets (plus any borrowings for investment purposes) in equity securities that satisfy the Fund’s sustainable investment criteria. The Fund invests primarily in securities of large market capitalization companies that the Adviser deems to meet its “value” and “sustainable investment” criteria, collectively the “Investment Criteria” for the Fund. Large market capitalization companies are, according to the Adviser, those companies with market capitalizations generally greater than $3 billion at the time of purchase. The market capitalizations of the companies in the Fund’s portfolio changes over time; the Fund will not automatically sell or cease to purchase stock of a company it already owns just because the company’s market capitalization falls outside this range.

Equity securities include common stock, preferred stock, equity-equivalent securities such as convertible securities, stock futures contracts, equity options, other investment companies, American Depositary Receipts (“ADRs”), real estate investment trusts (“REITs”) and exchange traded funds (“ETFs”). The Fund may also invest in private placements in these types of securities. The Fund may invest in ETFs that have an investment objective similar to the Fund’s or that otherwise are permitted investments with the Fund’s investment policies described herein. ADRs are equity securities traded on U.S. securities exchanges, which are generally issued by banks or trust companies to evidence ownership of foreign equity securities. The Fund may invest up to 20% of its assets in foreign securities, including in emerging markets. Emerging market countries for these purposes consists of countries in Latin America, Asia, Eastern Europe, Africa and the Middle East, and include, among other countries, Brazil, China, Hong Kong, India, Indonesia and Taiwan.

The Adviser defines “value” as durable free cash flow businesses that exhibit capital discipline and trade at attractive free cashflow yields. The Fund invests primarily in equity securities that trade in the U.S. securities markets and that the Adviser believes are undervalued, broadly defined as trading at a discount to the estimated economic value of a company’s underlying business. The Adviser uses a research-driven analysis that results in the Fund’s portfolio having an emphasis on out-of-favor, cash-generating companies with durable business models, strong finances, competent management and a demonstrable record of prudent capital allocation. The Fund may also invest in cyclical companies or companies that have experienced a temporary setback if the valuation of the company is at an appropriate discount to the long-term earnings potential of the company.

The Adviser defines its sustainable investment criteria as companies that have sustainability characteristics that may improve their financial position and have strong management of sustainability-related risks. The Adviser looks for companies with Sustainable Cash Flow Advantage (“SCFA”) over time. SCFA is part of the broader research process. A majority of the Fund will consist of securities with established or emerging SCFA. SCFA’s have one or more of the following drivers:

•People: For example:

•Attraction, retention and internal promotion of employees drives cost savings while also creating a cultural advantage.


Summary Section- Brown Advisory Sustainable Value Fund

•Leadership on diversity, equity and inclusion has the potential to serve as both a mechanism for improved employee management and generation of revenue tied to innovation.

•Process: For example:

•Sound operations that promote a safe and healthy community can bolster franchise value, while also avoiding regulatory and reputational risk.

•Margin improvement through operations that save costs and resources, enabling meaningful reduction in carbon emissions and natural capital.

•Product: For example:

•Products or services that provide superior customer outcomes resulting in recurring revenue while also providing environmental and/or social solutions.

Additionally, the Adviser pursues strategic engagement with companies and other stakeholders in an effort to enhance due diligence and monitor the investment thesis, including emerging SCFA.

The Adviser considers each proxy voting proposal related to holdings in the Fund on its own merits and an independent determination is made based on the relevant facts and circumstances, in consideration of the Adviser’s current Proxy Voting Policy.

Principal Investment Risks

•American Depositary Receipts and Global Depository Receipts Risk. ADRs and GDRs may be subject to some of the same risks as direct investment in foreign companies, which includes international trade, currency, political, regulatory and diplomatic risks. In a sponsored ADR arrangement, the foreign issuer assumes the obligation to pay some or all of the depositary’s transaction fees. Under an unsponsored ADR arrangement, the foreign issuer assumes no obligations and the depositary’s transaction fees are paid directly by the ADR holders. Because unsponsored ADR arrangements are organized independently and without the cooperation of the issuer of the underlying securities, available information concerning the foreign issuer may not be as current as for sponsored ADRs and voting rights with respect to the deposited securities are not passed through. GDRs can involve currency risk since, unlike ADRs, they may not be U.S. dollar-denominated.


Summary Section- Brown Advisory Sustainable Value Fund

substantial, fluctuations in the value of their investments. Emerging market countries may have policies that restrict investment by foreigners or that prevent foreign investors from withdrawing their money at will.

•Large Capitalization Company Risk. Large capitalization companies may be unable to respond quickly to new competitive challenges like changes in consumer tastes or innovative smaller competitors. In addition, large capitalization companies are sometimes unable to attain the high growth rates of successful, smaller companies, especially during extended periods of economic expansion.

•Liquidity Risk. Certain securities held by the Fund may be difficult (or impossible) to sell at the time and at the price the Fund would like. As a result, the Fund may have to hold these securities longer than it would like and may forego other investment opportunities. There is the possibility that the Fund may lose money or be prevented from realizing capital gains if it cannot sell a security at a particular time and price.

•Management Risk. The Fund may not meet its investment objective based on the Adviser’s success or failure to implement investment strategies for the Fund.

•New Fund Risk. The Fund is new with a limited operating history and there can be no assurance that the Fund will grow to or maintain an economically viable size.

•Private Placement Risk. The Fund may invest in privately issued securities of foreign common and preferred stock, convertible debt securities, ADRs, REITs and ETFs, including those which may be resold only in accordance with Rule 144A under the Securities Act of 1933, as amended. Privately issued securities are restricted securities that are not publicly traded. Delay or difficulty in selling such securities may result in a loss to the Fund.


Summary Section- Brown Advisory Sustainable Value Fund

•Valuation Risk. The prices provided by pricing services or independent dealers or the fair value determinations made by the Adviser may be different from the prices used by other mutual funds or from the prices at which securities are actually bought and sold. The prices of certain securities provided by pricing services may be subject to frequent and significant change, and will vary depending on the information that is available.

•Value Company Risk. The stock of value companies can continue to be undervalued for long periods of time and not realize its expected value. The value of investing primarily in value-oriented securities may decrease in response to the activities and financial prospects of an individual company.
