Summary Section

Brown Advisory Growth Equity Fund

Institutional Shares (BAFGX)

Investor Shares (BIAGX)

Advisor Shares (BAGAX)

Investment Objective

The Brown Advisory Growth Equity Fund (the “Fund”) seeks to achieve capital appreciation by primarily investing in equity securities.

Fees and Expenses

The following table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below.


Shareholder Fees (fees paid directly from your investment)	Institutional Shares	Investor Shares	Advisor Shares
Maximum Sales Charge (Load) imposed on Purchases (as a % of the offering price)	None	None	None
Maximum Deferred Sales Charge (Load) imposed on Redemptions (as a % of the sale price)	None	None	None
Redemption Fee (as a % of amount redeemed on shares held for 14 days or less)	1.00%	1.00%	1.00%
Exchange Fee (as a % of amount exchanged on shares held for 14 days or less)	1.00%	1.00%	1.00%

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
Management Fees	0.57%	0.57%	0.57%
Distribution and Service (12b-1) Fees	0.00%	0.00%	0.25%
Shareholder Servicing Fees	0.00%	0.15%	0.15%
Other Expenses	0.09%	0.09%	0.09%
Total Annual Fund Operating Expenses	0.66%	0.81%	1.06%

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	$67	$211	$368	$822
Investor Shares	$83	$259	$450	$1,002
Advisor Shares	$108	$337	$585	$1,294

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 21% of the average value of its portfolio.


Summary Section – Brown Advisory Growth 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 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

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.

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

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

•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. 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.

•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.

•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.

•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.

Performance Information

The Fund is the successor to the investment performance of the Brown Advisory Flexible Value Fund (the “Predecessor Fund”) as a result of the reorganization of the Predecessor Fund into the Fund on October 19, 2012. Accordingly, the performance information shown below for periods prior to October 19, 2012 is that of the Predecessor Fund. The Predecessor Fund was also advised by the Adviser and had the same investment objective and strategies as the Fund.

(1)Brown Advisory LLC (the "Adviser") has contractually agreed to waive its fees and/or reimburse certain expenses (exclusive of any front-end or contingent deferred sales loads, taxes, interest, brokerage commissions, acquired fund fees and expenses, expenses incurred in connection with any merger or reorganization and extraordinary expenses) in order to limit the Total Annual Fund Operating Expenses after Fee Waiver and/or Expense Reimbursement for Institutional Shares, Investor Shares and Advisor Shares to 0.76%, 0.91% and 1.16%, respectively, of the Fund’s average daily net assets through October 31, 2023. 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.

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, 2023). 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	$78	$249	$436	$975
Investor Shares	$93	$297	$517	$1,152
Advisor Shares	$118	$375	$651	$1,441

Portfolio Turnover

The Fund pays transaction costs, such as commissions and dealer mark-ups, 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 11% of the average value of its portfolio.

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 a diversified portfolio of dividend paying equity securities. The Adviser may invest in securities of companies of various market capitalizations but will focus on medium and large capitalization companies. Medium and large market capitalization companies are, according to the Adviser, those companies with market capitalizations of greater than $2 billion at the time of initial investment. Equity securities include domestic and foreign common and preferred stock, convertible debt securities, American Depositary Receipts (“ADRs”), Master Limited Partnerships (“MLPs”), real estate investment trusts (“REITs”) and exchange traded funds (“ETFs”), and the Fund may also invest in private placements in these types of securities. To the extent the Fund invests in MLPs, its investments will be restricted to holding interests in limited partners of such investments. To the extent the Fund invests in ETFs, it will do so 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 also invest in debt-securities, including lower-rated debt-securities (“junk bonds”) and foreign securities including depositary receipts.

As the Adviser seeks to reduce the risk of permanent loss of capital, the Adviser follows an investment strategy referred to as “equity income”, emphasizing current income and a conservative stock portfolio. The equity income strategy seeks to generally maintain a portfolio yield that is greater than the S&P 500® Index. Within that context, the balance between current income and prospective growth of dividends is driven by fundamental stock selection.

The Fund may invest up to 25% of its net assets in publicly traded MLPs. MLPs are businesses organized as limited partnerships that trade their proportionate shares of the partnership (units) on a public exchange. MLPs are required to pay out most or all of their earnings in distributions.

With respect to 20% of its assets, the Fund may invest in (1) investment grade and non-investment grade debt securities (i.e., junk bonds), or (2) unrated debt securities determined by the Adviser to be of comparable quality.

The Adviser may sell a stock if the stock has reached a price whereby its risk/reward characteristics are not as favorable, the company’s fundamentals have deteriorated so that the original investment thesis for holding the stock no longer holds or if a better opportunity has been identified.

Principal Investment Risks


Summary Section – Brown Advisory Equity Income Fund

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:

•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 net asset value (“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.

•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.

•Master Limited Partnership Risk. Investing in Master Limited Partnerships (“MLPs”) entails risk related to fluctuations in energy prices, decreases in supply of or demand for energy commodities, unique tax consequences due to the partnership structure and various other risks.


Summary Section – Brown Advisory Equity Income Fund

•Medium Capitalization Company Risk. Securities of medium-sized companies held by the Fund 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.

•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.

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 sustainable domestic companies. The Fund invests primarily in the securities of medium and large capitalization companies that Brown Advisory LLC


Summary Section – Brown Advisory Sustainable Growth Fund

(the “Adviser”) believes (1) have the fundamental strengths (strong financials and business models) to outperform their peers and deliver above-average earnings growth over a market cycle, (2) effectively implement Sustainable Business Advantages (described below), and (3) have attractive valuations.

The investment process starts with fundamentals. 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. In addition, the Adviser views Environmental, Social and Governance (“ESG”) factors as relevant to fundamentals and seeks to understand their impact on companies in which the Fund may invest. The Adviser leverages proprietary ESG research that seeks to understand ESG risk management practices and sustainable opportunities for every security added to the portfolio. However, at the Adviser’s discretion, the Fund is permitted to make an investment without a written ESG assessment on file at the time of purchase, as long as the Adviser believes the security meets the Fund’s sustainability criteria.

As part of assessing sustainable opportunities, the Adviser seeks to identify sustainable companies which are defined as possessing at least one of the following:

(1) Companies whose internal sustainability strategies lead to one or more Sustainable Business Advantages (such as revenue growth, cost improvements, or enhanced franchise value), or that lead to reduced risk to a company’s prospects for growth;

(2) Companies whose products have a competitive advantage as a result of sustainability drivers such as resource efficient design or manufacturing; or

(3) Companies whose products or services offer solutions to long-term sustainability challenges.

Sustainable companies, by their nature, seek to manage risks, not only related to negative environmental and social outcomes, but also ones that might materially impair their financial results. The Fund expects to have low to no exposure to companies that have received international sanctions, derive significant direct revenue from gambling or the production of alcohol, tobacco, weapons, or fossil fuel extraction. However, the Fund may hold companies which the Adviser believes are indirectly or insignificantly exposed to these business activities.

The Adviser pursues active, strategic engagement with companies and other stakeholders in an effort to enhance due diligence and monitor ESG risks and sustainable opportunities that may impact the investment thesis. The Adviser’s ESG research team monitors the companies in the portfolio on an on-going basis, and additional monitoring is also undertaken through a quarterly review of certain ESG characteristics of the Fund.

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

Due diligence on a company’s financial fundamentals and Sustainable Business Advantages is conducted collaboratively among the Fund’s portfolio managers, the Adviser’s ESG research team, and fundamental analysts. Finally, the Adviser uses scenario analyses to assess the company’s valuation and potential for appreciation or downside risk.

In addition to the Adviser’s proprietary and qualitative ESG analysis, the Adviser has access to ESG-related data from third-party providers. The Adviser does not solely rely on third-party data or recommendations when making investment decisions for the Fund. The ESG evaluation process considers risks and opportunities holistically, meaning a security will not necessarily be excluded from investment due to any one particular factor if the overall analysis results in a favorable evaluation by the Adviser. The Adviser is permitted to invest in a security if it determines the security has favorable sustainable opportunities and an acceptable ESG risk profile notwithstanding contrary third party data or third party recommendations. Investing on the basis of ESG criteria is qualitative and subjective by nature, and there can be no assurance that the process utilized by the Fund’s vendors or any judgment exercised by the Adviser will reflect the beliefs or values of any particular investor. The data informing this process is derived from a variety of sources, including the companies themselves and third party sources. The Fund’s vendors provide ESG-related data, research and rating services. The ESG-related data, research and rating services include information related to potentially controversial business exposure, ESG metrics such as emissions and diversity data and controversy reporting. The Adviser believes its process is reasonably designed, although data and qualitative information are inherently subject to interpretation, restatement, delay and omission outside the Adviser’s control.


Summary Section – Brown Advisory Sustainable Growth Fund

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, including both fundamental and ESG factors. Proposals regarding environmental, social and governance issues, in general, are supported, especially when they would have a clear and direct positive financial effect on shareholder value and would not be burdensome or impose unnecessary or excessive costs on the issuer.

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

•The fundamental investment or sustainability 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

investments. Emerging market countries may have policies that restrict investment by foreigners or that prevent foreign investors from withdrawing their money at will.

•Environmental, Social and Governance Policy Risk. The risk that because the Fund’s ESG criteria exclude securities of certain issuers for nonfinancial reasons, the Fund may forgo some market opportunities available to funds that do not use these criteria.

•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 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 investment focus on sustainability factors could cause it to make or avoid investments that could result in the Fund underperforming similar funds that do not have a sustainability focus.

Summary Section – Brown Advisory Mid-Cap Growth Fund

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, 2022, the range was from $271 million to $46.7 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.

Principal Investment Risks


Summary Section – Brown Advisory Mid-Cap 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.

•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.

performance. During the most recent fiscal year, the portfolio turnover rate for the Fund was 27% of the average value of its portfolio.

Principal Investment Strategies

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 20% of its net assets in foreign securities, including in emerging markets.

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.

Principal Investment Risks


Summary Section – Brown Advisory Small-Cap Growth Fund

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.
