Please carefully consider the William Blair ETFs’ investment objectives, risks, charges, and expenses before investing. This and other information is contained in the prospectus and summary prospectus, which you may obtain by calling 1-800-742-7272. Read the prospectus and summary prospectus carefully before investing. Investing includes the risk of loss.

The William Blair ETFs are distributed by William Blair & Company, L.L.C., member FINRA/SIPC.

ETF shares are bought and sold on an exchange at market prices rather than NAV and may trade at a premium or discount to NAV. Investors may pay more than NAV when buying shares and receive less than NAV when selling shares. Brokerage commissions and other trading costs may reduce returns. Shares of the ETFs are not redeemable with the ETF other than in creation unit aggregations. There can be no assurance that an active trading market for the ETF's shares will develop or be maintained.

Risks: The Fund’s returns will vary, and you could lose money by investing in the Fund. Equity securities may decline in value due to both real and perceived general market, economic, and industry conditions. Investing in foreign denominated and/or domiciled securities may involve heightened risk due to currency fluctuations, and economic and political risks. Investing in emerging markets can increase these risks, including higher volatility and lower liquidity. Because the Fund may focus its investments in a limited number of securities, its performance may be more volatile than a fund that invests in a greater number of securities. Individual securities may not perform as expected or a strategy used by the Adviser may fail to produce its intended result. Currency rates may fluctuate significantly over short periods of time and may reduce the returns of a portfolio.

Top ten holdings are shown as % of total net assets. Sector and market-cap diversification exclude cash equivalents. Information about the Fund’s holdings should not be considered investment advice. There is no guarantee that the Fund will continue to hold any one particular security or stay invested in any one particular sector. Holdings are subject to change at any time.

The Morgan Stanley Capital International (MSCI) All Country World ex USA Index (net) is a free float-adjusted market capitalization weighted index that is designed to measure large and mid cap equity market performance of developed and emerging markets, excluding the United States. This series approximates the minimum possible dividend reinvestment. The Index is unmanaged, does not incur fees or expenses, and cannot be invested in directly.

30-Day SEC Yield is an annualized yield based on income earned over the most recent 30-day period. Subsidized yields reflect fee waivers in effect. Unsubsidized yields reflect what the yield would have been if no fee waiver had been in effect.

Distribution yield is the sum of a fund’s income distributions period divided by the fund’s net asset value at the end of the period.

Yields are not a guarantee nor necessarily indicative of future performance or income generation, distributions may differ.

Weighted Average Market Capitalization: Market capitalization refers to the total market value of each company’s outstanding shares. The Weighted Average Market Capitalization for a portfolio is calculated as the average market capitalization of the stocks within the portfolio, weighted by the amount of each stock owned. Unweighted Median Market Capitalization: This calculation represents the median market capitalization of the stocks in the portfolio, regardless of the amount of each stock owned. P/E (Price/Earnings) Ratio: This ratio is a measure of valuation. It relates the price of the stock to the earnings per share (EPS) of the company. A stock with a higher P/E ratio would be considered more expensive relative to another stock with a lower P/E. An investor may pay a higher P/E for a stock for several reasons including, but not limited to, an expectation that the company possesses higher returns on invested capital, less economic sensitivity, higher consistency of earnings and/or higher earnings growth potential. EPS (Earnings Per Share) Growth Rate (Projected): This measure represents the weighted average of forecasted growth in earnings expected to be experienced by the stocks within the portfolio over the next 3-5 years. From a portfolio perspective, the portfolio P/E ratio and EPS Growth Rate are weighted averages of the individual holdings’ P/E ratios and EPS Growth Rates. Trailing 1-Year Turnover: This figure reflects the portfolio’s trading activity by calculating the amount of the portfolio’s holdings bought or sold over the prior year, expressed as a percentage of the portfolio’s average market value. Turnover figures may be related to the amount of trading costs experienced by the portfolio. Standard Deviation: A measure of the portfolio’s risk. A higher standard deviation represents a greater dispersion of returns, and thus, a greater amount of risk. Standard deviation returns shown are annualized and calculated using monthly returns. Funds without a 10-year history are reported against the Fund’s inception date. If the Fund’s inception date does not fall on the first day of a given month, the annualized standard deviation is calculated based on the first day of the month following the Fund’s inception date.
