The Management Fee consists of an Advisory Fee and an Administration and Supervisory Fee paid by the Fund to Baillie Gifford Overseas Limited.

(b)​

Baillie Gifford Overseas Limited has contractually agreed to waive its fees and/or bear Other Expenses of the Fund until April 30, 2027 to the extent that such Fund’s Total Annual Operating Expenses (excluding taxes, sub-accounting expenses and extraordinary expenses) exceed 0.65% for Class K and Institutional Class shares. This contractual agreement may only be terminated by the Board of Trustees of the Trust. Expenses after waiver/reimbursement exceed 0.65% for Institutional Class due to sub-accounting expenses of 0.10%.

Example of Expenses

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. It assumes that you invest $10,000 in the Fund for the time periods indicated, regardless of whether or not you redeem your shares at the end of such periods. It also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. The example below also applies any contractual expense waivers and/or expense reimbursements to the first year of each period listed in the table.

Although your actual costs may be higher or lower, based on these assumptions, your expenses would be:

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These transaction costs, which are not reflected in “Annual Fund Operating Expenses” or in the “Example of Expenses” above, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 18% of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to meet its objective by investing in a portfolio of equities, which include common stock and other equity securities, of issuers located in the U.S.

The portfolio managers seek to identify exceptional growth businesses in the U.S. and to own them for long enough that the advantages of their business models and the strength of their cultures support positive relative performance over the long term.

Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in common stocks and other equity securities of companies whose principal activities are in the U.S. The Fund invests in equity securities either directly or indirectly, such as through depositary receipts, and may invest in preferred stocks, convertible securities, rights and warrants. The Fund typically invests primarily in issuers with a market capitalization of more than $1.5 billion at the time of purchase and may participate in initial public offerings (“IPOs”).

The portfolio managers employ a bottom-up approach to stock selection, seeking to identify companies they believe have attractive long-term growth prospects, and select companies without being constrained by a benchmark. Under normal circumstances, the intended outcome is a portfolio typically consisting of between 30 and 50 growth companies with the potential to outperform the Fund’s benchmarks over the long term. The portfolio managers focus on company research and the long-term outlook of companies and industries. Ideas can come from a wide variety of sources, including, but not limited to, research trips, company meetings, and relationships with industry thought leaders and academic institutions. Stock ideas are normally researched to assess a range of factors, including: long-term growth potential, geographic and industry positioning, competitive advantage, management, financial strength and valuation. The Fund is a non-diversified fund, which means that it may invest a relatively large percentage of its assets in a small number of issuers, industries or sectors The Fund aims to hold securities for long periods (typically at least 5 years), which generally results in relatively low portfolio turnover and is in line

with the portfolio managers’ long-term investment outlook. When assessing a company’s long-term growth prospects, the portfolio managers seek to identify and to incorporate a range of factors that are material to managing the Fund’s investment risks and maximizing capital appreciation. Such factors potentially include the environmental, social, and/or governance characteristics of the company, such as stewardship, sustainable business practices, and/or corporate culture.
