On May 31, 2023, the Board of Trustees of the Driehaus Mutual Funds approved the re-opening of the Driehaus Micro Cap Growth Fund (the “Fund”) to certain existing investors, as further described below. This change, referred to as a “soft-close,” will be effective immediately after 4:00 pm Eastern Time on June 9, 2023.

·A participant in a qualified retirement plan that offers the Fund as an investment option or that has the same or a related plan sponsor as another qualified retirement plan that offers the Fund as an investment option; or
·A financial advisor or registered investment adviser whose clients have Fund accounts.
You may open a new account in the Fund if you:
·Are an employee of Driehaus Capital Management LLC (the “Adviser”) or its affiliates or a Trustee of Driehaus Mutual Funds;
·Exchange your shares of another Driehaus Mutual Fund for shares of the Fund;

·Are a financial advisor or registered investment adviser whose clients have Fund accounts.
These restrictions apply to investments made directly through Foreside Financial Services LLC, the Fund’s distributor, as well as investments made through intermediaries.

Once an account is closed, additional investments will not be accepted unless you meet the criteria listed above. Investors may be required to demonstrate eligibility to purchase shares of the Fund before an investment is accepted. The Fund reserves the right to (i) eliminate any of the exceptions listed above and impose additional restrictions on purchases of Fund shares; and (ii) make additional exceptions that, in the Adviser’s judgment, do not adversely affect its ability to manage the Fund.
