Supplement to the Prospectus and Statement of Additional Information (“SAI”)
for each series listed in 
Appendix A (each a “Fund”)

Dated April 1, 2026

On April 1, 2026 (the “Effective Date”), GSAM Holdings LLC, a subsidiary of The Goldman Sachs Group, Inc. (“Goldman”), completed its acquisition of Innovator Capital Management, LLC (“Innovator”), the investment adviser to the Funds, pursuant to a membership interest purchase agreement (the “Transaction”). As a result of the Transaction, Innovator became an indirect, wholly-owned subsidiary of Goldman.

Under the Investment Company Act of 1940, as amended (the “1940 Act”), the Transaction, which constituted a change in control of Innovator, resulted in the automatic termination of the previous investment management agreement between the Trust and Innovator on behalf of each of the Funds (the “Prior Agreement”) on the Effective Date. In connection with the Transaction, on February 24, 2026, at a joint special meeting of shareholders (together with any adjournments, the “Meeting”), shareholders of certain Funds listed under the caption “Approved Funds” in Appendix A (the “Approved Funds”) approved a new investment management agreement with Innovator (the “New Agreement”) on behalf of each such Fund. For the remaining Approved Funds, Innovator (in its capacity as initial shareholder of the Fund), approved the New Agreement. The New Agreement has also been approved by the Board of Trustees of the Trust (the “Board”) on behalf of each Approved Fund. The New Agreement became effective with respect to each Approved Fund on the Effective Date. The New Agreement is the same as the Prior Agreement, except with respect to the date and term of the agreement and certain other non-material differences.

Solicitation for shareholder approval of the New Agreement with respect to the Funds listed under the caption “Outstanding Funds” in Appendix A (the “Outstanding Funds”) is ongoing. The Trust, on behalf of each Outstanding Fund, has entered into an interim advisory agreement with Innovator in reliance on Rule 15a-4 under the 1940 Act (the “Interim Agreement”), pursuant to which Innovator continues to serve as investment adviser to each Outstanding Fund for up to 150 days following the termination of the Prior Agreement or until shareholders of the Outstanding Fund approves the New Agreement. The Interim Agreement has also been approved by the Board on behalf of each Outstanding Fund and became effective on the Effective Date. The Interim Agreement is the same as the Prior Agreement, except with respect to the date and term of the agreement and certain other differences as required by Rule 15a-4.

Additionally, at the Meeting, shareholders of the Funds also elected fourteen (14) nominees to the Board, whose election became effective on the Effective Date: Cheryl K. Beebe; Dwight L. Bush; Kathryn A. Cassidy; John G. Chou; Joaquin Delgado; Eileen H. Dowling; Lawrence Hughes; John F. Killian; Steven D. Krichmar; Michael Latham; Lawrence W. Stranghoener; Gregory G. Weaver; Brian J. Wildman; and James A. McNamara. Furthermore, on the Effective Date, H. Bruce Bond, Mark Berg, Joe Stowell will no longer serve on the Board.
