IMMEDIATE ACTION NEEDED

INNOVATOR ETFS TRUST

Dear Shareholder:

You are receiving this communication as you are a shareholder in one or more of the Innovator ETFs Trust Funds. There continues to be strong vote response regarding the Special Meeting of Shareholders, however, the Special Meeting has been adjourned until March 27, 2026.

While the Fund’s investment strategies and fees will remain unchanged, shareholders are required to approve a new investment advisory agreement for the Funds and to elect fourteen nominees to the Board of Trustees of the Trust. Shareholder approval is needed because Goldman Sachs (through its subsidiary GSAM Holdings LLC) is buying all of Innovator’s ownership interests.

Because the Funds are predominantly owned by retail shareholders like you, we ask that you join your fellow shareholders in voting your shares.

We know the solicitation process has been a tedious and a frustrating process. When you vote your shares, phone calls, emails and paper mailings will stop. You can vote right now by clicking the link below.

Innovator has engaged Sodali & Co. Fund Solutions to solicit Innovator shareholders. If you would like to vote with a live agent you can call Sodali at:

1-866-217-8062

Hours of Operation:

Once you vote, all mailings and calls will stop!

Thank you in advance for your consideration on this important vote.

Regards,

h. bruce bond

President and Principal Executive Officer, Innovator ETFs® Trust
