Dear Shareholder:

You are cordially invited to attend the 2026 Annual Meeting of Shareholders (“the Annual Meeting”) of Dyadic International, Inc. (“Dyadic”), which will be held on June 18, 2026 at 10 a.m. Eastern Daylight Savings Time. The Annual Meeting will be conducted in virtual format only. You will not be able to attend the Annual Meeting in person. Shareholders can access the Annual Meeting by visiting www.virtualshareholdermeeting.com/DYAI2026.

At the Annual Meeting, you will be asked to consider and vote on the proposals described in the Notice of 2026 Annual Meeting of Shareholders and Proxy Statement, which accompany this letter. We urge you to read these materials carefully. During the Annual Meeting, you will be able to submit questions real-time through the meeting portal.

We hope that you will be able to attend the Annual Meeting, but in any event, we ask that you please vote your shares using the internet or, if you received paper copies of the proxy materials, by calling the toll-free telephone number specified in the proxy card or completing and mailing the proxy card in the postage-paid envelope provided to ensure that your shares will be represented at the Annual Meeting. Instructions on using each of these voting methods are outlined in the Proxy Statement. If you hold shares through a broker or other nominee, you should follow the procedures provided by your broker or nominee.

On behalf of the board of directors, I would like to express our appreciation for your continued support and interest in Dyadic. We look forward to your participation at the Annual Meeting.

Sincerely,
