NOTICE OF ADJOURNMENT OF SPECIAL MEETING

PLEASE VOTE YOUR PROXY TODAY

July 22, 2026

Dear Stockholder:

You recently received proxy materials relating the Special Meeting of Stockholders of Sonoma Pharmaceuticals, Inc. (the “Company”). This important notice is to inform you that the Special Meeting has been adjourned until August 19, 2026 at 2:00 p.m., local time, to allow stockholders additional time to exercise their voting rights by submitting their voting instructions. The adjourned meeting will be held at the Company’s principal executive offices located at 5445 Conestoga Court, Suite 150, Boulder, CO 80301.

This letter was sent to you because you held shares of the Company on the record date and we have not yet received your vote. In order to hold the special meeting, we need to have a quorum for the special meeting (at least a majority of the outstanding shares present and voting at the meeting). Your vote is extremely important, no matter how many shares you hold or how you choose to vote. PLEASE VOTE YOUR SHARES TODAY.

For the reasons set forth in the proxy statement, dated May 5, 2026, the Board of Directors recommends that you vote “FOR” the Company’s reincorporation to the State of Nevada and “FOR” approval of adjournment of the Special Meeting to establish a quorum or to solicit additional proxies in the event that there are not sufficient votes at the time of the Special Meeting. Please vote via the internet or phone as soon as possible or alternatively, please sign, date, and return the enclosed proxy card.

On behalf of your Board of Directors, thank you for your cooperation and continued support.

Sincerely,

/s/ Amy Trombly

Amy Trombly
