As previously reported, on November 21, 2025, the Nasdaq Stock Market ("Nasdaq") notified TOMI Environmental Solutions, Inc. (the "Company") that (i) based upon the Company's closing bid price for the preceding 30 consecutive business days, the closing bid price for the Company's common stock, par value $0.01 per share (the "Common Stock") was below the minimum $1.00 per share requirement for continued inclusion on The Nasdaq Capital Market pursuant to Nasdaq Listing Rule 5550(a)(2) (the "Bid Price Requirement") and (ii) the Company was not in compliance with Nasdaq Listing Rule 5550(b)(1), which requires the Company to maintain a minimum of $2,500,000 in stockholders' equity for continued listing on The Nasdaq Capital Market (the "Stockholders' Equity Requirement").

On May 19, 2026, the Company received a letter (the "Letter") from the Listing Qualifications Department (the "Staff") of Nasdaq notifying the Company that because it failed to regain compliance with each of the Bid Price Requirement and Stockholders' Equity Requirement its Common Stock will be delisted from The Nasdaq Capital Market.  The Company plans to file an appeal, which will stay any further delisting action through the hearing and any extension the Hearing may grant.
