EXHIBIT 99.1

TOMI Environmental Solutions Announces Mutual Termination of Merger Agreement with Carbonium Core

Frederick, MD – September 21, 2026 – TOMI Environmental Solutions, Inc.® (“TOMI”) (NASDAQ: TOMZ), a global leader in disinfection and decontamination solutions, and Carbonium Core, Inc. (“Carbonium”), today announced that they have mutually agreed to terminate their previously announced definitive merger agreement, orginally dated June 28, 2026.

The decision to terminate the agreement was approved by TOMI’s Board of Directors on September 20, 2026. Both parties concluded that proceeding with the business combination is no longer in the best strategic or financial interest of their respective stakeholders.

Pursuant to the Merger Agreement, each party is responsible for its own fees and expenses incurred in connection with the Merger Agreement and the transactions contemplated thereby.

Dr. Halden Shane, CEO of TOMI Environmental Solutions commented, “TOMI has never been in a stronger position. Driven by the global adoption of our SteraMist solution, our business is delivering exceptional high-margin, recurring revenue growth and a healthy pipeline. Walking away cleanly from this transaction is in the best interest of our shareholders as we can now put refreshed focus on driving continued improvement in our operating results while protecting our clean capital structure. With our healthy backlog, the back half of the year should contribute to a strong 2026 for shareholders. In addition, we continue to pursue strategic partnerships with major players in our industry to expand market reach and sales opportunities.”
