# TOMI Environmental Solutions (TOMZ) Stock Soars 9% After-Hours: Here's What's Going On

**TOMI Environmental Solutions Inc.** (NASDAQ:TOMZ) shares jumped 9.03% to $1.57 after the bell Monday, following news that the company terminated its merger agreement with Florida-based advanced materials company **Carbonium Core Inc.**

The announcement, made after markets closed Monday, resonated positively with investors as shares surged in late trading.

In the regular session, the stock closed down 1.37% at $1.44, according to Benzinga Pro data.

## **Deal Termination Called Mutual, Strategic**

TOMI Environmental said the merger, originally dated Jun. 28, was terminated by mutual agreement. TOMI’s board approved the decision Sept. 20.

Both companies said the deal no longer served their respective stakeholders’ strategic or financial interests. Under the original agreement, each party will cover its own transaction-related costs.

## **CEO Cites Strong Fundamentals Behind Decision**

Dr. **Halden Shane**, TOMI’s CEO, said, “TOMI has never been in a stronger position.” He pointed to global adoption of the company’s SteraMist disinfection platform, calling it a driver of high-margin, recurring revenue growth and a healthy sales pipeline. 

Shane said walking away from the deal protects TOMI’s “clean capital structure” and lets the company refocus on operating results, with a strong second half expected for 2026. TOMI continues pursuing strategic industry partnerships, he added.
