TOMI-Carbonium Merger Aims to Onshore Critical Nuclear Graphite Supply — TOMI Environmental Solutions, Inc.

Event summary

TOMI Environmental Solutions (NASDAQ: TOMZ) and Carbonium Core signed a merger agreement on June 29, 2026.
Carbonium is developing technology to produce nuclear-grade graphite from U.S. coal for defense and advanced reactors.
Pilot-scale testing is underway in Oneida, Tennessee, with plans for full-scale commercial production.
The U.S. Department of Energy is monitoring Carbonium’s progress under potential collaboration agreements.

The big picture

The merger positions TOMI to address critical supply chain vulnerabilities in defense and nuclear energy by onshoring production of ultra-high-purity graphite. This aligns with U.S. efforts to reduce reliance on foreign sources amid geopolitical tensions, particularly for materials essential to advanced reactors and military applications. The strategic shift toward domestic manufacturing of these materials underscores growing concerns over supply chain security in the energy transition.

What we're watching

Execution Risk: Whether Carbonium can successfully scale its coal-to-graphite process from pilot to full commercial production.
Regulatory Dynamics: The pace at which U.S. Department of Energy collaboration agreements materialize and shape Carbonium’s operations.
Market Demand: How global electricity demand growth, particularly from AI and data centers, impacts the adoption of advanced nuclear reactors requiring high-purity graphite.
