TOMI Environmental Solutions, Inc. (NASDAQ: TOMZ) entered into a non‑binding letter of intent on April 30, 2026 to merge its wholly‑owned subsidiary with Carbonium Core, Inc., a U.S. company that produces nuclear‑grade graphite for advanced reactor technologies. Under the proposed structure, Carbonium Core would become a wholly‑owned subsidiary of TOMI, and Carbonium Core shareholders would receive TOMI common stock equal to 19.99% of TOMI’s outstanding shares, plus a newly created series of preferred stock that can be converted into TOMI common stock upon shareholder approval.
The LOI values Carbonium Core at approximately $120 million, a figure that contrasts sharply with an independent valuation conducted in November 2025 that placed the company at $990 million. TOMI’s own financial profile is modest: its market capitalization is about $15 million, its revenue for the most recent twelve months was $5.64 million, and it reported an EBITDA loss of $3.58 million, despite a gross margin of 54.6 %. Analysts have rated TOMI’s financial strength at 1 out of 10, underscoring the company’s limited cash reserves and high leverage.
The transaction represents a strategic pivot for TOMI, which has built its core business around the SteraMist® disinfection platform that uses Binary Ionization Technology. Dr. Halden Shane, Chairman and CEO of TOMI, said, "This transaction is intended to position TOMI in a strategically critical advanced‑materials market with long qualification cycles and durable demand drivers tied to next‑generation U.S. nuclear deployment." He added, "Carbonium Core's domestic production capabilities and exclusive purification technology are highly differentiated, and we view this as a meaningful expansion of TOMI's platform alongside our existing SteraMist® franchise." The move is designed to tap the growing demand for U.S.‑controlled supply chains in nuclear reactors and AI data‑center infrastructure, sectors that require resilient, high‑purity graphite.
Carbonium Core has positioned itself as a pioneer in the U.S. graphite supply chain, converting coal from Tennessee into nuclear‑grade graphite through a molten‑salt purification process developed with Oak Ridge National Laboratory. The company had previously entered into a non‑binding letter of intent with Smartkem, Inc. in February 2026, also valuing it at $120 million, before terminating that agreement and pursuing the current deal with TOMI. CEO Suren Ajjarapu noted, "We believe combining with TOMI's Nasdaq‑listed platform will accelerate our ability to deliver a secure, domestic supply of nuclear‑grade graphite for the next generation of U.S. reactor technologies including the energy‑intensive cooling and infrastructure demands of AI data centers." He added, "Carbonium Core is among the first U.S. companies to take coal all the way to nuclear‑grade graphite, a milestone for both the Company and U.S. supply‑chain resilience."
The LOI includes a 45‑day exclusivity period, and the parties expect to negotiate and sign definitive agreements during the second quarter of 2026, with a target completion date of May 30, 2026. The transaction is subject to customary closing conditions, including satisfactory due diligence and shareholder approval. If completed, the combined entity would leverage TOMI’s proprietary Binary Ionization Technology and Carbonium Core’s graphite production to serve a growing demand for resilient, U.S.‑controlled supply chains in advanced energy and data‑center applications.
The deal’s valuation discrepancy—$120 million versus a $990 million independent appraisal—raises questions about the transaction’s pricing and the potential upside for TOMI shareholders. While the LOI reflects a conservative valuation that may be more attainable for a small, high‑growth company, it also suggests that TOMI may be acquiring a company with significant future upside potential. The merger could diversify TOMI’s revenue streams, reduce its reliance on the SteraMist platform, and position it in a high‑barrier, long‑cycle market that aligns with U.S. strategic priorities. However, the transaction carries execution risk, as it depends on due diligence, regulatory approvals, and shareholder consent, and it may strain TOMI’s already modest financial resources.
