TOMI Environmental to merge with nuclear materials firm Carbonium Core

NASDAQ-listed TOMI Environmental Solutions is set to merge with Carbonium Core, ceding roughly 90% of the combined company to Carbonium shareholders.

TOMI Environmental Solutions (NASDAQ: TOMZ), a decontamination and disinfection technology vendor, has signed a definitive merger agreement with Carbonium Core, a US-based development company producing graphite and rare earth metals for advanced nuclear, defence, and critical infrastructure markets. The all-stock transaction would give former Carbonium shareholders approximately 90% of the combined company's common stock once TOMI's own shareholders approve a full conversion of a newly created preferred share class.

The deal is expected to close in the third quarter of 2026, conditional on TOMI completing a minimum $10 million financing, receiving NASDAQ listing approval, and satisfying other standard closing conditions. TOMI noted explicitly that the transaction is intended to help it regain compliance with NASDAQ listing rules, suggesting the company has been operating under a deficiency notice, a detail that adds material context for investors assessing deal rationale.

The deal

Carbonium Core's core asset is a purification technology licensed from Oak Ridge National Laboratory, which the company says supports a vertically integrated production model spanning feedstock sourcing through to shaped nuclear-grade graphite components. That licence is the primary technical differentiator cited in the release; no independent validation of commercial readiness, production throughput, or customer contracts was provided.

Suren Ajjarapu, chairman and chief executive of Carbonium Core, framed the transaction as a response to supply-chain vulnerability: "Nuclear-grade graphite is irreplaceable in the advanced reactors now being deployed to power AI, data centres, and reindustrialisation, yet today it is overwhelmingly sourced abroad." Dr Halden Shane, TOMI's chief executive, positioned the merger as entry into what he described as "one of the most important industrial growth opportunities of the next twenty years." Both quotes carry forward-looking language that should be read alongside the release's own risk disclosures.

Market and regulatory context

The strategic logic is grounded in a genuine structural shift. The US government has signalled sustained support for domestic critical minerals production through the Inflation Reduction Act and Department of Energy loan programmes, and advanced reactor developers, including TerraPower, X-energy, and a number of smaller vendors, require nuclear-grade graphite as a core moderator material. China currently dominates global graphite supply, a dependency that regulators and defence planners have identified as a national security concern.

For a datatech readership, the relevant thread is the power demand side of this equation. Hyperscale data centre operators and AI infrastructure providers have increasingly turned to nuclear power purchase agreements as a source of firm, carbon-free baseload electricity. Several large technology companies have signed offtake arrangements with nuclear operators in the past 18 months, and the deployment pipeline for small modular reactors is partly predicated on that demand signal. A domestic supply chain for nuclear-grade graphite is therefore a second-order dependency for the AI and data centre sectors, even if the connection is indirect.

The transaction also carries US export-control and national security dimensions. Materials used in nuclear reactors fall within the scope of Nuclear Regulatory Commission licensing requirements, Department of Energy oversight, and potentially Committee on Foreign Investment in the United States review for any future international partnerships. Carbonium Core's claim to serve defence contractors alongside commercial reactor developers will likely draw additional regulatory scrutiny as the company moves toward commercial scale.

Investors should note that Carbonium Core describes itself as a development-stage company with no disclosed revenue, and that TOMI's existing disinfection and decontamination business is being substantially diluted by the transaction. The release projects a cross-platform integration, incorporating Carbonium's graphene materials into TOMI's biosafety drones and disinfection robotics, but provides no technical specification or timeline for that work. Key near-term milestones to watch include completion of the $10 million financing, the NASDAQ listing determination, and disclosure of any named reactor-developer or government agency customers.
