Smartkem Signs Letter of Intent with Carbonium Core, Inc. to Expand Advanced Materials Portfolio into Nuclear-Grade Graphite

MANCHESTER, United Kingdom, Feb. 02, 2026 (GLOBE NEWSWIRE) -- Smartkem, Inc. (NASDAQ:SMTK), ("Smartkem"), a developer of advanced materials, today announced that it has entered into a non-binding letter of intent ("LOI") to acquire 100% of the outstanding shares of Carbonium Core, Inc., a U.S.-based advanced materials company focused on the production of nuclear-grade graphite for advanced reactor technologies.

In connection with this transaction, Smartkem has mutually agreed to terminate its previously announced LOI with Jericho Energy Ventures, with no penalties or disputes arising from the termination. The Company views this transaction as a strategic progression aligned with its long-term materials roadmap.

Under the terms of the LOI, Smartkem intends to acquire all outstanding shares of Carbonium Core, Inc. in exchange for shares of Smartkem Series B Convertible Preferred Stock, subject to the execution of definitive agreements, completion of due diligence, and customary closing conditions. The LOI includes a customary exclusivity period and is non-binding with respect to the consummation of the proposed transaction.

Strategic Fit and Materials Capability Alignment

Carbonium Core, Inc. is a U.S.-based developer of nuclear-grade graphite for advanced reactor systems, focused on converting domestically sourced carbon feedstock into reactor-qualified graphite through fully U.S.-based processing and manufacturing. The proposed transaction combines Smartkem's materials chemistry and manufacturing scale-up capabilities with Carbonium Core, Inc.'s vertically integrated domestic production platform to establish a secure, U.S.-controlled supply chain for a critical nuclear material, reduce reliance on foreign-controlled sources, and directly support national energy security, supply-chain resilience, and advanced nuclear deployment objectives.

Leadership Commentary

"This transaction would expand our materials portfolio into a new and exciting market," said Ian Jenks, Chairman and Chief Executive Officer of Smartkem. "We believe that nuclear-grade graphite is a strategically critical market with significant technical complexity and long-term demand drivers. Carbonium Core, Inc.'s capabilities align strongly with our ambition to build differentiated, high-value materials platforms that address global supply-chain challenges."

"Being one of the first domestic companies to take coal all the way to nuclear-grade graphite is a milestone for Carbonium Core, Inc. and for the U.S. It proves that advanced materials, once thought to be imported necessities, can be engineered domestically with precision, responsibility, and vision," added Suren Ajjarapu, Chief Executive Officer of Carbonium Core, Inc. "Smartkem is a world-class advanced materials company that brings deep expertise and process innovation, and we believe this combination can accelerate our mission to deliver a secure, domestic supply of nuclear-grade graphite for the next generation of U.S. reactor technologies."

Proposed Transaction Highlights

• Expansion into a Critical New End Market: The proposed transaction is intended to expand Smartkem's advanced materials portfolio into nuclear-grade graphite, a strategically critical material required for next-generation nuclear reactor technologies.
  
  
• Alignment with Long-Term Energy and Industrial Trends: Advanced nuclear is expected to play a growing role in energy security and decarbonisation, driving sustained demand for high-performance, reactor-qualified materials with long qualification cycles and high barriers to entry.
  
  
• Strong Technical and Manufacturing Fit: Management believes that Carbonium Core, Inc.'s graphite purification and processing capabilities are highly complementary to Smartkem's expertise in materials engineering, process integration, and manufacturing scale-up.
  
  
• Domestic Supply Chain Opportunity: The combination is intended to support the development of a secure, U.S.-based supply chain for nuclear-grade graphite, reducing reliance on foreign sources for a strategically sensitive material.
  
  
• Portfolio Diversification with Technical Continuity: The proposed transaction represents a logical extension of Smartkem's core competencies into a new market with attractive technical complexity and long-term commercial potential.
