SmartKem Announces Intent to Acquire Carbonium Core, Expanding into Nuclear‑Grade Graphite

February 02, 2026

SmartKem, Inc. (NASDAQ: SMTK) announced that it has signed a non‑binding letter of intent to acquire 100 % of the outstanding shares of Carbonium Core, Inc., a U.S. company that manufactures nuclear‑grade graphite for advanced reactor technologies. The deal will be financed with $120 million in newly issued Series B Convertible Preferred Stock, which can be converted into common shares at a $1.00 per‑share conversion price after a six‑month period. The transaction is expected to close by February 5 2026, pending customary due diligence and regulatory approvals.

The acquisition represents a deliberate shift in SmartKem’s business model. By adding Carbonium Core’s vertically integrated supply chain—from carbon feedstock to reactor‑qualified graphite—the company gains a domestic, secure source of a critical material that is essential for next‑generation nuclear reactors. The move is intended to diversify revenue streams and leverage SmartKem’s manufacturing scale‑up capabilities to accelerate commercialization of nuclear‑grade graphite, a market that is niche but projected to grow as advanced reactors gain regulatory approval and deployment. The transaction also signals management’s intent to pursue high‑margin, high‑barrier‑to‑entry opportunities that complement its core organic semiconductor technology.

SmartKem’s financial position underscores the urgency of the deal. In the third quarter of 2025 the company reported revenue of only $81 000 and an operating loss of $3.1 million; in the first quarter of 2025 revenue was $23 000 with a similar loss, and the full year 2024 revenue was $82 000 against operating expenses of $11.5 million. Cash and cash equivalents stood at $0.9 million as of September 30 2025 and $1.2 million as of June 30 2025. The company secured $1 million in bridge financing on October 31 2025, but the $120 million preferred‑stock issuance required for the acquisition far exceeds its current cash reserves. The conversion price of $1.00 per share is above SmartKem’s market price of roughly $0.80, indicating that the company is raising capital at a premium to support the transaction and future operations.

Carbonium Core’s financials are not publicly disclosed, but the company’s product—nuclear‑grade graphite—serves a highly regulated and specialized market. The graphite must meet stringent purity and structural requirements for use in advanced reactor cores, and production is subject to federal licensing and environmental oversight. While the lack of disclosed financial data limits a valuation assessment, the $120 million price tag reflects the strategic value of securing a domestic source of a critical material and the potential for long‑term contracts with reactor developers.

The acquisition carries several risks. The transaction is still at the letter‑of‑intent stage, requiring shareholder and regulatory approval, and the company’s limited cash base raises concerns about its ability to fund the deal and sustain operations post‑closing. The preferred‑stock financing will dilute existing shareholders and may affect future capital‑raising flexibility. Additionally, SmartKem has recently terminated a prior letter of intent with Jericho Energy Ventures, indicating a shift in strategic priorities. The company’s pivot into nuclear materials represents a high‑risk, high‑reward move that will test its ability to integrate a new technology platform and navigate a complex regulatory environment.

In summary, SmartKem’s intent to acquire Carbonium Core marks a significant strategic realignment and a bold attempt to enter a high‑barrier, high‑margin market. The deal’s success will hinge on the company’s ability to secure approvals, manage capital constraints, and integrate Carbonium Core’s operations while maintaining its core semiconductor business. The transaction, if completed, could redefine SmartKem’s competitive positioning and open new revenue channels in the emerging nuclear‑materials sector.
