SEALSQ Corp, a subsidiary of WISeKey International Holding Ltd, has signed a non-binding Memorandum of Understanding with Quobly SAS to negotiate exclusive terms for a potential strategic investment and majority stake acquisition. Under the proposed multi-stage transaction, SEALSQ would inject approximately $200 million in exchange for control of the French quantum computing firm. The deal builds on a November 2025 collaboration and aims to merge SEALSQ’s post-quantum cryptography expertise with Quobly’s silicon-based quantum processor technology. If completed, the acquisition is expected to accelerate development of secure-by-design quantum computing solutions for government and enterprise customers, leveraging SEALSQ’s global partnerships and Quobly’s research capabilities in Grenoble and Paris.

SEALSQ reported preliminary unaudited revenue of $18 million for fiscal year 2025, up 66% year-over-year, with $8 million recorded in Q4 versus $4 million in the same quarter last year. Growth was driven by renewed demand for legacy products and consolidation of five months of revenues from the August 4, 2025 acquisition of IC’ALPS. The Company ended the year with over $425 million in cash and short-term investments, providing robust liquidity for continued R&D in post-quantum semiconductors and software. For FY 2026, SEALSQ reiterates guidance for 50–100% revenue growth, supported by a full year of IC’ALPS revenue, initial sales of the QS7001 product line, further PQC chip launches and the Quantix Edge project. The business development pipeline now exceeds $200 million in potential opportunities through 2028, underscoring rising global demand for quantum-secure technologies.
