SEALSQ Corp, a subsidiary of WISeKey International Holding Ltd, has signed a non-binding Memorandum of Understanding with Quobly SAS to negotiate an initial $200 million investment in exchange for a majority stake in the French quantum computing developer. Under the proposed terms, SEALSQ would first take a minority position before increasing its equity to secure control of Quobly’s silicon-based quantum processor technology. This transaction builds on a collaboration launched in November 2025 and reflects SEALSQ’s commitment to integrating its post-quantum cryptography expertise with Quobly’s hardware, aiming to deliver secure-by-design quantum computing solutions for enterprise and government clients.

Preliminary unaudited data show that SEALSQ’s 2025 revenue rose by 66% year-on-year to $18 million, driven by $8 million in fourth-quarter sales versus $4 million in the prior period. Growth stemmed from renewed demand for legacy products and five months of contribution from IC’ALPS, acquired on August 4, 2025. The company’s cash position exceeded $425 million at December 31, 2025, providing ample funding for R&D and strategic deals. Despite revenue headwinds from the shift to next-generation post-quantum semiconductors and software, management expects 2026 revenue to climb 50% to 100%, supported by full-year IC’ALPS integration, the QS7001 product launch, additional PQC chip roll-outs and initial Quantix Edge revenues.

SEALSQ’s business pipeline now exceeds $200 million in potential opportunities through 2028, including over $60 million from QS7001 and Qvault TPM offerings. The company has secured more than a dozen initial customer discussions spanning North America, Europe and Asia Pacific, and entered supply agreements for over 24 million smart meters as part of the UK’s implementation program. Additional PKI contracts with major utilities and smart-home providers such as Hager and Delta Dore are expected to generate multi-year subscription revenues. Collaborations with system integrators and standards bodies aim to accelerate adoption of SEALSQ’s quantum-resistant products worldwide, positioning the company to capture surging demand for sovereign, quantum-secure infrastructure.
