Wisekey Internat SEC Filings

WISeKey International Holding furnished a Form 6-K that includes a press release from its affiliate SEALSQ Corp about deal discussions with Quobly. SEALSQ and Quobly have mutually agreed to stop talks on a potential majority investment or acquisition of Quobly by SEALSQ.

The parties now plan to consider a possible minority investment, to be discussed when Quobly begins its Series A financing round. Although ownership talks have shifted, SEALSQ and Quobly will continue their previously announced technical and industrial collaboration focused on combining secure semiconductor technologies with scalable quantum computing architectures.

SEALSQ Corp, a subsidiary associated with WISeKey International Holding, released preliminary unaudited figures showing strong growth for FY 2025 and an upbeat outlook for 2026. Revenue for 2025 is reported at $18 million, representing 66% year-over-year growth, as the company shifts from a development-focused phase to what it calls a “structured commercial acceleration” phase.

Management highlights more than $425 million in cash and an active business pipeline exceeding $200 million in potential revenue opportunities from 2026 through 2028, including over $60 million tied to QS7001 and QVault TPM programs. For Q1 2026, revenue is expected to exceed $4 million, more than doubling Q1 2025 and benefiting from higher Vault-IC secure element sales and the full-quarter consolidation of IC’ALPS.

For FY 2026, SEALSQ reaffirms guidance for revenue growth of 50% to 100% year-over-year, supported by recurring smart meter and PKI contracts and continued post-quantum product development, including its Quantum Shield QS7001 chip and broader quantum-secure platform investments. All results are preliminary and subject to risks described in SEALSQ’s SEC filings and final 2025 audited financial statements.

WISeKey International Holding Ltd filed a Form 6-K describing the appointment of Gwenael Rouy-Poirier as Chief Financial Officer of its satellite connectivity subsidiary WISeSat.Space Corp, effective February 2, 2026.

WISeSat focuses on secure satellite communications for IoT, defense and critical infrastructure. In November 2025, WISeSat signed a Business Combination Agreement with Columbus Acquisition Corp, a Nasdaq-listed SPAC, to pave the way for a future Nasdaq listing. Rouy-Poirier, a former senior finance leader at GKN Aerospace, Honeywell and Danaher, brings over 25 years of international finance and operational experience, including transformation, restructuring, M&A and capital-markets work across Europe, North America and Asia.

He also serves on the board and audit committee of Coda Octopus Group and advises technology and industrial companies. WISeKey highlights his role in strengthening financial governance, execution discipline and investor readiness as WISeSat scales its satellite-based secure connectivity services globally.

WISeKey International Holding Ltd, through its semiconductor and post-quantum security subsidiary SEALSQ Corp, has entered a non-binding Memorandum of Understanding for exclusive negotiations to make an initial minority investment and potentially acquire a majority stake in French quantum computing firm Quobly SAS. If completed, the contemplated multi-stage transaction would involve a total investment of approximately $200 million by SEALSQ in exchange for a majority interest in Quobly.

The potential deal is framed as part of SEALSQ’s Quantum strategy and is supported in part by its dedicated Quantum Fund, aiming to accelerate sovereign, secure, industrial-scale quantum technologies in Europe. SEALSQ and Quobly plan to expand their existing collaboration to develop secure-by-design, silicon-based quantum computing platforms with embedded quantum-resistant security for sectors such as defense, intelligence, financial services, and pharmaceuticals. The proposed transaction remains subject to definitive agreements, due diligence, corporate and regulatory approvals, and other customary closing conditions.

SEALSQ Corp, a post-quantum semiconductor and cybersecurity company, reported preliminary unaudited key operational and financial metrics for FY 2025. The Company highlighted a strong balance sheet, with cash reserves surpassing $425 million as of December 31, 2025, even after deploying $30 million during the year into strategic investments in WeCan Group, IC’ALPS, Quantix Edge and WISeSat.Space. SEALSQ also cited a business pipeline now exceeding $200 million in potential opportunities from 2026 to 2028 and expects its smart meter and PKI solutions to contribute substantially to 2026 revenue through recurring contracts and expanded deployments. The Company is seeing growing market adoption of its QS7001 post-quantum secure chip, with commercial discussions with up to 115 potential customers and pilots across North America, Europe and Asia Pacific, supporting its positioning as a leader in the emerging quantum-security ecosystem.

WISeKey International Holding AG has signed a business combination agreement to list its space subsidiary WISeSat via a SPAC merger with Columbus Acquisition Corp. A new holding company, WISeSat.Space Holdings Corp (Pubco), will acquire WISeSat.Space Corp. (WISeSat BVI Sub) from WISeKey in exchange for Pubco shares with an aggregate value of $250,000,000 plus any Transaction Financing, with each Pubco ordinary share valued at $10.00.

Columbus Acquisition shareholders will receive one Pubco ordinary share for each CAC ordinary share, after CAC units and rights are separated and converted. Pubco Class F shares will carry 49.9% of total voting power and convert into ordinary shares upon certain transfers. The deal includes covenants to use commercially reasonable efforts to raise at least $10,000,000 of financing, provide up to $900,000 of loans to CAC for expenses, and allows termination if closing has not occurred by July 22, 2026, with reciprocal expense-based termination fees up to $700,000.
