WISeKey files registration statement with SEC for proposed redomiciliation to British Virgin Islands
WISeKey International Holding Ltd has filed a registration statement on Form F-4 with the U.S. Securities and Exchange Commission in connection with its proposed redomiciliation from Switzerland to the British Virgin Islands. The filing was made on July 16, 2026 by WISeKey International Corp., a British Virgin Islands company and wholly owned subsidiary of WISeKey, and includes a preliminary prospectus for the merger of WISeKey into that subsidiary, which would then become the publicly traded parent company of the group. The proposed merger remains subject to shareholder approval at an extraordinary general meeting expected on September 9, 2026, as well as SEC effectiveness, Nasdaq and SIX Swiss Exchange listing authorizations, Swiss Takeover Board confirmation, and other conditions. WISeKey shareholders will receive access to the merger agreement, merger report, audit confirmation, and financial statements no later than 30 days before the meeting. The registration statement has not yet become effective and there is no assurance the merger will be completed.
WISeKey International reported preliminary unaudited first-half 2026 revenue of about $11.4 million, a 115% increase year-over-year, and reaffirmed its full-year 2026 revenue growth guidance of 50% to 100%. The company held approximately $495 million in cash and short-term investments with no debt as of June 30. Subsidiary SEALSQ has a commercial pipeline exceeding $225 million through 2029, supported by expected demand for post-quantum cybersecurity products. During the first half, WISeKey filed for WISeSat's planned Nasdaq listing to create a publicly traded quantum computing company valued at about $575 million. Full first-half 2026 financial results are expected in September 2026.

WISeKey’s WISeID poised to benefit from global push for post-quantum digital identity standards
WISeKey International Holding announced that its subsidiary WISeID is positioned to benefit from accelerating government initiatives to adopt post-quantum cryptography, including a reported draft U.S. Executive Order setting timelines for quantum-resistant digital signatures and key establishment. The proposed U.S. framework would require federal agencies to transition key establishment mechanisms to post-quantum standards by 2030 and digital signatures by 2031, reflecting global concern that future quantum computers could compromise current public-key systems. WISeID provides quantum-resilient identity, credential management, and authentication capabilities, and through integration with SEALSQ Corp.’s post-quantum technologies, it is developing next-generation cybersecurity architectures. The company expects increasing demand for quantum-resistant digital identity solutions, secure authentication, and post-quantum certificate management as organizations address harvest now, decrypt later threats.
WISeKey and SEALSQ set up Quantisimo SPV for $575M merger deal
WISeKey International and its subsidiary SEALSQ announced that their jointly established special purpose vehicle, Quantisimo Corp, has entered into a non-binding letter of intent with GigCapital8 to explore a business combination that would create a Nasdaq-listed strategic quantum technology platform. The combined company is expected to have a pre-money enterprise value of approximately $575 million, with plans to increase that valuation to $2 billion through the acquisition of up to five additional quantum companies. The transaction is currently expected to close during the first quarter of 2027. Quantisimo was created to establish a Trusted Quantum Pure-Play platform providing investors with direct exposure to the quantum economy.
WISeKey’s WISeSat.Space invests in FOSSA Systems’ latest financing round
WISeKey International Holding announced that its subsidiary WISeSat.Space has participated in the latest financing round of FOSSA Systems, a Spain-based small-satellite company. The investment builds on a four-year partnership that began in 2021, during which FOSSA contributed to WISeSat’s early satellite missions and helped establish flight heritage across 25 launched low Earth orbit satellites, with 8 currently in operation. WISeSat views the move as reinforcing its European secure satellite infrastructure roadmap, which aims to provide capacity for secure communications, IoT connectivity, and future post-quantum use cases. The investment aligns with WISeKey’s broader ecosystem, including SEALSQ’s post-quantum semiconductor capabilities, though FOSSA is not part of the SEALQUANTUM.COM fund. WISeSat expects the relationship to support next-generation satellite platforms, launch requirements, and ground-segment architecture as it transitions from pilot missions to more advanced orbital infrastructure.

Pubco plans a strategic transformation under the brand SPACEAIQ, while the WISeSat brand will continue for its satellite business. The transaction remains subject to SEC effectiveness, Columbus Acquisition shareholder approval, and other closing conditions.
WISe.ART becomes world's first hardware-authenticated art platform as SEALSQ secures European patent for Back-to-Physical NFT technology
WISeKey's subsidiary WISe.ART has become the world's first hardware-authenticated art platform while its other subsidiary SEALSQ Corp. has been granted a landmark divisional patent by the European Patent Office for its Back-to-Physical NFT technology. The patent covers the method of provisioning NFTs directly into tamper-proof semiconductors, creating an immutable, hardware-rooted link between a digital asset and a physical object. This enables WISe.ART to offer silicon-sealed provenance, ownership history, and authenticity certification that is independently verifiable and secured with post-quantum cryptography. The patent portfolio now spans a Swiss priority filing, the granted European divisional patent, a pending US application, and a further EPO divisional under examination. WISe.ART operates within WISeKey's global trust infrastructure, which secures over 2.6 billion devices, and targets the approximately $65 billion annual global art market.
