WISeKey (WKEY) announced the confidential submission of an amended draft registration statement on Form F-4 with the SEC on May 29 by WISeSat.Space, a wholly-owned subsidiary of WISeSat. The draft registration statement relates to the previously announced proposed business combination pursuant to a definitive business combination agreement, dated November 9, 2025, by and among WISeSat, Columbus Acquisition (COLA). Upon completion of the proposed business combination, each of WISeSat and CAC will become subsidiaries of WISeSat.Space, and the combined company is expected to trade on Nasdaq under the ticker symbol (WSAT). WISeSat, a British Virgin Islands business company operating through its wholly owned subsidiary WISeSat.Space AG, is developing secure satellite infrastructure and space-based services designed to support trusted communications, digital identity, secure data exchange and other security-sensitive applications. Carlos Moreira, CEO of WISeSat, said: "This confidential submission is more than a procedural step; it is a critical milestone in WISeSat's intended path to become a Nasdaq-listed space infrastructure company. Strategic autonomy increasingly starts in space, and the next generation of trusted connectivity will require secure satellite infrastructure, post-quantum technologies and digital identity working together from orbit. By leveraging the WISeKey group's expertise in Root of Trust, quantum-resistant semiconductors, authentication and trusted identity, we believe WISeSat is positioned to contribute to a new European model for sovereign, quantum-resilient communications infrastructure. While the proposed transaction remains subject to SEC review, CAC shareholder approval and other closing conditions, this process marks a major step forward in WISeSat's ambition to become a leading European quantum-secure space technology company."
