Analysis · WKEY · Technology
WISeKey's space subsidiary WISeSat.Space has completed its business combination with Columbus Acquisition Corp. and began trading on Nasdaq under ticker SAIQ on October 2, 2026. This transforms WISeSat.Space from a private subsidiary into a separately listed public company, unlocking a new capital-raising channel and establishing an independent market valuation for the space IoT business. The deal was previously announced in August 2026 with SEALSQ committing $10M at ~$10.66/share with price protection down to $5.00. The closing follows CAC shareholder approval on September 30 and comes one day after WISeKey's own redomiciliation to the British Virgin Islands became effective — a coordinated restructuring that splits the parent's space and semiconductor assets into distinct public vehicles.
