WISeKey International Holding (WKEY) announced that its subsidiary, WISeSat.Space Holdings Corp., has submitted an amended confidential Form F-4 draft to the U.S. Securities and Exchange Commission (SEC) on May 29, 2026. This filing is a step towards WISeSat's planned business combination with Columbus Acquisition Corp. (CAC), a SPAC. Upon completion of the transaction, the combined entity is expected to be listed on the Nasdaq stock exchange under the ticker symbol WSAT. The initial Business Combination Agreement was signed on November 9, 2025. WISeSat focuses on secure satellite infrastructure, including trusted communications and digital identity in space, leveraging WISeKey's expertise in cybersecurity and semiconductors. Despite the progress in the listing process, WKEY stock experienced pressure, closing down 6.99% at $8.25 and further slipping to $8.17 in pre-market trading. The deal is still subject to SEC review, approval from CAC shareholders, and Nasdaq listing approval. Maxim Group LLC is acting as the exclusive financial advisor to WISeKey for this business combination.
The advancement of WISeSat's Nasdaq listing plan through an amended SEC filing is a significant regulatory step, but the continued weakness in WISeKey's stock suggests market concerns about execution risks and the overall market reception of the proposed SPAC transaction.
