WISeKey also notes it has deployed over 1.6 billion microchips across IoT sectors through its cybersecurity and digital identity platform and multiple specialized subsidiaries.
Wisekey International Holding S.A. (WKEY) filed an initial statement of beneficial ownership (Form 3) for Alexander Sebastian Hirsch, who serves as Chief Marketing Officer. The filing does not list any reportable transactions or equity holdings for him at this time.
Wisekey International Holding S.A. (WKEY) reported the appointment of Alexander Hirsch as Group Chief Marketing Officer. He will coordinate global marketing, communications, brand positioning and go-to-market activities across WISeKey and its subsidiaries, including SEALSQ, WISeSat and WISeID, as the Group expands in post-quantum cybersecurity, semiconductors, quantum technologies, satellite communications and digital identity.
Hirsch previously held senior marketing roles at Salesforce, where he led executive marketing across Europe and major global partnership initiatives, and at the World Economic Forum as Head of Marketing Platforms. His mandate includes building a unified global marketing strategy, strengthening the Group’s common narrative, supporting commercial revenue growth, expanding strategic partnerships and enhancing investor-facing communications.
Wisekey International Holding S.A. (WKEY) reports several steps related to the proposed business combination of its space subsidiary with a SPAC. On August 6, 2026, SEALSQ Corp., a subsidiary and Seller alongside Wisekey, signed a Subscription Agreement with the British Virgin Islands holding company that will be the post‑combination parent and with the SPAC counterparty.
Under this agreement, SEALSQ committed to purchase $10,000,000 of that parent’s ordinary shares at a price equal to the SPAC public shareholders’ redemption price. Using an illustrative redemption price of $10.66 per share as of June 30, 2026, this would equal 938,086 ordinary shares, issued concurrently with the business combination closing. The subscription includes price‑protection mechanics that could grant additional shares or pre‑funded warrants if post‑closing trading prices fall below the purchase price, subject to a 9.99% beneficial ownership cap when that feature is elected.
Separately, a First Amendment to the Business Combination Agreement extends the transaction “Outside Date” to October 31, 2026. An earlier Joinder Agreement made SEALSQ a Seller under that Business Combination Agreement, reflecting its ownership of 435 ordinary and 435 Class F shares in the space company being combined.
