The investment closed on October 1, 2026. WISeSat.Space and SEALSQ are subsidiaries of WISeQey Corp. (formerly known as WISeKey International Holding AG, "WISeQey") (Nasdaq/SIX: WQEY), a global quantum cybersecurity and space IoT company.

The PIPE Investment closed on October 1, 2026, concurrently with the closing of the Business Combination.  The purchase price per share, equal to the redemption price, was $10.79 per share.  The Subscription Agreement includes a price-protection mechanism that may result in the issuance of additional WISeSat Ordinary Shares to SEALSQ under certain conditions if the volume-weighted average price of WISeSat Ordinary Shares for the 10 consecutive trading days ending on the 60th calendar day after Closing is below the purchase price, subject to a maximum issuance of an additional 1,073,216 shares. SEALSQ is also subject to customary lock-up restrictions under the Subscription Agreement.

The investment provides WISeSat.Space with additional equity capital as it advances its space cybersecurity strategy, including the planned expansion of its satellite infrastructure, and the integration of post-quantum cryptography (PQC) security technologies into its satellites, ground and user-segment architectures.

WISeSat.Space is engaged in the development of a new generation of WISeSat.Space satellites, intended to support trusted communications, digital identity, and data exchange through space-based infrastructure. The planned architecture is intended to integrate advanced cybersecurity capabilities with satellite communications, creating a foundation for trusted and resilient communications across space and ground infrastructure.

A key focus of the program is expected to be the development of quantum-resilient secure communications capabilities, designed to address emerging cybersecurity threats associated with the future evolution of quantum computing. By incorporating post-quantum security into the satellite communications architecture, WISeSat aims to strengthen device authentication, data integrity, and secure communications across space and ground infrastructure.

The collaboration with SEALSQ is also expected to support the development of a broader trusted space infrastructure, under which WISeSat.Space would provide satellite capacity and related space and ground infrastructure, while SEALSQ would use that capacity to support the development and delivery of planned quantum and post-quantum services using its secure semiconductor, cryptographic and trusted identity technologies.
