WISeSat Overview 
WISeSat.Space Corp., through its operating subsidiary WISeSat.Space AG, operates a satellite platform designed to provide secure, cost-effective IoT connectivity. The satellites incorporate WISeKey’s post-quantum cryptographic chips from SEALSQ Corp (Nasdaq:LAES) for encryption, authentication, and identity management, including WISeKey’s Root of Trust and WISeID. The constellation supports quantum-resilient communication for sectors including logistics, agriculture, energy, and defense. To date, WISeSat has launched 22 satellites, 14 of which are operational, and aims to deploy 100 satellites by 2030. 

In November 2025, WISeSat will launch a post-quantum-secure satellite equipped with SEALSQ’s Quantum Shield technology aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base, California. The satellite will act as a testbed for developing quantum-resilient satellite communication protocols. 

Management Commentary 
Carlos Moreira, Founder and CEO of WISeKey, stated: 
“This milestone transaction marks a defining moment in WISeKey’s mission to build a secure, sovereign and quantum-resilient satellite infrastructure for the world. By combining WISeSat with Columbus, we are accelerating the commercialization of our satellite-based cybersecurity and IoT ecosystem and enabling WISeSat to emerge as a new, independent publicly listed space-tech company on Nasdaq. Our constellation is purpose-built to deliver trusted IoT connectivity from space, secured by SEALSQ post-quantum cryptographic chips and anchored in the WISeKey Root of Trust. As quantum computing transforms the global cybersecurity landscape, WISeSat is pioneering a future in which critical data, devices, and infrastructures are protected end-to-end, from Earth to orbit. We believe this business combination strengthens our capital base and positions WISeSat to scale from a network of 14 satellites already in orbit to the targeted deployment of 100 further satellites by 2030, reinforcing Europe’s technological sovereignty and leadership in secure space systems. We look forward to continuing this journey as we deploy the world’s first post-quantum-secure satellite platform and shape the foundation of trusted digital communications for the decades ahead.”
