WISeSat.Space and SEALSQ Move Forward with Satellite Acquisition Deal

Geneva, Switzerland / New York, United States - October 26, 2026 - WISeSat.Space Holdings Corp. (NASDAQ: SAIQ) has taken a significant step in its commercial development by announcing a binding letter of intent with SEALSQ Corp (NASDAQ: LAES). This agreement will pave the way for SEALSQ to acquire satellite capacity linked to an initial fleet of 12 satellites operated by WISeSat.Space.

Transaction Overview

The proposed arrangement is valued at approximately $15 million and aims to establish foundational satellite and mission control infrastructure for the Quantum Spatial Orbital Cloud (QSOC). This transaction follows SEALSQ’s previous $10 million private investment in WISeSat.Space, enhancing their collaborative efforts.

Enhancing Commercial Infrastructure

In this partnership, WISeSat.Space will oversee the satellite procurement and operational infrastructure, while SEALSQ will focus on developing and commercializing security services integrating with the QSOC. This includes leveraging SEALSQ’s expertise in semiconductor security and cryptographic key management.

The strategic framework aims to monetize satellite capabilities and establish a sovereign trust platform in orbit, aligning with the growing need for secure communications in today’s digital landscape.

Key Features of the QSOC

The initial agreement encompasses 12 satellites, mission control operations, and ground segment support. This ground segment is critical for seamless connectivity, enhancing secure data exchange between satellites and terrestrial systems. The combined technology will enable:

• Post-quantum-secured satellite communications.
• Trusted identity and authentication protocols for connected devices.
• Management of cryptographic keys throughout their lifecycle.
• Access to quantum-generated randomness for enhanced security.
• Secure data exchanges between orbital and ground infrastructures.

Future Expansions and Growth Plans

Carlos Moreira, Chairman and CEO of WISeSat.Space and SEALSQ, emphasized the importance of this agreement for converting their orbital strategies into commercial opportunities. As WISeSat.Space progresses in its Nasdaq listing since October 2, 2026, this initiative marks a crucial foundation for future growth supported by demand for secure services.

Gwenaël Rouy-Poirier, CFO of WISeSat.Space, also shared insights on their long-term objectives. The focus will not only be on launching more satellites but also on creating a scalable business model. This letter of intent lays the groundwork for solid commercial objectives aligned with infrastructural and technological readiness.

Deployment Timeline and Prospects

The timeline for deploying the initial satellite capacity will depend on various factors, including technical qualifications, regulatory approvals, and customer demands. With a goal to eventually deploy up to 100 satellites by 2033, this collaboration between WISeSat.Space and SEALSQ is set to play a pivotal role in global secure communication systems.

Selecting this innovative joint venture illustrates WISeSat.Space's commitment to developing reliable satellite infrastructure that aligns with SEALSQ’s advanced security technologies, ensuring a trusted connection for users across diverse industries.
