SEALSQ Approves $10M Investment For 9% Stake In WISeSat To Accelerate Quantum-Ready Satellite Constellation Deployment

SEALSQ Corp (NASDAQ:LAES) ("SEALSQ" or "Company"), a company that focuses on developing and selling Semiconductors, PKI, and Post-Quantum technology hardware and software products, today announced that its Board of Directors has formally approved a $10 million strategic investment in WISeSat.Space AG ("WISeSat"), joining its parent company WISeKey International Holding Ltd (("WISeKey", SIX: WIHN, NASDAQ:WKEY), to accelerate the planned deployment of a secure, quantum-ready satellite constellation.

The $10 million investment secures SEALSQ a 9% equity stake in WISeSat, based on a pre-money valuation of $115 million established through a valuation conducted by an independent expert.

This milestone financing will enable WISeSat to scale up its operations and accelerate the deployment of its planned satellite constellation, as well as provide the flexibility to evaluate opportunities for expanding its access to pre-existing satellite infrastructure through strategic partnerships and investments.

Additionally, WISeSat is finalizing preparations for the launch of WISeSat 3.0 during the last week of June 2025 from California. This post-quantum-ready next-generation satellite, enables quantum-secure communications from space, and has machine-to-machine transactions capabilities powered by SEALCOIN, a collaboration between WISeKey and The Hashgraph Association, using Hedera's decentralized ledger technology (DLT).

WISeSat is also planning to expand its satellite launch operations by partnering with companies such as PLD Space in Spain and SkyRoot Aerospace in India, broadening its global launch footprint and increasing flexibility and resilience for future missions.

This investment underscores SEALSQ's goal to building the world's first quantum-resilient satellite network, designed to deliver ultra-secure communications and transactional IoT (t-IoT) services globally. WISeSat's infrastructure enables SEALSQ to bring post-quantum Root of Trust and secure chips directly to IoT devices, even in the most remote locations. SEALSQ's investment not only accelerates technological advancement but also unlocks a transformational opportunity to secure trillions of IoT devices worldwide.
