It enables us to continue funding the growth and development of our core cybersecurity business and strategic initiatives at each of our subsidiaries. Specifically, WISeSat.Space remains focused on key projects, including the deployment of a low-orbit satellite constellation by 2027 by leveraging cutting-edge technological innovations, and SEALSQ is on track to launch its next-generation post-quantum semiconductors in 2025. Additionally, this financing will support our ongoing work on SEALCOIN, with a second Proof of Concept set for January 2025, which will demonstrate the transfer of tokens via satellite to IoT devices thus accelerating the token's broader availability on digital exchanges in 2025.”
