York Space Systems entered into a definitive agreement to acquire ALL.SPACE. Upon closing of the transaction, ALL.SPACE will operate as a wholly owned subsidiary of York, continuing to serve customers across the broader industry. Founded in 2019 and headquartered in the United Kingdom, with operations in Europe and the United States, ALL.SPACE developed its high-performance, software-defined Hydra Terminal Range to enable simultaneous multi-link, multi-orbit, and multi-band connectivity across LEO, MEO, GEO, and HEO networks. The platform provides resilient, network agnostic communications for platforms on the move, enabling reliable connectivity across space, air, land, and maritime domains. ALL.SPACE's technology is purpose-built to ensure connectivity is maintained in dynamic and contested environments, particularly for mobile platforms operating in unpredictable conditions. ALL.SPACE's smart terminal platform delivers turnkey, on-the-move connectivity, enabling communications to operate across multiple simultaneous pathways, improving resilience by reducing reliance on any single network and maintaining connectivity in contested environments. The consummation of the acquisition of ALL.SPACE is subject to regulatory approvals and customary closing conditions, and is expected to occur in the third quarter. Jefferies LLC served as financial advisor to York, and Sheppard, Mullin, Richter & Hampton LLP served as legal counsel in connection with the transaction.
