Iridium Communications Inc. has finalized its acquisition of Aireon LLC, securing full ownership of the world’s only space-based Automatic Dependent Surveillance-Broadcast (ADS-B) air traffic surveillance system. The deal, completed 6 July 2026 in McLean, Virginia, integrates Aireon’s oceanic and remote-area coverage with Iridium’s global satellite network and Positioning, Navigation, and Timing (PNT) services. Aireon operates as a wholly owned subsidiary, with CEO Don Thoma continuing in his role under Iridium CEO Matt Desch. The unified platform delivers real-time aircraft visibility, connectivity, and operational data, addressing the aviation sector’s need for comprehensive monitoring beyond ground-based limitations. Aggregate purchase price was approximately $366.7 million, with $183.36 million deferred as a non-interest term loan maturing one year post-closing.
