Iridium buys full control of Aireon to deepen space-based air traffic surveillance

Iridium Communications has closed its acquisition of Aireon, securing full ownership of the space-based air traffic surveillance company that operates the world’s only global ADS-B system. Iridium already held a 39% stake and moved in May 2026 to buy the remaining 61% from a consortium of air navigation service providers, including NAV CANADA, ENAV, the Irish Aviation Authority, Naviair Satellite and NATS. The definitive agreement valued the remaining stake at approximately $366.7 million in purchase price, with Iridium also assuming about $155 million of Aireon’s outstanding debt, bringing the total transaction value to roughly $520 million for the 61% interest. Half of the cash consideration is being paid at closing and the other half on the one-year anniversary, funded in part by a seller-provided $183.36 million, one-year, interest-free term loan secured by a first-priority lien on Aireon’s equity.

The deal makes Aireon a wholly owned subsidiary of Iridium, with Aireon continuing to focus on air traffic surveillance and aviation data services while leveraging Iridium’s global satellite communications and positioning, navigation and timing capabilities. Don Thoma will remain CEO of Aireon and report to Iridium CEO Matt Desch, preserving management continuity as the businesses integrate. Iridium positions the acquisition as a way to expand its role in the aviation ecosystem by combining Aireon’s space-based surveillance and aviation intelligence platform with Iridium’s communications network to deliver real-time aircraft visibility, trusted connectivity and operational data to aviation stakeholders worldwide. According to transaction disclosures, Aireon’s revenue has grown at a 10% CAGR over the past three years, and Iridium expects at least $100 million in additional annualized service revenue and $30 million of OEBITDA from the consolidation. The strengthened aviation portfolio also comes as Iridium itself is set to be acquired by Rocket Lab in a separate $8 billion cash-and-stock transaction, positioning the combined Iridium–Aireon assets within a broader end-to-end space services strategy.
