Iridium Completes Acquisition of Aireon

MCLEAN, Va., July 6, 2026 -- Iridium Communications Inc. (Nasdaq: IRDM), a leading provider of global voice, data, and positioning, navigation, and timing (PNT) satellite services, announced today that it has completed its acquisition of Aireon LLC, operator of the world's only space-based Automatic Dependent Surveillance-Broadcast (ADS-B) air traffic surveillance system. 

"Iridium and Aireon are fully aligned in our mission to advance the future of aviation safety. What began as a bold vision more than a decade ago has become a foundational capability for global air traffic management, delivering real-time surveillance and operational intelligence on a truly global scale," said Iridium CEO, Matt Desch. "Together, we will continue investing in the technologies and innovations that we believe will make aviation safer, more efficient, and more resilient for decades to come."

The completion of the acquisition expands Iridium's role in the aviation ecosystem by combining Aireon's space-based air traffic surveillance and aviation intelligence services with Iridium's global satellite communications network and resilient PNT capabilities. Together, these assets create a comprehensive platform for delivering real-time visibility, trusted connectivity and actionable operational data to aviation stakeholders worldwide. As airspace grows more complex and increasingly dependent on resilient infrastructure, Iridium is positioned to provide the critical services that help improve safety, efficiency and operational decision-making on a global scale.

As part of Iridium, Aireon will continue operating as a wholly owned subsidiary focused on delivering industry-leading air traffic surveillance and aviation data services. Don Thoma will continue to serve as Aireon's Chief Executive Officer and will report to Iridium's Chief Executive Officer Matt Desch, ensuring both leadership continuity and close alignment with Iridium's broader strategy.
