Represents the first of approximately 90 new antennas to be deployed across approximately 35 ground stations worldwide

Globalstar, Inc. (NASDAQ: GSAT), a next-generation telecommunications infrastructure and technology provider, today announces the successful installation of Clifton-8, the first 6-meter tracking antenna dedicated to its upcoming C-3 mobile satellite system, officially kicking off a sweeping global expansion of Globalstar’s ground infrastructure related to the new Extended MSS Network.

The inaugural installation at the Company’s largest and longest-operating ground station in Clifton, Texas, marks the beginning of a months-long process to install more than 90 new antennas across approximately 35 ground stations in 25 countries and territories. This initiative includes not only major upgrades to existing sites but also the construction of entirely new ground stations, further strengthening the Company’s ability to deliver resilient, high-performance satellite connectivity.

With more than two decades of continuous service, the Clifton station plays a critical role in supporting coverage across the continental U.S., Mexico, and Canada. Clifton-8 is the eighth tracking antenna installed at this site and the first of five new antennas planned to support the C-3 system, representing a significant investment in the functionality, capacity, and future-proofing of Globalstar’s satellite network.

“As Globalstar drives forward with its plans to launch its technologically advanced Extended MSS Network, it is essential that the ground infrastructure to support that system be installed and licensed to operate,” said L. Barbee Ponder, General Counsel & Vice President of Regulatory Affairs. “The installation and operation of Clifton-8 is the first step in a global expansion of our ground infrastructure designed to support our next generation of mobile satellite services to hundreds of millions of people around the world.”
