MDA SPACE CONTRACTED BY AIRBUS FOR REPEAT ORDER OF ANTENNAS FOR ONEWEB CONSTELLATION EXTENSION

TORONTO, April 20, 2026 /PRNewswire/ - MDA Space Ltd. (TSX: MDA) (NYSE: MDA), a leading provider of advanced technology and services to the rapidly expanding global space industry, has been selected by Airbus to design and build more than 880 Ka-band steerable antennas and 440 Ku-band user replacement antennas for the OneWeb low Earth orbit (LEO) constellation owned by the global operator Eutelsat. This award follows an initial order to supply close to 2,000 antennas to the constellation, the second largest in lower Earth orbit with approximately 650 satellites, given to MDA Space by OneWeb in 2016.

With a heritage of delivering high-quality antenna systems for over 350 satellite missions, MDA Space leverages its expertise in high-volume production and capabilities as a leading supplier of innovative antenna systems to support the deployment of large-scale constellations like OneWeb. MDA Space antennas received a performance award from OneWeb for the original deployment.

"The selection of MDA Space for this repeat order underscores our company's reputation as a reliable partner in enabling advanced satellite communications and connectivity around the world," said Mike Greenley, CEO of MDA Space. "With the growth of satellite constellations continuing to accelerate, MDA Space is ideally positioned to meet full constellation life cycles from the initiation to expansion to the replacement of satellites, antennas and subsystems."

Eutelsat awarded Airbus the contracts to build the OneWeb constellation extension in December 2024 and December 2025, for 100 and 340 satellites respectively. The antennas from MDA Space will be built, assembled and tested at the company's state-of-the-art high-volume satellite production facility in Montréal, and integrated into Arrow telecommunications satellites manufactured by Airbus.
