County Durham-based Filtronic plc, a designer and manufacturer of products for the aerospace, defence, space and telecoms infrastructure markets, said it has secured its largest order to date with SpaceX.

Filtronic shares rose as much as 6%. The stock has risen more than 100% in the past year.

“Filtronic plc … is pleased to announce the award of a follow-on order from SpaceX for the supply of its market-leading E-band Cerus 32 Solid State Power Amplifier (SSPA),” said the firm.

“The irrevocable order is the largest in value to date, worth $32.5 million (£24.0m), and is expected to be materially fulfilled in FY2026.

“This award reflects the strength and continued success of Filtronic’s Strategic Partnership with SpaceX, the leading Low Earth Orbit technology provider.

“Consequently, the board is now confident the company will exceed current revenue expectations for FY2026.

“Given the cadence of orders the company has received, Filtronic continues to invest in its technology roadmap, across a range of products, given the sizeable market opportunity.”

Filtronic added: “The order has been placed under the framework of the Strategic Partnership, specifically relating to the extension signed in March 2025, and vests all 10,949,079 warrants relating to that agreement, representing 5% of the current share capital of the company.

“As a consequence of this vesting, warrants over 21,805,054 ordinary shares have now vested representing 9.96% of the company’s issued share capital. Warrants over a further 4.96% of the issued share capital remain unvested and subject to meeting certain criteria in relation to new technology.”

Filtronic CEO Nat Edington said: “We are delighted to have secured our largest order to date with SpaceX, reinforcing Filtronic’s growing reputation for delivering high-performance RF solutions to the high-growth space market.

“This milestone builds on the momentum of recent contract awards and highlights the progress we are making as we expand in key strategic markets.”
