Update on Comet Litigation

US Court of Appeals reverses judgment and remands for a new trial

XP Power, one of the world's leading developers and manufacturers of critical power control solutions to the Semiconductor Manufacturing Equipment, Healthcare and Industrial Technology sectors, notes and welcomes the judgment issued on 14 July 2026 by the United States Court of Appeals for the Ninth Circuit in the trade secret proceedings brought by Comet Technologies USA, Inc. and affiliates against the Group.

The Court of Appeals has reversed the earlier 2022 judgment of the District Court and remanded the case for a new trial. As a result, the previous award of approximately US$40m in compensatory and punitive damages, together with over US$17m in attorney fees, and the permanent injunction, have been vacated. The cash for these awards is currently held outside the Group in a bond lodged with the District Court.

The Group will continue to defend its position and will provide further updates as appropriate.

The Group will report its interim results on the 4 August 2026 with trading as expected in the first half and ongoing strong order intake.
