Proton Motor Power Systems plc

("Proton Motor" or the "Company")

Update on operations

Proton Motor Power Systems plc (AIM: PPS), the designer, developer and producer of fuel cells and fuel cell electric hybrid systems with a zero-carbon footprint, announces an update on the Company's operations.

Further to the update on the Company's financing provided in its half year report, announced on 18 September 2024, the Company regrets to announce that it has given notice to all its employees based in the Company's Puchheim office of its intention to terminate their employment contracts at the end of the requisite notice period under German law and/or as envisaged by their contracts of employment.

Whilst the directors of Proton Motor continue to seek alternative sources of finance in order to allow the Company to continue to operate beyond 31 December 2024, this action has been necessary in order to allow, should this be necessary, an orderly wind down of the Company's operations by that date. The Company will continue to fulfil outstanding customer orders however, it will not be entering into any new contracts until the financing and future direction of the Company has been resolved.

Further updates will be provided in due course.
