Proton Motor Power Systems plc

("Proton Motor" or the "Company")

Last day of dealings on AIM

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 that, further to the announcement on 7 February 2025,  today is the last day of dealings in the Company's ordinary shares on AIM and the Company's ordinary shares will be cancelled from trading on AIM at 7.00 a.m. on 17 February 2025.

Following Cancellation becoming effective, there will be no market facility for dealing in the Ordinary Shares and no price will be publicly quoted for Ordinary Shares as from close of business today. As such, interests in Ordinary Shares are unlikely thereafter to be readily capable of sale and where a buyer is identified, it may be difficult to place a fair value on any such sale. While there can be no guarantee that Shareholders will be able to sell any Ordinary Shares, any Shareholder seeking to do so following the Cancellation should contact the Company in writing by post to the registered office of the Company, addressed to: Proton Motor Power Systems plc, C/O Womble Bond Dickinson (UK) LLP, 4 More London Riverside, London, England SE1 2AU or by email to: [email protected] or alternatively to [email protected]. The Company will then be able to advise as to whether the Directors are aware of any prospective buyers for any Ordinary Shares which the holder thereof wishes to sell at that time.
