Results of Oversubscribed Retail Offer

Further to the announcement by the Company in respect of the Retail Offer dated 28 August 2025 (the "Retail Offer Announcement"), Clean Power Hydrogen plc (AIM: CPH2), is pleased to announce that, following the closing of the Retail Offer on the BookBuild platform on 3 September 2025, the Retail Offer was oversubscribed. Accordingly, the Company has elected to increase scale of the Retail Offer to raise total gross proceeds of £0.328 million (the "Retail Offer") through the issue of 6,555,315 Retail Offer Shares at the Issue Price of 5 pence per share. Accordingly, all existing Shareholders who applied in the Retail Offer received 100 per cent of their demand. This total includes the application for 100,000 Retail Offer Shares received from Rick Smith, Non-Executive Director of the Company, which, on issue, will result in Mr Smith having an interest in 258,333 Ordinary Shares, representing 0.05% of the enlarged issued share capital of the Company.

In addition, due to additional demand in the Subscription, the Company has issued an additional 1,000,000 Subscription Shares. Consequently, it is now anticipated that the Company will issue and allot 10,800,000 Placing Shares, 130,233,580 Subscription Shares and 6,555,315 Retail Offer Shares (together, the "New Shares"), resulting in a total of 147,588,895 New Shares to be issued in relation to the Fundraising raising gross proceeds of approximately £7.4 million.

The proceeds will be used as outlined in the Launch Announcement dated 28 August 2025 and will provide additional working capital support and further strengthen the balance sheet.

The Fundraising is conditional on obtaining approval of the Shareholders at a General Meeting of the Company, to be held at the offices of K&L Gates, One New Change, London EC4M 9AF at 11:00 a.m. on 18 September 2025.
