Admission and Total Voting Rights

Applications have been made to the London Stock Exchange for each admission of the New Shares to trading on AIM and it is expected that:

· admission of the Non-EIS/VCT Shares will take place at 8.00 a.m. on 22 September 2025 ("Second Admission").

Following Second Admission, the Company will have 502,013,083 Ordinary Shares in issue with the Company holding no Ordinary Shares in treasury. Therefore, the total number of voting rights will also be 502,013,083.
