Issue of Equity and Admission Total Voting Rights

The EBT Shares will be fully paid and will rank pari passu in all respects with the existing ordinary shares of the Company, including, without limitation, the right to receive all dividends and other distributions declared, made or paid after the date of issue.

Application has been made for the EBT Shares to be admitted to trading on AIM (“Admission”). Admission and settlement of the EBT Shares is expected to take place at 8.00 a.m. on 19 July 2024.

Following Admission, the total number of ordinary shares in issue will be 12,810,728. The Company does not hold any ordinary shares in treasury.
