Application has been made for admission to trading on the AIM of a total of 3,000,000 new Common Shares of no-par value ("Admission"). Admission is expected on 7 January 2026.

Following Admission, the Company's issued share capital will consist of 513,356,240 Common Shares, with each Common Share carrying the right to one vote. The Company does not hold any Common Shares in treasury.
