As detailed in the Launch Announcement, the Company has received and provided clearance to deal for orders from its employees totalling £79,632, with a further £21,000 proposed to be invested by existing shareholders.

The New Ordinary Shares will, when issued, be credited as fully paid and will rank pari passu in all respects with the existing Ordinary Shares, including the right to receive all dividends or other distributions made, paid or declared in respect of such shares after the date of issue of the new Ordinary Shares.

Canaccord Genuity Limited ("Canaccord Genuity") and Allenby Capital Limited (“Allenby”) acted as joint bookrunners (the "Bookrunners") to the Company in connection with the Placing.

The Acquisition and Fundraising are conditional and subject, among other matters, to shareholders of the Company (“Shareholders”) passing the resolutions required to implement the Acquisition and Fundraising (the “Resolutions”) at a general meeting of the Company which is expected to be held at noon on 2 November 2026 at the offices of the Company, 10 Bonhill Street, London EC2A 4PE (the “General Meeting”), and to the admission of the New Ordinary Shares to trading on AIM (“Admission”).
