Proposed share sub-division

The board is recommending a 10:1 share sub-division to shareholders for approval at the forthcoming annual general meeting, which, if approved, is planned for implementation on 25 July 2025. This will reduce the nominal value of ordinary shares from 5p to 0.5p and is expected to improve accessibility for a wider range of shareholders. Further details of the proposed share sub-division can be found in the 2025 AGM Circular.
