The purpose of the programme is to reduce the issued share capital of the Company. All shares repurchased as part of the programme will be cancelled. It is intended that, subject to market conditions, the programme will be completed prior to the Company's first quarter 2026 results announcement, scheduled for May 7, 2026. The company has entered into an arrangement with a single broker, consisting of two irrevocable non-discretionary contracts, to enable the purchase of ordinary shares.
