Programme Originally Announced in February 2026 as Capital Return Mechanism

The share buyback programme under which these purchases were made was first announced on 25 February 2026. Buyback programmes of this type are commonly used by companies to return capital to shareholders and can reduce the total number of shares in circulation over time, thereby adjusting per-share metrics. Investors may be watching for further tranches of purchases under the same programme, as well as any updates to the programme's total authorised size, which the company did not disclose in this announcement.
