The Company's issued capital as at 30 June 2026 consisted of 2,432,397,125* Ordinary Shares of 28 101/108 pence each ("Ordinary Shares"), with voting rights. 205,812,357 Ordinary Shares were held in Treasury, in respect of which, voting rights were not exercised.

\* The Company has recently identified 28,355 Ordinary Shares, representing approximately 0.002% of its issued share capital, purported to have been issued by the Company to certain of its subsidiaries in 1997 as part of the merger between Guinness PLC and Grand Metropolitan plc. Since subsidiaries cannot generally hold shares in their parent, the Company has determined that such issues were null and void. Consequently, the Company's share register is being rectified and the record of its issued share capital held by the registrar of companies is being updated accordingly.
