Scrip Dividend for 2022/23 Final Dividend

The optional scrip dividend, allowing shareholders to receive new fully paid ordinary shares in the Company, instead of a cash dividend, is available to ordinary shareholders on the register on 2 June 2023, the dividend record date. A timetable is provided below.

For ordinary shareholders, the scrip dividend reference price for the 2022/23 final dividend is 1,059.00 pence.  This is calculated as the average closing mid-market price of an ordinary share for the five dealing days commencing with, and including, the ordinary share ex-dividend date.

For American Depositary Receipt (ADR) holders, the scrip ADR reference price for the 2022/23 final dividend is US$65.9534. This is calculated by multiplying the scrip dividend reference price above by five (as there are five ordinary shares underlying each ADR) and by the average US$ rate for the equivalent dates.  

The current terms and conditions of the scrip dividend scheme are available in the Investors section on the Company'swebsiteand from Equiniti (0800 169 7775).

2022/23finaldividend timetable:
