For ordinary shareholders, the scrip dividend reference price for the 2025/26 interim dividend is 1,130.40 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 2025/26 interim dividend is US$74.2334. This is calculated by multiplying the scrip dividend reference price above by five (as there are five ordinary shares underlying each ADR) and by the average US$ rate for the equivalent dates.

The terms and conditions of the Scrip Dividend Scheme are available on the Investors section of the Company's website and from Equiniti (0800 169 7775).
