Scrip Dividend for 2025/26 Final Dividend

National Grid today announces the scrip dividend reference price for the 2025/26 final dividend. A timetable is provided below.

For ordinary shareholders, the scrip dividend reference price for the 2025/26 final dividend is 1,197.70 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 final dividend is US$80.5453. This is calculated by multiplying the scrip dividend reference price above by five (as there are five ordinary shares underlying each ADR) and by the average US$ 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).

2025/26 Final Dividend timetable:

*The figure shown is gross of a $0.02 per ADR final dividend fee which will be applied to cash distributions made to ADR holders in relation to the 2025/26 final dividend. This fee does not apply to ADRs received through the scrip dividend.
