Rhea-AI Summary

National Grid plc has issued a pre-close update for the year ended 31 March 2026. Overall performance is described as in line with expectations and consistent with guidance given at the half year.

The company now estimates a net impact of around 1p per share to underlying earnings per share, mainly from customer refund charges linked to a 19 March 2026 FERC judgement on New England Transmission and higher-than-expected US storm costs, partly offset by slightly lower finance costs.

Full year results are scheduled for release on 14 May 2026 at 7am BST / 2am EDT, followed by a presentation and Q&A with CEO Zoë Yujnovich and CFO Andy Agg at 3pm BST / 10am EDT.
