Overall, the group's performance is in line with our expectations and, as usual, underlying EPS is expected to be weighted to the second half of the year.   The profile of half year operating profit is also expected to be broadly consistent with historical periods:   ●       In UK Electricity Transmission and UK Electricity Distribution, we anticipate operating profit to be broadly evenly split across the year. As a reminder, H1 of FY25 included the contribution from the Electricity System Operator before it was sold on 1 October 2024.   ●       In our US regulated businesses, operating profits are expected to be weighted to the second half. Relative to the same period last year there have been fewer storms in our New York business, as well as new electricity distribution rates in our New England business. As such, we         expect a slightly higher contribution to operating profit from both businesses in the first half relative to the profile last year. ●       In National Grid Ventures we expect a roughly even weighting of profitability across the year.   Our half year results will be announced on Thursday, 6 November 2025.   Enquiries and   contacts                                     Investors and Analysts:   Angela Broad   +44 (0) 7825 351 918   Tom Edwards   Cerys Reece   +44 (0) 7976 962 791   +44 (0) 7860 382 264         Media:   Dan Roberts, Brunswick   +44 (0) 207 404 5959     CAUTIONARY STATEMENT   This announcement contains certain statements that are neither reported financial results nor other historical information.
