(1) In the first quarter of 2025 certain immaterial balance sheet amounts related to specific activities undertaken by the business units were reallocated between the operating segments and the Corporate Center. As a result, certain expenses were reallocated, in particular, between Spain, Rest of Business and the Corporate Center. In order to make the period-on-period comparison homogeneous, the figures for the years 2024 and 2023 have been revised, which has not affected the consolidated financial information of the Group.
