ALTERNATIVE PERFORMANCE MEASURES

In addition to the financial information prepared under IFRS, this presentation includes certain alternative performance measures (“APMs”) for the purposes of Commission Delegated Regulation (EU) 2019/979, of March 14, 2019, and as defined in the Guidelines on Alternative Performance Measures issued by the European Securities and Markets Authority on 5 October 2015 (ESMA/2015/1415es). The APMs are performance measures that have been calculated using the financial information from Iberdrola, S.A. and the companies within its group, but that are not defined or detailed in the applicable financial information framework. These APMs are being used to allow for a better understanding of the financial performance of Iberdrola, S.A., but should be considered only as additional information and in no case as a substitute of the financial information prepared under IFRS. Moreover, the way Iberdrola, S.A. defines and calculates these APMs may differ from the way these are calculated by other companies that use similar measures, and therefore they may not be comparable. Finally, please consider that certain of the APMs used in this presentation have not been audited.
