Lisbon, October 21^st, 2025: EDP, S.A. ("EDP"), through its 71.3% owned subsidiary EDP Renováveis, S.A.

Following the final investment decision in April 2023, the project has progressed into the final stages of construction. First power was generated in June 2025, and over half of the turbines are now installed and supplying renewable electricity to French households.

Following this transaction, the updated shareholder structure of the îles d'Yeu & Noirmoutier project will be OW (40%), Allianz (20.25%), Sumitomo (29.5%), Banque des Territoires (9.75%) and Vendée Energie (0.5%).

This information is disclosed pursuant to the terms and for the purposes of the article 17 of Regulation (EU) No. 596/2014 of the European Parliament and of the Council.
