Pursuant to Article 226 of the Spanish Securities Market Act, Endesa, S.A. hereby reports the following Privileged Information:

As of December 31, 2021, a re-estimate has been made of the recoverable amount of the assets of the Non-Peninsular Territories (NPT) of the Balearic Islands, Canary Islands, Ceuta and Melilla, taking into account, among others, the expected situation of the “commodity” markets (fuel and carbon dioxide emission right (CO2)) and the costs expected to be recovered for these items in accordance with the planned regulation, as well as the estimated changes in the structure of future generation and their effects on thermal generation. As a result of this re-estimate, there has been an impairment in the Cash Generating Units (CGUs) for each of the Non-Peninsular Territories (NPT) of the Balearic Islands, Canary Islands, Ceuta and Melilla for the total sum of Euro 652 million.

In accordance with the current Dividend Policy of ENDESA, S.A., for the 2021 financial year, the ordinary dividend per share will be equal to 80% of the net ordinary profit attributed to the Parent Company in the Consolidated Annual Accounts, defined as the adjusted Net Income of the Parent Company for the net gain on sales of non-financial assets and net impairment losses on non-financial assets in excess of 10 million euros, as well as the initial net allocation of personnel costs for decarbonisation and digitalisation plans and the net costs of the Public Responsibility Plan for the COVID-19 health crisis. Therefore, the accounting record for the aforementioned impairment has no impact on the determination of shareholder remuneration for the 2021 financial year.
