Subject: Update on impairment test results

Legal basis: Article 17(1) of MAR – inside information

With reference to Current Report No. 10/2026 of 11 March 2026 regarding the results of impairment tests of non-current assets of the Energa Group (the “Group”) conducted as at 31 December 2025 in accordance with IAS 36, the Management Board of Energa S.A. hereby announces that on 27 March 2026 it obtained information on the need to change the method of calculating impairment charges for the above-mentioned assets, which affects the amount of the charges by a total of approximately PLN 0.25 billion.

The above change concerns renewable energy assets (RES) in the electricity generation segment. The need for this change was identified during the preparation of the consolidated financial statements for 2025, as part of the audit of these statements. As a result of the analyses, the impairment charge indicated in Current Report No. 10/2026 was reduced by PLN 25 million. Furthermore, as a result of the conducted analysis, the Company reversed an impairment allowance in the amount of PLN 220 million due to the business reorganization in Energa Wytwarzanie and the recognition of a new cash-generating unit (CGU) in the form of a virtual power plant comprising hydro, wind, and photovoltaic assets.

As a result, the currently estimated total amount of impairment charges for the Energa Group’s non-current assets is approximately PLN 120 million, with a reversal of impairment charges amounting to PLN 220 million.

The change in the impairment charges is non-cash in nature and does not affect the Company’s current cash flows. The final results of the impairment tests and the value of impairment charges will be presented in the consolidated financial statements of the Energa Group for 2025.
