Information about approval of G tariff for 2026 for PGE Obrót and necessity to create provision in Supply segment

The Management Board of PGE Polska Grupa Energetyczna S.A. (“PGE”, the “Company”) discloses that on December 17, 2025 the President of the Energy Regulatory Office (the “ERO President”) approved the electricity sale price for G tariff off-takers for year 2026 for PGE Obrót S.A. (PGE’s subsidiary) at an average level of PLN 495.16 per MWh (price excluding value added tax and excise tax).

Due to the lack of full coverage of costs and projected risk of higher – than approved by the ERO – balancing cost and matching the consumption profile, the Company has evaluated the impact of the value of approved tariff on its operations. The Company has identified in the Supply segment a potential loss, as the ERO President did not fully approve incurred costs, that - as at the publication date of this report - is estimated at approx. PLN 560 million.

Lack of full coverage of costs will result in the creation in the consolidated financial statements of the PGE Capital Group for the year 2025 of a provision for onerous contracts (based upon IAS 37 Provisions, Contingent Liabilities and Contingent Assets). Value of the provision will be presented in the periodic report of the PGE Capital Group for the year 2025 which is subject to audit by the Statutory Auditor.
