Due to the lack of full coverage of costs and projected risk of higher -than approved by the ERO - balancing cost and matching the consumptionprofile, the Company has evaluated the impact of the value of approvedtariff on its operations. The Company has identified in the Supplysegment a potential loss, as the ERO President did not fully approveincurred costs, that - as at the publication date of this report - isestimated at approx. PLN 560 million.

Lack of full coverage of costs will result in the creation in theconsolidated financial statements of the PGE Capital Group for the year2025 of a provision for onerous contracts (based upon IAS 37 Provisions,Contingent Liabilities and Contingent Assets). Value of the provisionwill be presented in the periodic report of the PGE Capital Group forthe year 2025 which is subject to audit by the Statutory Auditor.
