Body of the report:

With reference to Current Report No. 41/2025, the Management Board of Enea S.A. ("Company", "Issuer") hereby reports that on 15 December 2025 the Company obtained information about the preliminary outcome of the primary capacity market auction for 2030, as announced by Polskie Sieci Elektroenergetyczne S.A., including the capacity auction closing price of PLN 465.02 per kW per year.

Accordingly, the Company estimates that the Enea Group's revenue from the capacity market may amount to an annual average of approximately PLN 427 million for existing units (with 1-year and multi-year capacity contracts) and the contracted 661 MW. More than 600 contracted MW refers to units No. 5, 7 and 9 in Elektrownia Polaniec, including: units No. 5 and 7 under five-year contracts, and unit No. 9 under a seven-year contract.

In turn, the total estimated revenue of the Enea Group for 2030 from the capacity market, taking into account its previously contracted capacity obligations, will amount to approximately PLN 1,728 million.

These capacity obligations may not be treated as the final outcome of the capacity auction. The final outcome of the capacity auction will be announced by the President of the Energy Regulatory Office in the authority's Public Information Bulletin on the business day immediately following the 21st day after the completion of the capacity auction. Until then, all contracts for the sale of capacity obligations remain conditional.

At the same time, please be advised that if the final outcome of the capacity auction turns out to be significantly different from the preliminary outcome presented above, the Company will provide an update in the form of another current report.
