Body of the report:

With reference to Current Report No. 32/2025, the Management Board of Enea S.A. ("Company", "Issuer") hereby reports that on 15 September 2025 the Company obtained information about the preliminary outcome of the supplementary capacity market auction for 2026, as announced by Polskie Sieci Elektroenergetyczne S.A., including the capacity auction closing price of PLN 346.37 per kW per year.

In view of the foregoing, the Company estimates that the Enea Group's revenues from the supplementary capacity market auction for the delivery year 2026 may reach approx. PLN 610 million for the contracted capacity of 1,762 MW. In turn, total estimated revenues of the Enea Group for 2026 from the capacity market, taking into account the Group's previously contracted capacity obligations, will reach approximately PLN 1.3 billion.

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.
