Body of the report:

The Management Board of Jastrzębska Spółka Węglowa S.A. [“Issuer,” “Company”] hereby reports that on 25 November 2025 it was notified of the issuance of the Minister of Energy’s decision dated 25 November 2025 repealing the decision of the Minister of Climate and Environment of 11 June 2025 refusing to initiate proceedings to assert an overpayment and refund of windfall tax. 

The decision of the Minister of Climate and Environment was repealed following a review of the Issuer's request for re-examination of the case. The Company announced the repealed decision of the Minister of Climate and Environment and its intention to appeal against it in Current Report No. 55/2025 of 16 June 2025.

The decision of the Minister of Climate and Environment was repealed for formal reasons. The Minister of Energy stated that the Company's request should be examined on its merits by way of a decision and, accordingly, the decision refusing to initiate proceedings was inappropriate.

The decision of the Minister of Energy does not determine whether the Minister of Energy will ultimately refund the windfall tax or refuse to assert an overpayment. The Minister of Energy will evaluate the Issuer's arguments and the request for a refund of the windfall tax and will issue a substantive decision after the administrative proceedings have been completed.

Legal basis: Article 17(1) of Regulation [EU] No. 596/2014 of the European Parliament and of the Council of 16 April 2014 on Market Abuse and Repealing Directive 2003/6/EC of the European Parliament and of the Council and Commission Directives 2003/124/EC, 2003/125/EC and 2004/72/EC.
