Body of the report:

The Management Board of Jastrzębska Spółka Węglowa S.A. [“JSW”, “Company”] hereby reports that it has completed analyses of the key indications that the carrying amount of assets may be impaired, in accordance with the provisions of IAS 36 Impairment of Assets.

Due to the events of 22 January 2025 in the Szczygłowice Section of the Knurów-Szczygłowice mine, where methane ignited and the endangered area had to be sealed off using stoppings, which reduced the assumed production volume, JSW has identified the probability of updating the amount of the recognized impairment losses.

The numerical estimates will be calculated in accordance with the provisions of IAS 36 and the Company will inform about the test results in a separate current report.

The recognition of impairment losses on the assets of KWK Knurów-Szczygłowice will be included in JSW's interim condensed standalone financial statements and in the JSW Group's interim condensed consolidated financial statements for the three-month period ended 31 March 2025.

The update of the impairment losses on the carrying amount will have a non-cash impact on JSW’s and the Group’s operating result [it will not affect the liquidity situation of JSW Group companies].

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.
