THE IMPACT OF THE ARMED CONFLICT IN UKRAINE ON THE GROUP’S ACTIVITIES

Ukraine's steel sector is facing its most serious crisis since the start of Russia's invasion in 2022, mainly as a result of Russian attacks on Ukrainian steel mills and the blockade of ports. The above events may affect the volume of coke and coal supplied by the Group to the Ukrainian market.

Details of the impact of the armed conflict in Ukraine on the Group's operations are presented in Section 2.3. of the Management Board Report on the activity of Jastrzębska Spółka Węglowa S.A. and the Jastrzębska Spółka Węglowa S.A. Group for the financial year ended 31 December 2025.
