Since the beginning of the Strategic Transformation Plan implementation through July 31, 2025, the Company has already identified PLN 1.857 billion in savings, including:

•  the capital expenditure plan was reduced by PLN 1.509 billion,

•  PLN 19 million in savings were achieved in the purchasing area between May 23 and July 31, 2025,

•  Therefore, approximately PLN 328 million of the PLN 360 million savings assumed for 2025 in accordance with the Strategic Transformation Plan were achieved in the purchasing area between January and July 2025.

In addition, the Company reports that it continues to implement a number of initiatives have been launched to improve the utilization of longwall shearers and bring about an increase in coking coal mining volumes. July brought a significant acceleration of work at longwalls and working faces. Incentive measures, which have been introduced on a pilot basis, have already covered 12 longwalls and 15 working faces. Their effectiveness is confirmed by the numbers: the progress of work in the longwalls exceeded TEP targets by 34 percent, and in development by as much as 42 percent. Importantly, all activities are carried out with the highest safety standards. 

The Issuer will report further significant effects of the implementation of optimization initiatives and the Strategic Transformation Plan of JSW S.A. and its subsidiaries in relevant current reports.
