Accordingly, JSW notified its business partners of the occurrence of force majeure in accordance with the provisions of the pertinent commercial agreements.

The Company has identified the risk of coal production being down this year by a maximum quantity of 380 thousand tons as a result of the Event compared to the target coal production plan adopted by the Company in JSW’s Strategy incorporating the JSW Group’s Subsidiaries for 2018-2030.
