ArcelorMittal Kryvyi Rih shuts down one blast furnace, two sintering machines, and its ore processing plant after Ukrainian Railways fails to deliver critical raw materials for over a month. The company warns a full production halt is imminent if supplies are not restored within days. Chief Executive Mauro Longobardo says the firm has operated at a loss for four years and faces compounding pressures from high electricity costs, the European carbon border mechanism, and rising steel imports. The crisis threatens tax revenues and thousands of jobs in the Kryvyi Rih region.
