On 25 September 2026, ArcelorMittal (MT) said it cannot safely and sustainably restart operations at its Kryvyi Rih subsidiary after missile strikes.
Four strikes over five weeks killed five people and injured 17 employees, one of whom remains in critical condition. The latest strike occurred on 21 September. Production facilities sustained extensive damage. ArcelorMittal has provided more than US$700 million to support continuity of operations at the subsidiary.
The company expects a non-cash impairment charge of approximately US$1 billion, principally for property, plant and equipment at Kryvyi Rih. It is discussing the plant’s future with the Government of Ukraine and intends to preserve its infrastructure so restarting production remains an option when peace returns.
ArcelorMittal (MT) reports that its Ukrainian steel plant, ArcelorMittal Kryvyi Rih, suffered another ballistic missile strike on 14 September 2026, which killed two contractors and injured two employees.
The attack targeted the area of ironmaking complex #1. Specialist teams are assessing damage and the scope of repair work, and the company states it is too early to estimate how long repairs will take. This is the second missile strike on the site in five weeks, following a mid‑August incident that also claimed two lives.
Primary steel production at Kryvyi Rih is currently halted, with other facilities either idled or operating at minimum levels while repairs proceed. The company plans to provide further operational updates once damage assessments are complete.
ArcelorMittal (MT) reported that its Ukraine operation, ArcelorMittal Kryvih Rih, suffered a missile strike over the weekend, injuring 13 employees and contractors and causing two fatalities, one employee and one contractor staff member. The company said all those injured are receiving medical care in city facilities.
At the time of the attack, the plant was operational. The strike damaged main production facilities of the energy and blast furnace units, leading to a partial halt of production processes. Specialists are currently assessing the extent of the damage and the options and timing for restoring operations. ArcelorMittal noted it will provide further updates in due course and highlighted that it generated $61.4 billion of revenue in 2025 with significant global steel and mining operations.
