ArcelorMittal Shuts Ukraine Steel Plant After Strikes

ArcelorMittal has announced it is shutting production at its Kryvyi Rih steel plant in Ukraine after four strikes over five weeks caused extensive damage and made safe, sustainable operations impossible, the company said. It expects to record a noncash impairment charge of about $1 billion, mainly reflecting a reduced valuation of the Ukrainian unit’s property, plant and equipment. The company said it informed Ukraine’s government of the decision on Friday, September 25. The strikes killed five employees, according to ArcelorMittal; the company also reported that 17 workers were injured, one critically. The reports do not consistently specify the full operational scope of the shutdown, including whether all associated facilities will stop operating. The Kryvyi Rih complex was Ukraine’s largest operational steel plant. It produced 1.7 million metric tons of steel in 2025, according to company figures cited in reports. Its operations also include iron ore mining, which produced 7.6 million tons that year. ArcelorMittal has not provided a restart date.
