ArcelorMittal said it is unable to restart operations at its Ukrainian subsidiary, ArcelorMittal Kryvyi Rih, in a safe and sustainable manner after multiple missile strikes. Four strikes targeted the plant over five weeks, claiming five lives and injuring 17 employees; one remains in critical condition.
The company is discussing the plant’s future with the Government of Ukraine and said it will focus on preserving infrastructure so options to restart production remain available when peace returns. ArcelorMittal has provided over US$700 million to the subsidiary to support continuity of operations. It expects to record a non-cash impairment charge of approximately US$1 billion, principally reflecting impairment of property, plant and equipment at Kryvyi Rih.
ArcelorMittal (MT) reported that its Ukrainian steel operation, ArcelorMittal Kryvyi Rih, suffered a ballistic missile strike targeting ironmaking complex #1. Two contractors were killed and two employees injured, who are receiving medical treatment, and the company is prioritising support for affected families and employees.
Primary steel production at the plant has been halted while repairs are undertaken, with other facilities either idled or running at minimum operating levels. This is the second missile strike on the site in five weeks, and specialists are still assessing damage, so it is too early to estimate how long repairs will take. As broader context, in 2025 ArcelorMittal generated revenues of $61.4 billion and produced 55.6 million metric tonnes of crude steel and 48.8 million tonnes of iron ore across its global operations.
ArcelorMittal reported that its Ukrainian operation, ArcelorMittal Kryvih Rih, was hit by a missile strike over the weekend. The company stated that 13 employees and contractors were injured and two employees died, one directly employed staff member and one contractor employee. Those affected are receiving medical care in city facilities.
The plant was operational at the time, but the strike damaged the main production facilities of the energy and blast furnace production, leading to a partial halt of production processes. Specialists are assessing the extent of the damage and the possibilities and timing of restoring operations, with further updates to follow. In 2025 ArcelorMittal generated $61.4 billion of revenue and produced 55.6 million metric tonnes of crude steel and 48.8 million tonnes of iron ore, underlining the scale of its global operations.
ArcelorMittal reports two key updates. It has published its 2026 half-year report for the six-month period ended 30 June 2026, available on its corporate website and via the Luxembourg Stock Exchange’s electronic database.
The company also announces an expanded collaboration with Microsoft, making Microsoft Azure its primary cloud platform under a Cloud First, Data Centric strategy. Azure, together with services including Microsoft Fabric, Purview and Foundry, will modernize core IT systems, unify data, and support large-scale analytics and AI to enhance cyber security, reliability and operational efficiency across global operations.
ArcelorMittal generated sales of $32.2 billion in the first half of 2026, up from $30.7 billion, as a 10.2% rise in average steel selling prices offset a 4.4% decline in steel shipments to 26.2 million tonnes. Operating income was $1.8 billion versus $2.8 billion, with the prior period boosted by a $1.9 billion bargain purchase gain on the AMNS Calvert acquisition.
Net income attributable to equity holders was $1,258 million, or $1.65 per share, compared with $2,598 million, or $3.40 per share. Mining segment iron ore production increased 19.0% to 19.8 million tonnes, but higher freight, operating costs and depreciation reduced mining operating income. The company recognized a $787 million CO2 emission obligation provision.
Net debt rose to $9.5 billion at June 30, 2026 from $7.9 billion, lifting gearing to 16.7%, reflecting $2.4 billion of capital expenditures, $0.5 billion of share buybacks and $0.3 billion of dividends, partly offset by $952 million of operating cash flow and $663 million of Vallourec share-sale proceeds. Safety indicators improved, with lower lost time injury and recordable injury rates year-on-year, though four fatalities were recorded.
