Ukraine's Largest Steelmaker ArcelorMittal Kryvyi Rih Halts Part of Production After Russian Missile Strike

A Russian missile strike on the night of August 15 to 16, 2026 hit the ArcelorMittal Kryvyi Rih mining and metallurgical complex in central Ukraine, killing two workers, injuring 13 employees and contractors, and forcing the country's largest steel producer to shut down part of its output. The plant was running normally when the missiles landed. The company confirmed that the main power generation units and the blast furnace area took the damage, which is the worst possible combination for an integrated steelworks because both the energy supply and the hot metal chain feed every downstream shop.

ArcelorMittal Kryvyi Rih published its first statement on the morning of Sunday, August 16, describing the site as a civilian mining and metallurgical facility and condemning the strike. One victim was a company employee and the other worked for a contractor. Local authorities reported that one of the bodies was recovered from the rubble during search operations later in the day. The head of the Kryvyi Rih Defence Council said the same wave of attacks also damaged 13 apartment buildings, a medical centre, a school and several shops in the city, and regional officials counted 14 civilians hurt, with 11 taken to hospital and one man in critical condition.

On Monday, August 17, the Luxembourg-based parent group confirmed the partial shutdown and said specialists were still assessing the extent of the destruction along with the feasibility and timing of a restart. No restart date has been given so far, and the company has not said whether the blast furnaces can be restored quickly or whether a longer outage is likely. Until that assessment is published, buyers of Ukrainian long products should treat delivery schedules from Kryvyi Rih as uncertain.

The site sits about 100 kilometres from the front line and employs more than 14,000 people directly, with total headcount above 20,000 including subsidiaries. Its design capacity is over 6 million tonnes of steel, more than 5 million tonnes of rolled products and around 5.5 million tonnes of pig iron per year, but wartime conditions have kept actual output far below that ceiling. In 2025 the plant produced 1.69 million tonnes of crude steel, 2.53 million tonnes of pig iron, 1.56 million tonnes of rolled products and 7.56 million tonnes of iron ore concentrate. Group sales from the Ukrainian operation reached about 1.7 billion dollars last year.

The strike lands on an operation that was already in serious trouble before the missiles arrived. The EU carbon border adjustment mechanism took effect on January 1, 2026 without any exemption or transition period for Ukrainian producers. Importers now face an extra charge of roughly 60 to 90 dollars per tonne, and European customers cancelled their entire first quarter order book, around 300,000 tonnes. The company had planned to ship 1.2 to 1.25 million tonnes to Europe in 2026, close to half of its expected steel output.

That loss triggered a chain of shutdowns through the first half of the year. The blooming mill was suspended, followed by the foundry and mechanical plant, decisions that affected more than 3,000 workers. In May 2026 the group halted part of its mining and steelmaking capacity, including ore extraction, after what it described as systemic failures in flux deliveries by Ukrainian Railways. The railway operator rejected the accusation. By early 2026 the plant was running at roughly half of its capacity overall, with the mining division at about 75 percent and only two blast furnaces in operation. The European Bank for Reconstruction and Development approved a loan of up to 200 million dollars earlier this year to help keep the site alive.

ArcelorMittal has invested more than 1 billion dollars to sustain the Ukrainian operation since the invasion began in 2022, and management has repeatedly said the plant could become a competitive base for its European strategy once the war ends, given the quality of the local iron ore. That calculation is now harder to defend. Senior executives warned in May that closure remained possible because of raw material supply problems and new EU environmental rules, and the company has not answered questions about whether the latest attack changes its commitment to the site.

The consequences reach beyond one company. Ukrainian steelmaking capacity has fallen from 42.5 million tonnes in 2013 to roughly 8 million tonnes in 2026, and Kryvyi Rih is a single-industry city where tax revenue from the plant and its contractors covers up to half of the municipal budget. The plant is also the main domestic source of rebar and wire rod used in reconstruction work and defence-related manufacturing, and it ships iron ore concentrate to other ArcelorMittal units in Europe and to buyers in China. A prolonged outage would push Ukrainian construction buyers toward imports at a time when the country has little foreign currency to spare.

This was not the first strike on the complex. A missile attack in 2022 destroyed the bar rolling mill and killed one employee. The plant has also faced repeated power cuts caused by attacks on the national grid, which forced unplanned stoppages throughout 2025 and 2026. The August strike differs in that it hit the plant's own generating assets directly rather than the grid feeding it, which removes the buffer the site had built to keep its furnaces warm during blackouts.

The wider attack wave that weekend also targeted Kyiv and the Black Sea region with missiles and drones. Romania reported that a Spanish fighter jet on NATO duty shot down a drone that crossed into its airspace, a reminder that the disruption risk is not confined to Ukrainian territory.
