Exhibit 99.1
press release
ArcelorMittal announces that it is unable to safely and sustainably restart operations at ArcelorMittal Kryvyi Rih following multiple recent missile strikes
25 September, 08:30 CET
Further to the statements issued on 17 August (https://corporate.arcelormittal.com/media/news/regulatory-news/arcelormittal-statement-regarding-missile-strike-on-its-ukraine-plant) and 14 September (https://corporate.arcelormittal.com/media/news/regulatory-news/statement-regarding-missile-strike-on-arcelormittal-kryvyi-rih) following missile strikes on ArcelorMittal Kryvyi Rih, ArcelorMittal (‘the Company’) has with deep regret advised the Government of Ukraine that it is unable to restart operations at its Ukrainian subsidiary in a safe and sustainable manner.
Over the past five weeks, ArcelorMittal Kryvyi Rih has been targeted by four missile strikes, resulting in fatalities, injuries and extensive damage to production facilities. The most recent attack occurred on 21 September. In total the four attacks claimed five lives and injured 17 employees, one of whom remains in a critical condition.
Commenting, Mauro Longobardo, ArcelorMittal Kryvyi Rih CEO, said:
"It is with deep regret that we have concluded that we are no longer able to safely operate ArcelorMittal Kryvyi Rih. Since the war started, our people in Ukraine have worked tirelessly to keep the mines and plant operating. They have been the embodiment of bravery, in circumstances most of us cannot begin to imagine. We are discussing the future of the plant with the Government of Ukraine and will focus on preserving the infrastructure, so when peace finally returns, options for restarting production remain available.”
Since the start of the war in February 2022, ArcelorMittal’s priority has been the safety and economic security of its Ukrainian employees. Employees from across ArcelorMittal rallied to support their Ukrainian colleagues and a range of measures were introduced locally to support employees and their families. The strength and resilience shown by ArcelorMittal Kryvyi Rih’s workforce throughout the conflict has been extraordinary.
ArcelorMittal has also provided financial support to ensure continuity of operations at ArcelorMittal Kryvyi Rih, providing over US$700 million to ArcelorMittal Kryvyi Rih.
ArcelorMittal expects to record a non-cash impairment charge of approximately US$1 billion, principally reflecting the impairment of property, plant and equipment at ArcelorMittal Kryvyi Rih.
