ACL - Incident at Vanderbijlpark Works ArcelorMittal South Africa Limited (Incorporated in the Republic of South Africa) (Registration Number 1989/002164/06) Share Code: ACL ISIN: ZAE000134961 (“ArcelorMittal South Africa” or “the company”) INCIDENT AT VANDERBIJLPARK WORKS It is with the deepest regret that ArcelorMittal South Africa advises shareholders of an incident at its Vanderbijlpark operations on Wednesday, 17 February 2021, which resulted in the tragic death of three ArcelorMittal South Africa employees. When the incident occurred, the priority was on securing the safety of all employees and on the search and rescue efforts for the three missing employees. The employees succumbed to injuries sustained when a portion of a 90m stack at one of the operation’s coke batteries failed and fell onto the coke battery control room in which they were working at the time. The company extends its heartfelt condolences and deepest sympathies to the families and colleagues of the deceased. The families of the employees have been informed and are receiving the necessary support from the company. ArcelorMittal South Africa has launched an investigation into the cause of the accident. All relevant authorities have been notified and the company will cooperate fully with thei r investigations. The coke battery affected by the incident is one of five batteries currently in operation at Vanderbijlpark Works. ArcelorMittal South Africa also has additional coke making capacity at its Newcastle Works. The company has been importing limited supply as required and has access to these sources to maintain steel production if needed. Shareholders are further informed that the capacity available at present will ensure sufficient supply of coke for running both blast furnaces at Vanderbijlpark Works and there will therefore be no impact on flat steel production and supply from Vanderbijlpark Works. 18 February 2021 Vanderbijlpark Works For further information please contact: Company Secretary FluidRock Co Sec (Pty) Ltd 016 -889 4077 Tami Didiza: Manager: Corporate Communications Tel: (016) 889 2549 Sponsor to ArcelorMittal South Africa Limited Absa Bank Limited (acting through its Corporate and Investment Banking division) Date: 18-02-2021 05:11:00 Produced by the JSE SENS Department.
