They asked not to be identified as no public statements have been made about a potential takeover.Offers of as much as 7 billion rand ($396 million) for AMSA have been discussed, they said. Talks about a takeover by the IDC — the steelmaker’s second-biggest shareholder after billionaire Lakshmi Mittal’s ArcelorMittal — have emerged as the South African authorities try to preserve steel operations crucial to the domestic economy. Since November 2023, AMSA has threatened to shut two loss-making mills that produce grades of steel essential to the automotive and mining industries.Earlier this year, the IDC and South Africa’s Department of Trade, Industry and Competition brokered a deal with AMSA to extend a loan and to consider boosting its 8.2% stake. In return, the DTIC agreed to review AMSA’s complaints about competition from cheap imports, scrap-metal discounts for rivals, high electricity costs and inefficient rail services..Read more:.ArcelorMittal gives update on possible closure of Long Steel Business as deferral deadline looms.“The company has been exploring various strategic options while the IDC has simultaneously been conducting its due diligence into the company and the government has been pursuing structural interventions,” AMSA said in a statement to the stock exchange in Johannesburg on Tuesday. “Significant effort has been given to this exercise, which remains ongoing.”Still, in the absence of a firm commitment, AMSA said it’s switched off the blast furnace at its Newcastle steel mill and has begun talks with employees about the potential closure of its so-called longs business. In total, AMSA’s steel mills in the eastern cities of Newcastle and Vereeniging employ about 3,500 people and support as many as 100,000 jobs at clients and suppliers, according to industry estimates. South Africa’s Department of Employment and Labour said on Tuesday it won’t provide AMSA with any support from its Unemployment Insurance Fund, as such funding is contingent on the company guaranteeing it won’t fire any workers.“It is unfortunate that we have reached this point with AMSA,” it said in a statement. AMSA declined to comment further. “The IDC remains in active and ongoing discussions with relevant stakeholders aimed at identifying sustainable long-term solutions to preserve strategic industrial capacity,” said Tshepo Ramodibe, the institution’s spokesman. He declined to comment further.AMSA isn’t prepared to cover any more losses at the Newcastle mill and neither is the IDC, the people said, meaning that even if the IDC does take over all of AMSA, it may still be mothballed. .Mittal took over the South African steelmaking operations of Iscor Ltd., a state-owned steelmaker and iron-ore miner that had been sold to private investors, in 2003. After Mittal merged his global steel company with Arcelor SA, the South African business was renamed AMSA. The company’s stock has declined 19% this year in Johannesburg to 1.08 rand, giving it a market value of 1.23 billion rand. That compares with a peak of 116 billion rand in 2008. In its most recent financial year, revenue was almost 40 billion rand. To effect a takeover, the IDC — which has provided billions of rands of loans to AMSA — may need to bring in a strategic partner to help run the business, the people said.In addition to Newcastle and Vereeniging, AMSA runs the Vanderbijlpark mill, which produces so-called flat steel used in appliance making and the car industry. It also has a number of idled plants, including one at Saldanha on South Africa’s west coast..© 2025 Bloomberg L.P.
