Hindalco Industries, a part of the Aditya Birla Group, will acquire a 100 per cent equity stake in AluChem Companies, a US-based manufacturer of speciality alumina, for an enterprise value of $125 million, it said in a stock exchange filing.
“This acquisition is an important step in our global strategy to build a leadership position in value-added, high-tech materials,” Kumar Mangalam Birla, chairman, Aditya Birla Group, said in a statement. “Our strategic foray into the speciality alumina space will not only accelerate the development of future-ready, sustainable solutions but also open new pathways to pursue high-impact growth opportunities. By integrating advanced technologies into our value chain, we are reinforcing our commitment to self-reliance, import substitution and building scale in innovation-led businesses.”
The acquisition will be carried out through Aditya Holdings LLC, a step-down wholly owned subsidiary of Hindalco Industries. The indicative time period for completion is approximately two to four months, the stock exchange filing stated. Through this deal, Hindalco Industries is expected to gain a strong presence in North America, with an annual capacity of 60,000 tonnes across its three advanced manufacturing facilities in Ohio and Arkansas. Currently, Hindalco operates 500 thousand tonnes of speciality alumina capacity and aims to scale up to 1 million tonnes by FY30, the company said in a statement.
According to the filing, the acquisition will also help the company expand its global footprint in its downstream portfolio of speciality alumina and alumina products.
