Nearly two years after signing a deal to take over Ohio-based aluminium rolled products maker Aleris Corp, billionaire Kumar Mangalam Birla’s Hindalco Industries finally completed the acquisition through its subsidiary Novelis Inc. The enterprise value of the deal, at $2.8 billion, is slightly higher than the initial estimate of $2.58 billion. With the deal closure, Hindalco is now one of the world’s largest aluminium makers.
