The Indian firm is a part of London-listed Vedanta Resources Plc, headed by NRI businessman Anil Aggarwal. Asarco is a copper mining, smelting and refining company.
"Sterlite's proposed acquisition is a brilliant strategic move and well-timed as world class resources have become scarce," ABN Amro's co-head of Energy and Resources Kevin Lee said in a statement.
The buyout worth $2.6 billion is the largest Indian outbound M&A deal this year to date and the largest ever purchase of an US asset by an Indian firm, it added.
"The proposed acquisition by Sterlite is a significant and timely step in their international growth plans and we are delighted to be Sterlite's sole advisor. Our enlarged global network within ABN Amro and RBS has helped us offer our client seamless execution across India, UK and the US," MD and Head of Global Banking & Markets for ABN Amro in India Madan Menon said.

Interestingly, ABN Amro was the joint financial advisor to Tata Steel for the nearly $13-billion acquisition of UK-based steel maker Corus. The Tata-Corus deal is India's largest outbound M&A to date.
The buyout by Sterlite includes mainly all of the operating assets of Asarco. "Sterlite is well positioned to benefit from rising copper demand and strong copper prices with the additional operations located in a geopolitically stable market," the statement added.
