Mumbai-based Tata Consultancy Services Ltd (TCS) won a $2.25 billion contract, the largest ever for an Indian information technology firm, from U.K.-based television ratings measurement company Nielsen. Under this contract, TCS is assured of $320 million in business from Nielsen every year, beginning 2017 through 2020, $186 million in annual revenue from 2021 through 2024 and $139.5 million in 2025, according to a regulatory filing made by Nielsen to the U.S. Securities and Exchange Commission.
TCS will globally provide Nielsen with professional services relating to information technology (including application development and maintenance), business process outsourcing, client service knowledge process outsourcing, management sciences, analytics, and financial planning, reports LiveMint.
“This is a milestone contract given not only the depth of the contract but also the breadth of services,” said Ray Wang, founder and CEO of Constellation Research, a technology advisory firm. “TCS did a good job of managing longer-term costs and gaining some cost efficiencies while renewing a longer contract. There is also upside in the long run as this is more of a strategic partnership than outsourcing contract.“
