$700 million

Tata Consultancy Services (TCS) will acquire U.S.-based Coastal Cloud for $700 million in an all-cash deal, marking its largest acquisition since going public in 2004. This move enhances TCS's foothold in the fast-growing Salesforce ecosystem, strengthening its presence in the U.S. market. 💼

The acquisition reflects TCS's strategic shift towards larger M&A activities, contrasting its historically conservative approach. Immediate market implications may include increased investor confidence in TCS's growth trajectory.
