    02

    Record Order Book and Strategic Wins

    The company's open order book reached a record high of INR18,618 crores, marking a 2.4x increase from the previous quarter.

A landmark multiyear $1.1 billion deal for AI data centers through FY29, alongside multiple $100 million hyperscaler orders, underpins this robust pipeline and provides strong revenue visibility.
