BENGALURU, July 10 (Reuters) - India's Tata Consultancy

Services reported lower-than-expected first-quarter

revenue on Thursday as clients remained cautious about

discretionary spending amid tariff-related uncertainty.

Consolidated sales at India's largest IT services firm by

revenue rose 1.3% year-on-year to 634.37 billion rupees ($7.40

billion) in the June quarter.

Analysts, on average, expected 646.66 billion rupees, as per

data compiled by LSEG.
