BENGALURU (Reuters) -India's Tech Mahindra reported a marginally lower-than-expected first-quarter revenue on Wednesday as clients tightened non-essential spending amid tariff-related uncertainty.

Consolidated sales at India's fifth largest IT services firm by revenue rose 2.7% year-on-year to 133.51 billion rupees ($1.55 billion) in the June quarter.

Analysts, on average, expected 133.83 billion rupees, as per data compiled by LSEG.
