Bengaluru, April 24 (Reuters) - LTIMindtree, India's sixth-largest software company, posted a smaller-than-expected fourth-quarter revenue on Wednesday amid discretionary spending cuts from clients and persisting merger issues at the firm.

Consolidated revenue rose 2.3% to 88.93 billion rupees ($1.07 billion) in the January-March quarter, falling short of analysts' expectation of 89.82 billion rupees, as per LSEG data.

High inflation and geopolitical risks have pushed clients to cut down on discretionary tech spending, with industry body Nasscom estimating that overall revenue growth in the sector more than halved to 3.8% last financial year.

LTIMindtree, formed through the merger of two L&T Group subsidiaries, erstwhile Mindtree and L&T Infotech in 2022, has seen senior leadership exit this year amid merger-related integration risks. The Mumbai-based company's net profit fell 1.2% to 11.01 billion rupees in the fourth quarter. Analysts, on average, expected a profit of 11.58 billion rupees, as per LSEG data. Earlier this month, market leader Tata Consultancy Services posted lower-than-expected revenue, although it said it expected a strong deal pipeline to drive growth this fiscal year, while Infosys, India's No. 2 IT firm, too reported a smaller-than expected revenue.
