Tata Technologies CEO Warren Kevin Harris mentioned that the company's Q3 services revenues were impacted by a customer transition in Southeast Asia. The development of two electric vehicles for a customer is nearing completion, resulting in a reduction in headcount. While some impact is expected to continue in Q4, the company remains optimistic for fiscal year 2025 due to deal wins and a strong order book. Operational efficiency and lower sub-contracting contributed to a 140 basis point expansion in EBITDA margin in Q3.
