Major Indian IT firms, including Infosys, HCLTech, and Happiest Minds, have adjusted their revenue guidance for the current fiscal year due to client delays in decision-making and a slowdown in transformation and discretionary programs. Infosys has revised its FY24 guidance to 1-2.5%, down from the earlier range of 4-7%, reflecting a significant reduction. HCLTech has adjusted its FY24 revenue guidance to 5-6% from 6-8%. Happiest Minds has lowered its growth guidance for FY24 to 12% from 25%. The decision-making slowdown is evident in areas such as telecom, hi-tech, financial services, and retail, impacting the overall industry.
