Larsen & Toubro will announce its quarterly and full-year numbers for end-March 2015 on Saturday. Analysts expect L&T to report healthy double-digit earnings growth, backed by revenue traction. Given the strong order book position and consistent order inflow in the past, analysts expect revenue growth of 18-25 per cent year-on-year. While it may maintain its operating profit margin at around 14.5 per cent, PAT may increase about 15-20 per cent.
