This was supported by Civil Infra, Industrial EPC, JJM Water, O&M and International projects. The quarter also marked order book expansion across Industrial Construction, O&M and Civil Infra. From a financial perspective, revenue from operations was INR 1,624 crore, registering a 25.5% YoY increase. EBITDA for the quarter was INR 176 crore (10.8%). The margin was lower compared to Q1 FY 26, primarily due to an increase in royalty costs in the KRBM project following the Government Order on royalty sharing for seized quantities, higher OB removal costs at the KBP mine and increased material costs due to the ongoing middle east conflict. PAT for the quarter was INR 89 crore(5.5%). PAT increased 11% YoY, mainly due to lowerfinance costs and lowertax expenses. The Company secured order inflows of INR 1,864 crore during Q1 FY27. Key awards included the civil and structural works for the 2×800 MW thermal power project at Salboni, West Bengal from JSW Thermal Energy, development of Vande Bharat sleeper trains maintenance depot at Thannisandra, Karnataka as well as O&Mcontracts fromAdani Infrastructure Management Services and MMMOCL. Looking ahead, the management’s priorities remain focused on disciplined execution, improving profitability and executing the order pipeline across core and emerging businesses. With an order backlog of INR 55,398 crore, including MDO, the Company has execution visibility across power, infrastructure, O&M and mining.
