Sterling Green was previously a subsidiary of Shapoorji Pallonji & Company, which held a 56% stake as of March 31, 2024, with the remaining shares owned by chairman Khurshed Daruwala and his family. According to a CareEdge Ratings report, Shapoorji Pallonji's holding fell to 42% by March 31, 2025, after a secondary share sale to a group of investors, resulting in Sterling Green ceasing to be its subsidiary.
The company has seen a sharp improvement in business momentum, driven largely by the rapid expansion of the data centre industry. According to a recent Crisil Ratings report, Sterling Green's order book nearly doubled in FY26, taking its order book-to-revenue ratio to around 3x. The order book stood at about ₹2,900 crore as of May 1, 2026, with nearly 80% of orders from marquee customers including Adani, AirTrunk and DAMAC. Provisional revenue for FY26 rose to ₹1,167 crore from ₹868 crore in FY25, while operating margin remained healthy at 11.5%, compared with 12% a year earlier.
