Q2FY27 Performance Snapshot Management Commentary – Q2FY27 Prayas Goel Prerak Goel Chairman & Managing Director Executive Director Commenting on the results, leadership team of Concord Enviro Systems , said: “Following the supply-chain and logistics disruptions experienced in Q1 FY27, execution improved during the second quarter, enabling us to achieve year-on-year revenue growth. Q2 revenue increased by 7.7% on a YoY basis, while EBITDA grew by 1.6% YoY, supported by stronger domestic execution, and improved operating leverage. The underlying demand environment remains healthy across steel, solar manufacturing, chemicals and pharmaceuticals, while our emerging initiatives, including H-Xtreme, industrial CBG, membrane technologies and Roserve, continue to progress towards commercial scale-up. With a healthy order book and improving execution, we remain focused on converting our India-led opportunity pipeline and gradually normalising international deliveries.” Privileged & Confidential, © 2024, All Rights Reserved.
