The Board of Directors of Oswal Pumps Limited at its meeting held on 8th August 2026 took on record the unaudited Financial Results for the first quarter of Financial Year 2026-27. ₹ Mn Financial Summary Q1 FY27 Q1 FY26 YoY% Q4 FY26 QoQ% FY26 Total Income 4,817 5,150 (6.5%) 5,167 (6.8%) 20,859 EBITDA 825 1,419 (41.9%) 1,250 (34.0%) 5,354 EBITDA Margin 17.1% 27.5% (1,042 bps) 24.2% (708 bps) 25.7% PAT* 538 947 (43.1%) 925 (41.8%) 3,763 PAT Margin 11.2% 18.4% (721 bps) 17.9% (673 bps) 18.0% Diluted EPS (in ₹) 4.86 8.54 (43.1%) 8.53 (43.0%) 34.73 *Profit for the period attributable to the owners of the parent Commenting on the results, Mr. Vivek Gupta, Chairman and Managing Director, Oswal Pumps Limited, said: “The Company commenced FY27 with continued execution of its order book, even as the tender pricing environment across the industry turned more competitive. Total Income for the quarter stood at ₹4,817 million. EBITDA was ₹825 million, translating into a margin of 17.1%, while PAT stood at ₹538 million with a PAT margin of 11.2%. The decline in margins during the quarter was primarily attributable to industry-wide competitive bidding under the Magel Tyala scheme, which resulted in a 9% reduction in realisations. This impact was partially mitigated by the Company's focused cost and value-engineering initiatives, resulting in a net 548 bps QoQ decline in gross margin. EBITDA margin correspondingly declined by 708 bps QoQ, on account of the fall in gross margins, an increase in employee benefit expenses driven by annual increments and hiring at senior level, and the impact of negative operating leverage. The Company's pump order book stands at 22,025 pumps as of date, with a near-term pipeline of 12,500 pumps across direct PM KUSUM, Magel Tyala, indirect PM KUSUM, and export orders. Given the delay in the rollout of PM KUSUM 2.0, the Company continues to focus on diversifying beyond its core government-led solar irrigation business. As part of this strategy, the Company is also evaluating entry into the Jal Jeevan Mission, where it has identified an addressable pipeline of approximately 42,000 pumps. Alongside this, the Company continues to scale its presence across Rooftop Solar, Utility and Commercial & Industrial (C&I) Solar EPC segments. As on date, the order book across these businesses stands at approximately 72 MW, backed by a wider pipeline of 359 MW, underscoring the strength of the Company's expanding addressable market beyond its core government-led solar irrigation business. Backed by a healthy execution pipeline, a rapidly growing presence across multiple renewable energy segments and proven project execution capabilities, the Company remains focused on disciplined execution, operational efficiency and creating long-term value for all stakeholders."
