KSB Reports Strong FY25 Results Driven by Nuclear Orders

KSB Limited announced strong financial results for the fiscal year ending December 2025, with revenue reaching ₹26,957 million and EBITDA at ₹387 Cr. The company highlighted a significant order book totalling ₹25,848 million, including ₹1,300 Cr specifically from the nuclear sector, underscoring its strategic focus.

Investor Meet Highlights Key Growth Drivers

At an Institutional Investor Meet on March 17, 2026, KSB Limited detailed its performance. Management pointed to the nuclear power sector, a growing solar business, and opportunities in water/wastewater infrastructure as key growth drivers. The company's robust order pipeline positions it to benefit from major industry trends.

Strategic Advantage in Nuclear Sector

KSB Limited is India's only approved supplier of primary coolant pumps for NPCIL's 700 MW Pressurized Heavy Water Reactors (PHWRs), holding substantial orders in this vital area. The company was also the first in India's pump industry to achieve ISO 19443:2018 certification for nuclear safety standards. This deep involvement in India's nuclear energy expansion represents a significant long-term opportunity.

Diversification and Future Expansion

Beyond nuclear, KSB has expanded its solar pump business, securing major contracts through state initiatives. The company is actively developing new business in data centres and green hydrogen, leveraging global expertise. Furthermore, the high-margin mechanical seals segment is set for significant future growth, targeting expansion beyond its current ₹15 Cr revenue.

Order Wins and Targets

In May 2025, KSB secured a significant export order for nuclear pumps from its parent company. More recently, in March 2026, it received its largest single order to date, exceeding €150 million, for reactor coolant pumps for a European nuclear plant. The company targets at least ₹300 Cr in revenue from its solar business in CY2026, supported by increased manufacturing.

Key Financial Metrics

• Revenue: ₹26,957 million (FY2025)
• EBITDA: ₹387 Cr (FY2025)
• Profit Before Tax: ₹322 Cr to ₹352 Cr (FY2025)
• Orders on hand: ₹25,848 million (as of Dec 2025)
• Nuclear order book: ₹1,300 Cr
• Projected solar revenue: ₹300 Cr (by CY2026)

Risks and Challenges

KSB faces potential challenges, including commodity price spikes due to geopolitical events that could impact profit margins. Risks also include delays in project orders or customer uptake, as seen with some postponed nuclear orders. The company faces difficulties in passing on rising domestic project costs because there are no price adjustment clauses in contracts. Supply chain disruptions, particularly in foundries, are being actively managed. Competition is expected to increase in the nuclear segment as NPCIL seeks to diversify its suppliers.

Competitive Landscape

KSB Limited competes with established players like Kirloskar Brothers Ltd. in fluid management solutions and Shakti Pumps (India) Ltd. in the solar pumps segment. Other rivals include WPIL Ltd. and Elgi Equipments Ltd. in related industrial machinery sectors. Kirloskar Brothers reported FY2025 revenue of ₹3,510 crore with 9.07% YoY growth, while Shakti Pumps posted sales of ₹492.35 crore as of March 2026.

Looking Ahead

Investors will track KSB's execution progress on its substantial nuclear order book and the timely testing of NPCIL pumps. Growth in the solar business, especially post-KUSUM 2.0 approvals, and developments in water, wastewater, data centre, and green hydrogen segments will be key. Management's ability to navigate supply chain risks and commodity price fluctuations will also be important.
