Q4 FY25 Concall · March 17, 2026 · Institutional Investors Meet
KSB Limited Q4 FY25 Concall Decoded:
Nuclear Pumps Testing Begins. New Segments Finally Start Revenue Printing. And Water/Solar Still Learning To Adult.
KSB’s management just confirmed nuclear testing kicks off March 22. Solar is approaching ₹300 crore. Exports just hit 17% (highest ever). But top-line growth was a modest 7% in Q4 because, you guessed it, nuclear orders got delayed. Again. Story of KSB: exciting tech, frustrating execution timelines.
FY25 Revenue₹2,596 Cr
EBITDA₹387 Cr
EBITDA Margin14.9%
Exports CAGR22%
Nuclear Order Book₹1,300 Cr
01 — Opening Hook
Nuclear Testing Starts March 22. Finally. (Yes, Again.)
Here’s a company that makes pumps for power plants, data centres, refineries, and nuclear reactors. Not exciting? Depends on your definition of excitement. Try funding a ₹280 crore nuclear order, waiting three years for the test bed approval, and then sitting in a management call where the MD casually drops: “Testing starts March 22. I’m personally flying to Tarapur to witness it.”
That’s KSB. Unglamorous. Boring. Absolutely integral to every megawatt of power India generates. And the stock market has basically ignored them while betting the farm on SaaS startups burning cash.
This concall decoded is full of the good stuff: new segments finally converting to real revenue, exports hitting an all-time 17% of sales, aftermarket business becoming a serious profitability lever, and a nuclear order book that could print ₹300–400 crore annually if only India’s project timelines would cooperate. Spoiler: they won’t. Read on—it gets spicy.

Flash Summary: KSB delivered FY25 revenue of ₹2,596 crore (3-year CAGR: 17%), EBITDA of ₹387 crore with 14.9% margin. Q4 was a weird quarter: top-line growth slowed to 7–8% because nuclear orders got postponed, BUT EBITDA margin expanded thanks to high-margin nuclear revenue that did ship (₹30–40 crore worth). Exports hit 17%, highest ever. Solar approaching ₹300 crore. New segments (water, firefighting, mining) growing triple digits but from tiny bases. The real story: nuclear testing finally, finally kicks off March 22. Everything hinges on that.
