Mar 2026 quarter: operating margin 8%, profit -22.9% on a year earlier, geopolitical cost pressures and mix shift toward lower-margin government orders; operating profit guidance of 13-14% appears under stress in latest quarter.

The main risks

• Q1 CY2026 Margin Compression, operating margin at 8% vs 13-14% Guided Range: Mar 2026 quarter: operating margin 8%, profit -22.9% on a year earlier, geopolitical cost pressures and mix shift toward lower-margin government orders; operating profit guidance of 13-14% appears under stress in latest quarter. ✓ fact
• Nuclear Delivery Timeline Risk, NPCIL Process Outside KSB Control: First 11 Kudankulam pumps dispatched in Q1 2026 but full nuclear backlog execution depends on NPCIL testing and acceptance, additional slippage risk remains. ✓ fact
• Revenue Growth Deceleration, 6.4% CY2025 vs Historical 15-17%: Historical revenue yearly growth 15-17% collapsed to 6.4% in CY2025, management attributes entirely to nuclear timing; if conventional business also slows, thesis breaks. ✓ fact

When KSB reports July to September 2026, these are the 5 checks that show whether the story is still on course. First: Q2 CY2026 (Jun 2026) revenue, must show nuclear contribution driving >12% on a year earlier growth.

KSB is on one of our India lists: 52 week high & low.

KSB Ltd earned ₹57.0 Cr of net profit in the Jun 2026 quarter, −18.6% on the same quarter a year earlier. Full-year FY25 profit was ₹270 Cr. Over 10 years profit has grown 14.6% a year on average. That is 8.2% of the quarter's revenue. The same quarter a year earlier earned ₹70.0 Cr.

Net profit is what is left after every cost, interest and tax. Earnings per share, dividends and book value all grow from it.

For the full year, FY25 profit was ₹270 Cr (+9.3% on the year before).

Why profit moved: revenue changed +3.6% on a year earlier and the margin moved −2.0 percentage points. Sales did the work while the margin got thinner.

On average over the last four quarters, profit changed −5.3% and revenue +4.5%. Profit is growing slower than sales: rising costs are taking part of the growth.

KSB Ltd reported ₹691 Cr of revenue in the Jun 2026 quarter, +3.6% on the same quarter a year earlier. That is the 12th quarter in a row with growth on the year before. Over 10 years it has grown 12.7% a year on average. The last full year, FY25, came in at ₹2,696 Cr.

Revenue is everything the company billed its customers in the period.

Why this happened. KSB is the only Indian company qualified for NPCIL nuclear pump supply. The Gorakhpur (Haryana) and Kudankulam projects together represent Rs 1,281.6 crore of orders on hand as of Dec 2025. After a full year of dispatch delays caused by NPCIL testbed electrical/auxiliary issues, Q1 CY2026 saw first delivery: 11 pumps to Kudankulam. Nuclear pumps carry materially higher EBITDA margins than conventional business. MD Rajeev Jain confirmed in Nov 2025 concall that revenue slowdown vs 15-17% historical CAGR was 'mainly attributable to the delay in dispatching nuclear pumps.' As dispatches accelerate through CY2026, this unlocks a non-linear earnings step-up. An additional fleet tender from NPCIL…

The last four reported quarters add to ₹2,726 Cr.

FY25 revenue was ₹2,696 Cr, +6.4% on the year before.

Recent pace: the last four quarters grew +4.5% on average, against 12.7% a year over the longer run, so this year is growing slower than its own long-run rate.

Is growth speeding up? Revenue over the last 12 months grew +4.7%, against +7.5% a year over the last 8 quarters (stabilising); profit over the last 12 months grew −4.3%, against +6.2% a year (rolling over).

KSB Ltd's operating margin was 12.0% in the Jun 2026 quarter, 2.0 percentage points lower than the same quarter a year ago. Its latest full-year margin is the highest it has ever reported. Across 12 years it has been between 11.0% and 14.0%. The latest quarter is within that range.

Operating margin is what is left from every ₹100 of sales after the costs of running the business, before interest and tax. It shows pricing power and cost control.

Why this happened. SupremeServ was formalized as a brand in 2018, with the Chinchwad plant dedicated to aftermarket operations post the Shirwal Energy Pumps Division move. Currently 15-17% of revenue (estimated), it grows with installed base. Nuclear pumps are explicitly cited as 'surely' contributing meaningfully to SupremeServ profitability (Rajesh Kulkarni, SupremeServ Head, Nov 2025 concall). The service intensity of nuclear and FGD pumps means each deployed unit generates a long revenue tail.

Across 12 years it has been between 11.0% and 14.0%, and FY25's 14.0% is the highest of them.

Why the margin moved: operating margin changed −1.9 percentage points on the year while gross margin changed +0.6 points. So the drop came mostly from costs below the gross margin, such as staff and overheads, measured against sales.

When margins are at a record, every ratio built on profit looks better than usual, so watch whether they hold.

Over the last 3 years, 58% of KSB Ltd's reported profit came in as cash from its operations, a gap worth watching. In FY25 it brought in ₹93.0 Cr of operating cash against ₹270 Cr of profit. After ₹119 Cr of spending on assets, free cash was −₹26.0 Cr: it spent more than its operations brought in.

The profit and loss account shows what was earned. The cash-flow statement shows the cash that actually came in. Comparing operating cash flow with profit is one of the best checks that a profit is real.

Cash-flow figures here are yearly, because quarterly cash statements are not published, so this section changes once a year.

Why 58% of profit came in as cash: the cash cycle got 66 days longer between FY20 and FY25, so more of each rupee of profit waits in the business before it arrives. When less than 70% of profit comes in as cash, it is the thing to watch on this page.

What to look at next: less of the profit turns into cash than it should, and the cash cycle is 66 days longer. The next section looks at where the cash is stuck.

KSB Ltd's cash cycle, the days between paying suppliers and getting paid by customers, was 204 days in FY25, up from 138 days in FY20. It spent ₹341 Cr on assets over the last 3 years. Customers take 118 days to pay, and stock sits for 197 days on average.

Working capital is the cash tied up between paying suppliers and getting paid. Debtor days: how long customers take to pay. Inventory days: how long stock sits. The cash cycle: the whole loop, in days of sales.

At FY25 sales of ₹2,696 Cr, each day of that cycle ties up about ₹7.4 Cr, so roughly ₹1,507 Cr is tied up in the business at any time.

FY25: customers took 118 days to pay and stock sat for 197 days, about 6.5 months of sales sitting as stock, for a full cycle of 204 days, longer than FY20's 138.

The full loop: cash goes out to suppliers and production on day 0. Stock sits for 197 days. Customers pay about 118 days after that. Suppliers are paid at 111 days. Together that makes the 204-day cycle.

Spending on assets: ₹341 Cr over the last 3 years, against ₹162 Cr of depreciation (the yearly wear and tear on existing assets). So it is building well beyond replacing what wears out. Work still in progress is ₹92.0 Cr (FY25): assets paid for that are not earning yet.

In short: cash is getting stuck in the daily cycle, so watch the cycle more than the profit.

KSB Ltd's P/E is 43.2×, in the middle of its own history: higher than 66% of past readings. Its usual P/E (the middle reading) is 37.7×, over 11 years of weekly prices. This compares the share price with the company’s own past. It does not say what the business is worth.

P/E is the share price divided by a year's profit per share: how many rupees the market pays for each rupee of yearly profit.

The P/E here, and its history, use a profit figure that can leave out one-off items, so it can differ from a P/E worked out on the quarterly results. Those results' earnings per share for the four quarters to Jun 2026 add up to ₹14.11.
