This page treats a rise as over when the price closes below its 200-day average on two Fridays in a row. ## What changed at Clean Science & Technology this quarter? Three changes stood out: lowest operating margin in 16 quarters, indian funds and insurers (DIIs) cut their stake for 3 quarters in a row and highest quarterly revenue in 16 quarters. 1. Lowest operating margin in 16 quarters Operating margin was 31% in the September 2026 quarter, against 36% a year earlier. Why: Margins fell because the cost of key raw materials jumped. The company held its own prices to keep market share, so it absorbed those extra costs. Next results: check whether Chinese competitors raise their prices, because management says that is needed before it can lift its own. From the earnings call on 31 Oct 2026. 2. Indian funds and insurers (DIIs) cut their stake for 3 quarters in a row From 19.8% to 15.1% of the company by the September 2026 quarter. 3. Highest quarterly revenue in 16 quarters Revenue of ₹299 crore in the September 2026 quarter is the highest of the last 16 quarters. Why: Revenue hit a record because the company sold the most goods it ever has. HALS, an additive product line, also grew fast and added more to sales. From the earnings call on 31 Oct 2026. ## What are Clean Science & Technology's latest quarterly results? For July to September 2026 (the quarter ended 30 September 2026), Clean Science & Technology reported revenue of ₹299 crore, up 22.0% from ₹245 crore a year earlier, and a profit of ₹56.0 crore, up 1.8% from ₹55.0 crore. ### Clean Science & Technology results: July to September 2026 against a year earlier

Clean Science & Technology is not on any of our India lists this week. ## Is Clean Science & Technology profitable? Clean Science & Technology Ltd earned ₹56.0 Cr of net profit in the Sep 2026 quarter, +1.8% on the same quarter a year earlier. That is the 2nd quarter in a row of profit growth. Full-year FY26 profit was ₹230 Cr. Over 8 years profit has grown 21.3% a year on average. That is 18.7% of the quarter's revenue. The same quarter a year earlier earned ₹55.0 Cr. For the full year, FY26 profit was ₹230 Cr (−12.9% on the year before). Why profit moved: revenue changed +22.0% on a year earlier and the margin moved −5.0 percentage points. Sales did the work while the margin got thinner. On average over the last four quarters, profit changed −11.5% and revenue +4.5%. Profit is growing slower than sales: rising costs are taking part of the growth. ## How much revenue does Clean Science & Technology make, and is it growing? Clean Science & Technology Ltd reported ₹299 Cr of revenue in the Sep 2026 quarter, +22.0% on the same quarter a year earlier. That is the 2nd quarter in a row with growth on the year before. Over 8 years it has grown 18.8% a year on average. The last full year, FY26, came in at ₹957 Cr. The last four reported quarters add to ₹1,036 Cr. FY26 revenue was ₹957 Cr, −1.0% on the year before. Recent pace: the last four quarters grew +4.5% on average, against 18.8% 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 +4.3%, against +8.2% a year over the last 8 quarters (rolling over); profit over the last 12 months grew −12.1%, against −5.0% a year (rolling over). ## How much of every ₹100 of sales does Clean Science & Technology keep? Clean Science & Technology Ltd's operating margin was 31.0% in the Sep 2026 quarter, 5.0 percentage points lower than the same quarter a year ago. Across 9 years it has been between 31.0% and 51.0%. The latest quarter is within that range. Why the margin moved: operating margin changed −4.9 percentage points on the year while gross margin changed −3.4 points. So the drop came mostly from the gross margin, which means input costs and prices charged. ## Is Clean Science & Technology's profit turning into cash? Over the last 3 years, 98% of Clean Science & Technology Ltd's reported profit came in as cash from its operations, so the profit is backed by cash. In FY26 it brought in ₹275 Cr of operating cash against ₹230 Cr of profit. After ₹211 Cr of spending on assets, ₹64.0 Cr was left over as free cash. Cash-flow figures here are yearly, because quarterly cash statements are not published, so this section changes once a year. Why 98% of profit came in as cash: the cash cycle got 89 days longer between FY21 and FY26, so more of each rupee of profit waits in the business before it arrives. What to look at next: the bigger use of cash is spending on new assets, at 3.1× depreciation over three years. The next section checks what that spending is building. ## Where does Clean Science & Technology's cash go? Clean Science & Technology Ltd's cash cycle, the days between paying suppliers and getting paid by customers, was 118 days in FY26, up from 29 days in FY21. It spent ₹591 Cr on assets over the last 3 years. Customers take 79 days to pay, and stock sits for 157 days on average. At FY26 sales of ₹957 Cr, each day of that cycle ties up about ₹2.6 Cr, so roughly ₹309 Cr is tied up in the business at any time. FY26: customers took 79 days to pay and stock sat for 157 days, about 5.2 months of sales sitting as stock, for a full cycle of 118 days, longer than FY21's 29. The full loop: cash goes out to suppliers and production on day 0. Stock sits for 157 days. Customers pay about 79 days after that. Suppliers are paid at 118 days. Together that makes the 118-day cycle. Spending on assets: ₹591 Cr over the last 3 years, against ₹193 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 ₹118 Cr (FY26): assets paid for that are not earning yet. In short: the cash is going into new capacity, not getting stuck in the daily cycle. The question is whether the new capacity earns. ## What is Clean Science & Technology's P/E ratio, and how does it compare with its own history? Clean Science & Technology Ltd's P/E is 29.9×, about the lowest it has ever been. Its usual P/E (the middle reading) is 56.1×, over 5.3 years of weekly prices. This compares the share price with the company’s own past. It does not say what the business is worth. Why the multiple is where it is: over the past year earnings per share moved −13.1% while the price moved −30.0%. Earnings did better than the price, which pulled the multiple down within its own range. Where the price move came from: over 5 years the price moved −20.5% a year; about +3.3% a year came from earnings growth and about −23.8 percentage points from the multiple (the market paying less). The split is approximate (price return minus earnings growth). It shows how much of the move came from the market paying a different multiple. In short: the multiple is low against its own past, so the earnings trend underneath matters more than the multiple. ## Is the Clean Science & Technology business getting better or worse? Clean Science & Technology Ltd's business is getting worse. Profit and EPS growth are shrinking: profit growth is −12.1% in the latest quarter, against +8.6% at its best in 12 quarters, with ROCE falling at 20.5%. This is based on 12 quarters of 4 measures. Why it matters: falling lines mean any ratio below that looks low should be read with that direction in mind. ## How much does Clean Science & Technology earn on its capital? Clean Science & Technology Ltd earned a ROCE of 21% in FY26. Its return on capital used (ROIC) is 4.8 percentage points above its cost of capital, so growth here adds value, not just size. It comes from a 24.0% net margin and 0.54× asset turnover (sales divided by assets). Why the return is what it is (FY26): a 24.0% net margin × 0.54× asset turnover × 1.12× leverage (assets divided by equity) ≈ 14.5% on equity. The margin does most of the work; borrowing plays a small part, so this return is earned, not borrowed. The key test, return on capital used minus the cost of capital: 16.8% − 12.0% = +4.8 percentage points. The 12.0% is a standard assumption for the cost of capital in India, not an estimate for this company. Read the sign and size of the gap, not the decimals. Positive but thin: it creates value with little room for error. The 16.8% ROIC above is the latest reading, as reported. The yearly chart below shows FY26 at 18.2%, and the quarterly chart works out each 12-month window from the quarterly figures, so the readings differ by date, not by method. ## Does Clean Science & Technology have too much debt? Clean Science & Technology Ltd has total debt of ₹2.0 Cr against shareholder equity of ₹1,584 Cr as of Jun 2026, so its debt is 0.00× its equity, which is very little. Year by year, that ratio went from 0.00 in FY22 to 0.00 in FY26. So the returns on this page come from the business, not from borrowed money. ## What is the Clean Science & Technology shareholding pattern? Promoters cut their stake in Clean Science & Technology Ltd by 23.7 percentage points over 8 quarters, the biggest change among its owners. Promoters now own 51.3% of the company. Domestic institutions moved +10.3 points over the same period, to 15.1%. This uses the four owner groups that companies report every quarter; nothing is guessed between filings. Over the last two years: Promoters: −23.7 points over 8 quarters, to 51.3%; Domestic institutions: +10.3 points over 8 quarters, to 15.1%; Foreign institutions: +7.9 points over 8 quarters, to 13.7%. Why the owners changed: promoters drove it (−23.7 points), with the other side taken by domestic institutions (+10.3 points). They reduced their stake. ## How far is Clean Science & Technology from balance-sheet trouble? For Clean Science & Technology Ltd, the Z-score is not available, so we say so rather than guess one. It estimates how far the balance sheet is from trouble; it is not a forecast of failure. The debt, cash-flow and return sections show the balance-sheet figures we do have, each with its own date. ## How does Clean Science & Technology rank in its industry? 38.1 out of 100, rank 29 of 30 in Speciality Chemicals, with 85% of the evidence available. Clean Science & Technology Ltd scores 38.1 out of 100 against the 30 companies it is compared with in Speciality Chemicals, ranking 29. The evidence is balanced: no factor stands out, so another reported quarter is needed before the picture is clearer. The four parts add up to the total exactly: 5 + 18 + 7.1 + 8 = 38.1. This is the same number shown on the industry page; it is worked out once for the whole group and read here. What would change it: The score would fall if profit growth turns negative or margins stop improving while the share price lags its sector. ## Which companies is Clean Science & Technology compared with? Clean Science & Technology ranks 29 of 30 Speciality Chemicals companies on the 4-Factor Sector Score, with 38.1 out of 100. 1.

Missing figures are not scored as bad. They lower the confidence and pull the final score toward the middle. Relative strength counts only when the company has a reading for this week; with no reading, that factor is left out and its 20 points are shared across the other three in proportion. PEG is not shown when the ratio cannot mean anything: the company must be making a profit, its price-to-earnings must be positive, and its three-year earnings growth must fall between 5% and 60%. Dividing a price multiple by a loss, or by growth measured off a tiny base, produces a number that looks precise and tells you nothing. Under relative strength, one mark per week shows the last 12 weeks: a mark is filled where the company led NIFTY 500 by 5% or more over the 13 weeks ending that week, which is the same test used everywhere on this site. Price stage places the company on the same six-step path the industry is placed on (basing, turning, breaking out, leader, fading, asleep), read from how many weeks running it has led NIFTY 500 and whether that lead is growing or shrinking. It describes where the share price stands, not the direction of earnings, and it is not a recommendation; it is left blank for a company whose weekly history is too short or too stale to read. The figures in this ranking come from the industry comparison: results through the Sep 2026 quarter, and the P/E at that quarter's end. The sections above use the latest weekly price, so a P/E or return there can differ a little from the one here. The stage words in this ranking (such as losing its lead or breaking out) describe the lead over the index, not the price phase in the price section.
