Clean Science & Technology share price today

Clean Science & Technology Ltd's share price was ₹656.40 at the close on 4 November 2026. It has been falling for 63 weeks. That is 21.1% below its average price over the last 200 trading days. In the last 52 weeks it traded between ₹656 and ₹938, and at that close it was at the low of that range.

A share price tends to move through four phases: moving sideways (stage 1), rising (stage 2), stalling near a high (stage 3) and falling (stage 4). Today Clean Science & Technology Ltd is in stage 4. The phase helps read everything below.

Over the past 13 weeks it has done worse than the NIFTY 500, and it has been behind for 1 week running.

Over the last 5.3 years the share price moved −60% while the NIFTY 500 moved +61%, so it is behind the index over that whole period. It was last ahead over 13 weeks in the week of 30 October 2026. The chart above shows the 13-week comparison for every week.

This page treats a rise as over when the price closes below its 200-day average on two Fridays in a row.

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.

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.

From the call for July to September 2026, 31 October 2026.

When Clean Science & Technology reports October to December 2026, these are the 3 checks that show whether the story is still on course. First: HALS utilization lift toward flagged range on higher-grade volumes - check quarterly utilization disclosure.

Clean Science & Technology is not on any of our India lists this week.

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.

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

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.

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.

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

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).

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.

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 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.

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.

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 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.

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.

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 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.

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.

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.

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.

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.

Every business is somewhere on a path of getting better or worse, and this section names where. The last 12 quarters of growth in revenue, profit and earnings per share, plus the return the business earns on its capital, are read as lines. Getting worse: the lines are falling. Turning around: a low point has just formed and the last few quarters are rising from it. Getting better: the rise from the low has lasted. Growing steadily: steady growth with healthy returns. Slowing from a peak: still high, but slowing. When the lines disagree the result is mixed; too little history means no reading. CAGR (compound annual growth rate) is the steady yearly rate that would turn the starting value into the latest one. It is the fairest way to compare growth over different periods. If the 1-year figure is much bigger than the 10-year one, recent growth is running faster than the long-run trend. A dash means there is no figure for that period, or the starting year was a loss, where a growth rate means nothing.

Why it matters: falling lines mean any ratio below that looks low should be read with that direction in mind.

Compound annual growth rate (%)

Compound annual growth rate over each period, %. Revenue, profit and EPS come from yearly figures; the share price row is price growth over the same periods. A dash means no figure for that period, or the starting year was a loss.

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).

Return on capital employed (ROCE) is the profit the whole business earns on all the money in it, from shareholders and lenders together. It is the best single test of whether growth adds value or just size.

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.

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.

Debt-to-equity shows how much of the business is paid for with borrowed money. Lower is safer, and the direction matters as much as the level.

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.

Who owns the company each quarter: promoters (the founders or controlling owners), foreign institutions, domestic institutions such as mutual funds, and the public. When people close to the business steadily raise their stake, that is worth noticing; a quiet list is also an answer.

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.

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.

The Z-score estimates how far a company is from balance-sheet trouble. Above about 3 is safe; below about 1.8 is the danger zone. It was built for manufacturers, so it is not used for banks and lenders.

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.

Clean Science & Technology ranks 29 of 30 Speciality Chemicals companies on the 4-Factor Sector Score, with 38.1 out of 100.

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.
