Prostarm Info Systems share price today

Prostarm Info Systems Ltd's share price was ₹136.39 at the close on 4 November 2026. It has been falling for 37 weeks. That is 3.0% below its average price over the last 200 trading days. In the last 52 weeks it traded between ₹115 and ₹194, and at that close it sat 27% of the way up from that low.

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 Prostarm Info Systems Ltd is in stage 4. The phase helps read everything below.

Over the past 13 weeks it has done better than the NIFTY 500, and it has stayed ahead for 1 week in a row.

Over the last 1 year the share price moved +21% while the NIFTY 500 moved −6%, so it is ahead of the index over that whole period. 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.

Earlier

• Results for April to June 2026: Revenue up 38.5% and profit up 150.3% on a year earlier.

Prostarm Info Systems has paid no dividend on the NSE since its first NSE close in our records (6 June 2025), the start of the period we checked.

No. Prostarm Info Systems Ltd paid out 0% of its profit as dividends in each of its last 5 reported years, so there is no payout history to show. That comes from the filed annual statements, not an estimate.

From the NSE corporate-actions record, read 5 November 2026.

On the call for April to June 2026, held on 29 September 2026, Prostarm Info Systems' management guided: Current-year BESS revenue approximately ₹75 crore.

“We will not be focusing on the utility segment. Utility is a different chapter, and you are well aware that there is significant disruption in that area.”Abhishek Agarwal, on the call for April to June 2026

What management guided

• Next-year BESS capacity utilization 25-30%.
• Next-year company growth around 25% and operating margin 13-14%.
• Operating cash flow expected to improve significantly by the end of the current financial year.
• BESS exports to follow approval of approximately 10 samples next month; non-Chinese PCS tie-up and reverse integration to advance, timing unstated.

Management’s own plans and goals, from our notes of the call. A plan is not a result.

When Prostarm Info Systems reports July to September 2026, these are the 4 checks that show whether the story is still on course. First: BESS export sample approvals - check whether the process produces disclosed geographies and recurring orders.

Prostarm Info Systems is not on any of our India lists this week.

Prostarm Info Systems Ltd earned ₹4.6 Cr of net profit in the Jun 2026 quarter, +150.3% on the same quarter a year earlier. That is the 3rd quarter in a row of profit growth. Full-year FY26 profit was ₹33.0 Cr. Over 4 years profit has grown 31.6% a year on average. That is 6.0% 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 ₹1.8 Cr.

For the full year, FY26 profit was ₹33.0 Cr (+13.8% on the year before).

Why profit moved: revenue changed +38.5% on a year earlier and the margin moved +1.4 percentage points. Sales did the work, and the margin was about flat.

On average over the last four quarters, profit changed +56.8% and revenue +35.7%. Profit is growing faster than sales: fixed costs are spread over more sales, so each extra rupee of revenue adds more to profit.

Prostarm Info Systems Ltd reported ₹76.0 Cr of revenue in the Jun 2026 quarter, +38.5% on the same quarter a year earlier. That is the 3rd quarter in a row with growth on the year before. Over 4 years it has grown 22.6% a year on average. The last full year, FY26, came in at ₹386 Cr.

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

The last four reported quarters add to ₹407 Cr.

FY26 revenue was ₹386 Cr, +10.0% on the year before.

Recent pace: the last four quarters grew +35.7% on average, against 22.6% a year over the longer run, so this year is growing faster than its own long-run rate.

Prostarm Info Systems Ltd's operating margin was 8.5% in the Jun 2026 quarter, 1.4 percentage points higher than the same quarter a year ago. Across 5 years it has been between 9.0% and 14.0%. The latest quarter is below every full year in that period.

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 +1.4 percentage points on the year while gross margin changed −2.7 points. So the gain came mostly from the gross margin, which means input costs and prices charged.

Over the last 3 years Prostarm Info Systems Ltd's operations used more cash than they brought in, so cash conversion was −71%, a gap worth watching. In FY26 its operations used ₹49.0 Cr of cash, against ₹33.0 Cr of profit. After ₹39.0 Cr of spending on assets, free cash was −₹88.0 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 −71% of profit came in as cash: the cash cycle got 117 days longer between FY22 and FY26, 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 117 days longer. The next section looks at where the cash is stuck.

Prostarm Info Systems Ltd's cash cycle, the days between paying suppliers and getting paid by customers, was 146 days in FY26, up from 29 days in FY22. It spent ₹50.0 Cr on assets over the last 3 years. Customers take 241 days to pay, and stock sits for 96 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 ₹386 Cr, each day of that cycle ties up about ₹1.1 Cr, so roughly ₹154 Cr is tied up in the business at any time.

FY26: customers took 241 days to pay and stock sat for 96 days, about 3.2 months of sales sitting as stock, for a full cycle of 146 days, longer than FY22's 29.

The full loop: cash goes out to suppliers and production on day 0. Stock sits for 96 days. Customers pay about 241 days after that. Suppliers are paid at 191 days. Together that makes the 146-day cycle.

Spending on assets: ₹50.0 Cr over the last 3 years, against ₹8.0 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 ₹21.0 Cr (FY26): 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.

Prostarm Info Systems Ltd's P/E is 22.5×, near the low end of its own history: it has been lower only 13% of the time. Its usual P/E (the middle reading) is 27.5×, over 1 year 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 −18.9% while the price moved −15.8%. The price did better than earnings, which pushed the multiple up within its own range.

In short: the multiple is low against its own past, so the earnings trend underneath matters more than the multiple.

Prostarm Info Systems Ltd's business trend cannot be read yet. There are fewer than eight usable quarters of growth figures, so there is not enough history to read the trend. This is based on 6 quarters of 1 measure, with some gaps.

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: with too little history, we say so rather than guess a direction.

One or more growth lines have an extreme jump caused by comparing with a near-zero or loss-making quarter. Those jumps are capped before reading and drawn at the edge of the chart, so one odd quarter does not decide the result.

There are fewer than eight usable quarters, so this page does not guess a direction from so little history.

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.

Prostarm Info Systems Ltd earned a ROCE of 18% in FY26. Its return on capital used (ROIC) is 2.1 percentage points below its cost of capital, so growth here does not yet pay for the capital it uses. It comes from a 8.5% net margin and 0.72× 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 8.5% net margin × 0.72× asset turnover × 1.87× leverage (assets divided by equity) ≈ 11.4% on equity. The margin does its share; borrowing is a big part of it.

The key test, return on capital used minus the cost of capital: 9.9% − 12.0% = −2.1 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. Negative: growth at these returns loses value until returns improve.

The 9.9% ROIC above is the latest reading, as reported. The yearly chart below shows FY26 at 13.5%, and the quarterly chart works out each 12-month window from the quarterly figures, so the readings differ by date, not by method.

Prostarm Info Systems Ltd has total debt of ₹93.0 Cr against shareholder equity of ₹287 Cr as of Jun 2026, so its debt is 0.32× its equity. Year by year, that ratio went from 0.64 in FY25 to 0.32 in FY26. Keep that borrowing in mind when reading the returns on this page.

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.

Foreign institutions cut their stake in Prostarm Info Systems Ltd by 3.7 percentage points over 6 quarters, the biggest change among its owners. Foreign institutions now own 0.4% of the company. Domestic institutions moved −1.3 points over the same period, to 0.9%. 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: Foreign institutions: −3.7 points over 6 quarters, to 0.4%; Domestic institutions: −1.3 points over 6 quarters, to 0.9%; Promoters: +0.0 points over 6 quarters, to 72.8%.

Why the owners changed: foreign institutions drove it (−3.7 points), together with domestic institutions (−1.3 points). They reduced their stake.

For Prostarm Info Systems 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.

50.8 out of 100, rank 20 of 63 in Trading, with 64% of the evidence available.

Prostarm Info Systems Ltd scores 50.8 out of 100 against the 63 companies it is compared with in Trading, ranking 20. 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: 17.2 + 14.7 + 10.3 + 8.6 = 50.8. 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.

Prostarm Info Systems ranks 20 of 63 Trading companies on the 4-Factor Sector Score, with 50.8 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.
