Earlier

• Results for April to June 2026: Revenue up 102.7% and profit up 136.8% on a year earlier.

TAC Infosec has paid no dividend on the NSE since its first NSE close in our records (5 April 2024), the start of the period we checked.

No. TAC Infosec Ltd paid out 0% of its profit as dividends in each of its last 3 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 July 2026, TAC Infosec's management guided: Following completion of the proposed transaction, prioritize integrating the technology, IP and business operations into one safety, privacy and insurance product.

From the call for April to June 2026, 29 July 2026.

When TAC Infosec reports July to September 2026, these are the 4 checks that show whether the story is still on course. First: Completion of the proposed Safehouse Technologies acquisition and disclosure of the closing timetable, which was not provided on this call.

TAC Infosec is on one of our India lists: IT stocks.

TAC Infosec Ltd earned ₹8.1 Cr of net profit in the Jun 2026 quarter, +136.8% on the same quarter a year earlier. Full-year FY26 profit was ₹26.0 Cr. Over 2 years profit has grown 108.2% a year on average. That is 40.7% of the quarter's revenue. The same quarter a year earlier earned ₹8.0 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, FY26 profit was ₹26.0 Cr (+73.3% on the year before).

Why profit moved: revenue changed +102.7% on a year earlier and the margin moved +1.6 percentage points. Sales did the work, and the margin was about flat.

On average over the last four quarters, profit changed +80.2% and revenue +76.9%. Profit is growing faster than sales: fixed costs are spread over more sales, so each extra rupee of revenue adds more to profit.

TAC Infosec Ltd reported ₹19.8 Cr of revenue in the Jun 2026 quarter, +102.7% on the same quarter a year earlier. Over 2 years it has grown 117.9% a year on average. The last full year, FY26, came in at ₹57.0 Cr.

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

FY26 revenue was ₹57.0 Cr, +90.0% on the year before.

Recent pace: the last four quarters grew +76.9% on average, against 117.9% a year over the longer run, so this year is growing slower than its own long-run rate.

TAC Infosec Ltd's operating margin was 48.2% in the Jun 2026 quarter, 1.6 percentage points higher than the same quarter a year ago. Over the last four quarters it has moved −2.8 percentage points. Across 3 years it has been between 50.0% and 57.0%. 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 −2.5 percentage points on the year while gross margin changed +0.0 points. So the drop came mostly from costs below the gross margin, such as staff and overheads, measured against sales.

Over the last 3 years, 57% of TAC Infosec Ltd's reported profit came in as cash from its operations, a gap worth watching. In FY26 it brought in ₹10.0 Cr of operating cash against ₹26.0 Cr of profit. After ₹10.0 Cr of spending on assets, ₹0.0 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 57% of profit came in as cash: the cash cycle got 211 days shorter between FY24 and FY26, so cash that used to wait in the business now arrives sooner. When less than 70% of profit comes in as cash, it is the thing to watch on this page.

What to look at next: the bigger use of cash is spending on new assets, at 6.8× depreciation over three years. The next section checks what that spending is building.

TAC Infosec Ltd's cash cycle, the days between paying suppliers and getting paid by customers, was 145 days in FY26, down from 356 days in FY24. It spent ₹27.0 Cr on assets over the last 2 years.

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 ₹57.0 Cr, each day of that cycle ties up about ₹0.2 Cr, so roughly ₹23.0 Cr is tied up in the business at any time.

Spending on assets: ₹27.0 Cr over the last 2 years, against ₹4.0 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 ₹9.0 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.

TAC Infosec Ltd's P/E is 27.3×, about the lowest it has ever been. Its usual P/E (the middle reading) is 78.5×, over 2.4 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 +56.1% while the price moved −54.3%. Earnings did better than the price, which pulled the multiple down within its own range.

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

A quarterly PEG curve, which only the second data source has, is not shown on this page: its two data sources disagree by up to 72% on reported income across 6 comparable periods. When two sources disagree on a figure, we leave it out on purpose. The gap is a choice, not missing data.

TAC Infosec 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 5 quarters of 0 measures, 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.

The return figures here are yearly, not quarterly. They show level and direction only; they can support the growth lines but never decide the reading alone.

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.

TAC Infosec Ltd earned a ROCE of 40% in FY26. We cannot compare its return on capital used with its cost of capital from the data we have. It comes from a 45.6% net margin and 0.59× 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 45.6% net margin × 0.59× asset turnover × 1.16× leverage (assets divided by equity) ≈ 31.2% on equity. The margin does most of the work; borrowing plays a small part, so this return is earned, not borrowed.

The quarterly return lines and the return-on-capital-used (ROIC) line, which only the second data source has, are not shown on this page: its two data sources disagree by up to 72% on reported income across 6 comparable periods. When two sources disagree on a figure, we leave it out on purpose. The gap is a choice, not missing data.

TAC Infosec Ltd had ₹1.0 Cr of borrowings against ₹83.0 Cr of equity in FY26, so its debt is 0.01× its equity. Over 2 years borrowings went from ₹2.0 Cr to ₹1.0 Cr. Over the last 2 of those years it spent ₹27.0 Cr on assets.

Debt-to-equity shows how much of the business is paid for with borrowed money. Interest cover shows how many times operating profit pays the interest bill. Low debt and high cover are the safe combination.

The spending on assets is being paid for from cash, not new debt.

The total-debt and debt-to-equity series, which only the second data source has, are not shown on this page: its two data sources disagree by up to 72% on reported income across 6 comparable periods. When two sources disagree on a figure, we leave it out on purpose. The gap is a choice, not missing data.

Foreign institutions cut their stake in TAC Infosec Ltd by 9.8 percentage points over 6 quarters, the biggest change among its owners. Foreign institutions now own 0.1% of the company. Domestic institutions moved −2.2 points over the same period, to 0.1%. 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: Foreign institutions: −9.8 points over 6 quarters, to 0.1%; Domestic institutions: −2.2 points over 6 quarters, to 0.1%; Promoters: −1.1 points over 6 quarters, to 55.8%.

Why the owners changed: foreign institutions drove it (−9.8 points), together with domestic institutions (−2.2 points). They reduced their stake.

For TAC Infosec Ltd, the Z-score is left out, because it comes from the second data source we could not check, and a safety score is not worth showing when two sources disagree. It estimates how far the balance sheet is from trouble; it is not a forecast of failure.

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.

The debt, cash-flow and return sections show the balance-sheet figures we do have, each with its own date.

58.5 out of 100, rank 59 of 69 in IT - Software, with 48% of the evidence available. It is provisional, so it is ranked below companies with full evidence.

TAC Infosec Ltd scores 58.5 out of 100 against the 69 companies it is compared with in IT - Software, ranking 59. Some evidence is missing, so the score is pulled toward the middle on purpose.

The four parts add up to the total exactly: 20.3 + 20.7 + 9.6 + 7.9 = 58.5. 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.

TAC Infosec ranks 59 of 69 IT - Software companies on the 4-Factor Sector Score, with 58.5 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.
