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

2. Operating margin up 9 points on a year earlier

   54% in the June 2026 quarter, from 45%.

   Why: The margin rose because the company did less construction work and more work from toll roads and toll-road investment trusts, which earn much higher margins.

   Next results: check whether the higher margin holds, since BOT margins can move with major maintenance timing.

IRB Infrastructure Developers Ltd earned ₹260 Cr of net profit in the Sep 2026 quarter, +84.4% on the same quarter a year earlier. That is the 3rd quarter in a row of profit growth. Full-year FY26 profit was ₹850 Cr. Over 10 years profit has grown 2.9% a year on average. That is 13.7% 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 ₹141 Cr.

For the full year, FY26 profit was ₹850 Cr (−86.9% on the year before).

Why profit moved: revenue changed +8.3% on a year earlier and the margin moved +3.0 percentage points. Most of the change came from keeping more of each sale.

On average over the last four quarters, profit changed +19.3% and revenue −1.9%. Profit is growing faster than sales: fixed costs are spread over more sales, so each extra rupee of revenue adds more to profit.

IRB Infrastructure Developers Ltd reported ₹1,897 Cr of revenue in the Sep 2026 quarter, +8.3% on the same quarter a year earlier. That is the 2nd quarter in a row with growth on the year before. Over 10 years it has grown 4.1% a year on average. The last full year, FY26, came in at ₹7,648 Cr.

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

The last four reported quarters add to ₹7,832 Cr.

FY26 revenue was ₹7,648 Cr, +0.5% on the year before.

Recent pace: the last four quarters grew −1.9% on average, against 4.1% 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 −2.4%, against +2.4% a year over the last 8 quarters (rolling over); profit over the last 12 months grew −83.7%, against +32.0% a year (rolling over).

IRB Infrastructure Developers Ltd's operating margin was 56.0% in the Sep 2026 quarter, 3.0 percentage points higher than the same quarter a year ago. Across 13 years it has been between 41.0% and 58.0%. 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 +2.8 percentage points on the year while gross margin changed +1.6 points. So the gain came mostly from costs below the gross margin, such as staff and overheads, measured against sales.

Over the last 3 years, 102% of IRB Infrastructure Developers Ltd's reported profit came in as cash from its operations, so the profit is backed by cash. In FY26 it brought in ₹2,098 Cr of operating cash against ₹850 Cr of profit. After ₹425 Cr of spending on assets, ₹1,673 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 102% of profit came in as cash: the cash cycle got 403 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: no single use of cash stands out. The next section checks both the cash tied up in daily operations and the spending on assets.

IRB Infrastructure Developers Ltd's cash cycle, the days between paying suppliers and getting paid by customers, was 67 days in FY26, up from −336 days in FY21. It spent ₹587 Cr on assets over the last 3 years. Customers take 7 days to pay, and stock sits for 199 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 ₹7,648 Cr, each day of that cycle ties up about ₹21.0 Cr, so roughly ₹1,404 Cr is tied up in the business at any time.

FY26: customers took 7 days to pay and stock sat for 199 days, about 6.5 months of sales sitting as stock, for a full cycle of 67 days, longer than FY21's −336.

The full loop: cash goes out to suppliers and production on day 0. Stock sits for 199 days. Customers pay about 7 days after that. Suppliers are paid at 139 days. Together that makes the 67-day cycle.

Spending on assets: ₹587 Cr over the last 3 years, against ₹3,175 Cr of depreciation (the yearly wear and tear on existing assets). So it is spending about what it takes to replace what wears out, or less. Work still in progress is ₹4.0 Cr (FY26): assets paid for that are not earning yet.

In short: neither the daily cycle nor new spending is soaking up the cash, so the picture is fairly clean.

IRB Infrastructure Developers Ltd's P/E is 18.8×, in the middle of its own history: higher than 46% of past readings. Its usual P/E (the middle reading) is 21.7×, 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 Sep 2026 add up to ₹0.89.
