RDB Infrastructure and Power has paid no dividend on the NSE since 1 April 2021, the start of the period we checked.

Not in its latest year. RDB Infrastructure and Power Ltd paid out 0% of its profit as dividends in FY25. It did pay a dividend in 2 of its last 12 reported years, so there is a history but no current dividend.

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

RDB Infrastructure and Power is not on any of our India lists this week.

RDB Infrastructure and Power Ltd earned ₹2.4 Cr of net profit in the Dec 2025 quarter, +40.5% on the same quarter a year earlier. That is the 3rd quarter in a row of profit growth. Full-year FY25 profit was ₹6.0 Cr. That is 12.3% of the quarter's revenue. The same quarter a year earlier earned ₹1.7 Cr.

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

1 of the last 12 reported quarters were loss-making.

For the full year, FY25 profit was ₹6.0 Cr (+100.0% on the year before).

Why profit moved: revenue changed −18.4% on a year earlier and the margin moved −7.2 percentage points. Sales did the work while the margin got thinner.

On average over the last four quarters, profit changed +102.1% and revenue +3.6%. Profit is growing faster than sales: fixed costs are spread over more sales, so each extra rupee of revenue adds more to profit.

RDB Infrastructure and Power Ltd reported ₹19.7 Cr of revenue in the Dec 2025 quarter, −18.4% on the same quarter a year earlier. Over 10 years it has grown 11.6% a year on average. The last full year, FY25, came in at ₹108 Cr. The last four reported quarters add to ₹126 Cr.

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

FY25 revenue was ₹108 Cr, +61.2% on the year before.

Recent pace: the last four quarters grew +3.6% on average, against 11.6% 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 +1.8%, against +30.7% a year over the last 8 quarters (rolling over); profit over the last 12 months grew +118.2%, against +42.3% a year (accelerating).

RDB Infrastructure and Power Ltd's operating margin was −1.6% in the Dec 2025 quarter, 7.2 percentage points lower than the same quarter a year ago. Across 12 years it has been between 2.0% and 27.0%. 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 −7.2 percentage points on the year while gross margin changed −5.5 points. So the drop came mostly from the gross margin, which means input costs and prices charged.

Over the last 3 years RDB Infrastructure and Power Ltd's operations used more cash than they brought in, so cash conversion was −408%, a gap worth watching. In FY25 its operations used ₹82.0 Cr of cash, against ₹6.0 Cr of profit.

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.

After ₹0.0 Cr of spending on assets, free cash was −₹82.0 Cr: it spent more than its operations brought in.

Cash-flow figures here are yearly, because quarterly cash statements are not published, so this section changes once a year.

Why: the cash figure is clear, but the day counts behind it are not in our data, so we show it without guessing the reason.

What to look at next: it spends almost nothing on new assets, so the cash goes on running the business. The next section shows the spending figures.

RDB Infrastructure and Power Ltd's customer, stock and supplier day counts come out in the thousands of days on sales this small (₹108 Cr in FY25), so no cash-cycle chart is drawn and this section looks at its spending on assets instead. It spent ₹0.0 Cr on assets over the last 3 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.

Spending on assets: ₹0.0 Cr over the last 3 years. Work still in progress is ₹0.0 Cr (FY25): assets paid for that are not earning yet.

In short: almost nothing is being spent on new assets, so the cash goes on running the business.

RDB Infrastructure and Power Ltd's P/E is 97.8×, near the high end of its own history: higher than 80% of past readings. Its usual P/E (the middle reading) is 46.1×, over 9.9 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 Dec 2025 add up to ₹0.48.

Why the multiple is where it is: over the past year earnings per share moved +100.0% while the price moved −70.3%. 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 +34.2% a year; about +29.3% a year came from earnings growth and about +4.9 percentage points from the multiple (the market paying more); over 10 years the price moved +13.3% a year; about +27.9% a year came from earnings growth and about −14.6 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 high against its own past, so the earnings trend underneath matters more than the multiple.

RDB Infrastructure and Power Ltd's business is giving mixed signals. There is no clear direction across the growth lines, with ROCE rising at 7.0%; each line tells part of the story. This is based on 9 quarters of 3 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.
