2. Highest quarterly profit in 17 quarters

   Profit of ₹4 crore in the September 2026 quarter is the highest of the last 17 quarters.

From the call for July to September 2026, 27 October 2026.

When RIR Power Electronics reports October to December 2026, these are the 4 checks that show whether the story is still on course. First: Odisha building and fire clearances - check whether installation and internal testing convert into commercial production.

RIR Power Electronics is on one of our India lists: Semiconductor stocks.

RIR Power Electronics Ltd earned ₹4.5 Cr of net profit in the Sep 2026 quarter, +41.3% on the same quarter a year earlier. That is the 2nd quarter in a row of profit growth. Full-year FY26 profit was ₹7.0 Cr. Over 10 years profit has grown 21.5% a year on average. That is 13.1% 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 ₹3.1 Cr.

For the full year, FY26 profit was ₹7.0 Cr (−12.5% on the year before).

Why profit moved: revenue changed +32.5% on a year earlier and the margin moved −3.4 percentage points. Sales did the work while the margin got thinner.

On average over the last four quarters, profit changed +2.1% and revenue +13.6%. Profit is growing slower than sales: rising costs are taking part of the growth.

RIR Power Electronics Ltd reported ₹34.0 Cr of revenue in the Sep 2026 quarter, +32.5% 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 12.1% a year on average. The last full year, FY26, came in at ₹91.0 Cr.

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

The last four reported quarters add to ₹105 Cr.

FY26 revenue was ₹91.0 Cr, +5.8% on the year before.

Recent pace: the last four quarters grew +13.6% on average, against 12.1% a year over the longer run, so this year is growing faster than its own long-run rate.

Is growth speeding up? Revenue over the last 12 months grew +13.3%, against +17.6% a year over the last 8 quarters (rolling over); profit over the last 12 months grew +6.9%, against +3.7% a year (accelerating).

RIR Power Electronics Ltd's operating margin was 13.6% in the Sep 2026 quarter, 3.4 percentage points lower than the same quarter a year ago. Across 12 years it has been between 8.0% and 15.0%. 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 −3.4 percentage points on the year while gross margin changed −2.8 points. So the drop came mostly from the gross margin, which means input costs and prices charged.

Over the last 3 years RIR Power Electronics Ltd's operations used more cash than they brought in, so cash conversion was −104%, a gap worth watching. In FY26 its operations used ₹30.0 Cr of cash, against ₹7.0 Cr of profit. After ₹27.0 Cr of spending on assets, free cash was −₹57.0 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 −104% of profit came in as cash: the cash cycle got 85 days shorter between FY21 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 36.0× depreciation over three years. The next section checks what that spending is building.

RIR Power Electronics Ltd's cash cycle, the days between paying suppliers and getting paid by customers, was 199 days in FY26, down from 284 days in FY21. It spent ₹108 Cr on assets over the last 3 years. Customers take 85 days to pay, and stock sits for 163 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 ₹91.0 Cr, each day of that cycle ties up about ₹0.2 Cr, so roughly ₹50.0 Cr is tied up in the business at any time.

FY26: customers took 85 days to pay and stock sat for 163 days, about 5.4 months of sales sitting as stock, for a full cycle of 199 days, shorter than FY21's 284.

The full loop: cash goes out to suppliers and production on day 0. Stock sits for 163 days. Customers pay about 85 days after that. Suppliers are paid at 50 days. Together that makes the 199-day cycle.

Spending on assets: ₹108 Cr over the last 3 years, against ₹3.0 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 ₹98.0 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.

RIR Power Electronics Ltd's P/E is 124.2×, near the high end of its own history: higher than 72% of past readings. Its usual P/E (the middle reading) is 57.7×, over 10 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.
