Over the past 13 weeks it has done better than the NIFTY 500, and it has stayed ahead for 5 weeks in a row.

Over the last 11 years the share price moved +5,228% while the NIFTY 500 moved +251%, 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.

Two changes stood out: revenue up on a year earlier for 4 quarters in a row and highest quarterly revenue in 15 quarters.

1. Revenue up on a year earlier for 4 quarters in a row

   In the June 2026 quarter revenue was ₹1,718 crore, +23.9% on a year earlier.

   Why: Revenue rose because the company worked through a large pile of orders and got more data center work from big cloud companies.

   Next results: check fresh awards and whether new data center orders turn into revenue.

   From the earnings call on 29 Sep 2026.

When Black Box reports July to September 2026, these are the 4 checks that show whether the story is still on course. First: September receivables to normalise versus the March position - check collection timing and project billing in the next print.

Black Box is on 2 of our India lists: Small & mid cap stocks and AI & data centre stocks.

Black Box Ltd earned ₹56.0 Cr of net profit in the Jun 2026 quarter, +19.1% on the same quarter a year earlier. That is the 2nd quarter in a row of profit growth. Full-year FY26 profit was ₹218 Cr. That is 3.3% of the quarter's revenue. The same quarter a year earlier earned ₹47.0 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 ₹218 Cr (+6.3% on the year before).

Why profit moved: revenue changed +23.9% on a year earlier and the margin moved +1.0 percentage points. Sales did the work, and the margin was about flat.

On average over the last four quarters, profit changed +6.6% and revenue +12.4%. Profit is growing slower than sales: rising costs are taking part of the growth.

Black Box Ltd reported ₹1,718 Cr of revenue in the Jun 2026 quarter, +23.9% on the same quarter a year earlier. That is the 4th quarter in a row with growth on the year before. Over 10 years it has grown 21.8% a year on average. The last full year, FY26, came in at ₹6,322 Cr.

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

The last four reported quarters add to ₹6,654 Cr.

FY26 revenue was ₹6,322 Cr, +5.9% on the year before.

Recent pace: the last four quarters grew +12.4% on average, against 21.8% 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 +12.2%, against +4.2% a year over the last 8 quarters (accelerating); profit over the last 12 months grew +6.1%, against +22.6% a year (rolling over).

Black Box Ltd's operating margin was 9.0% in the Jun 2026 quarter, 1.0 percentage points higher than the same quarter a year ago. Its latest full-year margin is the highest it has ever reported. Across 13 years it has been between −25.0% and 9.0%. 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 +0.9 percentage points on the year while gross margin changed +3.5 points. So the gain came mostly from the gross margin, which means input costs and prices charged.

When margins are at a record, every ratio built on profit looks better than usual, so watch whether they hold.

Over the last 3 years, 22% of Black Box Ltd's reported profit came in as cash from its operations, a gap worth watching. In FY26 it brought in ₹84.0 Cr of operating cash against ₹218 Cr of profit. After ₹230 Cr of spending on assets, free cash was −₹146 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 22% of profit came in as cash: the cash cycle got 58 days longer between FY21 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 58 days longer. The next section looks at where the cash is stuck.

Black Box Ltd's cash cycle, the days between paying suppliers and getting paid by customers, was −10 days in FY26, up from −68 days in FY21. It spent ₹430 Cr on assets over the last 3 years. Customers take 67 days to pay, and stock sits for 53 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 ₹6,322 Cr, each day of that cycle ties up about ₹17.3 Cr, so roughly −₹173 Cr is tied up in the business at any time.

FY26: customers took 67 days to pay and stock sat for 53 days, about 1.7 months of sales sitting as stock, for a full cycle of −10 days, longer than FY21's −68.

The full loop: cash goes out to suppliers and production on day 0. Stock sits for 53 days. Customers pay about 67 days after that. Suppliers are paid at 129 days. Together that makes the −10-day cycle.

Spending on assets: ₹430 Cr over the last 3 years, against ₹343 Cr of depreciation (the yearly wear and tear on existing assets). So it is building a little beyond replacing what wears out. Work still in progress is ₹0.0 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.

Black Box Ltd's P/E is 50.2×, near the high end of its own history: higher than 86% of past readings. Its usual P/E (the middle reading) is 32.8×, over 8.4 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.

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 Jun 2026 add up to ₹12.99.
