What is changing at Diamond Power Infrastructure, from the latest results and calls: operating leverage on turnaround base, ehv cable introduction and order book ramp and india t&d capital spending supercycle tailwind.

• Operating Leverage on Turnaround Base. Revenue growing 54-75% on a year earlier is translating to 335-693% operating profit/profit growth, classic fixed-cost leverage on near-zero base. ⚠ estimate
• India T&D Capital spending Supercycle Tailwind. India T&D sector to receive ₹9 trillion capital spending through 2032; 10-15% cable demand yearly growth underpins DPIL's addressable market expansion. ⚠ estimate
• Retail URJA Brand Expansion. Retail sales grew 100% on the previous quarter in October to December 2025, nascent brand-pull strategy aiming for 7x customer base increase in 2 years, but track record is limited. ⚠ estimate

We check 16 kinds of change in every company, such as costs spread over more sales, higher-value products, new orders, new regions or falling debt, against its reported numbers and what management said on its calls. Only changes the numbers back are shown.

Company has an order book of over ₹3,300 crore, ensuring clear visibility for FY27; major orders include ₹1,349 Cr from Adani Energy Solutions and ₹748 Cr from Adani Green Energy.

• As of March 2026, the company boasts a robust order book exceeding ₹3,500 crore, underpinned by a staggering 733% on a year earlier surge in net profit during October to December 2025. ✓ fact

Our read after the latest results, written 17 May 2026.

Book value is -₹13.6/share; ₹610 Cr borrowings (Sep 2025); interest expense growing from ₹1 Cr (Mar25) to ₹11 Cr (Dec25), financial fragility persists despite operating turnaround.

The main risks

• Negative Net Worth and High Leverage: Book value is -₹13.6/share; ₹610 Cr borrowings (Sep 2025); interest expense growing from ₹1 Cr (Mar25) to ₹11 Cr (Dec25), financial fragility persists despite operating turnaround. ✓ fact
• Aluminium/Copper Price Volatility: Raw material is the primary cost driver; despite PV formula clauses, timing mismatches between procurement and billing can compress margins 8-12% on sharp spikes. ⚠ estimate
• Adani Group Customer Concentration: Adani Energy Solutions (₹1,349 Cr) + Adani Green Energy (₹748 Cr) = ~60% of the ₹3,300 Cr order book, any Adani capital spending slowdown or dispute flows directly to DPIL. ✓ fact
• Promoter Stake Reduction via OFS: Promoter stake declined from 90.6% (Jun 2024) to 84.0% (Dec 2025), with an OFS in June 2025, post-NCLT resolution monetization by the acquirer is a natural event but worth monitoring for further dilution. ✓ fact

When Diamond Power Infrastructure reports July to September 2026, these are the 4 checks that show whether the story is still on course. First: Q2 revenue and operating profit progression as monsoon disruption recedes; check whether the gradual ramp supports the full-year framework.

Diamond Power Infrastructure is on 4 of our India lists: Momentum stocks, Small & mid cap stocks, AI & data centre stocks and Power & green energy stocks.

Diamond Power Infrastructure Ltd earned ₹58.0 Cr of net profit in the Jun 2026 quarter, +262.5% on the same quarter a year earlier. That is the 4th quarter in a row of profit growth. Full-year FY26 profit was ₹158 Cr. Over 16 years profit has grown 6.0% a year on average. That is 8.4% 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 ₹16.0 Cr. 1 of the last 12 reported quarters were loss-making.

For the full year, FY26 profit was ₹158 Cr (+364.7% on the year before).

Why profit moved: revenue changed +128.5% 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 +552.1% and revenue +91.6%. Profit is growing faster than sales: fixed costs are spread over more sales, so each extra rupee of revenue adds more to profit.

FY26-Q2. Strong Q2: Revenue +75% YoY, PAT +593% YoY. QIP fundraising of ₹1,000 Cr approved (Board approval, Nov 2025). New aluminium rod mill commissioned (Sep 2025). ₹1,554 Cr order book as of Jun 2025 ramp to ₹3,300+ Cr by Q3 end, significant order intake in H2.

FY26-Q3. Breakout quarter: Revenue ₹474 Cr (+54% YoY), EBITDA ₹69.76 Cr (+335% YoY), PAT ₹49.72 Cr (+692% YoY). Gross margin 23.3%. Three drivers cited: EHV cable introduction, retail sales +100% QoQ, cost optimization in RM/packaging/logistics. HT Cable = 41% of sales, LT = 36%, Conductors = 23%.

Why-sources: our stock research file (17 May 2026) and the company’s own results for those quarters.

Diamond Power Infrastructure Ltd reported ₹690 Cr of revenue in the Jun 2026 quarter, +128.5% on the same quarter a year earlier. That is the 9th quarter in a row with growth on the year before. Over 16 years it has grown 5.1% a year on average. The last full year, FY26, came in at ₹1,910 Cr.

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

Why this happened. India's National Electricity Plan goals 500 GW non-fossil capacity by 2030 under RDSS/PM Gati Shakti, requiring massive transmission infrastructure. The T&D capex cycle that started FY22-23 drove sharp order book growth across the sector. Near-term (FY26) ordering slowed to 16 schemes from 45 in FY25 due to bandwidth constraints, but structural demand is intact. DPIL directly benefits via HTLS conductors, MV covered conductors, and EHV cable capability expansion. The company serves utilities in 16 states and is adding Adani's renewable energy projects as a major customer cluster.

The last four reported quarters add to ₹2,298 Cr.

FY26 revenue was ₹1,910 Cr, +71.3% on the year before.

Recent pace: the last four quarters grew +91.6% on average, against 5.1% 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 +92.6%, against +115.9% a year over the last 8 quarters (rolling over); profit over the last 12 months grew +467.6%, against +162.5% a year (accelerating).

FY26-Q2. Strong Q2: Revenue +75% YoY, PAT +593% YoY. QIP fundraising of ₹1,000 Cr approved (Board approval, Nov 2025). New aluminium rod mill commissioned (Sep 2025). ₹1,554 Cr order book as of Jun 2025 ramp to ₹3,300+ Cr by Q3 end, significant order intake in H2.

FY26-Q3. Breakout quarter: Revenue ₹474 Cr (+54% YoY), EBITDA ₹69.76 Cr (+335% YoY), PAT ₹49.72 Cr (+692% YoY). Gross margin 23.3%. Three drivers cited: EHV cable introduction, retail sales +100% QoQ, cost optimization in RM/packaging/logistics. HT Cable = 41% of sales, LT = 36%, Conductors = 23%.

Why-sources: our stock research file (17 May 2026) and the company’s own results for those quarters.

Diamond Power Infrastructure Ltd's operating margin was 11.0% in the Jun 2026 quarter, 1.0 percentage points higher than the same quarter a year ago. Across 13 years it has been between −57.0% and 14.0%. 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 this happened. Diamond Power's cost structure was reset in the NCLT resolution. Fixed overhead (interest, depreciation) was restructured, and the company restarted production on legacy capacity. As volumes recovered, every incremental rupee of revenue dropped disproportionately to profit. Q3 FY26 EBITDA growth of 335% YoY on 54% revenue growth is the clearest proof. The company executed a cost optimization program covering raw material consumption, packaging, and logistics simultaneously. This leverage is real but also means any demand softness would hit profits hard, it cuts both ways.

Why the margin moved: operating margin changed +0.9 percentage points on the year while gross margin changed −1.7 points. So the gain came mostly from the gross margin, which means input costs and prices charged.

FY26-Q2. Strong Q2: Revenue +75% YoY, PAT +593% YoY. QIP fundraising of ₹1,000 Cr approved (Board approval, Nov 2025). New aluminium rod mill commissioned (Sep 2025). ₹1,554 Cr order book as of Jun 2025 ramp to ₹3,300+ Cr by Q3 end, significant order intake in H2.

FY26-Q3. Breakout quarter: Revenue ₹474 Cr (+54% YoY), EBITDA ₹69.76 Cr (+335% YoY), PAT ₹49.72 Cr (+692% YoY). Gross margin 23.3%. Three drivers cited: EHV cable introduction, retail sales +100% QoQ, cost optimization in RM/packaging/logistics. HT Cable = 41% of sales, LT = 36%, Conductors = 23%.

Why-sources: our stock research file (17 May 2026) and the company’s own results for those quarters.

Over the last 3 years, 62% of Diamond Power Infrastructure Ltd's reported profit came in as cash from its operations, so most of the profit is real cash. In FY26 it brought in ₹36.0 Cr of operating cash against ₹158 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 ₹81.0 Cr of spending on assets, free cash was −₹45.0 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 62% of profit came in as cash: the cash cycle got 113 days shorter between FY15 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: no single use of cash stands out. The next section checks both the cash tied up in daily operations and the spending on assets.

Diamond Power Infrastructure Ltd's cash cycle, the days between paying suppliers and getting paid by customers, was 93 days in FY26, down from 206 days in FY15. It spent ₹154 Cr on assets over the last 3 years. Customers take 89 days to pay, and stock sits for 89 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 ₹1,910 Cr, each day of that cycle ties up about ₹5.2 Cr, so roughly ₹487 Cr is tied up in the business at any time.

FY26: customers took 89 days to pay and stock sat for 89 days, about 2.9 months of sales sitting as stock, for a full cycle of 93 days, shorter than FY15's 206.

The full loop: cash goes out to suppliers and production on day 0. Stock sits for 89 days. Customers pay about 89 days after that. Suppliers are paid at 85 days. Together that makes the 93-day cycle.

Spending on assets: ₹154 Cr over the last 3 years, against ₹145 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 ₹152 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.

Diamond Power Infrastructure Ltd's P/E is 117.8×, in the middle of its own history: higher than 40% of past readings. Its usual P/E (the middle reading) is 126.4×, over 2.3 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 ₹3.66.

Why the multiple is where it is: over the past year earnings per share moved +361.5% while the price moved +153.8%. Earnings did better than the price, which pulled the multiple down within its own range.

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

Diamond Power Infrastructure Ltd's business is turning around. Profit growth has swung from −24.4% at its low to +262.5%, rising from a low 5 quarters ago (from single-quarter figures). This is based on 8 quarters of 2 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.
