Diamond Power Infrastructure Ltd

Price story Before the numbers, the tape. A stock price moves through four repeating seasons: a flat base (stage 1), an advance (2), a top (3), a decline (4). Where the price sits in that cycle frames everything below.

Diamond Power Infrastructure Ltd trades at ₹355, in a confirmed uptrend and 22 weeks into that stage. That is +51.4% against its own 200-day average. It sits at 94% of a 52-week range of ₹120 to ₹369. On relative strength it has been ahead of the NIFTY 500 on a trailing-13-week view for 12 straight weeks.

Today the stock is in a confirmed uptrend — week 22 of stage 2, confirmed. At ₹355 it trades +51.4% versus its 200-day average and sits at 94% of its 52-week range (₹120–₹369).

Against the market, two honest reads. Cumulative: over the last 10.5 years the stock moved +14,137% while the NIFTY 500 moved +262% — ahead of the index over the full window. Recent form: on a trailing-13-week view the stock has been ahead for 12 straight weeks — the ribbon below is that same metric, week by week.

What would end the trend, mechanically: two Friday closes in a row below the 200-day line. That is the exit rule — no debates.

Our read, 17 May 2026. NCLT-resolved turnaround now generating real cash from a ₹3,500 Cr order book — but at PE 98x on a negative book value, the re-rating is already pricing in flawless execution.

What is proven. NCLT-resolved turnaround now generating real cash from a ₹3,500 Cr order book — but at PE 98x on a negative book value, the re-rating is already pricing in flawless execution.

What is not proven yet. 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 test written in advance. Negative Net Worth and High Leverage — Negative Net Worth and High Leverage Three consecutive quarters of net worth turning positive AND D/E <0.5x would downgrade this risk to MEDIUM. by the next result.

The test written in advance. Aluminium/Copper Price Volatility — Aluminium/Copper Price Volatility Six consecutive quarters of OPM >12% despite commodity swings would confirm the PV clause protection is effective. by the next result.

What the company does. Q3 FY26: Revenue +54% YoY to ₹474 Cr, PAT +692% YoY to ₹49.7 Cr, EBITDA +335% YoY — operating leverage from a near-zero base now clear in the numbers. Order book >₹3,500 Cr (Mar 2026), anchored by Adani Energy Solutions ₹1,349 Cr and Adani Green Energy ₹748 Cr, gives 9M+ revenue visibility at current run-rates. Structural risk: negative net worth (-₹13.6/share book value), ₹610 Cr borrowings, PE 98x — a cyclical cable company priced as a secular compounder; execution slippage or commodity spike would compress multiples sharply.

Lever 1 · Operating leverage — BUILDING. Revenue growing 54-75% YoY is translating to 335-693% EBITDA/PAT growth — classic fixed-cost leverage on near-zero base. What proves it keeps working: Operating Leverage on Turnaround Base. It stops working if Three consecutive quarters of net worth turning positive AND D/E <0.5x would downgrade this risk to MEDIUM.

Lever 2 · Value-added mix — BUILDING. EHV cable entry (66 kV GETCO order, utility-grade products) combined with ₹3,500 Cr order book from Adani, L&T — product mix shifting toward higher-margin segments. What proves it keeps working: EHV Cable Introduction and Order Book Ramp. It stops working if Three consecutive quarters of net worth turning positive AND D/E <0.5x would downgrade this risk to MEDIUM.

Lever 10 · New geographies — BUILDING. India T&D sector to receive ₹9 trillion capex through 2032; 10-15% cable demand CAGR underpins DPIL's addressable market expansion. What proves it keeps working: India T&D Capex Supercycle Tailwind. It stops working if Three consecutive quarters of net worth turning positive AND D/E <0.5x would downgrade this risk to MEDIUM.

Lever 7 · Consolidation — BUILDING. Retail sales grew 100% QoQ in Q3 FY26 — nascent brand-pull strategy targeting 7x customer base increase in 2 years, but track record is limited. What proves it keeps working: Retail URJA Brand Expansion. It stops working if Three consecutive quarters of net worth turning positive AND D/E <0.5x would downgrade this risk to MEDIUM.

Revenue Revenue is the top line: everything the company billed its customers in the period.

Diamond Power Infrastructure Ltd reported ₹690 Cr of revenue in the Jun 26 quarter, +128.5% year on year. That is the 9th straight quarter of year-on-year growth. Over 16 years it has compounded at 5.1% a year. The last full year, FY26, came in at ₹1,910 Cr. The last four reported quarters add to ₹2,298 Cr.

Why this happened. India's National Electricity Plan targets 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.

FY26 revenue came in at ₹1,910 Cr (+71.3% on the year), capping 16 years at 5.1% compound. The latest quarter (Jun 26) printed ₹690 Cr, +128.5% year on year — the 9th consecutive quarter of year-over-year growth.

Pace check: the last four quarters averaged +91.6% growth against the decade's 5.1% — the current year is running faster than its own long-run rate.

Acceleration check: trailing-twelve-month revenue grew +92.6% over the last 4 quarters against +115.9%/yr over the last 8 — rolling over; TTM profit +467.6% vs +162.5%/yr — 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.

Operating margin Operating margin is what is left of every ₹100 of sales after running the business, before interest and tax. It is the cleanest read on pricing power and cost control.

Diamond Power Infrastructure Ltd's operating margin is 11.0% in the Jun 26 quarter, +1.0 percentage points against the same quarter a year ago. Across 13 fiscal years the operating margin has ranged −57.0% to 14.0%. The current quarter sits inside that band.

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.

The latest quarter's operating margin is 11.0%, +1.0 pp against the same quarter a year ago. Across 13 fiscal years the operating margin has ranged −57.0%–14.0%.

Why the margin moved: operating margin went +0.9 pp year on year while gross margin went −1.7 pp — the gain came mostly from the gross line: input costs and pricing.

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%.

Net profit Net profit is what survives every cost, interest and tax — the number EPS, dividends and book value all grow from.

Diamond Power Infrastructure Ltd earned ₹58.0 Cr of net profit in the Jun 26 quarter, +262.5% year on year. It is the 4th consecutive quarter of growth. Full-year FY26 profit was ₹143 Cr. The 16-year compound rate is 5.4%. That is 8.4% of the quarter's revenue. The same quarter a year earlier earned ₹16.0 Cr.

Jun 26 profit was ₹58.0 Cr, +262.5% year on year — the 4th consecutive quarter of growth. On the full year, FY26 printed ₹143 Cr (+320.6%), and the 16-year compound rate is 5.4%.

Why profit moved: revenue contributed +128.5% and the margin +1.0 pp — the quarter was revenue-led, with the margin roughly flat.

Pace comparison, last four quarters: profit +552.1% vs revenue +91.6%. Profit is growing faster than sales — fixed costs are being spread over a bigger base, and each extra rupee of revenue drops more to the bottom line.

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.

Cash flow — the router The P&L says what was earned; the cash-flow statement says what actually arrived. Operating cash flow (CFO) against profit is the cleanest lie detector in the accounts.

Over the last 3 fiscal years 7% of Diamond Power Infrastructure Ltd's reported profit arrived as operating cash — a gap worth watching. In FY26 that was ₹−80.0 Cr of operating cash against ₹143 Cr of profit. After ₹81.0 Cr of capital spending, ₹−161 Cr was left as free cash.

FY26: operating cash of ₹−80.0 Cr against reported profit of ₹143 Cr, leaving free cash of ₹−161 Cr after ₹81.0 Cr of capital spending. Across the last 3 fiscal years the conversion rate is 7% of profit.

Cash-flow readings here are annual — that is the resolution our series carries, so this section moves once a year.

🚨 Why conversion sits at 7%: the cash cycle tightened 113 days between FY15 and FY26 — cash that used to wait in the cycle now reaches the bank sooner. Less than 70% of profit arriving as cash is the thing to watch on this page.

Router verdict: no single sink dominates — the next section checks both the working-capital cycle and the capital spending.

Where the cash goes Working capital is the cash tied up between paying suppliers and getting paid: debtor days (customers owe), inventory days (stock waits), and the cash conversion cycle (the whole loop, in days of sales).

Diamond Power Infrastructure Ltd's cash conversion cycle runs 93 days in FY26, down from 206 days in FY15. Capital spending ran ₹154 Cr over the last 3 years. At FY26 sales of ₹1,910 Cr each day of that cycle holds about ₹5.2 Cr, so roughly ₹487 Cr sits inside the business at any moment.

FY26: debtors at 89 days, inventory at 88 days — roughly 2.9 months of stock waiting to sell; that is where the cash sits while it waits — for a full cycle of 93 days, tighter than FY15's 206.

The full loop: cash goes out to suppliers and production on day 0; stock waits 88 days to sell; customers pay about 89 days after that; and suppliers themselves are paid at 84 days — netting out to the 93-day cycle.

In money terms: at FY26 sales of ₹1,910 Cr, each day of the cycle holds about ₹5.2 Cr — so the 93-day loop keeps roughly ₹487 Cr sitting inside the business at any moment.

On the investment side: capital spending of ₹154 Cr over the last 3 fiscal years against ₹145 Cr of depreciation — building somewhat ahead of wear-and-tear. Capital work-in-progress stands at ₹152 Cr (FY26) — capacity paid for but not yet earning.

The synthesis: neither the cycle nor the build-out is hoarding the cash — the machine is reasonably clean.

Return on capital Return on capital employed (ROCE) is the profit the whole business earns on all the money in it — equity and debt together. It is the single best test of whether growth creates value or just size.

Diamond Power Infrastructure Ltd earns a ROCE of 26% in FY26. That is up from a trough of −29% in FY17. Return on invested capital clears the cost of that capital by −0.4 percentage points, so growth here is not yet paying for the capital it uses. The wiring behind it is 7.5% net margin on 0.79× asset turns.

FY26 ROCE is 26%, recovered from a FY17 trough of −29% — the full ladder below shows the fall and the climb, undoctored.

🚨 Why the return is what it is — the wiring (FY26): 7.5% net margin × 0.79× asset turns × −3.98× balance-sheet leverage ≈ −23.6% on equity. Margin does its share; leverage is modest — this is an earned return, not a borrowed one.

The capstone test — ROIC − WACC: 11.6% − 12.0% = a −0.4 pp spread. The 12.0% is a standing assumption for the cost of capital in India, not a per-stock estimate — read the sign and the size of the spread, not the decimals. Negative — growth at these returns destroys value until the returns recover.

Debt Debt-to-equity says how much of the business is funded by borrowings. Low is the safe corner; the trend matters as much as the level.

Diamond Power Infrastructure Ltd's net worth is negative — it owes more than it owns — so a debt-to-equity ratio is not meaningful here. On the annual view that ratio went from −3.29 in FY22 to −4.20 in FY26. The returns elsewhere on this page are therefore earned rather than borrowed.

Mar 26: total debt of ₹2,537 Cr against shareholder equity of ₹−604 Cr — a debt-to-equity of −4.20. On the annual view, debt-to-equity went from −3.29 (FY22) to −4.20 (FY26). The returns on this page are earned, not borrowed.

Ownership Who owns the stock, quarter by quarter: promoters (the controlling owners), foreign and domestic institutions, and the public. Steady accumulation by people close to the numbers is a signal; a quiet register is also an answer.

Promoters cut 16.5 points of Diamond Power Infrastructure Ltd over 8 quarters, the biggest move on the register. That takes promoters to 74.0% of the company. Domestic institutions moved +10.9 points over the same window, to 10.9%. The register is read on the four disclosed classes only; nothing is inferred between filings.

The register over the last two years — Promoters: −16.5 points over 8 quarters to 74.0%; Domestic institutions: +10.9 points over 8 quarters to 10.9%; Foreign institutions: +4.5 points over 8 quarters to 4.6%.

🚨 Why the register moved: promoters drove it (−16.5 points), absorbed on the other side by domestic institutions (+10.9 points) — distribution into the market’s bid.

Safety line The Z-score estimates how far a company sits from balance-sheet distress — above roughly 3 is safe, below roughly 1.8 is the danger zone. It was built for manufacturers, so it is not applied to banks and lenders.

Diamond Power Infrastructure Ltd: the Z-score is not available for this stock, so we say so rather than invent one. It is a distance-to-distress estimate from the balance sheet, not a forecast of failure. The debt, cash-flow and return sections above carry the balance-sheet evidence this page does hold, and each of them states its own reporting date.

The safety line in one sentence: the Z-score is not available for this stock, so we say so rather than invent one.

Valuation P/E is the price of ₹1 of annual profit: how many rupees the market pays for each rupee the company earns in a year.

Diamond Power Infrastructure Ltd trades at 104.0× P/E, near the bottom of its own range — cheaper only 32% of the time. Its long-run median P/E is 127.3×, measured across 2.2 years of weekly readings. This places the multiple against the stock’s own record, and says nothing about what the business is worth.

Today's P/E of 104.0× is near the bottom of its own range — cheaper only 32% of the time, against a long-run median of 127.3× measured over 2.2 years of weekly readings. This is a comparison against the stock's own history — not a claim about what it is worth.

Why the multiple sits where it does: over the past year annual EPS moved +318.5% against a +135.1% price move — earnings outran the price, pushing the multiple DOWN its own range.

Put together: the multiple is low against its own past, so the story rests on the earnings line underneath it, not the multiple.

What the price assumes This reading works the multiple backwards. It asks one question: what yearly rate of profit growth is a buyer at the market price already paying for? The number is the growth rate that makes eleven years of profit — six years growing, then five fading — add up to that day's market price, once each year is discounted at 11% a year.

Solved at its 29 June 2026 price, Diamond Power Infrastructure Ltd was paying for profit growth of about 31.2% a year. Profit itself has compounded 5.4% a year over the past 16 years. Today the market pays 104.0× P/E, the 32nd percentile of its own 2-year range.

What the two numbers say together. The multiple is low against its own past, and the growth the price is paying for is far above what this company has actually delivered. A multiple that looks low because earnings fell is not the same thing as a low bar to clear.

How to hold this number: it is a reading of one day's price, taken on 29 June 2026, not a running figure — every other number on this page, the multiple included, is read off the live quote as of 28 September 2026. A higher price is paying for more growth and a lower price for less, so it moves whenever the price does, and this page does not restate it between measurements.

Stage: Turning around Every business sits somewhere on a fundamental arc, and this page names the spot before anything else. The last twelve quarters of revenue, profit and EPS growth — plus the return the business earns on its capital — are read as curves: Deteriorating (the curves are falling), Turning around (a trough has just formed and the last few quarters lift off it), Improving (the climb off the trough is sustained), Consistent (steadily positive with healthy returns), Topping out (still high but decelerating from the peak). When the curves genuinely disagree the read is Mixed; too little history is No read. CAGR (compound annual growth rate) is the smooth yearly pace that turns the starting value into the latest one — the fairest way to compare growth across different time spans. Read the columns together: if the 1-year number towers over the 10-year, recent growth is running hotter than the long-run trend. A dash means that window is not held, or the base year was a loss (where a growth rate is not meaningful).

Diamond Power Infrastructure Ltd reads as turning around on its fundamental arc. Turning around — profit growth swung from −24.4% at the trough to +262.5% off a 5-quarter-old trough (single-quarter readings). The read is built from 8 quarters across 2 curves, on partial evidence.

Why it matters: growth inflections are where re-ratings start — the curves say a turn is forming, so the question becomes whether the next quarters confirm it.

The return-on-capital curve is not shown — net worth is negative, so a return on capital is not a meaningful number in any basis. This is a distressed balance sheet, and the stage is read from the growth curves alone.

One or more growth curves carry a base-effect spike — a large year-on-year move off a near-zero or loss-making comparable quarter. Those spikes are capped before the classifier reads the trajectory, and shown pinned on the chart, so a single distorted quarter does not drive the stage call.

A partial read: at least one curve is short, or the returns curve is not the computed quarterly series — hold the stage word a little more loosely.
