Tamil Nadu Petro Products 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.

Tamil Nadu Petro Products Ltd trades at ₹129, in a confirmed uptrend and 5 weeks into that stage. That is +29.2% against its own 200-day average. It sits at 93% of a 52-week range of ₹81 to ₹133. On relative strength it has been ahead of the NIFTY 500 on a trailing-13-week view for 18 straight weeks.

Today the stock is in a confirmed uptrend — week 5 of stage 2, confirmed. At ₹129 it trades +29.2% versus its 200-day average and sits at 93% of its 52-week range (₹81–₹133).

Against the market, two honest reads. Cumulative: over the last 10.5 years the stock moved +452% while the NIFTY 500 moved +267% — ahead of the index over the full window. Recent form: on a trailing-13-week view the stock has been ahead for 18 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.

Tamil Nadu Petro Products Ltd's story is not scored yet against the markers our research file set on 22 August 2026. Where it sits in its own cycle: MID_CONTRACTION. Our fortnightly research layers last read it on 22 August 2026.

Our read, 22 August 2026. TNPETRO presents an optical deep-value setup trading at 7.6x trailing PE with expanded capacity following ₹805 Cr in five-year capex, but faces margin mean-reversion risk from peak 15.0% OPM alongside working capital bloat.

From the numbers. The cycle matrix assigns a STRONG_OPPORTUNITY matrix label based on contracting valuation multiples and improving momentum off cyclical troughs. However, the deterministic cycle normalized engine identifies a peak…

From the price. Price stage 2, week 5 — above its 200-day line, relative strength rising.

From the research. TNPETRO presents an optical deep-value setup trading at 7.6x trailing PE with expanded capacity following ₹805 Cr in five-year capex, but faces margin mean-reversion risk from peak 15.0% OPM alongside working capital…

🚨 Where they disagree. Weekly live PE is 9.4x (67th percentile, 1.34x of 7.0x median) with contracting trend. Trailing curve PE of 7.6x sits near the 59th percentile of 10-year history. However, normalized to mid-cycle OPM of 7.6% (vs trailing 15.5%), the normalized PE rises to 12.1x (77th percentile), signaling that current earnings are cyclically elevated and susceptible to mean-reversion.

What is proven. TNPETRO presents an optical deep-value setup trading at 7.6x trailing PE with expanded capacity following ₹805 Cr in five-year capex, but faces margin mean-reversion risk from peak 15.0% OPM alongside working capital bloat.

What is not proven yet. Quarterly operating margin dropping below 6.0% combined with working capital inventory days failing to reduce below 90 days over the next two quarters, indicating that peak margins have collapsed while cash remains trapped in unliquidated inventory.

🚨 What would change our mind. Quarterly operating margin dropping below 6.0% combined with working capital inventory days failing to reduce below 90 days over the next two quarters, indicating that peak margins have collapsed while cash remains trapped in unliquidated inventory.

🚨 Layer 1 read, 22 August 2026 — DROP. The shrinking-revenue alarm is false — one quarter was a shutdown to commission a new Rs 805 crore plant. On the screen this looks like a company whose sales are falling, and the pipeline flags that as a reason to reject. It is not true. Sales fell for one quarter only — Rs 124 crore in March against a normal Rs 450 crore — and the balance sheet shows exactly why: during that year Rs 336 crore of half-built plant moved onto the books as finished, working assets (work-in-progress fell from Rs 452 crore to Rs 116 crore while fixed assets rose from Rs 285 crore to Rs 852 crore) and the depreciation charge then doubled. That is a shutdown to connect a new plant, not lost customers. The unresolved question is the quarter after: sales of Rs 780 crore look spectacular, but the two quarters TOGETHER…

What would change Layer 1’s mind. Q2 FY27 sales at or above Rs 500 crore with the operating margin holding at or above 8% — that single print separates a genuine capacity ramp from a one-quarter inventory clear-out, and it would take this to P1 given how early the price still is. The opposite print — sales falling back toward Rs 450-500 crore with inventory days still above 100 and operating cash flow still negative — confirms the destock reading, and combined with a margin below 6% it becomes a drop.

The test written in advance. Quarterly operating margin dropping below 6.0% combined with working capital inventory days failing to reduce below 90 days over the next two quarters, indicating that peak margins have collapsed while cash remains trapped in unliquidated inventory. — the thesis as written as stated by the next result.

The test written in advance. Peak Margin Mean-Reversion (Cycle Normalized Value Trap) — Peak Margin Mean-Reversion (Cycle Normalized Value Trap) Quarterly OPM declining below 8.0% in subsequent reporting periods. by the next result.

The test written in advance. Working Capital Bloat and Cash Conversion Deficit — Working Capital Bloat and Cash Conversion Deficit FY27 semi-annual balance sheet showing inventory days remaining above 100 days. by the next result.

What the company does. Optically discounted multiple of 7.6x trailing PE masks cyclically elevated operating margins of 15.0% (93rd percentile of historical range vs 7.6% mid-cycle norm). Five-year capex deployment of ₹805 Cr expanded balance sheet borrowings to ₹465 Cr and stretched FY26 cash conversion cycle to 116 days. Turnaround durability hinges on converting ₹223 Cr in working capital buildup into operating cash flow before product spreads compress.

🚨 What the surface reading misses. The surface reading is: Trading near book value (1.02x P/B) with a market cap of ₹1037 Cr suggests valuation support and limited downside risk. The research reads it further: Book value of ₹113 per share is backed heavily by recent capital expenditure additions (₹805 Cr 5-year capex), which elevates tangible asset backing but also debt (₹465 Cr), leaving returns on capital sensitive to commodity margin spreads.

🚨 What the surface reading misses. The surface reading is: Trailing PE of 7.6x in the 59th percentile appears moderate and inexpensive relative to broad market chemical multiples. The research reads it further: The trailing multiple is depressed by peak cyclical earnings; trailing EPS of ₹15.82 reflects 15.0% operating margin compared to historical mid-cycle normal of 7.6%.

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

Tamil Nadu Petro Products Ltd reported ₹780 Cr of revenue in the Jun 26 quarter, +68.5% year on year. Over 10 years it has compounded at 7.7% a year. The last full year, FY26, came in at ₹1,466 Cr. The last four reported quarters add to ₹1,782 Cr.

FY26 revenue came in at ₹1,466 Cr (−19.8% on the year), capping 10 years at 7.7% compound. The latest quarter (Jun 26) printed ₹780 Cr, +68.5% year on year.

Pace check: the last four quarters averaged −2.8% growth against the decade's 7.7% — the current year is running slower than its own long-run rate.

Acceleration check: trailing-twelve-month revenue grew −2.5% over the last 4 quarters against +3.0%/yr over the last 8 — rolling over; TTM profit +79.7% vs +68.5%/yr — accelerating.

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.

Tamil Nadu Petro Products Ltd's operating margin is 15.0% in the Jun 26 quarter, +5.0 percentage points against the same quarter a year ago. Across 13 fiscal years the operating margin has ranged −2.8% to 15.0%. The current quarter sits inside that band.

Why this happened. Favorable price differentials between raw materials (kerosene, benzene) and finished products (LAB, caustic soda) lifted OPM from 1.6% in Q2 FY25 to 10.0% in Q1 FY26 and 15.0% in Q1 FY27. This spread expansion drove Q1 FY27 net profit to ₹80 Cr (EPS ₹8.90), delivering 128.6% YoY profit growth.

The latest quarter's operating margin is 15.0%, +5.0 pp against the same quarter a year ago. Across 13 fiscal years the operating margin has ranged −2.8%–15.0%.

Why the margin moved: operating margin went +5.2 pp year on year while gross margin went +0.2 pp — the gain came mostly below the gross line: operating leverage, with costs spread over a bigger revenue base.

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

Tamil Nadu Petro Products Ltd earned ₹80.0 Cr of net profit in the Jun 26 quarter, +128.6% year on year. Full-year FY26 profit was ₹97.0 Cr. The 10-year compound rate is 10.1%. That is 10.3% of the quarter's revenue. The same quarter a year earlier earned ₹35.0 Cr.

Jun 26 profit was ₹80.0 Cr, +128.6% year on year. On the full year, FY26 printed ₹97.0 Cr (+67.2%), and the 10-year compound rate is 10.1%.

Why profit moved: revenue contributed +68.5% and the margin +5.0 pp — the quarter was margin-led: most of the profit growth came from keeping more of each sale.

Pace comparison, last four quarters: profit +176.2% vs revenue −2.8%. 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.

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 131% of Tamil Nadu Petro Products Ltd's reported profit arrived as operating cash — the cash follows the profit. In FY26 that was ₹−100 Cr of operating cash against ₹97.0 Cr of profit. After ₹257 Cr of capital spending, ₹−357 Cr was left as free cash.

Why this happened. FY26 operating cash flow was negative at -₹100 Cr primarily due to a working capital absorption of ₹223 Cr, with inventory days jumping to 132 days from 34 days in FY25. The Q1 FY27 revenue surge of ₹780 Cr indicates active inventory dispatch, which should reverse working capital lockups and generate positive operating cash flow to service debt.

FY26: operating cash of ₹−100 Cr against reported profit of ₹97.0 Cr, leaving free cash of ₹−357 Cr after ₹257 Cr of capital spending. Across the last 3 fiscal years the conversion rate is 131% 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 131%: the cash cycle stretched 54 days between FY21 and FY26 — more of each rupee of profit waits inside the cycle before arriving.

Router verdict: the bigger cash user is investment — capital spending ran 9.4× depreciation over three years, so the next section's job is to check what that build-out is buying.

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).

Tamil Nadu Petro Products Ltd's cash conversion cycle runs 109 days in FY26, up from 55 days in FY21. Capital spending ran ₹692 Cr over the last 3 years. At FY26 sales of ₹1,466 Cr each day of that cycle holds about ₹4.0 Cr, so roughly ₹438 Cr sits inside the business at any moment.

Why this happened. TNPETRO has deployed ₹805 Cr in cumulative capex between FY22 and FY26, including ₹385 Cr in FY25 and ₹257 Cr in FY26, modernizing and expanding its Linear Alkyl Benzene (LAB) and chlor-alkali facilities. As new capacity ramps up, higher asset turnover has the potential to generate operating leverage on fixed production costs.

FY26: debtors at 7 days, inventory at 132 days — roughly 4.3 months of stock waiting to sell; that is where the cash sits while it waits — for a full cycle of 109 days, looser than FY21's 55.

The full loop: cash goes out to suppliers and production on day 0; stock waits 132 days to sell; customers pay about 7 days after that; and suppliers themselves are paid at 30 days — netting out to the 109-day cycle.

In money terms: at FY26 sales of ₹1,466 Cr, each day of the cycle holds about ₹4.0 Cr — so the 109-day loop keeps roughly ₹438 Cr sitting inside the business at any moment.

On the investment side: capital spending of ₹692 Cr over the last 3 fiscal years against ₹74.0 Cr of depreciation — the company is building well ahead of wear-and-tear. Capital work-in-progress stands at ₹116 Cr (FY26) — capacity paid for but not yet earning.

The synthesis: the cash is going into capacity, not disappearing into the cycle — the question becomes whether the new capacity earns.

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.⚠ unverified

Tamil Nadu Petro Products Ltd earns a ROCE of 11% in FY26. That is up from a trough of −8% in FY15. Return on invested capital clears the cost of that capital by −4.6 percentage points, so growth here is not yet paying for the capital it uses. The wiring behind it is 6.6% net margin on 0.86× asset turns.

FY26 ROCE is 11%, recovered from a FY15 trough of −8% — the full ladder below shows the fall and the climb, undoctored.

🚨 Why the return is what it is — the wiring (FY26): 6.6% net margin × 0.86× asset turns × 1.67× balance-sheet leverage ≈ 9.5% on equity. Margin does its share; leverage is a meaningful part of the equation.

The capstone test — ROIC − WACC: 7.4% − 12.0% = a −4.6 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.⚠ unverified

Tamil Nadu Petro Products Ltd carries total debt of ₹465 Cr against shareholder equity of ₹1,018 Cr as of Mar 26, a debt-to-equity of 0.46. On the annual view that ratio went from 0.07 in FY22 to 0.46 in FY26. Read the returns elsewhere on this page with that leverage in mind.

Mar 26: total debt of ₹465 Cr against shareholder equity of ₹1,018 Cr — a debt-to-equity of 0.46. On the annual view, debt-to-equity went from 0.07 (FY22) to 0.46 (FY26). Read the returns on this page with that leverage in mind.

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.

Foreign institutions added 4.9 points of Tamil Nadu Petro Products Ltd over 8 quarters, the biggest move on the register. That takes foreign institutions to 11.1% of the company. Promoters moved +0.0 points over the same window, to 34.5%. The register is read on the four disclosed classes only; nothing is inferred between filings.

Why this happened. FII ownership expanded by 341 bps over three quarters to reach 8.76% in Sep 2025, while promoter holding remained anchored at 34.54%. Trading at 1.02x Price-to-Book with book value of ₹113 per share, the asset base provides downside valuation support at current market prices.

The register over the last two years — Foreign institutions: +4.9 points over 8 quarters to 11.1%; Promoters: +0.0 points over 8 quarters to 34.5%; Domestic institutions: +0.0 points over 8 quarters to 0.0%.

Why the register moved: foreign institutions drove it (+4.9 points) — steady accumulation by institutions reading the same numbers this page reads.

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.

Tamil Nadu Petro Products 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.

Tamil Nadu Petro Products Ltd trades at 8.5× P/E, mid-range by its own standards (63rd percentile). Its long-run median P/E is 6.9×, measured across 8.1 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 8.5× is mid-range by its own standards (63rd percentile), against a long-run median of 6.9× measured over 8.1 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 +66.9% against a +28.5% price move — earnings outran the price, pushing the multiple DOWN its own range.

The price move, decomposed: over 5y, of the +2.6%/yr price move, ~−2.2%/yr came from earnings growth and ~+4.8 pp from the multiple (expanding). The split is the honest approximate (price return minus earnings growth); it makes the rally itself visible instead of hiding it behind the percentile.

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

A quarterly PEG curve, which only the second data source carries, is not drawn on this page: its two data sources do not share enough overlapping reported history to be compared. A figure nobody could check is not used to price growth — the gap is a decision, not missing data.

Stage: Mixed 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).

Tamil Nadu Petro Products Ltd reads as mixed on its fundamental arc. Mixed — no clean majority across the growth curves, ROCE holding at 11.0% — the per-curve reads carry the story. The read is built from 8 quarters across 4 curves, on partial evidence.

Why it matters: when the curves disagree, the per-curve reads above matter more than any single verdict.

Return readings here are annual, not quarterly — read as level and direction only; they can confirm the growth curves but never drive the stage on their own.

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.
