Tenneco Clean Air India 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.

Tenneco Clean Air India Ltd trades at ₹538, in a confirmed uptrend and 31 weeks into that stage. That is −2.1% against its own 200-day average. It sits at 39% of a 52-week range of ₹473 to ₹640. On relative strength it is currently behind the NIFTY 500 on a trailing-13-week view (9 weeks and counting).

Today the stock is in a confirmed uptrend — week 31 of stage 2, confirmed. At ₹538 it trades −2.1% versus its 200-day average and sits at 39% of its 52-week range (₹473–₹640).

Against the market, two honest reads. Cumulative: over the last 8 months the stock moved +13% while the NIFTY 500 moved −2% — ahead of the index over the full window. Recent form: on a trailing-13-week view the stock is currently behind (9 weeks and counting; last ahead the week of 2026-06-24) — 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.

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.

Tenneco Clean Air India Ltd trades at 35.0× P/E, near the bottom of its own range — cheaper only 33% of the time. Its long-run median P/E is 36.3×, measured across 0.7 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 35.0× is near the bottom of its own range — cheaper only 33% of the time, against a long-run median of 36.3× measured over 0.7 years of weekly readings. This is a comparison against the stock's own history — not a claim about what it is worth.

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

Stage: No read 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).

Tenneco Clean Air India Ltd reads as no read on its fundamental arc. Under eight usable quarters on the growth trio — not enough history for an honest trajectory read. The read is built from 5 quarters across 1 curve, on partial evidence.

Why it matters: with too little history, an honest page says so instead of guessing a trajectory.

Fewer than eight usable quarters on the growth curves — this page will not guess a trajectory from a stub of history.

4-Factor Sector Score

58.3/100 — rank 1 of 2 in Auto Ancillaries - Others · 70% evidence confidence

Tenneco Clean Air India Ltd scores 58.3 out of 100 against the 2 companies it is compared with in Auto Ancillaries - Others, ranking 1. Balanced evidence: keep at normal research priority and require another comparable period before raising conviction.

The four contributions add to the total exactly: 19.1 + 19.9 + 9.3 + 10 = 58.3. This is the SAME number shown on the sector comparison — it is computed once, for the whole peer set, and read here.

What would change it: The read weakens if profit growth turns negative or margin improvement reverses while sector-relative strength deteriorates.

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

Tenneco Clean Air India Ltd reported ₹1,545 Cr of revenue in the Jun 26 quarter, +20.1% year on year. That is the 5th straight quarter of year-on-year growth. Over 3 years it has compounded at 3.8% a year. The last full year, FY26, came in at ₹5,404 Cr. The last four reported quarters add to ₹5,663 Cr.

FY26 revenue came in at ₹5,404 Cr (+10.5% on the year), capping 3 years at 3.8% compound. The latest quarter (Jun 26) printed ₹1,545 Cr, +20.1% year on year — the 5th consecutive quarter of year-over-year growth.

Pace check: the last four quarters averaged +15.2% growth against the decade's 3.8% — the current year is running faster than its own long-run rate.

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.

Tenneco Clean Air India Ltd's operating margin is 16.0% in the Jun 26 quarter, −2.0 percentage points against the same quarter a year ago. Across 4 fiscal years the operating margin has ranged 11.0% to 17.0%. The current quarter sits inside that band.

The latest quarter's operating margin is 16.0%, −2.0 pp against the same quarter a year ago. Across 4 fiscal years the operating margin has ranged 11.0%–17.0%.

🚨 Why the margin moved: operating margin went −1.8 pp year on year while gross margin went −1.5 pp — the loss came mostly from the gross line: input costs and pricing.

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

Tenneco Clean Air India Ltd earned ₹165 Cr of net profit in the Jun 26 quarter, −1.8% year on year. Full-year FY26 profit was ₹604 Cr. The 3-year compound rate is 16.6%. That is 10.7% of the quarter's revenue. The same quarter a year earlier earned ₹168 Cr.

Jun 26 profit was ₹165 Cr, −1.8% year on year. On the full year, FY26 printed ₹604 Cr (+9.2%), and the 3-year compound rate is 16.6%.

🚨 Why profit moved: revenue contributed +20.1% and the margin −2.0 pp — the quarter was revenue-led despite a thinner margin.

Pace comparison, last four quarters: profit +5.7% vs revenue +15.2%. Profit is growing slower than sales — costs are eating the growth before it reaches 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 157% of Tenneco Clean Air India Ltd's reported profit arrived as operating cash — the cash follows the profit. In FY26 that was ₹1,429 Cr of operating cash against ₹604 Cr of profit. After ₹135 Cr of capital spending, ₹1,294 Cr was left as free cash.

FY26: operating cash of ₹1,429 Cr against reported profit of ₹604 Cr, leaving free cash of ₹1,294 Cr after ₹135 Cr of capital spending. Across the last 3 fiscal years the conversion rate is 157% 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 157%: the cash cycle tightened 17 days between FY23 and FY26 — cash that used to wait in the cycle now reaches the bank sooner.

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).

Tenneco Clean Air India Ltd's cash conversion cycle runs −33 days in FY26, down from −16 days in FY23. Capital spending ran ₹306 Cr over the last 3 years. At FY26 sales of ₹5,404 Cr each day of that cycle holds about ₹14.8 Cr, so roughly ₹−489 Cr sits inside the business at any moment.

FY26: debtors at 43 days, inventory at 35 days — roughly 1.2 months of stock waiting to sell; that is where the cash sits while it waits — for a full cycle of −33 days, tighter than FY23's −16.

The full loop: cash goes out to suppliers and production on day 0; stock waits 35 days to sell; customers pay about 43 days after that; and suppliers themselves are paid at 111 days — netting out to the −33-day cycle.

In money terms: at FY26 sales of ₹5,404 Cr, each day of the cycle holds about ₹14.8 Cr — so the −33-day loop keeps roughly ₹−489 Cr sitting inside the business at any moment.

On the investment side: capital spending of ₹306 Cr over the last 3 fiscal years against ₹315 Cr of depreciation — spending at or below maintenance level. Capital work-in-progress stands at ₹58.0 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.

Tenneco Clean Air India Ltd earns a ROCE of 61% in FY26. That is up from a trough of 52% in FY24. Return on invested capital clears the cost of that capital by +79.1 percentage points, so growth here adds value rather than only size. The wiring behind it is 11.2% net margin on 2.13× asset turns.

FY26 ROCE is 61%, recovered from a FY24 trough of 52% — the full ladder below shows the fall and the climb, undoctored.

Why the return is what it is — the wiring (FY26): 11.2% net margin × 2.13× asset turns × 2.12× balance-sheet leverage ≈ 50.6% on equity. Margin does its share; leverage is a meaningful part of the equation.

The capstone test — ROIC − WACC: 91.1% − 12.0% = a +79.1 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. A spread this wide means every rupee reinvested creates more than a rupee of value — the engine compounds.

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.

Tenneco Clean Air India Ltd carries total debt of ₹51.0 Cr against shareholder equity of ₹1,201 Cr as of Mar 26, a debt-to-equity of 0.04 — effectively unlevered. On the annual view that ratio went from 0.01 in FY25 to 0.04 in FY26. The returns elsewhere on this page are therefore earned rather than borrowed.

Mar 26: total debt of ₹51.0 Cr against shareholder equity of ₹1,201 Cr — a debt-to-equity of 0.04. On the annual view, debt-to-equity went from 0.01 (FY25) to 0.04 (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.

No holder of Tenneco Clean Air India Ltd moved a full percentage point over the last two years — the register is quiet. The register is read on the four disclosed classes only; nothing is inferred between filings.

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.

Tenneco Clean Air India 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.
