Analyst mean 2.07 · 30 analysts · 33% bullishA plain-language read of the business, how it actually earns, where the edge is, and the economics of every reported segment — taken from the annual report and investor presentation, not a one-line industry label.
Numbered markers are corporate actions and, once the filings are read, capital and governance events. Prices are split-adjusted so the series is continuous.
The three to six things that actually matter about this company, each with the exact filing and note it came from — never a fact without the context that makes it meaningful.
What the numbers mean when read together — computed from the filings, not a score.
Capital work-in-progress has stayed high (34% of fixed assets) without converting to productive assets — worth checking whether projects are genuinely progressing.
Why this reading: Noted with caution — worth watching, but not yet conclusive on its own. Business has ups and downs; one soft reading is not a verdict.
CWIP ₹116,272 cr vs ₹118,729 cr two years earlier, against fixed assets ₹346,073 cr. Perennial CWIP that never becomes a fixed asset can hide stalled projects or capitalised costs that should have been expensed.
Operating cash is 226% of trailing profit — the earnings are converting to real cash, not just accruals.
Why this reading: A positive signal: cash conversion at or above ~0.9 means reported profit is showing up as actual cash.
Operating cash ₹112,719 cr against trailing net profit ₹49,793 cr. Consistent conversion near or above 1.0 is a hallmark of genuine earnings.
Both revenue and profit grew over the last year (7.1% and 11.7%) — growth is translating to the bottom line.
Why this reading: A positive signal in the numbers, shown for balance alongside the concerns.
Trailing revenue ₹704,122 cr, trailing profit ₹44,793 cr. Profit growing at least as fast as revenue indicates operating leverage or pricing power.
Free cash flow is positive and consistent — the business funds itself after capex.
Why this reading: A positive signal in the numbers, shown for balance alongside the concerns.
Latest free cash flow ₹72,219 cr. Negative in only 0 of 12 years. A self-funding business needs less external capital and dilutes less.

Needs current assets and current liabilities.
Piotroski F-Score — fundamental momentum — Joseph Piotroski, University of Chicago, 2000, in a study of whether accounting signals could improve returns among cheap stocks.
Nine yes-or-no tests across profitability, leverage and operating efficiency. Each pass scores one. It asks a narrow question: is this business getting better or worse on its own terms, year over year?
How to read it7 or more suggests improving fundamentals; 3 or fewer suggests deterioration. It measures direction, not quality — a weak company improving can score higher than a strong one holding steady.
Where it failsA single year of comparison, so one unusual year distorts it. Says nothing about valuation, competitive position or management. Piotroski designed it to rank already-cheap stocks, not to judge a company in isolation.
Needs trade receivables, current assets, other expenses.
Accruals are -8.2% of assets. Free cash flow negative in 0 of 12 years.
DuPont decomposition — Devised inside the DuPont Corporation in the 1920s and still the standard way to read a return on equity.
Splits return on equity into its three sources, so the same headline number can be traced to very different businesses.
How to read itA 20% ROE built on margin and turnover is a different proposition from a 20% ROE built on 3× leverage. The first survives a downturn; the second amplifies it.
Where it failsA single year. Negative equity makes it meaningless. Leverage is structural for lenders, so the third term carries no signal there.
Capital and revenue are growing at broadly similar rates — the asset base is being used, not just added to.

Money going in far faster than revenue coming out. For an incubator this is expected — the test is whether it eventually converts.Needs more balance-sheet detail (only 3 of 6 flags testable).
NOPAT over equity plus debt less cash, at a notional 25% tax. Incremental ROIC is the return on money put in since then — the number that decides whether growth creates value or consumes it.
Return on invested capital, and incremental ROIC — Standard in corporate finance; the incremental form was popularised by Michael Mauboussin as the test of whether growth creates value.
ROIC measures what the business earns on all the capital it employs — equity plus debt, less cash. Incremental ROIC asks a sharper question: what has it earned on the money put in since a chosen year?
How to read itROIC comfortably above the cost of capital — call it 11–13% in India — means growth compounds. Below it, growth consumes. Incremental below headline means recent investment is earning less than the legacy business.
Where it failsDistorted in the year of a large acquisition. Understated for companies mid-build, where capital is deployed but capacity has not yet been commissioned — an incubator will look poor until it does not.
Read downward. Cash can cover EBITDA and still not survive capex — the third rung is where a capital-hungry business shows itself.
The earnings quality ladder — Not a named model — the standard sequence an analyst walks when testing whether reported profit is real.
Three ratios read in order, each stricter than the last.
How to read itRead downward. Each rung failing where the one above passed tells you exactly where the cash is going.
Where it failsA single year of heavy capex depresses the third rung legitimately. Judge it across a cycle.
The growth rate that makes today's market value equal the discounted cash flows, at a 11.5% discount rate and 4.0% terminal growth. Not a forecast — the arithmetic of what is already in the price. Compare it with what the business has actually delivered.
Reverse DCF — the growth already in the price — A standard inversion of discounted cash flow, used to avoid the forecasting problem entirely.
Instead of forecasting cash flows and deriving a value, it takes today's market value as given and solves for the growth rate that would justify it. The output is not a view — it is the arithmetic of what the market is currently assuming.
How to read itCompare it with what the business has actually delivered. A price implying 30% a year against a decade of 15% is a demanding assumption; the reverse is a modest one.
Where it failsUseless when free cash flow is negative or unusually depressed, which is common mid-capex. Highly sensitive to the discount rate — a point either way moves the answer materially.
Against a policy rate near 6%, most sound Indian corporates borrow between 7% and 10%.
Cost of debt — Interest expense over average borrowings — the effective rate the company actually pays.
What the lenders charge, which is a market verdict on credit quality that no rating agency delay affects.
How to read itAgainst a policy rate near 6%, most sound Indian corporates borrow between 7% and 10%. Read the direction over years as much as the level.
Where it failsUnderstated where a large share of interest is capitalised into projects under construction. Not meaningful for lenders, where interest is cost of goods.
Some figures appear twice on this page with different values. That is not an error — they sit on different bases. The live feed reports a rolling twelve months; everything computed here comes from the last audited statements. Both are shown so you can see which is which.
Where the two disagree, every model, screen and ratio computed on this page uses the filed figure, because the rest of the page is on that basis.
Models that need these lines are withheld rather than estimated: net worth, current assets, current liabilities, trade receivables, inventory, net block. Nothing on this page is back-solved from a figure the company did not publish.
Each framework below is a set of stated, mechanical criteria from published work, run against this company's own filed numbers. Passing or failing a screen is not a verdict — different frameworks disagree by design, and that disagreement is itself informative.
Benjamin Graham's stated criteria for a defensive stock, applied to the filed numbers. A company failing several is not disqualified — Graham designed these to be deliberately strict.
Two ratios only: what the business earns on its capital, and what you pay for those earnings. Designed to be ranked across a universe rather than read in isolation.
The fundamental half of William O'Neil's framework. The market and leadership components are judgement calls and are not scored here.
The characteristics long-term holders commonly look for: cash-backed earnings, high returns on capital, and debt that never forces a decision.
Median of the companies we hold in the same sector (Oil Gas & Consumable Fuels). Every figure on both sides is the live feed's trailing twelve months, so the two are measured the same way whatever depth of extraction this company has had. A number only means something next to something else — expensive against the market and cheap against peers are different facts.
Bars are revenue; the line is net margin. Revenue rising while the line falls is the shape worth noticing.
Operating cash first, then what the business spent and raised.
One year is a snapshot. These are the two lines that matter across a cycle.
Rising debtor or inventory days against flat sales is the earliest visible sign of stress.

Cash from operations is the number profit has to answer to. Free cash flow is what remains after the business pays for its own growth.
The part no one reads: the auditor's opinion, the contingent liabilities buried in the notes, the covenants, and the claims in the deck placed beside the figures that test them.
Where analysts pressed management on the earnings call, and exactly how management answered — the questions that were hardest to answer are usually the ones that matter.
These are coverage counts, not ratings. Each one asks a fixed set of questions of the filings and reports how many the company answered. A company that discloses nothing counts nothing here — that is a statement about the disclosure, not about the business.
The same read, applied to the companies this one competes with.
Oil & Natural Gas Corporation Ltd. reported revenue of ₹2.05 lakh cr for April to June 2026, +25.7% on the year and +17.9% on the quarter. That is faster than this quarter has grown in recent years (−0.2% on average), so the year-on-year number is not just the season. It is the highest quarterly revenue in the last 12 quarters on record. Over the last four quarters revenue comes to ₹7.04 lakh cr, +7.1% on the four before.
Operating profit (EBITDA) was ₹15,485 cr, a margin of 7.6%, −825 bps on the year and −703 bps on the quarter. It is the narrowest margin of the last 8 quarters (range 7.6% to 16.8%). Operating costs grew +38.0%, faster than revenue at +25.7%, so operating profit grew less than sales.
Net profit was ₹6,554 cr, −43.3% on the year and −52.1% on the quarter, with earnings per share of ₹9.46. Profit before other income, one-offs and tax fell 75.8%, so 33 points of the headline growth came from outside the core business. The tax rate was 7% against an average of 27% over the previous 8 quarters, which lifted profit this quarter. Profit over the last four quarters totals ₹44,793 cr, +11.7% on the four before.
Refining and marketing profits swing with crude and product margins, and inventory gains or losses can move a single quarter sharply. The quarterly statements do not carry refining margins, throughput and inventory gains or losses; those come with the filing read.
On earnings per share of ₹34.59 over the last four quarters, the stock at ₹222.08 trades at 6.4 times trailing earnings.
Written from the quarterly statements. The filing read adds the balance sheet and cash flow, the auditor's review, segment results, one-off items line by line and what management said on the call.
Half or more of pre-tax profit came from other income. What is it, and does it repeat?
Other income was 55% of profit before tax, against 16% a year earlier.
Source: Quarterly statements
A lower tax rate lifted profit. Is the lower rate going to last?
Effective tax rate 7.0% against 26.5% over the previous quarters, worth about ₹1,367 cr of profit.
Source: Quarterly statements
Operating margin fell sharply on the year. Pricing, input costs, or mix?
Expected for Oil, gas and energy: Margins move with crude and inventory gains each quarter. EBITDA margin 7.6%, −825 bps on the year (−703 bps on the quarter).
