Tata Power Company 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.

Tata Power Company Ltd trades at ₹377, in a confirmed uptrend and 13 weeks into that stage. That is −4.3% against its own 200-day average. It sits at 32% of a 52-week range of ₹345 to ₹445. On relative strength it is currently behind the NIFTY 500 on a trailing-13-week view (8 weeks and counting).

Today the stock is in a confirmed uptrend — week 13 of stage 2. At ₹377 it trades −4.3% versus its 200-day average and sits at 32% of its 52-week range (₹345–₹445).

Against the market, two honest reads. Cumulative: over the last 10.3 years the stock moved +539% while the NIFTY 500 moved +274% — ahead of the index over the full window. Recent form: on a trailing-13-week view the stock is currently behind (8 weeks and counting; last ahead the week of 2026-06-12) — 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.

→ The trend is one thing; the bill is another. Are you paying up for it? Next: the P/E sits at the 65th percentile of its own range.

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.

Tata Power Company Ltd trades at 31.1× P/E, mid-range by its own standards (65th percentile). Its long-run median P/E is 25.9×, measured across 10.4 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 31.1× is mid-range by its own standards (65th percentile), against a long-run median of 25.9× measured over 10.4 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 −5.6% against a −7.5% price move — earnings outran the price, pushing the multiple DOWN its own range.

The price move, decomposed: over 5y, of the +24.9%/yr price move, ~+27.5%/yr came from earnings growth and ~−2.6 pp from the multiple (compressing); over 10y, of the +18.1%/yr price move, ~+20.1%/yr came from earnings growth and ~−2.0 pp from the multiple (compressing). 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 full against its own past, so the story rests on the earnings line underneath it, not the multiple.

→ Cheap or dear rides on the earnings. Are they actually growing? Next: the fundamental stage — where the business sits in its arc, and how growth has compounded.

Stage: Deteriorating 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).

Tata Power Company Ltd reads as deteriorating on its fundamental arc. Deteriorating — revenue and EPS growth are shrinking (revenue growth −4.7% latest against +23.5% at its 12-quarter best), ROCE holding at 11.0%. The read is built from 12 quarters across 4 curves, on partial evidence.

🚨 Why it matters: falling curves mean every cheap-looking ratio below needs a discount for direction.

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.

→ The stage names the trajectory. Next: the revenue line that produces it, quarter by quarter.

4-Factor Sector Score

31.3/100 — rank 20 of 20 in Power - Generation/Distribution · 93% evidence confidence

Tata Power Company Ltd scores 31.3 out of 100 against the 20 companies it is compared with in Power - Generation/Distribution, ranking 20. Balanced evidence: keep at normal research priority and require another comparable period before raising conviction.

The four contributions add to the total exactly: 8.6 + 10.4 + 5.2 + 7.1 = 31.3. 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.

Tata Power Company Ltd reported ₹14,900 Cr of revenue in the Mar 26 quarter, −12.8% year on year. Over 10 years it has compounded at 7.8% a year. The last full year, FY26, came in at ₹62,429 Cr. The last four reported quarters add to ₹62,428 Cr.

Tata Power Company Ltd reported ₹14,900 Cr of revenue in the Mar 26 quarter, −12.8% year on year. Over 10 years it has compounded at 7.8% a year. The last full year, FY26, came in at ₹62,429 Cr. The last four reported quarters add to ₹62,428 Cr.

FY26 revenue came in at ₹62,429 Cr (−4.7% on the year), capping 10 years at 7.8% compound. The latest quarter (Mar 26) printed ₹14,900 Cr, −12.8% year on year.

Pace check: the last four quarters averaged −4.7% growth against the decade's 7.8% — the current year is running slower than its own long-run rate.

Acceleration check: trailing-twelve-month revenue grew −4.7% over the last 4 quarters against +0.8%/yr over the last 8 — rolling over; TTM profit +7.1% vs +9.3%/yr — stabilising.

→ Revenue slipped — did margins hold as it scaled? Next: 17.0% this quarter (−2.0 pp YoY).

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.

Tata Power Company Ltd's operating margin is 17.0% in the Mar 26 quarter, −2.0 percentage points against the same quarter a year ago. Across 13 fiscal years the operating margin has ranged 7.0% to 23.0%. The current quarter sits inside that band.

Tata Power Company Ltd's operating margin is 17.0% in the Mar 26 quarter, −2.0 percentage points against the same quarter a year ago. Across 13 fiscal years the operating margin has ranged 7.0% to 23.0%. The current quarter sits inside that band.

The latest quarter's operating margin is 17.0%, −2.0 pp against the same quarter a year ago. Across 13 fiscal years the operating margin has ranged 7.0%–23.0%.

🚨 Why the margin moved: operating margin went −1.5 pp year on year while gross margin went +2.4 pp — the loss came mostly from the gross line: input costs and pricing.

→ Margins slipped — did that reach the bottom line? Next: profit +8.4% in the latest quarter.

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

Tata Power Company Ltd earned ₹1,416 Cr of net profit in the Mar 26 quarter, +8.4% year on year. It is the 12th consecutive quarter of growth. Full-year FY26 profit was ₹5,118 Cr. The 10-year compound rate is 20.6%. That is 9.5% of the quarter's revenue. The same quarter a year earlier earned ₹1,306 Cr.

The 10-year compound rate is 20.6%. That is 9.5% of the quarter's revenue. The same quarter a year earlier earned ₹1,306 Cr.

Mar 26 profit was ₹1,416 Cr, +8.4% year on year — the 12th consecutive quarter of growth. On the full year, FY26 printed ₹5,118 Cr (+7.2%), and the 10-year compound rate is 20.6%.

Why profit moved: revenue contributed −12.8% and the margin −2.0 pp — the quarter was revenue-led despite a thinner margin.

Pace comparison, last four quarters: profit +7.2% vs revenue −4.7%. 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.

→ Profit rose — but did the cash follow? Next: 220% of the last 3 years' profit arrived as cash.

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 220% of Tata Power Company Ltd's reported profit arrived as operating cash — the cash follows the profit. In FY26 that was ₹5,993 Cr of operating cash against ₹5,118 Cr of profit. After ₹15,646 Cr of capital spending, ₹−9,653 Cr was left as free cash.

FY26: operating cash of ₹5,993 Cr against reported profit of ₹5,118 Cr, leaving free cash of ₹−9,653 Cr after ₹15,646 Cr of capital spending. Across the last 3 fiscal years the conversion rate is 220% 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 220%: the cash cycle tightened 32 days between FY21 and FY26 — cash that used to wait in the cycle now reaches the bank sooner.

Router verdict: the bigger cash user is investment — capital spending ran 3.7× depreciation over three years, so the next section's job is to check what that build-out is buying.

→ So follow the cash to where it goes. Next: ₹47,479 Cr of building over 3 years.

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).

Tata Power Company Ltd's cash conversion cycle runs 26 days in FY26, down from 58 days in FY21. Capital spending ran ₹47,479 Cr over the last 3 years. At FY26 sales of ₹62,429 Cr each day of that cycle holds about ₹171 Cr, so roughly ₹4,447 Cr sits inside the business at any moment.

FY26: debtors at 26 days, inventory at 217 days — roughly 7.1 months of stock waiting to sell; that is where the cash sits while it waits — for a full cycle of 26 days, tighter than FY21's 58.

The full loop: cash goes out to suppliers and production on day 0; stock waits 217 days to sell; customers pay about 26 days after that; and suppliers themselves are paid at 459 days — netting out to the 26-day cycle.

In money terms: at FY26 sales of ₹62,429 Cr, each day of the cycle holds about ₹171 Cr — so the 26-day loop keeps roughly ₹4,447 Cr sitting inside the business at any moment.

On the investment side: capital spending of ₹47,479 Cr over the last 3 fiscal years against ₹12,714 Cr of depreciation — the company is building well ahead of wear-and-tear. Capital work-in-progress stands at ₹14,595 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.

→ Does all this activity actually earn its cost of capital? Next: ROCE is 11% and the ROIC − WACC spread is −7.6 pp.

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.

Tata Power Company Ltd earns a ROCE of 11% in FY26. That is up from a trough of 5% in FY16. Return on invested capital clears the cost of that capital by −7.6 percentage points, so growth here is not yet paying for the capital it uses. The wiring behind it is 8.2% net margin on 0.36× asset turns.

FY26 ROCE is 11%, recovered from a FY16 trough of 5% — the full ladder below shows the fall and the climb, undoctored.

🚨 Why the return is what it is — the wiring (FY26): 8.2% net margin × 0.36× asset turns × 4.42× balance-sheet leverage ≈ 13.0% on equity. Margin does its share; leverage is a meaningful part of the equation.

The capstone test — ROIC − WACC: 4.4% − 12.0% = a −7.6 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.

→ Returns like these — is the balance sheet borrowing to make them? Next: debt-to-equity is 1.93.

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.

Tata Power Company Ltd carries total debt of ₹79,903 Cr against shareholder equity of ₹47,547 Cr as of Mar 26, a debt-to-equity of 1.68. On the annual view that ratio went from 1.94 in FY22 to 1.68 in FY26. Read the returns elsewhere on this page with that leverage in mind.

Mar 26: total debt of ₹79,903 Cr against shareholder equity of ₹47,547 Cr — a debt-to-equity of 1.68. On the annual view, debt-to-equity went from 1.94 (FY22) to 1.68 (FY26). Read the returns on this page with that leverage in mind.

→ Who owns this, and are they adding or leaving? Next: Domestic institutions added 2.6 points over 8 quarters.

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.

Domestic institutions added 2.6 points of Tata Power Company Ltd over 8 quarters, the biggest move on the register. That takes domestic institutions to 18.1% of the company. Foreign institutions moved +0.5 points over the same window, to 10.0%. The register is read on the four disclosed classes only; nothing is inferred between filings.

The register over the last two years — Domestic institutions: +2.6 points over 8 quarters to 18.1%; Foreign institutions: +0.5 points over 8 quarters to 10.0%; Promoters: +0.0 points over 8 quarters to 46.9%.

Why the register moved: domestic institutions drove it (+2.6 points), alongside foreign institutions (+0.5 points) — steady accumulation by institutions reading the same numbers this page reads.

→ One last check: does the safety math agree? Next: the balance-sheet safety line.

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.

Tata Power Company 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.
