Participation is not spreading downward this month; the larger companies are still carrying most of it.

Both lines start at 200 in the same week, so the distance between them is the whole story: the industry line is an equal-weighted index of its 9 companies. The bars underneath are trailing 12-month earnings per share, one bar per reported quarter, each member rebased to 100 at the start and the industry taking the median — so a price line pulling away from flat bars is a re-rating, not earnings. A bar turns red when that figure is lower than the quarter before. Rules are fixed and applied identically everywhere on this site: ahead by 5% or more over three months, or behind by 20% or more over a year while earnings grew 20% or more. Hover any point to read both values and the gap. This is a description of what the numbers did, not advice.

Start with scale. Then earnings trajectory. Then business quality. Only after those three agree should price leadership carry much weight.

4-Factor Sector Score

An additive sector-relative research score. The four displayed point contributions always equal the total: Growth & earnings (35), Capital efficiency (25), Valuation (20), and Relative strength (20). Missing or stale evidence is absorbed inside the affected factor, never applied as a hidden adjustment.

Growth & earnings · 35%Capital efficiency · 25%Valuation · 20%Relative strength · 20%
Constellation Energy Corporation has the strongest current balance of earnings trajectory, business quality, valuation and price confirmation, with 86.2% evidence confidence.
Digi Power X Inc. has stronger price confirmation than earnings confirmation; that is a research prompt, not permission to chase.

Missing observations are not scored as bad. Their missing weight lowers confidence and pulls the final score toward neutral. PEG is guarded: positive earnings, positive 5–60% three-year EPS growth, and a positive P/E are required.

Talen Energy Corporation's growth is 66.3% from a $3,320 million base, with 15 reported observations in the 20-quarter window. Treat the growth leader as an acceleration candidate, not as equally proven scale.

LeaderNRG Energy, Inc. · $32,384 million
Gap8.4% versus #2 · Constellation Energy Corporation
Persistence7/8 recent comparable periods
Coverage8/10 companies · 156 observations

Investor read: NRG Energy, Inc. is the scale benchmark; Talen Energy Corporation is the acceleration watch. Promote the challenger only if growth persists and converts into margin and returns.

This conclusion weakens if: NRG Energy, Inc.'s growth falls below Talen Energy Corporation's for two consecutive comparable reports while operating margin also compresses.

Revenue is compared on a common reported-currency basis. Growth is year-on-year, so seasonality does not masquerade as progress.

LeaderVistra Corp. · 26.6%
Gap26.7% versus #2 · Constellation Energy Corporation
Persistence4/8 recent comparable periods
Coverage8/10 companies · 155 observations

Investor read: Vistra Corp. sets the level benchmark; use the change leader as an inflection watch only after another comparable report confirms it.

This conclusion weakens if: The next two comparable reports reverse the current margin change signal.

Operating margin compares operating profit with revenue. Improvement is measured in percentage points, not percentage growth.

Capacity Spending & Returns On It

Constellation Energy Corporation has the highest CAPEX among the 10 Utilities - Independent Power Producers companies compared here, at $1,275 million. Vistra Corp. is next at $883 million. Digi Power X Inc. has the highest CAPEX intensity at 214.3%, so level and change sit with different companies. 10 of 10 companies report a comparable reading, the latest through Mar 2026.

What the numbers say: Constellation Energy Corporation reports $1,275 million of CAPEX; Digi Power X Inc. has the highest covered intensity at 214.3%. Coverage is only 10 of 10 companies and 169 reported observations, so this is partial evidence—not a complete sector rank.

LeaderConstellation Energy Corporation · $1,275 million
Gap44.4% versus #2 · Vistra Corp.
Persistence8/8 recent comparable periods
Coverage10/10 companies · 169 observations

Investor read: Use the CAPEX rank as a diligence queue. Verify commissioning, utilization, cash conversion and post-investment ROCE before treating spend as value creation.

This conclusion weakens if: CAPEX rises without higher utilization, operating cash flow or incremental returns.

CAPEX is cash spent on property, plant, equipment and other reported capital assets. CAPEX intensity divides that spend by revenue; high intensity is a reinvestment signal, not proof that the reinvestment will earn attractive returns.

Annual capital allocation · 6-year view
10/10 capacity base · 10/10 OCF · 10/10 CAPEX · 10/10 FCF

Capacity base is net fixed assets plus capital work in progress, straight off the reported balance sheet. It is not cash spent, so it answers a narrower question than CAPEX — but it is reported for companies whose cash-flow CAPEX is not published, which is why it leads here. Missing years remain blank; annual values are never relabelled as quarters.

Debt Load & Balance-Sheet Headroom

Digi Power X Inc. has the lowest Gross debt among the 10 Utilities - Independent Power Producers companies compared here, at $0 million. Oklo Inc. is next at $3 million. Oklo Inc. has the lowest Net debt at $2,206 million net cash, so level and change sit with different companies.

What the numbers say: Oklo Inc. has the clearest covered balance-sheet capacity with $2,206 million net cash and gross debt of $3 million. Absolute debt alone does not identify the strongest balance sheet because company scale differs; net debt and debt-to-equity carry more information.

LeaderDigi Power X Inc. · $0 million
Gap100% versus #2 · Oklo Inc.
Persistence8/8 recent comparable periods
Coverage10/10 companies · 178 observations

Investor read: Prioritize net-cash capacity and leverage relative to operating scale, not the smallest absolute rupee debt.

This conclusion weakens if: Net debt rises faster than revenue and profit for two consecutive reported periods.

Gross debt shows contractual borrowings. Net debt subtracts reported cash; a negative value means net cash. Lower debt can create capacity, but should be read against the scale and capital intensity of the business.

Return On Capital Employed

Vistra Corp. has the highest ROCE among the 10 Utilities - Independent Power Producers companies compared here, at 5%. Constellation Energy Corporation is next at 3.6%. Digi Power X Inc. has the highest ROCE change at +10.9 percentage points, so level and change sit with different companies. 10 of 10 companies report a comparable reading, the latest through Mar 2026.

What the numbers say: Vistra Corp. leads ROCE at 5%, 1.4 percentage points above Constellation Energy Corporation. Digi Power X Inc. has the strongest latest improvement at +10.9 percentage points. Read the leader beside the density of its reported history: a sparse high return is a candidate; a repeated high return is evidence of durability.

LeaderVistra Corp. · 5%
Gap38.9% versus #2 · Constellation Energy Corporation
Persistence4/8 recent comparable periods
Coverage10/10 companies · 172 observations

Investor read: Vistra Corp. sets the level benchmark; use the change leader as an inflection watch only after another comparable report confirms it.

This conclusion weakens if: The next two comparable reports reverse the current roce change signal.

ROCE asks how much operating return the business earns on the capital employed. Direction matters, but a single exceptional year should not be mistaken for durability.

Valuation Against Growth & Quality

Vistra Corp. has the lowest Guarded PEG among the 10 Utilities - Independent Power Producers companies compared here, at 0.38×. Constellation Energy Corporation is next at 1.14×. Digi Power X Inc. has the lowest P/E at 2.25×, so level and change sit with different companies. 2 of 10 companies report a comparable reading, the latest through Mar 2026.

What the numbers say: Vistra Corp. has the lowest comparable Guarded PEG at 0.38×, 66.7% below Constellation Energy Corporation. Only 2 of 10 companies pass the guard, so no broad “cheapest stock” conclusion is defensible unless the current multiple, own-history position and growth durability agree.

Investor read: Treat valuation as permission to investigate, never as a standalone reason to buy.

This conclusion weakens if: The next two comparable reports reverse the current p/e signal.

PEG is shown only when earnings are positive and three-year EPS growth is between 5% and 60%. It is recomputed consistently as the trailing P/E divided by that growth rate — reported earnings, never an expected-earnings multiple. On Indian companies it is shown only where the two data sources reconciled. A missing PEG is more honest than a low-base fiction.

Before the conclusion · check the blind spots

What can make this comparison misleading?

This Utilities - Independent Power Producers comparison names 5 specific ways its own evidence can mislead, all listed below. All 10 companies here report on comparable dates, so no rank carries a stale marker. 1 of the 8 ranked sections has fewer than three usable current readings. A high growth rate can still be a low-base artefact.

Keep these limits visible

  • A high growth rate can be a low-base artefact. The page keeps level and change separate for that reason.
  • A high ROCE can be temporary or flattered by a small capital base. Read it beside margin, cash conversion and reinvestment.
  • The 4-Factor Sector Score ranks research priority, not portfolio action. Management quality, catalysts and risks need equally fresh evidence before capital is deployed.
  • An “all companies” line chart preserves completeness, but rank changes should be checked against reporting dates before drawing a conclusion.
  • Thin comparisons: Valuation have fewer than three usable current readings.
10 · the complete set

Which companies are included?

All 10 companies in the canonical Utilities - Independent Power Producers membership are listed below, largest market value first — nothing is silently dropped, even where a company reports too little to rank. The charts above default to a selective view; this register is the complete set, with each company's own latest reporting date beside it.

AHEAD means the company is beating the index by 5% or more over three months. LAGGING, FUNDAMENTALS UP means it is 20% or more behind over a year while its trailing twelve-month earnings grew 20% or more. Both rules are fixed and applied the same way in every sector.

Utilities - Independent Power Producers company comparison FAQs

These 18 answers restate the Utilities - Independent Power Producers comparison above in question form. Every one is computed from the same 10 companies and the same reported filings as the rankings and charts, current through Mar 2026. Price and relative-strength answers run through 2026-07-28. Nothing here is estimated, and none of it is a recommendation.

Which Utilities - Independent Power Producers company is the biggest?

NRG Energy, Inc. is the largest, with trailing-twelve-month revenue of $32,384 million, ahead of Constellation Energy Corporation at $29,867 million. That covers 8 of 10 companies with comparable reporting through Mar 2026.

Which Utilities - Independent Power Producers company is growing fastest?

Talen Energy Corporation has the fastest revenue growth at 66.3% year on year, across 8 of 10 comparable companies. Fast growth off a small base is not the same as proven scale — check whether the rate holds across several quarters on the chart above before treating it as a trend.

Which Utilities - Independent Power Producers company has the best profit margins?

Vistra Corp. has the highest operating margin at 26.6%, from 8 of 10 comparable companies. Talen Energy Corporation shows the biggest recent improvement, at +45.8 percentage points. A high margin matters most when it is holding or rising, not when it is peaking.

Which Utilities - Independent Power Producers company makes the most profit?

Constellation Energy Corporation earns the most, at $3,797 million of trailing-twelve-month net profit, from 9 of 10 comparable companies. Constellation Energy Corporation has the fastest profit growth at 27.3%, though growth off a small or recovering profit base overstates how much has actually changed.

Which Utilities - Independent Power Producers company earns the highest return on capital?

Vistra Corp. leads on return on capital employed at 5%, across 10 of 10 companies. Read it beside the length of its reported history: a high return that repeats for years is evidence of a durable business, while a single high reading can be a small capital base or one good year.

Which Utilities - Independent Power Producers stock is the cheapest?

On guarded PEG — where a LOWER number is cheaper — Vistra Corp. screens cheapest at 0.38×. Only 2 of 10 companies pass the comparability guard, so this is not a sector-wide "cheapest stock" verdict. Cheap on a multiple is a reason to investigate, never a reason to buy on its own.

Which Utilities - Independent Power Producers company has the strongest balance sheet?

Digi Power X Inc. carries the lowest comparable gross debt at $0 million, from 10 of 10 companies. Absolute rupee debt alone does not settle it, because company scale differs — net debt and debt-to-equity in the chart above carry more information, and a very low-debt balance sheet can also mean under-investment.

Which Utilities - Independent Power Producers company is investing most in new capacity?

Constellation Energy Corporation reports the largest capital spending at $1,275 million, across 10 of 10 companies. Spending consumes cash before it earns anything, so treat the ranking as a diligence queue: check commissioning, utilisation and the return earned on the completed assets before reading spend as value creation.

Is the Utilities - Independent Power Producers sector beating the market?

Utilities - Independent Power Producers has underperformed S&P 500 by 17.5% over the last 52 weeks and 18.1% over 13 weeks, measured on an equal-weight index of its current members. Inside the sector, 0 of 9 covered companies are beating the market on their own. Sector strength does not transfer evenly to every stock in it.

Which Utilities - Independent Power Producers stock has the strongest price momentum?

Kenon Holdings Ltd. has the strongest relative strength against S&P 500. Relative strength answers last, after growth, quality and valuation: price can move well before the fundamentals confirm it, and sometimes without them confirming at all.

Which Utilities - Independent Power Producers company scores highest for research priority?

Constellation Energy Corporation scores 65.9 out of 100 with 86.2% evidence confidence, from 28 points on growth and earnings, 15.9 on capital efficiency, 13.9 on valuation and 8.1 on relative strength. This ranks what deserves work next. It is not a buy recommendation, and management quality, catalysts and risk still need separate research.

How many Utilities - Independent Power Producers companies does this comparison cover, and over what period?

It compares 10 listed companies over up to 20 reported quarters of fundamentals and 6 fiscal years of capital allocation, ending Mar 2026, plus weekly price and relative-strength history. Membership is the full sector list — nothing is dropped for having thin data.

What is the total market cap of the Utilities - Independent Power Producers sector?

The 10 Utilities - Independent Power Producers companies on this page carry $207,117 million of combined market value. Constellation Energy Corporation is the largest at $92,782 million, about 45% of the sector's total on its own. Market value moves with price, so this reading is dated 2026-07-28.

What is the Utilities - Independent Power Producers sector's P/E ratio?

The median price-to-earnings ratio across the 10 Utilities - Independent Power Producers companies on this page is 34.4×, measured on the 8 that report a comparable figure. A sector-level history for this multiple is not held here, so this is a cross-section of today, not a comparison with the sector’s own past. Figures are as of 2026-07-28.

How is the Utilities - Independent Power Producers sector performing?

0 of the 9 covered Utilities - Independent Power Producers companies are beating S&P 500 on Mansfield relative strength. The sector itself is 17.5% behind S&P 500 over 52 weeks on an equal-weight index of its current members. Readings are as of 2026-07-28.

How many Utilities - Independent Power Producers stocks are listed in the US?

This comparison covers 10 listed Utilities - Independent Power Producers companies in the US, each above the size floor the site applies. The full ranked list is on this page, with reported fundamentals through Mar 2026. Membership is the full industry list — nothing is dropped for having thin data.

Why are some values on this page blank?

A blank means that company did not report a comparable figure for that period, so nothing is shown. Missing observations are never interpolated, carried forward, or replaced with a similar-looking accounting line, and a company with missing evidence has its research score pulled toward neutral rather than being scored as bad.

Is this investment advice?

No. Every figure here is a deterministic calculation from reported company filings and market data, published for research. It contains no recommendation to buy or sell any security, does not account for your circumstances, and is not a substitute for advice from a licensed adviser.
