## Revenue Scale & Growth Durability

What the numbers say: NRG Energy, Inc. is the scale leader at $32,384 million, 8.4% ahead of Constellation Energy Corporation. Talen Energy Corporation's growth is 66.3% from a $3,320 million base, with 15 reported observations in the 20-quarter window.

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.

## Operating Economics & Margin Trend

What the numbers say: Vistra Corp. leads opm at 26.6%; Talen Energy Corporation leads margin change at +45.8 percentage points.

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

Evidence: Vistra Corp. · 26.6% | 26.7% versus #2 · Constellation Energy Corporation | 4/8 recent comparable periods | 8/10 companies · 148 observations

## Return On Capital Employed

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.

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.

Evidence: Vistra Corp. · 5% | 38.9% versus #2 · Constellation Energy Corporation | 4/8 recent comparable periods | 10/10 companies · 172 observations

Definition: 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

What the numbers say: Vistra Corp. has the lowest comparable PEG at 0.38×, 66.7% below Constellation Energy Corporation. Only 2 of 10 companies have earnings and growth steady enough for the ratio to mean anything, 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.

Evidence: Vistra Corp. · 0.38× | 66.7% versus #2 · Constellation Energy Corporation | 0/8 recent comparable periods | 2/10 companies · 4 observations

Definition: 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 feeds agreed. Where any of that fails the ratio is left out rather than printed: a P/E divided by a loss, or by growth measured off a tiny base, is a number that looks precise and means nothing.

## What can make this comparison misleading?
- 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.
