The five investor questions
2017–2025: revenue 5430000000.00 to 17586000000.00, increasing; diluted EPS -0.59 to 2.18, increasing.
Not enough years of gross-margin data to score pricing power.
Median ROIC 6.2%, above the 12% hurdle in 22% of years.
Net debt/EBITDA 4.6x, interest coverage 2x.
Owner earnings +14.0%/yr, share count shrinking (buybacks).
The pricingPower component abstained: Not enough years of gross-margin data to score pricing power. The other four 20% weights were renormalized over the scored 80%.

Conservative range under moat-index@2.0.0: low end 11.1×, high end capped at 18×; 9% discount rate; high-end growth 4% (capped at 4%) using min(5y revenue CAGR, 5y diluted-EPS CAGR), clamped to 0%–4%; maintenance capex uses min(capex, D&A); abstain when D&A is unavailable. This is a disclosed model range, not intrinsic value as fact.
10 years of fundamentals
The business, in plain English
Across the filed record, revenue grew from $5.4B (FY2017) to $17.6B (FY2025) — about 15.8% a year compounded over 8 years.
It earned 6.9% on invested capital in FY2025, with a median of 6.2% across 9 filed years. The Returns on Capital filter above scores it 13/100.
The balance sheet carried $18.8B of total debt in FY2025 against $944.0M of owner earnings — roughly 20.0 years of owner earnings to retire it all. Balance-Sheet Safety scores it 0/100.
The share count fell 20.9% between FY2016 and FY2025 — management has been retiring shares, which concentrates each remaining owner's claim. Capital Discipline scores it 100/100.
This breakdown is generated from the filed numbers and sub-scores above — no outside narrative, no estimates. Where a filing doesn’t disclose an input, the sentence that would need it is omitted instead of guessed.
Not disclosed in VST’s filings for these years — we don’t estimate it.
Gaps in a line mean that item isn’t in VST’s filings for that year — the series is never interpolated or estimated. The Table view lists every filed value, including operating and net margins, total debt, and share count.

Track record
How Vistra Corp.’s moat rated in each of the years we can reconstruct from its filings — scored only on what was knowable at the time — and what its price and returns did afterward. The score never saw a price; the two are joined only in hindsight, for education, not as a signal.
How to read this: each dot is what the engine would have scored VST on that December 31; the line below is its total-return price path (dividends reinvested) in the years since.
Two tracks, one timeline: the score has its own 0–100 scale (top), the price its own 100-based scale (bottom) — never a shared axis. The price path is a total-return (dividends reinvested) index built from the same data the forward returns use; gaps in the score line are years with no reconstructed rating (see the table for why). The Table view carries every value.
What followed, in the years it rated Wide
In the reconstructed history shown, VST did not rate Wide-moat in any year, so there is no wide-moat track record to report. That absence is itself the honest answer — we don’t manufacture a comparison where the rating never earned one.

- Based on its FY2025 SEC filings, the Moat Index scores Vistra Corp. (VST) 45.1 out of 100 — a Shallow moat.

- Is VST trading below the conservative owner-earnings estimate?
- The owner-earnings value range is $31.03–$50.26 per share. It capitalizes normalized owner earnings at a 9% rate; the low end assumes 0% growth and the high end uses 4% growth, capped at 4% and 18×. Versus a recent price of $157.99, that is 214% above high estimate relative to the high estimate. This is a conservative educational estimate from primary SEC filings, not intrinsic value as a fact or investment advice.
