Price verdict withheld — owner-earnings floor unreliable
The five investor questions
2022–2026 (latest 5 aligned FYs; v3 window cap 5): revenue $31.9B to $25.9B, decreasing; diluted EPS 6.97 to 1.68, decreasing.
Median gross margin 11.8% over 10y, stable.
Not enough years of ROIC data to score returns on capital.
Net debt/EBITDA 21.3x, interest coverage 4x.
Owner earnings -9.8%/yr, share count shrinking (buybacks).
The returnsOnCapital component abstained: Not enough years of ROIC data to score returns on capital. The other four 20% weights were renormalized over the scored 80%.
Price vs. conservative owner-earnings floor
A cautious baseline, not a price target: what the shares may support if normalized owner earnings simply hold steady.
- Owner earnings (normalized)
- $485M
- Owner-earnings floor / share
- $37.99
- Capped-growth comparison / share
- $37.99
- Recent price
- $58.29
- Price vs. owner-earnings floor
- 53% above owner-earnings floor
What today’s price assumes: owner earnings growing ~9%/yr over 5 years. The floor assumes owner earnings stay flat (0% growth).
How to read this
We solve for the constant annual change in owner earnings that would make the five-year floor equal today’s price. This keeps the existing model inputs and calculation unchanged; it is an expectations lens, not a forecast.
This floor assumes trailing owner earnings persist — unreliable for declining businesses. KMX revenue fell in each of the three most recent year-over-year FY comparisons, so this floor is flagged as unreliable for this company.
Cohort context: median current price is 239% above the floor across 48 of the current top 50 companies by Moat Score with both values.

19 years of fundamentals
The business, in plain English
CARMAX, INC. booked $25.9B of revenue in FY2026 in the Consumer Discretionary sector and kept 10.8% of it as gross profit — a thin-margin business by that measure. After every other cost, 1.0% of each revenue dollar reached the bottom line.
Across the filed record, revenue grew from $7.0B (FY2009) to $25.9B (FY2026) — about 8.0% a year compounded over 17 years.
The balance sheet carried $18.1B of total debt in FY2026 against $247M of owner earnings — roughly 73.0 years of owner earnings to retire it all. Balance-Sheet Safety scores it 6/100.
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 KMX’s filings for these years — we don’t estimate it.
Gaps in a line mean that item isn’t in KMX’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 CARMAX, INC.’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 KMX 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, KMX 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.

Common questions about KMX
- Does CARMAX, INC. have an economic moat?
- Based on its FY2026 SEC filings, the Moat Index scores CARMAX, INC. (KMX) 20.9 out of 100 — below the Shallow-moat bar, so no moat. The five questions behind that score begin at 20% each; if exactly one genuinely lacks data, the other four weights are renormalized and disclosed. revenue and EPS trend 20, pricing power 18, returns on capital not measurable from the filings, balance-sheet safety 6, capital discipline 40.
- Is KMX trading below the conservative owner-earnings estimate?
- The conservative owner-earnings floor is $37.99 per share. It capitalizes normalized owner earnings at a 9% rate and assumes 0% growth. Versus a recent price of $58.29, that is 53% above owner-earnings floor. The model also publishes a capped-growth comparison, but the floor is the cautious baseline. It assumes trailing owner earnings persist and is unreliable for declining businesses. This is an educational estimate from primary SEC filings, not intrinsic value as a fact or investment advice.
- How has KMX's Moat Score changed over time?
- The record logs 16 readings since Jul 17, 2026; the latest reads 20.9 out of 100 (no moat). No tier changes on record yet. (Methodology or normalizer upgrades on Jul 20, 2026, Jul 23, 2026, Jul 26, 2026 re-based the score; readings across versions aren't compared.)
