The five investor questions

95

2022–2026 (latest 5 aligned FYs; v3 window cap 5): revenue $227.0B to $303.2B, increasing; diluted EPS 13.14 to 20.76, increasing.

27

Median gross margin 12.8% over 10y, very stable.

100

Median ROIC 34.1%, above the 12% hurdle in 100% of years.

100

Net cash position — no leverage risk.

77

Owner earnings changed +14.7%/yr over up to the ten most recent annual observations.

Price vs. value if growth stopped today

A cautious baseline, not a price target: what the shares may support if normalized owner earnings simply hold steady.

$184.66
$299.16
$982.00
432% above value if growth stopped today

What today’s price assumes: owner earnings growing ~40%/yr over 5 years. The zero-growth estimate 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 zero-growth estimate equal today’s price. This keeps the existing model inputs and calculation unchanged; it is an expectations lens, not a forecast.

This zero-growth estimate assumes trailing owner earnings persist — unreliable for declining businesses. The recent FY revenue series does not trigger the three-consecutive-declines flag.

Among the current top-score group, the median current price is 240% above the zero-growth estimate across 49 of the current top 50 companies by Moat Score with both values.

Model details under moat-index@3.0.0: zero-growth multiple 11.1×, capped-growth comparison at no more than 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.

20 years of fundamentals

The business, in plain English

COSTCO WHOLESALE CORP /NEW booked $303.2B of revenue in FY2026 in the Consumer Discretionary sector and kept 12.8% of it as gross profit — a thin-margin business by that measure. After every other cost, 3.0% of each revenue dollar reached the bottom line.

Across the filed record, revenue grew from $72.5B (FY2008) to $303.2B (FY2026) — about 8.3% a year compounded over 18 years.

It earned 40.4% on invested capital in the latest filed year, FY2026. Across the full 19-year measurable filed record, median ROIC was 21.4%. Over the v3 recent window (10 measurable filed years), median ROIC was 34.1%. The Returns on Capital filter above scores it 100/100.

The balance sheet carried $6.2B of total debt in FY2026 against $9.2B of owner earnings — roughly 0.7 years of owner earnings to retire it all. Balance-Sheet Safety scores it 100/100.

Put together: Returns on Capital is the strongest of the five filters (100/100) and Pricing Power the weakest (27/100), which is how COST lands at 80/100 — a Narrow moat.

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.

The explained ROIC gaps have filed inputs but no meaningful positive invested-capital denominator. Other gaps mean the item is not in the 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.

Insider activity

Form 4 reports mix P/S market or private transactions with compensation-plan mechanics. Activity casually described as “insider selling” can include compensation mechanics; awards, tax withholding, and option exercises are shown by their exact filed class here, never collapsed into “Bought” or “Sold.”

These are disclosed filing facts and arithmetic aggregates, not a signal or verdict.

This machine-readable surface covers SEC ownership filings from 2003; it does not represent earlier paper-era records.

Records still being gathered — partial as of retrieval Oct 15, 2026.

6 filings were skipped because the SEC primary document returned 404; the omission is disclosed and aggregates are withheld.

Among the rows shown, A/F/M acquisition, payment or withholding, and exercise or conversion rows outnumber S sale rows (14 versus 3). The filing codes alone do not establish that every such row arose from a compensation plan.

Trailing-12-month totals and the 90-day cluster result are withheld because this issuer walk is incomplete.

Track record

How COSTCO WHOLESALE CORP /NEW’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.

Point-in-time scores 2011–2025, one methodology version · reconstructed from filings on file each Dec 31 — never with hindsight

Point-in-time Moat Score (dot colored by tier)Indexed price (total-return (dividends reinvested))Rated Wide-moat that year

How to read this: each dot is what the engine would have scored COST on that December 31; the line below is its total-return price path (dividends reinvested) in the years since.

0406080100WideNarrowShallowNo moatPoint-in-time Moat Score1002005001,000Indexed price · log scale (2012 = 100)201120142017202020232026

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 5 years COST rated Wide-moat (2021, 2022, 2023, 2024 and 2025), the median forward total return that followed — measured only after each year’s filings were public — was:

  • 1 year 18% vs the S&P 500’s 20% (price basis) · median over 4 years
  • 3 years 82% vs the S&P 500’s 51% (price basis) · median over 2 years
  • 5 years None of the 5 years it rated Wide has a fully elapsed 5-year window with a benchmark to compare against yet.

These are medians computed from the data, not a claim about any one year. The company figures are total returns (dividends reinvested); the S&P 500 is the price-only ^GSPC index, which excludes dividends and so understates the index — the gap flatters the company. A quality rating is not a return forecast, and past returns don’t predict future ones. Educational only, not investment advice.

Common questions about COST

Does COSTCO WHOLESALE CORP /NEW have an economic moat?
Based on its FY2026 SEC filings, the Moat Index scores COSTCO WHOLESALE CORP /NEW (COST) 79.8 out of 100 — a Narrow 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 95, pricing power 27, returns on capital 100, balance-sheet safety 100, capital allocation 77.
Is COST trading below the conservative owner-earnings estimate?
The value if growth stopped today — a zero-growth baseline — is $184.66 per share. It capitalizes normalized owner earnings at a 9% rate and assumes 0% growth. Versus a recent price of $982.00, that is 432% above value if growth stopped today. The model also publishes a capped-growth comparison, but the zero-growth estimate 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 COST's Moat Score changed over time?
The record logs 32 readings since Jul 17, 2026; the latest reads 79.8 out of 100 (narrow moat). Tier changes so far: Wide moat → Narrow moat on Oct 10, 2026. (Methodology or normalizer upgrades on Jul 17, 2026, Jul 20, 2026, Jul 23, 2026, Jul 26, 2026 re-based the score; readings across versions aren't compared.) The history is append-only — readings are only ever added, never rewritten.
