The five investor questions

92

2021–2025 (latest 5 aligned FYs; v3 window cap 5): revenue $13.0B to $17.9B, increasing; diluted EPS 19.84 to 35.40, increasing.

66

Median gross margin 38.9% over 10y, very stable.

100

Median ROIC 27.1%, above the 12% hurdle in 100% of years.

91

Net debt/EBITDA 0.7x, interest coverage 31x.

100

Owner earnings changed +12.2%/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.

Above value if growth stopped todayBelow value if growth stopped today
233% above value if growth stopped today
$1.7B
$400.13
$648.22
$1330.62
233% above value if growth stopped today

What today’s price assumes: owner earnings growing ~27%/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.

20 years of fundamentals

The business, in plain English

W.W. Grainger, Inc. booked $17.9B of revenue in FY2025 in the Industrials sector and kept 39.1% of it as gross profit — a solid-margin business by that measure. After every other cost, 9.5% of each revenue dollar reached the bottom line.

Across the filed record, revenue grew from $6.4B (FY2007) to $17.9B (FY2025) — about 5.9% a year compounded over 18 years.

It earned 32.9% on invested capital in the latest filed year, FY2025. Across the full 19-year measurable filed record, median ROIC was 24.3%. Over the v3 recent window (10 measurable filed years), median ROIC was 27.1%. The Returns on Capital filter above scores it 100/100.

The balance sheet carried $2.5B of total debt in FY2025 against $1.7B of owner earnings — roughly 1.5 years of owner earnings to retire it all. Balance-Sheet Safety scores it 91/100.

Put together: Returns on Capital is the strongest of the five filters (100/100) and Pricing Power the weakest (66/100), which is how GWW lands at 90/100 — a Wide 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.

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

The insider-filing service is temporarily unavailable, so no partial or guessed answer is shown for GWW.

Track record

How W.W. Grainger, 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.

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 GWW on that December 31; the line below is its total-return price path (dividends reinvested) in the years since.

0406080100WideNarrowShallowNo moatPoint-in-time Moat Score100200500Indexed 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 7 years GWW rated Wide-moat (2014, 2015, 2020, 2022, 2023, 2024 and 2025), the median forward total return that followed — measured only after each year’s filings were public — was:

  • 1 year 24% vs the S&P 500’s 20% (price basis) · median over 6 years
  • 3 years 66% vs the S&P 500’s 30% (price basis) · median over 4 years
  • 5 years 116% vs the S&P 500’s 84% (price basis) · median over 3 years

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 GWW

Does W.W. Grainger, Inc. have an economic moat?
Based on its FY2025 SEC filings, the Moat Index scores W.W. Grainger, Inc. (GWW) 89.8 out of 100 — a Wide 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 92, pricing power 66, returns on capital 100, balance-sheet safety 91, capital allocation 100.
Is GWW trading below the conservative owner-earnings estimate?
The value if growth stopped today — a zero-growth baseline — is $400.13 per share. It capitalizes normalized owner earnings at a 9% rate and assumes 0% growth. Versus a recent price of $1330.62, that is 233% 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 GWW's Moat Score changed over time?
The record logs 28 readings since Jul 17, 2026; the latest reads 89.8 out of 100 (wide 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.) The history is append-only — readings are only ever added, never rewritten.
