What today’s price assumes: owner earnings growing ~23%/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 243% above the zero-growth estimate across 49 of the current top 50 companies by Moat Score with both values.
Missing a usable price or zero-growth estimate: ANF.

18 years of fundamentals
The business, in plain English
ARMSTRONG WORLD INDUSTRIES, INC. booked $1.6B of revenue in FY2025 in the Materials sector and kept 40.6% of it as gross profit — a solid-margin business by that measure. After every other cost, 19.0% of each revenue dollar reached the bottom line.
Across the filed record, revenue shrank from $2.8B (FY2009) to $1.6B (FY2025) — about −3.3% a year compounded over 16 years.
It earned 27.8% on invested capital in the latest filed year, FY2025. Across the full 17-year measurable filed record, median ROIC was 18.9%. Over the v3 recent window (10 measurable filed years), median ROIC was 22.2%. The Returns on Capital filter above scores it 100/100.
The balance sheet carried $407M of total debt in FY2025 against $320M of owner earnings — roughly 1.3 years of owner earnings to retire it all. Balance-Sheet Safety scores it 75/100.
Put together: Business Trend is the strongest of the five filters (100/100) and Pricing Power the weakest (61/100), which is how AWI lands at 87/100 — a Wide moat.

How ARMSTRONG WORLD INDUSTRIES, INC. makes its money
Start with a dollar of revenue and follow what the filing says remains.
Honest partial: the filing did not provide a normalized tag for Research and development, Selling, general and administrative; those components are omitted, not plugged.
Position size uses shares and filed value from each manager’s 13F. Portfolio weight uses the eligible long-share filing denominator. Changes compare only with the immediately preceding calendar quarter.

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.

Among the rows shown, A/F/M acquisition, payment or withholding, and exercise or conversion rows outnumber S sale rows (2 versus 0). 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.

How ARMSTRONG WORLD INDUSTRIES, 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 AWI 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 1 year AWI rated Wide-moat (2025), the median forward total return that followed — measured only after each year’s filings were public — was:
1 yearNone of the 1 year it rated Wide has a fully elapsed 1-year window with a benchmark to compare against yet.
3 yearsNone of the 1 year it rated Wide has a fully elapsed 3-year window with a benchmark to compare against yet.
5 yearsNone of the 1 year 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.

Does ARMSTRONG WORLD INDUSTRIES, INC. have an economic moat?
Based on its FY2025 SEC filings, the Moat Index scores ARMSTRONG WORLD INDUSTRIES, INC. (AWI) 87.2 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 100, pricing power 61, returns on capital 100, balance-sheet safety 75, capital allocation 100.
Is AWI trading below the conservative owner-earnings estimate?
The value if growth stopped today — a zero-growth baseline — is $59.34 per share. It capitalizes normalized owner earnings at a 9% rate and assumes 0% growth. Versus a recent price of $168.16, that is 183% 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 AWI's Moat Score changed over time?
The record logs 30 readings since Jul 17, 2026; the latest reads 87.2 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.
