The five investor questions
2021–2025 (latest 5 aligned FYs; v3 window cap 5): revenue $1.1B to $1.6B, increasing; diluted EPS 3.82 to 7.08, increasing.
Median gross margin 36.7% over 10y, very stable.
Median ROIC 22.2%, above the 12% hurdle in 100% of years.
Net debt/EBITDA 0.5x, interest coverage 13x.
Owner earnings changed +13.2%/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.
- $229M
- $59.34
- $59.34
- $160.71
- 171% above value if growth stopped today
What today’s price assumes: owner earnings growing ~22%/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.
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 0% (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.
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.

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.
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.
Gaps in a line mean that item isn’t in AWI’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.

Scores are logged append-only and never overwritten — this record cannot be reconstructed retroactively, which is exactly why it’s worth keeping.
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.
The insider-filing service is temporarily unavailable, so no partial or guessed answer is shown for AWI.

- Is AWI trading below the conservative owner-earnings estimate?
