Armstrong World Industries, Inc. (AWI): fair value, margin of safety and Wheel Score
Ticker symbol AWI · Basic Materials · Construction Materials · United States · Growth
Is AWI undervalued?
Armstrong World Industries, Inc. (AWI) closed at 175.95 on 5 Nov 2026, 11% above the GLS average fair value of 158.48. Only 3 of the 9 models that produced a number value the shares above the current price. The margin of safety is negative, so the stock fails the "below fair value" Wheel Trade Filter; a premium of this size is common for companies whose growth the models are conservative about.
There is a wide gap between DDM (20.45) and GLS Growth (380.11). When the models are this far apart the "fair value" is really a range, and the margin of safety above should be read with that range in mind.
Ranked against every other company we cover, AWI is clearly faster-growing than it is cheap, so the nightly engine files it under Growth (value score 24, growth score 67, out of 100).

Quality and financial health
Armstrong World Industries, Inc. scores 6 of 9 on the Piotroski F-score: a middling result that passes the "Piotroski 6 or more" Wheel Trade Filter. Some of the nine tests on profitability, leverage and efficiency are failed, so the accounts are worth a look before selling a put on the name. A GLS Moat score of 7.6/10 puts AWI among the more durable businesses we track: over up to ten years its returns on capital have stayed high, its margins steady and its balance sheet sound.
Returns on capital are high - ROIC 21.5%, ROE 34.3%, ROA 16.0% - with debt at 0.59 times equity and a free-cash-flow yield of 3.1%.
The dividend yield is 0.79% with a payout ratio of 18% - a small yield that leaves most of the earnings in the business. Revenue comes mainly from Mineral Fiber 61%, Architectural Specialties 39% (quarter Q3 FY2026).
Institutional ownership scores 10/10, insider activity 10/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 6 / 9 | ROIC | 21.5% |
|---|---|---|---|
| GLS Moat | 7.6 / 10 | ROE | 34.3% |
| Debt / equity | 0.59 | ROA | 16.0% |
| Free-cash-flow yield | 3.1% | Payout ratio | 18% |
| Institutions | 10 / 10 | Insiders · Congress | 10 · 5 / 10 |
Wheel Score 29: Weak
With a Wheel Score of 29 Armstrong World Industries, Inc. sits in the Weak band. It fails filter 3, below fair value - trades 11% above our fair value; Value (weak) is its weakest part.
Implied volatility is 28% on the near-the-money contracts 20-60 days out: enough to pass the 25-80% Wheel Trade Filter, but under the 35-60% sweet spot the score rewards most. Chain open interest is 5,321 contracts across all expiries - enough for the wheel at normal size.
Volume runs at 500k shares a day on a market cap of $7.4B, with a beta of 1.14; the Stability part of the Wheel Score rates that good.

| 5 | Can repay its debt | Passes | Long-term debt repaid from 3 years of operating cash flow or less (6 for real estate and utilities; banks and insurers are not judged on it) |
| 6 | No serious red flags | Passes | Red Flags score 60 or more out of 100 (earnings, margins, debt, analysts, filings and price checked the same way for every stock) |
| 7 | A premium worth selling | Passes | Implied volatility 25-80% (enough premium, not a lottery ticket) |
| 8 | Big enough | Passes | Market cap $1 billion or more |
