Armstrong World Industries (AWI): analysis traps
Where its figures could mislead a reader, and what to check before taking them at face value · Data: Q3 2026, to Sep 30, 2026, filed Oct 27, 2026; rules v1.1
Armstrong World Industries (AWI): 0 rules of 10 triggered on the filings to Sep 30, 2026. 1 to review; 1 with insufficient data; 2 not applicable. Each is a question to verify, with the normal explanation that would produce the same figures.
Check these first
A precise DCF value = the true value To review · confidence high
The DCF's point value is 140.62 a share (price 171.23); 74% of it is the terminal value, a number about years no one has seen. Moving revenue growth (each year) by ±5 pts alone takes it from 112.60 to 174.06; across every method the research ran the range is 46 to 377. The value is a range; the decimals are not information.
Innocent reading: A stable, mature business with a narrow range of outcomes, where the point value is a fair summary.
Every rule
A01 FCF growth = the business improved Not triggered confidence medium
Free cash flow rose $62M to $246M; working capital and lower capex explain 15% of it, so most of the gain is in operating cash flow itself.

| Operating cash flow before working capital: change | 79100000.00 |
FCF = operating cash flow − cash capex; ΔFCF = ΔOCF − ΔCapEx; the working-capital part is the change in the cash-bridge items (receivables, inventory, payables, accruals), with the sign of the cash flow statement

A07 Stock compensation added back = no economic cost Not triggered confidence high
Stock compensation is 1.4% of revenue: small enough that adding it back changes little.

B02 Receivables growing = future cash is certain Not triggered confidence medium
Receivables grew 19% against revenue 12% in Q3 2026; DSO 36 against a median of 34: collections are keeping pace with sales.
The figures and how they are read
| Quarter | Q3 2026 |

receivables and revenue against the same quarter a year earlier; DSO = receivables / quarterly revenue × days, against the median of the eight quarters before
Source: Q3 2026 (receivables and revenue) · Q3 2025 (the same quarter a year earlier)
B08 Adjusted profit = economic profit Insufficient data
no reconciliation table read from the releases yet and fewer than three quarters with both an adjusted and a GAAP EPS
C02 Low net debt = no refinancing risk Not triggered confidence medium
$10M comes due within a year, 28.1× covered by cash and investments of $71M plus $218M of free cash flow.

D03 EPS growth = profit growth Not triggered confidence high
EPS rose 10% and net income rose 6% in Q3 2026; the share count fell 3.0%: EPS growth follows profit growth.

E02 Low P/E at a cyclical peak = undervalued Not triggered confidence medium
Net income of $321M is a high, but the last eight years rose almost every year (median $214M): a steady climb, not a cycle's top, so the P/E of 22.6× is not on peak profit in that sense.
The figures and how they are read
| market value | $7.2B |
| net income ttm | $321M |
| pe ttm | 22.60 |
| net income median fy | $214M |
| pe mid cycle | 33.80 |
| net income peak fy | $309M |
| years | FY2018 / 186.0; FY2019 / 214.0; FY2020 / -99.0; FY2021 / 183.0; FY2022 / 203.0; FY2023 / 224.0; FY2024 / 265.0; FY2025 / 309.0 |
| down years in window | 1 |
P/E on the trailing twelve months' net income against the P/E on the median net income of the last eight fiscal years (a mid-cycle stand-in); 'at a peak' = this year's profit at or above 90% of the best year and at least 1.3× the median

E07 A precise DCF value = the true value To review confidence high
The DCF's point value is 140.62 a share (price 171.23); 74% of it is the terminal value, a number about years no one has seen. Moving revenue growth (each year) by ±5 pts alone takes it from 112.60 to 174.06; across every method the research ran the range is 46 to 377. The value is a range; the decimals are not information.
The figures and how they are read
| dcf value | 140.62 |
| price | 171.23 |
| terminal value share | +74.2% |
| swing by input | Revenue growth (each year) / ±5 pts / 112.6 / 174.06; WACC / ±1 pt / 119.6 / 169.88; Operating margin / ±3 pts / 123.17 / 158.06; Tax rate / ±5 pts / 130.68 / 150.56 |
| range all methods | 46.22; 376.9 |
the DCF's point value against the share of it that is the terminal value and the value at each input moved by one step (growth ±5 pts, WACC ±1 pt, margin ±3 pts …); the range across every method the research ran

What would explain it innocently
- A stable, mature business with a narrow range of outcomes, where the point value is a fair summary
- The inputs that matter most are themselves well known (a regulated return, a long contract)
What to look for in the filing
- Which input you believe differs from the research's and why
- What the price implies for growth (the reverse DCF on the fair-value page)
What would show the trap does not apply
- The DCF's value is robust to the terminal growth and discount rate (the range's low end is still above the price)
- The company's cash flows over the next three years track the DCF's early years
Look again: next filing.
J06 A bank's low P/E and high profit = safe Not applicable
not a bank
J08 A REIT's low net income = the dividend is unsafe Not applicable
not a REIT
What the statuses mean
Triggered: the filings show the pattern; read the normal explanations and the missing evidence before concluding anything. To review: one quarter or a weak signal; a reader's judgement, not a pattern. Not triggered: the pattern is absent on these figures. Insufficient data: the filings read so far do not hold what the rule needs; this is not a clean bill. Not applicable: the rule is not meant for this kind of company (a bank's working capital, a loss-making quarter's EPS growth). Out of date: the latest filing is more than fifteen months old.
Severity is what the pattern could mean for cash, value or solvency; confidence is how reliable the inputs and the reading are. The two are kept apart.

Every rule and the companies it triggers on → Armstrong World Industries: cash flow → Earnings quality score →
Each rule reads the company's own filings by a fixed formula and says what would explain the same figures innocently. A triggered rule is a question to verify, not a finding of manipulation, and not a view on the stock. Missing data is shown as missing, never as clear. Not investment advice.
