What matters now
- A fairly wide model range ($106.04 to $241.92) leaves room in how you read the outcome.
- The price sits in the lower half of our model range, the side with the larger margin of safety.
- Read the verdict with care: some models are missing inputs, so the estimate scatters more than usual.
Price vs Fair Value (5 years)
White line = price, green steps = our fair value per fiscal year, dashed = 300-day average. As of Sep 3, 2026.
How to read this chart
60‑month range $68.88 – $203.89 · fair‑value band $106.04 – $241.92 · the $134.71 price screens below the $153.33 fair value. Green steps = our fair value per fiscal year (point-in-time, no hindsight). 1 fiscal year is left out: there the valuation rested on only a fraction of the usual models. Dashed = 300-day average. As of Sep 3, 2026.
Analysis
Owens Corning Inc (OC) currently trades at $134.71, while our model-based Fair Value estimate is $153.33, implying the stock looks roughly 12.1% undervalued today. The Quality Score stands at 48/100 (below-average quality), in the Industrials sector. Bull case: the Multiples group reads highest at a median of $309.28 per share, and 10 of the 15 models we run sit above the $134.71 price. Bear case: the Asset-Based group reads lowest at $32.06, and 5 of the 15 models stay below the price. Evidence for this calculation is medium.
Over the trailing twelve months, Owens Corning Inc generated revenue of $9.8B at a net margin of −5.4%. Revenue declined 10.5% year over year. It earns a return on equity of −9.4%. Net debt stands at $5.8B. Fundamentals as of Sep 3, 2026
Our scenario range runs from $106.04 (bear case) to $241.92 (bull case); at $134.71, the current price sits within that range. Bear and bull are the same models run on conservative and optimistic assumptions (margins, growth, valuation multiples), so a plausible valuation range, not a price target. The share trades about 14% below its 52-week high and 40% above its 52-week low, currently above its 200-day average. For context, the median of 10 Industrials peers we cover trades at −29% fair-value upside, at 14%, OC screens cheaper than that median.
Fair Value models
Each model estimates fair value its own way; the Fair Value above is the evidence-weighted, family-balanced blend. Evidence (0–100) measures how completely this model’s inputs are available: well-fed models carry more weight in the blend. The spread across models is intentional, each one stresses a different value driver; dividend models, for instance, come out structurally low when payout is small. Every input is real reported data, nothing guessed.
All 15 models by family
Widest divergence: Multiples ($309.28) versus Asset-Based ($32.06). Highest evidence: FCF DCF (78).

Quality Score breakdown
Of which business quality 47 · Market factors (momentum, volatility) 48
Non-valuation factor families (profitability, growth, cashflow, financial strength, momentum …), each academically grounded. Valuation itself sits in the Fair Value and is deliberately excluded here to avoid double-counting.
All values are scores from 0 to 100 (100 = best against fixed, research-based bands), not percentages. The three market factors (momentum, 52-week proximity, low volatility) are displayed but carry zero weight in the headline number: market sentiment is not a business property.
