Is OC overvalued in 2026?
Owens Corning Inc (OC) currently trades at $121.18 per share with a market capitalization of $9,740,833,000.00. Based on our multi-factor framework, the stock trades at a fair valuation with a Smart Value Score of 51/100. This score blends growth quality, financial health, and price attractiveness into a single institutional-grade read.
OC currently has no meaningful P/E ratio, which typically signals that the company is unprofitable, near breakeven, or emerging from a loss-making period. With a P/S ratio of 1.0x, the market is valuing the company primarily on its revenue rather than its earnings.
Looking at its own history, OC is currently trading cheaper than 100% of the last 5Y on P/E. This places it in the 0th percentile of its historical range, a level that has historically coincided with attractive entry points.
Our discounted cash flow model estimates OC's intrinsic value at $307.93 per share, against the current market price of $121.18. This implies a margin of safety of +55.04%. A meaningful cushion exists against model error, making this a reasonable risk-adjusted entry.
Financial quality is a concern. The Piotroski F-Score of 2/9 flags weakening fundamentals that deserve closer scrutiny before the valuation case can be fully trusted.
Bottom line: OC trades at a fair valuation on our framework, with a Smart Value Score of 51/100. The valuation is defensible but offers no obvious bargain. Patience or a better entry price may reward disciplined buyers.
