Is ROCK overvalued in 2026?
Gibraltar Industries Inc (ROCK) currently trades at $37.53 per share with a market capitalization of $1,113,175,000.00. Based on our multi-factor framework, the stock trades at a fair valuation with a Smart Value Score of 55/100. This score blends growth quality, financial health, and price attractiveness into a single institutional-grade read.
The stock trades at a P/E ratio of 11.6x, below its 5-year median of 17.5x. The PEG ratio of 0.65 suggests earnings growth is outpacing the multiple, a classic sign of undervaluation.
Looking at its own history, ROCK is currently trading cheaper than 96% of the last 5Y on P/E. This places it in the 4th percentile of its historical range, a level that has historically coincided with attractive entry points.
Our discounted cash flow model estimates ROCK's intrinsic value at $38.21 per share, against the current market price of $37.53. This implies a premium to fair value of -41.64%. The current price sits well above what projected cash flows justify, implying investors are paying for growth that has not yet materialized.
Financial quality is a concern. The Piotroski F-Score of 3/9 flags weakening fundamentals that deserve closer scrutiny before the valuation case can be fully trusted.
Bottom line: ROCK trades at a fair valuation on our framework, with a Smart Value Score of 55/100. The valuation is defensible but offers no obvious bargain. Patience or a better entry price may reward disciplined buyers.
