Is GFF overvalued in 2026?
Griffon Corporation (GFF) currently trades at $88.63 per share with a market capitalization of $4,128,312,000.00. 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 87.8x, above its 5-year median of 28.3x. The PEG ratio of 0.54 suggests earnings growth is outpacing the multiple, a classic sign of undervaluation.
Looking at its own history, GFF is currently trading more expensive than 90% of the last 5Y on P/E. This places it in the 90th percentile of its historical range, a zone where forward returns have typically been muted.
A standard DCF model does not produce reliable output for GFF under current conditions. For unprofitable or near-breakeven companies, revenue-based multiples such as EV/Sales and historical P/S percentile are more informative than intrinsic value calculations.
The Piotroski F-Score of 5/9 puts financial quality in a middling range, neither a standout strength nor an obvious red flag.
Bottom line: GFF 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.
