Is GBX overvalued in 2026?
Greenbrier Companies Inc (GBX) currently trades at $47.80 per share with a market capitalization of $1,478,865,000.00. Based on our multi-factor framework, the stock trades at a fair valuation with a Smart Value Score of 54/100. 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 10.2x, below its 5-year median of 11.9x. The PEG ratio of 0.58 suggests earnings growth is outpacing the multiple, a classic sign of undervaluation.
Looking at its own history, GBX is currently trading cheaper than 76% of the last 5Y on P/E. This places it in the 24th percentile of its historical range, a level that has historically coincided with attractive entry points.
Our discounted cash flow model estimates GBX's intrinsic value at $79.06 per share, against the current market price of $47.80. This implies a margin of safety of +30.39%. A meaningful cushion exists against model error, making this a reasonable risk-adjusted entry.
Financial quality is a concern. The Piotroski F-Score of 0/9 flags weakening fundamentals that deserve closer scrutiny before the valuation case can be fully trusted.
Bottom line: GBX trades at a fair valuation on our framework, with a Smart Value Score of 54/100. The valuation is defensible but offers no obvious bargain. Patience or a better entry price may reward disciplined buyers.
