Is BY overvalued in 2026?
Byline Bancorp Inc (BY) currently trades at $32.40 per share with a market capitalization of $1,471,581,000.00. Based on our multi-factor framework, the stock trades at a fair valuation with a Smart Value Score of 66/100. 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 10.5x, above its 5-year median of 10.1x.
Looking at its own history, BY is currently trading more expensive than 60% of the last 5Y on P/E. This places it in the 60th percentile of its historical range, a reasonable but unremarkable position.
A standard DCF model does not produce reliable output for BY 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.
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: BY trades at a fair valuation on our framework, with a Smart Value Score of 66/100. The valuation is defensible but offers no obvious bargain. Patience or a better entry price may reward disciplined buyers.
