Is LII overvalued in 2026?
Lennox International Inc (LII) currently trades at $517.62 per share with a market capitalization of $18,018,308,000.00. Based on our multi-factor framework, the stock trades at a fair valuation with a Smart Value Score of 56/100. 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 23.0x, above its 5-year median of 22.6x. The PEG ratio of 1.42 points to a price that reasonably reflects expected earnings growth.
Looking at its own history, LII is currently trading more expensive than 58% of the last 5Y on P/E. This places it in the 58th percentile of its historical range, a reasonable but unremarkable position.
Our discounted cash flow model estimates LII's intrinsic value at $365.66 per share, against the current market price of $517.62. This implies a premium to fair value of -52.47%. 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: LII trades at a fair valuation on our framework, with a Smart Value Score of 56/100. The valuation is defensible but offers no obvious bargain. Patience or a better entry price may reward disciplined buyers.
