Analysis
Lennox International Inc (LII) currently trades at $418.31, while our model-based Fair Value estimate is $363.09, implying the stock looks roughly 13.2% overvalued today. The Quality Score stands at 65/100 (solid quality), in the Industrials sector. Bear case: priced above our estimate, the market already discounts strong expectations. Bull case: above-average quality can justify a premium, the entry price still matters most (evidence: high).
Over the trailing twelve months, Lennox International Inc generated revenue of $5.3B at a net margin of 15.1%. Revenue grew 5.8% year over year. It earns a return on equity of 76.8%. Net debt stands at $2.0B. Fundamentals as of Aug 13, 2026
Our scenario range runs from $194.25 (bear case) to $468.44 (bull case); at $418.31, the current price sits within that range. Bear and bull are the same models run on conservative and optimistic assumptions (margins, growth, valuation multiples), so a plausible valuation range, not a price target. The share trades about 39% below its 52-week high, currently below its 200-day average. For context, the median of 10 Industrials peers we cover trades at -60% fair-value upside, at -13%, LII screens cheaper than that median.
Fair Value models
Each model estimates fair value its own way; the Fair Value above is the evidence-weighted blend. Evidence (0–100) measures how completely this model’s inputs are available: well-fed models carry more weight in the blend. The spread across models is intentional, each one stresses a different value driver; dividend models, for instance, come out structurally low when payout is small.
All 25 models by family
