Why it matters

  1. What Lennox International does

    Lennox International designs, manufactures, and markets climate control solutions, generating revenue primarily from heating, ventilation, air conditioning, and refrigeration equipment sold to contractors and building owners.

  2. What it does best

    Lennox delivers elite return on equity of 66.9%, outperforming peers like CARR at 8.9% and MAS at 279.8% while maintaining tighter capital discipline. This efficiency stems from a deeply integrated dealer network that locks in installers.

  3. The main risk

    Revenue contraction of 2.7% highlights top-line vulnerability. If demand for residential and commercial HVAC units drops further, factory utilization falls and pressures the 20.2% operating margin.

Quality, check by check

Scored against its own industry, from company filings.

ProfitabilityStrong

Operating margin stands at 20.2% and FCF margin at 13.9%, ranking in the top quartile of its sector. Strong pricing power and manufacturing efficiency drive these margins, letting the business extract high cash flow as it scales.

MoatFair

A top-quartile operating margin of 20.2% and top-decile ROE of 67.0% reflect a strong dealer-distribution moat that locks in contractors through specialized training and localized service.

GrowthSlow

Revenue declined 2.7% to $5.3B over the latest period, reversing prior gains and dropping growth to the 13th sector percentile as top-line momentum fades.

Financial healthFair

Debt-to-equity sits at 1.2 with total debt of $1.4B against $35M in cash, leaving a net debt position of $1.4B. Free cash flow reached $739M, signaling solid cash conversion despite a softer balance sheet.
