Lennox International LII
Lennox International scores average on business quality (4.8 of 10). Here is why, in plain words, and what our sealed record shows.
Why it matters
- 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.
- 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.
- 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.
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.
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.
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.
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.
