Frequently asked questions

Is LII growing its revenue and profit?

Over the past 5 years, Lennox International's revenue has grown 7.4% per year, and net income grown 17.7% per year. These are computed facts, not advice.

How much debt does LII have?

As of FY2025, Lennox International reported — of total debt against $34M of cash; operating income covered interest expense 25×.

What is LII's profit margin?

In FY2025, gross margin was 33.4%, operating margin 20.0%, and net margin 15.5%.

What is LII's P/E ratio?

Lennox International's P/E (TTM) is 16.14 as of the 2026-11-02 close — market cap ÷ net income over the trailing twelve months where four consecutive quarters are reported, otherwise the latest fiscal year, the same figure as on the LII stock page. The valuation chart above sets each month-end's price against the latest annual net income instead, so its latest point (about 15.0× as of Nov '26) can differ. These are computed facts, not advice.

Where does this data come from?

All figures are extracted from the company’s SEC EDGAR/XBRL filings — 10-K annual reports and 10-Q quarterly reports (use the Annual / Quarterly toggle). Quarterly figures are derived from the as-filed statements (year-to-date amounts are differenced into discrete quarters). Growth rates and ratios are computed by tradmap; nothing here is investment advice.
