Operating margin widened by 0.6 percentage points between fiscal 2024 and 2025, which separates pricing and cost discipline from revenue growth alone. Free cash flow (operating cash flow minus capital expenditures) was $639 million against net income of $806 million; cash generation fell short of reported earnings, which is worth reconciling in the cash flow statement.

Where These Numbers Come From
Every figure on this page is a value Lennox International reported in its own SEC filings, read from the SEC's XBRL data (accession 0001069202-26-000028 for fiscal year 2025). Ratios are computed from those reported values. Figures were retrieved on October 12, 2026; a later amendment or a new annual report can change them, and the filing itself always takes precedence over this summary.
Each fiscal year is labeled by the calendar year in which it ended, so a company that names the same period differently in its own filings (many retailers whose year ends in January) may use another label. A year is left out of the table when the SEC data set holds no value for it. A figure shown as "Not reported" means the company did not file a value under the standard tag Swoopr reads, not that the amount was zero. This page is educational and describes reported history only; it is not a forecast or a recommendation.
