The figures above are taken directly from filings with the U.S. Securities and Exchange Commission. The reading below was generated by a local language model from only those figures; it introduces no numbers of its own. It is not investment advice.
Lennox International Inc. (LII) operates in the heating, ventilation, and air conditioning (HVAC) industry, as evidenced by its substantial revenue scale of $5.20B for the year ending 2025-12-31. The company’s multi-year trajectory reveals a steady growth pattern in revenue, increasing from $3.44B in 2008 to $5.20B in 2025—a 2.5% annual pace over 17 years. This consistent expansion underscores the company’s market presence and demand for its HVAC solutions.
Notably, LII has also demonstrated a significant improvement in net margin, which expanded from 3.6% to 15.5% during this period. This indicates enhanced operational efficiency and profitability over time. In terms of financial health, the company maintains a solid asset base of $4.08B and total liabilities of $2.92B as of 2025-12-31, reflecting a manageable debt position relative to assets.

Additionally, observing any shifts in gross and operating margins will be crucial, as they may signal changes in production costs or competitive pressures within the HVAC sector. The company’s performance in managing cash flow—which has shown fluctuations between robust $757.6M annual figures and more modest quarterly amounts—will also warrant attention for insights into its liquidity and investment capacity.
