Revenue $1.4 billion, down 5%
GAAP Operating Income $310 million – Segment profit up 2% to $310 million
GAAP diluted EPS $6.98 – Adjusted diluted EPS up 4% to $6.98
FY 25 guidance updated – Revenue down ~1% and revised adjusted EPS range of $22.75 to $23.25

DALLAS, Oct. 22, 2025 /PRNewswire/ -- Lennox (NYSE:LII), a leader in energy-efficient climate-control solutions, today reported third quarter financial results with $1.4 billion of revenue, $310 million of operating income, and $6.98 GAAP diluted earnings per share.

Revenue declined 5% to $1.4 billion. Segment profit increased 2% to $310 million. Segment margin was up 150 basis points to 21.7%. Adjusted diluted earnings per share increased 4% to $6.98.

"As anticipated, 2025 is proving to be a transitional year, shaped by the impact of the refrigerant transition and difficult macroeconomic conditions. During these uncertain times, the Lennox team continues to respond with agility and discipline, delivering margin expansion in both segments," said CEO, Alok Maskara. "The recent DuroDyne and Supco acquisition strengthens our parts and accessories portfolio, positioning us for greater success during the more normalized operating environment expected in 2026 and beyond. In light of ongoing industry volume pressures and consumer confidence trends, we believe it is prudent to update our full-year guidance to include an expected revenue decline of 1% and adjusted earnings per share from $22.75 to $23.25."

The Home Comfort Solutions segment revenue declined 12% in the third quarter, reflecting elevated channel destocking and a weak summer selling season. Recent regulatory transition and ongoing macroeconomic uncertainty continues to weigh on consumer and dealer sentiment, contributing to the shift toward repair over replacement. Despite these headwinds, segment profit margins expanded by 30 basis points, as cost reduction initiatives and favorable mix/price offset the impact of lower volumes and cost inflation.

The Building Climate Solutions segment delivered 10% revenue growth in the third quarter, despite ongoing weakness in the light commercial industry, as higher manufacturing output and lower lead times supported emergency replacement demand. The segment also delivered double-digit revenue growth in commercial services and Heatcraft as investments in sales excellence started to generate results. Segment margins expanded by 330 basis points, as favorable mix, cost control initiatives, and pricing offset inflation. Margin improvements were also supported by increased factory efficiencies as production at our new Saltillo facility continued to scale.

THIRD QUARTER 2025 FINANCIAL HIGHLIGHTS

(All comparisons are year-over-year, unless otherwise noted)

Revenue: $1.4 billion was down 5% driven by unfavorable sales volumes.

Operating Income: $310 million, up 2%, with operating profit margin of 21.7%, up 150 basis points.

Segment Profit: $310 million, up 2%, and segment profit margin of 21.7%, up 150 basis points. Profit improvement can be attributed to $118 million of mix/price benefits, driven primarily by new product mix, and a $4 million improvement of other costs, including selling expense net of freight and distribution expense. This was partially offset by $85 million decrease in sales volumes; and $30 million of product cost primarily related to recent inflationary impacts.

Net Income: $246 million, or $6.98 per share, compared to $239 million, or $6.68 per share, in the prior-year quarter.

Adjusted Net Income: $246 million, or $6.98 per share, compared to $239 million, or $6.68 per share, in the prior-year quarter.

Cash Flow: Operating cash flow was $301 million compared to $452 million in the prior-year quarter as finished goods inventory levels are temporarily elevated. Net capital expenditures were $35 million compared to $40 million in the prior-year quarter. This quarter $37 million of shares were repurchased.

Home Comfort Solutions: Business segment revenue was $913 million, down 12%. Segment profit was $203 million, down 10%, and segment margin was 22.2%, up 30 basis points. Segment profit decreased $24 million compared to the prior-year quarter. The decline was driven by a $86 million contraction in sales volumes and $26 million in product cost inflation net of factory productivity. This was partially offset by $85 million in mix/price benefits and $3 million improvement of other costs, including selling expense net of freight and distribution expense.

Building Climate Solutions: Business segment revenue was $514 million, up 10%. Segment profit was $134 million, up $28 million or 27%, and segment margin improved 330 basis points to 26.1%. This increase was driven by $33 million in mix/price benefits and $1 million increase in sales volumes. This was partially offset by $4 million of product cost inflation net of factory productivity, and $2 million from investment in distribution and selling as well as other inflationary impacts.

Corporate and Other: Corporate expenses were $27 million, down $2 million from the prior-year quarter.

FULL YEAR 2025 GUIDANCE

For full year 2025, adjusted earnings per share is now expected to be within the range of $22.75 to $23.25.

Revenue is now anticipated to decrease by approximately 1%. We continue to expect pricing to offset the inflationary pressures.

Free cash flow guidance is now approximately $550 million, driven by temporarily elevated inventory levels.

FORWARD-LOOKING STATEMENTS & NON-GAAP FINANCIAL MEASURES

The statements in this document that are not historical statements, including statements regarding the 2025 full-year outlook and expected consolidated and segment financial results, as well as financial targets for future years, are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements are based on information currently available as well as management's assumptions and beliefs today. These statements are subject to numerous risks and uncertainties that could cause actual results to differ materially from the results expressed or implied by the statements, and investors should not place undue reliance on them. Risks and uncertainties that could cause actual results to differ materially from such statements include risks that the North American unitary HVAC and refrigeration markets perform worse than current assumptions. Additional risks include but are not limited to competition in the HVACR business; our ability to successfully develop and market new products or execute our business strategy; our ability to meet and anticipate customer demands; our ability to continue to license or enforce our intellectual property rights; our ability to attract, motivate, develop, and retain our employees, as well as labor relations problems; artificial intelligence technologies; a decline in new construction activity and related demand for our products and services; the impact of weather on our business; the impact of higher raw material prices and significant supply interruptions; product liability, warranty claims, or recalls; changes in environmental and climate-related legislation or government regulations or policies; changes in tax legislation; the impact of new or increased trade tariffs; improper conduct by any of our employees, agents, or business partners; litigation risks; general economic conditions in the United States and abroad; extraordinary events beyond our control; risks associated with our international operations; cyber-attacks and other disruptions or misuse of information systems; and our ability to successfully realize, complete and integrate acquisitions.

For information concerning these and other risks and uncertainties, see LII's publicly available filings with the Securities and Exchange Commission. LII disclaims any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.

A reconciliation of non-GAAP financial measures appearing in this document to financial measures prepared in accordance with U.S. Generally Accepted Accounting Principles (GAAP) are included in the Annex to this document.

This document includes forward-looking statements regarding segment profit, adjusted net income, adjusted diluted earnings per share, and free cash flow, which are non-GAAP financial measures. These non-GAAP financial measures are derived by excluding certain amounts from the corresponding financial measures determined in accordance with GAAP. The determination of the amounts excluded is a matter of management judgment and depends upon, among other factors, the nature of the underlying expense or income amounts recognized in a given period and the high variability of certain amounts, such as unusual gains and losses, the ultimate outcome of pending litigation, fluctuations in foreign currency exchange rates, changes in environmental liabilities, the impact and timing of potential acquisitions and divestitures, future restructuring costs, and other structural changes or their probable significance. We are unable to present a quantitative reconciliation of the aforementioned forward-looking non-GAAP financial measures to their most directly comparable forward-looking GAAP financial measures because such information is not available, and management cannot reliably predict the necessary components of such GAAP measures without unreasonable effort or expense. The unavailable information could have a significant impact on LII's full year GAAP financial results.
