, /PRNewswire/ –** Lennox (NYSE: LII),** a leader in energy-efficient climate-control solutions, today reported fourth quarter financial results with $1.2 billion of revenue, $196 million of operating income, and $4.07 GAAP diluted earnings per share. Accompanying financial tables reflect the change in accounting method resulting from the transition from LIFO to FIFO accounting.

Revenue declined 11% to $1.2 billion. Segment profit decreased 16% to $212 million. Segment margin was down 110 basis points to 17.7%. Adjusted diluted earnings per share decreased 22% to $4.45.

"We are pleased with our performance in 2025 given industry headwinds. For the first time in its history, Lennox delivered annual margins over 20%, a particularly meaningful accomplishment driven by our cost reduction actions and mix benefits," said CEO, Alok Maskara. "This is a direct reflection of the hard work and dedication of the Lennox team, and we remain confident that our strategy and recent investments position us to grow revenue and profits in 2026 as the industry normalizes."

Home Comfort Solutions revenue declined 21% in the fourth quarter, driven by expected channel destocking and continued softness in new construction sales. Broader macroeconomic uncertainty continued to temper both consumer and dealer activity which has led to an increase in deferred system replacements. Segment margins were down 220 basis points, primarily due to the impact of lower sales volumes and under absorption of manufacturing costs. In response to these headwinds, we took disciplined SG&A cost control actions and delivered favorable mix and price. We have a more constructive backdrop as we enter the new year with one–step channel’s inventory destock nearly complete and two-step inventories expected to normalize by the second quarter.

The Building Climate Solutions segment delivered 8% revenue growth in the fourth quarter, supported by steady parts acquisition, services demand, and a favorable mix. Margins expanded on improved factory productivity and disciplined cost control. Despite end markets below historical levels, the segment continued to gain momentum in emergency replacement positioning us for growth acceleration.

**FOURTH QUARTER 2025 FINANCIAL HIGHLIGHTS **(All comparisons are year-over-year, unless otherwise noted) (Reflects change in accounting method from LIFO to FIFO, effective 4Q 2025)

Revenue: $1.2 billion was down 11% driven by unfavorable sales volumes.

**Operating Income: **$196 million, down 22%, with operating profit margin of 16.4%, down 220 basis points.

Segment Profit: $212 million, down 16%, and segment profit margin of 17.7%, down 110 basis points primarily driven by $115 million decrease in sales volumes and $31 million product cost primarily related to recent inflationary impacts and factory under absorption. This was partially offset by $84 million of mix/price benefits and a $21 million improvement in SG&A and other costs.

Net Income: $143 million, or $4.07 per share, compared to $202 million, or $5.64 per share, in the prior-year quarter.

Adjusted Net Income: $155.8 million, or $4.45 per share, compared to $205 million, or $5.72 per share, in the prior-year quarter.

Cash Flow: Operating cash flow was $406 million compared to $332 million in the prior-year quarter as inventory levels normalized in the quarter. Net capital expenditures were $29 million compared to $60 million in the prior-year quarter. Share repurchases totaled $150 million.

Home Comfort Solutions: Business segment revenue was $700 million, down 21%. Segment profit was $137 million, down 29%, and segment margin was 19.6%, down 220 basis points. Segment profit decreased $56 million compared to the prior-year quarter. The decline was driven by a $102 million contraction in sales volumes, $29 million in product cost inflation and lower factory absorption. This was partially offset by $56 million in mix/price benefits and $19 million improvement of other costs, including selling expense net of freight and distribution expense.

Building Climate Solutions: Business segment revenue was $495 million, up 8%. Segment profit was $115 million, up $11 million or 11%, and segment margin improved 50 basis points to 23.1%. This increase was driven by $27 million in mix/price benefits and $5 million improvement in selling expenses, net of acquisition and other expenses. This was partially offset by $13 million decrease in sales volume; $5 million from higher distribution and freight costs; and $3 million in product cost inflation and lower factory absorption.

Corporate and Other: Corporate expenses were $40 million, down $4 million from the prior-year quarter.

**FULL YEAR 2025 FINANCIAL HIGHLIGHTS **(All comparisons are year-over-year, unless otherwise noted) (Reflects change in accounting method from LIFO to FIFO, effective 4Q 2025)

Revenue: $5.2 billion was down 3% driven by unfavorable sales volumes.

**Operating Income: **$1 billion, flat to prior-year, with operating profit margin of 20.0%, up 50 basis points.

Segment Profit: $1.1 billion, up 2%, and segment profit margin of 20.4%, up 90 basis points. Profit improvement can be attributed to $356 million of mix/price benefits, driven primarily by new product mix; and $56 million improvement in other costs, including selling expense. This was partially offset by $255 million decrease in sales volumes, $80 million of product cost primarily related to inflationary impacts, and $61 million of freight and distribution expense.

Net Income: $806 million, or $22.79 per share, compared to $811 million, or $22.66 per share, in the prior-year.

Adjusted Net Income: $819 million, or $23.16 per share, compared to $813 million, or $22.70 per share, in the prior-year.

Cash Flow: Operating cash flow was $757 million compared to $946 million in the prior-year, primarily driven by excess inventory associated with refrigerant transition dynamics, channel destocking, and the deployment of emergency replacement product. Net capital expenditures were $117 million compared to $161 million in the prior-year. Share repurchases totaled $482 million.

Home Comfort Solutions: Business segment revenue was $3.3 billion, down 7%. Segment profit was $729 million, down 4%, and segment margin was 21.8%, up 50 basis points. Segment profit decreased $32 million compared to the prior-year. The decline was driven by a $224 million contraction in sales volumes; $64 million in product cost inflation and factory productivity; and $47 million in freight and distribution expense. This was partially offset by $256 million in mix/price benefits and $47 million improvement of other costs, including selling expense.

Building Climate Solutions: Business segment revenue was $1.9 billion, up 5%. Segment profit was $434 million, up $33 million or 8%, and segment margin improved 60 basis points to 23.4%. This increase was driven by $100 million in mix/price benefits. This was partially offset by $31 million in lower sales volumes, $16 million of product cost inflation net of factory productivity and $20 million from investment in distribution and selling as well as other inflationary impacts.

Corporate and Other: Corporate expenses were $105 million, down $15 million from the prior-year.

**FULL YEAR 2026 GUIDANCE **For full year 2026, revenue is anticipated to increase by approximately 6% to 7%, with growth from completed acquisitions contributing approximately 4%.

Adjusted earnings per share is expected to be within the range of $23.50 to $25.00.

Capital expenditures are projected to be approximately $250 million, and Free Cash Flow is estimated to fall within the range of $750 million to $850 million.

**FORWARD-LOOKING STATEMENTS & NON-GAAP FINANCIAL MEASURES **The statements in this document that are not historical statements, including statements regarding the 2026 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.
