Lennox Q3 2026 Earnings: Revenue Rose 10% as Margins Contracted

Lennox (NYSE: LII) reported Q3 2026 revenue of $1.57 billion, up 10% from $1.43 billion, while GAAP diluted EPS fell to $6.41 from $7.38. Adjusted diluted EPS declined 7% to $6.84 as competitive pressure, inflation, tariffs and lower factory absorption weighed on Home Comfort Solutions. Building Climate Solutions delivered 24% revenue growth and quarterly cash flow improved, but Lennox lowered its full-year adjusted EPS guidance.

Core Financial Results

Revenue growth came from organic expansion in Building Climate Solutions and completed acquisitions. However, gross profit increased only 2%, and operating income declined as costs grew faster than revenue.

Total segment profit was affected by a $45 million headwind from product cost inflation, including tariffs, and lower factory absorption. Higher fuel costs, SG&A and distribution inflation, and ongoing investments added pressure, partly offset by higher volumes, mix and price benefits, and acquisition contributions.

The 2025 comparative figures were adjusted to reflect Lennox’s change from LIFO to FIFO accounting in the fourth quarter of 2025.

Business and Segment Performance

Home Comfort Solutions generated $937.2 million of revenue, up 3%, but segment profit fell 18% to $175.7 million. Its margin contracted 490 basis points to 18.7%. Lower sales volumes created a $12 million profit headwind, while product cost inflation, tariffs and lower factory absorption reduced profit by another $32 million. Higher fuel, SG&A and distribution costs, and continued investment also weighed on results.

Lennox implemented targeted price adjustments in selected Home Comfort markets to defend and recover market share. Mix and pricing provided a $13 million benefit, while acquisitions added $6 million, but those gains were insufficient to offset the segment’s cost and volume pressures.

Building Climate Solutions performed differently. Revenue increased 24% to $635.3 million, including 15% organic growth, supported by commercial HVAC, refrigeration and services. Segment profit rose 19% to $166.5 million, although margin declined 110 basis points to 26.2% from the prior year’s record level.

Higher Building Climate sales volumes contributed $24 million to profit, mix and price added $8 million, and acquisitions contributed $13 million. Product cost inflation, tariffs and lower factory absorption created a $14 million headwind, while higher SG&A and distribution costs reduced profit by another $5 million.

Building Climate Growth Could Not Offset Home Comfort Margin Compression

The divergence between the two segments explains why consolidated revenue rose while earnings declined. Building Climate Solutions added approximately $121 million of revenue and $26 million of segment profit, but Home Comfort’s segment profit fell by about $40 million despite a modest increase in sales.

Lower corporate expenses provided an additional $8 million benefit, but this was not enough to prevent total segment profit, including corporate expenses, from declining by about $6 million. The result was a 240-basis-point contraction in total segment margin even as revenue increased 10%.

This pattern also shows the limits of acquisition-driven and commercial-market growth when the larger Home Comfort business faces price competition and cost inflation at the same time. Management’s ability to improve cost pass-through, restore residential market share and raise factory utilization will be central to recovering consolidated margins.

Profitability, Cash Flow and the Balance Sheet

Gross profit rose by only $10 million on a roughly $146 million increase in revenue. Based on the reported figures, gross margin declined to approximately 31.6% from 34.1%. SG&A expense also increased to $177.3 million from $161.6 million, while Lennox recorded $8.2 million of restructuring charges.

Higher costs below operating income further affected GAAP earnings. Net interest expense increased to $17.5 million from $10.5 million, and the income tax provision rose to $72.1 million from $57.5 million despite lower pretax income. Adjusted net income was $235.9 million after excluding restructuring, acquisition, litigation and disposition-related items.

Cash generation was stronger than reported earnings. Operating cash flow increased to $395.3 million, which management attributed to reduced inventory levels, while quarterly capital spending was $33.2 million. Free cash flow consequently increased to $362.7 million, and Lennox repurchased $151 million of shares during the quarter.

For the first nine months of 2026, Lennox generated $461.0 million of free cash flow. Over the same period, it spent $209.9 million on acquisitions, $301.9 million on share repurchases and $137.5 million on dividends. At September 30, cash and cash equivalents were $43.3 million, while commercial paper, current debt maturities and long-term debt totaled approximately $1.62 billion, compared with about $1.39 billion at the end of 2025.

Full-Year Guidance

Lennox revised its full-year revenue growth outlook to approximately 6%, including a 5% benefit from completed acquisitions. More significantly, it lowered adjusted EPS guidance to $21.00-$21.50 from $23.00-$24.00, consistent with the margin pressures reported in the third quarter. Free cash flow guidance was updated to $700 million-$750 million.

The release did not state the previous revenue growth or free cash flow ranges. Based on nine-month adjusted EPS of $17.89, the latest outlook implies approximately $3.11-$3.61 of adjusted EPS in the fourth quarter. The free cash flow outlook implies roughly $239 million-$289 million in fourth-quarter free cash flow after the $461 million generated through September.

Management continues to expect full-year Building Climate Solutions margins to expand despite inflation and tariff pressure. Priorities for Home Comfort include addressing market-share challenges, improving productivity, mitigating tariffs and introducing new entry-tier products.

Recent Insider Transactions

The supplied insider data shows 12,722 shares acquired across 10 transactions and 971 shares sold in one transaction over the latest six-month period, resulting in a net increase of 11,751 shares. The most recent individual records were primarily director stock awards and gifts priced at $0; the period’s sole reported sale was by Chris A. Kosel.

The transaction data alone does not establish insiders’ views about Lennox’s operating outlook or valuation.

Risks Investors Need to Watch

• Home Comfort competition: Targeted price adjustments may help defend market share, but they can also make it harder to recover inflation and tariff costs, prolonging margin pressure.
• Cost pass-through and productivity: Product inflation, tariffs, fuel expenses and lower factory absorption affected Q3 profit. The updated outlook depends partly on Lennox improving pricing processes and accelerating productivity initiatives.
• Building Climate margin durability: The segment’s revenue and profit grew, but its margin still declined 110 basis points. Persistent cost pressure could challenge management’s expectation for full-year margin expansion.
• Acquisition and financing exposure: Completed acquisitions account for most of the guided 2026 revenue growth benefit. Acquisition spending, higher reported debt and increased interest expense raise the importance of successful integration and continued cash generation.
• Fourth-quarter execution: The reduced EPS range and updated free cash flow target still require meaningful fourth-quarter earnings and cash generation, making pricing, inventory management and cost control important near-term indicators.

Summary

Lennox’s Q3 2026 results combined double-digit revenue growth and stronger cash flow with lower earnings and substantially weaker margins. Building Climate Solutions remained the primary growth engine, but its gains could not fully offset Home Comfort’s volume, pricing and cost challenges. The lowered adjusted EPS outlook shifts attention to whether Lennox can improve cost recovery, productivity and residential market-share performance while sustaining Building Climate growth and meeting its fourth-quarter cash flow requirements.
