The Company's Resilient Business Model
Lennox International Inc (LII) is a global leader in energy-efficient climate control solutions, proudly designing, manufacturing, and marketing a broad range of products for the heating, ventilation, air conditioning, and refrigeration (HVACR) markets. With a rich history dating back to 1895, Lennox has leveraged its expertise to become an industry titan known for innovation, quality, and reliability.
Lennox operates in two reportable business segments: Home Comfort Solutions and Building Climate Solutions. The Home Comfort Solutions segment manufactures and markets a diverse range of furnaces, air conditioners, heat pumps, packaged heating and cooling systems, indoor air quality equipment, comfort control products, replacement parts, and supplies for the residential replacement and new construction markets in North America. The Building Climate Solutions segment produces and sells unitary heating and cooling equipment, applied systems, controls, and commercial refrigeration products, as well as provides installation and service for commercial HVAC national account customers in the United States and Canada.
This diversified business model has enabled Lennox to navigate various market conditions and deliver consistent financial performance. In 2024, the Company reported record revenue of $5.34 billion, a 7% increase from the prior year. Net income for the full year reached $806.9 million, with diluted earnings per share of $22.54. Lennox's operating cash flow and free cash flow also reached new highs of $946 million and $785 million, respectively, demonstrating the strength and resilience of its business.
The company's journey began in 1895 in Marshalltown, Iowa, where Dave Lennox, the owner of a machine repair business for railroads, founded the company. Lennox designed and patented a riveted steel coal-fired furnace, which laid the foundation for numerous advancements in heating, cooling, and climate control solutions over the years. This innovative spirit has remained a core part of Lennox's DNA, driving its growth and success in the HVACR industry.
In the late 1990s, Lennox demonstrated its adaptability by adopting the FIFO (First-In-First-Out) cost method for new domestic manufacturing operations, while existing operations continued to use the LIFO (Last-In-First-Out) cost method. This strategic decision allowed Lennox to better manage inventory costs and improve its financial performance.
More recently, in 2023, Lennox completed the divestiture of its European operations, which had previously been reported under the Corporate and Other segment. This strategic move allowed the company to focus on its core North American business segments, streamlining operations and enhancing overall efficiency. The transition was executed successfully, without any material adverse impacts on Lennox's financial condition or results of operations.
Driving Growth Through Strategic Initiatives
Lennox's success is underpinned by its disciplined execution of a multi-faceted growth strategy. The Company has consistently invested in research and development to drive technological innovation, enabling it to introduce industry-leading products that meet evolving customer needs. For example, in 2025, Lennox debuted its highly efficient SL22KLV Cold Climate Heat Pump, designed to deliver reliable comfort in temperatures as low as -20°F with efficiency levels 150% higher than standard heat pumps.
Furthermore, Lennox has strategically expanded its distribution channels and sales force to enhance customer accessibility and experience. The Company's network of Lennox Stores across the United States and Canada provides contractors and independent dealers with convenient access to universal service and replacement parts, supplies, and equipment. Additionally, Lennox's National Account Services division delivers installation, service, and preventive maintenance solutions for commercial HVAC customers nationwide.
Bolstering Growth Through Strategic Acquisitions
Lennox has also leveraged strategic acquisitions to drive inorganic growth and strengthen its competitive position. In 2023, the Company completed the acquisition of AES Industries, a leading provider of HVAC recycling and salvage services, as well as curbs, curb adapters, and drop box diffusers. This transaction has already exceeded Lennox's original value proposition, with the AES integration progressing ahead of schedule.
Additionally, in 2024, Lennox formed a joint venture with global electronics giant Samsung to distribute ductless air conditioning and heat pump products in the United States and Canada. This collaboration has allowed Lennox to expand its product portfolio and capitalize on the growing demand for energy-efficient HVAC solutions.
Navigating Market Dynamics and Regulatory Changes
The HVACR industry is subject to various market dynamics and regulatory changes, which Lennox has navigated adeptly. For instance, the ongoing transition to low-global warming potential (GWP) refrigerants has presented both challenges and opportunities for the Company. Lennox has strategically managed this transition, delaying the switch to new refrigerants to maintain product availability and capture temporary market share gains when competitors faced supply constraints.
Moreover, Lennox has demonstrated its ability to adapt to evolving trade policies and tariff regimes. The Company has reduced its reliance on China-sourced components, diversifying its supply chain to lessen the impact of potential trade barriers. Lennox has also effectively passed on cost increases to customers through strategic pricing initiatives, preserving its profitability.
Financial Strength and Disciplined Capital Allocation
Lennox's financial position remains robust, with a strong balance sheet and ample liquidity to support its growth initiatives. As of December 31, 2024, the Company had $415.1 million in cash and cash equivalents and a net debt to adjusted EBITDA ratio of 0.6x, down from 1.3x in the prior year quarter.
Lennox's disciplined capital allocation strategy has also contributed to its success. The Company prioritizes high-return organic investments, selectively pursuing strategic acquisitions that deliver ROIC exceeding the weighted average cost of capital within three years. Lennox also maintains an active share repurchase program, returning excess cash to shareholders and enhancing long-term value creation.
Financials
In 2024, Lennox reported record revenue of $5.34 billion, representing a 7% increase from the previous year. Net income for the full year reached $806.9 million, with diluted earnings per share of $22.54. The Company's operating cash flow and free cash flow also achieved new highs of $946 million and $782 million, respectively, showcasing the strength and resilience of its business model.
For the most recent quarter (Q4 2024), Lennox reported revenue of $1.35 billion, up 16.5% year-over-year. Net income for the quarter was $197.7 million, with operating cash flow of $332 million and free cash flow of $273 million, up 50% year-over-year. The strong revenue growth in Q4 was driven by a 22% increase in core revenue, including 1% from acquisitions. The company was able to effectively manage the refrigerant transition, leading to notable volume gains.
In terms of segment performance, the Home Comfort Solutions segment generated $3.58 billion in net sales in 2024, an 11% increase compared to 2023, driven by favorable price and mix as well as higher sales volumes. Segment profit increased by $149.5 million or 25% compared to 2023, primarily due to higher price, favorable mix, and increased sales volumes, partially offset by higher SGA costs, freight expenses, and unfavorable foreign currency.
The Building Climate Solutions segment reported $1.76 billion in net sales in 2024, a 17% increase compared to 2023, driven by higher sales volumes, favorable price and mix, and the contribution from the AES acquisition. Segment profit increased by $56.1 million or 16% compared to 2023, primarily due to the higher sales volumes, price and mix benefits, and the addition of AES, partially offset by higher factory inefficiencies and inflationary wage impacts.
Liquidity
As of December 31, 2024, Lennox maintained a strong liquidity position with $415.1 million in cash and cash equivalents. The Company's net debt to adjusted EBITDA ratio improved to 0.6x, down from 1.3x in the prior year quarter, reflecting its solid financial footing and ability to fund future growth initiatives.
Lennox's debt-to-equity ratio stood at 1.75 as of December 31, 2024. The Company had access to a $1.1 billion revolving credit facility, with $1.1 billion available after $2 million in outstanding letters of credit. Lennox's current ratio was 1.43, and its quick ratio was 0.90, indicating a healthy short-term liquidity position.
Geographic Performance
Lennox operates primarily in North America, with approximately 94% of 2024 revenue generated in the United States and Canada. The company does not have a significant international presence, which allows it to focus on its core markets and leverage its strong brand recognition and distribution networks in these regions.
Looking Ahead: Positioning for Continued Success
As Lennox transitions from the "recover and invest" phase to the "growth acceleration" phase of its self-help transformation plan, the Company is well-positioned to continue its strong momentum. The investments made over the past two years, such as the new commercial factory in Mexico and the Samsung joint venture, are expected to drive sustained revenue growth and further margin expansion in the coming years.
Lennox's guidance for 2025 reflects its confidence in the business, with the Company projecting core revenue growth of approximately 2% and adjusted earnings per share in the range of $22 to $23.50. The Company expects low single-digit volume growth in the Building Climate Solutions segment and a 4% revenue growth from the introduction of new low GWP products. Lennox anticipates an inflation impact of approximately 3% on costs and plans strategic investments of around $25 million for initiatives like information system advancements, distribution growth, and customer service improvements. The Company also expects to achieve cost productivity savings of $50 million.
Lennox's free cash flow guidance for 2025 is in the range of $650 million to $800 million, reflecting the Company's continued focus on operational efficiency and cash generation.
The Company's robust pipeline of strategic initiatives, including digital customer experience enhancements, expanded heat pump offerings, and a focus on improving parts and accessories attachment rates, are expected to fuel long-term value creation.
