Lennox International Inc. reported a total revenue of $5.195 billion for the fiscal year ending December 31, 2025, reflecting a decrease of 3% from $5.341 billion in 2024. The company's operating income remained stable at $1.042 billion, slightly up from $1.040 billion in the previous year. However, net income saw a minor decline to $806 million from $811 million in 2024, resulting in diluted earnings per share of $22.79, compared to $22.66 in the prior year. The decrease in revenue was attributed to a 13% drop in sales volumes, which was partially offset by a favorable price and mix effect of 9% and a 1% increase from the acquisition of Duro Dyne and Supco.
In terms of strategic developments, Lennox completed two significant acquisitions in 2023 and 2025. The acquisition of AES Industries in October 2023 aimed to enhance service and sustainability in the light commercial market, while the acquisition of Duro Dyne and Supco in October 2025, valued at $545 million, was intended to bolster the company's HVAC parts and supplies portfolio. These acquisitions are expected to contribute positively to the company's growth trajectory, with Duro Dyne and Supco already generating approximately $42 million in net sales since the acquisition.
Operationally, Lennox employed approximately 12,900 individuals as of December 31, 2025, with a significant portion based in the U.S. and Mexico. The company reported a 7% decrease in net sales for its Home Comfort Solutions segment, which totaled $3.343 billion, while the Building Climate Solutions segment experienced a 5% increase in net sales to $1.852 billion. The company also noted a shift in its inventory accounting method from LIFO to FIFO, which resulted in an increase in retained earnings by $106.6 million as of January 1, 2023.
Looking ahead, Lennox aims to sustain its market position through a balanced approach of organic growth and strategic investments. The company is focused on enhancing customer experience through digital innovations and improving fulfillment rates for HVAC equipment. Additionally, it plans to maintain resilient profit margins through pricing excellence and productivity enhancements. The company anticipates capital expenditures of approximately $250 million in 2026, primarily for general capital improvement projects, as it continues to adapt to market conditions and customer demands.
