Material Changes vs. Prior Period
- Revenue Decline: Net sales decreased 3% to $5.195 billion, driven by a 13% decrease in sales volumes, partially offset by favorable price and mix (9%) and the Duro Dyne/Supco acquisition (1%).
- Segment Performance:
- Home Comfort Solutions: Sales down 7% and profit down $32 million due to lower volumes.
- Building Climate Solutions: Sales up 5% and profit up $33 million, driven by favorable price/mix and the Duro Dyne acquisition.
- Accounting Change: The company changed its inventory accounting method from LIFO to FIFO in Q4 2025. This change increased Retained Earnings by $106.6 million (as of Jan 1, 2023) and increased 2025 net income by $15.7 million compared to what would have been reported under LIFO.
- Cash Flow: Operating cash flow decreased $188 million to $758 million, primarily due to a $217 million increase in net working capital.
- Acquisitions: Completed the acquisition of Duro Dyne and Supco for $545 million in cash consideration, adding $277.2 million in goodwill.
Guidance, Outlook, and Risks
- Capital Allocation: The company returned $655 million to shareholders in 2025 ($173 million in dividends and $482 million in share repurchases). As of Dec 31, 2025, $1,009.6 million remains available under the share repurchase plan.
- Capital Expenditures: Expected to be approximately $250 million in 2026 for general capital improvement projects.
- Debt Structure: Entered a new $300 million Term Loan in October 2025 and amended its revolving credit facility to $1.0 billion. Total debt-to-capital ratio decreased to 54%.
- Key Risks:
- Commodity Prices: Exposure to volatility in steel, copper, and aluminum prices.
- Weather: Sales are seasonal and sensitive to weather patterns (cooler summers/warmer winters depress demand).
- Regulatory: Ongoing changes in energy efficiency standards and refrigerant regulations (HFC phase-down).
- Supply Chain: Reliance on single-location production facilities and key suppliers.
Investor Verification Checklist
- Inventory Accounting Impact: Verify the long-term implications of the LIFO-to-FIFO switch on future cost of goods sold and tax liabilities.
- Acquisition Integration: Monitor the integration progress and synergy realization of the Duro Dyne and Supco acquisitions.
- Working Capital Trends: Assess the sustainability of the $217 million increase in working capital and its impact on future operating cash flow.
- Debt Covenants: Confirm continued compliance with the Total Net Leverage Ratio covenant (max 3.50:1.00) given the increased debt load from the term loan and commercial paper.
- Warranty Liabilities: Review the $167.2 million product warranty liability and assumptions regarding failure rates and costs.
