LENNOX INTERNATIONAL INC

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. General:

References in this Quarterly Report on Form 10-Q to "we", "our", "us", "LII" or the "Company" refer to Lennox International Inc. and its subsidiaries, unless the context requires otherwise.

Basis of Presentation

The accompanying unaudited Consolidated Balance Sheet as of September 30, 2026, the accompanying unaudited Consolidated Statements of Operations, Comprehensive Income, and Stockholders' Equity for the three and nine months ended September 30, 2026 and 2025, and accompanying unaudited Consolidated Statements of Cash Flows for the nine months ended September 30, 2026 and 2025 should be read in conjunction with our audited consolidated financial statements and footnotes included in our Annual Report on Form 10-K for the year ended December 31, 2025.

The unaudited consolidated financial statements for all comparable prior periods presented have been retrospectively adjusted to reflect the prior-year change in method of accounting for certain inventories from last-in-first-out ("LIFO") to first-in, first-out ("FIFO").

The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. The accompanying consolidated financial statements contain all material adjustments, consisting principally of normal recurring adjustments, necessary for a fair presentation of our financial position, results of operations and cash flows. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to applicable rules and regulations, although we believe that the disclosures herein are adequate to make the information presented not misleading. The operating results for the interim periods are not necessarily indicative of the results that may be expected for a full year.

Our fiscal quarterly periods are comprised of approximately 13 weeks, but the number of days per quarter may vary year-over-year. Our quarterly reporting periods usually end on the Saturday closest to the last day of March, June, and September. Our fourth quarter and fiscal year ends on December 31, regardless of the day of the week on which December 31 falls. For convenience, the 13-week periods comprising each fiscal quarter are denoted by the last day of the respective calendar quarter.

Use of Estimates

The preparation of financial statements requires us to make estimates and assumptions about future events. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenues and expenses. Such estimates include the valuation of accounts receivable, inventories, goodwill, intangible assets and other long-lived assets, contingencies, guarantee obligations, indemnifications, and assumptions used in the calculation of income taxes, pension and post-retirement medical benefits, self-insurance and warranty reserves, and stock-based compensation, among others. These estimates and assumptions are based on our best estimates and judgment.

We evaluate these estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment. We believe these estimates and assumptions to be reasonable under the circumstances and will adjust such estimates and assumptions when facts and circumstances dictate. Volatile equity, foreign currency and commodity markets combine to increase the uncertainty inherent in such estimates and assumptions. Future events and their effects cannot be determined with precision and actual results could differ significantly from these estimates. Changes in these estimates will be reflected in the financial statements in future periods.

2. Reportable Business Segments:

We operate intwo reportable business segments of the heating, ventilation, air conditioning and refrigeration (“HVACR”) industry. Our segments are organized primarily by the nature of the products and services we provide. The following table describes each segment:

We use segment profit or loss as the primary measure of profitability to evaluate operating performance and to allocate capital resources. We define segment profit or loss as a segment’s income or loss from continuing operations before interest and income taxes included in the accompanying Consolidated Statements of Operations, excluding certain items. The reconciliation in the table below details the items excluded.

Any intercompany sales and associated profit (and any other intercompany items) are eliminated from segment results. There were no significant intercompany eliminations for the periods presented.

The chief operating decision maker uses segment profit or loss from operations, excluding certain items, to allocate resources (including employees, financial, or capital resources) for each segment predominantly in the annual budget and forecasting process. The chief operating decision maker considers budget-to-actual variances in segment profit or loss on a monthly basis when evaluating segment performance and making decisions about allocating resources to the segments.

Our chief operating decision maker is Alok Maskara, Chief Executive Officer.

Key financial information for each segment is shown below (in millions):

(1)On a consolidated basis, no revenue from transactions with a single customer was 10% or greater of our consolidated net sales for any of the periods presented.

(2)Other (income) expense is primarily comprised of income from equity method investments and (gains) losses and other expenses, net.

(3) We define segment profit as a segment's operating income included in the accompanying Consolidated Statements of Operations, excluding:

•Restructuring charges,

•Loss (gain) on sale from previous dispositions,

•Special litigation charges, and

•Acquisition costs.

The reconciliations of segment profit to Operating income and Net income before income taxes are presented below (in millions):

(1)We define segment profit as a segment's operating income (loss) included in the accompanying Consolidated Statements of Operations, excluding:

•Restructuring charges,

•Gain on sale from previous dispositions,

•Special litigation charges, and

•Acquisition costs.

(2)Recorded in Losses (gains) and other expenses, net in the accompanying Consolidated Statements of Operations.

(3)Corporate and other expenses include unallocated corporate costs related to corporate administrative functions such as tax, treasury, accounting, internal audit, legal and human resources.

Total assets by segment are shown below (in millions) as of:

The assets in the Corporate and Other primarily consist of cash, property, plant and equipment, short-term investments, and deferred tax assets. Assets recorded in the operating segments represent those assets directly associated with those segments.

Total capital expenditures by segment are shown below (in millions):

Depreciation and amortization expenses by segment are shown below (in millions):

The income from equity method investments is shown below (in millions):

Geographic Information

Property, plant and equipment, net for each major geographic area in which we operate, based on the domicile of our operations, are shown below (in millions) as of:

3. Earnings Per Share:

Basic earnings per share are computed by dividing net income by the weighted-average number of common shares outstanding during the period. Diluted earnings per share are computed by dividing net income by the sum of the weighted-average number of shares and the number of equivalent shares assumed outstanding, if dilutive, under our stock-based compensation plans.

The computations of basic and diluted earnings per share were as follows (in millions, except per share data):

(1)Amounts may not recalculate due to rounding.

For the three and nine months ended September 30, 2026 and 2025, there were no material stock appreciation rights or restricted stock units outstanding that were not included in the diluted earnings per share calculation as the assumed exercise of such rights would have been anti-dilutive.

4. Commitments and Contingencies:

Leases

We determine if an arrangement is a lease at inception. Operating leases are included in our Consolidated Balance Sheets as Right-of-use assets from operating leases, Current operating lease liabilities and Long-term operating lease liabilities. Finance leases are included in Property, plant and equipment, Current maturities of long-term debt and Long-term debt in our Consolidated Balance Sheets. We do not recognize a right-of-use asset and lease liability for leases with a term of 12 months or less. We do not separate non-lease components from lease components to which they relate and have accounted for the combined lease and non-lease components as a single lease component.

Many of our lease agreements contain renewal options; however, we do not recognize right-of-use assets or lease liabilities for renewal periods unless it is determined that we are reasonably certain of renewing the lease at inception or when a triggering event occurs. Some of our lease agreements contain rent escalation clauses (including index-based escalations), rent holidays, capital improvement funding or other lease concessions. We recognize our minimum rental expense on a straight-line basis based on the fixed components of a lease arrangement. We amortize this expense over the term of the lease beginning with the date of initial possession. Variable lease components represent amounts that are not fixed in nature and are not tied to an index or rate, and are recognized as incurred. Under certain of our third-party service agreements, we control a specific space or underlying asset used in providing the service by the third-party service provider. These arrangements meet the definition of a lease under Accounting Standards Codification ("ASC") 842 and therefore are accounted for under ASC 842.

In determining our right-of-use assets and lease liabilities, we apply a discount rate to the minimum lease payments within each lease agreement. ASC 842 requires us to use the rate of interest that a lessee would have to pay to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. When we cannot readily determine the discount rate implicit in the lease agreement, we utilize our incremental borrowing rate. To estimate our specific incremental borrowing rates over various periods (ranging from 1-year through 30-years), a comparable market yield curve consistent with our credit quality was calibrated to our publicly outstanding debt instruments.

We lease certain real and personal property under non-cancelable operating leases. Approximately 82% of our right-of-use assets and lease liabilities relate to our leases of real estate with the remaining amounts primarily relating to our leases of IT equipment, fleet vehicles and manufacturing and distribution equipment.

Product Warranties and Product Related Contingencies

We provide warranties to customers for some of our products and record liabilities for the estimated future warranty-related costs based on failure rates, cost experience, and other factors. We periodically review the assumptions used to determine the product warranty liabilities and will adjust the liabilities in future periods for changes in experience, as necessary.

Liabilities for estimated product warranty costs are included in the following captions on the accompanying Consolidated Balance Sheets (in millions) as of:

The changes in product warranty liabilities for the nine months ended September 30, 2026 were as follows (in millions):

Litigation

Antitrust Class Actions

On March 20, 2026, seven HVAC equipment manufacturers (and certain of their affiliated companies), including the Company, were named as defendants in a complaint filed in the U.S. District Court for the Eastern District of Michigan on behalf of a putative class that alleges violations of Section 1 of the Sherman Antitrust Act of 1890, as amended, and certain state laws. Additional class action complaints were filed in April 2026 in the same court, based on similar allegations. The cases were consolidated under the caption In re HVAC Equipment Antitrust Litigation, No. 2:26-cv-10949 (E.D. Mich.). On July 10, 2026, the plaintiffs filed three amended, consolidated class-action complaints.

The complaints allege that the defendants conspired to fix, raise, maintain, and/or stabilize prices of HVAC equipment. The alleged class is defined as including all persons who purchased HVAC equipment in the U.S. during the period from January 1, 2020 to the present which was manufactured by one or more defendants for end use in a residential or commercial building. The complaints seek to recover an unspecified amount of damages, injunctive relief, and attorneys’ fees on behalf of the putative class.

The Company disputes these allegations and plans to vigorously defend itself. At this stage of the antitrust litigation, the Company cannot reasonably estimate the range of possible loss, if any, or the timing, outcome, or consequence of this litigation. An adverse outcome in this litigation could have a material adverse impact on the Company’s business, financial position, results of operations, or cash flows.

Other Litigation

We are involved in a number of other claims and lawsuits incidental to the operation of our businesses. Insurance coverages are maintained and estimated costs are recorded for such claims and lawsuits, including costs to settle other claims and lawsuits, based on experience involving similar matters and specific facts known.

It is management's opinion that none of these claims or lawsuits or any threatened litigation will have a material adverse effect on our financial condition, results of operations or cash flows. Claims and lawsuits, however, involve uncertainties and it is possible that their eventual outcome could adversely affect our results of operations for a particular period.

5. Stock Repurchases:

Our Board of Directors has authorized a total of $5.0 billion to repurchase shares of our common stock (collectively referred to as the "Share Repurchase Plans"), including a $1.0 billion share repurchase authorization in May 2025. The Share Repurchase Plans allow us to repurchase shares from time to time in open market transactions and in privately negotiated transactions based on business, market, applicable legal requirements and other considerations. Such repurchases may also be made in compliance with Rule 10b5-1 trading plans entered into by us, which would permit common stock to be repurchased when we might otherwise be precluded from doing so under insider trading laws or self-imposed trading restrictions. The Share Repurchase Plans do not require the repurchase of a specific number of shares and may be terminated at any time. As of September 30, 2026, $707.7 million was available for repurchase under the Share Repurchase Plans.

For the three and nine months ended September 30, 2026, we repurchased 354,046 and 653,673 shares, at an aggregate cost, inclusive of fees, of $150.0 million and $301.9 million, respectively.

6. Revenue Recognition:

The following table disaggregates our revenue by business segment by geography which provides information as to the major source of revenue. See Note 2 for additional information on our reportable business segments and the products and services sold in each segment.

Home Comfort Solutions- We manufacture and market a broad range of furnaces, air conditioners, heat pumps, packaged heating and cooling systems, equipment and accessories to improve indoor air quality, comfort control products, replacement parts and supplies and related products for both the residential replacement and new construction markets in North America. These products are sold under various brand names and are sold either through direct sales to a network of independent installing dealers, including through our network of Lennox stores or to independent distributors. For the three months ended September 30, 2026 and 2025, direct sales represented 70% and 75% of revenues, respectively, and sales to independent distributors represented the remainder. For the nine months ended September 30, 2026 and 2025, direct sales represented 72% and 74% of revenues, respectively, and sales to independent distributors represented the remainder. Given the nature of our business, customer product orders are fulfilled at a point in time and not over a period of time.

Building Climate Solutions - In North America, we manufacture and sell unitary heating and cooling equipment used in light commercial applications, such as low-rise office buildings, restaurants, retail centers, churches and schools. These products are distributed primarily through commercial contractors and directly to national account customers in the planned replacement, emergency replacement and new construction markets. We manufacture and market equipment for the commercial refrigeration markets under the Heatcraft Worldwide Refrigeration name. Our products are used in the food retail, food service, cold storage as well as non-food refrigeration markets. We sell these products to distributors, installing contractors, engineering design firms, original equipment manufacturers and end-users. We also provide installation, service and preventive maintenance for HVAC national account customers in the United States and Canada; manufacture curb, curb adapters, drop box diffusers; offer HVAC recycling and salvage services; and focus on multi-family HVAC replacement for expired mechanical assets. Revenue related to service contracts is recognized as the services are performed under the contract based on the relative fair value of the services provided. For the three months ended September 30, 2026 and 2025, equipment sales repr esented 82% and 80% of revenues, respectively, and the remainder of our revenue was generated from our service business. For the nine months ended September 30, 2026 and 2025, equipment sales repr esented 83% and 80% of revenues, respectively, and the remainder of our revenue was generated from our service business.

Contract Liabilities - Our contract liabilities consist of advance payments and deferred revenue. Net contract liabilities consisted of the following (in millions) as of:

For the three months ended September 30, 2026 we recognized nominal revenues, for the three months ended September 30, 2025 we recognized $5.4 million, and for the nine months ended September 30, 2026 and 2025, we recognized revenue of $3.0 million and $8.5 million related to our contract liabilities at January 1, 2026 and 2025, respectively. Impairment losses recognized in our receivables and contract assets were de minimis in 2026 and 2025.

7. Other Financial Statement Details:

Inventories:

The components of inventories are as follows (in millions) as of:

(1) Raw materials and parts includes materials for production and repair parts.

Goodwill:

The changes in the carrying amount of goodwill in 2026, in total and by segment, are summarized in the table below (in millions):

(1) As discussed in Note 13, an update to our purchase price allocation of Duro Dyne and Supco resulted in a $4.9 million increase in goodwill.

(2) On July 13, 2026, we completed the acquisition of Dusk Acquisition II Corporation and its subsidiaries Heat Controller, LLC and Aitons Equipment ULC (collectively, "Heat Controller"). In connection with this acquisition, $88.2 million of goodwill was recorded and is included in the Home Comfort Solutions reporting segment. See Note 13 for additional information on the Heat Controller acquisition.

We monitor our reporting units for indicators of impairment throughout the year to determine if a change in facts or circumstances warrants a re-evaluation of our goodwill. We have not recorded any goodwill impairments for the nine months ended September 30, 2026 or in any periods presented.

Derivatives:

Objectives and Strategies for Using Derivative Instruments

Commodity Price Risk -We utilize a cash flow hedging program to mitigate our exposure to volatility in the prices of metal commodities used in our production processes. Our hedging program includes the use of futures contracts to lock in prices, and as a result, we are subject to derivative losses should the metal commodity prices decrease and gains should the prices increase. We utilize a dollar cost averaging strategy so that a higher percentage of commodity price exposures are hedged near-term and lower percentages are hedged at future dates. This strategy allows for protection against near-term price volatility while allowing us to adjust to market price movements over time.

Interest Rate Risk -A portion of our debt may bear interest at variable rates, and as a result, we are subject to variability in the cash paid for interest. To mitigate a portion of that risk, we may choose to engage in an interest rate swap hedging strategy to eliminate the variability of interest payment cash flows. We are not currently hedged against interest rate risk.

Foreign Currency Risk -Foreign currency exchange rate movements create a degree of risk by affecting the U.S. dollar value of assets and liabilities arising in foreign currencies. We seek to mitigate the impact of currency exchange rate movements on certain short-term transactions by periodically entering into foreign currency forward contracts.

Cash Flow Hedges

We have foreign exchange forward contracts and commodity futures contracts designated as cash flow hedges that are scheduled to mature through March 2028. Unrealized gains or losses from our cash flow hedges are included in Accumulated other comprehensive loss (“AOCL”) and are expected to be reclassified into earnings within the next 18 months based on the prices of the commodities and foreign currencies at the settlement dates. We recorded the following amounts in AOCL related to our cash flow hedges (in millions) as of:

(1) Assuming commodity prices and foreign currency exchange rates remain constant, we expect to reclassify $5.3 million of derivative gain as of September 30, 2026 into earnings within the next 12 months.

Stock-Based Compensation:

We issue various long-term incentive awards, including performance share units, restricted stock units and stock appreciation rights under the Lennox International Inc. 2019 Equity and Incentive Plan, as it may be amended and restated from time to time. Stock-based compensation expense related to continuing operations is included in Selling, general and administrative expenses in the accompanying Consolidated Statements of Operations as follows (in millions):

8. Pension Benefit Plans:

The components of net periodic benefit cost for pension benefits were as follows (in millions):

9. Income Taxes:

As of September 30, 2026, we had approximately $5.4 million in total gross unrecognized tax benefits. If recognized, $5.4 million would be recorded through the Consolidated Statements of Operations.

Our effective tax rate was 24.6% for the three months ended September 30, 2026 compared to 18.1% for the three months ended September 30, 2025. The increase in rate is primarily due to higher income in higher tax jurisdictions.

The Internal Revenue Service is currently auditing certain aspects of our U.S. federal income tax returns for 2021 and 2022, including cross border transactions. There are also ongoing U.S. state and local audits and other foreign audits covering fiscal years 2019 through 2024. We are generally no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations by taxing authorities for years prior to 2019. We believe that the positions taken on our tax returns are more likely than not to prevail on technical merits and that adequate amounts have been reserved for these audits. However, final resolution of ongoing audits could result in settlements or judgments in excess of our reserves, and such settlements or judgments could have a material adverse impact on our financial position, results of operations, and cash flows.

10. Lines of Credit and Financing Arrangements:

The following table summarizes our outstanding debt obligations and their classification in the accompanying Consolidated Balance Sheets (in millions) as of:

Commercial Paper Program

We utilize a commercial paper program (the “Program”) pursuant to which we may issue short-term, unsecured commercial paper notes (the “CP Notes”) under the exemption from registration contained in Section 4(a)(2) of the Securities Act of 1933, as amended. Amounts available under the Program may be borrowed, repaid, and re-borrowed from time to time, with the aggregate face or principal amount of the CP Notes outstanding under the Program at any time not to exceed $500.0 million. The CP Notes have maturities of up to 397 days from the date of issue and rank pari passu with all of our other unsecured and unsubordinated indebtedness. The net proceeds from issuances of the CP Notes are typically used for general corporate purposes. Our revolving credit facility serves as a liquidity backstop for the repayment of CP Notes outstanding under the Program. There were $455.1 million CP Notes outstanding under the Program as of September 30, 2026.

Our weighted average borrowing rate on the Program was as follows as of:

Long-Term Debt

Term Loan

On October 16, 2025, we entered into a Term Credit Agreement (the “Term Credit Agreement”) with Wells Fargo Bank, National Association, as administrative agent, and the other lenders party thereto. We borrowed $300.0 million pursuant to the Term Credit Agreement and used the net proceeds to repay existing borrowings under the Credit Agreement (as defined below). The Term Credit Agreement matures on October 16, 2027. Loans under the Term Credit Agreement bear interest at our election at a rate per annum equal to (i) a forward-looking term rate based on the secured overnight financing rate for the applicable interest period ("Term SOFR"), plus an applicable margin ranging between 0.90% and 1.025% per annum depending on our long-term unsecured debt rating, or (ii) the highest of the Wells Fargo Bank, National Association prime rate, the Federal Funds rate plus 0.50%, and Term SOFR for a one month tenor in effect on such day plus 1.00%, plus an applicable margin ranging between 0.00% and 0.025% per annum depending on our long-term unsecured debt rating. The Term Credit Agreement contains customary covenants and events of default that are substantially similar to the existing covenants and events of default in our Credit Agreement.

Our weighted average borrowing rate on the Term Credit Agreement was as follows as of:

Credit Agreement

On May 9, 2025, we entered into an Amendment and Restatement Agreement (the "Credit Agreement") to our existing unsecured revolving credit facility with JPMorgan Chase Bank, N.A., as administrative agent, and the other lenders party thereto. The Credit Agreement decreased our total revolving commitments from $1.1 billion to $1.0 billion with an option to increase the revolving commitments by up to $350 million at our request, subject to the terms and conditions of the Credit Agreement. The Credit Agreement also extended the maturity date of the revolving commitments from July 2026 to May 2030. We hadno outstanding borrowings and $1.7 million committed to standby letters of credit as of September 30, 2026. Subject to covenant limitations, $543.2 million was available for future borrowings after taking into consideration outstanding borrowings under our Program. Availability under the Credit Agreement is reduced by borrowings under the Program. The Credit Agreement includes a subfacility for swingline loans up to $65.0 million. Maturity of the Credit Agreement may be extended by the lenders pursuant totwo one-year extension options that we may request under the Credit Agreement.

Our weighted average borrowing rate on the Credit Agreement was as follows as of:

The Credit Agreement and the Term Credit Agreement (the "Credit Facilities") are guaranteed by certain of our subsidiaries (the "Guarantor Subsidiaries") and contain customary covenants applicable to us and our subsidiaries including limitations on indebtedness, liens, dividends, stock repurchases, mergers, and sales of all or substantially all of our assets. In addition, the Credit Facilities each contain a financial covenant requiring us to maintain, as of the last day of each fiscal quarter for the four prior fiscal quarters, a Total Net Leverage Ratio of no more than 3.50 to 1.00 (or, at our election, on up to two occasions following a material acquisition,4.00 to 1.00).

Our Credit Facilities contain customary events of default. These events of default include nonpayment of principal or other amounts, material inaccuracy of representations and warranties, breach of covenants, default on certain other indebtedness or receivables securitizations (cross default), certain voluntary and involuntary bankruptcy events, and the occurrence of a change in control. A cross default under our Credit Facilities could occur if:

•We fail to pay any principal or interest when due on any other indebtedness or receivables securitization exceeding $75.0 million; or

•We are in default in the performance of, or compliance with any term of any other indebtedness in an aggregate principal amount exceeding $75.0 million, or any other condition exists which would give the holders the right to declare such indebtedness due and payable prior to its stated maturity.

Each of our major debt agreements contains provisions by which a default under one agreement causes a default in the others (a cross default). If a cross default under our Credit Facilities or our senior unsecured notes were to occur, it could have a wider impact on our liquidity than might otherwise occur from a default of a single debt instrument or lease commitment.

If any event of default occurs and is continuing, the administrative agent, or lenders with a majority of the aggregate commitments may require the administrative agent to terminate our right to borrow under our Credit Agreement and accelerate amounts due under our Credit Facilities (except for a bankruptcy event of default, in which case such amounts will automatically become due and payable and the lenders’ commitments will automatically terminate).

We are currently in compliance with all covenant requirements.

Senior Unsecured Notes

In September 2023, we issued $500.0 million of senior unsecured notes, which will mature in September 2028 (the "2028 Notes") with interest being paid semi-annually in March and September at 5.50%. In July 2020, we issued $300.0 million of senior unsecured notes, which will mature on August 1, 2027 (the "2027 Notes," and collectively with the 2028 Notes, the "Notes") with interest being paid semi-annually in February and August at 1.70% per annum. On August 1, 2025, we repaid upon maturity $300.0 million of senior unsecured notes originally issued in 2020.

In the event of a credit rating downgrade below investment grade resulting from a change of control, holders of our senior unsecured notes will have the right to require us to repurchase all or a portion of the senior unsecured notes at a repurchase price equal to 101% of the principal amount of the notes, plus accrued and unpaid interest, if any. The Notes are guaranteed, on a senior unsecured basis, by the Guarantor Subsidiaries. The indenture governing the Notes contains covenants that, among other things, limit our ability and the ability of the Guarantor Subsidiaries to: create or incur certain liens; enter into certain sale and leaseback transactions; and enter into certain mergers, consolidations and transfers of substantially all of our assets. The indenture also contains a cross default provision which is triggered if we default on other debt of at least $75.0 million in principal which is then accelerated, and such acceleration is not rescinded within 30 days of the notice date. We are currently in compliance with all covenant requirements.

11. Comprehensive Income (Loss):

The following table provides information on items reclassified from AOCL to Net income in the accompanying Consolidated Statements of Operations (in millions):

The following table provides information on changes in AOCL, by component (net of tax), for the nine months ended September 30, 2026 (in millions):

12. Fair Value Measurements:

Fair Value Hierarchy

The methodologies used to determine the fair value of our financial assets and liabilities as of September 30, 2026 were the same as those used as of December 31, 2025.

Assets and Liabilities Carried at Fair Value on a Recurring Basis

Derivatives were classified as Level 2 and primarily valued using estimated future cash flows based on observed prices from exchange-traded derivatives. We also considered the counterparty's creditworthiness, or our own creditworthiness, as appropriate. Adjustments were recorded to reflect the risk of credit default, however, they were insignificant to the overall value of the derivatives. Refer to Note 7 for more information related to our derivative instruments.

Other Fair Value Disclosures

The carrying amounts of Cash and cash equivalents, Short-term investments, Accounts and notes receivable, net, Accounts payable, and other short-term debt facilities approximate fair value due to the short maturities of these instruments. The carrying amount of our Credit Facilities in Long-term debt and CP Notes also approximates fair value due to their variable-rate characteristics.

The fair value of our senior unsecured notes in Long-term debt, classified as Level 2, was based on the amount of future cash flows using current market rates for debt instruments of similar maturities and credit risk. The following table presents their fair value (in millions) as of:

13. Acquisitions:

Heat Controller

In July 2026, we acquired 100% of the outstanding shares of common stock of Dusk Acquisition II Corporation and its subsidiaries Heat Controller, LLC and Aitons Equipment ULC (collectively, "Heat Controller"). Heat Controller serves distributors across North America and strengthens the Company's ability to serve small and mid-size HVAC distributors by expanding access to differentiated equipment offerings while creating new opportunities to broaden our share in the North American HVAC market. Excluding cash received at the closing, the total cash consideration paid was $215.3 million.

The purchase price was allocated to the assets acquired and liabilities assumed based on management’s estimate of their respective fair values at the date of acquisition. Goodwill was calculated as the excess of the consideration transferred over the net assets recognized and represents the estimated future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. The factors contributing to the recognition of goodwill were the assembled workforce and strategic benefits that are expected to be realized from the acquisition.

The purchase price allocation is preliminary and subject to revision as additional information about the fair value of assets acquired and liabilities assumed becomes available. Under the terms of the purchase agreement, a final working capital adjustment is due in the fourth quarter of 2026. The preliminary allocation of the purchase price as of the acquisition date was as follows:

The purchase price allocation includes $74.6 million of acquired identifiable intangible assets, all of which have finite lives. The fair value of the identifiable intangible assets has been estimated using the income approach through a discounted cash flow analysis. The estimates are based on inputs that are not observable in the market, and therefore represent non-recurring Level 3 inputs.The determination of the useful lives is based upon various industry studies, historical acquisition experience, and economic factors.

Subsequent to the purchase of Heat Controller, we recognized net sales of approximately $29.5 million and the acquired business contributed approximately $1.2 million to the Home Comfort Solutions segment profit from the date of acquisition through September 30, 2026. Estimated tax deductible goodwill of $31.5 million was generated as a result of the acquisition.

Duro Dyne and Supco

In October 2025, we completed the acquisition of Duro Dyne and Supco, a robust portfolio of HVAC parts and supplies that complement our existing residential and commercial offerings. Under the terms of the purchase agreement, a final working capital adjustment was completed in the first quarter of 2026. This working capital adjustment resulted in a$2.3 million increase in the purchase price. Additionally, during the first quarter of 2026 we made certain purchase price adjustments. The following table details the purchase price adjustments that were made through the third quarter of 2026 (in millions):

(1)The intangible assets acquired were estimated using the income approach through a discounted cash flow analysis. The estimates are based on inputs that are not observable in the market, and therefore represent non-recurring Level 3 inputs.

The valuation of assets acquired and liabilities assumed in connection with the Duro Dyne and Supco acquisition was finalized in the third quarter of 2026.
