Filing Explained

The July 13 acquisition completed a $205 million cash-and-capacity funding use, with Heat Controller entering Lennox’s results in the third quarter.

The Form 10-Q is an unaudited quarterly report covering interim financial statements, risks, and liquidity. Lennox International completed its acquisition of Heat Controller on July 13, 2026 for a purchase price of $205.0 million, funded with cash on hand and available borrowing capacity. Heat Controller’s results will enter Lennox’s financial statements beginning in the third quarter, while the purchase price remains subject to final working-capital adjustments.

Before that closing, the June 30, 2026 balance sheet reported $51.5 million of cash, $412.0 million of commercial paper, and $1,581.3 million of total debt. The company also reported $586.3 million of borrowing availability under its revolving credit agreement after considering commercial-paper borrowings. The disclosed funding structure therefore combines a completed acquisition use with existing debt obligations and borrowing capacity.

During the second quarter, Lennox repurchased 260,627 common shares, and $857.7 million remained available under its repurchase authorization. The completed purchases reduce shares outstanding, while the remaining authorization is capacity that the plans do not require the company to use.

The filing also updates the antitrust litigation: plaintiffs filed amended consolidated complaints on July 10, 2026; Lennox disputes the allegations and says it cannot estimate any potential loss or the litigation’s timing or outcome. The next concrete acquisition items are the final working-capital adjustment and the purchase-price allocation, which had not been finalized at the filing date.

LENNOX INTERNATIONAL INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
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 June 30, 2026, the accompanying unaudited Consolidated Statements of Operations, Comprehensive Income, and Stockholders' Equity, for the three and six months ended June 30, 2026 and 2025 and accompanying unaudited Consolidated Statements of Cash Flows for the six months ended June 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 in two 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:
 
SegmentProduct or ServicesMarkets ServedGeographic Areas
Home Comfort SolutionsFurnaces, air conditioners, heat pumps, packaged heating and cooling systems, indoor air quality equipment, comfort control products, replacement parts and supplies, water heatersResidential Replacement;

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.

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):

 For the Three Months Ended June 30,For the Six Months Ended June 30,

(1) Amounts may not recalculate due to rounding.

For the three and six months ended June 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
11


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 83% 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:

Litigation

Antitrust Class Action

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.
12



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 June 30, 2026, $857.7 million was available for repurchase under the Share Repurchase Plans.     

For the three and six months ended June 30, 2026, we repurchased 260,627 and 299,627 shares, at an aggregate cost, inclusive of fees, of $131.9 million and $151.9 million respectively.

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 June 30, 2026 and 2025, direct sales represented 73% and 74% of revenues, respectively, and sales to independent distributors represented the remainder. For the six months ended June 30, 2026 and 2025, direct sales represented 73% 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 June 30, 2026 and 2025, equipment sales represented 84% and 81% of revenues, respectively, and the remainder of our revenue was generated from our service business. For the six months ended June 30, 2026 and 2025, equipment sales represented 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:

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 six months ended June 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 December 2027. 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:
15

Unrealized gains, net on unsettled contracts$(14.0)$(23.3)
Income tax expense3.6 5.4 
Unrealized gains, net included in AOCL, net of tax (1)
$(10.4)$(17.9)
(1) Assuming commodity prices and foreign currency exchange rates remain constant, we expect to reclassify $10.2 million of derivative gain as of June 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):

Net periodic benefit cost$1.0 $1.0 $2.5 $2.1 
9. Income Taxes:

As of June 30, 2026, we had approximately $5.3 million in total gross unrecognized tax benefits. If recognized, $5.3 million would be recorded through the Consolidated Statements of Operations.

Our effective tax rate was 20.8% for the three months ended June 30, 2026 compared to 19.4% for the three months ended June 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.

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 $412.0 million CP Notes outstanding under the Program as of June 30, 2026.

Our weighted average borrowing rate on the Program was as follows as of:
June 30, 2026December 31, 2025
Weighted average borrowing rate4.11 %3.98 %

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.

June 30, 2026December 31, 2025
Weighted average borrowing rate4.55 %4.90 %

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 had no outstanding borrowings and $1.7 million committed to standby letters of credit as of June 30, 2026. Subject to covenant limitations, $586.3 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 to two 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:
June 30, 2026December 31, 2025
Weighted average borrowing rate % %

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
18


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.

12. Fair Value Measurements:

Fair Value Hierarchy

The methodologies used to determine the fair value of our financial assets and liabilities as of June 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.

19


Other Fair Value Disclosures

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

Senior unsecured notes$811.3 $817.4 

13. Prior Year Acquisitions:

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 during the first quarter of 2026 (in millions):
December 31, 2025AdjustmentJune 30, 2026
Net tangible assets acquired$39.1 $(4.2)$34.9 
Intangible assets acquired(1)
235.0  235.0 
Goodwill277.2 6.5 283.7 
Total investment$551.3 $2.3 $553.6 

(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 Company has substantially completed the purchase price allocation for the acquisition of Duro Dyne and Supco. While management believes the allocation is effectively complete as of June 30, 2026, the purchase price allocation remains subject to adjustment as additional information becomes available during the measurement period, which may extend up to one year from the acquisition date in accordance with ASC 805.

14. Subsequent Events:

Acquisition – Heat Controller

On July 13, 2026, the Company completed the previously announced acquisition 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 Lennox's share in the North American HVAC market. Excluding cash received at the closing, the purchase price for the acquisition was $205.0 million. We used cash on hand and available borrowing capacity to fund the purchase price. The purchase price is subject to final adjustments for net working capital. The financial results of Heat Controller will be included beginning in the third quarter of 2026.

Due to the timing of this transaction, the allocation of the purchase price has not yet been finalized.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934 (the "Exchange Act"), as amended, that are based on information currently available to management as well as management’s assumptions and beliefs as of the date such statements were made. All statements, other than statements of historical fact, included in this Quarterly Report on Form 10-Q constitute forward-looking statements, including but not limited to statements identified by forward-looking terminology, such as the words “may,” “will,” “should,” “plan,” “anticipate,” “believe,” “intend,” “estimate,” and “expect” and similar expressions. Such statements reflect our current views with respect to future events, based on what we believe are reasonable assumptions; however, such statements are subject to certain risks and uncertainties.

In addition to the specific uncertainties discussed elsewhere in this Quarterly Report on Form 10-Q, the risk factors set forth in Part I, “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2025, and those set forth in Part II, “Item 1A. Risk Factors” of this report, if any, may affect our performance and results of operations. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may differ materially from those in the forward-looking statements. We disclaim any intention or obligation to update or review any forward-looking statements or information, whether as a result of new information, future events or otherwise, except as required by law.

Business Overview

We operate in two reportable business segments of the HVACR industry, Home Comfort Solutions and Building Climate Solutions. For more detailed information regarding our reportable segments, see Note 2 in the Notes to the Consolidated Financial Statements.

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, throughout this Management’s Discussion and Analysis of Financial Condition and Results of Operations, the 13-week periods comprising each fiscal quarter are denoted by the last day of the respective calendar quarter.

We sell our products and services through a combination of direct sales, distributors and company-owned stores. The demand for our products and services is seasonal and can be significantly impacted by the weather. Warmer than normal summer temperatures generate demand for replacement air conditioning and refrigeration products and services, and colder than normal winter temperatures have a similar effect on heating products and services. Conversely, cooler than normal summers and warmer than normal winters depress the demand for HVACR products and services. In addition to weather, demand for our products and services is influenced by national and regional economic and demographic factors, such as interest rates, the availability of financing, regional population and employment trends, new construction, general economic conditions, and consumer spending habits and confidence. A substantial portion of the sales in each of our business segments is attributable to replacement business, with the balance comprised of new construction business.

The principal elements of cost of goods sold are components, raw materials, factory overhead, labor, estimated costs of warranty expense, and freight and distribution costs. The principal raw materials used in our manufacturing processes are steel, aluminum and copper. In recent years, pricing volatility for these commodities and related components has impacted us and the HVACR industry in general. We seek to mitigate the impact of certain commodity price volatility and tariffs through a combination of pricing actions, vendor contracts, improved production efficiency, and cost reduction initiatives. We also partially mitigate volatility in the prices of these commodities by entering into futures contracts and fixed forward contracts.

Financial Overview

Results for the second quarter of 2026 were mixed as our Home Comfort Solutions segment faced volume headwinds driven by market softness. Overall our net sales increased 3% and our segment profit was relatively flat as compared to prior year. For our Home Comfort Solutions segment, net sales decreased 7% and segment profit decreased $30 million. For our Building Climate Solutions segment, net sales increased 24% and segment profit increased $35 million.

Financial Highlights

Net sales of $1,545 million in the second quarter of 2026 reflected a 3% increase as compared to the same period in 2025.
Operating income in the second quarter of 2026 increased $6 million to $355 million as favorable mix and price were partially offset by lower sales volumes, higher product costs and higher freight and distribution costs.
Net income for the second quarter of 2026 was $269 million.
Diluted earnings per share was $7.72 per share in the second quarter of 2026 as compared to $7.71 per share in the same period in 2025.
For the six months ended June 30, 2026, we returned $91 million to shareholders through dividend payments and repurchased $151 million of common stock through our share repurchase program.

Recent Developments

Throughout 2025 and 2026, the U.S. government implemented new tariff measures under various authorities, including the International Emergency Economic Powers Act ("IEEPA") and Sections 122, 232, and 301 of the Trade Expansion Act of 1962.

In February 2026, the U.S. Supreme Court ruled against tariffs imposed under IEEPA, and U.S. Customs and Border Protection is now processing valid court-ordered IEEPA refunds. The ruling did not repeal Section 232 tariffs on steel, copper, and aluminum or Section 301 tariffs on covered Chinese HVAC imports.

Following this ruling, the U.S. presidential administration imposed a temporary surcharge, known as Section 122, which applied a 10% global tariff on most imported products, effective through July 24, 2026. The temporary surcharge was replaced by a new Section 301 forced labor tariffs framework of 10% or 12.5%, covering imports from 60 trading partners. Section 232 articles and qualifying USMCA goods are excluded from this new framework. Section 232 tariffs also continued to evolve, with modifications implemented in April and June 2026. The Company is evaluating the potential impact of all tariff actions on future material costs and sourcing decisions.

Interest Expense, net

Interest expense, net increased to $15 million in the second quarter of 2026 from $8 million in the same period in 2025 primarily due to increased borrowings on our commercial paper facility and our term loan agreement entered into in October of 2025.

Income Taxes

Our effective tax rate was 20.8% for the second quarter of 2026 as compared to 19.4% in the same period in 2025. The increase in the rate is primarily due to higher income in higher tax jurisdictions.

Liquidity and Capital Resources

Our working capital and capital expenditure requirements are generally met through internally generated funds, bank lines of credit and a commercial paper program (as described below). Working capital needs are generally greater in the first and second quarters due to the seasonal nature of our business cycle.

Statement of Cash Flows

The following table summarizes our cash flow activity for the six months ended June 30, 2026 and 2025 (in millions):
For the Six Months Ended June 30,
20262025
Net cash provided by operating activities$188.1 $51.0 
Net cash used in investing activities(90.1)(51.6)
Net cash used in financing activities(76.1)(368.2)

Net Cash Provided By Operating Activities - The change in net cash provided by operating activities for the six months ended June 30, 2026 compared to the net cash provided by operating activities for the same period in 2025 is primarily due to favorable working capital changes.

Net Cash Used In Investing Activities - Capital expenditures were $91 million for the six months ended June 30, 2026 compared to $54 million in the same period of 2025. The increase in capital expenditures was primarily driven by strategic investments in land and buildings that will support future product innovation centers.

Net Cash Used In Financing Activities - Net cash used in financing activities for the six months ended June 30, 2026 decreased to $76 million as compared to $368 million used during the same period of 2025. The change was primarily due to changes in net borrowings and repayments of long-term debt and repurchases of common stock through our share repurchase
26


program. We repurchased $151 million of shares for the six months ended June 30, 2026 and returned $91 million to shareholders through dividend payments.

     Total long-term debt$1,149.2 
Total debt$1,581.3 

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 are $412.0 million CP Notes outstanding under the Program as of June 30, 2026.

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 had no outstanding borrowings and $1.7 million committed to standby letters of credit as of June 30, 2026. Subject to covenant limitations, $586.3 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 to two one-year extension options that we may request under the Credit Agreement.

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. 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
27


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.

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. All the Notes are guaranteed, on a senior unsecured basis, by certain of our subsidiaries that guarantee indebtedness under our Credit Agreement (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.

Financial Leverage

We periodically review our capital structure to ensure the appropriate levels of leverage and liquidity. We may access the capital markets, as necessary, based on business needs and to take advantage of favorable interest rate environments or other market conditions. We also evaluate our debt-to-capital and debt-to-EBITDA ratios to determine, among other considerations, the appropriate targets for capital expenditures and share repurchases under our share repurchase programs. Our debt-to-total-capital ratio increased to 55% at June 30, 2026, as compared to 54% at December 31, 2025.

As of June 30, 2026, our senior credit ratings were Baa1 with a stable outlook, and BBB with a stable outlook, by Moody's Investors Service, Inc. ("Moody's") and Standard & Poor's Rating Group ("S&P"), respectively. The security ratings are not a recommendation to buy, sell or hold securities and may be subject to revision or withdrawal at any time by the assigning rating agency. Each rating should be evaluated independently of any other rating. Our goal is to maintain investment grade ratings from Moody's and S&P to help ensure the capital markets remain available to us.    

Liquidity

We believe our cash and cash equivalents of $51.5 million, future cash generated from operations and available borrowing capacity are sufficient to fund operations, planned capital expenditures, future contractual obligations, potential share repurchases and dividends, and other needs in the foreseeable future. In July 2026, we acquired Heat Controller for approximately $205 million. For more information, see Note 14 in the Notes to the Consolidated Financial Statements. Included in our cash and cash equivalents of $51.5 million as of June 30, 2026 was $21.8 million of cash held in foreign locations. Our cash held in foreign locations is used for investing and operating activities in those locations, and we generally do not have the need or intent to repatriate those funds to the United States.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

As required by Rule 13a-15 under the Exchange Act, we carried out an evaluation, under the supervision and with the participation of our current management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that, as of June 30, 2026, our disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed by us in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the applicable rules and forms, and that such information is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Part II - Other Information

Item 1. Legal Proceedings

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 Claims

We are involved in a number of other claims and lawsuits incidental to the operation of our businesses. Where appropriate, insurance coverages are maintained and estimated costs are recorded for such claims and lawsuits. It is management's opinion that none of these other claims or lawsuits will have a material adverse effect, individually or in the aggregate, on our financial position, results of operations or cash flows.

Item 1A. Risk Factors
In addition to the other information set forth in this Quarterly Report on Form 10-Q, you should carefully consider the risk factors discussed in Part I, “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2025, which could materially affect our business, financial condition or results of operations. There have been no material changes to our risk factors from those disclosed in our Annual Report on Form 10-K for the year ended December 31, 2025.
