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, 2024, the accompanying unaudited Consolidated Statements of Operations for the three and six months ended June 30, 2024 and 2023, the accompanying unaudited Consolidated Statements of Comprehensive Income for the three and six months ended June 30, 2024 and 2023, the accompanying unaudited Consolidated Statements of Stockholders' Equity (Deficit) for the three and six months ended June 30, 2024 and 2023, and the accompanying unaudited Consolidated Statements of Cash Flows for the six months ended June 30, 2024 and 2023 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, 2023.

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:

Segment

Product or Services

Markets Served

Geographic Areas

Home Comfort Solutions

Furnaces, air conditioners, heat pumps, packaged heating and cooling systems, indoor air quality equipment, comfort control products, replacement parts and supplies

Residential Replacement;
Residential New Construction

United States
Canada

Building Climate Solutions

Unitary heating and air conditioning equipment, applied systems, controls, installation and service of commercial heating and cooling equipment, variable refrigerant flow commercial products, curb, curb adapters, drop box diffusers, HVAC recycling and salvage service, condensing units, unit coolers, fluid coolers, air cooled condensers, air handlers, process chillers, controls, compressorized racks

Light Commercial;
Food Preservation;
Non-Food Industry

United States
Canada

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 income taxes included in the accompanying Consolidated Statements of Operations, excluding certain items. The reconciliation in the table below details the items excluded.

Our corporate costs include those costs related to corporate functions such as legal, internal audit, treasury, human resources, tax compliance and senior executive staff. 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.

Segment Net Sales and Profit (Loss)

Net sales and segment profit (loss) for each segment, along with a reconciliation of segment profit (loss) to Operating income, are shown below (in millions):


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

Operating income	$	320.1	$	278.8	$	486.9	$	418.4

(1) The Corporate and Other segment included our European portfolio. In the fourth quarter of 2023 we completed the divestiture of our European operations.

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

◦The following items in Losses and other expenses, net:

▪Net change in unrealized losses (gains) on unsettled futures contracts,

▪Environmental liabilities and special litigation charges, and

▪Other items, net

◦Gain on sale from previous dispositions

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,
	2024		2023		2024		2023
Net income	$	245.9	$	217.2	$	370.2	$	315.2



Weighted-average shares outstanding – basic	35.6		35.5		35.6		35.5
Add: Potential effect of dilutive securities attributable to stock-based payments	0.2		0.1		0.2		0.1
Weighted-average shares outstanding – diluted	35.8		35.6		35.8		35.6




Earnings per share – Basic:	$	6.91	$	6.12	$	10.40	$	8.88




Earnings per share – Diluted:	$	6.87	$	6.10	$	10.34	$	8.85

The following stock appreciation rights and restricted stock units were outstanding but not included in the diluted earnings per share calculation as the assumed exercise of such rights would have been anti-dilutive (in millions, except for per share data):


	For the Three Months Ended June 30,		For the Six Months Ended June 30,
	2024	2023	2024	2023
Weighted-average number of shares	—	0.2	—	0.2

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 under 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 78% 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

We are involved in a number of 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 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 $4.0 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 July 2021. 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. 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, 2024, $546 million was available for repurchase under the Share Repurchase Plans.

6. Revenue Recognition:

The following table disaggregates our revenue by business segment by geography which provides information as to the major source of revenue.

We sell these products to distributors, installing contractors, engineering design firms, original equipment manufacturers and end-users. Lennox National Account Services provides installation, service and preventive maintenance for HVAC national account customers in the United States and Canada. AES manufactures curb, curb adapters, drop box diffusers, offers HVAC recycling and salvage services and focuses 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, 2024 and 2023, equipment sales represented 82% and 87% of revenues and the remainder of our revenue was generated from our service business. For the six months ended June 30, 2024 and 2023, equipment sales represented 81% and 86% of revenues and the remainder of our revenue was generated from our services business.

Corporate and Other - In Europe, we manufactured and marketed equipment for the global commercial refrigeration markets. We also manufactured and sold unitary heating and cooling products and applied systems. A de minimis amount of segment revenue related to services for start-up and commissioning activities. In the fourth quarter of 2023, we completed the divestiture of our European operations.

(1) As discussed in Note 13, an update to our purchase price allocation of AES in the first quarter of 2024 resulted in a $2.2 million reduction of goodwill.

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, 2024 or in any periods presented for our continuing businesses.

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 bears 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 November 2025. 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 17 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:


	June 30, 2024		December 31, 2023
Unrealized losses (gains), net on unsettled contracts	$	(5.6)	$	2.6
Income tax (benefit) expense	1.4		(0.6)
Unrealized losses (gains), net included in AOCL, net of tax (1)	$	(4.2)	$	2.0

(1) Assuming commodity prices and foreign currency exchange rates remain constant, we expect to reclassify $4.4 million of derivative gain as of June 30, 2024 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):


	For the Three Months Ended June 30,				For the Six Months Ended June 30,
	2024		2023		2024		2023
Stock-based compensation expense	$	6.7	$	7.7	$	13.3	$	13.8

8. Pension Benefit Plans:

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

Settlements and curtailments	0.3		0.1		0.3		0.3
Net periodic benefit cost	$	1.2	$	0.6	$	2.0	$	1.3

9. Income Taxes:

As of June 30, 2024, we had approximately $4.4 million in total gross unrecognized tax benefits. If recognized, $4.4 million would be recorded through the Consolidated Statements of Operations.

Our effective tax rate was 19.7% for the six months ended June 30, 2024 compared to 19.0% for the six months ended June 30, 2023. The increase in rate is primarily due to income allocated to high-tax jurisdictions offset by a favorable adjustment for excess tax benefits.

We are currently under a limited scope audit by the Internal Revenue Service for our 2021 and 2022 tax years. There are also ongoing U.S. state and local audits and other foreign audits covering fiscal years 2017 through 2023. 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 2017.

10. Lines of Credit and Financing Arrangements:

Total long-term debt	$	1,126.8	$	1,143.1
Total debt	$	1,287.8	$	1,305.2

Foreign Obligations

Through several of our foreign subsidiaries, we have facilities available to assist us in financing seasonal borrowing needs for our foreign locations. We had no outstanding foreign obligations as of June 30, 2024 or December 31, 2023 and there were no borrowings or repayments on these facilities during the six months ended June 30, 2024.

Commercial Paper Program

On October 25, 2023, we established a commercial paper program (the “Program”), as a replacement to our Asset Securitization Program which expired in November 2023, 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. CP Notes currently outstanding under the Program totaled $147.0 million as of June 30, 2024.

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


	June 30, 2024		December 31, 2023
Weighted average borrowing rate	5.56	%	5.66	%

Credit Agreement

We have an existing $1.1 billion unsecured revolving credit facility dated as of July 14, 2021 (as amended, the "Credit Agreement"), with JPMorgan Chase Bank, N.A., as administrative agent, and the other lenders party thereto. We had $0 outstanding borrowings and $1.7 million committed to standby letters of credit as of June 30, 2024. Subject to covenant limitations, $951.3 million was available for future borrowings after taking into consideration outstanding borrowings under our Program. The Credit Agreement includes a subfacility for swingline loans up to $65.0 million. The Credit Agreement will expire and outstanding loans will be required to be repaid in July 2026, unless maturity is 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 facility was as follows as of:


	June 30, 2024		December 31, 2023
Weighted average borrowing rate	—	%	6.67	%

The Credit Agreement is guaranteed by certain of our subsidiaries and contains 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 Agreement contains 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 Agreement contains 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 facility 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 Agreement 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 Agreement (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).

As of June 30, 2024, we believe we were 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%. We issued two series of senior unsecured notes on July 30, 2020 for $300.0 million each, which will mature on August 1, 2025 (the "2025 Notes") and August 1, 2027 (the "2027 Notes," and collectively with the 2025 Notes and the 2028 Notes, the "Notes") with interest being paid semi-annually in February and August at 1.35% and 1.70% respectively, per annum.

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 subsidiary guarantors 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. As of June 30, 2024, we believe we were 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, 2024 were the same as those used as of December 31, 2023.

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 Short-term debt approximate fair value due to the short maturities of these instruments. The carrying amount of our Credit Agreement 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:


	June 30, 2024		December 31, 2023
Senior unsecured notes	$	1,074.6	$	1,079.3

13. Prior Year Acquisition:

In October 2023, we completed the acquisition of AES, a company dedicated to service and sustainability in the light commercial market. Under the terms of the purchase agreement, a final working capital adjustment was completed in the first quarter of 2024. This working capital adjustment resulted in a $1.8 million reduction in the purchase price. Additionally, during the first quarter of 2024 we made certain purchase price adjustments. The following table details the purchase price adjustments that were made during the first quarter of 2024 (in millions):


	December 31, 2023		Adjustment		June 30, 2024
Net tangible assets acquired	$	17.6	$	(1.7)	$	15.9
Intangible assets acquired	36.9		2.1		39.0
Goodwill	40.4		(2.2)		38.2
Total investment	$	94.9	$	(1.8)	$	93.1

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, 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, 2023, 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. In addition to the two major business segments, Corporate and Other is also reported as a segment. 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 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.

Net Sales

Net sales for the second quarter of 2024 increased 3% as compared to the same period in 2023. This was primarily due to favorable price of 3%, higher sales volumes of 3%, and an increase in sales volumes of 2% from our AES acquisition, which were partially offset by a 5% reduction in sales due to the fourth quarter 2023 sale of our European businesses.

Gross Profit

Gross profit margins in the second quarter of 2024 increased 120 basis points ("bps") to 33.6% as compared to 32.4% in the same period in 2023. Gross margins increased 240 bps from favorable price and 10 bps from miscellaneous other items, which were partially offset by 70 bps from higher freight and distribution costs and 60 bps from higher material and product costs.

Selling, General and Administrative Expenses

Selling, general and administrative expenses ("SG&A") decreased $12 million to $169 million in the second quarter of 2024 as compared to $181 million in the same period in 2023 primarily due to a $16 million reduction in SG&A expenses from our fourth quarter of 2023 divestiture of our European businesses, which was partially offset by higher employee-related costs including increased incentive compensation. As a percentage of net sales, SG&A decreased 120 bps to 11.6%.

Income from Equity Method Investments

We participate in two joint ventures that are engaged in the manufacture and sale of compressors, unit coolers, and condensing units. We exert significant influence over these affiliates based upon our ownership, but do not control them due to venture partner participation. Accordingly, these joint ventures are accounted for under the equity method and their financial position and results of operations are not consolidated. We recognized income from equity method investments of $3 million in the second quarter of 2024 and in the second quarter of 2023.

Interest Expense, net

Interest expense, net decreased to $13 million in the second quarter of 2024 from $15 million in the same period in 2023 due to lower borrowings.

Income Taxes

Our effective tax rate was 19.9% for the second quarter of 2024 as compared to 17.6% in the same period in 2023. The increase in rate was primarily due to income allocated to high-tax jurisdictions partially offset by a favorable adjustment for excess tax benefits.

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, 2024 and 2023 (in millions):


	For the Six Months Ended June 30,

Net cash used in investing activities	(57.2)		(82.3)
Net cash used in financing activities	(118.3)		(33.8)

Net Cash Provided By Operating Activities - The change in net cash provided by operating activities for the six months ended June 30, 2024 compared to the net cash provided by operating activities for the same period in 2023 reflects changes in working capital and an increase in net income.

Capital expenditures in 2024 were related to our Commercial factory in Mexico, the general expansion of manufacturing capacity and equipment, and investments in systems and software to support the overall enterprise.

Net Cash Used In Financing Activities - Net cash used in financing activities for the six months ended June 30, 2024 increased to $118 million as compared to $34 million in the same period of 2023. The change was primarily due to changes in net borrowings and repayments of long-term debt.

Commercial Paper Program

On October 25, 2023, we established a commercial paper program, as a replacement to our Asset Securitization Program which expired in November 2023, pursuant to which we may issue short-term, unsecured commercial paper 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. CP Notes currently outstanding under the Program totaled $147.0 million as of June 30, 2024.

Credit Agreement

We have an existing $1.1 billion unsecured revolving credit facility dated as of July 14, 2021 (as amended, the "Credit Agreement"), with JPMorgan Chase Bank, N.A., as administrative agent, and the other lenders party thereto. We had 0 outstanding borrowings and $1.7 million committed to standby letters of credit as of June 30, 2024. Subject to covenant limitations, $951.3 million was available for future borrowings after taking into consideration outstanding borrowings under our Program. The Credit Agreement includes a subfacility for swingline loans up to $65.0 million. The Credit Agreement will expire and outstanding loans will be required to be repaid in July 2026, unless maturity is extended by the lenders pursuant to two one-year extension options that we may request under the Credit Agreement.

Senior Unsecured Notes

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 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. As of June 30, 2024, we believe we were 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 decreased to 69% as of June 30, 2024 from 82% as of December 31, 2023.

As of June 30, 2024, our senior credit ratings were Baa2 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 $47.6 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. Included in our cash and cash equivalents of $47.6 million as of June 30, 2024 was $20 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. An actual repatriation in the future from our non-U.S. subsidiaries could be subject to foreign withholding taxes and U.S. state taxes.

Guarantees Related to Our Debt Obligations

Our senior unsecured notes were issued by Lennox International Inc. ("Parent") and are unconditionally guaranteed by the Guarantor Subsidiaries. The Guarantor Subsidiaries are 100% owned and consolidated, all guarantees are full and unconditional, and all guarantees are joint and several.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
General	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, 2024, the accompanying unaudited Consolidated Statements of Operations for the three and six months ended June 30, 2024 and 2023, the accompanying unaudited Consolidated Statements of Comprehensive Income for the three and six months ended June 30, 2024 and 2023, the accompanying unaudited Consolidated Statements of Stockholders' Equity (Deficit) for the three and six months ended June 30, 2024 and 2023, and the accompanying unaudited Consolidated Statements of Cash Flows for the six months ended June 30, 2024 and 2023 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, 2023. 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.

Income Taxes	9. Income Taxes: As of June 30, 2024, we had approximately $4.4 million in total gross unrecognized tax benefits. If recognized, $4.4 million would be recorded through the Consolidated Statements of Operations. Our effective tax rate was 19.7% for the six months ended June 30, 2024 compared to 19.0% for the six months ended June 30, 2023. The increase in rate is primarily due to income allocated to high-tax jurisdictions offset by a favorable adjustment for excess tax benefits. We are currently under a limited scope audit by the Internal Revenue Service for our 2021 and 2022 tax years. There are also ongoing U.S. state and local audits and other foreign audits covering fiscal years 2017 through 2023. 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 2017.

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	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.
Recent Accounting Pronouncements
Leases	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 under 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 78% 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.
