WATSCO, INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED UNAUDITED FINANCIAL STATEMENTS

September 30, 2024

(In thousands, except share and per share data)

1.	BASIS OF PRESENTATION

Basis of Consolidation

Watsco, Inc. (collectively with its subsidiaries, “Watsco,” the “Company,” “we,” “us,” or “our”) was incorporated in Florida in 1956 and is the largest distributor of air conditioning, heating and refrigeration equipment and related parts and supplies (“HVAC/R”) in the HVAC/R distribution industry in North America. The accompanying September 30, 2024 interim condensed consolidated unaudited financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and note disclosures normally included in the annual financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to those rules and regulations, but we believe the disclosures made are adequate to make the information presented not misleading. In the opinion of management, all adjustments, consisting of normal and recurring adjustments, necessary for a fair presentation have been included in the condensed consolidated unaudited financial statements included herein. These statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our 2023 Annual Report on Form

10-K.

The condensed consolidated unaudited financial statements include the accounts of Watsco, all of its wholly owned subsidiaries, the accounts of four joint ventures with Carrier Global Corporation, which we refer to as Carrier, in which we have a controlling interest, the accounts of Carrier InterAmerica Corporation and Carrier (Puerto Rico), Inc., in each of which we have an 80% controlling interest, and Carrier has a 20%

non-controlling

interest, and our 38.4% investment in Russell Sigler, Inc., which is accounted for under the equity method of accounting. All significant intercompany balances and transactions have been eliminated in consolidation.

The results of operations for the quarter and nine months ended September 30, 2024 are not necessarily indicative of the results to be expected for the year ending December 31, 2024. Sales of residential central air conditioners, heating equipment, and parts and supplies are seasonal. Furthermore, profitability can be impacted favorably or unfavorably based on weather patterns, particularly during the Summer and Winter selling seasons. Demand related to the residential central air conditioning replacement market is typically highest in the second and third quarters, and demand for heating equipment is usually highest in the first and fourth quarters. Demand related to the new construction sectors throughout most of the markets we serve tends to be fairly evenly distributed throughout the year and depends largely on housing completions and related weather and economic conditions.

Short-Term Cash Investments

Short-term cash investments consist of certificates of deposit that have varying maturities through March 2025.

Equity Method Investments

Investments in which we have the ability to exercise significant influence, but do not control, are accounted for under the equity method of accounting and are included in investment in unconsolidated entity in our condensed consolidated unaudited balance sheets. Under this method of accounting, our proportionate share of the net income or loss of the investee is included in other income in our condensed consolidated unaudited statements of income. The excess, if any, of the carrying amount of our investment over our ownership percentage in the underlying net assets of the investee is attributed to certain fair value adjustments with the remaining portion recognized as goodwill.

Use of Estimates

The preparation of condensed consolidated unaudited financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated unaudited financial statements and the reported amounts of revenues and expenses for the reporting period. Significant estimates include valuation reserves for accounts receivable, net realizable value adjustments to inventories, income taxes, reserves related to loss contingencies and the valuation of goodwill, indefinite-lived intangible assets, and long-lived assets. While we believe that these estimates are reasonable, actual results could differ from such estimates.

Recently Adopted Accounting Standards

Segment Reporting

In September 2023, the Financial Accounting Standards Board (“FASB”) issued guidance that enhances segment reporting primarily by expanding the disclosures about significant segment expenses. Under the new standard, an entity will be required to disclose significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”), how the CODM assesses

segment performance and decides how to allocate resources, the title and position of the CODM, and certain other disclosures. This guidance is effective prospectively and is effective for annual periods beginning after December 15, 2023 and for interim periods beginning after December 15, 2024. The adoption of this guidance on January 1, 2024 did not have a material impact on our consolidated financial statements.

Recently Issued Accounting Standards Not Yet Adopted

Income Taxes

In December 2023, the FASB issued guidance that enhances annual income tax disclosures primarily by disaggregating the existing disclosures related to the effective tax rate reconciliation and income taxes paid. Under the new guidance, an entity will be required to disclose specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. An entity will also be required to disclose the amount of income taxes paid disaggregated by federal, state, and foreign, and by individual jurisdictions equal to or greater than

five percent

of total income taxes paid. This guidance is effective prospectively and is effective for annual periods beginning after December 15, 2024. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements.

Climate Disclosures

In March 2024, the Securities and Exchange Commission (“SEC”) adopted rules to enhance and standardize disclosures related to the impacts and risks of climate-related matters. Under the new rules, an entity will be required to disclose information about climate-related risks that have materially impacted, or are likely to have a material impact, on its business strategy, results of operations, or financial condition. In addition, certain disclosures related to severe weather events, other natural conditions, and greenhouse gas emissions will be required in the audited financial statements. These rules are effective prospectively and are effective for annual periods beginning with the year ending December 31, 2025. On April 4, 2024, the SEC announced that it will stay

implementation of its final rules pending the results of a legal challenge. We will continue to assess the impact of these rules on our consolidated financial statements while the stay is in place.

Commercial Specialists, Inc.

On February 1, 2024, one of our wholly owned subsidiaries acquired Commercial Specialists, Inc. (“CSI”), a distributor of HVAC products with annual sales of approximately $13,000, operating from two locations in Kentucky and Ohio. Consideration for the purchase consisted of $6,037 in cash, 1,904 shares of Common stock having a fair value of $752, and $562 for repayment of indebtedness, net of cash acquired of $1,426. The preliminary purchase price resulted in the recognition of $2,469 in goodwill. The tax basis of such goodwill is deductible for income tax purposes over 15 years.

Gateway Supply Company, Inc.

On September 1, 2023, we acquired substantially all the assets and assumed certain of the liabilities of Gateway Supply Company, Inc. (“GWS”), a plumbing and HVAC distributor with annual sales of approximately $180,000, operating from 15 locations in South Carolina and one location in Charlotte, North Carolina. We formed a new, wholly owned subsidiary, Gateway Supply LLC, that operates this business. Consideration for the net purchase price consisted of $4,000 in cash, net of cash acquired of $3,102, and 280,215 shares of Common stock having a fair value of $101,645, net of a discount for lack of marketability. Of the 280,215 shares of Common stock issued, 21,228 shares

ere subject to a contractual restriction that generally prohibit

d the sale or other transfer of such shares by GWS and its permitted transferees for a period of one year following the closing date with respect to half of such shares, and two years following the closing date with respect to the other half of such shares. The purchase price resulted in the recognition of $69,086 in goodwill and intangibles. The fair value of the identified intangible assets was $44,000 and consisted of $18,600 in trade names and distribution rights, and $25,400 in customer relationships to be amortized over an

Capitol District Supply Co., Inc.

On March 3, 2023, one of our wholly owned subsidiaries acquired Capitol District Supply Co., Inc., a distributor of plumbing and air conditioning and heating products with annual sales of approximately $13,000, operating from three locations in New York. Consideration for the purchase consisted of $1,217 in cash, net of cash acquired of $144, and $1,851 for repayment of indebtedness. The purchase price resulted in the recognition of $1,055 in goodwill and intangibles. The fair value of the identified intangible assets was $606 and consisted of $430 in trade names and distribution rights, and $176 in customer relationships to be amortized over an

18-year

period. The tax basis of such goodwill is deductible for income tax purposes over 15 years.

The results of operations of these acquisitions have been included in the condensed consolidated unaudited financial statements from their respective dates of acquisition. The pro forma effect of these acquisitions was not deemed significant to our condensed consolidated unaudited financial statements.

6.	DERIVATIVES

We enter into foreign currency forward and option contracts to offset the earnings impact that foreign exchange rate fluctuations would otherwise have on certain monetary liabilities that are denominated in nonfunctional currencies.

Derivatives Not Designated as Hedging Instruments

We have entered into foreign currency forward and option contracts that are either not designated as hedges or did not qualify for hedge accounting. These derivative instruments were effective economic hedges for all of the periods presented. The fair value gains and losses on these contracts are recognized in earnings as a component of selling, general and administrative expenses. We had only one foreign currency exchange contract not designated as a hedging instrument at September 30, 2024, the total notional value of which was $8,900. Such contract expired in October 2024.

We recognized gains (losses) of $

1,312

and $

(371

) from foreign currency forward and option contracts not designated as hedging instruments in our condensed consolidated unaudited statements of income for the quarters ended September 30, 2024 and 2023, respectively. We recognized gains (losses) of $

2,908

and $

(2,423

) from foreign currency forward and option contracts not designated as hedging instruments in our condensed consolidated unaudited statements of income for the nine months ended September 30, 2024 and 2023, respectively.

7.	FAIR VALUE MEASUREMENTS

The following tables present our assets and liabilities carried at fair value that are measured on a recurring basis:

The following is a description of the valuation techniques used for these assets and liabilities, as well as the level of input used to measure fair value:

Short-term cash investments

– these investments consist of certificates of deposit that have varying maturities through March 2025. We classify these investments within Level 2 of the valuation hierarchy because fair value is based on indirectly observable market inputs.

13 of 28

Table of Contents

Derivative financial instruments

– these derivatives are foreign currency forward and option contracts. See Note 6. Fair value is based on observable market inputs, such as forward rates in active markets; therefore, we classify these derivatives within Level 2 of the valuation hierarchy.

Equity securities

– these investments are exchange-traded equity securities. Fair values for these investments are based on closing stock prices from active markets and are therefore classified within Level 1 of the fair value hierarchy.

Private equities

– other investments in which fair value inputs are unobservable and are therefore classified within Level 3 of the fair value hierarchy.

8 .	SHAREHOLDERS’ EQUITY

Dividend Reinvestment Plan

On March 29, 2024, we implemented the Watsco, Inc. Dividend Reinvestment Plan (the “Plan”), under which existing shareholders may, in accordance with the Plan, acquire shares of the Company’s Common stock or Class B common stock, as applicable (collectively “common stock”), by reinvesting all or a portion of the cash dividends paid on such shareholders’ shares of common stock. The Plan has been registered under the Securities Act of 1933, as amended (the “Securities Act”), pursuant to our automatically effective shelf registration statement on Form

S-3

(File

No. 333-260758).

During the quarter and nine months ended September 30, 2024, we issued 13,394 and 13,398 shares of common stock under the Plan, respectively.

At-the-Market

Offering Program

On August 6, 2021, we executed a sales agreement with Robert W. Baird & Co. Inc. (“Baird”), which enabled the Company to issue and sell shares of Common stock in one or more negotiated transactions or transactions that are deemed to be “at the market” offerings as defined in Rule 415 under the Securities Act of 1933, as amended (the “Securities Act”), for a maximum aggregate offering amount of up to $300,000 (the “2021 ATM Program”).

During the quarter ended March 31, 2024, we issued and sold 712,000 shares of Common stock under the 2021 ATM Program for net proceeds of $281,784. Direct costs of $33 incurred in connection with the offering were charged against the proceeds from the sale of Common stock and reflected as a reduction of

paid-in

capital. Cumulatively, $298,455 of Common stock was sold under the 2021 ATM Program.

On May 3, 2024, we executed an amended and restated sales agreement with Baird (the “2024 ATM Program”), which enables the further issuance of up to $400,000 of Common stock. At September 30, 2024, $400,000 was available for sale under the 2024 ATM Program. The offer and sale of shares under the 2024 ATM Program were registered under the Securities Act pursuant to our automatically effective shelf registration statement on Form

S-3

(File

No. 333-260758).

Common Stock Dividends

We paid cash dividends of $2.70, $2.45, $7.85, and $7.35 per share on both Common and Class B common stock during the quarters and nine months ended September 30, 2024 and 2023, respectively.

During the nine months ended September 30, 2024 and 2023, we received proceeds of $1,734 and $1,696, respectively, for shares of our Common stock purchased under our employee stock purchase plan.

9 .	COMMITMENTS AND CONTINGENCIES

Litigation, Claims, and Assessments

We are involved in litigation incidental to the operation of our business. We vigorously defend all matters in which we or our subsidiaries are named defendants and, for insurable losses, maintain significant levels of insurance to protect against adverse judgments, claims or assessments that may affect us. Although the adequacy of existing insurance coverage and the outcome of any legal proceedings cannot be predicted with certainty, based on the current information available, we do not believe the ultimate liability associated with any known claims or litigation will have a material adverse effect on our financial condition or results of operations.

Self-Insurance

Self-insurance reserves are maintained relative to company-wide casualty insurance and health benefit programs. The level of exposure from catastrophic events is limited by the purchase of stop-loss and aggregate liability reinsurance coverage. When estimating the self-insurance liabilities and related reserves, management considers several factors, which include historical claims experience, demographic factors, severity factors, and valuations provided by independent third-party actuaries. Management reviews its assumptions with its independent third-party actuaries to evaluate whether the self-insurance reserves are adequate. If actual claims or adverse development of loss reserves occur and exceed these estimates, additional reserves may be required. Reserves in the amounts of $8,351 and $9,747 at September 30, 2024 and December 31, 2023, respectively, were established related to such programs and are included in accrued expenses and other current liabilities in our condensed consolidated unaudited balance sheets.

Purchase Obligations

At September 30, 2024, we were obligated under various

non-cancelable

purchase orders with our key suppliers for goods aggregating approximately

$460,000, with approximately $250,000 attributable to Carrier and its affiliates.

10.	RELATED PARTY TRANSACTIONS

Purchases from Carrier and its affiliates comprised 61% and 67% of all inventory purchases made during the quarters ended September 30, 2024 and 2023, respectively. Purchases from Carrier and its affiliates comprised 62% and 65% of all inventory purchases made during the nine months ended September 30, 2024 and 2023, respectively. At September 30, 2024 and December 31, 2023, approximately $128,000 and $100,000, respectively, was payable to Carrier and its affiliates, net of receivables. We also sell HVAC products to Carrier and its affiliates. Revenues in our condensed consolidated unaudited statements of income for the quarters and nine months ended September 30, 2024 and 2023 included approximately $24,000, $34,000, $64,000, and $88,000, respectively, of sales to Carrier and its affiliates. We believe these transactions are conducted on terms equivalent to an

arm’s-length

basis in the ordinary course of

business.

Company Overview

Watsco, Inc. was incorporated in Florida in 1956, and, together with its subsidiaries (collectively, “Watsco,” the “Company,” or “we,” “us,” or “our”) is the largest distributor of air conditioning, heating, and refrigeration equipment, and related parts and supplies (“HVAC/R”) in the HVAC/R distribution industry in North America. At September 30, 2024, we operated from 689 locations in 43 U.S. States, Canada, Mexico, and Puerto Rico with additional market coverage on an export basis to portions of Latin America and the Caribbean.

Revenues primarily consist of sales of air conditioning, heating, and refrigeration equipment, and related parts and supplies. Selling, general and administrative expenses primarily consist of selling expenses, the largest components of which are salaries, commissions, and marketing expenses that are variable and correlate to changes in sales. Other significant selling, general and administrative expenses relate to the operation of warehouse facilities, including a fleet of trucks and forklifts, and facility rent, a majority of which we operate under non-cancelable operating leases.

16 of 28

Sales of residential central air conditioners, heating equipment, and parts and supplies are seasonal. Furthermore, profitability can be impacted favorably or unfavorably based on weather patterns, particularly during the Summer and Winter selling seasons. Demand related to the residential central air conditioning replacement market is typically highest in the second and third quarters, and demand for heating equipment is usually highest in the first and fourth quarters. Demand related to the new construction sectors throughout most of the markets we serve tends to be fairly evenly distributed throughout the year and depends largely on housing completions and related weather and economic conditions.

Climate Change and Reductions in CO₂e Emissions

We believe that our business plays an important and significant role in the drive to lower CO₂e emissions. According to the United States Department of Energy, heating and air conditioning accounts for roughly half of household energy consumption in the United States. As such, replacing older, less efficient HVAC systems with higher efficiency systems is one of the most meaningful steps homeowners can take to reduce their electricity costs and carbon footprints.

The overwhelming majority of new HVAC systems that we sell replace systems that likely operate below current minimum efficiency standards in the United States and may use more harmful refrigerants that have been, or are being, phased-out. As consumers replace HVAC systems with new, higher-efficiency systems, homeowners will consume less energy, save costs, and reduce their carbon footprints.

The sale of high-efficiency systems has long been a focus of ours, and we have invested in tools and technology intended to capture an increasingly richer sales mix over time. In addition, regulatory mandates will likely periodically increase the required minimum Seasonal Energy Efficiency Ratio rating, referred to as SEER, thus providing a catalyst for greater sales of higher-efficiency systems. Recently enacted regulations increased the current minimum SEER beginning in 2023 (generally, to 14 SEER from 13 SEER in the Northern U.S. and to 15 SEER from 14 SEER for the Southern U.S.).

Additionally, the American Innovation and Manufacturing Act of 2020 granted the U.S. Environmental Protection Agency the authority to regulate hydrofluorocarbon (“HFC”) refrigerants. Although HFCs were introduced as alternatives to ozone-depleting substances like chlorofluorocarbons and hydrochlorofluorocarbons, they are now recognized as potent greenhouse gases due to their high global warming potential (“GWP”). Consequently, a phasedown of HFC production and consumption by 85% over a 15-year period commenced on January 1, 2022, and regulations were established requiring HVAC systems to use refrigerants with a GWP under 750 by January 1, 2025. In response to these regulations, OEMs have begun the transition to new refrigerants. These regulations advance product innovation, improve homeowner energy efficiency, reduce the carbon footprint of end-users, and increase average selling prices over time. We offer a broad variety of systems that operate above the minimum SEER standards, ranging from base-level efficiency to systems that exceed 20 SEER. Based on estimates validated by independent sources, we averted an estimated 21.8 million metric tons of CO₂e emissions from January 1, 2020 to September 30, 2024 through the sale of replacement residential HVAC systems at higher-efficiency standards.

Federal Tax Credits and State Incentives

Demand for higher-efficiency products, such as variable-speed systems and heat pumps, is expected to increase due to the passage of the U.S. Inflation Reduction Act of 2022 (the “IRA”) in August 2022. This legislation is intended, in part, to promote the replacement of existing systems in favor of high-efficiency heat pump systems that reduce greenhouse gas emissions, as compared to older systems, and thereby combat climate change. Programs under the IRA include enhanced tax credits for homeowners who install qualifying HVAC equipment and tax deductions for owners of commercial buildings that are upgraded to achieve defined energy savings. The IRA also sets aside $4.3 billion for state-administered consumer rebate programs designed to promote energy savings for low and medium-income households, including HVAC systems. Further details, including qualifying products, specific programs, states participating, and other regulatory requirements contemplated by the IRA are still being finalized.

Impact of Hurricanes

Hurricane Helene interrupted sales and operations in several of our markets in the Southeastern U.S. during the last week of September 2024. The disruptions to our sales and operations did not have a significant impact on our results of operations for the third quarter or nine months ended September 30, 2024. We do not expect the disruptions related to this storm to have a material impact on future operations.

Hurricane Milton made landfall in Florida on October 10, 2024. We are currently evaluating the impact of that storm on our operations; however, we do not expect the disruptions caused by this storm to be material.

Critical Accounting Estimates

Management’s discussion and analysis of financial condition and results of operations is based upon the condensed consolidated unaudited financial statements included in this Quarterly Report on Form 10-Q, which have been prepared in accordance with U.S. generally accepted accounting principles. The preparation of these condensed consolidated unaudited financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the condensed consolidated unaudited financial statements, and the reported amount of revenues and expenses during the reporting period. Actual results may differ from these estimates under different assumptions or conditions. At least quarterly, management reevaluates its judgments and estimates, which are based on historical experience, current trends, and various other assumptions that are believed to be reasonable under the circumstances.

Our critical accounting estimates are included in our Annual Report on Form 10-K for the year ended December 31, 2023, as filed with the SEC on February 23, 2024. We believe that there have been no significant changes during the quarter ended September 30, 2024 to the critical accounting estimates disclosed in our Annual Report on Form 10-K for the year ended December 31, 2023.

New Accounting Standards

Refer to Note 1 to our condensed consolidated unaudited financial statements included in this Quarterly Report on Form 10-Q for a discussion of recently adopted, and to be adopted, accounting standards.

The following narratives reflect our acquisitions of Commercial Specialists, Inc. (“CSI”) in February 2024, Gateway Supply Company, Inc. (“GWS”) in September 2023, and Capitol District Supply Co., Inc. (“Capitol”) in March 2023. We did not acquire any businesses during the quarter ended September 30, 2024.

In the following narratives, computations and other information referring to “same-store basis” exclude the effects of locations closed, acquired, or locations opened, in each case during the immediately preceding 12 months, unless such locations are within close geographical proximity to existing locations. At both September 30, 2024 and 2023, three locations that we opened during the immediately preceding 12 months were near existing locations and were therefore included in “same-store basis” information.

Third Quarter of 2024 Compared to Third Quarter of 2023

Revenues


	Quarter Ended September 30,
(in millions)	2024		2023		Change
Revenues	$	2,160.0	$	2,126.8	$	33.2	2	%

The increase in revenues for the third quarter of 2024 included $37.5 million attributable to new locations acquired and $2.8 million from other locations opened during the preceding 12 months, offset by $2.6 million from locations closed.


	Quarter Ended September 30,
(in millions)	2024		2023		Change
Same-store sales	$	2,119.8	$	2,124.3	$	(4.5)	0%

The following table presents our revenues (excluding acquisitions) for the third quarter of 2024, as a percentage of sales, by major product lines and the related percentage change in revenues from the prior period:


	% of Sales
	2024			2023			% Change
HVAC equipment		71	%		70	%		1	%
Other HVAC products		25	%		26	%		(2	%)
Commercial refrigeration products		4	%		4	%		(4	%)

HVAC equipment sales reflect approximately flat sales of residential products, which is composed of unitary compressor-bearing systems, furnaces, and other indoor components (flat in U.S. markets and a 5% decrease in international markets), and a 6% increase in sales of commercial HVAC equipment (4% increase in U.S. markets and a 12% increase in international markets). The majority component of residential unitary compressor-bearing systems represent “ducted” systems produced by a variety of OEMs. Sales of ducted residential compressor-bearing systems decreased 2% during the third quarter of 2024, reflecting a 1% decrease in average selling price and a 1% decrease in unit volume. Domestic sales of residential unitary compressor-bearing systems remained approximately flat, reflecting a 3% decrease in average selling price and a 3% increase in units.

Gross Profit


	Quarter Ended September 30,
(in millions)	2024			2023			Change
Gross profit	$	566.2		$	566.9		$	(0.7	)	0	%
Gross margin		26.2	%		26.7	%

19 of 28

Gross profit margin declined 50 basis-points primarily due to the impact of pricing and sales mix for HVAC equipment in 2024 as compared to the same period in 2023.

Selling, General and Administrative Expenses


	Quarter Ended September 30,
(in millions)	2024			2023			Change
Selling, general and administrative expenses	$	326.4		$	319.8		$	6.6	2	%
Selling, general and administrative expenses as a percentage of revenues		15.1	%		15.0	%

Selling, general and administrative expenses increased 2% for the third quarter of 2024 primarily due to higher revenues. On a same-store basis, selling, general and administrative expenses were flat as compared to 2023.

Other Income

Other income of $10.4 million and $9.5 million for the third quarters of 2024 and 2023, respectively, represented our share of the net income of Russell Sigler, Inc. (“RSI”), in which we have a 38.4% equity interest.

Interest Income, Net

Interest income, net for the third quarter of 2024 increased $8.7 million, or 458%, primarily due to interest earned on cash and short-term investments and lower average borrowings under our revolving credit facility for the 2024 period as compared to the same period in 2023.

Income Taxes


	Quarter Ended September 30,
(in millions)	2024			2023			Change
Income taxes	$	55.4		$	54.1		$	1.3	2	%
Effective income tax rate		24.3	%		23.8	%

Income taxes represent a composite of the income taxes attributable to our wholly owned operations and income taxes attributable to our joint ventures with Carrier Global Corporation (“Carrier”), which are primarily taxed as partnerships for income tax purposes; therefore, Carrier is responsible for its proportionate share of income taxes attributable to its share of earnings from these joint ventures. The increase in the effective income tax rate was primarily due to higher foreign tax and lower tax credits in 2024 as compared to the same period in 2023.

Net Income Attributable to Watsco, Inc.

Net income attributable to Watsco, Inc. for the quarter ended September 30, 2024 was flat compared to the same period in 2023.

Nine Months Ended September 30, 2024 Compared to Nine Months Ended September 30, 2023

Revenues


	Nine Months Ended September 30,
(in millions)	2024		2023		Change
Revenues	$	5,864.4	$	5,680.6	$	183.8	3	%

The increase in revenues for the nine months ended September 30, 2024 included $145.0 million attributable to new locations acquired and $7.9 million from other locations opened during the preceding 12 months, offset by $5.4 million from locations closed.


	Nine Months Ended September 30,
(in millions)	2024		2023		Change
Same-store sales	$	5,711.4	$	5,675.1	$	36.3	1	%

20 of 28

The following table presents our revenues (excluding acquisitions) for the nine months ended September 30, 2024 as a percentage of sales, by major product lines and the related percentage change in revenues from the prior period:


	% of Sales
	2024			2023			% Change
HVAC equipment		70	%		69	%		3	%
Other HVAC products		26	%		27	%		(3	%)
Commercial refrigeration products		4	%		4	%		—

HVAC equipment sales reflect a 2% increase in residential products, which is composed of unitary compressor-bearing systems, furnaces, and other indoor components, (2% increase in U.S. markets and a 1% increase in international markets) and a 6% increase in sales of commercial HVAC equipment (4% increase in U.S. markets and an 11% increase in international markets). The majority component of residential unitary compressor-bearing systems represent “ducted” systems produced by a variety of OEMs. Sales of ducted residential compressor-bearing systems increased 1% during the nine months ended September 30, 2024, reflecting flat unit volume and a 1% increase in average selling price. Domestic sales of residential unitary compressor-bearing systems increased 2%, reflecting a 2% increase in units and flat average selling price.

Gross Profit


	Nine Months Ended September 30,
(in millions)	2024			2023			Change
Gross profit	$	1,576.6		$	1,577.7		$	(1.1	)	0	%
Gross margin		26.9	%		27.8	%

Gross profit margin declined 90 basis-points primarily due to the impact of pricing and sales mix for HVAC equipment in 2024 as compared to the same period in 2023. In addition, we estimate that marketing activities made by us to regain sales and market share lost in 2023 due to constrained availability of inventory from one of our primary OEM partners were dilutive to gross margin by approximately 30 basis-points for the nine months ended September 30, 2024.

Selling, General and Administrative Expenses


	Nine Months Ended September 30,
(in millions)	2024			2023			Change
Selling, general and administrative expenses	$	955.0		$	911.0		$	44.0	5	%
Selling, general and administrative expenses as a percentage of revenues		16.3	%		16.0	%

Selling, general and administrative expenses for the nine months ended September 30, 2024 increased primarily due to increased revenues and newly acquired locations. On a same-store basis, selling, general and administrative expenses increased 2% as compared to the same period in 2023 and, as a percentage of sales increased to 16.2% versus 16.0% in 2023, primarily due to increases in fixed costs and $5.3 million in nonrecurring items.

Other Income

Other income of $23.9 million and $20.4 million for the nine months ended September 30, 2024 and 2023, respectively, represents our share of the net income of RSI, in which we have a 38.4% equity interest.

Interest Income, Net

Interest income, net for the nine months ended September 30, 2024 increased $20.1 million, or 339%, primarily due to interest earned on cash and short-term investments and lower average outstanding borrowings under our revolving credit facility for the 2024 period as compared to the same period in 2023.

Income Taxes


	Nine Months Ended September 30,
(in millions)	2024			2023			Change
Income taxes	$	139.2		$	144.7		$	(5.5	)	(4	%)
Effective income tax rate		23.8	%		24.0	%

21 of 28

Income taxes represent a composite of the income taxes attributable to our wholly owned operations and income taxes attributable to our joint ventures with Carrier, which are primarily taxed as partnerships for income tax purposes; therefore, Carrier is responsible for its proportionate share of income taxes attributable to its share of earnings from these joint ventures. The decrease in the effective income tax rate was primarily due to higher share-based compensation deductions combined with lower earnings in 2024 as compared to the same period in 2023.

Net Income Attributable to Watsco, Inc.

Net income attributable to Watsco, Inc. for the nine months ended September 30, 2024 decreased $14.3 million, or 3%, compared to the same period in 2023. The decrease was primarily driven by higher selling, general and administrative expenses, partially offset by higher interest income, a reduction in income taxes, and a decrease in net income attributable to the non-controlling interest.

Liquidity and Capital Resources

We assess our liquidity in terms of our ability to generate cash to execute our business strategy and fund operating and investing activities, taking into consideration the seasonal demand for HVAC/R products, which peaks in the months of May through August. Significant factors that could affect our liquidity include the following:

•

cash needed to fund our business (primarily working capital requirements);

•

borrowing capacity under our revolving credit facility;

•

the timing and extent of sales of Common stock under our at-the-market offering program;

•

the ability to attract long-term capital with satisfactory terms;

•

acquisitions, including joint ventures and investments in unconsolidated entities;

•

dividend payments;

•

capital expenditures; and

•

the timing and extent of common stock repurchases.

Sources and Uses of Cash

We rely on cash flows from operations and borrowing capacity under our revolving credit agreement to fund seasonal working capital needs and for other general corporate purposes in the short-term and the long-term, including dividend payments (if and as declared by our Board of Directors), capital expenditures, business acquisitions, and development of our long-term operating and technology strategies. Additionally, we may also generate cash through the issuance and sale of our Common stock.

We believe that the combination of our operating cash flows, cash on hand, short-term cash investments, available borrowings under our revolving credit agreement, and funds available from sales of our Common stock under our 2024 ATM Program, each of which is described below, will be sufficient to meet our liquidity needs for the foreseeable future. However, there can be no assurance that our current sources of available funds will be sufficient to meet our cash requirements.

As of September 30, 2024, we had $294.4 million of cash and cash equivalents, of which $126.4 million was held by foreign subsidiaries. The repatriation of cash balances from our foreign subsidiaries could have adverse tax impacts or be subject to capital controls; however, these balances are generally available to fund the ordinary business operations of our foreign subsidiaries without legal restrictions. We also had $255.7 million of short-term cash investments consisting of certificates of deposit with varying maturities through March 2025.

Our access to funds under our revolving credit agreement depends on the ability of the syndicate banks to meet their respective funding commitments. Disruptions in the credit and capital markets could adversely affect our ability to draw on our revolving credit agreement and may also adversely affect the determination of interest rates, particularly rates based on the Secured Overnight Financing Rate (“SOFR”), which is one of the base rates under our revolving credit agreement. SOFR has limited historical data and is a secured lending rate, whereas our revolving credit agreement is unsecured and had primarily used LIBOR, an unsecured lending rate, as a base rate prior to the discontinuation of LIBOR in 2023. The use of SOFR as a base rate under our revolving credit agreement could give rise to uncertainties and volatility in the benchmark rates. Additionally, disruptions in the credit and capital markets could also result in increased borrowing costs or reduced borrowing capacity under our revolving credit agreement.

Working Capital

Working capital increased to $2,199.8 million at September 30, 2024 from $1,679.9 million at December 31, 2023, due to: (i) higher inventory balances in connection with our selling season; (ii) higher accounts receivable consistent with the seasonal increase in sales; and (iii) $255.7 million of short-term cash investments, which were offset by an increase in accounts payable consistent with the change in inventory.

Cash Flows

The following table summarizes our cash flow activity for the nine months ended September 30, 2024 and 2023 (in millions):


	2024			2023			Change
Cash flows provided by operating activities	$	394.2		$	263.3		$	130.9
Cash flows used in investing activities	$	(282.7	)	$	(28.1	)	$	(254.6	)
Cash flows used in financing activities	$	(25.1	)	$	(207.6	)	$	182.5

The individual items contributing to cash flow changes for the periods presented are detailed in the condensed consolidated unaudited statements of cash flows contained in this Quarterly Report on Form 10-Q.

Operating Activities

Net cash provided by operating activities in 2024 as compared to 2023 was higher primarily due to the timing of vendor payments partially offset by an increase in inventory.

Investing Activities

Net cash used in investing activities increased primarily due to the purchase of $255.7 million of short-term cash investments in 2024.

Financing Activities

Net cash used in financing activities decreased primarily due to higher net proceeds from the sale of Common stock under our 2021 ATM Program (as defined below), a portion of which was used for short-term cash investments, partially offset by an increase in dividends paid and repayments under our revolving credit agreement in 2024.

Revolving Credit Agreement

We maintain an unsecured, five-year $600.0 million syndicated multicurrency revolving credit agreement, which may be used for, among other things, funding seasonal working capital needs and for other general corporate purposes, including acquisitions, dividends (if and as declared by our Board of Directors), capital expenditures, stock repurchases, and issuances of letters of credit. The revolving credit facility has a seasonal component from October 1 to March 31, during which the borrowing capacity may be reduced to $500.0 million at our discretion (which effectively reduces fees payable in respect of the unused portion of the commitment). Included in the revolving credit facility are a $125.0 million swingline loan sublimit, a $10.0 million letter of credit sublimit, a $75.0 million alternative currency borrowing sublimit, and an $10.0 million Mexican borrowing subfacility. The revolving credit agreement matures on March 16, 2028.

At September 30, 2024, there was no outstanding balance under the revolving credit agreement. At December 31, 2023, $15.4 million was outstanding under the revolving credit agreement. The revolving credit agreement contains customary affirmative and negative covenants, including financial covenants with respect to consolidated leverage and interest coverage ratios, and other customary restrictions. We believe we were in compliance with all covenants at September 30, 2024.

At-the-Market Offering Program

During the quarter ended March 31, 2024, we issued and sold 712,000 shares of Common stock under the 2021 ATM Program for net proceeds of $281.8 million. We used the proceeds to pay off outstanding debt under our revolving credit agreement and purchased short-term cash investments with the remainder. In aggregate, $298.5 million of Common stock was sold under the 2021 ATM Program.

On May 3, 2024, we executed an amended and restated sales agreement with Baird (the “2024 ATM Program”), which enables the further issuance of up to $400.0 million of Common stock. At September 30, 2024, $400.0 million was available for sale under the 2024 ATM Program. The offer and sale of shares under the 2024 ATM Program were registered under the Securities Act pursuant to our automatically effective shelf registration statement on Form S-3 (File No. 333-260758) that expires on November 4, 2024 and for which we plan to file a replacement automatically effective shelf registration statement on Form S-3 immediately following the filing of this Quarterly Report on Form 10-Q.

23 of 28

Purchase Obligations

At September 30, 2024, we were obligated under various non-cancelable purchase orders with our key suppliers for goods aggregating approximately $460.0 million, with approximately $250.0 million attributable to Carrier and its affiliates. These purchase obligations represent commitments under purchase orders for goods in the ordinary course of business that are enforceable and legally binding with defined terms as to price, quantity, and delivery.

Investment in Unconsolidated Entity

Carrier Enterprise I, one of our joint ventures with Carrier, in which we have an 80% controlling interest, has a 38.4% ownership interest in RSI, an HVAC distributor operating from 35 locations in the Western U.S. Our proportionate share of the net income of RSI is included in other income in our condensed consolidated unaudited statements of income.

Carrier Enterprise I is a party to a shareholders’ agreement (the “Shareholders’ Agreement”) with RSI and its shareholders, consisting of five Sigler second generation family siblings and their affiliates, who collectively own 55.4% of RSI (the “RSI Majority Holders”) and certain next-generation Sigler family members and an employee, who collectively own 6.2% of RSI (the “RSI Minority Holders” and, together with the RSI Majority Holders, the “RSI Shareholders”). Pursuant to the Shareholders’ Agreement, the RSI Shareholders have the right to sell, and Carrier Enterprise I has the obligation to purchase, their respective shares of RSI for a purchase price determined based on the higher of book value or a multiple of EBIT, the latter of which Carrier Enterprise I used to calculate the price for its 38.4% investment held in RSI. The RSI Shareholders may transfer their respective shares of RSI common stock only to members of the Sigler family or to Carrier Enterprise I, and, at any time from and after the date on which Carrier Enterprise I owns 85% or more of RSI’s outstanding common stock, it has the right, but not the obligation, to purchase from the RSI Shareholders the remaining outstanding shares of RSI common stock. At September 30, 2024, using the criteria set forth in the Shareholders’ Agreement, the valuation of the RSI Shareholders’ RSI common stock was approximately $477.0 million.

On July 28, 2023, Watsco, Carrier Enterprise I, and the RSI Majority Holders entered into an agreement that (1) provides Carrier Enterprise I the discretion, but not the obligation, to fund up to 80% of any purchase from the RSI Majority Holders of their RSI common stock, as required under the Shareholders’ Agreement, using Watsco Common stock (the “Offered Shares”), (2) provides that any Offered Shares actually issued would be valued based on the average volume-weighted average price of Watsco’s Common stock for the ten trading days immediately preceding the payment date for the applicable RSI shares, and (3) limits the amount of RSI shares that may be collectively sold by the RSI Majority Holders to Carrier Enterprise I under the Shareholders’ Agreement to $125.0 million during any rolling 12-month period. We have not issued or sold any Offered Shares, and there is no assurance that we will issue and sell any Offered Shares, nor is the number of Offered Shares that may be issued and sold currently determinable.

We believe that our operating cash flows, cash on hand, short-term cash investments or funds available for borrowing under our revolving credit agreement, or use of the 2024 ATM Program would be sufficient to purchase any additional ownership interests in RSI for cash pursuant to the agreement described in the preceding paragraph.

Acquisitions

On February 1, 2024, one of our wholly owned subsidiaries acquired CSI, a distributor of HVAC products with annual sales of approximately $13.0 million, operating from two locations in Kentucky and Ohio. Consideration for the purchase consisted of $6.0 million in cash, 1,904 shares of Common stock having a fair value of $0.8 million, and $0.6 million for repayment of indebtedness, net of cash acquired of $1.4 million.

On September 1, 2023, we acquired substantially all the assets and assumed certain of the liabilities of GWS, a plumbing and HVAC distributor with annual sales of approximately $180.0 million, operating from 16 locations in South Carolina and North Carolina. Consideration for the net purchase price consisted of $4.0 million in cash, net of cash acquired of $3.1 million, and 280,215 shares of Common stock having a fair value of $101.6 million, net of a discount for lack of marketability.

On March 3, 2023, one of our wholly owned subsidiaries acquired Capitol, a distributor of plumbing and air conditioning and heating products with annual sales of approximately $13.0 million, operating from three locations in New York. Consideration for the purchase consisted of $1.2 million in cash, net of cash acquired of $0.1 million, and $1.9 million for repayment of indebtedness.

We continually evaluate potential acquisitions and/or joint ventures and investments in unconsolidated entities. We routinely hold discussions with several acquisition candidates. Should suitable acquisition opportunities arise that would require additional financing, we believe our financial position and earnings history provide a sufficient basis for us to either obtain additional debt financing at competitive rates and on reasonable terms or raise capital through the issuance of equity securities.

24 of 28

Common Stock Dividends

We paid cash dividends of $7.85 and $7.35 per share on both Common and Class B common stock during the nine months ended September 30, 2024 and 2023, respectively. On October 1, 2024, our Board of Directors declared a regular quarterly cash dividend of $2.70 per share on both Common and Class B common stock that was paid on October 31, 2024 to shareholders of record as of October 16, 2024. Future dividends and/or changes in dividend rates are at the sole discretion of the Board of Directors and depend upon factors including, but not limited to, cash flow generated by operations, profitability, financial condition, cash requirements, prospects, and other factors deemed relevant by our Board of Directors.

Dividend Reinvestment Plan

On March 29, 2024, we implemented the Watsco, Inc. Dividend Reinvestment Plan (the “Plan”), under which existing shareholders may, in accordance with the Plan, acquire shares of Common stock or Class B common stock, as applicable (collectively “common stock”), by reinvesting all or a portion of the cash dividends paid on such shareholders’ shares of common stock. The Plan has been registered under the Securities Act pursuant to our automatically effective shelf registration statement on Form S-3 (File No. 333-260758).

During the quarter and nine months ended September 30, 2024, we issued 13,394 and 13,398 shares of common stock under the Plan, respectively.

Company Share Repurchase Program

In September 1999, our Board of Directors authorized the repurchase, at management’s discretion, of up to 7,500,000 shares of common stock in the open market or via private transactions. Shares repurchased under the program are accounted for using the cost method and result in a reduction of shareholders’ equity. We last repurchased shares under this plan in 2008. In aggregate, 6,370,913 shares of Common and Class B common stock have been repurchased at a cost of $114.4 million since the inception of the program. At September 30, 2024, there were 1,129,087 shares remaining authorized for repurchase under the program. In considering any further stock repurchases under our repurchase program, we intend to evaluate the impact of the 1% excise tax on stock repurchases that became effective on January 1, 2023.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

There have been no material changes to the information regarding market risk provided in Item 7A, Quantitative and Qualitative Disclosures about Market Risk, of our Annual Report on Form 10-K for the year ended December 31, 2023.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) that are, among other things, designed to ensure that information required to be disclosed by us under the Exchange Act is accumulated and communicated to management, including our Chief Executive Officer (“CEO”), Executive Vice President (“EVP”), and Chief Financial Officer (“CFO”), to allow for timely decisions regarding required disclosure and appropriate SEC filings.

Our management, with the participation of our CEO, EVP and CFO, evaluated the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report, and, based on that evaluation, our CEO, EVP and CFO concluded that our disclosure controls and procedures were effective, at a reasonable assurance level, at and as of such date.

Changes in Internal Control over Financial Reporting

We continuously seek to improve the efficiency and effectiveness of our internal controls. This results in refinements to processes throughout the Company. However, there were no changes in our internal controls over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended September 30, 2024, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

BASIS OF PRESENTATION (Policies)	9 Months Ended
BASIS OF PRESENTATION (Policies)	Sep. 30, 2024
Accounting Policies [Abstract]
Basis of Consolidation	Basis of Consolidation Watsco, Inc. (collectively with its subsidiaries, “Watsco,” the “Company,” “we,” “us,” or “our”) was incorporated in Florida in 1956 and is the largest distributor of air conditioning, heating and refrigeration equipment and related parts and supplies (“HVAC/R”) in the HVAC/R distribution industry in North America. The accompanying September 30, 2024 interim condensed consolidated unaudited financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and note disclosures normally included in the annual financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to those rules and regulations, but we believe the disclosures made are adequate to make the information presented not misleading. In the opinion of management, all adjustments, consisting of normal and recurring adjustments, necessary for a fair presentation have been included in the condensed consolidated unaudited financial statements included herein. These statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our 2023 Annual Report on Form 10-K. The condensed consolidated unaudited financial statements include the accounts of Watsco, all of its wholly owned subsidiaries, the accounts of four joint ventures with Carrier Global Corporation, which we refer to as Carrier, in which we have a controlling interest, the accounts of Carrier InterAmerica Corporation and Carrier (Puerto Rico), Inc., in each of which we have an 80% controlling interest, and Carrier has a 20% non-controlling interest, and our 38.4% investment in Russell Sigler, Inc., which is accounted for under the equity method of accounting. All significant intercompany balances and transactions have been eliminated in consolidation. The results of operations for the quarter and nine months ended September 30, 2024 are not necessarily indicative of the results to be expected for the year ending December 31, 2024. Sales of residential central air conditioners, heating equipment, and parts and supplies are seasonal. Furthermore, profitability can be impacted favorably or unfavorably based on weather patterns, particularly during the Summer and Winter selling seasons. Demand related to the residential central air conditioning replacement market is typically highest in the second and third quarters, and demand for heating equipment is usually highest in the first and fourth quarters. Demand related to the new construction sectors throughout most of the markets we serve tends to be fairly evenly distributed throughout the year and depends largely on housing completions and related weather and economic conditions.
Short-Term Cash Investments	Short-Term Cash Investments Short-term cash investments consist of certificates of deposit that have varying maturities through March 2025.
Equity Method Investments	Equity Method Investments Investments in which we have the ability to exercise significant influence, but do not control, are accounted for under the equity method of accounting and are included in investment in unconsolidated entity in our condensed consolidated unaudited balance sheets. Under this method of accounting, our proportionate share of the net income or loss of the investee is included in other income in our condensed consolidated unaudited statements of income. The excess, if any, of the carrying amount of our investment over our ownership percentage in the underlying net assets of the investee is attributed to certain fair value adjustments with the remaining portion recognized as goodwill.
Use of Estimates	Use of Estimates The preparation of condensed consolidated unaudited financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated unaudited financial statements and the reported amounts of revenues and expenses for the reporting period. Significant estimates include valuation reserves for accounts receivable, net realizable value adjustments to inventories, income taxes, reserves related to loss contingencies and the valuation of goodwill, indefinite-lived intangible assets, and long-lived assets. While we believe that these estimates are reasonable, actual results could differ from such estimates.
Recently Adopted Accounting Standards	Recently Adopted Accounting Standards Segment Reporting In September 2023, the Financial Accounting Standards Board (“FASB”) issued guidance that enhances segment reporting primarily by expanding the disclosures about significant segment expenses. Under the new standard, an entity will be required to disclose significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”), how the CODM assesses segment performance and decides how to allocate resources, the title and position of the CODM, and certain other disclosures. This guidance is effective prospectively and is effective for annual periods beginning after December 15, 2023 and for interim periods beginning after December 15, 2024. The adoption of this guidance on January 1, 2024 did not have a material impact on our consolidated financial statements.
Recently Issued Accounting Standards	Recently Issued Accounting Standards Not Yet Adopted Income Taxes In December 2023, the FASB issued guidance that enhances annual income tax disclosures primarily by disaggregating the existing disclosures related to the effective tax rate reconciliation and income taxes paid. Under the new guidance, an entity will be required to disclose specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. An entity will also be required to disclose the amount of income taxes paid disaggregated by federal, state, and foreign, and by individual jurisdictions equal to or greater than five percent of total income taxes paid. This guidance is effective prospectively and is effective for annual periods beginning after December 15, 2024. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements. Climate Disclosures In March 2024, the Securities and Exchange Commission (“SEC”) adopted rules to enhance and standardize disclosures related to the impacts and risks of climate-related matters. Under the new rules, an entity will be required to disclose information about climate-related risks that have materially impacted, or are likely to have a material impact, on its business strategy, results of operations, or financial condition. In addition, certain disclosures related to severe weather events, other natural conditions, and greenhouse gas emissions will be required in the audited financial statements. These rules are effective prospectively and are effective for annual periods beginning with the year ending December 31, 2025. On April 4, 2024, the SEC announced that it will stay t he implementation of its final rules pending the results of a legal challenge. We will continue to assess the impact of these rules on our consolidated financial statements while the stay is in place.
