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.

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

18-year

period. The tax basis of the acquired goodwill recognized is not deductible for income tax purposes.

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.

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.

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.

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

Class

B common stock was convertible into 3,237,527 and 3,229,118 shares of our Common stock, respectively.

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.

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.

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.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

BASIS OF PRESENTATION

Sep. 30, 2024

BASIS OF PRESENTATION

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.
