(In thousands, except share and per share data)

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 March 31, 2026 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 2025 Annual Report on Form 10-K.

The condensed consolidated unaudited financial statements include (i) the accounts of Watsco and its wholly owned subsidiaries, (ii) the accounts offive U.S. joint ventures and their subsidiaries with Carrier Global Corporation, which we refer to as Carrier, in which we have an 80% controlling interest and Carrier has a 20% non-controlling interest, (iii) the accounts of a Canadian joint venture with Carrier, in which we have a 60% controlling interest and Carrier has a 40% non-controlling interest, and (iv) a 38.4% investment in Russell Sigler, Inc. (“RSI”), owned by one of the Carrier joint ventures that 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 ended March 31, 2026 are not necessarily indicative of the results to be expected for the year ending December 31, 2026. 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 new construction 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.

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

Measurement of Credit Losses

In July 2025, the FASB issued amended guidance to provide the option to elect a practical expedient for the application of the expected credit loss model. Under this practical expedient, an entity can assume that the current conditions it has applied in determining credit loss allowances for current accounts receivable and current contract assets remain unchanged for the remaining life of those assets. This

9 of 27 amendment is effective for annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods, with early adoption permitted. Theadoption of this guidance on January 1, 2026 didnot have a material impact on our condensed consolidated unaudited financial statements.

Recently Issued Accounting Standards Not Yet Adopted

Expense Disaggregation

In November 2024, the FASB issued guidance that requires entities to disclose additional information about certain expenses in the notes to the financial statements. This guidance is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, with early adoption permitted. We are evaluating the impact of adopting this new guidance on our consolidated financial statements.

Internal Use Software

In September 2025, the FASB issued updated guidance on the accounting for internal use software costs. The updated guidance removes all references to project stages to be neutral to different software development methods and clarifies the threshold entities apply to begin capitalizing costs. This guidance is effective for annual reporting periods beginning after December 15, 2027 and interim reporting periods within those annual reporting periods. We are evaluating the impact of adopting this guidance on our consolidated financial statements.

Interim Reporting

In December 2025, the FASB issued guidance that clarifies the scope and requirements for interim financial statement disclosures. The guidance create a comprehensive list of required interim disclosures and introduce a disclosure principle requiring entities to disclose in interim periods any event or change since the previous year end that has had a material effect on the entity. This guidance may be applied prospectively or retrospectively and is effective for interim reporting periods within annual periods beginning after December 15, 2027, with early adoption permitted. We are evaluating the impact of adopting this guidance on our consolidated financial statements.

REVENUES

Disaggregation of Revenues

The following table presents our revenues disaggregated by primary geographical regions and major product lines within our single reporting segment:

10 of 27

EARNINGS PER SHARE

The following table presents the calculation of basic and diluted earnings per share for our common stock:

Diluted earnings per share for our Common stock assumes the conversion of all our Class B common stock into Common stock as of the beginning of the fiscal year; therefore, no allocation of earnings to Class B common stock is required. At March 31, 2026 and 2025, our outstanding Class B common stock was convertible into 3,383,702 and 3,325,027 shares of our Common stock, respectively.

OTHER COMPREHENSIVE (LOSS) INCOME

Other comprehensive (loss) income consists of the foreign currency translation adjustment associated with our Canadian operations’ use of the Canadian dollar as their functional currency.

The change in accumulated other comprehensive loss, net of tax, was as follows:

ACQUISITIONS

Southern Ice Equipment Distributors, Inc.

On May 1, 2025, one of our wholly owned subsidiaries acquired Southern Ice Equipment Distributors, Inc., a distributor of food service and ice machine equipment, parts and supplies, operating from seven locations in Arizona, Arkansas, Louisiana, Mississippi, New Mexico, and Texas. Consideration for the purchase consisted of$14,150 in cash, net of cash acquired of$699, and 7,400 shares of Common stock having a fair value of$3,133 net of a discount for lack of marketability. The purchase price resulted in the recognition of$7,872 of goodwill and intangibles. The fair value of the identified intangible assets was$3,651 and consisted of$2,795 in trade names and distribution rights and$856 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.

Hawkins HVAC Distributors, Inc.

On April 1, 2025, one of our wholly owned subsidiaries acquired Hawkins HVAC Distributors, Inc., a distributor of residential HVAC equipment and supplies, operating fromtwo locations in North Carolina and South Carolina. Consideration for the purchase consisted of$2,452 in cash, net of cash acquired of$368. The purchase price resulted in the recognition of$269 in goodwill. The tax basis of such goodwill is deductible for income tax purposes over 15 years.

W.L. Lashley & Associates, Inc.

On January 3, 2025, Carrier Enterprise I, one of our joint ventures with Carrier, in which we have an 80% controlling interest, acquired Lashley, a distributor of commercial HVAC supplies, operating fromone location in Houston, Texas. Consideration for the purchase consisted of$3,662 in cash, net of cash acquired of$837,1,036 shares of Common stock having a fair value of$493, and$838 for repayment of indebtedness. Carrier contributed$999 cash to Carrier Enterprise I in connection with the acquisition of Lashley. The purchase price resulted in the recognition of$3,064 in goodwill. 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.

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 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 forward contract not designated as a hedging instrument at March 31, 2026, the total notional value of which was$8,900. Such contract expired in April 2026.

We recognized losses of$250 and$153 from foreign currency forward contracts not designated as hedging instruments in our condensed consolidated unaudited statements of income for the quarters ended March 31, 2026 and 2025, respectively.

FAIR VALUE MEASUREMENTS

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

12 of 27

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:

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

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

Derivative financial instruments – these derivatives are foreign currency forward 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.

SHAREHOLDERS’ EQUITY

Dividend Reinvestment Plan

In March 2024, we implemented the Watsco, Inc. Dividend Reinvestment Plan (the “DRIP”), under which existing shareholders may, in accordance with the DRIP, acquire up to an aggregate of 300,000 shares of each of Common and Class B common stock, as applicable, by reinvesting all or a portion of the cash dividends paid on such shareholders’ shares of common stock. The DRIP 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. 333-282975). During the quarters ended March 31, 2026 and 2025,9,890 and 13,942 shares of our common stock, respectively, were issued under the DRIP.

At-the-Market Offering Program

On May 3, 2024, we entered into an amended and restated sales agreement with Robert W. Baird & Co. Inc. (the “2024 ATM Program”), which enables the issuance and sale of Common stock for a maximum aggregate offering amount of up to $400,000. At March 31, 2026, $400,000 was available for sale under the 2024 ATM Program. The offer and sale of shares under the 2024 ATM Program have been registered under the Securities Act pursuant to our automatically effective shelf registration statement on Form S-3 (File No. 333-282975).

Common Stock Dividends

We paid cash dividends of$3.00 and$2.70 per share on common stock during the three months ended March 31, 2026 and 2025, respectively.

Restricted Stock

During the quarter ended March 31, 2026,1,431 shares of common stock with an aggregate fair market value of$564 were withheld as payment in lieu of cash to satisfy tax withholding obligations in connection with the vesting of restricted stock. These shares were retired upon delivery.

Exercise of Stock Options

Cash received from Common stock issued upon the exercise of stock options during the quarters ended March 31, 2026 and 2025 was$5,114 and$10,398, respectively.

During the quarter ended March 31, 2026,589 shares of Common stock with an aggregate fair market value of$242 were withheld as payment in lieu of cash for stock option exercises and related tax withholdings. These shares were retired upon delivery.

Employee Stock Purchase Plan

During the quarters ended March 31, 2026 and 2025, we received proceeds of$648 and$651, respectively, for shares of our Common stock purchased under our employee stock purchase plan.

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

13 of 27 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.

Since 2009, we have been a party to an agreement (the “Agreement”) with Gree Electric Appliances, Inc. of Zhuhai, China (“Gree”) that, among other things, provides us with exclusive distribution rights for certain Gree-branded products in the United States. A dispute has arisen between Gree and Watsco as to whether the automatic renewal provisions of the Agreement extended the term of the Agreement for an additional 10 years before the prior term was to end in January 2026.

In March 2026, Gree filed a complaint for declaratory judgment in Florida’s Circuit Court for Miami-Dade County, seeking a judicial determination that the Agreement did not renew for a successive term and has in fact been terminated. In April 2026, we filed our answer and affirmative defenses to Gree’s complaint, and we interposed counterclaims against Gree to enforce our rights under the Agreement, including seeking a judicial determination that the Agreement renewed for an additional 10-year period and remains in full force and effect, and an award for any damages resulting from Gree’s improper purported termination or non-renewal of the Agreement and Gree’s other related acts. We intend to vigorously prosecute our counterclaims and affirm our position that the Agreement automatically renewed for an additional 10-year period, and to vigorously defend against Gree’s assertion that the Agreement was not renewed.

We continue to purchase Gree-branded products from Gree, and Gree has continued to sell products to us despite the unresolved status of the dispute and the Agreement. Any future material interruption of the business arrangement with Gree under the Agreement could temporarily affect certain of our subsidiaries and may have an adverse impact on our consolidated financial results. For the 12-month period ended March 31, 2026, less than 3% of our consolidated revenues were from the sale of Gree-branded products.

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$5,976 and$4,871 at March 31, 2026 and December 31, 2025, respectively, were established related to such programs and are included in accrued expenses and other current liabilities in our condensed consolidated unaudited balance sheets.

RELATED PARTY TRANSACTIONS

Purchases from Carrier and its affiliates comprised 63% and 65% of all inventory purchases made during the quarters ended March 31, 2026 and 2025, respectively. At March 31, 2026 and December 31, 2025, approximately$145,000 and$115,000, 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 ended March 31, 2026 and 2025 included approximately$15,000 and$19,000, 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.

A member of our Board of Directors is a Senior Chairman of Greenberg Traurig, P.A., which serves as our principal outside counsel for compliance and acquisition-related legal services. During the quarters ended March 31, 2026 and 2025, fees for services performed were$15 and$22, respectively, and$29 and$19 was payable at March 31, 2026 and December 31, 2025, respectively.

SEGMENT REPORTING

We haveone operating and reporting segment: HVAC/R distribution. This sole line of business focuses exclusively on the distribution of air conditioning, heating, and refrigeration equipment and related parts and supplies. Our single reportable segment entity is managed on a consolidated basis, with the CEO serving as the chief operating decision maker (“CODM”). On a monthly basis, the CODM reviews financial information presented on a consolidated basis, as reported in theconsolidated statements of income, and uses consolidated operating income and net income to assess performance and allocate resources. The CODM does not receive information that is disaggregated or presented outside of the consolidated statement of income.

Significant expenses within operating income and net income include cost of sales and selling, general and administrative expenses, which are each separately presented in the consolidated statements of income. Other segment items within net income include interest and income taxes.

Our operations are primarily within the United States, including Puerto Rico, Canada, and Mexico. Products are also sold from the United States on an export-only basis to portions of Latin America and the Caribbean Basin. See Note 2 for revenues disaggregated by geographical regions and major product line.

SUBSEQUENT EVENT

On April 23, 2026, we entered into an asset purchase agreement (the “Purchase Agreement”) together with Jackson Supply Company, a Texas corporation (“Jackson”), our wholly owned subsidiary, Jackson Supply LLC (“Buyer”), and the other parties thereto, pursuant to which Buyer has agreed to purchase the assets, and assume certain of the liabilities, comprising the HVAC distribution business of Jackson (the “Business”). Jackson is an HVAC distributor, with annual sales of approximately $230,000. Jackson was founded in 1972 and serves approximately 5,000 customers from 25 locations across Sunbelt markets in Texas, Louisiana, Tennessee, Alabama, Mississippi, Oklahoma, and Arizona.

Pursuant to the Purchase Agreement, upon consummation of the contemplated transaction (the “Closing”), we have agreed to issue to Jackson a number of shares of Common stock equal to $198,000, net of the Business’ debt and transaction expenses, divided by the daily volume-weighted average price of the Common stock on the New York Stock Exchange for the 10 most recent trading days immediately preceding the Closing, of which $25,000 of such shares will be held in escrow for a period of up to 12 months following the Closing in connection with customary purchase price adjustments and indemnification obligations of Jackson. We currently expect Closing to occur in the second quarter of 2026, subject to the satisfaction or waiver of customary closing conditions, including regulatory approval.
