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 June 30, 2024 interim condensed consolidated unaudited financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission.

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.

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.

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 or greater than five percent of total income taxes paid.

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.
