This discussion summarizes the significant factors affecting our consolidated operating results, financial condition and liquidity for the year ended December 31, 2025. This discussion should be read in conjunction with the information contained in Item 1A, “Risk Factors” and the consolidated financial statements, including the notes thereto, included under Item 8, “Financial Statements and Supplementary Data” of this Annual Report on Form 10-K for the year ended December 31, 2025.

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 December 31, 2025, we operated from 695 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.

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.

Tariffs

We continue to monitor macroeconomic conditions and recent U.S. trade policy announcements, which have implications for the various OEMs and vendors that comprise our supply chain. Many HVAC equipment and component manufacturers, including Carrier Global Corporation (“Carrier”) and Rheem Manufacturing Company, source component parts from China and Mexico or assemble significant portions of residential and light-commercial products in Mexico, exposing them to tariff and inflationary pressures. In response, our OEM partners and suppliers have implemented varied price actions. To mitigate these effects, we have taken pricing actions, leveraging our technology platforms to efficiently adapt to changing conditions. While the long-term impact of tariffs remains uncertain, we believe that our focus on the HVAC replacement market remains a stabilizing factor, given the essential role of these products in providing comfort and healthy environments for homeowners and businesses. However, if additional restrictions, amendments to existing trade agreements, such as the United States-Mexico-Canada Agreement, or further tariff increases on goods sourced from or assembled in Mexico and China, significantly raise our product costs, then we may need to increase our prices further, which could lead to reduced sales, customer loss, and potential harm to our business.

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 U.S. Department of Energy (“DOE”), heating and air conditioning accounts for roughly half of household energy consumption in the U.S. 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 U.S. 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 increased sales of higher-efficiency systems. The Company expects these regulations to reduce the carbon footprint of end-users and increase average selling prices over time, subject to customary risks of quality, availability, and performance of new HVAC systems.

The American Innovation and Manufacturing Act of 2020 granted the U.S. Environmental Protection Agency (the “EPA”) the authority to regulate HFC refrigerants. Although HFCs were introduced as alternatives to ozone-depleting substances like chlorofluorocarbons and hydrochlorofluorocarbons, they are now recognized greenhouse gases that impact climate change due to their high global warming potential (“GWP”). Consequently, a required 85% phasedown of HFC production and consumption over a 15-year period commenced on January 1, 2022 (40% of which was completed in 2024). Further regulations were implemented that (1) restricted the use of high-GWP refrigerants in new HVAC systems (the “410A Systems”) manufactured after December 31, 2024 and (2) established a timeline over which the sales and installation of 410A Systems by distributors and contractors were permitted. Beginning in late 2024, the Company, in collaboration with its OEMs and in anticipation of the change, began to transition its inventory to the new lower-GWP HVAC systems (the “A2L Systems”) and phase-out the 410A Systems. The regulations permitted the sale and installation of matching 410A HVAC Systems (i.e., outdoor and indoor components that are installed together) through December 31, 2025, after which the outdoor or indoor components may be separately sold and installed thereafter without limitation or expiration. On October 3, 2025, the EPA proposed changes to this regulation that would eliminate or extend the December 31, 2025 installation deadline (thus allowing the continued sale) of matching 410A Systems beyond that date. As of the date of this filing, a final rule has not been issued. On December 23, 2025, the EPA issued an enforcement statement deprioritizing enforcement of the installation ban for affected 410A Systems that became effective on January 1, 2026. The Company continues to sell components of 410A Systems separately as permitted under the regulations and will assess its ability of offering matching 410A Systems once the EPA finalizes the rule change, which is expected in early 2026.

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 26.2 million metric tons of CO2e emissions from January 1, 2020 to December 31, 2025 through the sale of replacement residential HVAC systems at higher-efficiency standards.

Federal Tax Credits

The U.S. Inflation Reduction Act of 2022 (the “IRA”) was intended, in part, to promote the replacement of existing legacy systems in favor of high-efficiency heat pump systems that reduce greenhouse gas emissions, as compared to older systems, and thereby combat climate change. According to the DOE, heat pumps can reduce electricity use for heating by approximately 65% as compared to gas furnaces. 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. However, the act commonly referred to as the One Big Beautiful Bill, which was signed into law on July 4, 2025, eliminated the IRA’s previously enacted tax credits for HVAC systems, making such credits unavailable after December 31, 2025.

Critical Accounting Estimates

Management’s discussion and analysis of financial condition and results of operations is based upon the consolidated financial statements, which have been prepared in accordance with U.S. Generally Accepted Accounting Principles. The preparation of these consolidated 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 consolidated 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 significant accounting policies are discussed in Note 1 to our audited consolidated financial statements included in this Annual Report on Form 10-K. Management believes that the following accounting estimates include a higher degree of judgment and/or complexity and are reasonably likely to have a material impact on our financial condition or results of operations and, thus, are considered critical accounting estimates. Management has discussed the development and selection of critical accounting estimates with the Audit Committee of the Board of Directors and the Audit Committee has reviewed the disclosures relating to critical accounting estimates.

Allowance for Doubtful Accounts

An allowance for doubtful accounts is maintained for estimated losses resulting from the inability of customers to make the required payments. We typically do not require our customers to provide collateral. Accounting for doubtful accounts contains uncertainty because management must use judgment to assess the collectability of these accounts. When preparing these estimates, management considers several factors, including the aging of a customer’s account, past transactions with customers,

creditworthiness of specific customers, historical trends, and other information, including potential impacts of business and economic conditions. Our business and our customers’ businesses are seasonal. Sales are lowest during the first and fourth quarters, and past due accounts receivable balances as a percentage of total trade receivables generally increase during these quarters. We review our accounts receivable reserve policy periodically, reflecting current risks, trends, and changes in industry conditions.

The allowance for doubtful accounts was $14.6 million and $15.8 million at December 31, 2025 and 2024, respectively, a decrease of $1.2 million. Accounts receivable balances greater than 90 days past due as a percentage of accounts receivable at December 31, 2025 decreased to 1.4% from 1.6% at December 31, 2024. These decreases were primarily attributable to an improvement in the underlying quality of our accounts receivable portfolio at December 31, 2025.

Although we believe the allowance for doubtful accounts is sufficient, a decline in economic conditions could lead to the deterioration in the financial condition of our customers, resulting in an impairment of their ability to make payments and requiring additional allowances that could materially impact our consolidated results of operations. We believe our exposure to customer credit risk is limited due to the large number of customers comprising our customer base and their dispersion across many different geographical regions. Additionally, we mitigate credit risk through credit insurance programs.

Inventories

Inventory adjustments are established to report inventories at the lower of cost using the weighted-average and the first-in, first-out methods, or net realizable value. As part of the valuation process, inventories are adjusted to reflect excess, slow-moving, and damaged goods. The valuation process contains uncertainty because management must make estimates and use judgment to determine the future salability of inventories. Inventory policies are reviewed periodically, reflecting current risks, trends, and changes in industry conditions. A reserve for estimated inventory shrinkage is maintained and reflects the results of cycle count programs and physical inventories. When preparing these estimates, management considers historical sell through of specific inventory, current and anticipated inventory levels, and current operating trends.

Valuation of Goodwill, Indefinite Lived Intangible Assets and Long-Lived Assets

The recoverability of goodwill is evaluated at least annually and when events or changes in circumstances indicate that the carrying amount may not be recoverable. We have one reporting unit that is subject to goodwill impairment testing. In performing the goodwill impairment test, we use a two-step approach. The first step compares the reporting unit’s fair value to its carrying value. If the carrying value exceeds the fair value, a second step is performed to measure the amount of impairment loss. The identification and measurement of goodwill impairment involves the estimation of the fair value of our reporting unit and contains uncertainty because management must use judgment in determining appropriate assumptions to be used in the measurement of fair value. On January 1, 2026, we performed our annual evaluation of goodwill impairment and determined that the estimated fair value of our reporting unit exceeded its carrying value.

The recoverability of indefinite lived intangibles and long-lived assets are also evaluated on an annual basis or more often if deemed necessary. Indefinite lived intangibles and long-lived assets not subject to amortization are assessed for impairment by comparing the fair value of the intangible asset or long-lived asset to its carrying amount to determine if a write-down to fair value is required. Our annual evaluation did not indicate any impairment of indefinite lived intangibles or long-lived assets.

The estimates of fair value of our reporting unit, indefinite lived intangibles, and long-lived assets are based on the best information available as of the date of the assessment and incorporate management’s assumptions about expected future cash flows and contemplates other valuation techniques. Future cash flows can be affected by changes in the industry, a declining economic environment, or market conditions. There have been no events or circumstances from the date of our assessments that would have had an impact on this conclusion. The carrying amounts of goodwill, intangibles, and long-lived assets were $1,460.3 million and $1,399.5 million at December 31, 2025 and 2024, respectively, an increase of $60.8 million, primarily related to higher renewal lease rates of our warehouse facilities. Although no significant impairment losses have been recorded to date, there can be no assurance that impairments will not occur in the future. An adjustment to the carrying value of goodwill, intangibles, and long-lived assets could materially adversely impact the consolidated results of operations.

Loss Contingencies

Accruals are recorded for various contingencies including self-insurance, legal proceedings, environmental matters, and other claims that arise in the normal course of business. The estimation process contains uncertainty because accruals are based on judgment, the probability of losses and, where applicable, the consideration of opinions of external legal counsel and actuarially determined estimates. Additionally, we record receivables from third party insurers when recovery has been determined to be probable.

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 self-insurance reserves are adequate. If actual claims or adverse development of loss reserves occur and exceed these estimates, additional reserves may be required and could materially impact the consolidated results of operations. The estimation process contains uncertainty since management must use judgment to estimate the ultimate cost that will be incurred to settle reported claims and unreported claims for incidents incurred but not reported as of the balance sheet date. Reserves in the amounts of $4.9 million and $6.2 million at December 31, 2025 and 2024, respectively, were established related to such insurance programs. The decrease in self-insurance reserves was primarily due to the settlement of claims during 2025.

Income Taxes

Income taxes are accounted for under the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial reporting basis and the tax basis of assets and liabilities at enacted tax rates expected to be in effect when such amounts are recovered or settled. The use of estimates by management is required to determine income tax expense, deferred tax assets, and any related valuation allowance and deferred tax liabilities. A valuation allowance of $14.2 million and $11.6 million was reflected in the Company’s balance sheet at December 31, 2025 and 2024, respectively. The increase was primarily attributable to the impact on U.S. deferred tax assets from share-based compensation deduction limitations related to the expansion of Internal Revenue Code Section 162(m). See Note 9 to our audited consolidated financial statements included in this Annual Report on Form 10-K. The valuation allowance is based on several factors including, but not limited to, estimates of future taxable income by jurisdiction in which the deferred tax assets will be recoverable. These estimates can be affected by several factors, including changes to tax laws, or possible tax audits, or general economic conditions, or competitive pressures that could affect future taxable income. Although management believes that the estimates are reasonable, the deferred tax asset and any related valuation allowance will need to be adjusted if management’s estimates of future taxable income differ from actual taxable income. An adjustment to the deferred tax asset and any related valuation allowance could materially impact the consolidated results of operations.

New Accounting Standards

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

Note: Due to rounding, percentages may not total 100.

The following narratives reflect our acquisitions of Southern Ice Equipment Distributors, Inc. (“SIE”) in May 2025, Hawkins HVAC Distributors, Inc. (“Hawkins”) in April 2025, W.L. Lashley & Associates, Inc. (“Lashley”) in January 2025, 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.

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 December 31, 2025 and 2024, three and two locations, respectively, that we opened during the immediately preceding 12 months were near existing locations and were therefore included in “same-store basis” information.

The table below summarizes the changes in our locations for 2025 and 2024:

2025 Compared to 2024

Revenues

The decrease in revenues for 2025 included $36.9 million attributable to acquired locations and $22.5 million from other locations opened during the preceding 12 months, offset by a reduction of $21.2 million from locations closed.

The following table presents our revenues for 2025, as a percentage of sales, by major product lines and the related percentage change in revenues from the prior year:

HVAC equipment sales comprise various products including, but not limited to, residential ducted and ductless systems, furnaces, and other indoor components, as well as commercial HVAC systems. Within HVAC equipment, sales of residential products declined 7% (reflecting a 7% decrease in U.S. markets and a 16% decrease in international markets) and sales of commercial products decreased 7% (reflecting a 7% decrease in U.S. markets and a 5% decrease in international markets). The largest component of residential sales are ducted compressor-bearing systems produced by a variety of OEMs. Sales of ducted residential compressor-bearing systems decreased 10% during the year ended December 31, 2025, reflecting an 18% decrease in unit volume and an 8% increase in average selling price. The lower unit volumes primarily resulted from a major regulatory-driven transition to new generation A2L refrigerant equipment and related disruptions, temperate weather conditions during our summer selling season, lower home building activity, and reduced consumer spending for replacement systems and upgrades.

Gross profit margin improved 120 basis-points primarily due to the impact of pricing and sales mix for HVAC equipment in 2025 as compared to 2024.

Selling, general and administrative expenses increased 3% as compared to 2024, primarily due to higher labor, facilities, and transportation costs partially associated with the A2L product transition, as well as the acquisition of Lashley, Hawkins, and SIE in 2025.

Other Income

Other income of $27.8 million and $30.5 million for 2025 and 2024, respectively, represented our share of the net income of Russell Sigler, Inc. (“RSI”), in which Carrier Enterprise I has a 38.4% equity interest. Carrier Enterprise I is one of our joint ventures with Carrier, in which we have an 80% controlling interest.

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 tax credits, including purchased tax credits, combined with lower earnings in 2025 as compared to 2024.

Net Income Attributable to Watsco, Inc.

Net income attributable to Watsco, Inc. in 2025 decreased $39.3 million, or 7%, compared to the same period in 2024, primarily due to lower revenues and gross profit and higher selling, general and administrative expenses, partially offset by lower income taxes and a decrease in the net income attributable to the non-controlling interest.

Refer to “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the year ended December 31, 2024 for a discussion of results of operations for the year ended December 31, 2024 compared to the year ended December 31, 2023.

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:

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 December 31, 2025, we had $433.3 million of cash and cash equivalents, of which $114.5 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 $300.0 million of short-term cash investments as of December 31, 2025 consisting of certificates of deposit with varying maturities through June 2026.

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, which is one of the base rates under our revolving credit agreement. 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 $2,236.8 million at December 31, 2025 from $2,096.1 million at December 31, 2024 primarily due to a decrease in accounts payable due to the timing of vendor payments and a decrease in accrued expenses and other current liabilities due to lower incentive pay accruals, partially offset by a decrease in accounts receivable in 2025 as compared to 2024.

The individual items contributing to cash flow changes for the years presented are detailed in the audited consolidated statements of cash flows included in this Annual Report on Form 10-K.

Operating Activities

Net cash provided by operating activities was lower primarily due to the timing of vendor payments, partially offset by a decrease in accounts receivable in 2025 as compared to 2024.

Investing Activities

Net cash used in investing activities decreased primarily due to proceeds from certificates of deposit that matured in 2025.

Financing Activities

Net cash used in financing activities increased primarily due to $281.8 million in net proceeds received in 2024 from the sale of Common stock under our 2021 ATM Program (as defined below), as well as timing differences in the distributions paid to the non-controlling interest, and increased dividends paid in 2025.

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), and we effected this reduction on October 1, 2025. Included in the revolving credit facility are a $125.0 million swing line loan sublimit, a $10.0 million letter of credit sublimit, a $75.0 million alternative currency borrowing sublimit, and a $10.0 million Mexican borrowing subfacility. The revolving credit agreement matures on March 16, 2028. Refer to Note 8 to our audited consolidated financial statements included in this Annual Report on Form 10-K for information regarding interest rates under our revolving credit agreement.

At December 31, 2025 and 2024, there was no outstanding balance 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 December 31, 2025.

At-the-Market Offering Program

On August 6, 2021, we entered into 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 $300.0 million (the “2021 ATM Program”).

During 2023, we issued and sold 45,000 shares of Common stock under the 2021 ATM Program for net proceeds of $15.2 million. During 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 a portion of the proceeds to repay outstanding debt under our revolving credit agreement and purchased short-term cash investments with the remainder. In aggregate, we issued and sold $298.5 million of Common stock under the 2021 ATM Program.

On May 3, 2024, we entered into an amended and restated sales agreement with Baird (the “2024 ATM Program”), which enables the further issuance and sale of Common stock for a maximum aggregate offering amount of up to $400.0 million. At December 31, 2025, $400.0 million 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).

Contractual Obligations

At December 31, 2025, operating lease liabilities for real property, vehicles, and equipment totaled $462.9 million and expire at various dates through 2035. Refer to Note 2 to our audited consolidated financial statements included in this Annual Report on Form 10-K for information on our operating lease liabilities and related maturities.

At December 31, 2025, we were obligated under various non-cancelable purchase orders with our key suppliers for goods aggregating approximately $18.1 million, of which approximately $17.7 million is with Carrier and its affiliates. Refer to Note 18 to our audited consolidated financial statements included in this Annual Report on Form 10-K, under the caption “Purchase Obligations”, for information on our contractual obligations at December 31, 2025.

The total amount of unrecognized tax benefits (net of the federal benefit received from state positions) relating to various tax positions we have taken, the timing of which is uncertain, was $6.7 million at December 31, 2025. Refer to Note 9 to our audited consolidated financial statements included in this Annual Report on Form 10-K for additional information on our unrecognized tax benefits.

Off-Balance Sheet Arrangements

Refer to Note 15 to our audited consolidated financial statements included in this Annual Report on Form 10-K, under the caption “Off-Balance Sheet Financial Instruments,” for a discussion of a standby letter of credit and performance bonds for which we were contingently liable at December 31, 2025.

Investment in Unconsolidated Entity

Carrier Enterprise I has a 38.4% ownership interest in RSI, an HVAC distributor operating from 36 locations in the Western U.S. Our proportionate share of the net income of RSI is included in other income in our consolidated statements of income.

Carrier Enterprise I is a party to a shareholders’ agreement with RSI and its shareholders (the “RSI Shareholders’ Agreement”), 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 a RSI 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 RSI 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 December 31, 2025, using the criteria set forth in the RSI Shareholders’ Agreement, the valuation of the RSI Shareholders’ RSI common stock was approximately $440.0 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 RSI 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 10 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 RSI 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, funds available for borrowing under our revolving credit agreement, or proceeds from the sale of Common stock under the 2024 ATM Program would be sufficient should the purchase of any additional ownership interests in RSI be made in cash pursuant to the agreement described in the preceding paragraph.

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.

Common Stock Dividends

We paid cash dividends of $11.70, $10.55, and $9.80 per share on common stock in 2025, 2024, and 2023, respectively. On January 2, 2026, our Board of Directors declared a regular quarterly cash dividend of $3.00 per share on common stock that was paid on January 30, 2026 to shareholders of record as of January 16, 2026. On February 10, 2026, our Board of Directors approved an increase to the annual cash dividend per share on common stock to $13.20 per share from $12.00 per share, effective with the quarterly dividend that will be paid in April 2026. 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 “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 pursuant to our automatically effective shelf registration statement on Form S-3 (File No. 333-282975). During 2025 and 2024, 47,765 and 27,561 shares of our common stock, respectively, were issued under the DRIP.

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 stock have been repurchased at a cost of $114.4 million since the inception of the program. At December 31, 2025, 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.

Quantitative and Qualitative Disclosures About Market Risk

We are exposed to market risks, including fluctuations in foreign currency exchange rates and interest rates. To manage certain of these exposures, we use derivative instruments, including forward and option contracts and swaps. We use derivative instruments as risk management tools and not for trading purposes.

Foreign Currency Exposure

We are exposed to cash flow and earnings fluctuations resulting from currency exchange rate variations. These exposures are transactional and translational in nature. The foreign currency exchange rates to which we are exposed are the Canadian dollar and Mexican peso. Revenues in these markets accounted for 5% and 2%, respectively, of our total revenues for 2025.

Our transactional exposure primarily relates to purchases by our Canadian operations in currencies other than their local currency. To mitigate the impact of currency exchange rate movements on these purchases, we consider entering into foreign currency forward contracts. By entering into these foreign currency forward contracts, we lock in exchange rates that would otherwise cause losses should the U.S. dollar strengthen, and gains should the U.S. dollar weaken, in each case against the Canadian dollar.

We have exposure related to the translation of financial statements of our Canadian operations into U.S. dollars, our functional currency. We do not currently hold any derivative contracts that hedge our foreign currency translational exposure. A 10% change in the Canadian dollar would have had an estimated $2.8 million impact to our financial position and results of operations for 2025.

Historically, fluctuations in these exchange rates have not materially impacted our results of operations. Our exposure to currency rate fluctuations could be material in the future if these fluctuations become significant or if our Canadian and Mexican markets grow and represent a larger percentage of our total revenues.

We had only one foreign exchange contract at December 31, 2025, the total notional value of which was $8.8 million, and such contract expired during January 2026. For the year ended December 31, 2025, foreign currency transaction gains and losses did not have a material impact on our results of operations. See Note 16 to our audited consolidated financial statements included in this Annual Report on Form 10-K for further information on our derivative instruments.

Interest Rate Exposure

Our revolving credit facility exposes us to interest rate risk because borrowings thereunder accrue interest at one or more variable interest rates. Our interest rate risk management objectives are to limit the impact of interest rate changes on earnings and cash flows and to lower overall borrowing costs. To achieve these objectives, we consider entering into interest rate swap agreements with financial institutions that have investment grade credit ratings, thereby minimizing the credit risk associated with these instruments. We do not currently hold any such swap agreements or any other derivative contracts that hedge our interest rate exposure, but we may enter into such instruments in the future.

At December 31, 2025, we had no exposure to changes in interest rates based on our variable indebtedness, as no amount was outstanding under our revolving credit agreement, however, we evaluated our exposure to interest rates assuming we are fully borrowed under our $600.0 million revolving credit agreement and determined that a 100 basis-point change in interest rates would result in an impact to income before income taxes of approximately $6.0 million. See Note 8 to our audited consolidated financial statements included in this Annual Report on Form 10-K for further information about our debt.

The primary objective of our investment activities is to preserve principal while secondarily maximizing yields without significantly increasing risk. To achieve this objective in the current uncertain global financial markets, all cash and cash equivalents were held in bank deposits and U.S. Treasury Bills as of December 31, 2025. As the interest rates on a material portion of our cash and cash equivalents are variable, a change in interest rates earned on our investment portfolio would impact interest income along with cash flows but would not materially impact the fair market value of the related underlying instruments. Based on the average cash balance held for fiscal 2025, a hypothetical 10% adverse change in our interest yield would not materially affect our operating results.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f). Our internal control system has been designed to provide reasonable assurance to our management and Board of Directors regarding the reliability of financial reporting and the preparation and fair presentation of our published consolidated financial statements.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective may not prevent or detect misstatements and can provide only reasonable assurance with respect to financial statement preparation and presentation. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Under the supervision and with the participation of our management, including our Chief Executive Officer, Executive Vice President, and Chief Financial Officer, we conducted an assessment of the effectiveness of our internal control over financial reporting as of December 31, 2025. The assessment was based on criteria established in the framework Internal Control — Integrated Framework (2013), issued by the Committee of Sponsoring Organizations (“COSO”) of the Treadway Commission. Based on this assessment under the COSO framework, our management concluded that our internal control over financial reporting was effective as of December 31, 2025. The effectiveness of our internal control over financial reporting as of December 31, 2025 has been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their report that is included herein.
