Company Overview

Watsco, Inc. was incorporated in Florida in 1956, and, together with its subsidiaries (collectively, “Watsco,” 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, 2021, we operated from 671 locations in 42 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.

COVID-19
Pandemic

The
COVID-19
pandemic continues to have widespread, rapidly-evolving and unpredictable impacts on financial markets and business practices. As conditions fluctuate, governments and organizations have responded by adjusting their restrictions and guidelines accordingly. Although we have learned to navigate
COVID-19
while maintaining our operations in all material respects, our focus remains on promoting employee health and safety, serving our customers and ensuring business continuity.

In response to the pandemic, we implemented plans intended to preserve adequate liquidity and ensure that our business continued to operate during this uncertain time. In addition, we took actions to reduce costs, including reductions in compensation, rent abatement, changes to vendor terms and other austerity measures to curtail discretionary spending in light of the circumstances in 2020. As restrictions have eased and normal economic conditions have largely resumed, our various austerity measures to curtail discretionary spending have eased.

As economic activity has been recovering and the effects of the pandemic lessened in 2021, the impact of the pandemic on our business has been more reflective of greater economic and marketplace dynamics rather than pandemic-related issues, such as location closures, mandated restrictions and employee illness. Manufacturers experienced some level of supply chain disruptions caused by constrained component availability, labor shortages, transportation delays, and other logistical challenges, all of which impacted typical lead times and overall availability of HVAC/R products. These supply chain disruptions impacted our ability to fulfill contractor demand at various points during 2021. Despite these disruptions, we experienced growth in sales of residential units during the year. As of the date of this filing, product availability has improved in recent months and more typical inventory levels are being reestablished to meet the continued strong
end-market
demand.

Notwithstanding the recent resurgence of economic activity, in light of variant strains of the virus and the continued rate of viral infections that exists as of the date of this filing, there remains uncertainty concerning the magnitude of the impact and duration of the
COVID-19
pandemic. The full impact of the
COVID-19
pandemic on our financial condition and results of operations will continue to depend on future developments, such as the ultimate duration and scope of the pandemic, its impact on our employees, customers and suppliers, potential subsequent waves of
COVID-19
infection or potential new variants, the effectiveness and adoption of
COVID-19
vaccines and therapeutics, the broader implications of the macro-economic recovery on our business, and the extent to which normal economic and operating conditions are impacted, and whether the pandemic exacerbates the risks disclosed in Item 1A “Risk Factors” of this Annual Report on Form
10-K
for the year ended December 31, 2021. We intend to continue to actively monitor the situation and may take further actions that alter our business operations as may be required by federal, state or local authorities or that we determine are in the best interests of our employees, customers, suppliers and shareholders.

Climate Change and Reductions in CO
2
e Emissions

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

Table of Contents

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

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 periodically increase the required minimum SEER, thus providing a catalyst for greater sales of higher-efficiency systems.

We offer a broad variety of systems that operate beyond the minimum SEER standards, including systems that operate at more than 20 SEER. Our sales of higher-efficiency residential HVAC systems grew 26% organically in 2021, outpacing the overall growth rate of 17% for residential HVAC equipment in the United States. Based on estimates validated by independent sources, we averted an estimated 10.1 million metric tons of CO2e emissions during 2020 and 2021 through the sale of replacement residential HVAC systems at higher-efficiency standards.

Joint Ventures with Carrier Global Corporation

In 2009, we formed a joint venture with Carrier, which we refer to as Carrier Enterprise I, in which Carrier contributed company-owned locations in the Sun Belt states and Puerto Rico, and its export division in Miami, Florida, and we contributed certain locations that distributed Carrier products. We have an 80% controlling interest in Carrier Enterprise I, and Carrier has a 20%
non-controlling
interest. The export division, Carrier InterAmerica Corporation, redomesticated from the U.S. Virgin Islands to Delaware effective December 31, 2019, following which Carrier InterAmerica Corporation became a separate operating entity in which we have an 80% controlling interest and Carrier has a 20%
non-controlling
interest. On August 1, 2019, Carrier Enterprise I acquired substantially all of the HVAC assets and assumed certain of the liabilities of Peirce-Phelps, Inc. (“PPI”), an HVAC distributor operating from 19 locations in Pennsylvania, New Jersey, and Delaware.

In 2011, we formed a second joint venture with Carrier, which we refer to as Carrier Enterprise II, in which Carrier contributed company-owned locations in the Northeast U.S., and we contributed certain locations operating as Homans Associates LLC (“Homans”), a Watsco subsidiary, in the Northeast U.S. Subsequently, Carrier Enterprise II purchased Carrier’s distribution operations in Mexico. We have an 80% controlling interest in Carrier Enterprise II, and Carrier has a 20% non-controlling interest. Effective May 31, 2019, we repurchased the 20% ownership interest in Homans from Carrier Enterprise II, following which we own 100% of Homans. Homans previously operated as a division of Carrier Enterprise II and subsequent to the purchase operates as a wholly owned subsidiary of the Company.

In 2012, we formed a third joint venture with Carrier, which we refer to as Carrier Enterprise III. Carrier contributed 35 of its company-owned locations in Canada to Carrier Enterprise III. We have a 60% controlling interest in Carrier Enterprise III, and Carrier has a 40%
non-controlling
interest.

On April 9, 2021, we acquired certain assets and assumed certain liabilities comprising the HVAC distribution business of Temperature Equipment Corporation, an HVAC distributor operating from 32 locations in Illinois, Indiana, Kansas, Michigan, Minnesota, Missouri and Wisconsin. We formed a new, stand-alone joint venture with Carrier, TEC Distribution LLC (“TEC”), that operates this business. We have an 80% controlling interest in TEC, and Carrier has a 20%
non-controlling
interest.

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.

Table of Contents

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 them.

Allowance for Doubtful Accounts

An allowance for doubtful accounts is maintained for estimated losses resulting from the inability of customers to make 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 $11.3 million and $7.1 million at December 31, 2021 and 2020, respectively, an increase of $4.2 million, which is primarily due to an account delinquent in their payments due to us as of December 31, 2021. Accounts receivable balances greater than 90 days past due as a percent of accounts receivable at December 31, 2021 decreased to 0.9% from 1.4% at December 31, 2020, primarily attributable to an improvement in the underlying quality of our accounts receivable portfolio at December 31, 2021.

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.

Inventory Valuation Reserves

Inventory valuation reserves 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 also maintained and reflects the results of cycle count programs and physical inventories. When preparing these estimates, management considers historical results, 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, 2022, 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 incorporates 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

Table of Contents

assets were $1,124.5 million and $999.9 million at December 31, 2021 and 2020, respectively, an increase of $124.6 million, primarily reflecting newly acquired businesses. Although no 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 $7.3 million and $5.4 million at December 31, 2021 and 2020, respectively, were established related to such insurance programs.

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 $5.1 million and $0.7 million was recorded at December 31, 2021 and 2020, 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 IRC 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

There have been no new accounting standards made effective during 2021 that have significance, or potential significance, to our consolidated financial statements.

Results of Operations

The following table summarizes information derived from our audited consolidated statements of income, expressed as a percentage of revenues, for the years ended December 31, 2021, 2020 and 2019.

Table of Contents

Note: Due to rounding, percentages may not add up to 100.

The following narratives reflect our acquisitions of Makdad Industrial Supply Co., Inc. (“MIS”) in August 2021, Acme Refrigeration of Baton Rouge LLC (“ACME”) in May 2021, and Temperature Equipment Corporation in April 2021.

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, 2021 and 2020, four and two locations, respectively, that we had 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 2021 and 2020:

2021 Compared to 2020

Revenues

Revenues for 2021 increased $1,225.3 million, or 24%, to $6,280.2 million, including $326.5 million attributable to new locations acquired and $19.1 million from other locations opened during the preceding 12 months, offset by $8.0 million from locations closed. Sales of HVAC equipment (69% of sales) increased 23%, sales of other HVAC products (28% of sales) increased 22% and sales of commercial refrigeration products (3% of sales) increased 29%. On a same-store basis, revenues increased $887.7 million, or 18%, as compared to 2020, reflecting an 18% increase in sales of HVAC equipment (69% of sales), which included an 18% increase in residential HVAC equipment (17% increase in U.S. markets and a 26% increase in international markets) and a 17% increase in sales of commercial HVAC equipment (16% increase in U.S. markets and a 20% increase in international markets), a 17% increase in sales of other HVAC products (27% of sales), and a 29% increase in sales of commercial refrigeration products (4% of sales). For HVAC equipment, the increase in revenues was primarily due to strong demand for residential HVAC equipment, the realization of price increases, and a greater mix of high-efficiency air conditioning and heating systems, which sell at higher unit prices. During 2021, the unit volume for residential unitary air conditioning equipment increased 8% and the average selling price increased 9%.

Table of Contents

Gross Profit

Gross profit for 2021 increased $444.7 million, or 36%, to $1,667.5 million, primarily as a result of increased revenues. Gross profit margin improved 240 basis-points to 26.6% in 2021 versus 24.2% in 2020, primarily due to the benefits of pricing actions implemented using technologies to optimize pricing and margins to pass on price increases from our suppliers to our customers and an improved sales mix of higher-efficiency HVAC systems.

Selling, General and Administrative Expenses

Selling, general and administrative expenses for 2021 increased $225.3 million, or 27%, to $1,058.3 million, primarily due to increased revenues and newly acquired locations. Selling, general and administrative expenses as a percentage of revenues for 2021 increased to 16.9% versus 16.5% in 2020. On a same-store basis, selling, general and administrative expenses increased 19% as compared to 2020 and as a percentage of sales increased to 16.6% versus 16.5% in 2020. The increase was primarily related to increased higher variable selling costs driven by the increase in revenues, investments in employee headcount and performance-based compensation costs (commissions and bonuses throughout the Company), increased logistics costs in response to strong demand and continuing supply chain disruptions, and increased rent expense associated with new locations opened. Selling, general and administrative expenses in 2021 also reflect a $7.6 million increase in spending for ongoing technology initiatives.

Other Income

Other income of $19.3 million and $11.3 million for 2021 and 2020, respectively, represented our share of the net income of Russell Sigler, Inc. (“RSI”), in which we have a 38.1% equity interest.

Operating Income

Operating income for 2021 increased $227.5 million, or 57%, to $628.5 million. Operating margin improved 210 basis-points to 10.0% in 2021 from 7.9% at 2020. On a same-store basis, operating margin was 10.1% in 2021 as compared to 7.9% in 2020.

Interest Expense, Net

Interest expense, net for 2021 decreased $0.2 million, or 20%, to $1.0 million, primarily as a result of a decrease in average outstanding borrowings for the 2021 period, as compared to the same period in 2020.

Income Taxes

Income taxes increased 68% to $128.8 million and represent a composite of the income taxes attributable to our wholly owned operations and income taxes attributable to the Carrier joint ventures, 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 effective income tax rates attributable to us were 23.4% and 22.0% for 2021 and 2020, respectively. The increase was primarily due to the addition of a valuation allowance on the deferred tax asset related to share-based compensation, higher state income taxes, and proportionately higher income in 2021 as compared to tax credits and share-based compensation deductions in 2020.

Net Income Attributable to Watsco, Inc.

Net income attributable to Watsco in 2021 increased $149.4 million, or 55%, to $418.9 million. The increase was primarily driven by higher revenues and expanded profit margins, partially offset by higher selling, general and administrative expenses, income taxes, and an increase in the net income attributable to the
non-controlling
interest.

Liquidity and Capital Resources

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

7

Table of Contents

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.

As of December 31, 2021, we had $118.3 million of cash and cash equivalents, of which $103.6 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 believe that our operating cash flows, cash on hand, funds available for borrowing under our revolving credit agreement, and funds available from sales of our Common stock under our

at-the-market

offering 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.

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 LIBOR, which is one of the base rates under our revolving credit agreement. On March 5, 2021, the United Kingdom Financial Conduct Authority, which regulates LIBOR, confirmed that LIBOR will either cease to be provided by any administrator or will no longer be representative after June 30, 2023 for USD LIBOR reference rates. Our revolving credit agreement provides that it may be amended to replace LIBOR with an alternate benchmark rate. The impact of such an amendment cannot be entirely predicted but could result in an increase in the cost of our debt. Additionally, disruptions in the credit and capital markets could also result in increased borrowing costs and/or reduced borrowing capacity under our revolving credit agreement.

Working Capital

Working capital increased to $1,234.7 million at December 31, 2021, which includes 56 locations added by acquisitions in 2021 that in aggregate added $91.1 million of working capital. Excluding these acquired locations, working capital increased 15% to $1,143.6 million at December 31, 2021 from $997.3 million at December 31, 2020, primarily due to higher accounts receivable consistent with overall increased sales and higher levels of inventory in support of stronger business conditions.

Cash Flows

The following table summarizes our cash flow activity for 2021 and 2020 (in millions):

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

The decrease in net cash provided by operating activities was primarily due to higher levels of inventory in support of strong business conditions and higher accounts receivable driven by increased sales, partially offset by timing of vendor payments in 2021 as compared to 2020.

Investing Activities

Net cash used in investing activities was higher primarily due to cash consideration paid for acquisitions.

8

Table of Contents

Financing Activities

The decrease in net cash used in financing activities was primarily attributable to net borrowings under our revolving credit agreement in 2021 versus net repayments in 2020 and $21.0 million in proceeds from the
non-controlling
interest for its contribution to the acquisition of Temperature Equipment Corporation in 2021, partially offset by an increase in dividends paid in 2021.

Revolving Credit Agreement

We maintain an unsecured, $560.0 million syndicated multicurrency revolving credit agreement, which we use to fund 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 credit facility has a seasonal component from October 1 to March 31, during which the borrowing capacity may be reduced to $460.0 million at our discretion (which effectively reduces fees payable in respect of the unused portion of the commitment), and we effected this reduction in 2021. Included in the credit facility are a $100.0 million swingline subfacility, a $10.0 million letter of credit subfacility, a $75.0 million alternative currency borrowing sublimit and an $8.0 million Mexican borrowing sublimit. The credit agreement matures on December 5, 2023.

Borrowings under the credit facility bear interest at either LIBOR-based rates plus a spread, which ranges from 87.5 to 150.0 basis-points (LIBOR plus 87.5 basis-points at December 31, 2021), depending on our ratio of total debt to EBITDA, or on rates based on the highest of the Federal Funds Effective Rate plus 0.5%, the Prime Rate or the Eurocurrency Rate plus 1.0%, in each case plus a spread which ranges from 0 to 50.0 basis-points (0 basis-points at December 31, 2021), depending on our ratio of total debt to EBITDA. We pay a variable commitment fee on the unused portion of the commitment under the revolving credit agreement, ranging from 7.5 to 20.0 basis-points (7.5 basis-points at December 31, 2021).

At December 31, 2021 $89.0 million was outstanding under the revolving credit agreement. At December 31, 2020 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, 2021.

At-the-Market

Offering Program

On August 6, 2021, we entered into a sales agreement with Robert W. Baird & Co. Inc. (“Baird”), which enables 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 (the “ATM Program”). The offer and sale of our Common stock pursuant to the ATM Program has been registered under the Securities Act pursuant to our automatically effective shelf registration statement on Form
S-3
(File

Contractual Obligations

At December 31, 2021, operating lease liabilities for real property, vehicles and equipment totaled $269.0 million and expire at various dates through 2031. 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.

On October 15, 2022, 975,622 shares of Class B restricted stock held by our Chief Executive Officer (“CEO”) will vest. The CEO may elect to satisfy the tax withholding obligations in connection with the vesting of restricted stock either by the Company’s withholding of shares otherwise deliverable to the CEO, or in cash, or any combination of the two. If the CEO elects to withhold shares, we would satisfy the withholding tax obligations in cash. Based on the closing price of Watsco’s Class B common stock and withholding tax rates in effect at December 31, 2021, the estimated withholding tax obligation would have been approximately $118.0 million had the shares vested on December 31, 2021.

Commercial obligations outstanding at December 31, 2021 under our revolving credit agreement consisted of borrowings totaling $89.0 million with revolving maturities of nine days.

At December 31, 2021, we were obligated under various
non-cancelable
purchase orders with our key suppliers for goods aggregating approximately $45.0 million, of which approximately $31.0 million is with Carrier and its affiliates. These purchase obligations represent commitments under purchase orders for goods in the ordinary course of business that are enforceable and legally binding with defined terms as to price, quantity, and delivery.

Investment in Unconsolidated Entity

Carrier Enterprise I has a 38.1% ownership interest in RSI, an HVAC distributor operating from 34 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 (the “Shareholders’ Agreement”) with RSI and its shareholders. Pursuant to the Shareholders’ Agreement, RSI’s 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 either book value or a multiple of EBIT, the latter of which Carrier Enterprise I used to calculate the price paid for its investment in RSI. RSI’s 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 RSI’s shareholders the remaining outstanding shares of RSI common stock. At December 31, 2021, the estimated purchase amount we would be contingently liable for was approximately $315.0 million. We believe that our operating cash flows, cash on hand, and funds available for borrowing under our revolving credit agreement would be sufficient to purchase any additional ownership interests in RSI.

Acquisitions

On August 20, 2021, one of our wholly owned subsidiaries acquired MIS, a distributor of air conditioning and heating products operating from six locations in Pennsylvania. Consideration for the purchase price consisted of $3.1 million in cash and the issuance of 3,627 shares of Common stock having a fair value of $1.0 million, net of cash acquired of $0.2 million.

On May 7, 2021, we acquired certain assets and assumed certain liabilities of ACME, a distributor of air conditioning, heating, and refrigeration products, operating from 18 locations in Louisiana and Mississippi, for $22.9 million less certain average revolving indebtedness. Consideration for the net purchase price consisted of $18.1 million in cash, 8,492 shares of Common stock having a fair value of $2.6 million, and $3.1 million repayment of indebtedness, net of cash acquired of $1.3 million.

On April 9, 2021, we acquired certain assets and assumed certain liabilities comprising the HVAC distribution business of Temperature Equipment Corporation, an HVAC distributor operating from 32 locations in Illinois, Indiana, Kansas, Michigan, Minnesota, Missouri and Wisconsin. We formed a new, stand-alone joint venture with Carrier, TEC, that operates this business. We have an 80% controlling interest in TEC, and Carrier has a 20%
non-controlling
interest. Consideration for the purchase was paid in cash, consisting of $105.2 million paid to Temperature Equipment Corporation (Carrier contributed $21.0 million and we contributed $84.2 million) and $1.5 million for repayment of indebtedness.

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

Common Stock Dividends

We paid cash dividends of $7.625, $6.925 and $6.40 per share of Common stock and Class B common stock in 2021, 2020, and 2019, respectively. On January 3, 2022, our Board of Directors declared a regular quarterly cash dividend of $1.95 per share of both Common and Class B common stock that was paid on January 31, 2022 to shareholders of record as of January 14, 2022. On February 8, 2022, our Board of Directors approved an increase to the annual cash dividend per share of Common and Class B common stock to $8.80 per share from $7.80 per share, effective with the quarterly dividend that will be paid in April 2022. 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, and future prospects.
