Watsco Sets Records for Earnings Per Share, Net Income and Sales

During Fourth Quarter and Full-Year

Record Annual Cash Flow; Dividend Raised 16% to $5.80 Per Share

Adoption of Customer-Centric Technology Grows as Business Transformation Continues

MIAMI, FLORIDA – (GLOBENEWSWIRE), February 8, 2018 – Watsco, Inc. (NYSE: WSO) reported record operating results for the fourth quarter and year ended December 31, 2017.

The record operating results reflect continued investment in technologies designed to revolutionize Watsco’s customer-experience, making it easier to do business and helping customers grow their businesses more profitably. Most notably, the digitization of Watsco’s marketplace via e-commerce through iOS/Android-enabled apps and websites with the industry’s most in-depth database of product information made significant progress in 2017. Customer adoption increased enabling more contractors to interact with us 24 hours a day to find products, place orders and obtain technical support. Employees are also empowered with better data, processes and capabilities to serve their customers’ needs.

In addition to record operating performance, Watsco generated record operating cash flow of $302 million in 2017 on net income of $257 million. Watsco also raised $248 million during 2017 from the sale of shares of its common stock under its previously announced “at-the-market” (ATM) stock offering program, sharply reducing debt and positioning the Company to capitalize on long-term growth opportunities.

Watsco also announced today that its Board of Directors approved a 16% increase in its annual dividend to $5.80 per share for each outstanding share of its Common and Class B common stock. The increase will be reflected in the Company’s next regular dividend payment beginning in April 2018.

Fourth Quarter Results

Key performance metrics:

Sales trends:

Albert Nahmad, Watsco’s Chairman and Chief Executive Officer stated: “Watsco delivered another record quarter with a resumption of strong sales growth rates for residential and commercial HVAC systems from increasing unit demand and an improved mix of higher-efficiency systems. Results also reflect further investments in technology and 150 new customer-facing employees during the course of the year to drive sales growth and market share.”

Mr. Nahmad added: “We are pleased to reward shareholders by raising our annual dividend to $5.80 per share, reflecting our continued confidence to generate strong cash flow while investing in our business. We believe the sale of Watsco shares under the ATM program is both innovative and important as it positions the Company for almost any size investment over the long-term and is consistent with our conservative mindset about debt.”

It is important to note that the fourth quarter of each calendar year is highly seasonal due to the nature and timing of the replacement of HVAC systems, which is strongest in the second and third quarters. Accordingly, the Company’s fourth quarter financial results are disproportionately affected by seasonality.

Cash Flow & Dividends

Operating cash flow for the full year increased 9% to a record $302 million. Since 2000, Watsco’s cash flow was approximately $2.2 billion compared to net income of approximately $2.0 billion, surpassing the Company’s stated goal of generating cash flow in excess of net income.

Dividends paid in 2017 increased 29% to $164 million. On February 6, 2018, Watsco’s Board of Directors approved a 16% increase in its annual dividend to $5.80 per share on each outstanding share of its Common and Class B common stock. The increase will be reflected in the Company’s dividend payment on April 30, 2018.

Watsco has paid dividends for over 40 consecutive years with the philosophy of sharing increasing amounts of cash flow through higher dividends while maintaining a conservative financial position. Future increases in dividends, if any, will be considered in light of investment opportunities, cash flow, general economic conditions and the Company’s overall financial condition.

Watsco raised $248 million in 2017 from the sale of 1.5 million shares of Common stock under its ATM program. The cash proceeds were used to reduce long-term debt. As of December 31, 2017, the Company’s debt-to-total capitalization was 1%.

Technology Strategy

Watsco has launched a variety of technologies and process enhancements to transform how HVAC contractor customers are served in the marketplace. Watsco believes that speed, productivity and efficiency will be ever more critical as the digital era progresses and is investing to ensure an unparalleled customer-experience. Since 2012, Watsco’s technology team has grown from approximately 60 employees to 180 employees and the present annual run-rate for technology-related spending is approximately $23 million.

Watsco estimates that over 250,000 contractors and technicians visit or call one of its 560 locations each year to get information and buy products, resulting in over 7 million sale transactions. Innovations to enhance the customer-experience include:

A.J. Nahmad, Watsco’s President said, “We are proud of the progress we’ve made in regard to digitizing our business, but we’ve merely scratched the surface of what is possible in terms of value creation and realization. When our customers win, we win. To that end, our culture is one of continuous improvement, which will consistently enhance our customers’ businesses.”

Tax Cuts and Jobs Act of 2017

Income tax expense in 2017 reflects net tax benefits of $10 million from a reduction in deferred income tax liabilities partially offset by taxes related to undistributed earnings of our international operations and other changes. The impacts from tax reform in 2018 are being evaluated and we currently estimate our 2018 effective income tax rate (net of taxes attributable to non-controlling interest) will be in the range of 21% to 22%.
