Watsco Sets New Records for Earnings Per Share,

Operating Margins and Sales During 2014

MIAMI, FLORIDA – (BUSINESS WIRE), February 12, 2015 – Watsco, Inc. (NYSE: WSO) today reported record results for the fourth quarter and for the year ended December 31, 2014.

Fourth Quarter Results

Key performance metrics:

Sales trends:

Albert Nahmad, Watsco’s President & Chief Executive Officer stated: “Watsco delivered another solid quarter of earnings growth from higher sales, improved selling margins and effective leveraging of operating costs, resulting in record operating margins. We saw continued strength in sales of residential HVAC systems from strong unit demand and an improved mix of higher-efficiency systems. Overall, our results represent a great finish to another excellent year.”

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 market for air conditioning systems, which is strongest in the second and third quarters. Accordingly, the Company’s fourth quarter financial results are disproportionately affected by this seasonality.

About Watsco

Watsco improves indoor living and working environments with air conditioning and heating solutions that provide comfort regardless of the outdoor climate. Our solutions also promote healthier indoor spaces by removing pollutants from the indoor air that can lead to asthma, allergies and reductions in productivity. Furthermore, since heating and cooling accounts for approximately half of the energy consumed in a typical U.S. home, we offer consumers the greatest opportunity to save money on energy by replacing existing air conditioning and heating systems with more energy efficient and environmentally friendly solutions.

There are approximately 89 million central air conditioning and heating systems installed in the United States that have been in service for more than 10 years. Older systems often operate below today’s government mandated energy efficiency and environmental standards. Watsco has an opportunity to accelerate the replacement of these systems at a scale greater than our competitors as the movement toward reducing energy consumption and its environmental impact continues. We operate from more than 570 locations in the United States, Canada, Mexico and Puerto Rico, with additional market coverage on an export basis to Latin America and the Caribbean. As the industry leader, significant growth potential remains given that the estimated marketplace in the Americas for HVAC/R products is approximately $35 billion.
