Albert H. Nahmad, Watsco’s President & Chief Executive Officer stated: “Watsco delivered another solid quarter of performance driven by sales growth, higher selling margins and improved operating efficiencies. We experienced healthy demand for residential products in the United States, which grew 13%, from strong unit growth and a better sales mix of high efficiency systems. We are off to a strong start and believe 2014 will be a record year for our company.”

Mr. Nahmad added, “We are also pleased to increase Watsco’s dividend to an annual rate of $2.40 per share beginning in July, well ahead of schedule. As evidenced by our long-term track record, we have great confidence in our business to produce both meaningful earnings growth and cash flow that exceeds net income. It is always our intention to share cash flow through increasing dividends. Having said that, we also want to retain the ability to invest in our network and additional opportunities that may come our way.”

It is important to note that the first quarter of each calendar year is the seasonal low point for sales and profits due to the magnitude of the replacement market for air conditioning, heating and refrigeration systems during the second and third quarters of each calendar year. Accordingly, the Company’s first quarter financial results are disproportionately affected by this seasonality and the overall general economic conditions.

About Watsco, Inc.

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 United States 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 568 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 $35 billion.
