Compass Minerals (NYSE: CMP) has published its first-quarter 2014 highway deicing sales volume and regional weather data on its website at www.compassminerals.com/marketdata. Compass Minerals’ highway deicing sales volume, which includes all highway maintenance products sold in the U.S., Canada and the U.K., as well as rock salt sold to the chemical industry, totaled approximately 4.7 million tons in the three months ended March 2014 compared with 4.4 million tons in the 2013 quarter and a 10-year average of 4.2 million tons. Eleven representative cities in the company’s primary North American highway deicing service area reported a total of 191 snow events during the first quarter of 2014 compared to 108 events in the same cities in the 2013 period according to the U.S. National Weather Service and AccuWeather, Inc. “The severe winter weather in North America fueled strong demand for all deicing products and generated our best first-quarter highway deicing sales volume since 2008,” said Compass Minerals CEO and president, Fran Malecha. “Rock salt inventories have been depleted throughout the North American regions we serve, so we expect highway deicing customers to request increased volumes in the upcoming contract bid season.” Conference Call to Discuss First-Quarter Financial Results The company will release its first-quarter 2014 financial results Monday, April 28, after the markets close and will discuss its results on a conference call Tuesday, April 29, at 9:00 a.m. ET.
