Compass Minerals Announces Conference Call to Discuss First-Quarter Financial Results

April 14, 2009
Results Will Reflect Continued Pricing Strength Combined With Lower Sales Volumes

OVERLAND PARK, Kan.--(BUSINESS WIRE)--Apr. 14, 2009-- Compass Minerals (NYSE:CMP) will release its first-quarter 2009 financial results after the close of the markets on Monday, April 27, 2009, and will discuss its results on a conference call on Tuesday, April 28, at 10:00 a.m. ET.

“Compass Minerals’ salt segment continued to demonstrate significant resistance to the difficult economy during the first quarter. Salt segment pricing remained robust, though mild weather in February and March caused deicing salt sales volumes to be lower than we would normally expect for a March quarter,” said Angelo Brisimitzakis, Compass Minerals president and CEO. “In our specialty fertilizer segment, trends that began in the fourth quarter of 2008 continued during the first quarter of 2009. The average selling price of sulfate of potash remained strong while sales volumes were sharply lower, consistent with broader potash industry trends.”
