Extremely Mild Winter Weather Leads to Reduced Goderich Production and Lower 2015 Earnings Outlook

Extremely mild weather to-date throughout Compass Minerals’ (NYSE-CMP) primary North American service area has reduced demand for the company’s deicing products in the fourth quarter. As a result, the company has announced reduced production at its Goderich mine along with a staff reduction of approximately 90 employees.

Lower deicing demand, as well as continued weakness in the plant nutrition business, is expected to drive Compass Minerals’ full-year earnings per share below the low end of the prior guidance range of $5.20 to $5.50 per share.

The company expects to provide its customary fourth-quarter report on snow event data as well as salt segment sales volume results on Jan. 7, 2016.
