Stocks in Motion: Martek, Mace

Updated from 12:43 p.m. EDT

Shares of Martek Biosciences(MATK Quote) fell as much as 10% Thursday after the company missed second-quarter earnings estimates and warned that third-quarter revenue would fall short of estimates.

The Columbia, Md.-based food-additives company earned 11 cents a share on sales of $41.9 million during the second quarter. Analysts polled by Thomson First Call were looking for the company to earn 14 cents a share on sales of $39.4 million. Looking ahead, Martek said a fire that occurred at a trading partner's facilities in May will hamper the company's ability to meet revenue forecasts. The production loss will cause a reduction of about $7 million to $9 million in revenue for Martek during the third quarter. The facility is scheduled to restart production today, but reduced volume is expected, which will result in lower-than-anticipated deliveries of arachidonic acid in the fourth quarter. Martek sells the acid to its infant formula licensees.
