Rykoff expects its first-quarter net to drop.

Los Angeles-based Rykoff-Sexton Inc. said it expects earnings for its first quarter ended Aug. 2 to be below last year’s 41 cents a share, fully diluted, which assumes the exercise of warrants and stock options and the conversion of convertible bonds and preferred stock. Roger W. Coleman, president and chief executive of the food service company, said the decline reflects “greater than expected expenses” for integrating the four acquisitions that Rykoff made last year. The company earned 14 cents share in the previous fourth quarter.
