(July 15) High prices for lettuce means lower-than-expected earnings for Performance Food Group, Salinas, Calif., whose fresh-cut division operates as Fresh Express Retail and Fresh Express Foodservice. Performance, the nation’s fourth-largest broadliner, bought bagged-salad giant Fresh Express in 2001.

With iceberg peaking in the mid-$20s in June and continuing to sell for more than usual in July, Performance’s big contract clients have turned to the open market to find enough lettuce to meet demand. Demand has been driven in part by fast-food chains adding salads to their menus, according to Performance.

As a result, Performance expects second-quarter earnings of between 48 and 49 cents per share, down from the 50-52 cents per share it had anticipated.
