US Cellular names new CEO; 1Q net down 43 pct

U.S. Cellular Corp. says McDonald's Corp. marketing executive Mary N. Dillon will lead the wireless provider when CEO John E. Rooney retires June 1.

The appointment was disclosed Monday as U.S. Cellular reported a 43 percent drop in first-quarter earnings, with its average revenue per customer down and expenses rising.

The 48-year-old Dillon serves as global chief marketing officer at McDonald's, where she has worked since 2005. Prior to that, she was president of PepsiCo Inc.'s Quaker Foods division.

Telephone and Data Systems Inc., which owns an 82 percent stake in U.S. Cellular, had said in February that Rooney would retire as CEO of U.S. Cellular this year and hired an executive search firm to replace him. Rooney has been president and CEO since since 2000.
