Booz Allen CFO to retire

Booz Allen Hamilton said today that Kevin Cook, its chief financial officer, will retire, and Lloyd Howell, a longtime company executive who leads the contractor's civil commercial group, will succeed him, starting July 1.

Cook spent 23 years at Booz Allen, the company said.

Howell, 49, joined Booz Allen in 1988 as a consultant. He left in 1991 to earn his MBA, worked for Goldman Sachs and then returned to Booz Allen in 1995. He was named a partner in 2000 and has led the civil commercial group since 2013.
