Drug distributor AmerisourceBergen Corp. on Friday promoted Steven Collis, the president of its largest subsidiary, to president and chief operating officer of the company.

Collis, 49, has been president of the AmerisourceBergen Drug Corp. business since August 2009. Before that he was president of the company's specialty group. The company said R. David Yost is still its CEO, but has given up the title of president. The changes are effective immediately.

AmerisourceBergen has not had a chief operating officer since September 2007, when President and COO Kurt Hilzinger resigned to join a private equity firm.
