Amgen Inc., the world's largest biotech drugmaker, says Chairman and CEO Kevin Sharer will retire in 2012 and will be replaced by President and Chief Operating Officer Robert Bradway.
Amgen says Bradway will become its CEO on May 23 and he will replace Sharer as chairman at the end of 2012. Sharer, 63, has been Amgen's CEO since May 2000 and was elected chairman in January 2001. He was the president of the company from 1992 to 2010.
Amgen hired Bradway as vice president of operations in 2006. He was named CFO the following year and became chief operating officer and replaced Sharer as president in 2010.
The California-based company also said Roger Perlmutter will retire as head of research and development Feb. 13.
