Boehringer Ingelheim has been a contract manufacturer for Amgen, headquartered in Thousand Oaks, for more than ten years. The transaction has been approved by the board of directors of each company and is expected to close in March of this year. The Amgen Fremont facility is a 100,000-square-foot manufacturing facility with pilot plant and process development labs. It currently employs approximately 360 employees. Amgen obtained the Fremont facility through its 2006 acquisition of Abgenix. Amgen will continue to have a presence in the San Francisco Bay Area biotechnology community through its South San Francisco facility, one of the company’s key research centers.
