AmerisourceBergen Acquires Premier Source

AmerisourceBergen Corporation (NYSE: ABC) today announced that it has completed the acquisition of Premier Source, a privately held company that provides consulting and reimbursement services to medical device, pharmaceutical, molecular diagnostic, and biotechnology manufacturers, as well as other health services companies. The financial terms of the transaction were not disclosed.

"We are very excited about Premier Source joining AmerisourceBergen," said Peyton Howell, President of AmerisourceBergen Consulting Services (ABCS) and Senior Vice President, Business Development of AmerisourceBergen. "Premier Source has been focused on the diagnostics market, and their business complements the work we do in both our consulting businesses under Lash Group and Xcenda.”

"We are extremely pleased that our company will continue to thrive as part of AmerisourceBergen," added Sinead Foley, President of Premier Source. "The integration will help strengthen our focus on emerging diagnostic, biotech and device manufacturers; and in turn, differentiate our group.”

"With our broad range of market access programs,” Howell continued, "The acquisition of Premier Source provides ABCS with strategically expanded capabilities to help our business partners positively impact patients’ lives."

Premier Source, headquartered in San Mateo, CA, with an office in Portland, OR, will be a business unit within ABCS, and Foley will continue with the title of President of Premier Source, reporting into Lash Group’s President Tracy Foster. Founded in 2004, Premier Source offers expertise in the areas of managed care and reimbursement, particularly for life sciences companies developing novel therapies and molecular diagnostics, helping those clients eliminate barriers to coverage for their products.
