As one of the nation's largest pharmaceutical services providers, AmerisourceBergen works with manufacturers of branded pharmaceuticals, generic pharmaceuticals, biotech and specialty drugs, over-the-counter remedies, and health and beauty aids. The company provides service to independent retail pharmacies, national and regional chains, hospitals, clinics, pharmacy benefit managers, prescription mail order facilities, physician offices, and long-term care facilities.

AmerisourceBergen began operations in August 2001 following the merger of AmeriSource Health Corporation and Bergen Brunswig, two of the strongest players in the pharmaceutical services industry. The merger created AmerisourceBergen, making it the leader in pharmaceutical services and one of the largest pharmaceuticals distributors in the United States.

The company is headquartered in Valley Forge, PA, with a western management center in Orange, CA. AmerisourceBergen has 26 pharmaceutical distribution centers and three specialty distribution centers strategically located throughout the United States; and nine distribution centers in Canada. The company handles about 20% of all of the pharmaceuticals sold and distributed throughout the U.S.

In fiscal 2010, the company reported record revenues of $77.9 billion and net income of $636.7 million.


AmeriSource Health Corporation began when Cleveland millionaire Tinkham Veale entered the drug wholesaling business with his company Alco Standard in 1977. Beginning with the purchase of The Drug House, Alco Standard embarked upon a series of acquisitions to build its wholesaling presence. By the early 1980s, Alco Standard, under the name Alco Health Services, was the third largest wholesale drug distributor in the United States.

In 1989, Alco Standard spun off Alco Health Services in a leveraged buyout. Through strategic acquisitions and expanded product lines, Alco Health boosted its sales and went public as AmeriSource Health Corporation in 1995. AmeriSource continued to increase its asset base by purchasing other companies to move into related areas such as inventory management technology and drugstore pharmaceutical supplies.

By 2000, AmeriSource Health Corporation, with 22 distribution centers and nearly $14 billion in operating revenue, was the fourth largest distributor of pharmaceuticals and related healthcare products and solutions.

Bergen Brunswig had a similar history of mergers and acquisitions as its primary method of growth. Lucien Napoleon Brunswig founded Brunswig Drug Company in 1907, after relocating and renaming a New Orleans-based wholesale drug company to Los Angeles in 1903. Bergen Brunswig was formed in 1969 when Brunswig Drug Company merged with Bergen Drug, a firm founded by Emil Martini in 1947.

In 1989, the company, which had grown through acquisitions from sales of $200,000 per sales person to $1.6 million per sales person since 1975, went public. Bergen Brunswig continued to increase its holdings by acquiring businesses in the healthcare distribution sector, such as pharmacy giant PharMerica.

By 2000, Bergen Brunswig Corporation was the third largest distributor of pharmaceuticals and related healthcare products and solutions with more than 30 locations in the United States and Puerto Rico.
