Behind the drugs you buy is an entire industry built on supplying, pricing, and subsidizing those meds, which is where AmerisourceBergen lives. The megapharma company was formed in 2001, when Amerisource Health Corporation merged with Bergen Brunswig Corporation. Today, the resulting hybrid handles 20% of all of the pharmaceuticals sold and distributed throughout the United States, and employs 13,400 people full-time.
The pharma industry has undergone consolidation, with companies forming even larger units to prepare for health care reform, when the government will become an even more powerful drug-purchasing competitor. So AmerisourceBergen signed a three-year contract with Express Scripts, which had just bought Medco Health. Both Express Scripts and Medco are pharma suppliers and consultants. In 2013, AmeriSourceBergen penned a deal with Walgreen (Fortune 500) and Alliance Boots. The deal could give the triad the purchasing power to buy more generics than any other purchaser in the industry. ,
Wal-Mart retook the top spot, Berkshire Hathaway made the top five, and Apple grew enormously.
