AmerisourceBergen (NYSE: ABC) sells drugs to health care providers such as hospitals, pharmacies and clinics. The company acts as an intermediary, or middleman, between drug manufacturers and providers and ranks as the third-largest U.S. pharmaceutical distributor in the $250B pharmaceutical distribution industry, behind McKesson (MCK) and Cardinal Health (CAH). Drug distributors provide the specialized delivery services to end consumers. They ensure that the drugs are stored and transported under the prescribed conditions (adequate refrigeration, pressure, etc.) and delivered to secure locations. Whereas ABC's competitors have expanded into medical product manufacturing, healthcare information technology, and other services, ABC remains focused on pharmaceutical distribution.
