McKesson

McKesson, founded in 1833, is a Fortune 10 healthcare services company with nearly two centuries of operational history. With 45,000 employees across North America, it operates as one of the continent's most significant healthcare infrastructure providers, distributing approximately one-third of all pharmaceuticals used in the region.

The company's operations span four primary business segments: North American Pharmaceutical Distribution, Oncology and Multispecialty Solutions, Medical-Surgical Solutions, and Prescription Technology Solutions. Its technical domains include distribution logistics, oncology research and care management, healthcare technology, and data analytics - disciplines that underpin its partnerships with payors, hospitals, physician offices, pharmacies, and pharmaceutical companies across the spectrum of care.

McKesson's institutional longevity is notable: the company has demonstrated sustained relevance through major public health crises, from the 1918 flu pandemic to the distribution of COVID-19 vaccines. This track record reflects an organization that has repeatedly adapted its capabilities to meet the evolving demands of healthcare delivery at continental scale.
