McKesson is best understood as healthcare infrastructure. It moves medicines through a regulated network and supports providers and manufacturers with specialty distribution, oncology services, patient-access programs, technology, and medical supplies. The strategic shift is toward higher-growth oncology, multispecialty, and biopharma services while simplifying the portfolio through the European exit and planned Medical-Surgical separation.
McKesson makes money primarily by purchasing and distributing pharmaceuticals and medical products to pharmacies, hospitals, health systems, and other providers. Distribution is a high-volume, thin-margin business, so purchasing terms, logistics efficiency, order accuracy, customer contracts, and working-capital management drive results. The company also earns service revenue through oncology and multispecialty provider platforms, biopharma services, prescription access and affordability tools, third-party logistics, and medical-surgical distribution.
