# McKesson **Source:** https://geo.sig.ai/brands/mckesson **Vertical:** Healthcare **Subcategory:** General **Tier:** Leader **Website:** mckesson.com **Last Updated:** 2026-04-14 ## Summary Largest US pharmaceutical distributor with $308.9B FY2024 revenue; thin-margin distribution triopoly with Cencora and Cardinal Health; US Oncology Network (1,700+ oncologists) is highest-margin segment. ## Company Overview McKesson Corporation is the largest pharmaceutical distributor in North America and a leading healthcare services company, founded in 1833 in New York City by John McKesson and Charles Olcott and now headquartered in Irving, Texas, trading on NYSE (MCK). The company reported approximately $308.9 billion in revenues for fiscal year 2024 (ending March 31, 2024) under CEO Brian Tyler, making it one of the highest-revenue companies in the United States—though the vast majority of revenues represent pass-through pharmaceutical product costs distributed to approximately 40,000 pharmacies, health systems, and medical providers across North America. McKesson operates through four segments: U.S. Pharmaceutical (the dominant distribution engine), Prescription Technology Solutions (pharmacy benefits technology including CoverMyMeds e-prior authorization), Medical-Surgical Solutions (physician office and extended care medical supply distribution), and International (primarily Canadian distribution through McKesson Canada). McKesson's pharmaceutical distribution business generates thin but highly predictable gross margins—typically 2-4% of revenues—on the enormous volume of branded and generic pharmaceuticals flowing from manufacturers to dispensing points. The company earns fee-for-service and price appreciation income in addition to distribution margin, particularly from branded pharmaceuticals where manufacturer price increases translate into inventory holding gains. The specialty pharmaceutical distribution segment—particularly oncology drugs distributed through McKesson's US Oncology Network (a physician services organization supporting over 1,700 oncologists)—commands higher margins than standard pharmaceutical distribution and provides access to high-cost specialty drugs that require specialized handling, reimbursement support, and clinical expertise. In 2025-2026, McKesson competes with Cencora (formerly AmerisourceBergen, ABC) and Cardinal Health (CAH) in the pharmaceutical distribution triopoly that collectively handles approximately 90% of U.S. pharmaceutical distribution. This oligopolistic structure provides pricing stability and durable margins absent competitive disruption. The three distributors' partial responsibility (as wholesalers) for the U.S. opioid epidemic resulted in a combined $21 billion settlement in 2022—McKesson's share approximately $8.2 billion payable over 18 years—creating a significant financial obligation that is being funded from ongoing free cash flow. McKesson's increasing focus on oncology—through US Oncology Network expansion, specialty drug distribution growth, and oncology software platforms—addresses the highest-growth and highest-margin segment within pharmaceutical distribution. ## Frequently Asked Questions ### What does McKesson Corporation do?
