McKesson is North America's largest pharmaceutical distributor, operating a low-margin, high-volume logistics network that moves ~30% of all prescription drugs in the U.S. and Canada. The company generates value through scale advantages in procurement, distribution density across 13,000+ pharmacies, and specialty pharmacy services for oncology and rare disease medications. Stock performance is driven by prescription volume growth, generic drug sourcing margins, and the company's ability to extract operational efficiency from its massive distribution infrastructure.
HealthcarePharmaceutical Distribution & Specialty Healthcare Servicesmoderate - Distribution network has high fixed costs (warehouses, transportation fleet, IT infrastructure), but variable costs dominate at 96.5% of revenue (product acquisition). Incremental volume drops significant profit to bottom line once infrastructure is in place, evidenced by operating margin expansion from 0.9% to 1.2% as revenue grew 16.2%. However, pricing pressure from PBM consolidation (CVS/Aetna, Cigna/Express Scripts) limits ability to pass through cost inflation.
