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).
Cambridge MA neuroscience biopharma (NASDAQ: BIIB) at $9.7B 2024 revenue; LEQEMBI $87M Q4 (Alzheimer's first-in-class amyloid therapy), SKYCLARYS $102M Q4 (Friedreich's ataxia), MS franchise declining vs. Eli Lilly donanemab.
Biogen Inc. is a Cambridge, Massachusetts-based neuroscience biopharmaceutical company — publicly traded on NASDAQ (NASDAQ: BIIB) as an S&P 500 Health Care component — researching, developing, and commercializing therapies for neurological, neurodegenerative, and neurodevelopmental diseases including Alzheimer's disease, multiple sclerosis, spinal muscular atrophy, and rare neurological conditions through approximately 7,400 employees worldwide. In fiscal year 2024, Biogen reported total revenue of $9.7 billion (-2% year-over-year) and GAAP diluted EPS of $11.18 (+40%), reflecting significant cost-cutting that improved profitability despite modest revenue decline. Revenue decline was driven by continued erosion in the core multiple sclerosis franchise (TECFIDERA, AVONEX, TYSABRI facing generic and biosimilar competition) while new product revenue grew: LEQEMBI (lecanemab, Alzheimer's disease, partnered with Eisai) generated approximately $87 million in Q4 2024 global sales — reflecting the slow but building commercial trajectory of the first drug to slow Alzheimer's cognitive decline — and SKYCLARYS (omaveloxolone, Friedreich's ataxia) generated $102 million in Q4, nearly double the year-earlier period. CEO Christopher Viehbacher, who joined in 2022 from Genentech's parent Roche, has led a strategic restructuring that includes cost reduction, pipeline refocus on high-probability neurology programs, and the LEQEMBI commercial execution through a partnership model with Eisai.
