Who are the top 10 healthcare companies?
Based on FY2025 revenue, ten of the world's largest healthcare companies include UnitedHealth Group, McKesson, CVS Health, Cencora, The Cigna Group, Cardinal Health, Elevance Health, Centene, Humana, and Johnson & Johnson. The ranking includes healthcare services, insurance, pharmaceutical distribution, pharmacy, and manufacturing companies.
Answer
There is no universal ranking of the “top” healthcare companies because healthcare includes several very different industries.
Using annual revenue provides one objective way to compare company scale. Based on FY2025 revenue reported for healthcare organizations in the 2026 Fortune Global 500, leading companies include:
• UnitedHealth Group
• McKesson
• CVS Health
• Cencora
• The Cigna Group
• Cardinal Health
• Elevance Health
• Centene
• Humana
• Johnson & Johnson
This list demonstrates why healthcare-company rankings should not be confused with pharmaceutical-company rankings.
Several of the largest healthcare companies primarily operate in health insurance, pharmacy benefits, or pharmaceutical distribution rather than manufacturing medicines or medical devices.
Johnson & Johnson is the highest-ranking major diversified healthcare manufacturer within this revenue-based group, with operations spanning innovative medicines and medical technologies.
Alternative rankings based on market capitalization, pharmaceutical sales, medical-device revenue, or R&D expenditure will produce very different results. The metric should therefore always be stated alongside the ranking.
