This week, I’m rerunning some popular posts while I prepare for tomorrow’s live video webinar: Drug Channels Outlook 2026 .

Vertical integration continues to reshape U.S. healthcare, as detailed in DCI’s new 2025-26 Economic Report on Pharmaceutical Wholesalers and Specialty Distributors.
Our latest analysis shows how the Big Three companies—Cencora, Cardinal Health, and McKesson—are extending their reach far beyond drug distribution, building influence throughout the drug channel.
In recent years, these companies have spent more than $16 billion to acquire management service organizations (MSOs) that oversee physician practices in such specialties as gastroenterology, oncology, ophthalmology, and urology.
Below, we highlight the largest MSO transactions and explore five ways wholesalers benefit from ownership in their downstream physician customers. Ultimately, these strategies may allow wholesalers to exert unprecedented control over market access for provider-administered drugs—if they can figure out how to realize this power.
Today’s post is adapted from Section 6.3.2. in DCIs 2025-26 Economic Report on Pharmaceutical Wholesalers and Specialty Distributors.
