Here's a story about how to technically keep a promise while possibly breaking its spirit: A new report from Hunterbrook Media investigates how America's three biggest healthcare companies—CVS Health Corp. (CVS), UnitedHealth Group, Inc. (UNH) and Cigna Group (CI)—are allegedly using shell companies to hide billions of dollars that should be lowering drug prices for patients.

MarketDash reached out to all three companies for comment. CVS declined to comment, while Cigna and UnitedHealth did not immediately respond.

Here's what Hunterbrook claims is happening.

The Shell Game

Most Americans get their prescriptions through pharmacy benefit managers, or PBMs, which are supposed to negotiate discounts (called "rebates") with drugmakers and pass those savings along to customers. It's a middleman role that's supposed to benefit everyone.

Under pressure from new regulations and public scrutiny, these PBMs promised to pass through 100% of those rebates to their customers. Sounds great, right? But Hunterbrook alleges the big insurers found a workaround: They created secret subsidiaries called GPOs (Group Purchasing Organizations).

Here's the clever part. Instead of the PBM taking a cut of the rebate directly, the parent companies now have their GPOs collect massive "fees" from drugmakers. Meanwhile, the PBM can truthfully tell customers it passed on 100% of the rebates it received.

What they allegedly don't mention is that their own GPO—which they also own—kept billions in fees for itself. It's like promising to give someone all the money in your right pocket while quietly stuffing cash into your left pocket.

Empty Offices, Big Money

Hunterbrook reporters did some old-fashioned shoe-leather journalism, visiting the headquarters of these GPOs in Ireland, Switzerland, and Minnesota. What they found was striking: Despite handling tens of billions of dollars, the offices were largely empty.

• Zinc (CVS): A deserted suite in Minnesota with mail piling up.
• Emisar (UnitedHealth): Empty cubicles in an Irish office.
• Ascent (Cigna): A small office in Switzerland that called the police when a reporter started asking questions.

The Bottom Line

According to Hunterbrook, while the insurers claim these GPOs help lower costs, they're actually a mechanism to protect profits. The allegation boils down to this: Giant healthcare companies created what appear to be "fake" middleman companies with skeleton operations to siphon off billions in drug discounts that were supposed to benefit patients.

If true, it's a masterclass in creative accounting—and a reminder that in healthcare, following the money often requires following it through multiple shell companies across multiple continents.
