CVS Health just scored a big win by landing a pharmacy benefits contract with Calpers, California’s massive public employee retirement system. They beat out rival UnitedHealth for the deal, which means CVS’s Caremark division will now manage prescription drug coverage for hundreds of thousands of state workers and retirees.

Editor’s Note: This isn’t just another corporate contract—it’s a major shift in who controls prescription benefits for a huge chunk of California’s workforce. Calpers is one of the biggest public pension funds in the U.S., so this deal solidifies CVS’s grip on the pharmacy benefits market while dealing a blow to UnitedHealth’s ambitions in the space. For everyday folks, it could mean changes in how they access medications, depending on how CVS structures the plan. Bottom line: It’s a power move in the ongoing battle over who gets to manage America’s prescription drug spending.
