Charter has taken Express Scripts to court, accusing the pharmacy-benefit manager of holding back millions in drug rebate payments tied to prescription claims from 2020 through 2022. The complaint, reported April 27, 2026, was filed in St. Louis, dropping a new legal fight into a city already familiar with PBM drama.
According to St. Louis Business Journal, the suit says the unpaid rebate dollars are linked specifically to prescription drug claims from 2020 to 2022 and seeks recovery of millions of dollars Charter argues it is owed under the parties’ contract. The filing names Express Scripts, now operating as Evernorth within Cigna, as the defendant in the contract dispute.
Regulatory Backdrop: FTC Deal Raises the Stakes
The complaint lands at a time when PBMs are already under heavy regulatory and legal fire. In February 2026, the Federal Trade Commission announced a settlement with Express Scripts aimed at curbing long-standing rebate-driven formulary practices, and reporting at the time described the deal as a watershed moment for how rebates are handled. Coverage by Healthcare Dive noted the settlement’s potential ripple effects across employer plans and PBM contracts.
Local Stakes in St. Louis
Express Scripts has deep operational ties to St. Louis, so this latest suit keeps the company firmly planted in local legal headlines. Hoodline recently reported that Jefferson County set a March 2027 trial date in a separate case against Express Scripts and Optum Rx, a reminder that PBM litigation is playing out across courtrooms in the region and not just in abstract policy debates.
