Express Scripts
Express Scripts is a pharmacy benefit manager (PBM) that administers prescription drug benefits for health plans, employers, unions, and government programs in the United States, processing claims, negotiating drug prices with manufacturers, and operating mail-order and specialty pharmacies to enhance medication access and affordability.[1][2] Founded in 1986 and originally headquartered at 1 Express Way in St. Louis, Missouri, the company grew through acquisitions into one of the largest PBMs, handling tens of millions of members before its $67 billion acquisition by Cigna Corporation in December 2018, after which it integrated into Cigna's Evernorth division while retaining its brand for PBM services.[3][4][5] Express Scripts' core operations include developing formularies to guide drug coverage, leveraging its pharmacy network for retail fills, and providing home delivery for maintenance medications, which collectively aim to reduce overall pharmaceutical spending through volume-based rebates and generic promotion—saving clients an estimated $38 billion annually in self-reported figures prior to the merger.[6][7] The firm has achieved scale with pre-acquisition revenues exceeding $100 billion and a workforce of about 26,600 employees, enabling it to influence drug utilization patterns and negotiate directly with pharmaceutical suppliers.[8][3] Notable for its data-driven approaches to adherence and cost containment, Express Scripts has nonetheless encountered significant controversies over PBM industry practices, including opaque rebate retention, spread pricing between reimbursements and pharmacy payments, and potential incentives that prioritize high-cost drugs, prompting federal investigations and legislative scrutiny into whether such mechanisms truly lower net costs or exacerbate affordability issues for patients.[9][10] These debates highlight causal tensions in the supply chain, where PBMs' intermediary role facilitates discounts from manufacturers but has been empirically linked in some analyses to sustained list price inflation and pharmacy margin squeezes.[9]
