Leaving the ACA Individual Market
Cigna announced with its first-quarter 2026 results that it will stop selling individual and family plans, on and off the exchanges, in all 11 states where it participates. About 369,000 people were enrolled. The company cited rising use of care and a smaller, sicker market after the expanded premium tax credits expired (source). Our report on 2027 Marketplace exits covers the state-by-state impact.
Employer Coverage
Cigna’s core business is employer coverage, much of it self-funded plans that Cigna administers. It is the largest commercial insurer in Wyoming and the second-largest in Montana, New Hampshire, Tennessee and Vermont in the AMA’s 2024 data.
Express Scripts
Express Scripts is one of the three largest pharmacy benefit managers. It settled the FTC’s insulin pricing case in February 2026 without a penalty or admission, and is moving to a rebate-free fee model for many clients starting in 2027 (source). Our PBM guide explains why those changes matter.
