The Cigna Group is best understood as a pharmacy-services company attached to an employer health benefits business. Evernorth Health Services, built around the 2018 Express Scripts acquisition, generates most of the revenue, while Cigna Healthcare serves about 18.4 million medical customers in the U.S. and abroad (June 30, 2026). The company counted about 182.8 million total customer relationships at mid-2026 and is based in Bloomfield, Connecticut.
Cigna makes money in two ways. Evernorth Health Services, the larger business by revenue, runs Express Scripts pharmacy benefit management, Accredo specialty pharmacy, home-delivery pharmacy, eviCore utilization management and MDLive virtual care; it earns dispensing margins, administrative and service fees, and purchasing economics on prescription drugs for health plans and employers. Cigna Healthcare sells employer and individual health coverage in the U.S. and internationally. Most of its U.S. medical customers are in self-funded (ASO) plans, where the employer pays claims and Cigna collects fees for networks, claims processing and care management, while insured plans earn premiums. In October 2025 Cigna announced a rebate-free Express Scripts model that shifts pharmacy economics toward upfront discounts and transparent fees.
