Johnson & Johnson (JNJ) vs UnitedHealth Group Incorporated (UNH)

Johnson & Johnson is the world’s largest and most diversified healthcare company. Its operations are organized into two segments: Innovative Medicine and MedTech, which together account for all revenue following the 2023 separation of its consumer health business, Kenvue. After restructurings completed in 2023 and 2024, the pharmaceutical segment is focused on three core therapeutic areas: immunology, oncology, and neurology. From a geographic perspective, slightly more than half of the company’s total revenue comes from the United States.

UnitedHealth Group Incorporated is among the world’s largest private health insurers, providing medical benefits to roughly 51 million members globally as of December 2025, including about 1 million outside the United States. A leading provider of employer-sponsored, self-directed, and government-supported health plans, the company has built substantial scale in the medical insurance market. In addition to its core insurance operations, UnitedHealth’s Optum businesses expand its reach across healthcare services, spanning pharmacy benefits, outpatient care, and analytics for affiliated organizations and third-party clients.
