Johnson & Johnson

These now represent all of the company's sales following the divestment of the consumer business, Kenvue, in 2023. After restructurings in 2023-24, the drug division focuses on three main therapeutic areas: immunology, oncology, and neurology. Geographically, just over half of total revenue is generated in the United States.
