Biogen is an established biopharmaceutical company focused on treatments for neurodegenerative and rare diseases. Its declining multiple sclerosis franchise is its largest revenue generator and contributed 40% of total revenue in 2025. Biogen also generates significant revenue from its CD20 collaboration agreements with Roche (19% of total in 2025), which includes oncology drugs Rituxan and Gazyva and multiple sclerosis drug Ocrevus. Biogen's newer franchises include Spinraza (spinal muscular atrophy, with partner Ionis), Leqembi (Alzheimer's disease, collabroation revenue from its partner Eisai), Skyclarys (Friedreich's ataxia, Reata), Zurzuvae (postpartum depression, Sage), and Qalsody (amyotrophic lateral sclerosis, Ionis).

Ericsson provides telecom equipment and services that are primarily used to build and operate mobile networks. The firm divides its business into three segments: networks, cloud and software services, and enterprise. Wireless carriers have traditionally been the firm's primary customers, but it is pushing to cater more to enterprises as well, as both try to take advantage of 5G capabilities and utilize "as-a-service" communications platforms. The company also licenses its patents to handset manufacturers.
