BIIB vs CHD Comparison

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).

Church & Dwight is the leading global producer of baking soda. Its portfolio extends beyond its legacy category to include laundry products, cat litter, oral care, deodorant, and nasal care, all sold under the Arm & Hammer brand. Its brands also include Batiste, OxiClean, Vitafusion, Hero, and TheraBreath, which, together with Arm & Hammer, account for around 70% of its annual sales and profits. Most recently, the firm added Touchland and its hand sanitizer business to its fold. Even as it works to expand its product reach, Church & Dwight still derives around 80% of its sales from its home market in the US.
