#Biogen Latest

Biogen has reported a strong performance for Q2 2025, showcasing an adjusted EPS of $5.47 and revenues approximating $2.6 billion, both of which exceeded expectations. Investor confidence was boosted by robust growth in Biogen’s newer drugs: Leqembi (U.S. sales $63 million; global in-market sales $160 million, including a $35 million shipment to China), Skyclarys ($130 million globally), and Zurzuvae ($46 million), all of which posted strong sequential growth in Q2 2025.

Following these results, Biogen raised its full-year 2025 adjusted EPS guidance from $14.50–$15.50 to a new range of $15.50–$16.00. It also revised its revenue outlook to remain approximately flat year-over-year on a constant currency basis, improving from its previous forecast of a mid-single-digit decline.

Although traditional multiple sclerosis treatments are experiencing a decline due to competitive pressures, the company's strategic cost-saving efforts and a robust pipeline foster optimism. Analysts offer mixed perspectives; some maintain Buy ratings while others highlight ongoing challenges in the core MS market.
