Recent News and Developments

Biogen key developments throughout late 2025 reveal both opportunities and challenges. Among the most positive news, the company announced collaborations and product launches that could impact its market position significantly.

In October 2025, the company shared its third-quarter earnings, which exceeded market expectations, partially due to strong demand for Vumerity in the multiple sclerosis segment.
