Biogen to Acquire Apellis Pharmaceuticals for $41 per Share
Biogen (BIIB) has agreed to acquire Apellis Pharmaceuticals (APLS) for $41 per share, bringing complement inhibitors Syfovre and Empaveli into its portfolio, with Syfovre's $589M in 2025 sales viewed as the primary value driver, Chardan tells investors in a research note. The deal underscores strong pharma interest in the complement pathway, particularly in geographic atrophy, and reads positively to peers such as Annexon (ANNX) and Ocugen (OCGN), potentially catalyzing further partnership or licensing activity in the space, the firm says. Chardan has a Buy rating and $16 price target on shares of Annexon.
