What the Analysts think about Biogen
Analyst ratings (Buy, Hold, Sell) for Biogen stock.
Bulls say / Bears say
In July 2025, Biogen announced a $2 billion investment to expand its North Carolina manufacturing plants—adding fill-finish, automation, and AI systems—to boost domestic production ahead of possible U.S. drug tariffs.
In August 2025, the FDA approved an at-home, weekly injectable version of Leqembi—called Leqembi IQLIK—making treatment easier to administer and expected to increase patient adoption.
In April 2025, the European Commission approved Leqembi for early-stage Alzheimer’s, making it the first EU-approved drug targeting the root cause of the disease, with analysts projecting peak sales of over $900 million in the 2030s.
In Q1 2025, Biogen’s multiple sclerosis drug sales fell by 11%, putting more pressure on its main business as competition increases.
The company booked a $165 million licensing charge in Q1 2025 from a deal with Stoke Therapeutics, leading it to lower its full-year EPS guidance to $14.50–$15.50.
Leqembi brought in just $52 million in U.S. sales for Q1 2025, showing sluggish uptake due to ongoing concerns about pricing, effectiveness, and required monitoring for side effects.
