(BIIB) is a global biotechnology company that discovers, develops, and delivers therapies for neurological, autoimmune, and rare diseases across the United States, Europe, and other international markets.

For fiscal 2026, analysts project Biogen to post adjusted EPS of $15.70, a 2.8% rise from $15.28 in fiscal 2025.

BIIB stock has soared 54.2% over the past 52 weeks, outpacing the S&P 500 Index's ($SPX) 34.3% gain and the State Street Health Care Select Sector SPDR ETF's (XLV) 9.5% rise over the same period.

Shares of Biogen surged 8.5% on Feb. 6 after the company reported Q4 2025 revenue of $2.3 billion and adjusted EPS of $1.99, both topping consensus. Strong product performance, especially Leqembi generating about $134 million in sales with ~54% year-over-year growth and Zurzuvae adding ~$65.7M with nearly threefold growth, helped offset a ~14% year-over-year drop in multiple sclerosis revenue to $917.2 million.

Investor sentiment was further lifted as full-year revenue reached $9.9 billion with EPS of $15.28 above prior outlook, and 2026 EPS guidance of $15.25 - $16.25 came in ahead of the consensus despite a projected mid-single-digit revenue decline.

Analysts' consensus rating on BIIB stock is cautiously optimistic, with a "Moderate Buy" rating overall. Out of 34 analysts covering the stock, opinions include 14 "Strong Buys,” one "Moderate Buy," and 19 "Holds." The average analyst price target for BIIB is $208.31, suggesting a potential upside of 13.8% from current levels.
