Biogen Inc. (NASDAQ: BIIB) has faced steady headwinds in recent years. Revenue growth has slipped as competition in neurology and immunology intensified, and investor sentiment remains cautious. Shares trade around $150/share, down sharply from previous highs. Still, Biogen’s strong margins, cash flow, and disciplined cost management give analysts some reason for optimism.
Recently, Biogen secured FDA approval for a new weekly injectable version of Leqembi, its Alzheimer’s treatment co-developed with Eisai, improving convenience for patients and reinforcing its leadership in neurodegenerative care. The company also entered a major licensing deal to expand its immunology and rare disease pipeline, signaling a broader strategic shift beyond multiple sclerosis into high-impact neurological and immune-mediated conditions. These moves highlight how Biogen is repositioning for long-term growth while managing near-term challenges.
This article explores where Wall Street analysts think Biogen could trade by 2027. We’ve compiled consensus targets and valuation models to outline the stock’s potential path. These figures reflect current analyst expectations and are not TIKR’s own predictions.

Analyst Price Targets Suggest Modest Upside
Biogen trades at about $150/share today. The average analyst price target is near $173/share, pointing to roughly 15% upside. Forecasts show a wide range and mixed sentiment:
- High estimate: ~$260/share
- Low estimate: ~$118/share
- Median target: ~$165/share
- Ratings: 13 Buys, 3 Outperforms, 19 Holds
It looks like analysts see some room for recovery, but confidence is limited until new treatments start gaining momentum. For investors, that means the stock could stay range-bound in the near term as the market waits for clearer progress from Biogen’s Alzheimer’s and immunology portfolios.

Biogen: Growth Outlook and Valuation
The company’s fundamentals remain steady, though not particularly strong:
- Revenue is expected to decline slightly through 2027
- Operating margins are holding firm near 31%
- Shares trade around 10x forward earnings, below the biotech average
- Based on analysts’ average estimates, TIKR’s Guided Valuation Model using a 9.5x forward P/E suggests ~$153/share by 2027
- That implies about 1.8% total upside, or roughly 0.8% annualized returns
For investors, Biogen looks fairly valued at current levels. The stock’s appeal lies in its stable cash flow and profitability rather than big growth potential. It fits best as a defensive position in a biotech portfolio, offering stability while investors wait for new drugs to move the needle.

What’s Driving the Optimism?
Biogen continues to expand beyond its traditional multiple sclerosis portfolio, focusing on Alzheimer’s, depression, and rare diseases. The newly approved injectable version of Leqembi should drive wider adoption and sustained revenue growth in Alzheimer’s care. Meanwhile, the company’s late-stage assets and licensing partnerships point to a renewed focus on neuroscience and immunology innovation.
Management’s emphasis on efficiency and disciplined R&D spending supports margin stability even as revenue fluctuates. For investors, these strengths suggest Biogen is building a foundation for gradual recovery. The story is about consistency and execution, not rapid growth.
Bear Case: Slow Growth and Execution Risk
Even with these positives, Biogen’s outlook still carries uncertainty. Revenue is expected to decline slightly through 2027 as older products face patent erosion and generic competition. New therapies may take time to ramp up, and the company’s dependence on a few key drugs keeps near-term risk elevated.
For investors, the main concern is timing. Biogen’s turnaround may take longer to materialize, leaving shares relatively flat despite strong margins and a low valuation. Until new launches gain scale, upside will likely remain modest.
Outlook for 2027: What Could Biogen Be Worth?
Based on analysts’ average estimates, TIKR’s Guided Valuation Model using a 9.5x forward P/E suggests Biogen could trade near $153/share by 2027. That’s roughly in line with today’s price, indicating the stock is already trading around fair value.
While this projection assumes stability, it leaves room for improvement if Alzheimer’s sales accelerate or new therapies gain traction faster than expected.
For investors, Biogen screens as a defensive healthcare stock with strong cash flow and consistent profitability. It’s not a fast grower, but its steady fundamentals and focused strategy could make it a reliable long-term compounder if management executes well on its next phase of innovation.
