Rising Drug Pricing Pressures And Generic Competition Will Depress Prospects

Key Takeaways

• Heightened pricing pressures, stricter reimbursement, and payer resistance threaten both revenue growth and the profitability of existing and new therapies.
  
• Intensifying competition, shifting innovation trends, and pipeline challenges risk eroding market share, margins, and long-term financial stability.
  
• Strong new drug launches, successful pipeline diversification, and global expansion are offsetting legacy drug declines and supporting long-term revenue, margin, and cash flow growth.

Catalysts

Biogen Inc. discovers, develops, manufactures, and delivers therapies for treating neurological and neurodegenerative diseases in the United States, Europe, Germany, Asia, and internationally.

• Increasing drug pricing scrutiny and global healthcare cost containment efforts are expected to significantly constrain Biogen's ability to achieve or sustain premium pricing on new and existing therapies, directly undermining revenue growth and net margins as payers grow more resistant to high-cost neurodegenerative disease treatments.
  
• The strain of aging populations on public healthcare budgets is likely to drive stricter reimbursement criteria and slower adoption of costly novel drugs, meaning Biogen's growth products could face significant access barriers and limited market penetration, ultimately restricting future revenue expansion.
  
• Biogen faces escalating competition from generics and biosimilars, especially as key products such as Tecfidera and Tysabri lose exclusivity internationally causing rapid erosion in branded product revenue and lower overall profitability due to shrinking gross margins.
  
• The biotechnology landscape is shifting toward personalized medicine and advanced cell/gene therapies, which risks making Biogen's traditional small molecule and biologics portfolio increasingly obsolete, leading to potential long-term declines in both market share and premium pricing power.
  
• Ongoing clinical trial setbacks or delays in Biogen's core neurology pipeline, especially in high-profile areas like Alzheimer's and Parkinson's, threaten to inflate research expenses without delivering offsetting revenue, resulting in impaired R&D returns and diminishing earnings and cash flow over the coming years.

Biogen Future Earnings and Revenue Growth

Assumptions

• This narrative explores a more pessimistic perspective on Biogen compared to the consensus, based on a Fair Value that aligns with the bearish cohort of analysts.
• The bearish analysts are assuming Biogen's revenue will decrease by 4.9% annually over the next 3 years.
• The bearish analysts assume that profit margins will increase from 15.3% today to 19.6% in 3 years time.
• The bearish analysts expect earnings to reach $1.7 billion (and earnings per share of $11.27) by about August 2028, up from $1.5 billion today. The analysts are largely in agreement about this estimate.
• In order for the above numbers to justify the price target of the more bearish analyst cohort, the company would need to trade at a PE ratio of 12.6x on those 2028 earnings, up from 12.5x today. This future PE is lower than the current PE for the US Biotechs industry at 13.2x.
• Analysts expect the number of shares outstanding to grow by 0.65% per year for the next 3 years.
• To value all of this in today's terms, we will use a discount rate of 7.19%, as per the Simply Wall St company report.

Biogen Future Earnings Per Share Growth

Risks

• Biogen is experiencing strong growth in new product launches such as LEQEMBI, SKYCLARYS, VUMERITY, and ZURZUVAE, which are more than offsetting declines in legacy multiple sclerosis drugs, supporting revenue stability and potential growth in the future.
  
• The Alzheimer's market is expanding with enhanced infrastructure and adoption of blood-based biomarkers, and Biogen's LEQEMBI holds a dominant 70% share, bolstered by upcoming convenience-enhancing formulations like subcutaneous and at-home options, which may drive further uptake and accelerate revenue growth.
  
• Biogen is making significant progress in diversifying and advancing its pipeline with multiple phase III programs in key therapeutic areas including lupus, neurology, nephrology, and rare disease, which reduces reliance on older products and enhances long-term earnings potential.
  
• International growth is accelerating, with SKYCLARYS now launched in 29 markets and positive reimbursement trends in Europe and Brazil, meaning expanding geographic reach could support sustained revenue and cash flow strength despite competitive pressures in established markets.
  
• The company has implemented disciplined cost controls and operational restructuring, achieving savings while maintaining robust R&D investment and improving commercial execution, which positions net margins and free cash flow to benefit over the long term.

Valuation

• The assumed bearish price target for Biogen is $115.0, which represents the lowest price target estimate amongst analysts. This valuation is based on what can be assumed as the expectations of Biogen's future earnings growth, profit margins and other risk factors from analysts on the more bearish end of the spectrum.
  
• However, there is a degree of disagreement amongst analysts, with the most bullish reporting a price target of $260.0, and the most bearish reporting a price target of just $115.0.
  
• In order for you to agree with the bearish analysts, you'd need to believe that by 2028, revenues will be $8.6 billion, earnings will come to $1.7 billion, and it would be trading on a PE ratio of 12.6x, assuming you use a discount rate of 7.2%.
  
• Given the current share price of $130.67, the bearish analyst price target of $115.0 is 13.6% lower. Despite analysts expecting the underlying buisness to improve, they seem to believe the market's expectations are too high.
  
• We always encourage you to reach your own conclusions though. So sense check these analyst numbers against your own assumptions and expectations based on your understanding of the business and what you believe is probable.
