The company expects significant erosion of Tecfidera’s sales in the United States in 2021. The guidance also assumes significant erosion of Rituxan in the United States. The guidance assumes modest revenues from Aduhelm in 2021.The earnings per share guidance was maintained in the range of $17.50-$19.00. Capital expenditures are anticipated between $375 million and $425 million.Adjusted R&D expenses are expected to be between $2.45 billion and $2.55 billion (previously $2.3 billion and $2.4 billion) and adjusted SG&A cost guidance was maintained between $2.6 billion and $2.7 billion. R&D and SG&A costs are expected to be higher in the second half compared with the first due to new collaborations, program readouts, and investments for Aduhelm.The reduction in revenues from Tecfidera and Rituxan, both high margin products, is expected to put pressure on gross margins in 2021.Our TakeBiogen beat estimates on both counts.

Biogen’s stock has risen 31.9% this year so far against a decrease of 1.1% for the industry Image Source: Zacks Investment ResearchAduhelm’s FDA approval faced a lot of criticism as some analysts believed the drug was not backed by strong evidence of efficacy. Aduhelm also comes with a hefty price tag of $56,000 a year, which was widely condemned.The FDA approved Aduhelm despite an FDA advisory committee voting against its approval in November last year due to mixed outcomes data from ENGAGE and EMERGE phase III studies.In an open letter to Alzheimer’s disease community issued along with the results, Biogen defended Aduhelm’s approval saying that it was based on extensive data. Biogen, in the open letter, called for a “formal review” of the regulatory process that led to accelerated approval.Meanwhile, multiple generic versions of blockbuster drug, Tecfidera have been launched, which are significantly eroding the drug’s sales and the company’s overall topline. Sales of Spinraza are being hurt due to COVID-19 and the drug’s competitive environment is also getting challenging.Biogen has a Zacks Rank #3 (Hold) currently.
