Key Highlights

Core Q1 performance drivers and headwinds for Biogen include the following: First, legacy MS portfolio pressure: Sales of blockbuster MS drugs Tecfidera and Tysabri are expected to decline sequentially, hit by global generic competition for Tecfidera and European biosimilar competition for Tysabri, with consensus estimates pegging Tecfidera Q1 sales at $111 million and Tysabri at $359 million.

Expert Insights

Biogen’s 58.1% 12-month trailing return, compared to a 22.3% gain for its peer biotech group, reflects investor optimism that the firm has successfully pivoted away from its historical overreliance on its declining legacy MS franchise, though the Q1 print will be a key test of that thesis. While consensus estimates already price in double-digit year-over-year declines for Tecfidera and Tysabri, any larger-than-expected erosion in MS revenues could trigger near-term downside volatility, particularly given Biogen’s current Zacks Rank 3 (Hold) and negative Earnings ESP, which indicates that recent analyst estimate revisions have trended lower ahead of the print, with the most accurate EPS estimate currently sitting at $2.90, 2.17% below consensus. The upcoming Apellis acquisition is a critical strategic inflection point for Biogen, as it diversifies the firm’s portfolio into high-growth, high-margin rare disease and ophthalmology segments, reducing exposure to the increasingly crowded MS and Alzheimer’s markets. Management’s commentary on expected synergy realization, integration timelines, and long-term growth targets for the Apellis assets will be far more important to medium-term price action than the Q1 top-line and EPS results themselves, in our view. We also see moderate upside risk to consensus Zurzuvae and Skyclarys sales estimates, as both drugs have limited direct competition in their respective orphan indications, and Zurzuvae’s first-to-market status for postpartum depression has driven stronger-than-expected prescription volumes in recent months. The IRA tailwind for Vumerity is also likely to be a multi-year growth driver, as the Part D redesign reduces patient out-of-pocket costs for oral MS therapies, driving higher adherence and payer coverage for Vumerity relative to older, cheaper generic alternatives. For investors looking for biotech names with higher odds of a Q1 earnings beat, we highlight Regeneron Pharmaceuticals (REGN), which carries a Zacks Rank 3 and a positive Earnings ESP of +5.87%, and is also scheduled to report results on April 29. Regeneron has returned 27.2% over the past 12 months, with an average four-quarter earnings surprise of 22.92%. (Word count: 1192) Biogen Inc.
