Expert Insights

RBC Capital Markets analyst Brian Abrahams noted Biogen now has multiple identifiable upside catalysts following several years of operational turbulence, writing in a client note that “tailwinds abound” for the biotech. This marks a material shift for Biogen, which faced widespread investor skepticism over its Alzheimer’s strategy as recently as 2025, when Leqembi launch uptake trailed initial projections. The upcoming $5.6 billion acquisition of Apellis Therapeutics will add two marketed immune-modulating assets to Biogen’s portfolio, reducing near-term revenue risk, while upcoming Phase 3 readouts for tau-targeting Alzheimer’s asset BIIB080, plus antibody candidates litifilimab and felzartamab, offer material upside if successful. Cantor Fitzgerald analyst Eric Schmidt noted investor sentiment on Biogen is shifting away from concerns over legacy MS revenue erosion to pipeline upside, a notable reversal after three years of lackluster share performance. For peers, Cantor’s Carter Gould noted Bristol Myers’ Q1 beat was “overwhelmingly driven” by legacy assets including blood thinner Eliquis and oncology drugs Revlimid and Pomalyst, which beat consensus estimates by 8%, 22% and 49% respectively, offsetting 5% misses for key growth assets Opdivo and Reblozyl. William Blair’s Matt Phipps noted Bristol Myers has one of the sector’s most impactful H2 2026 catalyst calendars, with readouts for anticoagulant milvexian, blood cancer therapies iberdomide and mezligdomide, and an Alzheimer’s psychosis indication for Cobenfy set to determine its long-term growth trajectory, though Raymond James analyst Sean McCutcheon warned long-term revenue visibility remains limited until those readouts are released in Q4. For Regeneron, Leerink Partners analyst David Risinger noted Eylea HD’s $468 million Q1 sales missed consensus estimates by 12%, with manufacturing delays for its pre-filled syringe formulation coming as five biosimilars are set to launch in H2 2026, pressuring the company’s core revenue stream. The Phase 2 failure of fianlimab in lung cancer also raises questions over the asset’s upcoming Phase 3 readout in melanoma, with both RBC’s Abrahams and Leerink’s Risinger cutting their price targets for Regeneron, noting the company may need to pursue targeted business development acquisitions to offset pipeline gaps.
