AI Summary
Biogen's thesis has shifted from a steady MS royalty engine to a binary, event‑driven equity where near‑term value depends on successful commercialization of recent launches (LEKEMBI, SKYCLARYS, ZURZUVAE) and positive late‑stage readouts (IQLIK, litifilimab, high‑dose SPINRAZA), making the stock a hold/watch until clear payer adoption and regulatory wins de‑risk the pipeline. Actively monitor LEKEMBI Medicare/Part D access and the H2‑2026 readout schedule—meaningful acceleration in payer coverage or successful FDA decisions would be the clearest buy signals, while negative readouts or narrowed access should trigger downside defense.
