Big picture: In 2026-27, we think BIIB stock could climb higher on the resiliency of the commercial

franchise (e.g. Leqembi, Skyclarys, Spinraza, Zurzuvae) or on any (+) Phase II/III success, especially

since each late-stage program offers $1B+ in blockbuster potential. Ultimately, having 1-2 pipeline

products approved should enable BIIB's overall topline revenues to grow over the long-term (a key

stock driver). The recent APLS acquisition for Syfovre/Empaveli will also help with near-term topline

growth, delivering meaningful EPS accretion starting in 2027.

The Phase IIb LUMA study of BIIB122/DNL151 (oral LRRK2) missed the primary and secondary

endpoints in early-stage Parkinson's disease (N=650). (a)Early-stage Parkinson's disease (PD)

patients with and without LRRK2 mutations were randomized 1:1 to receive either BIIB122 225mg
