Why Is AMLX Stock Popping 14% After Hours?

Amylyx Pharmaceuticals (AMLX) shares rose 14% after-hours as it prepares to release Phase 3 trial results for avexitide, its lead drug candidate for post-bariatric hypoglycemia. The trial's success could support a 2027 regulatory filing. AMLX has no FDA-approved therapies currently, and its cash runway extends into 2028. Mizuho raised its price target to $30, citing potential launch pricing updates.
