Analysis · AMLX · Life Sciences
Amylyx priced its public offering at $35.50 per share, raising $500.2 million before fees — a 43% increase from the $350 million initially announced two days ago. The deal was upsized on the back of positive Phase 3 LUCIDITY data for avexitide, which sent the stock up 63% to a 52-week high. The offering adds roughly 12.7% to the share count, diluting existing holders, but the capital funds the commercial launch of avexitide if approved. Underwriters Leerink, Morgan Stanley, Guggenheim, and LifeSci Capital have a 30-day option for 2.1 million more shares, which could push total proceeds to $575 million. The pricing at $35.50 versus the August 18 close of $35.11 shows strong institutional demand, but the dilution is real and immediate.
