This 424B5 filing finalizes the terms of a new At-The-Market (ATM) offering under the S-3ASR shelf registration filed earlier today, May 4, 2026. The company is authorized to sell up to $350 million in common shares from time to time, which could result in significant dilution for current shareholders, estimated at over 24% based on current outstanding shares. While ATM offerings provide financial flexibility for biopharmaceutical companies like Biohaven to fund ongoing operations and pipeline development, the substantial size of this offering creates an overhang on the stock. Investors should monitor the pace and pricing of future share sales under this program.
