Metsera (MTSR) said late Thursday it priced its initial public offering of about 15.3 million common shares at $18 per share for expected gross proceeds of $275 million.

The biotechnology company granted the underwriters a 30-day option to purchase up to roughly 2.3 million additional shares.

Closing of the offering is expected to occur on Feb. 3, subject to customary conditions.

The shares are expected to begin trading on the Nasdaq Global Select Market on Friday under the ticker "MTSR."
