Leveraging a little-used Securities Act rule made freshly relevant by the ongoing U.S. government shutdown, Gossamer Bio Inc. has set terms for a $230 million IPO. The San Diego-based company, which is developing therapies primarily for immunology and inflammation, has set terms for an offering of 14.4 million shares for $16 each. Barring a reevaluation of its approach should the SEC restore normal operations, the filing will become effective Feb. 12, with Gossamer listing on Nasdaq under the symbol GOSS.
