Correction: A previous version of this story incorrectly said that Jeffrey Saper led the Wilson Sonsini transaction on his own. Saper was instead co-lead with San Diego-based partner Dan Koeppen.
SAN FRANCISCO — Wilson Sonsini Goodrich & Rosati advised San Diego-based Pfenex Inc. in its initial public offering, as the company listed itself on the New York Stock Exchange July 24. The clinical stage biotechnology company registered 8.3 million shares of common stock at a price of $6 per share, though the shares opened and remained below that price, becoming the latest biotech offering to underperform.
