The SEC has settled insider-trading charges against Weizheng Zeng in an administrative proceeding arising from the acquisition of Chimerix, Inc. by Jazz Pharmaceuticals plc. In SEC v. Weizheng Zeng (File No. 3-22627), the agency alleged that Zeng traded Chimerix stock while participating in due diligence work connected to Jazz’s acquisition of the company, before the deal was publicly announced on March 5, 2025.

According to the SEC, those trades generated roughly $69,011 in illicit profits.
