Katten has built a strong reputation in regulatory investigations, securities class and derivative cases, whether for high-growth businesses to Fortune 500 companies. Working from both Los Angeles and New York, seasoned litigator and chair or the securities litigation group Bruce Vanyo remains a key adviser to some of the firm’s largest corporate clients. The firm also has strong practitioners in Chicago, where Michael Diver, a former Enforcement Branch Chief of the SEC’s Chicago office, and Michael Lohnes are the key contacts. Christina Costley is a notable member of the LA team, and she worked closely with Vanyo on the defense of Natera, Inc, which faced allegations of making misleading statements in its public disclosures concerning the accuracy of its testing technology and its growth projections. Experienced litigator Kevin Broughel joined the firm in March 2024, in the firm's New York office.
