Securities litigation: defense

Katten

Plus d’information
Katten is a popular choice among financial institutions, asset managers, public companies and their executives, in the defense of a wide range of securities class actions, stockholder derivatives cases, M&A litigation, proxy disclosure suits and SEC investigations and enforcement actions. The life sciences sector remains a fertile source of work, with New York-based Bruce Vanyo regularly defending high-profile sector specific issuers, including with regard to cases brought following alleged misstatements (including with regard to clinical trials) and subsequent stock price drops. Chicago-based Michael Diver co-chairs the team alongside Vanyo and leverages his previous experience at the SEC to good effect to clients facing enforcement actions from the regulator, including with regard to financial fraud, market manipulation and insider trading. The arrival in March 2024 of New York-based Kevin Broughel from Paul Hastings LLP strengthens the team in light of his deep understanding of the financial markets, products and regulations, and for matters involving cross-border issues.
