Quinn Emanuel Urquhart & Sullivan, LLP

Litigation heavyweight Quinn Emanuel Urquhart & Sullivan, LLP is well-placed to provide excellent insight to defendant companies in securities class actions. The team integrates trial and appellate specialists at an early stage of the litigation life-cycle, ensuring that it is well-equipped for both trial or appeals, should they arise. This approach notably helped secure a high-profile victory in a rare securities jury trial (subsequently affirmed on appeal) on behalf of Tesla and Elon Musk. New York-based practitioners Andrew Rossman and the ‘incredibly smart’ Jesse Bernstein had a pivotal involvement in the aforementioned case, with Rossman also noted for his broader M&A litigation expertise. The firm’s Los Angeles headquarters also houses numerous high-profile securities litigators, including team head Harry Olivar and the ’exceptional’ Brian Timmons, who is particularly skilled at handling cases involving private investment funds. Michael Swartz joined the team in March 2025 from McDermott Will & Schulte.
