Weil, Gotshal & Manges LLP in New York has ‘subject matter experts dedicated solely to securities and corporate governance litigation, and that expertise is brought to bear both in the courtroom and boardroom’. The firm is active in the Delaware Chancery Court and the Delaware Supreme Court, though it handles matters across the country. It has carved out a leading role in SPAC-related cases, which continue to be a key facet of the market, as well as maintaining a strong track record of success in appraisal litigation. John Neuwirth (who is ‘the literal master of M&A litigation’) and Caroline Zalka jointly lead the securities litigation practice, in which many partners handle deal-related cases. Zalka is representing Warner Bros. Discovery in class actions concerning the $40bn merger between AT&T’s WarnerMedia and Discovery, Inc. Joshua Amsel and emerging partner talent Evert Christensen are ‘top-notch standouts who are equally smart, hard working, pragmatic’. In late 2023, Stefania Venezia was made up to partner in recognition of her work on securities and M&A litigation, as well as regulatory investigations. Jonathan Polkes and Stacy Nettleton departed the team in March 2025.
