The partners at Simpson Thacher & Bartlett LLP are ‘subject matter experts who provide timely, practical advice that allows the clients to make risk-based decisions’. The firm, which is described as ‘a litigation powerhouse, both inside Delaware and outside of it’, frequently acts for issuers and their boards of directors, special committees, private equity firms and other financial sponsors. The vastly experienced Jonathan Youngwood and renowned trial lawyer Lynn Neuner lead the M&A litigation group. Having played a key role in the case that opened up the slew of SPAC-related litigation, acting for client Multiplan, the firm remains active in that space with Youngwood and Craig Waldman advising Paysafe in a case concerning its 2021 merger with Foley Trasimene Acquisition Corp. II, in which the company was valued at $9bn. The ‘exceptional’ Peter Kazanoff is currently defending Convey Health Solutions in shareholder litigation arising from TPG’s proposed take-private transaction, in which plaintiffs alleged breach of fiduciary duty. James Kreissman and Palo Alto-based Stephen Blake also play pivotal roles in many of the firm’s most prominent cases.

Legal 500 Editorial commentary

Testimonials

Collated independently by Legal 500 research team.

  • ‘The lawyers with whom we work at Simpson are subject matter experts and provide timely, practical advice that allows the Company to make risk-based decisions. Their advice is neither too conservative nor too permissive/expansive, which helps enormously when I am trying to evaluate the risk presented by a particular course of action or decision. They help define the risk continuum and its consequences.’

  • ‘Particularly as it relates to securities litigation, Pete Kazanoff is exceptional in terms of practicality in staffing and approach. He is keenly aware of the need to balance doing what needs to be done to protect the Company with the cost/benefit of doing so. Sara Razi is very similar in her approach to antitrust matters.’

  • ‘STB is a litigation powerhouse, both inside Delaware and outside of it.’

  • ‘Peter Kazanoff and Janet Gochman are extremely talented, effective and practical attorneys, who understand how to secure the optimal outcome for their clients rather than applying a one-size-fits-all approach to litigation.’
