Shearman & Sterling LLP

Offering strength in complex and contentious merger proceedings on both sides of the Atlantic, the team at Shearman & Sterling LLP  works with major US and global clients, often on a hired-gun basis, to secure approvals for deals in a diverse range of sectors, including aerospace and defense, tech, media, and financial services. The practice has deep agency experience, including former senior DOJ and FTC officials, allowing it to advise clients on agency strategy throughout Second Request proceedings and other high-stakes merger investigations and litigation. The firm handled two standout mandates for JetBlue in 2022, representing the client against the DOJ’s challenge to its alliance with American Airlines, as well as advising on its $3.8bn takeover bid for Spirit Airlines, both significant cases for key senior lawyer Jessica Delbaum . A former Chief of Staff at the Antitrust Division, global antitrust head David Higbee is noted for his expertise in regulated industry deals, representing clients before US and international antitrust agencies, while Ben Gris is another active member of the team, previously Assistant Director of the FTC’s Bureau of Competition and focusing on merger-related investigations and litigation. All lawyers mentioned are in Washington DC. Ryan Shores has left the firm.
