A&O Shearman’s global antitrust head David Higbee has left the firm to join Paul Weiss in Washington DC, in one of the highest profile US departures for the firm since the completion of its merger in May 2024.
Higbee is joining Paul Weiss alongside fellow antitrust partners Ben Gris and Djordje Petkoski. Between them, the trio advise on matters including merger control, government and internal investigations, and complex litigation, with their experience spanning industries from energy, to technology, life sciences and defence.
