In another big move to boost its ranks in U.S. transactional work, Magic Circle firm Freshfields Bruckhaus Deringer has picked up mergers and acquisitions partner Peter Lyons from Shearman & Sterling, where he worked for more than three decades.

Lyons is joining Freshfields as a U.S. M&A partner and cohead of the firm’s global public M&A group. The hire, announced Tuesday, is a major coup for Freshfields, a global leader in cross-border M&A that has been trying to establish itself as a player on this side of the pond. Last week, the firm announced the hires of Mitchell Presser, a longtime Wachtell, Lipton, Rosen & Katz partner who went on to cofound Paine & Partners, and James Douglas, who had served as Skadden, Arps, Slate, Meagher & Flom’s banking practice head. Both joined Freshfields as leaders of the M&A and leveraged finance groups, respectively.
