Mapped: What Will the Ashurst and Perkins Coie Merger Look Like?

Lakshana Susinthiran & Emily Turner • 2 Minute Read • 17 November 2025

Today, the news broke that Ashurst and Perkins Coie have agreed to a merger. The combination would be one of the largest in recent years, creating a firm of around 3,000 attorneys and $2.7bn in revenue, a figure that would place the merged firm in the top 20 globally by revenue.


The merger will mean yet another transatlantic combination, following A&O Shearman and HSF Kramer. Ashurst will significantly expand its presence in the United States by combining with Perkins Coie, bolstering its talent in Litigation and Corporate practices.


Using publicly-available data tracked by Pirical Legal Professionals (PLP), we've taken a look at which locations & practices would grow under the merger, and how many Partners can be expected to leave throughout the talks.
