Edwards Gibson data featured in Law.com commentary on how Big Law mergers are fueling Partner exits

The turbulence is reflected in the UK lateral market and data by Edwards Gibson, which saw a record‑breaking 668 partner moves in 2025 — the highest number ever recorded in a single year, and 21% above the previous record of 551 set in 2024. While most moves are not merger‑driven, recruiters agree that combining firms face heightened vulnerability. Cultural uncertainty, shifting strategy, structural integration challenges and opportunistic rival firms all play a part. The exits at A&O Shearman—nearly 200 partners globally since the merger—illustrate the scrutiny and sensitivity surrounding major combinations.

Edwards Gibson’s director, Scott Gibson, features prominently in the analysis, noting that “any form of merger will increase attrition.” He highlights that the wave of fully integrated mergers—not verein structures—creates deeper cultural and structural friction, intensifying partner anxiety and making merging firms prime targets for predatory hiring. Gibson’s commentary highlights a key paradox: firms merge to strengthen themselves against talent loss, yet the process of merging can itself trigger the very attrition they hope to avoid.
