GlobalData lead analyst Aurojyoti Bose said: “Gibson, Dunn & Crutcher was the only adviser with double-digit deal volume in Q1 2026. Apart from leading by volume, it also held ninth position by value during the quarter.

“Meanwhile, Kirkland & Ellis advised on a relatively lesser number of deals but managed to lead by value due to its involvement in some big-ticket deals. Three of the five deals advised by it during Q1 2026 were billion-dollar deals, including a mega deal valued at more than $10bn.”
