This mega-deal handed Endeavor a commanding 51% stake in the newly formed TKO Group Holdings, while existing WWE shareholders retained a solid 49%. What's more, it orchestrated a significant reshuffle in the corporate hierarchy. Vince McMahon, the legendary WWE chairman and CEO, assumed the mantle of executive chairman for TKO Group Holdings, while Nick Khan, the former WWE CEO, donned the hat of WWE's president. Dana White, the charismatic president of UFC, continued to steer the ship for the MMA powerhouse.
