These shares represent awards under the Age 62 Plan, a nonqualified deferred compensation plan of the Company, which have been deemed invested in Company common stock at the election of the reporting person. Participants vest in these awards when they attain age 62, or after a one-year period for participants who have attained age 61.
Someone high up at Arthur J. Gallagher & Co. told the SEC they plan to sell $3.8M of Arthur J. Gallagher & Co. shares around Sep 15, 2026. The shares did not come from their pay.
