Arthur J. Gallagher & Co. disclosed that one of its directors acquired additional exposure to the company’s stock through its Director Deferral Plan. On 12/01/2025, the director acquired 162.536 shares of common stock at $246.1 per share, reported as an acquisition rather than a sale. This increased the director’s beneficial ownership to 9,110.532 shares, held as a direct position.

The filing explains that this transaction stems from a prior election to defer the director’s annual cash retainer into deferred share units, which the company credits on a quarterly basis and will ultimately distribute in the form of common stock. This reflects compensation being taken in equity-linked form rather than cash, aligning part of the director’s pay with the company’s share performance.
