Ziebell William F 4

What Happened

• William F. Ziebell, Vice President at Arthur J. Gallagher & Co. (AJG), had performance/phantom awards vest on March 15, 2026 and reported the conversion/exercise of those derivative units into common stock. The filing shows 6,930 shares acquired as an award (A) and related exercise/conversion entries (M). To satisfy tax withholding, 2,321 shares were disposed at $207.93 per share, totaling approximately $482,606 (F).
• This was primarily an award/vesting event (not a buy for market exposure). The disposal of 2,321 shares reflects withholding to cover taxes owed on the vested award, effectively a cashless/net settlement of part of the award.

Key Details

• Transaction date: March 15, 2026 (Form filed March 18, 2026; filing was one day late — footnote F1).
• Primary amounts: 6,930 shares acquired via award/conversion; 2,321 shares disposed for tax withholding at $207.93 each = ~$482,606.
• Transaction codes: A = award/grant (vesting of PSUs/phantom stock), M = exercise/conversion of derivative, F = shares withheld to pay tax liability.
• Shares owned following the transactions: Not provided in the supplied excerpt of the filing.
• Relevant footnotes: F2 (PSUs awarded 3/15/2023 vested 3/15/2026); F3/F9 (phantom/notional units represent rights to one share each); F4 (Age 62 deferred compensation elections referenced); F10 (some notional units payable upon separation).
• Filing timeliness: Marked late (filed one day after the report date) per F1.

Context

• This was mainly a vesting/conversion of performance/phantom units into common stock. The withholding of 2,321 shares to cover taxes is a routine, non-market-sale settlement (a cashless/net withholding), not a discretionary open-market sale.
• For retail investors: vesting/employment-related conversions are common and do not necessarily signal buying or selling intent; the only shares leaving Ziebell’s holdings in this event were withheld to cover taxes.
