Ziebell William F 4

What Happened

• William F. Ziebell, Vice President of Arthur J. Gallagher & Co. (AJG), converted/exercised 50.921 deferred/phantom shares into common stock on 2026-03-31. The shares were valued at $215.95 each, totaling about $10,996. The same 50.921 shares were then withheld/disposed to satisfy employment tax withholding, leaving no net new shares delivered to the reporting person.

Key Details

• Transaction date: 2026-03-31; Form 4 filed 2026-04-02 (timely).
• Price/value used: $215.95 per share; total value ≈ $10,996.
• Shares acquired (conversion/exercise): 50.921 (code M). Shares disposed to cover taxes: 50.921 (code F).
• Shares owned after transaction: not specified in the filing.
• Relevant footnotes: F1/F2 — these were phantom/deferred stock awards under the Age 62 Plan (nonqualified deferred compensation); participants vest at age 62 (or after a one‑year period if age 61). Remark states the transaction “relates solely to the withholding of shares to cover employment taxes with respect to the vesting of shares under the Age 62 Plan.”
• Transaction codes: M = exercise/conversion of derivative; F = payment of exercise price or tax liability (withholding).

Context

• This was a routine conversion of deferred/phantom stock with shares withheld for taxes (similar to a cashless settlement), not an open‑market sale or purchase. Such withholding transactions are common for vested awards and do not necessarily signal the insider’s market view.
