Mead Christopher E 4

What Happened

• Christopher E. Mead, Vice President of Arthur J. Gallagher & Co., had 5,258 performance-based units vest on March 15, 2026 and converted/received 5,258 shares (acquired at $0 as these were awards).
• To cover the tax liability from the vesting, 2,019 shares were withheld/disposed on 2026-03-15 for $419,811 and another 432 shares were withheld/disposed on 2026-03-16 for $89,826 — total tax withholding = $509,637.
• Transaction codes: A = award/grant (vesting), M = exercise/conversion of derivative into shares, F = shares disposed to satisfy tax obligations. This was a vesting/tax-withholding event, not an open-market purchase or voluntary sale.

Key Details

• Transaction dates: March 15, 2026 (vesting/conversion and initial withholding) and March 16, 2026 (additional tax withholding).
• Prices shown: shares acquired at $0 (award conversion); withheld shares valued at $207.93 each for withholding calculations.
• Withheld/disposed shares: 2,451 total (2,019 + 432) to satisfy taxes; total withholding value ≈ $509,637.
• Shares owned after transaction: not specified in the provided filing details.
• Relevant footnotes: F1 (performance share units awarded 3/15/2023 earned and vested 3/15/2026), F2 (shares withheld to cover tax obligations related to vesting). No late filing indicated.

Context

• This was a vesting and conversion of performance units, followed by a standard “sell/withhold to cover taxes” action — effectively a cashless-withholding, not an open-market sale for investment purposes.
• Such transactions are routine when equity awards vest; they reflect compensation realization and tax withholding rather than a deliberate buy or sell signal by the insider.
