GALLAGHER THOMAS JOSEPH 4

What Happened

• Thomas Joseph Gallagher, President of Arthur J. Gallagher & Co. (AJG), exercised/converted a derivative position on March 31, 2026 that resulted in 76.382 shares being acquired at an implied price of $215.95 per share (total value ≈ $16,495). The company withheld the same 76.382 shares to satisfy employment tax withholding obligations related to the vesting/conversion; no open-market sale was reported.

Key Details

• Transaction date: 2026-03-31; Form 4 filed 2026-04-02 (timely).
• Exercise/conversion (code M): 76.382 shares @ $215.95 — acquired; total ≈ $16,495.
• Tax withholding (code F): 76.382 shares @ $215.95 — withheld/disposed to cover taxes; total ≈ $16,495.
• A separate line shows the derivative converted/removed (reported as disposed @ $0) reflecting the conversion of the derivative into stock.
• Shares owned after transaction: not specified in this filing.
• Notable footnotes/remark: filing disclaims beneficial ownership of the shares (F1); transaction relates solely to withholding of shares to cover employment taxes with respect to vesting under the Age 62 Plan.

Context

• This was a routine conversion/withholding event rather than an open-market sale or purchase. The equal numbers acquired and withheld indicate a cashless/tax-withholding settlement tied to vested awards, which is common for executive deferred-compensation or option exercises and does not necessarily signal a change in insider sentiment.
