Jackson Matthew A 4

What Happened

• Matthew A. Jackson, SVP and Assistant Treasurer of Simon Property Group (SPG), received a grant/vesting of 1,361 restricted shares on 2026-04-01. To satisfy tax withholding obligations related to the vesting, 447 of those shares were withheld (disposed) at an indicated value of $186.53 per share, totaling about $83,379. Net new shares issued to him from this vesting = 1,361 - 447 = 914 shares.
• This was an award/vesting event (code A) with a related withholding for taxes (code F), not an open-market sale or purchase.

Key Details

• Transaction date: 2026-04-01; Form 4 filed 2026-04-02 (filed the next day, timely).
• Award: 1,361 restricted shares (price N/A for awards).
• Withheld: 447 shares at $186.53 per share → $83,379 withheld to cover taxes.
• Net shares retained from vesting: 914 shares.
• Footnotes: F1 — restricted stock award under the 2019 Stock Incentive Plan and subject to forfeiture until vesting requirements are met. F2 — 447-share withholding represents tax obligations in connection with the vesting.
• Transaction codes: A = Award/Grant; F = Tax withholding (not a market sale).

Context

• This is a routine vesting and tax-withholding event. The withholding is a common way to satisfy tax liabilities when restricted stock vests and does not indicate an active decision to sell shares in the open market.
• For retail investors, award vesting increases insider ownership when shares are retained; here Jackson retained 914 shares after withholding.
