        <footnote id="F1">Represents long-term incentive performance (&quot;LTIP&quot;) units of Simon Property Group, L.P. (the &quot;Operating Partnership&quot;), of which Simon Property Group, Inc. (the &quot;Company&quot;) is the general partner, issued as long-term incentive compensation pursuant to the Operating Partnership's 2019 Stock Incentive Plan (the &quot;Plan&quot;), in compliance with Rule 16b-3. When earned and vested, each LTIP unit may be converted into a unit of limited partnership interest (&quot;Partnership Unit&quot;). Each Partnership Unit may be exchanged for a share of the Company's common stock, or cash, as selected by the Company.</footnote>
        <footnote id="F2">On March 11, 2022, the Reporting Person was awarded a maximum of 8,652 LTIP units, subject to certain performance conditions. On March 3, 2025, the Compensation and Human Capital Committee (the &quot;Compensation Committee&quot;) of the Board of Directors of the Company determined that the extent to which the performance measures had been achieved during the performance period resulted in 71.9%, or 6,225 of the LTIP units becoming earned LTIP units. The earned LTIP units vest on January 1, 2026, subject to a continued service requirement, or may vest earlier due to the Reporting Person's death or disability, a change of control of the Company, the retirement of the Reporting Person, subject to the approval of the Company's Compensation Committee, or as may otherwise be determined by the Company's Compensation Committee in accordance with the terms of the grant agreement and the Plan.</footnote>
        <footnote id="F3">Each Restricted Stock Unit (&quot;RSU&quot;) represents the contingent right to receive, at settlement, one share of common stock of the Company.</footnote>
        <footnote id="F4">The RSUs are being issued pursuant to the Plan, in compliance with Rule 16b-3. The RSUs will vest on March 3, 2028, subject to a continued service requirement, or may vest and settle earlier due the Reporting Person's death or disability, a change of control of the Company, the retirement of the Reporting Person, subject to the approval of the Company's Compensation Committee, or as may otherwise be determined by the Company's Compensation Committee in accordance with the terms of the grant agreement and the Plan. Vested RSUs will be settled in shares of the Company's common stock as soon as practicable after the vesting date.</footnote>
