        <footnote id="F1">On March 31, 2024, (i) 310 restricted stock units vested as the third installment of the time-based award granted in March 2021, for which the Federal Agricultural Mortgage Corporation (&quot;Farmer Mac&quot;) retained 149 shares to satisfy withholding requirements, (ii) 483 performance-based restricted stock units vested that were granted in March 2021 (465 target units vesting at a 103.7754% performance factor), for which Farmer Mac retained 232 shares to satisfy withholding requirements, (iii) 224 restricted stock units vested as the second installment of the time-based award granted in March 2022, for which Farmer Mac retained 108 shares to satisfy withholding requirements, and (iv) 212 restricted stock units vested as the first installment of the time-based award granted in March 2023, for which Farmer Mac retained 102 shares to satisfy withholding requirements.</footnote>
        <footnote id="F2">In accordance with a policy adopted by the Human Capital and Compensation Committee of Farmer Mac's Board of Directors, the price used for the calculation of the number of shares withheld by Farmer
Mac in satisfaction of tax liability is the closing price of Farmer Mac's Class C Non-Voting Common Stock on the New York Stock Exchange on the last trading day before the vesting date.</footnote>
        <footnote id="F3">Includes 2,071 unvested restricted stock units previously granted pursuant to Farmer Mac's Amended and Restated 2008 Omnibus Incentive Plan. The grants of restricted stock units have been described in
detail in Farmer Mac's prior filings with the Securities and Exchange Commission. The total amount of securities beneficially owned has been adjusted since the Reporting Person's last filing to reflect 18 more shares that vested on March 31, 2024 as a result of applying a 103.7754% performance factor to 465 target restricted stock units granted in March 2021.</footnote>
