        <footnote id="F1">A previously reported restricted stock unit award granted on May 18, 2021 vested on May 17, 2024 upon the achievement of performance objectives established by MannKind's compensation committee at the time of the approval of the award. Specifically, (i) the closing price of MannKind's common stock on May 17, 2024 was not less than the closing price on May 17, 2021 and (ii) MannKind's total shareholder return (TSR) over the period from May 18, 2021 to May 17, 2024 was at the 74.5th percentile of the TSR of the Russell 3000 Pharmaceutical &amp; Biotechnology Index over the same period. As a result, the performance objective was achieved at 198% of target, resulting in a total share delivery of 156,420 shares.
