        <footnote id="F1">A previously reported restricted stock unit award granted on May 10, 2022 vested on May 10, 2025 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 9, 2025 was not less than the closing price on May 10, 2022 and (ii) MannKind's total shareholder return (TSR) over the period from May 10, 2022 to May 10, 2025 was at the 73.9th 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 196% of target, resulting in a total share delivery of 215,600 shares. The acquisition of 110,000 shares pursuant to the restricted stock award was reported in Table I of the Form 4 filed by the Reporting Person on May 12, 2022.</footnote>
