        <footnote id="F1">Each deferred stock unit represents a contingent right to receive one share of PDM common stock. Deferred stock units may be settled in cash or common stock at PDM's election.</footnote>
        <footnote id="F2">On February 20, 2024, the reporting person was granted 22,901 deferred stock units, vesting in four equal, annual installments beginning on the anniversary of the grant date. On February 20, 2026, the second 25% of the grant vested (5,725 shares) and were settled in PDM common stock. In connection with this vesting, 2,436 shares were forfeited by the employee and delivered to PDM to satisfy tax withholding obligations.</footnote>
