        <footnote id="F1">On December 3, 2021, Mr. Simmes  was granted shares of time- and performance-based phantom stock units (&quot;PSUs&quot;) pursuant to the IES Holdings, Inc. 2006 Equity Incentive Plan, as amended and restated  (the &quot;2006 Equity Incentive Plan&quot;).   Each PSU represented a contractual right in respect of one share of the Issuer's Common Stock and would vest, if at all, upon the achievement of certain specified annual financial performance objectives and the continued performance of services through the scheduled vesting date.   On November 22, 2024, upon the filing of the Issuer's Annual Report on Form 10-K for its fiscal year ended September 30, 2024, the performance and service criteria were determined to have been met, resulting in the vesting of 13,740 time- and performance-based PSUs under this award.</footnote>
