        <footnote id="F1">On February 6, 2019, Ms. Petersen was granted 10,000 performance units (the &quot;Performance Units&quot;) pursuant to the IES Holdings, Inc. 2006 Equity Incentive Plan, as amended and restated (the &quot;2006 Equity Incentive Plan&quot;). Each Performance Unit represented a contractual right in respect of one share of the Issuer's common stock. The Performance Units vested, if at all, in three tranches upon the achievement of certain specified annual financial performance objectives and the continued performance of services through the applicable scheduled vesting date. On December 3, 2021, upon the filing of the Company's Annual Report on Form 10-K for its fiscal year ended September 30, 2021, the performance and service criteria for the third tranche of Performance Units was determined to have been fully met, resulting investing of 5,999.9 Performance Units under this award.</footnote>
