        <footnote id="F1">On February 6, 2019, Ms. McLauchlin was granted 41,667 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 represents a contractual right in respect of one share of the Issuer's common stock.

On December 7, 2020, upon the filing of the Company's Annual Report on Form 10-K for its fiscal year ended September 30, 2020, the performance and service criteria for the second tranche of Performance Units was determined to have been fully met, resulting investing of 11,979 Performance Units under this award.</footnote>
