        <footnote id="F1">This amendment is being filed to reverse the previously reported grant to the reporting person of 6,200 restricted stock units under the Silgan Holdings Inc. Amended and Restated 2004 Stock Incentive Plan (the &quot;Plan&quot;). The Issuer's Compensation Committee has rescinded such grant and its approval of such grant as such grant was approved after the Plan had expired on December 31, 2022, and the reporting person has no rights to such grant.</footnote>
        <footnote id="F2">This amount includes 71,120 restricted stock units that are not yet vested that have been granted under the Plan prior to its expiration. Upon vesting, these restricted stock units will be settled in shares of Common Stock on a 1-for-1 basis.</footnote>
