        <footnote id="F1">The account under the 2005 NQ Plan (as defined below) tracks Worthington Industries, Inc. common shares on a one-for-one basis.</footnote>
        <footnote id="F2">Prior to October 1, 2014, the account balances related to the theoretical Worthington Industries, Inc. common share deemed investment option could be immediately transferred to other deemed investment options under the terms of the Worthington Industries, Inc. Amended and Restated 2005 Deferred Compensation Plan, as amended (the &quot;2005 NQ Plan&quot;). The 2005 NQ Plan provides that effective October 1, 2014 and thereafter, any amount credited in a participant's account to the phantom stock fund (i.e. the theoretical Worthington Industries, Inc. common share deemed investment option) may not be transferred to an alternative deemed investment option under the 2005 NQ Plan until distribution from the 2005 NQ Plan.  Distributions are made only in common shares of Worthington Industries, Inc. and generally commence upon leaving Worthington Industries, Inc. and its subsidiaries.</footnote>
        <footnote id="F3">The amount reported includes the additional unfunded theoretical common shares (i.e., phantom stock) credited to the theoretical Worthington Industries, Inc. common share deemed investment option pursuant to the dividend reinvestment feature of the 2005 NQ Plan on March 29, 2023.</footnote>
