        <footnote id="F1">Reflects tax withholding in connection with the vesting and settlement of one-third of the Restricted Stock Units granted February 24, 2022.</footnote>
        <footnote id="F2">This Restricted Stock Unit (&quot;RSU&quot;) award was granted pursuant to The AES Corporation 2003 Long Term Compensation Plan and will generally vest in three annual installments, subject to the terms and conditions of the award. One-third of the RSUs will vest based on the reporting person's continued employment with AES or a subsidiary on each of February 24, 2024 and February 24, 2025. The final third of the RSUs will vest on February 24, 2026 subject to the reporting person's continued employment with AES or a subsidiary on such date and based, in part, on AES' achievement of certain environmental and social goals. Each RSU entitles the holder to one share of AES Common Stock.</footnote>
