        <footnote id="F1">On January 17, 2019, the reporting person was granted 75,780 performance units eligible to vest at target levels of performance (with vesting of more or less units possible based on the performance)  of Pinnacle Financial Partners, Inc. (the &quot;Company&quot;) against certain performance metrics on an absolute basis for 2019 and 2022 and compared to peers for 2021 and so long as the ratio of Pinnacle Bank's nonperforming assets to its loans plus other real estate owned (&quot;NPA ratio&quot;) at December 31, 2023 was not greater than 3.00%. Based upon the Company's performance for 2019, 2020 and 2021 and the NPA ratio at December 31, 2023, as reflected in the Company's Annual Report on Form 10-K for 2023, the reporting person earned 50,098 performance units, which units vested and were settled in 50,098 shares of Company common stock. As described in footnote 3, a portion of those 50,098 shares of common stock were retained by the Company to cover withholding taxes owed by the reporting person.</footnote>
        <footnote id="F2">Performance units are settled in shares of common stock on a one-for-one basis. Accordingly, no purchase price was paid for the shares by the reporting person.</footnote>
