(1) | Compensation Actually Paid (“CAP”) amounts include total compensation as reported in the Summary Compensation Table, less the grant date fair value of stock awards (RSA), plus the change in fair value of equity awards during the reported year. A reconciliation of CAP to total compensation as reported in the Summary Compensation Table is shown in the table below.
| (2) | William (“Billy”) Carroll, Jr. was the PEO for each of 2024, 2023, 2022, 2021 and 2020. The non-PEO NEOs for 2024 and 2023 are Wesley M. Welborn, Ronald J. Gorczynski, Rhett D. Jordan and Cynthia A. Cain, for 2022 are Wesley M. Welborn, Ronald J. Gorczynski, Gregory L. Davis and Rhett D. Jordan and for 2021 and 2020, Wesley M. Welborn and Ronald J. Gorczynski.
| (3) | Peer group total shareholder return reflects the S&P SmallCap Bank Index, which is a market-capitalization-weighted index that tracks the performance of NYSE and NASDAQ-listed banks, insurance underwriters and specialty lenders in S&P's coverage universe with $250 million to $1 billion market capitalization as of most recent pricing data. The S&P SmallCap Bank Index is the same index used for our performance graph disclosed in our Annual Report on Form 10-K for the year ended December 31, 2024.
| (4) | We selected operating net income, which is a non-GAAP measure, as the most important performance measurement for 2024. Operating net income is calculated by excluding the following from net income: securities gains and losses, merger related and restructuring expenses and other noncore operating items.

Compensation Actually Paid vs. Total Shareholder Return | Relationship Between PEO and Average Non-PEO NEOs Compensation Actually Paid and Total Shareholder Return (“TSR”) The following chart sets forth the relationship between Compensation Actually Paid to our PEO, the average of Compensation Actually Paid to our other NEOs. In addition, the graph compares our cumulative TSR and our S&P SmallCap Bank Index cumulative TSR for the indicated years. The cumulative TSR assumes an initial investment of $100 at the market close on December 31, 2019, in SMBK common stock and in the common stock of companies within our SmallCap Bank Index group. A $100 investment in SMBK stock on December 31, 2019, would be valued at $139.02 at December 31, 2024, which outperformed the TSR of a $100 investment in our SmallCap Bank Index, which would be valued at $132.44, invested over the same time period. |  |  |  |
Compensation Actually Paid vs. Net Income | Relationship Between PEO and Average Non-PEO NEOs Compensation Actually Paid and Net Income The following chart sets forth the relationship between Compensation Actually Paid to our PEOs, the average of Compensation Actually Paid to our other NEOs, and our Net Income each of the four most recently completed fiscal years. |  |  |  |
Compensation Actually Paid vs. Company Selected Measure | Relationship Between PEO and Average Non-PEO NEOs Compensation Actually Paid and Operating Net Income The following chart sets forth the relationship between Compensation Actually Paid to our PEOs, the average of Compensation Actually Paid to our other NEOs, and our operating net income during the four most recently completed fiscal years. |  |  |  |
