% or below. There will be no payout of comparative ROE if CET1 ratio is below 10%. The Company’s relative TSR has been compared to the KBW NASDAQ Bank Index since 2022. At the end of the performance period, the Company’s actual performance against the performance targets will be computed separately, then added together to obtain the total number of shares awarded. The Compensation Committee approved the following performance targets for the 2024-2026 performance period: Cumulative ROE (75%):

| PSU Vesting 
 (%)         |     | 3 year arithmetic mean of 
 ROE of sorted peer        
 (percentile)              |       |
| —%          |     |                           | <25th |
| 50%         |     |                           | 25th  |
| 100%        |     |                           | 50th  |
| 200%        |     |                           | >75th |

CET1 Ratio Governor: Also included in the determination of the Company's PSU payout is a factor for the Company's CET1 Ratio (defined as Total Ending Common Equity Tier 1 Capital divided by Total Ending Risk Weighted Assets). The CET1 Ratio will be calculated as the 12‐period arithmetic mean of the CET1 Ratio as of the end of each quarter within the stated plan performance period (i.e., Q1 2024 – Q4 2026).

| PSU Payout on ROE Performance                            |     | CET1 Ratio         
 12 quarter average |                 |
| 0%                                                       |     |                    | ≤10%            |
| Results will be adjusted proportionate to the % decrease |     |                    | >10.0% - 10.99% |
| Based solely on the results of relative ROE              |     |                    | ≥11%            |

The Company will interpolate on a straight-line basis between the threshold, target and maximum in each category of performance.
