Management Commentary and Plan Structure: The bonus plan ties executive compensation to specific performance targets. The Compensation Committee will establish specific Target and Maximum levels for each metric. Payment is calculated via linear interpolation if performance falls between these levels. Each individual metric must be met at the Target Level to credit the associated percentage toward the bonus pool.

- CEO: 60.0% (Target) to 90.0% (Maximum) of salary.
- CFO, COO, Chief Commercial Banking Officer: 40.0% (Target) to 60.0% (Maximum) of salary.
- Chief Human Resources Officer: 35.0% (Target) to 52.5% (Maximum) of salary.

The maximum pool amount is subject to adjustment for new hires, salary adjustments, or if an officer becomes ineligible before December 31, 2026.
