Adoption of Bonus Plan
On March 19, 2026, the Boards of Directors of Mercantile Bank Corporation (“Mercantile”), and of Mercantile’s wholly-owned subsidiary, Mercantile Bank (the “Bank”), adopted an executive officer bonus plan for 2026 (the “Executive Officer Plan”).
The Executive Officer Plan provides for cash bonuses for Raymond E. Reitsma, President and Chief Executive Officer of the Bank and Mercantile; Charles E. Christmas, the Executive Vice President, Chief Financial Officer, and Treasurer of Mercantile, and the Executive Vice President and Chief Financial Officer of the Bank; Mark S. Augustyn, the Executive Vice President and Chief Commercial Banking Officer of the Bank; Scott P. Setlock, the Executive Vice President, Chief Operating Officer and Secretary of the Bank and Mercantile; Brett E. Hoover, the Executive Vice President and Chief Human Resource Officer of the Bank; and one other member of the Bank's executive team.
Payment from the bonus pool under the Executive Officer Plan is based on the achievement of targets under the following 2026 bonus metrics. The specific targets for each metric will be established by the Compensation Committee of Mercantile’s Board of Directors. The Compensation Committee will establish a target level of performance for each metric (the “Target Level”) and a maximum level of performance for each metric (the “Maximum Level”). If Mercantile’s performance on a metric is at the Target Level, the percentage associated with that metric which will be credited toward the calculation of the bonus pool will be at the Target Percentage shown in the chart below. If Mercantile’s performance on a metric is at or above the Maximum Level, the percentage associated with that metric which will be credited toward the calculation of the bonus pool will be at the Maximum Percentage shown in the chart below. A linear interpolation would be used to determine the percentage assigned to that metric in the event that Mercantile’s performance falls between the Target Level and the Maximum Level.

18.75% |
The amount that will be allocated to the bonus pool under the Executive Officer Plan will depend on Mercantile’s performance on each of the 2026 bonus metrics. If performance on each bonus metric is at the Target Level, the amount allocated to the bonus pool will be $1,206,725 (the “Target Bonus Pool”). The amount allocated to the bonus pool will be increased if performance on one or more bonus metrics exceeds the Target Level, but will not be greater than 150% of the Target Bonus Pool or $1,810,087 (the “Maximum Bonus Pool”). A linear interpolation would be used to determine the amount allocated to the bonus pool in the event that performance on one or more metrics falls between the Target Level and the Maximum Level.
The maximum amount will be appropriately adjusted if (a) a newly hired employee becomes a named executive officer (as defined in Item 402(a)(3) of SEC Regulation S-K) or a designated member of the executive management team and becomes eligible to participate in the Executive Officer Plan, (b) an executive officer's base salary is adjusted during the year, or (c) an executive officer becomes ineligible before December 31, 2026.
Each individual target must be met at the Target Level in order for the percentage associated with that metric to be credited toward payment from the bonus pool. The accumulated percentage for each individual target attained will be applied to the bonus pool to determine the total amount of the bonus pool to be awarded (the “Award Amount”). For example, if the first four factors are attained at the Target Level and the next two factors are not attained, the Award Amount under this Plan would be $1,206,725 x 75.0% = $905,044. As another example, if the first three factors are attained at the Maximum Level and the next three factors are attained at the Target Level, the Award Amount under this Plan would be $1,206,725 x 131.25% = $1,583,827.
The Award Amount will be paid to each executive officer pro rata based on a uniform percentage of the executive officer's 2026 salary, not to exceed:
| |
Target Percentage |
Maximum Percentage |
| Chief Executive Officer |
60.0% |
90.0% |
| Chief Financial Officer |
40.0% |
60.0% |
| Chief Operating Officer |

60.0% |
| Chief Commercial Banking Officer |
40.0% |
60.0% |
| Chief Human Resources Officer |
35.0% |
52.5% |
The “target percentage” of salary in the chart above will be adjusted downward if Mercantile does not satisfy each bonus metric at the Target Level. A linear interpolation will be used to determine the percentage of salary to be paid if Company performance on one or more metrics falls between the Target Level and the Maximum Level.
Any bonus awards that are earned under the plan will be paid to the executive officers on or before March 15, 2027.
Payments under the plan are subject to specified conditions, qualifications, and clawback provisions. The plan, to the extent provided for in the plan, may be amended by the Compensation Committee of Mercantile's Board of Directors.
A copy of the Executive Officer Plan is attached as Exhibit 10.1.
