<p style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; font-variant: normal; text-align: justify; margin: 0pt; text-indent: 36pt;">On May 13, 2022, Mercantile Bank Corporation (the &#8220;Company&#8221;) announced that Michael H. Price will be stepping down as a member of the Audit, Governance and Nominating, and Compensation Committees of Mercantile Bank Corporation and its wholly owned subsidiary Mercantile Bank. Mr. Price will also be replaced as Executive Session Facilitator by Director Michael Davenport. Mr. Price will continue to serve as Chairman of the Board.</p>

<p style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; font-variant: normal; text-align: justify; margin: 0pt; text-indent: 36pt;">Robert B. Kaminski, Jr., President and Chief Executive Officer of Mercantile, commented &#8220;we have had the opportunity to connect over the past few days with several of our institutional shareholders and while we believe that Mr. Price is independent under NASDAQ and SEC rules and is a valuable member of our Board Committees, we are sensitive to the policies of our shareholders against a former company CEO maintaining membership on these committees, and value their input. As such, Mr. Price has agreed to step down from committee service and as the Executive Session Facilitator, effective immediately.&#8221; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</p>
