Mississippi River Bank will continue to operate under its existing branding as a division of MNMB’s wholly-owned bank subsidiary, Merchants & Marine Bank. Longtime Mississippi River Bank Chief Executive Officer Mike Bush and President / Chief Operations Officer Lisa Works will remain with the Company and will continue to lead the Mississippi River Bank division in their existing roles.

“We are delighted to welcome Mississippi River Bank to our growing family of community banking brands,” commented Clayton Legear, Chief Executive Officer of MNMB and Merchants & Marine Bank. “The tradition of top-level financial performance established by Mississippi River Bank’s leadership, paired with their stellar record of service make them an exciting addition to our Company. We look forward to working with Mike, Lisa and the entire Mississippi River Bank team to continue serving Plaquemines Parish and the West Bank for decades to come.”

The acquisition, which is subject to customary closing conditions including the approval of Mississippi River Bank’s shareholders and the receipt of all necessary regulatory approvals, is expected to be completed during the first quarter of 2024. Both Merchants & Marine Bank and Mississippi River Bank have earned the coveted 5-Star Rating by national rating firm Bauer Financial based on their financial performance.

"The Merchants & Marine Bancorp team understands the value of our history, our approach, and our commitment to our communities. We're moving into the future together, doing what we do best."
