Mercantile revenue rises as interest income and fees grow
Mercantile Bank Corporation’s third-quarter 2026 results showed net interest income of $60.9 million, up 17.1% from a year earlier. Noninterest income increased 18.4% to $12.3 million, supported by treasury management fees, interest rate swap income and mortgage banking income.
Treasury management fees rose approximately 28%, reflecting new commercial customers and existing clients’ expanded use of services. Eastern Michigan Bank contributed $5.8 million of net interest income and $0.5 million of noninterest income, meaning the reported revenue increase included contributions from the acquired business.

Cheaper funding offsets lower loan yields
Net interest margin widened to 3.73% from 3.49% in the third quarter of 2025. The improvement came even as the yield on loans declined to 6.12% from 6.35%, illustrating how lower funding costs can support a bank’s margin when lending yields weaken.
Mercantile’s cost of funds fell to 1.79% from 2.25%. The company cited lower rates on money market accounts and time deposits, a greater share of low-cost deposits, and reduced reliance on brokered deposits.
Local deposits grew $438 million during the first nine months of 2026, while brokered deposits declined $110 million. The loan-to-deposit ratio fell to 88.3% at September 30 from 91.2% at year-end 2025, giving the bank a larger deposit base relative to its outstanding loans.
Expense growth limits the profit gain
Net income reached $24.1 million, compared with $23.8 million a year earlier. Reported diluted earnings per share nevertheless declined to $1.39 from $1.46.
Noninterest expense increased to $43.6 million from $34.8 million. Eastern Michigan Bank accounted for $4.1 million of current-quarter expenses, while other increases included compensation, personnel investments, inflation and costs associated with a larger balance sheet. Federal income tax expense also rose, reaching $4.9 million from $3.7 million.
Adjusted diluted earnings were $1.42 per share, down from $1.50 a year earlier. This non-GAAP measure excludes acquisition and banking-system conversion costs and other one-time items; it supplements rather than replaces reported earnings.
Conclusion
Revenue growth outpaced profit growth as higher operating costs and taxes absorbed much of the improvement. The next scheduled operational milestone is Mercantile’s core and digital banking system conversion, which management expects in the first quarter of 2027.
