**Mercantile Bank Corporation Announces Strong Third Quarter 2025 Results**

*Growth in net interest income and certain noninterest income categories and continued strength in asset quality metrics and capital measures highlight the quarter*

**GRAND RAPIDS, Mich., October 21, 2025** – Mercantile Bank Corporation (NASDAQ: MBWM) ("Mercantile") reported net income of $23.8 million, or $1.46 per diluted share, for the third quarter of 2025, compared with net income of $19.6 million, or $1.22 per diluted share, for the third quarter of 2024. Net income during the first nine months of 2025 totaled $65.9 million, or $4.06 per diluted share, compared with net income of $60.0 million, or $3.72 per diluted share, during the first nine months of 2024.

"We are very pleased to report another quarter of robust financial performance, especially when taking into consideration the lengthy and ongoing period of uncertain macro-economic conditions," said Ray Reitsma, President and Chief Executive Officer of Mercantile. "Our strong operating results reflected net interest income expansion, a stable and healthy net interest margin, solid growth in certain core noninterest income categories, a notable decline in federal income tax expense, strong local deposit growth, and continuing strength in asset quality metrics and capital measures. The growth in local deposits provided for a reduction in our loan-to-deposit ratio, the lowering of which remains an important strategic goal."

Third quarter highlights include:

● Return on average assets of 1.50 percent and return on average equity of 14.72 percent

● Tangible book value per common share of $37.41 as of September 30, 2025, up $4.27, or approximately 13 percent, since year-end 2024

● Net interest income expansion of nearly 8 percent

● Noteworthy increases in treasury management and payroll services fees of approximately 11 percent and 16 percent, respectively

● Significant decrease in effective tax rate from approximately 20 percent in the third quarter of 2024 to approximately 13 percent in the third quarter of 2025 due to the acquisition of transferable energy tax credits and net benefits from investments in tax credit structures

● Solid commercial loan pipeline

● Ongoing low levels of nonperforming assets, past due loans, and loan charge-offs

● Notable reduction in loan-to-deposit ratio from 102 percent as of September 30, 2024, to 96 percent as of September 30, 2025, largely reflecting robust local deposit grwoth

● Strong tangible and regulatory capital positions

● Announced planned partnership with Eastern Michigan Financial Corporation

------

**Operating Results**

Net revenue, consisting of net interest income and noninterest income, was $62.4 million during the third quarter of 2025, up $4.4 million, or 7.6 percent, from $58.0 million during the prior-year third quarter. Net interest income during the current-year third quarter was $52.0 million, up $3.7 million, or 7.7 percent, from $48.3 million during the respective 2024 period as growth in earning assets more than offset a slightly lower net interest margin. Noninterest income totaled $10.4 million during the third quarter of 2025, compared to $9.7 million during the third quarter of 2024. The increase primarily reflected higher levels of treasury management and payroll services fees and earnings on bank owned life insurance.

The net interest margin was 3.50 percent in the third quarter of 2025, down marginally from 3.52 percent in the prior-year third quarter. The yield on average earning assets was 5.75 percent during the current-year third quarter, a decrease from 6.08 percent during the respective 2024 period. The lower yield mainly stemmed from a reduced yield on loans and a change in earning asset mix, which more than offset an improved yield on securities resulting from the reinvestment of relatively low-yielding bonds and portfolio expansion activities. The yield on loans was 6.38 percent during the third quarter of 2025, down from 6.69 percent during the third quarter of 2024, primarily due to lower interest rates on variable-rate commercial loans resulting from the Federal Open Market Committee ("FOMC") lowering the targeted federal funds rate. The FOMC decreased the targeted federal funds rate by 50 basis points in September of 2024 and 25 basis points in each of November and December of 2024, during which time average variable-rate commercial loans represented approximately 73 percent of average total commercial loans. A further 25 basis point reduction in the targeted federal funds, which was approved by the FOMC in September of 2025, also contributed to the reduced loan yield. Signifying the success of a strategic initiative to lower the loan-to-deposit ratio and increase on-balance sheet liquidity, higher-yielding loans represented a decreased percentage of earning assets and lower-yielding securities accounted for an increased percentage of earning assets in the third quarter of 2025 compared to the third quarter of 2024.

During the third quarter of 2025, the cost of funds was 2.25 percent, down from 2.56 percent in the third quarter of 2024, mainly due to lower rates paid on money market accounts and time deposits, reflecting the decreased interest rate environment that began in September of 2024 in conjunction with the FOMC's lowering of the targeted federal funds rate.

Mercantile recorded provisions for credit losses of $0.2 million and $1.1 million during the third quarters of 2025 and 2024, respectively. The provision expense recorded during the current-year third quarter mainly reflected a $3.1 million increase in the specific allocation for a commercial construction loan relationship that was placed on nonaccrual during the second quarter of 2025 and a $0.9 million net increase in qualitative factor allocations resulting from changes in the composition of the loan portfolio; the impacts of these factors were partially offset by faster residential mortgage and consumer loan prepayment speeds and the associated shortened average lives of the portfolios and a net decline in the loan portfolio. The provision expense recorded during the third quarter of 2024 primarily reflected an increase in qualitative factor allocations and allocations necessitated by net loan growth, which were partially offset by decreases in the calculated allowance stemming from the payoffs of two larger problem commercial lending relationships. The recording of net loan recoveries and sustained strength in loan quality metrics during both periods positively impacted necessary provision levels.

------

Noninterest income totaled $10.4 million during the third quarter of 2025, up $0.7 million, or 7.5 percent, from $9.7 million during the respective 2024 period, mainly due to growth in treasury management fees and payroll services fees of approximately 11 percent and 16 percent, respectively, which more than offset a reduction in mortgage banking income. The lower level of mortgage banking income primarily resulted from a change in the quarter-end fair value of commitments to originate salable residential mortgage loans. Noninterest income during the third quarter of 2025 also included bank owned life insurance claims totaling $0.3 million.

Noninterest expense totaled $34.8 million during the third quarter of 2025, up from $32.3 million during the prior-year third quarter. The increase mainly resulted from higher salary and benefit costs, primarily reflecting annual merit pay increases, market adjustments, and lower residential mortgage loan deferred salary costs, which more than offset a lower bonus accrual and reduced health insurance claims. Acquisition costs related to Mercantile's previously announced partnership with Eastern Michigan Bank Corporation, along with increased data processing costs, contributions to The Mercantile Bank Foundation, and allocations to the reserve for unfunded loan commitments, largely resulting from an increase in commercial loan commitments, also contributed to the rise in noninterest expense.

Federal income tax expense was $3.7 million during the third quarter of 2025, compared to $4.9 million during the respective 2024 period. The acquisition of transferable energy tax credits and the net benefits from investments in tax credit structures during the third quarter of 2025 provided for aggregate tax benefits of $1.0 million and $0.7 million, respectively, during the period. The recording of the tax benefits positively impacted Mercantile's effective tax rate, which equaled 13.4 percent during the current-year third quarter, down from 20.1 percent during the third quarter of 2024.

Mr. Reitsma commented, "Our net interest margin has remained strong and relatively steady over the past five quarters, with ongoing growth in earning assets providing for net interest income expansion. We are pleased with the higher levels of treasury management and payroll services fees, mainly reflecting customers' increased use of products and services and effective marketing efforts, and noteworthy decrease in federal income tax expense, primarily resulting from the acquisition of transferable energy tax credits and net benefits from investments in tax credit structures. Growing our balance sheet in a cost-effective manner while continuing to deliver outstanding service and offer market-leading products and services to our customers remain important objectives."

**Balance Sheet**

As of September 30, 2025, total assets were $6.31 billion, up $256 million from December 31, 2024. Total loans increased $14.4 million during the first nine months of 2025, primarily reflecting net growth in commercial loans of $43.0 million. Commercial loans grew an annualized 1.6 percent during the nine months ended September 30, 2025, despite the full payoffs and partial paydowns of certain larger relationships, which aggregated $255 million during the period, including $101 million during the third quarter. The payoffs and paydowns stemmed from sales of assets and customers using excess cash flows generated within their operations to make line of credit reductions. Commercial loan originations, consisting of loans to new clients and expansions of existing credit relationships, remained solid across all segments during the third quarter of 2025.

Residential mortgage loans declined $46.7 million, and other consumer loans were up $18.1 million during the first nine months of 2025. During the first nine months of 2025, securities available for sale grew $125 million, and interest-earning deposits increased $82.4 million.

------

As of September 30, 2025, unfunded commitments on commercial construction and development loans, which are expected to be funded over the next 12 to 18 months, and residential construction loans, which are expected to be largely funded over the next 12 months, totaled $216 million and $37.0 million, respectively. As of September 30, 2024, unfunded commitments on commercial construction and development loans and residential construction loans totaled $241 million and $34.0 million, respectively.

Commercial and industrial loans and owner-occupied commercial real estate loans combined represented approximately 55 percent of total commercial loans as of September 30, 2025, a level that has remained relatively consistent with prior periods and in line with our expectations.

Total deposits equaled $4.81 billion as of September 30, 2025, compared to $4.70 billion as of December 31, 2024. Local deposits were up $84.2 million, or 1.9 percent, during the first nine months of 2025, while brokered deposits increased $29.2 million during the respective period. The increase in local deposits reflected net growth in various existing deposit relationships and successful client acquisition efforts, which more than offset the typical level of seasonal deposit withdrawals by customers to make bonus and tax payments and partnership distributions. The loan-to-deposit ratio declined from 98 percent as of year-end 2024 to 96 percent as of September 30, 2025, largely reflecting the increase in local deposits and expansion of the securities portfolio. The loan-to-deposit ratio equaled 102 percent as of September 30, 2024. Wholesale funds were $525 million and $537 million at September 30, 2025, and December 31, 2024, respectively, with both amounts representing approximately 10 percent of total funds at the end of each period. Noninterest-bearing checking accounts represented approximately 25 percent of total deposits as of September 30, 2025.

Mr. Reitsma noted, "While being overshadowed by the elevated levels of line paydowns and full payoffs, commercial loan originations remained strong during the third quarter of 2025. Based on our current pipeline and ongoing discussions with existing and prospective borrowers, we believe plentiful opportunities to originate commercial loans will exist in future periods. We are pleased with the growth in local deposits and associated decline in our loan-to-deposit ratio during the third quarter of 2025 and will continue our efforts to fund loan originations and investment purchases through local deposit generation."

**Asset Quality**

Nonperforming assets totaled $9.8 million, or 0.2 percent of total assets, as of September 30, 2025, compared to $5.7 million, or less than 0.1 percent of total assets, as of December 31, 2024, and $9.9 million, or 0.2 percent of total assets, as of September 30, 2024. The increase in nonperforming assets during the first nine months of 2025 mainly reflected the weakening of the previously mentioned nonperforming commercial construction loan, which accounted for approximately 56 percent of total nonperforming assets as of September 30, 2025, and necessitated specific reserve allocations totaling $5.5 million during the second quarter and third quarter of 2025. The level of past due loans remains nominal. During the first nine months of 2025, loan charge-offs were $0.3 million, while recoveries of prior period loan charge-offs totaled $1.1 million, providing for net loan recoveries of $0.8 million, or an annualized 0.02 percent of average total loans.

Mr. Reitsma remarked, "As reflected by continuing low levels of nonperforming assets, past due loans, and loan charge-offs, the quality of our asset base remained robust during the third quarter of 2025. We remain committed to underwriting loans across all portfolio segments in a disciplined manner, including adherence to internal policy guidelines, and detecting any weakening credit relationships and developing systemic or sector-specific credit issues as soon as possible to minimize the impact of such on our overall financial health. Our borrowers have continued to perform well during the prolonged period of uncertain macro-economic conditions."

------

**Capital Position** 

Shareholders' equity totaled $658 million as of September 30, 2025, up $73.1 million from December 31, 2024. Mercantile Bank maintained "well-capitalized" positions at the end of the third quarter of 2025 and year-end 2024, with total risk-based capital ratios of 14.3 percent and 13.9 percent, respectively. As of September 30, 2025, Mercantile Bank had approximately $236 million in excess of the 10 percent minimum regulatory threshold required to be categorized as a "well-capitalized" institution.

All of Mercantile Bank's investments are categorized as available-for-sale. As of September 30, 2025, the net unrealized loss on these investments totaled $36.1 million, resulting in an after-tax reduction to equity capital of $28.5 million. As of December 31, 2024, the net unrealized loss on these investments totaled $63.1 million, resulting in an after-tax reduction to equity capital of $49.8 million. Although unrealized gains and losses on investments are excluded from regulatory capital ratio calculations, Mercantile Bank's excess capital over the minimum regulatory requirement to be considered a "well-capitalized" institution would approximate $208 million on an adjusted basis as of September 30, 2025.

Mercantile reported 16,253,544 total shares outstanding as of September 30, 2025.

Mr. Reitsma concluded, "Our ongoing financial strength enabled us to continue our regular cash dividend program and once again provide shareholders with meaningful cash returns on their investments. We believe we are well positioned to effectively address any issues arising from the continuing uncertain macro-economic and operating conditions based on our sustained strength in capital levels, operating results, and asset quality metrics. Our deep focus on meeting clients' needs has played a significant role in our ability to retain existing relationships and secure new relationships, and we are confident that these inherent traits will provide us with abundant opportunities to book commercial loans and grow local deposits in future periods. We are excited about our planned partnership with Eastern Michigan Financial Corporation, which we believe will strengthen our Bank's standing as the largest bank founded, headquartered, and operated in the State of Michigan and assist us in meeting certain strategic goals, including enhancing our on-balance sheet liquidity and lowering our loan-to-deposit ratio."
