Current report

This report contains certain non-GAAP financial measures, including adjusted net income, adjusted noninterest expense, and adjusted diluted earnings per share, each of which excludes after-tax costs associated with (i) Mercantile’s acquisition of Eastern Michigan Financial Corporation that was completed during the fourth quarter of 2025 ($0.2 million), and (ii) the previously announced core and digital banking system conversion ($2.3 million). These non-GAAP financial measures are identified in this report where they appear. We believe that presenting these non-GAAP financial measures provides investors, analysts, and other interested parties with meaningful supplementary information to assess Mecantile’s underlying operational performance by removing the effect of costs we consider to be non-recurring in nature and not reflective of Mercantile’s core operating results. These non-GAAP financial measures are used by management to evaluate Mercantile’s ongoing operations, for internal planning and forecasting purposes, and to assess period-over-period comparability. Management believes it is useful for the reader to review these non-GAAP adjusted measures alongside the GAAP measures. Our definition of these adjusted financial measures may differ from similarly named measures used by others. These non-GAAP measures have limitations as an analytical tool and should not be considered in isolation or as a substitute for our GAAP measures.

Current report

Core Deposit Intangible: In whole bank or bank branch acquisitions, the primary identifiable intangible asset recorded is the value of core deposit intangibles, representing the estimated value of long-term deposit relationships acquired. The determination involves assumptions and estimates, typically determined through discounted cash flow analysis, considering customer attrition/runoff, alternative funding costs, deposit servicing costs, and discount rates. Amortization of core deposit intangibles occurs over estimated useful lives reviewed periodically for reasonableness. These estimated useful lives, typically ranging from seven to 10 years with an accelerated rate of amortization, are periodically reviewed for reasonableness. Identifiable intangible assets, including core deposit intangibles, are assessed for impairment when events or changes suggest the carrying value may not be recoverable. Our policy dictates recognition of an impairment loss equal to the difference between the asset’s carrying amount and fair value if the expected undiscounted future cash flows are less than the carrying amount. Estimating future cash flows involves multiple estimates and assumptions, as previously mentioned.

Current report

On December 31, 2025, we consummated the acquisition of Eastern Michigan Financial Corporation and its wholly-owned banking subsidiary, Eastern Michigan Bank, headquartered in Crosswell, Michigan. Eastern Michigan Bank will operate alongside Mercantile Bank until the first quarter of 2027, at which time we plan to consolidate Eastern Michigan Bank into Mercantile Bank in conjunction with the completion of the conversion of our core operating system to a new provider. The first quarter of 2026 represented the initial period of financial performance that included Eastern Michigan Bank’s operating results.

Current report

We reported net income of $22.7 million, or $1.32 per diluted share, for the first quarter of 2026, compared with net income of $19.5 million, or $1.21 per diluted share, during the first quarter of 2025. Higher net interest income and noninterest income combined with lower provision expense more than offset increased noninterest costs.

Current report

Total deposits increased $135 million during the first three months of 2026. Aggregate net growth in almost all interest-bearing deposit types more than offset a decline of $50.4 million in out-of-area deposits and reductions in most business transaction deposit products from customers’ customary tax and bonus payments and partnership distributions during the early part of each first quarter. Securities sold under agreements to repurchase (“sweep accounts”) decreased $12.8 million and Federal Home Loan Bank of Indianapolis (“FHLBI”) advances declined $10.9 million during the first three months of 2026. Wholesale funds, comprised of out-of-area deposits and FHLBI advances, totaled $395 million, or about 7% of total funds, as of March 31, 2026, compared to $457 million, or approximately 8% of total funds, as of December 31, 2025.

Current report

Net interest income grew $7.4 million during the first three months of 2026 compared to the first quarter of 2025, reflecting the combined impact of a $5.1 million increase in interest income and a $2.3 million decrease in interest expense. Our net interest margin during the first quarter of 2026 was 8 basis points higher than during the first quarter of 2025, with our yield on earning assets declining 31 basis points and our cost of funds decreasing 39 basis points during that time period. The lower yield on earning assets largely reflected the aggregate 75 basis point reduction in the federal funds rate during the last four months of 2025, with the lower cost of funds being primarily attributed to the decline in the interest rate environment and the onboarding of Eastern Michigan Bank’s relatively low-cost deposit base. Also contributing to higher net interest income was growth in earning assets. Average earning assets during the first quarter of 2026 totaled $6.42 billion, compared to $5.70 billion during the first quarter of 2025.

Current report

We recorded a negative provision for credit losses of $1.8 million during the first three months of 2026, compared to a positive provision for credit losses of $2.1 million during the first quarter of 2025. The negative provision expense mainly reflected improvements to the economic forecast, changes in loan mix, a lower residential mortgage loan portfolio balance and a decline in specific allocations.

Current report

Noninterest income totaled $11.7 million during the first three months of 2026, compared to $8.7 million during the first quarter of 2025. We recorded improvements in virtually all noninterest income categories, including solid growth in treasury management fees, mortgage banking income, card income, interest rate swap income and payroll service fees. We also recorded $0.4 million in interest from the Internal Revenue Service on federal income tax payments made during 2024 that were subsequently refunded due to offsetting purchased energy tax credits.

Current report

Noninterest expense totaled $42.1 million during the first quarter of 2026, compared to $31.1 million during the first quarter of 2025. Excluding one-time costs aggregating $2.9 million related to the core and digital banking system conversion and $0.3 million associated with the acquisition of Eastern Michigan Financial Corporation, noninterest expense increased $7.8 million, or 25.0%, during the first three months of 2026 compared to the respective 2025 period using this non-GAAP measurement. The increase in noninterest expense mainly resulted from higher salary and benefit costs. A $1.2 million increase in allocations to the reserve for unfunded loan commitments, largely reflecting a significantly higher level of commercial loan commitments that have been accepted by customers, also contributed to the increase in noninterest expense. The remaining increase in noninterest expense largely reflects cost inflation and the increased cost of a larger balance sheet and branch network. Eastern Michigan Bank’s noninterest expense totaled $4.0 million during the first three months of 2026, including salary and benefit costs of $1.7 million, core deposit intangible asset amortization of $0.9 million, and data processing costs of $0.4 million.

Current report

Federal income tax expense was $4.6 million during the first three months of 2026, compared to $4.5 million during the first quarter of 2025. Federal income tax expense rose $0.1 million, while income before federal income tax expense increased $3.2 million. The acquisition of transferable energy tax credits and the benefits from low-income housing and historic tax credits provided for aggregate tax benefits of $0.8 million and $0.3 million during the first three months of 2026 and 2025, respectively. The effective tax rate was 16.9% and 18.8% during the first quarter of 2026 and 2025, respectively.

Current report

Total assets increased $110 million during the first three months of 2026, totaling $6.95 billion as of March 31, 2026. Interest-earning deposits increased $111 million and securities available for sale grew $23.2 million, while total loans declined $5.2 million during the first quarter of 2026. Deposits increased $135 million, while sweep accounts declined $12.8 million and FHLBI advances were down $10.9 million during the first three months of 2026.

Current report

Our loan portfolio has historically been primarily comprised of commercial loans. Commercial loans totaled $3.94 billion, or 81.7% of total loans, as of March 31, 2026. Commercial loans increased $16.7 million during the first three months of 2026, providing for an annualized growth rate of about 2%. As had been the case during most of 2025, commercial loan growth during the first quarter of 2026 was negatively impacted by a higher than typical level of payoffs and line of credit paydowns. Commercial loan payoffs, largely reflecting business sales, sales of assets and secondary market refinancings, and line of credit paydowns on larger commercial loan relationships totaled $180 million during the first three months of 2026, after aggregating $363 million, or an average of $91 million per quarter, in 2025. Our typical level of such payoffs and line paydowns average around $50 million per quarter.

Current report

Residential mortgage loans totaled $768 million, or 15.9% of total loans, as of March 31, 2026. Residential mortgage loans decreased $22.6 million during the first three months of 2026, as aggregate payoffs and scheduled monthly payments exceeded new loans added to the portfolio during the quarter. Residential mortgage loan originations totaled $128 million during the first quarter of 2026, reflecting an increase of over 27% compared to the first three months of 2025. Approximately 83% of the residential mortgage loans originated during the first quarter of 2026 were with the intent to sell, compared to about 80% during the first three months of 2026. Combined with increased prepayment speeds of our residential mortgage loan portfolio during the past two years, the increased percentage of loans sold has resulted in a declining portfolio balance. The increased volume of residential mortgage loans originated and percentage of loans sold has had a positive impact on mortgage banking income.

Current report

Total deposits increased $135 million during the first three months of 2026, totaling $5.42 billion as of March 31, 2026. Aggregate net growth in almost all interest-bearing deposit types more than offset a decline of $50.4 million in out-of-area deposits and reductions in most business transaction deposit products from customers’ customary tax and bonus payments and partnership distributions during the early part of each first quarter. Money market deposit accounts increased by $109 million, interest checking accounts were up $56.9 million, local time deposits grew $16.7 million, and savings deposits increased $10.3 million, while noninterest-bearing checking accounts declined $7.7 million during the first three months of 2026. The deposit balance increases reflect new deposit account relationships and additional funds from existing deposit customers, largely from business and public units.

Current report

We recorded a negative provision for credit losses of $1.8 million during the first quarter of 2026, compared to a positive provision for credit losses of $2.1 million during the first quarter of 2025. The negative provision expense recorded during the current-year first quarter mainly reflected improvements to the economic forecast, changes in loan mix, decreases to the residential mortgage loan portfolio, and a decline in specific allocations, which reduced the calculated allowance for credit losses by $0.6 million, $0.4 million, $0.2 million, and $0.2 million, respectively.

Current report

Noninterest income totaled $11.7 million during the first quarter of 2026, up $3.0 million, or 34.3%, from $8.7 million during the prior-year first quarter. The increase mainly reflected higher levels of treasury management fees, interest rate swap income, mortgage banking income, bank owned life insurance income, and payroll services fees. The increases in treasury management and payroll services fees primarily resulted from new commercial client acquisitions and effective marketing endeavors leading to customers’ amplified use of products and services, as well as a modified fee schedule. The growth in interest rate swap income mainly reflected a higher volume of new swap transactions, while the increase in mortgage banking income largely resulted from higher production and an increased percentage of loans originated with the intent to sell. Noninterest income during the first three months of 2026 included $0.4 million in interest from the Internal Revenue Service on federal income tax payments made during 2024 that were subsequently refunded due to offsetting purchased energy tax credits.

Current report

Noninterest expense totaled $42.1 million during the first quarter of 2026, compared to $31.1 million during the first quarter of 2025. Excluding one-time costs aggregating $2.9 million related to the core and digital banking system conversion and $0.3 million associated with the acquisition of Eastern Michigan Financial Corporation, noninterest expense increased $7.8 million, or 25.0%, during the first three months of 2026 compared to the respective 2025 period using this non-GAAP measurement. The increase in noninterest expense mainly resulted from higher salary and benefit costs, largely reflecting annual merit pay increases, market adjustments, a larger bonus accrual, increased health insurance costs, higher payroll taxes, larger residential mortgage lender commissions and incentives, lower residential mortgage loan deferred salary costs, and increased stock-based compensation costs. A $1.2 million increase in allocations to the reserve for unfunded loan commitments, largely reflecting a significantly higher level of commercial loan commitments that have been accepted by customers, also contributed to the increase in noninterest expense. The remaining increase in noninterest expense during the first three months of 2026 primarily reflected cost inflation and the increased cost of a larger balance sheet and branch network. Eastern Michigan Bank’s noninterest expense totaled $4.0 million during the first quarter of 2026, including salary and benefit costs of $1.7 million, core deposit intangible asset amortization of $0.9 million, and data processing costs of $0.4 million.

Current report

During the first quarter of 2026, we recorded income before federal income tax of $27.3 million and federal income tax expense of $4.6 million. During the first quarter of 2025, we recorded income before federal income tax of $24.0 million and federal income tax expense of $4.5 million. The $0.1 million increase in federal income tax expense primarily resulted from a higher level of income before federal income tax. The acquisition of transferable energy tax credits and the net benefits from low-income housing and historic tax credit investments provided for aggregate tax benefits of $0.8 million and $0.3 million during the first three months of 2026 and 2025, respectively. The recording of the tax benefits positively impacted our effective tax rate, which equaled 16.9% during the first quarter of 2026, down from 18.8% during the prior-year first quarter.

Previous report

We 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, during 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 to $60.0 million, or $3.72 per diluted share, during the first nine months of 2024. Growth in net income during both time frames reflected increased net interest income and noninterest income, lower provision expense and reduced federal income tax expense, which more than offset increased overhead costs.

Previous report

Total deposits increased $113 million during the first nine months of 2025. Aggregate growth in money market deposit accounts totaled $149 million, and interest-bearing checking accounts grew $23.5 million. Noninterest-bearing checking accounts declined $81.7 million; however, excluding the expected withdrawal of funds in early January that had been deposited by a single depositor near the end of 2024, these accounts increased by about $10 million. Securities sold under agreements to repurchase (“sweep accounts”) increased $130 million during the first nine months of 2025, largely reflecting the return of funds that had been withdrawn during the fourth quarter of 2024. Federal Home Loan Bank of Indianapolis (“FHLBI”) advances declined $40.9 million during the first nine months of 2025. Wholesale funds, comprised of out-of-area deposits and FHLBI advances, totaled $525 million, or about 10% of total funds, as of September 30, 2025, compared to $537 million, or about 10% of total funds, as of December 31, 2024.

Previous report

Net interest income increased $3.7 million and $7.3 million during the third quarter and first nine months of 2025, respectively, compared to the same prior-year time periods. Interest income increased $2.2 million and $8.9 million during third quarter and first nine months of 2025, respectively, compared to the same prior-year time periods, while interest expense declined $1.5 million during the third quarter of 2025 compared to the third quarter of 2024 and increased $1.6 million during the first nine months of 2025 compared to the first nine months of 2024. Our net interest margin declined 2 basis points and 13 basis points during the third quarter and first nine months of 2025, respectively, compared to the same prior-year time periods. Our yield on earning assets declined 33 basis points and 30 basis points during the third quarter and first nine months of 2025 during those same respective time periods, while our cost of funds declined 31 basis points and 17 basis points, respectively. The lower yield on earning assets largely reflected the aggregate 100 basis point reduction in the federal funds rate during the last four months of 2024, along with an additional 25 basis point reduction in mid-September of 2025. Despite the reductions in the net interest margin, net interest income increased during the 2025 periods primarily due to solid loan growth between the third quarters of 2024 and 2025. Total loans averaged $4.67 billion and $4.47 billion during the third quarters of 2025 and 2024, respectively, reflecting growth of $201 million, or 4.5%.

Previous report

Noninterest income totaled $10.4 million and $30.6 million during the third quarter and first nine months of 2025, respectively, compared to $9.7 million and $30.2 million during the third quarter and first nine months of 2024, respectively. We recorded increased service charges on accounts, primarily reflecting growth in treasury management activity, credit and debit card fees and payroll services income during both time periods. Mortgage banking income was $0.3 million lower during the third quarter of 2025 compared to the third quarter of 2024, but was $1.0 million higher during the first nine months of 2025 compared to the first nine months of 2024. The level of mortgage banking income is generally reflective of the volume of loans originated with the intent to sell, but quarter-end fair value calculations associated with residential mortgage loan commitments can also play a notable role as it did during the second and third quarters of 2025. Interest rate swap income declined during both time periods in 2025 compared to the respective 2024 time frames, generally reflecting a lower volume of new swap transactions.

Previous report

Noninterest expense totaled $34.8 million and $99.2 million during the third quarter and first nine months of 2025, respectively, compared to $32.3 million and $92.0 million during the third quarter and first nine months of 2024, respectively. The higher level of noninterest expense during both time periods primarily resulted from increased compensation and benefit costs along with higher data processing expenses. Expenses associated with the planned acquisition of Eastern Michigan Financial Corporation totaled $0.6 million during the third quarter and first nine months of 2025.

Previous report

Federal income tax expense totaled $3.7 million and $11.5 million during the third quarter and first nine months of 2025, respectively, compared to $4.9 million and $15.1 million during the third quarter and first nine months of 2024, respectively. The effective tax rate was 13.4% and 14.9% during the third quarter and first nine months of 2025, respectively, compared to 20.1% during both the third quarter and first nine months of 2024. The reduction during the 2025 periods compared to the respective 2024 periods primarily reflects the acquisition of transferable energy tax credits during the second and third quarters of 2025, which provided for a $2.6 million reduction in federal income tax expense.

Previous report

Our total assets increased $256 million during the first nine months of 2025, and totaled $6.31 billion as of September 30, 2025. Loans grew $14.4 million, securities available for sale increased $125 million and interest-earning deposits were up $82.4 million during the first nine months of 2025. Deposits increased $113 million and sweep accounts grew $130 million, while FHLBI advances decreased $40.9 million during the first nine months of 2025.

Previous report

Commercial loans increased $43.0 million during the first nine months of 2025, providing for an annualized growth rate of about 2%. Commercial and industrial loans grew $50.4 million and multi-family and residential rental property loans increased $45.3 million. Non-owner occupied CRE loans declined $37.2 million while owner occupied CRE loans were down $19.4 million; both CRE loan segments were impacted by the payoffs of several larger relationships largely stemming from sales of the underlying properties and refinancings to the secondary market. Land development and construction loans expanded by $3.9 million. As a percent of total commercial loans, commercial and industrial loans and owner occupied CRE loans combined equaled 55.1% as of September 30, 2025, compared to 54.9% as of December 31, 2024. Commercial loans totaled $3.75 billion, or 81.3% of total loans, as of September 30, 2025, compared to $3.71 billion, or 80.6% of total loans, as of December 31, 2024. As anticipated, we did experience several relatively large CRE-related loan payoffs, as well as a reduction in line of credit usage, which negatively impacted commercial loan growth during the third quarter of 2025.

Previous report

Residential mortgage loans totaled $781 million, or 16.9% of total loans, as of September 30, 2025. Residential mortgage loans decreased $46.7 million during the first nine months of 2025, as aggregate payoffs and scheduled monthly payments exceeded new loans added to the portfolio. Residential mortgage loan originations totaled $379 million during the first nine months of 2025, of which about 80% were originated with the intent to sell.

Previous report

Gross loan charge-offs totaled $0.3 million during the first nine months of 2025, while recoveries of prior period loan charge-offs aggregated $1.1 million, providing for a net loan recovery of $0.8 million. We continue our collection efforts on charged-off loans and expect to record recoveries in future periods; however, given the nature of these efforts, it is not practical to forecast the dollar amount and timing of the recoveries. We recorded provision expense of $3.9 million during the first nine months of 2025, primarily reflecting a $4.6 million net increase in specific allocations driven by $5.5 million in total allocations for a commercial construction loan relationship that was placed on nonaccrual during the second quarter of 2025, a $1.9 million reserve increase related to changes to the economic forecast, and a $1.7 million net increase in qualitative factors stemming from changes in the makeup of the loan portfolio.

Previous report

Total deposits increased $113 million during the first nine months of 2025. Aggregate growth in money market deposit accounts totaled $149 million, and interest-bearing checking accounts grew $23.5 million. Noninterest-bearing checking accounts declined $81.7 million; however, these accounts increased about $10 million excluding the expected withdrawal of funds in early January that had been deposited by a single depositor near the end of 2024. Sweep accounts increased $130 million during the first nine months of 2025, largely reflecting the return of funds that had been withdrawn during the fourth quarter of 2024. FHLBI advances declined $40.9 million during the first nine months of 2025. Wholesale funds, comprised of out-of-area deposits and FHLBI advances, totaled $525 million, or about 10% of total funds, as of September 30, 2025, compared to $537 million, or about 10% of total funds, as of December 31, 2024.

Previous report

Interest income during the first nine months of 2025 was $248 million, an increase of $8.9 million, or 3.7%, from the $239 million earned during the first nine months of 2024. The increase resulted from a higher level of average earning assets, which more than offset a lower yield on average earning assets. Average earning assets equaled $5.77 billion during the first nine months of 2025, up $520 million, or 9.9%, from the level of $5.25 billion during the first nine months of 2024; average loans increased $276 million, average securities grew $166 million, and average interest-earning deposits were up $77.7 million. The yield on average earning assets was 5.76% during the first nine months of 2025, a decline from 6.06% during the respective 2024 period. The decreased yield mainly resulted from a lower yield on loans and a change in earning asset mix, which more than offset an improved yield on securities reflecting the reinvestment of relatively low-yielding bonds and portfolio expansion activities. The yield on loans was 6.33% during the first nine months of 2025, down from 6.66% during the first nine months of 2024 largely due to reduced interest rates on variable-rate commercial loans stemming from the aforementioned FOMC interest rate cuts. Higher-yielding loans accounted for a decreased percentage of earning assets and lower-yielding securities and interest-earning deposits represented increased percentages of earning assets in the first nine months of 2025 compared to the first nine months of 2024. A decreased yield on interest-earning deposits, reflecting the lower interest rate environment, also contributed to the reduced yield on average earning assets. The yield on securities equaled 2.97% during the first nine months of 2025, up from 2.31% during the respective 2024 period.

Previous report

Interest expense during the first nine months of 2025 was $97.9 million, an increase of $1.6 million, or 1.7%, from the $96.3 million expensed during the first nine months of 2024. The increased interest expense reflected growth in average interest-bearing liabilities, which more than offset a reduction in the weighted average cost of these funds. Average interest-bearing liabilities totaled $4.25 billion during the first nine months of 2025, compared to $3.77 billion during the respective 2024 period, representing an increase of $483 million, or 12.8%. The average weighted cost of interest-bearing liabilities decreased from 3.40% during the first nine months of 2024 to 3.08% during the first nine months of 2025 mainly due to lower rates paid on money market accounts and time deposits, reflecting the decreased interest rate environment starting in September of 2024 and coinciding with the FOMC’s lowering of the targeted federal funds rate. A change in funding mix, primarily consisting of decreases in average noninterest-bearing checking accounts and lower-cost non-time deposits and increases in average higher-cost money market accounts and time deposits as a percentage of total funding sources, negatively impacted the weighted average cost of interest-bearing liabilities during the first nine months of 2025. The increases in money market accounts and time deposits reflected new deposit relationships, growth in existing deposit relationships, and deposit migration.

Previous report

Net interest income during the first nine months of 2025 was $150 million, an increase of $7.3 million, or 5.1%, from the $143 million earned during the respective 2024 period. The increase reflected earning asset expansion, which more than offset a decreased net interest margin. The net interest margin was 3.49% in the first nine months of 2025, down from 3.62% in the first nine months of 2024 due to a lower yield on earning assets, which outweighed a decreased cost of funds. The reduced yield on average earning assets primarily reflected a decreased yield on commercial loans, in large part stemming from the aforementioned FOMC rate cuts. The cost of funds equaled 2.27% in the first nine months of 2025, down from 2.44% in the respective 2024 period mainly due to lower rates paid on money market accounts and time deposits, in large part reflecting the decreasing interest rate environment during the last four months of 2024.

Previous report

Provisions for credit losses of $0.2 million and $1.1 million were recorded during the third quarters of 2025 and 2024, respectively, and $3.9 million and $5.9 million during the first nine months of 2025 and 2024, respectively. The provision expense recorded during the current-year third quarter mainly reflected a $2.9 million net increase in specific allocations, largely reflecting 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 $2.3 million and $0.9 million reductions in the reserve related to 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, respectively. The provision expense recorded during the first nine months of 2025 primarily reflected a $4.6 million net increase in specific allocations driven by $5.5 million in total allocations for the aforementioned commercial construction loan, a $1.9 million reserve increase related to changes to the economic forecast, and a $1.7 million net increase in qualitative factors stemming from changes in the makeup of the loan portfolio. The impacts of these factors were partially offset by $2.3 million and $1.2 million reductions in the reserve related to faster residential mortgage and consumer loan prepayment speeds and the associated reduced average lives of the portfolios and changes in baseline loss rates, respectively. The provision expense recorded during the third quarter of 2024 mainly reflected an increase in environmental factor allocations and allocations necessitated by net loan growth, which were partially offset by reductions in the calculated allowance due primarily from the payoffs of two larger problem commercial lending relationships previously included in the collective evaluation. The provision expense recorded during the first nine months of 2024 primarily reflected specific allocations for two different nonperforming nonreal-estate-related commercial loan relationships and allocations necessitated by net loan growth, which were partly offset by the previously mentioned decrease in the calculated allowance. The recording of net loan recoveries and sustained strength in loan quality metrics during the 2025 and 2024 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%, from $9.7 million during the respective 2024 period. The increase mainly stemmed from growth in treasury management fees, payroll services fees, and earnings on bank owned life insurance, which more than offset a reduction in mortgage banking income. The increases in treasury management and payroll services fees primarily reflected clients’ expanded use of products and services and new customer acquisition, while the lower level of mortgage banking income mainly 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 included bank owned life insurance death benefit claims totaling $0.3 million.

Previous report

Noninterest income totaled $30.6 million during the first nine months of 2025, compared to $30.2 million during the first nine months of 2024. Bank owned life insurance death benefit claims totaling $0.3 million and $0.7 million were recorded during the first nine months of 2025 and 2024, respectively. Noninterest income during the first nine months of 2024 also included gains on the sales of other real estate owned totaling $0.4 million. Excluding these transactions, noninterest income increased $1.2 million, or 4.0%, in the first nine months of 2025 compared to the respective 2024 period. The growth primarily reflected higher levels of treasury management fees and payroll services fees, largely resulting from customers’ increased use of products and services and successful client acquisition efforts, and mortgage banking income, mainly reflecting increases in the percentage of loans originated with the intent to sell and total loan production, which more than offset decreases in revenue generated from investments in private equity funds and interest rate swap income. The percentage of mortgage loans originated with the intent to sell increased from approximately 77% during the first nine months of 2024 to approximately 80% during the first nine months of 2025, and total mortgage loan originations were up approximately 4% during the respective periods. Interest rate swap income can vary greatly from period to period due to the timing of closing transactions.

Previous report

Noninterest expense totaled $34.8 million during the third quarter of 2025, up from $32.3 million during the prior-year third quarter. Noninterest expense totaled $99.2 million during the first nine months of 2025, compared to $92.0 million during the first nine months of 2024. The increases primarily resulted from higher salary and benefit costs, mainly reflecting annual merit pay increases, market adjustments, and lower residential mortgage loan deferred salary costs; a larger bonus accrual and higher levels of payroll taxes and retirement costs also contributed to the increase in salary and benefit expenses during the first nine months of 2025. Increased data processing costs, primarily reflecting increased software support costs, and allocations to the reserve for unfunded loan commitments, largely stemming from an increase in commercial loan commitments, also contributed to the rises in noninterest expense during the 2025 periods. Lower depreciation expense, mainly reflecting facility expansion and leasehold improvement projects becoming fully depreciated during 2024, positively impacted noninterest expense during both 2025 periods. Contributions to The Mercantile Bank Foundation totaled $0.3 million during the third quarter of 2025 and $0.3 million and $0.7 million during the first nine months of 2025 and 2024, respectively, while acquisition costs related to the planned partnership with Eastern Michigan Financial Corporation totaled $0.6 million during the third quarter and first nine months of 2025.

Previous report

During the third quarter of 2025, we recorded income before federal income tax of $27.5 million and federal income tax expense of $3.7 million. During the third quarter of 2024, we recorded income before federal income tax of $24.5 million and federal income tax expense of $4.9 million. During the first nine months of 2025, we recorded income before federal income tax of $77.4 million and federal income tax expense of $11.5 million. During the first nine months of 2024, we recorded income before federal income tax of $75.1 million and federal income tax expense of $15.1 million. The decreases in federal income tax expense during the 2025 periods primarily reflected the acquisition of transferable energy tax credits during the second and third quarters of 2025, which provided for aggregate tax benefits of $1.0 million and $2.6 million during the current-year third quarter and first nine months of 2025, respectively. Net benefits from investments in tax credit structures provided for aggregate tax benefits of $0.7 million and $1.2 million during the third quarter and first nine months of 2025, respectively. The recording of tax benefits positively impacted our effective tax rate, which equaled 13.4% and 14.9% in the third quarter and first nine months of 2025, respectively, compared to 20.1% in the respective 2024 periods. The previously mentioned bank owned life insurance death benefit claims, substantially all of which were nontaxable, positively impacted the effective tax rates in the third quarter and first nine months of 2025 and first nine months of 2024.

Previous wording

Commercial loans increased $43.0 million during the first nine months of 2025, providing for an annualized growth rate of about 2%. Commercial and industrial loans grew $50.4 million and multi-family and residential rental property loans increased $45.3 million. Non-owner occupied commercial real estate (“CRE”) loans declined $37.2 million while owner occupied CRE loans were down $19.4 million; both CRE loan segments were impacted by the payoffs of several larger relationships largely stemming from sales of the underlying properties and refinancings to the secondary market. Land development and construction loans expanded by $3.9 million. As a percent of total commercial loans, commercial and industrial loans and owner occupied CRE loans combined equaled 55.1% as of September 30, 2025, compared to 54.9% as of December 31, 2024. The commercial loan pipeline remains strong, and as of September 30, 2025, we had $216 million in unfunded loan commitments on commercial construction and development loans that are in the construction phase. As anticipated, we did experience several relatively large CRE-related loan payoffs, as well as a reduction in line of credit usage, both of which negatively impacted commercial loan growth during the third quarter of 2025.

Current wording

Commercial loans increased $16.7 million during the first three months of 2026, providing for an annualized growth rate of about 2%. As had been the case during most of 2025, commercial loan growth during the first quarter of 2026 was negatively impacted by a higher than typical level of payoffs and line of credit paydowns. Commercial loan payoffs, largely reflecting business sales, sales of assets and secondary market refinancings, and line of credit paydowns on larger commercial loan relationships totaled $180 million during the first three months of 2026, after aggregating $363 million, or an average of $91 million per quarter, in 2025. Our typical level of such payoffs and line paydowns average around $50 million per quarter. As a percentage of total commercial loans, commercial and industrial and owner-occupied commercial real estate (“CRE”) loans equaled 56.6% as of March 31, 2026, compared to 55.0% as of December 31, 2025. The commercial loan pipeline remains strong, and as of March 31, 2026, we had $240 million in unfunded loan commitments on commercial construction and development loans that are in the construction phase.

Residential mortgage loans decreased $46.7 million during the first nine months of 2025, as aggregate payoffs and scheduled monthly payments exceeded new loans added to the portfolio. Residential mortgage loan originations totaled $379 million during the first nine months of 2025, of which about 80% were originated with the intent to sell.

Current wording

Residential mortgage loans decreased $22.6 million during the first three months of 2026, as aggregate payoffs and scheduled monthly payments exceeded new loans added to the portfolio during the quarter. Residential mortgage loan originations totaled $128 million during the first quarter of 2026, reflecting an increase of over 27% compared to the first three months of 2025. Approximately 83% of the residential mortgage loans originated during the first quarter of 2026 were with the intent to sell, compared to about 80% during the first three months of 2025. Combined with increased prepayment speeds of our residential mortgage loan portfolio during the past two years, the increased percentage of loans sold has resulted in a declining portfolio balance. The increased volume of residential mortgage loans originated and percentage of loans sold has had a positive impact on mortgage banking income.

Previous wording

The overall quality of our loan portfolio remains strong, with nonperforming loans equaling 0.21% of total loans as of September 30, 2025. Accruing loans past due 30 to 89 days remain very low, and we had no foreclosed properties at quarter end. Gross loan charge-offs totaled $0.3 million during the first nine months of 2025, while recoveries of prior period loan charge-offs aggregated $1.1 million, providing for a net loan recovery of $0.8 million. We recorded provision expense of $3.9 million during the first nine months of 2025, primarily reflecting a $4.6 million net increase in specific allocations driven by $5.5 million in total allocations for a commercial construction loan relationship that was placed on nonaccrual during the second quarter of 2025, a $1.9 million reserve increase related to changes to the economic forecast, and a $1.7 million net increase in qualitative factors stemming from changes in the makeup of the loan portfolio.

Current wording

The overall quality of our loan portfolio remains strong, with nonperforming loans totaling $7.5 million, or 0.16% of total loans, as of March 31, 2026. Accruing loans past due 30 to 89 days remain very low with no foreclosed properties at quarter-end. Gross loan charge-offs were nominal during the first three months of 2026, while recoveries of prior period loan charge-offs aggregated $0.4 million, providing for a net loan recovery of $0.3 million.

Interest-earning deposits, a vast majority of which is comprised of funds on deposit with the Federal Reserve Bank of Chicago, averaged $284 million and $206 million during the first nine months of 2025 and 2024, or almost 5% and 4% of average total assets, respectively. We have generally operated with about 1% to 2% of total assets comprised of interest-earning deposits. The higher average balance of interest-earning deposits primarily reflects our strategy to reduce the loan-to-deposit ratio via local deposit growth exceeding loan and investment growth, as well as our desire to maintain higher levels of on balance sheet liquidity.

Current wording

Interest-earning deposits, a vast majority of which is comprised of funds on deposit with the Federal Reserve Bank of Chicago, averaged $423 million during the first three months of 2026, compared to $267 million during the first three months of 2025.

We had $216 million in unfunded loan commitments on commercial construction and development loans that were in the construction phase as of September 30, 2025, which we expect to be drawn over the next 12 to 18 months. Our current pipeline reports indicate approximately $307 million in new lending opportunities of which we expect a majority to be accepted and funded over the next 12 to 18 months. We remain committed to prudent underwriting standards that provide for an appropriate yield and risk relationship, as well as concentration limits we have established within our commercial loan portfolio. Usage of existing commercial lines of credit averaged about 45% during the first nine months of 2025, compared to approximately 42% during all of 2024.

Current wording

Availability on commercial construction and development loans that are in the construction phase totaled $240 million as of March 31, 2026, with most of the funds expected to be drawn over the next 12 to 18 months. Our current pipeline reports indicate continued strong commercial loan funding opportunities in future periods, including $289 million in committed and accepted new lending commitments, a majority of which we expect to be accepted and funded over the next 12 to 18 months. Our commercial bankers also report additional opportunities they are currently discussing with existing borrowers and potential new customers. We remain committed to prudent underwriting standards that provide for an appropriate yield and risk relationship, as well as concentration limits, we have established within our commercial loan portfolio. Usage of existing commercial lines of credit averaged about 40% during the first three months of 2026, compared to approximately 44% during all of 2025.

Other consumer-related loans, primarily comprised of home equity lines of credit, totaled $83.9 million, or 1.9% of total loans, as of September 30, 2025, compared to $65.9 million, or 1.4% of total loans, as of December 31, 2024. We expect this loan portfolio segment to remain relatively stable in dollar amount but decline as a percentage of total loans in future periods as the commercial loan segment grows.

Current wording

Other consumer-related loans totaled $113 million, or 2.4% of total loans, as of March 31, 2026. Home equity lines of credit comprised approximately 76% of that total balance. We expect this loan portfolio segment to remain relatively stable in dollar amount but decline as a percentage of total loans in future periods as the commercial loan segment grows.

Previous wording

Our credit policies establish guidelines to manage credit risk and asset quality. These guidelines include loan review and early identification of problem loans to provide effective loan portfolio administration. The credit policies and procedures are meant to minimize the risk and uncertainties inherent in lending. In following these policies and procedures, we must rely on estimates, appraisals and evaluations of loans and the possibility that changes in these could occur quickly because of changing economic conditions or other factors. Identified problem loans, which exhibit characteristics (financial or otherwise) that could cause the loans to become nonperforming or require modification in the future, are included on an internal watch list. Senior management and the Board of Directors review this list regularly. Market value estimates of collateral on nonperforming loans, as well as on foreclosed and repossessed assets, are reviewed periodically. We also have a process in place to monitor whether value estimates at each quarter-end are reflective of current market conditions. Our credit policies establish criteria for obtaining appraisals and determining internal value estimates. We may also adjust outside and internal valuations based on identifiable trends within our markets, such as recent sales of similar properties or assets, listing prices and offers received. In addition, we may discount certain appraised and internal value estimates to address distressed market conditions.

Nonperforming loans totaled $9.8 million, or 0.2% of total loans, as of September 30, 2025, compared to $5.7 million, or 0.1% of total loans, as of December 31, 2024. We had no loans past due 90 days or more and accruing interest or foreclosed properties as of September 30, 2025, or December 31, 2024. The volume of nonperforming loans has remained under 0.3% of total loans since year-end 2015. Given the low levels of nonperforming loans and accruing loans delinquent 30 to 89 days, combined with what we believe are strong credit administration practices, we are pleased with the overall quality of the loan portfolio.

Current wording

The overall quality of our loan portfolio remains strong, with nonperforming loans totaling $7.5 million, or 0.2% of total loans, as of March 31, 2026. The volume of nonperforming loans has remained under 0.3% of total loans since year-end 2015 and has averaged 0.1% over the past seven years. Accruing loans past due 30 to 89 days remain very low with no foreclosed properties at quarter end. Given the low levels of nonperforming and delinquent loans, combined with what we believe are strong credit administration practices, we are pleased with the overall quality of the loan portfolio. Gross loan charge-offs were nominal during the first three months of 2026, while recoveries of prior period loan charge-offs aggregated $0.4 million, providing for a net loan recovery of $0.3 million. We continue our collection efforts on charged-off loans and expect to record recoveries in future periods; however, given the nature of these efforts, it is not practical to forecast the dollar amount and timing of the recoveries.

Previous wording

The allowance equaled $59.1 million, or 1.28% of total loans and 601% of nonperforming loans, as of September 30, 2025.

The net unrealized loss equaled $63.1 million as of December 31, 2024. After we considered whether the securities were issued by the federal government or its agencies and whether downgrades by bond rating agencies had occurred, we determined that the unrealized losses were due to changing interest rate environments. We maintain the securities portfolio at levels to provide adequate pledging and secondary liquidity for our daily operations. In addition, the securities portfolio serves a primary interest rate risk management function. We expect any upcoming purchases to generally consist of U.S. Government agency bonds and municipal bonds, with the securities portfolio maintained at about 13% to 16% of total assets.

Sweep accounts increased $130 million during the first nine months of 2025, largely reflecting the return of funds in early 2025 that had been withdrawn during the fourth quarter of 2024. The aggregate balance of sweep accounts is subject to relatively large daily fluctuations given the nature of the customers utilizing this product and the sizable balances that many of the customers maintain.

We recorded net income of $23.8 million, or $1.46 per basic and diluted share, for the third quarter of 2025, compared with net income of $19.6 million, or $1.22 per basic and diluted share, for the third quarter of 2024. We recorded net income of $65.9 million, or $4.06 per basic and diluted share, for the first nine months of 2025, compared with net income of $60.0 million, or $3.72 per basic and diluted share, for the first nine months of 2024. Diluted earnings per share increased $0.24, or 19.7%, during the third quarter of 2025, and $0.34, or 9.1%, during the first nine months of 2025, compared with the respective prior-year periods.

Current wording

We recorded net income of $22.7 million, or $1.32 per basic and diluted share, for the first quarter of 2026, compared with net income of $19.5 million, or $1.21 per basic and diluted share, for the first quarter of 2025. Excluding after-tax one-time costs associated with the year-end 2025 acquisition of Eastern Michigan Financial Corporation and previously announced core and digital banking system conversion (a non-GAAP measurement), net income improved to $25.2 million, or $1.46 per diluted share, for the first quarter of 2026. Diluted earnings per share increased $0.25, or approximately 21%, in the first quarter of 2026 compared to the first quarter of 2025 using this non-GAAP measure. The first quarter of 2026 represented the initial period of financial performance that included Eastern Michigan Bank’s operating results.

Previous wording

The increases in net income during the 2025 periods compared to the respective 2024 periods primarily reflected growth in net interest income and lower levels of federal income tax expense and provisions for credit losses, which more than offset increased noninterest expense. Higher levels of noninterest income, mainly reflecting growth in treasury management fees and payroll services fees during both 2025 periods and an increase in mortgage banking income during the first nine months of 2025, also contributed to the increases in net income. Net interest income increased as earning asset expansion and a decrease in the cost of funds outweighed a lower yield on earning assets and growth in interest-bearing liabilities. The decreases in federal income tax expense primarily resulted from the recognition of tax benefits stemming from the acquisition of transferable energy tax credits during the second quarter and third quarter of 2025; net benefits from investments in tax credit structures also positively impacted federal income tax expense during the current-year third quarter. The provisions for credit losses recorded during the 2025 periods mainly reflected a net increase in specific allocations driven by a commercial construction loan that was placed on nonaccrual during the second quarter and a net increase in qualitative factor allocations reflecting changes in the composition of the loan portfolio. The net impact of changes to the economic forecast also contributed to the provision expense recorded during the first nine months of 2025. Noninterest expense increased during the 2025 periods primarily due to higher levels of salary and benefit and data processing costs and allocations to the reserve for unfunded loan commitments. Acquisition costs related to the previously announced partnership with Eastern Michigan Bank Corporation also contributed to the increases in noninterest expense during the 2025 periods.

Current wording

The increase in net income during the first three months of 2026 compared to the respective prior-year period reflected growth in net interest income and noninterest income and a lower provision for credit losses, which more than offset a higher level of noninterest expense. Net interest income increased as earning asset expansion and a decrease in the cost of funds outweighed a lower yield on earning assets and growth in interest-bearing liabilities. The increase in noninterest income mainly reflected higher levels of treasury management fees, interest rate swap income, and mortgage banking income. The negative provision for credit losses recorded during the first quarter of 2026 primarily reflected improvements to the economic forecast, changes in loan mix, decreases to the residential mortgage loan portfolio, and a decline in specific allocations. Excluding the previously mentioned one-time core and digital banking system conversion and acquisition costs, the increase in noninterest expense during the first three months of 2026 mainly reflected higher levels of salary and benefit and data processing costs and allocations to the reserve for unfunded loan commitments.

Previous wording

Interest income during the third quarter of 2025 was $85.6 million, an increase of $2.2 million, or 2.7%, from the $83.4 million earned during the third quarter of 2024. The increase resulted from growth in average earning assets, which more than offset a lower yield on average earning assets. Average earning assets equaled $5.92 billion during the third quarter of 2025, up $469 million, or 8.6%, from the level of $5.45 billion during the prior-year third quarter; average loans were up $201 million, average securities increased $163 million, and average interest-earning deposits grew $105 million. The yield on average earning assets was 5.75% during the current-year third quarter, a decrease from 6.08% 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% during the third quarter of 2025, down from 6.69% during the third quarter of 2024 primarily due to lower interest rates on variable-rate commercial loans resulting from the 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% 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. A lower yield on interest-earning deposits, reflecting the decreased interest rate environment, also contributed to the reduced yield on average earning assets. The yield on securities equaled 3.04% during the third quarter of 2025, up from 2.43% during the prior-year third quarter.

Current wording

Interest income during the first quarter of 2026 was $85.4 million, an increase of $5.1 million, or 6.3%, from the $80.3 million earned during the first quarter of 2025. The increase resulted from growth in average earning assets, which more than offset a lower yield on average earning assets. Average earning assets equaled $6.42 billion during the first three months of 2026, up $719 million, or 12.6%, from the level of $5.70 billion during the respective 2025 period; average loans were up $199 million, average securities increased $357 million, and average other interest-earning assets grew $163 million. The yield on average earning assets was 5.42% during the first three months of 2026, a decrease from 5.73% during the first three months of 2025. 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, along with the positive impact resulting from the addition of Eastern Michigan Bank’s securities portfolio. The yield on loans was 6.04% during the first quarter of 2026, down from 6.28% during the first quarter of 2025, primarily due to reduced 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 25 basis points in each of September, October, and December of 2025, during which time average variable-rate commercial loans represented approximately 77% of average total commercial loans. Denoting the success of a strategic initiative to lower the loan-to-deposit ratio and increase on-balance sheet liquidity and reflecting the impact of Eastern Michigan Bank’s liquid balance sheet, higher-yielding loans represented a decreased percentage of earning assets and lower-yielding securities accounted for an increased percentage of earning assets in the first quarter of 2026 compared to the first quarter of 2025. The yield on securities equaled 3.27% during the first quarter of 2026, up from 2.73% during the prior-year first quarter. The yield on other interest-earning assets, largely consisting of funds on deposit with the Federal Reserve Bank of Chicago, declined from 4.80% during the first three months of 2025 to 4.00% during the respective 2026 period, reflecting the decreased interest rate environment.

Previous wording

Interest expense during the third quarter of 2025 was $33.6 million, a decrease of $1.5 million, or 4.2%, from the $35.1 million expensed during the third quarter of 2024. The lower level of interest expense resulted from a decrease in the weighted average cost of average interest-bearing liabilities, which more than offset growth in these funds. The average weighted cost of interest-bearing liabilities declined from 3.53% during the third quarter of 2024 to 3.06% during the third quarter of 2025 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. Average interest-bearing liabilities totaled $4.36 billion during the third quarter of 2025, compared to $3.94 billion during the prior-year third quarter, representing an increase of $418 million, or 10.6%.

Current wording

Interest expense during the first quarter of 2026 was $29.5 million, a decrease of $2.3 million, or 7.1%, from the $31.8 million expensed during the first quarter of 2025. The lower level of interest expense resulted from a decrease in the weighted average cost of average interest-bearing liabilities, which more than offset growth in these funds. The average weighted cost of interest-bearing liabilities declined from 3.08% during the first quarter of 2025 to 2.54% during the first quarter of 2026 mainly due to lower rates paid on money market accounts and time deposits, reflecting the decreased interest rate environment. An increase in low-cost deposit products as a percentage of total funding sources, primarily stemming from the onboarding of Eastern Michigan Bank’s deposit base, also contributed to the reduced weighted average cost of average interest-bearing liabilities. During the first three months of 2026, average interest-bearing liabilities totaled $4.71 billion, up $529 million, or 12.6%, from $4.18 billion during the respective 2025 period.

Previous wording

Net interest income during the third quarter of 2025 was $52.0 million, an increase of $3.7 million, or 7.7%, from the $48.3 million earned during the respective 2024 period. The increase reflected growth in earning assets, which more than offset a slightly lower net interest margin. The net interest margin was 3.50% in the current-year third quarter, down from 3.52% in the third quarter of 2024 due to a decreased yield on average earning assets, which more than offset a decline in the cost of funds. The lower yield on average earning assets mainly resulted from a decreased yield on commercial loans, largely reflecting the impact of the previously mentioned FOMC rate cuts. The cost of funds equaled 2.25% in the third quarter of 2025, down from 2.56% in the prior-year third quarter primarily due to lower costs of money market accounts and time deposits, largely reflecting the decreasing interest rate environment over the last four months of 2024.

Current wording

Net interest income during the first quarter of 2026 was $55.9 million, an increase of $7.4 million, or 15.1%, from the $48.5 million earned during the first quarter of 2025. The increase reflected growth in earning assets, along with a higher net interest margin. The net interest margin was 3.55% in the current-year first quarter, up from 3.47% in the first quarter of 2025 due to a decreased cost of funds, which more than offset a lower yield on average earning assets. The cost of funds equaled 1.87% in the first quarter of 2026, down from 2.26% in the prior-year first quarter mainly due to lower costs of money market accounts and time deposits, largely reflecting the decreased interest rate environment, and a higher level of low-cost deposit products primarily stemming from the addition of Eastern Michigan Bank’s deposit base.
