Mercantile Bank Corporation (MBWM) - Canvas Business Model: Key Partnerships

You're looking at the critical relationships that underpin Mercantile Bank Corporation's growth and operational stability as of late 2025. These aren't just vendor agreements; they are strategic alignments that directly impact balance sheet strength and future technology capabilities.

Strategic partnership with Eastern Michigan Financial Corporation

The definitive merger agreement with Eastern Michigan Financial Corporation (EFIN), announced on July 22, 2025, is the most significant partnership move, set to close in the fourth quarter of 2025. This combination is designed to solidify Mercantile Bank Corporation's standing as the largest bank founded, headquartered, and operated in Michigan by total assets. Eastern Michigan Bank will operate alongside Mercantile Bank until the first quarter of 2027, when consolidation onto Mercantile Bank's systems is planned.

Here are the key financial metrics associated with the EFIN combination, based on data as of June 30, 2025:

The deal is projected to be approximately 11% accretive to Mercantile Bank Corporation's dilutive earnings per share once all cost savings are phased in.

Technology vendors for digital banking and core processing

A key element of the EFIN partnership is the planned full core banking system transformation for Mercantile Bank Corporation, which will be executed in partnership with a major vendor.

• Technology Partner: Jack Henry, an industry leading financial technology provider, is central to the core banking system transformation.
• Operational Advantage: Eastern Michigan Bank brings over 40 years of operational experience on the Jack Henry platform, which will support a smoother transition for Mercantile Bank.
• Noninterest Expense Impact: Higher data processing costs were noted in Q3 2025, reflecting increased transaction volumes and software support costs, which is expected to stabilize post-migration.

Correspondent banking relationships for wholesale funding and services

While Mercantile Bank Corporation emphasizes local deposit generation, wholesale funding remains a component of its overall funding mix, which the EFIN acquisition is intended to strengthen through added liquidity.

• Wholesale Funds Level: Wholesale funds stood at $555 million, representing approximately 10% of total funds, as of June 30, 2025.
• Deposit Mix (Q3 2025): Noninterest-bearing deposits represented approximately 25% of total deposits, with lower-cost deposits at 20% of total deposits as of September 30, 2025.
• Loan-to-Deposit Ratio Improvement: The ratio stood at 96% as of September 30, 2025, down from 100% at June 30, 2025, reflecting a strategic goal to lower this metric through deposit growth.

Tax credit syndication partners for federal income tax reduction

Mercantile Bank Corporation utilizes its wholly owned subsidiary, Mercantile Community Partners (MCP), to engage in tax credit investments, which directly reduces its federal income tax expense.

• Subsidiary Focus: MCP acts as a "one-stop-shop" for lending and tax credit investment, focusing on Low-Income Housing Tax Credits (LIHTCs) and Historic Tax Credits (HTCs).
• Total Equity Investments (MCP): MCP has made total equity investments of $48,900,000 in community development projects.
• Tax Rate Impact (Q2 2025): The recognition of tax credit syndication fees and the acquisition of transferable energy tax credits resulted in an effective tax rate of 12.9% in Q2 2025, significantly down from 20.1% in Q2 2024.
• Federal Income Tax Expense Reduction (9M 2025): Federal income tax expense was reduced by $3.6 million for the first nine months of 2025 compared to the prior-year period.
• Near-Term Tax Benefit: Mercantile Bank Corporation was scheduled to close on another transferable energy tax credit by the end of October 2025, expected to reduce federal income tax expense by about $950,000.

Mercantile Bank Corporation (MBWM) - Canvas Business Model: Key Activities

You're looking at the core engine of Mercantile Bank Corporation, the day-to-day work that drives their financial results as of late 2025. Honestly, for a community-focused bank, it all boils down to managing credit risk while aggressively gathering low-cost funding.

Commercial loan origination and portfolio management

This activity centers on originating and managing the commercial loan book, which is the bank's primary asset class. The focus remains on relationship banking, though the pace of origination can fluctuate with the economic environment. For instance, during the first quarter of 2025, the commercial loan portfolio grew at an annualized rate of 4.8%, even with about $55 million in full payoffs and partial paydowns during that period. Commercial loans represent a significant 81% of the total loan portfolio as of the first quarter of 2025. You should note that asset quality remains exceptionally strong; nonperforming assets were less than 0.1% of total assets as of March 31, 2025. The overall loan-to-deposit ratio, a key measure of funding reliance, was brought down to 96% as of September 30, 2025, down from 98% at year-end 2024, showing a strategic shift toward deposit funding.

Generating local deposit growth and client acquisition

This is a critical, stated strategic goal for Mercantile Bank Corporation: growing the local deposit base to lower reliance on wholesale funding and reduce the loan-to-deposit ratio. The success here is clear in the numbers. For the third quarter of 2025, the annualized deposit growth rate was 9%. Over the last six year-end periods, total deposits show a compounded annual growth rate of 11.8%, outpacing the total loans CAGR of 10% over the same timeframe. Average deposits for the third quarter of 2025 totaled $4.83 billion, an increase of $489 million, or over 11%, compared to the third quarter of 2024. This strong local deposit generation helped push the loan-to-deposit ratio down to 96% by September 30, 2025. The bank is definitely prioritizing this over raw loan growth, as loans contracted an annualized 7% in Q3 2025.

• Net growth in local deposit relationships offset seasonal withdrawals.
• The planned acquisition of Eastern Michigan Financial Corporation is expected to further enhance liquidity.
• Noninterest-bearing deposits represented 25% of the total deposit mix as of Q3 2025.

Providing treasury management and payroll services

Fee income from services like treasury management and payroll is a key noninterest income driver. This area showed noteworthy expansion in the third quarter of 2025 compared to the prior year. Specifically, treasury management fees saw an approximate increase of 11%, and payroll services fees jumped by approximately 16%. Noninterest income for the third quarter of 2025 totaled $10.4 million, up from $9.7 million in the third quarter of 2024. This growth in service fees helped offset a reduction in mortgage banking income for the quarter.

Managing the investment securities portfolio

As the bank successfully grows deposits faster than loans, the excess liquidity is deployed into the investment securities portfolio. This activity is essential for maintaining the strategic goal of lowering the loan-to-deposit ratio and managing overall balance sheet structure. The yield on average earning assets was 5.75% during the third quarter of 2025, while the net interest margin stood at 3.50%. The lower yield on securities, compared to loans, is a direct trade-off for the improved funding profile. The loan-to-deposit ratio decline to 96% as of September 30, 2025, was partly attributed to the expansion of the securities portfolio using new deposit monies.

Here's a quick look at how the Q3 2025 results tie into these core activities:

The tangible book value per common share reached $37.41 as of September 30, 2025, showing shareholder value creation from these combined activities.

Mercantile Bank Corporation (MBWM) - Canvas Business Model: Key Resources

You're looking at the core assets that keep Mercantile Bank Corporation running strong as of late 2025. Honestly, the bank's financial foundation is built on capital strength and a loyal funding base. This isn't just talk; the numbers back it up.

Mercantile Bank Corporation maintains a well-capitalized regulatory status, which is a huge resource in this environment. As of September 30, 2025, the bank's total risk-based capital ratio stood at a solid 14.3%. That ratio puts them significantly above the minimum requirement. To be precise, as of that date, Mercantile Bank had approximately $236 million in capital exceeding the 10 percent minimum threshold needed to be classified as well-capitalized.

The funding side of the equation is anchored by local relationships. The local deposit base is a key resource, and as requested, we see figures pointing to a total deposit base of $4.81 billion as of September 30, 2025. This base is sticky, too. The mix shows that noninterest-bearing deposits made up approximately 25 percent of total deposits, and another 20 percent came from lower cost deposits as of that same date. This deposit structure helps keep the net interest margin stable, which is definitely a resource in itself.

Here's a quick look at some of the key financial resources supporting the business model:

Beyond the balance sheet figures, the human capital-the experienced commercial lending teams and relationship managers-is critical for deploying that capital effectively. These teams focus on relationship-based lending, which feeds back into the strong local deposit base. The loan portfolio composition reflects this focus on core commercial relationships.

The expertise of the lending staff is evident in the loan mix:

• Commercial and industrial loans represented a significant portion of the portfolio.
• Owner-occupied commercial real estate loans are also a core focus area.
• These two categories combined made up approximately 55 percent of total commercial loans as of September 30, 2025.
• The bank is actively managing its loan-to-deposit ratio, which stood at 96% as of September 30, 2025, down from 102% a year prior.

Mercantile Bank Corporation (MBWM) - Canvas Business Model: Value Propositions

You're looking at what Mercantile Bank Corporation actually delivers to its clients-the core reasons they choose them over the competition in the Michigan market. It's not just about deposits and loans; it's about specialized service and rock-solid stability.

The high-service model is a clear differentiator, especially for commercial clients who need more than just a standard transaction account. This is where specialized services shine. For instance, the success of their high-service approach is reflected in the fee income growth. Payroll service fees expanded by 15.2% in the first six months of 2025 year-over-year. Furthermore, in the third quarter of 2025, treasury management and payroll services fees saw noteworthy increases of approximately 16% compared to the prior year. This focus on integrated services supports business operations directly.

Their commercial lending remains a key value driver, showing discipline with a 55-45 split between Commercial and Industrial (C&I) loans and owner-occupied Commercial Real Estate (CRE) loans across their commercial segments as of Q3 2025. This disciplined growth is supported by a healthy expansion, with core commercial loans increasing by 7% over the year leading up to Q2 2025.

For you, the investor or partner, the bank's financial health is a core value proposition in itself. Asset quality remains exceptionally strong, which translates directly into lower risk for your relationship. Nonperforming assets totaled only $9.7 million as of June 30, 2025. That figure represents just 0.16% of total assets at that time. To put a finer point on credit management, the bank reported net loan charge-offs to average loans of -0.01% (annualized) for Q2 2025, meaning they actually saw net recoveries for that period. Their capital position backs this up, with a total risk-based capital ratio of 14.4% at the end of Q2 2025.

Mercantile Bank Corporation is positioning itself as the financial partner of choice specifically within the West and Mid-Michigan markets. While headquartered in Grand Rapids, their operations are centered there and in Central Michigan, with offices also in the Detroit metropolitan area, Traverse City, Saginaw, and Midland. The strategic move to acquire Eastern Michigan Financial Corporation is designed to solidify this regional dominance, projecting the combined entity to reach approximately $6.7 billion in assets. This local focus, backed by total assets of $6.18 billion as of Q2 2025, provides the scale necessary to deliver sophisticated solutions while maintaining that community-focused service level.

Here is a quick look at the metrics supporting these value claims as of mid-to-late 2025:

Mercantile Bank Corporation (MBWM) - Canvas Business Model: Channels

You're looking at how Mercantile Bank Corporation (MBWM) gets its value proposition to its customers right now, late 2025. It's a mix of old-school presence and digital push, which is typical for a regional bank focused on Michigan.

Network of physical bank branches across West and Mid-Michigan

Mercantile Bank Corporation maintains a physical footprint across Michigan to serve its community base. As of late 2025, the bank operates a network that includes physical locations supporting in-person transactions and relationship building.

• Total physical offices reported as 40 offices plus three loan production offices (LPOs) in Michigan.
• The total number of locations is cited as 41.
• Of the 40 offices, 27 now contain virtual banking machines (VBMs).
• Mercantile Bank Corporation is the largest bank headquartered in Michigan, with over 40 locations across the state.

Commercial lending officers and business development teams

The success in commercial lending is a direct result of the efforts of these teams, which drive loan origination and client acquisition. Their performance is reflected in the growth figures reported through the first nine months of 2025.

The commercial loan portfolio growth shows the channel is working effectively. For the first six months of 2025, commercial loan growth was $114 million, representing an annualized rate of 6.2%. Furthermore, the commercial loan portfolio maintained a stable mix, holding a 55-45 split between C&I (Commercial & Industrial) and owner-occupied CRE (Commercial Real Estate) loans.

Digital banking platforms (online and mobile) for retail and business

Digital channels are clearly a focus, with a dedicated Senior Vice President and Chief Digital Banking Officer spearheading transformation efforts for online and mobile banking platforms. The increased transaction volumes and new product introductions are driving fee income through these digital touchpoints.

Here's a quick look at how fee-based services, often tied to digital usage and treasury management, performed in the first nine months of 2025 compared to the prior year:

The bank also saw a 20% increase in Service Charges on Accounts in Q1 2025 due to higher activity.

ATM network access for customer convenience

Customer convenience extends beyond the physical branches through strategic ATM partnerships. This provides broad, low-cost access to cash for customers.

• Mercantile Bank partners with MoneyPass® to offer no ATM fees or surcharge fees at over 34,000 MoneyPass® Network ATMs.
• The bank's total assets were $6.18 billion as of Q2 2025, and $6.1 billion as of Q3 2025.

The loan-to-deposit ratio improved, moving from 107% at June 30, 2024, to just under 100% at June 30, 2025, indicating a healthier balance sheet supported by deposit channels.

Mercantile Bank Corporation (MBWM) - Canvas Business Model: Customer Segments

You're looking at the core groups Mercantile Bank Corporation (MBWM) serves, which are heavily weighted toward the business community in Michigan. Honestly, the numbers show a clear focus on commercial relationships over pure retail banking.

Commercial and Industrial (C&I) businesses

This segment forms the backbone of Mercantile Bank Corporation's lending activity. The bank's strategy heavily favors commercial clients, which is evident in the loan portfolio composition as of late 2025. Commercial loans represent the vast majority of their assets.

Owner-Occupied Commercial Real Estate (CRE) borrowers

This group, along with C&I, forms a key lending concentration. The bank views potential CRE headwinds as mitigated by a moderate investor CRE concentration, which stood at approximately 222% of risk-based capital as of the third quarter (3Q25).

Local small to mid-sized businesses needing treasury and payroll services

Beyond lending, Mercantile Bank Corporation actively serves these businesses through fee-based services. The growth in these services is a key indicator of the depth of these customer relationships. For example, payroll services fees saw a significant increase.

• Treasury management fees increased approximately 11% in Q3 2025 over Q3 2024.
• Payroll services fees increased approximately 16% in Q3 2025 over Q3 2024.
• Noninterest-bearing checking accounts, a key indicator of operating deposit relationships, represented about 25% of total deposits as of March 31, 2025.

The bank's focus on local deposit generation is directly tied to servicing these business clients.

Local retail consumers and individual deposit holders

While the primary focus is commercial, retail consumers provide a critical, stable funding base through deposits. As of the second quarter (Q2 2025), personal deposits made up 34% of the total deposit base, compared to 66% from business deposits. The bank has been successful in growing this base locally.

Here's a quick look at the overall loan and deposit structure as of the third quarter of 2025 (9M25 data) to show how these segments translate into the balance sheet:

The total loan portfolio was approximately $4.6 billion on average during Q3 2025. The bank's emphasis on commercial lending means that the C&I and CRE segments are the primary drivers of their asset side, while local retail and business deposits fund that activity.

Mercantile Bank Corporation (MBWM) - Canvas Business Model: Cost Structure

You're looking at the core expenses that drive Mercantile Bank Corporation's operations as of late 2025. For a bank, the cost structure is heavily weighted toward the cost of funding its assets-that is, what it pays for deposits-and the necessary overhead to run the business and manage risk.

Interest Expense on Deposits, Particularly Money Market and Time Deposits

The cost of funds has been a dynamic area, reflecting the interest rate environment. For the second quarter ending in June 2025, the Interest Expense on Deposits was reported at $25.7 million for that quarter alone. To give you a sense of the mix shift, as of Q2 2025, higher-cost deposits increased by three percentage points compared to the prior year, while lower-cost deposits and non-interest-bearing deposits each lost 1 and 2 percentage points of total deposits, respectively. This migration toward higher-cost funding puts pressure on the net interest margin, though management has been working to offset this. For the third quarter of 2025, the cost of funds settled at 2.25 percent, an improvement from 2.56 percent in the third quarter of 2024, largely due to lower rates paid on money market accounts and time deposits following the September 2024 rate decreases.

Here's a look at some related expense and income figures from the first half of 2025:

Non-Interest Costs, Including Overhead and Personnel Expenses

Non-interest expense captures the day-to-day running costs, excluding the interest paid to depositors. For the first quarter of 2025, Mercantile Bank Corporation's Noninterest expense was $31.1 million, up from $29.9 million in the first quarter of 2024. Looking ahead, management projected overhead costs for the remaining quarters of 2025 to fall between $32.5 million and $34.0 million per quarter. Personnel costs are a significant component of this overhead. The bank also saw growth in noninterest income from services, which helps offset these operating costs; for instance, treasury management and payroll services fees increased by approximately 11 percent and 16 percent, respectively, in Q3 2025.

Provision for Credit Losses

Managing potential loan losses is a critical, though often lumpy, cost. As you specified, the Provision for Credit Losses recorded by Mercantile Bank Corporation for the first nine months of 2025 was $3.9 million. [cite: ] To put that in context with recent quarterly data, the provision was $2.1 million in Q1 2025 and only $0.2 million in Q3 2025. The bank has maintained strong asset quality, with nonperforming assets at less than 0.1 percent of total assets as of September 30, 2025.

Regulatory Compliance and Technology Infrastructure Costs

These costs are embedded within the overall non-interest expense structure. You can expect significant spending here to meet evolving regulatory requirements for a bank of this size and to maintain the necessary technology infrastructure for digital banking services and security. While specific line items for regulatory compliance and technology infrastructure are not explicitly detailed with standalone dollar amounts in the latest reports, they are a material driver of the reported quarterly overhead expense figures, such as the $31.1 million in Noninterest expense reported for Q1 2025.

• Regulatory compliance costs are necessary for maintaining a 'well-capitalized' status.
• Technology infrastructure supports treasury management and digital platforms.
• These expenses are managed as part of the overall overhead budget.

Mercantile Bank Corporation (MBWM) - Canvas Business Model: Revenue Streams

The core revenue engine for Mercantile Bank Corporation is its Net Interest Income (NII), which reflects the spread between what the bank earns on its assets, like loans and securities, and what it pays on its liabilities, like deposits. For the third quarter of 2025, NII reached $52.0 million, marking a nearly 8% expansion, or an increase of $3.7 million, compared to the $48.3 million earned in the third quarter of 2024. This growth was driven by an increase in earning assets, which successfully offset a slightly lower net interest margin of 3.50% in Q3 2025, down from 3.52% in Q3 2024.

Total revenue, which combines NII and noninterest income, was $62.4 million for the third quarter of 2025, representing a 7.6% increase from the $58.0 million reported in the prior-year third quarter. You can see the breakdown of the primary revenue drivers here:

Noninterest income, which is fee-based revenue, totaled $10.4 million in the third quarter of 2025, up 7.5% from $9.7 million in the third quarter of 2024. This segment saw strong performance from several service-related offerings, though it was partially offset by fluctuations in mortgage banking income related to fair value adjustments on commitments.

The growth in fee income is concentrated in specific service areas, showing the success of Mercantile Bank Corporation's commercial and business service offerings. Here are the reported growth figures for key fee categories:

• Treasury management fees saw noteworthy increases of approximately 11% in the third quarter of 2025.
• Payroll services fees grew by approximately 16% in the third quarter of 2025.
• Growth in service charges on accounts was strong, increasing by 18.1% for the first nine months of 2025 year-over-year.
• Payroll services for the first nine months of 2025 showed a consistent growth rate of 15%.
• Mortgage banking income contributed positively, growing by 12% for the first nine months of 2025 compared to the prior-year period.

The bank's strategy to grow commercial deposit relationships is directly feeding the treasury management services revenue stream. Still, you should note that the reported Q3 2025 growth for mortgage banking income was tempered by changes in the quarter-end fair value of commitments to originate salable residential mortgage loans.
