Mercantile Bank ((MBWM)) has held its Q4 earnings call. Read on for the main highlights of the call.

Mercantile Bank Balances Growth Ambitions With Margin Resilience in Latest Earnings Call

Mercantile Bank’s latest earnings call conveyed a broadly constructive tone, underscored by strong earnings growth, solid credit performance, and improved balance-sheet strength. Management highlighted stable net interest margins despite lower short-term rates, robust deposit expansion, and healthy capital levels, while also acknowledging headwinds from loan yield compression, elevated loan payoffs, and rising noninterest expenses tied to growth and integration initiatives. Overall, the message was one of disciplined growth and cautious optimism, with management intent on using its fortified position to invest in future expansion.

Eastern Michigan Bank Acquisition Bolsters Liquidity and Margin Outlook

The completion of the Eastern Michigan Bank acquisition on December 31, 2025, was a central theme of the call, framed as both a strategic and financial win. Management emphasized successful execution around systems integration and the acquisition’s role in enhancing liquidity, supporting loan growth, and stabilizing margins. The Eastern franchise is expected to improve the deposit mix and funding profile, helping to offset margin pressure from falling benchmark rates. Executives also underscored that the deal adds scale in key markets and positions the bank to capture more business in Michigan while laying the groundwork for stronger long-term earnings power.

Earnings Momentum: Double-Digit EPS Growth

Mercantile delivered another year of solid profitability, with Q4 2025 net income rising to $22.8 million, or $1.40 per diluted share, up from $19.6 million, or $1.22, a year earlier. For full-year 2025, net income reached $88.8 million, translating to $5.47 per share compared with $79.6 million, or $4.93, in 2024—an 11% increase in EPS. Management highlighted this performance as evidence that the bank is generating profitable growth despite a more challenging rate environment and higher operating costs. The results reflect a combination of net interest income gains, fee-income growth, and disciplined credit management, all achieved while absorbing integration and investment-related expenses.

Net Interest Income Growth and Margin Stability in a Falling-Rate Environment

A key focus for investors—net interest income (NII) and margin—showed resilience. NII increased by $2.7 million in Q4 and $10.0 million for full-year 2025 versus the prior year, even as the 90-day average SOFR rate dropped by 68 basis points. The net interest margin edged up 2 basis points to 3.43% in Q4 on a five-quarter trend basis and has averaged roughly 3.46% in recent quarters. Management stressed that maintaining, and modestly expanding, margin in a declining rate environment reflects proactive balance-sheet management, improved funding mix, and contribution from the Eastern Michigan Bank acquisition.

Deposit and Loan Growth Track Record Remains Strong

Mercantile underscored its long-term growth profile, citing a five-year compounded annual growth rate of 9.2% for deposits and 8.6% for loans. Average deposits climbed to $4.83 billion in 2025, up $302 million from 2024, reflecting success in winning and retaining customers in its markets. While loan growth has been pressured more recently by elevated payoffs, the broader track record points to sustained franchise expansion. Management portrayed this growth as organic and relationship-driven, supporting recurring revenue and reinforcing the bank’s competitive positioning.

Improved Liquidity and a Healthier Loan-to-Deposit Ratio

Balance-sheet strength featured prominently, with the bank highlighting a notable improvement in liquidity metrics. The loan-to-deposit ratio improved to 91% at year-end 2025, down from 98% a year earlier and 110% at the end of 2023, signaling reduced reliance on wholesale funding and greater balance-sheet flexibility. The deposit mix has also become more favorable, with 25% of deposits noninterest-bearing and 24% categorized as lower-cost deposits, up from 20% in the prior quarter. Management described these trends as key to sustaining margin and supporting future loan growth without sacrificing credit discipline.

Fee Income and Mortgage Banking Provide Diversified Revenue

Noninterest income was another bright spot, particularly from treasury, deposit, and mortgage activities. Service charges on accounts increased 19% in 2025, and payroll services revenue grew 14%, demonstrating healthy uptake of fee-based products. Mortgage banking income rose 6% year over year, supported by rising mortgage market share and stronger saleable loan production. Executives framed this diversified fee-income momentum as a valuable offset to rate-driven NII pressures and a sign of deeper client engagement across business lines.

Capital Strength Underpins Strategic Flexibility

Mercantile emphasized its robust capital profile as a competitive advantage. The total risk-based capital ratio for the bank stood at 13.8% at year-end 2025, roughly $213 million above the well-capitalized minimum, while the acquired Eastern franchise reported a 15.3% ratio, about $520 million above its threshold. Tangible book value per share increased by $3.64, or roughly 11%, over the year, reflecting retained earnings and balance-sheet stability. Management highlighted that this capital strength provides ample capacity to support loan growth, absorb integration and technology investments, and potentially pursue future capital management actions.

High Levels of Loan Commitments Point to Future Growth

The call highlighted a robust pipeline of future lending activity. As of December 31, 2025, loan commitments totaled $297 million, including $271 million directed toward commercial and residential construction projects—a historically high level for the bank. Management framed this as an encouraging indicator of future loan fundings, especially as construction projects progress. While timing of draws remains uncertain, these commitments suggest underlying demand remains healthy in core markets, giving the bank confidence in its forward loan growth outlook.

Asset Quality Remains Strong With Solid Credit Coverage

Credit metrics remained a clear strength. Days past due were just 11 basis points of total loans, and the six-year average for nonperforming loans stands at a low 12 basis points. The allowance for credit losses was 1.21% of total loans at year-end 2025, up slightly from 1.18% the prior year, underscoring continued conservative reserving. Management stressed that overall asset quality remains very strong despite isolated credit issues and that underwriting standards have not been relaxed in pursuit of growth, an important reassurance for investors focused on late-cycle credit risk.

Loan Yield Compression Weighs on Interest Income

Despite overall margin stability, loan yields came under pressure in 2025. The yield on loans declined 26 basis points versus 2024, driven by a roughly 75-basis-point decline in the federal funds rate later in the year. Interest income on loans fell both in Q4 and for the full year and was not fully offset by volume growth. Management acknowledged that rate cuts have a lagging effect on commercial loan repricing, and that yields will likely remain under pressure near term, even as the bank works to mitigate this through improved funding mix and selective loan pricing.

Elevated Loan Payoffs Temper Near-Term Loan Growth

Loan growth has also been constrained by higher-than-normal payoffs. Management noted a particularly elevated level of loan payoffs in recent quarters, which dampened loan growth in Q4 and is expected to weigh on early 2026 growth as well. These payoffs, often related to borrowers refinancing or selling assets, reduce outstanding balances even as new originations remain solid. While not indicative of deteriorating credit, the dynamic creates a headwind for reported loan growth figures and adds another variable to the bank’s near-term growth outlook.

Noninterest Expenses Rise With Growth and Integration Investments

Operating costs moved higher in 2025 as the bank invested in people, technology, and integration. Noninterest expenses rose $2.9 million in Q4 and $10.2 million for the full year versus 2024. The increase was driven by higher salaries and benefits, data processing and transaction volume costs, support for new products, and acquisition-related expenses of $1.2 million in Q4 and $1.8 million for the year. Management framed these cost increases as largely strategic, tied to growth initiatives and infrastructure buildout, though they acknowledged that near-term expense pressure is a reality investors should factor into expectations.

Provision and Reserve Volatility Driven by Specific Credit

Provision expense was somewhat volatile but remained manageable. In Q4, the bank recorded a negative provision of $0.7 million, reflecting favorable credit trends and reserve adjustments. For full-year 2025, however, provision expense totaled $3.2 million, down from $7.4 million in 2024. The year included a $5.5 million allocation tied to a specific commercial construction relationship that was placed on nonaccrual status, emphasizing the impact of isolated larger credits in an otherwise clean portfolio. Net loan charge-offs were modest at $1.9 million for the year, consistent with the bank’s overall strong asset quality narrative.

Interest Expense Dynamics Reflect Growth in Deposits

The bank’s funding costs presented a mixed picture. While the average cost of deposits declined by roughly 32 basis points in 2025 compared with 2024, reflecting some benefit from the rate environment and mix improvements, absolute interest expense on deposits increased over the year. This was driven by a $483 million increase in average deposits, which raised total interest paid despite the lower rate. Management underscored that the shift toward more low-cost and noninterest-bearing deposits is key to controlling funding costs and preserving margin as the balance sheet continues to grow.

Strategic Investments and Transition Costs Pressure Near-Term Earnings

Management was candid about the near-term cost impact of strategic investments. Planned personnel additions—particularly for expansion in Southeast Michigan—and a major core and digital provider conversion slated for early 2027 will push noninterest expenses higher before full cost savings are realized. Additionally, core deposit intangible amortization of about $900,000 per quarter will be an ongoing headwind in the expense line. While investors are likely to feel the impact of these costs in 2026, management framed them as necessary to support growth, improve efficiency, and strengthen the customer experience in the years ahead.

Limited Share Repurchases as Capital Is Deployed Elsewhere

Mercantile’s capital return strategy remains conservative in the near term. The company did not repurchase any shares in 2025 and has $6.8 million remaining under its existing repurchase authorization. Management signaled a growing appetite for buybacks but suggested that immediate activity will remain limited as capital is prioritized for organic growth, integration of Eastern Michigan Bank, and technology investments. For shareholders, this indicates that near-term returns will rely more on earnings growth and potential dividend actions than on aggressive repurchase activity.

Forward-Looking Guidance: Steady Rates, Modest Margin Expansion, and Investment-Driven Costs

Looking ahead to 2026, management’s guidance is built on the assumption that year-end interest rates, including the December rate cut, remain unchanged. Under that scenario, the bank is targeting annualized loan growth of 5%–7%, with commercial loans expected to grow around 6%–7% and residential portfolios remaining stable. The loan-to-deposit ratio, currently 91%, is projected to drift higher as loan fundings outpace deposit growth. Net interest margin is expected to edge up from the recent average near 3.46%, with management projecting roughly 3.55%–3.65% in the first quarter and then modest increases of about 5 basis points per quarter as lower-yielding loans and securities roll off and higher-yielding time deposits are added. Guidance also assumes a federal tax rate of about 17% and ongoing quarterly core deposit intangible amortization of roughly $900,000. Management cautioned, however, that this outlook is sensitive to rate movements, loan growth realization, and tax-related assumptions, and they reiterated that near-term noninterest expense will remain elevated due to integration and expansion efforts, with more tangible cost savings not expected until 2027.

In closing, Mercantile Bank’s earnings call painted a picture of a franchise that is growing prudently, investing for the future, and managing risks carefully in a changing rate environment. Strong capital, solid asset quality, and expanding fee income provide a sturdy foundation, while the Eastern Michigan Bank acquisition and robust loan commitments offer a clear runway for future growth. At the same time, investors will need to weigh near-term pressures from loan yield compression, elevated payoffs, and higher operating costs against the bank’s potential to convert today’s investments into stronger earnings and efficiency over the next several years.
