• Cash Dividends: 6.0% CAGR
• Tangible Book Value per Share: 8.4% CAGR

Mercantile Bank’s strong performance continues 
to support a well-capitalized regulatory position, 
with a total risk-based capital ratio of 13.9% and 
approximately $214 million more than the 10% 
minimum threshold required to be categorized as 
a “well-capitalized” institution at year-end 2024.

The success of Mercantile is attributed to the 
dedicated efforts of our employees and the 
support of our incredible customer base. We are 
deeply grateful for both groups. Our customers 
are the reason for our existence, and we strive to 
provide them with the best possible experience 
as they work with us to achieve their dreams and 
aspirations. Our committed colleagues make these 
experiences possible, distinguishing Mercantile 
from our competitors. While buildings and products 
may be similar, it is our people who create the 
unique culture of our Bank. This culture drives our 
approach, philosophy, and processes, resulting in 
positive customer experiences daily. 

Community is a core element of our culture, and in 
2024, we strengthened the communities we serve 
through the following tangible actions: 

• Our giving program awarded over $1 million
to organizations who provide support to our
communities.

• Our volunteer program saw 574 Mercantile
employees contributing over 27,500 hours
of community service with nearly 1,000
organizations.

• Mercantile employees served as directors on

more than 300 boards.

• We conducted over 400 financial education

classes, reaching more than 4,300 adults and
children.

• We administered four Federal Home Loan
Bank of Indianapolis Affordable Housing
Grants totaling more than $3.5 million, which
supported the development of 91 housing
units for individuals at or below 80% of area
median income.

• We made 116 community development loans

totaling more than $480 million.

As we conclude 2024, we express our gratitude 
to our shareholders, customers, and employees 
for their support throughout the year. As we enter 
2025, we pledge to continue adhering to the 
principles of excellence that have characterized
our history.

Ray Reitsma
President and CEO
Mercantile Bank Corporation

A letter to our Shareholders.

Since opening our doors in 1997, Mercantile 
Bank has consistently demonstrated unwavering 
commitment to excellence, which has driven our 
strong financial performance. This commitment, 
shared by our entire team, has resulted in solid 
financial results for our shareholders, continued 
investment in our communities, and a strong culture 
for our employees.

In 2024, Mercantile delivered net income of $79.6 
million for our shareholders, driven by outstanding 
performance in the following areas:

• Significant local deposit growth of more than
20%, enabling customers to build resources
for their goals and dreams.

• Nearly 9% growth in commercial loans,

supporting our existing customers’ expansion
and attracting new customers to Mercantile’s
value proposition.

• A 62% increase in mortgage banking

income despite relatively high interest
rates, supporting the American Dream of
homeownership.

• A 38% increase in treasury management
income, ensuring security and safety for
our customers’ ongoing cash management
needs.

• Low levels of nonperforming assets

representing only nine basis points of total
assets at year-end.

• Well controlled overhead costs representing
slightly more than 2% of total assets and
resulting in an efficiency ratio of 54% as
we practiced stewardship over entrusted
resources.

Twenty twenty-four marked another successful 
year in our long history of building value for our 
shareholders. Over the last five years, Mercantile 
has posted strong compounded annual growth 
rates (CAGR) in key categories including:

• Total Loans: 10.0% CAGR
• Total Deposits: 11.8% CAGR
• Earnings per Share: 10.4% CAGR

Item 1.

Business.

The Company

PART I

Mercantile Bank Corporation is a registered bank holding company under the Bank Holding Company Act of 1956, as amended (the 

“Bank Holding Company Act”). Unless the text clearly suggests otherwise, references to “us,” “we,” “our,” or “the company” include 
Mercantile Bank Corporation and its wholly-owned subsidiaries. As a bank holding company, we are subject to regulation by the Board of 
Governors of the Federal Reserve System (the “Federal Reserve Board”). We were organized on July 15, 1997, under the laws of the State of 
Michigan, primarily for the purpose of holding all of the stock of Mercantile Bank (“our bank”), and of such other subsidiaries as we may 
acquire or establish. Our bank commenced business on December 15, 1997. During the third quarter of 2013, we filed an election to become 
a financial holding company, which election became effective April 14, 2014. Mercantile Insurance Center, Inc. (“our insurance company”), 
a subsidiary of our bank, commenced operations during 2002 to offer insurance products. Mercantile Community Partners ("MCP"),
our subsidiary, began operations during 2023 to invest in community development tax credit investments. Our expenses have generally been 
paid using cash dividends from our bank. Our principal source of future operating funds is expected to be dividends from our bank.

Our Bank

Our bank is a state banking company that operates under the laws of the State of Michigan, pursuant to a charter issued by the

Michigan Department of Insurance and Financial Services. Our bank’s deposits are insured to the maximum extent permitted by law by the 
Federal Deposit Insurance Corporation (“FDIC”). Our bank, through its 43 office locations, provides commercial banking services primarily 
to small- to medium-sized businesses and retail banking services. Our bank’s main office is located in Grand Rapids, Michigan, and our 
operations are centered around the West and Central portions of Michigan. We also have banking offices located in the metropolitan Detroit, 
Michigan area, Traverse City, Michigan, Petoskey, Michigan, Saginaw, Michigan, and Midland, Michigan. Our bank makes secured and 
unsecured commercial, construction, mortgage and consumer loans, and accepts checking, savings and time deposits. Our bank owns 
11 automated teller machines ("ATM") and 33 video banking machines at a majority of our office locations that participate in the 
ACCEL/EXCHANGE and PLUS regional network systems, as well as other ATM networks throughout the country. Our bank also enables
customers to conduct certain loan and deposit transactions by personal computer and through mobile applications. Courier service is provided 
to certain commercial customers, and safe deposit boxes are available at a vast majority of our office locations. Our bank does not have trust 
powers.

Our Insurance Company

Our insurance company acquired an existing shelf insurance agency effective April 15, 2002. An Agency and Institution Agreement 

was entered into among our insurance company, our bank and Hub International for the purpose of providing programs of mass marketed 
personal lines of insurance. Insurance product offerings include private passenger automobile, homeowners, personal inland marine, boat 
owners, recreational vehicle, dwelling fire, umbrella policies, small business and life insurance products, all of which are provided by and 
written through companies that have appointed Hub International as their agent. To date, we have not provided the insurance products noted 
above and currently have no plans to do so.

Our Trusts

We have five business trusts that are wholly-owned subsidiaries of Mercantile Bank Corporation but are not consolidated. Each of 

the trusts was formed to issue preferred securities that were sold in private sales, as well as to sell common securities to Mercantile Bank 
Corporation. The proceeds from the preferred and common securities sales were used by the trusts to purchase floating rate notes issued by 
Mercantile Bank Corporation. The rates of interest, interest payment dates, call features and maturity dates of each floating rate note are 
identical to its respective preferred securities. The net proceeds from the issuance of the floating rate notes were used for a variety of 
purposes, including contributions to our bank as capital to provide support for asset growth and the funding of stock repurchase programs and 
certain acquisitions. The only significant assets of our trusts are the floating rate notes, and the only significant liabilities of our trusts are the 
preferred securities. The floating rate notes are categorized on our Consolidated Balance Sheets as subordinated debentures, and the interest 
expense is recorded on our Consolidated Statements of Income under interest expense on other borrowings.

Effect of Government Monetary Policies

Our earnings are affected by domestic economic conditions and the monetary and fiscal policies of the United States Government, 
its agencies, and the Federal Reserve Board. The Federal Reserve Board’s monetary policies have had, and will likely continue to have, an 
important impact on the operating results of commercial banks through its power to implement national monetary policy in order to, among 
other things, curb inflation, maintain or encourage employment, and mitigate economic recessions. The policies of the Federal Reserve Board 
have a major effect upon the levels of bank loans, investments and deposits through its open market operations in United States Government 
securities, and through its regulation of, among other things, the discount rate on borrowings of member banks. It is not possible to predict 
the nature and impact of future changes in monetary and fiscal policies.

Regulation and Supervision

Banks and bank holding companies, like many other financial institutions, are regulated under a variety of federal and state statutes 

and the regulations that implement those statutes. These statutes include, among others, the Dodd-Frank Wall Street Reform and Consumer 
Protection Act (the “Dodd-Frank Act”), the Economic Growth, Regulatory Relief, and Consumer Protection Act (“EGRRCPA”), the Truth in 
Lending Act, the Truth in Savings Act, the Equal Credit Opportunity Act, the Fair Credit Reporting Act, the Expedited Funds Availability 
Act, the Community Reinvestment Act, the Real Estate Settlement Procedures Act, the USA PATRIOT Act, the FACT Act, the Gramm-
Leach-Bliley Act, the Sarbanes Oxley Act, the Bank Secrecy Act, electronic funds transfer laws, redlining laws, predatory lending laws, 
antitrust laws, environmental laws, money laundering laws, privacy laws, state usury statutes, and statutes relating to fiduciaries. Our growth 
and earnings performance may be impacted by the statutes administered by, and the regulations and policies of, various governmental 
regulatory authorities. Those regulatory authorities include, but are not limited to, the Federal Reserve Board, the FDIC, the Michigan 
Department of Insurance and Financial Services, the Internal Revenue Service and state taxing authorities. The effect of such statutes, 
regulations and policies, and any changes thereto, may significantly impact our business which cannot necessarily be predicted.

As a registered bank holding company under the Bank Holding Company Act, we are required to file an annual report with the 

Federal Reserve Board and such additional information as the Federal Reserve Board may require. We are also subject to periodic
examinations by the Federal Reserve Board.

The Bank Holding Company Act limits the activities of bank holding companies to banking and the management of banking 

organizations and to certain permitted non-banking activities. The permitted non-banking activities generally include those limited activities 
that the Federal Reserve Board has determined, by order or regulation as of the day prior to enactment of the Gramm-Leach-Bliley Act, to be 
so closely related to banking as to be a proper incident to banking. These permitted non-banking activities include, among other things: 
operating a mortgage company, finance company, or factoring company; performing certain data processing operations; providing certain 
investment and financial advice; acting as an insurance agent for certain types of credit-related insurance; leasing property on a full-payout, 
nonoperating basis; and providing discount securities brokerage services for customers. Neither we nor any of our subsidiaries engage in any 
of the non-banking activities listed above.

On April 14, 2014, our election to become a financial holding company, as permitted by the Bank Holding Company Act, as 

amended by Title I of the Gramm-Leach-Bliley Act, was accepted and made effective by the Federal Reserve Board. In order to maintain our
status as a financial holding company, we and our bank must satisfy statutory requirements regarding capitalization, management and 
compliance with the Community Reinvestment Act. As a financial holding company, we are permitted to engage in a broader range of 
activities under the Bank Holding Company Act that are permitted for bank holding companies. Those expanded activities include any 
activity which the Federal Reserve Board (in certain instances in consultation with the Department of the Treasury) determines, by order or 
by regulation, to be financial in nature or incidental to such financial activity, or to be complementary to a financial activity, and not to pose a 
substantial risk to the safety and soundness of depository institutions or the financial system generally. Such expanded activities that have 
been previously approved by the Federal Reserve Board include, among others: insuring, guaranteeing, or indemnifying against loss, harm, 
damage, illness, disability or death, or issuing annuities, and acting as principal, agent or broker for such purposes; providing financial, 
investment or economic advisory services, including advising a mutual fund; and underwriting, dealing in, or making a market in securities. 
While our insurance company is permitted to engage in the insurance agency activities described above by virtue of our financial holding 
company status, neither we nor any of our subsidiaries currently engage in these expanded activities.

3

Our bank is subject to restrictions imposed by federal and state laws and regulations. Among other things, these restrictions limit the 

transactions our bank conducts with us, our other subsidiaries or other affiliates, limit our securities borrowing or lending, derivatives, and 
repurchase transactions with us, our other subsidiaries or other affiliates, limit investments in stock or other securities that we issue, limit the 
taking of such stock or securities as collateral for loans to any borrower, and limit acquisitions of assets or services from, and sales of certain 
types of assets to, us, our other subsidiaries or other affiliates. Michigan banking laws place additional restrictions on various aspects of 
banking, including branching, payment of dividends, and loan interest rates, in addition to capital and surplus requirements. Federal law 
restricts our ability to borrow from our bank by limiting the aggregate amount we may borrow and by requiring that all loans to us be secured 
in designated amounts by specified forms of collateral.

With respect to the acquisition of banking organizations, we are generally required to obtain the prior approval of the Federal
Reserve Board before we can acquire all or substantially all of the assets of any bank, or acquire ownership or control of any voting shares of 
any bank or bank holding company, if, after the acquisition, we would own or control more than 5% of the voting shares of the bank or bank 
holding company. Acquisitions of banking organizations across state lines are subject to additional restrictions imposed by federal and state 
laws and regulations.

The scope of regulations and supervision of various aspects of our business have expanded as a result of the adoption in July, 2010 
of the Dodd-Frank Act, and may continue to expand as the result of implementing regulations being adopted by federal regulators. However, 
on May 24, 2018, EGRRCPA amended certain provisions of the Dodd-Frank Act to tailor them to the specific circumstances of various 
categories of financial institutions and transactions. Many of the statutes and regulations under which we and our bank operate may change in 
the future, which may significantly impact our business.

Competition

We face substantial competition in all phases of our operations from a variety of different competitors. We compete for deposits, 
loans and other financial services with numerous Michigan-based and national and regional banks, savings banks, thrifts, credit unions and 
other financial institutions as well as with other entities that provide financial services. Some of the financial institutions and financial service 
organizations with whom we compete are not subject to the same degree of regulation as we are. Many of our primary competitors have been 
in business for many years, have established customer bases, are larger, have substantially higher lending limits than we do, and offer larger 
branch networks and other services which we do not. Most of these same entities have greater capital resources than we do, which, among 
other things, may allow them to price their services at levels more favorable to the customer and to provide larger credit facilities than we do. 
Under specified circumstances (that have been modified by the Dodd-Frank Act and EGRRCPA), securities firms and insurance companies 
that elect to become financial holding companies under the Bank Holding Company Act may acquire banks and other financial institutions. 
Federal and state banking law affects the competitive environment in which we conduct our business. The financial services industry is also 
likely to become more competitive as further technological advances enable more companies to provide financial services. We also face new 
competition as a result of expansion into new markets.

Human Capital

As of December 31, 2024, we employed 648 full-time and 34 part-time persons. Our human capital is the most valuable asset we 

have, and we believe embracing human diversity makes us a better financial institution. The collective sum of the individual differences, life 
experiences, knowledge, inventiveness, innovation, self-expression, unique capabilities and talent that our employees invest in their work 
represents a significant part of not only our culture, but our reputation and our achievements as well. We embrace and encourage our 
employees’ differences in age, color, disability, ethnicity, family or marital status, gender identity or expression, language, national origin, 
physical and mental ability, political affiliation, race, religion, sexual orientation, socio-economic status, veteran status and other 
characteristics that make our employees unique.

Talent Acquisition. We hire people who connect with, listen to and deliver the best solutions to customers and team 
members. Through a personalized and systematic recruiting process, our experienced team of Human Resources Business Partners are 
devoted to working with Hiring Managers and matching candidate skills and experience to a position where they can thrive. Hiring long-
term successful team members is critical to our success. We believe our successful hiring practices are reflected in our annual turnover rate 
of 10%, which is consistently below our peers.

4

Employee Safety and Health. The prioritization of our people is reflected in the robust employee benefits and compensation 

packages offered to our staff, including health and wellness insurance plans and incentives, a 401(k) plan with matching contributions, 
dedicated internship programs for young professionals in finance and business, and employee stock ownership plan participation, as well as 
clothing, home office and fitness equipment interest-free loans. Approximately 87% of our eligible employees participate in our medical 
benefit plans, which include a health savings account plan in which we pay the full monthly premiums. We offer our employees generous 
paid time off for vacations, holidays, sick time and bereavement, along with pay-it-forward initiatives and paid volunteer time. In addition, 
with obstacles in maintaining balance between work responsibilities and personal time, we have enabled staff to pursue a safe and healthy 
work-life balance by increasing paid time off benefits for our employees.

Climate Change

We define sustainability as the leveraging of combined abilities to ensure our ongoing impact on people and the environment, and 

our success is always focused on upholding long-lasting, positive results. From an efficient branch footprint to utilizing the latest technology, 
we are continuously focused on seeking new and better ways to be more productive with our time and energy while remaining good stewards 
of the resources with which we are entrusted. In each of our facilities, we follow LEED green certification guidelines wherever practical, 
evaluating all facilities for opportunities to incorporate energy efficient updates and space planning for new construction, renovations or 
expansion projects. All of our new construction and renovation projects include low-flow devices as well as LED lighting to enhance our 
efficiency of utility usage. Over the past five years, we have reduced our use of natural gas by 35% and electricity by 40%. All renovation 
and expansion projects involve the donation of former office furniture to non-profit organizations.

We continue to strive for the reduction of mail and paper usage through the promotion of customer eStatement adoption. The 

eStatement adoption rate continues to grow, and we were approaching above 61% adoption at year-end 2024. Our online accounts payable 
system has also enabled us to significantly reduce paper and printing, and saves time. Every effort is made to recycle all paper, and we 
continue to offer community paper shredding events. Additionally, we have implemented recycling stations at all of our office locations to 
divert cardboard, plastic and metal items from landfills. Water bottle refill stations also aid to reduce plastic bottle usage.

Our Sustainability Committee supports our ongoing commitment to environmental, health and safety, corporate social 

responsibility, corporate governance, sustainability, and other public policy matters relevant to our organization. The Sustainability 
Committee is a cross-functional management committee, with oversight from the Governance and Nominating Committee and the Board of 
Directors, that assists us in: (1) setting general strategies relating to ESG matters; (2) developing, implementing, and monitoring initiatives 
and policies based on those strategies; (3) recommending communications with employees, investors, and shareholders with respect to ESG 
matters; and (4) monitoring and assessing developments relating to, and improving our understanding of, ESG matters. The committee met 
three times during 2024. Highlights for 2024 included expanding the impact of Mercantile Community Partners LLC to facilitate low-income 
housing tax credits, completion and posting of the 2024 Corporate Sustainability Report, hiring a fulltime Director of Enterprise Excellence 
at the end of 2024 to oversee all ongoing ESG and sustainability efforts, implementation of a sustainability reporting platform, increased 
support of first-time home buyers mortgage programs, and over 27,500 hours of volunteering in the community completed by employees. 
Our bank maintains a Clawback Policy; an Insider Trading Policy; Code of Ethics; Corporate Governance Guidelines; an Anti-Bribery and 
Anti-Corruption Policy; an Anti-Money Laundering, Bank Secrecy Act, Customer Identification and Due Diligence Programs Letter; Vendor 
and Supplier Code of Conduct; Environmental Policy; Human Rights Policy; and Supplier Diversity Program Policy, which are reviewed and 
approved by our Board of Directors at least annually and can be found on our website.

Lending Policy

As a routine part of our business, we make loans to businesses and individuals located within our market areas. Our lending policy 

states that the function of the lending operation is twofold: to provide a means for the investment of funds at a profitable rate of return with an 
acceptable degree of risk, and to meet the credit needs of the creditworthy businesses and individuals who are our customers. We recognize 
that in the normal business of lending, some losses on loans will be inevitable and should be considered a part of the normal cost of doing 
business.

Our lending policy anticipates that priorities in extending loans will be modified from time to time as interest rates, market

conditions and competitive factors change. The policy sets forth guidelines on a nondiscriminatory basis for lending in accordance with 
applicable laws and regulations. The policy describes various criteria for granting loans, including the ability to pay; the character of the 
customer; evidence of financial responsibility; purpose of the loan; knowledge of collateral and its value; terms of repayment; source of 
repayment; payment history; and economic conditions.

The lending policy further limits the amount of funds that may be loaned against specified types of real estate collateral. For certain 

loans secured by real estate, the policy requires an appraisal of the property offered as collateral by a state-certified independent appraiser. 
The policy also provides general guidelines for loan to value for other types of collateral, such as accounts receivable and machinery and 
equipment. In addition, the policy provides general guidelines as to environmental analysis, loans to employees, executive officers and 
directors, problem loan identification, maintenance of an allowance for credit losses, loan review and grading, mortgage and consumer 
lending, and other matters relating to our lending practices.

The Board of Directors has delegated significant lending authority to officers of our bank. The Board of Directors believes this 

empowerment, supported by our strong credit culture and the significant experience of our commercial lending staff, enables us to be 
responsive to our customers. The loan policy specifies lending authority for our lending officers with amounts based on the experience level 
and ability of each lender. Our loan officers and loan managers are generally able to approve loans ranging from $0.25 million to $2.5 
million. We have established higher approval limits for our bank’s President and Chief Executive Officer and Chief Lending Officer, ranging 
from $4.0 million up to $10.0 million. These lending authorities, however, are typically used only in rare circumstances where timing is of 
the essence. Loan requests exceeding $5.0 million require approval by the Officers Loan Committee, and loan requests exceeding $15.0 
million, up to the legal lending limit of $101.4 million, require approval by our bank’s Board of Directors. We generally apply an in-house 
lending limit that is significantly less than our bank’s legal lending limit.

Lending Activity

Commercial Loans. Our commercial lending group originates commercial loans primarily in our market areas. Our commercial 
lenders have extensive commercial lending experience, with most having at least ten years’ experience. Loans are originated for general 
business purposes, including working capital, accounts receivable financing, machinery and equipment acquisition, and commercial real 
estate financing, including new construction and land development.

In most instances, commercial line of credit facilities have terms ranging from 12 to 24 months with floating rates tied to the Wall 

Street Journal Prime Rate or 30-Day Secured Overnight Funding Rate (“SOFR”). Commercial term loans secured by real estate are generally 
at a floating rate tied to the Wall Street Journal Prime Rate or 30-Day SOFR. Since the fourth quarter of 2020, a fixed rate option for 
commercial term loans secured by real estate is generally not offered for loans over $2.5 million; instead, customers are offered participation 
in our back-to-back interest rate swap program to achieve a desired fixed rate. For loans under $2.5 million, we offer a rate primarily equal to 
the commensurate cost of funds using Federal Home Loan Bank of Indianapolis (“FHLBI”) advance rates as a proxy and a credit spread as 
indicated by the credit rating we assign. Commercial term loans secured by real estate generally balloon within five years, with payments 
based on amortizations ranging from 10 to 25 years. Commercial term loans secured by non-real estate collateral are generally at a floating 
rate tied to the Wall Street Journal Prime Rate or 30-Day SOFR, or a fixed rate primarily equal to the commensurate cost of funds using 
FHLBI advance rates as a proxy and a credit spread as indicated by the credit rating we assign, and generally mature and fully amortize 
within three to seven years.

We evaluate many aspects of a commercial loan transaction in order to minimize credit and interest rate risk. Underwriting includes 
an assessment of the management, products, markets, cash flow, capital, income and collateral of the borrowing entity. This analysis includes 
a review of the borrower’s historical and projected financial results. Appraisals are generally required to be performed by state-certified 
independent appraisers where real estate is the primary collateral, and in some cases, where equipment is the primary collateral. In certain 
situations, for creditworthy customers, we may accept title reports instead of requiring lenders’ policies of title insurance.

We have no material foreign loans, and only limited exposure to companies engaged in energy producing and agricultural-related 

activities.

Commercial Real Estate loans. Commercial real estate loans, consisting of non-owner occupied, owner occupied, multi-family and 

residential rental, and vacant land, land development, and residential construction loans, totaled 52.6% and 50.2% of our total loans as 
of December 31, 2024 and 2023, respectively. We also adhere to the FDIC’s commercial real estate lending concentration guidelines 
specified in the Joint Guidance on Concentrations in Commercial Real Estate Lending, Sound Risk Management Practices. Total 
commercial real estate loans (as defined in the guidance) represented 256% and 247% of total regulatory capital as of December 31, 2024 and 
2023, respectively, with both ratios being below the maximum guideline of 300%.

Commercial real estate lending involves more risk than residential lending because loan balances are typically greater and 

repayment is dependent upon the borrower’s business operations. We attempt to minimize the risks associated with these transactions by
generally limiting our commercial real estate lending to owner operated properties and to owners of non-owner occupied properties who have 
established profitable histories and satisfactory tenant structures. In many cases, risk is further reduced by requiring personal guarantees, 
limiting the amount of credit to any one borrower to an amount considerably less than our legal lending limit and avoiding certain types of 
commercial real estate financings.

Risks of repayment can arise from general downward shifts in the valuations of specific property types often driven by changes in 
demand and other economic factors, which could further influence cash flows associated with the borrower and/or the underlying property. 
To mitigate these risks, we actively monitor market conditions in the markets we originate loans. The majority of our commercial real estate 
portfolio is located within our primary geographic footprint within the state of Michigan. As of December 31, 2024 and 2023, 90.7% and 
90.3%, respectively, of our commercial real estate loans were for projects located within the state of Michigan. Loans made outside the state 
of Michigan are usually to customers located or headquartered within our footprint doing business in other states.

Single-Family Residential Real Estate Loans. We originate single-family residential real estate loans in our market areas, generally 

according to secondary market underwriting standards. Loans not conforming to those standards are made in certain circumstances. Single-
family residential real estate loans provide borrowers with a fixed or adjustable interest rate with terms up to 30 years, with the fixed interest 
rate loans generally sold to various investors.

Consumer Loans. We originate various types of consumer loans, including new and used automobile and boat loans, credit cards 

and overdraft protection lines of credit for our checking account customers. Consumer loans generally have shorter terms and higher interest 
rates and usually involve more credit risk than single-family residential real estate loans because of the type and nature of the collateral. Our 
bank has a home equity line of credit program. Home equity lines of credit are generally secured by either a first or second mortgage on the 
borrower’s primary residence. The program provides revolving credit at a rate tied to the Wall Street Journal Prime Rate.

We believe our consumer loans are underwritten carefully, with a strong emphasis on the amount of the down payment, credit 

quality, employment stability and monthly income of the borrower. These loans are generally repaid on a monthly repayment schedule with 
the source of repayment tied to the borrower’s periodic income. In addition, consumer lending collections are dependent on the borrower’s 
continuing financial stability, and are thus likely to be adversely affected by job loss, illness and personal bankruptcy. In many cases, 
repossessed collateral for a defaulted consumer loan will not provide an adequate source of repayment of the outstanding loan balance 
because of depreciation of the underlying collateral. We believe that the generally higher yields earned on consumer loans compensate for the 
increased credit risk associated with such loans, and that consumer loans are important to our efforts to serve the credit needs of the 
communities and customers that we serve.

Loan Portfolio Quality

We utilize a comprehensive grading system for our commercial loans, whereby all commercial loans are graded on a ten grade 
rating system. The rating system utilizes standardized grade paradigms that analyze several critical factors such as cash flow, operating 
performance, financial condition, collateral, industry condition and management. All commercial loans are graded at inception and reviewed 
at various intervals.

Our independent loan review program is primarily responsible for the administration of the grading system and ensuring adherence 

to established lending policies and procedures. The loan review program is an integral part of maintaining our strong asset quality culture. 
The loan review function works closely with senior management, although it functionally reports to the Board of Directors. Using a risk-
based approach to selecting credits for review, our loan review program covered approximately 69% of total commercial loans outstanding 
during 2024. In addition, a random sampling of retail loans is reviewed each quarter. Our watch list credits are reviewed monthly by our 
Board of Directors and our Watch List Committee, the latter of which is comprised of senior level officers from the administration, lending 
and loan review functions.

Loans are placed in a nonaccrual status when, in our opinion, uncertainty exists as to the ultimate collection of all principal and 

interest. As of December 31, 2024, loans placed in nonaccrual status totaled $5.7 million, or 0.1% of total loans, compared to $3.4 million, or 
0.1% of total loans, at December 31, 2023. We had no loans past due 90 days or more and still accruing interest at year-end 2024 or 2023.

Additional information relative to the loan portfolio is incorporated by reference to Management’s Discussion and Analysis of 

Financial Condition and Results of Operations (“Management’s Discussion and Analysis”) and Note 3 of the Notes to Consolidated Financial 
Statements in this Annual Report.

Allowance for Credit Losses

The allowance is maintained at a level we believe is adequate to absorb estimated credit losses identified and expected in the loan 

portfolio. Our evaluation of the adequacy of the allowance is an estimate based on past loan loss experience, the nature and volume of the 
loan portfolio, information about specific borrower situations and estimated collateral values, guidance from bank regulatory agencies, and 
assessments of the impact of current and anticipated economic conditions on the loan portfolio. Allocations of the allowance may be made for 
specific loans, but the entire allowance is available for any loan that, in our judgment, should be charged-off. Credit losses are charged 
against the allowance when we believe the uncollectibility of a loan is likely. The balance of the allowance represents our best estimate, but 
significant downturns in circumstances relating to loan quality or economic conditions could result in a requirement for an increased 
allowance in the future. Likewise, an upturn in loan quality or improved economic conditions may result in a decline in the required 
allowance in the future. In either instance, unanticipated changes could have a significant impact on the allowance and operating results. The 
allowance is increased through a provision charged to operating expense. Uncollectible loans are charged-off through the allowance, while 
recoveries of loans previously charged-off are added to the allowance.

Additional detail regarding the allowance is incorporated by reference to Management’s Discussion and Analysis and Note 3 of the 

Notes to Consolidated Financial Statements included in this Annual Report.

Investments

Bank Holding Company Investments. The principal investments of our bank holding company are the investments in the common 

stock of our bank, the common securities of our trusts, and the community development tax credit investments made by MCP. Other funds of 
our bank holding company may be invested from time to time in various debt instruments.

Subject to the limitations of the Bank Holding Company Act, we are also permitted to make portfolio investments in equity 

securities and to make equity investments in subsidiaries engaged in a variety of non-banking activities, which include real estate-related 
activities such as community development, real estate appraisals, arranging equity financing for commercial real estate, and owning and 
operating real estate used substantially by our bank or acquired for its future use. MCP invests as a limited liability member in real estate 
entities engaged in community development. Our bank holding company has no plans at this time to make directly any other types of equity 
investments at the bank holding company level. Our Board of Directors may, however, alter the investment policy at any time without 
shareholder approval.

Our Bank’s Investments. Our bank may invest its funds in a wide variety of debt instruments and may participate in the federal 
funds market with other depository institutions. Subject to certain exceptions, our bank is prohibited from investing in equity securities. 
Among the equity investments permitted for our bank under various conditions and subject in some instances to amount limitations, are 
shares of a subsidiary insurance agency, mortgage company, real estate company, or Michigan business and industrial development company, 
such as our insurance company. Under another such exception, in certain circumstances and with prior notice to or approval of the FDIC, our 
bank could invest up to 10% of its total assets in the equity securities of a subsidiary corporation engaged in the acquisition and development 
of real property for sale or the improvement of real property by construction or rehabilitation of residential or commercial units for sale or 
lease. Our bank has no present plans to make such an investment. Real estate acquired by our bank in satisfaction of or foreclosure upon 
loans may be held by our bank for specified periods. Our bank is also permitted to invest in such real estate as is necessary for the convenient 
transaction of its business. Our bank’s Board of Directors may alter our bank’s investment policy without shareholder approval at any time.

Additional detail and information relative to the securities portfolio is incorporated by reference to Management’s Discussion and 

Analysis and Note 2 of the Notes to Consolidated Financial Statements included in this Annual Report.

Item 1A. Risk Factors.

The following risk factors could affect our business, financial condition or results of operations. These risk factors should be 
considered in connection with evaluating the forward-looking statements contained in this Annual Report because they could cause the actual 
results and conditions to differ materially from those projected in forward-looking statements. Before you buy our common stock, you should 
know that investing in our common stock involves risks, including the risks described below. The risks that are highlighted here are not the 
only ones we face. If the adverse matters referred to in any of the risks actually occur, our business, financial condition or operations could be 
adversely affected. In that case, the trading price of our common stock could decline, and you may lose all or part of your investment.

Risks Related to Our Business

We are subject to interest rate risk.

Our earnings and cash flows are largely dependent upon our net interest income. Interest rates are highly sensitive to many factors 

that are beyond our control, including general economic conditions and policies of various governmental and regulatory agencies and, in 
particular, the Federal Reserve Board. Generally speaking, increases in the targeted federal funds rate positively impact our net interest 
income. In contrast, higher interest rates generally have a negative impact on both the housing market, by reducing refinancing activity and 
new home purchases, and the U.S. economy.

We principally manage interest rate risk by managing the volume and mix of our earning assets and funding liabilities. Changes in 

monetary policy, including changes in interest rates, could influence not only the interest we receive on loans and investments and the 
amount of interest we pay on deposits and borrowings, but these changes could also affect: (1) our ability to originate and/or sell loans and 
obtain deposits; (2) the fair value of our financial assets and liabilities, which could negatively impact shareholders’ equity, and our ability to 
realize gains from the sale of such assets; (3) our ability to obtain and retain deposits in competition with other available investment 
alternatives; (4) the ability of our borrowers to repay adjustable or variable rate loans; and (5) the average duration of our investment 
securities portfolio and other interest-earning assets. If the interest rates paid on deposits and borrowings increase at a faster rate than the 
interest received on loans and other investments, our net interest income, and therefore earnings, could be adversely affected. Earnings could 
also be adversely affected if the interest rates received on loans and other investments decline more rapidly than the interest rates paid on 
deposits and other borrowings. In a changing interest rate environment, we may not be able to manage this risk effectively. If we are unable 
to manage interest rate risk effectively, our business, financial condition and results of operations could be materially affected.

We are subject to liquidity risk. 

Our banking operations require liquidity to meet our deposit and debt obligations as they come due. There are many potential 

factors that could reduce our access to liquidity sources, including higher interest rate environments, tightening fiscal policy, a downturn in 
the U.S. economy, difficult credit markets or adverse regulatory actions. Our access to deposits may also be affected by the liquidity needs of 
our depositors. A substantial majority of our liabilities are demand, savings, interest checking and money market deposits, which are payable 
on demand or upon several days' notice, while by comparison, a substantial portion of our assets are loans, which cannot be called or sold in 
the same time frame. We may not be able to replace maturing deposits and advances as necessary in the future, especially if a large number of 
our depositors sought to withdraw their accounts, regardless of the reason. Our access to deposits may be negatively impacted by, among 
other factors, periods of low interest rates or higher interest rates which could promote increased competition for deposits, including from 
new financial technology competitors, or provide customers with alternative investment options. Additionally, negative news about us or the 
banking industry in general could negatively impact market and/or customer perceptions of our company, which could lead to a loss of 
depositor confidence and an increase in deposit withdrawals, particularly among those with uninsured deposits. Furthermore, as we and other 
regional banking organizations experienced in 2023, the failure of other financial institutions may cause deposit outflows as customers spread 
deposits among several different banks so as to maximize their amount of FDIC insurance, move deposits to banks deemed "too big to fail" 
or remove deposits from the banking system entirely. As of December 31, 2024, approximately 54% of our deposits were uninsured, and we 
rely on these deposits for liquidity. A failure to maintain adequate liquidity could have a material adverse effect on our business, financial 
condition and results of operations.

10

Unfavorable economic, geopolitical conflicts and other political conditions could adversely affect our business, financial condition or 
results of operations.

Our results of operations could be adversely affected by general conditions in the local, national, and global economies, financial 

markets and political conditions. Our financial performance generally, and in particular the ability of borrowers to pay interest on and repay 
principal of outstanding loans and the value of collateral securing those loans, as well as demand for loans and other products and services we 
offer, is highly dependent upon the business environment in the markets where we operate. A favorable business environment is generally 
characterized by, among other factors, economic growth, efficient capital markets, low inflation, low unemployment, high business and 
investor confidence, and strong business earnings. Unfavorable or uncertain economic and market conditions can be caused by a decline in 
economic growth both in the U.S. and internationally; declines in business activity or investor or business confidence; limitations on the 
availability of or increases in the cost of credit and capital; increases in inflation or interest rates; high unemployment; natural disasters; 
global pandemics, trade policies and tariffs; or a combination of these or other factors. In addition, financial markets and global supply chains 
may be adversely affected by the current or anticipated impact of global wars/military conflicts, terrorism or other geopolitical events. A
weak or declining economy or political disruption, including any international trade disputes, could also strain our manufacturers or 
suppliers, possibly resulting in supply disruptions, or cause our customers to delay making payments for our products and services. Any of 
the foregoing could seriously harm our business, and we cannot anticipate all of the ways in which the political or economic climate and 
financial market conditions could seriously harm our business.

Significant declines in the value of commercial real estate could adversely impact us.

Approximately 63% of our total commercial loans, or about 52% of our total loans, relate to commercial real estate. Commercial 
real estate lending involves more risk than residential lending because loan balances are typically greater and repayment is dependent upon 
the borrower’s business operations. Stressed economic conditions may reduce the value of commercial real estate and strain the financial 
conditions of our commercial real estate borrowers, especially in the land development and non-owner occupied commercial real estate 
segments of our loan portfolio. Those difficulties could adversely affect us and could produce losses and other adverse effects on our 
business. Additionally, in recent years, commercial real estate markets have been particularly impacted by the economic disruption resulting 
from the COVID-19 pandemic. The COVID-19 pandemic has also been a catalyst for the evolution of various remote work options that have 
impacted the long-term performance of some types of office properties within our commercial real estate portfolio. Accordingly, the federal 
banking regulatory agencies have expressed concerns about weaknesses in the current commercial real estate market. Failures in our risk 
management policies, procedures and controls could adversely affect our ability to manage this portfolio going forward and could result in an 
increased rate of delinquencies in, and increased losses from, this portfolio, which, accordingly, could have a material adverse effect on our 
business, financial condition and results of operations.

Market volatility may adversely affect us. 

The capital and credit markets may experience volatility and disruption. In some cases, the markets have produced downward 
pressure on stock prices and credit availability for certain issuers without apparent regard to those issuers’ underlying financial strength. 
Future levels of market disruption and volatility may have an adverse effect, which may be material, on our ability to access capital and on 
our business, financial condition and results of operations.

Our future success is dependent on our ability to compete effectively in the highly competitive banking industry.

We face substantial competition in all phases of our operations from a variety of different competitors. Our future growth and

success will depend on our ability to compete effectively in this highly competitive environment. We compete for deposits, loans and other 
financial services with numerous Michigan-based and national and regional banks, thrifts, credit unions and other financial institutions as 
well as other entities that provide financial services, including securities firms and mutual funds. Some of the financial institutions and 
financial service organizations with which we compete are not subject to the same degree of regulation as we are. Many of our competitors 
have been in business for many years, have established customer bases, are larger, have substantially higher lending limits than we do and 
offer larger branch networks and other services which we do not, including trust and international banking services. Most of these entities 
have greater capital and other resources than we do, which, among other things, may allow them to price their services at levels more
favorable to the customer and to provide larger credit facilities than we do. This competition may limit our growth or earnings. Under 
specified circumstances (that have been modified by the Dodd-Frank Act and EGRRCPA), securities firms and insurance companies that 
elect to become financial holding companies under the Bank Holding Company Act may acquire banks and other financial institutions. 
Federal banking law affects the competitive environment in which we conduct our business. The financial services industry is also likely to 
become more competitive as further technological advances enable more companies to provide financial services. These technological 
advances may diminish the importance of depository institutions and other financial intermediaries in the transfer of funds between parties.

Our risk management systems may fall short of their intended objectives.

We seek to monitor and control our risk exposure through a risk and control framework encompassing a variety of separate but 

complementary financial, credit, operational, compliance and legal reporting systems, internal controls, management review processes and 
other mechanisms. Our risk management process seeks to balance our ability to profit from investing or lending positions with our exposure 
to potential losses. While we employ a broad and diversified set of risk monitoring and risk mitigation techniques, those techniques and the 
judgments that accompany their application cannot anticipate every economic and financial outcome or the specifics and timing of such 
outcomes. Thus, we may, in the course of our activities, incur losses.

11

We may not be able to successfully adapt to evolving industry standards and market pressures.

Our success depends, in part, on our ability to adapt products and services to evolving industry standards. There is increasing
pressure to provide products and services at lower prices. This can reduce net interest income and noninterest income from fee-based 
products and services. In addition, the widespread adoption of new technologies could require us to make substantial capital expenditures to 
modify or adapt existing products and services or develop new products and services. We may not be successful in introducing new products 
and services in response to industry trends or developments in technology, or those new products may not achieve market acceptance. As a 
result, we could lose business, be forced to price products and services on less advantageous terms to retain or attract clients, or be subject to 
cost increases. As a result, our business, financial condition, or results of operations may be adversely affected.

Our inability to execute or integrate potential future acquisitions successfully could impede us from realizing all of the benefits of the 
acquisitions, which could weaken our operations.

In addition to pursuing organic growth, we may also pursue strategic acquisition opportunities that we believe will fit our core

philosophy and culture, enhance our profitability and provide appropriate risk-adjusted returns. These acquisition opportunities could be 
material to our business and involve a number of risks, including the following:

° intense competition from other banking organizations and other acquirers for potential merger candidates drives market pricing;
° time and expense associated with identifying and evaluating potential acquisitions and negotiating potential transactions may 

divert human and capital resources without producing the desired returns;

° estimates and judgments used to evaluate credit, operations, management and market risks with respect to the target institution 

or assets are inherently complex and may be inaccurate;

° potential exposure to unknown or contingent liabilities of targets; and
° regulatory time frames for review of applications may limit the number and frequency of transactions we may be able to 

consummate.

If we are unable to successfully integrate potential future acquisitions, we could be impeded from realizing all of the benefits of 

those acquisitions and could weaken our business operations. The integration process may disrupt our business and, if implemented 
ineffectively, may preclude realization of the full benefits expected by us and could harm our results of operations. In addition, the overall 
integration of the combining companies may result in unanticipated problems, expenses, liabilities and competitive responses, and may cause 
our stock price to decline. The difficulties of integrating an acquisition include, among others:

° unanticipated issues in integration of information, communications and other systems;
° unanticipated incompatibility of logistics, marketing and administrative methods;
° maintaining employee morale and retaining key employees;
° integrating the business cultures of both companies;
° preserving important strategic client relationships;
° coordinating geographically diverse organizations; and
° consolidating corporate and administrative infrastructures and eliminating duplicative operations.

Finally, even if the operations of an acquisition are integrated successfully, we may not realize the full benefits of the acquisition, 

including the synergies, cost savings or growth opportunities we expect. These benefits may not be achieved within the anticipated time 
frame as well.

Our inability to overcome these risks could have an adverse effect on our ability to implement our business strategy, which, in turn, 

could have an adverse effect on our business, financial condition and results of operations.

The soundness of other financial institutions could adversely affect us. 

Our ability to engage in routine funding transactions could be adversely affected by the actions and commercial soundness of other 

financial institutions. Financial services institutions are interrelated as a result of trading, clearing, counterparty or other relationships. We 
have exposure to many different industries and counterparties, and we routinely execute transactions with counterparties in the financial 
industry. As a result, defaults by, or even rumors or questions about, one or more financial services institutions, or the financial services 
industry generally, have led to market-wide liquidity problems and could lead to losses or defaults by us or by other institutions. Even routine 
funding transactions expose us to credit risk in the event of default of our counterparty or client. In addition, our credit risk may be 
exacerbated when the collateral held by us cannot be realized upon or is liquidated at prices not sufficient to recover the full amount of the 
financial instrument exposure due us. There is no assurance that any such losses would not materially and adversely affect our results of 
operations.

12

Our credit losses could increase and our allowance may not be adequate to cover actual loan losses.

As the risk of nonpayment of loans is inherent in all lending activities, we maintain allowances for credit losses on loans, securities 

and off-balance sheet credit exposures. Regardless, nonpayment, when it occurs, may have a materially adverse effect on our earnings and 
overall financial condition as well as the value of our common stock. Our focus on commercial lending may result in a larger concentration of 
loans to small businesses. As a result, we may assume different or greater lending risks than other banks. We make various assumptions and 
judgments about the collectibility of our loan portfolio and provide an allowance for credit losses based on several factors. If our assumptions 
are wrong, our allowance may not be sufficient to cover our losses, which would have an adverse effect on our operating results. The actual 
amounts of future provisions for credit losses cannot be determined at this time and may exceed the amounts of past provisions. Any increase 
in the allowance for credit losses on loans, securities and/or off-balance sheet credit exposures will result in a decrease in net income and, 
possibly, capital, and may have a material adverse effect on our business, financial condition and results of operations.

We rely heavily on our management and other key personnel, and the loss of any of them may adversely affect our operations.

We are and will continue to be dependent upon the services of our management team, including our executive officers and our other 

senior managers. The unanticipated loss of our executive officers, or any of our other senior managers, could have an adverse effect on our 
growth and performance.

In addition, we continue to depend on our key commercial loan officers. Several of our commercial loan officers are responsible, or 

share responsibility, for generating and managing a significant portion of our commercial loan portfolio. Our success can be attributed in 
large part to the relationships these officers as well as members of our management team have developed and are able to maintain with our 
customers as we continue to implement our community banking philosophy. The loss of any of these commercial loan officers could 
adversely affect our loan portfolio and performance, and our ability to generate new loans. Many of our key employees have signed 
agreements with us agreeing not to compete with us in one or more of our markets for specified time periods if they leave employment with 
us. However, we may not be able to effectively enforce such agreements.

Some of the other financial institutions in our markets also require their key employees to sign agreements that preclude or limit 
their ability to leave their employment and compete with them or solicit their customers. These agreements make it more difficult for us to 
hire loan officers with experience in our markets who can immediately solicit their former or new customers on our behalf.

Direct and indirect effects of climate change may adversely affect us.

Climate change presents immediate and long-term risks to us and to our customers and communities, with risks expected to increase 

over time. Climate change refers to risk of life and property damage occurring due to naturally occurring events induced by human behavior 
and can manifest in the form of physical risk and indirect risk. Physical risk refers to results of severe weather, such as floods, hurricanes, 
rising sea levels, fires and water availability. Indirect risk refers to how changes in regulation, conscious consumer choices, competition for 
sustainable products, and reduced demand for goods or services that produce significant green-house gas emissions may impact the results 
and operations of a company. Physical effects of climate change to our offices, branches or personnel could have an immediate adverse effect 
on our operations and financial condition, whereas indirect consequences may result in increased expenditures to comply with climate-related 
regulations.

Similarly, physical effects could have a severe impact on the business and operations of our customers and vendors. Furthermore, 
consumer choices and shareholder demands could require our customers to invest more in cleaner energy manufacturing and procurement 
and to compete with innovative new products that generate lower emissions, which may or may not be successful. If our customers are not 
able to keep up with evolving climate change effects, it could ultimately have an adverse effect on our business and results of operations. 
Lastly, like other financial institutions, we also run a reputational risk of financing businesses that are responsible for significant green-house 
gas emissions or are related to carbon-based energy sources. While our risk management framework monitors various types of risks and 
applies risk mitigation techniques including for environmental risks, and while we have been conscious of our own carbon footprint and have 
established a Sustainability Committee, introduction of new climate-related legislation and related compliance costs as well as the 
unpredictable effects of climate change on us or our customers could have a negative impact on our business, financial condition and results 
of operations, even if temporary in nature.

13

Failure to meet the rapidly changing ESG expectations or standards, or achieve our ESG goals, could adversely affect our business, 
results of operations, financial condition or stock price.

There are rapidly changing discussions and regulations surrounding ESG matters, including greenhouse gas emissions, 

sustainability and climate-related risks; diversity, equity and inclusion; responsible sourcing and supply chain; human rights and social 
responsibility; and corporate governance and oversight. Given our commitment to ESG, we actively manage these issues and have 
established and publicly announced certain goals, commitments and targets which we may refine or even expand further in the future. These 
goals, commitments and targets reflect our current plans and aspirations and are not guarantees that we will be able to achieve them. Evolving 
stakeholder expectations and our efforts and ability to manage these issues, provide updates on them and accomplish our goals, commitments 
and targets present numerous operational, regulatory, reputational, financial, legal and other risks, any of which may be outside of our control 
or could have a material adverse impact on our business, including on our reputation and stock price. Further, there is uncertainty around the 
accounting standards and climate-related disclosures associated with emerging laws and reporting requirements and the related costs to 
comply with the emerging regulations.

Changes in SOFR could adversely affect the amount of interest that accrues on SOFR-linked instruments.

Effective January 1, 2022, we replaced the 30-Day Libor Rate with the CME Term SOFR Rate for all new floating rate commercial 
loan commitments. On or about June 30, 2023, all commercial loans tied to the 30-Day Libor Rate converted to an equivalent fallback SOFR 
Rate. Because SOFR is published by the Federal Reserve Bank of New York ("FRBNY") based on data received from other sources, we have 
no control over its determination, calculation or publication. There can be no assurance that SOFR will not be discontinued or fundamentally 
altered in a manner that is materially adverse to the interests of investors in SOFR-linked instruments. If the manner in which SOFR is 
calculated is changed, that change may result in a change in the amount of interest that accrues on the SOFR-linked instruments. In addition, 
the interest rate on SOFR-linked instruments may for any day not be adjusted for any modification or amendments to SOFR for that day that 
the FRBNY may publish if the interest rate for that day has already been determined prior to such determination. There is no assurance that 
changes in SOFR could not have a material adverse effect on the yield on, value of, and market for SOFR-linked instruments, which could 
have a material adverse effect on our business.

Further, SOFR is a relatively new interest rate, and the FRBNY or any successor, as administrator of SOFR, may make 
methodological or other changes that could change the value of SOFR, including changes related to the methodology by which SOFR is 
calculated, eligibility criteria applicable to the transactions used to calculate SOFR or timing related to the publication of SOFR. If the 
manner in which SOFR is calculated is changed, the change may result in a reduction of the amount of interest payable on loans we have 
made to customers, which could have a material adverse effect on our business. The administrator of SOFR may withdraw, modify, suspend 
or discontinue the calculation or dissemination of SOFR in its sole discretion and without notice, and has no obligation to consider the 
interests of investors in calculating, withdrawing, modifying, amending, suspending or discontinuing SOFR.

Our accounting policies and methods are the basis for how we prepare our consolidated financial statements, and they require 
management to make estimates about matters that are inherently uncertain.

Accounting policies and processes are fundamental to how we record and report our financial condition and results of operations. 
We must exercise judgment in selecting and applying many of these accounting policies and processes so they comply with U.S. GAAP. In 
some cases, we must select the accounting policy or method to apply from two or more alternatives, any of which may be reasonable under 
the circumstances, yet may result in our reporting materially different results than would have been reported under a different alternative.

We have identified certain accounting policies as being critical because they require us to make difficult, subjective or complex 

judgments about matters that are uncertain. Materially different amounts could be reported under different conditions or using different 
assumptions or estimates. We have established detailed policies and control procedures that are intended to ensure these critical accounting 
estimates and judgments are well controlled and applied consistently. In addition, the policies and procedures are intended to ensure that the 
process for changing methodologies occurs in an appropriate manner. Because of the uncertainty surrounding management’s judgments and 
the estimates pertaining to these matters, we cannot guarantee that we will not be required to adjust accounting policies or restate prior period 
financial statements. For additional information, see “Critical Accounting Estimates” beginning on page F-3 of this Annual Report and “Note 
1 – Summary of Significant Accounting Policies” beginning on page F-36 of this Annual Report.

We continually encounter technological change, and we may have fewer resources than our competitors to continue to invest in 
technological improvements.

The banking industry is undergoing technological changes with frequent introductions of new technology-driven products and 

services, such as those related to artificial intelligence, automation and algorithms. In addition to better serving customers, the effective use of 
technology increases efficiency and enables financial institutions to reduce costs. Our future success will depend, in part, on our ability to 
address the needs of our customers by using technology to provide products and services that will satisfy customer demands for convenience 
as well as create additional efficiencies in our operations. Many of our competitors have substantially greater resources to invest in 
technological improvements than we do. There can be no assurance that we will be able to effectively implement new technology-driven 
products and services or be successful in marketing these products and services to our customers. In addition, our implementation of certain 
new technologies, such as those related to artificial intelligence, automation and algorithms, in our business processes may have unintended 
consequences due to their limitations or our failure to use them effectively. Failure to successfully manage technological changes could have 
a material adverse effect on our business, financial condition and results of operations.

Damage to our reputation could materially harm our business.

Our relationship with many of our clients is predicated upon our reputation as a fiduciary and a service provider that adheres to the 
highest standards of ethics, service quality and regulatory compliance. Adverse publicity, regulatory actions, litigation, operational failures, 
the failure to meet client expectations and other issues with respect to one or more of our businesses could materially and adversely affect our 
reputation, our ability to attract and retain clients or our sources of funding for the same or other businesses. Preserving and enhancing our 
reputation also depends on maintaining systems and procedures that address known risks and regulatory requirements, as well as our ability 
to identify and mitigate additional risks that arise due to changes in our businesses and the marketplaces in which we operate, the regulatory 
environment and client expectations. If any of these developments has a material effect on our reputation, our business will suffer.

Our business is subject to operational risks.

We, like most financial institutions, are exposed to many types of operational risks, including the risk of fraud by employees or 

outsiders, unauthorized transactions by employees or operational errors. To date, we have not experienced a significant compromise, 
significant data loss or any material financial losses related to cybersecurity attacks, but our systems and those of our customers and third-
party service providers are under constant threat, and it is possible that we could experience a significant event in the future. Operational 
errors may include clerical or record keeping errors or those resulting from faulty or disabled computer or telecommunications systems. 
Given our volume of transactions, certain errors may be repeated or compounded before they are discovered and successfully corrected. Our 
necessary dependence upon automated systems to record and process our transaction volume may further increase the risk that technical 
system flaws or employee tampering or manipulation of those systems will result in losses that are difficult to detect.

We may also be subject to disruptions of our operating systems arising from events that are wholly or partially beyond our control, 
including, for example, computer viruses or electrical or telecommunications outages, which may give rise to losses in service to customers 
and to loss or liability to us. We are further exposed to the risk that our external vendors may be unable to fulfill their contractual obligations 
to us, or will be subject to the same risk of fraud or operational errors by their respective employees as are we, and to the risk that our or our 
vendors’ business continuity and data security systems prove not to be adequate. We also face the risk that the design of our controls and 
procedures proves inadequate or is circumvented, causing delays in detection or errors in information. Although we maintain a system of 
controls designed to keep operational risks at appropriate levels, there can be no assurance that we will not suffer losses from operational 
risks in the future that may be material in amount.

15

We face the risk of cyber-attack to our computer systems.

In the ordinary course of business, we collect and store sensitive data, including proprietary business information and personally 
identifiable information of our customers and employees in systems and on networks. The secure processing, maintenance and use of this 
information is critical to our operations. To date, we have not experienced a significant compromise, significant data loss or any material 
financial losses related to cybersecurity attacks, but our systems and those of our customers and third-party service providers are under 
constant threat, and it is possible that we could experience a significant event in the future. Cybersecurity threats include unauthorized access, 
loss or destruction of data (including confidential client information), account takeovers, unavailability of service, computer viruses or other 
malicious code, cyber-attacks and other events. Remote working of employees introduces additional potential cybersecurity risks due to the 
use of home networks, video conferencing and other remote work technologies over which we do not have as much control as our internal 
systems.

Cyber threats may derive from human error, fraud or malice on the part of employees or third parties, or may result from accidental 

technological failure. We cannot assure that such breaches, failures or interruptions will not occur or, if they do occur, that they will be 
adequately addressed by us or the third parties on which we rely. We may not be insured against all types of losses as a result of third-party 
failures, and insurance coverage may be inadequate to cover all losses resulting from breaches, systems failures or other disruptions. If one or 
more of these events occurs, it could result in the disclosure of confidential client information, damage to our reputation with our clients and 
the market, additional costs to us (such as repairing systems or adding new personnel or protection technologies), regulatory penalties and 
financial losses, to both us and our clients and customers. Such events could also cause interruptions or malfunctions in our operations (such 
as the lack of availability of our online banking system), as well as the operations of our clients, customers or other third parties. Risks and 
exposures related to cybersecurity attacks are expected to remain high for the foreseeable future due to the rapidly evolving nature and 
sophistication of these threats, as well as due to the expanding use of internet banking, mobile banking and other technology-based products 
and services by us and our customers. Although we maintain safeguards to protect against these risks, there can be no assurance that we will 
not suffer losses in the future that may be material in amount.

Cybersecurity risks and disclosures are increasingly regulated by various government agencies, including federal and state bank 

regulatory agencies and the Securities and Exchange Commission. Failure to observe such guidance may result in supervisory identification 
of unsafe or unsound practices or other deficiencies in risk management or other areas that do not constitute violations of law or regulation.

Regulatory Risks

We are subject to significant government regulation, and any regulatory changes may adversely affect us.

The banking industry is subject to extensive regulation, supervision and legal requirements under both federal and state law that 

govern almost all aspects of our operations. These regulations are primarily intended to protect customers, the federal deposit insurance fund, 
and the stability of the U.S. financial system, not our creditors or shareholders. Existing state and federal banking laws subject us to 
substantial limitations with respect to our activities, including the making of loans, the purchase of securities, the payment of dividends and 
many other aspects of our business. Some of these laws may benefit us, others may increase our costs of doing business, or otherwise 
adversely affect us and create competitive advantages for others. Regulations affecting banks and financial services companies undergo 
continuous change, which may be accelerated by changes in the administration of federal and state governments, and we cannot predict the 
ultimate effect of these changes, which could have a material adverse effect on our profitability or financial condition. Federal economic and 
monetary policy may also affect our ability to attract deposits, make loans and achieve satisfactory interest spreads. The implementation, 
amendment or repeal of federal financial services laws or regulations may limit our business opportunities, impose additional costs on us, 
impact our revenues or the value of our assets, or otherwise adversely affect our business, financial condition or results of operations.

16

Minimum capital requirements may adversely affect our ability (and that of our bank) to pay cash dividends, reduce our 
profitability, or otherwise adversely affect our business, financial condition or results of operations.

We are subject to extensive capital regulations imposed by federal and state banking regulations. These regulations, among other 
things, establish minimum requirements to qualify as a “well-capitalized” institution. If our bank were to fail to maintain its status of “well-
capitalized” under the applicable regulatory capital regulations, we may lose our status as a financial holding company and be subjected to a 
consent agreement requiring us to bring our bank back to a “well-capitalized” status. Such an agreement may impose restrictions on our 
activities. If we were to fail to enter into such an agreement, or fail to comply with the terms of such agreement, the Federal Reserve may 
impose more severe restrictions on our activities, including requiring us to cease and desist activities permitted under the Bank Holding 
Company Act of 1956. The regulatory environment is constantly evolving, with requirements frequently being introduced or amended. It is 
possible that increases in regulatory capital requirements and changes in how regulatory capital is calculated could require us to increase our 
capital levels by issuing additional securities that qualify as regulatory capital, thus potentially diluting our existing shareholders, or by taking 
other actions, such as selling assets, in order to maintain required capital ratios. We may be unable to sell some of our assets, or we may have 
to sell assets at a discount from market value, either of which could adversely affect our results of operations, cash flow and financial
condition.

Risks Related to Our Stock

Issuance of debt securities or sales of our common stock or other securities may dilute the value of our common stock.

We have issued both trust preferred securities and subordinated notes. In the event of our liquidation, the holders of our debt 
securities would receive a distribution of our available assets before distributions are made to holders of our common stock. In many 
situations, our Board of Directors has the authority, without any vote of our shareholders, to issue shares of our authorized but unissued 
preferred or common stock, including shares authorized and unissued under our equity incentive plans. In the future, we may issue additional 
debt or equity securities, through public or private offerings, in order to raise additional capital. Any such issuance of equity securities would 
dilute the percentage of ownership interest of existing shareholders and may dilute the per share book value of the common stock. In addition, 
option holders under our stock-based incentive plans may exercise their options at a time when we would otherwise be able to obtain 
additional equity capital on more favorable terms.

We may need to raise additional capital in the future, and such capital may not be available when needed or at all.

We may need or want to raise additional capital in the future by issuing debt or equity securities to provide us with sufficient capital 

resources and liquidity to meet our commitments and business needs, particularly if our asset quality or earnings were to deteriorate 
significantly. Our ability to raise additional capital will depend on, among other things, conditions in the capital markets at that time, which 
are outside of our control, and our financial performance. Economic conditions and any loss of confidence in financial institutions generally 
may increase our cost of funding and limit access to certain customary sources of capital.

There can be no assurance that capital will be available on acceptable terms or at all. Any occurrence that may limit our access to 

the capital markets, such as a decrease in our credit rating or a decline in the confidence of equity or debt purchasers, or counterparties 
participating in the capital markets, may adversely affect our capital costs and our ability to raise capital and, potentially, our liquidity. Also, 
if we need to raise capital in the future, we may have to do so when many other financial institutions are also seeking to raise capital and 
would have to compete with those institutions for investors. An inability to raise additional capital on acceptable terms when needed could 
have a materially adverse effect on our business, financial condition and results of operations.

17

Our Articles of Incorporation, By-laws, the corporate laws of the State of Michigan, and federal banking laws contain provisions that 
may discourage or prevent a takeover of our company and reduce any takeover premium.

Our Articles of Incorporation, By-laws, the corporate laws of the State of Michigan, and federal banking laws include provisions 
which are designed to provide our Board of Directors with time to consider whether a hostile takeover offer is in our and our shareholders’ 
best interest. These provisions, however, could discourage potential acquisition proposals and could delay or prevent a change in control. The 
provisions also could diminish the opportunities for a holder of our common stock to participate in tender offers, including tender offers at a 
price above the then-current market price for our common stock. These provisions could also prevent transactions in which our shareholders 
might otherwise receive a premium for their shares over then-current market prices, and may limit the ability of our shareholders to approve 
transactions that they may deem to be in their best interest.

The Michigan Business Corporation Act contains provisions intended to protect shareholders and prohibit or discourage various 
types of hostile takeover activities. In addition to these provisions and the provisions of our Articles of Incorporation and By-laws, federal 
banking laws require the Federal Reserve Board’s approval prior to acquiring “control” of a bank holding company. All of these provisions 
may delay or prevent a change in control without action by our shareholders and could adversely affect the price of our common stock.

There is a limited trading market for our common stock.

The price of our common stock has been, and will likely continue to be, subject to fluctuations based on, among other things,

economic and market conditions for bank holding companies and the stock market in general, as well as changes in investor perceptions of 
our company. The issuance of new shares of our common stock also may affect the market for our common stock.

Our common stock is traded on the Nasdaq Global Select Market under the symbol “MBWM.” The development and maintenance 

of an active public trading market depends upon the existence of willing buyers and sellers, the presence of which is beyond our control.
While we are a publicly traded company, the volume of trading activity in our stock is still relatively limited. Even if a more active market 
develops, there can be no assurance that such a market will continue, or that our shareholders will be able to sell their shares at or above the 
price at which they acquired shares.

The value of securities in our investment securities portfolio may be negatively affected by disruptions in securities markets.

Prices and volumes of transactions in the nation’s securities markets can be affected suddenly by economic crises, or by other

national or international crises, such as national disasters, acts of war or terrorism, changes in commodities markets, or instability in foreign 
governments. Disruptions in securities markets may detrimentally affect the value of securities that we hold in our investment portfolio, such 
as through reduced valuations due to the perception of heightened credit and liquidity risks. There can be no assurance that declines in market 
value associated with these disruptions will not result in a loss in principal value of these assets, which would lead to accounting charges that 
could have a material adverse effect on our net income and capital levels.

Item 1B. Unresolved Staff Comments

We have received no written comments regarding our periodic or current reports from the staff of the Securities and Exchange 

Commission that were issued 180 days or more before the end of our 2024 fiscal year and that remain unresolved.

Item 1C. Cybersecurity

Risk Management and Strategy

Our enterprise risk management program is designed to identify, assess, and mitigate risks across various aspects of our company, including financial, 
operational, regulatory, reputational, and legal. Cybersecurity is a critical component of this program given the increasing reliance on technology and potential of 
cyber threats. Our Chief Information Security Officer (the "CISO") is primarily responsible for this cybersecurity component and is a key member of the risk 
management organization, reporting directly to the Senior Management Team (“SMT”) and our Tech Oversight Committee. Our Tech Oversight Committee 
includes members of our Board and management. Our CISO has served in this capacity for more than a decade and maintains multiple certifications issued by the 
Information Systems Audit and Control Association ("ISACA") and the SANS Institute. As part of our overall enterprise risk management program, we maintain 
both an Information & Cyber Security Program Policy (“ICSPP”) and Information & Cyber Security Incident Response Policy (“ICSIRP”).

Our ICSPP is overseen by the SMT, which is responsible for designating the CISO. The CISO is responsible for leading company-wide cybersecurity 

strategy, policy, standards, architecture, and processes. The CISO is charged with all logical security related matters, which include but are not limited to, 
PC/server security, network security, internet security, and database and application security. Our ICSIRP is based on applicable federal and state laws as well as 
cybersecurity incident response best practices. The purpose of the ICSIRP is to define procedures for reporting and responding to cybersecurity incidents. It 
creates objectives for actionable procedures that can be measured, evaluated, scaled and revised as necessary for each specific incident. These objectives include 
maximizing the effectiveness of our company's operations through an established plan of action and assigning responsibilities to appropriate personnel and/or
third-party contractors.

Our company has engaged a third-party managed detection and response company to monitor the security of our information systems around-the-

clock, including intrusion detection and response, and to provide instantaneous alerting should a cybersecurity event occur. If a cybersecurity threat or 
cybersecurity incident is identified through our company's information systems, the CISO and Incident Response Team (“IRT”) will take immediate steps to 
mitigate the threat and assess any damages. Upon report from the CISO, the SMT will evaluate the materiality of the cybersecurity threat or cybersecurity incident 
to determine if any public disclosures are required under the Security and Exchange Commission’s cybersecurity disclosure rule. If deemed necessary, third-party 
consultants, legal counsel, and assessors will be engaged to evaluate the materiality assessment.

Our company has training and awareness programs designed to educate its employees about cybersecurity risks and how to protect our company, our 
customers and themselves from cyber-attacks and to keep its employees informed about cybersecurity threats and how to stay safe online, including secure access 
practice, phishing schemes, remote work and response to suspicious activities.

Our cybersecurity program interfaces with other functional areas within our company, including but not limited to, our company's business segments 

and information technology, legal, risk, human resources and internal audit departments, as well as external third-party partners, to identify and understand 
potential cybersecurity threats. We regularly assess and update our processes, procedures and management techniques in light of ongoing cybersecurity 
developments.

Recognizing the complexity and evolving nature of cybersecurity threats, we also engage with a range of external experts, including cybersecurity 

assessors, consultants, and auditors in evaluating and testing our risk management systems. These partnerships enable our company to leverage specialized 
knowledge and insights, ensuring its cybersecurity strategies and processes remain at the forefront of industry best practices. Our company's collaboration with 
these third parties includes regular audits, testing, threat assessments and consultation on security enhancements.

To date, risks from cybersecurity threats or incidents have not materially affected our company. However, the sophistication of and risks from 

cybersecurity threats and incidents continue to increase, and the preventative actions that we have taken and continue to take to reduce the risk of cybersecurity 
threats and incidents and protect our systems and information may not successfully protect against all cybersecurity threats and incidents. For more information on 
how cybersecurity risk could materially affect our company's business strategy, results of operations, or financial condition, please refer to Item 1A Risk Factors.

Governance

Our company recognizes the importance of safeguarding company and customer information. Therefore, the Board of Directors recognizes that the 
protection of this information ranks as one of our highest priorities. The Board of Directors is responsible for reviewing and approving the ICSPP and ICSIRP at 
least annually and monitoring material risks facing our company. The Board recently added a member who possesses specialized expertise in cybersecurity 
matters. Director Sara A. Schmidt currently serves as chief information security officer for US Foods and executive sponsor of the West Michigan Cyber Security 
Consortium.

The Board has tasked the SMT with overseeing efforts to develop, implement and maintain an effective information and cybersecurity program. The 
SMT designates the CISO who also serves as the IRT leader. As part of its oversight responsibilities, the Board of Directors is responsible for discussing with the 
SMT our company’s major risk exposures, such as cybersecurity, and the steps management has taken to monitor and control those exposures, including our risk 
assessment and risk management policies. The Board of Directors also monitors our compliance with legal and regulatory requirements and the risks associated 
therewith. On a regular basis, our Tech Oversight Committee reviews with the SMT significant areas of risk exposure involving cybersecurity.

At the direction of the SMT, the CISO and IRT monitor internal and external cybersecurity threats and review and revise our company’s cybersecurity 

defenses on an ongoing basis. The CISO, together with other members of the IRT, bring a wealth of expertise to their respective roles, including expertise in 
security technologies; designing and implementing security strategies; security standards such as NIST, ISO, COBIT and ITIL; and risk management and incident 
response. The CISO prepares reports on IT general controls and cybersecurity metrics for the SMT and Tech Oversight Committee periodically. The Board of 
Directors meets with the CISO periodically to discuss cybersecurity.

Properties.

Our headquarters is located in our bank’s main office facility in Grand Rapids, Michigan. Our bank operates 43 banking offices 
primarily concentrated throughout Western and Central Michigan, most of which are full-service facilities. We also have banking offices 
located in the metropolitan Detroit, Michigan area, Traverse City, Michigan, Petoskey, Michigan, Saginaw, Michigan, and Midland, 
Michigan. We have larger banking facilities in Kalamazoo, Lansing, Mt. Pleasant and West Branch. The remaining banking offices generally 
range in size from 1,200 to 3,200 square feet, based on the location and number of employees located at the facility. All of our banking 
offices are owned by our bank except for ten that are rented under various operating lease agreements. In addition, certain functions operate 
out of our standalone facility located in Alma, Michigan.

We consider our properties and equipment to be well maintained, in good operating condition and capable of accommodating 

current growth forecasts. However, we may choose to add branch locations to expand our presence in current markets and/or in new markets
or, alternatively, to consolidate, close or relocate branches if we believe it would be beneficial to our overall performance.

Item 3.

Legal Proceedings.

From time to time, we may be involved in various legal proceedings that are incidental to our business. In the opinion of 
management, we are not a party to any legal proceedings that are material to our financial condition, either individually or in the aggregate.

Holders of our common stock are entitled to receive dividends that the Board of Directors may declare from time to time. We may 

only pay dividends out of funds that are legally available for that purpose. We are a financial holding company and substantially all of our 
assets are held by our bank. Our ability to pay dividends to our shareholders depends primarily on our bank’s ability to pay dividends to us. 
Dividend payments and extensions of credit to us from our bank are subject to legal and regulatory limitations, generally based on capital 
levels and current and retained earnings, imposed by law and regulatory agencies with authority over our bank. The ability of our bank to pay 
dividends is also subject to its profitability, financial condition, capital expenditures and other cash flow requirements. In addition, under the 
terms of our subordinated debentures, we would be precluded from paying dividends on our common stock if an event of default has 
occurred and is continuing under the subordinated debentures, or if we exercised our right to defer payments of interest on the subordinated 
debentures, until the deferral ended.

We and our bank are subject to regulatory capital requirements administered by state and federal banking agencies. Failure to meet 
the various capital requirements can initiate regulatory action that could have a direct material effect on our financial statements. Our ability 
to pay cash and stock dividends or repurchase equity securities is subject to limitations under various laws and regulations and to prudent and 
sound banking practices.

On January 11, 2024, our Board of Directors declared a cash dividend on our common stock in the amount of $0.35 per share that 

was paid on March 13, 2024 to shareholders of record as of March 1, 2024. On April 11, 2024, our Board of Directors declared a cash 
dividend on our common stock in the amount of $0.35 per share that was paid on June 19, 2024 to shareholders of record as of June 7, 2024. 
On July 11, 2024, our Board of Directors declared a cash dividend on our common stock in the amount of $0.36 per share that was paid on 
September 18, 2024 to shareholders of record as of September 6, 2024. On October 10, 2024, our Board of Directors declared a cash dividend 
on our common stock in the amount of $0.36 per share that was paid on December 18, 2024 to shareholders of record as of December 6, 
2024.

On January 12, 2023, our Board of Directors declared a cash dividend on our common stock in the amount of $0.33 per share that 

was paid on March 15, 2023 to shareholders of record as of March 3, 2023. On April 13, 2023, our Board of Directors declared a cash 
dividend on our common stock in the amount of $0.33 per share that was paid on June 14, 2023 to shareholders of record as of June 2, 2023. 
On July 13, 2023, our Board of Directors declared a cash dividend on our common stock in the amount of $0.34 per share that was paid on 
September 13, 2023 to shareholders of record as of September 1, 2023. On October 12, 2023, our Board of Directors declared a cash dividend 
on our common stock in the amount of $0.34 per share that was paid on December 13, 2023 to shareholders of record as of December 1, 
2023.

On January 16, 2025, our Board of Directors declared a cash dividend on our common stock in the amount of $0.37 per share that 

will be paid on March 19, 2025 to shareholders of record as of March 7, 2025.

Issuer Purchases of Equity Securities

On May 27, 2021, we announced that our Board of Directors had authorized a program to repurchase up to $20.0 million of our 
common stock from time to time in open market transactions at prevailing market prices or by other means in accordance with applicable
regulations. The actual timing, number and value of shares repurchased under the program will be determined by management in its 
discretion and will depend on a number of factors, including the market price of our stock, general market and economic conditions, our 
capital position, financial performance and alternative uses of capital, and applicable legal requirements. The program may be discontinued at 
any time. No shares were repurchased during 2023 or 2024. Historically, stock repurchases have been funded from cash dividends paid to us 
from our bank. Additional repurchases may be made in future periods under the authorized plan or a new plan, which would also likely be 
funded from cash dividends paid to us from our bank. As of December 31, 2024, repurchases aggregating $6.8 million were available to be 
made under the current repurchase program.

Item 9A. Controls and Procedures.

As of December 31, 2024, an evaluation was performed under the supervision of and with the participation of our management, 

including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls 
and procedures. Based on that evaluation, our management, including our Chief Executive Officer and Chief Financial Officer, concluded 
that our disclosure controls and procedures were effective as of December 31, 2024.

There have been no significant changes in our internal control over financial reporting during the year ended December 31, 2024, 

that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is 
defined in Exchange Act Rules 13a-15(f). There are inherent limitations in the effectiveness of any system of internal control. Accordingly, 
even an effective system of internal control can provide only reasonable assurance with respect to financial statement preparation.

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial

Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2024. This 
evaluation was based on criteria for effective internal control over financial reporting described in Internal Control – Integrated Framework 
(2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). Based on our evaluation under the 
COSO framework, our management concluded that our internal control over financial reporting was effective as of December 31, 2024. Refer

FORWARD-LOOKING STATEMENTS

The following discussion and other portions of this Annual Report contain forward-looking statements that are based on management’s 
beliefs, assumptions, current expectations, estimates, and projections about the financial services industry, the economy, and our company. 
Words such as “anticipates,” “believes,” "could," “estimates,” “expects,” “intends,” “plans,” “projects,” “indicates,” “strategy,” “future,” 
“likely,” “may,” “should,” “will,” and variations of such words and similar expressions are intended to identify such forward-looking 
statements. These statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions (“Future 
Factors”) that are difficult to predict with regard to timing, extent, likelihood, and degree of occurrence. Therefore, actual results and 
outcomes may materially differ from what may be expressed or forecasted in such forward-looking statements. We undertake no obligation to 
update, amend, or clarify forward-looking statements, whether as a result of new information, future events (whether anticipated or 
unanticipated), or otherwise.

Future Factors include, among others, adverse changes in interest rates and interest rate relationships; increasing rates of inflation and slower 
growth rates; significant declines in the value of commercial real estate; market volatility; demand for products and services; climate impacts; 
labor markets; the degree of competition by traditional and non-traditional financial services companies; changes in banking regulation or 
actions by bank regulators; changes in tax laws; changes in prices, levies, and assessments; the impact of technological advances; potential 
cyber-attacks, information security breaches, and other criminal activities; litigation liabilities; governmental and regulatory policy changes; 
the outcomes of existing or future contingencies; trends in customer behavior as well as their ability to repay loans; changes in local real 
estate values; damage to our reputation resulting from adverse publicity, regulatory actions, litigation, operational failures, and the failure to 
meet client expectations and other facts; changes in the national and local economies, and unstable political and economic environments; and 
risk factors described in our annual report on Form 10-K for the year ended December 31, 2024. These are representative of the Future 
Factors that could cause a difference between an ultimate actual outcome and a forward-looking statement.

Discussions of 2022 items and year-to-year comparisons between 2023 and 2022 that are not included in this Form 10-K can be found in 
“Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the 
fiscal year ended December 31, 2023.

CRITICAL ACCOUNTING ESTIMATES

Management’s Discussion and Analysis of Financial Condition and Results of Operations (“Management’s Discussion and Analysis”) is 
based on Mercantile Bank Corporation’s consolidated financial statements, which have been prepared in accordance with accounting 
principles generally accepted in the United States of America. The preparation of these financial statements requires us to make estimates and 
judgments that affect the reported amounts of assets, liabilities, revenues and expenses. Our critical accounting estimates are highly 
dependent upon subjective or complex judgments and assumptions, and changes in such may have a significant impact on the financial 
statements, just as actual results may differ. We have reviewed the application of our critical accounting estimates with the Audit Committee 
of our Board of Directors.

F-3

Allowance For Credit Losses (“allowance”): The allowance is maintained at a level we believe is adequate to absorb estimated credit losses 
identified and expected in the loan portfolio. Our evaluation of the adequacy of the allowance is an estimate based on historical credit loss 
experience, the nature and volume of the loan portfolio, information about specific borrower situations and estimated collateral values, 
guidance from bank regulatory agencies, and assessments of the impact of current and anticipated economic conditions on the loan 
portfolio. While historical credit loss experience provides the basis for the estimation of expected credit losses, our qualitative model 
adjusts for risk factors that are not inherently considered in the quantitative modeling process, but are nonetheless relevant in assessing the 
expected credit losses within the loan portfolio. These adjustments may increase or decrease the estimate of expected credit losses based upon 
the assessed level of risk for each qualitative factor. The various risks that may be considered in making qualitative adjustments include, 
among other things, the impact of (i) changes in lending policies and procedures, (ii) changes in the nature and volume of the loan portfolio 
and in the terms of loans, (iii) changes in the experience, ability and depth of lending management and staff, (iv) changes in the volume and 
severity of past due loans, nonaccrual loans and adversely classified loans, (v) changes in the quality of the credit review function, (vi) 
changes in the value of underlying collateral dependent loans, (vii) existence and effect of any concentrations of credit and any changes in
such, and (viii) effect of other factors such as competition and legal and regulatory requirements.

Allocations of the allowance may be made for specific loans, but the entire allowance is available for any loan that, in our judgment, should 
be charged-off. Credit losses are charged against the allowance when we believe the uncollectibility of a loan is likely. The balance of the 
allowance represents our best estimate, but significant downturns in circumstances relating to loan quality or economic conditions could 
result in a requirement for an increased allowance in the future. Likewise, an upturn in loan quality or improved economic conditions may 
result in a decline in the required allowance in the future. In either instance, unanticipated changes could have a significant impact on the 
allowance and operating results. The allowance is increased through a provision charged to operating expense. Uncollectible loans are 
charged-off through the allowance, while recoveries of loans previously charged-off are added to the allowance.

See Note 1 – Significant Accounting Policies in the Notes to our Consolidated Financial Statements in this Form 10-K for additional 
information on our estimation process and methodology related to the allowance. See also Note 3 – Loans and Allowance for Credit Losses 
in the Notes to our Consolidated Financial Statements in this Form 10-K for further information regarding our loan portfolio and allowance.

Mortgage Servicing Rights: Mortgage servicing rights are recognized as assets based on the allocated fair value of retained servicing rights 
on loans sold. Servicing rights are carried at the lower of amortized cost or fair value and are expensed in proportion to, and over the period 
of, estimated net servicing income. We utilize a discounted cash flow model to determine the value of our servicing rights. The valuation 
model utilizes mortgage loan prepayment speeds, the remaining lives of the mortgage loan pools, delinquency rates, our cost to service loans, 
and other factors to determine the cash flow that we will receive from servicing each grouping of loans. These cash flows are then discounted 
based on current interest rate assumptions to arrive at the fair value of the right to service those loans. Impairment is evaluated quarterly 
based on the fair value of the servicing rights, using groupings of the underlying loans classified by interest rates. Any impairment of a 
grouping is reported as a valuation allowance.

F-4

Goodwill: Accounting rules require us to determine the fair value of all the assets and liabilities of an acquired entity, and to record their fair 
value on the date of acquisition. We employ a variety of means in determining fair value, including the use of discounted cash flow analysis, 
market comparisons and projected future revenue streams. For those items for which we conclude that we have the appropriate expertise to 
determine fair value, we may choose to use our own calculation of fair value. In other cases, where the fair value is not readily determined, 
consultation with outside parties is used to determine fair value. Once valuations have been determined, the net difference between the price 
paid for the acquired entity and the fair value of the balance sheet is recorded as goodwill. Goodwill is assessed at least annually for 
impairment, with any such impairment recognized in the period identified. A more frequent assessment is performed if there are material 
changes in the market place or within the organizational structure.

INTRODUCTION

This Management’s Discussion and Analysis should be read in conjunction with the consolidated financial statements contained in this 
Annual Report. This discussion provides information about the consolidated financial condition and results of operations of Mercantile Bank 
Corporation and its consolidated subsidiaries, Mercantile Bank (“our bank”) and Mercantile Community Partners LLC ("MCP"), and 
Mercantile Insurance Center, Inc. (“our insurance company”), a subsidiary of our bank. Unless the text clearly suggests otherwise, references 
to “us,” “we,” “our,” or “the company” include Mercantile Bank Corporation and its wholly-owned subsidiaries referred to above.

CLIMATE CHANGE

The potential impact of climate changes on our operations and the needs of our customers remains uncertain. Scientists have proposed that 
the impacts of climate change could include changes in rainfall patterns, water shortages, changes to the water levels of lakes and other 
bodies of water, changing storm patterns and intensities, and changing temperature levels. These changes could be severe and vary by 
geographic location. Climate change may also affect the occurrence of certain natural events, the incidence and severity of which are 
inherently unpredictable, and may impact our borrowers or the value of our loan collateral.

ENVIRONMENTAL, SOCIAL, AND GOVERNANCE MATTERS

Our Sustainability Committee supports our ongoing commitment to environmental, health and safety, corporate social responsibility, 
corporate governance, sustainability, and other public policy matters relevant to our organization. The Sustainability Committee is a cross-
functional management committee, with oversight from the Governance and Nominating Committee and the Board of Directors, that assists 
us in: (1) setting general strategies relating to ESG matters; (2) developing, implementing, and monitoring initiatives and policies based on 
those strategies; (3) recommending communications with employees, investors, and shareholders with respect to ESG matters; and (4) 
monitoring and assessing developments relating to, and improving our understanding of, ESG matters. The committee met three times during 
2024. Highlights for 2024 included expanding the impact of Mercantile Community Partners LLC to facilitate low-income housing tax 
credits, the completion and posting of the 2024 Corporate Sustainability Report, hiring a fulltime Director of Enterprise Excellence at the end 
of 2024 to oversee all ongoing ESG and sustainability efforts, implementation of a sustainability reporting platform, increased support of 
first-time home buyers mortgage programs, and over 27,500 hours of volunteering in the community completed by employees. Our bank 
maintains a Clawback Policy; an Insider Trading Policy; Code of Ethics; Corporate Governance Guidelines; an Anti-Bribery and Anti-
Corruption Policy; an Anti-Money Laundering, Bank Secrecy Act, Customer Identification and Due Diligence Programs Letter; Vendor and 
Supplier Code of Conduct; Environmental Policy; Human Rights Policy; and Supplier Diversity Program Policy; these policies are reviewed 
and approved by our Board of Directors at least annually and can be found on our website.

FINANCIAL OVERVIEW

We recorded net income of $79.6 million, or $4.93 per basic and diluted share, for 2024, compared with net income of $82.2 million, or 
$5.13 per basic and diluted share, for 2023. While noninterest income increased during 2024, net income was negatively impacted by 
expected lower net interest income and higher noninterest expenses.

Commercial loans increased $292 million, or approximately 9%, during 2024. Multi-family and residential rental property loans were up 
$143 million, nonowner-occupied commercial real estate (“CRE”) loans grew $92.7 million, commercial and industrial loans increased $32.7 
million, and owner-occupied CRE loans were up $31.2 million, while vacant land, land development, and residential construction loans 
decreased $7.8 million. As a percentage of total commercial loans, commercial and industrial loans and owner-occupied CRE loans 
combined equaled 54.9% at December 31, 2024, compared to 57.7% at year-end 2023. The new commercial loan pipeline remains strong, 
and at December 31, 2024, we had $245 million in unfunded loan commitments on commercial construction and development loans that are 
in the construction phase.

Residential mortgage loans decreased $9.8 million, or approximately 1%, during 2024. Residential mortgage loan originations totaled $485 
million during 2024, compared to $386 million in 2023. Approximately 78% of the residential mortgage loans originated during 2024 were 
done so with the intent to sell, compared to about 53% in 2023. The increases in volume of loans originated and percentage of loans sold had 
a positive impact on mortgage banking income.

The overall quality of our loan portfolio remains strong, with nonperforming loans equaling 0.12% of total loans as of December 31, 
2024. Accruing loans past due 30 to 89 days remain low, with little foreclosed property activity throughout 2024. Loan charge-offs totaled 
$3.8 million during 2024, while recoveries of prior period loan charge-offs totaled $0.9 million, providing for net loan charge-offs of $2.9 
million, or 0.06% of average total loans, for the year.

Interest-earning deposits, a vast majority of which is comprised of funds on deposit with the Federal Reserve Bank of Chicago, are used to 
manage daily liquidity needs and interest rate risk sensitivity. The average balance of these funds equaled $237 million during 2024, 
compared to $107 million in 2023. The higher average balance primarily reflects an increase in deposits associated with our strategic 
initiative to lower the loan-to-deposit ratio.

F-6

Total deposits increased $797 million during 2024, providing for a growth rate of approximately 20%. A majority of the growth was in 
money market and time deposit products. Federal Home Loan Bank of Indianapolis (“FHLBI”) advances declined $80.8 million during 
2024. Wholesale funds, comprised of out-of-area deposits and FHLBI advances, totaled $537 million, or about 10% of total funds, as of 
December 31, 2024.

Net interest income decreased $2.5 million during 2024 compared to 2023. Interest income was up $50.1 million, in large part reflecting 
$569 million of growth in average earning assets and a 34 basis point increase in the yield on average earning assets. Interest expense was up 
$52.6 million, primarily reflecting $699 million growth in average interest-bearing liabilities and a 91 basis point increase in the cost of 
interest-bearing liabilities.

We recorded a credit loss provision expense of $7.4 million during 2024, compared to $7.7 million during 2023. The provision expense 
recorded during 2024 was generally necessitated by increased required reserve levels stemming from loan growth, slower residential 
mortgage loan prepayment speeds and specific allocations for two nonperforming nonreal-estate-related commercial loan relationships.

Noninterest income increased $8.2 million during 2024 compared to 2023, primarily reflecting higher mortgage banking income and service 
charges on deposit accounts, the latter stemming from growth in treasury management fees. Growth in payroll service income and revenue 
associated with a private equity investment also benefited noninterest income during 2024, as well as benefit claims on bank owned life 
insurance policies.

Noninterest expense increased $10.5 million during 2024 compared to 2023. Aggregate salary and benefit costs grew $9.1 million, primarily 
reflecting annual merit pay increases, market adjustments, higher bonus/incentive accruals and residential mortgage lender commissions, 
lower residential mortgage loan deferred salary costs and increased medical insurance expenses. Increased data processing costs were also 
recorded during 2024, largely reflecting higher transaction volumes and software support costs, along with the introduction of new treasury 
management products and services.

FINANCIAL CONDITION

Our total assets increased $699 million during 2024, and totaled $6.05 billion as of December 31, 2024. Total loans increased $297 million, 
securities available for sale were up $113 million and interest-earning deposits grew $276 million. Total deposits increased $797 million and 
shareholders’ equity grew $62.4 million, while securities sold under agreements to repurchase (“sweep accounts) decreased $108 million and 
FHLBI advances declined $80.8 million.

F-7

Earning Assets
Average earning assets equaled 94.4% of average total assets during both 2024 and 2023. The loan portfolio continued to comprise a 
majority of earning assets, followed by securities and interest-earning deposits. Average total loans equaled 82.9% of average earning assets 
during 2024, compared to 84.7% in 2023, while average securities and interest-earning deposits comprised 12.7% and 4.4% of average 
earning assets during 2024 and 13.1% and 2.2% of average earning assets during 2023, respectively.

Our loan portfolio has historically been primarily comprised of commercial loans. Commercial loans increased $292 million, or 
approximately 9%, during 2024. Multi-family and residential rental property loans were up $143 million, nonowner-occupied CRE loans 
grew $92.7 million, commercial and industrial loans increased $32.7 million, and owner-occupied CRE loans were up $31.2 million, while 
vacant land, land development, and residential construction loans decreased $7.8 million. As a percentage of total commercial loans, 
commercial and industrial loans and owner-occupied CRE loans combined equaled 54.9% at December 31, 2024, compared to 57.7% at year-
end 2023. We believe our commercial loan portfolio remains well diversified.

As of December 31, 2024, availability on commercial construction and development loans that are in the construction phase totaled $245 
million, 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 $296 million in new lending commitments, a majority of which we expect 
to be accepted and funded over the next 12 to 18 months. Our commercial lenders 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 established within our commercial loan portfolio. Usage of existing 
commercial lines of credit was relatively stable during 2024 at approximately 42%, a small increase from 2023 but similar to our historical 
average.

Residential mortgage loans decreased $9.8 million, or approximately 1%, during 2024. Residential mortgage loan originations totaled $485 
million during 2024, compared to $386 million in 2023. Approximately 78% of the residential mortgage loans originated during 2024 were 
done so with the intent to sell, compared to about 53% in 2023. In mid-2023, we altered our residential mortgage loan pricing strategy to 
encourage borrowers to select fixed rate residential loan products that we could sell rather than selecting adjustable rate residential mortgage 
loan products that we had to fund on our balance sheet. The strategy not only provided for less residential mortgage loans being funded on 
our balance sheet, but also resulted in higher mortgage banking income. The increased volume of loans originated also benefited mortgage 
banking income.

Other consumer-related loans totaled $65.9 million, or 1.4% of total loans, at December 31, 2024. We expect this loan portfolio segment to 
remain relatively steady in dollar amount but decline as a percent of total loans in future periods as the commercial loan segment grows.

The following table presents total loans outstanding as of December 31, 2024, according to scheduled repayments of principal on fixed rate 
loans and repricing frequency on variable rate loans. Floating rate commercial loans that are currently at interest rate floors are treated as

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 items 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 
restructuring in the future, are included on the internal loan 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 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 $5.7 million, or 0.12% of total loans, as of December 31, 2024, compared to $3.4 million, or 0.08% of total 
loans, as of December 31, 2023. Accruing loans past due 30 to 89 days remain low, with little foreclosed property activity throughout 
2024. The volume of nonperforming assets has remained under 0.3% of total assets since year-end 2015, and has averaged 0.1% over the 
past six years. Given the low level of nonperforming loans and accruing loans 30 to 89 days delinquent, combined with what we believe are 
strong credit administration practices, we are pleased with the overall quality of the loan portfolio.

Loan charge-offs totaled $3.8 million during 2024, while recoveries of prior period loan charge-offs totaled $0.9 million, providing for net 
loan charge-offs of $2.9 million, or 0.06% of average total loans, for the year. Loan charge-offs totaled $0.9 million during 2023, while 
recoveries of prior period loan charge-offs totaled $0.8 million, providing for net loan charge-offs of $0.1 million, or less than 0.01% of 
average total loans, for the year. We continue our collection efforts on charged-off loans, and we 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.

The primary risk elements with respect to commercial loans are the financial condition of the borrower, the sufficiency of collateral, and the 
timeliness of scheduled payments. We have a policy of requesting and reviewing periodic financial statements from commercial loan 
customers, and we have a disciplined and formalized review of the existence of collateral and its value. The primary risk element with 
respect to each residential mortgage loan and consumer loan is the timeliness of scheduled payments. We have a reporting system that 
monitors past due loans and have adopted policies to pursue creditors’ rights in order to preserve our collateral position.

See Note 1 - Significant Accounting Policies in this Form 10-K for further detailed descriptions of our estimation process and methodology 
related to the allowance. See also Note 3 - Loans and Allowance for Credit Losses in this Form 10-K for further information regarding our 
loan portfolio and allowance.

The allowance equaled $54.5 million, or 1.18% of total loans, and over 900% of nonperforming loans, as of December 31, 2024. The 
allowance was comprised of $52.3 million in general reserves relating to performing loans and $2.2 million in specific reserves on other 
loans, primarily nonperforming loans, at year-end 2024. Loans with an aggregate carrying value of $1.1 million as of December 31, 2024 
had been subject to previous partial charge-offs aggregating $4.0 million over the past several years, including $3.8 million during 2024. As 
of December 31, 2024, there were no specific reserves allocated to loans that had been subject to a previous partial charge-off.

Although we believe the allowance is adequate to absorb loan losses in our originated loan portfolio as they arise, there can be no assurance 
that we will not sustain loan losses in any given period that could be substantial in relation to, or greater than, the size of the allowance.

Securities available for sale increased $113 million during 2024, totaling $730 million as of December 31, 2024. Purchases of U.S. 
Government agency bonds during 2024 aggregated $143 million, while proceeds from matured U.S. Government agency bonds totaled $44.0 
million. There were no purchases of U.S. Government agency guaranteed mortgage-backed securities during 2024; principal paydowns on 
U.S. Government agency guaranteed mortgage-backed securities totaled $3.4 million. Purchases of municipal bonds totaled $31.1 million 
during 2024; proceeds from matured municipal bonds totaled $14.4 million. At December 31, 2024, the portfolio was primarily comprised of 
U.S. Government agency bonds (68%), municipal bonds (29%), and U.S. Government agency guaranteed mortgage-backed securities 
(3%). All of our securities are currently designated as available for sale and are therefore stated at fair value. The fair value of securities 
designated as available for sale at December 31, 2024 totaled $730 million, including a net unrealized loss of $63.1 million. The net 
unrealized loss equaled $63.9 million as of December 31, 2023. 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 upcoming 
purchases to generally consist of U.S. Government agency and municipal bonds, with the securities portfolio maintained at about 12% to 15% 
of total assets.

Market values on our U.S. Government agency bonds, mortgage-backed securities issued or guaranteed by U.S. Government agencies, and 
municipal bonds are generally determined on a monthly basis with the assistance of a third-party vendor. Evaluated pricing models that vary 
by type of security and incorporate available market data are utilized. Standard inputs include issuer and type of security, benchmark yields, 
reported trades, broker/dealer quotes, and issuer spreads. The market value of certain non-rated securities issued by relatively small 
municipalities generally located within our markets is estimated at carrying value. We believe our valuation methodology provides for a 
reasonable estimation of market value, and that it is consistent with the requirements of accounting guidelines.

FHLBI stock totaled $21.5 million as of December 31, 2024, unchanged from December 31, 2023. Our investment in FHLBI stock is 
necessary to engage in their advance and other financing programs. We have regularly received quarterly cash dividends, and we expect a 
cash dividend will continue to be paid in future quarterly periods.

Interest-earning deposits, a vast majority of which is comprised of funds on deposit with the Federal Reserve Bank of Chicago, are used to 
manage daily liquidity needs and interest rate risk sensitivity. The average balance of these funds equaled $237 million during 2024, 
compared to $107 million in 2023. The higher average balance primarily reflects an increase in deposits associated with our strategic
initiative to lower the loan-to-deposit ratio.

Non-Earning Assets
Cash and due from bank balances averaged 1.1% of total assets during 2024, similar to the average level during 2023, with no significant 
changes expected in future periods. Net premises and equipment equaled $53.4 million at December 31, 2024, representing an increase of 
$2.5 million during 2024. Aggregate investments in new and existing offices totaled $8.5 million, while depreciation expense aggregated 
$6.0 million. We had no other real estate owned as of December 31, 2024.

Other assets equaled $148 million at December 31, 2024, reflecting an increase of $22.8 million from year-end 2023. The growth is 
primarily associated with an aggregate $13.6 million increase in low-income housing and historical tax credit investments and a $7.0 million 
purchase of additional bank owned life insurance.

Source of Funds
Total deposits increased $797 million, or over 20%, during 2024, and totaled $4.70 billion at December 31, 2024. Local deposits increased 
$816 million, while out-of-area deposits declined $18.7 million, during 2024. Sweep accounts decreased $108 million, and FHLBI advances 
declined $80.8 million. Wholesale funds, comprised of out-of-area deposits and FHLBI advances, totaled $537 million, or about 10% of total 
funds, as of December 31, 2024.

Money market, local time deposit and interest-bearing checking accounts increased $559 million, $178 million and $103 million, 
respectively, during 2024, largely reflecting growth in deposits from existing customers and initial deposits from new customers stemming 
from our strategic initiative to grow local deposits to lower the loan-to-deposit ratio. Savings deposits declined $40.7 million, primarily 
reflecting transfers to higher-paying money market and time deposit products. Noninterest-bearing checking accounts grew $16.9 million; 
however, that includes a business deposit of approximately $90 million made near the end of 2024 that was withdrawn in early 2025. On an 
average basis, noninterest-bearing checking accounts declined $199 million during 2024 compared to 2023, largely reflecting transfers to 
higher-paying deposit accounts.

Uninsured deposits totaled approximately $2.5 billion, or about 54% of total deposits, as of December 31, 2024, compared to approximately 
$1.9 billion, or about 48% of total deposits, as of December 31, 2023. The uninsured amounts are estimates based on the methodologies and 
assumptions we use for regulatory reporting requirements. Our level of uninsured deposits, which has remained relatively stable as a 
percentage of total deposits, is generally higher than industry averages given our focus on commercial lending.

The balance of certificates of deposit exceeding the FDIC insured limit and their maturity profile as of December 31, 2024 are as follows:

Sweep accounts declined $108 million during 2024, totaling $122 million as of December 31, 2024. The aggregate balance of this funding 
type can be subject to relatively large daily fluctuations given the nature of the customers utilizing this product and the sizable balances that 
several of the customers maintain. In addition, we had one customer withdraw a large amount of funds near the end of 2024 that were 
returned in early 2025. The average balance of sweep accounts equaled $225 million during 2024 with a high balance of $278 million and a 
low balance of $118 million. Our sweep account program entails transferring collected funds from certain business noninterest-bearing 
checking accounts to overnight interest-bearing repurchase agreements. Such repurchase agreements are not deposit accounts and are not 
afforded federal deposit insurance. All of our sweep accounts are accounted for as secured borrowings.

F-13

FHLBI advances declined $80.8 million during 2024, totaling $387 million as of December 31, 2024. Bullet advances aggregating $10.0 
million were obtained during 2024, while bullet advance maturities aggregated $90.0 million. Payments on amortizing advances totaled $0.8 
million during 2024. Bullet advances are generally obtained to provide funds for loan growth and are used to assist in managing interest rate 
risk, while amortizing advances are generally acquired to match-fund specific longer-term fixed rate commercial loans, with the dollar 
amount and amortization structure of the underlying advances reflective of the associated commercial loans. Advances are collateralized by 
residential mortgage loans, first mortgage liens on multi-family residential property loans, first mortgage liens on certain commercial real 
estate property loans, and substantially all other assets of our bank under a blanket lien arrangement. Our borrowing line of credit at year-end 
2024 totaled $1.0 billion, with remaining availability based on collateral of $634 million.

Shareholders’ equity increased $62.4 million during 2024, totaling $585 million as of December 31, 2024. Positively impacting 
shareholders’ equity was net income of $79.6 million, while negatively affecting shareholders’ equity were cash dividends on our common 
stock totaling $22.5 million. Activity relating to the issuance and sale of common stock through various stock-based compensation programs 
and our dividend reinvestment plan positively impacted shareholders’ equity by a total of $4.6 million. Positively impacting shareholders’ 
equity during 2024 was a $0.7 million decline in the after-tax net unrealized loss on available for sale securities.

RESULTS OF OPERATIONS
FOR THE YEARS ENDED DECEMBER 31, 2024 AND 2023

Summary
We recorded net income of $79.6 million, or $4.93 per basic and diluted share, for 2024, compared to net income of $82.2 million, or $5.13 
per basic and diluted share, for 2023. Diluted earnings per share decreased $0.20, or 3.9%, during 2024 compared to 2023.

The decrease in net income during 2024 compared to 2023 reflected increased noninterest expense and lower net interest income, which more 
than offset higher noninterest income and a reduced provision for credit losses. Noninterest expense was up in 2024 primarily due to 
increased salary and benefit and data processing costs. Net interest income declined during 2024 as growth in earning assets, most notably in 
loans, and a higher yield on earning assets were more than offset by growth in interest-bearing liabilities and an increased cost of funds. The 
provision expense recorded during 2024 and 2023 included allocations necessitated by net loan growth, slower residential mortgage loan 
prepayment rates and the associated extended average life of the portfolio, and changes in environmental factors. Individual allocations 
created for two deteriorated commercial loan relationships also contributed to the provision expense recorded during 2024. Noninterest 
income increased significantly during 2024, largely reflecting growth in mortgage banking income, treasury management fees, bank owned 
life insurance income, and payroll services fees, along with revenue associated with an investment in a private equity fund.

Net Interest Income
Net interest income, the difference between revenue generated from earning assets and the interest cost of funding those assets, is our primary 
source of earnings. Interest income (adjusted for tax-exempt income) and interest expense totaled $321 million and $130 million, respectively, 
during 2024, providing for net interest income of $191 million. During 2023, interest income and interest expense equaled $272 million and 
$77.8 million, respectively, providing for net interest income of $194 million. In comparing 2024 with 2023, interest income increased 18.5%, 
interest expense was up 67.6%, and net interest income decreased 1.3%. The level of net interest income is primarily a function of asset size, 
as the weighted average interest rate received on earning assets is greater than the weighted average interest cost of funding sources; however, 
factors such as types and levels of assets and liabilities, the interest rate environment, interest rate risk, asset quality, liquidity, and customer 
behavior also impact net interest income as well as the net interest margin. The $2.5 million decline in net interest income in 2024 compared 
to 2023 resulted from a decreased net interest margin, which more than offset an increase in earning assets, particularly in loans.

During 2024, the net interest margin equaled 3.58%, down from 4.05% during 2023 due to a higher cost of funds, which more than offset an 
increase in the yield on average earning assets. The cost of funds rose from 1.63% in 2023 to 2.44% in 2024 mainly due to higher costs of 
deposits and borrowed funds, largely reflecting the impact of a rising interest rate environment. A change in funding mix, primarily 
consisting of a decrease in average noninterest-bearing and lower-cost deposits and an increase in average higher-cost money market 
accounts and time deposits, also contributed to the higher cost of funds. The increases in money market accounts and time deposits stemmed 
from new deposit relationships, growth in existing deposit relationships, and deposit migration. The yield on average earning assets was 
6.02% during 2024, an increase from 5.68% during the prior year. The higher yield primarily resulted from an increased yield on loans. The 
yield on loans was 6.61% during 2024, up from 6.25% during 2023 mainly due to higher interest rates on variable-rate commercial loans 
stemming from the Federal Reserve’s Federal Open Market Committee (“FOMC”) raising the targeted federal funds rate in an effort to 
reduce elevated inflation levels and a significant level of commercial loans being originated over the past 24 months in the higher interest rate 
environment. The FOMC increased the targeted federal funds rate by 100 basis points during the period of February 2023 through July 2023, 
during which time average variable-rate commercial loans represented approximately 65% of average total commercial loans. The positive 
impact of the rate hikes was partially mitigated by the FOMC’s lowering of the targeted federal funds rate by 100 basis points during the last 
four months of 2024. An improved yield on securities, reflecting the increased interest rate environment, also contributed to the enhanced 
yield on average earning assets. During 2024, earning assets averaged $5.35 billion, up $569 million, or 11.9%, from $4.78 billion during 
2023. Average loans increased $386 million, average interest-earning deposits were up $131 million, and average securities grew $52.6 
million.

The following table depicts the average balance, interest earned and paid, and weighted average rate of our assets, liabilities, and 
shareholders’ equity during 2024, 2023, and 2022. The subsequent table portrays the dollar amount of change in interest income and interest 
expense of interest-earning assets and interest-bearing liabilities, respectively, segregated between change due to volume and change due to 
rate. Tax-exempt securities interest income and yield for 2024, 2023, and 2022 have been computed on a tax equivalent basis using a 
marginal tax rate of 21.0%. Securities interest income was increased by $0.2 million in 2024, 2023, and 2022 for this non-GAAP, but 
industry standard, adjustment. These adjustments equated to increases in our net interest margin of less than one basis point during all three 
years.

Interest income, which is primarily generated from the loan portfolio, increased $50.1 million during 2024 from that earned in 2023, totaling 
$321 million in 2024 compared to $272 million in 2023. The increase in interest income is attributable to growth in, and a higher yield on, 
average earning assets. During 2024 and 2023, earning assets had an average yield (tax equivalent-adjusted basis) of 6.02% and 5.68%, 
respectively. The improved yield on average earning assets primarily resulted from an increased yield on loans, mainly reflecting higher 
interest rates on variable-rate commercial loans stemming from the previously mentioned FOMC rate hikes. An enhanced yield on 
securities, reflecting the increased interest rate environment, also contributed to the improved yield on average earning assets.

Interest income generated from the loan portfolio increased $40.1 million in 2024 compared to the level earned in 2023. Growth in the loan 
portfolio during 2024 resulted in a $25.0 million increase in interest income, while an upturn in loan yield from 6.25% in 2023 to 6.61% in 
2024 resulted in a $15.1 million increase in interest income. The higher yield on loans primarily resulted from an improved yield on 
commercial loans, which increased from 6.84% during 2023 to 7.13% during 2024 mainly due to the aforementioned FOMC rate increases 
and a significant level of commercial loans being originated in the past 24 months in the higher interest rate environment. An improved yield 
on residential mortgage loans, reflecting the increasing interest rate environment, also contributed to the higher yield on loans.

F-16

Interest income generated from the securities portfolio increased $3.3 million in 2024 compared to the level earned in 2023. A rise in the 
yield on securities from 2.06% during 2023 to 2.40% during 2024 resulted in a $2.2 million increase in interest income, while growth in the 
average balance of the securities portfolio during 2024 resulted in an increase in interest income of $1.1 million. Reflecting a higher average 
balance, interest income on interest-earning deposits increased $6.8 million in 2024 from the level earned in 2023. The growth in average 
securities and interest-earning deposits during 2024 compared to 2023 primarily reflected the success of our strategic initiatives to grow local 
deposits and decrease our loan-to-deposit ratio.

Interest expense is generated from interest-bearing deposits and borrowed funds. Interest expense increased $52.6 million during 2024 from 
that expensed in 2023, totaling $130 million in 2024 compared to $77.8 million in 2023. Growth in the average balance of interest-bearing 
liabilities during 2024 compared to 2023 resulted in a $27.9 million increase in interest expense, while a rise in the cost of these liabilities 
from 2.47% during 2023 to 3.38% during 2024 resulted in an increase in interest expense of $24.7 million. During 2024, interest-bearing 
liabilities averaged $3.85 billion, representing an increase of $699 million, or 22.1%, from the $3.16 billion average during 2023; average 
interest-bearing deposits and borrowings were up $674 million and $24.7 million, respectively. The higher average cost of interest-bearing 
liabilities mainly resulted from increased costs of deposit accounts. An increased cost of borrowings, along with a change in interest-bearing 
liability mix, also contributed to the higher average cost of interest-bearing liabilities. The cost of interest-bearing non-time deposit accounts 
increased from 1.94% during 2023 to 2.76% during 2024, primarily reflecting a change in mix, consisting of an increase in higher-paying 
money market accounts, and higher interest rates paid on business money market and checking accounts, reflecting the increased interest rate 
environment. The cost of time deposits rose from 3.55% during 2023 to 4.72% during 2024 mainly due to higher rates paid on local time 
deposits, reflecting the increased interest rate environment. The cost of borrowed funds increased from 2.90% during 2023 to 3.65% during 
2024, primarily reflecting higher costs of sweep accounts and FHLBI advances stemming from the increased interest rate 
environment. Average higher-cost money market accounts and time deposits represented an increased percentage of average interest-bearing 
liabilities during 2024 compared to 2023, with the growth in these deposits reflecting new deposit relationships, increases in existing deposit 
relationships, and deposit migration.

Growth in the average balance of interest-bearing non-time deposits during 2024 compared to 2023 resulted in a $14.6 million increase in 
interest expense, while a higher average rate paid on these deposits during 2024 equated to a $10.6 million increase in interest expense. An 
increase in the average balance of time deposits during 2024 compared to 2023 resulted in a $12.8 million increase in interest expense, while 
a higher average rate paid on these deposits during 2024 resulted in an $8.0 million increase in interest expense. A higher average rate paid 
on short-term borrowings during 2024 resulted in a $4.6 million increase in interest expense, while growth in the average balance of these 
borrowings equated to a $0.3 million increase in interest expense. An increased average rate paid on FHLBI advances during 2024 resulted 
in a $1.5 million increase in interest expense, while growth in the average balance of advances resulted in a $0.2 million increase in interest 
expense. The $0.1 million increase in interest expense on other borrowings resulted almost evenly from growth in, and a higher average rate 
paid on, these borrowings.

Provision for Credit Losses
Provisions for credit losses of $7.4 million and $7.7 million were recorded during 2024 and 2023, respectively. The provision expense 
recorded during 2024 mainly reflected allocations necessitated by net loan growth, individual allocations made for two deteriorated 
commercial loan relationships, changes in qualitative factors, and an increased allocation stemming from slower prepayments speeds on 
residential mortgage loans, which were partially offset by lower loan loss rates. The provision expense recorded during 2023 primarily 
reflected allocations necessitated by net loan growth, slower residential mortgage loan prepayment rates and the associated extended average 
life of the portfolio, and changes in environmental factors reflecting heightened inherent risk in the commercial construction loan portfolio. 
Sustained strength in loan quality metrics, including low levels of loan charge-offs, during 2024 and 2023 significantly mitigated the amount 
of additional reserves imposed by the previously mentioned factors. Economic forecasts were relatively stable during 2024 and 2023.

Noninterest Income
Noninterest income totaled $40.4 million during 2024, compared to $32.1 million during 2023. Noninterest income during 2024 included 
bank owned life insurance death benefit claims and gains on the sales of other real estate owned totaling $0.7 million and $0.4, respectively, 
while noninterest income during 2023 included gains on the sales of other real estate owned totaling $0.4 million. Excluding these 
transactions, noninterest income increased $7.5 million, or 23.8%, in 2024 compared to 2023. The growth mainly reflected increases in 
mortgage banking income, treasury management fees, and payroll service fees, along with revenue generated from an investment in a private 
equity fund. The higher level of mortgage banking income primarily resulted from increases in the percentage of loans originated with the 
intent to sell, which equaled approximately 78% in 2024 compared to approximately 53% in 2023, and total loan originations, which were up 
approximately 25% in 2024 compared to 2023. The increase in treasury management fees in large part reflected customers’ expanded use of 
cash management products and services. The growth in noninterest income related to these factors was partially offset by a decline in interest 
rate swap income mainly stemming from reduced borrower demand in light of shifting future interest rate expectations. Credit and debit card 
income declined marginally in 2024 compared to 2023; when adjusting for the receipt of a one-time payment from our vendor in association 
with a contract renewal in 2023, credit and debit card income was up slightly in 2024.

F-17

Noninterest Expense
Noninterest expense during 2024 was $126 million, compared to $115 million during 2023. Overhead costs during 2024 included 
contributions to The Mercantile Bank Foundation (the “Foundation”) totaling $1.7 million, while overhead costs during 2023 included 
contributions to the Foundation, a write-down of a former branch facility, and one-time employee benefit and facility-related costs totaling 
$1.8 million. Excluding these transactions, the increase in noninterest expense during 2024 primarily resulted from larger salary and benefit
costs, reflecting annual merit pay increases, market adjustments, higher residential mortgage lender commissions and incentives, lower 
residential mortgage loan deferred salary costs, an increased bonus accrual and associated payroll taxes, higher health insurance claims, and 
increased 401(k) matching contributions. The increase in residential mortgage lender commissions and incentives mainly stemmed from a 
higher level of loan production. Increased data processing costs, primarily reflecting higher transaction volume and software support costs, 
also contributed to the rise in noninterest expense during 2024. A reduced credit reserve for unfunded loan commitments, along with lower 
levels of interest rate swap credit reserves and collateral holding costs, core deposit intangible asset amortization expense, and occupancy 
costs, during 2024 partially mitigated the increases in overhead costs noted above. The decrease in occupancy costs mainly reflected lower 
building rent stemming from branch-related efficiency initiatives.

Federal Income Tax Expense
During 2024, we recorded income before federal income tax of $98.3 million and a federal income tax expense of $18.7 million, compared to 
income before federal income tax of $103 million and a federal income tax expense of $20.5 million during 2023. The $1.8 million decrease 
in federal income tax expense in 2024 compared to 2023 primarily resulted from the lower level of income before federal income tax. We 
recorded net benefits from investments in tax credit structures of $0.2 million and $0.1 million during 2024 and 2023, respectively. The 
aforementioned bank owned life insurance death benefit claims, substantially all of which were nontaxable, positively impacted the effective 
tax rate in 2024.

CAPITAL RESOURCES

Shareholders’ equity increased $62.4 million during 2024, totaling $585 million as of December 31, 2024. Positively impacting 
shareholders’ equity was net income of $79.6 million, while negatively affecting shareholders’ equity were cash dividends on our common 
stock totaling $22.5 million. Activity relating to the issuance and sale of common stock through various stock-based compensation programs 
and our dividend reinvestment plan positively impacted shareholders’ equity by a total of $4.6 million. Positively impacting shareholders’ 
equity during 2024 was a $0.7 million decline in the after-tax net unrealized loss on available for sale securities.

We and our bank are subject to regulatory capital requirements administered by state and federal banking agencies. Failure to meet the 
various capital requirements can initiate regulatory action that could have a direct material effect on the financial statements. As of December 
31, 2024, our bank’s total risk-based capital ratio was 13.9%, compared to 13.4% at December 31, 2023. Our bank’s total regulatory capital 
increased $64.7 million during 2024, primarily reflecting the net impact of net income totaling $89.6 million and cash dividends paid to us 
aggregating $29.1 million. Our bank’s total risk-based capital ratio was also impacted by a $272 million increase in total risk-weighted 
assets, in large part reflecting growth within the commercial lending function. As of December 31, 2024, our bank’s total regulatory capital 
equaled $759 million, or approximately $214 million in excess of the amount necessary to attain the 10.0% minimum total risk-based capital 
ratio, which is among the requirements to be categorized as “well capitalized.”

We maintain a stock repurchase program, which is discussed in Part II, Item 5 “Market for Registrant’s Common Equity, Related Stockholder 
Matters and Issuer Purchases of Equity Securities” in this Annual Report.

LIQUIDITY

Liquidity is measured by our ability to raise funds through deposits, borrowed funds, capital or cash flow from the repayment of loans and 
securities. These funds are used to fund loans, meet deposit withdrawals, and operate our company. Liquidity is essential to our 
business. An inability to maintain sufficient funds through deposits, borrowings, the sales of assets, and other sources could have a material 
adverse effect on our liquidity. Our access to funding sources in amounts adequate to finance our activities could be impaired by factors that 
affect us specifically or the financial services industry in general. Liquidity is primarily achieved through local and out-of-area deposits and 
liquid assets such as securities available for sale, matured and called securities, federal funds sold, and interest-earning deposit 
balances. Asset and liability management is the process of managing the balance sheet to achieve a mix of earning assets and liabilities that 
maximizes profitability, while providing adequate liquidity.

To assist in providing needed funds, we have regularly obtained monies from wholesale funding sources. Wholesale funds, comprised of 
deposits from customers outside of our market areas and advances from the FHLBI, totaled $537 million, or 10.3% of combined deposits and 
borrowed funds as of December 31, 2024, compared to $636 million, or 13.8% of combined deposits and borrowed funds, as of December 
31, 2023.

Sweep accounts declined $108 million during 2024, totaling $122 million as of December 31, 2024. The aggregate balance of this funding 
type can be subject to relatively large daily fluctuations given the nature of the customers utilizing this product and the sizable balances that 
several of the customers maintain. In addition, we had one customer withdraw a large amount of funds near the end of 2024 that were 
returned in early 2025. The average balance of sweep accounts equaled $225 million during 2024, with a high balance of $278 million and a 
low balance of $118 million. Our sweep account program entails transferring collected funds from certain business noninterest-bearing 
checking accounts to overnight interest-bearing repurchase agreements. Such repurchase agreements are not deposit accounts and are not 
afforded federal deposit insurance. All of our sweep accounts are accounted for as secured borrowings.

Information regarding our repurchase agreements as of December 31, 2024 and during 2024 is as follows:

FHLBI advances declined $80.8 million during 2024, totaling $387 million as of December 31, 2024. Bullet advances aggregating $10.0 
million were obtained during 2024, while bullet advance maturities aggregated $90.0 million. Payments on amortizing advances totaled $0.8 
million during 2024. Bullet advances are generally obtained to provide funds for loan growth and are used to assist in managing interest rate 
risk, while amortizing advances are generally acquired to match-fund specific longer-term fixed rate commercial loans, with the dollar 
amount and amortization structure of the underlying advances reflective of the associated commercial loans. Advances are collateralized by 
residential mortgage loans, first mortgage liens on multi-family residential property loans, first mortgage liens on certain commercial real 
estate property loans, and substantially all other assets of our bank under a blanket lien arrangement. Our borrowing line of credit at year-end 
2024 totaled $1.0 billion, with remaining availability based on collateral of $634 million.

We also have the ability to borrow up to $70.0 million on a daily basis through correspondent banks using established unsecured federal 
funds purchased lines of credit; the average balance of these funds was less than $0.1 million during 2024. In contrast, our interest-earning 
deposit account at the Federal Reserve Bank of Chicago averaged $221 million during 2024. We have a line of credit through the Discount 
Window of the Federal Reserve Bank of Chicago. Based on pledged municipal bonds, we could have borrowed up to $153 million at 
December 31, 2024. We have not utilized this line of credit in over 15 years, and we do not plan to access this line of credit in future periods.

In addition to normal loan funding and deposit flow, we must maintain liquidity to meet the demands of certain unfunded loan commitments 
and standby letters of credit. At December 31, 2024, we had a total of $2.07 billion in unfunded loan commitments and $26.5 million in 
unfunded standby letters of credit. Of the total unfunded loan commitments, $1.78 billion were commitments available as lines of credit to 
be drawn at any time as customers’ cash needs vary, and $296 million were for loan commitments generally expected to be accepted and 
become funded within the next 12 to 18 months. We regularly monitor fluctuations in loan balances and commitment levels, and include 
such data in our liquidity management.

We monitor our liquidity position and funding strategies on an ongoing basis, but recognize that unexpected events, economic or market 
conditions, reductions in earnings performance, declining capital levels, or situations beyond our control could cause liquidity 
challenges. While we believe it is unlikely that a funding crisis of any significant degree is likely to materialize, we have developed a 
comprehensive contingency funding plan that provides a framework for meeting liquidity disruptions.

MARKET RISK ANALYSIS

Our primary market risk exposure is interest rate risk and, to a lesser extent, liquidity risk and inflation risk. All of our transactions are 
denominated in U.S. dollars with no specific foreign exchange exposure. We have only limited agricultural-related loan assets and therefore 
have no significant exposure to changes in commodity prices. Any impact that changes in foreign exchange rates and commodity prices 
would have on interest rates is assumed to be insignificant. Interest rate risk is the exposure of our financial condition to adverse movements 
in interest rates.

Inflation risk is the risk that the values of assets or income from investments will be worth less in the future as inflation decreases the value of 
money. During 2022 and 2023, there was a pronounced rise in inflation. As a result, the FOMC significantly increased interest rates in an 
effort to combat inflation. As inflation increased, the value of our investment securities, particularly those with fixed rates and longer 
maturities, declined. In addition, inflation increased salary and benefit costs, as well as the costs of goods and services we use in our business 
operations, such as electricity and other utilities, which increased our noninterest expenses. Furthermore, our customers were also affected 
by inflation and the rising costs of goods and services used in their households and businesses.

Inflationary pressures started to ease during 2024, prompting the FOMC to lower interest rates by an aggregate 100 basis points during the 
last four months of the year. The lower interest rate environment positively impacted the value of our investment securities. However, 
inflation levels remain above the FOMC’s stated goal and interest rates remain higher than they were prior to 2022. Higher than traditional 
cost increases continue throughout the economy, but at lower levels than experienced in 2022 and 2023.

We derive our income primarily from the excess of interest collected on interest-earning assets over the interest paid on interest-bearing 
liabilities. The rates of interest we earn on our assets and owe on our liabilities generally are established contractually for a period of 
time. Since market interest rates change over time, we are exposed to lower profitability if we cannot adapt to interest rate 
changes. Accepting interest rate risk can be an important source of profitability and shareholder value; however, excessive levels of interest 
rate risk could pose a significant threat to our earnings and capital base. Accordingly, effective risk management that maintains interest rate 
risk at prudent levels is essential to our safety and soundness.

F-20

Evaluating the exposure to changes in interest rates includes assessing both the adequacy of the process used to control interest rate risk and 
the quantitative level of exposure. Our interest rate risk management process seeks to ensure that appropriate policies, procedures, 
management information systems, and internal controls are in place to maintain interest rate risk at prudent levels with consistency and 
continuity. In evaluating the quantitative level of interest rate risk, we assess the existing and potential future effects of changes in interest 
rates on our financial condition, including capital adequacy, earnings, liquidity, and asset quality.

We use two interest rate risk measurement techniques. The first, which is commonly referred to as GAP analysis, measures the difference 
between the dollar amounts of interest-sensitive assets and liabilities that will be refinanced or repriced during a given time period. A
significant repricing gap could result in a negative impact to the net interest margin during periods of changing market interest rates.

(1) Floating rate loans that are currently at interest rate floors are treated as fixed rate loans and are reflected using maturity date and not

repricing frequency.

(2) Mortgage-backed securities are categorized by expected maturities based upon prepayment trends as of December 31, 2024.

F-21

The second interest rate risk measurement used is commonly referred to as net interest income simulation analysis. We believe that this 
methodology provides a more accurate measurement of interest rate risk than the GAP analysis, and therefore, it serves as our primary 
interest rate risk measurement technique. The simulation model assesses the direction and magnitude of variations in net interest income 
resulting from potential changes in market interest rates.

Key assumptions in the model include prepayment speeds on various loan and investment assets; cash flows and maturities of interest-
sensitive assets and liabilities; and changes in market conditions impacting loan and deposit volume and pricing. These assumptions are 
inherently uncertain and subject to fluctuation and revision in a dynamic environment; therefore, the model cannot precisely estimate net 
interest income or exactly predict the impact of higher or lower interest rates on net interest income. Actual results will differ from simulated 
results due to timing, magnitude, and frequency of interest rate changes and changes in market conditions and our strategies, among other 
factors.

We conducted multiple simulations as of December 31, 2024, in which it was assumed that changes in market interest rates occurred ranging 
from up 300 basis points to down 400 basis points in equal quarterly instalments over the next twelve months. The following table reflects the 
suggested dollar and percentage changes in net interest income over the next twelve months in comparison to the $222 million in net interest 
income projected using our balance sheet amounts and anticipated replacement rates as of December 31, 2024. The resulting estimates are 
generally within our policy parameters established to manage and monitor interest rate risk.

In addition to changes in interest rates, the level of future net interest income is also dependent on a number of other variables, including: the 
growth, composition, and absolute levels of loans, deposits, and interest-earning deposits and interest-bearing liabilities; level of 
nonperforming assets; economic and competitive conditions; potential changes in lending, investing, and deposit gathering strategies; client 
preferences; and other factors.

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Mercantile Bank Corporation (the “Company”) as of December 31, 2024 
and December 31, 2023, the related statements of income, comprehensive income, stockholders' equity, and cash flows for each of the years 
in the two-year period ended December 31, 2024, and the related notes (collectively referred to as the “ consolidated financial statements”). 
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the 
Company as of December 31, 2024 and December 31, 2023, and the results of its operations and its cash flows for each of the years in the 
two-year period ended December 31, 2024, in conformity with accounting principles generally accepted in the United States of America.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the 
Company’s internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control – Integrated 
Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) and our report 
dated March 3, 2025 expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for the consolidated financial statements. Our responsibility is to express an opinion on the 
Company’s consolidated financial statements based on our audit. We are a public accounting firm registered with the PCAOB and are 
required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and 
regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to 
obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or 
fraud.

Our audit included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due 
to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence 
regarding the amounts and disclosures in the consolidated financial statements. Our audit also included evaluating the accounting principles 
used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. 
We believe that our audit provides a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that 
was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to 
the consolidated financial statements, and (2) involved our especially challenging, subjective, or complex judgments. The communication of 
critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by 
communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to 
which it relates.

Allowance for Credit Losses – General Reserve

As described in Notes 1 and 3 to the consolidated financial statements, management’s estimate of the allowance for credit losses (ACL) at 
December 31, 2024, includes a reserve on collectively evaluated loans. The reserve on collectively evaluated loans is based on the bank’s 
historical loss rate adjusted for changes in macroeconomic conditions and qualitative factors. The reserve is based on an institution-specific 
historical average loss rate applied over the remaining life of loans. During each reporting period, management considers the need to adjust 
the historical loss rates to reflect the extent to which they expect current conditions and reasonable and supportable economic forecasts to 
differ from the conditions that existed for the period over which the historical loss information was determined. Management’s adjustment for 
qualitative factors is based on the impact of changes in lending policies and procedures, changes in the nature and volume of the loan 
portfolio, changes in the experience, ability and depth of lending management and staff, changes in the volume and severity of past due loans, 
nonaccrual loans and adversely classified loans, changes in the quality of the credit review function, changes in the value of underlying 
collateral dependent loans, existence and effect of any concentrations of credit and any changes in such, effect of other factors such as 
competition and legal and regulatory requirements, and historical loss rate information.

F-23

Significant judgment was required by management in the selection and measurement of qualitative factor adjustments. Accordingly, 
performing audit procedures to evaluate the Company’s estimated ACL involved a high degree of auditor judgment and required significant 
effort, including the involvement of professionals with specialized skill and knowledge.

Our audit procedures related to the Company’s estimate of the ACL included, but were not limited to, the following:

● We tested the design and operating effectiveness of management's controls over the determination of the qualitative factor 

adjustments.

● We obtained an understanding of management's process for determining the need for qualitative factor adjustments, identifying

appropriate factors, and measuring the direction and magnitude of the adjustment.

● We evaluated management's rationale for determining qualitative adjustments were relevant and warranted for each loan segment

and assessed the measurement of qualitative factor adjustments applied by management.

● Where applicable, we tested the accuracy and completeness of data used by management in the measurement of qualitative factor

adjustments or vouched factors to relevant external data sources.

● We assessed changes in qualitative factors against overall trends in credit quality within the Company and broader trends within the 

industry and local and national economies to evaluate reasonableness of management’s qualitative factor adjustments.

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting as of December 31, 2024 of Mercantile Bank Corporation (the "Company"), 
based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the 
Treadway Commission (the “COSO framework”). In our opinion, the Company maintained, in all material respects, effective internal control 
over financial reporting as of December 31, 2024, based on the criteria established in the COSO framework.

We also have audited the accompanying consolidated balance sheets of the Company as of December 31, 2024 and 2023, the related
consolidated statements of income, comprehensive income (loss), stockholders' equity, and cash flows for each of the years in the two-year 
period ended December 31, 2024, and the related notes (collectively referred to as the “consolidated financial statements”), in accordance 
with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”). Our report dated March 3, 2025, 
expressed an unqualified opinion.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the 
effectiveness of internal control over financial reporting, included in the accompanying Report by Mercantile Bank Corporation’s 
Management on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over 
financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with 
respect to the Company in accordance with U.S. federal securities laws and applicable rules and regulations of the Securities and Exchange 
Commission and the PCAOB.

We conducted our audit of internal control over financial reporting in accordance with the standards of the PCAOB. Those standards require 
that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was 
maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal 
control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating 
effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered 
necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of 
financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting 
principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of 
records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide 
reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally 
accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of 
management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized 
acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any 
evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or 
that the degree of compliance with the policies or procedures may deteriorate.

ended December 31, 2022, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the 
consolidated financial statements present fairly, in all material respects, the results of the Company’s operations and its cash flows for the

Change in Accounting Principle

As discussed in Note 1 to the consolidated financial statements, the Company has changed its method of accounting for the recognition and 
measurement of credit losses as of January 1, 2022 due to the adoption of ASC Topic 326, Financial Instruments – Credit Losses.

Basis for Opinion

REPORT BY MERCANTILE BANK CORPORATION’S MANAGEMENT
ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Management is responsible for establishing and maintaining an effective system of internal control over financial reporting that is designed to 
produce reliable financial statements presented in conformity with generally accepted accounting principles. There are inherent limitations in 
the effectiveness of any system of internal control. Accordingly, even an effective system of internal control can provide only reasonable 
assurance with respect to financial statement preparation.

Management assessed the Company’s system of internal control over financial reporting that is designed to produce reliable financial 
statements presented in conformity with generally accepted accounting principles as of December 31, 2024. This assessment was based on 
criteria for effective internal control over financial reporting described in Internal Control – Integrated Framework (2013) issued by the 
Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, management believes that, as of December 
31, 2024, Mercantile Bank Corporation maintained an effective system of internal control over financial reporting that is designed to produce 
reliable financial statements presented in conformity with generally accepted accounting principles based on those criteria.

The Company’s independent auditors have issued an audit report on the effectiveness of the Company’s internal control over financial 
reporting as found on page F-25.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
December 31, 2024

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation: The consolidated financial statements include the accounts of Mercantile Bank Corporation (“Mercantile”) and 
its subsidiaries, Mercantile Bank (“our bank”) and Mercantile Community Partners LLC ("MCP"), and of Mercantile Insurance Center, Inc. 
(“our insurance company”), a subsidiary of our bank, after elimination of significant intercompany transactions and accounts.

Mercantile has five separate business trusts: Mercantile Bank Capital Trust I, Firstbank Capital Trust I, Firstbank Capital Trust II, Firstbank 
Capital Trust III and Firstbank Capital Trust IV (“our trusts”). Our trusts were formed to issue trust preferred securities. We issued 
subordinated debentures to our trusts in return for the proceeds raised from the issuance of the trust preferred securities. Our trusts are not 
consolidated, but instead we report the subordinated debentures issued to the trusts as liabilities.

Nature of Operations: Mercantile was incorporated on July 15, 1997 to establish and own the bank based in Grand Rapids, Michigan. Our 
bank began operations on December 15, 1997. We completed the merger of Firstbank Corporation (“Firstbank”), a Michigan corporation 
with approximately $1.5 billion in total assets and 46 branch locations, into Mercantile as of June 1, 2014.

Mercantile is a financial holding company whose principal activity is the ownership and management of our bank. Our bank is a community-
based financial institution. Our bank’s primary deposit products are checking, savings, and term certificate accounts, and its primary lending 
products are commercial loans, residential mortgage loans, and instalment loans. Substantially all loans are secured by specific items of 
collateral, including business assets, real estate or consumer assets. Commercial loans are expected to be repaid from cash flow from 
operations of businesses. Real estate loans are secured by commercial or residential real estate. We have no material foreign loans or 
significant overdraft balances. Our bank’s loan accounts and retail deposits are primarily with customers located in the communities in which 
we have bank office locations. As an alternative source of funds, our bank has also issued certificates of deposit to depositors outside of its 
primary market areas.

Our insurance company acquired an existing shelf insurance agency effective April 15, 2002. An Agency and Institution Agreement was 
entered into among our insurance company, our bank and Hub International for the purpose of providing programs of mass marketed 
personal lines of insurance. Insurance product offerings include private passenger automobile, homeowners, personal inland marine, boat 
owners, recreational vehicle, dwelling fire, umbrella policies, small business and life insurance products, all of which are provided by and 
written through companies that have appointed Hub International as their agent. To date, we have not provided the insurance products noted 
above and currently have no plans to do so.

We have evaluated subsequent events for potential recognition and/or disclosure through the date these financial statements were issued.

Operating Segments: We conduct our operations through a single business segment, which derives interest and noninterest income through 
our banking products and services and investment securities. All of our income relates to our operations in the United States.

Pursuant to Financial Accounting Standards Codification 280, Segment Reporting, operating segments represent components of an enterprise 
for which separate financial information is available that is regularly evaluated by the chief operating decision makers in determining how to 
allocate resources and assessing performance.

Our chief operating decision makers, which include our Chief Executive Officer, Chief Financial Officer, and Chief Operating Officer, 
evaluate interest and noninterest income streams and credit losses from our various products and services, while expense activities, including 
interest expense and noninterest expense, are managed, and financial performance is evaluated, on a Company-wide basis. As a result, 
detailed profitability information for each interest and noninterest income stream is not used by our chief operating decision makers to 
allocate resources or in assessing performance. Rather, our chief operating decision makers use consolidated net income to assess 
performance by comparing it to and monitoring against budgeted and prior year results. This information is used to manage resources to drive 
business and net income growth, including investment in key strategic priorities, as well as determine our ability to return capital to 
shareholders. Segment assets represent total assets on our Consolidated Balance Sheets and segment net income represents net income on our 
Consolidated Statements of Income.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Use of Estimates: To prepare financial statements in conformity with accounting principles generally accepted in the United States of 
America, management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts 
reported in the financial statements and the disclosures provided, and actual results could differ. The allowance for credit losses and the fair 
value measurements are particularly subject to change.

Cash and Cash Equivalents and Cash Flow Reporting: Cash and cash equivalents include cash on hand, demand deposits with other financial 
institutions, short-term investments and federal funds sold. Cash flows are reported net for customer loan and deposit transactions, interest-
earning deposits invested with other financial institutions and short-term borrowings with maturities of 90 days or less.

Debt Securities: Debt securities classified as held to maturity are carried at amortized cost when management has the positive intent and 
ability to hold them to maturity. Debt securities available for sale consist of bonds which might be sold prior to maturity due to a number of 
factors, including changes in interest rates, prepayment risks, yield, availability of alternative investments or liquidity needs. Debt securities 
classified as available for sale are reported at their fair value. For available for sale debt securities in an unrealized loss position, we first 
assess whether we intend to sell, or if it is more likely than not that we will be required to sell the security before recovery of the amortized 
cost basis. If either of the criteria regarding intent or requirement to sell is met, the debt security’s amortized cost basis is written down to fair 
value through income with the establishment of an allowance. For debt securities available for sale that do not meet the aforementioned 
criteria, we evaluate whether any decline in fair value is due to credit loss factors. In making this assessment, we consider any changes to the 
rating of the security by a rating agency and adverse conditions specifically related to the issuer of the security, among other factors. If this 
assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the 
amortized cost basis of the security. If the present value of the cash flows expected to be collected is less than the amortized cost basis, a 
credit loss exists and an allowance is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost 
basis. Any impairment that has not been recorded through an allowance is recognized in other comprehensive income.

Changes in the allowance are recorded as provisions for (or reversal of) credit loss expense. Losses are charged against the allowance when 
the collectability of an available for sale debt security is confirmed or when either of the criteria regarding intent or requirement to sell is met. 
At December 31, 2024, there was no allowance related to the available for sale debt securities portfolio.

Interest income includes amortization of purchase premiums and accretion of discounts. Premiums and discounts on securities are amortized 
or accreted on the level-yield method without anticipating prepayments, except for mortgage-backed securities where prepayments are 
anticipated. Gains and losses on sales are recorded on the trade date and determined using the specific identification method.

Accrued interest receivable on available for sale debt securities totaling $3.6 million and $2.6 million at December 31, 2024 and 2023, 
respectively, was reported in other assets on the Consolidated Balance Sheets. Management has made the accounting policy election to 
exclude accrued interest receivable on available for sale securities from the estimate of credit losses as accrued interest is written off in a 
timely manner when deemed uncollectible.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Federal Home Loan Bank Stock: Our bank owns stock of the Federal Home Loan Bank of Indianapolis ("FHLBI"). The FHLBI is a 
governmental sponsored entity that requires banks to invest in their nonmarketable stock as a condition of membership. FHLBI members are 
required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLBI 
stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. 
The ability to redeem the shares owned is dependent on the redemption practice of the FHLBI. Dividends are recorded in income on the ex-
dividend date.

Loans: Loans that we have the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the principal 
balance outstanding adjusted for partial charge-offs and the allowance, net of deferred loan fees and costs.  Interest income on loans is 
accrued over the term of the loans primarily using the simple interest method based on the principal balance outstanding. Accrued interest is 
included in other assets in the Consolidated Balance Sheets. Loan origination fees and certain direct costs incurred to extend credit are 
deferred and amortized over the term of the loan or loan commitment period as an adjustment to the related loan yield.

Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and 
recognized in interest income using the level-yield method without anticipating prepayments. Net unamortized deferred loan costs amounted 
to $2.2 million and $2.4 million at December 31, 2024 and 2023, respectively.

Interest income on commercial loans and mortgage loans is discontinued at the time the loan is 90 days delinquent unless the loan is well-
secured and in process of collection. Consumer and credit card loans are typically charged off no later than when they are 120 days past due. 
Past due status is based on the contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged off at an earlier date if 
collection of principal and interest is considered doubtful. All interest accrued but not received for loans placed on nonaccrual is reversed 
against interest income. Interest received on such loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return 
to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future 
payments are reasonably assured.

Commercial Loan Participations: As part of our credit risk administration practices and to manage exposure limits, we engage in commercial 
loan participations with other financial institutions from time-to-time. In all instances, the commercial loans are participated at par with no 
loan yield adjustments; therefore, no gain or loss on sale, or servicing right, is recorded. We retain a large portion of the loan exposure and 
continue to service the lending relationship. Commercial loan participations aggregated $48.6 million and $46.7 million as of December 31, 
2024 and 2023, respectively.

Loans Held for Sale: Mortgage loans originated and intended for sale in the secondary market are carried at the lower of aggregate cost or fair 
value, as determined by outstanding commitments from investors. Net unrealized losses, if any, are recorded as a valuation allowance and 
charged to earnings. Mortgage loans held for sale are generally sold with servicing rights retained. Gains and losses on sales of mortgage 
loans are based on the difference between the selling price and the carrying value of the related mortgage loan sold, which is reduced by the 
cost allocated to the servicing right. We generally lock in the sale price to the purchaser of the mortgage loan at the same time we make an 
interest rate commitment to the borrower.

included in mortgage banking activities in the Consolidated Statements of Income. The net balance of mortgage loan derivatives aggregated 
to an asset of $0.1 million at December 31, 2024 and a liability of less than $0.1 million as of December 31, 2023.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
December 31, 2024

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Mortgage Banking Activities: Mortgage loan servicing rights are recognized as assets based on the allocated value of retained servicing rights 
on mortgage loans sold. Mortgage loan servicing rights are carried at the lower of amortized cost or fair value and are expensed in proportion 
to, and over the period of, estimated net servicing revenues. Impairment is evaluated based on the fair value of the rights using groupings of 
the underlying mortgage loans as to interest rates. Any impairment of a grouping is reported as a valuation allowance.

Servicing fee income is recorded for fees earned for servicing mortgage loans. The fees are based on a contractual percentage of the 
outstanding principal or a fixed amount per loan and are recorded as income when earned. Amortization of mortgage loan servicing rights is 
netted against mortgage loan servicing income and recorded in mortgage banking activities in the Consolidated Statements of Income.

Accounting for mortgage servicing rights is based on the class of mortgage servicing rights. We have identified four classes of mortgage 
servicing rights based on the initial term of the underlying mortgage loans: 10 years, 15 years, 20 years and 30 years. We distinguish between 
these classes based on the differing sensitivities to the change in value from changes in mortgage interest rates. Mortgage servicing rights are 
initially recorded at fair value, and then are accounted for using the amortization method. Netted against mortgage banking income, mortgage 
servicing rights amortization expense is reported as noninterest income in the Consolidated Statements of Income. Mortgage servicing rights 
amortization is determined by amortizing the mortgage servicing rights balance in proportion to, and over the period of, the estimated future 
net servicing income of the underlying mortgage loans.

Interest rate risk, prepayment risk and default risk are inherent in mortgage servicing rights valuations. Interest rate changes largely drive 
prepayment rates. Refinance activity generally increases as interest rates decline. A significant decrease in interest rates beyond expectation 
could cause a decline in the value of mortgage servicing rights. On the contrary, borrowers are less likely to refinance or prepay their 
mortgage loans if interest rates increase, which would extend the duration of the underlying mortgage loans and the associated mortgage 
servicing rights value would likely rise. Because of these risks, discount rates and prepayment speeds are used to estimate the fair value of 
mortgage servicing rights.

Troubled Debt Restructurings: The accounting guidance for troubled debt restructurings by creditors in Subtopic 310-40, Receivables –
Troubled Debt Restructurings by Creditors was eliminated upon our adoption of ASU No. 2022-02 Financial Instruments – Credit Losses 
(Topic 326): Troubled Debt Restructurings and Vintage Disclosures, which was effective January 1, 2023. ASU No. 2022-02 eliminated 
troubled debt restructurings recognition and measurement guidance and, instead, requires that entities evaluate (consistent with the 
accounting for other loan modifications) whether the modification represents a new loan or a continuation of an existing loan.

In accordance with previous accounting guidance, loans modified as troubled debt restructurings were, by definition, considered to be 
impaired loans. Impairment for these loans were measured on a loan-by-loan basis. Certain loans modified as troubled debt restructurings 
may have been previously measured for impairment under a general allowance methodology (i.e., pooling), thus at the time the loan 
was modified as a troubled debt restructuring, the allowance may have been impacted by the difference between the results of these two 
measurement methodologies. Loans modified as troubled debt restructurings that subsequently default were factored into the determination 
of the allowance in the same manner as other defaulted loans. Our bank has chosen to continue to individually assess loans previously 
identified as troubled debt restructurings for allowance for credit losses purposes; thus, there was no change to the allowance for credit losses 
upon adoption.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Allowance for Credit Losses (“allowance”): The allowance is a valuation account that is deducted from the loans’ amortized cost basis to 
present the net amount expected to be collected on the loans. The allowance is increased by provision expense and decreased by charge-offs, 
net of recoveries of amounts previously charged-off. Loans are charged-off against the allowance when we believe the uncollectibility of a 
loan balance is confirmed. The allowance is measured on a collective pool basis when similar risk characteristics exist and on an individual 
basis when a loan exhibits unique risk characteristics that differentiate the loan from other loans within the loan segments. Loan segments are 
further discussed in Note 3 - Loans and Allowance for Credit Losses.

The “remaining life methodology” is utilized for substantially all loan pools. This non-discounted cash flow approach projects an estimated 
future amortized cost basis based on current loan balance and repayment terms. Our historical loss rate is then applied to future loan balances 
at the instrument level based on remaining contractual life adjusted for amortization, prepayment and default to develop a baseline lifetime 
loss. The baseline lifetime loss is adjusted for changes in macroeconomic conditions over the reasonable and supportable forecast and 
reversion periods via a series of macroeconomic forecast inputs, such as gross domestic product, unemployment rates, interest rates, credit 
spreads, stock market volatility and property price indices, to quantify the impact of current and forecasted economic conditions on expected 
loan performance.

Reasonable and supportable economic forecasts have to be incorporated in determining expected credit losses. The forecast period represents 
the time frame from the current period end through the point in time that we can reasonably forecast and support entity and environmental 
factors that are expected to impact the performance of our loan portfolio. Ideally, the economic forecast period would encompass the 
contractual terms of all loans; however, the ability to produce a forecast that is considered reasonable and supportable becomes more difficult 
or may not be possible in later periods. The contractual term generally excludes potential extensions, renewals and modifications.

Subsequent to the end of the forecast period, we revert to historical loan data based on an ongoing evaluation of each economic forecast in 
relation to then current economic conditions as well as any developing loan loss activity and resulting historical data. We are not required to 
develop and use our own economic forecast model, and elect to utilize economic forecasts from third-party providers that analyze and 
develop forecasts of the economy for the entire United States at least quarterly.

During each reporting period, we also consider the need to adjust the historical loss rates as determined to reflect the extent to which we 
expect current conditions and reasonable and supportable economic forecasts to differ from the conditions that existed for the period over 
which the historical loss information was determined. These qualitative adjustments may increase or decrease our estimate of expected future 
credit losses.

Our qualitative factors include:

o
o
o
o
o
o
o
o
o

Changes in lending policies and procedures
Changes in the nature and volume of the loan portfolio and in the terms of loans
Changes in the experience, ability and depth of lending management and other relevant staff
Changes in the volume and severity of past due loans, nonaccrual loans and adversely classified loans
Changes in the quality of the loan review program
Changes in the value of underlying collateral dependent loans
Existence and effect of any concentrations of credit and any changes in such
Effect of other factors such as competition and legal and regulatory requirements
Local or regional conditions that depart from the conditions and forecasts for the entire country

The estimation of future credit losses should reflect consideration of all significant factors that affect the collectibility of the loan portfolio at 
each evaluation date. While our methodology considers both the historical loss rates as well as the traditional qualitative factors, there may be 
instances or situations where additional qualitative factors need to be considered. Effective January 1, 2022, we established a historical loss 
information factor to address the relatively low level of loan losses during the look-back period.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Accrued interest receivable on loans totaling $17.3 million and $16.9 million as of December 31, 2024 and 2023, respectively, is included in 
other assets on the Consolidated Balance Sheets. We elected not to measure an allowance for accrued interest receivable and instead elected 
to reverse interest income on loans that are placed on nonaccrual status, which is generally when the loan becomes 90 days past due, or 
earlier if we believe the collection of interest is doubtful. We believe this policy results in the timely reversal of uncollectible interest.

Identified problem loans, which exhibit characteristics (financial or otherwise) that could cause the loans to become nonperforming or require 
restructuring in the future, are included on an internal watch list. Senior management and the Board of Directors review this list regularly. In 
some cases, we may determine that an individual loan exhibits unique risk characteristics that differentiate the loan from other loans within 
the loan segments. In such cases, the loans are evaluated for expected credit losses on an individual basis and excluded from the collective 
evaluation. Specific reserve allocations of the allowance for credit losses are determined by analyzing the borrower’s ability to repay amounts 
owed and collateral deficiencies, among other things.

For individually analyzed loans that are deemed to be collateral dependent loans, we adopted the practical expedient to measure the 
allowance based on the fair value of collateral. The allowance is calculated on an individual loan basis based on the shortfall between the fair 
value of the loan’s collateral and its recorded principal balance. If the fair value of the collateral exceeds the recorded principal balance, no 
allowance is required. Fair value estimates of collateral on individually analyzed 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.

We are also required to consider expected credit losses associated with loan commitments over the contractual period in which we are 
exposed to credit risk on the underlying commitments unless the obligation is unconditionally cancellable by us. Any allowance for off-
balance sheet credit exposures is reported as an other liability on our Consolidated Balance Sheets and is increased or decreased via other 
noninterest expense on our Consolidated Statement of Income. The calculation includes consideration of the likelihood that funding will 
occur and forecasted credit losses on commitments expected to be funded over their estimated lives. The allowance is calculated using the 
same aggregate reserve rates calculated for the funded portion of loans at the portfolio level applied to the amount of commitments expected 
to be funded.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Transfers of Financial Assets: Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. 
Control over transferred assets is deemed to be surrendered when: (1) the assets have been isolated from our bank and put presumptively 
beyond the reach of the transferor and its creditors, even in bankruptcy or other receivership, (2) the transferee obtains the right (free of 
conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) our bank does not 
maintain effective control over the transferred assets through an agreement to repurchase them before their maturity or the ability to 
unilaterally cause the holder to return specific assets. Our transfers of financial assets are generally limited to commercial loan participations 
sold and residential mortgage loans sold in the secondary market.

Premises and Equipment: Land is carried at cost. Premises and equipment are stated at cost less accumulated depreciation. Buildings and 
related components are depreciated using the straight-line method with useful lives ranging from 5 to 33 years. Furniture, fixtures and 
equipment are depreciated using the straight-line method with useful lives ranging from 3 to 7 years. Maintenance, repairs and minor 
alterations are charged to current operations as expenditures occur and major improvements are capitalized. Premises and equipment are 
reviewed for impairment when events indicate their carrying amount may not be recoverable based on future undiscounted cash flows. If 
impaired, the assets are recorded at the lower of carrying value or fair value.

Foreclosed Assets: Assets acquired through or in lieu of foreclosure are initially recorded at their estimated fair value net of estimated selling
costs, establishing a new cost basis. If fair value subsequently declines, a valuation allowance is recorded through noninterest expense, as are 
collection and operating costs after acquisition. We had no foreclosed assets as of December 31, 2024. Foreclosed assets, included in other 
assets in the Consolidated Balance Sheets, totaled $0.2 million as of December 31, 2023.

Bank Owned Life Insurance: Our bank has purchased life insurance policies on certain key officers. Bank owned life insurance is recorded at 
its cash surrender value, or the amount that can be realized. Increases in the net cash surrender value of the policies, as well as insurance 
proceeds received, are recorded as noninterest income on the Consolidated Statements of Income and are not subject to income taxes.

Goodwill: The acquisition method of accounting requires that assets and liabilities acquired in a business combination to be recorded at fair 
value as of the acquisition date. The valuation of assets and liabilities often involves estimates based on third-party valuations or internal 
valuations based on discounted cash flow analyses or other valuation techniques, all of which are inherently subjective. This typically results 
in goodwill, the amount by which the cost of net assets acquired in a business combination exceeds their fair value, which is subject to 
impairment testing at least annually. We review goodwill for impairment on an annual basis as of October 1 or more often if events or 
circumstances indicate that it is more-likely-than-not that the fair value of a reporting unit is below its carrying value. Based on our annual 
impairment analysis of goodwill as of October 1, it was determined that the fair value was in excess of its respective carrying value as of 
October 1, 2024; therefore, goodwill is considered not impaired.

Repurchase Agreements: Our bank sells certain securities under agreements to repurchase. The agreements are treated as collateralized 
financing transactions, with the obligations to repurchase the securities sold reflected as liabilities and the securities underlying the 
agreements remaining in assets in the Consolidated Balance Sheets.

NOTE 1 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Financial Instruments and Loan Commitments: Financial instruments include off-balance-sheet credit instruments, such as commitments to 
make loans and commercial letters of credit, issued to meet customer financing needs. The face amount for these items represents the 
exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded. 
Instruments, such as standby letters of credit, that are considered financial guarantees are recorded at fair value. Reserves for unfunded 
commitments are recorded as an other liability on our Consolidated Balance Sheets.

Stock-Based Compensation: Compensation cost for equity-based awards is measured on the grant date based on the fair value of the award 
on that date and recognized over the requisite service period, net of estimated forfeitures. Fair value of stock option awards is estimated using
a closed option valuation (Black-Scholes) model. Fair value of restricted stock awards is based upon the quoted market price of the common 
stock on the date of grant.

Revenue from Contracts with Customers: We record revenue from contracts with customers in accordance with Accounting Standards 
Codification Topic 606, “Revenue from Contracts with Customers” (“Topic 606”). Under Topic 606, we must identify the contract with a 
customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the 
performance obligations in the contract, and recognize revenue when (or as) we satisfy a performance obligation. Significant revenue has not 
been recognized in the current reporting period that results from performance obligations satisfied in previous periods.

Our primary sources of revenue are derived from interest and dividends earned on loans, securities and other financial instruments that are 
not within the scope of Topic 606. We have evaluated the nature of our contracts with customers and determined that further disaggregation 
of revenue from contracts with customers into more granular categories beyond what is presented in the Consolidated Statements of Income 
was not necessary.

We generally satisfy our performance obligations on contracts with customers as services are rendered, and the transaction prices are 
typically fixed and charged either on a periodic basis (generally monthly) or based on activity. Because performance obligations are satisfied 
as services are rendered and the transaction prices are fixed, there is little judgment involved in applying Topic 606 that significantly affects 
the determination of the amount and timing of revenue from contracts with customers.

The following table depicts our sources of noninterest income presented in the Consolidated Statements of Income for the years ended 
December 31, 2024, 2023 and 2022 that are scoped within Topic 606:

Service Charges on Deposit and Sweep Accounts: We earn fees from deposit and sweep customers for account maintenance, transaction-
based and overdraft services. Account maintenance fees, which relate primarily to monthly maintenance, are earned over the course of the 
month reflecting the period over which we satisfy the performance obligation. Transaction-based fees, which include services such as stop 
payment and returned item charges, are recognized at the time the transaction is executed as that is the point in time we fulfill the customer 
request. Service charges on deposit and sweep accounts are withdrawn from the customer account balance.

NOTE 1 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Credit and Debit Card Fees: We earn interchange income on our cardholder debit and credit card usage. Interchange income is primarily 
comprised of fees whenever our debit and credit cards are processed through card payment networks such as Visa. Interchange fees from 
cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction
processing services provided to the cardholder.

Payroll Processing Fees: We earn fees from providing payroll processing services for our commercial clients. Fees are assessed for 
processing weekly or bi-weekly payroll files, reports and documents, as well as year-end tax-related files, reports and documents. Fees are 
recognized and collected as payroll processing services are completed for each payroll run and year-end processing activities.

Customer Service Fees: We earn fees by providing a variety of other services to our customers, such as wire transfers, check ordering, sales 
of cashier checks and money orders, and rentals of safe deposit boxes. Generally, fees are recognized and collected daily, concurrently with 
the point in time we fulfill the customer request. Safe deposit box rentals are on annual contracts, with fees generally earned at the time of the 
contract signing or renewal. Customer service fees are recorded as other noninterest income on our Consolidated Statements of Income.

Advertising Costs: Advertising costs are expensed as incurred.

Income Taxes: Income tax expense is the total of the current year income tax due or refundable, the change in deferred income tax assets and 
liabilities, and any adjustments related to unrecognized tax benefits. Deferred income tax assets and liabilities are recognized for the tax 
consequences of temporary differences between the carrying amounts and tax bases of assets and liabilities, computed using enacted tax rates 
applicable to future years. A valuation allowance, if needed, reduces deferred income tax assets to the amount expected to be realized.

Fair Values of Financial Instruments: Fair values of financial instruments are estimated using relevant market information and other 
assumptions. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments 
and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could 
significantly affect the estimates. The fair value estimates of existing on- and off-balance sheet financial instruments do not include the value 
of anticipated future business or the values of assets and liabilities not considered financial instruments.

Earnings Per Share: Basic earnings per share is based on the weighted average number of common shares and participating securities 
outstanding during the period. Diluted earnings per share include the dilutive effect of additional potential common shares issuable under our 
stock-based compensation plans using the treasury stock method. Our unvested stock awards, which contain non-forfeitable rights to 
dividends whether paid or unpaid (i.e., participating securities), are included in the number of shares outstanding for both basic and diluted 
earnings per share calculations. In the event of a net loss, our unvested stock awards are excluded from the calculations of both basic and 
diluted earnings per share.

Comprehensive Income (Loss): Comprehensive income (loss) consists of net income and other comprehensive income (loss). Accumulated 
other comprehensive gain/(loss) includes unrealized gains and losses on securities available for sale. Accumulated other comprehensive 
gain/(loss) was comprised of the following as of December 31, 2024, 2023 and 2022:

NOTE 1 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Derivatives: Derivative financial instruments are recognized as assets or liabilities at fair value. The accounting for changes in the fair value 
of derivatives depends on the use of the derivatives and whether the derivatives qualify for hedge accounting. Used as part of our asset and 
liability management to help manage interest rate risk, our derivatives have historically generally consisted of interest rate swap agreements 
that qualified for hedge accounting. We do not use derivatives for trading purposes. Changes in the fair value of derivatives that are 
designated, for accounting purposes, as a hedge of the variability of cash flows to be received on various assets and liabilities and are 
effective are reported in other comprehensive income. They are later reclassified into earnings in the same periods during which the hedged 
transaction affects earnings and are included in the line item in which the hedged cash flows are recorded. If hedge accounting does not 
apply, changes in the fair value of derivatives are recognized immediately in current earnings as interest income or expense. We had no 
derivative instruments designated as hedges as of December 31, 2024 and 2023.

Contingencies: Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities
when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. We do not believe there are any such 
matters outstanding that would have a material effect on the financial statements.

Recent Accounting Changes Adopted: ASU No. 2023-07, Segment Reporting (Topic 323): Improvements to Reportable Segment 
Disclosures. This ASU enhances disclosures of significant segment expenses by requiring entities to disclose significant segment expenses 
regularly provided to the chief operating decision maker, extend certain annual disclosures to interim periods, and permit more than one 
measure of segment profit or loss to be reported under certain conditions. This ASU took effect for annual reporting periods beginning after 
December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. We have adopted the standard and included 
the required disclosures in our financial statements.

ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This ASU modifies the rules on income tax 
disclosures to require entities to disclose (1) specific categories in the rate reconciliation, (2) the income or loss from continuing operations 
before income tax expense or benefit (separated between domestic and foreign) and (3) income tax expense or benefit from continuing 
operations (separated by federal, state and foreign). This ASU also requires entities to disclose their income tax payments to international, 
federal, state and local jurisdictions, among other changes. This ASU takes effect in reporting periods beginning after December 15, 2024, 
with early adoption permitted. We have adopted the standard and included the required disclosures in our financial statements.

NOTE 2 – SECURITIES (Continued)

We evaluate securities in an unrealized loss position at least quarterly. Consideration is given to the financial condition of the issuer, and the 
intent and ability we have to retain our investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair 
value. For those debt securities whose fair value is less than their amortized cost basis, we also consider our intent to sell the security, 
whether it is more likely than not that we will be required to sell the security before recovery and if we do not expect to recover the entire 
amortized cost basis of the security. In analyzing an issuer’s financial condition, we may consider whether the securities are issued by the 
federal government or its agencies, whether downgrades by bond rating agencies have occurred and the results of reviews of the issuer’s 
financial condition.

At December 31, 2024, 843 debt securities with estimated fair values totaling $680 million had unrealized losses aggregating $63.8 million. 
At December 31, 2023, 641 debt securities with estimated fair values totaling $549 million had unrealized losses aggregating $66.1 million. 
At December 31, 2024, unrealized losses aggregating $53.6 million were attributable to bonds issued or guaranteed by agencies of the U.S. 
federal government, while unrealized losses totaling $10.2 million were associated with bonds issued by state-based municipalities. After 
considering the issuers of the bonds and taking into account the fact that no municipal issuer had been subject to a credit rating downgrade by 
bond credit rating agencies, we determined that the unrealized losses were due to changing interest rate environments. As we do not intend to 
sell our debt securities before recovery of their cost basis and we believe it is more likely than not that we will not be required to sell our debt 
securities before recovery of the cost basis, no unrealized losses are deemed to represent credit losses.

The amortized cost and fair values of debt securities at December 31, 2024, by maturity, are shown in the following table. The contractual 
maturity is utilized for U.S. Government agency debt obligations and municipal bonds. Expected maturities may differ from contractual 
maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Securities not due 
at a single maturity date, primarily mortgage-backed securities, are shown separately.

NOTE 3 – LOANS AND ALLOWANCE FOR CREDIT LOSSES

Commercial loans are divided among five segments based primarily on collateral type, risk characteristics, and primary and secondary 
sources of repayment. These segments are then further stratified based on the commercial loan grade that is assigned using our standard loan 
grading paradigm. Retail loans are divided into one of two groups based on risk characteristics and source of repayment. Our allowance for 
credit loss pools are consistent with those used for loan note disclosure purposes.

Our loan portfolio segments as of December 31, 2024 were as follows:

o

Commercial Loans

■ Commercial and Industrial: Risks to this loan category include industry concentration and the practical limitations 

associated with monitoring the condition of the collateral which often consists of inventory, accounts receivable, and 
other non-real estate assets. Equipment and inventory obsolescence can also pose a risk. Declines in general 
economic conditions and other events can cause cash flows to fall to levels insufficient to service debt.

■ Owner Occupied Commercial Real Estate: Risks to this loan category include industry concentration and the inability 
to monitor the condition of the collateral. Declines in general economic conditions and other events can cause cash 
flows to fall to levels insufficient to service debt. Also, declines in real estate values and lack of suitable alternative 
use for the properties are risks for loans in this category.

■ Non-Owner Occupied Commercial Real Estate: Loans in this category are susceptible to declines in occupancy rates, 
business failure, and general economic conditions. Also, declines in real estate values and lack of suitable alternative 
use for the properties are risks for loans in this category.

■ Multi-Family and Residential Rental: Risks to this loan category include industry concentration and the inability to 
monitor the condition of the collateral. Loans in this category are susceptible to weakening general economic 
conditions and increases in unemployment rates, as well as market demand and supply of similar property and the 
resulting impact on occupancy rates, market rents, cash flow, and income-based real estate values. Also, the lack of a 
suitable alternative use for the properties is a risk for loans in this category.

■ Vacant Land, Land Development and Residential Construction: Risks common to commercial construction loans are 
cost overruns, changes in market demand for property, inadequate long-term financing arrangements, and declines in 
real estate values. Residential construction loans are susceptible to those same risks as well as those associated with 
residential mortgage loans. Changes in market demand for property could lead to longer marketing times resulting in 
higher carrying costs, declining values, and higher interest rates.

o

Retail Loans
■

1-4 Family Mortgages: Residential mortgage loans are susceptible to weakening general economic conditions and 
increases in unemployment rates and declining real estate values.

■ Other Consumer Loans: Risks common to these loans include regulatory risks, unemployment, and changes in local 

economic conditions as well as the inability to monitor collateral consisting of personal property.

During 2023, we changed the segmentation of credit cards to business customers from other consumer loans to commercial and industrial 
loans. This division of the credit card balances was done to better align the risk characteristics of the portfolio, which include the customer 
type and source of repayment. Credit cards to business customers totaled $19.1 million and $17.8 million as of December 31, 2024 and 
2023, respectively. We also changed the segmentation of home equity lines of credit from 1-4 family mortgage loans to other consumer 
loans during the year ended December 31, 2023. Home equity lines of credit share many of the same risk characteristics of both segments, 
however, losses are primarily driven by a lack of underlying collateral value during distressed situations as many of the loans are in a 
second lien position, and thus, best segmented within the other consumer portfolio. Home equity lines of credit totaled $52.0 million and 
$38.1 million as of December 31, 2024 and 2023, respectively.

Nonaccrual loans represent the entire balance of collateral dependent loans. As of December 31, 2024 and 2023, all collateral dependent 
loans were secured by real estate, with the exception of those classified as commercial and industrial, which were secured by accounts 
receivable, inventory, and equipment. Interest income recognized on nonaccrual loans totaled $0.3 million in 2024, $0.2 million 
in 2023 and less than $0.1 million in 2022, reflecting the collection of interest at the time of principal pay-off.

Credit Quality Indicators. We utilize a comprehensive grading system for our commercial loans. All commercial loans are graded on a ten 
grade rating system. The rating system utilizes standardized grade paradigms that analyze several critical factors such as cash flow, operating 
performance, financial condition, collateral, industry condition and management. All commercial loans are reviewed and graded at inception 
and, if appropriate, re-graded at various intervals thereafter. The risk assessment for retail loans is primarily based on the type of collateral.

Loans by credit quality indicators were as follows as of December 31, 2024:

NOTE 3 – LOANS AND ALLOWANCE FOR CREDIT LOSSES (Continued)

All commercial loans are graded using the following criteria:

Grade 1.

“Exceptional” Loans with this rating contain very little, if any, risk.

Grade 2.

Grade 3.

Grade 4.

Grade 5.

Grade 6.

Grade 7.

Grade 8.

“Outstanding” Loans with this rating have excellent and stable sources of repayment and conform to bank policy and 
regulatory requirements.

“Very Good” Loans with this rating have strong sources of repayment and conform to bank policy and regulatory 
requirements. These are loans for which repayment risks are acceptable.

“Good” Loans with this rating have solid sources of repayment and conform to bank policy and regulatory requirements. 
These are loans for which repayment risks are modest.

“Acceptable” Loans with this rating exhibit acceptable sources of repayment and conform with most bank policies and all 
regulatory requirements. These are loans for which repayment risks are satisfactory.

“Monitor” Loans with this rating are considered to have emerging weaknesses which may include negative current cash 
flow, high leverage, or operating losses. Generally, if further deterioration is observed, these credits will be downgraded to
the criticized asset report.

“Special Mention” Loans with this rating have potential weaknesses that deserve management’s close attention. If left 
uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan at some future 
date.

“Substandard” Loans with this rating are inadequately protected by current sound net worth, paying capacity of the 
obligor, or of the pledged collateral, if any. A Substandard loan normally has one or more well-defined weaknesses that 
jeopardize the repayment of the debt. They are characterized by the distinct possibility of loss if the deficiencies are not 
corrected.

Grade 9.

“Doubtful” Loans with this rating exhibit all the weaknesses inherent in the Substandard classification and where 
collection or liquidation in full is highly questionable and improbable.

Grade 10.

“Loss” Loans with this rating are considered uncollectable, and of such little value that continuance as an active asset is 
not warranted.

The primary risk elements with respect to commercial loans are the financial condition of the borrower, the sufficiency of collateral, and 
timeliness of scheduled payments. We have a policy of requesting and reviewing periodic financial statements from commercial loan 
customers and employ a disciplined and formalized review of the existence of collateral and its value. The primary risk element with respect 
to each residential real estate loan and consumer loan is the timeliness of scheduled payments; loans 90 days or more past due are considered 
nonperforming. We have a reporting system that monitors past due loans and have adopted policies to pursue creditors’ rights in order to 
preserve our collateral position.

NOTE 3 – LOANS AND ALLOWANCE FOR CREDIT LOSSES (Continued)

We use a migration to loss methodology to determine historical loss rates for commercial loans given the comprehensive loan grading 
process employed by our bank for over two decades, while an open pool approach is best suited for retail loans given the smaller dollar size 
of the segments. A baseline loss rate is produced at each reporting date for each loan portfolio segment using bank-specific loan charge-off 
and recovery data over a defined historical look-back period. The look-back period represents the number of data periods that will be used to
calculate a baseline loss rate for each loan portfolio segment. We determined that the look-back period commencing on January 1, 2011 
through the reporting date was reasonable and appropriate for the calculation of historical loss rates for both December 31, 2024 and 2023.

Our historical loss rate is then applied to future loan balances at the instrument level based on remaining contractual life adjusted for 
amortization, prepayment and default to develop a baseline lifetime loss. Our prepayment speed assumptions are developed at the loan 
segment level based upon the consideration of all relevant data in which we believe will impact anticipated customer behavior including 
changes in interest rates, economic conditions, and underlying property valuations. For the commercial loan portfolio segments, we assumed 
a 2% prepayment speed as of both December 31, 2024 and 2023 as we deemed there to be no considerable changes from historical 
experience. For the retail 1-4 family mortgage and retail other consumer portfolios, we decreased the prepayment speed from 9.0% as of 
December 31, 2023 to 7.8% as of December 31, 2024. This decrease extended the average lives of the portfolios in which the loss rates were 
applied, resulting in an increase to the allowance of $1.3 million. This change in assumption was driven by higher long-term interest rates and 
the composition of the underlying portfolios.

During each reporting period, we also consider the need to adjust the historical loss rates as determined to reflect the extent to which we 
expect current conditions and reasonable and supportable economic forecasts to differ from the conditions that existed for the period over 
which the historical loss information was determined. These qualitative adjustments may increase or decrease our estimate of expected future 
credit losses. As of December 31, 2024 and 2023, we used a one-year reasonable and supportable economic forecast period, with a six-month 
straight-line reversion period for all loan segments. The economic forecasts used for our December 31, 2024 and 2023 allowance calculations 
reflected allowance balance reductions of $2.2 million and $2.0 million, respectively.

Individual loans exhibiting unique risk characteristics, which differentiate the loans from other loans within the loan segments and are 
evaluated for expected credit losses on an individual basis, totaled $7.4 million and $5.4 million as of December 31, 2024 and 2023, 
respectively. Individual allowance allocations totaled $2.2 million and $0.4 million as of December 31, 2024 and 2023, respectively.

Depreciation expense totaled $6.0 million in 2024, 2023 and 2022.

We enter into facility leases in the normal course of business. As of December 31, 2024, we were under lease contracts for eleven of our 
branch facilities. The leases have maturity dates ranging from November, 2025 through May, 2048, with a weighted average life of 8.8 years 
as of December 31, 2024. All of our leases have multiple three- to five-year extensions; however, these were not factored in the lease 
maturities and weighted average lease term as it is not reasonably certain we will exercise the options.

Leases are classified as either operating or finance leases at the lease commencement date, with all of our current leases determined to be 
operating leases. Lease expense for operating leases is recognized on a straight-line basis over the lease term. Right-of-use assets represent 
our right to use an underlying asset for the lease term, while lease liabilities represent our obligation to make lease payments arising from the 
lease. Right-of-use assets and lease liabilities are recognized at the lease commencement date at the estimated present value of lease payments 
over the lease term. We use our incremental borrowing rate, on a collateralized basis, at lease commencement to calculate the present value of

The right-of-use assets, included in premises and equipment, net on our Consolidated Balance Sheets, and the lease liabilities, included in
other liabilities on our Consolidated Balance Sheets, totaled $4.4 million and $3.7 million as of December 31, 2024, and December 31, 2023,

Mortgage servicing rights result from our mortgage loan origination activities. Late and ancillary fees, included as part of mortgage banking 
income and reported as noninterest income in the Consolidated Statements of Income, aggregated less than $0.1 million during 2024 and 
2023.

We determined that no valuation allowance was necessary as of December 31, 2024 or December 31, 2023. The estimated fair value of 
mortgage servicing rights was $21.0 million and $19.3 million as of December 31, 2024 and 2023, respectively. The fair value of mortgage 
servicing rights is estimated using a valuation model that calculates the present value of estimated future net servicing cash flows, taking into 
consideration expected mortgage loan prepayment rates, discount rates, servicing costs and other economic factors, which are determined 
based on current market conditions. As of December 31, 2024, fair value was determined using a discount rate of 10.50%, a weighted 
average constant prepayment rate of 7.81%, depending on the stratification of the specific right, and a weighted average delinquency rate of 
0.68%. As of December 31, 2023, fair value was determined using a discount rate of 11.00%, a weighted average constant prepayment rate of 
7.44%, depending on the stratification of the specific right, and a weighted average delinquency rate of 0.29%.

The weighted average amortization period was 8.7 years and 8.6 years as of December 31, 2024 and 2023, respectively.

related to such assets will not be realized. We determined that no valuation allowance was required at year-end 2024 or 2023. We had no 
unrecognized tax benefits at any time during 2024 or 2023 and do not anticipate any significant increase in unrecognized tax benefits during 
2025. Should the accrual of any interest or penalties relative to unrecognized tax benefits be necessary, it is our policy to record such accruals

NOTE 10 – STOCK-BASED COMPENSATION

Stock-based compensation plans are used to provide directors and employees with an increased incentive to contribute to our long-term 
performance and growth, to align the interests of directors and employees with the interests of our shareholders through the opportunity for 
increased stock ownership and to attract and retain directors and employees. Stock-based compensation, reported as noninterest expense in 
the Consolidated Statements of Income, totaled $3.3 million, $3.4 million and $3.4 million in 2024, 2023 and 2022, respectively. The Stock 
Incentive Plan of 2020 was approved by shareholders in May, 2020, and was effectively replaced with the Stock Incentive Plan of 2023 that 
was approved by shareholders in May, 2023.

Grants included on the following tables were made under the various Stock Incentive Plans as follows:

In addition, stock grants to directors as retainer payments during the years 2020 through 2022 were from the Stock Incentive Plan of 2020, 
while stock grants to directors as retainer payments during 2024 and 2023 were from the Stock Incentive Plan of 2023.

Under the Stock Incentive Plan of 2020 and the Stock Incentive Plan of 2023, incentive awards may include, but are not limited to, stock
options, restricted stock, stock appreciation rights and stock awards. Incentive awards that are stock options or stock appreciation rights are 
granted with an exercise price not less than the closing price of our common stock on the date of grant. Price, vesting and expiration date 
parameters are determined by Mercantile’s Compensation Committee on a grant-by-grant basis. No payments are required from employees 
for restricted stock awards. The restricted stock awards granted during the years 2021 through 2023 fully vest after three years and, in the 
case of performance-based restricted stock issued to executive officers in 2020 through 2023, are subject to the attainment of pre-determined 
performance goals. At year-end 2024, there were approximately 383,000 shares authorized for future incentive awards.

NOTE 12 – COMMITMENTS AND OFF-BALANCE-SHEET RISK 

We are a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of our 
customers. These financial instruments include commitments to extend credit and standby letters of credit. Loan commitments to extend 
credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Standby letters of 
credit are conditional commitments issued by our bank to guarantee the performance of a customer to a third party. Commitments generally 
have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to 
expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements.

These instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized, if any, in the balance sheet. Our 
maximum exposure to loan loss in the event of nonperformance by the other party to the financial instrument for commitments to extend 
credit and standby letters of credit is represented by the contractual notional amount of those instruments. We use the same credit policies in 
making commitments and conditional obligations as we do for on-balance sheet instruments. Collateral, such as accounts receivable, 
securities, inventory, and property and equipment, is generally obtained based on management’s credit assessment of the borrower.

We are required to consider expected credit losses associated with loan commitments over the contractual period in which we are exposed to 
credit risk on the underlying commitments unless the obligation is unconditionally cancellable by us. Any allowance for off-balance sheet 
credit exposures is reported as an other liability on our Consolidated Balance Sheets and is increased or decreased via other noninterest 
expense on our Consolidated Statements of Income. The calculation includes consideration of the likelihood that funding will occur and 
forecasted credit losses on commitments expected to be funded over their estimated lives. The allowance is calculated using the same 
aggregate reserve rates calculated for the funded portion of loans at the portfolio level applied to the amount of commitments expected to be 
funded.

For commercial lines of credit, retail lines of credit and credit card average outstanding balances, we determined allowance requirements by 
calculating the difference between the average percent outstanding of the funded commitments over the past several years to actual percent 
outstanding at period end and applying the respective expected loss allocation factors to the difference as this difference represents the 
average of unfunded commitments we expect to eventually be drawn upon. For commitments to make loans, we determine an allowance by 
applying the expected loss allocation factor to the amount expected to fund. The calculated allowance aggregated $1.0 million and $1.3 
million as of December 31, 2024 and 2023, respectively. We do not reserve for residential mortgage construction loans, as the loans are for 
one year or less and draws are governed by the receipt and satisfactory review of contractor and subcontractor sworn statements, lien waivers 
and title insurance company endorsements. Letters of credit are rarely drawn.

Commitments to make commercial loans generally reflect our binding obligations to existing and prospective customers to extend credit, 
including line of credit facilities secured by accounts receivable and inventory, and term loans secured by either real estate or equipment.

In most instances, commercial line of credit facilities have terms ranging from 12 to 24 months with floating rates tied to the Wall Street 
Journal Prime Rate or 30-Day SOFR. Commercial term loans secured by real estate are generally at a floating rates tied to the Wall Street 
Journal Prime Rate or 30-Day SOFR. Since the fourth quarter of 2020, a fixed rate option for commercial term loans secured by real estate is 
generally not offered for loans over $2.5 million; instead, customers are offered participation in our back-to-back interest rate swap program 
to achieve a desired fixed rate. For loans under $2.5 million, we offer a rate primarily equal to the commensurate cost of funds using FHLBI 
advance rates as a proxy and a credit spread as indicated by the credit rating we assign. Commercial term loans secured by real estate 
generally balloon within five years, with payments based on amortizations ranging from 10 to 25 years. Commercial term loans secured by 
non-real estate collateral are generally at a floating rate tied to the Wall Street Journal Prime Rate or 30-Day SOFR, or a fixed rate primarily 
equal to the commensurate cost of funds using FHLBI advance rates as a proxy and a credit spread as indicated by the credit rating we assign, 
and generally mature and fully amortize within three to seven years. Effective January 1, 2022, we replaced the 30-Day Libor Rate with 30-
Day SOFR for all new and renewing floating rate commercial loans and commitments. Commercial loans tied to the 30-Day Libor Rate 
outstanding on June 30, 2023 converted to an equivalent fallback SOFR Rate.

The following standby letters of credit are considered financial guarantees under current accounting guidance. These instruments are carried 
at fair value as an other liability on our Consolidated Balance Sheets. Standby letters of credit are generally cross collateralized with the 
borrowers’ other loans with us, and are included in our borrower collateral analyses.

We have a 401(k) benefit plan that covers substantially all of our employees. The percent of our matching contributions to the 401(k) benefit 
plan is determined annually by the Board of Directors. The matching contribution has been 5.00% since April 1, 2018. Matching
contributions, if made, are immediately vested. Our 2024, 2023 and 2022 matching 401(k) contributions charged to expense were

also have a non-qualified deferred compensation program in which selected officers may defer all or portions of salary and bonus payments. 
The deferred amounts, which totaled $1.3 million and $1.1 million as of December 31, 2024 and 2023, respectively, are categorized as other 
liabilities in the Consolidated Balance Sheets, and are paid interest at a rate equal to the Wall Street Journal Prime Rate. Interest expense was 
less than $0.1 million during 2024, 2023, and 2022.

The Mercantile Bank Corporation Employee Stock Purchase Plan of 2014 is a non-compensatory plan intended to encourage full- and part-
time employees of Mercantile and its subsidiaries to promote our best interests and to align employees’ interests with the interests of our 
shareholders by permitting employees to purchase shares of our common stock through regular payroll deductions. Shares are purchased on 
the last business day of each calendar quarter at a price equal to the consolidated closing bid price of our common stock reported on The 
Nasdaq Stock Market. A total of 250,000 shares of common stock may be issued under the existing plan; however, the number of shares may 
be adjusted to reflect any stock dividends and other changes in our capitalization. The number of shares issued totaled 1,194 and 1,410 in 
2024 and 2023, respectively. As of December 31, 2024, there were approximately 233,000 shares available under our current plan.

NOTE 14 – DERIVATIVES AND HEDGING ACTIVITIES

We are exposed to certain risks arising from both business operations and economic conditions. We principally manage the exposure to a 
wide variety of operational risks through core business activities. Economic risks, including interest rate, liquidity and credit risk, are 
primarily administered via the amount, sources and duration of assets and liabilities. Derivative financial instruments may also be used to 
assist in managing economic risks.

Derivatives not designated as hedges are not speculative and result from a service provided to certain commercial loan borrowers. We 
execute interest rate swaps with commercial banking customers desiring longer-term fixed rate loans, while simultaneously entering into 
interest rate swaps with correspondent banks to offset the impact of the interest rate swaps with the commercial banking customers. The net 
result is the desired floating rate loans and a minimization of the risk exposure of the interest rate swap transactions. These swap agreements 
are cross collateralized with the underlying loans.

As the interest rate swaps associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both 
the commercial banking customer interest rate swaps and the offsetting interest rate swaps with the correspondent banks are recognized 
directly to earnings. Fees paid to us by the correspondent banks are recognized as noninterest income on our Consolidated Statements of 
Income on the settlement date.

It is not practical to determine the fair value of FHLBI stock due to transferability restrictions; therefore, fair value is estimated at 
carrying amount.

Carrying amount is the estimated fair value for cash and cash equivalents, FHLBI stock, accrued interest receivable and payable, noninterest-
bearing checking accounts and securities sold under agreements to repurchase. Security fair values are based on market prices or dealer 
quotes, and if no such information is available, on the rate and term of the security and information about the issuer. Fair value for loans is 
based on an exit price model as required by ASU 2016-01, taking into account inputs such as discounted cash flows, probability of default 
and loss given default assumptions. Fair value for deposit accounts other than noninterest-bearing checking accounts is based on discounted 
cash flows using current market rates applied to the estimated life. The fair values of subordinated debentures, subordinated notes, and 
FHLBI advances are based on current rates for similar financing. The fair values of interest rate swaps are based on discounted cash flows 
using forecasted yield curves, along with insignificant unobservable inputs, such as borrower credit spreads. The fair value of other off-
balance sheet items is estimated to be nominal.

NOTE 16 – FAIR VALUE MEASUREMENTS

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market 
participants. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for 
the asset or liability, or in the absence of a principal market, the most advantageous market for the asset or liability. The price of the principal 
(or most advantageous) market used to measure the fair value of the asset or liability is not adjusted for transaction costs. An orderly 
transaction is a transaction that assumes exposure to the market for a period prior to the measurement date to allow for marketing activities 
that are usual and customary for transactions involving such assets and liabilities; it is not a forced transaction. Market participants are buyers 
and sellers in the principal market that are (i) independent, (ii) knowledgeable, (iii) able to transact and (iv) willing to transact.

We are required to use valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. The 
market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets and 
liabilities. The income approach uses valuation techniques to convert future amounts, such as cash flows or earnings, to a single present 
amount on a discounted basis. The cost approach is based on the amount that currently would be required to replace the service capacity of an 
asset (replacement cost). Valuation techniques should be consistently applied. Inputs to valuation techniques refer to the assumptions that 
market participants would use in pricing the asset or liability. Inputs may be observable, meaning those that reflect the assumptions market 
participants would use in pricing the asset or liability developed based on market data obtained from independent sources, or unobservable, 
meaning those that reflect our own estimates about the assumptions market participants would use in pricing the asset or liability based on the 
best information available in the circumstances. In that regard, we utilize a fair value hierarchy for valuation inputs that gives the highest 
priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value 
hierarchy is as follows:

Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that we have the ability to access as of the measurement 
date.

Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities in active markets; 
quoted prices for identical or similar assets or liabilities in markets that are not active; or other inputs that are observable or can be derived 
from or corroborated by observable market data by correlation or other means.

Level 3: Significant unobservable inputs that reflect our own estimates about the assumptions that market participants would use in pricing an 
asset or liability.

The following is a description of our valuation methodologies used to measure and disclose the fair values of our financial assets and 
liabilities on a recurring or nonrecurring basis:

Securities available for sale. Securities available for sale are recorded at fair value on a recurring basis. Fair value measurement is based on 
quoted prices, if available. If quoted prices are not available, fair values are measured using independent pricing models. Level 2 securities
include U.S. Government agency debt obligations, mortgage-backed securities issued or guaranteed by U.S. Government agencies, and 
municipal general obligation and revenue bonds. Level 3 securities include bonds issued by certain relatively small municipalities located 
within our markets that have very limited marketability due to their size and lack of ratings from a recognized rating service. We carry these 
bonds at historical cost, which we believe approximates fair value, unless our periodic financial analysis or other information that becomes 
known to us necessitates an impairment. There was no such impairment as of December 31, 2024 or 2023. We have no Level 1 securities 
available for sale.

NOTE 16 – FAIR VALUE MEASUREMENTS (Continued)

Derivatives. We measure fair value utilizing models that use primarily market observable inputs, such as forecasted yield curves. 
Insignificant unobservable inputs, such as borrower credit spreads, are also utilized.

Mortgage loans held for sale. Mortgage loans originated and intended for sale in the secondary market are carried at the lower of aggregate 
cost or market, as determined by outstanding commitments from investors, and are measured on a nonrecurring basis. Fair value is based on 
independent quoted market prices, where applicable, or the prices for other mortgage whole loans with similar characteristics. As of
December 31, 2024 and 2023, we determined the fair value of our mortgage loans held for sale to be $16.0 million and $19.0 million, 
respectively.

Loans. We do not record loans at fair value on a recurring basis. However, from time to time, we record nonrecurring fair value adjustments 
to collateral dependent loans to reflect partial write-downs or specific reserves that are based on the observable market price or current 
estimated value of the collateral. These loans are reported in the nonrecurring table below at initial recognition of significant borrower 
distress and on an ongoing basis until recovery or charge-off. The fair values of distressed loans are determined using either the sales 
comparison approach or income approach; respective unobservable inputs for the approaches consist of adjustments for differences between 
comparable sales and the utilization of appropriate capitalization rates.

Foreclosed assets. At time of foreclosure or repossession, foreclosed and repossessed assets are adjusted to fair value less costs to sell upon 
transfer of the loans to foreclosed and repossessed assets, establishing a new cost basis. We subsequently adjust estimated fair value of 
foreclosed assets on a nonrecurring basis to reflect write-downs based on revised fair value estimates. The fair values of parcels of other real 
estate owned are determined using either the sales comparison approach or income approach; respective unobservable inputs for the 
approaches consist of adjustments for differences between comparable sales and the utilization of appropriate capitalization rates.

The carrying values are based on the estimated value of the property or other assets. Fair value estimates of collateral on collateral dependent 
loans and foreclosed assets are review periodically. Our credit policies establish criteria for obtaining appraisals and determining internal 
value estimates. We may also adjust outside appraisals and internal evaluations based on identifiable trends within our markets, such as sales 
of similar properties or assets, listing prices and offers received. In addition, we may discount certain appraised and internal value estimates 
to address current distressed market conditions. For real estate dependent loans and foreclosed assets, we assign a discount factor range of 
25% to 50%, providing for a weighted average discount factor of 27.4%, for commercial-related properties, and a discount factor range of 
25% to 35%, providing for a weighted average discount factor of 26.0%, for residential-related properties. In a vast majority of cases, we 
assign a 10% discount factor for estimated selling costs.

Basic earnings per share is based on the weighted average number of common shares and participating securities outstanding during the 
period. Diluted earnings per share include the dilutive effect of additional potential common shares issuable under our stock-based 
compensation plans and are determined using the treasury stock method. Our unvested restricted shares, which contain non-forfeitable rights 
to dividends whether paid or accrued (i.e., participating securities), are included in the number of shares outstanding for both basic and 
diluted earnings per share calculations. In the event of a net loss, our unvested restricted shares are excluded from the calculation of both 
basic and diluted earnings per share. Stock options for approximately 5,000 shares of common stock were antidilutive and were not included 
in determining dilutive earnings per share in 2022.

Variable interest entities ("VIEs") are entities that either have a total equity investment that is insufficient to permit the entity to finance its 
activities without additional subordinated financial support or whose equity investors lack the characteristics of a controlling financial interest 
(i.e., ability to make significant decisions, through voting rights, right to receive the expected residual returns of the entity, and obligations to 
absorb the expected losses of the entity). Variable interest entities can be structured as corporations, trusts, partnerships, or other legal 
entities. We have relationships with certain variable interest entities related to the issuance of trust preferred securities and our tax credit 
investments.

We have five business trusts that are wholly-owned subsidiaries of Mercantile, four of which were assumed by Mercantile in conjunction 
with the Firstbank merger in 2014. A fair value discount of $15.0 million was recorded at the time of the merger, which is being amortized at 
$0.7 million annually over the following 21.5 years, 11 of which are remaining. Each of the trusts was solely formed to issue preferred 
securities that were sold in private sales. Through a small common stock investment, we own 100% of the voting equity shares of each trust. 
The proceeds from the preferred securities and common stock sales were used by the trusts to purchase Floating Rate Notes issued by 
Mercantile. The rates of interest, interest payment dates, call features and maturity dates of each Floating Rate Note are identical to its 
respective Preferred Securities. The net proceeds from the issuance of the Floating Rate Notes were used for a variety of purposes, including 
contributions to our bank as capital to provide support for asset growth and the funding of stock repurchase programs and certain 
acquisitions.

The assets, liabilities, operations and cash flows of each trust are solely related to the issuance, administration and repayment of the preferred 
securities held by third-party investors. We fully and unconditionally guarantee the obligations of each trust and are obligated to redeem the 
junior subordinated debentures upon maturity. We do not consolidate the trusts as we are not the primary beneficiary of these entities because 
our wholly-owned and indirect wholly-owned statutory subsidiaries do not have the power to direct the activities of the variable interest 
entity that most significantly impact the variable interest entity’s economic performance and do not have an obligation to absorb losses or the 
right to receive benefits that could potentially be significant to the variable interest entity. As such, we do not have a controlling financial 
interest in the variable interest entities.

The only significant assets of our trusts are the Floating Rate Notes, and the only significant liabilities of our trusts are the Preferred 
Securities. The Floating Rate Notes are categorized on our Consolidated Balance Sheets as subordinated debentures and the interest expense 
is recorded on our Consolidated Statements of Income under interest expense on other borrowings.

On January 26, 2016, we closed on a repurchase of trust preferred securities that were auctioned as part of a pooled collateralized debt 
obligation (“Fund”). The Fund owned $11.0 million of the $32.0 million in trust preferred securities that had been issued by Mercantile Bank 
Capital Trust I. The $11.0 million in trust preferred securities was retired upon the repurchase, resulting in a commensurate reduction in the 
related Floating Rate Junior Subordinate Note, leaving $21.0 million outstanding.

MCP makes equity investments as a limited liability member in affordable housing projects utilizing the Low-Income Housing Tax Credit 
(“LIHTC”) pursuant to Section 42 of the Internal Revenue Code. Our bank also invests in multi-investor funds, which in turn invest in 
projects similar to that of MCP. The purpose of these investments is to achieve a satisfactory return on capital and to support our bank’s 
community reinvestment initiatives. The activities of the limited liability entities include the identification, development, and operation of 
multi-family housing that is leased to qualifying residential tenants generally within our bank’s primary geographic region. MCP also makes 
equity investments via special purpose investment entities as a limited liability member in entities that receive Historic Tax Credits (“HTC”) 
pursuant to Section 47 of the Internal Revenue Code. The purpose of these investments is the rehabilitation of historic buildings with the tax 
credits provided to incent private investment in the historic cores of cities and towns.

The LIHTC and HTC investment entities are considered VIEs as MCP, or our bank, whomever is the holder of the equity investment at risk, 
does not have the ability to direct the activities that most significantly affect the performance of the entity through voting rights or similar 
rights. MCP, or our bank, could absorb losses that are significant to the underlying entities as it has a risk of loss for its capital contributions 
and funding commitments to each. The general partners, or managing members, are considered the primary beneficiaries as managerial 
functions give them the power to direct the activities that most significantly impact the entities’ economic performances, and the managing 
members are exposed to all losses beyond MCP’s, or our bank’s, initial capital contributions and funding commitments.

Equity investments as a limited liability member in LIHTC and HTC investment entities, reported as other assets in the Consolidated Balance 
Sheets, totaled $38.9 million and $25.7 million as of December 31, 2024 and 2023, respectively. Unfunded capital commitments, reported as 
other liabilities in the Consolidated Financial Statements, totaled $34.4 million and $21.1 million as of December 31, 2024 and 2023,

NOTE 19 – SUBORDINATED NOTES

On December 15, 2021, we entered into Subordinated Note Purchase Agreements with certain institutional accredited investors pursuant to 
which we issued and sold $75.0 million in aggregate principal amount of 3.25% fixed-to-floating rate subordinated notes (“Notes”). The 
Notes have a stated maturity of January 30, 2032, and are redeemable by us at our option, in whole or in part, on or after January 30, 2027 on 
any interest payment date at a redemption of price of 100% of the principal amount of the Notes being redeemed. The Notes are not subject to 
redemption at the option of the holder. The Notes will bear interest at a fixed rate of 3.25% per year until January 29, 2027. Commencing on 
January 30, 2027 and through the stated maturity date of January 30, 2032, the interest rate will reset quarterly at a variable rate equal to the 
then-current Three-Month Term SOFR plus 212 basis points. On December 15, 2021, we injected $70.0 million of the issuance proceeds into 
our bank as an increase to equity capital.

On January 14, 2022, we issued an additional $15.0 million of Notes to certain institutional accredited investors, reflecting an expansion of 
the $75.0 million issuance completed on December 15, 2021. The additional $15.0 million issuance was completed on the same terms as the 
prior offering and under the existing indenture. On January 14, 2022, we injected $15.0 million of the issuance proceeds into our bank as an 
increase to equity capital.

Our unamortized debt issuance costs were $0.7 million and $1.0 million as of December 31, 2024 and 2023, respectively.

NOTE 20 - REGULATORY MATTERS

We are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and prompt 
corrective action regulations involve quantitative measures of assets, liabilities, and certain off-balance sheet items calculated under 
regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators about components, 
risk weightings, and other factors, and the regulators can lower classifications in certain cases. Failure to meet various capital requirements 
can initiate regulatory action that could have a direct material effect on the financial statements.

The prompt corrective action regulations provide five classifications, including well capitalized, adequately capitalized, undercapitalized, 
significantly undercapitalized, and critically undercapitalized, although these terms are not used to represent overall financial condition. If an 
institution is not well capitalized, regulatory approval is required to accept brokered deposits. Subject to limited exceptions, no institution 
may make a capital distribution if, after making the distribution, it would be undercapitalized. If an institution is undercapitalized, it is subject 
to close monitoring by its principal federal regulator, its asset growth and expansion are restricted, and plans for capital restoration are 
required. In addition, further specific types of restrictions may be imposed on the institution at the discretion of the federal regulator. At year-
end 2024 and 2023, our bank was in the well capitalized category under the regulatory framework for prompt corrective action. There are no 
conditions or events since December 31, 2024 that we believe have changed our bank’s categorization.

NOTE 20 – REGULATORY MATTERS (Continued)

Under the final BASEL III capital rules that became effective on January 1, 2015, there is a requirement for a common equity Tier 1 capital 
conservation buffer of 2.5% of risk-weighted assets which is in addition to the other minimum risk-based capital standards in the rule. 
Institutions that do not meet this required capital buffer will become subject to progressively more stringent limitations on the percentage of 
earnings that can be paid out in cash dividends or used for stock repurchases and on the payment of discretionary bonuses to senior executive 
management. The capital buffer requirement was phased in over three years beginning in 2016. The capital buffer requirement raised the 
minimum required common equity Tier 1 capital ratio to 7.0%, the Tier 1 capital ratio to 8.5% and the total capital ratio to 10.5% on a fully 
phased-in basis on January 1, 2019. We believe that, as of December 31, 2024, our bank meets all capital adequacy requirements under the 
BASEL III capital rules on a fully phased-in basis.

Federal and state banking laws and regulations place certain restrictions on the amount of dividends our bank can transfer to Mercantile and 
on the capital levels that must be maintained. At year-end 2024, under the most restrictive of these regulations, our bank could distribute 
$130 million to Mercantile as dividends without prior regulatory approval. Our and our bank’s ability to pay cash and stock dividends is 
subject to limitations under various laws and regulations and to prudent and sound banking practices. On January 11, 2024, our Board of 
Directors declared a cash dividend on our common stock in the amount of $0.35 per share that was paid on March 13, 2024 to shareholders of 
record as of March 1, 2024. On April 11, 2024, our Board of Directors declared a cash dividend on our common stock in the amount of 
$0.35 per share that was paid on June 19, 2024 to shareholders of record as of June 7, 2024. On July 11, 2024, our Board of Directors 
declared a cash dividend on our common stock in the amount of $0.36 per share that was paid on September 18, 2024 to shareholders of 
record as of September 6, 2024. On October 10, 2024, our Board of Directors declared a cash dividend on our common stock in the amount 
of $0.36 per share that was paid on December 18, 2024 to shareholders of record as of December 6, 2024.

As of December 31, 2024, we had the ability to repurchase up to $6.8 million in common stock shares from time to time in open market 
transactions at prevailing market prices or by other means in accordance with applicable regulations as part of a $20.0 million common stock 
repurchase program announced in May 2021. No shares were repurchased during 2024 or 2023. Historically, stock repurchases have been 
funded from cash dividends paid to us from our bank. Additional repurchases may be made in future periods under the authorized plan or a 
new plan, which would also likely be funded from cash dividends paid to us from our bank. The actual timing, number and value of shares 
repurchased will be determined by us in our discretion and will depend on a number of factors, including the stock price, capital position, 
financial performance, general market and economic conditions, alternative uses of capital and applicable legal requirements.

Our consolidated capital levels as of December 31, 2024 and 2023 include $48.3 million and $47.6 million, respectively, of trust preferred 
securities. Under applicable Federal Reserve guidelines, the trust preferred securities constitute a restricted core capital element. The 
guidelines provide that the aggregate amount of restricted core capital elements that may be included in Tier 1 capital must not exceed 25% 
of the sum of all core capital elements, including restricted core capital elements, net of goodwill less any associated deferred tax liability. 
Our ability to include the trust preferred securities in Tier 1 capital in accordance with the guidelines is not affected by the provision of the 
Dodd-Frank Act generally restricting such treatment, because (i) the trust preferred securities were issued before May 19, 2010, and (ii) our 
total consolidated assets as of December 31, 2009 were less than $15.0 billion. At December 31, 2024 and 2023, all $48.3 million and 
$47.6 million, respectively, of the trust preferred securities were included as Tier 1 capital of Mercantile.
