PRELIMINARY PROSPECTUS AND PROXY STATEMENT
DATED JANUARY 30, 2018, SUBJECT TO COMPLETION

MERGER PROPOSED – YOUR VOTE IS VERY IMPORTANT

The board of directors of TCSB Bancorp, Inc. (“TCSB”) is furnishing this prospectus and proxy statement and the accompanying form of proxy to the shareholders of TCSB to solicit proxies to vote at a special meeting of TCSB’s shareholders to be held on [•], 2018, at [•], [•], Michigan [•] at [•] local time and at any adjournments of the special meeting. At the special meeting, the shareholders of TCSB will consider and vote upon a proposal to approve an agreement and plan of merger (“merger agreement”) with Independent Bank Corporation (“IBCP”), under which TCSB will be merged with and into IBCP (the “merger”). This prospectus and proxy statement, when delivered to shareholders of TCSB, is also a prospectus of IBCP relating to an offering of IBCP common stock. This offering is made only to holders of TCSB common stock.

Completion of the merger is subject to regulatory approval, approval of the merger agreement by TCSB shareholders, and other customary closing conditions. If the merger agreement is approved and the merger is completed, each outstanding share of TCSB common stock that you hold will be converted into the right to receive 1.1166 shares (the “Exchange Ratio”) of IBCP common stock plus cash in lieu of any fractional share (together, the “Merger Consideration”). IBCP’s common stock is listed on The NASDAQ Global Select Market under the trading symbol “IBCP.” On December 4, 2017, the date of execution of the merger agreement, the closing price of a share of IBCP common stock was $22.55. On [•], 2018, the closing price of a share of IBCP common stock was $[•]. TCSB’s common stock is not traded on any exchange.

There are three circumstances under which the Exchange Ratio may change. First, if TCSB’s consolidated shareholders’ equity, as calculated in accordance with the merger agreement, is less than $34.5 million as of the Final Statement Date (as such term is defined in the merger agreement), the Exchange Ratio will be reduced so that the aggregate value of the Merger Consideration is reduced by the amount of such shortfall in TCSB’s consolidated shareholders’ equity. There is no cap on this potential decrease to the Exchange Ratio. As of December 31, 2017, TCSB’s consolidated shareholders’ equity, as calculated in accordance with the merger agreement, was approximately $35.0 million. Although there can be no guarantee, as of the date of this prospectus and proxy statement, TCSB and IBCP do not anticipate there will be any adjustment to the Exchange Ratio as a result of this provision of the merger agreement.

The second circumstance under which the Exchange Ratio may change would result in a potential increase to the Exchange Ratio. This potential increase to the Exchange Ratio would occur if the average price of IBCP common stock during a period prior to closing, as calculated in accordance with the merger agreement, is less than $19.07 and certain other conditions are met. There is no cap on this potential increase to the Exchange Ratio. IBCP has the right to decline to adjust the Exchange Ratio pursuant to this provision of the merger agreement, which could lead to a termination of the merger agreement by TCSB. As of [•], 2018, the closing price of a share of IBCP common stock was $[•]. Although there can be no guarantee, as of the date of this prospectus and proxy statement, TCSB and IBCP do not anticipate there will be any adjustment to the Exchange Ratio as a result of this provision of the merger agreement.

Finally, the Exchange Ratio will be proportionately adjusted if there is a recapitalization or similar event with respect to the outstanding shares of IBCP common stock or TCSB common stock prior to the merger, which is not currently expected. There is no cap on this potential adjustment to the Exchange Ratio. Please see “The Merger Agreement - What TCSB Shareholders will Receive in the Merger” starting on page 41 below for more details regarding each of these potential adjustments to the Exchange Ratio.

Assuming the Exchange Ratio does not get adjusted, and based on a total of [•] shares of TCSB common stock outstanding as of the record date, the aggregate Merger Consideration will consist of approximately 2.7 million shares of IBCP common stock. Based on the closing price of IBCP common stock on [•], 2018 of $[•], the value of such aggregate Merger Consideration is approximately $[•].

TCSB’s board of directors has unanimously determined that the merger is in substantial compliance with all applicable laws and is fair to and in the best interests of TCSB and TCSB’s shareholders, adopted the merger agreement and authorized the merger and the other transactions contemplated by the merger agreement, and unanimously recommends that TCSB shareholders vote “FOR” approval of the merger agreement. In the opinion of D.A. Davidson & Co., the Exchange Ratio is fair, from a financial point of view, to TCSB.

Your vote is important. Approval of the merger agreement requires the affirmative vote of a majority of the outstanding shares of TCSB common stock as of the record date for the special meeting. Please submit your proxy as soon as possible, regardless of whether or not you expect to attend the meeting in person.

Please read this prospectus and proxy statement carefully because it contains important information about the merger and the merger agreement. Read carefully the risk factors beginning on page 12. You can also obtain additional information about IBCP from documents that it has filed with the Securities and Exchange Commission (“SEC”) at www.sec.gov.

The shares of IBCP common stock to be issued in the merger are not deposits or savings accounts or other obligations of any bank or savings association, and are not insured by the Federal Deposit Insurance Corporation or any other governmental agency. IBCP common stock is subject to investment risks, including possible loss of value.

Neither the SEC nor any state securities commission has approved or disapproved of these securities or determined if this prospectus and proxy statement is truthful or complete. Any representation to the contrary is a criminal offense.

This prospectus and proxy statement is dated [•], 2018,
and it is first being mailed to TCSB shareholders on or about [•], 2018.

TABLE OF CONTENTS

FORWARD-LOOKING STATEMENTS

This prospectus and proxy statement 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 IBCP and TCSB. Words such as “anticipates,” “believes,” “estimates,” “expects,” “forecasts,” “intends,” “is likely,” “judgment,” “opinion,” “plans,” “predicts,” “probable,” “projects,” “should,” “trend,” “will,” “strategy” and variations of such words and similar expressions are intended to identify such forward-looking statements. Such statements are based upon current beliefs and expectations and involve substantial risks and uncertainties which could cause actual results to differ materially from those expressed or implied by such forward-looking statements. These statements include, among others, statements related to future levels of loan charge-offs, future levels of provisions for loan losses, real estate valuation, future levels of nonperforming assets, the rate of asset dispositions, future capital levels, future changes in regulatory requirements, future dividends, future growth and funding sources, future liquidity levels, future profitability levels, future deposit insurance premiums, the effects on earnings of future changes in interest rates, the future level of other revenue sources, future economic trends and conditions, future initiatives to expand market share, expected performance and cash flows from acquired loans, future effects of new or changed accounting standards, future opportunities for acquisitions, opportunities to increase top line revenues, the ability to grow core franchise, future cost savings and the ability to maintain adequate liquidity and capital based on the requirements adopted by the Basel Committee on Banking Supervision and U.S. regulators. All statements referencing future time periods are forward-looking.

Management’s determination of the provision and allowance for loan losses; the carrying value of acquired loans, goodwill and mortgage servicing rights; the fair value of investment securities (including whether any impairment on any investment security is temporary or other-than-temporary and the amount of any impairment); and management’s assumptions concerning pension and other postretirement benefit plans involve judgments that are inherently forward-looking. There can be no assurance that future loan losses will be limited to the amounts estimated. All of the information concerning interest rate sensitivity is forward-looking. The future effect of changes in the financial and credit markets and the national and regional economies on the banking industry, generally, and on IBCP and TCSB, specifically, are also inherently uncertain. These statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions (“risk 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. IBCP and TCSB undertake no obligation to update, amend, or clarify forward-looking statements, whether as a result of new information, future events, or otherwise.

Risk factors relating to IBCP’s business in general include, without limitation:

Risk factors relating both to the merger and the integration of TCSB into IBCP after the effective time of the merger include, without limitation:

Important factors that could cause actual results to differ materially from expectations include, but are not limited to, the risk factors described under “Risk Factors” beginning on page 12 of this prospectus and proxy statement. These and other factors are representative of the risk factors that may emerge and could cause a difference between an ultimate outcome and a preceding forward-looking statement.

QUESTIONS AND ANSWERS ABOUT THE MERGER

Additionally, you are being asked to vote to approve the Adjournment Proposal.

If you hold shares in book-entry form, you do not need to take any action at this time to exchange your shares. After the effective time of the merger, you will receive instructions on how to exchange your shares.

The presence, in person or by proxy, of the holders of shares representing a majority of the votes entitled to be cast by the TCSB shareholders at the special meeting is necessary to constitute a quorum. Abstentions will be counted as present and entitled to vote for purposes of determining a quorum.

The affirmative vote of the holders of a majority of the shares of TCSB common stock outstanding as of the record date for the special meeting is required to approve the merger agreement. Because the required vote of TCSB shareholders on the merger agreement is based upon the number of outstanding shares of TCSB common stock entitled to vote rather than upon the number of shares actually voted, a failure to vote and abstentions will have the same practical effect as a vote against approval of the merger agreement.

The affirmative vote of the holders of a majority of votes cast at the special meeting is necessary to approve the Adjournment Proposal. A failure to vote and abstentions will have no effect on this proposal.

If you properly complete and sign your proxy but do not indicate how your shares of TCSB common stock should be voted on a proposal, the shares of TCSB common stock represented by your proxy will be voted “FOR” approval of the merger agreement and “FOR” approval of the Adjournment Proposal.

No approval by IBCP shareholders is required.

Ann Bollinger, stating that you would like to revoke your proxy. This notice must be received before the special meeting date. Second, you may complete and submit a new proxy, dated at a date later than your most recent proxy. Third, you may attend the special meeting and vote in person. Your attendance at the special meeting will not, however, by itself revoke your proxy. If you have instructed a broker to vote your shares, you must follow the directions you receive from your broker to change your vote. Your last vote will be the vote that is counted.

Each party also has the right to terminate the merger agreement if a governmental entity prohibits the merger, if the merger does not occur on or before September 4, 2018, or if the TCSB shareholder meeting is finally adjourned without the TCSB shareholders having approved the merger, provided that, in each case, the failure of the party seeking to terminate the merger agreement to perform its obligations under the merger agreement has not been a substantial cause of, or a substantial factor that resulted in, any of such events having occurred.

In addition, each party has certain other rights to terminate the merger agreement in limited circumstances. Please see “Termination of the Merger Agreement” beginning on page 55 below for more information.

SUMMARY

This summary highlights selected information from this prospectus and proxy statement. It may not contain all of the information that is important to you. For a more complete understanding of the merger between IBCP and TCSB, we urge you to carefully read and consider this entire document, the merger agreement (attached as Appendix A to this prospectus and proxy statement and incorporated herein by reference).

The Companies

IBCP

Independent Bank Corporation
4200 East Beltline
Grand Rapids, Michigan 49525
(616) 527-5820

Independent Bank Corporation (NASDAQ: IBCP) is a Michigan-based bank holding company. Founded as First National Bank of Ionia in 1864, IBCP operates a branch network across Michigan’s Lower Peninsula through one state-chartered bank subsidiary. This subsidiary (Independent Bank) provides a full range of financial services, including commercial banking, mortgage lending, investments and insurance. IBCP is committed to providing exceptional personal service and value to its customers, stockholders and the communities it serves.

As of September 30, 2017, IBCP had total assets of $2.8 billion, total loans (including loans held for sale) of $2.0 billion, total deposits of $2.3 billion, and total shareholders’ equity of $267.7 million. As discussed under “ Recent Developments” on page 84 below, as a result of the Tax Cuts and Jobs Act enacted in December 2017, IBCP was required to revalue its net deferred tax assets. This revaluation resulted in an increase in income tax expense of $6.0 million, which was recorded in the fourth quarter of 2017.

TCSB

TCSB Bancorp, Inc.
333 West Grandview Parkway
Traverse City, Michigan 49684
(231) 995-5500

TCSB Bancorp, Inc. is a Michigan-based bank holding company. Founded in 2000, TCSB is the parent company of Traverse City State Bank and provides a full array of banking services through five full-service branches in the Traverse City area.

As of September 30, 2017, TCSB had total assets of $348.9 million, total loans of $280.3 million, total deposits of $291.6 million, and total shareholders’ equity of $33.4 million. As a result of the Tax Cuts and Jobs Act enacted in December 2017, TCSB recorded a tax benefit of approximately $426,000, which was recorded in the fourth quarter of 2017.

Summary of Certain Aspects of the Merger

Structure of the Merger; Bank Consolidation (page 41)

If the merger is completed, TCSB will be merged with and into IBCP, with IBCP as the surviving corporation. Following completion of the merger, IBCP intends to consolidate Traverse City State Bank with and into Independent Bank, with Independent Bank as the surviving bank.

What TCSB Shareholders will Receive in the Merger (page 41)

If the merger is completed as planned, each share of TCSB common stock will be converted into the right to receive the Merger Consideration, consisting of 1.1166 shares (the “Exchange Ratio”) of IBCP common stock, plus cash in lieu of any fractional share of IBCP common stock. The Merger Consideration is subject to the following adjustments:

“Company Consolidated Shareholders’ Equity” means TCSB’s total consolidated shareholders’ equity as of the Final Statement Date computed in accordance with U.S. generally accepted accounting principles (“GAAP”), consistently applied and excluding the net accumulated other comprehensive income/(loss) related to unrealized investment securities gains/(losses), and subject to additional adjustments as set forth in Section 5.26.1 of the merger agreement.

“Final Statement Date” means the last day of the calendar month preceding the date on which both TCSB’s shareholders have approved the merger and all regulatory approvals required by law to consummate the merger have been obtained (statutory waiting periods need not have expired), or such other date as agreed upon by IBCP and TCSB.

“Stock Purchase Value” is equal to the Exchange Ratio in effect at the time of the adjustment multiplied by the total number of shares of TCSB common stock outstanding as of the effective time of the merger multiplied by the Final Purchaser Price (as defined below and in the merger agreement).

The “Final Purchaser Price” means the 15-day volume weighted average price of IBCP common stock ending on the sixth business day prior to the closing date for the merger in transactions reported on The Nasdaq Global Select Market.

The “Initial Index Price” means the closing price of the KBW Regional Banking Index (KRX), a sector index maintained by the Nasdaq Stock Market on December 1, 2017.

The “Final Index Price” means the closing price of the KBW Regional Banking Index (KRX) on the sixth business day prior to the closing date for the merger.

IBCP will not issue fractional shares of IBCP common stock in the merger. A TCSB shareholder who would otherwise be entitled to receive a fraction of a share of IBCP common stock in the merger will instead receive an amount of cash determined by multiplying that fraction by the Final Purchaser Price.

If, prior to the effective time of the merger, Traverse City State Bank receives a net recovery on a particular loan that is in default, TCSB is entitled to make a special cash dividend to its shareholders, in an amount specified by the merger agreement. See “The Merger Agreement – Potential Special Dividend” below for more information.

Recommendation of TCSB’s Board of Directors (page 22)

TCSB’s board of directors has unanimously determined that the merger is in substantial compliance with all applicable laws and is fair to and in the best interests of TCSB and TCSB’s shareholders, adopted the merger agreement and authorized the merger and the other transactions contemplated by the merger agreement, and unanimously recommends that TCSB shareholders vote “FOR” approval of the merger agreement and “FOR” approval of the Adjournment Proposal.

Vote Required for Approval; Voting Agreement (page 23)

The affirmative vote of the holders of a majority of the shares of TCSB common stock outstanding as of the record date for the special meeting is required to approve the merger agreement. The affirmative vote of the holders of a majority of votes cast at the special meeting is necessary to approve the Adjournment Proposal. No approval by IBCP shareholders is required.

As of the record date, TCSB’s directors, executive officers and their affiliates beneficially owned [•] shares of TCSB common stock, or approximately [•]% of the shares of TCSB common stock entitled to vote at the special meeting. Each of TCSB’s directors has entered into a voting agreement pursuant to which he or she has agreed, subject to certain exceptions, to vote his or her shares, and to use reasonable efforts to cause all shares owned by such director jointly with another person or by such director’s spouse or over which the director has voting influence or control to be voted, in favor of approval of the merger agreement.

Fairness Opinion of TCSB’s Financial Advisor (page 30)

In connection with the merger, the board of directors of TCSB received a written opinion, dated December 4, 2017, from TCSB’s financial advisor, D.A. Davidson & Co. (“DADCO”), to the effect that, as of the date of the opinion and based on and subject to the various considerations described in the opinion, the Exchange Ratio is fair, from a financial point of view, to TCSB. The full text of DADCO’s written opinion, which sets forth, among other things, the assumptions made, procedures followed, matters considered, and limitations on the review undertaken by DADCO in rendering its opinion, is attached to this document as Appendix B. We encourage you to read the entire opinion carefully. The opinion of DADCO is directed to the board of directors of TCSB and does not constitute a recommendation to any TCSB shareholder as to how to vote at the special meeting or any other matter relating to the merger agreement or the merger.

Conditions to Complete the Merger (page 52)

The completion of the merger depends on a number of conditions being satisfied or, where permissible, waived. These conditions include, among others, receipt of regulatory approval, approval of TCSB shareholders, and other customary closing conditions. We cannot be certain when, or if, the conditions to the merger will be satisfied or waived, or that the merger will be completed.

Regulatory Approvals for the Merger (page 52)

Completion of the merger is subject to the approval of the Federal Reserve Board and the Michigan Department of Insurance and Financial Services. The applications to obtain such approval have been filed with these regulatory agencies as of the date of this prospectus and proxy statement. Although IBCP does not know of any reason why it will not obtain these regulatory approvals in a timely manner, it cannot be certain when or if it will obtain them.

Termination of the Merger Agreement (page 55) and Termination Fee (page 56)

The merger agreement can be terminated at any time prior to completion of the merger by mutual consent of the boards of directors of IBCP and TCSB. Also, either party can terminate the merger agreement in various circumstances. In some circumstances, TCSB is required to pay IBCP a termination fee of $2,529,658.

No Dissenters’ Rights in the Merger (page 39)

Dissenters’ rights are rights that, if available under law, enable shareholders to dissent from an extraordinary transaction, such as a merger, and to demand that the corporation pay the fair value for their shares as determined by a court in a judicial proceeding instead of receiving the consideration offered to shareholders in connection with the extraordinary transaction. Dissenters’ rights are not available in all circumstances, and exceptions to these rights are provided in the Michigan Business Corporation Act (“MBCA”). Under the MBCA and TCSB’s articles of incorporation, holders of TCSB common stock will not have dissenters’ rights in connection with the merger.

Material United States Federal Income Tax Consequences (page 39)

IBCP and TCSB expect the merger to qualify as a “reorganization” for U.S. federal income tax purposes. If the merger qualifies as a reorganization, then, in general, holders of TCSB common stock who exchange their TCSB stock for IBCP stock will not recognize any gain or loss for U.S. federal income tax purposes upon that exchange.

You are urged to consult your own tax advisor regarding the particular consequences to you of the merger.

RISK FACTORS

In addition to the matters addressed in this prospectus and proxy statement, including the information under the heading “Forward-Looking Statements,” you should carefully consider the following risk factors in deciding how to vote on the merger agreement.

Risks Related to IBCP’s Business

Investing in IBCP’s common stock involves risks, including (among others) the following factors:

General political, economic or industry conditions, either domestically or internationally, may be less favorable than expected.

Local, domestic, and international economic, political and industry-specific conditions affect the financial services industry, directly and indirectly. Conditions such as or related to inflation, recession, unemployment, volatile interest rates, international conflicts and other factors outside of IBCP’s control, such as real estate values, energy costs, fuel prices, state and local municipal budget deficits, and government spending and the U.S. national debt, may, directly and indirectly, adversely affect IBCP. As has been the case with the impact of recent economic conditions, economic downturns could result in the delinquency of outstanding loans, which could have a material adverse impact on IBCP’s earnings.

Governmental monetary and fiscal policies may adversely affect the financial services industry and therefore impact IBCP’s financial condition and results of operations.

Monetary and fiscal policies of various governmental and regulatory agencies, particularly the Federal Reserve, affect the financial services industry, directly and indirectly. The Federal Reserve regulates the supply of money and credit in the U.S., and its monetary and fiscal policies determine in a large part IBCP’s cost of funds for lending and investing and the return that can be earned on such loans and investments. Changes in such policies, including changes in interest rates, will influence the origination of loans, the value of investments, the generation of deposits and the rates received on loans and investment securities and paid on deposits. Changes in monetary and fiscal policies are beyond IBCP’s control and difficult to predict. IBCP’s financial condition and results of operations could be materially adversely impacted by changes in governmental monetary and fiscal policies.

Volatility and disruptions in global capital and credit markets may adversely impact IBCP’s business, financial condition and results of operations.

Even though IBCP operates in a distinct geographic region in the U.S., it is impacted by global capital and credit markets, which are sometimes subject to periods of extreme volatility and disruption. Disruptions, uncertainty or volatility in the capital and credit markets may limit IBCP’s ability to access capital and manage liquidity, which may adversely affect IBCP’s business, financial condition and results of operations. Further, IBCP’s customers may be adversely impacted by such conditions, which could have a negative impact on IBCP’s business, financial condition and results of operations.

The soundness of other financial institutions could adversely affect IBCP.

IBCP’s 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 and other relationships. IBCP has exposure to many different industries and counterparties, and it routinely executes 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, and may further lead, to market-wide liquidity problems and could lead to losses or defaults by IBCP or by other institutions. Many of these transactions could expose IBCP to credit risk in the event of default by a counterparty. In addition, IBCP’s credit risk may be impacted when the collateral held by it cannot be realized upon or is liquidated at prices not sufficient to recover the full amount of the financial instrument exposure due to it. There is no assurance that any such losses would not adversely affect IBCP and possibly be material in nature.

Changes in regulation or oversight may have a material adverse impact on IBCP’s operations.

IBCP is subject to extensive regulation, supervision and examination by the Federal Reserve Board, the FDIC, the Michigan Department of Insurance and Financial Services, the SEC and other regulatory bodies. Such regulation and supervision governs the activities in which IBCP may engage. Regulatory authorities have extensive discretion

in their supervisory and enforcement activities, including the imposition of restrictions on IBCP’s operations, investigations and limitations related to IBCP’s securities, the classification of its assets and determination of the level of its allowance for loan losses. Any change in such regulation and oversight, whether in the form of regulatory policy, regulations, legislation or supervisory action, may have a material adverse impact on IBCP’s business, financial condition or results of operations.

In particular, Congress and other regulators have increased their focus on the regulation of the financial services industry in recent years. While recent changes in the executive branch may mitigate this impact, the effects on IBCP of recent legislation and regulatory actions cannot reliably be fully determined at this time. Moreover, as some of the legislation and regulatory actions previously implemented in response to the recent financial crisis expire, the impact of the conclusion of these programs on the financial sector and on the economic recovery is unknown. Any delay in the economic recovery or a worsening of current financial market conditions could adversely affect IBCP. IBCP can neither predict when or whether future regulatory or legislative reforms will be enacted nor what their contents will be. The impact of any future legislation or regulatory actions on IBCP’s businesses or operations cannot be determined at this time, and such impact may adversely affect IBCP.

IBCP has credit risk inherent in its loan portfolios, and its allowance for loan losses may not be sufficient to cover actual loan losses.

IBCP’s loan customers may not repay their loans according to their respective terms, and the collateral securing the payment of these loans may be insufficient to cover any losses IBCP may incur. IBCP makes various assumptions and judgments about the collectability of its loan portfolio, including the creditworthiness of its borrowers and the value of the real estate and other assets serving as collateral for the repayment of many of its loans. Non-performing loans amounted to $8.4 million and $13.4 million at September 30, 2017 and December 31, 2016, respectively. IBCP’s allowance for loan losses coverage ratio of non-performing loans was 255.39% and 151.41% at September 30, 2017 and December 31, 2016, respectively. In determining the size of the allowance for loan losses, IBCP relies on its experience and its evaluation of current economic conditions. If IBCP’s assumptions or judgments prove to be incorrect, its current allowance for loan losses may not be sufficient to cover certain loan losses inherent in its loan portfolio, and adjustments may be necessary to account for different economic conditions or adverse developments in its loan portfolio. Material additions to its allowance for loan losses would adversely impact its operating results.

In addition, federal and state regulators periodically review IBCP’s allowance for loan losses and may require IBCP to increase its provision for loan losses or recognize additional loan charge-offs, notwithstanding any internal analysis that has been performed. Any increase in IBCP’s allowance for loan losses or loan charge-offs required by these regulatory agencies could have a material adverse effect on its results of operations and financial condition.

IBCP has credit risk in its securities portfolio.

IBCP maintains diversified securities portfolios, which include obligations of the U.S. Treasury and government-sponsored agencies as well as securities issued by states and political subdivisions, mortgage-backed securities, corporate securities and asset-backed securities. IBCP seeks to limit credit losses in its securities portfolios by principally purchasing highly rated securities (generally rated “AA” or higher by a major debt rating agency) and by conducting due diligence on the issuer. However, gross unrealized losses on securities available for sale in its portfolio totaled approximately $1.8 million as of September 30, 2017 (compared to approximately $7.6 million as of December 31, 2016). IBCP believes these unrealized losses are temporary in nature and are expected to be recovered within a reasonable time period as it believes it has the ability to hold the securities to maturity or until such time as the unrealized losses reverse. However, IBCP evaluates securities available for sale for other than temporary impairment (OTTI) at least quarterly and more frequently when economic or market concerns warrant such evaluation. Those evaluations may result in OTTI charges to its earnings. In addition to these impairment charges, IBCP may, in the future, experience additional losses in its securities portfolio which may result in charges that could materially adversely affect its results of operations.

IBCP has agreed to indemnify the purchaser of Mepco’s business against certain losses it may incur as a result of its purchase of the business.

In connection with IBCP’s sale of substantially all of the assets of its Mepco subsidiary in May of 2017, it agreed to contractually indemnify the purchaser from certain losses the purchaser may incur, including as a result of its failure to collect certain receivables it purchased as part of the business as well as breaches of representations and

warranties IBCP made in the sale agreement, subject to various limitations. IBCP has not accrued any liability related to this sale in its financial statements because it believes the likelihood of having to pay any amount as a result of these indemnification obligations is remote. However, if the purchaser is unable to collect the receivables it purchased from Mepco or otherwise encounters difficulties in operating the business, it is possible it could make one or more claims against IBCP pursuant to the sale agreement. In that event, IBCP may incur expenses in defending any such claims and/or amounts paid to such purchaser to resolve such claims. As of September 30, 2017, the balance of these receivables had declined to $22.5 million, and to date the purchaser has made no claims for indemnification.

IBCP’s mortgage-banking revenues are susceptible to substantial variations, due in part to factors it does not control, such as market interest rates.

A portion of IBCP’s revenues are derived from net gains on mortgage loans. These net gains primarily depend on the volume of loans IBCP sells, which in turn depends on its ability to originate real estate mortgage loans and the demand for fixed-rate obligations and other loans that are outside of its established interest-rate risk parameters. Net gains on mortgage loans are also dependent upon economic and competitive factors as well as IBCP’s ability to effectively manage exposure to changes in interest rates. Consequently, they can often be a volatile part of IBCP’s overall revenues. IBCP realized net gains of $8.9 million on mortgage loans during the first nine months of 2017 compared to $7.7 million during the first nine months of 2016, and IBCP realized net gains of $10.6 million on mortgage loans during 2016 compared to $7.4 million during 2015 and $5.6 million during 2014.

IBCP is subject to liquidity risk in its operations, which could adversely impact its ability to fund various obligations.

Liquidity risk is the possibility of being unable to meet obligations as they come due or capitalize on growth opportunities as they arise because of an inability to liquidate assets or obtain adequate funding on a timely basis, at a reasonable cost and within acceptable risk tolerances. Liquidity is required to fund various obligations, including credit obligations to borrowers, loan originations, withdrawals by depositors, repayment of debt, dividends to shareholders, operating expenses and capital expenditures. Liquidity is derived primarily from retail deposit growth and earnings retention, principal and interest payments on loans and investment securities, net cash provided from operations and access to other funding. If IBCP is unable to maintain adequate liquidity, then its business, financial condition and results of operations could be negatively impacted.

IBCP must rely on dividends or returns of capital from its subsidiary bank for most of its cash flow.

IBCP is a separate and distinct legal entity from its subsidiary bank, Independent Bank. Generally, the parent company receives substantially all of its cash flow from dividends or returns of capital from the subsidiary bank. These dividends or returns of capital are the principal source of funds to pay the parent company’s operating expenses and for cash dividends on its common stock. Various federal and/or state laws and regulations limit the amount of dividends that the bank may pay to the parent company.

Any future strategic acquisitions or divestitures may present certain risks to IBCP’s business and operations.

Difficulties in capitalizing on the opportunities presented by a future acquisition may prevent IBCP from fully achieving the expected benefits from the acquisition, or may cause the achievement of such expectations to take longer to realize than expected. Further, the assimilation of the acquired entity’s customers and markets could result in higher than expected deposit attrition, loss of key employees, disruption of IBCP’s businesses or the businesses of the acquired entity or otherwise adversely affect IBCP’s ability to maintain relationships with customers and employees or achieve the anticipated benefits of the acquisition. These matters could have an adverse effect on IBCP for an undetermined period. IBCP will be subject to similar risks and difficulties in connection with any future decisions to downsize, sell or close units or otherwise change its business mix.

Compliance with new capital requirements may adversely affect IBCP.

The capital requirements applicable to IBCP as a bank holding company as well as to its subsidiary bank have been substantially revised in connection with Basel III and the requirements of the Financial Reform Act. These more stringent capital requirements, and any other new regulations, could adversely affect IBCP’s ability to pay dividends in the future, or could require it to reduce business levels or to raise capital, including in ways that may adversely affect its results of operations or financial condition and/or existing shareholders. The ultimate impact of the new

capital requirements cannot be determined at this time and will depend on a number of factors, including treatment and implementation by the U.S. bank regulators. However, maintaining higher levels of capital may reduce IBCP’s profitability and otherwise adversely affect its business, financial condition, or results of operations.

Declines in the businesses or industries of IBCP’s customers could cause increased credit losses, which could adversely affect IBCP.

IBCP’s business customer base consists, in part, of customers in volatile businesses and industries such as the automotive production industry and the real estate business. These industries are sensitive to global economic conditions and supply chain factors. Any decline in one of those customers’ businesses or industries could cause increased credit losses, which in turn could adversely affect IBCP.

The introduction, implementation, withdrawal, success and timing of business initiatives and strategies may be less successful or may be different than anticipated, which could adversely affect IBCP’s business.

IBCP makes certain projections and develops plans and strategies for its banking and financial products. If IBCP does not accurately determine demand for or changes in its banking and financial product needs, it could result in IBCP incurring significant expenses without the anticipated increases in revenue, which could result in a material adverse effect on its business.

IBCP may not be able to utilize technology to efficiently and effectively develop, market, and deliver new products and services to its customers.

The financial services industry experiences rapid technological change with regular introductions of new technology-driven products and services. The efficient and effective utilization of technology enables financial institutions to better serve customers and to reduce costs. IBCP’s future success depends, in part, upon its ability to address the needs of its customers by using technology to market and deliver products and services that will satisfy customer demands, meet regulatory requirements, and create additional efficiencies in its operations. IBCP may not be able to effectively develop new technology-driven products and services or be successful in marketing or supporting these products and services to its customers, which could have a material adverse impact on its financial condition and results of operations.

Operational difficulties, failure of technology infrastructure or information security incidents could adversely affect IBCP’s business and operations.

IBCP is exposed to many types of operational risk, including reputational risk, legal and compliance risk, the risk of fraud or theft by employees or outsiders, failure of its controls and procedures and unauthorized transactions by employees or operational errors, including clerical or recordkeeping errors or those resulting from computer or telecommunications systems malfunctions. Given the high volume of transactions IBCP processes, certain errors may be repeated or compounded before they are identified and resolved. In particular, IBCP’s operations rely on the secure processing, storage and transmission of confidential and other information on its technology systems and networks. Any failure, interruption or breach in security of these systems could result in failures or disruptions in its customer relationship management, general ledger, deposit, loan and other systems.

IBCP also faces the risk of operational disruption, failure or capacity constraints due to its dependency on third party vendors for components of its business infrastructure, including its core data processing systems which are largely outsourced. While IBCP has selected these third party vendors carefully, it does not control their operations. As such, any failure on the part of these business partners to perform their various responsibilities could also adversely affect IBCP’s business and operations.

IBCP may also be subject to disruptions of its operating systems arising from events that are wholly or partially beyond its control, which may include, for example, computer viruses, cyberattacks, spikes in transaction volume and/or customer activity, electrical or telecommunications outages, or natural disasters. Although IBCP has programs in place related to business continuity, disaster recovery and information security to maintain the confidentiality, integrity, and availability of its systems, business applications and customer information, such disruptions may give rise to interruptions in service to customers and loss or liability to IBCP.

The occurrence of any failure or interruption in IBCP’s operations or information systems, or any security breach, could cause reputational damage, jeopardize the confidentiality of customer information, result in a loss of customer business, subject IBCP to regulatory intervention or expose it to civil litigation and financial loss or liability, any of which could have a material adverse effect on IBCP.

Changes in the financial markets, including fluctuations in interest rates and their impact on deposit pricing, could adversely affect IBCP’s net interest income and financial condition.

The operations of financial institutions such as IBCP are dependent to a large degree on net interest income, which is the difference between interest income from loans and investments and interest expense on deposits and borrowings. Prevailing economic conditions, the trade, fiscal and monetary policies of the federal government and the policies of various regulatory agencies all affect market rates of interest and the availability and cost of credit, which in turn significantly affect financial institutions’ net interest income. Volatility in interest rates can also result in disintermediation, which is the flow of funds away from financial institutions into direct investments, such as federal government and corporate securities and other investment vehicles, which, because of the absence of federal insurance premiums and reserve requirements, generally pay higher rates of return than financial institutions. IBCP’s financial results could be materially adversely impacted by changes in financial market conditions.

Competitive product and pricing pressures among financial institutions within IBCP’s markets may change.

IBCP operates in a very competitive environment, which is characterized by competition from a number of other financial institutions in each market in which it operates. IBCP competes with large national and regional financial institutions and with smaller financial institutions in terms of products and pricing. If IBCP is unable to compete effectively in products and pricing in its markets, business could decline, which could have a material adverse effect on IBCP’s business, financial condition or results of operations.

Changes in customer behavior may adversely impact IBCP’s business, financial condition and results of operations.

IBCP uses a variety of methods to anticipate customer behavior as a part of its strategic planning and to meet certain regulatory requirements. Individual, economic, political, industry-specific conditions and other factors outside of its control, such as fuel prices, energy costs, real estate values or other factors that affect customer income levels, could alter predicted customer borrowing, repayment, investment and deposit practices. Such a change in these practices could materially adversely affect IBCP’s ability to anticipate business needs and meet regulatory requirements.

Further, difficult economic conditions may negatively affect consumer confidence levels. A decrease in consumer confidence levels would likely aggravate the adverse effects of these difficult market conditions on IBCP, its customers and others in the financial institutions industry.

IBCP’s ability to maintain and expand customer relationships may differ from expectations

The financial services industry is very competitive. IBCP not only vies for business opportunities with new customers, but also competes to maintain and expand the relationships it has with its existing customers. While IBCP believes that it can continue to grow many of these relationships, IBCP will continue to experience pressures to maintain these relationships as its competitors attempt to capture its customers. Failure to create new customer relationships and to maintain and expand existing customer relationships to the extent anticipated may adversely impact IBCP’s earnings.

IBCP’s ability to retain key officers and employees may change.

IBCP’s future operating results depend substantially upon the continued service of its executive officers and key personnel. IBCP’s future operating results also depend in significant part upon its ability to attract and retain qualified management, financial, technical, marketing, sales and support personnel. Competition for qualified personnel is intense, and IBCP cannot ensure success in attracting or retaining qualified personnel. There may be only a limited number of persons with the requisite skills to serve in these positions, and it may be increasingly difficult for IBCP to hire personnel over time.

Further, IBCP’s ability to retain key officers and employees may be impacted by legislation and regulation affecting the financial services industry. IBCP’s business, financial condition or results of operations could be materially adversely affected by the loss of any key employees, or its inability to attract and retain skilled employees.

Legal and regulatory proceedings and related matters with respect to the financial services industry, including those directly involving IBCP, could adversely affect it or the financial services industry in general.

IBCP has been, and may in the future be, subject to various legal and regulatory proceedings. It is inherently difficult to assess the outcome of these matters, and there can be no assurance that IBCP will prevail in any

proceeding or litigation. Any such matter could result in substantial cost and diversion of IBCP’s efforts, which by itself could have a material adverse effect on IBCP’s financial condition and operating results. Further, adverse determinations in such matters could result in actions by IBCP’s regulators that could materially adversely affect its business, financial condition or results of operations.

Methods of reducing risk exposures might not be effective.

Instruments, systems and strategies used to hedge or otherwise manage exposure to various types of credit, market and liquidity, operational, compliance, business risks and enterprise-wide risk could be less effective than anticipated. As a result, IBCP may not be able to effectively mitigate its risk exposures in particular market environments or against particular types of risk, which could have a material adverse impact on its business, financial condition or results of operations.

Terrorist activities or other hostilities may adversely affect the general economy, financial and capital markets, specific industries, and IBCP.

Terrorist attacks or other hostilities may disrupt IBCP’s operations or those of its customers. In addition, these events have had and may continue to have an adverse impact on the U.S. and world economies in general and consumer confidence and spending in particular, which could harm IBCP’s operations. Any of these events could increase volatility in the U.S. and world financial markets, which could harm IBCP’s stock price and may limit the capital resources available to it and its customers. This could have a material adverse impact on IBCP’s operating results, revenues and costs and may result in increased volatility in the market price of its common stock.

Catastrophic events, including, but not limited to, hurricanes, tornadoes, earthquakes, fires and floods, may adversely affect the general economy, financial and capital markets, specific industries, and IBCP.

IBCP has significant operations and a significant customer base in Michigan where natural and other disasters may occur, such as tornadoes and floods. These types of natural catastrophic events at times have disrupted the local economy, IBCP’s business, and IBCP’s customers and have posed physical risks to its property. In addition, catastrophic events occurring in other regions of the world may have an impact on IBCP’s customers and in turn, on IBCP. A significant catastrophic event could materially adversely affect IBCP’s operating results.

Changes in accounting standards could materially impact IBCP’s financial statements.

From time to time, changes are made to the financial accounting and reporting standards that govern the preparation of IBCP’s financial statements. These changes can be difficult to predict and can materially impact how IBCP records and reports its financial condition and results of operations. In some cases, IBCP could be required to apply a new or revised standard retroactively, resulting in changes to previously reported financial results, or a cumulative charge to accumulated deficit.

IBCP’s failure to appropriately apply certain critical accounting policies could result in a misstatement of its financial results and condition.

Accounting policies and processes are fundamental to how IBCP records and reports its financial condition and results of operations. IBCP must exercise judgment in selecting and applying many of these accounting policies and processes so they comply with U.S. GAAP. In some cases, IBCP 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 IBCP reporting materially different results than would have been reported under a different alternative.

IBCP has identified certain accounting policies as being critical because they require IBCP 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. IBCP has 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, IBCP cannot guarantee that it will not be required to adjust accounting policies or restate prior period financial statements. See note #1, “Accounting Policies” in the Notes to Consolidated Financial Statements included in the financial schedules delivered with this prospectus and proxy statement.

The trading price of IBCP’s common stock may be subject to significant fluctuations and volatility.

The market price of IBCP’s common stock could be subject to significant fluctuations due to, among other things:

Risks Related to Proposed Merger

The value of the Merger Consideration will fluctuate with the price of IBCP common stock.

Upon completion of the merger, each share of TCSB common stock will be converted into the right to receive the Merger Consideration.

Except as provided in the merger agreement, there will be no adjustment made to the Merger Consideration as a result of fluctuations in the market price of IBCP common stock or the value of TCSB common stock. As a result, it is possible that the value of any IBCP common stock you receive in the merger will be different than the value of such shares on the date that the TCSB board of directors adopted the merger agreement, on the date of the information concerning stock value presented in this prospectus and proxy statement, and on the date that you vote to approve the merger agreement. Stock price changes may result from a variety of factors, including general market and economic conditions, changes in IBCP’s business, operations and prospects, and regulatory considerations. Many of these factors are beyond IBCP’s control. Accordingly, at the time of the special meeting, you will not necessarily know or be able to calculate the exact value of the shares of IBCP common stock you will receive upon completion of the merger. You should obtain current market quotations for shares of IBCP common stock.

In addition, the Merger Consolidation is subject to adjustment in certain circumstances. See “What TCSB Shareholders will Receive in the Merger” on page 41 below.

Regulatory approvals may not be received, may take longer to receive than expected, or may impose conditions that are not presently anticipated.

Before the transactions contemplated in the merger agreement may be completed, regulatory approvals must be obtained from the Federal Reserve Board and the Michigan Department of Insurance and Financial Services. These governmental entities will consider, among other factors, the competitive impact of the merger, IBCP’s financial and managerial resources, the convenience and needs of the communities to be served, capital position, safety and soundness, legal and regulatory compliance matters, and Community Reinvestment Act matters, and they may impose conditions on the completion of the merger or require changes to the terms of the merger agreement. There can be no assurance as to whether regulatory approvals will be received, the timing of those approvals, or whether any conditions will be imposed.

Each party is subject to business uncertainties and contractual restrictions while the merger is pending, which could adversely affect each party’s business and operations.

Uncertainty about the effect of the merger on employees and customers may have an adverse effect on TCSB and IBCP. These uncertainties may impair TCSB’s ability to attract, retain and motivate key personnel until the merger is consummated. Retention of certain employees by TCSB may be challenging during the pendency of the merger, as certain employees may experience uncertainty about their future roles with IBCP or TCSB. If key employees depart because of issues relating to the uncertainty and difficulty of integration or a desire not to remain with IBCP, IBCP’s business following the merger could be harmed. In addition, uncertainties related to the merger could cause customers and others that deal with TCSB or IBCP to seek to change existing business relationships with TCSB or IBCP, or delay or defer certain business decisions with respect to TCSB or IBCP, which could negatively affect IBCP’s or TCSB’s respective revenues, earnings and cash flows, as well as the market price of IBCP common stock or the value of TCSB common stock, regardless of whether the merger is completed. Furthermore, the merger agreement restricts TCSB from taking specified actions without the consent of IBCP until the merger occurs or the merger agreement is terminated. These restrictions may prevent TCSB from pursuing attractive business opportunities that may arise prior to the completion of the merger. See “The Merger Agreement – Conduct of Business Pending the Merger” for a summary of certain of the contractual restrictions to which TCSB is subject.

Combining the two companies may be more difficult, costly, or time-consuming than expected.

The difficulties of merging the operations of TCSB with those of IBCP include, among others, integrating personnel with diverse business backgrounds, combining different corporate cultures, retaining key employees, and converting operating systems. The process of integrating operations could cause an interruption of, or loss of momentum in, the activities of the companies, and the loss of key personnel. The diversion of management’s attention and any delays or difficulties encountered in connection with the merger and integration of TCSB into IBCP could have an adverse effect on the business and results of operations of TCSB or IBCP. As with any merger of banking institutions, there also may be business disruptions that cause the banks to lose customers or cause customers to take their deposits out of the banks. The success of the combined company following the merger may depend in large part on the ability to integrate the two businesses, business models and cultures. Inability to integrate our operations successfully and in a timely manner could result in the expected benefits of the merger not being realized.

TCSB shareholders’ percentage ownership of IBCP will be much smaller than their percentage ownership of TCSB.

TCSB shareholders currently have the right to vote in the election of the TCSB board of directors and on other matters affecting TCSB. When the merger occurs, each TCSB shareholder will become a shareholder of IBCP with a percentage ownership of the combined organization that is much smaller than the shareholder’s percentage ownership of TCSB. Because of this, the TCSB shareholders will have less influence on the management and policies of IBCP than they now have on the management and policies of TCSB.

Directors and officers of TCSB have interests in the merger that differ from the interests of non-director or non-management shareholders.

Some of the directors and officers of TCSB have interests in the merger that differ from, or are in addition to, their interests as shareholders of TCSB generally. These interests exist because of, among other things, employment or severance agreements that the officers entered into with TCSB, rights that TCSB officers and directors have under TCSB’s benefit plans, and rights to indemnification and directors’ and officers’ insurance following the merger. The members of each of TCSB’s and IBCP’s boards of directors knew about these additional interests and considered them when they adopted the merger agreement and approved the merger. For a more detailed discussion of these interests, see “Interests of Certain Directors and Executive Officers in the Merger.”

The merger agreement limits TCSB’s ability to pursue alternatives to the merger.

The merger agreement contains provisions that limit TCSB’s ability to encourage or consider competing third-party proposals to acquire TCSB, all or a significant part of its assets or stock, or other similar business combinations. These provisions, which include a $2,529,658 termination fee payable to IBCP under certain circumstances, might discourage a potential competing acquirer that might have an interest in acquiring all or a significant part of TCSB from considering or proposing that acquisition even if it were prepared to pay consideration

with a higher per share price than that proposed in the merger, or might result in a potential competing acquirer proposing to pay a lower per share price to acquire TCSB than it might otherwise have proposed to pay. See “The Merger Agreement – Acquisition Proposals by Third Parties” and “The Merger Agreement – Termination Fee.”

The merger agreement may be terminated in accordance with its terms and the merger may not be completed, which could have a negative impact on TCSB.

The merger agreement is subject to a number of conditions that must be fulfilled in order to complete the merger. Those conditions include completion of the merger by September 4, 2018, receipt of TCSB shareholder approval, receipt of regulatory approvals, continued accuracy of certain representations and warranties by both parties, and performance by both parties of certain covenants and agreements. In addition, the merger agreement may be terminated in certain circumstances. In particular, IBCP is not obligated to complete the merger if the Company Consolidated Shareholders’ Equity is less than $33,000,000 as of the Final Statement Date.

If the merger agreement is terminated, there may be various consequences to TCSB, including:

If the merger agreement is terminated and the TCSB board of directors seeks another merger or business combination, under certain circumstances, TCSB is required to pay IBCP a $2,529,658 termination fee. TCSB shareholders cannot be certain that TCSB would be able to find a party willing to pay an equivalent or more attractive price than the price IBCP has agreed to pay in the merger.

IBCP may fail to realize the cost savings estimated for the merger.

IBCP expects to achieve cost savings from the merger when the two companies have been fully integrated. The cost savings estimates assume the ability to combine the businesses of IBCP and TCSB in a manner that permits those cost savings to be realized. If the estimates turn out to be incorrect or if IBCP is not able to combine successfully the two companies, the anticipated cost savings may not be fully realized or realized at all, or may take longer to realize than expected.

The fairness opinion obtained by TCSB from its financial advisor will not reflect changes between the date of the opinion and the effective time of the merger.

D.A. Davidson & Co., the financial advisor to TCSB, has delivered a “fairness opinion” to the board of directors of TCSB. The opinion of DADCO is directed to the board of directors of TCSB and is not a recommendation to any shareholder on how to vote on the merger agreement or any other matter. The opinion, which was issued on December 4, 2017, states that, based upon and subject to the assumptions and limitations on review set forth in the opinion, the Exchange Ratio is fair, from a financial point of view, to TCSB. The opinion does not reflect changes that may occur or may have occurred after the date of the opinion, and therefore does not address the fairness of the Exchange Ratio as of the date of this prospectus and proxy statement, the date of the special meeting, or at the time the merger will be completed.

The merger may fail to qualify as a reorganization for federal income tax purposes, resulting in your recognition of taxable gain or loss in respect of all of your TCSB common stock.

IBCP and TCSB intend for the merger to qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”). The Internal Revenue Service (“IRS”) will not provide a ruling on the matter. IBCP and TCSB each will, as a condition to closing, obtain an opinion from counsel that the merger will constitute a reorganization for federal income tax purposes. However, these opinions do not bind the IRS or prevent the IRS from adopting a contrary position. If the merger fails to qualify as a reorganization, TCSB shareholders generally would recognize gain or loss on each share of TCSB common stock surrendered in an amount equal to the difference between the shareholder’s adjusted tax basis in that share and the fair market value of the IBCP common stock received in exchange for that share upon completion of the merger. See “Proposal 1 – The Merger – Material United States Federal Income Tax Consequences” on page 39.

The shares of IBCP common stock to be received by TCSB shareholders as a result of the merger will have different rights from the shares of TCSB common stock.

The rights associated with TCSB common stock are different from the rights associated with IBCP common stock. See “Comparison of Common Shareholder Rights” for a discussion of the different rights associated with IBCP common stock as compared to TCSB common stock.

Litigation may be filed against TCSB, its board of directors, and/or IBCP that could prevent or delay the completion of the merger or result in the payment of damages following completion of the merger.

In connection with the merger, it is possible that TCSB shareholders may file putative shareholder class action lawsuits against TCSB, its board of directors, and/or IBCP. Among other remedies, the plaintiffs may seek to enjoin the merger. The outcome of any such litigation is uncertain. If a dismissal is not granted or a settlement is not reached, such potential lawsuits could prevent or delay completion of the merger and result in substantial costs to TCSB and IBCP, including any costs associated with indemnification. The defense or settlement of any lawsuit or claim that remains unresolved at the time the merger is consummated may adversely affect TCSB’s and IBCP’s business, financial condition, results of operations, cash flows and market price.

TCSB SPECIAL MEETING AND GENERAL PROXY INFORMATION

Date, Time, Place, and Purpose

The TCSB board of directors is sending you this prospectus and proxy statement and proxy to use at the special meeting. At the special meeting, the TCSB board of directors will ask you to vote (1) to approve the merger agreement and (2) to approve the Adjournment Proposal.

The special meeting will be held on [•], 2018, at [•], local time, at [•], [•], Michigan [•].

Recommendation of TCSB’s Board of Directors

TCSB’s board of directors has unanimously determined that the merger is in substantial compliance with all applicable laws and is fair to and in the best interests of TCSB and TCSB’s shareholders, adopted the merger agreement and authorized the merger and the other transactions contemplated by the merger agreement, and unanimously recommends that TCSB shareholders vote “FOR” approval of the merger agreement and “FOR” the Adjournment Proposal.

Voting by Proxy; Record Date

TCSB’s board of directors has designated [•], 2018, as the record date for determination of shareholders entitled to notice of and to vote at the special meeting. As of the record date, [•] shares of TCSB common stock were issued and outstanding and held by approximately [•] record holders. TCSB shareholders are entitled to one vote on each matter considered and voted on at the special meeting for each share of TCSB common stock held of record at the close of business on the record date. If a holder of shares of TCSB common stock as of the record date properly submits a proxy, the shares represented by that proxy will be voted at the special meeting and at any adjournment of that meeting. If a shareholder specifies a choice, the proxy will be voted in accordance with the shareholder’s specification. If no specification is made, your shares of TCSB common stock represented by your proxy will be voted “FOR” approval of the merger agreement and “FOR” approval of the Adjournment Proposal.

TCSB’s management currently is not aware of any other matter to be presented at the special meeting. If other matters are presented, the shares for which proxies have been received will be voted in accordance with the discretion of the persons named as proxies.

Revocation of Proxies

A TCSB shareholder who has given a proxy may revoke it at any time before its exercise at the special meeting by one of three ways. First, you may send a written notice to the President and Chief Financial Officer of TCSB, Ann Bollinger, 333 West Grandview Parkway, Traverse City, Michigan 49684, stating that you would like to revoke your proxy. Second, you may complete and submit a new proxy, dated at a date later than your most recent proxy. Third, you may attend the special meeting and vote in person. Your attendance at the special meeting will not, however, by itself revoke your proxy. If you have instructed a broker to vote your shares, you must follow the directions you receive from your broker to change your vote. Your last vote will be the vote that is counted.

Proxy Solicitation

The board of directors and management of TCSB will initially solicit proxies by mail. If they deem it advisable, directors, officers, and employees of TCSB may also solicit proxies in person, by telephone or by electronic means without additional compensation. In addition, nominees and other fiduciaries may solicit proxies. Such persons may, at the request of TCSB’s management, mail material to or otherwise communicate with the beneficial owners of shares held by them.

Expenses

Except for internal costs and fees of TCSB, IBCP will pay all expenses incurred in connection with the solicitation of proxies of TCSB shareholders. IBCP will pay all expenses incurred in connection with the printing and mailing of this prospectus and proxy statement and all filing costs associated with the registration statement and the applications for regulatory approval. Otherwise, IBCP and TCSB will each pay their own fees and expenses incident to preparing for, entering into, and carrying out the merger agreement and procuring any necessary approvals, including fees and expenses of its own legal counsel and accountants and postage expenses.

Quorum

The presence, in person or by proxy, of the holders of a majority of the votes entitled to be cast by the TCSB shareholders at the special meeting is necessary to constitute a quorum. Abstentions will be counted as present and entitled to vote for purposes of determining a quorum.

Vote Required for Approval; Voting Agreement

The affirmative vote of the holders of a majority of the shares of TCSB common stock outstanding as of the record date for the special meeting is required to approve the merger agreement. Because the required vote of TCSB shareholders on the merger agreement is based upon the number of outstanding shares of TCSB common stock entitled to vote rather than upon the number of shares actually voted, a failure to vote and abstentions will have the same practical effect as a vote against approval of the merger agreement. The affirmative vote of the holders of a majority of votes cast at the special meeting is necessary to approve the Adjournment Proposal. A failure to vote and abstentions will have no effect on this proposal. No approval by IBCP shareholders is required.

As of the record date, TCSB’s directors, executive officers, and their affiliates beneficially owned [•] shares of TCSB common stock, or approximately [•]% of the shares of TCSB common stock entitled to vote at the special meeting. Each of TCSB’s directors has entered into a voting agreement pursuant to which he or she has agreed, subject to certain exceptions, to vote his or her shares, and to use reasonable efforts to cause all shares owned by such director jointly with another person or by such director’s spouse or over which such director has voting influence or control to be voted, in favor of approval of the merger agreement.

PROPOSAL 1 – THE MERGER

The following discussion summarizes certain aspects of the merger. This summary discussion does not purport to be a complete description of the merger and is qualified in its entirety by reference to the merger agreement, which is attached as Appendix A to this prospectus and proxy statement and incorporated herein by reference into this prospectus and proxy statement.

Background of the Merger

TCSB’s Board of Directors and management regularly evaluate and assess TCSB’s strategy and opportunities to strengthen its business and achieve profitable growth and value for its shareholders through various strategic initiatives, alternatives and transactions, giving consideration to the context of developments in the banking industry, including industry consolidation, the regulatory environment, conditions in the markets that TCSB serves, competitive considerations and other factors. TCSB’s board of directors regularly reviews the company’s performance, risks, opportunities, stock valuation, capital needs and strategy and discusses these matters at meetings.

When considering strategic alternatives from time to time, management and the board of directors examined the possibility of acquiring other institutions to gain additional profitability through scale. However, opportunities were limited due in large part to the existence of very few banks of a smaller, realistic size which were available for potential acquisition and in attractive markets.

Management and the board of directors also regularly considered the merits of maintaining an independence strategy versus the opportunity to pursue additional shareholder value through the sale of TCSB. The independence strategy was maintained in recent years due to, among other things, the strong financial performance of TCSB and its prospects for generating additional shareholder value through organic growth.

However, for several years, the board of directors has viewed the general lack of liquidity and market in TCSB common stock as a weakness to the independence strategy. Shares of TCSB common stock are not traded in an established market. They are traded infrequently and generally in private transactions between individuals.

In addition, during the years since the financial crisis, management and the board of directors assessed significant operating risk increases in the banking industry. Specifically, costs associated with increasing compliance and safety and soundness regulatory burdens, necessary technology enhancements, cybersecurity risks and increasing competition were noted as challenges to a continued independence strategy. The board of directors also began to recognize and discuss that as the financial performance, market share and reputation of TCSB continued to grow, so too did the prospects and rationale for pursuing a potential sale of the company, including that combining with a larger company would increase scale, scope, strength and diversity of operations, product lines and delivery systems and enhance the ability to provide more comprehensive financial services and higher loan limits.

On March 22, 2017, the board of directors held its annual strategic planning meeting. All of these factors combined led the board of directors to serious consideration of whether the present independence strategy should be retained or modified to seek a strategic partnership through a potential sale of TCSB. Based on, among other things, TCSB’s internal strengths (solid financial performance and metrics, low levels of classified assets, excellent sales force and projected growth rates) combined with optimism in the political and economic climate (rising interest rates, presumed softening of the bank regulatory environment and potential corporate income tax cuts), the board of directors unanimously determined to preliminarily explore the possibility of selling TCSB in the relative near-term. The board of directors authorized management to consult with its corporate counsel, Warner Norcross & Judd LLP (“Warner Norcross”), to provide guidance on the initial phases of a potential sales process and to explore the engagement of an investment banking firm to act as financial advisor to TCSB in connection with a potential sale of the company.

On May 16, 2017, the board of directors held a special meeting. A representative of Warner Norcross attended the meeting. In addition, representatives of two investment banking firms (D.A. Davidson & Co. (“DADCO”) and another reputable firm) separately attended the meeting and gave detailed presentations to the board of directors, which addressed, among other things: the firm’s industry experience and qualifications in M&A transactions; recent stock market performance, with an emphasis on the financial institutions sector; factors influencing the M&A market for community banks; precedent M&A transactions; M&A valuation of TCSB as of May 16, 2017 based on precedent M&A transactions, ability-to-pay analysis and net present value analysis; select potential merger partners, including considerations for evaluation of each potential merger partner; overview of a sales process (which included various different approaches) and timeline; considerations of stock versus cash as transaction consideration; and the firm’s fee proposal.

Warner Norcross advised of the fiduciary and legal obligations applicable to directors when considering a merger or sale of TCSB. Warner Norcross also reviewed Article XI (Business Combinations) of TCSB’s articles of incorporation, which requires the board of directors, when considering a business combination transaction, to first conclude that the transaction would be in substantial compliance with all applicable laws, and second conclude that the transaction would be in the best interests of the corporation and its shareholders, based on relevant factors, including: the fairness of the consideration to be received; the possible social and economic impact on TCSB, its employees and customers and the communities it serves; the business, financial condition, safety and soundness and prospects of the offering party; the competence, experience and integrity of the offering party and its management; and the intentions of the offering party regarding the operation of TCSB after completion of the transaction (“Article XI Factors”).

The board of directors extensively discussed a potential sale of TCSB and the presentations from the investment banking firms. Following the discussion, the board of directors unanimously authorized continuation of exploration of a potential sale of TCSB. The board of directors elected to defer the selection of an investment banking firm to act as financial advisor to a later date to allow directors additional time to review and consider the information provided by the two investment banking firms.

On May 23, 2017, the board of directors held a regular meeting. Following discussion, the board of directors unanimously approved the engagement of DADCO to act as financial advisor to TCSB in connection with a potential sale of the company and authorized management to proceed to negotiate a definitive engagement letter with DADCO. In approving the engagement of DADCO, the board of directors considered, among other things, the type and amount of DADCO’s fees, DADCO’s expertise in advising financial institutions, including in M&A transactions, and DADCO’s professional reputation. In addition, the board of directors designated and appointed a special committee, consisting of Directors Dickinson, Pangborn and Weigel, to act on behalf of the board of directors on all matters relating to a potential sale of TCSB, if necessary.

On June 5, 2017, the special committee held a meeting. A representative from Warner Norcross attended the meeting. Warner Norcross reviewed the terms of a proposed definitive engagement letter with DADCO. The special committee instructed Warner Norcross to negotiate certain changes to the engagement letter and authorized management to execute the engagement letter, subject to the negotiation of the requested changes.

On June 13, 2017, TCSB executed a definitive engagement letter with DADCO to act as financial advisor to TCSB in connection with a potential sale of the company.

On June 29, 2017, the board of directors held a special meeting. A representative of Warner Norcross and a representative of DADCO attended the meeting. DADCO presented select potential merger partners, which included

21 institutions located in Michigan, Indiana and Wisconsin. For each potential merger partner, DADCO reviewed general company information, financial information, including select income statement and balance sheet information, financial performance ratios, deposit and loan composition, stock performance, capacity to pay analysis and summary historical M&A transactions (if any). DADCO presented the potential merger partners in three tiers – Tier 1 being the most likely merger partners, Tier 2 being moderately likely merger partners and Tier 3 being the least likely merger partners. DADCO also reviewed various different approaches to a proposed sales process and a timeline.

Warner Norcross advised of the fiduciary and legal obligations applicable to directors when considering a merger or sale of TCSB and reviewed the Article XI factors.

The board discussed in detail the select potential merger partners and the various different approaches to a sales process. Following the discussion, the board of directors authorized DADCO to approach 12 potential merger partners to gauge their interest in a potential merger with TCSB. The board of directors also approved the preparation and delivery of a confidential information memorandum (“CIM”) about TCSB to, and the preparation, negotiation and entering into of a non-disclosure agreement (“NDA”) with, each selected potential merger partner.

Beginning in late July, 2017, DADCO contacted the 12 potential merger partners to gauge their interest in a potential merger with TCSB and presented each with a NDA for execution. Seven potential merger partners expressed interest in a potential merger with TCSB and executed a NDA. The remaining five potential merger partners declined any interest in a potential merger with TCSB and did not execute a NDA. In early August, 2017, DADCO sent the CIM to each of the remaining seven potential merger partners and invited each to submit a written, preliminary indication of interest in a potential merger with TCSB. Shortly after delivery of the CIM, two of the potential merger partners declined any further interest in a potential merger with TCSB. At the end of August, 2017 and the beginning of September, 2017, all of the remaining five potential merger partners submitted written, preliminary indications of interest in a potential merger with TCSB.

On September 7, 2017, the board of directors held a special meeting. A representative of Warner Norcross and a representative of DADCO attended the meeting. Warner Norcross advised of the fiduciary and legal obligations applicable to directors when considering a merger or sale of TCSB and reviewed the Article XI factors. Management summarized the results of their in-person interviews with each of the remaining five potential merger partners.

DADCO presented a detailed financial presentation, which addressed, among other things: a market update since the May 16, 2017 board of directors meeting; precedent M&A transactions; overview of sales process and timeline; M&A valuation of TCSB as of May 16, 2017 based on precedent M&A transactions, ability-to-pay analysis and net present value analysis; and a summary of contact with potential merger partners, including process and responses. In addition, DADCO reviewed, in detail, the written, preliminary indications of interest in a potential merger with TCSB submitted by each of the remaining five potential merger partners, which addressed, among other things: a comparison of the terms and conditions outlined in each indication of interest, including consideration, price per share, implied transaction value and valuation ratios, exchange ratio and transaction structure; and for each potential merger partner, general company information, financial information, including select income statement and balance sheet information, financial performance ratios, deposit and loan composition, and stock performance, summary historical M&A transactions (if any) and institutional shareholder ownership.

The board extensively discussed the potential merger partners and the preliminary indications of interest. Following the discussion, the board of directors unanimously authorized continuation of the sales process and the pursuit of a potential merger with three of the five remaining potential merger partners (including IBCP, Potential Merger Partner #2 and Potential Merger Partner #3). For various reasons, the board of Directors determined it was in the best interests of TCSB and its shareholders to no longer pursue a potential merger with Potential Merger Partner #4 and Potential Merger Partner #5. In addition, the board of directors authorized commencement of due diligence of TCSB by the three remaining potential merger partners and their respective advisors and reverse due diligence of the three remaining merger partners by TCSB and its advisors and the preparation of a prototype merger agreement for delivery to the three remaining merger partners for review and comment in connection with submission of final indications of interest.

Following the September 7, 2017 board of directors meeting, each of the three remaining potential merger partners submitted due diligence request lists. TCSB established a virtual data room and began populating it. Each

of the three potential merger partners was granted access to the virtual data room to perform its due diligence review. In addition, TCSB and its advisors conducted reverse due diligence of each of the three remaining potential merger partners. Warner Norcross prepared a prototype merger agreement.

During the weeks of October 1 and 8, 2017, each of the three remaining potential merger partners separately conducted “onsite” credit due diligence of TCSB’s loan portfolio at the offices of Warner Norcross.

On October 9, 2017, Potential Merger Partner #3 informed TCSB that it was withdrawing from the process and declined any further interest in a potential merger with TCSB. Also on this date, a prototype merger agreement was delivered to IBCP and Potential Merger Partner #2 for review and comment in connection with submission of final indications of interest.

On October 16, 2017, the board of directors held a special meeting. A representative of Warner Norcross and a representative of DADCO attended the meeting. Executive officers from each of IBCP and Potential Merger Partner #2 separately presented to the board of directors about their respective companies and provided their respective views on a range of topics, including considerations and investment thesis for owning shares of their respective common stock, intended plans for the integration of TCSB and its customers, employees and the communities it serves and why they should be the preferred merger partner. The board of directors engaged in an in-depth and detailed discussion about the potential merger partners and their respective presentations. Following the discussion, the board of directors authorized the continuation of the sales process and pursuit of a potential merger with IBCP and Potential Merger Partner #2.

On October 31, 2017, each of IBCP and Potential Merger Partner #2 submitted written, final indications of interest in a potential merger with TCSB and their respective comments to the prototype merger agreement. IBCP’s proposal offered merger consideration consisting of all IBCP common stock or a mix of IBCP common stock and cash, and Potential Merger Partner #2’s proposal offered merger consideration consisting of a mix of Potential Merger Partner #2 common stock and cash. IBCP’s all-stock proposal represented the distinctly higher economic value of total consideration per share proposed by each at the time.

On November 6, 2017, the board of directors held a special meeting. A representative of Warner Norcross and a representative of DADCO attended the meeting. Warner Norcross reviewed the status of reverse due diligence on IBCP and Potential Merger Partner #2 to date and the Article XI factors, and advised of the fiduciary and legal obligations applicable to directors when considering a merger or sale of TCSB. Warner Norcross also summarized the comments of IBCP and Potential Merger Partner #2 to the prototype merger agreement.

DADCO presented a detailed financial presentation, which addressed, among other things: a market update since the September 7, 2017 board of directors meeting; precedent M&A transactions; overview of sales process and timeline; M&A valuation of TCSB as of May 16, 2017 based on precedent M&A transactions, ability-to-pay analysis and net present value analysis; and a summary of contact with potential merger partners, including process and responses. In addition, DADCO reviewed, in detail, the written, final indications of interest in a potential merger with TCSB submitted by IBCP and Potential Merger Partner #2, which addressed, among other things: a comparison of the terms and conditions outlined in each indication of interest, including consideration, price per share, implied transaction value and valuation ratios, exchange ratio and transaction structure; and for each potential merger partner, general company information, financial information, including select income statement and balance sheet information, financial performance ratios, deposit and loan composition, stock performance, liquidity and dividend analysis, peer analysis, summary historical M&A transactions (if any), institutional shareholder ownership and the potential for the sale of the potential merger partner following completion of a merger with TCSB.

The board of directors engaged in an in-depth and detailed discussion on a range of topics, including, among other things: the perceived relative advantages and disadvantages of each potential merger partner as a merger partner, focusing primarily on the Article XI factors and without regard to the value of the merger consideration proposed by each; the business and prospects of each and how TCSB’s business would align; the perceived relative merits of owning the common stock of each; the perceived market reaction to a merger transaction between TCSB and each; and the value of the merger consideration proposed by each (it was noted that IBCP’s all-stock proposal represented the distinctly higher economic value of total consideration per share proposed by each at the time). After the discussion, the board of directors unanimously determined that IBCP was an acceptable merger partner and that IBCP’s final indication of interest was an acceptable proposal, subject to a request that IBCP permit one TCSB

director to serve on IBCP’s board of directors following completion of the merger. Following IBCP’s agreement to this request, which was obtained during the course of the meeting, the board of directors authorized management to proceed to negotiate a definitive merger agreement with IBCP substantially on the basis set forth in IBCP’s final indication of interest.

During the time period beginning on November 7, 2017 and ending on December 4, 2017, Warner Norcross and Varnum LLP (legal counsel to IBCP), with the participation of DADCO and management, proceeded to negotiate a definitive merger agreement. Multiple drafts of the merger agreement were exchanged between Warner Norcross and Varnum LLP and several negotiating sessions occurred. Also, during this time period, each party completed due diligence and prepared, circulated and finalized its disclosure letter listing certain supplements and exceptions to the representations and warranties and covenants contained in the merger agreement.

On December 4, 2017, the board of directors held a special meeting. A representative of Warner Norcross and a representative of DADCO attended the meeting. Warner Norcross advised that a proposed merger agreement had been successfully negotiated and would be presented for adoption by the board of directors at the meeting. Warner Norcross reviewed the status and findings of reverse due diligence of IBCP to date and the Article XI factors, advised of the fiduciary and legal obligations applicable to directors when considering a merger or sale of TCSB and provided its oral opinion that the merger would be in substantial compliance with all applicable laws. Warner Norcross provided a comprehensive review of the proposed merger agreement, including customary “fiduciary out” provisions in the event TCSB were to receive a superior proposal.

DADCO presented its fairness opinion analysis. This analysis included, among other things, an overview of the sales process and timeline; a review of the fairness opinion process; a summary of the terms of the proposed merger, including the merger consideration; transaction metrics, including implied valuation multiples (it was noted that, based on the price per share of IBCP common stock as of market close on November 27, 2017, the proposed merger represented a price to tangible book value (9/30/17) multiple of 206% and a price to earnings per share (9/30/17 LTM) multiple of 25.3x); a price sensitivity analysis; implied per share transaction value based on IBCP’s common stock performance for the last 12 months; a dividend reinvestment analysis; pro forma metrics, including the earn-back period for dilution to IBCP’s tangible book value; a contribution analysis; peer analyses; precedent M&A transactions; a net present value analysis; and financial and stock information about IBCP. DADCO delivered its oral opinion that, as of December 4, 2017, and based upon and subject to the assumptions presented, the exchange ratio (as defined in the merger agreement) to be paid in the merger was fair, from a financial point of view, to TCSB.

The board of directors engaged in an in-depth and detailed discussion about the merger agreement and the fairness opinion analysis. Following the discussion, the Board of Directors unanimously determined that the merger would be in substantial compliance with all applicable laws and in the best interests of TCSB and its shareholders, adopted the merger agreement, approved and authorized the merger and related transactions and recommended that TCSB shareholders approve the merger agreement. Following the meeting, TCSB and IBCP executed and delivered the merger agreement and respective disclosure letters.

On December 4, 2017, after the U.S. financial markets closed, TCSB and IBCP issued a joint press release announcing execution of the merger agreement and certain terms of the merger.

TCSB’s Reasons for the Merger and Recommendation of TCSB’s Board of Directors

TCSB’s board of directors has unanimously determined that the merger is in the best interests of the company and its shareholders. In adopting the merger agreement, the board of directors consulted with DADCO with respect to the financial aspects of the merger and the fairness of the exchange ratio (as defined in the merger agreement), from a financial point of view, to TCSB. The board of directors also consulted with Warner Norcross as to the merger’s substantial compliance with all applicable laws, the fiduciary and legal obligations applicable to directors when considering a merger or sale of TCSB and the terms of the merger agreement. In arriving at its determination, the board of directors considered a number of factors, including the following:
