Dear Blue Hills Bancorp, Inc. Stockholders and Independent Bank Corp. Shareholders:

We are pleased to report that the Boards of Directors of Blue Hills Bancorp, Inc. (“BHB”) and Independent Bank Corp. (“Independent”) have approved an Agreement and Plan of Merger, which is referred to as the merger agreement. Under the merger agreement, BHB will merge with and into Independent, with Independent as the surviving company in the merger. Independent and BHB cannot complete the merger transaction without the approval of both Independent shareholders and BHB stockholders.

BHB will be holding a special meeting of its common stockholders to vote on certain matters in connection with the merger and Independent will be holding a special meeting of its common shareholders to vote on certain matters in connection with the merger. Holders of shares of BHB common stock will vote at a special meeting of BHB stockholders to be held on January 16, 2019 to approve the merger agreement and to vote on a related proposal. Holders of shares of Independent common stock will vote at a special meeting of Independent common shareholders to be held on January 25, 2019 to approve the merger agreement, including the issuance of up to 6,835,690 shares of Independent common stock in connection with the merger, which is necessary to allow the merger to close, and to vote on a related proposal. The 6,835,690 shares of Independent common stock represent the maximum number of shares that would be issuable in the transaction, based on the estimated maximum number of shares of BHB common stock outstanding immediately prior to the merger, assuming that all outstanding stock options granted by BHB on the date hereof are exercised and all outstanding shares of restricted stock on the date hereof vest in accordance with their terms.

If the proposed merger is completed, BHB’s stockholders will receive in exchange for each share of BHB common stock, (i) $5.25 in cash and (ii) 0.2308 of a share of Independent common stock in accordance with the terms and conditions of the merger agreement. Independent’s and BHB’s common stock are each listed on the Nasdaq Global Select Market under the trading symbols “INDB” and “BHBK,” respectively. The closing sales prices of Independent common stock and BHB common stock on December 6, 2018, the last practicable trading day prior to the mailing of this document, were $74.72 and $22.68, respectively. The equivalent value of the consideration to be paid in the merger for each share of BHB, calculated by (i) adding $5.25 to (ii) the product obtained by multiplying the closing sales price of Independent common stock of $74.72 on December 6, 2018 by the 0.2308 exchange ratio, would be $22.50. The market prices for both Independent common stock and BHB common stock will fluctuate prior to the merger, and the market price for Independent common stock will fluctuate subsequent to the merger. We urge you to obtain current market quotations for both Independent common stock and BHB common stock.

If the market price of Independent common stock falls substantially, both in absolute terms (that is, a volume weighted average trading price below $77.07) and by comparison to a market capitalization-weighted index of the stock of banking companies that comprise the Nasdaq Bank Stock Index, BHB may terminate the merger agreement. However, if BHB seeks to exercise that termination right, Independent may negate the termination by increasing the exchange ratio from 0.2308 of a share to a formula amount determined in accordance with the merger agreement, as described in this joint proxy statement/prospectus.

We generally expect the merger to be tax-free solely with respect to the Independent common stock that BHB common stockholders receive.

Assuming the exchange ratio is 0.2308 of a share, if the merger is completed and all outstanding stock options granted by BHB on the date hereof are exercised and all outstanding shares of restricted stock on the date hereof vest in accordance with their terms prior to the closing of the merger, BHB common stockholders will own approximately 6.8 million shares, or approximately 20%, of Independent’s outstanding common stock. Independent expects substantially fewer shares of Independent common stock will be issued in the merger because not all outstanding stock options granted by BHB will be exercised before the closing of the merger. If no stock options are exercised, BHB stockholders would own approximately 18% of Independent’s common stock upon completion of the merger.

Independent and BHB cannot complete the proposed merger unless, among other conditions, BHB’s stockholders approve the merger agreement and the merger at the BHB special meeting and Independent’s

shareholders approve the merger agreement and the merger at the Independent special meeting. This letter is accompanied by BHB’s proxy statement, which BHB is providing to BHB stockholders to solicit their proxy to vote for approval of the merger agreement and the merger at the BHB special meeting, and by Independent’s proxy statement, which Independent is providing to Independent shareholders to solicit their proxy to vote for approval of the merger agreement and the merger at the Independent special meeting. The accompanying document is also being delivered to BHB’s stockholders as Independent’s prospectus for its offering of Independent common stock to BHB’s stockholders in the merger.

BHB’s board of directors has unanimously recommended that you vote “FOR” approval of the merger agreement and the transactions contemplated by the merger agreement, including the merger, at the BHB special meeting and “FOR” approval of the authorization of the board of directors of BHB to adjourn the BHB special meeting if necessary to permit further solicitation of proxies on the proposal to approve the agreement and plan of merger and to vote on other matters properly before the BHB special meeting.

Independent’s board of directors has unanimously recommended that you vote “FOR” approval of the merger agreement and the transactions contemplated by the merger agreement, including the merger and the issuance of up to 6,835,690 shares of Independent common stock in connection with the merger, at the Independent special meeting, which is necessary to allow the merger to close, and “FOR” approval of the authorization of the board of directors of Independent to adjourn the Independent special meeting if necessary to permit further solicitation of proxies on the proposals to approve the agreement and plan of merger and to vote on other matters properly before the Independent special meeting.

This joint proxy statement/prospectus provides you with detailed information about the proposed merger. It also contains or references information about Independent and BHB and related matters. You are encouraged to read this document carefully. In particular, you should read the “Risk Factors” section beginning on page 19 for a discussion of the risks you should consider in evaluating the proposed merger and how it will affect you.

Your vote is very important. Approval of the BHB merger agreement proposal will require the affirmative vote of the holders of a majority of the shares of BHB common stock outstanding and entitled to vote. Approval of the Independent merger agreement proposal will require the affirmative vote of the holders of at least two-thirds of the shares of Independent common stock outstanding and entitled to vote. Whether or not you plan to attend the BHB special meeting or Independent special meeting, as applicable, please take the time to vote by completing and mailing the enclosed proxy card. If BHB stockholders and Independent shareholders do not vote in person or by proxy, it will have the same effect as a vote against the proposal to approve the merger at the BHB special meeting or the Independent special meeting, as applicable.

Neither the Securities and Exchange Commission nor any state securities regulator has approved or disapproved the proposed merger, including the issuance of Independent common stock to be issued in connection with the merger, or the other transactions described in this joint proxy statement/prospectus, or determined if this joint proxy statement/prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

The shares of Independent common stock are not savings accounts, deposits or other obligations of any bank or savings association and are not insured by the Federal Deposit Insurance Corporation or by any other federal or state governmental agency.

This joint proxy statement/prospectus is dated [●] and is first being mailed or otherwise delivered to stockholders of BHB and shareholders of Independent on or about [●].

QUESTIONS AND ANSWERS ABOUT THE MERGER, THE BLUE HILLS BANCORP, INC. SPECIAL MEETING AND THE INDEPENDENT BANK CORP. SPECIAL MEETING

Questions and Answers About the Merger

Independent’s common stock is listed on the Nasdaq Global Select Market under the trading symbol “INDB.” Independent will not issue fractional shares of its common stock in the merger, but will instead pay cash for any fractional shares at a price determined by the volume weighted average closing price of Independent common stock on the Nasdaq Global Select Market for the five trading days ending on the fifth trading day immediately preceding the closing date of the merger, which is referred to herein as the Closing VWAP.

Stock Options: Each stock option granted by BHB will become fully vested immediately prior to the effective time of the merger. BHB stock options will be cancelled upon consummation of the merger, and each option holder will receive a cash payment upon cancellation of the BHB stock option equal to the product of (i) the number of shares of BHB common stock provided for by such stock option and (ii) the excess, if any, of $26.25 over the exercise price of such stock option. Any BHB stock option with an exercise price in excess of $26.25 will be cancelled as of the effective time of the merger without payment.

1

Restricted Stock: Each restricted share of BHB common stock will become fully vested immediately prior to the effective time of the merger. All restricted shares of BHB common stock will be treated as outstanding shares of BHB common stock for all purposes under the merger agreement, and each holder will have the right to receive the merger consideration.

Questions and Answers About the Special Meeting of BHB Stockholders

BHB’s stockholders are also being asked to authorize the board of directors of BHB to adjourn or postpone the BHB special meeting if necessary to permit further solicitation of proxies in favor of the BHB merger agreement proposal or to vote on other matters properly before the BHB special meeting. We refer to this proposal as the BHB adjournment proposal.

BHB’s board of directors also unanimously recommends that BHB’s stockholders vote “FOR” the BHB adjournment proposal.

3

Approval of the BHB adjournment proposal will require the affirmative vote of a majority of the shares voted on the BHB adjournment proposal. Abstentions and broker non-votes will not affect whether the BHB adjournment proposal is approved.

Proxies submitted by mail must be received by the close of business on January 15, 2019. Proxies submitted by telephone or through the Internet must be received by 8:00 a.m., Eastern Time, on January 16, 2019.

Shares Held in Brokerage Accounts: If you hold your shares of BHB common stock in street name (that is, you hold your shares of BHB common stock through a broker, bank or other holder of record), your bank, broker or other holder of record will forward proxy materials and voting instructions that you must follow in order to vote your shares of BHB common stock. You may receive more than one proxy card if your shares of BHB common stock are registered in different names or are held in more than one account. A broker, bank or other holder of record will not be able to vote your shares at the BHB special meeting without first receiving instructions from you on how to vote.

Shares Held in the BHB 401(k) Plan: If you are a participant in the Blue Hills Bancorp, Inc. Stock Fund of the Blue Hills Bank 401(k) Retirement Plan (which we refer to as the BHB 401(k) Plan) and indirectly hold shares of BHB common stock through the BHB 401(k) Plan, you may vote any shares of BHB common

4

stock held in your BHB 401(k) Plan account as of the BHB record date ONLY by following the separate voting instructions provided by the BHB 401(k) Plan trustee. Your 401(k) vote authorization form must be received by 11:59 p.m., Eastern Time, on January 9, 2019. The telephonic and internet voting cutoff for providing your 401(k) vote authorization is 11:59 p.m., Eastern Time, on January 9, 2019. Blue Hills, as the BHB 401(k) Plan administrator, has instructed the BHB 401(k) Plan trustee to vote any shares in the BHB 401(k) Plan trustee for which participants have not issued timely voting instructions in the same proportion as the votes received on shares that participants have provided voting instructions.

Shares Held in the BHB ESOP Plan: If you are a participant in the BHB ESOP and indirectly hold shares of BHB common stock through the BHB ESOP, you may vote any shares of BHB common stock held in your BHB ESOP account as of the BHB record date ONLY by following the separate voting instructions provided by the BHB ESOP trustee. Your ESOP vote authorization form must be received by 11:59 p.m., Eastern Time, on January 9, 2019. The telephonic and internet voting cutoff for providing your ESOP vote authorization is 11:59 p.m., Eastern Time, on January 9, 2019. Under the terms of the BHB ESOP, the BHB ESOP trustee votes all shares held by the BHB ESOP, but each BHB ESOP participant may direct the trustee how to vote the shares of BHB common stock allocated to his or her account. The BHB ESOP trustee will vote all unallocated shares of BHB common stock held by the BHB ESOP and allocated shares for which no voting instructions are received in the same proportion as shares for which it has received timely voting instructions, so long as such vote is solely in the interests of participants and beneficiaries and in accordance with the requirements of the Employee Retirement Income Security Act of 1974, as amended.

A BHB stockholder executing a BHB proxy card may also revoke the proxy at any time before it is voted by giving written notice revoking the proxy to BHB’s Corporate Secretary, by timely filing another BHB proxy card bearing a later date or by attending the BHB special meeting and voting in person. Attending the BHB special meeting will not automatically revoke a BHB stockholder’s prior submission of a proxy (by Internet, telephone or in writing). All written notices of revocation or other communications with respect to revocation of proxies should be addressed to:

RISK FACTORS

In addition to the other information included in this proxy statement/prospectus, including the matters addressed under “Forward-Looking Statements,” BHB’s stockholders and Independent’s shareholders should carefully consider the following risks before deciding whether to vote for approval of the merger agreement. In addition, stockholders of BHB should read and consider the risks associated with the business of Independent because these risks will relate to the combined company. Certain of these risks with respect to the business of Independent can be found in Independent’s annual report on Form 10-K for the fiscal year ended December 31, 2017, and quarterly reports on Form 10-Q for each of the quarters ended March 31, 2018, June 30, 2018 and September 30, 2018, which reports are incorporated by reference into this joint proxy statement/prospectus. You should also consider the other information in this joint proxy statement/prospectus and the other documents incorporated by reference into this joint proxy statement/prospectus. See “Where You Can Find More Information” and “Incorporation of Certain Documents by Reference” beginning on page 122.

Risks Related to the Merger

Absent an exercise by BHB of its “walk away” right and a subsequent “top up” election by Independent, the exchange ratio used to determine the stock portion of the consideration in the merger will be 0.2308 and will not change due to changes in the market value of Independent common stock before the completion of the merger, regardless of how significant such changes might be.

Upon completion of the merger, each share of BHB common stock will be converted into the right to receive (i) $5.25 in cash and (2) 0.2308 of a share of Independent common stock. The exchange ratio used to determine the stock portion of the merger consideration will not increase based on fluctuations in the market price of Independent common stock regardless of how far the price of Independent common stock falls, except in the event Independent’s stock drops below certain levels and BHB exercises its “walk away” right and Independent subsequently exercises its right to “top up” the stock consideration to void the “walk away” right. The market value of Independent common stock has varied since Independent and BHB entered into the merger agreement and will continue to vary in the future due to changes in the business, operations or prospects of Independent, market assessments of the merger, regulatory considerations, market and economic considerations, and other factors both within and beyond the control of Independent. Therefore, at the time of the BHB special meeting, BHB’s stockholders will not know or be able to calculate the market value of the Independent common stock they will receive upon completion of the merger. For example, based on the range of closing prices of Independent common stock during the period from September 20, 2018, the last trading day before public announcement of the merger, through December 6, 2018, the last practicable date before the date of this document, the exchange ratio for the stock portion of the merger consideration plus the cash portion of the merger consideration represented a market value ranging from a low of $22.32 to a high of $26.01 for each share of BHB common stock exchanged for the merger consideration.

Because the market price of Independent common stock will fluctuate, BHB stockholders cannot be sure of the trading price of the stock portion of the merger consideration they will receive and the price of Independent common stock might decrease after the merger.

Upon completion of the merger, each share of BHB common stock will be converted into the right to receive merger consideration consisting of (i) $5.25 in cash and (2) 0.2308 of a share of Independent common stock. BHB does not have the right under the merger agreement to increase the exchange ratio in the merger agreement in the event of any decline in the stock price of Independent prior to the merger. There also will be a period of time between the date when BHB stockholders vote on the merger agreement and the date when the merger is completed. The market price of Independent common stock may vary between the date of this joint proxy statement/prospectus, the date of the BHB special meeting, and the date of completion of the merger. For example, during the twelve-month period ending on December 6, 2018 (the last practicable date before the date of this document), the closing price of Independent common stock varied from a low of $68.60 to a high of

19

$92.40 and ended that period at $74.72. The market value of Independent common stock fluctuates based upon general market economic conditions, Independent’s business and prospects and other factors. Many of these factors are beyond the control of Independent and are not necessarily related to a change in the financial performance or condition of Independent. As the market price for shares of Independent will fluctuate, based on numerous factors, the value of the shares of Independent common stock that a BHB stockholder will receive in the merger will correspondingly fluctuate. It is impossible to know the market price of Independent common stock after completion of the merger. Accordingly, the price of Independent common stock on the date of the BHB special meeting may not be indicative of the price of Independent common stock immediately prior to completion of the merger and the price of Independent common stock after the merger is completed. Independent’s common stock is listed on the Nasdaq Global Select Market under the symbol “INDB.” We urge BHB stockholders to obtain current market quotations for Independent common stock on a regular basis.

Independent intends to incur debt to fund cash payments required in connection with the merger.

Independent will be required to pay cash consideration in connection with the closing of the merger of up to approximately $171.7 million, not including transaction costs and expenses incurred by Independent in connection with the merger. Although the merger agreement does not include a financing contingency, Independent does not currently believe that it will have sufficient cash at closing at the holding company level to pay the cash portion of the merger consideration and other transaction costs and expenses required to complete the merger. Accordingly, Independent intends to issue debt in order to raise cash to complete the merger. If Independent is unable to issue debt on attractive terms or at all, Rockland Trust may have to pay a special dividend to Independent to supply Independent with the cash needed to complete the merger. However, any special dividend is subject to regulatory approval and the cash reserves and regulatory capital of Rockland Trust may be materially adversely affected by the special cash dividend. Independent has not entered into any definitive agreement for debt financing, and its ability to obtain debt financing is subject to various factors, including market conditions, Independent’s operating performance and financial condition and third party credit ratings. Independent cannot assure you that it will be able to secure debt financing in a sufficient amount, on acceptable terms, in a timely manner or at all, and Independent further cannot assure you that in the event it is unable to secure debt financing, Rockland Trust will receive regulatory approval to pay a special dividend to Independent.

The fairness opinions rendered to the boards of directors of BHB and Independent by the parties’ respective financial advisors prior to the signing of the merger agreement do not reflect changes in events or circumstances occurring after the respective dates of the opinions.

The opinions of KBW, financial advisor to BHB, and of Sandler, financial advisor to Independent, were delivered on and dated September 19, 2018 and September 20, 2018, respectively. Neither opinion reflects changes that may occur or may have occurred after the date on which it was delivered, including changes to the operations and prospects of BHB or Independent, changes in general market and economic conditions or other changes. Any of these changes may alter the relative value of BHB or Independent or the prices of shares of BHB common stock or Independent common stock by the time the merger is completed. The opinions do not speak as of the date the merger will be completed or as of any date other than the dates of the respective opinions, and neither BHB nor Independent expects to request updated fairness opinions from their respective financial advisors. For a description of the opinion of BHB’s financial advisor, please see “The Merger – Opinion of BHB’s Financial Advisor.” For a description of the opinion of Independent’s financial advisor, please see “The Merger – Opinion of Independent’s Financial Advisor.”

BHB will be subject to business uncertainties and contractual restrictions while the merger is pending.

Uncertainty about the effect of the merger on employees and customers may have an adverse effect on BHB and, consequently, on Independent. These uncertainties may impair BHB’s ability to attract, retain and motivate key personnel until the merger is consummated, and could cause customers and others that deal with BHB to

20

seek to change existing business relationships with BHB. Retention of certain employees may be challenging during the pendency of the merger, as certain employees may experience uncertainty about their future roles with Independent. If key employees depart because of issues relating to the uncertainty or difficulty of integration or a desire not to remain with Independent, Independent’s business following the merger could be harmed. In addition, the merger agreement restricts BHB from taking certain actions without the consent of Independent until the merger occurs. These restrictions may prevent BHB from pursuing attractive business opportunities that may arise prior to the completion of the merger. Please see the section entitled “The Merger Agreement – Conduct of Business Pending the Merger” of this joint proxy statement/prospectus for a description of the restrictive covenants to which BHB is subject.

Independent may fail to realize all of the anticipated benefits of the merger, particularly if the integration of Independent’s and BHB’s businesses is more difficult than expected.

The success of the merger will depend, in part, on our ability to successfully combine the businesses of Independent and BHB. Independent may fail to realize some or all of the anticipated benefits of the transaction if the integration process takes longer or is more costly than expected. Furthermore, any number of unanticipated adverse occurrences for either the business of BHB or Independent may cause us to fail to realize some or all of the expected benefits. The integration process could result in the loss of key employees, the disruption of each company’s ongoing businesses or inconsistencies in standards, controls, procedures and policies that adversely affect our ability to maintain relationships with clients, customers, depositors and employees or to achieve the anticipated benefits of the merger. Each of these issues might adversely affect Independent, BHB or both during the transition period, resulting in adverse effects on Independent following the merger. As a result, revenues may be lower than expected or costs may be higher than expected and the overall benefits of the merger may not be as great as anticipated.

Some of the directors and executive officers of BHB may have interests and arrangements that may have influenced their decisions to support and recommend that you approve the merger.

The interests of some of the directors and executive officers of BHB may be different from those of BHB stockholders, and certain directors and executive officers of BHB may be participants in arrangements that are different from, or are in addition to, those of BHB stockholders, including agreements in settlement of obligations to such officers under pre-existing employment and change in control agreements, employment agreements with Rockland Trust, and provisions in the merger agreement relating to indemnification of directors and officers and insurance for directors and officers of BHB for events occurring before the merger. These interests are described in more detail in the section of this joint proxy statement/prospectus entitled “The Merger – Interests of BHB’s Executive Officers and Directors in the Merger” beginning on page 81.

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

The merger agreement contains provisions that limit BHB’s ability to solicit, initiate, encourage or take any actions to facilitate competing third-party proposals to acquire all or substantially all of BHB. These provisions, which include a $26,200,000 termination fee and/or the reimbursement of up to $750,000 in Independent’s expenses, payable under certain circumstances, might discourage a potential competing acquiror that might have an interest in acquiring all or substantially all of BHB from considering or proposing that acquisition even if it were prepared to pay consideration with a higher per share market price than that proposed in the merger, or might result in a potential competing acquiror proposing to pay a lower per share price to acquire BHB than it might otherwise have proposed to pay.

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

Before the merger may be completed, certain approvals or consents must be obtained from the various bank regulatory and other authorities of the United States and the Commonwealth of Massachusetts. These

21

governmental entities, including the Federal Reserve Board, the FDIC and the Massachusetts Division of Banks, may impose conditions on the completion of the merger or require changes to the terms of the merger. While Independent and BHB do not currently expect that any such conditions or changes would be imposed, there can be no assurance that they will not be, and such conditions or changes could have the effect of delaying completion of the merger or imposing additional costs on or limiting the revenues of Independent following the merger, any of which might have a material adverse effect on Independent following the merger. Independent is not obligated to complete the merger if the regulatory approvals received in connection with the completion of the merger include any conditions or restrictions that would constitute a “Burdensome Condition” as defined in the merger agreement.

There can be no assurance as to whether the regulatory approvals will be received or the timing of the approvals. For more information, see the section entitled “The Merger – Regulatory Approvals Required to Complete the Merger” of this joint proxy statement/prospectus beginning on page 79.

If the merger is not consummated by July 31, 2019, either Independent or BHB may choose not to proceed with the merger.

Either Independent or BHB may terminate the merger agreement if the merger has not been completed by July 31, 2019, unless the failure of the merger to be completed has resulted from the failure of the party seeking to terminate the merger agreement to perform its obligations.

The shares of Independent common stock to be received by BHB stockholders as a result of the merger will have different rights from the shares of BHB common stock.

The rights associated with BHB common stock are different from the rights associated with Independent common stock. See the section of this joint proxy statement/prospectus entitled “Comparison of Rights of Shareholders of Independent and Stockholders of BHB” beginning on page 111 for a discussion of the different rights associated with Independent common stock.

Stockholders of BHB will have a reduced ownership and voting interest after the merger and will exercise less influence over management.

As a result of the merger, the percentage ownership of every BHB stockholder in the combined company will be smaller than the BHB stockholder’s percentage ownership of BHB prior to the merger. Independent estimates that upon completion of the merger, current BHB stockholders will own approximately 18% of the outstanding shares of Independent common stock, and current Independent shareholders will own approximately 82% of the outstanding shares of Independent common stock.

Failure to complete the merger could negatively impact the future business and financial results of BHB.

If the merger is not completed, the ongoing business of BHB may be adversely affected and BHB will be subject to several risks, including the following:

22

In addition, if the merger is not completed, BHB may experience negative reactions from its customers and employees. BHB also could be subject to litigation related to any failure to complete the merger or to enforcement proceedings commenced against BHB to perform its obligations under the merger agreement. If the merger is not completed, BHB cannot assure its stockholders that the risks described above will not materialize and will not materially affect the business and financial results of BHB.

BHB stockholders will not have dissenters’ rights in the merger.

Dissenters’ rights are statutory rights that, if applicable under law, enable stockholders 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 stockholders in connection with the extraordinary transaction. Under the Maryland General Corporation Law, a stockholder may not dissent from a merger as to shares that are listed on a national securities exchange at the record date fixed to determine the stockholders entitled to receive notice of the meeting of stockholders to vote upon the agreement of merger or consolidation.

Because BHB common stock is listed on the Nasdaq Global Select Market, a national securities exchange, and is expected to continue to be so listed on the record date, and because the merger otherwise satisfies the foregoing requirements of the Maryland General Corporation Law, holders of BHB common stock will not be entitled to dissenters’ rights in the merger with respect to their shares of BHB common stock.

Independent will be able to issue additional shares of its common stock in the future, which may adversely affect the market price of Independent common stock and dilute the holdings of existing shareholders.

In the future, Independent may issue additional shares of Independent common stock in connection with another acquisition, to increase its capital resources or if Independent’s or Rockland Trust’s capital ratios fall below or near the Basel III regulatory required minimums. Additional common stock offerings may dilute the holdings of Independent’s existing shareholders or reduce the market price of Independent common stock, or both. Independent may also issue shares of Independent preferred stock, which may be viewed as having adverse effects upon the holders of common stock.

Risks Related to Independent’s Business

Independent and Rockland Trust will have over $10 billion in total consolidated assets as a result of the merger, which will lead to increased regulation.

Upon consummation of the merger, and as of September 30, 2018 on a pro forma basis giving effect to the merger, Independent and Rockland Trust will each have approximately $11.5 billion in total consolidated assets. Accordingly, Independent and Rockland Trust will become subject to certain regulations that apply only to depository institution holding companies or depository institutions with total consolidated assets of $10 billion or more.

Debit card interchange fee restrictions set forth in Section 1075 of the Dodd-Frank Wall Street Reform and Consumer Protection Act, which is known as the Durbin Amendment, as implemented by regulations of the Federal Reserve Board, cap the maximum debit interchange fee that a debit card issuer may receive per transaction at the sum of $0.21 plus five basis points. A debit card issuer that adopts certain fraud prevention procedures may charge an additional $0.01 per transaction. Debit card issuers with total consolidated assets of less than $10 billion, which currently includes Rockland Trust and Blue Hills, are exempt from these interchange

23

fee restrictions. The exemption for small issuers ceases to apply as of July 1st of the year following the calendar year in which the debit card issuer has total consolidated assets of $10 billion or more at calendar year-end. As a result, if the bank merger is consummated in 2019, Rockland Trust will become subject to the interchange restrictions of the Durbin Amendment beginning July 1, 2020.

In addition, an insured depository institution with total assets of $10 billion or more is subject to supervision, examination, and enforcement with respect to consumer protection laws by the Consumer Financial Protection Bureau, which we refer to as the CFPB. Under its current policies, the CFPB will assert jurisdiction in the first quarter after the call reports of merging insured depository institutions, on a combined basis, show total consolidated assets of $10 billion or more for four consecutive quarters, including quarters ended prior to the merger. As a result, Independent expects Rockland Trust to become subject to CFPB supervision, examination and enforcement at the beginning of the quarter following consummation of the bank merger.

There are other regulatory requirements that apply to insured depository institution holding companies and insured depository institutions with total consolidated assets of $10 billion or more. These include, but are not limited to, (i) the establishment by publicly traded depository institution holding companies with $10 billion or more in assets of a risk committee responsible for oversight of enterprise-wide risk management practices that are commensurate with the entity’s structure, risk profile, complexity, activities and size and (ii) an institution with total consolidated assets of $10 billion or more no longer being entitled to benefit from the FDIC’s offset of the effect of the increase in the statutory minimum Deposit Insurance Fund reserve ratio to 1.35% from the former statutory minimum of 1.15% that is required for institutions with assets of less than $10 billion by the Dodd-Frank Wall Street Reform and Consumer Protection Act.

In addition, Congress and/or regulatory agencies may impose new requirements or surcharges on these institutions in the future. The Economic Growth, Regulatory Reform, and Consumer Protection Act, which was enacted on May 24, 2018, includes provisions that, as they are implemented, relieve banking organizations with total consolidated assets of less than $10 billion (and that satisfy certain other conditions) from risk-based capital requirements, restrictions on proprietary trading and investment and sponsorship in hedge funds and private equity funds known as the Volcker Rule, and certain other regulatory requirements. Once Independent and Rockland Trust have total consolidated assets of $10 billion or more, Independent and Rockland Trust will no longer qualify for any of the foregoing relief.

There can be no assurance that the benefits of the merger will outweigh the regulatory costs resulting from Independent and Rockland Trust having total consolidated assets of $10 billion or more.

You should read and consider other risk factors specific to Independent’s business that will also affect the combined company after the merger is consummated. These risks are described in the sections entitled “Risk Factors” in Independent’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017 and in other documents incorporated by reference into this joint proxy statement/prospectus. Please see the section entitled “Where You Can Find More Information” beginning on page 122 of this joint proxy statement/prospectus for the location of information incorporated by reference into this joint proxy statement/prospectus.

FORWARD-LOOKING STATEMENTS

This document contains or incorporates by reference forward-looking statements regarding the financial condition, results of operations, earnings outlook, and business prospects of Independent, BHB and the potential combined company and may include statements for the period following the completion of the merger. You can find many of these statements by looking for forward-looking terminology such as “should,” “expect,” “believe,” “view,” “opportunity,” “allow,” “continues,” “reflects,” “typically,” “usually,” “anticipate,” or similar statements or variations of such terms.

The forward-looking statements involve certain assumptions, risks, and uncertainties. In particular, the ability of either Independent or BHB to predict results or actual effects of its plans and strategies, or those of the combined company, is inherently uncertain. Accordingly, actual results may differ materially from those expressed in, or implied by, the forward-looking statements. You are therefore cautioned not to place undue reliance on these statements, which speak only as of the date of this document or the date of any document incorporated by reference in this document. Some of the factors that may cause actual results or earnings to differ materially from those contemplated by the forward-looking statements include, but are not limited to, those discussed elsewhere in this joint proxy statement/prospectus under “Risk Factors”, as well as the following:

25

All subsequent written and oral forward-looking statements concerning the merger or other matters addressed in this joint proxy statement/prospectus and attributable to Independent or BHB or any person acting on their behalf are expressly qualified in their entirety by the cautionary statements contained or referred to in this section. Except to the extent required by applicable law or regulation, Independent and BHB undertake no obligation to update these forward-looking statements to reflect events or circumstances after the date of this joint proxy statements/prospectus or to reflect the occurrence of unanticipated events.

SUMMARY HISTORICAL AND UNAUDITED PRO FORMA FINANCIAL INFORMATION

Comparative Per Share Market Price Information

Independent common stock and BHB common stock each trades on the Nasdaq Global Select Market under the symbols “INDB” and “BHBK,” respectively. The following presents the closing sale prices of Independent common stock and BHB common stock on September 20, 2018, the last trading day before we announced the merger agreement, and December 6, 2018, the last practicable trading day prior to mailing this document. The table also sets forth the equivalent value of the consideration to be paid in the merger per share of BHB common stock on those dates, calculated by adding $5.25 to the product obtained by multiplying the closing price of Independent common stock on those dates by an exchange ratio of 0.2308, which represents the fraction of a share of Independent common stock that BHB’s stockholders will receive in the merger for each share of BHB common stock.

The above table shows only historical comparisons. These comparisons may not provide meaningful information to BHB stockholders in determining whether to approve the merger agreement. The market prices of both Independent common stock and BHB common stock will fluctuate prior to the merger. BHB stockholders are urged to obtain current stock price quotations for Independent common stock and BHB common stock and to review carefully the other information contained in this joint proxy statement/prospectus or incorporated by reference into this joint proxy statement/prospectus in considering whether to approve the merger agreement. See the section entitled “Where You Can Find More Information” beginning on page 122 of this joint proxy statement/prospectus.

Comparative Stock Prices and Dividends

The following table sets forth, for the periods indicated, the high and low closing prices per share of Independent common stock as reported by the Nasdaq Global Select Market and the high and low closing prices per share of BHB common stock as reported by the Nasdaq Global Select Market. The table also provides information as to dividends declared per share of Independent common stock and BHB common stock. As of November 1, 2018, there were 27,551,581 shares of Independent common stock issued and outstanding and approximately 2,441 shareholders of record and 26,857,884 shares of BHB common stock issued and outstanding and approximately 730 stockholders of record.

After completion of the merger, the timing and amount of the payment of dividends, if any, will be at the discretion of Independent’s board of directors and will be determined after consideration of various factors, including level of earnings, cash requirements and financial condition.

BHB expects to continue to declare regular quarterly cash dividends on BHB common stock until the merger is completed, subject to the terms and conditions of the merger agreement, which prohibits BHB from declaring or paying any cash dividends other than regular quarterly cash dividends of no more than $0.20 per share of BHB common stock during the time period between the signing of the merger agreement and the closing

28

of the merger. Accordingly, special dividends consistent with 2018 and 2017 may not be paid by BHB without the prior consent of Independent and are not expected to be paid. Holders of BHB common stock will stop receiving cash dividends with respect to shares of BHB common stock upon completion of the merger, when the separate corporate existence of BHB will cease.

Independent Selected Historical Financial and Operating Data

The following table provides summary historical consolidated financial condition data for Independent as of the end of each of the fiscal years in the five-year period ended December 31, 2017, and operating and per share data and operating ratios for each of the corresponding fiscal years and as of the end of each of the nine months ended September 30, 2018 and September 30, 2017, and for the corresponding fiscal periods. The annual historical consolidated financial condition, operating and per share data and operating ratios have been derived in part from Independent’s audited financial statements and related notes incorporated by reference into this document. The historical consolidated financial condition, operating and per share data, and operating ratios as of the end of each of the nine months ended September 30, 2018 and September 30, 2017 and for the corresponding fiscal periods have been derived from Independent’s unaudited financial statements and related notes incorporated by reference into this document and are not necessarily indicative of the results that may be expected for the full year. The following information is only a summary and you should read it in conjunction with Independent’s financial statements and related notes incorporated by reference into this document.

BHB Selected Historical Consolidated Financial Data

The following table provides summary historical consolidated financial condition data for BHB as of the end of each of the fiscal years in the five-year period ended December 31, 2017, and operating and per share data and operating ratios for each of the corresponding fiscal years and as of the end of each of the nine months ended September 30, 2018 and September 30, 2017, and for the corresponding fiscal periods. The annual historical consolidated financial condition, operating and per share data and operating ratios have been derived in part from BHB’s audited financial statements and related notes incorporated by reference into this document. The historical consolidated financial condition, operating and per share data and operating ratios as of the end of each of the nine months ended September 30, 2018 and September 30, 2017, and for the corresponding fiscal periods, have been derived from BHB’s unaudited financial statements and related notes incorporated by reference into this document and are not necessarily indicative of the results that may be expected for the full year. The following information is only a summary and you should read it in conjunction with BHB’s financial statements and related notes incorporated by reference into this document.

PRO FORMA FINANCIAL DATA

The following unaudited pro forma condensed combined financial information is based on the historical financial statements of Independent and BHB and has been prepared to illustrate the financial effect of the merger of BHB with and into Independent. The following unaudited pro forma condensed combined financial information combines the historical consolidated financial position and results of operations of Independent and its subsidiaries and BHB and its subsidiaries, as an acquisition by Independent of BHB using the acquisition method of accounting and giving effect to the related pro forma adjustments described in the accompanying notes. Under the acquisition method of accounting, the assets and liabilities of BHB will be recorded by Independent at their respective fair values as of the date the merger is completed.

The unaudited pro forma condensed combined balance sheet gives effect to the transaction as if the transaction had occurred on September 30, 2018. The unaudited pro forma condensed combined income statements for the nine months ended September 30, 2018 and the year ended December 31, 2017 give effect to the transaction as if the transaction had become effective at January 1, 2017.

These unaudited pro forma condensed combined financial statements reflect the merger of BHB with and into Independent based upon estimated preliminary acquisition accounting adjustments. Actual adjustments will be made as of the effective date of the merger and, therefore, may differ from those reflected in the unaudited pro forma condensed combined financial information.

The unaudited pro forma condensed combined financial statements included in this joint proxy statement/prospectus are presented for informational purposes only and do not necessarily reflect the financial results of the combined company had the companies actually been combined at the beginning of each period presented. The adjustments included in these unaudited pro forma condensed financial statements are preliminary and may be revised. This information also does not reflect the benefits of the expected cost savings and expense efficiencies, opportunities to earn additional revenue, potential impacts of current market conditions on revenues or asset dispositions, among other factors, and includes various preliminary estimates and may not necessarily be indicative of the financial position or results of operations that would have occurred if the merger had been consummated on the date or at the beginning of the period indicated or which may be attained in the future. The unaudited pro forma combined condensed consolidated financial information has been derived from and should be read in conjunction with the historical consolidated financial statements and the related notes of Independent, which have been separately filed by Independent with the SEC and are incorporated by reference in this joint proxy statement/prospectus, and BHB, which have been separately filed by BHB with the SEC and are incorporated by reference in this joint proxy statement/prospectus.
