SUBJECT TO COMPLETION, DATED May 14, 2021

PRELIMINARY PROXY STATEMENT/PROSPECTUS

MERGER PROPOSED — YOUR VOTE IS VERY IMPORTANT

To the Shareholders of Legacy Bank of Florida:

On March 23, 2021, Seacoast Banking Corporation of Florida, or Seacoast, Seacoast National Bank, or SNB, and Legacy Bank of Florida, or Legacy, entered into an Agreement and Plan of Merger (which we refer to as the “merger agreement”) that provides for the combination of our two banks. Under the merger agreement, Legacy will merge with and into SNB, with SNB as the surviving bank (which we refer to as the “merger”). The acquisition will expand Seacoast’s presence in the attractive Broward and Palm Beach counties and strengthen its position in the state.

In the merger, each share of Legacy common stock (except for specified shares of Legacy common stock held by Legacy, Seacoast or SNB and any dissenting shares), will be converted into the right to receive 0.1703 (which we refer to as the “exchange ratio”) of a share of Seacoast common stock (which we refer to as the “merger consideration” and also in an aggregate consideration amount, which includes the substitute stock options certain Legacy shareholders may receive, as the “aggregate merger consideration”). However, in the event that Legacy’s consolidated tangible shareholders’ equity, as defined in the merger agreement, is less than Legacy’s target consolidated tangible shareholders’ equity (defined in the merger agreement as $58.2 million, less the impact of after-tax permitted expenses including (i) those reasonable expenses incurred in connection with the merger and (ii) the fee payable to Legacy’s financial advisor) and Legacy’s general allowance for loan and lease losses is less than 0.75% of total loans and leases outstanding (excluding loans originated under the Paycheck Protection Program (“PPP”)), then Seacoast shall have the option to adjust the merger consideration downward by an amount that is reflective of the overall shortfall between Legacy’s target consolidated tangible shareholders’ equity and Legacy’s consolidated tangible shareholders’ equity.

Because the exchange ratio is fixed, the market value of the merger consideration will fluctuate with the market price of Seacoast common stock and other factors and will not be known at the time Legacy shareholders vote on the merger agreement. Based on the closing price of Seacoast’s common stock on the NASDAQ Global Select Market on , 2021, the last practicable date before the date of this document, the value of the per share stock consideration payable to holders of Legacy common stock was approximately $ . We urge you to obtain current market quotations for Seacoast common stock (trading symbol “SBCF”) because the value of the per share stock consideration will fluctuate.

Based on the current number of shares of Legacy common stock outstanding, Seacoast expects to issue up to approximately million shares of common stock to the Legacy shareholders. Upon completion of the merger, current Legacy shareholders will own approximately 4.63% of the common stock of Seacoast immediately following the merger. However, any increase or decrease in the number of shares of Legacy common stock outstanding that occurs for any reason prior to the completion of the merger will cause the actual number of shares issued upon completion of the merger to change.

At the annual meeting of Legacy shareholders, holders of Legacy common stock will be asked to vote to elect three class III directors, to approve the merger agreement and related matters as described in this proxy statement/prospectus. Legacy shareholders will also be asked to approve the proposal to adjourn the annual meeting, if necessary or appropriate, to solicit additional proxies in favor of the merger agreement and related matters, as described in this proxy statement/prospectus.

The annual meeting of Legacy shareholders will be held on , 2021 at , , Boca Raton, Florida, at local time.

Legacy’s board of directors has unanimously determined that the merger agreement and the transactions contemplated by the merger agreement, including the merger, are advisable, fair to and in the best interests of Legacy and its shareholders, has authorized, adopted and approved the merger agreement, the merger and the transactions contemplated by the merger agreement and recommends that Legacy shareholders vote “FOR” the proposal to approve the merger agreement, “FOR” the election of the director nominees, and “FOR” the proposal to adjourn the Legacy annual meeting, if necessary or appropriate, to solicit additional proxies in favor of the proposal to approve the merger agreement.

TABLE OF CONTENTS

This document, which serves as a proxy statement for the annual meeting of Legacy shareholders and as a prospectus for the shares of Seacoast common stock to be issued in the merger to Legacy shareholders, describes the annual meeting of Legacy, the directors to be elected at the annual meeting, the merger, the documents related to the merger and other matters related to the merger and the annual meeting. Please carefully read this entire proxy statement/prospectus, including “Risk Factors,” beginning on page 17, for a discussion of the risks relating to the proposed merger. You also can obtain information about Seacoast from documents that Seacoast has filed with the Securities and Exchange Commission.

If you have any questions concerning the merger, Legacy shareholders should contact Dennis G. Bedley, 2300 Glades Road, Suite 120/140 West, Boca Raton, Florida 33431 (561) 544-8400.

We look forward to seeing you at the meeting.

QUESTIONS AND ANSWERS ABOUT THE MERGER AND THE ANNUAL MEETING

The following are answers to certain questions that you may have regarding the annual meeting and merger. The parties urge you to read carefully the remainder of this document because the information in this section may not provide all the information that might be important to you in determining how to vote. Additional important information is also contained in the appendices to, and the documents incorporated by reference in, this document. In this proxy statement/prospectus we refer to Seacoast Banking Corporation of Florida as “Seacoast,” Seacoast National Bank as “SNB” and Legacy Bank of Florida as “Legacy,” “we,” “us,” and “our.”

Why am I receiving this proxy statement/prospectus?

Our board of directors is soliciting proxies to be voted at the Legacy annual meeting. This proxy statement/prospectus summarizes the information that you need to know to vote by proxy or in person at the annual meeting.

Seacoast, SNB and Legacy have entered into an Agreement and Plan of Merger, dated as of March 23, 2021 (which we refer to as the “merger agreement”), pursuant to which Legacy will merge with and into Seacoast’s wholly owned bank subsidiary, SNB, with SNB continuing as the surviving bank and using the name “Seacoast National Bank” (the “merger”). A copy of the merger agreement is included in this proxy statement/prospectus as Appendix A.

The merger cannot be completed unless, among other things, the holders of at least two-thirds of the outstanding shares of Legacy common stock vote in favor of the proposal to approve the merger agreement.

Shareholders of Legacy are also being asked to elect three Class III directors to the Legacy board of directors for a three-year term. Legacy has nominated the following persons to serve as Class III directors: Dennis G. Bedley, Leo B. Berman, and Thomas M. McDonald.

In addition, Legacy is soliciting proxies from holders of Legacy common stock with respect to a proposal to adjourn the Legacy annual meeting, if necessary or appropriate, to solicit additional proxies in favor of the proposal to approve the merger agreement if there are insufficient votes at the time of such adjournment to approve such proposal.

This proxy statement/prospectus contains important information about the merger, the Class III director nominees, and the other proposals being voted on at the annual meeting, and you should read it carefully. It is a proxy statement because Legacy’s board of directors is soliciting proxies from its shareholders. It is a prospectus because Seacoast will issue shares of Seacoast common stock to holders of Legacy common stock in connection with the merger. The enclosed materials allow you to have your shares voted by proxy without attending the Legacy meeting. Your vote is important. We encourage you to submit your proxy as soon as possible.

Why do Seacoast and Legacy want to merge?

We believe the combination of Seacoast and Legacy will create one of the leading community banking franchises in the Broward/Palm Beach market, providing our customers with additional branch locations and our shareholders with improved market share. The Legacy board of directors has unanimously determined that the merger is advisable, fair to and in the best interests of Legacy and its shareholders and recommends that the Legacy shareholders vote “FOR” approval of the merger agreement. For more information about the reasons for the merger, see “The Merger — Seacoast’s Reasons for the Merger” and “The Merger — Legacy’s Reasons for the Merger and The Recommendation of the Legacy Board of Directors.”

What will I receive in the merger?

If the merger is completed, for each share of Legacy common stock that you hold (other than dissenters’ shares) immediately prior to the effective time of the merger, you will receive 0.1703, which we refer to as the exchange ratio, of a share of Seacoast common stock (which we refer to as the “merger consideration,” and also referred to in an aggregate consideration amount, which includes the substitute stock options certain Legacy shareholders may receive, as the “aggregate merger consideration”). If Legacy’s

TABLE OF CONTENTS

consolidated tangible shareholders’ equity, as defined in the merger agreement, is less than $58.2 million (less the after-tax impact of permitted expenses) and Legacy’s general allowance for loan and lease losses is less than 0.75% of total loans and leases outstanding (excluding loans originated under the Paycheck Protection Program (“PPP”)), Seacoast shall have the option to adjust the merger consideration downward by an amount that is reflective of the overall shortfall between $58.2 million (less the after-tax impact of permitted expenses) and Legacy’s consolidated tangible shareholders’ equity.

Seacoast will not issue any fractional shares of Seacoast common stock in the merger. Rather, Legacy shareholders who would otherwise be entitled to a fractional share of Seacoast common stock upon the completion of the merger will instead receive cash (without interest and rounded to the nearest whole cent) in an amount equal to such fractional part of a share of Seacoast common stock, rounded to the nearest one hundredth of a share, multiplied by the average of the daily volume weighted average price of Seacoast common stock on the NASDAQ Global Select Market for the twenty trading days ending on the trading day immediately prior to the determination date, which is defined as the later of the date on which the last required regulatory consent is obtained without regard to any requisite waiting period or the date on which the Legacy shareholder approval is obtained.

Will the value of the merger consideration change between the date of this proxy statement/prospectus and the time the merger is completed?

Yes, the value of the merger consideration will fluctuate between the date of this proxy statement/prospectus and the completion of the merger based upon the market value of Seacoast common stock and certain other adjustments. Any fluctuation in the market price of Seacoast common stock after the date of this proxy statement/prospectus will change the value of the shares of Seacoast common stock that Legacy shareholders will receive.

How will the merger impact Legacy equity awards?

Prior to the effective time of the merger, Legacy will take all actions necessary to accelerate the vesting of any outstanding Legacy options such that all unvested Legacy options shall be deemed vested immediately prior to the effective time of the merger. Legacy is also required to use commercially reasonable efforts to (a) amend the Legacy options to permit them to be exercised following a separation from service in accordance with the Legacy Bank of Florida Equity Incentive Plan, as amended, and (b) amend the Legacy options to allow for exercise of each option by payment of the exercise price through (i) delivery of cash or cash equivalents, (ii) delivery of previously-acquired shares of Legacy common stock, (iii) withholding of shares of Legacy common stock from the option based on the value of such shares on the date the option is exercised, (iv) broker-assisted market sales, or (v) any other “cashless exercise” arrangement.

Legacy has also agreed to take all actions necessary to cause each Legacy equity award issued and outstanding immediately prior to the effective time to be terminated at the effective time of the merger. In consideration of such termination, Seacoast will grant to each holder of Legacy options, as of the effective time, an option to purchase shares of Seacoast common stock pursuant to Seacoast’s Incentive Plan (which we refer to as the “substitute option”), on the same terms and conditions as applicable to each such Legacy option as in effect immediately prior to the effective time, except that (A) the number of shares of Seacoast common stock subject to such substitute option shall equal the product of (x) the number of shares of Legacy common stock subject to such Legacy option immediately prior to the effective Time, multiplied by (y) the exchange ratio, rounded down to the nearest whole share, and (B) the per share exercise price for the shares of Seacoast common stock issuable upon exercise of such substitute option shall equal the quotient determined by dividing (x) the exercise price per share of Legacy common stock at which such Legacy option was exercisable immediately prior to the effective time by (y) the exchange ratio, rounded up to the nearest whole cent. Each outstanding share of Seacoast common stock will remain outstanding and be unaffected by the merger. Legacy had a total of 2,128,754 stock options outstanding at March 23, 2021, of which 1,476,674 were vested and 652,080 were not vested.

TABLE OF CONTENTS

How does Legacy’s board of directors recommend that I vote at the annual meeting?

Legacy’s board of directors recommends that you vote “FOR” the proposal to approve the merger agreement, “FOR” the election of the three Class III director nominees, and “FOR” the adjournment proposal.

When and where is the annual meeting?

The Legacy annual meeting will be held at , Boca Raton, Florida, on , 2021 at local time.

Who can vote at the annual meeting of shareholders?

Holders of record of Legacy common stock at the close of business on , 2021, which is the date that the Legacy board of directors has fixed as the record date for the annual meeting, are entitled to vote at the annual meeting.

What will happen to Legacy following the merger?

Immediately following the effective time of the merger, Legacy will merge with and into SNB, with SNB being the surviving bank. Following the effective time of the merger, the separate corporate existence of Legacy will cease.

What do I need to do now?

After you have carefully read this proxy statement/prospectus and have decided how you wish to vote your shares, please vote your shares promptly so that your shares are represented and voted at the annual meeting. You must complete, sign, date and mail your proxy card in the enclosed postage-paid return envelope as soon as possible. If you hold your shares in your name as a shareholder of record, you must complete, sign, date and mail your proxy card in the enclosed postage-paid return envelope as soon as possible. If you hold your shares in “street name” through a bank, broker or other nominee, you must direct your bank, broker or other nominee how to vote in accordance with the instructions you have received from your bank, broker or other nominee. “Street name” shareholders who wish to vote in person at the annual meeting will need to obtain a proxy form from the institution that holds their shares.

What constitutes a quorum for the annual meeting?

The presence at the annual meeting, in person or by proxy, of holders of a majority of the outstanding shares of Legacy common stock will constitute a quorum for the transaction of business. Abstentions, if any, will be included in determining the number of shares present at the meeting for the purpose of determining the presence of a quorum.

What is the vote required to approve each proposal?

Approval of the merger agreement requires the affirmative vote of at least two-thirds of the outstanding shares of Legacy common stock entitled to vote on the merger agreement as of the close of business on , 2021, the record date for the annual meeting. If you (1) fail to submit a proxy or vote in person at the annual meeting, (2) mark “ABSTAIN” on your proxy, or (3) fail to instruct your bank, broker, or other nominee how to vote with respect to the proposal to approve the merger agreement, it will have the same effect as a vote “AGAINST” the merger agreement proposal and no effect on the election of directors or the adjournment proposal. Three Class III directors will be elected by a plurality of the votes cast for the election of the Class III directors, meaning that the nominees who receive the most affirmative votes, regardless of the actual number of votes for the director nominee, will be elected to serve as Class III directors on the Legacy board of directors. The adjournment proposal will be approved if the votes of Legacy common stock cast in favor of the adjournment proposal exceed the votes cast against the adjournment proposal.

Why is my vote important?

If you do not submit a proxy or vote in person, it may be more difficult for Legacy to obtain the necessary quorum to hold its annual meeting. In addition, your failure to submit a proxy or vote in person, or

TABLE OF CONTENTS

abstention will have the same effect as a vote against approval of the merger agreement. The merger agreement must be approved by the affirmative vote of the holders of at least two-thirds of the outstanding shares of Legacy common stock entitled to vote on the merger agreement. Legacy’s board of directors recommends that you vote “FOR” the proposal to approve the merger agreement, “FOR” the election of the three Class III director nominees, and “FOR” the adjournment proposal.

How many votes do I have?

You are entitled to one vote for each share of Legacy common stock that you owned as of the close of business on the record date. As of the close of business on the record date, shares of Legacy common stock were outstanding and entitled to vote at the Legacy annual meeting.

Do Legacy directors and executive officers have interests in the merger that are different from, or in addition to, my interests?

Yes. In considering the recommendation of Legacy’s board of directors with respect to the merger agreement, you should be aware that some of Legacy’s directors and executive officers have interests in the merger that are different from, or in addition to, the interests of Legacy’s shareholders generally. Interests of certain officers and directors that may be different from or in addition to the interests of Legacy’s shareholders include, but are not limited to, the receipt of continued indemnification and insurance coverage under the merger agreement, the receipt of Seacoast substitute stock options in exchange for Legacy option awards, acceleration of vesting of benefit awards, the payment of change in control payments to certain executives, and employment agreements between certain executives of Legacy and SNB.

If my shares are held in “street name” by my bank, broker or other nominee, will my bank, broker or other nominee automatically vote my shares for me?

TABLE OF CONTENTS

What are the U.S. federal income tax consequences of the merger to holders of Legacy common stock?

The merger is expected to qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended, which we refer to as the “Code.” Assuming the merger so qualifies, holders of Legacy common stock, except Legacy shareholders who exercise their dissenters’ rights, are not expected to recognize any gain or loss for U.S. federal income tax purposes on the shares of Seacoast common stock that they receive in the merger. However, Legacy shareholders may recognize gain or loss in connection with cash received in lieu of any fractional shares of Seacoast common stock they would otherwise be entitled to receive.

For further information, see “The Merger — Material U.S. Federal Income Tax Consequences of the Merger.”

The U.S. federal income tax consequences described above may not apply to all holders of Legacy stock. Your tax consequences will depend on your individual situation. Accordingly, we strongly urge you to consult your own tax advisor to determine the particular tax consequences of the merger to you.

Are Legacy shareholders entitled to dissenters’ rights?

Yes. Legacy shareholders are entitled to dissenters’ rights under Section 658.44 of the Florida Financial Institutions Code (the “FFIC”) and Sections 607.1301 through 607.1340 of the Florida Business Corporations Code (“FBCA”), a copy of which is attached as Appendix C to this proxy statement/prospectus. If you wish to assert dissenters’ rights, you (i) must vote “AGAINST” the Merger agreement proposal at the Legacy annual meeting or (ii) must deliver to Legacy, at or prior to the Legacy annual meeting, written notice of your intent to demand payment for your shares if the merger is consummated and you must not vote “FOR” approval of the merger agreement proposal. A summary of these procedures can be found under “The Merger — Dissenters Rights for Legacy Shareholders” beginning on page 48 and detailed information about the annual meeting can be found under “Information About the Annual Meeting” on page 27. Due to the complexity of the procedures for exercising dissenters’ rights, Legacy shareholders who are considering exercising such rights are encouraged to seek the advice of legal counsel. Failure to strictly comply with the applicable Florida law provisions will result in the loss of dissenters’ rights.

What should I do if I hold my shares of Legacy stock in book-entry form?

You are not required to take any specific actions if your shares of Legacy stock are held in book-entry form. After the completion of the merger, shares of Legacy stock held in book-entry form automatically will be exchanged for the merger consideration, including shares of Seacoast common stock in book-entry form and any cash to be paid in exchange for fractional shares in the merger, as applicable.

If I am a Legacy shareholder, should I send in my stock certificates now?

No. Please do not send in your Legacy stock certificates with your proxy. Seacoast’s transfer agent, Continental Stock Transfer and Trust Company, will send you instructions for exchanging Legacy stock certificates for the merger consideration. See “The Merger Agreement — Procedures for Converting Shares of Legacy Common Stock into Merger Consideration” beginning on page 9 of this proxy statement/prospectus.

Whom may I contact if I cannot locate my Legacy stock certificate(s)?

If you are unable to locate your original Legacy stock certificate(s), you should contact Dennis G. Bedley, 2300 Glades Road, Suite 120/140 West, Boca Raton, Florida, (561) 544-8400. Following the merger, any inquiries should be directed to Seacoast’s transfer agent, Continental Stock Transfer and Trust Company at 1 State Street, 30th Floor, New York, New York 10004, or at (212) 509-4000.

When do you expect to complete the merger?

Seacoast and Legacy expect to complete the merger in the third quarter of 2021. However, neither Seacoast nor Legacy can assure you when or if the merger will occur. Legacy must first obtain the approval of Legacy shareholders for the merger and Seacoast must receive the necessary regulatory approvals.

TABLE OF CONTENTS

What happens if I sell or transfer ownership of shares of Legacy common stock after the record date for the Legacy annual meeting?

The record date for the Legacy annual meeting is earlier than the expected date of completion of the merger. Therefore, if you sell or transfer ownership of your shares of Legacy common stock after the record date for the Legacy annual meeting, but prior to completion of the merger, you will retain the right to vote at the Legacy annual meeting, but the right to receive the merger consideration will transfer with the shares of Legacy common stock.

What happens if the merger is not completed?

If the merger is not completed, holders of Legacy common stock will not receive any consideration for their shares of Legacy common stock that otherwise would have been received in connection with the merger. Instead, Legacy will remain an independent bank. Under certain circumstances, if the merger is not completed due to a termination of the merger agreement, Legacy will be required to pay a termination fee to Seacoast. For more information about Legacy’s obligation to pay a termination fee see “The Merger Agreement — Termination Fee” beginning on page 67.

Regulatory Approvals

Completion of the merger is subject to various regulatory approvals, including approvals from the Office of the Comptroller of the Currency, or OCC. Notifications and/or applications requesting approvals for the merger may also be submitted to other federal and state regulatory authorities and self-regulatory organizations. The parties have filed notices and applications to obtain the necessary regulatory approvals of the OCC. The parties cannot be certain when or if they will obtain approval from the OCC or, if obtained, whether such approval will contain terms, conditions or restrictions not currently contemplated that will be detrimental to or have a material adverse effect on the combined company after the completion of the merger.

TABLE OF CONTENTS

The regulatory approvals to which the completion of the merger are subject are described in more detail under the section entitled “The Merger — Regulatory Approvals,” beginning on page of this proxy statement/prospectus.

The Merger (see page )

The terms and conditions of the merger are contained in the merger agreement, a copy of which is included as Appendix A to this proxy statement/prospectus and is incorporated by reference herein. You should read the merger agreement carefully and in its entirety, as it is the legal document governing the merger.

In the merger, Legacy will merge with and into SNB, with SNB as the surviving bank of such merger.

Closing and Effective Time of the Merger (see page )

The closing date is currently expected to occur in the third quarter of 2021. Simultaneously with the closing of the merger, Seacoast will file the articles of merger with the Florida Department of State. The merger will become effective on a mutually agreeable date following the date on which the satisfaction or waiver of the closing conditions have occurred. Neither Seacoast nor Legacy can predict, however, the actual date on which the merger will be completed because it is subject to factors beyond each company’s control, including whether or when the required regulatory approvals and Legacy’s shareholder approvals will be received.

Merger Consideration (see page )

Under the terms of the merger agreement, each share of Legacy common stock outstanding immediately prior to the effective time of the merger (excluding certain shares held by Seacoast, Legacy, SNB and their wholly-owned subsidiaries and dissenting shares described below) will be converted into the right to receive 0.1703, which we refer to as the exchange ratio, of a share of Seacoast common stock (which we refer to as the “merger consideration,” and also referred to in an aggregate consideration amount, which includes the substitute stock options certain Legacy shareholders may receive, as the “aggregate merger consideration”). Please see “The Merger Agreement — Consideration” for more information. If Legacy’s consolidated tangible shareholders’ equity, as defined in the merger agreement, is less than $58.2 million (less the after-tax impact of permitted expenses) and Legacy’s general allowance for loan and lease losses is less than 0.75% of total loans and leases outstanding (excluding loans originated under PPP), Seacoast shall have the option to adjust the merger consideration downward by an amount that is reflective of the overall shortfall between $58.2 million (less the after-tax impact of permitted expenses) and Legacy’s consolidated tangible shareholders’ equity.

For each fractional share that would otherwise be issued, Seacoast will pay cash (without interest and rounded to the nearest whole cent) in an amount equal to such fractional part of a share of Seacoast common stock, rounded to the nearest one hundredth of a share, multiplied by the average of the daily volume weighted average price of Seacoast common stock on the NASDAQ Global Select Market for the twenty (20) trading days ending on the trading day immediately prior to the determination date, which is defined as the later of the date on which the last required regulatory consent is obtained without regard to any requisite waiting period or the date on which the Legacy shareholder approval is obtained. No holder will be entitled to dividends, voting rights or any other rights as a shareholder in respect of any fractional share.

The value of the shares of Seacoast common stock to be issued in the merger will fluctuate between now and the closing date of the merger. Based on the closing price of Seacoast common stock on March 22, 2021, the last trading day before the signing of the merger agreement, the value of the merger consideration payable to holders of Legacy common stock was approximately $106.5 million, or $6.29 per share of common stock (which includes Legacy stock options). Based on the closing price of Seacoast common stock on ,2021, the last practicable date before the date of this document, the value of the merger consideration payable to holders of Legacy common stock was approximately $ . Legacy shareholders should obtain current sale prices for Seacoast common stock, which is traded on the NASDAQ Global Select Market under the symbol “SBCF.”

Equivalent Legacy Common Stock Per Share Value (see page )

Seacoast common stock trades on the NASDAQ Global Select Market under the symbol “SBCF.” Legacy common stock is not listed or traded on any established securities exchange or quotation system. Accordingly,

TABLE OF CONTENTS

there is no established public trading market for Legacy common stock. The following table presents the closing price of Seacoast common stock on March 22, 2021, the last trading date prior to the public announcement of the merger agreement, and , 2021, the last practicable trading day prior to the printing of this proxy statement/prospectus. The table also presents the equivalent value of the merger consideration per share of Legacy common stock on those dates, calculated by multiplying the closing sales price of Seacoast common stock on those dates by the exchange ratio of 0.1703.

Date	Seacoast closing sale price			Equivalent Legacy per share value
March 22, 2021		$	36.93		$	6.29
, 2021		$			$

The value of the shares of Seacoast common stock to be issued in the merger will fluctuate between now and the closing date of the merger. If Seacoast shares increase in value, so will the value of the merger consideration to be received by Legacy shareholders. Similarly, if Seacoast shares decline in value, so will the value of the merger consideration to be received by Legacy shareholders. Legacy shareholders should obtain current sale prices for Seacoast common stock.

Procedures for Converting Shares of Legacy Common Stock into Merger Consideration (see page )

No later than five business days after the effective time of the merger, Seacoast’s exchange agent, Continental Stock Transfer and Trust Company, will mail to each holder of record of Legacy common stock that is converted into the right to receive the merger consideration a letter of transmittal and instructions for the surrender of the holder’s Legacy stock certificate(s) for the merger consideration (including cash in lieu of any fractional Seacoast shares), and any dividends or distributions to which such holder is entitled to pursuant to the merger agreement.

Please do not send in your certificates until you receive these instructions.

Material U.S. Federal Income Tax Consequences of the Merger (see page )

The merger is expected to qualify as a reorganization within the meaning of Section 368(a) of the Code and the merger agreement will constitute a “plan of reorganization” as such term is used in Sections 354 and 361 of the Code. Assuming the merger so qualifies, holders of Legacy common stock are not expected to recognize any gain or loss for U.S. federal income tax purposes on the shares of Seacoast common stock they receive in the merger. However, Legacy shareholders may recognize gain or loss in connection with cash received in lieu of any fractional shares of Seacoast common stock they would otherwise be entitled to receive.

It is a condition to each of Seacoast’s and Legacy’s obligation to complete the merger that it receives a tax opinion from its respective legal counsel, dated the closing date of the merger, that the merger will be treated for U.S. federal income tax purposes as a reorganization within the meaning of Section 368(a) of the Code. These opinions, however, will not bind the Internal Revenue Service or the courts, which could take a contrary view. For further information, see “The Merger — Material U.S. Federal Income Tax Consequences of the Merger — Tax Consequences of the Merger Generally.”

Dissenters’ Rights (see page and Appendix C)

Under Florida law, Legacy shareholders have the right to dissent from the merger and receive whatever consideration may be determined to be due to such dissenting shareholder under Section 658.44 of the FFIC and Sections 607.1301 through 607.1340 of the FBCA instead of receiving the merger consideration. To exercise dissenters’ rights, Legacy shareholders must strictly follow the procedures established by Section 658.44 of the FFIC and Sections 607.1301 through 607.1340 of the FBCA, which include either voting “AGAINST” the merger agreement proposal at the Legacy annual meeting or delivering to Legacy at

TABLE OF CONTENTS

Opinion of Legacy’s Financial Advisor (see page and Appendix B)

In connection with the merger, Legacy’s financial advisor, Hovde Group (“Hovde”), delivered a written opinion, dated March 22, 2021, to the Legacy board of directors as to the fairness, from a financial point of view and as of the date of the opinion, to the holders of Legacy common stock of the exchange ratio in the proposed merger. The full text of the opinion, which describes the procedures followed, assumptions made, matters considered, and qualifications and limitations on the review undertaken by Hovde in preparing the opinion, is attached as Appendix B to this document. The opinion was for the information of, and was directed to, the Legacy board (in its capacity as such) in connection with its consideration of the financial terms of the merger. The opinion does not address the underlying business decision of Legacy to engage in the merger or enter into the merger agreement or constitute a recommendation to the Legacy board of directors in connection with the merger, and it does not constitute a recommendation to any holder of Legacy common stock or any shareholder of any other entity as to how to vote or act in connection with the merger or any other matter.

For further information, please see the section entitled “The Merger — Opinion of Legacy’s Financial Advisor” beginning on page .

Recommendation of the Legacy Board of Directors (see page )

Each of the directors of Legacy, who as of the date of the merger agreement held shares of Legacy common stock, certain executive officers of Legacy and certain beneficial holders of 5% or more of Legacy’s outstanding shares of common stock have entered into a shareholder support agreement with Seacoast pursuant to which each has agreed to vote “FOR” the approval of the merger agreement and the transactions contemplated thereby, subject to the terms of the shareholder support agreement.

Interests of Legacy Directors and Executive Officers in the Merger (see page )

In considering the recommendation of Legacy’s board of directors with respect to the merger agreement, you should be aware that some of Legacy’s directors and executive officers have interests in the merger that are different from, or in addition to, the interests of Legacy’s shareholders generally, including:

•

Certain Legacy executives are entitled to certain payments upon a change of control of Legacy.

TABLE OF CONTENTS

Treatment of Legacy Equity Awards (see page )

The merger agreement requires Legacy to take all actions necessary to accelerate the vesting of any outstanding Legacy options such that all unvested Legacy options shall be deemed vested immediately prior to the effective time of the merger. Legacy is also required to use commercially reasonable efforts to (a) amend the Legacy options to permit them to be exercised following a separation from service in accordance with the Legacy Bank of Florida Equity Incentive Plan, as amended, and (b) amend the Legacy options to allow for exercise of each option by payment of the exercise price through (i) delivery of cash or cash equivalents, (ii) delivery of previously-acquired shares of Legacy common stock, (iii) withholding of shares of Legacy common stock from the option based on the value of such shares on the date the option is exercised, (iv) broker-assisted market sales, or (v) any other “cashless exercise” arrangement.

The merger agreement further requires Legacy to take all actions necessary to cause each Legacy equity award issued and outstanding immediately prior to the effective time to be terminated at the effective time of the merger. In consideration of such termination, Seacoast will grant to each holder of Legacy options, as of the effective time, an option to purchase shares of Seacoast common stock pursuant to Seacoast’s Incentive Plan (which we refer to as the “substitute option”), on the same terms and conditions as applicable to each such Legacy option as in effect immediately prior to the effective time, except that (A) the number of shares of Seacoast common stock subject to such substitute option shall equal the product of (x) the number of shares of Legacy common stock subject to such Legacy option immediately prior to the effective time, multiplied by (y) the exchange ratio, rounded down to the nearest whole share, and (B) the per share exercise price for the shares of Seacoast common stock issuable upon exercise of such substitute option shall equal the quotient determined by dividing (x) the exercise price per share of Legacy common stock at which such Legacy option was exercisable immediately prior to the effective time by (y) the exchange ratio, rounded up to the nearest whole cent.

This means that the nominee who receives the most affirmative votes, regardless of the actual number of votes for the director nominee, will be elected to serve on the Legacy board of directors as a Class III director.

The adjournment proposal will be approved if the number of votes cast in favor of the adjournment proposal exceeds the number of votes cast opposing the adjournment proposal.

No Restrictions on Resale

All shares of Seacoast common stock received by Legacy shareholders in the merger will be freely tradable, except that shares of Seacoast received by persons who are or become affiliates of Seacoast for purposes of Rule 144 under the Securities Act may be resold by them only in transactions permitted by Rule 144, or as otherwise permitted under the Securities Act.

Dividends from SNB are Seacoast’s primary source of funds to pay dividends on its common stock. Under the National Bank Act, national banks may in any calendar year, without the approval of the OCC, pay dividends to the extent of net profits for that year, plus retained net profits for the preceding two years (less any required transfers to surplus). The need to maintain adequate capital in SNB also limits dividends that may be paid to Seacoast. On April 20, 2021, Seacoast’s board of directors approved a cash dividend of $0.13 per share. The dividend will be paid on June 30, 2021 to all shareholders of record as of the close of business on June 15, 2021.

Any further dividends paid on Seacoast’s common stock will be declared and paid at the discretion of its board of directors and would be dependent upon Seacoast’s liquidity, financial condition, results of operations, capital requirements and such other factors as the board of directors may deem relevant.

As of March 31, 2021, there were 15,772,897 shares of Legacy common stock, $1.00 par value per share, outstanding, which were held by approximately 460 holders of record.

Legacy common stock is not listed or traded on any established securities exchange or quotation system. Accordingly, there is no established public trading market for the Legacy common stock. Management is not aware of any trades in Legacy’s common stock since [•]. Legacy has never paid any cash dividends on the shares of Legacy.

Comparison of Shareholders’ Rights (see page )

For more information, please see the section entitled “Comparison of Shareholders’ Rights” beginning on page .

Risk Factors (see page )

Before voting at the Legacy annual meeting, you should carefully consider all of the information contained or incorporated by reference into this proxy statement/prospectus, including the risk factors set forth in the section entitled “Risk Factors” beginning on page or described in Seacoast’s reports filed with the SEC, which are incorporated by reference into this proxy statement/prospectus. Please see “Documents Incorporated by Reference” beginning on page .

TABLE OF CONTENTS

RISK FACTORS

An investment in Seacoast common stock in connection with the merger involves risks. Seacoast describes below the material risks and uncertainties that it believes affect its business and an investment in Seacoast common stock. In addition to the other information contained in, or incorporated by reference into, this proxy statement/prospectus, including Seacoast’s Annual Report on Form 10-K for the fiscal year ended December 31, 2020 and Seacoast’s Quarterly Report on Form 10-Q for the three months ended March 31, 2021, and the matters addressed under “Forward-Looking Statements,” you should carefully read and consider all of the risks and all other information contained in this proxy statement/prospectus in deciding whether to vote to approve the merger agreement. Additional Risk Factors included in Item 1A in Seacoast’s Annual Report on Form 10-K for the fiscal year ended December 31, 2020 and Seacoast’s Quarterly Report on Form 10-Q for the three months ended March 31, 2021 are incorporated herein by reference. You should read and consider those Risk Factors in addition to the Risk Factors listed below. If any of the risks described in this proxy statement/prospectus occur, Seacoast’s financial condition, results of operations and cash flows could be materially and adversely affected. If this were to happen, the value of the Seacoast common stock could decline significantly, and you could lose all or part of your investment.

The market price of Seacoast common stock after the merger may be affected by factors different from those currently affecting Legacy or Seacoast.

The businesses of Seacoast and Legacy differ in some respects and, accordingly, the results of operations of the combined company and the market price of Seacoast’s shares of common stock after the merger may be affected by factors different from those currently affecting the independent results of operations of each of Seacoast and Legacy. For a discussion of the business of Seacoast and of certain factors to consider in connection with that business, see the documents incorporated by reference into this proxy statement/prospectus and referred to under “Documents Incorporated by Reference.”

Because the sale price of Seacoast common stock will fluctuate, you cannot be sure of the value of the per share stock consideration that you will receive in the merger until the closing.

Under the terms of the merger agreement, each share of Legacy common stock outstanding immediately prior to the effective time of the merger (excluding shares of Legacy common stock owned by Legacy, Seacoast or SNB or the dissenting shares) will be converted into the right to receive 0.1703 shares of Seacoast common stock (plus cash in lieu of fractional shares), which is subject to adjustment based on the value of Legacy’s consolidated tangible shareholder’s equity and Legacy’s general allowance for loan and lease losses. The value of the shares of Seacoast common stock to be issued to Legacy shareholders in the merger will fluctuate between now and the closing date of the merger due to a variety of factors, including general market and economic conditions, changes in the parties’ respective businesses, operations and prospects and regulatory considerations, among other things. Many of these factors are beyond the control of Seacoast and Legacy. We make no assurances as to whether or when the merger will be completed. Legacy shareholders should obtain current sale prices for shares of Seacoast common stock before voting their shares of Legacy common stock at the annual meeting.

The merger will not be completed unless important conditions are satisfied or waived, including approval by Legacy shareholders.

Specified conditions set forth in the merger agreement must be satisfied or waived to complete the merger. If the conditions are not satisfied or waived, to the extent permitted by law or stock exchange rules, the merger will not occur or will be delayed and each of Seacoast and Legacy may lose some or all of the intended benefits of the merger. The following conditions, in addition to other closing conditions, must be satisfied or waived, if permissible, before Seacoast and Legacy are obligated to complete the merger:

•

The merger agreement and the transactions contemplated thereby must have been approved by the affirmative vote of at least two-thirds of the outstanding shares of Legacy common stock;

•

All regulatory consents required to consummate the transactions contemplated by the merger agreement must have been obtained and all waiting periods required by law must have expired and such

TABLE OF CONTENTS

consents must not be subject to any condition or consequence that would have a material adverse effect on Seacoast or any of its subsidiaries, including Legacy, after the effective time of the merger;

•

No order issued by any governmental authority preventing the consummation of the merger shall be in effect and no law or order shall have been enacted, entered, promulgated or enforced by any governmental authority that prohibits, restrains or makes illegal the consummation of the merger;

•

The registration statement (of which this proxy statement/prospectus is a part) registering shares of Seacoast common stock to be issued in the merger must have been declared effective, no stop order may have been issued by the SEC and no action, suit, proceeding or investigation by the SEC to suspend the effectiveness of the registration statement shall have been initiated and continuing;

•

The holders of no more than 5% of Legacy common stock shall have taken the actions required by the FFIC to qualify their common stock as dissenting shares;

•

Since the date of the merger agreement, no fact, circumstance or event shall have occurred that has had or is reasonably likely to have a material adverse effect on either party;

•

Certain Legacy employees shall have entered into claims letters and/or restrictive covenant agreements;

•

Legacy’s consolidated tangible shareholders’ equity as of the close of business on the 5th business day prior to the closing date shall not be less than $58.2 million and its general allowance for loan and lease losses shall not be less than 0.75% of total loans and leases outstanding (excluding PPP loans);

•

All outstanding Legacy equity awards shall have been terminated and cashed out and Legacy’s board of directors and shareholders shall have taken all action necessary to terminate the Legacy stock plans;

•

Each party shall have received from its tax counsel a U.S. federal income tax opinion that the merger qualifies as a “reorganization” within the meaning of Section 368(a) of the Code; and

•

The shares of Seacoast common stock to be issued pursuant to the merger shall have been approved for listing on the NASDAQ.

For a more detailed description of the conditions set forth in the merger agreement that must be satisfied or waived to complete the merger, see “The Merger Agreement — Conditions to Completion of the Merger” beginning on page .

Shares of Seacoast common stock to be received by holders of Legacy common stock as a result of the merger will have rights different from the shares of Legacy common stock.

Upon completion of the merger, the rights of former Legacy shareholders will be governed by the articles of incorporation, as amended, and bylaws of Seacoast. The rights associated with Legacy common stock are different from the rights associated with Seacoast common stock, although both companies are organized under Florida law. See “Comparison of Shareholders’ Rights” beginning on page for a discussion of the different rights associated with Seacoast common stock.

Legacy shareholders will have a reduced ownership and voting interest after the merger and will exercise less influence over management.

Legacy shareholders currently have the right to vote in the election of the board of directors of Legacy and on other matters affecting Legacy. Upon the completion of the merger, Legacy’s shareholders will be shareholders of Seacoast with a percentage ownership of Seacoast that is smaller than such shareholders’ current percentage ownership of Legacy. It is currently expected that the former shareholders of Legacy as a group will receive shares in the merger constituting approximately 4.63% of the outstanding shares of the combined company’s common stock immediately after the merger. Because of this, Legacy shareholders will have less influence on the management and policies of the combined company than they now have on the management and policies of Legacy.

If a Legacy shareholder exercises statutory dissenters’ rights, the value such shareholder receives could be less than the value of the merger consideration such shareholder would otherwise receive pursuant to the merger agreement.

Pursuant to Section 658.44 of the FFIC and Sections 607.1301 through 607.1340 of the FBCA, a Legacy shareholder who perfects dissenters’ rights as provided in such section is entitled to receive payment in cash of

TABLE OF CONTENTS

the value of each share of Legacy common stock held by such shareholder. The value of the share of Legacy common stock, as determined in accordance with the Florida statutes, may be less than the value of a share of the Legacy common stock such shareholder would otherwise receive pursuant to the merger agreement. See “The Merger — Dissenters’ Rights for Legacy Shareholders.”

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

Uncertainty about the effect of the merger on employees, customers, suppliers and vendors may have an adverse effect on the business, financial condition and results of operations of Legacy and Seacoast. These uncertainties may impair Seacoast’s or Legacy’s ability to attract, retain and motivate key personnel, depositors and borrowers pending the consummation of the merger, as such personnel, depositors and borrowers may experience uncertainty about their future roles following the consummation of the merger. Additionally, these uncertainties could cause customers (including depositors and borrowers), suppliers, vendors and others who deal with Seacoast or Legacy to seek to change existing business relationships with Seacoast or Legacy or fail to extend an existing relationship. In addition, competitors may target each party’s existing customers by highlighting potential uncertainties and integration difficulties that may result from the merger.

Seacoast and Legacy have a small number of key personnel. The pursuit of the merger and the preparation for the integration may place a burden on each company’s management and internal resources. Any significant diversion of management attention away from ongoing business concerns and any difficulties encountered in the transition and integration process could have a material adverse effect on each company’s business, financial condition and results of operations.

In addition, the merger agreement restricts Legacy from taking certain actions without Seacoast’s consent while the merger is pending. These restrictions may, among other matters, prevent Legacy from pursuing otherwise attractive business opportunities, selling assets, incurring indebtedness, engaging in significant capital expenditures in excess of certain limits set forth in the merger agreement, entering into other transactions or making other changes to Legacy’s business prior to consummation of the merger or termination of the merger agreement. These restrictions could have a material adverse effect on Legacy’s business, financial condition and results of operations. Please see the section entitled “The Merger Agreement — Conduct of Business Pending the Merger” beginning on page for a description of the covenants applicable to Legacy and Seacoast.

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

Although Seacoast estimates that it will realize cost savings from the merger when fully phased in, it is possible that the estimates of the potential cost savings could turn out to be incorrect. Unanticipated growth in Seacoast’s business may require Seacoast to continue to operate or maintain some facilities or support functions that are currently expected to be combined or reduced. The cost savings estimates also depend on Seacoast’s ability to combine the businesses of Seacoast and Legacy in a manner that permits those costs savings to be realized. If the estimates turn out to be incorrect or Seacoast is not able to combine the two companies successfully, the anticipated cost savings may not be fully realized or realized at all, or may take longer to realize than expected.

The combined company expects to incur substantial expenses related to the merger.

The combined company expects to incur substantial expenses in connection with completing the merger and combining the business, operations, networks, systems, technologies, policies and procedures of Seacoast and Legacy. Although Seacoast and Legacy have assumed that a certain level of transaction and combination expenses would be incurred, there are a number of factors beyond their control that could affect the total amount or the timing of their combination expenses. Many of the expenses that will be incurred, by their nature, are difficult to estimate accurately at the present time. Due to these factors, the transaction and combination expenses associated with the merger could, particularly in the near term, exceed the savings that the combined company expects to achieve from the elimination of duplicative expenses and the realization of economies of scale and cost savings related to the combination of the businesses following the completion of the merger. In addition, prior to completion of the merger, each of Legacy and Seacoast will incur or have incurred substantial expenses in connection with the negotiation and completion of the transactions

TABLE OF CONTENTS

contemplated by the merger agreement. If the merger is not completed, Seacoast and Legacy would have to recognize these expenses without realizing the anticipated benefits of the merger.

Seacoast and Legacy may waive one or more of the conditions to the merger.

Prior to or at the effective time of the merger, either party has the right to waive any default in the performance of any term of the merger agreement by the other party, to waive or extend the time for the compliance or fulfillment by the other party of any and all of such other party’s obligations under the merger agreement, and to waive any or all of the conditions to its obligations under the merger agreement.

The merger is expected to qualify as a “reorganization” within the meaning of Section 368(a) of the Code.

It is expected that the merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code. The obligation of Seacoast to complete the merger is conditioned upon the receipt of a U.S. federal income tax opinion to that effect from Seacoast’s tax counsel and the obligation of Legacy to complete the merger is conditioned upon the receipt of a U.S. federal income tax opinion to that effect from Legacy’s tax counsel. These tax opinions represent the legal judgment of counsel rendering the opinion and is not binding on the Internal Revenue Service or the courts. If the merger does not qualify as a tax-free reorganization, then the holders of shares of Legacy common stock will recognize gain in the amount equal to the difference between (i) the fair market value of the Seacoast common stock and cash consideration received as a result of the merger and (ii) the shareholder’s adjusted tax basis in the Legacy common stock surrendered in exchange therefor. The consequences of the merger to any particular Legacy shareholder will depend on that shareholder’s individual situation. We strongly urge you to consult your own tax advisor to determine the particular tax consequences of the merger to you.

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

Before the transactions contemplated by the merger agreement, including the merger, may be completed, various approvals must be obtained from bank regulatory authorities. These governmental entities may impose conditions on the granting of such approvals. Such conditions or changes and the process of obtaining regulatory approvals could have the effect of delaying completion of the merger or of imposing additional costs or limitations on Seacoast following the merger. The regulatory approvals may not be received at all, may not be received in a timely fashion, and may contain conditions on the completion of the merger that are not anticipated or have a material adverse effect. If the consummation of the merger is delayed, including by a delay in receipt of necessary governmental approvals, the business, financial condition and results of operations of each company may also be materially adversely affected.

The opinion of Legacy’s financial advisor delivered to Legacy’s board of directors prior to the signing of the merger agreement does not reflect any changes in circumstances since the date of the opinion.

Legacy’s board of directors received the opinion of Legacy’s financial advisor regarding the fairness, from a financial point of view, to the holders of Legacy’s common stock, of the exchange ratio on March 22, 2021. Subsequent changes in the operation and prospects of Seacoast or Legacy, general market and economic conditions and other factors that may be beyond the control of Seacoast or Legacy, and may significantly alter the value of Seacoast or the price of the shares of Seacoast common stock by the time the merger is completed. The opinion does not address the fairness of the exchange ratio from a financial point of view at the time the merger is completed, or as of any other date other than the date of such opinion. For a description of the opinion of Legacy’s financial advisor, please refer to the section entitled “The Merger — Opinion of Legacy’s Financial Advisor” beginning on page .

Legacy’s executive officers and directors have financial interests in the merger that are different from, or in addition to, the interests of Legacy shareholders.

Executive officers of Legacy and the Chairman of the board of directors of Legacy negotiated the terms of the merger agreement with Seacoast, and the Legacy board of directors approved and recommended that Legacy shareholders vote to approve the merger agreement. In considering these facts and the other information contained in this proxy statement/prospectus, you should be aware that certain Legacy executive

TABLE OF CONTENTS

officers and directors have financial interests in the merger that are different from, or in addition to, the interests of Legacy shareholders generally. See “The Merger — Interests of Legacy Directors and Executive Officers in the Merger” on page for information about these financial interests.

The termination fees and the restrictions on third party acquisition proposals set forth in the merger agreement may discourage others from trying to acquire Legacy.

Until the completion of the merger, with some limited exceptions, Legacy and its directors, officers, employees, representatives and affiliates are prohibited from initiating, soliciting, encouraging or knowingly facilitating any inquiry or proposal relating to any acquisition proposal, from engaging or participating in any negotiations concerning or with any person relating to any acquisition proposal or providing any confidential or nonpublic information or data to any person relating to an acquisition proposal. In addition, Legacy has agreed to pay to Seacoast in certain circumstances a termination fee equal to $4,600,000. These provisions could discourage other companies from trying to acquire Legacy even though those other companies might be willing to offer greater value to Legacy shareholders than Seacoast has offered in the merger. The payment of any termination fee could also have an adverse effect on Legacy’s financial condition. See “The Merger Agreement — Third Party Proposals” beginning on page and “The Merger Agreement — Termination Fee” beginning on page .

Failure of the merger to be completed, the termination of the merger agreement or a significant delay in the consummation of the merger could negatively impact Seacoast and Legacy.

If the merger is not consummated, the ongoing business, financial condition and results of operations of each party may be materially adversely affected and the market price of each party’s common stock may decline significantly, particularly to the extent that the current market price reflects a market assumption that the merger will be consummated. If the consummation of the merger is delayed, the business, financial condition and results of operations of each company may be materially adversely affected. If the merger agreement is terminated and a party’s board of directors seeks another merger or business combination, such party’s shareholders cannot be certain that such party will be able to find a party willing to engage in a transaction on more attractive terms than the merger.

If the merger is not completed, Seacoast and Legacy will have incurred substantial expenses without realizing the expected benefits of the merger.

Each of Seacoast and Legacy has incurred and will incur substantial expenses in connection with the negotiation and completion of the transactions contemplated by the merger agreement, as well as the costs and expenses of filing, printing, and mailing this proxy statements/prospectus, and all filing and other fees paid to the SEC in connection with the merger. If the merger is not completed, Seacoast and Legacy would have to recognize these expenses without realizing the expected benefits of the merger.

Some of the performing loans in the Legacy loan portfolio being acquired by Seacoast may be under-collateralized, which could affect Seacoast’s ability to collect all of the loan amount due.

In an acquisition transaction, the purchasing financial institution may be acquiring under-collateralized loans from the seller. Under-collateralized loans are risks that are inherent in any acquisition transaction and are mitigated through the loan due diligence process that the purchaser performs and the estimated fair market value adjustment that the purchaser places on the seller’s loan portfolio. When it acquires a loan portfolio, Seacoast will establish an allowance for credit losses to recognize the full amount of expected credit losses over the life of the acquired loans. With respect to the Legacy loan portfolio, Seacoast has preliminarily estimated a $10.8 million allowance for credit losses which Seacoast believes is adequate to mitigate the risk of under-collateralized, non- performing loans. There is no assurance that the allowance for credit losses that Seacoast will place on the Legacy loan portfolio to mitigate against under-collateralized, non-performing loans will be adequate or that Seacoast will not incur losses that could be greater than this estimate.

Recommendation of the Legacy Board of Directors

The Legacy board of directors recommends that Legacy shareholders vote “FOR” the merger proposal, “FOR” the election of Dennis G. Bedley, Leo B. Berman, and Thomas M. McDonald as Class III directors of Legacy, and “FOR” the adjournment proposal. See “The Merger — Legacy’s Reasons for the Merger and Recommendations of the Legacy Board of Directors” and “Election of Directors.”

Record Date and Quorum

, 2021 has been fixed as the record date for the determination of Legacy shareholders entitled to notice of, and to vote at, the annual meeting and any adjournment or postponement thereof. At the close of business on the record date, there were [•] shares of Legacy common stock outstanding and entitled to vote at the annual meeting, held by approximately [•] holders of record.

A quorum is necessary to transact business at the annual meeting. The presence, in person or by proxy, of the holders of a majority of the outstanding shares of Legacy common stock entitled to vote at the meeting is necessary to constitute a quorum. Shares of Legacy common stock represented at the annual meeting but not voted, including shares that a shareholder abstains from voting, will be counted for purposes of establishing a quorum. Once a share of Legacy common stock is represented at the annual meeting, it will be counted for the purpose of determining a quorum not only at the annual meeting but also at any adjournment or postponement of the annual meeting. In the event that a quorum is not present at the annual meeting, it is expected that the annual meeting will be adjourned or postponed.

TABLE OF CONTENTS

Required Vote

The affirmative vote of at least two-thirds of the outstanding shares of Legacy common stock must vote in favor of the proposal to approve the merger agreement. If you vote to “ABSTAIN” with respect to the merger proposal or if you fail to vote on the merger proposal, this will have the same effect as voting “AGAINST” the merger proposal.

The Class III directors will be elected by a plurality of the votes cast. As a result, the nominees who receive the most affirmative votes, regardless of the actual number of votes for the director nominee, will be elected to serve on the Legacy board of directors for a three-year term. If you vote to “ABSTAIN” with respect to the election of Class III directors or if you fail to vote for any director nominee, this will have no effect on the outcome of the election of the Class III directors.

The adjournment proposal will be approved if the votes of Legacy common stock cast in favor of the adjournment proposal exceed the votes cast against the adjournment proposal. If you vote to “ABSTAIN” with respect to the adjournment proposal or if you fail to vote on the adjournment proposal, this will have no effect on the outcome of the vote on the adjournment proposal.

Each share of Legacy common stock you own as of the record date for the annual meeting entitles you to one vote at the annual meeting on all matters properly presented at the meeting.

How to Vote — Shareholders of Record

PROPOSAL 1: THE MERGER

Background of the Merger

Over the past several years, as a part of its ongoing consideration and evaluation of long-term prospects and strategies, the Legacy board of directors and senior management have regularly assessed strategic alternatives for maximizing shareholder value, including as to growth opportunities and operational efficiencies with the objective to enhance profitability and prospects. The strategic discussions have focused on, among other things, the business environment facing financial institutions generally and Legacy, in particular, as well as conditions and ongoing consolidation in the financial services industry. In contemplating its strategic objectives, the board of directors of Legacy found it important to consider potential merger opportunities to maximize shareholder value while at the same time continuing to provide quality products and services to its local communities and customers.

Legacy engaged Hovde on January 30, 2019 to explore strategic alternatives. Throughout 2019 and 2020, a Hovde representative continued to provide management of Legacy with periodic updates on market conditions, the merger and acquisition landscape, valuations, buyers, and the financial institutions sales process and other information and continued to discuss the interest of Legacy in exploring strategic combinations in the best interests of Legacy and its shareholders.

In January 2020, Seacoast was approached by Hovde regarding its interest in a potential merger with Legacy. In February 2020, Seacoast signed a non-disclosure agreement with Legacy.

In February 2020 Hovde and representatives of Legacy populated a virtual data room with recent financial information and other relevant information related to Legacy and prepared and updated confidential information memorandum on Legacy. In late February and March 2020, Hovde contacted twenty-five prospects, with eight such parties expressing an interest in obtaining additional information regarding a potential transaction with Legacy. Five prospects, including Seacoast executed nondisclosure agreements and were provided access to the virtual data room. During March of 2020, interested parties conducted due diligence and management meetings were set up with several prospective buyers.

On March 12, 2020, Seacoast entered into an engagement agreement with of Piper Sandler & Co. to serve as its financial advisor in connection with the proposed transaction. Shortly thereafter, the parties paused the conversations relating to a potential transaction due to the onset of the COVID-19 pandemic and the related business and market disruptions. In light of the pandemic, Legacy focused its attention on supporting its communities through the SBA Paycheck Protection Program, cautiously expanding the balance sheet. This allowed Legacy to increase its commercial relationships and manage the risk of its loan portfolio.

In December 2020, management of Legacy instructed Hovde to resume discussions with representatives of Seacoast in an effort to negotiate a transaction. The parties resumed discussions of a potential transaction in early January 2021, with Mr. Shaffer and Mr. Bedley meeting in West Palm Beach. On January 5, 2021, the parties entered into a confidentiality agreement. Legacy then provided updated documents to the data room and Seacoast began conducting due diligence on Legacy.

On February 5, 2021, after discussions between Mr. Shaffer and Mr. Bedley, Seacoast presented a proposed exchange ratio of 0.1703 shares of Seacoast common stock for each share of Legacy common stock, which represented a $5.50 per share price based on Seacoast’s February 4, 2021 closing price. A letter of intent was signed on February 9, 2021, granting Seacoast exclusivity to continue its due diligence review and for the parties to consider, discuss and negotiate any definitive agreement and related agreements until the earlier of March 31, 2021 or the date on which the parties agreed to discontinue discussions. The parties engaged in negotiations over the proposed exchange ratio, finally agreeing to 0.1703 shares of Seacoast common stock for each share of Legacy common stock.

During the remainder of February and March 2021, Seacoast conducted a formal due diligence review of Legacy, which included credit review and management meetings, and the parties began to discuss and negotiate the terms of a definitive agreement.

During February and March 2021, Saltmarsh, Cleaveland & Gund, P.C. conducted a reverse due diligence review of Seacoast on behalf of Legacy.

TABLE OF CONTENTS

In March 2021, additional discussions were held between Seacoast and Legacy representatives concerning the negotiation of definitive transaction agreements, and the parties exchanged and discussed drafts of agreements. During the third week of March 2021, representatives of Legacy and Seacoast continued to negotiate and finalize the definitive transaction agreements, including the merger agreement, voting agreements for directors, noncompetition agreements for directors and officers, claims letters for directors, and agreements with executive officers of Legacy.

On March 18, 2021, Legacy’s board of directors met in special session to review and consider the merger agreement and the transactions and agreements contemplated by it. On March 22, 2021, the board of directors of Legacy held a special meeting with representatives of Hovde and legal counsel to issue final approval of the merger agreement and the merger. The directors reviewed with their advisors the terms of the merger agreement and the merger, and other relevant information. At the meeting, a Hovde representative reviewed with the Legacy board Hovde’s financial analysis summarized below under “— Opinion of Legacy’s Financial Advisor” and delivered to the Legacy board an oral opinion of Hovde, which was later confirmed in writing and is attached to this proxy statement/prospectus as Appendix B, that, based upon and subject to the various considerations set forth in such opinion, the value of the merger consideration to be received by shareholders of Legacy in the merger pursuant to the merger agreement is fair from a financial point of view. In addition, legal counsel reviewed with the directors of Legacy the most recent draft of the proposed merger agreement and related transaction documents, and the legal standards applicable to the Legacy board’s decisions and actions with respect to the proposed transaction. Following a discussion of these matters and other factors listed under “— Recommendation of the Legacy Board of Directors and reasons for the Merger” below, the board of directors of Legacy concluded that the merger of Legacy with and into Seacoast National Bank were fair to and in the best interest of Legacy and its shareholders and unanimously approved and adopted the merger agreement and the transactions contemplated thereby and recommended the Legacy’s shareholders approve the merger agreement.

On March 23, 2021, Seacoast’s board of directors met in special session to review and consider the merger agreement and the transactions and agreements contemplated by it. The management team made a presentation relating to the strategic and financial considerations and rationale of the transaction. Further to this discussion, a representative of Piper Sandler & Co. reviewed the principal terms of the proposed transaction and the financial impacts of the merger on Seacoast and provided comparable transaction analysis for Florida and national bank mergers. Management presented on the loan diligence completed on Legacy’s loan portfolio. At the meeting, Alston & Bird reviewed for the directors the terms and conditions of the merger agreement, the merger and the various agreements to be signed in connection with the merger agreement, and engaged in discussions with the board members on such matters. After additional discussion and deliberation, the Seacoast board of directors adopted and approved the draft merger agreement, including the exchange ratio, and the transactions and agreements contemplated by it (subject to no material terms or conditions being revised) and determined that the merger agreement and the transactions contemplated by it were in the best interests of Seacoast and its shareholders.

On March 23, 2021, the parties signed the merger agreement and the related agreements and a press release announcing the transaction was issued. A conference call to discuss the merger was held the next morning on March 24, 2021.

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

The proximity of SNB and Legacy and the logical geographic scope of the combined bank should position the combined bank for continued organic strategic growth in the combined market area. SNB has an established presence on the Atlantic coast of Southern Florida. This merger creates an excellent opportunity to strengthen SNB’s presence along the Southern Atlantic Coast in Florida and continue expanding in key markets. Joining with SNB will provide Legacy’s customers a broader array of products and services across a larger footprint and create value for Legacy’s employees, customers, and community. SNB operates 48 traditional offices which stretch from Ft. Lauderdale, Boca Raton and West Palm Beach north through the Daytona Beach area, into Orlando and Central Florida and the adjacent Tampa market, and west to Okeechobee and surrounding counties.

Legacy’s board deliberated and unanimously approved the merger agreement at a board meeting held on March 22, 2021. In reaching its determination to approve the merger agreement and the transactions

TABLE OF CONTENTS

contemplated thereby, including the merger, Legacy’s board consulted with Legacy’s management, financial and legal advisors and considered a number of factors, including a fairness opinion presented by Hovde. The following is a discussion of information and factors considered by Legacy’s board in reaching this determination. This discussion is not intended to be exhaustive but includes the material factors considered by Legacy’s board. In the course of its deliberations with respect to the merger, Legacy’s board discussed the anticipated impact of the merger on Legacy, Legacy’s shareholders, and the communities that Legacy serves.

Legacy’s board believes that the merger is in the best interest of Legacy and its shareholders. Accordingly, Legacy’s board has unanimously approved the merger agreement and the transactions contemplated thereby, including the merger, and unanimously recommends that Legacy’s shareholders vote “FOR” approval of the merger agreement and the transactions contemplated thereby.

In approving the merger agreement and the transactions contemplated thereby, including the merger, Legacy’s board consulted with Hovde with respect to the financial aspects of the merger and the fairness of the merger consideration, from a financial point of view, to the holders of shares of Legacy common stock and with its outside legal counsel with respect to its legal duties and the terms of the merger agreement. The Legacy board believes that combining with Seacoast will create a stronger and more diversified organization that will provide significant benefits to Legacy’s shareholders and customers alike.

The terms of the merger agreement, including the consideration to be paid to Legacy’s shareholders, were the result of arm’s-length negotiations between representatives of Legacy and representatives of Seacoast. In arriving at its determination to approve the merger agreement and the transactions contemplated thereby, Legacy’s board considered a number of factors, including the following:

•

the value of the consideration to be received by the shareholders of Legacy relative to the book value and earnings per share of Legacy common stock;

•

the likelihood of success of the combined company in executing on its business strategy;

•

the financial terms of recent business combinations in the financial services industry, particularly in the Southeast, and a comparison of multiples of selected combinations with the terms of the proposed transaction with Seacoast;

•

the historical price performance of Seacoast common stock;

•

the alternatives to the merger, including remaining an independent institution;

•

the competitive and regulatory environment for financial institutions generally;

•

the business prospects for Legacy going forward, as projected by management and viewed in light of the changing economic and competitive landscape;

•

the fact that the merger presents a liquidity opportunity for Legacy’s shareholders;

•

the fact that the merger is structured as a reorganization under Section 368(a) of the Internal Revenue Code;

•

that the exchange ratio is fixed so that if the market price of Seacoast common stock increases, the value of the consideration payable to shareholders of Legacy will be increased proportionately;

•

the opinion of Hovde that the consideration to be received by Legacy’s shareholders as a result of the merger is fair, from a financial point of view, as well as the analysis provided by Hovde;

•

the social, economic, and legal impact of the merger on Legacy’s employees, suppliers, and customers, as well as the communities served by Legacy; and

•

the economy of the State of Florida and the nation.

In addition to the foregoing factors, the board of Legacy also identified and considered a variety of uncertainties and risks concerning the merger, including, but not limited to, the following:

•

the risk that the merger may not be consummated or that the closing may be unduly delayed, including as a result of factors outside either party’s control;

TABLE OF CONTENTS

•

the potential risk of diverting management attention and resources from the operation of Legacy’s business and towards the completion of the merger and the possibility of employee attrition or adverse effects on client and business relationships as a result of the announcement and pendency of the merger;

•

that under the terms of the merger agreement, subject to certain exceptions, Legacy cannot solicit competing acquisition proposals;

•

the potential risks associated with achieving anticipated cost synergies and savings and successfully integrating Legacy’s business, operations and workforce with those of Seacoast and the risk of not realizing all of the anticipated benefits of the merger or not realizing them in the expected timeframe;

•

the possibility that Legacy will have to pay a $4.6 million termination fee to Seacoast if the merger agreement is terminated under certain circumstances; and

•

that the exchange ratio is fixed so that if the market price of Seacoast common stock falls, the value of the consideration payable to shareholders of Legacy will be reduced proportionately.

The foregoing discussion of information and factors considered by Legacy’s board of directors is not intended to be exhaustive but includes the material factors considered by the board of Legacy in approving the merger agreement and the transactions contemplated thereby, including the merger. In reaching its determination, Legacy’s board of directors did not assign any relative or specific weight to different factors and individual directors may have given different weight to different factors. Based on its collective consideration of all of the factors described above, the Legacy’s board of directors concluded that the merger is in the best interest of Legacy and its shareholders and, therefore, the board of Legacy unanimously approved the merger agreement and the transactions contemplated thereby, including the merger. Certain members of the board of directors of Legacy, along with certain officers and 5% shareholders of Legacy have entered into a voting agreement with Seacoast whereby they have agreed to vote their shares of Legacy common stock in favor of the merger. On the record date, these shareholders represented [] shares (or approximately []%) of the Legacy common stock entitled to vote at the Legacy annual meeting.

LEGACY’S BOARD UNANIMOUSLY RECOMMENDS THAT YOU VOTE “FOR” THE MERGER AGREEMENT AND THE TRANSACTIONS CONTEMPLATED THEREBY, INCLUDING THE MERGER.

Seacoast’s Reasons for the Merger

As a part of Seacoast’s growth strategy, Seacoast routinely evaluates opportunities to acquire financial institutions. The acquisition of Legacy is consistent with Seacoast’s expansion strategy. Seacoast’s board of directors and senior management reviewed the business, financial condition, results of operations and prospects for Legacy, the market condition of the market area in which Legacy conducts business, the compatibility of the management and the proposed financial terms of the merger. In addition, management of Seacoast believes that the merger will expand Seacoast’s presence in the attractive Broward and Palm Beach counties, provide opportunities for future growth and provide the potential to realize cost savings. Seacoast’s board of directors also considered the financial condition and valuation for both Legacy and Seacoast as well as the financial and other effects the merger would have on Seacoast’s shareholders. The board considered the fact that the acquisition would increase Seacoast’s existing footprint in Broward and Palm Beach counties, that market overlap would drive cost savings, and that cultural similarities supported the probability of an efficient, low risk integration with minimal customer attrition. In addition, the board of directors also considered the analysis and presentations from its outside financial advisor, Piper Sandler & Co.

While management of Seacoast believes that revenue opportunities will be achieved and costs savings will be obtained following the merger, Seacoast has not quantified the amount of enhancements or projected the areas of operation in which such enhancements will occur.

In view of the variety of factors considered in connection with its evaluation of the merger, the Seacoast board did not find it useful to and did not attempt to quantify, rank or otherwise assign relative weights to factors it considered. Further, individual directors may have given differing weights to different factors. In addition, the Seacoast board did not undertake to make any specific determination as to whether any particular factor, or any aspect of any particular factor, was favorable or unfavorable to its ultimate

TABLE OF CONTENTS

determination. Rather, the board conducted an overall analysis of the factors it considered material, including thorough discussions with, and questioning of, Seacoast’s management.

The fairness opinion and a summary of the underlying financial analyses of Legacy’s financial advisor, Hovde Group, LLC, or Hovde, are described below. The summary and description contains projections, estimates and other forward-looking statements about the future earnings or other measures of the future performance of Legacy. The projections were based on numerous variables and assumptions, which are inherently uncertain, including factors related to general economic and competitive conditions. Accordingly, actual results could vary significantly from those set forth in the projections. You should not rely on any of these statements as having been made or adopted by Legacy, Seacoast, or SNB. You should review the copy of the fairness opinion, which is attached to this proxy statement/prospectus as Appendix B.

Hovde acted as Legacy’s financial advisor in connection with the merger. Hovde is a nationally recognized investment banking firm with substantial experience in transactions similar to the merger and is familiar with Legacy and its operations. As part of its investment banking business, Hovde is continually engaged in the valuation of businesses and their securities in connection with, among other things, mergers and acquisitions. Hovde has experience in, and knowledge of, banks, thrifts and their respective holding companies and is familiar with Legacy. Legacy’s Board of Directors selected Hovde to act as Legacy’s financial advisor in connection with the merger on the basis of the firm’s reputation and expertise in transactions such as the merger.

Hovde reviewed the financial aspects of the proposed merger with Legacy’s Board of Directors, and on March 22, 2021, delivered a written opinion to Legacy’s Board of Directors that, subject to the review, assumptions and limitations set forth in the opinion, the total merger value to be received by the shareholders and option holders of Legacy in the merger pursuant to the merger agreement is fair, from a financial point of view, to the holders of Legacy common stock. In requesting Hovde’s advice and opinion, no limitations were imposed by Legacy upon Hovde with respect to the investigations made or procedures followed by Hovde in rendering its opinion.

The full text of Hovde’s written opinion is included in this this proxy statement/prospectus as Appendix B and is incorporated herein by reference. You are urged to read the opinion in its entirety for a description of the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by Hovde. The summary of Hovde’s opinion included in this proxy statement/prospectus is qualified in its entirety by reference to the full text of such opinion.

Hovde’s opinion was directed to Legacy’s Board of Directors and addresses only the fairness of the total merger value to be received by the shareholders and option holders of Legacy pursuant to the merger agreement in connection with the merger. Hovde did not opine on any individual stock, cash, option, or other components of consideration payable in connection with the merger. Hovde’s opinion did not constitute a recommendation to Legacy as to whether or not Legacy should enter into the merger agreement or to any shareholders of Legacy as to how such shareholders should vote at any meetings of shareholders called to consider and vote upon the merger. Hovde’s opinion does not address the underlying business decision to proceed with the merger or the fairness of the amount or nature of the compensation, if any, to be received by any of the officers, directors or employees of Legacy relative to the amount of consideration to be paid with respect to the merger. Hovde’s opinion should not be construed as implying that the total merger value is necessarily the highest or best price that could be obtained by Legacy in a sale, merger, or combination transaction with a third party. Other than as specifically set forth in the opinion, Hovde is not expressing any opinion with respect to the terms and provisions of the merger agreement or the enforceability of any such terms or provisions. Hovde’s opinion is not a solvency opinion and does not in any way address the solvency or financial condition of Legacy or Seacoast. Hovde’s opinion was approved by Hovde’s fairness opinion committee.

Legacy engaged Hovde on January 30, 2019, to serve as a financial advisor to Legacy in connection with a potential transaction and to issue a fairness opinion to Legacy’s Board of Directors in connection with a potential strategic transaction. Pursuant to Legacy’s engagement agreement with Hovde, Hovde received from Legacy a fairness opinion fee of $100,000 due upon the delivery of the fairness opinion to Legacy and to be

TABLE OF CONTENTS

fully credited one time against any completion fee due Hovde. Upon the consummation of the merger, Hovde will receive a completion fee based on the total merger value, less the fairness opinion fee. Based upon Hovde’s assumption for purposes of its analysis and opinion that the total merger value will be $111,212,341 (as set forth below), the completion fee due Hovde upon the consummation of the merger will be approximately $1,278,942, less the $100,000 credit for the fairness opinion fee, resulting in a net completion fee due Hovde of approximately $1,178,942. In addition to Hovde’s fees, and regardless of whether the merger is consummated, Legacy has agreed to reimburse Hovde for certain of its reasonable out-of-pocket expenses. Legacy has also agreed to indemnify Hovde and its affiliates for certain liabilities that may arise out of Hovde’s engagement. In addition, as the Legacy board was aware, a senior member of the team of investment banking professionals of Hovde advising Legacy in connection with the merger owns 150,000 shares of Legacy common stock. Such member will receive the same consideration for such shares in connection with the merger as other shareholders of Legacy.

Other than in connection with this present engagement, during the two years preceding the date of its opinion, Hovde has not provided investment banking or financial advisory services to Legacy. During the two years preceding the date of its opinion Hovde has not provided any investment banking or financial advisory services to Seacoast for which it received a fee. Hovde or its affiliates may presently or in the future seek or receive compensation from Seacoast in connection with future transactions, or in connection with potential advisory services and corporate transactions, although to Hovde’s knowledge none are expected at this time. In the ordinary course of its business as a broker/dealer, Hovde may from time to time purchase securities from, and sell securities to, Legacy or Seacoast or their affiliates. Except for the foregoing, during the two years preceding the date of this opinion there have not been, and there currently are no mutual understandings contemplating in the future, any material relationships between Hovde and Legacy or Seacoast.

Hovde included in its opinion a summary of selected terms of the merger agreement. This summary is described below and is based on a draft of the merger agreement dated March 18, 2021 provided to Hovde by Legacy. The description below is included for informational purposes only as part of the summary of Hovde’s opinion and has not been updated based on a review of the final merger agreement. Capitalized terms not otherwise defined in the following summary and description have the meanings as set forth in the March 18, 2021 draft merger agreement provided to Hovde by Legacy.

In its opinion, Hovde noted the following: (i) pursuant to the merger agreement, at the Effective Time, Legacy shall be merged with and into SNB in accordance with the provisions of 12 U.S.C. Section 215 and with the effect provided in 12 U.S.C. Section 215; (ii) SNB shall be the surviving bank resulting from the merger and the separate existence of Legacy shall thereupon cease; (iii) SNB shall continue to be governed by the laws of the United States, and the separate existence of SNB with all of its rights, privileges, immunities, powers and franchises shall continue unaffected by the merger; (iv) the surviving bank shall be considered the same business and corporate entity as each constituent bank with all the rights, powers and duties of each constituent bank; (v) it is the intention of the parties to the merger agreement that the merger, for federal income tax purposes, shall qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code and that the merger agreement shall constitute a “plan of reorganization” for purposes of Sections 354 and 361 of the Internal Revenue Code; and (vi) the business purpose of the merger is to combine two financial institutions to create a strong commercial banking franchise.

Hovde also noted the following in its opinion: (i) pursuant to the merger agreement, at the Effective Time, in each case subject to Section 1.4(d) and excluding Excluded Shares and subject to certain adjustments set forth in the merger agreement, by virtue of the merger and without any action on the part of the parties or the holder thereof, each share of Legacy common stock that is issued and outstanding immediately prior to the Effective Time shall be converted into the right to receive, subject to the terms of the merger agreement, the number of shares of Seacoast common stock that is equal to the exchange ratio; provided, however, that in the event the conditions set forth in Section 5.2(j) of the merger agreement are not satisfied, Seacoast shall have the option to adjust the merger consideration downward by an amount that equals the difference between Legacy’s Consolidated Tangible Shareholders’ Equity and the Target Consolidated Tangible Shareholders’ Equity and waive the satisfaction of such condition set forth in Section 5.2(j); and (ii)at least ten (10) days prior to the closing date, Legacy and Seacoast shall agree on a schedule setting forth the expected Legacy Consolidated Tangible Shareholders’ Equity amount as of the closing date. The consideration which all of

TABLE OF CONTENTS

Legacy shareholders are entitled to receive pursuant to the above provisions is collectively referred to as the “aggregate merger consideration” in the sections of this proxy statement/prospectus describing Hovde’s analyses and opinion.

Hovde also noted in its opinion that (i) the obligations of Seacoast to fulfill the terms of the merger agreement and consummate the merger and the other transactions contemplated therein are subject to the satisfaction of the conditions set forth in Section 5.2 of the merger agreement; (ii) Section 5.2(j) of the merger agreement stipulates the requirement that Legacy’s Consolidated Tangible Shareholders’ Equity (as defined in Section 7.1 of the merger agreement) as of the close of business on the fifth business day prior to the closing date shall be an amount not less than the Target Consolidated Tangible Shareholders’ Equity, and Legacy’s general allowance for loan and lease losses shall be an amount not less than 0.75% of total loans and leases outstanding excluding those made pursuant to the Paycheck Protection Program; (iii) the Target Consolidated Shareholders’ Equity is defined as being $58.2 million; and (iv) Seacoast shall have the option to adjust the merger consideration downward by an amount that equals the difference between Legacy’s Consolidated Tangible Shareholders’ Equity and the Target Consolidated Tangible Shareholders’ Equity and waive the satisfaction of such condition set forth in Section 5.2(j) of the merger agreement.

In addition, Hovde noted in its opinion that (i) at the Effective Time, each Legacy Option shall, by virtue of the merger, automatically cease to be outstanding, and, in consideration therefor, Seacoast shall grant to each holder of Legacy Options, as of the Effective Time, an option to purchase shares of Seacoast common stock pursuant to the Seacoast Incentive Plan (each, a “Substitute Seacoast Option”), on the same terms and conditions as applicable to each such Legacy Option as in effect immediately prior to the Effective Time, except that (A) the number of shares of Seacoast common stock subject to such Substitute Seacoast Option shall equal the product of (x) the number of shares of Legacy common stock subject to such Legacy Option immediately prior to the Effective Time, multiplied by (y) the exchange ratio, rounded down to the nearest whole share, and (B) the per share exercise price for the shares of Seacoast common stock issuable upon exercise of such Substitute Seacoast Option shall equal the quotient determined by dividing (x) the exercise price per share of Legacy common stock at which such Legacy Option was exercisable immediately prior to the Effective Time by (y) the Exchange Ratio, rounded up to the nearest whole cent; (ii) no Legacy Equity Award shall be outstanding as of the Effective Time, and no obligations to issue Legacy Equity Awards shall exist following the Effective Time; (iii) prior to the Effective Time, Legacy shall take all actions necessary to effect the treatment of Legacy Options as provided in Section 1.6 of the merger agreement, to terminate Legacy Stock Plans as of the Effective Time, and to cause the provisions in any other Legacy Benefit Plan providing for the issuance, transfer or grant of any capital stock of Legacy or any interest in respect of any capital stock of Legacy to terminate and be of no further force and effect as of the Effective Time.

Additionally, Hovde noted that the merger agreement may be terminated at any time prior to the Effective Time as set forth in Section 6.1 of the merger agreement including among other termination provisions (a) by mutual consent of Seacoast and Legacy; (b) by either party in the event that (i) any Regulatory Consent required to be obtained from any governmental authority has been denied or (ii) Legacy Shareholder Approval has not been obtained by reason of the failure to obtain the required vote at the Legacy shareholders’ meeting where the merger agreement was presented to such shareholders for approval and voted upon; (c) by either party in the event that the merger has not been consummated by October 31, 2021; (d) by Seacoast in the event that (i) Legacy has withdrawn, qualified or modified the Legacy directors’ recommendation in a manner adverse to Seacoast or shall have resolved to do any of the foregoing, (ii) Legacy has failed to substantially comply with its obligations under Sections 4.5 or 4.12, or (iii) the Board of Directors of Legacy has recommended, endorsed, accepted or agreed to an Acquisition Proposal; (e) by Legacy in the event that (i) the Board of Directors of Legacy has determined in accordance with Section 4.12 that a Superior Proposal has been made with respect to it and has not been withdrawn, and (ii) neither Legacy nor any of its Representatives has failed to comply in all material respects with Section 4.12; and (f) by Seacoast if holders of more than five percent (5.0%) in the aggregate of the outstanding shares of Legacy common stock shall have voted such shares against the merger agreement or the merger at any meeting called for the purpose of voting thereon. Hovde further noted that in the event that the merger agreement is terminated pursuant to certain conditions of Section 6.1, including termination if Legacy shall have received or there shall have been publicly announced an Acquisition Proposal that has not been formally withdrawn or abandoned prior to such termination, and within twelve (12) months following such termination an Acquisition Proposal is consummated or a definitive

TABLE OF CONTENTS

agreement or letter of intent is entered into by Legacy with respect to an Acquisition Proposal, Legacy shall pay Seacoast a termination fee of $4,600,000.

With Legacy’s knowledge and consent and for purposes of its analysis and opinion, Hovde assumed that (i) the closing price of Seacoast common stock on March 19, 2021 is $38.24 per share; (ii) the exchange ratio is 0.1703 and has not been adjusted as provided in the merger agreement; (iii) there has been no downward adjustment of the merger consideration due to Legacy’s Consolidated Tangible Shareholders’ Equity being less than the Target Consolidated Tangible Shareholders’ Equity; and (iv) there are 15,772,897 shares of Legacy common stock outstanding as of March 19, 2021, and thereby, the value of the aggregate merger consideration is $103,335,204. Additionally, Hovde assumed that (i) there are Legacy Options outstanding as of March 19, 2021 to purchase 2,128,754 shares of Legacy common stock; (ii) the weighted average exercise price per share of Legacy’s options as of March 19, 2021 is $2.85 per share of Legacy common stock; and (iii) there would be issued 362,527 Substitute Seacoast Options to purchase Seacoast common stock at $16.74 per Seacoast share, and thereby, the total Legacy Option Value is $7,877,136. The total merger value is equal to the sum of the value of the aggregate merger consideration of $103,335,204 plus the value of the total Legacy option value of $7,877,136, and therefore for purposes of its analysis and opinion, Hovde assumed that the total merger value is $111,212,341.

The following is a summary of the analyses performed and matters considered by Hovde in connection with its fairness opinion. The summary set forth below does not purport to be a complete description of all of the analyses performed by Hovde in rendering its opinion, but it does summarize all of the material analyses performed by Hovde. During the course of its engagement and for the purposes of its fairness opinion, Hovde:

(i)

reviewed a draft of the merger agreement dated March 18, 2021 as provided to Hovde by Legacy;

(ii)

reviewed unaudited financial statements for Legacy for the twelve month period ended December 31, 2020;

(iii)

reviewed certain historical annual reports of Legacy, including Legacy’s audited annual report for the years ended December 31, 2019 and 2018;

(iv)

reviewed certain historical publicly available business and financial information concerning Legacy;

(v)

reviewed certain internal financial statements and other financial and operating data concerning Legacy;

(vi)

reviewed financial projections prepared by certain members of senior management of Legacy;

(vii)

discussed with certain members of senior management of Legacy the business, financial condition, results of operations and future prospects of Legacy; the history and past and current operations of Legacy; and Legacy’s and Seacoast’s assessment of the rationale for the merger;

(viii)

reviewed and analyzed materials detailing the merger prepared by Seacoast and Legacy;

(ix)

assessed current general economic, market and financial conditions;

(x)

reviewed the terms of recent merger, acquisition and control investment transactions, to the extent publicly available, involving financial institutions and financial institution holding companies that Hovde considered relevant;

(xi)

took into consideration Hovde’s experience in other similar transactions and securities valuations as well as Hovde’s knowledge of the banking and financial services industry;

(xii)

reviewed certain publicly available financial and stock market data relating to selected public companies that Hovde deemed relevant to its analysis; and

(xiii)

performed such other analyses and considered such other factors as Hovde deemed appropriate.

Hovde assumed, without investigation, that there have been, and from the date of its opinion through the Effective Time will be, no material changes in the financial condition and results of operations of Legacy or Seacoast since the date of the latest financial information described above. Hovde further assumed, without

TABLE OF CONTENTS

independent verification, that the representations and financial and other information included in the merger agreement and all other related documents and instruments that are referred to therein or were otherwise provided to Hovde by Legacy and Seacoast are true and complete. Hovde relied upon the management of Legacy as to the reasonableness and achievability of the financial forecasts, projections and other forward-looking information provided to Hovde by Legacy and Seacoast and Legacy’s professionals, and Hovde assumed such forecasts, projections and other forward-looking information were reasonably prepared by Legacy, Seacoast and Legacy’s professionals on a basis reflecting the best currently available information and Legacy’s, Seacoast’s and Legacy’s professionals judgments and estimates. Hovde assumed that such forecasts, projections and other forward-looking information would be realized in the amounts and at the times contemplated thereby, and Hovde does not assume any responsibility for the accuracy or reasonableness thereof. Hovde was authorized by Legacy to rely upon such forecasts, projections and other information and data, and Hovde expresses no view as to any such forecasts, projections or other forward-looking information or data, or the bases or assumptions on which they were prepared.

In performing its review, Hovde assumed and relied upon the accuracy and completeness of all of the financial and other information that was available to Hovde from public sources, that was provided to Hovde by Legacy or Seacoast or their respective representatives or that was otherwise reviewed by Hovde for purposes of rendering its opinion. Hovde further relied on the assurances of the respective managements of Legacy and Seacoast that they were not aware of any facts or circumstances that would make any of such information inaccurate or misleading. Hovde was not asked to undertake, and did not undertake, an independent verification of any of such information, and Hovde does not assume any responsibility or liability for the accuracy or completeness thereof. Hovde assumed that each party to the merger agreement would advise Hovde promptly if any information previously provided to Hovde became inaccurate or was required to be updated during the period of its review.

Hovde is not expert in the evaluation of loan and lease portfolios for purposes of assessing the adequacy of the allowances for losses with respect thereto. Hovde assumed that such allowances for Legacy and Seacoast are, in the aggregate, adequate to cover such losses and will be adequate on a pro forma basis for the combined entity. Hovde was not requested to make, and did not make, an independent evaluation, physical inspection or appraisal of the assets, properties, facilities, or liabilities (contingent or otherwise) of Legacy or Seacoast, the collateral securing any such assets or liabilities, or the collectability of any such assets, and Hovde was not furnished with any such evaluations or appraisals; nor did Hovde review any loan or credit files of Legacy or Seacoast.

Hovde undertook no independent analysis of any pending or threatened litigation, regulatory action, possible unasserted claims or other contingent liabilities to which Legacy or Seacoast was or is a party or may be subject, and Hovde’s opinion made no assumption concerning, and therefore does not consider, the possible assertion of claims, outcomes or damages arising out of any such matters. Hovde also assumed, with Legacy’s consent, that Legacy and Seacoast were not parties to any material pending transaction, including without limitation any financing, recapitalization, acquisition or merger, divestiture or spin-off, other than the merger contemplated by the merger agreement.

Hovde relied upon and assumed, with Legacy’s consent and without independent verification, that the merger will be consummated substantially in accordance with the terms set forth in the merger agreement, without any waiver of material terms or conditions by Legacy, Seacoast or any other party to the merger agreement and that the final merger agreement will not differ materially from the draft Hovde reviewed. Hovde assumed that the merger will be consummated in compliance with all applicable laws and regulations. Legacy advised Hovde that they were not aware of any factors that would impede any necessary regulatory or governmental approval of the merger. Hovde assumed that the necessary regulatory and governmental approvals as granted would not be subject to any conditions that would be unduly burdensome on Legacy or Seacoast or would have a material adverse effect on the contemplated benefits of the merger.

Hovde’s opinion does not consider, include or address: (i) any legal, tax, accounting, or regulatory consequences of the merger on Legacy or its shareholders; (ii) any advice or opinions provided by any other advisor to the Board of Directors of Legacy or Legacy; (iii) any other strategic alternatives that might be available to Legacy; or (iv) whether Seacoast has sufficient cash or other sources of funds to enable it to pay the consideration contemplated by the merger.

TABLE OF CONTENTS

Hovde’s opinion was based solely upon the information available to Hovde and described above, and the economic, market and other circumstances as they existed as of the date thereof. Events occurring and information that becomes available after the date thereof could materially affect the assumptions and analyses used in preparing its opinion. Hovde has not undertaken to update, revise, reaffirm or withdraw its opinion or to otherwise comment upon events occurring or information that becomes available after the date thereof.

The following is a summary of the material analyses prepared by Hovde and delivered to Legacy’s Board of Directors on March 22, 2021 in connection with the delivery of its fairness opinion. This summary is not a complete description of all the analyses underlying the fairness opinion or the presentation prepared by Hovde, but it summarizes the material analyses performed and presented in connection with such opinion. The preparation of a fairness opinion is a complex analytical process involving various determinations as to the most appropriate and relevant methods of financial analysis, and the application of those methods to the particular circumstances of the contemplated Merger. Therefore, a fairness opinion is not readily susceptible to partial analysis or summary description. In arriving at its opinion, Hovde did not attribute any particular weight to any analysis or factor that it considered, but rather made qualitative judgments as to the significance and relevance of each analysis and factor. The financial analyses summarized below include information presented in tabular format. The analyses and the summary of the analyses must be considered as a whole, and selecting portions of the analyses and factors or focusing on the information presented below in tabular format, without considering all analyses and factors or the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of the process underlying the analyses and opinion of Hovde. The tables alone are not a complete description of the financial analyses.

Market Approach — Comparable Merger and Acquisition Transactions. As part of its analysis, Hovde reviewed publicly available information related to two comparable groups (a “Regional Group” and a “Nationwide Group”) of select acquisition transactions of banks. The Regional Group consisted of acquisition transactions where targets were headquartered in Alabama, Arkansas, Florida, Georgia, Mississippi, North Carolina, South Carolina, Tennessee, Virginia and West Virginia announced since January 1, 2018, in which the targets’ total assets were between $300 million and $1.0 billion, last-twelve-months return on average assets was greater than 0.75% and nonperforming assets to total assets was less than 1.50%. The Nationwide Group consisted of acquisition transactions of banks in the United States announced since January 1, 2018, in which the targets’ total assets were between $400 million and $750 million, last-twelve-months return on average assets was between 0.90% and 1.50%, nonperforming assets to total assets was less than 1.50%, and tangible equity to tangible assets was greater than 9.00%. In each case, for which financial information was available, no transaction that fit the above selection criteria was excluded. Information for the target institutions was based on balance sheet data as of, and income statement data for, the twelve months preceding the most recent quarter prior to announcement of the transactions. The resulting two groups consisted of the following precedent transactions (14 transactions for the Regional Group and 16 transactions for the Nationwide Group):

For each precedent transaction, Hovde compared the implied ratio of the total merger value to certain financial characteristics of Legacy as follows:

•

the multiple of the total merger value to the acquired company’s last twelve months, or “LTM,” net earnings per share (the “Price-to-LTM Earnings Multiple”);

•

the multiple of the total merger value to the acquired company’s common tangible book value (the “Price-to-Common Tangible Book Value Multiple”);

•

the multiple of the value of the total merger value to the acquired company’s adjusted common tangible book value (the “Price-to-Adjusted Common Tangible Book Value Multiple”); and

•

the multiple of the difference between the total merger value and the acquired company’s common tangible book value to the acquired company’s core deposits (the “Premium-to-Core Deposits Multiple”).

The results of the analysis are set forth in the table below. Transaction multiples for the merger were based upon the total merger value assumed by Hovde of $111,212,341 and were based on December 31, 2020 financial results for Legacy.

	Price-to-LTM Earnings Multiple		Price-to-Common Tangible Book Value Multiple		Price-to-Adjusted Common Tangible Book Value Multiple(1)		Premium-to-Core Deposits Multiple(1)(2)

TABLE OF CONTENTS

(1)

Price-to-Adjusted Common Tangible Book Value equals the adjusted purchase price divided by core capital where: (a) core capital equals total tangible assets multiplied by 8%; (b) excess capital equals total common tangible book value less core capital; and (c) adjusted purchase price equals the total merger value less excess capital (assumes dollar-for-dollar payment on excess capital).

(2)

Represents the premium of the total merger value over Common Tangible Book Value, expressed as a percentage of Core Deposits. Core deposits are defined as total deposits less foreign deposits and time deposit accounts greater than $100,000.

Using publicly available information, Hovde compared the financial performance of Legacy with that of the median of the precedent merger and acquisition transactions from both the Regional and Nationwide Groups. The performance highlights are based on December 31, 2020 financial results of Legacy.

Core deposits exclude foreign deposits and time deposit accounts greater than $100,000.

(2)

LTM ROAA and LTM ROAE are shown tax-affected for S Corporations.

(3)

Nonperforming assets as a percentage of total assets (includes restructured loans and leases).

(4)

Loan Loss Reserve (“LLR”) as a percentage of nonperforming loans (“NPLs”).

No company or transaction used as a comparison in the above transaction analyses is identical to Legacy, and no transaction was consummated on terms identical to the terms of the merger agreement. Accordingly, an analysis of these results is not strictly mathematical. Rather, it involves complex considerations and judgments concerning differences in financial and operating characteristics of the companies. The resulting values of the Precedent Transactions Regional Group using the median values for the four valuation metrics set forth above indicated an implied total valuation ranging between $88.9 million and $98.8 million with a four factor implied total valuation average of $93.4 million compared to the total merger value assumed by Hovde of $111.2 million. The resulting values of the Precedent Transactions Nationwide Group using the median values for the four valuation metrics set forth above indicated an implied total valuation ranging between $89.4 million and $95.7 million with a four factor implied total valuation average of $92.4 million compared to the total merger value assumed by Hovde of $111.2 million.

Income Approach — Discounted Cash Flow Analysis. Taking into account various factors including, but not limited to, Legacy’s recent performance, the current banking environment and the local economy in which Legacy operates, Hovde determined, in consultation with and based on information provided by management of Legacy, net income estimates for Legacy over a forward looking five year period, and in consultation with Legacy management, developed the forward-looking projections and key assumptions which formed the basis for the discounted cash flow analyses. The resulting projected Legacy net income numbers used for the analysis were $8.5 million for 2021, $9.6 million for 2022, $10.0 million for 2023, $11.0 million for 2024 and $12.1 million for 2025. No dividends were assumed to be paid by Legacy over the projection period.

To determine present values of Legacy based on these projections, Hovde utilized two discounted cash flow models, each of which capitalized terminal values using different multiples: (1) Terminal Price/Earnings Multiple (“DCF Terminal P/E Multiple”); and, (2) Terminal Price/Adjusted Common Tangible Book Value Multiple (“DCF Terminal P/Adj. TBV Multiple”).

In the DCF Terminal P/E Multiple analysis, an estimated value of Legacy common stock was calculated based on the present value of Legacy’s net income based on Legacy management’s forward-looking projections

TABLE OF CONTENTS

over the five year projection period. The projected 2025 net income amount was $12.1 million and served as the basis of the terminal earnings value in the DCF. Hovde utilized a terminal value at the end of 2025 by applying a five point range of price-to-earnings multiples of 13.3x to 17.3x, which is based around the median price-to-earnings multiple derived from transactions in the Regional Group of 15.3x. The present value of Legacy’s projected terminal value was then calculated assuming a range of discount rates between 14.60% and 16.60%, with a midpoint of 15.60% discounted over a period of 4.79 years. This range of discount rates was chosen to reflect different assumptions regarding the required rates of return of holders or prospective holders of Legacy common stock. The range of discount rates utilized the buildup method to determine such required rates of return and was based upon the risk-free interest rate, an equity risk premium, an industry risk premium and a size premium which resulted in a discount rate of 15.60% used as the midpoint of the five point range of discount rates of 14.60% to 16.60%. The resulting total values of Legacy common stock based on the DCF Terminal P/E Multiple applied to the 2025 projected earnings of $12.1 million and then discounted over a 4.79 year period utilizing the five point range of discount rates set forth above resulted in implied total values between $77.0 million and $108.9 million with a midpoint of $92.3 million compared to the total merger value assumed by Hovde of $111.2 million.

In the DCF Terminal P/Adj. TBV Multiple model, the same earnings estimates and projected net income were used as in the preceding DCF Terminal P/E Multiple analysis to determine the projected adjusted common tangible book value for Legacy as of December 31, 2025 of $70.8 million with excess tangible book value of $37.4 million. For purposes of the analysis, projected adjusted tangible book value was assumed to be equal to total tangible assets multiplied by 8.0%. In arriving at the terminal value at the end of 2025, Hovde applied a five point range of price-to-adjusted common tangible book value multiples of 1.80x to 2.00x utilizing as a midpoint of the range the median price-to-adjusted common tangible book value multiple derived from precedent transactions in the Regional Group of 1.90x and assumed dollar-for-dollar payment on excess tangible book value. The present value of the projected terminal value was then calculated assuming the range of discount rates between 14.60% and 16.60%, with a midpoint of 15.60% discounted over a period of 4.79 years as was applied in the DCF Terminal P/E Multiple analysis set forth above. The resulting implied total values of Legacy common stock based on the DCF Terminal P/Adj. TBV Multiple analysis ranged between $79.2 million and $93.4 million with a midpoint of $86.0 million compared to the total merger value assumed by Hovde of $111.2 million.

These analyses and their underlying assumptions yielded a range of implied multiple values for Legacy common stock which are outlined in the table below:

Hovde noted that while the discounted cash flow present value analysis is a widely used valuation methodology, it relies on numerous assumptions, including asset and earnings growth rates, projected dividend payouts, terminal values and discount rates. Hovde’s analysis does not purport to be indicative of the actual values or expected total values of Legacy common stock.

The table below summarizes the analyses performed under the Market Approach and the Income Approach described above.

Seacoast Comparable Companies Analysis: Hovde used publicly available information to compare selected financial and trading information for Seacoast and a group of 8 publicly-traded financial institutions selected by Hovde which was based on publicly-traded banks headquartered in Alabama, Arkansas, Florida, Georgia, Mississippi, North Carolina, South Carolina, Tennessee, Virginia and West Virginia with total assets between $5.0 billion and $15.0 billion. The following publicly-traded financial institutions comprised the comparable peer group:

Renasant Corporation
Towne Bank
ServisFirst Bancshares, Inc.
FB Financial Corporation

Amerant Bancorp, Inc.
First Bancorp
City Holding Company
First Bancshares, Inc.

The analysis compared publicly available financial and market trading information for Seacoast and the data for the 8 financial institutions identified above as of and for the most recent twelve-month period which was publicly available. The table below compares the data for Seacoast and the median data for the 8 financial institutions identified above, with pricing data as of March 19, 2021.

	Market Cap ($M)			Price/ Tangible Book Value		Price/ 2020A EPS		Price/ 2021E EPS		Dividend Yield		YTD Price Change		Two Year Total Return
Seacoast		$	2,109.1		237.6%		26.7x		20.7x		0.00%		30.6%		34.5%
Comparable Companies:
Median		$	1,781.5		211.5%		16.5x		16.7x		1.55%		34.3%		31.3%

TABLE OF CONTENTS

Seacoast fell within the range of pricing metrics of comparable companies. No company used as a comparison in the above analyses is identical to Seacoast. Accordingly, an analysis of these results is not strictly mathematical. Rather, it involves complex considerations and judgments concerning differences in financial and operating characteristics of the companies.

Other Factors and Analyses. Hovde took into consideration various other factors and analyses, including but not limited to: current market environment; merger and acquisition environment; movements in the common stock valuations of selected publicly-traded banking companies; and movements in the Russell 3000 Index.

Conclusion. Based upon the foregoing analyses and other investigations and assumptions as set forth in its opinion, without giving specific weightings to any one factor, analysis or comparison, Hovde determined that, as of the date of its opinion, subject to the review, assumptions and limitations set forth in the opinion, the total merger value to be received by the shareholders and option holders of Legacy in the merger pursuant to the merger agreement is fair, from a financial point of view, to the holders of Legacy common stock.

Each Legacy shareholder is encouraged to read Hovde’s fairness opinion in its entirety. The full text of this fairness opinion is included in this proxy statement/prospectus as Appendix B.

Material U.S. Federal Income Tax Consequences of the Merger

The following discussion describes the anticipated material U.S. federal income tax consequences of the merger to U.S. holders (as defined below) of Legacy common stock that exchange their shares of Legacy common stock for shares of Seacoast common stock in the merger. This summary is based upon the Code, Treasury regulations promulgated thereunder, judicial authorities, published positions of the Internal Revenue Service and other applicable authorities, all as currently in effect as of the date hereof, and all of which are subject to change, possibly with retroactive effect. Any such change could affect the accuracy of the statements and conclusions set forth in this discussion.

For purposes of this discussion, a “U.S. holder” means a beneficial owner of Legacy common stock that is for U.S. federal income tax purposes (i) an individual citizen or resident of the U.S., (ii) a corporation, or entity treated as a corporation, organized in or under the laws of the U.S. or any state or political subdivision thereof or the District of Columbia, (iii) a trust if (a) a court within the U.S. is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have the authority to control all substantial decisions of the trust or (b) such trust has made a valid election to be treated as a U.S. person for U.S. federal income tax purposes, or (iv) an estate, the income of which is includible in gross income for U.S. federal income tax purposes regardless of its source. This discussion addresses only U.S. holders of Legacy common stock.

This discussion addresses only those Legacy common shareholders that hold their shares of Legacy common stock as a capital asset within the meaning of Section 1221 of the Code (generally, stock held for investment). Further, this discussion does not address all aspects of U.S. federal income taxation that may be relevant to you in light of your particular circumstances or if you are subject to special treatment under the U.S. federal income tax laws, including if you are

•

a financial institution;

•

a tax-exempt organization;

•

an S corporation or other pass-through entity (or an investor in an S corporation or other pass-through entity);

•

retirement plans, individual retirement accounts or other tax-deferred accounts;

•

an insurance company;

•

a regulated investment company;

•

a real estate investment trust;

•

a dealer or broker in stocks and securities, commodities or currencies;

•

a trader in securities that elects the mark-to-market method of accounting;

TABLE OF CONTENTS

•

a holder of Legacy stock that received such stock through the exercise of an employee stock option, through a tax qualified retirement plan or otherwise as compensation;

•

a person that is not a U.S. holder (as defined above);

•

a person that has a functional currency other than the U.S. dollar;

•

a holder of Legacy stock that holds such stock as part of a hedge, straddle, constructive sale, conversion or other integrated transaction; or

•

a U.S. expatriate.

In addition, the discussion does not address any alternative minimum tax or any state, local or foreign tax consequences of the merger, and it does not address any other U.S. federal tax consequences (such as gift or estate taxes or the unearned income Medicare contribution tax). The actual tax consequences of the merger to you may be complex. These consequences will depend on your individual situation. Holders of Legacy common stock are urged to consult with their own tax advisors as to the tax consequences of the merger in their particular circumstances, including the applicability and effect of the alternative minimum tax and any state, local or foreign and other tax laws and of any changes in those laws.

If a partnership (including for this purpose any entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds Legacy common stock, the tax treatment of a partner generally will depend on the status of the partner and the activities of the partnership. Partners in a partnership holding Legacy common stock should consult their own tax advisors.

Tax Consequences of the Merger Generally

The parties intend for the merger to qualify as a reorganization within the meaning of Section 368(a) of the Code. It is a condition to Seacoast’s obligation to complete the merger that it receive an opinion from Alston & Bird LLP, dated the closing date of the merger, to the effect that the merger will qualify as a reorganization within the meaning of Section 368(a) of the Code, and it is a condition to Legacy’s obligation to complete the merger that it receive an opinion from Fenimore, Kay, Harrison & Ford, LLP, dated as of the closing date of the merger, to the effect that the merger will qualify as a reorganization within the meaning of Section 368(a) of the Code. The opinion of Alston & Bird LLP provided on behalf of Seacoast and the opinion of Fenimore, Kay, Harrison & Ford, LLP provided on behalf of Legacy will each be based on representation letters provided by Seacoast and Legacy and on customary factual assumptions. The opinions described above will not be binding on the Internal Revenue Service or any court. Legacy and Seacoast have not sought and will not seek any ruling from the Internal Revenue Service regarding any matters relating to the merger. There can be no assurance that the Internal Revenue Service will not assert, or that a court would not sustain, a position contrary to any of the conclusions set forth in this discussion. In addition, if any of the representations or assumptions upon which these opinions are based are inconsistent with the actual facts, the U.S. federal income tax consequences of the merger could be adversely affected.

Provided the merger qualifies as a “reorganization” within the meaning of Section 368(a) of the Code, each of Seacoast and Legacy will be a party to such reorganization within the meaning of Section 368(b) of the Code, and neither Seacoast nor Legacy will recognize any gain or loss as a result of the merger.

Provided the merger qualifies as a “reorganization” within the meaning of Section 368(a) of the Code, as a U.S. holder of Legacy common stock that exchanges all of your Legacy common stock for Seacoast common stock, you will not recognize income, gain or loss for U.S. federal income tax purposes, except, as discussed below, with respect to cash received in lieu of fractional shares of Seacoast common stock or upon the exercise of dissenters’ rights.

The aggregate tax basis of the Seacoast common stock you receive in the merger (including any fractional shares deemed received and redeemed for cash as described below) will be the same as the aggregate tax basis of the Legacy common stock surrendered in exchange therefor, reduced by any basis allocable to a fractional share of Seacoast common stock for which cash is received. The holding period of the Seacoast common stock received (including any fractional shares deemed received and sold for cash as described below) will include the holding period of the Legacy shares surrendered.

TABLE OF CONTENTS

If a U.S. holder acquired different blocks of Legacy common stock at different times or at different prices, the Seacoast common stock such holder receives will be allocated pro rata to each block of Legacy common stock, and the basis and holding period of each block of Seacoast common stock such holder receives will be determined on a block-for-block basis depending on the basis and holding period of the blocks of Legacy common stock exchanged for such block of Seacoast common stock.

Cash In Lieu of Fractional Shares

If you receive cash in lieu of a fractional share of Seacoast common stock, you will be treated as having received the fractional share of Seacoast common stock pursuant to the merger and then as having sold that fractional share of Seacoast common stock for cash in a redemption by Seacoast. As a result, assuming that the cash received is not treated as a dividend (as described below), you generally will recognize gain or loss equal to the difference between the amount of cash received and the tax basis allocated to such fractional share. This gain or loss generally will be capital gain or loss and generally will be long-term capital gain or loss if, as of the effective date of the merger, your holding period for the shares (including the holding period of the Legacy common stock deemed surrendered in exchange for a fractional share of Seacoast common stock) is greater than one year. The deductibility of capital losses is subject to limitations.

Potential Dividend Treatment

In some cases, if a holder of Legacy common stock actually or constructively owns shares of Seacoast common stock (other than the shares of Seacoast common stock received as consideration in connection with the merger), the holder’s recognized gain could be treated as having the effect of the distribution of a dividend under the tests set forth in Section 302 of the Code, in which case such gain would be treated as dividend income to the extent of the holder’s ratable share of Seacoast’s accumulated earnings and profits (as calculated for U.S. federal income tax purposes). The determination of whether a U.S. holder will recognize a capital gain or dividend income as a result of its exchange of Legacy common stock in the merger is complex and must be determined on a stockholder-by-stockholder basis. Accordingly, each holder should consult his, her or its own independent tax advisor as to the tax consequences of the merger, including such determination, in its particular circumstances.

Information Reporting and Backup Withholding

In certain instances, you may be subject to information reporting and backup withholding (currently at a rate of 24%) on any cash payments you receive. You generally will not be subject to backup withholding, however, if you:

•

furnish a correct taxpayer identification number, certify that you are not subject to backup withholding on the substitute Form W-9 or successor form included in the letter of transmittal you will receive and otherwise comply with all the applicable requirements of the backup withholding rules; or

•

provide proof that you are otherwise exempt from backup withholding.

Any amounts withheld under the backup withholding rules are not additional tax and will generally be allowed as a refund or credit against your U.S. federal income tax liability, provided you timely furnish the required information to the Internal Revenue Service.

A Legacy shareholder who receives Seacoast common stock as a result of the merger will be required to retain records pertaining to the merger. Each Legacy shareholder who is required to file a U.S. federal income tax return and who is a “significant holder” that receives Seacoast common stock in the merger will be required to file a statement with such U.S. federal income tax return in accordance with Treasury regulations Section 1.368-3 setting forth information regarding the parties to the merger, the date of the merger, such Legacy shareholder’s basis in the Legacy common stock surrendered and the fair market value of the Seacoast common stock received in the merger. A “significant holder” is a holder of Legacy common stock who, immediately before the merger, owned at least 1% (by vote or value) of the outstanding stock of Legacy or securities of Legacy with a basis for U.S. federal income tax purposes of at least $1 million.

TABLE OF CONTENTS

Exercise of Dissenters’ Rights

As part of the exercise of dissenters’ rights, a Legacy shareholder will exchange all of its Legacy common stock for cash. A U.S. holder that receives only cash in exchange for its Legacy common stock will generally recognize gain or loss equal to the difference between the amount of cash received and such U.S. holder’s adjusted tax basis in its Legacy common stock. This gain or loss generally will be capital gain or loss and will be long-term capital gain or loss if the U.S. holder’s holding period for its shares of Legacy common stock exceeds one year. Long-term capital gain of non-corporate taxpayers, including individuals, is generally taxed at preferential rates. The deductibility of capital losses may be subject to limitations.

This discussion of certain material U.S. federal income tax consequences is for general information purposes only and is not tax advice. Holders of Legacy common stock are urged to consult their tax advisors with respect to the application of U.S. federal income tax laws to their particular situations as well as any tax consequences arising under the U.S. federal estate or gift tax rules, or under the laws of any state, local, foreign or other taxing jurisdiction or under any applicable tax treaty. Holders of Legacy common stock are also urged to consult their tax advisors with respect to the effect of possible changes in any of those laws after the date of this proxy statement/prospectus.

Accounting Treatment

The merger will be accounted for using the acquisition method of accounting with Seacoast treated as the acquiror. Under this method of accounting, Legacy’s assets and liabilities will be recorded by Seacoast at their respective fair values as of the date of completion of the merger. Financial statements of Seacoast issued after the merger will reflect these values and will not be restated retroactively to reflect the historical financial position or results of operations of Seacoast.

Regulatory Approvals

Under federal law, the merger must be approved by the OCC. After receipt of approval of the merger from the OCC, the parties must wait for up to 30 days before completing the merger. If, however, there are no adverse comments from the U.S. Department of Justice and Seacoast receives permission from the OCC to do so, the merger may be completed on or after the fifteenth (15th) day after approval from the OCC.

As of the date of this proxy statement/prospectus, all of the required regulatory applications have been filed. There is no assurance as to whether the regulatory approvals will be obtained or as to the date of such approval. There also can be no assurance that the regulatory approvals received will not contain a condition that would increase any of the minimum regulatory capital requirements of Seacoast following the merger or have a material adverse effect. See “The Merger Agreement — Conditions to Completion of the Merger.”

Dissenters’ Rights for Legacy Shareholders

Notwithstanding any other provisions of this proxy statement/prospectus, shares of Legacy common stock issued and outstanding at the effective time of the merger which are held by a Legacy shareholder who perfects his or her dissenters’ rights in accordance with Section 658.44 of the FFIC and Sections 607.1301 through 607.1340 of the FBCA (which we refer to as “dissenting shares”) will not be converted into or represent the right to receive the merger consideration, and any such holder will be entitled only to such rights of appraisal as are granted by Section 658.44 of the FFIC, unless and until such holder fails to perfect or effectively withdraws or otherwise loses his or her right to appraisal; provided, however, that no payment in connection with dissenting shares will be made to any dissenting shareholder unless and until such dissenting shareholder has complied with the applicable provisions of the FFIC and surrendered to Seacoast the certificate or certificates representing the dissenting shares for which payment is being made. If after the effective time of the merger any such dissenting shareholder fails to perfect or effectively withdraws or loses his or her right to appraisal, such shares of common stock shall be treated as if they had been converted at the effective time of the merger into the right to receive the merger consideration. Legacy must give Seacoast prompt notice of any written demands for appraisal, attempted withdrawals of such demands and any other instruments served pursuant to applicable law received by Legacy relating to shareholders’ rights of appraisal (any shareholder making such demand is referred to as a “dissenting shareholder”). Each dissenting shareholder that becomes entitled to payment for any shares of common stock held by such dissenting

TABLE OF CONTENTS

shareholder will receive payment from Seacoast pursuant to the FFIC and FBCA. The value of the dissenting shares, as determined in accordance with the FFIC, may be less than the value of the shares of Legacy common stock such shareholder would otherwise receive pursuant to the merger agreement.

TO THE SHAREHOLDERS OF LEGACY:

YOU ARE HEREBY NOTIFIED THAT YOU MAY BE ENTITLED TO ASSERT DISSENTERS’ RIGHTS PURSUANT TO FLORIDA STATUTES SECTION 658.44 AND SECTIONS 607.1301 THROUGH 607.1340, A COPY OF WHICH IS ATTACHED IN ITS ENTIRETY AS APPENDIX C TO THIS PROXY STATEMENT/PROSPECTUS.

Any Legacy shareholder desiring to assert dissenters’ rights (1) must vote “AGAINST” the merger proposal at the Legacy annual meeting or (2) must deliver to Legacy at or prior to the Legacy annual meeting written notice of the shareholder’s intent to demand payment for the shares of Legacy common stock if the merger proposal is approved, and must not vote “FOR” the merger proposal. On or promptly after the effective time of the merger, Seacoast may fix an amount which it considers to be not more than the fair market value of the shares of Legacy common stock and which it will pay to the dissenting shareholders and, if it fixes such amount, will offer to pay such amount to the holders of all dissenting shares of Legacy. The owners of dissenting shares who have accepted such offer will be entitled to receive the amount so offered for such shares in cash upon surrendering the stock certificates representing such shares at any time within 30 days after the effective date of the merger.

This is not a complete statement of all applicable requirements and is qualified in its entirety by reference to Section 658.44 of the FFIC and Sections 607.1301 through 607.1340 of the FBCA, which is reproduced in its entirety as Appendix C to this proxy statement/prospectus.

For a discussion of tax consequences with respect to dissenting shares, see “The Merger — Material U.S. Federal Income Tax Consequences of the Merger — Exercise of Dissenters’ Rights.”

BECAUSE OF THE COMPLEXITY OF THE PROVISIONS OF FLORIDA LAW RELATING TO DISSENTERS’ RIGHTS, SHAREHOLDERS WHO ARE CONSIDERING DISSENTING FROM THE MERGER ARE URGED TO CONSULT THEIR OWN LEGAL ADVISORS.

Board of Directors and Management of Seacoast and SNB Following the Merger

The members of the board of directors and officers of Seacoast and SNB immediately prior to the effective time of the merger will be the directors and officers of the surviving bank and will hold office until their respective successors are duly elected and qualified, or their earlier death, resignation or removal.

Information regarding the executive officers and directors of Seacoast and SNB is contained in documents filed by Seacoast with the SEC and incorporated by reference into this proxy statement/prospectus, including Seacoast’s Annual Report on Form 10-K for the year ended December 31, 2020 and its definitive proxy statement on Schedule 14A for its 2021 annual meeting, filed with the SEC on March 1, 2021 and April 9, 2021 (as amended), respectively. See “Where You Can Find More Information” and “Documents Incorporated by Reference.”

Interests of Legacy Directors and Executive Officers in the Merger

In the merger, the directors and executive officers of Legacy will receive the same merger consideration for their Legacy shares as the other Legacy shareholders. In considering the recommendation of the Legacy board of directors that you vote to approve the merger agreement, you should be aware that some of the executive officers and directors of Legacy may have interests in the merger and may have arrangements, as described below, that may be considered to be different from, or in addition to, those of Legacy shareholders generally. The Legacy board of directors was aware of these interests and considered them, among other matters, in reaching its decision to adopt and approve the merger agreement and to recommend that Legacy shareholders vote in favor of approving the merger agreement. See “The Merger — Background of the Merger” and “The Merger — Legacy’s Reasons for the Merger and Recommendations of the Legacy Board of Directors.” Legacy’s shareholders should take these interests into account in deciding whether to vote

TABLE OF CONTENTS

“FOR” the proposal to adopt the merger agreement. These interests are described in more detail below, and certain of them are quantified in the narrative below.

Treatment of Legacy Equity Awards

Acceleration of Benefits and Termination of Deferred Compensation Arrangements

Legacy has adopted Supplemental Executive Retirement Plans for each of Dennis Bedley, Bradley Meredith, and Marcia Snyder. As a result of the merger, all benefits provided for under such deferred compensation plans will vest. Accordingly, immediately prior to the effective time and conditioned upon consummation of the merger, the Supplemental Executive Retirement Plans will be terminated and each of Dennis Bedley, Bradley Meredith, and Marcia Snyder will be entitled to receive a lump-sum payment in connection with such termination. Legacy estimates that the pre-tax amount of these payments will be $733,884, $399,048, and $473,355, respectively.

Meredith Change in Control Payment

Bradley Meredith, current Executive Vice President and Chief Financial Officer of Legacy, has an existing employment agreement with Legacy. As part of this employment agreement with Legacy, Legacy agreed to provide payments to Mr. Meredith upon certain events relating to a change-in-control of Legacy. Accordingly, immediately prior to the effective time and conditioned upon consummation of the merger, Mr. Meredith’s existing employment agreement will be terminated and he shall be entitled to receive an estimated pre-tax change-in-control payment of $306,000.

Bedley Employment Agreement

Dennis Bedley, current Chairman and Chief Executive Officer of Legacy, has entered into an employment agreement with Seacoast and SNB effective upon the closing of the merger. The agreement provides for the termination of Mr. Bedley’s existing employment agreement with Legacy, entitling Mr. Bedley to receive a payment in the amount of $425,000, the full amount that Mr. Bedley would be entitled to under his existing employment agreement with Legacy in connection with the merger, as consideration for such termination. The employment agreement with Seacoast and SNB also provides for, among other things, Mr. Bedley’s employment with SNB as Senior Vice President, Broward County Market President from the effective time of the merger through the third anniversary of the effective date. Mr. Bedley will receive an annual base salary of

TABLE OF CONTENTS

$275,000 during the term of the agreement and is eligible to receive annual bonus compensation under SNB’s annual incentive program; provided, however, that such bonus compensation shall not be less than $150,000 for each of the 2021, 2022, and 2023 bonus years. Mr. Bedley is also entitled to an automobile allowance of $650 per month.

If Mr. Bedley’s employment is terminated by Seacoast during the term of the agreement without cause or by Mr. Bedley for good reason, Mr. Bedley is entitled to payment of all earned and unpaid salaries, payment in lieu of any unused vacation time, and an amount equal to twelve (12) months of his annual base salary to be paid in equal monthly installments over a twelve (12) month period. Payment of any such severance payment is conditioned upon the execution of a release by Mr. Bedley releasing Seacoast and SNB from certain claims.

For a period beginning on the effective date of the merger and ending on the later of the second anniversary of the effective date or one year following termination of Mr. Bedley’s employment with Seacoast, Mr. Bedley has agreed not to attempt to compete with SNB within the restricted area (as defined in the employment agreement) or to solicit employees or customers of SNB.

Snyder Employment Agreement

Marcia Snyder, current Chief Lending Officer and Chief Operations Officer of Legacy, has entered into an employment agreement with Seacoast and SNB effective upon the closing of the merger. The agreement provides for the termination of Ms. Snyder’s existing employment agreement with Legacy, entitling Ms. Snyder to receive a payment in the amount of $365,000 as consideration for such termination. The employment agreement with Seacoast and SNB also provides for, among other things, Ms. Snyder’s employment with Seacoast as a Senior Vice President from the effective time of the merger through the second anniversary of the effective date. Ms. Snyder will receive an annual base salary of $250,000 during the term of the agreement and is eligible to receive annual bonus compensation under SNB’s existing Commercial Lending Incentive Plan; provided, however, that such bonus compensation shall not be less than $115,000 for each of the 2021 and 2022 bonus years.

If Ms. Snyder’s employment is terminated by Seacoast during the term of the agreement without cause or by Ms. Snyder for good reason, Ms. Snyder is entitled to payment of all earned and unpaid salaries, payment in lieu of any unused vacation time, and an amount equal to twelve (12) months of Ms. Snyder’s annual base salary to be paid in equal monthly installments over a twelve (12) month period. Payment of any such severance payment is conditioned upon the execution of a release by Ms. Snyder releasing Seacoast and SNB from certain claims.

For a period beginning on the effective date of the merger and ending on the later of the second anniversary of the effective date or one year following termination of Ms. Snyder’s employment with Seacoast, Ms. Snyder has agreed not to attempt to compete with SNB within the restricted area (as defined in the employment agreement) or to solicit employees or customers of SNB.

permitted by Legacy’s organizational documents and the FFIC. Seacoast also has agreed, for a period of no less than six years after the effective time of the merger, to provide coverage to present and former directors and officers of Legacy pursuant to Legacy’s existing directors’ and officers’ liability insurance. This insurance policy may be substituted, but must contain at least the same coverage and amounts, and contain terms no less advantageous than the coverage currently provided by Legacy. In no event shall Seacoast be required to expend for the tail insurance a premium amount in excess of 150% of the annual premiums paid by Legacy for its directors’ and officers’ liability insurance in effect as of the date of the merger agreement.

Employees classified as non-exempt employees will be entitled to receive a severance payment equal to one (1) week’s pay for each year of employment with Legacy as of the date of such termination, with a two (2) week minimum and a ten (10) week maximum.

TABLE OF CONTENTS

THE MERGER AGREEMENT

The following is a summary of the material provisions of the merger agreement. This summary is qualified in its entirety by reference to the merger agreement, a copy of which is included as Appendix A to this proxy statement/prospectus and is incorporated herein by reference. You should read the merger agreement carefully and in its entirety, as it is the legal document governing the merger.

The Merger

The boards of directors of Seacoast and Legacy have each approved and adopted the merger agreement, which provides for the merger of Legacy with and into SNB, with SNB surviving the merger as the surviving bank in the merger. Each share of Legacy common stock outstanding immediately prior to the effective time of the merger (excluding shares held by Legacy, SNB, Seacoast and their wholly-owned subsidiaries, and dissenting shares described below) shall be converted into the right to receive the merger consideration as described further below. Each share of Seacoast common stock outstanding immediately prior to the effective time of the merger will remain outstanding as one share of Seacoast common stock and will not be affected by the merger.

All shares of Seacoast common stock received by Legacy shareholders in the merger will be freely tradable, except that shares of Seacoast common stock received by persons who become affiliates of Seacoast for purposes of Rule 144 under the Securities Act may be resold by them only in transactions permitted by Rule 144, or as otherwise permitted under the Securities Act.

Closing and Effective Time of the Merger

The parties will use their reasonable best efforts to cause the effective time of the merger to occur on a mutually agreeable date following the date on which satisfaction or waiver of the closing conditions set forth in the merger agreement has occurred.

We currently expect that the merger will be completed in the third quarter of 2021, subject to the approval of the merger agreement by Legacy shareholders and certain bank regulators and subject to other conditions as described further in this proxy statement/prospectus. However, completion of the merger could be delayed if there is a delay in satisfying any other conditions to the merger. No assurance is made as to whether, or when, Seacoast and Legacy will complete the merger. See “The Merger Agreement — Conditions to Completion of the Merger.”

Merger Consideration

Under the terms of the merger agreement, each share of Legacy common stock outstanding immediately prior to the effective time of the merger (excluding certain shares held by Seacoast, Legacy, SNB and their wholly-owned subsidiaries and dissenting shares described below) will be converted into the right to receive 0.1703, which we refer to as the exchange ratio, of a share of Seacoast common stock (which we refer to as the “merger consideration,” and also referred to in an aggregate consideration amount, which includes the substitute stock options certain Legacy shareholders may receive, as the “aggregate merger consideration”). Please see “The Merger Agreement — Consideration” for more information. If Legacy’s consolidated tangible shareholders’ equity as of the close of business on the fifth business day prior to the closing date is less than $58.2 million (less the after-tax impact of permitted expenses) and general allowance for loan and lease losses is less than 0.75% of total loans and leases outstanding (excluding PPP loans), Seacoast shall have the option to adjust the merger consideration downward by an amount that equals the difference between $58.2 million (less the after-tax impact of permitted expenses) and Legacy’s consolidated tangible shareholders’ equity.

For each fractional share that would otherwise be issued, Seacoast will pay cash (without interest) in an amount equal to such fractional part of a share of Seacoast common stock multiplied by the average daily volume weighted average price of Seacoast common stock on the NASDAQ Global Select Market for the twenty trading days ending on the trading day immediately prior to the determination date, less any applicable withholding taxes. The “determination date” is defined in the merger agreement as the later of the date on which the last required consent obtained without regard to any requisite waiting period or the date on which

TABLE OF CONTENTS

Legacy shareholder approval is obtained. No holder will be entitled to dividends, voting rights or any other rights as a shareholder in respect of any fractional share.

In addition, each share of Legacy common stock issued and outstanding and held by a shareholder who has given notice of its intention to assert the right to dissent in accordance Section 658.44 of the FFIC and Sections 607.1301 through 607.1340 of the FBCA and who has not voted in favor of the merger agreement and has otherwise complied with the provisions of Florida law will not be converted into the right to receive the merger consideration (which we refer to as “dissenting shares”). Instead, dissenting shares will become the right to receive whatever consideration may be determined to be due to such dissenting shareholder under Section 658.44 of the FFIC and Sections 607.1301 through 607.1340 of the FBCA. If any dissenting shareholder fails to perfect or effectively withdraws its demand for appraisal or otherwise loses its rights as a dissenting shareholder under Section 658.44 and Sections 607.1301 through 607.1340 of the FBCA, dissenting shares held by such dissenting shareholder will be treated as though such dissenting shares had been converted into and exchangeable, at the effective time, for the right to receive the merger consideration (without interest). See “The Merger — Dissenters’ Rights for Legacy Shareholders.”

If the number of shares of Seacoast common stock or Legacy common stock issued and outstanding prior to the effective time of the merger is increased or decreased as a result of a stock split, stock combination, stock dividend or similar transaction with respect to the Seacoast common stock or Legacy common stock, then the merger consideration shall be proportionately adjusted as necessary to preserve the relative economic benefit to the parties.

Based upon the closing sale price of the Seacoast common stock on the NASDAQ Global Select Market of $ on , 2021, the last practicable trading date prior to the printing of this proxy statement/prospectus, each share of Legacy common stock will be entitled to be exchanged for total merger consideration with a value equal to approximately $ per share.

The value of the shares of Seacoast common stock to be issued to Legacy shareholders in the merger will fluctuate between now and the closing date of the merger. We make no assurances as to whether or when the merger will be completed, and you are advised to obtain current sale prices for the Seacoast common stock. See “Risk Factors — Because the sale price of the Seacoast common stock will fluctuate, you cannot be sure of the value of the stock consideration that you will receive in the merger until the closing.”

Treatment of Legacy Equity Awards

TABLE OF CONTENTS

Exchange Procedures

Seacoast has appointed as the exchange agent under the merger agreement its exchange agent, Continental Stock Transfer and Trust Company. The merger agreement requires Seacoast to cause the exchange agent as promptly as practicable after the effective time and within five business days, to send to each former holder of shares of Legacy common stock, including holders of Legacy equity awards who received Legacy common stock in accordance with the exercise of such Legacy equity awards prior to the effective time, but excluding the holders, if any, of dissenting shares, transmittal materials for use in exchanging such holder’s Legacy certificates for the merger consideration. Upon surrender to the transfer agent of its certificates, a holder will be entitled to receive the merger consideration and any cash in lieu of a fractional share of Seacoast common stock to be issued.

Subject to law, following the surrender of any certificate or book-entry shares, there shall be issued and/or paid to the holder of the certificates representing whole shares of Seacoast common stock issued in exchange for Legacy common stock, without interest: (i) at the time of such surrender, the dividends or other distributions with a record date after the effective time of the merger payable with respect to the whole shares of Seacoast common stock and not paid; and (ii) at the appropriate payment date, the dividends or other distributions payable with respect to shares of Seacoast common stock with a record date after the effective time of the merger and with a payment date subsequent to surrender.

After the effective time of the merger, there will be no registration of transfers on the stock transfer books of Legacy of Legacy common stock.

Organizational Documents of Surviving Bank; Directors and Officers

The organizational documents of SNB in effect immediately prior to the effective time of the merger shall be the organizational documents of the surviving bank after the effective time of the merger. The directors and officers of SNB immediately prior to the effective time of the merger shall continue as the directors and officers of the surviving bank following the effective time of the merger.

Conduct of Business Pending the Merger

Each of the parties have agreed not to take any action that would adversely affect or delay (i) the approval of the merger agreement by Legacy shareholders, (ii) the receipt of all required regulatory consents or (iii) the ability of either party to perform its respective covenants and agreements under the merger agreement or to consummate the transactions contemplated by the merger agreement.

Each of Seacoast and Legacy have agreed to use all reasonable best efforts to take, or cause to be taken, in good faith, all actions, and to do, or cause to be done, all things necessary, proper or desirable, or advisable under applicable laws, to permit consummation of the merger as promptly as practicable and otherwise to enable the consummation of the transactions contemplated by the merger agreement.

Legacy has also agreed that, except as expressly contemplated or permitted by the merger agreement, it will not, without the prior written consent of Seacoast’s chief executive officer or chief financial officer (or

Legacy Shareholder Approval

Legacy has agreed to call a meeting of its shareholders as soon as reasonably practicable after the Registration Statement on Form S-4 is declared effective by the SEC for the purpose of obtaining shareholder approval of the merger agreement. Legacy has further agreed to use its reasonable best efforts to cause the shareholder meeting to occur as soon as reasonably practicable.

Regulatory Matters

This proxy statement/prospectus forms part of a Registration Statement on Form S-4 which Seacoast has filed with the SEC. Seacoast has agreed to use all reasonable efforts to cause the Registration Statement to be declared effective by the SEC as promptly as reasonably practicable after filing.

Each of Seacoast and Legacy has agreed to use all reasonable best efforts to obtain all permits required by the securities laws, including state securities law or “blue sky” permits, necessary to carry out the transactions contemplated by the merger agreement and each of Seacoast and Legacy has agreed to furnish all information concerning it and the holders of its capital stock as may be reasonably requested in connection with any such action.

Seacoast and Legacy have agreed to use all respective reasonable best efforts to take, or cause to be taken, in good faith, all actions and to do, or cause to be done, all things necessary, proper or desirable, or advisable under applicable laws, to permit the consummation of the merger as promptly as practicable.

Seacoast and Legacy have agreed to consult with each other with respect to the obtaining of all regulatory consents and other material consents advisable to consummate the transactions contemplated by the merger agreement, and each party has agreed to keep the other apprised of the status of material matters relating to the completion of the transactions contemplated by the merger agreement.

Seacoast and Legacy have agreed to promptly furnish to each other copies of applications filed with all governmental authorities and copies of written communications received by such party from any governmental authorities with respect to the transactions contemplated by the merger agreement. Additionally, each of Seacoast and Legacy has agreed to cooperate fully with and furnish information to the other party, and obtain all consents of, and give all notices to and making all filings with, all governmental authorities and other third parties that may be or become necessary for the performance of its obligations under the merger agreement and the consummation of the other transactions contemplated by the merger agreement.

NASDAQ Listing

Seacoast has agreed to cause the shares of Seacoast common stock to be issued in connection with the merger to be approved for listing on the NASDAQ Global Select Market, subject to official notice of issuance, prior to the effective time of the merger.

Employee Matters

Following the effective time of the merger, Seacoast has agreed to maintain employee benefit plans and compensation opportunities for full-time active employees of Legacy on the closing date of the merger (referred to below as “covered employees”) that provide employee benefits and compensation opportunities which, in the aggregate, are substantially comparable to the employee benefits and compensation opportunities that are available on a uniform and non-discriminatory basis to similarly situated employees of Seacoast or its subsidiaries (provided that in no event are covered employees eligible to participate in any closed or frozen plan of Seacoast or its subsidiaries and provided further that in no event is Seacoast required to take into account any retention arrangements or equity compensation when determining whether employee benefits are substantially comparable). Seacoast will give the covered employees full credit for their prior service with Legacy for purposes of eligibility (including initial participation and eligibility for current benefits) and vesting under any qualified or non-qualified employee benefit plan maintained by Seacoast in which covered employees may be eligible to participate and for all purposes under any welfare benefit plans, vacation plans, and similar arrangements maintained by Seacoast.

TABLE OF CONTENTS

With respect to any Seacoast health, dental, vision or other welfare plan in which any covered employee is eligible to participate, for the plan year in which such covered employee is first eligible to participate, Seacoast or its applicable subsidiary must use its commercially reasonable best efforts to (i) cause any pre-existing condition limitations or eligibility waiting periods under such plan to be waived with respect to the covered employee to the extent the condition was, or would have been, covered under the Legacy benefit plan in which the covered employee participated immediately prior to the effective time of the merger and (ii) recognize any health, dental, vision or other welfare expenses incurred by the covered employee in the year that includes the closing date of the merger for purposes of any applicable deductible and annual out-of-pocket expense requirements.

If, within 6 months after the effective time of the merger, any covered employee is terminated by Seacoast or its subsidiaries other than “for cause” or as a result of a death, disability or unsatisfactory job performance, then Seacoast will pay severance to the covered employee in an amount set forth in its severance policies. Any severance to which a covered employee may be entitled in connection with a termination occurring more than 6 months after the effective time of the merger will be as set forth in its severance policies.

Promptly after the effective time of the merger, Seacoast must file with the SEC a registration statement on Form S-8 with respect to the Seacoast common stock that may be issued with respect to the substitute Seacoast stock options and must use commercially reasonable efforts to maintain the effectiveness of such registration statement for so long as a substitute Seacoast stock option remains outstanding.

Indemnification and Directors’ and Officers’ Insurance

From and after the effective time of the merger, Seacoast has agreed to indemnify, defend and hold harmless the present and former directors and officers of Legacy against any liability, judgments, fines and amounts paid in settlement in connection with any threatened or actual claim, action, suit, proceeding or investigation arising in whole or in part out of, or pertaining to (i) the fact that such person is or was a director, officer or employee of Legacy, its subsidiaries or any of its predecessors or (ii) the merger agreement or any of the transactions contemplated by the merger agreement, whether asserted or arising before or after the effective time, to the same extent permitted by law and as such persons are indemnified or have the right to advancement of expenses pursuant to Legacy’s organizational documents and the FFIC. All existing rights to indemnification and all existing limitations on liability existing in favor of the directors, officers and employees of Legacy as provided in its organizational documents shall survive the merger and remain in full force and effect and shall be honored by Seacoast.

Seacoast also has agreed, for a period of no less than six years following the effective time of the merger, to provide directors’ and officers’ liability insurance to reimburse present and former officers and directors of Legacy or its subsidiaries with respect to claims against such directors and officers arising from facts or events occurring before the effective time of the merger. Such insurance must contain at least the same coverage and amounts, and contain terms and conditions no less advantageous to the indemnified party as the coverage provided by Legacy. In no event shall Seacoast be required to expend for the tail insurance a premium amount in excess of 150% of the annual premiums paid by Legacy for its directors’ and officers’ liability insurance in effect as of the date of the merger agreement.

Third Party Proposals

Legacy has agreed that it will not, and will cause its directors, officers, and employees, any investment banker, financial advisor, attorney, accountant, consultant, agent or other representative and its affiliates not to: (i) initiate, solicit, encourage or knowingly facilitate inquiries or proposals with respect to, (ii) engage or participate in any negotiations concerning, or (iii) provide any confidential or nonpublic information or data to, or have or participate in any discussions with, any person related to any acquisition proposal. “Acquisition proposal” means, other than the transactions contemplated by the merger agreement, any offer, proposal or inquiry relating to, or any third party indication of interest in, (i) any acquisition or purchase, direct or indirect, of 25% or more of the consolidated assets of Legacy or 25% or more of any class of equity or voting securities of Legacy, (ii) any tender offer (including a self-tender offer) or exchange offer that, if consummated, would result in or would reasonably be expected to result in such third party beneficially owning 25% or more of any class of equity or voting securities of Legacy, (iii) a merger, consolidation, share exchange, business combination, reorganization, recapitalization, liquidation, dissolution or other similar transaction involving

TABLE OF CONTENTS

Legacy, or (iv) any other transaction the consummation of which could reasonably be expected to impede, interfere with, prevent or materially delay the merger or that could reasonably be expected to dilute materially the benefits to Seacoast of the transactions contemplated by the merger agreement.

However, the merger agreement provides that if Legacy receives an unsolicited bona fide acquisition proposal that does not violate the “no shop” provisions in the merger agreement and Legacy’s board of directors concludes in good faith that there is a reasonable likelihood that such proposal constitutes or is reasonably likely to result in a superior proposal (as defined below), then Legacy may, and may permit its officers and representatives to, furnish or cause to be furnished non-public information or data and participate in negotiations or discussions to the extent the Legacy board of directors concludes in good faith (and based on the written advice of its outside legal counsel) that failure to take such actions would result in a breach of its fiduciary duties under applicable law. Prior to providing any non-public information, Legacy shall have entered into a confidentiality agreement with such third party with terms no less favorable to Legacy than the confidentiality agreement entered into by Legacy and Seacoast prior to the execution of the merger agreement. Legacy must promptly advise Seacoast within two (2) business days following receipt or notice of any acquisition proposal and the substance of such proposal (including the identity of the person making such proposal) and must keep Seacoast apprised of any related developments, discussions and negotiations on a current basis. A “superior proposal” means any bona fide, unsolicited, written “acquisition proposal” for at least a majority of the outstanding shares of Legacy common stock on terms that the Legacy board of directors concludes in good faith, (i) after receiving the written advice of its financial advisor, (ii) after taking into account the likelihood of consummation of such proposal on the terms set forth in the proposal (as compared to, and with due regard for, the terms of the merger agreement) and (iii) after taking into account all legal (with the written advice of outside counsel), financial (including the financing terms of any such proposal), regulatory and other aspects of such proposal and any other relevant factors permitted under applicable law, is more favorable to the Legacy shareholders from a financial point of view than the merger (including the terms, if any, proposed by Seacoast to amend or modify the terms of the transactions contemplated by the merger agreement).

The merger agreement generally prohibits Legacy’s board of directors from making a change in recommendation (i.e., from withdrawing or modifying in a manner adverse to Seacoast the recommendation of the Legacy board of directors set forth in this proxy statement/prospectus that the Legacy shareholders vote to approve the merger agreement, or from making or causing to be made any third party or public communication proposing or announcing an intention to withdraw or modify in a manner adverse to Seacoast such recommendation). At any time prior to the approval of the merger agreement by the Legacy shareholders, however, the Legacy board of directors may effect a change in recommendation if the Legacy board of directors concludes in good faith (and based upon the written advice of its outside counsel and after consultation with its financial advisor and outside legal counsel) that an acquisition proposal constitutes or would reasonably be expected to constitute a superior proposal and that the failure to accept such superior proposal would reasonably be expected to result in a breach of its fiduciary obligations under applicable laws, and terminate the merger agreement and enter into a definitive agreement with respect to such superior proposal.

The Legacy board of directors may not make a change in recommendation and terminate the merger agreement with respect to an acquisition proposal, unless: (i) Legacy has not breached any of the provisions of the merger agreement relating to third party acquisition proposals in any respect; (ii) the Legacy board of directors determines in good faith (after consultation with outside legal counsel and its financial advisors) that such superior proposal has been made and has not been withdrawn and continues to be or is reasonably expected to continue to be a superior proposal (after taking into account all adjustments to the terms of the merger agreement offered by Seacoast); (iii) Legacy has given Seacoast at least 4 business days’ prior written notice of its intention to take such action (which notice shall specify the material terms and conditions of any superior proposal including the identity of the person making such superior proposal) and has contemporaneously provided an unredacted copy of the relevant proposed transaction agreements with the person making such superior proposal; and (iv) before effecting such change in recommendation, Legacy has negotiated, and has caused its representatives to negotiate, in good faith with Seacoast during the notice period (to the extent Seacoast wishes to negotiate) to enable Seacoast to revise the terms of the merger agreement so that such superior proposal no longer constitutes a superior proposal. In the event of any

TABLE OF CONTENTS

material change to the terms of a superior proposal, Legacy shall be required to deliver a new written notice to Seacoast and the four business day negotiation period with Seacoast shall have recommenced.

If the Legacy board of directors makes a change in recommendation, if Legacy terminates the merger agreement to enter into an agreement with respect to a superior proposal, or if Legacy’s shareholders do not approve the merger agreement and Legacy enters into an agreement with respect to an acquisition proposal within twelve months from the date the merger agreement is terminated, Legacy could be required to pay Seacoast a termination fee of $4,600,000 in cash.

Legacy shall take any action Seacoast may reasonably request prior to the effective time of the merger to facilitate the combination of the operations of Legacy with SNB.

COMPARISON OF SHAREHOLDERS’ RIGHTS

Seacoast and Legacy are each incorporated under the laws of the State of Florida and, accordingly, the rights of their shareholders are governed by Florida law and their respective articles of incorporation and bylaws. After the merger, each share of Legacy common stock issued and outstanding immediately prior to the effective time of the merger will be converted into the right to receive the merger consideration, which will consist of Seacoast common stock. As a result, the rights of former shareholders of Legacy who receive shares of Seacoast common stock in the merger will be determined by reference to Seacoast’s articles of incorporation and bylaws and Florida law. Set forth below is a description of the material differences between the rights of Legacy shareholders and Seacoast shareholders. The following summary does not include a complete description of all differences between the rights of Legacy shareholders and Seacoast shareholders, nor does it include a complete discussion of the respective rights of Legacy shareholders and Seacoast shareholders.

	Under the FBCA, a corporation may make a distribution, unless after giving effect to the distribution: • The corporation would not be able to pay its debts as they come due in the usual course of business; or • The corporation’s assets would be less than the sum of its total liabilities plus (unless the articles of incorporation provide otherwise) the amount that would be needed, if the corporation were to be dissolved at the time of the distribution, to satisfy the preferential rights upon dissolution of shareholders whose preferential rights are superior to those receiving the distribution. In addition, under Federal Reserve policy adopted in 2009, a bank holding company should consult with the Federal Reserve and eliminate, defer or significantly reduce its dividends if: • its net income available to shareholders for the past four quarters, net of dividends previously paid during that period, is not sufficient to fully fund the dividends; • its prospective rate of earnings retention is not consistent with its capital needs and overall current and prospective financial condition; or • it will not meet, or is in danger of not meeting, its minimum regulatory capital adequacy ratios.
Number of Directors	Legacy’s articles of incorporation provide that the number of directors serving on Legacy’s board of directors should not be fewer than five and not more than twenty-five. A majority of the full board of directors may, at any time during the years following the annual meeting of shareholders on which such action has been authorized, increase the number of directors by not more than two per year and appoint persons to fill resulting vacancies. Legacy’s bylaws provide that the number of directors may be increased from time to time by action of the board of directors. The board of directors of Legacy currently has eight directors.	Seacoast’s bylaws provide that the number of directors serving on the Seacoast board of directors shall be such number as determined from time to time by a vote of 662∕3% of the whole board of directors and a majority of the Continuing Directors (director who either (i) was first elected as a director of the company prior to March 1, 2002 or (ii) was designated as a Continuing Directors by a majority vote of the Continuing Directors), but in no event shall be fewer than three directors nor greater than fourteen directors (exclusive of the directors to be elected by the holders of one or more series of preferred stock voting separately as a class). There are currently eleven directors serving on the Seacoast board of directors. The Seacoast board of directors is divided into three classes, with the members of each class of directors serving staggered three-year terms and with approximately one-third of the directors being elected annually. As a result, it would take a dissident shareholder or shareholder group at least two annual meeting of shareholders to replace a majority of the directors of Seacoast. Each director holds office for

		the term for which he or she is elected and until his or her successor is elected and qualified, subject to such directors’ death, resignation or removal.
Election of Directors	Under the FBCA, unless otherwise provided in the articles of incorporation, directors are elected by a plurality of the votes cast by the holders of the shares entitled to vote in an election of directors the annual meeting at which a quorum is present. Legacy’s articles of incorporation do not otherwise provide for the vote required to elect directors.	Seacoast directors are similarly elected in accordance with FBCA and its articles of incorporation do not otherwise provide for the vote required to elect directors. However, notwithstanding the plurality standard, in an uncontested election for directors, Seacoast’s Corporate Governance Guidelines provide that if any director nominee receives a greater number of votes “withheld” from his or her election than votes “for” such election, then the director will promptly tender his or her resignation to the board of directors following certification of the shareholder vote, with such resignation to be effective upon acceptance by the board of directors. The Compensation and Governance Committee would then review and make a recommendation to the board of directors as to whether the board should accept the resignation, and the board of directors would ultimately decide whether to accept the resignation.
Removal of Directors	Florida law allows shareholders to remove one or more directors from the board of directors with or without cause if the number of votes cast to remove the director exceeds the number of votes cast not to remove the director. A director may be removed by the shareholders only at a meeting of shareholders called for the purpose of removing the director, and the meeting notice must state that the removal of the director is the purpose, or one of the purposes, of the meeting. Directors may also be removed by judicial proceedings.	Seacoast’s bylaws provide that directors may be removed only for cause upon the affirmative vote of (1) 662∕3% of all shares of common stock entitled to vote and (2) holders of a majority of the outstanding common stock that are not beneficially owned or controlled, directly or indirectly, by any person (1) who is the beneficial owner of 5% or more of the common stock or (2) who is an affiliate of Seacoast and at any time within the past five years was the beneficial owner of 5% or more of Seacoast’s then outstanding common stock (“Independent Majority of Shareholders”) at a shareholders’ meeting duly called and held for that purpose upon not less than 30 days’ prior written notice.
Vacancies on the Board of Directors	Legacy’s articles of incorporation provide that any vacancy on the board of directors, including a vacancy resulting from an increase in the number of directors, may be filled by appointment by a majority of the directors then in office, even if less than a quorum, or by a sole remaining director. Florida law also allows a vacancy to be filled by the shareholders.	Seacoast’s bylaws provide that vacancies in the Seacoast’s board of directors may be filled by the affirmative vote of (1) 662∕3% of all directors and (2) majority of the Continuing Directors, even if less than a quorum exists, or if no directors remain, by the affirmative vote of not less than 662∕3% of all shares of common stock entitled to vote and an Independent Majority of Shareholders.
Action by Written Consent	Legacy’s bylaws provide that any action required or permitted by law to be taken at a board of directors’ meeting or committee meeting may be taken without a meeting if action is taken by all members of the board or the committee. The action must be evidenced by a written consent describing the action taken and signed by each director or committee member. Action taken shall be effective when received	Seacoast’s articles of incorporation provide that no action may be taken by written consent except as may be provided in the designation of the preferences, limitations and relative rights of any series of Seacoast’s preferred stock.

The board of directors must recommend the amendment to the shareholders, unless the board of directors determines that, because of a conflict of interest or other special circumstances, it should make no	Seacoast’s articles of incorporation have similar amendment provisions, except that the affirmative vote of (1) 662∕3% of all of shares outstanding and entitled to vote, voting as classes, if applicable, and (2) an Independent Majority of Shareholders will be required to approve any change of Articles VI (“Board of Directors”), VII (“Provisions Relating to Business Combinations”), IX (“Shareholder Proposals”) and X (“Amendment of articles of incorporation”) of the articles of incorporation.

TABLE OF CONTENTS

DESCRIPTION OF SEACOAST CAPITAL STOCK

Common Stock

General

The following description of shares of Seacoast’s common stock, par value $0.10 per share, is a summary only and is subject to applicable provisions of the FCBA and to Seacoast’s amended and restated articles of incorporation, as amended, and its amended and restated bylaws. Seacoast’s articles of incorporation provide that it may issue up to 120 million shares of common stock, par value of $0.10 per share. Seacoast common stock is listed on the NASDAQ Global Select Market under the symbol “SBCF.”

Voting Rights

Each outstanding share of Seacoast’s common stock entitles the holder to one vote on all matters submitted to a vote of shareholders, including the election of directors. The holders of Seacoast common stock possess exclusive voting power, except as otherwise provided by law or by articles of amendment establishing any series of Seacoast preferred stock.

There is no cumulative voting in the election of directors, which means that the holders of a plurality of Seacoast’s outstanding shares of common stock can elect all of the directors then standing for election. When a quorum is present at any meeting, questions brought before the meeting will be decided by the vote of the holders of a majority of the shares present and voting on such matter, whether in person or by proxy, except when the meeting concerns matters requiring the vote of the holders of a majority of all outstanding shares under applicable Florida law. Seacoast’s articles of incorporation provide certain anti-takeover provisions that require super-majority votes, which may limit shareholders’ rights to effect a change in control as described under the section below entitled “Anti-Takeover Effects of Certain articles of incorporation Provisions.”

Dividends, Liquidation and Other Rights

Holders of shares of common stock are entitled to receive dividends only when, as and if approved by Seacoast’s board of directors from funds legally available for the payment of dividends. Seacoast’s shareholders are entitled to share ratably in its assets legally available for distribution to its shareholders in the event of Seacoast’s liquidation, dissolution or winding up, voluntarily or involuntarily, after payment of, or adequate provision for, all of our known debts and liabilities and of any preferences of any series of our preferred stock that may be outstanding in the future. These rights are subject to the preferential rights of any series of Seacoast’s preferred stock that may then be outstanding.

Holders of shares of Seacoast common stock have no preference, conversion, exchange, sinking fund or redemption rights and have no preemptive rights to subscribe for any of our securities. Seacoast’s board of directors, under its articles of incorporation, may issue additional shares of its common stock or rights to purchase shares of its common stock without shareholder approval.

Restrictions on Ownership

The Bank Holding Company Act requires any “bank holding company,” as defined in the Bank Holding Company Act, to obtain the approval of the Federal Reserve prior to the acquisition of 5% or more of our common shares. Any person, other than a bank holding company, is required to obtain prior approval of the Federal Reserve to acquire 10% or more of our common shares under the Change in Bank Control Act. Any holder of 25% or more of our common shares, or a holder of 5% or more if such holder otherwise exercises a “controlling influence” over us, is subject to regulation as a bank holding company under the Bank Holding Company Act.

Certain provisions included in our amended and restated articles of incorporation and bylaws, as described further below, as well as certain provisions of the Florida Business Corporation Act and federal law, may discourage, delay or prevent potential acquisitions of control of us, particularly when attempted in a transaction that is not negotiated directly with, and approved by, our board of directors, despite possible benefits to our shareholders. These provisions are more fully described in the documents and reports filed

TABLE OF CONTENTS

with the SEC pursuant to Sections 13(a), 13(c), 14 or 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference into this prospectus.

Preferred Stock

General

Seacoast is authorized to issue 4 million shares of preferred stock, 2,000 shares of which have been designated as Series A Preferred Stock, and 50,000 of which have been designated as Series B Preferred Stock. On December 31, 2013, Seacoast redeemed in full all 2,000 shares of Series A Preferred Stock then issued and outstanding. Such Series A Preferred Stock was originally issued to the U.S. Treasury Department under the Capital Purchase Program and subsequently auctioned to private investors. No shares of Series A or Series B Preferred Stock are issued and outstanding as of the date of this proxy statement/prospectus.

Under Seacoast’s amended and restated articles of incorporation, its board of directors is authorized, without shareholder approval, to adopt resolutions providing for the issuance of up to 4 million shares of preferred stock, par value $0.10 per share, in one or more series. Seacoast’s board of directors may fix the voting powers, designations, preferences, rights, qualifications, limitations and restrictions of each series of preferred stock. A series of preferred stock upon issuance will have preference over Seacoast common stock with respect to the payment of dividends and the distribution of assets in the event of the liquidation or dissolution of Seacoast. The relative rights, preferences and limitations that Seacoast’s board of directors has the authority to determine as to any such series of such stock include, among other things, dividend rights, voting rights, conversion rights, redemption rights, and liquidation preferences. Because Seacoast’s board of directors has the power to establish the relative rights, preferences and limitations of each series of such stock, it may afford to the holders of any such series, preferences and rights senior to the rights of the holders of the shares of common stock, as well as the shares of preferred stock to be issued in the reclassification transaction. Although Seacoast’s board of directors has no intention at the present time of doing so, it could cause the issuance of any additional shares of preferred stock that could discourage an acquisition attempt or other transactions that some, or a majority of, the shareholders might believe to be in their best interests or in which the shareholders might receive a premium for their shares of common stock over the market price of such shares.

Transfer Agent and Registrar

The transfer agent and registrar for Seacoast common stock is Continental Stock Transfer and Trust Company.

Anti-Takeover Effects of Certain Articles of Incorporation Provisions

Seacoast’s articles of incorporation contain certain provisions that make it more difficult to acquire control of it by means of a tender offer, open market purchase, a proxy fight or otherwise. These provisions are designed to encourage persons seeking to acquire control of Seacoast to negotiate with its directors. Seacoast believes that, as a general rule, the interests of its shareholders would be best served if any change in control results from negotiations with its directors.

Seacoast’s articles of incorporation provide for a classified board to which approximately one-third of its board of directors is elected each year at its annual meeting of shareholders. Accordingly, Seacoast’s directors serve three-year terms rather than one-year terms. The classification of Seacoast’s board of directors has the effect of making it more difficult for shareholders to change the composition of its board of directors. At least two annual meetings of shareholders, instead of one, will generally be required to effect a change in a majority of Seacoast’s board of directors. Such a delay may help ensure that its directors, if confronted by a shareholder attempting to force a proxy contest, a tender or exchange offer, or an extraordinary corporate transaction, would have sufficient time to review the proposal as well as any available alternatives to the proposal and to act in what they believe to be the best interests of Seacoast’s shareholders. The classification provisions apply to every election of directors, however, regardless of whether a change in the composition of Seacoast’s board of directors would be beneficial to Seacoast and its shareholders and whether or not a majority of its shareholders believe that such a change would be desirable.

TABLE OF CONTENTS

The classification of Seacoast’s board of directors could also have the effect of discouraging a third party from initiating a proxy contest, making a tender offer or otherwise attempting to obtain control of Seacoast, even though such an attempt might be beneficial to Seacoast and its shareholders. The classification of Seacoast’s board of directors could thus increase the likelihood that incumbent directors will retain their positions. In addition, because the classification of Seacoast’s board of directors may discourage accumulations of large blocks of its stock by purchasers whose objective is to take control of Seacoast and remove a majority of its board of directors, the classification of its board of directors could tend to reduce the likelihood of fluctuations in the market price of its common stock that might result from accumulations of large blocks of its common stock for such a purpose. Accordingly, Seacoast’s shareholders could be deprived of certain opportunities to sell their shares at a higher market price than might otherwise be the case.

Seacoast’s articles of incorporation require the affirmative vote of the holders of not less than two-thirds of all the shares of its stock outstanding and entitled to vote generally in the election of directors in addition to the votes required by law or elsewhere in the articles of incorporation, the bylaws or otherwise, to approve: (a) any sale, lease, transfer, purchase and assumption of all or substantially all of its consolidated assets and/or liabilities, (b) any merger, consolidation, share exchange or similar transaction, or any merger of any significant subsidiary, into or with another person, or (c) any reclassification of securities, recapitalization or similar transaction that has the effect of increasing other than pro rata with the other shareholders, the proportionate amount of shares that is beneficially owned by an Affiliate (as defined in Seacoast’s articles of incorporation). Any business combination described above may instead be approved by the affirmative vote of a majority of all the votes entitled to be cast on the plan of merger if such business combination is approved and recommended to the shareholders by (x) the affirmative vote of two-thirds of Seacoast’s board of directors, and (y) a majority of the Continuing Directors (as defined in Seacoast’s articles of incorporation).

Seacoast’s articles of incorporation also contain additional provisions that may make takeover attempts and other acquisitions of interests in it more difficult where the takeover attempt or other acquisition has not been approved by its board of directors. These provisions include:

•

A requirement that any change to Seacoast’s articles of incorporation relating to the structure of its board of directors, certain anti-takeover provisions and shareholder proposals must be approved by the affirmative vote of holders of two-thirds of the shares outstanding and entitled to vote;

•

A requirement that any change to Seacoast’s bylaws, including any change relating to the number of directors, must be approved by the affirmative vote of either (a) (i) two-thirds of its board of directors, and (ii) a majority of the continuing directors (as defined in Seacoast’s articles of incorporation) or (b) (i) two-thirds of the shares entitled to vote generally in the election of directors and (ii) an Independent Majority of Shareholders. An “Independent Majority of Shareholders” means the majority of the outstanding voting shares that are not beneficially owned or controlled, directly or indirectly by a related party. For these purposes, a “related party” means a beneficial owner of 5% or more of the voting shares, or any person who is an affiliate of Seacoast and at any time within five years was the beneficial owner of 5% or more of Seacoast’s then outstanding shares; provided, however, that this provision shall not include (i) any person who is the beneficial owner of more than 5% of Seacoast’s shares on February 28, 2003, (ii) any plan or trust established for the benefit of Seacoast’s employees generally, or (iii) any subsidiary of Seacoast that holds shares in a fiduciary capacity, whether or not it has the authority to vote or dispose of such securities;

•

A requirement that shareholders may call a meeting of shareholders on a proposed issue or issues only upon the receipt by Seacoast from the holders of 50% of all shares entitled to vote on the proposed issue or issues of signed and dated written demands for the meeting describing the purpose for which it is to be held; and

•

A requirement that a shareholder wishing to submit proposals for a shareholder vote or nominate directors for election comply with certain procedures, including advanced notice requirements.

Seacoast’s articles of incorporation provide that, subject to the rights of any holders of its preferred stock to act by written consent instead of a meeting, shareholder action may be taken only at an annual meeting or special meeting of the shareholders and may not be taken by written consent. The articles of incorporation also include provisions that make it difficult to replace directors. Specifically, directors may be removed only for cause and only upon the affirmative vote at a meeting duly called and held for that purpose

TABLE OF CONTENTS

upon not less than thirty days prior written notice of (i) two-thirds of the shares entitled to vote generally in the election of directors and (ii) an Independent Majority of Shareholders. In addition, any vacancies on the board of directors for any reason, and any newly created directorships resulting from any increase in the number of directors, may be filled only by the board of directors (except if no directors remain on the board, in which case the shareholders may act to fill the vacant board).

Seacoast believes that the power of its board of directors to issue additional authorized but unissued shares of its common stock or preferred stock without further action by its shareholders, unless required by applicable law or the rules of any stock exchange or automated quotation system on which its securities may be listed or traded, will provide Seacoast with increased flexibility in structuring possible future financings and acquisitions and in meeting other needs that might arise. Seacoast’s board of directors could authorize and issue a class or series of stock that could, depending upon the terms of such class or series, delay, defer or prevent a transaction or a change in control that might involve a premium price for holders of Seacoast’s common stock or that its shareholders otherwise consider to be in their best interest.

WHEREAS, this Agreement provides for the acquisition of the Company by SBC pursuant to the merger of the Company with and into SNB (the “Merger”); and

WHEREAS, concurrently with the execution and delivery of this Agreement, as a condition and inducement to Seacoast’s willingness to enter into this Agreement, (i) the Company’s directors, (ii) certain of the Company’s executive officers and (iii) certain beneficial holders of five percent (5%) or more of the outstanding shares of Company Common Stock, have executed and delivered to SBC an agreement in substantially the form of Exhibit A (the “Shareholder Support Agreement”), pursuant to which they have agreed, among other things, subject to the terms of such Shareholder Support Agreement, to vote the shares of Company Common Stock held of record by such Persons or as to which they otherwise have sole voting power to approve and adopt this Agreement and the transactions contemplated hereby, including the Merger.

Certain terms used and not otherwise defined in this Agreement are defined in Section 7.1.

NOW, THEREFORE, in consideration of the above and the mutual warranties, representations, covenants, and agreements set forth herein, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, and intending to be legally bound hereby, the Parties agree as follows:

ARTICLE 1
TRANSACTIONS AND TERMS OF MERGER

1.1 Merger. Subject to the terms and conditions of this Agreement, at the Effective Time (as defined in Section 1.3 herein), the Company shall be merged with and into SNB in accordance with the provisions of 12 U.S.C. Section 215 and with the effect provided in 12 U.S.C. Section 215. SNB shall be the surviving bank (the “Surviving Bank”) resulting from the Merger and the separate existence of the Company shall thereupon cease. SNB shall continue to be governed by the Laws of the United States, and the separate existence of SNB with all of its rights, privileges, immunities, powers and franchises shall continue unaffected by the Merger. All assets of the Company and the Surviving Bank, as they exist at the Effective Time, shall pass to and vest in the Surviving Bank without any conveyance or other transfer; the Surviving Bank shall be considered the same business and corporate entity as each constituent bank with all the rights, powers and duties of each constituent bank; and the Surviving Bank shall be responsible for all the liabilities of every kind and description of each of the Company and the Surviving Bank existing as of the Effective Time, all in accordance with the provisions of applicable Law.

1.2 Time and Place of Closing. Unless otherwise mutually agreed to by SBC and the Company, the closing of the Merger (the “Closing”) shall take place in the offices of Alston & Bird LLP, 1201 West Peachtree Street, Atlanta, Georgia 30309 at 5:00 p.m., Eastern Time, on the date when the Effective Time is to occur (the “Closing Date”).

1.3 Effective Time. Subject to the terms and conditions hereof, the Parties shall use their reasonable best efforts to cause the Merger to take effect (the “Effective Time”) to occur on a mutually agreeable date following the date on which satisfaction or waiver of the conditions set forth in Article 5 has occurred (other

A-1

TABLE OF CONTENTS

than those conditions that by their nature are to be satisfied at the Closing, but subject to the fulfillment or waiver of those conditions).

1.4 Conversion of Company Common Stock.

(a) At the Effective Time, in each case subject to Section 1.4(d) and excluding Excluded Shares and subject to certain adjustments set forth in this Agreement, by virtue of the Merger and without any action on the part of the Parties or the holder thereof, each share of Company Common Stock that is issued and outstanding immediately prior to the Effective Time shall be converted into the right to receive, subject to the terms herein, the number of shares of SBC Common Stock that is equal to the Exchange Ratio (the “Merger Consideration”); provided, however, that in the event the conditions set forth in Section 5.2(j) of this Agreement are not satisfied, Seacoast shall have the option to adjust the Merger Consideration downward by an amount that equals the difference between the Company’s Consolidated Tangible Shareholders’ Equity and the Target Consolidated Tangible Shareholders’ Equity and waive the satisfaction of such condition set forth in Section 5.2(j) herein. The calculation methodology is set forth on Section 1.4(a) of the Seacoast Disclosure Letter. At least ten (10) days prior to the Closing Date, the Company and Seacoast shall agree on a schedule setting forth the expected Company Consolidated Tangible Shareholders’ Equity amount as of the Closing Date. The consideration which all of the Company shareholders are entitled to receive pursuant to this Article 1 is collectively referred to herein as the “Aggregate Merger Consideration.”

(b) At the Effective Time, all shares of Company Common Stock shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist as of the Effective Time, and each certificate or electronic book-entry previously representing any such shares of Company Common Stock (the “Company Certificates”) shall thereafter represent only the right to receive the Merger Consideration and any cash in lieu of fractional shares pursuant to Section 1.4(c), and any Dissenting Shares shall thereafter represent only the right to receive applicable payments as set forth in Section 2.3.

(c) Notwithstanding any other provision of this Agreement, each holder of shares of Company Common Stock exchanged pursuant to the Merger who would otherwise have been entitled to receive a fraction of a share of SBC Common Stock (after taking into account all Company Certificates delivered by such holder) shall receive, in lieu thereof, cash (without interest) in an amount equal to such fractional part of a share of SBC Common Stock multiplied by the Seacoast Closing Price less any applicable withholding taxes. No such holder will be entitled to dividends, voting rights, or any other rights as a shareholder in respect of any fractional shares.

(d) If, prior to the Effective Time, the issued and outstanding shares of SBC Common Stock or Company Common Stock shall have been increased, decreased, changed into or exchanged for a different number or kind of shares or securities as a result of a reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split, or other similar change in capitalization, then an appropriate and proportionate adjustment shall be made to the Merger Consideration.

(e) Each share of Company Common Stock issued and outstanding immediately prior to the Effective Time and owned by any of the Parties or their respective Subsidiaries (in each case other than shares of Company Common Stock held on behalf of third parties) shall, by virtue of the Merger and without any action on the part of the holder thereof, cease to be outstanding, shall be cancelled and retired without payment of any consideration therefor and shall cease to exist (together with the Dissenting Shares, the “Excluded Shares”).

1.5 SBC Common Stock. At and after the Effective Time, each share of SBC Common Stock issued and outstanding immediately prior to the Effective Time shall remain an issued and outstanding share of SBC Common Stock and shall not be affected by the Merger.

1.6 Company Equity Awards. At the Effective Time, each Company Option shall, by virtue of the Merger, automatically cease to be outstanding, and, in consideration therefor, SBC shall grant to each holder of Company Options, as of the Effective Time, an option to purchase shares of SBC Common Stock pursuant to the SBC Incentive Plan (each, a “Substitute SBC Option”), on the same terms and conditions (including applicable vesting percentages, exercise periods, payment methods, and expiration provisions (as such terms may be modified prior to Closing in accordance with this Agreement), but excluding general administrative

A-2

TABLE OF CONTENTS

terms and conditions which shall be governed in accordance with the SBC Incentive Plan) as applicable to each such Company Option as in effect immediately prior to the Effective Time, except that (A) the number of shares of SBC Common Stock subject to such Substitute SBC Option shall equal the product of (x) the number of shares of Company Common Stock subject to such Company Option immediately prior to the Effective Time, multiplied by (y) the Exchange Ratio, rounded down to the nearest whole share, and (B) the per share exercise price for the shares of SBC Common Stock issuable upon exercise of such Substitute SBC Option shall equal the quotient determined by dividing (x) the exercise price per share of Company Common Stock at which such Company Option was exercisable immediately prior to the Effective Time by (y) the Exchange Ratio, rounded up to the nearest whole cent; provided, however, that the exercise price and the number of shares of SBC Common Stock issuable upon exercise of such Substitute SBC Option shall be determined in a manner consistent with the requirements for a substitution of stock rights in accordance with Section 409A of the Code.

DELIVERY OF MERGER CONSIDERATION

2.1 Exchange Procedures.

(a) Delivery of Transmittal Materials. Prior to the Effective Time, SBC shall appoint an exchange agent (the “Exchange Agent”) to act as exchange agent hereunder. At or immediately prior to the Effective Time, SBC shall deposit, or cause to be deposited, with the Exchange Agent (i) SBC Common Stock issuable pursuant to Section 1.4(a) in book-entry form equal to the Aggregate Merger Consideration (excluding any fractional share consideration), and (ii) cash in immediately available funds in an amount sufficient to pay fractional share consideration and any dividends under Section 2.1(d). As promptly as practicable after the Effective Time (and within five Business Days), the Exchange Agent shall send to each former holder of record of shares of Company Common Stock, including holders of the Company Equity Awards who received Company Common Stock in accordance with the exercise of such Company Equity Awards prior to the Effective Time, but excluding the holders, if any, of Dissenting Shares, immediately prior to the Effective Time transmittal materials for use in exchanging such holder’s Company Certificates for the Merger Consideration (which shall specify that delivery shall be effected, and risk of loss and title to the Company Certificates shall pass, only upon proper delivery of such Company Certificates (or effective affidavit of loss in lieu thereof as provided in Section 2.1(e)) to the Exchange Agent).

(b) Delivery of Merger Consideration. After the Effective Time, following the surrender of a Company Certificate to the Exchange Agent (or effective affidavit of loss in lieu thereof as provided in Section 2.1(e)) in accordance with the terms of the letter of transmittal, duly executed, the holder of such Company Certificate shall be entitled to receive in exchange therefor the Merger Consideration in respect of the shares of Company Common Stock represented by its Company Certificate or Certificates. If any portion of the Merger Consideration is to be paid to a Person other than the Person in whose name a Company Certificate so surrendered is registered, it shall be a condition to such payment that such Company Certificate shall be properly endorsed or otherwise be in proper form for transfer, and the Person requesting such payment shall pay to the Exchange Agent any transfer or other similar Taxes required as a result of such payment to a Person other than the registered holder of such Company Certificate, or establish to the reasonable satisfaction of the Exchange Agent that such Tax has been paid or is not payable. Payments to holders of Dissenting Shares shall be made as required by the FFIC.

(c) Payment of Taxes. The Exchange Agent (or, after the agreement with the Exchange Agent is terminated, SBC) shall be entitled to deduct and withhold from the Merger Consideration (including cash in lieu of fractional shares of SBC Common Stock) otherwise payable pursuant to this Agreement to any holder of Company Common Stock such amounts as the Exchange Agent or SBC, as the case may be, is required to deduct and withhold under the Internal Revenue Code, or any provision of state, local, or foreign Tax law, with respect to the making of such payment. To the extent the amounts are so withheld by the Exchange Agent or SBC, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of shares of Company Common Stock in respect of whom such deduction and withholding was made by the Exchange Agent or SBC, as the case may be.

(d) Return of Merger Consideration to SBC. At any time upon request by SBC, SBC shall be entitled to require the Exchange Agent to deliver to it any remaining portion of the Merger Consideration not distributed within six months following the Effective Time to holders of Company Certificates that was deposited with the Exchange Agent (the “Exchange Fund”) (including any interest received with respect thereto and other income resulting from investments by the Exchange Agent, as directed by SBC), and holders shall be entitled to look only to SBC (subject to abandoned property, escheat or other similar laws) with respect to the Merger Consideration, any cash in lieu of fractional shares of SBC Common Stock and any dividends or other distributions with respect to SBC Common Stock payable upon due surrender of their Company Certificates, without any interest thereon. Notwithstanding the foregoing, neither SBC nor the Exchange Agent shall be liable to any holder of a Company Certificate for Merger Consideration (or dividends or distributions with respect thereto) or cash from the Exchange Fund in each case delivered to a public official pursuant to any applicable abandoned property, escheat or similar law.

(e) Lost Company Certificates. In the event any Company Certificates shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Company Certificate(s) to be lost, stolen or destroyed and, if required by SBC or the Exchange Agent, the posting by such Person of a bond in such sum as SBC may reasonably direct as indemnity against any claim that may be made against the Company or SBC with respect to such Company Certificate(s), the Exchange Agent will issue the Merger Consideration deliverable in respect of the shares of Company Common Stock represented by such lost, stolen or destroyed Company Certificates.

2.2 Rights of Former Company Shareholders. On or before the Closing Date, the stock transfer books of the Company shall be closed as to holders of Company Common Stock and no transfer of Company Common Stock by any such holder shall thereafter be made or recognized. Until surrendered for exchange in accordance with the provisions of Section 2.1, each Company Certificate (other than the Company Certificates representing Excluded Shares) shall from and after the Effective Time represent for all purposes only the right to receive the Merger Consideration in exchange therefor and any cash in lieu of fractional shares of SBC Common Stock to be issued or paid in consideration therefor upon surrender of such Company Certificate in accordance with Section 1.4(c), and any dividends or distributions to which such holder is entitled pursuant to this Article 2. No dividends or other distributions with respect to SBC Common Stock with a record date after the Effective Time shall be paid to the holder of any un-surrendered Company Certificate with respect to the shares of SBC Common Stock represented thereby, and no cash payment in lieu of fractional shares shall be paid to any such holder pursuant to Section 1.4(c), and all such dividends, other distributions and cash in lieu of fractional shares of SBC Common Stock shall be paid by SBC to the Exchange Agent and shall be included in the Exchange Fund, in each case until the surrender of such Company Certificate in accordance with this Article 2. Subject to the effect of applicable abandoned property, escheat or similar laws, following surrender of any such Company Certificate there shall promptly be delivered to such holder (i) whole shares of SBC Common Stock, in book-entry form, in an amount equal to the Merger Consideration to which such holder is entitled pursuant to Section 1.4(a), (ii) at the time of such surrender, the amount of dividends or other distributions, if applicable, with a record date after the Effective Time theretofore paid with respect to such whole shares of SBC Common Stock, (iii) the amount of any cash payable in lieu of a fractional share of SBC Common Stock to which such holder is entitled pursuant to Section 1.4(c), and (iv) at the appropriate payment date, the amount of dividends or other distributions, if applicable, with a record date after the Effective Time but prior to such surrender and with a payment date subsequent to such surrender payable with respect to such whole shares of SBC Common Stock. SBC shall make available to the Exchange Agent cash for these purposes, if necessary.

2.3 Dissenters’ Rights. Any Person who otherwise would be deemed a holder of Dissenting Shares (a “Dissenting Shareholder”) shall not be entitled to receive the applicable Merger Consideration (or cash in lieu of fractional shares) with respect to the Dissenting Shares unless and until such Person shall have failed to perfect or shall have effectively withdrawn or lost such holder’s right to dissent from the Merger under the Florida Financial Institutions Code (“FFIC”). Each Dissenting Shareholder shall be entitled to receive only the payment provided by the provisions of Section 658.44 of the FFIC with respect to shares of Company Common Stock owned by such Dissenting Shareholder. The Company shall give SBC (i) prompt notice of any written demands for appraisal, attempted withdrawals of such demands, and any other instruments served pursuant to applicable Law received by the Company relating to shareholders’ rights of appraisal and (ii) the opportunity to direct all negotiations and proceedings with respect to demand for appraisal under the FFIC. The Company shall not, except with the prior written consent of SBC, voluntarily make any payment with respect to any demands for appraisals of Dissenting Shares, offer to settle or settle any such demands or approve any withdrawal of any such demands.

(iii) Neither the execution and delivery of this Agreement by SBC or SNB, nor the consummation by either of them of the transactions contemplated hereby, nor compliance by them with any of the provisions hereof, will (A) violate conflict with or result in a breach of any provision of their respective Organizational Documents, or (B) constitute or result in a Default under, or require any Consent pursuant to, or result in the creation of any Lien on any material asset under, any Contract or Permit, or (C) subject to receipt of the Required Consents and the expiration of any waiting period required by Law, violate any Law or Order applicable to SBC or SNB or any of their respective material assets.

TABLE OF CONTENTS

Acquisition Proposal), and will keep Seacoast apprised of any related developments, discussions and negotiations on a current basis. The Company agrees that any breach by its Representatives of this Section 4.12 shall be deemed a breach by the Company.

(b) Notwithstanding the foregoing, if the Company’s Board of Directors concludes in good faith (and based upon the written advice of its outside counsel and after consultation with its financial advisor and outside legal counsel) that an Acquisition Proposal constitutes or would reasonably be expected to constitute a Superior Proposal and that failure to accept such Superior Proposal would reasonably be expected to result in a breach of its fiduciary obligations under applicable Laws, the Company Board of Directors may at any time prior to the Company Shareholder Approval (i) withdraw or modify (a “Change in Recommendation”) the Company Directors’ Recommendation or make or cause to be made any third party or public communication proposing or announcing an intention to withdraw or modify the Company Directors’ Recommendation, and (ii) terminate this Agreement to enter into a definitive agreement with respect to such Superior Proposal; provided, however, that the Board of Directors of the Company may not make a Change in Recommendation, and terminate this Agreement, with respect to an Acquisition Proposal unless (i) the Company shall not have breached this Section 4.12 in any respect and (ii) (A) the Board of Directors of the Company determines in good faith (after consultation with outside legal counsel and its financial advisors) that such Superior Proposal has been made and has not been withdrawn and continues or is reasonably expected to continue to be a Superior Proposal after taking into account all adjustments to the terms of this Agreement that may be offered by SBC under this Section 4.12(b); (B) the Company has given SBC at least four (4) Business Days’ prior written notice of its intention to take such actions set forth above (which notice shall specify the material terms and conditions of any such Superior Proposal (including the identity of the Person making such Superior Proposal)) and has contemporaneously provided an unredacted copy of the relevant proposed transaction agreements with the Person making such Superior Proposal; and (C) before effecting such Change in Recommendation, the Company has negotiated, and has caused its representatives to negotiate in good faith with SBC during such notice period to the extent SBC wishes to negotiate, to enable SBC to revise the terms of this Agreement such that it would cause such Superior Proposal to no longer constitute a Superior Proposal.

(e) If, within six (6) months after the Effective Time, any Covered Employee (other than those Covered Employees who receive change in control benefits or retention benefits pursuant to employment or retention agreements with the Company), is terminated by SBC or its Subsidiaries other than “for cause” or as a result of death, disability, or unsatisfactory job performance, then SBC shall pay severance to such Covered Employee in an amount as set forth in the severance policies set forth in Section 4.14(e)(i) of the Seacoast Disclosure Letter (and based upon the non-exempt and exempt status and/or title for the Covered Employee with the Company at the Closing).

(b) Seacoast agrees that all existing rights to indemnification and all existing limitations on Liability existing in favor of the directors, officers, and employees of the Company (the “Covered Parties”) as provided in their respective Organizational Documents as in effect as of the date of this Agreement shall survive the Merger and shall continue in full force and effect, and shall be honored by such entities or their respective successors as if they were the indemnifying party thereunder, without any amendment thereto; provided, that nothing contained in this Section 4.15(b) shall be deemed to preclude the liquidation, consolidation, or merger of SBC or SNB, in which case all of such rights to indemnification and limitations on Liability shall be deemed to so survive and continue notwithstanding any such liquidation, consolidation or merger. Without limiting the foregoing, in any case in which approval by Seacoast is required to effectuate any indemnification for any director or officer of the Company, Seacoast shall direct, at the election of the Indemnified Party that the determination of any such approval shall be made by independent counsel mutually agreed upon between Seacoast and the Indemnified Party.

(c) Seacoast, from and after the Effective Time, will directly or indirectly cause the Persons who served as directors or officers of the Company at or before the Effective Time to be covered by the Company’s existing directors’ and officers’ liability insurance policy; provided, that Seacoast may substitute therefor policies of at least the same coverage and amounts containing terms and conditions that are not less advantageous than such policy; provided further, that in no event shall the aggregate premiums applicable to coverage exceed 150% of the current annual premium paid by the Company (as set forth in Section 4.15(c) of the Company Disclosure Letter) for such insurance.

4.22 Approval of 280G Payments. If, after reviewing the 280G calculations and other supporting materials prepared by the Company and its Representatives, either the Company or Seacoast determines that any Person who is a “disqualified individual” has a right to any payments and/or benefits as a result of or in connection with the execution of this Agreement and the consummation of the transactions contemplated hereby that would be deemed to constitute “parachute payments” (as such terms are defined in Section 280G of the Internal Revenue Code and the regulations promulgated thereunder) absent approval by the shareholders of the Company, then the Company will undertake its best efforts to modify its obligations to provide such payments or benefits to the extent necessary such that, after giving effect to such modifications, the modified payments or benefits would not constitute a parachute payment to a disqualified individual based on the 280G calculations. If, in the opinion of Seacoast or its Representatives, the Company is not able to modify its obligations to make such payments or benefits comply with the foregoing within 30 days after determining that a payment or benefit would constitute a parachute payment to a disqualified individual, then at least three (3) Business Days prior to the Closing Date, the Company will take all necessary actions (including obtaining any required waivers or consents from each disqualified individual) to submit to a shareholder vote, in a manner that satisfies the shareholder approval requirements for exemption under Section 280G(b)(5)(A)(ii) of the Internal Revenue Code and the regulations promulgated thereunder, the right of each disqualified individual to receive or retain, as applicable, any payments and benefits to the extent necessary so that no payment or benefit received by such disqualified person shall be deemed a parachute payment. Such vote shall establish the disqualified individual’s right to the payment or benefits. The Company will be responsible for all liabilities and obligations related to the matters described in this Section 4.22, including any claims by disqualified individuals that they are entitled to payment or reimbursement for any related excise taxes. The Company will provide to Seacoast copies of any waivers, consents, and shareholder information statements or disclosures relating to Section 280G and the shareholder vote described in this Section 4.22, a reasonable period of time before disseminating such materials to the disqualified individuals and the Company’s shareholders, and will work with Seacoast in good faith regarding the inclusion of any comments provided by Seacoast thereto. Prior to the Closing, the Company shall deliver to Seacoast evidence that a vote of the Company’s shareholders who are entitled to vote was solicited in accordance with the foregoing provisions of this Section 4.22 and that the requisite number of shareholder votes was or was not obtained with respect thereto.

In no event shall the Company be required to pay the Termination Fee on more than one occasion.

RECITALS

WHEREAS, the Shareholders desire that Buyer and Seller consummate the transactions (the “Transactions”) set forth in that certain Agreement and Plan of Merger, dated as of [•], 2021 (as the same may be amended or supplemented, the “Merger Agreement”), by and among Buyer, Seacoast National Bank, and Seller, that provides for, among other things, the merger of Seller with and into Seacoast National Bank (the “Merger”); and

WHEREAS, the Shareholders, Seller, and Buyer are executing this Agreement as an inducement and condition to Buyer entering into, executing, and performing the Merger Agreement and consummating the Transactions.

NOW, THEREFORE, in consideration of, and as a material inducement to, entering into and the execution and delivery by Buyer of the Merger Agreement and the mutual covenants, conditions, and agreements contained herein and therein, and other good and valuable consideration, the receipt and sufficiency of which are acknowledged, the parties, intending to be legally bound, hereby agree as follows:

Representations and Warranties. Each Shareholder represents and warrants to Buyer severally, but not jointly, as follows:

The Shareholder has voting power over the number of shares (“Shareholder’s Shares”) of the common stock of Seller, par value $1.00 per share of the single class designated Common Stock (collectively, “Seller Stock”), set forth below such Shareholder’s name on the signature page hereto. Except for the Shareholder’s Shares, the Shareholder does not have voting power over any shares of Seller Stock.

This Agreement has been duly authorized, executed, and delivered by, and constitutes a valid and binding agreement of, the Shareholder, enforceable in accordance with its terms.

Neither the execution and delivery of this Agreement nor the consummation by the Shareholder of the transactions contemplated hereby will result in a violation of, or a default under, or conflict with, any contract, trust, commitment, agreement, understanding, arrangement, or restriction of any kind to which the Shareholder is a party or bound or to which the Shareholder’s Shares are subject. Consummation by the Shareholder of the transactions contemplated hereby will not violate, or require any consent, approval, or notice under, any provision of any judgment, order, decree, statute, law, rule, or regulation applicable to the Shareholder or the Shareholder’s Shares.

The Shareholder’s Shares and the certificates representing the Shareholder’s Shares are now, and at all times during the term hereof will be, held by the Shareholder, or by a nominee or custodian for the benefit of such Shareholder, free and clear of all pledges, liens, security interests, claims, proxies, voting trusts, or agreements, understandings, or arrangements or any other encumbrances whatsoever (any such encumbrance, a “Lien”), except for (i) any such Liens arising hereunder, and (ii) Liens, if any, which have been previously disclosed in writing to Buyer and will be satisfied and released at Closing.

The Shareholder understands and acknowledges that Buyer entered into the Merger Agreement in reliance upon the Shareholder’s execution and delivery of this Agreement. The Shareholder acknowledges

A-51

TABLE OF CONTENTS

that the irrevocable proxy set forth in Section 4 of this Agreement is granted in consideration of the execution and delivery of the Merger Agreement by Buyer.

No broker, investment banker, financial adviser, or other Person is entitled to any broker’s, finder’s, financial adviser’s or other similar fee or commission in connection with the transactions contemplated hereby based upon arrangements made by or on behalf of the Shareholder.

The Shareholder represents that there are no outstanding or valid proxies or voting rights given to any Person in connection with Shareholder’s Shares.

Voting Agreements. The Shareholder agrees with, and covenants to, Buyer as follows:

At any meeting of shareholders of Seller called to vote upon the Merger Agreement, the Merger, and the Transactions, and at any adjournment or postponement thereof, or in any other circumstances upon which a vote, consent, or other approval with respect to the Merger Agreement, the Merger, and the Transactions is sought (collectively, the “Shareholders’ Meeting”), the Shareholder shall vote (or cause to be voted) all of the Shareholder’s Shares in favor of the approval of the terms of the Merger Agreement, the Merger, and each of the Transactions, and shall not grant any proxies to any third party, except where such proxies are expressly directed to vote in favor of the Merger Agreement, the Merger, and the Transactions. The Shareholder hereby waives all notice and publication of notice of any Shareholders’ Meeting to be called or held with respect to the Merger Agreement, the Merger, and the Transactions.

At any Shareholders’ Meeting or in any other circumstances upon which their vote, consent, or other approval is sought, the Shareholder shall vote (or cause to be voted) such Shareholder’s Shares against (i) any acquisition proposal, including, without limitation, any merger or exchange agreement or merger or exchange (other than the Merger Agreement, the Merger, and the Transactions), consolidation, combination, sale of substantial assets, reorganization, recapitalization, dissolution, liquidation, or winding up of or by Seller; (ii) any action or agreement that would result in a breach of any covenant, representation or warranty, or any other obligation or agreement of Seller contained in the Merger Agreement or of Shareholder contained in this Agreement; and (iii) any amendment of Seller’s articles of incorporation or bylaws or other proposal or transaction involving Seller or any of its Subsidiaries, which amendment or other proposal or transaction would in any manner delay, impede, frustrate, prevent, or nullify the Merger Agreement, or any of the Transactions, other than an amendment or other proposal or transaction required by a regulatory authority or other Governmental Authority (each of the foregoing in clauses (i), (ii) or (iii) above, a “Competing Transaction”).

Shareholder further agrees not to vote or execute any written consent to rescind or amend in any manner any prior vote or written consent, as a shareholder of Seller, to approve or adopt the Merger Agreement unless this Agreement shall have been terminated in accordance with its terms.

Covenants. The Shareholder agrees with, and covenants to, Buyer as follows:

Without the prior written consent of Buyer, the Shareholder shall not (i) “Transfer” (which term shall include, without limitation, for the purposes of this Agreement, any sale, gift, pledge, transfer, hypothecation, or other disposition), or consent to any Transfer of, any or all of the Shareholder’s Shares or any interest therein, (ii) enter into any contract, option, or other agreement, arrangement, or understanding with respect to any Transfer of any or all of Shareholder’s Shares or any interest therein, (iii) grant or solicit any proxy, power of attorney, or other authorization in or with respect to Shareholder’s Shares, except for this Agreement, (iv) deposit Shareholder’s Shares into a voting trust or enter into any voting agreement, arrangement, or understanding with respect to Shareholder’s Shares for any purpose (other than to satisfy its obligations under this Agreement), or (v) initiate a shareholders’ vote or action by consent of Seller’s shareholders with respect to a Competing Transaction; provided, however, that the foregoing shall not preclude a Transfer in connection with bona fide estate planning purposes to the Shareholder’s affiliates or immediate family members, provided that as a condition to such Transfer, such affiliate or immediate family member shall execute an agreement that is identical to this Agreement (except to reflect the change in the ownership of the Shareholder’s Shares) and, provided further, that the assigning Shareholder shall remain jointly and severally liable for any breaches by any of his or her affiliates or immediate family members of the terms hereof. The restriction on the Transfer of the

A-52

TABLE OF CONTENTS

Shareholder’s Shares set forth in this Section 3(a) shall terminate upon the first to occur of (x) the Effective Time of the Merger and the Transactions or (y) the date upon which the Merger Agreement is terminated in accordance with its terms.

The Shareholder hereby waives any rights of appraisal, or rights to dissent from the Merger or the Transactions that such Shareholder may have.

The Shareholder shall not, nor shall it permit any investment banker, attorney, or other adviser or representative of the Shareholder to, directly or indirectly, (i) solicit, initiate, knowingly induce, or encourage, or knowingly take an action to facilitate the making of the submission of any Competing Transaction, or (ii) except as provided in the Merger Agreement, participate in any discussions or negotiations regarding, or furnish to any person any information with respect to, or take any other action to facilitate any inquiries or the making of any proposal that constitutes, or may reasonably be expected to lead to, any Competing Transactions, other than the Merger or the Transactions contemplated by the Merger Agreement.

Irrevocable Proxy. Subject to the last sentence of this Section 4, by execution of this Agreement, Shareholder does hereby appoint Buyer with the full power of substitution and resubstitution, as Shareholder’s true and lawful attorney and irrevocable proxy, to the full extent of Shareholder’s rights with respect to Shareholder’s Shares, to vote each of such Shareholder Shares that Shareholder shall be entitled to so vote with respect to the matters set forth in Section 2 hereof at any Shareholders’ Meeting, and at any adjournment or postponement thereof, and in connection with any action of the shareholders of Seller taken by written consent. Shareholder intends this proxy to be irrevocable and coupled with an interest hereafter until the termination of this Agreement pursuant to the terms of Section 9 hereof and hereby revokes any proxy previously granted by Shareholder with respect to the Shareholder Shares. Notwithstanding anything contained herein to the contrary, this irrevocable proxy shall automatically terminate upon the termination of this Agreement.

Certain Events. The Shareholder agrees that this Agreement and the obligations hereunder shall attach to the Shareholder’s Shares and shall be binding upon any person or entity to which legal or beneficial ownership of Shareholder’s Shares shall pass, whether by operation of law or otherwise, including the Shareholder’s successors or assigns. In the event of any stock split, stock dividend, merger, exchange, reorganization, recapitalization, or other change in the capital structure of the Seller affecting the Seller Common Stock, or the acquisition of additional shares of Seller Stock or other voting securities of Seller by Shareholder, the number of shares of Seller Stock subject to the terms of this Agreement shall be adjusted appropriately and this Agreement and the obligations hereunder shall attach to any additional shares of Seller Stock or other voting securities of the Seller issued to or acquired by the Shareholder.

Specific Performance; Remedies; Attorneys’ Fees. Shareholder acknowledges that it is a condition to the willingness of Buyer to enter into the Merger Agreement that Shareholder execute and deliver this Agreement and that it will be impossible to measure in money the damage to Buyer if Shareholder fails to comply with the obligations imposed by this Agreement and that, in the event of any such failure, irreparable damage will occur and Buyer will not have any adequate remedy at law. It is accordingly agreed that Buyer shall be entitled to seek specific performance and injunctive or other equitable relief as a remedy for any such breach or to prevent any breach and to enforce specifically the terms and provisions of this Agreement, in addition to any other remedy to which they are entitled at law or in equity. Seller agrees that it shall not oppose the granting of such relief on the basis that Buyer has an adequate remedy at law. In addition, any third party participating with Shareholder or receiving from Shareholder assistance in violation of this Agreement and of the rights of Buyer hereunder, and any such participation by such third party with Shareholder in activities in violation of the Shareholder’s agreement with Buyer set forth in this Agreement, may give rise to claims by Buyer against such third party and Buyer acknowledges that Shareholder may be responsible for any associated liabilities caused by such third party. In any legal action or other proceeding relating to this Agreement and the transactions contemplated hereby or if the enforcement of any provision of this Agreement is brought against either Party, the prevailing Party in such action or proceeding shall be entitled to recover all reasonable expenses relating thereto (including reasonable attorneys’ fees and expenses, court costs, and expenses incident to arbitration, appellate, and post-judgment proceedings) from the other Party, in addition to any other relief to which such prevailing Party may be entitled.

TABLE OF CONTENTS

Further Assurances. The Shareholder shall, upon the request of the Buyer, promptly execute and deliver any additional documents and take such further actions as may reasonably be deemed by the Buyer to be necessary or desirable to carry out the provisions hereof and to vest in the Buyer the power to vote such Shareholder’s Shares as contemplated by Section 2 and 4 of this Agreement and the other irrevocable proxies provided herein.

Confidentiality. The undersigned recognizes and acknowledges that he or she may have access to certain confidential information of the Buyer and its subsidiaries (including that obtained from the Seller and its shareholders in connection with the Transactions), the Seller and its Subsidiaries and their shareholders, including, without limitation, customer lists, information regarding customers, confidential methods of operation, lending, credit information, organization, pricing, mark-ups, commissions, and other information and that all such information constitutes valuable, special, and unique property of the Buyer, the Seller, and the Buyer’s shareholders. All such information, which shall exclude any information that is publicly known or hereafter becomes publicly known other than as a result of any action or omission by the undersigned, is herein referred to as “Confidential Information.” The undersigned will not disclose or directly or indirectly utilize in any manner any such Confidential Information for Shareholder’s own benefit or the benefit of anyone other than the Buyer and/or its shareholders during the term of this Agreement and for a period of two (2) years after the termination of this Agreement pursuant to Section 9; provided that the undersigned may disclose such Confidential Information as required by law, court order, or other valid and appropriate legal process.

Term of Agreement; Termination. The term of this Agreement shall commence on the date hereof. This Agreement may be terminated at any time prior to consummation of the transactions contemplated by the Merger Agreement by the written consent of the parties hereto, and this Agreement shall be automatically terminated upon either (i) the termination of the Merger Agreement in accordance with its terms, or (ii) the consummation of the Merger. Upon such termination, no party shall have any further obligations or liabilities hereunder; provided, however, that such termination shall not relieve any party from liability for any breach of this Agreement prior to such termination; provided further that the provisions of Section 8 of this Agreement shall remain in full force and effect regardless of any such termination pursuant to this Section 9.

Severability. In the event that any one or more provisions of this Agreement shall for any reason be held invalid, illegal, or unenforceable in any respect by any court of competent jurisdiction, such invalidity, illegality, or unenforceability shall not affect any other provisions of this Agreement, and the parties shall use their reasonable best efforts to substitute a valid, legal, and enforceable provision which, insofar as practical, implements the purpose and intents of this Agreement.

From the Effective Time and thereafter for so long as such information remains Confidential Information, Director shall not directly or indirectly transmit or disclose any Confidential Information to any Person, or use or permit others to use any such Confidential Information, directly or indirectly, for any purpose, without the prior express written consent of the Chief Executive Officer of Buyer, which consent may be withheld in the sole discretion of Buyer’s Chief Executive Officer.

For purposes of this Agreement, “Compete” means to engage or participate, other than as a consumer or user, directly or indirectly, or products or services, in Business Activities (or to prepare to engage or participate in Business Activities) on Director’s own behalf, or with, for or on behalf of (i) any other financial institution as an officer, director, manager, owner, partner, joint venture, consultant, independent contractor, employee, or shareholder of, or (ii) any other Person, business, or enterprise. For purposes of this Agreement, “Business Activities” shall be any business activities conducted by Buyer, Seller, SNB, or any of their Affiliated Companies, which consist of commercial or consumer loans and extensions of credit, letters of credit, commercial and consumer deposits and deposit accounts, securities repurchase agreements and sweep accounts, cash management services, money transfer and bill payment services, internet or electronic banking, automated teller machines, IRA and retirement accounts, commercial or consumer mortgage loans, and commercial or consumer home equity lines of credit.

Nothing in this Agreement shall prohibit a Director or any of such Director’s Affiliated Companies from continuing to hold outstanding securities of an entity that engages in Business Activities; provided that such securities were held by the Director or any of such Director’s Affiliated Company as of the date of this Agreement.

(e) Enforceability of Covenants. Director acknowledges and agrees that the covenants in this Agreement are direct consideration for a sale of a business and should be governed by standards applicable to restrictive covenants entered into in connection with a sale of a business. Director acknowledges that each of Buyer, SNB, and its Affiliated Companies have a current and future expectation of business within the Restricted Area and from the current and proposed customers of Seller that are derived from the acquisition of Seller by Buyer. Director acknowledges that the term, geographic area, and scope of the covenants set forth in this Agreement are reasonable, and agrees that he or she will not, in any action, suit or other proceeding, deny the reasonableness of, or assert the unreasonableness of, the premises, consideration, or scope of the covenants set forth herein. Director agrees that his or her position as a director of Seller involves duties and authority relating to all aspects of the Business Activities and all of the Restricted Area. Director further acknowledges that complying with the provisions contained in this Agreement will not preclude him or her from engaging in a lawful profession, trade, or business, or from becoming gainfully employed. Director and Buyer agree that Director’s obligations under the above covenants are separate and distinct under this Agreement, and the failure or alleged failure of the Buyer to perform its obligations under any other provisions of this Agreement shall not constitute a defense to the enforceability of this covenant. Director and Buyer agree that if any portion of the foregoing provisions is deemed to be unenforceable because the geography, time, or scope of activities restricted is deemed to be too broad, the court shall be authorized to substitute for the overbroad term an enforceable term that will enable the enforcement of the covenants to the

A-63

TABLE OF CONTENTS

maximum extent possible under applicable law. Director acknowledges and agrees that any breach or threatened breach of this covenant will result in irreparable damage and injury to the Buyer, SNB, and their Affiliated Companies and that damages arising out of such breach would be difficult to ascertain. Director hereby agrees that, in addition to all other remedies provided at law or in equity, Buyer will be entitled to exercise all rights including, without limitation, obtaining one or more temporary restraining orders, injunctive relief, and other equitable relief, including specific performance in the event of any breach or threatened breach of this Agreement, without the necessity of posting any bond or security (all of which are waived by the Director), and to exercise all other rights or remedies, at law or in equity, including, without limitation, the rights to damages.

No waiver by either party hereto at any time of any breach by the other party hereto of, or compliance with, any condition or provision of this Agreement to be performed by such other party shall be deemed a waiver of dissimilar provisions or conditions at the same or any prior subsequent time.

(a) Severability. If any provision or covenant, or any part thereof, of this Agreement should be held by any court to be invalid, illegal, or unenforceable, either in whole or in part, such invalidity, illegality, or unenforceability shall not affect the validity, legality, or enforceability of the remaining provisions or covenants, or any part thereof, of this Agreement, all of which shall remain in full force and effect.

(b) Attorneys’ Fees. In any legal action or other proceeding relating to this Agreement and the transactions contemplated hereby or if the enforcement of any right or benefit provided by this Agreement is brought against a Party, the prevailing Party in any such legal action or other proceeding pursuant to which an arbitral panel, court, or other Governmental Authority issues a final order, judgment, decree, or award granting substantially the relief sought shall be entitled, upon demand, to be paid by the other Party, all reasonable costs incurred in connection with such legal action or other proceeding, including the reasonable legal fees and charges of counsel, court costs, and expenses incident to arbitration, appellate and post-judgment proceedings, provided no party shall be entitled to any punitive or exemplary damages, which are hereby waived.

With respect to any such court action, Director hereby (i) irrevocably submits to personal jurisdiction of such courts; (ii) consents to service of process; (iii) consents to venue; and (iv) waives any other requirement (whether imposed by statute, rule of court, or otherwise) with respect to personal jurisdiction, service of process, or venue. Both parties hereto further agree that the court identified in this Agreement is a convenient forum for any dispute that may arise herefrom and that neither party shall raise as a defense that such courts are not convenient forums.

For purposes of this Agreement, “Compete” means to engage or participate , other than as a consumer or user, directly or indirectly, of products and services, in Business Activities (or to prepare to engage or participate in Business Activities) on Employee’s own behalf, or with, for, or on behalf of (i) any other financial institution as an officer, director, manager, owner, partner, joint venture, consultant, independent contractor, employee, or shareholder of, or (ii) any other Person, business, or enterprise.

Employee and Buyer agree that if any portion of the foregoing provisions is deemed to be unenforceable because the geography, time or scope of activities restricted is deemed to be too broad, the court shall be authorized to substitute for the overbroad term an enforceable term that will enable the enforcement of the covenants to the maximum extent possible under applicable law. Employee acknowledges and agrees that any breach or threatened breach of this covenant will result in irreparable damage and injury to the Buyer, SNB and their Affiliated Companies and that damages arising out of such breach would be difficult to ascertain.

Board of Directors
Legacy Bank of Florida
1300 Glades Road, Suite 120-140W
1200 the Company North
Boca Raton, Florida 33431

Dear Board of Directors:

Hovde Group, LLC (“we” or “Hovde”) understands that Seacoast Banking Corporation of Florida, a Florida corporation (“SBC”), Seacoast National Bank, a national banking association and wholly-owned subsidiary of SBC (“SNB” and collectively with SBC, “Seacoast”), and Legacy Bank of Florida, a Florida state-chartered bank (the “Company”) are about to enter into an Agreement and Plan of Merger (the “Agreement”) to be effective on or about March 22, 2021. As used herein, the term “Parties” shall mean Seacoast and the Company. Capitalized terms used herein that are not otherwise defined shall have the same meanings attributed to them in the Agreement, and all Section references shall refer to Sections in the Agreement. For purposes of our analysis and opinion, Agreement as used herein shall refer to the draft Agreement dated March 18, 2021 provided to Hovde by the Company.

As set forth in the Agreement, at the Effective Time, the Company shall be merged with and into SNB in accordance with the provisions of 12 U.S.C. Section 215 and with the effect provided in 12 U.S.C. Section 215 (the “Merger”). SNB shall be the surviving bank (the “Surviving Bank”) resulting from the Merger and the separate existence of the Company shall thereupon cease. SNB shall continue to be governed by the Laws of the United States, and the separate existence of SNB with all of its rights, privileges, immunities, powers and franchises shall continue unaffected by the Merger. The Surviving Bank shall be considered the same business and corporate entity as each constituent bank with all the rights, powers and duties of each constituent bank. It is the intention of the Parties to the Agreement that the Merger, for federal income tax purposes, shall qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code and that the Agreement shall constitute a “plan of reorganization” for purposes of Sections 354 and 361 of the Internal Revenue Code. The business purpose of the Merger is to combine two financial institutions to create a strong commercial banking franchise.

The Agreement provides that at the Effective Time, in each case subject to Section 1.4(d) and excluding Excluded Shares and subject to certain adjustments set forth in the Agreement, by virtue of the Merger and without any action on the part of the Parties or the holder thereof, each share of Company Common Stock that is issued and outstanding immediately prior to the Effective Time shall be converted into the right to receive, subject to the terms of the Agreement, the number of shares of SBC Common Stock that is equal to the Exchange Ratio (the “Merger Consideration”); provided, however, that in the event the conditions set forth in Section 5.2(j) of the Agreement are not satisfied, Seacoast shall have the option to adjust the Merger Consideration downward by an amount that equals the difference between the Company’s Consolidated Tangible Shareholders’ Equity and the Target Consolidated Tangible Shareholders’ Equity and waive the satisfaction of such condition set forth in Section 5.2(j). At least ten (10) days prior to the Closing Date, the Company and Seacoast shall agree on a schedule setting forth the expected Company Consolidated Tangible Shareholders’ Equity amount as of the Closing Date. The consideration which all of the Company shareholders are entitled to receive pursuant to the above provisions is collectively referred to as the “Aggregate Merger Consideration”.

B-1

TABLE OF CONTENTS

The obligations of Seacoast to fulfill the terms of the Agreement and consummate the Merger and the other transactions contemplated therein are subject to the satisfaction of the conditions set forth in Section 5.2 of the Agreement. Section 5.2(j) of the Agreement stipulates the requirement that the Company’s Consolidated Tangible Shareholders’ Equity (as defined in Section 7.1 of the Agreement) as of the close of business on the fifth Business Day prior to the Closing Date shall be an amount not less than the Target Consolidated Tangible Shareholders’ Equity, and the Company’s general allowance for loan and lease losses shall be an amount not less than 0.75% of total loans and leases outstanding excluding those made pursuant to the Paycheck Protection Program. The Target Consolidated Shareholders’ Equity is defined as being $58.2 million. SBC shall have the option to adjust the Merger Consideration downward by an amount that equals the difference between the Company’s Consolidated Tangible Shareholders’ Equity and the Target Consolidated Tangible Shareholders’ Equity and waive the satisfaction of such condition set forth in Section 5.2(j).

At the Effective Time, each Company Option shall, by virtue of the Merger, automatically cease to be outstanding, and, in consideration therefor, SBC shall grant to each holder of Company Options, as of the Effective Time, an option to purchase shares of SBC Common Stock pursuant to the SBC Incentive Plan (each, a “Substitute SBC Option”), on the same terms and conditions as applicable to each such Company Option as in effect immediately prior to the Effective Time, except that (A) the number of shares of SBC Common Stock subject to such Substitute SBC Option shall equal the product of (x) the number of shares of Company Common Stock subject to such Company Option immediately prior to the Effective Time, multiplied by (y) the Exchange Ratio, rounded down to the nearest whole share, and (B) the per share exercise price for the shares of SBC Common Stock issuable upon exercise of such Substitute SBC Option shall equal the quotient determined by dividing (x) the exercise price per share of Company Common Stock at which such Company Option was exercisable immediately prior to the Effective Time by (y) the Exchange Ratio, rounded up to the nearest whole cent. No Company Equity Award shall be outstanding as of the Effective Time, and no obligations to issue Company Equity Awards shall exist following the Effective Time. Prior to the Effective Time, the Company shall take all actions necessary to effect the treatment of the Company Options as provided in Section 1.6 of the Agreement, to terminate the Company Stock Plans as of the Effective Time, and to cause the provisions in any other Company Benefit Plan providing for the issuance, transfer or grant of any capital stock of the Company or any interest in respect of any capital stock of the Company to terminate and be of no further force and effect as of the Effective Time.

We note that the Agreement may be terminated at any time prior to the Effective Time as set forth in Section 6.1 of the Agreement including among other termination provisions (a) by mutual consent of SBC and the Company; (b) by either Party in the event that (i) any Regulatory Consent required to be obtained from any Governmental Authority has been denied or (ii) the Company Shareholder Approval has not been obtained by reason of the failure to obtain the required vote at the Company shareholders’ meeting where the Agreement was presented to such shareholders for approval and voted upon; (c) by either Party in the event that the Merger has not been consummated by October 31, 2021; (d) by SBC in the event that (i) the Company has withdrawn, qualified or modified the Company Directors’ Recommendation in a manner adverse to SBC or shall have resolved to do any of the foregoing, (ii) the Company has failed to substantially comply with its obligations under Sections 4.5 or 4.12, or (iii) the Board of Directors of the Company has recommended, endorsed, accepted or agreed to an Acquisition Proposal; (e) by the Company in the event that (i) the Board of Directors of the Company has determined in accordance with Section 4.12 that a Superior Proposal has been made with respect to it and has not been withdrawn, and (ii) neither the Company nor any of its Representatives has failed to comply in all material respects with Section 4.12; and (f) by SBC if holders of more than five percent (5.0%) in the aggregate of the outstanding shares of Company Common Stock shall have voted such shares against the Agreement or the Merger at any meeting called for the purpose of voting thereon. In the event that the Agreement is terminated pursuant to certain conditions of Section 6.1, including termination if Company shall have received or there shall have been publicly announced an Acquisition Proposal that has not been formally withdrawn or abandoned prior to such termination, and within twelve (12) months following such termination an Acquisition Proposal is consummated or a definitive agreement or letter of intent is entered into by the Company with respect to an Acquisition Proposal, the Company shall pay SBC the Termination Fee of $4,600,000.

With your knowledge and consent and for purposes of our analysis and opinion we have assumed that (i) the closing price of SBC Common Stock on March 19, 2021 is $38.24 per share; (ii) the Exchange Ratio is 0.1703 and has not been adjusted as provided in the Agreement; (iii) there has been no downward adjustment

of the Merger Consideration due to the Company’s Consolidated Tangible Shareholders’ Equity being less than the Target Consolidated Tangible Shareholders’ Equity; and (iv) there are 15,772,897 shares of the Company Common Stock outstanding as of March 19, 2021, and thereby, the value of the Aggregate Merger Consideration is $103,335,204. Additionally, we have assumed that (i) there are Company options outstanding as of March 19, 2021 to purchase 2,128,754 shares of the Company Common Stock; (ii) the weighted average exercise price per share of the Company’s options as of March 19, 2021 is $2.85 per share of Company Common Stock; and (iii) there would be issued 362,527 Substitute SBC Options to purchase SBC Common Stock at $16.74 per SBC share, and thereby, the total Company Option Value is $7,877,136. The total Merger Value is equal to the sum of the value of the Aggregate Merger Consideration of $103,335,204 plus the value of the total Company Option Value of $7,877,136, and therefore for purposes of our analysis and opinion, we have assumed that the total Merger Value is $111,212,341.

You have requested our opinion as to whether the total Merger Value received by the shareholders and option holders of the Company in the Merger pursuant to the Agreement is fair, from a financial point of view, to the holders of the Company Common Stock. Our opinion addresses only the fairness of the total Merger Value, and we are not opining on any individual stock, cash, option, or other components of the consideration.

During the course of our engagement and for the purposes of the opinion set forth herein, we have:

(i)

reviewed a draft of the Agreement dated March 18, 2021 as provided to Hovde by the Company;

(ii)

reviewed unaudited financial statements for the Company for the twelve month period ended December 31, 2020;

(iii)

reviewed certain historical annual reports of the Company, including the Company’s audited annual report for the years ended December 31, 2019 and 2018;

(iv)

reviewed certain historical publicly available business and financial information concerning the Company;

(v)

reviewed certain internal financial statements and other financial and operating data concerning the Company;

(vi)

reviewed financial projections prepared by certain members of senior management of the Company;

(vii)

discussed with certain members of senior management of the Company the business, financial condition, results of operations and future prospects of the Company; the history and past and current operations of the Company; and the Company’s and the SBC’s assessment of the rationale for the Merger;

(viii)

reviewed and analyzed materials detailing the Merger prepared by SBC and the Company;

(ix)

assessed current general economic, market and financial conditions;

(x)

(xi)

taken into consideration our experience in other similar transactions and securities valuations as well as our knowledge of the banking and financial services industry;

(xii)

reviewed certain publicly available financial and stock market data relating to selected public companies that we deemed relevant to our analysis; and

(xiii)

performed such other analyses and considered such other factors as we have deemed appropriate.

We have assumed, without investigation, that there have been, and from the date hereof through the Effective Time will be, no material changes in the financial condition and results of operations of the Company or SBC since the date of the latest financial information described above. We have further assumed, without

B-3

TABLE OF CONTENTS

independent verification, that the representations and financial and other information included in the Agreement and all other related documents and instruments that are referred to therein or otherwise provided to us by the Company and SBC are true and complete. We have relied upon the management of the Company as to the reasonableness and achievability of the financial forecasts, projections and other forward-looking information provided to Hovde by the Company and SBC and the Company’s professionals, and we assumed such forecasts, projections and other forward-looking information have been reasonably prepared by the Company, SBC and the Company’s professionals on a basis reflecting the best currently available information and the Company’s, the SBC’s and the Company’s professionals judgments and estimates. We have assumed that such forecasts, projections and other forward-looking information would be realized in the amounts and at the times contemplated thereby, and we do not assume any responsibility for the accuracy or reasonableness thereof. We have been authorized by the Company to rely upon such forecasts, projections and other information and data, and we express no view as to any such forecasts, projections or other forward-looking information or data, or the bases or assumptions on which they were prepared.

In performing our review, we have assumed and relied upon the accuracy and completeness of all of the financial and other information that was available to us from public sources, that was provided to us by the Company or SBC or their respective representatives or that was otherwise reviewed by us for purposes of rendering this opinion. We have further relied on the assurances of the respective managements of the Company and SBC that they are not aware of any facts or circumstances that would make any of such information inaccurate or misleading. We have not been asked to undertake, and have not undertaken, an independent verification of any of such information, and we do not assume any responsibility or liability for the accuracy or completeness thereof. We have assumed that each Party to the Agreement would advise us promptly if any information previously provided to us became inaccurate or was required to be updated during the period of our review.

We are not experts in the evaluation of loan and lease portfolios for purposes of assessing the adequacy of the allowances for losses with respect thereto. We have assumed that such allowances for the Company and SBC are, in the aggregate, adequate to cover such losses and will be adequate on a pro forma basis for the combined entity. We were not requested to make, and have not made, an independent evaluation, physical inspection or appraisal of the assets, properties, facilities, or liabilities (contingent or otherwise) of the Company or SBC, the collateral securing any such assets or liabilities, or the collectability of any such assets, and we were not furnished with any such evaluations or appraisals; nor did we review any loan or credit files of the Company or SBC.

We have undertaken no independent analysis of any pending or threatened litigation, regulatory action, possible unasserted claims or other contingent liabilities to which the Company or SBC is a party or may be subject, and our opinion makes no assumption concerning, and therefore does not consider, the possible assertion of claims, outcomes or damages arising out of any such matters. We have also assumed, with your consent, that the Company and SBC are not parties to any material pending transaction, including without limitation any financing, recapitalization, acquisition or merger, divestiture or spin-off, other than the Merger contemplated by the Agreement.

We have relied upon and assumed, with your consent and without independent verification, that the Merger will be consummated substantially in accordance with the terms set forth in the Agreement, without any waiver of material terms or conditions by the Company, SBC or any other party to the Agreement and that the final Agreement will not differ materially from the draft we reviewed. We have assumed that the Merger will be consummated in compliance with all applicable laws and regulations. The Company has advised us that they are not aware of any factors that would impede any necessary regulatory or governmental approval of the Merger. We have assumed that the necessary regulatory and governmental approvals as granted will not be subject to any conditions that would be unduly burdensome on the Company or SBC or would have a material adverse effect on the contemplated benefits of the Merger.

Our opinion does not consider, include or address: (i) any legal, tax, accounting, or regulatory consequences of the Merger on the Company or its stockholders; (ii) any advice or opinions provided by any other advisor to the Board or the Company; (iii) any other strategic alternatives that might be available to the Company; or (iv) whether SBC has sufficient cash or other sources of funds to enable it to pay the consideration contemplated by the Merger.

TABLE OF CONTENTS

Our opinion does not constitute a recommendation to the Company as to whether or not the Company should enter into the Agreement or to any shareholders of the Company as to how such shareholders should vote at any meetings of shareholders called to consider and vote upon the Merger. Our opinion does not address the underlying business decision to proceed with the Merger or the fairness of the amount or nature of the compensation, if any, to be received by any of the officers, directors or employees of the Company relative to the amount of consideration to be paid with respect to the Merger. Our opinion should not be construed as implying that the total Merger Value is necessarily the highest or best price that could be obtained by the Company in a sale, merger, or combination transaction with a third party. Other than as specifically set forth herein, we are not expressing any opinion with respect to the terms and provisions of the Agreement or the enforceability of any such terms or provisions. Our opinion is not a solvency opinion and does not in any way address the solvency or financial condition of the Company or SBC.

This opinion was approved by Hovde’s fairness opinion committee. This letter is directed solely to the board of directors of the Company and is not to be used for any other purpose or quoted or referred to, in whole or in part, in any registration statement, prospectus, proxy statement, or any other document, except in each case in accordance with our prior written consent; provided, however, that we hereby consent to the inclusion and reference to this letter in any registration statement, proxy statement or information statement to be delivered to the holders of the Company’s Common Stock in connection with the Merger if, and only if, (i) this letter is quoted in full or attached as an exhibit to such document, (ii) this letter has not been withdrawn prior to the date of such document, and (iii) any description of or reference to Hovde or the analyses performed by Hovde or any summary of this opinion in such filing is in a form acceptable to Hovde and its counsel in the exercise of their reasonable judgment.

Our opinion is based solely upon the information available to us and described above, and the economic, market and other circumstances as they exist as of the date hereof. Events occurring and information that becomes available after the date hereof could materially affect the assumptions and analyses used in preparing this opinion. We have not undertaken to update, revise, reaffirm or withdraw this opinion or to otherwise comment upon events occurring or information that becomes available after the date hereof.

In arriving at this opinion, Hovde did not attribute any particular weight to any single analysis or factor considered by it, but rather made qualitative judgments as to the significance and relevance of each analysis and factor. Accordingly, Hovde believes that its analyses must be considered as a whole and that selecting portions of its analyses, without considering all analyses, would create an incomplete view of the process underlying this opinion.

Hovde, as part of its investment banking business, regularly performs valuations of businesses and their securities in connection with mergers and acquisitions and other corporate transactions. In addition to being retained to render this opinion letter, we were retained by the Company to act as its financial advisor in connection with the Merger. In connection with our services, we will receive from the Company a fairness opinion fee that is contingent upon the issuance of this opinion letter and a completion fee that is contingent upon the consummation of the Merger; the fairness opinion fee will be credited in full towards the portion of the completion fee which will become payable to Hovde upon the consummation of the Merger. The Company has also agreed to indemnify us and our affiliates for certain liabilities that may arise out of our engagement.

Other than in connection with this present engagement, in the past two years, Hovde has not provided investment banking or financial advisory services to the Company. During the past two years preceding the date of this opinion Hovde has not provided any investment banking or financial advisory services to SBC for which it received a fee. We or our affiliates may presently or in the future seek or receive compensation from SBC in connection with future transactions, or in connection with potential advisory services and corporate transactions, although to our knowledge none are expected at this time. In the ordinary course of our business as a broker/dealer, we may from time to time purchase securities from, and sell securities to, the Company or SBC or their affiliates. Except for the foregoing, during the past two years there have not been, and there currently are no mutual understandings contemplating in the future, any material relationships between Hovde and the Company or SBC.

607.1330 Court action

(1)

If a shareholder makes demand for payment under s. 607.1326 which remains unsettled, the corporation shall commence a proceeding within 60 days after receiving the payment demand and petition the court to determine the fair value of the shares and accrued interest from the date of the corporate action. If the corporation does not commence the proceeding within the 60-day period, any shareholder who has made a demand pursuant to s. 607.1326 may commence the proceeding in the name of the corporation.

(2)

The proceeding shall be commenced in the circuit court in the applicable county. If by virtue of the corporate action becoming effective the entity has become a foreign eligible entity without a registered office in this state, the proceeding shall be commenced in the county in this state in which the principal office or registered office of the domestic corporation merged with the foreign eligible entity was located immediately before the time the corporate action became effective. If such entity has, and immediately before the corporate action became effective had, no principal or registered office in this state, then the proceeding shall be commenced in the county in this state in which the corporation has, or immediately before the time the corporate action became effective had, an office in this state. If such entity has, or immediately before the time the corporate action became effective had, no office in this state, the proceeding shall be commenced in the county in which the corporation’s registered office is or was last located.

(3)

All shareholders, whether or not residents of this state, whose demands remain unsettled shall be made parties to the proceeding as in an action against their shares. The corporation shall serve a copy of the initial pleading in such proceeding upon each shareholder party who is a resident of this state in the manner provided by law for the service of a summons and complaint and upon each nonresident shareholder party by registered or certified mail or by publication as provided by law.

(4)

The jurisdiction of the court in which the proceeding is commenced under subsection (2) is plenary and exclusive. If it so elects, the court may appoint one or more persons as appraisers to receive evidence and recommend a decision on the question of fair value. The appraisers shall have the powers described in the order appointing them or in any amendment to the order. The shareholders demanding appraisal rights are entitled to the same discovery rights as parties in other civil proceedings. There shall be no right to a jury trial.

(5)

Each shareholder made a party to the proceeding is entitled to judgment for the amount of the fair value of such shareholder’s shares, plus accrued interest, as found by the court.

(6)

The corporation shall pay each such shareholder the amount found to be due within 10 days after final determination of the proceedings. Upon payment of the judgment, the shareholder shall cease to have any rights to receive any further consideration with respect to such shares other than any amounts ordered to be paid for court costs and attorney fees under s. 607.1331.

To the extent the corporation fails to make a required payment pursuant to s. 607.1324, the shareholder may sue directly for the amount owed and, to the extent successful, shall be entitled to recover from the corporation all costs and expenses of the suit, including attorney fees.

607.1332 Disposition of acquired shares

Shares acquired by a corporation pursuant to payment of the agreed value thereof or pursuant to payment of the judgment entered therefor, as provided in this chapter, may be held and disposed of by such corporation as authorized but unissued shares of the corporation, except that, in the case of a merger or share exchange, they may be held and disposed of as the plan of merger or share exchange otherwise provides. The shares of the survivor into which the shares of such shareholders demanding appraisal rights would have been converted had they assented to the merger shall have the status of authorized but unissued shares of the survivor.

607.1333 Limitation on corporate payment

(1)

No payment shall be made to a shareholder seeking appraisal rights if, at the time of payment, the corporation is unable to meet the distribution standards of s. 607.06401. In such event, the shareholder shall, at the shareholder’s option:

(a)

Withdraw his, her, or its notice of intent to assert appraisal rights, which shall in such event be deemed withdrawn with the consent of the corporation; or

(b)

Retain his, her, or its status as a claimant against the corporation and, if it is liquidated, be subordinated to the rights of creditors of the corporation, but have rights superior to the shareholders not asserting appraisal rights, and if the corporation is not liquidated, retain his, her, or its right to be paid for the shares, which right the corporation shall be obliged to satisfy when the restrictions of this section do not apply.

(2)

The shareholder shall exercise the option under paragraph (1)(a) or paragraph (1)(b) by written notice filed with the corporation within 30 days after the corporation has given written notice that the payment for shares cannot be made because of the restrictions of this section. If the shareholder fails to exercise the option, the shareholder shall be deemed to have withdrawn his or her notice of intent to assert appraisal rights.

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Directors and Officers of Seacoast

The Florida Business Corporation Act, as amended, or the “FBCA,” permits, under certain circumstances, the indemnification of officers, directors, employees and agents of a corporation with respect to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, to which such person was or is a party or is threatened to be made a party, by reason of his or her being an officer, director, employee or agent of the corporation, or is or was serving at the request of, such corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against liability incurred in connection with such proceeding, including appeals thereof; provided, however, that the officer, director, employee or agent acted in good faith and in a manner that he or she reasonably believed to be in, or not opposed to, the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. The termination of any such third-party action by judgment, order, settlement, or conviction or upon a plea of nolo contendere or its equivalent does not, of itself, create a presumption that the person (i) did not act in good faith and in a manner which he or she reasonably believed to be in, or not opposed to, the best interests of the corporation or (ii) with respect to any criminal action or proceeding, had reasonable cause to believe that his or her conduct was unlawful.

In the case of proceedings by or in the right of the corporation, the FBCA permits for indemnification of any person by reason of the fact that such person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of, such corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against liability incurred in connection with such proceeding, including appeals thereof; provided, however, that the officer, director, employee or agent acted in good faith and in a manner that he or she reasonably believed to be in, or not opposed to, the best interests of the corporation, except that no indemnification is made where such person is adjudged liable, unless a court of competent jurisdiction determines that, despite the adjudication of liability but in view of all circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which such court shall deem proper.

To the extent that such person is successful on the merits or otherwise in defending against any such proceeding, Florida law provides that he or she shall be indemnified against expenses actually and reasonably incurred by him or her in connection therewith.

Our Bylaws contain indemnification provisions similar to the FBCA, and further provide that we may purchase and maintain insurance on behalf of directors, officers, employees and agents in their capacities as such, or serving at the request of the corporation, against any liabilities asserted against such persons whether or not we would have the power to indemnify such persons against such liability under our Bylaws.

Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended, may be permitted to our directors, officers and controlling persons pursuant to the foregoing provisions, or otherwise, we have been advised that, in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

(b) Financial Statement Schedules

None. All other schedules for which provision is made in Regulation S-X of the Securities and Exchange Commission are not required under the related restrictions or are inapplicable, and, therefore, have been omitted.

Furnished as Appendix B to the proxy statement/prospectus, which forms a part of this Registration Statement on Form S-4.

Item 22. Undertakings.

The undersigned registrant hereby undertakes to file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

(i)

To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii)

To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective Registration Statement; and

(iii)

To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

The undersigned registrant hereby undertakes that, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

The undersigned registrant hereby undertakes to remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934, as amended (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

The undersigned registrant hereby undertakes as follows: that prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form.

The registrant undertakes that every prospectus (i) that is filed pursuant to the immediately preceding paragraph, or (ii) that purports to meet the requirements of Section 10(a)(3) of the Act and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed

II-3

TABLE OF CONTENTS

to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

The undersigned registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11 or 13 of this Form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

The undersigned registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.
