SUBJECT TO COMPLETION, DATED OCTOBER 4, 2022

PRELIMINARY PROXY STATEMENT/PROSPECTUS

PROPOSED MERGER — YOUR VOTE IS VERY IMPORTANT

To the Shareholders of Professional Holding Corp.:

On August 7, 2022, Seacoast Banking Corporation of Florida, or Seacoast, Seacoast National Bank, or SNB, Professional Holding Corp., or Professional, and Professional Bank entered into an Agreement and Plan of Merger (which we refer to as the “merger agreement”) that provides for the combination of Seacoast and Professional and their two banks. Under the merger agreement, Professional will merge with and into Seacoast, with Seacoast as the surviving corporation (which we refer to as the “merger”). Immediately following the merger, Professional Bank will merge with and into SNB, with SNB as the surviving bank (which we refer to as the “bank merger”). The proposed transaction will expand Seacoast’s footprint in the dynamic tri-county South Florida market, which includes Miami-Dade, Broward, and Palm Beach counties, the largest MSA in Florida and the eighth largest in the nation.

In the merger, each share of Professional common stock (except for specified shares of Professional common stock held by Professional, Professional Bank, Seacoast or SNB) will be converted into the right to receive 0.8909 of a share of Seacoast common stock (the “exchange ratio”), subject to the payment of cash in lieu of fractional shares (the “merger consideration”).

In the event that, as of the close of business on the fifth business day prior to completion of the merger, Professional’s consolidated tangible shareholders’ equity is less than $224.50 million or Professional Bank’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 exchange ratio used to calculate the merger consideration downward or terminate the merger agreement.

The market value of the per share stock consideration will fluctuate with the market price of Seacoast common stock and other factors and will not be known at the time Professional shareholders vote on the merger agreement. Based on the closing price of Seacoast’s common stock on the NASDAQ Global Select Market on            , 2022, the last practicable date before the date of this document, the value of the per share merger consideration payable to holders of Professional common stock was approximately $      . We urge you to obtain current market quotations for Seacoast (trading symbol “SBCF”).

Based on the current number of shares of Professional common stock outstanding, Seacoast expects to issue up to [12,871,842] shares of common stock to Professional shareholders upon completion of the merger. Immediately following completion of the merger, current Professional shareholders will own approximately 15.3% of the common stock of Seacoast. However, any increase or decrease in the number of shares of Professional 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.

Professional will hold a special meeting of its shareholders in connection with the merger. Holders of Professional common stock will be asked to vote to approve the merger agreement and related matters as described in this proxy statement/prospectus.

The special meeting of Professional shareholders will be held on            , 2022 at [•], located at [•], at [•] local time.

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

This document, which serves as a proxy statement for the special meeting of Professional shareholders and as a prospectus for the shares of Seacoast common stock to be issued in the merger to Professional shareholders, describes the special meeting of Professional, the merger, the documents related to the merger and other related matters. 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 and Professional from documents that each has filed with the Securities and Exchange Commission.

Professional shareholders who have questions about the merger should contact Michael C. Sontag at the address or telephone number shown under “Where You Can Find More Information” below.

Herbert Martens
Chairman
Professional Holding Corp.

Neither the Securities and Exchange Commission, the Board of Governors of the Federal Reserve System, the Office of the Comptroller of the Currency, the Federal Deposit Insurance Corporation, nor any state securities commission or any other bank regulatory agency has approved or disapproved the merger, the issuance of the Seacoast common stock to be issued in the merger, or the other transactions described in this document or passed upon the adequacy or accuracy of this proxy statement/prospectus. Any representation to the contrary is a criminal offense.

The securities to be issued in the merger are not savings or deposit accounts or other obligations of any bank or non-bank subsidiary of either Seacoast or Professional, and they are not insured by the Federal Deposit Insurance Corporation or any other governmental agency.

The date of this proxy statement/prospectus is            , 2022, and it is first being mailed or otherwise delivered to the shareholders of Professional on or about            , 2022.

NOTICE OF SPECIAL MEETING OF SHAREHOLDERS
TO BE HELD ON          , 2022

To the Shareholders of Professional Holding Corp.:

Professional Holding Corp. (“Professional”) will hold a special meeting of shareholders at     local time, on          , 2022, at          ,           , Florida          , for the following purposes:

•

for holders of Professional common stock to consider and vote upon a proposal to approve the Agreement and Plan of Merger, dated as of August 7, 2022, by and among Seacoast Banking Corporation of Florida, Seacoast National Bank, Professional Holding Corp. and Professional Bank, pursuant to which Professional will merge with and into Seacoast Banking Corporation of Florida and Professional Bank will merge with and into Seacoast National Bank, as more fully described in the attached proxy statement/prospectus; and

•

for holders of Professional common stock to consider and vote upon a proposal to adjourn the Professional special meeting, if necessary or appropriate, to solicit additional proxies in favor of the proposal to approve the merger agreement.

We have fixed the close of business on         , 2022 as the record date for the Professional special meeting. Only holders of record of Professional common stock at that time are entitled to notice of, and to vote at, the Professional special meeting, or any adjournment or postponement of the Professional special meeting. In order for the merger agreement to be approved, a majority of the holders of the outstanding shares of Professional common stock entitled to vote must vote in favor of the proposal to approve the merger agreement. The special meeting may be adjourned from time to time upon approval of holders of Professional common stock without notice other than by announcement at the meeting of the adjournment thereof, and any and all business for which notices hereby given may be transacted at such adjourned meeting.

Holders of Professional common stock are not entitled to appraisal or dissenters’ rights with respect to the merger under Section 607.1302 of the Florida Business Corporation Act.

Your vote is very important.   We cannot complete the merger unless Professional’s shareholders approve the merger agreement.

[We expect to hold the Professional special meeting in person, but we continue to monitor the situation regarding COVID-19 closely. Accordingly, we are planning for the possibility that the Professional special meeting may be held virtually or in person but subject to special precautions, including limitations on the number of participants in one room or other limitations. In that regard, only Professional shareholders as of            2022, the record date for the special meeting, will be admitted to the special meeting. No guests will be permitted.]

Regardless of whether you plan to attend the Professional special meeting, please vote as soon as possible. If you hold stock in your name as a shareholder of record, please complete, sign, date and return the accompanying proxy card in the enclosed postage-paid return envelope as described on the proxy card. If you hold your stock in “street name” through a bank, broker, or other nominee, please follow the instructions on the voting instruction card furnished by the record holder.

QUESTIONS AND ANSWERS ABOUT THE MERGER AND THE SPECIAL MEETING

The following are answers to certain questions that you may have regarding the special 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 Professional Holding Corp. as “Professional.”

Q:

Why am I receiving this proxy statement/prospectus?

A:

Seacoast, SNB, Professional, and Professional Bank have entered into an Agreement and Plan of Merger, dated as of August 7, 2022 (which we refer to as the “merger agreement”), pursuant to which Professional will merge with and into Seacoast, with Seacoast continuing as the surviving company. Immediately following the merger, Professional Bank, a wholly owned bank subsidiary of Professional, 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 “bank 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 a majority of the outstanding shares of Professional common stock entitled to vote in favor of the proposal to approve the merger agreement.

Professional will hold a special meeting to obtain this approval. This proxy statement/prospectus contains important information about the merger and another proposal being voted on at the special meeting, and you should read it carefully. It is a proxy statement because Professional’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 Professional common stock in connection with the merger. The enclosed materials allow you to have your shares voted by proxy without attending the Professional meeting. Your vote is important. We encourage you to submit your proxy as soon as possible.

Q:

What will I receive in the merger?

A:

If the merger is completed, for each share of Professional common stock that you hold immediately prior to the effective time of the merger, you will receive 0.8909 shares of Seacoast common stock, which we refer to as the exchange ratio. In the event that, as of the close of business on the fifth business day prior to completion of the merger, Professional’s consolidated tangible shareholders’ equity is less than $224.50 million or Professional Bank’s general allowance for loan and lease losses is less than 0.75% of total loans and leases outstanding, then Seacoast shall have the option to adjust the exchange ratio used to calculate the merger consideration downward or terminate the merger agreement.

Seacoast will not issue any fractional shares of Seacoast common stock in the merger. Rather, Professional 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 ten (10) trading days ending on the trading day immediately prior to the determination date. The determination date 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 Professional shareholder approval is obtained.

Q:

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

A:

Yes, because the exchange ratio is fixed, 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

1

Seacoast common stock after the date of this proxy statement/prospectus will change the value of the shares of Seacoast common stock that Professional shareholders will receive.

Q:

How does Professional’s board of directors recommend that I vote at the special meeting?

A:

Professional’s board of directors unanimously recommends that you vote “FOR” the proposal to approve the merger agreement and “FOR” the adjournment proposal.

Q:

When and where is the special meeting?

A:

The Professional special meeting will be held at [•], located at [•], [•], Florida, [•], on , 2022, at local time. [We expect to hold the Professional special meeting in person, but we continue to monitor the situation regarding COVID-19 closely. Accordingly, we are planning for the possibility that the Professional special meeting may be held virtually or in person but subject to special precautions, including limitations on the number of participants in one room or other limitations. In that regard, only Professional shareholders as of             2022, the record date for the special meeting, will be admitted to the special meeting. No guests will be permitted.]

Q:

Who can vote at the special meeting of shareholders?

A:

Holders of record of Professional common stock at the close of business on       , 2022, which is the date that the Professional board of directors has fixed as the record date for the special meeting, are entitled to vote at the special meeting.

Q:

What do I need to do now?

A:

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 special meeting. 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 special meeting will need to obtain a proxy form from the institution that holds their shares.

Q:

What constitutes a quorum for the special meeting?

A:

The presence at the special meeting, in person or by proxy, of holders of a majority of the outstanding shares of Professional 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.

Q:

What is the vote required to approve each proposal?

A:

Approval of the merger agreement requires the affirmative vote of the holders of a majority of the outstanding shares of Professional common stock entitled to vote on the merger agreement as of the close of business on       , 2022, the record date for the special meeting. If you (1) fail to submit a proxy or vote in person at the special 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 proposal.

The adjournment proposal will be approved if the votes of Professional common stock cast in favor of the adjournment proposal exceed the votes cast against the adjournment proposal. If you (1) fail to submit a proxy or vote in person at the special meeting, or (2) mark “ABSTAIN” on your proxy, it will have no effect on the adjournment proposal.

Q:

Why is my vote important?

A:

If you do not submit a proxy or vote in person, it may be more difficult for Professional to obtain the necessary quorum to hold its special meeting. In addition, your failure to submit a proxy or vote in person, or your abstention, will have the same effect as a vote against approval of the merger

2

agreement. The merger agreement must be approved by the affirmative vote of a majority of the outstanding shares of Professional common stock entitled to vote on the merger agreement. Professional’s board of directors unanimously recommends that you vote “FOR” the proposal to approve the merger agreement.

Q:

How many votes do I have?

A:

You are entitled to one vote for each share of Professional common stock that you owned as of the close of business on the record date.

Q:

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

A:

Yes. In considering the recommendation of Professional’s board of directors with respect to the merger agreement, you should be aware that some of Professional’s directors and executive officers have interests in the merger that are different from, or in addition to, the interests of Professional’s shareholders generally. Interests of certain officers and directors that may be different from or in addition to the interests of Professional’s shareholders include but are not limited to the receipt of continued indemnification and insurance coverage under the merger agreement and the payment of change in control payments or other compensation to certain executives.

Q:

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?

A:

No. Your bank, broker, or other nominee cannot vote your shares without instructions from you. You should instruct your bank, broker, or other nominee how to vote your shares in accordance with the instructions provided to you. Please check the voting form used by your bank, broker, or other nominee.

Q:

What if I abstain from voting or fail to instruct my bank, broker, or other nominee?

If you (1) fail to submit a proxy or vote in person at the special 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 proposal. If you (1) fail to submit a proxy or vote in person at the special 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 adjournment proposal, it will have no effect on the adjournment proposal.

[Q:

Can I attend the special meeting and vote my shares in person?

A:

Yes. All Professional shareholders, including shareholders of record and shareholders who hold their shares through nominees or other holders of record, are invited to attend the special meeting.

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.” Holders of Professional 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, holders of Professional common stock may recognize gain or loss on any cash received instead of a fractional share of Seacoast common stock assuming that the cash received is not treated as a dividend.

The closing of the Professional, Apollo and Drummond mergers are not conditioned on the closing of any of the other mergers.

Agreement and Plan of Merger with Drummond Banking Company

On May 4, 2022, Seacoast announced that Seacoast and SNB had entered into an agreement and plan of merger with Drummond Banking Company, a Florida corporation (“Drummond”).

The closing of the Professional, Apollo and Drummond mergers are not conditioned on the closing of any of the other mergers.

Regulatory Approvals

Completion of the merger and the bank merger are subject to various regulatory approvals, including approvals from the Federal Reserve and the Office of the Controller of the Currency, which we refer to as the OCC. Notifications and/or applications requesting approvals for the merger or for the bank 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 Federal Reserve and the OCC. The parties cannot be certain when or if they will obtain approval from the Federal Reserve and 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. The regulatory approvals to which the completion of the merger and bank 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, Professional will merge with and into Seacoast, with Seacoast as the surviving entity of such merger, and Professional Bank will merge with and into SNB, with SNB as the surviving bank of such

7

bank merger. The merger of Professional Bank with and into SNB shall occur immediately following the merger of Professional with and into Seacoast, unless otherwise determined by Seacoast in its sole discretion.

Closing and Effective Time of the Merger (see page   )

The closing date is currently expected to occur in the first quarter of 2023. Simultaneously with the closing of the merger, Seacoast will file articles of merger with the Secretary of State of the State of Florida. The merger will become effective at such time as the articles of merger are filed or such other time as may be specified in the articles of merger. The parties have agreed to use their reasonable best efforts to cause the effective time to occur on or before February 28, 2023 (provided that, if such date is not practicable, the parties will cause the effective time to occur on a mutually agreeable date within ten business days following the satisfaction or waiver of the closing conditions). Neither Seacoast nor Professional 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 Professional shareholders’ approvals will be received.

Merger Consideration (see page   )

Under the terms of the merger agreement, each share of Professional common stock (excluding certain shares held by Seacoast, Professional, Professional Bank, SNB and their wholly owned subsidiaries) will be converted into the right to receive 0.8909 shares of Seacoast common stock, which we refer to as the “exchange ratio.” Please see “The Merger Agreement — Consideration” on page   for more information.

If, as of the close of business on the fifth business day prior to completion of the merger, Professional’s consolidated tangible shareholders’ equity is less than $224.50 million or Professional Bank’s general allowance for loan and lease losses is less than 0.75% of total loans and leases outstanding (excluding loans originated under the PPP), then Seacoast shall have the option to adjust the exchange ratio used to calculate the merger consideration downward or terminate the merger agreement.

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 ten (10) 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 Professional shareholder approval is obtained.

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 August 5, 2022, the last business day prior to the date of the signing of the merger agreement, the value of the per share stock consideration payable to holders of Professional common stock was approximately $32.74 per share. Based on the closing price of Seacoast common stock on         , 2022, the last practicable date before the date of this document, the value of the per share stock consideration payable to holders of Professional common stock was approximately $      . Professional shareholders should obtain current sale prices for Seacoast common stock, which is traded on the NASDAQ Global Select Market under the symbol “SBCF.”

Equivalent Professional Common Stock Per Share Value (see page   )

Seacoast common stock trades on the NASDAQ Global Select Market under the symbol “SBCF.” The following table presents the closing price of Seacoast common stock on August 5, 2022, the last trading date prior to the public announcement of the merger agreement, and         , 2022, 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 Professional common stock on those dates, calculated by multiplying the closing sale price of Seacoast common stock on those dates by the exchange ratio of 0.8909.

Date	Seacoast closing sale price			Equivalent Professional per share value
August 5, 2022	​	$	36.75	​	$	32.74
, 2022	​	$		​	$	​

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 per share merger consideration to be received by Professional shareholders. Similarly, if Seacoast shares decline in value, so will the value of the per share merger consideration to be received by Professional shareholders. Professional shareholders should obtain current sale prices for the Seacoast common stock.

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

Promptly 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 Professional 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 Professional 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. Accordingly, holders of Professional 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, holders of Professional common stock may recognize gain or loss on any cash received instead of a fractional share of Seacoast common stock assuming that the cash received is not treated as a dividend.

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

The U.S. federal income tax consequences described above may not apply to all holders of Professional 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.

Appraisal Rights (see page   )

Holders of Professional common stock are not entitled to appraisal or dissenters’ rights with respect to the merger under Section 607.1302 of the Florida Business Corporation Act.

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

Seacoast’s financial advisor, Piper Sandler & Co., (“Sandler”) has delivered a written opinion, dated August 5, 2022, to the board of directors of Seacoast to the effect that, as of such date, and based upon and subject to the assumptions made, matters considered, qualifications and limitations on the review undertaken by Piper Sandler, as stated in the opinion, the merger consideration was fair, from a financial point of view, to Seacoast. The full text of Piper Sandler’s opinion is attached to this proxy statement/​prospectus as Appendix B. The opinion outlines the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by Piper Sandler in rendering its opinion. Holders of Seacoast common stock are urged to read the entire opinion carefully in connection with their consideration of the proposed merger. Piper Sandler’s opinion was directed to the board of directors of Seacoast in connection with its consideration of the merger and the merger agreement and does not constitute a recommendation to any shareholder of Seacoast as to how any such shareholder should vote at any meeting of shareholders called to consider and vote upon the approval of the merger and the merger

9

agreement. Piper Sandler’s opinion was directed only to the fairness, from a financial point of view, of the merger consideration to Seacoast and did not address the underlying business decision of Seacoast to engage in the merger, the form or structure of the merger or any other transactions contemplated in the merger agreement, the relative merits of the merger as compared to any other alternative transactions or business strategies that might exist for Seacoast or the effect of any other transaction in which Seacoast might engage.

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

Opinion of Professional’s Financial Advisor (see page   and Appendix C)

Professional’s financial advisor, Stephens Inc. (“Stephens”), has delivered a written opinion, dated August 5, 2022, to the board of directors of Professional that, as of such date, and based upon and subject to certain matters stated in the opinion, the total value to be received by the shareholders of Professional in connection with the merger is fair, from a financial point of view, to Professional shareholders. We have attached this opinion to this proxy statement/prospectus as Appendix C. The opinion of Stephens is not a recommendation to any Professional shareholder as to how to vote on the proposal to approve the merger agreement. You should read this opinion completely to understand the procedures followed, matters considered and limitations and qualifications on the reviews undertaken by Stephens in providing its opinion.

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

Recommendation of the Professional Board of Directors (see page   )

After careful consideration, the Professional board of directors unanimously recommends that Professional shareholders vote “FOR” the approval of the merger agreement and “FOR” the approval of the adjournment proposal described in this document. Certain of the directors and officers of Professional who as of the date of the merger agreement held shares of Professional 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, subject to the terms of the shareholder support agreement.

For more information regarding the shareholder support agreement, please see the section entitled “Information About the Professional Special Meeting — Shares Subject to Shareholder Support Agreement; Shares Held by Directors and Executive Officers” beginning on page   .

For a more complete description of Professional’s reasons for the merger and the recommendations of the Professional board of directors, please see the section entitled “The Merger — Professional’s Reasons for the Merger and Recommendation of Professional’s Board of Directors” beginning on page   .

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

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

•

Professional’s directors and executive officers are entitled to continued indemnification and insurance coverage under the merger agreement.

•

The merger agreement provides for the issuance of substitute Seacoast options in exchange for Professional options, the accelerated vesting of all Professional restricted stock awards, and the accelerated vesting and exercise of all Professional stock appreciation rights.

•

Certain Professional executives are entitled to bonuses upon a change of control of Professional pursuant to their current employment and change in control agreements.

•

Abel Iglesias, Ryan Gorney, and Mary Usategui have each entered into an employment agreement with Seacoast, effective as of the effective date of the merger.

10

These interests are discussed in more detail in the section entitled “The Merger — Interests of Professional Directors and Executive Officers in the Merger” beginning on page   . The Professional board of directors was aware of the different or additional interests set forth herein and considered such interests along with other matters in adopting and approving the merger agreement and the transactions contemplated thereby, including the merger.

Treatment of Professional Equity Awards (see page   )

The merger agreement requires Professional to take all actions necessary to cause each Professional equity award issued and outstanding immediately prior to the effective time to become fully vested and to be terminated at the effective time of the merger. In consideration of such termination, Seacoast will grant to each holder of Professional 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 Professional 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 Professional common stock subject to such Professional 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 Professional common stock at which such Professional option was exercisable immediately prior to the effective time by (y) the exchange ratio, rounded up to the nearest whole cent.

At the effective time of the merger, each share of Professional common stock that is subject to a Professional restricted stock award that is outstanding immediately prior to the effective time shall, by virtue of the merger, automatically be vested and converted into the right to receive the merger consideration.

Prior to the effective time of the merger, Professional shall cause each Professional stock appreciation right that is outstanding to be vested and exercised for a number of shares of Professional common stock determined pursuant to the terms of the applicable stock appreciation right award agreement, subject to applicable withholding. At the effective time, each share of Professional common stock issuable as a result of such exercise of Professional stock appreciation rights shall, by virtue of the merger, automatically be vested and converted into the right to receive the merger consideration.

by the board of directors of Professional during the five-day period commencing on the determination date (defined in the merger agreement as the later of: (i) the date on which the last required consent is obtained without regard to any requisite waiting period; or (ii) the date on which Professional shareholder approval is obtained), if and only if (a) the buyer ratio (defined in the merger agreement to mean the number obtained by dividing the average closing price (defined in the merger agreement to mean the daily volume weighted average price of Seacoast common stock) during the ten (10) consecutive full trading days ending on the trading day prior to the determination date by $36.75) is less than 0.85 and (b) the buyer ratio is less than the number obtained by (i) dividing the average of the index price (defined in the merger agreement to mean the closing price on any given trading day) for the ten (10) consecutive trading days preceding the determination date by the average of the index price for the ten (10) consecutive trading days ending on the last trading day immediately preceding the date of the first public announcement of the entry into the merger agreement and (ii) subtracting 0.20 from the quotient.

Termination Fee (see page   )

Professional must pay Seacoast a termination fee of $21.79 million if:

•

(i) either party terminates the merger agreement in the event that approval by the shareholders of Professional is not obtained at a meeting at which a vote was taken; or (ii) Seacoast terminates the merger agreement (a) as a result of a willful breach of a covenant or agreement by Professional; (b) because Professional has withdrawn, qualified or modified its recommendation to shareholders in a manner adverse to Seacoast; or (c) because Professional has failed to substantially comply with the no-shop covenant or its obligations under the merger agreement by failing to hold a special meeting of Professional shareholders; and (1) Professional receives or there is a publicly announced third party acquisition proposal that has not been formally withdrawn or abandoned prior to the termination of the merger agreement; and (2) within 12 months of the termination of the merger agreement, Professional either consummates a third party acquisition proposal or enters into a definitive agreement with respect to a third party acquisition proposal; or

•

Seacoast terminates the merger agreement as a result of the board of directors of Professional recommending, endorsing, accepting or agreeing to a third-party acquisition proposal; or

•

Professional terminates the merger agreement because the board of directors of Professional has determined in accordance with the provisions in the merger agreement relating to acquisition proposals that a superior proposal has been made and has not been withdrawn and none of Professional or its representatives has failed to comply in all material respects with the terms of merger agreement relating to third party acquisition proposals.

Except in the case of a breach of the merger agreement, the payment of the termination fee will fully discharge Professional and Professional Bank from any losses that may be suffered by Seacoast arising out of the termination of the merger agreement, and in no event will Professional be required to pay the termination fee on more than one occasion.

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.

Any further dividends paid on Seacoast’s common stock would 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.

Comparison of Shareholders’ Rights (see page   )

The rights of Professional shareholders who continue as Seacoast shareholders after the merger will be governed by the articles of incorporation and bylaws of Seacoast rather than the articles of incorporation and bylaws of Professional. For more information, please see the section entitled “Comparison of Shareholders’ Rights” beginning on page   .

Risk Factors (see page   )

Before voting at the Professional special 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   .

RISK FACTORS

An investment by Professional’s shareholders in Seacoast common stock as a result of the exchange of shares of Professional common stock for shares of Seacoast common stock in the merger involves certain risks. Certain material risks and uncertainties connected with the merger agreement, including the merger and bank merger, and ownership of Seacoast common stock are discussed below. In addition, Seacoast and Professional discuss certain other material risks connected with the ownership of Seacoast common stock and with Seacoast’s business, and with the ownership of Professional common stock and Professional’s business, respectively, under the caption “Risk Factors” appearing in their respective Annual Reports on Form 10-K most recently filed with the SEC and may include additional or updated disclosures of such material risks in their subsequent Quarterly Reports on Form 10-Q and Current Reports on Form 8-K that have been filed with the SEC or may be filed with the SEC after the date of this proxy statement/prospectus, each of which reports is or will be incorporated by reference in this proxy statement/prospectus.

Holders of Professional common stock should carefully read and consider all of these risks and all other information contained in this proxy statement/prospectus, including the discussions of risk factors included in the documents incorporated by reference in this proxy statement/prospectus, in deciding whether to vote for approval of the proposals on which they may be entitled to vote at the special meeting described herein. The risks described in this proxy statement/prospectus and in those documents incorporated by reference may adversely affect the value of Seacoast common stock that you, as an existing Professional shareholder, will hold upon the completion of the merger, and could result in a significant decline in the value of Seacoast common stock and cause the holders of Professional common stock to lose all or part of their respective investments.

Risks Associated with the Merger

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

The businesses of Seacoast and Professional 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 Professional. 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” beginning on page   .

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 Professional common stock outstanding immediately prior to the effective time of the merger (excluding shares of Professional common stock owned by Professional, Seacoast, Professional Bank, or SNB) will be converted into the right to receive 0.8909 shares of Seacoast common stock (plus cash in lieu of fractional shares), which is subject to adjustment based on the value of Professional’s consolidated tangible shareholders’ equity. The value of the shares of Seacoast common stock to be issued to Professional 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 Professional. We make no assurances as to whether or when the merger will be completed. Professional shareholders should obtain current sale prices for shares of Seacoast common stock before voting their shares of Professional common stock at the special meeting.

The merger will not be completed unless important conditions are satisfied or waived, including approval by Professional 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 Professional may lose some or all

17

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 Professional are obligated to complete the merger:

•

The merger agreement and the transactions contemplated thereby must have been approved by the affirmative vote of a majority of the outstanding voting shares of Professional 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 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 SNB, 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 be continuing;

•

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 directors and executives of Professional and Professional Bank shall have entered into claims letters and/or restrictive covenant agreements;

•

Professional’s consolidated tangible shareholders’ equity as of the close of business on the fifth business day prior to the closing date shall not be less than $224.50 million, less the impact of after-tax permitted expenses, and Professional Bank’s general allowance for loan and lease losses shall not be less than 0.75% of total loans and leases outstanding (excluding loans originated under the PPP);

•

Seacoast 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 NASDAQ, and the shares of Seacoast common stock to be issued upon the exercise of substitute Seacoast options shall have been reserved for issuance and approved for listing on 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 Professional common stock as a result of the merger will have rights different from the shares of Professional common stock.

Upon completion of the merger, the rights of former Professional shareholders will be governed by the articles of incorporation, as amended, and bylaws of Seacoast. The rights associated with Professional 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.

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

Professional shareholders currently have the right to vote in the election of the board of directors of Professional and on other matters affecting Professional. Upon the completion of the merger, Professional’s shareholders will be shareholders of Seacoast with a percentage ownership of Seacoast that is smaller than such shareholders’ current percentage ownership of Professional. It is currently expected that the former shareholders of Professional as a group will receive shares in the merger constituting approximately

18

[15.3]% of the outstanding shares of the combined company’s common stock immediately after the merger. Because of this, Professional shareholders will have less influence on the management and policies of the combined company than they now have on the management and policies of Professional.

Holders of Professional common stock will not have appraisal rights or dissenters’ rights in the merger.

Appraisal rights (also known as dissenters’ rights) are statutory rights that, if applicable under law, enable shareholders to dissent from an extraordinary transaction, such as a merger, and to demand that the corporation pay the fair value for their shares as determined by a court in a judicial proceeding instead of receiving the consideration offered to shareholders in connection with the extraordinary transaction.

Under Section 607.1302 of the FBCA, the holders of Professional common stock will not be entitled to appraisal or dissenters’ rights in connection with the merger if, on the record date for the Professional special meeting, Professional’s shares are listed on a national securities exchange. Professional common stock is currently listed on the NASDAQ, a national securities exchange, and is expected to continue to be so listed on the record date for the Professional special meeting. In addition, the holders of Professional common stock will receive shares of Seacoast common stock as consideration in the merger, which shares are currently listed on the NASDAQ, and are expected to continue to be so listed at the effective time. Accordingly, the holders of Professional common stock are not entitled to any appraisal or dissenters’ rights in connection with the merger.

The unaudited pro forma combined condensed financial information included in this proxy statement/​prospectus is preliminary and the actual financial condition and results of operations of the combined company after the merger may differ materially.

The unaudited pro forma combined condensed financial information in this proxy statement/​prospectus is presented for illustrative purposes only and is not necessarily indicative of what the combined company’s actual financial condition or results of operations would have been had the merger been completed on the dates indicated. The unaudited pro forma combined condensed financial information reflects adjustments, which are based upon preliminary estimates, to record the Professional identifiable assets acquired and liabilities assumed by Seacoast at fair value and the resulting goodwill recognized. The fair value estimates reflected in this proxy statement/prospectus are preliminary, and final amounts will be based upon the actual consideration and the fair value of the assets and liabilities of Professional as of the date of the completion of the merger. Accordingly, the final acquisition accounting adjustments may differ materially from the pro forma adjustments reflected in this proxy statement/prospectus. For more information, see the section entitled “Unaudited Pro Forma Condensed Combined Financial Information” beginning on page    .

Seacoast and Professional 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 Professional and Seacoast. These uncertainties may impair Seacoast’s or Professional’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 Professional to seek to change existing business relationships with Seacoast or Professional or fail to continue existing relationships. In addition, competitors may target each party’s existing customers by highlighting potential uncertainties and integration difficulties that may result from the merger.

Each of Seacoast and Professional has a small number of key personnel. The pursuit of the merger and the preparation for the integration of the two companies following the merger 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.

19

In addition, the merger agreement restricts Professional from taking certain actions without Seacoast’s consent while the merger is pending. These restrictions may, among other matters, prevent Professional 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 Professional’s business prior to consummation of the merger or termination of the merger agreement. These restrictions could have a material adverse effect on Professional’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 Professional 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 integrated, it is possible that the estimates of the potential cost savings could turn out to be incorrect. For example, the combined purchasing power may not be as strong as expected, and therefore the cost savings could be reduced. In addition, 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 Professional 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 Professional. Although Seacoast and Professional 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 Professional and Seacoast will incur or have incurred substantial expenses in connection with the negotiation and completion of the transactions contemplated by the merger agreement. If the merger is not completed, Seacoast and Professional would have to recognize these expenses without realizing the anticipated benefits of the merger.

Seacoast and Professional 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, and 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. This tax opinion represents 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 Professional common stock will recognize any gain with respect to the entire consideration received in the merger, including any shares of Seacoast stock received as well as any cash received in lieu of fractional shares of Seacoast common stock. The consequences of the merger to any particular Professional shareholder will

20

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 may 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 fairness opinion of Professional’s financial advisor and Seacoast’s financial advisor will not reflect changes in circumstances between the date of the opinion and the completion of the merger.

Professional’s board of directors received an opinion from its financial advisor to address the fairness of the merger consideration, from a financial point of view, to the holders of Professional’s common stock as of August 5, 2022, and Seacoast’s board of directors received an opinion from its financial advisor to address the fairness of the merger consideration, from a financial point of view, to the holders of Seacoast’s common stock as of August 5, 2022. Subsequent changes in the operation and prospects of Seacoast or Professional, general market and economic conditions and other factors that may be beyond the control of Seacoast or Professional, and on which Professional’s and Seacoast’s respective financial advisors’ opinions were based, may significantly alter the value of Seacoast or the price of the shares of Seacoast common stock by the time the merger is completed. Because neither Seacoast’s nor Professional’s respective advisors are expected to update their respective opinions, neither opinion will address the fairness of the merger consideration 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 that Professional received from its financial advisor, please refer to the section entitled “The Merger — Opinion of Professional’s Financial Advisor” beginning on page    . For a description of the opinion that Seacoast received from its financial advisor, please refer to the section entitled “The Merger — Opinion of Seacoast’s Financial Advisor” beginning on page    .

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

The board of directors of and certain executive officers of Professional negotiated the terms of the merger agreement with Seacoast, and the Professional board of directors unanimously approved and recommended that Professional 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 Professional executive officers and directors have financial interests in the merger that are different from, or in addition to, the interests of Professional shareholders generally. See “The Merger — Interests of Professional 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 Professional.

Until the completion of the merger, with some limited exceptions, Professional is prohibited from soliciting, initiating, encouraging or participating in any discussion concerning a proposal to acquire Professional, such as a merger or other business combination transaction, with any person other than Seacoast. In addition, Professional has agreed to pay to Seacoast in certain circumstances a termination fee equal to $21.79 million. These provisions could discourage other companies from trying to acquire Professional even though those other companies might be willing to offer greater value to Professional

21

shareholders than the consideration to be paid in the merger. The payment of any termination fee could also have an adverse effect on Professional’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 Professional.

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 mergers with Drummond and/or Apollo are not completed, Seacoast will have incurred substantial expenses without realizing the expected benefits of the mergers.

Seacoast has incurred and will incur substantial non-recurring expenses in connection with the negotiation and completion of the transactions contemplated by the merger agreements with Drummond and Apollo, respectively. While Seacoast has assumed that a certain level of expenses would be incurred in connection with those mergers, there are many factors beyond its control that could affect the total amount of expenses associated with those mergers. If the mergers are not completed, Seacoast will have to recognize these expenses without realizing the expected benefits of the merger.

Some of the performing loans in the Professional loan portfolio being acquired by Seacoast may be under-collateralized, which could affect Seacoast’s ability to collect all of the loan amounts 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 Professional loan portfolio, Seacoast has preliminarily estimated a $40.2 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 Professional 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.

Sales of substantial amounts of Seacoast common stock in the open market by former Professional shareholders could depress Seacoast’s stock price.

Shares of Seacoast common stock that are issued to Professional shareholders in the merger will be freely tradable without restrictions or further registration under the Securities Act, except that shares of Seacoast common stock 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. Based on the number of shares of Professional common stock outstanding as of the Professional record date, Seacoast currently expects to issue 12,871,842 shares of Seacoast common stock in connection with the merger. If the merger is completed and if former shareholders of Professional sell substantial amounts of Seacoast common stock in the public market following completion of the merger, the market price of Seacoast common stock may decrease. These sales might also make it more difficult for Seacoast to sell equity or equity-related securities at a time and price that it otherwise would deem appropriate.

22

Litigation may be filed against the board of directors of Seacoast or Professional that could prevent or delay the completion of the merger or result in the payment of damages following completion of the merger.

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

Certain statements contained in this proxy statement/prospectus, including statements included or incorporated by reference in this proxy statement/prospectus, are not statements of historical fact and constitute “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, and are intended to be protected by the safe harbor provided by that Act. These statements are subject to risks and uncertainties and include information about possible or assumed future results of operations of Seacoast after the merger is completed, as well as information about the merger. Words such as “believes,” “expects,” “anticipates,” “estimates,” “intends,” “would,” “continue,” “should,” “may,” or similar expressions, or the negatives thereof, are intended to identify forward-looking statements, but are not the exclusive means of identifying such statements. Many possible events or factors could affect the future financial results and performance of each of Seacoast and Professional before the merger or Seacoast after the merger, and could cause those results or performance to differ materially from those expressed in the forward-looking statements. These possible events or factors include, but are not limited to:

•

general business and economic conditions, either globally, nationally, in the State of Florida, or in the specific markets in which Seacoast or Professional operate, including the negative impacts and disruptions resulting from rising interest rates, supply chain challenges and inflation, which have had and may likely continue to have an adverse impact on our business operations and performance, and could continue to have a negative impact on our credit portfolio, stock price, borrowers and the economy as a whole both globally and domestically;

•

the impact of Hurricane Ian on Florida generally, as well as certain of the communities we serve, and which could continue to have a negative impact on our business, credit portfolio, borrowers and our stock price;

•

the failure to obtain the approval of Professional shareholders in connection with the merger;

•

the risk that the merger may not be completed in a timely manner or at all, which may adversely affect Seacoast’s and Professional’s respective businesses and the price of their respective common stocks;

•

the risk that a condition to closing of the proposed merger may not be satisfied;

•

the risk that a required regulatory approval for the proposed merger is not obtained or is obtained subject to conditions that are not anticipated;

•

the parties’ ability to achieve the synergies and value creation contemplated by the proposed merger;

•

the parties’ ability to promptly and effectively integrate the businesses of Seacoast and Professional, including unexpected transaction costs, including the costs of integrating operations, severance, professional fees and other expenses;

•

the diversion of management time on issues related to the merger;

•

the occurrence of any event, change or other circumstance that could give rise to the termination of the merger agreement;

•

the effect of the announcement or pendency of the merger on Seacoast’s customer, employee and business relationships, operating results, and business generally;

•

deposit attrition, operating costs, customer loss and business disruption following the proposed merger, including difficulties in maintaining relationships with employees, may be greater than expected;

•

reputational risks and the reaction of the companies’ customers to the proposed merger;

•

customer acceptance of the combined company’s products and services;

•

increased competitive pressures and solicitations of customers and employees by competitors;

•

the failure to consummate or delay in consummating the merger for other reasons;

•

the outcome of any legal proceedings that may be instituted against Seacoast or Professional related to the merger agreement or the merger;

24

•

changes in laws or regulations;

•

the dilution caused by Seacoast’s issuance of additional shares of its common stock in the merger or related to the merger;

•

the sale price of Seacoast common stock could decline before the completion of the merger, including as a result of the financial performance of Seacoast or Professional or more generally due to broader stock market movements and the performance of financial companies and peer group companies;

•

changes in interest rates, deposit flows, loan demand and real estate values; and

•

the ongoing impacts and disruptions resulting from COVID-19 or other variants on the economies and communities we serve, which has had and may likely continue to have an adverse impact on our business operations and performance, and could continue to have a negative impact on our credit portfolio, stock price, borrowers and the economy as a whole both globally and domestically.

For additional information concerning factors that could cause actual conditions, events or results to materially differ from those described in the forward-looking statements, please refer to the “Risk Factors” section of this proxy statement/prospectus, as well as the factors set forth under the headings “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in each of Seacoast’s and Professional’s most recent Form 10-K and Form 10-Q reports, which are available online at www.sec.gov, and are incorporated by reference herein. No assurances can be given that any of the events anticipated by the forward-looking statements will transpire or occur, or if any of them do occur, what impact they will have on the results of operations or financial condition of Seacoast or Professional. You are cautioned not to place undue reliance on the forward-looking statements, which speak only as of the date of this proxy statement/prospectus or the dates of the documents incorporated by reference in this proxy statement/prospectus. As for the forward-looking statements that relate to future financial results and other projections, actual results will be different due to the inherent uncertainties of estimates, forecasts and projections and may be better or worse than projected and such differences could be material. Given these uncertainties, we caution you not to place reliance on these forward-looking statements. Annualized, pro forma, projected and estimated numbers are used for illustrative purpose only, are not forecasts and may not reflect actual results. The forward-looking statements are made as of the date of this proxy statement/​prospectus or the date of the applicable document incorporated by reference into this proxy statement/​prospectus.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

The following unaudited pro forma condensed combined financial information is based on the separate historical financial statements of Seacoast and Professional after giving effect to the merger, the issuance of Seacoast common stock in connection therewith, and the assumptions and adjustments described in the accompanying notes. The unaudited pro forma condensed combined balance sheet gives effect to the merger as if it had taken place on June 30, 2022. The unaudited pro forma condensed combined statements of income give effect to the merger as if it had taken place on January 1, 2021. This unaudited pro forma condensed combined financial information was prepared using the acquisition method of accounting where Seacoast is considered the acquirer of Professional for accounting purposes.

The following unaudited pro forma condensed combined financial information and related notes are based on and should be read in conjunction with (i) the historical audited consolidated financial statements of Seacoast and the related notes included in Seacoast’s Annual Report on Form 10-K for the year ended December 31, 2021, and the historical unaudited consolidated financial statements of Seacoast and the related notes included in Seacoast’s Quarterly Report on Form 10-Q for the period ended June 30, 2022, each of which is incorporated by reference herein, and (ii) the historical audited consolidated financial statements of Professional and the related notes included in Professional’s Annual Report on Form 10-K for the year ended December 31, 2021, and the historical unaudited consolidated financial statements of Professional and the related notes included in Professional’s Quarterly Report on Form 10-Q for the period ended June 30, 2022, each of which is incorporated by reference herein. The unaudited pro forma condensed combined statements of income for the year ended December 31, 2021 and for the six months ended June 30, 2022 give effect to Seacoast’s acquisitions of Business Bank of Florida Corp. (“BBFC”), Sabal Palm Bancorp, Inc. (“Sabal Palm”) each of which was consummated on January 3, 2022, and the acquisitions of Apollo Bancshares, Inc. (“Apollo”) and Drummond Banking Company (“Drummond”), each of which are expected to close early in the fourth quarter of 2022, all as if they had occurred on January 1, 2021. The Seacoast unaudited pro forma condensed combined balance sheet as of June 30, 2022 gives effect to Seacoast’s acquisitions of Apollo and Drummond, which are expected to close early in the fourth quarter of 2022, as if each had occurred on June 30, 2022.

The historical consolidated financial information has been adjusted in the unaudited pro forma condensed combined financial statements to give effect to pro forma events that are (i) directly attributable to the merger, (ii) factually supportable and (iii) with respect to the unaudited pro forma condensed combined statement of income, expected to have a continuing effect on the combined results of Seacoast and Professional. The unaudited pro forma condensed combined financial information contained herein does not reflect the costs of any integration activities or benefits that may result from the realization of future cost savings from operating efficiencies, or any other synergies that may result from the merger.

The following unaudited pro forma condensed combined financial statements give effect to the merger and include adjustments for the following:

•

Application of the acquisition method of accounting under the provisions of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 805, Business Combinations, to reflect estimated merger consideration of approximately $398.1 million (see note 2 herein) in exchange for all outstanding shares of Professional common stock, including adjustments for the conversion of Professional’s outstanding equity awards;

•

Direct transaction costs in connection with the merger.

The statements and related notes are being provided for illustrative purposes only and do not purport to represent what the combined company’s actual results of operations or financial position would have been had the merger been completed on the dates indicated, nor are they necessarily indicative of the combined company’s future results of operations or financial position for any future period.

As of the date of this joint proxy statement/prospectus, Seacoast has not completed the valuation analyses and calculations in sufficient detail necessary to arrive at the required estimates of the fair market value of the assets to be acquired or liabilities to be assumed from Professional, Apollo, or Drummond, other than a preliminary estimate for intangible assets and certain financial assets and financial liabilities. Accordingly, apart from the aforementioned, certain assets and liabilities of Professional, Apollo and

26

Drummond are presented at their respective carrying amounts and should be treated as preliminary values. A final determination of the fair value of these assets and liabilities will be based on the actual assets and liabilities as of the closing date and, therefore, cannot be made prior to the completion of the mergers. Actual adjustments may differ from the amounts reflected in the unaudited pro forma condensed combined financial statements, and the differences may be material.

Further, Seacoast has not identified all adjustments necessary to conform the accounting policies of Professional, Apollo and Drummond to Seacoast’s accounting policies. Upon completion of the mergers, or as more information becomes available, Seacoast will perform a more detailed review of the entities’ accounting policies. As a result of that review, differences could be identified between the accounting policies of Seacoast and the other companies that, when conformed, could have a material impact on the combined company’s financial information.

As a result of the foregoing, the pro forma adjustments are preliminary and are subject to change as additional information becomes available and as additional analysis is performed. The preliminary pro forma adjustments have been made solely for the purpose of providing the unaudited pro forma condensed combined financial statements. Seacoast estimated the fair value of certain Professional, Apollo, and Drummond assets and liabilities based on a preliminary valuation analysis, due diligence information, information presented in Professional’s SEC filings and other publicly available information. Until the merger is completed, each company is limited in their ability to share certain information.

The value of the merger consideration to be paid by Seacoast in each of the pending mergers will be determined based on the closing price of Seacoast common stock on the closing date, and the number of issued and outstanding shares of each of the acquired entities immediately prior to closing. The value of the shares of Seacoast common stock to be issued in each merger will fluctuate until the closing date due to a variety of factors, including general market and economic conditions, among other factors.

Upon completion of each merger, a final determination of the fair value of the assets acquired and liabilities assumed will be performed. Any changes in the fair values of the net assets or total purchase consideration as compared with the information shown in the unaudited pro forma condensed combined financial statements may change the amount of the total purchase consideration allocated to goodwill and other assets and liabilities and may impact the combined company’s statement of income. The final purchase consideration allocation may be materially different than the preliminary purchase consideration allocation presented in the unaudited pro forma condensed combined financial statements.

NOTES TO THE UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

Note 1 — Basis of pro forma presentation

The accompanying unaudited pro forma condensed combined financial statements and related notes were prepared in accordance with Article 11 of Regulation S-X. The unaudited pro forma condensed combined statements of income for the six months ended June 30, 2022 and for the year ended December 31, 2021 combine the historical consolidated statements of income of Seacoast and Professional, giving effect to the merger as if it had been completed on January 1, 2021. The accompanying unaudited pro forma condensed combined balance sheet as of June 30, 2022 combines the historical consolidated balance sheets of Seacoast and Professional, giving effect to the merger as if it had been completed on June 30, 2022.

Seacoast’s and Professional’s historical financial statements were prepared in accordance with U.S. GAAP. As discussed in Note 3, certain reclassifications were made to align Seacoast’s and Professional’s financial statement presentation. Seacoast has not identified all adjustments necessary to conform Professional’s accounting policies to Seacoast’s accounting policies. Upon completion of the merger, or as more information becomes available, Seacoast will perform a more detailed review of Professional’s accounting policies. As a result of that review, differences could be identified between the accounting policies of the two companies that, when conformed, could have a material impact on the combined company’s financial information.

The accompanying unaudited pro forma condensed combined financial statements and related notes were prepared using the acquisition method of accounting under the provisions of ASC Topic 805, with Seacoast considered the acquirer of Professional. ASC Topic 805 requires, among other things, that the assets acquired and liabilities assumed in a business combination be recognized at their fair values as of the acquisition date. For purposes of the unaudited pro forma condensed combined balance sheet, the purchase consideration has been allocated to the assets acquired and liabilities assumed of Professional based upon management’s preliminary estimate of their fair values as of June 30, 2022. Seacoast has not completed the valuation analysis and calculations in sufficient detail necessary to arrive at the required estimates of the fair market value of the Professional assets to be acquired or liabilities assumed, other than a preliminary estimate for intangible assets and certain financial assets and financial liabilities. Accordingly, apart from the aforementioned, certain Professional assets and liabilities are presented at their respective carrying amounts and should be treated as preliminary values. Any differences between the fair value of the consideration transferred and the fair value of the assets acquired and liabilities assumed will be recorded as goodwill. Accordingly, the purchase price allocation and related adjustments reflected in these unaudited pro forma condensed combined financial statements are preliminary and subject to revision based on a final determination of fair value.

The unaudited pro forma condensed combined financial statements include adjustments for nonrecurring estimated legal, investment banking, and other professional fees directly associated with the transactions. These costs are estimates and are subject to change. No adjustments have been made to reflect the anticipated benefits of expected cost savings or revenue synergies, nor expenses required to achieve those savings and synergies.

All dollar amounts presented within these Notes to Unaudited Pro Forma Condensed Combined Financial Statements are in thousands, except per share data. Share amounts are in thousands.

Note 2 — Preliminary purchase price allocation

Under the terms of the merger agreement, holders of Professional common stock have the right to receive a fixed exchange ratio of 0.8909 shares of Seacoast common stock for each share of Professional common stock. For purposes of the unaudited pro forma condensed combined balance sheet, the estimated merger consideration is based on the total number of shares issued and outstanding as of June 30, 2022, restricted stock awards (“RSAs”) that will be issued to Professional employees prior to the close of the transaction, shares issued to replace stock appreciation rights (“SARs”) prior to the close of the acquisition and the closing price per share of Seacoast common stock of $30.23 on September 30, 2022. The preliminary

31

purchase price also takes into consideration the estimated fair value attributable to Professional’s outstanding options as of June 30, 2022 that will convert to Seacoast options on the acquisition date.

Refer to the table below for the preliminary calculation of estimated merger consideration:

Preliminary calculation of estimated merger consideration (In thousands, except per share data)	​
Expected Professional shares at closing	​	14,360
Per share exchange ratio	​	0.8909
Number of shares of Seacoast common stock issued	​	12,793
Multiplied by Seacoast common stock price per share on September 30, 2022	$	30.23
Value of Seacoast common stock issued	​	386,730
Fair value of Professional options converted	​	11,402
Estimated total merger consideration	$	398,132

The estimated merger consideration as shown in the table above is allocated to the tangible and intangible assets acquired and liabilities assumed of Professional based on their estimated fair values. As mentioned above in Note 1, Seacoast has not completed the valuation analysis and calculations in sufficient detail necessary to arrive at the required estimates of the fair market value of the Professional assets to be acquired or liabilities assumed, other than a preliminary estimate for intangible assets and certain financial assets and financial liabilities. Accordingly, apart from the aforementioned, certain assets acquired and liabilities assumed are presented at their respective carrying amounts and should be treated as preliminary values. The fair value assessments are preliminary and are based upon available information and certain assumptions, which Seacoast believes are reasonable under the circumstances. Actual results may differ materially from the assumptions within the unaudited pro forma condensed combined financial statements.

The following table sets forth a preliminary allocation of the estimated merger consideration to the fair value of the identifiable tangible and intangible assets acquired and liabilities assumed of Professional using Professional’s unaudited consolidated balance sheet as of June 30, 2022:

Allocation of purchase price (In thousands)	June 30, 2022
Estimated total merger consideration	​	$	398,132
Assets:	​	​	​
Cash	​	​	368,079
Securities	​	​	192,004
Loans	​	​	1,892,933
Bank premises and equipment	​	​	8,570
Core deposit intangibles	​	​	43,500
Other assets	​	​	108,304
Total assets	​	​	2,613,390
Liabilities:	​	​	​
Deposits	​	​	2,380,535
Other borrowings	​	​	21,636
Other liabilities	​	​	21,745
Total liabilities	​	​	2,423,916
Net assets acquired	​	​	189,474
Estimated pro forma goodwill	​	$	208,658

Note 3 — Pro Forma Adjustments

1.

Adjustments to record held to maturity investment securities at fair value.

2.

Elimination of Professional’s existing net fair value adjustments on previously acquired loans, and recognition of an estimated $63.7 million in net fair value adjustments expected to be recorded on loans in the merger.

3.

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.

INFORMATION ABOUT THE PROFESSIONAL SPECIAL MEETING

This section contains information about the special meeting that Professional has called to allow Professional shareholders to vote on the approval of the merger agreement and the adjournment proposal. The Professional board of directors is mailing this proxy statement/prospectus to you, as a Professional shareholder, on or about                  , 2022. Together with this proxy statement/prospectus, the Professional board of directors is also sending you a notice of the special meeting of Professional shareholders and a form of proxy that the Professional board of directors is soliciting for use at the special meeting and at any adjournments or postponements of the special meeting.

Time, Date, and Place

[The special meeting is scheduled to be held on                  , 2022 at        A.M., local time, at the                   located at                  , Miami, Florida                  .]

36

Matters to be Considered at the Meeting

At the special meeting, Professional shareholders will be asked to consider and vote on:

•

a proposal to approve the merger agreement, which we refer to as the merger proposal;

•

a proposal of the Professional board of directors to adjourn or postpone the special meeting, if necessary or appropriate, including to permit further solicitation of proxies if there are insufficient votes at the time of the special meeting to approve the merger agreement, which we refer to as the adjournment proposal; and

•

any other matters as may properly be brought before the special meeting or any adjournment or postponement of the special meeting.

At this time, the Professional board of directors is unaware of any other matters that may be presented for action at the special meeting. If any other matters are properly presented, however, and you have completed, signed and submitted your proxy, the person(s) named as proxy will have the authority to vote your shares in accordance with his or her judgment with respect to such matters. A copy of the merger agreement is included in this proxy statement/prospectus as Appendix A, and we encourage you to read it carefully in its entirety.

Recommendation of the Professional Board of Directors

The Professional board of directors recommends that Professional shareholders vote “FOR” the merger proposal and “FOR” the adjournment proposal. See “The Merger - Professional’s Reasons for the Merger and Recommendations of the Professional Board of Directors.”

Record Date and Quorum

[                 , 2022] has been fixed as the record date for the determination of Professional shareholders entitled to notice of, and to vote at, the special meeting and any adjournment or postponement thereof. At the close of business on the record date, there were [                  ] shares of Professional Class A common stock outstanding and entitled to vote at the special meeting, held by approximately           holders of record.

A quorum is necessary to transact business at the special meeting. The presence, in person or by proxy, of the holders of a majority of the outstanding shares of Professional Class A common stock is necessary to constitute a quorum. Shares of Professional Class A common stock represented at the special 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 Professional Class A common stock is represented at the special meeting, it will be counted for the purpose of determining a quorum not only at the special meeting but also at any adjournment or postponement of the special meeting. In the event that a quorum is not present at the special meeting, it is expected that the special meeting will be adjourned or postponed.

Required Vote

The affirmative vote of a majority of the outstanding shares of Professional Class A 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 adjournment proposal will be approved if the votes of Professional Class A 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 Professional Class A common stock you own as of the record date for the special meeting entitles you to one vote at the special meeting on all matters properly presented at the meeting.

37

Voting of Proxies; Incomplete Proxies

If you hold your shares of Professional Class A common stock in your own name, you are a shareholder of record and you may vote using one of the following methods:

•

By telephone: by calling the toll-free number indicated on your proxy card and following the recorded instructions.

•

Through the Internet: by visiting the website indicated on your proxy card and following the instructions.

•

Complete and return the proxy card in the enclosed envelope. The envelope requires no additional postage if mailed in the United States.

Professional requests that shareholders vote by telephone, over the Internet or by completing and signing the accompanying proxy card and returning it to Professional as soon as possible in the enclosed postage-paid envelope. When a properly executed proxy is returned, the shares of Professional Class A common stock represented by it will be voted at the special meeting in accordance with the instructions contained on the proxy. If any proxy is returned without indication as to how to vote, the shares of Professional Class A common stock represented by the proxy will be voted “FOR” the merger proposal and “FOR” the adjournment proposal.

If your shares are held in “street name” by a bank or broker, you should check the voting form used by your bank or broker to determine whether it may vote by telephone or the Internet.

Every vote is important.   Accordingly, you should sign, date and return the enclosed proxy card, or vote via the Internet or by telephone, whether or not you plan to attend the special meeting in person. Sending in your proxy card or voting by telephone or on the Internet will not prevent you from voting your shares personally at the meeting, since you may revoke your proxy at any time before it is voted.

As of the date hereof, the Professional board of directors has no knowledge of any business that will be presented for consideration at the special meeting and that would be required to be set forth in this proxy statement/prospectus or the related proxy card other than the matters set forth in Professional’s Notice of Special Meeting of Shareholders. If any other matter is properly presented for consideration at the special meeting, the persons named in the enclosed form of proxy and acting thereunder will vote in accordance with their discretion on such matter.

Voting Shares Held in “Street Name”

If your shares are held in “street name” through a bank, broker, or other nominee, you must provide the record holder of your shares with instructions on how to vote the shares. Please follow the voting instructions provided by the bank or broker. You may not vote shares held in street name by returning a proxy card directly to Professional or by voting in person at the special meeting unless you obtain a “legal proxy” from your bank, broker, or other nominee. Furthermore, banks or brokers who hold shares of Professional Class A common stock on behalf of their customers will not vote your shares of Professional Class A common stock or give a proxy to Professional to vote those shares with respect to any proposal without specific instructions from you, as banks or brokers do not have discretionary voting power on any proposal to be presented at the special meeting.

Revocation of Proxies

You can revoke your proxy at any time before your shares are voted. If you are a shareholder of record, then you can revoke your proxy by:

•

timely delivering a new, valid proxy bearing a later date;

•

attending the special meeting and voting your shares in person; or

•

delivering prior to the special meeting a written notice of revocation to Professional’s Secretary at the following address: Professional Holding Corp., 396 Alhambra Circle, Suite 255, Coral Gables, Florida 33134.

38

If you choose to send a completed proxy bearing a later date or a notice of revocation, the new proxy or notice of revocation must be received before the beginning of the special meeting. Attendance at the special meeting will not, in and of itself, constitute revocation of a proxy. If you hold your shares in street name with a bank, broker or other nominee, you must follow the directions you receive from your bank, broker or other nominee to change your vote. Your last vote will be the vote that is counted.

Shares Subject to Support Agreement; Shares Held by Directors and Executive Officers

As of the record date, directors and executive officers of Professional and Professional Bank owned and were entitled to vote [                 ] shares of Professional Class A common stocks, representing approximately [           ]% of the outstanding shares of Professional Class A common stock entitled to vote on that date.

A total of [                 ] shares of Professional Class A common stock, representing approximately [           ]% of the outstanding shares of Professional Class A common stock entitled to vote at the special meeting, are subject to voting agreements between Seacoast and certain directors or other affiliates of Professional and/or Professional Bank who held shares of Professional Class A common stock as of the date of the merger agreement. Pursuant to the voting agreement, these directors and other affiliates have agreed to, at any meeting of Professional shareholders, however called, or any adjournment or postponement thereof (and subject to certain exceptions):

•

vote (or cause to be voted) all shares of Professional’s common stock beneficially owned by such director or other affiliate, as applicable, and which such director or other affiliate has the right to vote in favor of the approval of the merger agreement, the merger and each of the transactions contemplated by the merger agreement;

•

not vote or grant any proxies to any third party, except where such proxies are directed to vote in favor of the merger agreement, the merger and the transactions contemplated by the merger agreement; and

•

vote (or cause to be voted) his or her shares against any competing transaction.

Pursuant to the voting agreement, without the prior written consent of Seacoast, each party to a voting agreement has further agreed not to sell or otherwise transfer any shares of Professional Class A common stock. The foregoing summary of the voting agreements does not purport to be complete, and is qualified in its entirety by reference to the form of voting agreement attached as Exhibit B to the merger agreement, which is attached as Appendix A to this document.

For more information about the beneficial ownership of Professional Class A common stock by each director and executive officer, directors and executive officers as a group, and holders of 5% or more of the outstanding shares of Professional Class A common stock see “Beneficial Ownership of Professional Common Stock by Management and Principal Shareholders of Professional.”

Solicitation of Proxies

The proxy for the special meeting is being solicited on behalf of the Professional board of directors. Professional will bear the entire cost of soliciting proxies from you. Professional will reimburse brokerage firms and other custodians, nominees and fiduciaries for reasonable expenses incurred by them in sending proxy materials to the beneficial owners of Professional stock. Proxies will be solicited principally by mail, but may also be solicited by the directors, officers, and other employees of Professional in person or by telephone, facsimile or other means of electronic communication. Directors, officers and employees will receive no compensation for these activities in addition to their regular compensation but may be reimbursed for out-of-pocket expenses in connection with such solicitation. Professional has engaged Georgeson LLC to distribute and solicit proxies and will pay that firm a fee of $15,000, plus reasonable expenses, for these services.

Attending the Meeting

All holders of Professional Class A common stock, including shareholders of record and shareholders who hold their shares in street name through banks, brokers or other nominees, are cordially invited to attend

39

the special meeting. Shareholders of record can vote in person at the special meeting. If you are not a shareholder of record and would like to vote in person at the special meeting, you must produce a legal proxy executed in your favor by the record holder of your shares. In addition, you must bring a form of personal photo identification with you in order to be admitted at the special meeting. We reserve the right to refuse admittance to anyone without proper proof of share ownership or without proper photo identification.

PROPOSAL 1: THE MERGER

Background of the Merger

As part of its ongoing consideration and evaluation of long-term strategies and prospects, the Professional board of directors and senior management have periodically assessed strategic alternatives for maximizing shareholder value, including growth opportunities and operational efficiencies. The strategic discussions have focused on, among other things, the business environment facing financial institutions generally and Professional, in particular, as well as conditions and ongoing consolidation in the financial services industry. In contemplating its strategic objectives, the Professional board of directors has considered potential merger opportunities to maximize shareholder value while at the same time continuing to provide quality products and services to its communities and customers.

In late February 2022, Chuck Shaffer, Chairman and Chief Executive Officer of Seacoast, reached out to Herbert Martens, Chairman of the Board of Professional, to establish a relationship and understand the forward direction for Professional Bank. At that time, Mr. Martens advised that Professional had no desire to sell to another party and was committed to remaining independent. On March 17, 2022, Mr. Martens and Mr. Shaffer met and discussed a variety of topics, including the forward direction for Professional. During that discussion, Mr. Martens again emphasized that the current intention of the Professional board of directors was that Professional would remain independent.

The parties had no further contact until April 12, 2022, when Mr. Martens advised Mr. Shaffer that on April 11, 2022, Professional had received an unsolicited non-binding letter of intent from a third party seeking to purchase Professional. Prior to the receipt of the letter of intent, neither the Professional board of directors nor its management had intended to solicit a sale or merger of Professional. Mr. Martens and Mr. Shaffer informally discussed Seacoast’s interest in a potential merger/acquisition transaction with Professional. At approximately the same time, Professional’s investment bankers, Stephens, informally contacted Piper Sandler, investment bankers to Seacoast, to discuss a potential transaction. On April 13, 2022, Seacoast formally engaged Piper Sandler to act as its exclusive financial advisor in connection with a possible transaction. Following further discussions, on April 15, 2022, Professional and Seacoast entered into a confidentiality agreement in connection with a possible transaction.

During the period following receipt of the unsolicited offer, Mr. Martens conducted informal discussions with various members of the Professional board of directors to apprise them of the offer and to discuss possible responses.

On April 16, 2022, certain members of the Professional board of directors met with representatives of Stephens to discuss the unsolicited offer from the third party. On April 21, 2022, the Professional board of directors appointed those members to a special committee to evaluate the unsolicited offer, and on April 22, 2022 the Professional board of directors approved the engagement of Stephens to act as its exclusive financial advisor in connection with a possible transaction. On April 27, 2022, Mr. Martens and Mr. Shaffer met to discuss talent and retention, the integration process, and other matters; they did not discuss deal pricing or deal structure, but rather focused on the Professional team and how to bring the two companies together.

Following its engagement, Stephens contacted 11 potential parties, including Seacoast and the initial third-party offeror, with regard to a possible combination with Professional. Three of those parties entered into confidentiality agreements with Professional, following which they were given access to a virtual data room. The parties were further advised that the deadline for the submission of a bid was June 1, 2022. Three potential buyers submitted proposals to purchase Professional, including Seacoast.

On June 1, 2022, Mr. Shaffer delivered a letter of intent to the Professional board of directors, offering a fixed exchange ratio of 0.8668 shares of Seacoast common stock for each outstanding share of Professional common stock. In the following days, Mr. Shaffer discussed Seacoast’s proposed offer with Abel Iglesias, President and Chief Executive Officer of Professional and Mr. Martens. On June 3, 2022, Stephens reviewed the three letters of intent that had been submitted concerning the acquisition of Professional. On June 10, 2022, Stephens presented to the Professional board of directors its analysis of each of the three proposals received regarding the purchase of Professional. Following this presentation and related discussions, a

41

revised draft letter of intent (which included a revised fixed exchange ratio of 0.8909) was signed on June 10, 2022, 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 August 15, 2022 or the date on which the parties agreed to discontinue discussions.

During June and July 2022, Seacoast conducted a formal due diligence review of Professional, which included credit review and management meetings, and the parties began to discuss and negotiate the terms of a definitive agreement. Also, during this time frame, Seacoast and its outside legal counsel reviewed and analyzed diligence materials that were posted by Professional and its representative to the virtual data room.

On July 21, 2022, Stephens, together with members of Professional’s management and counsel, conducted a reverse due diligence review of Seacoast.

From late June 2022 through early August 2022, legal counsel for Professional and legal counsel for Seacoast, along with management and investment banking advisors of both companies, prepared, exchanged several drafts of, and negotiated the terms of, the merger agreement and related ancillary documents and agreements (including disclosure schedules, voting agreements for directors, noncompetition agreements for directors and officers, and employment agreements with certain executive officers of Professional).

On July 27, 2022, the special committee of the Professional board of directors met to consider the proposed transaction with Seacoast and, subject to the negotiation and completion of a definitive merger agreement and related documents, and to the delivery of the opinion of Stephens described below, determined to recommend that the Professional board of directors approve the merger agreement.

On August 5, 2022, the Professional board of directors held a special meeting, in which representatives of Stephens and the Gunster law firm, counsel to Professional, participated. During the meeting, the directors reviewed with their advisors the terms of the merger agreement, and other relevant information; a Stephens representative reviewed Stephens’s financial analysis summarized below under “The Merger — Opinion of Professional’s Financial Advisor” and delivered the written opinion of Stephens, which is attached to this proxy statement/prospectus as Appendix C. Stephens’s written opinion states 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 Professional in the merger pursuant to the merger agreement is fair from a financial point of view. In addition, counsel reviewed with the directors of Professional the most recent draft of the proposed merger agreement and related transaction documents, and the legal standards applicable to the Professional 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 Professional Board of Directors and Reasons for the Merger” below, the Professional board of directors concluded that the merger was fair to and in the best interest of Professional and its shareholders and unanimously approved and adopted the merger agreement and the transactions contemplated thereby and recommended that Professional’s shareholders approve the merger agreement.

On August 5, 2022, 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 reviewed with the Seacoast board of directors the principal terms of the proposed transaction and the financial impacts of the merger on Seacoast and provided comparable transaction analysis for other Florida and national bank mergers. In addition, a Piper Sandler representative reviewed with the Seacoast board its financial analysis summarized below under “The Merger — Opinion of Seacoast’s Financial Advisor” and delivered to the Seacoast board Piper Sandler’s opinion, which is attached to this proxy statement/prospectus as Appendix B, to the effect that, based upon and subject to the various qualifications and considerations set forth in such opinion, the merger consideration was fair, from a financial point of view, to Seacoast. Also at the meeting, representatives of Alston & Bird, counsel to Seacoast, reviewed with 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 and the

42

transactions and agreements contemplated by it and determined that the merger agreement and the transactions contemplated by it were in the best interests of Seacoast and its shareholders.

On August 7, 2022, the parties signed the merger agreement and the related agreements. A press release announcing the transaction was issued the next morning and a conference call with analysts and investors to discuss the merger was held the morning of August 8, 2022.

At a meeting held on August 5, 2022, following consideration at several meetings and other discussions among its members, including the members of the special committee, the Professional board of directors determined that the merger agreement is advisable, fair to and in the best interests of Professional and its shareholders. Accordingly, Professional’s board of directors approved and adopted the merger agreement and the merger and the other transactions contemplated by the merger agreement and recommends that Professional shareholders vote “FOR” the approval of the merger agreement.

In determining to approve and adopt the merger agreement and the merger and the other transactions contemplated by the merger agreement, and to recommend that its shareholders approve the merger agreement, the Professional board, in consultation with Professional’s management, as well as its financial and legal advisors, considered a number of factors, including the following material factors:

•

the business, operations, financial condition, asset quality, earnings and prospects of Professional and Seacoast, both individually and on a combined basis, including that Seacoast’s business and operations complement those of Professional and that the merger would result in a combined company with diversified revenue sources, a well-balanced loan portfolio and an attractive funding base, as evidenced by a significant portion of core deposit funding;

•

its understanding of the current and prospective environment in which Professional and Seacoast operate, including local, regional, and national economic conditions, the interest rate environment, regulatory initiatives and compliance mandates and their potential impact on operating costs, the competitive environment for financial institutions generally, and the likely effect of these factors on Professional both with and without the proposed transaction;

•

the reduction in the number of financial institutions with an interest in acquiring Florida banks due to continued consolidation in the banking industry and the acquisition by other financial institutions of several of the banks that were historically active in acquiring Florida banks;

•

the fact that the fixed exchange ratio provided for in the merger agreement will result in an increase in the merger consideration to be received by Professional shareholders in the merger to the extent that the market price of Seacoast common stock is higher at the time of the closing of the merger;

•

the results that Professional could expect to achieve operating independently, and the likely risks and benefits to Professional shareholders of that course of action, as compared to the value of the merger consideration to be received from Seacoast;

•

its view that a merger with a larger bank holding company could provide economies of scale, increase efficiencies of operations and enhance customer products and services;

•

its view of the strategic alternatives available to Professional for enhancing value over the long term, the potential risks, rewards and uncertainties associated with those alternatives, and an acquisition by Seacoast compared to those alternatives;

•

the complementary nature of the cultures of the two companies, which management believes should facilitate integration and implementation of the transaction;

•

its belief, and that of management, that the combined company will have a strong capital position;

•

its belief that the transaction is likely to provide substantial value to Professional’s shareholders;

•

the financial analyses by Stephens, Professional’s financial advisor, and the opinion delivered by Stephens to Professional’s board on August 5, 2022, to the effect that, as of the date of such opinion, and subject to the procedures followed, assumptions made, matters considered, and qualifications

43

and limitations on the review undertaken by Stephens as set forth in its opinion, the merger consideration to be received by the shareholders of Professional in the merger pursuant to the merger agreement is fair from a financial point of view to the shareholders of Professional, as more fully described in the section entitled “The Merger — Opinion of Professional’s Financial Advisor”;

•

the financial and other terms of the merger agreement, the expected tax treatment and deal protection provisions, including the ability of Professional’s board of directors, under certain circumstances, to withdraw or materially adversely modify its recommendation to Professional shareholders that they approve the merger agreement (subject to payment of a termination fee), each of which it reviewed with its outside financial and legal advisors;

•

the fact that the merger consideration will consist of shares of Seacoast common stock, which would allow Professional shareholders to participate in a significant portion of the future performance of the combined Professional and Seacoast business and synergies resulting from the merger, and the value to Professional shareholders represented by that consideration;

•

the proforma ownership by Professional shareholders in Seacoast following the closing of the merger;

•

the fact that Professional’s directors and executive officers have financial interests in the merger in addition to their interests as Professional shareholders, including financial interests that are the result of compensation arrangements with Professional, and the manner in which such interests would be affected by the merger;

•

the regulatory and other approvals required in connection with the merger and the expectation that such regulatory approvals will be received in a timely manner and without the imposition of unacceptable conditions;

•

the fact that the merger consideration will generally be tax-free to Professional shareholders based on the expected tax treatment of the merger as a “reorganization” for U.S. federal income tax purposes, as further described under “The Merger — U.S. Federal Income Tax Consequences of the Merger”;

•

the greater liquidity in the trading market for Seacoast common stock relative to the market for Professional common stock due to Seacoast’s greater market capitalization and the historically greater trading volumes in its comment stock; and

•

the opportunity for Professional shareholders to receive Seacoast common stock which has historically paid a cash dividend, and the fact that no cash dividends have been paid on Professional shares since its organization.

The Professional board of directors also considered a number of potential risks and uncertainties associated with the merger in connection with its deliberation of the proposed transaction, including, without limitation, 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;

•

the potential risk of diverting management attention and resources from the operation of Professional’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;

•

the requirement that Professional conduct its business in the ordinary course and the other restrictions on the conduct of Professional’s business prior to the completion of the merger, which may delay or prevent Professional from undertaking business opportunities that may arise pending completion of the merger;

•

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

•

the potential risks associated with achieving anticipated cost synergies and savings and successfully integrating Professional’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;

44

•

the possibility that Professional will have to pay a termination fee of approximately $21.79 million to Seacoast if the merger agreement is terminated under certain circumstances;

•

that, subject to limited exceptions, the exchange ratio is fixed, so that if the market price of Seacoast common stock is lower at the time of the closing of the merger, the economic value of the merger consideration to be received by Professional shareholders in exchange for their shares of common stock will also be lower; and

•

the other risks under the sections entitled “Cautionary Statement About Forward-Looking Statements” and “Risk Factors.”

In considering the recommendation of the Professional board of directors, shareholders should be aware that certain directors and officers of Professional may have interests in the merger that are different from, or in addition to, interests of Professional shareholders generally and may create potential conflicts of interest. The Professional board was aware of these interests and considered them when evaluating and negotiating the merger agreement, the merger and the other transactions contemplated by the merger agreement, and in recommending to Professional’s shareholders that they vote in favor of the proposal to approve the merger agreement. See “Interests of Professional Executive Officers and Directors in the Merger.”

The foregoing discussion is not intended to be exhaustive; rather, it includes the material factors considered by the Professional board. In reaching its decision to adopt and approve the merger agreement and the merger and the other transactions contemplated by the merger agreement, the Professional board did not quantify or assign any relative weights to the factors considered, and individual directors may have given different weights to different factors. The Professional board considered all these factors as a whole, including discussions with, and questioning of, Professional’s management and Professional’s financial and legal advisors, and overall considered the factors to be favorable to, and to support, its determination.

For the reasons set forth above, the Professional board of directors has adopted and approved the merger agreement and the transactions contemplated thereby and recommends that you vote “FOR” the merger proposal and “FOR” the adjournment proposal.

Each of the directors of Professional has entered into a voting agreement with Seacoast, pursuant to which each has agreed to vote in favor of the merger proposal and the other proposal to be voted on at the Professional special meeting, subject to the terms of the voting agreement. The voting agreements are discussed in more detail in the section entitled “Information About the Professional Special Meeting — Shares Subject to Voting Agreements; Shares Held by Directors and Executive Officers.”

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 Professional 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 Professional, the market condition of the market area in which Professional 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 footprint in the dynamic tri-county South Florida market, which includes Miami-Dade, Broward, and Palm Beach counties, the largest MSA in Florida and the eighth largest in the nation, provide opportunities for future growth and provide the potential to realize operational efficiencies. Seacoast’s board of directors also considered the financial condition and valuations of both Professional and Seacoast as well as the financial and other effects the merger would have on Seacoast’s shareholders. In addition, the board of directors also considered the analysis and presentations from its outside financial advisor, Sandler, as well as Sandler’s fairness opinion delivered to the Seacoast board of directors.

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

45

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

Opinion of Seacoast’s Financial Advisor

Opinion of Seacoast Banking Corporation of Florida’s (“Seacoast”) Financial Advisor

Seacoast retained Piper Sandler to act as financial advisor to Seacoast’s board of directors and its subsidiaries in connection with Seacoast’s consideration of a possible business combination with Professional. Seacoast selected Piper Sandler to act as its financial advisor because Piper Sandler is a nationally recognized investment banking firm whose principal business specialty is financial institutions. In the ordinary course of its investment banking business, Piper Sandler is regularly engaged in the valuation of financial institutions and their securities in connection with mergers and acquisitions and other corporate transactions.

Piper Sandler acted as financial advisor to Seacoast’s board of directors and its subsidiaries in connection with the proposed merger and participated in certain of the negotiations leading to the execution of the merger agreement. At the August 5, 2022 meeting at which Seacoast’s board of directors considered the merger and the merger agreement, Piper Sandler delivered to the board of directors its oral opinion, which was subsequently confirmed in writing on August 5, 2022, to the effect that, as of such date, the merger consideration was fair to Seacoast from a financial point of view. The full text of Piper Sandler’s opinion is attached as Appendix B to this proxy statement/prospectus. The opinion outlines the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by Piper Sandler in rendering its opinion. The description of the opinion set forth below is qualified in its entirety by reference to the full text of the opinion. Holders of Seacoast common stock are urged to read the entire opinion carefully in connection with their consideration of the proposed merger.

Piper Sandler’s opinion was directed to the board of directors of Seacoast in connection with its consideration of the merger and the merger agreement and does not constitute a recommendation to any shareholder of Seacoast as to how any such shareholder should vote at any meeting of shareholders called to consider and vote upon the approval of the merger and the merger agreement. Piper Sandler’s opinion was directed only to the fairness, from a financial point of view, of the merger consideration to Seacoast and did not address the underlying business decision of Seacoast to engage in the merger, the form or structure of the merger or any other transactions contemplated in the merger agreement, the relative merits of the merger as compared to any other alternative transactions or business strategies that might exist for Seacoast, or the effect of any other transaction in which Seacoast might engage. Piper Sandler also did not express any opinion as to the fairness of the amount or nature of the compensation to be received in the merger by any officer, director or employee of Seacoast or Professional, or any class of such persons, if any, relative to the compensation to be received in the merger by any other shareholder. Piper Sandler’s opinion was approved by Piper Sandler’s fairness opinion committee.

In connection with its opinion, Piper Sandler reviewed and considered, among other things:

•

a draft of the Agreement and Plan of Merger, dated August 5, 2022;

•

certain publicly available financial statements and other historical financial information of Seacoast and SNB that Piper Sandler deemed relevant;

•

certain publicly available financial statements and other historical financial information of Professional and Professional Bank that Piper Sandler deemed relevant;

•

publicly available mean analyst balance sheet and earnings per share estimates for Seacoast for the years ending December 31, 2022 and December 31, 2023 with a long-term annual net income and balance sheet growth rate for the years ending December 31, 2024 through December 31, 2026, as provided by the senior management of Seacoast;

46

•

certain financial projection assumptions for Professional for the years ending December 31, 2022 through December 31, 2026, as provided by the senior management of Seacoast;

•

the pro forma financial impact of the merger on Seacoast based on certain assumptions relating to transaction expenses, purchase accounting adjustments and cost savings, as well as certain adjustments for current expected credit losses (CECL) accounting standards, as well as certain assumptions relating to the sale and reinvestment of Professional’s securities portfolio and the investment of Professional cash and equivalents at closing of the merger, as provided by the senior management of Seacoast;

•

the publicly reported historical price and trading activity for Seacoast common stock and Professional common stock, including a comparison of certain stock trading information for Seacoast common stock and Professional common stock and certain stock indices, as well as similar publicly available information for certain other companies, the securities of which are publicly traded;

•

a comparison of certain financial and market information for Seacoast and Professional with similar financial institutions for which information was publicly available;

•

the financial terms of certain recent business combinations in the bank and thrift industry (on a regional basis), to the extent publicly available;

•

the current market environment generally and the banking environment in particular; and

•

such other information, financial studies, analyses and investigations and financial, economic and market criteria as Piper Sandler considered relevant.

Piper Sandler also discussed with certain members of the senior management of Seacoast and its representatives the business, financial condition, results of operations and prospects of Seacoast and held similar discussions with certain members of the management of Professional and its representatives regarding the business, financial condition, results of operations and prospects of Professional.

In performing its review, Piper Sandler relied upon the accuracy and completeness of all of the financial and other information that was available to Piper Sandler from public sources, that was provided to Piper Sandler by Seacoast or Professional or their respective representatives, or that was otherwise reviewed by Piper Sandler, and Piper Sandler assumed such accuracy and completeness for purposes of rendering its opinion without any independent verification or investigation. Piper Sandler further relied on the assurances of the respective managements of Seacoast and Professional that they were not aware of any facts or circumstances that would have made any of such information inaccurate or misleading. Piper Sandler was not asked to and did not undertake an independent verification of any of such information and Piper Sandler did not assume any responsibility or liability for the accuracy or completeness thereof. Piper Sandler did not make an independent evaluation or perform an appraisal of the specific assets, the collateral securing assets or the liabilities (contingent or otherwise) of Seacoast or Professional, nor was Piper Sandler furnished with any such evaluations or appraisals. Piper Sandler rendered no opinion or evaluation on the collectability of any assets or the future performance of any loans of Seacoast or Professional. Piper Sandler did not make an independent evaluation of the adequacy of the allowance for loan losses of Seacoast or Professional, or of the combined entity after the merger, and Piper Sandler did not review any individual credit files relating to Seacoast or Professional. Piper Sandler assumed, with Seacoast’s consent, that the respective allowances for loan losses for both Seacoast and Professional were adequate to cover such losses and would be adequate on a pro forma basis for the combined entity.

In preparing its analyses, Piper Sandler used publicly available mean analyst balance sheet and earnings per share estimates for Seacoast for the years ending December 31, 2022 and December 31, 2023 with a long-term annual net income and balance sheet growth rate for the years ending December 31, 2024 through December 31, 2026, as provided by the senior management of Seacoast. In addition, Piper Sandler used certain financial projection assumptions for Professional for the years ending December 31, 2022 through December 31, 2026, as provided by the senior management of Seacoast. Piper Sandler also received and used in its pro forma analyses certain assumptions relating to transaction expenses, purchase accounting adjustments and cost savings, as well as certain adjustments for CECL accounting standards, as well as certain assumptions relating to the sale and reinvestment of Professional’s securities portfolio and the investment of Professional cash and equivalents at closing of the merger, as provided by the senior

47

management of Seacoast. With respect to the foregoing information, the senior management of Seacoast confirmed to Piper Sandler that such information reflected (or, in the case of the publicly available analyst estimates referred to above, were consistent with) the best currently available estimates and judgments of senior management as to the future financial performance of Seacoast and Professional, respectively, and Piper Sandler assumed that the financial results reflected in such information would be achieved. Piper Sandler expressed no opinion as to such estimates or judgments, or the assumptions on which such information was based. Piper Sandler also assumed that there had been no material change in the respective assets, financial condition, results of operations, business or prospects of Seacoast or Professional since the date of the most recent financial statements made available to Piper Sandler. Piper Sandler assumed in all respects material to its analyses that Seacoast and Professional would remain as going concerns for all periods relevant to its analyses.

Piper Sandler also assumed, at Seacoast’s direction and with Seacoast’s consent, that (i) each of the parties to the merger agreement would comply in all material respects with all material terms and conditions of the merger agreement and all related agreements, that all of the representations and warranties contained in such agreements were true and correct in all material respects, that each of the parties to such agreements would perform in all material respects all of the covenants and other obligations required to be performed by such party under such agreements and that the conditions precedent in such agreements were not and would not be waived, (ii) in the course of obtaining the necessary regulatory or third party approvals, consents and releases with respect to the merger, no delay, limitation, restriction or condition would be imposed that would have an adverse effect that would be material to the analyses of the merger, or any related transactions, and (iii) the merger and any related transactions would be consummated in accordance with the terms of the merger agreement without any waiver, modification or amendment of any material term, condition or agreement thereof and in compliance with all applicable laws and other requirements. Piper Sandler expressed no opinion as to any legal, accounting or tax matters relating to the merger and the other transactions contemplated by the merger agreement.

Piper Sandler’s opinion was necessarily based on financial, regulatory, economic, market and other conditions as in effect on, and the information made available to Piper Sandler as of, the date thereof. Events occurring after the date thereof could materially affect Piper Sandler’s opinion. Piper Sandler has not undertaken to update, revise, reaffirm or withdraw its opinion or otherwise comment upon events occurring after the date thereof. Piper Sandler expressed no opinion as to the trading value of Seacoast common stock or Professional common stock at any time or what the value of Seacoast common stock will be once it is actually received by the holders of Professional common stock.

In rendering its opinion, Piper Sandler performed a variety of financial analyses. The summary below is not a complete description of all the analyses underlying Piper Sandler’s opinion or the presentation made by Piper Sandler to Seacoast’s board of directors, but is a summary of the material analyses performed and presented by Piper Sandler. The summary includes information presented in tabular format. In order to fully understand the financial analyses, these tables must be read together with the accompanying text. The tables alone do not constitute a complete description of the financial analyses. The preparation of a fairness opinion is a complex process involving subjective judgments as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances. The process, therefore, is not necessarily susceptible to a partial analysis or summary description. Piper Sandler believes that its analyses must be considered as a whole and that selecting portions of the factors and analyses to be considered without considering all factors and analyses, or attempting to ascribe relative weights to some or all such factors and analyses, could create an incomplete view of the evaluation process underlying its opinion. Also, no company included in Piper Sandler’s comparative analyses described below is identical to Seacoast or Professional and no transaction is identical to the merger. Accordingly, an analysis of comparable companies or transactions involves complex considerations and judgments concerning differences in financial and operating characteristics of the companies and other factors that could affect the public trading values or transaction values, as the case may be, of Seacoast and Professional and the companies to which they were compared. In arriving at its opinion, Piper Sandler did not attribute any particular weight to any analysis or factor that it considered. Rather, Piper Sandler made qualitative judgments as to the significance and relevance of each analysis and factor. Piper Sandler did not form an opinion as to whether any individual analysis or factor (positive or negative) considered in isolation supported or failed to support its opinion, rather, Piper Sandler made its determination as to the fairness of the

48

merger consideration to Seacoast on the basis of its experience and professional judgment after considering the results of all its analyses taken as a whole.

In performing its analyses, Piper Sandler also made numerous assumptions with respect to industry performance, business and economic conditions and various other matters, many of which cannot be predicted and are beyond the control of Seacoast, Professional, and Piper Sandler. The analyses performed by Piper Sandler are not necessarily indicative of actual values or future results, both of which may be significantly more or less favorable than suggested by such analyses. Piper Sandler prepared its analyses solely for purposes of rendering its opinion and provided such analyses to Seacoast’s board of directors at its August 5, 2022 meeting. Estimates on the values of companies do not purport to be appraisals or necessarily reflect the prices at which companies or their securities may actually be sold. Such estimates are inherently subject to uncertainty and actual values may be materially different. Accordingly, Piper Sandler’s analyses do not necessarily reflect the value of Seacoast common stock or Professional common stock or the prices at which Seacoast or Professional common stock may be sold at any time. The analyses of Piper Sandler and its opinion were among a number of factors taken into consideration by Seacoast’s board of directors in making its determination to approve the merger agreement and the analyses described below should not be viewed as determinative of the decision of Seacoast’s board of directors with respect to the fairness of the merger consideration.

Summary of Proposed Merger Consideration and Implied Transaction Metrics

Piper Sandler reviewed the financial terms of the proposed merger. Pursuant to the terms of the merger agreement, at the effective time of the merger each share of Professional common stock issued and outstanding immediately prior to the effective time of the transaction, except for certain shares as set forth in the merger agreement, shall be converted into the right to receive 0.8909 of a share of Seacoast common stock (the “Merger Consideration”), subject to adjustment, as set forth in the merger agreement. Piper Sandler calculated an aggregate implied transaction value of approximately $484.4 million and an implied purchase price per share of $32.47 based on 13,954,314 shares of Professional common stock outstanding (including 211,933 restricted stock awards to be issued before closing of the merger), 713,863 options outstanding with a weighted average per share strike price of $10.96, and 904,500 stock appreciation rights (or SARs) outstanding with a weighted average strike price of $14.87. Piper Sandler calculated the following implied transaction metrics:

Transaction Price Per Share / Professional Tangible Book Value Per Share	215%
Transaction Price Per Share / LTM Earnings Per Share	23.0x
Transaction Price Per Share / Estimated 2022 Earnings Per Share(1)	20.5x
Transaction Price Per Share / Estimated 2023 Earnings Per Share(1)	15.1x

Net Present Value Analyses.

Piper Sandler performed an analysis that estimated the net present value of a share of Seacoast common stock assuming Seacoast performed in accordance with publicly available mean analyst balance sheet and earnings per share estimates for Seacoast for the years ending December 31, 2022 and December 31, 2023 with a long-term annual net income and balance sheet growth rate for the years ending December 31, 2024 through December 31, 2026, as provided by the senior management of Seacoast. To approximate the terminal value of a share of Seacoast common stock at December 31, 2026, Piper Sandler applied price to 2026 earnings multiples ranging from 10.0x to 17.5x and multiples of 2026 tangible book value ranging from 150% to 225%. The terminal values were then discounted to present values using different discount rates ranging from 8.0% to 12.0%, which were chosen to reflect different assumptions regarding required rates of return of holders or prospective buyers of Seacoast common stock. As illustrated in the following tables,

53

the analysis indicated an imputed range of values per share of Seacoast common stock of $19.50 to $38.27 when applying multiples of earnings and $24.30 to $41.74 when applying multiples of tangible book value.

Piper Sandler also considered and discussed with Seacoast’s board of directors how this analysis would be affected by changes in the underlying assumptions, including variations with respect to earnings. To illustrate this impact, Piper Sandler performed a similar analysis assuming Seacoast’s earnings varied from 20% above estimates to 20% below estimates. This analysis resulted in the following range of per share values for Seacoast’s common stock, applying the price to 2026 earnings multiples range of 10.0x to 17.5x referred to above and a discount rate of 8.85%.

Piper Sandler noted that the net present value analysis is a widely used valuation methodology, but the results of such methodology are highly dependent upon the numerous assumptions that must be made, and the results thereof are not necessarily indicative of actual values or future results.

Pro Forma Transaction Analysis.

Piper Sandler analyzed certain potential pro forma effects of the merger on Seacoast assuming the transaction closes on December 31, 2022. Piper Sandler also utilized the following information and assumptions: (i) publicly available mean analyst balance sheet and earnings per share estimates for Seacoast for the years ending December 31, 2022 and December 31, 2023 with a long-term annual net income and balance sheet growth rate for the years ending December 31, 2024 through December 31, 2026, as provided by the senior management of Seacoast; (ii) certain financial projection assumptions for Professional for the years ending December 31, 2022 through December 31, 2026, as provided by the senior management of Seacoast; (iii) certain assumptions relating to transaction expenses, purchase accounting adjustments and cost savings, as well as certain adjustments for CECL accounting standards, as provided by the senior management of Seacoast; (iv) certain assumptions relating to the sale and reinvestment of Professional’s

56

securities portfolio and the investment of Professional cash and equivalents at closing of the merger, as provided by the senior management of Seacoast. The analysis indicated that the transaction could be accretive to Seacoast’s estimated earnings per share (excluding one-time transaction costs and expenses) in the years ending December 31, 2023 through December 31, 2026 and dilutive to Seacoast’s estimated tangible book value per share at closing of the merger.

In connection with this analysis, Piper Sandler considered and discussed with Seacoast’s board of directors how the analysis would be affected by changes in the underlying assumptions, including the impact of final purchase accounting adjustments determined at the closing of the transaction, and noted that the actual results achieved by the combined company may vary from projected results and the variations may be material.

Piper Sandler’s Relationship.

Piper Sandler is acting as Seacoast’s financial advisor in connection with the merger and will receive a fee for such services in an amount equal to approximately $3.40 million, which fee is contingent upon the closing of the merger. Piper Sandler also received a $500,000 fee from Seacoast upon rendering its opinion, which opinion fee will be credited in full towards the advisory fee which will become payable to Piper Sandler upon closing of the transaction. Seacoast has also agreed to indemnify Piper Sandler against certain claims and liabilities arising out of Piper Sandler’s engagement and to reimburse Piper Sandler for certain of its out-of-pocket expenses incurred in connection with Piper Sandler’s engagement.

In the two years preceding the date of Piper Sandler’s opinion, Piper Sandler provided certain other investment banking services to Seacoast. In summary, Piper Sandler (i) acted as financial advisor to Seacoast in connection with Seacoast’s acquisition of Legacy Bank of Florida, which transaction closed in August 2021 and for which Piper Sandler received an advisory fee of approximately $925,000, (ii) acted as financial advisor to Seacoast in connection with Seacoast’s acquisition of Sabal Palm Bancorp, Inc. and Business Bank of Florida, Corp., which transactions closed in January 2022 and for which Piper Sandler received an aggregate advisory fee of approximately $1 million, (iii) acted as financial advisor to Seacoast in connection with Seacoast’s acquisition of Apollo Bancshares, Inc., which transaction was announced in March 2022 and for which Piper Sandler anticipates receiving an aggregate advisory fee of approximately $1.85 million, which fee is contingent upon the closing of the transaction, and (iv) acted as financial advisor to Seacoast in connection with Seacoast’s acquisition of Drummond Banking Company, which transaction was announced in May 2022 and for which Piper Sandler anticipates receiving an aggregate advisory fee of approximately $2 million, which fee is contingent upon the closing of the transaction. In addition, affiliates of Piper Sandler, Piper Sandler Hedging Services, LLC (“Piper Sandler Hedging”) and Piper Sandler Loan Strategies, LLC (“PSLS”), provided certain balance sheet management and risk mitigation advisory services as well as loan valuation services to Seacoast in 2022 for which Piper Sandler Hedging and PSLS received approximately $20,000 and $35,000 in compensation, respectively. In the two years preceding the date of Piper Sandler’s opinion Piper Sandler did not provide any investment banking services to Professional; provided, however, Piper Sandler Hedging provided certain balance sheet and risk mitigation advisory services to Professional in 2021 and 2022 for which PSLS received an aggregate fee of approximately $80,000. In addition, in the ordinary course of our business as a broker-dealer, we may purchase securities from and sell securities to Seacoast, Professional and their respective affiliates. Piper Sandler may also actively trade the equity and debt securities of Seacoast and Professional for Piper Sandler’s own account and for the accounts of Piper Sandler’s customers.

Opinion of Professional’s Financial Advisor

On April 22, 2022, Professional engaged Stephens to act as its exclusive financial advisor in connection with any proposed transaction involving Professional and one or more parties in which Professional and its subsidiary, Professional Bank, would be acquired by or combined with a purchaser and/or one or more of its subsidiaries. As part of its engagement, Stephens was asked to undertake a study of the fairness, from a financial point of view, of the consideration payable in connection with any proposed transaction. Professional engaged Stephens because, among other factors, Stephens is a nationally recognized investment banking firm with substantial experience in similar transactions. As part of its investment banking business, Stephens is regularly engaged in the valuation of financial services businesses and their securities in connection with mergers and acquisitions.

57

As part of Stephens’ engagement, representatives of Stephens participated in a meeting of Professional’s board of directors held on August 5, 2022, at which the board of directors considered and approved the merger. At the meeting, Stephens reviewed the financial aspects of the merger and rendered its oral opinion, which was subsequently confirmed by delivery of a written opinion letter to the board of directors dated as of August 5, 2022, that, as of such date, the consideration to be received by the common shareholders of Professional (solely in their capacity as such) in the merger was fair to such shareholders from a financial point of view, based upon and subject to the qualifications, assumptions and other matters considered by Stephens in connection with the preparation of its opinion.

The full text of Stephens’ written opinion letter (the “Opinion Letter”) is attached as Appendix C to this proxy statement/prospectus. The Opinion Letter outlines the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by Stephens in rendering its opinion. The summary of the opinion set forth in this document is qualified in its entirety by reference to the full text of such written Opinion Letter. Investors are urged to read the entire Opinion Letter carefully in connection with their consideration of the merger. Except as otherwise noted in this section, Professional did not give any instruction to or impose any limitations on Stephens as it related to the issuance of its opinion.

Stephens’ opinion speaks only as of the date of the Opinion Letter, and Stephens has undertaken no obligation to update or revise its opinion. The opinion was directed to Professional’s board of directors (solely in its capacity as such) in connection with, and for purposes of, its consideration of the merger. The opinion only addresses whether the consideration to be received by the common shareholders of Professional (solely in their capacity as such) in the merger was fair to them from a financial point of view as of the date of the opinion. The opinion does not address the underlying business decision of Professional to engage in the merger or any other term or aspect of the merger agreement or the transactions contemplated thereby. Stephens’ opinion does not constitute a recommendation to Professional’s board of directors or any of Professional’s shareholders as to how such person should vote or otherwise act with respect to the merger or any other matter. Professional and Seacoast determined the merger consideration through a negotiation process.

In connection with developing its opinion, Stephens:

(i)

reviewed certain publicly available financial statements and reports regarding Professional and Seacoast;

(ii)

reviewed certain audited financial statements regarding Professional and Seacoast;

(iii)

reviewed certain internal financial statements, management reports and other financial and operating data concerning Professional and Seacoast prepared by management of Professional and management of Seacoast, respectively;

(iv)

reviewed, on a pro forma basis, in reliance upon consensus research estimates and upon financial projections and other information and assumptions concerning Professional and Seacoast provided by management of Professional and management of Seacoast, respectively, the effect of the merger on the balance sheet, capitalization ratios, earnings and tangible book value both in the aggregate and, where applicable, on a per share basis of Seacoast;

(v)

reviewed the reported prices and trading activity for the common stock of Professional and Seacoast;

(vi)

compared the financial performance of Professional and Seacoast with that of certain other publicly traded companies and their securities that Stephens deemed relevant to its analysis of the merger;

(vii)

reviewed the financial terms, to the extent publicly available, of certain merger or acquisition transactions that Stephens deemed relevant to its analysis of the merger;

(viii)

reviewed the then most recent draft of the merger agreement and related documents provided to Stephens by Professional;

(ix)

discussed with the management of Professional and the management of Seacoast the operations

58

of and future business prospects for Professional and Seacoast, respectively, and the anticipated financial consequences of the merger to Professional and Seacoast, respectively;

(x)

assisted in Professional’s deliberations regarding the material terms of the merger and Professional’s negotiations with Seacoast; and

(xi)

performed such other analyses and provided such other services as Stephens deemed appropriate.

Stephens relied on the accuracy and completeness of the information, financial data and financial forecasts provided to Stephens by Professional and Seacoast and of the other information reviewed by Stephens in connection with the preparation of its opinion, and its opinion was based upon such information. Stephens did not independently verify or undertake any responsibility to independently verify the accuracy or completeness of any of such information, data or forecasts. Management of Professional assured Stephens that they were not aware of any relevant information that had been omitted or remained undisclosed to Stephens. Stephens did not assume any responsibility for making or undertaking an independent evaluation or appraisal of any of the assets or liabilities of Professional or of Seacoast, and Stephens was not furnished with any such evaluations or appraisals; nor did Stephens evaluate the solvency or fair value of Professional or of Seacoast under any laws relating to bankruptcy, insolvency or similar matters. Stephens did not assume any obligation to conduct any physical inspection of the properties, facilities, assets or liabilities (contingent or otherwise) of Professional or Seacoast. Stephens did not receive or review any individual loan or credit files nor did Stephens make an independent evaluation of the adequacy of the allowance for loan and lease losses of Professional or Seacoast. Stephens did not make an independent analysis of the effects of the COVID-19 pandemic, the invasion of Ukraine, potential future changes in the inflation rate or other related market developments or disruptions, or of any other disaster or adversity, on the business or prospects of Professional or Seacoast. With respect to the financial forecasts prepared by management of Professional and management of Seacoast, including the forecasts of potential cost savings and potential synergies, Stephens assumed that such financial forecasts had been reasonably prepared by management of Professional and management of Seacoast, respectively, and reflected the best then currently available estimates and judgments of management of Professional and management of Seacoast, respectively, as to the future financial performance of Professional and Seacoast, respectively, and provided a reasonable basis for Stephens’ analysis. Stephens recognized that such financial forecasts were based on numerous variables, assumptions and judgments that were inherently uncertain (including, without limitation, factors related to general economic and competitive conditions) and that actual results could vary significantly from such forecasts, and Stephens expressed no opinion as to the reliability of such financial projections and estimates or the assumptions upon which they were based.

Stephens does not provide legal, accounting, regulatory, or tax advice or expertise, and Stephens relied solely, and without independent verification, on the assessments of Professional and its other advisors with respect to such matters. Stephens assumed, with Professional’s consent, that the merger will not result in any materially adverse legal, regulatory, accounting or tax consequences for Professional or its shareholders and that any reviews of legal, accounting, regulatory or tax issues conducted as a result of the merger will be resolved favorably to Professional and its shareholders. Stephens did not express any opinion as to any tax or other consequences that might result from the merger.

Stephens’ opinion was necessarily based upon market, economic and other conditions as they existed and could be evaluated on the date of the opinion, and on the information made available to Stephens as of the date of the opinion. Market price data used by Stephens in connection with its opinion was based on reported market closing prices as of August 3, 2022. It should be understood that subsequent developments may affect the opinion and that Stephens did not undertake any obligation to update, revise or reaffirm the opinion or otherwise comment on events occurring after the date of the opinion. Stephens further noted that the current volatility and disruption in the credit and financial markets relating to, among other things, the COVID-19 pandemic, the invasion of Ukraine or potential future changes in inflation rates may or may not have an effect on Professional or Seacoast, and Stephens did not express an opinion as to the effects of such volatility or such disruption on the merger or any party to the merger. Stephens further expressed no opinion as to the prices at which shares of Professional’s or Seacoast’s common stock may trade at any time subsequent to the announcement of the merger.

59

In connection with developing its opinion, Stephens assumed that, in all respects material to its analyses:

(i)

the merger and any related transactions will be consummated on the terms of the latest draft of the merger agreement provided to Stephens, without material waiver or modification;

(ii)

the representations and warranties of each party in the merger agreement and in all related documents and instruments referred to in the merger agreement are true and correct;

(iii)

each party to the merger agreement and all related documents will perform all of the covenants and agreements required to be performed by such party under such documents;

(iv)

all conditions to the completion of the merger will be satisfied within the time frames contemplated by the merger agreement without any waivers;

(v)

that in the course of obtaining the necessary regulatory, lending or other consents or approvals (contractual or otherwise) for the merger and any related transactions, no restrictions, including any divestiture requirements or amendments or modifications, will be imposed that would have a material adverse effect on the contemplated benefits of the merger to the common shareholders of Professional;

(vi)

there has been no material change in the assets, liabilities, financial condition, results of operations, business or prospects of Professional or Seacoast since the date of the most recent financial statements made available to Stephens, and that no legal, political, economic, regulatory or other development has occurred that will adversely impact Professional or Seacoast; and

(vii)

the merger will be consummated in a manner that complies with applicable law and regulations.

Stephens’ opinion was limited to whether the consideration to be received by the common shareholders of Professional (solely in their capacity as such) in the merger was fair to them from a financial point of view as of the date of the opinion. Stephens was not asked to include in its Opinion Letter, and it did not include in its Opinion Letter, any opinion as to the terms of the merger agreement or the form of the merger or any aspect of the merger, other than the fairness, from a financial point of view, of the consideration to be received in the merger by the common shareholders of Professional (solely in their capacity as such). The opinion did not address the merits of the underlying decision by Professional to engage in the merger, the merits of the merger as compared to other alternatives potentially available to Professional or the relative effects of any alternative transaction in which Professional might engage, nor is it intended to be a recommendation to any person or entity as to any specific action that should be taken in connection with the merger, including with respect to how to vote or act with respect to the merger. Moreover, Stephens’ Opinion Letter did not express any opinion as to the fairness of the amount or nature of the compensation to any of Professional’s officers, directors or employees, or to any group of such officers, directors or employees, whether relative to the compensation to other shareholders of Professional or otherwise.

The following is a summary of the material financial analyses performed and material factors considered by Stephens in connection with developing its opinion. Stephens performed certain procedures, including each of the financial analyses described below, and reviewed with Professional’s executive management and board of directors the assumptions upon which the analyses were based, as well as other factors. Although this summary does not purport to describe all of the analyses performed or factors considered by Stephens, it does set forth those analyses considered by Stephens to be material in arriving at its opinion. The preparation of a fairness opinion is a complex analytic process involving various determinations as to the appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances. Therefore, a fairness opinion is not readily susceptible to partial analysis or summary description. The order of the summaries of analyses described does not represent the relative importance or weight given to those analyses by Stephens. It should be noted that in arriving at its opinion, Stephens did not attribute any particular weight to any analysis or factor considered by it, but rather made qualitative judgments as to the significance and relevance of each analysis and factor. Accordingly, Stephens believes that its analysis must be considered as a whole and that considering any portion of such analyses and factors, without considering all analyses and factors as a whole, could create a misleading or incomplete view of the process underlying its opinion. The financial analyses summarized below include information presented in

60

tabular format. The tables alone do not constitute a complete description of the financial analyses summarized below. Accordingly, Stephens’ analyses and the summary of its analyses must be considered as a whole, and selecting portions of its 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 Stephens’ analyses and opinion.

Summary of Merger:

Pursuant to the merger agreement, and subject to the terms, conditions and limitations set forth therein, and for purposes of its opinion, Stephens understood that, subject to potential adjustments as described in the merger agreement, each outstanding share of Professional common stock will be converted into the right to receive 0.8909 shares of Seacoast common stock, which, based on Seacoast’s closing stock price of $36.45 on August 3, 2022, had an implied value as of that date of approximately $32.47 per share, resulting in the expected consideration to be exchanged by Seacoast for all of the outstanding common stock, restricted stock, appreciation rights and options in Professional having an aggregate value, as of that date, of approximately $484.4 million. Based upon the unaudited financial information of Professional as of and for the twelve months ended June 30th, 2022, and market data as of August 3rd, 2022, Stephens calculated the following implied transaction multiples:

Transaction Value / Reported Tangible Book Value (Aggregate):	233%
Transaction Value / Last Twelve Months (“LTM”) Earnings(1):	21.5x
Core Deposit Premium(2):	12.3%

Note: The last twelve months earnings of Professional is based on the most recent available financial statements prior to announcement.

(1)

LTM earnings excludes the impact of one-time charges related to former CEO’s departure.

(2)

The excess of the transaction value over tangible common equity expressed as a percentage of core deposits, which consist of total deposits less time deposit accounts with balances greater than $250,000.

Contribution Analysis — Professional:

Stephens considered market capitalization information and certain historical and projected financial information for Professional and Seacoast, and the exchange ratios implied thereby. Based on its analysis, Stephens calculated Professional’s range of contributions to the merger, across the metrics indicated below, of 12.2% to 20.2% for an implied exchange ratio range of 0.6792x to 1.2061x. This compares to the exchange ratio in the merger of 0.8909x, which results in a pro forma ownership of approximately 15.6% for Professional shareholders. The analysis is illustrated below.

Relevant Public Companies Analysis — Professional:

Stephens compared the financial condition, operating statistics and market valuation of Professional to certain public companies selected by Stephens and their respective public trading values. Stephens selected the companies outlined below because their relative asset size and financial performance, among other factors, were reasonably similar to those of Professional; however, no selected company below was identical or directly comparable to Professional. A complete analysis involves complex considerations and qualitative judgments concerning differences in financial and operating characteristics and other factors that could affect the public trading values of the relevant public companies. Mathematical analysis (such as determining the median) is not in itself a meaningful method of using relevant public company data.

Stephens selected the following public companies based on the criteria set forth below:

Nationwide major exchange-traded banks and thrifts with 2022Q1 total assets between $2 billion and $4 billion and last twelve months loan growth, excluding PPP, between 10% and 25%.

Discounted Cash Flow Analysis (Management Base Case) — Professional:

Stephens performed a discounted cash flow analysis for Professional using projections developed by Professional’s executive management through the end of 2024 and extrapolations for the period from January 2025 through December 2026 based upon assumptions provided by Professional management of a 7.0% asset growth rate and a maintenance in return on average assets of 1.40%. Stephens calculated a range of implied per share equity values for Professional based upon the discounted net present value of the projected after-tax free cash flows for the projected period (July 2022 through December 2026) and a terminal value at year-end 2026 based on a multiple of then next twelve months’ net income. To calculate an implied per share equity value range, Stephens considered discount rates ranging from 10.44% to 11.69% and terminal earnings multiples ranging from 9.0x to 13.0x. Based on this analysis, Stephens derived a range for the implied equity value of Professional from $23.50 per share to $35.70 per share.

Discounted Cash Flow Analysis (Consensus) — Professional:

Stephens performed a discounted cash flow analysis for Professional based upon consensus analyst estimates through the end of 2023 for the period from July 2022 through December 2023 and extrapolations for the period from January 2024 through December 2026 based upon consensus analyst estimates and assumptions provided by Professional management of a 7.0% asset growth rate and a maintenance in return on average assets of 1.00%. Stephens calculated a range of implied per share equity values for Professional based upon the discounted net present value of the projected after-tax free cash flows for the projected period (July 2022 through December 2026) and a terminal value at year-end 2026 based on a multiple of the next twelve months’ net income. To calculate an implied per share equity value range, Stephens considered discount rates from 10.44% to 11.69% and terminal earnings multiple range of 9.0x to 13.0x. Based on this analysis, Stephens derived a range for the implied equity value of Professional from $18.43 per share to $27.38 per share.

The discounted cash flow analysis is a widely used valuation methodology, but the results of this methodology are highly dependent on the assumptions that must be made, including asset and earnings growth rates, terminal values, capital levels, and discount rates. The foregoing discounted cash flow analyses do not purport to be indicative of the actual values or expected values of Professional. The actual results may vary from the projected results, any of these assumptions might not be realized in future operations and the variations may be material.

Relevant Nationwide Transactions Analysis — Professional Holding Corp:

Stephens reviewed certain publicly available transaction multiples and related financial data for transactions involving nationwide banks and thrifts announced since January 1, 2021 where (i) the deal value was publicly disclosed and (ii) the target’s assets were between $1.5 billion and $5 billion (excluding Merger of Equals, as defined by S&P Global Market Intelligence, transactions involving credit union acquirers and transactions where a private buyer issued stock). The following transactions were selected by Stephens because each target’s relative asset size, financial performance and operations, among other factors, was reasonably similar to Professional; however, no selected company or transaction below was identical or directly comparable to Professional or the merger (in each transaction, the acquirer is listed first, the target is listed second and the transaction announcement date is noted parenthetically):

Stephens considered these selected transactions to be reasonably similar, but not identical or directly comparable, to the merger. A complete analysis involves complex considerations and qualitative judgments concerning differences in the selected transactions and other factors that could affect the transaction values in those selected transactions as compared with the merger. Mathematical analysis (such as determining the median) is not in itself a meaningful method of using selected transaction data. Stephens compared certain transaction multiples implied by the merger to the 25th percentile, median and 75th percentile transaction multiples of the selected transactions for which data was available:

Pay-to-Trade multiple defined as transaction P/TBV divided by Buyer P/TBV.

Stephens then applied multiples of (x) 1.53x to 2.06x to Professional’s tangible book value as of June 30, 2022, and (y) 13.2x to 18.4x to Professional’s LTM EPS as of June 30, 2022. Stephens also applied percentages of core deposit premiums of 7.0% to 13.9% to Professional’s core deposits as of June 30, 2022. This analysis indicated the following ranges per share of Professional common stock.

Methodology	Illustrative Value Range
Tangible Book Value Per Share	​	$	23.16 – $31.15
Core LTM Non-GAAP EPS	​	$	20.93 – $29.06
Core Deposit Premium	​	$	23.39 – $35.11

Miscellaneous:

The preparation of a fairness opinion is a complex process and is not susceptible to a partial analysis or summary description. Stephens believes that its analyses must be considered as a whole and that selecting portions of its analyses, without considering the analyses taken as a whole, would create an incomplete view of the process underlying its opinion. In addition, Stephens considered the results of all such analyses and did not assign relative weights to any of the analyses, but rather made qualitative judgments as to significance and relevance of each analysis and factor, so the results from any particular analysis described above should not be taken to be the view of Stephens.

In performing its analyses, Stephens made numerous assumptions with respect to industry performance, general business, economic and regulatory conditions and other matters, many of which are beyond the control of Professional. The analyses performed by Stephens are not necessarily indicative of actual values, trading values or actual future results which might be achieved, all of which may be significantly more or less favorable than suggested by such analyses. The analyses do not purport to be appraisals or to reflect the prices at which companies may actually be sold, and such estimates are inherently subject to uncertainty.

Stephens is serving as financial adviser to Professional in connection with the merger and is entitled to receive a fee for such services (currently estimated at approximately $4.8 million), a significant portion of which is contingent upon the consummation of the proposed merger. Stephens also received a fee of $400,000 from Professional upon rendering its fairness opinion, which opinion fee will be credited in full against the fee which will become payable to Stephens upon the closing of the proposed merger. Professional has also agreed to indemnify Stephens against certain claims and liabilities that could arise out of Stephens’ engagement, including certain liabilities that could arise out of Stephens’ providing its opinion, and to reimburse Stephens for certain of its out-of-pocket expenses incurred in connection with the engagement.

Affiliates and employees of Stephens (including, among others, employees involved in preparing its fairness opinion), owned, in the aggregate, approximately two percent of the outstanding common stock of Professional. Stephens issued periodic research reports regarding the business and prospects of Professional prior to the recent departure of its research analyst who was covering Professional and Seacoast. Stephens makes a market in the stock of Professional. While Stephens has not received fees for providing investment banking or other services to Professional or Seacoast within the past two years, Stephens served as the lead left bookrunner in connection with the initial public offering of Professional’s common stock, which priced on February 6, 2020 and as financial advisor to Professional in connection with its acquisition of Marquis Bancorp, Inc., which closed on March 26, 2020, and Stephens received customary fees in connection with such assignments. Stephens expects to pursue future investment banking services assignments with participants in the merger.

In the ordinary course of its business, Stephens and its affiliates and employees at any time may hold long or short positions, and may trade or otherwise effect transactions as principal or for the accounts of customers, in debt, equity or derivative securities of participants in the merger.

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 Professional common stock that exchange their shares of Professional 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 Professional 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 Professional common stock.

This discussion addresses only those Professional common shareholders that hold their shares of Professional 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;

•

a holder of Professional 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 Professional 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 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 Professional 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.

69

If a partnership (including for this purpose any entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds Professional 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 Professional 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. The opinion of Alston & Bird LLP provided on behalf of Seacoast will be based on representation letters provided by Seacoast and Professional and on customary factual assumptions. The opinion described above will not be binding on the Internal Revenue Service or any court. Professional 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 the opinion is 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 Professional will be a party to such reorganization within the meaning of Section 368(b) of the Code, and neither Seacoast nor Professional 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 Professional common stock that exchanges all of your Professional 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.

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 Professional 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 Professional shares surrendered.

If a U.S. holder acquired different blocks of Professional 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 Professional 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 Professional 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 Professional 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 Professional common stock actually or constructively owns shares of Seacoast common stock (other than the shares of Seacoast common stock received as consideration in

70

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 Professional common stock in the merger is complex and must be determined on a shareholder-by-shareholder 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 Professional shareholder who receives Seacoast common stock as a result of the merger will be required to retain records pertaining to the merger. Each Professional 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 Professional shareholder’s basis in the Professional common stock surrendered and the fair market value of the Seacoast common stock received in the merger. A “significant holder” is a holder of Professional common stock who, immediately before the merger, owned at least 1% (by vote or value) of the outstanding stock of Professional or securities of Professional with a basis for U.S. federal income tax purposes of at least $1 million.

This discussion of certain material U.S. federal income tax consequences is for general information purposes only and is not tax advice. Holders of Professional 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 Professional 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, Professional’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 Federal Reserve and the bank merger must be approved by the OCC. Once the Federal Reserve approves the merger (unless such requirement for approval has been waived), the parties must wait for up to 30 days before completing the merger. With the concurrence of the U.S. Department of Justice and permission from the Federal Reserve, however, the

71

merger may be completed on or after the fifteenth (15th) day after approval from the Federal Reserve (unless such requirement for approval has been waived). Similarly, after receipt of approval of the bank merger from the OCC, the parties must wait for up to 30 days before completing the bank 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 bank 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 dates of such approvals. There also can be no assurance that the regulatory approvals received will not contain any conditions 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” beginning on page      .

No Appraisal Rights for Professional Shareholders

Under Section 607.1302 of the FBCA, the holders of Professional common stock will not be entitled to appraisal or dissenters’ rights in connection with the merger if, on the record date for the Professional special meeting, Professional common stock is listed on a national securities exchange. Professional common stock is currently listed on the NASDAQ, a national securities exchange, and is expected to continue to be so listed on the record date for the Professional special meeting. In addition, the holders of Professional common stock will receive shares of Seacoast common stock as consideration in the merger, which shares are currently listed on the NASDAQ, and are expected to continue to be so listed at the effective time. Accordingly, the holders of Professional common stock are not entitled to any appraisal or dissenters’ rights in connection with the merger.

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

The members of the boards 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 corporation and 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, 2021 and its definitive proxy statement on Schedule 14A for its 2022 annual meeting, filed with the SEC on April 12, 2022. See “Where You Can Find More Information” and “Documents Incorporated by Reference” beginning on pages     and    , respectively.

Interests of Professional Directors and Executive Officers in the Merger

In the merger, the directors and executive officers of Professional will receive the same merger consideration for their Professional shares as the other Professional shareholders. In considering the recommendation of the Professional board of directors that you vote to approve the merger agreement, you should be aware that some of the executive officers and directors of Professional 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 Professional shareholders generally. The Professional 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 Professional shareholders vote in favor of approving the merger agreement. See “The Merger — Background of the Merger” and “The Merger — Professional’s Reasons for the Merger and Recommendations of the Professional Board of Directors” beginning on pages     and   , respectively. Professional’s shareholders should take these interests into account in deciding whether to vote “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 Professional Equity Awards

The merger agreement provides that all stock options issued by Professional will cease to be outstanding at the effective time. In consideration of such termination, Seacoast will grant to each holder of Professional 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 Professional 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 Professional common stock subject to such Professional 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 Professional common stock at which such Professional option was exercisable immediately prior to the effective time by (y) the exchange ratio, rounded up to the nearest whole cent.

At the effective time of the merger, each share of Professional common stock that is subject to a Professional restricted stock award that is outstanding immediately prior to the effective time shall, by virtue of the merger, automatically be vested and converted into the right to receive the merger consideration.

Prior to the effective time of the merger, Professional shall cause each Professional stock appreciation right that is outstanding to be vested and exercised for a number of shares of Professional common stock determined pursuant to the terms of the applicable stock appreciation right award agreement, subject to applicable withholding. At the effective time, each share of Professional common stock issuable as a result of such exercise of Professional stock appreciation rights shall, by virtue of the merger, automatically be vested and converted into the right to receive the merger consideration.

The number of unvested Professional stock options, Professional restricted stock awards, and Professional stock appreciation rights held by the executive officers of Professional is as follows, as of the date of this proxy statement/prospectus: [•]

Change in Control Payments under Employment Agreements

Professional Bank is currently a party to an employment agreement with Ryan Gorney and a change in control agreement with Michael Sontag. Each of these agreements provides for the payment of a cash change in control bonus in connection with the closing of the merger. The change in control bonuses are equal to two times the executive’s then-current salary and his bonus earned for the calendar year ended immediately prior to the year in which the closing occurs. The total change in control bonus payments for these executives are estimated to be $[•] for Mr. Gorney and $[•] for Mr. Sontag. Mr. Iglesias, and Ms. Usategui are also parties to similar employment agreements with Professional Bank, but their rights to receive change in control bonuses are being terminated in connection with their new employment agreements with Seacoast Bank, as described below.

New Employment Agreements

Each of Mr. Iglesias, Mr. Gorney, and Ms. Usategui has entered into an employment agreement with Seacoast Bank, effective as of the effective date of the merger. Upon their effectiveness, these new employment agreements will supersede and replace the current employment agreements these executives have with Professional Bank, including any severance and change in control payments contemplated thereunder, except that Mr. Gorney’s right to receive a change in control bonus upon the closing of the merger, as described above, shall remain in effect.

Pursuant to these new employment agreements, each of Mr. Iglesias, Mr. Gorney and Ms. Usategui will serve as officers of Seacoast Bank. Each employment agreement has a term that starts on the effective date of the merger and continues until the third anniversary of the effective date (for Mr. Iglesias) or the second anniversary of the effective date (for Mr. Gorney, and Ms. Usategui).

The new employment agreements set the initial base salaries for Mr. Iglesias, Mr. Gorney and Ms. Usategui at $[•], $[•] and $[•], respectively, and provide that these three officers will be eligible to receive such bonuses and stock awards as may be authorized by the Seacoast board of directors from time to

73

time, provided that Mr. Iglesias’ annual bonus for fiscal year 2023 will not be less than $[•], his annual bonus for each of fiscal years 2024 and 2025 will not be less than $[•], and Mr. Gorney’s and Ms. Usategui’s annual bonuses for fiscal year 2023 will not be less than $[•] and $[•], respectively. Pursuant to the new employment agreements, the annual long-term incentive opportunities for Mr. Iglesias, Mr. Gorney and Ms. Usategui will be equal to $[•], $[•] and $[•], respectively, and following the closing, Ms. Usategui will receive an award of restricted shares of Seacoast common stock having a value equal to $[•] on the grant date.

Pursuant to the new employment agreements, each of Mr. Iglesias and Ms. Usategui will be eligible to receive a maximum retention bonus equal to $[•] and $[•], respectively, a portion of which ($[•] and $[•], respectively) will be paid on the first payroll date following the effective date of the merger, and the remainder of which shall be paid in equal installments on the first payroll date following each of the first four six-month anniversaries of the effective date. Any unpaid retention bonus amounts will be forfeited if Mr. Iglesias or Ms. Usategui is terminated for “cause” or resigns without “good reason,” as such terms are defined in the new employment agreement, or if he or she breaches any of the restrictive covenants contained in the new employment agreement.

In the event Mr. Iglesias’, Mr. Gorney’s or Ms. Usategui’s employment is terminated by Seacoast Bank other than for cause, death or disability, or any of them resigns for good reason, he or she will be entitled to receive (i) each of the minimum bonus amounts provided in the employment agreement, to the extent not yet paid, which bonuses will be paid at the same time that the annual bonuses are paid to officers of Seacoast Bank for such respective years, (ii) severance equal to the amount of base salary that he or she would have earned over the remainder of the term of the agreement, payable in monthly installments, and (iii) for Mr. Iglesias and Ms. Usategui, any remaining retention bonus amounts, paid on their normal payment dates, conditioned upon his or her continuing compliance with the restrictive covenants through such dates. The restrictive covenants in the new employment agreements include non-competition, non-recruitment of certain employees, and non-solicitation of certain customers, each for a number of years following the effective date (three years for Mr. Iglesias and two years for Mr. Gorney and Ms. Usategui), and covenants prohibiting the disclosure of confidential information.

Director Restrictive Covenant Agreement; Claims Letters

Each director of Professional and Professional Bank has entered into a restrictive covenant agreement, covering a three-year period commencing with the effective time of the merger, with Seacoast in the form attached as Exhibit D to the merger agreement attached as Appendix A to this proxy statement/prospectus. In addition, certain officers and directors of Professional have entered into a claims letter in the form attached as Exhibit C to the merger agreement attached as Appendix A to this proxy statement/prospectus, by which they have agreed to release certain claims against Professional, effective as of the effective time of the merger.

Indemnification and Insurance

As described under “The Merger Agreement — Indemnification and Directors’ and Officers’ Insurance,” after the effective time of the merger, Seacoast will indemnify and defend the present and former directors, officers and employees of Professional and its subsidiaries against claims pertaining to matters occurring at or prior to the closing of the merger as permitted by Professional’s articles of incorporation, bylaws and the FBCA. 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 Professional pursuant to Professional’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 Professional.

Severance Benefits

In connection with the merger, employees of Professional, including officers (except for any officers of Professional who receive change in control benefits in connection with an existing employment or retention agreement or the Employment Agreements), whose employment terminates during the six-month period following the closing of the merger, other than for cause or as a result of death, disability, or unsatisfactory job performance, will be entitled to receive a severance payment equal to two (2) weeks’ pay for each year

74

of employment with Professional as of such date of termination, with a four (4) week minimum and a twenty (20) week maximum, if such employee is classified an exempt employee within the meaning of the Code. 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 Professional as of the date of such termination, with a two (2) week minimum and a ten (10) week maximum.

75

PROPOSAL 2: ADJOURNMENT OF THE PROFESSIONAL SPECIAL MEETING

Professional shareholders are being asked to approve the adjournment proposal.

If this adjournment proposal is approved, the Professional special meeting could be adjourned to any date. If the Professional special meeting is adjourned, Professional shareholders who have already submitted their proxies will be able to revoke them at any time prior to their use. If you sign and return a proxy and do not indicate how you wish to vote on the adjournment proposal, your shares of Professional common stock will be voted in favor of the adjournment proposal.

The adjournment proposal will be approved if the votes of Professional common stock cast in favor of the adjournment proposal, in person or by proxy at the special meeting, exceed the votes cast against the adjournment proposal.

THE PROFESSIONAL BOARD OF DIRECTORS RECOMMENDS THAT PROFESSIONAL SHAREHOLDERS VOTE “FOR” THE APPROVAL OF THE ADJOURNMENT PROPOSAL.

THE MERGER AGREEMENT

This section of the proxy statement/prospectus describes the material terms of the merger agreement. The description in this section and elsewhere in this proxy statement/prospectus is subject to, and qualified in its entirety by reference to, the complete text of the merger agreement, which is attached as Appendix A to this document and incorporated by reference herein. This summary does not purport to be complete and may not contain all of the information about the merger agreement that is important to you. We urge you to read the full text of the merger agreement, as it is the legal document governing the mergers. This section is not intended to provide you with any factual information about Professional or Seacoast. Such information can be found elsewhere in this proxy statement/prospectus and in the public filings that each of Professional and Seacoast makes with the SEC, as described in the section entitled “Where You Can Find More Information” beginning on page    of this proxy statement / prospectus.

Explanatory Note Regarding the Merger Agreement

The merger agreement and this summary of terms are included to provide you with information regarding the terms of the merger agreement. Factual disclosures about each of Professional and Seacoast contained in this proxy statement/prospectus or in the public reports of each of Professional and Seacoast filed with the SEC may supplement, update or modify the factual disclosures about Professional and Seacoast contained in the merger agreement. The merger agreement contains representations and warranties by Professional, on the one hand, and representations and warranties by Seacoast, on the other hand, made solely for the benefit of the other. The representations, warranties and covenants made in the merger agreement by Professional and Seacoast were qualified and subject to important limitations agreed to by Professional and Seacoast in connection with negotiating the terms of the merger agreement. In particular, in your review of the representations and warranties contained in the merger agreement and described in this summary, it is important to bear in mind that the representations and warranties were negotiated with the principal purpose of establishing circumstances in which a party to the merger agreement may have the right not to consummate the merger if the representations and warranties of the other party prove to be untrue due to a change in circumstance or otherwise, and allocating risk between the parties to the merger agreement, rather than establishing matters as facts. The representations and warranties also may be subject to a contractual standard of materiality different from that generally applicable to shareholders and reports and documents filed with the SEC or other regulatory bodies, and some were qualified by the matters contained in the confidential disclosure schedules that Professional and Seacoast each delivered in connection with the merger agreement and certain documents filed with the SEC. Moreover, information concerning the subject matter of the representations and warranties, which do not purport to be accurate as of the date of this proxy statement/prospectus, may have changed since the date of the merger agreement. Accordingly, the representations and warranties in the merger agreement should not be relied on by any person as characterizations of the actual state of facts about Professional or Seacoast at the time they were made or otherwise and should be read only in conjunction with the other information provided elsewhere in this proxy statement/prospectus or incorporated by reference into this proxy statement/prospectus. Please see the section entitled “Where You Can Find More Information.”

The Merger and the Bank Merger

The boards of directors of Seacoast and Professional have each unanimously approved and adopted the merger agreement, which provides for the merger of Professional with and into Seacoast, with Seacoast as the surviving company in the merger.

The merger agreement also provides that immediately after the effective time of the merger, Professional Bank, a wholly owned subsidiary of Professional, will merge with and into SNB, with SNB surviving the merger as the surviving bank in the merger. Each share of Professional common stock outstanding immediately prior to the effective time of the merger (excluding shares held by Professional, SNB, Professional Bank, Seacoast and their wholly owned subsidiaries) 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.

77

All shares of Seacoast common stock received by Professional 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

Seacoast and Professional will use their reasonable best efforts to cause the closing to occur on or before February 28, 2023, provided that if such date is not practicable, a mutually agreeable date, which will be no later than ten business days following the date on which satisfaction or waiver of all closing conditions has occurred (other than those conditions that by their nature can only be satisfied at the closing, but subject to the satisfaction and waiver thereof), which is the date when the effective time is to occur, unless otherwise agreed to by the parties. Simultaneously with the closing of the merger, Seacoast will file articles of merger with the Secretary of State of the State of Florida. The merger will become effective at such time as the articles of merger are filed or such other time as may be specified in the articles of merger.

We currently expect that the merger will be completed in the first quarter of 2023, subject to the approval of the merger agreement by Professional shareholders, the approval of the bank merger agreement by 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 Professional will complete the merger. See “The Merger Agreement — Conditions to Completion of the Merger” beginning on page   .

Merger Consideration

Under the terms of the merger agreement, each share of Professional common stock outstanding immediately prior to the effective time of the merger (excluding certain shares held by Professional, Seacoast and their wholly owned subsidiaries) will be converted into the right to receive 0.8909 shares of Seacoast common stock (which we refer to as the “merger consideration,”). Please see “The Merger Agreement — Consideration” beginning on page   for more information. If, as of the close of business on the fifth business day prior to the closing date, Professional’s consolidated tangible shareholders’ equity is less than $224.50 million (less the after-tax impact of permitted expenses) or Professional Bank’s general allowance for loan and lease losses is less than 0.75% of total loans and leases outstanding (excluding loan originated under the PPP), Seacoast shall have the option to adjust the merger consideration downward, including a corresponding downward adjustment to the exchange ratio, or terminate the merger agreement.

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 ten (10) 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 Professional 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.

If Seacoast or Professional change the number of shares of Seacoast common stock or Professional common stock outstanding prior to the effective time of the merger as a result of a reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split or similar recapitalization with respect to the Seacoast common stock or Professional common stock, then the merger consideration shall be appropriately and proportionately adjusted.

Based upon the closing sale price of the Seacoast common stock on the NASDAQ Global Select Market of $      on      , 2022, the last practicable trading date prior to the printing of this proxy statement/​prospectus, each share of Professional 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 Professional shareholders in the merger will fluctuate between now and the closing date of the merger. We make no assurances as to whether

78

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.”

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 Professional common stock, including holders of the Professional equity awards who received Professional common stock in accordance with the exercise of such Professional equity awards prior to the effective time, transmittal materials for use in exchanging such holder’s Professional certificates or electronic book-entry shares 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 Professional 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.

On or before the closing date, the stock transfer books of Professional will be closed and there will be no further transfers on the stock transfer books of Professional.

Organizational Documents of Surviving Holding Company and Surviving Bank; Directors and Officers

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

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

Conduct of Business Pending the Merger

Professional has further agreed to use its reasonable best efforts to cause such 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.

Each of Seacoast and Professional 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 Professional 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 Professional 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 Professional will 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 will keep the other apprised of the status of material matters relating to the completion of the transactions contemplated by the merger agreement.

Seacoast and Professional 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 Professional 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.

In connection with seeking regulatory approval for the merger, Seacoast is not required to agree to any condition or consequence that would, after the effective time of the merger, have a material adverse effect on Seacoast or any its subsidiaries, including Professional.

82

NASDAQ Listing

Seacoast has agreed to cause the shares of Seacoast common stock to be issued to the holders of Professional common stock in the merger to be authorized for listing on the NASDAQ Global Select Market, subject to official notice of issuance, prior to the effective time of the merger. Seacoast has also agreed to cause the shares of Seacoast common stock that will be issued upon the exercise of substitute Seacoast options to be reserved for issuance and registered with the SEC and approved for listing on the NASDAQ Global Select Market, subject to official notice of issuance, no later than five business days after the effective time.

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 Professional 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 Professional 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.

With respect to any Seacoast health, dental, vision or other welfare plan in which any covered employee is eligible to participate following the closing date of the merger, 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 Professional 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 six months after the effective time of the merger, any covered employee (other than those who receive certain payments or retention benefits pursuant to agreements with Professional) 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 equal to its severance policies.

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 Professional 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 the fact that such person is or was a director, officer or employee of Professional or its subsidiaries, or the merger agreement or any of the transactions contemplated by the merger agreement, to the same extent as such persons are indemnified or have the right to advancement of expenses pursuant to the organizational documents of Professional and the FBCA. All existing rights to indemnification and all existing limitations on liability existing in favor of the directors, officers and employees of Professional as provided in its organizational documents shall survive the merger and continue in full force and effect and shall be honored by Seacoast.

For a period of no less than six years after the effective time of the merger, Seacoast will provide directors’ and officers’ liability insurance that serves to reimburse the officers and directors of Professional at or prior to the effective time of the merger with respect to claims against them arising from facts or events occurring at or before the effective time of the merger (including the transactions contemplated by the

83

merger agreement). The directors’ and officers’ liability insurance will contain at least the same coverage and amounts, and contain terms and conditions no less advantageous to the indemnified person as the coverage currently provided by Professional provided, however, that Seacoast may substitute policies of at least the same coverage and amounts containing terms and conditions that are not less advantageous than such Professional policy; provided further that in no event will the aggregate premiums applicable to such coverage exceed 150% of the current annual premium paid by Professional for such insurance.

Third Party Proposals

Professional has agreed that it will not, and will cause its directors, officers, employees and representatives and affiliates not to: initiate, solicit, knowingly encourage or facilitate inquiries or proposals with respect to, or engage or participate in any negotiations concerning, or provide to any person any confidential or nonpublic information or data or have or participate in any discussions with any person relating to, any (i) merger, consolidation, share exchange, business combination, reorganization, recapitalization, liquidation, dissolution or other similar transaction involving Professional or its subsidiaries, (ii) tender or exchange offer, that if consummated, would result in any third-party owning 25% or more of any class of equity or voting securities of Professional or Professional Bank, (iii) acquisition or purchase, direct or indirect, of 25% or more of the consolidated assets of Professional and its subsidiaries or 25% or more of any class of equity or voting securities of Professional or Professional Bank, or (iv) 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 (items (i)-(iv) collectively referred to as an “acquisition proposal”).

However, the merger agreement provides that at any time prior to the approval of the merger agreement by the Professional shareholders, if Professional receives an unsolicited acquisition proposal that does not violate the “no shop” provisions in the merger agreement and Professional 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 Professional may furnish non-public information or data to the third party making the acquisition proposal and participate in such negotiations or discussions with the third party making the acquisition proposal regarding such proposal, if the Professional board of directors determines in good faith (and based upon the written advice of its outside counsel) that failure to take such actions would reasonably be expected to result in a breach of its fiduciary obligations to the Professional shareholders under applicable law and if Professional enters into a confidentiality agreement with such third party. Professional must promptly advise Seacoast in writing within twenty-four hours following receipt of any acquisition proposal and the substance of such proposal and must keep Seacoast apprised of any related developments, discussions and negotiations (including the terms and conditions of the acquisition proposal) 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 Professional common stock on terms that the Professional board of directors concludes in good faith to be more favorable to the shareholders from a financial point of view than the merger and the other transactions contemplated by the merger agreement (including taking into account the terms, if any, proposed by Seacoast to amend or modify the terms of the transactions contemplated by the merger agreement in response to such proposal), (i) after receiving the written advice of its financial advisor, (ii) after taking into account the likelihood of consummation of such transaction on the terms set forth therein (as compared to, and with due regard for, the terms set forth in 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 the proposal and any other relevant factors permitted under applicable law, is more favorable to the Professional 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 Professional’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 Professional board of directors set forth in this proxy statement/prospectus that the Professional shareholders vote to approve the merger agreement, or from making or causing to be made any third party

84

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 Professional shareholders, however, the Professional board of directors may effect a change in recommendation in response to a bona fide, unsolicited, written acquisition proposal that the Professional board of directors concludes in good faith that there is a reasonable likelihood that such acquisition proposal constitutes or is reasonably likely to result in a superior proposal and if the board concludes in good faith (and based upon the written advice of its outside legal counsel) that the failure to accept such superior proposal would reasonably be expected to result in a breach of its fiduciary obligations to Professional shareholders under applicable law, then the board may terminate the merger agreement and enter into a definitive agreement with respect to such superior proposal.

The Professional board of directors may not make a change in recommendation, or terminate the merger agreement to pursue a superior proposal, unless: (i) Professional has not breached any of the provisions of the merger agreement relating to third party acquisition proposals in any respect; (ii) the Professional board of directors determines in good faith (after consultation with outside legal counsel and its financial advisors) that such superior proposal 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) Professional has given Seacoast at least four 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, Professional 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 material change to the terms of a superior proposal, Professional 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 Professional board of directors makes a change in recommendation, if Professional terminates the merger agreement to enter into an agreement with respect to a superior proposal, or if Professional’s shareholders do not approve the merger agreement and Professional enters into an agreement with respect to an acquisition proposal within twelve months from the date the merger agreement is terminated, Professional could be required to pay Seacoast a termination fee of $21.79 million in cash. See “The Merger Agreement — Termination,” and “The Merger Agreement — Termination Fee.”

Approval of 280G Payments

To the extent any payments or benefits made with respect to, or which could arise as a result of, the merger agreement or the transactions contemplated thereby, could be characterized as an “excess parachute payment” within the meaning of Section 280G(b)(1) of the Code, Professional shall, prior to the closing date, cooperate in good faith with Seacoast to effect reasonable measures to minimize any such payments or benefits from being characterized as “excess parachute payments” within the meaning of Section 280G(b)(1) of the Code.

Systems Integration; Operating Functions

From and after the date of the merger agreement, Professional shall and shall cause Professional Bank and its directors, officers and employees to and shall make all commercially reasonable best efforts (without undue disruption to their business) to cause Professional Bank’s data processing consultants and software providers to, cooperate and assist Professional and Seacoast in connection with an electronic and systems conversion of all applicable data of Professional and Professional Bank to the Seacoast systems, including the training of Professional and Professional Bank employees during normal banking hours. Additionally, Professional shall provide Seacoast access to its data files to facilitate the conversion process, including but not limited to (i) sample data files with data dictionary no later than 30 days following the date of the merger agreement, (ii) a full set of data files, including electronic banking and online bill payment data, for mapping and mock conversion no later than 180 days prior to the targeted conversion date as determined by Seacoast, (iii) a second full set of data files from which to establish CIS records, deposit shells, electronic

85

banking accounts, bill payment, payees and order debit cards no later than 45 days prior to the targeted conversion date, and (iv) a final set of data files no later than the date of the targeted conversion date. Professional shall coordinate and participate in regular meetings between data processing vendors and Seacoast representatives, to begin within 30 days following the date of the merger agreement, to facilitate system integration. Prior to the effective time, Professional shall take any action that Seacoast may reasonably request to facilitate the combination of the operations of the respective banks and Professional shall allocate and apply resources with appropriate expertise and authority to effectuate such requests. Professional shall cooperate with Seacoast in connection with the planning for the efficient and orderly combination of the parties and the operation of SNB after the merger, and in preparing for the consolidation of appropriate operating functions to be effective at the effective time of the merger, or such later time as may be decided by Seacoast. Professional shall provide office space and support services in connection with the foregoing, and senior officers of Professional and Seacoast shall meet from time to time as Professional or Seacoast may reasonably request, to review the financial and operational affairs of Professional and its subsidiaries, and Professional shall give due consideration to Seacoast’s input on such matters, with the understanding that, neither Seacoast nor SNB will be permitted to exercise control of Professional or Professional Bank prior to the effective time of the merger and Professional and Professional Bank shall not be under any obligation to act in a manner that could reasonably be deemed to constitute anti-competitive behavior under federal or state antitrust laws. Professional will be responsible for all conversion and deconversion fees and expenses, regardless of whether the merger becomes effective.

Seacoast Advisory Board

Seacoast has agreed to form an advisory board in Professional Bank’s current market area and has agreed to extend an invitation to each member of the Professional board of directors immediately prior to the effective time to serve on such advisory board provided that such directors have entered into a claims letter and restrictive covenant agreement.

Except in the case of a willful breach of the merger agreement, the payment of the termination fee will fully discharge Professional from any losses that may be suffered by Seacoast arising out of the termination of the merger agreement.

Waiver; Amendment

The merger agreement, including the disclosure letters and exhibits, may be amended at any time before the effective time of the merger, by subsequent writing signed by each of the parties, whether before or after the Professional shareholders have approved the transactions contemplated by the merger agreement, except to the extent that any such amendment would require the approval of the shareholders, unless such required approval is obtained.

The merger agreement, including the disclosure letters and exhibits, may be amended at any time before or after approval of the matters presented in connection with the merger by Professional, in writing signed on behalf of each of the parties, provided that after any approval of the transactions contemplated by the merger agreement by the Professional shareholders, there may not be, without further approval of the Professional shareholders, any amendment of the merger agreement that requires the approval of Professional shareholders.

Any agreement on the part of a party to any extension or waiver must be in writing signed on behalf of such party by a duly authorized officer of such party. Any such extension or

90

waiver or failure to insist on strict compliance with an obligation, covenant, agreement or condition will not operate as a waiver of any subsequent or other failure.

Expenses

Regardless of whether the merger is completed, all expenses incurred in connection with the merger, the merger agreement and other transactions contemplated thereby will be paid by the party incurring the expenses, except that Seacoast has paid the filing fee for the Registration Statement on Form S-4 of which this proxy statement/prospectus is a part and will pay any other filings fees with the SEC in connection with the merger and Seacoast will pay one half of the costs and expenses of printing and mailing this proxy statement/prospectus.

Governing Law

COMPARISON OF SHAREHOLDERS’ RIGHTS

Seacoast and Professional 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.

In addition, under Federal Reserve policy, 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.

BUSINESS OF PROFESSIONAL HOLDING CORP.

General

Professional Holding Corp., a Florida corporation, is the bank holding company for Professional Bank, a Florida banking corporation. Professional is registered as a financial holding company pursuant to the Bank Holding Company Act of 1956, as amended, and is subject to supervision and regulation by the Board of Governors of the Federal Reserve System and the Florida Office of Financial Regulation. Professional was incorporated in 2014 and is headquartered in Coral Gables, Florida. Professional operates primarily through its wholly owned subsidiary, Professional Bank, a Florida state-chartered bank, which commenced operations in 2008. Professional focuses on providing creative, relationship-driven commercial banking products and services designed to meet the needs of its clients. Professional’s clients are small to medium sized businesses, the owners and operators of these businesses, and other professionals and entrepreneurs. Professional conducts its banking operations from 9 branch locations in the Miami-Fort Lauderdale-Pompano Beach metropolitan statistical area, or MSA, which encompasses three rapidly growing counties in Florida: Miami-Dade, Broward, and Palm Beach. Additionally, Professional has a Digital Innovation Center located in Cleveland, Ohio, Loan Production Offices in St. Petersburg and Jacksonville, Florida, and a Loan Production Office in Bedford, New Hampshire that specializes in search fund lending.

As of June 30, 2022, Professional had total consolidated assets of approximately $2.66 billion, total consolidated deposits of approximately $2.38 billion, total consolidated net loans of approximately $1.97 billion, and total consolidated shareholders’ equity of approximately $233.6 million.

Business

Professional Bank provides a range of consumer and commercial banking services to individuals, businesses, and industries. The basic services offered by Professional Bank include: demand deposit interest bearing and noninterest bearing accounts, money market deposit accounts, savings accounts, time deposits, self-service safe deposit boxes, direct deposit, notary services, cashier’s checks, domestic and international collections, savings bond redemptions, with membership in the Star and Presto ATM networks, (MasterCard) debit cards, drive-through tellers, night depository, banking by mail, online banking and online bill payment services. Professional Bank offers consumer loans, both collateralized and uncollateralized, and Home Equity Lines of Credit (HELOC). In addition, Professional Bank makes secured and unsecured commercial and real estate loans, Small Business Administration (SBA) government guaranteed loans, and issues financial and stand-by letters of credit.

Professional Bank’s target market is consumers, professionals, small businesses, and commercial real estate investors. The small business customer (typically a commercial entity with sales of $20 million or less) has the opportunity to generate significant revenue for Professional Bank yet is generally underserved by large bank competitors. These customers generally can afford Professional Bank more profitability opportunities than the average retail customer.

The revenues of Professional Bank are primarily derived from interest on, and fees received in connection with, real estate and other loans, from interest and dividends from investment securities, service charge income generated from demand accounts, gain on sale of government guaranteed loans, and ATM fees. The principal sources of funds for Professional Bank’s lending activities are its deposits (primarily commercial deposits), loan repayments, and proceeds from investment securities. The principal expenses of Professional Bank are the interest paid on deposits, operating and general administrative expenses.

As is the case with banking institutions generally, Professional Bank’s operations are materially and significantly influenced by general economic conditions and by related monetary and fiscal policies of

102

financial institution regulatory agencies, including the Federal Reserve and the FDIC. Deposit flows and costs of funds are influenced by interest rates on competing investments and general market rates of interest. Lending activities are affected by the demand for financing of real estate and other types of loans, which in turn is affected by the interest rates at which such financing may be offered and other factors affecting local demand and availability of funds. Professional Bank faces strong competition in the attraction of deposits (the primary source of lendable funds) and in the origination of loans. See “Competition” below.

Banking Services

Commercial Banking.   Professional Bank focuses its commercial loan originations on small and mid-sized business (generally up to $20 million in annual sales) and such loans are usually accompanied by significant related deposits. Commercial underwriting is driven by cash flow analysis supported by collateral analysis and review. Commercial loan products include commercial real estate construction and term loans; working capital loans and lines of credit; demand, term and time loans; and equipment, inventory and accounts receivable financing. Professional Bank offers a range of cash management services and deposit products to commercial customers. Online banking is currently available to commercial and consumer customers.

Retail Banking.   Professional Bank’s retail banking activities emphasize consumer deposit and checking accounts. An extensive range of these services is offered by Professional Bank to meet the varied needs of its customers from young persons to senior citizens. In addition to traditional products and services, Professional Bank offers contemporary products and services such as debit cards, mutual funds and annuities, internet banking and electronic bill payment services. Consumer loan products offered by Professional Bank include home equity lines of credit, second mortgages, new and used auto loans, new and used boat loans, overdraft protection, and unsecured personal credit lines.

Government Guaranteed Lending.   Professional Bank makes SBA loans underwritten and structured to provide a source of fee income largely from the process of originating product for sale of the guaranteed portion on the secondary market.

Employees

As of June 30, 2022, Professional Bank employed 210 full-time employees and two part-time employees. The employees are not represented by a collective bargaining unit. Professional Bank considers relations with employees to be good.

Legal Proceedings

Professional Bank is periodically a party to or otherwise involved in legal proceedings arising in the normal course of business such as claims to enforce liens, claims involving the making and servicing of real property loans, and other issues incident to its business. Management does not believe that there is any pending or threatened proceeding against Professional Bank which, if determined adversely, would have a material adverse effect on Professional Bank’s financial position, liquidity, or results of operations.

Competition

Professional Bank encounters strong competition both in making loans and in attracting deposits. The deregulation of the banking industry and the widespread enactment of state laws which permit multi-bank holding companies as well as an increasing level of interstate banking have created a highly competitive environment for commercial banking. In one or more aspects of its business, Professional Bank competes with other commercial banks, savings and loan associations, credit unions, finance companies, mutual funds, insurance companies, brokerage and investment banking companies, and other financial intermediaries. Most of these competitors, some of which are affiliated with bank holding companies, have substantially greater resources and lending limits, and may offer certain services that Professional Bank does not currently provide. In addition, many of Professional Bank’s non-bank competitors are not subject to the same extensive federal regulations that govern bank holding companies and federally insured banks. Recent federal and state legislation has heightened the competitive environment in which financial institutions must conduct their business, and the potential for competition among financial institutions of all types has increased significantly. There is no assurance that increased competition from other financial institutions will not have an adverse effect on Professional Bank’s operations.

Management

Directors.   The Professional board of directors is comprised of 10 individuals and the Professional Bank board of directors is comprised of 10 individuals. The Professional and Professional Bank boards are each 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.

BENEFICIAL OWNERSHIP OF PROFESSIONAL COMMON STOCK BY MANAGEMENT AND PRINCIPAL SHAREHOLDERS OF PROFESSIONAL

BENEFICIAL OWNERS

The following table sets forth information as of April 1, 2022, regarding the beneficial ownership of Professional common stock by:

•

each person or group known by Professional to beneficially owns more than 5% of Professional outstanding shares of common stock;

•

each of Professional’s NEOs;

•

each of Professional’s directors; and

•

all of Professional’s current executive officers and directors as a group.

Professional has determined beneficial ownership in accordance with the rules of the SEC. These rules generally provide that a person is the beneficial owner of securities if such person has or shares the power to vote or direct the voting of securities, or to dispose or direct the disposition of securities, or has the right to acquire such powers within 60 days through (i) the exercise of any option, warrant or right, (ii) the conversion of a security, (iii) the power to revoke a trust, discretionary account or similar arrangement or (iv) the automatic termination of a trust, discretionary account or similar arrangement. For purposes of calculating each person’s percentage ownership, common stock issuable pursuant to stock options that are currently exercisable or will become exercisable within 60 days are included as outstanding and beneficially owned for that person or group, but are not deemed outstanding for the purposes of computing the percentage ownership of any other person. Except as disclosed in the footnotes to this table and subject to applicable community property laws, Professional believes that each person identified in the table has sole voting and investment power over all of the shares shown opposite such person’s name.

The percentage of beneficial ownership is based on 13,665,801 shares of Professional Class A Common Stock outstanding as of April 1, 2022.

Unless otherwise indicated in the table below, the address for each beneficial owner is c/o Professional Holding Corp., 396 Alhambra Circle, Suite 255, Coral Gables, Florida 33134.

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 FBCA 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

108

benefits to our shareholders. These provisions are more fully described in the documents and reports filed 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 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.

109

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

110

removed only for cause and only upon the affirmative vote at a meeting duly called and held for that purpose 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 Professional by SBC pursuant to the merger of Professional with and into SBC (the “Merger”) and the merger of the Bank with and into SNB (the “Bank Merger”) pursuant to the terms of the Plan of Merger and Merger Agreement between SNB and the Bank attached hereto as Exhibit A (the “Bank Merger Agreement”); and

The Merger shall take effect when the Articles of Merger become effective (the “Effective Time”). Subject to the terms and conditions hereof, the Parties shall use their reasonable best efforts to cause the Effective Time to occur on or before February 28, 2023; provided that, if such date is not practicable, the parties shall cause the Effective Time to occur on a mutually agreeable date within ten (10) Business Days following the date on which satisfaction or waiver of the conditions set forth in Article 5 has occurred (other than those conditions that by their nature are to be satisfied at the Closing, but subject to the fulfillment or waiver of those conditions).

1.5   Conversion of Professional Common Stock.

(a)   At the Effective Time, in each case subject to Section 1.5(d) and excluding Dissenting 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 Professional 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 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 (the “Merger Consideration Adjustment”) calculated in accordance with Schedule 1.5(a) of the Seacoast Disclosure Letter, and waive the satisfaction of such condition set forth in Section 5.2(j). If instead of adjusting the Merger Consideration, Seacoast elects not to close the Merger transaction and terminate this Agreement in accordance with Article 6 hereof, Seacoast agrees that it will also waive any breach of Section 4.2(v). At least ten (10) days prior to the Closing Date, the Company and Seacoast shall agree on a schedule setting forth the expected Professional Consolidated Tangible Shareholders’ Equity amount as of the Closing Date.

(c)   Notwithstanding any other provision of this Agreement, each holder of shares of Professional Common Stock or Professional Restricted Stock Awards 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 Professional 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 Average 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 Professional 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 Professional 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 Professional Common Stock held on behalf of third parties) shall, by virtue of the Merger and

(b)   Treatment of Professional Restricted Stock Awards.   At the Effective Time, each share of Professional Common Stock that is subject to a Professional Restricted Stock Award that is outstanding immediately prior to the Effective Time shall, by virtue of the Merger, automatically be vested and converted into the right to receive, subject to the terms herein, the Merger Consideration pursuant to Section 1.5, subject to withholding pursuant to Section 2.1(c).

(c)   Treatment of Professional Stock Appreciation Rights.   Immediately prior to the Effective Time, Professional shall cause each Professional Stock Appreciation Right that is outstanding immediately prior to the Effective Time to be vested and exercised for a number of shares of Professional Common Stock determined pursuant to the terms of the applicable Stock Appreciation Right award agreement, subject to applicable withholding. At the Effective Time, each share of Professional Common Stock issuable as a result of such exercise of Professional Stock Appreciation Rights shall, by virtue of the Merger, automatically be vested and converted into the right to receive, subject to the terms herein, the Merger Consideration pursuant to Section 1.5.

(d)   No Professional Equity Award shall be outstanding as of the Effective Time, and no obligations to issue Professional Equity Awards shall exist following the Effective Time. Prior to the Effective Time, the Company shall take all actions necessary (including delivering all required notices and obtaining all necessary approvals and consents) to effect the treatment of the Professional Equity Awards as provided in this Section 1.7, to terminate the Professional Stock Plans as of the Effective Time, and to cause the provisions of any other 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, and the Company shall ensure that following the Effective Time no person who was, immediately prior to the Effective Time, a holder of any Professional Equity Award, a person for whom a future grant of a Professional Equity Award had been approved, or a participant in any Professional Stock Plan or other Benefit Plan, shall have any right thereunder to acquire any capital stock of SBC, SNB, or the Company, except with respect to Substitute SBC Options, or as provided in Section 1.5 of this Agreement with respect to the Professional Common Stock which such person received or became entitled to receive in accordance with the exercise of such Professional Equity Award prior to the Effective Time.

1.9   Tax Consequences.   It is the intention of the Parties to this Agreement that the Merger and the Bank Merger, for federal income tax purposes, shall each qualify as a “reorganization” within the meaning of Section 368(a) of the Code and that this Agreement shall constitute a “plan of reorganization” for purposes of Sections 354 and 361 of the Code. The business purpose of the Merger and the Bank Merger is to combine two financial institutions to create a strong commercial banking franchise. SBC shall have the right to revise the structure of the Merger and/or the Bank Merger contemplated by this Agreement to ensure that the Merger and the Bank Merger each qualify as a “reorganization” within the meaning of Section 368(a) of the Code or to substitute an interim corporation that is wholly owned by SBC, which interim corporation may merge with and into Professional; provided, that no such revision to the structure of the Merger or the Bank Merger shall (a) result in any changes in the amount or type of the consideration that the holders of shares of Professional Common Stock are entitled to receive under this Agreement, (b) adversely affect the tax treatment of the Merger and/or the Bank Merger with respect to Professional shareholders as a result of the transactions contemplated by this Agreement, (c) reasonably be expected to materially impede or delay consummation of the Merger, or (d) require submission to or approval of Professional’s shareholders after this Agreement has been approved by Professional’s shareholders. SBC may exercise this right of revision by giving written notice to Professional in the manner provided in Section 7.9, which notice shall be in the form of an amendment to this Agreement.

ARTICLE 2
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 1.5(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 any 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 Professional Common Stock, including holders of the Professional Equity Awards who received Professional Common Stock in accordance with the exercise of such Professional 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 Professional Certificates for the Merger Consideration (which shall specify that delivery shall be effected, and risk of loss and title to the Professional Certificates shall pass, only upon proper delivery of such Professional 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 Professional 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 Professional Certificate shall be entitled to receive in exchange therefor the Merger Consideration in respect of the shares of Professional Common Stock represented by its Professional 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 Professional Certificate so surrendered is registered, it shall be a condition to such payment that such Professional Certificate shall be properly endorsed or otherwise be in proper form for transfer, and the

A-4

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 Professional 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 FBCA.

(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 Professional Common Stock such amounts as the Exchange Agent or SBC, as the case may be, is required to deduct and withhold under the Code or any other provision of applicable 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 Professional 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 Professional 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 Professional Certificates, without any interest thereon. Notwithstanding the foregoing, neither SBC nor the Exchange Agent shall be liable to any holder of a Professional 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 Professional Certificates.   In the event any Professional Certificates shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Professional 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 Professional Certificate(s), the Exchange Agent will issue the Merger Consideration deliverable in respect of the shares of Professional Common Stock represented by such lost, stolen or destroyed Professional Certificates.

2.2   Rights of Former Professional Shareholders.   On or before the Closing Date, the stock transfer books of Professional shall be closed as to holders of Professional Common Stock and no transfer of Professional 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 Professional Certificate (other than the Professional 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 certificate in accordance with Section 1.5(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 Professional 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 1.5(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 Professional Certificate in accordance with this Article 2. Subject to the effect of applicable abandoned property, escheat or similar laws, following surrender of any such Professional Certificate there shall 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 1.5(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

A-5

pursuant to Section 1.5(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 provisions of Section 607.1301 through 607.1340 of the FBCA (the “Dissenter Provisions”). Each Dissenting Shareholder shall be entitled to receive only the payment provided by the Dissenter Provisions with respect to shares of Professional 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 Dissenter Provisions. 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.

No attorney representing Professional or any Subsidiary, whether or not employed by Professional or any Subsidiary, has

A-10

reported evidence of a material violation (as such term is interpreted under Section 307 of the Sarbanes-Oxley Act of 2002, as amended, and the rules and regulations promulgated thereunder (the “Sarbanes-Oxley Act”)) of securities laws, breach of fiduciary duty or similar violations by Professional or any Subsidiary or any officers, directors, employees or agents of Professional or any of its Subsidiaries or any committee thereof or to any director or officer of Professional.

(v)   Professional’s independent public accountants, which have expressed their opinion with respect to the Professional Financial Statements (including the related notes), are and have been throughout the periods covered by such Financial Statements (A) a registered public accounting firm (as defined in Section 2(a)(12) of the Sarbanes-Oxley Act) (to the extent applicable during such period), (B) “independent” with respect to Professional within the meaning of Regulation S-X and (C) with respect to Professional, in compliance with subsections (g) through (l) of Section 10A of the 1934 Act and related Securities Laws.

Other than as set forth in the Professional SEC Reports, since December 31, 2019, there have been no significant changes in internal controls or in other factors that could significantly affect internal controls of Professional. There is no reason to believe that Professional’s outside auditors and its Chief Executive Officer and Chief Financial Officer will not be able to give the certifications and attestations required pursuant to the rules and regulations adopted pursuant to Section 404 of the Sarbanes-Oxley Act, without qualification, when next due.

No claim has ever been made by a Taxing Authority in a jurisdiction where Professional or any of its Subsidiaries does not file a Tax Return that Professional or any of its Subsidiaries is or may be subject to Taxes by that jurisdiction, and to the Knowledge of Professional and each of its Subsidiaries, no basis for such a claim exists.

(ii)   Neither Professional nor any of its Subsidiaries has received any notice of assessment or proposed assessment in connection with any amount of Tax, and there is no threatened or pending dispute, action, suit, proceeding, claim, investigation, audit, examination, or other Litigation regarding any Tax of Professional and any of its Subsidiaries or the assets of Professional and its Subsidiaries.

Each Party shall file any application and notice required of it to any Regulatory Authority within sixty (60) days following the date of this Agreement.

(c)   Each Party will promptly furnish to the other Party 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 hereby.

Professional shall deliver to Seacoast a copy of each written opinion (or any withdrawal of such opinion) of Stephens Inc. or any other financial advisor, as soon as reasonably practicable after the Company’s receipt thereof.

A-33

4.10   Investigation and Confidentiality.

(a)   Upon reasonable notice and subject to applicable Laws, each Party shall permit the other to make or cause to be made such investigations of the business and Properties of it and its Subsidiaries and of its Subsidiaries’ financial and legal conditions as the other reasonably requests; provided, that such investigation shall be reasonably related to the transactions contemplated hereby and shall not interfere unnecessarily with normal operations. No investigation by a Party shall affect the representations and warranties of the other or the right of a Party to rely thereon. Neither Party shall be required to provide access to or to disclose information where such access or disclosure would jeopardize the attorney-client privilege of Professional (after giving due consideration to the existence of any common interest, joint defense or similar agreement between the Parties) or contravene any Law or binding agreement entered into prior to the date of this Agreement. The Parties will make appropriate substitute disclosure arrangements under circumstances in which the restrictions of the preceding sentence apply.

(b)   Each Party shall, and shall cause its directors, officers, employees and Representatives to, maintain the confidentiality of all confidential information furnished to it by the other Party concerning its and its Subsidiaries’ businesses, operations, and financial positions to the extent required by, and in accordance with, the Confidentiality Agreement, and shall not use such information for any purpose except in furtherance of the transactions contemplated by this Agreement. No investigation by either Party shall affect the representations and warranties of the other Party or the right of such investigating Party to rely thereon.

4.11   Press Releases; Publicity.   Prior to the Effective Time, Seacoast shall provide Professional with a draft of any press release, other public statement or shareholder communication related to this Agreement and the transactions contemplated hereby prior to issuing such press release, public statement or shareholder communication or making any other public or shareholder disclosure related thereto, and Seacoast shall consider any comments and/or modifications to any such press release or public statement provided by Professional; provided, that nothing in this Section 4.11 shall be deemed to prohibit any Party from making any disclosure that its counsel deems necessary or advisable in order to satisfy such Party’s disclosure obligations imposed by Law, SEC or NASDAQ.

4.12   Acquisition Proposals.

(a)   Professional agrees that it will not, and will cause its directors, officers, employees and Representatives and Affiliates not to, (i) initiate, solicit, or knowingly encourage or 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 relating to, any Acquisition Proposal; provided, that, in the event Professional receives an unsolicited bona fide Acquisition Proposal that does not violate (i) and (ii) above at any time prior to, but not after, the time this Agreement is adopted by the Professional Shareholder Approval, and Professional’s Board of Directors concludes in good faith that there is a reasonable likelihood that such Acquisition Proposal constitutes or is reasonably likely to result in a Superior Proposal, Professional may, and may permit its officers and Representatives to, furnish or cause to be furnished nonpublic information or data and participate in such negotiations or discussions to the extent that the Board of Directors of Professional concludes in good faith (and based on the written advice of outside legal counsel) that failure to take such actions would reasonably be expected to result in a breach of its fiduciary obligations to the Professional Shareholders under applicable Law; provided further, that prior to providing any nonpublic information permitted to be provided pursuant to the foregoing proviso, Professional shall have entered into a confidentiality agreement with such third party on terms no less favorable to it than the Confidentiality Agreement. Professional will immediately cease and cause to be terminated any activities, discussions or negotiations conducted before the date of this Agreement with any Persons other than Seacoast with respect to any Acquisition Proposal. Professional shall promptly (and in any event within two Business Days) advise Seacoast following the receipt or notice of any Acquisition Proposal and the substance thereof (including the identity of the Person making such Acquisition Proposal), and will keep Seacoast apprised of any related developments, discussions and negotiations on a current basis. Professional agrees that any breach by its Representatives of this Section 4.12 shall be deemed a breach by Professional.

A-34

(b)   Notwithstanding the foregoing, if Professional’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, Professional’s Board of Directors may at any time prior to the Professional Shareholder Approval (i) withdraw or modify (a “Change in Recommendation”) the Professional 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 Professional 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 Professional may not make a Change in Recommendation, and terminate this Agreement, with respect to an Acquisition Proposal unless (i) Professional shall not have breached this Section 4.12 in any respect and (ii) (A) the Board of Directors of Professional 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) Professional 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, Professional 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. In the event of any material change to the terms of such Superior Proposal, Professional shall, in each case, be required to deliver to SBC a new written notice, the notice period shall have recommenced and Professional shall be required to comply with its obligations under this Section 4.12 with respect to such new written notice. Professional will advise SBC in writing within twenty-four (24) hours following the receipt of any Acquisition Proposal and the substance thereof (including the identity of the Person making such Acquisition Proposal) and will keep SBC apprised of any related developments, discussions and negotiations (including the terms and conditions of the Acquisition Proposal) on a current basis.

4.13   Takeover Laws.   If any Takeover Law may become, or may purport to be, applicable to the transactions contemplated hereby, Professional and the members of its Board of Directors will grant such approvals and take such actions as are necessary (other than any action requiring the approval of its shareholders (other than as contemplated by Section 4.5)) so that the transactions contemplated by this Agreement may be consummated as promptly as practicable on the terms contemplated hereby and otherwise act to eliminate or minimize the effects of any Takeover Law on any of the transactions contemplated by this Agreement.

4.14   Employee Benefits and Contracts.

(a)   Following the Effective Time, SBC shall maintain or cause to be maintained employee benefit plans and compensation opportunities for the benefit of employees (as a group) who are full-time active employees of Professional and/or its subsidiaries on the Closing Date (“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 made available on a uniform and non-discriminatory basis to similarly situated employees of SBC or its Subsidiaries, as applicable; provided, however, that in no event shall any Covered Employee be eligible to participate in any closed or frozen plan of SBC or its Subsidiaries; and provided further that in no event shall SBC be required to take into account any retention arrangements or equity compensation when determining whether employee benefits are substantially comparable. SBC shall give the Covered Employees full credit for their prior service with Professional and its Subsidiaries (i) 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 SBC and in which Covered Employees may be eligible to participate and (ii) for all purposes under any welfare benefit plans, vacation plans and similar arrangements maintained by SBC.

A-35

(b)   With respect to any employee benefit plan of SBC that is a 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, SBC or its applicable Subsidiary shall use its commercially reasonable best efforts to (i) cause any pre-existing condition limitations or eligibility waiting periods under such SBC or Subsidiary plan to be waived with respect to such Covered Employee to the extent such condition was or would have been covered under the Professional Benefit Plan in which such Covered Employee participated immediately prior to the Effective Time, and (ii) recognize any health, dental, vision or other welfare expenses incurred by such Covered Employee in the year that includes the Closing Date (or, if later, the year in which such Covered Employee is first eligible to participate) for purposes of any applicable deductible and annual out-of-pocket expense requirements under any such health, dental, vision or other welfare plan.

(c)   Prior to the Effective Time, Professional shall take all actions requested by SBC that may be necessary or appropriate to (i) cause Professional’s 401(k) Plan, and one or more of the Professional Benefits Plans to terminate as of the Effective Time, or as of the date immediately preceding the Effective Time, (ii) cause benefit accruals and entitlements under any Professional Benefit Plan to cease as of the Effective Time, or as of the date immediately preceding the Effective Time, (iii) cause the continuation on and after the Effective Time of any contract, arrangement or insurance policy relating to any Professional Benefit Plan for such period as may be requested by SBC, or (iv) facilitate the merger of any Professional Benefit Plan into any employee benefit plan maintained by SBC or an SBC Subsidiary. All resolutions, notices, or other documents issued, adopted or executed in connection with the implementation of this Section 4.14(c) shall be subject to SBC’s reasonable prior review and approval, which shall not be unreasonably withheld, conditioned, or delayed.

(d)   Nothing in this Section 4.14 shall be construed to limit the right of SBC or any of its Subsidiaries (including, following the Closing Date, Professional) to amend or terminate any Professional Benefit Plan or other employee benefit plan, to the extent such amendment or termination is permitted by the terms of the applicable plan, nor shall anything in this Section 4.14 be construed to require SBC or any of its Subsidiaries (including, following the Closing Date, Professional) to retain the employment of any particular Covered Employee for any fixed period of time following the Closing Date, and the continued retention (or termination) by SBC or any of its Subsidiaries of any Covered Employee subsequent to the Effective Time shall be subject in all events to SBC’s or its applicable Subsidiary’s normal and customary employment procedures and practices, including customary background screening and evaluation procedures, and satisfactory employment performance.

(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 Professional), is terminated by SBC or its Subsidiaries other than (i) “for cause” or (ii) 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 Professional at the Closing). Any severance to which a Covered Employee may be entitled in connection with a termination occurring more than six (6) months after the Effective Time will be as set forth in the severance policies set forth in Section 4.14(e)(ii) of the Seacoast Disclosure Letter.

(f)   At or before the Closing, Professional shall make the payments set forth on Section 4.14(f) of the Company Disclosure Letter.

4.15   Indemnification.

(a)   From and after the Effective Time, in the event of any threatened or actual claim, action, suit, proceeding, or investigation, whether civil, criminal, or administrative, in which any Person who is now, or has been at any time prior to the date of this Agreement, or who becomes prior to the Effective Time, a director or officer of Professional or any of its Subsidiaries (each an “Indemnified Party”) is, or is threatened to be, made a party based in whole or in part on, or arising in whole or in part out of, or pertaining to (i) the fact that the Indemnified Party is or was a director, officer, or employee of Professional, its Subsidiaries or any of its predecessors, or (ii) this Agreement or any of the transactions contemplated hereby, whether in any case asserted or arising before or after the Effective Time, Seacoast shall indemnify, defend and hold harmless to the same extent such Indemnified Parties have the right to be indemnified and/or

A-36

have the right to advancement of expenses pursuant to (x) the Organizational Documents of Professional or such Subsidiary, as applicable and (y) the FBCA or other applicable Law, each such Indemnified Party against any Liability (including advancement of reasonable attorneys’ fees and expenses prior to the final disposition of any claim, suit, proceeding, or investigation to each Indemnified Party to the fullest extent permitted by Law upon receipt of any undertaking required by applicable Law), judgments, fines, and amounts paid in settlement in connection with any such threatened or actual claim, action, suit, proceeding, or investigation. In the event of any such threatened or actual claim, action, suit, proceeding, or investigation (whether asserted or arising before or after the Effective Time), the Indemnified Parties may retain counsel reasonably satisfactory to them; provided, that (1) Seacoast shall have the right to assume the defense thereof and upon such assumption Seacoast shall not be required to advance to any Indemnified Party any legal expenses of other counsel or any other expenses subsequently incurred by any Indemnified Party in connection with the defense thereof, except that if Seacoast elects not to assume such defense or counsel for the Indemnified Parties reasonably advises the Indemnified Parties that there are material issues that raise conflicts of interest between Seacoast and the Indemnified Parties, the Indemnified Parties may retain counsel reasonably satisfactory to them, and Seacoast shall advance the reasonable fees and expenses of such counsel for the Indemnified Parties, (2) Seacoast shall not be liable for any settlement effected without its prior written consent (which consent shall not be unreasonably withheld), and (3) Seacoast shall have no further obligation hereunder to any Indemnified Party when and if a court of competent jurisdiction shall determine, and such determination shall have become final, that indemnification of such Indemnified Party in the manner contemplated hereby is prohibited by applicable Law.

(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 Professional and the Bank 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 Professional or the Bank, 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 Professional or the Bank at or before the Effective Time to be covered by Professional’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 such coverage exceed 150% of the current annual premium paid by Professional (such amount, as set forth on Section 4.15(c) of the Company Disclosure Letter) for such insurance. Such insurance coverage shall commence at the Effective Time and will be provided for a period of no less than six (6) years after the Effective Time.

(d)   If SBC or SNB or any of their respective successors or assigns shall consolidate with or merge into any other Person and shall not be the continuing or surviving Person of such consolidation or merger or shall transfer all or substantially all of its assets to any Person, then and in each case, proper provision shall be made so that the successors and assigns of SBC or SNB, as applicable, as the surviving entities shall assume the obligations set forth in this Section 4.15.

(e)   The provisions of this Section 4.15 are intended to be for the benefit of and shall be enforceable by, each Indemnified Party and his or her heirs and representatives.

4.16.   Resolution of Certain Matters.   Professional shall use its reasonable best efforts and take any and all actions (including completing any necessary filings with Regulatory Authorities) to resolve the items set forth on Section 4.16 of the Seacoast Disclosure Letter, all subject to SBC’s reasonable satisfaction.

4.17   Claims Letters.   Concurrently with the execution and delivery of this Agreement and effective upon the Closing, Professional has caused each director of Professional and the Bank or officer of the Company or the Bank set forth on Section 4.17 of the Seacoast Disclosure Letter to execute and deliver a Claims Letter in the form attached hereto as Exhibit C.

Following the date hereof, Professional shall provide Seacoast access to the Bank’s data files to facilitate the conversion process, including but not limited to, (i) sample data files with data dictionary no later than 30 days following the date of this Agreement; (ii) a full set of data files, including electronic banking and online bill payment data, for mapping and mock conversion no later than 180 days prior to the targeted conversion date as determined by Seacoast; (iii) a second full set of data files from which to establish CIS records, deposit shells, electronic banking accounts, bill payment payees and order debit cards no later than 45 days prior to the targeted conversion date; and (iv) a final set of data files no later than the date of the targeted conversion date. Professional shall coordinate and participate in regular meetings between data processing vendors and Seacoast representatives, to begin within 30 days following the date of this agreement, to facilitate system integration. Professional shall cooperate with Seacoast in connection with the planning for the efficient and orderly combination of the parties and the operation of SNB (including the former operations of Professional) after the Merger and the Bank Merger, and in preparing for the consolidation of appropriate operating functions to be effective at the Effective Time or such later date as Seacoast may decide. Prior to the Effective Time, Professional shall take any action that Seacoast may reasonably request to facilitate the combination of the operations of the Bank with SNB and Professional shall allocate and apply resources and personnel with appropriate expertise and authority to effectuate such requests. Without limiting the foregoing, Professional shall provide office space and support services (and other reasonably requested support and assistance) in connection with the foregoing, and senior officers of Professional and Seacoast shall meet from time to time as Professional or Seacoast may reasonably request, to review the financial and operational affairs of Professional and its Subsidiaries, and Professional shall give due consideration to Seacoast’s input on such matters, with the understanding that, notwithstanding any other provision contained in this Agreement, (i) neither SBC nor SNB shall be permitted to exercise control of Professional or the Bank prior to the Effective Time, and (ii) neither Professional nor the Bank shall be under any obligation to act in a manner that could reasonably be deemed to constitute anti-competitive behavior under federal or state antitrust Laws. Professional shall be responsible for all conversion and deconversion fees and expenses, regardless of whether the Merger becomes effective.

4.20   Additional Contracts.   Effective at Closing Date, the parties shall have entered into the contracts and in the form set forth on Section 4.20 of the Seacoast Disclosure Letter.

4.21   Transfer Taxes.   All transfer, documentary, excise, sales, use, value added, registration, stamp, recording, property and other similar Taxes and fees (including any penalties and interest) applicable to, imposed upon, or arising out of the transactions contemplated by this Agreement or the Bank Merger Agreement (collectively, “Transfer Taxes”) shall be paid by Professional shareholders when due. The Professional shareholders will timely file or cause to be timely filed all necessary documentation and Tax Returns with respect to Transfer Taxes, and Seacoast will assist in such filing as may be required by applicable Law. Each Party will each use its commercially reasonable efforts to avail itself of any available exemptions from any such Transfer Taxes.

4.22   280G Payments.   To the extent any payments or benefits made with respect to, or which could arise as a result of, this Agreement or the transactions contemplated hereby, could be characterized as an “excess parachute payment” within the meaning of Section 280G(b)(1) of the Internal Revenue Code,

A-38

Professional shall, prior to the Closing Date, cooperate in good faith with Seacoast to effect reasonable measures to minimize any such payments or benefits from being characterized as “excess parachute payments” within the meaning of Section 280G(b)(1) of the Internal Revenue Code.

4.23   SBC Advisory Board.   SBC shall form an advisory board with respect to the Bank’s current market area and shall extend an invitation to each member of the Professional board of directors immediately prior to the Effective Time to serve on such advisory board, provided, however, that such directors have each entered into a Claims Letter and Restrictive Covenant Agreement pursuant to Section 4.17 and Section 4.18 hereto, respectively.

4.24   Assumption of Professional Subordinated Notes.

(a)   Professional shall, and shall cause its respective Subsidiaries and shall use commercially reasonable efforts to cause its and their Representatives to, take all actions necessary, appropriate or advisable to facilitate and cause SBC to assume all issued and outstanding 3.375% fixed-to-floating rate subordinated notes due January 30, 2032 of Professional (the “Subordinated Notes”), effective as of, and subject to and conditioned upon the occurrence of, the Closing, in accordance with the Subordinated Notes and such other governing instruments and applicable law.

(b)   In furtherance and not in limitation of the foregoing, prior to and at the Closing, Professional shall, and shall cause its Subsidiaries and shall use commercially reasonable efforts to cause its and their Representatives to, take such actions as may be necessary, appropriate or advisable in connection with the assignment and assumption of the Subordinated Notes by SBC and cooperate and take all such action as may be reasonably requested by Seacoast in connection therewith, including by (i) preparing and delivering notices of assignment, in form and substance reasonably satisfactory to Seacoast, in accordance with the Subordinated Notes and other governing documents, and (ii) executing and delivering all instruments, including any related certificates, opinions or other documentation, reasonably required in connection with SBC’s assumption of the Subordinated Notes at Closing.

(a)   The Shareholder has voting power over the number of shares (“Shareholder’s Shares”) of the Class A common stock of Seller, par value $0.01 per share (“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.

(b)   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.

(c)   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.

(d)   The Shareholder’s Shares and any 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.

(e)   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 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.

A-61

(f)   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.

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

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

(a)   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.

(b)   At any Shareholders’ Meeting or in any other circumstances upon which a Seller shareholder 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.

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

(a)   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 Shareholder’s Shares set forth in this Section 3(a) shall terminate upon the first to occur

A-62

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.

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

(c)   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.

4.   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.

5.   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.

6.   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.

A-63

7.   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.

8.   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, product/service formulas, pricing, mark-ups, commissions, information concerning techniques for use and integration of websites and other products/​services, current and future development and expansion or contraction plans, sale/acquisition plans and contacts, marketing plans and contacts, information concerning the legal affairs of and information concerning the pricing of products and services, strategy, tactics and financial affairs 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.

9.   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.

10.   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.

11.   Miscellaneous.

(a)   Capitalized terms used and not otherwise defined in this Agreement shall have the respective meanings assigned to them in the Merger Agreement. As used herein, the singular shall include the plural and any reference to gender shall include all other genders.

The undersigned represents, warrants and covenants that no Claim released, discharged, transferred or assigned herein has been transferred, sold or assigned, expressly, impliedly, by operation of law or otherwise, and that all Claims released, discharged, transferred or assigned hereby are owned solely and exclusively by the undersigned, which has the sole authority to release, discharge, transfer and assign them to Buyer, as the successor to Seller.

RESTRICTIVE COVENANT AGREEMENT
(EXECUTIVE OFFICER)

THIS RESTRICTIVE COVENANT AGREEMENT (the “Agreement”) is made and entered into as of [•], 2022, by and between Seacoast Banking Corporation of Florida, a Florida corporation (“Buyer”), and the undersigned executive officer (“Employee”) of Professional Holding Corp., a Florida corporation (“Professional”) and/or Professional Bank, a Florida state-chartered bank and wholly owned subsidiary of Professional (the “Bank” and collectively with Professional, “Seller”) and shall become effective as of the Effective Time of the Merger as provided in the Merger Agreement (defined below).

WHEREAS, Buyer, Seacoast National Bank, a national banking association and wholly owned subsidiary of Buyer (“SNB”), Professional and the Bank are parties to that certain Agreement and Plan of Merger, dated as of [•], 2022, as the same may be amended or supplemented (the “Merger Agreement”), that provides for, among other things, the merger of Professional with and into Buyer (the “Merger”), and the subsequent merger of the Bank with and into SNB (the “Bank Merger”);

WHEREAS, Employee is a shareholder of Professional and/or officer of Professional and/or the Bank;

WHEREAS, as a result of the Merger and pursuant to the transactions contemplated by the Merger Agreement, Employee and/or an Affiliate of Employee is selling shares of Professional Common Stock held by Employee and/or the Employee’s Affiliate to Buyer and will receive Merger Consideration from Buyer in exchange for such shares;

WHEREAS, Employee is in possession of trade secrets and valuable confidential business information of Seller, and has substantial relationships with its banking customers;

WHEREAS, prior to the date hereof, Employee has served as a manager of Seller, and, therefore, Employee has knowledge of the Confidential Information (hereinafter defined) and/or relationships with the Seller’s executives, customers, and customer goodwill;

WHEREAS, the Employee acknowledges that the Buyer has legitimate business interests to justify the enforcement of this Agreement;

WHEREAS, as a result of the Merger and the Bank Merger, Buyer will acquire substantial customer relationships from Seller and succeed to all of the Confidential Information, for which Buyer, as of the Effective Time, will have paid valuable consideration and desires reasonable protection; and

WHEREAS, the Merger Agreement contemplates that, upon the execution and delivery of the Merger Agreement by Seller, as a condition and inducement to the willingness of Buyer and SNB to enter into the Merger Agreement, Employee will enter into and perform this Agreement.

NOW THEREFORE, in consideration of the premises and for other good and valuable consideration, including, without limitation, the Merger Consideration to be received by Employee and/or the Employee’s Affiliate, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, intending to be legally bound, covenant and agree as follows:

1.   Certain Definitions.

(a)   “Affiliated Company” means any company or entity controlled by, controlling or under common control with Buyer or Seller.

(b)   “Confidential Information” means all information regarding Seller, Buyer, SNB and their respective Affiliated Companies and any of their respective activities, businesses or customers that is not generally known to persons not employed by Seller, Buyer, SNB or their respective Affiliated Companies, and that is not generally disclosed publicly to persons not employed by Seller, Buyer, SNB or their respective Affiliated Companies (except to applicable regulatory authorities and/or pursuant to confidential or other relationships where there is no expectation of public disclosure or use by third Persons). “Confidential Information” shall include, without limitation, all customer information,

A-72

customer identity and customer lists, confidential methods of operation, lending and credit information, banking and financial information about customers and employees, commissions, mark-ups, product/​service formulas, information concerning techniques for use and integration of websites and other products/services, proprietary computer systems and databases (and their contents) such as the Bank’s RPS system, current and future development and expansion or contraction plans of Seller, Buyer, SNB, or their respective Affiliated Companies, sale/acquisition plans and contacts, marketing plans and contacts, information concerning the legal affairs of and information concerning the pricing of products and services, strategy, tactics and financial affairs of Seller, Buyer, SNB, or their respective Affiliated Companies. “Confidential Information” also includes any “confidential information,” “trade secrets,” or any equivalent term under any applicable federal, state, or local law. “Confidential Information” shall not include information that (i) has become generally available to the public by the act of one who has the right to disclose such information without violating any right or privilege of Seller, Buyer or SNB or their respective Affiliated Companies or any duty owed to any of them; or (ii) is independently developed by a person or entity without reference to or use of Confidential Information. Employee acknowledges and agrees that the trading in Buyer or Seller securities using Confidential Information or other non-public information may violate federal and state securities laws.

(c)   Capitalized terms used but not defined herein shall have the same meanings provided in the Merger Agreement.

2.   Restrictive Covenants.

(a)   Nondisclosure of Confidential Information.   From the Effective Time and thereafter for so long as such information remains Confidential Information, Employee 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. Anything herein to the contrary notwithstanding, Employee shall not be restricted from disclosing information that is required to be disclosed by law, court order or other valid and appropriate legal process; provided, however, that in the event such disclosure is required by law, Employee shall (i) if allowed by law or legal process, provide Buyer with prompt notice of such requirement so that Buyer may seek an appropriate protective order prior to any such required disclosure by Employee; and (ii) use commercially reasonable efforts to obtain assurances that any Confidential Information disclosed will be accorded confidential treatment; provided, further, that no such notice or efforts shall be required in connection with any routine audit or investigation by any Governmental Authority or taxing authority that does not expressly reference Seller, Buyer, SNB or any of their respective Affiliated Companies. If, in the absence of a required waiver or protective order, Employee is nonetheless, in the good faith written opinion of his legal counsel, required to disclose Confidential Information, disclosure may be made only as to that portion of the Confidential Information that counsel advises Employee is required to be disclosed.

(b)   Nonrecruitment of Employees.   Employee hereby agrees that, for two (2) years following the Effective Time or for two (2) years following Employee’s affiliation with Buyer or SNB as an officer, employee, or consultant (whichever period is longer), Employee shall not, without the prior written consent of the Buyer’s Chief Executive Officer, which consent may be withheld at the sole discretion of the Buyer’s Chief Executive Officer, directly or indirectly solicit or recruit or attempt to solicit or recruit for employment or encourage to leave employment with Buyer or any of its Affiliated Companies, on his or her own behalf or on behalf of any other Person, (i) any then-current employee of Buyer or any of its Affiliated Companies or (ii) any employee of Seller who worked at Seller or any of its Affiliated Companies during Employee’s services as a manager of Seller or any Seller Affiliated Company and who has not ceased employment for a minimum of a six month period with Buyer, Seller, or any Affiliated Companies, as applicable. It is acknowledged that general advertisements shall not be deemed to violate this provision.

(c)   Nonsolicitation of Customers.   Employee hereby agrees that, for two (2) years following the Effective Time or for two (2) years following Employee’s affiliation with Buyer or SNB as an officer, employee, or consultant (whichever period is longer), Employee shall not, without the prior written consent of the Buyer’s Chief Executive Officer, which consent may be withheld at the sole discretion of

A-73

Buyer’s Chief Executive Officer, directly or indirectly, on behalf of himself, herself or of anyone other than Seller, Buyer, SNB or any Affiliated Company, in the Restricted Area (as defined in Section 2(d) below), solicit or attempt to solicit any customer or client of Seller for the purpose of either (i) providing any Business Activities (as defined in Section 2(d)) or (ii) inducing such customer or client to cease, reduce, restrict or divert its business with Seller, Buyer, SNB or any Affiliated Company. It is acknowledged that general advertisements shall not be deemed to violate this provision.

(d)   Noncompetition.   Employee hereby agrees that, for two (2) years following the Effective Time or for two (2) years following Employee’s affiliation with Buyer or SNB as an officer, employee, or consultant (whichever period is longer), Employee shall not Compete (as defined herein) against Buyer, SNB, or any of their Affiliated Companies in the Restricted Area without the prior written consent of Buyer’s Chief Executive Officer, which consent may be withheld at the sole discretion of Buyer’s Chief Executive Officer. For purposes of this Agreement, “Compete” means to engage or participate 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. For purposes of this Agreement, “Business Activities” shall be any business activities conducted by Buyer, Seller, SNB, or any of their Affiliated Companies, which includes 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. For purposes of this Agreement, the “Restricted Area” means each and any county where the Buyer, SNB, Bank or any of their Affiliated Companies (i) operates a banking office, or (ii) has operated a banking office within the preceding 12 months, or (iii) is actively engaged in providing Business Activities to customers. Nothing in this Section 2(d) shall prohibit Employee from acquiring or holding, for investment purposes only, less than five percent (5%) of the outstanding securities of any company or business organization which may compete directly or indirectly with Seller, Buyer, SNB or any of their Affiliated Companies. Nothing in this Agreement shall prohibit Employee or any of such Employee’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 Employee or any of such Employee’s Affiliated Company as of the date of this Agreement.

(e)   Enforceability of Covenants.   Employee 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. Employee 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. Employee acknowledges that the term, geographic area, and scope of the covenants set forth in this Agreement are reasonable, and agrees that he 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. Employee agrees that his position as an Employee of Professional and/or the Bank involves duties and authority relating to all aspects of the Business Activities and all of the Restricted Area. Employee further acknowledges that complying with the provisions contained in this Agreement will not preclude him from engaging in a lawful profession, trade or business, or from becoming gainfully employed. Employee and Buyer agree that Employee’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 provision of this Agreement shall not constitute a defense to the enforceability of this covenant. 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. Employee hereby agrees that, in addition to all other remedies provided at law or in equity,

A-74

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 Employee), and to exercise all other rights or remedies, at law or in equity, including, without limitation, the rights to damages.

3.   Successors.

(a)   This Agreement is personal to Employee, is not assignable by Employee, and none of Employee’s duties hereunder may be delegated.

(b)   This Agreement may be assigned by, and shall be binding upon and inure to the benefit of the Buyer, SNB and any of their Affiliated Companies and their successors and assigns.

4.   Miscellaneous.

(a)   Waiver.   No provision of this Agreement may be modified, waived or discharged unless such waiver, modification or discharge is agreed to in writing signed by Employee and Buyer. 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.

(b)   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.

(c)   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.

(d)   Governing Law and Forum Selection.   Buyer and Employee agree that this Agreement shall be governed by and construed and interpreted in accordance with the laws of the State of Florida without giving effect to its conflicts of law principles, and that any and all disputes arising out of or relating to this Agreement shall be brought and exclusively maintained in the 19th Circuit Court in and for Martin County, Florida, Stuart Division. With respect to any such court action, Employee 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.

(e)   Notices.   All notice, consent, demand, request or other communication given to a party hereto in connection with this Agreement shall be in writing and shall be deemed to have been given such party (i) when delivered personally to such party or (ii) provided that a written acknowledgement of receipt is obtained, five (5) days after being sent by prepaid certified or registered mail or two (2) days after being sent by a nationally recognized overnight courier, to the address (if any) specified below for such party (or to such other address that such party shall have specified by ten (10) days’ advance notice given in accordance with this Section 4(e)).

EXHIBIT D-2​

RESTRICTIVE COVENANT AGREEMENT
(DIRECTOR)

THIS RESTRICTIVE COVENANT AGREEMENT (the “Agreement”) is made and entered into as of [•], 2022, by and between Seacoast Banking Corporation of Florida, a Florida corporation (“Buyer”), and the undersigned director (“Director”) of Professional Holding Corp., a Florida corporation (“Professional”) and/or Professional Bank, a Florida state-chartered bank and wholly owned subsidiary of Professional (the “Bank” and collectively with Professional, “Seller”) and shall become effective as of the Effective Time of the Merger as provided in the Merger Agreement (defined below).

WHEREAS, Buyer, Seacoast National Bank, a national banking association and wholly owned subsidiary of Buyer (“SNB”), Professional and the Bank are parties to that certain Agreement and Plan of Merger, dated as of [•], 2022, as the same may be amended or supplemented (the “Merger Agreement”), that provides for, among other things, the merger of Professional with and into Buyer (the “Merger”), and the subsequent merger of the Bank with and into SNB (the “Bank Merger”);

WHEREAS, as a result of the Merger and pursuant to the transactions contemplated by the Merger Agreement, Director acknowledges and agrees that he or she will derive significant financial and/or other benefits from the consummation of the transactions contemplated by the Merger Agreement;

WHEREAS, prior to the date hereof, Director has served as a member of the Board of Directors of Seller, and, therefore, Director has knowledge of the Confidential Information (hereinafter defined), has substantial relationships with the Seller’s executives, customers, and customer goodwill, and/or is in possession of trade secrets and valuable confidential business information of Seller;

WHEREAS, the Director acknowledges that the Buyer has legitimate business interests to justify the enforcement of this Agreement;

WHEREAS, as a result of the Merger and the Bank Merger, Buyer will acquire substantial customer relationships from Seller and succeed to all of the Confidential Information, for which Buyer, as of the Effective Time, will have paid valuable consideration and desires reasonable protection; and

WHEREAS, the Merger Agreement contemplates that, upon the execution and delivery of the Merger Agreement by Seller, as a condition and inducement to the willingness of Buyer and SNB to enter into the Merger Agreement, Director will enter into and perform this Agreement.

NOW THEREFORE, in consideration of the premises and for other good and valuable consideration, including, without limitation, the Merger Consideration to be received by Director and/or the Director’s Affiliate, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, intending to be legally bound, covenant and agree as follows:

1.   Certain Definitions.

(a)   “Affiliated Company” means any company or entity controlled by, controlling or under common control with Buyer or Seller.

(b)   “Confidential Information” means all information regarding Seller, Buyer, SNB and their respective Affiliated Companies and any of their respective activities, businesses or customers that is not generally known to persons not employed by Seller, Buyer, SNB or their respective Affiliated Companies, and that is not generally disclosed publicly to persons not employed by Seller, Buyer, SNB, or their respective Affiliated Companies (except to applicable regulatory authorities and/or pursuant to confidential or other relationships where there is no expectation of public disclosure or use by third Persons). “Confidential Information” shall include, without limitation, all customer information, customer identity and customer lists, confidential methods of operation, lending and credit information, banking and financial information about customers and employees, commissions, mark-ups, product/​service formulas, information concerning techniques for use and integration of websites and other products/services, proprietary computer systems and databases (and their contents) such as the Bank’s RPS system, current and future development and expansion or contraction plans of Seller, Buyer, SNB,

A-78

or their respective Affiliated Companies, sale/acquisition plans and contacts, marketing plans and contacts, information concerning the legal affairs of and information concerning the pricing of products and services, strategy, tactics and financial affairs of Seller, Buyer, SNB, or their respective Affiliated Companies. “Confidential Information” also includes any “confidential information,” “trade secrets,” or any equivalent term under any applicable federal, state, or local law. “Confidential Information” shall not include information that (i) has become generally available to the public by the act of one who has the right to disclose such information without violating any right or privilege of Seller, Buyer or SNB or their respective Affiliated Companies or any duty owed to any of them; or (ii) is independently developed by a person or entity without reference to or use of Confidential Information. Director acknowledges and agrees that the trading in Buyer or Seller securities using Confidential Information or other non-public information may violate federal and state securities laws.

2.   Restrictive Covenants.

(a)   Nondisclosure of Confidential Information.   For three (3) years after the Effective Time, 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. Anything herein to the contrary notwithstanding, Director shall not be restricted from disclosing information that is required to be disclosed by law, court order or other valid and appropriate legal process; provided, however, that in the event such disclosure is required by law, Director shall (i) if allowed by law or legal process, provide Buyer with prompt notice of such requirement so that Buyer may seek an appropriate protective order prior to any such required disclosure by Director; and (ii) use commercially reasonable efforts to obtain assurances that any Confidential Information disclosed will be accorded confidential treatment; provided, further, that no such notice or efforts shall be required in connection with any routine audit or investigation by any Governmental Authority or taxing authority that does not expressly reference Seller, Buyer, SNB or any of their respective Affiliated Companies. If, in the absence of a required waiver or protective order, Director is nonetheless, in the good faith written opinion of Director’s legal counsel, required to disclose Confidential Information, disclosure may be made only as to that portion of the Confidential Information that counsel advises Director is required to be disclosed.

(b)   Nonrecruitment of Employees.   Director hereby agrees that, for three (3) years following the Effective Time or for three (3) years following Director’s affiliation with Buyer or SNB as a director, employee, or consultant (whichever period is longer), Director shall not, without the prior written consent of the Buyer’s Chief Executive Officer, which consent may be withheld in the sole discretion of Buyer’s Chief Executive Officer, directly or indirectly solicit or recruit or attempt to solicit or recruit for employment or encourage to leave employment with Buyer or any of its Affiliated Companies, on his or her own behalf or on behalf of any other Person, (i) any then-current employee of Buyer or any of its Affiliated Companies or (ii) any employee of Seller who worked at Seller or any of its Affiliated Companies during Director’s services as a director of Seller or any Seller Affiliated Company and who has not ceased employment for a minimum of a six month period with Buyer, Seller, or any Affiliated Companies, as applicable. It is acknowledged that general advertisements shall not be deemed to violate this provision.

(c)   Nonsolicitation of Customers.   Director hereby agrees that, for three (3) years following the Effective Time or for three (3) years following Director’s affiliation with Buyer or SNB as a director, employee, or consultant (whichever period is longer), Director shall not, without the prior written consent of the Buyer’s Chief Executive Officer, which consent may be withheld in the sole discretion of Buyer’s Chief Executive Officer, directly or indirectly, on behalf of himself, herself, or of anyone other than Seller, Buyer, SNB, or any Affiliated Company, in the Restricted Area (as defined in Section 2(d) below), solicit or attempt to solicit any customer or client of Seller for the purpose of either (i) providing any Business Activities (as defined in Section 2(d)) or (ii) inducing such customer or client to cease, reduce, restrict, or divert its business with Seller, Buyer, SNB, or any Affiliated Company.

For purposes of this Agreement, “Compete” means to engage or participate 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.

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 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.

Board of Directors
Seacoast Banking Corporation of Florida
815 Colorado Avenue
Stuart, FL 34994

Ladies and Gentlemen:

Seacoast Banking Corporation of Florida (“SBC”), Seacoast National Bank, a wholly-owned subsidiary of SBC (“SNB” and together with SBC, “Seacoast”), Professional Holding Corp. (“Professional”) and Professional Bank, a wholly-owned subsidiary of Professional (“Bank”), are proposing to enter into an Agreement and Plan of Merger (the “Agreement”) pursuant to which Professional shall merge with and into SBC with SBC being the surviving corporation (the “Merger”). As set forth in the Agreement, at the Effective Time, each share of Professional Common Stock issued and outstanding immediately prior to the Effective Time, except for certain shares of Professional Common Stock as specified in the Agreement, shall be converted into the right to receive 0.8909 of a share of SBC Common Stock (the “Merger Consideration”), subject to the Merger Consideration Adjustment, as set forth in the Agreement. Capitalized terms used herein without definition shall have the meanings ascribed thereto in the Agreement. You have requested our opinion as to the fairness, from a financial point of view, of the Merger Consideration to Seacoast.

Piper Sandler & Co. (“Piper Sandler”, “we” or “our”), as part of its investment banking business, is regularly engaged in the valuation of financial institutions and their securities in connection with mergers and acquisitions and other corporate transactions. In connection with this opinion, we have reviewed and considered, among other things: (i) a draft of the Agreement, dated August 5, 2022; (ii) certain publicly available financial statements and other historical financial information of SBC and SNB that we deemed relevant; (iii) certain publicly available financial statements and other historical financial information of Professional and Bank that we deemed relevant; (iv) publicly available mean analyst balance sheet and earnings per share estimates for SBC for the years ending December 31, 2022 and December 31, 2023 with a long-term annual net income and balance sheet growth rate for the years ending December 31, 2024 through December 31, 2026, as provided by the senior management of Seacoast; (v) certain financial projection assumptions for Professional for the years ending December 31, 2022 through December 31, 2026, as provided by the senior management of Seacoast; (vi) the pro forma financial impact of the Merger on Seacoast based on certain assumptions relating to transaction expenses, purchase accounting adjustments and cost savings, as well as certain adjustments for current expected credit losses (CECL) accounting standards, as well as certain assumptions relating to the sale and reinvestment of Professional’s securities portfolio and the investment of Professional cash and equivalents at closing of the Merger, as provided by the senior management of Seacoast; (vii) the publicly reported historical price and trading activity for SBC Common Stock and Professional Common Stock, including a comparison of certain stock trading information for SBC Common Stock and Professional Common Stock and certain stock indices, as well as similar publicly available information for certain other companies, the securities of which are publicly traded; (viii) a comparison of certain financial and market information for SBC and Professional with similar financial institutions for which information is publicly available; (ix) the financial terms of certain recent business combinations in the bank and thrift industry (on a regional basis), to the extent publicly available; (x) the current market environment generally and the banking environment in particular; and (xi) such other information, financial studies, analyses and investigations and financial, economic and market criteria as we considered relevant. We also discussed with certain members of the senior management of Seacoast and its representatives the business, financial condition, results of operations and prospects of Seacoast and held similar discussions with certain members of the senior management of Professional and its representatives regarding the business, financial condition, results of operations and prospects of Professional.

B-1

In performing our review, we have 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 Seacoast or its representatives, or that was otherwise reviewed by us and we have assumed such accuracy and completeness for purposes of rendering this opinion without any independent verification or investigation. We have further relied on the assurances of the senior management of Seacoast that they are not aware of any facts or circumstances that would make any of such information inaccurate or misleading in any respect material to our analyses. We have not been asked to undertake, and have not undertaken, an independent verification of any such information and we do not assume any responsibility or liability for the accuracy or completeness thereof. We did not make an independent evaluation or perform an appraisal of the specific assets, the collateral securing assets or the liabilities (contingent or otherwise) of Seacoast or Professional, nor have we been furnished with any such evaluations or appraisals. We render no opinion on or evaluation of the collectability of any assets or the future performance of any loans of Seacoast or Professional. We did not make an independent evaluation of the adequacy of the allowance for loan losses of Seacoast or Professional, or the combined entity after the Merger, and we have not reviewed any individual credit files relating to Seacoast or Professional. We have assumed, with your consent, that the respective allowances for loan losses for both Seacoast and Professional are adequate to cover such losses and will be adequate on a pro forma basis for the combined entity.

In preparing its analyses, Piper Sandler used publicly available mean analyst balance sheet and earnings per share estimates for SBC for the years ending December 31, 2022 and December 31, 2023 with a long-term annual net income and balance sheet growth rate for the years ending December 31, 2024 through December 31, 2026, as provided by the senior management of Seacoast. In addition, Piper Sandler used certain financial projection assumptions for Professional for the years ending December 31, 2022 through December 31, 2026, as provided by the senior management of Seacoast. Piper Sandler also received and used in its pro forma analyses certain assumptions relating to transaction expenses, purchase accounting adjustments and cost savings, as well as certain adjustments for CECL accounting standards, as well as certain assumptions relating to the sale and reinvestment of Professional’s securities portfolio and the investment of Professional cash and equivalents at closing of the Merger, as provided by the senior management of Seacoast. With respect to the foregoing information, the senior management of Seacoast confirmed to us that such information reflected (or, in the case of the publicly available analyst estimates referred to above, were consistent with) the best currently available estimates and judgements of senior management as to the future financial performance of Seacoast and Professional, respectively, and we assumed that the financial results reflected in such information would be achieved. We express no opinion as to such estimates or judgements, or the assumptions on which they are based. We have also assumed that there has been no material change in Seacoast’s or Professional’s assets, financial condition, results of operations, business or prospects since the date of the most recent financial statements made available to us. We have assumed in all respects material to our analyses that Seacoast and Professional will remain as going concerns for all periods relevant to our analyses.

For purposes of our analyses we have assumed, at your direction and with your consent, that there will be no Merger Consideration Adjustment. We have also assumed, with your consent and to the extent material to our analyses, that (i) each of the parties to the Agreement will comply in all material respects with all material terms and conditions of the Agreement and all related agreements required to effect the Merger, that all of the representations and warranties contained in such agreements are true and correct in all material respects, that each of the parties to such agreements will perform in all material respects all of the covenants and other obligations required to be performed by such party under such agreements and that the conditions precedent in such agreements are not and will not be waived, (ii) in the course of obtaining the necessary regulatory or third party approvals, consents and releases with respect to the Merger, no delay, limitation, restriction or condition will be imposed that would have an adverse effect that would be material to our analyses of Seacoast, Professional or the Merger, or any related transactions, and (iii) the Merger and any related transactions will be consummated in accordance with the terms of the Agreement without any waiver, modification or amendment of any material term, condition or agreement thereof and in compliance with all applicable laws and other requirements. We express no opinion as to any legal, accounting or tax matters relating to the Merger and the other transactions contemplated by the Agreement.

B-2

Our opinion is necessarily based on financial, regulatory, economic, market and other conditions as in effect on, and the information made available to us as of, the date hereof. Events occurring after the date hereof could materially affect this opinion. We have not undertaken to update, revise, reaffirm or withdraw this opinion or otherwise comment upon events occurring after the date hereof. We express no opinion as to the trading value of SBC Common Stock or Professional Common Stock at any time or what the value of SBC Common Stock will be once it is actually received by the holders of Professional Common Stock.

We have acted as Seacoast’s financial advisor in connection with the Merger and will receive a fee for our services, which fee is contingent upon consummation of the Merger. We will also receive a fee for rendering this opinion, which opinion fee will be credited in full towards the advisory fee which will become payable to Piper Sandler upon consummation of the Merger. Seacoast has also agreed to indemnify us against certain claims and liabilities arising out of our engagement and to reimburse us for certain of our out-of-pocket expenses incurred in connection with our engagement. In the two years preceding the date hereof Piper Sandler has provided certain other investment banking services to Seacoast. In summary, Piper Sandler (i) acted as financial advisor to Seacoast in connection with Seacoast’s acquisition of Legacy Bank of Florida, which transaction closed in August 2021 and for which Piper Sandler received an advisory fee of approximately $925,000, (ii) acted as financial advisor to Seacoast in connection with Seacoast’s acquisition of Sabal Palm Bancorp, Inc. and Business Bank of Florida, Corp., which transactions closed in January 2022 and for which Piper Sandler received an aggregate advisory fee of approximately $1 million, (iii) acted as financial advisor to Seacoast in connection with Seacoast’s acquisition of Apollo Bancshares, Inc., which transaction was announced in March 2022 and for which Piper Sandler anticipates receiving an aggregate advisory fee of approximately $1.85 million, which fee is contingent upon the closing of the transaction, and (iv) acted as financial advisor to Seacoast in connection with Seacoast’s acquisition of Drummond Banking Company, which transaction was announced in May 2022 and for which Piper Sandler anticipates receiving an aggregate advisory fee of approximately $2 million, which fee is contingent upon the closing of the transaction. In addition, affiliates of Piper Sandler, Piper Sandler Hedging Services, LLC (“Piper Sandler Hedging”) and Piper Sandler Loan Strategies, LLC (“PSLS”), provided certain balance sheet management and risk mitigation advisory services as well as loan valuation services to Seacoast in 2022 for which Piper Sandler Hedging and PSLS received approximately $20,000 and $35,000 in compensation, respectively. In the two years preceding the date hereof Piper Sandler did not provide any investment banking services to Professional; provided, however, Piper Sandler Hedging provided certain balance sheet and risk mitigation advisory services to Professional in 2021 and 2022 for which PSLS received an aggregate fee of approximately $80,000. In addition, in the ordinary course of our business as a broker-dealer, we may purchase securities from and sell securities to Seacoast, Professional and their respective affiliates. We may also actively trade the equity and debt securities of Seacoast and Professional for our own account and for the accounts of our customers.

Our opinion is directed to the Board of Directors of Seacoast in connection with its consideration of the Agreement and the Merger and does not constitute a recommendation to any shareholder of Seacoast as to how any such shareholder should vote at any meeting of shareholders called to consider and vote upon the adoption of the Agreement and approval of the Merger. Our opinion is directed only as to the fairness, from a financial point of view, of the Merger Consideration to Seacoast and does not address the underlying business decision of Seacoast to engage in the Merger, the form or structure of the Merger or any other transactions contemplated in the Agreement, the relative merits of the Merger as compared to any other alternative transactions or business strategies that might exist for Seacoast or the effect of any other transaction in which Seacoast might engage. We also do not express any opinion as to the fairness of the amount or nature of the compensation to be received in the Merger by any Seacoast or Professional officer, director or employee, or class of such persons, if any, relative to the amount of compensation to be received by any other shareholder. This opinion has been approved by Piper Sandler’s fairness opinion committee. This opinion may not be reproduced without Piper Sandler’s prior written consent; provided, however, Piper Sandler will provide its consent for the opinion to be included in any regulatory filings, including the Proxy Statement/Prospectus, to be filed with the SEC and mailed to shareholders in connection with the Merger.

B-3

Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Merger Consideration is fair to Seacoast from a financial point of view.

Very truly yours,

APPENDIX C​

August 5, 2022

Board of Directors
Professional Holding Corp.
396 Alhambra Circle, Suite 255
Coral Gables, FL 33134

Dear Members of the Board:

We have acted as your financial advisor in connection with the proposed merger (the “Transaction”) of Professional Holding Corp. (the “Company”) with and into Seacoast Banking Corporation of Florida (the “Buyer”). You have requested that we provide our opinion (the “Opinion”) as investment bankers as to whether the consideration to be received by the common stockholders of the Company (solely in their capacity as such, the “Shareholders”) in the Transaction is fair to them from a financial point of view.

Pursuant to the Agreement and Plan of Merger (the “Agreement”) to be entered into by and between the Company and the Buyer, and subject to the terms, conditions and limitations set forth therein, we understand that, subject to potential adjustments as described in the Agreement, each outstanding share of the Company’s common stock will be converted into the right to receive 0.8909 shares of the Buyer’s common stock, which, based on the Buyer’s closing stock price of $36.45 on August 3, 2022, results in the expected consideration to be exchanged by the Buyer for all of the outstanding common stock, restricted stock, stock appreciation rights and options of the Company having an aggregate value of approximately $484.4 million. The terms and conditions of the Transaction are more fully set forth in the Agreement.

In connection with developing our Opinion we have:

(i)

reviewed certain publicly available financial statements and reports regarding the Company and the Buyer;

(ii)

reviewed certain audited financial statements regarding the Company and the Buyer;

(iii)

reviewed certain internal financial statements, management reports and other financial and operating data concerning the Company and the Buyer prepared by management of the Company and management of the Buyer, respectively;

(iv)

reviewed, on a pro forma basis, in reliance upon consensus research estimates and upon financial projections and other information and assumptions concerning the Company and the Buyer provided by management of the Company and management of the Buyer, respectively, the effect of the Transaction on the balance sheet, capitalization ratios, earnings and tangible book value both in the aggregate and, where applicable, on a per share basis of the Buyer;

(v)

reviewed the reported prices and trading activity for the common stock of the Company and the Buyer;

(vi)

compared the financial performance of the Company and the Buyer with that of certain other publicly-traded companies and their securities that we deemed relevant to our analysis of the Transaction;

(vii)

reviewed the financial terms, to the extent publicly available, of certain merger or acquisition transactions that we deemed relevant to our analysis of the Transaction;

C-1

(viii)

reviewed the most recent draft of the Agreement and related documents provided to us by the Company;

(ix)

discussed with management of the Company and management of the Buyer the operations of and future business prospects for the Company and the Buyer, respectively and the anticipated financial consequences of the Transaction to the Company and the Buyer, respectively;

(x)

assisted in your deliberations regarding the material terms of the Transaction and your negotiations with the Buyer; and

(xi)

performed such other analyses and provided such other services as we have deemed appropriate.

We have relied on the accuracy and completeness of the information, financial data and financial forecasts provided to us by the Company and the Buyer and of the other information reviewed by us in connection with the preparation of our Opinion, and our Opinion is based upon such information. We have not independently verified or undertaken any responsibility to independently verify the accuracy or completeness of any of such information, data or forecasts. Management of the Company and management of the Buyer have assured us that they are not aware of any relevant information that has been omitted or remains undisclosed to us. We have not assumed any responsibility for making or undertaking an independent evaluation or appraisal of any of the assets or liabilities of the Company or of the Buyer, and we have not been furnished with any such evaluations or appraisals; nor have we evaluated the solvency or fair value of the Company or of the Buyer under any laws relating to bankruptcy, insolvency or similar matters. We have not assumed any obligation to conduct any physical inspection of the properties, facilities, assets or liabilities (contingent or otherwise) of the Company or Buyer. We have not received or reviewed any individual loan or credit files nor have we made an independent evaluation of the adequacy of the allowance for loan and lease losses of the Company or the Buyer. We have not made an independent analysis of the effects of the COVID-19 pandemic, the invasion of Ukraine, potential future changes in the inflation rate or other related market developments or disruptions, or of any other disaster or adversity, on the business or prospects of the Company or the Buyer. With respect to the financial forecasts prepared by management of the Company and management of the Buyer, including the forecasts of potential cost savings and potential synergies, we have also assumed that such financial forecasts have been reasonably prepared and reflect the best currently available estimates and judgments of management of the Company and management of the Buyer, respectively, as to the future financial performance of the Company and the Buyer, respectively, and provide a reasonable basis for our analysis. We recognize that such financial forecasts are based on numerous variables, assumptions and judgments that are inherently uncertain (including, without limitation, factors related to general economic and competitive conditions) and that actual results could vary significantly from such forecasts, and we express no opinion as to the reliability of such financial projections and estimates or the assumptions upon which they are based.

As part of our investment banking business, we regularly issue fairness opinions and are continually engaged in the valuation of companies and their securities in connection with business reorganizations, private placements, negotiated underwritings, mergers and acquisitions and valuations for estate, corporate and other purposes. We are familiar with the Company and the Buyer. Affiliates and employees of Stephens Inc. (including, among others, employees involved in preparing this Opinion) own, in the aggregate, approximately two percent of the outstanding common stock of the Company. We issued periodic research reports regarding the business and prospects of the Company prior to the recent departure of our research analyst who was covering the Company. We make a market in the stock of the Company and the Buyer. While we have not received fees for providing investment banking or other services to the Buyer or the Company within the past two years, we served as the lead left bookrunner in connection with the initial public offering of the Company’s common stock, which priced on February 6, 2020, and as financial advisor for the Company in connection with the Company’s acquisition of Marquis Bancorp, Inc., which closed on March 26, 2020, and we received customary fees in connection with such assignments. We serve as financial adviser to the Company in connection with the Transaction, and we are entitled to receive from the Company reimbursement of our expenses and a fee for our services as financial adviser to the Company, a significant portion of which is contingent upon the consummation of the Transaction. We are also entitled to receive a fee from the Company for providing our Opinion to the Board of Directors of the Company. The Company has also agreed to indemnify us for certain liabilities arising out of our engagement, including

C-2

certain liabilities that could arise out of our providing this Opinion letter. We expect to pursue future investment banking services assignments with the participants in this Transaction. In the ordinary course of business, Stephens Inc. and its affiliates and employees at any time may hold long or short positions, and may trade or otherwise effect transactions as principal or for the accounts of customers, in debt, equity or derivative securities of any participants in the Transaction.

We are not legal, accounting, regulatory, or tax experts, and we have relied solely, and without independent verification, on the assessments of the Company and its other advisors with respect to such matters. We have assumed, with your consent, that the Transaction will not result in any materially adverse legal, regulatory, accounting or tax consequences for the Company or its shareholders and that any reviews of legal, accounting, regulatory or tax issues conducted as a result of the Transaction will be resolved favorably to the Company and its shareholders. We do not express any opinion as to any tax or other consequences that might result from the Transaction.

The Opinion is necessarily based upon market, economic and other conditions as they exist and can be evaluated on the date hereof and on the information made available to us as of the date hereof. Market price data used in connection with this Opinion is based on reported market closing prices as of August 3, 2022. It should be understood that subsequent developments may affect this Opinion and that we do not have any obligation to update, revise or reaffirm this Opinion or otherwise comment on events occurring after the date hereof. We further note that the current volatility and disruption in the credit and financial markets relating to, among other things, the COVID-19 pandemic, the invasion of Ukraine or potential future changes in inflation rates may or may not have an effect on the Company or the Buyer, and we are not expressing an opinion as to the effects of such volatility or such disruption on the Transaction or any party to the Transaction. We further express no opinion as to the prices at which shares of the Buyer’s or Company’s common stock may trade at any time subsequent to the announcement of the Transaction.

In connection with developing this Opinion, we have assumed that, in all respects material to our analyses:

(i)

the Transaction and any related transactions will be consummated on the terms of the latest draft of the Agreement provided to us, without material waiver or modification;

(ii)

the representations and warranties of each party in the Agreement and in all related documents and instruments referred to in the Agreement are true and correct;

(iii)

each party to the Agreement and all related documents will perform all of the covenants and agreements required to be performed by such party under such documents;

(iv)

all conditions to the completion of the Transaction will be satisfied within the time frames contemplated by the Agreement without any waivers;

(v)

that in the course of obtaining the necessary regulatory, lending or other consents or approvals (contractual or otherwise) for the Transaction and any related transactions, no restrictions, including any divestiture requirements or amendments or modifications, will be imposed that would have a material adverse effect on the contemplated benefits of the Transaction to the Shareholders;

(vi)

there has been no material change in the assets, liabilities, financial condition, results of operations, business or prospects of the Company or the Buyer since the date of the most recent financial statements made available to us, and that no legal, political, economic, regulatory or other development has occurred that will adversely impact the Company or the Buyer; and

(vii)

the Transaction will be consummated in a manner that complies with applicable law and regulations.

This Opinion is directed to, and is for the use and benefit of, the Board of Directors of the Company (in its capacity as such) solely for purposes of assisting with its evaluation of the Transaction. Our Opinion does not address the merits of the underlying decision by the Company to engage in the Transaction, the merits of the Transaction as compared to other alternatives potentially available to the Company or the relative effects of any alternative transaction in which the Company might engage, nor is it intended to be a

C-3

recommendation to any person or entity as to any specific action that should be taken in connection with the Transaction, including with respect to how to vote or act with respect to the Transaction. This Opinion is not intended to confer any rights or remedies upon any other person or entity. In addition, except as explicitly set forth in this letter, you have not asked us to address, and this Opinion does not address, the fairness to, or any other consideration of, the holders of any class of securities, creditors or other constituencies of the Company. We have not been asked to express any opinion, and do not express any opinion, as to the fairness of the amount or nature of the compensation to any of the Company’s officers, directors or employees, or to any group of such officers, directors or employees, whether relative to the compensation to other shareholders of the Company or otherwise.

Our Fairness Opinion Committee has approved the Opinion set forth in this letter. Neither this Opinion nor its substance may be disclosed by you to anyone other than your advisors without our written permission. Notwithstanding the foregoing, this Opinion and a summary discussion of our underlying analyses and role as financial adviser to the Company may be included in communications to shareholders of the Company, provided that this Opinion letter is reproduced in its entirety, and we approve of the content of such disclosures prior to any filing, distribution or publication of such shareholder communications and prior to distribution of any amendments thereto.

Based on the foregoing and our general experience as investment bankers, and subject to the limitations, assumptions and qualifications stated herein, we are of the opinion, on the date hereof, that the consideration to be received by the Shareholders in the Transaction is fair to them from a financial point of view.

Very truly yours,

STEPHENS INC.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of Professional Holding Corp.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheet of Professional Holding Corp. (the Company) as of December 31, 2021, the related consolidated statements of income and comprehensive income, stockholders’ equity and cash flows for the year ended December 31, 2021, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2021, and the results of its operations and its cash flows for the year ended December 31, 2021, in conformity with U.S. generally accepted accounting principles.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

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

PROFESSIONAL HOLDING CORP.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
For the years ended December 31, 2021, and 2020.
(Tables in thousands, except share data)

NOTE 1 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of organization and corporate reorganization:   Professional Holding Corp. (the Corporation and/or the Company) is a financial holding company headquartered in Coral Gables, Florida, with one wholly owned subsidiary, Professional Bank, a Florida-chartered commercial bank (the Bank). Professional Holding Corp. was formed on January 14, 2014 and became the sole shareholder of the Bank on July 1, 2014 through the consummation of a statutory share exchange with the Bank’s then current shareholders whereby holders of the Bank’s common stock were exchanged for an equal number of shares of the Company’s Class A Voting Common Stock, par value $0.01 per share. On March 26, 2020, the Company closed its acquisition of Marquis Bancorp. (MBI) and its wholly owned subsidiary, Marquis Bank, headquartered in Coral Gables, Florida. Each share of MBI common stock issued and outstanding immediately prior to closing was converted into 1.2048 shares of the Company’s Class A common stock, with cash paid in lieu of fractional shares. The Company’s assets consist of cash and business activity as of December 31, 2021, and 2020, pertaining to the investment in the Bank.

Professional Bank commenced banking operations on September 8, 2008. The Bank is focused on meeting the financial service needs of individuals and businesses in South Florida. The Bank offers a full complement of commercial banking products and services. Deposit products include traditional checking, savings and money market accounts, as well as IRAs and certificates of deposit. The Bank’s deposits are insured up to applicable limits by the Federal Deposit Insurance Corporation (the FDIC). Lending products include commercial loans, residential mortgage loans, home equity lines of credit, installment loans and consumer lines of credit. The Bank is subject to regulation, examination and supervision by the Federal Reserve Bank (its primary regulator), the FDIC and the Office of Financial Regulation for the State of Florida (the OFR).

The consolidated financial statements include Professional Holding Corp. and its wholly-owned subsidiary, Professional Bank. Intercompany transactions and balances are eliminated in consolidation. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Certain prior period amounts have been reclassified to conform to the current period presentation.

Concentration risks:   Most of the Company’s business activity is with customers located in South Florida. Therefore, the Company’s exposure to credit risk is significantly affected by changes in the economy of Miami-Dade, Broward and Palm Beach counties.

A summary of the Company’s significant accounting policies is as follows:

Use of estimates:   Preparation of these consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.

Cash flows:   For purposes of the statement of cash flows, cash and cash equivalents include cash, due from bank, interest-earning deposits, and federal funds sold, all of which had origination maturities of less than 90 days. Net cash flows are reported for customer loan and deposit transactions, federal funds purchased and repurchase agreements.

In certain situations, banks are required to maintain cash reserves in the form of vault cash or in an account with the Federal Reserve Bank or in noninterest-earning accounts with other qualified banks. This requirement is based on the Bank’s amount of transaction deposit accounts. The Bank’s cash reserve requirements was $0 on December 31, 2021, and 2020.

D-7

Business combinations:   The Company accounts for business combinations using the acquisition method of accounting. Under this method of accounting, the acquired company’s net assets are recorded at fair value as of the date of acquisition, and the results of operations of the acquired company are combined with our results from that date forward. Acquisition costs are expensed when incurred. The difference between the purchase price and the fair value of the net assets acquired (including identified intangibles) is recorded as goodwill in the consolidated statements of financial condition. A change in the initial estimate of any contingent earn out amount is recorded to non-interest expense in the consolidated statements of income.

Acquired loans are initially recorded at their acquisition-date fair values using Level 3 inputs with no carryover of related allowance for loan losses. Any allowance for loan loss on these loans reflect losses incurred after the acquisition. The Company determines the fair value of the acquired loans based on a discounted cash flow methodology that involves assumptions and judgments as to credit risk, expected lifetime losses, environmental factors, discount rates, expected payments and expected prepayments.

For additional detail regarding business combinations, specifically the acquisition of Marquis Bancorp, Inc. see Note 23.

Securities:   Securities may be classified as either trading, held to maturity or available for sale. Trading securities (if any) are held principally for resale and recorded at their fair value with changes in fair value included in income. Held to maturity securities are those which the Company has the positive intent and ability to hold to maturity and are reported at amortized cost. Equity securities are carried at fair value, with changes in fair value reported in net income. Equity securities without readily determinable fair values are carried at cost, minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment. Available for sale securities consist of securities not classified as trading securities nor as held to maturity securities. Unrealized holding gains and losses on available for sale securities are excluded from income and reported in comprehensive income or loss. Gains and losses on the sale of available for sale securities are recorded on the trade date and are determined using the specific-identification method. Premiums and discounts on securities available for sale are recognized in interest income using the interest method over the period to maturity or call date. There were no investment securities classified as trading as of December 31, 2021, and 2020.

Management evaluates securities for other-than-temporary impairment (OTTI) on at least a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. For securities in an unrealized loss position, management considers the extent and duration of the unrealized loss, and the financial condition and near-term prospects of the issuer. Management also assesses whether it intends to sell, or it is more likely than not that it will be required to sell, a security in an unrealized loss position before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: (1) OTTI related to credit loss, which must be recognized in the income statement and (2) OTTI related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. For equity securities, the entire amount of impairment is recognized through income (if any).

Loans:   Loans that management has the intent and the Bank has the ability to hold for the foreseeable future or until maturity or pay-off are reported at their outstanding principal balance, adjusted for any charge-offs, the allowance for loan losses, and any deferred fees or costs.

The recognition of interest income on a loan is discontinued when, in management’s opinion, it is probable the borrower is unable to meet payments as they become due or when the loan becomes 90 days past due, whichever occurs first, at which time the loan is placed on non-accrual. All interest accrued but not collected for loans that are placed on nonaccrual or charged-off is reversed against interest income. The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual status. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.

Loans held for sale:   are recorded at the lower of cost or fair value on an individual basis. Gains and losses on loan sales are included in noninterest income.

D-8

Troubled debt restructurings:   Troubled debt restructurings are separately identified for impairment disclosures and are measured at the present value of estimated future cash flows using the loan’s effective rate at inception. If a troubled debt restructuring is considered to be a collateral dependent loan, the loan is reported, net, at the fair value of the collateral. For troubled debt restructurings that subsequently default, the Company determines the amount of reserve in accordance with the accounting policy for the allowance for loan losses.

Allowance for loan losses:   The allowance for loan losses, a valuation allowance for probable incurred credit losses, is established as losses are estimated to have occurred through a provision for loan losses charged to income. Loan losses are charged against the allowance when management believes the uncollectability of a loan balance is probable. Subsequent recoveries, if any, are credited to the allowance.

The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral and prevailing economic conditions. The allowance for loan losses is also reviewed by the Board of Directors on a quarterly basis. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available.

The allowance consists of specific and general components. The specific component relates to loans that are considered impaired. For such loans, an allowance is established when the discounted expected future cash flows or collateral value or observable market price of the impaired loan is lower than the carrying value of that loan. The general component covers all other loans and is based on historical loss experience (if any) adjusted for qualitative factors.

The historical loss component of the allowance is determined by a combination of losses recognized by portfolio segment over the preceding five years, if any, and if no losses were recognized, the Bank uses historical loss data from peer banks. This is supplemented by the risks for each portfolio segment. Risk factors impacting loans in each of the portfolio segments include changes in property values and changes in credit availability. The historical experience and/or peer bank risk factors are adjusted for qualitative factors such as economic conditions including trends in real estate sales, housing statistics, local unemployment rates, commercial and retail vacancy rates and the past due loans and default rates as well as other trends or uncertainties that could affect management’s estimate of probable incurred losses.

A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the original contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis for each class of loans by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral if the loan is collateral-dependent.

The Company also maintains a reserve for losses on unfunded commitments. This reserve is reflected as a component of other liabilities and, in management’s opinion, is sufficient to cover probable losses inherent in the commitments. Management tracks the amount and trends in unused commitments and takes into consideration the same factors as those considered for purposes of the allowance for loan losses on outstanding loans.

The Company has divided the loan portfolio into five portfolio segments and classes, each with different risk characteristics and methodologies for assessing risk. All loans are underwritten in accordance with polices set forth and approved by the Company’s Board of Directors. The portfolio segments and class are the same and are identified by the Company as follows:

D-9

Commercial real estate:   Commercial real estate loans consist of loans to finance real estate purchases, refinancing’s, expansions and improvements to commercial properties. These loans are secured by first liens on office buildings, apartments, farms, retail and mixed-use properties, churches, warehouses and restaurants located within the market area. Additionally, in response to the COVID-19 pandemic, the Company has granted loans to qualified businesses under the Paycheck Protection Program. The Company’s underwriting analysis includes credit verification, independent appraisals, a review of the borrower’s financial condition, and a detailed analysis of the borrower’s underlying cash flows. Commercial real estate loans are usually larger than residential loans and involve greater credit risk. The repayment of these loans largely depends on the results of operations and management of these properties. Adverse economic conditions also affect the repayment ability to a greater extent than that of residential real estate loans.

Residential real estate:   The Company originates mostly adjustable-rate mortgage loans for the purchase or refinance of residential properties. These loans are collateralized by first or second mortgages on owner-occupied, second homes or investment residential properties located in the Company’s market area. The Company’s underwriting analysis includes repayment capacity and source, value of the underlying property and credit history stability.

Commercial:   Commercial business loans and lines of credit consist of loans to small and medium-sized companies in the Company’s market area. Commercial loans are generally used for working capital purposes or for acquiring equipment, inventory or furniture. Primarily all of the Company’s commercial loans are secured loans, along with a small amount of unsecured loans. The Company’s underwriting analysis consists of a review of the financial statements of the borrower, the lending history of the borrower, the debt service capabilities of the borrower, the projected cash flows of the business, the value of the collateral, if any, and whether the loan is guaranteed by the principals of the borrower. These loans are generally secured by accounts receivable, inventory and equipment. Commercial loans are typically made on the basis of the borrower’s ability to make repayment from the cash flow of the borrower’s business, which makes them of higher risk than residential loans and the collateral securing commercial loans may be difficult to appraise and may fluctuate in value based on the success of the business. The Company seeks to minimize these risks through our underwriting standards.

Construction and land development:   Construction loans consist of loans to individuals for the construction of their primary residences and, to a limited extent, loans to builders and commercial borrowers. To the extent construction loans are not made to owner-occupants of single-family homes, they are more vulnerable to changes in economic conditions. Further, the nature of these loans is such that they are more difficult to evaluate and monitor. The risk of loss on a construction loan is dependent largely upon the accuracy of the initial estimate of the property’s value upon completion of the project and the estimated cost (including interest) of the project.

Consumer and other:   Consumer loans mainly consist of variable-rate and fixed-rate personal loans and lines of credit and installment loans. Most of the Company’s consumer loans share approximately the same level of risk as residential mortgages.

Federal Reserve Bank stock (FRB):   The Company is a member of its regional Federal Reserve Bank. FRB stock is carried at cost, classified as a restricted security and periodically evaluated for impairment based on the ultimate recovery of par value.

Federal Home Loan Bank stock (FHLB):   The Bank is a member of the FHLB system. Members are required to own a certain amount of stock based on the level of borrowings and other factors. FHLB stock is carried at cost, classified as a restricted security and periodically evaluated for impairment based on the ultimate recovery of par value.

Foreclosed assets:   Assets acquired through or instead of loan foreclosure are initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. These assets are subsequently accounted for at lower of cost or fair value less estimated costs to sell. If fair value declines subsequent to foreclosure, a valuation allowance is recorded through expense. Operating costs after acquisition are expensed. As of December 31, 2021, and 2020, there were no foreclosed assets.

Premises and equipment:   Leasehold improvements, computer hardware and software, furniture, fixtures and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and

D-10

amortization are computed using the straight-line method over the shorter of the estimated useful life of each type of asset or the length of time the Company expects to lease the property.

Bank-owned life insurance:   Bank-owned life insurance is recorded at the estimated amount that can be realized under the insurance contract at the consolidated balance sheet date, which is the cash surrender value adjusted for other changes or amounts that are probable at settlement.

Goodwill and other intangible assets:   Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired. Goodwill is not amortized and is subject to at least annual assessments for impairment by applying a fair value-based test. The Company’s goodwill is tested for impairment on an annual basis. Quarterly, the Company evaluates whether a triggering event has occurred that would necessitate further review of goodwill for potential impairment. Per accounting guidance, the Company will first assess qualitative factors. If an assessment of qualitative factors determines it is more likely than not that the fair value of a reporting unit exceeds its carrying amount, then a goodwill impairment test is not required. The Company typically performs its annual impairment testing during the fourth quarter.

Intangible assets with definite useful lives, such as core deposit intangible assets arising from bank acquisitions, are amortized over their estimated useful lives.

Revenue recognition:   Revenue from Contracts with Customers (“ASC 606”), establishes principles for reporting information about the nature, amount, timing and uncertainty of revenue and cash flows arising from the entity’s contracts to provide goods or services to customers. The core principle requires an entity to recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration that it expects to be entitled to receive in exchange for those goods or services recognized as performance obligations are satisfied.

The majority of the Company’s revenue-generating transactions are not subject to ASC 606, including revenue generated from financial instruments, such as our loans, letters of credit, and investment securities, and revenue related to the sale of loans in the secondary market, as these activities are subject to other GAAP requirements discussed elsewhere within our disclosures. The Company recognizes revenue from these activities as it is earned based on contractual terms, as transactions occur, or as services are provided and collectability is reasonably assured. Descriptions of the major revenue-generating activities that are within the scope of ASC 606, which are presented in the accompanying statements of income as components of non-interest income are as follows:

Service charges on deposit accounts — these represent general service fees for monthly account maintenance and activity- or transaction-based fees and consist of transaction-based revenue, time-based revenue (service period), item-based revenue or some other individual attribute-based revenue. Revenue is recognized when the Company’s performance obligation is completed which is generally monthly for account maintenance services or when a transaction has been completed. Payment for such performance obligations are generally received at the time the performance obligations are satisfied.

Fair value measurement:   Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values:

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

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

Level 3 — Significant unobservable inputs that reflect a Company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability.

Fair value must be recorded for certain assets and liabilities every reporting period on a recurring basis or, under certain circumstances, on a non-recurring basis.

D-11

For additional detail regarding fair value measurement, see Note 14.

Transfer of financial assets:   Transfers of financial assets or a participating interest in an entire financial asset are accounted for as sales, when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when: (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.

Off-balance sheet financial instruments:   In the ordinary course of business, the Company has entered into off-balance sheet financial instruments consisting of unused lines of credit, commitments to extend credit and standby letters of credit. Such financial instruments are recorded in the financial statements when they are funded.

Share-based compensation:   Compensation cost is recognized for stock options and restricted stock awards issued to employees, based on the fair value of these awards at the date of grant. A Black Scholes model is utilized to estimate the fair value of stock options, while the market price of the Company’s common stock at the date of grant is used for restricted stock awards.

Compensation cost is recognized over the required service period, generally defined as the vesting period. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award if conditions are met for recognition. The Company recognizes forfeitures as they occur and reverses the previously recorded compensation cost associated with the forfeiture.

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

A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded.

The Company recognizes interest and/or penalties related to income tax matters in income tax expense.

Earnings per common share:   Basic earnings per common share is net income divided by the weighted average number of common shares outstanding during the period. Diluted earnings per common share includes the dilutive effect of additional potential common shares issuable under stock options.

Comprehensive income:   GAAP requires that recognized revenue, expenses, gains and losses be included in net income. Although certain changes in assets and liabilities, such as unrealized gains and losses on available for sale securities, are reported as a separate component of the equity section of the balance sheets, such items, along with net income, are components of comprehensive income.

Loss contingencies:   Loss contingencies, including claims and legal actions arising in the ordinary course of business (if any), are recorded as liabilities when the likelihood of loss is probable, and an amount or range of loss can be reasonably estimated. Management does not currently believe there are such matters that will have a material effect on the consolidated financial statements.

Dividend restriction:   Banking regulations require maintaining certain capital levels and may limit the dividends paid by the bank to the holding company or by the holding company to shareholders.

Operating segments:   While the chief decision-makers monitor the revenue streams of the various products and services, operations are managed and financial performance is evaluated on a Company-wide basis. Discrete financial information is not available other than on a Company-wide basis. Accordingly, all of the financial services operations are considered by management to be aggregated in one reportable operating segment.

D-12

Adoption of new accounting pronouncements:

ASU 2019-12, Income Taxes (Topic 740)
Description	In December 2019, FASB issued guidance which simplifies the accounting for income taxes by removing multiple exceptions to the general principals in Topic 740.
Date of Adoption	The standard is effective for public business entities for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2020.
Effect on the Consolidated Financial Statements	The new guidance did not materially impact the Company’s Consolidated Financial Statements or disclosures.

ASU 2020-04, Financial Instruments — Reference Rate Reform (Topic 848)
Description	In March 2020, FASB released ASU 2020-4 — Reference Rate Reform (Topic 848), which provides optional guidance to ease the accounting burden in accounting for, or recognizing the effects from, reference rate reform on financial reporting. The new standard is a result of the London Interbank Offered Rate (“LIBOR”) likely being discontinued as an available benchmark rate. The standard is elective and provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, or other transactions that reference LIBOR, or another reference rate expected to be discontinued.
Date of Adoption	The amendments in the update are effective for all entities between March 12, 2020, and December 31, 2022. The Company adopted this standard on January 1, 2021.
Effect on the Consolidated Financial Statements	The Company has identified its products that utilize LIBOR and has implemented enhanced fallback language to facilitate the transition to alternative reference rates. The new guidance did not materially impact the Company’s Consolidated Financial Statements or disclosures.

NOTE 2 — EARNINGS PER SHARE

Basic earnings per common share is computed by dividing net income available to common shareholders by the weighted average number of shares of common stock outstanding during the year. Diluted earnings per common share is computed by dividing net income available to common shareholders by the weighted average number of shares of common stock outstanding plus the effect of employee stock options during the year.

The unrealized holding losses within the investment portfolio are considered to be temporary and are mainly due to changes in the interest rate cycle. The unrealized loss positions may fluctuate positively or negatively with changes in interest rates or spreads. Since SBA loan pools and mortgage-backed securities are government sponsored entities that are highly rated, the decline in fair value is attributable to changes in interest rates and not credit quality. The Company does not have any securities in an OTTI position. The Company does not have the intent to sell these securities and it is likely that it will not be required to sell the securities before their anticipated recovery. The Company does not consider these securities to be other-than-temporarily impaired on December 31, 2021. No credit losses were recognized in operations during the years ended December 31, 2021, and 2020.

Loan premiums for loans purchased are amortized over the life of the loan with acceleration upon the increase in principal paydowns or payoffs. On December 31, 2021, and 2020, loan premiums for purchased loans were $0.4 million and $0.6 million, respectively.

There are no loans over 90 days past due and accruing as of December 31, 2021, and 2020.

On December 31, 2021, there were four impaired loans (consisting of nonaccrual loans, troubled debt restructured loans, loans past due 90 days or more and still accruing interest and other loans based on management’s judgement) with both unpaid principal balance and recorded investments totaling $2.2 million. Three of these loans were impaired loans with a recorded investment of $2.1 million with an allowance of $1.3 million. Also, there was one substandard accruing loan with a recorded investment of $2.3 million with no allowance. The average net investment on the impaired residential real estate and commercial loans during 2021 was $0.5 million. Residential real estate loans had $3.4 thousand of interest income recognized during the year ended December 31, 2021, which was equal to the cash basis interest income.

On December 31, 2020, there were six impaired loans (consisting of nonaccrual loans, troubled debt restructured loans, loans past due 90 days or more and still accruing interest and other loans based on management’s judgment) with recorded investments totaling $13.1 million, of which there were three impaired loans with a recorded investment of $10.4 million on nonaccrual with an allowance of with $8.3 million and one substandard accruing loan with a recorded investment of $2.4 million with no allowance. The average net investment on the impaired residential real estate and commercial loans during 2020 was $2.2 million. The residential real estate loans had $13 thousand of interest income recognized during the year ended December 31, 2020, which was equal to cash basis interest income.

Troubled Debt Restructurings:

The principal carrying balances of loans that met the criteria for consideration as a troubled debt restructuring were $0.1 million and $0.3 million as of December 31, 2021, and December 31, 2020, respectively. The Company has allocated no specific reserves to customers whose loan terms have been modified in troubled debt restructurings as of December 31, 2021, and December 31, 2020. The Company has not committed any additional amounts to customers whose loans are classified as a troubled debt restructuring.

There were no loans modified as troubled debt restructurings during the period ending December 31, 2021, or December 31, 2020.

Credit Quality Indicators:

The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt including: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. Generally, all credits greater than $1.0 million are reviewed no less than annually to monitor and adjust, if necessary, the credit risk profile. Loans classified as substandard or special mention are reviewed quarterly by the Company for further evaluation to determine if they are appropriately classified and whether there is any impairment. Beyond the annual review, all loans are graded upon initial issuance. In addition, during the renewal process of any loan, as well as if a loan becomes past due, the Company will determine the appropriate loan grade.

Loans excluded from the review process above are generally classified as pass credits until: (a) they become past due; (b) management becomes aware of deterioration in the credit worthiness of the borrower;

D-18

or (c) the customer contacts the Company for a modification. In these circumstances, the loan is specifically evaluated for potential classification as to special mention, substandard, doubtful, or even charged-off. The Company uses the following definitions for risk ratings:

Pass:   A Pass loan’s primary source of loan repayment is satisfactory, with secondary sources very likely to be realized if necessary. The pass category includes the following:

Riskless:   Loans that are fully secured by liquid, properly margined collateral (listed stock, bonds, or other securities; savings accounts; certificates of deposit; loans or that portion thereof which are guaranteed by the United States Government or agencies backed by the “full faith and credit” thereof; loans secured by properly executed letters of credit from prime financial institutions).

High Quality Risk:   Loans to recognized national companies and well-seasoned companies that enjoy ready access to major capital markets or to a range of financing alternatives. Borrower’s public debt offerings are accorded highest ratings by recognized rating agencies, e.g., Moody’s or Standard & Poor’s. Companies display sound financial conditions and consistent superior income performance. The borrower’s trends and those of the industry to which it belongs are positive.

Satisfactory Risk:   Loans to borrowers, reasonably well established, that display satisfactory financial conditions, operating results and excellent future potential. Capacity to service debt is amply demonstrated. Current financial strength, while financially adequate, may be deficient in a number of respects. Normal comfort levels are achieved through a closely monitored collateral position and/or the strength of outside guarantors.

Moderate Risk:   Loans to borrowers who are in non-compliance with periodic reporting requirements of the loan agreement, and any other credit file documentation deficiencies, which do not otherwise affect the borrower’s credit risk profile. This may include borrowers who fail to supply updated financial information that supports the adequacy of the primary source of repayment to service the Bank’s debt and prevents bank management to evaluate the borrower’s current debt service capacity. Existing loans will include those with consistent track record of timely loan payments, no material adverse changes to underlying collateral, and no material adverse change to guarantor(s) financial capacity, evidenced by public record searches.

Special mention:   A Special Mention loan has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in the deterioration of the repayment prospects for the asset or the Company’s credit position at some future date. Special Mention loans are not adversely classified and do not expose an institution to sufficient risk to warrant adverse classification.

Substandard:   A Substandard loan is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected.

Doubtful:   A loan classified Doubtful has all the weaknesses inherent in one classified Substandard with the added characteristics that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.

Loss:   A loan classified Loss is considered uncollectible and of such little value that continuance as a bankable asset is not warranted. This classification does not mean that the asset has absolutely no recovery or salvage value, but rather it is not practical or desirable to defer writing off this basically worthless asset even though partial recovery may be affected in the future.

Nonperforming Assets

As of December 31, 2021, the Company had nonperforming assets of $2.1 million, or 0.08% of total assets, compared to nonperforming assets of $10.4 million, or 0.51% of total assets, on December 31, 2020. The Bank’s charge-off policy for impaired loans is similar to its charge-off policy for all loans in that loans are charged-off in the month when a determination of a confirmed loss is made on a loan. The decrease in nonperforming assets was driven by charge-offs of $8.3 million of impaired loans during the year ended December 31, 2021. The Company had charge-offs of $0.3 million during the year ended December 31, 2020.

Paycheck Protection Program (PPP)

The Company has participated in the PPP offered through the United States Small Business Administration (SBA) by way of the Coronavirus Aid Relief and Economic Security (CARES) Act that was passed at the end of the first quarter 2020. As a qualified SBA lender, the Company was automatically authorized to originate PPP loans. To help clients, the Company added an online PPP application form and automated the PPP loan closing documentation process. The Company processed, closed and funded 2,287 small business loans representing $340.5 million in relief proceeds, of which 1,931 loans totaling $280.6 million were forgiven by the SBA and the balance was $58.6 million on December 31, 2021. The majority of these loans were initially pledged to the Federal Reserve as part of the Paycheck Protection Program Liquidity Facility (PPPLF). The PPPLF pledged loans are non-recourse to the Company. However, the Company paid off all of the PPPLF advances during the first and second quarter of 2021.

Debt Service Relief Requests Related to COVID-19

The Company has reviewed and processed numerous debt service relief requests in accordance with Section 4013 of the CARES Act and interagency guidelines published by federal banking regulators on March 13, 2020. As currently interpreted by the agencies, the guidelines assert that short-term modifications made on good faith for reasons related to the COVID-19 pandemic to borrowers who were current prior to such relief are not considered TDRs. These modifications included deferrals of principal and interest, modification to interest only, and deferrals to escrow requirements. The modifications had varying terms up to six months. As of December 31, 2021, all these loans had returned to normal payment schedules.

Amounts drawn under this line of credit bears interest at the Prime Rate, as announced by The Wall Street Journal from time to time as its prime rate, and its obligations under this line of credit are secured by shares of the capital stock of the Bank, which we have pledged as security. On December 31, 2021, there were $10.0 million outstanding borrowings under this line of credit. On December 31, 2020, there were no outstanding borrowings under this line of credit.

NOTE 10 — BORROWINGS

Federal Home Loan Bank Advances

FHLB Advances.   The FHLB allows the Company to borrow up to 25% of its assets on a blanket floating lien status collateralized by certain securities and loans. As of December 31, 2021, approximately $235.3 million in total loans were pledged as collateral for our FHLB borrowings. We utilize these borrowings to meet liquidity needs and to fund certain fixed rate loans in our portfolio. As of December 31, 2021, we had $35.0 million in outstanding advances, $28.7 million in outstanding letters of credit, and $113.0 million in additional available borrowing capacity from the FHLB based on the collateral that we have currently pledged.

D-25

On December 31, 2021, and 2020, advances from the Federal Home Loan Bank were as follows:

(Dollars in thousands)	2021			2020
Maturities through 2030, fixed rate at 0.81%, averaging 0.81%	​	$	5,000	​	$	10,000

Each advance is payable at its maturity date, with a prepayment penalty for fixed rate advances. The advances were collateralized by $235.3 million and $189.9 million of first mortgage loans under a blanket lien arrangement on December 31, 2021, and 2020, respectively. Based on this collateral and the Company’s holdings of FHLB stock, the Company is eligible to borrow up to a total of $176.7 million as of December 31, 2021. However, given the collateral that was currently pledged, the Company had $113.0 million in available borrowing capacity from the FHLB.

NOTE 14 — OTHER EMPLOYEE BENEFITS

The Company, through the Bank, has adopted a 401(k) benefit plan (the Plan) covering substantially all eligible employees and contains a safe harbor provision whereby all employees who initially enroll are 100% vested. The Company, at its discretion, matches the employees’ annual contribution up to 4% of their annual salary. The Company contributed approximately $0.6 million to the Plan in 2021, and 2020.

NOTE 15 — FAIR VALUE

Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values:

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

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

Level 3 — Significant unobservable inputs that reflect a Company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability.

The Company used the following methods and significant assumptions to estimate fair value:

Cash and cash equivalents:   The carrying amounts of cash and cash equivalents approximate their fair value.

Securities available for sale:   Where quoted prices are available in an active market, securities are classified within Level 1 of the valuation hierarchy. Level 1 securities include highly liquid government bonds, certain mortgage products and exchange-traded equities. If quoted market prices are not available, then fair values are estimated by using pricing models, quoted prices of securities with similar characteristics, or discounted cash flows. Examples of such instruments, which would generally be classified within Level 2 of the valuation hierarchy, include certain collateralized mortgage and debt obligations, corporate bonds, municipal bonds and United States agency notes. In certain cases where there is limited activity or less transparency around inputs to the valuation, securities are classified within Level 3 of the valuation hierarchy. Securities classified within Level 3 might include certain residual interests in securitizations and other less liquid securities. As of December 31, 2021, and 2020, all securities available for sale were Level 2.

Securities held to maturity:   Reported at fair value utilizing Level 2 inputs. The estimated fair value is determined based on market quotes when available. If not available, quoted market prices of similar securities, discounted cash flow analysis, pricing models and observable market data are used in determining fair market value.

Equity securities:   The Company values equity securities at readily determinable market values based on the closing price at the end of each period. Changes in fair value are recognized through net income.

Loans:   Fair values are estimated for portfolios of loans with similar characteristics. Loans are segregated by type, such as commercial or residential mortgage. Each loan category is further segmented into fixed and adjustable rate interest terms as well as performing and nonperforming categories. The fair value of loans is calculated by discounting scheduled cash flows through the estimated life including prepayment considerations and estimated market discount rates that reflect the risks inherent to the loan. The calculation of the fair value considers market driven variables including credit related factors and reflects an exit price as defined in ASC Topic 820.

Loans held for sale:   The carrying amounts of loans held for sale approximate their fair values.

D-29

Federal Home Loan Bank stock:   It is not practical to determine fair value due to restrictions placed on transferability.

Federal Reserve Bank stock:   It is not practical to determine fair value due to restrictions placed on transferability.

Accrued interest receivable:   The carrying amounts of accrued interest approximate their fair values.

Deposits:   The fair values disclosed for demand, NOW, money-market and savings deposits are, by definition, equal to the amount payable on demand at the reporting date (carrying amount). Fair values for fixed-rate time deposits are estimated using current market rates offered for remaining or similar maturities.

Federal Home Loan Bank advances:   Fair values are estimated using discounted cash flow analysis based on the Bank’s current incremental borrowing rates for similar types of borrowing arrangements.

Subordinated debt:   The fair value was determined by using a discounted cash flow method using a market participant discount rate for similar instruments.

Line of Credit:   The carrying amounts of the line of credit approximate their fair values.

Off-balance-sheet instruments:   Fair values for off-balance-sheet lending commitments are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties’ credit standing.

Interest rate swaps:   The fair value of interest rate swaps is estimated using inputs that are observable or that can be corroborated by corroborated by observable market data and therefore are classified as Level 2. The fair value estimations include primarily market observable inputs.

Assets and liabilities measured at fair value on a recurring basis, are summarized below:

As of December 31, 2020, the Company did not hold any interest rate swaps.

There were no securities reclassified into or out of Level 3 during the year ended December 31, 2021, and 2020.

Impaired loans:   The fair value of impaired loans with specific allocations of the allowance for loan losses is generally based on recent real estate appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available for similar loans and collateral underlying such loans. Such adjustments result in a Level 3 classification of the inputs for determining fair value. Non-real estate collateral may be valued using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation, and management’s expertise and knowledge of the client and client’s business, resulting in a Level 3 fair value classification. Impaired loans are evaluated on a quarterly basis for additional impairment and adjusted in accordance with the allowance policy.

Assets measured at fair value on a non-recurring basis are summarized below:

NOTE 16 — CUSTOMER DERIVATIVES — INTEREST RATE SWAPS

During the first quarter of 2021, the Company established a program whereby it originates a variable rate loan and enters into a variable-to-fixed interest rate swap with the customer. The Company also enters into an offsetting swap with a swap dealer. These back-to-back swap agreements are intended to offset each other and allow the Company to originate a variable rate loan, while providing a contract for fixed interest payments for the customer. The net cash flow for the Company is equal to the interest income received from a variable rate loan originated with the customer. The swaps with both the customers and third parties are not designated as hedges under FASB ASC Topic 815, Derivatives and Hedging, and are marked to market through earnings. As the swaps are structured to offset each other, changes to the underlying benchmark interest rates considered in the valuation of these instruments do not result in an impact to earnings; however, there may be fair value adjustments related to credit quality variations between counterparties, which may impact earnings as required by FASB ASC Topic 820, Fair Value Measurement and Disclosure (“ASC 820”). During the year ended December 31, 2021, the Company recorded eleven swap transactions with clients having a total notional amount of $46.8 million, offset by eleven swap transactions with dealers having a total notional amount of $46.8 million. Additionally, we recorded $0.6 million in back-to-back swap fee income. The fair value of these derivatives is based on a market standard discounted cash flow approach. The Company incorporates credit value adjustments on derivatives to properly reflect the respective counterparty’s nonperformance risk in the fair value measurements of its derivatives. As of December 31, 2021, the Bank’s asset fair value position in other assets was $1.1 million and liability fair value position in other liabilities was $1.1 million, which were fully collateralized with pledged securities held with counterparty in excess of the exposure amount at quarter end.

NOTE 17 — LOAN COMMITMENTS AND OTHER RELATED ACTIVITIES

Some financial instruments, such as loan commitments, credit lines, letters of credit, and overdraft protection, are issued to meet customer financing needs. These are agreements to provide credit or to support the credit of others, as long as conditions established in the contract are met, and usually have expiration dates. Commitments may expire without being used. Off-balance-sheet risk to credit loss exists

D-33

up to the face amount of these instruments, although material losses are not anticipated. The same credit policies are used to make such commitments as are used for loans, including obtaining collateral at exercise of the commitment.

The contractual amounts of financial instruments with off-balance-sheet risk on December 31, 2021, and 2020 were as follows:

(Dollars in thousands)	2021			2020
Available lines of credit	​	$	415,402	​	$	355,927
Unfunded loan commitments – fixed	​	​	62,126	​	​	28,414
Unfunded loan commitments – variable	​	​	46,698	​	​	12,215
Standby letters of credit	​	​	12,095	​	​	13,036
Commercial letters of credit	​	​	2,765	​	​	1,028
Total credit extension commitments	​	$	539,086	​	$	410,620

NOTE 18 — DIVIDENDS

The Company is limited in the amount of cash dividends that it may pay. The amount of cash dividends that may be paid is based on the Company’s net income of the current year combined with the Bank’s retained income of the preceding two years, as defined by state banking regulations. However, for any dividend declaration, the Company must consider additional factors such as the amount of current period net income, liquidity, asset quality, capital adequacy and economic conditions at the Bank. It is likely that these factors would further limit the amount of dividends which the Company could declare. In addition, bank regulators have the authority to prohibit banks from paying dividends if they deem such payment to be an unsafe or unsound practice.

NOTE 19 — REGULATORY CAPITAL MATTERS

Banks and bank holding companies are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance-sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate regulatory action.

Under the Basel Committee on Banking Supervision’s capital guidelines for United States banks (Basel III rules), the Bank must hold a capital conservation buffer above the adequately capitalized risk-based capital ratios. The capital conservation buffer for 2021 and 2020 was 2.50%. The net unrealized gain or loss on available for sale securities is not included in computing regulatory capital. Management believes as of December 31, 2021, the Bank met all capital adequacy requirements to which it was subject.

Prompt corrective action regulations provide five classifications: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized, although these terms are not used to represent overall financial condition. If adequately capitalized, regulatory approval is required to accept brokered deposits. If undercapitalized, capital distributions are limited, as is asset growth and expansion, and capital restoration plans are required. On December 31, 2021, and 2020, the most recent regulatory notifications categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes have changed the institution’s category. Based on changes to the Federal Reserve’s definition of a “Small Bank Holding Company” that increased the threshold to $3 billion in assets in August 2018, the Company is not currently subject to separate minimum capital measurements. At such time as the Company reaches the $3 billion asset level, it will again be subject to capital measurements independent of the Bank. For comparison purposes, the Company’s ratios are included in following discussion as well, all of which would have exceeded the “well-capitalized” level had the Company been subject to separate capital minimums.

Actual and required capital amounts and ratios are presented below on December 31, 2021, and 2020. The required amounts for capital adequacy shown below do not include the capital conservation buffer previously discussed.

NOTE 20 — LEGAL CONTINGENCIES

The Company is subject to legal proceedings and claims, which arise in the ordinary course of business. In the opinion of management, the amount of ultimate liability with respect to these actions will not materially affect the financial position or results of operations of the Company.

NOTE 21 — STOCK BASED COMPENSATION

Restricted Stock

An award of restricted stock involves the immediate transfer by the Company to the participant of a specific number of shares of our Class A Common Stock, which are subject to a risk of forfeiture and a restriction on transferability. This restriction will lapse following a stated period of time. The participant does not pay for the restricted stock and has all of the rights of a holder of a share of our Class A Common Stock (except for the restriction on transferability), including the right to vote and receive dividends unless otherwise determined by the Compensation Committee and set forth in the award agreement.

The Company initially limited the aggregate number of shares of our Class A voting common stock to be awarded under the 2019 Equity Incentive Plan (the “2019 Plan”) as restricted stock to 676,741 shares. However, the 2019 Plan provides for the automatic increase (but not decrease) on the first day of each fiscal

D-35

year. Thus, on December 31, 2021, the total share reserve was 676,741. The Company has 198,587 shares of restricted stock outstanding, at a weighted average exercise price of $16.23 to employees under the 2019 Equity Incentive Plan as of December 31, 2021, for which the Company did not receive, nor will it receive, any monetary consideration. Therefore, there were 478,154 restricted shares available to be issued on December 31, 2021. As of December 31, 2021, there was approximately $2.4 million in unrecognized compensation expense in regards to restricted stock that will be recognized over a three-year period.

A summary of the status of the Company’s non-vested restricted shares were as follows:

​	Number of Shares		Weighted- Average Grant-Date Fair Value
Balance on January 1, 2020	​	99,216	​	$	18.98

Stock Option Plan

The Company’s 2009 Employee Share Option Plan (the Plan, as amended in April 2012), permits the grant of share options to certain key employees and directors for up to 265,000 shares of common stock. Option awards are generally granted with an exercise price equal to the market price of the Company common stock at the date of grant; those option awards have vesting periods up to three years and have a ten-year contractual term. Currently, the Company has a sufficient number of shares to satisfy expected share option exercises.

Marquis Bancorp Inc. 2017 Stock Option Plan

Pursuant to the terms of the MBI acquisition, the stock options under the Marquis Bancorp Inc. 2017 Stock Option Plan, vested or unvested, were converted into a substantially equivalent number of options to purchase PFHD Class A Common Stock, subject to substantially the same terms and conditions as immediately prior to the MBI acquisition. At December 31, 2021, there were 743,585 options associated with the Marquis Bancorp Inc. 2017 Stock Option Plan conversion and the Company has a sufficient number of shares outstanding to satisfy the expected share exercises.

The fair value of each option award is estimated on the date of grant using a closed form option valuation (Black-Scholes) model that uses the assumptions noted in the table below. The expected volatility is the five years volatility of the Company stocks in the NASDAQ OMX ABA Community Bank Index. The computation of expected life is calculated based on the simplified method. The risk free interest rate for all periods is based upon a zero coupon United States Treasury bond with a similar life as the option at the time of grant.

There were no stock options granted during the year ended December 31, 2021, and 2020.

On December 31, 2021, and 2020, there was $0 and $49 thousand of total unrecognized compensation expense related to nonvested share-based compensation arrangements granted under the Plan, respectively. The cost is expected to be recognized over a weighted-average period of approximately four years. The total fair value of shares vesting and recognized as compensation expense was approximately $49 thousand and $243 thousand for the years ended December 31, 2021, and 2020, respectively. Additionally, during the year ended December 31, 2021, there were 94,171 shares of Class A common stock issued for cashless option exercises at a weighted-average exercise price of $9.57 and during the year ended December 31, 2020, there were 7,819 shares of Class A common stock issued for cashless option exercises at a weighted-average exercise price of $6.64.

During 2014, the Plan was modified with the Corporate reorganization described in Note 1 whereby the Company assumed the same provisions of the Plan established at the Bank in previous years. The options exchanged were equal in fair value and in terms to the original options received. No additional compensation expense was recognized as a result of the modification.

Employee Stock Purchase Plan

The Company’s 2014 Associate Stock Purchase Plan allows employees to purchase stock at a discounted price of fair market-value. The maximum amount of shares available under the plan is 2,000,000. The discount is 5% of fair market value with the difference recorded as compensation expense. The maximum an employee can participate is $25 thousand per calendar year. The December 31, 2021, fair value of the stock was determined based on the market price of the common stock ($19.16 per share). The Company ended the Employee Stock Purchase Plan on June 30, 2021.

Stock Appreciation Rights

The Company’s 2012 Stock Appreciation Rights Plan (SARs, as amended in 2014) is a grant awarded to selected employees and directors in recognition of their current and future contributions to the Company. A SAR unit provides the employee or director a “right” to the future appreciation of value in a share of common stock of the Company. The SAR unit is awarded at the then fair market value of the stock share as of the date of the grant (base price). As the stock appreciates in value, the difference between the base price and the fair market value is the potential benefit to the employee after it vests. Unlike a stock option, the

D-37

employee is not required to pay any amount to exercise the SAR as the net amount of the increase in the stock value is paid (either in cash or stock) at the payment date after vesting occurs.

The SAR unit becomes vested at the earlier of: (i) five years of continuous service with the Company from the date of the grant; (ii) upon a liquidity event of the Company; and (iii) death or disability. Units granted under the SAR agreements have a base price ranging from $15.43 to $19.16 per common stock as of December 31, 2021. Total available units under the SAR program amount to 1.2 million as of December 31, 2021.

There were no SARs granted, exercised, or forfeited for the years ending December 31, 2021, and 2020. As of December 31, 2021, the company determined that a payout to employees under the SAR plan is unlikely and therefore no accrual has been made. Total SARs outstanding as of December 31, 2021, were 932,000.

NOTE 22 — LEASES

Operating leases in which the Company is the lessee are recorded as right-of-use (“ROU”) assets and operating lease liabilities, including premises and equipment and other liabilities, respectively on the Consolidated Balance Sheets. Currently the Company does not have any lessor leases (formerly known as capital leases) to report on its financials.

The Company’s ROU assets are classified under other assets on the Balance Sheet. The ROU liabilities are classified under other liabilities. The Company recorded $0.2 million new ROU assets during the year ended December 31, 2021, and recorded $2.0 million during the year ended December 31, 2020. The total amount of ROU liabilities were $5.1 million and $6.5 million on December 31, 2021, and 2020, respectively.

The majority of the Company’s lessee leases are operating leases and consist of leased real estate for branches and operations centers. The Company elected the short term lease recognition exemption for all leases that qualify, meaning those with terms under twelve months. The ROU assets represent the Company’s right to use the underlying assets during the lease term and operating liabilities represent the obligation to make lease payments arising from the lease. ROU assets and operating lease liabilities are recognized at lease commencement. Options to extend and renew leases are generally exercised under normal circumstances. Advance notification is required prior to termination, and any noticing period is often limited to the months prior to renewal. Variable payments generally consist of common area maintenance and taxes. Rent escalations are generally specified by a payment schedule or are subject to a defined formula. The Company also does not separate lease and non-lease components for all leases, the majority of which consist of real estate common area maintenance expenses. Generally, leases do not include guaranteed residual values, but instead typically specify that the leased premises are to be returned in satisfactory condition with the Company liable for damages.

Lease cost for the year ended December 31, 2021, and 2020 consists of:

(Dollars in thousands)	Year Ended December 31, 2021			Year Ended December 31, 2020
Operating lease and interest cost	​	$	1,464	​	$	1,816

Total undiscounted cash flows	​	​	6,205
Discount on cash flows	​	​	(1,056)
Total operating lease liabilities	​	$	5,149

On June 19, 2020, the Company exercised an option to early terminate a lease for a former operational office of Marquis Bank and a branch located in Coral Gables (the “Closed Offices”). The Closed Offices were located less than one mile from the Bank’s already established Coral Gables location. The cost to exercise the option on the Closed Offices was $322.8 thousand and decreased the life of the lease by approximately 15 months. As a result of exercising the option, the lease terminated in March 2021 as opposed to June 2022. This option resulted in savings of over $400 thousand in lease payments plus expenses. The cost of the option was amortized through the end of the lease in March 2021.

NOTE 24 — BUSINESS COMBINATION

Acquisition of Marquis Bancorp, Inc.

On March 26, 2020, the Company closed its acquisition of Marquis Bancorp. (MBI) and its wholly owned subsidiary, Marquis Bank, headquartered in Coral Gables, Florida. Each share of MBI common

D-40

stock issued and outstanding immediately prior to closing was converted into 1.2048 shares of the Company’s Class A common stock, with cash paid in lieu of fractional shares. The Company issued 4,227,816 shares of its Class A Common Stock as consideration in the acquisition. No MBI shareholders exercised appraisal rights. In addition, all stock options of MBI granted and outstanding on the closing date of the acquisition were converted into an option to purchase shares of the Company’s Class A Common Stock based on the exchange ratio.

MBI results of operations were included in the Company’s results beginning March 27, 2020. Acquisition-related costs of $0.7 million and $3.3 million are included in non-interest expense in the Company’s income statement for the year ended December 31, 2021, and 2020, respectively. The fair value of the Class A common shares issued as part of the consideration paid for MBI was determined on the basis of the closing price of the Company’s common shares on the acquisition date. The fair value of options included a measurement period adjustment to incorporate the fair value of options using the Black Scholes method.

The acquisition of MBI was accounted for under the acquisition method in accordance with ASC Topic 805, Business Combinations. Goodwill of $24.6 million arising from the acquisition consisted of operational efficiencies and potential cost savings through consolidating and integrating MBI’s operations into the Company’s existing operations. The fair values of the assets acquired and liabilities assumed were finalized during the fourth quarter of 2020. Determining the fair values of assets acquired and liabilities assumed, especially the loan portfolio, core deposit intangibles, goodwill and time deposits involved significant judgement regarding methods of assumptions used to calculate the estimated fair values.

The following tables summarize the consideration paid for MBI and the estimated and final fair values of the assets acquired, and liabilities assumed at the date of the MBI acquisition, net of total consideration paid:

Acquired loans are initially recorded at their acquisition-date fair values using Level 3 inputs. Refer to Note 13, Fair Value, for a discussion of the fair value hierarchy. Fair values are based on a discounted cash

D-41

flow methodology that involves assumptions and judgments as to credit risk, expected lifetime losses, environmental factors, discount rates, expected payments and expected prepayments. Specifically, the Company prepared three separate loan fair value adjustments that it believes a market participant might employ in estimating the entire fair value adjustment necessary under ASC 820-10 for the acquired loan portfolio. The three separate fair valuation methodologies employed are: (i) an interest rate loan fair value adjustment, (ii) a general credit fair value adjustment, and (iii) a specific credit fair value adjustment for purchased credit impaired (“PCI”) loans subject to ASC 310-30 provisions. The acquired loans were recorded at fair value at the acquisition date without carryover of MBI’s previously established allowance for loan losses. The fair value of the financial assets acquired included loans receivable with a book balance, prior to fair value adjustments, of $539.9 million.

The credit fair value adjustment on PCI loans represents the portion of the loan balances that have been deemed uncollectible based on the Company’s expectations of future cash flows for each respective loan. The fair value of purchased financial assets with credit deterioration was $4.6 million on the date of acquisition. The gross contractual amounts receivable relating to the purchased financial assets with credit deterioration was $8.8 million. The Company estimates, on the date of acquisition, that $3.6 million of the contractual cash flows specific to the purchased financial assets with credit deterioration will not be collected.

For loans acquired without evidence of credit deterioration, the Company prepared interest rate loan fair value and credit fair value adjustments. Loans were grouped into homogeneous pools by characteristics such as loan type, term, collateral and rate. Market rates for similar loans were obtained from various internal and external data sources and reviewed for reasonableness. Fair value adjustments related to loans acquired without evidence of credit deterioration will be recognized as interest income over the expected life of the loans.

For PCI loans, acquired with evidence of credit deterioration, the Company prepared a specific credit risk fair value adjustment in accordance with ASC 310-30. The fair value adjustment of $3.5 million represents the present value of expected cash flows at market participant discount rates in accordance with ASC 310-30. The accretable discount will be recognized on a level yield basis.

The fair value of the core deposit intangible was determined based on a discounted cash flow method using a discount rate commensurate with market participants. To calculate cash flows, the sum of deposit account servicing costs (net of deposit fee income) and interest expense on deposits was compared to the cost of alternative funding sources available to the Company. The expected cash flows of the deposit base included estimated attrition rates. The core deposit intangible asset was valued at $1.6 million and will be amortized over ten years using the sum-of-the years digit method.

The fair value adjustment for time deposits represents a premium from the value of the contractual repayments of fixed-maturity deposits using prevailing market interest rates for similar-term time deposits. The time deposit was valued at $2.8 million and is being amortized into income on a level yield amortization method over the contractual life of the deposits.

The fair value adjustment of FHLB advances was determined based upon an estimated fair value received from the FHLB Atlanta. The FHLB advances was valued at $0.1 million and will be amortized into the remaining life of the advances.

The fair value of subordinated debt was determined by using a discounted cash flow method using a market participant discount rate for similar instruments. The subordinated debt was fair valued at a premium of $0.5 million and will be amortized over the expected life of the debt.

In connection with the acquisition of MBI, the Company recorded a net deferred income tax asset of $5.4 million related to MBI’s effects of fair value adjustments resulting from applying the purchase method of accounting.

NOTE 25 — SUBSEQUENT EVENTS

On January 13, 2022, the Company completed a private placement of $25.0 million in fixed-to-floating rate subordinated notes payable due 2032. The Notes will bear interest at a fixed annual rate of 3.375% for

D-42

the first five years and will reset quarterly thereafter to the then current three-month Secured Overnight Financing Rate (SOFR) plus 203 basis points. The Notes are redeemable by the Company at its option, in whole or in part, on or after the fifth anniversary of the issue date. The Company intends to use the net proceeds from the sale of the subordinate notes for general corporate purposes.

On January 24, 2022, the Company increased the availability under its revolving line of credit at Valley National Bank, N.A. from $10.0 million to $25.0 million and extended the maturity date to March 1, 2023.

PROFESSIONAL HOLDING CORP.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)
(Tables in thousands, except share data)

NOTE 1 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation:

The accompanying unaudited consolidated financial statements of Professional Holding Corp. and its subsidiary, Professional Bank (the “Bank” and collectively with Professional Holding Corp., the “Company”), have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information. Accordingly, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements. In the opinion of management, adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Certain prior period amounts have been reclassified to conform to the current period presentation.

Operating results for the six months ended June 30, 2022, are not necessarily indicative of the results that may be expected for the year ending December 31, 2022, or any other period. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021.

Use of Estimates:

The preparation of these financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.

New accounting standards that have not yet been adopted:

The following provides a brief description of accounting standards that have been issued but are not yet adopted that could have a material effect on the Company’s financial statements:

ASU 2022-02, Financial Instruments — Credit Losses (Topic 326)

Description	In March 2022, FASB issued ASU 2022-02 which eliminates the guidance on troubled debt restructurings and requires entities to evaluate all loan modifications to determine if they result in a new loan or a continuation of the existing loan. ASU 2022-02 also requires that entities disclose current-period gross charge-offs by year of origination for loans and leases.
Date of Adoption	ASU 2022-02 is effective January 1, 2023.
Effect on the Consolidated Financial Statements	This ASU will have an impact on our financial statement disclosures but not a material impact on our financial statements.

ASU 2022-03, Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions

Description	In June 2022, FASB issued ASU 2022-03 which clarifies that a contractual sale restriction should not be considered in measuring fair value. ASU 2022-03 also requires that entities disclose certain qualitative and quantitative information about securities with contractual sale restrictions.
Date of Adoption	ASU 2022-03 is effective January 1, 2023.
Effect on the Consolidated Financial Statements	We are evaluating the impact of this ASU, however it is not believed to be material.

D-48

NOTE 2 — EARNINGS PER SHARE

Basic earnings per common share is computed by dividing net income available to common stockholders by the weighted average number of shares of common stock outstanding during the year. Diluted earnings per common share is computed by dividing net income available to common stockholders by the weighted average number of shares of common stock outstanding plus the effect of employee stock awards during the year.

As of June 30, 2022, and December 31, 2021, corporate bonds were comprised of investments in the financial services industry. During the six months ended June 30, 2022, the net investment portfolio decreased by $2.8 million primarily due to $18.2 million in investment calls, redemptions and paydowns, coupled with unrealized losses of $14.3 million during the year with a related tax effect of $3.6 million, partially offset

D-50

by purchases of approximately $30.7 million in mortgage-backed securities (“MBS”) community development district bonds (“CDD”), and municipal bonds.

Total securities pledged as of June 30, 2022, and December 31, 2021, were $1.9 million and $2.4 million, respectively, which included securities pledged for derivative swap transactions and pledged for public funds.

The amortized cost and fair value of debt securities are shown by contractual maturity. Expected maturities may differ from contractual maturities if borrowers have the right to call or prepay obligations with or without call or prepayment penalties. Securities not due at a single maturity date are shown separately. The scheduled maturities of securities as of June 30, 2022, are as follows:

On June 30, 2022, and December 31, 2021, there were no holdings of securities of any one issuer, other than the U.S. Government and its agencies, in an amount greater than 10% of stockholders’ equity. On June 30, 2022, and December 31, 2021, the number of investment positions that are in an unrealized loss position were 198 and 92, respectively.

The tables below indicate the fair value of debt securities with unrealized losses and for the period of time of which these losses were outstanding on June 30, 2022, and December 31, 2021, respectively, aggregated by major security type and length of time in a continuous unrealized loss position:

The unrealized holding losses within the investment portfolio are considered to be temporary and are mainly due to changes in the interest rate cycle. The unrealized loss positions may fluctuate positively or negatively with changes in interest rates or spreads. Since SBA loan pools and mortgage-backed securities are government sponsored entities that are highly rated, the decline in fair value is attributable to changes in interest rates and not credit quality. The Company does not have any securities in an Other Than Temporary Impairment (“OTTI”) position. The Company does not intend to sell these securities and it is likely that it will not be required to sell the securities before their anticipated recovery. No credit losses were recognized during the six months ended June 30, 2022, or during the year ended December 31, 2021.

The recorded investment in loans excludes accrued interest receivable due to immateriality.

On June 30, 2022, and December 31, 2021, there were $245.4 million and $235.3 million, respectively in total loans pledged to the Federal Home Loan Bank (“FHLB”).

Loan premiums for loans purchased are amortized over the life of the loan with acceleration upon the increase in principal paydowns or payoffs. On June 30, 2022, and December 31, 2021, loan premiums for purchased loans were $0.3 million and $0.4 million, respectively. Net discounts for loans acquired through business acquisitions totaled $9.9 million and $13.0 million, as of June 30, 2022, and December 31, 2021, respectively.

Troubled Debt Restructurings:

The principal carrying balances of loans that met the criteria for consideration as troubled debt restructurings (“TDR”) were $1.0 million and $55 thousand as of June 30, 2022, and December 31, 2021, respectively. The Company has allocated no specific reserves to customers whose loan terms have been modified in troubled debt restructurings as of June 30, 2022, and December 31, 2021. The Company has not committed any additional amounts to customers whose loans are classified as a troubled debt restructuring.

Credit Quality Indicators:

The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt including: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. Generally, all credits greater than $1.0 million are reviewed at least annually to monitor and adjust, if necessary, the credit risk profile. Loans classified as substandard or special mention are reviewed quarterly by the Company for further evaluation to determine if they are appropriately classified and whether there is any impairment. Beyond the annual review, all loans are graded upon initial issuance. In addition, during the renewal process of any loan, as well as if a loan becomes past due, the Company will determine the appropriate loan grade.

Loans excluded from the review process above are generally classified as pass credits until: (a) they become past due; (b) management becomes aware of deterioration in the creditworthiness of the borrower;

D-53

or (c) the customer contacts the Company for a modification. In these circumstances, the loan is specifically evaluated for potential classification as to special mention, substandard, doubtful, or even charged-off. The Company uses the following definitions for risk ratings:

Pass:   A Pass loan’s primary source of loan repayment is satisfactory, with secondary sources very likely to be realized if necessary. The pass category includes the following:

•

Riskless:   Loans that are fully secured by liquid, properly margined collateral (listed stock, bonds, or other securities; savings accounts; certificates of deposit; loans or that portion thereof which are guaranteed by the U.S. Government or agencies backed by the “full faith and credit” thereof; loans secured by properly executed letters of credit from prime financial institutions).

•

High Quality Risk:   Loans to recognized national companies and well-seasoned companies that enjoy ready access to major capital markets or to a range of financing alternatives. Borrower’s public debt offerings are accorded highest ratings by recognized rating agencies, e.g., Moody’s or Standard & Poor’s. Companies display sound financial conditions and consistent superior income performance. The borrower’s trends and those of the industry to which it belongs are positive.

•

Satisfactory Risk:   Loans to borrowers, reasonably well established, that display satisfactory financial conditions, operating results, and excellent future potential. Capacity to service debt is amply demonstrated. Current financial strength, while financially adequate, may be deficient in a number of respects. Normal comfort levels are achieved through a closely monitored collateral position and/or the strength of outside guarantors.

•

Moderate Risk:   Loans to borrowers who are in non-compliance with periodic reporting requirements of the loan agreement, and any other credit file documentation deficiencies, which do not otherwise affect the borrower’s credit risk profile. This may include borrowers who fail to supply updated financial information that supports the adequacy of the primary source of repayment to service the Bank’s debt and prevents bank management to evaluate the borrower’s current debt service capacity. Existing loans will include those with consistent track record of timely loan payments, no material adverse changes to underlying collateral, and no material adverse change to guarantor(s) financial capacity, evidenced by public record searches.

Special mention:   A Special Mention loan has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in the deterioration of the repayment prospects for the asset or the Company’s credit position at some future date. Special Mention loans are not adversely classified and do not expose an institution to sufficient risk to warrant adverse classification.

Substandard:   A Substandard loan is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected.

Doubtful:   A loan classified Doubtful has all the weaknesses inherent in one classified Substandard with the added characteristics that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.

Loss:   A loan classified Loss is considered uncollectible and of such little value that continuance as a bankable asset is not warranted. This classification does not mean that the asset has absolutely no recovery or salvage value, but rather it is not practical or desirable to defer writing off this basically worthless asset even though partial recovery may be affected in the future.

Banks may be required to maintain cash reserves in the form of vault cash or in an account with the Federal Reserve Bank or in noninterest-earning accounts with other qualified banks. This requirement is based on the Bank’s amount of transaction deposit accounts. Due to the amount of transaction deposit accounts, the Bank was not required to have cash reserve requirements on June 30, 2022, and December 31, 2021. Additionally, the Company had $92.5 million and $84.4 million, in Qualified Public Deposits (“QPD”) that require a portion of the deposit to be pledged as collateral as of June 30, 2022, and December 31, 2021.

NOTE 7 — DEBT AND BORROWINGS

Subordinated Debt.

On January 13, 2022, the Company completed a private placement of $25.0 million in fixed-to-floating rate subordinated notes payable due 2032. The Notes will bear interest at a fixed annual rate of 3.38% for the first five years and will reset quarterly thereafter to the then current three-month Secured Overnight Financing Rate (SOFR) plus 203 basis points. The Notes are redeemable by the Company at its option, in whole or in part, on or after the fifth anniversary of the issue date. The Company used the net proceeds from the sale of the subordinate notes for general corporate purposes.

Valley National Line of Credit.

The Company maintains a $25.0 million secured revolving line of credit with Valley National Bank, N.A with a maturity date of March 1, 2023. Amounts drawn under this line of credit bear interest at the Prime Rate, as announced by The Wall Street Journal from time to time as its prime rate, and its obligations under this line of credit are secured by shares of the capital stock of the Bank, which we have pledged as security. On June 30, 2022, there were no outstanding borrowings under this line of credit compared to $10.0 million on December 31, 2021.

The Company uses short-term and long-term borrowings to supplement deposits to fund lending and investment activities.

Federal Home Loan Bank Advances

FHLB Advances. The FHLB allows the Company to borrow up to 25% of its assets on a blanket floating lien status collateralized by certain securities and loans. As of June 30, 2022, approximately $245.4 million in total loans were pledged as collateral for potential FHLB borrowings and FHLB letters of credit. We utilize these borrowings to meet liquidity needs and to fund certain fixed rate loans in our portfolio. As of June 30, 2022, we had no outstanding advances, $28.7 million in outstanding letters of credit, and $153.3 million in additional available borrowing capacity from the FHLB based on the collateral that we have currently pledged.

There are three levels of inputs that may be used to measure fair values:

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

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

Level 3 — Significant unobservable inputs that reflect a Company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability.

D-60

The Company used the following methods and significant assumptions to estimate fair value:

Cash and cash equivalents:   The carrying amounts of cash and cash equivalents approximate their fair value.

Securities available for sale:   Where quoted prices are available in an active market, securities are classified within Level 1 of the valuation hierarchy. Level 1 securities include highly liquid government bonds, certain mortgage products and exchange-traded equities. If quoted market prices are not available, then fair values are estimated by using pricing models, quoted prices of securities with similar characteristics, or discounted cash flows. Examples of such instruments, which would generally be classified within Level 2 of the valuation hierarchy, include certain collateralized mortgage and debt obligations, corporate bonds, municipal bonds and U.S. agency notes. In certain cases where there is limited activity or less transparency around inputs to the valuation, securities are classified within Level 3 of the valuation hierarchy. Securities classified within Level 3 might include certain residual interests in securitizations and other less liquid securities. As of June 30, 2022, and December 31, 2021, all securities available for sale were Level 2.

Securities held to maturity:   Reported at fair value utilizing Level 2 inputs. The estimated fair value is determined based on market quotes when available. If not available, quoted market prices of similar securities, discounted cash flow analysis, pricing models and observable market data are used in determining fair market value.

Equity securities:   The Company values equity securities at readily determinable market values based on the closing price at the end of each period. Changes in fair value are recognized through net income.

Loans:   Fair values are estimated for portfolios of loans with similar characteristics. Loans are segregated by type, such as commercial or residential mortgage. Each loan category is further segmented into fixed and adjustable rate interest terms as well as performing and non-performing categories. The fair value of loans is calculated by discounting scheduled cash flows through the estimated life including prepayment considerations and estimated market discount rates that reflect the risks inherent to the loan. The calculation of the fair value considers market driven variables including credit related factors and reflects an exit price as defined in ASC Topic 820.

Loans held for sale:   The carrying amounts of loans held for sale approximate their fair values.

Federal Home Loan Bank stock:   It is not practical to determine fair value due to restrictions placed on transferability.

Federal Reserve Bank stock:   It is not practical to determine fair value due to restrictions placed on transferability.

Accrued interest receivable:   The carrying amounts of accrued interest approximate their fair values.

Deposits:   The fair values disclosed for demand, NOW, money-market and savings deposits are, by definition, equal to the amount payable on demand at the reporting date (that is, their carrying amounts). Fair values for fixed-rate time deposits are estimated using a current market rates offered for remaining or similar maturities.

Federal Home Loan Bank advances:   Fair values are estimated using discounted cash flow analysis based on the Bank’s current incremental borrowing rates for similar types of borrowing arrangements.

Subordinated debt:   The fair value was determined by using a discounted cash flow method using a market participant discount rate for similar instruments.

Line of credit:   The carrying amounts of the line of credit approximate their fair values.

Off-balance-sheet instruments:   Fair values for off-balance-sheet lending commitments are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties’ credit standing.

Interest rate swaps:   The fair value of interest rate swaps is estimated using inputs that are observable or that can be corroborated by observable market data and therefore are classified as Level 2. The fair value estimations include primarily market observable inputs.

D-61

There were no securities reclassified into or out of Level 3 during the six months ended June 30, 2022, or for the year ended December 31, 2021.

Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis:

Impaired loans:   The fair value of impaired loans with specific allocations of the allowance for loan losses is generally based on recent real estate appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available for similar loans and collateral underlying such loans. Such adjustments result in a Level 3 classification of the inputs for determining fair value. Non-real estate collateral may be valued using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation, and management’s expertise and knowledge of the client and client’s business, resulting in a Level 3 fair value classification. Impaired loans are evaluated on a quarterly basis for additional impairment and adjusted in accordance with the allowance policy.

Assets measured at fair value on a non-recurring basis are summarized below:

NOTE 10 — CUSTOMER DERIVATIVES — INTEREST RATE SWAPS

During the first quarter of 2021, the Company established a program whereby it originates a variable rate loan and enters into a variable-to-fixed interest rate swap with the customer. The Company also enters into an offsetting swap with a swap dealer. These back-to-back swap agreements are intended to offset each other and allow the Company to originate a variable rate loan, while providing a contract for fixed interest payments for the customer. The net cash flow for the Company is equal to the interest income received from a variable rate loan originated with the customer. The swaps are not designated as hedges under FASB ASC Topic 815, Derivatives and Hedging, and are marked to market through earnings. As the swaps are structured to offset each other, changes to the underlying benchmark interest rates considered in the valuation of these instruments do not result in an impact to earnings; however, there may be fair value adjustments related to credit quality variations between counterparties, which may impact earnings as required by FASB ASC Topic 820, Fair Value Measurement and Disclosure (“ASC 820”). As of June 30, 2022, the Company recorded 13 swap transactions with clients having a total notional amount of $54.8 million, offset by 13 swap transactions with dealers having a total notional amount of $54.8 million. Additionally, we recorded $0.1 million in back-to-back swap fee income for the six months ended June 30, 2022. The fair value of these derivatives is based on a market standard discounted cash flow approach. The Company incorporates credit value adjustments on derivatives to properly reflect the respective counterparty’s nonperformance risk in the fair value measurements of its derivatives. As of June 30, 2022, the Bank’s asset fair value position in other assets was $3.9 million and liability fair value position in other liabilities was $3.9 million, and were fully collateralized with pledged securities held with the counterparty in excess of the exposure amount at quarter end.

NOTE 11 — LOAN COMMITMENTS AND OTHER RELATED ACTIVITIES

Some financial instruments, such as loan commitments, credit lines, letters of credit, and overdraft protection, are issued to meet customer financing needs. These are agreements to provide credit or to support the credit of others, as long as conditions established in the contract are met, and usually have expiration dates. Commitments may expire without being used. Off-balance-sheet risk to credit loss exists up to the face amount of these instruments, although material losses are not anticipated. The same credit policies are used to make such commitments as are used for loans, including obtaining collateral at exercise of the commitment.

On April 8, 2021, the Company formed a separately capitalized subsidiary, Pro Opp Fund LLC. Subsequent to June 30, 2022, Pro Opp Fund LLC committed to investments of approximately $0.9 million in businesses directly, and indirectly related to the Company’s core business as permitted under the U.S. Bank Holding Company Act. Pro Opp Fund LLC has an additional $0.8 million of unfunded investments outstanding.

The contractual amounts of financial instruments with off-balance-sheet risk on June 30, 2022, and December 31, 2021, were as follows:

(Dollars in thousands)	June 30, 2022			December 31, 2021
Available lines of credit	​	$	471,356	​	$	415,402
Unfunded loan commitments – fixed	​	​	34,058	​	​	62,126
Unfunded loan commitments – variable	​	​	73,081	​	​	46,698
Standby letters of credit	​	​	11,974	​	​	12,095
Commercial letters of credit	​	​	3,664	​	​	2,765
Total credit extension commitments	​	$	594,133	​	$	539,086

NOTE 12 — REGULATORY CAPITAL MATTERS

Banks and bank holding companies are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance-sheet items

D-65

calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate regulatory action. Under the Basel Committee on Banking Supervision’s capital guidelines for United States banks (Basel III rules), the Bank must hold a capital conservation buffer above the adequately capitalized risk-based capital ratios. The capital conservation buffer for 2022 and 2021 was 2.50%. The Company opted not to include net unrealized gains or losses on available for sale securities in computing regulatory capital. As of June 30, 2022, the Bank met all capital adequacy requirements to which it was subject.

Prompt corrective action regulations provide five classifications: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized, although these terms are not used to represent overall financial condition. If adequately capitalized, regulatory approval is required to accept brokered deposits. If undercapitalized, capital distributions are limited, as is asset growth and expansion, and capital restoration plans are required. On June 30, 2022, and December 31, 2021, the most recent regulatory notifications categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes have changed the institution’s category. Based on changes to the Federal Reserve’s definition of a “Small Bank Holding Company” that increased the threshold to $3 billion in assets in August 2018, the Company is not currently subject to separate minimum capital measurements. At such time as the Company reaches the $3 billion asset level, it will again be subject to capital measurements independent of the Bank. For comparison purposes, the Company’s ratios are included in following discussion as well, all of which would have exceeded the “well-capitalized” level had the Company been subject to separate capital minimums.

Actual and required capital amounts and ratios are presented below on June 30, 2022, and December 31, 2021. The required amounts for capital adequacy shown below do not include the capital conservation buffer previously discussed.

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.

(c)   Opinion of Financial Advisors

Furnished as Appendix B and Appendix C 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

II-3

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.

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.
