PROXY STATEMENT 2023

SHAREHOLDER LETTER

Charles M. Shaffer

Chairman and
Chief Executive Officer

To our fellow shareholders, customers, partners and friends:

2022 was a year of growth and achievement at Seacoast. We strengthened our competitive position and drove significant market expansion across the state of Florida through both organic growth and acquisitions. We significantly improved the digital experience for our customers with a digital conversion that added new features and functionality. We enhanced our commercial banking team, recruiting seasoned bankers, treasury officers, and credit officers, and achieved another record-breaking year in wealth management. All this while making significant investments in talent and technology to scale our operational areas as we become a mid-size bank.

We began the year completing the acquisitions of Sabal Palm Bank and Florida Business Bank. We entered Naples and Jacksonville with de novo teams, resulting in better-than-expected growth in both markets. In October, we completed the acquisition of Drummond Community Bank, expanding our presence in North Florida including Ocala and Gainesville. Also in October, we acquired Apollo Bank, taking Seacoast into Miami-Dade County. With the acquisition in January 2023 of Professional Bank, we further increased our reach in South Florida.

We continued to maintain a fortress balance sheet, and financial results were strong. Our longstanding focus on relationship-based community banking results in a diversified base of customers across a wide variety of industries. We maintain capital levels that are well in excess of bank regulatory requirements and are among the highest of banks across the industry of any size, providing long term stability for our customers and communities.

Other 2022 highlights include:

| ● | Net interest income increased $90.1 million, or 33%, to $366.7 million, and net interest margin (on a fully tax equivalent basis)1 increased to 3.69% in 2022 from 3.27% in 2021.

| ● | Cost of deposits, supported by Seacoast’s longstanding relationship-based approach, remained low at 11 basis points in 2022 compared to 8 basis points in 2021.

| ● | Transaction accounts increased 29 percent year over year and at December 31, 2022, represented 64 percent of overall deposit funding.

| ● | Net income was $106.5 million, with pre-tax pre-provision earnings1 increasing 10% to $164.8 million. On an adjusted basis, which excludes direct merger-related costs, pre-tax pre-provision earnings1 increased 24% to $203.8 million.

| ● | Tangible common equity to tangible assets of 9.1% and peer-leading capital levels support Seacoast's continued achievement of strategic growth initiatives. Our ratio places us among the top quartile of banks across the industry.

| ● | Achieved organic loan growth of 9% while maintaining strict credit underwriting standards and broad distribution amongst industries and collateral types. Including acquisitions, loans grew to $8.1 billion at December 31, 2022, an increase of $2.2 billion, or 37 percent, from December 31, 2021.

| ● | Portfolio diversification, in terms of asset mix, industry, and loan type, has been a critical element of the Company's lending strategy. Exposure across industries and collateral types is broadly distributed. We continue to be vigilant in maintaining our disciplined, conservative credit culture.

| ● | Continued strong asset quality trends, with nonperforming loans representing 0.35% of total loans at December 31, 2022.

| ● | While the Florida economy continues to demonstrate strength, we maintain a cautious view of the overall economic outlook and a prudent level of reserves for potential credit losses. Our allowance for credit losses stands at 1.4% of total loans, and additional loss absorption capacity of 1.2% of total loans was recorded in connection with recently acquired banks.

| ● | For the third consecutive year, Seacoast Bank was named one of the Best Banks to Work For in 2022 by American Banker. This award identifies, recognizes and honors U.S. banks for outstanding employee satisfaction and engagement.

Thank you to all Seacoast associates for your hard work and effort in 2022 – it was truly a special and transformative year for our company.

Seacoast’s balanced growth strategy, combining organic growth with value-creating acquisitions on a strong capital base, continues to benefit shareholders and expand the franchise across Florida. Our peer-leading capital level, prudent credit culture, carefully underwritten loan portfolio, and high-quality customer franchise, paired with one of the strongest balance sheets in the industry, allow us to weather possible macroeconomic challenges ahead as we continue to build Florida’s leading community bank.

SEACOAST BANKING CORPORATION OF FLORIDA

Execution of our balanced growth strategy in 2022 produced strong results year over year:

Seacoast continued to drive positive momentum in performance metrics, while continuing to protect and prudently grow capital. For the year ended December 31, 2022, the Company reported $106.5 million in net income, or $1.66 per share. Net revenue for the same period was $432.3 million, an increase of 25% year-over-year.

PROXY STATEMENT 2023

Executive Compensation Program Highlights

The Compensation and Governance Committee (“CGC”) is committed to aligning our compensation strategies with our evolving business strategy, good governance and effective risk management practices, and our efforts to generate superior long-term returns for our shareholders. To this end, we emphasize pay-for-performance in executive compensation programs. Our executive compensation strategy strongly aligns our CEO and other executives’ pay with long-term shareholder interests. The CGC uses a peer group analysis to inform its design of the compensation structure and its compensation decisions. The following table summarizes the primary elements of our executive compensation for 2022:

Pay Element | Purpose | Determination | 2022 Results
Base Salary | Recognize performance of job responsibilities, and attract and retain individuals with superior talent. | Reflects the CGC’s assessment of the executive’s experience, skills and value to Seacoast. | Salary changes for our NEOs in 2022 were made largely to reflect additional duties and responsibilities. Mr. Shaffer’s base salary increased by 20% in 2022 in recognition of his appointment to Chairman of the Board effective February 3, 2022 and the Company’s transition to a mid-size bank. Ms. Dexter’s salary increased 7% in recognition of her expanded responsibilities over the Company’s general services and facilities teams. Salary increases for the remaining NEOs were 4% or less.
Annual Cash Bonus | Recognize achievement of our short- term business strategy objectives and individual executive performance. Incorporates both quantitative and qualitative goals. | Reflects the individual executive’s performance against pre-established individual goals, as well as relative bank performance. In FY2022, these goals included performance relative to peer performance of return on tangible common equity, earnings per share growth, pre-tax pre-provision net revenue growth and annual budgeted EPS. Qualitative goals were primarily related to achieving the Company’s long-term strategic objectives. The final amount is determined by the CGC’s qualitative assessment of overall performance. | Individual and Company performance were evaluated in Q1 2023, with corresponding payout determinations approved in March 2023, reflecting Company performance in 2022, as well as subjective adjustments based on the achievement of individual goals and performance.
Performance Stock Units (“PSUs”) | Align compensation with our business strategy and long-term shareholder value while providing a strong retention element. | The number of PSUs granted is determined by the CGC after consideration of each executive’s performance scorecard for the prior year. The number of PSUs that may be earned is based on the level of achievement of goals established by the CGC for a three-year performance period. In addition, PSUs only vest upon completion of a one-year continued service requirement following the close of the performance period. Value realized upon vesting varies based on stock price performance at the vesting date. | PSUs granted in 2022 vest based on the level of achievement of goals relating to average annual EPS growth and average annual return on average tangible common equity over a three- year period (2022-2024) relative to a peer group. PSUs for which performance goals are met will vest on December 31, 2025, subject to the grantee’s continued service.
Restricted Stock Awards (“RSAs”) | Provide a strong retention element and align executive and shareholder interests. | The amount of RSAs granted is determined by the CGC after consideration of each executive’s performance scorecard for the prior year. The realized value of RSAs is based on stock price performance at the vesting date. | RSAs granted in 2022 vest in equal annual installments over three years.

Please refer to the Compensation Discussion and Analysis and The Executive Compensation Tables in this proxy statement for additional details about our compensation programs.

Our Director Nominees

You are being asked, among other proposals, to elect three Class III directors of Seacoast. All of the nominees are presently directors of Seacoast. All of the nominees also serve as members of the board of directors of Seacoast’s principal banking subsidiary, Seacoast National Bank (the “Bank”). If elected, each director nominee will serve a three-year term expiring at the 2026 Annual Meeting and until their successors have been elected and qualified. Detailed information about each nominee’s background, skills and expertise can be found in Proposal I – Election of Directors

Alvaro J. Monserrat | 54 | 2017 | Independent advisor of business strategy and execution for CEOs of technology start-up companies | ✓ | 0

Director Nomination Process

The CGC serves as the Company’s nominating committee. The committee annually reviews and makes recommendations to the full Board of Directors regarding the composition and size of the Board of Directors and its committees, and if determined necessary, recommends potential candidates to the Board for nomination for election to the Board by the Company’s shareholders. The CGC’s goal is to ensure that the Board of Directors consists of a diverse group of members with the relevant expertise, skills, personal attributes and professional backgrounds who, individually and collectively, are appropriate to achieve the Company’s strategic vision and business objectives, and best serve the Company’s and shareholders’ long-term interests.

As part of the assessment process, the CGC evaluates whether the addition of a director or directors with particular attributes, experience, or skill sets could enhance the Board’s effectiveness. The CGC identifies director candidates through business, civic and legal contacts, and may consult with other directors and senior officers of the Company. The CGC may also utilize a search firm to help it identify, evaluate and conduct due diligence on potential director candidates. Once a candidate has been identified, the CGC confirms that the candidate meets the minimum qualifications for director nominees, and gathers information about the candidate through interviews, questionnaires, background checks, or any other means that the CGC deems to be helpful in the evaluation process. Director candidates are interviewed by the Chair of the CGC and at least one other member of the committee. Each member of the committee participates in the review and discussion of director candidates. Where appropriate, directors who are not on the CGC are encouraged to meet with and evaluate the suitability of potential candidates. The CGC then evaluates the qualities and skills of each candidate, both on an individual basis and taking into account the overall composition and needs of the Board in relation to the Company’s strategic goals, and recommends nominees to the Board. The full Board formally nominates candidates to be included in the slate of directors presented for shareholder vote based upon the recommendations of the CGC following this process.

5

PROXY STATEMENT 2023

Given the evolving needs and business strategy of the Company, the CGC believes that the Board of Directors as a whole should have diversity of thought and experience, which may, at any one or more times, include differences with respect to personal, educational or professional experience, gender, ethnicity, national origin, geographic representation, community involvement and age. However, the CGC does not assign specific weights to any particular criteria. Its goal is to identify nominees that, considered as a group, will possess the talents and characteristics necessary for the Board of Directors to fulfill its responsibilities and advance the Company’s strategic mission. In addition, each director must have the qualifications set forth in the Company’s Bylaws, as well as the personal characteristics and core competencies described below as Director Eligibility Guidelines:

Director Eligibility Guidelines
Personal Characteristics | Core Competencies
● the highest ethical character ● a personal and professional reputation consistent with Seacoast’s values as reflected in its Code of Conduct ● the ability to exercise sound business judgment ● a willingness to listen to differing points of view and work in a mutually respectful manner | ● substantial business or professional experience and ability to offer meaningful advice and guidance to the Company’s management based on that experience ● professional achievement through service as a principal executive of a major company, partner in a law or accounting firm, successful entrepreneur, prominent academic or similar position of significant responsibility

The CGC also considers numerous other qualities, skills and characteristics when evaluating director nominees, such as a candidate’s:

| ● | understanding of and experience in the financial services industry, as well as accounting, finance, legal, real estate, corporate governance and technology expertise;

| ● | leadership experience with public companies or other major organizations, as well as civic and community relationships;

| ● | availability and commitment to carry out the responsibilities as a director;

| ● | knowledge, experience and skills that enhance the mix of the Board’s core competencies and provide a different perspective;

| ● | the absence of any real or perceived conflict of interest that would impair the director’s ability to act in the best interest of shareholders; and

| ● | qualification as an independent director.

In addition to nominations by the CGC, any Company shareholder entitled to vote generally on the election of directors may recommend a candidate for nomination as a director by providing advance notice of such proposed nomination to the Corporate Secretary at the Company’s principal offices at 815 Colorado Avenue, Stuart, Florida 34994. The written submission must comply with the applicable provisions in the Company’s Articles of Incorporation. To be considered, recommendations with respect to nominees for election as directors at an annual meeting must be received not less than 60 days nor more than 90 days prior to the anniversary of the Company’s last annual meeting of shareholders (or, if the date of the annual meeting is changed by more than 20 days from such anniversary date, within 10 days after the date that the Company mails or otherwise gives notice of the date of the annual meeting to shareholders), and recommendations with respect to the election of directors to be held at a special meeting called for that purpose must be received by the 10th day following the date on which notice of the special meeting was first mailed to shareholders. Recommendations meeting these requirements will be brought to the attention of the Company’s CGC. Candidates for director recommended by shareholders in compliance with these provisions and who satisfy the Director Eligibility Guidelines will be afforded the same consideration as candidates for director identified by Company directors, executive officers or search firms, if any, employed by the Company. For our 2023 Shareholder Meeting, no shareholder director nominee recommendations were received.

Board Responsiveness

The Company includes in its proxy statement a separate advisory vote on the compensation paid to its executives, as disclosed in the Compensation Discussion and Analysis, the compensation tables and related proxy disclosure, commonly known as a “say-on-pay” proposal. Independent surveys have shown that an annual vote is the preferred frequency of most institutional investors. Our shareholders also have expressed a preference for an annual vote. Our Board also endorses an annual vote as we believe it gives shareholders an opportunity to voice their concerns with respect to executive compensation. Shareholder support of our say-on-pay proposal at our 2022 annual meeting was strong. (See “Outcome of our 2022 Say-On-Pay vote” in the table below.) Overall shareholder support of directors standing for election at the 2022 annual meeting was comparable to the prior year. Below are highlights of the feedback we have received from shareholders and our Board’s response:

What We Heard | Our Board’s Response
Continue to deliver industry-leading financial results | Delivered 2022 net income of $106.5 million, with pre-tax pre-provision earnings1 increasing 10% to $164.8 million. On an adjusted basis, which excludes direct merger-related costs, pre-tax pre-provision earnings1 increased 24% to $203.8 million.
Distribute capital to shareholders | In 2022, Seacoast increased the quarterly cash dividend to $0.17 per share.
Continue to emphasize stock ownership by management and directors | We emphasize stock compensation with PSUs and RSAs granted under the long-term incentive plan (“LTIP”) to executive officers for achievement of performance objectives in 2022. All of our directors are paid a stock retainer; some defer a portion or all of their cash compensation into our director deferred compensation plan. Our executive officers and directors are also subject to our stock ownership guidelines, which require them to retain a number of shares of our stock.

SEACOAST BANKING CORPORATION OF FLORIDA

What We Heard | Our Board’s Response
Outcome of our 2022 Say-On-Pay vote | At our 2022 annual meeting of shareholders, our say-on-pay proposal received the support of 91.5% of the votes cast. Our CGC considered the vote in relation to: 1) the alignment of our compensation program with the long-term interests of our shareholders, 2) the transition to a mid-size bank and aligned business strategy with emerging opportunities of M&A and fulfilling customer demand for products and services, and 3) the relationship between risk-taking and the incentive compensation provided to our executives. The CGC will continue to evaluate and refine our executive compensation programs and welcomes input from our shareholders.
Continued Environmental, Social and Governance (“ESG”) efforts and corporate sustainability opportunities | Information about the Company’s ESG initiatives and corporate sustainability oversight is enhanced in this 2023 proxy statement. In 2022, we updated our sustainability page on our corporate website to provide additional visibility to the Company’s ESG efforts. The Company’s corporate sustainability page can be viewed at: https://www.seacoastbanking.com/corporate-information/sustainability/default.aspx.

The Company’s Corporate Governance Guidelines provide for a process by which shareholders may communicate with the Board, a Board committee or the non-management directors as a group, or other individual directors. Shareholders who wish to communicate with the Board of Directors, a Board committee, the Lead Independent Director, other directors or an individual director may do so by sending written communications addressed to the Board of Directors, a Board committee or such group of directors or individual director, c/o Corporate Secretary, Seacoast Banking Corporation of Florida, 815 Colorado Avenue, P.O. Box 9012, Stuart, Florida 34995. All communications will be compiled by the Company’s Secretary and submitted to the Board of Directors, a committee of the Board of Directors or the group of directors or individual director, as appropriate, at the next regular meeting of the Board.

Board and Governance Highlights

Board Composition

In the past years, we have refreshed our Board with new talent to increase diversity and experience to better align overall Board capability with our strategic objectives. Since 2013, we have added seven new directors with strong skill sets to help achieve our growth initiatives. As a result, our overall Board composition has been enhanced across several important aspects creating a vibrant Board culture focused on creating shareholder value over the long term. Seacoast continues to build a diverse Board with experience aligned with our strategic mission to ensure a balanced mix of directors with a deep knowledge of Seacoast and its markets, as well as new members with fresh perspectives. The CGC members generally conceptualize diversity to include without limitation concepts such as race, gender, national origin, differences of viewpoints, education, work experiences, professional skills and other qualities or attributes that contribute to Board heterogeneity when identifying and recommending director nominees.

CORPORATE GOVERNANCE AT SEACOAST

Our goal is to maintain a corporate governance framework that supports an engaged, independent board with diverse perspectives and judgment that is committed to representing the long-term interests of our shareholders. We believe our directors should possess the highest personal and professional standards for ethics, integrity and values, as well as practical wisdom and mature judgment. Therefore, our Board, with the assistance of management and the CGC, regularly reviews our corporate governance principles and practices.

The Board’s Role in Strategy and Risk Oversight

The Board of Directors actively reviews our long-term strategy and the plans and programs that management develops to implement our strategy. While the Board meets formally at least once every year to consider overall long-term strategy, it generally reviews various elements of strategy, and our progress towards implementation thereof, at every regular meeting. Our directors are actively engaged in our strategic planning process and exercise robust oversight while challenging our strategies and implementation of such strategies.

The Board believes that strategic risk is an exceptionally important risk element among a number of risks that the Company faces. As a result, our Board works to ensure that this risk is appropriately managed in the context of the rapidly changing environment in which the Company and its customers operate. The Board does not believe this risk can be delegated and the Board as a whole regularly spends a significant amount of its time engaged with management and in executive session discussing our long-term strategies, the effectiveness of our plans to implement such strategies, and our progress against those plans.

The Board believes that an integral part of managing strategic risk is ensuring that the Board’s views are considered as our strategy evolves. The Board strongly believes that having active and engaged committee chairs and a lead independent director better ensures that the Board as a whole can serve as a credible challenge to management’s plans and programs and increases transparency.

The Board’s committees also work to ensure that we have the right alignment to support our long-term strategic direction including: (i) an active Board recruitment process focused on developing or acquiring the skill, experience and attributes of both individuals and the Board as a whole needed to support our strategy, (ii) ensuring an appropriate link is established between our compensation design and our long-term strategy to encourage and reward the achievement of our long-term goals and protect shareholder value by discouraging excessive risk taking, and (iii) ensuring that our risk management structure can effectively manage the inherent risks that underlie our strategy.

Other types of risks that the Company faces include:

| ● | macro-economic risks, such as inflation, interest rate fluctuations, reductions in economic growth, or recession;

| ● | political or regulatory risks, such as restriction on access to markets;

| ● | event risks, such as global pandemics, including COVID-19, natural disasters, acts of war or terrorism or cybersecurity breaches; and

| ● | business-specific risks related to financial reporting, credit, asset/liability management, market, operational execution (corporate governance, legal and regulatory compliance), and reputation (both of the Company and the financial services industry generally).

Our Enterprise Risk Management Committee (“ERMC”) of the Board of Directors regularly assesses our overall risk profile and oversees our risk management programs, which are implemented by our chief risk officer. Information security is a significant operational risk for financial institutions, and includes the risk of losses resulting from cyber-attacks. Our Board recognizes the importance of maintaining the trust and confidence of our customers, clients, and employees, and information security risk. In light of these risks, the ERMC reviews our data privacy and information security policies and practices on an annual basis. Additionally, the Board assesses the risks and changes in the cyber environment through presentations and reports provided to our ERMC, including participation in annual cyber security education and training.

Environmental, Social and Governance (“ESG”)

Our Board recognizes the importance of operating in a responsible and sustainable manner aligned with our mission, vision and values. Our Compensation and Governance Committee (“CGC”) of the Board is charged with monitoring ESG efforts, and identifies and discusses ESG issues material to our business and communities where we operate. We consider feedback from investors, employees, regulators, customers and other stakeholders on ESG topics. A key focus of our long-term strategic plan is managing growth through an evolving risk view, in which attention to ESG matters is critical to success.

The Company also aims to accommodate the banking and credit needs of our communities by providing various product offerings and community outreach and engagement. We are committed to building and encouraging an inclusive environment where all our employees and clients are respected and accepted for who they are. The Company provides equal employment opportunities in all facets of employment from the hiring and onboarding experience to compensation, benefits and prospects for career advancement and guidance.

The Board and senior management are committed to continuing to build upon these efforts in the coming years. You may view additional information about the Company’s corporate sustainability and ESG activities on our investor relations website located at www.SeacoastBanking.com.

Data Privacy and Information Security

Seacoast is committed to protecting our customers’ personal and financial information. The Company has adopted a Data Privacy Policy and Information Security Policy that are reviewed by the Enterprise Risk Management Committee (ERMC) of the Board of Directors on an annual basis. Through an integrated enterprise risk management process, key risks, including those related to privacy and cybersecurity are reviewed and evaluated by the ERMC before they are reviewed by the full Board. We have also adopted an Online and Mobile Privacy Policy and Privacy Policy Statement to ensure compliance with requirements of the Gramm-Leach-Bliley Act.

Our Board recognizes the importance of maintaining the trust and confidence of our clients, employees and business partners. We strive to continuously assess and update our response to information security risks and changes in the cyber security landscape. Information security risks are identified using internal risk assessments, internal audits, regulatory exams and third-party testing. Identified risks are prioritized, tracked and managed with senior management oversight.

Our data security strategy includes a host of defense mechanisms that include, but are not limited to:

| ● | Policies and Procedures

| ● | Annual employee training, educational opportunities and regular associate communications

| ● | Third party program oversight

| ● | Encryption technologies; and

| ● | Incident response program

We provide our associates with ongoing training opportunities and educational resources to strengthen cybersecurity awareness, keep abreast of cyber environment trends and continue to build knowledge in safeguarding against potential security and fraud risks. Additionally, our information security team maintains awareness of trends and best practices by pursuing professional certifications and educational opportunities with industry experts and professional organizations.

Periodic penetration tests are performed by independent third parties and are audited by an external firm with expertise in information security. During 2022, we did not experience a material compromise to any of our data systems or vendor platforms, and did not incur any expenses resulting from information security breaches, penalties or settlements. Should an information security incident occur, we have resources to assist with forensic analysis, response strategies and crisis communications.

Board Oversight of Strategy and Risk

Our Board has ultimate oversight responsibility for strategy and risk management, and directly advises management on development and execution of the Company’s strategy. Oversight is also provided through the extensive work of the Board’s committees – Audit Committee; Compensation and Governance Committee; Corporate Development Committee; and Enterprise Risk Management Committee – in key areas such as financial reporting, internal controls, compliance, corporate governance, compensation programs, capital planning and risk management. The ERMC oversees the integration of risk management at Seacoast, monitors the risk framework and makes recommendations to the Board regarding the Company’s risk appetite. Additionally, the Compensation and Governance Committee oversees risks and exposures related to the Company’s corporate governance, director succession planning, and compensation practices to ensure that they do not encourage imprudent or excessive risk-taking.

Board Composition

Seacoast continues to build a diverse Board with experience aligned with our strategic mission to ensure a balanced mix of directors with a deep knowledge of Seacoast and its markets, as well as new members with fresh perspectives. Our Board consists of all independent Board members, with the exception of two directors, including one executive director. All members of the Audit Committee and Compensation and Governance Committee of the Board and the Chair of the Enterprise Risk Management Committee are independent directors. Women account for 27% of the Board of Directors, including our Compensation and Governance Committee Chair. To further strengthen our corporate governance, our independent directors annually select a Lead Independent Director who chairs regularly scheduled executive sessions, without management present.

Our Corporate Governance Guidelines require that a substantial majority of the Board be composed of independent directors. In accordance with those guidelines, non-employee directors must advise the Chairman of the Board or Chair of the Compensation and Governance Committee in advance of accepting membership on any other public company board and before accepting membership on the audit committee or compensation committee of any other public company board. Employee Directors may serve on no other boards of public companies, unless otherwise approved by the Compensation and Governance Committee.

Shareholder Engagement

The Company engages with our shareholders to ensure that the Board and management are aware of and address issues of importance to our investors. We regularly meet with various institutional shareholders and welcome feedback from other shareholders, which is considered by the Board or appropriate Board committee. In 2022, management met with approximately 50 institutional shareholders, representing over 15% of the company’s ownership at December 31, 2022.

Corporate Governance Principles and Practices

Board Independence

The Company’s common stock is listed on the Nasdaq Global Select Market (“Nasdaq”) under the symbol “SBCF”. Nasdaq requires that a majority of the Company’s directors be “independent,” as defined by the Nasdaq rules. Generally, a director does not qualify as an independent director if the director (or, in some cases, a member of the director’s immediate family) has, or in the past three years had, certain relationships or affiliations with the Company, its external or internal auditors, or other companies that do business with the Company. The Board of Directors has determined that a majority of the Company’s directors are independent directors under the Nasdaq rules. The Company’s independent directors in 2022 were: Dennis J. Arczynski, Jacqueline L. Bradley, H. Gilbert Culbreth, Jr., Julie H. Daum, Christopher E. Fogal, Maryann Goebel, Robert J. Lipstein, Alvaro J. Monserrat and Thomas E. Rossin. Our governance principles provide that a substantial majority of our directors will meet the criteria for independence required by Nasdaq. Over 80% of our Board meets Nasdaq’s criteria for independence.

Board Evaluation Process

Periodically, our Board and each Board committee evaluate their performance and effectiveness, along with processes and structure, to identify areas for enhancement. The process is described below.

Element | Description
Corporate Governance Review and Investor Feedback | The CGC reviews corporate governance principles with consideration given to generally accepted practices and feedback from investors and makes recommendations for Board changes. This committee also oversees the process for annual board evaluations.
Annual Board & Committee Self-Evaluations | In 2022, Board and committee evaluations were individually conducted to assess the effectiveness of the Board and committees of the Board.
Summary and Review | For the 2022 Board and committee evaluations, responses were compiled and summarized, including comments, which were reviewed by the Chairman and Lead Independent Director, and who together presented summary results to the full Board. The committee evaluations were reviewed by the respective committee chairs, who then discussed the results with their respective committees and the full Board.
Actions | As a result of the Board evaluation process, the Board gained insight as to governance structure and committee rotation opportunities, and process improvements to facilitate broader engagement with discussion around emerging trends and cultural and inclusion matters.

Board Leadership Structure

The Board leadership framework is provided through: 1) Chairman and CEO Shaffer’s guidance and deep understanding of the financial services industry, 2) a clearly defined lead independent director role, 3) active committees and committee chairs, and 4) talented directors who are committed and independent-minded. At this time, the Board believes this governance structure is appropriate and best serves the interests of our shareholders and other stakeholders.

Lead Independent Director

To further strengthen our corporate governance, our independent directors annually select a Lead Director from the independent directors. Our Board believes that the Lead Director serves an important corporate governance function by providing separate leadership for the non-management and independent directors. In January 2023, the Board re-elected Christopher E. Fogal to serve as Lead Independent Director.

Non-Management Executive Sessions

In order to give a significant voice to our non-management directors, our Corporate Governance Guidelines provide for executive sessions of our non-management and independent directors. Our Board believes this is an important governance practice that enables the Board to discuss matters without management present.

Our non-management directors are given the opportunity to meet in executive session following each regularly scheduled Board meeting. Our independent directors meet separately from the other directors in regularly scheduled executive sessions at least twice annually, and at such other times as may be deemed appropriate by the Company’s independent directors. Our Lead Independent Director presides at all executive sessions of the independent directors and non-management directors, and sets the agenda for such executive sessions. Any independent director may call an executive session of independent directors at any time. The independent directors met two times in executive session in 2022.

13

PROXY STATEMENT 2023

Management Succession Planning and Development

Our Board understands that a strong succession framework reduces Company risk and therefore ensures that appropriate attention is given to identify and develop talented leaders. Consequently, we have a robust management succession and development plan which is reviewed annually and updated accordingly. The Board maintains oversight responsibility for succession planning with respect to the position of CEO and monitors and advises management regarding succession planning for other executive officers. The Board’s goal is to have a long-term and continuing program for effective senior leadership development and succession. The Board also has short-term contingency plans in place for emergency and unexpected occurrences, such as the sudden departure, death, or disability of our CEO or other executive officers.

The CGC, working with the CEO, annually evaluates succession planning at the senior levels of management and reports the results of such evaluation to the Board, along with recommendations on management development and succession planning. The updated succession plan is reviewed and approved by the Board to ensure that competencies are in alignment with our overall strategic plan. The annual review of the CEO succession plan includes a review of specific individuals identified as active CEO succession candidates, and each of those individuals is reviewed with respect to progress in his or her current job position and progress toward meeting his or her defined leadership development plan. The Company’s CEO and senior management are similarly responsible for supporting “next generation” leadership development by: identifying core talent, skills and capabilities of future leaders within the Company; assessing the individuals against leadership capabilities; identifying talent and skill gaps and development needs; assisting with internal candidate development; and identifying significant external hiring needs.

The Board and individual Board members may advise, meet with, and assist CEO succession candidates and become familiar with other senior and future leaders within the Company. Directors are encouraged to become sufficiently familiar with the Company’s executive officers to be able to provide perspective on the experience, capabilities and performance of potential CEO candidates. The Board encourages senior management, as well as other members of management who have future leadership potential within the Company, to attend and present at Board meetings so that each can be given appropriate exposure to the Board. The Board may contact and meet with any employee of the Company at any time, and are encouraged to make site visits, to meet with management, and to attend Company, industry and other events.

Committee Structure

Oversight is also provided through the extensive work of the Board’s committees – Audit Committee; Compensation and Governance Committee (“CGC”); Corporate Development Committee (“CDC”); and Enterprise Risk Management Committee (“ERMC”) – in key areas such as financial reporting, internal controls, compliance, corporate governance, succession planning, compensation programs, capital planning, cybersecurity and risk management. The Audit Committee and the CGC consist entirely of independent, non-management directors.

In addition, each year, the Board and each of its committees review a schedule of agenda topics to be considered in the coming year. Each Board and committee member may raise subjects that are not on the agenda at any meeting and suggest items for inclusion in future agendas. The Company believes that the foregoing structure, policies, and practices, when combined with the Company’s other governance policies and procedures, provide appropriate opportunities for oversight, discussion, evaluation of decisions and direction from the Board of Directors.

AUDIT COMMITTEE REPORT

The Audit Committee is currently comprised of five directors: Dennis J. Arczynski, Christopher E. Fogal, Maryann Goebel, Robert J. Lipstein (Chair) and Alvaro J. Monserrat.

The purpose of the Audit Committee (the “Committee”) is to assist the Board of Directors (the “Board”) of Seacoast Banking Corporation of Florida (the “Company”) in its general oversight of the Company’s accounting, auditing and financial reporting practices. Management is primarily responsible for the Company’s financial statements, systems of internal controls and compliance with applicable legal and regulatory requirements. The Company’s independent registered public accounting firm, Crowe LLP, for the year ended December 31, 2022 is responsible for performing an independent audit of the consolidated financial statements and expressing an opinion on the conformity of those financial statements with accounting principles generally accepted in the United States, as well as expressing an opinion (pursuant to Section 404 of the Sarbanes-Oxley Act of 2002) on the effectiveness of internal control over financial reporting.

The members of the Committee are not professional auditors, and their functions are not intended to duplicate or to certify the activities of management and the independent registered public accounting firm, nor can the Committee certify that the Company’s registered public accounting firm is “independent” under applicable rules. The Committee serves a board-level oversight role, in which it provides advice, counsel and direction to management and the independent registered public accounting firm on the basis of the information it receives, discussions with management and the independent registered public accounting firm, and the experience of the Committee’s members in business, financial and accounting matters. To carry out its responsibilities, the Committee held eight meetings in 2022.

In the performance of its oversight responsibilities, the Committee has reviewed and discussed with management and Crowe LLP the audited financial statements of the Company for the year ended December 31, 2022. Management represented to the Committee that all financial statements were prepared in accordance with accounting principles generally accepted in the United States and that these statements fairly present the financial condition and results of operations of the Company at the dates and for the periods described. The Committee has relied upon this representation without any independent verification, except for the work of Crowe LLP. The Committee also discussed these statements with Crowe LLP, both with and without management present, and has relied upon their reported opinion on these financial statements. The Committee’s review included discussion with Crowe LLP of the matters required to be discussed under Public Company Accounting Oversight Board standards.

With respect to the Company’s independent registered public accounting firm, the Committee, among other things, discussed with Crowe LLP matters relating to its independence and received from Crowe LLP the written disclosures and the letter required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent accountant’s communications with the Committee concerning independence.

On the basis of these reviews and discussions, and subject to the limitations of its role, the Committee recommended that the Board approve the inclusion of the Company’s audited financial statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, for filing with the Securities and Exchange Commission.

EXECUTIVE COMPENSATION

COMPENSATION DISCUSSION & ANALYSIS

Executive Summary

2022 Performance Considerations

Our strategic plan for 2022 continued to focus on shareholder value creation, and the CGC used average annual earnings per share (“EPS”) growth and average annual return on average tangible common equity (“ROATE”) as key indicators that management is on the right path to produce sustainable long-term value. EPS provides a direct link to value creation at the shareholder level, and ROATE provides a measure of risk-adjusted returns that illustrates the health of the Company. The CGC determined the amount of annual and long-term incentives to award to our named executive officers (“NEOs”) for 2022 using a qualitative assessment of management’s performance in 2022 and 2021, respectively, taking into account both growth and returns with consideration given to our risk framework. The assessment process included scorecards that identified shared and individual goals for the year in the areas of operations, technology, risk, talent, and business transformation, with our average annual EPS growth and average annual ROATE serving as the primary considerations for long-term incentive awards granted in 2022. The number of long-term incentive awards granted in 2023 will be based on the scorecard assessment of performance in 2022.

Say on Pay Results

In 2022, our “Say on Pay” proposal received 91.5% support compared with 98.5% support in 2021; indicating plan design and governance are aligned with our shareholders. While our historical results indicate strong support for Seacoast’s NEO compensation, the CGC continues to review our executive compensation structure to increase its effectiveness and further align with shareholder interests in light of changing industry dynamics.

Our Executive Compensation Design Priorities and Prohibitions

Design Priorities (what we do) |  |  | Design Prohibitions (what we don’t do)
✔ Manage our executive compensation programs to have a strong pay-for-performance orientation. ✔ Link performance-based incentive awards to enterprise-wide and individual performance goals. ✔ Grant our NEOs equity-based awards based on Company and individual performance. ✔ Emphasize long-term stock-based awards in our executive compensation and total incentive strategies. ✔ Set meaningful performance goals that align management with shareholder interests. ✔ Require Tier 1 Capital compliance thresholds be met in order for any portion of the PSUs to vest. ✔ Ensure that incentives are sensitive to risk considerations. ✔ Provide minimal executive perquisites. ✔ Maintain executive stock ownership requirements, and require post-settlement holding periods or mandatory deferral of certain performance-based awards. ✔ Provide reasonable executive post-employment and change-in-control protections. ✔ Require “clawback” provisions for certain incentive-based compensation to ensure accountability. ✔ Engage with shareholders on their concerns or priorities for our director and executive compensation programs. |  |  | No repricing of stock options without shareholder approval. No incentives that encourage improper risk taking. No excise tax gross-ups upon a change in control. No single trigger vesting acceleration on unvested equity in connection with a change-in-control. No hedging, and limited pledging, of our common shares by our directors and executive officers.

PROXY STATEMENT 2023

2022 NEO Pay

| ● | Salary changes for our NEOs in 2022 were made largely to reflect the expansion in the duties and responsibilities associated with the growth of the Company. Cumulative base salary for Mr. Shaffer increased 20% in 2022 in connection with his additional duties as Chairman of the Board and the Company’s transition to a mid-size bank. Ms. Dexter’s salary increased 7% in recognition of her additional responsibilities of managing our general services and facilities teams and overseeing the corporate strategy of the Company in 2022. Salary increases for the remaining NEOs were 4% or less.

| ● | In 2022, our NEOs received short-term incentives based on Company performance for the year and the achievement of pre-established individual goals. Awards were also based on the ongoing achievement of the Company’s strategic plan.

| ● | In 2022, our NEOs received awards of Performance Share Units (“PSUs”) that vest based on the level of achievement of goals relating to average annual growth in EPS and average annual ROATE over a three-year period relative to the performance of a selected peer group. PSUs for which performance goals are met will vest in 2025, subject to the grantee’s continued service.

| ● | In 2022, our NEOs received awards of time-based Restricted Stock Awards (“RSAs”) that vest over a three-year period.

| ● | The number of PSUs and RSAs granted in 2022 was determined by the CGC based upon the scorecard assessment of 2021 performance. Any awards granted based upon 2022 scorecard performance will be granted in 2023.

Summary of Compensation Decisions in 2022

The CGC structures the compensation program for executive management with an emphasis on long-term performance-based compensation. For planning purposes, the CGC focuses on the sum of annual base salary, annual cash bonuses and the values it considers and approves for equity awards, which are granted in the subsequent year based on annual scorecard performance. We refer to this planning value as Total Direct Compensation or “TDC”. The CGC considered this TDC in its decision process when determining the value of the total incentive award value granted in 2022. The following chart illustrates the relative emphasis of each pay element in relation to TDC, as disclosed in our 2022 Summary Compensation Table (“SCT”),

2022 NEO Mix of Total Direct Compensation

In general, the CGC closely aligns the compensation of our executives with the creation of both short-term profitability and long-term value for our shareholders by structuring a substantial portion of TDC as “at risk” incentive pay. The CGC relies on this structure to ensure that annual cash bonuses are fully reflective of performance for the year in which they are earned and long-term incentive awards are fully reflective of performance for the year in which their target award values are determined.

Base Salary

All of our NEOs receive a base salary that reflects the CGC’s assessment of the NEO’s skills and value to Seacoast. It is the CGC’s philosophy to keep salaries within a competitive market range and increase base salaries in response to increases in the size, scope or complexity of an executive’s job, in connection with a promotion or other forms of recognition that appropriately reflect value considerations, or to maintain the desired level of internal relative value. For 2022, Mr. Shaffer’s base salary increased 20% in connection with his additional duties as Chairman of the Board and the Company’s transition to a mid-size bank, and Ms. Dexter’s base salary increased 7% in recognition of her additional responsibilities of managing our general services and facilities teams and overseeing the corporate strategy of the Company. Salary increases for the remaining NEOs were 4% or less. The 2022 annualized base salary actions for our NEOs are summarized in the following table.

Annual Cash Bonuses

Seacoast awarded annual cash bonuses to its NEOs in 2023 in recognition of the Company’s annual performance and individual annual performance of each NEO in 2022.

For 2022 annual cash bonuses, Seacoast established an annual incentive structure that includes both qualitative and quantitative components, reflecting the individual executive’s performance against pre-established individual goals as well as the Company’s performance in 2022 relative to peer performance for return on tangible common equity, EPS growth, pre-provision net revenue growth and Company budgeted EPS. Individual goals covered the implementation of specific qualitative goals related to the Company’s strategic plan objectives. Actual payout amounts were determined at the discretion of the CGC based on its qualitative assessment of overall performance, with input from the CEO for the other NEOs.

Equity Awards

Seacoast’s equity strategy aligns equity recipients with shareholder interests, supports our retention strategies, and elevates our visibility and appeal as an employer of choice for highly skilled talent. The following table summarizes the emphasis of our equity strategy for long-term growth.

Seacoast’s Equity Strategy

Grant Cycle | Type of Equity | Performance Period / Payout Range / Vesting Period | Performance Objective(s)
2022 (Apr.) | PSUs | ● 75% of LTI Award performance-based ● 3-year Performance Period, with additional service required through the end of the year following the Performance Period ● Payout as a % of Target (0-225%) | ● Relative Average Annual EPS Growth (50%) ● Relative Average Annual ROATE (50%) ● Tier 1 Capital Compliance
RSAs | ● 25% of LTI Award ● 3-year ratable vesting | ● Pay-for-performance as part of LTIP in recognition of overall performance in the prior year

23

PROXY STATEMENT 2023

2022 Performance Stock Unit (“PSU”) Awards

2022 PSUs represent stock-settled incentive awards where payout can vary from 0% to 225% of the target number of shares granted. One-half of the PSUs will be earned based on Seacoast’s three-year (2022-2024) average annual growth in EPS (“EPS PSUs”) relative to the peer group described under “Compensation Peer Group”. The remaining one-half of the PSUs will be earned based on Seacoast’s three-year (2022-2024) average annual return on average tangible common equity (“ROATE PSUs”) relative to the peer group. PSUs for which performance goals are met will vest on December 31, 2025, subject to the grantee’s continued service. The CGC selected EPS and ROATE given their importance in our strategic plan and significant influence on our stock price performance over sustained periods of time. In each case, the number of PSUs actually earned will be determined by our performance as compared to the peer group performance as approved by the CGC at the time of grant, subject to an absolute performance payout cap. PSU payouts will be capped at the target in the event that certain absolute EPS and ROATE hurdles are not met, irrespective of performance relative to the peer group. The PSUs also include a risk-based condition (meet or exceed minimum requirements for Tier 1 Regulatory Capital) that must be met in order for any portion of the awards to vest. Cash dividend or dividend equivalents on PSUs awarded to management are accrued from the grant date and paid only if and when the underlying units become vested and payable.

Time-Based Restricted Stock Awards (“RSA”)

Our pay-for-performance stock incentive strategy is balanced with the use of time-based RSAs to enhance holding power, retention and recruitment, while further aligning the interests of the executives and shareholders. The RSAs granted in 2022 were issued in recognition of 2021 performance, and vest ratably over a three-year period. Dividends may be payable subject to additional restrictions as determined by the CGC and reflected in the award agreement, or when the underlying shares are vested.

Overview of Executive Compensation

Role of the CGC

The CGC is responsible for establishing our compensation philosophy and for overseeing our executive compensation policies and programs generally. As part of this responsibility, the CGC:

| ● | regularly interacts with our executives in order to make informed decisions on performance, potential, developmental needs and their value to Seacoast;
| ● | approves our executive compensation programs, including construction of our peer group, issuance of equity awards, and certification of results;
| ● | evaluates the performance of the CEO and determines the CEO’s compensation;
| ● | reviews the performance of other members of executive management and their compensation adjustments proposed by the CEO; and
| ● | assesses our incentive strategies from a risk perspective, ensuring that earnings opportunities strike the right balance between risk and reward and that our executives are not motivated to take excessive risks.

Role and Independence of the Compensation Consultant

The CGC is comprised solely of independent directors and met seven times in 2022. The CGC engaged Alvarez and Marsal, LLC (“A&M”) as its independent compensation consultant to advise the CGC in 2022. A&M periodically attended CGC meetings, including executive sessions, and provided information and advice independent of management and, at the direction of the CGC Chair, assisted management with various activities that support Seacoast’s executive compensation program. The CGC evaluated these considerations pursuant to SEC and NASDAQ rules and concluded that the engagement of A&M, and the services it provided did not raise any conflict of interest.

24

SEACOAST BANKING CORPORATION OF FLORIDA

Compensation Peer Group

The CGC relies on market pay data and related research to inform its decision on the construction and expected outcomes of our director and executive compensation programs. In considering peer group construction, the CGC recognizes that Seacoast competes for executive talent against a wide variety of financial services organizations that rely on or want to acquire the skill sets that our executives offer. As a result, the CGC relies substantially on information developed from a size-appropriate, high-performing core bank industry compensation peer group in its decision process. In terms of assessing the effect of the CGC’s decisions on how we position pay vis-à-vis market, we rely exclusively on pay and performance data developed using our core bank industry compensation peer group or, as needed, from the McLagan Regional Bank Survey. The CGC does not identify a specific target level or percentile of base salary, incentive cash, or stock-based awards for our NEOs. Instead, pay outcomes, which include the target value of stock awards to be earned for future performance, initially are determined by internal performance and talent considerations. The CGC then compares contemplated NEO pay actions against market pay levels for reasonableness with the market assessments serving as key points of reference and validation in the CGC’s process.

In 2022, the peer group was selected from comparable publicly-traded banks with market capitalizations between $1-$6 billion and total assets $5 billion or more. This determination reflects the CGC’s desire to incorporate an important relative performance dimension that is critical to our efforts to continue to grow the value of Seacoast. The CGC sees this approach as appropriate given its expectations for performance and growth.

The CGC reviews the peer group annually to ensure continued appropriateness, and makes changes when it believes warranted. In 2022, the CGC removed BancorpSouth Bank, due to its acquisition during the year, and added two banks, ConnectOne Bancorp and Veritex Holdings, to the prior year’s peer group. Our 2022 Peer Group was comprised of:

2022 PEER GROUP
Ameris Bancorp (ABCB) | FB Financial Corp.(FBK) | ServisFirst Bankshares (SFBS)
Atlantic Union Bankshares (AUB) | First BanCorp (FBNC) | Simmons First National (SFNC)

2022 EXECUTIVE COMPENSATION ACTIONS

The CGC and our CEO rely on quantitative and qualitative assessments of the performance of our NEOs and other members of the senior management team given our accelerated growth, the rapid evolution of business, and the changing demands on our executives. The assessment process utilizes scorecards that are approved at the start of each year, establishing performance guidelines against which results are compared at the end of the year. Performance ratings are then developed for each NEO, which are used to inform the CGC’s decision regarding pay actions. The CGC believes that qualitative assessments of NEO performance for the purpose of compensation, development and advancement continue to serve the best interests of our shareholders.

Our CEO works closely with the CGC in establishing executive compensation and overall bonus and incentive payments each year. The CEO evaluates the performance of each NEO and other senior executives, and, based on these performance evaluations, market compensation surveys, and other data, he will then make qualitative assessments and recommendations to the CGC. The CEO also presents incentive compensation payment recommendations for the CGC’s consideration. The CGC evaluates and makes a qualitative assessment of the CEO’s performance and determines his compensation without the CEO present.

The number of PSUs and RSAs granted in 2022 was determined based on 2021 performance scorecard evaluations. Equity awards relating to 2022 performance scorecard evaluations will be granted in 2023. Short-term cash incentives for 2022 were based on 2022 performance scorecard evaluations and will be paid in 2023.

Key Influences in Compensation Decisions

Performance Metrics

The components of our executive compensation program are intended to align with long-term shareholder value creation. Key performance considerations include the use of relative rather than absolute measures for performance metrics and an overall LTIP mix of 25% time-based RSAs and 75% performance-based PSUs split evenly between EPS and ROATE. One-half of the performance-based stock units granted in 2022 (the “EPS Growth Units”) are eligible to vest based on the Company’s Average Annual EPS Growth for the three-year performance period, relative to the average ratio of the peer group, and one-half of the performance-based stock units granted in 2022 (the “ROATE Units”) are eligible to vest based on the Company’s Average Annual ROATE for the same performance period, relative to the average ratio of the peer group. PSUs for which performance goals are met will vest one year following the performance period, subject to the grantee’s continued service.

Senior executives are also eligible to receive an annual cash bonus as a component of the executive compensation program based on individual goals and performance measurements. Overall, annual cash bonuses are calculated based on pre-established target goals, including Company performance in 2022 relative to peer group performance for return on tangible common equity, earnings per share growth and pre-provision net revenue growth, with payouts made in 2023 and determined by the CGC’s qualitative assessment of overall performance.

For 2022, senior executives were assessed on the following performance:

Component | What it Measures | Why it is Used
Long-Term Incentive
Average Annual EPS Growth | Earnings per share (EPS) is the portion of the Company’s profit allocated to each share of common stock. | A broadly used indicator of profitability, useful for tracking performance over time or in comparison to benchmarks.
Average Annual ROATE | Net income as a percentage of average shareholders’ equity, excluding intangible assets. | A broadly used indicator of effective utilization of capital, useful for tracking performance over time or in comparison to benchmarks.

Other Elements of the 2022 Compensation Program for Executive Officers

Change in Control Severance Benefits

We provide change in control severance benefits to the NEOs to encourage them to consider the best interests of shareholders by stabilizing any concerns about their own personal financial well-being in the face of a potential change in control of the Company. These agreements are described under “Employment and Change in Control Agreements”, and detailed information is provided under “2022 Other Potential Post-Employment Payments.”

Retirement and Employee Welfare Benefits

We sponsor a retirement savings plan for employees of the Company and its affiliates (the “Retirement Savings Plan”) and a nonqualified deferred compensation plan for certain executive officers (the “Executive Deferred Compensation Plan”). We offer these plans, and make contributions to them, to provide employees with tax-advantaged savings vehicles and to encourage them to save money for their retirement. The Executive Deferred Compensation Plan is described under “Executive Compensation–Nonqualified Deferred Compensation.”

In addition to our retirement programs, we provide employees with welfare benefits, including hospitalization, major medical, disability and group life insurance plans and paid vacation. We also maintain a Section 125 cafeteria plan that allows our employees to set aside pre-tax dollars to pay for certain benefits. All of the full-time employees of the Company and the Bank, including the NEOs, are eligible to participate in the Retirement Savings Plan and our welfare plans, subject to the terms of those plans.

The Bank provides supplemental disability insurance to certain members of executive management, including the NEOs, in excess of the maximum benefit of $15,000 per month provided under the group plan for all employees. The supplemental insurance provides a benefit up to 70% of the executive’s monthly pre-disability income based on the executive’s base salary and annual incentive compensation not to exceed $17,500. Coverage can be converted and maintained by the individual participant after employment ends. The benefit may be reduced by income from other sources, and a partial benefit is paid if a disabled participant is able to work on a part-time basis. In 2022, the Company paid an aggregate of $4,930 for supplemental disability insurance for the NEOs.

The retirement and employee welfare benefits paid by the Company for the NEOs that are required to be disclosed in this proxy statement are included in the “Summary Compensation Table,” the “Components of All Other Compensation,” and the “Nonqualified Deferred Compensation Table,” and are described in the footnotes thereto.

Supplemental Executive Retirement Agreement

On December 10, 2021, the Company and the Bank entered into a Supplemental Executive Retirement Plan Agreement (the “SERP”) with Mr. Shaffer. The SERP is intended to provide retirement benefits to Mr. Shaffer. None of the other NEOs participate in the SERP. For additional information regarding the SERP, see the “Pension Benefits Table” and the narrative accompanying that table.

Executive Perquisites

We do not consider perquisites to be a significant element of our compensation program. However, we believe they are important and effective for attracting and retaining certain executive talent. We do not provide tax reimbursements, or “gross-ups,” on perquisites. For additional details regarding the executive perquisites, see the “Summary Compensation Table” and the “Components of All Other Compensation.”

PROXY STATEMENT 2023

Clawback Policy

We have adopted a Compensation Recoupment Policy to recover incentive compensation from any executive officer when:

| ● | the incentive compensation payment or award (or the vesting of such award) was based upon the achievement of financial results that were subsequently the subject of an accounting restatement, regardless of whether the executive engaged in misconduct or otherwise contributed to the requirement for the restatement; and

| ● | a lower payment or award would have been made to the executive officer based upon the restated financial results.

The policy is available on our website at www.SeacoastBanking.com and will be updated in accordance with new SEC and Nasdaq requirements.

Hedging and Pledging Policy

The Company has adopted a hedging and pledging policy. The policy prohibits our employees, including our executive officers and directors, from purchasing any financial instrument or entering into any transaction that is designed to hedge or offset any decrease in the market value of our stock, including, without limitation, exchange funds, prepaid variable forward contracts, equity swaps, puts, calls, collars, forwards or short sales.

In addition, directors and executive officers are required to obtain advance approval of any pledging of Company shares as collateral for loans, including holding Company shares in margin accounts. The policy also limits pledging to reasonable purposes (as defined in the policy) and limits the value of the securities pledged in connection with a loan or other indebtedness to $250,000.

Stock Ownership Guidelines

The Board has established stock ownership guidelines for its officers and directors, as described below:

Individual/Group | Stock Ownership Target | Holding Requirement
|  | Before Ownership Target Met | After Ownership Target Met
Chief Executive Officer | 5 times annual base salary | 75% of net shares until target number of shares is met | 50% of net shares held for one year after vesting/ exercise
Other Senior Executive Officers | 3 times annual base salary
Non-Employee Directors | 3 times annual retainer

Our executive compensation program is designed to allow a participant to earn targeted ownership over a reasonable period, usually within four years, provided individual and Company targets are achieved and provided the participant fully participates in the program. For purposes of these guidelines, “net shares” means shares of stock in excess of those sold or withheld to satisfy the minimum tax liability upon vesting or conversion. All of our NEOs and non-employee directors have met or are on track to meet their stock ownership target.

Strategies to Ensure that Incentive Compensation is Sensitive to Risk Considerations

The CGC and our Chief Risk Officer share the view that our incentive strategies strike the right balance between risk and reward, motivating and retaining our executives in ways that align with shareholder interests but do not motivate inappropriate or excessive risk taking. The evolution of our incentive strategies reflect our commitment to listen to our shareholders and continuously refine our programs to align with our governance and risk management efforts given the growth of Seacoast and changes within the industry and what is deemed as best practice.

Strategy | Compensation Design
Compensation is tied to equity and Company performance | ● Time-based RSAs vesting period is three years ● Performance period for PSU awards is three years, with an additional time-based vesting year following the performance period
Seacoast performance at levels that equal or exceed the industry | ● Annual incentive compensation that incorporates a quantitative component based on relative performance for ROTCE, EPS growth and pre-provision net revenue growth ● PSU metrics based on three-year average annual growth in EPS and average ROATE compared to peers, which the CGC views as key indicators of our performance
Governance Considerations | ● PSU performance period allows for direct and relevant pay and performance comparisons with industry competitors and alternative investments that share our risk profile ● PSU program includes two types of goals; PSUs will be earned for growth in average annual EPS, and PSUs will be earned for average annual ROATE, each compared to peer ratios ● PSU payouts are capped at target in the event that certain absolute Company performance levels in EPS and ROATE are not met ● No PSU payouts will be made in the event that Tier 1 Capital requirements are not maintained
Risk Considerations | ● PSUs for which performance goals are met will vest one year after the end of the performance period, subject to the grantee’s continued service ● In addition, we implemented a mandatory holding requirement on RSA and PSU awards so the grantee must hold at least 50% of the net shares received upon vesting for an additional 12 months ● Maintained service and risk-based vesting requirements on all new performance-contingent and performance-based equity awards ● Maintained “clawback” provisions for certain incentive-based compensation to ensure accountability

Risk Analysis of Incentive Compensation Plans

The CGC reviews the sensitivity of our performance and incentives to risk considerations for our executives throughout the year. It also periodically reviews our cash and equity incentive strategies for other key contributors. In 2022, the CGC with the assistance of our Chief Human Resources Officer completed a review of our incentive strategies for our incentive eligible non-executive employees. The CGC concluded that our incentive compensation programs are designed with the appropriate balance of risk and reward in relation to our overall business strategy, will not motivate people to take excessive or imprudent risks, and do not create risks that are reasonably likely to have a material adverse effect on the Company.

| (1) | Amount of salary actually received in any year may differ from the annual base salary amount due to the timing of changes in base salary, which typically occur in April or following a mid-year promotion. A portion of executive’s base salary included in this number may have been deferred into the Company’s Executive Deferred Compensation Plan (“EDCP”), the amounts of which are disclosed in the Nonqualified Deferred Compensation Table for the applicable year. Executive officers who are also directors do not receive any additional compensation for services provided as a director.

| (2) | Represents he aggregate grant date fair value as of the respective grant date for each award calculated in accordance with FASB ASC Topic 718. The assumptions made in valuing stock awards reported in this column are discussed in Note 1 to the Company’s audited financial statements included in its Annual Report on Form 10-K for the year ended December 31, 2022. Generally, the aggregate grant date fair value is the amount that the company expects to expense for accounting purposes and does not correspond to the actual value that the named executives will realize from the award. For additional information regarding such grants, see “Compensation Discussion and Analysis – Summary of Compensation Decisions in 2022 – Equity Awards.” See also “2022 Grants of Plan-Based Awards”.

In 2022, each of our NEOs received PSUs and RSAs. With respect to the PSU awards, the grant date fair value included in the table assumes that target performance is achieved. The grant date value for the PSUs, assuming the highest level of performance will be achieved, was:

The Company sponsors a SERP that is an unfunded nonqualified deferred compensation arrangement maintained primarily to provide supplemental retirement benefits for the CEO, who is a member of executive management and a highly compensated employee of the Company. Additional information regarding Mr. Shaffer’s SERP Agreement is provided in the “Employment and Change in Control Agreements” section.

On December 10, 2021, the Company and the Bank entered into a SERP Agreement with Mr. Shaffer. Pursuant to the SERP, upon Mr. Shaffer’s termination of service after attaining normal retirement age (age 67), he will receive an annual benefit in the amount of $350,000 payable in equal monthly installments and continuing for 20 years.

In the event of disability prior to normal retirement age, Mr. Shaffer will receive an amount equal to the SERP liability accrued by the under GAAP (the “Accrued Benefit”), calculated by applying a discount rate equal to the Moody’s “A” rated corporate bond rate (the “Discount Rate”), payable over 20 years following the normal retirement age. In the event of death or a change in control, Mr. Shaffer or his beneficiary will receive a lump sum benefit equal to the present value of the normal retirement benefit, discounted back from the normal retirement age to the date of death or the date of the change in control.

If Mr. Shaffer is terminated without cause prior to the normal retirement date, he will receive the Accrued Benefit, determined as of the end of the year preceding the date of separation, and interest will be credited on the Accrued Benefit until the final payment is made at a rate equal to the Discount Rate in effect at the time of the separation. This early involuntary termination benefit would be paid over 20 years following the normal retirement age. If Mr. Shaffer’s early termination is voluntary, the Accrued Benefit will not be credited with interest and will be reduced by a vesting percentage if such voluntary termination occurs prior to December 31, 2030. The vesting percentage is 10% for voluntary separations per year through December 31, 2030. This early voluntary termination benefit would be paid over 20 years following the normal retirement age.

In the event that Mr. Shaffer breaches any non-competition, non-hire, non-solicitation, non-disparagement or confidentiality obligations he has to the company or any of its affiliates pursuant to his Employment Agreement, he will immediately forfeit any non-distributed SERP benefits. In addition, Mr. Shaffer will not be entitled to any SERP benefits if his service is terminated for cause (as defined in the SERP) or if an insurance company which issued a life insurance policy owned by the Company or the Bank and covering Mr. Shaffer, denies coverage for material misstatements of fact made by him on an application for life insurance.

Executive Deferred Compensation Plan

The Bank’s Executive Deferred Compensation Plan (“EDCP”) is designed to permit a select group of management and highly compensated employees, including the NEOs, to elect to defer a portion of their compensation until their separation from service with the Company, and to receive matching and other Company contributions that are precluded under the Company’s Retirement Savings Plan as a result of limitations imposed under ERISA.

The EDCP was also amended and restated in 2022 to reflect additional participant options to the plan as follows:

| ● | contributions and investment gains or losses that were earned and vested on or before December 31, 2004, and any subsequent investment gains or losses thereon (the “Grandfathered Benefits”); and

| ● | contributions and earnings that were earned and vested after December 31, 2004 (the “Non-Grandfathered Benefits”).

The Executive Deferred Compensation Plan was also amended and restated in 2022 to reflect additional participant options to the plan as follows:

| ● | post-employment payment options of distribution timing and form for payment, including allowing for payments via lump sum or in installments after the executive’s death, at a specified date (for future deferrals), and/or upon a Change in Control; and

| ● | subsequent deferral option

A participant’s elective deferrals to the EDCP are immediately vested. The Company contributions to the EDCP vest at the rate of 25 percent for each year of service the participant has accrued under the Retirement Savings Plan, with full vesting after four years of service. If a participant would become immediately vested in his Company contributions under the Retirement Savings Plan for any reason (such as death, disability, or retirement on or after age 55), then he would also become immediately vested in his account balance held in the EDCP.

Each participant directs how his or her account in the EDCP is presumably invested among the available investment vehicle options. The plan’s investment options are reviewed and selected annually by a committee appointed by the Board of Directors of the Company to administer the plan. The plan committee may appoint other persons or entities to assist it in its functions. No earnings or dividends paid under the EDCP are above-market or preferential.

All amounts paid under the plan are paid in cash from the general assets of the Company, either directly by the Company or via a “rabbi trust” the Company has established in connection with the plan. Nothing contained in the plan creates a trust or fiduciary relationship of any kind between the Company and a participant, beneficiary or other person having a claim to payments under the plan. A participant or beneficiary does not have an interest in his plan account that is greater than that of an unsecured creditor.

Upon a participant’s separation from service with the Company, he or she will receive the balance of his or her account in cash in one of the following three forms specified by the participant at the time of initial deferral election, or a subsequent permitted amendment:

| ● | a lump sum;

| ● | monthly installments over a period not to exceed five years; or

| ● | a combination of an initial lump sum of a specified dollar amount and the remainder in monthly installments over a period not to exceed five (5) years.

A participant may change his or her existing distribution election relating to Non-Grandfathered Benefits only in very limited circumstances. Upon death of the participant, any balance in his or her account will be paid in a lump sum to his designated beneficiary or to his estate.

2022 Nonqualified Deferred Compensation

The following table discloses, for each of the NEOs, contributions, earnings and balances during 2022 under the EDCP, described above.

PROXY STATEMENT 2023

CEO Pay Ratio

We are providing the following information to comply with Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(u) of Regulation S-K. For our last completed fiscal quarter at December 31, 2022, the median annual total compensation of our employees (other than Mr. Shaffer, our CEO in 2022) was $68,581 and the annual total compensation for Mr. Shaffer, as reported in the Summary Compensation Table was $2,824,576. Based on this information, for 2022, the ratio of compensation for our Chief Executive Officer to the median employee was 46:1. This ratio is specific to our Company and may not be comparable to any ratio disclosed by another company.

Seacoast identified the median associate for 2020 based on our workforce as of December 31, 2020, and utilized the same associate for 2021 and 2022 as there has been no change in our employee population or compensation arrangements that we believe would significantly impact our pay ratio disclosure. Using our human resource information system (“HRIS”) we were able to determine any compensation earned by associates including regular pay, incentive, bonus, business continuity, and any other prerequisites. No assumptions, adjustments, or estimates, including any cost of living adjustments were made in identifying the median employee. Next we calculated the median employee’s annual total compensation for 2022 in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K for the Summary Compensation Table, consistent with the calculations we provide all of our Named Executive Officers. No adjustments were made to the annual total compensation of our Chief Executive Officer, as reported in the Summary Compensation Table, to calculate the reported ratio of the annual total compensation of our Chief Executive Officer to the median of the annual total compensation of all employees.

Equity Compensation Plan Information

The following table sets forth information about the Company’s common stock that may be issued under all of our existing compensation plans as of December 31, 2022.

PROPOSAL 1

ELECTION OF DIRECTORS

General

Our non-employee directors are appointed to act on behalf of our shareholders by overseeing critical aspects of our business strategy, operations, risk management and governance efforts. Our belief is that superior talent in the boardroom should generate exceptional levels of customer service, financial performance and, ultimately, superior shareholder returns compared to alternative investments. To this end, the Board is committed to identifying the best available talent to make meaningful contributions to our business and fully execute its duties and responsibilities on behalf of shareholders. The profile of our Board continues to evolve in response to the needs of a dynamic and growing organization. Our Board of Directors plays a meaningful role in helping Seacoast develop, test and implement our business, risk management, talent and reward strategies. The Board’s activities are focused on representing our shareholders in ways that position Seacoast to create significant value for customers, employees and our shareholders within a risk appropriate framework. For additional detail regarding skills and qualifications of our directors, see “Skills and Qualification Mix.”

In accordance with our bylaws and as set forth in the proposed amendment to our Amended and Restated Articles of Incorporation, in no event will the Board have fewer than 3 directors or more than 14 directors. As of the date of this proxy statement, Seacoast’s Board of Directors consists of 11 members divided into three classes, serving staggered three-year terms as provided in our Articles of Incorporation. At this time, Seacoast’s Compensation and Governance Committee (“CGC”) and Board of Directors believe that 11 directors is adequate to provide a diversity of background, experience and expertise, and that there are sufficient independent directors to staff the independent committees of the Board and provide independent oversight.

The Annual Meeting is being held to, among other things, elect three Class III directors of Seacoast, each of whom has been nominated by the CGC of the Board of Directors. Each of the nominees is presently a director of Seacoast. All of the nominees will also serve as members of the Board of Directors of Seacoast National Bank (the “Bank”). The members of the Boards of Directors of the Bank and the Company are the same except for Dale M. Hudson, who is currently a director of the Bank only. If elected, each Class III director nominee will serve a three year term expiring at the 2026 Annual Meeting and until their successors have been elected and qualified.

Currently, the Board of Directors is classified as follows:

Class | Term | Names of Directors
Class I | Term Expires at the 2024 Annual Meeting | Jacqueline L. Bradley H. Gilbert Culbreth, Jr. Christopher E. Fogal Charles M. Shaffer
Class II | Term Expires at the 2025 Annual Meeting | Dennis J. Arczynski Maryann Goebel Robert J. Lipstein Thomas E. Rossin
Class III | Term Expires at the 2023 Annual Meeting | Julie H. Daum Dennis S. Hudson, III Alvaro J. Monserrat

Manner for Voting Proxies

All shares represented by valid proxies, and not revoked before they are exercised, will be voted in the manner specified therein. If a valid proxy is submitted but no vote is specified, the proxy will be voted FOR the election of each of the three nominees for election as directors. Please note that banks and brokers that do not receive voting instructions from their clients are not able to vote their client’s shares in the election of directors. Although all nominees are expected to serve if elected, if any nominee is unable to serve, then the persons designated as proxies will vote for the remaining nominees and for such replacements, if any, as may be nominated by the CGC. Proxies cannot be voted for a greater number of persons than the number of nominees specified herein (three persons). Cumulative voting is not permitted.

The affirmative vote of the holders of shares of common stock representing a plurality of the votes cast at the Annual Meeting at which a quorum is present is required for the election of the directors listed below, which means that the director nominees who receive the highest votes “for” their election are elected. However, to provide shareholders with a meaningful role in uncontested director elections, which is the case for the election of the director nominees listed below, our Corporate Governance Guidelines provide that if any director nominee receives a greater number of votes “withheld” for his or her election than votes “for” such election, then the director will promptly tender his or her resignation to the Board following certification of the shareholder vote. The CGC would then review and make a recommendation to the Board of Directors as to whether the Board should accept the resignation, and the Board would ultimately decide whether to accept or reject the resignation. If any resignation is accepted by the Board, such resignation will be effective upon acceptance. The Company will disclose its decision-making process regarding any resignation in a Form 8-K filed with the SEC. In contested elections, the required vote would be a plurality of votes cast and the resignation policy would not apply.

Further details of this policy and the corresponding procedures are set forth in our Corporate Governance Guidelines, available on our website at www.SeacoastBanking.com.

Director Compensation

Decisions regarding our non-employee director compensation program are approved by our full board of directors based on recommendations from the CGC. In making its recommendations, the CGC considers the director compensation practices of peer companies and whether such recommendations align with the interests of our shareholders with respect to total compensation and each element thereof based on a peer group study conducted by the Company’s compensation consultant. For more information about the peer group, see “Compensation Peer Group.” Our compensation program for non-employee directors is designed to:

| ● | appropriately compensate directors for the work required at a company of Seacoast’s size, growth, and dynamic and evolving business model;

| ● | align directors’ interests with the long-term interests of Seacoast’s shareholders; and

| ● | make meaningful adjustments every few years, rather than small annual adjustments.

Non-Employee Director Compensation Structure

Annual Retainer paid to all Non-employee Directors of the Company in 2022:
Cash (1) | $45,000
Stock Award (2) | $62,500
Annual Committee Chair Retainer for all Committees | $25,000

| (1) | A number of directors have elected to receive all or a portion of their cash retainer in stock or stock options as described below.

| (2) | Granted under the Amended 2021 Incentive Plan following election or re-election at each annual meeting of shareholders.

All cash retainers are paid in quarterly installments. To further align directors’ interests with long-term shareholder interests, directors may elect to receive: 1) all or a portion of their annual cash retainer in vested Company common stock, and 2) up to a maximum of 30% of their annual cash retainer in the form of vested non-qualified options to purchase shares of Company common stock. Retainers are pro-rated for directors who join or leave the Board or have a change in Board role during a quarterly period. In 2022, the annual cash retainer increased by $7,500.

Non-employee directors are also reimbursed for their travel, lodging and related expenses incurred in connection with attending Board, committee and shareholders’ meetings and other designated Company events. Executive officers who are also directors do not receive any compensation for services provided as a director.

Lead Independent Director Compensation

The Board appointed Christopher E. Fogal as Lead Independent Director in December 2018. In 2022, Mr. Fogal received an additional annual cash retainer of $35,000 for his service as Lead Independent Director.

Director Stock Ownership Policy

To align the interests of our directors and shareholders, our Board of Directors believes that directors should hold a significant financial stake in Seacoast. Consequently, our Corporate Governance Guidelines require that directors own Seacoast stock equal in value to a minimum of three times their base annual retainer within four years of joining the Board. Each director must retain 75% of their shares until reaching the minimum share ownership requirement, and after the ownership target is met, must retain at least 50% of the shares for one year. All of our directors own more than the minimum stock requirement.

The table below sets forth the total compensation paid to Board members who are not employees of the Company or the Bank for fiscal year 2022.

Directors’ Deferred Compensation Plan

The Company has a Directors’ Deferred Compensation Plan (“DDCP”) to allow each non-employee director of the Company and the Bank to defer receipt of his or her director compensation, both cash and equity, until his or her separation from service with the Company. Each participant account is separated into sub-accounts for cash deferrals (“Cash Deferral Account”) and equity deferrals (“Equity Deferral Account”). Each participant directs how his or her Cash Deferral Account in the DDCP is invested among the available investment vehicle options, including a Company stock fund (“Stock Account”). The plan’s investment options are reviewed and selected annually by a committee appointed by the Board of Directors of the Company to administer the plan. No earnings or dividends paid under the DDCP are above-market or preferential.

All amounts paid under the DDCP are paid in cash (other than as described with respect to the Stock Account or Equity Deferral Account) from the general assets of the Company, either directly by the Company or via a “rabbi trust” the Company has established in connection with the plan. Nothing contained in the plan creates a trust or fiduciary relationship of any kind between the Company and a participant, beneficiary or other person having a claim to payments under the plan. A participant or beneficiary does not have an interest in his or her plan account that is greater than that of an unsecured creditor.

The DDCP was amended and restated in 2022 to reflect additional participant options to the plan as follows:

| ● | post-employment payment options of distribution timing and form for payment, including allowing for payments via lump sum or in installments after the executive’s death, at a specified date (for future deferrals), and/or upon a Change in Control; and

| ● | subsequent deferral option

| ● | flexibility to transfer outstanding non-deferred equity awards to family members and trusts within the applicable tax rules under 409A

Upon a participant’s separation from service, the participant will receive the balance of his or her Stock Account and/or Equity Deferral Account in shares of Company common stock and the balance of his or her other plan accounts in cash in one of the following three forms specified by the participant at the time of initial deferral election: i) a lump sum; ii) monthly installments over a period not to exceed eleven years; or iii) a combination of an initial lump sum of a specified dollar amount and the remainder in monthly, quarterly or annual installments over a period not to exceed eleven years. Upon death of a participant, any balance in his or her account shall be paid in accordance with the participant election to his or her designated beneficiary or to his or her estate.

PROPOSAL 2

APPROVAL OF AMENDEMENT TO THE AMENDED

AND RESTATED ARTICLES OF INCORPORATION OF

SEACOAST BANKING CORPORATION OF FLORIDA

On January 25, 2023, our Board of Directors adopted, subject to shareholder approval at the Annual Meeting, an amendment to our Amended and Restated Articles of Incorporation to revise an error in certain language with respect to the size of the Board of Directors.

The proposed amendment to Seacoast’s Amended and Restated Articles of Incorporation is attached to this proxy statement as Appendix B. No other changes to the Company’s Articles of Incorporation are being proposed.

Reason for Amendment

Our Board of Directors is proposing the adoption of an amendment to the Company's Amended and Restated Articles of Incorporation to eliminate an internal inconsistency in the Company's Articles regarding the minimum number of directors that the Company may have at any given time. The Company's existing Articles provide inconsistently that the minimum number of directors is 3 but also that in no event shall the Board of Directors have fewer than 11 directors. The amendment will eliminate the provisions for an 11 board member minimum and instead result in a Board that must have a minimum of 3 members and a maximum of 14 members. This amendment also aligns the Company's Articles with the Company's existing Bylaws which also sets forth a 3 member minimum and 14 member maximum Board.

The Company reviewed historical corporate records and determined inclusion of the 11-director minimum was a scrivener's error.

If Proposal 2 is approved, the amendment will be effective upon the filing of the Articles of Amendment to the Amended and Restated Articles of Incorporation with the Department of State of the State of Florida promptly after the Annual Meeting.

The Board of Directors unanimously recommends a vote “FOR” Proposal 2.

PROXY STATEMENT 2023

PROPOSAL 3

AMEND THE COMPANY’S AMENDED 2021 INCENTIVE PLAN TO

INCREASE AUTHORIZED SHARES

We are asking our shareholders to approve an amendment to the Seacoast Banking Corporation of Florida Amended 2021 Incentive Plan (the “2021 Plan”). Our 2021 Plan is the only plan under which equity-based compensation may currently be awarded to our executive officers, employees, directors, consultants and advisors. As of the Record Date, there were 283,152 shares of our common stock remaining available for the grant of equity awards under the 2021 Plan. In order to enable us to continue to offer meaningful equity-based incentives, as well as cash-based incentives, to our employees, officers, directors, consultants, and advisors, our board of directors believes that it is both necessary and appropriate to increase the number of shares of our common stock available for these purposes. As a result, on March 30, 2023, the Board of Directors adopted, subject to shareholder approval at the Annual Meeting, an amendment to add 2,000,000 shares to the 2021 Plan. The share increase is the only change to the 2021 Plan, a summary of which is provided below.

If the amendment to the 2021 Plan is approved by our shareholders at the Annual Meeting, it will become effective on the date of the Annual Meeting. If the amendment is not approved by our shareholders, then the 2021 Plan will remain in effect as it presently exists.

Background for the Current Request to Approve an Increase in the Share Reserve under the 2021 Plan

In setting the number of proposed shares issuable under our 2021 Plan, our Compensation and Governance Committee and our Board of Directors considered a number of factors, including the following (each of which are discussed further below):

| ● | Key data relating to outstanding equity awards and shares available for grant;

| ● | Significant historical award information; and

| ● | Future share needs.

Information Regarding our Authorized Shares and Stock Price

Our amended and restated articles of incorporation authorize the issuance of 120 million shares of common stock. As of our Record Date, there were ( • ) shares of common stock issued and outstanding and the closing price of a share of our common stock as of that date was $24.44.

Significant Historical Award Information

Common measures of a stock plan’s cost include burn rate, dilution and overhang. The burn rate refers to how fast a company uses the supply of shares authorized for issuance under its stock plan. Dilution measures the degree to which our shareholders’ ownership has been diluted by stock-based compensation awarded under our various equity plans and also includes shares that may be awarded under our various equity plans in the future, which is commonly referred to as overhang.

We closely monitor our share usage and believe we have been judicious in our use of shares previously authorized by our shareholders under the 2021 Plan. The following table and related footnotes show our key equity metrics over the last three years.

The following table includes our value-adjusted burn rate and other key metrics.

Burn Rate (1) | Key Metrics (At Target)
Year | Number of Options (#) | Option Value ($) | Full Value Awards (#) | 200-Day Average Stock Price ($) | Weighted Common Shares Outstanding (CSO) (#) | Value- Adjusted Burn Rate (%) | Overhang (2) (%) | Dilution (3) (%)
2020 | -- | -- | 678,631 | 20.59 | 53,930,289 | 1.26 | 4.50 | 3.53
2021 | 356,497 | 15.73 | 309,284 | 35.05 | 57,088,000 | 0.82 | 6.88 | 2.55
2022 | 516,563 | 18.53 | 536,458 | 33.38 | 64,264,229 | 1.28 | 4.38 | 2.32
Average Total | 291,020 | 508,124 | 799,144 | 29.67 | 58,427,506 | 1.06 | 5.25 | 2.80

| (1) | Value-adjusted burn rate is calculated under Institutional Stockholder Services, or ISS, methodology. Our value-adjusted burn rate is 1.06% compared to the banking industry benchmark for Russell 3000 companies of 1.05%, slightly above benchmark. As part of Bank aquisition activity in 2021 and 2022, Seacoast issued substitute stock options representing 873,060 shares. These were the only stock options granted in the three-year period; with the exception of 1,505 shares granted as part of director compensation. Refer to table titled

| (2) | Overhang is calculated by dividing (a) the sum of (x) the number of shares subject to equity awards outstanding at the end of the year and (y) the number of shares available for future grants, by (b) the number of shares outstanding at the end of the year.

| (3) | Dilution is calculated by dividing the number of shares subject to equity awards outstanding at the end of the fiscal year by the number of shares outstanding at the end of the fiscal year.

Number of Shares Requested

Several factors were evaluated in determining to request an increase of 2,000,000 shares for the 2021 Plan:

| ● | The original 2021 Plan authorized 1,750,000 shares. The additional 2,000,000 shares requested under this proposal, together with the remaining shares under the 2021 Plan, represent the shares the Company anticipates needing for the next three (3) years under normal circumstances and based on historical share usage.

| ● | Although we must manage our share reserve under the possibility that awards will be earned at the maximum level, this will only occur if we achieve the maximum performance under each metric in each award, which is not expected to be the case. Our actual share usage will also vary from our estimate based upon changes in market grant values, changes in the number of recipients, changes in our stock price, changes in the structure of our long-term incentive program, changes in our dividend rate and forfeitures of outstanding awards. We believe that the proposed share reserve reflects an appropriate balance between our desire to allow maximum flexibility in a competitive labor market and shareholder interests of limiting dilution.

| ● | As of the Record Date, the plan share reserve represented less than 0.1% of our common shares outstanding.

| ● | As of the Record Date, the total overhang resulting from the share request, including our outstanding awards under the 2021 Plan represents approximately 2.32% of our fully-diluted common shares outstanding.

Aside from the increase in shares available under the 2021 Plan, the current proposal does not amend or change any provisions of the 2021 Plan, which was approved by shareholders at the 2021 annual meeting. However, to enable you to evaluate the proposed share increase, the following is a description of the material terms of the 2021 Plan.

Summary of the 2021 Plan

Important Provisions

The 2021 Plan contains a number of provisions that we believe are consistent with the interests of shareholders and sound corporate governance practices, including:

| ● | No liberal share counting. The plan prohibits the reuse of shares withheld or delivered to satisfy the exercise price of an option or Stock Appreciation Right (“SAR”) or to satisfy tax withholding requirements.

55

PROXY STATEMENT 2023

| ● | No repricing of stock options or SARs. The exercise price of a stock option or SAR may not be reduced, directly, or indirectly, without the prior approval of shareholders, including the exchange for cash or another award or by a cash repurchase of “under water” awards.

| ● | No discounted stock options or SARs. All stock options and SARs must have an exercise price or base price equal to or greater than the fair market value of the underlying common stock on the date of grant.

| ● | No dividends on unearned awards. The plan prohibits the current payment of dividends or dividend equivalent rights on unearned awards.

| ● | Compensation recoupment policy. Awards under the plan will be subject to any compensation recoupment policy that the Company may adopt from time to time.

| ● | No single trigger change of control vesting. If awards granted under the 2021 Plan are assumed by the successor entity in connection with a change of control of the Company, such awards will not automatically vest and pay out upon the change of control.

Purpose

The purpose of the 2021 Plan is to promote the success, and enhance the value of the Company is success by linking the personal interests of its employees, officers, directors, consultants and advisors to those of the Company’s shareholders, and by providing participants with an incentive for outstanding performance. The Plan is further intended to provide flexibility to the Company in its ability to motivate, attract, and retain the services of employees, officers, directors, consultants and advisors upon whose judgment, interest, and special effort the successful conduct of the Company’s operation is largely dependent. As of the record date, approximately 1,608 employees (including officers), 11 non-employee directors (including Bank directors), 0 consultants and 0 advisors would be eligible to receive awards under the 2021 Plan.

Permissible Awards

The 2021 Plan authorizes the grant of awards in any of the following forms:

| ● | Options to purchase shares of common stock, which may be nonstatutory stock options or incentive stock options under the U.S. Internal Revenue Code (the “Code”). The exercise price of an option granted under the 2021 Plan may not be less than the fair market value of the Company’s common stock on the date of grant. Stock options granted under the 2021 Plan have a maximum term of ten years.

| ● | Stock appreciation rights, or SARs, which give the holder the right to receive the excess, if any, of the fair market value of one share of common stock on the date of exercise, over the base price of the stock appreciation right. The base price of a SAR may not be less than the fair market value of the Company’s common stock on the date of grant. SARs granted under the 2021 Plan have a maximum term of ten years.

| ● | Restricted stock, which is subject to restrictions on transferability and subject to forfeiture on terms set by the Committee.

| ● | Restricted stock units, which represent the right to receive shares of common stock (or an equivalent value in cash or other property) in the future, based upon the attainment of stated vesting or performance goals set by the Committee.

| ● | Deferred stock units, which represent the right to receive shares of common stock (or an equivalent value in cash or other property) in the future, generally without any vesting or performance restrictions.

| ● | Cash-based awards.

| ● | Performance awards.

| ● | Other stock-based awards in the discretion of the Committee, including unrestricted stock grants.

All awards will be evidenced by a written award certificate between the Company and the participant, which will include such provisions as may be specified by the Committee. Dividend equivalent rights, which entitle the participant to payments in cash or property calculated by reference to the amount of dividends paid on the shares of stock underlying an award, may be granted with respect to awards other than options or SARs.

Awards to Non-Employee Directors

The maximum aggregate number of shares subject to awards that may be granted under the 2021 Plan to any non-employee director in any calendar year is limited to a number that, combined with any cash meeting fees or cash retainers, does not exceed $750,000 in total value, including in the case of a non-employee Chairman of the Board or Lead Director.

Shares Available for Awards

In 2021, shareholders approved an aggregate of 1,750,000 shares under the 2021 Plan, plus a number of shares (not to exceed 661,128) underlying awards outstanding under our prior plan as of the effective date of the 2021 Plan that terminate or expire unexercised or are cancelled, forfeited or lapse for any reason. The current proposal will add 2,000,000 shares, for a total of 3,750,000 shares available under the 2021 Plan, plus such shares subject to awards under our prior plan that are terminated, expired, cancelled, forfeited or lapsed. This amount is reduced by the number of shares that have already been granted under the 2021 Plan, as discussed above. No further awards are being granted under any prior plans, and any prior plans sponsored by the Company shall remain in effect only so long as awards granted thereunder shall remain outstanding. The maximum number of shares that may be issued upon exercise of incentive stock options granted under the 2021 Plan is 3,750,000.

56

SEACOAST BANKING CORPORATION OF FLORIDA

Share Counting

Shares subject to awards that terminate or expire unexercised, or are cancelled, forfeited or lapse for any reason, and shares underlying awards that are ultimately settled in cash, will again be available for future grants of awards under the 2021 Plan. Similarly, to the extent that the full number of shares subject to a performance award is not issued by reason of failure to achieve maximum performance goals, the unearned shares originally subject to the award will be added back to the 2021 Plan share reserve and again be available for issuance pursuant to awards granted under the 2021 Plan. However, the following shares may not again be made available for issuance as awards under the 2021 Plan: (i) shares not issued or delivered as a result of the net settlement of an outstanding option or SAR, (ii) shares used to pay the exercise price or withholding taxes related to an outstanding option or SAR, or (iii) shares repurchased on the open market with the proceeds of the exercise price of an option. The maximum number of shares that may be issued upon exercise of incentive stock options granted under the 2021 Plan is 3,750,000.

Key Data Relating to Outstanding Awards

The following table provides information regarding outstanding equity awards and shares available for future awards under the 2021 Plan as of our Record Date (and without giving effect to approval of the amendment to the 2021 Plan under this proposal).

Total shares underlying outstanding stock options | 1,190,846
Weighted-average exercise price of outstanding stock options | $18.33
Weighted-average remaining contractual life of outstanding stock options | 3.4 years
Total shares underlying full value awards outstanding | 269,979
Total shares currently available for grant | 1,270,887

Administration

The 2021 Plan will be administered by the Compensation and Governance Committee, or such other committee as may be determined by the Board (the “Committee”). The Committee will have the authority to grant awards; designate participants; determine the type or types of awards to be granted to each participant and the number, terms and conditions thereof; establish, adopt or revise any rules and regulations as it may deem advisable to administer the 2021 Plan; prescribe forms of award certificates, and make any rules, interpretations, and any and all other decisions and determinations that may be required under the 2021 Plan. The Board may at any time administer the 2021 Plan. If it does so, it will have all the powers of the Committee under the 2021 Plan.

In addition, the Board or the Committee may expressly delegate to a special committee some or all of the Committee’s authority, within specified parameters, to grant awards to eligible participants who, at the time of grant, are not executive officers.

Limitations on Transfer; Beneficiaries

No award will be assignable or transferable by a participant other than by will or the laws of descent and distribution; provided, however, that the Committee may permit other transfers (other than transfers for value) where the Committee concludes that such transferability does not result in accelerated taxation, does not cause any option intended to be an incentive stock option to fail to qualify as such, and is otherwise appropriate and desirable, taking into account any factors deemed relevant, including without limitation, any state or federal tax or securities laws or regulations applicable to transferable awards. A participant may, in the manner determined by the Committee, designate a beneficiary to exercise the rights of the participant and to receive any distribution with respect to any award upon the participant’s death.

Acceleration upon Certain Events

Treatment of Awards upon a Participant’s Death or Disability

Unless otherwise provided in an award certificate or any special plan document governing an award, upon the termination of a participant’s service due to death or disability:

| ● | each of that participant’s outstanding options and SARs, or portions of such outstanding Options and SARs, as applicable, that are solely subject to time-based vesting requirements shall become vested and fully exercisable as of the date of termination, and shall thereafter remain exercisable for a period of one (1) year or until the earlier expiration of the original term of the Option or SAR;

| ● | each of that Participant’s other outstanding Awards, or the portions of such other outstanding Awards, as applicable, that are solely subject to time-based vesting restrictions shall become vested, and such restrictions shall lapse of the date of termination; and

| ● | the payout opportunities attainable under each of that participant’s outstanding Options, SARs, and other Awards, or the portions of such outstanding Options, SAR and other Awards, as applicable, that are solely subject to performance-vesting requirements or restrictions shall be deemed to have been earned as of the date of termination as follows:

57

PROXY STATEMENT 2023

| ○ | if the date of termination occurs during the first half of the applicable performance period, all relevant performance goals will be deemed to have been achieved at the “target” level.

| ○ | if the date of termination occurs during the second half of the applicable performance period, the awards will be deemed to have been achieved at the greater of the “target” level or the level of achievement as measured at the end of the quarter immediately preceding the date of termination.

Treatment of Awards upon a Participant’s Retirement

The 2021 Plan does not provide special treatment for a participant’s retirement. Any such treatment may be addressed in an individual award certificate, or left to the Committee’s discretion.

Treatment of Awards upon a Change in Control

Unless otherwise provided in an award certificate or any special plan document governing an award:

| (A) | upon the occurrence of a change in control of the Company in which awards are not assumed by the surviving entity or otherwise equitably converted or substituted in connection with the change in control in a manner approved by the Committee or the Board:

| ● | all outstanding options and SARs will become fully vested and exercisable;

| ● | all time-based vesting restrictions on outstanding awards will lapse as of the date of the change in control; and

| ● | the payout opportunities attainable under all outstanding performance-based awards will vest based on target (if the change in control occurs during the first half of the performance period) or actual performance measured (if greater) as of the date of the change in control (if the change in control occurs during the second half of the performance period), and

| (B) | with respect to awards assumed by the surviving entity or otherwise equitably converted or substituted in connection with a change in control, if within two years after the effective date of the change in control, a participant’s employment is terminated without Cause or the participant resigns for Good Reason (as such terms are defined), then:

| ● | all of that participant’s outstanding options and SARs will become fully vested and exercisable;

| ● | all time-based vesting restrictions on that participant’s outstanding awards will lapse as of the date of termination; and

| ● | the payout opportunities attainable under all outstanding performance-based awards will vest based on target (if the change in control occurs during the first half of the performance period) or actual performance measured as of the end of the calendar quarter immediately preceding the change in control (if the change in control occurs during the second half of the performance period). In both cases, the awards will payout on a pro rata basis, based on the time elapsed prior to the change in control.

Acceleration for Other Reasons

The Committee may, in its sole discretion determine that, upon a Participant’s termination of service or a change in control, all or a portion of such participant’s awards shall become fully or partially exercisable, that some or all restrictions shall lapse, and that any performance criteria shall be deemed fully or partially satisfied. The Committee may provide different treatment among participants and among awards in exercising this discretion.

Adjustments

In the event of a nonreciprocal transaction between the Company and its shareholders that causes the per share value of the common stock to change (including, without limitation, any stock dividend, stock split, reverse stock split, spin-off, rights offering, or large nonrecurring cash dividend), the share authorization limits under the 2021 Plan will be adjusted proportionately, and the Committee must make such adjustments to the 2021 Plan and awards as it deems necessary, in its sole discretion, to prevent dilution or enlargement of rights immediately resulting from such transaction.

Termination and Amendment

If the increase in shares is approved by shareholders at the Annual Meeting, the 2021 Plan will terminate on the tenth anniversary of the date of the Annual Meeting. Otherwise, the 2021 Plan will terminate on the tenth anniversary of the date of the 2021 Annual Meeting. In either case, the 2021 Plan may be terminated earlier by the Board or the Committee. The Board or the Committee may, at any time and from time to time, terminate or amend the 2021 Plan, but if an amendment to the 2021 Plan would constitute a material amendment requiring shareholder approval under applicable listing requirements, laws, policies or regulations, then such amendment will be subject to shareholder approval. No termination or amendment of the 2021 Plan may adversely affect any award previously granted under the 2021 Plan without the written consent of the participant. Without the prior approval of the Company’s shareholders, the 2021 Plan may not be amended to directly or indirectly reprice, replace or repurchase “underwater” options or SARs.

The Committee may amend or terminate outstanding awards. However, such amendments may require the consent of the participant and, unless approved by the shareholders or otherwise permitted by the anti-dilution provisions of the 2021 Plan, (i) the exercise price or base price of an option or SAR may not be reduced, directly or indirectly, (ii) an option or SAR may not be cancelled in exchange for options, SARS or other awards with an exercise price or base price that is less than the exercise price or base price of the original option or SAR, or otherwise, and (iii) the Company may not repurchase an option or SAR for value (in cash or otherwise) from a participant if the current fair market value of the shares of common stock underlying the option or SAR is lower than the exercise price or base price per share of the option or SAR.

Prohibition on Repricing

Without the prior consent of the Company’s shareholders, outstanding stock options and SARs cannot be repriced, directly or indirectly, nor may stock options or SARs be cancelled in exchanged for stock options or SARs with an exercise or base price that is less than the exercise price or base price of the original stock options or SARs. In addition, the Company may not, without the prior approval of shareholders, repurchase an option or stock appreciation right for value from a participant, or cancel an option or stock appreciation right in exchange for other awards, if the current market value of the underlying stock is lower than the exercise price per share of the option or stock appreciation right.

Certain Federal Tax Effects

The following discussion is limited to a summary of the U.S. federal income tax provisions relating to the grant, exercise, vesting of awards and the subsequent sale of common stock acquired under the 2021 Plan. The tax consequences of awards may vary depending upon the particular circumstances, and it should be noted that the income tax laws, regulations and interpretations thereof change frequently. Participants should rely upon their own tax advisors for advice concerning the specific tax consequences applicable to them, including the applicability and effect of state, local, and foreign tax laws.

Nonstatutory Stock Options

There will be no federal income tax consequences to the optionee or to the Company upon the grant of a nonstatutory stock option under the 2021 Plan. When the optionee exercises a nonstatutory option, however, he or she will recognize ordinary income in an amount equal to the excess of the fair market value of the common stock received upon exercise of the option at the time of exercise over the exercise price, and the Company will be allowed a corresponding deduction. Any gain that the optionee realizes when he or she later sells or disposes of the option shares will be short-term or long-term capital gain, depending on how long the shares were held.

Incentive Stock Options

There typically will be no federal income tax consequences to the optionee or to the Company upon the grant or exercise of an incentive stock option. If the optionee holds the option shares for the required holding period of at least two years after the date the option was granted or one year after exercise, the difference between the exercise price and the amount realized upon sale or disposition of the option shares will be long-term capital gain or loss, and the Company will not be entitled to a federal income tax deduction. If the optionee disposes of the option shares in a sale, exchange, or other disqualifying disposition before the required holding period ends, he or she will recognize taxable ordinary income in an amount equal to the excess of the fair market value of the option shares at the time of exercise (or, if less, the amount realized on the disposition of the shares) over the exercise price, and the Company will be allowed a federal income tax deduction equal to such amount. While the exercise of an incentive stock option does not result in current taxable income, the excess of the fair market value of the option shares at the time of exercise over the exercise price will be an item of adjustment for purposes of determining the optionee’s alternative minimum taxable income.

Stock Appreciation Rights

A participant receiving a stock appreciation right will not recognize income, and the Company will not be allowed a tax deduction, at the time the award is granted. When the participant exercises the stock appreciation right, the amount of cash and the fair market value of any shares of common stock received will be ordinary income to the participant and the Company will be allowed a corresponding federal income tax deduction at that time.

59

PROXY STATEMENT 2023

Restricted Stock

Unless a participant makes an election to accelerate recognition of income to the date of grant as described below, the participant will not recognize income, and the Company will not be allowed a tax deduction, at the time a restricted stock award is granted, provided that the award is subject to restrictions on transfer and is subject to a substantial risk of forfeiture. When the restrictions lapse, the participant will recognize ordinary income equal to the fair market value of the common stock as of that date (less any amount he or she paid for the stock), and the Company will be allowed a corresponding federal income tax deduction at that time, subject to any applicable limitations under Code Section 162(m). If the participant files an election under Code Section 83(b) within 30 days after the date of grant of the restricted stock, he or she will recognize ordinary income as of the date of grant equal to the fair market value of the stock as of that date (less any amount paid for the stock), and the Company will be allowed a corresponding federal income tax deduction at that time, subject to any applicable limitations under Code Section 162(m). Any future appreciation in the stock will be taxable to the participant at capital gains rates. However, if the stock is later forfeited, the participant will not be able to recover the tax previously paid pursuant to the Code Section 83(b) election.

Stock Units

A participant will not recognize income, and the Company will not be allowed a tax deduction, at the time a stock unit award is granted. Upon receipt of shares of common stock (or the equivalent value in cash) in settlement of a stock unit award, a participant will recognize ordinary income equal to the fair market value of the common stock or other property as of that date, and the Company will be allowed a corresponding federal income tax deduction at that time, subject to any applicable limitations under Code Section 162(m).

Cash-Based Awards

A participant will not recognize income, and the Company will not be allowed a tax deduction, at the time a cash-based award is granted (for example, when the performance goals are established). Upon receipt of cash in settlement of the award, a participant will recognize ordinary income equal to the cash received, and the Company will be allowed a corresponding federal income tax deduction at that time, subject to any applicable limitations under Code Section 162(m).

Benefits to Named Executive Officers and Others

Awards under the 2021 Plan are granted at the discretion of the Compensation Committee. Accordingly, future awards under the 2021 Plan are not determinable.

As of the Record Date, ( • ) shares of our common stock have been issued under the 2021 Plan (or remain subject to outstanding awards under the 2021 Plan) since its inception in 2021. The table below shows the number of shares issued, or subject to outstanding awards, under the Plan to the NEOs and the other individuals and groups indicated.

PROPOSAL 4

ADVISORY (NON-BINDING) VOTE ON COMPENSATION

OF NAMED EXECUTIVE OFFICERS

In accordance with the Exchange Act, we are required to include in this proxy statement and present at the Annual Meeting a non-binding shareholder vote to approve the compensation of our named executive officers, as disclosed in this proxy statement pursuant to the compensation rules of the SEC. This proposal, commonly known as a “say-on-pay” proposal, gives shareholders the opportunity to endorse or not endorse the compensation of the Company’s named executive officers as disclosed in this proxy statement. The proposal will be presented at the Annual Meeting in the form of the following resolution:

RESOLVED, that the holders of common stock of the Company approve the compensation of the Company’s named executive officers as disclosed in the Compensation Discussion and Analysis, the compensation tables and related material in the Company’s Proxy Statement for the 2023 Annual Meeting.

This advisory vote will not be binding on the Company’s Board of Directors and may not be construed as overruling a decision by the Board of Directors or creating or implying any additional fiduciary duty on the Board of Directors, nor will it affect any compensation paid or awarded to any executive. The CGC and the Board of Directors will take into account the outcome of the vote when considering future executive compensation arrangements.

The purpose of our compensation policies and procedures is to attract and retain experienced, qualified talent critical to our long-term success and enhancement of shareholder value. Seacoast’s Board of Directors believes that our compensation policies and procedures achieve this objective.

Currently, say-on-pay votes are held by the Company annually, and the next shareholder advisory vote will occur at the 2024 annual meeting of shareholders.

This Proposal 4 requires approval by the affirmative vote of a majority of votes cast at the Annual Meeting.

The Board of Directors unanimously recommends a vote “FOR” Proposal 4.

PROXY STATEMENT 2023

PROPOSAL 5

RATIFICATION OF APPOINTMENT OF INDEPENDENT AUDITOR

The Audit Committee, acting pursuant to authority delegated to it by the Board of Directors, appointed Crowe LLP, an independent registered certified public accounting firm and the Company’s independent auditor for the fiscal year ending December 31, 2022, to serve as the Company’s independent auditor for the fiscal year ending December 31, 2023. Although it is not required to do so, the Board of Directors is submitting the Audit Committee’s appointment of Crowe LLP for ratification by the Company’s shareholders in order to ascertain the views of the shareholders regarding such appointment and as a matter of good corporate practice. If the shareholders should not ratify the appointment of Crowe LLP, the Audit Committee will reconsider the appointment.

Representatives of Crowe LLP will be present at the Annual Meeting and will be given the opportunity to make a statement on behalf of the firm, if they so desire, and will also be available to respond to appropriate questions from shareholders. All shares represented by valid proxies received pursuant to this solicitation and not revoked before they are exercised will be voted in the manner specified therein. If no specification is made, the proxies will be voted for the ratification of the appointment of Crowe LLP for the fiscal year ending December 31, 2023. Ratification of this proposal requires approval by the affirmative vote of a majority of votes cast at the Annual Meeting.

The Board of Directors unanimously recommends a vote “FOR” Proposal 5.

Relationship with Independent Registered Public Accounting Firm

Crowe LLP’s report on Seacoast’s consolidated financial statements for the fiscal year ended December 31, 2022 did not contain an adverse opinion or a disclaimer of opinion, and was not qualified or modified as to uncertainty, audit scope, or accounting principles. Crowe LLP’s report on Seacoast’s internal control over financial reporting expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting as of December 31, 2022. Crowe LLP has advised Seacoast that neither the firm nor any of its partners has any direct or material interest in Seacoast and its subsidiaries except as auditors and independent certified public accountants of Seacoast and its subsidiaries.

Independent Registered Public Accounting Firm’s Fees

The following table shows the fees paid or accrued by the Company for the audit and other services for the fiscal years ended December 31, 2022 and 2021, including expenses:

Tax Fees (3) | $95,846 | $61,000

Also includes aggregate fees billed in 2022 and 2021 for professional services performed in connection with the Company’s filing of certain registration statements and related issuance of consents.

| (3) | Includes tax preparation and compliance activities for the Company and related tax compliance.

| (4) | Includes the aggregate fees for professional services and expenses rendered in connection with the audit of the Company’s retirement savings plan.

OTHER INFORMATION

Certain Transactions and Business Relationships

Related Party Transactions

The Board of Directors recognizes that related party transactions present a heightened risk of conflicts of interest and/or improper valuation (or the perception thereof) and therefore has adopted a Related Party Transaction Policy to guide the Company in connection with all related party transactions. The policy is available on the Company’s website at www.SeacoastBanking.com. The Company defines a related party as:

| ● | any employee, officer, director or director nominee of the Company and/or its subsidiaries;

| ● | a shareholder (or group of affiliated shareholders) beneficially owning in excess of 5% of the Company (or its controlled affiliates);

| ● | a shareholder (or group of affiliated shareholders) with the right to designate a director or board observer to the Board of Directors of the Company and/or any of its subsidiaries;

| ● | an immediate family member of any of the foregoing; and

| ● | an entity which is owned or controlled by someone listed above, or an entity in which someone listed above has a substantial ownership interest or control of such entity.

The policy requires the Audit Committee or a majority of disinterested members of the Board to approve or ratify a transaction between the Company and any related party (including any transactions requiring disclosure under Item 404 of Regulation S-K under the Securities Exchange Act of 1934), other than:

| ● | transactions available on similar terms to all employees or customers generally;

| ● | transactions involving less than $25,000 when aggregated with all similar transactions; and

| ● | loans made by the Bank in the ordinary course of business, on substantially the same terms, including interest rates and collateral, as, and following credit underwriting procedures that are not less stringent than, those prevailing at the time for comparable loans with parties not related to the lender, and not involving more than the normal risk of repayment or presenting other unfavorable features, and in compliance with applicable law, including the Sarbanes Oxley Act of 2002 and Regulation O of the Board of Governors of the Federal Reserve System.

The Audit Committee is currently comprised of five directors, Dennis J. Arczynski, Christopher E. Fogal, Maryann Goebel, Robert J. Lipstein (Chair) and Alvaro J. Monserrat. None of the current Audit Committee members is or has been an officer or employee of Seacoast or its subsidiaries and each is independent.

From time to time, the Company enters into commercial dealings with certain related persons that it considers arms-length and comparable to dealings between unrelated parties. Director H. Gilbert Culbreth, Jr. is the owner of Gilbert Ford automobile dealership. In 2022, Seacoast paid Gilbert Ford $32,526 for a vehicle purchase. The Audit Committee approved this arrangement.

Several of Seacoast’s directors, executive officers and their affiliates, including corporations and firms of which they are directors or officers or in which they and/or their families have an ownership interest, are customers of Seacoast and its subsidiaries. These persons, corporations and firms have had transactions in the ordinary course of business with Seacoast and its subsidiaries, including borrowings, all of which, in the opinion of Seacoast’s management and in accordance with the Bank’s written loan policy, were on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with unaffiliated persons and did not involve more than the normal risk of collectability or present other unfavorable features. Seacoast and its subsidiaries expect to have such transactions on similar terms with their directors, executive officers, and their affiliates in the future.

As a federally insured bank, the Bank is subject to Regulation O, which governs loans to “insiders”, defined as any executive officer, director or principal shareholder of the Company or the Bank, and their related interests. Regulation O limits loans to insiders and requires that the terms and conditions of credits granted to insiders are substantially the same as those extended to other customers of the Bank. The Bank’s written loan policy requires compliance with the provisions of Regulation O.

The aggregate amount of loans outstanding by the Bank to directors, executive officers, and related parties of Seacoast or the Bank as of December 31, 2022, was approximately $425,749, which represented approximately 0.03% of Seacoast’s consolidated shareholders’ equity on that date. Additionally, the Bank had $2,149,373 in unfunded commitments to lend directors and named executive officers at December 31, 2022. These loans were made in the ordinary course of business and they did not involve more than the normal risk of collectability or present other unfavorable features.

Additional Voting Information

Voting at Annual Meeting

Shares represented by valid proxies and voting instruction forms that are received on time will be voted as specified. If you sign and return your proxy card or voting instruction form but do not provide voting instructions, your shares represented by the proxy will be voted as recommended by our Board of Directors as indicated below:

Proposal | Board Recommendation
1 | Election of Directors | FOR ALL
2 | Amendment to the Company’s Amended and Restated Articles of Incorporation | FOR
3 | Amend the Company’s Amended 2021 Incentive Plan | FOR
4 | Advisory Vote on Executive Compensation | FOR
5 | Ratification of Auditor | FOR

If any other matters are properly presented at the Annual Meeting for action, the persons named and acting as proxy will have the discretion to vote for you on these matters in accordance with their best judgment. We do not currently expect that any other matters will be properly presented for action at the Annual Meeting. Each share of common stock is entitled to one vote on each matter properly brought before the meeting.

Record Date

You may vote all common shares that you owned as of the close of business on March 27, 2023, which is the record date for the meeting.

Forms of Ownership of Shares

If you receive more than one proxy card or notice, it means you have multiple holdings. You may own common shares in one or more ways, including:

| ● | Directly in your name as the shareholder of record (which may be held individually, jointly, or another title), including shares purchased through Seacoast’s Dividend Reinvestment and Stock Purchase Plan or restricted stock awards issued to employees under our long-term incentive plans;

| ● | Indirectly through a bank, broker or other nominee in “street name”; or

| ● | Indirectly through Seacoast’s Retirement Savings Plan or Employee Stock Purchase Plan.

If your shares of common stock are registered directly in your name, we are sending the proxy materials directly to you. If you hold our shares in street name, your bank, broker or other nominee is sending proxy materials to you and you must direct them how to vote on your behalf by completing the voting instruction form that accompanies your proxy materials or by following the instructions in the notice you received.

If you are a participant in Seacoast’s Dividend Reinvestment and Stock Purchase Plan, follow the instructions on the Notice or proxy card to provide voting instructions to the trustee. Shares held in your plan account will be combined and voted at the Annual Meeting in the same manner in which you voted those shares registered in your own name either by proxy or in person.

If you are a participant in Seacoast’s Retirement Savings Plan or Employee Stock Purchase Plan, your voting instructions must be received by May 18, 2023 (the “cut-off date”) to allow sufficient time for the trustees to vote. If your voting instructions are received by the cut-off date, your shares in these plans will be voted as directed by you. For the shares in your account in Seacoast’s Retirement Savings Plan, if you do not submit your voting instructions by following the instructions on the Notice or proxy card, then the trustee of the Retirement Savings Plan will vote, or not vote, in its sole discretion, the shares of common stock in your account. For shares held in your account in the Employee Stock Purchase Plan, your shares will not be voted if you do not give voting instructions as to such shares by proxy by the cut-off date. Please follow the instructions on each notice or proxy card to ensure that all of your shares are voted.

Street Name Holders

If you are a beneficial owner and a broker, bank or other nominee is the record holder (which is commonly referred to as holding shares in “street name”), then you received the notice of the Annual Meeting or proxy materials from the record holder. You have the right to direct your broker or nominee how to vote your shares, and such broker or other nominee is required to vote the shares in accordance with your instructions. Your broker or nominee should have given you instructions on how to vote your shares. It will then be the record holder’s responsibility to vote your shares in the manner you direct. Generally, under the rules of various securities exchanges, brokers and other record holders may vote on discretionary or routine matters, but cannot vote on non-routine or non-discretionary matters unless they have received voting instructions from the beneficial holder. We therefore encourage you to provide directions to your broker as to how you want your shares voted on all matters to be brought before the Annual Meeting.

Proposals 1, 2, 3 and 4 are considered non-routine matters, and cannot be voted on by your broker without your instructions. We therefore encourage you to provide directions to your broker as to how you want your shares voted on all matters to be voted on at the meeting. Proposal 5 is considered a routine matter and the only proposal for which your broker or other record holders may vote.

65

PROXY STATEMENT 2023

If your shares are held in street name, you are invited to attend the Annual Meeting; however, you may not vote your shares of common stock held in street name in person at the Annual Meeting unless you request and obtain a power of attorney or other authority from your broker or other nominee who holds your shares and bring it to the Annual Meeting. Even if you plan to attend the Annual Meeting, we ask that you vote in advance of the Annual Meeting in case your plans change.

Revocation of Proxies

If your shares of common stock are registered directly in your name, you may revoke your proxy and change your vote at any time before the polls close at the Annual Meeting. You may do this by:

| ● | timely submitting another proxy via the telephone or internet;

| ● | delivering to Seacoast a written notice bearing a date later than the date of the proxy card, stating that you revoke the proxy, with such written notice to be sent to: 815 Colorado Avenue, P. O. Box 9012, Stuart, Florida 34995, Attention: Corporate Secretary;

| ● | signing and delivering to Seacoast a proxy card relating to the same shares and bearing a later date; or

| ● | attending the meeting and voting in person by written ballot, although attendance at the meeting will not, by itself, revoke a proxy.

Also, please note that if you have voted through your broker, bank or other nominee and you wish to change your vote, you must follow the instructions received from such entity to change your vote.

Quorum and Required Vote

To hold a vote on any proposal, a quorum must be present in person or by proxy at the Annual Meeting. A quorum is a majority of the total votes entitled to be cast by the holders of the outstanding shares of common stock as of the close of business on the Record Date.

In determining whether a quorum exists at the Annual Meeting for purposes of all matters to be voted on, all votes “for” or “against,” as well as all abstentions and broker non-votes, will be counted. A “broker non-vote” occurs when a nominee does not have discretionary voting power with respect to that proposal and has not received instructions from the beneficial owner.

On the Record Date, there were ( • ) shares of common stock issued, outstanding and entitled to be voted, which were held by approximately ( • ) holders of record. Therefore, at least ( • ) shares need to be present at the Annual Meeting or represented by proxy in order for a quorum to exist.

If a quorum is not present at the scheduled time of the Annual Meeting, a majority of the shareholders present or represented by proxy may adjourn the Annual Meeting until a quorum is present. The time and place of the adjourned Annual Meeting will be announced at the time of the adjournment, if any, and no other notice will be given. An adjournment will have no effect on the business that may be conducted at the Annual Meeting. If the Annual Meeting is adjourned more than 120 days after the date fixed for the original Annual Meeting, the Board of Directors must fix a new record date to determine the shareholders entitled to vote at the adjourned Annual Meeting.

Cumulative voting is not permitted. Abstentions and broker non-votes, if any, will not be counted for purposes of determining whether any of the proposals have received sufficient votes for approval, but will count for purposes of determining whether or not a quorum is present. So long as a quorum is present, abstentions and broker non-votes will have no effect on any of the matters presented for a vote at the Annual Meeting.

To elect directors and adopt the other proposals at the 2023 Annual Meeting, the following votes are required:

Proposal | Vote Required | Do abstentions and broker non-votes count as votes cast? | Is broker discretionary voting allowed?
1 | Election of Directors | Plurality vote (1) | No | No
2 | Amendment to the Company’s Amended and Restated Articles of Incorporation | Affirmative vote of two-thirds (66 2/3%) of votes cast | No | No
3 | Amend the Company’s Amended 2021 Incentive Plan | Affirmative vote of a majority of votes cast | No | No
4 | Advisory (Non-binding) Vote on Executive Compensation | Affirmative vote of a majority of votes cast | No | No
5 | Ratification of Auditor | Affirmative vote of a majority of votes cast | No | Yes

| (1) | Under our Bylaws, all elections of directors are decided by plurality vote. However, notwithstanding the plurality standard, in an uncontested election for directors, which is the case for the election under Proposal 1, our Corporate Governance Guidelines provide that if any director nominee receives a greater number of votes “withheld” from his or her election than votes “for” such election, then the director will promptly tender his or her resignation to the Board following certification of the shareholder vote. The CGC would then review and make a recommendation to the Board of Directors as to whether the Board should accept the resignation, and the Board would ultimately decide whether to accept or reject the resignation. If any resignation is accepted by the Board, such resignation will be effective upon acceptance, the Company will disclose its decision-making process regarding the resignation in a Form 8-K furnished to the SEC. In contested elections, the required vote would be a plurality of votes cast and the resignation policy would not apply. Full details of this policy are set forth in our Corporate Governance Guidelines, available on our website at www.SeacoastBanking.com.

Our 2023 Annual Meeting will be held at the Hutchinson Shores Resort: 3793 NE Ocean Blvd, Jensen Beach, FL 34957

Important Note Regarding Virtual Annual Meeting

We intend to hold our annual meeting in person. However, we are sensitive to the public health and travel concerns our shareholders may have and recommendations that public health officials may continue to issue in light of the ongoing coronavirus (COVID-19) pandemic. As a result, we may impose additional procedures or limitations on meeting attendees or may decide to hold the meeting in a different location or solely by means of remote communication (i.e., a virtual-only meeting). We plan to announce any such updates on our proxy website www.proxyvote.com, and we encourage you to check this website prior to the meeting if you plan to attend.

APPENDIX A

INFORMATION REGARDING NON-GAAP FINANCIAL MEASURES

This proxy statement contains financial information determined by methods other than Generally Accepted Accounting Principles (“GAAP”). Management uses these non-GAAP financial measures in its analysis of the Company’s performance and believes these presentations provide useful supplemental information, and a clearer understanding of the Company’s performance. The Company believes the non-GAAP measures enhance investors’ understanding of the Company’s business and performance and if not provided would be requested by the investor community. These measures are also useful in understanding performance trends and facilitate comparisons with the performance of other financial institutions. The limitations associated with operating measures are the risk that persons might disagree as to the appropriateness of items comprising these measures and that different companies might calculate these measures differently. The Company provides reconciliations between GAAP and these non-GAAP measures. These measures should not be considered an alternative to GAAP.

3.1. EFFECTIVE DATE. The Plan will become effective on the date that it is adopted by the Company’s shareholders (the “Effective Date”).

3.2. TERM OF PLAN. Unless earlier terminated as provided herein, the Plan shall continue in effect until the tenth anniversary of the Effective Date or, if the shareholders approve an amendment to the Plan that increases the number of Shares subject to the Plan, the tenth anniversary of the date of such approval.

ADMINISTRATION

4.1. COMMITTEE. The Plan shall be administered by a Committee appointed by the Board (which Committee shall consist of at least two directors) or, at the discretion of the Board from time to time, the Plan may be administered by the Board. It is intended that at least two of the directors appointed to serve on the Committee shall be Independent Directors and that any such members of the Committee who do not so qualify shall abstain from participating in any decision to make or administer Awards that are made to Eligible Participants who at the time of consideration for such Award are persons subject to the short-swing profit rules of Section 16 of the 1934 Act. However, the mere fact that a Committee member shall fail to qualify as an Independent Director or shall fail to abstain from such action shall not invalidate any Award made by the Committee which Award is otherwise validly made under the Plan. The members of the Committee shall be appointed by, and may be changed at any time and from time to time in the discretion of, the Board. Unless and until changed by the Board, the Compensation and Governance Committee of the Board is designated as the Committee to administer the Plan. The Board may reserve to itself any or all of the authority and responsibility of the Committee under the Plan or may act as administrator of the Plan for any and all purposes. To the extent the Board has reserved any authority and responsibility or during any time that the Board is acting as administrator of the Plan, it shall have all the powers and protections of the Committee hereunder, and any reference herein to the Committee (other than in this Section 4.1) shall include the Board. To the extent any action of the Board under the Plan conflicts with actions taken by the Committee, the actions of the Board shall control.

4.2. ACTION AND INTERPRETATIONS BY THE COMMITTEE. For purposes of administering the Plan, the Committee may from time to time adopt rules, regulations, guidelines and procedures for carrying out the provisions and purposes of the Plan and make such other determinations, not inconsistent with the Plan, as the Committee may deem appropriate. The Committee may correct any defect, supply any omission or reconcile any inconsistency in the Plan or in any Award in the manner and to the extent it deems necessary to carry out the intent of the Plan. The Committee’s interpretation of the Plan, any Awards granted under the Plan, any Award Certificate and all decisions and determinations by the Committee with respect to the Plan are final, binding, and conclusive on all parties. Each member of the Committee is entitled to, in good faith, rely or act upon any report or other information furnished to that member by any officer or other employee of the Company or any Affiliate, the Company’s or an Affiliate’s independent certified public accountants, Company counsel or any executive compensation consultant or other professional retained by the Company or the Committee to assist in the administration of the Plan. No member of the Committee will be liable for any good faith determination, act or omission in connection with the Plan or any Award.

4.3. AUTHORITY OF COMMITTEE. Except as provided in Section 4.1 and 4.5 hereof, the Committee has the exclusive power, authority and discretion to:

(a) Grant Awards;

(b) Designate Participants;

(c) Determine the type or types of Awards to be granted to each Participant;

(d) Determine the number of Awards to be granted and the number of Shares or dollar amount to which an Award will relate;

(e) Determine the terms and conditions of any Award granted under the Plan;

(f) Prescribe the form of each Award Certificate, which need not be identical for each Participant;

(g) Decide all other matters that must be determined in connection with an Award;

(h) Establish, adopt or revise any rules, regulations, guidelines or procedures as it may deem necessary or advisable to administer the Plan;

(i) Make all other decisions and determinations that may be required under the Plan or as the Committee deems necessary or advisable to administer the Plan;

(j) Amend the Plan or any Award Certificate as provided herein; and

(k) Adopt such modifications, procedures, and subplans as may be necessary or desirable to comply with provisions of the laws of the United States or any non-U.S. jurisdictions in which the Company or any Affiliate may operate, in order to assure the viability of the benefits of Awards granted to participants located in the United States or such other jurisdictions and to further the objectives of the Plan.

4.4. DELEGATION. The Committee may delegate to one or more of its members or to one or more officers of the Company or an Affiliate or to one or more agents or advisors such administrative duties or powers as it may deem advisable, and the Committee or any individuals to whom it has delegated duties or powers as aforesaid may employ one or more individuals to render advice with respect to any responsibility the Committee or such individuals may have under this Plan. In addition, the Board or the Committee may, by resolution, expressly delegate to a special committee, consisting of one or more directors who may but need not be officers of the Company, the authority, within specified parameters as to the number and terms of Awards, to (i) designate officers and/or employees of the Company or any of its Affiliates to be recipients of Awards under the Plan, and (ii) to determine the number of such Awards to be received by any such Participants; provided, however, that such delegation of duties and responsibilities to an officer of the Company may not be made with respect to the grant of Awards to eligible participants who are subject to Section 16(a) of the 1934 Act at the Grant Date. The acts of such delegates shall be treated hereunder as acts of the Committee and such delegates shall report regularly to the Board and the Committee regarding the delegated duties and responsibilities and any Awards so granted.

4.5. INDEMNIFICATION. Each person who is or shall have been a member of the Committee, or of the Board, or an officer of the Company to whom authority was delegated in accordance with this Article 4 shall be indemnified and held harmless by the Company against and from any loss, cost, liability, or expense that may be imposed upon or reasonably incurred by him or her in connection with or resulting from any claim, action, suit, or proceeding to which he or she may be a party or in which he or she may be involved by reason of any action taken or failure to act under the Plan and against and from any and all amounts paid by him or her in settlement thereof, with the Company’s approval, or paid by him or her in satisfaction of any judgment in any such action, suit, or proceeding against him or her, provided he or she shall give the Company an opportunity, at its own expense, to handle and defend the same before he or she undertakes to handle and defend it on his or her own behalf, unless such loss, cost, liability, or expense is a result of his or her own willful misconduct or except as expressly provided by statute. The foregoing right of indemnification shall not be exclusive of any other rights of indemnification to which such persons may be entitled under the Company’s charter or bylaws, as a matter of law, or otherwise, or any power that the Company may have to indemnify them or hold them harmless.

ARTICLE 5

5.1. NUMBER OF SHARES. Subject to adjustment as provided in Sections 5.2 and Section 14.1, the aggregate number of Shares reserved and available for issuance pursuant to Awards granted under the Plan shall be 3,750,000. The maximum number of Shares that may be issued upon exercise of Incentive Stock Options granted under the Plan shall be 2,250,000. From and after the Effective Date, no further awards shall be granted under the Prior Plan and the Prior Plan shall remain in effect only so long as awards granted thereunder shall remain outstanding.

(a) To the extent that all or a portion of an Award is canceled, terminates, expires, is forfeited or lapses for any reason, including by reason of failure to meet time-based and/or performance-based vesting requirements, any unissued or forfeited Shares originally subject to the Award will be added back to the Plan share reserve and again be available for issuance pursuant to Awards granted under the Plan.

(b) Shares subject to Awards settled in cash will be added back to the Plan share reserve and again be available for issuance pursuant to Awards granted under the Plan.

(c) The full number of Shares subject to an Option shall count against the number of Shares remaining available for issuance pursuant to Awards made under the Plan, even if the exercise price of an Option is satisfied through net-settlement or by delivering Shares to the Company (by either actual delivery or attestation).

(d) The full number of Shares subject to a SAR that is settled in Shares shall count against the number of Shares remaining available for issuance pursuant to Awards made under the Plan (rather than the net number of Shares actually delivered upon exercise).

(e) Shares withheld from an Award to satisfy tax withholding requirements shall count against the number of Shares remaining available for issuance pursuant to Awards granted under the Plan, and Shares delivered by a participant to satisfy tax withholding requirements shall not be added to the Plan share reserve.

(f) Shares repurchased by the Company on the open market with the proceeds of an Option exercise shall not be added to the Plan share reserve.

(g) Substitute Awards granted pursuant to Section 13.10 of the Plan shall not count against the Shares otherwise available for issuance under the Plan under Section 5.1.

(h) Subject to applicable Exchange requirements, shares available under a shareholder-approved plan of a company acquired by the Company (as appropriately adjusted to Shares to reflect the transaction) may be issued under the Plan pursuant to Awards granted to individuals who were not employees of the Company or its Affiliates immediately before such transaction and will not count against the maximum share limitation specified in Section 5.1.

ELIGIBILITY

6.1. GENERAL. Awards may be granted only to Eligible Participants. Incentive Stock Options may be granted only to Eligible Participants who are employees of the Company or a Parent or Subsidiary as defined in Section 424(e) and (f) of the Code.

ARTICLE 7

STOCK OPTIONS

7.1. GENERAL. The Committee is authorized to grant Options to Participants on the following terms and conditions:

(a) EXERCISE PRICE. The exercise price per Share under an Option shall be determined by the Committee, provided that the exercise price for any Option (other than an Option issued as a substitute Award pursuant to Section 13.10) shall not be less than the Fair Market Value as of the Grant Date.

(b) PROHIBITION ON REPRICING. Except as otherwise provided in Article 14, without the prior approval of shareholders of the Company: (i) the exercise price of an Option may not be reduced, directly or indirectly, (ii) an Option may not be cancelled or surrendered in exchange for Options, SARs or other Awards with an exercise or base price that is less than the exercise price of the original Option, (iii) an Option may not be cancelled or surrendered in exchange for other Awards if the current Fair Market Value of the Shares underlying the Option is lower than the exercise price per share of the Option, and (iv) an Option may not be cancelled or surrendered for value (in cash or otherwise) from a Participant if the current Fair Market Value of the Shares underlying the Option is lower than the exercise price per share of the Option.

(c) TIME AND CONDITIONS OF EXERCISE. The Committee shall determine the time or times at which an Option may be exercised in whole or in part, including a provision that an Option that is otherwise exercisable and has an exercise price that is less than the Fair Market Value of the Stock on the last day of its term will be automatically exercised on such final date of the term by means of a “net exercise,” thus entitling the optionee to Shares equal to the intrinsic value of the Option on such exercise date, less the number of Shares required for tax withholding. The Committee shall also determine the performance or other conditions, if any, that must be satisfied before all or part of an Option may be exercised or vested.

(d) PAYMENT. The Committee shall determine the methods by which the exercise price of an Option may be paid, the form of payment, and the methods by which Shares shall be delivered or deemed to be delivered to Participants. As determined by the Committee at or after the Grant Date, payment of the exercise price of an Option may be made in, in whole or in part, in the form of (i) cash or cash equivalents, (ii) delivery (by either actual delivery or attestation) of previously-acquired Shares based on the Fair Market Value of the Shares on the date the Option is exercised, (iii) withholding of Shares from the Option based on the Fair Market Value of the Shares on the date the Option is exercised, (iv) broker-assisted market sales, or (iv) any other “cashless exercise” arrangement.

(e) EXERCISE TERM. Except for Nonstatutory Options granted to Participants outside the United States, no Option granted under the Plan shall be exercisable for more than ten years from the Grant Date.

(f) NO DEFERRAL FEATURE. No Option shall provide for any feature for the deferral of compensation other than the deferral of recognition of income until the exercise or disposition of the Option.

(g) NO DIVIDEND EQUIVALENTS. No Option shall provide for Dividend Equivalents.

7.2. INCENTIVE STOCK OPTIONS. The terms of any Incentive Stock Options granted under the Plan must comply with the requirements of Section 422 of the Code. Without limiting the foregoing, any Incentive Stock Option granted to a Participant who at the Grant Date owns more than 10% of the voting power of all classes of shares of the Company must have an exercise price per Share of not less than 110% of the Fair Market Value per Share on the Grant Date and an Option term of not more than five years. If all of the requirements of Section 422 of the Code (including the above) are not met, the Option shall automatically become a Nonstatutory Stock Option.

(c) TIME AND CONDITIONS OF EXERCISE. The Committee shall determine the time or times at which a SAR may be exercised in whole or in part, including a provision that a SAR that is otherwise exercisable and has a base price that is less than the Fair Market Value of the Stock on the last day of its term will be automatically exercised on such final date of the term, thus entitling the holder to cash or Shares equal to the intrinsic value of the SAR on such exercise date, less the cash or number of Shares required for tax withholding. Except for SARs granted to Participants outside the United States, no SAR shall be exercisable for more than ten years from the Grant Date.

(d) NO DEFERRAL FEATURE. No SAR shall provide for any feature for the deferral of compensation other than the deferral of recognition of income until the exercise or disposition of the SAR.

An Award of Restricted Stock, Restricted Stock Units or Deferred Stock Units shall be evidenced by an Award Certificate setting forth the terms, conditions, and restrictions applicable to the Award.

9.2. ISSUANCE AND RESTRICTIONS. Restricted Stock, Restricted Stock Units or Deferred Stock Units shall be subject to such restrictions on transferability and other restrictions as the Committee may impose (including, for example, limitations on the right to vote Restricted Stock or the right to receive dividends on the Restricted Stock).

Except as otherwise provided in an Award Certificate or any special Plan document governing an Award, a Participant shall have none of the rights of a shareholder with respect to Restricted Stock Units or Deferred Stock Units until such time as Shares of Stock are paid in settlement of such Awards.

9.3 DIVIDENDS ON RESTRICTED STOCK. In the case of Restricted Stock, the Committee may provide that ordinary cash dividends declared on the Shares before they are vested (i) will be forfeited, (ii) will be deemed to have been reinvested in additional Shares or otherwise reinvested (subject to Share availability under Section 5.1 hereof) and subject to the same vesting provisions as provided for the host Award, or (iii) will be credited by the Company to an account for the Participant and accumulated without interest until the date on which the host Award becomes vested, and any dividends accrued with respect to forfeited Restricted Stock will be reconveyed to the Company without further consideration or any act or action by the Participant. In no event shall dividends be paid or distributed until the vesting restrictions of the underlying Award lapse.

9.4. FORFEITURE. Subject to the terms of the Award Certificate and except as otherwise determined by the Committee at the time of the grant of the Award or thereafter, upon termination of Continuous Service during the applicable restriction period or upon failure to satisfy a performance goal during the applicable restriction period, Restricted Stock or Restricted Stock Units that are at that time subject to restrictions shall be forfeited.

ARTICLE 10

PERFORMANCE AWARDS

10.1. GRANT OF PERFORMANCE AWARDS. The Committee is authorized to grant any Award under this Plan, including cash-based Awards, with performance-based vesting criteria, on such terms and conditions as may be selected by the Committee. Any such Awards with performance-based vesting criteria are referred to herein as Performance Awards. The Committee shall have the complete discretion to determine the number of Performance Awards granted to each Participant, subject to Section 5.4, and to designate the provisions of such Performance Awards as provided in Section 4.3. Any Dividend Equivalents granted with respect to a Performance Award shall be subject to Section 11.1.

10.2. PERFORMANCE GOALS. The Committee may establish performance goals for Performance Awards which may be based on any criteria selected by the Committee. Such performance goals may be described in terms of Company-wide objectives or in terms of objectives that relate to the performance of the Participant, an Affiliate or a division, region, department or function within the Company or an Affiliate. If the Committee determines that a change in the business, operations, corporate structure or capital structure of the Company or the manner in which the Company or an Affiliate conducts its business, or other events or circumstances render performance goals to be unsuitable, the Committee may modify such performance goals in whole or in part, as the Committee deems appropriate. If a Participant is promoted, demoted or transferred to a different business unit or function during a performance period, the Committee may determine that the performance goals or performance period are no longer appropriate and may (i) adjust, change or eliminate the performance goals or the applicable performance period as it deems appropriate to make such goals and period comparable to the initial goals and period, or (ii) make a cash payment to the participant in an amount determined by the Committee.

ARTICLE 11

DIVIDEND EQUIVALENTS

11.1. GRANT OF DIVIDEND EQUIVALENTS. The Committee is authorized to grant Dividend Equivalents with respect to Full-Value Awards granted hereunder, subject to such terms and conditions as may be selected by the Committee. Dividend Equivalents shall entitle the Participant to receive payments equal to ordinary cash dividends with respect to all or a portion of the number of Shares subject to a Full-Value Award, as determined by the Committee. The Committee may provide that Dividend Equivalents (i) will be deemed to have been reinvested in additional Shares or otherwise reinvested (subject to Share availability under Section 5.1 hereof) and subject to the same vesting provisions as provided for the host Award, or (ii) be credited by the Company to an account for the Participant and accumulated without interest until the date on which the host Award becomes vested, and, in either case, any Dividend Equivalents accrued with respect to forfeited Awards will be reconveyed to the Company without further consideration or any act or action by the Participant. In no event shall dividends be paid or distributed until the vesting restrictions of the underlying Award lapse.

ARTICLE 12

STOCK OR OTHER STOCK-BASED AWARDS

12.1. GRANT OF STOCK OR OTHER STOCK-BASED AWARDS. The Committee is authorized, subject to limitations under applicable law, to grant to Participants such other Awards that are payable in, valued in whole or in part by reference to, or otherwise based on or related to Shares, as deemed by the Committee to be consistent with the purposes of the Plan, including without limitation Shares awarded purely as a “bonus” and not subject to any restrictions or conditions, convertible or exchangeable debt securities, other rights convertible or exchangeable into Shares, and Awards valued by reference to book value per Share (or net asset value per Share) or the value of securities of or the performance of specified Parents or Subsidiaries. The Committee shall determine the terms and conditions of such Awards. Any Dividend Equivalents granted with respect to an Award under this Section 12.1 shall be subject to Section 11.1.

In addition, payment of Awards may include such terms, conditions, restrictions and/or limitations, if any, as the Committee deems appropriate, including, in the case of Awards paid in the form of Stock, restrictions on transfer and forfeiture provisions. Further, payment of Awards may be made in the form of a lump sum, or in installments, as determined by the Committee.

13.3. LIMITS ON TRANSFER. No right or interest of a Participant in any unexercised or restricted Award may be pledged, encumbered, or hypothecated to or in favor of any party other than the Company or an Affiliate, or shall be subject to any lien, obligation, or liability of such Participant to any other party other than the Company or an Affiliate. No unexercised or restricted Award shall be assignable or transferable by a Participant other than by will or the laws of descent and distribution; provided, however, that the Committee may (but need not) permit other transfers (other than transfers for value) where the Committee concludes that such transferability (i) does not result in accelerated taxation, (ii) does not cause any Option intended to be an Incentive Stock Option to fail to be described in Code Section 422(b), and (iii) is otherwise appropriate and desirable, taking into account any factors deemed relevant, including without limitation, state or federal tax or securities laws applicable to transferable Awards.

13.4. BENEFICIARIES. Notwithstanding Section 13.3, a Participant may, in the manner determined by the Committee, designate a beneficiary to exercise the rights of the Participant and to receive any distribution with respect to any Award upon the Participant’s death. A beneficiary, legal guardian, legal representative, or other person claiming any rights under the Plan is subject to all terms and conditions of the Plan and any Award Certificate applicable to the Participant, except to the extent the Plan and Award Certificate otherwise provide, and to any additional restrictions deemed necessary or appropriate by the Committee.

13.5. STOCK TRADING RESTRICTIONS. All Stock issuable under the Plan is subject to any stop-transfer orders and other restrictions as the Committee deems necessary or advisable to comply with federal or state securities laws, rules and regulations and the rules of any Exchange or automated quotation system on which the Stock is listed, quoted, or traded. The Committee may place legends on any Stock certificate or issue instructions to the transfer agent to reference restrictions applicable to the Stock.

13.6 ACCELERATION UPON DEATH OR DISABILITY. Except as otherwise provided in the Award Certificate or any special Plan document governing an Award, upon the termination of a person’s Continuous Service by reason of death or Disability:

(i) each that Participant’s outstanding Options and SARs, or the portions of such outstanding Options and SARs, as applicable, that are solely subject to time-based vesting requirements shall become vested and fully exercisable as of the date of termination, and shall thereafter remain exercisable for a period of one (1) year or until the earlier expiration of the original term of the Option or SAR;

(ii) each of that Participant’s other outstanding Awards, or the portions of such other outstanding Awards, as applicable, that are solely subject to time-based vesting restrictions shall become vested, and such restrictions shall lapse as of the date of termination; and

(iii) the payout opportunities attainable under each of that Participant’s outstanding Options, SARs and other Awards, or the portions of such outstanding Options, SARs and other Awards, as applicable, that are solely subject to performance-vesting requirements or restrictions shall be deemed to have been earned as of the date of termination as follows:

(A) if the date of termination occurs during the first half of the applicable performance period, all relevant performance goals will be deemed to have been achieved at the “target” level, and

(B) if the date of termination occurs during the second half of the applicable performance period, then all relevant performance goals will be deemed to have been achieved at the “target” level or, if greater, the actual level of achievement of all relevant performance goals against target will be measured as of the end of the calendar quarter immediately preceding the date of termination.

To the extent that this provision causes Incentive Stock Options to exceed the dollar limitation set forth in Code Section 422(d), the excess Options shall be deemed to be Nonstatutory Stock Options.

13.7. EFFECT OF A CHANGE IN CONTROL. The provisions of this Section 13.7 shall apply in the case of a Change in Control, unless otherwise provided in the Award Certificate or any special Plan document or separate agreement with a Participant governing an Award.

(a) Awards Assumed or Substituted by Surviving Entity. With respect to Awards assumed by the Surviving Entity or otherwise equitably converted or substituted in connection with a Change in Control: if within two years after the effective date of the Change in Control, a Participant’s employment is terminated without Cause or the Participant resigns for Good Reason, then (i) all of that Participant’s outstanding Options, SARs and other Awards in the nature of rights that may be exercised shall become fully exercisable, (ii) all time-based vesting restrictions on his or her outstanding Awards shall lapse, and (iii) the payout level under all of that Participant’s performance-based Awards that were outstanding immediately prior to effective time of the Change in Control shall be determined and deemed to have been earned as of the date of termination based upon (A) an assumed achievement of all relevant performance goals at the “target” level if the date of termination occurs during the first half of the applicable performance period, or (B) the actual level of achievement of all relevant performance goals against target (measured as of the end of the calendar quarter immediately preceding the date of termination), if the date of termination occurs during the second half of the applicable performance period, and, in either such case, there shall be a pro rata payout to such Participant within sixty (60) days following the date of termination of employment (unless a later date is required by Section 16.3 hereof), based upon the length of time within the performance period that has elapsed prior to the date of termination of employment. With regard to each Award, a Participant shall not be considered to have resigned for Good Reason unless either (i) the Award Certificate includes such provision or (ii) the Participant is party to an employment, severance or similar agreement with the Company or an Affiliate that includes provisions in which the Participant is permitted to resign for Good Reason. Any Awards shall thereafter continue or lapse in accordance with the other provisions of the Plan and the Award Certificate. To the extent that this provision causes Incentive Stock Options to exceed the dollar limitation set forth in Code Section 422(d), the excess Options shall be deemed to be Nonstatutory Stock Options.

SEACOAST BANKING CORPORATION OF FLORIDA

(b) Awards not Assumed or Substituted by Surviving Entity. Upon the occurrence of a Change in Control, and except with respect to any Awards assumed by the Surviving Entity or otherwise equitably converted or substituted in connection with the Change in Control in a manner approved by the Committee or the Board: (i) outstanding Options, SARs, and other Awards in the nature of rights that may be exercised shall become fully exercisable, (ii) time-based vesting restrictions on outstanding Awards shall lapse, and (iii) the target payout opportunities attainable under outstanding performance-based Awards shall be deemed to have been fully earned as of the effective date of the Change in Control based upon (A) an assumed achievement of all relevant performance goals at the “target” level if the Change in Control occurs during the first half of the applicable performance period, or (B) the greater of the “target” level or the actual level of achievement of all relevant performance goals against target measured as of the date of the Change in Control, if the Change in Control occurs during the second half of the applicable performance period. Any Awards shall thereafter continue or lapse in accordance with the other provisions of the Plan and the Award Certificate. To the extent that this provision causes Incentive Stock Options to exceed the dollar limitation set forth in Code Section 422(d), the excess Options shall be deemed to be Nonstatutory Stock Options.

13.8. ACCELERATION FOR OTHER REASONS. Regardless of whether an event has occurred as described in Section 13.6 or 13.7 above, the Committee may in its sole discretion at any time determine that, upon the termination of service of a Participant, or the occurrence of a Change in Control, all or a portion of such Participant’s Options, SARs and other Awards in the nature of rights that may be exercised shall become fully or partially vested and exercisable, that all or a part of the restrictions on all or a portion of the Participant’s outstanding Awards shall lapse, and/or that any performance-based criteria with respect to any Awards held by that Participant shall be deemed to be wholly or partially satisfied, in each case, as of such date as the Committee may, in its sole discretion, declare. The Committee may provide for different treatment among Participants and among Awards granted to a Participant in exercising its discretion pursuant to this Section 13.8.

13.9. FORFEITURE EVENTS. Awards under the Plan shall be subject to any compensation recoupment policy that the Company may adopt from time to time that is applicable by its terms to the Participant. In addition, the Committee may specify in an Award Certificate that the Participant’s rights, payments and benefits with respect to an Award shall be subject to reduction, cancellation, forfeiture or recoupment upon the occurrence of certain specified events, in addition to any otherwise applicable vesting or performance conditions of an Award. Such events may include, but shall not be limited to, (i) termination of employment for cause, (ii) violation of material Company or Affiliate policies, (iii) breach of noncompetition, confidentiality or other restrictive covenants that may apply to the Participant, (iv) other conduct by the Participant that is detrimental to the business or reputation of the Company or any Affiliate, or (v) a later determination that the vesting of, or amount realized from, a Performance Award was based on materially inaccurate financial statements or any other materially inaccurate performance metric criteria, whether or not the Participant caused or contributed to such material inaccuracy. Nothing contained herein or in any Award Certificate prohibits the Participant from: (1) reporting possible violations of federal law or regulations, including any possible securities laws violations, to any governmental agency or entity; (2) making any other disclosures that are protected under the whistleblower provisions of federal law or regulations; or (3) otherwise fully participating in any federal whistleblower programs, including but not limited to any such programs managed by the U.S. Securities and Exchange.

13.10. SUBSTITUTE AWARDS. The Committee may grant Awards under the Plan in substitution for stock and stock-based awards held by employees of another entity who become employees of the Company or an Affiliate as a result of a merger or consolidation of the former employing entity with the Company or an Affiliate or the acquisition by the Company or an Affiliate of property or stock of the former employing corporation. The Committee may direct that the substitute awards be granted on such terms and conditions as the Committee considers appropriate in the circumstances.

ARTICLE 14

CHANGES IN CAPITAL STRUCTURE

14.1. MANDATORY ADJUSTMENTS. In the event of a nonreciprocal transaction between the Company and its shareholders that causes the per-share value of the Stock to change (including, without limitation, any stock dividend, stock split, reverse stock split, spin-off, rights offering, or large nonrecurring cash dividend), the authorization limits under Section 5.1 and Section 5.4 shall be adjusted proportionately, and the Committee shall make such adjustments to the Plan and Awards as it deems necessary, in its sole discretion, to prevent dilution or enlargement of rights immediately resulting from such transaction. Action by the Committee may include: (i) adjustment of the number and kind of shares that may be delivered under the Plan; (ii) adjustment of the number and kind of shares subject to outstanding Awards; (iii) adjustment of the exercise price of outstanding Awards or the measure to be used to determine the amount of the benefit payable on an Award; and (iv) any other adjustments that the Committee determines to be equitable. Notwithstanding the foregoing, the Committee shall not make any adjustments to outstanding Options or SARs that would constitute a modification or substitution of the stock right under Treas. Reg. Section 1.409A-1(b)(5)(v) that would be treated as the grant of a new stock right or change in the form of payment for purposes of Code Section 409A. Without limiting the foregoing, in the event of a subdivision of the outstanding Stock (stock-split), a declaration of a dividend payable in Shares, or a combination or consolidation of the outstanding Stock into a lesser number of Shares, the authorization limits under Section 5.1 and Section 5.4 shall automatically be adjusted proportionately, and the Shares then subject to each Award shall automatically, without the necessity for any additional action by the Committee, be adjusted proportionately without any change in the aggregate purchase price therefor.

14.2 DISCRETIONARY ADJUSTMENTS. Upon the occurrence or in anticipation of any corporate event or transaction involving the Company (including, without limitation, any merger, reorganization, recapitalization, combination or exchange of shares, or any transaction described in Section 14.1), the Committee may, in its sole discretion, provide (i) that Awards will be settled in cash rather than Stock, (ii) that Awards will become immediately vested and non-forfeitable and exercisable (in whole or in part) and will expire after a designated period of time to the extent not then exercised, (iii) that Awards will be assumed by another party to a transaction or otherwise be equitably converted or substituted in connection with such transaction, (iv) that outstanding Awards may be settled by payment in cash or cash equivalents equal to the excess of the fair market value of the underlying Stock, as of a specified date associated with the transaction (or the per-shares transaction price), over the exercise or base price of the Award, (v) that performance targets and performance periods for Performance Awards will be modified, or (vi) any combination of the foregoing. The Committee’s determination need not be uniform and may be different for different Participants whether or not such Participants are similarly situated.

79

PROXY STATEMENT 2023

14.3 GENERAL. Any discretionary adjustments made pursuant to this Article 14 shall be subject to the provisions of Section 15.2. To the extent that any adjustments made pursuant to this Article 14 cause Incentive Stock Options to cease to qualify as Incentive Stock Options, such Options shall be deemed to be Nonstatutory Stock Options.

ARTICLE 15

AMENDMENT, MODIFICATION AND TERMINATION

15.1. AMENDMENT, MODIFICATION AND TERMINATION. The Board or the Committee may, at any time and from time to time, amend, modify or terminate the Plan without shareholder approval; provided, however, that if an amendment to the Plan would, in the reasonable opinion of the Board or the Committee, either (i) materially increase the number of Shares available under the Plan (other than pursuant to Article 14), (ii) expand the types of awards under the Plan, (iii) materially expand the class of participants eligible to participate in the Plan, (iv) materially extend the term of the Plan, or (v) otherwise constitute a material change requiring shareholder approval under applicable laws, policies or regulations or the applicable listing or other requirements of an Exchange, then such amendment shall be subject to shareholder approval; and provided, further, that the Board or Committee may condition any other amendment or modification on the approval of shareholders of the Company for any reason, including by reason of such approval being necessary or deemed advisable (i) to comply with the listing or other requirements of an Exchange, or (ii) to satisfy any other tax, securities or other applicable laws, policies or regulations. Except as otherwise provided in Section 14.1, without the prior approval of the shareholders of the Company, the Plan may not be amended to permit: (i) the exercise price or base price of an Option or SAR to be reduced, directly or indirectly, (ii) an Option or SAR to be cancelled in exchange for cash, other Awards, or Options or SARs with an exercise or base price that is less than the exercise price or base price of the original Option or SAR, or otherwise, or (iii) the Company to repurchase an Option or SAR for value (in cash or otherwise) from a Participant if the current Fair Market Value of the Shares underlying the Option or SAR is lower than the exercise price or base price per share of the Option or SAR.

15.2. AWARDS PREVIOUSLY GRANTED. At any time and from time to time, the Committee may amend, modify or terminate any outstanding Award without approval of the Participant; provided, however:

(a) Subject to the terms of the applicable Award Certificate, such amendment, modification or termination shall not, without the Participant’s consent, reduce or diminish the value of such Award;

(b) Except as otherwise provided in Article 14, without the prior approval of the shareholders of the Company: (i) the exercise price or base price of an Option or SAR may not be reduced, directly or indirectly, (ii) an Option or SAR may not be cancelled in exchange for Options, SARs or other Awards with an exercise or base price that is less than the exercise price or base price of the original Option or SAR, or otherwise, and (iii) the Company may not repurchase an Option or SAR for value (in cash or otherwise) from a Participant if the current Fair Market Value of the Shares underlying the Option or SAR is lower than the exercise price or base price per share of the Option or SAR; and

(c) No termination, amendment, or modification of the Plan shall adversely affect any Award previously granted under the Plan, without the written consent of the Participant affected thereby.

15.3. COMPLIANCE AMENDMENTS. Notwithstanding anything in the Plan or in any Award Certificate to the contrary, the Board may amend the Plan or an Award Certificate, to take effect retroactively or otherwise, as deemed necessary or advisable for the purpose of conforming the Plan or Award Certificate to any present or future law relating to plans of this or similar nature (including, but not limited to, Section 409A of the Code), and to the administrative regulations and rulings promulgated thereunder. By accepting an Award under this Plan, a Participant agrees to any amendment made pursuant to this Section 15.3 to any Award granted under the Plan without further consideration or action.

ARTICLE 16

GENERAL PROVISIONS

16.1. RIGHTS OF PARTICIPANTS.

(a) No Participant or any Eligible Participant shall have any claim to be granted any Award under the Plan. Neither the Company, its Affiliates nor the Committee is obligated to treat Participants or Eligible Participants uniformly, and determinations made under the Plan may be made by the Committee selectively among Eligible Participants who receive, or are eligible to receive, Awards (whether or not such Eligible Participants are similarly situated).

(b) Nothing in the Plan, any Award Certificate or any other document or statement made with respect to the Plan, shall interfere with or limit in any way the right of the Company or any Affiliate to terminate any Participant’s employment or status as an officer, or any Participant’s service as a director, at any time, nor confer upon any Participant any right to continue as an employee, officer, or director of the Company or any Affiliate, whether for the duration of a Participant’s Award or otherwise.

(c) Neither an Award nor any benefits arising under this Plan shall constitute an employment contract with the Company or any Affiliate and, accordingly, subject to Article 15, this Plan and the benefits hereunder may be terminated at any time in the sole and exclusive discretion of the Committee without giving rise to any liability on the part of the Company or any of its Affiliates.

(d) No Award gives a Participant any of the rights of a shareholder of the Company unless and until Shares are in fact issued to such person in connection with such Award.

SEACOAST BANKING CORPORATION OF FLORIDA

16.2. WITHHOLDING. The Company or any Affiliate shall have the authority and the right to deduct or withhold, or require a Participant to remit to the Company or such Affiliate, an amount sufficient to satisfy federal, state, local and foreign taxes (including the Participant’s FICA obligation) required by law to be withheld with respect to any exercise, lapse of restriction or other taxable event arising as a result of the Plan. The obligations of the Company under the Plan will be conditioned on such payment or arrangements and the Company or such Affiliate will, to the extent permitted by law, have the right to deduct any such taxes from any payment of any kind otherwise due to the Participant. Unless otherwise determined by the Committee at the time the Award is granted or thereafter, any such withholding requirement may be satisfied, in whole or in part, by withholding from the Award Shares having a Fair Market Value on the date of withholding equal to the amount required to be withheld in accordance with applicable tax requirements, all in accordance with such procedures as the Committee approves (which procedures may permit withholding up to the maximum individual statutory rate in the applicable jurisdiction as may be permitted under then-current accounting principles to qualify for equity classification). All such elections shall be subject to any restrictions or limitations that the Committee, in its sole discretion, deems appropriate.

16.3. SPECIAL PROVISIONS RELATED TO SECTION 409A OF THE CODE.

(a) General. It is intended that the payments and benefits provided under the Plan and any Award shall either be exempt from the application of, or comply with, the requirements of Section 409A of the Code. The Plan and all Award Certificates shall be construed in a manner that effects such intent. Nevertheless, the tax treatment of the benefits provided under the Plan or any Award is not warranted or guaranteed. Neither the Company, its Affiliates nor their respective directors, officers, employees or advisers (other than in his or her capacity as a Participant) shall be held liable for any taxes, interest, penalties or other monetary amounts owed by any Participant or other taxpayer as a result of the Plan or any Award.

(b) Definitional Restrictions. Notwithstanding anything in the Plan or in any Award Certificate to the contrary, to the extent that any amount or benefit that would constitute non-exempt “deferred compensation” for purposes of Section 409A of the Code (“Non-Exempt Deferred Compensation”) would otherwise be payable or distributable, or a different form of payment (e.g., lump sum or installment) of such Non-Exempt Deferred Compensation would be effected, under the Plan or any Award Certificate by reason of the occurrence of a Change in Control, or the Participant’s Disability or separation from service, such Non-Exempt Deferred Compensation will not be payable or distributable to the Participant, and/or such different form of payment will not be effected, by reason of such circumstance unless the circumstances giving rise to such Change in Control, Disability or separation from service meet any description or definition of “change in control event”, “disability” or “separation from service”, as the case may be, in Section 409A of the Code and applicable regulations (without giving effect to any elective provisions that may be available under such definition). This provision does not affect the dollar amount or prohibit the vesting of any Award upon a Change in Control, Disability or separation from service, however defined. If this provision prevents the payment or distribution of any amount or benefit, or the application of a different form of payment of any amount or benefit, such payment or distribution shall be made at the time and in the form that would have applied absent the non-409A-conforming event.

(c) Allocation among Possible Exemptions. If any one or more Awards granted under the Plan to a Participant could qualify for any separation pay exemption described in Treas. Reg. Section 1.409A-1(b)(9), but such Awards in the aggregate exceed the dollar limit permitted for the separation pay exemptions, the Company (acting through the Committee or the Head of Human Resources) shall determine which Awards or portions thereof will be subject to such exemptions.

(d) Six-Month Delay in Certain Circumstances. Notwithstanding anything in the Plan or in any Award Certificate to the contrary, if any amount or benefit that would constitute Non-Exempt Deferred Compensation would otherwise be payable or distributable under this Plan or any Award Certificate by reason of a Participant’s separation from service during a period in which the Participant is a Specified Employee (as defined below), then, subject to any permissible acceleration of payment by the Committee under Treas. Reg. Section 1.409A-3(j)(4)(ii) (domestic relations order), (j)(4)(iii) (conflicts of interest), or (j)(4)(vi) (payment of employment taxes):

(i) the amount of such Non-Exempt Deferred Compensation that would otherwise be payable during the six-month period immediately following the Participant’s separation from service will be accumulated through and paid or provided on the first day of the seventh month following the Participant’s separation from service (or, if the Participant dies during such period, within 30 days after the Participant’s death) (in either case, the “Required Delay Period”); and

(ii) the normal payment or distribution schedule for any remaining payments or distributions will resume at the end of the Required Delay Period.

For purposes of this Plan, the term “Specified Employee” has the meaning given such term in Code Section 409A and the final regulations thereunder; provided, however, that, as permitted in such final regulations, the Company’s Specified Employees and its application of the six-month delay rule of Code Section 409A(a)(2)(B)(i) shall be determined in accordance with rules adopted by the Board or any committee of the Board, which shall be applied consistently with respect to all nonqualified deferred compensation arrangements of the Company, including this Plan.

(e) Installment Payments. If, pursuant to an Award, a Participant is entitled to a series of installment payments, such Participant’s right to the series of installment payments shall be treated as a right to a series of separate payments and not to a single payment. For purposes of the preceding sentence, the term “series of installment payments” has the meaning provided in Treas. Reg. Section 1.409A-2(b)(2)(iii) (or any successor thereto).

(f) Timing of Release of Claims. Whenever an Award conditions a payment or benefit on the Participant’s execution and non-revocation of a release of claims, such release must be executed and all revocation periods shall have expired within 60 days after the date of termination of the Participant’s employment; failing which such payment or benefit shall be forfeited. If such payment or benefit is exempt from Section 409A of the Code, the Company may elect to make or commence payment at any time during such 60-day period. If such payment or benefit constitutes Non-Exempt Deferred Compensation, then, subject to subsection (d) above, (i) if such 60-day period begins and ends in a single calendar year, the Company may make or commence payment at any time during such period at its discretion, and (ii) if such 60-day period begins in one calendar year and ends in the next calendar year, the payment shall be made or commence during the second such calendar year (or any later date specified for such payment under the applicable Award), even if such signing and non-revocation of the release occur during the first such calendar year included within such 60-day period. In other words, a Participant is not permitted to influence the calendar year of payment based on the timing of signing the release.

81

PROXY STATEMENT 2023

(g) Permitted Acceleration. The Company shall have the sole authority to make any accelerated distribution permissible under Treas. Reg. Section 1.409A-3(j)(4) to Participants of deferred amounts, provided that such distribution(s) meets the requirements of Treas. Reg. Section 1.409A-3(j)(4).

16.4. UNFUNDED STATUS OF AWARDS. The Plan is intended to be an “unfunded” plan for incentive and deferred compensation. With respect to any payments not yet made to a Participant pursuant to an Award, nothing contained in the Plan or any Award Certificate shall give the Participant any rights that are greater than those of a general creditor of the Company or any Affiliate. In its sole discretion, the Committee may authorize the creation of grantor trusts or other arrangements to meet the obligations created under the Plan to deliver Shares or payments in lieu of Shares or with respect to Awards. This Plan is not intended to be subject to ERISA.

16.5. RELATIONSHIP TO OTHER BENEFITS. No payment under the Plan shall be taken into account in determining any benefits under any pension, retirement, savings, profit sharing, group insurance, welfare or benefit plan of the Company or any Affiliate unless provided otherwise in such other plan. Nothing contained in the Plan will prevent the Company from adopting other or additional compensation arrangements, subject to shareholder approval if such approval is required; and such arrangements may be either generally applicable or applicable only in specific cases.

16.6. EXPENSES. The expenses of administering the Plan shall be borne by the Company and its Affiliates.

16.7. TITLES AND HEADINGS. The titles and headings of the Sections in the Plan are for convenience of reference only, and in the event of any conflict, the text of the Plan, rather than such titles or headings, shall control.

16.8. GENDER AND NUMBER. Except where otherwise indicated by the context, any masculine term used herein also shall include the feminine; the plural shall include the singular and the singular shall include the plural.

16.9. FRACTIONAL SHARES. No fractional Shares shall be issued and the Committee shall determine, in its discretion, whether cash shall be given in lieu of fractional Shares or whether such fractional Shares shall be eliminated by rounding up or down.

16.10. GOVERNMENT AND OTHER REGULATIONS.

(a) Notwithstanding any other provision of the Plan, no Participant who acquires Shares pursuant to the Plan may, during any period of time that such Participant is an affiliate of the Company (within the meaning of the rules and regulations of the Securities and Exchange Commission under the 1933 Act), sell such Shares, unless such offer and sale is made (i) pursuant to an effective registration statement under the 1933 Act, which is current and includes the Shares to be sold, or (ii) pursuant to an appropriate exemption from the registration requirement of the 1933 Act, such as that set forth in Rule 144 promulgated under the 1933 Act.

(b) Notwithstanding any other provision of the Plan, if at any time the Committee shall determine that the registration, listing or qualification of the Shares covered by an Award upon any Exchange or under any foreign, federal, state or local law or practice, or the consent or approval of any governmental regulatory body, is necessary or desirable as a condition of, or in connection with, the granting of such Award or the purchase or receipt of Shares thereunder, no Shares may be purchased, delivered or received pursuant to such Award unless and until such registration, listing, qualification, consent or approval shall have been effected or obtained free of any condition not acceptable to the Committee. Any Participant receiving or purchasing Shares pursuant to an Award shall make such representations and agreements and furnish such information as the Committee may request to assure compliance with the foregoing or any other applicable legal requirements. The Company shall not be required to issue or deliver any certificate or certificates for Shares under the Plan prior to the Committee’s determination that all related requirements have been fulfilled. The Company shall in no event be obligated to register any securities pursuant to the 1933 Act or applicable state or foreign law or to take any other action in order to cause the issuance and delivery of such certificates to comply with any such law, regulation or requirement.

16.11. GOVERNING LAW. To the extent not governed by federal law, the Plan and all Award Certificates shall be construed in accordance with and governed by the laws of the State of Florida.

16.12. SEVERABILITY. In the event that any provision of this Plan is found to be invalid or otherwise unenforceable under any applicable law, such invalidity or unenforceability will not be construed as rendering any other provisions contained herein as invalid or unenforceable, and all such other provisions will be given full force and effect to the same extent as though the invalid or unenforceable provision was not contained herein.

16.13. NO LIMITATIONS ON RIGHTS OF COMPANY. The grant of any Award shall not in any way affect the right or power of the Company to make adjustments, reclassification or changes in its capital or business structure or to merge, consolidate, dissolve, liquidate, sell or transfer all or any part of its business or assets. The Plan shall not restrict the authority of the Company, for proper corporate purposes, to draft or assume awards, other than under the Plan, to or with respect to any person. If the Committee so directs, the Company may issue or transfer Shares to an Affiliate, for such lawful consideration as the Committee may specify, upon the condition or understanding that the Affiliate will transfer such Shares to a Participant in accordance with the terms of an Award granted to such Participant and specified by the Committee pursuant to the provisions of the Plan.
