A NOTE FROM OUR CHAIRMAN AND CEO

TO OUR FELLOW SHAREHOLDERS,

CUSTOMERS, PARTNERS AND FRIENDS:

![](sbcf-20260410_g3.gif)

2025 was a transformative year for Seacoast—one that expanded our franchise, deployed excess

capital to enhance our earnings power, and positioned the Company to deliver stronger and more

durable shareholder returns. We advanced our strategy on multiple fronts, including completing two

strategically important acquisitions, building strong organic momentum, investing in technology

and automation, and maintaining disciplined balance sheet stewardship. Most importantly, we

executed these initiatives while remaining true to the values that have defined Seacoast for nearly

a century: relationship-based community banking, prudent risk management, and a culture

grounded in service and accountability.

We delivered strong financial performance in 2025. Highlights included above-peer organic loan

growth of 9%, driven by continued investment in our commercial banking franchise and the

continued maturation of our teams. Disciplined deposit cost management resulted in a below-peer

cost of deposits and drove a 10% expansion in net interest margin compared to the prior year. We

also improved operating leverage, with our adjusted efficiency ratio improving by more than five

points to 58%. In total, our adjusted pre-tax, pre-provision earnings increased 45% from the prior

year.

These results were achieved while maintaining industry-leading capital and liquidity, including a

Tier 1 capital ratio of 14.5% and a loan-to-deposit ratio of 78% at year-end. Our strategic focus on

relationship-based banking continues to produce a strong, low-cost core funding franchise,

supporting consistent credit discipline. We exercised that discipline during a volatile operating

environment in 2023, allowing capital to build and position Seacoast to pursue future strategic

opportunities. In 2025, we deployed our excess capital to expand our franchise in Florida. We

continue to have meaningful capital flexibility and strategic optionality—supporting organic growth,

continued investment in talent and technology, and opportunistic capital actions that can enhance

long-term shareholder value.

Building a Stronger, More Valuable Franchise

A defining feature of 2025 was the completion of two exceptional acquisitions that materially

strengthened our competitive position and expanded our long-term growth runway.

First, we completed the acquisition of Villages Bancorporation, Inc., which added a leading market

position and a high-quality, low-cost deposit franchise in one of the fastest-growing MSAs in the

country. Our partnership with The Villages® community is truly unique. Its distinctive service

model aligns closely with Seacoast's customer-centric culture while adding meaningful scale to our

community banking and mortgage businesses. Importantly, this partnership creates a decade-plus

deposit growth opportunity that provides stable funding to profitably grow our commercial bank

over time. We believe the combination of Seacoast's relationship-based approach, product breadth,

and strong commercial banking team with this exceptional deposit franchise creates a compelling

platform for sustained, durable earnings performance.

Second, we completed the acquisition and conversion of Heartland Bancshares, Inc., expanding our

presence in Central Florida. Heartland brought deep community roots and trusted relationships—

qualities that align closely with Seacoast's operating philosophy. By combining Heartland's local

strengths with Seacoast's broader capabilities and scale, we believe we are better positioned to

serve customers, deepen relationships, and accelerate profitable growth in this market.

These transactions were executed with a disciplined approach to diligence, integration, and cultural

alignment, supported by experience gained across 16 prior acquisitions. Integration is where value

is created, and we entered each transaction with a clear plan, strong governance, and a focus on

bringing teams together around a shared mission and a consistent customer experience. We believe

we are building an organization with greater scale, stronger market positions, and improved

investment capacity—while preserving the local decision-making and relationship focus that

distinguish Seacoast.

Discipline That Supports Improved Shareholder Returns

Our strategy is designed to produce a consistent outcome: stronger profitability and improved

shareholder returns across economic cycles. In 2025, we continued to manage the balance sheet

with discipline—protecting capital, bolstering liquidity, and maintaining underwriting standards that

![SCB-Large-Sail-Teal-15.gif](sbcf-20260410_g10.gif)

SHAREHOLDER

![](sbcf-20260410_g9.gif)

prioritize long-term asset quality over short-term volume. In an environment where prudent risk

management remains a competitive advantage, our commitment to consistent credit discipline and

balance sheet strength is unchanged.

We also remain focused on efficiency and operating leverage. As we scale the franchise—organically

and through acquisitions—we expect to benefit from operating leverage from fixed-cost

investments as we grow further as a mid-sized bank. These benefits can support greater

investment capacity for growth, automation, and innovation.

A Culture That Sustains Performance

Our performance in 2025 was made possible by the commitment of our associates and the

strength of Seacoast's culture. Recognition during the year—including being named among

American Banker's "Best Banks to Work For" for the sixth consecutive year, earning Great Place To

Work® Certification for the third year in a row, and being recognized on Fortune's Best Workplaces

for Women™ 2025 list for the third consecutive year—reflects the values, teamwork, and

accountability our teams bring to serving clients and communities every day. We value these

honors because they affirm a culture that enables us to attract, develop, and retain exceptional

talent. As a result, Seacoast has built an industry-leading commercial banking and wealth

management team that shares a disciplined, relationship-based philosophy and deep local market

expertise. Their impact is evident in our results, driving industry-leading growth in loan

outstandings and assets under management while maintaining a steadfast focus on prudent risk

management and long-term value creation. We believe our culture is a true competitive advantage

and a critical enabler of sustainable long-term growth.

Scalable Technology and Preparing an AI-Ready Infrastructure to

Drive Operating Leverage

A critical enabler of Seacoast's long-term growth strategy is our continued investment in scalable,

enterprise-grade technology that strengthens back-office efficiency, enhances risk management,

and prepares the franchise for an increasingly AI-driven financial services landscape. Over the past

several years, we have modernized our core systems, data architecture, and operating platforms to

ensure they scale efficiently as the franchise grows. These investments are designed to drive

sustainable operating leverage by automating routine processes, improving data quality and

decision support, and enabling more consistent execution across the organization. Just as

importantly, they position Seacoast to responsibly adopt emerging AI-enabled tools over time,

enhancing productivity, insight, and customer experience while maintaining strong governance and

controls. We view technology not as a standalone initiative, but as a foundational capability that

supports scale benefits, ongoing operating leverage, and ultimately durable shareholder returns.

Entering Our 100<sup>th</sup> Year with Strength and Momentum

As we approach Seacoast's 100<sup>th</sup> anniversary in 2026, we do so from a position of strength. We

have built a stronger franchise with expanded market presence, improved funding advantages, and

meaningful capital flexibility. We have demonstrated the ability to execute complex integrations

while maintaining operating discipline and customer focus. And we remain committed to growing

relationships, investing in talent and capabilities, and delivering improved returns for shareholders.

Our optimism about the future is grounded in fundamentals: a relationship-based model that has

proven resilient; a balance sheet managed with discipline; a culture that attracts and develops

exceptional teams; and a strategy that is clear and consistent. We do not measure success by a

single quarter or a single year. We measure it by building a franchise that compounds value over

time—delivering strong performance in favorable environments and remaining resilient when

conditions are less favorable.

On behalf of our Board of Directors and all of our associates, thank you for your continued

confidence in Seacoast. We are proud of what we accomplished in 2025, and we are energized by

the opportunity ahead as we enter our 100<sup>th</sup> year of serving our customers, communities, and

shareholders.

SEACOAST BANKING CORPORATION OF FLORIDA3 PROXY STATEMENT 2026

Compensation Philosophy

Our compensation philosophy is to align pay with performance and long-term shareholder interests, while supporting prudent risk-

taking and retention. The majority of named executive officer compensation is variable and tied to the achievement of financial,

strategic, and individual performance objectives. Our program balances short- and long-term incentives and incorporates both

quantitative and qualitative performance measures.

Pay for Performance Alignment

Seacoast's executive compensation program is designed to directly align pay outcomes with Company performance and long-term

shareholder value creation. A substantial portion of compensation for named executive officers is variable and at risk, with payouts

dependent on the achievement of pre-established financial, operational, and strategic objectives. For 2025, incentive compensation

outcomes reflected Seacoast's performance and management's execution of key strategic priorities.

Short-term incentive awards were tied primarily to one-year measures of profitability, balance sheet discipline, loan and deposit

growth, and risk management. The Company's strong performance in 2025 included 9% organic loan growth, significant

improvements in profitability metrics, and the closing of two strategic acquisitions. As a result, shareholder returns outperformed

the peer group in 2025.

Long-term incentive awards for 2023-2025 were below target, reflecting relative performance over the three-year period, including

the impact of a strategic pullback in loan growth in 2023 and 2024 amid broader banking industry volatility. This resulted in lower

than targeted achievement of the LTI awards based on the full three-year performance relative to peers.

For additional context on compensation decisions and the relationship between performance and pay outcomes, see the "Letter

from the Compensation and Governance Committee Chair" in the "Compensation Discussion and Analysis" section.

Shareholder Engagement and Board Responsiveness

We approach shareholder engagement as an integrated, year-round process by way of various channels to engage with shareholders

and analysts, including face-to-face and virtual meetings, conferences, road shows, investor calls, quarterly earnings calls and

annual shareholder meetings, as well as distributing regular communications through our annual report and proxy statement. Our

Board and senior management value our shareholders' perspectives and feedback.

For additional detail about our shareholder outreach and responsive actions, see the "Letter from our Compensation and

Governance Committee Chair" and "Shareholder Outreach" in the "Compensation Discussion and Analysis" section.

Communications with the Board

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.

Series A Non-Voting Preferred Stock

On October 1, 2025, in connection with the acquisition of Villages Bancorporation, Inc., the Company issued 11,250 shares of Series

A Non-Voting Preferred Stock (the "Series A Preferred Stock"). Each one-thousandth (1/1,000th) of a share of Series A Preferred

Stock is convertible into one share of Seacoast Banking Corporation of Florida common stock, subject to certain restrictions set

forth in the Company's Articles of Incorporation and applicable law. The acquisition of Villages Bancorporation, Inc. was very well

received with a strong stock reaction and meaningful appreciation in the valuation of the Company as a result of the transaction. We

expect the transaction to be approximately 22% accretive to earnings in 2026, with a modest earnback period on tangible book

value per share.

Holders of Series A Preferred Stock are entitled to receive dividends on a ratable basis with holders of common stock when, as and if

dividends are declared by the Company's Board of Directors and are payable on the Common Stock.

The Series A Preferred Stock does not carry voting rights. As such, it does not create unequal or superior voting rights and is

non-voting except where class voting is legally required, and only with respect to items that affect the rights of the holders as a

class.

SEACOAST BANKING CORPORATION OF FLORIDA5 PROXY STATEMENT 2026

Director Nomination Process

The Compensation and Governance Committee ("CGC") serves as the Company's nominating committee. The CGC annually reviews

and makes recommendations to the full Board of Directors regarding the composition and size of the Board of Directors and its

committees. The CGC recommends, from time to time, to the Board new candidates for appointment to the Board and for

nomination for election to the Board by the Company's shareholders in addition to annually recommending current director

nominees if determined to be in the best interest of the Company and its 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 CGC. Each member of

the CGC 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.

Given the evolving needs and business strategies of the Company, the CGC believes that the Board of Directors as a whole should

have diversity of thought and experience, which may 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 and enhance shareholder value. The Board and the CGC also understand the importance of Board refreshment and

composition, and strive to maintain an appropriate balance of tenure, skills and fresh perspectives on the Board. The Board believes

that new perspectives and new ideas are critical to a forward-looking and strategic board, as is the ability to benefit from the

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

---

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, as amended.

SEACOAST BANKING CORPORATION OF FLORIDA6 PROXY STATEMENT 2026

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 2026 Annual Meeting,

no shareholder director nominee recommendations were received.

BOARD AND GOVERNANCE HIGHLIGHTS

Board Composition

Seacoast continues to build a 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 Corporate Governance

Guidelines require that a majority of the Board be composed of independent directors. Our Board consists of ten independent Board

members as of the Annual Meeting date, inclusive of our director nominees. 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.

To further strengthen our corporate governance, our independent directors annually select a Lead Independent Director who chairs

regularly scheduled executive sessions, without management present.

In accordance with the Corporate Governance 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.

We have refreshed our Board with new talent to increase the breadth of experience and to better align overall Board capability with

our strategic objectives. Since 2017 and as of the Annual Meeting date inclusive of our director nominees, we have added eight 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.

Although Seacoast does not have a mandatory Board retirement requirement, we actively use board evaluations and succession

planning and will continue to refresh the board over time.

Our Board is 79% independent with an average age of 65 years as of the Annual Meeting date, inclusive of our director nominees.

We have a well-balanced tenure with over half our Board with less than 10 years.

Corporate Governance at Seacoast

![](sbcf-20260410_g14.gif)

Our goal is to maintain a corporate governance framework that supports an engaged, independent board with varying 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

Our Board of Directors has ultimate oversight responsibility for strategy and risk management, and directly advises management on

development and execution of the Company's strategy. The Board 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.

Oversight is also provided through the extensive work of the Board's committees – Audit Committee; Compensation and Governance

Committee; Corporate Development Committee; Enterprise Risk Management Committee; and Information Technology Committee –

in key areas such as financial reporting, internal controls, compliance, corporate governance, compensation programs, capital

planning, risk management and cybersecurity. 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. 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. Additionally, our Information

Technology Committee focuses on the Company's risks and exposures related to information and data security, cybersecurity, data

privacy, disaster recovery and business continuity.

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, natural disasters, acts of war or terrorism or cybersecurity breaches; and

• business-specific risks related to financial reporting, credit, liquidity, 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 ERMC of the Board of Directors regularly evaluates our overall risk profile and oversees our risk management programs, which

are implemented by our chief risk officer.

Governance Policies

Seacoast is committed to long-term success through strong corporate governance and ethical business practices, with appropriate

controls and transparency forming the foundation for achievement of our strategic mission.

Important elements of our corporate governance framework are our governance policies, which include:

• Corporate Governance Guidelines

• Compensation Recoupment Policy

• Insider Trading Policy

• Code of Conduct

• Code of Ethics for Financial Professionals

• Charters for each of our Board committees

You may view these and other corporate governance documents on our investor relations website located at

www.SeacoastBanking.com, or request a copy, without charge, upon written request to Seacoast Banking Corporation of Florida, c/o

Corporate Secretary, 815 Colorado Avenue, P. O. Box 9012, Stuart, Florida 34995. Information included on our website, other than

the proxy statement and form of proxy, is not a part of the proxy soliciting material and is not deemed incorporated herein.

Data Privacy and Information Security

The Company's information security program is designed to protect sensitive information from unauthorized access, use, disclosure,

alteration, or destruction, and to maintain the confidentiality, integrity, and availability of our information assets, including

employee and customer non-public information, financial data, and internal operational information. 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 ITC and ERMC of the Board of Directors on an annual basis. Through an integrated process,

key risks, including those related to privacy and cybersecurity are reviewed and evaluated by the ITC and ERMC before they are

reviewed by the full Board. We have also adopted a Digital Banking 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.

Over the past few years, the Board and the ERMC and ITC have spent significant time overseeing management's efforts to address

evolving and growing cyber- and technology-related risks and opportunities, including, most recently, the growth in the use and

implementation of generative artificial intelligence. 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 mandatory employee training, educational opportunities and regular associate communications

• Third party program oversight

• Encryption technologies

• Incident response program

We provide our associates with ongoing training opportunities in addition to annual mandatory training 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. Should an information security incident occur, we have resources to assist with forensic analysis, response

strategies and crisis communications.

Cybersecurity Risk Management and Governance

The Company's cybersecurity program, including our information security policies, is designed to align with regulatory guidance and

industry practices. To protect our information systems, network, and information assets from cybersecurity threats, we use various

security tools, products and processes that help identify, prevent, investigate, and remediate cybersecurity threats and security

incidents.

The oversight of cybersecurity, including potentially significant cybersecurity threats or incidents, is delegated primarily to the ITC

of the Board. The ERMC of the Board has primary responsibility for overseeing the Company's comprehensive ERM program. The

Enterprise Risk Management program assists senior management in identifying, assessing, monitoring, and managing risk, including

cybersecurity risk. Cybersecurity matters and assessments are regularly included in ITC and ERMC meetings. Additionally, the

Board assesses the risks and changes associated with cybersecurity threats through presentations and reports provided by our ITC

and ERMC, including participation in annual cybersecurity and information security education and training. For more information

about our Board's oversight of cybersecurity risk, please see "Cybersecurity - Cybersecurity Governance" in our Annual Report on

Form 10-K for the fiscal year ended December 31, 2025.

SEACOAST BANKING CORPORATION OF FLORIDA11 PROXY STATEMENT 2026

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. Our governance principles require that a substantial majority of our directors meet the criteria for

independence required by Nasdaq. The Board of Directors has determined that, in 2025, 70% of the Company's directors are

independent directors under the Nasdaq rules. The Company's independent directors in 2025 were: Dennis J. Arczynski, Jacqueline

L. Bradley, H. Gilbert Culbreth, Jr., Christopher E. Fogal, Maryann Goebel, Dennis S. Hudson, III, Robert J. Lipstein and Alvaro J.

Monserrat. On March 26, 2026, Michael E. Griffin, Kathleen B. Kay and Randolph A. Moore, III were appointed to the Board. The

Board has determined that Michael E. Griffin, Kathleen B. Kay and Randolph A. Moore are independent directors.

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 <br>Review and Investor <br>Feedback<br>| The CGC reviews corporate governance principles and makes recommendations annually, with consideration <br>given to generally accepted practices and feedback from investors. This committee also oversees the <br>process for annual board evaluations.<br>|
| Annual Board & <br>Committee Self-<br>Evaluations<br>| The Board and each Board committee conduct annual self-evaluations. In 2025, Board and committee <br>evaluations were individually conducted to assess the effectiveness of the Board and committees of the <br>Board.<br>|
| Summary and Review | For the 2025 Board and committee evaluations, responses and comments were compiled and summarized, <br>and were reviewed by the Chairman and Lead Independent Director, who together presented summary <br>results to the full Board. The committee evaluations were reviewed by the respective committee chairs, who <br>then discussed the results with their respective committees and the full Board.<br>|
| Actions | In response to feedback from the evaluation process, the Board and committees work with management to <br>take concrete steps to improve policies, processes and procedures to further Board and committee <br>effectiveness. As a result of the 2025 Board evaluation process, the Board gained insight as to governance <br>structure and committee rotation opportunities, director succession, and board refreshment. In early 2026, <br>the Board appointed three new directors to the Board.<br>|

---

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 Independent Director from the

independent directors. Our Board believes that the Lead Independent Director serves an important corporate governance function

by providing separate leadership for the non-management and independent directors. In January 2026, 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 three times in executive session in 2025.

![Artboard 1.gif](sbcf-20260410_g13.gif)

SEACOAST BANKING CORPORATION OF FLORIDA12 PROXY STATEMENT 2026

Committee Structure

Oversight is also provided through the extensive work of the Board's five committees – Audit, CGC, CDC, ERMC, and ITC – 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.

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 Board members are encouraged to make site visits, to meet

with management, and to attend Company, industry and other events.

Audit Committee Report

![](sbcf-20260410_g14.gif)

In 2025, the Audit Committee was 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, 2025 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

2025. 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, 2025. 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 discussed with Crowe

LLP, among other things, 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, 2025, for filing with the Securities and Exchange Commission.

SEACOAST BANKING CORPORATION OF FLORIDA18 PROXY STATEMENT 2026

A Letter From Our Compensation and Governance

Committee Chair

![](sbcf-20260410_g14.gif)

Dear Fellow Shareholders,

On behalf of the Compensation and Governance Committee (the "Committee") and the Board of Directors of Seacoast

Banking Corporation of Florida, I am pleased to present our Compensation Discussion & Analysis. This section of our

Proxy Statement explains how our executive compensation program is designed to align pay outcomes with Company

performance and long-term shareholder value creation.

2025 Performance and Shareholder Outcomes

2025 was a year of strong execution and substantial progress. Our management team successfully completed two

strategically important acquisitions that meaningfully increased the franchise value of the Company and were

accretive to the Company's profitability, all while delivering industry-leading growth in loans and wealth division

assets under management. These actions contributed to adjusted net income of $169.5 million, or $1.84 per diluted

share, and strengthened the Company's earnings power and long-term positioning.

Importantly, shareholders benefited from these results. One-year total shareholder return significantly outperformed

both our peer group and the broader market, reflecting confidence in Seacoast's strategy, execution, and future

prospects as reflected in improved earnings expectations and top quartile valuation.

Pay-for-Performance Alignment

Our compensation philosophy is straightforward: executive pay should reflect performance, risk discipline, and

shareholder experience over time. The Committee believes 2025 compensation outcomes demonstrate this

alignment.

Given strong operational and financial results, the Company's 2025 Short-Term Incentive Plan paid above target,

resulting in payouts of 150% of target for our Named Executive Officers. This outcome was driven by strong earnings,

return on assets, and loan growth, as well as the disciplined and successful execution of the Heartland Bancshares,

Inc. and Villages Bancorporation, Inc. acquisitions. Throughout the year, management also maintained a strong risk

management culture, which remains a core expectation of performance.

At the same time, our long-term incentive outcomes reflect a balanced and objective assessment of performance

across economic cycles. Performance-based share awards for the 2023–2025 period, which were tied to Relative

Average Annual EPS Growth and Average Annual Return on Average Tangible Equity, were earned below target,

resulting in payouts at 57% of target. This outcome reflects relative performance over the full three-year period and

demonstrates that compensation is not insulated from longer-term shareholder returns. During 2023 and 2024,

management and the Committee made deliberate decisions to moderate growth and preserve capital amid

heightened credit and economic uncertainty. While these actions constrained near-term returns relative to some

peers, they positioned the Company to deploy capital into highly accretive opportunities. That capital discipline

enabled the successful execution of the Heartland and Villages acquisitions in 2025, which the Committee believes

materially enhanced long-term shareholder value.

Shareholder Engagement and Program Enhancements

At our May 2025 annual meeting, approximately 61% of votes cast supported our advisory Say-on-Pay proposal, a

decline from prior years. The Committee took this outcome seriously, and shareholders representing a significant

portion of our outstanding shares were directly engaged with to better understand their perspectives.

Through this outreach, shareholders emphasized the importance of clear pay-for-performance alignment, incentive

plan design, and transparent disclosure. In response, the Committee conducted a thorough review of the Company's

executive compensation programs and related disclosures, and made responsive enhancements.

![Artboard 1.gif](sbcf-20260410_g13.gif)

SEACOAST BANKING CORPORATION OF FLORIDA19 PROXY STATEMENT 2026

With guidance from our new independent compensation consultant, we expanded our explanation of how

performance goals are set and evaluated, disclosed threshold, target, and maximum levels for annual incentive

metrics and weightings, and enhanced transparency around our long-term incentive plan design, performance

metrics, payout scales, and results for completed cycles. We also enhanced disclosure regarding our compensation

governance practices, including clarifying the operation of our clawback policy. The Committee believes these

enhancements directly address shareholder feedback and reinforce our commitment to sound compensation

governance.

Looking Ahead

The Committee remains focused on maintaining a compensation program that supports Seacoast's strategy,

promotes prudent risk management, attracts and retains strong leadership, and aligns executive compensation

with sustainable performance and shareholder returns. We will continue to engage with shareholders and

thoughtfully consider their input as we evolve our compensation programs over time.

We appreciate our shareholders' engagement and thank you for your continued support of Seacoast.

COMPENSATION DISCUSSION AND ANALYSIS

![](sbcf-20260410_g14.gif)

Say on Pay Results

We have a long history of strong shareholder support for our Board's pay-for-performance philosophy, executive compensation

design and pay actions. From 2017 to 2024, support for our "Say on Pay" proposal averaged 97% of votes cast on the matter.

However, support for the proposal last year fell to 61%.

![1099511673440](sbcf-20260410_g37.gif)

Shareholder Outreach Summary

The CGC considered the level of shareholder support of our say-on-pay proposal at our 2025 annual meeting, which was

considerably lower than the strong support received in prior years. We invested time to better understand and address investor

perspectives and shareholder concerns and we expanded our shareholder outreach in 2025 and early 2026. Outreach efforts

included meetings with investors to discuss executive compensation, governance practices and performance alignment.

Following our 2025 annual meeting, we reached out to our top 20 shareholders, which represent the holders of over 60% of our

outstanding institutionally held common stock. As a result of our outreach in 2025 and early 2026, investors representing

approximately 20% of our outstanding common shares responded with a desire to express feedback. Engagements were generally

led by our chief financial officer, chief strategy officer and chief human resources officer, who actively participated in discussions to

seek input from shareholders on topics of interest. Insights from these meetings were shared directly with the Board.

In meetings held in 2025 and early 2026, we received valuable feedback in our conversations with shareholders focused on our

executive compensation program practices and corporate governance aspects. The CGC, and the Board as a whole, actively

evaluated the feedback and identified enhancements to our executive compensation disclosures, corporate governance practices

and board tenure. The Board took into consideration the concerns that were voiced during our engagements and we have made

improvements that address many of our shareholders' key concerns.

the actions we have taken in response.

strategic acquisitions that brought attractive funding with leading market share, and strengthened our ability to serve clients across

some of the most dynamic markets in Florida. Our acquisition of Villages Bancorporation, Inc. introduced a highly desirable presence

in a unique and rapidly growing market, and meaningfully enhanced our capacity for sustained growth. We also welcomed Heartland

Bancshares, Inc. into Seacoast and completed the system conversion during the year. Seacoast's relationship-driven model will

continue to support the longstanding history of community banking and deep local ties that made these two banks so exceptional.

On an organic basis, loans increased 9%, we improved operating leverage, with the adjusted efficiency ratio more than five points

better year over year, and expanded our footprint. In combination, those drivers translated into 45% growth in adjusted pre-tax,

pre-provision earnings, demonstrating meaningful momentum in the earnings engine of the Company. Our strong foundation

provides ample capacity to support future organic growth, attract and retain talent, invest in productivity, and act opportunistically

when we see compelling opportunities. Key accomplishments in 2025 include:

• Net income of $144.9 million, an increase of $23.9 million, or 20%, compared to 2024, and adjusted net income<sup>1</sup> of

$169.5 million, an increase of $37.0 million, or 28%, compared to 2024

• On an adjusted basis, pre-tax pre-provision earnings<sup>1</sup> of $274.7 million increased 45% from the prior year

• Net interest income grew $121.5 million, or 28%, to $553.5 million, and the net interest margin expanded 34 basis

points to 3.58%

• 9% organic loan growth, reflecting the value of investments made in recent years to attract talent and expand the

commercial banking team

• Assets under management in our wealth division expanded meaningfully in 2025, adding $549 million in new organic growth

• Stronger than peer loan-to-deposit ratio of 78%, well positioned for continued growth and value creation

• Continued strong capital position, with a Tier 1 capital ratio of 14.5%, and a tangible equity (including convertible

preferred stock) to tangible assets ratio of 9.31%. Tangible equity and assets exclude goodwill and other intangible

assets

• Through the transformative acquisitions of Villages Bancorporation, Inc. and Heartland Bancshares, Inc., accompanied by strong

organic growth, total assets grew 37% to $20.8 billion

• Net charge-offs to average loans of 0.12% in 2025 compared to 0.27% in 2024

• Nonperforming assets to total assets of 0.37% at December 31, 2025 compared to 0.65% at December 31, 2024

• Increased the quarterly dividend 5% to $0.19 per share

• Named by American Banker as a 2025 Best Places to Work

• Achieved an employee engagement score of 85%, as reported through our 2025 employee engagement survey

2025 Executive Compensation Actions

The CGC and CEO evaluate the performance of NEOs and other senior executives using a combination of quantitative and qualitative

measures. Given our accelerated growth, evolving business, and changing executive responsibilities, performance is assessed

through scorecards approved at the beginning of each year that establish performance expectations. Actual results are evaluated at

year-end, and performance ratings are developed for each NEO to inform compensation decisions. The CGC believes that qualitative

performance assessments support effective compensation, development, and long-term shareholder value creation.

The CEO works closely with the CGC in establishing executive compensation, including annual incentive opportunities. The CEO

evaluates the performance of each NEO and other senior executives and makes compensation and incentive recommendations to

the CGC based on these evaluations, market compensation data, and other relevant information. The CGC independently evaluates

the CEO's performance and determines his compensation without the CEO present. The CGC also meets with the independent

members of the board to review the CEO's performance and to discuss and approve the CEO's compensation.

Equity awards granted in 2025 were determined based on 2024 performance scorecard evaluations. Equity awards related to 2025

performance will be granted in 2026. Annual cash incentive awards for 2025 were based on 2025 performance evaluations and will

be paid in 2026.

Compensation Program and Philosophy

Our executive compensation program is designed to attract, motivate, and retain experienced executives while aligning pay with

performance and shareholder interests. The CGC seeks to balance short-term results with long-term value creation. Our long-term

business strategies and key priorities guide our compensation programs, which are designed to accomplish the following:

• Allow the Company to compete for, hire and retain talented executives critical to our success, with the capabilities required

to achieve our business objectives related to growth, innovation and profitability

• Incentivize executives to deliver sustainable results with a risk appropriate framework

• Establish clear expectations for individual goals that recognize and reward individual achievement and contributions

consistent with our enterprise-wide growth, return and risk management objectives

• Use performance-based compensation to link the success of the individual with the success of the Company

• Hold executives accountable and reward long-term performance

• Align executive compensation with the interests of our shareholders

Elements of Compensation

The CGC is committed to aligning our compensation programs with the Company's evolving business strategy, sound governance

principles, effective risk management practices, and our objective of generating superior long-term returns for shareholders. To

support this objective, we emphasize pay-for-performance in the design and administration of our executive compensation

programs. We believe that our executive compensation framework effectively aligns the compensation of our CEO and other

executive officers with long-term shareholder interests. In making compensation decisions and designing program structure, the

CGC considers competitive market practices, including data from a carefully selected compensation peer group. The following table

summarizes the primary elements of our executive compensation program.

2025 NEO Mix of Target Total Direct Compensation

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 short-term incentive opportunities

and the target value 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 target Total Direct Compensation ("TDC"). The following charts

illustrates the relative emphasis of each pay element in relation to the target TDC.

Elements of Compensation Decision Making

Role of 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 selection of our peer group, issuance of equity awards, and

certification of results;

• evaluates the performance of the CEO and determines the CEO's compensation for recommendation to the Board;

• 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 of Chairman and CEO

The CEO conducts a quantitative and qualitative assessment of NEO performance based on pre-established annual goals. At the

beginning of each year, the CGC approves performance scorecards that align with the Company's strategic and operating priorities

and establish the performance criteria by which results are evaluated at year-end. Following the completion of the fiscal year, the

CEO evaluates NEO performance against these scorecards and develops performance ratings, which are presented to the CGC for

review and discussion.

Our CEO works closely with the CGC in establishing executive compensation for each NEO and other senior executives. Based on his

performance evaluations, competitive market data, and other relevant considerations, the CEO provides recommendations to the

CGC regarding base salary adjustments, annual incentive payouts, and long-term incentive awards for the NEOs and other senior

executives. The CEO also provides incentive compensation target payment recommendations for the Committee's consideration.

Role and Independence of the Compensation Consultant

The CGC strives to adhere to effective governance practices and principles. As such, our CGC is comprised solely of independent

directors and is advised by external independent compensation consultants on compensation matters. The Committee retained

Alvarez and Marsal, LLC ("A&M") as its independent compensation consultant to advise the CGC in 2024 and the first half of 2025.

A&M periodically attended CGC meetings, including executive sessions and provided information and advice independent of

management.

Following the 2025 annual meeting, the CGC engaged Meridian Compensation Partners ("Meridian") as its independent

compensation consultant to advise on the Company's executive compensation program and provide fresh perspective, insights and

expertise. Meridian regularly attended CGC meetings in the second half of 2025 and in 2026, including executive sessions, and

provided information and advice on areas of compensation philosophy, design and structure and market pay practices to assist with

compensation decisions. At the direction of the CGC Chair, Meridian also assisted management with various activities that support

Seacoast's executive compensation program.

The CGC evaluated independence considerations pursuant to SEC and NASDAQ rules and concluded that the engagements of A&M

and Meridian, and the services each provided, did not raise any conflict of interest.

SEACOAST BANKING CORPORATION OF FLORIDA28 PROXY STATEMENT 2026

Compensation Peer Group and Market Data

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 utilizes publicly disclosed information and data from a size-appropriate, high-

performing core bank industry compensation peer group in its decision process. As needed, we supplement information and data

from our compensation peer group with proprietary survey data from the McLagan's Regional Banking and Pearl Meyer's Mid-Size

Banking surveys.

The CGC does not target a specific percentile of market compensation when establishing base salaries, annual cash incentives, or

long-term equity awards for our NEOs. While market data serves as an important benchmark to support the CGC's deliberations,

compensation decisions are determined based on a range of factors, including Company performance, individual contributions,

leadership impact and talent considerations. The CGC reviews proposed pay actions relative to market data to assess overall

reasonableness, with the market benchmarks serving as a reference and validation tool rather than a formulaic determinant of pay

outcomes.

For 2025, the peer group was selected from publicly traded banks with asset sizes between $10-$40 billion with comparable

geographies, business models, risk profiles and principles as Seacoast. Seacoast's asset size was approximately $20.8 billion as of

December 31, 2025.

The CGC reviews the peer group annually to ensure its continued appropriateness and makes changes when necessary. In 2025, the

CGC replaced two peers, Home Bancshares, Inc. (HOMB) and First Financial Bankshares, Inc. (FFIN), with Prosperity Bancshares, Inc.

(PB) and OceanFirst Financial Corp. (OCFC) to better represent reasonable comparability based on asset size, geography, business

mix and risk profile. In light of continued industry merger and acquisition activity, the CGC expanded the peer group to include

three additional peers; FB Financial Corp. (FBK), First Merchants Corp. (FRME) and Fulton Financial Corp. (FULT), each of which fall

within the CGC's approved peer group parameters.

Our 2025 Peer Group was comprised of the following companies:

 **2022 PEER GROUP**

2025 Elements of Compensation and Pay Decisions

Base Salaries

Our NEOs receive a base salary that reflects the CGC's assessment of their skills and value to Seacoast. It is the CGC's philosophy to

provide competitive base salaries relative to comparable executives in the compensation peer group and make market-based

adjustments as it deems appropriate. Salaries can be adjusted to reflect experience and tenure in a position, internal pay equity,

promotions, changes in scope of responsibilities, individual performance, and retention considerations. Salary increases for the

NEOs, including our CEO, were 5% or less in 2025. The 2025 annualized base salary actions for our NEOs are summarized in the

following table.

Annual Short-Term Incentive

Seacoast annual short-term incentive ("STI") compensation is designed to incent our NEOs to achieve critical pre-established

annual financial and non-financial goals that drive our key strategic and operational results and help to enhance shareholder value.

The CGC is responsible for approving performance goals and related payout levels, setting each NEO's target award opportunity and

approving payouts under the STI plan. The CGC retains the authority to exercise informed discretion to reduce otherwise earned

incentive payouts as it deems appropriate.

Target Short-Term Incentive Opportunity

The CGC assigned each NEO a target annual incentive award opportunity for 2025 based on competitive market data and the

executive's position, responsibilities and role.

---

| | | |
|:---|:---|:---|
| Named Executive Officer | Base Salary | STI Target ($) |
| Charles M. Shaffer | $1000000 | $1000000 |
| Tracey L. Dexter | $486875 | $350000 |

| Juliette P. Kleffel | $575000 | $375000 |
| Austen D. Carroll | $525000 | $375000 |

Each NEO may earn between 0% and 200% of his or her target annual incentive opportunity based on achieved performance

against pre-set performance goals, with 50% of target earned for threshold performance, 100% of target earned for target

performance, and 200% of target earned for maximum performance. For performance between threshold and target, and target and

maximum, the payout is determined by linear interpolation. Any amounts earned for 2025 performance were paid in cash in 2026.

Short-Term Incentive Performance Metrics

For purposes of 2025 STI, the CGC selected the following quantitative performance measures.

---

| | | |
|:---|:---|:---|
| Performance Metric | Weight | Why it Matters |
| Adjusted Earnings Per Share (EPS) | 25% | Earnings per share (EPS) is the portion of the Company's profit allocated <br>to each share of common stock. The measure is broadly used as an <br>indicator of profitability, useful for tracking performance over time or in <br>comparison to benchmarks.<br>|
| Adjusted Return on Assets (ROA) | 25% | Net income as a percentage of average total assets. A broadly used <br>indicator of efficient use of assets to generate earnings, useful for <br>tracking performance over time or in comparison to benchmarks.<br>|
| Organic Loan Growth | 25% | Core revenue expansion of real sustainable demand for lending <br>activities and ongoing customer relationships that support profitability <br>and long-term franchise value.<br>|
| Organic Deposit Growth | 25% | Drives customer engagement and relationships for cross-product <br>revenue generating opportunities and supports strong liquidity <br>balances, reducing interest rate risk and extending long-term franchise <br>value.<br>|

---

Our performance goals were set with the objective of achieving strong financial results and factoring in prudent risk management.

The CGC believes these performance metrics capture the most important aspects of the Company's top and bottom-line

performance. The equal weighting among the performance metrics aligns with the relative importance of the metrics and the

strength of our business.

While we did not achieve our targeted deposit growth, the company specifically took action to lower deposit costs at the expense of

overall deposit growth, resulting in faster deposit cost reductions than peers, greater net interest income and stronger margin

expansion, positioning the Company for better performance in 2026. While this impacted STI payouts, it is expected to result in

better returns for shareholders in the long run.

Qualitative Performance Scorecard

For the purposes of the STI compensation, including the 2025 STI, the CGC evaluates Company performance on a holistic basis,

considering achievement against established strategic priorities and risk management objectives that support the Company's

financial goals. The Committee first reviews the incentive award payouts that would be earned by the NEOs based solely on the pre-

established quantitative performance measures. The CGC then assesses the leadership team's execution of strategic priorities set at

the beginning of the year and, based on this evaluation, can exercise informed discretion to modify the calculated incentive award as

appropriate in determining the final payout amount for each executive. Under the terms of the STI program, the Committee may

increase or decrease the calculated award by up to 15%.

Long-Term Incentives

The CGC believes that a significant portion of the NEOs' target compensation should be delivered in the form of equity-based

incentives that motivate our executives to drive and create the long-term performance of the Company. These awards are intended

to reward performance over a multi-year period, align the interest of our executives with those of our shareholders, instill an

ownership culture, support retention, and elevate our visibility and appeal as an employer of choice for highly skilled talent. Long-

term incentive ("LTI") awards are granted to our NEOs under the 2021 Incentive Plan.

To align NEO compensation with long-term shareholder interest, the CGC grants LTI awards in the form of PSUs and RSAs, whereby

75% is granted in PSUs, with achievement levels dependent upon the Company's performance relative to the peer group, and 25% is

granted in time-based RSAs vesting over a 3-year period. We believe this emphasis on performance-based awards appropriately

aligns with shareholder interests.

The following summarizes the type, mix, vesting and performance objectives of equity granted to NEOs in 2025.

SEACOAST BANKING CORPORATION OF FLORIDA34 PROXY STATEMENT 2026

Performance Stock Unit ("PSU") Awards

PSU awards are granted as 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 average annual growth in EPS relative to the peer

group described under "Compensation Peer Group" ("EPS PSUs"). The remaining one-half of the PSUs will be earned based on

Seacoast's three-year average annual return on average tangible equity relative to the peer group ("ROATE PSUs"). PSUs that

achieved the applicable performance goals will vest following a one-year post-performance holding period and subject to the

grantee's continued service. The CGC selected EPS and ROATE given their importance in the Company's strategic plan and

significant influence on 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 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. 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.

| Relative Average Annual <br>Return on Average Tangible <br>Equity ("ROATE")<br>| Measures net income as a percentage of average <br>tangible equity annually over the performance <br>period, excluding goodwill and other intangible <br>assets.<br>| Evaluates the effectiveness with which <br>management deploys shareholders' tangible <br>capital, promoting disciplined capital allocation <br>and long-term returns on equity.<br>|

---

The number of ROATE Units and EPS Growth Units that shall become eligible to vest shall be determined as a percentage of the

target number of units granted, subject to the absolute performance limiters and caps and the performance gateway requirement

described below:

---

| | | |
|:---|:---|:---|
| Company's Ranked Percentile <br>Performance Against Peer Group<br>| Performance Level | Percentage of Granted Units <br>Eligible to Vest<br>|
| 90th Percentile or Above | Maximum | 225% |
| 50th Percentile | Target | 100% |
| 25th Percentile | Threshold | 25% |
| Below 25th Percentile | Below Threshold | 0% |

---

Vesting for ranked percentile performance that falls between the 25th and 50th percentiles and between the 50th and 90th

percentiles shall be determined to the nearest tenth of a percentage point by linear interpolation. Notwithstanding the Company's

ranked percentile performance described above:

• Vesting of the ROATE Units shall not exceed 100% of Target if the Company's average Annual ROATE for the performance

period is less than 5%;

• Vesting of the EPS Growth Units cannot exceed 100% of Target if the Company's average Annual EPS Growth for the

performance period is less than 0%; and

• No ROATE Units or EPS Growth Units shall vest if Tier 1 Capital Condition is not met as of the end of the last year of the

performance period.

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 2025 were issued in

recognition of 2024 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.

Risk Management

The CGC shares 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 reflects our commitment to listen to our shareholders and continuously refine our programs to align with

our governance and risk management efforts, particularly given the growth of Seacoast and changes within the industry and what is

deemed as best practice.

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 2025, 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.

Other Elements of the 2025 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 "2025 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", or "EDCP").

We offer these plans 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 Tables–Executive Deferred

Compensation Plan."

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 part-time and 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 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 "2025 Summary Compensation Table," the "2025 Components of All Other Compensation," and

the "2025 Nonqualified Deferred Compensation Table," and are described in the footnotes thereto.

SEACOAST BANKING CORPORATION OF FLORIDA37 PROXY STATEMENT 2026

Supplemental Executive Retirement Plan 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 "2025 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 do provide some of our NEOs

with modest perquisites such as a car allowance. We do not provide tax reimbursements, or "gross-ups," on perquisites. For

additional details regarding the executive perquisites, see the "2025 Summary Compensation Table" and the "2025 Components of

All Other Compensation."

Clawback Policy

Incentive-based compensation paid to executive officers is subject to recoupment under the Company's Compensation Recoupment

Policy. Under this policy, the Company is required to recoup incentive compensation paid to an executive officer or former

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.

In the event that the Company is required to prepare an accounting restatement, the Company will recover the amount of all

erroneously awarded compensation received by our executive officers during the three completed fiscal years immediately

preceding the date that the Company is required to prepare the accounting restatement and any transition period that results from

a change in the Company's fiscal year, within or immediately following those three completed fiscal years.

This Compensation Recoupment Policy complements a broader clawback policy, covering employees and compensation and

allowing the Company to recoup incentive compensation that was paid in reliance on materially inaccurate financial statements or

other materially inaccurate performance metric criteria.

The Compensation Recoupment Policy is available on our website at www.SeacoastBanking.com and is compliant with 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 | Holding Requirement |
| Individual/Group | Stock Ownership Target | Before Ownership <br>Target Met<br>| After Ownership <br>Target Met<br>|
| Chief Executive Officer | 5 times annual base salary | 75% of net shares <br>until target number of <br>shares is met | 50% of net shares <br>held for one year <br>after vesting/ <br>exercise |
| Other Senior Executive Officers | 3 times annual base salary | 75% of net shares <br>until target number of <br>shares is met | 50% of net shares <br>held for one year <br>after vesting/ <br>exercise |
| Non-Employee Directors | 5 times annual cash retainer | 100% of net shares <br>until target number of <br>shares is met<br>| 50% of net shares <br>held for one year <br>after vesting/ <br>exercise |

---

Our executive compensation program is designed to allow a participant to earn targeted ownership over a reasonable period, usually

within four years for executive officers and five years for non-employee directors, 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.

Supplemental Executive Retirement Plan ("SERP")

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

Company 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.

<sup>(1)</sup> The number of years credited service began on the date of the SERP Agreement dated December 10, 2021.

<sup>(2)</sup> The present value of accumulated benefit represents the current liability included in the Company's accounting records for Mr. Shaffer under his SERP Agreement. The

Company accounts for the SERP in accordance with ASC-710-10 Accounting for Post-Retirement Benefits Other Than Pensions. The present value was calculated using

a discount rate of 5.13% and assuming Mr. Shaffer will be paid the normal retirement benefit for twenty years in equal monthly installments beginning the month

following normal retirement age.

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. Amounts deferred prior to January

1, 2022 will be distributed following the participant's separation from service. For amounts deferred after January 1, 2022,

participants can elect to receive distributions of their deferred amounts upon a separation from service, a specified date, death,

disability, or a change in control.

A participant's elective deferrals to the EDCP are immediately vested.

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, quarterly or annual installments over a period not to exceed eleven years (monthly installments over a period not to

exceed five years for amounts deferred prior to 2022); or

• a combination of an initial lump sum of a specified dollar amount and the remainder in installments.

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 or her designated

beneficiary or to his or her estate.

2025 Nonqualified Deferred Compensation

The following table discloses, for each of the NEOs, contributions, earnings and balances during 2025 under the EDCP, described

SEACOAST BANKING CORPORATION OF FLORIDA43 PROXY STATEMENT 2026

Employment and Change in Control Agreements

The Company and the Bank currently maintain employment and change in control agreements with certain executive officers of the

Company, the terms of which are described in more detail below.

Employment Agreement with CEO Shaffer

On December 31, 2020, the Company and the Bank entered into an employment agreement with Mr. Shaffer. The employment

agreement replaced the previous change of control agreement between these parties dated September 21, 2016. Under the

agreement terms, Mr. Shaffer serves as the Company's President and Chief Executive Officer and a member of the Board of

Directors for Seacoast and the Bank effective January 1, 2021. The agreement extends Mr. Shaffer's employment under the

agreement terms for a term of three years and continuing until December 31, 2023, and provides for automatic one year extensions

unless expressly not renewed.

Under the agreement, Mr. Shaffer receives a base salary, medical, long-term disability and life insurance in accordance with the

Bank's insurance plans for senior management, as well as a car allowance and any other perquisites that are approved by the Board.

Mr. Shaffer may also receive other compensation including bonuses, and he will be entitled to participate in all current and future

employee benefit plans and arrangements in which senior management of the Bank may participate. In addition, the agreement

contains certain non-competition, non-disclosure and non-solicitation covenants.

Under the agreement, if Mr. Shaffer is terminated for "cause", or resigns without "good reason," as defined in the agreement, he will

receive payment of his base salary and unused vacation through the date of termination, and any unreimbursed expenses

(collectively, the "Accrued Obligations"). The employment agreement also contains provisions for termination upon Mr. Shaffer's

death or permanent disability.

If Mr. Shaffer resigns for "good reason" or is terminated "without cause" prior to a change in control, he will receive: 1) the Accrued

Obligations; and 2) upon execution of a release of all claims against the Company, severance of: a) two times the sum of his base

salary in effect on the date of separation, and the highest bonus earned by Mr. Shaffer for the previous three full fiscal years ("Cash

Bonus") payable over a period of 24 months, and b) continuing group medical, dental, vision and prescription drug plan benefits

("Continuing Benefits") for two years. If Mr. Shaffer resigns for "good reason" or is terminated "without cause", within twelve

months following a change in control (as defined in the agreement), he will receive: 1) the Accumulated Obligations; and 2) upon

execution of a release of all claims against the Company, severance of: a) three times the sum of his base salary in effect on the

date of separation, and the Cash Bonus payable in a lump sum, and b) Continuing Benefits for 36 months.

In addition, under the agreement, Mr. Shaffer is subject to the Company's policies applicable to executives generally, including its

clawback policy. For a further discussion of the payments and benefits to which Mr. Shaffer would be entitled upon termination of

Change in Control Agreements with Other Named Executive Officers

The Company entered into change in control employment agreements with Mr. Forlenza on March 30, 2017, and Ms. Dexter on

January 20, 2021 (each referred to as the "Executive" or by name).

Each agreement has an initial term of one year and provides for automatic one-year extensions unless expressly not renewed. A

change in control, as defined in the agreement, must occur during the term in order to trigger the agreement. The agreement

provides that, once a change in control has occurred, the Company agrees to continue the employment of the Executive subject to

the contract for a one-year period, in a comparable position as the Executive held in the 120-day period prior to the change in

control, and with the same annual base pay and target bonus opportunity. If the Executive is terminated "without cause" or resigns

for "good reason," as defined in the agreement, during the one-year period following a change in control, the Executive will receive:

• cash severance equal to the sum of (i) Executive's Annual Base Salary at the rate in effect on the date of termination, and (ii)

the Executive's average annual performance bonus for the last three full fiscal years prior to the date of termination

("Executive's Average Annual Performance Bonus")

• a prorated final year bonus, based on the Executive's Average Annual Performance Bonus; and

• health and other welfare benefits, as defined in the agreement, for a period of 12 months following termination.

The Executive is required to execute a release of claims as a condition to receipt of severance under the Change in Control

Agreement and is subject to protective covenants prohibiting the disclosure and use of the Company's confidential information and,

during the one-year period following a termination by the company for any reason other than for death or disability, or by the

Executive for Good Reason, protective covenants regarding non-competition, non-solicitation of protected customers; non-

solicitation of employees, and non-disparagement of the Company or its directors, officers, employees or affiliates.

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 year ending December 31, 2025, the median annual

total compensation of our employees (other than Mr. Shaffer, our CEO in 2025) was $73,673 and the annual total compensation for

Mr. Shaffer, as reported in the Summary Compensation Table was $4,481,361. Based on this information, for 2025, the ratio of

compensation for our Chief Executive Officer to the median employee was 61:1. 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 2023 based on our workforce as of December 31, 2023, and utilized the same associate

for 2024 and 2025 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.

The median employee's annual total compensation for 2025 was calculated 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.

<sup>(3)</sup> Fair value or change in fair value, as applicable, of equity awards in the "Compensation Actually Paid" columns was determined by reference to (1) for stock options, the

fair value calculated using the Black-Scholes option pricing model as of the applicable year-end or vesting date(s), determined based on the same methodology as used

to determine grant date fair values but using the closing stock price on the applicable revaluation date as the current market price and the volatility, dividend rates and

risk free interest rates determined as of the revaluation date, (2) for RSA awards, the closing price on applicable year-end dates or, in the case of vesting dates, the

actual vesting price, and (3) for PSU awards, the same valuation methodology as RSA awards above except year-end and vesting date values are multiplied by the

probability of target achievement as of each such date. The estimated probability of achievement of the 2020 PSUs was 100% at FYE 2020, FYE 2021, FYE 2022 and

96% at vesting in 2023. The estimated probability of achievement of the 2021 PSUs was 100% at FYE 2021 and FYE 2022, 125% at FYE 2023 and 102% at vesting in

2024. The estimated probability of achievement of the 2022 PSUs was 100% at FYE 2022, FYE 2023 and FYE 2024 and 78% at vesting in 2025. The estimated

2025 Performance Measures

For 2025, the CGC identified the performance measures listed below as the most important measures used to link "compensation

actually paid" to the NEOs to company performance:

• Net Income;

• Adjusted EPS<sup>1</sup> Growth; and

• Adjusted ROATE<sup>1</sup>

Visual Representation of the Information Provided in the Pay Versus Performance Table

The following graphs illustrate the comparison from 2021-2025 between our PEOs CAP and the average non-PEO NEO's CAP

amounts and Seacoast's TSR, the Peer Group's TSR, Net Income, Adjusted EPS Growth<sup>1</sup>, and Adjusted ROATE<sup>1</sup>. Changes in CAP

from year to year are impacted by numerous factors, including stock price volatility, outstanding award vesting, job performance,

increase in duties and responsibilities of our PEO and non-PEO NEOs and the amount of progress made towards company goals.

PROPOSAL 1

ELECTION OF DIRECTORS

![](sbcf-20260410_g14.gif)

General

Our 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 talent in the boardroom should generate exceptional levels of customer

service, financial performance and, ultimately, long-term shareholder returns compared to alternative investments. To this end, the

Board is committed to identifying directors to make meaningful contributions to our business and fully execute their duties and

responsibilities on behalf of our shareholders. The profile of our Board continues to evolve in response to the needs of our 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 the skills and qualifications of our directors, see "Skills and Qualification Mix."

In accordance with our bylaws and as set forth in our Amended and Restated Articles of Incorporation ("Articles of Incorporation"),

in no event will the Board have fewer than three directors or more than 14 directors. As of the date of this proxy statement,

Seacoast's Board of Directors consists of 14 members divided into three classes, serving staggered three-year terms, as provided in

our Articles of Incorporation. If the Amendment to the Articles of Incorporation, as described in Proposal 2, is approved by our

shareholders at the annual meeting, the three classes will phase out and all directors will stand for annual election by shareholders

by the 2028 annual meeting.

On March 26, 2026, Michael E. Griffin, Kathy Kay and Randolph A. Moore, III were appointed to the Board of Directors. At this time,

Seacoast's Compensation and Governance Committee ("CGC") and Board of Directors believe that 14 directors provide the

necessary diversity of background, experience and expertise and requisite independent oversight.

The Annual Meeting is being held to, among other things, re-elect Class III directors Dennis S. Hudson, III and Alvaro J. Monserrat

and the additional Class III directors Michael E. Griffin, Kathleen B. Kay and Randolph A. Moore, each of whom has been nominated

by the CGC of the Board of Directors. Each of the nominees is currently a director of Seacoast and each has been nominated by the

CGC. 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 and Thomas E. Rossin,

who are currently directors of the Bank only. If the Amendment to the Articles of Incorporation is approved by shareholders at the

Annual Meeting, each Class III director nominee will serve a one year term expiring in 2027. If the Amendment to the Articles of

Incorporation is not approved at the Annual Meeting, each Class III director nominee will serve a three year term expiring at the

2029 Annual Meeting and until their successors have been elected and qualified. Currently, the Board of Directors is classified as

follows:

---

| | | |
|:---|:---|:---|
| Class | Term | Name of Directors |
| Class I | Term Expires at the 2027 Annual Meeting | Jacqueline L. Bradley <br>H. Gilbert Culbreth, Jr.<br>Christopher E. Fogal<br>Charles M. Shaffer<br>Joseph B. Shearouse, III<br>|
| Class II | Term Expires at the 2028 Annual Meeting | Dennis J. Arczynski<br>Eduardo J. Arriola<br>Maryann Goebel<br>Robert J. Lipstein<br>|
| Class III | Term Expires at the 2026 Annual Meeting | Michael E. Griffin<br>Dennis S. Hudson, III<br>Kathleen B. Kay<br>Alvaro J. Monserrat<br>Randolph A. Moore, III<br>|

SEACOAST BANKING CORPORATION OF FLORIDA51 PROXY STATEMENT 2026

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 five nominees for election as

Class III directors. Please note that banks and brokers that do not receive voting instructions are unable 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 (five 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.

Nominees for Election at the Annual Meeting

In making the determination to select the five nominees for election at the Annual Meeting, the following qualifications were

considered by the Board.

**The five nominees listed have been nominated by Seacoast's Compensation and Governance Committee,** 

**and the Board of Directors unanimously recommends a vote "<u>FOR</u>" the election of all five nominees.**

SEACOAST BANKING CORPORATION OF FLORIDA59 PROXY STATEMENT 2026

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 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, which is the same peer group we use in determining executive

pay, see "Compensation Discussion and Analysis - 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

Non-employee directors are each paid a cash retainer for service on the board, plus an additional amount for serving as a chair of a

board committee or as the lead director. The annual cash retainers paid in 2025 remained unchanged from the prior year. 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

prorated for directors who join or leave the Board or have a change in Board roles during a quarterly period.

In addition, non-employee directors receive an annual grant of common stock, which is issued following the annual meeting of

shareholders. The annual stock award issued to non-employee directors following election or re-election at the 2025 annual

meeting of shareholders has a grant date value of $62,500 and was unchanged from the prior year.

In 2025, committee members received annual cash retainers for committee service to appropriately compensate them for the scope

of responsibilities and workload for serving on committees

The following table summarizes our annual non-employee director compensation program for 2025.

|:---|:---|
| Annual Retainer paid to all Non-employee Directors of the Company in 2025 <sup>(1)</sup> | Annual Retainer paid to all Non-employee Directors of the Company in 2025 <sup>(1)</sup> |

<sup>(1)</sup> Non-employee directors who serve on the Bank's Directors Credit Risk Committee and Trust and Wealth Committee will also receive a retainer of $5,000 for each such

committee.

<sup>(2)</sup> A number of directors have elected to receive all or a portion of their cash retainer in stock or stock options as described in the "2025 Director Compensation Table."

<sup>(3)</sup> Granted under the Amended 2021 Incentive Plan following election or re-election at each annual meeting of shareholders. Includes the grant of $62,500 of Company

common stock after the 2025 annual meeting of shareholders.

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.

The non-employee director compensation program approved by the Board for 2026 remains unchanged from 2025, except that

following the annual shareholder meeting in 2026, the annual stock award will increase from $62,500 to $70,000.

Lead Independent Director Compensation

The Board appointed Christopher E. Fogal as Lead Independent Director in December 2018 and in each subsequent year since then.

In 2025, Mr. Fogal received an additional annual cash retainer of $35,000 for his service as Lead Independent Director.

SEACOAST BANKING CORPORATION OF FLORIDA60 PROXY STATEMENT 2026

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 five times their base annual cash retainer within five years of joining the Board. Each director must retain

100% 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, other than Michael E.

Griffin, Kathleen B. Kay and Randolph A. Moore, III, who were appointed to the Board in March 2026.

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 2025.

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, 2025.

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 or at such other times as described below. 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.

Amounts deferred prior to January 1, 2022 will be distributed following the participant's separation from service. For amounts

deferred after January 1, 2022, participants can elect to receive distributions of their deferred amounts upon a separation from

service, a specified date, death, disability, or a change in control.

Upon a payout event, 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, quarterly or annual installments over a period not

to exceed eleven years (monthly installments over a period not to exceed five years for amounts deferred prior to 2022); or (iii) a

combination of an initial lump sum of a specified dollar amount and the remainder in installments. 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.

SEACOAST BANKING CORPORATION OF FLORIDA62 PROXY STATEMENT 2026

PROPOSAL 2

APPROVAL OF AMENDMENT TO THE AMENDED AND RESTATED ARTICLES

OF INCORPORATION OF SEACOAST BANKING CORPORATION OF FLORIDA

TO DECLASSIFY THE BOARD

![](sbcf-20260410_g14.gif)

General

Section 6.02 of the Company's amended and restated articles of incorporation currently divides the Board of Directors into three

classes. Each class is elected for a three-year term, with the terms staggered so that approximately one-third of directors, plus any

newly appointed directors, stand for election each year. Presently, the Class III directors' term expires at this 2026 Annual Meeting,

the Class I directors' term expires at the 2027 annual meeting, and the Class II directors' term expires at the 2028 annual meeting.

In the past, the Company's various Boards of Directors have believed that a classified board structure served the best interests of

the Company and its shareholders. Among other considerations, classified boards generally can provide for company and board

continuity and stability, promote director independence that is less subject to management or outside influence, and inhibit coercive

takeover tactics and special interest groups focused on short-term gain from taking rapid control of a company without giving its

board the opportunity to negotiate the payment of an appropriate premium.

While the Board continues to believe these are important considerations, the Board also understands that the corporate governance

best practices in recent years have moved away from classified boards in favor of electing all directors annually. As part of its

ongoing responsibilities to monitor current developments in corporate governance and review and recommend changes to the

Company's governing documents, the CGC evaluated the classified board structure during early 2026 and considered, among other

things, that an annual election of all directors would provide shareholders with greater opportunity to register their views at each

annual meeting on the performance of the entire Board over the prior year. Director elections are the primary means for

shareholders to express their views on the performance of individual directors, and a classified board structure affords shareholders

this opportunity only once every three years for each director.

After carefully weighing these considerations, the Board concluded that the annual election of all directors will both enhance our

corporate governance practices and be an effective way to maintain and enhance the accountability of the Board. Accordingly, the

Board, upon the recommendation of the CGC, unanimously determined that it is in the best interests of the Company to eliminate

the classified board structure.

The Proposal

Our Board of Directors is proposing the adoption of an amendment to the Company's amended and restated articles of incorporation

to declassify the Board such that each director will hold a one-year term.

On March 26, 2026, our Board of Directors adopted, subject to shareholder approval at the Annual Meeting, an amendment to our

amended and restated articles of incorporation to declassify the Board ("Amendment").

If Proposal 2 is approved, the elimination of the classified structure of the board will be phased in beginning with the 2026 Annual

Meeting, but no director's term in office will be shortened. Instead, the annual election of directors will be phased in over three

years, and all directors will stand for an annual election by 2028. Directors whose terms expire at the 2026 Annual Meeting and who

are standing for election at such meeting will be elected for a one-year term. At the 2027 annual meeting of shareholders, these

directors and those directors whose terms expire at such annual meeting and who are standing for election at such meeting (as well

as any other nominee for election as a director at such meeting) will be elected for a one-year term. Finally, at the 2028 annual

meeting of shareholders, all of our director nominees will stand for election for a one-year term. Accordingly, the board will be fully

declassified (with all board members standing for annual election) commencing with the 2028 annual meeting of shareholders.

If the Amendment is not approved by shareholders at this annual meeting, Class III directors will continue to serve a three-year term

upon approval by shareholders at the annual meeting.

The Amendment will not change the present number of directors or the board's authority to change that number or to fill any

vacancies or newly created directorships. If a vacancy occurs prior to the board being fully declassified, the new board member will

be appointed to fill the remaining portion of the term of the individual who has departed the board.

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 amended and restated articles of incorporation are being proposed at the Annual

Meeting. If 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.

This Proposal 2 requires the affirmative vote of two-thirds (66 2/3%) of votes cast at the Annual Meeting.

**The Board of Directors unanimously recommends a vote "FOR" Proposal 2.**

PROPOSAL 3

ADVISORY (NON-BINDING) VOTE ON COMPENSATION OF NAMED

EXECUTIVE OFFICERS

![](sbcf-20260410_g14.gif)

In accordance with the Exchange Act, we are required to include in this proxy statement and present at the Annual Meeting a non-

binding advisory 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 2026 Annual Meeting.

The Company believes that its executive compensation programs effectively align the interests of its named executive officers with

those of its shareholders by creating a combination of incentive compensation arrangements, in both cash and equity-based

programs, which are directly tied to performance and creation of shareholder value. A substantial portion of total direct

compensation for named executive officers is variable and at risk, with payouts dependent on the achievement of pre-established

financial, operational, and strategic objectives.

At the Company's 2025 annual meeting, the Company received the affirmative support of 61% of votes cast in favor of its say-on-

pay proposal, which was significantly lower than in prior years. In response to the shareholder vote, the Company expanded its

shareholder outreach in 2025 and early 2026 to better understand and address investor perspectives. In addition, the CGC

conducted a thorough review of the Company's executive compensation programs and related disclosures and, with guidance from

its independent compensation consultant, made responsive enhancements. The CGC believes these enhancements directly address

shareholder feedback and reinforce our commitment to sound compensation governance. For more information, see the "Letter

from our Compensation and Governance Committee Chair" and "Say on Pay Results" and "Shareholder Outreach Summary" in the

"Compensation Discussion and Analysis" section of this proxy statement.

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

CGC or the Board of Directors or creating or implying any additional fiduciary duty on the CGC or the Board of Directors, nor will it

affect any compensation paid or awarded to any executive. However, the CGC and the Board of Directors value our shareholders'

opinions, and, as in prior years, the CGC and the Board intend to evaluate the results of the 2026 say-on-pay vote when making

future decisions regarding compensation of the named executive officers. The Company encourages shareholders to carefully

review the "Compensation Discussion and Analysis" for a detailed discussion of the Company's executive compensation programs

and practices.

Currently, say-on-pay votes are held by the Company annually, and the next shareholder advisory vote will occur at the 2027 annual

meeting of shareholders.

This Proposal 3 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 3.**

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, 2026. 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 "<u>FOR</u>" Proposal 4.**

Relationship with Independent Registered Public Accounting Firm

Crowe LLP's report on Seacoast's consolidated financial statements for the fiscal year ended December 31, 2025 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.

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 $50,000 when aggregated with all similar transactions;

• 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; and

• any charitable contribution, grant or endowment by the Company to a charitable organization, foundation or university at

which a Related Party serves as a director, trustee or executive officer if the aggregate amount involved does not exceed the

greater of $200,000, or 5 percent of the charitable organization's total gross annual receipts.

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 Chevrolet automobile dealership. In 2025, Seacoast paid Gilbert

Chevrolet $111,307 for the purchase of two vehicles. The Audit Committee approved this arrangement.

• Director Randolph A. Moore, III is a former senior partner at Alston & Bird, LLP, that has served as legal advisor to Seacoast on

numerous matters, including M&A and securities transactions, SEC filings, corporate governance items, bank regulatory

matters and litigation. Mr. Moore received indirect compensation from Seacoast in 2025 as a result of the law firm's

representation. In 2025, Seacoast paid Alston & Bird, LLP approximately $2,735,332 for legal services, including as counsel

on M&A transactions and related activities.

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.

Shareholder Proposals for 2027

Shareholder Proposals for Inclusion in 2027 Proxy Statement

In accordance with Rule 14a-8 of the Securities Exchange Act of 1934, to be considered for inclusion in the Company's proxy

statement and proxy card for the 2027 Annual Meeting of Shareholders, a shareholder proposal must be received at the Company's

principal executive offices no later than December 10, 2026, which is 120 calendar days before the one-year anniversary of the date

on which the Company first mailed this proxy statement.

Shareholder Proposals for Presentation at 2027 Annual Meeting

If you do not wish to submit a proposal for inclusion in next year's proxy materials, but instead wish to present it directly at the 2027

Annual Meeting of Shareholders, you must give timely written notice of the proposal to the Company's Secretary pursuant to the

Company's advance notice provisions. To be timely, the notice (including a notice recommending a director candidate) must be

the date of the Annual Meeting. To be timely, the written notice (including a notice recommending a director candidate) must be

received no earlier than February 19, 2027 and no later than March 21, 2027. The notice must describe your proposal in reasonable

detail and provide certain other information required by the Company's Amended and Restated Articles of Incorporation. A copy of

the Company's Amended and Restated Articles of Incorporation is available upon request from the Company's Secretary.

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** | **Proposal** | **Board Recommendation** |
| 1 | Election of Directors | FOR ALL |
| 2 | Amend the Company's Amended and Restated Articles of Incorporation | FOR |
| 3 | Advisory (Non-binding) Vote on Executive Compensation | FOR |
| 4 | 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 25, 2026, 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 15, 2026 (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.

SEACOAST BANKING CORPORATION OF FLORIDA69 PROXY STATEMENT 2026

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, and 3 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 4 is considered a routine matter and the only proposal for which your broker or other record holders may

vote.

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 97,657,404 shares of common stock issued, outstanding and entitled to be voted, which were held

by approximately 2,127 holders of record. Therefore, at least 48,828,703 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.

SEACOAST BANKING CORPORATION OF FLORIDA70 PROXY STATEMENT 2026

To elect directors and adopt the other proposals at the 2026 Annual Meeting, the following votes are required:

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **Proposal** | **Vote Required** | **Do abstentions and** <br>**broker non-votes** <br>**count as votes cast?**<br>| **Is broker** <br>**discretionary** <br>**voting allowed?**<br>|
| 1 | Election of Directors | Plurality vote <sup>(1)</sup> | No | No |
| 2 | Amendment to the Company's Amended and Restated <br>Articles of Incorporation<br>| Affirmative vote of two-thirds <br>(66 2/3) of votes cast<br>| No | No |

| 6 | Ratification of Auditor | Affirmative vote of a majority <br>of votes cast<br>| No | Yes |

---

<sup>(1)</sup> 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.

Multiple Shareholders Sharing the Same Address

The SEC permits delivery of one copy of the proxy materials to shareholders who have the same address and last name under a

procedure referred to as "householding." We do not utilize householding for our shareholders of record. However, if you hold your

shares through a broker, bank or other nominee, you may receive only one copy of the notice and, as applicable, any additional proxy

materials that are delivered.

If you receive a single set of proxy materials as a result of householding, and you would like to have separate copies of proxy

materials mailed to you in the future, please contact your broker, bank or other nominee. However, if you want to receive a paper

proxy or notice or other proxy materials for purposes of this year's Annual Meeting, follow the instructions included in the notice

that was sent to you.

\* \* \* \*

Whether or not you plan to attend the meeting, we hope that you will vote as soon as possible. You may vote over the internet, as

well as by telephone. You also may vote your shares by requesting a paper proxy card and completing, signing and returning it by

mail. Please review the instructions on each of your voting options described in this proxy statement, as well as in the notice you

received in the mail.

APPENDIX A

INFORMATION REGARDING NON-GAAP FINANCIAL MEASUREMENTS

![](sbcf-20260410_g14.gif)

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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

\* Adjusted efficiency ratio is defined as adjusted noninterest expense less provision for credit losses on unfunded commitments and gains, losses, and expenses on

foreclosed properties divided by net operating revenues (net interest income on a fully taxable equivalent basis plus adjusted noninterest income). Beginning in 2025,

amortization of intangibles is no longer excluded from the adjusted efficiency ratios; prior periods have been updated to reflect this change.

SEACOAST BANKING CORPORATION OF FLORIDA73 PROXY STATEMENT 2026

APPENDIX B

ARTICLES OF AMENDMENT TO THE AMENDED AND RESTATED ARTICLES OF

INCORPORATION OF SEACOAST BANKING CORPORATION OF FLORIDA

![](sbcf-20260410_g14.gif)

Seacoast Banking Corporation of Florida, a corporation organized and existing under the laws of the State of Florida (the

"<u>Corporation</u>"), in accordance with the provisions of Section 607.1006 of the Florida Business Corporation Act (the "<u>FBCA</u>"),

hereby certifies as follows:

I.The name of the Corporation is Seacoast Banking Corporation of Florida.

II. After the filing and effectiveness pursuant to the FBCA of these Articles of Amendment to the Amended and Restated

Articles of Incorporation of the Corporation, at [●] on [●], 2026 (the "<u>Effective Time</u>"), shall declassify the board of

directors. Section 6.02 of the Corporation's Amended and Restated Articles of Incorporation is hereby amended to

read in its entirety as follows:

6.02 <u>Classification; Vacancies</u>. Prior to the 2026 annual meeting of shareholders, the Board of Directors,

shall be and are divided into three classes, designated Classes I, II and III, as nearly equal in number as the

then total number of directors constituting the Whole Board of Directors permits, with the term of office of

one class expiring each year. Each director elected prior to the 2026 annual meeting of shareholders shall

serve for the full term to which such director was elected. At the 2026 annual meeting of shareholders, the

director nominees whose terms expire at that meeting shall be elected to hold office until the 2027 annual

meeting of shareholders; at the 2027 annual meeting of shareholders, the director nominees whose terms

expire at that meeting shall be elected to hold office until the 2028 annual meeting of shareholders; and at the

2028 annual meeting of shareholders and each annual meeting of shareholders thereafter, all directors shall

be elected for terms of office expiring at the next annual meeting of shareholders and until a successor is

elected and qualified or until the director's prior death, resignation or removal. At each annual meeting of

shareholders beginning in 2026, successors to the directors whose terms expire at that meeting shall each be

elected for a one-year term, and prior to the 2028 annual meeting of shareholders, if the number of directors

is changed, any increase or decrease shall be apportioned among the classes so as to maintain the number of

directors in each class as nearly as may be possible to one-third (1/3) of the total number of directors. Any

vacancies in the Board of Directors for any reason, and any newly created directorships resulting from any

increase in the number of directors, may be filled only by the Board of Directors, acting by vote of (i) 66 2/3%

of the directors then in office and (ii) a majority of the Continuing Directors, although less than a quorum, or if

no directors remain by the affirmative vote of not less than (i) 66 2/3% of the Voting Shares and (ii) an

Independent Majority of Shareholders, and any directors so chosen shall hold office until the next election of

the director they have replaced and until their successors have been elected and qualified. No decrease in the

number of directors shall shorten the term of any incumbent director. Notwithstanding the foregoing, and

except as otherwise required by law, whenever the holders of any one or more series of Preferred Stock shall

have the right, voting separately as a class, to elect one or more directors of the Corporation, the terms of the

director or directors elected by such holders shall expire at the next succeeding annual meeting of

shareholders and vacancies created with respect to any directorship of the directors so elected shall be filled

in the manner specified by such series of Preferred Stock.

III. The only voting group entitled to vote on the amendments contained in these Articles of Amendment was the holders

of shares of the Corporation's Common Stock. These Articles of Amendment were duly adopted by such shareholders

on May 20, 2026, at the Corporation's annual meeting of shareholders. The number of votes cast for the amendment

above by the shareholders was sufficient for their approval.

IN WITNESS WHEREOF, Seacoast Banking Corporation of Florida has caused these Articles of Amendment to be signed by

Charles M. Shaffer its Chairman and Chief Executive Officer, this ______ day of ________________________, 2026.

Seacoast Banking Corporation of Florida

By: ____________________________________________

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Title: Chairman and Chief Executive Officer
