SEACOAST BANKING CORP OF FLORIDA

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
