SEACOAST BANKING CORP OF FLORIDA

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.
