Restricted stock financial

"Restricted stock issued from Seacoast's 2021 Incentive Plan for service as a Director in 2026"

Shares granted to an individual that carry limits on transfer or sale until certain conditions are met, such as staying with the company for a set time or hitting performance targets. Think of them as a locked gift that gradually opens; for investors they matter because they affect how many shares may enter the market later, signal management incentives and potential dilution, and reveal confidence in future company performance.

2021 Incentive Plan financial

"Restricted stock issued from Seacoast's 2021 Incentive Plan for service as a Director in 2026"

Directors Deferred Compensation Plan financial

"deferred into director's account in Seacoast's Directors Deferred Compensation Plan"

A directors deferred compensation plan lets a board member postpone receiving part or all of their cash fees or stock-based pay until a future date, often retirement, allowing taxes to be delayed and payouts to be structured over time. Investors care because these plans change a company’s future cash obligations and reveal how the board’s pay is aligned with long-term performance—like choosing to take a paycheck later to tie personal reward to the company’s future results.

Non-employee Directors Deferred Compensation Plan financial

"Held in Seacoast's Non-employee Directors Deferred Compensation Plan"
