ARCZYNSKI DENNIS J 4

What Happened

• Dennis J. Arczynski, a director of Seacoast Banking Corporation of Florida (SBCF), exercised 3,419 stock options and immediately sold the resulting 3,419 shares on Feb 3, 2026. The options were exercised at $14.39 per share (total intrinsic cost $49,199) and the shares were sold in an open-market transaction at $34.21 per share (total proceeds $116,964). The Form 4 shows the option/derivative position was correspondingly disposed (converted).

Context

• This is a common “exercise-and-sell” (cashless) sequence: the director exercised options and sold the immediate resulting shares the same day. Such transactions typically reflect option vesting or routine liquidity; they do not necessarily indicate a change in long-term confidence. The derivative line showing disposal at $0 reflects conversion/surrender of the option instrument when exercised.
