Forward-looking statements include statements with respect to the Company's beliefs, plans, objectives, goals, expectations, anticipations, assumptions, estimates, and intentions about future performance, and involve known and unknown risks, uncertainties and other factors, which may be beyond the Company's control, and which may cause the actual results, performance or achievements of Seacoast Banking Corporation of Florida (“Seacoast” or the “Company”) or its wholly-owned banking subsidiary, Seacoast National Bank (“Seacoast Bank”), to be materially different from those set forth in the forward-looking statements.
