Effective November 3, 2017, Seacoast Banking Corporation of Florida, a Florida corporation (“Seacoast” or the “Company”), completed its previously announced merger (the “Merger”) with Palm Beach Community Bank, a Florida corporation (“PBCB”), pursuant to an Agreement and Plan of Merger (the “Merger Agreement”), dated May 4, 2017, by and among Seacoast, Seacoast’s wholly-owned subsidiary, Seacoast National Bank, a national banking association (“Seacoast National”) and PBCB. At the effective time of the Merger (the “Effective Time”), PBCB merged with and into Seacoast National, with Seacoast National continuing as the surviving bank.

Pursuant to the Merger Agreement, each share of PBCB common stock issued and outstanding immediately prior to the Effective Time was converted into the right to receive (i) 0.9240 (the “Exchange Ratio”) of a share of Seacoast common stock (subject to the payment of cash in lieu of fractional shares) and (ii) $6.26 in cash, or a total value of $28.57 per share of PBCB common stock. The resulting aggregate merger consideration paid by Seacoast was approximately $71.6 million. Each share of Seacoast common stock outstanding immediately prior to the Merger remained outstanding and was unaffected by the Merger.

Immediately prior to the Merger, outstanding PBCB stock options were terminated and exchanged for an aggregate amount in cash, without interest, equal to the product of (i) the aggregate number of shares of PBCB common stock subject to such options immediately prior to their termination multiplied by (ii) the excess, if any, of the value of the merger consideration, over the exercise price per share of the options.

The foregoing description of the Merger and the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, which is included as Exhibit 2.1 to this Current Report on Form 8-K and is incorporated by reference herein.

On November 3, 2017, the Company issued a press release announcing the completion of the Merger. A copy of the press release is included as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated by reference herein.
