CenterState has filed a registration statement on Form S-4 with the SEC to register the shares of CenterState’s common stock that will be issued to NCC’s stockholders in connection with the proposed merger. The registration statement includes a joint proxy statement of CenterState and NCC and a prospectus of CenterState. A definitive joint proxy statement-prospectus will be sent to the stockholders of each of CenterState and NCC in connection with the proposed merger.  INVESTORS AND SECURITY HOLDERS ARE URGED TO READ THE REGISTRATION STATEMENT AND DEFINITIVE JOINT PROXY STATEMENT-PROSPECTUS WHEN IT BECOMES AVAILABLE (AND ANY OTHER DOCUMENTS FILED WITH THE SEC IN CONNECTION WITH THE PROPOSED MERGER OR INCORPORATED BY REFERENCE INTO THE JOINT PROXY STATEMENT-PROSPECTUS) BECAUSE SUCH DOCUMENTS WILL CONTAIN IMPORTANT INFORMATION REGARDING THE PROPOSED MERGER.

Forward-Looking Statements

Certain statements contained in this report that are not statements of historical fact constitute forward-looking statements for which NCC claims the protection of the safe harbor provisions contained in the Private Securities Litigation Reform Act of 1995 (the “Act”), notwithstanding that such statements are not specifically identified as such. In addition, certain statements may be contained in NCC’s future filings with the SEC, in press releases and in oral and written statements made by NCC or with NCC’s approval that are not statements of historical fact and that constitute forward-looking statements within the meaning of the Act. Examples of forward-looking statements include, but are not limited to: (a) projections of revenues, expenses, income or loss, earnings or loss per share, the payment or nonpayment of dividends, capital structure and other financial items; (b) statements of NCC’s plans, objectives and expectations or those of its management or Board of Directors, including those relating to the proposed merger with CenterState; (c) statements of future economic performance; and (d) statements of assumptions underlying such statements. Words such as “believes,” “anticipates,” “expects,” “intends,” “targeted,” “continue,” “remain,” “will,” “should,” “may” and other similar expressions are intended to identify forward-looking statements but are not the exclusive means of identifying such statements. Forward-looking statements are subject to various risks and uncertainties, including those risks and uncertainties described under the heading “Risk Factors” in NCC’s Annual Report on Form 10-K for the year ended December 31, 2017, and described in any subsequent reports that NCC has filed with the SEC. With respect to the pending merger with CenterState, these risks include, among others: (1) the risk that the cost savings and any revenue synergies from the merger may not be realized or take longer than anticipated to be realized; (2) disruption from the merger with customers, suppliers, employees or other business partners; (3) the occurrence of any event, change or other circumstances that could give rise to the termination of the merger agreement; (4) the risk of successful integration of NCC’s businesses into CenterState; (5) the failure to obtain required governmental approvals of the merger; (6) the failure to obtain the necessary stockholder or shareholder approvals, as applicable, in connection with the merger; (7) the amount of the costs, fees, expenses and charges related to the merger; (8) reputational risk and the reaction of each company’s customers, suppliers, employees or other business partners to the merger; (9) the failure of the closing conditions in the merger agreement to be satisfied, or any unexpected delay in closing the merger; (10) the risk that the integration of NCC’s operations into the operations of CenterState will be materially delayed or will be more costly or difficult than expected; (11) the possibility that the merger may be more expensive to complete than anticipated, including as a result of unexpected factors or events; and (12) general competitive, economic, political and market conditions. There are or will be important factors that could cause actual outcomes or results to differ materially from those indicated in forward-looking statements, and these forward-looking statements should not be relied upon as predictions of future events. NCC undertakes no obligation to update any forward-looking statements or to make any other forward-looking statements, whether as a result of new information, future events or otherwise. In that respect, NCC cautions readers not to place undue reliance on any such forward-looking statements, which speak only as of the date made.
