Annual Shareholder Meeting | May 24, 2016 Exhibit 99.1

Forward-Looking Statement The Private Securities Litigation Reform Act of 1995 provides a “safe harbor” for forward-looking statements. Any forward-looking statement is not a guarantee of future performance and actual future results could differ materially from those contained in forward-looking information. Factors that could cause or contribute to such differences include, without limitation, risks and uncertainties detailed from time to time in the Company’s filings with the Securities and Exchange Commission, including, without limitation, the risk factors disclosed in Item 1A, “Risk Factors.” In the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2014. Many of these factors are beyond the Company’s ability to control or predict, and readers are cautioned not to put undue reliance on these forward-looking statements. The following list, which is not intended to be an all-encompassing list of risks and uncertainties affecting the Company, summarizes several factors that could cause the Company’s results to differ materially from those anticipated or expected in these forward-looking statements: Conditions in the financial markets, the real estate markets and economic conditions generally. Enactment of new legislation and increased regulatory oversight. Changes in interest rates. Future expansions including new branch openings, acquisition of other financial institutions and new business lines or new product or service offerings. Increased competition with other banks, savings and loan associations, credit unions, mortgage banking, insurance companies, securities brokerage and asset management firms. Changes in accounting standards Other factors not currently anticipated may also materially and adversely affect the Company’s results of operations, cash flows and financial position. There can be no assurance that future results will meet expectations. While the Company believes that the forward-looking statements in this presentation are reasonable, you should not place undue reliance on any forward-looking statement. In addition, these statements speak only as of the date made. The Company does not undertake, and expressly disclaims, any obligation to update or alter any statements whether as a result of new information, future events or otherwise, except as may be required by applicable law.
