First Quarter 2017 Investor Presentation Exhibit 99.1

This investor presentation contains “forward-looking statements” within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical fact are forward-looking statements. You can identify these forward-looking statements in some cases through the Company’s use of words such as “believes,” “anticipates,” “expects,” “may,” “will,” “assumes,” “should,” “predicts,” “could,” “would,” “intends,” “targets,” “estimates,” “projects,” “plans,” “potential” and other similar words and expressions of the future or otherwise regarding the Company’s proposed acquisition of the Clayton Banks, the anticipated benefits and financial impact thereof, the outlook for the Company’s future business and financial performance, including the outlook for the Company’s mortgage business, and/or the performance of the banking industry and economy in general. These forward-looking statements include, without limitation, statements relating to the Company’s outlook for its mortgage business, anticipated benefits, financial impact and closing of the proposed acquisition by the Company of the Clayton Banks, including, the anticipated timing of the closing of the proposed acquisition, any expected increase in the Company’s earnings per share and any expected earn-back period related to dilution in tangible book value resulting from the proposed acquisition, acceptance by the customers of the Clayton Banks the Company’s products and services, the opportunities to enhance market share in certain markets, market acceptance of the Company generally in new markets, expectations regarding future investment in the Clayton Banks’ markets and the integration of the Clayton Banks’ operations. Forward-looking statements are based on the information known to, and current beliefs and expectations of, the Company’s management and are subject to significant risks and uncertainties. Actual results may differ materially from those contemplated by such forward-looking statements. A number of important factors could cause actual results to differ materially from those contemplated by the forward-looking statements in this investor presentation including, without limitation, general economic factors affecting the Company’s mortgage business, the parties’ ability to consummate the acquisition or satisfy the conditions to the completion of the proposed acquisition of the Clayton Banks, the receipt of regulatory approvals required for the acquisition on the terms expected or on the anticipated schedule, the parties’ ability to meet expectations regarding the timing and completion and accounting and tax treatment of the acquisition, the possibility that any of the anticipated benefits of the proposed acquisition will not be fully realized or will not be realized within the expected time period, the risk that integration of the Clayton Banks’ operations with those of the Company will be materially delayed or will be more costly or difficult than expected, the failure of the proposed acquisition to close for any other reason, the effect of the announcement of the proposed acquisition on employee and customer relationships and operating results (including, without limitation, difficulties in maintaining relationships with employees and customers), dilution caused by the Company’s issuance of additional shares of its common stock in connection with the proposed acquisition, the possibility that the proposed acquisition may be more expensive to complete than anticipated, including as a result of unexpected factors or events; general competitive, economic, political and market conditions and fluctuations, and the other factors described in the Company’s final prospectus filed pursuant to Rule 424(b)(3) under the Securities Act, as amended, filed with the U.S. Securities and Exchange Commission on September 19, 2016 (Registration No. 333-213210) under the captions “Cautionary note regarding forward-looking statements” and “Risk factors”. Many of these factors are difficult to foresee and are beyond the Company’s ability to control or predict. The Company believes the forward-looking statements contained herein are reasonable; however, undue reliance should not be placed on any forward-looking statements, which are based on current expectations and speak only as of the date that they are made. The Company does not assume any obligation to update any forward-looking statements as a result of new information, future developments or otherwise, except as otherwise may be required by law.  Forward looking statements

Use of non-GAAP financial measures This presentation contains certain financial measures that are not measures recognized under U.S. generally accepted accounting principles (GAAP) and therefore are considered non-GAAP financial measures. The Company’s management uses these non-GAAP financial measures in their analysis of the Company’s performance, financial condition and the efficiency of its operations. Management believes that these non-GAAP financial measures provide a greater understanding of ongoing operations and enhance comparability of results with prior periods as well as demonstrating the effects of significant gains and charges in the current period. The Company’s management also believes that investors find these non-GAAP financial measures useful as they assist investors in understanding our underlying operating performance and the analysis of ongoing operating trends. However, the non-GAAP financial measures discussed herein should not be considered in isolation or as a substitute for the most directly comparable or other financial measures calculated in accordance with GAAP. Moreover, the manner in which we calculate the non-GAAP financial measures discussed herein may differ from that of other companies reporting measures with similar names. You should understand how such other banking organizations calculate their financial measures similar or with names similar to the non-GAAP financial measures we have discussed herein when comparing such non-GAAP financial measures. Below is a listing of the non-GAAP financial measures used in this presentation. Net Interest Income on a tax-equivalent basis is a non-GAAP measure that adjusts for the tax-favored status of net interest income from loans and investments. We believe this measure to be the preferred industry measurement of net interest income as it enhances comparability of net interest income arising from taxable and tax-exempt sources. The most directly comparable financial measure calculated in accordance with GAAP is net interest income. Net interest margin on a tax-equivalent basis is net interest income on a tax-equivalent basis divided by average interest-earning assets on a tax-equivalent basis. We believe this measure to be the preferred industry measurement of net interest margin as it enhances comparability of net interest income arising from taxable and tax-exempt sources. The most directly comparable financial measure calculated in accordance with GAAP is net interest margin. The adjusted efficiency ratio is a non-GAAP measure that excludes securities gains (losses), merger-related and conversion expenses, one time IPO equity grants and other selected items. The Company’s management uses this measure in their analysis of the Corporation's performance. The Company’s management believes this measure provides a greater understanding of ongoing operations and enhances comparability of results with prior periods, as well as demonstrates the effects of significant gains and charges. The most directly comparable financial measure calculated in accordance with GAAP is the efficiency ratio. Tangible book value per common share and tangible common equity to tangible assets are non-GAAP measures that exclude the impact of goodwill and other intangibles used by the Company’s management to evaluate capital adequacy. Because intangible assets such as goodwill and other intangibles vary extensively from company to company, we believe that the presentation of this information allows investors to more easily compare the Company’s capital position to other company companies. The most directly comparable financial measure calculated in accordance with GAAP is book value per common share and our total shareholder’s equity to total assets. Core deposits is a non-GAAP financial measure used by management and investors to evaluate organic growth of deposits and the quality of deposits as a funding source. We calculate core deposits by excluding jumbo time deposits (greater than $250,000) from total deposits. The most directly comparable financial measure calculated in accordance with GAAP is total deposits. A reconciliation of these non-GAAP financial measures to the most directly comparable GAAP measures are provided on the appendix to this presentation.
