 This investor presentation contains “forward-looking statements” 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 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 outlook for the Company’s future business and financial performance and/or the performance of the banking and mortgage industry and economy in general and the Company’s acquisition of the Clayton Banks and the benefits, cost, and financial impact thereof. Investors are cautioned that any such forward-looking statements are not guarantees of future performance and involve known and unknown risks and uncertainties which may cause the actual results, performance or achievements of the Company to be materially different from the future results, performance or achievements expressed or implied by such forward-looking statements. 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 factors could cause actual results to differ materially from those contemplated by the forward-looking statements in this investor presentation including, without limitation, the risks and other factors set forth in the Company’s Annual Report Form 10-K for the year ended December 31, 2016, filed with the SEC on March 31, 2017 under the captions “Cautionary note regarding forward-looking statements” and “Risk factors.” Many of these factors 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.

Market Data Market data used in this investor presentation has been obtained from government and independent industry sources and publications available to the public, sometimes with a subscription fee, as well as from research reports prepared for other purposes. Industry publications and surveys and forecasts generally state that the information contained therein has been obtained from sources believed to be reliable. We did not commission the preparation of any of the sources or publications referred to in this presentation. We have not independently verified the data obtained from these sources, and, although we believe such data to be reliable as of the dates presented, it could prove to be inaccurate.

 Use of non-GAAP financial measures  This investor 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 demonstrate 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 investor presentation. Core net income, core diluted earning per share, the core efficiency ratio, and core return on average assets and equity are non-GAAP measures that exclude securities gains (losses), merger-related and conversion expenses, one time IPO equity grants and other selected items. The Company’s management use these measures in their analysis of the Company’s performance. The Company’s management believes these measures provide a greater understanding of ongoing operations and enhance comparability of results with prior periods, as well as demonstrate the effects of significant gains and charges. 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 and are 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 these non-GAAP financial measures allows investors to more easily compare the Company’s capital position to other companies. A reconciliation of these non-GAAP financial measures to the most directly comparable GAAP measures are provided on the appendix to this investor presentation.
