There will be no sale of securities in any jurisdiction in which such an offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction. No offer of securities shall be made except by means of a prospectus meeting the requirement of Section 10 of the Securities Act of 1933, as amended. NON-GAAP FINANCIAL MEASURES This presentation contains certain non-GAAP (generally accepted accounting principles) financial measures, including tangible equity and tangible book value per share. The non-GAAP financial measures that the Company discusses in this presentation should not be considered in isolation or as a substitute for the most directly comparable or other financial measures calculated in accordance with GAAP. A reconciliation of the non-GAAP financial measures used in this presentation to the most directly comparable GAAP measures is provided at the end of this presentation. FORWARD LOOKING STATEMENTS This presentation contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. These forward‑looking statements reflect the Company’s current views with respect to, among other things, future events and its financial performance. These statements are often, but not always, made through the use of words or phrases such as “may,” “should,” “could,” “predict,” “potential,” “believe,” “will likely result,” “expect,” “continue,” “will,” “anticipate,” “seek,” “estimate,” “intend,” “plan,” “projection,” “would” and “outlook,” or the negative version of those words or other comparable words or phrases of a future or forward‑looking nature. These forward‑looking statements are not historical facts, and are based on current expectations, estimates and projections about our industry, management’s beliefs and certain assumptions made by management, many of which, by their nature, are inherently uncertain and beyond our control. Accordingly, the Company cautions you that any such forward‑looking statements are not guarantees of future performance and are subject to risks, assumptions and uncertainties that are difficult to predict. Although the Company believes that the expectations reflected in these forward‑looking statements are reasonable as of the date made, actual results may prove to be materially different from the results expressed or implied by the forward‑looking statements. There are or will be important factors that could cause our actual results to differ materially from those indicated in these forward‑looking statements, including, but not limited to, the following: the effect of Hurricane Harvey on our markets and business; natural disasters and adverse weather, acts of terrorism, an outbreak of hostilities or other international or domestic calamities, and other matters beyond our control; the geographic concentration of our markets in Beaumont and Houston, Texas; our ability to prudently manage our growth and execute our strategy; risks associated with our acquisition and de novo branching strategy; changes in management personnel; the amount of nonperforming and classified assets that we hold; time and effort necessary to resolve nonperforming assets; deterioration of our asset quality; interest rate risk associated with our business; business and economic conditions generally and in the financial services industry, nationally and within our primary markets; volatility and direction of oil prices and the strength of the energy industry, generally and within Texas; the composition of our loan portfolio, including the identity of our borrowers and the concentration of loans in specialized industries; changes in the value of collateral securing our loans; our ability to maintain important deposit customer relationships and our reputation; our ability to maintain effective internal control over financial reporting; operational risks associated with our business; increased competition in the financial services industry, particularly from regional and national institutions; volatility and direction of market interest rates; liquidity risks associated with our business; systems failures or interruptions involving our information technology and telecommunications systems or third‑party servicers; environmental liability associated with our lending activities; the institution and outcome of litigation and other legal proceedings against us or to which we may become subject; changes in the laws, rules, regulations, interpretations or policies relating to financial institution, accounting, tax, trade, monetary and fiscal matters; the effects of the Tax Cuts and Jobs Act; and further government intervention in the U.S. financial system. The foregoing factors should not be construed as exhaustive and should be read together with the other cautionary statements included under “Cautionary Note Regarding Forward-Looking Statements” and “Risk Factors” in the Company’s Annual Report on Form 10-K filed with the SEC on March 23, 2018 and any updates to those risk factors set forth in the Company’s subsequent Quarterly Reports on Form 10-Q or Current Reports on Form 8-K. If one or more events related to these or other risks or uncertainties materialize, or if our underlying assumptions prove to be incorrect, actual results may differ materially from what we anticipate. Accordingly, you should not place undue reliance on any such forward‑looking statements. Any forward‑looking statement speaks only as of the date on which it is made, and the Company does not undertake any obligation to publicly update or review any forward‑looking statement, whether as a result of new information, future developments or otherwise. New factors emerge from time to time, and it is not possible for the Company to predict which will arise. In addition, the Company cannot assess the impact of each factor on its business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward‑looking statements. All forward-looking statements, expressed or implied, included in this communication are expressly qualified in their entirety by this cautionary statement. This cautionary statement should also be considered in connection with any subsequent written or oral forward-looking statements that the Company or persons acting on the Company’s behalf may issue. Annualized, pro forma, projected and estimated numbers are used for illustrative purpose only, are not forecasts and may not reflect actual results. SAFE HARBOR STATEMENT
