Forward-Looking Statements This presentation contains forward-looking statements. Any statements about Triumph Bancorp, Inc.’s (“Triumph,” “TBK,” “we,” “us” or “our”) expectations, beliefs, plans, predictions, forecasts, objectives, assumptions or future events or performance are not historical facts and may be forward-looking. You can identify forward-looking statements by the use of forward-looking terminology such as “believes,” “expects,” “could,” “may,” “will,” “should,” “seeks,” “likely,” “intends,” “goal,” “plans,” “pro forma,” “projects,” “estimates” or “anticipates” or the negative of these words and phrases or similar words or phrases that are predictions of or indicate future events or trends and that do not relate solely to historical matters. You can also identify forward-looking statements by discussions of strategy, plans or intentions. Forward-looking statements involve numerous risks and uncertainties and you should not rely on them as predictions of future events. Forward-looking statements depend on assumptions, data or methods that may be incorrect or imprecise and we may not be able to realize them. We do not guarantee that the transactions and events described will happen as described (or that they will happen at all). The following factors, among others, could cause actual results and future events to differ materially from those set forth or contemplated in the forward-looking statements: business and economic conditions generally and in the bank and non-bank financial services industries, nationally and within our local market areas; our ability to mitigate our risk exposures; our ability to maintain our historical earnings trends; risks related to the integration of acquired businesses (including our acquisitions of First Bancorp of Durango, Inc., Southern Colorado Corp., and the operating assets of Interstate Capital Corporation and certain of its affiliates) and any future acquisitions; changes in management personnel; interest rate risk; concentration of our factoring services in the transportation industry; credit risk associated with our loan portfolio; lack of seasoning in our loan portfolio; deteriorating asset quality and higher loan charge-offs; time and effort necessary to resolve nonperforming assets; inaccuracy of the assumptions and estimates we make in establishing reserves for probable loan losses and other estimates; lack of liquidity; fluctuations in the fair value and liquidity of the securities we hold for sale; impairment of investment securities, goodwill, other intangible assets, or deferred tax assets; our risk management strategies; environmental liability associated with our lending activities; increased competition in the bank and non-bank financial services industries, nationally, regionally, or locally, which may adversely affect pricing and terms; the accuracy of our financial statements and related disclosures; material weaknesses in our internal control over financial reporting; system failures or failures to prevent breaches of our network security; the institution and outcome of litigation and other legal proceedings against us or to which we become subject; changes in carry-forwards of net operating losses; changes in federal tax law or policy; the impact of recent and future legislative and regulatory changes, including changes in banking, securities, and tax laws and regulations, such as the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) and their application by our regulators; governmental monetary and fiscal policies; changes in the scope and cost of the Federal Deposit Insurance Corporation insurance and other coverages; failure to receive regulatory approval for future acquisitions; and increases in our capital requirements. While forward-looking statements reflect our good-faith beliefs, they are not guarantees of future performance. All forward-looking statements are necessarily only estimates of future results. Accordingly, actual results may differ materially from those expressed in or contemplated by the particular forward-looking statement, and, therefore, you are cautioned not to place undue reliance on such statements. Further, any forward-looking statement speaks only as of the date on which it is made, and we undertake no obligation to update any forward-looking statement to reflect events or circumstances after the date on which the statement is made or to reflect the occurrence of unanticipated events or circumstances, except as required by applicable law. For a discussion of such risks and uncertainties, which could cause actual results to differ from those contained in the forward-looking statements, see “Risk Factors” and the forward-looking statement disclosure contained in our Annual Report on Form 10-K, filed with the Securities and Exchange Commission on February 12, 2019.
