2 CERTAIN IMPORTANT INFORMATION CAUTION REGARDING FORWARD LOOKING STATEMENTS This presentation contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended with respect to the financial condition, liquidity, results of operations, and future performance of the business of First Guaranty Bancshares, Inc. (“First Guaranty,” the “Company” or “FGBI”). These forward-looking statements are intended to be covered by the safe harbor for “forward-looking statements” provided by the Private Securities Litigation Reform Act of 1995. Forward-looking statements are those that are not historical facts. Forward-looking statements include statements with respect to beliefs, plans, objectives, goals, expectations, anticipations, estimates and intentions that are subject to significant risks and uncertainties and are subject to change based on various factors (some of which are beyond our control). Forward-looking statements often include the words “believes,” “expects,” “anticipates,” “estimates,” “forecasts,” “intends,” “plans,” “targets,” “potentially,” “probably,” “projects,” “outlook” or similar expressions or future conditional verbs such as “may,” “will,” “should,” “would” and “could.” We caution 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. These forward-looking statements are subject to a number of factors and uncertainties, including, changes in general economic conditions, either nationally or in our market areas, that are worse than expected; competition among depository and other financial institutions; inflation and changes in the interest rate environment that reduce our margins or reduce the fair value of financial instruments; adverse changes in the securities markets; changes in laws or government regulations or policies affecting financial institutions, including changes in regulatory fees and capital requirements; our ability to consummate the acquisition of Lone Star Bank (“Lone Star”) and to realize the expected benefits of the acquisition; our ability to enter new markets successfully and capitalize on growth opportunities; our ability to successfully integrate acquired entities; changes in consumer spending, borrowing and savings habits; changes in accounting policies and practices, as may be adopted by the bank regulatory agencies, the Financial Accounting Standards Board, the Securities and Exchange Commission and the Public Company Accounting Oversight Board; changes in our organization, compensation and benefit plans; changes in our financial condition or results of operations that reduce capital available to pay dividends; increases in our provision for loan losses and changes in the financial condition or future prospects of issuers of securities that we own, which could cause our actual results and experience to differ from the anticipated results and expectations, expressed in such forward-looking statements. We undertake no obligation to publicly update any forward-looking statement, whether as a result of new information, future events or otherwise. Although we believe 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. NON-GAAP FINANCIAL MEASURES Statements included in this presentation include non-GAAP financial measures and should be read along with the accompanying tables under the section titled “Non-GAAP Reconciliations.” The Company uses non-GAAP financial measures to analyze its performance. Management believes that non-GAAP financial measures provide additional useful information that allows readers to evaluate the ongoing performance of the Company and provide meaningful comparison to its peers. Non-GAAP financial measures should not be considered as an alternative to any measure of performance or financial condition as promulgated under GAAP, and investors should consider the Company’s performance and financial condition as reported under GAAP and all other relevant information when assessing the performance or financial condition of the Company. Non-GAAP financial measures have limitations as analytical tools, and investors should not consider them in isolation or as a substitute for analysis of the results or financial condition as reported under GAAP.
