Certain statements in this presentation are forward-looking statements that reflect our current views with respect to, among other things, future events and our financial and operational 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,” “aspire,” “estimate,” “intend,” “plan,” “project,” “projection,” “forecast,” “roadmap,” “goal,” “target,” “guidance,” “would,” and “outlook,” or the negative version of those words or other comparable words 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. The inclusion of these forward-looking statements should not be regarded as a representation by us or any other person that such expectations, estimates and projections will be achieved. Accordingly, 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. 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. 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 acceptance by customers of Athens of the Company’s products and services; the ability of the Company to meet expectations regarding the benefits, costs, synergies, and financial and operational impact of the Athens merger; the possibility that any of the anticipated benefits, costs, synergies and financial and operational improvements of the Athens merger will not be realized or will not be realized as expected; the possibility that the Athens merger integration may be more expensive or take more time to complete than anticipated; the opportunities to enhance market share in certain markets and acceptance of the Company generally in new markets; economic conditions (including interest rate environment, government economic and monetary policies, the strength of global financial markets and inflation and deflation) that impact the financial services industry as a whole and/or our business; the concentration of our business in the Nashville metropolitan statistical area (“MSA”) and in Tennessee, and the effect of changes in the economic, political and environmental conditions on this market; increased competition in the financial services industry, locally, regionally or nationally, which may adversely affect pricing and the other terms offered to our clients; an increase in the cost of deposits, loss of deposits or a change in the deposit mix, which could increase our cost of funding; an increase in the costs of capital, which could negatively affect our ability to borrow funds, successfully raise additional capital or participate in strategic acquisition opportunities; our dependence on our management team and board of directors and changes in our management and board composition; our reputation in the community; our ability to execute our strategy and to achieve our loan ROAA and efficiency ratio goals, hire seasoned bankers, loan and deposit growth through organic growth and strategic acquisitions; credit risks related to the size of our borrowers and our ability to adequately identify, assess and limit our credit risk; our concentration of large loans to a small number of borrowers; the significant portion of our loan portfolio that originated during the past two years and therefore may less reliably predict future collectability than older loans; the adequacy of reserves (including our allowance for loan losses) and the appropriateness of our methodology for calculating such reserves; non-performing loans and leases; non-performing assets; charge-offs, non-accruals, troubled debt restructurings, impairments and other credit-related issues; adverse trends in the healthcare service industry, which is an integral component of our market’s economy; our management of risks inherent in our commercial real estate loan portfolio, and the risk of a prolonged downturn in the real estate market, which could impair the value of our collateral and our ability to sell collateral upon any foreclosure; governmental legislation and regulation, including changes in the nature and timing of the adoption and effectiveness of new requirements under the Dodd-Frank Act of 2010, as amended, Basel guidelines, capital requirements, accounting regulation or standards and other applicable laws and regulations; the impact of the Tax Cuts and Job Act of 2017, as amended, on the Company and its financial performance and results of operations; the loss of large depositor relationships, which could force us to fund our business through more expensive and less stable sources; operational and liquidity risks associated with our business, including liquidity risks inherent in correspondent banking; volatility in interest rates and our overall management of interest rate risk, including managing the sensitivity of our interest-earning assets and interest-bearing liabilities to interest rates, and the impact to our earnings from a change in interest rates; the potential for our bank’s regulatory lending limits and other factors related to our size to restrict our growth and prevent us from effectively implementing our business strategy; strategic acquisitions we may undertake to achieve our goals; the sufficiency of our capital, including sources of capital and the extent to which we may be required to raise additional capital to meet our goals; fluctuations in the fair value of our investment securities that are beyond our control; deterioration in the fiscal position of the U.S. government and downgrades in Treasury and federal agency securities; potential exposure to fraud, negligence, computer theft and cyber-crime; the adequacy of our risk management framework; our dependence on our information technology and telecommunications systems and the potential for any systems failures or interruptions; threats to and breaches of our information technology systems and data security, including cyber-attacks; our dependence upon outside third parties for the processing and handling of our records and data; our ability to adapt to technological change; the financial soundness of other financial institutions; our exposure to environmental liability risk associated with our lending activities; our engagement in derivative transactions; our involvement from time to time in legal proceedings and examinations and remedial actions by regulators; the susceptibility of our market to natural disasters and acts of God; and the effectiveness of our internal controls over financial reporting and our ability to remediate any future material weakness in our internal controls over financial reporting. The foregoing factors should not be construed as exhaustive and should be read in conjunction with those factors that are detailed from time to time in the Company’s periodic and current reports filed with the Securities and Exchange Commission, including those factors included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 under the headings “Item 1A. Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements” and in the Company’s Quarterly Reports on Form 10-Q and 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 our forward-looking statements. Accordingly, you should not place undue reliance on any such forward-looking statements. Any forward-looking statement speaks only as of the date of this presentation, and we do not undertake any obligation to publicly update or review any forward-looking statement, whether as a result of new information, future developments or otherwise, except as required by law. New risks and uncertainties may emerge from time to time, and it is not possible for us to predict their occurrence or how they will affect us. Safe Harbor Statements

Unwound $20MM notional of fixed to floating interest rate swaps. Lowered rates on time deposits and shortened duration of wholesale liabilities to under 3 months. Relationship managers are proactively meeting with clients regarding opportunities to optimize deposit costs with potential rate cuts.
