Important Information Forward-Looking Statements Certain of the statements made in this presentation may constitute 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. Such forward-looking statements, including statements regarding the intent, belief, or current expectations of SmartFinancial’s management regarding the company’s strategic direction, prospects, or future results or the benefits of the proposed merger with Foothills Bancorp, Inc. (the “proposed transaction”), are subject to numerous risks and uncertainties. Such risks and uncertainties include, among others, (1) expected revenue synergies and cost savings from the proposed transaction or the recently completed mergers with Tennessee Bancshares, Inc. (the “Tennessee Bancshares merger”) and Capstone Bancshares, Inc. (the “Capstone merger”) may not be fully realized or may take longer than anticipated to be realized, (2) disruption from the proposed transaction, the Tennessee Bancshares merger, or the Capstone merger with customers, suppliers, or employee or other business relationships, (3) the occurrence of any event, change, or other circumstances that could give rise to the termination of the agreement and plan of merger for the proposed transaction, (4) the risk of successful integration of the businesses of SmartFinancial and Foothills Bancorp, Inc. following the proposed transaction, (5) the failure of Foothills Bancorp’s shareholders to approve the agreement and plan of merger, (6) the amount of costs, fees, expenses, and charges related to the proposed transaction, (7) risks of expansion into new geographic or product markets, like the recent expansion into the Nashville, TN MSA associated with the Tennessee Bancshares merger, (8) the ability to obtain required governmental and regulatory approvals for the proposed transaction, (9) reputational risk and the reaction of the parties’ customers to the proposed transaction, (10) the failure of the conditions to closing of the proposed transaction to be satisfied, (11) the possibility that the proposed transaction may be more expensive to complete than anticipated, including as a result of unexpected factors or events, (12) the dilution caused by SmartFinancial’s issuance of additional shares of its common stock in the proposed transaction, (13) changes in SmartFinancial’s management’s plans for the future, (14) prevailing economic and political conditions, particularly in SmartFinancial's market areas, (15) credit risk associated with SmartFinancial's lending activities, (16) changes in interest rates, loan demand, real estate values, and competition, (17) changes in accounting principles, policies, or guidelines, (18) changes in applicable laws, rules, or regulations, and (19) other competitive, economic, political, and market factors affecting SmartFinancial's business, operations, pricing, products, and services. Certain additional factors which could affect the forward-looking statements can be found in SmartFinancial’s annual report on Form 10-K, quarterly reports on Form 10-Q, and current reports on Form 8-K, in each case filed with or furnished to the SEC and available on the SEC’s website (www.sec.gov). SmartFinancial disclaims any obligation to update or revise any forward-looking statements contained in this presentation, which speak only as of the date hereof, whether as a result of new information, future events, or otherwise. Non-GAAP Financial Measures Statements included in this presentation include non-GAAP financial measures and should be read along with the accompanying tables, which provide a reconciliation of non-GAAP financial measures to GAAP financial measures. SmartFinancial management uses several non-GAAP financial measures, including: (i) core net income; (ii) core efficiency ratio; (iii) tangible common equity, (iv) return on average assets excluding certain items and (v) return on average tangible common equity excluding certain items in its analysis of the company’s performance. Each of core net income and return on average assets excludes the following from net income available to common shareholders: securities gains and losses, merger-related expenses, amortization of intangibles and goodwill impairment, and the effect of the December, 2017 tax law change on deferred tax assets, and the income tax effect of adjustments. The core efficiency ratio excludes securities gains and losses and merger-related expenses, along with expenses related to foreclosure and repossession of assets, from the efficiency ratio. Tangible common equity excludes goodwill and other intangible assets. Return on average tangible common equity represents annualized or year-to-date core net income available to common shareholders as a percent of average tangible common equity. 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 comparisons 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 SmartFinancial'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. 2
