Legal Disclaimer 2 Forward-Looking Statements This presentation may contain statements that are based on management’s current estimates or expectations of future events or future results, and that may be deemed to constitute forward-looking statements as defined under the Private Securities Litigation Reform Act of 1995. These statements, including statements regarding the potential effects of the COVID-19 pandemic on the SmartFinancial’s business and financial results and conditions, are not historical in nature and can generally be identified by such words as “expect,” “anticipate,” “intend,” “plan,” “believe,” “seek,” “may,” “estimate,” and similar expressions. All forward-looking statements are subject to risks, uncertainties, and other factors that may cause the actual results of SmartFinancial to differ materially from future results expressed or implied by such forward-looking statements. Such risks, uncertainties, and other factors include, among others, (1) the risk of litigation and reputational risk associated with historic acquisition activity;(2) the risk that cost savings and revenue synergies from recently completed acquisitions may not be realized or may take longer than anticipated to realize;(3) disruption from recently completed acquisitions with customer, supplier, employee, or other business relationships;(4) our ability to successfully integrate the businesses acquired as part of previous acquisitions with the business of SmartBank;(5) risks related to the completed acquisition of Progressive Financial Group, Inc.(“PFG”);(6) the risk that the anticipated benefits from the completed acquisition of PFG may not be realized in the time frame anticipated;(7) changes in management’s plans for the future;(8) prevailing, or changes in, economic or political conditions, particularly in our market areas; (9) credit risk associated with our lending activities;(10) changes in interest rates, loan demand, real estate values, or competition;(11) changes in accounting principles, policies, or guidelines;(12) changes in applicable laws, rules, or regulations, including changes to statutes, regulations or regulatory policies or practices as a result of, or in response to, COVID-19;(13) adverse results from current or future litigation, regulatory examinations or other legal and/or regulatory actions, including as a result of the Company’s participation in and execution of government programs related to the COVID-19 pandemic;(14) the impact of the COVID-19 pandemic on the Company’s assets, business, cash flows, financial condition, liquidity, prospects and results of operations;(15) potential increases in the provision for loan losses resulting from the COVID-19 pandemic; and (16) other general competitive, economic, political, and market factors, including those affecting our business, operations, pricing, products, or services. These and other factors that could cause results to differ materially from those described in the forward-looking statements can be found in SmartFinancial’s most recent 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 Securities and Exchange Commission (the “SEC”) and available on the SEC’s website (www.sec.gov). Undue reliance should not be placed on forward-looking statements. SmartFinancial disclaims any obligation to update or revise any forward-looking statements contained in this release, 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) operating earnings, (ii) operating return on average assets, (iii) operating return on average shareholder equity, (iv) return on average tangible common equity, (v) operating return on average tangible common equity, (vi) operating efficiency ratio;(vii) tangible common equity;(viii) average tangible common equity;(ix) tangible book value;(x) operating pre-tax pre-provision earnings;(xi) operating noninterest income;(xii) operating noninterest expense; and ratios derived therefrom, in its analysis of the company's performance. Operating earnings excludes the following from net income: securities gains and losses, merger termination fee of $6.4 million in the second quarter of 2019, merger related and restructuring expenses, tax benefit from director options previously exercised, and the income tax effect of adjustments. Operating return on average assets is the annualized operating earnings (Non-GAAP) divided by average assets. Operating return on average shareholder equity is the annualized operating earnings (Non-GAAP) divided by average equity. Return on average tangible common equity is the annualized net income divided by average tangible common equity (Non-GAAP). Operating return on average tangible common equity is the annualized operating earnings (Non-GAAP) divided by average tangible common equity (Non-GAAP). The operating efficiency ratio includes an adjustment for taxable equivalent yields and excludes securities gains and losses and merger related and restructuring expenses from the efficiency ratio. Tangible common equity and average tangible common equity excludes goodwill and other intangible assets from shareholders’ equity and average shareholders’ equity. Tangible book value excludes goodwill and other intangible assets less shareholders’ equity divided by common shares outstanding. Operating pre-tax pre-provision earnings is net interest income plus operating noninterest income (Non-GAAP) less operating noninterest expense (Non-GAAP). Operating noninterest income excludes the following from noninterest income: securities gains and losses, expenses related to the termination of the ADECA loan program and the merger termination fee of $6.4 million in the second quarter of 2019. Operating noninterest expense excludes the following from noninterest expense: prior year adjustments to salaries, merger related and restructuring expenses and certain franchise tax true-up expenses. Management believes that Non-GAAP financial measures provide additional useful information that allows investors to evaluate the ongoing performance of the company and provide meaningful comparisons to its peers. Management believes these non-GAAP financial measures also enhance investors' ability to compare period-to-period financial results and allow investors and company management to view our operating results excluding the impact of items that are not reflective of the underlying operating performance. 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.
