DISCLOSURES 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 on SmartFinancial Inc.’s (“SmartFinancial”) 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) changes in management’s plans for the future; (6) prevailing, or changes in, economic or political conditions, particularly in our market areas, including the effects of declines in the real estate market, inflationary pressures, elevated interest rates and slowdowns in economic growth, as well as the financial stress on borrowers as a result of the foregoing; (7) increased technology and cybersecurity risks, including generative artificial intelligence risks; (8) credit risk associated with our lending activities; (9) changes in loan demand, real estate values, or competition; (10) developments in our mortgage banking business, including loan modifications, general demand, and the effects of judicial or regulatory requirements or guidance; (11) changes in accounting principles, policies, or guidelines; (12) changes in applicable laws, rules, or regulations; (13) adverse results from current or future litigation, regulatory examinations or other legal and/or regulatory actions, including as a result of SmartFinancial’s participation in and execution of government programs related to the COVID-19 pandemic and related variants; (14) potential impacts of adverse developments in the banking industry highlighted by high-profile bank failures, including impacts on customer confidence, deposit outflows, liquidity and the regulatory response thereto; (15) significant turbulence or a disruption in the capital or financial markets and the effect of a fall in stock market prices on our investment securities; (16) the effects of war or other conflicts including the impacts related to or resulting from Russia’s military action in Ukraine or the conflict in Israel and surrounding areas; and (17) 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 revenue, (ii) operating earnings, (iii) operating return on average assets, (iv) operating return on average shareholders’ equity, (v) return on average tangible common equity, (vi) operating return on average tangible common equity, (vii) operating efficiency ratio; (viii) tangible common equity; (ix) average tangible common equity; (x) tangible book value; (xi) operating pre-provision net revenue earnings; (xii) operating noninterest income; (xiii) operating noninterest expense; (xiv) tangible assets; and ratios derived therefrom, in its analysis of the company's performance. Operating revenue includes the earnings from net interest income and operating noninterest income (Non-GAAP). Operating earnings excludes the following from net income: securities gains and losses, merger related and restructuring expenses, 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 shareholders’ 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 exclude 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-provision, net-revenue 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. 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. Tangible assets excludes goodwill and other intangibles from total assets. 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.

These estimates of changes in SmartFinancial’s net interest income require us to make certain assumptions including loan and mortgage-related investment prepayment speeds, reinvestment rate, deposit maturities and decay rates. These assumptions are inherently uncertain and, as a result, we cannot precisely predict the impact of changes in interest rates on net interest income. Although our analysis provides an indication of our interest rate risk exposure at a particular point in time, such estimates are not intended to, and do not, provide a precise forecast of the effect of changes in market interest rates and will differ from actual results $2.0 Billion Fixed Rate Loans $1.4 Billion Variable Rate Loans • $829 Million Short-Term Variable Rate (Resetting within 1 - 3 Months) • $626 Million Long-Term Variable Rate (Resets > 3 Months) $ in Millions, unless otherwise indicated $ in Thousands, unless otherwise indicated
