2 Forward Looking Statements This presentation and statements by our management may constitute “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements are statements that include, without limitation, statements on slides entitled “Q2 2024 Highlights,“ “We are focused on three Strategic Priorities,” and “2024 Financial Outlook,” statements regarding our expectations with regard to the benefits of the American National Bankshares Inc. ("American National") acquisition, our business, financial and operating results, including our deposit base and funding, the impact of future economic conditions, changes in economic conditions, our asset quality, our customer relationships, and statements that include other projections, predictions, expectations, or beliefs about future events or results or otherwise are not statements of historical fact. Such forward-looking statements are based on certain assumptions as of the time they are made, and are inherently subject to known and unknown risks, uncertainties, and other factors, some of which cannot be predicted or quantified, that may cause actual results, performance, or achievements to be materially different from those expressed or implied by such forward-looking statements. Forward-looking statements are often characterized by the use of qualified words (and their derivatives) such as “expect,” “believe,” “estimate,” “plan,” “project,” “anticipate,” “intend,” “will,” “may,” “view,” “opportunity,” “potential,” “continue,” “confidence,” or words of similar meaning or other statements concerning opinions or judgment of the Company and our management about future events. Although we believe that our expectations with respect to forward-looking statements are based upon reasonable assumptions within the bounds of our existing knowledge of our business and operations, there can be no assurance that actual future results, performance, or achievements of, or trends affecting, us will not differ materially from any projected future results, performance, achievements or trends expressed or implied by such forward-looking statements. Actual future results, performance, achievements or trends may differ materially from historical results or those anticipated depending on a variety of factors, including, but not limited to, the effects of or changes in: • market interest rates and their related impacts on macroeconomic conditions, customer and client behavior, our funding costs and our loan and securities portfolios; • inflation and its impacts on economic growth and customer and client behavior; • adverse developments in the financial industry generally, such as bank failures, responsive measures to mitigate and manage such developments, related supervisory and regulatory actions and costs, and related impacts on customer and client behavior; • the sufficiency of liquidity and changes in our capital position; • general economic and financial market conditions, in the United States generally and particularly in the markets in which we operate and which our loans are concentrated, including the effects of declines in real estate values, an increase in unemployment levels and slowdowns in economic growth; • the impact of purchase accounting with respect to our acquisition of American National, or any change in the assumptions used regarding the assets acquired and liabilities assumed to determine the fair value and credit marks; • the possibility that the anticipated benefits of the American National acquisition, including anticipated cost savings and strategic gains, are not realized when expected or at all, including as a result of the impact of, or problems arising from, the recent integration of the two companies or as a result of the strength of the economy, competitive factors in the areas where we do business, or as a result of other unexpected factors or events; • potential adverse reactions or changes to business or employee relationships, including those resulting from the American National acquisition; • monetary and fiscal policies of the U.S. government, including policies of the U.S. Department of the Treasury and the Federal Reserve; • the quality or composition of our loan or investment portfolios and changes therein; • demand for loan products and financial services in our market areas; • our ability to manage our growth or implement our growth strategy; • the effectiveness of expense reduction plans; • the introduction of new lines of business or new products and services; • our ability to recruit and retain key employees; • real estate values in our lending area; • changes in accounting principles, standards, rules, and interpretations, and the related impact on our financial statements; • an insufficient ACL or volatility in the ACL resulting from the CECL methodology, either alone or as that may be affected by changing economic conditions, credit concentrations, inflation, changing interest rates, or other factors; • concentrations of loans secured by real estate, particularly commercial real estate; • the effectiveness of our credit processes and management of our credit risk; • our ability to compete in the market for financial services and increased competition from fintech companies; • technological risks and developments, and cyber threats, attacks, or events; • operational, technological, cultural, regulatory, legal, credit, and other risks associated with the exploration, consummation and integration of potential future acquisitions, whether involving stock or cash considerations; • the potential adverse effects of unusual and infrequently occurring events, such as weather-related disasters, terrorist acts, geopolitical conflicts or public health events (such as pandemics), and of governmental and societal responses thereto; these potential adverse effects may include, without limitation, adverse effects on the ability of our borrowers to satisfy their obligations to us, on the value of collateral securing loans, on the demand for our loans or our other products and services, on supply chains and methods used to distribute products and services, on incidents of cyberattack and fraud, on our liquidity or capital positions, on risks posed by reliance on third-party service providers, on other aspects of our business operations and on financial markets and economic growth; • performance by our counterparties or vendors; • deposit flows; • the availability of financing and the terms thereof; • the level of prepayments on loans and mortgage-backed securities; • the effects of legislative or regulatory changes and requirements, including changes in federal, state or local tax laws; • actual or potential claims, damages, and fines related to litigation or government actions, which may result in, among other things, additional costs, fines, penalties, restrictions on our business activities, reputational harm, or other adverse consequences; • any event or development that would cause us to conclude that there was an impairment of any asset, including intangible assets, such as goodwill; and • other factors, many of which are beyond our control. Please also refer to such other factors as discussed throughout Part I, Item 1A. “Risk Factors” and Part II, Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our Annual Report on Form 10-K for the year ended December 31, 2023, and related disclosures in other filings, which have been filed with the U.S. Securities and Exchange Commission (“SEC”) and are available on the SEC’s website at www.sec.gov. All risk factors and uncertainties described herein and therein should be considered in evaluating forward-looking statements, and all of the forward-looking statements are expressly qualified by the cautionary statements contained or referred to herein and therein. The actual results or developments anticipated may not be realized or, even if substantially realized, they may not have the expected consequences to or effects on the Company or our businesses or operations. Readers are cautioned not to rely too heavily on the forward-looking statements. Forward-looking statements speak only as of the date they are made. We do not intend or assume any obligation to update, revise or clarify any forward-looking statements that may be made from time to time by or on behalf of the Company, whether as a result of new information, future events or otherwise, except as required by law.

3 Additional Information Non-GAAP Financial Measures This presentation contains certain financial information determined by methods other than in accordance with generally accepted accounting principles in the United States (“GAAP”). These non-GAAP financial measures are a supplement to GAAP, which is used to prepare the Company’s financial statements, and should not be considered in isolation or as a substitute for comparable measures calculated in accordance with GAAP. In addition, the Company’s non-GAAP financial measures may not be comparable to non-GAAP financial measures of other companies. The Company uses the non-GAAP financial measures discussed herein in its analysis of the Company’s performance. The Company’s management believes that these non-GAAP financial measures provide additional understanding of ongoing operations, enhance comparability of results of operations with prior periods, show the effects of significant gains and charges in the periods presented without the impact of items or events that may obscure trends in the Company’s underlying performance, or show the potential effects of accumulated other comprehensive income (or AOCI) or unrealized losses on securities on the Company's capital. This presentation also includes certain projections of non-GAAP financial measures. Due to the inherent variability and difficulty associated with making accurate forecasts and projections of information that is excluded from these projected non-GAAP measures, and the fact that some of the excluded information is not currently ascertainable or accessible, the Company is unable to quantify certain amounts that would be required to be included in the most directly comparable projected GAAP financial measures without unreasonable effort. Consequently, no disclosure of projected comparable GAAP measures is included, and no reconciliation of forward-looking non-GAAP financial information is included. Please see “Reconciliation of Non-GAAP Disclosures” at the end of this presentation for a reconciliation to the nearest GAAP financial measure. No Offer or Solicitation This presentation does not constitute an offer to sell or a solicitation of an offer to buy any securities. No offer of securities shall be made except by means of a prospectus meeting the requirements of the Securities Act of 1933, as amended, and no offer to sell or solicitation of an offer to buy shall be made in any jurisdiction in which such offer, solicitation or sale would be unlawful.

27 Reconciliation of Non-GAAP Disclosures The Company has provided supplemental performance measures determined by methods other than in accordance with GAAP. These non-GAAP financial measures are a supplement to GAAP, which is used to prepare the Company’s financial statements, and should not be considered in isolation or as a substitute for comparable measures calculated in accordance with GAAP. In addition, the Company’s non-GAAP financial measures may not be comparable to non-GAAP financial measures of other companies. The Company uses the non-GAAP financial measures discussed herein in its analysis of the Company’s performance. The Company’s management believes that these non-GAAP financial measures provide additional understanding of ongoing operations, enhance comparability of results of operations with prior periods and show the effects of significant gains and charges in the periods presented without the impact of items or events that may obscure trends in the Company’s underlying performance.

28 Reconciliation of Non -GAAP Disclosures Adjusted operating measures exclude, as applicable, merger - related costs, FDIC special assessments, legal reserves associated with our previously disclosed settlement with the CFPB, strategic cost saving initiatives (principally composed of severance charges related to headcount reductions, costs related to modifying certain third party vendor contracts, and charges for exiting certain leases), strategic branch closing and related facility consolidation costs (principally composed of real estate, leases and other assets write downs, as well as severance and expense reduction initiatives), rebranding costs, the net loss related to balance sheet repositioning (principally composed of gains and losses on debt extinguishment), deferred tax asset write -down, (loss) gain on sale of securities, gain on sale -leaseback transaction, gain on sale of Dixon, Hubard, Feinour & Brown, Inc. ("DHFB"), and gain on the sale of Visa, Inc. Class B common stock. The Company believes these non -GAAP adjusted measures provide investors with important information about the continuing economic results of the Company’s operations. Tangible assets and tangible common equity are used in the calculation of certain profitability, capital, and per share ratios. The Company believes tangible assets, tangible common equity and the related ratios are meaningful measures of capital adequacy because they provide a meaningful base for period -to -period and company -to -company comparisons, which the Company believes will assist investors in assessing the capital of the Company and its ability to absorb potential losses. The Company believes tangible common equity is an important indication of its ability to grow organically and through business combinations as well as its ability to pay dividends and to engage in various capital management strategies. The Company believes that return on tangible common equity (“ROTCE”) is a meaningful supplement to GAAP financial measures and is useful to investors because it measures the performance of a business consistently across time without regard to whether components of the business were acquired or developed internally.

30 Reconciliation of Non-GAAP Disclosures Tangible assets and tangible common equity are used in the calculation of certain profitability, capital, and per share ratios. The Company believes tangible assets, tangible common equity and the related ratios are meaningful measures of capital adequacy because they provide a meaningful base for period-to-period and company-to-company comparisons, which the Company believes will assist investors in assessing the capital of the Company and its ability to absorb potential losses. The Company believes tangible common equity is an important indication of its ability to grow organically and through business combinations, as well as its ability to pay dividends and to engage in various capital management strategies. The Company also calculates adjusted tangible common equity to tangible assets ratios to exclude AOCI, which is principally comprised of unrealized losses on AFS securities, and to include the impact of unrealized losses on HTM securities. The Company believes that each of these ratios enables investors to assess the Company's capital levels and capital adequacy without the effects of changes in AOCI, some of which are uncertain and difficult to predict, or assuming that the Company realized all previously unrealized losses on HTM securities at the end of the period, as applicable.
