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 "Q4 2023 Highlights and FY 2023 Highlights,“ “Loan and Deposit Betas,” and “Financial Outlook,” statements regarding our strategic priorities, liquidity and capital management strategies, expectations related to our business, financial, and operating results, including our deposit base and funding, the impact of changes in economic conditions, the impact of our cost saving measures, our securities portfolio restructuring, or changes in asset quality, and statements that include, other projections, predictions, expectations, or beliefs about future events or results, including our ability to meet our top tier financial targets, 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, achievements, or trends to be materially different from those expressed or implied by such forward-looking statements. Such 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,” “should,” or words of similar meaning or other statements concerning opinions or judgments of our management about future events. Although we believe that our expectations with respect to forward-looking statements are based on 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, such as bank failures, responsive measures to mitigate and manage such developments, related supervisory and regulatory actions and costs, and related impacts on customer behavior; • the sufficiency of liquidity; • 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; • our failure to close our proposed merger with American National Bankshares Inc. (“American National”) when expected or at all because required regulatory approvals and other conditions to closing are not received or satisfied on a timely basis or at all, and the risk that any regulatory approvals may result in the imposition of conditions that could adversely affect the combined company or the expected benefits of the merger; • the occurrence of any event, change or circumstance that could give rise to the right of either party to terminate the merger agreement between the Company and American National; • any change in the purchase accounting assumptions used regarding the American National assets acquired and liabilities assumed to determine the fair value and credit marks, particularly in light of the current interest rate environment; • the risks that the anticipated benefits of the proposed merger, including cost savings and strategic gains, are not realized when expected or at all; • the proposed merger may be more expensive or take longer to complete than anticipated, including as a result of unexpected factors or events, and may divert management’s attention from ongoing business operations and opportunities; • potential adverse reactions or changes to business or employee relationships, including those resulting from the announcement or completion of the proposed merger; • government monetary and fiscal policies, including policies of the U.S. 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 inflation, changing interest rates, or other factors; • our liquidity and capital positions; • 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, 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; • legislative or regulatory changes and requirements; • 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; • the effects of changes in federal, state or local tax laws and regulations; • 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, 2022, Part II, Item 1A.

27 Reconciliation of Non-GAAP Disclosures The Company has provided supplemental performance measures on a tax-equivalent, tangible, operating, adjusted, or pre-tax pre-provision basis. 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, 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), merger -related costs, a legal reserve associated with our previously disclosed settlement with the CFPB, a FDIC special assessment, 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), gain (loss) on sale of securities, gain on sale -leaseback transaction, and gain on sale of Dixon, Hubard, Feinour & Brown, Inc. ("DHFB"). The Company believes these non -GAAP adjusted measures provide investors with important information about the continuing economic results of the organization’s operations. The Company believes net interest income (FTE), total revenue (FTE), and total adjusted revenue (FTE), which are used in computing net interest margin (FTE), efficiency ratio (FTE) and adjusted operating efficiency ratio (FTE), provide valuable additional insight into the net interest margin and the efficiency ratio by adjusting for differences in tax treatment of interest income sources. The entire FTE adjustment is attributable to interest income on earning assets, which is used in computing yield on earning assets. Interest expense and the related cost of interest -bearing liabilities and cost of funds ratios are not affected by the FTE components. The adjusted operating efficiency ratio (FTE) excludes, as applicable, the amortization of intangible assets, strategic cost saving initiatives, merger -related costs, a legal reserve associated with our previously disclosed settlement with the CFPB, a FDIC special assessment, strategic branch closing and related facility consolidation costs, gain (loss) on sale of securities, gain on sale -leaseback transaction, and gain on sale of DHFB. This measure is similar to the measure utilized by the Company when analyzing corporate performance and is also similar to the measure utilized for incentive compensation. The Company believes this adjusted measure provides investors with important information about the continuing economic results of the organization’s operations. % Change (Dollars in thousands, except per share amounts) 2023 2022 YoY Operating Measures Net Income (GAAP) $ 201,818 $ 234,510 Plus: Strategic cost saving initiatives, net of tax 9,959 - Plus: Merger-related costs, net of tax 2,850 - Plus: Legal reserve, net of tax 6,809 - Plus: FDIC special assessment, net of tax 2,656 - Plus: Strategic branch closing and facility consolidation costs, net of tax - 4,351 Less: Gain (loss) on sale of securities, net of tax (32,381) (2) Less: Gain on sale-leaseback transaction, net of tax 23,367 - Less: Gain on sale of DHFB, net of tax - 7,984 Adjusted operating earnings (non-GAAP) $ 233,106 $ 230,879 Less: Dividends on preferred stock 11,868 11,868 Adjusted operating earnings available to common shareholders (non-GAAP) $ 221,238 $ 219,011 Weighted average common shares outstanding, diluted 74,962,363 74,953,398 EPS available to common shareholders, diluted (GAAP) $ 2.53 $ 2.97 Adjusted operating EPS available to common shareholders (non-GAAP) $ 2.95 $ 2.92 Operating Leverage Ratio and Efficiency Ratio Noninterest expense (GAAP) $ 430,371 $ 403,802 6.58% Less: Amortization of intangible assets 8,781 10,815 Less: Strategic cost saving initiatives 12,607 - Less: Merger-related costs 2,995 - Less: Legal reserve 8,300 - Less: FDIC special assessment 3,362 - Less: Strategic branch closing and facility consolidation costs - 5,508 Adjusted operating noninterest expense (non-GAAP) $ 394,326 $ 387,479 1.77% Noninterest income (GAAP) $ 90,877 $ 118,523 Less: Gain (loss) on sale of securities (40,989) (3) Less: Gain on sale-leaseback transaction 29,579 - Less: Gain on sale of DHFB - 9,082 Adjusted operating noninterest income (non-GAAP) $ 102,287 $ 109,444 Net interest income (GAAP) $ 611,013 $ 584,261 Noninterest income (GAAP) 90,877 118,523 Total revenue (GAAP) $ 701,890 $ 702,784 (0.13%) Net interest income (FTE) (non-GAAP) $ 625,923 $ 599,134 Adjusted operating noninterest income (non-GAAP) 102,287 109,444 Total adjusted revenue (FTE) (non-GAAP) $ 728,210 $ 708,578 2.77% Operating leverage ratio (GAAP) (6.71%) Adjusted operating leverage ratio (non-GAAP) 1.00% Efficiency ratio (GAAP) 61.32% 57.46% Efficiency ratio FTE (non-GAAP) 60.04% 56.27% Adjusted operating efficiency ratio (FTE) (non-GAAP) 54.15% 54.68% ADJUSTED OPERATING EARNINGS, OPERATING LEVERAGE, AND EFFICIENCY RATIO For the years ended December 31,

Class B common stock. The Company believes these non -GAAP adjusted measures provide investors with important information about the continuing economic results of the organization’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. Additionally, the Company believes that return on tangible common equity (ROTCE) is a meaningful supplement to GAAP financial measures and 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.

31 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.
