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 regarding our strategic expansion into North Carolina, including our expectations regarding new branch openings; statements regarding our investments in strategic technology initiatives; statements regarding our business, financial and operating results, including our deposit base and funding; the impact of changes in economic conditions, the interest rate environment, economic, fiscal or trade policy and the potential related impacts on our business and loan demand; management’s beliefs regarding our liquidity, capital resources, asset quality, CRE loan portfolio and our customer relationships; statements regarding our strategy, statements that include other projections, predictions, expectations, or beliefs about future events or results or otherwise are not statements of historical fact, and statements on the slides entitled “Highlights”, “The Next Phase – Harnessing Organic Power” and “2026 Financial Outlook”. 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,” “seek to,” “potential,” “continue,” “confidence,” or words of similar meaning or other statements concerning opinions or judgment of Atlantic Union Bankshares Corporation (the “Company,” “AUB,” “we,” “us” or “our”) and 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; • economic conditions, including inflation and recessionary conditions and their related impacts on economic growth and customer and client behavior; • U.S. and global trade policies and tensions, including changes in, or the imposition of, tariffs and/or trade barriers and the economic impacts, volatility and uncertainty resulting therefrom, and geopolitical instability; • volatility in the financial services sector, including failures or rumors of failures of other depository institutions, along with actions taken by governmental agencies to address such turmoil, and the effects on the ability of depository institutions, including us, to attract and retain depositors and to borrow or raise capital; • legislative or regulatory changes and requirements, including changes in federal state or local tax laws and changes impacting the rulemaking, supervision, examination and enforcement priorities of the federal banking agencies; • 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, U.S. fiscal debt, budget and tax matters, U.S. government shutdowns, and slowdowns in economic growth; • the possibility that the anticipated benefits of our acquisition activity, including anticipated cost savings and strategic gains, are not realized when expected or at all, including 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; • our ability to identify, recruit and retain key employees • monetary, fiscal and regulatory 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 in these portfolios; • 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; • 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; • emerging issues related to the development and use of artificial intelligence that could give rise to legal or regulatory action or increase the risk of a cybersecurity attack or the probability that such an attack would be successful; • 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 consideration; • 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 macroeconomic conditions, 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; • 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, 2025, 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 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 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 because 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 our financial statements, and should not be considered in isolation or as a substitute for comparable measures calculated in accordance with GAAP. In addition, our non-GAAP financial measures may not be comparable to non-GAAP financial measures of other companies. We use the non-GAAP financial measures discussed herein in our analysis of our performance. Our 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 our underlying performance, or show the potential effects of accumulated other comprehensive income (or AOCI) or unrealized losses on securities on our 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, we are 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. Market and Industry Data Unless otherwise indicated, market data and certain industry forecast data used in this presentation were obtained from internal reports, where appropriate, as well as third party sources and other publicly available information. Data regarding the industries and markets in which the Company competes, its market position and market share within these industries are inherently imprecise and are subject to significant business, economic and competitive uncertainties beyond the Company's control. In addition, assumptions and estimates of the Company and its industries' future performance are necessarily subject to a high degree of uncertainty and risk due to a variety of factors. These and other factors could cause future performance to differ materially from assumptions and estimates.

Disciplined execution Delivering on the promises made to our stakeholders.

10 Q3 2026 Highlights Reported net income available to common shareholders decreased 15.4% from the prior quarter driven by: • A decrease in noninterest income, primarily driven by a $32.3 million pre-tax gain on the sale of the Company’s equity interest in Bearing Insurance Group, LLC (“Bearing Insurance”) recognized in the prior quarter; • An increase in noninterest expense, primarily driven by a $2.7 million pre-tax loss on debt extinguishment; • Partially offset by a decrease in provision for credit losses primarily reflecting lower reserve requirements associated with a modest decline in the allowance coverage ratio, as well as slower loan growth relative to the second quarter of 2026; • A decrease in income tax expense associated with lower pre-tax income. Adjusted operating earnings available to common shareholders1 increased 1.2% from the prior quarter primarily due to: • A decrease in provision for credit losses, as described above; • Partially offset by a decrease in adjusted noninterest income1 , primarily due to a $2.0 million decline in loan-related interest rate swap fees, a $1.1 million decrease in mortgage banking income, and a $1.0 million decrease in fiduciary and asset management fees. 1.

Adjusted operating noninterest income1 decreased approximately 5.4% in the third quarter of 2026 compared to the second quarter of 2026 primarily due to: • A $2.0 million decline in loan-related interest rate swap fees driven by lower transaction volumes; • A $1.1 million decrease in mortgage banking income due to lower mortgage origination volumes and lower gain on sale margins; • A $1.0 million decrease in fiduciary and asset management fees.

Adjusted operating noninterest expense1 increased 1.5% in the third quarter of 2026 compared to the second quarter of 2026 primarily due to: • A $2.6 million seasonal increase in marketing and advertising expense; • A $1.7 million increase in salaries and benefits expense, primarily due to an increase in variable incentive compensation expense and additional full-time equivalent employees associated with the Company’s North Carolina expansion; • A $1.5 million increase in technology and data processing expense, primarily reflecting ongoing investments in strategic technology initiatives and related software maintenance costs; • Partially offset by a $3.4 million decrease in other expenses, primarily driven by gains on sales of other real estate owned during the third quarter of 2026.

17 Q3 2026 LOANS AND DEPOSITS • At September 30, 2026, LHFI totaled $29.3 billion, an increase of $623.3 million from the prior quarter primarily due to increases in commercial and industrial, other commercial, and construction and land development loan portfolios. • Average loan yields (FTE)2 decreased 1 basis point to 6.22%. • At September 30, 2026, total deposits were $31.0 billion, an increase of $497.3 million from the prior quarter due to increases in brokered and demand deposits, partially offset by a decrease in interest-bearing customer deposits. • Noninterest-bearing demand deposits accounted for 22% of total deposit balances at the end of the third quarter of 2026, in line with the prior quarter. • The average cost of deposits increased by 7 basis points compared to the prior quarter, resulting from increased costs on customer interest-bearing deposits and higher brokered deposit costs. • At September 30, 2026, the loan to deposit ratio was 94.6%, up from 94.1% in the prior quarter.

31 RECONCILIATION OF NON-GAAP DISCLOSURES We have provided supplemental performance measures determined by methods other than in accordance with GAAP. These non-GAAP financial measures are a supplement to GAAP, which we use to prepare our financial statements, and should not be considered in isolation or as a substitute for comparable measures calculated in accordance with GAAP. In addition, our non-GAAP financial measures may not be comparable to non-GAAP financial measures of other companies. We use the non-GAAP financial measures discussed herein in our analysis of our performance. Management believes that these non-GAAP financial measures provide additional understanding of ongoing operations, enhance the comparability of our 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 our underlying performance or show the potential effects of accumulated other comprehensive income or unrealized losses on held to maturity securities on our capital. Due to the impact of completing the Sandy Spring acquisition in the second quarter of 2025 and the acquisition of American National Bankshares in the second quarter of 2024, we updated our non-GAAP operating measures beginning in the second quarter of 2025 to exclude the CECL Day 1 non-PCD loans and RUC provision expense. The CECL Day 1 non-PCD loans and RUC provision expense is comprised of the initial provision expense on non-PCD loans, which represents the CECL “double count” of the non-PCD credit mark, and the additional provision for unfunded commitments. The Company does not view the CECL Day 1 non-PCD loans and RUC provision expense as organic costs to run the Company’s business and believes this updated presentation provides investors with additional information to assist in period-to-period and company-to-company comparisons of operating performance, which will aid investors in analyzing the Company’s performance. Prior period non-GAAP operating measures presented in this presentation have been recast to conform to this updated presentation.

32 RECONCILIATION OF NON-GAAP DISCLOSURES Adjusted operating measures exclude or include, as applicable, loss on debt extinguishment, gain on sale of equity interest in Bearing Insurance, and gain on sale of securities. The Company believes these non-GAAP adjusted measures provide investors with important information about the continuing economic results of the Company’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 the 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 loss on debt extinguishment, amortization of intangible assets, gain on sale of securities, and gain on sale of equity interest in Bearing Insurance. This measure is similar to the measure used by the Company when analyzing corporate performance and is also similar to the measure used for incentive compensation. The Company believes this adjusted measure provides investors with important information about the continuing economic results of the Company’s operations.

34 RECONCILIATION OF NON-GAAP DISCLOSURES The Company believes net interest income (FTE), total revenue (FTE), and total adjusted revenue (FTE), which are used in computing net interest margin (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 the 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, loss on debt extinguishment, losses related to balance sheet repositioning (principally composed of gains and losses on debt extinguishment), merger-related costs, FDIC special assessments, strategic cost savings 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), legal reserves associated with our previously disclosed settlement with the CFPB, strategic branch closing and facility consolidation costs (principally composed of real estate, leases and other asset write downs, as well as severance and expense reduction initiatives), gain (loss) on sale of securities, gain on sale-leaseback transaction, gain on sale of DHFB, gain on CRE loan sale, gain on sale of equity interest in CSP, gain on sale of equity interest in Bearing Insurance, and gain on sale of Visa, Inc. Class B common stock. This measure is similar to the measure used by the Company when analyzing corporate performance and is also similar to the measure used for incentive compensation. The Company believes this adjusted measure provides investors with important information about the continuing economic results of the Company’s operations.

35 RECONCILIATION OF NON-GAAP DISCLOSURES The Company believes net interest income (FTE), interest income (FTE), investment income (FTE), total revenue (FTE), earning asset income (FTE), total adjusted revenue (FTE), which are used in computing net interest margin (FTE), core net interest margin (FTE), loan yield (FTE), investment yield (FTE), earning asset yield (FTE), efficiency ratio (FTE) and adjusted operating efficiency ratio (FTE), provide valuable additional insight into the net interest margin, loan yield, investment yield, earning asset yield, 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 the 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.

36 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.
