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 recently completed acquisition of Sandy Spring Bancorp, Inc. (“Sandy Spring” or “SASR”) and expectations with regard to the benefits of the Sandy Spring acquisition, including anticipated accretion to earnings per share, the tangible book value earn-back period and other operating and return metrics; our business, financial and operating results, including our deposit base and funding; the impact of future economic conditions, anticipated changes in the interest rate environment and the related impacts on our net interest margin, changes in economic conditions; management’s beliefs regarding our liquidity, capital resources, asset quality, CRE loan portfolio and our customer relationships; 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 “2025 Financial Outlook (inclusive of Sandy Spring beginning April 1st)”, “Financially Compelling Transaction” and “Updates on Key Transaction Metrics”. 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 BanksharesCorporation (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 change 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, including us, to attract and retain depositors and to borrow or raise capital; • legislative or regulatory changes and requirements, including as part of the regulatory reform agenda of the Trump administration, 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, and slowdowns in economic growth; • the diversion of management’s attention from ongoing business operations and opportunities due to our recent acquisition of Sandy Spring; • the impact of purchase accounting with respect to the Sandy Spring acquisition, or 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 our acquisition activity, including our acquisitions of Sandy Spring and American National, 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, or with respect to our acquisition of Sandy Spring, as a result of the impact of, or problems arising from, the integration of the two companies; • the integration of the business and operations of Sandy Spring may take longer or be more costly than anticipated; • potential adverse reactions or changes to business or employee relationships, including those resulting from our acquisitions of Sandy Spring and American National; • monetary, fiscal and regulatory policies of the U.S. government, including 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 identify, 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 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 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, 2024, 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 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 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.

4 PRO FORMA AND MARKET AND INDUSTRY DATA Pro Forma Data Neither Atlantic Union’s nor Sandy Spring’s independent registered public accounting firms have studied, reviewed or performed any procedures with respect to the pro forma or pro forma forward-looking financial data for the purpose of inclusion in this presentation, and, accordingly, neither have expressed an opinion or provided any form of assurance with respect thereto for the purpose of this presentation. The pro forma combined data of Atlantic Union and Sandy Spring is as of March 31, 2025, and is based on the GAAP results of Atlantic Union and Sandy Spring for the applicable periods without adjustments, except where specifically noted. The pro forma combined data included in this presentation does not reflect any purchase accounting adjustments. All pro forma data should be reviewed in connection with the historical information of Atlantic Union and Sandy Spring, as applicable. These pro forma and pro forma forward-looking financial data are for illustrative purposes only and should not be relied on as necessarily being indicative of future results. The assumptions and estimates underlying the pro forma and pro forma forward-looking financial data are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the prospective financial information, including those in the “Forward-Looking Statements” disclaimer on slide 2 of this presentation. Pro forma and pro forma forward-looking financial data is inherently uncertain due to a number of factors outside of Atlantic Union’s and Sandy Spring’s control. Accordingly, there can be no assurance that the pro forma combined information, pro forma forward-looking financial data or prospective results are indicative of future performance of the combined company after the acquisition of Sandy Spring that consummated on April 1, 2025 or that actual results will not differ materially from those presented in the pro forma and pro forma forward-looking financial data. Inclusion of pro forma and pro forma financial data in this presentation should not be regarded as a representation by any person that the results contained in the prospective financial information will be achieved. Further, neither the pro forma nor the pro forma forward-looking financial data has been prepared in accordance with Article 11 of Regulation S-X, and, therefore, does not reflect any of the adjustments that would be required thereby. 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 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.

For non-GAAP financial measures, see reconciliation to most directly comparable GAAP measures in “Appendix – Reconciliation of Non-GAAP Disclosures” Note: all tables presented dollars in thousands, except per share amounts Q1 2025 FINANCIAL PERFORMANCE AT-A-GLANCE Reported net income available to common shareholders for the first quarter of 2025 was $46.9 million or $0.52 per diluted share, down $7.9 million or $0.08 per diluted share compared to the prior quarter, primarily driven by the net impact of the following items: • A decrease in noninterest income, primarily driven by a $2.7 million decrease in loan-related interest rate swap fees due to seasonally lower transaction volumes and a $2.5 million decrease in other operating income primarily due to a decline in equity method investment income and lower gains on the sale of lease equipment; • An increase in noninterest expense, primarily driven by a $4.1 million increase in salaries and benefits expense due primarily to seasonal increases of $4.7 million in payroll taxes and 401(k) contribution expenses, a $1.3 million increase in other expenses primarily driven by OREO-related gains recognized in the prior quarter, a $1.0 million increase in franchise and other taxes, a $805,000 increase in technology and data processing expense primarily driven by expense related to an upgrade to the consumer online banking system, and a $616,000 increase in occupancy expenses primarily driven by seasonal winter weather-related expenses. These increases were partially offset by a $2.1 million decrease in merger-related costs and a $666,000 decrease in professional service fees; • Partially offset by a $916,000 increase in net interest income due primarily to the impact of lower deposit costs, driven by the decrease in the federal funds rate, reflecting the full quarter impact of the Federal Reserve lowering rates 100 basis points between September and December in 2024. This was partially offset by a decrease in interest income on loans held for investment due to lower loan yields primarily driven by the impact of interest rate cuts on our variable loan rate portfolio, as well as the lower day count in the first quarter. Adjusted operating earnings available to common shareholders1 decreased $9.8 million to $51.6 million for the first quarter compared to the prior quarter, primarily driven by the net impact of the following items: • An increase in adjusted noninterest expense1 , as described above excluding merger-related costs; • A decrease in adjusted operating noninterest income1 , as described above; • Partially offset by an increase in net interest income, as described above.

41 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 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 our underlying performance or show the potential effects of accumulated other comprehensive income or unrealized losses on held to maturity securities on our capital.

42 RECONCILIATION OF NON-GAAP DISCLOSURES Adjusted operating measures exclude, as applicable, merger-related costs, and (loss) 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 amortization of intangible assets, merger-related costs, and (loss) gain on sale of securities. 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.

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.

In addition to these regulatory capital ratios, the Company adjusts certain regulatory capital ratios to include the impacts of AOCI, which the Company has elected to exclude from regulatory capital ratios under applicable regulations, and net unrealized losses on HTM securities, assuming that those unrealized losses were realized at the end of the period, as applicable. The Company believes that each of these ratios help investors to assess the Company's regulatory capital levels and capital adequacy.

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 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. Adjusted operating measures exclude, as applicable, merger-related costs, (loss) gain on sale of securities, and amortization of intangible assets. The Company believes these non-GAAP adjusted measures provide investors with important information about the continuing economic results of the Company’s operations.

47 RECONCILIATION OF NON-GAAP DISCLOSURES Pre-tax pre-provision adjusted earnings excludes, as applicable, the provision for credit losses, which can fluctuate significantly from period-to-period under the CECL methodology, income tax expense, merger-related costs, and (loss) gain on sale of securities. The Company believes this adjusted measure provides investors with important information about the continuing economic results of the Company’s operations.
