You should read any such prospectus supplement before making any investment decision. This com munication shall not constitute an offer to sell or the solicitation of an offer to buy these securities, nor shall there be any sale of these securities in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to registrati on or qualification under the securities laws of any such state or jurisdiction. Certain statements in this presentation constitute “forward - looking statements” within the meaning of the Private Securities Lit igation Reform Act of 1995. Examples of forward - looking statements include, but are not limited to, statements regarding the out look and expectations of Atlantic Union and Sandy Spring with respect to the proposed transaction, the strategic benefits and financia l b enefits of the proposed transaction, including the expected impact of the proposed transaction on the combined company’s futu re financial performance (including anticipated accretion to earnings per share, the tangible book value earn - back period and other operating and return metrics), the timing of the closing of the proposed transaction, the ability to successfully integrate the combine d businesses, and statements on the slides entitled "Transaction Highlights," "Transaction Structure & Terms," "Key Transaction Assumptions," "Estimated Pro Forma Financial Metr ics " and "Robust Ongoing Capital Generation.“ Such statements are often characterized by the use of qualified words (and their derivatives) such as “may,” “will,” “anticipate,” “could,” “should,” “would,” “believe,” “contempl ate ,” “expect,” “estimate,” “continue,” “plan,” “project” and “intend,” as well as words of similar meaning or other statements con cerning opinions or judgment of Atlantic Union or Sandy Spring or their management about future events. Forward - looking statements are based on assu mptions as of the time they are made and are subject to risks, uncertainties and other factors that are difficult to predict wit h regard to timing, extent, likelihood and degree of occurrence, which could cause actual results to differ materially from anticipated r esu lts, expressed or implied by such forward - looking statements. Such risks, uncertainties and assumptions, include, among others, the following: • the occurrence of any event, change or other circumstances that could give rise to the right of one or both of the parties to te rminate the merger agreement; • the failure to obtain necessary regulatory approvals (and the risk that such approvals may result in the imposition of condit ion s that could adversely affect the combined company or the expected benefits of the proposed transaction) and the approval by Atl antic Union shareholders and Sandy Spring shareholders, on a timely basis or at all; • the possibility that the anticipated benefits of the proposed transaction, including anticipated cost savings and strategic g ain s, are not realized when expected or at all; • the possibility that the integration of the two companies may be more difficult, time - consuming or costly than expected; • the impact of purchase accounting with respect to the proposed transaction, or any change in the assumptions used regarding t he assets acquired and liabilities assumed to determine their fair value and credit marks; • the outcome of any legal proceedings that may be instituted against Atlantic Union or Sandy Spring; • the possibility that the proposed transaction may be more expensive or take longer to complete than anticipated, including as a result of unexpected factors or events; • diversion of 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 transaction; • changes in Atlantic Union’s or Sandy Spring’s share price before closing; • risks relating to the potential dilutive effect of shares of Atlantic Union’s common stock to be issued in the proposed trans act ion; • other factors that may affect future results of Atlantic Union or Sandy Spring including changes in asset quality and credit ris k; the inability to sustain revenue and earnings growth; changes in interest rates; deposit flows; inflation; customer borrow ing , repayment, investment and deposit practices; the impact, extent and timing of technological changes; capital management activities; and oth er actions of the Federal Reserve Board and legislative and regulatory actions and reforms. Although each of Atlantic Union and Sandy Spring believes that its expectations with respect to forward - looking statements are b ased upon reasonable assumptions within the bounds of its existing knowledge of its business and operations, there can be no ass urance that actual results of Atlantic Union or Sandy Spring will not differ materially from any projected future results expressed or implied by such forward - looking statements. Additional factors that could cause results to differ materially from those describe d above can be found in Atlantic Union’s most recent annual report on Form 10 - K and quarterly reports on Form 10 - Q, and other documents subsequently filed by Atlantic Union with the SEC, and in Sandy Spring’s most recent annual report on Form 10 - K and quarterly reports on Form 10 - Q, and other documents subsequently filed by Sandy Spring with the SEC. The actual results anticipated may not be realized or, e ven if substantially realized, they may not have the expected consequences to or effects on Atlantic Union, Sandy Spring or their r espective businesses or operations. Investors are cautioned not to rely too heavily on any such forward - looking statements. Forward - lookin g statements speak only as of the date they are made and Atlantic Union and Sandy Spring undertake no obligation to update or cl arify these forward - looking statements, whether as a result of new information, future events or otherwise. 2

These 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 pr o 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 “ Caution about Forward - Looking Statements” disclaimer on slide 2 of this presentation .

The Company believes that these non - GAAP measures, when taken together with its financial results presented in accordance with GAAP, provide meaningful supplemental information regarding its operating performance and facilitate internal comparisons of its historical operating performance on a more consistent basis.
