SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	Mar. 31, 2021
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The Company Headquartered in Richmond, Virginia, Atlantic Union Bankshares Corporation (Nasdaq: AUB) is the holding company for Atlantic Union Bank. Atlantic Union Bank has 129 branches and approximately 150 ATMs located throughout Virginia, and in portions of Maryland and North Carolina. Atlantic Union Bank Wealth Management is a brand name used by Atlantic Union Bank and certain affiliates when providing trust, wealth management, private banking, and investment advisory products and services. Certain non-bank affiliates of Atlantic Union Bank include: Old Dominion Capital Management, Inc., and its subsidiary, Outfitter Advisors, Ltd., and Dixon, Hubard, Feinour, & Brown, Inc., which provide investment advisory services, Atlantic Union Financial Consultants, LLC, which provides brokerage services; and Union Insurance Group, LLC, which offers various lines of insurance products. Effective March 1, 2021, Middleburg Financial, the Bank’s wealth management division was rebranded to Atlantic Union Bank Wealth Management, and Middleburg Investment Services, LLC changed its name to Atlantic Union Financial Consultants, LLC. The unaudited consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. The unaudited consolidated financial statements have been prepared in accordance with U.S. GAAP for interim financial information and follow general practice within the banking industry. Accordingly, the unaudited consolidated financial statements do not include all the information and footnotes required by U.S. GAAP for complete financial statements; however, in the opinion of management all adjustments necessary for a fair presentation of the results of the interim periods presented have been made. The results of operations for the interim periods are not necessarily indicative of the results that may be expected for the full year or any other period. The unaudited consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto included in the Company’s 2020 Form 10-K. Certain prior period amounts have been reclassified to conform to current period presentation. Adoption of New Accounting Standards In March 2020, the FASB issued Topic 848. This guidance provides temporary, optional guidance to ease the potential burden in accounting for reference rate reform associated with the LIBOR transition. LIBOR and other interbank offered rates are widely used benchmark or reference rates that have been used in the valuation of loans, derivatives, and other financial contracts. Global capital markets are going to be required to move away from LIBOR and other interbank offered rates and toward rates that are more observable or transaction based and less susceptible to manipulation. Topic 848 provides optional expedients and exceptions for applying GAAP to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. Topic 848 is intended to help stakeholders during the global market-wide reference rate transition period. The amendments are effective as of March 12, 2020 through December 31, 2022 and can be adopted at an instrument level. As of March 31, 2021, the Company utilized the expedient to assert probability of the hedged interest, regardless of any expected modification in terms related to reference rate reform for the newly executed cash flow hedges. The Company expects to incorporate other components of Topic 848 at a later date. This amendment does not have a material impact on the consolidated financial statements. On January 1, 2021, the Company adopted Topic 740. This guidance was issued to simplify accounting for income taxes by removing specific technical exceptions that often produce information difficult for users of financial statements to understand. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. The Company’s adoption of Topic 740 did not have a material impact on the consolidated financial statements. Cash and Cash Equivalents For purposes of reporting cash flows, the Company defines cash and cash equivalents as cash, cash due from banks, interest-bearing deposits in other banks, money market investments, other interest-bearing deposits, and federal funds sold. Restricted cash is disclosed in Note 7 “Commitments and Contingencies” and is comprised of cash maintained at various correspondent banks as collateral for the Company’s derivative portfolio and is included in interest-bearing deposits in other banks in the Company’s Consolidated Balance Sheets. In addition, the Company is required to maintain reserve balances with the Federal Reserve Bank based on the type and amount of deposits; however, on March 15, 2020 the Federal Reserve Board announced that reserve requirement ratios would be reduced to zero percent effective March 26, 2020 due to economic conditions, which eliminated the reserve requirement for all depository institutions. Accrued Interest Receivable The Company has elected to exclude accrued interest from the amortized cost basis in its determination of the ALLL, as well as the ACL reserve for securities. Accrued interest receivable totaled $57.4 million and $56.7 million on loans held for investment, $5.1 million and $6.8 million on HTM securities, and $11.7 million and $11.9 million on AFS securities at March 31, 2021 and December 31, 2020, respectfully, and is included in “Other Assets” on the Company’s Consolidated Balance Sheets. The Company’s policy is to write off accrued interest receivable through reversal of interest income when it becomes probable the Company will not be able to collect the accrued interest. For the quarters ended March 31, 2021 and March 31, 2020, accrued interest receivable write offs were not material to the Company’s consolidated financial statements.

As of March 31, 2021, there were $21.3 million, or 12 instances, of individual AFS securities that had been in a continuous loss position for more than 12 months and had an aggregate unrealized loss of $93,000 . As of December 31, 2020, there were $17.6 million, or 15 instances, of individual securities that had been in a continuous loss position for more than 12 months and had an aggregate unrealized loss of $101,000 . The Company has evaluated AFS securities in an unrealized loss position for credit related impairment at March 31, 2021 and December 31, 2020 and concluded no impairment existed based on several factors which included: (1) the majority of these securities are of high credit quality, (2) unrealized losses are primarily the result of market volatility, (3) the contractual terms of the investments do not permit the issuer(s) to settle the securities at a price less than the cost basis of each investment, (4) issuers continue to make timely principal and interest payments, and (5) the Company does not intend to sell any of the investments and the accounting standard of “more likely than not” has not been met for the Company to be required to sell any of the investments before recovery of its amortized cost basis. Additionally, the majority of the Company’s mortgage-backed securities are issued by FNMA, FHLMC, and GNMA and do not have credit risk given the implicit and explicit government guarantees associated with these agencies. In addition, the non-agency mortgage-backed and asset-backed securities generally received a 20% SSFA rating. The following table presents the amortized cost and estimated fair value of AFS securities as of March 31, 2021 and December 31, 2020, by contractual maturity.

Held to Maturity The Company’s HTM investment portfolio primarily consists of highly-rated municipal securities and the estimated credit loss inherent in the portfolio is currently immaterial. The Company’s HTM securities were all current, with no securities past due or on non-accrual at March 31, 2021 and December 31, 2020. The Company reports HTM securities on the Company’s Consolidated Balance Sheets at carrying value. Carrying value is amortized cost, which includes any unamortized unrealized gains and losses recognized in accumulated other comprehensive income prior to reclassifying the securities from AFS securities to HTM securities. Investment securities transferred into the HTM category from the AFS category are recorded at fair value at the date of transfer. The unrealized holding gain or loss at the date of transfer is retained in accumulated other comprehensive income and in the carrying value of the HTM securities. Such unrealized gains or losses are accreted over the remaining life of the security with no impact on future net income. The carrying value, gross unrealized gains and losses, and estimated fair values of HTM securities as of March 31, 2021 are summarized as follows (dollars in thousands): Carrying Gross Unrealized Estimated Value Gains (Losses) Fair Value March 31, 2021 U.S. government and agency securities $ 2,676 $ — $ (31) $ 2,645 Obligations of states and political subdivisions 535,634 62,880 — 598,514 Commercial mortgage-backed securities Agency 5,265 1 (66) 5,200 Non-agency — — — — Total commercial mortgage-backed securities 5,265 1 (66) 5,200 Total held-to-maturity securities $ 543,575 $ 62,881 $ (97) $ 606,359 The carrying value, gross unrealized gains and losses, and estimated fair values of HTM securities as of December 31, 2020 are summarized as follows (dollars in thousands): Carrying Gross Unrealized Estimated Value Gains (Losses) Fair Value December 31, 2020 U.S. government and agency securities $ 2,751 $ — $ (18) $ 2,733 Obligations of states and political subdivisions 536,767 74,978 — 611,745 Commercial mortgage-backed securities Agency 5,333 4 (50) 5,287 Non-agency — — — — Total commercial mortgage-backed securities 5,333 4 (50) 5,287 Total held-to-maturity securities $ 544,851 $ 74,982 $ (68) $ 619,765 Credit Quality Indicators & Allowance for Credit Losses - HTM For HTM securities, the Company evaluates the credit risk of its securities on at least a quarterly basis.

See Note 1 “Summary of Significant Accounting Policies” in the Company’s 2020 Form 10-K for additional information on the Company’s policies for nonaccrual loans. Troubled Debt Restructurings The CARES Act, as amended by the CAA, permits financial institutions to suspend requirements under GAAP for loan modifications to borrowers affected by COVID-19 that would otherwise be characterized as TDRs and suspend any determination related thereto if (i) the loan modification is made between March 1, 2020 and the earlier of January 1, 2022 or 60 days after the end of the COVID-19 emergency declaration and (ii) the applicable loan was not more than 30 days past due as of December 31, 2019. In addition, federal bank regulatory authorities have issued guidance to encourage financial institutions to make loan modifications for borrowers affected by COVID-19 and have assured financial institutions that they will neither receive supervisory criticism for such prudent loan modifications, nor be required by examiners to automatically categorize COVID-19-related loan modifications as TDRs. As of March 31, 2021 and December 31, 2020, the Company had approximately $ 68.1 million and $146.1 million, respectively, in loans still under their modified terms. The Company’s modification program primarily included payment deferrals and interest only modifications. In addition to the above mentioned modifications, as of March 31, 2021 , the Company has TDRs totaling $ 19.7 million with an estimated $ 1.2 million of allowance for those loans for the current period. As of December 31, 2020, the Company had TDRs totaling $20.6 million with an estimated $1.6 million of allowance for those loans. A modification of a loan’s terms constitutes a TDR if the creditor grants a concession that it would not otherwise consider to the borrower for economic or legal reasons related to the borrower’s financial difficulties. All loans that are considered to be TDRs are evaluated for credit losses in accordance with the Company’s ALLL methodology. For the three months ended March 31, 2021 and March 31, 2020, the recorded investment in TDRs prior to modifications was not materially impacted by the modifications.

The Company estimates its ALLL on its loan portfolio on a quarterly basis. The Company models the ALLL using two primary segments, Commercial and Consumer. Within each segment, loan classes are further identified based on similar risk characteristics. The Company has identified the following classes within each segment: ● Commercial : Construction and Land Development, Commercial Real Estate – Owner Occupied, Commercial Real Estate – Non-Owner Occupied, Multifamily Real Estate, Commercial & Industrial, Residential 1-4 Family – Commercial, and Other Commercial ● Consumer : Residentil 1-4 Family – Consumer, Residential 1-4 Family – Revolving, Auto, and Consumer The following tables show the ALLL activity by segment for the three months ended March 31, 2021 and 2020 (dollars in thousands): Three Months Ended March 31, 2021 Commercial Consumer Total Balance at beginning of period $ 117,403 $ 43,137 $ 160,540 Loans charged-off (1,974) (1,667) (3,641) Recoveries credited to allowance 1,606 863 2,469 Provision charged to operations (10,603) (5,854) (16,457) Balance at end of period $ 106,432 $ 36,479 $ 142,911 Three Months Ended March 31, 2020 Commercial Consumer Total Balance at beginning of period $ 30,941 $ 11,353 $ 42,294 Impact of ASC 326 adoption on non-PCD loans 4,432 40,666 45,098 Impact of ASC 326 adoption on PCD loans 1,752 634 2,386 Impact of adopting ASC 326 6,184 41,300 47,484 Loans charged-off (2,968) (4,183) (7,151) Recoveries credited to allowance 1,154 1,006 2,160 Provision charged to operations 42,532 13,724 56,256 Balance at end of period $ 77,843 $ 63,200 $ 141,043 Credit Quality Indicators Credit quality indicators are utilized to help estimate the collectability of each loan class within the Commercial and Consumer segments. For classes of loans within the Commercial segment, the primary credit quality indicator used for evaluating credit quality and estimating the ALLL is risk rating categories of Pass, Watch, Special Mention, Substandard, and Doubtful. For classes of loans within the Consumer segment, the primary credit quality indicator used for evaluating credit quality and estimating the ALLL is delinquency bands of Current, 30-59, 60-89, 90+, and Nonaccrual. While other credit quality indicators are evaluated and analyzed as part of the Company’s credit risk management activities, these indicators are primarily used in estimating the ALLL. The Company evaluates the credit risk of its loan portfolio on at least a quarterly basis. Commercial Loans The Company uses a risk rating system as the primary credit quality indicator for classes of loans within the Commercial segment. The risk rating system on a scale of 0 through 9 is used to determine risk level as used in the calculation of the allowance for credit loss. The risk levels, as described below, do not necessarily follow the regulatory definitions of risk levels with the same name. A general description of the characteristics of the risk levels follows: Pass is determined by the following criteria: ● Risk rated 0 loans have little or no risk and are with General Obligation Municipal Borrowers; ● Risk rated 1 loans have little or no risk and are generally secured by cash or cash equivalents; ● Risk rated 2 loans have minimal risk to well qualified borrowers and no significant questions as to safety; ● Risk rated 3 loans are satisfactory loans with strong borrowers and secondary sources of repayment; ● Risk rated 4 loans are satisfactory loans with borrowers not as strong as risk rated 3 loans and may exhibit a greater degree of financial risk based on the type of business supporting the loan. Watch is determined by the following criteria: ● Risk rated 5 loans are watch loans that warrant more than the normal level of supervision and have the possibility of an event occurring that may weaken the borrower’s ability to repay; Special Mention is determined by the following criteria: ● Risk rated 6 loans have increasing potential weaknesses beyond those at which the loan originally was granted and if not addressed could lead to inadequately protecting the Company’s credit position. Substandard is determined by the following criteria: ● Risk rated 7 loans are substandard loans and are inadequately protected by the current sound worth or paying capacity of the obligor or the collateral pledged; these have well defined weaknesses that jeopardize the liquidation of the debt with the distinct possibility the Company will sustain some loss if the deficiencies are not corrected. Doubtful is determined by the following criteria: ● Risk rated 8 loans are doubtful of collection and the possibility of loss is high but pending specific borrower plans for recovery, its classification as a loss is deferred until its more exact status is determined; ● Risk rated 9 loans are loss loans which are considered uncollectable and of such little value that their continuance as bankable assets is not warranted.

GOODWILL AND INTANGIBLE ASSETS	Mar. 31, 2021
Goodwill and Intangible Assets Disclosure [Abstract]
INTANGIBLE ASSETS	4. GOODWILL AND INTANGIBLE ASSETS The Company’s intangible assets consist of core deposits, goodwill, and other intangibles arising from acquisitions. The Company has determined that core deposit intangibles have finite lives and amortizes them over their estimated useful lives. Core deposit intangibles are being amortized over the period of expected benefit, which ranges from 4 to 10 years , using an accelerated method. Other amortizable intangible assets are being amortized over the period of expected benefit, which ranges from 4 to 10 years , using various methods. The COVID-19 pandemic has disrupted and adversely impacted the economy and created significant volatility in the financial markets. The volatility in the financial markets adversely affected the Company’s expected future cash flows, due to the lower interest rate environment and other factors. The forecasted impact from COVID-19 was included in the Company’s annual goodwill impairment test in the second quarter of 2020, and while the fair value of the reporting unit declined from the prior test, the Company determined that there was no impairment to its goodwill or intangible assets. In the normal course of business, the Company routinely monitors the impact of the changes in the financial markets and includes these assessments in the Company’s goodwill impairment process. The Company analyzed its intangible assets at March 31, 2021 and concluded no impairment existed as of the balance sheet date. Amortization expense of intangibles for the three months ended March 31, 2021 and 2020 totaled $ 3.7 million and $4.4 million, respectively. As of March 31, 2021, the estimated remaining amortization expense of intangibles is as follows for the years ending (dollars in thousands): For the remaining nine months of 2021 $ 10,159 2022 11,490 2023 9,688 2024 7,818 2025 6,221 Thereafter 8,095 Total estimated amortization expense $ 53,471

LEASES

LEASES	3 Months Ended
LEASES	Mar. 31, 2021
Leases [Abstract]
LEASES	5. LEASES The Company enters into both lessor and lessee arrangements and determines if an arrangement is a lease at inception. As both a lessee and lessor, the Company elected the practical expedient permitted under the transition guidance within the standard to account for lease and non-lease components as a single lease component for all asset classes. Lessor Arrangements The Company’s lessor arrangements consist of sales-type and direct financing leases for equipment. Lease payment terms are fixed and are typically payable in monthly installments with terms ranging from 31 months to 125 months . The lease arrangements may contain renewal options and purchase options that allow the lessee to purchase the leased equipment at the end of the lease term. The leases generally do not contain non-lease components. The Company has no material sale leaseback transactions and no lease transactions with related parties. At lease inception the Company estimates the expected residual value of the leased property at the end of the lease term by considering both internal and third-party appraisals. In certain cases, the Company obtains lessee-provided residual value guarantees and third-party RVI to reduce its residual asset risk. At March 31, 2021 and December 31, 2020, the carrying value of residual assets covered by residual value guarantees and RVI was $14.1 million and $14.7 million, respectively. The net investment in sales-type and direct financing leases consists of the carrying amount of the lease receivables plus unguaranteed residual assets, net of unearned income and any deferred selling profit on direct financing leases. The lease receivables include the lessor’s right to receive lease payments and the guaranteed residual asset value the lessor expects to derive from the underlying assets at the end of the lease term. The Company’s net investment in sales-type and direct financing leases are included in Loans Held for Investment (net of deferred fees and costs) on the Company’s Consolidated Balance Sheets. Lease income is recorded within Interest Income on the Company’s Consolidated Statements of Income. There were no significant changes in the balance of the Company’s unguaranteed residual assets for the periods ending March 31, 2021and December 31, 2020. Total net investment in sales-type and direct financing leases consists of the following (dollars in thousands): March 31, 2021 December 31, 2020 Sales-type and direct financing leases: Lease receivables, net of unearned $ 150.0 $ 141.2 Unguaranteed residual values, net of unearned 5.3 4.8 Total net investment in sales-type and direct financing leases $ 155.3 $ 146.0 Lessee Arrangements The Company’s lessee arrangements consist of operating and finance leases; however, the majority of the leases have been classified as non-cancellable operating leases and are primarily for real estate leases with remaining lease terms of up to 25 years . The Company’s real estate lease agreements do not contain residual value guarantees and most agreements do not contain restrictive covenants. The Company does not have any material arrangements where the Company is in a sublease contract. Lessee arrangements with an initial term of 12 months or less are not recorded on the Consolidated Balance Sheets. The ROU Assets and lease liabilities associated with operating and finance leases greater than 12 months are recorded in the Company’s Consolidated Balance Sheets; ROU Assets within Other Assets and lease liabilities within Other Liabilities. ROU Assets represent the Company’s right to use an underlying asset over the course of the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. The initial measurement of lease liabilities and ROU Assets are the same for operating and finance leases. Lease liabilities are recognized at the commencement date based on the present value of the remaining lease payments, discounted using the incremental borrowing rate. As most of the Company’s leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. ROU Assets are recognized at commencement date based on the initial measurement of the lease liability, any lease payments made excluding lease incentives, and any initial direct costs incurred. Most of the Company’s operating leases include one or more options to renew and the Company is reasonably certain to exercise those options. The options to exercise are included in the measurement of the operating ROU Assets and lease liabilities. Lease expense for operating lease payments is recognized on a straight-line basis over the lease term and recorded in Occupancy Expense within noninterest expense on the Company’s Consolidated Statements of Income. Finance lease expenses consist of straight-line amortization expense of the ROU Assets recognized over the lease term and interest expense on the lease liability. Total finance lease expenses for the amortization of the ROU Assets are recorded in Occupancy Expense within noninterest expense on the Company’s Consolidated Statements of Income and interest expense on the finance lease liability is recorded in Interest Expense on Long-Term Borrowings within total interest expense on the Company’s Consolidated Statements of Income. As of March 31, 2021 and December 31, 2020, the Company had no sales leaseback transactions or leases that have no t yet commenced that create significant rights and obligations.

COMMITMENTS AND CONTINGENCIES	Mar. 31, 2021
Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	7. COMMITMENTS AND CONTINGENCIES Litigation Matters In the ordinary course of its operations, the Company and its subsidiaries are parties to various legal proceedings. Based on the information presently available, and after consultation with legal counsel, management believes that the ultimate outcome in such proceedings, in the aggregate, will not have a material adverse effect on the business, financial condition, or results of operations of the Company. Financial Instruments with Off-Balance Sheet Risk The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers and to reduce its own exposure to fluctuations in interest rates. These financial instruments include commitments to extend credit and letters of credit. These instruments involve elements of credit and interest rate risk in excess of the amount recognized on the Company’s Consolidated Balance Sheets. The contractual amounts of these instruments reflect the extent of the Company’s involvement in particular classes of financial instruments. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instruments for commitments to extend credit and letters of credit written is represented by the contractual amount of these instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. Unless noted otherwise, the Company does not require collateral or other security to support off-balance sheet financial instruments with credit risk. The Company considers credit losses related to off-balance sheet commitments by undergoing a similar process in evaluating losses for loans that are carried on the balance sheet. The Company considers historical loss and funding information, current and future economic conditions, risk ratings, and past due status among other factors in the consideration of expected credit losses in the Company’s off-balance sheet commitments to extend credit. The Company also records an indemnification reserve that includes balances relating to mortgage loans previously sold based on historical statistics and loss rates. As of March 31, 2021 and December 31, 2020, the Company’s reserves for unfunded commitment and indemnification were $13.6 million and $ 10.8 million, respectively. Commitments to extend credit are agreements to lend to customers as long as there are no violations of any conditions established in the contracts. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Because many of the commitments may expire without being completely drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Letters of credit are conditional commitments issued by the Company to guarantee the performance of customers to third parties.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES	8. DERIVATIVES The Company is exposed to economic risks arising from its business operations and uses derivatives primarily to manage risk associated with changing interest rates, and to assist customers with their risk management objectives. The Company designates certain derivatives as hedging instruments in a qualifying hedge accounting relationship (cash flow or fair value hedge). The remaining are classified as free-standing derivatives consisting of customer accommodation loan swaps and interest rate lock commitments that do not qualify for hedge accounting. Derivatives Counterparty Credit Risk Derivative instruments contain an element of credit risk that arises from the potential failure of a counterparty to perform according to the terms of the contract. The Company’s exposure to derivative counterparty credit risk, at any point in time, is equal to the amount reported as a derivative asset on the Company’s Consolidated Balance Sheets, assuming no recoveries of underlying collateral. The Company clears certain OTC derivatives with central clearinghouses through FCMs due to applicable regulatory requirement, which reduces the Company’s counterparty risk. The Company also enters into legally enforceable master netting agreements and collateral agreements, where possible, with certain derivative counterparties to mitigate the risk of default on a bilateral basis. These bilateral agreements typically provide the right to offset exposures and require one counterparty to post collateral on derivative instruments in a net liability position to the other counterparty. Cash Flow Hedges The Company designates derivatives as cash flow hedges when they are used to manage exposure to variability in cash flows related to forecasted transactions on variable rate financial instruments. The Company uses interest rate swap agreements as part of its hedging strategy by exchanging a notional amount, equal to the principal amount of the borrowings or commercial loans, for fixed-rate interest based on benchmarked interest rates. The original terms and conditions of the interest rate swaps vary and range in length. Amounts receivable or payable are recognized as accrued under the terms of the agreements. All swaps were entered into with counterparties that met the Company’s credit standards, and the agreements contain collateral provisions protecting the at-risk party. The Company concluded that the credit risk inherent in the contract is not significant. For derivatives designated and qualifying as cash flow hedges, ineffectiveness is not measured or separately disclosed. Rather, as long as the hedging relationship continues to qualify for hedge accounting, the entire change in the fair value of the hedging instrument is recorded in OCI and recognized in earnings as the hedged transaction affects earnings. Derivative amounts affecting earnings are recognized consistent with the classification of the hedged item. During the quarter ended March 31, 2021, the Company executed two interest rate swaps designated and qualifying as cash flow hedges of the Company’s forecasted variable interest receipts on variable rate loans due to changes in the LIBOR rate with a total notional amount of $200 million. For each agreement, the Company receives interest at a fixed rate and pays at a variable rate. During the quarter ended March 31, 2020, the Company terminated interest rate swaps designated as cash flow hedges prior to their respective maturity dates resulting in net losses of approximately $1.8 million, which resulted in the losses being recognized immediately in earnings as the forecasted transactions will not occur. The Company did not have any derivatives designated as cash flow hedges outstanding at December 31, 2020. Fair Value Hedge Derivatives are designated as fair value hedges when they are used to manage exposure to changes in the fair value of certain financial assets and liabilities, referred to as the hedged items, which fluctuate in value as a result of movements in interest rates. Loans: During the normal course of business, the Company enters into swap agreements to convert certain long-term fixed-rate loans to floating rates to hedge the Company’s exposure to interest rate risk. The Company pays a fixed interest rate to the counterparty and receives a floating rate from the same counterparty calculated on the aggregate notional amount. At March 31, 2021 and December 31, 2020, the aggregate notional amount of the related hedged items for certain long-term fixed rate loans totaled $121.3 million and $74.7 million, respectively, and the fair value of the swaps associated with the derivative related to hedged items was an unrealized loss of $672,000 and $5.1 million, respectively. AFS Securities: The Company has entered into a swap agreement to hedge the interest rate risk on a portion of its fixed rate available for sale securities. At March 31, 2021 and December 31, 20 20 , the aggregate notional amount of the related hedged items of the AFS securities totaled $50 million and the fair value of the swaps associated with the derivative related to hedged items was an unrealized loss of $5.1 million and $7.3 million, respectively. The Company applies hedge accounting in accordance with ASC 815, Derivatives and Hedging , and the fair value hedge and the underlying hedged item, attributable to the risk being hedged, are recorded at fair value with unrealized gains and losses being recorded on the Company’s Consolidated Statements of Income. The Company assesses the effectiveness of each hedging relationship by comparing the changes in fair value or cash flows on the derivative hedging instrument with the changes in fair value or cash flows on the designated hedged item or transactions for the risk being hedged. If a hedging relationship ceases to qualify for hedge accounting, the relationship is discontinued and future changes in the fair value of the derivative instrument are recognized in current period earnings. For a discontinued or terminated fair value hedging relationship, all remaining basis adjustments to the carrying amount of the hedged item are amortized to interest income or expense over the remaining life of the hedged item consistent with the amortization of other discounts or premiums. Previous balances deferred in AOCI from discontinued or terminated cash flow hedges are reclassified to interest income or expense as the hedged transactions affect earnings or over the originally specified term of the hedging relationship. The Company’s hedges continue to be highly effective and had no material impact on the Consolidated Statements of Income. Loan Swaps During the normal course of business, the Company offers interest rate swap loan relationships (“loan swaps”) to its borrowers to help meet their financing needs. Upon entering into the loan swaps, the Company enters into offsetting positions with a third party in order to minimize interest rate risk. These back-to-back loan swaps qualify as financial derivatives with fair values as reported in “Other Assets” and “Other Liabilities” on the Company’s Consolidated Balance Sheets. The following table summarizes key elements of the Company’s derivative instruments as of March 31, 2021 and December 31, 20 20 , segregated by derivatives that are considered accounting hedges and those that are not (dollars in thousands): March 31, 2021 December 31, 2020 Derivative (2) Derivative (2) Notional or Notional or Contractual Contractual Amount (1) Assets Liabilities Amount (1) Assets Liabilities Derivatives designated as accounting hedges: Interest rate contracts: Cash flow hedges $ 200,000 $ — $ 1,808 $ — $ — $ — Fair value hedges 171,323 2,139 7,949 124,726 — 12,483 Derivatives not designated as accounting hedges: Loan Swaps : Pay fixed - receive floating interest rate swaps 2,393,919 22,420 84,030 2,356,453 212 163,148 Pay floating - receive fixed interest rate swaps 2,393,919 84,030 22,420 2,356,453 163,148 212 (1) Notional amounts are not recorded on the Company’s Consolidated Balance Sheets and are generally used only as a basis on which interest and other payments are determined.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS	Mar. 31, 2021
Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	10. FAIR VALUE MEASUREMENTS The Company follows ASC 820 to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. ASC 820 clarifies that fair value of certain assets and liabilities is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between willing market participants. ASC 820 specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. The three levels of the fair value hierarchy under ASC 820 based on these two types of inputs are as follows: Level 1 Valuation is based on quoted prices in active markets for identical assets and liabilities. Level 2 Valuation is based on observable inputs including quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar assets and liabilities in less active markets, and model-based valuation techniques for which significant assumptions can be derived primarily from or corroborated by observable data in the markets. Level 3 Valuation is based on model-based techniques that use one or more significant inputs or assumptions that are unobservable in the market. These unobservable inputs reflect the Company’s assumptions about what market participants would use and information that is reasonably available under the circumstances without undue cost and effort. Assets and Liabilities Measured at Fair Value on a Recurring Basis The following describes the valuation techniques used by the Company to measure certain financial assets and liabilities recorded at fair value on a recurring basis in the financial statements. Derivative instruments As discussed in Note 8 “Derivatives”, the Company records derivative instruments at fair value on a recurring basis. The Company utilizes derivative instruments as part of the management of interest rate risk to modify the re-pricing characteristics of certain portions of the Company’s interest-bearing assets and liabilities. The Company has contracted with a third-party vendor to provide valuations for derivatives using standard valuation techniques and therefore classifies such valuations as Level 2. Third party valuations are validated by the Company using Bloomberg Valuation Service’s derivative pricing functions. No material differences were identified during the validation as of March 31, 2021 and December 31, 2020. The Company has considered counterparty credit risk in the valuation of its derivative assets and has considered its own credit risk in the valuation of its derivative liabilities. Mortgage banking derivatives as of March 31, 2021 and December 31, 2020 did not have a material impact on the Company’s Consolidated Financial Statements. AFS Securities AFS securities are recorded at fair value on a recurring basis. Fair value measurement is based upon quoted market prices, when available (Level 1). If quoted market prices are not available, fair values are measured utilizing independent valuation techniques of identical or similar securities for which significant assumptions are derived primarily from or corroborated by observable market data (Level 2). If the inputs used to provide the evaluation for certain securities are unobservable and/or there is little, if any, market activity, then the security would fall to the lowest level of the hierarchy (Level 3). The Company’s investment portfolio is primarily valued using fair value measurements that are considered to be Level 2. The Company has contracted with a third-party portfolio accounting service vendor for valuation of its securities portfolio. The vendor’s primary source for security valuation is ICE Data Services, which evaluates securities based on market data. ICE Data Services utilizes evaluated pricing models that vary by asset class and include available trade, bid, and other market information. Generally, the methodology includes broker quotes, proprietary models, vast descriptive terms and conditions databases, as well as extensive quality control programs. The vendor utilizes proprietary valuation matrices for valuing all municipals securities. The initial curves for determining the price, movement, and yield relationships within the municipal matrices are derived from industry benchmark curves or sourced from a municipal trading desk. The securities are further broken down according to issuer, credit support, state of issuance, and rating to incorporate additional spreads to the industry benchmark curves. The Company primarily uses Bloomberg Valuation Service, an independent information source that draws on quantitative models and market data contributed from over 4,000 market participants, to validate third party valuations. Any material differences between valuation sources are researched by further analyzing the various inputs that are utilized by each pricing source. No material differences were identified during the validation as of March 31, 2021 and December 31, 2020. The carrying value of restricted FRB and FHLB stock approximates fair value based on the redemption provisions of each entity and is therefore excluded from the table below. Loans Held for Sale Loans held for sale are carried at fair value. These loans currently consist of residential loans originated for sale in the secondary market. Fair value is based on the price secondary markets are currently offering for similar loans using observable market data which is not materially different than cost due to the short duration between origination and sale (Level 2). Gains and losses on the sale of loans are recorded in current period earnings as a component of "Mortgage banking income" on the Company’s Consolidated Statements of Income. The following table presents the balances of financial assets and liabilities measured at fair value on a recurring basis at March 31, 2021 and December 31, 2020 (dollars in thousands): Fair Value Measurements at March 31, 2021 using Significant Quoted Prices in Other Significant Active Markets for Observable Unobservable Identical Assets Inputs Inputs Level 1 Level 2 Level 3 Balance ASSETS AFS securities: U.S. government and agency securities $ — $ 11,677 $ — $ 11,677 Obligations of states and political subdivisions — 899,098 — 899,098 Corporate and other bonds (1) — 147,608 — 147,608 Mortgage-backed securities — 1,637,035 — 1,637,035 Other securities — 1,625 — 1,625 Loans held for sale — 49,082 — 49,082 Derivatives: Interest rate swap — 106,450 — 106,450 Fair value hedges — 2,139 — 2,139 LIABILITIES Derivatives: Interest rate swap $ — $ 106,450 $ — $ 106,450 Cash flow hedges — 1,808 — 1,808 Fair value hedges — 7,949 — 7,949 (1) Other bonds include asset-backed securities.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis Certain assets are measured at fair value on a nonrecurring basis in accordance with U.S. GAAP. Adjustments to the fair value of these assets usually result from the application of lower-of-cost-or-market accounting or write-downs of individual assets after they are evaluated for impairment. The primary assets accounted for at fair value on a nonrecurring basis are related to foreclosed properties, former bank premises, and collateral-dependent loans that are individually assessed. When the asset is secured by real estate, the Company measures the fair value utilizing an income or market valuation approach based on an appraisal conducted by an independent, licensed appraiser using observable market data. Management may discount the value from the appraisal in determining the fair value if, based on its understanding of the market conditions, the collateral had been impaired below the appraised value (Level 3). The assets for which a nonrecurring fair value measurement was recorded during the period ended March 31, 2021 and December 31, 2020 was $12.2 million and $12.7 million, respectively. The nonrecurring valuation adjustments for these assets did not have a material impact on the Company’s consolidated financial statements. Fair Value of Financial Instruments ASC 825, Financial Instruments, requires disclosure about fair value of financial instruments for interim periods and excludes certain financial instruments and all non-financial instruments from its disclosure requirements. Accordingly, the aggregate fair value amounts presented may not necessarily represent the underlying fair value of the Company. Cash and Cash Equivalents For those short-term instruments, the carrying amount is a reasonable estimate of fair value. HTM Securities The Company’s investment portfolio is primarily valued using fair value measurements that are considered to be Level 2. The Company has contracted with a third-party portfolio accounting service vendor for valuation of its securities portfolio. The vendor’s primary source for security valuation is ICE Data Services, which evaluates securities based on market data. ICE Data Services utilizes evaluated pricing models that vary by asset class and include available trade, bid, and other market information. Generally, the methodology includes broker quotes, proprietary models, vast descriptive terms and conditions databases, as well as extensive quality control programs. The vendor utilizes proprietary valuation matrices for valuing all municipals securities. The initial curves for determining the price, movement, and yield relationships within the municipal matrices are derived from industry benchmark curves or sourced from a municipal trading desk.

The Company primarily uses Bloomberg Valuation Service, an independent information source that draws on quantitative models and market data contributed from over 4,000 market participants, to validate third party valuations. Any material differences between valuation sources are researched by further analyzing the various inputs that are utilized by each pricing source. No material differences were identified during the validation as of March 31, 2021 and December 31, 2020. The Company’s level 3 securities are a result of the Access acquisition and are comprised of asset-backed securities and municipal bonds. Valuations of the asset-backed securities are provided by a third party vendor specializing in the SBA markets, and are based on underlying loan pool information, market data, and recent trading activity for similar securities. Valuations of the municipal bonds are provided by a third party vendor that specializes in hard-to-value securities, and are based on a discounted cash flow model and considerations for the complexity of the instrument, likelihood it will be called and credit ratings. The Company reviews the valuation of both security types for reasonableness in the context of market conditions and to similar bonds in the Company’s portfolio. Any material differences between valuation sources are researched by further analyzing the various inputs that are utilized by each pricing source. No material differences were identified during the validation as of March 31, 2021 and December 31, 2020. Loans and Leases The fair value of loans and leases were estimated using an exit price, representing the amount that would be expected to be received if the Company sold the loans and leases. The fair value of performing loans and leases were estimated through use of discounted cash flows. Credit loss assumptions were based on market PD/LGD for loan and lease cohorts. The discount rate was based primarily on recent market origination rates. Fair value of loans and leases individually assessed and their respective levels within the fair value hierarchy are described in the previous section related to fair value measurements of assets that are measured on a nonrecurring basis. Bank Owned Life Insurance The carrying value of BOLI approximates fair value. The Company records these policies at their cash surrender value, which is estimated using information provided by insurance carriers. Deposits The fair value of demand deposits, savings accounts, and certain money market deposits is the amount payable on demand at the reporting date. The fair value of certificates of deposits were valued using a discounted cash flow calculation that includes a market rate analysis of the current rates offered by market participants for certificates of deposits that mature in the same period. Accrued Interest The carrying amounts of accrued interest approximate fair value. The carrying values and estimated fair values of the Company’s financial instruments at March 31, 2021 and December 31, 2020 are as follows (dollars in thousands): Fair Value Measurements at March 31, 2021 using Quoted Prices Significant in Active Other Significant Markets for Observable Unobservable Total Fair Identical Assets Inputs Inputs Value Carrying Value Level 1 Level 2 Level 3 Balance ASSETS Cash and cash equivalents $ 400,880 $ 400,880 $ — $ — $ 400,880 AFS securities 2,697,043 — 2,697,043 — 2,697,043 HTM securities 543,575 — 593,589 12,770 606,359 Restricted stock 76,824 — 76,824 — 76,824 Loans held for sale 49,082 — 49,082 — 49,082 Net loans 14,129,369 — — 13,950,754 13,950,754 Derivatives: Interest rate swap 106,450 — 106,450 — 106,450 Fair value hedges 2,139 — 2,139 — 2,139 Accrued interest receivable 74,603 — 74,603 — 74,603 BOLI 328,627 — 328,627 — 328,627 LIABILITIES Deposits $ 16,298,017 $ — $ 16,328,962 $ — $ 16,328,962 Borrowings 563,600 — 538,488 — 538,488 Accrued interest payable 3,561 — 3,561 — 3,561 Derivatives: Interest rate swap 106,450 — 106,450 — 106,450 Cash flow hedges 1,808 — 1,808 — 1,808 Fair value hedges 7,949 — 7,949 — 7,949 Fair Value Measurements at December 31, 2020 using Quoted Prices Significant in Active Other Significant Markets for Observable Unobservable Total Fair Identical Assets Inputs Inputs Value Carrying Value Level 1 Level 2 Level 3 Balance ASSETS Cash and cash equivalents $ 493,294 $ 493,294 $ — $ — $ 493,294 AFS securities 2,540,419 — 2,540,419 — 2,540,419 HTM securities 544,851 — 606,496 13,269 619,765 Restricted stock 94,782 — 94,782 — 94,782 Loans held for sale 96,742 — 96,742 — 96,742 Net loans 13,860,774 — — 13,710,640 13,710,640 Derivatives: Interest rate swap 163,360 — 163,360 — 163,360 Accrued interest receivable 75,757 — 75,757 — 75,757 BOLI 326,892 — 326,892 — 326,892 LIABILITIES Deposits $ 15,722,765 $ — $ 15,763,991 $ — $ 15,763,991 Borrowings 840,717 — 821,516 — 821,516 Accrued interest payable 2,516 — 2,516 — 2,516 Derivatives: Interest rate swap 163,360 — 163,360 — 163,360 Fair value hedges 12,483 — 12,483 — 12,483 The Company assumes interest rate risk (the risk that general interest rate levels will change) as a result of its normal operations. As a result, the fair values of the Company’s financial instruments will change when interest rate levels change and that change may be either favorable or unfavorable to the Company. Management attempts to match maturities of assets and liabilities to the extent believed necessary to minimize interest rate risk. Borrowers with fixed rate obligations, however, are less likely to prepay in a rising rate environment and more likely to prepay in a falling rate environment. Conversely, depositors who are receiving fixed rates are more likely to withdraw funds before maturity in a rising rate environment and less likely to do so in a falling rate environment. Management monitors rates and maturities of assets and liabilities and attempts to minimize interest rate risk by adjusting terms of new loans and deposits and by investing in securities with terms that mitigate the Company’s overall interest rate risk.

Revenue from Contract with Customer [Abstract]
REVENUE	11. REVENUE The majority of the Company’s noninterest income comes from short term contracts associated with fees for services provided on deposit accounts, credit cards, and wealth management accounts, and mortgage banking and is being accounted for in accordance with Topic 606. Typically, the duration of a contract does not extend beyond the services performed; therefore, the Company concluded that discussion regarding contract balances is immaterial. The Company’s performance obligations on revenue from interchange fees and deposit accounts are generally satisfied immediately, when the transaction occurs, or by month-end. Performance obligations on revenue from fiduciary and asset management fees are generally satisfied monthly or quarterly. For a majority of fee income on deposit accounts the Company is a principal, controlling the promised good or service before transferring it to the customer. For the majority of income related to wealth management income, the Company is an agent, responsible for arranging for the provision of goods and services by another party. Mortgage banking income is earned when the originated loans are sold to an investor on the secondary market. The loans are classified as loans held for sale prior to being sold. Additionally, the changes in fair value of the loans held for sale, loan commitments, and related derivatives are included in mortgage banking income. Noninterest income disaggregated by major source, for the three months ended March 31, 2021 and 2020, consisted of the following (dollars in thousands): Three Months Ended March 31, March 31, 2021 2020 Noninterest income: Deposit Service Charges (1) Overdraft fees $ 3,081 $ 5,765 Maintenance fees & other 2,428 1,813 Other service charges, commissions, and fees (1) 1,701 1,624 Interchange fees (1) 1,847 1,625 Fiduciary and asset management fees (1) Trust asset management fees 2,908 2,827 Registered advisor management fees 2,327 2,088 Brokerage management fees 1,240 1,069 Mortgage banking income 8,255 2,022 Gains on securities transactions 78 1,936 Bank owned life insurance income 2,265 2,049 Loan-related interest rate swap fees 1,754 3,948 Other operating income (2) 3,101 2,141 Total noninterest income $ 30,985 $ 28,907 (1) Income within scope of Topic 606.

Segment Reporting [Abstract]
SEGMENT REPORTING	13. SEGMENT REPORTING Operating segments are components of a business about which separate financial information is available and evaluated regularly by the chief operating decision makers in deciding how to allocate resources and assessing performance. The Bank is the Company’s only reportable operating segment upon which management makes decisions regarding how to allocate resources and assess performance. While the Company’s chief operating decision makers do have some limited financial information about its various financial products and services, that information is not complete since it does not include a full allocation of revenue, costs, and capital from key corporate functions; therefore, the Company evaluates financial performance on the Company-wide basis. Management continues to evaluate these business units for separate reporting as facts and circumstances change.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]
The Company	The Company Headquartered in Richmond, Virginia, Atlantic Union Bankshares Corporation (Nasdaq: AUB) is the holding company for Atlantic Union Bank. Atlantic Union Bank has 129 branches and approximately 150 ATMs located throughout Virginia, and in portions of Maryland and North Carolina. Atlantic Union Bank Wealth Management is a brand name used by Atlantic Union Bank and certain affiliates when providing trust, wealth management, private banking, and investment advisory products and services. Certain non-bank affiliates of Atlantic Union Bank include: Old Dominion Capital Management, Inc., and its subsidiary, Outfitter Advisors, Ltd., and Dixon, Hubard, Feinour, & Brown, Inc., which provide investment advisory services, Atlantic Union Financial Consultants, LLC, which provides brokerage services; and Union Insurance Group, LLC, which offers various lines of insurance products. Effective March 1, 2021, Middleburg Financial, the Bank’s wealth management division was rebranded to Atlantic Union Bank Wealth Management, and Middleburg Investment Services, LLC changed its name to Atlantic Union Financial Consultants, LLC. The unaudited consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. The unaudited consolidated financial statements have been prepared in accordance with U.S. GAAP for interim financial information and follow general practice within the banking industry. Accordingly, the unaudited consolidated financial statements do not include all the information and footnotes required by U.S. GAAP for complete financial statements; however, in the opinion of management all adjustments necessary for a fair presentation of the results of the interim periods presented have been made. The results of operations for the interim periods are not necessarily indicative of the results that may be expected for the full year or any other period. The unaudited consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto included in the Company’s 2020 Form 10-K. Certain prior period amounts have been reclassified to conform to current period presentation.
Adoption of New Accounting Standards	Adoption of New Accounting Standards In March 2020, the FASB issued Topic 848. This guidance provides temporary, optional guidance to ease the potential burden in accounting for reference rate reform associated with the LIBOR transition. LIBOR and other interbank offered rates are widely used benchmark or reference rates that have been used in the valuation of loans, derivatives, and other financial contracts. Global capital markets are going to be required to move away from LIBOR and other interbank offered rates and toward rates that are more observable or transaction based and less susceptible to manipulation. Topic 848 provides optional expedients and exceptions for applying GAAP to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. Topic 848 is intended to help stakeholders during the global market-wide reference rate transition period. The amendments are effective as of March 12, 2020 through December 31, 2022 and can be adopted at an instrument level. As of March 31, 2021, the Company utilized the expedient to assert probability of the hedged interest, regardless of any expected modification in terms related to reference rate reform for the newly executed cash flow hedges. The Company expects to incorporate other components of Topic 848 at a later date. This amendment does not have a material impact on the consolidated financial statements. On January 1, 2021, the Company adopted Topic 740. This guidance was issued to simplify accounting for income taxes by removing specific technical exceptions that often produce information difficult for users of financial statements to understand. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. The Company’s adoption of Topic 740 did not have a material impact on the consolidated financial statements.
Cash and Cash Equivalents	Cash and Cash Equivalents For purposes of reporting cash flows, the Company defines cash and cash equivalents as cash, cash due from banks, interest-bearing deposits in other banks, money market investments, other interest-bearing deposits, and federal funds sold. Restricted cash is disclosed in Note 7 “Commitments and Contingencies” and is comprised of cash maintained at various correspondent banks as collateral for the Company’s derivative portfolio and is included in interest-bearing deposits in other banks in the Company’s Consolidated Balance Sheets. In addition, the Company is required to maintain reserve balances with the Federal Reserve Bank based on the type and amount of deposits; however, on March 15, 2020 the Federal Reserve Board announced that reserve requirement ratios would be reduced to zero percent effective March 26, 2020 due to economic conditions, which eliminated the reserve requirement for all depository institutions.
Accrued Interest Receivable	Accrued Interest Receivable The Company has elected to exclude accrued interest from the amortized cost basis in its determination of the ALLL, as well as the ACL reserve for securities. Accrued interest receivable totaled $57.4 million and $56.7 million on loans held for investment, $5.1 million and $6.8 million on HTM securities, and $11.7 million and $11.9 million on AFS securities at March 31, 2021 and December 31, 2020, respectfully, and is included in “Other Assets” on the Company’s Consolidated Balance Sheets. The Company’s policy is to write off accrued interest receivable through reversal of interest income when it becomes probable the Company will not be able to collect the accrued interest. For the quarters ended March 31, 2021 and March 31, 2020, accrued interest receivable write offs were not material to the Company’s consolidated financial statements.
