In the event that we become insolvent, are placed in receivership or conservatorship, or are liquidated or reorganized, Senior Indebtedness and secured indebtedness will be entitled to be paid in full from our assets before any payment may be made with respect to the Notes. Holders of the Notes will participate in our remaining assets, if any, ratably with all holders of our unsecured, subordinated indebtedness that is on a parity with the Notes. In any of the foregoing events, we may not have sufficient assets to pay all amounts owing on the Notes and other parity indebtedness. See “Description of the Notes.”

The Notes are structurally subordinated to the obligations of our subsidiaries, and the holders of those obligations will be entitled to receive payment in full of those obligations before we participate in any distribution of the assets of our subsidiaries in the event of their liquidation or insolvency.

The Notes are unsecured, subordinated obligations solely of the Company and are not obligations of our subsidiaries or any of our affiliates. The Bank is a separate and distinct legal entity from the Company and its other subsidiaries. Our subsidiaries have no obligation to pay any amounts to the Company, including any dividends, to make any other distributions to the Company or to provide the Company with funds to meet any of its obligations. Our rights and the rights of our creditors, including the holders of the Notes, to participate in any distribution of the assets of our subsidiaries (either as a stockholder or as a creditor), upon a liquidation, reorganization, insolvency or receivership of any such subsidiary (and the consequent right of the holders of the Notes to participate in those assets after repayment of our senior indebtedness), will be subject to the claims of the creditors of such subsidiary, including depositors. As a consequence of the foregoing, the Notes are structurally subordinated to the liabilities of our subsidiaries.

We are a bank holding company and, therefore, may not be able to receive dividends from the Bank in amounts needed to service our debt.

State and federal laws and regulations may restrict the ability of the Bank to issue dividends to us. Similarly, state and federal laws and regulations place certain limitations and restrictions on the ability of the Bank to extend credit or otherwise advance funds to us, regardless of any earnings or income generated by it. Accordingly, holders of the Notes may have to rely solely on our assets and cash flow for payments of principal

and interest, and not those of our subsidiaries. Our standalone assets and cash flow could be insufficient to make such payments on a timely basis or at all.

As a bank holding company, our ability to declare and pay interest and principal on the Notes is subject to Federal Reserve regulations and guidance regarding capital adequacy. Moreover, under the “source of strength” doctrine that was codified by the Dodd-Frank Wall Street Reform and Consumer Protection Act and Federal Reserve policy, the Federal Reserve may require a bank holding company to act as a source of financial and managerial strength to each of its banking subsidiaries and commit resources to their support. Such support may be required at times when a holding company may not otherwise be inclined to provide it. A bank holding company in certain circumstances could be required to guarantee the capital plan of an undercapitalized banking subsidiary in order for such a plan to be accepted by the regulators. In the event of a bank holding company’s bankruptcy under Chapter 11 of the U.S. Bankruptcy Code, the bankruptcy trustee will be deemed to have assumed and is required to cure immediately any deficit under any commitment by the debtor holding company to any of the federal banking agencies to maintain the capital of an insured depository institution, and any claim for breach of such obligation will generally have priority over most other unsecured claims, including the Notes.

The Notes are not savings accounts or deposits of any bank, are not insured by the FDIC or any other government agency, and are not guaranteed by any of our affiliates.

The Notes are unsecured, subordinated obligations solely of the Company. The Notes are not savings accounts or deposits of any bank, including that of Atlantic Union Bank, and are not insured by the FDIC or any other governmental agency. Accordingly, the Notes are subject to investment risk, including, without limitation, loss of principal. The Notes are not obligations of, nor are they guaranteed by, the Bank or any of the Bank’s affiliates or subsidiaries and may not be used as collateral for a loan from the Bank. There are no other arrangements that enhance the seniority of the Notes in relation to the Company’s senior indebtedness.

The Notes are subject to limited rights of acceleration and may only be accelerated in the event we are subject to any insolvency, receivership, conservatorship, liquidation or a similar proceeding.

Payment of principal of the Notes may be accelerated by the trustee or the holders of the Notes only in the event of insolvency, receivership, conservatorship, liquidation or similar proceeding of the Company. Thus, you have no right to accelerate the payment of principal of the Notes if the Company fails in the performance of any of its other obligations under the Notes. The Federal Reserve could seek to require us to obtain prior regulatory approval to pay interest on the Notes if our capital was determined to be insufficient by the Federal Reserve or would be deemed by the Federal Reserve insufficient upon such payment.

The limited covenants relating to the Notes do not protect you. We have the ability to issue additional subordinated notes or incur additional debt under the terms of the Notes or otherwise.

The covenants in the Notes are limited. The Notes do not limit the Company’s ability to issue additional subordinated notes or to incur additional debt, including Senior Indebtedness and other indebtedness of any type. Our incurrence of additional debt or liabilities may adversely affect our ability to pay our obligations on the Notes, the credit ratings on the Notes, and the liquidity and market values of our Notes. The Notes contain no restrictions on granting security interests or liens on our assets or issuing or repurchasing our other securities. As a result, the Notes generally do not protect you in the event of an adverse change in the Company’s financial condition or results of operations.

In addition, the Company is not required to maintain any financial ratios or specific levels of capital and surplus or liquidity in connection with the Notes. The Notes will not contain any provision that would provide protection to their holders against a decline in credit quality resulting from a merger, takeover, recapitalization, or similar restructuring of the Company or its affiliates or significant sales of the capital stock by the holders of such stock or any other event involving the Company or its affiliates that may adversely affect the credit quality of the Company.

TABLE OF CONTENTS

If an active and liquid trading market for the Notes does not develop or continue, the market price of the Notes may decline and you may be unable to sell your Notes.

The Notes are a new issue of securities for which there is currently no public market. We do not intend to list the Notes on any national securities exchange or include the Notes in any automated dealer quotation system. An active trading market may not develop for the Notes. The Notes may not be exchanged for denominations smaller than $1,000 to facilitate trading or otherwise. Although the underwriters have indicated that they intend to make a market in the Notes, they may, in their discretion, discontinue market making activities at any time. Even if a trading market for the Notes develops, the market may not be liquid or continue. If an active trading market does not develop or continue, you may be unable to resell your Notes or may only be able to sell them at a substantial discount from your purchase price.

Our credit ratings may not reflect all risks of an investment in the Notes.

Actual or anticipated changes in the credit ratings assigned to the Notes, if any, may not reflect all risks related to our business, the structure and other factors on any trading market, if any, for, or trading value of, the Notes. In addition, actual or anticipated changes in our credit ratings will generally affect any trading market, if any, for, or trading value of, the Notes. Moreover, ratings do not reflect market prices or suitability of a security for a particular investor. Accordingly, you should consult your own financial and legal advisors as to the risks entailed by an investment in the Notes and the suitability of investing in the Notes in light of your particular circumstances. Credit ratings are not a recommendation to buy, sell or hold any securities, including the Notes, and may be revised or withdrawn at any time by the credit rating organization in its sole discretion. In addition, credit rating agencies continually review their ratings for the companies that they follow, including us. The credit rating agencies also evaluate the financial services industry as a whole and may change their credit rating for us and our securities, including the Notes, based on their overall view of our industry. If a rating on the Notes, us or our other securities is lowered by a rating agency in the future, the trading price of the Notes could decline significantly.

The price at which you will be able to sell your Notes prior to maturity will depend on a number of factors and may be substantially less than the amount you originally invest.

We believe that the value of the Notes in the secondary market, if any, will be affected by the supply and demand of the Notes, their interest rate, ranking and a number of other factors. Some of these factors are interrelated in complex ways. As a result, the effect of any one factor may be offset or magnified by the effect of another factor. The following paragraphs describe certain effects we anticipate on the market value of the Notes of a change in certain factors, assuming all other conditions remain constant.

We expect that the market value of the Notes will be affected by changes or anticipated changes in United States interest rates, including the shape of the yield curve. In general, for example, if United States interest rates increase, the market value of the Notes may decrease.

Actual or anticipated changes in our credit ratings, financial condition or results of operations may affect the market value of the Notes. See “—Our credit ratings may not reflect all risks of an investment in the Notes.”

The effect of any changes in such factors could be offset, in whole or in part, by other changes. For example, an improvement in our credit rating could be offset by increases in market interest rates.

We may be able to redeem the Notes at any time upon the occurrence of certain events.

By their terms, the Notes may be redeemed by us at any time upon the occurrence of certain events involving the capital or tax treatment of the Notes. In particular, upon our determination in good faith that an event has occurred that would constitute a “Tier 2 capital event,” “tax event” or “1940 Act event,” we may, at our option, redeem in whole, but not in part, the Notes, subject to the approval of the Federal Reserve. See “Description of the Notes—Redemption.” If we redeem the Notes, you may not be able to reinvest the redemption price you receive in a similar security.

S-8

TABLE OF CONTENTS

Investors should not expect us to redeem the Notes on the date they become redeemable or on any particular date after they become redeemable.

The Notes have no mandatory redemption date and are not redeemable at the option of investors. By their terms, the Notes may be redeemed by us at our option, either in whole or in part, on , 2026 and on any interest payment date thereafter, or, in whole but not in part, within 90 days of the occurrence of certain changes relating to a tax event, capital event or investment company event, as described below under “Description of the Notes—Redemption.” Any decision we may make at any time to propose a redemption of the Notes will depend upon, among other things, our evaluation of our capital position, including for capital ratio purposes, the composition of our stockholders’ equity and general market conditions at that time. In addition, our right to redeem the Notes is subject to limitations established by the Federal Reserve’s guidelines applicable to bank holding companies, and under current regulatory rules and regulations we would need regulatory approval to redeem the Notes. We cannot guarantee that the Federal Reserve would approve any redemption of the Notes that we may propose.

The amount of interest payable on the Notes will vary after , 2026.

During the fixed rate period, the Notes will bear interest at a rate of % per annum. Thereafter, the Notes will bear interest at an annual floating rate equal to the Benchmark rate (which is expected to be Three-Month Term SOFR) plus a spread of basis points, subject to the applicable provisions under “Description of the Notes—Payment of Principal and Interest.” The per annum interest rate that is determined at the reference time for the floating rate interest period will apply to the entire quarterly interest period following such determination date even if the Benchmark rate increases during that period.

Floating rate notes bear additional significant risks not associated with fixed rate debt securities. These risks include fluctuation of the interest rates and the possibility that you will receive an amount of interest that is lower than expected. We have no control over a number of matters that may impact prevailing interest rates, including, without limitation, economic, financial, and political events that are important in determining the existence, magnitude, and longevity of market volatility, and other risks and their impact on the value of, or payments made on, the Notes. In recent years, interest rates have been volatile, and that volatility may be expected in the future.

SOFR differs fundamentally from, and may not be a comparable substitute for, U.S. dollar LIBOR.

In June 2017, the Alternative Reference Rates Committee, or ARRC. convened by the Federal Reserve and the Federal Reserve Bank of New York, or the FRBNY, announced SOFR as its recommended alternative to the London Interbank Offered Rate, or LIBOR, for U.S. dollar obligations. However, because SOFR is a broad U.S. Treasury repurchase agreement, or repo, financing rate that represents overnight secured funding transactions, it differs fundamentally from LIBOR. For example, SOFR is a secured overnight rate, while LIBOR is an unsecured rate that represents interbank funding. In addition, because SOFR is a transaction-based rate, it is backward-looking, whereas LIBOR is forward-looking. Because of these and other differences, there is no assurance that SOFR will perform in the same way as LIBOR would have performed at any time, and there is no guarantee that it is a comparable substitute for LIBOR.

Any failure of SOFR to gain market acceptance could adversely affect holders of the Notes.

SOFR may fail to gain market acceptance. SOFR was developed for use in certain U.S. dollar derivatives and other financial contracts as an alternative to LIBOR in part because it is considered to be a good representation of general funding conditions in the overnight U.S. Treasury repo market. However, as a rate based on transactions secured by U.S. Treasury securities, SOFR does not measure bank-specific credit risk and, as a result, is less likely to correlate with the unsecured short-term funding costs of banks. This may mean that market participants would not consider SOFR to be a comparable substitute or successor for all of the purposes for which LIBOR historically has been used (including, without limitation, as a representation of the unsecured short-term funding costs of banks), which may, in turn, lessen its market acceptance. Any failure of SOFR to gain market acceptance could adversely affect the yield on, value of, and market for the Notes.

TABLE OF CONTENTS

Investors should not rely on indicative or historical data concerning SOFR.

The interest rate during the floating rate period will be determined using Three-Month Term SOFR (unless a Benchmark Transition Event and its related Benchmark Replacement Date occur with respect to Three-Month Term SOFR, in which case the rate of interest will be based on the next-available Benchmark Replacement). In the following discussion of SOFR, when we refer to SOFR-linked Notes, we mean the Notes at any time when the interest rate on the Notes is or will be determined based on SOFR, including Three-Month Term SOFR.

SOFR is published by FRBNY and is intended to be a broad measure of the cost of borrowing cash overnight collateralized by U.S. Treasury securities. FRBNY reports that SOFR includes all trades in the Broad General Collateral Rate, plus bilateral U.S. Treasury repo transactions cleared through the delivery-versus-payment service offered by the Fixed Income Clearing Corporation, or the FICC, a subsidiary of DTCC). SOFR is filtered by FRBNY to remove a portion of the foregoing transactions considered to be “specials.” According to FRBNY, “specials” are repos for specific-issue collateral which take place at cash-lending rates below those for general collateral repos because cash providers are willing to accept a lesser return on their cash in order to obtain a particular security.

FRBNY reports that SOFR is calculated as a volume-weighted median of transaction-level tri-party repo data collected from The Bank of New York Mellon, which currently acts as the clearing bank for the tri-party repo market, as well as general collateral finance repo transaction data and data on bilateral U.S. Treasury repo transactions cleared through the FICC’s delivery-versus-payment service.

FRBNY states that it obtains information from DTCC Solutions LLC, an affiliate of DTCC. FRBNY currently publishes SOFR daily on its website at https://apps.newyorkfed.org/markets/autorates/sofr. FRBNY states on its publication page for SOFR that use of SOFR is subject to important disclaimers, limitations, and indemnification obligations, including that FRBNY may alter the methods of calculation, publication schedule, rate revision practices, or availability of SOFR at any time without notice. The foregoing Internet website is an inactive textual reference only, meaning that the information contained on the website is not part of this prospectus supplement or the accompanying prospectus or incorporated by reference herein or therein.

FRBNY started publishing SOFR in April 2018. FRBNY has also started publishing historical indicative SOFRs dating back to 2014, although such historical indicative data inherently involves assumptions, estimates and approximations. Investors should not rely on such historical indicative data or on any historical changes or trends in SOFR as an indicator of the future performance of SOFR. Since the initial publication of SOFR, daily changes in the rate have, on occasion, been more volatile than daily changes in comparable benchmark or market rates, and SOFR over time may bear little or no relation to the historical actual or historical indicative data. In addition, the return on and value of the Notes may fluctuate more than floating rate securities that are linked to less volatile rates.

Changes in SOFR could adversely affect holders of the Notes.

Because SOFR is published by FRBNY based on data received from other sources, we have no control over its determination, calculation, or publication. There is no assurance that SOFR will not be discontinued or fundamentally altered in a manner that is materially adverse to the interests of investors in the Notes. If the manner in which SOFR is calculated is changed, that change may result in a reduction in the amount of interest that accrues on the Notes during the floating rate period, which may adversely affect the trading prices of the Notes. Further, if the Benchmark rate on the Notes during the floating rate period on any determination date declines to zero or becomes negative, the interest rate will be deemed to equal zero. In addition, once the Benchmark rate for the Notes for each interest period during the floating rate period is determined by the calculation agent on the determination date, interest on the Notes shall accrue at such Benchmark rate for the applicable interest period and will not be subject to change during such interest period. There is no assurance that changes in SOFR will not have a material adverse effect on the yield on, value of, and market for the Notes.

S-10

TABLE OF CONTENTS

The interest rate for the Notes during the floating rate period may be determined based on a rate other than Three-Month Term SOFR.

Under the terms of the Notes, the interest rate on the Notes for each interest period during the floating rate period will be based on Three-Month Term SOFR, a forward-looking term rate for a tenor of three months that will be based on SOFR. On July 29, 2021, the ARRC formally recommended the use of the CME Group’s computation of forward-looking SOFR term rates. Uncertainty surrounding the adoption and use of forward-looking term rates based on SOFR could have a material adverse effect on the return on, value of and market for the Notes. If, at the commencement of the floating rate period for the Notes, the calculation agent determines that the use of a forward-looking rate for a tenor of three months based on SOFR is not administratively feasible, then the next-available Benchmark Replacement under the benchmark transition provisions will be used to determine the interest rate on the Notes during the floating rate period (unless a Benchmark Transition Event and its related Benchmark Replacement Date occur with respect to that next-available Benchmark Replacement).

Under the terms of the Notes, the calculation agent is expressly authorized to make determinations, decisions or elections with respect to technical, administrative or operational matters that it decides are appropriate to reflect the use of Three-Month Term SOFR as the interest rate basis for the Notes, which are defined in the terms of the Notes as “Three-Month Term SOFR Conventions.” The calculation agent’s determination and implementation of any Three-Month Term SOFR Conventions could result in adverse consequences to the amount of interest that accrues on the Notes during the floating rate period, which could adversely affect the return on, value of and market for the Notes.

Any Benchmark Replacement may not be the economic equivalent of Three-Month Term SOFR.

Under the benchmark transition provisions of the Notes, if the calculation agent determines that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to Three-Month Term SOFR, then the floating interest rate on the Notes for each interest period during the floating rate period will be determined using the next-available Benchmark Replacement (which may include a related Benchmark Replacement Adjustment). However, the Benchmark Replacement may not be the economic equivalent of Three-Month Term SOFR. For example, Compounded SOFR, the first-available Benchmark Replacement, is the compounded average of the daily SOFR calculated in arrears, while Three-Month Term SOFR is intended to be a forward-looking rate with a tenor of three months. In addition, very limited market precedent exists for securities that use Compounded SOFR as the rate basis, and the method for calculating Compounded SOFR in those precedents varies. Further, the ISDA Fallback Rate, which is another Benchmark Replacement, has not yet been established and may change over time.

Holders of the Notes will have no rights against the publishers of SOFR (or, if applicable, the Benchmark Replacement).

Holders of the Notes will have no rights against the publishers of SOFR (or, if applicable, the Benchmark Replacement), even though the amount they receive on each interest payment date after , 2026 will depend on the level of Three-Month Term SOFR (or, if applicable, the Benchmark Replacement). The publishers of SOFR or any Benchmark Replacement rate are not in any way involved in this offering and have no obligations relating to the Notes or the holders of the Notes.

The implementation of Benchmark Replacement Conforming Changes could adversely affect holders of the Notes.

Under the benchmark transition provisions of the Notes, if Three-Month Term SOFR has been discontinued or if a particular Benchmark Replacement or Benchmark Replacement Adjustment cannot be determined, then the next-available Benchmark Replacement or Benchmark Replacement Adjustment will apply. These replacement rates and adjustments may be selected or formulated by: (i) the Relevant Governmental Body (such as the ARRC); (ii) ISDA; or (iii) in certain circumstances, the calculation agent. In addition, the benchmark transition provisions expressly authorize the calculation agent to make certain changes, which are defined in the terms of the Notes as “Benchmark Replacement Conforming Changes,”

S-11

TABLE OF CONTENTS

with respect to, among other things, the determination of interest periods, and the timing and frequency of determining rates and making payments of interest. The application of a Benchmark Replacement and Benchmark Replacement Adjustment, and any implementation of Benchmark Replacement Conforming Changes, could result in adverse consequences to the amount of interest that accrues on the Notes during any interest period during the floating rate period, which could adversely affect the yield on, value of, and market for the Notes. Further, there is no assurance that the characteristics of any Benchmark Replacement will be similar to the then-current Benchmark rate that it is replacing or that any Benchmark Replacement will produce the economic equivalent of the then-current Benchmark rate that it is replacing.

Any market for the SOFR-linked debt securities may be illiquid or unpredictable.

Since SOFR is a relatively new market index, SOFR-linked debt securities likely will have no established trading market when issued, and an established trading market may never develop or be sustained and, even if a trading market does develop, it may be illiquid. Market terms for debt securities indexed to SOFR, such as the spread over the index reflected in interest rate provisions, may evolve over time, and trading prices of the Notes may be lower than those of later-issued SOFR-linked debt securities as a result. Similarly, if SOFR does not prove to be widely used in securities similar to the Notes, the trading price of the Notes may be lower than those of debt securities linked to such rates that are more widely used. Debt securities indexed to SOFR (as the Notes will be) may not be able to be sold at all or may not be able to be sold at prices that will provide a yield comparable to similar investments that have a developed secondary market, and may consequently suffer from increased pricing volatility and market risk.

We, or an affiliate of ours, will or could have authority to make determinations and elections that could affect the return on, value of, and market for the Notes.

Under the terms of the Notes, we may make certain determinations, decisions, and elections with respect to the Benchmark rate on the Notes during the floating rate period, including, without limitation, any determination, decision, or election required to be made by the calculation agent that the calculation agent fails to make. We will make any such determination, decision, or election in our sole discretion, and any such determination, decision, or election that we make could affect the amount of interest that accrues on the Notes during any interest period in the floating rate period. If the calculation agent fails, when required, to make a determination that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred, or fails, when required, to determine the Benchmark Replacement and Benchmark Replacement Adjustment, then we will make those determinations in our sole discretion. Furthermore, we or an affiliate of ours may assume the duties of calculation agent. We cannot assure you that we will appoint an independent third-party calculation agent at any time. Any exercise of discretion by us under the terms of the Notes, including, without limitation, any discretion exercised by us or by an affiliate acting as calculation agent, could present a conflict of interest. In making the required determinations, decisions, and elections, we or an affiliate of ours acting as calculation agent may have economic interests that are adverse to the interest of the holders of the Notes, and those determinations, decisions, or elections could have a material adverse effect on the yield on, value of, and market for the Notes. All determinations, decisions, or elections by us, or by us or an affiliate acting as calculation agent, under the terms of the Notes will be conclusive and binding absent manifest error.

USE OF PROCEEDS

We estimate that the net proceeds from this offering, after deducting the underwriting discounts and estimated expenses, will be approximately $ million. We intend to use the net proceeds from this offering to repay our outstanding $150 million of the 2026 Notes that are redeemable beginning on December 15, 2021 and for general corporate purposes. A notice of redemption was delivered to the holders of such notes on November 15, 2021 with respect to the redemption of all of the outstanding principal amount of such notes on December 15, 2021. The redemption that will occur on December 15, 2021 is not contingent on this offering of the Notes or the amount of proceeds resulting from this offering. Net proceeds contributed to Atlantic Union Bank are anticipated to be used to support the Bank’s growth.

Our management will retain broad discretion to allocate the net proceeds of this offering, and the precise amounts and timing of our use of the net proceeds of this offering will depend upon market conditions, as well as other factors. Until we deploy the proceeds of this offering for the uses described above, we expect to hold such proceeds in cash and short-term investments.

TABLE OF CONTENTS

DESCRIPTION OF THE NOTES

The Notes will be issued by us pursuant to a Subordinated Indenture, dated as of December 5, 2016, between us and U.S. Bank National Association, as trustee, as amended and supplemented by the First Supplemental Indenture, dated as of December 5, 2016, to be further amended and supplemented by a Second Supplemental Indenture, to be dated as of , 2021. We refer to the Subordinated Indenture, as supplemented by the First Supplemental Indenture and the Second Supplemental Indenture, as the “Indenture,” and we refer to U.S. Bank National Association in its capacity as the trustee, as the “Trustee.” The following description of the particular terms of the Notes supplements, and to the extent inconsistent therewith replaces, the description of the general terms and provisions of our subordinated debt securities in the accompanying prospectus, to which description we refer you. The accompanying prospectus sets forth the meaning of certain capitalized terms used but not defined herein.

The following is a brief description of the Notes and the Indenture. It does not purport to be complete in all respects. This description is subject to, and qualified in its entirety by reference to, the Indenture. Upon written or oral request to us at our address set forth under “Where You Can Find More Information,” we will provide at no cost to the requester copies of the Indenture and the Notes.

General

The Notes will be limited initially to $ aggregate principal amount. The Notes will mature on , 2031 (which we refer to as the “maturity date”) unless redeemed prior to such date as described below under “—Redemption.” There is no sinking fund for the Notes. The Notes are not convertible into, or exchangeable for, any equity securities, other securities or other assets of ours or any subsidiary of ours.

The maturity of the Notes may not be accelerated in the absence of certain Events of Default (as such term is defined in the Indenture). There is no right to accelerate the maturity of the Notes if we fail to pay interest on any Note for 30 days after such payment is due, fail to pay the principal on any Note when due, or fail to perform or breach any other covenant or warranty under any Note or in the Indenture. See “—Defaults; Events of Default; Limitation on Suits.”

As a bank holding company, our ability to make payments on the Notes will depend primarily on the receipt of dividends and other distributions from the Bank. There are various regulatory restrictions on the ability of the Bank to pay dividends or make other distributions to us. See “Part 1—Item 1—Business—Supervision and Regulation” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020.

The Notes are not savings accounts, deposits or other obligations of the Bank or any of our subsidiaries and are not insured or guaranteed by the FDIC or any other governmental agency or instrumentality. The Notes are solely our obligations and are neither obligations of, nor guaranteed by, our subsidiary bank, Atlantic Union Bank, or any of our nonbank subsidiaries.

The Notes will be issued in denominations of $1,000 and integral multiples of $1,000 in excess thereof.

Payment of Principal and Interest

Payment of the full principal amount of the Notes will be due on , 2031, unless redeemed prior to such date as described below under “—Redemption.” Principal and, in the case of redemption, interest, if any, due on the maturity date or any earlier date of redemption will be payable against presentation and surrender of the Notes.

The Notes will bear interest (i) at an initial rate of % per year, payable semi-annually in arrears on and of each year (each, a “fixed rate interest payment date”), commencing on , 2022, from and including , 2021 to but excluding , 2026 (the “First Reset Date”) and (ii) thereafter (the “floating rate period”) at an annual floating rate equal to the Benchmark (as defined below) rate (which is expected to be Three-Month Term SOFR (as defined below)) as determined for

the applicable Interest Period (as defined below) plus a spread of basis points, payable quarterly in arrears on , , and of each year (each, a “floating rate interest payment date,” and together with the fixed rate interest payment dates, the “interest payment dates”), commencing on , 2027. Notwithstanding the foregoing, in the event that Three-Month Term SOFR or the applicable Benchmark rate is less than zero, the Three-Month Term SOFR or the applicable Benchmark rate will be deemed to be zero.

Interest on the Notes will accrue from and including the immediately preceding interest payment date in respect of which interest has been paid or duly provided for or, if no interest has been paid or duly provided for, from and including the date of issuance of the Notes, to but excluding the applicable interest payment date or the maturity date or date of earlier redemption, if applicable (each, an “Interest Period”).

For the purpose of calculating the interest on the Notes for each Interest Period during the floating rate period when the Benchmark (as defined below) is Three-Month Term SOFR, “Three-Month Term SOFR” means the rate for Term SOFR (as defined below) for a tenor of three months that is published by the Term SOFR Administrator (as defined below) at the Reference Time (as defined below) for any Interest Period, as determined by the Calculation Agent (as defined below) after giving effect to the Three-Month Term SOFR Conventions. From the commencement of the floating rate period and as long as any of the Notes are outstanding, we shall take such actions as are necessary to ensure that there will be at all times a Calculation Agent appointed. For the avoidance of doubt, if at any time there is no appointed Calculation Agent, we will act as the Calculation Agent.

The Trustee will not be under any duty to succeed to, assume or otherwise perform any of the duties of the Calculation Agent, or to appoint a successor or replacement in the event of the Calculation Agent’s resignation or removal or to replace the Calculation Agent in the event of a default, breach or failure of performance on the part of the Calculation Agent with respect to the Calculation Agent’s duties under the Indenture.

The following definitions apply to the foregoing definition of Three-Month Term SOFR:

“Benchmark” means, initially, Three-Month Term SOFR; provided that if the Calculation Agent determines on or prior to the Reference Time for any Interest Period that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to Three-Month Term SOFR or the then-current Benchmark, then “Benchmark” means the applicable Benchmark Replacement for such Interest Period and any subsequent Interest Periods.

“Calculation Agent” means the agent appointed by us prior to the commencement of the floating interest rate period, which may include the Company or any of its affiliates, or any other successor appointed by us, to act as Calculation Agent.

“FRBNY’s Website” means the website of FRBNY at http://www.newyorkfed.org, or any successor source. The foregoing Internet website is an inactive textual reference only, meaning that the information contained on the website is not part of this prospectus supplement or the accompanying prospectus or incorporated by reference herein or therein.

“Reference Time” with respect to any determination of the Benchmark means (i) if the Benchmark is Three-Month Term SOFR, the time determined by the Calculation Agent after giving effect to the Three-Month Term SOFR Conventions, and (ii) if the Benchmark is not Three-Month Term SOFR, the time determined by the Calculation Agent after giving effect to the Benchmark Replacement Conforming Changes.

“Relevant Governmental Body” means the Federal Reserve and/or the FRBNY, or a committee officially endorsed or convened by the Federal Reserve and/or the FRBNY or any successor thereto.

“SOFR” means the secured overnight financing rate published by the FRBNY, as the administrator of the Benchmark (or a successor administrator), on the FRBNY’s Website.

S-16

TABLE OF CONTENTS

“Term SOFR” means the forward-looking term rate based on SOFR that has been selected or recommended by the Relevant Governmental Body.

“Term SOFR Administrator” means any entity designated by the Relevant Governmental Body as the administrator of Term SOFR (or a successor administrator).

“Three-Month Term SOFR Conventions” means any determination, decision or election with respect to any technical, administrative or operational matter (including with respect to the manner and timing of the publication of Three-Month Term SOFR, or changes to the definition of “Interest Period,” timing and frequency of determining Three-Month Term SOFR with respect to each Interest Period and making payments of interest, rounding of amounts or tenors, and other administrative matters) that the Calculation Agent decides may be appropriate to reflect the use of Three-Month Term SOFR as the Benchmark in a manner substantially consistent with market practice (or, if the Calculation Agent decides that adoption of any portion of such market practice is not administratively feasible or if the Calculation Agent determines that no market practice for the use of Three-Month Term SOFR exists, in such other manner as the Calculation Agent determines is reasonably necessary).

The terms “Benchmark Replacement,” “Benchmark Replacement Conforming Changes,” “Benchmark Replacement Date,” “Benchmark Transition Event” and “Corresponding Tenor” have the meanings set forth below under the heading “—Effect of Benchmark Transition Event.”

Notwithstanding the foregoing paragraphs related to the determination of interest, if the Calculation Agent determines on or prior to the relevant Reference Time that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to Three-Month Term SOFR, then the provisions set forth below under the heading “—Effect of Benchmark Transition Event,” which we refer to as the “benchmark transition provisions,” will thereafter apply to all subsequent determinations of the interest rate on the Notes for each Interest Period during the floating rate period. In accordance with the benchmark transition provisions, after a Benchmark Transition Event and its related Benchmark Replacement Date have occurred, the interest rate on the Notes for each Interest Period during the floating rate period will subsequently be an annual rate equal to the Benchmark Replacement plus basis points.

The determination of Three-Month Term SOFR for each relevant Interest Period by the Calculation Agent will (in the absence of manifest error) be final and binding. The Calculation Agent’s calculation of the amount of any interest payable after the First Reset Date will be maintained on file at the Calculation Agent’s principal offices, and will be provided to the Trustee.

The interest payable on the Notes on any interest payment date, subject to certain exceptions, will be paid to the person in whose name the Notes are registered at the close of business on and , whether or not a Business Day (as defined below), immediately preceding the applicable fixed rate interest payment date or on , , and , whether or not a Business Day, immediately preceding the applicable floating rate interest payment date, as the case may be. Interest payable on an interest payment date will be made by wire transfer in immediately available funds in U.S. dollars at the office of the principal paying agent in the City of New York or, at our option in the event the Notes are not represented by Global Notes (as defined below), by check mailed to the address of the related holders.

In the event that a fixed rate interest payment date or the maturity date or any earlier date of redemption falls on a day that is not a Business Day, then the amounts payable on such date will be paid on the next succeeding Business Day without the accumulation of additional interest. In the event that a floating rate interest payment date falls on a day that is not a Business Day, then such floating rate interest payment date will be postponed to the next succeeding Business Day unless such day falls in the next succeeding calendar month, in which case such floating rate interest payment date will be accelerated to the immediately preceding Business Day, and, in each such case, the amounts payable on such Business Day will include interest accrued to but excluding such Business Day.

“Business Day” means any day other than a Saturday, a Sunday, or a day on which banking institutions in the City of New York are authorized or required by law or executive order to remain closed.

S-17

TABLE OF CONTENTS

Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months during the fixed rate period, and interest will be computed on the basis of the actual number of days during the floating rate period. Dollar amounts resulting from that calculation will be rounded to the nearest cent, with one-half cent being rounded upward.

Any interest which is payable, but is not punctually paid or duly provided for, on any interest payment date (“Defaulted Interest”) will cease to be payable to the holder on the relevant record date by virtue of having been a holder on such date, and such Defaulted Interest may be paid by us to the person in whose name the Notes are registered at the close of business on a special record date for the payment of defaulted interest or in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed if such payment shall be deemed practicable by the Trustee.

If the then-current Benchmark is Three-Month Term SOFR, the Calculation Agent will have the right to establish the Three-Month Term SOFR Conventions, and if any of the foregoing provisions concerning the calculation of the interest rate and interest payments during the floating rate period are inconsistent with any of the Three-Month Term SOFR Conventions determined by the Calculation Agent, then the relevant Three-Month Term SOFR Conventions will apply. Furthermore, if the Calculation Agent determines that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to Three-Month Term SOFR at any time when any of the Notes are outstanding, then the foregoing provisions concerning the calculation of the interest rate and interest payments during the floating rate period will be modified in accordance with the benchmark transition provisions.

Payment of principal on the Notes may be accelerated only in the case of certain events of bankruptcy or insolvency. See “—Defaults; Events of Default; Limitation on Suits.”

No recourse will be available for the payment of principal of, or interest on, any Note, for any claim based thereon, or otherwise in respect thereof, against any stockholder, employee, agent, officer or director, as such, past, present or future, of Atlantic Union Bankshares Corporation or of any successor entity. The Indenture contains no covenants or restrictions restricting the incurrence of debt by us or by our subsidiaries. The Indenture contains no financial covenants and does not restrict us from paying dividends or issuing or repurchasing other securities, and does not contain any provision that would provide protection to the holders of the Notes against a sudden and dramatic decline in credit quality resulting from a merger, takeover, recapitalization, or similar restructuring or any other event involving us or our subsidiaries that may adversely affect our credit quality.

Ranking

The Notes are our general unsecured, subordinated obligations and are:

•

junior in right of payment to all of our existing and future Senior Indebtedness as discussed below;

•

equal in right of payment and upon our liquidation with all of our existing and future unsecured subordinated indebtedness, including our 5.00% Fixed-to-Floating Rate Subordinated Notes due 2026;

•

senior to our obligations relating to any outstanding junior subordinated debt securities issued to our capital trust subsidiaries;

•

effectively senior to our depositary shares;

•

effectively subordinated to any of our existing or future secured indebtedness to the extent of the value of the collateral securing such indebtedness; and

•

effectively subordinated to our future secured indebtedness to the extent of the value of the collateral securing such indebtedness, and structurally subordinated to the existing and future indebtedness of our subsidiaries, including without limitation the Bank’s depositors, liabilities to general creditors and liabilities arising during the ordinary course of business or otherwise.

S-18

TABLE OF CONTENTS

Subordination of the Notes

Our obligation to make any payment on account of the principal and interest on the Notes will be subordinate and junior in right of payment to our obligations to the holders of our Senior Indebtedness. “Senior Indebtedness” is defined in the Indenture to mean all of our:

•

indebtedness for borrowed or purchased money, whether or not evidenced by bonds, debentures, securities, notes, or other written instruments;

•

deferred obligations for the payment of the purchase price of property or assets acquired other than in the ordinary course of business;

•

obligations, contingent or otherwise, under letters of credit, bankers’ acceptances, security purchase facilities and similar transactions;

•

capital lease obligations;

•

obligations with respect to interest rate swap, cap or other agreements, interest rate future or option contracts, currency swap agreements, currency future or option contracts, commodity contracts and other similar agreements;

•

guarantees, endorsements (other than by endorsement of negotiable instruments for collection in the ordinary course of business), and other similar contingent obligations in respect of obligations of others of a type described in the preceding bullets, whether or not classified as a liability on a balance sheet prepared in accordance with accounting principles generally accepted in the United States; and

•

any obligations of ours to our general creditors (as defined for purposes of the capital adequacy regulations of the Federal Reserve);

in each case, whether outstanding on the date that we entered into the Indenture or arising after that time, and other than obligations ranking equally with the Notes or ranking junior to the Notes.

All liabilities of the Bank and our other subsidiaries, including without limitation the Bank’s depositors, liabilities to general creditors, and liabilities arising during our subsidiaries’ ordinary course of business or otherwise, will be effectively senior to the Notes to the extent of the assets of such subsidiaries. As of September 30, 2021, on a consolidated basis, the Company’s outstanding indebtedness and other liabilities totaled approximately $17.3 billion, which includes approximately $16.6 billion of deposit liabilities, no outstanding secured indebtedness that ranks structurally senior to the Notes, $150 million of outstanding subordinated debt securities that rank equal in right of payment to the Notes, and $150.5 million of outstanding junior subordinated debt securities that rank junior to the Notes.

Over the term of the Notes, we will need to rely primarily on dividends from the Bank, which is a state chartered bank, to generate our cash flow to pay interest and principal on our outstanding debt obligations, and to make dividends to our stockholders and other payments on our other securities. Federal and state law and regulation impose certain restrictions on the ability of the Bank to pay dividends to us. See “Risk Factors” above. In addition, our transactions with the Bank are subject to a range of qualitative and quantitative restrictions, including restrictions on the ability of the Bank to make any extensions of credit to us or certain of our affiliates and to invest in our stock or securities. These restrictions prevent us from borrowing from the Bank unless the loans are secured by sufficient collateral and meet other criteria, and also limit the amount of the Bank’s transactions with us to a percentage of the Bank’s capital stock and surplus. These Bank dividend and affiliate transaction restrictions may limit our access to sufficient cash flow to make payments on the Notes.

TABLE OF CONTENTS

to Senior Indebtedness will the holders of the Notes, together with the holders of any of our obligations ranking on a parity with the Notes, be entitled to be paid from our remaining assets the amounts due and owing on account of unpaid principal of and interest on the Notes. In the event and during the continuation of any default in the payment of the principal of, or any premium or interest on any Senior Indebtedness beyond any applicable grace period with respect to such Senior Indebtedness, or in the event that any event of default with respect to any Senior Indebtedness shall have occurred and be continuing permitting the holders of such Senior Indebtedness (or the Trustee or agent on behalf of the holders of such Senior Indebtedness), to declare such Senior Indebtedness due and payable prior to the date on which it would otherwise have become due and payable, unless and until such event of default shall have been cured or waived, or shall have ceased to exist and such acceleration shall have been rescinded or annulled, or in the event any judicial proceeding shall be pending with respect to any such default in payment or event of default, then no payment shall be made by us on account of the principal of, or interest on, the Notes.

Because we are a bank holding company, our right and the rights of our creditors, including holders of the Notes, to participate in any distribution of assets of any of our subsidiaries upon their liquidation, reorganization, dissolution, winding up or otherwise would be subject to the prior claims of creditors of that subsidiary (except to the extent that we are a creditor with a recognized claim). In the event of any such distribution of assets of the Bank due in part to its status as an insured depository institution, the claims of depositors and other general or subordinated creditors of the Bank would be entitled to priority over claims of shareholders the Bank, including us as its parent holding company and any creditor of ours, such as holders of the Notes. As of September 30, 2021, the Bank had $16.6 billion of deposit liabilities, no Federal Home Loan Bank advances and $95 million of customer repurchase agreements to which the Notes will be structurally subordinated.

In the event of our bankruptcy or insolvency, holders of our Senior Indebtedness may receive more, ratably, and holders of the Notes may receive less, ratably, than our other creditors.

The Notes do not contain any limitation on the amount of Senior Indebtedness or other obligations ranking senior to or equally with the indebtedness evidenced by the Notes that may be hereafter incurred by us or our subsidiaries.

No Additional Amounts

In the event that any payment on the Notes is subject to withholding of any U.S. federal income tax or other tax or assessment (as a result of a change in law or otherwise), we will not pay additional amounts with respect to such tax or assessment. For a discussion relating to certain U.S. federal income tax consequences of the ownership and disposition of the Notes, see “Material U.S. Federal Income Tax Considerations.”

Redemption

We may, at our option, beginning with the interest payment date of , 2026, but not prior thereto (except upon the occurrence of certain events specified below), and on any interest payment date thereafter, redeem the Notes, in whole or in part, subject to obtaining the prior approval of the Federal Reserve to the extent such approval is then required under the rules of the Federal Reserve, including capital regulations, at a price equal to 100% of the principal amount of the Notes being redeemed plus interest that is accrued and unpaid to but excluding the date of redemption. The Notes may not otherwise be redeemed prior to maturity, except that we may also, at our option, redeem the Notes at any time, including before , 2026, in whole but not in part, subject to obtaining the prior approval of the Federal Reserve to the extent such approval is then required under the rules of the Federal Reserve, including capital regulations, at a price equal to 100% of the principal amount of the Notes being redeemed plus interest that is accrued and unpaid to but excluding the date of redemption upon the occurrence of:

•

a “Tax Event,” defined in the Indenture to mean the receipt by us of an opinion of independent tax counsel to the effect that as a result of (a) an amendment to or change (including any announced prospective amendment or change) in any law or treaty, or any regulation thereunder, of the United States or any of its political subdivisions or taxing authorities; (b) a judicial decision, administrative

S-20

TABLE OF CONTENTS

action, official administrative pronouncement, ruling, regulatory procedure, regulation, notice or announcement, including any notice or announcement of intent to adopt or promulgate any ruling, regulatory procedure or regulation (any of the foregoing, an “administrative or judicial action”); (c) an amendment to or change in any official position with respect to, or any interpretation of, an administrative or judicial action or a law or regulation of the United States that differs from the previously generally accepted position or interpretation; or (d) a threatened challenge asserted in writing in connection with an audit of our federal income tax returns or positions or a similar audit of any of our Subsidiaries, or a publicly known threatened challenge asserted in writing against any other taxpayer that has raised capital through the issuance of securities that are substantially similar to the Notes, in each case, occurring or becoming publicly known on or after the original issue date of the Notes, there is more than an insubstantial risk that interest payable by us on the Notes is not, or, within 90 days of the date of such opinion, will not be, deductible by us, in whole or in part, for United States federal income tax purposes;

•

a “Tier 2 Capital Event,” defined in the Indenture to mean the receipt by us of an opinion of independent bank regulatory counsel to the effect that as a result of: (a) any amendment to, or change in, the laws, rules or regulations of the United States (including, for the avoidance of doubt, any agency or instrumentality of the United States, including the Federal Reserve and other appropriate federal bank regulatory agencies) or any political subdivision of or in the United States that is enacted or becomes effective after the initial issuance of the Notes; (b) any proposed change in those laws, rules or regulations that is announced or becomes effective after the initial issuance of the Notes; or (c) any official administrative decision or judicial decision or administrative action or other official pronouncement interpreting or applying those laws, rules, regulations, policies, or guidance with respect thereto that is announced after the initial issuance of the Notes, in each case, there is more than an insubstantial risk that we will not be entitled to treat the Notes then outstanding as Tier 2 capital (or its equivalent) for purposes of the capital adequacy rules or regulations of the Federal Reserve (or, as and if applicable, the capital adequacy rules or regulations of any successor appropriate federal banking agency) as then in effect and applicable, for so long as any Note is outstanding; or

•

a “1940 Act Event,” defined in the Indenture to mean our becoming required to register as an investment company pursuant to the Investment Company Act of 1940, as amended.

In the event of any redemption of the Notes, a notice of redemption (which notice may be conditional in our discretion on one or more conditions precedent, and the redemption date may be delayed until such time as any or all of such conditions have been satisfied or revoked by us if we determine that such conditions will not be satisfied) shall be delivered to each holder of Notes not less than 30 nor more than 60 days prior to the redemption date.

Any partial redemption will be made in accordance with DTC’s applicable procedures among all of the holders of the Notes. If any Note is to be redeemed in part only, the notice of redemption relating to such Note shall state the portion of the principal amount thereof to be redeemed. A replacement Note in principal amount equal to the unredeemed portion thereof will be issued in the name of the holder thereof upon cancellation of the original Note. The Notes are not subject to redemption or prepayment at the option of the holders.

Tier 2 Capital

The Notes are intended to qualify as Tier 2 capital under the Federal Reserve’s rules regarding capital adequacy, as the same may be amended or supplemented from time to time. These regulations set forth specific criteria for instruments to qualify as Tier 2 capital. Among other things, the Notes must:

•

be unsecured;

•

have a minimum original maturity of at least five years;

•

be subordinated and junior in right of payment to our bank subsidiary’s obligations to its depositors and to our general creditors;

S-21

TABLE OF CONTENTS

•

not contain provisions permitting the holders of the Notes to accelerate payment of principal or interest prior to maturity except in the event of receivership, insolvency, liquidation or similar proceedings of us or the Bank; and

•

only be callable after a minimum of five years following issuance, except upon the occurrence of certain special events, as described above, and, in any case, subject to obtaining the prior approval of the Federal Reserve or other primary federal regulator.

Defaults; Events of Default; Limitation on Suits

Under the Indenture, an event of default will occur with respect to the Notes only: (i) if we fail to pay interest on the Notes as and when due and such failure continues for 30 days; (ii) if we fail to pay the principal of the Notes as and when due; (iii) if we breach any covenant or agreement contained in the Indenture and such failure continues for 90 days following notice of the same; (iv) if a court enters an order in an involuntary bankruptcy or insolvency proceeding with respect to us that continues unstayed and in effect for a period of 60 consecutive days; (v) if we commence a bankruptcy or insolvency proceeding, consent to the entry of an order in an involuntary bankruptcy or insolvency proceeding, consent to the appointment of a receiver, liquidator or similar official, make a general assignment for the benefit of creditors, or fail generally to pay our debts as they become due; or (vi) in the event of an appointment of a receiver, conservator or similar official for our principal banking subsidiary, Atlantic Union Bank.

If an event of default listed in item (iv), (v) or (vi) above occurs and is continuing, the principal amount and interest shall become immediately and automatically due and payable upon a declaration by the Trustee or the holders of not less than 25% in aggregate principal amount of the Notes.

There is no right of acceleration in the case of a default in the payment of principal of or interest on the Notes or in our non-performance of any other obligation under the Notes or the Indenture. If we default in our obligation to pay any interest on the Notes when due and payable, and such default continues for a period of 30 consecutive days, or if we default in our obligation to pay the principal amount due upon maturity, or if we breach any covenant or agreement contained in the Indenture, then the Trustee may, subject to certain limitations and conditions, seek to enforce its rights and the rights of the holders of Notes of the performance of any covenant or agreement in the Indenture.

The Indenture provides that the Trustee will be under no obligation to exercise any of its rights or powers under the Indenture at the request, or direction of any of the holders of Notes, unless such holders shall have provided to the Trustee indemnity or security acceptable to the Trustee against the costs, expenses and liabilities which may be incurred by it in complying with such request or direction. Subject to certain provisions, the holders of a majority in principal amount of the outstanding Notes will have the right to direct the time, method, and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to the Notes.

No holder of Notes shall have any right to institute any proceeding, judicial or otherwise, with respect to the Indenture, or for the appointment of a receiver or trustee, or for any other remedy under the Indenture, unless:

•

such holder has previously given written notice to the Trustee of a continuing default with respect to the Notes;

•

the holders of not less than 25% in principal amount of the Notes shall have made written request to the Trustee to institute proceedings in respect of such default in its own name as Trustee under the Indenture;

•

such holder or holders have provided to the Trustee indemnity acceptable to the Trustee against the costs, expenses, and liabilities which may be incurred in complying with such request;

•

the Trustee for 60 days after its receipt of such notice, request, and indemnity has failed to institute any such proceeding; and

S-22

TABLE OF CONTENTS

•

no direction inconsistent with such written request has been received by the Trustee during such 60 day-period by the holders of a majority in principal amount of the outstanding Notes.

In any event, the Indenture provides that no one or more of such holders shall have any right under the Indenture to affect, disturb or prejudice the rights of any other holder, or to obtain priority or preference over any of the other holders or to enforce any right under the Indenture, except in the manner provided in the Indenture and for the equal and ratable benefit of all holders of Notes.

Modification and Waiver

The Indenture provides that we and the Trustee may modify or amend the Indenture with, or, in certain cases, without the consent of the holders of a majority in principal amount of outstanding Notes; provided, however, that any modification or amendment may not, without the consent of the holder of each outstanding Note affected thereby:

•

change the maturity date of the principal of, or any installment of interest on, any Note;

•

reduce the principal amount or rate of interest of any Note;

•

reduce the percentage in principal amount of the outstanding Notes, the consent of whose holders is required to modify or amend the Indenture, for any supplemental indenture, or for any waiver of compliance with certain provisions of the Indenture or certain defaults and the consequences thereof under the Indenture;

•

impair the right to institute suit for the enforcement of any payment on or with respect to the Notes; or

•

modify the provisions of the Indenture with respect to subordination of the Notes in a manner adverse to the holders of the Notes.

In addition, the holders of a majority in principal amount of the outstanding Notes may, on behalf of all holders of Notes, waive compliance by us with certain terms, conditions and provisions of the Indenture, as well as any past default and/or the consequences of default, other than any default in the payment of principal or interest or any breach in respect of a covenant or provision that cannot be modified or amended without the consent of the holder of each outstanding Note.

Legal Defeasance and Covenant Defeasance

We may choose to either discharge our obligations under the Indenture and the Notes in a legal defeasance, or to release ourselves from certain or all of our covenant restrictions under the Indenture and the Notes in a covenant defeasance. We may do so, after we irrevocably deposit with the Trustee for the benefit of the holders of the Notes, sufficient cash and/or U.S. government securities to pay the principal of (and premium, if any) and interest and any other sums due on the maturity date or a redemption date of the Notes. If we choose the legal defeasance option, the holders of the Notes will not be entitled to the benefits of the Indenture except for certain limited rights, including registration of transfer and exchange of Notes, replacement of lost, stolen or mutilated Notes and the right to receive payments of the principal of (and premium, if any) and interest on such Notes when such payments are due.

We may discharge our obligations under the Indenture or release ourselves from covenant restrictions only if we meet certain requirements. Among other things, we must deliver to the Trustee an opinion of our legal counsel to the effect that holders of the Notes will not recognize income, gain or loss for federal income tax purposes as a result of such defeasance and will be subject to federal income tax on the same amount, in the same manner and at the same times, as would have been the case if such deposit and defeasance had not occurred. In the case of legal defeasance only, this opinion must be based on either a ruling received from or published by the IRS or a change in the applicable federal income tax law. We may not have a default under the Indenture or the Notes on the date of deposit and, under certain circumstances, 120 days after such deposit. The discharge may not cause the Trustee to have a conflicting interest for purposes of the Trust Indenture Act and may not result in our becoming an investment company in violation of the Investment Company Act of 1940, as amended. The discharge may not violate any of our agreements to which we are a party or by which we are bound.

S-23

TABLE OF CONTENTS

Any defeasance of the Notes pursuant to the Indenture shall be subject to our obtaining the prior approval of the Federal Reserve. Notwithstanding the foregoing, if, due to a change in law, regulation or policy subsequent to the original issue date of the Notes the Federal Reserve no longer requires that defeasance of the Notes be subject to Federal Reserve approval in order for the Notes to be accorded Tier 2 Capital treatment, then no such approval of the FRB will be required for such defeasance.

Effect of Benchmark Transition Event

Benchmark Replacement. If the Calculation Agent determines that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred on or prior to the Reference Time in respect of any determination of the Benchmark on any date, then the Benchmark Replacement will replace the then-current Benchmark for all purposes relating to the Notes during the floating rate period in respect of such determination on such date and all determinations on all subsequent dates.

Benchmark Replacement Conforming Changes. In connection with the implementation of a Benchmark Replacement, the Calculation Agent will have the right to make Benchmark Replacement Conforming Changes from time to time.

Certain Defined Terms As used herein:

“Benchmark Replacement” means the Interpolated Benchmark with respect to the then-current Benchmark, plus the Benchmark Replacement Adjustment (as defined below) for such Benchmark; provided that if (a) the Calculation Agent cannot determine the Interpolated Benchmark as of the Benchmark Replacement Date (as defined below) or (b) the then-current Benchmark is Three-Month Term SOFR and a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to Three-Month Term SOFR (in which event no Interpolated Benchmark (as defined below) with respect to Three-Month Term SOFR shall be determined), then “Benchmark Replacement” means the first alternative set forth in the order below that can be determined by the Calculation Agent as of the Benchmark Replacement Date:

(1) Compounded SOFR (as defined below);

(2) the sum of: (a) the alternate rate that has been selected or recommended by the Relevant Governmental Body as the replacement for the then-current Benchmark for the applicable Corresponding Tenor and (b) the Benchmark Replacement Adjustment;

(3) the sum of: (a) the ISDA Fallback Rate (as defined below) and (b) the Benchmark Replacement Adjustment; and

(4) the sum of: (a) the alternate rate that has been selected by the Calculation Agent as the replacement for the then-current Benchmark for the applicable Corresponding Tenor, giving due consideration to any industry- accepted rate as a replacement for the then-current Benchmark for U.S. dollar-denominated floating rate securities at such time, and (b) the Benchmark Replacement Adjustment.

“Benchmark Replacement Adjustment” means the first alternative set forth in the order below that can be determined by the Calculation Agent as of the Benchmark Replacement Date:

(1) the spread adjustment, or method for calculating or determining such spread adjustment (which may be a positive or negative value or zero), that has been selected or recommended by the Relevant Governmental Body for the applicable Unadjusted Benchmark Replacement (as defined below);

(2) if the applicable Unadjusted Benchmark Replacement is equivalent to the ISDA Fallback Rate, then the ISDA Fallback Adjustment (as defined below); and

(3) the spread adjustment (which may be a positive or negative value or zero) that has been selected by the Calculation Agent giving due consideration to any industry-accepted spread adjustment or method for

S-24

TABLE OF CONTENTS

calculating or determining such spread adjustment, for the replacement of the then-current Benchmark with the applicable Unadjusted Benchmark Replacement for U.S. dollar-denominated floating rate securities at such time.

“Benchmark Replacement Conforming Changes” means, with respect to any Benchmark Replacement, any technical, administrative or operational changes (including changes to the definition of “Interest Period,” timing and frequency of determining rates with respect to each Interest Period and making payments of interest, rounding of amounts or tenors, and other administrative matters) that the Calculation Agent decides may be appropriate to reflect the adoption of such Benchmark Replacement in a manner substantially consistent with market practice (or, if the Calculation Agent decides that adoption of any portion of such market practice is not administratively feasible or if the Calculation Agent determines that no market practice for use of the Benchmark Replacement exists, in such other manner as the Calculation Agent determines is reasonably necessary).

“Benchmark Replacement Date” means the earliest to occur of the following events with respect to the then-current Benchmark:

(1) in the case of clause (1) of the definition of “Benchmark Transition Event,” the relevant Reference Time in respect of any determination;

(2) in the case of clause (2) or (3) of the definition of “Benchmark Transition Event,” the later of (a) the date of the public statement or publication of information referenced therein and (b) the date on which the administrator of the Benchmark permanently or indefinitely ceases to provide the Benchmark; or

(3) in the case of clause (4) of the definition of “Benchmark Transition Event,” the date of the public statement or publication of information referenced therein.

For the avoidance of doubt, for purposes of the definitions of Benchmark Replacement Date and Benchmark Transition Event, references to the Benchmark also include any reference rate underlying the Benchmark (for example, if the Benchmark becomes Compounded SOFR, references to the Benchmark would include SOFR).

For the avoidance of doubt, if the event giving rise to the Benchmark Replacement Date occurs on the same day as, but earlier than, the Reference Time in respect of any determination, the Benchmark Replacement Date will be deemed to have occurred prior to the Reference Time for such determination.

“Benchmark Transition Event” means the occurrence of one or more of the following events with respect to the then-current Benchmark:

(1) if the Benchmark is Three-Month Term SOFR, (a) the Relevant Governmental Body has not selected or recommended a forward-looking term rate for a tenor of three months based on SOFR, (b) the development of a forward-looking term rate for a tenor of three months based on SOFR that has been recommended or selected by the Relevant Governmental Body is not complete or (c) we determine that the use of a forward-looking rate for a tenor of three months based on SOFR is not administratively feasible;

(2) a public statement or publication of information by or on behalf of the administrator of the Benchmark announcing that such administrator has ceased or will cease to provide the Benchmark, permanently or indefinitely, provided that, at the time of such statement or publication, there is no successor administrator that will continue to provide the Benchmark;

(3) a public statement or publication of information by the regulatory supervisor for the administrator of the Benchmark, the central bank for the currency of the Benchmark, an insolvency official with jurisdiction over the administrator for the Benchmark, a resolution authority with jurisdiction over the administrator for the Benchmark or a court or an entity with similar insolvency or resolution authority over the administrator for the Benchmark, which states that the administrator of the Benchmark has ceased or will cease to provide

S-25

TABLE OF CONTENTS

the Benchmark permanently or indefinitely, provided that, at the time of such statement or publication, there is no successor administrator that will continue to provide the Benchmark; or

(4) a public statement or publication of information by the regulatory supervisor for the administrator of the Benchmark announcing that the Benchmark is no longer representative.

“Compounded SOFR” means the compounded average of SOFRs for the applicable Corresponding Tenor, with the rate, or methodology for this rate, and conventions for this rate being established by the Calculation Agent in accordance with:

(1) the rate, or methodology for this rate, and conventions for this rate selected or recommended by the Relevant Governmental Body for determining compounded SOFR; provided that:

(2) if, and to the extent that, the Calculation Agent determines that Compounded SOFR cannot be determined in accordance with clause (1) above, then the rate, or methodology for this rate, and conventions for this rate that have been selected by the Calculation Agent giving due consideration to any industry-accepted market practice for U.S. dollar-denominated floating rate securities at such time.

For the avoidance of doubt, the calculation of Compounded SOFR shall exclude the Benchmark Replacement Adjustment (if applicable) and the spread of basis points per annum.

“Corresponding Tenor” with respect to a Benchmark Replacement means a tenor (including overnight) having approximately the same length (disregarding business day adjustment) as the applicable tenor for the then-current Benchmark.

“Interpolated Benchmark” with respect to the Benchmark means the rate determined for the Corresponding Tenor by interpolating on a linear basis between: (1) the Benchmark for the longest period (for which the Benchmark is available) that is shorter than the Corresponding Tenor, and (2) the Benchmark for the shortest period (for which the Benchmark is available) that is longer than the Corresponding Tenor.

“ISDA” means the International Swaps and Derivatives Association, Inc. or any successor.

“ISDA Definitions” means the 2006 ISDA Definitions published by ISDA, as amended or supplemented from time to time, or any successor definitional booklet for interest rate derivatives published from time to time.

“ISDA Fallback Adjustment” means the spread adjustment (which may be a positive or negative value or zero) that would apply for derivatives transactions referencing the ISDA Definitions to be determined upon the occurrence of an index cessation event with respect to the Benchmark for the applicable tenor.

“ISDA Fallback Rate” means the rate that would apply for derivatives transactions referencing the ISDA Definitions to be effective upon the occurrence of an index cessation date with respect to the Benchmark for the applicable tenor excluding the applicable ISDA Fallback Adjustment.

“Unadjusted Benchmark Replacement” means the Benchmark Replacement excluding the Benchmark Replacement Adjustment.

The terms “FRBNY’s Website,” “Reference Time,” “Relevant Governmental Body,” “SOFR” and “Term SOFR” have the meanings set forth above under the heading “—Interest.”

Determinations and Decisions

The Calculation Agent is expressly authorized to make certain determinations, decisions and elections under the terms of the Notes, including with respect to the use of Three-Month Term SOFR as the Benchmark for the floating rate period and under the benchmark transition provisions. Any determination, decision or election that may be made by the Calculation Agent under the terms of the Notes, including any determination

S-26

TABLE OF CONTENTS

with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection:

•

will be conclusive and binding on the holders of the Notes and the Trustee absent manifest error;

•

if made by us as Calculation Agent, will be made in our sole discretion;

•

if made by a Calculation Agent other than us, will be made after consultation with us, and the Calculation Agent will not make any such determination, decision or election to which we reasonably object; and

•

notwithstanding anything to the contrary in the subordinated indenture, shall become effective without consent from the holders of the Notes, the Trustee or any other party.

Satisfaction and Discharge

We may discharge our obligations under the Indenture and the Notes if: (i) all outstanding Notes have been delivered for cancellation; (ii) all outstanding Notes have become due and payable or will become due and payable at their maturity date within one year; or (iii) all outstanding Notes are scheduled for redemption within one year, and we have irrevocably deposited with the Trustee an amount sufficient to pay and discharge the principal of (and premium, if any) and interest on all outstanding Notes and any other sums due on the maturity date or a redemption date. Then, upon our request, the Subordinated Indenture will cease to be of further effect, and we will be deemed to have satisfied and discharged the Subordinated Indenture with respect to the Notes. However, we will continue to be obligated to pay all other sums due under the Subordinated Indenture and to provide the officers’ certificates and opinions of counsel described in the Subordinated Indenture.

Further Issuances

We may from time to time, without notice to, or the consent of the holders of the Notes, create and issue further notes ranking equally with the Notes and with identical terms in all respects (or in all respects except for the offering price, the payment of interest accruing prior to the issue date of such further notes, or the first payment of interest following the issue date of such further notes), in order that such further notes may be consolidated and form a single series with the Notes and have the same terms as to status, redemption or otherwise as the Notes; provided, however, that a separate CUSIP number will be issued for any such additional notes unless the Notes are fungible for U.S. federal income tax purposes, subject to the procedures of DTC.

Consolidation, Merger and Sale of Assets

The Indenture provides that we may not consolidate with or merge into any other person or convey, transfer or lease our assets substantially as an entirety to any person, and we may not permit any other person to consolidate with or merge into us or to convey, transfer or lease our assets substantially as an entirety to us if, in such case, we are not the surviving entity, unless:

•

if we consolidate with or merge into any other person or convey, transfer or lease our assets substantially as an entirety to any other person, the person formed by such consolidation or into which we merge, or the person that acquires our assets, is a corporation, partnership, limited liability company or other entity organized or formed and validly existing under the laws of the United States of America, any of its states or the District of Columbia, which person must expressly assume, by a supplemental indenture, the due and punctual payment of the principal of and interest on the Notes and the performance or observance of our covenants under the Indenture;

•

immediately after giving effect to such transaction and treating any indebtedness that becomes an obligation of ours or our subsidiaries as a result of such transaction as having been incurred by us or such subsidiary at the time of such transaction, no event of default, and no event which, after notice or lapse of time or both, would become an event of default, shall have happened and be continuing; and

•

we have complied with our obligations to deliver certain documentation to the Trustee.

Form, Denomination, Transfer, Exchange and Book-Entry Procedures

The Notes will be issued only in fully registered form, without interest coupons. The Notes will be issued only in minimum denominations of $1,000 and any integral multiple of $1,000 in excess thereof. The Notes will not be issued in bearer form. The Notes sold in this offering will be issued only against payment in immediately available funds.

Global Notes

The Notes will be issued in the form of one or more registered notes in global form, without interest coupons (which we refer to as the “Global Notes”).

Upon issuance, each of the Global Notes will be deposited with the Trustee as custodian for DTC, and registered in the name of Cede & Co., as nominee of DTC.

Ownership of beneficial interests in each Global Note will be limited to persons who have accounts with DTC, or “DTC participants,” or persons who hold interests through DTC participants. We expect that under procedures established by DTC:

•

upon deposit of each Global Note with DTC’s custodian, DTC will credit portions of the principal amount of the Global Note to the accounts of the DTC participants designated by the underwriter; and

•

ownership of beneficial interests in each Global Note will be shown on, and transfer of ownership of those interests will be effected only through, records maintained by DTC (with respect to interests of DTC participants) and the records of DTC participants (with respect to other owners of beneficial interests in the Global Note).

Beneficial interests in the Global Notes may not be exchanged for Notes in physical, certificated form except in the limited circumstances described below.

Exchanges Among Global Notes

Beneficial interests in one Global Note may generally be exchanged for interests in another Global Note. A beneficial interest in a Global Note that is transferred to a person who takes delivery through another Global Note will, upon transfer, become subject to any transfer restrictions and other procedures applicable to beneficial interests in the other Global Note.

Trustee

U.S. Bank National Association will act as Trustee under the Indenture. From time to time, we, and some of our subsidiaries, may maintain deposit accounts and conduct other banking transactions, including lending transactions, with the Trustee in the ordinary course of business. Additionally, U.S. Bank National Association serves as trustee under one or more indentures involving our existing debt securities. Upon the occurrence of an event of default, or an event which, after notice or lapse of time or both, would become an event of default under the Notes, or upon the occurrence of a default under another indenture under which U.S. Bank National Association serves as trustee, the trustee may be deemed to have a conflicting interest with respect to the other debt securities as to which we are not in default for purposes of the Trust Indenture Act and, accordingly, may be required to resign as Trustee under the Indenture. In that event, we would be required to appoint a successor trustee.

Notices

Any notices required to be given to the holders of the Notes will be given to the Trustee.

Payment and Paying Agents

We will pay principal and interest on the Notes at the corporate trust office of the Trustee or at the office of any paying agent that we may designate. The Trustee will act as the initial paying agent.

TABLE OF CONTENTS

BOOK-ENTRY PROCEDURES AND SETTLEMENT

The Notes will be represented by one or more permanent global notes (collectively, the “global notes”), which will be deposited with, or on behalf of, The Depository Trust Company (“DTC”), or any successor thereto, and registered in the name of Cede & Co. (“Cede”), as nominee of DTC. Ownership of beneficial interests in the global notes will be limited to institutions that have accounts with DTC or its nominee (each, a “participant” and collectively, the “participants”) or persons that may hold interests through participants. Investors in the global notes that are not participants may hold their interests indirectly through organizations (including Euroclear Bank S.A./N.V., as operator of the Euroclear System (“Euroclear”), and Clearstream Banking, société anonyme (“Clearstream”)) that are participants in such systems. Euroclear and Clearstream will hold interests in global notes on behalf of their participants through their respective depositaries, which in turn will hold such interests in global notes in customers’ securities accounts in the depositaries’ names on the books of DTC.

Beneficial ownership of the global notes by persons that hold through participants will only be evidenced by, and transfers of such ownership interests within such participants will be effected only through, records maintained by such participants. Except as provided below, owners of beneficial interests in the global notes: (1) will not be entitled to have Notes represented by the global notes registered in their names; (2) will not receive or be entitled to receive physical, certificated Notes; and (3) will not be considered the owners or holders of the Notes under the Indenture for any purpose, including with respect to the giving of any direction, instruction or approval to the Trustee under the Indenture.

As a result, each investor who owns a beneficial interest in the global notes must rely on the procedures of DTC to exercise any rights of a holder of Notes under the Indenture (and, if the investor is not a participant or an indirect participant in DTC, on the procedures of the DTC participant through which the investor owns its interest).

The laws of some jurisdictions require that certain purchasers of securities take physical delivery of such securities in definitive form. Such laws may impair the ability to hold or transfer your beneficial interests in the global notes. Because DTC can act only on behalf of its participants, which in turn act on behalf of indirect participants and certain banks, your ability to pledge your interests in the global notes to persons or entities that do not participate in the DTC system, or otherwise take actions in respect of such interests, may be affected by the lack of a physical certificate evidencing such interests.

The Company has been advised by DTC that upon issuance of a global note or global notes and the deposit of such global note or global notes with DTC, DTC will immediately credit on its book-entry registration and transfer system the respective principal amounts of the Notes represented by such global note or global notes to the accounts of participants. Each owner of a beneficial interest in a global note is required to hold at all times a beneficial interest in a $1,000 principal amount or any integral multiple of $1,000 in excess thereof of such global note.

Principal and interest payments on the Notes registered in the name of DTC or its nominee will be made by the Trustee to DTC or its nominee, as the case may be, as the registered owner and holder of the global note or global notes. Such payments to DTC or its nominee, as the case may be, will be made in immediately available funds, provided that in the case of payments of principal and interest on the maturity date, the global note or global notes are presented to the Trustee in time for the Trustee to make such payments in such funds in accordance with its normal procedures. Under the terms of the Indenture, the Company and the Trustee will treat the persons in whose names the Notes are registered as the owners of such Notes for the purpose of receiving payment of principal and interest on such Notes and for all other purposes. Neither the Company nor the Trustee has any responsibility or liability for the payment of amounts to owners of beneficial interests in the global notes, for any aspect of the records relating to or payments made on account of beneficial interests in the global notes or for maintaining, supervising or reviewing any records relating to such beneficial interests.

DTC has advised the Company and the Trustee that upon receipt of any payment of principal or interest in respect of a global note it will immediately credit the accounts of participants with payments in amounts

S-30

TABLE OF CONTENTS

proportionate to their respective beneficial interests in the principal amount of such global note or global notes as shown on the records of DTC or its nominee, unless DTC has reason to believe that it will not receive payment on that payment date. Payments by participants to owners of beneficial interests in the global notes held through such participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in “street names,” and will be the responsibility of such participants or indirect participants.

Transfers between participants in DTC will be effected under DTC’s procedures and will be settled in same day funds. Transfers between participants in Euroclear and Clearstream will be effected in the ordinary way in accordance with their respective rules and operating procedures.

Cross-market transfers between DTC, on the one hand, and directly or indirectly through Euroclear or Clearstream participants, on the other, will be effected by DTC in accordance with DTC’s rules on behalf of Euroclear or Clearstream, as the case may be, by its respective depositary; however, such cross-market transactions will require delivery of instructions to Euroclear or Clearstream, as the case may be, by the counterparty in such system in accordance with its rules and procedures and within its established deadlines (Brussels time). Euroclear or Clearstream, as the case may be, will, if the transaction meets its settlement requirements, deliver instructions to its respective depositary to take action to effect final settlement on its behalf by delivering or receiving interests in global notes in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Euroclear participants and Clearstream participants may not deliver instructions directly to the depositories for Euroclear or Clearstream.

As a result of the time zone differences, the securities account of a Euroclear or Clearstream participant purchasing an interest in global notes from a DTC participant will be credited during the securities settlement processing day (which must be a business day for Euroclear or Clearstream, as the case may be) immediately following DTC’s settlement date, and such credit of any transaction’s interests in global notes settled during such processing day will be reported to the relevant Euroclear or Clearstream participant on such day. Cash received in Euroclear or Clearstream as a result of sales of interests in global notes by or through a Euroclear or Clearstream participant to DTC participant will be received with value on DTC’s settlement date, but will be available in the relevant Euroclear or Clearstream cash account only as of the business day following settlement in DTC.

Although the Company expects that DTC, Euroclear and Clearstream will follow the foregoing procedures in order to facilitate transfers of interests in global notes among participants of DTC, Euroclear and Clearstream, DTC, Euroclear and Clearstream are under no obligation to perform or continue to perform such procedures, and such procedures may be discontinued at any time. Neither the Company nor the Trustee will have any responsibility for the performance by DTC, Euroclear or Clearstream or their participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

Participants and owners of beneficial interests in the global notes will not be entitled to receive Notes in definitive form and will not be considered holders of the Notes unless (i) DTC notifies the Company in writing that it is unwilling or unable to act as a depository or if DTC ceases to be a clearing agency registered under the Exchange Act and a successor depositary is not appointed by the Company within 90 days, (ii) the Company, at its option, notifies the Trustee in writing that it elects to cause the issuance of Notes in definitive form or (iii) any event shall have happened and be continuing that, after notice or lapse of time or both, would constitute an Event of Default with respect to the Notes. In such circumstances, upon surrender by DTC or a successor depositary of the global notes, Notes in definitive form will be issued to each person that DTC or a successor depositary identifies as the beneficial owner of the related Notes. Upon such issuance, the Trustee is required to register such Notes in the name or names of, and cause the same to be delivered to, such person or persons (or the nominee thereof). Such Notes would be issued in fully registered form without coupons in denominations of $1,000 and integral multiples of $1,000 in excess thereof. Such Notes may not subsequently be exchanged by a holder for Notes in denominations of less than $1,000, and will contain a legend stating that each such Note is issuable in a minimum denomination of $1,000 and may not be exchanged for securities of the Company with a smaller denomination.

TABLE OF CONTENTS

Except as provided above, beneficial owners of global notes will not be entitled to receive physical delivery of Notes in definitive form and no global note will be exchangeable except for another global note of like denomination and tenor to be registered in the name of DTC or its nominee. Accordingly, each person owning a beneficial interest in a global note must rely on the procedures of DTC and, if such person is not a participant, on the procedures of the participant through which such person owns its interest, to exercise any rights of a holder under the Notes. The Company understands that under existing industry practices, if the Company requests any action of holders of the Notes or any holder of beneficial interests in a global note desires to give or take any action a holder of the Notes is entitled to give or take under the terms of the Notes, DTC would authorize the participants owning the relevant beneficial interests to give or take such action, and such participants would authorize the beneficial owners owning through such participants to give or taken such action or would otherwise act upon the instructions of the beneficial owners owning through them.

Notes in physical, certificated form will be issued and delivered to each person that DTC identifies as a beneficial owner of the related Notes only if: (1) DTC notifies us at any time that it is unwilling or unable to continue as depositary for the global notes and a successor depositary is not appointed within 120 days; (2) DTC ceases to be registered as a clearing agency under the Exchange Act and a successor depositary is not appointed within 120 days; (3) we, at our option, notify the Trustee that we elect to cause the issuance of certificated notes; or (4) an event of default shall have occurred and be continuing with respect to the Notes and the Trustee has received a written request from DTC to issue the Notes in certificated form.

DTC has advised us that DTC is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered pursuant to Section 17A of the Exchange Act. DTC holds and provides asset servicing for millions of issues of U.S. and non-U.S. equity issues, corporate and municipal debt issues, and money market instruments that its participants (“Direct Participants”) deposit with DTC. DTC also facilitates the post-trade settlement among Direct Participants of sales and other securities transactions in deposited securities, through electronic computerized book-entry transfers and pledges between Direct Participants’ accounts. This eliminates the need for physical movement of securities certificates. Direct Participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the depository system is also available to others such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies and clearing corporations that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly. Investors who are not Direct Participants or indirect participants in DTC may beneficially own securities held by, or on behalf of, DTC only through Direct Participants or indirect participants in DTC. The rules applicable to DTC’s participants are on file with the SEC. More information about DTC can be found at www.dtcc.com and www.dtc.org.

The information in this section concerning DTC and its book-entry system, as well as information regarding Euroclear and Clearstream, has been obtained from sources that the Company believes to be reliable, but the Company takes no responsibility for its accuracy or completeness. We provide this information solely for the convenience of investors. The policies and procedures of DTC, which may change periodically, will apply to payments, transfers, exchanges and other matters relating to beneficial interests in the global note. We and the paying agent have no responsibility or liability for any aspect of DTC’s or any participants’ records relating to beneficial interests in the global note, including for payments made on the global note, and we are not responsible for maintaining, supervising or reviewing any of those records. Additionally, neither we nor the underwriter are responsible for the operations and procedures of DTC, Euroclear or Clearstream.

Clearstream has advised us that it is incorporated under the laws of Luxembourg as a bank. Clearstream holds securities for its participating organizations (“Clearstream participants”) and facilitates the clearance and settlement of securities transactions between Clearstream participants through electronic book-entry changes in accounts of Clearstream participants, thereby eliminating the need for physical movement of certificates. Clearstream provides to its participants, among other things, services for safekeeping,

S-32

TABLE OF CONTENTS

administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Clearstream interacts with domestic securities markets in over 30 countries through established depository and custodial relationships. As a bank, Clearstream is subject to regulation by the Luxembourg Commission for the Supervision of the Financial Sector (Commission de Surveillance du Secteur Financier) and the Banque Centrale du Luxembourg. Clearstream participants are financial institutions recognized around the world and include underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations, and may include the underwriters. Clearstream’s U.S. customers are limited to securities brokers and dealers and banks. Indirect access to Clearstream is also available to others, such as banks, brokers, dealers and trust companies, that clear through or maintain a custodial relationship with a Clearstream participant either directly or indirectly.

Euroclear has advised us that it was created in 1968 to hold securities for its participants and to clear and settle transactions between its participants and between its participants and participants of certain other securities intermediaries through simultaneous electronic book-entry delivery against payment, thereby eliminating the need for physical movement of certificates and any risk from lack of simultaneous delivery of securities and cash. Euroclear provides various other services, including securities lending and borrowing, and interacts with domestic markets in several countries. Euroclear participants include banks (including central banks), securities brokers and dealers and other professional financial intermediaries, supranationals, custodians, investment managers, corporations, trust companies and certain other organizations, and may include the underwriters. Indirect access to Euroclear is also available to others that clear through or maintain a custodial relationship with a Euroclear participant, either directly or indirectly.

Distributions with respect to Notes held beneficially through Euroclear will be credited to the cash accounts of Euroclear participants in accordance with the terms and conditions governing use of Euroclear, when received by the U.S. depositary for Euroclear. Euroclear has further advised the Bank that investors that acquire, hold and transfer interests in the Notes by book-entry through accounts with Euroclear or any securities intermediary are subject to the laws and contractual provisions governing their relationship with their intermediary, as well as the laws and contractual provisions governing the relationship between such an intermediary and each other intermediary, if any, standing between themselves and the global notes.

Euroclear has advised us that under Belgian law, investors which are credited with securities on the records of Euroclear have a co-proprietary right in the fungible pool of interests in securities on deposit with Euroclear in an amount equal to the amount of interests in securities credited to their accounts. In the event of the insolvency of Euroclear, Euroclear participants would have a right under Belgian law to the return of the amount and type of interests in securities credited to their accounts with Euroclear. If Euroclear did not have a sufficient amount of interests in securities on deposit of a particular type to cover the claims of all participants credited with such interests in securities on Euroclear’s records, all participants having an amount of interests in securities of such type credited to their accounts with Euroclear would then have the right under Belgian law only to the return of their pro rata share of the amount of interests in securities actually on deposit.

Under Belgian law, Euroclear is required to pass on the benefits of ownership in any interests in securities on deposit with it (such as dividends, voting rights and other entitlements) to any person credited with such interest in securities on its records.

Clearance and Settlement

Initial settlement for the Notes will be made in immediately available funds. The Notes will trade in DTC’s Same-Day Funds Settlement System until maturity and, therefore, DTC will require secondary trading activity in the Notes to be settled in immediately available funds. Secondary trading in long-term notes and debentures of corporate issuers is generally settled in clearing house or next-day funds. We make no representations as to the effect that settlement in immediately available funds will have on trading activity in those beneficial interests.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

The following is a general discussion of the material U.S. federal income tax considerations applicable to U.S. holders and non-U.S. holders (each as defined below) with respect to the ownership and disposition of the Notes acquired in this offering, but it does not purport to be a complete analysis of all the potential tax considerations. This discussion is limited to the U.S. federal income tax consequences relevant to holders that acquire Notes in the initial offering at their original “issue price” and hold them as “capital assets” within the meaning of Section 1221 of the U.S. Internal Revenue Code of 1986, as amended (the “Code”) (generally, property held for investment). This discussion does not address tax consequences relevant to subsequent purchasers of the Notes. This discussion is based on current provisions of the Code, the Treasury Regulations promulgated thereunder, judicial decisions and administrative rulings and published positions of the Internal Revenue Service (the “IRS”), each as in effect as of the date hereof and all of which are subject to change or differing interpretations, possibly with retroactive effect, and any such change or interpretation could affect the accuracy of the statements and conclusions set forth herein.

This discussion is for general information only and does not purport to address all aspects of U.S. federal income taxation that may be relevant to particular holders in light of their particular circumstances and does not apply to holders subject to special rules under the U.S. federal income tax laws (including, for example, banks or other financial institutions, dealers in securities or currencies, traders in securities that elect to apply a mark-to-market method of accounting, insurance companies, tax-exempt entities, grantor trusts, entities or arrangements treated as partnerships for U.S. federal income tax purposes or other flow-through entities (and investors therein), subchapter S corporations, retirement plans, individual retirement accounts or other tax-deferred accounts, real estate investment trusts, regulated investment companies, holders liable for the alternative minimum tax, certain former citizens or former long-term residents of the United States, U.S. holders having a “functional currency” other than the U.S. dollar, holders who hold Notes as part of a hedge, straddle, constructive sale, conversion transaction or other integrated transaction, “controlled foreign corporations,” “passive foreign investment companies,” and persons required to accelerate the recognition of any item of gross income with respect to the Notes as a result of such income being recognized on an applicable financial statement). This discussion also does not address any considerations under U.S. federal tax laws other than those pertaining to the income tax, nor does it address any considerations under any state, local or non-U.S. tax laws. In addition, this discussion does not address the tax consequences of the ownership and disposition of the Notes arising under the unearned income Medicare contribution tax pursuant to the Health Care and Education Reconciliation Act of 2010. Prospective investors should consult with their own tax advisors as to the particular tax consequences to them of the ownership and disposition of the Notes, including with respect to the applicability and effect of any U.S. federal, state, local or non-U.S. income tax laws or any tax treaty, and any changes (or proposed changes) in tax laws or interpretations thereof.

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds Notes, the tax treatment of a person treated as a partner in such partnership generally will depend on the status of the partner and the activities of the partnership. Persons that for U.S. federal income tax purposes are treated as partners in any partnership holding Notes should consult their own tax advisors regarding the tax consequences of the ownership and disposition of Notes.

THIS DISCUSSION IS FOR GENERAL INFORMATION PURPOSES ONLY AND IS NOT INTENDED TO CONSTITUTE A COMPLETE DESCRIPTION OF ALL TAX CONSEQUENCES RELATING TO THE OWNERSHIP AND DISPOSITION OF THE NOTES. PROSPECTIVE INVESTORS SHOULD CONSULT THEIR OWN TAX ADVISORS AS TO THE PARTICULAR TAX CONSEQUENCES TO THEM OF THE OWNERSHIP AND DISPOSITION OF THE NOTES, INCLUDING WITH RESPECT TO THE APPLICABILITY AND EFFECT OF ANY U.S. FEDERAL, STATE, LOCAL OR NON-U.S. INCOME TAX LAWS OR ANY TAX TREATY.

The terms of the Notes provide for payments by us prior to their scheduled payment dates under certain circumstances (see “Description of the Notes—Redemption”). The possibility of such payments may implicate special rules under Treasury Regulations governing “contingent payment debt instruments.” According to those Treasury Regulations, the possibility that such payments of accelerated amounts will be made will not affect the amount of income a holder recognizes in advance of the payment of such accelerated amounts if

S-34

TABLE OF CONTENTS

there is only a remote chance as of the date the Notes are issued that such payments will be made. We intend to take the position that the likelihood that such payments will be made is remote within the meaning of the applicable Treasury Regulations. Our position that these contingencies are remote is binding on a holder unless such holder discloses its contrary position to the IRS in the manner required by applicable Treasury Regulations. Our position is not, however, binding on the IRS, and if the IRS were to challenge this position successfully, a holder might be required to, among other things, accrue interest income based on a projected payment schedule and comparable yield, which may be in excess of stated interest, and treat as ordinary income rather than capital gain any income realized on the taxable disposition of a Note. In the event a contingency described above occurs, it could affect the amount, timing and character of the income or loss recognized by a holder. Prospective holders should consult their own tax advisors regarding the tax consequences if the Notes were treated as contingent payment debt instruments. The remainder of this discussion assumes that the Notes will not be considered contingent payment debt instruments.

U.S. Holders

For purposes of this discussion, the term “U.S. holder” means a beneficial owner of a Note that is, for U.S. federal income tax purposes:

•

an individual who is a citizen or resident of the United States;

•

a corporation (or any other entity or arrangement treated as a corporation for U.S. federal income tax purposes) created or organized under the laws of the United States, any state thereof, or the District of Columbia or any other corporation treated as a domestic corporation;

•

an estate, the income of which is subject to U.S. federal income tax regardless of its source; or

•

a trust (a) if a court within the United States is able to exercise primary supervision over the trust’s administration and one or more U.S. persons have the authority to control all substantial decisions of the trust or (b) that was in existence on August 20, 1996 and has a valid election in effect under applicable Treasury Regulations to be treated as a U.S. person for U.S. federal income tax purposes.

Payments of Stated Interest

It is anticipated, and this discussion assumes, that the issue price of the Notes will be equal to the stated principal amount or, if the issue price is less than the stated principal amount, the difference will be a de minimis amount (as set forth in the applicable Treasury Regulations). Accordingly, stated interest on a Note generally will be taxable to a U.S. holder as described below under “—Qualified Stated Interest.”

If, however, the issue price of a Note is less than the stated redemption amount at maturity and the difference is more than a de minimis amount (as set forth in the applicable Treasury Regulations), then a U.S. holder generally will be required to include the difference in income as original issue discount as it accrues in accordance with a constant yield method. U.S. holders should consult their tax advisors as to the consequences to them if the Notes are issued with original issue discount.

Variable Rate Debt Instruments

The Notes will initially bear interest at a fixed annual rate. From and including , 2026 to but excluding the maturity date or earlier redemption date, the Notes will bear interest at an annual floating rate equal to the Benchmark rate, which is expected to be Three-Month Term SOFR, as determined for the applicable Interest Period plus a spread of basis points payable quarterly in arrears on , , and of each year, commencing on , 2027. Under applicable Treasury Regulations, a debt instrument will qualify as a “variable rate debt instrument” if (a) its issue price does not exceed the total noncontingent principal payments due under the debt instrument by more than a specified de minimis amount, (b) the debt instrument does not provide for any stated interest other than stated interest, paid or compounded at least annually, at current value of (i) one or more “qualified floating rates,” (ii) a single fixed rate and one or more qualified floating rates, (iii) a “single objective rate,” or (iv) a single fixed rate and a single objective rate that is a “qualified inverse floating rate,” (c) the debt instrument provides that

S-35

TABLE OF CONTENTS

a qualified floating rate or objective rate in effect at any time during the term of the instrument is set at a current value of that rate, and (d) except as described in (a) above, does not provide for any principal payments that are contingent. A “qualified floating rate” is any variable rate where variations in the value of such rate can reasonably be expected to measure contemporaneous variations in the cost of newly borrowed funds in the currency in which the debt instrument is denominated. Under the foregoing definition, the Notes are expected to be treated as variable rate debt instruments for U.S. federal income tax purposes and the discussion below is based on this assumption.

Qualified Stated Interest

The tax treatment of interest paid on the Notes depends on whether such interest constitutes “qualified stated interest,” referred to herein as “QSI.” Interest is QSI if it is unconditionally payable or will be constructively received, in cash or property, at least annually at a single fixed rate or at a single “qualified floating rate” or “objective rate” (each as defined in the applicable Treasury regulations) that qualifies under the variable rate debt instrument rules. The amount of qualified stated interest on variable rate debt instruments providing for interest other than at a single qualified floating rate or single objective rate, such as the Notes, is determined pursuant to special rules discussed further under “Determination of Interest Accruals on the Notes” below. Interest that is QSI will generally be includible in a U.S. holder’s income as ordinary interest income at the time such interest payments are accrued or received, depending on the U.S. holder’s regular method of accounting for U.S. federal income tax purposes. Interest that is not QSI is generally includible in a U.S. holder’s income under the rules governing original issue discount, regardless of such U.S. holder’s method of accounting.

Determination of Interest Accruals on the Notes. Under applicable Treasury Regulations, in order to determine the amount of QSI in respect of the Notes, an equivalent fixed rate debt instrument must be constructed. The equivalent fixed rate debt instrument is a hypothetical instrument that has terms that are identical to those of the Notes, except that the equivalent fixed rate debt instrument provides for fixed rate substitutes in lieu of the actual rates on the Notes. The equivalent fixed rate debt instrument is constructed in the following fashion: (i) first, the initial fixed rate is replaced with a qualified floating rate such that the fair market value of the Notes as of the Notes’ issue date would be approximately the same as the fair market value of an otherwise identical debt instrument that provides for the replacement qualified floating rate rather than the fixed rate, and (ii) second, each floating rate (including the floating rate determined under (i) above) is converted into a fixed rate substitute (which, in each case, generally will be the value of each floating rate as of the issue date of the Notes).

Once the equivalent fixed rate debt instrument has been constructed pursuant to the foregoing rules, the amount of QSI, if any, is determined for the equivalent fixed rate debt instrument by applying the general QSI rules to the equivalent fixed rate debt instrument, and a U.S. holder of the Notes will account for such QSI as if the U.S. holder held the equivalent fixed rate debt instrument.

For each accrual period, appropriate adjustments will be made to the amount of QSI assumed to have been accrued or paid with respect to the “equivalent” fixed rate debt instrument in the event that such amounts differ from the actual amount of interest accrued or paid on the Notes during the accrual period.

Based upon current market conditions and the manner in which the interest rates on the Notes are determined, we expect that the equivalent fixed rate debt instrument (as determined in the manner described above) would be treated as having a single fixed interest rate throughout the term of the Notes for purposes of calculating QSI. Accordingly, solely for purposes of determining QSI, as of the issue date of the Notes, we expect that the Notes will be presumed to remain outstanding until maturity, all interest on the Notes will be treated as QSI and the Notes will not be treated as having been issued with any original issue discount.

Sale, Exchange, Redemption or Other Taxable Disposition of the Notes

A U.S. holder generally will recognize gain or loss upon the sale, exchange, redemption or other taxable disposition of a Note equal to the difference, if any, between (a) the sum of the cash and the fair market value of any property received on such disposition (other than amounts properly attributable to accrued but unpaid

S-36

TABLE OF CONTENTS

interest, which amounts will be treated as interest income as described above under “—Payments of Stated Interest”) and (b) such U.S. holder’s adjusted tax basis in the Note. A U.S. holder’s adjusted tax basis in a Note generally will be equal to the amount that such U.S. holder paid for the Note. Any gain or loss recognized on a sale, exchange, redemption or other taxable disposition of a Note generally will be capital gain or loss, and will be long-term capital gain or loss, if, at the time of such disposition, the U.S. holder will have held the Note for a period of more than one year. Long-term capital gains recognized by certain noncorporate U.S. holders (including certain individuals) generally are subject to preferential tax rates. The deductibility of capital losses is subject to limitations.

Information Reporting and Backup Withholding

Information reporting generally will apply to payments of interest on the Notes and to the proceeds of a sale or other taxable disposition of a Note paid to a U.S. holder unless the U.S. holder is an exempt recipient. U.S. federal backup withholding (currently, at a rate of 24% for payments made before January 1, 2026) generally will apply to such payments if the U.S. holder fails to provide the applicable withholding agent with a properly completed and executed IRS Form W-9 providing such U.S. holder’s correct taxpayer identification number and certifying that such U.S. holder is not subject to backup withholding, or to otherwise establish an exemption.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against a U.S. holder’s U.S. federal income tax liability, if any, provided that the required information is furnished timely to the IRS.

Non-U.S. Holders

For purposes of this discussion, the term “non-U.S. holder” means a beneficial owner of a Note that is neither a U.S. holder nor a partnership for U.S. federal income tax purposes.

Payments of Stated Interest

Subject to the discussion below under “—Information Reporting and Backup Withholding,” payments of interest on the Notes to a non-U.S. holder generally will not be subject to U.S. federal income or withholding tax under the “portfolio interest exemption,” provided that:

•

such interest is not effectively connected with the non-U.S. holder’s conduct of a trade or business within the United States (or, in the case of an income tax treaty resident, is not attributable to a permanent establishment of the non-U.S. holder in the United States);

•

the non-U.S. holder does not actually or constructively own 10% or more of the total combined voting power of all classes of our stock entitled to vote within the meaning of the Code and applicable Treasury Regulations;

•

the non-U.S. holder is not a “controlled foreign corporation” with respect to which we are a “related person” within the meaning of the Code; and

•

either (a) the beneficial owner of the Notes provides the applicable withholding agent with a properly completed and executed IRS Form W-8BEN or IRS Form W-8BEN-E, as applicable, certifying, under penalties of perjury, that it is not a “U.S. person” (as defined in the Code) and providing its name and address or (b) a financial institution that holds the Notes on behalf of the beneficial owner certifies to the applicable withholding agent, under penalties of perjury, that it has received such properly completed and executed IRS Form W-8BEN or IRS Form W-8BEN-E, as applicable, from the beneficial owner and provides the applicable withholding agent with a copy thereof.

If a non-U.S. holder cannot satisfy the requirements of the “portfolio interest exemption” described above, payments of interest made to the non-U.S. holder generally will be subject to U.S. federal withholding tax at a rate of 30%, or such lower rate as may be specified by an applicable income tax treaty, unless such interest is effectively connected with such non-U.S. holder’s conduct of a trade or business within the United

S-37

TABLE OF CONTENTS

States (and, if required by an applicable income tax treaty, is attributable to a permanent establishment of the non-U.S. holder in the United States) and such non-U.S. holder provides the applicable withholding agent with a properly completed and executed IRS Form W-8ECI (or other applicable IRS form). In order to claim an exemption from or reduction of withholding under an applicable income tax treaty, a non-U.S. holder generally must furnish to the applicable withholding agent a properly executed IRS Form W-8BEN or IRS Form W-8BEN-E, as applicable (or other applicable IRS form). Non-U.S. holders eligible for an exemption from or reduced rate of U.S. federal withholding tax under an applicable income tax treaty may obtain a refund of any excess amounts withheld by timely filing an appropriate claim with the IRS. Non-U.S. holders should consult their own tax advisors regarding their entitlement to benefits under an applicable income tax treaty and the requirements for claiming any such benefits.

Interest paid to a non-U.S. holder that is effectively connected with such non-U.S. holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, is attributable to a permanent establishment of the non-U.S. holder in the United States) generally will not be subject to U.S. federal withholding tax, provided that the non-U.S. holder complies with applicable certification and other requirements. Instead, such interest generally will be subject to U.S. federal income tax on a net income basis and at the regular graduated U.S. federal income tax rates in the same manner as if such non-U.S. holder were a U.S. person. A non-U.S. holder that is a corporation may be subject to an additional “branch profits tax” at a rate of 30% (or such lower rate as may be specified by an applicable income tax treaty) of its “effectively connected earnings and profits” for the taxable year, subject to certain adjustments.

Sale, Exchange, Redemption or Other Taxable Disposition of the Notes

Subject to the discussion below under “—Information Reporting and Backup Withholding,” except with respect to accrued and unpaid interest (which will be treated as described above under “—Non-U.S. Holders—Payments of Stated Interest”), a non-U.S. holder generally will not be subject to U.S. federal income tax or withholding tax on any gain realized upon the sale, exchange, redemption or other taxable disposition of a Note unless:

•

such gain is effectively connected with the non-U.S. holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, is attributable to a permanent establishment of the non-U.S. holder in the United States); or

•

the non-U.S. holder is an individual who is present in the United States for 183 days or more in the taxable year of the disposition and certain other conditions are met.

Gain described in the first bullet point above generally will be subject to U.S. federal income tax on a net income basis at the regular graduated U.S. federal income tax rates in the same manner as if such non-U.S. holder were a U.S. person. A non-U.S. holder that is a corporation also may be subject to an additional “branch profits tax” at a rate of 30% (or such lower rate as may be specified by an applicable income tax treaty) of its “effectively connected earnings and profits” for the taxable year, subject to certain adjustments.

Gain described in the second bullet point above generally will be subject to U.S. federal income tax at a 30% rate (or such lower rate as may be specified by an applicable income tax treaty), but may be offset by U.S. source capital losses, if any, of the non-U.S. holder.

Information Reporting and Backup Withholding

Generally, we must report annually to the IRS and to each non-U.S. holder the amount of interest paid to such non-U.S. holder and the amount of tax, if any, withheld with respect to such payments. These reporting requirements apply regardless of whether withholding was reduced or eliminated by an applicable income tax treaty. This information may also be made available to the tax authorities in the country in which a non-U.S. holder resides or is established pursuant to the provisions of a specific treaty or agreement with those tax authorities.

U.S. backup withholding tax (currently, at a rate of 24% for payments made before January 1, 2026) is imposed on certain payments to persons that fail to furnish the information required under the U.S.

S-38

TABLE OF CONTENTS

information reporting rules. Interest paid to a non-U.S. holder generally will be exempt from backup withholding if the non-U.S. holder provides the applicable withholding agent with a properly executed IRS Form W-8BEN or IRS Form W-8BEN-E, as applicable, or otherwise establishes an exemption.

Under Treasury Regulations, the payment of proceeds from the disposition of a Note by a non-U.S. holder effected at a U.S. office of a broker generally will be subject to information reporting and backup withholding, unless the non-U.S. holder provides a properly executed IRS Form W-8BEN or IRS Form W-8BEN-E, as applicable (or other applicable IRS Form W-8), certifying such non-U.S. holder’s non-U.S. status or by otherwise establishing an exemption. The payment of proceeds from the disposition of Notes by a non-U.S. holder effected at a non-U.S. office of a U.S. broker or a non-U.S. broker with certain specified U.S. connections generally will be subject to information reporting (but not backup withholding) unless such non-U.S. holder provides a properly executed IRS Form W-8BEN or IRS Form W-8BEN-E, as applicable (or other applicable IRS Form W-8), certifying such non-U.S. holder’s non-U.S. status or by otherwise establishing an exemption. Backup withholding will apply if the disposition is subject to information reporting and the broker has actual knowledge that the non-U.S. holder is a U.S. person.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against a non-U.S. holder’s U.S. federal income tax liability, if any, provided that the required information is furnished timely to the IRS. Non-U.S. Holders should consult their own tax advisors regarding the application of these rules to their particular circumstances.

Foreign Account Tax Compliance Act

Under Sections 1471 through 1474 of the Code and the Treasury regulations and administrative guidance thereunder (collectively, “FATCA”), a 30% withholding tax generally may be imposed on (1) interest on a debt obligation and (2) gross proceeds from the disposition of a debt obligation paid to certain non-U.S. entities (whether such non-U.S. entity is the beneficial owner of the obligation or an intermediary) that fail to comply with certain certification, withholding, and information reporting requirements (which may include entering into an agreement with the IRS) or otherwise satisfying the requirements of an applicable FATCA intergovernmental agreement.

Under the applicable Treasury regulations and administrative guidance, withholding under FATCA generally applies to payments of interest on the Notes. While withholding under FATCA would have applied also to payments of gross proceeds from the sale or other disposition of a Note on or after January 1, 2019, proposed Treasury regulations eliminate FATCA withholding on payments of gross proceeds entirely. Taxpayers generally may rely on these proposed Treasury regulations until final regulations are issued.

Purchasers of the Notes are urged to consult their own tax advisors regarding the effect, if any, of FATCA based on their particular circumstances.

THE U.S. FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE AS TO BOTH U.S. HOLDERS AND NON-U.S. HOLDERS IS INCLUDED FOR GENERAL INFORMATION ONLY AND MAY NOT BE APPLICABLE DEPENDING UPON A PURCHASER’S PARTICULAR SITUATION. PURCHASERS ARE URGED TO CONSULT THEIR TAX ADVISORS CONCERNING THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATION, AS WELL AS ANY TAX CONSEQUENCES UNDER OTHER FEDERAL TAX LAWS (SUCH AS ESTATE AND GIFT TAX LAWS) AND THE LAWS OF ANY FOREIGN, STATE, LOCAL OR OTHER TAXING JURISDICTIONS OR THE CONSEQUENCES ARISING UNDER ANY TAX TREATY.

BENEFIT PLAN INVESTOR CONSIDERATIONS

The Employee Retirement Income Security Act of 1974, as amended (“ERISA”), impose certain requirements on employee benefit plans within the meaning of Section 3(3) of ERISA subject Title I of ERISA (“ERISA Plans”) and Section 4975 of the Code also imposes certain requirements on ERISA Plans, as well as on individual retirement accounts (“IRAs”), Keogh plans or other plans and arrangements subject to Section 4975 of the Code. Entities (including certain insurance company general accounts) whose underlying assets include “plan assets” (as defined in U.S. Department of Labor regulation 29 C.F.R. Section 2510.3-101, as modified by Section 3(42) of ERISA (the “plan asset regulations”)) by reason of any such plan’s or arrangement’s investment therein are also subject to these requirements under Part 4 of Subtitle B of Tile I of ERISA and Section 4975 of the Code. We refer to the foregoing in this paragraph collectively as “Plans”. Under ERISA and Section 4975 of the Code, any person who exercises any discretionary authority or control over the administration of the Plan or the management or disposition of the assets of the Plan, or who renders investment advice for a fee or other compensation to the Plan, is generally considered to be a fiduciary of the Plan, and ERISA and Section 4975 of the Code also impose requirements on fiduciaries with respect to Plans. In addition, certain governmental, church and non-U.S. plans (“Non-ERISA Arrangements”) are not subject to ERISA or Section 4975 of the Code but may be subject to other laws that are substantially similar to ERISA and Section 4975 of the Code (each, a “Similar Law”).

The following summarizes certain aspects of ERISA, the Code and Similar Laws that may affect a decision by Plans or Non-ERISA Arrangements to invest in the Notes. The following discussion is general in nature and not intended to be a complete discussion of the applicable laws pertaining to a Plan’s or Non-ERISA Arrangement’s decision to invest and is not intended to be legal advice. In addition, the following discussion is based on the applicable law and regulations in effect as of the date of this prospectus supplement, and nothing herein shall be construed as an obligation to update this summary as a result of any changes in the applicable law or regulations. Fiduciaries of any Plans and Non-ERISA Arrangements should consult their own legal counsel before purchasing the Notes. References herein to the purchase, holding or disposition of Notes also refer to the purchase, holding or disposition of any beneficial interest in the Notes.

A Plan fiduciary should consider whether an investment in the Notes would be consistent with the fiduciary’s obligations under applicable laws, including common law, ERISA and the Code and the applicable regulations and guidance issued thereunder, including, to the extent applicable, the requirements that (a) the investment satisfy the prudence and diversification standards of ERISA, (b) the investment be solely in the interests of the participants and beneficiaries of the Plan, (c) the investment be permissible under the terms of the Plan’s investment policies and governing instruments, and (d) the investment be for the exclusive purpose of providing benefits to the participants and beneficiaries of the Plan and defraying the reasonable expenses of administering the Plan. In determining whether an investment in the Notes (or making such investment available under a participant-directed Plan) is prudent for ERISA purposes, a Plan fiduciary should consider all relevant facts and circumstances including, without limitation, possible limitations on the redemption of the Notes, whether the investment provides sufficient liquidity in light of the foreseeable needs of the Plan (or the participant account in a participant-directed Plan) It should be noted that it is the obligation of the appropriate fiduciary for each Plan to consider whether an investment in the Notes by the Plan (or making such Notes available for investment under a participant-directed Plan), when judged in light of the overall portfolio of the Plan, will meet the prudence, diversification and other applicable requirements of ERISA and the Code. A fiduciary of a Non-ERISA Arrangement should consider whether an investment in the Notes satisfies its obligations under Similar Laws.

In addition to ERISA’s general fiduciary standards, Section 406 of ERISA and Section 4975 of the Code prohibit certain transactions involving the assets of a Plan and persons who have specified relationships to the Plan, i.e., “parties in interest” as defined in Section 3(14) of ERISA or “disqualified persons” as defined in Section 4975(e)(2) of the Code (we refer to the foregoing collectively as “parties in interest”) unless exemptive relief is available under applicable law or an exemption issued by the U.S. Department of Labor. Parties in interest that engage in a non-exempt prohibited transaction may be subject to excise taxes and other penalties and liabilities under ERISA and Section 4975 of the Code. In addition, the fiduciary of the Plan that violates these prohibited transaction rules may be subject to penalties and liabilities under ERISA and the Code.

TABLE OF CONTENTS

The plan asset regulations provide that the assets of an entity may be deemed assets of a Plan by reason of that Plan’s investment in equity interests of the entity (so-called “Plan look-through”) unless an exemption under the plan assets regulations applies. If our assets were deemed to be assets of a Plan that purchased Notes, among other things, the provisions of ERISA and Section 4975 of the Code that apply to the Plan would apply to transactions in which we engage. There will not be Plan look-through if the investment by Plans is in a form other than an equity interest. The term equity interest under the plan asset regulations means any interest in an entity other than an instrument that is treated as indebtedness under applicable local law and which has no substantial equity features. We believe that the Notes will be treated as indebtedness without substantial equity features for purposes of the plan asset regulations (although we make no assurances to that effect). This assessment is based upon the traditional debt features of the Notes (although by no means free from doubt). Accordingly, we believe that our assets should not be treated as plan assets under the plan asset regulations as result of investment in the Notes by Plans.

Nevertheless, without regard to whether the Notes may be treated as debt for ERISA purposes, we, the underwriter and our and the underwriter’s current and future affiliates may be parties in interest with respect to many Plans and the purchase, holding or disposition of the Notes by or on behalf of, or with the assets of, such Plans could be considered to give rise to a direct or indirect prohibited transaction under ERISA, Section 4975 of the Code, Similar Law or the applicable regulations thereunder. Neither we, nor any underwriter, nor any of our or their respective affiliates is making or will make an investment recommendation or is providing investment advice in connection with the decision to invest in the Notes, and none of us is acting or will act as a fiduciary (within the meaning of Section 3(21) of ERISA or Section 4975(e)(3) of the Code) to the Plan in connection with the Plan’s acquisition of any Notes or any interest in the Notes. Thus, a Plan fiduciary considering an investment in securities should also consider whether such an investment might constitute or give rise to a prohibited transaction under Section 406 of ERISA, Section 4975 of the Code, Similar Law or the applicable regulations thereunder. For example, the Notes may be deemed to represent a direct or indirect sale of property, extension of credit or furnishing of services between us and an investing Plan which would be prohibited if we are a party in interest with respect to the Plan unless exemptive relief were available under applicable law or an applicable exemption.

In this regard, each prospective purchaser that is, or is acting on behalf of or with the assets of, a Plan, and proposes to purchase Notes, should consider the exemptive relief available under the following prohibited transaction class exemptions, or PTCEs: (A) the in-house asset manager exemption (PTCE 96-23); (B) the insurance company general account exemption (PTCE 95-60); (C) the bank collective investment fund exemption (PTCE 91-38); (D) the insurance company pooled separate account exemption (PTCE 90-1); and (E) the qualified professional asset manager exemption (PTCE 84-14). In addition, ERISA Section 408(b)(17) and Section 4975(d)(20) of the Code may provide a limited exemption for the purchase and sale of Notes, provided that neither the issuer of the Notes nor any of its affiliates have or exercise any discretionary authority or control or render any investment advice with respect to the assets of the Plan involved in the transaction and provided further that the Plan pays no more, and receives no less, than adequate consideration in connection with the transaction (the so-called “service provider exemption”). There can be no assurances, however, that any of these statutory or class exemptions will be available with respect to transactions involving the Notes or with respect to any particular Plan. In this circumstance, the Plan and fiduciaries of the Plan proposing to invest in the Notes should consult with their counsel to determine whether an investment in the Notes would result in a transaction that is prohibited by ERISA, Section 4975 of the Code or, with respect to Non-ERISA Arrangements, Similar Laws.

Due to the foregoing, the Notes should not be purchased or held by any Plan, Non-ERISA Arrangement or person investing “plan assets” of any Plan, if the purchase and holding will constitute a nonexempt prohibited transaction under ERISA and the Code or similar violation of any applicable Similar Law. Accordingly, each purchaser or holder of a Note, and each fiduciary who causes any entity to purchase or hold a Note, shall be deemed to have represented and warranted, on each day such purchaser or holder purchases, holds or disposes of such Note or Notes, that either: (i) it is neither a Plan nor a Non-ERISA Arrangement and it is not purchasing, holding or disposing of the Note or Notes on behalf of or with the assets of any Plan or Non-ERISA Arrangement; or (ii) its purchase, holding and subsequent disposition of such Note or Notes shall not constitute or result in a non-exempt prohibited transaction under Section 406 of ERISA, Section 4975 of the Code or any provision of Similar Law; or a breach of fiduciary or other duty or applicable law.

TABLE OF CONTENTS

Each purchaser or holder of a Note will have exclusive responsibility for ensuring that its purchase, holding and subsequent disposition of the Note does not violate ERISA, the Code, any Similar Law or the applicable regulations thereunder. Nothing herein shall be construed as a representation that an investment in the Notes would meet any or all of the relevant legal requirements with respect to investments by, or that an investment in the Notes is appropriate for, Plans or Non-ERISA Arrangements generally or any particular Plan or Non-ERISA Arrangement.

THE FOREGOING SUMMARY REGARDING CERTAIN ASPECTS OF ERISA AND THE CODE IS BASED ON ERISA, THE CODE, JUDICIAL DECISIONS AND UNITED STATES DEPARTMENT OF LABOR AND IRS REGULATIONS AND RULINGS THAT ARE IN EXISTENCE ON THE DATE OF THIS PROSPECTUS SUPPLEMENT. THE FOREGOING DISCUSSION IS GENERAL IN NATURE AND IS NOT INTENDED TO BE ALL-INCLUSIVE AND SHOULD NOT BE CONSTRUED AS LEGAL ADVICE. DUE TO THE COMPLEXITY OF THESE RULES AND THE PENALTIES THAT MAY BE IMPOSED UPON PERSONS INVOLVED IN NON-EXEMPT PROHIBITED TRANSACTIONS OR OTHER VIOLATIONS OF THESE RULES, IT IS PARTICULARLY IMPORTANT THAT FIDUCIARIES, OR OTHER PERSONS CONSIDERING PURCHASING THE NOTES (AND HOLDING THE NOTES) ON BEHALF OF, OR WITH THE ASSETS OF, ANY PLAN OR NON-ERISA ARRANGEMENT, CONSULT WITH THEIR COUNSEL REGARDING THE POTENTIAL APPLICABILITY OF ERISA, SECTION 4975 OF THE CODE AND ANY SIMILAR LAWS TO SUCH INVESTMENT AND WHETHER AN EXEMPTION WOULD BE APPLICABLE TO THE PURCHASE AND HOLDING OF THE NOTES.

UNDERWRITING (CONFLICT OF INTEREST)

We and the underwriters named below, for whom Keefe, Bruyette & Woods, Inc. is acting as representative, have entered into an underwriting agreement dated as of the date of this prospectus supplement. Subject to certain conditions, the underwriters have severally agreed to purchase, and we have agreed to sell to them, severally, the respective principal amount of the Notes set forth opposite their names below:

Initial Purchasers	Principal Amount
Keefe, Bruyette & Woods, Inc.		$
Piper Sandler & Co.		$
Goldman Sachs & Co. LLC		$
Raymond James & Associates, Inc.		$
Total		$

The underwriting agreement provides that the obligations of the several underwriters to pay for and accept delivery of the Notes is subject to, among other things, the approval of certain legal matters by their counsel and certain other conditions. The underwriters are obligated to take and pay for all of the Notes if any are taken. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the nondefaulting underwriters may be increased or the underwriting agreement may be terminated.

We expect that delivery of the Notes will be made to investors on or about , 2021 which will be the business day following the date hereof (such settlement being referred to as “T+ ”). Under Rule 15c6-1 of the Exchange Act, trades in the secondary market generally are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes prior to the delivery of the Notes will be required, by virtue of the fact that the Notes will initially settle in T+ , to specify an alternate settlement arrangement at the time of any such trade to prevent a failed settlement. Purchasers of the Notes who wish to trade the Notes prior to their date of delivery hereunder should consult their advisors.

The underwriters initially propose to offer the Notes directly to the public at the public offering price that appears on the cover page of this prospectus supplement and to certain dealers at that price less a selling concession not in excess of $ per Note. Any underwriter may allow, and such dealers may reallow, a discount not in excess of $ per Note, to certain other brokers or dealers. After the initial offering of the Notes to the public, the underwriters may vary the offering price and other selling terms of the Notes from time to time. The offering of the Notes by the underwriters is subject to receipt and acceptance and subject to the underwriters’ right to reject any order in whole or in part.

The following table shows the per Note and total underwriting discounts we will pay the underwriters.

	Per Note					%
	Total				$

We estimate that our total expenses for this offering, excluding underwriting discounts, will be approximately $ million. We have also agreed to reimburse the underwriters’ up to $200,000 for their counsel fees and other expenses related to the offering. In accordance with Financial Industry Regulatory Authority (“FINRA”) Rule 5110, these reimbursed fees and expenses are deemed underwriting compensation for this offering.

No Sales of Similar Securities

We have agreed, for a period from the date of the underwriting agreement through and including the closing date of the offering, not to offer, sell, contract to sell, pledge or otherwise dispose of, directly or

S-43

TABLE OF CONTENTS

indirectly, any debt securities that are issued or guaranteed by us or any nonconvertible preferred stock issued by us or any of our subsidiaries without the prior written consent of the underwriters.

No Public Trading Market

There is currently no public trading market for the Notes. In addition, we have not applied and do not intend to apply to list the Notes on any securities exchange or to have the Notes quoted on a quotation system. The underwriters have advised us that they intend to make a market in the Notes. However, they are not obligated to do so and may discontinue any market-making in the Notes at any time in their sole discretion. Therefore, we cannot assure you that a liquid trading market for the Notes will develop, that you will be able to sell your Notes at a particular time, or that the price you receive when you sell will be favorable. If an active trading market for the Notes does not develop, the market price and liquidity of the Notes may be adversely affected. If the Notes are traded, they may trade at a discount from their initial offering price, depending on prevailing interest rates, the market for similar securities, the credit ratings for the Notes, our operating performance and financial condition, general economic conditions and other factors.

Price Stabilization, Short Positions

In connection with this offering of the Notes, the underwriters may engage in overallotment and stabilizing transactions in accordance with Regulation M under the Exchange Act. Overallotment involves sales in excess of the offering size, which create a short position for the underwriters. Stabilizing transactions involve bids to purchase the Notes in the open market for the purpose of pegging, fixing, or maintaining the price of the Notes. Stabilizing transactions may cause the price of the Notes to be higher than it would otherwise be in the absence of those transactions. If the underwriters engage in stabilizing transactions, they may discontinue them at any time.

Neither we nor the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the Notes. In addition, neither we nor the underwriters make any representation that the underwriters will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

Other Relationships

The underwriters and their respective affiliates are full service financial institutions. Certain of the underwriters and their respective affiliates have, from time to time, performed, and may in the future perform, various financial advisory and investment banking services for the Company, for which they have received and may receive customary fees and expenses. Ronald L. Tillett, the Chairman of our Board of Directors, is an employee of Raymond James & Associates, Inc., an underwriter in this offering.

In addition, in the ordinary course of their various business activities, the underwriters and their respective affiliates have made or held, and may in the future make or hold, a broad array of investments, including serving as counterparties to certain derivative and hedging arrangements, and may have actively traded, and, in the future may actively trade, debt and equity securities (or related derivative securities), and financial instruments (including bank loans) for their own account and for the accounts of their customers and may have in the past and at any time in the future hold long and short positions in such securities and instruments. Such investment and securities activities may have involved, and in the future may involve, securities and instruments of the Company. If any of the underwriters or their affiliates have a lending relationship with us, certain of those underwriters or their affiliates routinely hedge, and certain other of those underwriters or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, these underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the Notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the Notes offered hereby. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

EXPERTS

The consolidated financial statements of Atlantic Union Bankshares Corporation appearing in its Annual Report on Form 10-K for the year ended December 31, 2020, and the effectiveness of Atlantic Union Bankshares Corporation’s internal control over financial reporting as of December 31, 2020 have been audited by Ernst & Young LLP, independent registered public accounting firm, as set forth in their reports thereon, included therein, and incorporated herein by reference. Such consolidated financial statements are incorporated herein by reference in reliance upon such reports given on the authority of such firm as experts in accounting and auditing.

With respect to the unaudited condensed consolidated interim financial information of Atlantic Union Bankshares Corporation for the three-month periods ended March 31, 2021 and 2020, the three and six-month periods ended June 30, 2021 and 2020, and the three and nine-month periods ended September 30, 2021 and 2020 incorporated by reference herein, Ernst & Young LLP reported that they have applied limited procedures in accordance with professional standards for a review of such information. However, their separate reports dated May 6, 2021, August 5, 2021 and November 4, 2021, included in Atlantic Union Bankshares Corporation’s Quarterly Reports on Form 10-Q for the quarters ended March 31, 2021, June 30, 2021, and September, 30, 2021, and incorporated by reference herein, states that they did not audit and they do not express an opinion on that interim financial information. Accordingly, the degree of reliance on their report on such information should be restricted in light of the limited nature of the review procedures applied. Ernst & Young LLP is not subject to the liability provisions of Section 11 of the Securities Act of 1933 (the “Act”) for their reports on the unaudited interim financial information because those reports are not a “report” or a “part” of the Registration Statement prepared or certified by Ernst & Young LLP within the meaning of Sections 7 and 11 of the Act.

TABLE OF CONTENTS

DESCRIPTION OF COMMON STOCK

The following summary description of the material features of the common stock of Atlantic Union is qualified in its entirety by reference to the applicable provisions of Virginia law and by Atlantic Union’s Articles of Incorporation, as amended and restated (the “Articles”), and Atlantic Union’s Bylaws, as amended and restated (the “Bylaws”).

General

Each share of our common stock has the same relative rights as, and is identical in all respects to, each other share of our common stock. Our common stock is traded on the NASDAQ Global Select Market under the symbol “AUB.” All of the outstanding shares of common stock are, and any common stock issued and sold under this prospectus will be, fully paid and nonassessable.

The transfer agent for our common stock is Computershare, 250 Royall Street, Canton, Massachusetts 02021.

Dividends

Our shareholders are entitled to receive dividends or distributions that our Board of Directors (also referred to as the “Board”) may declare out of funds legally available for those payments. The payment of distributions by Atlantic Union is subject to the restrictions of Virginia law applicable to the declaration of distributions by a corporation. A Virginia corporation generally may not authorize and make distributions if, after giving effect to the distribution, it would be unable to meet its debts as they become due in the usual course of business or if the corporation’s total assets would be less than the sum of its total liabilities plus the amount that would be needed, if it were dissolved at that time, to satisfy the preferential rights of shareholders whose rights are superior to the rights of those receiving the distribution. In addition, the payment of distributions to shareholders is subject to any prior rights of holders of outstanding preferred stock.

As a bank holding company, our ability to pay dividends is affected by the ability of Atlantic Union Bank, our bank subsidiary, to pay dividends to us. The ability of our bank subsidiary, as well as Atlantic Union, to pay dividends in the future is, and could be further, influenced by bank regulatory requirements and capital guidelines.

Liquidation Rights

In the event of any liquidation, dissolution or winding up of Atlantic Union, the holders of shares of our common stock will be entitled to receive, after payment of all debts and liabilities of Atlantic Union and after satisfaction of all liquidation preferences applicable to any preferred stock, all remaining assets of Atlantic Union available for distribution in cash or in kind.

Voting Rights

The holders of our common stock are entitled to one vote per share, and in general, a majority of votes cast with respect to a matter is sufficient to authorize action upon routine matters. Directors are elected by a majority of the votes cast in uncontested director elections. Atlantic Union maintains a “plurality vote” standard in contested director elections (i.e., where the number of nominees exceeds the number of directors to be elected). The holders of our common stock are not entitled to cumulative voting rights in the election of directors.

Directors and Classes of Directors

Until our 2021 annual meeting of shareholders, our Board of Directors will be divided into three classes, apportioned as evenly as possible, with directors serving staggered three-year terms. Notwithstanding the foregoing and without shortening the term of any director previously elected, (i) at our 2021 annual meeting

TABLE OF CONTENTS

of shareholders, director nominees whose terms expire at that meeting will be elected to hold office until our 2022 annual meeting of shareholders, (ii) at our 2022 annual meeting of shareholders, director nominees whose terms expire at that meeting will be elected to hold office until our 2023 annual meeting of shareholders and (iii) at our 2023 annual meeting of shareholders and each annual meeting of shareholders thereafter, all director nominees will be elected to hold office until our next annual meeting of shareholders and until a successor is elected and qualified or until the director’s prior death, resignation or removal. Currently, our Board of Directors consists of 17 directors. Under the Articles, directors may be removed only for cause upon the affirmative vote of at least two-thirds of the outstanding shares entitled to vote.

No Preemptive Rights; Redemption and Assessment

Holders of shares of our common stock will not be entitled to preemptive rights with respect to any shares that may be issued. Our common stock is not subject to redemption or any sinking fund and the outstanding shares are fully paid and nonassessable.

Securities Are Not Insured by the FDIC

Investments in our common stock or any of our equity or debt securities will not qualify as deposits or savings accounts and will not be insured or guaranteed by the FDIC or any other governmental agency and are subject to investment risk, including the possible loss of principal.

Certain Anti-Takeover Provisions of Our Articles and Bylaws and Virginia Law

General. Our Articles and Bylaws and the Virginia Stock Corporation Act (the “Virginia SCA”) contain certain provisions designed to enhance the ability of our Board of Directors to deal with attempts to acquire control of the Company. These provisions, and the ability to set the voting rights, preferences and other terms of any series of preferred stock that may be issued, may be deemed to have an anti-takeover effect and may discourage takeovers (which certain shareholders may deem to be in their best interest). To the extent that such takeover attempts are discouraged, temporary fluctuations in the market price of our common stock resulting from actual or rumored takeover attempts may be inhibited. These provisions also could discourage or make more difficult a merger, tender offer or proxy contest, even though such transaction may be favorable to the interests of shareholders, and could potentially adversely affect the market price of our common stock.

The following briefly summarizes protective provisions that are contained in our Articles and Bylaws and provided by the Virginia SCA. This summary is necessarily general and is not intended to be a complete description of all the features and consequences of those provisions, and is qualified in its entirety by reference to our Articles and Bylaws and the statutory provisions contained in the Virginia SCA.

Supermajority Provision. The Virginia SCA provides that, unless a corporation’s articles of incorporation provide for a greater or lesser vote, certain significant corporate actions must be approved by the affirmative vote of more than two-thirds of the votes entitled to be cast on the matter. Certain corporate actions requiring a more than two-thirds vote include:

•

adoption of plans of merger or share exchange;

•

sales of all or substantially all of a corporation’s assets other than in the ordinary course of business; and

•

adoption of plans of dissolution.

The Virginia SCA provides that a corporation’s articles may either increase the vote required to approve those actions or may decrease the vote required to not less than a majority of all the votes cast by each voting group entitled to vote at a meeting at which a quorum of the voting group exists.

Our Articles state that the actions set out above must be approved by a majority of all votes entitled to be cast on the transaction by each voting group entitled to vote at a meeting at which a quorum of the voting group is present, provided that the transaction has been approved and recommended by at least two-thirds of

TABLE OF CONTENTS

the directors in office at the time of such approval and recommendation. If the transaction is not so approved and recommended, then the transaction must be approved by the vote of 80% or more of all votes entitled to be cast on such transactions by each voting group entitled to vote on the transaction.

The provisions of our Articles and the Virginia SCA could tend to make the acquisition of Atlantic Union more difficult to accomplish without the cooperation or favorable recommendation of our Board of Directors.

Staggered Board Terms. Our Articles provide that, until our 2021 annual meeting of shareholders, our Board of Directors will be divided into three classes, apportioned as evenly as possible, with directors serving staggered three-year terms. Notwithstanding the foregoing and without shortening the term of any director previously elected, (i) at our 2021 annual meeting of shareholders, director nominees whose terms expire at that meeting will be elected to hold office until our 2022 annual meeting of shareholders, (ii) at our 2022 annual meeting of shareholders, director nominees whose terms expire at that meeting will be elected to hold office until our 2023 annual meeting of shareholders and (iii) at our 2023 annual meeting of shareholders and each annual meeting of shareholders thereafter, all director nominees will be elected to hold office until our next annual meeting of shareholders and until a successor is elected and qualified or until the director’s prior death, resignation or removal. Currently, our Board of Directors consists of 17 directors. Under the Articles, directors may be removed only for cause upon the affirmative vote of at least two-thirds of the outstanding shares entitled to vote.

State Anti-Takeover Statutes. Virginia has two anti-takeover statutes in force, the Affiliated Transactions Statute and the Control Share Acquisitions Statute.

The Affiliated Transaction Statute of the Virginia SCA contains provisions governing “affiliated transactions.” These include various transactions such as mergers, share exchanges, sales, leases, or other dispositions of material assets, issuances of securities, dissolutions, and similar transactions with an “interested shareholder.” An interested shareholder is generally the beneficial owner of more than 10% of any class of a corporation’s outstanding voting shares. During the three years following the date a shareholder becomes an interested shareholder, any affiliated transaction with the interested shareholder must be approved by both a majority (but not less than two) of the “disinterested directors” (those directors who were directors before the interested shareholder became an interested shareholder or who were recommended for election by a majority of the disinterested directors) and by the affirmative vote of the holders of two-thirds of the corporation’s voting shares other than shares beneficially owned by the interested shareholder. These requirements do not apply to affiliated transactions if, among other things, a majority of the disinterested directors approve the interested shareholder’s acquisition of voting shares making such a person an interested shareholder before such acquisition. Beginning three years after the shareholder becomes an interested shareholder, the corporation may engage in an affiliated transaction with the interested shareholder if:

•

the transaction is approved by the holders of two-thirds of the corporation’s voting shares, other than shares beneficially owned by the interested shareholder;

•

the affiliated transaction has been approved by a majority of the disinterested directors; or

•

subject to certain additional requirements, in the affiliated transaction the holders of each class or series of voting shares will receive consideration meeting specified fair price and other requirements designed to ensure that all shareholders receive fair and equivalent consideration, regardless of when they tendered their shares.

Under the Virginia SCA’s Control Share Acquisitions Statute, voting rights of shares of stock of a Virginia corporation acquired by an acquiring person or other entity at ownership levels of 20%, 331∕3%, and 50% of the outstanding shares may, under certain circumstances, be denied. The voting rights may be denied:

•

unless conferred by a special shareholder vote of a majority of the outstanding shares entitled to vote for directors, other than shares held by the acquiring person and officers and directors of the corporation; or

TABLE OF CONTENTS

•

among other exceptions, such acquisition of shares is made pursuant to a merger agreement with the corporation or the corporation’s articles of incorporation or bylaws permit the acquisition of such shares before the acquiring person’s acquisition thereof.

If authorized in the corporation’s articles of incorporation or bylaws, the statute also permits the corporation to redeem the acquired shares at the average per share price paid for such shares if the voting rights are not approved or if the acquiring person does not file a “control share acquisition statement” with the corporation within 60 days of the last acquisition of such shares. If voting rights are approved for control shares comprising more than 50% of the corporation’s outstanding stock, objecting shareholders may have the right to have their shares repurchased by the corporation for “fair value.”

Corporations may provide in their articles of incorporation or bylaws to opt-out of the Affiliated Transactions Statute or the Control Share Acquisitions Statute. Atlantic Union has not opted-out of the Affiliated Transactions Statute or the Control Share Acquisitions Statute, and Atlantic Union’s Bylaws provide that it may, but is not required to, redeem shares of its common stock which have been the subject of a “control share acquisition” as defined in the Control Share Acquisitions Statute.

Authorized Preferred Stock. Our Articles authorize the issuance of preferred stock and our Board of Directors may, subject to application of Virginia law and federal banking regulations, authorize the issuance of preferred stock at such times, for such purposes and for such consideration as our Board may deem advisable without further shareholder approval. The issuance of preferred stock under certain circumstances may have the effect of discouraging an attempt by a third party to acquire control of Atlantic Union by, for example, authorizing the issuance of a series of preferred stock with rights and preferences designed to impede the proposed transaction.

Liability and Indemnification of Officers and Directors. The Virginia SCA provides that in any proceeding brought by or in the right of a corporation or brought by or on behalf of shareholders of the corporation, the damages assessed against an officer or director arising out of a single transaction, occurrence or course of conduct may not exceed the lesser of (a) the monetary amount, including the elimination of liability, specified in the articles of incorporation or, if approved by the shareholders, in the bylaws as a limitation on or elimination of the liability of the officer or director, or (b) the greater of (i) $100,000 or (ii) the amount of cash compensation received by the officer or director from the corporation during the twelve months immediately preceding the act or omission for which liability was imposed. The liability of an officer or director is not limited under the Virginia SCA or a corporation’s articles of incorporation and bylaws if the officer or director engaged in willful misconduct or a knowing violation of the criminal law or of any federal or state securities law.

Our Articles provide that, to the full extent that the Virginia SCA permits the limitation or elimination of liability of directors or officers, a director or officer of Atlantic Union is not liable to Atlantic Union or its shareholders for monetary damages.

A Virginia corporation generally is authorized to indemnify its directors and officers in civil and criminal actions if they acted in good faith and believed their conduct to be in the best interests of the corporation and, in the case of criminal actions, had no reasonable cause to believe that the conduct was unlawful. The Virginia SCA requires such indemnification when a director or, unless limited by a corporation’s articles of incorporation, officer entirely prevails in the defense of any proceeding to which he or she was a party because he or she is or was a director or officer of the corporation, and further provides that a corporation may make any other or further indemnity (including indemnity to a proceeding by or in the right of the corporation), and may make additional provision for advances and reimbursement of expenses, if authorized by its articles of incorporation or shareholder-adopted bylaw or resolution, except an indemnity against willful misconduct or a knowing violation of the criminal law. The Virginia SCA establishes a statutory limit on liability of officers and directors of a corporation for damages assessed against them in a suit brought by or in the right of the corporation or brought by or on behalf of shareholders of the corporation and authorizes a corporation to specify a lower monetary limit on liability (including the elimination of liability for monetary damages) in the corporation’s articles of incorporation or bylaws; however, the liability of an officer or director will not be

TABLE OF CONTENTS

limited if such officer or director engaged in willful misconduct or a knowing violation of the criminal law or of any federal or state securities law.

Our Articles provide that, to the full extent permitted by the Virginia SCA, we are required to indemnify (i) any person who was or is a party to any proceeding, including a proceeding brought by a shareholder in the right of the company or brought by or on behalf of shareholders of the company, by reason of the fact that he or she is or was a director or officer of the company, or (ii) any director or officer who is or was serving at the request of the company as a director, trustee, partner or officer of another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise, against any liability incurred by him or her in connection with such proceeding unless he or she engaged in willful misconduct or a knowing violation of criminal law.

Dissenters’ and Appraisal Rights. The Virginia SCA provides that appraisal or dissenters’ rights are not available to holders of shares of any class or series of shares of a Virginia corporation in a merger when the stock is either listed on a national securities exchange, such as the NASDAQ Global Select Market, or is held by at least 2,000 shareholders of record and has a public float of at least $20 million. Despite this exception, appraisal or dissenters’ rights will be available to holders of common stock of a Virginia corporation in a merger if:

•

the articles of incorporation provide for appraisal or dissenters’ rights regardless of an available exception (our Articles do not authorize such special appraisal or dissenters’ rights);

•

in the case of a merger or share exchange, shareholders are required by the terms of the merger to accept anything for their shares other than cash, shares of the surviving or acquiring corporation, or shares of another corporation that are either listed on a national securities exchange or held by more than 2,000 shareholders of record having a public float of at least $20 million, or a combination of cash or such shares; or

•

the merger is an “affiliated transaction,” as described under “— State Anti-Takeover Statutes” above, and it has not been approved by a majority of the disinterested directors.

Our common stock is listed on the NASDAQ Global Select Market. Therefore, unless one of the exceptions outlined above applies to a given transaction, holders of our common stock are not entitled to appraisal or dissenters’ rights.

Amendments to our Articles of Incorporation and Bylaws. The Virginia SCA generally requires that in order for an amendment to the articles of incorporation to be adopted it must be approved by each voting group entitled to vote on the proposed amendment by more than two-thirds of all the votes entitled to be cast by that voting group, unless the Virginia SCA otherwise requires a greater vote, or the articles of incorporation provide for a greater or lesser vote, or a vote by separate voting groups. However, under the Virginia SCA, no amendment to the articles of incorporation may be approved by a vote that is less than a majority of all the votes cast on the amendment by each voting group entitled to vote at a meeting at which a quorum of the voting group exists.

Under the Virginia SCA, unless another process is set forth in the articles of incorporation or bylaws, a majority of the directors (except to the extent authority to amend the bylaws is reserved by the Virginia SCA), or, if a quorum exists at a meeting of shareholders, a majority of the shareholders present and entitled to vote may adopt, amend or repeal the bylaws.

Our Articles state that an amendment to the articles of incorporation must be approved by a majority of all the votes entitled to be cast on the amendment by each voting group entitled to vote at a meeting at which a quorum of the voting group is present, provided that the amendment has been approved and recommended by at least two-thirds of the directors in office at the time of such approval and recommendation. If the amendment is not so approved and recommended by two-thirds of the directors in office, then the amendment must be approved by the affirmative vote of 80% or more of all of the votes entitled to be cast on such amendment by each voting group entitled to vote.

TABLE OF CONTENTS

Our Bylaws may be amended, altered, or repealed by our Board of Directors at any time. Our shareholders have the power to rescind, alter, amend, or repeal any bylaws and to enact bylaws which, if so expressed by the shareholders, may not be rescinded, altered, amended, or repealed by our Board of Directors.

Increasing the Number of Directors. Under Virginia law, a board of directors may amend or repeal bylaws unless its company’s articles of incorporation or other provisions of Virginia law reserve such power exclusively in the shareholders or the shareholders, in adopting or amending particular bylaws, expressly prohibit the board of directors from amending or repealing that bylaw. Our Articles do not reserve the power to amend the Bylaws to increase or decrease the number of directors exclusively to the shareholders and no bylaw, and no amendment thereto, expressly prohibits our Board of Directors from amending the Bylaws to increase or decrease the number of directors. Any newly created directorships resulting from an increase in the number of authorized directors shall be filled by the affirmative vote of a majority of the directors then in office. As a result, if faced with an attempt to take control of our Board of Directors, our Board may increase the size of the Board and install directors opposed to the hostile takeover attempt.

Inability of Shareholders to Call Special Meetings. Pursuant to our Bylaws, special meetings of shareholders may be called only by the Chairman or Vice Chairman of the Board, if any, the Chief Executive Officer, the President, our Board of Directors or our Board’s Executive Committee. As a result, shareholders are not able to act on matters other than at annual shareholders meetings unless they are able to persuade the Chief Executive Officer, President, the Chairman or the Vice Chairman of the Board of Directors to call a special meeting.

Advance Notification Requirements. Our Bylaws require a shareholder who desires to nominate a candidate for election to our Board of Directors or to raise new business at an annual shareholders meeting to provide us advance notice not later than the close of business on the ninetieth day, nor earlier than the close of business on the one-hundred twentieth day, prior to the first anniversary of the commencement of the preceding year’s annual meeting of shareholders, provided, however, that in the event that the date of the annual meeting is more than thirty days before or more than seventy days after such anniversary date, notice by such shareholder must be so delivered not earlier than the close of business on the one-hundred twentieth day prior to such annual meeting and not later than the close of business on the later of the ninetieth day prior to such annual meeting or the tenth day following the day on which public announcement of the date of such meeting is first made by Atlantic Union. In no event shall the public announcement of an adjournment or postponement of an annual meeting of shareholders commence a new time period (or extend any time period) for the giving of a shareholder’s notice as described above. Our Bylaws further condition the presentation of shareholder nominations for director or proposals for business on compliance with a number of conditions. In addition, a shareholder must also comply with applicable rules of the SEC in order for his or her shareholder proposal to be included in our proxy statement relating to the annual meeting.

TABLE OF CONTENTS

DESCRIPTION OF PREFERRED STOCK

Our Board of Directors, without shareholder approval, is authorized under our Articles to issue, in one or more series, shares of preferred stock at such times, for such purposes and for such consideration as it may deem advisable. Our Board of Directors is also authorized to fix the designation, voting, conversion, preference and other relative rights, qualifications and limitations of any series of preferred stock.

As of the date of this prospectus, 500,000 shares of our preferred stock, par value $10.00, are authorized. We have 17,250 shares of Series A Preferred Stock outstanding.

The following summary description of the material features of the preferred stock of Atlantic Union that we may offer from time to time is qualified in its entirety by reference to the applicable provisions of Virginia law, our current Articles and the articles of amendment to our Articles relating to the particular series of preferred stock, a copy of which we will file with the SEC in connection with the sale of any series of preferred stock.

General

Our Board of Directors may authorize the issuance of one or more series of preferred stock and may establish and designate series and the number of shares and the relative rights, preferences and limitations of the respective series of the preferred stock offered by this prospectus and the applicable prospectus supplement. The shares of preferred stock, when issued and sold, will be fully paid and nonassessable.

The number of shares and all of the relative rights, preferences and limitations of the respective future series of preferred stock authorized by our Board of Directors will be described in the applicable prospectus supplement. The terms of a particular series of preferred stock may differ, among other things, in:

•

designation;

•

number of shares that constitute the series;

•

dividends (which may be cumulative or noncumulative), the dividend rate, or the method of calculating the dividend rate;

•

dividend periods, or the method of calculating the dividend periods;

•

redemption provisions, including whether, on what terms and at what prices the shares will be subject to redemption at our option and whether a sinking fund will be established;

•

voting rights;

•

preferences and rights upon liquidation or winding up;

•

whether and on what terms the shares will be convertible into or exchangeable for shares of any other class, series or security of ours or any other corporation or any other property (including whether the conversion or exchange is mandatory, at the option of the holder or our option, the period during which conversion or exchange may occur, the initial conversion or exchange price or rate and the circumstances or manner in which the amount of common or preferred stock or other securities issuable upon conversion or exchange may be adjusted);

•

for preferred stock convertible into our common stock, the number of shares of common stock to be reserved in connection with, and issued upon conversion of, the preferred stock (including whether the conversion or exchange is mandatory, the initial conversion or exchange price or rate and the circumstances or manner in which the amount of common stock issuable upon conversion or exchange may be adjusted) at the option of the holder or our option and the period during which conversion or exchange may occur; and

•

the other rights and privileges and any qualifications, limitations or restrictions of those rights or privileges.

TABLE OF CONTENTS

Each series of preferred stock will rank, with respect to the payment of dividends and the distribution of assets upon liquidation, dissolution or winding up:

•

junior to any series of our capital stock expressly stated to be senior to that series of preferred stock; and

•

senior to our common stock and any class of our capital stock expressly stated to be junior to that series of preferred stock.

Dividends

Dividends will be payable as they are declared by our Board of Directors at such time or times as it elects, and no holder of preferred stock will have any right to receive any dividend unless and until that dividend has been declared by our Board of Directors. The stated annual dividend may be declared and paid in increments during each calendar year. In connection with each dividend payment, our Board of Directors may set a record date in advance of the payment date for the purpose of determining the holders of shares preferred stock who are entitled to receive that dividend.

If described in the applicable prospectus supplement, we may pay cumulative cash dividends to the holders of preferred stock, when and as declared by our Board of Directors or a committee thereof, out of funds legally available for payment. The prospectus supplement will detail, as applicable, the annual rate of dividends or the method or formula for determining or calculating them, and the payment dates and payment periods for dividends. In the event that dividends are declared on the preferred stock, our Board of Directors or the committee will fix a record date for any such payment of dividends, which will be paid on the preferred stock to the holders of record on that record date.

We will not declare, pay or set aside for payment any dividends on any preferred stock ranking on a parity as to payment of dividends with the preferred stock unless we declare, pay or set aside for payment dividends on all the outstanding shares of preferred stock for all dividend payment periods ending on or before the dividend payment date for that parity stock.

Unless we have paid in full all unpaid cumulative dividends, if any, on the outstanding shares of preferred stock, we may not take any of the following actions with respect to our common stock or any other preferred stock of Atlantic Union ranking junior or on parity with the preferred stock as to dividend payments (unless otherwise described in the prospectus supplement):

•

declare, pay or set aside for payment any dividends, other than dividends payable in our common stock;

•

make other distributions;

•

redeem, purchase or otherwise acquire our common stock or junior preferred stock for any consideration; or

•

make any payment to or available for a sinking fund for the redemption of our common stock or junior preferred stock.

Conversion and Exchange

The prospectus supplement will indicate whether and on what terms the shares of any future series of preferred stock will be convertible into or exchangeable for shares of any other class, series or security of Atlantic Union or any other corporation or any other property (including whether the conversion or exchange is mandatory, at the option of the holder or our option, the period during which conversion or exchange may occur, the initial conversion or exchange price or rate and the circumstances or manner in which the amount of common or preferred stock or other securities issuable upon conversion or exchange may be adjusted). It will also indicate for preferred stock convertible into common stock, the number of shares of common stock to be reserved in connection with, and issued upon conversion of, the preferred stock (including whether the conversion or exchange is mandatory, the initial conversion or exchange price or rate and the circumstances or

TABLE OF CONTENTS

manner in which the amount of common stock issuable upon conversion or exchange may be adjusted) at the option of the holder or our option and the period during which conversion or exchange may occur.

Redemption

The prospectus supplement will indicate whether, and on what terms, the shares of any future series of preferred stock will be subject to redemption, mandatory or otherwise, or a sinking fund provision. The prospectus supplement will also indicate whether, and on what terms, including the redemption price and date on or after which redemption may occur, we may redeem shares of a series of the preferred stock.

Liquidation Rights

In the event of any liquidation, dissolution or winding up of Atlantic Union, the holders of shares of preferred stock outstanding will be entitled to receive, out of the assets of Atlantic Union available for distribution to shareholders, liquidating distributions in an amount equal to the stated value per share of preferred stock, as described in the Articles (as amended to establish the preferred stock) and/or the applicable prospectus supplement, plus accrued and accumulated but unpaid dividends, if any, to the date of final distribution, before any distribution is made to holders of:

•

any class or series of capital stock ranking junior to the preferred stock as to rights upon liquidation, dissolution or winding up; or

•

our common stock.

However, holders of the shares of preferred stock will not be entitled to receive the liquidation price of their shares until we have paid or set aside an amount sufficient to pay in full the liquidation preference of any class or series of our capital stock ranking senior as to rights upon liquidation, dissolution or winding up. Unless otherwise provided in the applicable prospectus supplement, neither a consolidation or merger of Atlantic Union with or into another corporation nor a merger of another corporation with or into Atlantic Union nor a sale or transfer of all or part of Atlantic Union’s assets for cash or securities will be considered a liquidation, dissolution or winding up of Atlantic Union.

If, upon any liquidation, dissolution or winding up of Atlantic Union, assets of Atlantic Union then distributable are insufficient to pay in full the amounts payable with respect to the preferred stock and any other preferred stock ranking on parity with the preferred stock as to rights upon liquidation, dissolution or winding up, the holders of shares of the preferred stock and of shares of that other preferred stock will participate ratably in any distribution in proportion to the full respective preferential amounts to which they are entitled. After we have paid the full amount of the liquidating distribution to which they are entitled, the holders of the preferred stock will not be entitled to any further participation in any distribution of assets by Atlantic Union.

Voting Rights

Unless otherwise determined by our Board of Directors and indicated in the prospectus supplement, holders of the preferred stock will not have any voting rights except as from time to time required by law.

Series A Preferred Stock

The following is a description of the particular terms of the Series A Preferred Stock. The following description is qualified in its entirety by the Articles of Amendment relating to the Series A Preferred Stock (the “Articles of Amendment”), and where this description is inconsistent with the description of the Series A Preferred Stock contained in the Articles of Amendment, the Articles of Amendment will control.

General

The Series A Preferred Stock is a single series of our authorized preferred stock. Shares of the Series A Preferred Stock are fully paid and nonassessable. The depositary is the sole holder of shares of the Series A

TABLE OF CONTENTS

Preferred Stock. The holders of Depositary Shares are required to exercise their proportional rights in the Series A Preferred Stock through the depositary, as described in the section entitled “Description of Depositary Shares.”

Shares of the Series A Preferred Stock rank senior to our common stock and at least equally with each other series of preferred stock we have or may issue if provided for in the articles of amendment relating to such preferred stock or otherwise (except for any senior stock that may be issued with the requisite consent of the holders of the Series A Preferred Stock and all other parity stock, if any), with respect to the payment of dividends and distributions of assets upon liquidation, dissolution or winding up of Atlantic Union. In addition, we will generally be able to pay dividends and distributions upon liquidation, dissolution or winding up only out of lawfully available assets for such payment (after satisfaction of all claims for indebtedness and other non-equity claims). Further, the Series A Preferred Stock may be fully subordinated to interests held by the U.S. government in the event that we enter into a receivership, insolvency, liquidation, or similar proceeding, including a proceeding under the Orderly Liquidation Authority of the Dodd-Frank Act.

The Series A Preferred Stock is not convertible into, or exchangeable for, shares of any other class or series of stock or other securities of Atlantic Union. The Series A Preferred Stock has no stated maturity and will not be subject to any sinking fund or other obligation of Atlantic Union to redeem or repurchase the Series A Preferred Stock.

We reserve the right to re-open the Series A Preferred Stock and issue additional shares of Series A Preferred Stock either through public or private sales at any time and from time to time that may or may not involve additional depositary shares. The additional shares would form a single series with the Series A Preferred Stock already outstanding. In addition, we may from time to time, without notice to or consent of holders of the Series A Preferred Stock or the Depositary Shares, issue additional shares of preferred stock that rank equally with or junior to the Series A Preferred Stock.

Dividends

General

Dividends on the Series A Preferred Stock are not cumulative. If our Board of Directors or a duly authorized committee of our Board of Directors does not declare a dividend on the Series A Preferred Stock in respect of a dividend period, then no dividend shall be deemed to have accrued for such dividend period, be payable on the applicable dividend payment date, or be cumulative, and we will have no obligation to pay any dividend for that dividend period, whether or not our Board of Directors or a duly authorized committee of our Board of Directors declares a dividend on the Series A Preferred Stock for any subsequent dividend period. A dividend period is the period from and including a dividend payment date to but excluding the next dividend payment date.

Holders of Series A Preferred Stock are entitled to receive, when, as, and if declared by our Board of Directors or a duly authorized committee of our Board of Directors, out of assets legally available for the payment of dividends under Virginia law, non-cumulative cash dividends based on the liquidation preference of the Series A Preferred Stock at a rate equal to 6.875% per annum for each quarterly dividend period from the original issue date of the Depositary Shares through the redemption date of the Series A Preferred Stock, if any. In the event that we issue additional shares of Series A Preferred Stock after the original issue date, dividends on such shares will accrue from the original issue date of such additional shares.

If declared by our Board of Directors or a duly authorized committee of our Board of Directors, we will pay dividends on the outstanding Series A Preferred Stock quarterly in arrears, on March 1, June 1, September 1 and December 1 of each year, beginning on September 1, 2020 (each such date, a “dividend payment date”). If any date on which dividends would otherwise be payable is not a business day, then the dividend payment date will be the next business day without any adjustment to the amount of dividends paid. A business day means any weekday that is not a legal holiday in New York, New York, and is not a day on which banking institutions in New York, New York, are closed.

TABLE OF CONTENTS

Dividends are payable to holders of record of Series A Preferred Stock as they appear on our stock register on the applicable record date, which shall be the 15th calendar day before the applicable dividend payment date, or such other record date, not exceeding 30 days before the applicable payment date, as shall be fixed by our Board of Directors or a duly authorized committee of our Board of Directors. The corresponding record dates for the Depositary Shares will be the same as the record dates for the Series A Preferred Stock.

A dividend period is the period from and including a dividend payment date to but excluding the next dividend payment date, except that the initial dividend period will commence on and include the original issue date of the Series A Preferred Stock. Dividends payable on the Series A Preferred Stock will be computed on the basis of a 360-day year consisting of twelve 30-day months.

Additional Information

Our ability to pay dividends on the Series A Preferred Stock depends on the ability of our subsidiaries, including Atlantic Union Bank, to pay dividends to us. Our ability and the ability of our subsidiaries to pay dividends in the future is subject to bank regulatory requirements and capital guidelines and policies established by the Virginia Bureau of Financial Institutions and the Federal Reserve.

So long as any share of Series A Preferred Stock remains outstanding, (1) no dividend shall be declared or paid or set aside for payment and no distribution shall be declared or made or set aside for payment on any junior stock (other than (i) a dividend payable solely in junior stock or (ii) any dividend in connection with the implementation of a shareholders’ rights plan, or the redemption or repurchase of any rights under any such plan), (2) no shares of junior stock shall be repurchased, redeemed or otherwise acquired for consideration by us, directly or indirectly (other than (i) as a result of a reclassification of junior stock for or into other junior stock, (ii) the exchange or conversion of one share of junior stock for or into another share of junior stock, (iii) through the use of the proceeds of a substantially contemporaneous sale of other shares of junior stock, (iv) purchases, redemptions or other acquisitions of shares of junior stock in connection with any employment contract, benefit plan or other similar arrangement with or for the benefit of employees, officers, directors or consultants, (v) purchases of shares of junior stock pursuant to a contractually binding requirement to buy junior stock existing prior to the preceding dividend period, including under a contractually binding stock repurchase plan, (vi) the purchase of fractional interests in shares of junior stock pursuant to the conversion or exchange provisions of such stock or the security being converted or exchanged, (vii) purchases or other acquisitions by any of our broker-dealer subsidiaries solely for the purpose of market making, stabilization or customer facilitation transactions in junior stock in the ordinary course of business, (viii) purchases by any of our broker-dealer subsidiaries of our capital stock for resale pursuant to an offering by us of such capital stock underwritten by such broker-dealer subsidiary, or (ix) the acquisition by us or any of our subsidiaries of record ownership in junior stock for the beneficial ownership of any other persons (other than for the beneficial ownership by us or any of our subsidiaries), including as trustees or custodians), nor shall any monies be paid to or made available for a sinking fund for the redemption of any such securities by us and (3) no shares of parity stock, if any, shall be repurchased, redeemed or otherwise acquired for consideration by us, directly or indirectly, during a dividend period (other than (i) pursuant to pro rata offers to purchase all, or a pro rata portion, of the Series A Preferred Stock and such parity stock, if any, (ii) as a result of a reclassification of parity stock for or into other parity stock, (iii) the exchange or conversion of parity stock for or into other parity stock or junior stock, (iv) through the use of the proceeds of a substantially contemporaneous sale of other shares of parity stock, (v) purchases of shares of parity stock pursuant to a contractually binding requirement to buy parity stock existing prior to the preceding dividend period, including under a contractually binding stock repurchase plan, (vi) the purchase of fractional interests in shares of parity stock pursuant to the conversion or exchange provisions of such stock or the security being converted or exchanged, (vii) purchases or other acquisitions by any of our broker-dealer subsidiaries solely for the purpose of market making, stabilization or customer facilitation transactions in parity stock in the ordinary course of business, (viii) purchases by any of our broker-dealer subsidiaries of our capital stock for resale pursuant to an offering by us of such capital stock underwritten by such broker-dealer subsidiary, or (ix) the acquisition by us or any of our subsidiaries of record ownership in parity stock for the beneficial ownership of any other persons (other than for the beneficial ownership by us or any of our subsidiaries), including as trustees or custodians), nor shall any monies be paid to or made available for a sinking fund for the redemption of any such securities

TABLE OF CONTENTS

by us unless, in each case, the full dividends for the preceding dividend period on all outstanding shares of Series A Preferred Stock have been paid in full or declared and a sum sufficient for the payment thereof has been set aside for payment.

We will not declare or pay or set apart funds for the payment of dividends on any parity stock, unless we have paid or set apart funds for the payment of dividends on the Series A Preferred Stock. When dividends are not paid in full upon the shares of Series A Preferred Stock and parity stock, if any, all dividends declared upon shares of Series A Preferred Stock and parity stock, if any, will be declared on a proportional basis so that the amount of dividends declared per share will bear to each other the same ratio that accrued dividends for the then-current dividend period per share on the Series A Preferred Stock, and accrued dividends, including any accumulations, if any, on parity stock, if any, bear to each other.

As used in this prospectus, “junior stock” means our common stock and any other class or series of our stock hereafter authorized over which the Series A Preferred Stock has preference or priority in the payment of dividends or in the distribution of assets on any liquidation, dissolution or winding up of Atlantic Union. As of the date of this prospectus, our common stock is the only series of junior stock outstanding.

As used in this prospectus, “parity stock” means any other class or series of our stock that ranks on a parity with the Series A Preferred Stock with respect to the payment of dividends and distributions of assets upon liquidation, dissolution or winding up of Atlantic Union. As of the date of this prospectus, there are no series of parity stock outstanding.

As used in this prospectus, “senior stock” means any other class or series of our stock ranking senior to the Series A Preferred Stock with respect to the payment of dividends and distributions of assets upon liquidation, dissolution or winding up of Atlantic Union. As of the date of this prospectus, there are no series of senior stock outstanding.

Subject to the considerations described above, and not otherwise, dividends (payable in cash, stock or otherwise), as may be determined by our Board of Directors or a duly authorized committee of our Board of Directors, may be declared and paid on our common stock and any other stock ranking equally with or junior to the Series A Preferred Stock from time to time out of any assets legally available for such payment, and the holders of Series A Preferred Stock shall not be entitled to participate in any such dividend.

Dividends on the Series A Preferred Stock will not be declared, paid or set aside for payment to the extent such act would cause us to fail to comply with applicable laws and regulations, including applicable capital adequacy guidelines.

Redemption

Optional Redemption

The Series A Preferred Stock is not subject to any mandatory redemption, sinking fund or other similar provisions. We may redeem the Series A Preferred Stock at our option, in whole or in part, from time to time, on any dividend payment date on or after September 1, 2025, at a redemption price equal to $10,000 per share (equivalent to $25 per Depositary Share), plus any declared and unpaid dividends on the shares of Series A Preferred Stock called for redemption up to the redemption date. Neither the holders of Series A Preferred Stock nor holders of Depositary Shares have the right to require the redemption or repurchase of the Series A Preferred Stock.

Redemption Following a Regulatory Capital Treatment Event

We may redeem the Series A Preferred Stock in whole but not in part at any time within 90 days following a regulatory capital treatment event, in whole but not in part, at a redemption price equal to $10,000 per share (equivalent to $25 per Depositary Share), plus any declared and unpaid dividends on the shares of Series A Preferred Stock called for redemption up to the redemption date. A “regulatory capital treatment event” means the good faith determination us that, as a result of (i) any amendment to, or change (including any

TABLE OF CONTENTS

announced prospective change) in, the laws or regulations of the United States or any political subdivision of or in the United States that is enacted or becomes effective after the initial issuance of any share of Series A Preferred Stock; (ii) any proposed change in those laws or regulations that is announced or becomes effective after the initial issuance of any share of Series A Preferred Stock; or (iii) any official administrative decision or judicial decision or administrative action or other official pronouncement interpreting or applying those laws or regulations that is announced after the initial issuance of any share of Series A Preferred Stock, there is more than an insubstantial risk that we will not be entitled to treat the full liquidation value of the shares of Series A Preferred Stock then outstanding as “Tier 1 Capital” (or its equivalent) for purposes of the capital adequacy guidelines of Federal Reserve Regulation Y (or, as and if applicable, the capital adequacy guidelines or regulations of any successor appropriate federal banking regulator or agency), as then in effect and applicable, for as long as any share of Series A Preferred Stock is outstanding. Redemption of the Series A Preferred Stock is subject to our receipt of any required prior approvals from the Federal Reserve and to the satisfaction of any conditions set forth in the capital guidelines of the Federal Reserve applicable to the redemption of the Series A Preferred Stock.

Redemption Procedures

If shares of the Series A Preferred Stock are to be redeemed, the notice of redemption shall be sent to the holders of record of the Series A Preferred Stock to be redeemed not less than 15 days nor more than 60 days prior to the date fixed for redemption thereof (provided that, if the Depositary Shares representing the Series A Preferred Stock are held in book-entry form through The Depository Trust Company (“DTC”), we may give such notice in any manner permitted by DTC). Each notice of redemption will include a statement setting forth:

•

the redemption date;

•

the number of shares of Series A preferred stock to be redeemed and, if less than all the shares held by the holder are to be redeemed, the number of shares of Series A preferred stock to be redeemed from the holder;

•

the redemption price; and

•

the place or places where the certificates evidencing shares of Series A preferred stock are to be surrendered for payment of the redemption price.

On and after the redemption date, dividends will cease to accrue on shares of Series A Preferred Stock, and such shares of Series A Preferred Stock shall no longer be deemed outstanding and all rights of the holders of such shares will terminate, including the rights described under “— Voting Rights” below, except the right to receive the redemption price plus any declared and unpaid dividends on the shares of Series A preferred stock called for redemption up to the redemption date. See “Description of Depositary Shares” for information about redemption of the Depositary Shares relating to the Series A Preferred Stock.

In case of any redemption of only part of the shares of the Series A Preferred Stock at the time outstanding, the shares to be redeemed shall be selected pro rata or by lot. Subject to the provisions hereof, our Board of Directors shall have full power and authority to prescribe the terms and conditions upon which shares of Series A Preferred Stock shall be redeemed from time to time.

Under the Federal Reserve’s current risk-based capital guidelines applicable to bank holding companies, any redemption of the Series A Preferred Stock is subject to prior approval by the Federal Reserve. Any redemption of the Series A Preferred Stock is subject to our receipt of any required prior approval by the Federal Reserve and to the satisfaction of any conditions set forth in the capital guidelines or regulations of the Federal Reserve applicable to redemption of the Series A Preferred Stock.

Neither the holders of the Series A Preferred Stock nor the holders of the related Depositary Shares have the right to require the redemption or repurchase of the Series A Preferred Stock.

TABLE OF CONTENTS

Liquidation Rights

In the event we liquidate, dissolve or wind-up our business and affairs, either voluntarily or involuntarily, holders of the Series A Preferred Stock are entitled to receive a liquidating distribution of $10,000 per share (equivalent to $25 per Depositary Share), plus any declared and unpaid dividends, without accumulation of any undeclared dividends before we make any distribution of assets to the holders of our common stock or any other class or series of shares ranking junior to the Series A Preferred Stock. Holders of the Series A Preferred Stock will not be entitled to any other amounts from us after they have received their full liquidating distribution.

In any such distribution, if our assets are not sufficient to pay the liquidation preferences plus declared and unpaid dividends in full to all holders of the Series A Preferred Stock and all holders of parity stock, if any, as to such distribution with the Series A Preferred Stock, the amounts paid to the holders of Series A Preferred Stock and parity stock, if any, will be paid pro rata in accordance with the respective aggregate liquidating distribution owed to those holders. If the liquidation preference plus declared and unpaid dividends has been paid in full to all holders of Series A Preferred Stock and parity stock, if any, the holders of our junior stock shall be entitled to receive all of our remaining assets according to their respective rights and preferences.

In addition, we will generally be able to pay dividends and distributions upon liquidation, dissolution or winding up only out of lawfully available assets for such payment (after satisfaction of all claims for indebtedness and other non-equity claims). Further, the Series A Preferred Stock may be fully subordinated to interests held by the U.S. government in the event that we enter into a receivership, insolvency, liquidation, or similar proceeding, including a proceeding under the Orderly Liquidation Authority of the Dodd-Frank Act.

For purposes of this section, the merger or consolidation of us with any other entity, including a merger or consolidation in which the holders of Series A Preferred Stock receive cash, securities or property for their shares, or the sale, lease or exchange of all or substantially all of our assets for cash, securities or other property, shall not constitute a liquidation, dissolution or winding up of Atlantic Union.

Because we are a holding company, our rights and the rights of our creditors and our shareholders, including the holders of the Series A Preferred Stock, to participate in the assets of any of our subsidiaries, including Atlantic Union Bank, upon that subsidiary’s liquidation or recapitalization may be subject to the prior claims of that subsidiary’s creditors, except to the extent that we are a creditor with recognized claims against the subsidiary.

Voting Rights

Except as provided below, the holders of the Series A Preferred Stock will have no voting rights.

Right to Elect Two Directors upon Nonpayment

If we fail to pay, or declare and set apart for payment, dividends on outstanding shares of the Series A Preferred Stock for six quarterly dividend periods, whether or not consecutive, the number of directors on the Board of Directors shall be increased by two at our first annual meeting of the shareholders held thereafter, and at such meeting and at each subsequent annual meeting until continuous noncumulative dividends for at least one year on all outstanding shares of Series A Preferred Stock entitled thereto shall have been paid in full, the holders of shares of Series A Preferred Stock shall have the right, voting as a class together with holders of any other equally ranked series of preferred stock that have similar voting rights, if any, to elect such two additional members of our Board of Directors to hold office for a term of one year; provided that our Board of Directors shall at no time include more than two additional directors elected by holders of shares of Series A Preferred Stock and any other equally ranked series of preferred stock having similar voting rights, if any, voting together as one class. Upon such payment in full, the terms of the two additional directors so elected shall forthwith terminate, and the number of directors shall be reduced by two, and such voting right of the holders of shares of Series A Preferred Stock shall cease, subject to increase in the number of

TABLE OF CONTENTS

directors as described above and to revesting of such voting right in the event of each and every additional failure in the payment of dividends for six quarterly dividend periods, whether or not consecutive, as described above.

In addition, if and when the rights of holders of Series A Preferred Stock terminate for any reason, including under circumstances described above under “— Redemption,” such voting rights shall terminate along with the other rights (except, if applicable, the right to receive the redemption price plus any declared and unpaid dividends), and the terms of any additional directors elected by the holders of Series A Preferred Stock and any other equally ranked series of preferred stock having similar voting rights, if any, shall terminate automatically and the number of directors reduced by two, assuming that the rights of holders of such equally ranked series of preferred stock have similarly terminated.

Under regulations adopted by the Federal Reserve, if the holders of any series of preferred stock are or become entitled to vote separately for the election of directors as a class, such series, along with any other holders of stock that are entitled to vote for the election of directors with that series, will be deemed a class of voting securities. A company holding 25% or more of that class, or less if it otherwise exercises a “controlling influence” over us, will be subject to regulation as a bank holding company under the Bank Holding Company Act of 1956, as amended (the “BHC Act”). In addition, at the time the series is deemed a class of voting securities, any other bank holding company or systemically significant nonbank financial company will be required to obtain the prior approval of the Federal Reserve under the BHC Act to acquire or retain more than 5% of that class. Any other person (other than a bank holding company or systemically significant nonbank financial company) will be required to obtain the non-objection of the Federal Reserve under the Change in Bank Control Act of 1978, as amended, to acquire or retain 10% or more of that class.

Other Voting Rights

So long as any shares of Series A Preferred Stock remain outstanding, the affirmative vote or consent of the holders of at least two-thirds of all outstanding shares of the Series A Preferred Stock, voting separately as a class, shall be required to:

•

authorize or increase the authorized amount of, or issue shares of, any class or series of senior stock, or issue any obligation or security convertible into or evidencing the right to purchase any such shares;

•

amend the provisions of our Amended and Restated Articles of Incorporation so as to adversely affect the powers, preferences, privileges or rights of the Series A Preferred Stock, taken as a whole; provided, however, that any increase in the amount of the authorized or issued Series A Preferred Stock or authorized common stock or preferred stock or the creation and issuance, or an increase in the authorized or issued amount, of other series of preferred stock ranking equally with or junior to the Series A Preferred Stock with respect to the payment of dividends (whether such dividends are cumulative or non-cumulative) or the distribution of assets upon liquidation, dissolution or winding up of Atlantic Union will not be deemed to adversely affect the powers, preferences, privileges or rights of the Series A Preferred Stock; or

•

consummate a binding share-exchange or reclassification involving the Series A Preferred Stock, or a merger or consolidation with or into another entity unless (i) the shares of the Series A Preferred Stock remain outstanding or are converted into or exchanged for preference securities of the new surviving entity and (ii) the shares of the remaining Series A Preferred Stock or new preferred securities have terms that are not materially less favorable than the Series A Preferred Stock.

The foregoing voting provisions will not apply if, at or prior to the time when the act with respect to which such vote would otherwise be required shall be effected, all outstanding shares of Series A Preferred Stock shall have been redeemed.

Voting Rights under Virginia Law

Except as expressly set forth in the Articles of Amendment, the Virginia SCA does not provide any additional voting rights to the holders of the Series A Preferred Stock. Therefore, under the Virginia SCA, the holders of the Series A Preferred Stock will only have those voting rights set forth above under “— Voting Rights.”

TABLE OF CONTENTS

Depositary Agent, Transfer Agent and Registrar

Computershare Trust Company, N.A. is the depositary, and, collectively with Computershare Inc., is the transfer agent and registrar for the Series A Preferred Stock. We may, in our sole discretion, remove the depositary in accordance with the agreement between us and the depositary; provided that we will appoint a successor depositary who will accept such appointment prior to the effectiveness of its removal.

Information Rights

During any period in which we are not subject to Section 13 or 15(d) of the Exchange Act and any shares of the Series A Preferred Stock are outstanding, we will use our best efforts to (i) make available on our website at http://investors.atlanticunionbank.com copies of the annual and quarterly reports that would be required to be filed with the SEC on Forms 10-K and 10-Q, respectively, if we were subject to Section 13 or 15(d) of the Exchange Act (other than any exhibits that would have been required), within the time periods that would apply if we were required to file those reports with the SEC if we were a “non-accelerated filer” within the meaning of the Exchange Act; and (ii) promptly, upon request, supply copies of such reports to any holder or prospective holder of the Series A Preferred Stock. In addition, we will use our best efforts to mail (or otherwise provide) our annual and quarterly reports to all holders of the Series A Preferred Stock, as their names and addresses appear in our record books and without cost to such holders, within 15 days after the respective dates by which a periodic report on Form 10-K or Form 10-Q, as the case may be, would have been required to be filed with the SEC, if we were subject to Section 13 or 15(d) of the Exchange Act, in each case, based on the dates on which we would be required to file such periodic reports if we were a “non-accelerated filer” within the meaning of the Exchange Act.

Preemptive and Conversion Rights

The holders of the Series A Preferred Stock do not have any preemptive or conversion rights.

Form of Series A Preferred Stock

The Series A Preferred Stock has been issued in registered form to the depositary.

TABLE OF CONTENTS

DESCRIPTION OF DEPOSITARY SHARES

Atlantic Union may issue depositary shares representing fractional interests in shares of our preferred stock of any series. The following description sets forth certain general terms and provisions of the depositary shares to which any prospectus supplement may relate. The particular terms of the depositary shares to which any prospectus supplement may relate and the extent, if any, to which the general terms and provisions may apply to the depositary shares so offered will be described in the applicable prospectus supplement. To the extent that any particular terms of the depositary shares, deposit agreements and depositary receipts described in a prospectus supplement differ from any of the terms described below, the terms described below will be deemed to have been superseded by that prospectus supplement. You should read the applicable deposit agreement and depositary receipts for additional information before you decide whether to purchase any of Atlantic Union’s depositary shares.

In connection with the issuance of any depositary shares, Atlantic Union will enter into a deposit agreement with a bank or trust company, as depositary, which will be named in the applicable prospectus supplement. Depositary shares will be evidenced by depositary receipts issued pursuant to the related deposit agreement. Immediately following our issuance of our preferred stock represented by the depositary shares, Atlantic Union will deposit the shares of such preferred stock with the relevant depositary and will cause the depositary to issue, on our behalf, the related depositary receipts. Subject to the terms of the deposit agreement, each owner of a depositary receipt will be entitled, in proportion to the fractional interest in the share of preferred stock represented by the related depositary share, to all the rights, preferences and privileges of, and will be subject to all of the limitations and restrictions on, the preferred stock represented by the depositary receipt (including, if applicable, dividend, voting, conversion, exchange, redemption, sinking fund, subscription and liquidation rights). The applicable prospectus supplement will describe the terms of the depositary shares offered thereby.

Description of Depositary Shares Representing Fractional Interests in Shares of Series A Preferred Stock

The following description summarizes specific terms and provisions of the Depositary Shares relating to the Series A Preferred Stock.

General

The Depositary Shares represent proportional fractional interests in shares of the Series A Preferred stock. Each Depositary Share represents a 1/400th interest in a share of the Series A Preferred Stock, and will be evidenced by depositary receipts. We will deposit the underlying shares of the Series A Preferred Stock with a depositary pursuant to a deposit agreement among us, Computershare Trust Company, N.A., acting as depositary, Computershare Inc. and the holders from time to time of the depositary receipts evidencing the Depositary Shares (the “Deposit Agreement”). Subject to the terms of the Deposit Agreement, each holder of a Depositary Share is entitled, through the depositary, in proportion to the applicable fraction of a share of Series A Preferred Stock represented by such Depositary Share, to all the rights and preferences of the Series A Preferred Stock represented thereby (including dividend, voting, redemption and liquidation rights).

In this prospectus, references to “holders” of Depositary Shares mean those who own Depositary Shares registered in their own names on the books that we or the depositary maintain for this purpose, and not indirect holders who own beneficial interests in Depositary Shares registered in street name or issued in book-entry form through DTC. Please review the special considerations that apply to indirect holders described in the section entitled “Book-Entry Procedures and Settlement.”

Following the issuance of the Series A Preferred Stock, we deposited the Series A Preferred Stock with the depositary, which then issued the Depositary Shares. Copies of the forms of Deposit Agreement and the depositary receipt may be obtained from us upon request and in the manner described in the section entitled “Where You Can Find More Information.”

Dividends and Other Distributions

Each dividend payable on a Depositary Share will be in an amount equal to 1/400th of the dividend declared and payable on the related share of the Series A Preferred Stock.

TABLE OF CONTENTS

The depositary will distribute any cash dividends or other cash distributions received in respect of the deposited Series A Preferred Stock to the record holders of depositary shares relating to the underlying Series A Preferred Stock in proportion to the number of Depositary Shares held by the holders. If we make a distribution other than in cash, the depositary will distribute any property received by it to the record holders of Depositary Shares entitled to those distributions, unless it determines that the distribution cannot be made proportionally among those holders or that it is not feasible to make a distribution. In that event, the depositary may, with our approval, sell the property and distribute the net proceeds from the sale to the holders of the Depositary Shares.

Record dates for the payment of dividends and other matters relating to the Depositary Shares will be the same as the corresponding record dates for the Series A Preferred Stock.

The amounts distributed to holders of Depositary Shares will be reduced by any amounts required to be withheld by the depositary or by us on account of taxes or other governmental charges. The depositary may refuse to make any payment or distribution, or any transfer, exchange, or withdrawal of any Depositary Shares or the shares of the Series A Preferred Stock until such taxes or other governmental charges are paid.

Redemption of Depositary Shares

If we redeem the Series A Preferred Stock represented by the Depositary Shares, the Depositary Shares will be redeemed from the proceeds received by the depositary resulting from the redemption of the Series A Preferred Stock held by the depositary. The redemption price per Depositary Share is expected to be equal to 1/400th of the redemption price per share payable with respect to the Series A Preferred Stock (or $25 per Depositary Share), plus any declared and unpaid dividends.

Whenever we redeem shares of Series A Preferred Stock held by the depositary, the depositary will redeem, as of the same redemption date, the number of Depositary Shares representing shares of Series A Preferred Stock so redeemed. If fewer than all of the outstanding Depositary Shares are redeemed, the depositary will select the Depositary Shares to be redeemed pro rata or by lot. The depositary will send notice of redemption to record holders of the depositary receipts not less than 15 and not more than 60 days prior to the date fixed for redemption of the Series A Preferred Stock and the related Depositary Shares (provided that, if the Depositary Shares representing the Series A Preferred Stock are held in book-entry form through DTC, the depositary may give such notice in any manner permitted by DTC).

Voting the Preferred Stock

Because each Depositary Share represents a 1/400th interest in a share of the Series A Preferred Stock, holders of depositary receipts will be entitled to 1/400th of a vote per Depositary Share under those limited circumstances in which holders of the Series A Preferred Stock are entitled to a vote.

When the depositary receives notice of any meeting at which the holders of the Series A Preferred Stock are entitled to vote, the depositary will send the information contained in the notice to the record holders of the Depositary Shares relating to the Series A Preferred Stock. Each record holder of the Depositary Shares on the record date, which will be the same date as the record date for the Series A Preferred Stock, may instruct the depositary to vote the amount of the Series A Preferred Stock represented by the holder’s Depositary Shares. To the extent possible, the depositary will vote the amount of the Series A Preferred Stock represented by Depositary Shares in accordance with the instructions it receives. We have agreed to take all reasonable actions that the depositary determines are necessary to enable the depositary to vote as instructed. If the depositary does not receive specific instructions from the holders of any Depositary Shares representing the Series A Preferred Stock, it will not vote the amount of the Series A Preferred Stock represented by such Depositary Shares.

Depositary Agent, Transfer Agent and Registrar

Computershare Trust Company, N.A. is the depositary and, collectively with Computershare Inc., is the transfer agent and registrar for the Depositary Shares. We may, in our sole discretion, remove the depositary

TABLE OF CONTENTS

in accordance with the agreement between us and the depositary; provided that we will appoint a successor depositary who will accept such appointment prior to the effectiveness of its removal.

Form of Depositary Shares

The Depositary Shares have been issued in book-entry form through DTC, as described in “Book-Entry Procedures and Settlement” below.

Listing of Depositary Shares

The Depositary Shares are listed on the NASDAQ Global Select Market under the symbol “AUBAP.”

Book Entry Procedures and Settlement

We have issued the Depositary Shares under a book-entry system in the form of global depositary receipts. We have registered the global depositary receipts in the name of a nominee for DTC. The global depositary receipts have been deposited with the depositary.

DTC is the only registered holder of the depositary receipts representing the Depositary Shares and is considered the sole owner of the depositary receipts for purposes of the Deposit Agreement.

Global depositary receipts may be transferred, in whole and not in part, only to another nominee of DTC or to a successor of DTC or its nominee. Beneficial interests in the global depositary receipts may be held through the Euroclear System, or Euroclear, and Clearstream Banking, S.A., or Clearstream, each as indirect participants in DTC. Transfers of beneficial interests in the global depositary receipts are subject to the applicable rules and procedures of DTC and its direct and indirect participants, including, if applicable, those of Euroclear and Clearstream, which may change from time to time. DTC has advised us as follows: it is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code, and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds securities that its participants deposit with it. DTC also facilitates the post-trade settlement among participants of sales and other securities transactions in deposited securities through electronic computerized book entry transfers and pledges between participants’ accounts, thereby eliminating the need for physical movement of securities certificates.

Direct participants in DTC’s system include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations. Access to DTC’s system also is available to others such as both U.S. and non- U.S. securities brokers and dealers, banks, trust companies and clearing corporations that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly, which we collectively call indirect participants. Persons that are not participants may beneficially own securities held by or on behalf of DTC only through the participants or the indirect participants. The ownership interests in, and transfers of ownership interests in, each security held by or on behalf of DTC are recorded on the records of the participants and the indirect participants. The rules applicable to DTC and its participants are on file with the SEC.

Ownership of beneficial interests in the global depositary receipts are limited to participants or persons that may hold interests through participants. Ownership of beneficial interests in the global depositary receipts will be shown on, and the transfer of those ownership interests may be effected only through, records maintained by DTC or its nominee (with respect to participants) and the records of participants and indirect participants (with respect to other owners of beneficial interests in the global depositary receipts).

All interests in a global depositary receipt, including those held through Euroclear or Clearstream, may be subject to the procedures and requirements of DTC. Those interests held through Euroclear or Clearstream may also be subject to the procedures and requirements of such systems.

TABLE OF CONTENTS

The laws of some states require that certain purchasers of securities take physical delivery of those securities in definitive form. These laws may impair the ability of holders to transfer beneficial interests in depositary receipts to certain purchasers. Because DTC can act only on behalf of the participants, which in turn act on behalf of the indirect participants, the ability of a person having beneficial interests in a global depositary receipt to pledge such interests to persons that do not participate in the DTC system, or otherwise take actions in respect of such interests, may be affected by the lack of a physical certificate evidencing such interests.

So long as DTC or any successor depositary for a depositary receipt, or any nominee, is the registered holder of such depositary receipt, DTC or such successor depositary or nominee will be considered the sole owner or holder of the Depositary Shares represented by such depositary receipts for all purposes under the Deposit Agreement. Except as set forth below, owners of beneficial interests in a depositary receipt will not be entitled to have Depositary Shares represented by such depositary receipt registered in their names, will not receive or be entitled to receive physical delivery of Depositary Shares or depositary receipts in definitive form, and will not be considered the owners or holders thereof for any purpose under the Deposit Agreement. Accordingly, each person owning a beneficial interest in a depositary receipt must rely on the procedures of DTC and, if such person is not a participant, on the procedures of the participant through which such person owns its interest, to exercise any rights of a holder under the Deposit Agreement. We understand that, under existing industry practices, in the event that we request any action of holders or that an owner of a beneficial interest in the depositary receipts desires to give any consent or take any action under the Deposit Agreement, DTC or any successor depositary would authorize the participants holding the relevant beneficial interests to give or take such action or consent, and such participants would authorize beneficial owners owning through such participants to give or take such action or consent or would otherwise act upon the instructions of beneficial owners owning through them.

Payment of dividends, if any, distributions upon liquidation or other distributions with respect to the Depositary Shares that are registered in the name of or held by DTC or any successor depositary or nominee will be payable to DTC or such successor depositary or nominee, as the case may be, in its capacity as registered holder of the global depositary receipts representing the Depositary Shares. Under the terms of the Deposit Agreement, the depositary will treat the persons in whose names the Depositary Shares, including the depositary receipts, are registered as the owners of such securities for the purpose of receiving payments and for all other purposes. Consequently, neither we, nor any depositary, nor any agent of us or any such depositary will have any responsibility or liability for any aspect of the records relating to, or payments made on account of, beneficial ownership interests in the depositary receipts, for maintaining, supervising or reviewing any records relating to such beneficial ownership interests, or for any other matter relating to the actions and practices of DTC or any of its participants or indirect participants.

We have been advised by DTC that its current practice, upon receipt of any payment of dividends, distributions upon liquidation or other distributions with respect to the depositary receipts, is to credit participants’ accounts with payments on the payment date, unless DTC has reason to believe it will not receive payments on such payment date. Each relevant participant is credited with an amount proportionate to its beneficial ownership of an interest in the relevant security as shown on the records of DTC. Payments by participants and indirect participants to owners of beneficial interests in the global depositary receipts held through such participants and indirect participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of such participants or indirect participants, and will not be the responsibility of us, any depositary, nor any agent of us or of any such depositary. Neither we nor any such depositary or agent will be liable for any delay by DTC or by any participant or indirect participant in identifying the beneficial owners of the Depositary Shares, and we and any such depositary or agent may conclusively rely on and will be protected in relying on instructions from DTC or its nominee for all purposes.

Cross-market transfers between the participants in DTC, on the one hand, and Euroclear or Clearstream participants, on the other hand, will be effected through DTC in accordance with DTC’s rules on behalf of Euroclear or Clearstream, as the case may be, by its depositary; however, such cross-market transactions will require delivery of instructions to Euroclear or Clearstream, as the case may be, by the counterparty in such system in accordance with the rules and procedures and within the established deadlines (Brussels time) of

TABLE OF CONTENTS

such system. Euroclear or Clearstream, as the case may be, will, if the transaction meets its settlement requirements, deliver instructions to its respective depositary to take action to effect final settlement on its behalf by delivering or receiving interests in the relevant global depositary receipts in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Euroclear participants and Clearstream participants may not deliver instructions directly to the depositories for Euroclear or Clearstream. DTC has advised us that it will take any action permitted to be taken by a holder of Depositary Shares only at the direction of one or more participants to whose account DTC has credited the interests in the global depositary receipts and only in respect of such portion of the aggregate amount of the Depositary Shares as to which such participant or participants has or have given such direction.

We have the right to replace the global depositary receipt with depositary receipts in certificated form. If we exercise such right, we will register the depositary receipts in certificated form in the names of the beneficial owners and distribute such depositary receipts in certificated form to such beneficial owners. Subject to the limitations described below, the holders of the depositary receipts in certificated form will have the right to withdraw the underlying shares of the Series A Preferred Stock from the depositary arrangement upon surrender of such depositary receipts at the corporate trust office of the depositary and upon payment of the taxes, charges, and fees provided for in the Deposit Agreement. Subject to the Deposit Agreement, the holders of such depositary receipts will receive the appropriate number of shares of the Series A Preferred Stock and any money or property represented by the Depositary Shares. You may also request to replace your book-entry depositary receipts with depositary receipts in certificated form registered in your name as beneficial owner.

Only whole shares of the Series A Preferred Stock may be withdrawn. If a holder holds an amount other than a whole multiple of 1,000 Depositary Shares, the depositary will deliver, along with the withdrawn shares of the Series A Preferred Stock, a new depositary receipt evidencing the excess number of Depositary Shares. Holders of withdrawn shares of the Series A Preferred Stock will not be entitled to redeposit those shares or to receive Depositary Shares.

Although DTC, Euroclear and Clearstream have agreed to the foregoing procedures to facilitate transfers of interests in the global securities among participants in DTC, Euroclear and Clearstream, they are under no obligation to perform or to continue to perform such procedures, and may discontinue such procedures at any time. Neither we, nor any depositary, nor any agent of us or of any such depositary will have any responsibility for the performance by DTC, Euroclear or Clearstream or their respective participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

The information in this section, including any description of the operations and procedures of DTC, Euroclear and Clearstream, has been provided solely as a matter of convenience. We do not take any responsibility for the accuracy of this information, and this information is not intended to serve as a representation, warranty or contract modification of any kind. The operations and procedures of DTC, Euroclear and Clearstream are solely within the control of such settlement systems and are subject to changes by them.

DESCRIPTION OF DEBT SECURITIES

The following description of the debt securities sets forth certain general terms that may apply to the debt securities that we may offer under this prospectus. The debt securities may be issued as senior debt securities or subordinated debt securities. Unless otherwise specified in the applicable prospectus supplement, we may issue senior debt securities under a senior indenture (the “senior indenture”), which we will enter into with a trustee to be named in the senior indenture. Prior to issuing any debt securities under such senior indenture, we will select the trustee for the senior indenture (the “senior indenture trustee”) relating to the issuance of senior debt securities, qualify the senior indenture trustee under the Trust Indenture Act and execute such senior indenture. We also may issue subordinated debt securities in one or more series under the Subordinated Indenture, dated December 5, 2016 (the “subordinated indenture”), between us and U.S. Bank National Association, and the related supplemental indenture for such subordinated debt securities. Each of the senior indenture trustee and U.S. Bank National association is referred to as the “indenture trustee,” unless otherwise specified.

The senior indenture and subordinated indenture are sometimes collectively referred to as the “indentures” and individually referred to as an “indenture,” and the senior debt securities and the subordinated debt securities are sometimes referred to as the “debt securities.” The indentures are subject to and governed by the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). The form of senior indenture and the subordinated indenture are incorporated by reference in the registration statement of which this prospectus is a part.

The following summary of the terms of the indentures is subject to, and qualified in its entirety by reference to, the indentures, which contain the full legal text of the matters described in this section, and the description of the specific terms of the debt securities in the applicable prospectus supplement. The following summary is not complete. You should read all of the provisions of the indentures, including the definitions of certain terms.

Since we are a holding company, our right, and accordingly, the right of our creditors and shareholders, including the holders of the securities offered by this prospectus and any prospectus supplement, to participate in any distribution of assets of any of our subsidiaries upon its liquidation, reorganization or similar proceeding is subject to the prior claims of creditors of that subsidiary, except to the extent that our claims as a creditor of the subsidiary may be recognized.

The senior debt securities and, in the case of debt securities in bearer form, any coupons to these securities, will constitute part of our senior debt and, except as otherwise provided in the applicable prospectus supplement, will rank on a parity with all of our other unsecured and unsubordinated debt. The subordinated debt securities and any coupons will constitute part of our subordinated debt and will be subordinate and junior in right of payment to all of our “senior indebtedness” (as defined herein). If this prospectus is being delivered in connection with a series of subordinated debt securities, the accompanying prospectus supplement or the information we incorporate in this prospectus by reference will indicate the approximate amount of senior indebtedness outstanding as of the end of the most recent fiscal quarter.

Payments

We may issue debt securities from time to time in one or more series. The provisions of each indenture may allow us to “reopen” a previous issue of a series of debt securities and issue additional debt securities of that issue. The debt securities may be denominated and payable in U.S. dollars.

Debt securities may bear interest at a fixed rate or a floating rate, which, in either case, may be zero, or at a rate that varies during the lifetime of the debt security. Debt securities may be sold at a substantial discount below their stated principal amount, bearing no interest or interest at a rate which at the time of issuance is below market rates. The applicable prospectus supplement will describe the United States federal income tax consequences and special considerations applicable to any such debt securities.

TABLE OF CONTENTS

Terms Specified in Prospectus Supplement

The debt securities will not be secured by any of our assets. All of the debt securities issued under each of the indentures will rank equally and ratably with any additional debt securities issued under the same indenture.

Registration and Transfer of Debt Securities

Holders may present debt securities for exchange, and holders of registered debt securities may present these securities for transfer, in the manner, at the places and subject to the restrictions stated in the indentures and the debt securities and described in the applicable prospectus supplement. We will provide these services without charge except for any tax or other governmental charge payable in connection with these services and subject to any limitations provided in the applicable indenture.

If any of the securities are to be held in global form, the procedures for transfer of interests in those securities will depend upon the procedures of the depositary for those global securities. See “Description of Global Securities.”

Subordination Provisions

The prospectus supplement relating to any offering of subordinated debt securities will describe the specific subordination provisions. However, unless otherwise noted in the prospectus supplement, subordinated debt securities will be subordinate and junior in right of payment to all of our senior indebtedness, to the extent and in the manner set forth in the subordinated indenture. Pursuant to the subordinated indenture, “senior indebtedness” with respect to any series of subordinated debt securities:

•

has the meaning ascribed to such term in the board resolutions or supplemental indenture establishing such series in accordance with the subordinated debt indenture;

•

and includes all of our:

•

indebtedness for borrowed or purchased money, whether or not evidenced by bonds, debentures, securities, notes or other written instruments;

•

deferred obligations for the payment of the purchase price of property or assets acquired other than in the ordinary course of business;

•

obligations, contingent or otherwise, under letters of credit, bankers acceptances, security purchase facilities and similar transactions;

•

capital lease obligations;

•

obligations with respect to interest rate swap, cap or other agreements, interest rate future or option contracts, currency swap agreements, currency future or option contacts, commodity contracts and other similar agreements;

•

any obligations of the Company to its general creditors, as defined and required by the Federal Reserve under its final Basel III capital rules in 78 F.R. 62018 (Oct. 11, 2013) for subordinated debt to qualify as Tier 2 capital; in each case, whether outstanding on the date this Subordinated Indenture becomes effective, or created, assumed or incurred after that date.

Senior indebtedness excludes any indebtedness that: (a) expressly states that it is junior to, or ranks equally in right of payment with, the subordinated debt securities or the subordinated debt securities of any series; or (b) is identified as junior to, or equal in right of payment with, the subordinated debt securities or the subordinated debt securities of any series in any board resolution or in any supplemental indenture. Senior indebtedness shall continue to be senior indebtedness and be entitled to the benefits of the subordination provisions irrespective of any amendment, modification or waiver of any term of such senior indebtedness.

TABLE OF CONTENTS

The subordinated debt securities will be unsecured and will be subordinate and junior in right of payment, to the extent and in the manner set forth below, to the prior payment in full of all of the Company’s senior indebtedness, as more fully described in the applicable prospectus supplement.

All liabilities of our subsidiary bank and our other subsidiaries, including without limitation our subsidiary bank’s depositors, liabilities to general creditors, and liabilities arising during our subsidiaries’ ordinary course of business or otherwise, will be effectively senior to the subordinated debt securities to the extent of the assets of such subsidiaries.

In the event of any insolvency, bankruptcy, receivership, liquidation, reorganization, readjustment of debt, composition, or other similar proceeding relating to us or our property, any proceeding for the liquidation, dissolution, or other winding up of us, whether voluntary or involuntary and whether or not involving insolvency or bankruptcy proceedings, any assignment by us for the benefit of creditors or any other marshalling of our assets, all of our obligations to holders of our senior indebtedness will be entitled to be paid in full before any payment or distribution, whether in cash, securities or other property, can be made on account of the principal or interest on the subordinated debt securities. Only after payment in full of all amounts owing with respect to senior indebtedness will the holders of the subordinated debt securities, together with the holders of any of our obligations ranking on a parity with the subordinated debt securities, be entitled to be paid from our remaining assets the amounts due and owing on account of unpaid principal of and interest on the subordinated debt securities. In the event and during the continuation of any default in the payment of the principal of, or any premium or interest on any senior indebtedness beyond any applicable grace period with respect to such senior indebtedness, or in the event that any event of default with respect to any senior indebtedness shall have occurred and be continuing permitting the holders of such senior indebtedness (or the trustee or agent on behalf of the holders of such subordinated debt securities), to declare such senior indebtedness due and payable prior to the date on which it would otherwise have become due and payable, unless and until such event of default shall have been cured or waived, or shall have ceased to exist and such acceleration shall have been rescinded or annulled, or in the event any judicial proceeding shall be pending with respect to any such default in payment or event of default, then no payment shall be made by us on account of the principal of, or interest on, the subordinated debt securities.

In the event of our bankruptcy or insolvency, holders of our senior indebtedness may receive more, ratably, and holders of the subordinated debt securities may receive less, ratably, than our other creditors. With respect to the assets of a subsidiary of ours, our creditors (including holders of the subordinated debt securities) are structurally subordinated to the prior claims of creditors of such subsidiary, except to the extent that we may be a creditor with recognized claims against such subsidiary.

The subordinated indentures does not contain any limitation on the amount of senior indebtedness or other obligations ranking senior to or equally with the indebtedness evidenced by the subordinated debt securities that may be hereafter incurred by us or our subsidiaries.

Covenants

Under the indentures we covenant to:

•

pay the principal of, interest on and premium, if any, for the debt securities when due;

•

maintain a place of payment;

•

deposit sufficient funds with any paying agent on or before the due date for any principal, interest or premium, if any;

•

if any series of debt securities provides for the payment of additional amounts, to pay such additional amounts as provided for by the terms of such series of debt securities;

•

deliver an officer’s certificate to the applicable trustee at the end of each fiscal year confirming our compliance with our obligations under each of the indentures;

TABLE OF CONTENTS

•

pay or discharge or cause to be paid or discharged, before any delinquency, (i) all taxes, assessments and governmental charges levied or imposed on us or any of our subsidiary, and (ii) all lawful claims for labor, material and supplies which, if unpaid, might become a lien on our or any of our subsidiary’s property;

•

preserve and keep in full force and effect our corporate existence except as otherwise provided in the indentures; and

•

take such other actions as may be specified in the applicable supplemental indenture for a series of debt securities.

Events of Default

Under the indentures, an event of default will occur with respect to a series of debt securities: (i) if we fail to pay interest on the debt securities of that series as and when due and such failure continues for 30 days; (ii) if we fail to pay the principal of the debt securities of that series as and when due; (iii) if we default in the payment of any sinking fund payment for the debt securities of that series when due; (iv) if we fail to deliver the required debt securities or other rights upon an appropriate conversion or exchange election by any holder of convertible debt securities; (v) if we breach any covenant or agreement applicable to the debt securities of that series and such failure continues for 90 days following notice of the same; (vi) if a court enters an order in an involuntary bankruptcy or insolvency proceeding with respect to us that continues unstayed and in effect for a period of 60 consecutive days; (vii) if we commence a bankruptcy or insolvency proceeding, consent to the entry of an order in an involuntary bankruptcy or insolvency proceeding, consent to the appointment of a receiver, liquidator or similar official, make a general assignment for the benefit of creditors, or fail generally to pay our debts as they become due; or (viii) if any other event of default applicable to such series of debt securities occurs.

Unless the terms of a particular series of debt securities provide otherwise, if an event of default (other than an event of default specified in clauses (vi) or (vii) above) under the indenture occurs and is continuing, then the trustee or the holders of not less than 25% in principal amount of the outstanding debt securities of that series may declare the entire principal amount of all debt securities of that series to be due and immediately payable, together with accrued and unpaid interest thereon, if any.

Unless the terms of a particular series of debt securities provide otherwise, if an event of default specified in clauses (vi) or (vii) above occurs, the entire principal amount of all debt securities of that series (or, if any debt securities of that series are original issue discount debt securities, the portion of the principal amount of such debt securities as may be specified by the terms thereof), together with accrued and unpaid interest thereon, if any, will automatically, and without any declaration or other action on the part of the trustee or any holder, become immediately due and payable.

After a declaration of acceleration or any automatic acceleration under clauses (vi) or (vii) above and before a judgment or decree for payment of the money due has been obtained, the holders of a majority in principal amount outstanding of a series of debt securities may rescind the accelerated payment requirement if all existing events of default with respect to the debt securities of such series, other than the non-payment of the principal of debt securities of that series which have become due solely by such acceleration declaration, have been cured or waived and certain other conditions are satisfied.

Each indenture provides that the trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request, or direction of any of the holders of debt securities, unless such holders shall have provided to the trustee indemnity or security acceptable to the trustee against the costs, expenses and liabilities which may be incurred by it in complying with such request or direction. Subject to certain provisions, the holders of a majority in principal amount of the outstanding debt securities of a series will have the right to direct the time, method, and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee with respect to the debt securities of such series.

TABLE OF CONTENTS

No holder of debt securities shall have any right to institute any proceeding, judicial or otherwise, with respect to the indenture, or for the appointment of a receiver or trustee, or for any other remedy under the indenture, unless:

•

such holder has previously given written notice to the trustee of a continuing default with respect to the debt securities of the applicable series;

•

the holders of not less than 25% in principal amount of the debt securities of such series shall have made written request to the trustee to institute proceedings in respect of such default in its own name as trustee under the indenture;

•

such holder or holders have provided to the trustee indemnity acceptable to the trustee against the costs, expenses, and liabilities which may be incurred in complying with such request;

•

the trustee for 60 days after its receipt of such notice, request, and indemnity has failed to institute any such proceeding; and

•

no direction inconsistent with such written request has been received by the trustee during such 60 day-period by the holders of a majority in principal amount of the outstanding debt securities of such series.

In any event, each indenture provides that no one or more of such holders shall have any right under the indenture to affect, disturb or prejudice the rights of any other holder, or to obtain priority or preference over any of the other holders or to enforce any right under the indenture, except in the manner provided in the indenture and for the equal and ratable benefit of all holders of debt securities of a given series.

The indentures contain a covenant that we will file annually with the trustee a certificate of no default or a certificate specifying any default that exists.

Legal Defeasance and Covenant Defeasance

We may choose to either discharge our obligations under the indenture and the debt securities in a legal defeasance, or to release ourselves from certain or all of our covenant restrictions under the indenture and the debt securities in a covenant defeasance. We may do so, after we irrevocably deposit with the trustee for the benefit of the holders of the debt securities of the applicable series, sufficient cash and/or U.S. government securities to pay the principal of (and premium, if any) and interest and any other sums due on the stated maturity date or a redemption date of the debt securities of such series. If we choose the legal defeasance option, the holders of debt securities of such series will not be entitled to the benefits of the indenture except for certain limited rights, including registration of transfer and exchange of debt securities, replacement of lost, stolen or mutilated debt securities and the right to receive payments of the principal of (and premium, if any) and interest on such debt securities when such payments are due.

We may discharge our obligations under the indenture or release ourselves from covenant restrictions only if we meet certain requirements. Among other things, we must deliver to the trustee an opinion of our legal counsel to the effect that holders of the debt securities of the applicable series will not recognize income, gain or loss for federal income tax purposes as a result of such defeasance and will be subject to federal income tax on the same amount, in the same manner and at the same times, as would have been the case if such deposit and defeasance had not occurred. In the case of legal defeasance only, this opinion must be based on either a ruling received from or published by the Internal Revenue Service or a change in the applicable federal income tax law. We may not have a default under the indenture or the debt securities of the applicable series on the date of deposit and, under certain circumstances, 120 days after such deposit. The discharge may not cause the trustee to have a conflicting interest for purposes of the Trust Indenture Act and may not result in our becoming an investment company in violation of the Investment Company Act of 1940. The discharge may not violate any of our agreements to which we are a party or by which we are bound.

Satisfaction and Discharge

We may discharge our obligations under each indenture and each series of debt securities if: (i) all outstanding debt securities of such series have been delivered for cancellation; (ii) all outstanding debt

TABLE OF CONTENTS

securities of such series have become due and payable or will become due and payable at their stated maturity within one year; or (iii) all outstanding debt securities of such series are scheduled for redemption within one year, and we have irrevocably deposited with the trustee an amount sufficient to pay and discharge the principal of (and premium, if any) and interest on all outstanding debt securities of such series and any other sums due on the stated maturity date or a redemption date.

Modification and Waiver

Each indenture provides that we and the trustee may modify or amend the indenture with, or, in certain cases, without the consent of the holders of a majority in principal amount of outstanding debt securities affected thereby; provided, however, that any modification or amendment may not, without the consent of the holder of each outstanding debt security affected thereby:

•

change the stated maturity of the principal of, or any installment of interest on, any debt security;

•

reduce the principal amount or rate of interest of any debt security;

•

reduce the percentage in principal amount of the outstanding debt securities of a series, the consent of whose holders is required to modify or amend the indenture, for any supplemental indenture, or for any waiver of compliance with certain provisions of the indenture or certain defaults and the consequences thereof under the indenture;

•

impair the right to institute suit for the enforcement of any payment on or with respect to the debt securities of a series; or

•

modify the provisions of the indenture with respect to subordination of the debt securities of a series in a manner adverse to the holders of such debt securities.

In addition, the holders of a majority in principal amount of the outstanding debt securities of a given series may, on behalf of all holders of debt securities of such series, waive compliance by us with certain terms, conditions and provisions of the indenture, as well as any past default and/or the consequences of default, other than any default in the payment of principal or interest or any breach in respect of a covenant or provision that cannot be modified or amended without the consent of the holder of each outstanding debt security of such series.

Consolidation, Merger or Sale

The indentures provide that we may not consolidate with or merge into any other entity or convey, transfer or lease all or substantially all of our assets to another entity unless (i) the successor entity is a corporation, partnership, limited liability company or other entity organized or formed and validly existing under the laws of the United States of America, any State thereof or the District of Columbia and expressly assumes the due and punctual payment of the principal of (and premium, if any) and interest on all the debt securities and the performance of every other covenant of the indenture on our part to be performed or observed; (ii) immediately after giving effect to such transaction and treating any indebtedness that becomes an obligation of ours or any of our subsidiaries as a result of such transaction as having been incurred by us or our subsidiary at the time of such transaction, no event of default, and no event which, after notice or lapse of time or both, would become an event of default, shall have occurred and be continuing; and (iii) the successor entity delivers to the trustee an officer’s certificate and an opinion of counsel, each stating that such transaction complies with the indenture and that all conditions precedent herein provided for relating to such transaction have been complied with.

In case of any such consolidation, merger or sale, the successor entity will succeed to, and be substituted for, us, and may exercise every right and power of ours under the indenture with the same effect as if it had been named as us in the applicable indenture. In the event of such succession and substitution, we will be relieved of all obligations and covenants under the indentures and the debt securities.

Governing Law

The governing law for the senior indenture and the senior debt securities will be agreed upon at execution of such senior indenture. The subordinated indenture and the subordinated debt securities are governed by, and construed in accordance with, the laws of the State of New York.

TABLE OF CONTENTS

The Trustees

The senior indenture trustee will be selected prior to issuing any senior debt securities under the senior indenture.

U.S. Bank National Association is the subordinated indenture trustee under the subordinated indenture. From time to time, we, and some of our subsidiaries, may maintain deposit accounts and conduct other banking transactions, including lending transactions, with the subordinated indenture trustee in the ordinary course of business. Additionally, U.S. Bank National Association serves as trustee under one or more indentures involving our existing debt securities. Upon the occurrence of an event of default, or an event which, after notice or lapse of time or both, would become an event of default under any subordinated debt securities, or upon the occurrence of a default under another indenture under which U.S. Bank National Association serves as trustee, the subordinated indenture trustee may be deemed to have a conflicting interest with respect to the other debt securities as to which we are not in default for purposes of the Trust Indenture Act and, accordingly, may be required to resign as subordinated indenture trustee under the subordinate indenture. In that event, we would be required to appoint a successor subordinated indenture trustee.

DESCRIPTION OF WARRANTS

We may issue warrants for the purchase of shares of common stock or preferred stock, or debt securities. Warrants may be issued independently or together with any shares of common stock or preferred stock or debt securities offered by any prospectus supplement and may be attached to or separate from the shares of common or preferred stock or debt securities. The warrants are to be issued under warrant agreements to be entered into between Atlantic Union and a bank or trust company, as warrant agent, as is named in the prospectus supplement relating to the particular issue of warrants. The warrant agent will act solely as an agent of Atlantic Union in connection with the warrants and will not assume any obligation or relationship of agency or trust for or with any holders of warrants or beneficial owners of warrants.

The following outlines some of the general terms and provisions of the warrants that we may offer from time to time. Further terms of the warrants and the applicable warrant agreement will be stated in the applicable prospectus supplement. The following description and any description of the warrants in a prospectus supplement are not complete and are subject to and qualified in its entirety by reference to the terms and provisions of the warrant agreement, which we will file with the SEC in connection with an issuance of any warrants.

General

If warrants are offered, the prospectus supplement will describe the terms of the warrants, including the following:

•

the offering price;

•

the designation, number of shares and terms of the common stock purchasable upon exercise of the common stock warrants and the price at which such shares of common stock may be purchased upon such exercise;

•

the designation, number of shares and terms of the preferred stock purchasable upon exercise of the preferred stock warrants and the price at which such shares of preferred stock may be purchased upon such exercise;

•

the designation, aggregate principal amount and terms of the debt securities purchasable upon exercise of the debt warrants and the price at which such debt securities may be purchased upon such exercise;

•

a discussion of certain United States federal income tax, accounting and other special considerations, procedures and limitations relating to the warrants; and

•

any other terms of the warrants.

Warrants may be exchanged for new warrants of different denominations.

If in registered form, warrants may be presented for registration of transfer, and may be exercised at the corporate trust office of the warrant agent or any other office indicated in the prospectus supplement. Before the exercise of their warrants, holders of warrants will not have any of the rights of holders of the securities purchasable upon such exercise, including the right to receive payments of principal of, any premium on, or any interest on, the debt securities purchasable upon such exercise or to enforce the covenants in the indenture

TABLE OF CONTENTS

or to receive payments of dividends, if any, on the common stock or preferred stock purchasable upon such exercise or to exercise any applicable right to vote.

Exercise of Warrants

Each warrant will entitle the holder to purchase such number of shares of common stock or preferred stock, or such principal amount of debt securities, at such exercise price as shall in each case be set forth in, or can be calculated according to information contained in, the prospectus supplement relating to the warrant. Warrants may be exercised at such times as are set forth in the prospectus supplement relating to such warrants. After the close of business on the expiration date of the warrants, or such later date to which such expiration date may be extended by Atlantic Union, unexercised warrants will become void.

Subject to any restrictions and additional requirements that may be set forth in the prospectus supplement, warrants may be exercised by delivery to the warrant agent of (i) the certificate evidencing such warrants properly completed and duly executed and (ii) payment as provided in the prospectus supplement of the amount required to purchase the shares of common stock or preferred stock or debt securities purchasable upon such exercise. The exercise price will be the price applicable on the date of payment in full, as set forth in the prospectus supplement relating to the warrants. Upon receipt of such payment and the certificate representing the warrants to be exercised, properly completed and duly executed at the corporate trust office of the warrant agent or any other office indicated in the prospectus supplement, we will, as soon as practicable, issue and deliver the shares of common stock or preferred stock or debt securities purchasable upon such exercise. If fewer than all of the warrants represented by such certificate are exercised, a new certificate will be issued for the remaining amount of warrants.

Additional Provisions

The exercise price payable and the number of shares of common stock or preferred stock purchasable upon the exercise of each stock warrant will be subject to adjustment in certain events, including:

•

the issuance of a stock dividend to holders of common stock or preferred stock, respectively;

•

a combination, subdivision or reclassification of common stock or preferred stock, respectively; or

•

any other event described in the applicable prospectus supplement.

In lieu of adjusting the number of shares of common stock or preferred stock purchasable upon exercise of each stock warrant, we may elect to adjust the number of stock warrants. No adjustment in the number of shares purchasable upon exercise of the stock warrants will be required until cumulative adjustments require an adjustment of at least 1% thereof. We may, at our option, reduce the exercise price at any time. No fractional shares will be issued upon exercise of stock warrants, but we will pay the cash value of any fractional shares otherwise issuable. Notwithstanding the foregoing, in case of any merger, consolidation or sale or conveyance of all or substantially all of the assets of Atlantic Union, the holder of each outstanding stock warrant shall have the right upon the exercise thereof to the kind and amount of shares of stock and other securities and property, including cash, receivable by a holder of the number of shares of common stock or preferred stock into which such stock warrants were exercisable immediately prior thereto.

No Rights as Shareholders

Holders of stock warrants will not be entitled, by virtue of being such holders, to vote, to consent, to receive dividends, to receive notice as shareholders with respect to any meeting of shareholders for the election of directors of Atlantic Union or any other matter, or to exercise any rights whatsoever as shareholders of Atlantic Union.

DESCRIPTION OF GLOBAL SECURITIES

Unless otherwise indicated in the applicable prospectus supplement, we may issue the securities other than common stock in the form of one or more fully registered global securities that will be deposited with a depository or its nominee identified in the applicable prospectus supplement and registered in the name of that depository or its nominee. In those cases, one or more registered global securities will be issued in a denomination or aggregate denominations equal to the portion of the aggregate principal or face amount of the securities to be represented by registered global securities. Unless and until it is exchanged in whole for securities in definitive registered form, a registered global security may not be transferred except as a whole by and among the depository for the registered global security, the nominees of the depository or any successors of the depository or those nominees.

If not described below, any specific terms of the depository arrangement with respect to any securities to be represented by a registered global security will be described in the prospectus supplement relating to those securities. We anticipate that the following provisions will apply to all depository arrangements.

Ownership of beneficial interests in a registered global security will be limited to persons, called participants, that have accounts with the depository or persons that may hold interests through participants. Upon the issuance of a registered global security, the depository will credit, on its book-entry registration and transfer system, the participants’ accounts with the respective principal or face amounts of the securities beneficially owned by the participants. Any dealers, underwriters or agents participating in the distribution of the securities will designate the accounts to be credited.

Ownership of beneficial interests in a registered global security will be shown on, and the transfer of ownership interests will be effected only through, records maintained by the depository, with respect to interests of participants, and on the records of participants, with respect to interests of persons holding through participants. The laws of some states may require that some purchasers of securities take physical delivery of these securities in definitive form. These laws may impair your ability to own, transfer or pledge beneficial interests in registered global securities.

So long as the depository, or its nominee, is the registered owner of a registered global security, that depository or its nominee, as the case may be, will be considered the sole owner or holder of the securities represented by the registered global security for all purposes. Except as described below, owners of beneficial interests in a registered global security will not be entitled to have the securities represented by the registered global security registered in their names, will not receive or be entitled to receive physical delivery of the securities in definitive form and will not be considered the owners or holders of the securities. Accordingly, each person owning a beneficial interest in a registered global security must rely on the procedures of the depository for that registered global security and, if that person is not a participant, on the procedures of the participant through which the person owns its interest, to exercise any rights of a holder under the applicable indenture, warrant agreement or unit agreement. We understand that under existing industry practices, if we request any action of holders or if an owner of a beneficial interest in a registered global security desires to give or take any action that a holder is entitled to give or take, the depository for the registered global security would authorize the participants holding the relevant beneficial interests to give or take that action, and the participants would authorize beneficial owners owning through them to give or take that action or would otherwise act upon the instructions of beneficial owners holding through them.

Payments of principal of, and premium, if any, and interest on, debt securities, and any payments to holders with respect to warrants, units or preferred stock, represented by a registered global security registered in the name of a depository or its nominee will be made to the depository or its nominee, as the case may be, as the registered owner of the registered global security. None of Atlantic Union, the trustees, the warrant agents, the unit agents or any other agent of Atlantic Union, agent of the trustees or agent of the warrant agents or unit agents will have any responsibility or liability for any aspect of the records relating to payments made on account of beneficial ownership interests in the registered global security or for maintaining, supervising or reviewing any records relating to those beneficial ownership interests.

We expect that the depository for any of the securities represented by a registered global security, upon receipt of any payment of principal, premium, interest or other distribution of underlying securities or other

property to holders on that registered global security, will immediately credit participants’ accounts in amounts proportionate to their respective beneficial interests in that registered global security as shown on the records of the depository. We also expect that payments by participants to owners of beneficial interests in a registered global security held through participants will be governed by standing customer instructions and customary practices, as is now the case with the securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of those participants.

If the depository for any of these securities represented by a registered global security is at any time unwilling or unable to continue as depository or ceases to be a clearing agency registered under the Exchange Act, and a successor depository registered as a clearing agency under the Exchange Act is not appointed by us within 90 days, we will issue securities in definitive form in exchange for the registered global security that had been held by the depository. In addition, under the terms of the indenture, we may at any time and in our sole discretion decide not to have any of the securities represented by one or more registered global securities. We understand, however, that, under current industry practices, the depository would notify its participants of our request, but will only withdraw beneficial interests from a global security at the request of each participant. We would issue definitive certificates in exchange for any such interests withdrawn. Any securities issued in definitive form in exchange for a registered global security will be registered in the name or names that the depository gives to the applicable trustee, warrant agent, unit agent or other relevant agent of ours or theirs. It is expected that the depository’s instructions will be based upon directions received by the depository from participants with respect to ownership of beneficial interests in the registered global security that had been held by the depository.

BOOK-ENTRY ISSUANCE

General

The Depository Trust Company (the “DTC”) may act as securities depository for all of the debt securities unless otherwise referred to in the prospectus supplement relating to an offering of debt securities. The debt securities may be issued only as fully-registered securities registered in the name of Cede & Co. (DTC’s nominee). One or more fully-registered global certificates will be issued for the debt securities, representing in the aggregate the total amount of the debt securities, and will be deposited with DTC.

DTC, the world’s largest depository, is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code, and a “clearing agency” registered pursuant to Section 17A of the Exchange Act. DTC holds securities that its participants deposit with DTC. DTC also facilitates the settlement among participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in participants’ accounts, thereby eliminating the need for physical movement of securities certificates. Direct participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations.

DTC is a wholly-owned subsidiary of the Depository Trust & Clearing Corporation (the “DTCC”). DTCC, in turn, is owned by a number of its direct participants and members of the National Securities Clearing Corporation, Government Securities Clearing Corporation, MBS Clearing Corporation and Emerging Markets Clearing Corporation, as well as by the New York Stock Exchange, the NYSE Amex and the Financial Industry Regulatory Authority, Inc.

Access to the DTC system is also available to indirect participants, such as securities brokers and dealers, and banks and trust companies that clear through or maintain custodial relationships with direct participants, either directly or indirectly. The rules applicable to DTC and its participants are on file with the SEC.

Purchases of debt securities within the DTC system must be made by or through direct participants, which will receive a credit for the debt securities on DTC’s records. The ownership interest of each actual purchaser of each debt security, as beneficial owner, is in turn to be recorded on the direct and indirect participants’ records. Beneficial owners will not receive written confirmation from DTC of their purchases, but beneficial owners are expected to receive written confirmations providing details of the transactions, as well as periodic statements of their holdings, from the direct or indirect participants through which the beneficial owners purchased debt securities. Transfers of ownership interests in the debt securities are to be accomplished by entries made on the books of participants acting on behalf of beneficial owners. Beneficial owners will not receive certificates representing their ownership interest in debt securities except if use of the book-entry-only system for the debt securities is discontinued.

The deposit of debt securities with DTC and their registration in the name of Cede & Co. or such other nominee will not effect any change in beneficial ownership. DTC will have no knowledge of the actual beneficial owners of the debt securities; DTC’s records reflect only the identity of the direct participants to whose accounts the debt securities are credited, which may or may not be the beneficial owners. The participants will remain responsible for keeping account of their holdings on behalf of their customers.

The information in this section concerning DTC and DTC’s book-entry system has been obtained from sources that we believe to be reliable, but we assume no responsibility for the accuracy thereof. We do not have any responsibility for the performance by DTC or its participants of their respective obligations as described in this prospectus or under the rules and procedures governing their respective operations.

Notices and Voting

Conveyance of notices and other communications by DTC to direct participants, by direct participants to indirect participants, and by direct and indirect participants to beneficial owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.

TABLE OF CONTENTS

Redemption notices will be sent to Cede & Co. as the registered holder of the debt securities. If less than all of the debt securities are being redeemed, DTC’s current practice is to determine by lot the amount of the interest of each direct participant to be redeemed.

Although voting with respect to the debt securities is limited to the holders of record of the debt securities, in those instances in which a vote is required, neither DTC nor Cede & Co. will itself consent or vote with respect to the debt securities. Under its usual procedures, DTC would mail an omnibus proxy to the relevant trustee as soon as possible after the record date. The omnibus proxy assigns Cede & Co.’s consenting or voting rights to those direct participants to whose accounts the debt securities are credited on the record date.

Distribution of Funds

The relevant trustee will make distribution payments on the debt securities to DTC. DTC’s practice is to credit direct participants’ accounts on the relevant payment date in accordance with their respective holdings shown on DTC’s records unless DTC has reason to believe that it will not receive payments on the payment date. Payments by participants to beneficial owners will be governed by standing instructions and customary practices and will be the responsibility of the participant and not of DTC, the relevant trustee or us, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of distributions to DTC is the responsibility of the relevant trustee, disbursement of the payments to direct participants is the responsibility of DTC, and disbursements of the payments to the beneficial owners is the responsibility of direct and indirect participants.

Successor Depositories and Termination of Book-Entry System

DTC may discontinue providing its services with respect to any of the debt securities at any time by giving reasonable notice to the relevant trustee or us. If no successor securities depository is obtained, definitive certificates representing the debt securities are required to be printed and delivered. We also have the option to discontinue use of the system of book-entry transfers through DTC (or a successor depository). After an event of default under the indenture, the holders of a majority in liquidation amount of debt securities may determine to discontinue the system of book-entry transfers through DTC. In these events, definitive certificates for the debt securities will be printed and delivered.

PLAN OF DISTRIBUTION

General

We may sell the securities being offered hereby in one or more of the following ways from time to time:

•

through agents to the public or to investors;

•

to underwriters for resale to the public or to investors;

•

directly to investors; or

•

through a combination of any of these methods of sale.

We will set forth in a prospectus supplement the terms of a particular offering of securities, including:

•

the name or names of any agents or underwriters;

•

the purchase price of the securities being offered and the proceeds we will receive from the sale;

•

any over-allotment options under which underwriters may purchase additional securities from us;

•

any agency fees or underwriting discounts and other items constituting agents’ or underwriters’ compensation;

•

any initial public offering price;

•

any discounts or concessions allowed or reallowed or paid to dealers; and

•

any securities exchanges or markets on which such securities may be listed.

Agents

We may designate agents who agree to use their reasonable efforts to solicit purchases of our securities for a period of their appointment or to sell our securities on a continuing basis.

Underwriters

If we use underwriters for a sale of securities, the underwriters will acquire the shares for their own account. The underwriters may resell the securities in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The underwriters may sell the securities directly or through underwriting syndicates by managing underwriters. The obligations of the underwriters to purchase the shares will be subject to the conditions set forth in the applicable underwriting agreement. In a firm commitment underwriting, the underwriters will be obligated to purchase all the shares if they purchase any of the shares. The underwriters may change from time to time any initial public offering price and any discounts or concessions the underwriters allow or reallow or pay to dealers. We may use underwriters with whom we have a material relationship. We will describe the nature of any such relationship in the applicable prospectus supplement naming any such underwriter.

Underwriters, dealers and agents that participate in the distribution of the securities may be underwriters as defined in the Securities Act, and any discounts or commissions they receive may be treated as underwriting discounts and commissions under the Securities Act. We will identify in the applicable prospectus supplement any underwriters, dealers or agents and will describe their compensation.

We may have agreements with the underwriters, dealers and agents to indemnify them against various civil liabilities, including liabilities under the Securities Act, or to contribute payments that the agents, underwriters, dealers and remarketing firms may be required to make as a result of those civil liabilities. Underwriters, dealers and agents and their affiliates may be customers of, engage in transactions with, or perform services for us or our subsidiaries in the ordinary course of their businesses. In connection with the distribution of the securities, we may enter into swap or other hedging transactions with, or arranged by,

TABLE OF CONTENTS

underwriters, agents or their affiliates. These underwriters, agents or their affiliates may receive compensation, trading gain or other benefits from these transactions.

In compliance with the guidelines of the Financial Industry Regulatory Authority, Inc. (“FINRA”), the aggregate maximum discount, commission or agency fees or other items constituting underwriting compensation to be received by any FINRA member or independent broker-dealer will not exceed 8% of the proceeds from any offering pursuant to this prospectus and any applicable prospectus supplement.

Direct Sales

We may also sell shares directly to one or more purchasers without using underwriters or agents.

Stabilization Activities

Any underwriter may engage in overallotment, stabilizing transactions, short covering transactions and penalty bids in accordance with Regulation M under the Exchange Act. Overallotment involves sales in excess of the offering size, which create a short position. Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum. Short covering transactions involve purchases of the securities in the open market after the distribution is completed to cover short positions. Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the securities originally sold by the dealer are purchased in a covering transaction to cover short positions. Those activities may cause the price of the securities to be higher than it would otherwise be. If commenced, the underwriters may discontinue any of these activities at any time.

Passive Market Making

Any underwriters who are qualified market makers on the NASDAQ Global Select Market may engage in passive market making transactions in the securities on the NASDAQ Global Select Market in accordance with Rule 103 of Regulation M, during the business day prior to the pricing of the offering, before the commencement of offers or sales of the securities. Passive market makers must comply with applicable volume and price limitations and must be identified as passive market makers. In general, a passive market maker must display its bid at a price not in excess of the highest independent bid for such security. If all independent bids are lowered below the passive market maker’s bid, however, the passive market maker’s bid must then be lowered when certain purchase limits are exceeded.

Trading Markets and Listing of Securities

Unless otherwise specified in the applicable prospectus supplement, each class or series of securities will be a new issue with no established trading market, other than our common stock, which is listed on the NASDAQ Global Select Market. Any shares of common stock hereunder will be listed on the NASDAQ Global Select Market. We may elect to list any other class or series of securities on any additional exchange or market, but we are not obligated to do so unless stated otherwise in a prospectus supplement. It is possible that one or more underwriters may make a market in a class or series of securities, but the underwriters will not be obligated to do so and may discontinue any market making at any time without notice. We cannot give any assurance as to the liquidity of the trading market for any of the securities.

General Information

The securities may also be offered and sold, if so indicated in the applicable prospectus supplement, in connection with a remarketing upon their purchase, in accordance with a redemption or repayment pursuant to their terms, or otherwise, by one or more remarketing firms acting as principals for their own accounts or as agents for us. Any remarketing firm will be identified and the terms of its agreement, if any, with us, and its compensation will be described in the applicable prospectus supplement. Remarketing firms may be deemed to be underwriters, as that term is defined in the Securities Act, in connection with the securities remarketed thereby.

EXPERTS

The consolidated financial statements of Atlantic Union Bankshares Corporation appearing in its Annual Report on Form 10-K for the year ended December 31, 2019, and the effectiveness of Atlantic Union Bankshares Corporation’s internal control over financial reporting as of December 31, 2019 have been audited by Ernst & Young LLP, independent registered public accounting firm, as set forth in their reports thereon, included therein, and incorporated herein by reference. Such consolidated financial statements are incorporated herein by reference in reliance upon such reports given on the authority of such firm as experts in accounting and auditing.

With respect to the unaudited condensed consolidated interim financial information of Atlantic Union Bankshares Corporation for the three-month periods ended March 31, 2020 and 2019 and the three and six-month periods ended June 30, 2020 and 2019, incorporated by reference herein, Ernst & Young LLP reported that they have applied limited procedures in accordance with professional standards for a review of such information. However, their separate reports dated May 8, 2020 and August 4, 2020, included in Atlantic Union Bankshares Corporation’s Quarterly Reports on Form 10-Q for the quarters ended March 31, 2020 and June 30, 2020, and incorporated by reference herein, states that they did not audit and they do not express an opinion on that interim financial information. Accordingly, the degree of reliance on their report on such information should be restricted in light of the limited nature of the review procedures applied. Ernst & Young LLP is not subject to the liability provisions of Section 11 of the Securities Act of 1933 (the “Act”) for their reports on the unaudited interim financial information because those reports are not a “report” or a “part” of the Registration Statement prepared or certified by Ernst & Young LLP within the meaning of Sections 7 and 11 of the Act.
