First National (FXNC) S-3Shelf registration

This document is called a prospectus and is part of a registration statement that we have filed with the Securities and Exchange Commission (the “SEC”) using a “shelf” registration process. Under this shelf registration process, we may, from time to time, sell any combination of the securities described in this prospectus in one or more offerings in amounts that we will determine from time to time that do not exceed $50,000,000 in the aggregate.

This prospectus provides you with a general description of the securities we may offer. Each time we sell securities, we will provide a prospectus supplement, information that is incorporated by reference into this prospectus, or other offering material containing specific information about the terms of the securities we are offering. That prospectus supplement, information incorporated by reference, or other offering material may include a discussion of any risk factors or other special considerations that apply to those securities or the specific plan of distribution. The prospectus supplement or information incorporated by reference may add, update or change information in this prospectus. If there is any inconsistency between the information in this prospectus and a prospectus supplement or information incorporated by reference having a later date, you should rely on the information in that prospectus supplement or incorporated information having a later date.

The registration statement containing this prospectus, including exhibits to the registration statement, provides additional information about us and the securities offered under this prospectus and any prospectus supplement. We have filed and plan to continue to file other documents with the SEC that contain information about us and our business. Also, we will file legal documents that control the terms of the securities offered by this prospectus as exhibits to the reports that we file with the SEC. The registration statement and other reports can be found on the SEC Internet site mentioned under the heading “Where You Can Find More Information.”

Unless the context requires otherwise, in this prospectus we use the terms “we,” “us,” “our,” and the “Company” to refer to First National Corporation and its subsidiaries, including First Bank, on a consolidated basis.

An investment in our securities involves risks. Before making an investment decision, you should consider carefully the risks described under “Risk Factors” in the applicable prospectus supplement and in our most recent annual report on Form 10-K and quarterly reports on Form 10-Q, and in all other information appearing in or incorporated by reference into this prospectus and any applicable prospectus supplement. If any of the risks occur, our business, financial condition and operating results may be materially adversely affected. In that event, the trading price of the securities could decline, and you could lose all or part of your investment. For more information, see “Where You Can Find More Information” and “Incorporation of Information that We File with the SEC.”

We make certain forward-looking statements in this prospectus, any applicable prospectus supplement and the documents incorporated by reference in this prospectus that are subject to risks and uncertainties. These forward-looking statements include statements regarding our profitability, liquidity, allowance for loan losses, interest rate sensitivity, market risk, growth strategy, financial and other goals, expectations and other statements that are not historical facts. The words “believes,” “expects,” “may,” “will,” “should,” “projects,” “contemplates,” “anticipates,” “forecasts,” “intends,” or other similar words or terms are intended to identify forward-looking statements.

These forward-looking statements are subject to significant uncertainties because they are based upon or are affected by factors including:

Because of these uncertainties, our actual future results may be materially different from the results indicated by these forward-looking statements. In addition, our past results of operations do not necessarily indicate our future results. You should not place undue reliance on our forward-looking statements. All forward-looking statements speak only as of the date on which such statements were made, and we undertake no obligation to update any statement, to reflect events or circumstances after the date on which such statement is made or to reflect the occurrence of unanticipated events.

As of September 30, 2021, we had total assets of $1.36 billion, net loans of $817.0 million, total deposits of $1.21 billion and shareholders’ equity of $116.9 million.

We intend to use the net proceeds from the sales of the offered securities as set forth in the applicable prospectus supplement.

This prospectus contains summary descriptions of the common stock, preferred stock, debt securities, warrants, purchase contracts, rights or units that may be offered and sold from time to time. These summary descriptions are not meant to be complete descriptions of each security. At the time of an offering and sale, this prospectus together with the accompanying prospectus supplement will contain the material terms of the securities being offered.

As of December 17, 2021, we had 9,000,000 shares of capital stock authorized. This authorized capital stock consisted of:

Each holder of common shares is entitled to one vote per share held on any matter submitted to a vote of shareholders. There are no cumulative voting rights in the election of directors or otherwise.

Holders of common shares are entitled to receive dividends when and as declared by the board of directors out of funds legally available, subject to certain restrictions imposed by state and federal laws and the preferential dividend rights of the preferred stock. First National Corporation is a corporation separate and distinct from First Bank. Since most of First National Corporation’s revenues will be received by it in the form of dividends or interest paid by First Bank, our ability to pay dividends will be subject to certain regulatory restrictions.

Holders of our common shares do not have preemptive rights to purchase additional shares of any class of our stock, and have no conversion or redemption rights.

In the event of our liquidation, dissolution or winding up, the holders of common shares (and the holders of any class or series of stock entitled to participate with the common shares in the distribution of assets) shall be entitled to receive, in cash or in kind, our assets available for distribution remaining after payment or provision for payment of our debts and liabilities and distributions or provision for distributions to holders of the preferred stock having preference over the common shares.

Our board of directors is granted the authority from time to time to issue preferred stock in one or more series and in connection with the creation of any such series to fix by resolution the preferences, limitations and relative rights thereof. As of December 17, 2021, there were 1,000,000 authorized shares of preferred stock, par

The preferences and other terms of any series of preferred stock will be fixed by an amendment to our articles of incorporation designating the terms of that series. The specific terms of a particular series of preferred stock will be described in the prospectus supplement relating to that series, including, where applicable:

The description of the terms of a particular series of preferred stock set forth in the applicable prospectus supplement will not purport to be complete and will be qualified in its entirety by reference to the amendment to our articles of incorporation relating to such series.

Our articles of incorporation and bylaws contain provisions that could make more difficult an acquisition of us by means of a tender offer, a proxy contest or otherwise. These provisions are expected to discourage specific types of coercive takeover practices and inadequate takeover bids as well as to encourage persons seeking to acquire control to first negotiate with us. Although these provisions may have the effect of delaying, deferring or preventing a change in control, we believe that the benefits of increased protection through the potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure the Company outweigh the disadvantages of discouraging these proposals because, among other things, negotiation of such proposals could result in an improvement of their terms.

Our articles of incorporation currently provide that unless previously approved by a majority of directors, the following transactions with a beneficial owner, directly or indirectly, of more than five percent of our outstanding capital stock entitled to vote require approval by at least 80 percent of our outstanding capital stock entitled to vote:

If any of the foregoing transactions is with a corporation, person or entity that is not a beneficial owner, directly or indirectly, of more than five percent of our outstanding capital stock entitled to vote, the affirmative vote of two-thirds of our outstanding capital stock entitled to vote shall be required to approve the transaction.

Our bylaws also prescribe the procedure that a shareholder must follow to nominate directors or to bring other business before shareholders’ meetings. For a shareholder to nominate a candidate for director or to bring other business before a meeting, notice must be received by our Secretary not less than 60 days and not more than 90 days prior to the date of the meeting. Notice of a nomination for director must describe various matters regarding the nominee and the shareholder giving the notice. Notice of other business to be brought before the meeting must include a description of the proposed business, the reasons therefore, and other specified matters regarding the shareholder giving the notice.

As permitted by the Virginia Stock Corporation Act (the “Virginia SCA”), our board of directors may issue shares of preferred stock without shareholder approval. Our board of directors has the flexibility to deter attempts to gain control of us by including extraordinary voting, dividend, redemption or conversion rights in any preferred stock that it may deem appropriate to issue. We currently do not have plans to issue any shares of capital stock except as set forth in this prospectus or in the ordinary course of business under our equity compensation plans.

Under the Virginia SCA, a board of directors may amend or repeal bylaws unless 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 of incorporation do not reserve the power to amend our bylaws to increase or decrease the number of directors exclusively to the shareholders and no bylaw, or amendment thereto, expressly prohibits the board of directors from amending the bylaws to increase or decrease the number of directors. In addition, according to our articles of incorporation and bylaws, the newly created directorships resulting from an increase in the number of authorized directors by not more than two directors shall be filled by the directors then in office. As a result, if faced with an attempt to take control of our board, our directors may increase the size of the board of directors and install directors opposed to the hostile takeover attempt.

Our articles of incorporation currently provide that a director may not be removed from office as a director except by the affirmative vote of the holders of 80% of the shares of our common stock issued, outstanding and entitled to vote.

The Virginia SCA includes two anti-takeover statutes, the Affiliated Transactions Statute and the Control Share Acquisitions Statute.

The Affiliated Transactions 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:

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%, 33 1/3%, and 50% of the outstanding shares may, under certain circumstances, be denied. The voting rights may be denied:

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. Our articles of incorporation and bylaws do not contain such a provision that makes these provisions inapplicable to acquisitions of our stock.

The Virginia SCA stipulates that, unless limited by its articles of incorporation, a Virginia corporation must indemnify a director or officer who was wholly successful, on the merits or otherwise, in the defense of any proceeding to which the director or officer was a party because he or she is or was a director or officer of the corporation, against the expenses incurred by the director or officer in connection with the proceeding. The Virginia SCA permits a corporation to advance funds to a director or officer to pay for or reimburse expenses incurred in any legal proceeding before final disposition of the proceeding, if the director or officer delivers to the corporation a signed written undertaking to repay any funds advanced if he or she is not entitled to mandatory indemnification and it is ultimately determined that he or she did not meet the relevant standard of conduct. A corporation is permitted to indemnify a director or officer against liability incurred in a proceeding if a determination has been made by the disinterested members of the board of directors, special legal counsel or shareholders that the director or officer conducted himself or herself in good faith and otherwise met the required standard of conduct. To meet the relevant standard of conduct, the Virginia SCA provides that the director or officer must have believed, in the case of conduct in his or her official capacity with the corporation, that his or her conduct was in its best interests and, in the case of other conduct, that his or her conduct was at least not opposed to its best interests. In the case of any criminal proceeding, the director or officer must not have had reasonable cause to believe his or her conduct was unlawful. In a proceeding by or in the right of the corporation, no indemnification shall be made in respect of any matter as to which a director or officer is adjudged to be liable to the corporation, except for expenses incurred in connection with the proceeding if it is determined that the director or officer has met the relevant standard of conduct. In any other proceeding, no indemnification shall be made if the director or officer is adjudged liable to the corporation on the basis that he or she improperly received a personal benefit. Corporations are given the power to make any further indemnity, including indemnity with respect to a proceeding by or in the right of the corporation, and to make additional provision for advances and reimbursement of expenses, to any director or officer that may be authorized by the articles of incorporation or any bylaw made by the shareholders, or any resolution adopted, before or after the event, by the shareholders, except an indemnity against willful misconduct or a knowing violation of the criminal law.

We are a Virginia corporation. Our articles of incorporation contain provisions indemnifying our directors and officers to the extent not prohibited by Virginia law. In addition, to the extent not prohibited by Virginia law, our articles of incorporation eliminate the personal liability of our directors and officers to us or our shareholders for monetary damages in excess of $1.00.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 (the “Securities Act”) may be permitted to directors, officers or persons controlling us pursuant to the foregoing provisions, we have been informed that in the opinion of the SEC this type of indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

We may issue senior or subordinated debt securities. 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. If issued, there will be one indenture for senior debt securities and one for subordinated debt securities.

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 United States dollars.

The prospectus supplement will contain, where applicable, the following terms of and other information relating to any offered 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 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.

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. The indenture for any subordinated debt securities will define the applicable “senior indebtedness.” 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.

The applicable prospectus supplement will describe the circumstances under which we may withhold payment of principal of, or any premium or interest on, any subordinated debt securities. In such event, any payment or distribution under the subordinated debt securities, whether in cash, securities or other property, which would otherwise (but for the subordination provisions) be payable or deliverable in respect of the subordinated debt securities, will be paid or delivered directly to the holders of senior indebtedness or their representatives or trustees in accordance with the priorities then existing among such holders as calculated by us until all senior indebtedness has been paid in full. If any payment or distribution under the subordinated debt securities is received by the trustee of any subordinated debt securities in contravention of any of the terms of the subordinated indenture and before all the senior indebtedness has been paid in full, such payment or distribution will be received in trust for the benefit of, and paid over or delivered to, the holders of the senior indebtedness or their representatives or trustees at the time outstanding in accordance with the priorities then existing among such holders as calculated by us for application to the payment of all senior indebtedness remaining unpaid to the extent necessary to pay all such senior indebtedness in full.

The applicable prospectus supplement will contain, where applicable, the following information about any senior debt securities issued under it:

The indenture for any senior debt securities will provide holders of the securities with the terms of remedies if we fail to perform specific obligations, such as making payments on the debt securities or other indebtedness, or if we become bankrupt. Holders should review these provisions and understand which of our actions trigger an event of default and which actions do not. The indenture may provide for the issuance of debt securities in one or more series and whether an event of default has occurred may be determined on a series by series basis. The events of default will be defined under the indenture and described in the prospectus supplement.

The prospectus supplement will also contain a description of the method by which the holders of the outstanding debt securities may annul past declarations of acceleration of, or waive past defaults of, the debt securities.

The indenture will contain a provision entitling the trustee, subject to the duty of the trustee during a default to act with the required standard of care, to be indemnified by the holders of debt securities issued under the

The indenture will provide that no individual holder of debt securities may institute any action against us under the indenture, except actions for payment of overdue principal and interest. The prospectus supplement will contain a description of the circumstances under which a holder may exercise this right.

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

The prospectus supplement will contain a description of our ability to eliminate most or all of our obligations on any series of debt securities prior to maturity provided we comply with the provisions described in the prospectus supplement.

We will also have the ability to discharge all of our obligations, other than as to transfers and exchanges, under any series of debt securities at any time, which we refer to as “defeasance.” We may be released with respect to any outstanding series of debt securities from the obligations imposed by any covenants limiting liens and consolidations, mergers and asset sales, and elect not to comply with those sections without creating an event of default. Discharge under those procedures is called “covenant defeasance.” The conditions we must satisfy to exercise covenant defeasance with respect to a series of debt securities will be described in the applicable prospectus supplement.

The prospectus supplement will contain a description of our ability and the terms and conditions under which, with the applicable trustee, we may enter into supplemental indentures which make certain changes that do not adversely affect in any material respect the interests of the holders of any series without the consent of the holders of debt securities issued under a particular indenture.

The prospectus supplement will contain a description of the method by which we and the applicable trustee, with the consent of the holders of outstanding debt securities, may add any provisions to, or change in any manner or eliminate any of the provisions of, the applicable indenture or modify in any manner the rights of the holders of those debt securities. The prospectus supplement will also describe the circumstances under which we may not exercise on this right without the consent of each holder that would be affected by such change.

We may not amend a supplemental indenture relating to subordinated debt securities to alter the subordination of any outstanding subordinated debt securities without the written consent of each potentially adversely affected holder of subordinated and senior indebtedness then outstanding.

As described in the applicable prospectus supplement, each debt security will be represented by either a certificate issued in definitive registered form or one or more global securities registered in the name of a depositary, or its nominee, in the aggregate principal amount of the series of debt securities. For debt securities issued in global form, the Depository Trust Company (the “DTC”) may act as securities depository for such debt securities unless otherwise referred to in the prospectus supplement relating to an offering of debt securities. Such global debt securities may descbe 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 Securities Exchange Act of 1934, as amended (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

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 affect 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.

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.

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.

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

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.

We may issue warrants to purchase common stock, preferred stock, debt securities or any combination of these securities. We may issue the warrants independently or together with any underlying securities, and the warrants may be attached or separate from the underlying securities. We may also issue a series of warrants under a separate warrant agreement to be entered into between us and a warrant agent. The warrant agent will act solely as our agent in connection with the warrants of such series and will not assume any obligation or relationship of agency for or with holders or beneficial owners of warrants.

The description of the specific terms of warrants, whether issued in a series or not, will be in a prospectus supplement accompanying this prospectus. The specific terms of the warrants as described in a prospectus supplement will supplement and, if applicable, may modify or replace the general terms described in this section. If there are differences between a prospectus supplement and this prospectus, the prospectus supplement will control.

This summary also is subject to and qualified in its entirety by reference to all the provisions of any specific warrant document or agreement, which we will file with the SEC, either as an exhibit to an amendment to the registration statement of which this prospectus is a part or as an exhibit to a current report on Form 8-K. See “Where You Can Find More Information” below for information on how to obtain a copy of a warrant document when it is filed.

When we refer to a series of warrants, we mean all warrants issued as part of the same series under the applicable warrant agreement.

The applicable prospectus supplement may describe the terms of any warrants that we may offer, including the following:

We may issue the warrants in one or more series under one or more warrant agreements, each to be entered into between us and a bank, trust company or other financial institution as warrant agent. We may add, replace or terminate warrant agents from time to time. We may also choose to act as our own warrant agent or may choose one of our subsidiaries to do so.

We will not qualify any warrant agreement as an indenture, and no warrant agent will be required to qualify as a trustee, under the Trust Indenture Act. As a result, holders of warrants issued under a warrant agreement will not have the protection of the Trust Indenture Act with respect to their warrants.

The warrant agent under a warrant agreement will act solely as our agent in connection with the warrants issued under that agreement. The warrant agent will not assume any obligation or relationship of agency or trust for or with any holders of those warrants. Any holder of warrants may, without the consent of any other person, enforce by appropriate legal action, on its own behalf, its right to exercise those warrants in accordance with their terms. Until the warrant is properly exercised, no holder of any warrant will be entitled to any rights of a holder of the warrant property purchasable upon exercise of the warrant.

We may issue the warrants in registered form or bearer form. Warrants issued in registered form – i.e., book-entry – will be represented by a global security registered in the name of a depository, which will be the holder of all the warrants represented by the global security. Those investors who own beneficial interests in a global warrant will do so through participants in the depository’s system, and the rights of these indirect owners will be governed solely by the applicable procedures of the depository and its participants. In addition, we may issue warrants in non-global form – i.e., bearer form. If any warrants are issued in non-global form, warrant certificates may be exchanged for new warrant certificates of different denominations, and holders may exchange, transfer or exercise their warrants at the warrant agent’s office or any other office indicated in the applicable prospectus supplement.

Prior to the exercise of their warrants, holders of warrants will not have any rights of holders of the securities purchasable upon such exercise, including the right to dividend payments, if any, or voting rights of the preferred stock or common stock purchasable upon such exercise, or 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.

A warrant will entitle the holder to purchase for cash an amount of securities at an exercise price that will be stated in, or that will be determinable as described in, the applicable prospectus supplement. Warrants may be exercised at any time up to the close of business on the expiration date set forth in the applicable prospectus supplement. After the close of business on the expiration date, unexercised warrants will become void. Warrants may be redeemed as set forth in the applicable prospectus supplement.

We may redeem any warrant before it is exercised unless the applicable prospectus supplement specifies otherwise. The prospectus supplement will specify one or more redemption prices. It may also specify one or more redemption periods during which the redemption prices relating to the redemption of warrants during those periods will apply. The warrant will be redeemable at our option at any time on or after a date specified in the prospectus supplement or at any other specified time or times. If we redeem the warrant, we will do so at the specified redemption price. If different prices are specified for different redemption periods, the price that we pay will be the price that applies to the redemption period during which the warrant is redeemed.

We may issue purchase contracts, which represent contracts obligating holders to purchase from or sell to us, and obligating us to sell to or purchase from the holders, a specified or variable number of shares of our common stock or preferred stock, or debt securities, as applicable, at a future date or dates. The price per share of common stock or preferred stock, or the price of our debt securities as applicable, may be fixed at the time that the purchase contracts are issued or may be determined by reference to a specific formula contained in the purchase contracts. Any such formula may include anti-dilution provisions to adjust the number of shares of common stock or preferred stock issuable pursuant to the purchase contracts upon certain events. We may issue purchase contracts in distinct series.

The applicable prospectus supplement will describe the terms of any purchase contracts. The following description and any description of purchase contracts in the applicable prospectus supplement is subject to and is qualified in its entirety by reference to the purchase contract agreement and, if applicable, collateral arrangements and depositary arrangements relating to such purchase contracts. We will file these documents with the SEC, either as an exhibit to an amendment to the registration statement of which this prospectus is a part or as an exhibit to a current report on Form 8-K. See “Where You Can Find More Information” below for information on how to obtain a copy of a document when it is filed.

We may issue purchase contracts separately or as part of units, which we describe below. Units may consist of a purchase contract and beneficial interests in other securities described in this prospectus or of third parties, securing the holders’ obligations to purchase from or sell shares to us under the purchase contracts. These other securities may consist of preferred stock or common stock, debt securities, trust preferred securities or debt obligations of third parties, including U.S. treasury securities.

The purchase contracts may require us to make periodic payments to the holders of the purchase contracts or vice versa, and these payments may be unsecured or prefunded on some basis. The purchase contracts may require holders to secure their obligations under those contracts in a specified manner and in certain circumstances we may deliver newly issued prepaid purchase contracts upon release to a holder of any collateral securing such holder’s obligations under the original purchase contract.

The applicable prospectus supplement may contain, where applicable, the following information about the purchase contracts issued under it:

We may distribute rights, which may or may not be transferable, to the holders of our common stock or any series of our preferred stock as of a record date set by our board of directors, at no cost to such holders. Each holder will be given the right to purchase a specified number of whole shares of our common stock or preferred stock for every share of our common stock or a series of preferred stock that the holder thereof owned on such record date, as set forth in the applicable prospectus supplement. Unless otherwise provided in an applicable prospectus supplement, no fractional rights or rights to purchase fractional shares will be distributed in any rights offering. The rights will be evidenced by rights certificates, which may be in definitive or book-entry form. Each right will entitle the holder to purchase shares of our common stock or a series of preferred stock at a rate and price per share to be established by our board of directors, as set forth in the applicable prospectus supplement. If holders of rights wish to exercise their rights, they must do so before the expiration date of the rights offering, as set forth in the applicable prospectus supplement. Upon the expiration date, the rights will expire and will no longer be exercisable, unless, in our sole discretion prior to the expiration date, we extend the rights offering. Although we may issue rights, in our sole discretion, we have no obligation to do so.

The specific terms of any rights, including the period during which the rights may be exercised, the manner of exercising such rights, and the transferability of rights, will be in a prospectus supplement accompanying this prospectus. The specific terms of the rights as described in a prospectus supplement will supplement and, if applicable, may modify or replace the general terms described in this section. If there are differences between a prospectus supplement and this prospectus, the prospectus supplement will control.

This summary also is subject to and qualified in its entirety by reference to all the provisions of the rights, which we will file with the SEC, either as an exhibit to an amendment to the registration statement of which this prospectus is a part or as an exhibit to a current report on Form 8-K, in connection with an issuance of rights to holders of our common stock or any series of our preferred stock. See “Where You Can Find More Information” below for information on how to obtain a copy of a document when it is filed.

Our board of directors will determine the exercise price or prices for the rights based upon a number of factors, including, without limitation, our business prospects; our capital requirements; the price or prices at which an underwriter or standby purchasers may be willing to purchase shares that remain unsold in the rights offering; and general conditions in the securities markets, especially for securities of financial institutions. The subscription price may or may not reflect the actual or long-term fair value of the common stock or preferred stock offered in the rights offering. We provide no assurances as to the market values or liquidity of any rights issued, or as to whether or not the market prices of the common stock or preferred stock subject to the rights will be more or less than the rights’ exercise price during the term of the rights or after the rights expire.

The manner of exercising rights will be set forth in the applicable prospectus supplement. Any subscription agent or escrow agent will be set forth in the applicable prospectus supplement. We will pay all fees charged by any subscription agent and escrow agent in connection with the distribution and exercise of rights. Rights holders will be responsible for paying all other commissions, fees, taxes, or other expenses incurred in connection with their transfer of rights that are transferable. Neither we nor the subscription agent will pay such expenses.

The applicable prospectus supplement will set forth the expiration date and time (“Expiration Date”) for exercising rights. If holders of rights do not exercise their rights prior to such time, their rights will expire and will no longer be exercisable and will have no value.

We will extend the Expiration Date as required by applicable law and may, in our sole discretion, extend the Expiration Date. If we elect to extend the Expiration Date, we will issue a press release announcing such extension prior to the scheduled Expiration Date.

We may withdraw the rights offering at any time prior to the Expiration Date for any reason. We may terminate the rights offering, in whole or in part, at any time before completion of the rights offering if there is any judgment, order, decree, injunction, statute, law or regulation entered, enacted, amended or held to be

Holders of rights will have no rights as shareholders with respect to the shares of common stock or preferred stock for which the rights may be exercised until they have exercised their rights by payment in full of the exercise price and in the manner provided in the prospectus supplement, and such shares of common stock or preferred stock, as applicable, have been issued to such persons. Holders of rights will have no right to revoke their subscriptions or receive their monies back after they have completed and delivered the materials required to exercise their rights and have paid the exercise price to the subscription agent. All exercises of rights are final and cannot be revoked by the holder of rights.

We will not be required to issue any person or group of persons shares of our common stock or preferred stock pursuant to the rights offering if, in our sole opinion, such person would be required to give prior notice to or obtain prior approval from, any state or federal governmental authority to own or control such shares if, at the time the rights offering is scheduled to expire, such person has not obtained such clearance or approval in form and substance reasonably satisfactory to us.

We may enter into one or more separate agreements with one or more standby underwriters or other persons to purchase, for their own account or on our behalf, any shares of our common stock or preferred stock not subscribed for in the rights offering. The terms of any such agreements will be described in the applicable prospectus supplement.

We may issue units comprised of any combination of our preferred stock, common stock, debt securities, warrants and purchase contracts. We will issue each unit so that the holder of the unit is also the holder of each security included in the unit. As a result, the holder of a unit will have the rights and obligations of a holder of each included security. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately, at any time or at any time before a specified date.

We will describe the financial and other specific terms of specific units in the prospectus supplement accompanying this prospectus. The following description and any description of units in the applicable prospectus supplement is subject to and is qualified in its entirety by reference to the unit agreement and, if applicable, collateral arrangements and depositary arrangements relating to such units. We will file these documents with the SEC, either as an exhibit to an amendment to the registration statement of which this prospectus is a part or as an exhibit to a current report on Form 8-K. See “Where You Can Find More Information” below for information on how to obtain a copy of a document when it is filed.

The applicable provisions described in this section, as well as those described under “Description of Capital Stock,” “Description of Debt Securities,” “Description of Warrants” and “Description of Purchase Contracts,” will apply to each unit and to each security included in each unit, respectively.

Any underwriter or agent involved in the offer and sale of the securities will be named in the applicable prospectus supplement.

In some cases, we may also repurchase the securities and reoffer them to the public by one or more of the methods described above. This prospectus and the applicable prospectus supplement may be used in connection with any offering of securities through any of these methods or other methods described in the applicable prospectus supplement. This prospectus and applicable prospectus supplement may also be used by us and our affiliates in connection with offers and sales relating to the initial sale of the securities and any market making transactions in the securities. These transactions may be executed at negotiated prices that are related to prevailing market prices at the time of sale, or at other prices. We and our affiliates may act as principal or agent in these transactions.

The securities (including securities issued or to be issued by us or securities borrowed from third parties in connection with arrangements under which we agree to issue securities to underwriters or their affiliates on a delayed or contingent basis) that we distribute by any of these methods may be sold to the public, in one or more transactions, either:

We may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third parties may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of stock, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of stock. The third parties in such sale transactions will be underwriters and, if not identified in this prospectus, will be identified in the applicable prospectus supplement (or a post-effective amendment).

We or one of our affiliates may loan or pledge securities to a financial institution or other third party that in turn may sell the securities using this prospectus. Such financial institution or third party may transfer its short position to investors in our securities or in connection with a simultaneous offering of other securities offered by this prospectus or otherwise.

We may solicit, or may authorize underwriters, dealers or agents to solicit, offers to purchase securities directly from the public from time to time, including pursuant to contracts that provide for payment and delivery on future dates. We may also designate agents from time to time to solicit offers to purchase securities from the public on our behalf. The prospectus supplement relating to any particular offering of securities will name any agents designated to solicit offers, and will include information about any commissions that we may pay the agents and will describe the material terms of any such delayed delivery arrangements, in that offering. Agents may be deemed to be “underwriters” as that term is defined in the Securities Act.

In connection with the sale of securities, underwriters may receive compensation from us or from purchasers of the securities, for whom they may act as agents, in the form of discounts, concessions or commissions. Underwriters may sell the securities to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers for whom they may act as agents. Underwriters, dealers and agents that participate in the distribution of the

Unless otherwise specified in the applicable prospectus supplement, the securities will be a new issue with no established trading market, other than the common stock. Any common stock sold pursuant to a prospectus supplement will be listed on the Nasdaq Stock Market. We may elect to list our common stock or any of the other securities on an exchange, but are not obligated to do so. If we sell a security offered by this prospectus to an underwriter for public offering or sale, the underwriter may make a market for that security, but the underwriter will not be obligated to do so and may discontinue any market making at any time without notice. Therefore, we cannot give any assurances to you concerning the liquidity of any security offered by this prospectus.

If dealers are utilized in the sale of the securities, we will sell the securities to the dealers as principals. The dealers may then resell the securities to the public at varying prices to be determined by such dealers at the time of resale. The names of the dealers and the terms of the transaction will be set forth in the applicable prospectus supplement.

We may enter into agreements with underwriters, dealers and agents who participate in the distribution of the securities that may entitle these persons to indemnification by us against certain liabilities, including liabilities under the Securities Act, or to contribution with respect to payments which such underwriters, dealers or agents may be required to make. Any agreement in which we agree to indemnify underwriters, dealers and agents against civil liabilities will be described in the applicable prospectus supplement.

In connection with an offering, the underwriters may purchase and sell securities in the open market. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater number of securities than they are required to purchase in an offering. Stabilizing transactions consist of certain bids or purchases of the offered securities or any underlying securities made for the purpose of preventing or retarding a decline in the market price of the securities while an offering is in progress.

These activities by the underwriters may stabilize, maintain or otherwise affect the market price of the securities. As a result, the price of the securities may be higher than the price that otherwise might exist in the open market. If these activities are commenced, they may be discontinued by the underwriters at any time. These transactions may be effected on an exchange or automated quotation system, if the securities are listed on that exchange or admitted for trading on that automated quotation system, or in the over-the-counter market or otherwise.

Unless otherwise specified in the applicable prospectus supplement, Williams Mullen, Richmond, Virginia, our counsel, will pass upon the validity of the securities to be issued by us through this prospectus.

We are subject to the information requirements of the Exchange Act, and we file annual, quarterly and current reports, proxy statements and other information with the SEC. The SEC maintains an Internet site at www.sec.gov that contains reports, proxy and information statements and other information regarding issuers, including us, that electronically file documents with the SEC.

This prospectus is part of a registration statement filed by us with the SEC. Because the rules and regulations of the SEC allow us to omit certain portions of the registration statement from this prospectus, this prospectus does not contain all the information set forth in the registration statement. You may review the registration statement and the exhibits filed with the registration statement for further information regarding us and the securities we may offer. The registration statement and its exhibits are available on the SEC’s Internet site at the address set forth above.

We also maintain an Internet site at www.fbvirginia.com, which contains information relating to us and our business. Information contained on our Internet site is not incorporated by reference into this prospectus, any prospectus supplement or the registration statement unless otherwise stated in this prospectus or any prospectus supplement.

This prospectus incorporates by reference important business and financial information that we file with the SEC and that we are not including in or delivering with this prospectus. As the SEC allows, incorporated documents are considered part of this prospectus, and we can disclose important information to you by referring you to those documents.

We incorporate by reference the documents listed below (other than, in each case, documents or information deemed to have been furnished and not filed in accordance with the SEC’s rules):

We also incorporate by reference all documents to the extent they have been filed with the SEC under Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act (1) after the date of this prospectus and (2) until an offering has been completed. Information in this prospectus supersedes related information in the documents listed above, and information in subsequently filed documents supersedes related information in both this prospectus and the incorporated documents.

You should rely only on the information incorporated by reference or provided in this prospectus or any supplement relating to the offered securities. No one else is authorized to provide you with different information. You should not assume that the information in this prospectus or any supplement is accurate as of any date other than the date on the front of those documents because our business, financial condition and results of operations may have changed since that date.

The following is a summary of the expenses to be incurred by the Registrant in connection with the distribution of the securities registered under this registration statement.

The Virginia Stock Corporation Act (the “Virginia SCA”) stipulates that, unless limited by its articles of incorporation, a Virginia corporation must indemnify a director or officer who was wholly successful, on the merits or otherwise, in the defense of any proceeding to which the director or officer was a party because he or she is or was a director or officer of the corporation, against the expenses incurred by the director or officer in connection with the proceeding. The Virginia SCA permits a corporation to advance funds to a director or officer to pay for or reimburse expenses incurred in any legal proceeding before final disposition of the proceeding, if the director or officer delivers to the corporation a signed written undertaking to repay any funds advanced if he or she is not entitled to mandatory indemnification and it is ultimately determined that he or she did not meet the relevant standard of conduct. A corporation is permitted to indemnify a director or officer against liability incurred in a proceeding if a determination has been made by the disinterested members of the board of directors, special legal counsel or shareholders that the director or officer conducted himself or herself in good faith and otherwise met the required standard of conduct. To meet the relevant standard of conduct, the Virginia SCA provides that the director or officer must have believed, in the case of conduct in his or her official capacity with the corporation, that his or her conduct was in its best interests and, in the case of other conduct, that his or her conduct was at least not opposed to its best interests. In the case of any criminal proceeding, the director or officer must not have had reasonable cause to believe his or her conduct was unlawful. In a proceeding by or in the right of the corporation, no indemnification shall be made in respect of any matter as to which a director or officer is adjudged to be liable to the corporation, except for expenses incurred in connection with the proceeding if it is determined that the director or officer has met the relevant standard of conduct. In any other proceeding, no indemnification shall be made if the director or officer is adjudged liable to the corporation on the basis that he or she improperly received a personal benefit. Corporations are given the power to make any further indemnity, including indemnity with respect to a proceeding by or in the right of the corporation, and to make additional provision for advances and reimbursement of expenses, to any director or officer that may be authorized by the articles of incorporation or any bylaw made by the shareholders, or any resolution adopted, before or after the event, by the shareholders, except an indemnity against willful misconduct or a knowing violation of the criminal law.

The Registrant is a Virginia corporation. The Registrant’s articles of incorporation contain provisions indemnifying its directors and officers to the extent not prohibited by Virginia law. In addition, to the extent not prohibited by Virginia law, the Registrant’s articles of incorporation eliminate the personal liability of its directors and officers to the Registrant or its shareholders for monetary damages in excess of $1.00.

Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in Shenandoah County, Virginia, on this 17th day of December, 2021.

Each of the undersigned hereby appoints Scott C. Harvard and M. Shane Bell, and each of them individually, as attorneys and agents for the undersigned, with full power of substitution, for and in the name, place and stead of the undersigned, to sign and file with the Securities and Exchange Commission under the Securities Act of 1933, as amended, any and all amendments (including post-effective amendments) to this registration statement and any and all applications, instruments and other documents to be filed with the Securities and Exchange Commission pertaining to the registration of securities covered hereby, with full power and authority to do and perform any and all acts and things as may be necessary or desirable in furtherance of such registration.

Pursuant to the requirements of the Securities Act of 1933, this Registration Statement has been signed by the following persons in the capacities and on the dates indicated.
