DESCRIPTION OF CAPITAL STOCK
The following description summarizes the terms of our common stock and preferred stock but does not purport to be complete, and it is qualified in its entirety by reference to the applicable provisions of federal law governing bank holding companies, Mississippi law and our articles of incorporation and bylaws. Our Amended and Restated Articles of Incorporation and Amended and Restated Bylaws, as amended, are incorporated by reference as exhibits to our Annual Report on Form 10-K for the year ended December 31, 2021 of which this Exhibit 4.6 is a part.
Common Stock
Authorized.   The Company has 40,000,000 shares of authorized common stock, $1.00 par value. As of March 3, 2022, there were 20,485,830 shares of common stock issued and outstanding.
Voting Rights; Cumulative Voting.   Pursuant to the Mississippi Business Corporation Act (“MBCA”) and the Amended and Restated Bylaws of the Company, each outstanding share of the Company’s common stock is entitled to one vote on each matter submitted to a vote. Holders of the Company’s common stock do not have cumulative voting rights. Article 2.6 of the Company’s Amended and Restated Bylaws provides that unless otherwise required by MBCA or the articles of incorporation, all classes or series of Company shares entitled to vote generally on a matter shall for that purpose be considered a single voting group.
Classified Board of Directors.   Under Article 10 of the Amended and Restated Articles of Incorporation of the Company, as amended, the board of directors of the Company is divided into three classes — Class I, Class II, and Class III as nearly equal in numbers of directors as possible. Article 3.2 of the bylaws establishes a minimum of nine directors, and a maximum of 25 directors. At present there are a total of ten directors divided as follows: three Class I directors, four Class II directors, and three Class III directors. The terms of the Class I directors will expire at the 2023 Annual Shareholders’ Meeting. The terms of the Class II directors will expire at the 2024 Annual Shareholders’ Meeting. The terms of the Class III directors will expire at the 2022 Annual Shareholders’ Meeting.
Dividends.   The Company is a legal entity separate and distinct from The First. There are various restrictions that limit the ability of The First to finance, pay dividends or otherwise supply funds to the Company or other affiliates. In addition, subsidiary banks of holding companies are subject to certain restrictions under Sections 23A and 23B of the Federal Reserve Act on any extension of credit to the bank holding company or any of its subsidiaries, on investments in the stock or other securities thereof and on the taking of such stock or securities as collateral for loans to any borrower. Further, a bank holding company and its subsidiaries are prohibited from engaging in certain tie-in arrangements in connection with extensions of credit, leases or sales of property, or furnishing of services.
The principal source of funds from which the Company pays cash dividends are the dividends received from its bank subsidiary, The First. Consequently, dividends are dependent upon The First’s earnings, capital needs, and regulatory policies, as well as statutory and regulatory limitations.
Federal and state banking laws and regulations restrict the amount of dividends and loans a bank may make to its parent company.  The Company and The First are subject to various general regulatory policies and requirements relating to the payment of dividends, including requirements to maintain adequate capital above regulatory minimums. The appropriate federal bank regulatory authority may prohibit the payment of dividends where it has determined that the payment of dividends would be an unsafe or unsound practice. The Federal Reserve has indicated that paying dividends that deplete a bank’s capital base to an inadequate level would be an unsound and unsafe banking practice. The Federal Reserve has indicated that depository institutions and their holding companies should generally pay dividends only out of current operating earnings.  Further, under Mississippi law, The First must obtain the non-objection of the Commissioner of the Mississippi Department of Banking and Consumer Finance prior to paying any dividend to the Company.
Preemptive Rights; Liquidation.   The Company’s common stock does not carry any preemptive rights enabling a holder to subscribe for or receive shares of the Company’s common stock. In the event of liquidation, holders of the Company’s common stock are entitled to share in the distribution of assets remaining after payment of debts and expenses and after required payments to holders of the Company’s preferred stock, if any such shares are outstanding. There are no redemption or sinking fund provisions applicable to the Company’s common stock.
​

​
Preferred Stock
Under the terms of the Company’s Amended and Restated Articles of Incorporation, the Company has authorized the issuance of up to 10,000,000 shares of preferred stock, par value $1.00 per share, any part or all of which shares may be established and designated from time to time by the Company’s board of directors by filing an amendment to the articles of incorporation, which is effective without shareholder action, in accordance with the appropriate provisions of the MBCA. The Amended and Restated Articles of Incorporation of the Company authorize the Company’s board of directors to establish one or more series of preferred stock, and to establish such preferences, limitations and relative rights as may be applicable to each series of preferred stock. The issuance of preferred stock and the determination of the terms of preferred stock by the board, while providing flexibility in connection with possible acquisitions and other corporate purposes, could, among other things, adversely affect the voting power of the holders of the Company’s common stock.
Anti-Takeover Provisions
Supermajority Voting Requirements; Business Combinations or Control Share Acquisition.   The MBCA states that in the absence of a greater requirement in the articles of incorporation, a sale, lease, exchange, or other disposition of all, or substantially all, of a corporation’s property requires approval by a majority of the shares entitled to vote on the transaction. The Amended and Restated Articles of Incorporation of the Company do not provide for a greater than majority vote on such a transaction.
The Amended and Restated Articles of Incorporation of the Company include a “control share acquisition” provision requiring any person who plans to acquire a control block of stock (generally defined as more than 10% of all voting power) to obtain approval by the majority vote of disinterested shareholders or the affirmative vote of 75% of eligible members of the board of directors (excluding any director who is proposing or who is a member of a group proposing a control share acquisition) in order to vote the control shares. If a control share acquisition is made without first obtaining this approval, all stock beneficially owned by the acquiring person in excess of 10% will be considered “excess stock” and will not be entitled to vote.
Any person who proposes to make or has made a control share acquisition may deliver a statement to the Comapny describing the person’s background and the control share acquisition and requesting a special meeting of shareholders of the Company to decide whether to grant voting rights to the shares acquired in the control share acquisition. The acquiring person must pay the expenses of this meeting. If no request is made, the voting rights to be accorded the shares acquired in the control share acquisition shall be presented to the next special or annual meeting of the shareholders. If the acquiring person does not deliver his or her statement to the Company, it may elect to repurchase the acquiring person’s shares at fair market value. Control shares acquired in a control share acquisition are not subject to redemption after an acquiring person’s statement has been filed unless the shares are not accorded full voting rights by the shareholders.
Removal of Directors.   Article 11 of the Amended and Restated Articles of Incorporation of the Company provide that no director of the Company may be removed except by the shareholders for cause; provided that directors elected by a particular voting group may be removed only by the shareholders in that voting group for cause. Article 3.3 of the Company’s Bylaws provide further that removal action may only be taken at a shareholders’ meeting for which notice of the removal action has been given. A removed director’s successor may be elected at the same meeting to serve the unexpired term.
Vacancies in the Board of Directors.   Under the Company’s Amended and Restated Bylaws, any vacancy may be filled for the unexpired term by the affirmative vote of a majority of the remaining directors, provided that, if the vacant office was held by a director elected by a particular voting group, only the shares of that voting group or the remaining directors elected by that voting group shall be entitled to fill the vacancy; provided further, that if the vacant office was held by a director elected by a particular voting group, the other remaining directors or director (elected by another voting group or groups) may fill the vacancy during an interim period before the shareholders of the vacated director’s voting group act to fill the vacancy.
Amendment of the Articles of Incorporation or Bylaws.   Under the MBCA, the board of directors has the power to amend or repeal the bylaws of a Mississippi corporation such as the Company, unless such power is expressly reserved for the shareholders. Article 10 of the Company’s Amended and Restated Bylaws provides that the bylaws
​

​
may be amended, altered, or repealed by the board of directors, except with regard to the provisions establishing the number of directors and process for removal of directors, which may only be amended by the affirmative vote of holders of outstanding shares entitled to more than 80% of the votes eligible to be cast on the alteration, amendment, or repeal.
Under the MBCA, amendments to the articles of incorporation that result in dissenters’ rights require the affirmative vote of a majority of the outstanding shares entitled to vote on the amendment. Otherwise, the articles of incorporation may be amended by a majority vote of the shares present at a meeting where a quorum is present.
Special Meetings of Shareholders.   Under the Company’s Amended and Restated Bylaws, special meetings of the shareholders, for any purpose or purposes, may be called by the chairman of the board of directors, the chief executive officer, or the board of directors, or within 75 days of a written request of shareholders holding in the aggregate 10% or more of the total voting power entitled to vote on an issue. Such a request must state the purpose or purposes of the proposed special meeting.
Shareholder Proposals and Nominations.   The Company’s Amended and Restated Bylaws provide procedures that must be followed to properly nominate candidates for election as directors. Director nominations, other than those made by or at the direction of the board of directors, may be made by any shareholder by delivering written notice to the corporate secretary of the Company not less than 50 nor more than 90 days prior to the meeting at which directors are to be elected, provided that the Company has mailed the first notice of the meeting at least 60 days prior to the meeting date. If the Company has not given such notice, shareholder nominations must be submitted within ten days following the earlier of (i) the date that notice of the date of the meeting was first mailed to the shareholders or (ii) the day on which public disclosure of such date was made. The Company’s Amended and Restated Bylaws also require information to be supplied about both the shareholder making such nomination or proposal and the person nominated.
Limitations on Directors’ and Officers’ Liability.   Article 7 of the Amended and Restated Articles of Incorporation of the Company provides that no director of the Company shall be personally liable to the Company or its shareholders for monetary damages for breach of fiduciary duty as a director, except for any appropriation in violation of fiduciary duties of any business opportunity; for acts or omissions not in good faith or involving intentional misconduct or a knowing violation of law; under Section 79-4-8.33 of the MBCA; or for any transaction from which the director derived an improper personal benefit. Article 8 of the Company’s Amended and Restated Bylaws also provides for indemnification of directors and officers.
