Proxy Statement/Prospectus

MERGER PROPOSED — YOUR VOTE IS VERY IMPORTANT

To the Shareholders of Southwest Georgia Financial Corporation:

The boards of directors of The First Bancshares, Inc., or First Bancshares, and Southwest Georgia Financial Corporation, or SGB, have each unanimously approved the acquisition of SGB by First Bancshares. The acquisition will be accomplished pursuant to the terms of an Agreement and Plan of Merger, dated as of December 18, 2019, which we refer to as the merger agreement, by and between First Bancshares and SGB, whereby SGB will be merged with and into First Bancshares, which we refer to as the merger. Immediately following the merger of SGB with and into First Bancshares, Southwest Georgia Bank, a wholly owned bank subsidiary of SGB, will merge with and into First Bancshares’ wholly owned bank subsidiary, The First, A National Banking Association, or The First, with The First as the surviving bank, which we refer to as the bank merger.

Although the number of shares of First Bancshares common stock that SGB shareholders will receive is fixed, the market value of the merger consideration will fluctuate with the market price of First Bancshares common stock and will not be known at the time SGB shareholders vote on the merger. First Bancshares common stock is currently quoted on the NASDAQ Global Market. On December 17, 2019, the last full trading day before the public announcement of the merger agreement, based on the last reported sale price of First Bancshares common stock of $34.50 per share, the exchange ratio represented $34.50 in value for each share of SGB common stock to be converted into First Bancshares common stock. Based on the most recent reported closing sale price of First Bancshares common stock on [ ], 2020 of $[ ] per share, the exchange ratio represented $[ ] in value for each share of SGB common stock to be converted into First Bancshares common stock. Based on the exchange ratio and the number of shares of SGB common stock outstanding, the maximum number of shares of First Bancshares common stock offered by First Bancshares and issuable in the merger is [ ]. We urge you to obtain current market quotations for the price of First Bancshares common stock (trading symbol “FBMS”) and SGB common stock (trading symbol “SGB”).

SGB will hold a special meeting of its shareholders, referred to as the SGB special meeting, where SGB shareholders will be asked to consider and vote upon (1) a proposal to approve the merger agreement, (2) a proposal to approve, on an advisory (non-binding) basis, the compensation that DeWitt Drew may receive in connection with merger pursuant to the termination of his existing agreement with SGB (which we refer to as the compensation proposal) and (3) a proposal to adjourn the SGB special meeting, if necessary or appropriate, to solicit additional proxies in favor of the proposal to approve the merger agreement.

The SGB special meeting will be held at SGB’s office located at Southwest Georgia Bank Administrative Services Building, located at 205 Second Street, S.E., Moultrie, Georgia 31768, on [ ], 2020, at [ ], Eastern Time, subject to any adjournment or postponement thereof.

The merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”). Accordingly, a U.S. holder (as defined below) that exchanges its shares of SGB common stock solely for shares of First Bancshares common stock pursuant to the merger generally will not recognize any gain or loss upon the exchange of shares of SGB common stock for shares of First Bancshares common stock.

Your vote is important. Completion of the merger is subject to the approval of the merger agreement by the shareholders of SGB. Regardless of whether or not you plan to attend the SGB special meeting, please take the time to authorize a proxy to vote your shares in accordance with the instructions contained in this proxy statement/prospectus. If you submit a properly signed proxy card without indicating how you want to vote, your proxy will be counted as a vote “FOR” the proposal to approve the merger agreement, “FOR” the compensation proposal and “FOR” the proposal to adjourn the SGB special meeting, if necessary or appropriate, to solicit additional proxies in favor of the proposal to approve the merger agreement. The failure to vote by submitting your proxy or attending the special meeting and voting in person will have the same effect as a vote against approval of the merger agreement. Submitting a proxy now will not prevent you from being able to vote in person at the SGB special meeting. If you hold your shares in “street name,” through a bank, broker or other nominee, you should instruct your bank, broker or other nominee how to vote in accordance with the voting instruction form you receive from your bank, broker or other nominee.

The board of directors of SGB has determined that the merger agreement and the transactions contemplated thereby, including the merger, are advisable and in the best interests of the shareholders of SGB, has unanimously approved the merger agreement and the merger and unanimously recommends that the shareholders of SGB vote “FOR” the proposal to approve the merger agreement, “FOR” the compensation proposal and “FOR” the proposal to adjourn the SGB special meeting, if necessary or appropriate, to solicit additional proxies in favor of the proposal to approve the merger agreement.

This proxy statement/prospectus describes the SGB special meeting, the merger, the merger agreement, other documents related to the merger and other related matters. Please carefully read this entire proxy statement/prospectus, including “Risk Factors,” beginning on page 21, for a discussion of the risks relating to the proposed merger and owning First Bancshares common stock after the merger. You also can obtain information about First Bancshares and SGB from documents that have been filed with the Securities and Exchange Commission that are incorporated in the proxy statement/prospectus by reference.

If you have any questions concerning the merger, please contact DeWitt Drew, President and Chief Executive Officer, at (229) 985-1120. We look forward to seeing you at the meeting.

By order of the Board of Directors,

DeWitt Drew
President and Chief Executive Officer
Southwest Georgia Financial Corporation

Neither the Securities and Exchange Commission, the Board of Governors of the Federal Reserve System, the Office of the Comptroller of the Currency, the Federal Deposit Insurance Corporation, nor any state securities commission or any other bank regulatory agency has approved or disapproved the securities to be issued in the merger or determined if this proxy statement/prospectus is accurate or adequate.

TABLE OF CONTENTS

QUESTIONS AND ANSWERS

The following are answers to some questions that SGB shareholders may have regarding the proposed transaction between First Bancshares and SGB and the proposals being considered at the SGB special meeting. First Bancshares and SGB urge you to read carefully this entire proxy statement/prospectus, including the annexes, and the documents incorporated by reference into this proxy statement/prospectus, because the information in this section does not provide all the information that might be important to you.

Unless the context otherwise requires, references in this proxy statement/prospectus to: (1) “First Bancshares” refer to The First Bancshares, Inc., a Mississippi corporation, and its affiliates; (2) “The First” refer to The First, A National Banking Association, a national banking association and the wholly owned bank subsidiary of First Bancshares; (3) “SGB” refer to Southwest Georgia Financial Corporation, a Georgia corporation, and its affiliates; and (4) “Southwest Georgia Bank” refer to Southwest Georgia Bank, a Georgia state-chartered bank and the wholly owned bank subsidiary of SGB.

Why am I receiving this proxy statement/prospectus?

First Bancshares and SGB have entered into an Agreement and Plan of Merger, dated as of December 18, 2019, which we refer to as the merger agreement. Pursuant to the merger agreement, SGB will merge with and into First Bancshares, with First Bancshares as the surviving company, which we refer to as the merger. Immediately after the merger, Southwest Georgia Bank, a wholly owned bank subsidiary of SGB, will merge with and into First Bancshares’ wholly owned bank subsidiary, The First, with The First as the surviving bank, which we refer to as the bank merger. A copy of the merger agreement is included in this proxy statement/prospectus as Annex A.

The merger cannot be completed unless, among other things, the majority of the outstanding shares of SGB common stock entitled to vote at the SGB special meeting vote in favor of the proposal to approve the merger agreement, which we refer to as the merger proposal.

SGB is also soliciting proxies from its shareholders with respect to a proposal to approve, on an advisory (non-binding) basis, the compensation that SGB’s named executive officers may receive in connection with the merger.

In addition, SGB is soliciting proxies from its shareholders with respect to a proposal to approve one or more adjournments of the SGB special meeting, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of such adjournment to approve the merger proposal, which we refer to as the adjournment proposal.

This proxy statement/prospectus contains important information about the merger agreement, the merger and the proposals being voted on at the SGB special meeting, and you should read it carefully. This is a proxy statement/prospectus because (1) SGB is soliciting proxies from the SGB shareholders and the proxy statement provides important information about the SGB special meeting to vote on the merger proposal, the compensation proposal and the adjournment proposal, and (2) First Bancshares will issue shares of First Bancshares common stock to holders of SGB common stock in connection with the merger, and the prospectus provides important information about such shares. The enclosed materials allow SGB shareholders to authorize a proxy to vote their shares without attending the SGB special meeting.

Your vote is important. We encourage you to authorize your proxy as soon as possible.

What will I receive in the merger?

If the merger is completed, each share of SGB common stock issued and outstanding immediately prior to the effective time of the merger will be converted into the right to receive 1.00, or the exchange ratio, share of First Bancshares common stock. To the extent that any shares of SGB common stock are subject to vesting restrictions, the same terms and conditions currently applicable to such shares of SGB common stock will continue to apply to the converted shares First Bancshares common stock received in connection with the merger, with certain exceptions where the holder of the shares of

TABLE OF CONTENTS

restricted stock is terminated as an employee of First Bancshares within one year of the completion of the merger (other than for cause, death, disability, normal retirement or voluntary resignation), in which case the converted restricted shares shall immediately vest upon such termination.

SGB may terminate the merger agreement if (i) the average closing price of First Bancshares common stock over the 10 trading days preceding the date that is five days prior to the closing date is less than $26.86, and (ii) the decline in the price of First Bancshares common stock (as measured by the average closing price divided by $33.58) is more than 20% greater than the decline in the KBW Regional Banking Index (KRX) (as measured by dividing the average closing price of the KBW Regional Banking Index over the 10 trading days preceding the date that is five days prior to the closing date by $108.51); provided, however, that First Bancshares has the option, but not the obligation, to adjust the per share cash consideration or the per share stock consideration to prevent the termination of merger agreement.

Will the value of the merger consideration change between the date of this proxy statement/prospectus and the time the merger is completed?

Yes. The value of the merger consideration may fluctuate based upon the market value for First Bancshares common stock between the date of this proxy statement/prospectus and the completion of the merger. SGB shareholders will receive 1.00 share of First Bancshares common stock for each share of SGB common stock they hold. Any fluctuation in the market price of First Bancshares common stock after the date of this proxy statement/prospectus will change the value of the shares of First Bancshares common stock that SGB shareholders may receive.

How does SGB’s board of directors recommend that I vote at the special meeting?

SGB’s board of directors unanimously recommends that you vote “FOR” the merger proposal, “FOR” the compensation proposal and “FOR” the adjournment proposal.

When and where is the SGB special meeting?

The SGB special meeting will be held at the Southwest Georgia Bank Administrative Services Building, located at 205 Second Street, S.E., Moultrie, Georgia 31768, on [ ], 2020, at [ ], Eastern Time.

What do I need to do now?

After you have carefully read this proxy statement/prospectus and have decided how you wish to vote your shares, please authorize a proxy to vote your shares by promptly completing and returning the enclosed proxy card so that your shares are represented and voted at the SGB special meeting. If you are a registered shareholder, you must complete, sign, date and mail your proxy card in the enclosed postage-paid return envelope as soon as possible. If you are a registered shareholder, you may also vote via the Internet or telephone by following the instructions on the proxy card. If you hold your shares in “street name”, through a bank, broker or other holder of record, you must direct your bank, broker or other holder of record how to vote in accordance with the instructions you have received from your bank, broker or other holder of record. A shareholder who holds shares in “street name” through a broker, bank, trustee or other nominee who desires to attend the SGB special meeting in person must bring proof of beneficial ownership as of the record date, such as a letter from the broker, bank, trustee or other nominee that is the record owner of such beneficial owner’s shares, a brokerage account statement or the voting instruction form provided by the broker. Submitting your proxy by mail, voting via the Internet or telephone or directing your bank or broker to vote your shares will ensure that your shares are represented and voted at the SGB special meeting. Your proxy card must be received prior to the special meeting on [ ], 2020, in order to be counted.

What constitutes a quorum for the SGB special meeting?

Holders representing at least a majority of the issued and outstanding shares of SGB common stock entitled to vote at the SGB special meeting must be present, in person or represented by proxy, to

TABLE OF CONTENTS

constitute a quorum. Abstentions and broker non-votes, if any, will be included in determining the number of shares present at the meeting for the purpose of determining the presence of a quorum. If a quorum is not present, the SGB special meeting will be postponed until the holders of the number of shares of SGB common stock required to constitute a quorum attend. If you submit a properly executed proxy card, even if you abstain from voting, your shares of SGB common stock will be counted for purposes of determining whether a quorum is present at the SGB special meeting. If additional votes must be solicited to approve the merger proposal, it is expected that the SGB special meeting will be adjourned to solicit additional proxies.

What is the vote required to approve each proposal?

The merger proposal requires the affirmative vote of a majority of the issued and outstanding shares of SGB common stock entitled to vote at the SGB special meeting. The compensation proposal requires the affirmative vote of a majority of votes cast on the matter. The adjournment proposal requires the affirmative vote of a majority of the votes cast on the matter.

What would happen if the adjournment proposal does not get approved by SGB shareholders?

The completion of the merger is not conditioned upon shareholder approval of the adjournment proposal. If a quorum is present at the SGB special meeting and the adjournment proposal is not approved and there are not sufficient votes at the time of the SGB special meeting to approve the merger proposal, then the SGB board of directors will not have the ability to adjourn to solicit additional votes and the merger proposal will not be approved.

Who may solicit proxies on SGB’s behalf?

In addition to solicitation of proxies by SGB by mail, proxies may also be solicited by SGB’s directors and employees personally, and by telephone, facsimile or other means.

SGB has also made arrangements with Alliance Advisors to assist it in soliciting proxies. For more information on solicitation of proxies in connection with the SGB special meeting, see “SGB Special Meeting — Solicitation of Proxies” beginning on page 32.

Why is my vote important?

If you do not submit a proxy or vote in person, it may be more difficult for SGB to obtain the necessary quorum to hold the special meeting. In addition, your failure to submit a proxy or vote in person, or failure to instruct your bank or broker how to vote, or abstention will have the same effect as a vote against approval of the merger proposal. The merger proposal must be approved by the affirmative vote of the holders of at least a majority of the outstanding shares of SGB common stock. SGB’s board of directors unanimously recommends that you vote “FOR” the merger proposal.

How many votes do I have?

SGB shareholders are entitled to one vote on each proposal to be considered at the special meeting for each share of SGB common stock owned as of the close of business [ ], 2020, which is the record date for the SGB special meeting.

If my shares of common stock are held in “street name” by my bank or broker, will my bank or broker automatically vote my shares for me?

No. Your bank or broker cannot vote your shares without instructions from you. If your shares are held in “street name” through a bank, broker, or other holder of record, you must provide the record holder of your shares with instructions on how to vote the shares. Under the rules of the NYSE American Stock Exchange, if your bank or broker holds your shares (i.e., in “street name”) and delivers this proxy statement/prospectus to you, the bank or broker generally has authority to vote the shares on “routine” matters, even if the broker does not receive instructions from you. However, here, all of the proposals are matters we believe will be considered “non-routine”; therefore, the bank or broker is not entitled to vote your shares without instructions. Please follow the voting instructions

TABLE OF CONTENTS

provided by the bank or broker. You may not vote shares held in “street name” by returning a proxy card directly to SGB, or by voting in person at the SGB special meeting, unless you provide a legal proxy, which you must obtain from your broker, bank, or other holder of record. If you are a SGB “street name” shareholder, failure to instruct your bank, broker, or other holder of record how to vote will have the same effect as a vote “AGAINST” the merger proposal.

How do I vote?

If you are a shareholder of record, you may have your shares of SGB common stock voted on the matters to be presented at the SGB special meeting in any of the following ways:

•

You may vote by mail. You may vote by mail by completing, signing, dating and returning the enclosed proxy card in the accompanying prepaid reply envelope.

•

You may vote by telephone. If you are a registered shareholder, that is, if you hold your stock in your own name, you may vote by telephone by following the instructions included with the proxy card. If you vote by telephone, you do not have to mail in your proxy card.

•

You may vote on the Internet. If you are a registered shareholder, that is, if you hold your stock in your own name, you may vote on the Internet by following the instructions included with the proxy card. If you vote on the Internet, you do not have to mail in your proxy card.

•

You may vote in person at the meeting. You may vote by attending the special meeting and casting your vote in person.

If you are a beneficial owner (i.e., your shares are held in “street name”), please refer to the instructions provided by your bank, brokerage firm or other nominee to see which of the above choices are available to you. Your bank, brokerage firm or other nominee cannot vote your shares without instructions from you. Please note that if you are a beneficial owner and wish to vote in person at the special meeting, you must obtain a legal proxy from your bank, brokerage firm or other nominee.

Do SGB directors and executive officers have interests in the merger that are different from, or in addition to, my interests?

Yes. In considering the recommendation of the SGB board of directors with respect to the merger agreement, you should be aware that SGB’s directors and executive officers have interests in the merger that are different from, or in addition to, the interests of SGB’s shareholders generally. Interests of officers and directors that may be different from or in addition to the interests of SGB’s shareholders include but are not limited to the receipt of continued indemnification and directors’ and officers’ insurance coverage under the merger agreement, conversion of restricted stock awards issued to executive officers and directors, cash payments to be made to one executive officer and a new employment agreement between one executive officer and The First. See “The Merger — Interests of SGB Directors and Executive Officers in the Merger” for a more detailed description of the interests.

What if I abstain from voting, fail to authorize a proxy or fail to vote in person?

If you mark “ABSTAIN” on your proxy with respect to the merger proposal, fail to authorize a proxy or fail to vote in person at the SGB special meeting, or fail to instruct your bank or broker how to vote, it will have the same effect as a vote “AGAINST” the merger proposal and no effect on the compensation proposal or the adjournment proposal. If you sign your proxy but do not indicate your vote, your proxy will be voted “FOR” each proposal.

Can I attend the special meeting and vote my shares in person?

Yes. All SGB shareholders as of the record date, including shareholders of record and shareholders who hold their shares through any other holder of record, are invited to attend the SGB special meeting. Holders of record of SGB common stock can vote in person at the SGB special meeting. If you are not a shareholder of record, you must obtain a proxy, executed in your favor, from the record holder of your shares, such as a broker, bank or other nominee, to be able to vote in person at the SGB special meeting. If you plan to attend the SGB special meeting, you must hold your shares in your own

TABLE OF CONTENTS

name or have a letter from the record holder of your shares confirming your ownership. In addition, you must bring a form of personal photo identification with you in order to be admitted. SGB reserves the right to refuse admittance to anyone without proper proof of share ownership or without proper photo identification. The use of cameras, sound recording equipment, communications devices or any similar equipment during the SGB special meeting is prohibited without express written consent. Even if you plan to attend the special meeting, SGB encourages you to vote by proxy through the mail so your vote will be counted if you later decide not to attend the special meeting.

Can I change my vote?

Yes. If you are a holder of record of SGB common stock, you may revoke your proxy at any time prior to the SGB special meeting by: (1) delivering written notice of revocation to Steve Johnson, Vice President and Secretary, Southwest Georgia Financial Corporation, P.O. Box 3488, Moultrie, Georgia 31776-3488, (2) by returning a duly executed proxy card bearing a later date than the date with which your original proxy card was dated, (3) voting by telephone or on the Internet (your latest telephone or Internet vote will be counted) or (4) by attending the SGB special meeting and voting in person. Your attendance at the SGB special meeting will not constitute automatic revocation of the proxy unless you deliver your ballot in person at the special meeting or deliver a written revocation to the SGB Corporate Secretary prior to the voting of such proxy. If your shares are held in “street name”, you must contact your bank, broker or other nominee and follow its procedures for changing your vote.

Will SGB be required to submit the merger proposal to its shareholders even if SGB’s board of directors has withdrawn, modified or qualified its recommendation?

Yes. Unless the merger agreement is terminated before the SGB special meeting, SGB is required to submit the merger proposal to its shareholders even if SGB’s board of directors has withdrawn, modified or qualified its recommendation.

What are the material U.S. federal income tax consequences of the merger to U.S. holders of shares of SGB common stock?

The merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”), and the merger agreement will constitute a “plan or reorganization” as such term is used in Sections 354 and 361 of the Code. Accordingly, a U.S. holder (as defined below) of SGB common stock that receives only shares of First Bancshares common stock in the merger generally will not recognize gain or loss on the exchange of such holder’s SGB common stock. However, holders of SGB common stock will recognize gain or loss on any cash received in lieu of a fractional share of First Bancshares common stock.

For further information, see “The Merger — Material U.S. Federal Income Tax Consequences.”

The U.S. federal income tax consequences described above may not apply to all holders of SGB common stock. Your particular tax consequences will depend on your individual situation. Accordingly, we strongly urge you to consult your independent tax advisor for a full understanding of the particular tax consequences of the merger to you.

Are SGB shareholders entitled to exercise dissenters’ rights?

No. Holders of record of SGB common stock are not entitled to exercise dissenters’ rights in connection with the merger. For further information, see “The Merger — Dissenters’ Rights.”

Should I send my SGB stock certificates with my proxy card for the SGB special meeting?

No. You should NOT send your SGB stock certificates with your proxy card. First Bancshares, through its appointed exchange agent, will send SGB shareholders separate instructions for exchanging SGB stock certificates and SGB common stock held in book-entry form for the merger consideration.

TABLE OF CONTENTS

What should I do if I hold my shares of SGB common stock in book-entry form?

You are not required to take any specific actions to exchange your shares of SGB common stock if your shares are held in book-entry form. After the completion of the merger, shares of SGB common stock held in book-entry form automatically will be exchanged for the merger consideration, including shares of First Bancshares common stock in book-entry form, and any cash to be paid in lieu of fractional shares in the merger.

How do I vote if I own shares through the Employee Stock Ownership Plan and Trust of Southwest Georgia Financial Corporation?

Participants in the Employee Stock Ownership Plan and Trust of Southwest Georgia Financial Corporation as of the record date of the SGB special meeting have the right to participate in directing the voting of SGB common stock held in their plan accounts as of that date, but do not have the right to vote those shares personally at the SGB special meeting. Such participants should refer to the voting instructions provided by the plan fiduciaries for information on how to direct the voting of such shares.

What happens if I sell or transfer ownership of shares of SGB common stock after the record date for the SGB special meeting?

The record date for the SGB special meeting is earlier than the expected date of completion of the merger. Therefore, if you sell or transfer ownership of your shares of SGB common stock after the record date for the SGB special meeting, but prior to completion of the merger, you will retain the right to vote at the SGB special meeting, but the right to receive the merger consideration will transfer with the shares of SGB common stock.

Whom may I contact if I cannot locate my SGB stock certificate(s)?

If you are unable to locate your original SGB stock certificate(s), you should contact Steve Johnson, Vice President and Secretary at (229) 985-1120. Generally, merger consideration for lost certificates cannot be delivered except upon the making of an affidavit claiming such certificate to be lost, stolen or destroyed and the posting of a bond in such amount as First Bancshares or the exchange agent may determine is reasonably necessary as indemnity against any claim that may be made with respect to such lost certificate.

When do you expect to complete the merger?

First Bancshares and SGB expect to complete the merger in the second quarter of 2020. However, neither First Bancshares nor SGB can assure you when or if the merger will occur. First Bancshares and SGB must first obtain the approval of SGB shareholders for the merger proposal, as well as the necessary regulatory approvals.

What happens if the merger is not completed?

If the merger is not completed, holders of SGB common stock will not receive any consideration for their shares of SGB common stock that otherwise would have been received in connection with the merger. Instead, SGB will remain an independent public company. If the merger is completed but, for any reason, the bank merger is not completed, it will have no impact on the consideration to be received by holders of SGB common stock.

Whom should I call with questions?

If you have any questions concerning the merger agreement, the merger or this proxy statement/prospectus, would like additional copies of this proxy statement/prospectus or need help voting your shares of SGB common stock, please contact Steve Johnson, Vice President and Secretary at (229) 985-1120. You may also contact SGB’s proxy solicitor, Alliance Advisors toll-free at (800) 574-6108.

The Merger

The Merger Agreement (page 61)

Immediately after the merger, Southwest Georgia Bank, a wholly owned banking subsidiary of SGB, will merge with and into First Bancshares’ wholly owned bank subsidiary, The First, with The First as the surviving bank, which we refer to as the bank merger.

Merger Consideration (page 62)

To the extent that any shares of SGB common stock are subject to vesting restrictions, the same terms and conditions currently applicable to such shares of SGB common stock will continue to apply to the converted shares First Bancshares common stock received in connection with the merger, with certain exceptions where the holder of the shares of restricted stock is terminated as an employee of First Bancshares within one year of the completion of the merger (other than for cause, death, disability, normal retirement or voluntary resignation).

On December 17, 2019, the last full trading day before the public announcement of the merger agreement, based on the last reported sale price of First Bancshares common stock of $34.50 per share, the exchange ratio represented $34.50 in value for each share of SGB common stock to be converted into First Bancshares common stock. Based on the most recent reported closing sale price of First Bancshares common stock on [ ], 2020 of $[ ] per share, the exchange ratio represented $[ ] value for each share of SGB common stock to be converted into First Bancshares common stock. Based on the exchange ratio and the number of shares of SGB common stock outstanding, the maximum number of shares of First Bancshares common stock offered by First Bancshares and issuable in the merger is 2,548,510. We urge you to obtain current market quotations for the price of First Bancshares common stock (trading symbol “FBMS”) and SGB common stock (trading symbol “SGB”).

Procedures for Converting Shares of SGB Common Stock into Merger Consideration (page 62)

Risk Factors Related to the Merger (page 25)

Before voting at the SGB special meeting, you should carefully consider all the information contained in or incorporated by reference into this proxy statement/prospectus in deciding how to vote for the proposals presented in the proxy statement/prospectus.

The SGB Special Meeting (page 28)

The special meeting of SGB shareholders will be held on [ ], 2020, at [ ] Eastern Time, at the Southwest Georgia Bank Administrative Services Building, located at 205 Second Street, S.E., Moultrie, Georgia 31768. At the special meeting, SGB shareholders will be asked to:

•

approve the merger proposal;

•

approve the compensation proposal; and

•

approve the adjournment proposal.

Only holders of record at the close of business on [ ], 2020, the SGB record date, will be entitled to vote at the SGB special meeting. Each outstanding share of SGB common stock is entitled to one vote on each proposal to be considered at the SGB special meeting. As of the SGB record date, there were [ ] shares of SGB common stock entitled to vote at the SGB special meeting. All directors of SGB and Southwest Georgia Bank have entered into voting agreements with First Bancshares, pursuant to which they have agreed, solely in their capacity as SGB shareholders, to vote all of their shares of SGB common stock in favor of the proposals to be presented at the SGB special meeting. As of the SGB record date, the directors who are parties to the voting agreements owned and were entitled to vote an aggregate of approximately [ ] shares of SGB common stock, which represented approximately [ ]% of the shares of SGB common stock outstanding on that date. As of the SGB record date, the directors and

TABLE OF CONTENTS

executive officers of SGB and their affiliates beneficially owned and were entitled to vote [ ] shares of SGB common stock, which represented approximately [ ]% of the shares of SGB common stock outstanding on that date. As of the SGB record date, First Bancshares and its subsidiaries did not hold any shares of SGB common stock (other than shares held as fiduciary, custodian or agent), and its directors and executive officers or their affiliates held [ ] shares of SGB common stock.

To approve the merger proposal, the holders of at least a majority of the outstanding shares of SGB common stock entitled to vote on the proposal must vote in favor of the proposal. Your failure to submit a proxy or vote in person at the SGB special meeting, failure to instruct your bank or broker how to vote, or abstention with respect to the merger proposal will have the same effect as a vote against the merger proposal.

The compensation proposal requires the affirmative vote of a majority of the votes cast on such matter.

The adjournment proposal requires the affirmative vote of a majority of the votes cast on such matter.

If you mark “ABSTAIN” on your proxy with respect to the merger proposal, fail to authorize a proxy and fail to vote in person at the SGB special meeting, or fail to instruct your bank or broker how to vote, it will have the same effect as a vote “AGAINST” the merger proposal and no effect on the adjournment proposal. If you sign your proxy but do not indicate your vote, your proxy will be voted “FOR” each proposal.

Recommendation of the SGB Board (page 29)

SGB’s board of directors has determined that the merger, the merger agreement and the transactions contemplated by the merger agreement are advisable and in the best interests of SGB and its shareholders and has unanimously approved the merger, the merger agreement and the transactions contemplated by the merger agreement. SGB’s board of directors unanimously recommends that SGB shareholders vote “FOR” the merger proposal, “FOR” the compensation proposal and “FOR” the adjournment proposal. For the factors considered by SGB’s board of directors in reaching its decision to approve the merger, see “The Merger — SGB’s Reasons for the Merger.”

Board Composition and Management of First Bancshares after the Merger (page 51)

Each of the officers and directors of First Bancshares immediately prior to the effective time of the merger will be the officers and directors of the surviving company from and after the effective time of the merger, until their respective successors have been duly elected, appointed or qualified or until their earlier death, resignation or removal in accordance with the articles of incorporation and bylaws of First Bancshares.

Interests of SGB Directors and Executive Officers in the Merger (page 51)

SGB shareholders should be aware that SGB’s directors and executive officers have interests in the merger and have arrangements that are different from, or in addition to, those of SGB shareholders generally. These interests and arrangements may create potential conflicts of interest. SGB’s board of directors was aware of these interests and considered these interests, among other matters, in adopting and approving the merger agreement and the transactions contemplated by the merger agreement, including the merger, and in recommending that SGB shareholders vote in favor of the merger proposal.

These interests include:

•

the conversion of the SGB restricted stock awards to First Bancshares restricted stock awards;

•

cash payments to be made to one executive officer who has employment agreement with SGB and Southwest Georgia Bank;

•

new employment agreement with First Bancshares and one executive officer of Southwest Georgia Bank; and

•

the right to continued indemnification and directors’ and officers’ liability insurance coverage.

Dissenters’ Rights in the Merger (page 60)

Under Article 13 of the Georgia Business Corporations Code, or GBCC, the law under which SGB is incorporated, SGB shareholders will not be entitled to any dissenters’ rights in connection with the merger.

For further information, see “The Merger — Dissenters’ Rights.”

Conditions to Completion of the Merger (page 74)

Currently, First Bancshares and SGB expect to complete the merger in the second quarter of 2020. As more fully described in this proxy statement/prospectus and in the merger agreement, the completion of the merger depends on a number of conditions being satisfied or, where legally permissible, waived. These conditions include, among others:

•

approval of the merger agreement by the holders of at least a majority of the outstanding shares of SGB common stock entitled to vote at the SGB special meeting;

•

the receipt of all required regulatory approvals for the merger, without the imposition of any material on-going conditions or restrictions, and the expiration of all regulatory waiting periods;

•

the absence of any legal restraint (such as an injunction or restraining order) that would prevent the consummation of the merger;

•

the effectiveness of the registration statement of which this proxy statement/prospectus forms a part;

•

each party’s receipt of a U.S. federal income tax opinion from its outside legal counsel, dated the closing date of the merger, confirming that the merger qualifies as a “reorganization” within the meaning of Section 368(a) of the Code;

•

the Plan of Bank Merger in the form attached as Exhibit B to the merger agreement attached as Annex A to this document being executed and delivered;

•

SGB obtaining an actuarial analysis demonstrating that (i) SGB’s approximate total liability in respect of its pension plan on a termination basis will not materially exceed $13.8 million and (ii) the difference between such liability and the market value of the assets of the pension plan will not be expected to materially exceed $3.85 million; and

•

the absence of the occurrence of a material adverse effect on SGB or First Bancshares.

Neither First Bancshares nor SGB can be certain when, or if, the conditions to the merger will be satisfied or waived, or that the merger will be completed.

Regulatory Approvals Required for the Merger (page 56)

Both First Bancshares and SGB have agreed to use their reasonable best efforts to obtain all regulatory approvals (or waivers) required or advisable to complete the transactions contemplated by the merger agreement. These approvals include, among others, approval from the Board of Governors of the Federal Reserve System, or the Federal Reserve Board, the Office of the Comptroller of the Currency, or the OCC, the Georgia Department of Banking and Finance, or the Georgia Department, and various securities and other regulatory authorities. The U.S. Department of Justice may also review the impact of the merger on competition. First Bancshares and SGB have submitted all applications, waiver requests and notifications to obtain the required regulatory approvals. Although neither First Bancshares nor SGB knows of any reason why these regulatory approvals cannot be obtained, First Bancshares and SGB cannot be certain when or if they will be obtained, as the length of the review process may vary based on, among other things, requests by regulators for additional information or materials.

TABLE OF CONTENTS

No Solicitation (page 71)

Under the merger agreement, SGB has agreed that it will not, and will cause its representatives not to, directly or indirectly, (1) initiate, solicit, induce or knowingly encourage, or take any action to facilitate the making of, any inquiry, offer or proposal which constitutes, or could reasonably be expected to lead to, an acquisition proposal, (2) participate in any discussions or negotiations regarding any acquisition proposal or furnish, or otherwise afford access, to any person (other than First Bancshares) any information or data with respect to SGB or any of its subsidiaries or otherwise relating to an acquisition proposal, (3) release any person from, waive any provisions of, or fail to enforce any confidentiality agreement or standstill agreement to which SGB is a party, or (4) enter into any agreement, confidentiality agreement, agreement in principle or letter of intent with respect to any acquisition proposal or approve or resolve to approve any acquisition proposal or any agreement, agreement in principle or letter of intent relating to an acquisition proposal.

However, prior to obtaining SGB’s required shareholder approval, SGB may, under certain specified circumstances, participate in negotiations or discussions with any third party making an acquisition proposal and provide confidential information to such third party (subject to a confidentiality agreement). SGB must notify First Bancshares promptly (but in no event later than 24 hours) after the receipt of such acquisition proposal.

Additionally, prior to obtaining SGB’s required shareholder approval, SGB may, under certain specified circumstances, withdraw its recommendation to its shareholders with respect to the merger and/or terminate the merger agreement in order to enter into an acquisition agreement with respect to a superior acquisition proposal if it determines in good faith, after consultation with and having considered the advice of outside legal counsel and financial advisors, that such acquisition proposal is a superior proposal and that failure to take such actions more likely than not would cause it to violate its fiduciary duties to SGB’s shareholders under applicable law. However, SGB cannot take any of those actions in response to a superior proposal unless it provides First Bancshares with a five business day period to negotiate in good faith to enable First Bancshares to adjust the terms and conditions of the merger agreement such that it would cause the superior proposal to no longer constitute a superior proposal.

Termination of the Merger Agreement (page 74)

The merger agreement can be terminated at any time prior to completion of the merger by mutual consent, or by either party in the following circumstances:

•

if the merger is not consummated on or before June 30, 2020, subject to automatic extension to August 30, 2020 if the only outstanding condition to closing is the receipt of regulatory approvals;

•

if any regulatory approval required for consummation of the transactions contemplated by the merger agreement has been denied by final non-appealable action by the relevant governmental authority or any application for such regulatory approval shall have been permanently withdrawn at the request of a governmental authority;

•

in the event that approval by the shareholders of SGB is not obtained at a meeting at which a vote was taken; or

•

in the event of a material breach by the other party of any representation, warranty or covenant contained in the merger agreement and such breach is not cured within 30 days.

In addition, First Bancshares may terminate the merger agreement in the following circumstances:

•

if SGB fails to comply in all material respects with its obligations pursuant to the non-solicitation covenants;

•

if SGB withdraws, qualifies, amends, modifies or withholds its recommendation to its shareholders to approve the merger and the merger agreement, or makes any statement, filing or release, in connection with the shareholder meeting or otherwise, inconsistent with its recommendation (it being understood that taking a neutral position or no position with respect to an acquisition proposal shall be considered an adverse modification of its recommendation);

TABLE OF CONTENTS

•

if SGB materially breaches its obligation to call, give notice of, and commence a meeting of shareholders to vote on the merger agreement;

•

if SGB approves or recommends an acquisition proposal (other than the merger agreement proposal);

if SGB resolves or otherwise determines to take, or announces an intention to take, any of the foregoing actions.

In addition, SGB may terminate the merger agreement if:

SGB’s board of directors determines to enter into a definitive agreement with respect to a superior proposal in accordance with the terms of the merger agreement but only if SGB pays to First Bancshares a $3,750,000 termination fee; or

•

(i) the average closing price of First Bancshares common stock over the 10 trading days preceding the date that is five days prior to the closing date is less than $26.86, and (ii) the decline in the price of First Bancshares common stock (as measured by the average closing price divided by $33.58) is more than 20% greater than the decline in the KBW Regional Banking Index (KRX) (as measured by dividing the average closing price of the KBW Regional Banking Index over the 10 trading days preceding the date that is five days prior to the closing date by $108.51); provided, however, that First Bancshares has the option, but not the obligation, to adjust the per share cash consideration or the per share stock consideration to prevent the termination of merger agreement.

Termination Fee (page 75)

If the merger agreement is terminated under certain circumstances, including circumstances involving a change in recommendation by SGB’s board of directors, SGB may be required to pay First Bancshares a termination fee of $3,750,000. The termination fee could discourage other companies from seeking to acquire or merge with SGB.

Expenses (page 76)

Each party will bear all expenses incurred in connection with the merger and the transactions contemplated by the merger agreement.

Material U.S. Federal Income Tax Consequences (page 57)

The merger will be treated as a “reorganization” within the meaning of Section 368(a) of the Code. Accordingly, a U.S. holder (as defined below) of SGB common stock generally will not recognize gain or loss with respect to the receipt of First Bancshares common stock in the merger. However, holders of SGB common stock will recognize gain or loss on the receipt of cash received in lieu of a fractional share of First Bancshares common stock. For further information, see “The Merger — Material U.S. Federal Income Tax Consequences.”

Accounting Treatment of the Merger (page 60)

First Bancshares will account for the merger under the acquisition method of accounting for business combinations under U.S. generally accepted accounting principles, or GAAP.

TABLE OF CONTENTS

The Rights of Holders of SGB Common Stock Will Change as a Result of the Merger (see page 83)

The rights of holders of SGB common stock are governed by Georgia law, as well as SGB’s Articles of Incorporation (which we refer to as the SGB Articles), and SGB’s Bylaws, as amended (which we refer to as the SGB Bylaws). After completion of the merger, the rights of former SGB shareholders will be governed by Mississippi law and by First Bancshares’ Amended and Restated Articles of Incorporation, as amended (which we refer to as the First Bancshares Articles), and First Bancshares’ Amended and Restated Bylaws (which we refer to as the First Bancshares Bylaws).

Material differences between the rights of shareholders of SGB and shareholders of First Bancshares include the process for determining the size of the board of directors, the process for removing directors, limitations of director liability, indemnification of officers, directors and employees, the ability of shareholders to act by written consent, and shareholder proposals and advance notice requirements. The material differences between the organizational documents and the rights of shareholders of SGB and shareholders of First Bancshares are explained in more detail under the section “Comparison of Rights of First Bancshares shareholders and SGB shareholders” beginning on page 83.

Opinion of SGB’s Financial Advisor (page 40 and Annex B)

BSP Securities, LLC which we refer to as BSP, SGB’s financial advisor, delivered its opinion, dated December 18, 2019, to SGB’s board of directors to the effect that, as of the date of the opinion and subject to factors, qualifications, limitations and assumptions set forth in the opinion, the merger consideration was fair, from a financial point of view, to the common shareholders of SGB.

The full text of the written opinion of SGB, which sets forth the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by BSP in connection with its opinion, is attached as Annex B to this proxy statement/prospectus. BSP’s opinion was for the information of, and directed to, SGB’s board of directors (in its capacity as such) in connection with its consideration of the financial terms of the merger. BSP’s opinion is not a recommendation as to how any holder of SGB’s common stock should vote with respect to the proposal to approve the merger agreement or any other matter. It does not address the underlying business decision of SGB to engage in the merger, the relative merits of the merger as compared to any other alternative business strategies that might exist for SGB or the effect of any other transaction in which SGB might engage.

For further information, please see the section entitled “The Merger — Opinion of SGB’s Financial Advisor” beginning on page 40.

Closing and Effective Time of the Merger (see page 61)

The closing date is currently expected to occur in the second quarter of 2020. Simultaneously with the closing of the merger, First Bancshares will file the articles of merger with the Secretary of State of the State of Mississippi and the Secretary of State of the State of Georgia. The merger will become effective at the later of the time the articles of merger are filed or such other time as may be specified in the articles of merger. Neither First Bancshares nor SGB can predict, however, the actual date on which the merger will be completed because it is subject to factors beyond each company’s control, including whether or when the required regulatory approvals and SGB’s shareholder approvals will be received.

We report net interest margin on a fully tax equivalent basis, which calculation is not in accordance with GAAP. The tax equivalent adjustment to net interest income recognizes the income tax savings when comparing taxable and tax-exempt assets and assumes a 25.3% tax rate for 2019-2018 and 34.0% for 2017-2014. Management believes that it is a standard practice in the banking industry to present net interest margin on a fully tax equivalent basis, and believes it enhances the comparability of income and expenses arising from taxable and nontaxable sources. Net interest margin on a fully tax equivalent basis should not be viewed as a substitute for net interest margin provided in accordance with GAAP.

SGB shareholders are advised to obtain current market quotations for First Bancshares common stock and SGB common stock. The market price of First Bancshares common stock will fluctuate between the date of this proxy statement/prospectus and the date of completion of the merger. No assurance can be given concerning the market price of First Bancshares common stock before or after the effective date of the merger. Changes in the market price of First Bancshares common stock prior to the completion of the merger may affect the market value of the merger consideration that SGB shareholders will receive.

Dividends

The principal sources of funds to First Bancshares to pay dividends are the dividends received from The First. Consequently, dividends are dependent upon The First’s earnings, capital needs, 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. Approval by First Bancshares’ regulators is required if the total of all dividends declared in any calendar year exceed the total of its net income for that year combined with its retained net income of the preceding two years. See “Description of Capital Stock — Common Stock — Dividends.”

TABLE OF CONTENTS

RISK FACTORS

In addition to general investment risks and the other information contained in or incorporated by reference into this proxy statement/prospectus, including the matters addressed under the section “Cautionary Statement Concerning Forward-Looking Statements,” you should carefully consider the following risk factors in deciding how to vote for the proposals presented in this proxy statement/prospectus. You should also consider the other information in this proxy statement/prospectus and the other documents incorporated by reference into this proxy statement/prospectus. See “Where You Can Find More Information.”

Risks Related to the Merger

Because of the fixed exchange ratio and the fluctuation of the market price of First Bancshares common stock, SGB shareholders will not know at the time of the special meeting the market value of the merger consideration they will receive at the effective time of the merger.

Pursuant to the merger agreement, each share of SGB common stock issued and outstanding immediately prior to the effective time of the merger will be converted into the right to receive 1.00 share of First Bancshares common stock.

The market value of the merger consideration may vary from the market value on the date SGB and First Bancshares announced the merger, on the date that this proxy statement/prospectus is mailed, on the date of the SGB special meeting and on the date the merger is completed and thereafter due to fluctuations in the market price of First Bancshares common stock. Any fluctuation in the market price of First Bancshares common stock after the date of this proxy statement/prospectus will change the value of the shares of First Bancshares common stock that SGB shareholders may receive. Stock price changes may result from a variety of factors that are beyond the control of First Bancshares and SGB, including but not limited to general market and economic conditions, changes in their respective businesses, operations and prospects and regulatory considerations. Therefore, at the time of the SGB special meeting, SGB shareholders will not know the precise market value of the merger consideration they may receive at the effective time of the merger. In addition, SGB shareholders will not know the exact exchange ratio at the time of the SGB special meeting, as it may be adjusted as a result of the measurement price. SGB shareholders should obtain current sale prices for shares of First Bancshares common stock and SGB common stock before voting their shares at the SGB special meeting.

The merger and related transactions are subject to approval by SGB shareholders.

The merger cannot be completed unless the SGB shareholders approve the merger agreement by the affirmative vote of the holders of at least a majority of the outstanding shares of SGB’s common stock entitled to vote at the SGB special meeting.

Failure to complete the merger could negatively affect the value of the shares and the future business and financial results of SGB.

If the merger is not completed, the ongoing business of SGB could be adversely affected and SGB will be subject to a variety of risks associated with the failure to complete the merger, including the following:

SGB being required, under certain circumstances, to pay to First Bancshares a termination fee equal to $3,750,000;

•

substantial costs incurred by SGB in connection with the proposed merger, such as legal, accounting, financial advisor, printing and mailing fees;

•

the loss of key employees and customers;

•

the disruption of operations and business;

•

deposit attrition, customer loss and revenue loss;

•

unexpected problems with costs, operations, personnel, technology and credit;

•

diversion of management focus and resources from operational matters and other strategic opportunities while working to implement the merger; and

TABLE OF CONTENTS

•

reputational harm due to the adverse perception of any failure to successfully complete the merger.

If the merger is not completed, these risks could materially affect the business, financial results and the value of SGB common stock.

SGB will be subject to business uncertainties and contractual restrictions while the merger is pending.

Uncertainty about the effect of the merger on employees and customers may have an adverse effect on SGB. These uncertainties may impair SGB’s ability to attract, retain and motivate key personnel until the merger is completed, and could cause customers and others that deal with SGB to seek to change existing business relationships with SGB. Retention of certain employees by SGB may be challenging while the merger is pending, as certain employees may experience uncertainty about their future roles with SGB or First Bancshares. If key employees depart because of issues relating to the uncertainty and difficulty of integration or a desire not to remain with SGB or First Bancshares, SGB’s business or the business assumed by First Bancshares following the merger could be harmed. In addition, SGB has agreed to certain contractual restrictions on the operation of its business prior to closing. See “The Merger Agreement — Covenants and Agreements” for a description of the restrictive covenants applicable to SGB.

The merger agreement limits SGB’s ability to pursue an alternative acquisition proposal and requires SGB to pay a termination fee of $3,750,000 under limited circumstances relating to alternative acquisition proposals.

Under the merger agreement, SGB has agreed not to initiate, solicit, induce or knowingly encourage, or take any action to facilitate any alternative business combination transaction or, subject to certain exceptions, participate in discussions or negotiations regarding, or furnish any non-public information relating to, any alternative business combination transaction. See “The Merger Agreement — No Solicitation” on page 71. The merger agreement also provides for SGB to pay to First Bancshares a termination fee in the amount of $3,750,000 in the event that the merger agreement is terminated for certain reasons. See “The Merger Agreement — Termination Fee” on page 75. These provisions could discourage a potential competing acquirer that might have an interest in acquiring SGB from considering or making a competing acquisition proposal, even if the potential competing acquirer was prepared to pay consideration with a higher per share cash value than the market value proposed to be received or realized in the merger, or might result in a potential competing acquirer proposing to pay a lower price than it might otherwise have proposed to pay because of the added expense of the termination fee that may become payable in certain circumstances under the merger agreement.

The merger agreement contains provisions granting both SGB and First Bancshares the right to terminate the merger agreement in certain circumstances.

The merger agreement contains certain termination rights, including the right, subject to certain exceptions, of either party to terminate the merger agreement if the merger is not completed on or prior to June 30, 2020 (subject to automatic extension to August 31, 2020 if the only outstanding condition to closing is the receipt of regulatory approvals), and the right of SGB to terminate the merger agreement, subject to certain conditions, to accept a business combination transaction deemed to be superior to the merger by the SGB board of directors. Additionally, SGB may terminate the agreement if (i) the average closing price of First Bancshares common stock over the 10 trading days preceding the date that is five days prior to the closing date is less than $26.86, and (ii) the decline in the price of First Bancshares common stock (as measured by the average closing price divided by $33.58) is more than 20% greater than the decline in the KBW Regional Banking Index (KRX) (as measured by dividing the average closing price of the KBW Regional Banking Index over the 10 trading days preceding the date that is five days prior to the closing date by $108.51); provided, however, that First Bancshares has the option, but not the obligation, to adjust the per share cash consideration or the per share stock consideration to prevent the termination of merger agreement.

If the merger is not completed, the ongoing business of SGB could be adversely affected and SGB will be subject to several risks, including the risks described elsewhere in this “Risk Factors” section.

The merger is subject to a number of conditions which, if not satisfied or waived in a timely manner, would delay the merger or adversely impact the companies’ ability to complete the transactions.

The completion of the merger is subject to certain conditions, including, among others, the (1) approval of the merger agreement by the holders of at least a majority of the outstanding shares of SGB

TABLE OF CONTENTS

common stock entitled to vote at the SGB special meeting; (2) the receipt of all required regulatory approvals for the merger, without the imposition of any material on-going conditions or restrictions, and the expiration of all regulatory waiting periods; (3) the absence of any legal restraint (such as an injunction or restraining order) that would prevent the consummation of the merger; (4) the effectiveness of the registration statement of which this proxy statement/prospectus forms a part; (5) each party’s receipt of a tax opinion from its respective outside legal counsel, dated the closing date of the merger, confirming the merger qualifies as a “reorganization” within the meaning of Section 368(a) of the Code; (6) the Plan of Bank Merger in the form attached as Exhibit B to the merger agreement attached as Annex A to this document being executed and delivered; (7) the absence of the occurrence of a material adverse effect on SGB or First Bancshares; (8) SGB obtaining an actuarial analysis demonstrating that (i) SGB’s approximate total liability in respect of its pension plan on a termination basis will not materially exceed $13.8 million and (ii) the difference between such liability and the market value of the assets of the pension plan will not be expected to materially exceed $3.85 million, and (9) other customary closing conditions set forth in the merger agreement. See “The Merger Agreement — Conditions to Completion of the Merger” on page 74.

While it is currently anticipated that the merger will be completed during the second quarter of 2020, there can be no assurance that such conditions will be satisfied in a timely manner or at all, or that an effect, event, development or change will not transpire that could delay or prevent these conditions from being satisfied. Accordingly, there can be no guarantee with respect to the timing of the closing of the merger, whether the merger will be completed at all and when SGB shareholders will receive the merger consideration, if at all.

First Bancshares and SGB may waive one or more of the conditions to the merger without re-soliciting shareholder approval for the merger.

Each of the conditions to the obligations of First Bancshares and SGB to complete the merger may be waived, in whole or in part, to the extent permitted by applicable law, by agreement of First Bancshares and SGB, if the condition is a condition to both parties’ obligation to complete the merger, or by the party for which such condition is a condition of its obligation to complete the merger. The boards of directors of First Bancshares and SGB may evaluate the materiality of any such waiver to determine whether amendment of this proxy statement/prospectus and re-solicitation of proxies are necessary. First Bancshares and SGB, however, generally do not expect any such waiver to be significant enough to require re-solicitation of shareholders. In the event that any such waiver is not determined to be significant enough to require re-solicitation of shareholders, the companies will have the discretion to complete the merger without seeking further shareholder approval.

Regulatory approvals may not be received, may take longer than expected or impose conditions that are not presently anticipated.

Before the transactions contemplated by the merger agreement may be completed, approvals or waivers must be obtained from various regulatory authorities, which include the Federal Reserve Board, the OCC, and other securities and regulatory authorities. These governmental entities may request additional information or materials regarding the regulatory applications and notices submitted by First Bancshares and SGB, or may impose conditions on the granting of such approvals. Such conditions or changes and the process of obtaining regulatory approvals could have the effect of delaying the completion of the merger or of imposing additional costs or limitations on the combined company following the merger. The regulatory approvals may not be received at all, may not be received in a timely fashion, and may contain conditions on the completion of the merger that are not anticipated or cannot be met. There can be no assurance as to whether these and other regulatory approvals will be received, the timing of those approvals, or whether any conditions will be imposed. See “The Merger — Regulatory Approvals Required for the Merger” on page 56.

The directors and executive officers of SGB have interests in seeing the merger completed that are different from, or in addition to, those of the other SGB shareholders.

The directors and executive officers of SGB have arrangements that provide them with interests in the merger that are different from, or in addition to, those of the shareholders of SGB generally. These interests

TABLE OF CONTENTS

and arrangements may create potential conflicts of interest and may influence or may have influenced the directors and executive officers of SGB to support or approve the merger and the merger agreement. See “The Merger — Interests of SGB Directors and Executive Officers in the Merger” beginning on page 51.

The opinion of SGB’s financial advisor does not reflect changes in circumstances between the date of such opinion and the completion of the merger.

SGB’s board of directors received an opinion from its financial advisor to the effect that, as of December 18, 2019 and subject to the qualifications, assumptions and limitations set forth therein, the merger consideration was fair, from a financial point of view, to the holders of SGB common stock. Subsequent changes in the operations and prospects of SGB or First Bancshares, general market and economic conditions and other factors that may be beyond the control of SGB or First Bancshares, may significantly alter the value of SGB or First Bancshares or the price of the shares of First Bancshares common stock by the time the merger is completed. The opinion does not address the fairness of the merger consideration from a financial point of view at the time the merger is completed, or as of any other date other than the date of such opinion. The opinion of SGB’s financial advisor is attached as Annex B to this proxy statement/prospectus. For a description of the opinion, see “The Merger — Opinion of SGB’s Financial Advisor” on page 40.

The merger may be completed even if First Bancshares or SGB experiences adverse changes in its business.

In general, either First Bancshares or SGB may refuse to complete the merger if the other party suffers a material adverse effect on its business prior to the closing of the merger. However, certain types of changes or occurrences with respect to First Bancshares or SGB would not prevent the merger from going forward, even if the change or occurrence would have adverse effects on First Bancshares or SGB, including the following:

•

changes in laws and regulations affecting financial institutions and their holding companies generally, or interpretations thereof by courts or governmental entities, if such changes do not have a disproportionate impact on the affected company;

•

changes in GAAP or regulatory accounting requirements generally applicable to financial institutions and their holding companies, if such changes do not have a disproportionate impact on the affected company;

•

changes in global, national or regional political conditions including the outbreak of war or acts of terrorism, or in economic or market conditions affecting the financial services industry generally, if such changes do not have a disproportionate impact on the affected company;

•

changes or effects from the announcement of the merger agreement and the transactions contemplated thereby, and compliance by the parties with the merger agreement on the business, financial condition or results of operations of the parties;

•

any failure by SGB of First Bancshares to meet any internal or published industry analyst projections or forecasts or estimates of revenues or earnings for any period (but not including the underlying causes thereof);

•

changes in the trading price or trading volume of First Bancshares common stock (but not including the underlying causes thereof unless otherwise specifically excluded); however, SGB may terminate the merger agreement if (i) the average closing price of First Bancshares common stock during a specified period prior to closing is less than $26.86 and (ii) First Bancshares common stock underperforms the KBW Regional Banking Index by more than 20%, unless First Bancshares elects to make a compensating adjustment to the exchange ratio; and; and

•

the impact of the merger agreement and the transactions contemplated thereby on relationships with customers or employees, including the loss of personnel subsequent to the date of the merger agreement.

TABLE OF CONTENTS

Litigation in transactions of this type are sometimes filed against the board of directors of either party that could prevent or delay the completion of the merger or result in the payment of damages following completion of the merger.

In connection with the merger, it is possible that SGB shareholders may file putative class action lawsuits against the boards of directors of First Bancshares and/or SGB. Among other remedies, these shareholders could seek to enjoin the merger. The outcome of any such litigation would be uncertain. If a dismissal is not granted or a settlement is not reached, such potential lawsuits could prevent or delay completion of the merger and result in substantial costs to First Bancshares and SGB. The defense or settlement of any lawsuit or claim that remains unresolved at the time the merger is consummated may adversely affect the combined company’s business, financial condition, results of operations, cash flows and market price.

Risks Related to the Combined Company Following the Merger

The combined company expects to incur substantial expenses related to the merger.

The combined company expects to incur substantial expenses in connection with completing the merger and integrating the business and operations of SGB and First Bancshares. Although First Bancshares and SGB have assumed that a certain level of transaction and integration expenses would be incurred, there are a number of factors beyond their control that could affect the total amount or the timing of their integration expenses. Many of the expenses that will be incurred, by their nature, are difficult to estimate accurately at the present time. As a result, the transaction and integration expenses associated with the merger could, particularly in the near term, exceed the savings that the combined company expects to achieve from the integration of the businesses following the completion of the merger.

Following the merger, the combined company may be unable to integrate SGB’s business with First Bancshares successfully and realize the anticipated synergies and other benefits of the merger or do so within the anticipated timeframe.

The merger involves the combination of two companies that currently operate as independent companies, as well as the companies’ subsidiaries. Although the combined company is expected to benefit from certain synergies, including cost savings, the combined company may encounter potential difficulties in the integration process, including:

•

the inability to successfully combine SGB’s business with First Bancshares in a manner that permits the combined company to achieve the cost savings anticipated to result from the merger, which would result in the anticipated benefits of the merger not being realized in the timeframe currently anticipated or at all;

•

the risk of not realizing all of the anticipated operational efficiencies or other anticipated strategic and financial benefits of the merger within the expected timeframe or at all;

•

potential unknown liabilities and unforeseen increased expenses, delays or regulatory conditions associated with the merger; and

•

performance shortfalls as a result of the diversion of management’s attention caused by completing the merger and integrating the companies’ operations.

For all these reasons, you should be aware that it is possible that the integration process could result in the distraction of the combined company’s management, the disruption of the combined company’s ongoing business or inconsistencies in the combined company’s operations, any of which could adversely affect the ability of the combined company to maintain relationships with customers and employees or to achieve the anticipated benefits of the merger, or could otherwise adversely affect the business and financial results of the combined company.

Following the merger, the combined company may be unable to retain key employees.

The success of the combined company after the merger will depend in part upon its ability to retain key employees. Simultaneous with the execution of the merger agreement, First Bancshares entered into employment agreements with certain key employees of SGB, the effectiveness of which is conditioned upon

TABLE OF CONTENTS

the completion of the merger. However, key employees may depart either before or after the merger because of issues relating to the uncertainty and difficulty of integration or a desire not to remain with the combined company following the merger. Accordingly, no assurance can be given that SGB or First Bancshares or, following the merger, the combined company will be able to retain key employees.

The voting power of SGB shareholders will be diluted by the merger.

The merger will result in SGB shareholders having an ownership stake in the combined company that is smaller than their current stake in SGB. Upon completion of the merger of SGB with First Bancshares, we estimate that SGB shareholders will own approximately [ ]% of the issued and outstanding shares of common stock of the combined company. Consequently, SGB shareholders, as a general matter, will have less influence over the management and policies of the combined company after the effective time of the merger than they currently exercise over the management and policies of SGB.

Future capital needs could result in dilution of shareholder investment.

First Bancshares’ board of directors may determine from time to time there is a need to obtain additional capital through the issuance of additional shares of its common stock or other securities. These issuances would dilute the ownership interests of its shareholders and may dilute the per share book value of First Bancshares common stock. New investors may also have rights, preferences and privileges senior to First Bancshares’ shareholders which may adversely impact its shareholders.

Risks Related to an Investment in the Combined Company’s Common Stock

The market price of the shares of common stock of the combined company may be affected by factors different from those affecting the price of shares of First Bancshares common stock before the merger.

The results of operations of the combined company, as well as the market price of shares of the common stock of the combined company after the merger, may be affected by factors in addition to those currently affecting First Bancshares’ or SGB’s results of operations and the market prices of shares of First Bancshares common stock. Accordingly, the historical financial results of First Bancshares and SGB and the historical market prices of shares of First Bancshares common stock may not be indicative of these matters for the combined company after the merger. For a discussion of the businesses of First Bancshares and SGB and certain risks to consider in connection with evaluating the proposals to be considered at the SGB special meeting, see the documents incorporated by reference by First Bancshares into this proxy statement/prospectus referred to under “Where You Can Find More Information” beginning on page 95.

The market price of the combined company’s common stock may decline as a result of the merger.

The market price of the combined company’s common stock may decline as a result of the merger if the combined company does not achieve the perceived benefits of the merger or the effect of the merger on the combined company’s financial results is not consistent with the expectations of financial or industry analysts. In addition, upon completion of the merger, First Bancshares and SGB shareholders will own interests in a combined company operating an expanded business with a different mix of assets, risks and liabilities. Current First Bancshares and SGB shareholders may not wish to continue to invest in the combined company, or for other reasons may wish to dispose of some or all of their shares of the combined company.

After the merger is completed, SGB shareholders who receive shares of First Bancshares common stock in the merger will have different rights that may be less favorable than their current rights as SGB shareholders.

After the closing of the merger, SGB shareholders who receive shares of First Bancshares common stock in the merger will have different rights than they currently have as SGB shareholders, which may be less favorable than their current rights as SGB shareholders. For a detailed discussion of the significant differences between the current rights of a shareholder of SGB and the rights of a shareholder of the combined company following the merger, see “Comparison of Rights of First Bancshares shareholders and SGB Shareholders” beginning on page 83.

TABLE OF CONTENTS

THE SGB SPECIAL MEETING

This proxy statement/prospectus is being provided to the holders of SGB common stock as part of a solicitation of proxies by the SGB board of directors for use at the SGB special meeting to be held at the time and place specified below and at any properly convened meeting following an adjournment thereof. This proxy statement/prospectus provides the holders of SGB common stock with information they need to know to be able to vote or instruct their vote to be cast at the SGB special meeting.

General

SGB is furnishing this proxy statement/prospectus to the holders of SGB common stock as of the record date for use at SGB’s special meeting and any adjournment or postponement of its special meeting.

Date, Time and Place

The SGB special meeting will be held at Southwest Georgia Bank Administrative Services Building, located at 205 Second Street, S.E., Moultrie, Georgia 31768, on [ ] 2020, at [ ], Eastern Time, subject to any adjournment or postponement thereof.

Purpose of the SGB Special Meeting

At the SGB special meeting, SGB shareholders will be asked to consider and vote on the following:

•

Proposal One: The Merger Proposal — To approve the merger agreement, which we refer to as the merger proposal;

•

Proposal Two: The Compensation Proposal — To approve, on an advisory (non-binding) basis, the compensation that SGB’s named executive officers may receive in connection with the merger, which we refer to as the compensation proposal; and

•

Proposal Three: The Adjournment Proposal — To approve the adjournment of the SGB special meeting to a later date or dates, if the SGB board of directors determines it is necessary, among other things, to permit solicitation of additional proxies if there are not sufficient votes at the time of the SGB special meeting to approve the merger proposal.

Completion of the merger is conditioned on, among other things, the approval of the merger by the SGB shareholders.

No other matter can be brought up or voted upon at the SGB special meeting.

Proposals

Proposal One: Merger Proposal

SGB is asking its shareholders to approve the merger proposal. After careful consideration, SGB’s board of directors determined that the merger agreement and the transactions contemplated thereby, including the merger, were advisable and in the best interests of SGB and SGB’s shareholders.

SGB shareholders should carefully read this document in its entirety, including the annexes and the documents incorporated by reference, for more detailed information concerning the merger agreement and the merger. For a detailed discussion of the merger, including the terms and conditions of the merger agreement, see “The Merger Agreement,” beginning on page 61. In addition, SGB shareholders are directed to the merger agreement, a copy of which is attached as Annex A to this document and incorporated in this document by reference.

Proposal Two: Compensation Proposal

Pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and Rule 14a-21(c) under the Exchange Act, SGB is seeking non-binding, advisory approval from its shareholders of the compensation that SGB’s named executive officers may be entitled to receive from SGB that is based on or otherwise relates to the merger, as disclosed in table below and in further detail in “The

TABLE OF CONTENTS

Merger — Interests of SGB’s Directors and Executive Officers in the Merger.” The proposal gives SGB shareholders the opportunity to express their views on the merger-related compensation that SGB’s named executive officers may be entitled to receive from SGB.

The following table presents information about compensation payable by SGB to its named executive officers that is based on or otherwise relates to the merger, assuming the merger occurred on February 5, 2020. SGB’s two other named executive officers — Mr. John J. Cole, Jr. and Mr. Jeffery E. Hanson — resigned effective December 31, 2018 and September 30, 2019, respectively, and are not receiving any compensation from SGB that is based on or otherwise relates to the merger. Pursuant to Exchange Act Rule 14a-21(c), compensation payable by First Bancshares to Mr. Drew pursuant to his new employment agreement is not subject to the non-binding advisory vote on executive compensation, and therefore is not included in the table below.

Cash ($)(1)

Total ($)

DeWitt Drew

Reflects the lump sum payment that will be made to Mr. Drew by SGB at closing in connection with the termination of his employment agreement with SGB.

SGB is requesting its shareholders to adopt the following resolution, on a non-binding, advisory basis:

“RESOLVED, that the compensation that may be paid or become payable to SGB’s named executive officers in connection with the merger by SGB, and the agreements or understandings pursuant to which such compensation may be paid or become payable, in each case as disclosed pursuant to Item 402(t) of Regulation S-K in the table above and in “The Merger — Interests of SGB’s Directors and Executive Officers in the Merger” are hereby APPROVED.”

Approval of this proposal is not a condition to completion of the merger, and the vote with respect to this proposal is advisory only and will not be binding on First Bancshares or SGB. If the merger is completed, the merger-related compensation may be paid to SGB’s named executive officers to the extent payable in accordance with the terms of the compensation agreements and arrangements even if SGB’s shareholders fail to approve the advisory vote regarding merger-related compensation.

Proposal Three: Adjournment Proposal

If, at the SGB special meeting, the number of shares of SGB common stock present or represented and voting in favor of the merger proposal is insufficient to approve the merger proposal, SGB may move to adjourn the SGB special meeting in order to enable the SGB board of directors to solicit additional proxies for approval of the merger proposal. In that event, SGB’s shareholders will be asked to vote upon the adjournment proposal and not the merger proposal.

In the adjournment proposal, SGB is asking its shareholders to authorize the holder of any proxy solicited by its board of directors to vote in favor of granting discretionary authority to the SGB board of directors to adjourn the SGB special meeting to another time and place for the purpose of soliciting additional proxies. If SGB’s shareholders approve the adjournment proposal, SGB could adjourn the SGB special meeting and any adjourned session of the SGB special meeting and use the additional time to solicit additional proxies, including the solicitation of proxies from SGB shareholders who have previously voted. If a quorum is not present at the meeting, the meeting will not be convened to conduct business and neither the merger proposal nor the adjournment proposal will be considered. In the absence of a quorum, SGB may adjourn the meeting to a later date or time to solicit additional proxies.

Recommendation of the SGB Board of Directors

On December 18, 2019, the SGB board of directors unanimously determined that the merger agreement, the merger and the other transactions contemplated by the merger agreement are in the best interests of SGB and its shareholders, and it adopted the merger agreement and approved the merger and the other transactions contemplated by the merger agreement.

TABLE OF CONTENTS

Accordingly, the SGB board of directors unanimously recommends that SGB shareholders vote as follows:

•

“FOR” Proposal One approving the merger agreement;

•

“FOR” Proposal Two approving, on an advisory (non-binding) basis, the compensation that SGB’s named executive officers may receive in connection with the merger; and

•

“FOR” Proposal Three approving the adjournment of the SGB special meeting if necessary to permit solicitation of additional proxies.

Holders of SGB common stock should carefully read this proxy statement/prospectus, including any documents incorporated by reference, and the annexes in their entirety for more detailed information concerning the merger agreement, the merger and the other transactions contemplated by the merger agreement.

Record Date; Shareholders Entitled to Vote

The record date for the SGB special meeting is [ ], 2020, which we refer to herein as the SGB record date. Only record holders of shares of SGB common stock as of the close of business (5:00 p.m. Eastern Time), on the SGB record date are entitled to notice of, and to vote at, the SGB special meeting or any adjournment thereof. At the close of business on the SGB record date, the only outstanding securities of SGB with a right to vote on the proposals were SGB common stock, with [ ] shares of SGB common stock issued and outstanding. Each share of SGB common stock outstanding on the SGB record date is entitled to one vote on each proposal.

Quorum and Adjournment

No business may be transacted at the SGB special meeting unless a quorum is present. Holders representing at least a majority of the issued and outstanding shares of SGB common stock entitled to vote at the SGB special meeting must be present, in person or represented by proxy, to constitute a quorum.

Approval of the adjournment proposal requires the affirmative vote of a majority of the votes cast on the matter. If the adjournment of the SGB special meeting is for a period of less than 30 days, no notice of an adjourned SGB special meeting need be given if the new date, time and place are announced at the special meeting before adjournment, and no new record date is required to be set. If the meeting is adjourned to a date more than 120 days after the date fixed for the original meeting, a new record date must be set and a new notice must be given to the shareholders as of the new record date. At any adjourned SGB special meeting, all proxies will be voted in the same manner as they would have been voted at the original convening of the SGB special meeting, except for any proxies that have been effectively revoked or withdrawn prior to the adjourned SGB special meeting.

All shares of SGB common stock represented at the SGB special meeting, including shares that are represented but that vote to abstain, will be treated as present for purposes of determining the presence or absence of a quorum.

Vote Required for Approval; Abstentions; Failure to Vote

The required votes to approve the SGB proposals are as follows:

Proposal One: The Merger Proposal — Approving the merger proposal requires the affirmative vote of a majority of the issued and outstanding shares of SGB common stock entitled to vote at the SGB special meeting. Failure to vote and abstentions will have the same effect as a vote “AGAINST” this proposal.

Proposal Two: The Compensation Proposal — Approving the compensation proposal requires the affirmative vote of a majority of the votes cast on the matter. Failure to vote and abstentions will have no effect on this proposal.

Proposal Three: The Adjournment Proposal — Approving the adjournment proposal requires the affirmative vote of a majority of the votes cast on the matter. Failure to vote and abstentions will have no effect on this proposal.

If you sign your proxy but do not indicate your vote, your proxy will be voted “FOR” each proposal.

TABLE OF CONTENTS

Voting by SGB Directors and Executive Officers

At the close of business on the SGB record date, SGB directors and executive officers and their affiliates were entitled to vote [ ] shares of SGB common stock, or approximately [ ]% of the shares of SGB common stock outstanding on that date. SGB expects that its directors and executive officers and their affiliates will vote their shares in favor of all three SGB proposals.

SGB Common Stock Subject to Voting Agreements

All directors of SGB and Southwest Georgia Bank, solely in their capacity as shareholders of SGB, have entered into voting agreements with First Bancshares pursuant to which they have agreed to vote their shares of SGB common stock in favor of the approval of the merger agreement and the merger and against the approval or adoption of any proposal made in opposition to the merger. As of the SGB record date, [ ] shares of SGB common stock, or approximately [ ]% of the outstanding shares of SGB common stock entitled to vote at the SGB special meeting, are bound by the voting agreements.

Voting on Proxies by Holders of Record; Incomplete Proxies

If you were a record holder of SGB common stock at the close of business on the SGB record date, a proxy card is enclosed for your use. SGB requests that you vote your shares as promptly as possible by submitting your SGB proxy card by mail using the enclosed return envelope. If you are a registered shareholder, you may also vote via the Internet or telephone by following the instructions on the proxy card. When the accompanying proxy card is returned properly executed or if you voted via the Internet or telephone, the shares of SGB common stock represented by it will be voted at the SGB special meeting or any adjournment thereof in accordance with the instructions contained in the proxy card.

If a record holder returns an executed proxy card without an indication as to how the shares of SGB common stock represented by it are to be voted with regard to a particular proposal, the shares of SGB common stock represented by the proxy will be voted in accordance with the recommendation of the SGB board of directors and, therefore, such shares will be voted:

•

“FOR” Proposal One approving the merger agreement;

•

“FOR” Proposal Two approving, on an advisory (non-binding) basis, the compensation that SGB’s named executive officers may receive in connection with the merger; and

•

“FOR” Proposal Three approving the adjournment of the SGB special meeting, if necessary to permit solicitation of additional proxies.

At the date hereof, the SGB board of directors has no knowledge of any business that will be presented for consideration at the SGB special meeting and that would be required to be set forth in this proxy statement/prospectus or the related proxy card other than the matters set forth in SGB’s Notice of Special Meeting of Shareholders.

Your vote is important. Accordingly, if you were a record holder of SGB common stock on the SGB record date, please sign, date and return the enclosed proxy card or vote via the Internet or telephone whether or not you plan to attend the SGB special meeting in person.

If your shares of SGB common stock are held in an account with a bank, broker or other nominee, which are referred to as shares held in “street name,” the bank, broker or other nominee is considered the shareholder of record with respect to these shares and you are the beneficial owner of these “street name” shares. If your shares are held in “street name” through a broker, bank or other nominee, you will receive instructions from your broker, bank or other nominee that you must follow in order to vote your shares. You should refer to the voting form used by that firm to determine whether you may vote by telephone, Internet or mail.

If your shares are held in “street name,” SGB recommends that you mark, date, sign and promptly mail the voting instruction form provided by your bank, broker or other nominee in accordance with the instructions provided by such nominee.

TABLE OF CONTENTS

Banks, brokers and other nominees who hold shares of SGB common stock in “street name” for a beneficial owner of those shares typically have the authority to vote in their discretion on “routine” proposals when they have not received instructions from beneficial owners. However, banks, brokers and other nominees are not allowed to exercise their voting discretion with respect to the approval of matters determined to be “non-routine,” without specific instructions from the beneficial owner. The merger proposal, the compensation proposal and the adjournment proposal are non-routine matters. Accordingly, if your broker, bank or other nominee holds your shares of SGB common stock in “street name,” your broker, bank or other nominee will vote your shares of SGB common stock with respect to the merger proposal, the compensation proposal and the adjournment proposal only if you provide instructions on how to vote by filling out the voter instruction form sent to you by your broker, bank or other nominee with this proxy statement/prospectus. If you do not provide instructions to your broker, bank or other nominee with respect to either the merger proposal, the compensation proposal or the adjournment proposal, it will result in a failure to vote your shares on such proposal. Failure to vote has the same effect as a vote against the merger proposal.

Revocability of Proxies and Changes to an SGB Shareholder’s Vote

An SGB shareholder entitled to vote at the SGB special meeting may revoke a proxy at any time before such time that the proxy card for any such holders of SGB common stock must be received at the SGB special meeting by taking any of the following actions:

•

delivering written notice of revocation to Secretary of the Corporation at Southwest Georgia Financial Corporation, P.O. Box 3488, Moultrie, Georgia 31776-3488;

•

delivering a proxy card bearing a later date than the proxy that such shareholder desires to revoke;

•

voting by telephone or on the Internet (your latest telephone or Internet vote will be counted); or

•

attending the SGB special meeting and voting in person.

Merely attending the SGB special meeting will not, by itself, revoke your proxy; an SGB shareholder must cast a subsequent vote at the SGB special meeting using forms provided for that purpose. The last valid vote that SGB receives before the polls close at the SGB special meeting is the vote that will be counted.

If you hold your shares in “street name” through a bank, broker or other nominee (referred to in this proxy statement/prospectus as a “beneficial owner”), you must contact such bank, broker or nominee if you desire to revoke your proxy as described above.

Solicitation of Proxies

The SGB board of directors is soliciting proxies for the SGB special meeting from holders of its SGB common stock entitled to vote at the SGB special meeting. In accordance with the merger agreement, SGB will pay its own cost of soliciting proxies from its shareholders, including the cost of mailing this proxy statement/prospectus. In addition to solicitation of proxies by mail, proxies may be solicited by SGB’s officers, directors and regular employees, without additional remuneration, in person, by telephone or other means of communication.

SGB or its proxy solicitor will make arrangements with brokerage houses, custodians, nominees and fiduciaries to forward proxy solicitation materials to beneficial owners of SGB common stock. SGB may reimburse these brokerage houses, custodians, nominees and fiduciaries for their reasonable expenses incurred in forwarding the proxy materials.

SGB has also made arrangements with Alliance Advisors to assist it in soliciting proxies and has agreed to pay Alliance Advisors approximately $6,000 plus reasonable expenses for these services.

Attending the SGB Special Meeting; Voting in Person

Only record holders of SGB common stock at the close of business on the record date, their duly appointed proxies, and invited guests may attend the SGB special meeting. However, only holders of SGB common stock will be entitled to vote.

TABLE OF CONTENTS

A shareholder who holds shares in “street name” through a broker, bank, trustee or other nominee who desires to attend the SGB special meeting in person must bring proof of beneficial ownership as of the record date, such as a letter from the broker, bank, trustee or other nominee that is the record owner of such beneficial owner’s shares, a brokerage account statement or the voting instruction form provided by the broker.

A person who holds a validly executed proxy entitling such person to vote on behalf of a record owner of SGB common stock who desires to attend the SGB special meeting in person must also bring the validly executed proxy naming such person as the proxy holder, signed by the SGB shareholder of record, and proof of the signing shareholder’s record ownership as of the record date.

Delivery of Proxy Materials to Shareholders Sharing an Address

As permitted by the Exchange Act, only one copy of this proxy statement/prospectus is being delivered to multiple shareholders of SGB sharing an address unless SGB has previously received contrary instructions from one or more such shareholders. This is referred to as “householding.” Shareholders who hold their shares in “street name” can request further information on householding through their banks, brokers, or other holders of record. On written or oral request to Alliance Advisors at 200 Broadacres Drive, 3rd Floor, Bloomfield, NJ 07003 or toll-free at (800) 574-6108, SGB will deliver promptly a separate copy of this document to a shareholder at a shared address to which a single copy of the document was delivered.

Assistance

If you need assistance in completing your proxy card, have questions regarding the SGB special meeting or would like additional copies of this proxy statement/prospectus, please contact Steve Johnson, Vice President and Secretary at (229) 985-1120 or SGB’s proxy solicitor, Alliance Advisors at 200 Broadacres Drive, 3rd Floor, Bloomfield, NJ 07003 or toll-free at (800) 574-6108.

TABLE OF CONTENTS

THE MERGER

The following discussion contains certain information about the merger. The discussion is subject, and qualified in its entirety by reference, to the merger agreement attached as Annex A to this proxy statement/prospectus. We urge you to read carefully this entire proxy statement/prospectus, including the merger agreement attached as Annex A, for a more complete understanding of the merger.

General

Each of First Bancshares’ and SGB’s respective boards of directors has unanimously approved the merger agreement and the transactions contemplated by the merger agreement. The merger agreement provides for the acquisition of SGB by First Bancshares pursuant to the merger of SGB with and into First Bancshares, with First Bancshares as the surviving company, which we refer to as the merger. Immediately after the merger, Southwest Georgia Bank, a wholly owned bank subsidiary of SGB, will be merged with and into The First, a wholly owned bank subsidiary of First Bancshares, with The First as the surviving bank, which we refer to as the bank merger.

Purchase Price and Purchase Price Adjustments

At the effective time of the merger, each share of SGB common stock issued and outstanding immediately prior to the effective time of the merger will be converted into the right to receive 1.00, or the exchange ratio, share of First Bancshares common stock. To the extent that any shares of SGB common stock are subject to vesting restrictions, the same terms and conditions currently applicable to such shares of SGB common stock will continue to apply to the converted shares First Bancshares common stock received in connection with the merger, with certain exceptions where the holder of the shares of restricted stock is terminated as an employee of First Bancshares within one year of the completion of the merger (other than for cause, death, disability, normal retirement or voluntary resignation).

Before deciding how to vote, you should obtain more recent prices of First Bancshares common stock, which trades on the NASDAQ Global Market under the symbol “FBMS”.

The exchange ratio was arrived at through arm’s-length negotiations between SGB and First Bancshares. The merger agreement provides that if First Bancshares effects a stock dividend, reclassification, recapitalization, split, or combination of the shares of First Bancshares common stock, then an appropriate adjustment to the exchange ratio will be made.

SGB shareholders are being asked to approve the merger agreement. See “The Merger Agreement” for additional and more detailed information regarding the legal documents that govern the merger, including information about the conditions to the completion of the merger and the provisions for terminating or amending the merger agreement.

Background of the Merger

SGB and Southwest Georgia Bank’s boards of directors have considered and regularly reviewed SGB’s strategic direction, business objectives and long-term prospects, as well as challenges that may affect SGB’s ability to grow or maintain its business and maximize shareholder value, as part of their continuous efforts to enhance value for shareholders and other constituencies. These considerations have focused on, among other things, growth opportunities, prospects and developments in the regulatory environment, conditions and ongoing consolidation in the financial services industry, and the economy generally and financial markets, both with respect to financial institutions generally and SGB in particular.

TABLE OF CONTENTS

In June 2018, the board of directors of SGB considered options that SGB might pursue in order to maximize opportunities for the business and value for SGB’s shareholders including strategic alternatives, such as merging SGB with a larger financial institution. Jeff Adams of BSP met with DeWitt Drew, President and Chief Executive Officer of SGB, in late July 2018 to provide an update of SGB’s franchise value and a review of SGB’s most likely acquirers, one of which was First Bancshares. Such valuation updates were part of a multi-year relationship that had been built between BSP and SGB.

In July 2018, BSP approached First Bancshares to gauge its interest in meeting with representatives of SGB management to learn more about SGB and Southwest Georgia Bank as a potential strategic partner.

In September 2018, Mr. Drew in consultation with the joint board of directors of SGB and Southwest Georgia, met with M. Ray (Hoppy) Cole, Jr., President and Chief Executive Officer of First Bancshares’ to discuss First Bancshares’ potential interest in acquiring SGB. At this meeting, the parties discussed the potential strategic fit of the two companies and certain high-level diligence considerations.

In October 2018, representatives of SGB and First Bancshares management met again to discuss a potential combination at a high level and the complimentary aspects of each company.

In January 2019, SGB officially engaged BSP to serve as its financial advisor and to provide the joint board of directors of SGB and Southwest Georgia Bank with input and advice regarding its strategic partnership options including a potential strategic combination with First Bancshares and another third party.

On February 6, 2019, representatives of management of SGB and representatives of management First Bancshares met for a third time to continue discussions regarding a potential combination.

On March 13, 2019, at a regularly held meeting of the joint board of directors of SGB and Southwest Georgia Bank, representatives from BSP and Troutman Sanders LLP, SGB’s legal counsel, each presented to the board on matters related SGB’s contemplation of strategic alternatives. Specifically, a representative of BSP presented to the joint board of directors a broad review of the current operating environment for banks, observations regarding SGB, preliminary valuation analyses and potential acquisition partners, including First Bancshares. In addition, a representative of Troutman discussed SGB board of directors’ fiduciary duties in connection with its evaluation of strategic alternatives.

In April 2019, First Bancshares continued to express interest in acquiring SGB and, on April 29, 2019, executed a mutual nondisclosure agreement with SGB with respect to the parties’ discussions of a potential merger and due diligence.

On May 10, 2019, BSP distributed a Confidential Information Memorandum (“CIM”) relating to SGB and its business to First Bancshares.

On May 28, 2019, SGB received an unsolicited inquiry from a representative of another financial institution (“Company A”) expressing interest in a possible transaction with SGB. SGB then proceeded to enter into a mutual nondisclosure agreement with Company A on May 30, 2019 and provided Company A with the CIM relating to SGB.

On June 10, 2019, Company A verbally expressed interest to BSP in acquiring SGB, noting, however, that a competitive proposal would be difficult to make given the market conditions at that time.

On June 21, 2019, First Bancshares submitted a preliminary non-binding indication of interest with initial pricing terms to gauge SGB’s interest in continuing discussions of a potential merger. At a special meeting of the joint board of directors of SGB and Southwest Georgia Bank, the joint board determined First Bancshares initial proposal was too low and decided to discontinue formal discussions with First Bancshares with respect to a potential combination.

In August 2019, a third financial institution (“Company B”) expressed interest in a strategic combination with SGB. After speaking with representatives of SGB management and representatives of BSP, Company B submitted a non-binding indication of interest on August 26, 2019.

On August 23, 2019, Company A informed representatives of SGB and BSP that it would not be submitting a formal non-binding indication of interest, because it was pursuing other strategic matters. Also in August 2019, First Bancshares notified SGB that it would be discussing whether it would submit a revised non-binding indication of interest with a higher valuation of SGB at its board meeting on September 10, 2019.

TABLE OF CONTENTS

In September 2019, SGB instructed BSP to inform both First Bancshares and Company B to improve their respective initial proposals to continue to be considered as a potential strategic partner of SGB. On September 10, 2019, Company B’s Chief Executive Officer submitted and presented its revised non-binding indication of interest to the joint board of directors of SGB and Southwest Georgia in Moultrie, GA. On September 11, 2019 First Bancshares submitted its revised non-bonding indication of interest. On September 18, 2019, at a special meeting of the joint board of directors of SGB and Southwest Georgia Bank, BSP presented the two revised proposals to the joint board of directors. After discussion and questions to BSP, the board decided to proceed with full due diligence with both First Bancshares and Company B. With the assistance of BSP, SGB responded to each party’s respective diligence request list.

First Bancshares and Company B were asked to provide final proposals by November 14, 2019. On November 13, 2019, First Bancshares presented its final non-binding indication of interest to the joint board of directors of SGB and Southwest Georgia Bank. Representatives of BSP also attended the meeting. On November 14, 2019, Company B submitted its final non-binding indication of interest.

On November 18, 2019, at a special meeting of the joint board of directors of SGB and Southwest Georgia Bank, BSP presented the two final non-binding indications of interest to the joint board of directors. A representative from Troutman also attended the meeting. Thereafter, on November 19, 2019, First Bancshares revised its final proposal to increase the offered exchange ratio range from 0.9885 to 1.00 and to include a non-binding intent to achieve dividend parity with SGB. After discussing First Bancshares revised proposal and Company’s B’s final proposal, the joint board of directors of SGB and Southwest Georgia Bank, decided to negotiate exclusively with First Bancshares and complete its reverse due diligence with respect to First Bancshares. SGB executed a letter of intent with First Bancshares on November 21, 2019.

Over the course of the remainder of November 2019 and during the first two weeks of December 2019, SGB continued to make additional due diligence materials available to First Bancshares and its representatives, and SGB’s management and its representatives participated in due diligence discussions with First Bancshares and its representatives.

On November 25, 2019, First Bancshares legal counsel, Alston & Bird LLP (“Alston & Bird”), circulated an initial draft of the merger agreement and ancillary documents, including forms of a voting agreement, a non-competition and non-disclosure agreement and a claims letter to be entered into by SGB’s and Southwest Georgia Bank’s directors. For the first two weeks of December 2019, the parties, with the assistance of legal counsel and financial advisors, negotiated the merger agreement and ancillary documents.

On December 16, 2019, a regular meeting of the joint board of directors of SGB and Southwest Georgia Bank was held and was attended by representatives of Troutman and BSP. At the meeting, and the transaction was considered generally and representatives of Troutman reviewed the final terms of the proposed transaction documents, including the merger agreement, with the joint board and discussed the board’s fiduciary duties in connection with SGB and Southwest Georgia Bank’s potential transaction with First Bancshares and The First.

On December 18, 2019, a special meeting of the joint board of directors of SGB and Southwest Georgia Bank was held, which was attended by representatives of Troutman and BSP. Representatives of BSP presented BSP’s financial analyses with respect to the per share merger consideration to be paid to the holders of SGB common stock pursuant to First Bancshares’ proposal. Representatives of BSP then rendered an oral opinion to the joint board of directors of SGB and Southwest Georgia Bank, which was confirmed by delivery of a written opinion, dated December 18, 2019, to the effect that, as of such date and based upon and subject to the factors, assumptions and limitations set forth in its opinion, the merger consideration to be paid pursuant to the merger agreement was fair, from a financial point of view, to the holders of SGB common stock.

After careful consideration and discussion, and taking into consideration the matters discussed during the December 18, 2019 meeting and prior meetings of the joint board of directors of SGB and Southwest Georgia Bank, including the factors described under “— SGB’s Reasons for the Merger; Recommendation of the SGB Board of Directors,” the joint board of directors of SGB and Southwest Georgia Bank

TABLE OF CONTENTS

unanimously approved the merger agreement and the transactions contemplated by the merger agreement, determined that the merger, on the terms and conditions set forth in the merger agreement, is in the best interests of SGB and Southwest Georgia Bank and directed that the merger agreement and the transactions contemplated thereby be submitted to SGB’s shareholders for approval at a meeting of such shareholders.

On the afternoon of December 18, 2019, the merger agreement and the voting agreements, non-competition and non-disclosure agreements and claims letters were executed and delivered by the parties thereto, and SGB and First Bancshares publicly announced their entry into the merger agreement via a joint press release.

First Bancshares’ Reasons for the Merger

In reaching its decision to approve and adopt the merger agreement, the merger and the other transactions contemplated by the merger agreement, including the issuance of First Bancshares common stock as the merger consideration, the First Bancshares board of directors considered a number of factors, including the following material factors:

Opinion of SGB’s Financial Advisor

BSP was retained by SGB’s board of directors on an exclusive basis to render financial advisory and investment banking services and to render a written opinion to the board of directors of SGB as to the fairness, from a financial point of view, of the merger consideration to be paid under the terms of the

TABLE OF CONTENTS

merger agreement. BSP is an investment banking firm that specializes in providing financial advisory and investment banking services to financial institutions. BSP has been involved in many bank-related business combinations. No limitations were imposed by SGB upon BSP with respect to rendering its opinion.

The full text of BSP’s written opinion, dated December 18, 2019, is attached as Annex B to this proxy statement/prospectus and is incorporated herein by reference. The description of the opinion set forth herein is qualified in its entirety by reference to the full text of such opinion. SGB’s stockholders are urged to read the opinion in its entirety.

The opinion speaks only as of the date of the opinion. The opinion was directed to SGB’s board of directors and is directed only to the fairness, from a financial point of view, of the merger consideration to be paid. It does not address the underlying business decision to engage in the merger or any other aspect of the merger and is not a recommendation to any shareholder as to how such shareholder should vote with respect to the merger or any other matter.

For purposes of this opinion and in connection with our review of the proposed merger, BSP has, among other things:

In connection with its review, BSP has not independently verified any of the foregoing information and BSP has assumed and relied upon such information being complete and accurate in all material respects. With respect to the financial forecasts for SGB that BSP used in its analyses, the management of SGB has advised BSP, and it has assumed, that such forecasts have been reasonably prepared on bases reflecting the best currently available estimates and judgments of the management of SGB as to the future financial performance of SGB and BSP expresses no opinion with respect to such estimates or the assumptions on which they are based. BSP has relied upon and assumed, without independent verification, that there has been no change in the business, assets, liabilities, financial condition, results of operations, cash flows or prospects of SGB and First Bancshares since the respective dates of the most recent financial statements and other information, financial or otherwise, provided to BSP that would be material to its analyses or its opinion, and that there is no information or any facts that would make any of the information reviewed by BSP incomplete or misleading. BSP has also assumed, with SGB’s consent, that, in the course of obtaining any regulatory or third party consents, approvals or agreements in connection with the merger, no delay, limitation, restriction or condition will be imposed that would have an adverse effect on SGB, First Bancshares or the contemplated benefits of the merger and that the merger will be consummated in

TABLE OF CONTENTS

accordance with the terms of the merger agreement without waiver, modification or amendment of any term, condition or provision thereof that would be material to BSP’s analyses or its opinion. BSP has assumed, with SGB’s consent, that the merger agreement, when executed by the parties thereto, conformed to the draft reviewed by BSP in all respects material to its analyses.

BSP’s opinion only addresses the fairness, from a financial point of view, of the merger consideration to the holders of SGB common stock in the manner set forth in the full text of its opinion, which is included as Annex B, and the opinion does not address any other aspect or implication of the merger or any agreement, arrangement or understanding entered into in connection with the merger or otherwise, including, without limitation, the amount or nature of, or any other aspect relating to, any compensation to any officers, trustees, directors or employees of any party to the merger, or class of such persons, relative to the merger consideration or otherwise.

The issuance of BSP’s opinion was approved by an authorized internal committee of BSP.

BSP’s opinion was necessarily based upon information made available to it as of the date the opinion was delivered of December 18, 2019, and financial, economic, market and other conditions as they existed and could be evaluated on the date the opinion was delivered. BSP has no obligation to update, revise, reaffirm or withdraw its opinion, or otherwise comment on or consider events occurring after the date the opinion was delivered. BSP’s opinion does not address the relative merits of the merger as compared to alternative transactions or strategies that might be available to SGB, nor does it address the underlying business decision of SGB or the Board to approve, recommend or proceed with the merger. Furthermore, no opinion, counsel or interpretation is intended in matters that require legal, regulatory, accounting, insurance, tax or other similar professional advice. It is assumed that such opinions, counsel or interpretations have been or will be obtained from the appropriate professional sources. Furthermore, BSP has relied on, with SGB’s consent, advice of the outside counsel and the independent accountants of SGB, and on the assumptions of the management of SGB, as to all legal, regulatory, accounting, insurance and tax matters with respect to SGB, First Bancshares, and the merger.

Based upon and subject to the foregoing and based on BSP’s experience as investment bankers, BSP’s activities as described above, and other factors deemed relevant, BSP rendered its opinion that, as of December 18, 2019, the merger consideration to be paid is fair to the holders of SGB common stock, from a financial point of view.

The following is a summary of material analyses performed by BSP in connection with its opinion to the SGB board of directors on December 18, 2019. The summary does not purport to be a complete description of the analyses performed by BSP but summarizes the material analyses performed and presented in connection with such opinion.

Financial Analysis

In rendering its opinion, BSP performed a variety of financial analyses. The summary below is not a complete description of all the analyses underlying BSP’s opinion or the presentation made by BSP to the SGB board of directors, but is a summary of the material analyses performed and presented by BSP. The summary includes information presented in tabular format. In order to fully understand the financial analyses, these tables must be read together with the accompanying text. The tables alone do not constitute a complete description of the financial analyses. The preparation of a fairness opinion is a complex process involving subjective judgments as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances. The process, therefore, is not necessarily susceptible to a partial analysis or summary description. BSP believes that its analysis must be considered as a whole and that selecting portions of the factors and analyses to be considered without considering all factors and analyses, or attempting to ascribe relative weights to some or all such factors and analyses, could create an incomplete view of the evaluation process underlying its opinion. Also, no company included in the comparative analyses described below is identical to SGB or First Bancshares and no transaction is identical to the merger. Accordingly, an analysis of comparable companies or transactions involves complex considerations and judgments concerning differences in financial and operating characteristics of the companies and other factors that could affect the public trading values or merger transaction values, as the case may be, of SGB and First Bancshares and the companies to which they are being compared.

TABLE OF CONTENTS

In arriving at its opinion, BSP did not attribute any particular weight to any analysis or factor that it considered. Rather, BSP made qualitative judgments as to the significance and relevance of each analysis and factor. BSP did not form an opinion as to whether any individual analysis or factor (positive or negative) considered in isolation supported or failed to support its opinion; rather, BSP made its determination as to the fairness of the merger consideration on the basis of its experience and professional judgment after considering the results of all of the analyses taken as a whole.

In performing its analysis, BSP also made numerous assumptions with respect to industry performance, business and economic conditions and various other matters, many of which are beyond the control of SGB, First Bancshares and BSP. The analyses performed by BSP are not necessarily indicative of actual values or future results, both of which may be significantly more or less favorable than suggested by such analyses. BSP prepared its analyses solely for purposes of rendering its opinion and presented such analyses to the SGB board of directors at its December 18, 2019 meeting. Estimates of the values of companies do not purport to be appraisals or necessarily reflect the prices at which companies or their securities may actually be sold. Such estimates are inherently subject to uncertainty, and actual values may be materially different. Accordingly, BSP’s analysis does not necessarily reflect the value of SGB’s or First Bancshares’ common stock or the prices at which SGB’s common stock or First Bancshares’ common stock may be sold at any time. BSP’s analysis was among a number of factors taken into consideration by SGB’s board of directors in making its determination to approve the merger agreement and should not be viewed as determinative of the merger consideration or the decision of SGB’s board of directors or management with respect to the fairness of the merger.

Precedent Transactions Analysis

BSP reviewed two sets of comparable merger and acquisition transaction. The sets of mergers and acquisitions included: (1) Southeast Transactions and (2) U.S. Transactions.

“Southeast Transactions” included 12 transactions where:

•

The transaction was announced on or after January 1, 2019; and

•

The transaction involved selling banks and thrifts headquartered in the Southeast; and

•

The target’s assets were between $200.0 million and $1.0 billion; and

•

The target’s LTM ROAA were greater than 0.50%.

“U.S. Transactions” included 20 transactions where:

•

The transaction was announced on or after January 1, 2019; and

•

The transaction involved selling banks and thrifts headquartered in the U.S.; and

•

The target’s total assets were between $350.0 million and $750.0 million as of announcement; and

•

The target’s LTM ROAA were greater than 0.50% as of announcement.

The following tables set forth the transactions included in (1) Southeast Transactions and (2) U.S. Transactions. Using the latest publicly available information prior to the announcement of the relevant transaction, BSP reviewed the transaction metrics for the precedent transaction groups: transaction price to last-twelve-months earnings, transaction price to tangible book value, transaction price to total assets and tangible book premium to core deposits. BSP calculated an implied value of the merger $87.9 million, based on the closing price of First Bancshares common stock on December 17, 2019, and used such implied value to calculate transaction multiples for the merger. BSP compared the indicated transaction multiples for the merger to the median multiples of the precedent transaction groups. Transactions involving investors, investor groups and troubled bank sellers were excluded from the precedent transaction analysis.

Relative Contribution Analysis

BSP reviewed the relative contributions of SGB and First Bancshares to the pro forma combined company with respect to certain financial and operating measurements. This analysis was based on projected March 31, 2020 financials for both parties. BSP then compared these contributions to the pro forma implied stock ownership interests of SGB and First Bancshares shareholders based on the merger agreement’s exchange ratio.

The following table shows SGB’s percentage contributions to the pro forma combined company, excluding merger synergies and merger accounting adjustments, in the categories listed:

	Southwest Georgia Contribution
Total Assets		12.4%
Total Loans		13.0%
Total Deposits		13.0%
Tangible Common Equity		12.5%

2019 Estimated Net Income		11.4%
2020 Estimated Net Income		11.7%
SGB Pro Forma Ownership		11.9%

Merger Premium Analysis

BSP reviewed the one-day announcement merger premium of certain U.S. transactions announced since in January 1, 2019. The list of 36 transactions included all transactions announced with selling banks and thrifts with total assets greater than $1.0 billion and with common stock listed on the NASDAQ and over-the-counter exchanges at the time of announcement.

Net Present Value Analysis of SGB

BSP also performed an analysis that estimated the net present value per share of SGB common stock on a standalone basis assuming SGB performed in accordance with management guidance for 2020 – 2022. For purposes of this analysis, it was assumed that SGB would earn $2.95 per share in 2020, $3.27 per share in 2021, and $3.61 per share in 2022. To approximate the terminal trading value of a share of SGB common stock at December 31, 2022, BSP applied price to 2022 earnings per share multiples ranging from 10.0x to

TABLE OF CONTENTS

13.0x and price to December 31, 2022 tangible book value per share multiples ranging from 100% to 130%. The terminal values were then discounted to present values using different discount rates ranging from 13.0% to 17.0%, which were chosen to reflect different assumptions regarding required rates of return of holders or prospective buyers of SGB common stock. As illustrated in the following tables, the analysis indicated an imputed range of values per share of SGB common stock of $24.21 to $34.27 when applying multiples of earnings per share and $18.96 to $26.70 when applying multiples of tangible book value per share.

Net Present Value Analysis of First Bancshares

BSP performed an analysis that estimated the net present value per share of First Bancshares common stock on a standalone basis assuming First Bancshares performed in accordance with mean analyst operating income estimates for 2020 and 2021 and BSP projections for 2022. For purposes of this analysis, BSP assumed that First Bancshares would earn $3.01 per share in 2020, $3.15 per share in 2021 and $3.31 per share in 2022. To approximate the terminal trading value of a share of First Bancshares common stock at December 31, 2022, BSP applied price to 2022 earnings per share multiples ranging from 13.0x to 16.0x and price to December 31, 2022 tangible book value per share multiples ranging from 150% to 180%. The terminal values were then discounted to present values using different discount rates ranging from 10.0% to 14.0%, which were chosen to reflect different assumptions regarding required rates of return of holders or prospective buyers of First Bancshares common stock. As illustrated in the following tables, the analysis indicated an imputed range of values per share of First Bancshares common stock of $30.09 to $40.90 when applying multiples of earnings per share and $28.75 to $38.11 when applying multiples of tangible book value per share.

Net Present Value Analysis of Pro Forma First Bancshares

BSP performed an analysis that estimated the net present value per share of First Bancshares common stock on a pro forma basis. For purposes of this analysis, BSP prepared projections for the pro forma combined company based on (i) mean analyst estimates for First Bancshares on a standalone basis for 2020 and 2021, (ii) BSP’s projections for First Bancshares on a standalone basis for 2022, (iii) SGB management guidance for SGB on a standalone basis for 2020-2022, and (iv) BSP estimated impact of cost savings and other merger-related adjustments for 2020 through 2022. For purposes of this analysis, BSP assumed that the pro forma combined company would earn $3.07 per share in 2020, $3.31 per share in 2021 and $3.50 per share in 2022. To approximate the terminal trading value of a share of the pro forma combined company, at December 31, 2022, BSP applied price to 2022 earnings per share multiples ranging from 13.0x to 16.0x and price to December 31, 2022 tangible book value per share multiples ranging from 150% to 180%. The terminal values were then discounted to present values using different discount rates ranging from 10.0% to 14.0%, which were chosen to reflect different assumptions regarding required rates of return of holders or prospective buyers of First Bancshares common stock. As illustrated in the following tables, the analysis indicated an imputed range of values per share of First Bancshares common stock of $30.92 to $42.30 when applying multiples of earnings per share and $28.13 to $37.51 when applying multiples of tangible book value per share.

Conclusion

Based on the results of the various analyses described above, BSP concluded that the merger consideration to be paid under the terms of the merger agreement was fair, from a financial point of view, to the holders of SGB common stock.

The opinion expressed by BSP was based upon market, economic and other relevant considerations as they existed and could be evaluated as of the date of the opinion. Events occurring after the date of issuance of the opinion, including, but not limited to, changes affecting the securities markets, the results of operations or material changes in the assets or liabilities of SGB or First Bancshares, could materially affect the assumptions used in preparing the opinion.

TABLE OF CONTENTS

As described above, BSP’s opinion was among the many factors taken into consideration by the SGB board of directors in making its determination to approve the merger agreement. For purposes of rendering its opinion, BSP assumed that:

•

the representations and warranties of all parties to the merger agreement and all other related documents and instruments that are referred to therein are true and correct,

•

each party to all such agreements will perform all of the covenants and agreements required to be performed by such party,

•

all conditions to the consummation of the merger will be satisfied without waiver thereof, and

•

the merger will be consummated in a timely manner in accordance with the terms described in the merger agreement, without any amendments or modifications thereto or any adjustments to the consideration.

BSP cannot provide assurance as to when or if all of the conditions to the merger can or will be satisfied or, if applicable, waived by the appropriate party.

Compensation to BSP

BSP was engaged as financial advisor to SGB in connection with the merger. Pursuant to the terms of the engagement agreement, SGB agreed to pay BSP certain fees in conjunction with this transaction, $20,000 of which was paid upon signing of the engagement letter, $75,000 of which was paid upon the signing of a merger agreement (the “Progress Fee”) and $25,000 which was paid upon BSP’s delivery of the written opinion to SGB. Upon closing of the transaction, BSP will be paid a fee calculated as 1.00% of total consideration (the “Success Fee”), which is currently estimated to be $[ ]. The Progress Fee will be credited toward the Success Fee. In addition, SGB has agreed to indemnify BSP and its directors, officers and employees from liability in connection with the transaction, and to hold BSP harmless from any losses, actions, claims, damages, expenses or liabilities related to any of BSP’s acts or decisions made in good faith and in the best interest of SGB. During the two years preceding the current engagement associated with the merger, BSP did not provide advisory services to SGB and/or its affiliates where compensation was received. During the two years preceding SGB’s current engagement of BSP associated with the merger, BSP’s affiliate, Performance Trust Capital Partners, LLC, has provided certain investment banking services and received a success fee of $405,000 from First Bancshares in connection with a transaction which closed in April 2018 and a retainer of $25,000 from First Bancshares for a transaction that was never completed in June 2018.

Board Composition and Management of First Bancshares after the Merger

Each of the officers and directors of First Bancshares immediately prior to the effective time of the merger will be the officers and directors of the surviving company from and after the effective time of the merger, until their respective successors have been duly elected, appointed or qualified or until their earlier death, resignation or removal in accordance with the First Bancshares Articles and First Bancshares Bylaws.

Interests of SGB Directors and Executive Officers in the Merger

In considering the recommendations of the SGB board of directors that SGB shareholders vote in favor of the merger proposal, you should be aware that SGB’s directors and executive officers may have interests in the merger that differ from, or are in addition to, their interests as shareholders of SGB. The SGB board of directors was aware of these interests and took them into account in its decision to approve the merger agreement.

Treatment of SGB Equity Awards

At the Effective Time, each share of SGB common stock issued and outstanding immediately prior to the effective time of the merger will be converted into the right to receive 1.00, or the exchange ratio, share of First Bancshares common stock. To the extent that any shares of SGB common stock are subject to vesting restrictions, the same terms and conditions currently applicable to such shares of SGB common

TABLE OF CONTENTS

stock will continue to apply to the converted shares First Bancshares common stock received in connection with the merger, except vesting shall be accelerated if the holder is terminated as an employee of First Bancshares within one year of the completion of the merger (other than for cause, death, disability, normal retirement or voluntary resignation). Mrs. Donna S. Lott and Messrs. Ross K. Dekle and Jeffrey (Jud) Moritz each hold 1,558, 5,737 and 5,825 unvested restricted stock awards, respectively.

Change of Control Payments and Benefits under Current SGB Employment Agreements.

SGB currently maintains an employment agreement with DeWitt Drew, its Chief Executive Officer. For the purposes of the employment agreement, the merger will constitute a “change in control.” Under the terms of the employment agreement, if Mr. Drew’s employment is terminated within six months prior to or eighteen months following a “change in control” (i) by SGB without “cause” (as defined in the agreement), or (ii) by Mr. Drew for “good reason” (as defined in the agreement), Mr. Drew will be entitled to receive his normal, current salary for the remainder of the employment term (as defined in the agreement) and paid insurance continuation rights under COBRA for the term. Under the employment agreement, “good reason” occurs when any of the following conditions exist, without Mr. Drew’s consent: the substantial adverse change in Mr. Drew’s responsibilities from those in effect immediately prior to the change in control or, after the change in control date, a reduction in Mr. Drew’s normal, current salary; a reduction in his incentive compensation resulting from a change in the incentive plan or the failure to continue to provide Mr. Drew with benefits substantially similar to those enjoyed by Mr. Drew under any of the employer’s pension, deferred compensation, life insurance, medical, or disability plans in which Mr. Drew was participating at the change in control date; the taking of any action which would directly or indirectly reduce any of such benefits or deprive Mr. Drew of any material fringe benefit enjoyed by Mr. Drew at the change in control date.

The employment agreement provides that amounts payable and benefits provided thereunder on account of a change in control shall be reduced to one dollar less than the maximum amount which may be paid without causing any such payment or benefit to be nondeductible as an “excess parachute payment” under Section 280G of the Internal Revenue Code. The employment agreement also contains non-competition and non-solicitation covenants that apply for two years following the executive’s termination of employment.

SGB and First Bancshares have agreed to terminate Mr. Drew’s employment agreement, with such termination to be effective at the effective time of the merger, and Mr. Drew will receive a lump sum payment of $586,838 net of applicable tax withholdings.

Employment Following the Merger

First Bancshares has entered into an employment agreement with Mr. Drew that will be effective as of the effective time of the merger and will terminate the later of (i) two weeks following operational conversion and integration of SGB with and into First Bancshares, and Southwest Georgia Bank with and into The First, which conversion and integration is anticipated to end no earlier than June 2020, and (ii) June 30, 2020. Pursuant to this agreement, Mr. Drew will receive base salary payments at the rate of $200,000 annually and continue to participate in his current split dollar plan. Under Mr. Drew’s agreement with First Bancshares, if his employment with First Bancshares is terminated by First Bancshares without cause (as defined in the agreement), Mr. Drew will be entitled to receive continuation of his base salary through the end of the employment agreement’s term. The agreement contains certain restrictive covenants, including a perpetual nondisclosure covenant with regard to trade secrets and a two-year nondisclosure covenant with regard to other confidential information. The agreement also contains covenants concerning noncompetition and nonsolicitation of employees and customers, each of which apply for two years following Mr. Drew’s termination of employment within the territory specified in the agreement.

To incentivize Mr. Drew to remain employed with First Bancshares following the merger, the agreement also provides that Mr. Drew will receive a lump-sum payment in the amount of $61,500 (less applicable tax withholdings), if he remains employed on the last day of the employment term or, if earlier, Mr. Drew’s employment is terminated by First Bancshares without cause.

TABLE OF CONTENTS

Indemnification; Directors’ and Officers’ Insurance

Pursuant to the terms of the merger agreement, directors and executive officers of SGB will be entitled to certain ongoing indemnification and coverage under directors’ and officers’ liability insurance policies following the merger. For additional information, see “The Merger Agreement — Indemnification and Directors’ and Officers’ Insurance”.

Merger-Related Compensation for SGB’s Named Executive Officers

This section sets forth the information required by Item 402(t) of Regulation S-K regarding the compensation for each of SGB’s named executive officers that is based on or otherwise relates to the merger. Mr. Drew is the only named executive officer receiving compensation that is based on or otherwise relates to the merger. SGB’s two other named executive officers — Mr. John J. Cole, Jr. and Mr. Jeffery E. Hanson — resigned effective December 31, 2018 and September 30, 2019, respectively, and are not receiving any compensation that is based on or otherwise relates to the merger.

The merger-related compensation payable to Mr. Drew by SGB is subject to a non-binding advisory vote of SGB’s shareholders, as described above in “SGB Proposals — Proposal Two: Compensation Proposal” and “— Interests of SGB’s Directors and Executive Officers in the Merger.”

The table below sets forth the approximate dollar value of the compensation for Mr. Drew that is based on or otherwise relates to the merger, assuming that the merger was completed and Mr. Drew experienced a qualifying termination on February 5, 2020.

Beneficial Ownership of SGB Common Stock by Management and Principal Shareholders of SGB

The following table sets forth information with respect to the beneficial ownership of shares of SGB common stock by the SGB directors, the SGB executive officers and the SGB directors and executive officers as a group, as well as information regarding each other person that SGB believes owns in excess of 5% of the outstanding shares of SGB common stock.

The percentages of beneficial ownership in the following table are calculated based upon 2,548,510 shares of SGB common stock issued and outstanding as of February 5, 2020. Beneficial ownership is determined in accordance with the rules of the SEC, which generally attribute beneficial ownership of securities to persons who possess sole or shared voting or investment power with respect to those securities, as well as shares issuable in connection with convertible securities exercisable or convertible within 60 days of the record date for the special meeting.

Unless otherwise indicated, and subject to the voting agreements entered into with SGB in connection with entering into the merger agreement, to SGB’s best knowledge, the persons or entities identified in the table below have sole voting and investment power with respect to all shares shown as beneficially owned by them.

Regulatory Approvals Required for the Merger

Completion of the merger is subject to prior receipt of all approvals required to be obtained from applicable governmental and regulatory authorities. Subject to the terms and conditions of the merger agreement, SGB and First Bancshares have agreed to use their reasonable best efforts and cooperate to prepare and file, as promptly as possible, all necessary documentation and to obtain as promptly as practicable all regulatory approvals or waivers required or advisable to complete the transactions contemplated by the merger agreement. These approvals and waivers include, among others, a waiver from the Federal Reserve Board and an approval from the OCC. First Bancshares and/or SGB have filed applications, waiver requests and notifications to obtain the required regulatory approvals or waivers.

Federal Reserve Board

The merger of SGB with First Bancshares must be approved by the Federal Reserve Board under Section 3 of the Bank Holding Company Act of 1956, or the BHC Act, and its implementing regulations, unless the Federal Reserve Board waives the application requirements of the BHC Act. In considering the approval of a transaction such as the merger, the BHC Act and related laws require the Federal Reserve Board to review, with respect to the parent holding companies and the bank concerned: (1) the competitive impact of the transaction; (2) financial, managerial and other supervisory considerations, including capital positions and managerial resources of the subject entities; (3) the record of the insured depository institution subsidiaries of the bank holding companies under the Community Reinvestment Act and fair lending laws; (4) the extent to which the proposal would result in greater or more concentrated risks to the stability of the U.S. banking or financial system; and (5) additional public benefits of the proposal, such as the benefits to the customers of the subject entities. In connection with its review, the Federal Reserve Board will provide an opportunity for public comment on the application and is authorized to hold a public meeting or other proceeding if it determines that would be appropriate. First Bancshares filed a written request that the Federal Reserve Board waive the application requirements of the BHC Act with regard to its acquisition of SGB on January 30, 2020.

Office of the Comptroller of the Currency

The merger of Southwest Georgia Bank with and into The First must be approved by the OCC under the National Bank Consolidation and Merger Act, 12 U.S.C. Section 215a. An application for approval of the bank merger was filed with the OCC on January 30, 2020. In evaluating such a merger application, the OCC generally considers: (1) the competitive impact of the transaction; (2) financial and managerial resources of the banks party to the bank merger or merger; (3) the convenience and needs of the community to be served and the record of the banks under the Community Reinvestment Act; (4) the banks’ effectiveness in combating money-laundering activities; and (5) the extent to which the bank merger or merger would result in greater or more concentrated risks to the stability of the U.S. banking or financial system. In connection with its review, the OCC will provide an opportunity for public comment on the application for the bank merger, and is authorized to hold a public meeting or other proceeding if it determines that would be appropriate.

First Bancshares and SGB believe that the merger does not raise substantial antitrust or other significant regulatory concerns and that we will be able to obtain all requisite regulatory approvals. However, neither First Bancshares nor SGB can assure you that all of the regulatory approvals described above will be obtained and, if obtained, we cannot assure you as to the timing of any such approvals, our ability to obtain the approvals on satisfactory terms or the absence of any litigation challenging such approvals. The parties have agreed that First Bancshares will not be required, and SGB and its subsidiaries will not be permitted, to take any action or commit to take any action or agree to any condition or restrictions in connection with the regulatory approvals that, individually or in the aggregate, would have or would be reasonably likely to have a material adverse effect on First Bancshares and its subsidiaries or SGB and its subsidiaries as of and following the completion of the merger.

The parties’ obligation to complete the merger is conditioned upon the receipt of all required regulatory approvals. First Bancshares and SGB will use their respective commercially reasonable efforts to resolve any objections that may be asserted by any regulatory authority with respect to the merger agreement or the merger or the other transactions contemplated by the merger agreement.

TABLE OF CONTENTS

Neither First Bancshares nor SGB is aware of any material governmental approvals or actions that are required for completion of the merger other than those described above. It is presently contemplated that if any such additional governmental approvals or actions are required, those approvals or actions will be sought. There can be no assurance, however, that any additional approvals or actions will be obtained.

Material U.S. Federal Income Tax Consequences

Subject to the limitations, assumptions and qualifications described herein, in the opinion of each of Alston & Bird LLP and Troutman Sanders LLP, the following discussion summarizes the material U.S. federal income tax consequences of the merger generally applicable to “U.S. holders” (as defined below) of SGB common stock that exchange their shares of SGB stock for shares of First Bancshares common stock, cash, or a combination thereof in the merger. The opinions of Alston & Bird LLP and Troutman Sanders LLP, tax counsel for each of First Bancshares and SGB, respectively, are filed as Exhibit 8.1 and Exhibit 8.2, respectively, to the registration statement on Form S-4 of which this document is a part.

This discussion is based upon the Code, its legislative history, the Treasury Regulations promulgated under the Code, and court and administrative rulings and decisions, all as in effect on the date of this proxy statement/prospectus, and all of which are subject to change, potentially retroactively, which could affect the accuracy of the statements and conclusions set forth in this discussion. The opinions described herein will not be binding on the Internal Revenue Service (the “IRS”) or any court. First Bancshares and SGB have not sought and will not seek any ruling from the IRS regarding any matters relating to the merger, and as a result, there can be no assurance that the IRS will not assert, or that a court would not sustain, a position contrary to any of the conclusions set forth below. In addition, if any of the representations or assumptions upon which the opinion is based are inconsistent with the actual facts, the U.S. federal income tax consequences of the merger could be adversely affected.

For purposes of this discussion, the term “U.S. holder” means a beneficial owner of SGB common stock that is for U.S. federal income tax purposes: (a) an individual citizen or resident of the United States; (b) a corporation (or any other entity treated as a corporation for U.S. federal income tax purposes) organized in or under the laws of the United States or any state thereof or the District of Columbia; (c) a trust if (1) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have the authority to control all substantial decisions of the trust or (2) such trust has made a valid election to be treated as a U.S. person for U.S. federal income tax purposes; or (d) an estate, the income of which is includible in gross income for U.S. federal income tax purposes regardless of its source.

If a partnership (including an entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds SGB common stock, the tax treatment of a partner in the partnership generally will depend on the status of such partner and the activities of the partnership. Any entity that is treated as a partnership for U.S. federal income tax purposes that holds SGB common stock and any partners in such partnerships should consult their tax advisors.

The discussion is based on the Code, the U.S. Treasury regulations promulgated thereunder, published positions of the IRS, and judicial decisions, all as currently in effect and all of which are subject to change (possibly with retroactive effect) and to differing interpretations. Any such change could affect the accuracy of the statements and conclusions set forth in this discussion. This discussion addresses only those U.S. holders of SGB common stock that hold their shares of SGB common stock as a “capital asset” within the meaning of Section 1221 of the Code (generally, property held for investment). Importantly, this discussion does not address all aspects of U.S. federal income taxation that may be relevant to a particular U.S. holder in light of that U.S. holder’s individual circumstances or to a U.S. holder that is subject to special treatment under the U.S. federal income tax laws, including, without limitation, a U.S. holder that is:

•

a bank or other financial institution;

•

a tax-exempt organization;

•

a regulated investment company;

•

a real estate investment trust;

TABLE OF CONTENTS

•

a mutual fund;

•

an S corporation, partnership or other pass-through entity (or an investor in an S corporation, partnership or other pass-through entity);

•

a retirement plan, individual retirement account or other tax-deferred account;

•

an insurance company;

•

a dealer or broker in stocks and securities, or currencies;

•

a trader in securities that elects to use the mark-to-market method of accounting;

•

a holder of SGB common stock subject to the alternative minimum tax provisions of the Code;

•

a holder of SGB common stock that received SGB common stock through the exercise of an employee stock option, through a tax-qualified retirement plan or otherwise as compensation;

•

a holder of SGB common stock that has a functional currency other than the U.S. dollar;

•

a holder of SGB common stock that holds such stock as part of a hedge, straddle, constructive sale, conversion or other integrated transaction;

•

a holder required to accelerate the recognition of any item of gross income for U.S. federal income tax purposes with respect to First Bancshares common stock as a result of such item being taken into account in an applicable financial statement;

•

a person that is not a U.S. holder; or

•

a U.S. expatriate or former citizen or resident of the United States.

This discussion does not address any tax consequences arising under the laws of any U.S. state, local or foreign jurisdiction, the Medicare contribution tax, or under any U.S. federal laws other than those pertaining to the income tax(such as estate or gift tax laws), nor does it address any considerations in respect of any withholding required pursuant to the Foreign Account Tax Compliance Act of 2010 (including the U.S. Treasury regulations issued thereunder and intergovernmental agreements entered into pursuant thereto). Determining the actual tax consequences of the merger to a U.S. holder is complex and can depend, in part, on the U.S. holder’s specific situation. Each U.S. holder should consult its own independent tax advisor as to the tax consequences of the merger in its particular circumstance, including the applicability and effect of the alternative minimum tax and any state, local, foreign or other tax laws and of changes in those laws.

Tax Consequences of the Merger Generally

Subject to the limitations, assumptions and qualifications described herein, the merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code. The obligations of the parties to complete the merger are conditioned on, among other things, the receipt by First Bancshares and SGB of opinions from Alston & Bird LLP and Troutman Sanders LLP, respectively, dated the closing date of the merger, to the effect that for U.S. federal income tax purposes the merger will be treated as a “reorganization” within the meaning of Section 368(a) of the Code.

These opinions of Alston & Bird LLP and Troutman Sanders LLP provided to First Bancshares and SGB, respectively, will be subject to customary qualifications and assumptions, including assumptions regarding the absence of changes in existing facts and the completion of the merger strictly in accordance with the merger agreement and the registration statement of which this proxy statement/prospectus forms a part. In rendering their legal opinions, Alston & Bird LLP and Troutman Sanders LLP will rely upon representations and covenants of First Bancshares and SGB, including those representations contained in certificates of officers of First Bancshares and SGB, reasonably satisfactory in form and substance to each such counsel, and will assume that such representations are true, correct and complete without regard to any knowledge limitation and that such covenants will be complied with. If any of these assumptions or representations are inaccurate in any way, or any of the covenants are not complied with, these opinions could be adversely affected. The opinions represent each counsel’s best legal judgment, but will not be binding on the IRS or any court, and no assurance can be given that contrary positions will not be taken by

TABLE OF CONTENTS

the IRS or a court considering the issues described herein. In addition, neither SGB nor First Bancshares has requested nor does either of them intend to request a ruling from the IRS as to the U.S. federal income tax consequences of the merger. Accordingly, there can be no assurances that the IRS will not assert, or that a court will not sustain, a position contrary to any of the tax consequences set forth below or described in the tax opinions.

The remainder of this discussion assumes that the merger qualifies as a “reorganization” within the meaning of Section 368(a) of the Code.

U.S. Holders that Exchange SGB Common Stock for First Bancshares Common Stock

Subject to the discussion below relating to the receipt of cash in lieu of a fractional share, a U.S. holder that exchanges all of its SGB common stock solely for shares of First Bancshares common stock generally:

•

will not recognize any gain or loss upon the exchange of shares of SGB common stock for shares of First Bancshares common stock in the merger;

•

will have a tax basis in the First Bancshares common stock received in the merger (including any fractional share deemed received and redeemed for cash as described below) equal to the tax basis of the SGB common stock surrendered in exchange therefor; and

•

will have a holding period for shares of First Bancshares common stock received in the merger that includes its holding period for its shares of SGB common stock surrendered in exchange therefor.

Cash In Lieu of a Fractional Share

If a U.S. holder receives cash in lieu of a fractional share of First Bancshares common stock, the U.S. holder generally will be treated as having received the fractional share of First Bancshares common stock in the merger and then as having sold the fractional share of First Bancshares common stock for cash. As a result, the U.S. holder generally will recognize gain or loss equal to the difference between the amount of cash received and the portion of the U.S. holder’s aggregate tax basis allocable to the fractional share of First Bancshares common stock. This gain or loss generally will be capital gain or loss, and will be long-term capital gain or loss if the U.S. holder has held its shares of SGB common stock for more than one year as of the effective time of the merger. In general, long-term capital gains for non-corporate taxpayers may be eligible for a reduced rate of taxation. The deductibility of capital losses may be subject to limitations.

Backup Withholding

Backup withholding at the applicable rate (currently 24%) may apply with respect to certain cash payments to holders of SGB common Stock unless the holder:

•

furnishes a correct taxpayer identification number, certifies that it is not subject to backup withholding on IRS Form W-9 or successor form included in the letter of transmittal that the U.S. holder will receive and otherwise complies with all the applicable requirements of the backup withholding rules; or

•

provides proof that it is otherwise exempt from backup withholding.

Any amounts withheld under the backup withholding rules are not an additional tax and generally will be allowed as a refund or credit against the U.S. holder’s U.S. federal income tax liability, provided the U.S. holder timely furnishes the required information to the IRS.

Certain Reporting Requirements

If a U.S. holder that receives First Bancshares common stock in the merger is considered a “significant holder,” such U.S. holder generally will be required (a) to file a statement with its U.S. federal income tax return providing certain facts pertinent to the merger, including such U.S. holder’s tax basis in, and the fair market value of, the SGB common stock surrendered by such U.S. holder, and (b) to retain permanent

TABLE OF CONTENTS

records of these facts relating to the merger. A “significant holder” is any SGB Shareholder that, immediately before the merger, (y) owned at least 5% (by vote or value) of the outstanding stock of SGB or (z) owned SGB securities with a tax basis of $1.0 million or more.

This discussion of material U.S. federal income tax consequences does not purport to be a complete analysis or discussion of all the potential tax consequences of the merger. It is for general information only purposes and is not tax advice. Holders of SGB common stock are urged to consult their own independent tax advisors as to the U.S. federal income tax consequences, in light of their particular situations, of the merger (or exercise of dissenters’ rights), as well as the applicability of any other U.S. federal tax laws and any state, local, and foreign tax laws.

Accounting Treatment

The merger will be accounted for under the acquisition method of accounting for business combinations under GAAP. Under this method, SGB’s assets and liabilities as of the date of the merger will be recorded at their respective fair values. Any difference between the purchase price for SGB and the fair value of the identifiable net assets acquired (including core deposit intangibles) will be recorded as goodwill. In accordance with ASC Topic 805, “Business Combinations,” the goodwill resulting from the merger will not be amortized to expense, but instead will be reviewed for impairment at least annually and to the extent goodwill is impaired, its carrying value will be written down to its implied fair value and a charge will be made to earnings. Core deposit and other intangibles with definite useful lives recorded by First Bancshares in connection with the merger will be amortized to expense in accordance with such rules. The consolidated financial statements of First Bancshares issued after the merger will reflect the results attributable to the acquired operations of SGB beginning on the date of completion of the merger.

Dissenters’ Rights

The merger agreement contemplates dissenters’ rights, however, under Article 13 of the GBCC, SGB shareholders will not be entitled to dissenters’ rights in connection with the merger if, on the record date for the SGB special meeting, their shares are listed on a national securities exchange or held of record by more than 2,000 shareholders, and they accept as consideration for their shares the shares of the surviving corporation or another publicly held corporation which at the effective date of the merger are either listed on a national securities exchange or held of record by more than 2,000 shareholders, except for cash paid in lieu of fractional shares. The SGB common stock is currently listed on NYSE American, a national securities exchange, and is expected to continue to be so listed on the record date for the SGB special meeting. The SGB shareholders will receive shares of First Bancshares common stock as merger consideration, which are currently listed on NASDAQ, and are expected to continue to be so listed at the effective date of the merger. Accordingly, the SGB shareholders will not be entitled to any dissenters’ rights in connection with the merger.

Exchange of Shares in the Merger

The conversion of SGB common stock into the right to receive the merger consideration will occur automatically at the effective time of the merger. After completion of the merger, the exchange agent will exchange certificates representing shares of SGB common stock for the merger consideration to be received pursuant to the terms of the merger agreement. For more information regarding the procedures for exchanging your shares of SGB common stock for the merger consideration, see “The Merger Agreement — Procedures for Converting Shares of SGB Common Stock into Merger Consideration” below.

Listing of First Bancshares Common Stock

First Bancshares has agreed to use its commercially reasonable efforts to cause the shares of First Bancshares common stock issuable in connection with the merger be approved for listing on the NASDAQ Global Market, subject to official notice of issuance, prior to the effective time of the merger.

TABLE OF CONTENTS

THE MERGER AGREEMENT

The following describes certain aspects of the merger, including certain material provisions of the merger agreement. The following description of the merger agreement is subject to, and qualified in its entirety by reference to, the merger agreement, which is attached to this proxy statement/prospectus as Annex A and is incorporated by reference into this proxy statement/prospectus. We urge you to read the merger agreement carefully and in its entirety, as it is the legal document governing the merger.

Structure of the Merger

The boards of directors of First Bancshares and SGB have each unanimously approved the merger agreement, which provides for the merger of SGB with and into First Bancshares, with First Bancshares as the surviving company in the merger.

The merger agreement also provides that immediately after the effective time of the merger but in effect simultaneously on the date the merger closes, Southwest Georgia Bank, which is a Georgia state-chartered bank and a direct wholly owned subsidiary of SGB, will merge with and into The First, a direct wholly owned subsidiary of First Bancshares, with The First as the surviving bank of such merger. The terms and conditions of the merger of The First and Southwest Georgia Bank are set forth in a separate merger agreement and plan of merger, referred to as the bank merger agreement, the form of which is attached as Exhibit B to the merger agreement. As provided in the bank merger agreement, the merger of The First and Southwest Georgia Bank may be abandoned at the election of The First at any time, whether before or after filings are made for regulatory approval of such merger. We refer to the merger of The First and Southwest Georgia Bank as the bank merger.

The merger agreement allows First Bancshares to change the structure of the merger at any time and without the approval of SGB if and to the extent that First Bancshares reasonably deems such a change to be necessary; provided, however, that no such change shall (i) alter or change the amount or kind of merger consideration to be provided under the merger agreement, (ii) materially impede or delay consummation of the merger, (iii) adversely affect the federal income tax treatment of SGB shareholders in connection with the merger, or (iv) require submission to or the approval of SGB shareholders after the merger proposal has already been approved by SGB’s shareholders.

Closing and Effective Time of the Merger

The closing will take place immediately prior to the effective time of the merger. The effective time of the merger will be the later of (i) the date and time of filing of the articles of merger with the Secretary of State of the State of Mississippi and the Secretary of State of the State of Georgia by First Bancshares or (ii) the date and time when the merger becomes effective as set forth in such articles of merger, which will be no later than three business days after all of the conditions to the closing of the merger have been satisfied or waived in accordance with their terms.

We currently expect that the merger will be completed in the second quarter of 2020, subject to obtaining the requisite approvals from the shareholders of SGB, the receipt of all necessary regulatory approvals and the expiration of all regulatory waiting periods and other conditions. However, completion of the merger could be delayed if there is a delay in obtaining the required regulatory approvals or in satisfying any other conditions to the merger. No assurance is made as to whether, or when, First Bancshares and SGB will obtain the required approvals or complete the merger. See “The Merger Agreement — Conditions to Completion of the Merger.”

Organizational Documents of the Surviving Company

At the effective time of the merger, the First Bancshares Articles and the First Bancshares Bylaws in effect immediately prior to the effective time of the merger will be the articles of incorporation and bylaws of the surviving company until thereafter amended in accordance with their respective terms and applicable laws.

Board Composition and Management of Surviving Company

TABLE OF CONTENTS

merger, until their respective successors have been duly elected, appointed or qualified or until their earlier death, resignation or removal in accordance with the First Bancshares Articles and the First Bancshares Bylaws.

Merger Consideration

Under the terms of the merger agreement, each share of SGB common stock issued and outstanding immediately prior to the effective time of the merger will be converted into the right to receive 1.00, or the exchange ratio, share of First Bancshares common stock. To the extent that any shares of SGB common stock are subject to vesting restrictions, the same terms and conditions currently applicable to such shares of SGB common stock will continue to apply to the converted shares First Bancshares common stock received in connection with the merger, with certain exceptions where the holder of the shares of restricted stock is terminated as an employee of First Bancshares within one year of the completion of the merger (other than for cause, death, disability, normal retirement or voluntary resignation).

If First Bancshares or SGB change the number of shares of First Bancshares common stock or SGB common stock outstanding prior to the effective time of the merger as a result of a stock split, reverse stock split, stock combination, stock dividend, recapitalization, reclassification, reorganization or similar transaction with respect to First Bancshares common stock or SGB common stock and the record date for such corporate action is prior to the effective time of the merger, then the merger consideration shall be appropriately and proportionately adjusted to give SGB shareholders the same economic effect as contemplated by the merger agreement prior to any such event.

The value of the shares of First Bancshares common stock to be issued to SGB shareholders in the merger will fluctuate between now and the closing date of the merger. We make no assurances as to whether or when the merger will be completed, and you are advised to obtain current sale prices for the First Bancshares common stock.

Procedures for Converting Shares of SGB Common Stock into Merger Consideration

Exchange Agent

First Bancshares will designate a third party to act as the exchange agent in connection with the merger. The exchange agent shall also act as the agent for SGB shareholders for the purpose of receiving their SGB stock certificates and shall obtain no rights or interests in the shares represented thereby. Prior to the effective time of the merger, First Bancshares will deposit, or cause to be deposited, with the exchange agent the aggregate merger consideration and, to the extent then determinable, any cash payable in lieu of fractional shares, necessary to satisfy the aggregate merger consideration payable.

Transmittal Materials and Procedures

Promptly (but not more than three business days) after the effective time of the merger, First Bancshares will cause the exchange agent to send transmittal materials, which will include the appropriate form of letter of transmittal, to holders of record of shares of SGB common stock (other than excluded shares) providing instructions on how to effect the delivery of certificates or book-entry shares of SGB common stock in exchange for the merger consideration. After the effective time of the merger, when a SGB shareholder surrenders his or her stock certificates or book-entry shares, accompanied by a properly executed letter of transmittal and any other documents as may reasonably be required by the exchange agent, the holder of shares of SGB common stock will be entitled to receive, (i) the merger consideration and (ii) any cash in lieu of fractional shares to which the holder is entitled.

Surrender of SGB Stock Certificates

The exchange agent will mail to each holder of record of SGB common stock the letter of transmittal along with instructions for completing the letter of transmittal and delivering to the exchange agent the completed letter of transmittal along with the stock certificates or book-entry shares representing the shares of SGB common stock held by the shareholder.

TABLE OF CONTENTS

Following the effective time of the merger, upon the surrender to the exchange agent of the certificate(s) or book-entry shares representing his or her shares of SGB common stock, accompanied by a properly completed letter of transmittal, a SGB shareholder will be entitled to receive the merger consideration promptly after the effective time of the merger (including any cash in lieu of fractional shares). Until surrendered, each such certificate or book-entry share will represent after the effective time of the merger, for all purposes, only the right to receive the merger consideration, without interest (including any cash in lieu of fractional shares), and any dividends to which such holder is entitled pursuant to the merger agreement.

No dividends or other distributions with respect to First Bancshares common stock after completion of the merger will be paid to the holder of any unsurrendered SGB stock certificates or book-entry shares with respect to the shares of SGB common stock represented by those certificates until those certificates or book-entry shares have been properly surrendered. Subject to applicable abandoned property, escheat or similar laws, following the proper surrender of any such previously unsurrendered SGB stock certificate or book-entry shares, the holder of the certificate or book-entry shares will be entitled to receive, without interest: (i) the amount of unpaid dividends or other distributions with a record date after the effective time of the merger payable with respect to the whole shares of First Bancshares common stock represented by that certificate or book-entry shares; and (ii) at the appropriate payment date, the amount of dividends or other distributions payable with respect to shares of First Bancshares common stock represented by that certificate or the book-entry shares with a record date after the effective time of the merger (but before the date on which the certificate or book-entry shares are surrendered) and with a payment date subsequent to the issuance of the shares of First Bancshares common stock issuable in exchange for that certificate or book-entry shares.

None of First Bancshares, the exchange agent or any other person will be liable to any former SGB shareholder for any amount delivered in good faith to a public official pursuant to applicable abandoned property, escheat or similar laws.

In the event any SGB stock certificate is lost, stolen or destroyed, in order to receive the merger consideration (including cash in lieu of any fractional shares), the holder of that certificate must provide an affidavit of that fact and, if reasonably required by First Bancshares or the exchange agent, post a bond in such amount as First Bancshares or the exchange agent determines is reasonably necessary to indemnify it against any claim that may be made against it with respect to that certificate.

First Bancshares and the exchange agent will be entitled to deduct and withhold from the consideration otherwise payable to any SGB shareholder the amounts they are required to deduct and withhold under any applicable federal, state, local or foreign tax law. If any such amounts are withheld, these amounts will be treated for all purposes of the merger agreement as having been paid to the shareholders from whom they were withheld.

After completion of the merger, there will be no further transfers on the stock transfer books of SGB other than to settle transfers of SGB common stock that occurred prior to the effective time of the merger.

No interest will be paid or accrued on any amount payable upon cancellation of shares of SGB common stock. The shares of First Bancshares common stock issued and cash amount paid in accordance with the merger agreement upon conversion of the shares of SGB common stock (including any cash paid in lieu of fractional shares) will be deemed to have been issued and paid in full satisfaction of all rights pertaining to the shares of SGB common stock.

If any portion of the merger consideration is to be delivered to a person or entity other than the holder in whose name any surrendered certificate is registered, it will be a condition of such exchange that (i) the certificate surrendered must be properly endorsed or must be otherwise in proper form for transfer and (ii) the person or entity requesting such payment pays any transfer or other similar taxes required by reason of the payment of the merger consideration to a person or entity other than the registered holder of the certificate surrendered or will establish to the satisfaction of First Bancshares that such tax has been paid or is not required to be paid. Payment of the applicable merger consideration with respect to book-entry shares will only be made to the person or entity in whose name such book-entry shares are registered. The shares of First Bancshares common stock may be in uncertificated book-entry form, unless a physical certificate is otherwise required by any applicable law.

Definition of “Material Adverse Effect”

Certain representations and warranties of First Bancshares and SGB are qualified as to “materiality” or “material adverse effect.” For purposes of the merger agreement, a “material adverse effect,” when used in reference to either First Bancshares or SGB, means (i) any change, development or effect that individually or in the aggregate is, or is reasonably likely to be, material and adverse to the condition (financial or otherwise), results of operations, liquidity, assets or deposit liabilities, properties, or business of such party and its subsidiaries, taken as a whole, or (ii) any change, development or effect that individually or in the aggregate would, or would be reasonably likely to, materially impair the ability of such party to perform its obligations under the merger agreement or otherwise materially impairs, or is reasonably likely to materially impair, the ability of such party to consummate the merger and the transactions contemplated by the merger agreement.

except, with respect to the first three bullets, if the effects of such change disproportionately affect such party and its subsidiaries, taken as a whole, as compared to other companies in the industry in which such party and its subsidiaries operate.

TABLE OF CONTENTS

First Bancshares has also agreed to use its commercially reasonable efforts to obtain all necessary state securities law or “blue sky” permits and approvals required to carry out the transactions contemplated by the merger agreement.

First Bancshares and SGB and their respective subsidiaries have agreed to cooperate with each other and use their reasonable best efforts to prepare and file all necessary documentation, to effect all filings, to obtain as promptly as practicable all permits, consents, approvals and authorizations of all third parties and regulatory and governmental entities that are necessary to consummate the transactions contemplated by the merger agreement, and to comply with the terms and conditions of all such permits, consents, approvals and authorizations; provided, however, that nothing contained in the merger agreement will require First Bancshares or any of its subsidiaries or SGB or any of its subsidiaries to take any action, or commit to take any action, or agree to any condition or restriction, in connection with obtaining the foregoing permits, consents, approvals and authorizations of any governmental authority that would reasonably be likely to have a material and adverse effect (measured on a scale relative to SGB) on the condition (financial or otherwise), results of operations, liquidity, assets or deposit liabilities, properties or business of First Bancshares, SGB, the surviving entity or the surviving bank, after giving effect to the merger (a “burdensome condition”).

First Bancshares and SGB will furnish each other and each other’s counsel with all information as may be necessary or advisable in connection with any application, petition or any other statement or application made by or on behalf of First Bancshares or SGB to any governmental authority in connection with the transactions contemplated by the merger agreement. Each party has the right to review and approve in advance all characterizations of the information relating to such party and any of its subsidiaries that appear in any filing with a governmental authority made in connection with the transactions contemplated by the merger agreement. In addition, First Bancshares and SGB agreed to provide to the other party for review a copy of each filing with a governmental authority made in connection with the transactions contemplated by the merger agreement prior to its filing.

NASDAQ Listing

First Bancshares has agreed to use its commercially reasonable efforts to cause the shares of its common stock to be issued in connection with the merger to be approved for listing on NASDAQ, subject to official notice of issuance, prior to the effective time of the merger.

Employee Matters

General

Following the effective time of the merger, First Bancshares must maintain employee benefit plans and compensation opportunities for those persons who are full-time employees of SGB and its subsidiaries on the closing date of the merger (referred to below as “covered employees”) that provide employee benefits which, in the aggregate, are substantially comparable to the employee benefits and cash-based compensation opportunities that are made available on a uniform and non-discriminatory basis to similarly situated employees of First Bancshares or its subsidiaries (except that no covered employee may participate in any closed or frozen plan of First Bancshares or its subsidiaries). First Bancshares shall give the covered employees credit for their prior service with SGB and its subsidiaries for purposes of eligibility and vesting under any employee benefit plan maintained by First Bancshares in which covered employees may be eligible to participate.

With respect to any First Bancshares health, dental, vision or other welfare plan in which any covered employee is eligible to participate, for the plan year in which the covered employee is first eligible to participate, First Bancshares or its applicable subsidiary must use its commercially reasonable efforts to (i) cause any pre-existing condition limitations or eligibility waiting periods under such plan to be waived with respect to the covered employee and his or her covered dependents to the extent the condition was, or would have been, covered under the SGB benefit plan in which the covered employee participated immediately prior to the effective time of the merger and (2) recognize any health, dental, vision or other welfare expenses incurred by such covered employee and his or her covered dependents in the year that

TABLE OF CONTENTS

includes the closing date (or, if later, the year in which such covered employee is first eligible to participate) for purposes of any applicable copayment, deductibles and annual out of pocket expense requirements under any such health, dental, vision or other welfare plan.

Employees of SGB (other than those who will enter into termination agreements with First Bancshares and/or The First in connection with the transaction) who (i) become employees of The First Bancshares or The First at the effective time of the merger and (ii) is terminated within one year following the effective time of the merger (other than for cause, death, disability, normal retirement or voluntarily resignation) will be entitled to receive severance compensation based on the number of years of service with SGB and the employees’ weekly rate of pay.

Prior to the effective time of the merger, SGB will effectuate the termination or discontinuation of certain benefits plans maintained by SGB, as requested by First Bancshares.

Indemnification and Directors’ and Officers’ Insurance

The merger agreement provides that, for a period of six years after the effective time of the merger, First Bancshares shall indemnify and hold harmless the present and former directors and officers of SGB and its subsidiaries against all costs or expenses, judgments, fines, losses, claims, damages or other liabilities incurred in connection with any claim, action, suit, proceeding or investigation arising out of actions or omissions of such persons in the course of performing their duties for SGB or its subsidiaries occurring at or before the effective time of the merger (including the transactions contemplated by the merger agreement), to the same extent as such persons have the right to be indemnified pursuant to the organizational documents of SGB in effect as of the date of the merger agreement to the extent permitted by applicable law. First Bancshares will also advance expenses in connection with such indemnification.

For a period of six years after the effective time of the merger, First Bancshares will provide directors’ and officers’ liability insurance that serves to reimburse the present and former officers and directors of SGB or its subsidiaries with respect to claims against them arising from facts or events occurring before the effective time of the merger (including the transactions contemplated by the merger agreement). The directors’ and officers’ liability insurance will contain at least the same coverage and amounts, and contain terms and conditions no less advantageous to the indemnified person as the coverage currently provided by SGB; provided, however, that: (i) if First Bancshares is unable to obtain or maintain the directors’ and officers’ liability insurance, then First Bancshares will provide as much comparable insurance as is reasonably available, and (ii) officers and directors of SGB or its subsidiaries may be required to make application and provide customary representations and warranties to the carrier of the insurance. First Bancshares will not be required to expend for such tail insurance a premium amount in excess of an amount equal to 200% of the annual premiums paid by SGB for director and officer insurance in effect as of the date of this Agreement.

First Bancshares has agreed that if it, or any of its successors and assigns, consolidates with or merges with any other corporation or entity where it is not the continuing or surviving corporation, or transfers all or substantially all of its property or assets, it will make proper provision so that the successors and assigns of First Bancshares and its subsidiaries will assume the obligations of indemnification under the merger agreement.

No Solicitation

SGB has agreed that, from the date of the merger agreement it will not, and will cause its subsidiaries and each of their respective officers, directors and employees not to, and will not authorize or permit its investment bankers, financial advisors, attorneys, accountants, consultants, affiliates or other agents of SGB or any of its subsidiaries to, directly or indirectly, (i) initiate, solicit, induce or knowingly encourage, or take any action to facilitate the making of, any inquiry, offer or proposal which constitutes, or could reasonably be expected to lead to, an acquisition proposal; (ii) participate in any discussions or negotiations regarding any acquisition proposal or furnish, or otherwise afford access, to any person (other than First Bancshares) any information or data with respect to SGB or any of its subsidiaries in connection with a potential acquisition proposal; (iii) release any person from, waive any provisions of, or fail to enforce any

TABLE OF CONTENTS

confidentiality agreement or standstill agreement to which SGB is a party; or (iv) enter into any agreement, confidentiality agreement, agreement in principle or letter of intent with respect to any acquisition proposal or approve or resolve to approve any acquisition proposal or any agreement, agreement in principle or letter of intent relating to an acquisition proposal.

For purposes of the merger agreement, an “acquisition proposal” means (A) any transaction or series of transactions involving any merger, consolidation, recapitalization, share exchange, liquidation, dissolution or similar transaction involving SGB or any of its subsidiaries; (B) any transaction pursuant to which any third party or group acquires or would acquire (whether through sale, lease or other disposition), directly or indirectly, the assets of SGB or any of its subsidiaries, constituting, in the aggregate, 20% or more of the fair value of the consolidated assets of SGB; (C) any issuance, sale or other disposition of (including by way of merger, consolidation, share exchange or any similar transaction) securities (or options, rights or warrants to purchase or securities convertible into, such securities) representing 20% or more of the votes attached to the outstanding securities of SGB or any of its subsidiaries; (D) any tender offer or exchange offer that, if consummated, would result in any third party or group beneficially owning 20% or more of any class of equity securities of SGB or any of its subsidiaries; or (E) any transaction which is similar in form, substance or purpose to any of the foregoing transactions, or any combination of the foregoing.

However, at any time prior to SGB special meeting, SGB may take any of the actions described in the first paragraph of this “— No Solicitation” section if, but only if (i) SGB receives a bona fide unsolicited acquisition proposal that did not result from a breach of the first paragraph of this section, and (ii) the SGB board of directors reasonably determines in good faith, after consultation with and having considered the advice of its outside financial advisor and outside legal counsel, that (A) such acquisition proposal constitutes or is reasonably likely to lead to a superior proposal and (B) the failure to take such actions would reasonably be expected to cause it to breach its fiduciary duties under applicable law, (iii) SGB has provided First Bancshares with at least two business days prior notice of such determination, and (iv) prior to furnishing or affording access to any information or data with respect to SGB or any of its subsidiaries or otherwise relating to an acquisition proposal, SGB receives from such person a confidentiality agreement with terms no less favorable to SGB than those contained in the confidentiality agreement with First Bancshares. SGB must promptly provide to First Bancshares any non-public information regarding SGB or any of its subsidiaries provided to any other person which was not previously provided to First Bancshares, and such additional information must be provided no later than the date of provision of such information to such other party.

A “superior proposal” means a bona fide, unsolicited acquisition proposal (i) that if consummated would result in a third party (or in the case of a direct merger between such third party and SGB or any of its subsidiaries, the shareholders of such third party) acquiring, directly or indirectly, more than 50% of the outstanding SGB common stock or more than 50% of the assets of SGB and its subsidiaries (measured as a percentage of the fair value of the consolidated assets of SGB), taken as a whole, for consideration consisting of cash and/or securities and (ii) that the board of directors of SGB reasonably determines in good faith, after consultation with its outside financial advisor and outside legal counsel, (a) is reasonably capable of being completed, taking into account all financial, legal, regulatory and other aspects of such proposal, including all conditions contained therein and the person making such acquisition proposal, and (b) taking into account any changes to the merger agreement proposed by First Bancshares in response to such acquisition proposal, and all financial, legal, regulatory and other aspects of such proposal, including all conditions contained therein and the person making such acquisition proposal, such proposal is more favorable to the shareholders of SGB from a financial point of view than the merger.

SGB must promptly (and in any event within 24 hours) notify First Bancshares in writing if any proposals or offers are received by, any information is requested from, or any negotiations or discussions are sought to be initiated or continued with, SGB or its representatives, in each case in connection with any acquisition proposal, and such notice must indicate the name of the person initiating such discussions or negotiations or making such proposal, offer or information request and the material terms and conditions of any proposals or offers (and, in the case of written materials relating to such proposal, offer, information request, negotiations or discussion, providing copies of such materials (including e-mails or other electronic communications), except to the extent that such materials constitute confidential information of the party

TABLE OF CONTENTS

making such offer or proposal under an effective confidentiality agreement). SGB has agreed that it will keep First Bancshares informed, on a reasonably current basis, of the status and terms of any such proposal, offer, information request, negotiations or discussions (including any amendments or modifications to such proposal, offer or request).

Except as provided below, neither the board of directors of SGB nor any committee thereof shall (i) fail to make or withdraw (or modify or qualify in any manner adverse to First Bancshares or publicly propose to withdraw, modify, or qualify in any manner adverse to First Bancshares) the SGB recommendation, or the determination of the advisability to its shareholders of the approval of the merger agreement and the transactions contemplated by the merger agreement (including the merger); (ii) adopt, approve or publicly recommend, endorse or otherwise declare advisable any acquisition proposal; (iii) fail to include the SGB recommendation in whole or in part in the proxy statement prospectus or any filing or amendment or supplement relating thereto; (iv) fail to recommend against any then-pending tender or exchange offer that constitutes an acquisition proposal within five business days after it is announced; (v) fail to reaffirm the SGB recommendation within three business days following a request by First Bancshares, or make any statement, filing or release, in connection with the SGB meeting or otherwise, inconsistent with the SGB recommendation; or (vi) resolve to do any of the foregoing.

Notwithstanding the foregoing, prior to the receipt of the requisite SGB shareholder approval, the board of directors of SGB may withdraw, qualify, amend or modify the SGB recommendation (“SGB subsequent determination”) or cause or permit SGB to terminate the merger agreement to enter into a definitive agreement with respect to such Superior Proposal after the fifth business day following First Bancshares’ receipt of a notice (the “notice of superior proposal”) from SGB advising First Bancshares that the board of directors of SGB has decided that a bona fide unsolicited written acquisition proposal that it received (that did not result from a breach of the merger agreement) constitutes a superior proposal if, but only if, (i) the board of directors of SGB has determined in good faith, after consultation with and having considered the advice of outside legal counsel and its financial advisor, that the failure to take such actions would reasonably be expected to cause it to violate its fiduciary duties to SGB’s shareholders under applicable law, (ii) during the five business day period after receipt of the notice of superior proposal by First Bancshares (the “notice period”), SGB and the board of directors of SGB shall have cooperated and negotiated in good faith with First Bancshares to make such adjustments, modifications or amendments to the terms and conditions of the merger agreement as would enable SGB to proceed with the SGB recommendation in favor of the merger with First Bancshares without a SGB subsequent determination; provided, however, that First Bancshares does not have any obligation to propose any adjustments, modifications or amendments to the terms and conditions of the merger agreement and (iii) at the end of the notice period, after taking into account any such adjusted, modified or amended terms as may have been proposed by First Bancshares since its receipt of such notice of superior proposal, the board of directors of SGB has again in good faith made the determination that such acquisition proposal constitutes a superior proposal. In the event of any material revisions to the superior proposal, SGB is required to deliver a new notice of superior proposal to First Bancshares and again comply with the foregoing requirements, except that the notice period will be reduced to three business days.

Notwithstanding any SGB subsequent determination, the merger agreement will be submitted to SGB’s shareholders at the SGB special meeting for the purpose of voting on the approval of the merger proposal and nothing contained in the merger agreement will be deemed to relieve SGB of such obligation; provided, however, that if the board of directors of SGB makes a SGB subsequent determination with respect to a superior proposal, then the board of directors of SGB may recommend approval of such superior proposal by the shareholders of SGB and may submit the merger proposal to SGB’s shareholders without recommendation, in which event the board of directors of SGB will communicate the basis for its recommendation of such superior proposal and the basis for its lack of a recommendation with respect to the merger proposal to SGB’s shareholders in an appropriate amendment or supplement to this proxy statement/prospectus.

To obtain copies of these documents, see “Where You Can Find More Information.” First Bancshares common stock is listed on the NASDAQ Global Market under the symbol “FBMS.”

Common Stock

Authorized. First Bancshares has 40,000,000 shares of authorized common stock, $1.00 par value. As of [ ], 2020, there were [ ] shares of common stock issued and outstanding.

Voting Rights; Cumulative Voting. Pursuant to the MBCA and the First Bancshares Bylaws, each outstanding share of the First Bancshares common stock is entitled to one vote on each matter submitted to a vote. Holders of the First Bancshares common stock do not have cumulative voting rights. Article 2.6 of the First Bancshares Bylaws provides that unless otherwise required by the MBCA or the articles of incorporation, all classes or series of First Bancshares 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 First Bancshares Articles, the board of directors of First Bancshares 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 2020 Annual Shareholders’ Meeting. The terms of the Class II directors will expire at the 2021 Annual Shareholders’ Meeting. The terms of the Class III directors will expire at the 2019 Annual Shareholders’ Meeting.

Dividends. First Bancshares 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 First Bancshares 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 First Bancshares 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. Approval by First Bancshares’ regulators is required if the total of all dividends declared in any calendar year exceeds the total of its net income for that year combined with its retained net income of the preceding two years.

Under certain conditions, dividends paid to First Bancshares by The First are subject to approval by the OCC. A national bank may not pay dividends from its capital. All dividends must be paid out of undivided profits then on hand, after deducting expenses, including reserves for losses and bad debts. In addition, a national bank is prohibited from declaring a dividend on its shares of common stock until its surplus equals its stated capital, unless the bank has transferred to surplus no less than one-tenth of its net profits of the preceding two consecutive half-year periods (in the case of an annual dividend). The approval of the OCC is required if the total of all dividends declared by a national bank in any calendar year exceeds the total of its net profits for that year combined with its retained net profits for the preceding two years, less any required transfers to surplus. In addition, under the Federal Deposit Insurance Corporation Improvement Act, banks may not pay a dividend if, after paying the dividend, the bank would be undercapitalized.

Preemptive Rights; Liquidation. First Bancshares common stock does not carry any preemptive rights enabling a holder to subscribe for or receive shares of First Bancshares common stock. In the event of liquidation, holders of First Bancshares 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 First Bancshares preferred stock, if any such shares are outstanding. There are no redemption or sinking fund provisions applicable to First Bancshares common stock.

Preferred Stock

Under the terms of the First Bancshares Articles, First Bancshares 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 First Bancshares 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. First Bancshares Articles authorize First Bancshares’ 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 First Bancshares 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 First Bancshares Articles do not provide for a greater than majority vote on such a transaction.

The First Bancshares Articles 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 First Bancshares describing the person’s background and the control share acquisition and requesting a special meeting of shareholders of First Bancshares 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 First Bancshares, 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 First Bancshares Articles provide that no director of First Bancshares 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 First Bancshares 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 First Bancshares 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

TABLE OF CONTENTS

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 First Bancshares, unless such power is expressly reserved for the shareholders. Article 10 of the First Bancshares 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 First Bancshares 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 First Bancshares 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 First Bancshares not less than 50 nor more than 90 days prior to the meeting at which directors are to be elected, provided that First Bancshares has mailed the first notice of the meeting at least 60 days prior to the meeting date. If First Bancshares 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 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 First Bancshares Articles provides that no director of First Bancshares shall be personally liable to First Bancshares 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 First Bancshares Bylaws also provides for indemnification of directors and officers.

The SGB Bylaws require a written notice of each shareholders’ meeting stating the place, date and hour of the meeting to be delivered personally or by mail to each shareholder of record entitled to vote at such meeting not less than 10 days, nor more than 50 days before the date of the meeting.

The notice of a special meeting, however, must state the general nature of the business to be transacted at the meeting.
Liability and Indemnification of Directors and Officers	The First Bancshares Bylaws require First Bancshares to indemnify its directors (referred to in this subsection as the indemnitees) against liability and reasonable expenses (including attorneys’ fees) incurred in connection with any proceeding an indemnitee is made a party to if he or she met the required standard of conduct. To meet the standard of conduct, the indemnitee must have conducted himself or herself in good faith, and he or she must have reasonably believed that any conduct was in First Bancshares’ best interests, or in any criminal proceeding, the indemnitee had no reasonable cause to believe his or her conduct was unlawful. Unless otherwise ordered by a court, First Bancshares is not obligated to indemnify an indemnitee in connection with (1) any appropriation, in violation of his duties, of any business opportunity of First Bancshares, (b) acts or omissions not in good faith or which involve intentional	The SGB Bylaws states that SGB may indemnify any person who is or was a director or officer of SGB or any other corporation of which he served as such at the request of SGB and of which SGB directly or indirectly is a shareholder or creditor, or in which SGB was interested in the stock, bonds, securities or other obligations, against liability and reasonable expenses incurred in connection with any claim, action, suit or proceeding, that such person is made a party to if he or she meets the required standard of conduct. To meet the standard of conduct, the director or officer must have conducted himself or herself in good faith, and he or she must have reasonably believed that any conduct was in SGB’s best interests, or in any criminal proceeding, the indemnitee had no reasonable cause to believe his or her conduct was unlawful. The SGB Bylaws state that any director or officer that (i) meets the standard of conduct and other requirements stated above, and (ii) has been wholly successful, on the

				misconduct or a knowing violation of law, (c) under Section 79-4-8.33 of the MBCA, or (d) any transaction from which the director derived an improper personal benefit. First Bancshares is allowed to extend its indemnification rights to any other officer, employee, or agent of the company upon a resolution of the board of directors to that effect. An indemnitee may apply to the court conducting the proceeding, or to another court, for indemnification or advance for expenses. The court shall (1) order indemnification if the court determines that the indemnitee is entitled to mandatory indemnification under applicable provisions of the MBCA or (2) order indemnification or advance for expenses if the court determines that (a) the indemnitee is entitled to indemnification or advance for expenses under the First Bancshares Bylaws or (b) in view of all relevant circumstances it is fair and reasonable to indemnify or advance expenses to such indemnitee even if he or she has not met the standard of conduct described above. First Bancshares must indemnify an indemnitee who is wholly successful, on the merits or otherwise, in the defense of any proceeding to which the indemnitee was a party against reasonable expenses incurred in the proceeding. First Bancshares generally must advance funds to pay for or reimburse the reasonable expenses incurred by an indemnitee who is a party to a proceeding.			merits or otherwise, with respect to such claim, is entitled to indemnification as of right without further action or approval by the board of directors. All other indemnification decisions will be made at the discretion of SGB, but only if (i) the board, acting by majority vote of a quorum consisting of directors who were not parties to such proceeding, find that the director or officer has met the standard of conduct, or (ii) if no such quorum of the board exists, independent legal counsel selected by a judge specified in the SGB Bylaws, at the request of either SGB or the person seeking indemnification, will deliver their written opinion on whether the director or officer has met such standards, or (iii) the holders of a majority of stock then entitled to vote for the election of directors will determine by affirmative vote that such director or officer has met such standards. Notwithstanding the foregoing, no officer or director will be indemnified in respect of any claim, issue or matter as to which such person has been adjudged to be liable for negligence or misconduct in the performance of his duty to SGB unless and except to the extent that the Court in which such action or suit was brought shall determine upon application that such person is fairly and reasonably entitled to indemnity for such expenses as the Court shall deem proper. Expenses incurred in defending any action referred to above may be paid by SGB in advance of the final disposition upon receipt of an undertaking by or on behalf of the recipient repay such amount unless it is ultimately determined that he is entitled to indemnification as provided above.

							Under the GBCC, a director may apply to the court conducting the proceeding, or to another court, for indemnification or advance for expenses. The court shall (1) order indemnification if the court determines that the indemnitee is entitled to indemnification or advance for expenses under applicable provisions of the GBCC, or (2) order indemnification or advance for expenses if the court determines, in view of all the relevant circumstances, that it is fair and reasonable to indemnify or advance expenses to the director even if he or she (i) has not met the standard of conduct described in the GBCC, (ii) failed to comply with the provisions of the GBCC, or (iii) was adjudged liable in a proceeding specified in the GBCC, but if the director was adjudged so liable, the indemnification shall be limited to reasonable expenses incurred in connection with the proceeding. The SGB Bylaws require that if any amounts are paid by way of indemnification, otherwise than by court order or action by the shareholders or by an insurance carrier pursuant to insurance maintained by the corporation, SGB will, not later than the next annual meeting of shareholders unless such meeting is held within three months from the date of such payment, and, in any event, within 15 months from the date of such payment, send by first class mail to its shareholders of record at the time entitled to vote for the election of directors a statement specifying the persons paid, the amounts paid, and the nature and status at the time of such payment of the litigation on threatened litigation.

	Limitation of Director Liability			The First Bancshares Articles provide that no director of First Bancshares will be personally liable to First Bancshares or its shareholders for monetary damages for breach of fiduciary duty as a director, unless he or she has (i) appropriated any business opportunity that rightly belonged to First Bancshares, (ii) acted or omitted to act not in good faith or which involves the intentional misconduct or a knowing violation of law, (iii) provided under Section 79-4-8.33 of the MBCA, or (iv) derived an improper personal benefit for any transaction. Under Miss. Code Ann. Section 81-5-105(1), the duties of a director or officer of a bank or bank holding company to the bank or bank holding company and its shareholders are to discharge the director’s or officer’s duties in good faith and with the diligence, care, judgment and skill as provided in subsection (2). Under Miss. Code Ann. Section 81-5-105(2), a director or officer of a bank or bank holding company cannot be held personally liable for money damages to a corporation or its shareholder unless the officer or director acts in a grossly negligent manner or engages in conduct that demonstrates a greater disregard of the duty of care than gross negligence. In addition, Miss. Code Ann. Section 81-5-105(4) provides that the provisions of Miss. Code Ann. Section 81-5-105 are the sole and exclusive law governing the relation and liability of directors and officers to their bank or bank holding company, or their successor, or to the shareholders thereof, or to any other person or entity. If the MBCA were applicable in defining the fiduciary duties of officers and directors, Miss. Code			The SGB Articles provide that no director of SGB will be personally liable to SGB or its shareholders for monetary damages for breach of his duty of care or other duty as a director; provided, that such liability may only be limited to the extent permitted by the GBCC. Under the GBCC, officers and directors will not be liable to the corporation or its shareholders for any action taken as a director, or any failure to take action, if they perform the duties of the office complying with the provisions of the GBCC. Directors and officers must perform their duties in good faith and with the degree of care an ordinary prudent person in a like position would exercise under similar circumstances. The business judgment rule generally precludes claims against directors and officers for actions amounting to ordinary negligence.

				Ann. Section 79-4-8.31 provides that a director is not liable to a corporation or its shareholders for any decision to take or not take action, or any failure to take any action, as a director, unless the party asserting liability proves certain matters. The party must show that (1) the director was a party to or had a direct or indirect financial interest in a transaction, which transaction was not otherwise approved in accordance with the MBCA, and (2) the challenged conduct consisted or was a result of (a) action not in good faith; (b) a decision which the director did not reasonably believe to be in the best interests of the corporation or as to which the director was not appropriately informed; (c) a lack of objectivity, due to familial, financial or business relationships, or a lack of independence, due to the director’s domination or control by another interested person, where such relationship, domination or control could reasonably be expected to have affected the director’s judgment respecting the challenged conduct in a manner adverse to the corporation, and after a reasonable expectation to such effect has been established, the director cannot demonstrate that he reasonably believed the challenged conduct to be in the best interests of the corporation; (d) the director’s sustained failure to stay informed about the corporation’s business and affairs or otherwise discharge his oversight functions; or (e) receipt of a financial benefit to which the director was not entitled or any other breach of the director’s duty to deal fairly with the corporation and its shareholders that is actionable under law.

TABLE OF CONTENTS

	Rights of First Bancshares Shareholders (which will be the rights of shareholders of the combined company following the merger)	Rights of SGB Shareholders
Dividends	The MBCA prohibits a Mississippi corporation from making any distributions to its shareholders, including the payment of cash dividends that would render the corporation unable to pay its debts as they become due in the usual course of business. Also prohibited is any distribution that would result in the corporation’s total assets being less than the sum of its total liabilities plus the amount that would be needed, if it were to be dissolved at the time of the distribution, to satisfy the preferential rights upon dissolution of shareholders whose preferential rights are superior to those receiving the distribution.	Under the SGB Bylaws, the board of directors may declare dividends on upon the capital stock of the corporation at any regular or special meeting. Dividends may be paid in cash, in property, or in shares of SGB’s capital stock. The GBCC prohibits a Georgia corporation from making any distribution to its shareholders if, after giving it effect: (i) the corporation would not be able to pay its debts as they become due in the usual course of business; or (ii) the corporation’s total assets would be less than the sum of its total liabilities plus the amount that would be needed, if the corporation were to be dissolved at the time of distribution, to satisfy the preferential rights upon dissolution of shareholders whose preferential rights are superior to those receiving the distribution.
Appraisal/Dissenters’ Rights	Under Section 79-4-13.02 of the MBCA, appraisal rights are available only in connection with specific transactions. However, appraisal rights are not available for shareholders if the shares are (i) listed on the New York Stock Exchange or designated as a national market system security on an interdealer quotation system by the National Association of Securities Dealers, Inc.; or (ii) not so listed or designated, but has at least 2,000 shareholders and the outstanding shares of such class or series has a market value of at least $20,000,000 (exclusive of the value of such shares held by its subsidiaries, senior executives, directors and beneficial shareholders owning more than 10% of such shares).	Under Section14-2-1302 of the GBCC, appraisal and dissenters’ rights are available for record shareholders only in connection with specific transactions. However, such rights are not available for shareholders if the shares are (i) listed on a national securities exchange, or (ii) held of record by more than 2,000 shareholders, unless the transaction meets certain requirements set out in the GBCC.

AGREEMENT AND PLAN OF MERGER

This Agreement and Plan of Merger (this “Agreement”) is dated as of December 18, 2019, by and between The First Bancshares, Inc., a Mississippi corporation (“FBMS”), and Southwest Georgia Financial Corporation, a Georgia corporation (“SWGB” and, together with FBMS, the “Parties” and each a “Party”).

W I T N E S S E T H

WHEREAS, the boards of directors of the Parties have determined that it is in the best interests of their respective companies and their respective shareholders to consummate the business combination transaction provided for in this Agreement in which SWGB will, on the terms and subject to the conditions set forth in this Agreement, merge with and into FBMS (the “Merger”), with FBMS as the surviving company in the Merger (sometimes referred to in such capacity as the “Surviving Entity”);

WHEREAS, as a condition to the willingness of FBMS to enter into this Agreement, certain directors of SWGB have entered into voting agreements (each a “SWGB Voting Agreement” and collectively, the “SWGB Voting Agreements”), substantially in the form attached hereto as Exhibit A, dated as of the date hereof, with FBMS, pursuant to which each such director has agreed, among other things, to vote certain of the SWGB Common Stock owned by such director in favor of the approval of this Agreement and the transactions contemplated hereby, subject to the terms of the SWGB Voting Agreements;

WHEREAS, the Parties desire to make certain representations, warranties and agreements in connection with the Merger and also to prescribe certain conditions to the Merger; and

WHEREAS, for U.S. federal income tax purposes, it is intended that the Merger qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”), and the Regulations promulgated thereunder, and this Agreement is intended to be and is adopted as a “plan of reorganization” for purposes of Sections 354 and 361 of the Code.

NOW, THEREFORE, in consideration of the mutual promises herein contained and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties agree as follows:

ARTICLE I

THE MERGER

Section 1.01 The Merger. Subject to the terms and conditions of this Agreement, in accordance with the Mississippi Business Corporation Act (the “MBCA”) and the Georgia Business Corporations Code (the “GBCC”), at the Effective Time, SWGB shall merge with and into FBMS pursuant to the terms of this Agreement. FBMS shall be the Surviving Entity in the Merger and shall continue its existence as a corporation under the laws of the State of Mississippi. As of the Effective Time, the separate corporate existence of SWGB shall cease.

Section 1.02 Articles of Incorporation and Bylaws. At the Effective Time, the articles of incorporation of FBMS in effect immediately prior to the Effective Time shall be the articles of incorporation of the Surviving Entity until thereafter amended in accordance with applicable Law. The bylaws of FBMS in effect immediately prior to the Effective Time shall be the bylaws of the Surviving Entity until thereafter amended in accordance with applicable Law and the terms of such bylaws.

Section 1.03 Bank Merger. Except as provided below, immediately following the Effective Time and sequentially but in effect simultaneously on the Closing Date, Southwest Georgia Bank, a Georgia state-chartered bank and a direct wholly owned subsidiary of SWGB (“Southwest Georgia Bank”), shall be merged (the “Bank Merger”) with and into The First, A National Banking Association, a national banking association and a direct wholly owned subsidiary of FBMS (“The First”), in accordance with the provisions of applicable federal banking laws and regulations, and The First shall be the surviving bank (the “Surviving Bank”).

TABLE OF CONTENTS

attached hereto as Exhibit B, and have caused the Bank Plan of Merger to be executed and delivered by The First and Southwest Georgia Bank simultaneously with the execution and delivery of this Agreement. As provided in the Bank Plan of Merger, the Bank Merger may be abandoned at the election of The First at any time, whether before or after filings are made for regulatory approval of the Bank Merger, but if the Bank Merger is abandoned for any reason, Southwest Georgia Bank shall continue to operate under its name; provided that prior to any such election, FBMS shall (a) reasonably consult with SWGB and its regulatory counsel and (b) reasonably determine in good faith that such election will not, and would not reasonably be expected to, prevent, delay or impair any Party’s ability to consummate the Merger or the other transactions contemplated by this Agreement.

MERGER CONSIDERATION; EXCHANGE PROCEDURES

Section 2.01 Merger Consideration. Subject to the provisions of this Agreement, at the Effective Time, automatically by virtue of the Merger and without any action on the part of the Parties or any shareholder of SWGB:

(a) Each share of FBMS Common Stock that is issued and outstanding immediately prior to the Effective Time shall remain outstanding following the Effective Time and shall be unchanged by the Merger.

(b) Each share of SWGB Common Stock owned directly by FBMS, SWGB or any of their respective Subsidiaries (other than shares in trust accounts, managed accounts and the like for the benefit of customers or shares held as collateral for outstanding debt previously contracted) immediately prior to the Effective Time shall be cancelled and retired at the Effective Time without any conversion thereof, and no payment shall be made with respect thereto (the “SWGB Cancelled Shares”).

(c) Notwithstanding anything in this Agreement to the contrary, all shares of SWGB Stock that are issued and outstanding immediately prior to the Effective Time and which are held by a shareholder who did not vote in favor of the Merger (or consent thereto in writing) and who is entitled to demand and properly demands the fair value of such shares pursuant to, and who complies in all respects with, the provisions of Title 14, Chapter 2, Article 13 of the GBCC, shall not be converted into or be exchangeable for the right to receive the Merger Consideration (the “Dissenting Shares”), but instead the holder of such Dissenting Shares (hereinafter called a “Dissenting Shareholder”) shall be entitled to payment of the fair value of such shares in accordance with the applicable provisions of the GBCC (and at the Effective Time, such Dissenting Shares shall no longer be outstanding and shall automatically be cancelled and shall cease to exist and such holder shall cease to have any rights with respect thereto, except the rights provided for pursuant to the applicable provisions of the GBCC and this Section 2.01(c)), unless and until such Dissenting Shareholder shall have failed to perfect such holder’s right to receive, or shall have effectively withdrawn or lost rights to demand or receive, the fair value of such shares of SWGB Stock under the applicable provisions of the GBCC. If any Dissenting Shareholder shall fail to perfect or effectively withdraw or lose such Holder’s dissenter’s rights under the applicable provisions of the GBCC, each such Dissenting Share shall be deemed to have been converted into and to have become exchangeable for, the right to receive the Merger Consideration, without any interest thereon, in accordance with the applicable provisions of this Agreement. SWGB shall give FBMS (i) prompt notice of any written notices to exercise dissenters’ rights in respect of any shares of SWGB Stock, attempted withdrawals of such notices and any other instruments served pursuant to the GBCC and received by SWGB relating to dissenters’ rights and (ii) the opportunity to participate in negotiations and proceedings with respect to demands for fair value under the GBCC. SWGB shall not, except with the prior written consent of FBMS, voluntarily make any payment with respect to, or settle, or offer or agree to settle, any such demand for payment. Any portion of the Merger Consideration made available to the Exchange Agent pursuant to this Article II to pay for shares of SWGB Stock for which dissenters’ rights have been perfected shall be returned to FBMS upon demand. If the amount paid to a Dissenting Shareholder exceeds such Dissenting Shareholder’s Merger Consideration, such excess amount shall not reduce the amount of Merger Consideration paid to other Holders.

(d) Each share of SWGB Common Stock (excluding Dissenting Shares and SWGB Cancelled Shares) issued and outstanding at the Effective Time shall cease to be outstanding and shall be converted, in accordance with the terms of this Article II, into and exchanged for the right to receive one (1.00) share of FBMS Common Stock (the “Merger Consideration”).

Section 2.02 SWGB Stock-Based Awards.

(a) At the Effective Time, each outstanding restricted stock award granted under the SWGB Stock Plans (a “SWGB Restricted Share”) shall, automatically and without any required action on the part of the holder thereof, cease to represent a restricted share of SWGB Common Stock and shall be converted into a number of restricted shares of FBMS Common Stock (each, a “Converted Restricted Share”) equal to the product (with the result rounded down to the nearest whole number) of (i) the number of SWGB Restricted Shares subject to such award multiplied by (ii) one (1.00). Except as specifically provided above, following the Effective Time, each such Converted Restricted Share shall continue to be governed by the same terms and conditions (including vesting and forfeiture terms) as were applicable to the corresponding SWGB Restricted Share immediately prior to the Effective Time, except that each Converted Restricted Share shall be amended to provide for vesting in full, to the extent not vested previously, if the holder’s employment with FBMS (or any of its Subsidiaries) is terminated within one year following the Effective Time (other than for cause, death, disability, normal retirement or voluntary resignation).

(b) Prior to the Effective Time, SWGB, the board of directors of SWGB and the compensation committee of the board of directors of SWGB, as applicable, shall adopt any resolutions and take any actions that are necessary to effectuate the treatment of the SWGB Restricted Shares pursuant to Section 2.02(a). SWGB shall take all actions necessary to ensure that, from and after the Effective Time, neither FBMS nor any of its subsidiaries will be required to deliver shares of SWGB Common Stock or other capital stock of SWGB to any person pursuant to or in settlement of the SWGB Restricted Shares.

(c) FBMS shall take all actions that are necessary for the treatment of the SWGB Restricted Shares pursuant to Section 2.02(a), including the reservation, issuance, securities registration (including on the Registration Statement or a registration statement on Form S-8) and listing of FBMS Common Stock as necessary to effect the transactions contemplated by this Section 2.02.

Section 2.03 Rights as Shareholders; Stock Transfers. At the Effective Time, all shares of SWGB Common Stock, when converted in accordance with Section 2.01, shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist, and each Certificate or Book-Entry Share previously evidencing such shares shall thereafter represent only the right to receive for each such share of SWGB Common Stock, the Merger Consideration and any cash in lieu of fractional shares of FBMS Common Stock in accordance with this Article II. At the Effective Time, holders of SWGB Common Stock shall cease to be, and shall have no rights as, shareholders of SWGB, other than the right to receive the Merger Consideration and cash in lieu of fractional shares of FBMS Common Stock as provided under this Article II. At the Effective Time, the stock transfer books of SWGB shall be closed, and there shall be no registration of transfers on the stock transfer books of SWGB of shares of SWGB Common Stock.

Section 2.04 Fractional Shares. Notwithstanding any other provision hereof, no fractional shares of FBMS Common Stock and no certificates or scrip therefor, or other evidence of ownership thereof, will be issued in the Merger. In lieu thereof, FBMS shall pay or cause to be paid to each Holder of a fractional share of FBMS Common Stock, rounded to the nearest one hundredth of a share, an amount of cash (without interest and rounded to the nearest whole cent) determined by multiplying the fractional share interest in FBMS Common Stock to which such Holder would otherwise be entitled by the FBMS Average Stock Price.

Section 2.05 Plan of Reorganization. It is intended that the Merger shall qualify as a “reorganization” within the meaning of Section 368(a) of the Code, and that this Agreement shall constitute a “plan of reorganization” as that term is used in Sections 354 and 361 of the Code.

Section 2.06 Exchange Procedures. FBMS shall cause as promptly as practicable after the Effective Time, but in no event later than five (5) Business Days after the Closing Date, the Exchange Agent to mail or otherwise cause to be delivered to each Holder, appropriate and customary transmittal materials in form and substance mutually agreed upon by the Parties, which shall specify that delivery shall be effected, and risk of loss and title to the Certificates or Book-Entry Shares shall pass, only upon delivery of the Certificates or Book-Entry Shares to the Exchange Agent, as well as instructions for use in effecting the surrender of the Certificates or Book-Entry Shares in exchange for the Merger Consideration (including cash in lieu of fractional shares) as provided for in this Agreement (the “Letter of Transmittal”).

TABLE OF CONTENTS

Section 2.07 Deposit and Delivery of Merger Consideration.

(a) Prior to the Effective Time, FBMS shall (i) deposit, or shall cause to be deposited, with the Exchange Agent stock certificates representing the number of shares of FBMS Common Stock to deliver the Merger Consideration (together with, to the extent then determinable, any cash payable in lieu of fractional shares pursuant to Section 2.04, and if applicable, cash in an aggregate amount sufficient to make the appropriate payment to the Holders of Dissenting Shares) (collectively, the “Exchange Fund”), and (ii) instruct the Exchange Agent to pay such Merger Consideration and cash in lieu of fractional shares in accordance with this Agreement as promptly as practicable after the Effective Time and conditioned upon receipt of a properly completed Letter of Transmittal. The Exchange Agent and FBMS, as the case may be, shall not be obligated to deliver the Merger Consideration to a Holder to which such Holder would otherwise be entitled as a result of the Merger until such Holder surrenders the Certificates or Book-Entry Shares representing the shares of SWGB Common Stock for exchange as provided in this Article II, or an appropriate affidavit of loss and indemnity agreement and/or a bond in such amount as may be reasonably required in each case by FBMS or the Exchange Agent.

(b) Any portion of the Exchange Fund that remains unclaimed by the shareholders of SWGB for one (1) year after the Effective Time (as well as any interest or proceeds from any investment thereof) shall be delivered by the Exchange Agent to FBMS. Any shareholders of SWGB who have not theretofore complied with this Section 2.07 shall thereafter look only to FBMS for the Merger Consideration, any cash in lieu of fractional shares of SWGB Common Stock to be issued or paid in consideration therefor, and any dividends or distributions to which such Holder is entitled in respect of each share of SWGB Common Stock such shareholder held immediately prior to the Effective Time, as determined pursuant to this Agreement, in each case without any interest thereon. If outstanding Certificates or Book-Entry Shares for shares of SWGB Common Stock are not surrendered or the payment for them is not claimed prior to the date on which such shares of FBMS Common Stock or cash would otherwise escheat to or become the property of any governmental unit or agency, the unclaimed items shall, to the extent permitted by the law of abandoned property and any other applicable Law, become the property of FBMS (and to the extent not in its possession shall be delivered to it), free and clear of all claims or interest of any Person previously entitled to such property. Neither the Exchange Agent nor any Party shall be liable to any Holder represented by any Certificate or Book-Entry Share for any amounts delivered to a public official pursuant to applicable abandoned property, escheat or similar Laws. FBMS and the Exchange Agent shall be entitled to rely upon the stock transfer books of SWGB to establish the identity of those Persons entitled to receive the Merger Consideration specified in this Agreement, which books shall be conclusive with respect thereto. In the event of a dispute with respect to ownership of any shares of SWGB Common Stock represented by any Certificate or Book-Entry Share, FBMS and the Exchange Agent shall be entitled to tender to the custody of any court of competent jurisdiction any Merger Consideration represented by such Certificate or Book-Entry Share and file legal proceedings interpleading all parties to such dispute, and will thereafter be relieved with respect to any claims thereto.

(c) FBMS or the Exchange Agent, as applicable, shall be entitled to deduct and withhold from any amounts otherwise payable pursuant to this Agreement to any Holder such amounts as FBMS is required to deduct and withhold under applicable Law. Any amounts so deducted and withheld shall be remitted to the appropriate Governmental Authority and upon such remittance shall be treated for all purposes of this Agreement as having been paid to the Holder in respect of which such deduction and withholding was made by FBMS or the Exchange Agent, as applicable.

Section 2.08 Rights of Certificate Holders after the Effective Time.

(a) All shares of FBMS Common Stock to be issued pursuant to the Merger shall be deemed issued and outstanding as of the Effective Time and if ever a dividend or other distribution is declared by FBMS in respect of the FBMS Common Stock, the record date for which is at or after the Effective Time, that declaration shall include dividends or other distributions in respect of all shares of FBMS Common Stock issuable pursuant to this Agreement. No dividends or other distributions in respect of the FBMS Common Stock shall be paid to any Holder of any unsurrendered Certificate or

A-5

TABLE OF CONTENTS

Book-Entry Share until such Certificate or Book-Entry Share is surrendered for exchange in accordance with this Article II. Subject to the effect of applicable Laws, following surrender of any such Certificate or Book-Entry Share, there shall be issued and/or paid to the Holder of the certificates representing whole shares of FBMS Common Stock issued in exchange therefor, without interest, (i) at the time of such surrender, the dividends or other distributions with a record date after the Effective Time theretofore payable with respect to such whole shares of FBMS Common Stock and not paid and (ii) at the appropriate payment date, the dividends or other distributions payable with respect to such whole shares of FBMS Common Stock with a record date after the Effective Time but with a payment date subsequent to surrender.

(b) In the event of a transfer of ownership of a Certificate representing SWGB Common Stock that is not registered in the stock transfer records of SWGB, the proper amount of shares of FBMS Common Stock shall be issued in exchange therefor to a person other than the person in whose name the Certificate so surrendered is registered if the Certificate formerly representing such SWGB Common Stock shall be properly endorsed or otherwise be in proper form for transfer and the person requesting such issuance shall pay any transfer or other similar Taxes required by reason of the issuance to a person other than the registered Holder of the Certificate or establish to the satisfaction of FBMS or the Exchange Agent that the Tax has been paid or is not applicable.

Section 2.09 Anti-Dilution Provisions. If the number of shares of FBMS Common Stock or SWGB Common Stock issued and outstanding prior to the Effective Time shall be increased or decreased, or changed into or exchanged for a different number of kind of shares or securities, in any such case as a result of a stock split, reverse stock split, stock combination, stock dividend, recapitalization, reclassification, reorganization or similar transaction, or there shall be any extraordinary dividend or distribution with respect to such stock, and the record date therefor shall be prior to the Effective Time, an appropriate and proportionate adjustment shall be made to the Merger Consideration to give holders of SWGB Common Stock the same economic effect as contemplated by this Agreement prior to such event.

(b) Except to the extent SWGB has made an SWGB Subsequent Determination in accordance with Section 5.09, (i) the board of directors of SWGB shall at all times prior to and during the SWGB Meeting recommend approval of this Agreement by the shareholders of SWGB and any other matters required to be approved by SWGB’s shareholders for consummation of the Merger and the transactions contemplated hereby (the “SWGB Recommendation”) and (ii) shall not withhold, withdraw, amend, modify, change or qualify such recommendation in a manner adverse in any respect to the interests of FBMS or take any other action or make any other public statement inconsistent with such recommendation and the Proxy Statement-Prospectus shall include the SWGB Recommendation. In the event that there is present at such meeting, in person or by proxy, sufficient favorable voting power to secure the Requisite SWGB Shareholder Approval, SWGB will not adjourn or postpone the SWGB Meeting unless SWGB is advised by counsel that failure to do so would reasonably be expected to result in a breach of the fiduciary duties of the board of directors of SWGB. SWGB shall keep FBMS updated with respect to the proxy solicitation results in connection with the SWGB Meeting as reasonably requested by FBMS.

Section 5.05 Registration Statement; Proxy Statement-Prospectus; NASDAQ Listing.

(a) FBMS and SWGB agree to cooperate in the preparation of the Registration Statement to be filed by FBMS with the SEC in connection with the issuance of FBMS Common Stock in the transactions contemplated by this Agreement (including the Proxy Statement-Prospectus and all related documents). SWGB shall use its reasonable best efforts to deliver to FBMS such financial statements and related analysis of SWGB, including “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of SWGB, as may be required in order to file the Registration Statement, and any other report required to be filed by FBMS with the SEC, in each case, in compliance in all material respects with applicable Laws, and shall, as promptly as practicable following execution of this Agreement, prepare and deliver drafts of such information to FBMS to review. Within forty-five (45) days of the date of this Agreement, FBMS shall file with the SEC the

Registration Statement. Each of FBMS and SWGB agree to use their respective commercially reasonable efforts to cause the Registration Statement to be declared effective by the SEC as promptly as reasonably practicable after the filing thereof and to maintain such effectiveness for as long as necessary to consummate the Merger and the other transactions contemplated by this Agreement. FBMS also agrees to use commercially reasonable efforts to obtain any necessary state securities Law or “blue sky” permits and approvals required to carry out the transactions contemplated by this Agreement. SWGB agrees to cooperate with FBMS and FBMS’s counsel and accountants in requesting and obtaining appropriate opinions, consents and letters from SWGB’s independent auditors in connection with the Registration Statement and the Proxy Statement-Prospectus.

(b) FBMS will advise SWGB, promptly after FBMS receives notice thereof, of the time when the Registration Statement has become effective or any supplement or amendment has been filed, of the issuance of any stop order or the suspension of the qualification of FBMS Common Stock for offering or sale in any jurisdiction, of the initiation or threat of any proceeding for any such purpose, or of any request by the SEC for the amendment or supplement of the Registration Statement or upon the receipt of any comments (whether written or oral) from the SEC or its staff. FBMS will provide SWGB and its counsel with a reasonable opportunity to review and comment on the Registration Statement and the Proxy Statement-Prospectus, and all responses to requests for additional information by and replies to comments of the SEC prior to filing such with, or sending such to, the SEC, and FBMS will provide SWGB and its counsel with a copy of all such filings made with the SEC. If at any time prior to the Effective Time there shall occur any event that should be disclosed in an amendment or supplement to the Proxy Statement-Prospectus or the Registration Statement so that either such document would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, FBMS shall use its commercially reasonable efforts to promptly prepare and file such amendment or supplement with the SEC (if required under applicable Law) and cooperate with SWGB to mail such amendment or supplement to SWGB shareholders (if required under applicable Law).

(c) FBMS will use its commercially reasonable efforts to cause the shares of FBMS Common Stock to be issued in connection with the transactions contemplated by this Agreement to be approved for listing on NASDAQ, subject to official notice of issuance, prior to the Effective Time.

Section 5.06 Regulatory Filings; Consents.

(a) Each of FBMS and SWGB and their respective Subsidiaries shall cooperate and use their respective reasonable best efforts (i) to promptly prepare all documentation (including the Registration Statement and the Proxy Statement-Prospectus), and to effect all filings, to obtain all permits, consents, approvals and authorizations of all third parties and Governmental Authorities necessary to consummate the transactions contemplated by this Agreement, the Regulatory Approvals and all other consents and approvals of a Governmental Authority required to consummate the Merger in the manner contemplated herein, (ii) to comply with the terms and conditions of such permits, consents, approvals and authorizations and (iii) to cause the transactions contemplated by this Agreement to be consummated as expeditiously as practicable; provided, however, notwithstanding the foregoing or anything to the contrary in this Agreement, nothing contained herein shall be deemed to require FBMS or any of its Subsidiaries or SWGB or any of its Subsidiaries to take any non-standard action, or commit to take any such action, or agree to any non-standard condition or restriction, in connection with obtaining the foregoing permits, consents, approvals and authorizations of any Governmental Authority that would reasonably be likely to have a material and adverse effect (measured on a scale relative to the affected Party) on the condition (financial or otherwise), results of operations, liquidity, assets or deposit liabilities, properties or business of FBMS, SWGB, the Surviving Entity or the Surviving Bank, after giving effect to the Merger (“Burdensome Condition”). FBMS and SWGB will furnish each other and each other’s counsel with all information concerning themselves, their Subsidiaries, directors, trustees, officers and shareholders and such other matters as may be necessary or advisable in connection with any application, petition or any other statement or application made by or on behalf of FBMS or SWGB to any Governmental Authority in connection with the

transactions contemplated by this Agreement.

The Parties and their representatives will consult as often as practicable under the circumstances so as to permit SWGB and FBMS and their respective representatives to cooperate to take appropriate measures to obtain such consents and avoid or mitigate any adverse consequences that may result from the foregoing.

Section 5.07 Publicity. FBMS and SWGB shall consult with each other before issuing any press release with respect to this Agreement or the transactions contemplated hereby and shall not issue any such press release or make any such public statement without the prior consent of the other Party, which shall not be unreasonably delayed or withheld; provided, however, that a party may, without the prior consent of the other party (but after such consultation, to the extent practicable in the circumstances), issue such press release or make such public statements as may upon the advice of counsel be required by Law or the rules and regulations of any stock exchanges. It is understood that FBMS shall assume primary responsibility for the preparation of joint press releases relating to this Agreement, the Merger and the other transactions contemplated hereby.

(e) No investigation by a Party or its representatives shall be deemed to modify or waive any representation, warranty, covenant or agreement of the other Party set forth in this Agreement, or the conditions to the respective obligations of FBMS and SWGB to consummate the transactions contemplated hereby.

(f) Notwithstanding anything to the contrary in this Section 5.08, SWGB shall not be required to copy FBMS on any documents that disclose confidential discussions of this Agreement or the transactions contemplated hereby, that contain competitively sensitive business or other proprietary or confidential information filed under a claim of confidentiality (including any confidential supervisory information) or any other matter that SWGB’s board of directors has been advised by counsel that such distribution to FBMS may violate a confidentiality obligation or fiduciary duty or any Law or regulation, or may result in a waiver of SWGB’s attorney-client privilege. In the event any of the restrictions in this Section 5.08(f) shall apply, SWGB shall use its commercially reasonable efforts to provide summary disclosure of such matters or other appropriate alternate disclosure arrangements, including adopting additional specific procedures to protect the confidentiality of sensitive material and to ensure compliance with applicable Laws.

(a) Except as permitted by Section 5.09(b), SWGB shall not, and shall cause its Subsidiaries and each of their respective officers, directors and employees not to, and will not authorize any investment bankers, financial advisors, attorneys, accountants, consultants, affiliates or other agents of SWGB or any of SWGB’s Subsidiaries (collectively, the “SWGB Representatives”) to, directly or indirectly, (i) initiate, solicit, induce or knowingly encourage, or take any action to facilitate the making of, any inquiry, offer or proposal which constitutes, or could reasonably be expected to lead to, an Acquisition Proposal; (ii) participate in any discussions or negotiations regarding any Acquisition Proposal or furnish, or otherwise afford access, to any Person (other than FBMS) any information or data with respect to SWGB or any of its Subsidiaries in connection with a potential Acquisition Proposal; (iii) release any Person from, waive any provisions of, or fail to enforce any confidentiality agreement or standstill agreement to which SWGB is a party; or (iv) enter into any agreement, confidentiality agreement, agreement in principle or letter of intent with respect to any Acquisition Proposal or approve or resolve to approve any Acquisition Proposal or any agreement, agreement in principle or letter of intent relating to an Acquisition Proposal. Any violation of the foregoing restrictions by any of the SWGB Representatives, whether or not such SWGB Representative is so authorized and whether or not such SWGB Representative is purporting to act on behalf of SWGB or otherwise, shall be deemed to be a breach of this Agreement by SWGB. SWGB and its Subsidiaries shall, and shall cause each of the SWGB Representatives to, immediately cease and cause to be terminated any and all existing discussions, negotiations, and communications with any Persons with respect to any existing or potential Acquisition Proposal.

For purposes of this Agreement, “Acquisition Proposal” means any inquiry, offer or proposal (other than an inquiry, offer or proposal from FBMS), whether or not in writing, contemplating, relating to, or that could reasonably be expected to lead to, an Acquisition Transaction.

A-35

TABLE OF CONTENTS

For purposes of this Agreement, “Acquisition Transaction” means (A) any transaction or series of transactions involving any merger, consolidation, recapitalization, share exchange, liquidation, dissolution or similar transaction involving SWGB or any of its Subsidiaries; (B) any transaction pursuant to which any third party or group acquires or would acquire (whether through sale, lease or other disposition), directly or indirectly, the assets of SWGB or any of its Subsidiaries constituting, in the aggregate, twenty percent (20%) or more of the fair value of the consolidated assets of SWGB; (C) any issuance, sale or other disposition of (including by way of merger, consolidation, share exchange or any similar transaction) securities (or options, rights or warrants to purchase or securities convertible into, such securities) representing twenty percent (20%) or more of the votes attached to the outstanding securities of SWGB or any of its Subsidiaries; (D) any tender offer or exchange offer that, if consummated, would result in any third party or group beneficially owning twenty percent (20%) or more of any class of equity securities of SWGB or any of its Subsidiaries; or (E) any transaction which is similar in form, substance or purpose to any of the foregoing transactions, or any combination of the foregoing.

For purposes of this Agreement, “Superior Proposal” means a bona fide, unsolicited Acquisition Proposal (i) that if consummated would result in a third party (or in the case of a direct merger between such third party and SWGB or any of its Subsidiaries, the shareholders of such third party) acquiring, directly or indirectly, more than fifty percent (50%) of the outstanding SWGB Common Stock or more than fifty percent (50%) of the assets of SWGB and its Subsidiaries (measured as a percentage of the fair value of the consolidated assets of SWGB), taken as a whole, for consideration consisting of cash and/or securities and (ii) that the board of directors of SWGB reasonably determines in good faith, after consultation with its outside financial advisor and outside legal counsel, (A) is reasonably capable of being completed, taking into account all financial, legal, regulatory and other aspects of such proposal, including all conditions contained therein and the person making such Acquisition Proposal, and (B) taking into account any changes to this Agreement proposed by FBMS in response to such Acquisition Proposal, as contemplated by Section 5.09(d), and all financial, legal, regulatory and other aspects of such takeover proposal, including all conditions contained therein and the person making such proposal, is more favorable to the shareholders of SWGB from a financial point of view than the Merger.

(b) Notwithstanding Section 5.09(a) or any other provision of this Agreement, prior to the date of the SWGB Meeting, SWGB may take any of the actions described in Section 5.09(a) if, but only if, (i) SWGB has received a bona fide unsolicited written Acquisition Proposal that did not result from a breach of Section 5.09(a); (ii) the board of directors of SWGB reasonably determines in good faith, after consultation with and having considered the advice of its outside financial advisor and outside legal counsel, that (A) such Acquisition Proposal constitutes or is reasonably likely to lead to a Superior Proposal and (B) the failure to take such actions would reasonably be expected to cause it to breach its fiduciary duties under applicable Law; (iii) SWGB has provided FBMS with at least three (3) Business Days’ prior notice of such determination, and (iv) prior to furnishing or affording access to any information or data with respect to SWGB or any of its Subsidiaries or otherwise relating to an Acquisition Proposal, SWGB receives from such Person a confidentiality agreement with terms no less favorable to SWGB than those contained in the confidentiality agreement with FBMS. SWGB shall promptly provide to FBMS any non-public information regarding SWGB or its Subsidiaries provided to any other Person which was not previously provided to FBMS, such additional information to be provided no later than the date of provision of such information to such other party.

(c) SWGB shall promptly (and in any event within twenty-four (24) hours) notify FBMS in writing if any proposals or offers are received by, any information is requested from, or any negotiations or discussions are sought to be initiated or continued with, SWGB or the SWGB Representatives, in each case in connection with any Acquisition Proposal, and such notice shall indicate the name of the Person initiating such discussions or negotiations or making such proposal, offer or information request and the material terms and conditions of any proposals or offers (and, in the case of written materials relating to such proposal, offer, information request, negotiations or discussion, providing copies of such materials (including e-mails or other electronic communications) except to the extent that such materials constitute confidential information of the party making such offer or proposal under an effective confidentiality agreement). SWGB agrees that it shall keep FBMS

A-36

TABLE OF CONTENTS

informed, on a reasonably current basis, of the status and terms of any such proposal, offer, information request, negotiations or discussions (including any amendments or modifications to such proposal, offer or request).

Except as provided in Section 5.09(e), neither the board of directors of SWGB nor the board of directors of any Subsidiary nor any committee of any boards of directors of SWGB or its Subsidiaries shall (i) fail to make or withdraw (or modify or qualify in any manner adverse to FBMS or publicly propose to withdraw, modify, or qualify in any manner adverse to FBMS) the SWGB Recommendation, or the determination of the advisability to its shareholders of the approval of this Agreement and the transactions contemplated hereby, including the Merger, (ii) adopt, approve, or publicly recommend, endorse or otherwise declare advisable any Acquisition Proposal, (iii) fail to include the SWGB Recommendation in whole or in part in the Proxy Statement Prospectus or any filing or amendment or supplement relating thereto, (iv) fail to recommend against any then-pending tender or exchange offer that constitutes an Acquisition Proposal within five (5) Business Days after it is announced, (v) fail to reaffirm the SWGB Recommendation within three (3) Business Days following a request by FBMS, or make any statement, filing or release, in connection with the SWGB Meeting or otherwise, inconsistent with the SWGB Recommendation, or (vi) resolve to do any of the foregoing. Each such action set forth in this Section 5.09(d) shall be referred to herein as an “Adverse Recommendation Action.”

(d) Notwithstanding Section 5.09(c), prior to the receipt of the Requisite SWGB Shareholder Approval, the board of directors of SWGB may withdraw, qualify, amend or modify the SWGB Recommendation (a “SWGB Subsequent Determination”) or cause or permit SWGB to terminate this Agreement to enter into a definitive agreement with respect to such Superior Proposal in accordance with the terms of Section 7.01(g) after the fifth (5th) Business Day following FBMS’s receipt of a notice (the “Notice of Superior Proposal”) from SWGB advising FBMS that the board of directors of SWGB has decided (in good faith after consultation with its outside legal counsel and financial advisor) that a bona fide unsolicited written Acquisition Proposal that it received (that did not result from a breach of Section 5.09(a)) constitutes a Superior Proposal if, but only if, (i) the board of directors of SWGB has determined in good faith, after consultation with and having considered the advice of outside legal counsel and its financial advisor, that the failure to take such actions would reasonably be expected to cause it to violate its fiduciary duties to SWGB’s shareholders under applicable Law, (ii) during the five (5) Business Day period after receipt of the Notice of Superior Proposal by FBMS (the “Notice Period”), SWGB and the board of directors of SWGB shall have cooperated and negotiated in good faith with FBMS to make such adjustments, modifications or amendments to the terms and conditions of this Agreement as would enable SWGB to proceed with the SWGB Recommendation without a SWGB Subsequent Determination; provided, however, that FBMS shall not have any obligation to propose any adjustments, modifications or amendments to the terms and conditions of this Agreement and (iii) at the end of the Notice Period, after taking into account any such adjusted, modified, or amended terms as may have been proposed by FBMS since its receipt of such Notice of Superior Proposal, the board of directors of SWGB has again in good faith made the determination (A) in clause (i) of this Section 5.09(d) and (B) that such Acquisition Proposal constitutes a Superior Proposal. In the event of any material revisions to the Superior Proposal, SWGB shall be required to deliver a new Notice of Superior Proposal to FBMS and again comply with the requirements of this Section 5.09(d), except that the Notice Period shall be reduced to three (3) Business Days.

(e) Notwithstanding any SWGB Subsequent Determination, this Agreement shall be submitted to SWGB’s shareholders at the SWGB Meeting for the purpose of voting on the approval of this Agreement and the transactions contemplated hereby (including the Merger) and nothing contained herein shall be deemed to relieve SWGB of such obligation; provided, however, that if the board of directors of SWGB shall have made a SWGB Subsequent Determination with respect to a Superior Proposal, then the board of directors of SWGB may recommend approval of such Superior Proposal by the shareholders of SWGB and may submit this Agreement to SWGB’s shareholders without recommendation, in which event the board of directors of SWGB shall communicate the basis for its recommendation of such Superior Proposal and the basis for its lack of a recommendation with respect to this Agreement and the transactions contemplated hereby to SWGB’s shareholders in the Proxy Statement-Prospectus or an appropriate amendment or supplement thereto.

TABLE OF CONTENTS

(f) Nothing contained in this Section 5.09 shall prohibit SWGB or the board of directors of SWGB from complying with SWGB’s obligations required under Rule 14e-2(a) promulgated under the Exchange Act; provided, however, that any such disclosure relating to an Acquisition Proposal (other than a “stop, look and listen” or similar communication of the type contemplated by Rule 14d-9(f) under the Exchange Act) shall be deemed a change in the SWGB Recommendation unless the board of directors of SWGB reaffirms the SWGB Recommendation in such disclosure.

Section 5.10 Indemnification.

(a) For a period of six (6) years from and after the Effective Time, and in any event subject to the provisions of Section 5.10(c)(iv), FBMS shall indemnify and hold harmless the present and former directors and officers of SWGB and its Subsidiaries (each an “Indemnified Party”), against all costs, expenses (including reasonable attorney’s fees), judgments, fines, losses, claims, damages or liabilities or amounts that are paid in settlement (which settlement shall require the prior written consent of FBMS, which consent shall not be unreasonably withheld, delayed, or conditioned) of or in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative (each a “Claim”), arising out of actions or omissions of such persons in the course of performing their duties for SWGB or any of its Subsidiaries occurring at or before the Effective Time (including the Merger and the other transactions contemplated hereby), regardless of whether such Claim is asserted or claimed before, or after, the Effective Time, to the same extent required or permitted under the organizational documents of SWGB and its Subsidiaries in effect on the date of this Agreement, in each case to the extent permitted by applicable Law.

(b) In connection with the indemnification provided pursuant to Section 5.10, FBMS and/or an FBMS Subsidiary will advance expenses, promptly after statements therefor are received, to each SWGB Indemnified Party, to the same extent permitted under the organizational documents of SWGB and its Subsidiaries in effect on the date of this Agreement, in each case to the extent permitted by applicable Law (provided the individual to whom expenses are advanced provides an undertaking to repay such advance if it is ultimately determined that such individual is not entitled to indemnification), including the payment of the fees and expenses of one counsel with respect to a matter, and one local counsel in each applicable jurisdiction, if necessary or appropriate, selected by such SWGB Indemnified Party or multiple Indemnified Parties, it being understood that they collectively shall only be entitled to one counsel and one local counsel in each applicable jurisdiction where necessary or appropriate (unless a conflict shall exist between them in which case they may retain separate counsel).

(c) Any Indemnified Party wishing to claim indemnification under this Section 5.10 shall promptly notify FBMS upon learning of any Claim, provided that, failure to so notify shall not affect the obligation of FBMS under this Section 5.10, unless, and only to the extent that, FBMS is materially prejudiced in the defense of such Claim as a consequence. In the event of any such Claim (whether asserted or claimed prior to, at or after the Effective Time), (i) FBMS shall have the right to assume the defense thereof and FBMS shall not be liable to such Indemnified Parties for any legal expenses or other counsel or any other expenses subsequently incurred by such Indemnified Parties in connection with the defense thereof, (ii) the Indemnified Parties will cooperate in the defense of any such matter, (iii) FBMS shall not be liable for any settlement effected without its prior written consent (which shall not be unreasonably withheld, delayed, or conditioned) and (iv) FBMS shall have no obligation hereunder to any Indemnified Party if such indemnification would be in violation of any applicable federal or state banking Laws or regulations, or in the event that a federal or state banking agency or a court of competent jurisdiction shall determine that indemnification of an Indemnified Party in the manner contemplated hereby is prohibited by applicable Laws and regulations, whether or not related to banking Laws.

(d) For a period of six (6) years following the Effective Time, FBMS will maintain director’s and officer’s liability insurance (herein, “D&O Insurance”) that serves to reimburse the present and former officers and directors of SWGB or its Subsidiaries (determined as of the Effective Time) with respect to claims against such directors and officers arising from facts or events occurring at or before the Effective Time (including the transactions contemplated hereby), which insurance will contain at least

A-38

TABLE OF CONTENTS

the same coverage and amounts, and contain terms and conditions no less advantageous to the Indemnified Party, as that coverage currently provided by SWGB; provided that, if FBMS is unable to maintain or obtain the insurance called for by this Section 5.10, FBMS will provide as much comparable insurance as is reasonably available (subject to the limitations described below in this Section 5.10(d)); and provided, further, that officers and directors of SWGB or its Subsidiaries may be required to make application and provide customary representations and warranties to the carrier of the D&O Insurance for the purpose of obtaining such insurance. In no event shall FBMS be required to expend for such tail insurance a premium amount in excess of an amount equal to two hundred percent (200%) of the annual premiums paid by SWGB for D&O Insurance in effect as of the date of this Agreement (the “Maximum D&O Tail Premium”). If the cost of such tail insurance exceeds the Maximum D&O Tail Premium, FBMS shall obtain tail insurance coverage or a separate tail insurance policy with the greatest coverage available for a cost not exceeding the Maximum D&O Tail Premium.

(e) This Section 5.10 shall survive the Effective Time, is intended to benefit each SWGB Indemnified Party (each of whom shall be entitled to enforce this Section against FBMS), and shall be binding on all successors and assigns of FBMS.

(f) If FBMS or any of its successors and assigns (i) shall consolidate with or merge into any other corporation or entity and shall not be the continuing or surviving corporation or entity of such consolidation or merger, or (ii) shall transfer all or substantially all of its property and assets to any individual, corporation or other entity, then, in each such case, proper provision shall be made so that the successors and assigns of FBMS and its Subsidiaries shall assume the obligations set forth in this Section 5.10.

Section 5.11 Employees; Benefit Plans.

(a) Following the Effective Time, FBMS shall maintain or cause to be maintained employee benefit plans for the benefit of employees who are employees of SWGB on the Closing Date and who become employees of FBMS as of the Effective Time (“Covered Employees”) that provide employee benefits which, in the aggregate, are substantially comparable to the employee benefits and compensation opportunities, including participation in employee stock ownership plans and retirement plans, that are made available on a uniform and non-discriminatory basis to similarly situated employees of FBMS; provided, however, that in no event shall any Covered Employee be eligible to participate in any closed or frozen plan of FBMS. FBMS shall give the Covered Employees credit for their prior service with SWGB (i) for purposes of eligibility (including initial participation and eligibility for current benefits) and vesting under any qualified or non-qualified employee benefit plan maintained by FBMS and in which Covered Employees may be eligible to participate and (ii) for all purposes under any welfare benefit plans, vacation plans (although FBMS may consider current vacation benefits provided to such employees by SWGB), severance plans and similar arrangements maintained by FBMS.

(b) With respect to any employee benefit plan of FBMS that is a health, dental, vision or other welfare plan in which any Covered Employee is eligible to participate, for the plan year in which such Covered Employee is first eligible to participate, FBMS shall use its commercially reasonable efforts to (i) cause any pre-existing condition limitations, eligibility waiting periods or evidence of insurability requirements under such FBMS plan to be waived with respect to such Covered Employee and his or her covered dependents to the extent such condition was or would have been covered under the SWGB Benefit Plan in which such Covered Employee participated immediately prior to the Effective Time and (ii) give each Covered Employee credit towards applicable co-payments, deductibles and annual out-of-pocket limits for expenses incurred prior to the Effective Time for which payment has been made (taking into account any differences in plan years and applicable rules and regulations related to such differences in plan years).

(c) Following the Effective Time, The First shall credit each Covered Employee with an amount of paid time off equal to such Covered Employee’s accrued but unused paid time off at Southwest Georgia Bank as of the Effective Time (“Carryover PTO”), provided that The First may allocate the Carryover PTO and between vacation leave and sick leave in its discretion.

(d) SWGB shall cause Southwest Georgia Bank to take all necessary actions to terminate its participation in the Southwest Georgia Bank 401(k) Plan, effective as the date immediately preceding the Effective Time of the Merger, subject to the occurrence of the Effective Time. SWGB shall provide FBMS with evidence that the such participation has been terminated and provide copies of the appropriate resolutions terminating participation (the form and substance of which shall be subject to review and approval by FBMS, which will not be unreasonably withheld) not later than the day immediately preceding the Effective Time. The accounts of all participants and beneficiaries in the Southwest Georgia Bank 401(k) Plan shall become fully vested upon termination of participation in such plan.

(e) Prior to the Effective Time, SWGB shall take, and shall cause its Subsidiaries to take, all actions reasonably requested by FBMS that may be necessary or appropriate to, conditioned on the occurrence of the Effective Time, (i) cause one or more SWGB Benefits Plans not covered above to terminate as of the Effective Time, or as of the date immediately preceding the Effective Time, (ii) cause benefit accruals and entitlements under any SWGB Benefit Plan to cease as of the Effective Time, or as of the date immediately preceding the Effective Time, (iii) cause the continuation on and after the Effective Time of any contract, arrangement or insurance policy relating to any SWGB Benefit Plan for such period as may be reasonably requested by FBMS, or (iv) facilitate the merger of any SWGB Benefit Plan into any employee benefit plan maintained by FBMS. Additionally, SWGB and Southwest Georgia Bank will take any and all actions reasonably requested by FBMS related to ensuring the compliance of all SWGB Benefit Plans with applicable law, including filing any necessary “top hat” filings or corrections.

A-45

TABLE OF CONTENTS

by the earlier of the (i) two (2) Business Days prior to the Termination Date or (ii) thirty (30) days following written notice to the SWGB, in the case of a termination by FBMS, or to FBMS, in the case of a termination by the SWGB, or by its nature or timing cannot be cured during such period.

(e) Delay. By either FBMS or SWGB if the Merger shall not have been consummated on or before June 30, 2020, provided, however, that such date will be automatically extended to August 30, 2020, if the only outstanding condition to Closing under Article VI is the receipt of all Regulatory Approvals (the “Expiration Date”), unless the failure of the Closing to occur by such date shall be due to a material breach of this Agreement by the Party seeking to terminate this Agreement.

(f) Failure to Recommend; Etc. In addition to and not in limitation of FBMS’s termination rights under Section 7.01(e), by FBMS if (i) there shall have been a material breach of Section 5.04 or Section 5.09 by SWGB, or (ii) the board of directors of SWGB takes an Adverse Recommendation Action.

(g) Acceptance of Superior Proposal. By SWGB in connection with entering into a definitive agreement to effect a Superior Proposal after making an SWGB Subsequent Determination in accordance with Section 5.09(d).

(h) Decline in FBMS Common Stock Price. By SWGB, if the board of directors of SWGB so determines at any time during the five (5) day period commencing prior to the Determination Date, if, and only if, both of the following conditions are satisfied:

(i) The number obtained by dividing the FBMS Average Stock Price by the Initial FBMS Market Price (the “FBMS Ratio”) is less than 0.80; and

(ii) the FBMS Ratio is less than the number obtained by (1) dividing the Final Index Price by the Initial Index Price (the “Index Ratio”) and (2) subtracting 0.20 from such quotient, subject, however, to the following:

If SWGB elects to exercise its termination right under this Section 7.01(h), it shall give prompt written notice thereof to FBMS. Within five (5) Business Days following its receipt of such notice, FBMS shall have the option to adjust the per share Merger Consideration such that the per share value of the Merger Consideration (calculated using the FBMS Average Stock Price) is equal to or greater than the lesser of the following:

(x) an amount equal to the product of the Initial FBMS Market Price, the per share Merger Consideration (prior to any adjustment pursuant to this Section 7.01(h)), and 0.80; or

(y) an amount equal to (A) the product of the Index Ratio, 0.80, the per share Merger Consideration (prior to any adjustment pursuant to this Section 7.01(h)), and the FBMS Average Stock Price, divided by (B) the FBMS Ratio.

If FBMS so elects, it shall give written notice to SWGB of such election and the amount of increase in the per share Merger Consideration within the five (5) Business Day period following its receipt of notice of termination from SWGB, whereupon no termination shall have occurred pursuant to this Section 7.01(g) and this Agreement shall remain in full force and effect in accordance with its terms (except that the Merger Consideration shall have been so modified). Notwithstanding anything to the contrary in this Section 7.01(h), the per share Merger Consideration shall not be adjusted or otherwise fixed in any manner that would be reasonably likely to prevent the Merger from qualifying as a “reorganization” within the meaning of Section 368(a) of the Code, unless SWGB and FBMS so agree in writing.

(b) SWGB and FBMS each agree that the agreements contained in this Section 7.02 are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, FBMS would not enter into this Agreement; accordingly, if SWGB fails promptly to pay any amounts due under this Section 7.02, SWGB shall pay interest on such amounts from the date payment of such amounts were due to the date of actual payment at the rate of interest equal to the sum of (i) the rate of interest published from time to time in The Wall Street Journal, Eastern Edition (or any successor publication thereto), designated therein as the prime rate on the date such payment was due plus (ii) 200 basis points, together with the costs and expenses of FBMS (including reasonable legal fees and expenses) in connection with such suit.

NOW, THEREFORE, in consideration of, and as a material inducement to, FBMS entering into the Merger Agreement and proceeding with the transactions contemplated thereby, and in consideration of the expenses incurred and to be incurred by FBMS in connection therewith, Shareholder and FBMS agree as follows:

Section 1. Agreement to Vote Shares. Shareholder, solely in his, her or its capacity as a shareholder of SWGB, agrees that, while this Agreement is in effect, at any meeting of shareholders of SWGB, however called, or at any adjournment thereof, or in any other circumstances in which Shareholder is entitled to vote, consent or give any other approval in his, her or its capacity as a shareholder of SWGB, except as otherwise agreed to in writing in advance by FBMS, Shareholder shall:

(a) appear at each such meeting in person or by proxy or otherwise cause the Shares to be counted as present thereat for purposes of calculating a quorum; and

(b) vote (or cause to be voted), in person or by proxy, all the Shares as to which the Shareholder has, directly or indirectly, the right to vote or direct the voting, (i) in favor of adoption and approval of the Merger Agreement and the transactions contemplated thereby (including any amendments or modifications of the terms thereof approved by the board of directors of SWGB and adopted in accordance with the terms thereof); (ii) in favor of any proposal to adjourn or postpone such meeting, if necessary, to solicit additional proxies to approve the Merger Agreement; (iii) against any action or agreement that would result in a breach of any covenant, representation or warranty or any other obligation or agreement of SWGB contained in the Merger Agreement or of Shareholder contained in

this Agreement; and (iv) against any Acquisition Proposal (as defined in the Merger Agreement) or any other action, agreement or transaction that is intended, or could reasonably be expected, to impede, interfere or be inconsistent with, delay, postpone, discourage or materially and adversely affect consummation of the transactions contemplated by the Merger Agreement or this Agreement.

Shareholder further agrees not to vote or execute any written consent to rescind or amend in any manner any prior vote or written consent, as a shareholder of SWGB, to approve or adopt the Merger Agreement unless this Agreement shall have been terminated in accordance with its terms.

Section 2. No Transfers. Until the earlier of (i) the termination of this Agreement pursuant to Section 6 and (ii) receipt of the Requisite SWGB Shareholder Approval, Shareholder agrees not to, directly or indirectly, sell, transfer, pledge, assign or otherwise dispose of, or enter into any contract option, commitment or other arrangement or understanding with respect to the sale, transfer, pledge, assignment or other disposition of, any of the Shares, except the following transfers shall be permitted: (a) transfers by will or operation of Law, in which case this Agreement shall bind the transferee, (b) transfers pursuant to any pledge agreement, subject to the pledgee agreeing in writing, prior to such transfer, to be bound by the terms of this Agreement, (c) transfers in connection with estate and tax planning purposes, including transfers to relatives, trusts and charitable organizations, subject to each transferee agreeing in writing, prior to such transfer, to be bound by the terms of this Agreement, (d) transfers or the surrender of Shares in connection with the payment of any withholding taxes owed by the holder of an SWGB Restricted Share upon the vesting of an SWGB Restricted Share, and (e) such transfers as FBMS may otherwise permit in its sole discretion. Any transfer or other disposition in violation of the terms of this Section 2 shall be null and void.

Section 3. Representations and Warranties of Shareholder. Shareholder represents and warrants to and agrees with FBMS as follows:

(a) Shareholder has all requisite capacity and authority to enter into and perform his, her or its obligations under this Agreement.

(b) This Agreement has been duly executed and delivered by Shareholder, and assuming the due authorization, execution and delivery by FBMS, constitutes a valid and legally binding obligation of Shareholder enforceable against Shareholder in accordance with its terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles.

(c) The execution and delivery of this Agreement by Shareholder does not, and the performance by Shareholder of his, her or its obligations hereunder and the consummation by Shareholder of the transactions contemplated hereby will not, violate or conflict with, or constitute a default under, any agreement, instrument, contract or other obligation or any order, arbitration award, judgment or decree to which Shareholder is a party or by which Shareholder is bound, or any statute, rule or regulation to which Shareholder is subject or, in the event that Shareholder is a corporation, partnership, trust or other entity, any charter, bylaw or other organizational document of Shareholder.

(d) Shareholder is the record and beneficial owner of, or is the trustee that is the record holder of, and whose beneficiaries are the beneficial owners of, and has good title to all of the Shares, and the Shares are owned free and clear of any liens, security interests, charges or other encumbrances. The Shares do not include shares over which Shareholder exercises control in a fiduciary capacity for any other person or entity that is not an Affiliate of Shareholder, and no representation by Shareholder is made with respect thereto. Shareholder has the right to vote the Shares, and none of the Shares is subject to any voting trust or other agreement, arrangement or restriction with respect to the voting of the Shares, except as contemplated by this Agreement. Shareholder does not own, of record or beneficially, any shares of capital stock of SWGB other than the Shares or any other securities convertible into or exercisable or exchangeable for such capital stock, other than any SWGB Restricted Shares.

Section 4. No Solicitation. Shareholder acknowledges and agrees that Shareholder has reviewed and understands Section 5.09(a) of the Merger Agreement and hereby agrees that, from the date hereof until the termination of this Agreement in accordance with its terms, Shareholder shall be bound by Section 5.09(a) of the Merger Agreement to the same extent (but solely with respect to Shareholder’s own actions) as if Shareholder were directly bound by SWGBs obligations thereunder.

Section 5. Specific Performance; Remedies; Attorneys’ Fees. Shareholder acknowledges that it is a condition to the willingness of FBMS to enter into the Merger Agreement that Shareholder execute and deliver this Agreement and that it will be impossible to measure in money the damage to FBMS if Shareholder fails to comply with the obligations imposed by this Agreement and that, in the event of any such failure, FBMS will not have an adequate remedy at law or in equity. Accordingly, Shareholder agrees that injunctive relief or other equitable remedy is the appropriate remedy for any such failure and will not oppose the granting of such relief on the basis that FBMS has an adequate remedy at Law. Shareholder further agrees that Shareholder will not seek, and agrees to waive any requirement for, the securing or posting of a bond in connection with FBMS’ seeking or obtaining such equitable relief. In addition, after discussing the matter with Shareholder, FBMS shall have the right to inform any third party that FBMS reasonably believes to be, or to be contemplating, participating with Shareholder or receiving from Shareholder assistance in violation of this Agreement, of the terms of this Agreement and of the rights of FBMS hereunder, and that participation by any such persons with Shareholder in activities in violation of Shareholder’s agreement with FBMS set forth in this Agreement may give rise to claims by FBMS against such third party.

Section 6. Term of Agreement; Termination. The term of this Agreement shall commence on the date hereof. This Agreement may be terminated at any time prior to consummation of the transactions contemplated by the Merger Agreement by the mutual written agreement of the parties hereto, and shall be automatically terminated upon the earlier to occur of (a) the Effective Time, (b) the amendment of the Merger Agreement in any manner that materially and adversely affects any of Shareholder’s rights set forth therein (including, for the avoidance of doubt, any reduction to the Merger Consideration), (c) termination of the Merger Agreement or (d) two (2) years from the date hereof. Upon such termination, no party shall have any further obligations or liabilities hereunder; provided, however, that such termination shall not relieve any party from liability for any breach of this Agreement prior to such termination.

Section 7. Entire Agreement. This Agreement represents the entire understanding of the parties hereto with reference to the transactions contemplated hereby, and this Agreement supersedes any and all other oral or written agreements heretofore made.

Section 8. Modification and Waiver. No provision of this Agreement may be modified, waived or discharged unless such waiver, modification or discharge is agreed to in writing signed by each party. No waiver by either party hereto at any time of any breach by the other party hereto of, or compliance with, any condition or provision of this Agreement to be performed by such other party shall be deemed a waiver of dissimilar provisions or conditions at the same or any prior subsequent time.

Section 9. Severability. In the event that any one or more provisions of this Agreement shall for any reason be held invalid, illegal or unenforceable in any respect, by any court of competent jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provisions of this Agreement and the parties shall use their commercially reasonable efforts to substitute a valid, legal and enforceable provision which, insofar as practical, implements the purposes and intents of this Agreement.

Section 10. Capacity as Shareholder. This Agreement shall apply to Shareholder solely in his, her or its capacity as a shareholder of SWGB, and it shall not apply in any manner to Shareholder in his, her or its capacity as a director or officer of SWGB, if applicable. Nothing contained in this Agreement shall be deemed to apply to, or limit in any manner, the obligations of Shareholder to comply with his, her or its fiduciary duties as a director or officer of SWGB, if applicable.

Section 11. Governing Law. This Agreement shall be governed by, and interpreted and enforced in accordance with, the internal, substantive laws of the State of Mississippi, without regard for conflict of law provisions.

Section 12. Jurisdiction. Any civil action, counterclaim, proceeding or litigation arising out of or relating to this Agreement shall be brought in the courts of record of the State of Mississippi in Forrest County or the United States District Court, Southern District of Mississippi. Each party consents to the jurisdiction of such Mississippi court in any such civil action, counterclaim, proceeding or litigation and waives any objection to the laying of venue of any such civil action, counterclaim, proceeding or litigation in such Mississippi court. Service of any court paper may be effected on such party by mail, as provided in this letter, or in such other manner as may be provided under applicable Laws.

Section 13. WAIVER OF JURY TRIAL. EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT.

Section 14. Waiver of Appraisal Rights; Further Assurances. To the extent permitted by applicable law, Shareholder hereby waives any rights of appraisal or rights to dissent from the Merger or demand fair value for his, her or its Shares in connection with the Merger, in each case, that Shareholder may have under applicable law. From time to time prior to the termination of this Agreement, at FBMS’s request and without further consideration, Shareholder shall execute and deliver such additional documents and take all such further action as may be reasonably necessary or desirable to effect the actions and consummate the transactions contemplated by this Agreement. Shareholder further agrees not to commence or participate in, and to take all actions necessary to opt out of any class in any class action with respect to, any claim, derivative or otherwise, against FBMS, The First Bank, SWGB, Southwest Georgia Bank or any of their respective successors relating to the negotiation, execution or delivery of this Agreement or the Merger Agreement or the consummation of the Merger.

Section 15. Disclosure. Shareholder hereby authorizes SWGB and FBMS to publish and disclose in any announcement or disclosure required by the Securities and Exchange Commission and in the Proxy Statement-Prospectus such Shareholder’s identity and ownership of the Shares and the nature of Shareholder’s obligations under this Agreement; provided, however, that FBMS shall provide Shareholder written drafts of any such disclosure and consider in good faith Shareholder’s comments thereto.

Section 16. Ownership. Nothing in this Voting Agreement shall be construed to give FBMS any rights to exercise or direct the exercise of voting power as owner of the Shares or to vest in FBMS any direct or indirect ownership or incidents of ownership of or with respect to any of the Shares. All rights, ownership and economic benefits of and relating to the Shares shall remain vested in and belong to the Shareholder, notwithstanding the provisions of this Voting Agreement, and FBMS shall have no authority to manage, direct, superintend, restrict, regulate, govern or administer any of the policies or operations of SWGB or to exercise any power or authority to direct the Shareholder in voting any of the Shares, except as otherwise expressly provided herein.

Section 17. Fiduciary Duty. No provision of this Agreement shall preclude or in any way limit the Shareholder (or any representative of the Shareholder) from exercising his or her fiduciary duties as a member of the Board of Directors or an officer of SWGB.

Section 18. Counterparts. This Agreement may be executed and delivered by facsimile or by electronic data file and in one or more counterparts, all of which shall be considered one and the same agreement and shall become effective when one or more counterparts have been signed by each of the parties and delivered to the other party, it being understood that all parties need not sign the same counterpart. Signatures delivered by facsimile or by electronic data file shall have the same effect as originals.

NON-COMPETITION AND NON-DISCLOSURE AGREEMENT

This Non-Competition and Non-Disclosure Agreement (the “Agreement”), is dated as of December 18, 2019, by and between the undersigned, an individual resident of the State of Georgia (“Director”), and The First Bancshares, Inc., a Mississippi corporation (“FBMS”). All capitalized terms used but not defined herein shall have the meanings assigned to them in the Merger Agreement (defined below).

RECITALS:

WHEREAS, concurrently with the execution of this Agreement, FBMS and Southwest Georgia Financial Corporation, a Georgia corporation (“SWGB”), are entering into an Agreement and Plan of Merger (as such agreement may be subsequently amended or modified, the “Merger Agreement”), pursuant to which (i) SWGB will merge with and into FBMS, with FBMS as the surviving entity, and (ii) Southwest Georgia Bank, a Georgia state-chartered bank and wholly-owned subsidiary of SWGB, will merge with and into The First, National Association, a national banking association and wholly-owned subsidiary of FBMS (“The First”), with The First as the surviving bank (collectively, the “Merger”);

WHEREAS, Director is a shareholder of SWGB and, as a result of the Merger and pursuant to the transactions contemplated by the Merger Agreement, Director is expected to receive significant consideration in exchange for the shares of SWGB Common Stock held by Director;

WHEREAS, as of and prior to the date hereof, Director serves and has served as a member of the Board of Directors of SWGB or Southwest Georgia Bank, and, therefore, Director has knowledge of the Confidential Information and Trade Secrets (each as hereinafter defined);

WHEREAS, as a result of the Merger, FBMS will succeed to all of the Confidential Information and Trade Secrets, for which FBMS as of the Effective Time will have paid valuable consideration and desires reasonable protection; and

WHEREAS, it is a material prerequisite to the consummation of the Merger that each director of SWGB and Southwest Georgia Bank, including Director, enter into this Agreement.

AGREEMENT:

NOW, THEREFORE, in consideration of these premises and the mutual covenants and undertakings herein contained, FBMS and Director, each intending to be legally bound, covenant and agree as follows:

Section 1. Restrictive Covenants.

(a) Director acknowledges that (i) FBMS has separately bargained for the restrictive covenants in this Agreement; and (ii) the types and periods of restrictions imposed by the covenants in this Agreement are fair and reasonable to Director and such restrictions will not prevent Director from earning a livelihood.

(b) Having acknowledged the foregoing, solely in the event that the Merger is consummated, Director covenants and agrees with FBMS as follows:

(i) From and after the Effective Time, Director will not disclose or use any Confidential Information or Trade Secrets for so long as such information remains Confidential Information or a Trade Secret, as applicable, for any purpose, except for any disclosure that is required by applicable Law. In the event that Director is required by Law to disclose any Confidential Information, Director will: (A) if and to the extent permitted by such Law, provide FBMS with prompt notice of such requirement prior to the disclosure so that FBMS may waive the requirements of this Agreement or seek an appropriate protective order at FBMS’s sole expense; and (B) use reasonable efforts (without being required to incur personal expense) to obtain assurances that any Confidential Information disclosed will be accorded confidential treatment. If, in the absence of a waiver or protective order, Director is nonetheless required to disclose Confidential Information, disclosure may be made only as to that portion of the Confidential Information that is required to be disclosed. Nothing contained in this Agreement limits the Director’s ability to file a charge or complaint with the Equal Employment Opportunity Commission, the Federal Deposit Insurance Corporation, the Board of Governors of the Federal Reserve System, the Securities and Exchange Commission or any other federal, state or local

A-C-2

TABLE OF CONTENTS

governmental agency or commission that has jurisdiction over SWGB or any of its subsidiaries or affiliates (the “Government Agencies”). The Director further understands that this Agreement does not limit his ability to communicate with any Government Agencies or otherwise participate in any investigation or proceeding that may be conducted by any Government Agency, including providing documents or other information, without notice to SWGB or any of its subsidiaries or affiliates. This Agreement does not limit the Director’s right to receive an award for information provided to any Government Agencies. In addition, pursuant to the Defend Trade Secrets Act of 2016, the Director understands that an individual may not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that (i) is made (A) in confidence to a federal, state or local government official, either directly or indirectly, or to an attorney; and (B) solely for the purpose of reporting or investigating a suspected violation of law; or (ii) is made in a complaint or other document that is filed under seal in a lawsuit or other proceeding. Further, an individual who files a lawsuit for retaliation by an employer for reporting a suspected violation of law may disclose the employer’s trade secrets to the attorney and use the trade secret information in the court proceeding if the individual (y) files any document containing the trade secret under seal; and (z) does not disclose the trade secret, except pursuant to court order.

(ii) Except as expressly provided on Schedule I to this Agreement, for a period beginning at the Effective Time and ending two (2) years after the Effective Time, Director will not (except on behalf of or with the prior written consent of FBMS), on Director’s own behalf or in the service or on behalf of others, solicit or attempt to solicit any customer of FBMS, The First, SWGB or Southwest Georgia Bank (each a “Protected Party”), including customers of Southwest Georgia Bank actually known by Director to be actively sought by Southwest Georgia Bank as of the Effective Time, for the purpose of providing products or services that are Competitive (as hereinafter defined) with those offered or provided by any Protected Party.

(iii) Except as expressly provided on Schedule I to this Agreement, for a period beginning at the Effective Time and ending two (2) years after the Effective Time, Director will not (except on behalf of or with the prior written consent of FBMS), either directly or indirectly, on Director’s own behalf or in the service or on behalf of others, act as a director, manager, officer or employee of any business which is the same as or essentially the same as the business conducted by any Protected Party and which has an office located within the Restricted Territory.

(iv) For a period beginning at the Effective Time and ending two (2) years after the Effective Time, Director will not, on Director’s own behalf or in the service or on behalf of others, solicit or recruit or attempt to solicit or recruit, directly or by assisting others, any employee of any Protected Party who was an employee of Southwest Georgia Bank prior to the Effective Time, whether or not such employee is a full-time employee or a temporary employee of such Protected Party, whether or not such employment is pursuant to a written agreement and whether or not such employment is for a determined period or is at will, to cease working for such Protected Party; provided that the foregoing will not prevent the placement of any general solicitation for employment not specifically directed towards employees of any Protected Party or hiring any such person as a result thereof.

(i) “Competitive,” with respect to particular products or services, means products or services that are the same as or similar to the products or services of any Protected Party.

(ii) “Confidential Information” means data and information:

(A) relating to the business of SWGB and its Subsidiaries, including Southwest Georgia Bank, regardless of whether the data or information constitutes a Trade Secret;

(B) disclosed to Director or of which Director became aware as a consequence of Director’s relationship with SWGB and/or Southwest Georgia Bank;

(C) having value to SWGB and/or Southwest Georgia Bank and, as a result of the consummation of the transactions contemplated by the Merger Agreement, FBMS and/or The First; and

A-C-3

TABLE OF CONTENTS

(D) not generally known to competitors of SWGB or FBMS (including competitors to Southwest Georgia Bank or The First).

Confidential Information shall include Trade Secrets, methods of operation, names of customers, price lists, financial information and projections, personnel data and similar information; provided, however, that the terms “Confidential Information” and “Trade Secrets” shall not mean data or information that (x) has been disclosed to the public, except where such public disclosure has been made by Director without authorization from SWGB or FBMS, (y) has been independently developed and disclosed by others, or (z) has otherwise entered the public domain through lawful means.

(iii) “Restricted Territory” means each county in Georgia where Southwest Georgia Bank operates a banking office at the Effective Time and each contiguous county.

(iv) “Trade Secret” means information, without regard to form, including technical or nontechnical data, a formula, a pattern, a compilation, a program, a device, a method, a technique, a drawing, a process, financial data, financial plans, product plans or a list of actual or potential customers or suppliers, that is not commonly known by or available to the public and which information:

(A) derives economic value, actual or potential, from not being generally known to, and not being readily ascertainable by proper means by, other persons who can obtain economic value from its disclosure or use; and

(B) is the subject of efforts that are reasonable under the circumstances to maintain its secrecy.

(d) Director acknowledges that irreparable loss and injury would result to FBMS upon the breach of any of the covenants contained in this Section 1 and that damages arising out of such breach would be difficult to ascertain. Director hereby agrees that, in addition to all other remedies provided at law or in equity, FBMS may petition and obtain from a court of law or equity, without the necessity of proving actual damages and without posting any bond or other security, both temporary and permanent injunctive relief to prevent a breach by Director of any covenant contained in this Section 1, and shall be entitled to an equitable accounting of all earnings, profits and other benefits arising out of any such breach. In the event that the provisions of this Section 1 should ever be determined to exceed the time, geographic or other limitations permitted by applicable Law, then such provisions shall be modified so as to be enforceable to the maximum extent permitted by Law. If such provision(s) cannot be modified to be enforceable, the provision(s) shall be severed from this Agreement to the extent unenforceable. The remaining provisions and any partially enforceable provisions shall remain in full force and effect.

Section 2. Term; Termination.

Board of Directors
Southwest Georgia Financial Corporation
201 First Street, SE
Moultrie, GA 31768

Members of the Board of Directors:

We understand that Southwest Georgia Financial Corporation (NYSEAM: SGB) (“SGB”) holding company of Southwest Georgia Bank, intends to enter into an Agreement and Plan of Merger (the “Agreement”) by and between SGB and The First Bancshares, Inc. (NASDAQ: FBMS) (“First Bancshares”), holding company for The First, A National Banking Association (“The First”) (the “Merger”). At the Effective Time, by virtue of the Merger and subject to the terms and conditions of the Agreement, each share of SGB common stock issued and outstanding shall be converted into the right to receive 1.0000 shares of First Bancshares common stock. Based upon the closing stock price of First Bancshares of $34.50 as of December 17, 2019, the implied value of the aggregate merger consideration was $87.9 million (the “Merger Consideration”).

You have requested that BSP Securities, LLC, a Performance Trust Company (“BSP” or “we”) render an opinion as of the date hereof (this “Opinion”) to the Board of Directors of SGB (the “Board”) as to whether the Merger Consideration pursuant to the Agreement is fair, from a financial point of view, to the holders of SGB common stock.

In connection with this Opinion, we have made such reviews, analyses and inquiries as we have deemed necessary and appropriate under the circumstances. Among other things, we have:

(i)

reviewed a draft, dated December 16th, of the Agreement;

(ii)

reviewed certain publicly available business and financial information relating to SGB, Southwest Georgia Bank, First Bancshares and The First;

(iii)

reviewed certain other business, financial and operating information relating to SGB, Southwest Georgia Bank, First Bancshares and The First provided to us by the management of SGB and the management of First Bancshares, including financial forecasts for SGB for the 2019 to 2023 fiscal years ending December 31, and financial forecasts for First Bancshares for the 2019 to 2024 fiscal years ending December 31;

(iv)

met with, either by phone or in person, certain members of the management of SGB and First Bancshares to discuss the business and prospects of SGB and First Bancshares and the proposed Merger;

(v)

reviewed and compared certain financial metrics of SGB with certain financial metrics of First Bancshares that we deemed relevant;

(vi)

reviewed certain financial data of SGB and First Bancshares, and compared that data with similar data for companies with publicly traded equity securities that we deemed relevant;

(vii)

reviewed certain financial terms of the proposed Transaction and compared certain of those terms with the publicly available financial terms of certain transactions that have recently been effected or announced; and

(viii)

considered such other information, financial studies, analyses and investigations and financial, economic and market criteria that we deemed relevant.

In connection with our review, we have not independently verified any information, including the foregoing information, and we have assumed and relied upon all data, material and other information furnished, or otherwise made available, to us, discussed with or reviewed by us, or publicly available, being complete and accurate in all material respects and we do not assume any responsibility with respect to such data, material and other information. With respect to the financial forecasts and projections for SGB that we have used in our analyses, the management of SGB has advised us, and we have assumed, that such forecasts and projections have been reasonably prepared in good faith on bases reflecting the best currently available estimates and judgments of the management of SGB as to the future financial performance of SGB and we express no opinion with respect to such forecasts, projections, estimates or the assumptions on which they are based.

We have relied upon and assumed, without independent verification, that (a) the representations and warranties of all parties to the Agreement and all other related documents and instruments that are referred to therein are true and correct, (b) each party to all such agreements will perform all of the covenants and agreements required to be performed by such party, (c) all conditions to the consummation of the Merger will be satisfied without waiver thereof, and (d) the Merger will be consummated in a timely manner in accordance with the terms described in the Agreement provided to us, without any amendments or modifications thereto or any adjustments to the consideration. We have relied upon and assumed, without independent verification, that there has been no material change in the business, assets, liabilities, financial condition, results of operations, cash flows or prospects of SGB and First Bancshares since the respective dates of the most recent financial statements and other information, financial or otherwise, provided to us that would be material to our analyses or this Opinion, and that there is no information or any facts that would make any of the information reviewed by us incomplete or misleading. We have also relied upon and assumed without independent verification, with your consent, that, in the course of obtaining any regulatory or third party consents, approvals or agreements in connection with the Merger, no delay, limitation, restriction or condition will be imposed that would have an adverse effect on SGB, First Bancshares or the contemplated benefits of the Merger and that the Merger will be consummated in accordance with the terms of the Agreement without waiver, modification or amendment of any term, condition or provision thereof that would be material to our analyses or this Opinion. We have relied upon and assumed, with your consent, that the Agreement, when executed by the parties thereto, will conform to the draft reviewed by us in all respects material to our analyses.

This Opinion only addresses the fairness, from a financial point of view, of the Merger Consideration to the holders of SGB common stock pursuant to the Agreement in the manner set forth above and this Opinion does not address any other aspect or implication of the Merger or any agreement, arrangement or understanding entered into in connection with the Merger or otherwise, including, without limitation, the amount or nature of, or any other aspect relating to, any compensation to any officers, trustees, directors or employees of any party to the Merger, class of such persons or shareholders of First Bancshares, relative to the Merger Consideration or otherwise.

This Opinion is necessarily based upon information made available to us as of the date hereof and financial, economic, market and other conditions as they exist and can be evaluated on the date hereof. As you are aware, the credit, financial and stock markets have been experiencing unusual volatility and we express no opinion or view as to any potential effects of such volatility on SGB, First Bancshares or the Merger. We have not undertaken, and are under no obligation, to update, revise, reaffirm or withdraw this Opinion, or otherwise comment on or consider events occurring after the date hereof. This Opinion does not address the relative merits of the Merger as compared to alternative strategies that might be available to

SGB, nor does it address the underlying business decision of SGB or the Board to approve, recommend or proceed with the Merger. Furthermore, no opinion, counsel or interpretation is intended in matters that require legal, regulatory, accounting, insurance, tax or other similar professional advice. It is assumed that such opinions, counsel or interpretations have been or will be obtained from the appropriate professional sources. Furthermore, we have relied on, with your consent, advice of the outside counsel and the independent accountants of SGB, and on the assumptions of the management of SGB and First Bancshares, as to all legal, regulatory, accounting, insurance and tax matters with respect to SGB, First Bancshares and the Merger.

We have not been requested to make, and have not made, any physical inspection or an independent evaluation or appraisal of any assets or liabilities (contingent or otherwise) of SGB or First Bancshares, nor have we been furnished with any such evaluations or appraisals, with the exception of a third party loan review of SGB and First Bancshares. In addition, we are not experts in evaluating loan, lease, investment or trading portfolios for purposes of assessing the adequacy of the allowances for losses, or evaluating loan servicing rights or goodwill for purposes of assessing any impairment thereto. We did not make an independent evaluation of the adequacy of SGB’s or First Bancshares’s allowances for such losses, nor have we reviewed any individual loan or credit files or investment or trading portfolios. In all cases, we have assumed that SGB’s and First Bancshares’s allowances for such losses are adequate to cover such losses. We have not evaluated the solvency of SGB or First Bancshares or the solvency or fair value of SGB, First Bancshares or any other entity or person or their respective assets or liabilities under any state or federal laws relating to bankruptcy, insolvency, fraudulent conveyance or similar matters.

We and our affiliates have in the past provided, may currently be providing and may in the future provide investment banking and other financial services to SGB, First Bancshares and certain of their respective affiliates, for which we and our affiliates have received and would expect to receive compensation. We are a broker-dealer engaged in securities trading and brokerage activities as well as providing investment banking and other financial services. In the ordinary course of business, we and our affiliates may acquire, hold or sell, for our and our affiliates own accounts and the accounts of customers, equity, debt and other securities and financial instruments (including bank loans and other obligations) of SGB, First Bancshares and certain of their affiliates, as well as provide investment banking and other financial services to such companies and entities. BSP has adopted policies and procedures designed to preserve the independence of its investment advisory analysts whose views may differ from those of the members of the team of investment banking professionals that advised SGB.

We have acted as financial advisor to SGB in connection with the Merger and will receive customary investment banking fees totaling approximately $924,000 for our services, a significant portion of which is contingent upon the consummation of the Merger. SGB previously paid BSP a $20,000 retainer, and it will pay BSP a fee of $25,000 upon delivery of this Opinion. In addition, SGB has agreed to indemnify us and certain related parties for certain liabilities arising out of or related to our engagement and to reimburse us for certain expenses incurred in connection with our engagement.

This Opinion and any other advice or analyses (written or oral) provided by BSP were provided solely for the use and benefit of the Board (in its capacity as such) in connection with the Board’s consideration of the Merger and does not, confer any rights or remedies upon any other person, and is not intended to be used, and may not be used, for any other purpose, without the express, prior written consent of BSP. This Opinion may not be disclosed, reproduced, disseminated, quoted, summarized or referred to at any time, in any manner or for any purpose, nor shall any references to BSP or any of its affiliates be made by any recipient of this Opinion, without the prior, written consent of BSP, except as required by law. This Opinion should not be construed as creating, and BSP shall not be deemed to have, any fiduciary duty to the Board, SGB, any security holder or creditor of SGB or any other person, regardless of any prior or ongoing advice

or relationships. This Opinion does not constitute advice or a recommendation to any security holder of SGB or any other person or entity with respect to how such security holder or other person or entity should vote or act with respect to any matter relating to the Merger. The issuance of this Opinion was approved by an authorized internal committee of BSP.

In connection with the Merger, the undersigned, acting as an independent financial advisor to SGB, hereby consents to the inclusion of our opinion letter to the Board of Directors of SGB as an Annex to, and the references to our firm and such opinion in, the proxy statement/prospectus relating to the proposed Merger. In giving such consent, we do not admit that we come within the category of persons whose consent is required under Section 7 of the Securities Act of 1933, as amended (the “Act”), or the rules and regulations of the Securities and Exchange Commission thereunder (the “Regulations”), nor do we admit that we are experts with respect to any part of such proxy statement/prospectus within the meaning of the term “experts” as used in the Act or the Regulations.

Based upon and subject to the foregoing, and in reliance thereon, it is our opinion that, as of the date hereof, the Merger Consideration pursuant to the Agreement is fair, from a financial point of view, to the holders of SGB common stock.

Sincerely,

BSP Securities, LLC, A Performance Trust Company

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20.

Indemnification of Directors and Officers

Section 79-4-8.50 through 79-4-8.59 of the MBCA provide First Bancshares with broad powers and authority to indemnify its directors and officers and to purchase and maintain insurance for such purposes and mandate the indemnification of First Bancshares’ directors under certain circumstances. First Bancshares’ bylaws also provide it with the power and authority, to the fullest extent legally permissible under the MBCA, to indemnify its directors and officers, persons serving at the request of First Bancshares or for its benefit as directors or officers of another corporation, and persons serving as First Bancshares’ representatives or agents in certain circumstances.

Under its bylaws, First Bancshares shall indemnify any person who becomes subject to a lawsuit or proceeding by reason of service as a director of First Bancshares or any other corporation which the person served as a director at the request of First Bancshares. Except as noted in the next paragraph, such persons are entitled to be indemnified against judgments, penalties, fines, settlements, and reasonable expenses actually incurred in connection with the proceeding, provided the indemnified person acted in a manner he believed in good faith to be in or not opposed to the best interests of First Bancshares, and in the case of any criminal proceeding, had no reasonable cause to believe such conduct was unlawful.

To the extent First Bancshares has funds reasonably available to be used for this purpose, indemnified persons are entitled to have First Bancshares advance expenses incurred prior to final disposition of the proceeding, upon delivery of (1) a written affirmation by such person of his good faith belief that the standard of conduct necessary for indemnification has been met, and (2) a written undertaking to repay the amounts advanced if it is ultimately determined that the standard of conduct has not been met. The board of directors shall then make a determination that the facts then known would not preclude indemnification under the MBCA. Pursuant to such authority and the provisions of First Bancshares’ bylaws, First Bancshares has purchased insurance against certain liabilities that may be incurred by it and its officers and directors.

Under the bylaws, indemnification may not be authorized if it is established that the person appropriated, in violation of his or her duties, any business opportunity of First Bancshares, engaged in acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, approved dividends or other distributions in violation of the MBCA, or engaged in any transaction in which the director derived an improper personal benefit.

In addition to the bylaws of First Bancshares, the MBCA requires that a corporation indemnify a director who was wholly successful, on the merits or otherwise, in the defense of any proceeding to which he or she was a party because he or she is or was a director of the corporation against reasonable expenses incurred by him or her in connection with the proceeding. The MBCA also provides that, upon application of a director, a court may order indemnification if it determines that the director is entitled to such indemnification under the applicable standard of the MBCA.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers, and controlling persons of First Bancshares pursuant to its articles of incorporation or bylaws, or otherwise, First Bancshares has been advised that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable.

The registrant undertakes that every prospectus: (1) that is filed pursuant to paragraph (c) immediately preceding, or (2) that purports to meet the requirements of Section 10(a)(3) of the Act and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(d) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful

defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

The undersigned registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11, or 13 of Form S-4, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

The undersigned registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.
