PRELIMINARY — SUBJECT TO COMPLETION — DATED OCTOBER 11, 2022

Joint Proxy Statement/Prospectus

MERGER PROPOSED — YOUR VOTE IS VERY IMPORTANT

To the Shareholders of The First Bancshares, Inc. and Heritage Southeast Bancorporation, Inc.:

The boards of directors of The First Bancshares, Inc., or First Bancshares, and Heritage Southeast Bancorporation, Inc., or HSBI, have each unanimously approved the acquisition of HSBI by First Bancshares. The acquisition will be accomplished pursuant to the terms of an Agreement and Plan of Merger, dated as of July 27, 2022, which we refer to as the merger agreement, by and between First Bancshares and HSBI, whereby HSBI will be merged with and into First Bancshares, which we refer to as the merger. Immediately following the merger of HSBI with and into First Bancshares, Heritage Southeast Bank, the wholly owned bank subsidiary of HSBI, will merge with and into First Bancshares’ wholly owned bank subsidiary, The First Bank, or The First, with The First as the surviving bank, which we refer to as the bank merger.

If the merger is completed, each share of HSBI common stock, which we refer to as HSBI stock, issued and outstanding immediately prior to the effective time of the merger will be converted into the right to receive 0.965, or the exchange ratio, of a share of First Bancshares common stock, which we refer to as the merger consideration.

Although the number of shares of First Bancshares common stock that HSBI 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 HSBI shareholders and First Bancshares shareholders vote on the merger. First Bancshares common stock is currently quoted on the NASDAQ Global Market. On July 26, 2022, 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 $29.68 per share, the exchange ratio represented approximately $28.64 in value for each share of HSBI stock to be converted into First Bancshares common stock. Based on the most recent reported closing sale price of First Bancshares common stock on [ ], 2022 of $[ ] per share, the exchange ratio represented $[ ] in value for each share of HSBI stock to be converted into First Bancshares common stock. Based on the exchange ratio and the number of shares of HSBI stock outstanding, the maximum number of shares of First Bancshares common stock offered by First Bancshares and issuable in the merger is 6,962,435. We urge you to obtain current market quotations for the price of First Bancshares common stock (trading symbol “FBMS”) because the value of the per share stock consideration will fluctuate based on First Bancshares’ common stock price.

HSBI will hold a special meeting of its shareholders, referred to as the HSBI special meeting, where HSBI shareholders will be asked to consider and vote upon (1) a proposal to approve the merger agreement, (2) a proposal to approve certain payments to be made to Brad Serff if the transaction is completed, so that these payments are not subject to Section 280G of the Internal Revenue Code of 1986, as amended, which we refer to as the 280G proposal, and (3) a proposal to adjourn the HSBI special meeting, if necessary or appropriate, to solicit additional proxies in favor of the proposal to approve the merger agreement. The HSBI special meeting will be held at [ ], on [ ], 2022, at [ ], Eastern Time, subject to any adjournment or postponement thereof. The board of directors of HSBI 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 HSBI, has unanimously approved the merger agreement and the merger and unanimously recommends that the shareholders of HSBI vote “FOR” the proposal to approve the merger agreement, “FOR” the 280G proposal and “FOR” the proposal to adjourn the HSBI special meeting, if necessary or appropriate, to solicit additional proxies in favor of the proposal to approve the merger agreement.

First Bancshares will hold a special meeting of its shareholders, referred to as the First Bancshares special meeting, where First Bancshares shareholders will be asked to consider and vote upon (1) a proposal

TABLE OF CONTENTS

to approve the merger agreement, including the issuance of shares of First Bancshares common stock in the merger, and (2) a proposal to adjourn the First Bancshares special meeting, if necessary or appropriate, to solicit additional proxies in favor of the proposal to approve the merger agreement. The First Bancshares special meeting will be held at [ ], on [ ], 2022, at [ ], Central Time, subject to any adjournment or postponement thereof. The board of directors of First Bancshares 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 First Bancshares, has unanimously approved the merger agreement and the merger and unanimously recommends that the shareholders of First Bancshares vote “FOR” the proposal to approve the merger agreement, including the issuance of shares of First Bancshares common stock in the merger, and “FOR” the proposal to adjourn the First Bancshares special meeting, if necessary or appropriate, to solicit additional proxies in favor of the proposal to approve the merger agreement.

Your vote is very important, regardless of the number of shares you own. Whether or not you expect to attend your company’s special meeting, the details of which are described in the accompanying joint proxy statement/prospectus, please promptly submit your proxy by telephone, by the Internet or by completing, signing, dating and returning your signed proxy card(s) in the enclosed prepaid return envelope so that your shares may be represented at the applicable special meeting.

This document, which serves as a proxy statement for the First Bancshares and HSBI special meetings and as a prospectus for the shares of First Bancshares common stock to be issued to HSBI shareholders in the merger, describes each company’s special meeting, the merger, the documents related to the merger and other related matters. Please carefully read this entire proxy statement/prospectus, including “Risk Factors,” beginning on page 35, for a discussion of the risks relating to the proposed merger and owning First Bancshares common stock after the merger.

QUESTIONS AND ANSWERS

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

What is the merger?

First Bancshares and HSBI have entered into an Agreement and Plan of Merger, dated as of July 27, 2022, which we refer to as the “merger agreement”. Pursuant to the merger agreement, HSBI will merge with and into First Bancshares, with First Bancshares continuing as the surviving entity, in a transaction we refer to as the “merger.” Immediately following the merger, Heritage Southeast Bank, HSBI’s wholly owned subsidiary, will merge with and into The First Bank, the wholly owned subsidiary of First Bancshares, with The First Bank as the surviving bank, in a transaction we refer to as the “bank merger.”

First Bancshares will hold a special meeting of its shareholders, which we refer to as the “First Bancshares special meeting,” and HSBI will hold a special meeting of its shareholders, which we refer to as the “HSBI special meeting,” to obtain the required shareholder approvals, and you are being provided with this joint proxy statement/prospectus in connection with those meetings.

A copy of the merger agreement is attached to this joint proxy statement/prospectus as Annex A. We urge you to carefully read this joint proxy statement/prospectus, the annexes to, and the documents incorporated by reference in, this joint proxy statement/prospectus.

Why am I receiving this joint proxy statement/prospectus?

In order to complete the merger, among other things:

•

First Bancshares shareholders must approve the First Bancshares merger proposal; and

•

HSBI shareholders must approve the HSBI merger proposal.

Each of First Bancshares and HSBI is sending this joint proxy statement/prospectus to its shareholders to help them decide how to vote their shares of common stock with respect to such matters to be considered at their respective special meetings of shareholders.

Information about these meetings, the merger and the other business to be considered by First Bancshares shareholders at its special meeting or by HSBI shareholders at its special meeting, as applicable, is contained in this joint proxy statement/prospectus and you should read it carefully.

This document constitutes both a joint proxy statement of First Bancshares and HSBI and a prospectus of First Bancshares. It is a joint proxy statement because each of the boards of directors of First Bancshares and HSBI is soliciting proxies from their shareholders using this document. It is a prospectus because First Bancshares, in connection with the merger, will issue shares of First Bancshares common stock to HSBI shareholders, and this joint proxy statement/prospectus contains information about that common stock.

What will HSBI shareholders receive in the merger?

TABLE OF CONTENTS

common stock upon the completion of the merger will instead receive cash (without interest and rounded to the nearest whole cent) in an amount equal to such fractional part of a share of First Bancshares common stock, rounded to the nearest one hundredth of a share, multiplied by the average of the daily volume weighted average price of First Bancshares common stock on the NASDAQ Global Market for the ten trading days ending on the trading day immediately prior to the determination date. The determination date is defined as the date that is five days prior to the closing of the merger.

All stock options awarded under the HSBI equity plans will fully vest at the closing of the merger and will be converted automatically into the right to receive an amount of cash equal to the product of (i) the excess, if any, of (A) the product of (x) the exchange ratio multiplied by (y) $29.68 (representing the closing price of the First Bancshares’ common stock on the last trading day prior to the signing of the Merger Agreement), over (ii) the per share exercise price of the option to acquire shares of HSBI common stock prior to the effective time of the merger, multiplied by (B) the number of shares of HSBI common stock subject to such option prior to the effective time of the merger, rounding up to the nearest cent.

The merger agreement provides that outstanding and unvested restricted shares of HSBI pursuant to its equity plans will fully vest at the closing of the merger and automatically be converted into the right to receive the merger consideration.

Additionally, HSBI previously entered into supplemental executive retirement benefits agreements with certain individuals, which we refer to as the “SERP agreements”, pursuant to which part or all of the retirement benefit would be paid in the form of cash or shares of HSBI common stock. Prior to the execution of the merger agreement, all individual parties to the SERP agreements entered into termination agreements, pursuant to which their respective SERP agreements will be terminated at the effective time of the merger in exchange for a lump sum payment with regard to the cash-based retirement benefit. Pursuant to those termination agreements, all obligations to issue any shares of HSBI common stock will be terminated at the effective time of the merger, and each share of HSBI common stock that would otherwise be issuable under the applicable SERP agreement, whether vested or unvested, shall be converted into the right to receive 0.965 of a share of First Bancshares common stock.

HSBI 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, which we refer to as the average closing price, is less than $23.74, and (ii) the decline in the price of First Bancshares common stock (as measured by the average closing price divided by $29.68) 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 $116.02); provided, however, that First Bancshares has the option, but not the obligation, to adjust the exchange ratio to prevent the termination of merger agreement.

Will the value of the merger consideration change between the date of this joint 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 joint proxy statement/prospectus and the completion of the merger. HSBI shareholders will receive 0.965 share of First Bancshares common stock for each share of HSBI common they hold. Any fluctuation in the market price of First Bancshares common stock after the date of this joint proxy statement/prospectus will change the value of the shares of First Bancshares common stock that HSBI shareholders may receive.

TABLE OF CONTENTS

What vote is required to approve each proposal at the First Bancshares special meeting?

First Bancshares merger proposal. Approval of the First Bancshares merger proposal requires the affirmative vote of a majority of the issued and outstanding shares of First Bancshares common stock entitled to vote. First Bancshares shareholders must approve the First Bancshares merger proposal in order for the merger to occur. If First Bancshares shareholders fail to approve the First Bancshares merger proposal, the merger will not occur.

If you fail to vote, mark “ABSTAIN” on your proxy card or fail to instruct your bank or broker how to vote with respect to the First Bancshares merger proposal, it will have the same effect as a vote “AGAINST” the proposal.

First Bancshares adjournment proposal. Approval of the First Bancshares adjournment proposal requires the affirmative vote of a majority of the shares present in person or by proxy at the meeting and entitled to vote on the proposal, whether or not a quorum is present. If First Bancshares shareholders fail to approve the First Bancshares adjournment proposal, but approve the First Bancshares merger proposal, the merger may nonetheless occur.

Because shares voted “ABSTAIN” are counted as present for purposes of determining a quorum, if you mark “ABSTAIN” on your proxy card, it will have the same effect as a vote “AGAINST” the First Bancshares adjournment proposal. If you fail to vote or fail to instruct your bank or broker how to vote with respect to the First Bancshares adjournment proposal, you will be deemed not to be present with respect to the proposal, and it will have no effect on the proposal.

What vote is required to approve each proposal at the HSBI special meeting?

HSBI merger proposal. Approval of the HSBI merger proposal requires the affirmative vote of a majority of the issued and outstanding shares of HSBI common stock entitled to vote. HSBI shareholders must approve the HSBI merger proposal in order for the merger to occur. If HSBI shareholders fail to approve the HSBI merger proposal, the merger will not occur.

If you fail to vote, mark “ABSTAIN” on your proxy card or fail to instruct your bank or broker how to vote with respect to the HSBI merger proposal, it will have the same effect as a vote “AGAINST” the proposal.

HSBI 280G proposal. Approval of the 280G proposal requires the affirmative vote of more than 75% of the voting power of the issued and outstanding shares of HSBI common stock entitled to vote (excluding shares held by Mr. Serff and certain related parties, collectively referred to as ineligible shareholders). Unlike the HSBI merger proposal, HSBI’s and Heritage Southeast Bank’s directors have not entered into any agreement to vote their shares in favor of the 280G proposal. If HSBI shareholders fail to vote, mark “ABSTAIN” on your proxy card or fail to instruct your bank or broker how to vote with respect to the 280G proposal, it will have the same effect as a vote “AGAINST” the 280G proposal.

HSBI adjournment proposal. Approval of the HSBI adjournment proposal requires the affirmative vote of a majority of the shares present in person or by proxy at the meeting and entitled to vote on the proposal, whether or not a quorum is present. If HSBI shareholders fail to approve the HSBI adjournment proposal, but approve the HSBI merger proposal, the merger may nonetheless occur.

Because shares voted “ABSTAIN” are counted as present for purposes of determining a quorum, if you mark “ABSTAIN” on your proxy card, it will have the same effect as a vote “AGAINST” the HSBI adjournment proposal. If you fail to vote or fail to instruct your bank or broker how to vote with respect to the HSBI adjournment proposal, you will be deemed not to be present with respect to the proposal, and it will have no effect on the proposal.

Will the payments to Brad Serff that are subject to the 280G proposal affect the amount of merger consideration to be paid to HSBI shareholders?

No. The outcome of the vote on the 280G proposal, whether approved or not, will not affect the amount of the merger consideration that an HSBI shareholder will receive if the merger is completed. In addition, approval of the 280G proposal is not a condition to the completion of the merger.

TABLE OF CONTENTS

What are the conditions to the completion of the merger?

The obligations of First Bancshares and HSBI to complete the merger are subject to the satisfaction or waiver of certain closing conditions contained in the merger agreement, including the receipt of required regulatory approvals and the expiration of all statutory waiting periods, the receipt of tax opinions, approval by First Bancshares shareholders of the First Bancshares merger proposal and approval by HSBI shareholders of the HSBI merger proposal.

While we expect the merger to be completed in the fourth quarter of 2022 or first quarter of 2023, because fulfillment of some of the conditions to completion of the merger are not entirely within our control, we cannot assure you of the actual timing.

How does the First Bancshares board of directors and the HSBI board of directors recommend that I vote?

First Bancshares. The First Bancshares board of directors has unanimously determined that the merger agreement, the merger and the other transactions contemplated by the merger agreement, including the issuance of shares of First Bancshares common stock in the merger, are advisable, fair to and in the best interests of First Bancshares and its shareholders and unanimously recommends that First Bancshares shareholders vote “FOR” the First Bancshares merger proposal and “FOR” the First Bancshares adjournment proposal.

TABLE OF CONTENTS

Are HSBI shareholders entitled to appraisal or dissenters’ rights?

Yes. HSBI shareholders may assert dissenters’ rights in connection with the merger and, upon complying with the requirements of the Georgia Business Corporation Code, which we refer to as the “GBCC,” which is the law under which HSBI is incorporated, receive cash in the amount of the “fair value” of their shares of HSBI common stock instead of the merger consideration. This “fair value” could be the same or more than the merger consideration but could also be less. See “The Merger — Dissenters’ Rights” on page 109. A copy of the applicable sections of the GBCC is attached as Annex E to this joint proxy statement/prospectus.

Are First Bancshares shareholders entitled to appraisal or dissenters’ rights?

No, under the Mississippi Business Corporation Act, which we refer to as the “MBCA,” which is the law under which First Bancshares is incorporated, the holders of First Bancshares common stock will not be entitled to any appraisal rights or dissenters’ rights in connection with the merger.

What are the U.S. federal income tax consequences of the merger to HSBI shareholders?

The merger is expected to qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended, which we refer to as the “Code.” HSBI shareholders are not expected to recognize any gain or loss for U.S. federal income tax purposes on the exchange of their shares of HSBI stock for shares of First Bancshares common stock pursuant to the merger. However, HSBI shareholders may recognize gain or loss if they exercise dissenters’ rights or if they receive any cash in lieu of a fractional share of First Bancshares common stock.

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

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

What happens if the merger is not completed?

If the merger is not completed, HSBI shareholders will not receive any consideration for their shares of HSBI common stock that otherwise would have been received in connection with the merger. Instead, HSBI will remain an independent private company. In addition, if the merger agreement is terminated, in certain circumstances, HSBI may be required to pay First Bancshares a fee with respect to such termination of the merger agreement. See “The Merger Agreement — Termination of the Merger Agreement” and “The Merger Agreement — Effect of Termination” beginning on pages 126 and 127. 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 HSBI stock.

What would happen if the 280G proposal is not approved by HSBI shareholders?

Mr. Serff has waived any compensatory payment above the safe harbor amount that he may be entitled to receive in connection with the merger if the approval of the 280G proposal is not obtained which would operate to limit such amounts payable to Mr. Serff to three times his “base amount” as determined in connection with Section 280G of the Code minus $1.00, which we refer to as the “waived amount.” If the HSBI shareholders do not approve the 280G proposal, then Mr. Serff will forfeit his waived amount and he will not receive or retain any portion of the waived amount.

What happens if I sell my shares after the applicable record date before my company’s special meeting of shareholders?

Each of the First Bancshares record date and HSBI record date is earlier than the date of the First Bancshares special meeting or HSBI special meeting, as applicable, and earlier than the date that the merger is expected to be completed. If you sell or otherwise transfer your shares of First Bancshares common stock or HSBI common stock, as applicable, after the applicable record date but before the date

TABLE OF CONTENTS

of the applicable shareholder meeting, you will retain your right to vote at such meeting (provided that such shares remain outstanding on the date of such meeting), but, with respect to HSBI common stock, you will not have the right to receive the merger consideration to be received by HSBI shareholders in connection with the merger. In order to receive the merger consideration, you must hold your shares of HSBI common stock through completion of the merger.

What do I do if I receive more than one joint proxy statement/prospectus or set of voting instructions?

First Bancshares shareholders and HSBI shareholders may receive more than one set of voting materials, including multiple copies of this joint proxy statement/prospectus and multiple proxy cards or voting instruction forms. For example, if you hold shares of First Bancshares or HSBI common stock in more than one brokerage account, you will receive a separate voting instruction form for each brokerage account in which you hold such shares. If you hold shares directly as a record holder and also in “street name” or otherwise through a nominee, you will receive more than one joint proxy statement/prospectus and/or set of voting instructions relating to the applicable shareholder meeting. These should each be voted and/or returned separately in order to ensure that all of your shares are voted.

Should HSBI shareholders send stock certificates with their proxy card?

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

Who will solicit proxies from First Bancshares and HSBI shareholders?

First Bancshares, HSBI and their respective directors, officers and employees may also solicit proxies by mail, telephone, facsimile, electronic mail or in person, but no additional compensation will be paid to them for such solicitation.

Do HSBI directors and executive officers have interests in the merger that are different from, or in addition to, the directors of other HSBI shareholders?

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

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

You are not required to take any specific actions to exchange your shares of HSBI stock if your shares are held in book-entry form. After the completion of the merger, shares of HSBI 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.

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

If you are unable to locate your original HSBI stock certificate(s), you should contact [•]. 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.

Whom should I call with questions?

The Merger

The Merger Agreement (page 112)

First Bancshares and HSBI entered into an Agreement and Plan of Merger, dated as of July 27, 2022, which we refer to as the merger agreement. The merger agreement governs the merger. The merger agreement is included in this joint proxy statement/prospectus as Annex A. All descriptions in this summary and elsewhere in this joint proxy statement/prospectus of the terms and conditions of the merger are qualified

TABLE OF CONTENTS

by reference to the merger agreement. Please read the merger agreement carefully for a more complete understanding of the merger.

The Merger (page 51)

Pursuant to the merger agreement, HSBI 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, Heritage Southeast Bank, a wholly owned banking subsidiary of HSBI, 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 113)

If the merger is completed, each share of HSBI common stock issued and outstanding immediately prior to the effective time of the merger (other than dissenters’ shares) will be converted into the right to receive 0.965, or the exchange ratio, of a share of First Bancshares common stock.

First Bancshares will not issue any fractional shares of First Bancshares common stock in the merger. Rather, HSBI shareholders who would otherwise be entitled to a fractional share of First Bancshares common stock upon the completion of the merger will instead receive cash (without interest and rounded to the nearest whole cent) in an amount equal to such fractional part of a share of First Bancshares common stock, rounded to the nearest one hundredth of a share, multiplied by the average of the daily volume weighted average price of First Bancshares common stock on the NASDAQ Global Market for the ten trading days ending on the trading day immediately prior to the determination date. The determination date is defined as the date that is five days prior to the closing of the merger.

The exchange ratio is fixed, which means that it will not change between now and the date of the merger, regardless of whether the market price of either shares of First Bancshares common stock or HSBI common stock changes. Therefore, the value of the merger consideration will depend on the market price of shares of First Bancshares common stock at the time HSBI shareholders receive shares of First Bancshares common stock in the merger. First Bancshares common stock is listed on NASDAQ under the symbol “FBMS,” and HSBI common stock is quoted on the OTCQX Market under the symbol “HSBI.”

The following table shows the closing sale prices of First Bancshares common stock and HSBI common stock as reported on NASDAQ and the OTCQX Market, respectively, on July 26, 2022, the last trading day before the public announcement of the merger agreement, and on [ ], 2022, the latest practicable

TABLE OF CONTENTS

trading day before the date of this joint proxy statement/prospectus. The table also shows the implied value of the merger consideration payable for each share of HSBI common stock, which we calculated by multiplying the closing price per share of First Bancshares common stock on those dates by the exchange ratio.

	First Bancshares Common Stock			HSBI Common Stock			Implied Value of One Share of First Bancshares Common Stock
July 26, 2022		$	29.68		$	21.70		$	28.64
[ ], 2022

The market price of shares of First Bancshares common stock has fluctuated since the date of the announcement of the merger agreement and will continue to fluctuate from the date of this joint proxy statement/prospectus to the date of the HSBI special meeting and the date the merger is completed and thereafter. The market price of shares of First Bancshares common stock when received by HSBI shareholders after the merger is completed could be greater than, less than or the same as the market price of shares of First Bancshares common stock on the date of this joint proxy statement/prospectus or at the time of the HSBI special meeting or any adjournment or postponement thereof.

Based on the exchange ratio and the number of shares of HSBI stock outstanding, the maximum number of shares of First Bancshares common stock offered by First Bancshares and issuable in the merger is 6,962,435.

Procedures for Converting Shares of HSBI Stock into Merger Consideration (page 114)

Promptly after the effective time of the merger, First Bancshares’ exchange agent will mail to each holder of record of HSBI stock that is converted into the right to receive the merger consideration a letter of transmittal and instructions for the surrender of the holder’s HSBI stock certificate(s) for the merger consideration (including cash in lieu of any fractional HSBI shares), and any dividends or distributions to which such holder is entitled to pursuant to the merger agreement.

Please do not send in your certificates until you receive these instructions.

The First Bancshares Special Meeting of Shareholders (page 42)

The special meeting of First Bancshares shareholders will be held on [ ], 2022, at [ ], Central time, at [ ]. At the First Bancshares special meeting, First Bancshares shareholders will be asked to:

•

approve the First Bancshares merger proposal; and

•

approve the First Bancshares adjournment proposal.

The First Bancshares board of directors has fixed the close of business on [ ], 2022 as the record date for determining the holders of First Bancshares common stock entitled to receive notice of, and to vote at, the First Bancshares special meeting. As of the First Bancshares record date, there were [ ] shares of First Bancshares common stock outstanding and entitled to vote at the First Bancshares special meeting held by [ ] holders of record.

Each share of First Bancshares common stock entitles the holder thereof to one vote on each proposal to be considered at the First Bancshares special meeting. As of the First Bancshares record date, directors and executive officers of First Bancshares and their affiliates owned and were entitled to vote [ ] shares of First Bancshares common stock, representing approximately [ ]% of the shares of

TABLE OF CONTENTS

First Bancshares common stock issued and outstanding on that date. As of the First Bancshares record date, there were [ ] shares of First Bancshares common stock, representing approximately [ ]% of the shares of First Bancshares common stock issued and outstanding on that date, subject to First Bancshares voting agreements.

As of the First Bancshares record date, HSBI did not beneficially hold any shares of First Bancshares common stock.

The affirmative vote of a majority of the outstanding shares of First Bancshares common stock must vote in favor of the proposal to approve the merger agreement. If you vote to “ABSTAIN” with respect to the merger proposal or if you fail to vote on the merger proposal, this will have the same effect as voting “AGAINST” the merger proposal.

The adjournment proposal will be approved if the votes of First Bancshares common stock cast in favor of the adjournment proposal exceed the votes cast against the adjournment proposal. If you vote to “ABSTAIN” with respect to the adjournment proposal or if you fail to vote on the adjournment proposal, this will have no effect on the outcome of the vote on the adjournment proposal.

Each share of First Bancshares stock entitled the holder thereof as of the record date for the First Bancshares special meeting to one vote at the First Bancshares special meeting on all matters properly presented at the meeting.

The HSBI Special Meeting of Shareholders (page 47)

The special meeting of HSBI shareholders will be held on [ ], 2022, at [ ]:00 a.m., local time, at [ ]. At the HSBI special meeting, HSBI shareholders will be asked to:

•

approve the HSBI merger proposal;

•

approve the 280G proposal; and

•

approve the HSBI adjournment proposal.

Only holders of record at the close of business on [ ], 2022, the HSBI record date, will be entitled to vote at the HSBI special meeting. Each outstanding share of HSBI stock is entitled to one vote on each proposal to be considered at the HSBI special meeting (except that shares held by Mr. Serff and certain related parties will not count toward approval of the 280G proposal). As of the HSBI record date, there were [ ] shares of HSBI common stock entitled to vote at the HSBI special meeting. All directors of HSBI and Heritage Southeast Bank have entered into voting agreements with First Bancshares, pursuant to which they have agreed, solely in their capacity as HSBI shareholders, to vote all of their shares of HSBI stock in favor of the proposals to be presented at the HSBI special meeting. As of the HSBI record date, the directors and their affiliates who are parties to the voting agreements owned and were entitled to vote an aggregate of approximately [ ] shares of HSBI common stock, which represented approximately [ ]% of the shares of HSBI common stock outstanding on that date. As of the HSBI record date, the directors and executive officers of HSBI, Heritage Southeast Bank and their affiliates beneficially owned and were entitled to approximately [ ] shares of HSBI common stock, which represented approximately [ ]% of the shares of HSBI common stock outstanding on that date. As of the HSBI record date, First Bancshares did not own or have the right to vote any of the outstanding shares of HSBI stock.

The affirmative vote of a majority of the outstanding shares of HSBI common stock must vote in favor of the HSBI merger proposal. If you vote to “ABSTAIN” with respect to the HSBI merger proposal or if you fail to vote on the HSBI merger proposal, this will have the same effect as voting “AGAINST” the HSBI merger proposal.

In order to approve the 280G proposal, the holders of more than 75% of the voting power of the outstanding shares of HSBI common stock (excluding shares held by Mr. Serff and certain related parties) must vote in favor of the 280G proposal. If you vote to “ABSTAIN” with respect to the 280G proposal or if you fail to vote on the 280G proposal, this will have the same effect as voting “AGAINST” the 280G proposal.

TABLE OF CONTENTS

The HSBI adjournment proposal will be approved if the votes of HSBI common stock cast in favor of the HSBI adjournment proposal exceed the votes cast against the HSBI adjournment proposal. If you vote to “ABSTAIN” with respect to the HSBI adjournment proposal or if you fail to vote on the HSBI adjournment proposal, this will have no effect on the outcome of the vote on the HSBI adjournment proposal.

Each share of HSBI common stock you own as of the record date for the HSBI special meeting entitles you to one vote at the HSBI special meeting on all matters properly presented at the meeting.

Recommendation of the First Bancshares Board of Directors (page 42)

The First Bancshares board of directors has unanimously determined that the merger agreement, the merger and the other transactions contemplated by the merger agreement, including the issuance of shares of First Bancshares common stock to holders of HSBI Common stock in connection with the merger, are advisable, fair to and in the best interests of First Bancshares and its shareholders and unanimously recommends that First Bancshares shareholders vote “FOR” the First Bancshares merger proposal and “FOR” the First Bancshares adjournment proposal. For a more detailed discussion of the First Bancshares board of directors’ recommendation, see “The Merger — First Bancshares’ Reasons for the Merger and Recommendations of the First Bancshares Board of Directors” beginning on page 56.

Recommendation of the HSBI Board of Directors (page 47)

HSBI’s board of directors has unanimously determined that the merger agreement, the merger and the other transactions contemplated by the merger agreement are advisable, fair to and in the best interests of HSBI and its shareholders and unanimously recommends that HSBI shareholders vote “FOR” the HSBI merger proposal, “FOR” the 280G proposal, and “FOR” the HSBI adjournment proposal. See “The Merger — HSBI’s Reasons for the Merger and Recommendations of the HSBI Board of Directors beginning on page 57.”

Board Composition and Management of First Bancshares after the Merger (page 101)

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. First Bancshares has also agreed to evaluate and consider the current directorate of HSBI in good faith, and, upon completion of such evaluation, consider expanding the board of directors of First Bancshares by one position and appointing one current member of the board of directors of HSBI to serve as a director of First Bancshares following the merger.

Interests of HSBI Directors and Executive Officers in the Merger (page 101)

HSBI shareholders should be aware that HSBI’s directors and executive officers have interests in the merger and have arrangements that are different from, or in addition to, those of HSBI shareholders generally. These interests and arrangements may create potential conflicts of interest. HSBI’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 HSBI shareholders vote in favor of the HSBI merger proposal.

These interests include:

•

cash payments to be made to five executive officers who have employment agreements with HSBI and Heritage Southeast Bank in return for the termination of those employment agreements;

•

new employment agreements offered by First Bancshares and the First Bank to four executive officers;

•

a cash payment to be made to four executive officers who have a cash-based supplemental executive retirement benefit agreement (“SERP”) with Heritage Southeast Bank, and a cash and stock payment to one executive officer who has a cash-and-stock-based SERP agreement with Heritage Southeast Bank;

TABLE OF CONTENTS

•

the accelerated vesting of equity awards issued to certain directors and executive officers and cash payments to be made to holders of options to purchase HSBI common stock; and

•

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

For a more complete description of these interests, see “The Merger — Interests of HSBI Directors and Executive Officers in the Merger” and “The Merger Agreement — Indemnification and Directors’ and Officers’ Insurance.”

Dissenters’ Rights in the Merger (page 109)

Pursuant to Article 13 of the Georgia Business Corporation Code (the “GBCC”), a holder of record of HSBI stock who objects to the proposed merger and who fully complies with all of the provisions of Article 13 of the GBCC (but not otherwise) shall be entitled to demand and receive payment of “fair value” for all (but generally not less than all) of his or her shares of HSBI stock if the proposed merger is consummated, as determined by a Georgia court of law. Under the GBCC, the “fair value” of HSBI stock is the “the value of the shares immediately before the effectuation of the corporate action to which the dissenter objects, excluding any appreciation or depreciation in anticipation of the corporate action.” The closing price per share of HSBI common stock was $21.70 on July 26, 2022, the last full trading day prior to announcement of the proposed merger, and the closing price per share of HSBI common stock was $[ ] on [ ], the latest practicable day before the printing of this proxy statement/prospectus. In determining the “fair value” of HSBI shares immediately before the effectuation of the proposed merger with First Bancshares, management of HSBI believes that the fair value of HSBI shares would be between these trading prices.

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

Conditions to Completion of the Merger (page 125)

Currently, First Bancshares and HSBI expect to complete the merger in the fourth quarter of 2022 or first quarter of 2023. As more fully described in this joint 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 HSBI common stock;

•

approval of the merger agreement by the holders of at least a majority of the outstanding shares of First Bancshares common stock;

•

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 joint 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 the merger is expected to qualify as a “reorganization” within the meaning of Section 368(a) of the Code;

•

the shares of First Bancshares common stock to be issued to holders of HSBI stock being approved for listing on the NASDAQ Global Market;

•

less than 10% of the issued and outstanding shares of HSBI stock exercising dissenters’ rights;

•

the receipt of certain consents and approval from third parties; and

•

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

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

TABLE OF CONTENTS

Regulatory Approvals Required for the Merger (page 104)

Both First Bancshares and HSBI 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 Mississippi Department of Banking and Consumer Finance, or the Mississippi Department, 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 intends to submit all applications, waiver requests and notifications to obtain the required regulatory approvals. Although neither First Bancshares nor HSBI knows of any reason why these regulatory approvals cannot be obtained, First Bancshares and HSBI 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.

No Solicitation (page 123)

Under the merger agreement, HSBI 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 HSBI 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 HSBI 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 HSBI’s required shareholder approval, HSBI 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). HSBI must notify First Bancshares promptly (but in no event later than 48 hours) after the receipt of such acquisition proposal.

Additionally, prior to obtaining HSBI’s required shareholder approval, HSBI 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 would reasonably be expected to cause it to violate its fiduciary duties to HSBI’s shareholders under applicable law. However, HSBI 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 127)

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 April 30, 2023, subject to automatic extension to July 31, 2023 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 HSBI is not obtained at a meeting at which a vote was taken; or

TABLE OF CONTENTS

•

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

•

if HSBI 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);

•

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

•

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

•

if HSBI fails to publicly recommend against a publicly announced acquisition proposal within three business days of being requested to do so by First Bancshares or fails to publicly reconfirm its recommendation to its shareholders within three business days of being requested to do so by First Bancshares; or

•

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

In addition, HSBI may terminate the merger agreement if:

•

HSBI’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 HSBI pays to First Bancshares an $8,000,000 termination fee;

•

First Bancshares materially breaches its obligations to properly call, give notice of, and commence a meeting of shareholders to vote on the merger or if the board of directors of First Bancshares fails to recommend that the shareholders of First Bancshares approve the merger and issuance of shares of First Bancshares common stock in connection with the merger; 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 $23.74, and (ii) the decline in the price of First Bancshares common stock (as measured by the average closing price divided by $29.68) 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 $116.02); provided, however, that First Bancshares has the option, but not the obligation, to adjust the exchange ratio to prevent the termination of merger agreement.

Termination Fee (page 127)

If the merger agreement is terminated under certain circumstances, including circumstances involving a change in recommendation by HSBI’s board of directors, HSBI may be required to pay First Bancshares a termination fee of $8,000,000. The termination fee could discourage other companies from seeking to acquire or merge with HSBI.

Expenses (page 127)

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 of the Merger (page 105)

The merger is expected to qualify as a “reorganization” within the meaning of Section 368(a) of the Code. It is a condition to the respective obligations of First Bancshares and HSBI to complete the merger

TABLE OF CONTENTS

that each of First Bancshares and HSBI receives a tax opinion from its respective outside legal counsel, dated as of the closing date of the merger, to that effect. Based upon a qualification of the merger as a reorganization under the Code, holders of HSBI stock who exchange their shares of HSBI stock for shares of First Bancshares common stock generally will not recognize gain or loss with respect to the receipt of First Bancshares common stock in the merger. Holders of HSBI stock generally will be subject to tax with respect to any cash consideration received, including cash received instead of fractional shares of First Bancshares common stock. For further information, see “The Merger — Material U.S. Federal Income Tax Consequences of the Merger.”

Accounting Treatment of the Merger (page 108)

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.

The Rights of Holders of HSBI Common Stock Will Change as a Result of the Merger (see page 159)

The rights of holders of HSBI common stock are governed by Georgia law, as well as HSBI’s Articles of Incorporation (which we refer to as the HSBI articles), and HSBI’s Bylaws, as amended (which we refer to as the “HSBI bylaws”). After completion of the merger, the rights of former HSBI 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”).

The material differences between the organizational documents and the rights of shareholders of HSBI and shareholders of First Bancshares are explained under the section “Comparison of Rights of First Bancshares shareholders and HSBI shareholders” beginning on page 159.

Opinion of HSBI’s Financial Advisor (page 60 and Annex B)

Piper Sandler & Co., which we refer to as Piper Sandler, HSBI’s financial advisor, delivered its opinion, dated July 26, 2022, to HSBI’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 HSBI.

The full text of the written opinion of Piper Sandler, which sets forth the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by Piper Sandler in connection with its opinion, is attached as Annex B to this joint proxy statement/prospectus. Piper Sandler’s opinion was for the information of, and directed to, HSBI’s board of directors (in its capacity as such) in connection with its consideration of the financial terms of the merger. Piper Sandler’s opinion is not a recommendation as to how any holder of HSBI’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 HSBI to engage in the merger, the relative merits of the merger as compared to any other alternative business strategies that might exist for HSBI or the effect of any other transaction in which HSBI might engage.

Opinions of First Bancshares’ Financial Advisors (page 70, Annex C and Annex D)

Opinion of Keefe, Bruyette & Woods, Inc. In connection with the merger, Keefe, Bruyette & Woods, Inc. ( “KBW”) delivered a written opinion, dated July 27, 2022, to the First Bancshares board of directors as to the fairness, from a financial point of view and as of the date of the opinion, to First Bancshares of the exchange ratio in the proposed merger. The full text of KBW’s opinion, which describes the procedures followed, assumptions made, matters considered, and qualifications and limitations on the review undertaken by KBW in preparing the opinion, is attached Annex C to this joint proxy statement/prospectus. The

opinion was for the information of, and was directed to, the First Bancshares board of directors (in its capacity as such) in connection with its consideration of the financial terms of the merger. The opinion did not address the underlying business decision of First Bancshares to engage in the merger or enter into the merger agreement or constitute a recommendation to the First Bancshares board of directors in connection with the merger, and it does not constitute a recommendation to any holder of First Bancshares common stock or any shareholder of any other entity as to how to vote in connection with the merger or any other matter.

Opinion of D.A. Davidson & Co. In connection with the merger, D.A. Davidson & Co., which we refer to as D.A. Davidson, delivered a written opinion, dated July 27, 2022, to the First Bancshares board of directors as to the fairness, from a financial point of view and as of the date of the opinion, to First Bancshares of the merger consideration to be paid by First Bancshares in the proposed merger. The full text of D.A. Davidson’s opinion, which describes the procedures followed, assumptions made, matters considered, and qualifications and limitations on the review undertaken by D.A. Davidson in preparing the opinion, is attached as Annex D to this joint proxy statement/prospectus. The opinion is directed only to First Bancshares’ board of directors and addresses only the fairness, from a financial point of view, to First Bancshares of the Merger Consideration. D.A. Davidson does not express any view on, and its opinion does not address, any other term or aspect of the Agreement or Merger (including, without limitation, the form or structure of the Merger) or any term or aspect of any other agreement or instrument contemplated by the Agreement or entered into in connection with the Merger, or as to the underlying business decision by First Bancshares to engage in the Merger.

For further information, please see the section entitled “The Merger — Opinions of First Bancshares’s Financial Advisors” beginning on page 70.

Closing and Effective Time of the Merger (see page 112)

The closing date is currently expected to occur in the fourth quarter of 2022 or the first quarter of 2023. 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 HSBI 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 shareholder approvals will be received.

TABLE OF CONTENTS

UNAUDITED PRO FORMA COMBINED CONSOLIDATED FINANCIAL INFORMATION

The following unaudited pro forma combined financial information is presented to illustrate the estimated effects of the merger based on the historical financial statements and accounting records of First Bancshares and HSBI after giving effect to the merger, including the merger-related pro forma adjustments as described in the notes below. The unaudited pro forma combined condensed consolidated financial information has been prepared using the acquisition method of accounting. Under this method, HSBI’s assets and liabilities as of the date of the acquisition will be recorded at their respective fair values and added to those of First Bancshares. Any difference between the purchase price for HSBI and the fair value of the identifiable net assets acquired (including core deposit intangibles) will be recorded as goodwill. The goodwill resulting from the acquisition will not be amortized to expense, but instead will be reviewed for impairment at least annually. Any core deposit intangible and other intangible assets with estimated useful lives to be recorded by First Bancshares in connection with the acquisition will be amortized to expense over their estimated useful lives. The financial statements of First Bancshares issued after the acquisition will reflect the results attributable to the acquired operations of HSBI beginning on the date of completion of the acquisition.

If the merger is completed, each share of HSBI common stock issued and outstanding immediately prior to the effective time of the merger (except for owned by First Bancshares or HSBI, in each case, other than shares held on behalf of third parties or as a result of debts previously contracted, and shares held by HSBI shareholders who properly exercise dissenters’ rights) will be converted into the right to receive 0.965, or the exchange ratio, of a share of First Bancshares common stock. All stock options awarded under the HSBI equity plans will fully vest at the closing of the merger and will be converted automatically into the right to receive an amount of cash equal to the product of (i) the excess, if any, of (A) the product of (x) the exchange ratio multiplied by (y) $29.68 (representing the closing price of the First Bancshares’ common stock on the last trading day prior to the signing of the Merger Agreement), over (ii) the per share exercise price of the option to acquire shares of HSBI common stock prior to the effective time of the merger, multiplied by (B) the number of shares of HSBI common stock subject to such option prior to the effective time of the merger, rounding up to the nearest cent. The merger agreement also provides that outstanding and unvested restricted shares of HSBI common stock pursuant to its equity plans will fully vest at the closing of the merger and automatically be converted into the right to receive the merger consideration.

The estimated purchase price for the merger is $214.1 million in the aggregate based upon the closing price per share of First Bancshares common stock of $30.66 on July 27, the date of the merger agreement. The transaction is expected to close during the fourth quarter of 2022 or first quarter of 2023, subject to the receipt of First Bancshares and HSBI shareholder approval, regulatory approvals and other customary closing conditions.

As further detailed in the notes below, effective August 1, 2022, First Bancshares acquired Beach Bancorp, Inc., which we refer to as BBI, pursuant to the merger of BBI with and into First Bancshares, which we refer to as the BBI merger. The financial condition and operating results of BBI are presented on a pro forma basis with the historical results of First Bancshares for purposes of the following unaudited pro forma combined financial information.

The unaudited pro forma combined consolidated balance sheet as of June 30, 2022 is presented as if the HSBI merger and BBI merger had been consummated on June 30, 2022. The unaudited pro forma combined consolidated statements of income for the year ended December 31, 2021 and for the six month

TABLE OF CONTENTS

period ended June 30, 2022 are presented as if the HSBI merger and BBI merger had been consummated occurred on January 1, 2021. The historical combined condensed financial information has been adjusted to reflect factually supportable items that are directly attributable to the BBI merger and the HSBI merger and, with respect to the income statement only,

The historical consolidated financial information has been adjusted in the unaudited pro forma combined condensed financial information to give effect to the pro forma events that are (i) directly related to the HSBI merger and BBI, (ii) factually supportable and (iii) with respect to the unaudited pro forma combined condensed statement of income, expected to have a continuing effect on the results of the combined company. The unaudited pro forma combined condensed financial information contained herein does not reflect the costs of any integration activities or benefits that may result from the realization of future cost savings from operating efficiencies, or any other synergies that may result from the merger. The following unaudited pro forma combined condensed financial information gives effect to the merger and includes adjustments for the following:

•

certain reclassifications to conform historical financial statement presentations between the companies; and

•

application of the acquisition method of accounting under the provisions of topic ASC 805, “Business Combinations,” to reflect merger consideration of approximately $214.1 million in exchange for all outstanding shares of First Bancshares common stock.

Future results may differ materially from the results reflected because of various factors, including those discussed in the section entitled “Risk Factors” beginning on page 35 and appearing under the caption “Risk Factors” in First Bancshares’ most recently filed Annual Reports on Form 10-K and in any subsequently filed Quarterly Reports on Form 10-Q or Current Reports on Form 8-K, which are incorporated by reference in this proxy statement/prospectus, and the factors discussed in the section entitled “Cautionary Statement Regarding Forward-Looking Statements” beginning on page 21. Among other factors, the actual amounts recorded as of the completion of the merger may differ materially from the information presented in these unaudited pro forma combined condensed financial statements as a result of:

•

net cash used or generated in First Bancshares’ or HSBI’s operations between the signing of the merger agreement and the completion of the merger;

•

the timing of the completion of the merger, changes in total merger-related expenses, and integration costs, including costs associated with systems implementation, severance, and other costs related to exit or disposal activities;

•

other changes in First Bancshares’ or HSBI’s net assets that occur prior to the completion of the merger, which could cause material differences in the information presented below; and

•

changes in the financial results of the combined company.

The risk of such variance is particularly significant with respect to the preliminary purchase price allocation, because such allocation is based, in large part, on the closing price per share of First Bancshares’ common stock as of the closing date. The preliminary purchase price allocation reflected in the unaudited pro forma combined condensed financial information assumes a closing price per share of First Bancshares’ common stock of $30.66, the closing price of First Bancshares common stock on July 27, 2022. The financial markets experience volatility due in part to national and global events and has contributed to fluctuations in the trading price of First Bancshares common stock and HSBI common stock. Continued financial market volatility, and its effect on the trading prices of First Bancshares common stock and HSBI common stock, will largely depend on future developments, which First Bancshares and HSBI cannot accurately predict or control. Given this volatility and uncertainty, the unaudited pro forma combined condensed financial information included in this proxy statement/prospectus may not be indicative of and does not purport to represent the combined company’s actual financial condition or results of operations as of the closing date or any future or other date or period.

The following unaudited pro forma combined condensed financial information and related notes are being provided for illustrative purposes only and do not purport to represent what the combined company’s actual results of operations or financial position would have been had the merger been completed on the

TABLE OF CONTENTS

dates indicated, nor are they necessarily indicative of the combined company’s future results of operations or financial position for any future period. The preparation of the unaudited pro forma combined condensed financial statements and related adjustments required management to make certain assumptions and estimates. expected to have a continuing impact on consolidated results of operations.

The unaudited pro forma combined consolidated financial statements should be read together with:

•

The accompanying notes to the unaudited pro forma combined consolidated financial statements;

•

First Bancshares’ unaudited consolidated financial statements and accompanying notes as of and for the six months ended June 30, 2022, included in First Bancshares’ Quarterly Report on Form 10-Q for the six months ended June 30, 2022, which is incorporated by reference into this proxy statement/prospectus;

•

First Bancshares’ audited consolidated financial statements and accompanying notes as of and for the year ended December 31, 2021, included in First Bancshares’ Annual Report on Form 10-K for the year ended December 31, 2021, which is incorporated by reference into this proxy statement/prospectus;

•

HSBI’s unaudited consolidated financial statements and accompanying notes as of and for the six months ended June 30, 2022, beginning on page 26 in this proxy statement/prospectus; and

HSBI’s audited consolidated financial statements and accompanying notes as of the year ended December 31, 2021, are attached as Annex F to this proxy statement/prospectus.

NOTES TO UNAUDITED PRO FORMA COMBINED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(all amounts are in thousands, except per share data, unless otherwise indicated)

Note 1 — Basis of Presentation

The unaudited pro forma condensed combined financial information included herein has been prepared pursuant to the rules and regulations of the SEC. Certain information and certain footnote disclosures normally included in financial statements prepared in accordance with GAAP have been omitted pursuant to such rules and regulations. However, management believes that the disclosures are adequate to make the information presented not misleading.

Note 2 — BBI Acquisition

On August 1, 2022, First Bancshares completed its acquisition of Beach Bancorp, Inc. (“BBI”) pursuant to an Agreement and Plan of Merger dated April 26, 2022 by and between First Bancshares and BBI (the “BBI Merger Agreement”). Upon the completion of the merger of BBI with and into the First Bancshares, Beach Bank, BBI’s wholly-owned subsidiary, was merged with and into The First Bank. Under the terms of the BBI Merger Agreement, each share of BBI common stock and each share of BBI preferred stock was converted into the right to receive 0.1711 of a share of Company common stock (the “BBI Exchange Ratio”), and all stock options awarded under the BBI equity plans were converted automatically into an option to purchase shares of Company common stock on the same terms and conditions as applicable to each such BBI option as in effect immediately prior to the effective time, with the number of shares underlying each such option and the applicable exercise price adjusted based on the BBI Exchange Ratio. First Bancshares paid consideration of approximately $101.5 million to the former BBI shareholders including 3,498,936 shares of the Company’s common stock and approximately $1 thousand in cash in lieu of fractional shares, and also assumed options entitling the owners thereof to purchase an additional 310,427 shares of the Company’s common stock. The acquisition of BBI does not constitute a business acquisition at the significance level that would require the filing of financial statements as contemplated by Rule 3-05 of Regulation S-X.

Note 3 — HSBI Acquisition

Under the terms of the merger agreement, holders of HSBI common stock have the right to receive a fixed exchange ratio of 0.965 shares of First Bancshares common stock for each share of HSBI common stock. For purposes of the unaudited pro forma combined condensed balance sheet, the estimated merger consideration is based on the total number of shares of HSBI common stock issued and outstanding as of June 30, 2022, [•] shares of HSBI common stock issuable under SERP agreements, and the closing price per share of First Bancshares common stock of $30.66 on July 27, the date of the merger agreement. The preliminary purchase price also takes into consideration the amount of cash that would be paid to holders stock options issued under HSBI equity plans, and the acceleration of vesting of any unvested restricted shares of HSBI common stock.

The following table summarizes the preliminary purchase price allocation to the estimated fair value of assets and liabilities of HSBI (in thousands, except per share data):

HSBI common shares outstanding as of June 30, 2022		7,020,849
HSBI common shares issuable under HSBI SERP Agreements		194,110
Price per share, based upon First Bancshares’ price of $30.66 on July 27, 2022		29.59
Total pro forma purchase price from common stock		213,490,637
Consideration to be paid to holders of HSBI options		647,914
Total Pro Forma Purchase Price	$	214,138,551

values. First Bancshares has not completed the valuation analysis and calculations in sufficient detail necessary to arrive at the required estimates of the fair market value of the HSBI assets to be acquired or liabilities assumed, other than a preliminary estimate for intangible assets and certain financial assets and financial liabilities. Accordingly, apart from the aforementioned, certain assets acquired and liabilities assumed are presented at their respective carrying amounts and should be treated as preliminary values. The fair value assessments are preliminary and are based upon available information and certain assumptions, which First Bancshares believes are reasonable under the circumstances. Actual results may differ materially from the assumptions within the unaudited pro forma combined condensed financial statements.

The following table sets forth a preliminary allocation of the estimated merger consideration to the fair value of the identifiable tangible and intangible assets acquired and liabilities assumed of HSBI using HSBI’s unaudited consolidated balance sheet as of June 30, 2022 (in thousands):

Preliminary Purchase Price:
Cash paid and value of stock issued			$	214,138
Identifiable Assets
Cash and due from banks	$	298,424
Securities, FHLB Stock and FNBB Stock		193,809
Loans (net), leases, and interest receivable		1,082,683
Core Deposit Intangible		25,909

RISK FACTORS

An investment in First Bancshares common stock in connection with the merger involves risks. In addition to the other information contained in or incorporated by reference into this joint proxy statement/prospectus, including the risk factors included in First Bancshares’ Annual Report on Form 10-K for the year ended December 31, 2021, you should carefully consider the following risk factors in deciding whether to vote to approve the merger agreement. You should keep these risk factors in mind when you read forward-looking statements in this document and in the documents incorporated by reference into this document. Please refer to the section of this joint proxy statement/prospectus titled “Special Cautionary Note Regarding Forward-Looking Statements.” You should also consider the other information in this document and the other documents incorporated by reference into this document. Please see the sections entitled “Additional Information” in the forepart of this document and “Where You Can Find More Information” beginning on page 175

Risks Related to the Merger

Because of the fixed exchange ratio and the fluctuation of the market price of First Bancshares common stock, HSBI 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 HSBI stock issued and outstanding immediately prior to the effective time of the merger will be converted into the right to receive 0.965 shares of First Bancshares common stock.

The market value of the merger consideration may vary from the market value on the date HSBI and First Bancshares announced the merger, on the date that this joint proxy statement/prospectus is mailed, on the date of the HSBI 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 joint proxy statement/prospectus will change the value of the shares of First Bancshares common stock that HSBI shareholders may receive. Stock price changes may result from a variety of factors that are beyond the control of First Bancshares and HSBI, 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 HSBI special meeting, HSBI shareholders will not know the precise market value of the merger consideration they may receive at the effective time of the merger. In addition, HSBI shareholders will not know the exact exchange ratio at the time of the HSBI special meeting, as it may be adjusted as a result of the measurement price. HSBI shareholders should obtain current sale prices for shares of First Bancshares common stock before voting their shares at the HSBI special meeting.

The merger may not be consummated unless important conditions are satisfied.

First Bancshares and HSBI expect the merger to close as early as the fourth quarter of 2022, but the acquisition is subject to the satisfaction of a number of closing conditions. Satisfaction of many of these conditions is beyond First Bancshares’ and HSBI’s control. If these conditions are not satisfied or waived, the merger will not be completed or may be delayed and each of First Bancshares and HSBI may lose some or all of the intended benefits of the merger. Certain of the conditions that remain to be satisfied include, but are not limited to:

•

the approval of the merger agreement and merger by the requisite vote of First Bancshares shareholders and HSBI shareholders;

•

the receipt of required regulatory approvals or waivers, including the approval or waiver from the Federal Reserve, Mississippi Department, and Georgia Department which are necessary to consummate the merger and the expiration of all statutory waiting periods without the imposition of any burdensome condition;

•

the absence of any injunction, order or decree restraining, enjoining or otherwise prohibiting the merger or any of the other transactions contemplated by the merger agreement or making the completion of the merger illegal;

TABLE OF CONTENTS

•

the effectiveness under the Securities Act of the registration statement on Form S-4 of which this joint proxy statement/prospectus is a part, and the absence of the issuance of a stop order or the initiation or threat by the SEC of proceedings for that purpose;

•

the receipt of all required consents and approvals identified by the merger agreement;

•

each party’s receipt of a tax opinion from its respective outside legal counsel, dated the closing date of the merger, to the effect that the merger qualifies as a “reorganization” within the meaning of Section 368(a) of the Code;

•

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

•

the absence of 10% or more of the outstanding shares of HSBI’s common stock exercising their dissenters’ right;

•

the absence of any material adverse effect in the financial condition, business or results of operations of HSBI, Heritage State Bank, First Bancshares, or The First;

•

the shares of First Bancshares common stock being approved for listing on the Nasdaq Stock Market;

•

the continued accuracy of the representations and warranties made by the parties in the merger agreement; and

•

the performance by each party of its respective obligations under the merger agreement.

As a result, the merger may not close as scheduled or at all. In addition, either First Bancshares or HSBI may terminate the merger agreement under certain circumstances. For additional information regarding the conditions to the merger, see “The Merger Agreement — Conditions to Complete the Merger” beginning on page 125.

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

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

•

HSBI being required, under certain circumstances, to pay to First Bancshares a termination fee equal to $8,000,000;

•

substantial costs incurred by HSBI 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

•

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 HSBI stock.

HSBI 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 HSBI. These uncertainties may impair HSBI’s ability to attract, retain and motivate key personnel until the merger is completed, and could cause customers and others that deal with HSBI to seek to change existing

TABLE OF CONTENTS

business relationships with HSBI. Retention of certain employees by HSBI may be challenging while the merger is pending, as certain employees may experience uncertainty about their future roles with HSBI 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 HSBI or First Bancshares, HSBI’s business or the business assumed by First Bancshares following the merger could be harmed. In addition, HSBI 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 HSBI.

The merger agreement limits HSBI’s ability to pursue an alternative acquisition proposal and requires HSBI to pay a termination fee of $8,000,000 under limited circumstances relating to alternative acquisition proposals.

Under the merger agreement, HSBI 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 123. The merger agreement also provides for HSBI to pay to First Bancshares a termination fee in the amount of $8,000,000 in the event that the merger agreement is terminated for certain reasons. See “The Merger Agreement — Termination Fee” on page 127. These provisions could discourage a potential competing acquirer that might have an interest in acquiring HSBI 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 HSBI 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 April 30, 2023 (subject to automatic extension to July 31, 2023 if the only outstanding condition to closing is the receipt of regulatory approvals), and the right of HSBI to terminate the merger agreement, subject to certain conditions, to accept a business combination transaction deemed to be superior to the merger by the HSBI board of directors. Additionally, HSBI 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 $23.74, and (ii) the decline in the price of First Bancshares common stock (as measured by the average closing price divided by $29.68) 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 $116.02); provided, however, that First Bancshares has the option, but not the obligation, to adjust the exchange ratio to prevent the termination of merger agreement.

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

First Bancshares and HSBI 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 HSBI 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 HSBI, 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 HSBI may evaluate the materiality of any such waiver to determine whether amendment of this joint proxy statement/prospectus and re-solicitation of proxies are necessary. First Bancshares and HSBI, 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

TABLE OF CONTENTS

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 Mississippi Department, the Georgia Department, 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 HSBI, 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 104.

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

The directors and executive officers of HSBI have arrangements that provide them with interests in the merger that are different from, or in addition to, those of the shareholders of HSBI generally. These interests and arrangements may create potential conflicts of interest and may influence or may have influenced the directors and executive officers of HSBI to support or approve the merger and the merger agreement. See “The Merger — Interests of HSBI Directors and Executive Officers in the Merger” beginning on page 101.

The opinions delivered to the respective boards of directors of First Bancshares and HSBI by the parties’ respective financial advisors prior to the execution of the merger agreement will not reflect changes in circumstances since the date of such opinions.

The First Bancshares board of directors received a separate fairness opinion from each of KBW and D.A. Davidson, which was delivered on, and dated, July 27, 2022, and the HSBI board of directors received a fairness opinion from Piper Sandler, which was delivered on, and dated, July 27, 2022. Changes in the operations and prospects of First Bancshares and HSBI, general market and economic conditions and other factors that may be beyond the control of First Bancshares and HSBI may alter the value of First Bancshares or HSBI or the prices of shares of First Bancshares common stock or HSBI common stock by the time the merger is completed. The opinions do not speak as of the time the merger is completed or as of any date other than the date of the opinions. Copies of the Piper Sandler, KBW, and D.A. Davidson fairness opinions are included as Annex B, Annex C, and Annex D, respectively, to this joint proxy statement/prospectus. For a description of the opinions that First Bancshares received from its financial advisors, please refer to “The Merger — Opinions of First Bancshares’ Financial Advisors” beginning on page 70. For a description of the opinion that HSBI received from its financial advisor, please refer to “The Merger — Opinion of HSBI’s Financial Advisor” beginning on page 60.

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

In general, either First Bancshares or HSBI 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 HSBI would not prevent the merger from going forward, even if the change or occurrence would have adverse effects on First Bancshares or HSBI, 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;

TABLE OF CONTENTS

•

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 HSBI or 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, HSBI 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 $[•] 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

•

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.

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 HSBI shareholders may file putative class action lawsuits against the boards of directors of First Bancshares and/or HSBI. 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 HSBI. 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 HSBI and First Bancshares. Although First Bancshares and HSBI 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 HSBI’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

TABLE OF CONTENTS

from certain synergies, including cost savings, the combined company may encounter potential difficulties in the integration process, including:

•

the inability to successfully combine HSBI’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. Following the execution of the merger agreement, First Bancshares offered employment agreements with certain key employees of HSBI, the effectiveness of which are conditioned upon 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 HSBI or First Bancshares or, following the merger, the combined company will be able to retain key employees.

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

The merger will result in HSBI shareholders having an ownership stake in the combined company that is smaller than their current stake in HSBI. Upon completion of the merger of HSBI with First Bancshares, we estimate that HSBI shareholders will own approximately [•]% of the issued and outstanding shares of common stock of the combined company. Consequently, HSBI 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 HSBI.

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 HSBI’s results of operations and the market prices of shares of First Bancshares common stock. Accordingly, the historical financial results of First Bancshares and HSBI and the historical

TABLE OF CONTENTS

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 HSBI and certain risks to consider in connection with evaluating the proposals to be considered at the HSBI special meeting, see the documents incorporated by reference by First Bancshares into this joint proxy statement/prospectus referred to under “Where You Can Find More Information” beginning on page 175.

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 HSBI 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 HSBI 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, HSBI 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 HSBI shareholders.

After the closing of the merger, HSBI shareholders who receive shares of First Bancshares common stock in the merger will have different rights than they currently have as HSBI shareholders, which may be less favorable than their current rights as HSBI shareholders. For a detailed discussion of the significant differences between the current rights of a shareholder of HSBI and the rights of a shareholder of the combined company following the merger, see “Comparison of Rights of First Bancshares shareholders and HSBI Shareholders” beginning on page 159.

Risks Related to First Bancshares’ Business

There are certain risks relating to First Bancshares’ business.

You should read and consider risk factors specific to First Bancshares’ business that will also affect the combined company after the merger. These risks are described in the section entitled “Risk Factors” in First Bancshares’ Annual Report on Form 10-K for the year ended December 31, 2021 and in other documents incorporated by reference into this joint proxy statement/prospectus. See “Where You Can Find More Information” on page 175 for the location of information incorporated by reference into this joint proxy statement/prospectus.

Recommendation of the First Bancshares Board of Directors

On July 21, 2022, the First Bancshares board of directors unanimously approved the merger agreement and the transactions contemplated thereby. Based on First Bancshares’ reasons for the merger described in the section of this joint proxy statement/prospectus entitled “The Merger — First Bancshares’ Reasons for the Merger; Recommendation of the First Bancshares Board of Directors” beginning on page 56, the First Bancshares board of directors believes that the merger and the issuance of shares of First Bancshares

TABLE OF CONTENTS

common stock as merger consideration is in the best interests of First Bancshares shareholders. Accordingly, the First Bancshares board of directors unanimously recommends that its shareholders vote “FOR” the First Bancshares merger proposal and, if necessary, vote “FOR” the First Bancshares adjournment proposal.

Record Date and Quorum

The First Bancshares board of directors has fixed the close of business on [ ], 2022 as the First Bancshares record date, which is the date for determining the holders of First Bancshares common stock entitled to receive notice of and to vote at the First Bancshares special meeting. As of the First Bancshares record date, there were [ ] shares of First Bancshares common stock outstanding and entitled to notice of, and to vote at, the First Bancshares special meeting or any adjournment thereof, and such outstanding shares of First Bancshares common stock were held by [ ] holders of record. Each share of First Bancshares common stock entitles the holder to one vote at the First Bancshares special meeting on each proposal to be considered at the First Bancshares special meeting.

The holders of a majority of the shares of First Bancshares common stock issued and outstanding and entitled to vote at the First Bancshares special meeting must be present, either in person or by proxy, to constitute a quorum at the First Bancshares special meeting. Abstentions and shares held of record by a broker or nominee that are voted on any matter are included in determining whether a quorum exists. Broker non-votes, if any, will not be included in determining whether a quorum exists. No business may be transacted by the holders of First Bancshares common stock at the First Bancshares special meeting unless a quorum is present.

Required Vote; Treatment of Abstentions; Broker Non-Votes and Failure to Vote

The First Bancshares Merger Proposal. The affirmative vote of the holders of at least a majority of the outstanding shares of First Bancshares common stock is required to approve the First Bancshares merger proposal. If you fail to vote in person or by proxy or fail to instruct your bank, broker or other nominee to vote, of if you mark “ABSTAIN” on your proxy card, with respect to the First Bancshares merger proposal, it will have the same effect as a vote “AGAINST” the proposal.

The First Bancshares Adjournment Proposal. The number of votes cast in favor of “FOR” the First Bancshares adjournment proposal exceeding the number of votes cast “AGAINST” the First Bancshares adjournment proposal is required to approve the proposal. If you fail to vote in person or by proxy or fail to instruct your bank, broker or other nominee to vote, or if you mark “ABSTAIN” on your proxy card, with respect to the First Bancshares adjournment proposal, you will not be deemed to have cast a vote with respect to such proposal, and it will have no effect on such proposal.

The First Bancshares board of directors encourages you to complete, date and sign the enclosed proxy card that is applicable to your shares of First Bancshares common stock and return it promptly in the enclosed postage-paid envelope so that your voice is heard on these matters.

Voting and Revocation of Proxies

Proxies, in the forms enclosed, which are properly executed and returned and not subsequently revoked, will be voted in accordance with the instructions indicated on the proxies. Any properly executed proxy on which voting instructions are not specified will be voted “FOR” the First Bancshares merger proposal and “FOR” the First Bancshares adjournment proposal, if applicable.

If you are a shareholder of record of First Bancshares as of [ ], 2022, the First Bancshares record date, you may submit your proxy before the First Bancshares special meeting in any of the following ways:

•

You may vote online. You may vote online by accessing [ ]. Have your proxy card available.

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

If you intend to submit your proxy by telephone or via the internet, you must do so by 11:59 P.M. Eastern Time on the day before the First Bancshares special meeting. If you intend to submit your proxy by mail, your completed proxy card must be received prior to the First Bancshares special meeting.

•

delivering written notice of revocation to the Corporate Secretary of First Bancshares;

•

timely submitting another proxy online or by telephone or mail prior to the First Bancshares special meeting; or

•

attending the First Bancshares special meeting and notifying the election officials that you wish to revoke your proxy and vote at the meeting.

All written notices of revocation and other communications with respect to revocation or proxies should be sent to: Post Office Box 15549, Hattiesburg, Mississippi, 39404 Attn: Corporate Secretary, Attention: Corporate Secretary. Attendance at the First Bancshares special meeting will not, by itself, revoke your proxy. If you hold your shares in street name with a bank or broker, you must contact such bank or broker for instructions as to how to revoke your proxy.

Shares Held in “Street Name”; Broker Non-Votes

Banks, brokers and other nominees who hold shares of First Bancshares 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. Broker non-votes are shares held by a broker, bank or other nominee that are represented at the First Bancshares special meeting, but with respect to which the broker or nominee is not instructed by the beneficial owner of such shares to vote on the particular proposal and the broker does not have discretionary voting power on such proposal. As a result, we do not expect any broker non-votes at the First Bancshares special meeting.

If your broker, bank or other nominee holds your shares of First Bancshares common stock in “street name,” your broker, bank or other nominee will vote your shares of First Bancshares common stock 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 joint proxy statement/prospectus.

Shares Subject to Voting Agreement; Shares Held by Directors and Executive Officers

All directors and executive officers of First Bancshares, solely in their capacity as shareholders of First Bancshares, have entered into voting agreements with HSBI pursuant to which they have agreed to vote their shares of First Bancshares common stock in favor of the approval of the merger agreement and the transactions contemplated thereby, including the issuance of shares of First Bancshares common stock as merger consideration in the merger. As of the First Bancshares record date, [ ] shares of First Bancshares common stock, or approximately [ ]% of the outstanding shares of First Bancshares common stock entitled to vote at the First Bancshares special meeting, are bound by the voting agreements.

Solicitation of Proxies; Expenses

This proxy solicitation is made by the First Bancshares board of directors. First Bancshares is responsible for its expenses incurred in preparing, assembling, printing, and mailing this joint proxy statement/prospectus. Proxies will be solicited through the mail. Additionally, directors and officers of First Bancshares intend to solicit proxies personally or by telephone or other means of communication. The directors and officers will not be additionally compensated for any such solicitation. First Bancshares will reimburse banks, brokers, and other custodians, nominees and fiduciaries for their reasonable expenses in forwarding the

TABLE OF CONTENTS

proxy materials to beneficial owners. In addition, First Bancshares retains the discretion to engage a third-party proxy solicitor to assist First Bancshares in soliciting proxies from the First Bancshares shareholders.

Attending the First Bancshares Special Meeting

All shareholders of First Bancshares as of the First Bancshares record date, including shareholders of record and shareholders who hold their shares in “street name” through banks, brokers, nominees or any other holder of record as of the First Bancshares record date, are invited to attend the First Bancshares special meeting. Shareholders of record of First Bancshares common stock can vote in person at the First Bancshares special meeting. If you are not a shareholder of record as of the First Bancshares record date, you must obtain a proxy card, 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 First Bancshares special meeting. The use of cameras, sound recording equipment, communications devices or any similar equipment during the First Bancshares special meeting is prohibited without First Bancshares’ express written consent.

A First Bancshares shareholder who holds shares in “street name” through a broker, bank, trustee or other nominee (which we refer to as a “beneficial owner”) who desires to attend the First Bancshares special meeting must provide proof of beneficial ownership as of the First Bancshares 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.

First Bancshares Merger Proposal

First Bancshares is asking its shareholders to approve the First Bancshares merger proposal. Holders of First Bancshares common stock should read this joint proxy statement/prospectus carefully and in its entirety, including the annexes, for more detailed information concerning the merger agreement and the merger. A copy of the merger agreement is attached to this joint proxy statement/prospectus as Annex A.

After careful consideration, the First Bancshares board of directors, by a unanimous vote of all directors, approved the merger agreement and declared the merger agreement and the transactions contemplated thereby, including the merger and the issuance of shares of First Bancshares common stock as merger consideration, to be advisable and in the best interest of First Bancshares and its shareholders. See “The Merger — First Bancshares’ Reasons for the Merger; Recommendation of the First Bancshares Board of Directors” beginning on page 56 of this joint proxy statement/prospectus for a more detailed discussion of the First Bancshares board of directors’ recommendation.

The First Bancshares board of directors unanimously recommends a vote “FOR” the First Bancshares merger proposal.

First Bancshares Adjournment Proposal

The First Bancshares special meeting may be adjourned to another time or place, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the First Bancshares special meeting to approve the First Bancshares merger proposal.

If, at the First Bancshares special meeting, the number of shares of First Bancshares common stock present or represented and voting in favor of the First Bancshares merger proposal is insufficient to approve the First Bancshares merger proposal, First Bancshares intends to move to adjourn the First Bancshares special meeting in order to enable the First Bancshares board of directors to solicit additional proxies for approval of the First Bancshares merger proposal. In that event, First Bancshares will ask the holders of First Bancshares common stock to vote upon the adjournment proposal, but not the First Bancshares merger proposal.

In this proposal, First Bancshares is asking the holders of First Bancshares common stock to authorize the holder of any proxy solicited by the First Bancshares board of directors on a discretionary basis to vote in favor of adjourning the First Bancshares special meeting to another time and place for the purpose of soliciting additional proxies, including the solicitation of proxies from First Bancshares shareholders who have previously voted.

•

a proposal to approve the merger agreement, which we refer to as the HSBI merger proposal;

•

a proposal to approve certain compensatory payments that Brad Serff is or may be entitled to receive in connection with the merger and bank merger, or certain subsequent events, which we refer to as the 280G proposal,

any other matters as may properly be brought before the HSBI special meeting or any adjournment or postponement of the HSBI special meeting.

If any other matters are properly presented, however, and you have completed, signed and submitted your proxy, the person(s) named as proxy will have the authority to vote your shares in accordance with his or her judgment with respect to such matters. A copy of the merger agreement is included in this joint proxy statement/prospectus as Appendix A, and we encourage you to read it carefully in its entirety.

Recommendation of the HSBI Board of Directors

The HSBI board of directors recommends that HSBI shareholders vote “FOR” the HSBI merger proposal, “FOR” the 280G proposal and “FOR” the HSBI adjournment proposal. See “The Merger — HSBI’s Reasons for the Merger and Recommendations of the HSBI Board of Directors.”

TABLE OF CONTENTS

Record Date and Quorum

[ ], 2022 has been fixed as the record date for the determination of HSBI shareholders entitled to notice of, and to vote at, the HSBI special meeting and any adjournment or postponement thereof. At the close of business on the record date, there were [ ] shares of HSBI common stock outstanding and entitled to vote at the HSBI special meeting, held by approximately [ ] holders of record.

A quorum is necessary to transact business at the HSBI special meeting. The presence, in person or by proxy, of the holders of a majority of the outstanding shares of HSBI common stock entitled to vote at the meeting is necessary to constitute a quorum. Shares of HSBI stock represented at the HSBI special meeting but not voted, including shares that a shareholder abstains from voting, will be counted for purposes of establishing a quorum. Once a share of HSBI stock is represented at the HSBI special meeting, it will be counted for the purpose of determining a quorum not only at the HSBI special meeting but also at any adjournment or postponement of the HSBI special meeting. In the event that a quorum is not present at the HSBI special meeting, it is expected that the HSBI special meeting will be adjourned or postponed.

Required Vote

The affirmative vote of a majority of the outstanding shares of HSBI common stock must vote in favor of the HSBI merger proposal to approve the merger agreement. If you vote to “ABSTAIN” with respect to the HSBI merger proposal or if you fail to vote on the HSBI merger proposal, this will have the same effect as voting “AGAINST” the HSBI merger proposal.

Mr. Serff and his related shareholders (collectively, “ineligible shareholders”) may not vote on the 280G proposal. Any votes received from an ineligible shareholder on the 280G proposal will be disregarded. For purposes of Section 280G, the term “ineligible shareholder” includes each individual whose payments are subject to the vote, his or her parents, children and grandchildren, and certain entities in which he or she has a direct or indirect ownership interest. If you are an “ineligible shareholder,” a separate notice concerning your status has been mailed to you at the same time as the delivery to you of your copy of the proxy statement/prospectus. As an ineligible shareholder, any vote (whether in favor or in opposition) that you cast on the 280G proposal will be disregarded. Approval of the 280G proposal is not a condition of the merger, and these proposals are separate from the vote on the HSBI merger proposal.

Each share of HSBI common stock you own as of the record date for the HSBI special meeting entitles you to one vote at the HSBI special meeting on all matters properly presented at the meeting.

How to Vote — Shareholders of Record

Voting in Person. If you are a shareholder of record, you can vote in person by submitting a ballot at the HSBI special meeting. Nevertheless, we recommend that you vote by proxy as promptly as possible, even if you plan to attend the HSBI special meeting. This will ensure that your vote is received. If you attend the HSBI special meeting, you may vote by ballot, thereby canceling any proxy previously submitted.

Voting by Proxy. Your proxy card includes instructions on how to vote by mailing in the proxy card.

If you sign and return your proxy (whether by mail, Internet,

TABLE OF CONTENTS

fax or telephone) without instruction on how to vote your shares, your shares will be voted “FOR” the HSBI merger proposal, “FOR” the 280G proposal and “FOR” the HSBI adjournment proposal. At this time, the HSBI board of directors is unaware of any other matters that may be presented for action at the HSBI special meeting. If any other matters are properly presented, however, and you have signed and returned your proxy card, the person(s) named as proxy will have the authority to vote your shares in accordance with his or her judgment with respect to such matters.

If you choose to send a completed proxy card bearing a later date or a notice of revocation, the new proxy card or notice of revocation must be received before the beginning of the HSBI special meeting. Attendance at the HSBI special meeting will not, in and of itself, constitute revocation of a proxy.

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 joint proxy statement/prospectus. We urge you to carefully read 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 HSBI’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 HSBI by First Bancshares pursuant to the merger of HSBI with and into First Bancshares, with First Bancshares as the surviving company, which we refer to as the merger. Immediately after the merger, Heritage Southeast Bank, a wholly owned bank subsidiary of HSBI, 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 HSBI stock issued and outstanding immediately prior to the effective time of the merger will be converted into the right to receive 0.965, or the exchange ratio, of a share of First Bancshares common stock.

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 HSBI 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.

HSBI 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 $23.74, and (ii) the decline in the price of First Bancshares common stock (as measured by the average closing price divided by $29.68) 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 $116.02); provided, however, that First Bancshares has the option, but not the obligation, to adjust the exchange ratio to prevent the termination of merger agreement.

First Bancshares shareholders and HSBI 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

HSBI’s board of directors and senior management have from time to time engaged in reviews and discussions of long-term strategies and objectives and have considered ways to enhance the company’s performance and long-term shareholder value. These reviews have included periodic discussions with respect to potential business combination transactions that would further the company’s long-term strategic objectives and the potential benefits and risks of any such transaction. As part of these strategic reviews and discussions, HSBI has considered a number of factors, including, among others, that additional scale could enhance operating efficiencies, growth and profitability, the technological and regulatory challenges faced by smaller community banks, and the competitive landscape for financial institutions.

HSBI has periodically had discussions with various financial institutions and investment bankers regarding potential business combination transactions. These discussions have occurred during contacts

TABLE OF CONTENTS

through both scheduled and impromptu meetings at banking industry conferences, social settings at such conferences and other meetings and telephone calls.

In October of 2020, HSBI’s significant shareholder, Mr. Ken Lehman, was approached by representatives of VyStar Credit Union (“VyStar”) indicating potential interest of VyStar with respect to a transaction with HSBI and Heritage Southeast Bank. Over the remainder of 2020 and in January 2021, VyStar and HSBI continued discussions regarding a potential transaction, including preliminary due diligence reviews and pricing expectations.

On January 28, 2021, an investment banking firm known to both Messrs. Leonard Moreland, Chief Executive Officer of HSBI, and Ray “Hoppy” Cole, President and Chief Executive Officer of First Bancshares arranged for a meeting at the offices of the investment banking firm. Mr. Moreland and Mr. Cole discussed each bank’s organizational culture and history, business lines and strategy, and respective views on the industry outlook and future plans. Mr. Moreland noted from the meeting that there were significant similarities, with considerable geographic and strategic alignment between HSBI and First Bancshares. Mr. Moreland and Mr. Cole agreed to follow up the meeting in April 2021 after each bank had completed their first quarter.

In connection with the discussions with VyStar, HSBI’s board created a special committee of outside directors, consisting of Jeff Arnold, Roy Hall, John Mansour, David Rupp and John Presley (the “Special Committee”). In late January 2021, VyStar submitted a draft letter of intent proposing a purchase price that would result in a net price available to HSBI shareholders of approximately $27.00 per outstanding HSBI share. The letter of intent included a number of additional deal terms, including terms dealing with transaction structure, management change-in-control agreements, employees, benefit plans, contingencies, indemnification and deal protection, including a requirement that HSBI negotiate exclusively with VyStar.

Following a few modifications to the letter of intent, HSBI and VyStar executed a non-binding letter of intent on February 3, 2021, commenced additional due diligence on each other, and negotiated a definitive agreement. On March 31, 2021, following unanimous approval by HSBI’s Special Committee and board of directors, HSBI executed a definitive agreement with VyStar for the proposed purchase of substantially all of the assets of Heritage Southeast Bank. The definitive agreement between HSBI and VyStar provided for a net purchase price to HSBI’s shareholders of $27.00 per share, with a potential increase to reflect HSBI’s per share net income after October 1, 2021 in the event the transaction was not closed prior to October 31, 2021. The definitive agreement including a number of customary closing conditions, including HSBI shareholder approval and receipt of necessary regulatory approvals by HSBI and VyStar. The definitive agreement restricted HSBI’s ability to solicit any competing offer. The definitive agreement provided that either party could terminate the definitive agreement in the event that the transaction did not close by December 31, 2021, but in the event that the regulatory approvals were the only condition not satisfied, VyStar had the right to extend the definitive agreement through March 31, 2022.

In light of the announced proposed transaction between HSBI and VyStar, HSBI and First Bancshares did not schedule a follow-up meeting as previously agreed upon. Following the announcement of the proposed VyStar transaction, Mr. Cole reached out to Mr. Moreland to congratulate him on the announcement, and both parties wished the other the best.

HSBI and VyStar subsequently diligently sought satisfaction of the closing conditions for the proposed transaction, submitting all necessary regulatory applications and seeking HSBI shareholder approval. On July 12, 2021, HSBI’s shareholders approved the proposed transaction between HSBI and VyStar.

Throughout the remainder of 2021 and into 2022, HSBI and VyStar continued to pursue the necessary regulatory approvals from the FDIC, the NCUA, the Georgia Department of Banking and Finance and the Florida Office of Financial Regulation. On October 29, 2021, the parties mutually agreed to waive their respective rights to terminate the definitive agreement on or after December 31, 2021 until February 28, 2022. On February 28, 2022, the parties again agreed to extend the time available to obtain regulatory approvals and satisfy other closing conditions. This waiver aligned with the terms originally negotiated in the definitive agreement, which provided for an outside date of March 31, 2022, if receipt of regulatory approvals remains the only material outstanding condition to closing.

TABLE OF CONTENTS

As the potential transaction with VyStar continued to be extended, from time to time, various third parties approached management of HSBI in a perceived effort to determine if the VyStar transaction was going to receive regulatory approval, and to indicate potential interest in a negotiated transaction with HSBI in the event that the VyStar transaction did not close. First Bancshares was among the institutions, commencing in 2022, that reached out to Mr. Moreland seeking to discuss a potential future transaction. In light of the exclusivity requirements contained in the agreement with VyStar, in each instance, Mr. Moreland indicated that HSBI was continuing to work diligently with VyStar to obtain the necessary regulatory approvals.

While the parties continued to seek the necessary regulatory approvals, no assurances could be obtained that the regulatory approvals would be forthcoming, or forthcoming in a timely manner. As the board of HSBI felt that the definitive agreement continued to provide an attractive result for HSBI’s shareholders if regulatory approvals could be obtained, the Special Committee and board of HSBI was reluctant to terminate the agreement without some comfort that an alternative transaction may be available.

In March 2022, as the outside date of the definitive agreement approached, HSBI sought permission from VyStar to solicit third party interest while VyStar sought a further extension from HSBI to allow for the continued pursuit of regulatory approvals. On March 31, 2022, following approvals by the Special Committee and board, HSBI and VyStar agreed to: (i) extend the outside date for consummation of the transaction from March 31, 2022 to June 30, 2022, (ii) permit either party to terminate the definitive agreement in the event that all regulatory approvals were not in hand by April 30, 2022, and (iii) permit HSBI to solicit third party interest in an alternative transaction, provided that HSBI was prohibited from entering into an agreement with a third party so long as the agreement with VyStar remained in place.

On April 1, 2022, management of HSBI provided a request for proposals from five investment banks familiar with HSBI to facilitate HSBI’s identification of a strategic partner for a possible transaction. HSBI also prepared a data room with additional information regarding HSBI to facilitate the investment bankers’ ability to assess HSBI’s condition and prospects. Management of HSBI also reached out to a few banks, including First Bancshares, to invite them to join the data room.

On April 6, 2022, HSBI and First Bancshares executed a non-disclosure agreement and First Bancshares was granted access to HSBI’s initial data room.

On April 11, 2022, the board of directors, including the Special Committee, met with representatives of each of the invited investment banks. The presentations typically include formal and informal presentations from each firm regarding the overall banking industry and markets, nationally and in Georgia; representative engagements of the firm; and the proposed scope of services to HSBI. Following the presentations and further discussions with representatives of Nelson Mullins Riley & Scarborough LLP (“Nelson Mullins”), HSBI’s legal counsel, the board selected Piper Sandler to serve as its exclusive financial advisor.

During the period of April 11 through May 5, 2022, members of HSBI’s management team advanced the prospective sale process preparations, including preparation of a confidential information memorandum and key, customary due diligence materials on HSBI as commonly requested by prospective buyers.

Beginning on May 5, 2022, Piper Sandler began its outreach to prospective buyers, which included 35 potentially interested parties, including First Bancshares, seeking non-binding indications of interest by June 6, 2022. The communication was intended to verify the list of interested parties, obtain signed non-disclosure agreements from interested parties, provide initial information, and advance discussions. During this time, Piper Sandler and management provided updates to the Strategic Committee and HSBI board as to process status and initial feedback regarding interest in advancing strategic dialogue. Eight parties, including First Bancshares, ultimately signed non-disclosure agreements, and three parties, again including First Bancshares, submitted non-binding indications of interest.

On May 18, 2022, Mr. Lehman met with Mr. Cole at First Bancshares’ offices in Hattiesburg, Mississippi to discuss a potential business combination between HSBI and First Bancshares, at which meeting Mr. Cole presented Mr. Lehman with an initial preliminary term sheet for the acquisition of HSBI by First Bancshares, which contemplated a proposed implied deal value of $29.00 per share or approximately $210 million in the aggregate.

TABLE OF CONTENTS

On June 3, 2022, at a meeting of the executive committee of the board of directors of First Bancshares, First Bancshares’ management team discussed the opportunity to bid on a potential business combination transaction with HSBI, and previewed the proposed indication of interest for the executive committee.

On June 6, 2022, three banks approached by Piper Sandler submitted non-binding indications of interest to acquire HSBI. First Bancshares’ indication of interest provided for a fixed exchange ratio of 0.9500 shares, which implied a deal value of $28.59 per share or $206.9 million in the aggregate. Another Southeastern based Bank (“Bank A”) that was larger than First Bancshares in total assets, submitted a non-binding indication of interest with a proposed fixed exchange ratio in a range which implied a deal value of between $24.59 and $27.02 per share, or $177.9 million to $195.6 million in the aggregate. Another Southeast based bank (“Bank B”) that was smaller than First Bancshares in total assets, submitted a non-binding indication of interest with a proposed fixed exchange ratio which implied a deal value of $27.95 per share or $202.0 million in the aggregate. Each of non-binding indication of interests included other comparable customary provisions, and each required termination of the definitive agreement with VyStar prior to execution of the indication of interest.

On June 8, 2022, HSBI’s board of directors met with representatives of Piper Sandler and Nelson Mullins to discuss the received indications of interest. Representatives of Piper Sandler reviewed the process that resulted in the three indications of interest, including some of the reasons offered by those that declined to submit indications of interest, noting that in Piper Sandler’s opinion, none of the potential buyers who did not submit indications of interest were likely to become a legitimate alternative in the near future. Representatives of Piper Sandler then provided a bid overview analysis to the board and management of HSBI, including a review of each of the potential parties that submitted indications of interests, key terms of each of the indications of interest, including pricing metrics and terms, management related terms, overall transaction value to the HSBI, various metrics, including pricing multiples, earn-back periods, earnings accretion/dilution and proforma dividend analysis, historical pricing range analysis based upon the exchange ratios contained in the indications of interest, preliminary pro-forma financial impacts, contribution analysis, peer analysis, merger and acquisition precedent transactions analysis and comparisons (national and regional), and price performance and merger reaction analysis, as well as third party equity analyst recommendations the stock of each of the potential acquirers.

Representatives of Nelson Mullins and management provided an update to the board regarding the latest discussions with VyStar and the regulators, as well as potential timing for any regulatory approval of the proposed transaction with VyStar. Following discussion of the regulatory process and challenges, the HSBI board determined that it was unlikely that the VyStar transaction would receive the necessary regulatory approvals within a reasonable time period, and concluded that based on the competitive indications of interest from good and well-qualified strategic buyers, it was in HSBI’s interest to terminate the VyStar Transaction.

The board of HSBI discussed the pros and costs of each indication of interest before unanimously deciding that the indication of interest provided by First Bancshares was the preferred indication. Following discussions with representatives of Nelson Mullins and Piper Sandler, the board unanimously authorized management to (i) terminate the VyStar definitive agreement and (ii) negotiate and enter into an indication of interest with First Bancshares.

On June 9, 2022, representatives of Piper Sandler informed Banks A and B that HSBI was moving forward with a different party. At that time, Bank B submitted a revised proposal with terms felt by management to be slightly improved, but still likely inferior to the indication of interest received from First Bancshares. Representatives of Piper Sandler asked First Bancshares to submit its best and final indication of interest.

On June 10, 2022, First Bancshares submitted an updated indication of interest, increasing the fixed exchange ratio to 0.965 shares of First Bancshares for each outstanding share of HSBI.

On June 15, 2022, HSBI and VyStar mutually agreed to terminate their definitive agreement.

On June 16, 2022, HSBI and First Bancshares executed the non-binding indication of interest.

TABLE OF CONTENTS

During the period from June 16, 2022 through July 27, 2022, First Bancshares conducted due diligence across all aspects of HSBI. Due diligence information was provided to First Bancshares and its advisors across multiple venues, including, but not limited to, a virtual data room, conference calls, in person meetings, in person review of physical assets, and direct loan file reviews.

During this same period First Bancshares afforded HSBI certain reverse due diligence access. The due diligence was provided to HSBI and its advisors across customary venues including the virtual data room and conference calls. On July 22, 2022, a reverse due diligence conference call was held and included First Bancshares’ and HSBI’s senior management teams, legal counsels and financial advisors, with responses and resulting diligence deemed satisfactory by HSBI.

During the period from June 16, 2022, through July 27, 2022, legal counsel for HSBI and legal counsel for First Bancshares, Alston & Bird LLP, or Alston & Bird, along with management of both companies, prepared, exchanged drafts and negotiated the terms of the merger agreement and the related ancillary documents and agreements (including disclosure schedules, the claims letter, form of voting agreement, form of director non-compete and non-disclosure agreement, and form of lock-up agreement).

On July 21, 2022, the First Bancshares board of directors held a meeting that was also attended by the management team of First Bancshares and representatives of KBW, Alston & Bird, and D.A. Davidson. At the meeting, the management team of First Bancshares provided the board of directors with an update regarding the status of the negotiation of the definitive agreements with HSBI, along with an overview of the results of the due diligence that First Bancshares conducted in respect of HSBI. Representatives of Alston & Bird also reviewed with the First Bancshares board of directors the terms of the proposed merger agreement and support agreements and presented proposed resolutions for the boards of directors of First Bancshares and The First approving, among other things, the merger agreement and transactions contemplated by the merger agreement. KBW reviewed and discussed, among other matters, the financial aspects of the proposed merger, and advised the First Bancshares board of directors that, assuming no material changes in the proposed merger or KBW’s financial analysis, KBW would be in a position to deliver, in connection with the execution of the merger agreement, a written opinion (which was subsequently delivered on and dated July 27, 2022) to the First Bancshares board of directors, to the effect that, as of the date of such opinion and subject to the procedures followed, assumptions made, matters considered, and qualifications and limitations on the review undertaken by KBW as set forth in such opinion, the exchange ratio in the proposed merger was fair, from a financial point of view, to First Bancshares. See “— Opinions of First Bancshares’ Financial Advisors.” D.A. Davidson also reviewed and discussed with the First Bancshares board of directors the financial aspects of the proposed merger, and advised the First Bancshares board of directors that, assuming no material changes in the proposed merger or D.A. Davidson’s financial analysis, D.A. Davidson would be in a position to deliver, in connection with the execution of the merger agreement, a written opinion (which was subsequently delivered on and dated July 27, 2022) to the First Bancshares board of directors, to the effect that, as of the date of such opinion and subject to the procedures followed, assumptions made, matters considered, and qualifications and limitations on the review undertaken by D.A. Davidson as set forth in such opinion, the merger consideration to be paid by First Bancshares in the proposed merger was fair, from a financial point of view, to First Bancshares. See “— Opinions of First Bancshares’ Financial Advisors.”

At the July 21, 2022 meeting of the board of directors of First Bancshares, the First Bancshares board of directors, taking into consideration the matters discussed during the meeting and in prior meetings of the First Bancshares board of directors, including consideration of the factors described under “— Recommendation of the First Bancshares Board of Directors and Reasons for the Merger,” determined that the merger agreement and the transactions contemplated by the merger agreement, including the merger and issuance of shares of First Bancshares common stock in connection with the merger, were advisable and in the best interests of First Bancshares and its shareholders and approved the execution, delivery and performance of the merger agreement, and recommended that the First Bancshares shareholders approve the First Bancshares merger proposal.

On July 26, 2022, a meeting of the Special Committee and board was held by HSBI, including management, representatives of Piper Sandler, and representatives of Nelson Mullins. The Special Committee and HSBI board reviewed a draft of the Merger Agreement, with summary and key matters presented by representatives of Nelson Mullins. HSBI’s management provided a summary of the reverse due diligence

performed on First Bancshares. Representative of Piper Sandler provided an update as to the valuation metrics, current market conditions and First Bancshares stock price.

During this meeting, legal counsel’s review of the merger agreement included major provisions regarding purchase price, representations and warranties and disclosure schedules, interim operating covenants, registration statement and proxy statement process, fiduciary out, employee benefits, indemnification, conditions to closing and termination provisions and fees, as well as the related Director agreements. Representatives of Nelson Mullins provided a review of director fiduciary duties, the final Merger Agreement and director agreements, as well as the form of resolutions to be considered for approval by the Special Committee, HSBI board and Heritage Southeast Bank board.

HSBI management’s review of reverse due diligence was presented and concluded there were no extraordinary concerns or unknown matters uncovered during the diligence of First Bancshares. The review included corporate strategy, earnings, asset quality, deposit franchise, sensitivity and interest rate risk, legal and regulatory matters, and capital adequacy.

Representative of Piper Sandler provided additional market context and analysis regarding the current valuation and stock price metrics. Representatives of Piper Sandler presented its review of its fairness opinion analysis and fairness opinion.

The Special Committee, HSBI board and Heritage Southeast Bank board voted unanimously to approve the resolutions approving the merger agreement (including the annexes, schedules and exhibits thereto). The forms voting agreements, claims letter agreement, director non-compete and non-disclosure agreement, and lock-up agreement were unanimously approved.

On July 27, 2022, HSBI delivered the fully signed merger agreement documents and related agreements (including the annexes, schedules and exhibits thereto), as well as the signed voting agreements, claims letter agreements, director non-compete and non-disclosure agreements, and lock-up agreement, to First Bancshares counsel, and copies of First Bancshares’s signature pages to the various agreements were delivered to HSBI’s counsel. After the close of markets, the transaction was publicly announced by First Bancshares, and related communications were initiated.

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:

•

each of First Bancshares’ and HSBI’s business, operations, financial condition, asset quality, earnings and prospects;

•

the strategic fit of the businesses of the two companies, including their complementary markets, business lines and loan and deposit profiles;

•

the opportunity to strategically expand into new markets in Georgia and Florida;

•

the anticipated pro forma impact of the transaction on the combined company, including the expected impact on financial metrics including earnings and tangible book value and regulatory capital levels, as well as the potential efficiencies of scale resulting from the increased size of First Bancshares following the merger;

•

its understanding of the current and prospective environment in which First Bancshares and HSBI operate, including national, state and local economic conditions, the competitive environment for financial institutions generally, and the likely effect of these factors on First Bancshares both with and without the proposed transaction;

•

its review and discussions with First Bancshares’ management concerning the due diligence investigation of HSBI, including its review of HSBI’s financial condition, results of operation, asset quality, market areas, growth potential (projected potential accretion to earnings per share and the projected payback period of the estimated decrease in tangible book value) and quality of senior management;

•

the perceived compatibility of the corporate cultures of the two companies, which management believes should facilitate integration and implementation of the transaction;

•

the regulatory and other approvals required in connection with the merger and the expectation that such regulatory approvals will be received in a timely manner and without the imposition of unacceptable conditions; and

the financial and other terms of the merger agreement, including the merger consideration, expected tax treatment, the deal protection and termination fee provisions, and restrictions on the conduct of HSBI’s business between the date of the merger agreement and the date of completion of the merger.

First Bancshares’ board of directors also considered potential risks relating to the merger including the following:

•

First Bancshares management’s attention and First Bancshares resources may be diverted from the operation of First Bancshares’ business and towards the completion of the merger;

•

First Bancshares may not realize all of the anticipated benefits of the merger, including cost savings, maintenance of existing customer and employee relationships, and minimal disruption in the integration of HSBI’s operations with First Bancshares;

The foregoing discussion of the information and factors considered by the First Bancshares board of directors is forward-looking in nature. This information should be read in light of the factors described under the section entitled “Cautionary Statement Concerning Forward-Looking Statements.”

HSBI’s Reasons for the Merger

After careful consideration, HSBI’s board of directors, at a meeting held on July 26, 2022, determined that the merger agreement is advisable, fair to and in the best interests of HSBI and its shareholders.

TABLE OF CONTENTS

Accordingly, HSBI’s board of directors adopted and approved the merger agreement and the merger and the other transactions contemplated by the merger agreement and recommends that HSBI shareholders vote “FOR” the approval of the merger agreement. In reaching its decision to adopt and approve the merger agreement and the merger and the other transactions contemplated by the merger agreement, and to recommend that its shareholders approve the merger agreement, the HSBI board of directors evaluated the merger and the merger agreement in consultation with HSBI’s management, as well as its financial and legal advisors, and considered a number of factors, including the following material factors:

•

each of HSBI’s, First Bancshares’s and the combined company’s business, operations, financial condition, asset quality, earnings and prospects. In reviewing these factors, the HSBI board of directors considered its view that First Bancshares’s business and operations complement those of HSBI and that the merger would result in a combined company with diversified revenue sources, a well-balanced loan portfolio and an attractive funding base;

•

the perceived value of the consideration to be received by HSBI’s shareholders, including in relation to the then-current value of HSBI in relation to recent trading activity;

•

the complementary nature of the cultures of the two companies, which management believes should facilitate integration and implementation of the transaction;

•

the fact that the merger consideration will consist of shares of First Bancshares common stock, resulting in pro forma ownership by HSBI shareholders in First Bancshares following the closing of the merger in an approximate range of 23% of the outstanding First Bancshares shares, which would allow HSBI shareholders to participate in a significant portion of the future performance of the combined HSBI and First Bancshares business and synergies resulting from the merger, and the value to HSBI shareholders represented by that consideration;

•

its understanding of the current and prospective environment in which HSBI and First Bancshares operate, including national and local economic conditions, the interest rate environment, increasing operating costs resulting from regulatory initiatives and compliance mandates, the competitive environment for financial institutions generally, and the likely effect of these factors on HSBI both with and without the proposed transaction;

•

the expectation that the combined company will have a strong capital position upon completion of the transaction, and the expectation that the necessary regulatory approvals will be received in a timely manner and without the imposition of unacceptable conditions;

•

the recommendation of the Special Committee, consisting of all of the outside directors of HSBI, that the transaction with First Bancshares was in the best interest of HSBI and its shareholders;

•

the financial analyses of Piper Sandler, HSBI’s financial advisor, and the opinion delivered by Piper Sandler to HSBI’s board of directors on July 26, 2022, to the effect that, as of the date of such opinion, and subject to the procedures followed, assumptions made, matters considered, and qualifications and limitations on the review undertaken by Piper Sandler as set forth in its opinion, the merger consideration was fair to the holders of HSBI common stock from a financial point of view, as more fully described in the section entitled “The Merger — Opinion of HSBI’s Financial Advisor”;

•

potential alternative exit strategies for HSBI in light of the shrinking number of potential buyers for community banks;

•

the fact that the merger consideration paid in the form of First Bancshares common stock is expected to be tax-free to HSBI shareholders;

•

the greater liquidity in the trading market for First Bancshares common stock relative to the market for HSBI stock due to the listing of First Bancshares’s shares on the Nasdaq Global Select Market, and the comparative prospects for gaining shareholder liquidity;

•

the opportunity for HSBI shareholders to receive First Bancshares common stock which has historically paid a cash dividend as compared to the HSBI shares for which no cash dividend has been paid;

•

its view that the size of the institution and related economies of scale were becoming increasingly important to continued success in the current financial services environment, including the increased

TABLE OF CONTENTS

expenses of regulatory compliance, and that a merger with a larger bank holding company could provide those economies of scale, increase efficiencies of operations and enhance customer products and services;

•

its review and discussions with HSBI’s management regarding strategic alternatives available to HSBI for enhancing value over the long term, including continuing to operate independently, and the potential risks, rewards and uncertainties associated with such alternatives and the benefits of an acquisition by First Bancshares compared to such other alternatives;

•

the exchange ratio is fixed so that if the market price of First Bancshares common stock is higher at the time of the closing of the merger, the economic value of the merger consideration to be received by HSBI shareholders in exchange for their shares of HSBI stock will also be higher;

•

the financial and other terms of the merger agreement, the expected tax treatment and deal protection provisions, including the ability of HSBI’s board of directors, under certain circumstances, to withdraw or materially adversely modify its recommendation to HSBI shareholders that they approve the merger agreement (subject to payment of a termination fee), each of which it reviewed with its outside financial and legal advisors;

•

that HSBI’s directors and executive officers have financial interests in the merger in addition to their interests as HSBI shareholders, including financial interests that are the result of compensation arrangements with HSBI, and the manner in which such interests would be affected by the merger; and

•

the short-term and long-term social and economic effects on the employees, customers, shareholders and other constituents of HSBI and Heritage Southeast Bank, and on the communities within which Heritage Southeast Bank operates.

The HSBI board of directors also considered a number of potential risks and uncertainties associated with the merger in connection with its deliberation of the proposed transaction, including, without limitation, the following:

•

the risk that the merger may not be consummated or that the closing may be unduly delayed, including as a result of factors outside either party’s control;

•

the potential risk of diverting management attention and resources from the operation of HSBI’s business and towards the completion of the merger and the possibility of employee attrition or adverse effects on client and business relationships as a result of the announcement and pendency of the merger;

•

the requirement that HSBI conduct its business in the ordinary course and the other restrictions on the conduct of HSBI’s business prior to the completion of the merger, which may delay or prevent HSBI from undertaking business opportunities that may arise pending completion of the merger;

•

that under the merger agreement, subject to certain exceptions, HSBI cannot solicit competing acquisition proposals;

•

the potential risks associated with achieving anticipated cost synergies and savings and successfully integrating HSBI’s business, operations and workforce with those of First Bancshares and the risk of not realizing all of the anticipated benefits of the merger or not realizing them in the expected timeframe;

•

the possibility that HSBI will have to pay a $8 million termination fee to First Bancshares if the merger agreement is terminated under certain circumstances;

•

that the exchange ratio is fixed so that if the market price of First Bancshares common stock is lower at the time of the closing of the merger, the economic value of the merger consideration to be received by HSBI shareholders in exchange for their shares of common stock will also be lower; and

•

the other risks under the sections entitled “Cautionary Statement About Forward-Looking Statements” and “Risk Factors.”

In considering the recommendation of the HSBI board, you should be aware that certain directors and officers of HSBI may have interests in the merger that are different from, or in addition to, interests of HSBI

TABLE OF CONTENTS

shareholders generally and may create potential conflicts of interest. HSBI’s board of directors was aware of these interests and considered them when evaluating and negotiating the merger agreement, the merger and the other transactions contemplated by the merger agreement, and in recommending to HSBI’s shareholders that they vote in favor of the proposal to approve the merger agreement. See “Interests of HSBI Executive Officers and Directors in the Merger.”

The foregoing discussion of the factors considered by the HSBI board of directors is not intended to be exhaustive, but, rather, includes the material factors considered by the HSBI board of directors. In reaching its decision to adopt and approve the merger agreement and the merger and the other transactions contemplated by the merger agreement, the HSBI board of directors did not quantify or assign any relative weights to the factors considered, and individual directors may have given different weights to different factors. The HSBI board of directors considered all these factors as a whole, including discussions with, and questioning of, HSBI’s management and HSBI’s financial and legal advisors, and overall considered the factors to be favorable to, and to support, its determination.

For the reasons set forth above, the HSBI board of directors has adopted and approved the merger agreement and the transactions contemplated thereby and recommends that you vote “FOR” the HSBI merger proposal, “FOR” the 280G proposal and “FOR” the HSBI adjournment proposal.

Each of the directors of HSBI and Heritgage Southeast Bank has entered into a voting agreement with First Bancshares, pursuant to which they have agreed to vote in favor of the HSBI merger proposal and the other proposals to be voted on at the HSBI special meeting, subject to the terms of the voting agreement. The voting agreements are discussed in more detail in the section entitled “Information About the HSBI Special Meeting — Shares Subject to Voting Agreements; Shares Held by Directors and Executive Officers.”

Opinion of HSBI’s Financial Advisor

HSBI retained Piper Sandler to act as financial advisor to HSBI’s board of directors in connection with HSBI’s consideration of a possible business combination. HSBI selected Piper Sandler to act as its financial advisor because Piper Sandler is a nationally recognized investment banking firm whose principal business specialty is financial institutions. In the ordinary course of its investment banking business, Piper Sandler is regularly engaged in the valuation of financial institutions and their securities in connection with mergers and acquisitions and other corporate transactions.

Piper Sandler acted as financial advisor to HSBI’s board of directors in connection with the proposed merger with The First Bancshares, Inc., which is referred to in this section as “FBMS”, and participated in certain of the negotiations leading to the execution of the agreement and plan of merger. At the July 26, 2022 meeting at which HSBI’s board of directors considered the merger and the agreement and plan of merger, Piper Sandler delivered to the board of directors its oral opinion, which was subsequently confirmed in writing on July 26, 2022, to the effect that, as of such date, the merger consideration is fair to the holders of HSBI’s common stock from a financial point of view. The full text of Piper Sandler’s opinion is attached as [•] to this proxy statement-prospectus. The opinion outlines the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by Piper Sandler in rendering its opinion. The description of the opinion set forth below is qualified in its entirety by reference to the full text of the opinion. Holders of HSBI common stock are urged to read the entire opinion carefully in connection with their consideration of the proposed merger.

Piper Sandler’s opinion was directed to the board of directors of HSBI in connection with its consideration of the merger and the agreement and plan of merger and does not constitute a recommendation to any shareholder of HSBI as to how any such shareholder should vote at any meeting of shareholders called to consider and vote upon the approval of the merger and the agreement and plan of merger. Piper Sandler’s opinion was directed only to the fairness, from a financial point of view, of the merger consideration to the holders of HSBI common stock and did not address the underlying business decision of HSBI to engage in the merger, the form or structure of the merger or any other transactions contemplated in the agreement and plan of merger, the relative merits of the merger as compared to any other alternative transactions or business strategies that might exist for HSBI or the effect of any other transaction in which HSBI might engage. Piper Sandler also did not express any opinion as to the fairness of the amount or nature of the compensation to be received in the merger by any officer, director or employee of HSBI or FBMS,

TABLE OF CONTENTS

or any class of such persons, if any, relative to the compensation to be received in the merger by any other shareholder. Piper Sandler’s opinion was approved by Piper Sandler’s fairness opinion committee.

In connection with its opinion, Piper Sandler reviewed and considered, among other things:

•

a draft of the agreement and plan of merger, dated July 25, 2022;

•

certain publicly available financial statements and other historical financial information of HSBI and its banking subsidiary, Heritage Southeast Bank, that Piper Sandler deemed relevant;

•

•

publicly available mean analyst net income and dividend per share estimates for FBMS for the years ending December 31, 2022 and December 31, 2023, as provided by the senior management of FBMS, as well as a long-term annual earnings per share growth rate and estimated dividends per share for FBMS for the years ending December 31, 2024 through December 31, 2026, as provided by the senior management of FBMS;

•

the pro forma financial impact of the merger on FBMS based on certain assumptions relating to transaction expenses, purchase accounting adjustments and cost savings, as well as an estimated net income growth rate for HSBI for the years ending December 31, 2025 and December 31, 2026, as provided by the senior management of FBMS;

•

the publicly reported historical price and trading activity for HSBI common stock and FBMS common stock, including a comparison of certain stock trading information for HSBI common stock and FBMS common stock and certain stock indices, as well as similar publicly available information for certain other companies, the securities of which are publicly traded;

•

a comparison of certain financial and market information for HSBI and FBMS with similar financial institutions for which information is publicly available;

•

the financial terms of certain recent business combinations in the bank and thrift industry (on a nationwide basis), to the extent publicly available;

•

the current market environment generally and the banking environment in particular; and

•

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

Piper Sandler also discussed with certain members of the senior management of HSBI and its representatives the business, financial condition, results of operations and prospects of HSBI and held similar discussions with certain members of the senior management of FBMS and its representatives regarding the business, financial condition, results of operations and prospects of FBMS.

In performing its review, Piper Sandler relied upon the accuracy and completeness of all of the financial and other information that was available to and reviewed by Piper Sandler from public sources, that was provided to Piper Sandler by HSBI or FBMS or their respective representatives, or that was otherwise reviewed by Piper Sandler, and Piper Sandler assumed such accuracy and completeness for purposes of rendering its opinion without any independent verification or investigation. Piper Sandler relied on the assurances of the respective managements of HSBI and FBMS that they were not aware of any facts or circumstances that would have made any of such information inaccurate or misleading in any respect material to its analyses. Piper Sandler was not asked to and did not undertake an independent verification of any of such information and Piper Sandler did not assume any responsibility or liability for the accuracy or completeness thereof. Piper Sandler did not make an independent evaluation or perform an appraisal of the specific assets, the collateral securing assets or the liabilities (contingent or otherwise) of HSBI or FBMS, nor was Piper Sandler furnished with any such evaluations or appraisals. Piper Sandler rendered no opinion or evaluation on the collectability of any assets or the future performance of any loans of HSBI or FBMS.

TABLE OF CONTENTS

Piper Sandler did not make an independent evaluation of the adequacy of the allowance for loan losses of HSBI or FBMS, or of the combined entity after the merger, and Piper Sandler did not review any individual credit files relating to HSBI or FBMS. Piper Sandler assumed, with HSBI’s consent, that the respective allowances for loan losses for both HSBI and FBMS were adequate to cover such losses and would be adequate on a pro forma basis for the combined entity.

In preparing its analyses, Piper Sandler used internal net income estimates for HSBI for the years ending December 31, 2022 through December 31, 2024 with an annual net income growth rate for the years ending December 31, 2025 and December 31, 2026, as provided by and confirmed with the senior management of HSBI. In addition, Piper Sandler used publicly available mean analyst net income and dividend per share estimates for FBMS for the years ending December 31, 2022 and December 31, 2023, as provided by the senior management of FBMS, as well as a long-term annual earnings per share growth rate and estimated dividends per share for FBMS for the years ending December 31, 2024 through December 31, 2026, as provided by the senior management of FBMS. Piper Sandler also received and used in its pro forma analyses certain assumptions relating to transaction expenses, purchase accounting adjustments and cost savings, as well as an estimated net income growth rate for HSBI for the years ending December 31, 2025 and December 31, 2026, as provided by the senior management of FBMS. With respect to the foregoing information, the respective senior managements of HSBI and FBMS confirmed to Piper Sandler that such information reflected (or, in the case of the publicly available analyst estimates referred to above, were consistent with) the best currently available estimates and judgments of those respective managements as to the future financial performance of HSBI and FBMS, respectively, and Piper Sandler assumed that the future financial performance reflected in such information would be achieved. Piper Sandler expressed no opinion as to such estimates or judgements, or the assumptions on which such information was based. Piper Sandler also assumed that there had been no material change in the respective assets, financial condition, results of operations, business or prospects of HSBI or FBMS since the date of the most recent financial statements made available to Piper Sandler. Piper Sandler assumed in all respects material to its analyses that HSBI and FBMS would remain as going concerns for all periods relevant to its analyses.

Piper Sandler also assumed, with HSBI’s consent, that (i) each of the parties to the agreement and plan of merger would comply in all material respects with all material terms and conditions of the agreement and plan of merger and all related agreements, that all of the representations and warranties contained in such agreements were true and correct in all material respects, that each of the parties to such agreements would perform in all material respects all of the covenants and other obligations required to be performed by such party under such agreements and that the conditions precedent in such agreements were not and would not be waived, (ii) in the course of obtaining the necessary regulatory or third party approvals, consents and releases with respect to the merger, no delay, limitation, restriction or condition would be imposed that would have an adverse effect on HSBI, FBMS, the merger or any related transactions, and (iii) the merger and any related transactions would be consummated in accordance with the terms of the agreement and plan of merger without any waiver, modification or amendment of any material term, condition or agreement thereof and in compliance with all applicable laws and other requirements. Finally, with HSBI’s consent, Piper Sandler relied upon the advice that HSBI received from its legal, accounting and tax advisors as to all legal, accounting and tax matters relating to the merger and the other transactions contemplated by the agreement and plan of merger. Piper Sandler expressed no opinion as to any such matters.

Piper Sandler’s opinion was necessarily based on financial, economic, regulatory, market and other conditions as in effect on, and the information made available to Piper Sandler as of, the date thereof. Events occurring after the date thereof could materially affect Piper Sandler’s opinion. Piper Sandler has not undertaken to update, revise, reaffirm or withdraw its opinion or otherwise comment upon events occurring after the date thereof. Piper Sandler expressed no opinion as to the trading value of HSBI common stock or FBMS common stock at any time or what the value of FBMS common stock would be once it is actually received by the holders of HSBI common stock.

In rendering its opinion, Piper Sandler performed a variety of financial analyses. The summary below is not a complete description of all the analyses underlying Piper Sandler’s opinion or the presentation made by Piper Sandler to HSBI’s board of directors, but is a summary of the material analyses performed and presented by Piper Sandler. 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

TABLE OF CONTENTS

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. Piper Sandler believes that its analyses 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 Piper Sandler’s comparative analyses described below is identical to HSBI or FBMS 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 transaction values, as the case may be, of HSBI and FBMS and the companies to which they were compared. In arriving at its opinion, Piper Sandler did not attribute any particular weight to any analysis or factor that it considered. Rather, Piper Sandler made qualitative judgments as to the significance and relevance of each analysis and factor. Piper Sandler 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, Piper Sandler made its determination as to the fairness of the merger consideration to the holders of HSBI common stock on the basis of its experience and professional judgment after considering the results of all its analyses taken as a whole.

In performing its analyses, Piper Sandler also made numerous assumptions with respect to industry performance, business and economic conditions and various other matters, many of which cannot be predicted and are beyond the control of HSBI, FBMS, and Piper Sandler. The analyses performed by Piper Sandler 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. Piper Sandler prepared its analyses solely for purposes of rendering its opinion and provided such analyses to HSBI’s board of directors at its July 26, 2022 meeting. Estimates on 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, Piper Sandler’s analyses do not necessarily reflect the value of HSBI common stock or FBMS common stock or the prices at which HSBI or FBMS common stock may be sold at any time. The analyses of Piper Sandler and its opinion were among a number of factors taken into consideration by HSBI’s board of directors in making its determination to approve the agreement and plan of merger and the analyses described below should not be viewed as determinative of the decision of HSBI’s board of directors with respect to the fairness of the merger consideration.

Summary of Proposed Merger Consideration and Implied Transaction Metrics.

Piper Sandler reviewed the financial terms of the proposed merger. Pursuant to the terms of the agreement and plan of merger, at the effective time of the merger each share of HSBI common stock issued and outstanding immediately prior to the effective time of the transaction, except for certain shares as set forth in the agreement and plan of merger, shall be converted into the right to receive 0.965 shares of FBMS common stock. Piper Sandler calculated an aggregate implied transaction value of approximately $203.6 million (based on 7,020,849 shares of HSBI common stock (including 6,000 unvested restricted stock awards), 194,110 HSBI Supplemental Executive Retirement Plan shares and 35,236 options with a weighted average strike price of $10.25 as of July 22, 2022), and an implied purchase price per share of $28.13 based on the closing price of FBMS common stock on July 22, 2022. Based upon financial information for HSBI as of or for the last twelve months (“LTM”) ended June 30, 2022 and the closing price of HSBI’s common stock on July 22, 2022, Piper Sandler calculated the following implied transaction metrics:

	Transaction Price Per Share / 6/30/2022 Tangible Book Value Per Share			177%
	Transaction Price Per Share / LTM Earnings per Share.			14.7x
	Transaction Price Per Share / 2022 Est. Earnings per Share(1)			12.5x
	Tangible Book Premium(2) / Core Deposits (CDs > $100k)			6.5%
	Market Premium as of July 22, 2022			30.5%

Net Present Value Analyses.

Piper Sandler performed an analysis that estimated the net present value of HSBI common stock assuming HSBI performed in accordance with internal net income estimates for HSBI for the years ending December 31, 2022 through December 31, 2024 with an annual net income growth rate for the years ending December 31, 2025 and December 31, 2026, as provided by and confirmed with the senior management of HSBI. To approximate the terminal value of a share of HSBI common stock at December 31, 2026, Piper Sandler applied price to LTM earnings multiples ranging from 9.00x to 12.75x and multiples of June 30, 2022 tangible book value ranging from 100% to 150%. The terminal values were then discounted to present values using different discount rates ranging from 9.0% to 13.0%, which were chosen to reflect different assumptions regarding required rates of return of holders or prospective buyers of HSBI common stock. As illustrated in the following tables, the analysis indicated an imputed range of values per share of HSBI common stock of $19.01 to $31.67 when applying multiples of earnings and $17.86 to $31.51 when applying multiples of tangible book value.

13.0%		17.86		19.64		21.43		23.22		25.00		26.79

Piper Sandler also considered and discussed with HSBI’s board of directors how this analysis would be affected by changes in the underlying assumptions, including variations with respect to earnings. To illustrate this impact, Piper Sandler performed a similar analysis, assuming HSBI’s earnings varied from 10% above projections to 10% below projections. This analysis resulted in the following range of per share values for HSBI’s common stock, applying the price to LTM earnings multiples range of 9.00x to 12.75x referred to above and a discount rate of 11.36%.

Piper Sandler also performed an analysis that estimated the net present value per share of FBMS common stock, assuming FBMS performed in accordance with publicly available mean analyst net income and dividend per share estimates for FBMS for the years ending December 31, 2022 and December 31, 2023, as provided by the senior management of FBMS, as well as a long-term annual earnings per share growth rate and estimated dividends per share for FBMS for the years ending December 31, 2024 through December 31, 2026, as provided by the senior management of FBMS. To approximate the terminal value of a share of FBMS common stock at December 31, 2026, Piper Sandler applied price to LTM earnings multiples ranging from 8.0x to 15.5x and multiples of June 30, 2022 tangible book value ranging from 120% to 220%. The terminal values were then discounted to present values using different discount rates ranging from 9.0% to 13.0%, which were chosen to reflect different assumptions regarding required rates of return of holders or prospective buyers of FBMS common stock. As illustrated in the following tables, the analysis indicated an imputed range of values per share of FBMS common stock of $20.37 to $43.44 when applying multiples of earnings and $24.36 to $49.85 when applying multiples of tangible book value.

Piper Sandler also considered and discussed with HSBI’s board of directors how this analysis would be affected by changes in the underlying assumptions, including variations with respect to earnings. To illustrate this impact, Piper Sandler performed a similar analysis assuming FBMS’s earnings varied from 10% above estimates to 10% below estimates. This analysis resulted in the following range of per share values for FBMS common stock, applying the price to LTM earnings multiples range of 8.0x to 15.5x referred to above and a discount rate of 10.31%.

Piper Sandler noted that the net present value analysis is a widely used valuation methodology, but the results of such methodology are highly dependent upon the numerous assumptions that must be made, and the results thereof are not necessarily indicative of actual values or future results.

Pro Forma Transaction Analysis.

Piper Sandler analyzed certain potential pro forma effects of the merger on FBMS assuming the transaction closes December 31, 2022. Piper Sandler utilized the following information and assumptions: (a) internal net income estimates for HSBI for the years ending December 31, 2022 through December 31, 2024 with an estimated net income growth rate for HSBI for the years ending December 31, 2025 and December 31, 2026, as provided by the senior management of FBMS, (b) publicly available mean analyst net income and dividend per share estimates for FBMS for the years ending December 31, 2022 and December 31, 2023, as provided by the senior management of FBMS, as well as a long-term annual earnings per share growth rate and estimated dividends per share for FBMS for the years ending December 31, 2024 through December 31, 2026, as provided by the senior management of FBMS, and (c) certain assumptions relating to transaction expenses, purchase accounting adjustments and cost savings. The analysis indicated that the transaction could be accretive to FBMS’s estimated earnings per share (excluding one-time transaction costs and expenses) in the years ending December 31, 2023 through December 31, 2026 and dilutive to FBMS’s estimated tangible book value per share at December 31, 2022 and through December 31, 2024 and accretive at December 31, 2025 and December 31, 2026.

In connection with this analysis, Piper Sandler considered and discussed with the HSBI’s board of directors how the analysis would be affected by changes in the underlying assumptions, including the impact of final purchase accounting adjustments determined at the closing of the transaction, and noted that the actual results achieved by the combined company may vary from projected results and the variations may be material.

Piper Sandler’s Relationship.

Piper Sandler is acting as HSBI’s financial advisor in connection with the transaction and will receive a fee for such services in an amount equal to 1.20% of the aggregate purchase price, which fee is contingent upon the closing of the merger. At the time of announcement of the transaction, Piper Sandler’s fee was approximately $2.48 million. Piper Sandler also received a $250,000 fee from HSBI upon rendering its opinion, which opinion fee will be credited in full towards the advisory fee which will become payable to Piper Sandler upon closing of the merger. HSBI has also agreed to indemnify Piper Sandler against certain claims and liabilities arising out of Piper Sandler’s engagement and to reimburse Piper Sandler for certain of its out-of-pocket expenses incurred in connection with Piper Sandler’s engagement.

In the two years preceding the date of Piper Sandler’s opinion Piper Sandler did not provide any other investment banking services to HSBI. Piper Sandler did not provide any investment banking services to FBMS in the two years preceding the date of its opinion. In the ordinary course of Piper Sandler’s business as a broker-dealer, Piper Sandler may purchase securities from and sell securities to HSBI and FBMS. Piper Sandler may also actively trade the equity and debt securities of HSBI and FBMS for Piper Sandler’s account and for the accounts of Piper Sandler’s customers.

Opinions of First Bancshares’ Financial Advisors

Opinion of Keefe, Bruyette & Woods, Inc.

First Bancshares engaged Keefe, Bruyette & Woods, Inc., which we refer to as KBW, to render financial advisory and investment banking services to First Bancshares, including an opinion to the First

TABLE OF CONTENTS

Bancshares board of directors as to the fairness, from a financial point of view, to First Bancshares of the exchange ratio in the proposed merger. First Bancshares selected KBW because KBW is a nationally recognized investment banking firm with substantial experience in transactions similar to the merger. As part of its investment banking business, KBW is continually engaged in the valuation of financial services businesses and their securities in connection with mergers and acquisitions.

As part of its engagement, KBW rendered a written opinion, dated July 27, 2022, to the effect that, as of such date and subject to the procedures followed, assumptions made, matters considered, and qualifications and limitations on the review undertaken by KBW as set forth in such opinion, the exchange ratio in the proposed merger was fair, from a financial point of view, to First Bancshares.

The description of the opinion set forth herein is qualified in its entirety by reference to the full text of the opinion, which is attached as Annex C to this document and is incorporated herein by reference, and describes the procedures followed, assumptions made, matters considered, and qualifications and limitations on the review undertaken by KBW in preparing the opinion.

KBW’s opinion speaks only as of the date of the opinion. The opinion was for the information of, and was directed to, the First Bancshares board (in its capacity as such) in connection with its consideration of the financial terms of the merger. The opinion addressed only the fairness, from a financial point of view, of the exchange ratio in the merger to First Bancshares. It did not address the underlying business decision of First Bancshares to engage in the merger or enter into the merger agreement or constitute a recommendation to the First Bancshares board in connection with the merger, and it does not constitute a recommendation to any holder of First Bancshares common stock or any shareholder of any other entity as to how to vote in connection with the merger or any other matter, nor does it constitute a recommendation as to whether or not any such shareholder should enter into a voting, shareholders’, affiliates’ or other agreement with respect to the merger or exercise any dissenters’ or appraisal rights that may be available to such shareholder.

KBW’s opinion was reviewed and approved by KBW’s Fairness Opinion Committee in conformity with its policies and procedures established under the requirements of Rule 5150 of the Financial Industry Regulatory Authority.

In connection with the opinion, KBW reviewed, analyzed and relied upon material bearing upon the financial and operating condition of First Bancshares and HSBI and bearing upon the merger, including, among other things:

•

a draft of the Agreement dated July 26, 2022 (the most recent draft made available to KBW);

•

the audited financial statements and the Annual Reports on Form 10-K for the three fiscal years ended December 31, 2021 of First Bancshares;

•

the unaudited quarterly financial statements and Quarterly Report on Form 10-Q for the quarter ended March 31, 2022 of First Bancshares;

•

certain preliminary and unaudited quarterly financial results for the quarter ended June 30, 2022 of First Bancshares (provided by First Bancshares);

•

the audited financial statements for the three fiscal years ended December 31, 2021 of HSBI;

the unaudited quarterly financial statements for the quarter ended March 31, 2022 of HSBI;

•

certain other interim reports and other communications of First Bancshares and HSBI to their respective shareholders; and

TABLE OF CONTENTS

•

other financial information concerning the respective businesses and operations of First Bancshares and HSBI furnished to KBW by First Bancshares and HSBI or which KBW was otherwise directed to use for purposes of KBW’s analysis.

KBW’s consideration of financial information and other factors that it deemed appropriate under the circumstances or relevant to its analyses included, among others, the following:

•

the historical and current financial position and results of operations of First Bancshares and HSBI;

•

the assets and liabilities of First Bancshares and HSBI;

•

the nature and terms of certain other merger transactions and business combinations in the banking industry;

•

a comparison of certain financial and stock market information of First Bancshares and HSBI with similar information for certain other companies, the securities of which were publicly traded;

•

financial and operating forecasts and projections of HSBI with respect to fiscal years 2022, 2023 and 2024 that were prepared by HSBI management, provided to and discussed with KBW by such management, and used and relied upon by KBW based on such discussions, at the direction of First Bancshares management and with the consent of the First Bancshares board;

•

publicly available consensus “street estimates” of First Bancshares, as well as assumed First Bancshares and HSBI long-term growth rates provided to KBW by First Bancshares management, all of which information was discussed with KBW by such management and used and relied upon by KBW at the direction of such management and with the consent of the First Bancshares board;

•

pro forma balance sheet and capital data of First Bancshares as of June 30, 2022, as adjusted for First Bancshares’s then pending acquisition of Beach Bancorp, Inc., that was prepared by First Bancshares management, provided to and discussed with KBW by such management and used and relied upon by KBW at the direction of First Bancshares management and with the consent of the First Bancshares board; and

•

estimates regarding certain pro forma financial effects of the merger on First Bancshares (including without limitation the cost savings and related expenses expected to result or be derived from the merger) that were prepared by First Bancshares management, provided to and discussed with KBW by such management, and used and relied upon by KBW at the direction of such management and with the consent of the First Bancshares board.

KBW also performed such other studies and analyses as it considered appropriate and took into account its assessment of general economic, market and financial conditions and its experience in other transactions, as well as its experience in securities valuation and knowledge of the banking industry generally. KBW also participated in discussions held by the managements of First Bancshares and HSBI regarding the past and current business operations, regulatory relations, financial condition and future prospects of their respective companies and such other matters as KBW deemed relevant to its inquiry.

In conducting its review and arriving at its opinion, KBW relied upon and assumed the accuracy and completeness of all of the financial and other information that was provided to or discussed with it or that was publicly available and KBW did not independently verify the accuracy or completeness of any such information or assume any responsibility or liability for such verification, accuracy or completeness. KBW relied, with the consent of First Bancshares, upon the management of HSBI as to the reasonableness and achievability of the financial and operating forecasts and projections of HSBI with respect to fiscal years 2022, 2023 and 2024 as referred to above (and the assumptions and bases therefor), and KBW assumed that such forecasts and projections were reasonably prepared and represented the best currently available estimates and judgments of such management and that such forecasts and projections would be realized in the amounts and in the time periods estimated by such management. KBW further relied upon the management of First Bancshares as to the reasonableness and achievability of the publicly available consensus “street estimates” of First Bancshares, the assumed First Bancshares and HSBI long-term growth rates, and the estimates regarding certain pro forma financial effects of the merger on First Bancshares (including, without limitation, the cost savings and related expenses expected to result or be derived from the merger), all as referred to above (and the assumptions and bases for all such information), and KBW

TABLE OF CONTENTS

assumed that all such information was reasonably prepared and represented, or in the case of the publicly available consensus “street estimates” of First Bancshares referred to above that such estimates were consistent with, the best currently available estimates and judgments of First Bancshares management and that the forecasts, projections and estimates reflected in such information would be realized in the amounts and in the time periods estimated.

It is understood that the portion of the foregoing financial information of First Bancshares and HSBI that was provided to KBW was not prepared with the expectation of public disclosure and that all of the foregoing financial information, including the publicly available consensus “street estimates” of First Bancshares referred to above, was based on numerous variables and assumptions that are inherently uncertain (including, without limitation, factors related to general economic and competitive conditions, and in particular, assumptions regarding the ongoing COVID-19 pandemic) and, accordingly, actual results could vary significantly from those set forth in such information. KBW assumed, based on discussions with the respective managements of First Bancshares and HSBI and with the consent of the First Bancshares board, that all such information provided a reasonable basis upon which KBW could form its opinion and KBW expressed no view as to any such information or the assumptions or bases therefor. Among other things, such information assumed that the ongoing COVID-19 pandemic could have an adverse impact, which was assumed to be limited, on First Bancshares and HSBI. KBW relied on all such information without independent verification or analysis and did not in any respect assume any responsibility or liability for the accuracy or completeness thereof.

KBW also assumed that there were no material changes in the assets, liabilities, financial condition, results of operations, business or prospects of either First Bancshares or HSBI since the date of the last financial statements of each such entity that were made available to KBW. KBW is not an expert in the independent verification of the adequacy of allowances for loan and lease losses and KBW assumed, without independent verification and with First Bancshares’s consent, that the aggregate allowances for loan and lease losses for each of First Bancshares and HSBI are adequate to cover such losses. In rendering its opinion, KBW did not make or obtain any evaluations or appraisals or physical inspection of the property, assets or liabilities (contingent or otherwise) of First Bancshares or HSBI, the collateral securing any of such assets or liabilities, or the collectability of any such assets, nor did KBW examine any individual loan or credit files, nor did it evaluate the solvency, financial capability or fair value of First Bancshares or HSBI under any state or federal laws, including those relating to bankruptcy, insolvency or other matters. Estimates of values of companies and assets do not purport to be appraisals or necessarily reflect the prices at which companies or assets may actually be sold. Such estimates are inherently subject to uncertainty and should not be taken as KBW’s view of the actual value of any companies or assets.

KBW assumed, in all respects material to its analyses:

•

the merger and any related transactions (including, without limitation, the bank merger) would be completed substantially in accordance with the terms set forth in the merger agreement (the final terms of which KBW assumed would not differ in any respect material to its analyses from the draft version of the merger agreement reviewed by KBW and referred to above) with no adjustments to the exchange ratio and with no other consideration or payments in respect of HSBI common stock;

•

the representations and warranties of each party in the merger agreement and in all related documents and instruments referred to in the merger agreement were true and correct;

•

each party to the merger agreement and all related documents would perform all of the covenants and agreements required to be performed by such party under such documents;

•

there were no factors that would delay or subject to any adverse conditions, any necessary regulatory or governmental approval for the merger or any related transactions and all conditions to the completion of the merger and any related transactions would be satisfied without any waivers or modifications to the merger agreement or any of the related documents; and

•

in the course of obtaining the necessary regulatory, contractual, or other consents or approvals for the merger and any related transactions, no restrictions, including any divestiture requirements, termination or other payments or amendments or modifications, would be imposed that would have a material adverse effect on the future results of operations or financial condition of First

TABLE OF CONTENTS

Bancshares, HSBI or the pro forma entity, or the contemplated benefits of the merger, including without limitation the cost savings and related expenses expected to result or be derived from the merger.

KBW assumed that the merger would be consummated in a manner that complies with the applicable provisions of the Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as amended, and all other applicable federal and state statutes, rules and regulations. KBW was further advised by representatives of First Bancshares that First Bancshares relied upon advice from its advisors (other than KBW) or other appropriate sources as to all legal, financial reporting, tax, accounting and regulatory matters with respect to First Bancshares, HSBI, the merger and any related transaction, and the merger agreement. KBW did not provide advice with respect to any such matters.

KBW’s opinion addressed only the fairness, from a financial point of view, as of the date of such opinion, of the exchange ratio in the merger to First Bancshares. KBW expressed no view or opinion as to any other terms or aspects of the merger or any term or aspect of any related transaction (including the bank merger), including without limitation, the form or structure of the merger or any such related transaction, any consequences of the merger or any such related transaction to First Bancshares, its shareholders, creditors or otherwise, or any terms, aspects, merits or implications of any employment, voting, support, lock-up, shareholder or other agreements, arrangements or understandings contemplated or entered into in connection with the merger, any such related transaction, or otherwise. KBW’s opinion was necessarily based upon conditions as they existed and could be evaluated on the date of such opinion and the information made available to KBW through such date. There has been and is currently significant volatility in the stock and other financial markets arising from global tensions, economic uncertainty and the effects of the COVID-19 pandemic, including the effect of evolving governmental interventions and non-interventions. Developments subsequent to the date of KBW’s opinion may have affected, and may affect, the conclusion reached in KBW’s opinion and KBW did not and does not have an obligation to update, revise or reaffirm its opinion. KBW’s opinion did not address, and KBW expressed no view or opinion with respect to:

•

the underlying business decision of First Bancshares to engage in the merger or enter into the merger agreement;

•

the relative merits of the merger as compared to any strategic alternatives that are, have been or may be available to or contemplated by First Bancshares or the First Bancshares board;

•

any business, operational or other plans with respect to HSBI or the pro forma entity that may be currently contemplated by First Bancshares or the First Bancshares board or that may be implemented by First Bancshares or the First Bancshares board subsequent to the closing of the merger;

•

the fairness of the amount or nature of any compensation to any of First Bancshares’s officers, directors or employees, or any class of such persons, relative to any compensation to the holders of First Bancshares common stock or relative to the exchange ratio;

•

the effect of the merger or any related transaction on, or the fairness of the consideration to be received by, holders of any class of securities of First Bancshares, HSBI or any other party to any transaction contemplated by the merger agreement;

•

any adjustment (as provided in the merger agreement) to the exchange ratio assumed to be paid in the merger for purposes of KBW’s opinion;

•

the actual value of First Bancshares common stock to be issued in connection with the merger;

•

the prices, trading range or volume at which First Bancshares common stock or HSBI common stock would trade following the public announcement of the merger or the prices, trading range or volume at which First Bancshares common stock would trade following the consummation of the merger;

•

any advice or opinions provided by any other advisor to any of the parties to the merger or any other transaction contemplated by the merger agreement; or

•

any legal, regulatory, accounting, tax or similar matters relating to First Bancshares, HSBI, any of their respective shareholders, or relating to or arising out of or as a consequence of the merger or any

TABLE OF CONTENTS

other related transaction, including whether or not the merger would qualify as a tax-free reorganization for United States federal income tax purposes.

In performing its analyses, KBW made numerous assumptions with respect to industry performance, general business, economic, market and financial conditions and other matters, which are beyond the control of KBW, First Bancshares and HSBI. Any estimates contained in the analyses performed by KBW are not necessarily indicative of actual values or future results, which may be significantly more or less favorable than suggested by these analyses. Additionally, estimates of the value of businesses or securities do not purport to be appraisals or to reflect the prices at which such businesses or securities might actually be sold. Accordingly, these analyses and estimates are inherently subject to substantial uncertainty. In addition, the KBW opinion was among several factors taken into consideration by the First Bancshares board in making its determination to approve the merger agreement and the merger. Consequently, the analyses described below should not be viewed as determinative of the decision of the First Bancshares board with respect to the fairness of the exchange ratio. The type and amount of consideration payable in the merger were determined through negotiation between First Bancshares and HSBI and the decision of First Bancshares to enter into the merger agreement was solely that of the First Bancshares board.

The following is a summary of the material financial analyses performed by KBW in connection with its opinion. The summary is not a complete description of the financial analyses underlying the opinion or the presentation provided by KBW to the First Bancshares board, but summarizes the material analyses performed in connection with such opinion. The financial analyses summarized below include information presented in tabular format. The tables alone do not constitute a complete description of the financial analyses. The preparation of a fairness opinion is a complex analytic process involving various determinations as to appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances. Therefore, a fairness opinion is not readily susceptible to partial analysis or summary description. In arriving at its opinion, KBW did not attribute any particular weight to any analysis or factor that it considered, but rather made qualitative judgments as to the significance and relevance of each analysis and factor. Accordingly, KBW believes that its analyses and the summary of its analyses must be considered as a whole and that selecting portions of its analyses and factors or focusing on the information presented below in tabular format, without considering all analyses and factors or the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of the process underlying its analyses and opinion.

For purposes of the financial analyses described below, KBW utilized an implied transaction value for the proposed merger of $28.64 per share of outstanding HSBI common stock, or $207.5 million in the aggregate (inclusive of the implied value of in-the-money options to purchase shares of HSBI common stock), based on the 0.965x exchange ratio in the proposed merger and the closing price of First Bancshares common stock on July 26, 2022 of $29.68. In addition to the financial analyses described below, KBW reviewed with the First Bancshares board of directors for informational purposes, among other things, implied transaction multiples for the proposed merger (based on the implied transaction value for the proposed merger of $207.5 million in the aggregate) of 12.8x HSBI’s estimated 2022 net income and 10.4x HSBI’s estimated 2023 net income using financial and operating forecasts and projections of HSBI provided by HSBI management.

First Bancshares Selected Companies Analysis. Using publicly available information, KBW compared the financial performance, financial condition and market performance of First Bancshares to 16 selected major exchange-traded banks that were headquartered in Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana, Mississippi, North Carolina, South Carolina, Tennessee, Virginia or West Virginia with total assets between $5.0 billion and $20.0 billion. Live Oak Bancshares, Inc. was excluded from the selected companies because it is a digital, cloud-based bank.

The selected companies were as follows (shown by column in descending order of total assets):

	Atlantic Union Bancshares Corporation			First Bancorp
	Trustmark Corporation			Amerant Bancorp Inc.
	WesBanco, Inc.			Origin Bancorp, Inc.
	Renasant Corporation			Stock Yards Bancorp, Inc.

	TowneBank			City Holding Company
	ServisFirst Bancshares, Inc.			Republic Bancorp, Inc.
	FB Financial Corporation			Community Trust Bancorp, Inc.
	Seacoast Banking Corporation of Florida			Business First Bancshares, Inc.

To perform this analysis, KBW used profitability and other financial information for the latest 12 months (“LTM”) or the most recent completed fiscal quarter (“MRQ”) available or as of the end of such periods and market price information as of July 26, 2022. KBW also used 2022 and 2023 earnings per share (“EPS”) estimates taken from publicly available consensus “street” estimates for First Bancshares and the selected companies. Data necessary to calculate the CET1 Ratio and the Total Capital Ratio was unreported for one of the selected companies. Certain financial data presented in the tables below may not correspond to the data presented in First Bancshares’s historical financial statements, or the data presented under the section “The Merger — Opinion of HSBI’s Financial Advisor” or under the section “The Merger — Opinions of First Bancshares’ Financial Advisors — Opinion of D.A. Davidson,” as a result of the different periods, assumptions and methods used to compute the financial data presented.

For each selected transaction, KBW derived the following implied transaction statistics, in each case based on the transaction consideration value paid for the acquired company and using financial data based on the acquired company’s then latest publicly available financial statements at the announcement of the

TABLE OF CONTENTS

respective transaction, information taken from the acquiror’s investor presentation regarding the respective transaction and, to the extent publicly available, the one-year forward net income consensus “street estimate” for the acquired company at the announcement of the respective transaction:

•

Price per common share to tangible book value per share of the acquired company (in the case of selected transactions involving a private acquired company, this transaction statistic was calculated as total transaction consideration divided by total tangible common equity);

•

Pay-to-trade ratio (calculated as the price to tangible book value multiple paid in the respective transaction divided by the acquiror’s standalone closing stock price to tangible book value multiple) in the case of 18 selected transactions;

•

Total transaction consideration to LTM core net income of the acquired company;

•

Total transaction consideration to estimated one-year forward net income of the acquired company in case of the three selected transactions in which consensus “street estimates” for the acquired company were available at announcement; and

•

Tangible equity premium to core deposits (total deposits less time deposits greater than $100,000) of the acquired company, referred to as core deposit premium.

KBW also reviewed the price per common share paid for the acquired company for the 10 selected transactions in which the acquired company was publicly traded as a premium to the closing price of the acquired company one day prior to the announcement of the respective transaction (expressed as a percentage and referred to as the one-day market premium). The above transaction statistics for the selected transactions were compared with the corresponding transaction statistics for the proposed merger based on the implied transaction value for the proposed merger of $28.64 per outstanding share of HSBI common stock, or $207.5 million in the aggregate, and using historical financial information for HSBI as of or for the 12 months ended June 30, 2022, financial and operating forecasts and projections of HSBI with respect to fiscal year 2023 provided by HSBI management and the closing price of HSBI common stock on July 26, 2022.The results of the analysis are set forth in the following (excluding the impact of the LTM core net income multiple for one of the selected transactions, which multiple was considered not meaningful because it was greater than 35.0x):

No company or transaction used as a comparison in the above selected transaction analysis is identical to HSBI or the proposed merger. Accordingly, an analysis of these results is not mathematical. Rather, it involves complex considerations and judgments concerning differences in financial and operating characteristics of the companies involved.

Relative Contribution Analysis. KBW analyzed the relative standalone contribution of First Bancshares and HSBI to various pro forma balance sheet and income statement items and the combined market capitalization of the combined entity. This analysis did not include purchase accounting adjustments or cost savings. To perform this analysis, KBW used (i) pro forma balance sheet and income statement data as of June 30, 2022 for First Bancshares (adjusted for First Bancshares’s then pending acquisition of Beach Bancorp, Inc.) provided by First Bancshares management and historical balance sheet and income

TABLE OF CONTENTS

statement data as of June 30, 2022 for HSBI, (ii) publicly available consensus “street estimates” of First Bancshares, (iii) financial and operating forecasts and projections of HSBI provided by HSBI management, and (iv) market price data as of July 26, 2022. The results of KBW’s analysis are set forth in the following table, which also compares the results of KBW’s analysis with the implied pro forma ownership percentages of First Bancshares and HSBI shareholders in the combined company based on the 0.965x exchange ratio provided for in the merger agreement:

	First Bancshares % of Total		HSBI % of Total
Ownership at 0.965x merger exchange ratio:		78%		22%
Balance Sheet:
Assets		79%		21%
Gross Loans Held for Investment		76%		24%

Pro Forma Financial Impact Analysis. KBW performed a pro forma financial impact analysis that combined projected income statement and balance sheet information of First Bancshares and HSBI. Using (i) closing balance sheet estimates assumed as of December 31, 2022 for First Bancshares (pro forma for First Bancshares’s acquisition of Beach Bancorp, Inc.) taken from publicly available consensus “street estimates” of First Bancshares, and closing balance sheet estimates assumed as of December 31, 2022 for HSBI provided by HSBI management, (ii) publicly available consensus “street estimates” of First Bancshares and assumed First Bancshares long-term growth rates provided by First Bancshares management, (iii) financial and operating forecasts and projections of HSBI provided by HSBI management, and (iv) pro forma assumptions (including, without limitation, the cost savings and related expenses expected to result from the merger as well as certain purchase accounting adjustments and other merger-related adjustments and restructuring charges assumed with respect thereto) provided by First Bancshares management, KBW analyzed the estimated financial impact of the merger on certain projected financial results. This analysis indicated that the merger could be accretive to each of First Bancshares’s 2023 estimated EPS and 2024 estimated EPS and could be dilutive to First Bancshares’s estimated tangible book value per share at closing assumed as of December 31, 2022. Furthermore, the analysis indicated that, pro forma for the merger, each of First Bancshares’s tangible common equity to tangible assets ratio, Tier 1 Leverage Ratio, Common Equity Tier 1 Ratio, Tier 1 Risk-Based Capital Ratio and Total Risk-Based Capital Ratio could be lower at closing assumed as of December 31, 2022. For all of the above analysis, the actual results achieved by First Bancshares following the merger may vary from the projected results, and the variations may be material.

First Bancshares Dividend Discount Model Analysis. KBW performed a dividend discount model analysis to estimate a range for the implied equity value of First Bancshares. In this analysis, KBW used

TABLE OF CONTENTS

publicly available consensus “street estimates” of First Bancshares and assumed First Bancshares long-term growth rates provided by First Bancshares management, and KBW assumed discount rates ranging from 9.0% to 13.0%. The range of values was derived by adding (i) the present value of the implied future excess capital available for dividends that First Bancshares could generate over the period from July 1, 2022 through December 31, 2027 and (ii) the present value of First Bancshares’s implied terminal value at the end of such period. KBW assumed that First Bancshares would maintain a tangible common equity to tangible assets ratio of 8.00% and First Bancshares would retain sufficient earnings to maintain that level. In calculating the terminal value of First Bancshares, KBW applied a range of 8.0x to 12.0x First Bancshares’s estimated 2028 earnings. This dividend discount model analysis resulted in a range of implied values per share of First Bancshares common stock of $22.92 to $37.80.

The dividend discount model analysis is a widely used valuation methodology, but the results of such methodology are highly dependent on the assumptions that must be made, including asset and earnings growth rates, terminal values, and discount rates. The analysis did not purport to be indicative of the actual values or expected values of First Bancshares or the pro forma combined company.

HSBI Dividend Discount Model Analysis. KBW performed a dividend discount model analysis to estimate a range for the implied equity value of HSBI, taking into account the cost savings and related expenses expected to result from the merger as well as the HSBI restructuring charge assumed with respect thereto. In this analysis, KBW used financial and operating forecasts and projections relating to the earnings and assets of HSBI with respect to fiscal years 2022, 2023 and 2024 provided by HSBI management, assumed HSBI long-term growth rates provided by First Bancshares management and assumptions regarding cost savings and related expenses expected to result from the merger and the HSBI restructuring charge with respect thereto provided by First Bancshares management, and KBW assumed discount rates ranging from 12.0% to 16.0%. The range of values was derived by adding (i) the present value of the implied future excess capital available for dividends that HSBI could generate over the period from January 1, 2023 through December 31, 2027 (assuming the HSBI restructuring charge) and (ii) the present value of HSBI’s implied terminal value at the end of such period, in each case applying estimated cost savings and related expenses. KBW assumed that HSBI would maintain a tangible common equity to tangible assets ratio of 8.00% and HSBI would retain sufficient earnings to maintain that level. In calculating the terminal value of HSBI, KBW applied a range of 7.0x to 11.0x HSBI’s estimated 2028 earnings (inclusive of estimated cost savings and related expenses). This dividend discount model analysis resulted in a range of implied values per share of HSBI common stock, taking into account the cost savings and related expenses expected to result from the merger as well as the HSBI restructuring charge assumed with respect thereto, of $30.86 to $49.37.

Miscellaneous. KBW acted as financial advisor to First Bancshares in connection with the proposed merger and did not act as an advisor to or agent of any other person. As part of its investment banking business, KBW is continually engaged in the valuation of bank and bank holding company securities in connection with acquisitions, negotiated underwritings, secondary distributions of listed and unlisted securities, private placements and valuations for various other purposes. As specialists in the securities of banking companies, KBW has experience in, and knowledge of, the valuation of banking enterprises. Further to an existing sales and trading relationship of KBW with First Bancshares, and otherwise in the ordinary course of KBW and its affiliates’ broker-dealer businesses, KBW and its affiliates may from time to time purchase securities from, and sell securities to, First Bancshares and HSBI. In addition, as market makers in securities, KBW and its affiliates may from time to time have a long or short position in, and buy or sell, debt or equity securities of First Bancshares or HSBI for its and their own respective accounts and for the accounts of its and their respective customers and clients.

Pursuant to the KBW engagement agreement, First Bancshares has agreed to pay KBW a cash fee of $2,000,000, $350,000 of which became payable with the rendering of KBW’s opinion, and the balance of which is contingent upon the consummation of the merger. First Bancshares also agreed to reimburse KBW for reasonable out-of-pocket expenses and disbursements incurred in connection with its engagement and to indemnify KBW against certain liabilities relating to or arising out of KBW’s engagement or KBW’s role

in connection therewith. In addition to the present engagement, in the two years preceding the date of KBW’s opinion, KBW provided investment banking and financial advisory services to First Bancshares and received compensation for such services. KBW acted as lead placement agent to First Bancshares in connection with its September 2020 offering of subordinated debt. KBW currently acts as broker for First Bancshares’ stock repurchase plan. In connection with acting as lead placement agent in First Bancshares’s September 2020 offering and broker for First Bancshares’ stock repurchase plan, KBW received fees from First Bancshares of approximately $655,000 in the aggregate in the two years preceding the date of KBW’s opinion. In the two years preceding the date of KBW’s opinion, KBW did not provide investment banking or financial advisory services to HSBI. KBW may in the future provide investment banking and financial advisory services to First Bancshares or HSBI and receive compensation for such services.

Opinion of D.A. Davidson

On July 19, 2022, First Bancshares entered into an engagement agreement with D.A. Davidson to render financial advisory services to First Bancshares. As part of its engagement, D.A. Davidson agreed to provide First Bancshares’ board of directors with an opinion as to the fairness, from a financial point of view, of the Merger Consideration in the Merger.

Davidson does not express any view on, and its opinion does not address, any other term or aspect of the Agreement or Merger (including, without limitation, the form or structure of the Merger) or any term or aspect of any other agreement or instrument contemplated by the Agreement or entered into in connection with the Merger, or as to the underlying business decision by First Bancshares to engage in the Merger.

Net Present Value Analysis

Net Present Value Analysis for HSBI

D.A. Davidson performed an analysis that estimated the net present value per share of HSBI Stock under various circumstances. The financial projections for HSBI [are based on D.A. Davidson assumptions], as discussed with and approved for D.A. Davidson’s use by First Bancshares management. To approximate the terminal value of HSBI Stock at December 31, 2027, D.A. Davidson applied price to earnings multiples of 9.0x to 15.0x and multiples of tangible book value ranging from 70% to 190%. The income streams and terminal values were then discounted to present values using different discount rates ranging from 11.0% to 15.0% chosen to reflect different assumptions regarding required rates of return of holders or prospective buyers of HSBI’s Stock. In evaluating the discount rate, D.A. Davidson used industry standard methods of

adding the current risk-free rate, which is based on the Kroll normalized risk-free rate, the published Kroll Industry Equity Risk Premium and the published Kroll Size Premium.

The net present value analysis is a widely used valuation methodology, but the results of such methodology are highly dependent upon the numerous assumptions that must be made, and the results thereof are not necessarily indicative of actual values or future results.

As illustrated in the following tables, the analysis indicates a range of $15.85 to $31.54 per share of HSBI Stock when applying the price to earnings multiples to the financial projections and $12.77 to $41.39 per share of HSBI Stock when applying the multiples of tangible book value to the financial projections.

As illustrated in the following table, the analysis resulted in the following range of and $20.68 to $47.32 per share of First Bancshares Common Stock, using the price to earnings multiples of 9.0x to 15.0x and a discount rate of 12.0%.

Financial Impact Analysis

D.A. Davidson performed pro forma merger analyses that combined projected income statement and balance sheet information of First Bancshares and HSBI. Assumptions regarding the accounting treatment, acquisition adjustments, cost savings and revenue enhancements were used to calculate the financial impact that the Merger would have on certain projected financial results of HSBI. The financial projections for First Bancshares are based on publicly available analyst earnings estimates for the years ended December 31, 2022 through December 31, 2024 and an estimated long-term growth rate for the years thereafter, as discussed with and approved for D.A. Davidson’s use by First Bancshares management. The financial projections for HSBI are based on certain financial projections for the years ended December 31, 2022 through December 31, 2024 based on D.A. Davidson assumptions and an estimated long-term growth rate for the years thereafter, as discussed with and approved for D.A. Davidson’s use by First Bancshares management. This analysis indicated that the Merger is expected to be accretive to First Bancshares’ estimated earnings per share beginning in 2023, after excluding non-recurring Merger-related expenses. The analysis also indicated that the Merger is expected to be dilutive to tangible book value per share for First Bancshares and that First Bancshares would maintain capital ratios in excess of those required for First Bancshares to be considered well-capitalized under existing regulations. For all of the above analyses, the actual results achieved by First Bancshares and HSBI prior to and following the Merger will vary from the projected results, and the variations may be material.

Other Information

D.A. Davidson prepared its analyses for purposes of providing its opinion to First Bancshares’ board of directors as to the fairness, from a financial point of view, of the Merger Consideration in the Merger. The analyses do not purport to be appraisals or necessarily reflect the prices at which businesses or securities actually may be sold. Analyses based upon projections of future results are not necessarily indicative of actual future results, which may be significantly more or less favorable than those suggested by these analyses. Because these analyses are inherently subject to uncertainty, being based upon numerous factors or events

TABLE OF CONTENTS

beyond the control of the parties and their respective advisors, none of First Bancshares, HSBI or D.A. Davidson or any other person assumes responsibility if future results are materially different from those projected.

D.A. Davidson’s opinion was one of many factors considered by First Bancshares’ board of directors in its evaluation of the Merger and should not be viewed as determinative of the views of the board of directors of First Bancshares or management with respect to the Merger or the Merger Consideration.

D.A. Davidson and its affiliates, as part of their investment banking business, are continually engaged in performing financial analyses with respect to businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and other transactions. D.A. Davidson is a full service securities firm engaged, either directly or through its affiliates, in securities trading, investment management, financial planning and benefits counseling, financing and brokerage activities for both companies and individuals. In the ordinary course of these activities, D.A. Davidson and its affiliates may provide such services to First Bancshares, HSBI and their respective affiliates, may actively trade or hold the securities of First Bancshares and HSBI for its own account and for the accounts of its customers and may at any time hold long and short positions of such securities. First Bancshares selected D.A. Davidson as its financial advisor because it is a recognized investment banking firm that has substantial experience in transactions similar to the Merger. Pursuant to a letter agreement executed on July 19, 2022, First Bancshares engaged D.A. Davidson as its financial advisor in connection with the Merger and agreed to pay D.A. Davidson a cash fee of $350,000 concurrently with the rendering of its opinion. First Bancshares has also agreed to reimburse D.A. Davidson for all reasonable out-of-pocket expenses, including fees of counsel, and to indemnify D.A. Davidson and certain related persons against specified liabilities, including liabilities under the federal securities laws, relating to or arising out of its engagement.

D.A. Davidson has not had any other material financial advisory or other material commercial or investment banking relationships with First Bancshares or HSBI during the two years preceding the date of the fairness opinion letter. Additionally, D.A. Davidson may seek to provide investment banking services to the combined company in the future and would expect to receive future compensation.

Certain Unaudited Prospective Financial Information

First Bancshares and HSBI do not as a matter of course make public projections as to future performance, revenues, earnings or other financial results due to, among other reasons, the inherent uncertainty of the underlying assumptions and estimates. However, First Bancshares and HSBI are including in this proxy statement/prospectus certain unaudited prospective financial information for First Bancshares and HSBI that was made available as described below. The inclusion of this information should not be regarded as an indication that any of HSBI, First Bancshares, Piper Sandler, KBW, D.A. Davidson, their respective representatives or any other recipient of this information considered, or now considers, it to be necessarily predictive of actual or future results, or that it should be construed as financial guidance, and it should not be relied on as such.

For purposes of financial analyses performed by each of Piper Sandler and KBW in connection with their respective opinions as described in “The Merger — Opinion of HSBI’s Financial Advisor” and in “The Merger — Opinions of First Bancshares’ Financial Advisors”, each of Piper Sandler and KBW used certain internal financial projections for HSBI for the years ending December 31, 2022 through December 31, 2024, as provided by the senior management of HSBI, and applied an assumed 5% annual long term growth rate to the assets and an 8% annual long term growth rate for net income and earnings per share, in each case as provided by the senior management of First Bancshares, for years ending December 31, 2025 and December 31, 2026. The following table summarizes this unaudited prospective financial information for the years ending December 31, 2022 through December 31, 2024 with respect to HSBI used by each of Piper

For purposes of financial analyses performed by each of Piper Sandler, KBW, and D.A. Davidson in connection with each of their opinions as described in “The Merger — Opinion of HSBI’s Financial Advisor” and in “The Merger — Opinions of First Bancshares’ Financial Advisors”, each of Piper Sandler, KBW, and D.A. Davidson used certain internal financial projections for First Bancshares for the years ending December 31, 2024 through December 31, 2026 derived from applying a 5% annual long term growth rate, in the case of Piper Sander and KBW, and a 3-5% annual long term growth rate, in the case of D.A. Davidson, as provided by the senior management of First Bancshares, to publicly-available analyst estimates for the assets, net income, and earnings, per share of First Bancshares for years ending December 31, 2022 and December 31, 2023.

This information was prepared solely for internal use and is subjective in many respects. While presented with numeric specificity, the unaudited prospective financial information reflects numerous estimates and assumptions with respect to business, economic, market, competition, regulatory and financial conditions and matters specific to the respective businesses of First Bancshares and HSBI, all of which are difficult to predict and many of which are beyond the control of First Bancshares and HSBI. The unaudited prospective financial information reflects both assumptions as to certain business decisions that are subject to change and, in many respects, subjective judgment, and therefore, is susceptible to multiple interpretations and periodic revisions based on actual experience and business developments. No assurance can be given that the unaudited prospective financial information and the underlying estimates and assumptions will be realized. In addition, since the unaudited prospective financial information covers multiple years, such information by its nature becomes subject to greater uncertainty with each successive year. Actual results may differ materially from those set forth above, and important factors that may affect actual results and cause the unaudited prospective financial information to be inaccurate include, but are not limited to, risks and uncertainties relating to First Bancshares’ and HSBI’s respective businesses, industry performance, general business and economic conditions, customer requirements, competition and adverse changes in applicable laws, regulations or rules. For other facts that could cause actual results to differ, please see the sections entitled “Risk Factors” and “Cautionary Statement Regarding Forward-Looking Statements.”

The unaudited prospective financial information appearing above was not prepared with a view toward public disclosure, nor was it prepared with a view toward compliance with GAAP, the prevailing practices in the banking industry, published guidelines of the SEC or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of prospective financial information. In addition, the unaudited prospective financial information requires significant estimates and assumptions that make it inherently less comparable to the similarly titled GAAP measures in First Bancshares’ and HSBI’s respective historical GAAP financial statements. Neither First Bancshares’ nor HSBI’s independent registered public accounting firm, nor any other independent accountants, have compiled, examined or performed any procedures with respect to the unaudited prospective financial information contained in this document, nor have they expressed any opinion or any other form of assurance on such information or its achievability, and assume no responsibility for, and disclaim any association with, the unaudited prospective financial information. The independent registered public accountant reports incorporated by reference in this proxy statement/prospectus relate to historical financial information of each of First Bancshares and HSBI. They do not extend to the unaudited prospective financial information and should not be read to do so.

Furthermore, the unaudited prospective financial information does not take into account any circumstances or events occurring after the date of their preparation. No assurance can be given that, had the unaudited prospective financial information been prepared as of the date of this joint proxy statement/prospectus, similar estimates and assumptions would be used. Neither First Bancshares nor HSBI intends

TABLE OF CONTENTS

to, and expressly disclaims any obligation to, make publicly available any update or other revision to the unaudited prospective financial information to reflect circumstances existing since their preparation or to reflect the occurrence of unanticipated events, even if any or all of the underlying assumptions are shown to be in error, or to reflect changes in general economic or industry conditions. The unaudited prospective financial information does not take into account the possible financial and other effects on First Bancshares and HSBI of the merger and does not attempt to predict or suggest future results of the combined company after giving effect to the merger. The unaudited prospective financial information does not give effect to the merger, including the impact of negotiating or executing the merger agreement, the expenses that may be incurred in connection with completing the merger, the potential synergies that may be achieved by the combined company as a result of the merger, the effect on First Bancshares or HSBI of any business or strategic decision or action that has been or will be taken as a result of the merger agreement having been executed, or the effect of any business or strategic decisions or actions that would likely have been taken if the merger agreement had not been executed, but that were instead altered, accelerated, postponed or not taken in anticipation of the merger. Further, the unaudited prospective financial information does not take into account the effect on First Bancshares or HSBI of any possible failure of the merger to occur. By inclusion of the unaudited prospective financial information in this document, none of First Bancshares, HSBI, Piper Sandler, KBW, D.A. Davidson, or their respective affiliates, associates, officers, directors, advisors, agents or other representatives makes any representation to any shareholder of First Bancshares or HSBI or any other person regarding First Bancshares’ and HSBI’s ultimate performance compared to the information contained in the unaudited prospective financial information or that the projected results will be achieved. The inclusion of the unaudited prospective financial information in this document should not be deemed an admission or representation by First Bancshares or HSBI that it is viewed as material information, particularly in light of the inherent risks and uncertainties associated with such forecasts. The summary of the unaudited prospective financial information included above is not being included to influence your decision whether to vote to approve the merger, but is being provided solely because it was made available to Piper Sandler, KBW, and D.A. Davidson, as discussed above, in connection with the merger.

In light of the foregoing, and considering that the First Bancshares special meeting and the HSBI Special Meeting will each be held several months after the unaudited prospective financial information was prepared, as well as the uncertainties inherent in any forecasted information, shareholders are cautioned not to place unwarranted reliance on such information, and First Bancshares and HSBI urge all shareholders to review First Bancshares’ and HSBI’s financial statements and other information contained elsewhere in this joint proxy statement/prospectus for a description of First Bancshares’ and HSBI’s respective businesses and reported financial results. See “Where You Can Find More Information.” Please see the full text of Piper Sandler’s opinion which is attached as Annex B hereto for more details about the information that Piper Sandler relied on in rendering its opinion. Please see the full text of KBW’s opinion which is attached as Annex C hereto for more details about the information that KBW relied on in rendering its opinion. Please see the full text of D.A. Davidson’s opinion which is attached as Annex D hereto for more details about the information that D.A. Davidson relied on in rendering its opinion.

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 the First Bancshares Bylaws. Likewise, each of the officers and directors of The First Bank 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. First Bancshares has also agreed to evaluate and consider the current directorate of HSBI in good faith, and, upon completion of such evaluation, consider expanding the board of directors of First Bancshares by one position and appointing one current member of the board of directors of HSBI to serve as a director of First Bancshares following the merger.

Interests of HSBI Directors and Executive Officers in the Merger

In the merger, the directors and executive officers of HSBI will receive the same merger consideration for their HSBI shares as the other HSBI shareholders. In considering the recommendation of the HSBI

101

TABLE OF CONTENTS

board of directors that you vote to approve the merger agreement, you should be aware that some of the executive officers and directors of HSBI may have interests in the merger and may have arrangements, as described below, that may be considered to be different from, or in addition to, those of HSBI shareholders generally. HSBI’s board of directors was aware of these interests and considered them, among other matters, in reaching its decision to adopt and approve the merger agreement and to recommend that HSBI shareholders vote in favor of approving the merger agreement. See “The Merger — Background of the Merger” and “The Merger — HSBI’s Reasons for the Merger and Recommendations of the HSBI Board of Directors.” HSBI’s shareholders should take these interests into account in deciding whether to vote “FOR” the proposal to approve the merger agreement. These interests are described in more detail below, and certain of them are quantified in the narrative below.

Offer of New Employment Agreements

Each of Leonard Moreland (a HSBI director and Chief Executive Officer of HSBI), Brad Serff (a HSBI director and President and Chief Banking Officer of Heritage Southeast Bank), Paul Hoerig (Executive Vice President, Chief Risk and Credit Officer of HSBI and Heritage Southeast Bank) and Kathy S. Zovlonsky (Executive Vice President and Chief Administrative Officer of Heritage Southeast Bank) has been offered an employment agreement with The First Bank, which agreements would become effective as of the closing of the merger. Under the terms of the offered agreements, Mr. Moreland would serve as Market President for the State of Georgia, Mr. Serff would serve as Senior Vice President and Senior Lender, Mr. Hoerig would serve as Senior Vice President, Regional Credit Officer and Ms. Zovlonsky would serve as Senior Vice President, Regional Administration. Each offered employment agreement has a term of 18 months commencing with the closingof the merger, and provides for an annual base salary of $315,000, in the case of Mr. Moreland, $275,000, in the case of Mr. Serff, $225,000, in the case of Mr. Hoerig, and $150,000, in the case of Ms. Zovlonsky, as well as participation in The First Bank’s retirement and incentive plans. Each employment agreement also provides for the opportunity to receive an annual bonus (up to a maximum of 10% of base salary) based upon the achievement of performance goals established from year to year by First Bancshares’s Compensation Committee of its Board of Directors, and reimbursement of reasonable business expenses incurred. The employment agreements offered to Mr. Moreland and Mr. Serff also provide that if The First Bank terminates their employment following a “change in control” other than for “cause”, death or disability or they resign from their employment following a change in control for “good reason” (as those terms are defined in their respective employment agreement), then they will be entitled to their accrued base salary up to the date of termination of employment plus a severance amount equal to 2.0 times their then-current base salary payable in a single lump sum, subject to certain limitations under the Internal Revenue Code. The offered employment agreements also include confidentiality provisions and other restrictive covenants whereby the employees would have to agree not to compete for 18 months, or to solicit customers and employees for 3 years, in each case following termination of their employment. The First Bank and the employees are continuing to negotiate the terms of the employment agreements, and may ultimately agree on terms different from those described above, or may not reach agreement.

Change in Control Payments under Existing Employment Agreements

HSBI and Heritage Southeast Bank is currently a party to an employment agreement with certain employees, including each of Mr. Hoerig, Mr. Moreland, Mr. Resch, Mr. Serff, and Ms. Zovlonsky. In connection with the closing of the transaction, each of these employment agreements will be terminated pursuant to a termination agreement and a change of control cash payment will be made to each executive officer. As of the date of this proxy statement, it is anticipated that 8 employment agreements will be terminated for approximately $3.7 million in payments with each payment to a director or executive officer being reflected in the table below.

Supplemental Executive Retirement Plan (“SERP”) Payment and Stock Conversion

Heritage Southeast Bank is currently a party to a SERP agreement with certain employees, including each of Mr. Hoerig, Mr. Moreland, Mr. Resch, Mr. Serff, and Ms. Zovlonsky. These agreements provide for the payment of retirement benefits (in cash and, in certain agreements, stock) to each of the directors or executive officers over a period of 20 years in certain circumstances. Prior to the execution of the merger

102

TABLE OF CONTENTS

agreement, all individual parties to the SERP agreements entered into termination agreements, pursuant to which their respective SERP agreements will be terminated at the effective time of the merger in exchange for a lump sum payment with regard to the cash-based retirement benefit. The total lump sum payments to be paid to the directors and executive officers is approximately $4.5 million with each payment to a director or executive officer being reflected in the table below.

In addition, pursuant to those termination agreements, all obligations to issue any shares of HSBI common stock will be terminated at the effective time of the merger, and each share of HSBI common stock that would otherwise be issuable under the applicable SERP agreement, whether vested or unvested, will be converted into the right to receive 0.965 of a share of First Bancshares common stock, with any fractional share being paid in cash in lieu thereof. Mr. Moreland is the only director or executive officer whose SERP agreement provides for both a cash-based retirement benefit and a stock-based retirement benefit.

Under the terms of the merger agreement and Mr. Moreland’s termination agreement, Mr. Moreland will receive 29,316 shares of First Bancshares common stock shortly following the closing of the merger.

Treatment of Outstanding HSBI Equity Awards

The merger agreement provides that outstanding restricted stock awarded by HSBI pursuant to its equity plans will fully vest at the closing of the merger and automatically be converted into the right to receive a number of First Bancshares common stock equal to the product of (i) the number of HSBI restricted shares subject to such award multiplied by (ii) 0.965, with cash being paid in lieu of any fractional share. The merger agreement also provides that, at the time of closing, each stock option awarded under the HSBI equity plans will be converted into the right to receive a cash payment equal to the product of (A) the excess, if any, of (1) the product of (x) 0.965, multiplied by (y) $29.68, over (2) the per share exercise price of the HSBI option prior to the closing of the merger, multiplied by (B) the number of shares of HSBI common stock subject to such HSBI option prior to the closing of the merger, rounded up to the nearest cent.

Quantification of Payments

The table below sets forth the estimated amount of payments and benefits that each of HSBI’s directors and executive officers would receive in connection with the merger, assuming that the merger were consummated on December 31, 2022. The amounts in the table are based on multiple assumptions that may or may not actually occur or be accurate on the relevant date, including the assumptions described in the footnotes to the table. The amounts below do not reflect compensation actions that may occur after the date of this proxy statement but before the effective time of the merger. In addition, consistent with SEC guidance, the amounts below do not take into account the impact of the new employment agreements between The First Bank and certain of the executive officers. As a result of the foregoing assumptions, the actual amounts, if any, to be received by HSBI’s directors and executive officers may materially differ from the amounts set forth below.

280G Proposal

As provided herein, if the 280G proposal is not approved by the holders of more than 75% of the outstanding shares of HSBI common stock (excluding shares held by Mr. Serff and certain related parties), the total payments to Mr. Serff are subject to reduction. See See “280G Proposal” for a more detailed description.

Indemnification and Insurance

As described under “The Merger Agreement — Indemnification and Directors’ and Officers’ Insurance,” for a period of six years after the effective time of the merger, First Bancshares will indemnify and defend the present and former directors, officers and employees of HSBI and its subsidiaries against claims pertaining to matters occurring at or prior to the closing of the merger to the fullest extent permitted by law. First Bancshares also has agreed, for a period of no less than six years after the effective time of the merger, to provide coverage to present and former directors and officers of HSBI pursuant to HSBI’s existing directors’ and officers’ liability insurance. This insurance policy may be substituted, but must contain at least the same coverage and amounts, and contain terms no less advantageous than the coverage currently provided by HSBI. In no event shall First Bancshares be required to expend for the tail insurance an aggregate premium amount in excess of 250% of the current annual premiums paid by HSBI for such insurance.

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, HSBI 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, approvals of the Federal Reserve Board and Mississippi Department. First Bancshares and/or HSBI have filed applications, waiver requests and notifications to obtain the required regulatory approvals or waivers.

Federal Reserve Board

The merger of HSBI 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

104

TABLE OF CONTENTS

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 anticipates filing a written request that the Federal Reserve Board waive the application requirements of the BHC Act with regard to its acquisition of HSBI.

The merger of Heritage Southeast Bank with and into The First Bank will be subject to approval by the Federal Reserve Board under Section 18(c) of the Federal Deposit Insurance Act (which we refer to as the “Bank Merger Act”). In evaluating an application filed under the Bank Merger Act, the Federal Reserve Board considers: (1) the competitive impact of the transaction, (2) the financial and managerial resources of the depository institutions party to the bank merger and future prospects of the resulting institution, (3) the convenience and needs of the communities to be served, (4) the depository institutions’ effectiveness in combating money-laundering activities and (5) the risk to the stability of the United States banking and financial system. The First’s establishment and operation of branches at Heritage Southeast Bank’s existing branch locations is also subject to approval under Section 9 of the Federal Reserve Act. In considering an application under Bank Merger Act, the Federal Reserve Board also reviews the records of performance of the relevant insured depository institutions under the CRA. The First anticipates filing an application with the Federal Reserve Board under the Bank Merger Act requesting approval of the bank merger.

Mississippi Department of Banking and Consumer Finance

Certain of the transactions contemplated by the merger agreement are subject to approval by the Mississippi Department of Banking and Consumer Finance, or Mississippi Department pursuant to Section 81-5-85 of the Mississippi Code (Miss. Code Ann § 81-5-85). In evaluating an application filed under Section 81-5-85, the Mississippi Department considers criteria essentially similar to the criteria that the FDIC uses in considering applications under the Bank Merger Act. In addition, First Bancshares will file articles of merger with the Mississippi Department and the Mississippi Secretary of State. The First has filed an application with the Mississippi Department pursuant to Section 81-5-85 requesting approval of the bank merger.

Georgia Department of Banking and Finance

To complete the merger, First Bancshares and The First are required to submit an application to, and receive approval from, the Georgia Department. The Georgia Department will review the application to determine whether the merger and the bank merger comply with Georgia law. The First anticipates filing an application with the Georgia Department approval of the bank merger.

First Bancshares and HSBI 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 HSBI 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 HSBI 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 HSBI 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 HSBI will use their respective commercially reasonable efforts to resolve any

105

TABLE OF CONTENTS

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.

Neither First Bancshares nor HSBI 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 of the Merger

The following is a general discussion of the material U.S. federal income tax consequences of the merger to “U.S. holders” (as defined below) of HSBI stock that exchange their shares for the merger consideration. The following discussion is based upon the Code, the U.S. Treasury regulations promulgated thereunder, judicial and administrative authorities, rulings, and decisions, all as in effect on the date of this joint proxy statement/prospectus and all of which are subject to differing interpretations by the Internal Revenue Servivce (the “IRS”) or the courts. These authorities may change, possibly with retroactive effect, and any such change could affect the accuracy of the statements and conclusions set forth in this discussion.

This discussion applies only to U.S. holders of shares of HSBI stock who hold such shares as a capital asset within the meaning of Section 1221 of the Code (generally, property held for investment). For purposes of this discussion, the term “U.S. holder” means a beneficial owner of HSBI stock that is for U.S. federal income tax purposes (1) an individual citizen or resident of the United States, (2) a corporation, or an entity treated as a corporation, created or organized in or under the laws of the United States, any state thereof or the District of Columbia, (3) a trust if (a) 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 (b) such trust has a valid election in place to be treated as a U.S. person for U.S. federal income tax purposes, or (4) an estate that is subject toU.S. federal income tax regardless of its source.

Further, this discussion is for general information only and does not purport to consider all aspects of U.S. federal income taxation that might be relevant to U.S. holders in light of their particular circumstances and does not apply to U.S. holders subject to special treatment under the U.S. federal income tax laws, including, without limitation, dealers or brokers in securities, commodities or currencies, traders in securities that elect to apply a mark-to-market method of accounting, banks and certain other financial institutions, insurance companies, mutual funds, tax-exempt organizations and entities, including pension plans, individual retirement accounts and employee stock ownership plans, holders subject to the alternative minimum tax provisions of the Code, partnerships, S corporations or other pass-through entities or investors in such entities, regulated investment companies, real estate investment trusts, former citizens or residents of the United States, holders whose functional currency is not the U.S. dollar, or holders who hold shares of HSBI stock as part of a hedge, straddle, constructive sale, conversion transaction or other integrated investment. In addition, 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).

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

Determining the actual tax consequences of the merger to you may be complex and will depend on your specific situation. You should consult with your own tax advisor as to the specific tax consequences of the merger in your particular circumstances, including the applicability and effect of the alternative minimum tax

106

and any state, local, foreign and other tax laws and of possible changes in those laws after the date of this joint proxy statement/prospectus.

Tax Consequences of the Merger Generally

The parties intend for the merger to qualify as a “reorganization” within the meaning of Section 368(a) of the Code. In connection with the filing with the SEC of the registration statement of which this joint proxy statement/prospectus is a part, Nelson Mullins Riley & Scarborough LLP, counsel to HSBI, has rendered its tax opinion to HSBI and Alston & Bird LLP, counsel to First Bancshares, has rendered its tax opinion to First Bancshares, in each case to the effect that, as of the date of such opinions and subject to the qualifications and assumptions therein, the merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code. Copies of such tax opinions are attached as Exhibits 8.1 and 8.2 to the registration statement.

The obligations of the parties to complete the merger are conditioned on, among other things, the receipt by First Bancshares and HSBI of opinions from Alston & Bird LLP and Nelson Mullins Riley & Scarborough LLP, respectively, dated the closing date of the merger, to the effect that the merger will be treated as a “reorganization” within the meaning of Section 368(a) of the Code. The opinions of Alston & Bird LLP and Nelson Mullins Riley & Scarborough LLP provided to First Bancshares and HSBI, 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 joint proxy statement/prospectus forms a part. In rendering their opinions, Alston & Bird LLP and Nelson Mullins Riley & Scarborough LLP will rely upon representations and covenants of First Bancshares and HSBI, including those representations contained in certificates of officers of First Bancshares and HSBI, 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 the IRS or a court considering the issues described herein. In addition, neither HSBI 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 following discussion assumes that the merger qualifies as a “reorganization” within the meaning of Section 368(a) of the Code.

U.S. Holders that Exchange HSBI Stock Solely 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 HSBI stock solely for shares of First Bancshares common stock:

•

would generally not recognize any gain or loss upon the exchange of shares of HSBI stock for shares of First Bancshares common stock in the merger;

•

would generally have an aggregate tax basis in the First Bancshares common stock received in the merger (including fractional shares of First Bancshares common stock deemed received and exchanged for cash, as described below) equal to its aggregate tax basis in the HSBI stock surrendered in exchange therefor; and

•

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

If you acquired different blocks of HSBI stock at different times or at different prices, the adjusted tax basis and holding period of each block of First Bancshares common stock you receive would be determined on a block-for-block basis depending on the adjusted tax basis and holding period of the blocks of HSBI

107

TABLE OF CONTENTS

stock surrendered in exchange therefor. Holders should consult their tax advisors regarding the manner in which shares of First Bancshares common stock should be allocated among different blocks of their HSBI stock surrendered in the merger.

Exercise of Dissenters’ Rights

As part of the exercise of dissenters’ rights, a U.S. holder will exchange all of its HSBI stock for cash. A U.S. holder that receives only cash in exchange for its HSBI stock will generally recognize gain or loss equal to the difference between the amount of cash received and such U.S. holder’s adjusted tax basis in its HSBI 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’s holding period for its shares of HSBI stock exceeds one year. Long-term capital gain of non-corporate taxpayers, including individuals, is generally taxed at preferential rates. 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 U.S. holders of HSBI stock unless the holder:

•

furnishes a correct taxpayer identification number, certifies that it is not subject to backup withholding on Form W-9 (or a 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 HSBI stock surrendered by such U.S. holder, and (b) to retain permanent records of these facts relating to the merger. A “significant holder” is any HSBI shareholder that, immediately before the merger, (y) owned at least 1% (by vote or value) of the outstanding stock of HSBI or (z) owned HSBI securities with a basis for U.S. federal income tax purposes of at least $1.0 million.

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. This discussion is for general information purposes only and is not tax advice. Holders of HSBI stock are urged to consult their 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 any tax consequences arising under any other U.S. federal tax laws, or under the laws of any state, local, foreign or other taxing jurisdiction or under any applicable tax treaty. Holders of HSBI stock are also urged to consult their tax advisors with respect to the effect of possible changes in any of those laws after the date of this joint proxy statement/prospectus.

Accounting Treatment

The merger will be accounted for under the acquisition method of accounting for business combinations under GAAP. Under this method, HSBI’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 HSBI 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

108

TABLE OF CONTENTS

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 HSBI beginning on the date of completion of the merger.

Dissenters’ Rights for HSBI Shareholders

Under the terms of the merger agreement, holders of HSBI common stock will be entitled to dissent from the merger and to obtain payment in cash of the fair value of their shares of HSBI common stock. Set forth below is a summary of the procedures that must be followed by the holders of HSBI common stock in order to exercise their dissenters’ rights of appraisal. This summary is qualified in its entirety by reference to the text of the applicable Georgia statutes, a copy of which is attached to this proxy statement as Annex C.

Any holder of record of HSBI common stock who objects to the merger, and who fully complies with all of the provisions of Article 13 of the GBCC (but not otherwise), will be entitled to demand and receive payment for all of his or her shares of HSBI common stock if the merger is consummated.

A shareholder of HSBI who objects to the merger and desires to receive payment of the “fair value” of his or her HSBI common stock: (i) must deliver to HSBI, prior to the time the shareholder vote on the HSBI merger proposal is taken, a written notice of such shareholder’s intent to demand payment for those shares registered in the dissenting shareholder’s name if the merger is completed; and (ii) must not vote his or her shares in favor of the approval of the HSBI merger proposal.

A failure to vote against the HSBI merger proposal will not constitute a waiver of dissenters’ rights. A vote against the approval of the HSBI merger proposal alone will not constitute the separate written notice and demand for payment referred to immediately above. Dissenting shareholders must separately comply with the above conditions.

Any notice required to be given to HSBI must be sent to HSBI’s chief executive office at 125 Westridge Industrial Blvd., McDonough, Georgia 30253 Attn: Phil Resch, Chief Financial Officer. References to HSBI following the completion of the merger as described in this — Dissenters’ Rights for HSBI Shareholders section shall refer to First Bancshares as the surviving corporation in merger.

If the HSBI merger proposal is approved and the merger is completed, HSBI will mail, no later than 10 days after the effective date of the merger, by certified mail to each shareholder who has timely submitted a written notice of intent to dissent in accordance with Article 13 of the GBCC, written notice addressed to the shareholder at such address as the shareholder has furnished HSBI in writing or, if none, at the shareholder’s address as it appears on the records of HSBI. This notice, known as the dissenters’ notice will: (i) state where the dissenting shareholder must send a payment demand, and where and when the certificates for the dissenting shareholder’s shares, if any, are to be deposited; (ii) inform holders of uncertificated shares to what extent transfer of the shares will be restricted after the payment demand is received; (iii) set a date by which HSBI must receive the shareholder’s payment demand (which date may not be fewer than 30 nor more than 60 days after the date the dissenters’ notice is delivered); and (iv) be accompanied by a copy of Article 13 of the GBCC.

Within 10 days after the later of the effective date of the merger, or the date on which HSBI receives a payment demand, HSBI will send a written offer to each shareholder who complied with the provisions set forth in the dissenters’ notice to pay each such shareholder an amount that HSBI estimates to be the fair value of those shares, plus accrued interest. The offer of payment will be accompanied by: (i) HSBI’s balance sheet as of the end of a fiscal year ending not more than 16 months before the offer of payment, an income statement for that year, a statement of changes in shareholders’ equity for that year, and the latest available interim financial statements, if any; (ii) a statement of HSBI’s estimate of the fair value of the shares; (iii) an explanation of how any interest was calculated; (iv) a statement of the dissenting shareholder’s right to demand payment of a different amount under Section 14-2-1327 of the GBCC; and (v) a copy of Article 13 of the GBCC.

A dissenting shareholder choosing to accept HSBI’s offer of payment must do so by written notice to HSBI within 30 days after receipt of HSBI’s offer of payment. A dissenting shareholder not responding to that offer within the 30 day period will be deemed to have accepted the offer of payment. HSBI must make

109

TABLE OF CONTENTS

payment to each shareholder who accepts HSBI’s offer of payment (by written notice to HSBI within 30 days after receipt of HSBI’s offer) or is deemed to have accepted HSBI’s offer of payment (by failure to respond within said 30 days) within 60 days after the making of the offer of payment, or the effective date of the merger, whichever is later. Upon payment, the dissenting shareholder will cease to have any interest in his or her shares of HSBI common stock.

If a dissenting shareholder believes the amount offered by HSBI under HSBI’s written offer of payment is less than the fair value of his shares or that the interest due is incorrectly calculated, the dissenting shareholder may notify HSBI in writing of his or her own estimate of the fair value of his or her shares and amount of interest due, and demand payment of his or her estimate of the fair value of his or her shares and interest due. The dissenting shareholder waives his or her right to demand payment and is deemed to have accepted HSBI’s offer unless he or she notifies the corporation in writing, within 30 days after HSBI’s offer, of his or her demand of some other estimate of the fair value of the shares and interest due thereon.

If a dissenting shareholder does not accept, within 30 days after HSBI’s offer, the estimate of fair value in payment for such shares and interest due thereon and demands payment of some other estimate of the fair value of the shares and interest due thereon, then HSBI, within 60 days after receiving the payment demand of a different amount from a dissenting shareholder, must commence a proceeding in superior court of the county where its registered office is located to determine the rights of the dissenting shareholder and the fair value of his or her shares and accrued interest. If HSBI does not commence the proceedings within the 60 day period, then it must pay each dissenter whose demand remains unsettled the amount demanded by the dissenting shareholder.

In the event of a court proceeding, the court will determine all costs of the proceeding, including the reasonable compensation and expenses of appraisers appointed by the court, but not including fees and expenses of attorneys and experts for the respective parties. The court will assess these costs against HSBI, except that the court may assess these costs against all or some of the dissenters in amounts the court finds equitable to the extent the court finds the dissenters acted arbitrarily, vexatiously or not in good faith in demanding payment under the dissenters’ provisions. The court may also assess the fees and expenses of attorneys and experts for the respective parties in amounts the court finds equitable: (i) against HSBI and in favor of any or all dissenters if the court finds HSBI did not substantially comply with the dissenters’ provisions; or (ii) against HSBI or a dissenter in favor of any other party if the court finds that the party against whom fees and expenses are assessed acted arbitrarily or not in good faith with respect to the rights provided by the dissenters’ provisions. If the court finds that the services of attorneys for any dissenter were of substantial benefit to other dissenters similarly situated and that the fees for those services should not be assessed against HSBI, the court may award these attorneys reasonable fees to be paid out of the amounts awarded the dissenters who were benefited.

HSBI shareholders should be aware that cash paid to dissenting shareholders in satisfaction of the fair value of their shares of HSBI common stock will result in the recognition of any gain or loss realized for U.S. federal income tax purposes.

Failure by a HSBI shareholder to follow the steps required by the GBCC for perfecting dissenters’ rights may result in the loss of such rights. In view of the complexity of these provisions and the requirement that they be strictly complied with, if you hold HSBI common stock and are considering dissenting from the approval of the merger exercising your dissenters’ rights under the GBCC, you should consult your legal advisors.

BECAUSE OF THE COMPLEXITY OF THE PROVISIONS OF GEORGIA LAW RELATING TO DISSENTERS’ APPRAISAL RIGHTS, SHAREHOLDERS WHO ARE CONSIDERING DISSENTING FROM THE MERGER ARE URGED TO CONSULT THEIR OWN LEGAL ADVISORS.

Exchange of Shares in the Merger

The conversion of HSBI 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 HSBI common stock for the merger consideration to be received pursuant

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 joint proxy statement/prospectus as Annex A and is incorporated by reference into this joint 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 HSBI have each unanimously approved the merger agreement, which provides for the merger of HSBI 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, Heritage Southeast Bank, which is a Georgia state-chartered bank and a direct wholly owned subsidiary of HSBI, 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 Heritage Southeast 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 Heritage Southeast 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 Heritage Southeast 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 HSBI 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 U.S. federal income tax treatment of HSBI shareholders in connection with the merger, or (iv) require submission to or the approval of HSBI shareholders after the HSBI merger proposal has already been approved by HSBI’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, (ii) the date and time when the merger becomes effective as set forth in such articles of merger, which shall be within thirty 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 fourth quarter of 2022 or first quarter of 2023, subject to obtaining the requisite approvals from the shareholders of HSBI, 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 HSBI 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.

112

TABLE OF CONTENTS

Board Composition and Management of Surviving Company

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 the First Bancshares Bylaws. First Bancshares has also agreed to evaluate and consider the current directorate of HSBI in good faith, and, upon completion of such evaluation, consider expanding the board of directors of First Bancshares by one position and appointing one current member of the board of directors of HSBI to serve as a director of First Bancshares following the merger.

Merger Consideration

Under the terms of the merger agreement, each share of HSBI common stock issued and outstanding immediately prior to the effective time of the merger will be converted into the right to receive 0.965, or the exchange ratio, shares of First Bancshares common stock. To the extent that any shares of HSBI stock are subject to vesting restrictions, such shares will fully vest upon the closing of the merger and will also be converted into receive 0.965, or the exchange ratio, shares of First Bancshares common stock.

If First Bancshares or HSBI change the number of shares of First Bancshares common stock or HSBI 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 HSBI 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 HSBI shareholders the same economic effect as contemplated by the merger agreement prior to any such event.

All restricted stock awarded under the HSBI equity plans will fully vest at the closing of the merger and be converted automatically into a number of shares of First Bancshares common stock equal to the product (with the result rounded down to the nearest whole share) of (i) the number of restricted shares of HSBI common stock subject to such award multiplied by (ii) 0.965, with any fractional share being paid in cash in lieu thereof.

All stock options awarded under the HSBI equity plans will, automatically and without any action on the part of the holder of the stock option, be converted into the right to receive an amount of cash equal to the product of (A) the excess, if any, of (1) the product of (x) 0.965, multiplied by (y) $29.68, over (2) the per share exercise price of the HSBI stock option prior to the effective time of the merger, multiplied by (B) the number of shares of HSBI common stock subject to such HSBI stock option prior to the effective time (rounded up to the nearest whole cent).

The value of the shares of First Bancshares common stock to be issued to HSBI 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.

TABLE OF CONTENTS

Procedures for Converting Shares of HSBI 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 HSBI shareholders for the purpose of receiving their HSBI 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 five 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 HSBI common stock (other than excluded shares) providing instructions on how to effect the delivery of certificates or book-entry shares of HSBI stock in exchange for the merger consideration. After the effective time of the merger, when a HSBI 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 HSBI 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 HSBI Stock Certificates

The exchange agent will mail to each holder of record of HSBI 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 HSBI stock held by the shareholder.

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 HSBI stock, accompanied by a properly completed letter of transmittal, a HSBI 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 HSBI stock certificates or book-entry shares with respect to the shares of HSBI 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 HSBI 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.

114

TABLE OF CONTENTS

None of First Bancshares, the exchange agent or any other person will be liable to any former HSBI 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 HSBI 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 HSBI 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 HSBI other than to settle transfers of HSBI 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 HSBI stock. The shares of First Bancshares common stock issued in accordance with the merger agreement upon conversion of the shares of HSBI 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 HSBI 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.

Definition of “Material Adverse Effect”

Certain representations and warranties of First Bancshares and HSBI 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 HSBI, 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

116

TABLE OF CONTENTS

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. For purposes of clause (i) only, the definition of “material adverse effect” excludes the following:

•

changes in banking and similar laws of general applicability or interpretations thereof by any governmental authority;

•

changes in GAAP or regulatory accounting requirements applicable to banks or bank holding companies generally;

•

changes in global, national or regional political conditions (including the outbreak of war or acts of terrorism) or in economic or market (including equity, credit and debt markets, as well as changes in interest rates) conditions affecting the financial services industry generally;

•

public disclosure of the transactions contemplated or actions expressly required by the merger agreement or actions or omissions that are taken with the prior written consent of the other party, or as otherwise expressly permitted or contemplated by the merger agreement;

•

any failure by HSBI or First Bancshares to meet any internal or published industry analyst projections or forecasts or estimates of revenues or earnings for any period (it being understood and agreed that the facts and circumstances giving rise to such failure that are not otherwise excluded from the definition of material adverse effect may be taken into account in determining whether there has been a material adverse effect);

•

changes in the trading price or trading volume of First Bancshares common stock or HSBI common stock (it being understood and agreed that the facts and circumstances giving rise to such change in trading price or trading volume that are not otherwise excluded from the definition of material adverse effect may be taken into account in determining whether there has been a material adverse effect);

•

the impact of this merger agreement and the transactions contemplated by the merger agreement on relationships with customers or employees, including the loss of personnel; and

•

the impact of the “day one accounting” adjustments required to be made by HSBI pursuant to FASB ASC Topic 805 “Business Combinations”;

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.

First Bancshares and HSBI 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 HSBI 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 HSBI) on the condition (financial or otherwise), results of operations, liquidity, assets or deposit liabilities, properties or business of First Bancshares, HSBI, the surviving entity or the surviving bank, after giving effect to the merger (a “burdensome condition”).

121

TABLE OF CONTENTS

First Bancshares and HSBI 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 HSBI 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 HSBI 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 HSBI 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 HSBI 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 HSBI 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 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 HSBI (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 HSBI and the employees’ weekly rate of pay.

Prior to the effective time of the merger, HSBI will effectuate the termination or discontinuation of certain benefits plans maintained by HSBI, 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 HSBI and its subsidiaries against all costs or expenses, judgments, fines, losses, claims, damages or other liabilities

122

TABLE OF CONTENTS

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 HSBI 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 HSBI 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 HSBI 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 HSBI; 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 HSBI 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 250% of the annual premiums paid by HSBI 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

HSBI 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 HSBI 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 HSBI 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 HSBI 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 HSBI 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 HSBI or any of its subsidiaries, constituting, in the aggregate, 20% or more of the fair value of the consolidated assets of HSBI; (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 HSBI 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 HSBI 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 HSBI special meeting, HSBI may take any of the actions described in the first paragraph of this “— No Solicitation” section if, but only if (i) HSBI receives a bona fide unsolicited

123

TABLE OF CONTENTS

acquisition proposal that did not result from a breach of the first paragraph of this section, and (ii) the HSBI 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) HSBI has provided First Bancshares with at least three business days prior notice of such determination, and (iv) prior to furnishing or affording access to any information or data with respect to HSBI or any of its subsidiaries or otherwise relating to an acquisition proposal, HSBI receives from such person a confidentiality agreement with terms no less favorable to HSBI than those contained in the confidentiality agreement with First Bancshares. HSBI must promptly provide to First Bancshares any non-public information regarding HSBI 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 HSBI or any of its subsidiaries, the shareholders of such third party) acquiring, directly or indirectly, more than 50% of the outstanding HSBI stock or more than 50% of the assets of HSBI and its subsidiaries (measured as a percentage of the fair value of the consolidated assets of HSBI), taken as a whole, for consideration consisting of cash and/or securities and (ii) that the board of directors of HSBI 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 HSBI from a financial point of view than the merger.

HSBI must promptly (and in any event within 48 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, HSBI 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 making such offer or proposal under an effective confidentiality agreement). HSBI 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 HSBI 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 HSBI 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 HSBI 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 HSBI recommendation within three business days following a request by First Bancshares, or make any statement, filing or release, in connection with the HSBI meeting or otherwise, inconsistent with the HSBI recommendation; or (vi) resolve to do any of the foregoing.

Notwithstanding the foregoing, prior to the receipt of the requisite HSBI shareholder approval, the board of directors of HSBI may withdraw, qualify, amend or modify the HSBI recommendation (“HSBI subsequent determination”) or cause or permit HSBI to terminate the merger agreement to enter into a

TABLE OF CONTENTS

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 HSBI advising First Bancshares that the board of directors of HSBI 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 HSBI 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 HSBI’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”), HSBI and the board of directors of HSBI 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 HSBI to proceed with the HSBI recommendation in favor of the merger with First Bancshares without a HSBI 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 HSBI 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, HSBI 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.

•

HSBI terminates the merger agreement after following the requisite procedures in the merger agreement for the purpose of entering into an acquisition agreement with respect to a superior proposal in compliance with the terms of the merger agreement.

Effect of Termination

A termination of the merger agreement will not relieve a breaching party from liability for any breach of any covenant, agreement, representation or warranty of the merger agreement giving rise to such termination or resulting from fraud or any willful and material breach. Notwithstanding the foregoing, the parties have agreed that if HSBI pays or causes to be paid to First Bancshares the termination fee in accordance with the merger agreement, HSBI (or any successor in interest of HSBI) will not have any further obligations or liabilities to First Bancshares with respect to the merger agreement or the transactions contemplated by it.

Amendment; Waiver

Prior to the effective time of the merger and to the extent permitted by applicable law, any provision of the merger agreement may be (a) waived by the party benefitted by the provision, provided the waiver is in writing and signed by such party, or (b) amended or modified at any time, by an agreement in writing between the parties, except that after the HSBI special meeting no amendment may be made which by law requires further approval by the shareholders of First Bancshares or HSBI without obtaining such approval.

Expenses

All expenses incurred in connection with the merger, the bank merger, the merger agreement and other transactions contemplated thereby, including fees and expenses of financial consultants, accountants and counsel, will be paid by the party incurring the expenses. Nothing in the merger agreement limits either party’s rights to recover any liabilities or damages arising out of the other party’s willful breach of any provision of the merger agreement.

Legal Proceedings

Heritage Southeast Bank is periodically a party to or otherwise involved in legal proceedings arising in the normal course of business, such as claims to enforce liens, claims involving the making and servicing of real property loans, and other issues incident to its business. Management does not believe that there is any pending or threatened proceeding against Heritage Southeast Bank which, if determined adversely, would have a material adverse effect on Heritage Southeast Bank’s financial position, liquidity, or results of operations.

Competition

Heritage Southeast Bank encounters strong competition both in making loans and in attracting deposits. The deregulation of the banking industry and the widespread enactment of state laws which permit multi-bank holding companies as well as an increasing level of interstate banking have created a highly competitive environment for commercial banking. In one or more aspects of its business, Heritage Southeast Bank competes with other commercial banks, savings and loan associations, credit unions, finance companies, mutual funds, insurance companies, brokerage and investment banking companies, and other financial intermediaries. Most of these competitors, some of which are affiliated with bank holding companies, have substantially greater resources and lending limits, and may offer certain services that Heritage Southeast Bank does not currently provide. In addition, many of Heritage Southeast Bank’s non-bank competitors are not subject to the same extensive federal regulations that govern bank holding companies and federally insured banks. Recent federal and state legislation has heightened the competitive environment in which financial institutions must conduct their business, and the potential for competition among financial institutions of all types has increased significantly. There is no assurance that increased competition from other financial institutions will not have an adverse effect on Heritage Southeast Bank’s operations.

In this section, unless the context suggests otherwise, references to “we,” “us,” and “our” mean the combined business of Heritage Southeast Bancorporation Inc. (“Heritage”) and its wholly-owned subsidiary, Heritage Southeast Bank.

The following discussion and analysis of Heritage’s consolidated financial condition at June 30, 2022, compared to December 31, 2021, and results of operations for the three and six months ended June 30, 2022 and 2021 and the years ended December 31, 2021 and 2020 should be read in conjunction with our consolidated financial statements and related notes thereto included elsewhere in this joint proxy statement/prospectus. Historical results of operations and the percentage relationships among any amounts included, and any trends that may appear, may not indicate trends in operations or results of operations for any future periods.

Comments regarding our business that are not historical facts are considered forward-looking statements that involve inherent risks and uncertainties. Actual results may differ materially from those contained in these forward-looking statements. For additional information regarding our cautionary disclosures, see the “Cautionary Note Regarding Forward-Looking Statements” beginning on page 21 of this joint proxy statement/prospectus.

Overview

Heritage Southeast Bancorporation, Inc., headquartered in Jonesboro, Georgia, is the bank holding company for Heritage Southeast Bank, a Georgia state-chartered bank, which operates as Heritage Bank, Providence Bank, and The Heritage Bank.

We offer a range of lending services, including consumer, real estate and commercial loans to individuals and small businesses and other organizations that are located in or conduct a substantial portion of their business in our market areas, with a branch network in metro Atlanta, southeast Georgia, and Jacksonville, Florida. Our product line includes residential mortgage loans, commercial loans and commercial real estate loans and a variety of commercial and consumer deposit products, including non-interest bearing accounts, interest-bearing demand products, savings accounts, money market accounts and certificates of deposit. We also offer online banking and bill payment services, online cash management, safe deposit box rentals, debit card and ATM card services and the availability of a network of ATMs for our customers.

COVID-19 Pandemic

Our historically careful underwriting practices and diverse loan portfolio has helped minimize the adverse impact of the COVID-19 pandemic on Heritage. In addition, the combination of the vaccine rollout, government stimulus payments, and reduced spending during the pandemic are likely contributing factors mitigating the impact of the pandemic on our business, financial condition, results of operations, and our customers as of June 30, 2022. While vaccine availability and uptake has increased, the longer term macro-economic effects on global supply chains, inflation, labor shortages and wage increases continue to impact many industries. The ultimate extent of the impact of the COVID-19 pandemic on our business, financial condition and results of operations is currently uncertain and will depend on various developments and other factors, including new COVID-19 cases, hospitalizations and deaths leading to additional government imposed restrictions; refusals to receive the vaccine along with concerns related to new strains of the virus; supply chain issues remaining unresolved longer than anticipated; labor shortages and wage increases continuing to impact many industries; consumer confidence and spending falls; and rising geopolitical tensions. Given the ongoing and dynamic nature of the circumstances surrounding the pandemic, it is difficult to predict its future adverse financial impact on us, although we expect to continue to be impacted by the pandemic throughout the remainder of 2022.

Critical Accounting Estimates

Our consolidated financial statements are prepared based on the application of accounting policies in accordance with generally accepted accounting principles (“GAAP”) and follow general practices within the

134

TABLE OF CONTENTS

banking industry. These policies require the reliance on estimates, assumptions and judgements, which may prove inaccurate or are subject to variations. Changes in underlying factors, estimates, assumptions or judgements could have a material impact on our future financial condition and results of operations.

Certain policies inherently have a greater reliance on the use of estimates, assumptions and judgments and, as such, have a greater possibility of producing results that could be materially different than originally reported. We have identified the determination of the allowance for loan losses, valuation of deferred tax assets and the fair value of purchase accounting adjustments to be the accounting areas that require the most subjective or complex judgments and, as such, could be most subject to revision as new or additional information becomes available or circumstances change, including overall changes in the economic climate and/or market interest rates. Therefore, we consider these policies, discussed below, to be critical accounting estimates and discuss them directly with the Audit Committee of our board of directors.

Our significant accounting policies are presented in Note 1 of our audited consolidated financial statements included in this joint proxy statement/prospectus. These policies, along with the disclosures presented in the other financial statement notes and in this discussion, provide information on how significant assets and liabilities are valued in the financial statements and how those values are determined. Recent accounting pronouncements and standards that have impacted or could potentially affect us are also discussed in Note 1 of our audited consolidated financial statements.

Allowance for loan losses

We maintain the allowance for loan losses, or allowance, at a level we believe is sufficient to absorb probable incurred losses in our loan portfolio given the conditions at the time. Determining the allowance is considered a critical accounting estimate because it requires significant judgment and the use of estimates related to the amount and timing of expected future cash flows on impaired loans, estimated losses based on risk characteristics of loans and consideration of other qualitative factors, all of which may be susceptible to significant change. In addition, events that are not within our control, such as changes in economic factors, could change subsequent to the reporting date and could cause the allowance to be overstated or understated. The amount of the allowance is affected by loan charge-offs, which decrease the allowance; recoveries on loans previously charged off, which increase the allowance; and the provision for loan losses charged to earnings, which increases the allowance. In determining the provision for loan losses, management monitors fluctuations in the allowance for loan losses resulting from actual charge-offs and recoveries and reviews the size and composition of the loan portfolio in light of current and anticipated economic conditions.

Income Taxes

The assessment of income tax assets and liabilities involves the use of estimates, assumptions, interpretation, and judgment concerning certain accounting pronouncements and federal and state tax codes. There can be no assurance that future events, such as court decisions or positions of federal and state taxing authorities, will not differ from management’s current assessment, the impact of which could be significant to the results of operations and reported earnings.

We file federal and a state income tax returns. Amounts provided for income tax expense are based on income reported for financial statement purposes and do not necessarily represent amounts currently payable under tax laws. Deferred income tax assets and liabilities are computed for differences between the financial statement and tax bases of assets and liabilities that will result in taxable or deductible amounts in the future based on enacted tax law rates applicable to the periods in which the differences are expected to affect taxable income. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income tax expense. Valuation allowances are established when it is more likely than not that a portion of the full amount of the deferred tax asset will not be realized. In assessing the ability to realize deferred tax assets, management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies. We may also recognize a liability for unrecognized tax benefits from uncertain tax positions. Unrecognized tax benefits represent the differences between a tax position taken or expected to be taken in a tax return and the benefit recognized and measured in the financial statements. Penalties related to unrecognized tax benefits are classified as income tax expense.

135

TABLE OF CONTENTS

Business Combinations

We account for transactions that meet the definition of a purchase business combination by recording the assets acquired and liabilities assumed at their fair value upon acquisition. Intangible assets, indemnification contracts and contingent consideration are identified and recognized individually. If the fair value of the assets acquired exceeds the purchase price plus the fair value of the liabilities assumed, a bargain purchase gain is recognized. Conversely, if the purchase price plus the fair value of the liabilities assumed exceeds the fair value of the assets acquired, goodwill is recognized.

Accounting for Acquired Loans

We record purchased loans at fair value at the date of acquisition based on a discounted cash flow methodology that considers various factors, including the type of loan and related collateral, classification status, whether the loan has a fixed or variable interest rate, its term and whether or not the loan was amortizing, and our assessment of risk inherent in the cash flow estimates. These cash flow evaluations are inherently subjective as they require material estimates, all of which may be susceptible to significant change. Purchased loans are segregated into two categories upon purchase: (1) loans purchased without evidence of deteriorated credit quality since origination, referred to as purchased non-credit impaired (“non-PCI”) loans, and (2) loans purchased with evidence of deteriorated credit quality since origination for which it is probable that all contractually required payments will not be collected, referred to as purchased credit impaired (“PCI”) loans.

Loans acquired in a business combination, with respect to which there is evidence of credit deterioration since origination and it is probable at the date of acquisition that we will not collect all contractually required principal and interest payments, are accounted for under accounting guidance for PCI loans. For each acquisition, we have aggregated the PCI loans into pools of loans with common risk characteristics. Over the life of these acquired loans, we continue to estimate cash flows expected to be collected on individual loans or on pools of loans sharing common risk characteristics. For each pool of loans, we estimate cash flows expected to be collected over the remaining life of the pool’s loans, based on assumptions about yields, prepayments and magnitude and timing of credit losses, and discount those cash flows to present value using effective interest rates to calculate the carrying value. The difference between our carrying value in the loans and our estimates of cumulative lifetime undiscounted expected cash flows represents the accretable yield. The accretable yield represents the amount we expect to recognize as interest income over the remaining life of the loans. The difference between the cash flows that our customers legally owe us under the contractual terms of their loan agreements and our cumulative lifetime expected cash flows represents the nonaccretable difference. The nonaccretable difference of a pool is a measure of the expected credit loss, prepayments and other factors affecting expected cash flows for that pool.

Each quarter, we estimate the expected cash flows for each pool or specifically reviewed loan and evaluate whether the present value of future expected cash flows for each pool or loan has decreased below its carrying value and, if so, we recognize a provision for credit loss in our consolidated statement of operations for that pool or loan and appropriately adjust the amount of accretable yield. The expected cash flows are estimated based on factors which include loan grades established in our ongoing credit review program, past due status, likelihood of default based on observations of specific loans during the credit review process as well as applicable industry data, loss severity based on updated evaluation of cash flow from available collateral, and the contractual terms of the underlying loan agreement. For any pool or loan where the present value of our most recent estimate of future cumulative lifetime cash flows has increased above its recorded investment, we transfer appropriate estimated cash flows from non-accretable difference to accretable yield, which is then recognized in income first in the reversal of any impairment, then on a prospective basis through an increase in the pool’s or individual loan yield over its remaining life.

Results of Operations

General

Our results of operations depend substantially on net interest income, which is the difference between interest income on interest-earning assets, consisting primarily of interest income on loans, investment securities and other short-term investments, as well as accretion income on purchased loans, and interest

expense on interest-bearing liabilities, consisting primarily of deposits and borrowings. Our results of operations are also dependent on our generation of non-interest income, consisting primarily of income from service charges on deposit accounts, interchange and ATM fees, wealth management advisory fees, gains on sales of SBA loans and mortgage banking activities. Other factors contributing to our results of operations include our provisions for loan losses, income taxes, and non-interest expenses, such as salaries and employee benefits, occupancy, amortization of intangible assets and other operating costs.

We had net income of $3.3 million for the second quarter of 2022, compared to $2.9 million for the second quarter of 2021. The $460,000 increase in net income for the second quarter of 2022, compared to the same period in 2021, was primarily due to higher net interest income. We had net income of $7.2 million for both the six months June 30, 2022 and 2021.

We had net income of $13.8 million for the year ended December 31, 2021, compared to $4.4 million for the year ended December 31, 2020. The $9.4 million increase in net income for the year ended December 31, 2021, compared to the year ended 2020, was primarily due to a $9.4 million reduction in our provision for loan losses in 2021. Our provision for credit losses in 2020 considered the forecasted impact of COVID-19 and related uncertainty. The decrease in provision expense for 2021 reflected improved economic conditions in 2021 and the projected impact of the COVID-19 pandemic on our future loan losses was anticipated to be less than our prior projections.

Net Interest Income

Net interest income, representing interest income less interest expense, is a significant contributor to our revenues and earnings. We generate interest income from interest and dividends on interest-earning assets, including loans and investment securities we own. We incur interest expense from interest paid on interest-bearing liabilities, including interest-bearing deposits and other borrowings. To evaluate net interest income, we measure and monitor (a) yields on our loans and other interest-earning assets, (b) the costs of our deposits and other funding sources, (c) our net interest spread and (d) our net interest margin. Net interest spread is the difference between rates earned on interest-earning assets and rates paid on interest-bearing liabilities. Net interest margin is calculated as the annualized net interest income divided by average interest-earning assets. Because non-interest-bearing sources of funds, such as non-interest-bearing deposits and stockholders’ equity, also fund interest-earning assets, net interest margin includes the benefit of these non-interest-bearing sources.

Interest earned on our loan portfolio is the largest component of our interest income. Our originated and purchased non-credit impaired loan (“non-PCI”) portfolios are presented at the principal amount outstanding net of deferred origination fees and unamortized discounts and premiums. Interest income is recognized based on the principal balance outstanding and the stated rate of the loan. Loan origination fees and certain direct origination costs are capitalized and recognized as an adjustment of the yield on the related loan. Non-PCI loans acquired through our acquisitions were initially recorded at fair value. Discounts or premiums created when the loans were recorded at their estimated fair values at acquisition are being accreted over the remaining term of the loan as an adjustment to the related loan’s yield.

The performance of loans within our purchased credit impaired (“PCI”) portfolio impacts interest income as the remaining discounts and proceeds received in excess of expected cash flow are realized in interest income when these loans are closed through payoff, charge off, workout, sale or foreclosure. At acquisition, the expected shortfall in future cash flows on our PCI portfolio, as compared to the contractual amount due, was recognized as a non-accretable discount. Any excess of expected cash flows over the acquisition date fair value is known as the accretable discount, and is recognized as accretion income over the life of each pool or individual PCI loan. Expected cash flows over the acquisition date fair value are re-estimated quarterly utilizing the same cash flow methodology used at the time of acquisition. Any subsequent decreases to the expected cash flows will generally result in a provision for credit losses charge in the consolidated statements of income. Conversely, subsequent increases in expected cash flows result in a transfer from the non-accretable discount to the accretable discount, which has a positive impact on accretion income prospectively.

Our net interest income can be significantly influenced by a variety of factors, including overall loan demand, economic conditions, credit risk, the amount of nonearning assets including nonperforming loans

and OREO, the amounts of and rates at which assets and liabilities reprice, variances in prepayment of loans and securities, early withdrawal of deposits, exercise of call options on borrowings or securities, a general rise or decline in interest rates, changes in the slope of the yield-curve, and balance sheet growth or contraction.

Quarter Ended June 30, 2022 and 2021

Our net interest income was $13.2 million for the second quarter of 2022, an increase of $478,000, from the same period in 2020. This increase was primarily attributable to increases in income on loans, investment securities, deposits with other banks and a decrease in interest expense, partially offset by a $910,000 decrease in PPP loan income.

Average earning assets for the second quarter of 2022 were $1.6 billion, reflecting an increase of $70.2 million, or 4.6%, compared to the second quarter of 2021. Total average loans totaled $1.1 billion in the second quarter of 2022, which reflected an increase of $22.9 million compared to the second quarter of 2021. All loan segments contributed to the growth in average loan balances. For the second quarter of 2022, the yield on average loans decreased to 4.79%, compared to the yield on average loans of 5.10% for the second quarter of 2021. Securities reflected an increase in interest income year over year, due to growth in volume and improved yield on portfolio. Total average securities for the second quarter of 2022 increased $35.5 million from the second quarter of 2021. The yield on average securities improved to 1.28% for the second quarter of 2022 up from 0.91% in the second quarter of 2021.

Average interest-bearing liabilities increased $13.6 million, or 1.3% in the second quarter of 2022 from the second quarter of 2021. In addition, we experienced growth in average noninterest bearing deposits of $39.5 million, compared to the second quarter of 2021, as reductions in market interest rates over the past year have provided less incentive to maintain funds in interest bearing deposits.

Our net interest margin was 3.34% for the second quarter of 2022, compared to 3.37% for the second quarter of 2021, a decrease of 3 basis points. Loan yields were down 31 basis points which was partially offset by improved performance in the investment portfolio, higher interest received from deposits in banks, lower cost on interest bearing deposits and a higher level of demand deposits.

Excluding the impact of our PPP lending, the net interest margin was up 5 basis points in the second quarter of 2022 as compared to second quarter of 2021 (3.31% versus 3.26%).

The following table sets forth information related to our average balance sheet, average yields on assets, and average costs of liabilities for the periods presented. We derived these yields by dividing income or expense by the average balance of the corresponding assets or liabilities. We derived average balances from the daily balances throughout the periods indicated.

Six Months Ended June 30, 2022 and 2021

Our net interest income was $25.5 million for the six months ended June 30, 2022, an increase of $34,000, from the same period in 2021. This increase was due to higher interest income received on balances held with banks, improved investment securities income and lower interest expense. These favorable variances were partly offset by lower interest on loans (principally PPP).

Average earning assets for the first six months of 2022 were $1.6 billion, reflecting an increase of $81.5 million, or 5.5%, compared to the same six months of 2021. Total average loans totaled $1.1 billion in the first half of 2022, up $7.8 million when compared to the same period of 2021. For the first six months of 2022, the yield on average loans decreased to 4.77%, compared to the yield on average loans of 5.14% for the same period of 2021. Securities reflected an increase in interest income period over period, due to growth in volume and improved yield on the portfolio. Total average securities for the first half of 2022 increased $28.5 million from the same period of 2021. The yield on average securities improved to 1.40% for the first six months of 2022 up from 1.03% in the same period of 2021.

Average interest-bearing liabilities increased $13.6 million, or 1.3% in the first half of 2022 from the same period of 2021. In addition, we experienced growth in average noninterest bearing deposits of $50.3 million, compared to the first six months of 2021.

Our net interest margin was 3.29% for the first half of 2022, compared to 3.47% for the six months ended June 30, 2021, a decrease of 18 basis points. Loan yields were down 37 basis points which was partially offset by improved performance in the investment portfolio, higher interest received on deposits with banks, lower cost on interest bearing deposits and a higher level of demand deposits.

Excluding the impact of our PPP lending, the net interest margin was up 7 basis points in the first half of 2022 as compared to the same period in 2021 (3.26% versus 3.19%).

Years Ended December 31, 2021 and 2020

Our net interest income was $51.3 million for the year ended December 31, 2021, an increase of $3.1 million, from the same period in 2020. The increase was primarily due to earnings on the PPP portfolio and lower interest expense as all other earning asset categories reflected slight declines.

Average earning assets for 2021 were $1.5 billion, reflecting an increase of $186.9 million, or 14.3%, compared to the year ended December 31, 2020. Total average loans totaled $1.1 billion in 2021, up $48.1 million when compared to the same period of 2020. For the year ended December 31, 2021, the yield

140

TABLE OF CONTENTS

on average loans decreased to 5.08%, compared to the yield on average loans of 5.31% for the same period of 2020. Securities reflected a slight increase in interest income year over year as growth in volume was offset by a lower yield on the portfolio. Total average securities for the year 2021 increased $35.2 million from the same period of 2020. The yield on average securities declined to 1.12% for the year ended December 31, 2021, down from 1.30% in the same period of 2020.

Average interest-bearing liabilities increased $80.9 million, or 8.8% for the year ended December 31, 2021 as compared to the same period of 2020. In addition, we experienced growth in average noninterest bearing deposits of $89.6 million when compared to year ended December 31, 2020.

Our net interest margin was 3.43% in 2021, compared to 3.68% for the full year 2020, a decrease of 25 basis points. Declines were noted in loan yields (23 basis points), investment securities yields (18 basis points) and interest received from deposits with banks (20 basis points). These reductions were partially offset by lower cost on interest bearing deposits and a higher level of demand deposits.

Excluding the impact of our PPP lending, the net interest margin was down 42 basis points in 2021 as compared to the same period in 2020 (3.31% versus 3.73%).

Rate-Volume Analysis

The tables below present the effect of volume and rate changes on interest income and expense. Changes in volume are changes in in the average balance multiplied by the previous period’s average rate. Changes in rate are changes in the average rate multiplied by the average balance from the previous period. The net changes attributable to the combined impact of both rate and volume have been allocated proportionately to the changes due to volume and the changes due to rate.

Provision for Loan Losses

We established an allowance for loan losses through a provision for loan losses charged as an expense in our consolidated statements of income. The provision for loan losses is the amount of expense that, based on our judgment, is required to maintain the allowance for loan losses at an adequate level to absorb probable losses inherent in the loan portfolio at the balance sheet date and that, in management’s judgment, is appropriate under GAAP. Our determination of the amount of the allowance for loan losses and corresponding provision for loan losses considers ongoing evaluations of the credit quality and level of credit risk inherent in our loan portfolio, levels of nonperforming loans and charge-offs, statistical trends and economic and other relevant factors. The allowance for loan losses is increased by the provision for loan losses and is decreased by charge-offs, net of recoveries on prior loan charge-offs.

We did not record an allowance for loan losses at acquisition for acquired loans as these loans were recorded at fair value, based on a discounted cash flow methodology, upon acquisition. We re-estimate

expected cash flows on a quarterly basis for all PCI loans. We record a provision for loan losses during the period for any decline in expected cash flows on such loans. Conversely, any improvement in expected cash flows is recognized prospectively as an adjustment to the yield on the loan once any previously recorded impairment is recaptured.

We did not record any provision expense for the three and six months ended June 30, 2022 and 2021.

We did not record any provision expense for the year-ended 2021, compared to $9.4 million of provision expense for the year-ended 2020. The decrease in the year over year was primarily due to improved asset quality and continued clarity on the economic and pandemic climate.

Noninterest Revenue

The following table presents our noninterest revenue for the three and six months ended June 30, 2022 and 2021 and the years ended December 31, 2021 and 2020.

Total noninterest income		$	4,325		$	4,607		$	8,452		$	9,103		$	18,969		$	17,618

Our noninterest revenue decreased $282,000 to $4.3 million in the second quarter of 2022, from $4.6 million for the like period in 2021, primarily due to a $308,000 reduction in gain on the sale of SBA loans as the timing of sale closings impacted both periods. This decrease was partially offset by a $191,000 increase in service charges and fees in the second quarter of 2022, compared to the like period in 2021, due to deposit growth and transaction activity.

Our noninterest revenue decreased $651,000 to $8.5 million for the six months ended June 30, 2022, from $9.1 million for the like period in 2021, primarily due to a $794,000 reduction in gain on the sale of SBA loans as market conditions and timing of sale closings impacted both periods. This decrease was partially offset by a $385,000 increase in service charges and fees in the first half of 2022, compared to the like period in 2021, due to deposit growth and transaction volume.

Our noninterest revenue increased $1.4 million for the year ended December 31, 2021 to $19.0 million from $17.6 million for the year 2020. Increases in gain on sale of SBA loans ($2.0 million) and higher interchange and ATM fees ($451,000) being partly offset by reduced securities gains ($1.3 million) accounted for the change. The increase in SBA activity in 2021 was due to additional resources being allocated to the product line.

Total noninterest expense		$	13,182		$	13,491		$	24,925		$	25,336		$	52,448		$	50,919

Our operating expense decreased $309,000 to $13.2 million for the second quarter of 2022, from $13.5 million for the second quarter of 2021, primarily due to a $1.3 million decrease in transaction costs related to the recently terminated VyStar purchase and assumption agreement. This decrease was partially offset by a $1.4 million increase in salary and employee benefits expense, due primarily to employee separation accruals recorded in the second quarter of 2022.

Our operating expense decreased $411,000 to $24.9 million for the six months ended June 30, 2022, from $25.3 million for the same period of 2021. Decreases noted in transaction costs, professional fees, advertising and other real estate owned expenses were partially offset by higher salaries and benefits associated with employee separation accruals recognized in the second quarter in 2022.

Our operating expense increased $1.5 million to $52.4 million for the year ended December 31, 2021, from $50.9 million for the year 2020. Higher VyStar transaction costs of $5.2 million were partly offset by lower salaries and benefits ($1.0 million — headcount), other real estate owned expenses ($904,000), professional fees ($502,000) and advertising costs ($431,000).

Income Taxes

We had income tax expense for the second quarter of 2022 of $1.0 million, compared to $974,000 for the second quarter of 2021. The increase in income tax expense was primarily due to higher pre-tax earnings in the current period. Our effective tax rate was 23.4% and 25.3% for the second quarter of 2022 and 2021, respectively.

We had income tax expense for the six months ended June 30, 2022 of $1.9 million, compared to $2.1 million for the six months ended June 30, 2021. The decrease in income tax expense was primarily due to lower pre-tax income for the six months ended June 30, 2022. Our effective tax rate was 20.8% and 22.2% for the six months ended June 30, 2022 and 2021, respectively.

We had income tax expense for the year-ended 2021 of $4.0 million, compared to $1.1 million for the year-ended 2020. The increase in income tax expense was primarily due to improved earnings in 2021. Our effective tax rate was 22.4% and 19.1% for the year-ended 2021 and 2020, respectively.

Investment Securities

Our securities portfolio is used to make various term investments, maintain a source of liquidity and serve as collateral for certain types of deposits and borrowings. We manage our investment portfolio according to written investment policies approved by our board of directors. Investment in our securities portfolio may change over time based on our funding needs and interest rate risk management objectives. Our liquidity levels take into account anticipated future cash flows and other available sources of funds and are maintained at levels that we believe are appropriate to provide the necessary flexibility to meet our anticipated funding requirements.

Our investment securities portfolio consists of securities classified as available-for-sale. There were no held-to-maturity or trading securities in our investment portfolio as of June 30, 2022, December 31, 2021 and 2020. All available-for sale securities are carried at fair value and may be used for liquidity purposes should management consider it to be in our best interest.

The carrying value of the securities portfolio was $193 million, or 11.3% of total assets at June 30, 2022 as compared to $197 million, or 11.9% of total assets at December 31, 2021 and $169 million, or 10.8% of total assets at December 31, 2020.

Loans

We make loans and extensions of credit to individuals and a variety of firms and corporations located primarily in our markets in North and South metro Atlanta, Georgia, Southeastern Georgia and Northeastern Florida. Although we have a diversified loan portfolio, a substantial portion of our loan portfolio is collateralized by improved and unimproved real estate, the value of which is dependent upon the real estate market and the interest rate environment. Total loans, net of unearned income, as of June 30, 2022 were $1.111 billion compared to $1.055 billion as of December 31, 2021 and $1.068 billion as of December 31, 2020.

During 2020 and 2021, we modified loans for certain customers by extending payments for 90 days or granting interest only payments for some period as a result of the COVID-19 pandemic. Accordingly, under the CARES Act and related regulatory guidance, such loans were not classified as troubled debt restructurings. As of December 31, 2021, the extension period for these loans had expired with customers resuming their regular payment schedule.

The following table sets forth the composition of our loan portfolio, including both originated and acquired, as of June 30, 2022, December 31, 2021 and 2020:

Maturities and Sensitivity of Loans to Changes in Interest Rates

The information in the following table is based on the contractual maturities of individual loans, including loans that may be subject to renewal at their contractual maturity. Renewal of these loans is subject to review and credit approval, as well as modification of terms upon maturity. Actual repayments of loans may differ from the maturities reflected below because borrowers have the right to prepay obligations with or without prepayment penalties. The following table summarizes the loan maturity distribution by type and related interest rate characteristics at June 30, 2022:

Allowance for Loan Losses

We maintain the allowance for loan losses at a level we believe is sufficient to absorb probable incurred losses in our loan portfolio given the conditions at the time. Events that are not within our control, such as changes in economic factors, could change subsequent to the reporting date and could cause increases or decreases to the allowance. The amount of the allowance is affected by loan charge-offs, which decrease the allowance; recoveries on loans previously charged off, which increase the allowance; and the provision for credit losses charged to earnings, which increases the allowance.

In determining the provision for credit losses, management monitors fluctuations in the allowance resulting from actual charge-offs and recoveries and reviews the size and composition of the loan portfolio in light of current and anticipated economic conditions (see Notes 1 and 6 to our audited consolidated financial statements). This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available or as events change.

At June 30, 2022, the allowance was $15.3 million, or 1.38% of loans, a change from $15.2 million, or 1.44% of loans when compared to December 31, 2021 and $14.1 million, or 1.32% of loans at December 31, 2020. At June 30, 2022, management believes the allowance for loan losses was adequate and should any of the factors considered by management in determining the allowance for loan losses change, management’s estimate of losses in the portfolio could also change, which would affect the level of future provisions for loan losses.

Nonperforming Assets

We have established policies and procedures to guide us in originating, monitoring and maintaining the credit quality of our loan portfolios. These policies and procedures are required to be followed by our bankers and underwriters and exceptions to these policies require elevated levels of approval and are reported to our board of directors.

Nonperforming assets include all loans categorized as nonaccrual, other real estate owned and other repossessed assets. The accrual of interest on loans is discontinued, or the loan is placed on nonaccrual, when the full collection of principal and interest is in doubt. We do not accrue interest on loans that are 90 days or more past due. When a loan is placed on nonaccrual, previously accrued but unpaid interest is reversed and charged against interest income and future accruals of interest are discontinued. Payments by borrowers for loans on nonaccrual are applied to loan principal. Loans are returned to accrual status when, in our judgment, the borrower’s ability to satisfy principal and interest obligations under the loan agreement has improved sufficiently to reasonably assure recovery of principal and the borrower has demonstrated a sustained period of repayment performance. In general, we require a minimum of six consecutive months of timely payments in accordance with the contractual terms before returning a loan to accrual status. We do not consider our PCI loans to be nonperforming assets as long as their cash flows and the timing of such cash flows continue to be estimable and probable of collection, because we recognize interest income on these loans through accretion of the difference between the carrying value of these loans and the present value of expected future cash flows. As a result, management has excluded PCI loans from our presentation of nonperforming assets.

A loan is identified as a troubled debt restructuring, or TDR, when we, for economic or legal reasons related to the borrower’s financial difficulties, grant a concession to the borrower. The concessions may be

150

TABLE OF CONTENTS

granted in various forms including interest rate reductions, principal forgiveness, extension of maturity date, waiver or deferral of payments and other actions intended to minimize potential losses. A loan that has been restructured in a TDR may not be disclosed as a TDR in years subsequent to the restructuring if certain conditions are met. Generally, a nonaccrual loan that is restructured remains on nonaccrual status for a period no less than six months to demonstrate that the borrower can meet the restructured terms. However, the borrower’s performance prior to the restructuring or other significant events at the time of restructuring may be considered in assessing whether the borrower can meet the new terms and may result in the loan being returned to accrual status after a shorter performance period. If the borrower’s performance under the new terms is not reasonably assured, the loan remains classified as a nonaccrual loan.

The CARES Act, as extended by certain provisions of the Consolidated Appropriations Act, 2021, permitted banks to suspend requirements under GAAP for loan modifications to borrowers affected by COVID-19 that may otherwise be characterized as a TDR and suspended any determination related thereto if (i) the borrower was not more than 30 days past due as of December 31, 2019, (ii) the modifications were related to COVID-19, and (iii) the modification occurred between March 1, 2020 and January 1, 2022. Federal bank regulatory authorities also issued guidance to encourage banks to make loan modifications for borrowers affected by COVID-19. As of December 31, 2020, $10.3 million of restructured loans were exempt from the accounting guidance for TDRs as a result of loans which are included in the COVID-19 related loan payment deferral total. All of these customers returned to regular payment schedules prior to December 31, 2021.

The following table sets forth our nonperforming assets as of June 30, 2022, and as of December 31, 2021 and 2020:

Total nonperforming assets were $2.9 million as of June 30, 2022, compared to $2.6 million at December 31, 2021. The $343,000 increase was primarily a result of one workout relationship migrating to nonaccrual.

Total nonperforming assets were $2.6 million as of December 31, 2021, compared to $12.5 million at December 31, 2020. The $9.9 million decrease was primarily a result of the successful resolution of legacy problem loans in our coastal division and sales of various parcels of other real estate owned.

TABLE OF CONTENTS

The amount of interest that would have been recorded on nonaccrual loans, had the loans not been classified as nonaccrual, totaled $195,000 for the six months ended June 30, 2022, compared to $395,000 and $453,000 for the years ended December 31, 2021 and 2020, respectively. No interest income was recognized on nonaccrual loans for the six months ended June 30, 2022, or for the years ended December 31, 2021 and 2020.

Deposits

Deposits represent our primary source of funds. We are focused on growing our core deposits through relationship-based banking with our business and consumer clients. Total deposits increased to $1.486 billion at June 30, 2022, compared to $1.427 billion and $1.363 billion at December 31, 2021 and 2020, respectively. The growth was realized in our core transaction account base throughout the footprint as we intentionally exited from our single service, higher cost certificate of deposit clients.

The following table sets forth the average balance amounts and the average rates paid on deposits held by us for the periods ended June 30, 2022, December 31, 2021 and December 31, 2020:

Borrowings and Other Interest-Bearing Liabilities

Other than deposits, we also utilize Federal Home Loan Bank (FHLB) advances as a supplementary funding source to finance our operations. Our advances from the FHLB are collateralized by residential, multi-family real estate loans and securities. At June 30, 2022, December 31, 2021 and December 31, 2020, we

152

TABLE OF CONTENTS

had maximum borrowing capacity from the FHLB of $424 million, $410 million and $389 million, respectively, subject to the availability of collateral. We did not have any advances outstanding from December 31, 2020 through June 30, 2022.

The following tables outline our various sources of borrowed funds during the six months ended June 30, 2022 and the year ended December 31, 2021, and the amounts outstanding at the end of each period, the maximum month end amount for each component during the periods, the average amounts for each period, and the average interest rate that we paid for each borrowing source. The maximum month-end balance represents the high indebtedness for each component of borrowed funds at any time during each of the periods shown.

Liquidity

Liquidity refers to our ability to maintain cash flow that is adequate to fund operations, support asset growth, maintain reserve requirements and meet present and future obligations of deposit withdrawals, lending obligations and other contractual obligations. Our asset and liability management policy, or ALM policy, provides the framework that we use to maintain adequate liquidity and sources of available liquidity at levels that enable us to meet all reasonably foreseeable short-term, long-term and strategic liquidity demands. Our Asset and Liability Management Committee, or ALCO, is responsible for oversight of our liquidity risk management activities in accordance with the provisions of our ALM Policy and applicable bank regulatory capital and liquidity laws and regulations. Our liquidity risk management process includes (i) ongoing analysis and monitoring of our funding requirements under various economic and interest rate scenarios, (ii) review and monitoring of lenders, depositors, brokers and other liability holders to ensure appropriate diversification of funding sources and (iii) liquidity contingency planning to address liquidity needs in the event of unforeseen market disruption, including appropriate allocation of funds to a liquid portfolio of marketable securities and investments. We continuously monitor our liquidity position in order for our assets and liabilities to be managed in a manner that will meet our immediate and long-term funding requirements. We manage our liquidity position to meet the daily cash flow needs of customers, while maintaining an appropriate balance between assets and liabilities to meet the return on investment objectives of our shareholders. We also monitor our liquidity requirements in light of interest rate trends, changes in the economy, and the scheduled maturity and interest rate sensitivity of our securities and loan portfolios and deposits. Liquidity management is made more complicated because different balance sheet components are subject to varying degrees of management control. For example, the timing of maturities of our investment portfolio is fairly predictable and subject to a high degree of control when we make investment decisions. Net deposit inflows and outflows, however, are far less predictable and are not subject to the same degree of certainty.

Our liquidity position is supported by management of our liquid assets and liabilities and access to alternative sources of funds. Our short-term and long-term liquidity requirements are primarily to fund on-going operations, including payment of interest on deposits and debt, extensions of credit to borrowers and capital expenditures. These liquidity requirements are met primarily through our deposits, FHLB advances and the principal and interest payments we receive on loans and investment securities. Cash, interest-bearing deposits in third party banks, securities available for sale and maturing or prepaying balances in our

153

TABLE OF CONTENTS

investment and loan portfolios are our most liquid assets. Other sources of liquidity that are available to us include the sale of loans we hold for investment, the ability to acquire additional national market noncore deposits, borrowings through the Federal Reserve’s discount window and the issuance of debt or equity securities. We believe that the sources of available liquidity are adequate to meet our current and reasonably foreseeable future liquidity needs.

At June 30, 2022, our liquid assets, which consist of cash and amounts due from banks and interest-bearing deposits in other financial institutions, amounted to $266 million, or 7.2% of total assets, compared to $262 million, or 7.2% of total assets, at December 31, 2021. The increase in our liquid assets was primarily due to core deposit growth partly offset by net loan fundings. Our available-for-sale securities at June 30, 2022 were $193 million, or 11.3% of total assets, compared to $197 million, or 11.9% of total assets, at December 31, 2021. Investment securities with an aggregate fair value of $22.3 million and $24.0 million at June 30, 2022 and December 31, 2021, respectively, were pledged to secure public deposits and repurchase agreements. The increase in our unpledged securities was due to a decrease in repurchase agreements.

The liability portion of the balance sheet serves as our primary source of liquidity. We plan to meet our future cash needs through the generation of deposits. Customer deposits have historically provided a sizeable source of relatively stable and low-cost funds. At June 30, 2022, customer deposits, excluding time deposits greater than $250,000, were 129% of net loans, compared with 130% at December 31, 2021.

Capital Resources

Shareholders’ equity at June 30, 2022 was $150.0 million, compared to $154.0 million at December 31, 2021, a decrease of $4.0 million, or 2.6%. The decrease was primarily driven by an $11.0 million increase in accumulated comprehensive loss related to the effect of rising interest rates on the market value of our available-for-sale securities which was partially offset by net earnings of $7.2 million.

Shareholders’ equity at December 31, 2021 was $154.0 million, compared to $142.8 million at December 31, 2020, an increase of $11.1 million, or 7.8%. The increase was primarily driven by 2021 net earnings.

We are subject to various regulatory capital requirements administered by federal banking regulators. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by federal banking regulators that, if undertaken, could have a direct material effect on our financial statements.

Regulatory capital rules adopted in July 2013 and fully-phased in as of January 1, 2019, which we refer to as Basel III rules, impose minimum capital requirements for bank holding companies and banks. The Basel III rules apply to all national and state banks and savings associations regardless of size and bank holding companies and savings and loan holding companies with consolidated assets of more than $3 billion. In order to avoid restrictions on capital distributions or discretionary bonus payments to executives, a covered banking organization must maintain the fully-phased in “capital conservation buffer” of 2.5% on top of its minimum risk-based capital requirements. This buffer must consist solely of common equity Tier 1 risk-based capital, but the buffer applies to all three measurements (common equity Tier 1 risk-based capital, Tier 1 capital and total capital).

The following table shows the regulatory capital ratios for us at the dates indicated:

	Minimum Capital Adequacy with Capital Conservation Buffer, if applicable(1)		Well Capitalized Under Prompt Corrective Action Provisions(2)		June 30, 2022		December 31, 2021		December 31, 2020

Amounts are shown inclusive of a capital conservation buffer of 2.50%. Under the Federal Reserve’s Small Bank Holding Company Policy Statement, Heritage is not subject to the minimum capital adequacy and capital conservation buffer capital requirements at the holding company level, unless otherwise advised by the Federal Reserve (such capital requirements are applicable only at the Heritage Southeast Bank level). Although the minimum regulatory capital requirements are not applicable to Heritage, we calculate these ratios for our own planning and monitoring purposes.

Prompt corrective action provisions are only applicable at the Heritage Southeast Bank level.

Off-Balance Sheet items

We are a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of our customers. These financial instruments include commitments to extend credit, commercial letters of credit and standby letters of credit. Those instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated statements of financial condition. The contractual or notional amounts of those instruments reflect the extent of involvement we have in particular classes of financial instruments.

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amount does not necessarily represent future cash requirements. We evaluate each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by us upon extension of credit, is based on management’s credit evaluation of the counterparty. Collateral is primarily obtained in the form of commercial and residential real estate (including income producing commercial properties).

Standby letters of credit are conditional commitments issued by us to guarantee to a third-party the performance of a customer. Those guarantees are primarily issued to support public and private borrowing arrangements, bond financing and similar transactions. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers.

Commitments to make loans are generally made for periods of 90 days or less.

Our exposure to credit loss in the event of non-performance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual or notional amount of those instruments. We use the same credit policies in making commitments and conditional obligations as for funded instruments. We do not anticipate any material losses as a result of the commitments and standby letters of credit.

The following table summarizes commitments as of the dates presented.

DESCRIPTION OF CAPITAL STOCK OF THE FIRST BANCSHARES, INC.

As a result of the merger, HSBI shareholders who receive shares of First Bancshares common stock in the merger will become shareholders of First Bancshares. Your rights as shareholders of First Bancshares will be governed by Mississippi law and the First Bancshares Articles and the First Bancshares Bylaws. The following briefly summarizes the material terms of First Bancshares common stock. We urge you to read the applicable provisions of the Mississippi Business Corporation Act, or the MBCA, the First Bancshares Articles and First Bancshares Bylaws and federal laws governing bank holding companies carefully and in their entirety. Copies of First Bancshares’ governing documents have been filed with the SEC. 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 [ ], 2022, 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 twelve directors divided as follows: four Class I directors, four Class II directors, and four Class III directors. The terms of the Class I directors will expire at the 2023 Annual Shareholders’ Meeting. The terms of the Class II directors will expire at the 2024 Annual Shareholders’ Meeting. The terms of the Class III directors will expire at the 2025 Annual Shareholders’ Meeting, with the exception of one Class III director who must stand for re-election at the 2023 Annual Meeting because he was appointed by the Board to fill a newly-created position after the 2022 Annual 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 federal bank regulatory authorities, and federal bank regulatory authorities may prohibit the payment of dividends where it has determined that the payment of dividends would be an unsafe or unsound practice. The Federal Reserve has indicated that paying dividends that deplete a bank’s capital base to an inadequate level would be an unsound and unsafe banking practice. The Federal Reserve has indicated that depository institutions and their holding companies should generally pay dividends only out of current operating

earnings. Further, under Mississippi law, The First must obtain the non-objection of the Commissioner of the Mississippi Department of Banking and Consumer Finance prior to paying any dividend to First Bancshares.

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.

157

TABLE OF CONTENTS

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 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.

COMPARISON OF RIGHTS OF
FIRST BANCSHARES SHAREHOLDERS AND HSBI SHAREHOLDERS

If the merger is completed, shareholders of HSBI will become shareholders of First Bancshares. The rights of HSBI shareholders are currently governed by and subject to the provisions of Georgia Business Corporation Code, as amended, or the GBCC, and the HSBI Articles and HSBI Bylaws. Upon completion of the merger, the rights of the former HSBI shareholders who receive shares of First Bancshares common stock will be governed by the MBCA and the First Bancshares Articles and First Bancshares Bylaws, rather than the HSBI Articles and HSBI Bylaws.

The following is a summary of the material differences between the rights of holders of First Bancshares common stock and holders of HSBI stock, but it does not purport to be a complete description of those differences, the specific rights of such holders or the terms of the First Bancshares common stock subject to issuance in connection with the merger. The following summary is qualified in its entirety by reference to the relevant provisions of: (1) Mississippi and Georgia law; (2) the First Bancshares Articles; (3) the HSBI Articles; (4) the First Bancshares Bylaws; and (5) the HSBI Bylaws.

The identification of some of the differences in the rights of such holders as material is not intended to indicate that other differences that may be equally important do not exist. You are urged to read carefully the relevant provisions of Mississippi and Georgia law, as well as the governing corporate instruments of each of First Bancshares and HSBI, copies of which are available, without charge, to any person, including any beneficial owner to whom this joint proxy statement/prospectus is delivered, by following the instructions listed under “Where You Can Find More Information.”

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 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.

The HSBI Articles further provided that if the GBCC is amended to permit further indemnification of the directors, officers, employees, and agents of HSBI, then HSBI will indemnify such persons to the fullest extent permitted by the GBCC, as amended.
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.

			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 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			misconduct or knowing violations of law, for the types of liabilities described in Section 14-2-832 of the GBCC, or for transactions where the director derived an improper benefit. The HSBI Articles further provide that HSBI will not indemnify a director, officer, employee, or agent for any liability incurred in a legal action or proceeding initiated by or participated in as an intervenor or amicus curiae by the person seeking indemnification unless such initiation or participation in the legal action or proceeding is authorized by the affirmative vote of a majority of the directors then in office.

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 GBCC, a corporation may make a distribution, unless after giving effect to the distribution: (a) the corporation would not be able to pay its debts as they come due in the usual course of business; or (b) the corporation’s total assets would be less than the sum of its total liabilities plus (unless the articles of incorporation permit otherwise) the amount that would be needed, if the corporation 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 GBCC, the “fair value” of HSBI stock is the “the value of the shares immediately before the effectuation of the corporate action to which the dissenter objects, excluding any appreciation or depreciation in anticipation of the corporate action.” See “The Merger — Dissenters’ Rights for HSBI Shareholders” and Annex E.

280G PROPOSAL

HSBI shareholders are being asked to approve the 280G proposal in order that Brad Serff may avoid potential adverse tax consequences under Sections 280G and 4999 of the Code, as applicable.

In connection with the merger, Mr. Serff may receive certain compensatory payments that could have adverse tax consequences for Mr. Serff under Sections 280G and 4999 of the Code and the regulations and rulings promulgated thereunder, collectively referred to as the “golden parachute rules.” In connection with the closing of the merger, Mr. Serff’s existing employment agreement with HSBI and Heritage Southeast Bank (the “Existing Employment Agreement”) will be terminated pursuant to a termination agreement and a change in control cash payment will be made to Mr. Serff as set forth in the Existing Employment Agreement. Pursuant to Mr. Serff’s Existing Employment Agreement, if any payments or benefits received or to be received by Mr. Serff (including, any payment or benefit received in connection with a change in control or Mr. Serff’s termination of employment, whether pursuant to the employment agreement or other plan, arrangement, or agreement, or otherwise) constitute a “parachute payment” under Sections 280G and 4999 of the Code, then such “parachute payments” will be reduced in a manner determined by the HSBI board of directors by the minimum possible amount until no amount payable to Mr. Serff will be subject to the excise tax owed under Sections 280G and 4999 of the Code. If two economically equivalent amounts are subject to reduction but are payable at different times, the amount shall be reduced (but not below zero) on a pro rata basis. Such reductions will be made to any “parachute payment” if the 280G proposal is not approved by HSBI’s shareholders.

Golden Parachute Rules

Under the golden parachute rules, payments of compensation that are made to specified “disqualified individuals,” including officers, certain highly compensated individuals, and certain significant shareholders and equity holders, that (i) are treated as contingent on a change in control of a corporation and (ii) in the aggregate exceed three times the individual’s “base amount” (as determined in accordance with the golden parachute rules) minus $1.00, which we refer to as such individual’s “safe harbor” amount, may be characterized as “parachute payments” subject to adverse tax treatment. The base amount is generally an individual’s average annual taxable compensation from the corporation (or a related corporation) for the five years preceding the year of the change in control (or for the period of employment with the payor corporation if less than five years). All parachute payments in excess of one times the base amount are referred to as “excess parachute payments.” Mr. Serff is a disqualified individual.

Shareholder Vote Exception for Privately Held Corporations

In general, excess parachute payments are not deductible by the payor corporation and are subject to a 20% excise tax on the disqualified individual (in addition to any regular income taxes due with respect to such payments). However, an exception to the foregoing treatment applies in the case of payments made by non-publicly traded corporations like HSBI. In accordance with the golden parachute rules, Mr. Serff has entered into a waiver agreement pursuant to which he has waived his right to receive or retain a portion of his payments and benefits that equals or exceeds three times his base amount less $1 upon and following consummation of the merger unless such payments are approved by a separate vote of shareholders possessing more than 75% of the voting power of all outstanding stock of the corporation (excluding from both the numerator and the denominator in such calculation shares held by ineligible shareholders), and prior to such vote there is adequate disclosure to all shareholders entitled to vote of the material facts concerning such payments. We refer to the amount waived by Mr. Serff as his “waived amount”. HSBI is seeking shareholder approval with respect to Mr. Serff’s waived amount. The waiver will be void in the event the HSBI merger proposal is not approved by the HSBI shareholders or the merger agreement is terminated pursuant to its terms.

The discussion below sets forth the material facts of the payments to the disqualified individual and HSBI’s estimate of the value of the payments under the valuation rules set forth in the golden parachute rules, which value we refer to as the “estimated Section 280G value.” The calculation of the estimated Section 280G value of the payments under the golden parachute rules is highly complex, and issues often arise

171

TABLE OF CONTENTS

for which there is no authoritative guidance. Final values may only be determined after the merger has been consummated or upon other subsequent events. Accordingly, it is not certain if all of the payments described below would in fact constitute parachute payments or excess parachute payments. The values of the payments provided below should be viewed as estimates based upon what HSBI believes to be conservative interpretations of the golden parachute rules using information available on the date of this joint proxy statement/prospectus. In addition, the actual waived amount could be significantly more or less than the estimated waived amounts shown, depending on the facts, circumstances and legal determinations relating to the payments, including, without limitation, the actual amount of the safe harbor for the disqualified individual and/or a determination of the reasonable compensation for services actually rendered or refrained from after the date of the merger (the latter of which does not constitute a parachute payment).

As a result, the 280G proposal, if approved, will be in respect of the waived amounts as finally determined, rather than the estimated amounts described below.

Effect of Shareholder Vote

As provided above, Mr. Serff has waived any compensatory payment above the safe harbor amount that he may be entitled to receive in connection with the merger if the approval of the 280G proposal is not obtained which would operate to limit such amounts payable to Mr. Serff to the safe harbor amount. If the HSBI shareholders possessing more than 75% of the voting power approve the 280G proposal, Mr. Serff will be entitled to retain and/or receive the entire amount of his payments (including any waived amounts). If HSBI shareholders possessing more than 75% of the voting power do not approve the 280G proposal, then Mr. Serff will forfeit his Waived Amount and he will not receive or retain any portion of the Waived Amount.

The vote to approve the 280G proposal is entirely separate from, and not contingent or otherwise conditioned on, the vote to approve the HSBI merger proposal, and, while they may do so, shareholders that approve the HSBI merger proposal are not required to approve the 280G proposal. The ineligible shareholders (Mr. Serff and shareholders whose holdings would be attributed to Mr. Serff) hold 14,746 shares of HSBI common stock as of the date of this joint proxy statement/prospectus. These shares will not count in the voting with respect to the 280G proposal and will be disregarded in both the numerator and denominator in determining whether more than 75% of the voting power of the outstanding shares are voted in favor of the 280G proposal.

For purposes of the shareholder approval rules discussed above, any HSBI shareholder that is an entity shareholder may exercise its vote through any person authorized by such entity shareholder to approve the payment. But if the individual authorized to vote the entity shareholder’s shares is a disqualified individual, the entity must designate someone who is not a disqualified individual to vote the shares. Moreover, if a substantial portion of the assets of an entity shareholder consists (directly or indirectly) of the stock of HSBI (i.e., the fair market value of the HSBI common stock equals or exceeds 1/3 of the total gross fair market value of all of the assets of the entity shareholder) and the value of such stock is greater than 1% of the total value of the outstanding common stock of HSBI, the payments must be approved by separate vote of the persons who, immediately before the change in control, own more than 75% of the voting power of the entity shareholder in accordance with the normal voting rules of such entity shareholder.

Description of the Payments

Change in Control Payment under Existing Employment Agreement

Under Mr. Serff’s Existing Employment Agreement, if Mr. Serff’s employment with HSBI is terminated other than due to cause or his disability, or if Mr. Serff terminates his employment for good reason or retirement, Heritage Southeast Bank will pay Mr. Serff an amount equal to two times his base salary then in effect plus two times his average annual cash bonuses, if any, paid for the three most recent full calendar years. If Mr. Serff’s termination occurs not more than two years following a change in control, all severance payments owed to Mr. Serff would be paid in a lump sum. As described above, the Existing Employment Agreement will be terminated upon the closing of the merger pursuant to a termination agreement which will provide for a change in control cash payment to Mr. Serff of $821,102, equivalent to the severance otherwise due under the Existing Employment Agreement, as indicated in the table below.

172

TABLE OF CONTENTS

Disqualified Individual			Estimated Total Section 280G Value of the Change in Control Payment

Supplemental Executive Retirement Plans

Mr. Serff has an existing Supplemental Executive Retirement Benefits Agreement (SERP) with Heritage Southeast Bank. This plan provides for the payment of retirement benefits to Mr. Serff over a period of twenty years in certain circumstances. In connection with the merger, Mr. Serff has given his consent to The First terminating his SERP agreement effective as of the closing of the merger, and it is anticipated that The First will choose to terminate the SERP. Mr. Serff has also consented to any cash-based benefit owed to him being accelerated and paid to Mr. Serff in a single lump sum amount shortly following the closing of the merger. If The First terminates and pays out the SERP, the lump sum cash payment to Mr. Serff is estimated to be $1,553,826, which is equivalent to the present value of a twenty-year stream of payments under the SERP, discounted for his normal retirement age (age 65) to the date of the merger. Because the SERP becomes vested and is paid out in connection with the merger, the vesting acceleration and a portion of the payments could be treated as parachute payments for purposes of the golden parachute rules. The table below lists the total estimated Section 280G value that could be attributable to the vesting and payout of the SERP.

Disqualified Individual			Estimated Total Section 280G Value of the Vesting and Payout of the SERP
Brad Serff				$	473,005

Requested Shareholder Approval

The total estimated Section 280G value of the payments, the safe harbor amount, the excess parachute payments, and the estimated value of the waived amounts that shareholders of HSBI are being asked to approve for Mr. Serff are set forth in the following table:

Disqualified Individual			Estimated Total Section 280G Value of the Payments						Safe Harbor Amount						Estimated Excess Parachute Payments						Estimated Value of the Waived Amounts Submitted for Shareholder Approval under the 280G Proposal
Brad Serff				$	1,294,107					$	1,208,155					$	85,951					$	85,951

If the HSBI shareholders approve the 280G proposal as required under the golden parachute rules, Mr. Serff will retain his right to receive the full amount of his payments under the terms and conditions described above, and Mr. Serff will not be subject to the adverse tax consequences described above. If the HSBI shareholders do not approve the 280G proposal as required under the golden parachute rules, then the waived amounts will not be paid to or retained by Mr. Serff.

In order for HSBI shareholders to approve the 280G proposal, the holders of more than 75% of the voting power of the outstanding shares of HSBI common stock (excluding shares held by ineligible shareholders and related parties) must vote in favor of the 280G proposal.

THE HSBI BOARD OF DIRECTORS RECOMMENDS THAT HSBI SHAREHOLDERS VOTE “FOR” THE APPROVAL OF THE 280G PROPOSAL.

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 Corporation Code (the “GBCC”), at the Effective Time, HSBI shall merge with and into FBMS pursuant to the terms of this

TABLE OF CONTENTS

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 HSBI 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, Heritage Southeast Bank, a Georgia state-chartered bank and a direct wholly owned subsidiary of HSBI (“Heritage Southeast Bank”), shall be merged (the “Bank Merger”) with and into The First Bank, a Mississippi state-chartered bank and a direct wholly owned subsidiary of FBMS (“The First”), in accordance with the provisions of applicable federal and state banking laws and regulations, and The First shall be the surviving bank (the “Surviving Bank”). The Bank Merger shall have the effects as set forth under applicable federal and state banking laws and regulations, and FBMS and HSBI, as the sole shareholders of The First and Heritage Southeast Bank, respectively, have approved a separate merger agreement (the “Bank Plan of Merger”) in substantially the form attached hereto as Exhibit B, and have caused the Bank Plan of Merger to be executed and delivered by The First and Heritage Southeast 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, Heritage Southeast Bank shall continue to operate under its name; provided that prior to any such election, FBMS shall (a) reasonably consult with HSBI 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.

Section 1.04 Directors and Officers. The directors and officers of FBMS immediately prior to the Effective Time shall, from and after the Effective Time, continue as the directors and officers of the Surviving Entity until their successors shall have been duly elected, appointed, or qualified or until their earlier death, resignation, or removal in accordance with the charter and bylaws of the Surviving Entity. The directors and officers of The First immediately prior to the Effective Time of the Bank Merger shall, from and after the Effective Time, continue as the directors and officers of the Surviving Bank until their successors shall have been duly elected, appointed, or qualified or until their earlier death, resignation, or removal in accordance with the charter and bylaws of the Surviving Bank.

Section 1.05 Effective Time; Closing.

(a) Subject to the terms and conditions of this Agreement, the Parties will make all such filings as may be required to consummate the Merger and the Bank Merger by applicable Laws. The Merger shall become effective as set forth in the articles of merger (the “Articles of Merger”) related to the Merger, which will include the plan of merger (the “Plan of Merger”), that shall be filed with the Secretary of State of the State of Mississippi and the Secretary of State of the State of Georgia, as provided in the MBCA and GBCC, on the Closing Date. The “Effective Time” of the Merger shall be the later of (i) the date and time of filing of the Articles of Merger, or (ii) the date and time when the Merger becomes effective as set forth in the Articles of Merger, which shall be within thirty (30) days after all of the conditions to the Closing set forth in Article VI (other than those conditions that by their nature are to be satisfied by action taken at the Closing, which shall be satisfied or waived at the Closing) have been satisfied or waived (to the extent permitted by applicable law) in accordance with the terms hereof.

(b) The closing of the Merger contemplated by this Agreement (the “Closing”) shall take place on a date determined by FBMS and reasonably acceptable to HSBI (the “Closing Date”), which shall be on the first Business Day of the month that begins immediately following the satisfaction or waiver of the conditions to the Closing set forth in Article VI (other than those conditions that by their nature are to be satisfied by action taken at the Closing, which shall be satisfied or waived at the Closing) have been satisfied or waived (to the extent permitted by applicable Law) in accordance with the terms hereof, at the offices of Alston &

Section 1.06 Additional Actions. If, at any time after the Effective Time, any Party shall consider or be advised that any further deeds, documents, assignments or assurances in Law or any other acts are necessary or desirable to carry out the purposes of this Agreement (such Party, the “Requesting Party”), the other Party and its Subsidiaries and their respective officers and directors shall be deemed to have granted to the Requesting Party and its Subsidiaries, and each or any of them, an irrevocable power of attorney to execute and deliver, in such official corporate capacities, all such deeds, assignments or assurances in Law or any other acts as are necessary or desirable to carry out the purposes of this Agreement, and the officers and directors of the Requesting Party and its Subsidiaries, as applicable, are authorized in the name of the other Party and its Subsidiaries or otherwise to take any and all such action.

Section 1.07 Reservation of Right to Revise Structure. FBMS may at any time, without the approval of HSBI, change the method of effecting the business combination contemplated by this Agreement if and to the extent that it reasonably deems such a change to be necessary; provided, however, that no such change shall (i) alter or change the amount, form, or timing of the consideration to be issued to Holders as Merger Consideration, (ii) reasonably be expected to materially impede or delay consummation of the Merger, (iii) adversely affect the Tax treatment of the Holders in connection with the Merger, or (iv) require submission to or approval of HSBI’s shareholders after the Plan of Merger has been approved by HSBI’s shareholders. In the event that FBMS elects to make such a change, the Parties agree to cooperate to execute appropriate documents to reflect the change.

ARTICLE II

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 HSBI:

(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 HSBI Stock owned directly by FBMS, HSBI 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 “HSBI Cancelled Shares”).

(c) Notwithstanding anything in this Agreement to the contrary, all shares of HSBI 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 HSBI 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

A-3

TABLE OF CONTENTS

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. HSBI shall give FBMS (i) prompt notice of any written notices to exercise dissenters’ rights in respect of any shares of HSBI Stock, attempted withdrawals of such notices and any other instruments served pursuant to the GBCC and received by HSBI relating to dissenters’ rights and (ii) the opportunity to participate in negotiations and proceedings with respect to demands for fair value under the GBCC. HSBI 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 HSBI 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 HSBI Stock (excluding Dissenting Shares and HSBI 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 a number of shares of FBMS Common Stock equal to the Exchange Ratio (the “Merger Consideration”). The “Exchange Ratio” shall be 0.965 shares of FBMS Common Stock per share of HSBI Stock.

Section 2.02 HSBI Stock-Based Awards.

(a) At the Effective Time, each outstanding restricted stock award granted under the HSBI Stock Plans (an “HSBI Restricted Share”) shall, automatically and without any required action on the part of the holder thereof, become fully vested and cease to represent a restricted share of HSBI Common Stock and shall be converted into a number of shares of FBMS Common Stock equal to the product (with the result rounded down to the nearest whole number) of (i) the number of HSBI Restricted Shares subject to such award multiplied by (ii) the Exchange Ratio, with any fractional share being entitled to receive cash in lieu thereof as provided in Section 2.04 below.

(b) At the Effective Time, each right to acquire a share of HSBI Common Stock granted under an HSBI SERP Agreement, whether vested or unvested (an “HSBI SERP Share”) shall, automatically and without any required action on the part of the holder thereof, cease to represent an HSBI SERP Share and shall be converted into a number of shares of FBMS Common Stock equal to the product (with the result rounded up to the nearest whole number) of (i) the number of HSBI SERP Shares subject to such HSBI SERP Agreement multiplied by (ii) the Exchange Ratio, with any fractional share being entitled to receive cash in lieu thereof as provided in Section 2.04 below.

(c) At the Effective Time, each HSBI Option that is outstanding immediately prior to the Effective Time shall, automatically and without any required action on the part of the holder thereof, be converted into the right to receive an amount of cash equal to the product of (A) the excess, if any, of (1) the product of (x) the Exchange Ratio, multiplied by (y) the Initial FBMS Market Price, over (2) the per share exercise price of the HSBI Option prior to the Effective Time, multiplied by (B) the number of shares of HSBI Common Stock subject to such HSBI Option prior to the Effective Time, rounding up to the nearest cent.

(d) Prior to the Effective Time, HSBI, the HSBI Board and the compensation committee of the HSBI Board, as applicable, shall adopt any resolutions and take any actions that are necessary to effectuate the treatment of the HSBI Restricted Shares, the HSBI Options, and the HSBI SERP Shares pursuant to Section 2.02(a), Section 2.02(b) and Section 2.02(c). HSBI 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 HSBI Common Stock or other capital stock of HSBI to any person pursuant to or in settlement of the HSBI Restricted Shares, the HSBI Options, or the HSBI SERP Shares.

At the Effective Time, all shares of HSBI 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 HSBI 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 HSBI Common Stock shall

TABLE OF CONTENTS

cease to be, and shall have no rights as, shareholders of HSBI, 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 HSBI shall be closed, and there shall be no registration of transfers on the stock transfer books of HSBI of shares of HSBI 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 and the Bank Merger shall each 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 for each of the Merger and the Bank Merger.

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”).

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 and cash sufficient to deliver the aggregate 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 HSBI 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 HSBI 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 HSBI 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 FBMS 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 HSBI 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 HSBI 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

A-5

TABLE OF CONTENTS

the stock transfer books of HSBI 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 HSBI 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 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 HSBI Common Stock that is not registered in the stock transfer records of HSBI, the proper amount of cash and/or shares of FBMS Common Stock shall be paid or 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 HSBI Common Stock shall be properly endorsed or otherwise be in proper form for transfer and the person requesting such payment or issuance shall pay any transfer or other similar Taxes required by reason of the payment or 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 HSBI Common Stock issued and outstanding prior to the Effective Time shall be increased or decreased, or changed into or exchanged for a different number or 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 Exchange Ratio to give holders of HSBI Common Stock the same economic effect as contemplated by this Agreement prior to such event.

Section 3.12 HSBI Material Contracts; Defaults.

(a) Other than the HSBI Benefit Plans or as listed in the HSBI Disclosure Schedule 3.12, neither HSBI nor any of its Subsidiaries is a party to, bound by or subject to any agreement, contract, arrangement, commitment or understanding (whether written or oral) (i) which would entitle any present or former director, officer, employee, consultant or agent of HSBI or any of its Subsidiaries to indemnification from HSBI or any of its Subsidiaries; (ii) which grants any right of first refusal, right of first offer or similar right with respect to any assets or properties of HSBI or its respective Subsidiaries; (iii) related to the borrowing by HSBI or any of its Subsidiaries of money other than those entered into in the Ordinary Course of Business and any guaranty of any obligation for the borrowing of money, excluding endorsements made for collection, repurchase or resell agreements, letters of credit and guaranties made in the Ordinary Course of Business; (iv) which provides for payments to be made by HSBI or any of its Subsidiaries upon a change in control thereof; (v) relating to the lease of personal property having a value in excess of $25,000 individually or $75,000 in the aggregate; (vi) relating to any joint venture, partnership, limited liability company agreement or other similar agreement or arrangement; (vii) which relates to capital expenditures and involves future payments in excess of $50,000 individually or $125,000 in the aggregate; (viii) which relates to the disposition or acquisition of assets or any interest in any business enterprise outside the Ordinary Course of Business; (ix) which is not terminable on sixty (60) days or less notice and involving the payment of more than $30,000 per annum; (x) which contains a non-compete or client or customer non-solicit requirement or any other provision that restricts the conduct of any line of business by HSBI or any of its Affiliates or upon consummation of the Merger will restrict the ability of the Surviving Entity or any of its Affiliates to engage in any line of business (including, for the avoidance of doubt, any exclusivity provision granted in favor of any third party) or which grants any right of first refusal, right of first offer or similar right or that limits or purports to limit the ability of HSBI or any of its Subsidiaries (or, following consummation of the transactions contemplated hereby, FBMS or any of its Subsidiaries) to own, operate, sell, transfer, pledge or otherwise dispose of any assets or business; or (xi) pursuant to which HSBI or any of its Subsidiaries may become obligated to invest in or contribute capital to any entity. Each contract, arrangement, commitment or understanding of the type described in this Section 3.12(a) is listed in HSBI Disclosure Schedule 3.12(a), and is referred to herein as a “HSBI Material Contract.” HSBI has previously made available to FBMS true, complete and correct copies of each such HSBI Material Contract, including any and all amendments and modifications thereto.

(b) Each HSBI Material Contract is valid and binding on HSBI and any of its Subsidiaries to the extent such Subsidiary is a party thereto, as applicable, and is in full force and effect and enforceable in accordance with its terms (assuming the due execution by each other party thereto, provided that HSBI hereby represents and warrants that, to its Knowledge, each HSBI Material Contract is duly executed by all such parties), subject to the Enforceability Exception and except where the failure to be valid, binding, enforceable and in full force and effect, individually or in the aggregate, is not reasonably likely to have a Material Adverse Effect with respect to HSBI; and, neither HSBI nor any of its Subsidiaries is in material default under any HSBI Material Contract, and there has not occurred any event that, with the lapse of time or the giving of notice or both, would constitute such a material default.

has HSBI or any of its Subsidiaries been advised by any Governmental Authority that it is considering issuing, initiating, ordering, requesting, recommending or otherwise proceeding with (or is considering the appropriateness of any of the aforementioned actions) any HSBI Regulatory Agreement. To HSBI’s Knowledge, there are no investigations relating to any regulatory matters pending before any Governmental Authority with respect to HSBI or any of its Subsidiaries.

Section 3.14 Brokers; Fairness Opinion. Neither HSBI nor any of its officers, directors or any of its Subsidiaries has employed any broker or finder or incurred, nor will it incur, any liability for any broker’s fees, commissions or finder’s fees in connection with any of the transactions contemplated by this Agreement, except that HSBI has engaged, and will pay a fee or commission to Piper Sandler & Co. (“HSBI Financial Advisor”), in accordance with the terms of a letter agreement between HSBI Financial Advisor and HSBI, a true, complete and correct copy of which has been previously delivered by HSBI to FBMS. HSBI has received the opinion of the HSBI Financial Advisor (and, when it is delivered in writing, a copy of such opinion will be promptly provided to FBMS) to the effect that, as of the date of this Agreement and based upon and subject to the qualifications and assumptions set forth therein, the Merger Consideration is fair, from a financial point of view, to the holders of shares of HSBI Common Stock, and, as of the date of this Agreement, such opinion has not been withdrawn, revoked or modified.

Section 3.15 Employee Benefit Plans.

(a) HSBI Disclosure Schedule 3.15(a) sets forth a true and complete list of each HSBI Benefit Plan. For purposes of this Agreement, “HSBI Benefit Plans” means all material benefit and compensation plans, contracts, policies or arrangements (i) covering current or former employees of HSBI or any of its Subsidiaries (such current employees collectively, the “HSBI Employees”) or their beneficiaries and dependents, (ii) covering current or former directors of HSBI or any of its Subsidiaries or their beneficiaries and dependents, or (iii) with respect to which HSBI or any of its Subsidiaries has or may have any liability or contingent liability (including liability arising from ERISA Affiliates) including “employee benefit plans” within the meaning of Section 3(3) of ERISA, health/welfare, employment, severance, change-of-control, fringe benefit, deferred compensation, defined benefit plan, defined contribution plan, stock option, stock purchase, stock appreciation rights, stock based, incentive, bonus, retirement, and other policies, plans or arrangements, whether or not subject to ERISA.

(b) With respect to each HSBI Benefit Plan, HSBI has provided to FBMS true and complete copies of current plan documents for such HSBI Benefit Plan, any trust instruments, and insurance contracts or other funding arrangements forming a part of such HSBI Benefit Plan and all amendments thereto, all current summary plan descriptions and summary of material modifications, IRS Form 5500 for the three (3) most recently completed plan years (if applicable), the most recent IRS determination, opinion, notification or advisory letters (if applicable), with respect thereto, and any material correspondence from any regulatory agency. In addition, with respect to the HSBI Benefit Plans for the three (3) most recently completed plan years, any plan financial statements and accompanying accounting reports, service contracts, fidelity bonds and employee and participant annual QDIA notice, safe harbor notice, or fee disclosures notices under 29 CFR 2550.404a-5, and nondiscrimination testing data and results under Code Sections 105(h), 125, 129, 401(k), and 401(m), as applicable, have been provided to FBMS.

(c) All HSBI Benefit Plans are in compliance in all material respects in form and operation with all applicable Laws, including ERISA and the Code. Each HSBI Benefit Plan which is intended to be qualified under Section 401(a) of the Code (an “HSBI 401(a) Plan”), is so qualified and has received a favorable opinion, determination or advisory letter from the IRS, and, to HSBI’s Knowledge, there is not any circumstance that could reasonably be expected to result in revocation of any such favorable determination, opinion or advisory letter or the loss of the qualification of such HSBI 401(a) Plan under Section 401(a) of the Code, and nothing has occurred that would be expected to result in an HSBI 401(a) Plan ceasing to be qualified under Section 401(a) of the Code. All HSBI Benefit Plans have been administered in accordance, in all material respects, with their terms. There is no pending or, to HSBI’s Knowledge, threatened litigation or regulatory action relating to the HSBI Benefit Plans. Neither HSBI nor any of its Subsidiaries has engaged in a transaction with respect to any HSBI Benefit Plan, including an HSBI 401(a) Plan, that could subject HSBI or any of its Subsidiaries to a material tax or penalty under any Law including Section 4975 of the Code or Section 502(i) of ERISA. No HSBI 401(a) Plan has been submitted under or been the subject of an IRS voluntary compliance program submission that is still outstanding or that has not been fully

A-13

corrected in accordance with a compliance statement issued by the IRS with respect to any applicable failures. There are no audits, inquiries or proceedings pending or, to HSBI’s Knowledge, threatened by the IRS or the Department of Labor with respect to any HSBI Benefit Plan. To HSBI’s Knowledge, there are no current, pending, or threatened investigations by the IRS or the Department of Labor with respect to any HSBI Benefit Plan.

(d) No liability under Title IV of ERISA or Section 412 of the Code has been or is expected to be incurred by HSBI, any of its Subsidiaries or any ERISA Affiliates with respect to any ongoing, frozen or terminated “single employer plan,” within the meaning of Section 4001(a)(15) of ERISA, currently or formerly maintained by HSBI, any of its Subsidiaries or any of HSBI’s related organizations described in Code Sections 414(b), (c), (m), or (o), or any entity which is considered one employer with HSBI or any of its Subsidiaries under Section 4001 of ERISA or Section 414 of the Code (“ERISA Affiliates”). Neither HSBI nor any ERISA Affiliate has within the past ten (10) years maintained, sponsored, or contributed to, or been obligated to contribute to, a plan subject to Title IV of ERISA or Section 412 of the Code. None of HSBI or any ERISA Affiliate has contributed to (or been obligated to contribute to) a “multiemployer plan” within the meaning of Section 3(37) of ERISA at any time. Except as set forth on HSBI Disclosure Schedule 3.15(d), neither HSBI nor any of its Subsidiaries or ERISA Affiliates have incurred, and there are no circumstances under which they could reasonably be expected to incur, liability under Title IV of ERISA (regardless of whether based on contributions of an ERISA Affiliate) or Section 412 of the Code. Neither HSBI nor any of its Subsidiaries has within the past ten (10) years sponsored, maintained or participated in a multiple employer welfare arrangement as defined in ERISA Section 3(40). To HSBI’s Knowledge, no notice of a “reportable event” within the meaning of Section 4043 of ERISA has been required to be filed for any HSBI Benefit Plan or by any ERISA Affiliate or will be required to be filed, in either case, in connection with the transactions contemplated by this Agreement.

(e) All contributions required to be made with respect to all HSBI Benefit Plans have been timely made. No HSBI Benefit Plan or single employer plan of an ERISA Affiliate has an “accumulated funding deficiency” (whether or not waived) within the meaning of Section 412 of the Code or Section 3012 of ERISA and no ERISA Affiliate has an outstanding funding waiver.

(f) No HSBI Benefit Plan provides life insurance, medical, surgical, hospitalization or other employee welfare benefits to any HSBI Employee, or any of their affiliates, upon or following his or her retirement or termination of employment for any reason, except as may be required by Law (which, in some cases, may be company-paid).

(g) All HSBI Benefit Plans that are group health plans have been operated in all material respects in compliance with the group health plan continuation requirements of Section 4980B of the Code and all other applicable sections of ERISA and the Code, and no material liabilities arising under Code Section 4980H have occurred. HSBI may amend or terminate any such HSBI Benefit Plan at any time without incurring any liability thereunder for future benefits coverage at any time after such termination (other than expenses incurred but not yet reported or coverage required by Code Section 4980B).

(h) Except as otherwise provided for in this Agreement or as set forth in HSBI Disclosure Schedule 3.15(h), neither the execution of this Agreement, shareholder approval of this Agreement nor consummation of any of the transactions contemplated by this Agreement (individually or in conjunction with any other event), will (i) entitle any current or former HSBI Employee to retention or other bonuses, parachute payments, non-competition payments, or any other payment, (ii) entitle any current or former HSBI Employee to unemployment compensation, severance pay or any increase in severance pay upon any termination of employment, (iii) accelerate the time of payment or vesting (except as required by Law) or trigger any payment or funding (through a grantor trust or otherwise) of compensation or benefits under, increase the amount payable under, or trigger any other obligation pursuant to, any of the HSBI Benefit Plans, (iv) result in any breach or violation of, or a default under, any of the HSBI Benefit Plans, (v) result in any payment of any amount that would, individually or in combination with any other such payment, be an excess “parachute payment” to a “disqualified individual” as those terms are defined in Section 280G of the Code, or (vi) limit or restrict the right of HSBI or, after the consummation of the transactions contemplated hereby, FBMS or any of its Subsidiaries, to merge, amend or terminate any of the HSBI Benefit Plans.

In the event that there is present at such meeting, in person or by proxy, sufficient favorable voting power to secure the Requisite HSBI Shareholder Approval, HSBI will not adjourn or postpone the HSBI Meeting unless HSBI is advised by counsel that failure to do so would reasonably be expected to result

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

(a) FBMS and HSBI 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). HSBI shall use its reasonable best efforts to deliver to FBMS such financial statements and related analysis of HSBI, including “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of HSBI, 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 45 days of the date of this Agreement, FBMS shall file with the SEC the Registration Statement. Each of FBMS and HSBI 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. HSBI agrees to cooperate with FBMS and FBMS’s counsel and accountants in requesting and obtaining appropriate opinions, consents and letters from HSBI’s independent auditors in connection with the Registration Statement and the Proxy Statement-Prospectus. After the Registration Statement is declared effective under the Securities Act, FBMS shall cause the Proxy Statement-Prospectus to be printed at FBMS’s own expense, and HSBI and FBMS, at their own expense, shall promptly mail or cause to be mailed the Proxy Statement-Prospectus to their respective shareholders.

(b) FBMS will advise HSBI, 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 HSBI 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 HSBI 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 HSBI to mail such amendment or supplement to HSBI shareholders (if required under applicable Law).

FBMS and HSBI 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 HSBI to any Governmental Authority in connection with the transactions contemplated by this Agreement. Each Party shall have 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 made in connection with the transactions contemplated by this Agreement with any Governmental Authority. In addition, FBMS and HSBI shall each furnish to the other for review a copy of each such filing made in connection with the transactions contemplated by this Agreement with any Governmental Authority prior to its filing.

The Parties and their representatives will consult as often as practicable under the circumstances so as to permit HSBI 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 HSBI 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

(b) For the purposes of verifying the representations and warranties of the other and preparing for the Merger and the other matters contemplated by this Agreement, during the period of time from the date of this Agreement to the Effective Time, upon reasonable notice and subject to applicable Laws, FBMS agrees to furnish to HSBI and its authorized representatives such information as HSBI may reasonably request concerning the business of FBMS and its Subsidiaries that is substantially similar in scope to the information provided to HSBI in connection with its diligence review prior to the date of this Agreement.

(c) As promptly as reasonably practicable after they become available, HSBI will furnish to FBMS copies of the board packages distributed to the board of directors of HSBI or any of its Subsidiaries, and approved minutes from the meetings thereof, copies of any internal management financial control reports provided to the board of directors of HSBI or any of its Subsidiaries showing actual financial performance against plan and previous period, and copies of any reports provided to the board of directors of HSBI or any committee thereof relating to the financial performance and risk management of HSBI.

(d) During the period from the date of this Agreement to the Effective Time, at the reasonable request of either Party, the other Party will cause one or more of its designated representatives to confer with representatives of the requesting Party and to report the general status of the ongoing operations of the other Party and its Subsidiaries. Without limiting the foregoing, HSBI agrees to provide to FBMS (i) a copy of each report filed by HSBI or any of its Subsidiaries with a Governmental Authority (other than reports related to subpoenas, levies, and garnishments), (ii) a copy of HSBI’s monthly loan trial balance, and (iii) a copy of HSBI’s monthly statement of condition and profit and loss statement and, if requested by FBMS, a copy of HSBI’s daily statement of condition and daily profit and loss statement, in each case, which shall be provided as promptly as reasonably practicable after it is filed or prepared, as applicable. HSBI further agrees to provide FBMS, no later than ten (10) Business Days following the end of each calendar month following the date hereof, any supplements to HSBI Disclosure Schedule 3.19, HSBI Disclosure Schedule 3.22(a), and HSBI Disclosure Schedule 3.22(b) that would be required if the references to December 31, 2021 in each corresponding representation and warranty of HSBI were changed to the date of the most recently ended calendar month.

(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 HSBI to consummate the transactions contemplated hereby.

(f) Notwithstanding anything to the contrary in this Section 5.08, HSBI 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 HSBI’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 HSBI’s attorney-client privilege. In the event any of the restrictions in this Section 5.08(f) shall apply, HSBI 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.

Section 5.09 No Solicitation by HSBI; Superior Proposals.

(a) Except as permitted by Section 5.09(b), HSBI 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 HSBI or any of HSBI’s Subsidiaries (collectively, the “HSBI 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 HSBI 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 HSBI 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 HSBI Representatives, whether or not such HSBI Representative is so authorized and whether or not such HSBI Representative is purporting to act on behalf of HSBI or otherwise, shall be deemed to be a breach of this Agreement by HSBI. HSBI and its Subsidiaries shall, and shall cause each of the HSBI 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.

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 HSBI 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 HSBI or any of its Subsidiaries constituting, in the aggregate, 20% or more of the fair value of the consolidated assets of HSBI; (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 HSBI 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 HSBI 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 HSBI or any of its Subsidiaries, the shareholders of such third party) acquiring, directly or indirectly, more than 50% of the outstanding HSBI Common Stock or more than 50% of the assets of HSBI and its Subsidiaries (measured as a percentage of the fair value of the consolidated assets of HSBI), taken as a whole, for consideration consisting of cash and/or securities and (ii) that the board of directors of HSBI 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(c), and all financial, legal,

A-37

TABLE OF CONTENTS

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 HSBI 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 HSBI Meeting, HSBI may take any of the actions described in Section 5.09(a) if, but only if, (i) HSBI 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 HSBI 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) HSBI 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 HSBI or any of its Subsidiaries or otherwise relating to an Acquisition Proposal, HSBI receives from such Person a confidentiality agreement with terms no less favorable to HSBI than those contained in the confidentiality agreement with FBMS. HSBI shall promptly provide to FBMS any non-public information regarding HSBI 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) HSBI shall promptly (and in any event within forty-eight (48) 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, HSBI or the HSBI 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). HSBI agrees that it shall keep FBMS 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(d), neither the board of directors of HSBI nor the board of directors of any Subsidiary nor any committee of any boards of directors of HSBI 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 HSBI 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 HSBI 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 HSBI Recommendation within three (3) Business Days following a request by FBMS, or make any statement, filing or release, in connection with the HSBI Meeting or otherwise, inconsistent with the HSBI Recommendation, or (vi) resolve to do any of the foregoing. Each such action set forth in this Section 5.09(c) shall be referred to herein as an “Adverse Recommendation Action.”

(d) Notwithstanding any other provision in Section 5.09 or this Agreement, prior to the receipt of the Requisite HSBI Shareholder Approval, the board of directors of HSBI may withdraw, qualify, amend or modify the HSBI Recommendation (a “HSBI Subsequent Determination”) or cause or permit HSBI 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 Business Day following FBMS’s receipt of a notice (the “Notice of Superior Proposal”) from HSBI advising FBMS that the board of directors of HSBI 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 HSBI has determined in good

A-38

TABLE OF CONTENTS

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 HSBI’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”), HSBI and the board of directors of HSBI 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 HSBI to proceed with the HSBI Recommendation without a HSBI 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 HSBI 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, HSBI 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.

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 pay, compensate, and reimburse and defend, indemnify and hold harmless the present and former directors and officers of HSBI and its Subsidiaries (each an “Indemnified Party”), for and 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 threatened or actual claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative (each a “Claim”) (including advancement of reasonable attorney’s fees and expenses prior to the final disposition of any Claim to each Indemnified Party to the fullest extend permitted by Law upon receipt of any undertaking required by applicable law), arising out of actions or omissions of such persons in the course of performing their duties for HSBI 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 fullest extent such Indemnified Parties had the right to be indemnified and/or have the right to advancement of expenses pursuant to (x) the organizational documents of HSBI and its Subsidiaries in effect on the date of this Agreement and (y) the GBCC or other applicable Law, in each case to the fullest 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 HSBI Indemnified Party, in each case to the extent permitted by the FBCA (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 HSBI 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 were 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, except as provided in Section 5.10(b), 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

TABLE OF CONTENTS

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, and such determination shall have become final, 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 HSBI 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 the same coverage and amounts, and contain terms and conditions no less advantageous to the Indemnified Party, as that coverage currently provided by HSBI; 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 HSBI 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. The parties shall work together, in good faith, to obtain the best possible premium rate for such insurance, provided, however, that in no event shall FBMS be required to expend for such tail insurance a premium amount in excess of an amount equal to 250% of the annual premiums paid by HSBI 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 HSBI 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 full time employees of HSBI 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 HSBI (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 HSBI), 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 HSBI Benefit Plan in which such Covered Employee participated immediately prior to the Effective Time, and (ii) recognize

A-40

TABLE OF CONTENTS

any health, dental, vision or other welfare expenses incurred by such Covered Employee in the year that includes the Closing Date (or, if later, the year in which such Covered Employee is first eligible to participate) for purposes of any applicable deductible and annual out-of-pocket expense requirements under such health, dental, vision or other welfare plan.

(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 Heritage Southeast Bank 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) HSBI shall cause Heritage Southeast Bank to take all necessary actions to terminate in the Heritage Southeast Bank 401(k) Plan (the “Heritage Southeast Bank 401(k) Plan”), effective as the date immediately preceding the Effective Time of the Merger, subject to the occurrence of the Effective Time. HSBI shall provide FBMS with evidence that the Heritage Southeast Bank 401(k) Plan has been terminated and provide copies of the appropriate resolutions (the form and substance of which shall be subject to review and approval by FBMS, which will not be unreasonably withheld) not later than 5 days preceding the Effective Time.

The Parties shall report the Merger for all Tax purposes in a manner consistent with such qualification.

(b) FBMS shall prepare and file or cause to be prepared and filed all Tax Returns for HSBI and its Subsidiaries for all periods ending on or prior to the Closing Date that are due to be filed after the Closing Date.

Such vote shall establish the “disqualified individual’s” right to the payment or other compensation. In addition, prior to such shareholder vote, HSBI shall (i) provide adequate disclosure to all shareholders of HSBI entitled to vote of all material facts concerning all payments that, but for such vote, could be deemed “parachute payments” to a “disqualified individual” under Section 280G of the Code in a manner that satisfies Section 280G(b)(5) of the Code, and (ii) obtain from each “disqualified individual” who is entitled to receive payments that could be deemed “parachute payments” under Section 280G of the Code a written waiver of his or her rights to such payments in the event of a failure to approve the payments by at least 75% of the HSBI shares entitled to vote.

(b) HSBI 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 HSBI fails promptly to pay any amounts due under this Section 7.02, HSBI 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.

(c) Notwithstanding anything to the contrary set forth in this Agreement, the Parties agree that if HSBI pays or causes to be paid to FBMS the Termination Fee in accordance with Section 7.02(a), HSBI (or any successor in interest of HSBI) will not have any further obligations or liabilities to FBMS with respect to this Agreement or the transactions contemplated by this Agreement.

Section 7.03 Effect of Termination. Except as set forth in Section 7.02(c), termination of this Agreement will not relieve a breaching party from liability for any breach of any covenant, agreement, representation or warranty of this Agreement (a) giving rise to such termination and (b) resulting from fraud or any willful and material breach.

NON-COMPETITION AND NON-DISCLOSURE AGREEMENT

This Non-Competition and Non-Disclosure Agreement (the “Agreement”) is dated as of July 27, 2022, by and between the undersigned, an individual (“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 Heritage Southeast Bancorporation, Inc., a Georgia corporation (“HSBI”), 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) HSBI will merge with and into FBMS, with FBMS as the surviving entity, and (ii) Heritage Southeast Bank, a Georgia state-chartered bank and wholly-owned subsidiary of HSBI (“Heritage Southeast Bank”), will merge with and into The First Bank, a Mississippi state-chartered bank and wholly-owned subsidiary of FBMS (“The First”), with The First as the surviving bank (collectively, the “Merger”);

WHEREAS, Director is a shareholder of HSBI 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 HSBI 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 HSBI and /or Heritage Southeast Bank, and, therefore, Director has knowledge of the Confidential Information and Trade Secrets (each as hereinafter defined);

WHEREAS, as a result of the Merger, The First and 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 HSBI and Heritage Southeast 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, upon advice of his or her counsel, required to disclose Confidential Information, disclosure may be made only as to that portion of the Confidential Information that counsel advises Director 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

A-81

TABLE OF CONTENTS

Commission or any other federal, state or local governmental agency or commission that has or had jurisdiction over HSBI 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 HSBI or any of its subsidiaries or affiliates or any successors thereto. 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 one (1) year 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, HSBI or Heritage Southeast Bank (each a “Protected Party”), including prospective customers of Heritage Southeast Bank actually known by Director to be actively sought by Heritage Southeast 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; provided that the foregoing will not prevent the placement of any general solicitation not specifically directed towards customers of any Protected Party or providing products or services as a result thereof.

(iii) 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, 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 HSBI and its Subsidiaries, including Heritage Southeast 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 HSBI and/or Heritage Southeast Bank;

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

(D) to the knowledge of Director not generally known to competitors of HSBI or FBMS (including competitors to Heritage Southeast Bank or The First).

A-82

TABLE OF CONTENTS

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 HSBI or FBMS, (y) has been independently developed and disclosed by others, or (z) has otherwise entered the public domain through lawful means.

(iii) “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. This Agreement may be terminated at any time by the written consent of the parties hereto, and this Agreement shall be automatically terminated upon the earlier of (i) termination of the Merger Agreement and (ii) two (2) years following the Effective Time. For the avoidance of doubt, the provisions of Section 1 shall only become operative upon the consummation of the Merger but, in such event, shall survive the consummation of the Merger until two (2) years after the Effective Time. Upon termination of this Agreement, no party shall have any further obligations or liabilities hereunder, except that termination of this Agreement will not relieve a breaching party from liability for any breach of any provision of this Agreement occurring prior to the termination of this Agreement.

Section 3. Notices. All notices, requests and other communications hereunder to a party shall be in writing and shall be deemed properly given if delivered (a) personally, (b) by registered or certified mail (return receipt requested), with adequate postage prepaid thereon, (c) by properly addressed electronic mail delivery (with confirmation of delivery receipt), or (d) by reputable courier service to such party at its address set forth below, or at such other address or addresses as such party may specify from time to time by notice in like manner to the parties hereto.

Heritage Southeast Bancorporation, Inc.

Jonesboro, GA 30236

Ladies and Gentlemen:

Heritage Southeast Bancorporation, Inc. (“HSBI”) and The First Bancshares, Inc. (“FBMS”) are proposing to enter into an Agreement and Plan of Merger (the “Agreement”) pursuant to which HSBI will, on the terms and subject to the conditions set forth in the Agreement, merge with and into FBMS with FBMS as the surviving corporation (the “Merger”). As set forth in the Agreement, at the Effective Time, each share of HSBI Common Stock issued and outstanding immediately prior to the Effective Time, except for certain shares of HSBI Common Stock as specified in the Agreement, by virtue of the Merger and without any action on the part of the holder thereof, shall be converted into and exchanged for the right to receive 0.965 shares of FBMS Common Stock (such consideration, the “Merger Consideration”). Capitalized terms used herein without definition shall have the meanings ascribed thereto in the Agreement. You have requested our opinion as to the fairness, from a financial point of view, of the Merger Consideration to the holders of HSBI Common Stock.

Piper Sandler & Co. (“Piper Sandler”, “we” or “our”), as part of its investment banking business, is regularly engaged in the valuation of financial institutions and their securities in connection with mergers and acquisitions and other corporate transactions. In connection with this opinion, we have reviewed and considered, among other things: (i) a draft of the Agreement, dated July 25, 2022; (ii) certain publicly available financial statements and other historical financial information of HSBI and its banking subsidiary, Heritage Southeast Bank, that we deemed relevant; (iii) certain publicly available financial statements and other historical financial information of FBMS that we deemed relevant; (iv) internal net income estimates for HSBI for the years ending December 31, 2022 through December 31, 2024 with an annual net income growth rate for the years ending December 31, 2025 and December 31, 2026, as provided by and confirmed with the senior management of HSBI; (v) publicly available mean analyst net income and dividend per share estimates for FBMS for the years ending December 31, 2022 and December 31, 2023, as provided by the senior management of FBMS, as well as a long-term annual earnings per share growth rate and estimated dividends per share for FBMS for the years ending December 31, 2024 through December 31, 2026, as provided by the senior management of FBMS; (vi) the pro forma financial impact of the Merger on FBMS based on certain assumptions relating to transaction expenses, purchase accounting adjustments and cost savings, as well as an estimated net income growth rate for HSBI for the years ending December 31, 2025 and December 31, 2026, as provided by the senior management of FBMS; (vii) the publicly reported historical price and trading activity for HSBI Common Stock and FBMS Common Stock, including a comparison of certain stock trading information for HSBI Common Stock and FBMS Common Stock and certain stock indices, as well as similar publicly available information for certain other companies, the securities of which are publicly traded; (viii) a comparison of certain financial and market information for HSBI and FBMS with similar financial institutions for which information is publicly available; (ix) the financial terms of certain recent business combinations in the bank and thrift industry (on a nationwide basis), to the extent publicly available; (x) the current market environment generally and the banking environment in particular; and (xi) such other information, financial studies, analyses and investigations and financial, economic and market criteria as we considered relevant. We also discussed with certain members of the senior management of HSBI and its representatives the business, financial condition, results of operations and prospects of HSBI and held similar discussions with certain members of the senior management of FBMS and its representatives regarding the business, financial condition, results of operations and prospects of FBMS.

TABLE OF CONTENTS

In performing our review, we have relied upon the accuracy and completeness of all of the financial and other information that was available to us from public sources, that was provided to us by HSBI, FBMS or their respective representatives, or that was otherwise reviewed by us and we have assumed such accuracy and completeness for purposes of rendering this opinion without any independent verification or investigation. We have further relied on the assurances of the respective senior managements of HSBI and FBMS that they are not aware of any facts or circumstances that would make any of such information inaccurate or misleading in any respect material to our analyses. We have not been asked to undertake, and have not undertaken, an independent verification of any such information and we do not assume any responsibility or liability for the accuracy or completeness thereof. We did not make an independent evaluation or perform an appraisal of the specific assets, the collateral securing assets or the liabilities (contingent or otherwise) of HSBI or FBMS, nor were we furnished with any such evaluations or appraisals. We render no opinion on, or evaluation of, the collectability of any assets or the future performance of any loans of HSBI or FBMS. We did not make an independent evaluation of the adequacy of the allowance for loan losses of HSBI or FBMS, or the combined entity after the Merger, and we have not reviewed any individual credit files relating to HSBI or FBMS. We have assumed, with your consent, that the respective allowances for loan losses for both HSBI and FBMS are adequate to cover such losses and will be adequate on a pro forma basis for the combined entity.

In preparing its analyses, Piper Sandler used internal net income estimates for HSBI for the years ending December 31, 2022 through December 31, 2024 with an annual net income growth rate for the years ending December 31, 2025 and December 31, 2026, as provided by and confirmed with the senior management of HSBI. In addition, Piper Sandler used publicly available mean analyst net income and dividend per share estimates for FBMS for the years ending December 31, 2022 and December 31, 2023, as provided by the senior management of FBMS, as well as a long-term annual earnings per share growth rate and estimated dividends per share for FBMS for the years ending December 31, 2024 through December 31, 2026, as provided by the senior management of FBMS. Piper Sandler also received and used in its pro forma analyses certain assumptions relating to transaction expenses, purchase accounting adjustments and cost savings, as well as an estimated net income growth rate for HSBI for the years ending December 31, 2025 and December 31, 2026, as provided by the senior management of FBMS. With respect to the foregoing information, the respective senior managements of HSBI and FBMS confirmed to us that such information reflected (or in the case of the publicly available analyst estimates referred to above, were consistent with) the best currently available estimates and judgements of senior management as to the future financial performance of HSBI and FBMS, respectively, and we assumed that the financial results reflected in such information would be achieved. We express no opinion as to such estimates or judgements, or the assumptions on which they are based. We have also assumed that there has been no material change in HSBI’s or FBMS’s assets, financial condition, results of operations, business or prospects since the date of the most recent financial statements made available to us. We have assumed in all respects material to our analyses that HSBI and FBMS will remain as going concerns for all periods relevant to our analyses.

We have also assumed, with your consent, that (i) each of the parties to the Agreement will comply in all material respects with all material terms and conditions of the Agreement and all related agreements required to effect the Merger, that all of the representations and warranties contained in such agreements are true and correct in all material respects, that each of the parties to such agreements will perform in all material respects all of the covenants and other obligations required to be performed by such party under such agreements and that the conditions precedent in such agreements are not and will not be waived, (ii) in the course of obtaining the necessary regulatory or third party approvals, consents and releases with respect to the Merger, no delay, limitation, restriction or condition will be imposed that would have an adverse effect on HSBI, FBMS, the Merger or any related transactions, and (iii) the Merger and any related transactions will be consummated in accordance with the terms of the Agreement without any waiver, modification or amendment of any material term, condition or agreement thereof and in compliance with all applicable laws and other requirements. Finally, with your consent, we have relied upon the advice that HSBI has received from its legal, accounting and tax advisors as to all legal, accounting and tax matters relating to the Merger and the other transactions contemplated by the Agreement. We express no opinion as to any such matters.

Our opinion is necessarily based on financial, regulatory, economic, market and other conditions as in effect on, and the information made available to us as of, the date hereof. Events occurring after the date

B-2

TABLE OF CONTENTS

hereof could materially affect this opinion. We have not undertaken to update, revise, reaffirm or withdraw this opinion or otherwise comment upon events occurring after the date hereof. We express no opinion as to the trading value of HSBI Common Stock or FBMS Common Stock at any time or what the value of FBMS Common Stock will be once it is actually received by the holders of HSBI Common Stock.

We have acted as HSBI’s financial advisor in connection with the Merger and will receive an advisory fee for our services, which fee is contingent upon consummation of the Merger. We will also receive a fee for rendering this opinion, which opinion fee will be credited in full towards the advisory fee which will become payable to Piper Sandler upon consummation of the Merger. HSBI has also agreed to indemnify us against certain claims and liabilities arising out of our engagement and to reimburse us for certain of our out-of-pocket expenses incurred in connection with our engagement. Piper Sandler has not provided any other investment banking services to HSBI in the two years preceding the date hereof, nor has Piper Sandler provided any investment banking services to FBMS in the two years preceding the date hereof. In the ordinary course of our business as a broker-dealer, we may purchase securities from and sell securities to HSBI and FBMS. We may also actively trade the equity and debt securities of HSBI and FBMS for our own account and for the accounts of our customers.

Our opinion is directed to the Board of Directors of HSBI in connection with its consideration of the Agreement and the Merger and does not constitute a recommendation to any shareholder of HSBI as to how any such shareholder should vote at any meeting of shareholders called to consider and vote upon the approval of the Agreement and the Merger. Our opinion is directed only as to the fairness, from a financial point of view, of the Merger Consideration to the holders of HSBI Common Stock and does not address the underlying business decision of HSBI to engage in the Merger, the form or structure of the Merger or any other transactions contemplated in the Agreement, the relative merits of the Merger as compared to any other alternative transactions or business strategies that might exist for HSBI or the effect of any other transaction in which HSBI might engage. We also do not express any opinion as to the fairness of the amount or nature of the compensation to be received in the Merger by any HSBI officer, director or employee, or class of such persons, if any, relative to the amount of compensation to be received by any other shareholder. This opinion has been approved by Piper Sandler’s fairness opinion committee. This opinion may not be reproduced without Piper Sandler’s prior written consent; provided, however, Piper Sandler will provide its consent for the opinion to be included in any regulatory filings, including the Proxy Statement-Prospectus and Registration Statement, to be filed with the SEC and mailed to shareholders in connection with the Merger.

Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Merger Consideration is fair to the holders of HSBI Common Stock from a financial point of view.

Very truly yours,

Members of the Board:

You have requested the opinion of Keefe, Bruyette & Woods, Inc. (“KBW” or “we”) as investment bankers as to the fairness, from a financial point of view, to The First Bancshares, Inc. (“FBMS”) of the Exchange Ratio (as defined below) in the proposed merger (the “Merger”) of Heritage Southeast Bancorporation, Inc. (“HSBI”) with and into FBMS, pursuant to the Agreement and Plan of Merger (the “Agreement”) to be entered into by and between FBMS and HSBI. Pursuant to the Agreement and subject to the terms, conditions and limitations set forth therein, at the Effective Time (as defined in the Agreement), automatically by virtue of the Merger and without any action on the part of FBMS, HSBI or any shareholder of HSBI, each share of common stock, $0.10 par value per share, of HSBI (“HSBI Common Stock”) (excluding Dissenting Shares and HSBI Cancelled Shares (each as defined in the Agreement)) issued and outstanding at the Effective Time will be converted into and exchanged for the right to receive 0.965 of a share of common stock, $1.00 par value per share, of FBMS (“FBMS Common Stock”). The ratio of 0.965 of a share of FBMS Common Stock for one share of HSBI Common Stock is referred to herein as the “Exchange Ratio.” The terms and conditions of the Merger are more fully set forth in the Agreement.

The Agreement further provides that, immediately following the Effective Time and sequentially but in effect simultaneously on the Closing Date (as defined in the Agreement), Heritage Southeast Bank, a wholly-owned subsidiary of HSBI, will be merged with and into The First Bank, a wholly-owned subsidiary of FBMS, pursuant to a separate merger agreement (such transaction, the “Bank Merger”).

KBW has acted as financial advisor to FBMS and not as an advisor to or agent of any other person. As part of our investment banking business, we are continually engaged in the valuation of bank and bank holding company securities in connection with acquisitions, negotiated underwritings, secondary distributions of listed and unlisted securities, private placements and valuations for various other purposes. As specialists in the securities of banking companies, we have experience in, and knowledge of, the valuation of banking enterprises. Further to an existing sales and trading relationship of KBW with FBMS, and otherwise in the ordinary course of KBW and its affiliates’ broker-dealer businesses, KBW and its affiliates may from time to time purchase securities from, and sell securities to, FBMS and HSBI. In addition, as market makers in securities, KBW and its affiliates may from time to time have a long or short position in, and buy or sell, debt or equity securities of FBMS or HSBI for its and their own respective accounts and for the accounts of its and their respective customers and clients. We have acted exclusively for the board of directors of FBMS (the “Board”) in rendering this opinion and will receive a fee from FBMS for our services. A portion of our fee is payable upon the rendering of this opinion, and a significant portion is contingent upon the successful completion of the Merger. In addition, FBMS has agreed to indemnify us for certain liabilities arising out of our engagement.

In addition to this present engagement, in the past two years KBW has provided investment banking and financial advisory services to FBMS and received compensation for such services. KBW acted as lead placement agent to FBMS in connection with its September 2020 offering of subordinated debt. KBW currently acts as broker for FBMS’ stock repurchase plan. In the past two years, KBW has not provided investment banking or financial advisory services to HSBI. We may in the future provide investment banking and financial advisory services to FBMS or HSBI and receive compensation for such services.

TABLE OF CONTENTS

In connection with this opinion, we have reviewed, analyzed and relied upon material bearing upon the financial and operating condition of FBMS and HSBI and bearing upon the Merger, including among other things, the following: (i) a draft of the Agreement dated July 26, 2022 (the most recent draft made available to us); (ii) the audited financial statements and the Annual Reports on Form 10-K for the three fiscal years ended December 31, 2021 of FBMS; (iii) the unaudited quarterly financial statements and Quarterly Report on Form 10-Q for the quarter ended March 31, 2022 of FBMS; (iv) certain preliminary and unaudited quarterly financial results for the quarter ended June 30, 2022 of FBMS (provided by FBMS); (v) the audited financial statements for the three fiscal years ended December 31, 2021 of HSBI; (vi) the unaudited quarterly financial statements for the quarter ended March 31, 2022 of HSBI; (vii) certain preliminary and unaudited quarterly financial results for the quarter ended June 30, 2022 of HSBI (provided by HSBI); (viii) certain regulatory filings of FBMS and HSBI and their respective subsidiaries, including, as applicable, the quarterly or semi-annual reports on Form FR Y-9C or Y-9SP and quarterly call reports filed with respect to each quarter during the three-year period ended December 31, 2021 and the quarter ended March 31, 2022; (ix) certain other interim reports and other communications of FBMS and HSBI to their respective shareholders; and (x) other financial information concerning the respective businesses and operations of FBMS and HSBI furnished to us by FBMS and HSBI or which we were otherwise directed to use for purposes of our analysis. Our consideration of financial information and other factors that we deemed appropriate under the circumstances or relevant to our analyses included, among others, the following: (i) the historical and current financial position and results of operations of FBMS and HSBI; (ii) the assets and liabilities of FBMS and HSBI; (iii) the nature and terms of certain other merger transactions and business combinations in the banking industry; (iv) a comparison of certain financial and stock market information of FBMS and HSBI with similar information for certain other companies, the securities of which are publicly traded; (v) financial and operating forecasts and projections of HSBI with respect to fiscal years 2022, 2023 and 2024 that were prepared by HSBI management, provided to and discussed with us by such management, and used and relied upon by us based on such discussions, at the direction of FBMS management and with the consent of the Board; (vi) publicly available consensus “street estimates” of FBMS, as well as assumed FBMS and HSBI long-term growth rates provided to us by FBMS management, all of which information was discussed with us by such management and used and relied upon by us at the direction of such management and with the consent of the Board; (vii) pro forma balance sheet and capital data of FBMS as of June 30, 2022, as adjusted for FBMS’s pending acquisition of Beach Bancorp, Inc., that was prepared by FBMS management, provided to and discussed with us by such management and used and relied upon by us at the direction of FBMS management and with the consent of the Board; and (viii) estimates regarding certain pro forma financial effects of the Merger on FBMS (including without limitation the cost savings and related expenses expected to result or be derived from the Merger) that were prepared by FBMS management, provided to and discussed with us by such management, and used and relied upon by us at the direction of such management and with the consent of the Board. We have also performed such other studies and analyses as we considered appropriate and have taken into account our assessment of general economic, market and financial conditions and our experience in other transactions, as well as our experience in securities valuation and knowledge of the banking industry generally. We have also participated in discussions held by the managements of FBMS and HSBI regarding the past and current business operations, regulatory relations, financial condition and future prospects of their respective companies and such other matters as we have deemed relevant to our inquiry.

In conducting our review and arriving at our opinion, we have relied upon and assumed the accuracy and completeness of all of the financial and other information that was provided to or discussed with us or that was publicly available and we have not independently verified the accuracy or completeness of any such information or assumed any responsibility or liability for such verification, accuracy or completeness. We have relied, with the consent of FBMS, upon the management of HSBI as to the reasonableness and achievability of the financial and operating forecasts and projections of HSBI with respect to fiscal years 2022, 2023 and 2024 as referred to above (and the assumptions and bases therefor), and we have assumed that such forecasts and projections have been reasonably prepared and represent the best currently available estimates and judgments of such management and that such forecasts and projections will be realized in the amounts and in the time periods currently estimated by such management. We have further relied upon the management of FBMS as to the reasonableness and achievability of the publicly available consensus “street estimates” of FBMS, the assumed FBMS and HSBI long-term growth rates, and the estimates regarding certain pro forma financial effects of the Merger on FBMS (including, without limitation, the cost

C-2

TABLE OF CONTENTS

savings and related expenses expected to result or be derived from the Merger), all as referred to above (and the assumptions and bases for all such information), and we have assumed that all such information has been reasonably prepared and represents, or in the case of the publicly available consensus “street estimates” of FBMS referred to above that such estimates are consistent with, the best currently available estimates and judgments of FBMS management and that the forecasts, projections and estimates reflected in such information will be realized in the amounts and in the time periods currently estimated.

It is understood that the portion of the foregoing financial information of FBMS and HSBI that was provided to us was not prepared with the expectation of public disclosure and that all of the foregoing financial information, including the publicly available consensus “street estimates” of FBMS referred to above, is based on numerous variables and assumptions that are inherently uncertain (including, without limitation, factors related to general economic and competitive conditions, and in particular, assumptions regarding the ongoing COVID-19 pandemic) and, accordingly, actual results could vary significantly from those set forth in such information. We have assumed, based on discussions with the respective managements of FBMS and HSBI and with the consent of the Board, that all such information provides a reasonable basis upon which we can form our opinion, and we express no view as to any such information or the assumptions or bases therefor. Among other things, such information has assumed that the ongoing COVID-19 pandemic could have an adverse impact, which has been assumed to be limited, on FBMS and HSBI. We have relied on all such information without independent verification or analysis and do not in any respect assume any responsibility or liability for the accuracy or completeness thereof.

We also have assumed that there have been no material changes in the assets, liabilities, financial condition, results of operations, business or prospects of either FBMS or HSBI since the date of the last financial statements of each such entity that were made available to us. We are not experts in the independent verification of the adequacy of allowances for loan and lease losses and we have assumed, without independent verification and with your consent, that the aggregate allowances for loan and lease losses for each of FBMS and HSBI are adequate to cover such losses. In rendering our opinion, we have not made or obtained any evaluations or appraisals or physical inspection of the property, assets or liabilities (contingent or otherwise) of FBMS or HSBI, the collateral securing any of such assets or liabilities, or the collectability of any such assets, nor have we examined any individual loan or credit files, nor did we evaluate the solvency, financial capability or fair value of FBMS or HSBI under any state or federal laws, including those relating to bankruptcy, insolvency or other matters. Estimates of values of companies and assets do not purport to be appraisals or necessarily reflect the prices at which companies or assets may actually be sold. Such estimates are inherently subject to uncertainty and should not be taken as our view of the actual value of any companies or assets.

We have assumed, in all respects material to our analyses, the following: (i) that the Merger and any related transactions (including, without limitation, the Bank Merger) will be completed substantially in accordance with the terms set forth in the Agreement (the final terms of which we have assumed will not differ in any respect material to our analyses from the draft version reviewed by us and referred to above) with no adjustments to the Exchange Ratio and with no other consideration or payments in respect of HSBI Common Stock; (ii) that the representations and warranties of each party in the Agreement and in all related documents and instruments referred to in the Agreement are true and correct; (iii) that each party to the Agreement and all related documents will perform all of the covenants and agreements required to be performed by such party under such documents; (iv) that there are no factors that would delay or subject to any adverse conditions, any necessary regulatory or governmental approval for the Merger or any related transactions and that all conditions to the completion of the Merger and any related transactions will be satisfied without any waivers or modifications to the Agreement or any of the related documents; and (v) that in the course of obtaining the necessary regulatory, contractual, or other consents or approvals for the Merger and any related transactions, no restrictions, including any divestiture requirements, termination or other payments or amendments or modifications, will be imposed that will have a material adverse effect on the future results of operations or financial condition of FBMS, HSBI or the pro forma entity or the contemplated benefits of the Merger, including without limitation the cost savings and related expenses expected to result or be derived from the Merger. We have assumed that the Merger will be consummated in a manner that complies with the applicable provisions of the Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as amended, and all other applicable federal and state statutes, rules and regulations. We have further been advised by representatives of FBMS that FBMS has relied upon advice

from its advisors (other than KBW) or other appropriate sources as to all legal, financial reporting, tax, accounting and regulatory matters with respect to FBMS, HSBI, the Merger and any related transaction, and the Agreement. KBW has not provided advice with respect to any such matters.

This opinion addresses only the fairness, from a financial point of view, as of the date hereof, of the Exchange Ratio in the Merger to FBMS. We express no view or opinion as to any other terms or aspects of the Merger or any term or aspect of any related transaction (including the Bank Merger), including without limitation, the form or structure of the Merger or any such related transaction, any consequences of the Merger or any such related transaction to FBMS, its shareholders, creditors or otherwise, or any terms, aspects, merits or implications of any employment, voting, support, lock-up, shareholder or other agreements, arrangements or understandings contemplated or entered into in connection with the Merger, any such related transaction, or otherwise. Our opinion is necessarily based upon conditions as they exist and can be evaluated on the date hereof and the information made available to us through the date hereof. There is currently significant volatility in the stock and other financial markets arising from global tensions, economic uncertainty and the effects of the COVID-19 pandemic, including the effect of evolving governmental interventions and non-interventions. It is understood that subsequent developments may affect the conclusion reached in this opinion and that KBW does not have an obligation to update, revise or reaffirm this opinion. Our opinion does not address, and we express no view or opinion with respect to, (i) the underlying business decision of FBMS to engage in the Merger or enter into the Agreement, (ii) the relative merits of the Merger as compared to any strategic alternatives that are, have been or may be available to or contemplated by FBMS or the Board, (iii) any business, operational or other plans with respect to HSBI or the pro forma entity that may be currently contemplated by FBMS or the Board or that may be implemented by FBMS or the Board subsequent to the closing of the Merger, (iv) the fairness of the amount or nature of any compensation to any of FBMS’s officers, directors or employees, or any class of such persons, relative to any compensation to the holders of FBMS Common Stock or relative to the Exchange Ratio, (v) the effect of the Merger or any related transaction on, or the fairness of the consideration to be received by, holders of any class of securities of FBMS, HSBI or any other party to any transaction contemplated by the Agreement, (vi) any adjustment (as provided in the Agreement) to the Exchange Ratio assumed to be paid in the Merger for purposes of our opinion; (vii) the actual value of FBMS Common Stock to be issued in connection with the Merger, (viii) the prices, trading range or volume at which FBMS Common Stock or HSBI Common Stock will trade following the public announcement of the Merger or the prices, trading range or volume at which FBMS Common Stock will trade following the consummation of the Merger, (ix) any advice or opinions provided by any other advisor to any of the parties to the Merger or any other transaction contemplated by the Agreement, or (x) any legal, regulatory, accounting, tax or similar matters relating to FBMS, HSBI, any of their respective shareholders, or relating to or arising out of or as a consequence of the Merger or any other related transaction, including whether or not the Merger will qualify as a tax-free reorganization for United States federal income tax purposes.

This opinion is for the information of, and is directed to, the Board (in its capacity as such) in connection with its consideration of the financial terms of the Merger. This opinion does not constitute a recommendation to the Board as to how it should vote on the Merger or to any holder of FBMS Common Stock or any shareholder of any other entity as to how to vote in connection with the Merger or any other matter, nor does it constitute a recommendation as to whether or not any such shareholder should enter into a voting, shareholders’, affiliates’ or other agreement with respect to the Merger or exercise any dissenters’ or appraisal rights that may be available to such shareholder.

This opinion has been reviewed and approved by our Fairness Opinion Committee in conformity with our policies and procedures established under the requirements of Rule 5150 of the Financial Industry Regulatory Authority.

Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Exchange Ratio in the Merger is fair, from a financial point of view, to FBMS.

Very truly yours,

Keefe, Bruyette & Woods, Inc.

Members of the Board:

We understand that The First Bancshares, Inc. (“FBMS”) and The First Bank, a wholly owned subsidiary of FBMS, propose to enter into an Agreement and Plan of Merger (the “Agreement”) with Heritage Southeast Bancorporation, Inc. (“HSBI”), and its wholly-owned subsidiary Heritage Southeast Bank pursuant to which, among other things, HSBI will merge with and into FBMS (the “Merger”) and each outstanding share of HSBI Stock (excluding Dissenting Shares and HSBI Cancelled Shares) issued and outstanding at the Effective Time will be converted into the right to receive 0.965 shares of FBMS Common Stock (the “Merger Consideration”). The terms and conditions of the Merger are more fully set forth in the Agreement.

Capitalized terms used herein without definition have the respective meanings ascribed to them in the Agreement.

You have requested our opinion as to the fairness, from a financial point of view, to FBMS of the Merger Consideration in the proposed Merger.

In connection with preparing our opinion, we have reviewed, among other things:

(i)

(ix)

(x)

the expected relative contributions of FBMS and HSBI to the combined company;

(xi)

the net present value of FBMS, HSBI and the combined entity with consideration of projected financial results; and

(xii)

other such financial studies, analyses, investigations, economic and market information that we considered relevant including discussions with management and other representatives and advisors of FBMS and HSBI concerning the business, financial condition, results of operations and prospects of HSBI and FBMS.

In arriving at our opinion, we have, with your consent, assumed and relied upon the accuracy and completeness of all information that was publicly available or supplied or otherwise made available to, discussed with or reviewed by or for us. We have not independently verified (nor have we assumed responsibility for independently verifying) such information or its accuracy or completeness. We have relied on the assurances of management of FBMS that they are not aware of any facts or circumstances that would make any of such information, projections or estimates inaccurate or misleading. We have not undertaken or been provided with any independent evaluation or appraisal of any of the assets or liabilities (contingent or otherwise) of HSBI or FBMS. In addition, we have not assumed any obligation to conduct, nor have we conducted, any physical inspection of the properties or facilities of HSBI or FBMS, and have not been provided with any reports of such physical inspections. We have assumed that there has been no material change in HSBI’s or FBMS’s business, assets, financial condition, results of operations, cash flows or prospects since the date of the most recent financial statements provided to us.

With respect to the financial projections and estimates (including information relating to the amounts and timing of the merger costs, cost savings, and revenue enhancements) provided to or otherwise reviewed by or for or discussed with us, we have been advised by management of FBMS, and have assumed with your consent, that such projections and estimates were reasonably prepared on bases reflecting the best currently available estimates and good faith judgments of management of FBMS as to the future financial performance of HSBI and FBMS and the other matters covered thereby, and that the financial results reflected in such projections and estimates will be realized in the amounts and at the times projected. We assume no responsibility for and express no opinion as to these projections and estimates or the assumptions on which they were based. We have relied on the assurances of management of FBMS that they are not aware of any facts or circumstances that would make any of such information, projections or estimates inaccurate or misleading.

We are not experts in the evaluation of loan and lease portfolios, classified loans or other real estate owned or in assessing the adequacy of the allowance for loan losses with respect thereto, and we did not make an independent evaluation or appraisal thereof, or of any other specific assets, the collateral securing assets or the liabilities (contingent or otherwise) of HSBI or FBMS or any of their respective subsidiaries. We have not reviewed any individual loan or credit files relating to HSBI or FBMS. We have assumed, with your consent, that the respective allowances for loan and lease losses for both HSBI and FBMS are adequate to cover such losses and will be adequate on a pro forma basis for the combined entity. We did not make an independent evaluation of the quality of HSBI’s or FBMS’s deposit base, nor have we independently evaluated potential deposit concentrations or the deposit composition of HSBI or FBMS. We did not make an independent evaluation of the quality of HSBI’s or FBMS’s investment securities portfolio, nor have we independently evaluated potential concentrations in the investment securities portfolio of HSBI or FBMS.

We have assumed that all of the representations and warranties contained in the Agreement and all related agreements are true and correct in all respects material to our analysis, 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 covenant thereof the effect of which would be in any respect material to our analysis. We also have assumed that all material governmental, regulatory or other consents, approvals, and waivers necessary for the consummation of the Merger will be obtained without any material adverse effect on

D-2

TABLE OF CONTENTS

HSBI or FBMS or the contemplated benefits of the Merger. Further, we have assumed that the executed Agreement will not differ in any material respect from the draft Agreement, dated July 22, 2022, reviewed by us.

We have assumed in all respects material to our analysis that HSBI and FBMS will remain as a going concern for all periods relevant to our analysis. We express no opinion regarding the liquidation value of HSBI and FBMS or any other entity.

Our opinion is limited to the fairness, from a financial point of view, to FBMS of the Merger Consideration to be paid in the proposed Merger. We do not express any view on, and our opinion does not address, any other term or aspect of the Agreement or Merger (including, without limitation, the form or structure of the Merger) or any term or aspect of any other agreement or instrument contemplated by the Agreement or entered into in connection with the Merger, or as to the underlying business decision by FBMS to engage in the Merger. Furthermore, we express no opinion with respect to the amount or nature of any compensation to any officers, directors or employees of HSBI or FBMS, or any class of such persons, relative to the Merger Consideration to be paid to the holders of HSBI Stock in the Merger, or with respect to the fairness of any such compensation to FBMS.

We express no view as to, and our opinion does not address, the relative merits of the Merger as compared to any alternative business transactions or strategies, or whether such alternative transactions or strategies could be achieved or are available. In addition, our opinion does not address any legal, regulatory, tax or accounting matters, as to which we understand that FBMS obtained such advice as it deemed necessary from qualified professionals.

We express no opinion as to the actual value of FBMS Common Stock when issued in the Merger or the prices at which FBMS Common Stock will trade following announcement of the Merger or at any future time.

We have not evaluated the solvency or fair value of HSBI or FBMS under any state, federal or other laws relating to bankruptcy, insolvency or similar matters. This opinion is not a solvency opinion and does not in any way address the solvency or financial condition of HSBI or FBMS. We are not expressing any opinion as to the impact of the Merger on the solvency or viability of HSBI or FBMS or the ability of HSBI or FBMS to pay their respective obligations when they come due.

We will receive a fee for our services, which is payable upon the rendering of this opinion. In addition, FBMS has agreed to reimburse our reasonable expenses and indemnify us against certain liabilities arising out of our engagement.

During the two years preceding the date of this letter, neither we nor our affiliates have had any other material financial advisory or other material commercial or investment banking relationships with HSBI or FBMS.

In the ordinary course of our business, D.A. Davidson & Co. and its affiliates may actively trade or hold securities of HSBI or FBMS for our own accounts or for the accounts of our customers and, accordingly, may at any time hold long or short positions in such securities. We may seek to provide investment banking or other financial services to HSBI or FBMS in the future for which we would expect to receive compensation.

This fairness opinion was reviewed and approved by a D.A. Davidson & Co. Fairness Opinion Committee.

This opinion is solely for the information of the Board of Directors of FBMS (solely in its capacity as such) in connection with its consideration of the Merger and shall not be relied upon by any other party or disclosed, referred to, published or otherwise used (in whole or in part), nor shall any public references to us be made, without our prior written consent.

Our opinion is necessarily based on economic, market and other conditions as in effect on, and the information made available to us as of, the date hereof. Events occurring after the date hereof may affect this opinion and the assumptions used in preparing it, and we do not assume any obligation to update, revise or reaffirm this opinion.

(1) Against the corporation and in favor of any or all dissenters if the court finds the corporation did not substantially comply with the requirements of Code Sections 14-2-1320 through 14-2-1327; or

(2) Against either the corporation or a dissenter, in favor of any other party, if the court finds that the party against whom the fees and expenses are assessed acted arbitrarily, vexatiously, or not in good faith with respect to the rights provided by this article.

(c) If the court finds that the services of attorneys for any dissenter were of substantial benefit to other dissenters similarly situated, and that the fees for those services should not be assessed against the corporation, the court may award to these attorneys reasonable fees to be paid out of the amounts awarded the dissenters who were benefited.

Ga. Code Ann., § 14-2-1332

§ 14-2-1332. Limitation of actions

No action by any dissenter to enforce dissenters’ rights shall be brought more than three years after the corporate action was taken, regardless of whether notice of the corporate action and of the right to dissent was given by the corporation in compliance with the provisions of Code Section 14-2-1320 and Code Section 14-2-1322.

INDEPENDENT AUDITOR’S REPORT

To the Board of Directors and Shareholders
Heritage Southeast Bancorporation Inc. and Subsidiary
Jonesboro, Georgia

Opinions on the Financial Statements and Internal Control Over Financial Reporting

We have audited the consolidated financial statements (the “financial statements”) of Heritage Southeast Bancorporation Inc. and Subsidiary (the “Company”), which comprise the consolidated balance sheets as of December 31, 2021 and 2020, and the related consolidated statements of income, comprehensive income, shareholders’ equity, and cash flows for the years then ended, and the related notes to the consolidated financial statements.

In our opinion, the accompanying consolidated financial statements referred to above present fairly, in all material respects, the financial position of Heritage Southeast Bancorporation Inc. and Subsidiary as of December 31, 2021 and 2020, and the results of its operations and its cashflows for the years then ended in accordance with accounting principles generally accepted in the United States of America (“GAAP”).

We also have audited the Company’s internal control over financial reporting, including controls over the preparation of regulatory financial statements in accordance with instructions to the Federal Financial Institutions Examination Council Consolidated Reports of Condition and Income (“Call Report”), as of December 31, 2021, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in 2013. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control — Integrated Framework issued by COSO in 2013.

Basis for Opinion

We conducted our audits in accordance with auditing standards generally accepted in the United States of America (“GAAS”). Our responsibilities under those standards are further described in the Auditor’s Responsibilities for the Audit of the Financial Statements section of our report. We are required to be independent of Heritage Southeast Bancorporation Inc. and Subsidiary and to meet our other ethical responsibilities, in accordance with the relevant ethical requirements relating to our audits. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Responsibilities of Management for the Financial Statements and Internal Control Over Financial Reporting

Management is responsible for the preparation and fair presentation of the financial statements in accordance with accounting principles generally accepted in the United States of America, and for the design, implementation, and maintenance of effective internal control over financial reporting relevant to the preparation and fair presentation of financial statements that are free from material misstatement, whether due to fraud or error. Management is also responsible for its assessment about the effectiveness of internal control over financial reporting, included in the accompanying Management Report.

In preparing the financial statements, management is required to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about Heritage Southeast Bancorporation Inc. and Subsidiary’s ability to continue as a going concern for one year after the date the financial statements are available to be issued.

Auditor’s Responsibilities for the Audits of the Financial Statements and Internal Control Over Financial Reporting

Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due to fraud or error, and about whether effective internal

F-2

TABLE OF CONTENTS

control over financial reporting was maintained in all material respects, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance but is not absolute assurance and therefore is not a guarantee that an audit of financial statements or an audit of internal control over financial reporting conducted in accordance with GAAS will always detect a material misstatement or a material weakness when it exists. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control. Misstatements are considered material if there is a substantial likelihood that, individually or in the aggregate, they would influence the judgment made by a reasonable user based on the financial statements.

In performing an audit of financial statements or an audit of internal control over financial reporting in accordance with GAAS, we:

•

Exercise professional judgment and maintain professional skepticism throughout the audits.

•

Identify and assess the risks of material misstatement of the financial statements, whether due to fraud or error, and design and perform audit procedures responsive to those risks. Such procedures include examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements.

•

Obtain an understanding of internal control relevant to the financial statement audit in order to design audit procedures that are appropriate in the circumstances.

•

Obtain an understanding of internal control over financial reporting relevant to the audit of internal control over financial reporting, assess the risks that a material weakness exists, and test and evaluate the design and operating effectiveness of internal control over financial reporting based on the assessed risk.

•

Evaluate the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluate the overall presentation of the financial statements.

•

Conclude whether, in our judgment, there are conditions or events, considered in the aggregate, that raise substantial doubt about Heritage Southeast Bancorporation Inc. and Subsidiary’s ability to continue as a going concern for a reasonable period of time.

We are required to communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit, significant audit findings, and certain internal control — related matters that we identified during the financial statement audit.

Definition and Inherent Limitations of Internal Control over Financial Reporting

An entity’s internal control over financial reporting is a process effected by those charged with governance, management, and other personnel, designed to provide reasonable assurance regarding the preparation of reliable financial statements in accordance with GAAP. Because management’s assessment and our audit were conducted to meet the reporting requirements of Section 112 of the Federal Deposit Insurance Corporation Improvement Act (FDICIA), our audit of the Company’s internal control over financial reporting included controls over the preparation of financial statements in accordance with GAAP and with Call Report instructions.

An entity’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the entity; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures of the entity are being made only in accordance with authorizations of management and those charged with governance; and (3) provide reasonable assurance regarding prevention or timely detection and correction of unauthorized acquisition, use, or disposition of the entity’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect and correct misstatements. Also, projections of any evaluation of effectiveness to future periods are subject

Summary of Significant Accounting Policies

Organization

Heritage Southeast Bancorporation, Inc. (“Heritage” or the “Company”) received regulatory approval to operate as a bank holding company on March 23, 1995. Heritage is primarily regulated by the Board of Governors of the Federal Reserve System (the “FRB”) and serves as the one-bank holding company for Heritage Southeast Bank (the “Bank”). The Company’s name was changed from CCF Holding Company to Heritage Southeast Bancorporation, Inc. effective September 1, 2019. On September 1, 2019, the Company acquired Heritage Bancorporation, Inc. and Providence Bank by exchanging shares for all the outstanding stock of each entity.

The Bank commenced operations in 1955 upon receipt of its banking charter from the Georgia Department of Banking and Finance (the “GDBF”). The Bank is primarily regulated by the GDBF and the Federal Deposit Insurance Corporation (the “FDIC”). The Bank, whose main office is in Jonesboro, Georgia, provides a full range of commercial and consumer banking services primarily in North and South metro Atlanta, Georgia along with southeastern Georgia and northeastern Florida.

On March 31, 2021, the Company and the Bank entered into a Purchase and Assumption Agreement (the “Purchase Agreement”) with VyStar Credit Union (“VyStar”), a Florida Credit Union, pursuant to which VyStar will acquire substantially all of the assets of the Company and the Bank and assume substantially all of the liabilities of the Company and the Bank (the “Acquisition”). Following the Acquisition, the Company and the Bank after all obligations are settled, will distribute all remaining assets to the Company’s shareholders. The Acquisition was approved by the Company’s shareholders on July 12, 2021. The Acquisition is contingent upon receipt of regulatory approval from the National Credit Union Administration, the FDIC, the Florida Office of Financial Regulation and the GDBF, among other closing conditions. Subject to receipt of the required approvals, the Acquisition is expected to close in the second quarter of 2022.

Principles of Consolidation

The consolidated financial statements include the financial statements of Heritage and its wholly owned subsidiary. All significant intercompany balances and transactions have been eliminated in consolidation.

Basis of Presentation

The accounting principles followed by the Company, and the methods of applying these principles conform with accounting principles generally accepted in the United State of America (“GAAP”) and with general practices in the banking industry. In preparing financial statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ significantly from these estimates. Material estimates common to the banking industry that are particularly susceptible to significant change in the near term include, but are not limited to, the determination of the allowance for loan losses, valuation of other real estate owned, valuation of deferred tax assets and the fair value of purchase accounting adjustments.

Cash and Cash Equivalents

Cash equivalents include amounts due from banks, interest-bearing deposits in banks and federal funds sold. Federal funds are generally sold for one-day periods and interest-bearing deposits in banks are available on demand. Effective March 12, 2020, the Federal Reserve’s board of directors approved reducing the required reserve requirements ratio to zero percent, effectively eliminating the requirement to maintain reserve

Summary of Significant Accounting Policies (continued)

balances in cash or on deposit with the Federal Reserve Bank. This reduction in the required reserves does not have a defined timeframe and may be revised by the Federal Reserve’s board in the future.

Investment Securities

The Company classifies its investment securities as held to maturity or available for sale. Held to maturity securities are those securities for which the Company has the ability and intent to hold until maturity. All other securities are classified as available for sale. At December 31, 2021 and 2020, all investment securities were classified as available for sale.

Held to maturity securities are recorded at cost, adjusted for amortization or accretion of premiums or discounts. Available for sale securities are recorded at fair value with unrealized holding gains and losses, net of the related tax effect, excluded from operations and reported in other comprehensive income as a separate component of shareholders’ equity until realized.

Management evaluates investment securities for other than temporary impairment on a quarterly basis. A decline in the fair value of securities below cost that is deemed other than temporary is charged to earnings for the decline in value deemed to be credit-related and a new cost basis for the security is established. The decline in value attributed to non-credit-related factors is recognized in other comprehensive income. Premiums and discounts are amortized or accreted over the life of the related security as an adjustment to the yield. Realized gains and losses for securities are included in operations and derived using the specific identification method for determining the cost of the securities sold.

Other Investments

Other investments consist of Federal Home Loan Bank (“FHLB”) stock that does not have a readily determinable fair value. The FHLB stock is included in other investments at its original cost basis. FHLB stock is evaluated for impairment on an annual basis.

Originated Loans

Loans that management has the intent and ability to hold for the foreseeable future or until maturity are reported at the principal amount outstanding, net of charge-offs and net of any deferred loan fees and costs. Interest on loans is primarily calculated by using the simple interest method on daily balances of the principal amount outstanding. Loan origination fees and certain direct origination costs are capitalized and amortized over the life of the related loan.

Impaired loans, in relationships exceeding $250,000, are measured based on the present value of expected future cash flows, discounted at the loan’s effective interest rate, at the loan’s observable market price, or the fair value of the collateral, if the loan is collateral dependent. Impaired loans in relationships less than $250,000 are collectively evaluated. A loan is impaired when, based on current information and events, it is probable that all amounts due according to the contractual terms of the loan will not be collected.

Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due. Loans are placed on non-accrual status when, in management’s opinion, the borrower may be unable to meet payment obligations as they become due, as well as when required by regulatory provisions. Loans may be placed on non-accrual status regardless of whether or not such loans are considered past due. Accrual of interest is discontinued on a loan when management believes, after considering economic conditions and collection efforts that the borrower’s financial condition is such that collection of interest is doubtful. Interest previously accrued but not collected is reversed against current period earnings. Interest income is subsequently recognized only to the extent cash payments are received in excess of principal due. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.

Allowance for Loan Losses

The allowance for loan losses reflects management’s assessment of the risks associated with extending credit and its evaluation of the quality of the loan portfolio. The Company periodically analyzes the loan portfolio in an effort to review asset quality and to establish an allowance for loan losses that management believes will be adequate in light of anticipated risks and loan losses. In assessing the adequacy of the allowance, size, quality and risk of loans in the portfolio are reviewed. Other factors considered are:

•

the Company’s loan loss experience;

•

the amount of past due and non-performing loans;

•

specific known risks;

•

the status and amount of other past due and non-performing assets;

•

underlying estimated values of collateral securing loans;

•

current and anticipated economic conditions; and,

•

other factors which management believes affect the allowance for potential credit losses.

The allowance for loan losses is comprised of specific reserves and general reserve components. After a loan has been identified as impaired, management measures impairment based on the present value of expected future cash flows or the fair value of the collateral, if the loan is collateral dependent.

The Company’s impaired loans include troubled debt restructurings. When the measure of the impaired loan, as determined by either the is less than the recorded investment in the loan, the amount of the impairment is recorded as a specific reserve or the loan is charged down. These specific reserves are determined on an individual loan basis based on management’s current evaluation of the Company’s loss exposure for each credit. Loans for which specific reserves are provided are excluded from the general allowance calculations described below.

The general allowance reflects reserves established under GAAP for collective loan impairment. These reserves are based upon historical net charge-offs using the last two years’ experience. This charge-off experience is adjusted to reflect the effects of current conditions. The Company considers information derived from its loan risk ratings and external data related to industry and general economic trends in establishing reserves.

Management considers the allowance for loan losses adequate to cover the estimated losses inherent in the Company’s loan portfolio as of the date of the financial statements. Management believes it has established the allowance in accordance with GAAP and in consideration of the current economic environment. Although management uses the best information available to make evaluations, significant further additions to the allowance may be necessary based on changes in economic and other conditions, thus adversely affecting the operating results of the Company.

There were no significant changes in the estimation methods or fundamental assumptions used in the evaluation of the allowance for loan losses for the year ended December 31, 2021, compared to the year ended December 31, 2020. Such revisions, estimates and assumptions are made in any period in which the supporting factors indicate that loss levels may vary from the previous estimates.

Additionally, various regulatory agencies, as an integral part of their examination process, periodically review the Company’s allowance for loan losses. Such agencies may require adjustments to the allowance based on their judgments of information available to them at the time of their examinations. Also, an independent loan review process further assists with evaluating credit quality and assessing potential performance issues.

Summary of Significant Accounting Policies (continued)

For purposes of determining the allowance for loan losses, Management segments the loan portfolio into broad categories with similar risk elements. Those categories and their specific risks are described below:

Construction and land development — Included in this category is both residential and commercial construction. Risks associated with this category are costs overruns, changes in market demand for property, inadequate long-term financing arrangements and declines in real estate values.

Single-family residential — This loan category includes residential mortgages and home equity lines of credit and these loans are susceptible to weakening general economic conditions, increases in unemployment rates and declining real estate values.

Real Estate (Commercial) — This category includes owner occupied and income producing real estate and risks include the failure of the owner’s business, general economic conditions, declines in real value, declines in occupancy rates, and lack of suitable alternative use for the property.

Multifamily — This category can have risks associated with declines in general economic conditions, declines in real estate values and declines in occupancy rates.

Commercial (not real estate) — Risks to this category include customer or industry concentrations and the inability to monitor the condition of the collateral which often consists of inventory, accounts receivable and other non-real estate assets. Equipment and inventory obsolescence can also pose a risk. Decline in general economic conditions and other events can cause cash flows to fall to levels insufficient to service debt.

Consumer — Common risks include regulatory risks, unemployment and changes in local economic conditions as well as the inability to monitor collateral consisting of personal property.

Loan Commitments and Related Financial Instruments

Financial instruments include off-balance sheet credit instruments, such as commercial letters of credit that are issued to meet customer financing needs and commitments to make loans other than those to residential mortgage loan customers. The face amount for these items represents the exposure to loss before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded.

Business Combinations, Accounting for Credit-Deteriorated Purchased Loans and Related Assets

Business combinations are accounted for by applying the acquisition method in accordance with ASC 805, “Business Combinations.” Under the acquisition method, identifiable assets acquired and liabilities assumed and any non-controlling interest in the acquiree at the acquisition date are measured at their fair values as of that date and are recognized separately from goodwill. Results of operations of the acquired entities are included in the Consolidated Statements of Income from the date of acquisition. Acquisition costs incurred by the Company are expensed as incurred.

Loans purchased in business combinations with evidence of credit deteriorations since origination and for which it is probable that all contractually required payments will not be collected are considered to be credit-impaired. Purchased credit impaired loans are accounted for in accordance with ASC 310-30, “Loans and Debt Securities Acquired with Deteriorated Credit Quality” (“ASC 310-30”), and initially measured at fair value, which includes estimated future credit losses expected to be incurred over the life of the loans. Increase in expected cash flows to be collected on these loans are recognized as an adjustment of the loan’s yield over its remaining life, while decreases in expected cash flows are recognized immediately as impairment through a provision for loan losses.

Summary of Significant Accounting Policies (continued)

Premises and Equipment

Premises and equipment are recorded at cost less accumulated depreciation. Depreciation is computed primarily using the straight-line method over the estimated useful lives of the related assets. When assets are retired or otherwise disposed, the cost and related accumulated depreciation are removed from the accounts, and any gain or loss is reflected in earnings for the period. The cost of maintenance and repairs that do not improve or extend the useful life of the respective asset are charged to earnings as incurred, whereas significant renewals and improvements are capitalized. The range of estimated useful lives for buildings and improvements is 15 to 40 years and 3 to 10 years for furniture and equipment.

Other Real Estate Owned

Other real estate owned includes all real property received in full or partial satisfaction of a loan. Other real estate owned is recorded at the lower of the related loan’s cost basis or its fair value less estimated selling costs which establishes a cost basis in the property at the time of foreclosure. For properties acquired through foreclosure or deed in lieu, fair values are based on independent appraisals. Any writedown at the time of foreclosure is charged to the allowance for loan losses. Costs of improvements are capitalized, whereas costs relating to holding other real estate owned and subsequent adjustments to the value are expensed.

Transfers of Financial Assets

A transfer of financial assets is accounted for as a sale if the transferee is not an entity that the Bank must consolidate and provided the Company does not have any form of continuing involvement, rights or obligations associated with the transferred financial assets. If the Company does have a form of continuing involvement, rights or obligations with the transferred financial assets, the transfer is accounted for as a sale when, (1) the assets have been isolated from the Company — put presumptively beyond the reach of the transferor and its creditors, even in bankruptcy or other receivership, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity or the ability to unilaterally cause the holder to return specific assets.

Cash Surrender Value of Bank Owned Life Insurance

The Company has purchased life insurance policies on certain key executives and members of management. Bank owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value or return of premiums, depending on the contract, adjusted for other changes or other amounts due that are probable at settlement.

Goodwill

Goodwill represents the cost of acquired companies in excess of the fair value of the net assets acquired. Goodwill is not amortized over a useful life. Instead, it is reviewed for impairment annually, or more frequently if deemed necessary. No impairment was recognized for the years ended December 31, 2021 and 2020. The goodwill is not deductible for income tax purposes.

Core Deposit Intangible

The core deposit intangible is established in the allocation of purchase price to the fair value of identifiable net assets acquired. The Company recorded core deposit intangible assets in connection of the acquisitions of Heritage Bancorporation, Inc. and Providence Bank of $9.2 million and $317 thousand,

respectively. The core deposit intangible is amortized on a straight-line basis over the estimated period of benefit of ten years. Amortization expense was approximately $950 thousand for the years ended December 31, 2021 and 2020.

Securities Sold Under Agreements to Repurchase

Securities sold under agreements to repurchase (“repurchase agreements”) represent funds received from customers, generally on an overnight or continuous basis, which are collateralized by investment securities owned by the Company. The securities used as collateral consist primarily of U.S. Government obligations, residential mortgage-backed securities and collateralized mortgage obligations and all are maintained by the Company’s safekeeping agents. These securities are reviewed on a daily basis, and the Company may be required to provide additional collateral due to changes in the fair market value of these securities. The terms of the Company’s repurchase agreements are continuous but may be cancelled at any time by the Company or the customer.

Income Taxes

Deferred tax assets and liabilities are recorded for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Future tax benefits are recognized to the extent that realization of such benefits is more likely than not. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which the assets and liabilities are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income taxes during the period that includes the enactment date.

In the event the future tax consequences of differences between the financial reporting bases and the tax bases of the Company’s assets and liabilities results in deferred tax assets, an evaluation of the probability of being able to realize the future benefits indicated by such asset is required. A valuation allowance is provided for the portion of the deferred tax asset when it is more likely than not that some or all of the deferred tax asset will not be realized. In assessing the likelihood of the realization of deferred tax assets, management considers the scheduled reversals of deferred tax liabilities, projected future taxable earnings and tax planning strategies. Deferred tax valuation allowance assessments require significant amounts of judgment. GAAP requires the more likely than not criteria (a likelihood of 50% or more) to be used; however, the likelihood is not possible to be expressed in purely mathematical terms. Highly subjective information about future events heavily factor into the conclusion as to whether the more likely than not criteria can be achieved.

The Company currently evaluates uncertainty in income tax positions. GAAP requires that a loss contingency reserve be accrued if it is probable that the tax position will be challenged, it is probable that the future resolution of the challenge will confirm that a loss has been incurred, and the amount of such loss can be reasonably estimated.

Loss Contingencies

Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe there are such matters that will have a material effect on the financial statements.

Stock-Based Compensation

The Company uses the fair value method for recognizing expense for stock-based compensation based on the fair value of option and restricted stock awards at the date of grant, recognized over the vesting period.

Comprehensive Income

GAAP normally requires that recognized revenues, expenses, gains and losses be included in net earnings. In addition to net earnings, other components of comprehensive income include the after-tax effect of changes in unrealized gains and losses on available for sales securities. These items are reported as a separate component of shareholders’ equity.

Dividend Restrictions

Banking regulations require maintaining certain capital levels and may limit dividends paid by the Bank to the Company or by the Company to shareholders. The Bank is subject to certain restrictions on the amount of dividends that may be declared without prior regulatory approval. At December 31, 2021, $9.1 million of retained earnings were available for dividend declaration without regulatory approval.

Fair Value of Financial Instruments

Fair values of financial instruments are estimated using relevant market information and other assumptions as more fully disclosed in Note 20. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect these estimates.

Revenue Recognition

The Company records revenue from contracts with customers in accordance with Accounting Standards Codification (ASC) 606, Revenue from Contracts with Customers (“ASC 606”). Under ASC 606, the Company must identify the contract with a customer, identify the performance obligation(s) within the contract, determine the transaction price, allocate the transaction price to the performance obligation(s) within the contract, and recognize revenue when (or as) the performance obligation(s) are/is satisfied. The core principle under ASC 606 requires the Company to recognize revenue to depict the transfer of services or products to customers in an amount that reflects the consideration that it expects to be entitled to receive in exchange for those services or products recognized as performance obligations are satisfied. The Company generally fully satisfies its performance obligations on its contracts with customers as services are rendered and the transaction prices are typically fixed; charged either on a periodic basis or based on activity. Since performance obligations are satisfied as services are rendered and the transaction prices are fixed, there is little judgment involved in applying ASC 606 that significantly affects the determination of the amount and timing of revenue form contracts with customers. The recognition of revenue under ASC 606 did not materially change the timing or magnitude of revenue recognition.

The majority of the Company’s revenue is not subject to ASC 606, including net interest income, loan servicing income, fees related to loans and loan commitments, increase in cash surrender value of life insurance and gain on sales of securities and loans. The following significant revenue-generating transactions are within the scope of ASC 606, which are presented in the Statements of Income as components of noninterest revenue.

Service charges and fees: The deposit contract obligates the Company to serve as a custodian of the customer’s deposited funds and is generally terminable at will be either party. This contract permits the customer to access the funds on deposit and request additional services related to the deposit account. Service charges on deposit accounts consist of account analysis fees (net fees earned on analyzed business and public checking accounts), monthly service charges, nonsufficient fund (“NSF”) charges, and other deposit account related charges. The Company’s performance obligation for account analysis fees and monthly service charges is generally satisfied, and the related revenue recognized, over the period in which the service

F-16

Summary of Significant Accounting Policies (continued)

is provided (typically on a monthly basis); while NSF charges and other deposit account related charges are largely transactional based and the related revenue is recognized at the time the service is provided.

Interchange and ATM fees: A contract between the Company, as a card-issuing bank, and its customers whereby the Company receives a transaction fee from the merchant’s bank whenever a customer uses a debit card to make a purchase. The performance obligation is completed and the fees are recognized as the service is provided (i.e., when the customer uses a debit card).

Other noninterest revenue: Other noninterest revenue includes several items, such as wire transfer income, check cashing fees, check printing fees, safe deposit box rental fees. These fees are generally recognized at the time the service is provided and/or the income is earned.

Earnings Per Share

Basic earnings per share represents income available to common shareholders divided by the weighted average number of common shares outstanding during the period. Diluted earnings per share reflect additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustments to income that would result from the assumed conversion. Potentially dilutive common shares include warrants, stock options and SERP shares outstanding that would have been converted to common shares.

Earnings per share have been computed based on the following for the years ended December 31, 2021 and 2020 (in thousands, except for share values):

	2021			2020
Net income available to common shareholders		$	13,814		4,442
Weighted average number of common shares outstanding			6,970,955		6,911,275
Effect of dilutive options, warrants, and SERP shares			238,931		215,182
Weighted average number of common shares outstanding used to calculate diluted earnings per common share			7,209,886		7,126,457

Reclassifications

Certain 2020 amounts have been reclassified to conform to the 2021 presentation.

Impact of Recently-Issued Accounting Standards and Pronouncements

ASU 2016-13 — Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). ASU 2016-13 significantly changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The standard will replace the current incurred loss approach with an expected loss model, referred to as the current expected credit loss (“CECL”) model. The new standard will apply to financial assets subject to credit losses and measured at amortized cost and certain off-balance-sheet credit exposures, which include, but are not limited to, loans, leases, held-to-maturity securities, loan commitments and financial guarantees. ASU 2016-13 simplifies the accounting for purchased credit-impaired debt securities and loans and expands the disclosure requirements regarding an entity’s assumptions, models and methods for estimating the allowance for loan losses. In addition, entities will need to disclose the amortized cost balance for each class of financial asset by credit quality indicator, disaggregated by the year of origination. ASU 2016-13 is effective for annual reporting periods beginning after December 15, 2019. In November 2019, the FASB issued Financial Instruments Credit Losses (Topic 326): Effective Dates (“ASU 2019-10”). ASU 2019-10 amends the effective date for certain entities, including the Company, for ASU 2016-13 until fiscal years beginning after December 15, 2022.

ASU 2017-04 — Intangibles: Goodwill and Other: Simplifying the Test for Goodwill Impairment (“ASU 2017-04”). ASU 2017-04 eliminates Step 2 from the goodwill impairment test to simplify the subsequent measurement of goodwill. The annual, or interim, goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. In addition, the income tax effects of tax deductible goodwill on the carrying amount of the reporting unit should be considered when measuring the goodwill impairment loss, if applicable. ASU 2017-04 also eliminates the requirement for any reporting unit with a zero or negative carrying amount to perform Step 2 of the goodwill impairment test. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The standard must be adopted using a prospective basis and the nature and reason for change in accounting principle should be disclosed upon transition. ASU 2017-04 is effective for annual goodwill impairment tests in reporting periods beginning after December 15, 2019. The Company has adopted the provisions of ASU 2017-04, and the adoption did not have a material impact on the Company’s consolidated financial statements.

ASU 2018-13 — Fair Value Measurement (Topic 820): Disclosure Framework — Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13). ASU 2018-13 changes fair value measurement disclosure requirements by removing certain requirements, modifying certain requirements and adding new requirements. Disclosure requirements removed include the following: transfers between Level 1 and Level 2 of the fair value hierarchy; the policy for determining when transfers between any of the three levels have occurred, the valuation processes for Level 3 measurements; and the changes in unrealized gains or losses presented in earnings for Level 3 instruments held at end of the reporting period. Disclosure requirements that have been modified include the following: for investment in certain entities that calculate net asset value an entity is required to disclose the timing of liquidation of an investee’s assets and the date when restrictions from redemption might lapse only if the investee has communicated the timing to the entity or announced the timing publicly, and clarification that the Level 3 measurement uncertainty disclosure should communicate information about the uncertainty at the balance sheet date. New disclosure requirements include the following: the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 instruments held at the end of the reporting period; and the range and weighted average of significant unobservable inputs used for Level 3 measurements or disclosure of other quantitative information in place of the weighted average to the extent that it would be a more reasonable and rational method to reflect the distribution of unobservable inputs. ASU 2018-13 is effective for the interim and annual period beginning after December 15, 2019. The Company has adopted the provisions of ASU 2018-13, and the adoption did not have a material impact on the Company’s consolidated financial statements.

ASU 2019-12 — Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”). ASU 2019-12 simplifies the accounting for income taxes by removing certain technical exceptions. ASU 2019-12 also clarifies and amends the accounting for income taxes in certain areas, including, among other: (i) franchise taxes that are partially based on income; (ii) whether step ups in the tax basis of goodwill should be considered part of the acquisition to which it related or recognized as a separate transaction; and (iii) requiring the effect of an enacted change in tax laws or rates to be reflected in the annual effective tax rate computation in the period that includes the enactment date. ASU 2019-12 is effective for annual periods beginning after December 15, 2020. The Company does not expect this ASU to have a material impact on the Company’s consolidated financial statements.

ASU No. 2020-04 — Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”). ASU 2020-04 provides optional guidance, for a limited time, to ease the potential burden in accounting for or recognizing the effects of reference rate reform on financial reporting. The amendments, which are elective, provide expedients and exceptions for applying GAAP to contract modifications and hedging relationships affected by reference rate reform if certain

F-18

criteria are met. The amendments apply only to contracts and hedging relationships that reference LIBOR or another reference rate that is expected to be discontinued due to reference rate reform. The optional expedients for contract modifications apply consistently for all contracts or transactions within the relevant Codification Topic, Subtopic, or Industry Subtopic that contains the guidance that otherwise would be required to be applied, while those for hedging relationships can be elected on an individual hedging relationship basis. Because the guidance is intended to assist stakeholders during the global market-wide reference rate transition period, it is in effect for a limited time, from March 12, 2020 through December 31, 2022. The Company has limited exposure to LIBOR and this is not expected to have a material impact on the Company’s consolidated financial statements.

Explanation of fair value adjustments:

Adjustment reflects the fair value adjustments based on the Company’s evaluation of the acquired loan portfolio, remove existing deferred fees and costs and the elimination of the allowance for loan losses.

Adjustment reflects the write-off of certain fixed assets and fair value adjustments of real property.

Adjustment reflects the fair value adjustment to other real estate owned.

Adjustment reflects the recording of core deposit intangible asset.

Adjustment reflects adjustment of the deferred tax asset.

Adjustment reflects the fair value adjustment to time deposit accounts.

Adjustment to reflect the fair value adjustments to junior subordinated debentures.

The accretable yield on loans will be accreted to interest income over the estimated average life of the loans using a level yield method. The Company records a non-accretable difference on PCI loans and estimates the amount and timing of expected cash flows for these loans. The core deposit intangible asset is being amortized over a ten-year life on an accelerated basis.

At December 31, 2021, there were 68 available for sale securities that were in an unrealized loss position. Residential mortgage-backed securities accounted for 41 of the securities in an unrealized loss position with 8 of these securities in a loss position for greater than 12 months. Collateralized mortgage obligations accounted for 9 of the securities in an unrealized loss position with one of these securities in a loss position for greater than 12 months. The remaining securities in a loss position were made up of 17 state and political subdivisions with 6 of these securities in a loss position for more than 12 months, and 1 corporate security that was not in a loss position for more than 12 months. At December 31, 2020, there were 24 available for sale securities that were in an unrealized loss position. Residential mortgage-backed securities accounted for 15 of the securities in an unrealized loss position with none of these securities in a loss position for greater than 12 months. Collateralized mortgage obligations accounted for 2 of the securities in an unrealized loss position with none of these securities in a loss position for greater than 12 months. The remaining securities in a loss position were made up of 7 state and political subdivisions with none of these securities in a loss position for more than 12 months.

The Company does not intend to sell nor believes it will be required to sell securities in an unrealized loss position prior to recovery of its amortized cost basis or maturity. Unrealized losses at December 31, 2021 and 2020 were primarily attributable to changes in interest rates.

The amortized cost and fair value of available for sale securities at December 31, 2021, by contractual maturity, are presented in the following table (in thousands):

	Amortized Cost			Fair Value
State and political subdivisions, commercial mortgage-backed securities, and corporate debt securities:
1 to 5 years		$	1,047		1,051
5 to 10 years			17,308		17,156

Mortgage-backed securities			168,277		165,947
		$	199,990		197,309

Expected maturities may differ from contractual maturities because borrowers have the right to call or prepay obligations with or without call or prepayment penalties.

At December 31, 2021 and 2020, securities with a carrying value of approximately $2.3 million and $85.9 million, respectively, were pledged to secure public deposits. Securities with a carrying value of $26.0 million and $16.3 million were pledged as collateral for repurchase agreements at December 31, 2021 and 2020, respectively.

Management evaluates securities for other-than-temporary impairment on at least a quarterly basis, and more frequently when economic or market concerns warrant such evaluation. Consideration is given to the length of time and the extent to which the fair value has been less than cost, the financial condition

and near-term prospects of the issuer, among other factors. In analyzing an issuer’s financial condition, management considers whether the securities are issued by the federal government or its agencies, whether downgrades by bond rating agencies have occurred, and industry reports. During 2021 and 2020, the Company did not record any impairment losses.

During the year ended December 31, 2021, the Company did not sell any available for sale securities.

At each reporting period, the Company determines which loans are impaired. Impaired loans are reviewed on a relationship basis. If one loan within a relationship is impaired, then the entire relationship is individually evaluated for impairment. An allowance for each impaired loan, which is generally collateral-dependent, is calculated based on the fair value of its collateral. The fair value of the collateral is based on appraisals, and management considers factors such as the assumptions and techniques utilized by the appraiser. If the recorded investment in the impaired loan exceeds the measure of fair value of the collateral, management will determine if a valuation allowance is recorded as a component of the allowance for loan losses or a charge off of the collateral deficiency is recorded. Management considers the factors of each relationship in making this determination. No interest income was recognized on nonaccrual loans and nonperforming troubled debt restructurings (“TDRs”) during 2021 or 2020. Interest income recognized on performing TDRs was immaterial for both 2021 and 2020.

The Company utilizes an internal risk grading matrix to assign a risk grade to each of its loans. Loans are graded on a scale of 1 to 8. These risk grades are evaluated on an ongoing basis. A description of the general characteristics of the eight risk grades is as follows:

•

Risk Grades 1 – 4, Pass: Loans exhibit adequate cash flows, appropriate management and financial ratios within industry norms and/or are supported by sufficient collateral. Some credits in these rating categories may require a need for monitoring but elements of concern are not severe enough to warrant an elevated rating.

•

Risk Grade 5, Special Mention: An OAEM loan is inadequately protected by the current sound net worth and paying capacity of the obligor or the collateral pledged, if any. There is a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. There is a distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected.

•

Risk Grade 6, Substandard: These loans have the general characteristics of a Grade 5 OAEM loan, with heightened potential concerns and a greater possibility of loss. The exact amount of loss is not yet known because neither the liquidation value of the collateral nor the borrower’s predicted repayment ability is known with confidence.

•

Risk Grade 7, Doubtful: Loans classified as Doubtful have all the weaknesses inherent in loans classified Substandard, plus the added characteristics that the weaknesses make collection or liquidation in full on the basis of currently existing facts, conditions, and values highly questionable and improbable. Doubtful is a temporary grade where a loss is expected but is presently not quantified with any degree of accuracy. Once the loss position is determined, the amount is charged off.

•

Risk Grade 8, Loss: Loans classified as Loss are considered uncollectable and continuance as an acceptable asset is not warranted. This classification does not mean that the asset has absolutely no recovery potential or salvage value, but rather that it is not practical or desirable to defer writing off this loan even though partial recovery may occur in the future. Loss is a temporary grade until the appropriate authority is obtained to charge the loan off.

The Company did not modify any loans in 2021 that would qualify as a TDR and restructured two single-family residential contracts in 2020 with a pre and post-modification recorded investment of $147,000.

During 2020 and 2021, the Company modified loans for certain customers by extending payments for 90 days or granting interest only payments for some period as a result of the COVID-19 pandemic. Accordingly, such loans were not classified as troubled debt restructurings. As of December 31, 2021, the extension period for these loans had expired with customers resuming their regular payment schedule.

Junior Subordinated Debentures

In connection with the acquisition of Heritage Bancorporation in 2019, the Company assumed the debentures issued to Liberty Shares Statutory Trust II (“Trust”). The Debt Securities represent the sole assets of the Trust. The Trust is not included in the consolidated financial statements. The debentures mature on March 15, 2036. The interest rate reprices quarterly equal to the three-month LIBOR plus 148 basis points (1.68% and 1.70% at December 31, 2021 and 2020, respectively) with interest payable quarterly.

The Company has guaranteed, on a subordinated basis, distributions and other payments due on the Trust Preferred Securities. The Company’s investment in the Trust Common Securities is included in other assets in the consolidated balance sheets. The debentures are unsecured obligations of the Company and are junior in right of all present and future indebtedness of the Company.

The debenture issued to the Trust that was assumed by the Company had a par value of $10.3 million and an unamortized discount of $907 thousand and $1.1 million at December 31, 2021 and 2020, respectively.

(13)

Subordinated Notes

On June 30, 2020, the Company completed the offering and sale of $20 million in aggregate amount of its 6.00% Fixed-to-Floating Rate Subordinated Notes due in 2030. Debt issuance costs of $373 thousand were netted with proceeds and are being amortized over the term of the notes. The subordinated notes will mature on June 30, 2030 and through June 30, 2025, bear a fixed rate of interest of 6.00% per annum, payable quarterly in arrears on March 30, June 30, September 30 and December 30 of each year. Beginning June 30, 2025, the interest rate on the subordinated notes resets quarterly to a floating rate per annum equal to the then-current one month-LIBOR plus 5.63%, payable quarterly in arrears on March 30, June 30, September 30 and December 30 of each year to the maturity date or earlier redemption. Beginning June 30, 2025, the Company may, at its option and with proper notice provided, redeem the subordinated notes, in whole or in part, at a redemption price equal to 100% of the principal amount plus accrued and unpaid interest.

Subordinated Notes (continued)

During 2021, in conjunction with the pending Purchase and Assumption Agreement with VyStar Credit Union, the Company repurchased all of the outstanding subordinated debt. Total premiums paid (including related broker fees) on the early redemption totaled $3.4 million, which was included with professional and other expenses related to pending transaction on the income statement. In addition, the Company recognized $323,000 in expense for unamortized debt issuance costs.

Related Party Transactions

The Company conducts transactions with its directors and executive officers, including companies in which they have beneficial interests, in the normal course of business. It is the policy of the Bank that loan transactions with directors and officers are made on substantially the same terms as those prevailing at the time made for comparable loans to other persons. The following is a summary of activity for related party loans for 2021 (in thousands):

Beginning balance	$	3,081
New loans and advances		1,858
Repayments		(1,861)
Ending balance	$	3,078

The Company had deposit relationships with related parties of approximately $14.5 million and $10.2 million as of December 31, 2021 and 2020, respectively.

(15)

Employee Benefit and Stock Plans

The Company has a contributory 401(k) profit sharing plan covering substantially all of its employees. The contributions to the plan are at the discretion of its board of directors. Contributions for both 2021 and 2020 were equal to one hundred percent of employee deferrals up to six percent. Total expense related to this plan was approximately $794 thousand and $766 thousand for the years ended December 31, 2021 and 2020, respectively.

The Company adopted a nonqualified supplemental executive retirement plan (“SERP”) to provide retirement benefits to certain of the Company’s executive officers and to provide death benefits for the designated beneficiaries. Under this plan, single-premium, split-dollar, whole-life insurance contracts were purchased on certain executive officers. For the years ended December 31, 2021 and 2020, the Company incurred expense of $504 thousand and $866 thousand, respectively, in conjunction with the SERP.

In 2012, the plan agreements relating to the SERP were amended to provide for the distribution of a portion of the retirement benefit in the form of Company stock as opposed to cash. The result of the amendment was the conversion of $1.7 million of the existing accrued deferred compensation obligation payable from cash to stock. The portion of the obligation payable as stock is treated as an equity award as opposed to a liability award under ASC 480-10-25; accordingly, no liability is recorded under ASC 718-20-55 implementation guidance and no expense beyond the conversion value (i.e., the grant date value of the promised stock) is recognized in accordance with equity accounting rules of ASC 718-10-35. During 2021 and 2020, 9,660 and 9,600 shares, respectively, were issued under the SERP.

As of December 31, 2021, 194,110 shares are scheduled to be issued to eight participants over a twenty-year period beginning at retirement.

The Company is the owner and beneficiary of life insurance policies on the lives of its key officers. The Company intends to use these policies to partially fund the SERP described above. During 2021, the Company purchased an additional $5.0 million of additional coverage on officers. Income related to the life insurance policies totaled approximately $900 thousand and $797 thousand for the years ended December 31,

2021 and 2020, respectively. The carrying value of the policies recorded in the balance sheets was approximately $34.6 million and $28.7 million at December 31, 2021 and 2020, respectively.

During 2018, the Company implemented its “2018 Long-Term Incentive Plan” (“Plan”) which allows for the distribution of share-based awards to be granted to officers, directors and employees from time to time as approved. An aggregate of 200,000 shares have been reserved for issuance under the Plan. The Company awarded both Stock Options and Restricted Stock under this Plan.

Options constitute both incentive and non-qualified stock options.

A summary of stock option activity and changes during the years ended December 31, 2021 and 2020 is presented below.

	Shares		Weighted Average Exercise Price			Weighted Average Remaining Contractual Term
Outstanding, December 31, 2020		39,547		$	9.59

Outstanding, December 31, 2021		38,254			9.72		3.8
Options exercisable at end of year		34,395			9.58		3.7

Total compensation costs related to stock options was $71 thousand for the years ended December 31, 2021 and 2020. As of December 31, 2021, there was $18 thousand of unrecognized compensation costs related to unvested stock options that will be recognized ratably over the remaining vesting period of less than one year.

The Company awarded restricted shares of common stock to certain employees and directors which vest over a three to five-year period based on service and performance. Any restricted stock that has not vested at the time of the termination of the recipient’s service relationship will be forfeited. The shares were valued based on the market price at the time of grant.

Compensation expense related to restricted stock awards recognized during the years ended December 31, 2021 and 2020 was $661 thousand and $805 thousand, respectively. As of December 31, 2021, the Company estimates $155 thousand in unrecognized compensation expense for restricted stock granted.

The following tables summarizes non-vested restricted stock awards.

Commitments

The Company is party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of their customers. These financial instruments include commitments to extend credit and letters of credit. These instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the balance sheet. The notional contract amounts of these instruments reflect the extent of involvement the Company has in particular classes of financial instruments.

The exposure to credit loss in the event of nonperformance by the counter party for commitments to extend credit and letters of credit written is represented by the contractual or notional amount of these instruments. The Company uses the same credit policies in making commitments and conditional obligations as it uses for underwriting on-balance sheet instruments. In most cases, collateral or other security is required to support financial instruments with a credit risk.

The following table summarizes, as of December 31, 2021 and 2020, the contract amount of off-balance sheet instruments (in thousands):

	2021			2020
Financial instruments whose contract amounts represent credit risk:
Commitments to extend credit		$	404,353		260,461
Financial and performance letters of credit			5,286		5,334
		$	409,639		265,795

Commitments to extend credit are arrangements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments may expire without being drawn on, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness and subjects commitments to typical credit underwriting on a case-by-case basis. The amount of collateral obtained, if deemed necessary, upon extension of credit is based on management’s credit evaluation. Collateral held varies, but may include unimproved and improved real estate, certificates of deposit, personal property or other acceptable collateral.

Commercial letters of credit are issued to facilitate commerce and typically result in the commitment being drawn on when the underlying transaction is consummated between the customer and the third party. Those guarantees are primarily issued to local businesses. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The Bank holds real estate, certificates of deposit, and other acceptable collateral as security supporting those commitments for which collateral is deemed necessary. The extent of collateral held for those commitments varies.

At December 31, 2021 and 2020, the Company had $20.0 million and $28.4 million, respectively, available for the purchase of unsecured overnight federal funds from two correspondent financial institutions.

Regulatory Matters

The Bank is subject to various regulatory capital requirements administered by federal and state banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary action by regulators that, if undertaken, could have a direct material effect on the Bank’s financial statements. Under capital adequacy rules and the regulatory framework for prompt corrective action, as revised by the Basel III Capital Rules effective as of January 1, 2015, the Bank must meet specific capital thresholds that involve quantitative measures of capital, assets, and certain off-balance sheet items as calculated under regulatory rules. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Quantitative measures (as defined) established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios of total capital, Tier 1 capital, and common equity Tier 1 capital (“CET 1”) to risk-weighted assets, and of Tier 1 capital to average assets, the Tier 1 leverage ratio.

Effective January 1, 2015, the Basel III Capital Rules revised the framework for prompt corrective action by (1) introducing a CET 1 ratio requirement at each level (other than critically undercapitalized), with the required CET 1 ratio being 6.5% for well capitalized status; (2) increasing the minimum Tier 1 capital ratio requirement for each category (other than critically undercapitalized), with the minimum Tier 1 capital ratio for well capitalized status being 8% (as compared to the prior 6%); and (3) eliminating the current provision that provides that a bank with a composite supervisory rating of 1 may have a 3% leverage ratio and still be adequately capitalized.

As of December 31, 2021, the Bank was categorized as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, the Bank must maintain minimum guideline ratios as set forth in the table below. There are no conditions or events since December 31, 2021 that management believes have changed the Bank’s category.

The Bank’s actual capital amounts and ratios are presented below (dollars in thousands):

	Actual					For Capital Adequacy Purposes					To Be Well Capitalized Under Prompt Corrective Action Provisions

Fair Value Measurement and Disclosures

Fair value measurements are determined based on the assumptions that market participants would use in pricing an asset or liability. As a basis for considering market participant assumptions in fair value measurements, ASC Topic 820, Fair Value Measurements and Disclosures establishes a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are utilized in the determination of fair value for instruments classified within Levels 1 and 2 of the hierarchy) and the reporting entity’s own assumptions about market participant assumptions (unobservable inputs for instruments classified within Level 3 of the hierarchy).

Fair Value Hierarchy

	Level 1 -			Valuation is based upon quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access.
	Level 2 -			Valuation is based upon quoted prices for similar assets or liabilities in active markets, as well as inputs that are observable for the asset or liability (other than quoted prices), such as interest rates and yield curves that are observable at commonly quoted intervals.
	Level 3 -			Valuation is generated from model-based techniques that use at least one significant assumption based on unobservable inputs for the asset or liability, which are typically based on an entity’s own assumptions, as there is little, if any, related market activity. In instances in which the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability.

The following methods and assumptions were used by the Company in estimating the fair value of its significant financial instruments and other accounts recorded or disclosed based on their fair value:

Cash and Cash Equivalents

For cash, due from banks, interest-bearing deposits in banks and federal funds sold, the carrying amount approximates fair value.

Securities

Securities available for sale are recorded at fair value on a recurring basis. Securities held to maturity are recorded at amortized cost. For securities available for sale, as well as securities held to maturity, the fair value is determined by various valuation methodologies. Where quoted market prices are available in active markets, securities are classified within Level 1 of the valuation hierarchy. If quoted market prices are not available, fair values are estimated by using pricing models, quoted prices of securities with similar characteristics, or discounted cash flows. Level 2 securities include certain U.S. agency bonds, collateralized mortgage and debt obligations, and certain municipal securities. The Level 2 fair value pricing is provided by an independent third party and is based upon similar securities in an active market.

Other Investments

FHLB stock is included in other investment securities at its original cost basis, as cost approximates fair value and there is no ready market for such investments.

Fair Value Measurement and Disclosures (continued)

Loans

The carrying amount of variable-rate loans that reprice frequently and have no significant change in credit risk approximates fair value. The fair value of fixed-rate loans is estimated based on discounted contractual cash flows, using interest rates currently being offered for loans with similar terms to borrowers with similar credit quality. The fair value of impaired loans is estimated based on discounted contractual cash flows or underlying collateral values, where applicable. A loan is determined to be impaired if the Company believes it is probable that all principal and interest amounts due according to the terms of the note will not be collected as scheduled. The fair value of impaired loans is determined in accordance with generally accepted accounting principles and generally results in a specific reserve established through a charge to the provision for loan losses.

Losses on impaired loans are charged to the allowance when management believes the collectability of a loan is confirmed. Management classifies all impaired loans carried at fair value as Level 3, since their valuations are based on either discounted cash flows or on underlying collateral values, as determined by appraisals, which are based in part on observable inputs, but which are not themselves observable inputs.

Other Real Estate Owned

The fair value of OREO is determined using certified appraisals that assign value to the property at its highest and best uses by applying traditional valuation methods common to the industry. The Company does not hold any OREO for profit purposes and all OREO is actively marketed for sale. In most cases, management has determined that additional valuation adjustments may be appropriate to reflect other market factors that may not be captured in the appraisal. Accordingly, appraisals as adjusted are not based on observable inputs, and management has determined that OREO should be classified as Level 3.

Cash Surrender Value of Bank Owned Life Insurance

The carrying value of these assets approximates fair value.

Deposits

The carrying amount of demand deposits, savings deposits and variable-rate certificates of deposits approximates fair value. The fair value of fixed-rate certificates of deposits is estimated based on discounted contractual cash flows using interest rates currently being offered for certificates of similar maturities.

Securities Sold Under Agreements to Repurchase

The carrying amount of securities sold under agreements to repurchase approximates fair value.

Federal Home Loan Bank Advances

The carrying amount of variable rate advances approximates fair value. The fair value of fixed rate advances is estimated based on discounted contractual cash flows using the current incremental borrowing rates for similar type borrowing arrangements.

Lines of Credit

The carrying amount of the variable rate lines of credit approximates fair value.

Subordinated Notes

The carrying amount of the variable rate subordinated notes approximates fair value.

Fair Value Measurement and Disclosures (continued)

Junior Subordinated Debentures

The carrying amount of the variable rate trust preferred securities approximates fair value.

Commitments to Extend Credit

PART II
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.

Item 21. Exhibits and Financial Statements

A list of the exhibits included as part of this registration statement is set forth in the Exhibit Index that immediately precedes such exhibits and is incorporated herein by reference.

Item 22. Undertakings

(a) The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by section 10(a)(3) of the Securities Act of 1933;

II-1

TABLE OF CONTENTS

(ii) To reflect in the prospectus any facts or events arising after the effective date of this registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement;

(iii) To include any material information with respect to the plan of distribution not previously disclosed in this registration statement or any material change to such information in this registration statement;

(2) That, for the purpose 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.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement 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.

(c) The undersigned registrant hereby undertakes as follows: that prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form.

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.
