PROXY STATEMENT/PROSPECTUS

MERGER PROPOSED-YOUR VOTE IS VERY IMPORTANT

Dear Shareholders of Landmark Community Bank:

On September 7 , 2021 we will hold a special meeting of the shareholders of Landmark Community Bank, or Landmark, to vote on a proposal to merge with Simmons Bank, an Arkansas state-chartered bank and wholly owned subsidiary of Simmons First National Corporation, or Simmons, an Arkansas corporation and the parent holding company of Simmons Bank. On June 4, 2021, Simmons, Simmons Bank and Landmark entered into an Agreement and Plan of Merger, which we refer to as the Landmark merger agreement, that provides for the merger of Landmark with and into Simmons Bank, with Simmons Bank as the surviving bank in the merger, which we refer to as the Landmark merger.

Based on the assumptions set forth below, under the terms of the Landmark merger agreement, each share of common stock, no par value per share, of Landmark, which we refer to as Landmark common stock, that is issued and outstanding immediately prior to the effective time of the Landmark merger, which we refer to as the Landmark effective time, excluding certain specified shares, will be converted into the right to receive, subject to possible adjustment, (1) approximately 0.2025 shares of common stock, $0.01 par value per share, of Simmons, which we refer to as the Landmark stock consideration, with cash paid in lieu of fractional shares, and (2) $0.29 in cash, which we refer to as the Landmark cash consideration, and together with the Landmark stock consideration, the Landmark merger consideration. In the aggregate, Simmons expects to issue approximately 4,500,000 shares of common stock, $0.01 par value per share, of Simmons, which we refer to as Simmons common stock, and pay approximately $7,000,000 (minus the cash payment for outstanding stock options of Landmark) to Landmark shareholders upon completion of the Landmark merger, subject to certain conditions and potential adjustments under the Landmark merger agreement. The Landmark merger consideration is based on the assumption that (i) 22,215,981 shares of Landmark common stock are issued and outstanding and (ii) 218,400 shares of Landmark common stock are subject to outstanding stock options of Landmark with a weighted average exercise price of $3.49 , in each case, immediately prior to the Landmark effective time. In addition, we have assumed that the Landmark/Simmons average closing price (as described herein) is equal to $27.49, which was the closing sales price of Simmons common stock on July 29, 2021, the last practicable trading day prior to printing this proxy statement/prospectus.

In addition to the Landmark merger, Simmons and Triumph Bancshares, Inc., or Triumph, a Tennessee corporation and the parent company of Triumph Bank, a Tennessee state-chartered bank and a wholly owned subsidiary of Triumph, have also entered into an Agreement and Plan of Merger, which we refer to as the Triumph merger agreement, that provides for (i) the merger of Triumph with and into Simmons, with Simmons as the

surviving corporation in the merger, which we refer to as the Triumph merger, and (ii) immediately following the Triumph merger, the merger of Triumph Bank with and into Simmons Bank, with Simmons Bank as the surviving bank. Triumph is headquartered in Memphis, Tennessee, operates out of six branches located in the Memphis and Nashville Metropolitan statistical areas, and had total assets of approximately $0.9 billion as of March 31, 2021. Based on the assumptions set forth below, under the terms of the Triumph merger agreement, each share of common stock, $1.00 par value per share, of Triumph, which we refer to as Triumph common stock, that is issued and outstanding immediately prior to the effective time of the Triumph merger, which we refer to as the Triumph effective time, excluding certain specified shares, will be converted into the right to receive, subject to possible adjustment, (1) approximately 0.9081 shares of Simmons common stock, which we refer to as the Triumph stock consideration, with cash paid in lieu of fractional shares, and (2) $ 0.36 in cash, which we refer to as the Triumph cash consideration, and together with the Triumph stock consideration, the Triumph merger consideration. In the aggregate, Simmons expects to issue approximately 4,164,839 shares of common stock and pay approximately $ 2,645,937.83 (minus the cash payment for outstanding stock options of Triumph) to Triumph shareholders upon completion of the Triumph merger, subject to certain conditions and potential adjustments under the Triumph merger agreement. The Triumph merger consideration is based on the assumption that (i) 4,586,300 shares of Triumph common stock are issued and outstanding and (ii) 148,763 shares of Triumph common stock are subject to outstanding stock options of Triumph with a weighted average exercise price of $ 18.67 , in each case, immediately prior to the Triumph effective time. In addition, we have assumed that the Triumph/Simmons average closing price (as described herein) is equal to $ 27.49 , which was the closing sales price of Simmons common stock on July 29, 2021, the last practicable trading day prior to printing this proxy statement/prospectus.

The market value of the Landmark merger consideration and the Triumph merger consideration will fluctuate with the price of Simmons common stock. At the time of the special meetings of Landmark shareholders and Triumph shareholders, the Landmark shareholders and Triumph shareholders will not know or be able to calculate the value of the merger consideration to be received upon completion of the Landmark merger or the Triumph merger, respectively. Based on the closing sale price per share of Simmons common stock on June 4, 2021, the last trading day before the public announcement of the signing of the Landmark merger agreement and the Triumph merger agreement, and on July 29 , 2021, the last practicable trading day prior to printing this proxy statement/prospectus, and on certain assumptions as described elsewhere in this proxy statement/prospectus, the implied value of the aggregate merger consideration payable is approximately $146,320,000.00, or $6.56 per share of Landmark common stock, and approximately $130,705,000.00, or $5.86 per share of Landmark common stock, respectively (such per share amounts exclude the cash payment for outstanding stock options of Landmark) . We urge you to obtain current market quotations for Simmons common stock, which is traded on the Nasdaq Global Select Market under the symbol “SFNC.”

While the Triumph shareholders will need to approve the Triumph merger for it to be consummated, the Landmark shareholders will not be required to approve the Triumph merger. Information included in this proxy statement/prospectus with respect to Triumph and the Triumph merger is provided as information for Landmark shareholders to consider when voting upon the Landmark merger.

If the Landmark merger and the Triumph merger, which we refer to collectively as the mergers, are both completed, existing Simmons shareholders would own approximately 92.60 % of Simmons common stock immediately following completion of the mergers, while former Landmark shareholders would own approximately 3.84 % and former Triumph shareholders would own approximately 3.56 %. If the Landmark merger is completed but the Triumph merger is not completed, existing Simmons shareholders and Landmark shareholders would own approximately 96.01 % and 3.99 %, respectively, of Simmons common stock upon completion of the Landmark merger.

Neither the closing of the Landmark merger nor the closing of the Triumph merger is conditioned upon closing of the other merger.

ii

Landmark will hold a special meeting of its shareholders in connection with the Landmark merger. Simmons and Landmark cannot complete the Landmark merger unless the holders of Landmark common stock approve the Landmark merger agreement and the transactions contemplated thereby, including the Landmark merger. Landmark’s board of directors, or the Landmark board of directors, is providing this document to solicit Landmark shareholders’ proxy to vote in connection with the Landmark merger agreement and related matters. This document is also being delivered to Landmark shareholders and Triumph shareholders as Simmons’ prospectus for its offering of Simmons common stock in connection with the mergers.

The Landmark special meeting will be held on September 7 , 2021, at 6:00 p.m. Central Time, at the Hunt & Polo Club, 650 Shady Grove Road, Memphis, Tennessee 38120 .

Landmark shareholders, your vote is very important.

To ensure your representation at the Landmark special meeting, please complete, sign, date and return the enclosed proxy. Sending in your proxy will not prevent you from voting your shares personally at the Landmark special meeting, since you may revoke your proxy at any time before it is voted.

The Landmark board of directors approved the Landmark merger agreement and the transactions contemplated thereby and recommends that Landmark shareholders vote “FOR” approval of the Landmark merger agreement, and, if necessary or appropriate, “FOR” the proposal to adjourn the Landmark special meeting to solicit additional proxies in favor of the Landmark merger agreement.

This proxy statement/prospectus describes the special meeting of Landmark, the special meeting of Triumph, the Landmark merger, the Triumph merger, the documents related to the mergers and other related matters. Please carefully read this entire proxy statement/prospectus, including “Risk Factors,” beginning on page 32 for a discussion of the risks relating to the proposed mergers. You also can obtain information about Simmons from documents that it has filed with the Securities and Exchange Commission.

PROXY STATEMENT/PROSPECTUS

MERGER PROPOSED-YOUR VOTE IS VERY IMPORTANT

Dear Shareholders of Triumph Bancshares, Inc.:

On September 7 , 2021 we will hold a special meeting of the shareholders of Triumph Bancshares, Inc., or Triumph, to vote on a proposal to merge with Simmons First National Corporation, or Simmons, an Arkansas corporation and the parent holding company of Simmons Bank, an Arkansas state-chartered bank and wholly owned subsidiary of Simmons. On June 4, 2021, Simmons and Triumph entered into an Agreement and Plan of Merger, which we refer to as the Triumph merger agreement, that provides for (i) the merger of Triumph with and into Simmons, with Simmons as the surviving corporation in the merger, which we refer to as the Triumph merger, and (ii) immediately following the Triumph merger, the merger of Triumph Bank with and into Simmons Bank, with Simmons Bank as the surviving bank.

Based on the assumptions set forth below, under the terms of the Triumph merger agreement, each share of common stock, $1.00 par value per share, of Triumph, which we refer to as Triumph common stock, that is issued and outstanding immediately prior to the effective time of the Triumph merger, which we refer to as the Triumph effective time, excluding certain specified shares, will be converted into the right to receive, subject to possible adjustment, (1) approximately 0.9081 shares of common stock, $0.01 par value per share, of Simmons, which we refer to as the Triumph stock consideration, with cash paid in lieu of fractional shares, and (2) $ 0.36 in cash, which we refer to as the Triumph cash consideration, and together with the Triumph stock consideration, the Triumph merger consideration. In the aggregate, Simmons expects to issue approximately 4,164,839 shares of common stock, $0.01 par value per share, of Simmons, which we refer to as Simmons common stock, and pay approximately $ 2,645,937.83 (minus the cash payment for outstanding stock options of Triumph) to Triumph shareholders upon completion of the Triumph merger, subject to certain conditions and potential adjustments under the Triumph merger agreement. The Triumph merger consideration is based on the assumption that (i) 4,586,300 shares of Triumph common stock are issued and outstanding and (ii) 148,763 shares of Triumph common stock are subject to outstanding stock options of Triumph with a weighted average exercise price of $ 18.67 , in each case, immediately prior to the Triumph effective time. In addition, we have assumed that the Triumph/Simmons average closing price (as described herein) is equal to $27.49, which was the closing sales price of Simmons common stock on July 29, 2021, the last practicable trading day prior to printing this proxy statement/prospectus.

In addition to the Triumph merger, Simmons, Simmons Bank and Landmark Community Bank, or Landmark, a Tennessee state-chartered bank, have also entered into an Agreement and Plan of Merger, which we refer to as the Landmark merger agreement, that provides for the merger of Landmark with and into Simmons Bank, with Simmons Bank as the surviving bank in the merger, which we refer to as the Landmark merger. Landmark is headquartered in Collierville, Tennessee, operates out of eight branches located in the Memphis and Nashville Metropolitan statistical areas, and had total assets of approximately $1.0 billion as of March 31, 2021. Based on the assumptions set forth below, under the terms of the Landmark merger agreement, each share of common stock, no par value per share, of Landmark, which we refer to as Landmark common stock, that is issued and outstanding immediately prior to the effective time of the Landmark merger, which we refer to as the Landmark effective time, excluding certain specified shares, will be converted into the right to receive, subject to possible adjustment, (1) approximately 0.2025 shares of Simmons common stock, which we refer to as the Landmark stock consideration, with cash paid in lieu of fractional shares, and (2) $0.29 in cash, which we refer to as the Landmark cash consideration, and together with the Landmark stock consideration, the Landmark merger consideration. In the aggregate, Simmons expects to issue approximately 4,500,000 shares of common stock and pay approximately

iv

$7,000,000 (minus the cash payment for outstanding stock options of Landmark) to Landmark shareholders upon completion of the Landmark merger, subject to certain conditions and potential adjustments under the Landmark merger agreement. The Landmark merger consideration is based on the assumption that (i) 22,215,981 shares of Landmark common stock are issued and outstanding and (ii) 218,400 shares of Landmark common stock are subject to outstanding stock options of Landmark with a weighted average exercise price of $3.49, in each case, immediately prior to the Landmark effective time. In addition, we have assumed that the Landmark/Simmons average closing price (as described herein) is equal to $27.49 , which was the closing sales price of Simmons common stock on July 29, 2021, the last practicable trading day prior to printing this proxy statement/prospectus.

The market value of the Triumph merger consideration and the Landmark merger consideration will fluctuate with the price of Simmons common stock. At the time of the special meetings of Triumph shareholders and Landmark shareholders, the Triumph shareholders and Landmark shareholders will not know or be able to calculate the value of the merger consideration to be received upon completion of the Triumph merger or the Landmark merger, respectively. Based on the closing sale price per share of Simmons common stock on June 4, 2021, the last trading day before the public announcement of the signing of the Triumph merger agreement and the Landmark merger agreement, and on July 29 , 2021, the last practicable trading day prior to printing this proxy statement/prospectus, and on certain assumptions as described elsewhere in this proxy statement/prospectus, the implied value of the aggregate merger consideration payable is approximately $ 131,589,353.27 , or $ 28.38 per share of Triumph common stock, and approximately $ 117,137,361.94 , or $ 25.32 per share of Triumph common stock, respectively (such per share amounts exclude the cash payment for outstanding stock options of Triumph) . We urge you to obtain current market quotations for Simmons common stock, which is traded on the Nasdaq Global Select Market under the symbol “SFNC.”

Triumph’s board of directors, or the Triumph board of directors, may terminate the Triumph merger agreement if the Triumph/Simmons average closing price is below a threshold specified in the Triumph merger agreement and below a threshold relative to the Nasdaq Bank Index, as further described in the accompanying proxy statement/prospectus. If the Triumph board of directors terminates the Triumph merger agreement, Simmons may prevent the Triumph merger agreement from being terminated by increasing the Triumph cash consideration. See the section entitled “The Merger Agreements—Termination of the Merger Agreements.”

While Landmark shareholders will need to approve the Landmark merger for it to be consummated, the Triumph shareholders will not be required to approve the Landmark merger. Information included in this proxy statement/prospectus with respect to Landmark and the Landmark merger is provided as information for Triumph shareholders to consider when voting upon the Triumph merger.

If the Triumph merger and Landmark merger, which we refer to collectively as the mergers, are both completed, existing Simmons shareholders would own approximately 92.60 % of Simmons common stock immediately following completion of the mergers, while former Triumph shareholders would own approximately 3.56 % and former Landmark shareholders would own approximately 3.84 %. If the Triumph merger is completed but the Landmark merger is not completed, existing Simmons shareholders and Triumph shareholders would own approximately 96.30 % and 3.70 %, respectively, of Simmons common stock upon completion of the Triumph merger.

Neither the closing of the Triumph merger nor the closing of the Landmark merger is conditioned upon closing of the other merger.

Triumph will hold a special meeting of its shareholders in connection with the Triumph merger. Simmons and Triumph cannot complete the Triumph merger unless the holders of Triumph common stock approve the Triumph merger agreement and the transactions contemplated thereby, including the Triumph merger. The Triumph board of directors is providing this document to solicit Triumph shareholders’ proxy to vote in connection with the Triumph merger agreement and related matters. This document is also being delivered to Triumph shareholders and Landmark shareholders as Simmons’ prospectus for its offering of Simmons common stock in connection with the mergers.

Notice is hereby given that Triumph Bancshares, Inc., which we refer to as Triumph, will hold a special meeting of holders of common stock, $1.00 par value per share, of Triumph, or Triumph common stock, which we refer to as the Triumph special meeting, on September 7 , 2021, at 6:00 p.m. Central Time, at Chickasaw Country Club, 3395 Galloway Avenue, Memphis, Tennessee 38122. The Triumph special meeting will be held for the purposes of allowing holders of Triumph common stock, or Triumph shareholders, to consider and vote upon the following matters:

| · | a proposal to approve the Agreement and Plan of Merger, dated as of June 4, 2021, which we refer to as the Triumph merger agreement, by and between Simmons First National Corporation, which we refer to as Simmons, and Triumph, pursuant to which, among other things, Triumph will merge with and into Simmons, with Simmons as the surviving corporation, which we refer to as the merger, as more fully described in the attached proxy statement/prospectus, which we refer to as the Triumph merger proposal; and
| · | a proposal to approve one or more adjournments of the Triumph special meeting, if necessary or appropriate, to solicit additional proxies in favor of approval of the Triumph merger proposal, which we refer to as the Triumph adjournment proposal.

These proposals are described in greater detail in the enclosed proxy statement/prospectus. Triumph will transact no other business at the Triumph special meeting, except for the business properly brought before the Triumph special meeting or any adjournment or postponement thereof.

Triumph has fixed the close of business on August 2, 2021 as the record date for the Triumph special meeting. Only Triumph shareholders of record at that time are entitled to notice of, and to vote at, the Triumph special meeting, or any adjournment or postponement thereof. Approval of the Triumph merger proposal requires the affirmative vote of holders of at least a majority of the outstanding shares of Triumph common stock entitled to vote on the Triumph merger proposal. Approval of the Triumph adjournment proposal requires the votes cast by the outstanding shares of Triumph common stock present or represented by proxy at the Triumph special meeting and entitled to vote on the proposal favoring the approval to exceed the votes cast opposing the approval. At the close of business on the record date, 4,586,300 shares of Triumph common stock were outstanding and entitled to vote.

Your vote is very important. Simmons and Triumph cannot complete the Triumph merger unless Triumph shareholders approve the Triumph merger agreement.

To ensure your representation at the Triumph special meeting, please complete, sign, date and return the enclosed proxy by following the instructions on your proxy. If your shares of Triumph common stock are held in “street name” by a bank, broker or other nominee, please follow the instructions on the voting instruction form provided by the record holder. Sending in your proxy will not prevent you from voting your shares personally at the Triumph special meeting, since you may revoke your proxy at any time before it is voted.

Under Tennessee law, Triumph shareholders who do not vote in favor of the Triumph merger proposal and follow certain procedural steps will be entitled to dissenters’ rights. See the section entitled “Questions and Answers—Are Landmark shareholders or Triumph shareholders entitled to dissenters’ rights?” and Annex G, which contains Section 48-23-101 through Section 48-23-302 of the Tennessee Business Corporation Act, or the dissenters’ rights statutes.

QUESTIONS AND ANSWERS

The following are some questions that you may have about the mergers, as described below, the Landmark special meeting and the Triumph special meeting, as described below, and brief answers to those questions. We urge you to read carefully the remainder of this proxy statement/prospectus because the information in this section does not provide all of the information that might be important to you with respect to the mergers, the Landmark special meeting or the Triumph special meeting. Additional important information is also contained in the documents incorporated by reference into this proxy statement/prospectus. See the section entitled “Where You Can Find More Information.”

Unless the context otherwise requires, references in this proxy statement/prospectus to “Simmons” refer to Simmons First National Corporation, an Arkansas corporation; references to “Landmark” refer to Landmark Community Bank, a Tennessee state-chartered bank; references to “Triumph” refer to Triumph Bancshares, Inc., a Tennessee corporation; references to “Triumph Bank” refer to Triumph Bank, a Tennessee state-chartered bank and a wholly owned subsidiary of Triumph; and references to “we,” “our” and “us” refer to Simmons, Landmark and Triumph together.

As described below, it is important to note that the amount of merger consideration for each of the mergers may increase or decrease due to changes in the price of Simmons common stock or the fully diluted number of shares of Landmark common stock or Triumph common stock, as applicable, outstanding after the date hereof. As a result, merger consideration for each of the mergers shown throughout this proxy statement/prospectus is for illustrative purposes only based on the assumptions described herein.

| Q: | What are the mergers?

| A: | Simmons, Simmons Bank and Landmark have entered into an Agreement and Plan of Merger, dated as of June 4, 2021, which we refer to as the Landmark merger agreement, and Simmons and Triumph have entered into an Agreement and Plan of Merger, dated as of June 4, 2021, which we refer to as the Triumph merger agreement, and collectively we refer to the Landmark merger agreement and the Triumph merger agreement as the merger agreements. Under the Landmark merger agreement, Landmark will merge with and into Simmons Bank, with Simmons Bank as the surviving bank, which we refer to as the Landmark merger. Under the Triumph merger agreement, (i) Triumph will merge with and into Simmons, with Simmons as the surviving corporation, which we refer to as the Triumph merger, and collectively with the Landmark merger, the mergers, and (ii) immediately following the Triumph merger, Triumph Bank will merge with and into Simmons Bank, with Simmons Bank as the surviving bank, which we refer to as the Triumph Bank merger. Copies of the Landmark merger agreement and the Triumph merger agreement are attached to this proxy statement/prospectus as Annex A and Annex B, respectively.

The Landmark merger cannot be completed unless, among other things, the holders of Landmark common stock, no par value per share, which we refer to as the Landmark common stock, approve the proposal to approve the Landmark merger agreement. Separately, the Triumph merger cannot be completed unless, among other things, the holders of Triumph common stock, par value $1.00 per share, which we refer to as the Triumph common stock, approve the proposal to approve the Triumph merger agreement.

| Q: | Is the consummation of one merger conditioned on the consummation of the other merger?

| A: | No. The Landmark merger may be consummated regardless of whether the Triumph merger is consummated and the Triumph merger may be consummated regardless of whether the Landmark merger is consummated.

1

| Q: | Why am I receiving this proxy statement/prospectus?

| A: | We are delivering this document to the holders of Landmark common stock, which we refer to as Landmark shareholders, and the holders of Triumph common stock, which we refer to as Triumph shareholders, because it is a proxy statement being used by the each of the boards of directors of Landmark and Triumph, which we refer to as the Landmark board of directors and the Triumph board of directors, respectively, to solicit proxies of its respective shareholders in connection with approval of the respective mergers and related matters.

In order to approve the mergers and related matters, Landmark and Triumph have each called a special meeting of their shareholders, which we refer to as the Landmark special meeting and the Triumph special meeting, respectively. This document serves as a proxy statement for the Landmark special meeting and the Triumph special meeting, which we refer to collectively as the special meetings, and describes the proposals to be presented at the special meetings.

This document is also a prospectus that is being delivered to Landmark shareholders and Triumph shareholders because Simmons is offering shares of its common stock, par value $0.01 per share, which we refer to as Simmons common stock, to Landmark shareholders and Triumph shareholders as partial consideration for the Landmark merger and the Triumph merger, respectively.

This proxy statement/prospectus contains important information about the mergers and the other proposals being voted on at the special meetings. You should read it carefully and in its entirety. The enclosed materials allow you to have your shares voted by proxy without attending your meeting. Your vote is important. We encourage you to submit your proxy as soon as possible.

| Q: | What am I being asked to vote on?

| A: | Landmark Special Meeting: Landmark is soliciting proxies from its shareholders with respect to (i) a proposal to approve the Landmark merger agreement, a copy of which is attached as Annex A to this proxy statement/prospectus, and the transactions contemplated thereby, including the Landmark merger, which we refer to as the Landmark merger proposal, and (ii) a proposal to adjourn the Landmark special meeting, if necessary or appropriate, to solicit additional proxies in favor of the Landmark merger proposal, which we refer to as the Landmark adjournment proposal.

|  | Shareholder approval of the Landmark merger proposal is required to complete the Landmark merger. Completion of the Landmark merger is not conditioned upon approval of the Landmark adjournment proposal. Landmark expects that the Landmark adjournment proposal will not be brought before the Landmark special meeting if there are sufficient votes to approve the Landmark merger proposal. Landmark will transact no other business at the Landmark special meeting, except for the business properly brought before the Landmark special meeting or any adjournment or postponement thereof.

|  | Triumph Special Meeting: Triumph is soliciting proxies from its shareholders with respect to (i) a proposal to approve the Triumph merger agreement, a copy of which is attached as Annex B to this proxy statement/prospectus, and the transactions contemplated thereby, including the Triumph merger, which we refer to as the Triumph merger proposal, and (ii) a proposal to adjourn the Triumph special meeting, if necessary or appropriate, to solicit additional proxies in favor of the Triumph merger proposal, which we refer to as the Triumph adjournment proposal.

Shareholder approval of the Triumph merger proposal is required to complete the Triumph merger. Completion of the Triumph merger is not conditioned upon approval of the Triumph adjournment proposal. Triumph expects that the Triumph adjournment proposal will not be brought before the Triumph

2

special meeting if there are sufficient votes to approve the Triumph merger proposal. Triumph will transact no other business at the Triumph special meeting, except for the business properly brought before the Triumph special meeting or any adjournment or postponement thereof.

| Q: | What will Landmark shareholders receive in the merger?

| A: | Based on the assumptions set forth below, at the time the Landmark merger is completed, which we refer to as the Landmark effective time, each share of Landmark common stock that is issued and outstanding immediately prior to the Landmark effective time, excluding certain specified shares, will be converted into the right to receive, subject to possible adjustment, (i) approximately 0.2025 shares of Simmons common stock, which we refer to as the Landmark stock consideration, with cash paid in lieu of fractional shares, and (ii) $0.29 in cash, which we refer to as the Landmark cash consideration, and together with the Landmark stock consideration, the Landmark merger consideration. In the aggregate, Simmons expects to issue approximately 4,500,000 shares of Simmons common stock and pay approximately $7,000,000 (minus the cash payment for outstanding options to purchase shares of Landmark common stock, which we refer to as Landmark stock options) to Landmark shareholders upon completion of the Landmark merger, subject to certain conditions and potential adjustments under the Landmark merger agreement. The Landmark merger consideration is based on the assumption that (A) 22,215,981 shares of Landmark common stock are issued and outstanding and (B) 218,400 shares of Landmark common stock are subject to outstanding Landmark stock options with a weighted average exercise price of $3.49, in each case, immediately prior to the Landmark effective time. In addition, we have assumed that the Landmark/Simmons average closing price (as described below) is equal to $27.49, which was the closing sales price of Simmons common stock on July 29, 2021, the last practicable trading day prior to printing this proxy statement/prospectus.

|  | Simmons will not issue any fractional shares of Simmons common stock in the Landmark merger. Instead, a Landmark shareholder who would otherwise be entitled to a fractional share of Simmons common stock will receive, in lieu thereof, an amount in cash, rounded up to the nearest whole cent (without interest), determined by multiplying (i) the fraction of a share (rounded to the nearest thousandth when expressed in decimal form) of Simmons common stock that such Landmark shareholder would otherwise be entitled to receive by (ii) the average of the daily closing prices of shares of Simmons common stock for the 20 consecutive full trading days on which shares are actually traded on the Nasdaq Global Select Market, or Nasdaq, ending at the close of trading on the tenth business day prior to the Landmark effective time (or the immediately preceding day to the tenth business day prior to the Landmark effective time if shares of Simmons common stock are not actually traded on Nasdaq on such day), which average we refer to as the Landmark/Simmons average closing price.

If the mergers are both completed, existing Simmons shareholders would own approximately 92.60 % of Simmons common stock immediately following completion of the mergers, while former Landmark shareholders would own approximately 3.84 % and former Triumph shareholders would own approximately 3.56 %. If the Landmark merger is completed, but the Triumph merger is not completed, existing Simmons shareholders and Landmark shareholders would own approximately 96.01 % and 3.99 %, respectively, of Simmons common stock upon completion of the Landmark merger.

| Q: | What will Triumph shareholders receive in the merger?

| A: | Based on the assumptions set forth below, at the time the Triumph merger is completed, which we refer to as the Triumph effective time, each share of Triumph common stock that is issued and outstanding immediately prior to the Triumph effective time, excluding certain specified shares, will be converted into the right to receive, subject to possible adjustment, (i) approximately 0.9081 shares of Simmons common stock, which we refer to as the Triumph stock consideration, with cash paid in lieu of fractional shares, and (ii) $ 0.36 in cash, which we refer to as the Triumph cash consideration, and together with the Triumph stock consideration,

3

the Triumph merger consideration. In the aggregate, Simmons expects to issue approximately 4,164,839 shares of Simmons common stock and pay approximately $ 2,645,937.83 (minus the cash payment for outstanding options to purchase shares of Triumph common stock, which we refer to as Triumph stock options) to Triumph shareholders upon completion of the Triumph merger, subject to certain conditions and potential adjustments under the Triumph merger agreement. The Triumph merger consideration is based on the assumption that (A) 4,586,300 shares of Triumph common stock are issued and outstanding and (B) 148,763 shares of Triumph common stock are subject to outstanding Triumph stock options with a weighted average exercise price of $ 18.67 , in each case, immediately prior to the Triumph effective time. In addition, we have assumed that the Triumph/Simmons average closing price (as described below) is equal to $ 27.49 , which was the closing sales price of Simmons common stock on July 29, 2021, the last practicable trading day prior to printing this proxy statement/prospectus.

Simmons will not issue any fractional shares of Simmons common stock in the Triumph merger. Instead, Triumph shareholders who would otherwise be entitled to a fractional share of Simmons common stock will receive, in lieu thereof, an amount in cash, rounded up to the nearest whole cent (without interest), determined by multiplying (i) the fraction of a share (rounded to the nearest thousandth when expressed in decimal form) of Simmons common stock that such Triumph shareholder would otherwise be entitled to receive by (ii) the average of the daily closing prices of shares of Simmons common stock for the 20 consecutive full trading days on which shares are actually traded on Nasdaq, ending at the close of trading on the tenth business day prior to the Triumph effective time (or the immediately preceding day to the tenth business day prior to the Triumph effective time if shares of Simmons common stock are not actually traded on Nasdaq on such day), which we refer to as the Triumph determination date, and which average we refer to as the Triumph/Simmons average closing price.

If the mergers are both completed, existing Simmons shareholders would own approximately 92.60 % of Simmons common stock immediately following completion of the mergers, while former Triumph shareholders would own approximately 3.56 % and former Landmark shareholders would own approximately 3.84 %. If the Triumph merger is completed, but the Landmark merger is not completed, existing Simmons shareholders and Triumph shareholders would own approximately 96.30 % and 3.70 %, respectively, of Simmons common stock upon completion of the Triumph merger.

| Q: | Will the value of the merger consideration for the Landmark merger or the Triumph merger change between the date of this proxy statement/prospectus and the effective time of the mergers?

| A: | Yes. The amount of merger consideration for the mergers may increase or decrease if the number of fully diluted shares of Landmark common stock or Triumph common stock, as applicable, outstanding changes after the date hereof. Any change in the market price of Simmons common stock prior to the completion of the mergers will affect the market value of the merger consideration that Landmark shareholders and Triumph shareholders will receive upon completion of the respective mergers.

|  | Other than as described in this proxy statement/prospectus, there will be no adjustment to the Landmark merger consideration based upon changes in the market price of Simmons common stock or Landmark common stock prior to the time the Landmark merger is completed, and the Landmark merger agreement cannot be terminated due to a change in the price of Simmons common stock. With respect to the Triumph merger agreement, if, as of the Triumph determination date, (i) the Triumph/Simmons average closing price is greater than $37.28 and (ii) the difference between the percentage change in the Nasdaq Bank Index and the percentage change in the Triumph/Simmons average closing price exceeds 20% over a designated measurement period, the Triumph stock consideration will be adjusted. See the section entitled “The Merger Agreements—The Merger Consideration.” In addition, the Triumph merger agreement

4

can be terminated by Triumph if, at any time during the five-day period commencing on the Triumph determination date, the Triumph/Simmons average closing price is less than $24.85 and the difference between the percentage change in the Nasdaq Bank Index and the percentage change in the Triumph/Simmons average closing price exceeds 20% over a designated measurement period, unless Simmons agrees to increase the Triumph cash consideration by a specified amount. See the section entitled “The Merger Agreements—Termination of the Merger Agreements.”

| Q: | What will Simmons shareholders receive in the mergers?

| A: | If either or both of the mergers are completed, holders of Simmons common stock, or Simmons shareholders, will not receive any merger consideration and will continue to hold the number of shares of Simmons common stock that they currently hold. Following the mergers, shares of Simmons common stock will continue to be traded on Nasdaq under the symbol “SFNC.”

| Q: | How will the mergers affect Landmark and Triumph stock options?

| A: | At the respective effective time, each Landmark stock option and each Triumph stock option, whether vested or unvested, outstanding immediately prior to the Landmark effective time or the Triumph effective time, respectively, and which we refer to collectively as the effective times, will be canceled and converted into the right to receive from Simmons a cash payment equal to the difference, if positive, between (i) the fully diluted per share value (as described below) and (ii) the exercise price of such Landmark stock option or Triumph stock option, as applicable, which we refer to as the Landmark stock option payout and the Triumph stock option payout, respectively.

Fully diluted per share value means with respect to Landmark or Triumph, as applicable, the quotient obtained by dividing (A) the sum of (i) the aggregate cash consideration, (ii) the product of (x) the aggregate stock consideration and (y) the average closing price and (iii) the product of (x) the total number of Landmark stock options or Triumph stock options, as applicable, outstanding immediately prior to the applicable effective time, and (y) the weighted average option exercise price for such stock options by (B) the sum of (i) the total number of shares of Landmark common stock or Triumph common stock, as applicable and (ii) the total number of shares of Landmark common stock or Triumph common stock, as applicable, underlying the Landmark stock options or Triumph stock options, respectively, outstanding, each as of immediately prior to the applicable effective time.

| Q: | When do you expect to complete the mergers?

| A: | Each of Simmons, Landmark and Triumph expect to complete the applicable merger in the fourth quarter of 2021. However, Simmons, Landmark and Triumph cannot assure you of when or if the applicable merger will be completed. Landmark and Triumph must first obtain shareholder approval for the applicable merger, and the parties to the merger agreements also must obtain necessary regulatory approvals and satisfy certain other closing conditions. For further information, see the section entitled “The Merger Agreements—Conditions to Consummation of the Mergers.”

| Q: | How does the Landmark board of directors recommend that Landmark shareholders vote at the Landmark special meeting?

Standard: Approval of the Landmark merger proposal requires the affirmative vote of holders of at least a majority of the outstanding shares of Landmark common stock entitled to vote on the proposal.

A quorum is not required for a vote on the Landmark adjournment proposal.

Effect of abstentions and broker non-votes: If you are a Landmark shareholder and mark “ABSTAIN” on your proxy, it will have the same effect as a vote against the Landmark adjournment proposal. If you fail to submit a proxy or vote in person at the Landmark special meeting, or if you fail to instruct your bank, broker or other nominee how to vote with respect to the Landmark adjournment proposal, it will have no effect on the proposal.

| Q: | Are there any voting agreements with existing Landmark shareholders or Triumph shareholders?

| A: | Yes. In connection with entering into the Landmark merger agreement, each of the directors and certain executive officers of Landmark, in their capacities as individuals, have separately entered into support and non-competition agreements, which we refer to as the Landmark voting agreements, pursuant to which they agreed to vote their beneficially owned shares of Landmark common stock in favor of the Landmark merger proposal and certain related matters and against alternative transactions. In connection with entering into the Triumph merger agreement, each of the directors and certain executive officers of Triumph, in their capacities as individuals, have separately entered into support and non-competition agreements, which we refer to as the Triumph voting agreements, pursuant to which they agreed to vote their beneficially owned shares of Triumph common stock in favor of the Triumph merger proposal and certain related matters and against alternative transactions. As of the Landmark record date, shares constituting approximately 21.54% of the Landmark common stock entitled to vote at the Landmark special meeting are subject to Landmark voting agreements; and as of the Triumph record date, shares constituting

7

approximately 44.49 % of the Triumph common stock entitled to vote at the Triumph special meeting are subject to Triumph voting agreements. For further information, see the section entitled “The Merger Agreements—Voting Agreements.”

| Q: | Why is my vote important?

| A: | If you do not vote, it will be more difficult for Landmark or Triumph to obtain the necessary quorum to hold their respective special meetings. In addition, each proposal must be approved by the voting requirements described above. The Landmark board of directors and the Triumph board of directors unanimously recommend that you vote “FOR” the Landmark merger proposal and “FOR” the Triumph merger proposal, respectively.

| Q: | How many votes do I have?

| A: | Each holder of shares of Landmark common stock outstanding on the Landmark record date, and each holder of shares of Triumph common stock outstanding on the Triumph record date, will be entitled to one vote for each share held of record.

As of the Landmark record date, there were 22,215,981 shares of Landmark common stock outstanding and entitled to vote at the Landmark special meeting. As of the Landmark record date, the directors and executive officers of Landmark and their affiliates beneficially owned and were entitled to vote approximately 4,862,973 shares of Landmark common stock, representing approximately 21.89% of the shares of Landmark common stock outstanding on that date.

As of the Triumph record date, there were 4,586,300 shares of Triumph common stock outstanding and entitled to vote at the Triumph special meeting. As of the Triumph record date, the directors and executive officers of Triumph and their affiliates beneficially owned and were entitled to vote approximately 2,068,694 shares of Triumph common stock, representing approximately 45.11 % of the shares of Triumph common stock outstanding on that date.

|  | Please follow the instructions set forth on the applicable proxy or on the voting instruction form provided by the record holder if your shares are held in “street name” by a bank, broker or other nominee.

| Q: | How do I vote?

| A: | If you hold your shares of Landmark common stock or Triumph common stock in your name as a shareholder of record, you may use one of the following methods to submit a proxy:

| · | by mail by completing, signing, dating and returning the applicable proxy in the enclosed envelope, which requires no additional postage if mailed in the United States; or

| · | in person at the Landmark special meeting or Triumph special meeting, as applicable.

8

|  | If your shares are held in “street name” by a bank, broker or other nominee, that institution will send you separate instructions describing the procedure for voting your shares. You may not vote shares held in “street name” by returning a proxy directly to Landmark or Triumph, as applicable, or by voting at the Landmark special meeting or Triumph special meeting, as applicable, unless you provide a “legal proxy,” which you must obtain from your bank, broker or other nominee.

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

| A: | No. If your shares of Landmark common stock or Triumph common stock are held in “street name” by a bank, broker or other nominee, you must provide the record holder of your shares with instructions on how to vote your shares. Please follow the voting instructions provided by your bank, broker or other nominee. Please note that you may not vote shares held in “street name” by returning a proxy directly to Landmark or Triumph, as applicable, or by voting at the Landmark special meeting or Triumph special meeting, as applicable, unless you provide a “legal proxy,” which you must obtain from your bank, broker or other nominee.

|  | Banks, brokers and other nominees who hold shares of Landmark common stock or Triumph 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 voting discretion with respect to the approval of matters determined to be “non-routine,” without specific instructions from the beneficial owner. Landmark and Triumph expect that all proposals to be voted on at the special meetings will be “non-routine” matters. Broker non-votes are shares held by a bank, broker or other nominee with respect to which such entity 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.

|  | If you are a Landmark shareholder or Triumph shareholder and you do not instruct your bank, broker or other nominee on how to vote your shares:

| · | your bank, broker or other nominee may not vote your shares on the Landmark merger proposal or the Triumph merger proposal, as applicable, which broker non-votes will have the same effect as a vote against such proposal; and

| · | your bank, broker or other nominee may not vote your shares on the Landmark adjournment proposal or the Triumph adjournment proposal, as applicable, which broker non-votes will have no effect on such proposal.

| Q: | What if I abstain or do not vote?

| A: | For purposes of the special meetings, an abstention occurs when a shareholder attends a special meeting, either in person or represented by proxy, but abstains from voting on one or more proposals.

|  | With respect to the Landmark merger proposal or the Triumph merger proposal, if you mark “ABSTAIN” on your proxy, fail to submit a proxy or vote in person at the applicable special meeting, or if you fail to instruct your bank, broker or other nominee how to vote, it will have the same effect as a vote against the applicable merger proposal. With respect to the Landmark adjournment proposal, if you mark “ABSTAIN” on your proxy, it will have the same effect as a vote against the proposal, and if you fail to submit a proxy or vote in person at the Landmark special meeting, or if you fail to instruct your bank, broker or other nominee how to vote, it will have no effect on the proposal. With respect to the Triumph adjournment proposal, if you mark “ABSTAIN” on your proxy, fail to submit a proxy or vote in person at the Triumph special meeting, or if you fail to instruct your bank, broker or other nominee how to vote, it will have no effect on the proposal.

| Q: | What will happen if I return my proxy without indicating how to vote?

| A: | If any proxy is returned without indication as to how to vote, the shares of Landmark common stock or Triumph common stock represented by the proxy will be voted in favor of both the Landmark merger proposal and the Landmark adjournment proposal, in the case of Landmark common stock, or in favor of both the Triumph merger proposal and the Triumph adjournment proposal, in the case of Triumph common stock.

| Q: | Can I attend the Landmark special meeting or the Triumph special meeting and vote my shares in person?

| A: | Yes. All shareholders of Landmark and Triumph, including shareholders of record and shareholders who hold their shares through banks, brokers, nominees or any other holder of record, are invited to attend their respective special meeting. Holders of record of Landmark common stock and Triumph common stock can vote in person at the Landmark special meeting and Triumph special meeting, respectively. If you are not a shareholder of record, you must obtain a proxy, executed in your favor, from the record holder of your shares, such as a broker, bank or other nominee, to be able to vote in person at the applicable special meeting.

| Q: | May I change my vote after I have delivered my proxy?

| A: | Yes. You may change your vote at any time before your proxy is voted at the Landmark special meeting or the Triumph special meeting, as applicable. You may do so in one of three ways:

| · | by completing, signing, dating and returning a proxy with a later date;

| · | by delivering a written revocation letter to Landmark’s head of investor relations or Michael J. McCarver at Triumph, as applicable; or

| · | by voting in person at the applicable special meeting.

|  | If your shares are held in “street name” by a bank, broker or other nominee, you should follow the instructions of your bank, broker or other nominee regarding the revocation of voting instructions.

| Q: | Are Landmark shareholders or Triumph shareholders entitled to dissenters’ rights?

| A: | Landmark shareholders and Triumph shareholders who do not vote in favor of the Landmark merger proposal or the Triumph merger proposal, as applicable, and follow certain procedural steps will be entitled to dissenters’ rights under the provisions of Section 48-23-101 et seq. of the Tennessee Business Corporation Act, or the TBCA. For further information, see the section entitled “The Mergers—Appraisal and Dissenters’ Rights.” In addition, a copy of Section 48-23-101 through Section 48-23-302 of the TBCA is attached as Annex G to this proxy statement/prospectus.

| Q: | What are the material U.S. federal income tax consequences of the Landmark merger to Landmark shareholders and of the Triumph merger to Triumph shareholders?

| A: | Each of the Landmark merger and the Triumph merger is intended to qualify as “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, or the Code. If the Landmark merger and the Triumph merger so qualify, a U.S. holder of Landmark common stock or Triumph common stock, as applicable, receiving a combination of Simmons common stock and cash in exchange for such

10

| Landmark common stock or Triumph common stock will (1) not recognize any loss upon surrendering its Landmark common stock or Triumph common stock and (2) recognize gain upon surrendering its Landmark common stock or Triumph common stock equal to the excess, if any, of (a) the sum of any cash consideration received plus the fair market value (determined as of the effective time of the applicable merger) of the Simmons common stock received over (b) such U.S. holder’s aggregate tax basis in the shares of Landmark common stock or Triumph common stock surrendered, but only to the extent of the amount of any cash consideration received.
| U.S. holders of Landmark common stock or Triumph common stock receiving cash in lieu of fractional shares of Simmons common stock will generally recognize gain or loss equal to the difference between the amount of cash received instead of a fractional share and the basis in its fractional share of Simmons common stock.

|  | For further information, see the section entitled “Material United States Federal Income Tax Consequences of the Mergers.”

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

| Q: | If I am a Landmark shareholder or a Triumph shareholder, should I send in my Landmark or Triumph stock certificates now?

| A: | No. Landmark shareholders and Triumph shareholders SHOULD NOT send in any stock certificates now. If either or both of the mergers are approved by such shareholders, transmittal materials with instructions for their completion will be provided to Landmark shareholders and Triumph shareholders, as applicable, after the Landmark effective time or the Triumph effective time, respectively, and under separate cover and the applicable stock certificates should be sent at that time.

| Q: | What should I do if I hold my shares of Landmark common stock in book-entry form?

| A: | If the Landmark merger occurs, you are not required to take any special additional action to receive the Landmark merger consideration if your shares of Landmark common stock are held in book-entry form. After the completion of the Landmark merger, shares of Landmark common stock held in book-entry form will be exchanged automatically for the Landmark merger consideration, including shares of Simmons common stock in book-entry form, the applicable cash consideration and any cash to be paid in exchange for fractional shares in the Landmark merger.

| Q: | Whom may I contact if I cannot locate my stock certificate(s)?

| A: | Landmark shareholders: If you are unable to locate your original Landmark stock certificate(s), you should contact Deborah R. Fields, telephone: (901) 457-3127, email: lcbinvestorrrelations@landmarkbanktn.com.

|  | Triumph shareholders: If you are unable to locate your original Triumph stock certificate(s), you should contact Katie Hargett at 5699 Poplar Avenue, Memphis, Tennessee 38119, telephone: (901) 333-8852, email: katie.hargett@triumphbank.com.

| Q: | What should I do if I receive more than one set of voting materials?

| A: | Landmark shareholders and Triumph shareholders may receive more than one set of voting materials, including multiple copies of this proxy statement/prospectus and multiple proxies or voting instruction cards. For example, if you hold shares of Landmark common stock or Triumph common stock in more than one brokerage account, you will receive a separate voting instruction card for each brokerage account in which you hold such shares. If you are a holder of record of Landmark common stock or Triumph common stock and your shares are registered in more than one name, you will receive more than one proxy. In addition, if you are a holder of both Landmark common stock and Triumph common stock, you will receive one or more separate proxies or voting instruction cards for each company. Please complete, sign, date and return each proxy and voting instruction card that you receive or otherwise follow the voting instructions set forth in this proxy statement/prospectus to ensure that you vote every share of Landmark common stock and/or Triumph common stock that you own.

| Q: | What happens if I sell my shares of Landmark common stock or Triumph common stock after the applicable record date but before the applicable special meeting?

| A: | The Landmark record date and the Triumph record date are earlier than the date of the Landmark special meeting and the Triumph special meeting, respectively, and earlier than the date that the mergers are expected to be completed. If you transfer your shares of Landmark common stock or Triumph common stock after the applicable record date but before the date of the applicable special meeting, you will retain your right to vote at such special meeting (provided that such shares remain outstanding on the date of such special meeting), but you will not have the right to receive any applicable merger consideration for the transferred shares of Landmark common stock or Triumph common stock. You will only be entitled to receive the applicable merger consideration in respect of shares of Landmark common stock or Triumph common stock, as applicable, that you hold at the Landmark effective time or the Triumph effective time, respectively.

| Q: | Are there risks involved in undertaking the mergers?

| A: | Yes. You should read and carefully consider the risk factors set forth in the section entitled “Risk Factors” beginning on page 32 of this proxy statement/prospectus.

| Q: | What happens if the mergers are not completed?

| A: | If either or both of the mergers are not completed, holders of Landmark common stock or Triumph common stock, as applicable, will not receive any merger consideration for their shares in connection with the applicable merger. Instead, Landmark, Triumph or both will remain an independent company. In addition, if either or both of the merger agreements are terminated in certain circumstances, a termination fee may be required to be paid to Simmons by Landmark or Triumph, as applicable. See the section entitled “The Merger Agreements—Termination Fees” for a discussion of the circumstances under which termination fees will be required to be paid.

The Landmark Merger (page 56)

Terms of the Landmark Merger (page 56)

The terms and conditions of the Landmark merger are contained in the Landmark merger agreement, which is attached to this proxy statement/prospectus as Annex A. We urge you to read the Landmark merger agreement carefully and in its entirety, as it is the legal document governing the Landmark merger. All descriptions in this summary and elsewhere in this proxy statement/prospectus of the terms and conditions of the Landmark merger are subject to, and qualified in their entirety by reference to, the Landmark merger agreement.

Under the terms and subject to the conditions of the Landmark merger agreement, among other things, Landmark will merge with and into Simmons Bank, with Simmons Bank as the surviving bank in the Landmark merger.

Based on the assumptions set forth below, at the Landmark effective time, each share of Landmark common stock that is issued and outstanding immediately prior to the Landmark effective time, excluding certain specified shares, will be converted into the right to receive, subject to possible adjustment, (i) approximately 0.2025 shares of Simmons common stock, with cash in lieu of fractional shares, and (ii) $0.29 in cash. In the aggregate, Simmons expects to issue approximately 4,500,000 shares of Simmons common stock and pay approximately $7,000,000 (minus the cash payment for outstanding Landmark stock options) to Landmark shareholders upon completion of the Landmark merger, subject to certain conditions and potential adjustments under the Landmark merger agreement. The Landmark merger consideration is based on the assumption that (i) 22,215,981 shares of Landmark common stock are issued and outstanding and (ii) 218,400 shares of Landmark common stock are subject to outstanding Landmark stock options with a weighted average exercise price of $3.49, in each case, immediately prior to the Landmark effective time. In addition, we have assumed that the Landmark/Simmons average closing price is equal to $27.49, which was the closing sales price of Simmons common stock on July 29, 2021, the last practicable trading day prior to printing this proxy statement/prospectus.

Simmons will not issue any fractional shares of Simmons common stock in the Landmark merger. Instead, a Landmark shareholder who would otherwise be entitled to a fractional share of Simmons common stock upon the completion of the Landmark merger will receive, in lieu thereof, an amount in cash, rounded up to the nearest whole cent (without interest), determined by multiplying (i) the fraction of a share (rounded to the nearest thousandth when expressed in decimal form) of Simmons common stock that such Landmark shareholder would otherwise be entitled to receive by (ii) the Landmark/Simmons average closing price.

The market value of the Landmark merger consideration will fluctuate with the price of Simmons common stock, and at the time of the Landmark special meeting, Landmark shareholders will not know or be able to calculate the value of the Landmark merger consideration to be received upon completion of the Landmark merger. Other than as described in this proxy statement/prospectus, there will be no adjustment to the Landmark merger consideration based upon changes in the market price of Simmons common stock or Landmark common stock prior to the time the Landmark merger is completed, and the Landmark merger agreement cannot be

15

terminated due to a change in the price of Simmons common stock. For further information, see the section entitled “The Merger Agreements—The Merger Consideration.”

Based on the closing sale price per share of Simmons common stock on June 4, 2021, the last trading day before the public announcement of the signing of the Landmark merger agreement, and on July 29 , 2021, the last practicable trading day prior to printing this proxy statement/prospectus, and on certain assumptions as described elsewhere in this proxy statement/prospectus, the implied value of the aggregate Landmark merger consideration payable is approximately $146,320,000.00, or $6.56 per share of Landmark common stock, and approximately $130,705,000.00, or $5.86 per share of Landmark common stock, respectively (such per share amounts exclude the cash payment for outstanding stock options of Landmark) .

Treatment of Equity Awards—Landmark Stock Options (page 104)

At the Landmark effective time, each Landmark stock option, whether vested or unvested, outstanding immediately prior to the Landmark effective time, will be canceled and converted into the right to receive from Simmons a cash payment equal to the difference, if positive, between (1) the fully diluted per share value and (2) the exercise price of such Landmark stock option, which we refer to as the Landmark stock option payout. Any such Landmark stock option with an exercise price per share that equals or exceeds the amount set forth in (1) will be canceled with no consideration paid to the optionholder less any required withholding for taxes.

Landmark’s Reasons for the Landmark Merger and Recommendation of the Landmark Board of Directors (page 59)

The Landmark board of directors has approved the Landmark merger agreement and recommends that Landmark shareholders vote “FOR” the Landmark merger proposal and, if necessary or appropriate, “FOR” the adjournment proposal. See the section entitled “The Landmark Merger—Landmark’s Reasons for the Landmark Merger and Recommendation of the Landmark Board of Directors” for a more detailed discussion of the factors considered by the Landmark board of directors in reaching its decision to approve the Landmark merger agreement and the transactions contemplated thereby.

Opinion of Landmark’s Financial Advisor (page 61)

In connection with the Landmark merger, Landmark’s financial advisor, Olsen Palmer LLC, which we refer to as Olsen Palmer, delivered a written opinion, dated June 4, 2021, to the Landmark board of directors as to the fairness, from a financial point of view and as of the date of the opinion, to the holders of Landmark common stock of the Landmark merger consideration. The full text of the opinion, which describes the procedures followed, assumptions made, matters considered, and qualifications and limitations on the review undertaken by Olsen Palmer in preparing the opinion, is attached as Annex E to this proxy statement/prospectus.

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

For a description of the Olsen Palmer opinion, see the section entitled “The Landmark Merger—Opinion of Landmark’s Financial Advisor.”

Simmons’ Reasons for the Landmark Merger (page 70)

The Simmons board of directors adopted and approved the Landmark merger agreement. See the section entitled “The Landmark Merger—Simmons’ Reasons for the Landmark Merger” for a more detailed discussion of the factors considered by the Simmons board of directors in reaching its decision to approve the Landmark merger agreement, including the Landmark merger and all transactions contemplated thereby.

The Landmark Special Meeting (page 41)

The Landmark special meeting will be held on September 7 , 2021, at 6:00 p.m. Central Time, at the Hunt & Polo Club, 650 Shady Grove Road, Memphis, Tennessee 38120 . At the Landmark special meeting, Landmark shareholders will be asked to consider and vote on the Landmark merger proposal and, if necessary or appropriate, the Landmark adjournment proposal.

Landmark has set the close of business on July 29 , 2021 as the Landmark record date to determine which Landmark shareholders will be entitled to receive notice of and vote at the Landmark special meeting. Each holder of shares of Landmark common stock outstanding on the Landmark record date will be entitled to one vote for each share held of record. As of the Landmark record date, there were 22,215,981 shares of Landmark common stock outstanding and entitled to vote at the Landmark special meeting. As of the Landmark record date, the directors and executive officers of Landmark and their affiliates beneficially owned and were entitled to vote approximately 4,862,973 shares of Landmark common stock, representing approximately 21.89% of the shares of Landmark common stock outstanding on that date.

Approval of the Landmark merger proposal requires the affirmative vote of holders of at least a majority of the outstanding shares of Landmark common stock entitled to vote on the Landmark merger proposal. Approval of the adjournment proposal requires the affirmative vote of holders of at least a majority of the outstanding shares of Landmark common stock present or represented by proxy at the Landmark special meeting and entitled to vote on the Landmark adjournment proposal. A quorum is not required for a vote on the Landmark adjournment proposal.

With respect to the Landmark merger proposal, if you mark “ABSTAIN” on your proxy, fail to submit a proxy or vote in person at the Landmark special meeting, or if you fail to instruct your bank, broker or other nominee how to vote, it will have the same effect as a vote against the proposal. With respect to the Landmark adjournment proposal, if you mark “ABSTAIN” on your proxy, it will have the same effect as a vote against the proposal, and if you fail to submit a proxy or vote in person at the Landmark special meeting, or if you fail to instruct your bank, broker or other nominee how to vote, it will have no effect on the proposal.

Interests of Landmark’s Directors and Executive Officers in the Landmark Merger (page 72)

In considering the recommendation of the Landmark board of directors that Landmark shareholders vote “FOR” the Landmark merger proposal, Landmark shareholders should be aware that some of Landmark’s executive officers and directors have interests in the Landmark merger, which may be considered to be different from, or in addition to, the interests of the Landmark shareholders generally. The Landmark board of directors was aware of these interests and considered them, among other matters, in reaching its decision to approve the Landmark merger agreement, the Landmark merger and the other transactions contemplated by the Landmark merger agreement and to recommend that Landmark shareholders vote “FOR” the Landmark merger proposal.

These interests are described in more detail in the section entitled “The Landmark Merger—Interests of Landmark’s Directors and Executive Officers in the Landmark Merger.”

The Triumph Merger (page 74)

Terms of the Triumph Merger (page 74)

The terms and conditions of the Triumph merger are contained in the Triumph merger agreement, which is attached to this proxy statement/prospectus as Annex B. We urge you to read the Triumph merger agreement carefully and in its entirety, as it is the legal document governing the Triumph merger. All descriptions in this summary and elsewhere in this proxy statement/prospectus of the terms and conditions of the Triumph merger are subject to, and qualified in their entirety by reference to, the Triumph merger agreement.

Under the terms and subject to the conditions of the Triumph merger agreement, among other things, Triumph will merge with and into Simmons, with Simmons as the surviving corporation in the Triumph merger. Immediately following the Triumph merger, Triumph Bank will merge with and into Simmons Bank, with Simmons as the surviving bank.

Based on the assumptions set forth below, at the Triumph effective time, each share of Triumph common stock that is issued and outstanding immediately prior to the Triumph effective time, excluding certain specified shares, will be converted into the right to receive, subject to possible adjustment, (i) approximately 0.9081 shares of Simmons common stock, with cash in lieu of fractional shares, and (ii) $ 0.36 in cash. In the aggregate, Simmons expects to issue approximately 4,164,839 shares of Simmons common stock and pay approximately $ 2,645,937.83 (minus the cash payment for outstanding Triumph stock options) to Triumph shareholders upon completion of the Triumph merger, subject to certain conditions and potential adjustments under the Triumph merger agreement. The Triumph merger consideration is based on the assumption that (i) 4,586,300 shares of Triumph common stock are issued and outstanding and (ii) 148,763 shares of Triumph common stock are subject to outstanding Triumph stock options with a weighted average exercise price of $ 18.67 , in each case, immediately prior to the Triumph effective time. In addition, we have assumed that the Triumph/Simmons average closing price is equal to $27.49, which was the closing sales price of Simmons common stock on July 29, 2021, the last practicable trading day prior to printing this proxy statement/prospectus.

Simmons will not issue any fractional shares of Simmons common stock in the Triumph merger. Instead, a Triumph shareholder who would otherwise be entitled to a fractional share of Simmons common stock upon the completion of the Triumph merger will receive, in lieu thereof, an amount in cash, rounded up to the nearest whole cent (without interest), determined by multiplying (i) the fraction of a share (rounded to the nearest thousandth when expressed in decimal form) of Simmons common stock that such Triumph shareholder would otherwise be entitled to receive by (ii) the Triumph/Simmons average closing price.

The market value of the Triumph merger consideration will fluctuate with the price of Simmons common stock, and at the time of the Triumph special meeting, Triumph shareholders will not know or be able to calculate the value of the Triumph merger consideration to be received upon completion of the Triumph merger. If, as of the Triumph determination date, (i) the Triumph/Simmons average closing price is greater than $37.28 and (ii) the difference between the percentage change in the Nasdaq Bank Index and the percentage change in the Triumph/Simmons average closing price exceeds 20% over a designated measurement period, the Triumph stock consideration will be adjusted. See the section entitled “The Merger Agreements—The Merger Consideration.” In addition, the Triumph merger agreement can be terminated by Triumph if, at any time during the five-day period commencing on the Triumph determination date, the Triumph/Simmons average closing price is less than $24.85 and the difference between the percentage change in the Nasdaq Bank Index and the percentage change in the Triumph/Simmons average closing price exceeds 20% over a designated measurement period, unless Simmons agrees to increase the Triumph cash consideration by a specified amount.”

Based on the closing sale price per share of Simmons common stock on June 4, 2021, the last trading day before the public announcement of the signing of the Triumph merger agreement, and on July 29 , 2021, the last

18

practicable trading day prior to printing this proxy statement/prospectus, and on certain assumptions as described elsewhere in this proxy statement/prospectus, the implied value of the aggregate Triumph merger consideration payable for each share of Triumph common stock is approximately $ 131,589,353.27 , or $ 28.38 per share of Triumph common stock, and approximately $ 117,137,361.94 , or $ 25.32 per share of Triumph common stock, respectively (such per share amounts exclude the cash payment for outstanding stock options of Triumph) .

Treatment of Equity Awards—Triumph Stock Options (page 104)

At the Triumph effective time, each Triumph stock option, whether vested or unvested, outstanding immediately prior to the Triumph effective time, will be canceled and converted into the right to receive from Simmons a cash payment equal to the difference, if positive, between (1) the fully diluted per share value and (2) the exercise price of such Triumph stock option, which we refer to as the Triumph stock option payout. Any such Triumph stock option with an exercise price per share that equals or exceeds the amount set forth in (1) will be canceled with no consideration paid to the optionholder less any required withholding for taxes.

Triumph’s Reasons for the Triumph Merger and Recommendation of the Triumph Board of Directors (page 78)

The full text of the opinion, which describes the procedures followed, assumptions made, matters considered, and qualifications and limitations on the review undertaken by Southard Financial in preparing the opinion, is attached as Annex F to this proxy statement/prospectus.

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

At the Triumph special meeting, Triumph shareholders will be asked to consider and vote on the Triumph merger proposal and, if necessary or appropriate, the Triumph adjournment proposal.

Triumph has set the close of business on August 2, 2021 as the Triumph record date to determine which Triumph shareholders will be entitled to receive notice of and vote at the Triumph special meeting. Each holder of shares of Triumph common stock outstanding on the Triumph record date will be entitled to one vote for each share held of record. As of the Triumph record date, there were 4,586,300 shares of Triumph common stock outstanding and entitled to vote at the Triumph special meeting. As of the Triumph record date, the directors and executive officers of Triumph and their affiliates beneficially owned and were entitled to vote approximately 2,068,694 shares of Triumph common stock, representing approximately 45.11 % of the shares of Triumph common stock outstanding on that date.

Approval of the Triumph merger proposal requires the affirmative vote of holders of at least a majority of the outstanding shares of Triumph common stock entitled to vote on the Triumph merger proposal. Approval of the Triumph adjournment proposal requires the votes cast by the outstanding shares of Triumph common stock present or represented by proxy at the Triumph special meeting and entitled to vote on the proposal favoring the approval to exceed the votes cast opposing the approval. A quorum is not required for a vote on the Triumph adjournment proposal.

With respect to the Triumph merger proposal, if you mark “ABSTAIN” on your proxy, fail to submit a proxy or vote in person at the Triumph special meeting, or if you fail to instruct your bank, broker or other nominee how to vote, it will have the same effect as a vote against the proposal. With respect to the Triumph adjournment proposal, if you mark “ABSTAIN” on your proxy, fail to submit a proxy or vote in person at the Triumph special meeting, or if you fail to instruct your bank, broker or other nominee how to vote, it will have no effect on the proposal.

Interests of Triumph’s Directors and Executive Officers in the Triumph Merger (page 92)

In considering the recommendation of the Triumph board of directors that Triumph shareholders vote “FOR” the Triumph merger proposal, Triumph shareholders should be aware that some of Triumph’s executive officers and directors have interests in the Triumph merger, which may be considered to be different from, or in addition to, the interests of the Triumph shareholders generally. The Triumph board of directors was aware of these interests and considered them, among other matters, in reaching its decision to approve the Triumph merger agreement, the Triumph merger and the other transactions contemplated by the Triumph merger agreement and to recommend that Triumph shareholders vote “FOR” the Triumph merger proposal.

These interests are described in more detail in the section entitled “The Triumph Merger—Interests of Triumph’s Directors and Executive Officers in the Triumph Merger.”

Public Trading Markets (page 95)

Simmons common stock is listed on Nasdaq under the symbol “SFNC.” The Simmons common stock issuable in the mergers will be listed on Nasdaq.

Accounting Treatment (page 95)

The mergers will be accounted for as acquisitions by Simmons using the acquisition method of accounting in accordance with FASB ASC Topic 805, “Business Combinations.” The result of this is that (1) the recorded assets and liabilities of Simmons will be carried forward at their recorded amounts, (2) Simmons historical operating results will be unchanged for the prior periods being reported on, and (3) the assets and liabilities of each of Landmark and Triumph will be adjusted to fair value at the respective dates Simmons assumes control of the combined entity, or the respective merger dates. In addition, all identifiable intangibles will be recorded at fair value and included as part of the net assets acquired. The amount by which the purchase price for each merger, consisting of the value of cash and shares of Simmons common stock to be issued to former Landmark shareholders and Triumph shareholders, respectively, and the value of cash and shares of Simmons common stock to be issued to former holders of Landmark and Triumph equity awards, respectively, exceeds the fair value of the net assets, including identifiable intangibles, of Landmark and Triumph, respectively, at the applicable merger date will be reported as goodwill. In accordance with current accounting guidance, goodwill is not amortized and will be evaluated for impairment at least annually. Identified intangibles will be amortized over their estimated lives. Further, the acquisition method of accounting results in the operating results of each of Landmark and Triumph being included in the operating results of Simmons from the applicable merger date going forward.

Appraisal and Dissenters’ Rights (page 95)

Landmark shareholders and Triumph shareholders who do not vote in favor of the applicable merger proposal and follow certain procedural steps will be entitled to dissenters’ rights under the provisions of Section 48-23-101 et seq. of the TBCA. These procedural steps include, among others: (1) delivering to Landmark or Triumph, as applicable, before the vote at the applicable special meeting is taken, written notice of such shareholder’s intent to demand payment for such shareholder’s shares of Landmark common stock or Triumph common stock if the applicable merger is effectuated, (2) not voting, or causing or permitting to be voted, such shareholder’s shares of Landmark common stock or Triumph common stock in favor of the applicable merger and (3) demanding payment and depositing with Simmons such shareholder’s stock certificates representing such holder’s shares of Landmark common stock or Triumph common stock, as applicable, in accordance with the terms of the written dissenters’ notice sent by Simmons following the applicable merger, which notice will set forth where and when to send the payment demand.

For more information, see the section entitled “The Mergers—Appraisal and Dissenters’ Rights.”

Regulatory Approvals Required for the Mergers and the Triumph Bank Merger (page 99)

The completion of the mergers and the Triumph Bank merger are subject to prior receipt of certain approvals and consents required to be obtained from, or waived by, applicable governmental and regulatory authorities. These approvals include approvals from, among others, the Board of Governors of the Federal Reserve System, or the Federal Reserve Board, the Tennessee Department of Financial Institutions, or the TDFI, and the Arkansas State Bank Department, or the ASBD. Simmons, Landmark and Triumph have agreed to use their reasonable best efforts and cooperate to promptly prepare and file all necessary documentation and to obtain as promptly as practicable all regulatory approvals necessary or advisable to complete the transactions contemplated by the merger agreements. Although Simmons, Landmark and Triumph believe that the mergers do not raise significant regulatory concerns and that they will be able to obtain all requisite regulatory approvals, none of Simmons, Landmark or Triumph can assure you that all of the regulatory approvals described above will be obtained and, if

21

obtained, cannot assure you as to the timing of any such approvals, the parties’ ability to obtain the approvals on satisfactory terms or the absence of any litigation challenging such approvals.

| o | (a) any regulatory authority denies a requisite regulatory approval, and such denial has become final, or has advised any party that it will not grant (or intends to rescind or revoke if previously approved) a requisite regulatory approval or (b) any regulatory authority shall have requested that Simmons, Simmons Bank, Landmark or Triumph, as applicable, or any of their respective affiliates withdraw (other than for technical reasons), and not be permitted to resubmit within 60 days, any application with respect to a requisite regulatory approval, unless in each case the failure to obtain the requisite regulatory approval shall be due to the failure of the party seeking to terminate the applicable merger agreement to perform or observe the obligations, covenants and agreements of such party under such merger agreement;

Termination Fees (page 123)

Landmark and Triumph, as applicable, will pay Simmons a termination fee of $7,000,000 and $6,500,000, respectively, if:

| · | (1) any party to the applicable merger agreement effects an outside date termination or a no-vote termination, or (2) Simmons effects a breach termination and, in each case, within 12 months of such termination, Landmark or Triumph, as applicable, consummates an acquisition transaction or enters into an acquisition agreement with respect to an acquisition transaction, whether or not such acquisition transaction is subsequently consummated; or

| · | Simmons or Simmons Bank, as applicable, effects a board breach termination.

Voting Agreements (page 124)

In connection with entering into the Landmark merger agreement, each of the directors and certain executive officers of Landmark, in their capacities as individuals, have separately entered into Landmark voting agreements, pursuant to which they agreed to vote their beneficially owned shares of Landmark common stock in favor of the Landmark merger proposal and certain related matters and against alternative transactions. In connection with entering into the Triumph merger agreement, each of the directors and certain executive officers of Triumph, in their capacities as individuals, have separately entered into Triumph voting agreements, pursuant to which they agreed to vote their beneficially owned shares of Triumph common stock in favor of the Triumph merger proposal and certain related matters and against alternative transactions. As of the Landmark record date, shares constituting approximately 21.54% of the Landmark common stock entitled to vote at the Landmark special meeting are subject to Landmark voting agreements; and as of the Triumph record date, shares constituting approximately 44.49 % of the Triumph common stock entitled to vote at the Triumph special meeting are subject to Triumph voting agreements. For further information, see the section entitled “The Merger Agreements—Voting Agreements.”

Material United States Federal Income Tax Consequences of the Mergers (page 126)

The respective obligations of Simmons and Landmark to complete the Landmark merger are contingent upon Simmons and Landmark receiving a legal opinion from Covington that the Landmark merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code. Similarly, the respective obligations of Simmons and Triumph to complete the Triumph merger are conditioned upon Simmons and Triumph receiving a legal opinion from Covington to the effect that the Triumph merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code. None of Simmons, Landmark or Triumph currently intends to waive this condition to the consummation of the Landmark merger or the Triumph merger, as applicable. If any party waives this condition after this registration statement is declared effective by the SEC, and if the tax consequences of the Landmark merger to Landmark shareholders or the Triumph merger to Triumph shareholders have materially changed, Simmons and Landmark or Triumph, as applicable, will recirculate appropriate soliciting materials to resolicit the votes of Landmark shareholders or Triumph shareholders.

Each of the Landmark merger and the Triumph merger is intended to qualify as “reorganization” within the meaning of Section 368(a) of the Code. If the Landmark merger and the Triumph merger so qualify, a U.S. holder of Landmark common stock or Triumph common stock, respectively, receiving a combination of Simmons common stock and cash in exchange for such Landmark common stock or Triumph common stock will (1) not

26

recognize any loss upon surrendering its Landmark common stock or Triumph common stock and (2) recognize gain upon surrendering its Landmark common stock or Triumph common stock equal to the excess, if any, of (a) the sum of any cash consideration received plus the fair market value (determined as of the effective time of the applicable merger) of the Simmons common stock received over (b) such U.S. holder’s aggregate tax basis in the shares of Landmark common stock or Triumph common stock surrendered, but only to the extent of the amount of any cash consideration received.

U.S. holders of Landmark common stock or Triumph common stock receiving cash in lieu of fractional shares of Simmons common stock will generally recognize gain or loss equal to the difference between the amount of cash received instead of a fractional share and the basis in its fractional share of Simmons common stock.

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

Comparison of Shareholders’ Rights of Simmons and Landmark, and Simmons and Triumph (pages 129 and 143)

The rights of Landmark shareholders are currently governed by the charter of Landmark, as amended, which we refer to as the Landmark charter, and the bylaws of Landmark, which we refer to as the Landmark bylaws. The rights of Triumph are currently governed by the amended and restated charter of Triumph, as amended, which we refer to as the Triumph charter, and the amended and restated bylaws of Triumph, as amended, which we refer to as the Triumph bylaws. Upon completion of the mergers, the rights of former holders of Landmark common stock and Triumph common stock will be governed by the amended and restated articles of incorporation of Simmons, which we refer to as the Simmons charter, and the As Amended By-Laws of Simmons, which we refer to as the Simmons bylaws. Simmons is organized under Arkansas law, while Landmark and Triumph are organized under Tennessee law. The rights associated with Landmark common stock and Triumph common stock are different from the rights associated with Simmons common stock. See the sections entitled “Comparison of Shareholders’ Rights of Simmons and Landmark” and “Comparison of Shareholders’ Rights of Simmons and Triumph” for a discussion of the different rights associated with Simmons common stock.

MARKET PRICE AND DIVIDENDS

Simmons common stock trades on Nasdaq under the symbol “SFNC.” Neither Landmark nor Triumph common stock is listed on a public exchange. As of July 30 , 2021 there were approximately 2,174 registered Simmons shareholders , as of July 29, 2021, there were approximately 256 Landmark shareholders of record and as of August 2, 2021 there were approximately 276 Triumph shareholders of record. There is no established public trading market for Landmark common stock or Triumph common stock. Shares of Landmark common stock and Triumph common stock are sold from time to time in isolated transactions that are privately negotiated between the purchasers and the sellers of such shares. If sales do occur, they are not subject to any reporting system. Shares of Landmark common stock and Triumph common stock are not traded frequently and the prices at which transactions involving such shares have occurred may not necessarily reflect the price that would be paid for Landmark common stock or Triumph common stock in an active market. The management of Landmark is aware of the following separate, isolated transactions: (i) in the third quarter of 2019, a total of 14,098 shares of Landmark common stock were transferred in three transactions at prices ranging from $5.10 to $5.30 per share; (ii) in the fourth quarter of 2019, a total of 36,283 shares of Landmark common stock were transferred in six transactions at prices ranging from $5.00 to $5.60 per share; (iii) in the second quarter of 2020, 7,000 shares of Landmark common stock were transferred at a price of $5.40 per share; (iv) in the fourth quarter of 2020, a total of 45,300 shares of Landmark common stock were transferred in three transactions at prices ranging from $5.00 to $5.40 per share; (v) in the first quarter of 2021, a total of 28,796 shares of Landmark common stock were transferred in three transactions at prices ranging from $5.10 to $5.40 per share; and (vi) in the second quarter of 2021, a total of 20,000 shares of Landmark common stock were transferred in two transactions at a price of $5.25 per share. Because there have been no recent private sales of Triumph common stock of which Simmons or Triumph is aware, no recent price data regarding Triumph common stock is available.

Landmark has a history of paying semi-annual cash dividends on Landmark common stock and intends to continue to pay such dividends in the future; however, there can be no assurance with respect to the amount, if any, of dividends that might be declared and paid in the future. Triumph does not regularly pay dividends on Triumph common stock and there can be no assurance with respect to the amount, if any, of dividends that might be declared and paid in the future.

The following table sets forth the closing sale price per share of Simmons common stock as reported on Nasdaq on June 4, 2021, the last trading day before the public announcement of the signing of the Landmark merger agreement and the Triumph merger agreement, and on July 29 , 2021, the last practicable trading day prior to printing this proxy statement/prospectus. The table also shows (i) the applicable cash consideration payable for each share of Landmark common stock and Triumph common stock, (ii) the implied value of the applicable stock consideration payable for each share of Landmark common stock and Triumph common stock on June 4, 2021 and July 29 , 2021, the last practicable trading day prior to printing this proxy statement/prospectus and (iii) the implied value of the Landmark merger consideration and Triumph merger consideration, in each case using the assumptions described in this proxy statement/prospectus (such per share amounts exclude the cash payment for outstanding stock options of each of Landmark and Triumph) .

|  | Simmons Common Stock |  |  | Cash Consideration Per Share of Landmark Common Stock |  |  | Implied Value of Stock Consideration Per Share of Landmark Common Stock |  |  | Implied Value of Per Share Landmark Merger Consideration |

We urge you to obtain current market quotations for Simmons common stock. The market value of the Landmark merger consideration and the Triumph merger consideration will fluctuate with the price of Simmons common stock. At the time of the special meetings of Landmark shareholders and Triumph shareholders, the Landmark shareholders and Triumph shareholders will not know or be able to calculate the value of the applicable merger consideration to be received upon completion of the Landmark merger or the Triumph merger, respectively.

RISK FACTORS

In addition to general investment risks and the other information contained in or incorporated by reference into this proxy statement/prospectus, including the matters addressed in the section entitled “Cautionary Statement Regarding Forward-Looking Statements,” and the matters discussed under the captions “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” sections of Simmons’ Annual Report on Form 10-K for the year ended December 31, 2020 and any updates to those risk factors set forth in Simmons’ Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and other filings, which have been filed with the SEC, Landmark shareholders and Triumph shareholders should carefully consider the following factors in deciding whether to vote for the proposals presented in this proxy statement/prospectus. See also the section entitled “Where You Can Find More Information.”

Risks Relating to the Mergers

Because the market price of Simmons common stock will fluctuate, the value of the Landmark stock consideration to be received by Landmark shareholders and the value of the Triumph stock consideration to be received by Triumph shareholders is uncertain.

Based on the assumptions set forth herein, upon completion of the Landmark merger, each share of outstanding Landmark common stock (except for shares of Landmark common stock held directly or indirectly by Landmark or Simmons and any dissenting shares) will be converted into the right to receive the Landmark stock consideration, with cash paid in lieu of any remaining fractional shares, and the Landmark cash consideration. Based on the assumptions set forth herein, upon completion of the Triumph merger, each share of outstanding Triumph common stock (except for shares of Triumph common stock held directly or indirectly by Triumph or Simmons and any dissenting shares) will be converted into the right to receive the Triumph stock consideration, with cash paid in lieu of any remaining fractional shares, and the Triumph cash consideration. Any change in the market price of Simmons common stock prior to the completion of the mergers will affect the market value of the Landmark stock consideration and the Triumph stock consideration that Landmark shareholders and Triumph shareholders, respectively, will receive upon completion of the applicable merger. At the time of the Landmark special meeting and the Triumph special meeting, you will not know or be able to calculate the value of the Simmons common stock that you will receive upon completion of the applicable merger. Stock price changes may result from a variety of factors, including general market and economic conditions, changes in the respective businesses, operations and prospects of Simmons, Landmark or Triumph, and regulatory considerations, among other things. Many of these factors are beyond the control of Simmons, Landmark and Triumph. You should obtain current market quotations for shares of Simmons common stock before voting your shares at the applicable special meeting.

Other than as described in this proxy statement/prospectus, there will be no adjustment to the Landmark merger consideration based upon changes in the market price of Simmons common stock or Landmark common stock prior to the time the Landmark merger is completed, and the Landmark merger agreement cannot be terminated due to a change in the price of Simmons common stock. The Triumph stock consideration will be adjusted if the Triumph/Simmons average closing price is greater than $37.28 and the difference between the percentage change in the Nasdaq Bank Index and the percentage change in the Triumph/Simmons average closing price exceeds 20% over a designated measurement period. See the section entitled “The Merger Agreements—The Merger Consideration.” In addition, the Triumph merger agreement can be terminated by Triumph if, at any time during the five-day period commencing on the Triumph determination date, the Triumph/Simmons average closing price is less than $24.85 and the difference between the percentage change in the Nasdaq Bank Index and the percentage change in the Triumph/Simmons average closing price exceeds 20% over a designated measurement period, unless Simmons agrees to increase the Triumph cash consideration by a specified amount. See the section entitled “The Merger Agreements—Termination of the Merger Agreements.”

32

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

Before either merger may be completed, various approvals must be obtained from bank regulatory authorities. In determining whether to grant these approvals, the applicable regulatory authorities consider a variety of factors, including the competitive impact of the applicable proposal in the relevant geographic markets; financial, managerial and other supervisory considerations, including the future prospects, of each party; potential effects of the applicable merger on the convenience and needs of the communities to be served and the record of the insured depository institutions under the Community Reinvestment Act of 1977 and the regulations promulgated thereunder, or the Community Reinvestment Act, including the insured depository institutions’ respective overall compliance records and recent fair lending examinations; effectiveness of the parties in combatting money laundering activities; the extent to which the applicable proposal would result in greater or more concentrated risks to the stability of the United States banking or financial system; and whether Simmons controls or would after consummation of the applicable merger control deposits in excess of certain limits. These regulatory authorities 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 completion of either merger or of imposing additional costs or limitations on the combined company following either merger. The regulatory approvals may not be received at all, may not be received in a timely fashion, or may contain conditions on the completion of either merger that are not anticipated or cannot be met. Furthermore, such conditions or changes may constitute a burdensome condition that may allow Simmons to terminate either merger agreement and if so, Simmons may exercise its right to terminate either merger agreement. If the consummation of either merger is delayed, including by a delay in receipt of necessary regulatory approvals, the business, financial condition and results of operations of each party to the applicable merger may also be materially and adversely affected. See the section entitled “The Mergers—Regulatory Approvals Required for the Mergers and the Triumph Bank Merger.”

Failure of either merger to be completed, the termination of either merger agreement or a significant delay in the consummation of either merger could negatively impact Simmons and Landmark or Triumph, as applicable.

Each merger agreement is subject to a number of conditions which must be fulfilled in order to complete the applicable merger. Please see the section entitled “The Merger Agreements—Conditions to Consummation of the Mergers.” These conditions to the consummation of the mergers may not be fulfilled and, accordingly, either merger may not be completed. In addition, if either the Landmark merger or Triumph merger is not completed by March 1, 2022, either Simmons or Landmark, in the case of the Landmark merger, and either Simmons or Triumph, in the case of the Triumph merger, may choose to terminate the applicable merger agreement at any time after such date if the failure to consummate the transactions contemplated by such merger agreement is not caused by any breach of such merger agreement by the party electing to terminate such merger agreement, before or after shareholder approval of the applicable merger.

If either merger is not consummated, the ongoing business, financial condition and results of operations of each party may be materially adversely affected and the market price of Simmons common stock may decline significantly, particularly to the extent that the current market price reflects a market assumption that the mergers will be consummated. If the consummation of either merger is delayed, including by the receipt of a competing acquisition proposal, the business, financial condition and results of operations of each party may be materially adversely affected.

In addition, each party to the mergers has incurred and will incur substantial expenses in connection with the negotiation and completion of the transactions contemplated by the applicable merger agreement, as well as the costs and expenses of filing, printing and mailing this proxy statement/prospectus and all filing and other fees paid to the SEC and other regulatory agencies in connection with the applicable merger. If either merger is not completed, the parties would have to recognize these expenses without realizing the expected benefits of

33

the applicable merger. Any of the foregoing, or other risks arising in connection with the failure of or delay in consummating either merger, including the diversion of management attention from pursuing other opportunities and the constraints in the applicable merger agreement on the ability to make significant changes to each party’s ongoing business during the pendency of the applicable merger, could have a material adverse effect on each party’s business, financial condition and results of operations.

Additionally, Simmons’, Landmark’s or Triumph’s business may have been adversely impacted by the failure to pursue other beneficial opportunities due to the focus of management on the applicable merger, without realizing any of the anticipated benefits of completing the applicable merger, and the market price of Simmons common stock might decline to the extent that the current market price reflects a market assumption that the mergers will be completed. If either merger agreement is terminated and a party’s board of directors seeks another merger or business combination, such party’s shareholders cannot be certain that such party will be able to find a party willing to engage in a transaction on more attractive terms than the applicable merger.

Some of the conditions to each merger may be waived by Simmons or Landmark, in the case of the Landmark merger, or Simmons or Triumph, in the case of the Triumph merger, without resoliciting shareholder approval of the applicable merger agreement.

Some of the conditions to the Landmark merger and the Triumph merger set forth in the applicable merger agreement may be waived by Simmons or Landmark, with respect to the Landmark merger agreement, or Simmons or Triumph, with respect to the Triumph merger agreement, subject to the agreement of the other party in specific cases. See the section entitled “The Merger Agreements—Conditions to Consummation of the Mergers.” If any such conditions are waived, Simmons and Landmark or Triumph, as applicable, will evaluate whether an amendment of this proxy statement/prospectus and solicitation of proxies is warranted. In the event that the Landmark board of directors or Triumph board of directors, as applicable, determines that solicitation of Landmark shareholders or Triumph shareholders, respectively, is not warranted, Simmons and Landmark, in the case of the Landmark merger, and Simmons and Triumph, in the case of the Triumph merger, will have the discretion to complete the applicable merger without seeking further shareholder approval.

Simmons, Landmark and Triumph will be subject to business uncertainties and contractual restrictions while the mergers are pending.

Uncertainty about the effect of the mergers on employees, customers (including depositors and borrowers), suppliers and vendors may have an adverse effect on the business, financial condition and results of operations of the parties to each merger. These uncertainties may impair Simmons’, Landmark’s or Triumph’s ability to attract, retain and motivate key personnel and customers (including depositors and borrowers) pending the consummation of the mergers, as such personnel and customers may experience uncertainty about their future roles and relationships following the consummation of the mergers. Additionally, these uncertainties could cause customers (including depositors and borrowers), suppliers, vendors and others who deal with Simmons, Landmark and/or Triumph to seek to change existing business relationships with Simmons, Landmark and/or Triumph or fail to extend an existing relationship with Simmons, Landmark and/or Triumph. In addition, competitors may target each party’s existing customers by highlighting potential uncertainties and integration difficulties that may result from the mergers.

The pursuit of the mergers and the preparation for the integration may place a burden on each party’s management and internal resources. Any significant diversion of management attention away from ongoing business concerns and any difficulties encountered in the transition and integration process could have a material adverse effect on each party’s business, financial condition and results of operations.

In addition, each merger agreement restricts each party thereto from taking certain actions without the other party’s consent while the applicable merger is pending. These restrictions could have a material adverse effect

34

on each party’s business, financial condition and results of operations. See the section entitled “The Merger Agreements—Covenants and Agreements” for a description of the restrictive covenants applicable to Simmons and Landmark, in the case of the Landmark merger agreement, and to Simmons and Triumph, in the case of the Triumph merger agreement.

Landmark’s and Triumph’s respective directors and executive officers have interests in the applicable merger that may be different from the interests of Landmark shareholders and Triumph shareholders, respectively.

Landmark’s and Triumph’s respective directors and executive officers have interests in the applicable merger that may be different from, or in addition to, the interests of Landmark shareholders and Triumph shareholders, respectively. The Landmark board of directors and Triumph board of directors were aware of these applicable interests and considered them, among other matters, in approving the Landmark merger agreement and Triumph merger agreement, respectively, and the transactions contemplated by the applicable merger agreement and recommending to the Landmark shareholders and Triumph shareholders, respectively, that they vote to approve the applicable merger proposal. These interests are described in more detail in the sections entitled “The Landmark Merger—Interests of Landmark’s Directors and Executive Officers in the Landmark Merger” and “The Triumph Merger—Interests of Triumph’s Directors and Executive Officers in the Triumph Merger.”

The merger agreements contain provisions that may discourage other companies from pursuing, announcing or submitting a business combination proposal to Landmark, in the case of the Landmark merger agreement, and Triumph, in the case of the Triumph merger agreement, that might result in greater value to Landmark shareholders or Triumph shareholders, respectively.

The merger agreements contain provisions that may discourage a third party from pursuing, announcing or submitting a business combination proposal to Landmark, in the case of the Landmark merger agreement, and Triumph, in the case of the Triumph merger agreement, that might result in greater value to Landmark shareholders or Triumph shareholders, respectively, than the applicable merger. These provisions include a general prohibition on Landmark and Triumph, respectively, from soliciting or entering into discussions with any third party regarding any acquisition proposal or offers for competing transactions, as described in the section entitled “The Merger Agreements—Agreement Not to Solicit Other Offers.” Furthermore, if the Landmark merger agreement or the Triumph merger agreement is terminated, under certain circumstances, Landmark may be required to pay Simmons a termination fee equal to $7,000,000 upon termination of the Landmark merger agreement, and Triumph may be required to pay Simmons a termination fee equal to $6,500,000 upon termination of the Triumph merger agreement, as described in the section entitled “The Merger Agreements—Termination Fees.” Each of Landmark and Triumph also has an unqualified obligation to submit its respective merger-related proposals to a vote by its respective shareholders, including if Landmark or Triumph, as applicable, receives an unsolicited proposal that the Landmark board of directors or Triumph board of directors, respectively, has determined in good faith is superior to the applicable merger. See the section entitled “The Merger Agreements—Special Meetings and Recommendations of the Board of Directors of Landmark and Triumph.”

In connection with the Landmark merger agreement, each of the directors and certain executive officers of Landmark, in their capacities as individuals, have separately entered into Landmark voting agreements pursuant to which they agreed to vote their beneficially owned shares of Landmark common stock in favor of the Landmark merger proposal and certain related matters and against alternative transactions. In connection with the Triumph merger agreement, each of the directors and certain executive officers of Triumph, in their capacities as individuals, have separately entered into Triumph voting agreements pursuant to which they agreed to vote their beneficially owned shares of Triumph common stock in favor of the Triumph merger proposal and certain related matters and against alternative transactions. As of the Landmark record date, shares constituting approximately 21.54% of the Landmark common stock entitled to vote at the Landmark special meeting are subject to Landmark

35

voting agreements; and as of the Triumph record date, shares constituting approximately 44.49 % of the Triumph common stock entitled to vote at the Triumph special meeting are subject to Triumph voting agreements. For further information, see the section entitled “The Merger Agreements—Voting Agreements.”

Each of the Landmark merger and the Triumph merger is expected to, but may not, qualify as a reorganization under Section 368(a) of the Code.

The parties expect that and intend for each of the Landmark merger and the Triumph merger to be treated as a “reorganization” within the meaning of Section 368(a) of the Code. The respective obligations of Simmons and Landmark to complete the Landmark merger are contingent upon Simmons and Landmark receiving a legal opinion from Covington that the Landmark merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code. Similarly, the respective obligations of Simmons and Triumph to complete the Triumph merger are conditioned upon Simmons and Triumph receiving a legal opinion from Covington to the effect that the Triumph merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code. These tax opinions represent the legal judgment of counsel rendering the opinions and are not binding on the United States Internal Revenue Service, or the IRS, or the courts. The expectations that each of the mergers will be treated as a “reorganization” within the meaning of Section 368(a) of the Code reflect assumptions and takes into account the relevant information available to Simmons and Landmark or Triumph, as applicable, at the time. However, this information is not a fact and should not be relied upon as necessarily indicative of future results. Furthermore, such expectation constitutes a forward-looking statement. For information on forward-looking statements, see the section entitled “Cautionary Statement Regarding Forward-Looking Statements.”

If either the Landmark merger or the Triumph merger does not qualify as a “reorganization” within the meaning of Section 368(a) of the Code, then a holder of Landmark common stock or Triumph common stock, depending on whether the failed merger is the Landmark merger or the Triumph merger, may be required to recognize gain or loss equal to the difference between (1) the sum of the fair market value of Simmons common stock received by the Landmark shareholder or Triumph shareholder, as applicable, in the merger and the amount of cash, if any, received by the Landmark shareholder or Triumph shareholder in the merger, and (2) the Landmark shareholder or Triumph shareholder’s adjusted tax basis in the shares of Landmark common stock or Triumph common stock, respectively, exchanged therefor. For further information, please refer to the section entitled “Material United States Federal Income Tax Consequences of the Mergers.” You should consult your tax advisor to determine the particular tax consequences to you.

The opinions of the respective financial advisors to the Landmark board of directors and the Triumph board of directors prior to the signing of the applicable merger agreement will not reflect changes in circumstances after the respective dates of the opinions.

The Landmark board of directors received a written opinion from Olsen Palmer, dated June 4, 2021, which is attached as Annex E to this proxy statement/prospectus. The Triumph board of directors received a written opinion from Southard Financial, dated June 4, 2021, which is attached hereto as Annex F to this proxy statement/prospectus. For a description of these opinions, see the sections entitled “The Landmark Merger—Opinion of Landmark’s Financial Advisor” and “The Triumph Merger—Opinion of Triumph’s Financial Advisor.” Such opinions have not been updated as of the date of this proxy statement/prospectus and will not be updated at, or prior to, the time of the completion of the mergers. Changes in the operations and prospects of Simmons, Landmark or Triumph, general market and economic conditions and other factors that may be beyond the control of Simmons, Landmark and Triumph may alter the value of Simmons, Landmark or Triumph or the prices of shares of Simmons common stock, Landmark common stock or Triumph common stock by the time the mergers are completed. The opinions do not speak as of the time the mergers are completed or as of any other date than the date of the opinions. Further, the Olsen Palmer and Southard Financial opinions regarding the Landmark merger and Triumph merger, respectively, do not take the Triumph merger or Landmark merger, respectively, into consideration. For a description of the other factors considered by the Landmark board

36

of directors in determining to approve the Landmark merger and the Triumph board of directors in determining to approve the Triumph merger, see the sections entitled “The Landmark Merger—Landmark’s Reasons for the Landmark Merger and Recommendation of the Landmark Board of Directors” and “The Triumph Merger—Triumph’s Reasons for the Triumph Merger and Recommendation of the Triumph Board of Directors.”

Litigation against Landmark, Triumph or Simmons, or the members of the Landmark, Triumph or Simmons board of directors, could prevent or delay the completion of the mergers.

While Simmons, Landmark and Triumph believe that any claims that may be asserted by purported shareholder plaintiffs related to the mergers would be without merit, the results of any such potential legal proceedings are difficult to predict and could delay or prevent the mergers from being competed in a timely manner. The existence of litigation related to the Landmark merger or the Triumph merger could affect the likelihood of obtaining the required approval from Landmark shareholders or Triumph shareholders, respectively. Moreover, any litigation could be time consuming and expensive, could divert Simmons, Landmark and Triumph management’s attention away from their regular business, and any lawsuit adversely resolved against Landmark, Triumph, Simmons or members of the Landmark, Triumph or Simmons board of directors, could have a material adverse effect on each party’s business, financial condition and results of operations.

One of the conditions to the consummation of each merger is the absence of any law or order (whether temporary, preliminary or permanent) by any court or regulatory authority of competent jurisdiction prohibiting, restricting or making illegal consummation of the transactions contemplated by the applicable merger agreement (including the applicable merger). Consequently, if a settlement or other resolution is not reached in any lawsuit that is filed or any regulatory proceeding and a claimant secures injunctive or other relief or a regulatory authority issues an order or other directive prohibiting, restricting or making illegal consummation of the transactions contemplated by either of the merger agreements (including the applicable merger), then such injunctive or other relief may prevent such merger from becoming effective in a timely manner or at all.

The COVID-19 pandemic may delay and adversely affect the completion of the mergers.

The COVID-19 pandemic has created economic and financial disruptions that have adversely affected, and are likely to continue to adversely affect, the business, financial condition, liquidity, capital and results of operations of Simmons, Landmark and Triumph. If the effects of the COVID-19 pandemic cause continued or extended decline in the economic environment and the financial results of Simmons, Landmark or Triumph, or the business operations of Simmons, Landmark or Triumph are disrupted as a result of the COVID-19 pandemic, efforts to complete the mergers and integrate the businesses of Landmark and Triumph with Simmons may also be delayed and adversely affected. Additional time may be required to obtain the requisite regulatory approvals, and regulatory authorities may impose additional requirements on Simmons, Landmark or Triumph that must be satisfied prior to completion of the mergers, which could delay and adversely affect the completion of the mergers.

Risks Relating to the Combined Company’s Business Following the Mergers

The shares of Simmons common stock to be received by holders of Landmark common stock and holders of Triumph common stock as a result of the Landmark merger and Triumph merger, respectively, will have different rights from the shares of Landmark common stock and Triumph common stock, respectively.

The rights of Landmark shareholders are currently governed by the Landmark charter and the Landmark bylaws. The rights of Triumph are currently governed by the Triumph charter and the Triumph bylaws. Upon completion of the mergers, the rights of former holders of Landmark common stock and Triumph common stock will be governed by the Simmons charter and the Simmons bylaws. Simmons is organized under Arkansas law, while Landmark and Triumph are organized under Tennessee law. The rights associated with Landmark common

37

stock and Triumph common stock are different from the rights associated with Simmons common stock. See the sections entitled “Comparison of Shareholders’ Rights of Simmons and Landmark” and “Comparison of Shareholders’ Rights of Simmons and Triumph” for a discussion of the different rights associated with Simmons common stock.

Sales of substantial amounts of Simmons common stock in the open market by former holders of Landmark common stock and/or Triumph common stock could depress Simmons’ stock price.

Shares of Simmons common stock that are issued to holders of Landmark common stock in the Landmark merger and holders of Triumph common stock in the Triumph merger will be freely tradable without restrictions or further registration under the Securities Act. Simmons currently expects to issue 4,500,000 shares of Simmons common stock in connection with the Landmark merger and 4,164,839 shares of Simmons common stock in connection with the Triumph merger. If the mergers are completed and if Landmark’s and/or Triumph’s former shareholders sell substantial amounts of Simmons common stock in the public market following completion of the mergers, the market price of Simmons common stock may decrease. These sales might also make it more difficult for Simmons to sell equity or equity-related securities at a time and price that it otherwise would deem appropriate.

Combining Landmark and Triumph with Simmons may be more difficult, costly or time consuming than expected and the anticipated benefits and cost savings of the mergers may not be realized.

The success of the mergers will depend on, among other things, the combined company’s ability to combine the businesses of Landmark and Triumph with Simmons. If the combined company is not able to successfully achieve this objective, the anticipated benefits of the mergers may not be realized fully, or at all, or may take longer to realize than expected.

Simmons, Landmark and Triumph have operated and, until the completion of the mergers, will continue to operate, independently. The success of the mergers, including anticipated benefits and cost savings, will depend, in part, on the successful combination of the businesses of Landmark and Triumph with Simmons. To realize these anticipated benefits and cost savings, after the completion of the mergers, Simmons expects to integrate Landmark’s and Triumph’s businesses into its own. It is possible that the integration process could result in the loss of key employees, the disruption of each company’s ongoing businesses or inconsistencies in standards, controls, procedures and policies that adversely affect the combined company’s ability to maintain relationships with clients, customers, depositors and employees or to achieve the anticipated benefits and cost savings of the mergers. The loss of key employees could have an adverse effect on the companies’ financial results and the value of their common stock. If Simmons experiences difficulties with the integration process, the anticipated benefits of the mergers may not be realized fully, or at all, or may take longer to realize than expected. As with any merger of financial institutions, there also may be business disruptions that cause Simmons, Landmark and/or Triumph to lose current customers or cause current customers to remove their accounts from Simmons, Landmark and/or Triumph and move their business to competing financial institutions. Integration efforts will also divert management attention and resources. These integration matters could have an adverse effect on each of Simmons, Landmark or Triumph during this transition period and for an undetermined period after consummation of the mergers.

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

The combined company expects to incur substantial expenses in connection with consummation of the mergers and combining the business, operations, networks, systems, technologies, policies and procedures of Landmark and Triumph with Simmons. Although Simmons, Landmark and Triumph have assumed that a certain level of transaction and combination expenses would be incurred, there are a number of factors beyond their control that could affect the total amount or the timing of their combination expenses. Many of the expenses that

38

will be incurred, by their nature, are difficult to estimate accurately at the present time. Due to these factors, the transaction and combination expenses associated with the mergers could, particularly in the near term, exceed the savings that the combined company expects to achieve from the elimination of duplicative expenses and the realization of economies of scale and cost savings related to the combination of the businesses following the consummation of the mergers. As a result of these expenses, each of Simmons, Landmark and Triumph expects to take charges against their earnings before and after the completion of the mergers. The charges taken in connection with the mergers are expected to be significant, although the aggregate amount and timing of such charges are uncertain at present.

Holders of Simmons, Landmark and Triumph common stock will have a reduced ownership and voting interest after the mergers and will exercise less influence over management.

Holders of Simmons common stock, Landmark common stock and Triumph common stock currently have the right to vote for the election of the directors and on other matters affecting Simmons, Landmark and Triumph, respectively. Upon the completion of the mergers, each holder of Landmark common stock and each holder of Triumph common stock who receives shares of Simmons common stock will become a shareholder of Simmons with a percentage ownership of Simmons common stock that is smaller than such shareholder’s percentage ownership of Landmark common stock or Triumph common stock, respectively. Following completion of both of the mergers, it is currently expected that former holders of Landmark common stock as a group will own approximately 3.84 % of the combined company’s common stock, former holders of Triumph common stock as a group will own approximately 3.56 % of the combined company’s common stock, and existing holders of Simmons common stock as a group will own approximately 92.60 % of the combined company’s common stock. As a result, Landmark shareholders and Triumph shareholders will have less influence on the management and policies of the combined company than they now have on the management and policies of Landmark and Triumph, respectively, and existing Simmons shareholders may have less influence than they now have on the management and policies of Simmons.

Risks Relating to an Investment in Simmons Common Stock

The market price of Simmons common stock may decline as a result of the mergers.

The market price of Simmons common stock may decline as a result of the mergers if Simmons does not achieve the perceived benefits of the mergers or the effect of the mergers on Simmons’ financial results is not consistent with the expectations of financial or industry analysts. In addition, upon completion of the mergers, Simmons, Landmark and Triumph shareholders will own interests in a combined company operating an expanded business with a different mix of assets, risks and liabilities. Existing Simmons, Landmark and Triumph 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.

The market price of the common stock of the combined company after the mergers may be affected by factors different from those currently affecting the shares of Simmons, Landmark or Triumph common stock.

Upon the completion of the mergers, Simmons shareholders, Landmark shareholders and Triumph shareholders will become shareholders of the combined company. Simmons’ business differs from that of each of Landmark and Triumph, and, accordingly, the results of operations of the combined company and the market price of the combined company’s shares of common stock may be affected by factors different from those currently affecting the independent results of operations of each of Simmons, Landmark and Triumph. For a further discussion of the businesses of Simmons, Landmark and Triumph, see the section entitled “Information about the Companies.” For a discussion of the businesses of Simmons and of certain factors to consider in connection with such business, please see the documents incorporated by reference into this proxy statement/prospectus and referred to in the section entitled “Where You Can Find More Information.”

39

Simmons’ management will have broad discretion as to the use of assets acquired from the mergers, and Simmons may not use these assets effectively.

Simmons’ management will have broad discretion in the application of the assets from the mergers and could utilize the assets in ways that do not improve Simmons’ results of operations or enhance the value of its common stock. Holders of Landmark common stock and holders of Triumph common stock will not have the opportunity, as part of their investment decision, to assess whether these acquired assets are being used appropriately. Simmons’ failure to utilize these assets effectively could have a material adverse effect on the combined company’s business, financial condition and results of operations and cause the price of Simmons common stock to decline.

Simmons’ rights and the rights of Simmons shareholders to take action against Simmons’ directors and officers are limited.

The Simmons charter eliminates Simmons’ directors’ liability to Simmons and its shareholders for money damages for breach of fiduciary duties as a director to the fullest extent permitted by Arkansas law. Arkansas law provides that an officer has no liability in that capacity if he or she performs his or her duties in good faith, in a manner he or she reasonably believes to be in Simmons’ best interests and with the care that an ordinarily prudent person in a like position would use under similar circumstances.

The Simmons charter, Simmons bylaws and indemnification agreements with Simmons’ directors and executive officers also require Simmons to indemnify Simmons’ directors and officers for liability resulting from actions taken by them in those capacities to the maximum extent permitted by Arkansas law. As a result, Simmons shareholders and Simmons may have more limited rights against Simmons’ directors and officers than might otherwise exist under common law. In addition, Simmons may be obligated to fund the defense costs incurred by Simmons’ directors and officers.

As of the Landmark record date, there were 22,215,981 shares of Landmark common stock outstanding and entitled to notice of, and to vote at, the Landmark special meeting, held by approximately 256 Landmark shareholders of record. Each Landmark shareholder will be entitled to one vote for each share of Landmark common stock held of record.

Landmark shareholders that are present at the Landmark special meeting in person or by proxy and holding a majority of the shares of Landmark common stock issued, outstanding and entitled to be voted at Landmark special meeting, will constitute a quorum at the Landmark special meeting. All shares of Landmark common

41

stock present at the Landmark special meeting in person or by proxy, including abstentions, if any, will be treated as present for purposes of determining the presence or absence of a quorum for all matters voted on at the Landmark special meeting.

Under the Landmark bylaws, if a quorum is not present at the Landmark special meeting, a majority in voting interest of those present in person or by proxy and entitled to vote at the Landmark special meeting may adjourn the meeting from time to time without notice to the Landmark shareholders until Landmark shareholders holding the amount of stock required for a quorum are present or represented. In the absence of all of the Landmark shareholders, any officer entitled to preside at, or to act as presiding officer of, the Landmark special meeting may adjourn the meeting from time to time without notice to the Landmark shareholders until Landmark shareholders holding the amount of stock required for a quorum are present or represented.

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

Landmark merger proposal:

| · | Vote required: Approval of the Landmark merger proposal requires the affirmative vote of holders of at least a majority of the outstanding shares of Landmark common stock entitled to vote on the proposal.

| · | Effect of abstentions and broker non-votes: If you mark “ABSTAIN” on your proxy, fail to submit a proxy or vote in person at the Landmark special meeting, or if you fail to instruct your bank, broker or other nominee how to vote with respect to the Landmark merger proposal, it will have the same effect as a vote against the proposal.

Landmark adjournment proposal:

| · | Vote required: Approval of the Landmark adjournment proposal requires the affirmative vote of holders of at least a majority of the outstanding shares of Landmark common stock present or represented by proxy at the Landmark special meeting and entitled to vote on the proposal. A quorum is not required for a vote on the Landmark adjournment proposal.

| · | Effect of abstentions and broker non-votes: If you mark “ABSTAIN” on your proxy, it will have the same effect as a vote against the Landmark adjournment proposal. If you fail to submit a proxy or vote in person at the Landmark special meeting, or if you fail to instruct your bank, broker or other nominee how to vote with respect to the Landmark adjournment proposal, it will have no effect on the proposal.

Shares Held by Directors and Executive Officers

As of the Landmark record date, there were 22,215,981 shares of Landmark common stock outstanding and entitled to vote at the Landmark special meeting. As of the Landmark record date, the directors and executive officers of Landmark and their affiliates beneficially owned and were entitled to vote approximately 4,862,973 shares of Landmark common stock, representing approximately 21.89% of the shares of Landmark common stock outstanding on that date. Landmark currently expects that the shares of Landmark common stock beneficially owned by its directors and executive officers will be voted in favor of the Landmark merger proposal and the Landmark adjournment proposal. In connection with the Landmark merger agreement, each of the directors and certain executive officers of Landmark, in their capacities as individuals, have separately entered into Landmark voting agreements pursuant to which they agreed to vote their beneficially owned shares of Landmark common stock in favor of the Landmark merger proposal and certain related matters and against alternative transactions. For further information, see the section entitled “The Merger Agreements—Voting Agreements.”

42

Voting of Proxies; Incomplete Proxies

A Landmark shareholder may vote by proxy or in person at the Landmark special meeting. If you hold your shares of Landmark common stock in your name as a shareholder of record, you may use one of the following methods to submit a proxy as a Landmark shareholder:

| · | by mail by completing, signing, dating and returning the proxy in the enclosed envelope, which requires no additional postage if mailed in the United States; or

| · | in person at the Landmark special meeting.

When a properly executed proxy is returned, the shares of Landmark common stock represented by it will be voted at the Landmark special meeting in accordance with the instructions contained on the proxy. If any proxy is returned without indication as to how to vote, the shares of Landmark common stock represented by the proxy will be voted in favor of both the Landmark merger proposal and the Landmark adjournment proposal.

For Landmark shareholders whose shares are registered in the name of a bank, broker or other nominee, please consult the voting instructions provided by your bank, broker or other nominee.

If your shares are held in “street name” by a bank, broker or other nominee, you should check the voting form used by that firm to determine how to vote. You may not vote shares held in “street name” by returning a proxy directly to Landmark or by voting at the Landmark special meeting unless you provide a “legal proxy,” which you must obtain from your bank, broker or other nominee.

Every Landmark shareholder’s vote is important. Accordingly, you should complete, sign, date and return the enclosed proxy, whether or not you plan to attend the Landmark special meeting. Sending in your proxy will not prevent you from voting your shares personally at the Landmark special meeting, since you may revoke your proxy at any time before it is voted.

Shares Held in “Street Name”

If your shares are held in “street name” by a bank, broker or other nominee, you must provide the record holder of your shares with instructions on how to vote your shares. Banks, brokers and other nominees who hold shares of Landmark 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 voting discretion with respect to the approval of matters determined to be “non-routine,” without specific instructions from the beneficial owner. Landmark expects that all proposals to be voted on at the Landmark special meeting will be “non-routine” matters. Broker non-votes are shares held by a bank, broker or other nominee with respect to which such entity 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. If your bank, broker or other nominee holds your shares of Landmark common stock in “street name,” such entity will vote your shares of Landmark common stock only if you provide instructions on how to vote by complying with the voter instruction form sent to you by your bank, broker or other nominee with this proxy statement/prospectus.

Revocability of Proxies and Changes to a Landmark Shareholder’s Vote

If you hold stock in your name as a shareholder of record, you may change your vote or revoke any proxy at any time before it is voted by (1) completing, signing, dating and returning a proxy with a later date, (2) delivering a written revocation letter to Landmark’s head of investor relations, or (3) voting in person at the

43

Landmark special meeting. If you choose to send a completed proxy bearing a later date than your original proxy, the new proxy must be received before the beginning of the Landmark special meeting.

Any Landmark shareholder entitled to vote at the Landmark special meeting may vote regardless of whether or not a proxy has been previously given, but simply attending the Landmark special meeting (without notifying Landmark’s head of investor relations) will not constitute revocation of a previously given proxy.

Written notices of revocation and other communications about revoking your proxy should be addressed to:

Landmark Community Bank
5880 Ridge Bend Road
Memphis, Tennessee 38120
Attention: Deborah R. Field

If your shares are held in “street name” by a bank, broker or other nominee, you should follow the instructions of your bank, broker or other nominee regarding the revocation of voting instructions.

Solicitation of Proxies

Landmark is soliciting proxies from its shareholders in conjunction with the Landmark merger. Landmark will bear the entire cost of soliciting proxies from Landmark shareholders. In addition to solicitation of proxies by mail, Landmark will request that banks, brokers, nominees and other record holders send proxies and proxy materials to the beneficial owners of Landmark common stock and secure their voting instructions. Landmark will reimburse the record holders for their reasonable expenses in taking those actions. If necessary, Landmark may use its directors, officers or employees, who will not be specially compensated, to solicit proxies from Landmark shareholders, either personally or by telephone, facsimile, letter or electronic means.

Attending the Landmark Special Meeting

If you are a Landmark shareholder as of the Landmark record date, you may vote your shares in person at the Landmark special meeting. Even if you currently plan to attend the Landmark special meeting, it is recommended that you also submit your proxy as described below, so your vote will be counted if you later decide not to attend the Landmark special meeting. If you submit your vote by proxy and later decide to vote at the Landmark special meeting, the vote you submit at the Landmark special meeting will override your proxy vote. If your shares of Landmark common stock are held in “street name” by a bank, broker or other nominee, please follow the instructions on the voting instruction form provided by the record holder. “Street name” shareholders who wish to vote in person at the Landmark special meeting will need to obtain a legal proxy from the institution that holds their shares.

Assistance

If you need assistance in completing your proxy, have questions regarding the Landmark special meeting, or would like additional copies of this proxy statement/prospectus, please contact James P. “Jake” Farrell, telephone: (901) 457-3111, email: jakefarrell@landmarkbanktn.com; or Charles E. “Buddy” Dickey, telephone: (901) 457-3123, email: cdickeylandmarkbanktn.com.

THE LANDMARK PROPOSALS

Proposal 1: Landmark Merger Proposal

Landmark is asking Landmark shareholders to approve the Landmark merger agreement, including the Landmark merger and all transactions contemplated thereby. For a detailed discussion of the terms and conditions of the Landmark merger agreement, see the section entitled “The Merger Agreements.” Landmark shareholders should read this proxy statement/prospectus, including any documents incorporated by reference into this proxy statement/prospectus, and its annexes, carefully and in their entirety for more detailed information concerning the Landmark merger agreement and the Landmark merger. A copy of the Landmark merger agreement is attached to this proxy statement/prospectus as Annex A.

As discussed in the section entitled “The Landmark Merger—Landmark’s Reasons for the Landmark Merger and Recommendation of the Landmark Board of Directors,” after careful consideration, the Landmark board of directors approved the Landmark merger agreement and declared the Landmark merger agreement and the transactions contemplated thereby, including the Landmark merger, to be advisable and in the best interest of Landmark and Landmark shareholders.

Required Vote

Approval of the Landmark merger proposal requires the affirmative vote of holders of at least a majority of the outstanding shares of Landmark common stock entitled to vote on the proposal. If you mark “ABSTAIN” on your proxy, fail to submit a proxy or vote in person at the Landmark special meeting, or if you fail to instruct your bank, broker or other nominee how to vote with respect to the Landmark merger proposal, it will have the same effect as a vote against the proposal.

The Landmark board of directors recommends that Landmark shareholders vote “FOR” the Landmark merger proposal.

Proposal 2: Landmark Adjournment Proposal

Landmark is asking Landmark shareholders to approve one or more adjournments of the Landmark special meeting, if necessary or appropriate, to solicit additional proxies in favor of approval of the Landmark merger proposal if there are insufficient votes at the time of such adjournment to approve the Landmark merger proposal.

If, at the Landmark special meeting, there is an insufficient number of shares of Landmark common stock present or represented by proxy and voting in favor of the Landmark merger proposal, Landmark will move to adjourn the Landmark special meeting in order to enable the Landmark board of directors to solicit additional proxies in favor of the Landmark merger proposal. If the Landmark shareholders approve the Landmark adjournment proposal, Landmark may adjourn the Landmark special meeting and use the additional time to solicit additional proxies, including the solicitation of proxies from Landmark shareholders who have previously voted. Notice need not be given of the adjourned meeting if the time and place of the adjourned meeting are announced at the Landmark special meeting. If the meeting is adjourned to a date more than four months after the date fixed for the original meeting, Landmark must fix a new record date. Even if a quorum is not present, the Landmark special meeting may be adjourned by the affirmative vote of a majority in voting interest of those present in person or by proxy and entitled to vote at the Landmark special meeting until Landmark shareholders holding the amount of stock required for a quorum are present or represented. In the absence of all the Landmark shareholders, any officer entitled to preside at, or to act as presiding officer of, the Landmark special meeting may adjourn the meeting from time to time without notice to the Landmark shareholders until Landmark shareholders holding the amount of stock required for a quorum are present or represented.

45

Required Vote

Approval of the Landmark adjournment proposal requires the affirmative vote of holders of at least a majority of the outstanding shares of Landmark common stock present or represented by proxy at the Landmark special meeting and entitled to vote on the proposal. A quorum is not required for a vote on the Landmark adjournment proposal. If you mark “ABSTAIN” on your proxy, it will have the same effect as a vote against the Landmark adjournment proposal. If you fail to submit a proxy or vote in person at the Landmark special meeting, or if you fail to instruct your bank, broker or other nominee how to vote with respect to the Landmark adjournment proposal, it will have no effect on the proposal.

The Landmark board of directors recommends that Landmark shareholders vote “FOR” the Landmark adjournment proposal.

Other Matters to Come Before the Landmark Special Meeting

As of the date of this proxy statement/prospectus, the Landmark board of directors is not aware of any matters that will be presented for consideration at the Landmark special meeting other than as described in this proxy statement/prospectus.

Landmark Community Bank

5880 Ridge Bend Road

Memphis, Tennessee 38120

Telephone: (901) 850-0555

Landmark is a Tennessee state-chartered bank. Landmark operates out of a main office in Memphis, Tennessee, with seven other branch offices located in in the Memphis and Nashville, Tennessee metropolitan areas. As of March 31, 2021, Landmark had total assets of $1.0 billion, total net loans of $0.8 billion, total deposits of $0.8 billion, and total shareholders’ equity of $102 million. Landmark does not have a class of securities registered under Section 12 of the Exchange Act and is not subject to the reporting requirements of Section 13(a) or 15(d) of the Exchange Act, and, accordingly, does not file documents or reports with the SEC.

Landmark conducts a full-service banking business in its service area, emphasizing the banking needs of individuals and small to medium-sized businesses. Landmark draws most of its customer deposits and conducts most of its lending transactions from and within a primary service area in Shelby County, the western area of Fayette County, Davidson County, and Williamson County, Tennessee.

The principal business of Landmark is to accept deposits from the public and to make loans and other investments. The principal sources of funds for Landmark’s loans and investments are demand, time, savings,

53

money market deposits, retirement accounts and other deposits (including negotiable order of withdrawal or NOW accounts). In addition, Landmark receives funds from amortization and prepayment of loans, sales to other lenders or institutions of loans or participations in loans, fees received from other lenders or institutions for servicing loans sold to such lenders or institutions, and borrowings. The principal sources of income for Landmark are interest and fees collected on loans, including fees received for servicing loans sold to other lenders or institutions, and, to a lesser extent, interest and dividends collected on other investments. The primary expenses of Landmark are interest paid on savings and other deposits (including NOW accounts), interest paid on other borrowings by Landmark, employee compensation, office expenses, and other overhead expenses.

The profitability of Landmark depends primarily on the extent to which Landmark’s earnings, primarily interest collected on loans, exceed Landmark’s expenses, primarily interest paid by Landmark on deposits used to fund its loans. The extent to which Landmark will be able to produce and maintain a positive spread between its income and expenses will be affected by, among other things, the actions of its competitors and changes in applicable laws and regulations, monetary control policies, general economic conditions, and the extent to which Landmark makes relatively short-term loans or makes long-term loans with variable or adjustable interest rates.

Landmark is authorized to make both secured and unsecured loans to individuals, partnerships, corporations, and other entities. Landmark’s lending business consists principally of making consumer loans to individuals and commercial loans to medium-sized business and professional concerns. Landmark may also emphasize the extension of relatively short-term loans or, to the extent it makes long-term loans, the extension of loans with variable or adjustable interest rates, in an effort to retain the flexibility to maintain a positive spread between its interest income and expense. The extent to which Landmark may be successful in implementing this lending policy, however, will depend in part upon consumer acceptance, the actions of Landmark’s competitors, and, to some extent, usury laws and other rules and regulations applicable to Landmark.

Telephone: (901) 333-8800

Triumph is a bank holding company registered under the BHC Act. Triumph was incorporated in Tennessee in 2005 to serve as the bank holding company for and sole shareholder of Triumph Bank, which was incorporated as a Tennessee state-chartered bank in 2006. Triumph Bank is headquartered in Memphis, Tennessee, and currently operates from nine office locations (including six full-service branches and three loan production offices) in Arlington, Brentwood, Collierville, Germantown, Memphis, Nashville, and Union City in Tennessee. As of March 31, 2021, Triumph had consolidated total assets of $895.5 million, total net loans of $702.9 million, total deposits of $750.0 million, and total shareholders’ equity of $89.1 million. Triumph does not have a class of securities registered under Section 12 of the Exchange Act and is not subject to the reporting requirements of Section 13(a) or 15(d) of the Exchange Act, and, accordingly, does not file documents or reports with the SEC.

Triumph conducts a full-service banking business in its service area, emphasizing the banking needs of individuals and small to medium-sized businesses. Triumph draws most of its customer deposits and conducts most of its lending transactions from and within a primary service area in Shelby County, the western area of Fayette County, Davidson County, and Williamson County, Tennessee.

54

The principal business of Triumph is to accept deposits from the public and to make loans and other investments. The principal sources of funds for Triumph’s loans and investments are demand, time, savings, money market deposits, retirement accounts and other deposits (including NOW accounts). In addition, Triumph receives funds from amortization and prepayment of loans, sales to other lenders or institutions of loans or participations in loans, fees received from other lenders or institutions for servicing loans sold to such lenders or institutions, and borrowings. The principal sources of income for Triumph are interest and fees collected on loans, and, to a lesser extent, interest and dividends collected on other investments. The primary expenses of Triumph are interest paid on savings and other deposits (including NOW accounts), interest paid on other borrowings by Triumph, employee compensation, office expenses, and other overhead expenses.

The profitability of Triumph depends primarily on the extent to which Triumph’s earnings, primarily interest collected on loans, exceed Triumph’s expenses, primarily interest paid by Triumph on deposits used to fund its loans. The extent to which Triumph will be able to produce and maintain a positive spread between its income and expenses will be affected by, among other things, the actions of its competitors and changes in applicable laws and regulations, monetary control policies, general economic conditions, and the extent to which Triumph makes relatively short-term loans or makes long-term loans with variable or adjustable interest rates.

Triumph is authorized to make both secured and unsecured loans to individuals, partnerships, corporations, and other entities. Triumph’s lending business consists principally of making consumer loans to individuals and commercial loans to medium-sized business and professional entities.

THE LANDMARK MERGER

The following discussion contains material information regarding the Landmark merger. The discussion is subject to, and qualified in its entirety by reference to, the Landmark merger agreement, which is attached to this proxy statement/prospectus as Annex A and is incorporated by reference into this proxy statement/prospectus. The following is not intended to provide factual information about the parties or any of their respective subsidiaries or affiliates. This discussion does not purport to be complete and may not contain all of the information about the Landmark merger that is important to you. We urge you to read the Landmark merger agreement carefully and in its entirety, as it is the legal document governing the Landmark merger.

Terms of the Landmark Merger

Each of the Simmons board of directors, the Simmons Bank board of directors and the Landmark board of directors approved the Landmark merger agreement. The Landmark merger agreement provides that, among other things, Landmark will merge with and into Simmons Bank, with Simmons Bank as the surviving bank in the merger.

Based on the assumptions set forth below, at the Landmark effective time, each share of Landmark common stock that is issued and outstanding immediately prior to the Landmark effective time, excluding certain specified shares, will be converted into the right to receive, subject to possible adjustment, the Landmark merger consideration. In the aggregate, Simmons expects to issue approximately 4,500,000 shares of Simmons common stock and pay approximately $7,000,000 (minus the cash payment for outstanding Landmark stock options) to Landmark shareholders upon completion of the Landmark merger, subject to certain conditions and potential adjustments under the Landmark merger agreement. The Landmark merger consideration is based on the assumption that (i) 22,215,981 shares of Landmark common stock are issued and outstanding and (ii) 218,400 shares of Landmark common stock are subject to outstanding Landmark stock options with a weighted average exercise price of $3.49, in each case, immediately prior to the Landmark effective time. In addition, we have assumed that the Landmark/Simmons average closing price is equal to $27.49, which was the closing sales price of Simmons common stock on the last practicable trading day prior to printing this proxy statement/prospectus.

Simmons will not issue any fractional shares of Simmons common stock in the Landmark merger. Instead, a Landmark shareholder who would otherwise be entitled to a fractional share of Simmons common stock upon completion of the Landmark merger will receive, in lieu thereof, an amount in cash, rounded up to the nearest whole cent (without interest), determined by multiplying (i) the fraction of a share (rounded to the nearest thousandth when expressed in decimal form) of Simmons common stock that such Landmark shareholder would otherwise be entitled to receive by (ii) the Landmark/Simmons average closing price.

Landmark shareholders are being asked to approve the Landmark merger agreement, including the Landmark merger and all transactions contemplated thereby. See the section entitled “The Merger Agreements” for additional and more detailed information regarding the legal documents that govern the Landmark merger, including information about the conditions to consummation of the Landmark merger and the provisions for terminating or amending the Landmark merger agreement.

Background of the Landmark Merger

Landmark’s management and the Landmark board of directors periodically evaluate and consider various strategic alternatives, with the ultimate goal of optimizing shareholder value. Various options, such as enhancing organic growth, raising additional capital, acquiring loans or assuming deposits from other institutions, merging with a similar-sized organization, and selling Landmark are among the alternatives the Landmark board of directors has considered and evaluated on an on-going basis.

56

As a part of its on-going evaluations, and in light of national and regional market conditions in which Landmark operates, in the summer of 2017 the Landmark board of directors authorized Landmark’s chief executive officer to contact potential third parties to initiate preliminary discussions regarding whether there was any interest in pursuing a transaction. As a result of these preliminary inquiries, Landmark held more substantive discussions with four financial institutions over the course of 2018, including Simmons. None of the institutions other than Simmons expressed a desire for further discussions and none of these institutions other than Simmons entered into any non-disclosure agreements with Landmark.

In November 2018, Landmark and Simmons signed a customary non-disclosure agreement. The following month, Landmark’s Chief Executive Officer and Chief Financial Officer and Simmons’ Chief Executive Officer, Chief Financial Officer, Chief Banking Officer and Chief Administrative Officer held an in-person meeting in Memphis, Tennessee at an off-site location to discuss the potential for a transaction between the two parties.

In March 2019, Simmons made an oral offer to acquire Landmark for shares of Simmons common stock with the following terms: 100% stock offer, fixed price of $105 million, and shares would not exceed 4,000,000 or be less than 3,500,000. In April 2019, the Landmark board of directors met to consider the oral offer. At this meeting, a representative of Landmark’s financial advisor, Olsen Palmer, discussed with the Landmark board of directors the relative financial considerations with respect to such offer.

In April 2019, at the direction of the Landmark board of directors, a representative of Olsen Palmer, on behalf of Landmark, made a verbal counterproposal to Simmons with the following terms: 4.3 million shares of Simmons of common stock and $5.9 million in cash. Simmons verbally indicated its agreement to such counterproposal, but did not provide a written offer or letter of intent.

In May 2019, the Landmark board of directors met to further discuss the oral offer from Simmons. Following the meeting, Landmark offered three alternative counterproposals to Simmons: one proposal would be based on the same structure as Simmons’ prior verbal offer but with 0.2 million additional shares of Simmons common stock; one proposal would match Simmons’ prior verbal offer but include a special dividend of $0.25 per share of Landmark common stock payable to Landmark shareholders by Landmark between signing and closing; and one proposal would match Simmons’ prior verbal offer but include a floor mechanism such that the per share consideration to Landmark shareholders would not be less than $5.00. On the same date, Simmons communicated to Landmark that it was no longer interested in pursuing a transaction at that time, because it had other larger transactions it was pursuing.

In September 2019, Landmark engaged Olsen Palmer to assist Landmark in evaluating various strategic alternatives. During the remainder of 2019, Landmark had discussions with other financial institutions on a confidential basis, none of which were the financial institutions Landmark had discussions with in 2018. As a result of these conversations, several financial institutions signed non-disclosure agreements with Landmark and conducted preliminary diligence. None of these other financial institutions made an offer to acquire Landmark.

In January 2020, Simmons contacted the Chief Executive Officer of Landmark to schedule an additional meeting. Representatives of Landmark and Simmons met in February 2020 in Memphis at an off-site location and on February 12, 2020, Simmons and Landmark entered into a new non-disclosure agreement, which was substantially similar to the agreement signed in November 2018.

On February 15, 2020, Simmons submitted a new letter of intent to Landmark for its consideration, offering to acquire Landmark for a combination of 4.3 million shares of Simmons common stock and $10 million cash in aggregate transaction value. On February 18, 2020, the Landmark board of directors met and approved the terms of the letter of intent. On February 19, 2020, Landmark countersigned the letter of intent.

57

On March 4, 2020, Simmons withdrew its letter of intent from February 15, 2020, citing the concerns and uncertainty regarding the COVID-19 pandemic as the reason for its withdrawal.

Throughout the remainder of 2020, Landmark, its management and the Landmark board of directors, focused their energy on addressing the many challenges brought about due to the COVID-19 pandemic.

In January 2021, Simmons reached out to Landmark to schedule a follow-up meeting. The Chief Executive Officer of Landmark and the Chief Executive Officer of Simmons met in February 2021 in Memphis, Tennessee at an off-site location, and confirmed that the non-disclosure agreement entered into on February 12, 2020 remained binding and effective.

On February 12, 2021, Simmons submitted a new letter of intent to Landmark, offering to acquire Landmark for either $130 million cash or 4,650,000 shares of Simmons common stock valued at approximately $124.3 million. Landmark made a counterproposal for 4,650,000 shares of Simmons common stock and $15 million in cash consideration. Simmons provided a revised letter of intent on February 16, 2021, offering a combination of 4.5 million shares of Simmons common stock and $7 million in cash consideration in aggregate transaction value for the acquisition of Landmark, including the cash-out of stock options as part of the overall transaction offer.

On February 19, 2021, the Landmark board of directors met to consider the revised offer from Simmons. A representative of Olsen Palmer participated in the meeting and discussed with the Landmark board of directors this offer. After discussion among the Landmark board of directors, the board approved the terms set forth in Simmons’ letter of intent of February 12, 2021 and authorized Landmark management to countersign the letter of intent. Simmons submitted an expanded due diligence request list to Landmark on the same date.

In April 2021, Simmons submitted an initial draft of the Landmark merger agreement to Baker, Donelson, Bearman, Caldwell & Berkowitz, PC, Landmark’s counsel, which we refer to as Baker Donelson. During April and May 2021, the parties negotiated the terms of the Landmark merger agreement and the related transaction documents, including the Landmark voting agreements, and discussed such documentation with their legal and financial advisors. During this period, Landmark and Simmons exchanged several additional drafts of the Landmark merger agreement and the related transaction documents, including the Landmark voting agreements. In addition, during this time, Landmark’s management conducted diligence on Simmons, while Simmons continued its diligence on Landmark.

On May 25, 2021, the Landmark board of directors met to discuss the terms of the Landmark merger agreement and related transaction documents. A representative of Olsen Palmer attended this meeting and discussed the financial terms of the Landmark merger and provided its opinion orally 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 Olsen Palmer as set forth in its opinion, the Landmark merger consideration to be received by Landmark shareholders, as described in the section entitled “—Opinion of Landmark’s Financial Advisor,” in the proposed Landmark merger was fair, from a financial point of view, to the holders of Landmark common stock. For a description of the Olsen Palmer opinion, please refer to the section entitled “—Opinion of Landmark’s Financial Advisor.” Baker Donelson also attended this meeting and discussed the key terms of the Landmark merger agreement with the Landmark board of directors.

After listening to the presentations by its advisors and discussing the terms of the proposed Landmark merger agreement, the terms of the Landmark voting agreements, and the matters discussed during that meeting and prior meetings of the Landmark board of directors, including the factors described in the section entitled “—Landmark’s Reasons for the Landmark Merger and Recommendations of the Landmark Board of Directors,” upon a motion duly made and seconded, the Landmark board of directors determined that the Landmark merger agreement, including the Landmark merger and the other transactions contemplated thereby, was in the

58

best interests of Landmark and its shareholders, and approved the Landmark merger agreement, including the Landmark merger and the other transactions contemplated by the Landmark merger agreement and recommended that the shareholders of Landmark approve the Landmark merger.

On June 4, 2021, the Simmons board of directors held a meeting to consider the terms of the proposed Landmark merger and Landmark merger agreement. At the meeting, members of Simmons’ management reported on the status of due diligence and negotiations with Landmark. Also at the meeting, Simmons’ financial advisor reviewed with the Simmons board of directors financial aspects of the proposed Landmark merger. At the meeting, Simmons’ internal legal counsel reviewed with the Simmons board of directors its fiduciary duties and reviewed the key terms of the Landmark merger agreement and related agreements (including the Landmark voting agreements), as described elsewhere in this proxy statement/prospectus, including a summary of the provisions relating to governance of the combined company and the provisions relating to employee matters.

After considering the proposed terms of the Landmark merger agreement, the terms of the Landmark voting agreements, and taking into consideration the matters discussed during that meeting and prior meetings of the Simmons board of directors, including the factors described in the section entitled “—Simmons’ Reasons for the Landmark Merger,” the Simmons board of directors determined that the Landmark merger was consistent with Simmons’ business strategies and in the best interests of Simmons and Simmons shareholders and the Simmons board of directors voted to approve and adopt the Landmark merger agreement, the Landmark merger and the other transactions contemplated by the Landmark merger agreement.

Following the board meetings of Landmark and Simmons, on June 4, 2021, Landmark and Simmons signed the Landmark merger agreement; each of the directors and certain executive officers of Landmark signed the Landmark voting agreements; and Olsen Palmer provided the Landmark board of directors its written opinion. On June 7, 2021, the parties issued a joint press release announcing the execution of the Landmark merger agreement.

Landmark’s Reasons for the Landmark Merger and Recommendation of the Landmark Board of Directors

At the special board meeting held on May 25, 2021, the Landmark board of directors approved the Landmark merger agreement, the Landmark merger and the transactions contemplated by the Landmark merger agreement, determining that the Landmark merger is advisable and fair to, and in the best interest of, Landmark and its shareholders.

In reaching its decision to approve the Landmark merger agreement, the Landmark merger and the other transactions contemplated by the Landmark merger agreement and to recommend that Landmark shareholders vote “FOR” the Landmark merger proposal, the Landmark board of directors evaluated the Landmark merger in consultation with Landmark’s management, as well as Landmark’s financial, legal, and other professional advisors. The Landmark board of directors considered a number of factors including, without limitation, the following:

| · | information with respect to the businesses, earnings, operations, financial conditions, prospects, capital levels, and asset qualities of Landmark and Simmons, both individually and after giving effect to the Landmark merger;

| · | the market value of Simmons common stock prior to the execution of the Landmark merger agreement, the prospects for future appreciation of Simmons common stock, and the history of dividends payable by Simmons to holders of Simmons common stock;

| · | the market for and trading liquidity of Simmons common stock;

59

| · | the value to be received by Landmark shareholders in the Landmark merger as compared to potential Landmark shareholder value for Landmark as a stand-alone entity;

| · | the opinion dated June 4, 2021, of Olsen Palmer to the Landmark board of directors as to the fairness, from a financial point of view and as of the date of the opinion, to the holders of Landmark common stock of the Landmark merger consideration to be received by such holders in the proposed Landmark merger, as more fully described below in the section entitled “—Opinion of Landmark’s Financial Advisor”;

| · | the perceived risks and uncertainties attendant to Landmark’s operation as an independent banking organization, including the risks and uncertainties related to competition in market areas of Landmark Bank, increased operating and regulatory costs, interest rate environments, and potentially increased capital requirements;

| · | the expected impact of the Landmark merger on constituencies served by Landmark, including its borrowers, depositors, and communities;

| · | the effects of the Landmark merger on Landmark’s employees, including the ability of those employees to participate in Simmons’ benefit plans;

| · | the understanding that the structure and terms of the Landmark merger would result in favorable tax consequences to the shareholders of Landmark;

| · | the review of potential strategic affiliation partners other than Simmons, the prospects of such other potential strategic affiliation partners, and the (lack of) likelihood of a more favorable transaction with such potential affiliation partners;

| · | consideration of the alternatives to the Landmark merger, including remaining independent and growing organically and then selling to or merging with another institution at a future time, attempting to raise outside capital through a public sale of Landmark securities, and engaging in a merger transaction with a similarly-sized financial institution;

| · | the current environment in the financial services industry, including national, regional, and local economic conditions, the interest rate environment, continued consolidation, uncertainties in the regulatory climate for financial institutions, the current environment for community banks, including in the western and middle Tennessee markets where Landmark operates, and current financial market conditions and the likely effects of these factors on Landmark’s and Simmons’ potential growth, development, productivity, and strategic options;

| · | that a portion of the aggregate Landmark merger consideration would be paid through a fixed number of shares of Simmons common stock, such that the nominal value of the aggregate Landmark merger consideration would increase or decrease with the fluctuation of the day-to-day market price of Simmons common stock;

| · | the possible disruption to Landmark’s business that could result from the announcement of the Landmark merger and the resulting distraction of management’s attention from the day-to-day operations of Landmark’s business;

| · | that the Landmark merger agreement restricts the conduct of Landmark’s business prior to the completion of the Landmark merger which, subject to specific exceptions, could delay or prevent Landmark from undertaking business opportunities that may arise or any other action it would otherwise take with respect to the operations of Landmark absent the pending Landmark merger;

60

| · | the risks associated with the provision in the Landmark merger agreement that Landmark is not permitted to solicit or respond to any acquisition proposals, except for the limited right to terminate the Landmark merger agreement and pay a termination fee in the event Landmark receives an unsolicited superior offer, which fee may deter others from proposing an alternative transaction that may be more advantageous to the Landmark shareholders;

| · | the risk that, while Landmark expects that the Landmark merger will be consummated, there can be no assurance that all conditions to the parties’ obligations to complete the Landmark merger will be satisfied, including the risk that Landmark shareholder approval might not be obtained and, as a result, the Landmark merger may not be consummated; and

| · | the anticipated benefits to Landmark of being acquired by a larger financial institution that would be better equipped to respond to economic and industry developments and to develop and build on their positions in existing markets.

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

The Landmark board of directors collectively made its determination with respect to the Landmark merger based on the conclusion reached by its members, based on the factors that each of them considered appropriate, that the Landmark merger agreement, the Landmark merger and the other transactions contemplated by the Landmark merger agreement are in the best interests of Landmark and its shareholders and that the benefits expected to be achieved from the Landmark merger outweigh the potential risks and vulnerabilities.

This explanation of the Landmark board of directors’ reasoning and all other information presented in this section is forward-looking in nature and, therefore, should be read in light of the factors discussed in the section entitled “Cautionary Statement Regarding Forward-Looking Statements.”

For the reasons set forth above, the Landmark board of directors approved the Landmark merger agreement, the Landmark merger and the other transactions contemplated by the Landmark merger agreement, determining that they are advisable and fair to, and in the best interest of, Landmark and its shareholders and recommends that Landmark shareholders vote “FOR” the Landmark merger proposal.

Each of the directors and certain executive officers of Landmark, in their capacities as individuals, entered into Landmark voting agreements with Simmons and Landmark pursuant to which they agreed to vote “FOR” the Landmark merger proposal and “FOR” any other matters required to be approved by the Landmark shareholders in furtherance of the Landmark merger proposal. For more information regarding the Landmark voting agreements, please see the section entitled “The Merger Agreements—Voting Agreements.”

Opinion of Landmark’s Financial Advisor

Landmark retained Olsen Palmer to render financial advisory and investment banking services and to act as the exclusive financial advisor to Landmark in connection with a potential strategic combination. Olsen Palmer is an investment banking firm specializing in community bank mergers and acquisitions. Landmark selected Olsen Palmer as

61

its financial advisor on the basis of its experience and expertise in representing community banks in similar transactions and its familiarity with Landmark. Olsen Palmer, as part of its investment banking services, is regularly engaged in the valuation of financial institutions and their securities in connection with mergers and acquisitions.

In its capacity as financial advisor, Olsen Palmer provided an opinion to the Landmark board of directors in connection with the Landmark merger. At the meeting of the Landmark board on May 25, 2021, Olsen Palmer provided an oral opinion to the Landmark board of directors (which was subsequently confirmed in writing by delivery of Olsen Palmer’s written opinion dated June 4, 2021) that, based upon and subject to the various factors, assumptions and limitations set forth in such opinion, Olsen Palmer representatives’ experience as investment bankers, Olsen Palmer’s work as described in such opinion and other factors Olsen Palmer deemed relevant, as of such date, the Landmark merger consideration to be received by Landmark shareholders in the proposed Landmark merger was fair, from a financial point of view, to Landmark shareholders. The Olsen Palmer written opinion, dated June 4, 2021, is sometimes referred to as the Olsen Palmer opinion. The full text of the Olsen Palmer opinion, which sets forth, among other things, the assumptions made, procedures followed, matters considered and limitations on the review undertaken by Olsen Palmer in rendering its opinion, is attached to this proxy statement/prospectus as Annex E. The summary of the Olsen Palmer opinion set forth herein is qualified in its entirety by reference to the full text of the opinion. Landmark shareholders should read the full text of the Olsen Palmer opinion carefully and in its entirety.

The Olsen Palmer opinion is addressed to the Landmark board of directors, is directed only to the fairness, from a financial point of view, to the Landmark shareholders of the Landmark merger consideration to be received by Landmark shareholders in the Landmark merger with Simmons, and does not constitute a recommendation to any shareholder as to how such shareholder should vote or act on any matters relating to the Landmark merger. Olsen Palmer expressed no opinion as to the fairness of the Landmark merger consideration to the creditors or other constituencies of Landmark. The Olsen Palmer opinion is directed only to the fairness, from a financial point of view, of the Landmark merger consideration to the Landmark shareholders and does not address the underlying business decision of Landmark to engage in the Landmark merger or the relative merits of the Landmark merger as compared to any other alternative business strategies that might exist for Landmark. Olsen Palmer did not express any opinion as to the fairness of the amount or nature of the compensation to be received in the Landmark merger by any officer, director, or employee, or class of such persons, relative to the compensation to be received in the Landmark merger by any other shareholder. The Olsen Palmer opinion should not be construed as creating any fiduciary duty on the part of Olsen Palmer to any party or person. The Olsen Palmer opinion was not reviewed or issued by a fairness opinion committee. Olsen Palmer has not been requested to opine as to, and the Olsen Palmer opinion does not express an opinion as to or otherwise address, among other things: (i) the fairness of any portion or aspect of the Landmark merger to any one class or group of Landmark or any other party’s security holders or other constituents vis-à-vis any other class or group of Landmark’s or such other party’s security holders or other constituents (including, without limitation, the allocation of any consideration amongst or within such classes or groups of security holders or other constituents), or (ii) the fairness, financial or otherwise, of the amount, nature or any other aspect of any compensation to or consideration payable to or received by any officers, directors or employees of any party to the Landmark merger, any class of such persons or any other party, relative to the Landmark merger consideration or otherwise. Olsen Palmer expressed no opinion as to the actual value of Simmons common stock when issued in the Landmark merger or the prices at which Landmark common stock or Simmons common stock will trade following announcement of the Landmark merger or at any future time.

In performing its review, and for purposes of rendering its opinion, Olsen Palmer relied upon the accuracy and completeness of all of the financial and other information that was available to it from public sources, that was provided to Olsen Palmer by Landmark, its representatives or representatives of Simmons or that was otherwise reviewed by Olsen Palmer and has assumed, without independent verification, such accuracy and completeness of all such information. Olsen Palmer further relied on the assurances of the management of Landmark that they are not aware of any facts or circumstances that would make any of such information inaccurate or misleading. Olsen Palmer has not been asked to and has not undertaken an independent verification of any of such information and does not assume any responsibility or liability for the accuracy or completeness

62

thereof. With Landmark’s consent, Olsen Palmer relied upon the advice Landmark has received from its legal, accounting and tax advisors as to all legal, accounting and tax matters relating to the Landmark merger that is contemplated by the Landmark merger agreement and Olsen Palmer assumed that all such advice is correct.

In connection with its opinion, Olsen Palmer made such reviews, analyses and inquiries as it deemed necessary and appropriate under the circumstances. Among other things, Olsen Palmer reviewed:

| · | a draft version of the Landmark merger agreement;

| · | certain financial statements and other historical financial information of Landmark and Simmons that Olsen Palmer deemed relevant;

| · | internal financial projections for Landmark for the year ending December 31, 2021 and estimated long-term annual earnings and balance sheet growth rates for the years ending December 31, 2022, December 31, 2023, December 31, 2024, December 31, 2025, and December 31, 2026 as provided by Landmark;

| · | publicly available “street estimates” for Simmons, as well as assumed long-term dividends, and growth rates for Simmons, as discussed with representatives of Simmons;

| · | a comparison of certain financial information for Landmark with similar institutions for which publicly available information is available;

| · | the financial terms of certain recent business combinations in the commercial banking industry, to the extent publicly available;

| · | an analysis of the relative contribution that Landmark and Simmons will make to the combined company;

| · | an estimated range of the intrinsic value of Landmark based on internal financial projections for Landmark as provided by Landmark;

| · | the estimated pro forma financial impact of the Landmark merger, based on assumptions relating to transaction expenses, acquisition accounting adjustments, and cost savings as communicated to Olsen Palmer by representatives of Simmons;

| · | the current market environment generally and the banking industry in particular; and

| · | such other information, financial studies, analyses and investigations and financial, economic and market criteria as Olsen Palmer considered relevant.

Olsen Palmer also discussed with certain members of senior management of Landmark and its representatives the business, financial condition, results of operations and prospects of Landmark. Olsen Palmer held similar discussions with representatives of Simmons regarding the business, financial condition, results of operations, and prospects of Simmons.

The Olsen Palmer opinion is necessarily based on financial, economic, market and other conditions as in effect on, and the information made available to it as of June 4, 2021. Events occurring after June 4, 2021 could materially affect the Olsen Palmer opinion. Olsen Palmer has not undertaken to update, revise, reaffirm or withdraw its opinion or otherwise comment upon events occurring after June 4, 2021.

Several analytical methodologies have been employed and no one method of analysis should be regarded as critical to the overall conclusion reached by Olsen Palmer. Each analytical technique has inherent strengths

63

and weaknesses, and the nature of the available information may further affect the value of particular techniques. The overall conclusions Olsen Palmer reached are based on all the analysis and factors presented, taken as a whole, and also on application of Olsen Palmer’s own experience and judgment. Such conclusions may involve significant elements of subjective judgment and qualitative analysis. Olsen Palmer therefore gives no opinion as to the value or merit standing alone of any one or more parts of the analyses.

The following summarizes the material financial analyses that were considered by Olsen Palmer in rendering its opinion. The summary below is not a complete description of the analyses underlying the Olsen Palmer opinion or the presentation made by Olsen Palmer to the Landmark board of directors, but is a summary of all material analyses performed and presented by Olsen Palmer. No company or transaction used in the analyses described below is identical or directly comparable to Landmark, Simmons, or the contemplated merger.

Summary of Financial Terms of Landmark Merger Agreement. The financial terms of the Landmark merger agreement provide that Landmark shareholders shall be entitled to receive 4,500,000 shares of Simmons common stock and $7,000,000 in cash. Based on Simmons’s closing price on June 3, 2021 of $30.86, the implied deal value per fully diluted share equaled $6.50 and the aggregate transaction value approximated $145.9 million. Olsen Palmer calculated that the aggregate transaction value of $145.9 million represented:

| · | 143 percent of Landmark’s March 31, 2021 tangible book value;

| · | 14.0 times Landmark’s March 31, 2021 last twelve months earnings;

| · | 10.9 times Landmark’s March 31, 2021 last twelve months earnings plus cost savings;

| · | 14.5 percent of Landmark’s March 31, 2021 total assets; and

| · | 7.0 percent premium to Landmark’s March 31, 2021 core deposits.

Simmons Selected Companies Analysis. As part of its analysis, Olsen Palmer reviewed publicly available information to compare selected financial and market trading information for Simmons and a group of eight financial institutions which (i) were banks with common stock listed on the Nasdaq or the New York Stock Exchange, or NYSE; (ii) were headquartered in the United States; (iii) had total assets as of March 31, 2021 between $17.5 and $25.0 billion; (iv) had return on average assets over the twelve months ended March 31, 2021 between 0.75% and 1.25%; and (v) had nonperforming assets as a percentage of total assets as of March 31, 2021 of less than 1.0%. These eight financial institutions were as follows:

| · | Bank of Hawaii Corporation |  | · | Heartland Financial USA, Inc.
| · | Customers Bancorp, Inc. |  | · | United Community Banks, Inc.

Landmark Selected Transactions Analysis. Olsen Palmer analyzed publicly available information relating to 11 acquisitions of banks that satisfied the following selected search criteria: transactions (i) which were announced between January 1, 2020 and June 4, 2021; (ii) where targets were headquartered in the U.S.; (iii) where targets had total assets between $550 million and $1.5 billion; (iv) where targets had a return on average assets over the twelve months prior to the transaction announcement between 0.50% and 1.50%; and (v) where targets had nonperforming assets as a percentage of total assets as of March 31, 2021 less than 1.50%. The selected transactions consisted of the following (buyer / seller):

Olsen Palmer noted the following selected financial measures of the targets, in each case as of prior to the transaction announcement and for Landmark as of March 31, 2021:

|  | Total Assets ($ millions) |  |  | LTM Return on Average Assets |  |  | Nonperforming Assets to Total Assets |

Olsen Palmer reviewed the mean, median, high, low, 40th percentile, and 60th percentile values for each such metric of the acquired institution in each such transaction. The results of the selected transactions analysis are summarized below:

Relative Contribution Analysis. Olsen Palmer analyzed the relative standalone contribution of Simmons and Landmark 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, Olsen Palmer used (i) balance sheet and income statement data for Simmons and Landmark as of or for the 12-month period ended March 31, 2021 and (ii) 2019 and 2020 net income. The results of Olsen Palmer’s analysis are set forth in the following table:

|  | Simmons First National Corporation % of Total |  |  | Landmark % of Total |
Balance Sheet: |  |  |  |  |  |  |  |
Total Assets |  |  | 95.9 | % |  |  | 4.1 | %
Gross Loans Held for Investment |  |  | 93.9 | % |  |  | 6.1 | %
Deposits |  |  | 95.6 | % |  |  | 4.4 | %
Tangible Common Equity |  |  | 94.5 | % |  |  | 5.5 | %
Total Equity |  |  | 96.6 | % |  |  | 3.4 | %
Income Statement: |  |  |  |  |  |  |  |
Net Income – 2019 |  |  | 96.3 | % |  |  | 3.7 | %
Net Income – 2020 |  |  | 96.2 | % |  |  | 3.8 | %
Net Income – LTM |  |  | 95.9 | % |  |  | 4.1 | %

Landmark Discounted Cash Flow Analysis. Olsen Palmer analyzed the discounted present value of Landmark projected free cash flows for the years ending December 31, 2021 through December 31, 2026. Olsen Palmer estimated cash flows based on dividendable common equity, defined as Tier 1 Capital in excess of a minimum Tier 1 Capital ratio of 9.0%. Olsen Palmer applied a range of price to earnings multiples of 10.3x to 12.3x, based on review of price/earnings multiples for relevant indices of publicly traded bank stocks, to Landmark estimated calendar year 2026 net income to derive a terminal value.

The projected cash flows and terminal values were discounted using an estimated cost of equity capital for Landmark derived by the Duff & Phelps discount rate build-up method consisting of the sum of a risk-free rate, equity risk premium, size premium, and industry risk premium. Olsen Palmer applied a range of discount rates of 13.5% to 15.5%.

The calculations resulted in a rage of implied values of $138.3 million to $166.4 million.

The discounted cash flow analysis is a widely used valuation methodology that relies on numerous assumptions, including asset growth rates, earnings growth rates, discount rates, and terminal multiples, and the results of such methodology are highly dependent on these assumptions. The financial forecasts from 2021 – 2026 were provided by Landmark management.

Financial Impact Analysis. Olsen Palmer performed a pro forma financial impact analysis that combined projected income statement and balance sheet information of Simmons and Landmark. Using (i) publicly available consensus “street estimates” for Simmons and assumed long-term dividends, and growth rates for Simmons as provided by its representatives, (ii) pro forma assumptions regarding the impact of the Landmark merger, based on assumptions relating to transaction expenses, acquisition accounting adjustments, and cost savings as communicated to Olsen Palmer by representatives of Simmons, and (iii) financial forecasts and projections relating to the net income and tangible common equity of Landmark provided by Landmark management, Olsen Palmer analyzed the potential financial impact of the Landmark merger on certain projected financial results of Simmons. This analysis indicated that the Landmark merger is expected to be accretive to Simmons’s estimated earnings per share beginning in 2022. The analysis also indicated that the Landmark merger is expected to be accretive to tangible book value per share for Simmons and that Simmons would maintain capital ratios in excess of those required for Simmons to be considered well-capitalized under existing regulations. For all of the above analyses, the actual results achieved by Landmark and Simmons prior to and following the Landmark merger will vary from the projected results, and the variations may be material.

Olsen Palmer’s Compensation and Other Relationships with Landmark and Simmons. No limitations were imposed by the Landmark board of directors on Olsen Palmer with respect to the investigations made or procedures followed in rendering its opinion. Neither Olsen Palmer nor the individuals involved in providing the Olsen Palmer opinion has any present or contemplated future ownership interest in Landmark. Olsen Palmer is acting as Landmark’s financial advisor in connection with the Landmark merger and will receive a cash fee equal to 1.50% of the aggregate Landmark merger consideration, $150,000 of which became payable to Olsen Palmer with rendering of its opinion and the balance of which is contingent upon the closing of the Landmark merger. Landmark has also agreed to indemnify Olsen Palmer against certain claims and liabilities arising out of Olsen Palmer’s engagement and to reimburse Olsen Palmer for certain of its out-of-pocket expenses incurred in connection with Olsen Palmer’s engagement.

Olsen Palmer has not provided investment banking and financial advisory services to Landmark or Simmons during the two-year period prior to June 4, 2021, except with respect to the Landmark merger. Olsen Palmer may provide investment banking, financial advisory and other financial services to Landmark and/or Simmons in the future, for which Olsen Palmer may receive compensation.

Certain Prospective Financial Information

Simmons and Landmark 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 of any such projections. However, Landmark is including in this proxy statement/prospectus certain unaudited prospective financial information that was used by Olsen Palmer for the purpose of Olsen Palmer performing its financial analysis in connection with rendering its opinion to the Landmark board of directors, as described in the section entitled “—Opinion of Landmark’s Financial Advisor.” The unaudited prospective financial information of Landmark included in this proxy statement/prospectus, which we refer to as the Landmark prospective information, was made available by Landmark to Olsen Palmer. The Landmark prospective information was prepared solely by Landmark management and was not prepared, provided to, reviewed or approved by Simmons management or the Simmons board of directors. The unaudited prospective financial information of Simmons included in this proxy statement/prospectus, which we refer to as the Simmons prospective information (and, together with the Landmark prospective information, the prospective information) was not prepared, provided to, reviewed or approved by Landmark management, the Landmark board of directors, Simmons management or the Simmons board of directors. By inclusion of this prospective information, the respective managements and boards of directors of Landmark and Simmons, and Landmark’s financial advisor, assume no responsibility for the prospective information. The inclusion of this prospective information should not be regarded as an indication that any of Landmark, Simmons, Olsen Palmer, their

68

respective representatives or any other recipient of this prospective information considered, or now considers, it to be necessarily predictive of actual future results, or that it should be construed as financial guidance, and it should not be relied on as such.

The Landmark prospective information was prepared solely by Landmark management for internal use, and certain of the assumptions related to the impact of the merger were discussed between representatives of Simmons, Landmark and Olsen Palmer. The prospective information is subjective in many respects. While presented with numeric specificity, the prospective information reflects numerous estimates and assumptions made solely by Landmark management with respect to business, economic, market, competition, regulatory and financial conditions and matters specific to Landmark’s and Simmons’ respective businesses, all of which are difficult to predict and many of which are beyond Landmark’s and Simmons’ control. The prospective information reflects both assumptions solely by Landmark management as to certain business decisions that are subject to change and, in many respects, subjective judgment solely by Landmark management, and thus is susceptible to multiple interpretations and periodic revisions based on actual experience and business developments. No assurance can be given that the prospective information and the underlying estimates and assumptions will be realized. Actual results may differ materially from those set forth below, and important factors that may affect actual results and cause the prospective information to be inaccurate include, but are not limited to, risks and uncertainties relating to Landmark’s and Simmons’ respective businesses, industry performance, general business and economic conditions, competition, customer requirements and adverse changes in applicable laws, regulations or rules. For other factors that could cause actual results to differ, see the sections entitled “Risk Factors” and “Cautionary Statement Regarding Forward-Looking Statements” in this proxy statement/prospectus and in Simmons’ Annual Report on Form 10-K for the fiscal year ended December 31, 2020, as well as the other reports filed by Simmons with the SEC.

The prospective information was not prepared by Landmark management 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 prospective information requires significant estimates and assumptions that make it inherently less comparable to the similarly titled GAAP measures in Landmark’s and Simmons’ respective historical GAAP financial statements. Neither Landmark’s nor Simmons’ independent public accountants nor any other independent accountants, have compiled, examined or performed any procedures with respect to the prospective information contained herein, nor have they expressed any opinion or any other form of assurance on such information or its achievability.

Furthermore, the prospective information does not take into account any circumstances or events occurring after the date it was prepared. No assurance can be given that, had the prospective information been prepared as of the date of this proxy statement/prospectus, similar estimates and assumptions would be used. Neither Landmark nor Simmons intends to, and expressly disclaims any obligation to, make publicly available any update or other revision to the prospective information to reflect circumstances existing since their preparation or to reflect the occurrence of unanticipated events, even in the event that any or all of the underlying assumptions are shown to be in error, or to reflect changes in general economic or industry conditions. The prospective information does not take into account the possible financial and other effects on Landmark or Simmons of the Landmark merger and does not attempt to predict or suggest future results of the surviving company. The prospective information does not give effect to the Landmark merger, including the impact of negotiating or executing the Landmark merger agreement, the expenses that may be incurred in connection with consummating the Landmark merger, the potential synergies that may be achieved by the surviving company as a result of the Landmark merger, the effect on Landmark or Simmons of any business or strategic decision or action that has been or will be taken as a result of the Landmark merger agreement having been executed, or the effect of any business or strategic decisions or actions that would likely have been taken if the Landmark merger agreement had not been executed, but which were instead altered, accelerated, postponed or not taken in anticipation of

69

the Landmark merger. Further, the Landmark prospective information does not take into account the effect on Landmark of any possible failure of the Landmark merger to occur.

None of Landmark, Simmons, Olsen Palmer, or their respective affiliates, officers, directors, advisors or other representatives has made, makes or is authorized in the future to make any representation to any shareholder of Landmark or Simmons or other persons regarding Landmark’s or Simmons’ ultimate performance compared to the information contained in the prospective information or that the projected results will be achieved. The summary of the prospective information included below is not being included to influence your decision whether to vote for the Landmark merger proposal, but is being provided solely because it was used by Olsen Palmer in connection with rendering the Olsen Palmer opinion.

In light of the foregoing, and considering that the Landmark special meeting will be held many months after the prospective information was prepared, as well as the uncertainties inherent in any forecasted information, Landmark shareholders are cautioned not to place unwarranted reliance on such information, and all Landmark shareholders are urged to review the other information contained elsewhere in this proxy statement/prospectus for a description of Simmons’ and Landmark’s respective businesses as well as Simmons’ most recent SEC filings for a description of Simmons’ reported financial results. See the section entitled “Where You Can Find More Information.”

The following tables present the Landmark prospective information, prepared solely by Landmark management, and the Simmons prospective information, in each case, approved for Olsen Palmer’s use by the Landmark board of directors for Olsen Palmer’s financial analysis in connection with rendering the Olsen Palmer opinion to the Landmark board of directors, as described in the section entitled “—Opinion of Landmark’s Financial Advisor.”

Simmons’ Reasons for the Landmark Merger

In reaching its decision to adopt and approve the Landmark merger agreement, the Landmark merger and the other transactions contemplated by the Landmark merger agreement, the Simmons board of directors evaluated the Landmark merger agreement and the Landmark merger in consultation with Simmons’ management, as well as Simmons’ financial and legal advisors, and considered a number of factors, including, without limitation, the following material factors, which are not presented in order of priority:

| · | the anticipation that the Landmark merger is expected to enhance the scale and expand the footprint of the combined company in the attractive Tennessee banking market;

| · | each of Simmons’, Landmark’s and the combined company’s business, operations, financial condition, asset quality, earnings and prospects;

70

| · | the fact that Landmark’s business and operations complement those of Simmons and that the Landmark merger would result in a combined company with a diversified revenue stream from diversified geographic markets, a well-balanced portfolio and an attractive funding base;

| · | its existing knowledge of Landmark’s business and its review and discussions with Simmons’ management concerning the additional due diligence examination of Landmark conducted in connection with the Landmark merger;

| · | the perceived complementary nature of the cultures and the shared core technology operating systems of the two companies, which Simmons’ management believes should facilitate integration and implementation of the Landmark merger;

| · | the complementary branch networks of Simmons and Landmark;

| · | Landmark’s market position within the Tennessee banking market, particularly Landmark’s market share in the Memphis market;

| · | its understanding of the current and prospective environment in which Simmons and Landmark operate, including national, regional and local economic conditions, the competitive environment for financial institutions generally and the likely effect of these factors on Simmons both with and without the Landmark merger;

| · | the market for alternative merger or acquisition transactions in the financial services industry and the likelihood and timing of other material strategic transactions;

| · | the terms of the Landmark merger agreement, including the Landmark merger consideration, expected tax treatment, deal protection and termination fee provisions, which the Simmons board of directors reviewed with Simmons’ management and Simmons’ financial and legal advisors;

| · | Simmons’ successful operating and acquisition track record, specifically Simmons’ history of efficiently closing and integrating acquisitions;

| · | its belief that the Landmark merger is likely to provide substantial value to Simmons shareholders;

| · | the potential risks associated with achieving anticipated cost synergies and savings and successfully integrating Landmark’s business, operations and workforce with those of Simmons;

| · | the potential risk of diverting management attention and resources from the operation of Simmons’ business and towards the completion of the Landmark merger;

| · | certain anticipated Landmark merger-related costs;

| · | the regulatory and other approvals required in connection with the Landmark merger and the expectation that such regulatory approvals will be received in a timely manner and without the imposition of unacceptable conditions, including a burdensome condition;

| · | the potential risk of losing other acquisition opportunities while Simmons remains focused on completing the Landmark merger; and

| · | the nature and amount of payments and other benefits to be received by Landmark management in connection with the Landmark merger.

71

The foregoing discussion of the information and factors considered by the Simmons board of directors is not intended to be exhaustive, but, rather, includes the material factors considered by the Simmons board of directors. In reaching its decision to adopt and approve the Landmark merger agreement, the Landmark merger and the other transactions contemplated by the Landmark merger agreement, the Simmons 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 Simmons board of directors considered all these factors as a whole, and overall considered the factors to be favorable to, and to support, its determination to adopt and approve the Landmark merger agreement and the transactions contemplated thereby, including the Landmark merger.

This explanation of the Simmons board of directors’ reasoning and all other information presented in this section is forward-looking in nature and, therefore, should be read in light of the factors discussed in the section entitled “Cautionary Statement Regarding Forward-Looking Statements.”

Interests of Landmark’s Directors and Executive Officers in the Landmark Merger

In considering the recommendation of the Landmark board of directors that Landmark shareholders vote “FOR” the Landmark merger proposal, Landmark shareholders should be aware that some of Landmark’s executive officers and directors have interests in the Landmark merger, which may be considered to be different from, or in addition to, the interests of the Landmark shareholders generally. These interests are described below. The Landmark board of directors was aware of these interests and considered them, among other matters, in reaching its decision to approve the Landmark merger agreement, the Landmark merger and the other transactions contemplated by the Landmark merger agreement and to recommend that Landmark shareholders vote “FOR” the Landmark merger proposal.

Employment Agreements

Landmark has entered into employment agreements with the following executives which provide for severance obligations upon a termination of employment in connection with a change in control transaction: Charles Dickey, James Farrell and Mike Russell. These severance benefits provide for a severance payment equal to (1) 2.99 times the executive’s base salary, plus (2) an amount equal to the greater of the bonus paid to the executive for the previous year, if any, or the bonus that would have been paid to executive for the year in which the termination occurred, based on an annualized basis and in good faith, and (3) any unpaid vacation pay, expense reimbursements and other amounts due to the executive but not yet paid. In addition, for 36 months following the termination of employment, the executive and the executive’s spouse and dependents shall be eligible for a continuation of employee benefits or alternatively, if continuation of such benefits is not permitted under applicable law or regulations, cash in lieu of such benefits continuation. The employment agreements with each of Messrs. Dickey, Farrell, and Russell provide that if payments would constitute excess parachute payments within the meaning of Section 280G of the Code, payments will be reduced to the extent necessary in order to prevent payments from constituting an excess parachute payment. Whether any of the individual’s payments will be subject to reduction under this provision will depend on a number of factors, including each individual’s post-closing arrangements and compensation with Simmons. As of the date of this proxy statement/prospectus, Mr. Farrell has been offered employment by Simmons but Simmons intends that Mr. Farrell will remain eligible for the severance benefits described above even if he accepts the offered employment.

Stock Option Plan Acceleration

Landmark’s Non-Qualified Stock Option Plan provides that any unvested options automatically vest upon the occurrence of a change in control transaction. At the Landmark effective time, each Landmark stock option, whether vested or unvested, outstanding immediately prior to the Landmark effective time, will be canceled and converted into the right to receive from Simmons a cash payment equal to the difference, if positive, between (1) the fully diluted per share value and (2) the exercise price of such Landmark stock option.

72

Indemnification

The Landmark merger agreement provides that, for a period of six years after the Landmark effective time, Simmons will indemnify, defend and hold harmless each of the present and former directors or officers of Landmark against all liabilities arising out of actions or omissions arising out of such person’s services as director or officers of Landmark, or at Landmark’s request, of another corporation, partnership, joint venture, trust or other enterprise, occurring at or prior to the effective time to the fullest extent permitted under the Landmark charter and the Landmark bylaws in effect on the date of the Landmark merger agreement (subject to applicable law), including provisions relating to the advancement of expenses incurred in the defense of any litigation, provided that, in the case of an advancement of expenses, any indemnified party to whom expenses are advanced provides a written undertaking to repay such advances if it is ultimately determined that such indemnified party is not entitled to indemnification.

73

THE TRIUMPH MERGER

The following discussion contains material information regarding the Triumph merger. The discussion is subject to, and qualified in its entirety by reference to, the Triumph merger agreement, which is attached to this proxy statement/prospectus as Annex B and is incorporated by reference into this proxy statement/prospectus. The following is not intended to provide factual information about the parties or any of their respective subsidiaries or affiliates. This discussion does not purport to be complete and may not contain all of the information about the Triumph merger that is important to you. We urge you to read the Triumph merger agreement carefully and in its entirety, as it is the legal document governing the Triumph merger.

Terms of the Triumph Merger

Each of the Simmons board of directors and the Triumph board of directors approved the Triumph merger agreement. The Triumph merger agreement provides that, among other things, Triumph will merge with and into Simmons, with Simmons as the surviving corporation in the merger. Immediately following the Triumph merger, Triumph Bank will merge with and into Simmons Bank, with Simmons Bank as the surviving bank.

Based on the assumptions set forth below, at the Triumph effective time, each share of Triumph common stock that is issued and outstanding immediately prior to the Triumph effective time, excluding certain specified shares, will be converted into the right to receive, subject to possible adjustment, the Triumph merger consideration. In the aggregate, Simmons expects to issue approximately 4,164,839 shares of Simmons common stock and pay approximately $ 2,645,937.83 (minus the cash payment for outstanding Triumph stock options) to Triumph shareholders upon completion of the Triumph merger, subject to certain conditions and potential adjustments under the Triumph merger agreement. The Triumph merger consideration is based on the assumption that (i) 4,586,300 shares of Triumph common stock are issued and outstanding and (ii) 148,763 shares of Triumph common stock are subject to outstanding Triumph stock options with a weighted average exercise price of $ 18.67 , in each case, immediately prior to the Triumph effective time. In addition, we have assumed that the Triumph/Simmons average closing price is equal to $ 27.49 , which was the closing sales price of Simmons common stock on the last practicable trading day prior to printing this proxy statement/prospectus.

Simmons will not issue any fractional shares of Simmons common stock in the Triumph merger. Instead, a Triumph shareholder who would otherwise be entitled to a fractional share of Simmons common stock upon completion of the Triumph merger will receive, in lieu thereof, an amount in cash, rounded up to the nearest whole cent (without interest), determined by multiplying (i) the fraction of a share (rounded to the nearest thousandth when expressed in decimal form) of Simmons common stock that such shareholder would otherwise be entitled to receive by (ii) the Triumph/Simmons average closing price.

Triumph shareholders are being asked to approve the Triumph merger agreement, including the Triumph merger and all transactions contemplated thereby. See the section entitled “The Merger Agreements” for additional and more detailed information regarding the legal documents that govern the Triumph merger, including information about the conditions to consummation of the Triumph merger and the provisions for terminating or amending the Triumph merger agreement.

Background of the Triumph Merger

As part of the ongoing consideration and evaluation of Triumph’s long-term prospects and strategies over the years, the Triumph board of directors has regularly reviewed and assessed Triumph’s business strategies and objectives, including assessments of potentially available strategic growth opportunities, as part of Triumph’s efforts to enhance value for its shareholders and deliver the best possible services to its customers and communities.

The Triumph board of directors at its offsite retreat held on July 17, 2020, at Shelby Group International, Inc. d/b/a MCR Safety, which is located in Collierville, Tennessee, discussed possible next steps and growth of Triumph and Triumph Bank. During this Triumph board of directors’ retreat, business strategies and objectives were discussed as part of the continued effort to increase shareholder value and to deliver quality services to Triumph’s customers and to enhance the communities in which we live, work and play. Discussions ensued on the financial services markets in Memphis and Nashville, the regulatory environment, the economy generally and in these markets, Triumph’s ability to compete attracting talent, its pricing and service to Triumph’s customers.

The Triumph board of directors also discussed the benefits and risks to Triumph and its shareholders to continue to build organically through the opening of new branches or to consider combining with one or more financial institutions. The Triumph board of directors requested Mr. John A. Bobango of the law firm, Farris Bobango, PLC, Triumph’s counsel, which we refer to as Farris Bobango, and Mr. William J. Chase, Jr., Triumph’s President and Chief Executive Officer, to review and consider financial institutions to approach on behalf of Triumph for a discussion regarding potential opportunities. Over the next several days, Mr. Chase and Mr. Bobango discussed potential financial institutions to consider.

During July and August of 2020 and in the midst of the COVID-19 pandemic, Mr. Bobango had brief discussions with representatives of two financial institutions. The conversations were positive; however, after Mr. Chase and Mr. Bobango had discussions with Mr. Hilliard Crews, chair of the Triumph board of directors, and Mr. Mike McCarver, Triumph’s Executive Vice-President and Chief of Operations Officer, Mr. Chase and Mr. Bobango delayed further discussions due to the COVID-19 pandemic.

At the meeting of the Triumph board of directors on November 18, 2020, Mr. Bobango mentioned that now may be a better time to open discussions with financial institutions and Simmons would be a good candidate. Mr. Crews asked Mr. Bobango to connect with Mr. George Makris, Jr., Chairman and Chief Executive Officer of Simmons. On November 21, 2020, Mr. Bobango contacted Mr. Makris regarding the potential opportunity of a business combination with Simmons. Mr. Bobango and Mr. Makris agreed it would be useful to meet in person the next time Mr. Makris was in Memphis to explore a possible business combination.

Over the following three months Triumph entered into a mutual non-disclosure agreement with another financial institution, which resulted in preliminary discussions regarding a merger with Triumph. During this time, Triumph discussed, but did not enter into, a non-disclosure agreement with one additional financial institution.

On March 5, 2021, Mr. Makris called Mr. Bobango to inquire about Triumph’s interest in discussing a merger between the two companies. Mr. Bobango suggested Mr. Makris and other representatives of Simmons meet with representatives of Triumph.

On March 6, 2021, Mr. Bobango briefed Messrs. Crews, Chase and McCarver regarding his conversation with Mr. Makris and the opportunity of exploring a potential transaction with Simmons. Messrs. Crews, Chase and McCarver discussed that a meeting with Mr. Makris would be the next step and expressed their support for Mr. Bobango to contact Mr. Makris to arrange an in-person meeting between representatives of Triumph and Simmons to discuss a potential merger in greater detail. Over the next several days, Mr. Crews communicated with the other members of the Triumph board of directors regarding the initial discussions with Simmons.

On March 12, 2021, Messrs. Bobango, Crews, Chase and McCarver met with a representative of another financial institution to discuss potential strategic advantages of a merger.

On March 19, 2021, Messrs. Bobango, Crews, Chase and McCarver met with representatives of Simmons, which included Mr. Makris; Robert Fehlman, who was, at that time, Simmons’ Chief Financial Officer and Chief Operating Officer; and Stephen Massanelli, Simmons’ Chief Administrative Officer, which meeting was held at the offices of Farris Bobango in Memphis, Tennessee. The parties discussed the potential strategic advantages of a merger, each company’s philosophy, credit and underwriting, and

75

the financial and operational benefits of a combination of the two companies. At the meeting, the Triumph and Simmons representatives expressed interest in continuing discussions regarding a merger of the two companies. Following this meeting and over the next several days, Mr. Crews briefed other members of the Triumph board of directors on the discussions with Simmons.

From March 19, 2021 to March 24, 2021, Mr. Crews had informal discussions with the Triumph board of directors to outline the next steps with Simmons.

On March 24, 2021, at the Triumph board meeting, Mr. Crews discussed the meeting on March 19, 2021 with representatives from Simmons and the potential strategic advantages of a merger with Simmons. The Triumph board of directors also discussed the March 12, 2021 meeting of Triumph representatives with the other financial institution. After discussing the advantages and disadvantages of a strategic merger, the Triumph board of directors decided to pursue discussions with Simmons. The board of directors also discussed engaging Southard Financial to advise and issue a fairness opinion.

On March 26, 2021, Triumph and Simmons executed a customary mutual nondisclosure agreement in order to facilitate more detailed discussions of a potential business combination and reciprocal due diligence efforts.

On March 29, 2021, Simmons delivered an indication of interest to the Triumph board of directors to acquire Triumph for shares of Simmons common stock of approximately $132,047,500 in aggregate transaction value and based on the 20-trading day average closing price of Simmons common stock as of March 29, 2021.

On March 31, 2021, the Triumph board of directors held a special meeting to discuss the meeting with representatives of Simmons, the potential transaction with Simmons and the indication of interest delivered by Simmons. Mr. Bobango reviewed with the Triumph board of directors the directors’ fiduciary duties under Tennessee law and then discussed with the Triumph board of directors the terms for the potential transaction that were being discussed between Simmons and Triumph in the indication of interest. After a lengthy discussion, the Triumph board of directors expressed its support for continuing to explore the feasibility and potential benefits of a proposed transaction with Simmons and approved pursing a transaction with Simmons, provided Simmons submitted a revised bid with a “collar” based on the fluctuating price of the market value of Simmons common stock and a closing date early in the fourth quarter of 2021. The Triumph board of directors directed Messrs. Crews, Chase, McCarver and Bobango, to continue their discussions and negotiations with Simmons regarding such a transaction, and if the requested changes were made, authorized Mr. Crews to execute the revised indication of interest.

On April 1, 2021, Mr. Makris and Mr. Bobango discussed the terms set out in Simmons’ indication of interest and the changes requested by Triumph. Triumph requested a closing date in early October in the fourth quarter of 2021 and a right to terminate by Triumph if the price of the Simmons’ stock decreased beyond a certain level. Mr. Makris indicated he would discuss internally at Simmons.

On April 2, 2021, Simmons submitted a revised indication of interest that contained revisions acceptable to Triumph. The revised indication of interest was executed and dated by Mr. Crews on behalf of Triumph on April 2, 2021.

On April 10, 2021, Mr. McCarver communicated with its accounting advisor, Reynolds, Bone and Griesbeck, PLC, which we refer to as Reynolds, to assist with the financial analysis of the Triumph merger.

From April 13, 2021 to June 3, 2021, the parties engaged in mutual due diligence, including through a series of virtual due diligence meetings and telephone calls between the parties and their respective representatives to discuss relevant topics. Triumph made available to Simmons documents for their mutual due diligence, including through the use of a virtual data room. Triumph reviewed the public information available on Simmons and asked follow up questions to representatives of Simmons.

76

On May 10, 2021, Simmons delivered a first draft of the Triumph merger agreement to Farris Bobango. Between May 10, 2021 and June 1, 2021, the specific terms of the Triumph merger agreement were negotiated between the representatives of Simmons and Triumph and their respective outside counsel. During this period the representatives and their legal counsel also negotiated the terms of the Triumph voting agreements. During this period, Triumph and Simmons exchanged several additional drafts of the Triumph merger agreement and the related transaction documents, including the Triumph voting agreement. Additionally, during this time, Triumph continued to confer with Reynolds.

Throughout the day of June 2, 2021, the Triumph and Simmons management teams, with the assistance of the parties’ legal advisors, continued to finalize the Triumph merger agreement and Triumph voting agreements.

On June 3, 2021, the Triumph board of directors held a special meeting to review and discuss the potential transaction with Simmons, with representatives of Farris Bobango, Southard Financial, and Reynolds in attendance. Mr. Bobango updated the Triumph board of directors on the final negotiations with Simmons relating to the potential transaction and the final terms of the Triumph merger agreement, including the price terms, representations and warranties, negative covenants and closing conditions. Mr. Bobango then discussed with Triumph’s directors the terms of the Triumph voting agreements. The directors then asked management and Farris Bobango questions about the Triumph merger agreement. Following these questions from the Triumph board of directors, Mr. Bobango reviewed with the directors certain legal considerations, including the directors’ fiduciary duties in connection with their consideration of a potential transaction with Simmons.

Representatives of Southard Financial then reviewed and discussed with the Triumph board of directors, among other matters, certain preliminary financial analyses regarding the two companies and the financial aspects of the proposed transaction. Following the discussion, representatives of Southard Financial rendered to the Triumph board of directors its firm’s opinion, which was initially rendered orally and confirmed by a written opinion dated June 4, 2021, to the effect that, as of that date and subject to the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken as set forth in its opinion, the Triumph merger consideration was fair, from a financial point of view, to the holders of Triumph common stock as described in the section entitled “—Opinion of Triumph’s Financial Advisor.” For a description of Southard Financial’s opinion, please refer to the section entitled “—Opinion of Triumph’s Financial Advisor.”

There were further discussions, including comments and questions answered by Joseph Callicutt with Reynolds. After these discussions and considering various factors, including the interests of the Triumph shareholders, customers, employees and communities served by Triumph, as well as the factors described in the section entitled “—Triumph’s Reasons for the Triumph Merger and Recommendations of the Triumph Board of Directors,” the Triumph board of directors approved the Triumph merger agreement and the transactions contemplated thereby and determined that they were advisable and fair to and in the best interests of Triumph and its shareholders, and recommended that the Triumph shareholders approve and adopt the Triumph merger agreement.

On June 4, 2021, the Simmons board of directors held a meeting to consider the terms of the proposed Triumph merger and Triumph merger agreement. At the meeting, members of Simmons’ management reported on the status of due diligence and negotiations with Triumph. Also at the meeting, Simmons’ financial advisor reviewed with the Simmons board of directors financial aspects of the proposed Triumph merger. At the meeting, Simmons’ internal legal counsel reviewed with the Simmons board of directors its fiduciary duties and reviewed the key terms of the Triumph merger agreement and related agreements (including the Triumph voting agreements), as described elsewhere in this proxy statement/prospectus, including a summary of the provisions relating to governance of the combined company and the provisions relating to employee matters.

77

After considering the proposed terms of the Triumph merger agreement, the terms of the Triumph voting agreements, and taking into consideration the matters discussed during that meeting and prior meetings of the Simmons board of directors, including the factors described in the section entitled “—Simmons’ Reasons for the Triumph Merger,” the Simmons board of directors determined that the Triumph merger was consistent with Simmons’ business strategies and in the best interests of Simmons and Simmons shareholders and the Simmons board of directors voted to approve and adopt the Triumph merger agreement, the Triumph merger and the other transactions contemplated by the Triumph merger agreement.

Following the board meetings of Triumph and Simmons, on June 4, 2021, the Triumph merger agreement was signed by Triumph and Simmons and each of the directors and certain executive officers of Triumph signed the Triumph voting agreements. The transaction was announced in the morning of Monday, June 7, 2021, in a press release issued by Simmons.

Triumph’s Reasons for the Triumph Merger and Recommendation of the Triumph Board of Directors

After careful consideration, at a special meeting held on June 3, 2021, the Triumph board of directors (i) determined that the Triumph merger agreement and the transactions contemplated thereby, including the Triumph merger, are in the best interests of Triumph, its shareholders and other constituencies, (ii) declared the Triumph merger agreement advisable and (iii) approved the execution, delivery and performance of the Triumph merger agreement and the consummation of the transactions contemplated thereby, including the Triumph merger. Accordingly, the Triumph board of directors unanimously recommends that the Triumph shareholders vote “FOR” the Triumph merger proposal and “FOR” the Triumph adjournment proposal.

In reaching its decision to approve the Triumph merger agreement and the transactions contemplated thereby, including the Triumph merger, and to recommend that the Triumph shareholders approve the Triumph merger agreement, the Triumph board of directors evaluated the Triumph merger agreement, the Triumph merger and the other transactions contemplated by the Triumph merger agreement in consultation with Triumph’s management, as well as with Triumph’s financial and legal advisors, and considered a number of factors, including the following:

| · | each of Triumph’s and Simmons’ business, operations, financial condition, stock performance, asset quality, earnings and prospects. In reviewing these factors, including the information obtained through due diligence, the Triumph board of directors considered that Simmons’ and Triumph’s respective business, operations and risk profile complement each other and that the companies’ separate earnings and prospects, and the synergies and scale potentially available in the proposed transaction, create the opportunity for the combined company to leverage complementary and diversified revenue streams and to have superior future earnings and prospects compared to Triumph’s earnings and prospects on a stand-alone basis;

| · | the market value of Simmons common stock prior to the execution of the Triumph merger agreement, the prospects for future appreciation of Simmons common stock, and the history of dividends payable by Simmons to holders of Simmons common stock, and the trading liquidity of Simmons common stock;

| · | the fact that the exchange ratio, as may be adjusted, and the cash consideration to be paid to Triumph shareholders was believed by Triumph board of directors to be consistent with market practice for transactions of this type and with the strategic purpose of the transaction;

| · | Simmons’ broader products and services offerings, as well as its digital capabilities across its customer base;

78

| · | the perceived risks and uncertainties attendant to Triumph’s operation as an independent banking organization, including the risks and uncertainties related to competition in market areas of Triumph Bank, increased operating and regulatory costs, interest rate environments, and potentially increased capital requirements;

| · | the terms of the recent business combinations, including financial institutions, either announced or completed during the past year and the two quarters of this year in Tennessee and contiguous states and the effect of such combinations or competitive conditions and future opportunities in the Triumph market areas;

| · | Triumph’s familiarity of the current and prospective environment in the financial services industry, including economic conditions and the interest rate and regulatory environments, possible effects of scale, increased operating costs resulting from regulatory and compliance mandates, increasing competition from both nationwide banks and non-bank financial and financial technology firms, and current financial market conditions and the likely effects of these factors on Triumph’s and the combined company’s potential growth, development productivity and strategic options, and the likely effect of these factors on Triumph both with and without the proposed Triumph merger;

| · | Triumph’s views with respect to other strategic alternatives potentially available to Triumph, including continuing as a stand-alone company focused exclusively on organic growth, making smaller acquisitions of other banks, transformative transactions (including large acquisitions or a merger of equals) and a transaction involving the sale of Triumph and a transformative transaction with another potential acquiror or merger partner, and Triumph’s belief that a transaction with such other potential transaction partners would not deliver the financial and operational benefits that could be achieved in the proposed merger with Simmons;

| · | Simmons’ past record of integrating acquisitions and realizing expected financial and other benefits of such acquisitions;

| · | Triumph’s belief that the two companies’ corporate cultures are similar and compatible, which would facilitate integration and implementation of the transaction;

| · | synergies and positive impact to local communities and minimize the loss of customers and employees and to further diversify the operating risk of Triumph on a stand-alone basis;

| · | the fact that the Triumph shareholders will have an opportunity to vote on the approval of the Triumph merger agreement and the Triumph merger;

| · | the fact that Simmons intends to retain as many employees of Triumph as feasible;

| · | the fact that the Triumph shareholders would be entitled to appraisal or dissenters’ rights in connection with the Triumph merger;

| · | the impact of the Triumph merger on Triumph’s employees, including the compensation and employee benefits agreed to be provided by Simmons pursuant to the Triumph merger agreement;

| · | the expectation that the required regulatory approvals could be obtained in a timely fashion;

| · | the expectation the Triumph merger will be generally tax-free for United States federal income tax purposes for Triumph shareholders;

79

| · | the oral opinion of Southard Financial to the Triumph board of directors, subsequently confirmed in writing, to the effect that, as of June 4, 2021, the date of Southard Financial’s written opinion, and based upon and subject to the factors, qualifications and assumptions set forth in Southard Financial’s written opinion, the Triumph merger consideration was fair from a financial point of view to the holders (other than Simmons and its affiliates) of Triumph common stock, as more fully described below in the section entitled “—Opinion of Triumph’s Financial Advisor;” and

| · | the terms of the Triumph merger agreement, which Triumph reviewed with its legal counsel, including the representations, covenants, deal protection, closing conditions and termination provisions.

The Triumph board of directors also considered the potential risks related to the transaction but concluded that the anticipated benefits of combining with Simmons were likely to outweigh these risks substantially. These potential risks include:

| · | the potential for the value of the Triumph merger consideration to be received by Triumph shareholders to be adversely affected by a decrease in the trading price of Simmons’ common stock;

| · | the possible diversion of management and resources from other strategic opportunities and operational matters while working to implement the transaction and integrate the two companies;

| · | that Triumph’s directors and executive officers may have interests in the Triumph merger that are different from or in addition to those of its shareholders generally, as more fully described in the section entitled “—Interests of Triumph’s Directors and Executive Officers in the Triumph Merger;”

| · | the nature and amount of payments and other benefits to be received by Triumph’s management in connection with the Triumph merger pursuant to existing Triumph plans and compensation arrangements and the Triumph merger agreement;

| · | the risk of losing key Triumph employees during the pendency of the Triumph merger and thereafter;

| · | the restrictions on the conduct of Triumph’s business during the period between execution of the Triumph merger agreement and the consummation of the Triumph merger, which could delay or prevent Triumph from undertaking business opportunities that might arise or certain actions it might otherwise take regarding its operations, if not for the pendency of the Triumph merger;

| · | the potential effect of the Triumph merger on Triumph’s overall business, including its relationships with customers, employees, suppliers and regulators;

| · | the risk that the Triumph merger may not be completed despite the combined efforts of Triumph and Simmons or that completion may be delayed;

| · | the regulatory and other approvals required in connection with the Triumph merger and the merger of Triumph Bank with and into Simmons Bank and the risk that such regulatory approvals will not be received or will not be received in a timely manner or may impose burdensome or unacceptable conditions;

| · | the potential for legal claims challenging the Triumph merger;

| · | the potential risks associated with achieving anticipated efficiency improvements and cost reductions and savings and successfully integrating Triumph’s business, operations and workforce with those of Simmons;

80

| · | the fact that Triumph may be obligated to pay Simmons a termination fee of $6.5 million in certain circumstances, as more fully described in the sections entitled “The Merger Agreements—Termination of the Merger Agreements” and “The Merger Agreements—Termination Fees,” may deter others from proposing an alternative transaction that may be more advantageous to the Triumph shareholders; and

| · | the other risks described in the sections entitled “Risk Factors” and “Cautionary Statement Regarding Forward-Looking Statements.”

The foregoing discussion of the information and factors considered by the Triumph board of directors is not intended to be exhaustive, and may not include all of the material factors considered by the Triumph board of directors. In view of the variety of factors considered in connection with its consideration of the Triumph merger agreement and the other transactions contemplated thereby, including the Triumph merger and the complexity of these matters, the Triumph 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 above factors are not listed in any particular order of priority. The Triumph board of directors considered all these factors as a whole, including discussions with, and questioning of, Triumph’s senior management team and Triumph’s financial, legal advisors and accountants, in evaluating the Triumph merger agreement, the Triumph merger and the other transactions contemplated by the Triumph merger agreement.

For reasons set forth above, the Triumph board of directors determined that the Triumph merger agreement and the transactions contemplated by the Triumph merger agreement are advisable and fair to and in the best interests of Triumph and its shareholders, and approved the Triumph merger agreement and approved the Triumph merger and the other transactions contemplated by the Triumph merger agreement.

In considering the recommendation of the Triumph board of directors, you should be aware that certain directors and executive officers of Triumph may have interests in the Triumph merger that are different from, or in addition, to interests of the Triumph shareholders generally may create potential conflicts of interest. The Triumph board of directors was aware of these interests and considered them when evaluating and negotiating the Triumph merger agreement, the Triumph merger and the other transactions contemplated by the Triumph merger agreement, and in recommending to the Triumph shareholders that they vote in favor of the Triumph merger proposal. See the description of these interests in the section entitled “The Triumph Merger—Interests of Triumph’s Directors and Executive Officers in the Triumph Merger.”

This explanation of the reasoning of the Triumph board of directors and all other information presented in this section is forward-looking in nature and, therefore, should be read in light of the factors discussed in the section entitled “Cautionary Statement Regarding Forward-Looking Statements.”

For the reasons set forth above, the Triumph board of directors unanimously recommends the holders of Triumph common stock vote “FOR” the Triumph merger proposal and “FOR” the Triumph adjournment proposal.

Each of the directors and certain executive officers of Triumph, in their capacities as individuals, entered into Triumph voting agreements with Simmons and Triumph pursuant to which they agreed to vote “FOR” the Triumph merger proposal and “FOR” any other matters required to be approved by the Triumph shareholders in furtherance of the Triumph merger proposal. For more information regarding the Triumph voting agreements, please see the section entitled “The Merger Agreements—Voting Agreements.”

Opinion of Triumph’s Financial Advisor

Southard Financial was retained by the Triumph board of directors in connection with the Triumph merger. Southard Financial is a business valuation and strategic financial management consulting firm founded in 1987. The team of professionals at Southard Financial has extensive business valuation experience. Southard Financial provides a variety of valuation services, including fairness opinions, and Southard Financial offers valuations for financial institutions, corporations, and partnerships for various purposes. Since its founding, Southard Financial has provided thousands of valuation opinions for companies in 43 states. Triumph selected Southard Financial as its financial advisor on the basis of its experience and expertise in representing community banks in similar transactions and its familiarity with Triumph.

In connection with the Triumph merger, the Triumph board of directors has requested that Southard Financial render a written opinion, which we refer to as the Southard Financial opinion, regarding the fairness of the Triumph merger consideration. Southard Financial rendered to the Triumph board of directors its firm’s opinion, which was initially rendered orally and confirmed by a written opinion dated June 4, 2021, to the effect that, as of that date and subject to the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken as set forth in each such its opinion, the consideration to be paid by Simmons pursuant to the Triumph merger agreement was fair, from a financial point of view, to the Triumph shareholders. The full text of the Southard Financial opinion, which sets forth, among other things, the assumptions made, procedures followed, matters considered and limitations on the review undertaken by Southard Financial in rendering its opinion, is attached to this proxy statement/prospectus as Annex F. The summary of the Southard Financial opinion set forth herein is qualified in its entirety by reference to the full text of the opinion. Triumph shareholders should read the full text of the Southard Financial opinion carefully and in its entirety.

Southard Financial provided the Southard Financial opinion for the information of the Triumph board of directors (solely in its capacity as such) in connection with, and for purposes of, its consideration of the Triumph merger agreement, and the Southard Financial opinion only addressed whether the consideration to be paid by Simmons pursuant to the Triumph merger agreement was fair, from a financial point of view, to the Triumph shareholders. The Southard Financial opinion does not address any other terms or aspect of the Triumph merger agreement or the Triumph merger contemplated thereby. The Southard Financial opinion does not constitute a recommendation to the Triumph board of directors or any holder of Triumph common stock as to how the Triumph board of directors, such shareholder, or any other person should vote or otherwise act concerning the Triumph merger or any other matter. Southard Financial does not express any opinion as to the likely trading range of Simmons’ common stock following the Triumph merger, which may vary depending on numerous factors that generally impact the price of securities or on the financial condition of Simmons at that time.

In connection with rendering the Southard Financial opinion, Southard Financial reviewed and considered, among other things:

| · | a draft of the Triumph merger agreement, dated June 4, 2021;

| · | certain publicly available financial statements and other historical financial information of Triumph that Southard Financial deemed relevant;

| · | the publicly reported historical price and trading activity for Simmons common stock;

| · | a comparison of certain financial information for Triumph with similar financial institutions for which information is publicly available;

82

| · | the financial terms of certain recent business combinations in the banking industry (on a regional and nationwide basis), to the extent publicly available;

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

| · | other information, financial studies, analyses and investigations, financial, economic, and market criteria as Southard Financial considered relevant.

Southard Financial also discussed with certain members of Triumph management and its representatives the business, financial condition, results of operations, and prospects of Triumph.

In performing its review, Southard Financial relied upon the accuracy and completeness of all of the financial and other information available to and reviewed by Southard Financial. Southard Financial assumed such accuracy and completeness to render the Southard Financial opinion without any independent verification or investigation. Southard Financial relied on the assurances of Triumph management that they were not aware of any facts or circumstances that would make any of such information inaccurate or misleading. Southard Financial was not asked to and did not undertake independent verification of any of such information. Southard Financial did not assume any responsibility or liability for the accuracy or completeness thereof. Southard Financial 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 Triumph, nor was Southard Financial furnished with any such evaluations or appraisals. Southard Financial rendered no opinion or evaluation on the collectability of any assets or the future performance of any loans of Triumph. Southard Financial did not independently evaluate the adequacy of the allowance for loan losses of Triumph or the combined entity after the Triumph merger. Southard Financial did not review any individual credit files relating to Triumph. Southard Financial assumed that the allowances for loan loss provision at Triumph were adequate to cover such losses and would be sufficient on a pro forma basis for the combined entity.

Southard Financial also assumed, with Triumph’s consent, that (i) each of the parties to the Triumph merger agreement would comply in all material respects with all material terms of the Triumph merger agreement 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 required to be performed by such party under the 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 Triumph merger, no delay, limitation, restriction or condition would be imposed that would have an adverse effect on Triumph, Simmons or the Triumph merger or any related transactions, and (iii) the Triumph merger and any related transactions would be consummated in accordance with the terms of the Triumph merger 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 Triumph’s consent, Southard Financial relied upon the advice that Triumph received from its legal, accounting, and tax advisors as to all legal, accounting, and tax matters relating to the Triumph merger and the other transactions contemplated by the Triumph merger agreement. Accordingly, Southard Financial expressed no opinion as to any such matters.

The Southard Financial opinion was necessarily based on financial, economic, regulatory, market, and other conditions as in effect on, and the information made available to Southard Financial as of the date of the Southard Financial opinion. Events occurring after the date of the Southard Financial opinion could materially affect the Southard Financial opinion. Southard Financial has not undertaken to update, revise, reaffirm or withdraw the Southard Financial opinion or otherwise comment upon events occurring after the date of the Southard Financial opinion. Southard Financial expresses no opinion as to the trading value of Simmons common stock at any time or what the value of Simmons common stock would be once it is received by Triumph shareholders.

83

In rendering the Southard Financial opinion, Southard Financial performed a variety of financial analyses. The summary below is not a complete description of the analyses underlying the Southard Financial opinion or the presentation made by Southard Financial to the Triumph board of directors. However, it is a summary of all material analyses performed and presented by Southard Financial. To fully understand the financial analyses, these tables must be read together with the accompanying text. The tables alone do not constitute a complete description of the financial analyses. Also, no company included in Southard Financial’s comparative analyses described below is identical to Triumph, and no transaction is identical to the Triumph merger. Accordingly, an analysis of comparable companies or transactions involves complex considerations and judgments concerning differences in financial and operating characteristics of the companies and other factors that could affect the public trading values or merger transaction values, as the case may be, of Triumph and the companies to which they are being compared. In arriving at the Southard Financial opinion, Southard Financial did not attribute any particular weight to any analysis or factor that it considered. Rather, Southard Financial made qualitative judgments as to the significance and relevance of each analysis and factor. Southard Financial did not form an opinion as to whether any individual analysis or factor (positive or negative) considered in isolation supported or failed to support the Southard Financial opinion; instead, Southard Financial made its determination as to the fairness of the Triumph merger based on its experience and professional judgment after considering the results of all its analyses taken as a whole.

In performing its analyses, Southard Financial also made numerous assumptions concerning industry performance, business and economic conditions, and various other matters, many of which are beyond the control of Triumph. Southard Financial prepared its analyses solely for purposes of rendering the Southard Financial opinion. Estimates of the values of companies do not purport to be appraisals or necessarily reflect the prices at which companies or their securities may actually be sold. Such estimates are inherently subject to uncertainty, and actual values may be materially different. Accordingly, Southard Financial’s analyses do not necessarily reflect the value of Triumph common stock or the prices at which Triumph common stock may be sold at any time. The analyses of Southard Financial and the Southard Financial opinion were among many factors taken into consideration by the Triumph board of directors in making its determination to approve the Triumph merger agreement. The type and amount of consideration payable in the Triumph merger were determined through negotiations between Triumph and Simmons.

Based on the review conducted by Southard Financial, the implied Triumph merger pricing ratios are within the range of the whole bank pricing ratios shown above, supporting the fairness of the Triumph merger to the Triumph shareholders. It should be noted that Triumph’s earnings were well above historical levels in 2020 and 2021 year-to-date, largely due to the impact of Triumph Bank’s mortgage origination operations. Despite the substantial increase in earnings and the significant non-core mortgage origination income, Triumph’s implied price/earnings ratio is still near the median of the guideline transaction group reviewed by Southard Financial.

Present Value Analysis

Southard Financial performed an analysis of the present value of Triumph’s future earnings. The analysis is based on Triumph’s historical and projected financial results on a standalone basis with normalizing adjustments made by Southard Financial. Southard Financial utilized a single period model with earnings in the first year estimated as follows: (a) ongoing pre-tax return on average assets of 1.20% based on historical results and forecasted results, (b) forecasted 2021 average assets, (c) ongoing holding company net pre-tax expenses, and (d) an estimated tax rate of 26%.

88

As illustrated in the sensitivity analysis above, the valuation of Triumph ranged from $70.3 million to $140.6 million with a base case scenario valuation of $93.7 million. The consideration to be received by Triumph shareholders (approximately $132 million based on the closing price of Simmons common stock on June 4, 2021) generally represents a premium to the values shown above, supporting the fairness of the Triumph merger to the Triumph shareholders.

Liquidity

The proposed Triumph merger will create liquidity for the Triumph shareholders as the Triumph shareholders will own Simmons common stock following the Triumph merger, which is publicly traded stock with significant volume (median daily volume of approximately 470,000 shares in the year-to-date period ended June 4, 2021). The ability to hold publicly traded shares versus privately held stock is a significant positive factor for the Triumph shareholders.

Additional Considerations

The preparation of a fairness opinion is a complex process and is not susceptible to a partial analysis or summary description. Therefore, Southard Financial believes that its analyses must be considered as a whole and that selecting portions of its analyses would create an incomplete view of the process underlying the Southard Financial opinion without considering the analyses taken as a whole. In addition, Southard Financial considered the results of all such analyses and did not assign relative weights to any of the analyses, but instead made qualitative judgments as to the significance and relevance of each analysis and factor, so the ranges of valuations resulting from any particular analysis described above should not be taken to be the view of Southard Financial as to the actual value of Triumph.

In accordance with recognized professional ethics, Southard Financial’s professional fees for this service are not contingent upon the opinions expressed herein, and neither Southard Financial, nor any of its employees, has a present or intended financial relationship with or interest in Simmons, Triumph or Triumph Bank.

Certain Prospective Financial Information

Simmons and Triumph 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 of any such projections. However, Triumph is including in this proxy statement/prospectus certain unaudited prospective financial information that was made available by Triumph to Southard Financial for the purpose of Southard Financial performing its financial analysis in connection with rendering its opinion to the Triumph board of directors, as described in the section entitled “—Opinion of Triumph’s Financial Advisor.” This unaudited prospective financial information, which we refer to as the Triumph prospective information, was prepared solely by Triumph management and was not prepared, provided to, reviewed or approved by Simmons management or the Simmons board of directors. By inclusion of this information, the respective managements and boards of directors of Triumph and Simmons, and Triumph’s financial advisor, assume no responsibility for the Triumph prospective information. The inclusion of this information should not be regarded as an indication that any of Triumph, Simmons, Southard Financial, their respective representatives or any other recipient of this information considered, or now considers, it to be necessarily predictive of actual future results, or that it should be construed as financial guidance, and it should not be relied on as such.

The Triumph prospective information was prepared solely by Triumph management for internal use and is subjective in many respects. While presented with numeric specificity, the Triumph prospective information reflects numerous estimates and assumptions made solely by Triumph management with respect to business, economic, market, competition, regulatory and financial conditions and matters specific to Triumph’s business,

89

all of which are difficult to predict and many of which are beyond Triumph’s control. The Triumph prospective information reflects both assumptions solely by Triumph management as to certain business decisions that are subject to change and, in many respects, subjective judgment solely by Triumph management, and thus is susceptible to multiple interpretations and periodic revisions based on actual experience and business developments. No assurance can be given that the Triumph prospective information and the underlying estimates and assumptions will be realized. Actual results may differ materially from those set forth below, and important factors that may affect actual results and cause the Triumph prospective information to be inaccurate include, but are not limited to, risks and uncertainties relating to Triumph’s business, industry performance, general business and economic conditions, competition, customer requirements and adverse changes in applicable laws, regulations or rules. For other factors that could cause actual results to differ, see the sections entitled “Risk Factors” and “Cautionary Statement Regarding Forward-Looking Statements” in this proxy statement/prospectus.

The Triumph prospective information was not prepared by Triumph management 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 Triumph prospective information requires significant estimates and assumptions that make it inherently less comparable to the similarly titled GAAP measures in Triumph’s historical GAAP financial statements. Neither Triumph’s nor Simmons’ independent public accountants nor any other independent accountants, have compiled, examined or performed any procedures with respect to the Triumph prospective information contained herein, nor have they expressed any opinion or any other form of assurance on such information or its achievability.

Furthermore, the Triumph prospective information does not take into account any circumstances or events occurring after the date it was prepared. No assurance can be given that, had the Triumph prospective information been prepared as of the date of this proxy statement/prospectus, similar estimates and assumptions would be used. Neither Triumph nor Simmons intends to, and expressly disclaims any obligation to, make publicly available any update or other revision to the Triumph prospective information to reflect circumstances existing since their preparation or to reflect the occurrence of unanticipated events, even in the event that any or all of the underlying assumptions are shown to be in error, or to reflect changes in general economic or industry conditions. The Triumph prospective information does not take into account the possible financial and other effects on Triumph of the Triumph merger and does not attempt to predict or suggest future results of the surviving company. The Triumph prospective information does not give effect to the Triumph merger, including the impact of negotiating or executing the Triumph merger agreement, the expenses that may be incurred in connection with consummating the Triumph merger, the potential synergies that may be achieved by the surviving company as a result of the Triumph merger, the effect on Triumph of any business or strategic decision or action that has been or will be taken as a result of the Triumph merger agreement having been executed, or the effect of any business or strategic decisions or actions that would likely have been taken if the Triumph merger agreement had not been executed, but which were instead altered, accelerated, postponed or not taken in anticipation of the Triumph merger. Further, the Triumph prospective information does not take into account the effect on Triumph of any possible failure of the Triumph merger to occur.

None of Triumph, Simmons, Southard Financial, or their respective affiliates, officers, directors, advisors or other representatives has made, makes or is authorized in the future to make any representation to any shareholder of Triumph or Simmons or other persons regarding Triumph’s ultimate performance compared to the information contained in the Triumph prospective information or that the projected results will be achieved. The summary of the Triumph prospective information included below is not being included to influence your decision whether to vote for the Triumph merger proposal, but is being provided solely because it was made available to Southard Financial in connection with the Triumph merger.

90

In light of the foregoing, and considering that the Triumph special meeting will be held many months after the Triumph prospective information was prepared, as well as the uncertainties inherent in any forecasted information, Triumph shareholders are cautioned not to place unwarranted reliance on such information, and all Triumph shareholders are urged to review the other information contained elsewhere in this proxy statement/prospectus for a description of Simmons’ and Landmark’s respective businesses as well as Simmons’ most recent SEC filings for a description of Simmons’ reported financial results. See the section entitled “Where You Can Find More Information.”

The following tables present the Triumph prospective information, which was prepared solely by Triumph management and approved for Southard Financial’s use by the Triumph board of directors for Southard Financial’s financial analysis in connection with rendering the Southard Financial opinion to the Triumph board of directors, as described in the section entitled “—Opinion of Triumph’s Financial Advisor.”

Simmons’ Reasons for the Triumph Merger

In reaching its decision to adopt and approve the Triumph merger agreement, the Triumph merger and the other transactions contemplated by the Triumph merger agreement, the Simmons board of directors evaluated the Triumph merger agreement and the Triumph merger in consultation with Simmons’ management, as well as Simmons’ financial and legal advisors, and considered a number of factors, including, without limitation, the following material factors, which are not presented in order of priority:

| · | the anticipation that the Triumph merger is expected to enhance the scale and expand the footprint of the combined company in the attractive Tennessee banking market;

| · | each of Simmons’, Triumph’s and the combined company’s business, operations, financial condition, asset quality, earnings and prospects;

| · | the fact that Triumph’s business and operations complement those of Simmons and that the Triumph merger would result in a combined company with a diversified revenue stream from diversified geographic markets, a well-balanced portfolio and an attractive funding base;

| · | its existing knowledge of Triumph’s business and its review and discussions with Simmons’ management concerning the additional due diligence examination of Triumph conducted in connection with the Triumph merger;

| · | the perceived complementary nature of the cultures and the shared core technology operating systems of the two companies, which Simmons’ management believes should facilitate integration and implementation of the Triumph merger;

| · | the complementary branch networks of Simmons and Triumph;

91

| · | Triumph’s market position within the Tennessee banking market, particularly Triumph’s market share in the Nashville market;

| · | its understanding of the current and prospective environment in which Simmons and Triumph operate, including national, regional and local economic conditions, the competitive environment for financial institutions generally and the likely effect of these factors on Simmons both with and without the Triumph merger;

| · | the market for alternative merger or acquisition transactions in the financial services industry and the likelihood and timing of other material strategic transactions;

| · | the terms of the Triumph merger agreement, including the Triumph merger consideration, expected tax treatment, deal protection and termination fee provisions, which the Simmons board of directors reviewed with Simmons’ management and Simmons’ financial and legal advisors;

| · | Simmons’ successful operating and acquisition track record, specifically Simmons’ history of efficiently closing and integrating acquisitions;

| · | its belief that the Triumph merger is likely to provide substantial value to Simmons shareholders;

| · | the potential risks associated with achieving anticipated cost synergies and savings and successfully integrating Triumph’s business, operations and workforce with those of Simmons;

| · | the potential risk of diverting management attention and resources from the operation of Simmons’ business and towards the completion of the Triumph merger;

| · | certain anticipated Triumph merger-related costs;

| · | the regulatory and other approvals required in connection with the Triumph merger and the expectation that such regulatory approvals will be received in a timely manner and without the imposition of unacceptable conditions, including a burdensome condition;

| · | the potential risk of losing other acquisition opportunities while Simmons remains focused on completing the Triumph merger; and

| · | the nature and amount of payments and other benefits to be received by Triumph management in connection with the Triumph merger.

The foregoing discussion of the information and factors considered by the Simmons board of directors is not intended to be exhaustive, but, rather, includes the material factors considered by the Simmons board of directors. In reaching its decision to adopt and approve the Triumph merger agreement, the Triumph merger and the other transactions contemplated by the Triumph merger agreement, the Simmons 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 Simmons board of directors considered all these factors as a whole, and overall considered the factors to be favorable to, and to support, its determination to adopt and approve the Triumph merger agreement and the transactions contemplated thereby, including the Triumph merger.

This explanation of the Simmons board of directors’ reasoning and all other information presented in this section is forward-looking in nature and, therefore, should be read in light of the factors discussed in the section entitled “Cautionary Statement Regarding Forward-Looking Statements.”

Interests of Triumph’s Directors and Executive Officers in the Triumph Merger

In considering the recommendation of the Triumph board of directors that Triumph shareholders vote “FOR” the Triumph merger proposal, Triumph shareholders should be aware that some of Triumph’s executive officers and directors have interests in the Triumph merger, which may be considered to be different from, or in addition to, the interests of the Triumph shareholders generally. These interests are described below. The Triumph board of directors was aware of these interests and considered them, among other matters, in reaching its decision to approve the Triumph merger agreement, the Triumph merger and the other transactions contemplated by the Triumph merger agreement and to recommend that Triumph shareholders vote “FOR” the Triumph merger proposal.

Employment Agreements

Seven executive officers of Triumph are party to employment agreements with Triumph that contain change of control payments: William J. Chase, Jr., Michael J. McCarver, Scott A. Forman, Steven C. Mitchener, John N. Brignole, David Umsted, and William C. Menkel. Under these employment agreements, the Triumph merger would constitute a change in control, as defined in the agreements. Without a change in control, these seven executives are entitled to certain defined severance benefits if they are terminated by Triumph without cause, as cause is defined in their respective employment agreements. In the event of termination (without a change in control), (i) Messrs. Chase, McCarver, Brignole, Umsted and Menkel would be entitled to receive compensation equal to their annual base salary and 12 months of continued health coverage, and (ii) Messrs. Forman and Mitchener would be entitled to receive compensation equal to one-half of their annual base salary and six months of continued health coverage. In the event of resignation for good reason (without a change in control), (i) Mr. Menkel would be entitled to receive compensation equal to his annual base salary and 12 months of continued health coverage and (ii) Mr. Mitchener would be entitled one-half of his annual base salary and six months of continued health coverage. Upon a change of control, the seven executives may be due certain payments based on the terms and conditions of their employment agreements, as follows.

William J. Chase, Jr., Michael J. McCarver and William C. Menkel. In the event of a change of control, if any of Messrs. Chase, McCarver or Menkel is offered a new employment agreement that contains a “material reduction,” which is defined as (i) a material reduction in the executive’s duties, title, authority or responsibilities, and (ii) a reduction in the base salary of the executive, or (iii) a relocation of the executive’s principal place of work to more than 25 miles from a specified location in Tennessee, then he is due a payment equal to his annual base salary and 12 months of continued health coverage. If any of Messrs. Chase, McCarver or Menkel is terminated in anticipation of the change in control or is not offered a position after the change in control, then he is due a payment equal to two times his annual base salary in the case of Messrs. Chase and McCarver, and equal to his annual base salary in the case of Mr. Menkel, as well as 12 months of continued health coverage. Mr. Chase was offered a position that included a material reduction and as a result he will be eligible for a payment equal to his annual base salary and 12 months of continued health coverage.

David Umsted, Scott A. Forman and John N. Brignole. In the event of a termination without cause or resignation for good reason (either before or after a change of control), each of Messrs. Umsted, Forman and Brignole is entitled to receive 12 months of continued health coverage, Mr. Forman is entitled to receive a payment equal to one-half of his annual base salary and each of Messrs. Umsted and Brignole is entitled to receive a payment equal to his annual base salary. In the event of a change in control, (i) each of Mr. Brignole and Mr. Umsted is due a payment equal to one-half of his annual base salary and 12 months of continued health coverage, unless he is offered employment on at least similar terms and conditions as his current employment and he refuses to accept such employment, in which case, no change in control payment or continued benefits will be due and (ii) Mr. Forman is due a payment equal to one-half of his annual base salary and 12 months of continued health coverage, unless he is offered employment on at least similar terms and conditions as his current employment and he refuses to accept such employment, in which case, no change in control payment will be due. If any of Messrs. Umsted, Forman or Brignole is terminated in anticipation of the change in control, then he is due a payment equal to one-half of his annual base salary plus an amount equal to his pro-rata bonus earned through the date of termination and 12 months of continued health coverage.

Steven C. Mitchener. In the event of a change of control, Mr. Mitchener is entitled to receive a payment equal to one-half of his annual base salary if he is terminated in anticipation of the change in control or is not offered a position after the change in control that includes the same base salary, comparable duties, title authority and responsibilities.

93

As of the date of this proxy statement/prospectus, John Bobango has been offered an advisory position with Simmons for 18 months following the closing of the Triumph merger for a fee of $660,000.

The Triumph merger will also act to trigger accelerated vesting of outstanding options held by the seven executive officers named above (and others) under the Triumph 2006 Incentive and Non-Qualified Stock Option Plan, Triumph 2012 Incentive and Non-Qualified Stock Option Plan, and the Triumph 2017 Incentive and Non-Qualified Stock Option Plan. The amounts of the options will not be affected by the Triumph merger, but the timing of the vesting of the options will be accelerated.

Incentive Plans and Stock Options

The Triumph merger will trigger the vesting of all issued and outstanding options, including any options issued to executives and directors of Triumph, under the Triumph 2006 Incentive and Non-Qualified Stock Option Plan, Triumph 2012 Incentive and Non-Qualified Stock Option Plan, or Triumph 2017 Incentive and Non-Qualified Stock Option Plan.

Under the terms of the Triumph merger agreement, at the Triumph effective time, each Triumph stock option, whether vested or unvested, that is outstanding and unexercised immediately prior to the Triumph effective time will be canceled and converted into the right to receive from Simmons a cash payment per option share equal to the difference between (1) the fully diluted per share value and (2) the exercise price of such Triumph stock option.

Indemnification

The Triumph merger agreement provides that, for a period of six years after the Triumph effective time, Simmons will indemnify, defend and hold harmless each of the present and former directors or officers of Triumph and its subsidiaries against all liabilities arising out of actions or omissions arising out of such person’s services as director or officer of Triumph, or at Triumph’s request, of another corporation, partnership, joint venture, trust or other enterprise, occurring at or prior to the Triumph effective time to the fullest extent permitted under the Triumph charter and the Triumph bylaws in effect on the date of the Triumph merger agreement (subject to applicable law), including provisions relating to the advancement of expenses incurred in the defense of any litigation, provided that, in the case of an advancement of expenses, any indemnified party to whom expenses are advanced provides a written undertaking to repay such advances if it is ultimately determined that such indemnified party is not entitled to indemnification.

94

THE MERGERS

Board of Directors and Management of Simmons and Simmons Bank After the Mergers

The directors and officers of Simmons and Simmons Bank immediately prior to the effective time of each of the mergers will serve as the directors and officers of the surviving corporation and surviving bank from and after the effective time of each of the mergers in accordance with the bylaws of the surviving corporation and surviving bank. Information about the current members of the Simmons board of directors can be found in the documents listed in the section entitled “Where You Can Find More Information.”

Public Trading Markets

Simmons common stock is listed for trading on Nasdaq under the symbol “SFNC.” Neither Landmark common stock nor Triumph common stock is listed for trading on any securities exchange and there is no established public trading market for either Landmark common stock or Triumph common stock.

Under the merger agreements, Simmons will cause the shares of Simmons common stock to be issued in the mergers to be approved for listing on Nasdaq, subject to notice of issuance, and the merger agreements provide that Simmons and Landmark, in the case of the Landmark merger agreement, and Simmons and Triumph, in the case of the Triumph merger agreement, will not be required to complete the applicable merger if such shares have not been authorized for listing on Nasdaq.

Accounting Treatment

The mergers will be accounted for as acquisitions by Simmons using the acquisition method of accounting in accordance with FASB ASC Topic 805, “Business Combinations.” The result of this is that (1) the recorded assets and liabilities of Simmons will be carried forward at their recorded amounts, (2) Simmons historical operating results will be unchanged for the prior periods being reported on, and (3) the assets and liabilities of each of Landmark and Triumph will be adjusted to fair value at the respective dates Simmons assumes control of the combined entity, or the respective merger dates. In addition, all identifiable intangibles will be recorded at fair value and included as part of the net assets acquired. The amount by which the purchase price for each merger, consisting of the value of cash and shares of Simmons common stock to be issued to former Landmark and Triumph shareholders, respectively, and the value of cash and shares of Simmons common stock to be issued to former holders of Landmark and Triumph equity awards, respectively, exceeds the fair value of the net assets, including identifiable intangibles, of Landmark and Triumph, respectively, at the applicable merger date will be reported as goodwill. In accordance with current accounting guidance, goodwill is not amortized and will be evaluated for impairment at least annually. Identified intangibles will be amortized over their estimated lives. Further, the acquisition method of accounting results in the operating results of each of Landmark and Triumph being included in the operating results of Simmons from the applicable merger date going forward.

Appraisal and Dissenters’ Rights

Dissenters’ rights with respect to Landmark common stock and Triumph common stock are governed by the TBCA. Under the TBCA, Landmark shareholders as of the Landmark record date and Triumph shareholders as of the Triumph record date have the right to dissent from the Landmark merger or the Triumph merger, respectively, and to receive payment in cash for the fair value of such holders’ shares of Landmark common stock or Triumph common stock, respectively, in lieu of the consideration such holders would otherwise be entitled to pursuant to the applicable merger agreement. These rights are known as “appraisal rights” or “dissenters’ rights.” However, it is a condition to Simmons’ obligations under the Landmark merger agreement and the Triumph merger agreement that holders of not more than five percent of outstanding Landmark common stock or Triumph common stock, respectively, demand, properly and in writing, appraisal for such shares of outstanding common

95

stock. No Landmark shareholder or Triumph shareholder dissenting from the applicable merger will be entitled to the applicable merger consideration or any dividends or other distributions unless and until such shareholder fails to perfect or effectively withdraws or loses his or her right to dissent from the applicable merger agreement. Subject to the terms of the merger agreements, the Landmark board of directors or the Triumph board of directors could elect to terminate the applicable merger agreement even if it is approved by shareholders, thus cancelling dissenters’ rights.

The following is intended as a brief summary of the material provisions of the Tennessee statutory procedures required to be followed by a Landmark shareholder or Triumph shareholder in order to dissent from the Landmark merger or the Triumph merger, respectively, and perfect appraisal rights. This summary, however, is not a complete statement of all applicable requirements and is qualified in its entirety by reference to Section 48-23-101 through Section 48-23-302 of the TBCA, the full text of which appears in Annex G to this proxy statement/prospectus. Strict compliance with the statutory procedures is required to perfect appraisal rights under the TBCA. Neither Landmark nor Triumph can give any Landmark shareholder or Triumph shareholder legal advice. To completely understand this law, each Landmark shareholder and Triumph shareholder should read carefully Annex G to this proxy statement/prospectus in its entirety, and may want, and Landmark and Triumph encourage any Landmark shareholder or Triumph shareholder, as applicable, seeking to dissent, to consult with such shareholder’s legal advisor. Any Landmark shareholder or Triumph shareholder who wishes to dissent should not send in a signed proxy unless such shareholder marks such shareholder’s proxy to vote against the Landmark merger or the Triumph merger, as applicable, or such shareholder will lose the right to dissent.

In order to perfect dissenters’ rights with respect to the Landmark merger or the Triumph merger, a shareholder must satisfy each of the following conditions:

| · | deliver to Landmark or Triumph, as applicable, before the vote at the applicable special meeting is taken, written notice of such shareholder’s intent to demand payment for such shareholder’s shares of Landmark common stock or Triumph common stock if the applicable merger is effectuated;

| · | not vote, or cause or permit to be voted, such shareholder’s shares of Landmark common stock or Triumph common stock in favor of the applicable merger; and

| · | demand payment and deposit with Simmons such shareholder’s stock certificates representing such shareholder’s shares of Landmark common stock or Triumph common stock, as applicable, in accordance with the terms of the written dissenters’ notice sent by Simmons following the merger, which notice will set forth where and when to send the payment demand.

Such written notification should be delivered either in person or by mail (certified mail, return receipt requested, being the recommended form of transmittal) to Landmark, with respect to Landmark shareholders, or Triumph, with respect to Triumph shareholders, at the following respective addresses:

Memphis, Tennessee 38119

Attention: Michael J. McCarver

Telephone: (901) 333-8802

Landmark and Triumph urge any Landmark shareholder or Triumph shareholder, respectively, who wishes to dissent to act carefully. Neither Landmark nor Triumph can, and neither Landmark nor Triumph does, accept the risk of late or undelivered notices or demands. A dissenting Landmark shareholder or Triumph shareholder may call the applicable telephone number above to receive confirmation that such shareholder’s notice or demand has been received. If such shareholder’s notices or demands are not timely received by Landmark or Triumph, as applicable, then such shareholder will not be entitled to exercise his or her dissenters’ rights. Landmark shareholders and Triumph shareholders bear the risk of non-delivery and of untimely delivery. If the applicable merger is completed, a shareholder who fails to satisfy delivery requirements will have no appraisal rights with respect to such holder’s shares of Landmark common stock or Triumph common stock, as applicable.

ANY LANDMARK SHAREHOLDER OR TRIUMPH SHAREHOLDER WHO WISHES TO EXERCISE DISSENTERS’ RIGHTS OR WHO WISHES TO PRESERVE SUCH SHAREHOLDER’S RIGHT TO DO SO SHOULD REVIEW ANNEX G CAREFULLY AND CONSULT SUCH SHAREHOLDER’S LEGAL ADVISOR. FAILURE TO TIMELY AND PROPERLY COMPLY WITH THE PROCEDURES SET FORTH THEREIN WILL RESULT IN THE LOSS OF SUCH RIGHTS. INVESTMENT BANKER OPINIONS AS TO THE FAIRNESS, FROM A FINANCIAL POINT OF VIEW, OF THE CONSIDERATION PAYABLE IN TRANSACTIONS SUCH AS THE MERGERS ARE NOT OPINIONS AS, AND DO NOT ADDRESS IN ANY RESPECT, FAIR VALUE UNDER THE TBCA.

No later than ten days after the completion of the applicable merger, Simmons, as the surviving corporation of such merger, must deliver to each Landmark shareholder and Triumph shareholder who filed a notice of intent to demand payment for such shareholder’s shares a written appraisal notice and an election form that, among other things:

| · | specifies the first date of any public announcement of the principal terms of the applicable proposed merger;

| · | requires the dissenting shareholder to certify whether beneficial ownership of their shares of Landmark common stock or Triumph common stock, as applicable, was acquired before the date of the public announcement regarding the applicable merger;

| · | requires the dissenting shareholder to certify that such shareholder did not vote in favor of or consent to the applicable merger; and

| · | states:

| o | where to return the completed appraisal election form and such shareholder’s stock certificates representing such shareholder’s shares of Landmark common stock or Triumph common stock, as applicable, for deposit, and the date by which each must be received by Simmons or its agent, which may not be fewer than 40 nor more than 60 days after the written appraisal notice is sent to shareholders, and that such shareholder shall have waived the right to demand payment with respect to such shares unless the form is received by Simmons or its agent by such specified date;

| o | Simmons’s estimate of the fair value of the shares of Landmark common stock or Triumph common stock, as applicable; and

97

| o | that, if requested in writing, Simmons will provide to the shareholder so requesting, within ten days after the date set for receipt by Simmons of the appraisal election form, the number of Landmark shareholders or Triumph shareholders, as applicable, who return the forms by such date and the total number of shares owned by them;

and would need to be accompanied by a copy of Section 48-23-101 through Section 48-23-302 of the TBCA, if Landmark, Triumph or Simmons, as applicable, had not previously sent a copy of that chapter to the shareholder. The full text of Section 48-23-101 through Section 48-23-302 of the TBCA appears in Annex G to this proxy statement/prospectus.

Upon receipt of such notice, dissenting shareholders would become entitled to receive payment of their shares of Landmark common stock or Triumph common stock, as applicable, when they:

| · | demand payment;

| · | certify whether such shareholder acquired the shares of Landmark common stock or Triumph common stock, as applicable, prior to the date of the first public announcement of the applicable merger; and

| · | deposit with Simmons such shareholder’s stock certificates representing such shareholder’s shares of Landmark common stock or Triumph common stock, as applicable, in accordance with the instructions set forth in the notice.

Such shareholder retains all other rights of a shareholder until these rights are canceled or modified by the effectuation of the applicable merger. A shareholder who does not demand payment or deposit such shareholder’s share certificates where required, each by the date set in the dissenters’ notice, is not entitled to payment for such shareholder’s Landmark common stock or Triumph common stock, as applicable.

Upon receipt of the payment demand described above or the date the applicable merger is effectuated, whichever is later, Simmons will pay to each Landmark shareholder and Triumph shareholder who complied with the requirements of the TBCA the amount Simmons estimates to be the fair value of each Landmark shareholder’s and Triumph shareholder’s shares, plus accrued interest. The payment will be accompanied by:

| · | Simmons’ balance sheet as of the end of a fiscal year ending not more than 16 months before the date 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;

| · | an estimate of the fair value of the shares, which shall equal or exceed the estimate given in the dissenters’ notice;

| · | an explanation of how the interest was calculated;

| · | a statement of the dissenter’s right to demand payment in case of disagreements between the dissenter and Simmons regarding fair value; and

| · | a copy of Section 48-23-101 through Section 48-23-302 of the TBCA, if Landmark, Triumph or Simmons, as applicable, had not previously sent a copy of that chapter to the shareholder. The full text of Section 48-23-101 through Section 48-23-302 of the TBCA is attached as Annex G to this proxy statement/prospectus.

98

A shareholder who does not demand payment or deposit the shareholder’s stock certificates where required, each by the date set in the dissenters’ notice, is not entitled to payment for such shareholder’s shares. A demand for payment filed by a dissenting shareholder may not be withdrawn without Landmark’s or Triumph’s consent, as applicable, or, after the completion of the applicable merger, Simmons’s consent. Upon valid withdrawal from the appraisal process, the right of such shareholder to be paid the fair value of such shareholder’s shares will cease, and such shareholder will be reinstated as a shareholder and will be entitled to receive the Landmark merger consideration or the Triumph merger consideration, as applicable.

A dissenting shareholder who is dissatisfied with Simmons’s estimate of the fair value of the shares of Landmark common stock or Triumph common stock, as applicable, must notify Simmons of such shareholder’s estimate of the fair value of such shareholder’s shares and demand payment of that estimate plus interest in the appraisal election form within one month after Simmons made or offered payment for such shareholder’s shares. A dissenting shareholder who fails to notify Simmons in writing of the shareholder’s demand to be paid its stated estimate of the fair value of the shares plus interest within the required time period waives the right to demand payment and will be entitled only to the payment offered by Simmons in the appraisal election form.

If a demand for payment from a dissenting shareholder who is dissatisfied with Simmons’s estimate of the fair value of such holder’s shares remains unsettled, then within two months after receipt of a payment demand from such shareholder, Simmons must petition a court of record having equity jurisdiction in the county where Simmons’s principal office is located, to determine the fair value of the shares and accrued interest. Simmons will be required to make all dissenting shareholders whose demands remain unsettled, parties to the proceeding. If Simmons does not commence the proceeding within the two-month period, it must pay each dissenting shareholder whose demand remains unsettled the amount demanded by such shareholder.

Failure to strictly comply with the applicable TBCA provisions will result in the loss of the right of appraisal. The right of a dissenting shareholder to be paid the fair value for such shareholder’s shares will also cease if the applicable merger agreement is terminated for any reason.

THE PRECEDING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY THE TEXT OF THE APPRAISAL PROVISIONS OF TBCA SECTION 48-23-101 THROUGH SECTION 48-23-302. A COPY OF THESE STATUTES IS ATTACHED TO THIS PROXY STATEMENT/PROSPECTUS AS ANNEX G AND IS INCORPORATED HEREIN BY REFERENCE. TO THE EXTENT THERE ARE ANY INCONSISTENCIES BETWEEN THE FOREGOING SUMMARY AND THE APPLICABLE PROVISIONS OF THE TBCA, THE TBCA WILL CONTROL.

Regulatory Approvals Required for the Mergers and the Triumph Bank Merger

Completion of each of the Landmark merger, the Triumph merger, and the Triumph Bank merger is subject to prior receipt of certain approvals and consents required to be obtained from, or waived by, applicable governmental and regulatory authorities, without materially burdensome conditions or requirements being imposed by any governmental authority as part of a regulatory approval. Subject to the terms and conditions of the merger agreements, Simmons and Landmark, in the case of the Landmark merger agreement, and Simmons and Triumph, in the case of the Triumph merger agreement, have agreed to use their reasonable best efforts and cooperate to promptly prepare and file all necessary documentation and to obtain as promptly as practicable all regulatory approvals necessary or advisable to complete the transactions contemplated by the merger agreements. These approvals include, among others, approval from the Federal Reserve Board and the ASBD, with respect to each of the Landmark merger and the Triumph Bank merger. No assurance can be given that the necessary regulatory approvals will be received in time to effect the mergers in the fourth quarter of 2021.

99

Federal Reserve Board

Under Federal Reserve Board regulations, the transactions contemplated in the Landmark merger agreement are exempt from the requirement to submit an application to the Federal Reserve Board pursuant to the BHC Act.

The transactions contemplated by the Triumph merger agreement are subject to review and approval by the Federal Reserve Board pursuant to the BHC Act. Simmons has submitted to the Federal Reserve Board a request for waiver of this approval requirement with respect to the Triumph merger. If the Federal Reserve Board does not grant this waiver request, Simmons will be required to submit an application under Section 3 of the BHC Act to consummate the Triumph merger.

When acting on applications under Section 3 of the BHC Act, the Federal Reserve Board is required by statute and under its regulations to consider a number of factors. These factors include, but are not limited to, the following: (i) the financial and managerial resources (including consideration of the competence, experience and integrity of the officers, directors and principal shareholders, as well as the pro forma capital ratios) and future prospects of the combined organization; (ii) the supervisory records of the parties and compliance with federal banking laws and regulations (specifically including the effectiveness of the applicant in combatting money laundering); (iii) the ways in which the transaction would satisfy the convenience and needs of the communities served by the parties; (iv) the effect of the transaction on the concentration of deposits on a nationwide basis; (v) the extent to which the transaction would result in greater or more concentrated risks to the stability of the U.S. banking or financial system; (vi) the effect of the transaction on competition or on the concentration of resources in any banking market; and (vii) the record of performance of each of Simmons Bank and Triumph Bank in meeting the credit needs of the respective communities that they serve, including low and moderate income neighborhoods within such communities, under the Community Reinvestment Act. As of their most recent Community Reinvestment Act examinations, Simmons Bank and Triumph Bank each had Community Reinvestment Act ratings of “satisfactory.”

The Landmark merger and the Triumph Bank merger are also subject to review and approval by the Federal Reserve Board under Section 18(c) of the Federal Deposit Insurance Act, or the Bank Merger Act. Specifically, Simmons Bank has submitted applications under the Bank Merger Act seeking the prior approval of the Federal Reserve Board for Landmark to merge with and into Simmons Bank, and for Triumph Bank to merge with and into Simmons Bank. With respect to an application filed under the Bank Merger Act, the Federal Reserve Board is required to consider, among other factors: (i) whether the effect of the applicable transaction in any portion of the country would substantially lessen competition, tend to create a monopoly, or otherwise retrain trade; (ii) the financial and managerial resources and future prospects of the banking organizations, including the effect of the applicable transaction on such resources (including capital and pro forma capital ratios of the combined organization and its management expertise, internal controls and risk management systems); (iii) the supervisory records of the banking organizations, including records of compliance with Bank Secrecy Act and anti-money laundering laws; (iv) the extent to which the applicable transaction would result in greater or more concentrated risks to the stability of the U.S. banking or financial system; and (v) the effect of the applicable transaction on the convenience and needs of the communities served by the banking organizations, including consideration of the records of performance of the relevant insured banking organizations under the Community Reinvestment Act. As of their most recent Community Reinvestment Act examinations, Simmons Bank, Landmark and Triumph Bank each had Community Reinvestment Act ratings of “satisfactory.”

A transaction approved under the Bank Merger Act or BHC Act generally may not be completed until 30 days after the approval of the appropriate federal banking agency is received (here, the Federal Reserve Board), during which time the Department of Justice, which we refer to as the DOJ, may initiate legal action to prevent consummation of the transaction if the DOJ determines the transaction may have a significantly adverse effect on competition. With the approval of the applicable federal agency and the concurrence of the DOJ, the 30-day waiting period may be reduced to no less than 15 days. The commencement of an antitrust action would stay the effectiveness of such an approval unless a court specifically ordered otherwise. In reviewing either

100

of the Landmark merger or the Triumph Bank merger, the DOJ could analyze the applicable merger’s effect on competition differently than the Federal Reserve Board, and thus it is possible that the DOJ could reach a different conclusion than the Federal Reserve Board regarding the transaction’s effects on competition. A determination by the DOJ not to object to either of these mergers may not prevent the filing of antitrust actions by private persons or state attorneys general.

Simmons is required to publish notice of its applications to the Federal Reserve Board and to provide the opportunity for public comment on these applications. The Federal Reserve Board takes into account the views of third-party commenters, particularly on the subject of the convenience and needs of the communities to be served. The Federal Reserve Board may upon request or upon its own initiative hold a public hearing or meeting to clarify facts or issues raised by the applications in order to aid in the Federal Reserve Board’s decision-making process. Any hearing, meeting or comments provided by third parties could prolong the period during which the applications are under review by the Federal Reserve Board.

State of Arkansas

Although no application is required to be filed with the ASBD in order to complete the Triumph merger, Simmons Bank is required to submit applications to, and receive approval from, the ASBD for the Landmark merger and Triumph Bank merger to complete such mergers. The ASBD will review the applications to determine whether the mergers comply with Arkansas law. Simmons Bank is required to publish notice of its applications to the ASBD and to provide the opportunity for public comment on these applications. The ASBD is required by law to hold a public hearing regarding each application. Any hearing, meeting or comments provided by third parties could prolong the period during which the applications are under review by the ASBD.

State of Tennessee

Although no application is required to be filed with the TDFI in order to complete the Landmark merger, the Triumph merger or the Triumph Bank merger, the TDFI requires that Simmons Bank notify the TDFI of the proposed mergers not later than the date on which the applications under the Bank Merger Act are filed with the Federal Reserve Board and provide to the TDFI a copy of the applications submitted to the Federal Reserve Board under the Bank Merger Act.

Additional Regulatory Approvals and Notices

Notifications and/or applications requesting approval may be submitted to various other federal and state regulatory authorities and self-regulatory organizations.

Simmons, Landmark and Triumph believe that the mergers do not raise significant regulatory concerns and that we will be able to obtain all requisite regulatory approvals. None of Simmons, Landmark or Triumph 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. In addition, there can be no assurance that such approvals will not impose conditions or requirements that, individually or in the aggregate, would or could reasonably be expected to have a material adverse effect on the financial condition, results of operations, assets or business of the combined company.

Simmons, Landmark and Triumph are not aware of any material governmental approvals or actions that are required for completion of the mergers 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.

THE MERGER AGREEMENTS

The following describes certain material provisions of the merger agreements, but does not describe all of the terms of the merger agreements and may not contain all of the information about the merger agreements that is important to you. The following is not intended to provide factual information about the parties or any of their respective subsidiaries or affiliates. The following description of the merger agreements is subject to, and qualified in its entirety by reference to, the Landmark merger agreement, which is attached to this proxy statement/prospectus as Annex A, and the Triumph merger agreement, which is attached to this proxy statement/prospectus as Annex B, each of which is incorporated by reference into this proxy statement/prospectus. We urge you to read each of the merger agreements carefully and in their entirety, as they are the legal document governing the respective mergers.

Structure of the Mergers

Each of the Simmons board of directors, the Simmons Bank board of directors and the Landmark board of directors, and each of the Simmons board of directors and the Triumph board of directors, adopted and approved the Landmark merger agreement and the Triumph merger agreement, respectively. The Landmark merger agreement provides for the merger of Landmark with and into Simmons Bank, with Simmons Bank as the surviving bank in the merger. The Triumph merger agreement provides for (a) the merger of Triumph with and into Simmons, with Simmons as the surviving corporation in the merger and (b) immediately following the Triumph merger, the merger of Triumph Bank with and into Simmons Bank, with Simmons Bank as the surviving bank.

The Merger Consideration

Landmark Consideration

Based on the assumptions set forth below, at the Landmark effective time, each share of Landmark common stock that is issued and outstanding immediately prior to the Landmark effective time (excluding certain specified shares of Landmark common stock held directly or indirectly by Landmark or Simmons and any dissenting shares) will be converted into the right to receive, subject to possible adjustment, the Landmark merger consideration, comprised of (i) approximately 0.2025 shares of Simmons common stock, with cash in lieu of fractional shares, and (ii) $0.29 in cash. In the aggregate, Simmons expects to issue approximately 4,500,000 shares of Simmons common stock and pay approximately $7,000,000 (minus the cash payment for outstanding Landmark stock options) to Landmark shareholders upon completion of the Landmark merger, subject to certain conditions and potential adjustments under the Landmark merger agreement. The Landmark merger consideration is based on the assumption that (i) 22,215,981 shares of Landmark common stock are issued and outstanding and (ii) 218,400 shares of Landmark common stock are subject to outstanding Landmark stock options with a weighted average exercise price of $3.49, in each case, immediately prior to the Landmark effective time. In addition, we have assumed that the Landmark/Simmons average closing price is equal to $27.49, which was the closing sales price of Simmons common stock on July 29, 2021, the last practicable trading day prior to printing this proxy statement/prospectus.

Triumph Consideration

Based on the assumptions set forth below, at the Triumph effective time, each share of Triumph common stock that is issued and outstanding immediately prior to the Triumph effective time (excluding certain specified shares of Triumph common stock held directly or indirectly by Triumph or Simmons and any dissenting shares) will be converted into the right to receive, subject to possible adjustment, the Triumph merger consideration, comprised of (i) approximately 0.9081 shares of Simmons common stock, with cash in lieu of fractional shares, and (ii) $ 0.36 in cash. In the aggregate, Simmons expects to issue approximately 4,164,839 shares of Simmons common stock and pay approximately $ 2,645,937.83 (minus the cash payment for outstanding Triumph stock options) to Triumph

102

shareholders upon completion of the Triumph merger, subject to certain conditions and potential adjustments under the Triumph merger agreement. See the section entitled “—Triumph Pricing Adjustments” below. The Triumph merger consideration is based on the assumption that (i) 4,586,300 shares of Triumph common stock are issued and outstanding and (ii) 148,763 shares of Triumph common stock are subject to outstanding Triumph stock options with a weighted average exercise price of $ 18.67 , in each case, immediately prior to the Triumph effective time. In addition, we have assumed that the Triumph/Simmons average closing price is equal to $ 27.49 , which was the closing sales price of Simmons common stock on July 29, 2021, the last practicable trading day prior to printing this proxy statement/prospectus.

Triumph Pricing Adjustments

Other than as described in this proxy statement/prospectus, there will be no adjustment to the Landmark merger consideration based upon changes in the market price of Simmons common stock or Landmark common stock prior to the time the Landmark merger is completed, and the Landmark merger agreement cannot be terminated due to a change in the price of Simmons common stock.

If, as of the Triumph determination date, (i) the Triumph/Simmons average closing price is greater than $37.28 and (ii) the difference between the percentage change in the Nasdaq Bank Index and the percentage change in the Triumph/Simmons average closing price exceeds 20%, then the Triumph stock consideration will be adjusted such that the total value of the aggregate Triumph merger consideration is not greater than $157,911,135.75.

In addition, if at any time during the five-day period commencing on the Triumph determination date, (i) the Triumph/Simmons average closing price is less than $24.85 and (ii) the difference between the percentage change in the Nasdaq Bank Index and the percentage change in the Triumph/Simmons average closing price exceeds 20%, then the Triumph board of directors may terminate the Triumph merger agreement; provided, that Simmons may prevent the Triumph merger agreement from being terminated by electing to increase the aggregate Triumph cash consideration such that the total value of the aggregate Triumph merger consideration is not less than $106,142,186.98. See “—Termination of the Merger Agreements” below.

Potential Adjustment to Exchange Ratios

Landmark Adjustments. If the number of shares of Simmons common stock outstanding changes as a result of a stock split, stock dividend, or similar recapitalization with respect to such stock prior to the Landmark effective time, then the Landmark merger consideration will be equitably and proportionately adjusted, if necessary and without duplication, to fully effect such change. If the aggregate Landmark cash consideration less the sum of all Landmark stock option payouts, which we refer to as the Landmark stock option payout, is less than $0, then the aggregate Landmark cash consideration will be increased such that difference between the aggregate Landmark cash consideration and the Landmark stock option payout equals $0 and the Landmark stock consideration will be decreased by an amount of shares of Simmons common stock equal to the quotient of such aggregate cash consideration increase divided by the Landmark/Simmons average closing price (for the avoidance of doubt, if the quotient includes a fractional share, then the quotient shall be rounded up to the next whole share).

Triumph Adjustments. If the number of shares of Simmons common stock outstanding changes as a result of a stock split, stock dividend, or similar recapitalization with respect to such stock prior to the effective times, then the Triumph merger consideration will be equitably and proportionately adjusted, if necessary and without duplication, to fully effect such change. If the aggregate Triumph cash consideration less the sum of all Triumph stock option payouts, which we refer to as the Triumph stock option payout, is less than $0, then the aggregate Triumph cash consideration will be increased such that the difference between the aggregate Triumph cash consideration and the Triumph stock option payout equals $0 and the Triumph stock consideration will be decreased by an amount of shares of Simmons common stock equal to the quotient of such aggregate cash consideration increase divided by the Triumph/Simmons

103

average closing price (for the avoidance of doubt, if the quotient includes a fractional share, then the quotient shall be rounded up to the next whole share). The forgoing adjustments, if any, will be applied after giving effect to the price adjustment, if any, as described in the section entitled “—Triumph Pricing Adjustments.”

Fractional Shares

Simmons will not issue any fractional shares of Simmons common stock in the mergers. Instead, Landmark shareholders and Triumph shareholders who otherwise would have been entitled to a fractional share of Simmons common stock will receive, in lieu thereof, an amount in cash, rounded up to the nearest whole cent (without interest), determined by multiplying the fraction of a share (rounded to the nearest thousandth when expressed in decimal form) of Simmons common stock to which such holder would otherwise be entitled by the Landmark/Simmons average closing price or the Triumph/Simmons average closing price, respectively.

Treatment of Equity Awards

Landmark Stock Options

At the Landmark effective time, each Landmark stock option, whether vested or unvested, outstanding immediately prior to the Landmark effective time, will be canceled and converted into the right to receive from Simmons a cash payment equal to the difference, if positive, between (1) the fully diluted per share value and (2) the exercise price of such Landmark stock option, which we refer to as the Landmark stock option payout. Any such Landmark stock option with an exercise price per share that equals or exceeds the amount set forth in (1) will be canceled with no consideration paid to the optionholder less any required withholding for taxes.

Triumph Stock Options

At the Triumph effective time, each Triumph stock option, whether vested or unvested, outstanding immediately prior to the Triumph effective time, will be canceled and converted into the right to receive from Simmons a cash payment equal to the difference, if positive, between (1) the fully diluted per share value and (2) the exercise price of such Triumph stock option, which we refer to as the Triumph stock option payout. Any such Triumph stock option with an exercise price per share that equals or exceeds the amount set forth in (1) will be canceled with no consideration paid to the optionholder less any required withholding for taxes.

Surviving Corporation Governing Documents; Directors and Officers

Landmark

At the Landmark effective time, the articles of agreement and incorporation and bylaws of Simmons Bank in effect immediately prior to the Landmark effective time will be the articles of agreement and incorporation and bylaws of Simmons Bank as the surviving bank, until the same be duly amended or repealed in accordance with its terms and applicable law. The directors and officers of Simmons Bank immediately prior to the Landmark effective time will serve as the directors and officers of Simmons Bank from and after the Landmark effective time in accordance with the bylaws of Simmons Bank.

Triumph

At the Triumph effective time, the Simmons charter and the Simmons bylaws in effect immediately prior to the Triumph effective time will be the charter and bylaws of Simmons as the surviving corporation, until the same be duly amended or repealed in accordance with their terms and applicable law. The directors and officers of Simmons immediately prior to the Triumph effective time will serve as the directors and officers of Simmons from and after the Triumph effective time in accordance with the Simmons bylaws.

104

Closing and Effective Time of the Mergers

Each merger will be completed only if all conditions to such merger discussed in this proxy statement/prospectus and set forth in the applicable merger agreement are either satisfied or waived (subject to applicable law). See the section entitled “—Conditions to Consummation of the Mergers” below.

The Landmark merger and the Triumph merger will become effective as of the date and time specified in the applicable articles of merger as duly filed with the Bank Commissioner of the State of Arkansas and the Secretary of State of the State of Arkansas, respectively, and each certificate of merger as duly filed with the Secretary of State of the State of Tennessee, which we refer to as the Landmark effective time or the Triumph effective time, as applicable.

In the merger agreements, Simmons has agreed to cause the Landmark effective time and the Triumph effective time, as applicable, to occur by the later of (i) October 8, 2021 or (ii) a date within 30 days following the satisfaction or waiver (subject to applicable law) of the last of the conditions specified in the applicable merger agreement to occur as determined by Simmons, or on another mutually agreed date. It currently is anticipated that the mergers will close in the fourth quarter of 2021, subject to the receipt of shareholder approvals, regulatory approvals and waivers and other customary closing conditions, but Simmons cannot guarantee when or if the mergers will be completed.

As described below, if either or both of the mergers is not completed by March 1, 2022, then, in the case of the Landmark merger, either Simmons, Simmons Bank or Landmark may choose to terminate the Landmark merger agreement, and in the case of the Triumph merger, either Simmons or Triumph may choose to terminate the Triumph merger agreement, at any time after such date if the failure of the applicable merger to occur on or before such date is not caused by any breach of the applicable merger agreement by the party electing to terminate such merger agreement.

Conversion of Shares; Exchange of Certificates

The conversion of Landmark common stock into the right to receive the Landmark merger consideration, and the conversion of Triumph common stock into the right to receive the Triumph merger consideration, will each occur automatically at the effective time of the applicable merger.

At or promptly after the effective time of each merger, Simmons will deposit with its transfer agent, or another exchange agent acceptable to Simmons, which we refer to as the exchange agent, (1) certificates or, at Simmons’ option, evidence of Simmons common stock in book-entry form equal to the stock consideration for the applicable merger and (2) funds equal to (i) the applicable cash consideration, (ii) the cash payable in lieu of fractional shares in connection with the applicable merger and (iii) after the Landmark effective time or the Triumph effective time, as applicable, and if applicable, any dividends or distributions which the Landmark shareholders or Triumph shareholders, respectively, have the right to receive under the applicable merger agreement.

As soon as reasonably practicable after the effective time of the respective mergers, the exchange agent will mail to holders of record of Landmark common stock and holders of record of Triumph common stock, as applicable, immediately prior to the applicable effective time, transmittal materials, which such shareholder may complete in accordance with the instructions thereto and deliver together with the proper surrender of a certificate to the exchange agent in exchange for the applicable merger consideration, any cash in lieu of fractional shares

105

of Simmons common stock, and any dividends or distributions such shareholder is entitled to receive under the applicable merger agreement.

Withholding

Simmons, the surviving corporation (in the case of the Triumph merger) or the surviving bank (in the case of the Landmark merger) or the exchange agent, as applicable, will be entitled to deduct and withhold from the applicable merger consideration, payouts in respect of Landmark stock options or Triumph stock options, as applicable, and any other amounts or property otherwise payable or distributable to any person pursuant to the applicable merger agreement to any person such amounts or property (or portions thereof) as it is required to deduct and withhold under the Code, and the rules and regulations promulgated thereunder, or any provision of applicable tax law. Any amounts so deducted, withheld or remitted will be treated for all purposes of the applicable merger agreement as having been paid to the person in respect of which such deduction and withholding was made.

Dividends and Distributions

Whenever a dividend or other distribution is declared by Simmons on Simmons common stock, with a record date after the effective time of each respective merger, the declaration will include dividends or other distributions on all whole shares of Simmons common stock issuable pursuant to each merger agreement, but such dividends or other distributions will not be paid to the holder thereof until such shareholder has duly surrendered its certificate in accordance with the applicable merger agreement. Following surrender of any such certificate (or affidavit or loss and other documentation required by the exchange agent or surviving bank (in the case of the Landmark merger) or surviving corporation (in the case of the Triumph merger) under the applicable merger agreement in lieu thereof), the record holder of the whole shares of Simmons common stock issued in exchange therefor will be paid, without interest, (1) all dividends and other distributions payable in respect of any such whole shares of Simmons common stock with a record date after the effective time of the applicable merger and a payment date on or prior to the date of such surrender and not previously paid and (2) at the appropriate payment date, the amount of dividends or other distributions with a record date after the effective time of the applicable merger but prior to such surrender and with a payment date subsequent to such surrender payable with respect to such shares of Simmons common stock.

Representations and Warranties

The representations, warranties and covenants described below and included in the merger agreements were made only for purposes of each merger agreement and as of specific dates, are solely for the benefit of Simmons and Landmark, in the case of the Landmark merger agreement, and Simmons and Triumph, in the case of the Triumph merger agreement, and may be subject to limitations, qualifications or exceptions agreed upon by the parties, including being qualified by confidential disclosures made for the purposes of, among other things, allocating contractual risk between the parties to each merger agreement rather than establishing matters as facts, and may be subject to standards of materiality that differ from those standards relevant to investors.

Many of the representations and warranties made by Landmark and Simmons, in the case of the Landmark merger agreement, and by Triumph, Simmons and Simmons Bank, in the case of the Triumph merger agreement, are qualified by a “materiality” or “material adverse effect” standard (that is, they will not be deemed to be untrue or incorrect unless their failure to be true or correct, individually or in the aggregate, would, as the case may be, be material to or have a material adverse effect on either Landmark or Simmons, as applicable, in the case of the Landmark merger agreement, or Triumph or Simmons, as applicable, in the case of the Triumph merger agreement).

Under the merger agreements, a material adverse effect is defined as, with respect to a party and its subsidiaries, any fact, circumstance, event, change, effect, development or occurrence that, individually or in the aggregate together with all other facts, circumstances, events, changes, effects, developments or occurrences, directly or indirectly, (a) prevents or materially impairs the ability of a party to timely consummate the transactions contemplated by the applicable merger agreement, or (b) has had or would reasonably be expected to result in a material adverse effect on the condition (financial or otherwise), results of operations, assets, liabilities or business of such party and its subsidiaries taken as a whole, but does not include effects to the extent resulting from the following (except, in certain instances, to the extent that 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):

| · | changes after the date of the applicable merger agreement in laws of general applicability to companies in the financial services industry;

110

The representations and warranties in the merger agreements do not survive the applicable effective time, and, as described below under “—Effect of Termination,” if the Landmark merger agreement or the Triumph merger agreement is validly terminated, the applicable merger agreement will become void and have no effect (except with respect to designated provisions of such merger agreement, including those related to payment of fees and expenses and the confidential treatment of information), unless a party breached such merger agreement.

Certain Additional Covenants

The merger agreements also contain additional covenants, including covenants relating to the filing of this proxy statement/prospectus, obtaining required consents, provision of certain reports, document archiving, consultation prior to issuing press releases or communications related to the mergers, potential shareholder litigation, cooperation for an efficient and orderly combination of Landmark and Simmons, in the case of the Landmark merger, and Triumph and Simmons, in the case of the Triumph merger, takeover laws, Landmark’s or Triumph’s, as applicable, delivery to Simmons of their closing financial statements, the listing of the shares of Simmons common stock to be issued in the mergers and public announcements with respect to the transactions contemplated by the merger agreements.

Regulatory Matters

Simmons and Landmark, in the case of the Landmark merger, and Simmons and Triumph, in the case of the Triumph merger, have agreed to file all reports required to be filed with regulatory authorities between the execution of the merger agreements and the effective time of the applicable merger, and to deliver to the other

115

party to the applicable merger agreement copies of all such reports promptly after the same are filed. If financial statements are contained in any such reports filed with the SEC or the Federal Reserve Board, such financial statements will fairly present the consolidated financial position of the entity filing such statements as of the dates indicated and the consolidated results of operations, changes in stockholders’ equity, and cash flows for the period then ended in accordance with GAAP (subject in the case of interim financial statements to normal recurring year-end adjustments that are not material) or applicable regulatory accounting principles consistently applied, except as may be otherwise indicated in the notes thereto and except for the omission of footnotes.

Simmons and Landmark, in the case of the Landmark merger, and Simmons and Triumph, in the case of the Triumph merger, have agreed to cooperate with each other and use their reasonable best efforts to prepare all documentation, to effect all applications, notices and filings, and to obtain all permits, consents, approvals and authorizations of all regulatory authorities and third parties that are necessary or advisable to consummate the transactions contemplated by the applicable merger agreement, including the mergers, and to comply with the terms and conditions of all such permits, consents, approvals and authorizations of all such third parties and regulatory authorities. Each of Simmons and Landmark, in the case of the Landmark merger, and Simmons and Triumph, in the case of the Triumph merger, have agreed to use its reasonable best efforts to resolve objections, if any, which may be asserted with respect to the applicable merger agreement or the transactions contemplated thereby under any applicable law or order.

Notwithstanding the foregoing, in no event is Simmons or any of its subsidiaries required, and Landmark and its subsidiaries, in the case of the Landmark merger, and Triumph and its subsidiaries, in the case of the Triumph merger, are not permitted (without Simmons’ prior written consent in its sole discretion), to take any action, or to commit to take any action, or to accept any restriction or condition, involving Simmons or its subsidiaries or Landmark or Triumph, as applicable, or its subsidiaries, which is materially burdensome on Simmons’ business or on the business of Landmark or Triumph or Triumph Bank, as applicable, or, in each case following the closing or which would likely reduce the economic benefits of the transactions contemplated by the applicable merger agreement to Simmons to such a degree that Simmons would not have entered into the applicable merger agreement had such condition or restriction been known to it at the date of the merger agreement, which condition or restriction we refer to as a burdensome condition.

For a more complete discussion of the regulatory approvals required to complete the mergers and the terms of the merger agreements related to regulatory approvals, see the section entitled “The Mergers—Regulatory Approvals Required for the Mergers and the Triumph Bank Merger.”

Tax Matters

Simmons and Landmark, in the case of the Landmark merger, and Simmons and Triumph, in the case of the Triumph merger, have agreed to use their respective reasonable best efforts to cause the applicable merger to qualify as a “reorganization” within the meaning of Section 368(a) of the Code, and to take no action that would cause such merger not to so qualify.

Employee Matters

The merger agreements provide that employees of Landmark or Triumph, as applicable, and its respective subsidiaries, while employed by Simmons following the effective time of the applicable merger, for a period of one year following such effective time, generally will be eligible to receive benefits that are, in the aggregate, substantially comparable to those provided to similarly situated Simmons employees. Additionally, such employees of Landmark, Triumph or its respective subsidiaries generally will receive service credit based on their service with Landmark or Triumph for purposes of determining eligibility to participate in Simmons’ benefit plans and for purposes of determining entitlement to paid time off under Simmons’ or Simmons Bank’s paid time off program, subject to certain specified exceptions.

116

D&O Indemnification and Insurance

The merger agreements provide that, subject to certain exceptions, for six years after the Landmark effective time and the Triumph effective time, as applicable, the surviving bank (in the case of the Landmark merger) or surviving corporation (in the case of the Triumph merger) will indemnify, defend and hold harmless each of the present and former directors and officers of Landmark and Triumph, as applicable, and each of its respective subsidiaries against all liabilities arising out of actions or omissions arising out of such person’s services in such capacities or, at Landmark’s or Triumph’s, as applicable, request, of another corporation, partnership, joint venture, trust or other enterprise, occurring at or prior to the effective time of the applicable merger, to the fullest extent permitted by the governing documents of Landmark or Triumph, as applicable, in effect on the date of the applicable merger agreement (including any provisions relating to the advancement of expenses incurred in the defense of any litigation).

The merger agreements also require the surviving bank (in the case of the Landmark merger) or surviving corporation (in the case of the Triumph merger) to use its reasonable best efforts to maintain for a period of six years after the effective time of the applicable merger Landmark’s and Triumph’s existing directors’ and officers’ liability insurance policy, or policies of at least the same coverage and amounts and containing terms and conditions which are substantially no less advantageous than the current policy (or, with the consent of Landmark or Triumph, as applicable, prior to the effective time of the applicable merger, any other policy), with respect to claims arising from facts or events that occurred prior to the effective time of such merger, and covering such individuals who are currently covered by such insurance, capped at 200% of the annual premium payments currently paid on Landmark’s or Triumph’s, as applicable, current policy. In lieu of the insurance described in the preceding sentence, prior to the effective time of the mergers, Simmons, or Landmark or Triumph, as applicable, in consultation with Simmons, may obtain a six-year “tail” prepaid policy providing coverage equivalent to such insurance.

Agreement Not to Solicit Other Offers

Landmark and Triumph have agreed to, promptly (but in no event more than 24 hours) following receipt of any acquisition proposal or any request for nonpublic information or any inquiry that could reasonably could be expected to lead to any acquisition proposal, advise Simmons in writing of the receipt of such acquisition proposal, request or inquiry, and the terms and conditions of such acquisition proposal, request or inquiry (including, in each case, the identity of the person making any such acquisition proposal, request or inquiry), and to promptly as practicable, provide to Simmons (a) a copy of such acquisition proposal, request or inquiry, if in writing, or (b) a written summary of the material terms of such acquisition proposal, request or inquiry, if oral. Landmark and Triumph have agreed to provide Simmons, as promptly as practicable (but in no event more than 24 hours), with notice setting forth all such information as is necessary to keep Simmons informed on a current basis of all developments, discussions, negotiations and communications regarding (including amendments or proposed amendments to) such acquisition proposal, request, or inquiry.

For purposes of the merger agreements,

| · | an “acquisition agreement” means a term sheet, letter of intent, commitment, memorandum of understanding, agreement in principle, merger agreement, acquisition agreement, option agreement or other similar agreement (whether written or oral, binding or nonbinding);

| · | an “acquisition proposal” means any offer, inquiry, proposal or indication of interest (whether communicated to Landmark or Triumph, as applicable, or publicly announced to Landmark shareholders or Triumph shareholders, respectively, and whether binding or non-binding) by any person (other than Simmons or its subsidiaries) for an acquisition transaction; and

Special Meetings and Recommendations of the Board of Directors of Landmark and Triumph

Landmark and Triumph have each agreed to hold a meeting of its respective shareholders as promptly as reasonably practicable after the registration statement of which this proxy statement/prospectus is a part is declared effective by the SEC for the purpose of obtaining shareholder approval of the Landmark merger and the Triumph merger, respectively. Landmark and Triumph have each agreed that its respective obligation to hold such meeting of its shareholders will not be affected by the commencement, proposal, disclosure or communication to Landmark or Triumph, respectively, of any acquisition proposal or change in recommendation, as described below.

Each of Landmark and Triumph through its respective board of directors has agreed to recommend to its respective shareholders the approval of the applicable merger proposal, to include such recommendation in this proxy statement/prospectus and to use their reasonable best efforts to obtain shareholder approval of the Landmark merger and the Triumph merger, respectively. Landmark and Triumph have each agreed that neither their respective board of directors nor any committee thereof shall (a) withhold, withdraw, qualify or modify such recommendation in any manner adverse to Simmons or Simmons Bank, (b) fail to make the such recommendation or otherwise submit the applicable merger proposal to their respective shareholders without such recommendation, (c) adopt, approve, agree to, accept, recommend or endorse an acquisition proposal, (d) fail to publicly and without qualification (i) recommend against any acquisition proposal or (ii) reaffirm the recommendation of the applicable merger proposal within ten business days (or such fewer number of days remaining prior to the applicable special meeting) after an acquisition proposal is made public or any request by Simmons to do so, (e) take any action or make any public statement, filing or release inconsistent with such recommendation, or (f) publicly propose to do any of the foregoing, which, collectively and individually, we refer to as a change in recommendation.

However, at any time prior to the applicable special meeting, the Landmark board of directors and Triumph board of directors may submit the respective merger agreement without recommendation, if Landmark or Triumph, as applicable, has received a superior proposal (as defined herein) (after giving effect to any revised offer from Simmons) and the Landmark board of directors or the Triumph board of directors, as applicable, has determined in good faith, after consultation with its financial advisors and outside legal counsel, that it would be a violation of the directors’ fiduciary duties under applicable law to make or continue to make the recommendation to approve the applicable merger proposal; provided, that the Landmark board of directors and Triumph board of directors, as applicable, may not take such actions unless:

| · | Landmark or Triumph, as applicable, has complied in all material respects with its respective non-solicit obligations described above;

| · | Landmark or Triumph, as applicable, gives Simmons at least five business days’ notice of its intention to take such action and a reasonable description of the events or circumstances giving rise to its determination to take such action;

| · | during such five business day period, Landmark or Triumph, as applicable, has, and has caused its respective financial advisors and outside legal counsel to, consider and negotiate with Simmons in good faith (to the extent Simmons desires to so negotiate) regarding any proposals, adjustments or modifications to the terms and conditions of the applicable merger agreement proposed by Simmons; and

| · | the Landmark board of directors or Triumph board of directors, as applicable, has determined in good faith, after consultation with its financial advisors and outside legal counsel and considering the results of such negotiations described above and giving effect to any proposals, amendments or modifications proposed by Simmons that such superior proposal remains a superior proposal and that it would nevertheless be a violation of the directors’ fiduciary duties under applicable law to make or continue to make the recommendation to approve the applicable merger proposal.

119

Any material amendment to any acquisition proposal will require a new determination and notice period.

For purposes of the merger agreements, a “superior proposal” means an unsolicited bona fide written acquisition proposal with respect to which the Landmark board of directors or Triumph board of directors, as applicable, determines in its good faith judgment (based on, among other things, the advice of outside legal counsel and a financial advisor) is reasonably likely to be consummated in accordance with its terms, and if consummated, would result in a transaction more favorable, from a financial point of view, to Landmark shareholders or Triumph shareholders, respectively, than the applicable merger and the other transactions contemplated by the applicable merger agreement (as it may be proposed to be amended by Simmons), taking into account all relevant factors (including the acquisition proposal and the applicable merger agreement (including any proposed changes to the applicable merger agreement that may be proposed by Simmons in response to such acquisition proposal)); provided, that for purposes of the definition of superior proposal, the references to “20%” in the definition of acquisition transaction will be deemed to be references to “50%.”

As of the date of this proxy statement/prospectus, none of Simmons, Landmark or Triumph has reason to believe that any of these conditions will not be satisfied.

Termination of the Merger Agreements

| o | any law or order permanently restraining, enjoining or otherwise prohibiting the consummation of the transactions contemplated by the applicable merger agreement becomes final and nonappealable, so long as the party seeking to terminate the applicable merger agreement has used its reasonable best efforts to contest, appeal and change or remove such denial, law or order;

| o | the applicable merger has not been consummated by March 1, 2022, which we refer to as the outside date, if the failure to consummate the transactions contemplated by the applicable merger agreement on or before such date is not caused by the terminating party’s breach of the applicable merger agreement, which we refer to as an outside date termination; or

| o | if there was a breach of any of the covenants or agreements or any of the representations or warranties (or any such representation or warranty ceases to be true) set forth in the applicable merger agreement on the part of Landmark or Triumph, as applicable, in the case of a termination by Simmons or Simmons Bank, as applicable, or Simmons or Simmons Bank, as applicable, in the case of a termination by Landmark or Triumph, as applicable, which breach or failure to be true, either individually or in the aggregate with all other breaches by such party (or failures of such representations or warranties to be true), would constitute, if occurring or continuing on the closing date, the failure of a Simmons, Simmons Bank, as applicable, or Landmark or Triumph, as applicable, condition to closing, respectively, and is not cured within 45 days following written notice or by its nature or timing cannot be cured during such period (or such fewer days as remain prior to the outside date); provided, that the terminating party is not then in material breach of any representation, warranty, covenant or other agreement contained in the applicable merger agreement, which we refer to as a breach termination.

Effect of Termination

Termination Fees

Landmark and Triumph, as applicable, will pay Simmons a termination fee of $7,000,000 and $6,500,000, respectively, if:

| · | Simmons or Simmons Bank, as applicable, effects a board breach termination.

If Landmark or Triumph, as applicable, fails to pay such termination fee when due, then such party must pay to Simmons its costs and expenses (including attorneys’ fees) in connection with collecting such fee, together with interest on the amount of such fee at the prime rate of Citibank, N.A. from the date such payment was due under the applicable merger agreement until the date of payment.

123

Each of the directors of Landmark and certain executive officers of Landmark, as well as each of the directors of Triumph and certain executive officers of Triumph, in each case in their capacities as individuals, have separately entered into a Landmark voting agreement or Triumph voting agreement, respectively, in which they have agreed to vote (or cause to be voted), in person or by proxy, or deliver (or cause to be delivered) a written consent covering, all covered shares as to which they control the right to vote, (1) in favor of the adoption and approval of the applicable merger agreement and the consummation of the transactions contemplated thereby, including the applicable merger, (2) against any action or agreement that could result in a breach of any covenant, representation or warranty or any other obligation of Landmark or Triumph, respectively, under such merger agreement, (3) against any acquisition proposal and (4) against any action, agreement, amendment to any agreement or organizational document, transaction, matter or proposal submitted for vote or written consent of Landmark shareholders or Triumph shareholders, respectively, that is intended or would reasonably be expected to impede, interfere with, prevent, delay, postpone, discourage, disable, frustrate the purposes of or adversely affect such merger or the other transactions contemplated by such merger agreement or the respective voting agreement or the performance by Landmark or Triumph, respectively, of its obligations under the applicable merger agreement or by the such person of his or her obligations under the applicable voting agreement. In addition, the Landmark voting agreements and Triumph voting agreements provide that such shareholders will not sell or transfer any of their shares of Landmark common stock or Triumph common stock, respectively, of which they are a record owner, subject to certain exceptions, until the earlier of the receipt of the Landmark shareholder approval or Triumph shareholder approval, respectively, or the date on which the applicable merger agreement is terminated in accordance with its terms.

Subject to certain exceptions, the Landmark voting agreements and Triumph voting agreements also provide that, for a period of two years following the effective time of the applicable merger, directly or indirectly, either for him or herself or for any other person other than for Simmons or Simmons’ affiliates, such shareholder will not within 50 miles of any branch or other office of Landmark or Triumph or Triumph Bank, as applicable, as of the date of the Landmark voting agreement or Triumph voting agreement, as applicable, participate in any

124

business that engages in the business of acting as a commercial, community or retail banking business; provided, that if, as of the date of the Landmark voting agreement or Triumph voting agreement, as applicable, and at all times during such two-year period, such shareholder holds not more than a 5% direct or indirect equity interest in such person, then such shareholder may retain (but not increase) such ownership interest without being deemed to “participate” in the business conducted by such person.

The Landmark voting agreements and Triumph voting agreements will remain in effect until the earlier to occur of the closing of the respective merger and the date of termination of the applicable merger agreement in accordance with its terms; provided, that if such closing occurs, the non-competition provisions described immediately above survive until the second anniversary of such closing date.

As of the Landmark record date and Triumph record date, shares constituting approximately 21.54% of the Landmark common stock entitled to vote at the Landmark special meeting and approximately 44.49% of the Triumph common stock entitled to vote at the Triumph special meeting are subject to Landmark voting agreements or Triumph voting agreements, respectively.

The foregoing description of the Landmark voting agreements and the Triumph voting agreements is subject to, and qualified in its entirety by reference to, the Landmark voting agreements and Triumph voting agreements, respectively, forms of which are attached to this proxy statement/prospectus as Annex C and Annex D, respectively, and are incorporated by reference into this proxy statement/prospectus.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF THE MERGERS

The following is a general discussion of the material U.S. federal income tax consequences relating to the mergers to a U.S. holder (as defined below) that receives Simmons common stock or cash pursuant to either the Landmark merger or the Triumph merger.

For purposes of this discussion, a “U.S. holder” means any beneficial owner of Landmark common stock or Triumph common stock that is, for U.S. federal income tax purposes, (1) an individual citizen or resident of the United States, (2) a corporation (or entity treated as a corporation for U.S. federal income tax purposes) organized in or under the laws of the United States or any state thereof or the District of Columbia, (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 made a valid election to be treated as a U.S. person for U.S. federal income tax purposes, or (4) an estate, the income of which is subject to U.S. federal income tax regardless of its source.

This discussion applies only to a U.S. holder who holds its shares of Landmark common stock or Triumph common stock as a capital asset within the meaning of Section 1221 of the Code and exchanges those shares for the applicable merger consideration in the applicable merger. Further, this discussion is for general information only and does not purport to address all aspects of U.S. federal income taxation that might be relevant to a U.S. holder in light of its particular circumstances and does not apply to a U.S. holder subject to special treatment under the U.S. federal income tax laws (such as, for example, a dealer or broker in securities, commodities or foreign currencies, a trader in securities that elects to apply a mark-to-market method of accounting, a bank or a financial institution of certain other kinds, an insurance company, a regulated investment company or a real estate investment trust, a tax-exempt organization, a holder subject to the alternative minimum tax provisions of the Code, an S corporation, a holder whose functional currency is not the U.S. dollar, a holder who holds shares of Landmark common stock or Triumph common stock as part of a hedge, straddle, constructive sale or conversion transaction or other integrated investment, a holder who exercises appraisal rights, or a holder required to accelerate the recognition of any item of gross income for U.S. federal income tax purposes with respect to Landmark common stock or Triumph common stock as a result of such item being taken into account in an applicable financial statement).

This discussion does not address any U.S. federal tax consequences other than U.S. federal income tax consequences (including any U.S. federal estate, gift, Medicare or alternative minimum taxes) or any U.S. state or local, or non-U.S. tax consequences.

If a partnership (including for this purpose an entity treated as a partnership for U.S. federal income tax purposes) holds Landmark common stock or Triumph common stock, the tax treatment of a partner in such partnership generally will depend on the status of the partner and the activities of the partnership. Any entity treated as a partnership for U.S. federal income tax purposes that holds Landmark common stock or Triumph common stock, and any partners in such partnership, are strongly urged to consult their tax advisors about the tax consequences of the merger transactions to them.

The opinions described below will not be binding on the IRS, or any court. Simmons, Landmark and Triumph have not sought and will not seek any ruling from the IRS regarding any matters relating to the mergers, and as a result, there can be no assurance that the IRS will not assert, or that a court would not sustain, a position contrary to any of the conclusions set forth below. In addition, if any of the representations or assumptions upon which the Landmark opinion (as defined below) are based is inconsistent with the actual facts, the U.S. federal income tax consequences of the Landmark merger could be adversely affected, as could the U.S. federal income tax consequences of the Triumph merger if any of the representations or assumptions on which the Triumph opinion (as defined below) is based are inconsistent with the facts.

126

This discussion, and the tax opinions referred to below, is based upon the Code, the U.S. Treasury regulations promulgated thereunder and judicial and administrative authorities, rulings, and decisions, all as in effect on the date of this proxy statement/prospectus. 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.

Determining the actual tax consequences of the Landmark merger or the Triumph merger to you may be complex and will depend on your specific situation and on factors that are not within our control. You are strongly urged to consult with your tax advisor as to the specific tax consequences of the Landmark merger or the Triumph merger in your particular circumstances, including the applicability and effect of the alternative minimum tax and any U.S. federal, state and local, foreign and other tax laws and of changes in those laws.

General

The respective obligations of Simmons and Landmark to complete the Landmark merger are contingent upon Simmons and Landmark receiving a legal opinion from Covington, which we refer to above as the Landmark opinion, that the Landmark merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code. Similarly, the respective obligations of Simmons and Triumph to complete the Triumph merger are conditioned upon Simmons and Triumph receiving a legal opinion from Covington, which we refer to above as the Triumph opinion, to the effect that the Triumph merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code. None of Simmons, Landmark or Triumph currently intends to waive this condition to the consummation of the Landmark merger or the Triumph merger, as applicable. If any party waives this condition after this registration statement is declared effective by the SEC, and if the tax consequences of the Landmark merger to Landmark shareholders or of the Triumph merger to Triumph shareholders have materially changed, Simmons and Landmark or Triumph, as applicable, will recirculate appropriate soliciting materials to resolicit the votes of Landmark shareholders or Triumph shareholders.

The opinions of Covington will be based on customary assumptions and representations from Simmons, Landmark, and Triumph, as well as certain covenants and undertakings by Simmons, Landmark, and Triumph. In the case of the Landmark merger, these assumptions and representations include the factual assumption that the total market value, as of the effective time, of Simmons common stock issued to Landmark shareholders will be no less than 40 percent of the sum of (a) the amount of cash paid to Landmark shareholders exercising dissenters’ rights, (b) the amount of the cash consideration paid to Landmark shareholders who do not exercise dissenters’ rights, and (c) the total market value, as of the Landmark effective time, of Simmons common stock issued to Landmark shareholders. In the case of the Triumph merger, these assumptions and representations include the factual assumption that the total market value, as of the effective time, of Simmons common stock issued to Triumph shareholders will be no less than 40 percent of the sum of (a) the amount of cash paid to Triumph shareholders exercising dissenters’ rights, (b) the amount of the cash consideration paid to Triumph shareholders who do not exercise dissenters’ rights, and (c) the total market value, as of the effective time, of Simmons common stock issued to Triumph shareholders. If any of the assumptions, representations, covenants, or undertakings is incorrect, incomplete, inaccurate, or is violated, the validity of the opinions described above may be affected and the U.S. federal income tax consequences of the mergers could differ materially from those described in this proxy statement/prospectus.

The following discussion assumes that the each of the Landmark merger and the Triumph merger qualifies as a “reorganization” within the meaning of Section 368(a) of the Code.

U.S. Federal Income Tax Consequences of the Merger to U.S. Holders

A U.S. holder of Landmark common stock or Triumph common stock receiving a combination of Simmons common stock and cash in exchange for such Landmark common stock or Triumph common stock will (1) not recognize any loss upon surrendering its Landmark common stock or Triumph common stock and (2) recognize

127

gain upon surrendering its Landmark common stock or Triumph common stock equal to the excess, if any, of (a) the sum of any cash consideration received plus the fair market value (determined as of the effective time of the applicable merger) of the Simmons common stock received over (b) such U.S. holder’s aggregate tax basis in the shares of Landmark common stock or Triumph common stock surrendered, but only to the extent of the amount of any cash consideration received.

Cash Instead of Fractional Shares

If a U.S. holder receives cash instead of a fractional share of Simmons common stock, the U.S. holder will be treated as having received such fractional share of Simmons common stock pursuant to the applicable merger and then as having received cash in exchange for such fractional share of Simmons common stock. As a result, such a U.S. holder generally will recognize gain or loss equal to the difference between the amount of cash received instead of a fractional share and the U.S. holder’s basis in the fractional share of Simmons common stock as set forth above. Such gain or loss generally will be capital gain or loss and will be long-term capital gain or loss if, as of the effective time of the applicable merger, the U.S. holder’s holding period for such fractional share (including the holding period of shares of Landmark common stock or Triumph common stock surrendered therefor) exceeds one year.

Information Reporting and Backup Withholding

A non-corporate U.S. holder of Landmark common stock or Triumph common stock may be subject, under certain circumstances, to information reporting and backup withholding (currently at a rate of 24 percent) on any cash payments that it receives. Such a U.S. holder generally will not be subject to backup withholding, however, if it:

| · | furnishes a correct taxpayer identification number, certifies that it is not subject to backup withholding 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 will generally be allowed as a refund or credit against U.S. federal income tax liability, provided that the required information is timely furnished to the IRS.

Certain Reporting Requirements

If a U.S. holder receives Simmons common stock pursuant to the mergers and is considered a “significant holder,” it will be required (1) to file a statement with its U.S. federal income tax return providing certain facts pertinent to the applicable merger, including its tax basis in, and the fair market value of, the Landmark common stock or Triumph common stock that it surrendered, and (2) to retain permanent records of these facts relating to the merger. A holder of Landmark common stock or Triumph common stock is considered a “significant holder” if, immediately before the applicable merger, such holder (a) owned at least 1% (by vote or value) of the outstanding stock of Landmark or Triumph, respectively, or (b) owned Landmark or Triumph securities, respectively, with a tax basis of $1.0 million or more.

This discussion of certain material U.S. federal income tax consequences is for general information purposes only and is not intended to be, and may not be construed as, tax advice. Holders of Landmark common stock or Triumph common stock are urged to consult their tax advisors with respect to the application of U.S. federal income tax laws to their particular situations as well as any tax consequences arising under the U.S. federal estate or gift tax rules, or under the laws of any state, local, foreign or other taxing jurisdiction or under any applicable tax treaty.

COMPARISON OF SHAREHOLDERS’ RIGHTS OF SIMMONS AND LANDMARK

If the Landmark merger is completed, Landmark shareholders will have a right to receive shares of Simmons common stock for their shares of Landmark common stock. Landmark is organized under the laws of Tennessee, and Simmons is organized under the laws of Arkansas. Simmons and Landmark believe that the following summary describes the material differences between (1) the rights of Landmark shareholders as of the date of this proxy statement/prospectus under the TBCA, the Landmark charter and the Landmark bylaws, and (2) the rights of holders of Simmons common stock as of the date of this proxy statement/prospectus under the ACA, the Simmons charter and the Simmons bylaws.

Charter Amendment: |  | Under Section 48-20-102 of the TBCA, unless the charter provides otherwise, the board of directors may amend the charter without shareholder action to delete the names and addresses of the initial directors, delete the name and address of the initial registered agent or registered office, if a statement of change is on file with the secretary of state, designate or change the address of the principal office of the corporation, change each issued and unissued authorized share of an outstanding class into a greater number of whole shares if the corporation has only shares of that class outstanding, change the corporate name by substituting the word “corporation,” “incorporated,” “company,” or the abbreviation “corp.,” “inc.,” or “co.,” for a similar word or abbreviation in the name, or by adding, deleting or changing a geographical attribution for the name, designate the street address and zip code of the corporation’s current registered office and the name of its current registered agent at that office, delete the initial principal office, or make any other change expressly permitted therein. Pursuant to Section 48-20-103 of the TBCA, any other amendment to the charter must first be recommended to the shareholders by the board of directors and thereafter be approved by a majority of the votes entitled to be cast on the amendment by any voting group with respect to which the amendment would create dissenters’ rights, unless the charter or the board of directors require a greater vote. |  | The Simmons charter provides that it may be amended by the approval of 80% of the shares entitled to vote on such amendment, unless such amendment has been approved by an affirmative vote of 80% of the Simmons board of directors, or if an interested shareholder is the proponent of such charter amendment, then 80% of the incumbent directors on the date preceding the date when the proponent became an interested shareholder. If the proposed amendment receives the approval of 80% of the Simmons board of directors or the incumbent directors, as the case may be, the amendment must be approved by a majority of the votes entitled to be cast on the amendment at a meeting where a quorum of the Simmons shareholders exists. Under Section 4-27-1002 of the ACA, the board of directors may amend the charter of a corporation without shareholder approval to extend its duration, change the name of the corporation to include words required by the ACA, declare a forward stock split in a class of shares if there is only one class outstanding, and for certain other ministerial actions.

Notwithstanding the foregoing, pursuant to Section 4-27-1004 of the ACA, if an amendment would adversely affect a particular class of stock, such amendment would require the approval of a majority of the votes of that class, voting as a separate voting group, that are entitled to be cast on the amendment at a shareholders’ meeting where a quorum exists.

Amendment of Bylaws: |  | The Landmark bylaws provide that any provision of the bylaws may be amended, altered or repealed by the Landmark board of directors except for those provisions relating to the duties, term of office or indemnification of a director, and that any provision may be altered, amended or repealed by the shareholders. The Landmark bylaws provide that all matters to be decided by the Landmark shareholders shall be decided by the vote of a majority in voting interest of the shareholders present in person or by proxy and entitled to vote there at and thereon. Section 48-20-201 of the TBCA states that a corporation’s board of directors may amend or repeal the corporation’s bylaws unless the charter or the TBCA reserves this power to the shareholders in whole or in part. A corporation’s shareholders may amend or repeal the corporation’s bylaws even though the bylaws may also be amended by the board of directors. |  | The Simmons bylaws provide that they may be amended, altered, or repealed, at any meeting of the Simmons board of directors, by a majority vote. Section 4-27-1020 of the ACA provides that a corporation’s board of directors may amend or repeal the corporation’s bylaws unless otherwise stated in the corporation’s charter or the amendment deals with a particular provision that is reserved for shareholders’ approval. A corporation’s shareholders may amend or repeal the corporation’s bylaws even though the bylaws may also be amended by the board of directors.

|  | In connection with an action by or in the right of the corporation, Tennessee law provides indemnification similar to that set forth in the immediately preceding paragraph; except that for indemnification to be proper in any criminal proceeding, the individual must have had no reasonable cause to believe that his or her conduct was unlawful. Section 48-18-508 of the TBCA permits a corporation to purchase and maintain insurance on behalf of a director, officer, employee or agent of the corporation against liability asserted against or incurred by the individual in that capacity or arising from such status. |  | Under the Simmons charter and Simmons bylaws, the Simmons board of directors may cause Simmons to purchase and maintain insurance on behalf of any director or officer of Simmons against any liability, whether or not Simmons would have the power to indemnify such person. Section 4-27-850 of the ACA provides that a corporation may indemnify any person who was made a party to a proceeding for the reason he or she is a director, officer or employee of the corporation against expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred in connection with the proceeding, if he or she acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. The corporation must indemnify a director, officer, or employee who has been successful on the merits at a proceeding that he or she was a party because he or she is a director, officer, or employee of the corporation. No indemnification may be made if the person will have been adjudged liable to the corporation unless otherwise specified by the court. The Simmons charter provides, to the fullest extent permitted by the ACA, that a director will not be liable to Simmons or its shareholders for monetary damages for a breach of fiduciary duty as a director. Section 4-27-830 of the ACA provides that if a director complies with the standard of conduct under the ACA, the director may not be liable for any action taken as a director, or failure to take such action.

Shareholders’ Rights of Dissent and Appraisal: |  | Sections 48-23-201–209 of the TBCA provide that any shareholder will be deemed a dissenting shareholder and entitled to appraisal if such shareholder: (1) owns stock of a corporation as of the record date of the meeting of shareholders at which the plan of merger is submitted to a vote, (2) files a written objection to the plan of merger before the vote is taken, and (3) does not vote in favor of the merger proposal. The surviving corporation must pay to each dissenting shareholder the fair value of his or her shares following a demand for payment and deposit of his or her shares. |  | Under Section 4-27-1302 of the ACA, a shareholder is entitled to dissent from and obtain payment of the fair value of the shareholder’s shares in the event of certain extraordinary corporate actions such as a plan of conversion, merger, share exchange, sale of substantially all of the assets, or certain amendments to the charter. Sections 4-27-1320 through 4-27-1331 of the ACA provide the process of obtaining payment which consists of the shareholder delivering notice of intent to demand payment, shareholder must not vote his or her shares in favor of the proposed action, certify whether he or she acquired ownership of the shares prior to the corporate action, deposit his or her certificates if shareholder rejects the corporation’s offer, and judicial appraisal of the value of the shares if shareholder rejects the corporation’s offer. The ACA also places certain obligations on the corporation such as providing dissenters’ notice to all shareholders. A shareholder entitled to dissent and obtain payment for the shareholder’s shares may not challenge the corporate action creating the shareholder’s entitlement unless such action is unlawful or fraudulent with respect to the shareholder or the corporation.
Control Share Acquisition: |  | The Landmark charter does not address the application of Sections 48-103-301–312 of the TBCA to Landmark shares. |  | No “control share acquisition,” “business combination moratorium,” “fair price” or other form of anti-takeover statute or regulation is applicable to Simmons under Arkansas law.

Expenses incurred by a director or officer of Simmons in defending a civil or criminal action, suit or proceeding by reason of the fact that person is, or was, a director or officer of Simmons, must be paid by Simmons in advance of the final disposition of such action suit or proceeding upon authorization by the Simmons board of directors by a majority vote of a quorum consisting of directors who are not parties to the action, suit or proceeding and if such a quorum is unobtainable, if a quorum of disinterested directors so directs, then by independent legal counsel in a written opinion or by the Simmons shareholders.

|  | Triumph |  | Simmons
|  | The Triumph bylaws further provide that indemnification will be paid unless a determination is made (a) by a majority of the members of the Triumph board of directors who were not parties to such action, suit or proceeding even if less than a quorum, or (b) if such a majority of the disinterested members of the Triumph board of directors so direct, by independent legal counsel in a written opinion, or (c) by the Triumph shareholders, that such indemnification is not proper in the circumstances because the individual has not met the applicable standard of conduct set forth in the Triumph bylaws. The Triumph bylaws also provide that Triumph may purchase and maintain insurance on behalf of any person who is a director, officer, employee or agent of Triumph, or who is serving at the request of Triumph in such a position for another corporation, partnership, joint venture, trust or other enterprise, against any liability asserted against, and incurred by, him or on his behalf arising out of this status. The Triumph bylaws provide that costs, charges and expenses incurred by a person referred to in defending any civil, criminal, administrative or investigative action, suit or proceeding must be paid by Triumph in advance of the final disposition of such action, suit or proceeding; provided, however, that the payment of such costs may be made only upon receipt of an undertaking by or on behalf of the individual to repay all amounts so advanced in the event that it is ultimately determined that such person is not entitled to be indemnified by Triumph. The majority of the Triumph board of directors may, upon the approval of such person, authorize Triumph’s counsel to represent such person, in any action, suit or proceeding. |  | Under the Simmons charter and Simmons bylaws, the Simmons board of directors may cause Simmons to purchase and maintain insurance on behalf of any director or officer of Simmons against any liability, whether or not Simmons would have the power to indemnify such person. Section 4-27-850 of the ACA provides that a corporation may indemnify any person who was made a party to a proceeding for the reason he or she is a director, officer or employee of the corporation against expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred in connection with the proceeding, if he or she acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. The corporation must indemnify a director, officer, or employee who has been successful on the merits at a proceeding that he or she was a party because he or she is a director, officer, or employee of the corporation. No indemnification may be made if the person will have been adjudged liable to the corporation unless otherwise specified by the court. The Simmons charter provides, to the fullest extent permitted by the ACA, that a director will not be liable to Simmons or its shareholders for monetary damages for a breach of fiduciary duty as a director. Section 4-27-830 of the ACA provides that if a director complies with the standard of conduct under the ACA, the director may not be liable for any action taken as a director, or failure to take such action.

|  | Triumph |  | Simmons
Shareholders’ Rights of Dissent and Appraisal: |  | Sections 48-23-201–209 of the TBCA provide that any shareholder will be deemed a dissenting shareholder and entitled to appraisal if such shareholder: (1) owns stock of a corporation as of the record date of the meeting of shareholders at which the plan of merger is submitted to a vote, (2) files a written objection to the plan of merger before the vote is taken, and (3) does not vote in favor of the merger proposal. The surviving corporation must pay to each dissenting shareholder the fair value of his or her shares following a demand for payment and deposit of his or her shares. |  | Under Section 4-27-1302 of the ACA, a shareholder is entitled to dissent from and obtain payment of the fair value of the shareholder’s shares in the event of certain extraordinary corporate actions such as a plan of conversion, merger, share exchange, sale of substantially all of the assets, or certain amendments to the charter. Sections 4-27-1320 through 4-27-1331 of the ACA provide the process of obtaining payment which consists of the shareholder delivering notice of intent to demand payment, shareholder must not vote his or her shares in favor of the proposed action, certify whether he or she acquired ownership of the shares prior to the corporate action, deposit his or her certificates if shareholder rejects the corporation’s offer, and judicial appraisal of the value of the shares if shareholder rejects the corporation’s offer. The ACA also places certain obligations on the corporation such as providing dissenters’ notice to all shareholders. A shareholder entitled to dissent and obtain payment for the shareholder’s shares may not challenge the corporate action creating the shareholder’s entitlement unless such action is unlawful or fraudulent with respect to the shareholder or the corporation.
Control Share Acquisition: |  | The Triumph charter does not address the application of Sections 48-103-301–312 of the TBCA to Triumph shares. |  | No “control share acquisition,” “business combination moratorium,” “fair price” or other form of anti-takeover statute or regulation is applicable to Simmons under Arkansas law.

LEGAL MATTERS

The validity of the Simmons common stock to be issued in connection with the mergers will be passed upon for Simmons by Friday, Eldredge & Clark, LLP, Little Rock, Arkansas. Certain tax matters relating to the mergers will be passed upon by Covington & Burling LLP.

EXPERTS

The audited annual consolidated financial statements of Simmons appearing in Simmons’ Annual Report on Form 10-K for the year ended December 31, 2020 and the effectiveness of Simmons’ internal control over financial reporting as of such date have been audited by BKD, LLP, an independent registered public accounting firm, as set forth in its reports included therein, which are incorporated herein by reference. Such consolidated financial statements are incorporated herein by reference in reliance upon such reports given on the authority of such firm as experts in auditing and accounting.

With respect to the unaudited interim consolidated financial information of Simmons appearing in its Quarterly Report on Form 10-Q for the period ended March 31, 2021 that is incorporated herein by reference, BKD, LLP, Simmons’ independent registered public accounting firm, has applied limited procedures in accordance with professional standards for review of such information. However, as stated in its separate report included therein, BKD, LLP did not audit and it does not express an opinion on that interim financial information. Because of the limited nature of the review procedures applied, the degree of reliance on its reports on such information should be restricted. Pursuant to Rule 436(c) under the Securities Act, this report on Simmons’ unaudited interim consolidated financial information should not be considered a part of the registration statement prepared or certified by its independent registered public accounting firm within the meaning of Sections 7 and 11 of the Securities Act.

OTHER MATTERS

No matters other than the matters described in this proxy statement/prospectus are anticipated to be presented for action at the Landmark special meeting or the Triumph special meeting or at any adjournment or postponement of the Landmark special meeting or the Triumph special meeting.

SIMMONS ANNUAL MEETING SHAREHOLDER PROPOSALS

Simmons shareholders who intend to submit proposals pursuant to Rule 14a-8 of the Exchange Act to be presented at Simmons’ 2022 Annual Meeting of Shareholders and included in Simmons’ proxy statement relating to such meeting must have submitted such proposals to the Corporate Secretary of Simmons at Simmons’ principal executive offices no later than December 16, 2021. Such proposals must also comply with the additional requirements of Rule 14a-8 of the Exchange Act (or any successor rule) to be eligible for inclusion in the proxy statement for Simmons’ 2022 Annual Meeting of Shareholders.

In addition, the Simmons bylaws provide that only such business (including, without limitation, the nomination of persons for election to the Simmons board of directors) which is properly brought before a Simmons shareholder meeting will be conducted. For business (including, without limitation, the nomination of persons for election to the Simons board of directors) to be properly brought before an annual meeting of Simmons shareholders by a Simmons shareholder, the shareholder must provide notice to the Corporate Secretary of Simmons at Simmons’ principal executive offices not later than 90 days nor earlier than 120 days prior to the first anniversary of the prior year’s annual meeting of Simmons shareholders. In the event that Simmons did not hold an annual meeting of the shareholders in the prior year or if the first anniversary of the prior year’s annual

158

meeting of Simmons shareholders is more than 30 days before or after the date of the current year’s annual meeting of Simmons shareholders, the shareholder’s notice is timely only if it is delivered to the Corporate Secretary of Simmons at the principal executive offices of Simmons no later than the 10th day after Simmons publicly announces the date of the current year’s annual meeting of Simmons shareholders or the 90th day before the date of the current year’s annual meeting of Simmons shareholders, whichever is later. To be in proper written form, a shareholder’s notice to Simmons’ Corporate Secretary must comply with all requirements contained in the Simmons bylaws, a copy of which may be obtained upon written request to the Corporate Secretary of Simmons.

Accordingly, a Simmons shareholder who intended to raise a proposal to be acted upon at Simmons’ 2022 Annual Meeting of Shareholders, but who did not desire to include the same in Simmons’ 2022 proxy statement, must have provided written notice to Simmons’ Corporate Secretary no earlier than January 20, 2022 nor later than February 19, 2022. The persons named as proxies in Simmons’ proxy for Simmons’ 2022 Annual Meeting of Shareholders may exercise their discretionary authority to act upon any proposal which is properly brought before a shareholder meeting, and Simmons reserves the right to reject, rule out of order or take other appropriate action with respect to any proposal that does not comply with these and other applicable requirements.

The respective boards of directors of Landmark, Simmons and Simmons Bank have approved and adopted this Agreement and determined that this Agreement and the transactions contemplated hereby are advisable and in the best interests of their respective companies and their respective shareholders. Under the terms and subject to the conditions of this Agreement and in accordance with applicable provisions of the Arkansas Banking Code of 1997, as amended (the “ABC”), and the Tennessee Banking Act (the “TBA”), Landmark will merge with and into Simmons Bank (the “Merger”), with Simmons Bank as the surviving bank in the Merger (sometimes referred to in such capacity as the “Surviving Bank”).

As a condition and an inducement for Simmons and Simmons Bank to enter into this Agreement, each of the directors and certain executive officers of Landmark has simultaneously with the execution of this Agreement entered into a Support and Non-Competition Agreement (each a “Voting Agreement” and collectively, the “Voting Agreements”) in connection with the Merger, in the form of Exhibit A.

A-1

ARTICLE 2
MANNER OF CONVERTING SHARES

2.1. Conversion of Shares.

Subject to the provisions of this ARTICLE 2, at the Effective Time, by virtue of the Merger and without any action on the part of Simmons, Simmons Bank, Landmark or the shareholders of any of the foregoing, the shares of Landmark and Simmons shall be converted as follows (for the avoidance of doubt, the capital stock of Simmons Bank shall not be affected by the Merger):

(a) Each share of capital stock of Simmons issued and outstanding immediately prior to the Effective Time shall remain an issued and outstanding share of capital stock of Simmons from and after the Effective Time and shall not be affected by the Merger.

A-2

(b) Each share of Landmark capital stock issued and outstanding immediately prior to the Effective Time that is held by Landmark, any Landmark Subsidiary, Simmons or any Simmons Subsidiary (in each case other than shares held in any Employee Benefit Plans or related trust accounts or otherwise held in any fiduciary or agency capacity or as a result of debts previously contracted) (collectively, the “Canceled Shares”) shall automatically be canceled and retired and shall cease to exist, and no payment shall be made with respect thereto.

(c) Each share of Landmark Common Stock issued and outstanding immediately prior to the Effective Time (excluding the Canceled Shares and the Landmark Dissenting Shares), subject to Section 2.3(b), shall be converted into the right to receive, without interest:

(i) the Per Share Cash Consideration; and

(ii) the Per Share Stock Consideration.

(d) Each share of Landmark Common Stock, when so converted pursuant to Section 2.1(c), shall automatically be canceled and retired and shall cease to exist as of the Effective Time, and each certificate (an “Old Certificate”, it being understood that any reference herein to “Old Certificate” shall be deemed to include reference to book-entry account statements relating to ownership of shares of Landmark Common Stock (a “Book-Entry Share”)) registered in the transfer books of Landmark that immediately prior to the Effective Time represented shares of Landmark Common Stock shall thereafter cease to have any rights with respect to such Landmark Common Stock other than the right to receive the Merger Consideration in accordance with ARTICLE 3.

2.2. Anti-Dilution Provisions.

In the event Simmons changes the number of shares of Simmons Common Stock issued and outstanding between the date of this Agreement and the Effective Time as a result of a stock split, stock dividend, or similar recapitalization with respect to such stock and the record date therefor (in the case of a stock dividend) or the effective date thereof (in the case of a stock split or similar recapitalization for which a record date is not established) shall be between the date of this Agreement and the Effective Time, the Merger Consideration shall be equitably and proportionately adjusted, if necessary and without duplication, to reflect fully the effect of any such change.

2.3. Treatment of Landmark Equity Rights.

(a) At the Effective Time, each option granted by Landmark to purchase shares of Landmark Common Stock under the Landmark Non-Qualified Stock Option Plan, whether vested or unvested, that is outstanding and unexercised immediately prior to the Effective Time (a “Landmark Stock Option”) shall be canceled and converted into the right to receive from Simmons a cash payment (“Landmark Stock Option Payout”) equal to the applicable Landmark Stock Option Amount. Notwithstanding the foregoing, any Landmark Stock Option with an Option Exercise Price that equals or exceeds the Fully Diluted Per Share Value shall be canceled with no consideration being paid to the optionholder with respect to such Landmark Stock Option.

(b) Notwithstanding anything herein to the contrary, if the Cash Consideration is less than $0.00, then the Aggregate Cash Consideration shall be increased such that the Cash Consideration equals $0.00. The amount by which the Aggregate Cash Consideration is increased shall be referred to as the “Aggregate Cash Increase.” If the Aggregate Cash Consideration is increased, then the Stock Consideration shall be decreased by the number of shares of Simmons Common Stock equal to the quotient obtained by dividing the Aggregate Cash Increase by the Average Closing Price (for the avoidance of doubt, if the quotient includes a fractional share, then the quotient shall be rounded up to the next whole share (for example, if the quotient is 1,000.34, then the quotient shall be rounded up to 1,001)).

A-3

(c) Without limiting Section 7.8 hereof, the board of directors of Landmark or any committee thereof, as applicable, shall, prior to the Closing and effective as of no later than the day immediately prior to, and contingent upon, the Closing adopt any resolutions and take any actions, and cause any actions to be taken, that are necessary or, in the reasonable determination of Simmons, advisable to effectuate the provisions of this Section 2.3.

2.4. Fractional Shares.

No certificate, book-entry share or scrip representing fractional shares of Simmons Common Stock shall be issued upon the surrender for exchange of Old Certificates, no dividend or distribution with respect to Simmons Common Stock shall be payable on or with respect to any such fractional share interests, and such fractional share interests will not entitle the owner thereof to vote or to any other rights of a shareholder of Simmons. Notwithstanding any other provision of this Agreement, each holder of shares of Landmark Common Stock exchanged pursuant to the Merger who would otherwise have been entitled to receive a fraction of a share of Simmons Common Stock (after taking into account all Old Certificates delivered by such Holder) shall receive, in lieu thereof, a cash payment rounded up to the nearest whole cent (without interest), which payment shall be determined by multiplying (i) the fraction of a share (rounded to the nearest thousandth when expressed in decimal form) of Simmons Common Stock that such holder of shares of Landmark Common Stock would otherwise have been entitled to receive pursuant to Section 2.1(c) by (ii) the Average Closing Price (the “Fractional Share Payment”).

ARTICLE 3
EXCHANGE OF SHARES

3.1. Exchange Procedures.

(a) Deposit of Exchange Fund. At or promptly following the Effective Time, Simmons shall deposit, or shall cause to be deposited, with Computershare, Simmons’s transfer agent, or another exchange agent reasonably acceptable to Simmons (the “Exchange Agent”), for the benefit of the holders of record of shares of Landmark Common Stock (excluding the Canceled Shares) issued and outstanding immediately prior to the Effective Time (collectively, the “Holders”), for exchange in accordance with this ARTICLE 3, (i) certificates or, at Simmons’s option, evidence of Simmons Common Stock in book-entry form issuable pursuant to Section 2.1(c) (collectively referred to as “Simmons Certificates”) for shares of Simmons Common Stock equal to the Stock Consideration and (ii) immediately available funds for (A) the Cash Consideration, (B) any Fractional Share Payments to the extent then determinable and (C), after the Effective Time, if applicable, any dividends or distributions which such Holders have the right to receive pursuant to Section 3.1(d) (collectively, the “Exchange Fund”). Simmons shall instruct the Exchange Agent to timely pay the Exchange Fund in accordance with this Agreement. The cash portion of the Exchange Fund shall be invested by the Exchange Agent as directed by Simmons or the Surviving Bank. Interest and other income on the Exchange Fund shall be the sole and exclusive property of Simmons and the Surviving Bank and shall be paid to Simmons or the Surviving Bank, as Simmons directs. No investment of the Exchange Fund shall relieve Simmons, the Surviving Bank or the Exchange Agent from making the payments required by this Agreement and following any losses from any such investment, Simmons shall promptly provide additional funds to the Exchange Agent to the extent necessary to satisfy Simmons’s obligations hereunder for the benefit of the Holders, which additional funds will be deemed to be part of the Exchange Fund.

(b) Delivery of Merger Consideration. As soon as reasonably practicable after the Effective Time, the Exchange Agent shall mail to each Holder of an Old Certificate (including, for the avoidance of doubt, any Book-Entry Share, if required by the Exchange Agent or at the request of Simmons) a notice advising such Holders of the effectiveness of the Merger, including appropriate transmittal materials specifying that delivery shall be effected, and risk of loss and title to the Old Certificates (including, for the avoidance of doubt,

A-4

Book-Entry Shares, if applicable), shall pass, only upon proper delivery of the Old Certificates (including, for the avoidance of doubt, Book-Entry Shares, if applicable), and instructions for surrendering the Old Certificates (including, for the avoidance of doubt, Book-Entry Shares, if applicable), to the Exchange Agent (such materials and instructions to include customary provisions with respect to delivery of an “agent’s message” with respect to Book-Entry Shares). Upon proper surrender of an Old Certificate (including, for the avoidance of doubt, Book-Entry Shares, if applicable), for exchange and cancellation to the Exchange Agent, together with the appropriate transmittal materials, duly completed and validly executed in accordance with the instructions thereto, and such other documents as may be required pursuant to such instructions, the Holder of such Old Certificate shall be entitled to receive in exchange therefor the Merger Consideration and such Old Certificate so surrendered shall forthwith be canceled. No interest will be paid or accrued for the benefit of Holders on the Merger Consideration payable upon the surrender of the Old Certificates. The Per Share Stock Consideration delivered to each Holder shall be in non-certificated book-entry form.

(c) Share Transfer Books. At the Effective Time, the share transfer books of Landmark shall be closed, and thereafter there shall be no further registration of transfers of shares of Landmark Common Stock. From and after the Effective Time, Holders who held shares of Landmark Common Stock immediately prior to the Effective Time shall cease to have rights with respect to such shares, except as otherwise provided for herein. Until surrendered for exchange in accordance with the provisions of this Section 3.1, each Old Certificate (including, for the avoidance of doubt, each Book-Entry Share) theretofore representing shares of Landmark Common Stock (other than the Canceled Shares) shall from and after the Effective Time represent for all purposes only the right to receive the consideration provided in this Agreement in exchange therefor. On or after the Effective Time, any Old Certificates presented to the Exchange Agent, Simmons or the Surviving Bank for any reason shall be canceled and exchanged for the Merger Consideration.

(d) Dividends with Respect to Simmons Common Stock. No dividends or other distributions declared with respect to Simmons Common Stock with a record date after the Effective Time shall be paid to the Holder of any unsurrendered Old Certificate with respect to the whole shares of Simmons Common Stock issuable with respect to such Old Certificate in accordance with this Agreement until the surrender of such Old Certificate (or affidavit of loss in lieu thereof) in accordance with this Agreement. Subject to applicable Laws, following surrender of any such Old Certificate (or affidavit of loss and other documentation required by the Exchange Agent, Simmons, or the Surviving Bank hereunder in lieu thereof) there shall be paid to the record holder of the whole shares of Simmons Common Stock, if any, issued in exchange therefor, without interest, (i) all dividends and other distributions payable in respect of any such whole shares of Simmons Common Stock with a record date after the Effective Time and a payment date on or prior to the date of such surrender and not previously paid and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to such surrender and with a payment date subsequent to such surrender payable with respect to such shares of Simmons Common Stock.

(e) Termination of Exchange Fund. Any portion of the Exchange Fund (including any interest and other income received with respect thereto) which remains undistributed to the former Holders on the first anniversary of the Effective Time shall be delivered to Simmons; and any former Holders who have not theretofore received any Merger Consideration to which they are entitled under this Agreement shall thereafter look only to Simmons and the Surviving Bank for payment of their claims with respect thereto.

(f) No Liability. If any Old Certificates shall not have been surrendered (or canceled) prior to three years after the Effective Time (or immediately prior to such earlier date on which the Merger Consideration would escheat to or become the property of any Regulatory Authority), any such Merger Consideration in respect thereof shall, to the extent permitted by applicable Law, become the property of Simmons, free and clear of all claims or interest of any Person previously entitled thereto or their successors, assigns, or personal representatives. None of Simmons, Landmark, the Surviving Bank or the Exchange Agent, or any employee, officer, director, agent or Affiliate of any of them, shall be liable to any Holder in respect of any amount that

A-5

would have otherwise been payable in respect of any Old Certificate from the Exchange Fund delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

(g) Withholding Rights. Each and any of Simmons, the Surviving Bank or the Exchange Agent, as applicable, shall be entitled to deduct and withhold from the Merger Consideration, Landmark Stock Option Payouts, or any other amounts or property otherwise payable or distributable to any Person pursuant to this Agreement, such amounts or property (or portions thereof) as Simmons, the Surviving Bank or the Exchange Agent is required to deduct and withhold with respect to the making of such payment or distribution under the Internal Revenue Code, and the rules and regulations promulgated thereunder, or any provision of applicable Tax Law. Any amounts so deducted or withheld and remitted to the appropriate Regulatory Authority by Simmons, the Surviving Bank, or the Exchange Agent, as applicable, shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction and withholding was made by Simmons, the Surviving Bank, or the Exchange Agent, as applicable.

(h) Lost Old Certificates. If any Old Certificate shall have been lost, stolen or destroyed, then upon the making of an affidavit of that fact by the Person claiming such Old Certificate, as applicable, to be lost, stolen or destroyed and, if required by the Exchange Agent, Simmons, or the Surviving Bank, the posting by such Person of a bond in such reasonable and customary amount as the Exchange Agent, Simmons, or the Surviving Bank may direct, as indemnity against any claim that may be made against it with respect to such Old Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Old Certificate the Merger Consideration to which the Holder thereof is entitled pursuant to this Agreement.

(i) Change in Name on Old Certificate. If any Simmons Certificate is to be issued in a name other than that in which the Old Certificates surrendered (or canceled) in exchange therefor is or are registered, it shall be a condition of the issuance thereof that the Old Certificates so surrendered (or canceled) shall be properly endorsed (or accompanied by an appropriate instrument of transfer) and otherwise in proper form for transfer, and that the Person requesting such exchange shall pay to the Exchange Agent, Simmons or the Surviving Bank in advance any transfer or other similar Taxes required by reason of the issuance of a Simmons Certificate in any name other than that of the registered Holder of the Old Certificates surrendered (or canceled), or required for any other reason, or shall establish to the satisfaction of the Exchange Agent, Simmons and the Surviving Bank that such Tax has been paid or is not payable.

3.2. Dissenting Shareholders.

(a) Notwithstanding anything in this Agreement to the contrary, shares of Landmark Common Stock that are issued and outstanding immediately prior to the Effective Time and which are held by any Holder who is entitled to demand and properly demands appraisal of such shares of Landmark Common Stock pursuant to, and who complies in all respects with, the provisions of Section 48-23-101 et seq. of the Tennessee Business Corporation Act (“Section 48-23-101 et seq.”) (the “Landmark Dissenting Shareholders”), shall not be converted into or be exchangeable for the right to receive any of the consideration as specified in this Agreement (the “Landmark Dissenting Shares”), but instead such Holder shall be entitled to payment of the fair value of such Landmark Dissenting Shares in accordance with the provisions of Section 48-23-101 et seq. At the Effective Time, all Landmark Dissenting Shares shall no longer be outstanding, shall automatically be canceled and retired and shall cease to exist, and each Holder of Landmark Dissenting Shares shall cease to have any rights with respect thereto, except the right to receive the fair value of such Landmark Dissenting Shares in accordance with the provisions of Section 48-23-101 et seq. Notwithstanding the foregoing, if any such Holder shall fail to perfect or otherwise shall waive, withdraw or lose the right to appraisal under Section 48-23-101 et seq., or a court of competent jurisdiction shall determine that such Holder is not entitled to the relief provided by Section 48-23-101 et seq., then the right of such Holder to be paid the fair value of such Holder’s Landmark Dissenting Shares under Section 48-23-101 et seq. shall cease and such Landmark Dissenting Shares shall be deemed to have been converted at the Effective Time into, and shall have become, the right to receive the Merger Consideration.

A-6

(b) Landmark shall give Simmons prompt written notice (but in any event within two Business Days) of any demands for appraisal of any shares of Landmark Common Stock and any withdrawals of such demands, and Simmons shall have the right to participate in and direct all negotiations and proceedings with respect to such demands. Landmark shall not, except with the prior written consent of Simmons, voluntarily make any payment with respect to, or settle, or offer or agree to settle, any such demand for payment.

ARTICLE 4

Landmark is authorized by the Tennessee Department of Financial Institutions (“TDFI”) and the Federal Deposit Insurance Corporation (the “FDIC”) to engage in the business of banking as a state-chartered bank. Landmark is in good standing in each jurisdiction in which its ownership of Assets or conduct of business requires such qualification, except where failure to be so qualified has not had or would not reasonably be expected to have, either individually or in the aggregate, a Material Adverse Effect on Landmark. True, complete and correct copies of the Charter and Bylaws of Landmark, each as in effect as of the date of this Agreement, have been delivered or made available to Simmons. The Charter and Bylaws of Landmark comply with applicable Law.

4.2. Authority of Landmark; No Breach by Agreement.

The execution, delivery, and performance of this Agreement and the consummation of the transactions contemplated herein, including the Merger, have been duly and validly authorized and approved by all necessary corporate action in respect thereof on the part of Landmark (including approval by and a determination by all of the members of the board of directors of Landmark that this Agreement is advisable and in the best interests of Landmark’s shareholders and directing the submission of this Agreement to a vote at a meeting of shareholders of Landmark), subject to the Landmark Shareholder Approval. This Agreement has been duly executed and delivered by Landmark. Subject to the Landmark Shareholder Approval, and assuming the due authorization, execution and delivery by Simmons and Simmons Bank, this Agreement represents a legal, valid, and binding obligation of Landmark, enforceable against Landmark in accordance with its terms (except in all cases as such enforceability may be limited by applicable bankruptcy, insolvency, fraudulent transfer, reorganization, receivership, conservatorship, moratorium, or similar Laws affecting the enforcement of creditors’ rights generally and except that the availability of the equitable remedy of specific performance or injunctive relief is subject to the discretion of the court before which any proceeding may be brought (the “Bankruptcy and Equity Exceptions”)).

(b) No Conflicts. Subject to the receipt of the Landmark Shareholder Approval, neither the execution and delivery of this Agreement by Landmark nor the consummation by Landmark of the transactions contemplated hereby, nor compliance by Landmark with any of the provisions hereof, will (i) conflict with or result in a breach of any provision of the Charter, Bylaws or other governing instruments of Landmark, or any

A-7

resolution adopted by the board of directors or the shareholders of any Landmark Entity, or (ii) subject to receipt of the Requisite Regulatory Approvals, (x) violate any Law applicable to any Landmark Entity or any of their respective Assets or (y) violate, conflict with, constitute or result in a Default under or the loss of any benefit under, or result in the creation of any Lien upon any of the respective Assets of any Landmark Entity under any of the terms, conditions or provisions of any Contract or Permit of any Landmark Entity or under which any of their respective Assets may be bound, except in the case of clause (y) above where such violations, conflicts or Defaults have not had or would not reasonably be expected to have, either individually or in the aggregate, a Material Adverse Effect on Landmark and subject to the receipt of the consents of counterparties to the Contracts listed in Section 4.2 of Landmark’s Disclosure Memorandum (the “Contract Consents”).

As of the date hereof, Landmark has no Knowledge of any reason why the Requisite Regulatory Approvals will not be received in order to permit consummation of the Merger on a timely basis.

4.18. Employee Benefit Plans.

(a) Landmark has made available to Simmons prior to the execution of this Agreement, true, complete and correct copies of each Employee Benefit Plan (including all amendments thereto), that has been adopted, maintained, sponsored in whole or in part by, or contributed to or required to be contributed to by any Landmark Entity or Landmark ERISA Affiliate for the benefit of employees, retirees, dependents, spouses, directors, independent contractors, or other beneficiaries or under which employees, retirees, former employees, dependents, spouses, directors, independent contractors, or other beneficiaries are eligible to participate or with respect to which Landmark or any Landmark ERISA Affiliate has or may have any obligation or Liability (each, a “Landmark Benefit Plan”). For the avoidance of doubt, the term “Landmark Benefit Plans” includes plans, programs, policies, and arrangements sponsored or maintained by a third-party professional employer organization in which the current or former employees, retirees, dependents, spouses, directors, Independent Contractors, or other beneficiaries of a Landmark Entity or any of its affiliates are eligible to participate. Section 4.18(a) of Landmark’s Disclosure Memorandum has a complete and accurate list of all Landmark Benefit Plans. No Landmark Benefit Plan is subject to any Laws other than those of the United States or any state, county, or municipality in the United States. Landmark has made available to Simmons prior to the execution of this Agreement (i) all trust agreements or other funding arrangements for all Landmark Benefit Plans, (ii) all determination letters, opinion letters, information letters or advisory opinions issued by the IRS, the DOL or the Pension Benefit Guaranty Corporation (“PBGC”) during this calendar year or any of the preceding three calendar years, (iii) annual reports or returns, audited or unaudited financial statements, actuarial reports and valuations prepared for any Landmark Benefit Plan for the current plan year and the preceding plan year, (iv) the most recent summary plan descriptions and any material modifications thereto, (v) any correspondence with the DOL, IRS, PBGC, or any other governmental entity regarding a Landmark Benefit Plan, and (vi) all actuarial valuations of Landmark Benefit Plans.

No Landmark Benefit Plan is required to be amended within the 90-day period beginning on the Closing Date in order to continue to comply with ERISA, the Internal Revenue Code,

A-19

and other applicable Law. Each Landmark Benefit Plan that is intended to be qualified under Section 401(a) of the Internal Revenue Code is so qualified and has received a favorable determination letter, or for a prototype plan, opinion letter, from the IRS that is still in effect and applies to the Landmark Benefit Plan and on which such Landmark Benefit Plan is entitled to rely. Nothing has occurred and no circumstance exists that would be reasonably expected to adversely affect the qualified status of such Landmark Benefit Plan. Within the past three years, no Landmark Entity has taken any action to take material corrective action or make a filing under any voluntary correction program of the IRS, DOL or any other Regulatory Authority with respect to any Landmark Benefit Plan. All assets of each Landmark Benefit Plan that is a retirement plan consist exclusively of cash and actively traded securities.

(c) There are no threatened or pending claims or disputes under the terms of, or in connection with, the Landmark Benefit Plans other than claims for benefits in the Ordinary Course that are not expected to result in material liability to any Landmark Entity, and no action, proceeding, prosecution, inquiry, hearing or investigation or audit has been commenced with respect to any Landmark Benefit Plan.

No Landmark Entity, Landmark Entity employee, nor any committee of which any Landmark Entity employee is a member has breached his or her fiduciary duty with respect to a Landmark Benefit Plan in connection with any acts taken (or failed to be taken) with respect to the administration or investment of the assets of any Landmark Benefit Plan. To Landmark’s Knowledge, no fiduciary, within the meaning of Section 3(21) of ERISA, who is not Landmark Entity or any Landmark Entity employee, has breached his or her fiduciary duty with respect to a Landmark Benefit Plan or otherwise has any Liability in connection with any acts taken (or failed to be taken) with respect to the administration or investment of the assets of any Landmark Benefit Plan. The treatment of the awards of Landmark Equity Rights as required under Section 2.3 of this Agreement is permitted by applicable Law and the terms of the applicable plan and award agreement.

(e) Neither Landmark nor any Landmark ERISA Affiliate has at any time been a party to or maintained, sponsored, contributed to or has been obligated to contribute to, or had any Liability with respect to, or would reasonably be expected to have any such obligation to contribute to or Liability with respect to: (i) a plan subject to Title IV of ERISA, Section 302 of ERISA, or Section 412 of the Internal Revenue Code; (ii) a “multiemployer plan” (as defined in ERISA Section 3(37) and 4001(a)(3)); (iii) a “multiple employer plan” (as defined in 29 C.F.R. § 4001.2) or a plan subject to Section 413(c) of the Internal Revenue Code; (iv) a “multiple employer welfare arrangement” (as defined in Section 3(40) of ERISA or applicable state law); (v) a self-funded health or welfare benefit plan; or (vi) any voluntary employees’ beneficiary association (within the meaning of Section 501(c)(9) of the Internal Revenue Code).

(f) Each Landmark Benefit Plan or other arrangement of a Landmark Entity that is a “nonqualified deferred compensation plan” within the meaning of Section 409A of the Internal Revenue Code has a plan document that satisfies the requirements of Section 409A of the Internal Revenue Code and has been operated in compliance with the terms of such plan document and the requirements of Section 409A of the Internal Revenue Code, in each case such that no Tax is or has been due or payable under Section 409A of the Internal Revenue Code.

(g) Each Landmark Benefit Plan that is a health or welfare plan has been amended and administered in accordance with the requirements of the Patient Protection and Affordable Care Act of 2010. No Landmark Entity has any Liability or obligation to provide postretirement health, medical or life insurance benefits to any Landmark Entity’s employees or former employees, officers, or directors, or any dependent or beneficiary

A-20

thereof, except as otherwise required under state or federal benefits continuation Laws and for which the covered individual pays the full cost of coverage. No Tax under Internal Revenue Code Sections 4980, 4980B through 4980I, or 5000 has been incurred with respect to any Landmark Benefit Plan and no circumstance exists which could give rise to such Tax.

(h) None of the Landmark Benefit Plans are subject to Title IV of ERISA.

(i) All contributions required to be made to any Landmark Benefit Plan by applicable Law or by any plan document or other contractual undertaking, and all premiums due or payable with respect to insurance policies funding any Landmark Benefit Plan, for any period through the date hereof, have been timely made or paid in full or, to the extent not required to be made or paid on or before the date hereof, have been fully reflected on the Books and Records of Landmark.

(j) Neither the execution and delivery of this Agreement nor the consummation of the transactions contemplated hereby will (either alone or in conjunction with any other event) result in, cause the vesting, exercisability or delivery of, or increase in the amount or value of, any payment, right or other benefit to any employee, officer, director or other service provider of any Landmark Entity, or result in any (a) requirement to fund any benefits or set aside benefits in a trust (including a rabbi trust), (b) limitation on the right of any Landmark Entity to amend, merge, terminate or receive a reversion of assets from any Landmark Benefit Plan or related trust, (c) acceleration of the time of payment or vesting of any such payment, right, compensation or benefit, or (d) entitlement by any recipient of any payment or benefit to receive a “gross up” payment for any income or other Taxes that might be owed with respect to such payment or benefit. Without limiting the generality of the foregoing, no amount paid or payable (whether in cash, in property, or in the form of benefits) by the Landmark Entities in connection with the transactions contemplated hereby (either solely as a result thereof or as a result of such transactions in conjunction with any other event) will be an “excess parachute payment” within the meaning of Section 280G of the Internal Revenue Code. Section 4.18(j) of Landmark’s Disclosure Memorandum sets forth accurate and complete data with respect to each individual who has a contractual right to severance pay or benefits (or increase in severance pay or benefits, including the acceleration of any payment or vesting) triggered by a change in control and the amounts potentially payable to each such individual in connection with the execution and delivery of this Agreement or the consummation of the transactions contemplated hereby (either alone or in conjunction with any other event) or as a result of a termination of employment or service, taking into account any contractual provisions relating to Section 280G of the Internal Revenue Code. No Landmark Benefit Plan provides for, and no Landmark Entity has any obligation or commit to provide, the gross-up or reimbursement of Taxes under Internal Revenue Code Section 4999 or 409A, or otherwise.

ADDITIONAL AGREEMENTS

7.1. Registration Statement; Proxy Statement/Prospectus; Shareholder Approvals.

(a) Simmons and Landmark shall promptly prepare and file with the SEC, a proxy statement/prospectus in definitive form (including any amendments thereto, the “Proxy Statement/Prospectus”) and Simmons shall prepare and file with the SEC the Registration Statement (including the Proxy Statement/Prospectus constituting a part thereof and all related documents) as promptly as reasonably practicable after the date of this Agreement, subject to full cooperation of both Parties and their respective advisors and accountants. Simmons and Landmark agree to cooperate, and to cause their respective Subsidiaries to cooperate, with the other Party and its counsel and its accountants in the preparation of the Registration Statement and the Proxy Statement/Prospectus.

A-38

practicable after filing thereof, and Landmark shall thereafter mail or deliver the Proxy Statement/Prospectus to its shareholders promptly following the date of effectiveness of the Registration Statement. Simmons also agrees to use its reasonable best efforts to obtain all necessary state securities law or “Blue Sky” permits and approvals required to carry out the transactions contemplated by this Agreement, and Landmark shall furnish all information concerning Landmark and the holders of Landmark Common Stock as may be reasonably requested in connection with any such action.

(b) Landmark shall duly call, give notice of, establish a record date for, convene and hold a shareholders’ meeting (“Landmark’s Shareholders’ Meeting”), to be held as promptly as reasonably practicable after the Registration Statement is declared effective by the SEC, for the purpose of obtaining the Landmark Shareholder Approval and, if so desired and mutually agreed, such other matters of the type customarily brought before an annual or special meeting of shareholders. Landmark agrees that its obligations pursuant to this Section 7.1(b) shall not be affected by the commencement, proposal, disclosure, or communication to Landmark of any Acquisition Proposal.

Landmark shall also adjourn or postpone Landmark’s Shareholders’ Meeting if, as of the time for which Landmark’s Shareholders’ Meeting is scheduled, Landmark has not recorded proxies representing a sufficient number of shares necessary to obtain the Landmark Shareholder Approval. If requested by Simmons, Landmark shall retain a proxy solicitor reasonably acceptable to, and on terms reasonably acceptable to, Simmons in connection with obtaining the Landmark Shareholder Approval. Notwithstanding anything to the contrary herein, Landmark’s Shareholders’ Meeting shall be convened and this Agreement shall be submitted to the shareholders of Landmark at Landmark’s Shareholders’ Meeting, for the purpose of voting on the approval of this Agreement and the other matters contemplated hereby, and nothing contained herein shall be deemed to relieve Landmark of such obligation.

7.2. Acquisition Proposals.

(a) No Landmark Entity shall, and it shall cause its Representatives not to, directly or indirectly, (i) solicit, initiate, encourage (including by providing information or assistance), facilitate or induce any Acquisition Proposal, (ii) engage or participate in any discussions or negotiations regarding, or furnish or cause to be furnished to any Person any confidential or nonpublic information or data with respect to, or take any other action to facilitate any inquiries or the making of any offer or proposal that constitutes, or may reasonably be expected to lead to, an Acquisition Proposal (iii) adopt, approve, agree to, accept, endorse or recommend any Acquisition Proposal, (iv) approve, agree to, accept, endorse or recommend, or propose to approve, agree to,

accept, endorse or recommend any Acquisition Agreement contemplating or otherwise relating to any Acquisition Transaction, or (v) otherwise cooperate in any way with, or assist or participate in, or facilitate or encourage any effort or attempt by any Person to do or seek to do any of the foregoing. Without limiting the foregoing, it is agreed that any violation of the restrictions set forth in this Section 7.2 by any Subsidiary or Representative of Landmark shall constitute a breach of this Section 7.2 by Landmark. In addition to the foregoing, Landmark shall not submit to the vote of its shareholders any Acquisition Proposal other than the Merger.

(b) Promptly (but in no event more than 24 hours) following receipt of any Acquisition Proposal or any request for nonpublic information or any inquiry that could reasonably be expected to lead to any Acquisition Proposal, Landmark shall advise Simmons in writing of the receipt of such Acquisition Proposal, request or inquiry, and the terms and conditions of such Acquisition Proposal, request or inquiry (including, in each case, the identity of the Person making any such Acquisition Proposal, request or inquiry), and Landmark shall as promptly as practicable provide to Simmons (i) a copy of such Acquisition Proposal, request or inquiry, if in writing, or (ii) a written summary of the material terms of such Acquisition Proposal, request or inquiry, if oral. Landmark shall provide Simmons as promptly as practicable (but in no event more than 24 hours) with notice setting forth all such information as is necessary to keep Simmons informed on a current basis of all developments, discussions, negotiations and communications regarding (including amendments or proposed amendments to) such Acquisition Proposal, request or inquiry.

(c) Notwithstanding anything herein to the contrary, at any time prior to Landmark’s Shareholders’ Meeting, the board of directors of Landmark may submit this Agreement to Landmark’s shareholders without recommendation (although the resolution approving this Agreement as of the date hereof may not be rescinded or amended), if (i) Landmark has received a Superior Proposal (after giving effect to the terms of any revised offer by Simmons pursuant to this Section 7.2(c)), and (ii) the board of directors of Landmark has determined in good faith, after consultation with its financial advisors and outside legal counsel, that it would be a violation of the directors’ fiduciary duties under applicable Law to make or continue to make the Landmark Recommendation; provided, that the board of directors of Landmark may not take the actions set forth in this Section 7.2(c) unless:

(i) Landmark has complied in all material respects with this Section 7.2;

(ii) Landmark has provided Simmons at least five Business Days prior written notice of its intention to take such action and a reasonable description of the events or circumstances giving rise to its determination to take such action (including all necessary information under Section 7.2(b));

(iii) during such five Business Day period, Landmark has and has caused its financial advisors and outside legal counsel to consider and negotiate with Simmons in good faith (to the extent Simmons desires to so negotiate) regarding any proposals, adjustments or modifications to the terms and conditions of this Agreement proposed by Simmons; and

(iv) the board of directors of Landmark has determined in good faith, after consultation with its financial advisors and outside legal counsel and considering the results of such negotiations and giving effect to any proposals, amendments or modifications proposed to by Simmons, if any, that such Superior Proposal remains a Superior Proposal and that it would nevertheless be a violation of the director’s fiduciary duties under applicable Law to make or continue to make the Landmark Recommendation.

Any material amendment to any Acquisition Proposal, will be deemed to be a new Acquisition Proposal for purposes of this Section 7.2(c) and will require a new determination and notice period as referred to in this Section 7.2(c).

A-40

(d) Landmark and Landmark Subsidiaries shall, and Landmark shall direct its Representatives to, (i) immediately cease and cause to be terminated any and all existing activities, discussions or negotiations with any Persons conducted heretofore with respect to any offer or proposal that constitutes, or may reasonably be expected to lead to, an Acquisition Proposal, (ii) request the prompt return or destruction of all confidential information previously furnished to any Person (other than Simmons, Simmons Bank and their Representatives) that has made or indicated an intention to make an Acquisition Proposal, (iii) not waive or amend any “standstill” provision or provisions of similar effect to which it is a party or of which it is a beneficiary and shall strictly enforce any such provisions.

7.3. Exchange Listing.

Simmons shall use its reasonable best efforts to list, prior to the Effective Time, on Nasdaq, subject to official notice of issuance, the shares of Simmons Common Stock to be issued to the holders of Landmark Common Stock pursuant to this Agreement, and Simmons shall give all notices and make all filings with Nasdaq required in connection with the transactions contemplated herein.

7.4. Consents of Regulatory Authorities.

(a) The Parties and their respective Subsidiaries shall cooperate with each other and use their respective reasonable best efforts to prepare all documentation, to effect all applications, notices, petitions, and filings and to obtain all Permits and Consents of all third parties and Regulatory Authorities that are necessary or advisable to consummate the transactions contemplated by this Agreement (including the Merger), and to comply with the terms and conditions of all such Permits and Consents. Each of the Parties shall use its respective reasonable best efforts to resolve objections, if any, which may be asserted with respect to this Agreement or the transactions contemplated hereby by any Regulatory Authority or under any applicable Law or Order. Notwithstanding the foregoing, in no event shall any Simmons Entities be required, and the Landmark Entities shall not be permitted (without Simmons’s prior written consent in its sole discretion), to take any action, or commit to take any action, or to accept any restriction or condition, involving the Simmons Entities or the Landmark Entities, which is materially burdensome on Simmons’s or Simmons Bank’s business or on the business of Landmark, in each case following the Closing, or which would likely reduce the economic benefits of the transactions contemplated by this Agreement to Simmons or Simmons Bank to such a degree that Simmons would not have entered into this Agreement had such condition or restriction been known to it at the date hereof (any such condition or restriction, a “Burdensome Condition”).

(b) Each of the Parties shall have the right to review in advance, and to the extent practicable each will consult with the other, in each case subject to applicable Laws relating to the exchange of information, with respect to, all material written information submitted to any third party or Regulatory Authority in connection with the transactions contemplated by this Agreement; provided, that Landmark shall not have the right to review portions of material filed by Simmons or Simmons Bank with a Regulatory Authority that contain competitively sensitive business or other proprietary information or confidential supervisory information. In exercising the foregoing rights, each of the Parties agrees to act reasonably and as promptly as practicable. Each Party agrees that it will consult with the other Party with respect to the obtaining of all Permits and Consents of third parties and Regulatory Authorities necessary or advisable to consummate the transactions contemplated by this Agreement and each Party will keep the other Party apprised of the status of material matters relating to completion of the transactions contemplated hereby, including advising the other Party upon receiving any communication from a Regulatory Authority the Consent of which is required for the consummation of the Merger and the other transactions contemplated by this Agreement that causes such Party to believe that there is a reasonable likelihood that any Requisite Regulatory Approval will not be obtained or that the receipt of such Requisite Regulatory Approval may be materially delayed.

A-41

(c) Each Party agrees, upon request, subject to applicable Laws, to promptly furnish the other Party with all information concerning itself, its Subsidiaries, directors, officers and shareholders and such other matters as may be reasonably necessary or advisable in connection with the Registration Statement, Proxy/Prospectus or any other statement, filing, notice or application made by or on behalf of Simmons, Landmark or any of their respective Subsidiaries to any third party and/or Regulatory Authority in connection with the transactions contemplated by this Agreement.

7.5. Access to Information; Confidentiality and Notification of Certain Matters.

(a) Landmark shall promptly advise Simmons and Simmons Bank of any fact, change, event, effect, condition, occurrence, development or circumstance (i) that has had or would reasonably be expected to have, either individually or in the aggregate, a Material Adverse Effect on Landmark or (ii) which Landmark believes would or would be reasonably likely to cause or constitute a material breach of any of its representations, warranties, covenants or agreements contained herein or that reasonably could be expected to give rise, individually or in the aggregate, to the failure of a condition in ARTICLE 8; provided, that any failure to give notice in accordance with the foregoing with respect to any breach shall not be deemed to constitute a violation of this Section 7.5(a) or the failure of any condition set forth in Section 8.2 or 8.3 to be satisfied, or otherwise constitute a breach of this Agreement by the Party failing to give such notice, in each case unless the underlying breach would independently result in a failure of the conditions set forth in Section 8.2 or 8.3 to be satisfied; and provided, further, that the delivery of any notice pursuant to this Section 7.5(a) shall not cure any breach of, or noncompliance with, any other provision of this Agreement or limit the remedies available to Simmons or Simmons Bank.

(b) Prior to the Effective Time, Landmark shall permit the Representatives of Simmons and Simmons Bank to make or cause to be made such investigation of the business, Assets, information technology systems, Contracts, Books and Records, and personnel and such other information of it and its Subsidiaries and of their respective financial and legal conditions as Simmons and Simmons Bank reasonably request and furnish to Simmons and Simmons Bank promptly all other information concerning its business, Assets, information technology systems, Contracts, Books and Records, and personnel and such other information as Simmons and Simmons Bank may reasonably request, provided that such investigation or requests shall not interfere unnecessarily with normal operations of Landmark. No investigation by Simmons or Simmons Bank shall affect or be deemed to modify or waive the representations, warranties, covenants and agreements of Landmark in this Agreement, or the conditions of such Party’s obligation to consummate the transactions contemplated by this Agreement. Neither Simmons nor Landmark nor any of their respective Subsidiaries shall be required to provide access to or to disclose information where such access or disclosure would violate or prejudice the rights of Simmons’s or Landmark’s, as the case may be, customers, jeopardize the attorney-client privilege of the institution in possession or control of such information (after giving due consideration to the existence of any common interest, joint defense or similar agreement between the Parties) or contravene any Law, fiduciary duty or binding Contract entered into prior to the date of this Agreement. The Parties will make appropriate substitute disclosure arrangements under circumstances in which the restrictions of the preceding sentence apply. Without limiting the foregoing, and for the avoidance of doubt, subject to applicable Law, Landmark shall permit the Representatives of Simmons and Simmons Bank to observe meetings of committees or similar groups established to review and approve potential Loans or similar matters.

(c) Each Party shall, and shall cause its Subsidiaries and Representatives to, hold any information obtained in connection with this Agreement in accordance with the terms of the Mutual Nondisclosure Agreement, dated February 3, 2021, between Simmons and Landmark (the “Confidentiality Agreement”).

(d) Prior to the Effective Time, Landmark shall promptly notify Simmons and Simmons Bank of any material change in the normal course of its business or in the operation of its properties and, to the extent permitted by applicable Law, of any material Litigation (or communications indicating that the same may be

A-42

contemplated), or the institution or the threat of a material Litigation involving Landmark or any other Landmark Entity. In addition, Landmark shall engage third parties reasonably satisfactory to Landmark, Simmons and Simmons Bank, at Simmons’s or Simmons Bank’s expense, to conduct such reviews of Landmark’s regulatory compliance program as Simmons or Simmons Bank may reasonably request, and, subject to Section 10.15, Landmark shall disclose the results of those reviews to Simmons and Simmons Bank.

7.6. Press Releases.

The Parties shall consult with each other before issuing any press release or other public disclosure or communication (including communications to employees, agents and contractors) related to this Agreement or the transactions contemplated hereby and shall not issue such press release or other public disclosure without the prior written consent of the other Party (which consent shall not be unreasonably withheld, delayed or conditioned); provided, that nothing in this Section 7.6 shall be deemed to prohibit any Party from making any press release or other public disclosure as may upon the advice of the Party’s outside counsel be required by Law or the rules or regulations of any United States or non-United States securities exchange, in which case the Party required to make the release or disclosure shall use its reasonable best efforts to allow the other Party reasonable time to comment on such release or disclosure in advance of the issuance thereof. The Parties have agreed upon the form of a joint press release announcing the execution of this Agreement.

7.7. Tax Treatment.

(a) Each of the Parties intends, and undertakes and agrees to use its respective reasonable best efforts to cause, the Merger, and to take no action which would cause the Merger not, to qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code for federal income Tax purposes, and none of the Parties shall take any action that would cause the Merger to not so qualify. The Parties shall cooperate and use their reasonable best efforts in order to obtain the Tax Opinion. The Parties adopt this Agreement as a “plan of reorganization” within the meaning of Treasury Regulations Section 1.368-2(g) and for purposes of Sections 354, 361 and 368 of the Internal Revenue Code.

(b) Each of the Parties shall use its respective reasonable best efforts to cause their appropriate officers to execute and deliver to Covington certificates containing appropriate representations and covenants, reasonably satisfactory in form and substance to Covington, at such time or times as may be reasonably requested by Covington, including as of the effective date of the Proxy Statement/Prospectus and the Closing Date, in connection with such counsel’s deliveries of opinions with respect to the Tax treatment of the Merger.

(c) Unless otherwise required pursuant to a “determination” within the meaning of Section 1313(a) of the Internal Revenue Code, each Party shall report the Merger as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code and shall not take any inconsistent position therewith in any Tax Return.

(d) Prior to Closing, Landmark shall (i) deliver to Simmons and mail to the IRS in accordance with Treasury Regulation Section 1.897-2(h) (1) a statement, in form and substance satisfactory to Simmons, certifying that every Landmark Entity is not, and has not been during the applicable period specified in Section 897(c)(1)(A)(ii) of the Internal Revenue Code, a “United States real property holding company” within the meaning of Section 897(c)(2) of the Internal Revenue Code, which statement shall satisfy the requirements of Treasury Regulations Sections 1.897-2(h) and 1.1445-2(c)(3), together with (2) a notice prepared and executed in accordance with Treasury Regulations Section 1.897-2(h) to the IRS; and (ii) together therewith, furnish to Simmons proof of mailing the items described in subclause (i).

A-43

7.8. Employee Benefits and Contracts.

(a) For a period of one year following the Effective Time, except as contemplated by this Agreement, Simmons or Simmons Bank shall provide generally to employees who are actively employed by a Landmark Entity on the Closing Date (“Covered Employees”) while employed by Simmons or Simmons Bank following the Closing Date employee benefits under Simmons Benefit Plans, on terms and conditions which are, in the aggregate, substantially comparable to those provided by Simmons Entities to their similarly situated employees; provided, that in no event shall any Covered Employee be eligible to participate in any closed or frozen plan of any Simmons Entity. Until such time as Simmons or Simmons Bank shall cause the Covered Employees to participate in the applicable Simmons Benefit Plans, the continued participation of the Covered Employees in the Landmark Benefit Plans shall be deemed to satisfy the foregoing provisions of this clause (it being understood that participation in Simmons Benefit Plans may commence at different times with respect to each of Simmons Benefit Plans). For purposes of determining eligibility to participate and vesting under Simmons Benefit Plans, and for purposes of determining a Covered Employee’s entitlement to paid time off under Simmons’s or Simmons Bank’s paid time off program, the service of the Covered Employees with a Landmark Entity prior to the Effective Time shall be treated as service with a Simmons Entity participating in such Simmons Benefit Plans, to the same extent that such service was formally recognized by the Landmark Entities for purposes of a similar benefit plan; provided, that such recognition of service shall not (i) operate to duplicate any benefits of a Covered Employee with respect to the same period of service or (ii) apply for purposes of any plan, program or arrangement (x) under which similarly-situated employees of Simmons Entities do not receive credit for prior service, (y) that is grandfathered or frozen, either with respect to level of benefits or participation, or (z) for purposes of retiree medical benefits or level of benefits under a defined benefit pension plan.

(b) Prior to the Closing Date, the Landmark Entities shall take all necessary action (including without limitation the adoption of resolutions and plan amendments and the delivery of any required notices) to terminate, effective as of no later than the day before the Closing Date, any Landmark Benefit Plan that is intended to constitute a tax-qualified defined contribution plan under Internal Revenue Code Section 401(k) (a “401(k) Plan”). Landmark shall provide Simmons with a copy of the resolutions, plan amendments, notices and other documents prepared to effectuate the termination of the 401(k) Plans in advance and give Simmons a reasonable opportunity to comment on such documents (which comments shall be considered in good faith), and prior to the Closing Date, Landmark shall provide Simmons with the final documentation evidencing that the 401(k) Plans have been terminated.

(c) Upon request by Simmons in writing prior to the Closing Date, the Landmark Entities shall cooperate in good faith with Simmons prior to the Closing Date to amend, freeze, terminate or modify any other Landmark Benefit Plan to the extent and in the manner determined by Simmons effective upon the Closing Date (or at such different time mutually agreed to by the Parties) and consistent with applicable Law. Landmark shall provide Simmons with a copy of the resolutions, plan amendments, notices and other documents prepared to effectuate the actions contemplated by this Section 7.8(c), as applicable, and give Landmark a reasonable opportunity to comment on such documents (which comments shall be considered in good faith), and prior to the Closing Date, Landmark shall provide Simmons with the final documentation evidencing that the actions contemplated herein have been effectuated.

(d) Without limiting the generality of Section 10.4, nothing in this Agreement, expressed or implied, is intended to confer upon any Person, including any current or former employee, officer, director or consultant of Landmark or any of its Subsidiaries or Affiliates, any rights, remedies, obligations, or liabilities under or by reason of this Agreement. In no event shall the terms of this Agreement: (i) establish, amend, or modify any Landmark Benefit Plan or any “employee benefit plan” as defined in Section 3(3) of ERISA, or any other benefit plan, program, agreement or arrangement maintained or sponsored by Simmons, Landmark or any of their respective Affiliates; (ii) alter or limit the ability of the Surviving Bank, Simmons or any

A-44

of their Subsidiaries or Affiliates to amend, modify or terminate any Landmark Benefit Plan, employment agreement or any other benefit or employment plan, program, agreement or arrangement after the Closing Date; or (iii) confer upon any current or former employee, officer, director or consultant of Landmark or any of its Subsidiaries or Affiliates, any right to employment or continued employment or continued service with Simmons or any Simmons Subsidiaries, the Surviving Bank or the Landmark Entities, or constitute or create an employment agreement with any employee, or interfere with or restrict in any way the rights of the Surviving Bank, Landmark, Simmons or any Subsidiary or Affiliate thereof to discharge or terminate the services of any employee, officer, director or consultant of Landmark or any of its Subsidiaries or Affiliates at any time for any reason whatsoever, with or without cause.

(e) On the Closing Date, Landmark shall provide Simmons with a list of employees who have suffered an “employment loss” (as defined in the WARN Act) in the 90 days preceding the Closing Date or had a reduction in hours of a least 50% in the 180 days preceding the Closing Date, each identified by date of employment loss or reduction in hours, employing entity and facility location.

7.9. Indemnification.

(a) For a period of six years after the Effective Time, the Surviving Bank shall indemnify, defend and hold harmless the present and former directors or officers of the Landmark Entities (each, an “Indemnified Party”), against all Liabilities incurred in connection with any Litigation arising out of or pertaining to, the fact that such person is or was a director or officer of the Landmark Entities or, at Landmark’s request, of another corporation, partnership, joint venture, trust or other enterprise and pertaining to matters, acts or omissions existing or occurring at or prior to the Effective Time (including matters, acts or omissions occurring in connection with the approval of this Agreement and the transactions contemplated by this Agreement) (each a “Claim”), whether asserted or claimed prior to, at or after the Effective Time, to the fullest extent permitted under the Charter and Bylaws of Landmark as in effect as of the date of this Agreement (subject to applicable Law), including provisions relating to advances of expenses incurred in the defense of any Litigation; provided, that the Indemnified Party to whom expenses are advanced provides a written undertaking to repay such advances if it is ultimately determined that such Indemnified Party is not entitled to indemnification.

(b) The Surviving Bank shall use its reasonable best efforts (and Landmark shall cooperate prior to the Effective Time in these efforts) to maintain in effect for a period of six years after the Effective Time Landmark’s existing directors’ and officers’ liability insurance policy (provided that the Surviving Bank may substitute therefor (i) policies of at least the same coverage and amounts containing terms and conditions which are substantially no less advantageous to the insured or (ii) with the consent of Landmark given prior to the Effective Time, any other policy) with respect to claims arising from facts or events which occurred prior to the Effective Time; provided, that the Surviving Bank shall not be obligated to make aggregate premium payments for such six-year period in respect of such policy (or coverage replacing such policy) which exceed, for the portion related to Landmark’s directors and officers, 200% of the annual premium payments currently paid on Landmark’s current policy in effect as of the date of this Agreement (the “Maximum Amount”). If the amount of the premiums necessary to maintain or procure such insurance coverage exceeds the Maximum Amount, the Surviving Bank shall use its reasonable best efforts to maintain the most advantageous policies of directors’ and officers’ liability insurance obtainable for a premium equal to the Maximum Amount. In lieu of the foregoing, Simmons, or Landmark in consultation with Simmons, may obtain on or prior to the Effective Time, a six-year “tail” prepaid policy providing equivalent coverage to that described in this Section 7.9(b) at a premium not to exceed the Maximum Amount. If the premium necessary to purchase such “tail” prepaid policy exceeds the Maximum Amount, Simmons or Landmark in consultation with Simmons may purchase the most advantageous “tail” prepaid policy obtainable for a premium equal to the Maximum Amount, and in each case, Simmons and the Surviving Bank shall have no further obligations under this Section 7.9(b) other than to maintain such “tail” prepaid policy.

(c) Any Indemnified Party wishing to claim indemnification under Section 7.9(a), upon learning of any such Claim, shall promptly notify the Surviving Bank thereof.

(d) If the Surviving Bank or any successors or assigns shall consolidate with or merge into any other Person and shall not be the continuing or surviving Person of such consolidation or merger or if the Surviving Bank (or any successors or assigns) shall transfer all or substantially all of its Assets to any Person, then and in each case, proper provision shall be made so that the successors and assigns of the Surviving Bank shall assume the obligations set forth in this Section 7.9.

(e) The provisions of this Section 7.9 are intended to be for the benefit of and shall be enforceable by, each Indemnified Party and their respective heirs and Representatives.

(f) Notwithstanding anything in this Section 7.9 to the contrary, no indemnification payments will be made to an Indemnified Party with respect to an administrative proceeding or civil action initiated by any federal banking agency unless all of the following conditions are met: (i) the Simmons Bank’s board of directors determines in writing that the Indemnified Party acted in good faith and in the best interests of Landmark; (ii) the Simmons Bank’s board of directors determines that the payment will not materially affect the Simmons Bank’s safety and soundness; (iii) the payment does not fall within the definition of a prohibited indemnification payment under 12 C.F.R. Part 359; and (iv) the Indemnified Party agrees in writing to reimburse Simmons Bank, to the extent not covered by permissible insurance, for payments made in the event that the administrative or civil action instituted by a banking Regulatory Authority results in a final order or settlement in which the Indemnified Party is assessed a civil money penalty, is prohibited from banking, or is required to cease an action or perform an affirmative action.

7.17. Takeover Statutes.

If the Termination Fee shall be payable pursuant to subsection (i) of this Section 10.3(b), the Termination Fee shall be paid in same-day funds at or prior to the earlier of the date of consummation of such Acquisition Transaction or the date of execution of an Acquisition Agreement with respect to such Acquisition Transaction. If the Termination Fee shall be payable pursuant to subsection (ii) of this Section 10.3(b), the Termination Fee shall be paid in same-day funds within two Business Days from the date of termination of this Agreement.

(c) The payment of the Termination Fee by Landmark pursuant to Section 10.3(b) constitutes liquidated damages and not a penalty, and shall be the sole monetary remedy of Simmons, in the event of termination of this Agreement pursuant to Sections 9.1(b)(ii), 9.1(c), 9.1(d) or 9.1(e). The Parties acknowledge that the agreements contained in Section 10.3(b) are an integral part of the transactions contemplated by this Agreement, and that without these agreements, they would not enter into this Agreement; accordingly, if Landmark fails to pay any fee payable by it pursuant to this Section 10.3 when due, then Landmark shall pay to

A-66

Simmons its costs and expenses (including attorneys’ fees) in connection with collecting such fee, together with interest on the amount of the fee at the prime rate of Citibank, N.A. from the date such payment was due under this Agreement until the date of payment.

10.4. Entire Agreement; No Third Party Beneficiaries.

Except as otherwise expressly provided herein, this Agreement (including the Disclosure Memorandum of each of Landmark and Simmons, the Exhibits, the schedules, and the other documents and instruments referred to herein) together with the Confidentiality Agreement and the Voting Agreements constitute the entire agreement between the Parties with respect to the transactions contemplated hereunder and thereunder and supersedes all prior arrangements or understandings with respect thereto, written or oral. Nothing in this Agreement (including the documents and instruments referred to herein) expressed or implied, is intended to confer upon any Person, other than the Parties or their respective successors, any rights, remedies, obligations, or liabilities under or by reason of this Agreement, other than as specifically provided in Section 7.9. The representations and warranties in this Agreement are the product of negotiations among the Parties and are for the sole benefit of the Parties. Any inaccuracies in such representations and warranties are subject to waiver by the Parties in accordance herewith without notice or liability to any other Person. In some instances, the representations and warranties in this Agreement may represent an allocation among the Parties of risks associated with particular matters regardless of the knowledge of any of the Parties. Consequently, Persons other than the Parties may not rely upon the representations and warranties in this Agreement as characterizations of actual facts or circumstances as of the date of this Agreement or as of any other date. Notwithstanding any other provision hereof to the contrary, no consent, approval or agreement of any third-party beneficiary will be required to amend, modify to waive any provision of this Agreement.

10.5. Amendments.

To the extent permitted by Law, this Agreement may be amended by a subsequent writing signed by each of the Parties upon the approval of each of the Parties, whether before or after the Landmark Shareholder Approval has been obtained; provided, that after obtaining the Landmark Shareholder Approval, there shall be made no amendment that requires further approval by such Landmark shareholders.

10.6. Waivers.

At any time prior to the Effective Time, the Parties, by action taken or authorized by their respective boards of directors, may, to the extent permitted by Law, (a) extend the time for the performance of any of the obligations or other acts of the other Parties, (b) waive any inaccuracies in the representations and warranties contained herein or in any document delivered pursuant hereto, and (c) waive compliance with any of the agreements or satisfaction of any conditions contained herein; provided, that after the Landmark Shareholder Approval has been obtained, there may not be, without further approval of such shareholders, any extension or waiver of this Agreement or any portion thereof that requires further approval under applicable Law. Any agreement on the part of a Party to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such Party, but such extension or waiver or failure to insist on strict compliance with an obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure to comply with an obligation, covenant, agreement or condition.

10.7. Assignment.

Except as expressly contemplated hereby, neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any Party (whether by operation of Law or otherwise) without the prior written consent of the other Party. Any purported assignment in contravention hereof shall be null and void. Subject to the preceding sentences, this Agreement will be binding upon, inure to the benefit of and be enforceable by the Parties and their respective successors and assigns.

A-67

10.8. Notices.

10.9. Governing Law; Jurisdiction; Waiver of Jury Trial

(a) The Parties agree that this Agreement shall be governed by and construed in all respects in accordance with the Laws of the State of Arkansas without regard to any conflict of Laws or choice of Law principles that might otherwise refer construction or interpretation of this Agreement to the substantive Law of another jurisdiction (except that matters relating to the fiduciary duties of the board of directors of Landmark shall be subject to the Laws of the State of Tennessee).

(b) Each Party agrees that it will bring any action or proceeding in respect of any claim arising out of or related to this Agreement or the transactions contemplated hereby exclusively in any federal or state court of competent jurisdiction located in the State of Arkansas (the “Chosen Courts”), and, solely in connection with claims arising under this Agreement or the transactions that are the subject of this Agreement, (i) irrevocably submits to the exclusive jurisdiction of the Chosen Courts, (ii) waives any objection to laying venue in any such action or proceeding in the Chosen Courts, (iii) waives any objection that the Chosen Courts are an inconvenient forum or do not have jurisdiction over any party, and (iv) agrees that service of process upon such party in any such action or proceeding will be effective if notice is given in accordance with Section 10.8.

(c) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY SUIT, ACTION OR OTHER PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT: (I) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF ANY ACTION, SUIT OR PROCEEDING, SEEK TO ENFORCE THE FOREGOING WAIVER, (II) EACH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (III) EACH PARTY MAKES THIS WAIVER VOLUNTARILY, AND (IV) EACH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 10.9.

10.10. Counterparts; Signatures.

This Agreement may be executed in two or more counterparts, each of which shall be deemed to be an original, but all of which together shall constitute one and the same instrument. This Agreement and any signed agreement or instrument entered into in connection with this Agreement, and any amendments or waivers hereto or thereto, to the extent signed and delivered by means of a facsimile machine or by e-mail delivery of a “.pdf” format data file, shall be treated in all manner and respects as an original agreement or instrument and shall be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. No Party or to any such agreement or instrument shall raise the use of a facsimile machine or e-mail delivery of a “.pdf” format data file to deliver a signature to this Agreement or any amendment or waiver hereto or any agreement or instrument entered into in connection with this Agreement or the fact that any signature or agreement or instrument was transmitted or communicated through the use of a facsimile machine or e-mail delivery of a “.pdf” format data file as a defense to the formation of a contract and each Party forever waives any such defense.

10.11. Captions; Articles and Sections.

The captions contained in this Agreement are for reference purposes only and are not part of this Agreement. Unless otherwise indicated, all references to particular Articles or Sections shall mean and refer to the referenced Articles and Sections of this Agreement.

A-69

10.12. Interpretations.

Neither this Agreement nor any uncertainty or ambiguity herein shall be construed or resolved against any Party, whether under any rule of construction or otherwise. No Party shall be considered the draftsman. The Parties acknowledge and agree that this Agreement has been reviewed, negotiated, and accepted by all Parties and their attorneys and, unless otherwise defined herein, the words used shall be construed and interpreted according to their ordinary meaning so as fairly to accomplish the purposes and intentions of all Parties.

10.13. Enforcement of Agreement.

The Parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement was not performed in accordance with its specific terms or was otherwise breached and that money damages would be both incalculable and an insufficient remedy for any breach of this Agreement. It is accordingly agreed that the Parties shall be entitled, without the requirement of posting bond, to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any court of the United States or any state having jurisdiction, this being in addition to any other remedy to which they are entitled at law or in equity. Each of the Parties waives any defense in any action for specific performance that a remedy at law would be adequate.

10.14. Severability.

Any term or provision of this Agreement which is invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement or affecting the validity or enforceability of any of the terms or provisions of this Agreement in any other jurisdiction. If any provision of this Agreement is so broad as to be unenforceable, the provision shall be interpreted to be only so broad as is enforceable.

10.15. Confidential Supervisory Information.

Notwithstanding any other provision of this Agreement, no disclosure, representation or warranty shall be made (or other action taken) pursuant to this Agreement that would involve the disclosure of confidential supervisory information as defined in 12 C.F.R. § 261.2(b) and as identified in 12 C.F.R. § 309.5 (g)(8) of a Regulatory Authority by any Party to the extent prohibited by applicable Law. To the extent legally permissible, appropriate substitute disclosures or actions shall be made or taken under circumstances in which the limitations of the preceding sentence apply.

Under the terms and subject to the conditions of this Agreement and in accordance with applicable provisions of the Arkansas Business Corporation Act of 1987 (the “ABCA”) and the Tennessee Business Corporation Act (the “TBCA”), Triumph will merge with and into Simmons (the “Merger”), with Simmons as the surviving corporation in the Merger (sometimes referred to in such capacity as the “Surviving Corporation”).

As a condition and an inducement for Simmons to enter into this Agreement, certain of the directors and executive officers of Triumph have simultaneously with the execution of this Agreement entered into a Support and Non-Competition Agreement (each a “Voting Agreement” and collectively, the “Voting Agreements”) in connection with the Merger, in substantially the form of Exhibit A.

The Parties intend that the Merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code, and the Parties intend that this Agreement will be adopted as a “plan of reorganization” within the meaning of Sections 354 and 361 of the Internal Revenue Code.

The Parties desire to make certain representations, warranties, covenants and agreements in connection with the Merger and also to prescribe certain conditions to the Merger.

Capitalized terms used in this Agreement and not otherwise defined herein are defined in Section 10.1 of this Agreement.

ARTICLE 2
MANNER OF CONVERTING SHARES

| 2.1 | Conversion of Shares.

Subject to the provisions of this ARTICLE 2, at the Effective Time, by virtue of the Merger and without any action on the part of Simmons, Triumph or the shareholders of either of the foregoing, the shares of Triumph and Simmons shall be converted as follows:

(a) Each share of capital stock of Simmons issued and outstanding immediately prior to the Effective Time shall remain an issued and outstanding share of capital stock of Simmons from and after the Effective Time and shall not be affected by the Merger.

(b) Each share of Triumph capital stock issued and outstanding immediately prior to the Effective Time that is held by Triumph, any Triumph Subsidiary, Simmons or any Simmons Subsidiary (in each case other than shares held in any Employee Benefit Plans or related trust accounts or otherwise held in any fiduciary or agency capacity or as a result of debts previously contracted) (collectively, the “Canceled Shares”) shall automatically be canceled and retired and shall cease to exist, and no payment shall be made with respect thereto.

(c) Each share of Triumph Common Stock issued and outstanding immediately prior to the Effective Time (excluding the Canceled Shares and the Triumph Dissenting Shares), subject to Sections 2.3(b), 2.5, and 9.1(g), shall be converted into the right to receive, without interest:

| (i) | the Per Share Cash Consideration; and

| (ii) | the Per Share Stock Consideration.

(d) Each share of Triumph Common Stock, when so converted pursuant to Section 2.1(c), shall automatically be canceled and retired and shall cease to exist as of the Effective Time, and each certificate (an “Old Certificate”, it being understood that any reference herein to “Old Certificate” shall be deemed to include reference to book-entry account statements relating to ownership of shares of Triumph Common Stock (a “Book-Entry Share”)) registered in the transfer books of Triumph that immediately prior to the Effective Time represented shares of Triumph Common Stock shall thereafter cease to have any rights with respect to such Triumph Common Stock other than the right to receive the Merger Consideration in accordance with ARTICLE 3.

| 2.2 | Anti-Dilution Provisions.

In the event Simmons changes the number of shares of Simmons Common Stock issued and outstanding between the date of this Agreement and the Effective Time as a result of a stock split, stock dividend, or similar recapitalization with respect to such stock and the record date therefor (in the case of a stock dividend) or the effective date thereof (in the case of a stock split or similar recapitalization for which a record date is not established) shall be between the date of this Agreement and the Effective Time, the Merger Consideration shall be equitably and proportionately adjusted, if necessary and without duplication, to reflect fully the effect of any such change.

| 2.3 | Treatment of Triumph Equity Rights.

(a) At the Effective Time, each option granted by Triumph to purchase shares of Triumph Common Stock under the (i) Triumph 2006 Incentive and Non-Qualified Stock Option Plan, (ii) Triumph 2012 Incentive and Non-Qualified Stock Option Plan, or (iii) Triumph 2017 Incentive and Non-Qualified Stock Option Plan, whether vested or unvested, that is outstanding and unexercised immediately prior to the Effective Time

B-3

(a “Triumph Stock Option”) shall be canceled and converted into the right to receive from Simmons a cash payment (“Triumph Stock Option Payout”) equal to the applicable Triumph Stock Option Amount. Notwithstanding the foregoing, any Triumph Stock Option with an Option Exercise Price that equals or exceeds the Fully Diluted Per Share Value shall be canceled with no consideration being paid to the optionholder with respect to such Triumph Stock Option.

(b) Notwithstanding anything herein to the contrary, if the Cash Consideration is less than $0.00, then the Aggregate Cash Consideration shall be increased such that the Cash Consideration equals $0.00. The amount by which the Aggregate Cash Consideration is increased shall be referred to as the “Aggregate Cash Increase” If the Aggregate Cash Consideration is increased, then the Stock Consideration shall be decreased by the number of shares of Simmons Common Stock equal to the quotient obtained by dividing the Aggregate Cash Increase by the Average Closing Price (for the avoidance of doubt, if the quotient includes a fractional share, then the quotient shall be rounded up to the next whole share (for example, if the quotient is 1,000.34, then the quotient shall be rounded up to 1,001)). For the avoidance of doubt, any adjustments in the Aggregate Cash Consideration or the Stock Consideration pursuant to this Section 2.3(b) shall be independent of, and shall be applied after giving effect to, any adjustments pursuant to Sections 2.5 or 9.1(g) (if applicable).

(c) Without limiting Section 7.8 hereof, the board of directors of Triumph or any committee thereof, as applicable, shall, prior to the Closing and effective as of no later than the day immediately prior to, and contingent upon, the Closing, adopt any resolutions and take any actions, and cause any actions to be taken, that are necessary or, in the reasonable determination of Simmons, advisable to effectuate the provisions of this Section 2.3.

| 2.4 | Fractional Shares.

No certificate, book-entry share or scrip representing fractional shares of Simmons Common Stock shall be issued upon the surrender for exchange of Old Certificates, no dividend or distribution with respect to Simmons Common Stock shall be payable on or with respect to any such fractional share interests, and such fractional share interests will not entitle the owner thereof to vote or to any other rights of a shareholder of Simmons. Notwithstanding any other provision of this Agreement, each holder of shares of Triumph Common Stock exchanged pursuant to the Merger who would otherwise have been entitled to receive a fraction of a share of Simmons Common Stock (after taking into account all Old Certificates delivered by such Holder) shall receive, in lieu thereof, a cash payment rounded up to the nearest whole cent (without interest), which payment shall be determined by multiplying (i) the fraction of a share (rounded to the nearest thousandth when expressed in decimal form) of Simmons Common Stock that such holder of shares of Triumph Common Stock would otherwise have been entitled to receive pursuant to Section 2.1(c) by (ii) the Average Closing Price (the “Fractional Share Payment”).

| 2.5 | Pricing Adjustments.

(a) If, as of the Determination Date, both of the following conditions are satisfied:

| (i) | the Average Closing Price is greater than $37.28; and

| (ii) | the difference between (A) the quotient obtained by dividing (1) the Average Closing Price by (2) $31.07 and (B) the quotient obtained by dividing (1) the average of the closing prices of the Nasdaq Bank Index (as reported in The Wall Street Journal or, if not reported thereby, another alternative source as chosen by Simmons) for the 20 consecutive full trading days ending on and including the Determination Date by (2) $4,489.83, is greater than 0.20 (or 20%),

B-4

then the Stock Consideration shall be decreased by the number of whole shares of Simmons Common Stock so that, as a result of such adjustment, the sum of (i) the product obtained by multiplying the Stock Consideration by the Average Closing Price and (ii) the Aggregate Cash Consideration shall be no more than the Maximum Merger Consideration. “Maximum Merger Consideration” shall be the sum of (i) the product of (x) $37.28 and (y) the Stock Consideration and (ii) the Aggregate Cash Consideration.

(b) In lieu of the adjustment described in paragraph (a) of this section, Simmons may make such other adjustments to the Aggregate Cash Consideration and the Stock Consideration as it deems appropriate, so long as, following such adjustments, the sum of (i) the product obtained by multiplying the Stock Consideration by the Average Closing Price and (ii) the Aggregate Cash Consideration shall be no more than the Maximum Merger Consideration.

ARTICLE 3
EXCHANGE OF SHARES

| 3.1 | Exchange Procedures.

(a) Deposit of Exchange Fund. At or promptly following the Effective Time, Simmons shall deposit, or shall cause to be deposited, with Computershare, Simmons’s transfer agent, or another exchange agent reasonably acceptable to Simmons (the “Exchange Agent”), for the benefit of the holders of record of shares of Triumph Common Stock (excluding the Canceled Shares) issued and outstanding immediately prior to the Effective Time (collectively, the “Holders”), for exchange in accordance with this ARTICLE 3, (i) certificates or, at Simmons’s option, evidence of Simmons Common Stock in book-entry form issuable pursuant to Section 2.1(c) (collectively referred to as “Simmons Certificates”) for shares of Simmons Common Stock equal to the Stock Consideration and (ii) immediately available funds for (A) the Cash Consideration, (B) any Fractional Share Payments to the extent then determinable and (C), after the Effective Time, if applicable, any dividends or distributions which such Holders have the right to receive pursuant to Section 3.1(d) (collectively, the “Exchange Fund”). Simmons shall instruct the Exchange Agent to timely pay the Exchange Fund in accordance with this Agreement. The cash portion of the Exchange Fund shall be invested by the Exchange Agent as directed by Simmons or the Surviving Corporation. Interest and other income on the Exchange Fund shall be the sole and exclusive property of Simmons and the Surviving Corporation and shall be paid to Simmons or the Surviving Corporation, as Simmons directs. No investment of the Exchange Fund shall relieve Simmons, the Surviving Corporation or the Exchange Agent from making the payments required by this Agreement and following any losses from any such investment, Simmons shall promptly provide additional funds to the Exchange Agent to the extent necessary to satisfy Simmons’s obligations hereunder for the benefit of the Holders, which additional funds will be deemed to be part of the Exchange Fund.

(b) Delivery of Merger Consideration. As soon as reasonably practicable after the Effective Time, the Exchange Agent shall mail to each Holder of an Old Certificate (including, for the avoidance of doubt, any Book-Entry Share, if required by the Exchange Agent or at the request of Simmons) a notice advising such Holders of the effectiveness of the Merger, including appropriate transmittal materials specifying that delivery shall be effected, and risk of loss and title to the Old Certificates (including, for the avoidance of doubt, Book-Entry Shares, if applicable), shall pass, only upon proper delivery of the Old Certificates (including, for the avoidance of doubt, Book-Entry Shares, if applicable), and instructions for surrendering the Old Certificates (including, for the avoidance of doubt, Book-Entry Shares, if applicable), to the Exchange Agent (such materials and instructions to include customary provisions with respect to delivery of an “agent’s message” with respect to Book-Entry Shares). Upon proper surrender of an Old Certificate (including, for the avoidance of doubt, Book-Entry Shares, if applicable), for exchange and cancellation to the Exchange Agent, together with the appropriate transmittal materials, duly completed and validly executed in accordance with the instructions thereto, and such other documents as may be required pursuant to such instructions, the Holder of such Old Certificate shall be entitled to receive in exchange therefor the Merger Consideration and such Old Certificate so surrendered shall

B-5

forthwith be canceled. No interest will be paid or accrued for the benefit of Holders on the Merger Consideration payable upon the surrender of the Old Certificates. The Per Share Stock Consideration delivered to each Holder shall be in non-certificated book-entry form.

(c) Share Transfer Books. At the Effective Time, the share transfer books of Triumph shall be closed, and thereafter there shall be no further registration of transfers of shares of Triumph Common Stock. From and after the Effective Time, Holders who held shares of Triumph Common Stock immediately prior to the Effective Time shall cease to have rights with respect to such shares, except as otherwise provided for herein. Until surrendered for exchange in accordance with the provisions of this Section 3.1, each Old Certificate (including, for the avoidance of doubt, each Book-Entry Share) theretofore representing shares of Triumph Common Stock (other than the Canceled Shares) shall from and after the Effective Time represent for all purposes only the right to receive the consideration provided in this Agreement in exchange therefor. On or after the Effective Time, any Old Certificates presented to the Exchange Agent, Simmons or the Surviving Corporation for any reason shall be canceled and exchanged for the Merger Consideration.

(d) Dividends with Respect to Simmons Common Stock. No dividends or other distributions declared with respect to Simmons Common Stock with a record date after the Effective Time shall be paid to the Holder of any unsurrendered Old Certificate with respect to the whole shares of Simmons Common Stock issuable with respect to such Old Certificate in accordance with this Agreement until the surrender of such Old Certificate (or affidavit of loss in lieu thereof) in accordance with this Agreement. Subject to applicable Laws, following surrender of any such Old Certificate (or affidavit of loss and other documentation required by the Exchange Agent, Simmons, or the Surviving Corporation hereunder in lieu thereof) there shall be paid to the record holder of the whole shares of Simmons Common Stock, if any, issued in exchange therefor, without interest, (i) all dividends and other distributions payable in respect of any such whole shares of Simmons Common Stock with a record date after the Effective Time and a payment date on or prior to the date of such surrender and not previously paid and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to such surrender and with a payment date subsequent to such surrender payable with respect to such shares of Simmons Common Stock.

(e) Termination of Exchange Fund. Any portion of the Exchange Fund (including any interest and other income received with respect thereto) which remains undistributed to the former Holders on the first anniversary of the Effective Time shall be delivered to Simmons; and any former Holders who have not theretofore received any Merger Consideration to which they are entitled under this Agreement shall thereafter look only to Simmons and the Surviving Corporation for payment of their claims with respect thereto.

(f) No Liability. If any Old Certificates shall not have been surrendered (or canceled) prior to three years after the Effective Time (or immediately prior to such earlier date on which the Merger Consideration would escheat to or become the property of any Regulatory Authority), any such Merger Consideration in respect thereof shall, to the extent permitted by applicable Law, become the property of Simmons, free and clear of all claims or interest of any Person previously entitled thereto or their successors, assigns, or personal representatives. None of Simmons, Triumph, the Surviving Corporation or the Exchange Agent, or any employee, officer, director, agent or Affiliate of any of them, shall be liable to any Holder in respect of any amount that would have otherwise been payable in respect of any Old Certificate from the Exchange Fund delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

(g) Withholding Rights. Each and any of Simmons, the Surviving Corporation or the Exchange Agent, as applicable, shall be entitled to deduct and withhold from the Merger Consideration, Triumph Stock Option Payouts, or any other amounts or property otherwise payable or distributable to any Person pursuant to this Agreement, such amounts or property (or portions thereof) as Simmons, the Surviving Corporation or the Exchange Agent is required to deduct and withhold with respect to the making of such payment or distribution under the Internal Revenue Code, and the rules and regulations promulgated thereunder, or any provision of

B-6

applicable Tax Law. Any amounts so deducted or withheld and remitted to the appropriate Regulatory Authority by Simmons, the Surviving Corporation, or the Exchange Agent, as applicable, shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction and withholding was made by Simmons, the Surviving Corporation, or the Exchange Agent, as applicable.

(h) Lost Old Certificates. If any Old Certificate shall have been lost, stolen or destroyed, then upon the making of an affidavit of that fact by the Person claiming such Old Certificate, as applicable, to be lost, stolen or destroyed and, if required by the Exchange Agent, Simmons, or the Surviving Corporation, the posting by such Person of a bond in such reasonable and customary amount as the Exchange Agent, Simmons, or the Surviving Corporation may direct, as indemnity against any claim that may be made against it with respect to such Old Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Old Certificate the Merger Consideration to which the Holder thereof is entitled pursuant to this Agreement.

(i) Change in Name on Old Certificate. If any Simmons Certificate is to be issued in a name other than that in which the Old Certificates surrendered (or canceled) in exchange therefor is or are registered, it shall be a condition of the issuance thereof that the Old Certificates so surrendered (or canceled) shall be properly endorsed (or accompanied by an appropriate instrument of transfer) and otherwise in proper form for transfer, and that the Person requesting such exchange shall pay to the Exchange Agent, Simmons or the Surviving Corporation in advance any transfer or other similar Taxes required by reason of the issuance of a Simmons Certificate in any name other than that of the registered Holder of the Old Certificates surrendered (or canceled), or required for any other reason, or shall establish to the satisfaction of the Exchange Agent, Simmons and the Surviving Corporation that such Tax has been paid or is not payable.

| 3.2 | Dissenting Shareholders.

(a) Notwithstanding anything in this Agreement to the contrary, shares of Triumph Common Stock that are issued and outstanding immediately prior to the Effective Time and which are held by any Holder who is entitled to demand and properly demands appraisal of such shares of Triumph Common Stock pursuant to, and who complies in all respects with, the provisions of Section 48-23-101 et seq. of the TBCA (“Section 48-23-101 et seq.”) (the “Triumph Dissenting Shareholders”), shall not be converted into or be exchangeable for the right to receive any of the consideration as specified in this Agreement (the “Triumph Dissenting Shares”), but instead such Holder shall be entitled to payment of the fair value of such Triumph Dissenting Shares in accordance with the provisions of Section 48-23-101 et seq. At the Effective Time, all Triumph Dissenting Shares shall no longer be outstanding, shall automatically be canceled and retired and shall cease to exist, and each Holder of Triumph Dissenting Shares shall cease to have any rights with respect thereto, except the right to receive the fair value of such Triumph Dissenting Shares in accordance with the provisions of Section 48-23-101 et seq. Notwithstanding the foregoing, if any such Holder shall fail to perfect or otherwise shall waive, withdraw or lose the right to appraisal under Section 48-23-101 et seq., or a court of competent jurisdiction shall determine that such Holder is not entitled to the relief provided by Section 48-23-101 et seq., then the right of such Holder to be paid the fair value of such Holder’s Triumph Dissenting Shares under Section 48-23-101 et seq. shall cease and such Triumph Dissenting Shares shall be deemed to have been converted at the Effective Time into, and shall have become, the right to receive the Merger Consideration.

(b) Triumph shall give Simmons prompt written notice (but in any event within 48 hours) of any demands for appraisal of any shares of Triumph Common Stock and any withdrawals of such demands, and Simmons shall have the right to participate in and direct all negotiations and proceedings with respect to such demands. Triumph shall not, except with the prior written consent of Simmons, voluntarily make any payment with respect to, or settle, or offer or agree to settle, any such demand for payment.

Neither the board of directors of Triumph nor any committee thereof shall (A) withhold, withdraw, qualify or modify in a manner adverse to Simmons the Triumph Recommendation, (B) fail to make the Triumph Recommendation or otherwise submit this Agreement to Triumph’s shareholders without recommendation, (C) adopt, approve, agree to, accept, recommend or endorse an Acquisition Proposal, (D) fail to publicly and without qualification (1) recommend against any Acquisition Proposal or (2) reaffirm the Triumph Recommendation within ten Business Days (or such fewer number of days as remains prior to Triumph’s Shareholders’ Meeting) after an Acquisition Proposal is made public or any request by Simmons to do so, (E) take any action, or make any public statement, filing or release inconsistent with the Triumph Recommendation, or (F) publicly propose to do any of the foregoing (any of the foregoing being a “Change in the Triumph Recommendation”).

(d) Triumph shall adjourn or postpone Triumph’s Shareholders’ Meeting, if, as of the time for which such meeting is originally scheduled, there are insufficient shares of Triumph Common Stock represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of such meeting. Triumph shall also adjourn or postpone Triumph’s Shareholders’ Meeting if, as of the time for which Triumph’s Shareholders’ Meeting is scheduled, Triumph has not recorded proxies representing a sufficient number of shares necessary to obtain the Triumph Shareholder Approval. Notwithstanding anything to the contrary herein,

B-40

Triumph’s Shareholders’ Meeting shall be convened and this Agreement shall be submitted to the shareholders of Triumph at Triumph’s Shareholders’ Meeting, for the purpose of voting on the approval of this Agreement and the other matters contemplated hereby, and nothing contained herein shall be deemed to relieve Triumph of such obligation.

| 7.2 | Acquisition Proposals.

(a) No Triumph Entity shall, and it shall cause its Representatives not to, directly or indirectly, (i) solicit, initiate, encourage (including by providing information or assistance), facilitate or induce any Acquisition Proposal, (ii) engage or participate in any discussions or negotiations regarding, or furnish or cause to be furnished to any Person any confidential or nonpublic information or data with respect to, or take any other action to facilitate any inquiries or the making of any offer or proposal that constitutes, or may reasonably be expected to lead to, an Acquisition Proposal, (iii) adopt, approve, agree to, accept, endorse or recommend any Acquisition Proposal, (iv) approve, agree to, accept, endorse or recommend, or propose to approve, agree to, accept, endorse or recommend any Acquisition Agreement contemplating or otherwise relating to any Acquisition Transaction, or (v) otherwise cooperate in any way with, or assist or participate in, or facilitate or encourage any effort or attempt by any Person to do or seek to do any of the foregoing. Without limiting the foregoing, it is agreed that any violation of the restrictions set forth in this Section 7.2 by any Subsidiary or Representative of Triumph shall constitute a breach of this Section 7.2 by Triumph. In addition to the foregoing, Triumph shall not submit to the vote of its shareholders any Acquisition Proposal other than the Merger.

(b) Promptly (but in no event more than 24 hours) following receipt of any Acquisition Proposal or any request for nonpublic information or any inquiry that could reasonably be expected to lead to any Acquisition Proposal, Triumph shall advise Simmons in writing of the receipt of such Acquisition Proposal, request or inquiry, and the terms and conditions of such Acquisition Proposal, request or inquiry (including, in each case, the identity of the Person making any such Acquisition Proposal, request or inquiry), and Triumph shall as promptly as practicable provide to Simmons (i) a copy of such Acquisition Proposal, request or inquiry, if in writing, or (ii) a written summary of the material terms of such Acquisition Proposal, request or inquiry, if oral. Triumph shall provide Simmons as promptly as practicable (but in no event more than 24 hours) with notice setting forth all such information as is necessary to keep Simmons informed on a current basis of all developments, discussions, negotiations and communications regarding (including amendments or proposed amendments to) such Acquisition Proposal, request or inquiry.

(c) Notwithstanding anything herein to the contrary, at any time prior to Triumph’s Shareholders’ Meeting, the board of directors of Triumph may submit this Agreement to Triumph’s shareholders without recommendation (although the resolution approving this Agreement as of the date hereof may not be rescinded or amended), if (i) Triumph has received a Superior Proposal (after giving effect to the terms of any revised offer by Simmons pursuant to this Section 7.2(c)), and (ii) the board of directors of Triumph has determined in good faith, after consultation with its financial advisors and outside legal counsel, that it would be a violation of the directors’ fiduciary duties under applicable Law to make or continue to make the Triumph Recommendation; provided, that the board of directors of Triumph may not take the actions set forth in this Section 7.2(c) unless:

| (i) | Triumph has complied in all material respects with this Section 7.2;

| (ii) | Triumph has provided Simmons at least five Business Days prior written notice of its intention to take such action and a reasonable description of the events or circumstances giving rise to its determination to take such action (including all necessary information under Section 7.2(b));

| (iii) | during such five Business Day period, Triumph has and has caused its financial advisors and outside legal counsel to consider and negotiate with Simmons in

B-41

|  | good faith (to the extent Simmons desires to so negotiate) regarding any proposals, adjustments or modifications to the terms and conditions of this Agreement proposed by Simmons; and
| (iv) | the board of directors of Triumph has determined in good faith, after consultation with its financial advisors and outside legal counsel and considering the results of such negotiations and giving effect to any proposals, amendments or modifications proposed to by Simmons, if any, that such Superior Proposal remains a Superior Proposal and that it would nevertheless be a violation of the director’s fiduciary duties under applicable Law to make or continue to make the Triumph Recommendation.

Any material amendment to any Acquisition Proposal, will be deemed to be a new Acquisition Proposal for purposes of this Section 7.2(c) and will require a new determination and notice period as referred to in this Section 7.2(c).

(d) Triumph and Triumph Subsidiaries shall, and Triumph shall direct its Representatives to, (i) immediately cease and cause to be terminated any and all existing activities, discussions or negotiations with any Persons conducted heretofore with respect to any offer or proposal that constitutes, or may reasonably be expected to lead to, an Acquisition Proposal, (ii) request the prompt return or destruction of all confidential information previously furnished to any Person (other than Simmons, Simmons Bank and their Representatives) that has made or indicated an intention to make an Acquisition Proposal, (iii) not waive or amend any “standstill” provision or provisions of similar effect to which it is a party or of which it is a beneficiary and shall strictly enforce any such provisions.

| 7.3 | Exchange Listing.

Simmons shall use its reasonable best efforts to list, prior to the Effective Time, on Nasdaq, subject to official notice of issuance, the shares of Simmons Common Stock to be issued to the holders of Triumph Common Stock pursuant to this Agreement, and Simmons shall give all notices and make all filings with Nasdaq required in connection with the transactions contemplated herein.

| 7.4 | Consents of Regulatory Authorities.

(a) The Parties and their respective Subsidiaries shall cooperate with each other and use their respective reasonable best efforts to prepare all documentation, to effect all applications, notices, petitions, and filings and to obtain all Permits and Consents of all third parties and Regulatory Authorities that are necessary or advisable to consummate the transactions contemplated by this Agreement (including the Merger), and to comply with the terms and conditions of all such Permits and Consents. Each of the Parties shall use its respective reasonable best efforts to resolve objections, if any, which may be asserted with respect to this Agreement or the transactions contemplated hereby by any Regulatory Authority or under any applicable Law or Order. Notwithstanding the foregoing, in no event shall any Simmons Entities be required, and the Triumph Entities shall not be permitted (without Simmons’s prior written consent in its sole discretion), to take any action, or commit to take any action, or to accept any restriction or condition, involving the Simmons Entities or the Triumph Entities, which is materially burdensome on Simmons’s or Simmons Bank’s business or on the business of Triumph or Triumph Bank, in each case following the Closing, or which would likely reduce the economic benefits of the transactions contemplated by this Agreement to Simmons to such a degree that Simmons would not have entered into this Agreement had such condition or restriction been known to it at the date hereof (any such condition or restriction, a “Burdensome Condition”).

(b) Each of the Parties shall have the right to review in advance, and to the extent practicable each will consult with the other, in each case subject to applicable Laws relating to the exchange of information, with

B-42

respect to, all material written information submitted to any third party or Regulatory Authority in connection with the transactions contemplated by this Agreement; provided, that Triumph shall not have the right to review portions of material filed by Simmons or Simmons Bank with a Regulatory Authority that contain competitively sensitive business or other proprietary information or confidential supervisory information. In exercising the foregoing rights, each of the Parties agrees to act reasonably and as promptly as practicable. Each Party agrees that it will consult with the other Party with respect to the obtaining of all Permits and Consents of third parties and Regulatory Authorities necessary or advisable to consummate the transactions contemplated by this Agreement and each Party will keep the other Party apprised of the status of material matters relating to completion of the transactions contemplated hereby, including advising the other Party upon receiving any communication from a Regulatory Authority the Consent of which is required for the consummation of the Merger and the other transactions contemplated by this Agreement that causes such Party to believe that there is a reasonable likelihood that any Requisite Regulatory Approval will not be obtained or that the receipt of such Requisite Regulatory Approval may be materially delayed. Subject to Section 10.15, except for non-material routine communications between counsel and a Regulatory Authority relating to the regulatory approval process or status, each Party shall consult with the other in advance of any meeting or conference with any Regulatory Authority in connection with the transactions contemplated by this Agreement.

(c) Each Party agrees, upon request, subject to Section 10.15 and applicable Laws, to promptly furnish the other Party with all information concerning itself, its Subsidiaries, directors, officers and shareholders and such other matters as may be reasonably necessary or advisable in connection with the Registration Statement, Proxy/Prospectus or any other statement, filing, notice or application made by or on behalf of Simmons, Triumph or any of their respective Subsidiaries to any third party and/or Regulatory Authority in connection with the transactions contemplated by this Agreement.

| 7.5 | Access to Information; Confidentiality and Notification of Certain Matters.

(a) Triumph shall promptly advise Simmons of any fact, change, event, effect, condition, occurrence, development or circumstance (i) that has had or would reasonably be expected to have, either individually or in the aggregate, a Material Adverse Effect on Triumph or (ii) which Triumph believes would or would be reasonably likely to cause or constitute a material breach of any of its representations, warranties, covenants or agreements contained herein or that reasonably could be expected to give rise, individually or in the aggregate, to the failure of a condition in ARTICLE 8; provided, that any failure to give notice in accordance with the foregoing with respect to any breach shall not be deemed to constitute a violation of this Section 7.5(a) or the failure of any condition set forth in Section 8.2 or 8.3 to be satisfied, or otherwise constitute a breach of this Agreement by the Party failing to give such notice, in each case unless the underlying breach would independently result in a failure of the conditions set forth in Section 8.2 or 8.3 to be satisfied; and provided, further, that the delivery of any notice pursuant to this Section 7.5(a) shall not cure any breach of, or noncompliance with, any other provision of this Agreement or limit the remedies available to Simmons.

(b) Prior to the Effective Time, Triumph shall permit the Representatives of Simmons to make or cause to be made such investigation of the business, Assets, information technology systems, Contracts, Books and Records, and personnel and such other information of it and its Subsidiaries and of their respective financial and legal conditions as Simmons reasonably requests and furnish to Simmons promptly all other information concerning its business, Assets, information technology systems, Contracts, Books and Records, and personnel and such other information as Simmons may reasonably request, provided that such investigation or requests shall not interfere unnecessarily with normal operations of Triumph. No investigation by Simmons shall affect or be deemed to modify or waive the representations, warranties, covenants and agreements of Triumph in this Agreement, or the conditions of such Party’s obligation to consummate the transactions contemplated by this Agreement. Neither Simmons nor Triumph nor any of their respective Subsidiaries shall be required to provide access to or to disclose information where such access or disclosure would violate or prejudice the rights of Simmons’s or Triumph’s, as the case may be, customers, jeopardize the attorney-client privilege of the institution

B-43

in possession or control of such information (after giving due consideration to the existence of any common interest, joint defense or similar agreement between the Parties) or contravene any Law, fiduciary duty or binding Contract entered into prior to the date of this Agreement or to the extent that Triumph may impose any reasonable restrictions with respect to in-person access in light of the Pandemic or the Pandemic Measures, including the health and safety of its employees. The Parties will make appropriate substitute disclosure arrangements under circumstances in which the restrictions of the preceding sentence apply. Without limiting the foregoing, and for the avoidance of doubt, subject to applicable Law, Triumph shall permit the Representatives of Simmons and Simmons Bank to observe meetings of committees or similar groups established to review and approve potential Loans or similar matters.

(c) Each Party shall, and shall cause its Subsidiaries and Representatives to, hold and use any information obtained in connection with this Agreement and in pursuit of the transactions contemplated hereby in accordance with the terms of the Confidentiality and Nondisclosure Agreement, dated March 29, 2021, between Simmons and Triumph (the “Confidentiality Agreement”).

(d) Prior to the Effective Time, Triumph shall promptly notify Simmons of any material change in the normal course of its or its Subsidiaries’ business or in the operation of its or its Subsidiaries’ properties and, to the extent permitted by applicable Law, of any material Litigation (or communications indicating that the same may be contemplated), or the institution or the threat of a material Litigation involving Triumph or any other Triumph Entity.

| 7.6 | Press Releases.

The Parties shall consult with each other before issuing any press release or other public disclosure or communication (including communications to employees, agents and contractors) related to this Agreement or the transactions contemplated hereby and shall not issue such press release or other public disclosure without the prior written consent of the other Party (which consent shall not be unreasonably withheld, delayed or conditioned); provided, that nothing in this Section 7.6 shall be deemed to prohibit any Party from making any press release or other public disclosure as may upon the advice of the Party’s outside counsel be required by Law or the rules or regulations of any United States or non-United States securities exchange, in which case the Party required to make the release or disclosure shall use its reasonable best efforts to allow the other Party reasonable time to comment on such release or disclosure in advance of the issuance thereof. The Parties have agreed upon the form of a joint press release announcing the execution of this Agreement.

| 7.7 | Tax Treatment.

(a) Each of the Parties intends, and undertakes and agrees to use its respective reasonable best efforts to cause, the Merger, and to take no action which would cause the Merger not, to qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code for federal income Tax purposes, and none of the Parties shall take any action that would cause the Merger to not so qualify. The Parties shall cooperate and use their reasonable best efforts in order to obtain the Tax Opinion. The Parties adopt this Agreement as a “plan of reorganization” within the meaning of Treasury Regulations Section 1.368-2(g) and for purposes of Sections 354, 361 and 368 of the Internal Revenue Code.

(b) Each of the Parties shall use its respective reasonable best efforts to cause their appropriate officers to execute and deliver to Covington certificates containing appropriate representations and covenants, reasonably satisfactory in form and substance to Covington, at such time or times as may be reasonably requested by Covington, including as of the effective date of the Proxy Statement/Prospectus and the Closing Date, in connection with such counsel’s deliveries of opinions with respect to the Tax treatment of the Merger.

B-44

(c) Unless otherwise required pursuant to a “determination” within the meaning of Section 1313(a) of the Internal Revenue Code, each Party shall report the Merger as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code and shall not take any inconsistent position therewith in any Tax Return.

(d) Prior to Closing, Triumph shall (i) deliver to Simmons and mail to the IRS in accordance with Treasury Regulation Section 1.897-2(h) (1) a statement, in form and substance satisfactory to Simmons, certifying that every Triumph Entity is not, and has not been during the applicable period specified in Section 897(c)(1)(A)(ii) of the Internal Revenue Code, a “United States real property holding company” within the meaning of Section 897(c)(2) of the Internal Revenue Code, which statement shall satisfy the requirements of Treasury Regulations Sections 1.897-2(h) and 1.1445-2(c)(3), together with (2) a notice prepared and executed in accordance with Treasury Regulations Section 1.897-2(h) to the IRS; and (ii) together therewith, furnish to Simmons proof of mailing the items described in subclause (i).

| 7.8 | Employee Benefits and Contracts.

(a) For a period of one year following the Effective Time, except as contemplated by this Agreement, any Simmons Entity shall provide generally to employees who are actively employed by a Triumph Entity on the Closing Date (“Covered Employees”) while employed by such Simmons Entity following the Closing Date employee benefits under Simmons Benefit Plans, on terms and conditions which are, in the aggregate, substantially comparable to those provided by Simmons Entities to their similarly situated employees; provided, that in no event shall any Covered Employee be eligible to participate in any closed or frozen plan of any Simmons Entity. Until such time as Simmons shall cause the Covered Employees to participate in the applicable Simmons Benefit Plans, the continued participation of the Covered Employees in the Triumph Benefit Plans shall be deemed to satisfy the foregoing provisions of this clause (it being understood that participation in Simmons Benefit Plans may commence at different times with respect to each of Simmons Benefit Plans). For purposes of determining eligibility to participate and vesting under Simmons Benefit Plans, and for purposes of determining a Covered Employee’s entitlement to paid time off under the applicable Simmons Entity’s paid time off program, the service of the Covered Employees with a Triumph Entity prior to the Effective Time shall be treated as service with a Simmons Entity participating in such Simmons Benefit Plans, to the same extent that such service was formally recognized by the Triumph Entities for purposes of a similar benefit plan; provided, that such recognition of service shall not (i) operate to duplicate any benefits of a Covered Employee with respect to the same period of service or (ii) apply for purposes of any plan, program or arrangement (x) under which similarly-situated employees of Simmons Entities do not receive credit for prior service, (y) that is grandfathered or frozen, either with respect to level of benefits or participation, or (z) for purposes of retiree medical benefits or level of benefits under a defined benefit pension plan.

(b) Prior to the Closing Date, the Triumph Entities shall take all necessary action (including without limitation the adoption of resolutions and plan amendments and the delivery of any required notices) to terminate, effective as of no later than the day before the Closing Date, any Triumph Benefit Plan that is intended to constitute a tax-qualified defined contribution plan under Internal Revenue Code Section 401(k) (a “401(k) Plan”). Triumph shall provide Simmons with a copy of the resolutions, plan amendments, notices and other documents prepared to effectuate the termination of the 401(k) Plans in advance and give Simmons a reasonable opportunity to comment on such documents (which comments shall be considered in good faith), and prior to the Closing Date, Triumph shall provide Simmons with the final documentation evidencing that the 401(k) Plans have been terminated.

(c) Upon request by Simmons in writing prior to the Closing Date, the Triumph Entities shall cooperate in good faith with Simmons prior to the Closing Date to amend, freeze, terminate or modify any other Triumph Benefit Plan to the extent and in the manner determined by Simmons effective upon the Closing Date (or at such different time mutually agreed to by the Parties) and consistent with applicable Law. Triumph

B-45

shall provide Simmons with a copy of the resolutions, plan amendments, notices and other documents prepared to effectuate the actions contemplated by this Section 7.8(c), as applicable, and give Triumph a reasonable opportunity to comment on such documents (which comments shall be considered in good faith), and prior to the Closing Date, Triumph shall provide Simmons with the final documentation evidencing that the actions contemplated herein have been effectuated.

(d) Without limiting the generality of Section 10.4, nothing in this Agreement, expressed or implied, is intended to confer upon any Person (other than the Parties or their respective successors), including any current or former employee, officer, director or consultant of Triumph or any of its Subsidiaries or Affiliates, any rights, remedies, obligations, or liabilities under or by reason of this Agreement. In no event shall the terms of this Agreement: (i) establish, amend, or modify any Triumph Benefit Plan or any “employee benefit plan” as defined in Section 3(3) of ERISA, or any other benefit plan, program, agreement or arrangement maintained or sponsored by Simmons, Triumph or any of their respective Affiliates; (ii) alter or limit the ability of the Surviving Corporation, Simmons or any of their Subsidiaries or Affiliates to amend, modify or terminate any Triumph Benefit Plan, employment agreement or any other benefit or employment plan, program, agreement or arrangement after the Closing Date; or (iii) confer upon any current or former employee, officer, director or consultant of Triumph or any of its Subsidiaries or Affiliates, any right to employment or continued employment or continued service with Simmons or any Simmons Subsidiaries, the Surviving Corporation or the Triumph Entities, or constitute or create an employment agreement with any employee, or interfere with or restrict in any way the rights of the Surviving Corporation, Triumph, Simmons or any Subsidiary or Affiliate thereof to discharge or terminate the services of any employee, officer, director or consultant of Triumph or any of its Subsidiaries or Affiliates at any time for any reason whatsoever, with or without cause.

(e) On the Closing Date, Triumph shall provide Simmons with a list of employees who have suffered an “employment loss” (as defined in the WARN Act) in the 90 days preceding the Closing Date or had a reduction in hours of a least 50% in the 180 days preceding the Closing Date, each identified by date of employment loss or reduction in hours, employing entity and facility location.

| 7.9 | Indemnification.

(a) For a period of six years after the Effective Time, the Surviving Corporation shall indemnify, defend and hold harmless the present and former directors or officers of the Triumph Entities (each, an “Indemnified Party”), against all Liabilities incurred in connection with any Litigation arising out of or pertaining to, the fact that such person is or was a director or officer of the Triumph Entities or, at Triumph’s request, of another corporation, partnership, joint venture, trust or other enterprise and pertaining to matters, acts or omissions existing or occurring at or prior to the Effective Time (including matters, acts or omissions occurring in connection with the approval of this Agreement and the transactions contemplated by this Agreement) (each a “Claim”), whether asserted or claimed prior to, at or after the Effective Time, to the fullest extent permitted under Triumph’s charter and bylaws as in effect as of the date of this Agreement (subject to applicable Law), including provisions relating to advances of expenses incurred in the defense of any Litigation; provided, that the Indemnified Party to whom expenses are advanced provides a written undertaking to repay such advances if it is ultimately determined that such Indemnified Party is not entitled to indemnification.

(b) The Surviving Corporation shall use its reasonable best efforts (and Triumph shall cooperate prior to the Effective Time in these efforts) to maintain in effect for a period of six years after the Effective Time Triumph’s existing directors’ and officers’ liability insurance policy (provided that the Surviving Corporation may substitute therefor (i) policies of at least the same coverage and amounts containing terms and conditions which are substantially no less advantageous to the insured or (ii) with the consent of Triumph given prior to the Effective Time, any other policy) with respect to claims arising from facts or events which occurred prior to the Effective Time; provided, that the Surviving Corporation shall not be obligated to make aggregate premium

B-46

payments for such six-year period in respect of such policy (or coverage replacing such policy) which exceed, for the portion related to Triumph’s directors and officers, 200% of the annual premium payments currently paid on Triumph’s current policy in effect as of the date of this Agreement (the “Maximum Amount”). If the amount of the premiums necessary to maintain or procure such insurance coverage exceeds the Maximum Amount, the Surviving Corporation shall use its reasonable best efforts to maintain the most advantageous policies of directors’ and officers’ liability insurance obtainable for a premium equal to the Maximum Amount. In lieu of the foregoing, Simmons, or Triumph in consultation with Simmons, may obtain on or prior to the Effective Time, a six-year “tail” prepaid policy providing equivalent coverage to that described in this Section 7.9(b) at a premium not to exceed the Maximum Amount. If the premium necessary to purchase such “tail” prepaid policy exceeds the Maximum Amount, Simmons or Triumph in consultation with Simmons may purchase the most advantageous “tail” prepaid policy obtainable for a premium equal to the Maximum Amount, and in each case, Simmons and the Surviving Corporation shall have no further obligations under this Section 7.9(b) other than to maintain such “tail” prepaid policy.

(c) Any Indemnified Party wishing to claim indemnification under Section 7.9(a), upon learning of any such Claim, shall promptly notify the Surviving Corporation thereof. In the event of any such Claim (whether arising before or after the Effective Time): (i) Simmons or the Surviving Corporation shall have the right to assume the defense thereof and Simmons and the Surviving Corporation shall not be liable to such Indemnified Parties for any legal expenses of other counsel or any other expenses subsequently incurred by such Indemnified Parties in connection with the defense thereof, except that if Simmons or the Surviving Corporation elects not to assume such defense or independent legal counsel for the Indemnified Parties advises that there are substantive issues which raise conflicts of interest between Simmons or the Surviving Corporation and the Indemnified Parties, the Indemnified Parties may retain counsel satisfactory to them, and Simmons or the Surviving Corporation shall pay all reasonable fees and expenses of such counsel for the Indemnified Parties as required under, and in accordance with, Triumph’s charter and bylaws as in effect as of the date of this Agreement (subject to applicable Law); provided, that Simmons or the Surviving Corporation shall be obligated pursuant to this Section 7.9(c) to pay for only one firm of counsel for all Indemnified Parties; (ii) the Indemnified Parties will cooperate in the defense of any such Claim; and (iii) Simmons and the Surviving Corporation shall not be liable for any settlement effected without its prior written consent; and provided, further, that Simmons and the Surviving Corporation shall not have any obligation hereunder to any Indemnified Party when and if a court of competent jurisdiction shall determine, and such determination shall have become final, that the indemnification of such Indemnified Party in the manner contemplated hereby is prohibited by applicable Law or not required by Triumph’s charter and bylaws as in effect as of the date of this Agreement (subject to applicable Law).

(d) If the Surviving Corporation or any successors or assigns shall consolidate with or merge into any other Person and shall not be the continuing or surviving Person of such consolidation or merger or if the Surviving Corporation (or any successors or assigns) shall transfer all or substantially all of its Assets to any Person, then and in each case, proper provision shall be made so that the successors and assigns of the Surviving Corporation shall assume the obligations set forth in this Section 7.9.

(e) The provisions of this Section 7.9 are intended to be for the benefit of and shall be enforceable by, each Indemnified Party and their respective heirs and Representatives.

(f) Notwithstanding anything in this Section 7.9 to the contrary, no indemnification payments will be made to an Indemnified Party with respect to an administrative proceeding or civil action initiated by any federal banking agency unless all of the following conditions are met: (i) the Simmons’s board of directors determines in writing that the Indemnified Party acted in good faith and in the best interests of Triumph or Triumph Bank; (ii) the Simmons’s board of directors determines that the payment will not materially affect the Simmons’s or Simmons Bank’s safety and soundness; (iii) the payment does not fall within the definition of a prohibited indemnification payment under 12 C.F.R. Part 359; and (iv) the Indemnified Party agrees in writing to

B-47

reimburse Simmons, to the extent not covered by permissible insurance, for payments made in the event that the administrative or civil action instituted by a banking Regulatory Authority results in a final order or settlement in which the Indemnified Party is assessed a civil money penalty, is prohibited from banking, or is required to cease an action or perform an affirmative action.

| 7.10 | Triumph Operating Functions.

Triumph and Triumph Bank shall cooperate with Simmons and Simmons Bank in connection with planning for the efficient and orderly combination of the Parties and the operation of the Surviving Corporation and the Surviving Bank, and in preparing for the consolidation of appropriate operating functions to be effective at the Effective Time or such later date as Simmons may decide. Each Party shall cooperate with the other Party in preparing to execute after the Effective Time conversion or consolidation of systems and business operations generally (including by entering into customary confidentiality, nondisclosure and similar agreements with such service providers or the other Party). Prior to Effective Time, each Party shall exercise, consistent with terms and conditions of this Agreement, complete control and supervision over its and its Subsidiaries’ respective operations.

| 7.11 | Shareholder Litigation.

Each of Triumph and Simmons shall promptly notify each other in writing of any action, arbitration, audit, hearing, investigation, litigation, suit, subpoena or summons issued, commenced, brought, conducted or heard by or before, or otherwise involving, any Regulatory Authority or arbitrator pending or, to the Knowledge of Triumph or Simmons, as applicable, threatened against Triumph, Simmons or any of their respective Subsidiaries or Representatives that (a) questions or would reasonably be expected to question the validity of this Agreement or the other agreements contemplated hereby or thereby or any actions taken or to be taken by Triumph, Simmons or their respective Subsidiaries with respect hereto or thereto or (b) seeks to enjoin or otherwise restrain the transactions contemplated hereby or thereby. Triumph shall give Simmons prompt notice of any shareholder litigation against Triumph or its directors or officers relating to the transactions contemplated by this Agreement and shall give Simmons every opportunity to participate in the defense or settlement of such litigation, provided that no such settlement shall be agreed to by any Triumph Entity without Simmons’s prior written consent (such consent not to be unreasonably withheld, delayed or conditioned).

| 7.12 | Legal Conditions to Merger; Additional Agreements.

Subject to Sections 7.1 and 7.4 of this Agreement, each of Triumph and Simmons shall, and shall cause its Subsidiaries to, use their reasonable best efforts (a) to take, or cause to be taken, all actions necessary, proper or advisable to comply promptly with all legal and regulatory requirements that may be imposed on such Party or its Subsidiaries with respect to the Merger and Bank Merger and, subject to the conditions set forth in ARTICLE 8 hereof, to consummate the transactions contemplated by this Agreement, and (b) to obtain (and to cooperate with the other Party to obtain) any Permit or Consent by, any Regulatory Authority and any other third party that is required to be obtained by Triumph or Simmons or any of their respective Subsidiaries in connection with, or to effect, the Merger, the Bank Merger, and the other transactions contemplated by this Agreement. In case at any time after the Effective Time any further action is necessary or desirable to carry out the purposes of this Agreement (including, any merger between a Subsidiary of Simmons, on the one hand, and a Subsidiary of Triumph, on the other hand) or to vest the Surviving Corporation and the Surviving Bank with full title to all Assets, rights, Consents, Permits, immunities and franchises of any of the Parties to the Merger and Bank Merger, the proper officers and directors of each Party and their respective Subsidiaries shall take all such necessary action as may be reasonably requested by Simmons.

B-48

| 7.13 | Closing Financial Statements.

At least eight Business Days prior to the Effective Time, Triumph shall provide Simmons with Triumph’s consolidated financial statements presenting the financial condition of Triumph and its Subsidiaries as of the close of business on the last day of the last month ended prior to the Effective Time and Triumph’s consolidated results of operations, cash flows, and shareholders’ equity for the period from January 1, 2021, through the close of business on the last day of the last month ended prior to the Effective Time (the “Closing Financial Statements”); provided, that if the Effective Time occurs on or before the 15th Business Day of the month, Triumph shall have provided consolidated financial statements as of and through the second month preceding the Effective Time. Such Closing Financial Statements shall have been prepared in accordance with GAAP and regulatory accounting principles and other applicable legal and accounting requirements, and reflect all period-end accruals and other adjustments. Such Closing Financial Statements shall also reflect as of their date (a) accruals for all fees, costs and expenses incurred or expected to be incurred (whether or not doing so is in accordance with GAAP) in connection (directly or indirectly) with the transactions contemplated by this Agreement, (b) the capital ratios set forth in Section 8.2(f), and (c) the asset quality metrics set forth in Section 8.2(d) and shall be accompanied by a certificate of Triumph’s chief financial officer, dated as of the date of such delivery of the Closing Financial Statements, to the effect that such financial statements meet the requirements of this Section 7.13 and continue to reflect accurately, as of the date of such certificate, the consolidated financial condition, results of operations, cash flows and shareholders’ equity of Triumph in all material respects (which certification shall be reaffirmed in the certificates required to be delivered pursuant to Section 8.2(c)).

| 7.14 | Dividends.

After the date of this Agreement, each of Simmons and Triumph shall coordinate with the other regarding the declaration of any dividends in respect of Simmons Common Stock and (to the extent permitted by this Agreement) Triumph Common Stock and the record dates and payment dates relating thereto, it being the intention of the Parties that, Holders of Triumph Common Stock shall not receive two or more dividends, or fail to receive one dividend, attributable to any particular quarter with respect to their shares of Triumph Common Stock and any shares of Simmons Common Stock any such Holder receives in exchange therefor in the Merger.

| 7.15 | Change of Method.

(b) by either Party, by written notice to the other Party, in the event (i) (A) any Regulatory Authority has denied a Requisite Regulatory Approval and such denial has become final, or has advised any Party that it will not grant (or intends to rescind or revoke if previously approved) a Requisite Regulatory Approval or (B) any Regulatory Authority shall have requested that Simmons, Triumph or any of their respective Affiliates withdraw (other than for technical reasons), and not be permitted to resubmit within 60 days, any application with respect to a Requisite Regulatory Approval, unless in each case the failure to obtain the Requisite Regulatory Approval shall be due to the failure of the Party seeking to terminate this Agreement to perform or observe the obligations, covenants and agreements of such Party set forth herein, (ii) subject to the terminating Party’s compliance with Section 7.16, the shareholders of Triumph fail to vote their approval of the matters relating to this Agreement and the transactions contemplated hereby at Triumph’s Shareholders’ Meeting where such matters were presented to such shareholders for approval and voted upon (taking into account any adjournment or postponement thereof as required by this Agreement), or (iii) any Law or Order permanently restraining, enjoining or otherwise prohibiting the consummation of the transactions contemplated by this Agreement shall have become final and nonappealable, provided that the Party seeking to terminate this Agreement pursuant to this Section 9.1(b)(iii) shall have used its reasonable best efforts to contest, appeal and remove such Law or Order;

(c) by either Party, by written notice to the other Party, in the event that the Merger shall not have been consummated by March 1, 2022 if the failure to consummate the transactions contemplated hereby on or before such date is not caused by any breach of this Agreement by the Party electing to terminate pursuant to this Section 9.1(c);

(d) by Simmons, by written notice to Triumph, in the event that the board of directors of Triumph has (i) failed to make the Triumph Recommendation or otherwise effected a Change in the Triumph Recommendation, (ii) breached the terms of Section 7.2 in any respect adverse to Simmons, or (iii) breached its obligations under Section 7.1 by failing to call, give notice of, convene or hold Triumph’s Shareholders’ Meeting in accordance with Section 7.1;

(e) by either Party, by written notice to the other Party (provided that the terminating Party is not then in material breach of any representation, warranty, covenant or other agreement contained herein), if there shall have been a breach of any of the covenants or agreements or any of the representations or warranties (or any such representation or warranty shall cease to be true) set forth in this Agreement on the part of Triumph, in the case of a termination by Simmons, or Simmons, in the case of a termination by Triumph, which breach or failure to be true, either individually or in the aggregate with all other breaches by such Party (or failures of such representations or warranties to be true), would constitute, if occurring or continuing on the Closing Date, the failure of a condition set forth in Section 8.2, in the case of a termination by Simmons, or Section 8.3, in the case of a termination by Triumph, and which is not cured within 45 days following written notice to Triumph, in the case of a termination by Simmons, or Simmons, in the case of a termination by Triumph, or by its nature or timing cannot be cured during such period (or such fewer days as remain prior to the date specified in Section 9.1(c));

(f) by Simmons, by written notice to Triumph, if any Regulatory Authority has granted a Requisite Regulatory Approval but such Requisite Regulatory Approval contains, or shall have resulted in or would reasonably be expected to result in, the imposition of a Burdensome Condition; or

(g) By Triumph, if the board of directors of Triumph so determines by a vote of at least two-thirds of the members of the entire board of directors of Triumph at any time during the five-day period commencing with the Determination Date, if both of the following conditions are satisfied:

| (i) | the Average Closing Price is less than $24.85; and

| (ii) | the difference between (A) the quotient obtained by dividing (1) the average of the closing prices of the Nasdaq Bank Index (as reported in The Wall Street Journal or, if not reported thereby, another alternative source as chosen by Simmons) for the 20 consecutive full trading days ending on and including the Determination Date by (2) $4,489.83 and (B) the quotient obtained by dividing (1) the Average Closing Price by (2) $31.07, is greater than 0.20 (or 20%),

subject, however, to the following three sentences. If Triumph elects to terminate this Agreement pursuant to this Section 9.1(g), it shall give written notice to Simmons (provided that such notice of termination may be withdrawn at any time within the aforementioned five-day period). During the five-day period commencing with its receipt of such notice, Simmons shall have the option to, in its sole and absolute discretion, elect to increase the Aggregate Cash Consideration by an amount in cash so that, as a result of such adjustment, the sum of (i) the Aggregate Cash Consideration and (ii) the Stock Consideration multiplied by the Average Closing Price shall be no less than the Minimum Merger Consideration. If Simmons so elects within such five-day period, it shall give prompt written notice to Triumph of such election and the revised Aggregate Cash Consideration, whereupon no termination shall have occurred pursuant to this Section 9.1(g) and this Agreement shall remain in effect in accordance with its terms (except as the Aggregate Cash Consideration shall have been so modified). “Minimum Merger Consideration” shall be the sum of (i) the product of (x) $24.85 and (y) the Stock Consideration and (ii) the Aggregate Cash Consideration.

| 10.10 | Counterparts; Signatures.

This Agreement may be executed in two or more counterparts, each of which shall be deemed to be an original, but all of which together shall constitute one and the same instrument. This Agreement and any signed agreement or instrument entered into in connection with this Agreement, and any amendments or waivers hereto or thereto, to the extent signed and delivered by means of a facsimile machine or by email delivery of a “.pdf” format data file, shall be treated in all manner and respects as an original agreement or instrument and shall be

B-71

considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. No Party or to any such agreement or instrument shall raise the use of a facsimile machine or e-mail delivery of a “.pdf” format data file to deliver a signature to this Agreement or any amendment or waiver hereto or any agreement or instrument entered into in connection with this Agreement or the fact that any signature or agreement or instrument was transmitted or communicated through the use of a facsimile machine or e-mail delivery of a “.pdf” format data file as a defense to the formation of a contract and each Party forever waives any such defense.

| 10.11 | Captions; Articles and Sections.

| 10.13 | Enforcement of Agreement.

The Parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement was not performed in accordance with its specific terms or was otherwise breached and that money damages would be both incalculable and an insufficient remedy for any breach of this Agreement. It is accordingly agreed that the Parties shall be entitled, without the requirement of posting bond, to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any court of the United States or any state having jurisdiction, this being in addition to any other remedy to which they are entitled at law or in equity.

| 10.14 | Severability.

Any term or provision of this Agreement which is invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement or affecting the validity or enforceability of any of the terms or provisions of this Agreement in any other jurisdiction. If any provision of this Agreement is so broad as to be unenforceable, the provision shall be interpreted to be only so broad as is enforceable.

| 10.15 | Confidential Supervisory Information.

Notwithstanding any other provision of this Agreement, no disclosure, representation or warranty shall be made (or other action taken) pursuant to this Agreement that would involve the disclosure of confidential supervisory information as defined in 12 C.F.R. § 261.2(b) of a Regulatory Authority by any Party to the extent prohibited by applicable Law.

(b) Each party hereto agrees that it will bring any action or proceeding in respect of any claim arising out of or related to this Agreement or the transactions contemplated hereby exclusively in any federal or state court of competent jurisdiction located in the State of Arkansas (the “Chosen Courts”), and, solely in connection with claims arising under this Agreement or the transactions that are the subject of this Agreement, (i) irrevocably submits to the exclusive jurisdiction of the Chosen Courts, (ii) waives any objection to laying venue in any such action or proceeding in the Chosen Courts, (iii) waives any objection that the Chosen Courts are an inconvenient forum or do not have jurisdiction over any party, and (iv) agrees that service of process upon such party in any such action or proceeding will be effective if notice is given in accordance with Section 5.3.

(c) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY SUIT, ACTION OR OTHER PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS

C-9

AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT.

5.9. Enforcement of Agreement. The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement was not performed in accordance with its specific terms or was otherwise breached and that money damages would be both incalculable and an insufficient remedy for any breach of this Agreement. It is accordingly agreed that the parties hereto shall be entitled, without the requirement of posting bond, to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any court of the United States or any state having jurisdiction, this being in addition to any other remedy to which they are entitled at law or in equity.

5.10. Severability. Any term or provision of this Agreement which is invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement or affecting the validity or enforceability of any of the terms or provisions of this Agreement in any other jurisdiction. If any provision of this Agreement is so broad as to be unenforceable, the provision shall be interpreted to be only so broad as is enforceable.

5.11. Assignment. Except as expressly contemplated hereby, neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any party hereto (whether by operation of Law or otherwise) without the prior written consent of the other parties hereto. Any purported assignment in contravention hereof shall be null and void. Subject to the preceding sentences, this Agreement will be binding upon, inure to the benefit of and be enforceable by the parties hereto and their respective successors and assigns.

5.12. No Third Party Beneficiaries. Nothing in this Agreement (including the documents and instruments referred to herein) expressed or implied, is intended to confer upon any Person, other than the parties hereto or their respective successors, any rights, remedies, obligations, or liabilities under or by reason of this Agreement. The representations and warranties in this Agreement are the product of negotiations among the parties hereto and are for the sole benefit of the parties hereto. Any inaccuracies in such representations and warranties are subject to waiver by the parties hereto in accordance herewith without notice or liability to any other Person. In some instances, the representations and warranties in this Agreement may represent an allocation among the parties hereto of risks associated with particular matters regardless of the knowledge of any of the parties hereto. Consequently, Persons other than the parties hereto may not rely upon the representations and warranties in this Agreement as characterizations of actual facts or circumstances as of the date of this Agreement or as of any other date. Notwithstanding any other provision hereof to the contrary, no Consent, approval or agreement of any third party beneficiary will be required to amend, modify to waive any provision of this Agreement.

5.13. [Individual Capacity. The Individual is signing this Agreement solely in his or her capacity as a Beneficial Owner of Nile Common Stock, and nothing herein shall prohibit, prevent or preclude the Individual from taking or not taking any action in the Individual’s capacity as an [officer][director] of Nile to the extent permitted by the Merger Agreement.]

(a) The parties hereto agree that this Agreement shall be governed by and construed in all respects in accordance with the Laws of the State of Arkansas without regard to any conflict of Laws or choice of Law principles that might otherwise refer construction or interpretation of this Agreement to the substantive Law of another jurisdiction.

D-9

(b) Each party hereto agrees that it will bring any action or proceeding in respect of any claim arising out of or related to this Agreement or the transactions contemplated hereby exclusively in any federal or state court of competent jurisdiction located in the State of Arkansas (the “Chosen Courts”), and, solely in connection with claims arising under this Agreement or the transactions that are the subject of this Agreement, (i) irrevocably submits to the exclusive jurisdiction of the Chosen Courts, (ii) waives any objection to laying venue in any such action or proceeding in the Chosen Courts, (iii) waives any objection that the Chosen Courts are an inconvenient forum or do not have jurisdiction over any party, and (iv) agrees that service of process upon such party in any such action or proceeding will be effective if notice is given in accordance with Section 5.3.

(c) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY SUIT, ACTION OR OTHER PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT: (I) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF ANY ACTION, SUIT OR PROCEEDING, SEEK TO ENFORCE THE FOREGOING WAIVER, (II) EACH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (III) EACH PARTY MAKES THIS WAIVER VOLUNTARILY, AND (IV) EACH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 5.7.

5.9. Enforcement of Agreement. The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement was not performed in accordance with its specific terms or was otherwise breached and that money damages would be both incalculable and an insufficient remedy for any breach of this Agreement.

Each of the parties hereto waives any defense in any action for specific performance that a remedy at law would be adequate.

5.10. Severability. Any term or provision of this Agreement which is invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement or affecting the validity or enforceability of any of the terms or provisions of this Agreement in any other jurisdiction. If any provision of this Agreement is so broad as to be unenforceable, the provision shall be interpreted to be only so broad as is enforceable.

Members of the Board:

You have requested our opinion as to the fairness, from a financial point of view, to the shareholders of Landmark Community Bank (“Landmark” or the “Company”) of the Merger Consideration (as defined below) to be received by the shareholders of the Company in the proposed merger transaction (the “Transaction”) with Simmons First National Corporation (“SFNC”) whereby pursuant to the Agreement and Plan of Merger to be dated June 4, 2021 (“the Agreement”), SFNC will acquire all of the issued and outstanding shares of common stock of Landmark. At the Effective Time, Company shall be merged with and into Simmons Bank (“Buyer Bank”) with Buyer Bank as the surviving bank in the Transaction. Capitalized terms used herein without definition have the meanings assigned to them in the Agreement.

“Nile Common Stock” means the no par value common stock of Landmark Community Bank.

We understand that each share of Nile Common Stock issued and outstanding immediately prior to the Effective Time (excluding the Canceled Shares and Nile Dissenting Shares), subject to Section 2.3(b), shall be converted into the right to receive, without interest the Per Share Cash Consideration and the Per Share Stock Consideration.

“Merger Consideration” means the sum of (A) the Per Share Cash Consideration, (B) the Per Share Stock Consideration, (C) the Fractional Share Payment (if any), and (D) any dividends or distributions (if any) pursuant to Section 3.1(d).

“Per Share Cash Consideration” means the quotient obtained by dividing the Cash Consideration by the Nile Shares Outstanding.

“Per Share Stock Consideration” means the quotient obtained by dividing the Stock Consideration by the Nile Shares Outstanding.

“Stock Consideration” means 4,500,000 shares of Buyer Common Stock.

“Aggregate Cash Consideration” means cash in the amount of $7,000,000.

Notwithstanding anything herein to the contrary, if the Cash Consideration is less than $0.00, then the Aggregate Cash Consideration shall be increased such that the Cash Consideration equals $0.00. The amount by which the Aggregate Cash Consideration is increased shall be referred to as the “Aggregate Cash Increase.” If the Aggregate Cash Consideration is increased, then the Stock Consideration shall be decreased by the number

E-1

of shares of Buyer Common Stock equal to the quotient obtained by dividing the Aggregate Cash Increase by the Average Closing Price (for the avoidance of doubt, if the quotient includes a fractional share, the quotient shall be rounded up to the next whole share (for example, if the quotient is 1,000.34, the quotient shall be rounded up to 1,001)).

“Cash Consideration” means the Aggregate Cash Consideration less the Aggregate Stock Option Payout.

Olsen Palmer LLC is an investment banking firm that has acted as financial advisor to the Company in connection with the Transaction. Olsen Palmer LLC, as part of its investment banking services, is regularly engaged in the valuation of financial institutions and their securities in connection with mergers and acquisitions and other corporate transactions. We will receive a fee for our services pursuant to the terms of our engagement with the Company, a substantial portion of which is contingent upon consummation of the Transaction. We will also receive a fee for rendering this opinion. The Company has also agreed to indemnify us against certain liabilities arising out of our engagement.

Olsen Palmer LLC has not provided investment banking and financial advisory services to the Company or SFNC during the two-year period prior to the date hereof, except with respect to the Transaction. Olsen Palmer LLC may provide investment banking, financial advisory and other financial services to the Company and/or SFNC in the future, for which Olsen Palmer LLC may receive compensation.

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

| (i) | a draft version of the Agreement dated May 31, 2021;

| (ii) | certain financial statements and other historical financial information of the Company and SFNC that we deemed relevant;

| (iii) | internal financial projections for the Company for the year ending December 31, 2021 and estimated long-term annual earnings and balance sheet growth rates for the years ending December 31, 2022, December 31, 2023, December 31, 2024, December 31, 2025, and December 31, 2026 as provided by the Company;

| (iv) | publicly available consensus analyst earnings per share estimates for SFNC for the years ending December 31, 2021, December 31, 2022, and December 31, 2023, as well as estimated dividends per share and long term earnings per share and asset growth rates for the years thereafter, as discussed with and confirmed by representatives of SFNC;

| (v) | a comparison of certain financial information for the Company with similar institutions for which publicly available information is available;

| (vi) | the financial terms of certain recent business combinations in the commercial banking industry, to the extent publicly available;

| (vii) | an analysis of the relative contribution that the Company and SFNC will make to the combined company;

| (viii) | an estimated range of the intrinsic value of the Company based on internal financial projections for the Company as provided by the Company;

| (ix) | the estimated pro forma financial impact of the merger on SFNC, based on assumptions relating to transaction expenses, acquisition accounting adjustments, and cost savings as communicated to Olsen Palmer LLC by representatives of SFNC;

We also discussed with certain members of senior management of the Company and its representatives the business, financial condition, results of operations and prospects of the Company. Olsen Palmer LLC had similar discussions with certain members of senior management of SFNC and its representatives regarding the business, financial condition, results of operations, and prospects of SFNC.

In performing our review, and for purposes of rendering our opinion, 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 the Company or SFNC or their representatives or that was otherwise reviewed by us and have assumed, without independent verification, such accuracy and completeness of all such information. We have further relied on the assurances of the management of the Company that they are not aware of any facts or circumstances that would make any of such information inaccurate or misleading. We have not been asked to and have not undertaken an independent verification of any of 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 appraisal of any assets, the collateral securing any assets or the liabilities (contingent or otherwise) of the Company or any of its subsidiaries and no such evaluation or appraisal was provided to us. We render no opinion or evaluation on the collectability of any assets or the future performance of any loans of the Company. We did not make an independent evaluation of the adequacy of the allowance for loan losses of the Company, or the combined entity after the Transaction and we have not reviewed any individual credit files relating to SFNC or the Company. We have assumed, with your consent, that the allowance for loan losses for both SFNC and the Company is adequate to cover such losses. We are not experts in the evaluation of allowances for loan and lease losses and have not independently verified such allowances or reviewed or examined any individual loan or credit files. We assumed, with your consent, that the respective allowances for loan and lease losses set forth in the financial statements of SFNC and the Company are adequate to cover such losses and comply fully with applicable law, regulatory policy and sound banking practices as of the date of such financial statements.

We have assumed in all respects material to our analysis that all of the representations and warranties contained in the Agreement and all related agreements are true and correct, that each party to the Agreement and all related agreements will perform, in all material respects, all of the covenants required to be performed by such party thereunder, that the conditions precedent in the Agreement are not waived and that the Transaction is lawful. We have also assumed that in the course of obtaining any necessary regulatory approvals for the consummation of the Transaction, no conditions will be imposed that will have a material adverse effect on the combined entity or contemplated benefits of the Transaction. In addition, we have relied upon and assumed, without independent verification, that the final form of the Agreement will not differ in any respect from the version of the Agreement identified above. Finally, with your consent, we have relied upon the advice the Company has received from its legal, accounting and tax advisors as to all legal, accounting and tax matters relating to the Transaction and the other transactions contemplated by the Agreement, and we have assumed that all such advice was correct.

Our opinion is necessarily based on financial, 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 could materially affect our opinion. We have not undertaken to update, revise, reaffirm or withdraw this opinion or otherwise comment upon events occurring after the date hereof.

Our opinion is directed solely to the Board of Directors of the Company (solely in its capacity as such) in connection with its consideration of the Transaction and may not be relied upon by any other person or entity (including, without limitation, security holders, creditors or other constituencies of the Company) or used for any other purpose without our prior written consent. This Opinion does not constitute a recommendation to the Board of Directors of the Company or to any shareholder of either the Company or SFNC as to how any such member of such board or any shareholder should vote at any meeting called to consider and vote upon the Transaction. We express no opinion as to the fairness of the Merger Consideration to the creditors or other constituencies of the Company. Our opinion is directed only to the fairness, from a financial point of view, of the Merger Consideration to the shareholders of the Company and does not address the underlying business decision of the Company to engage in the Transaction or the relative merits of the Transaction as compared to any other alternative business strategies that might exist for the Company. This opinion should not be construed as creating any fiduciary duty on the part of Olsen Palmer LLC to any party or person. This opinion shall not be disclosed, reproduced, disseminated, quoted, summarized or referred to at any time, in any manner or for any purpose, or used for any other purposes, without Olsen Palmer LLC’s prior written consent. This Opinion was not reviewed or issued by a fairness opinion committee. We have not been requested to opine as to, and this Opinion does not express an opinion as to or otherwise address, among other things: (i) the fairness of any portion or aspect of the Transaction to any one class or group of the Company’s or any other party’s security holders or other constituents vis-à-vis any other class or group of the Company’s or such other party’s security holders or other constituents (including, without limitation, the allocation of any consideration amongst or within such classes or groups of security holders or other constituents), or (ii) the fairness, financial or otherwise, of the amount, nature or any other aspect of any compensation to or consideration payable to or received by any officers, directors or employees of any party to the Transaction, any class of such persons or any other party, relative to the Merger Consideration or otherwise.

Based upon and subject to the foregoing, and in reliance thereon, it is our opinion that, as of the date hereof, the Merger Consideration to be received by the shareholders of the Company for all of the shares of the Nile Common Stock in the Transaction pursuant to the Agreement is fair, from a financial point of view, to such holders.

Very truly yours,

Board of Directors of Triumph Bancshares, Inc.

c/o Mr. Hilliard R. Crews, Jr., Chairman

5699 Poplar Avenue

Memphis, TN 38119

Board of Directors:

Southard Financial, LLC (“Southard Financial”) was retained by the Board of Directors (the “Board” or the “Client”) of Triumph Bancshares, Inc., a Tennessee corporation and bank holding company in connection with the merger of Triumph Bancshares, Inc. with Simmons First National Corporation. Triumph Bancshares, Inc. (“TBI”, the “Company”, or the “Seller”) is a party to an Agreement and Plan of Merger (the “Merger Agreement”) with Simmons First National Corporation (“SFNC” or the “Purchaser”). TBI will merge with and into SFNC (the “Merger” or the “Transaction”), with SFNC as the surviving corporation of the Merger. Simultaneously with the Merger, Triumph Bank (“Triumph” or the “Bank”) will be merged with and into Simmons Bank (“Simmons”), a subsidiary of the Purchaser. The Bank is domiciled in Memphis, Tennessee, while Simmons is domiciled in Pine Bluff, Arkansas.

Capitalized terms used herein without definition shall have the meanings assigned to them in the Merger Agreement. The terms and conditions of the Merger are more fully set forth in the Merger Agreement. You have requested our Opinion as to the fairness, from a financial point of view, of the consideration offered to holders of TBI common stock. Southard Financial, as part of its valuation advisory business, is regularly engaged in the valuation of financial institutions and their securities in connection with mergers and acquisitions and other corporate transactions.

Southard Financial reviewed the financial terms of the Merger. Under the terms of the Merger Agreement, holders of TBI common stock are entitled to receive, in exchange for all outstanding shares of TBI common stock, subject to adjustments outlined in the Merger Agreement, consideration equal to 4,164,839 shares of SFNC common stock. An additional cash payment of $2,645,938 (in the aggregate, rounded) will be made to optionholders of TBI. The aggregate implied deal value as of June 4, 2021 (date Merger Agreement was signed and as reported by S&P Global, Inc.) is shown below.

The Merger Agreement provides that if, as of the Determination Date, both of the following conditions are satisfied:

| (i) | the Average Closing Price is greater than $37.28; and

| (ii) | the difference between (A) the quotient obtained by dividing (1) the Average Closing Price by (2) $31.07 and (B) the quotient obtained by dividing (1) the average of the closing prices of the Nasdaq Bank Index (as reported in The Wall Street Journal or if not reported thereby, another alternative source as chosen by Buyer) for the 20 consecutive full trading days ending on and including the Determination Date by (2) $4,489.83, is greater than 0.20 (or 20%),

then the Stock Consideration shall be decreased by the number of whole shares of Buyer Common Stock so that, as a result of such adjustment, the sum of (i) the product obtained by multiplying the Stock Consideration by the Average Closing Price and (ii) the Aggregate Cash Consideration shall be no more than the Maximum Merger Consideration (defined as the sum of (i) the product of (x) $37.28 and (y) the Stock Consideration and (ii) the Aggregate Cash Consideration).

Further, the Merger Agreement may be terminated and the Merger abandoned at any time prior to the Effective Time by TBI, if the Board so determines by a vote of at least two-thirds of the members of the entire Board at any time during the five-day period commencing with the Determination Date, if both of the following conditions are satisfied:

| (i) | the Average Closing Price is less than $24.85; and

| (ii) | the difference between (A) the quotient obtained by dividing (1) the average of the closing prices of the Nasdaq Bank Index (as reported in The Wall Street Journal or if not reported thereby, another alternative source as chosen by Buyer) for the 20 consecutive full trading days ending on and including the Determination Date by (2) $4,489.83 and (B) the quotient obtained by dividing (1) the Average Closing Price by (2) $31.07, is greater than 0.20 (or 20%),

subject, however, to the following three sentences. If TBI elects to terminate the Merger Agreement, it shall give written notice to SFNC (provided that such notice of termination may be withdrawn at any time within the aforementioned five-day period). During the five-day period commencing with its receipt of such notice, SFNC shall have the option to, in its sole and absolute discretion, elect to increase the Aggregate Cash Consideration by an amount in cash so that, as a result of such adjustment, the sum of (i) the Aggregate Cash Consideration and (ii) the Stock Consideration multiplied by the Average Closing Price shall be no less than the Minimum Merger Consideration. If SFNC so elects within such five-day period, it shall give prompt written notice to TBI of such election and the revised Aggregate Cash Consideration, whereupon no termination shall have occurred and the Merger Agreement shall remain in effect in accordance with its terms (except as the Aggregate Cash Consideration shall have been so modified). Minimum Merger Consideration shall be the sum of (i) the product of (x) $24.85 and (y) the Stock Consideration and (ii) the Aggregate Cash Consideration.

In connection with rendering its Opinion, Southard Financial reviewed and considered, among other things:

| · | the Agreement and Plan of Merger dated June 4, 2021;

| · | certain publicly available financial statements and other historical financial information of TBI that Southard Financial deemed relevant;

| · | the publicly reported historical price and trading activity for SFNC common stock;

| · | a comparison of certain financial information for TBI with similar financial institutions for which information is publicly available;

| · | the financial terms of certain recent business combinations in the banking industry (on a regional and nationwide basis), to the extent publicly available;

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

| · | other information, financial studies, analyses and investigations, financial, economic, and market criteria as Southard Financial considered relevant.

Southard Financial also discussed with certain members of the management of TBI and its representatives the business, financial condition, results of operations, and prospects of TBI.

In performing its review, Southard Financial relied upon the accuracy and completeness of all of the financial and other information available to and reviewed by Southard Financial. Southard Financial assumed such accuracy and completeness to render its Opinion without any independent verification or investigation. Southard Financial relied on the assurances of the management that they were not aware of any facts or circumstances that would make any of such information inaccurate or misleading. Southard Financial was not asked to and did not undertake independent verification of any of such information. Southard Financial did not assume any responsibility or liability for the accuracy or completeness thereof. Southard Financial 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 TBI, nor was Southard Financial furnished with any such evaluations or appraisals. Southard Financial rendered no opinion or evaluation on the collectability of any assets or the future performance of any loans of TBI. Southard Financial did not independently evaluate the adequacy of the allowance for loan losses of TBI or the combined entity after the Merger. Southard Financial did not review any individual credit files relating to TBI. Southard Financial assumed that the allowances for loan loss provision at TBI were adequate to cover such losses and would be sufficient on a pro forma basis for the combined entity.

Southard Financial also assumed, with TBI’s consent, that (i) each of the parties to the Merger Agreement would comply in all material respects with all material terms of the Merger Agreement 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 required to be performed by such party under the 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 TBI, SFNC or the Merger or any related transactions, and (iii) the Merger and any related transactions would be consummated in accordance with the terms of the Merger 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 TBI’s consent, Southard Financial relied upon the advice that TBI 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 Merger Agreement. Accordingly, Southard Financial expressed no opinion as to any such matters.

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

In rendering its Opinion, Southard Financial performed a variety of financial analyses. The preparation of a fairness opinion is a complex process involving subjective judgments about the most appropriate and relevant financial analysis methods and applying those methods to particular circumstances. The process, therefore, is not necessarily susceptible to a partial analysis or summary description. Southard Financial 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 Southard Financial’s comparative analyses described below is identical to TBI, and no transaction is identical to the Merger. Accordingly, an analysis of comparable companies or transactions involves complex considerations and judgments concerning differences in financial and operating characteristics of the companies and other factors that could affect the public trading values or merger transaction values, as the case may be, of TBI and the companies to which they are being compared. In arriving at its Opinion, Southard Financial did not attribute any particular weight to any analysis or factor that it considered. Rather, Southard Financial made qualitative judgments as to the significance and relevance of each analysis and factor. Southard Financial 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; instead, Southard Financial made its determination as to the fairness of the Transaction based on its experience and professional judgment after considering the results of all its analyses taken as a whole.

In performing its analyses, Southard Financial also made numerous assumptions concerning industry performance, business and economic conditions, and various other matters, many of which are beyond the control of TBI. Southard Financial prepared its analyses solely for purposes of rendering its Opinion. Estimates of the values of companies do not purport to be appraisals or necessarily reflect the prices at which companies or their securities may actually be sold. Such estimates are inherently subject to uncertainty, and actual values may be materially different. Accordingly, Southard Financial’s analyses do not necessarily reflect the value of TBI common stock or the prices at which TBI common stock may be sold at any time. The analyses of Southard Financial and its Opinion were among many factors taken into consideration by TBI’s Board in making its determination to approve the Merger Agreement. The type and amount of consideration payable in the Merger were determined through negotiation between TBI and SFNC.

Our Opinion is directed to the Board of Directors of TBI in connection with its consideration of the Merger Agreement. Our Opinion does not constitute a recommendation to any shareholder of TBI as to how any such shareholder should vote at any meeting of shareholders called to consider and vote upon the approval of the Merger Agreement and the Merger. Our Opinion is directed only to the fairness, from a financial point of view, of the consideration paid to the holders of TBI common stock. It does not address the underlying business decision of TBI to engage in the Merger, the form or structure of the Merger or any other transactions contemplated in the Merger Agreement, the relative merits of the Merger as compared to any other alternative transactions or business strategies that might exist for TBI or the effect of any other transaction in which TBI 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 officer, director or employee of TBI, or any class of such persons, if any, relative to the compensation to be received in the Merger by any other shareholder.

(1) Consummation of a plan of merger to which the corporation is a party:

(A) If shareholder approval is required for the merger by § 48-21-104 or the charter and the shareholder is entitled to vote on the merger if the merger is submitted to a vote at a shareholders’ meeting or the shareholder is a nonconsenting shareholder under § 48-17-104(b) who would have been entitled to vote on the merger if the merger had been submitted to a vote at a shareholders’ meeting; or

G-1

(3) Consummation of a sale or exchange of all, or substantially all, of the property of the corporation other than in the usual and regular course of business, if the shareholder is entitled to vote on the sale or exchange if the sale or exchange is submitted to a vote at a shareholders’ meeting or the shareholder is a nonconsenting shareholder under § 48-17-104(b) who would have been entitled to vote on the sale or exchange if the sale or exchange had been submitted to a vote at a shareholders’ meeting, including a sale of all, or substantially all, of the property of the corporation in dissolution, but not including a sale pursuant to court order or a sale for cash pursuant to a plan by which all or substantially all of the net proceeds of the sale will be distributed to the shareholders within one (1) year after the date of sale;

(b) A shareholder entitled to dissent and obtain payment for the shareholder’s shares under this chapter may not challenge the corporate action creating the shareholder’s entitlement unless the action is unlawful or fraudulent with respect to the shareholder or the corporation.

(c) Notwithstanding subsection (a), no shareholder may dissent as to any shares of a security which, as of the date of the effectuation of the transaction which would otherwise give rise to dissenters’ rights, is listed on an exchange registered under § 6 of the Securities Exchange Act of 1934 (15 U.S.C. § 78f), as amended, or is a “national market system security,” as defined in rules promulgated pursuant to the Securities Exchange Act of 1934 (15 U.S.C. § 78a), as amended.

G-2

48-23-103. Dissent by nominees and beneficial owners.

(a) A record shareholder may assert dissenters’ rights as to fewer than all the shares registered in the record shareholder’s name only if the record shareholder dissents with respect to all shares beneficially owned by any one (1) person and notifies the corporation in writing of the name and address of each person on whose behalf the record shareholder asserts dissenters’ rights. The rights of a partial dissenter under this subsection (a) are determined as if the shares as to which the partial dissenter dissents and the partial dissenter’s other shares were registered in the names of different shareholders.

(b) A beneficial shareholder may assert dissenters’ rights as to shares of any one (1) or more classes held on the beneficial shareholder’s behalf only if the beneficial shareholder:

(1) Submits to the corporation the record shareholder’s written consent to the dissent not later than the time the beneficial shareholder asserts dissenters’ rights; and

(2) Does so with respect to all shares of the same class of which the person is the beneficial shareholder or over which the person has power to direct the vote.

48-23-201. Notice of dissenters’ rights.

(a) Where any corporate action specified in § 48-23-102(a) is to be submitted to a vote at a shareholders’ meeting, the meeting notice (including any meeting notice required under chapters 11-27 to be provided to nonvoting shareholders) must state that the corporation has concluded that the shareholders are, are not, or may be entitled to assert dissenters’ rights under this chapter. If the corporation concludes that dissenters’ rights are or may be available, a copy of this chapter must accompany the meeting notice sent to those record shareholders entitled to exercise dissenters’ rights.

(b) In a merger pursuant to § 48-21-105, the parent corporation must notify in writing all record shareholders of the subsidiary who are entitled to assert dissenters rights that the corporate action became effective. Such notice must be sent within ten (10) days after the corporate action became effective and include the materials described in § 48-23-203.

(c) Where any corporate action specified in § 48-23-102(a) is to be approved by written consent of the shareholders pursuant to § 48-17-104(a) or § 48-17-104(b):

(1) Written notice that dissenters’ rights are, are not, or may be available must be sent to each record shareholder from whom a consent is solicited at the time consent of such shareholder is first solicited and, if the corporation has concluded that dissenters’ rights are or may be available, must be accompanied by a copy of this chapter; and

(2) Written notice that dissenters’ rights are, are not, or may be available must be delivered together with the notice to nonconsenting and nonvoting shareholders required by § 48-17-104(e) and (f), may include the materials described in § 48-23-203 and, if the corporation has concluded that dissenters’ rights are or may be available, must be accompanied by a copy of this chapter.

(d) A corporation’s failure to give notice pursuant to this section will not invalidate the corporate action.

G-3

48-23-202. Notice of intent to demand payment.

(a) If a corporate action specified in § 48-23-102(a) is submitted to a vote at a shareholders’ meeting, a shareholder who wishes to assert dissenters’ rights with respect to shares for which dissenters’ rights may be asserted under this chapter:

(1) Must deliver to the corporation, before the vote is taken, written notice of the shareholder’s intent to demand payment if the proposed action is effectuated; and

(2) Must not vote, or cause or permit to be voted, any such shares in favor of the proposed action.

(b) If a corporate action specified in § 48-23-102(a) is to be approved by less than unanimous written consent, a shareholder who wishes to assert dissenters’ rights with respect to shares for which dissenters’ rights may be asserted under this chapter must not sign a consent in favor of the proposed action with respect to such shares.

(c) A shareholder who fails to satisfy the requirements of subsection (a) or subsection (b) is not entitled to payment under this chapter.

48-23-203. Dissenters’ notice.

(a) If a corporate action requiring dissenters’ rights under § 48-23-102(a) becomes effective, the corporation must send a written dissenters’ notice and form required by subdivision (b)(1) to all shareholders who satisfy the requirements of § 48-23-202(a) or § 48-23-202(b). In the case of a merger under § 48-21-105, the parent must deliver a dissenters’ notice and form to all record shareholders who may be entitled to assert dissenters’ rights.

(b) The dissenters’ notice must be delivered no earlier than the date the corporate action specified in § 48-23-102(a) became effective, and no later than (10) days after such date, and must:

(1) Supply a form that:

(A) Specifies the first date of any announcement to shareholders made prior to the date the corporate action became effective of the principal terms of the proposed corporate action;

(B) If such announcement was made, requires the shareholder asserting dissenters’ rights to certify whether beneficial ownership of those shares for which dissenters’ rights are asserted was acquired before that date; and

(C) Requires the shareholder asserting dissenters’ rights to certify that such shareholder did not vote for or consent to the transaction;

G-4

(2) State:

(A) Where the form must be sent and where certificates for certificated shares must be deposited and the date by which those certificates must be deposited, which date may not be earlier than the date for receiving the required form under subdivision (b)(2)(B);

(B) A date by which the corporation must receive the form, which date may not be fewer than forty (40) nor more than sixty (60) days after the date the subsection (a) dissenters’ notice is sent, and state that the shareholder shall have waived the right to demand payment with respect to the shares unless the form is received by the corporation by such specified date;

(C) The corporation’s estimate of the fair value of shares; and

(D) That, if requested in writing, the corporation will provide, to the shareholder so requesting, within ten (10) days after the date specified in subdivision (b)(2)(B) the number of shareholders who return the forms by the specified date and the total number of shares owned by them; and

(3) Be accompanied by a copy of this chapter if the corporation has not previously sent a copy of this chapter to the shareholder pursuant to § 48-23-201.

48-23-204. Duty to demand payment.

(a) A shareholder sent a dissenters’ notice described in § 48-23-203 must demand payment, certify whether the shareholder acquired beneficial ownership of the shares before the date required to be set forth in the dissenters’ notice pursuant to § 48-23-203(b)(2), and deposit the shareholder’s certificates in accordance with the terms of the notice.

(b) The shareholder who demands payment and deposits the shareholder’s share certificates under subsection (a) retains all other rights of a shareholder until these rights are cancelled or modified by the effectuation of the proposed corporate action.

(c) A shareholder who does not demand payment or deposit the shareholder’s share certificates where required, each by the date set in the dissenters’ notice, is not entitled to payment for the shareholder’s shares under this chapter.

48-23-205. Share restrictions.

G-5

48-23-206. Payment.

(a) Except as provided in § 48-23-208, as soon as the proposed corporate action is effectuated, or upon receipt of a payment demand, whichever is later, the corporation shall pay each dissenter who complied with § 48-23-204 the amount the corporation estimates to be the fair value of each dissenter’s shares, plus accrued interest.

(b) The payment must be accompanied by:

(1) The corporation’s balance sheet as of the end of a fiscal year ending not more than sixteen (16) months before the date 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;

(2) A statement of the corporation’s estimate of the fair value of the shares, which estimate shall equal or exceed the corporation’s estimate given pursuant to § 48-23-203(b)(2)(C);

(3) An explanation of how the interest was calculated;

(4) A statement of the dissenter’s right to demand payment under § 48-23-209; and

(5) A copy of this chapter if the corporation has not previously sent a copy of this chapter to the shareholder pursuant to § 48-23-201 or § 48-23-203.

48-23-207. Failure to take action.

(a) If the corporation does not effectuate the proposed action that gave rise to the dissenters’ rights within two (2) months after the date set for demanding payment and depositing share certificates, the corporation shall return the deposited certificates and release the transfer restrictions imposed on uncertificated shares.

(b) If, after returning deposited certificates and releasing transfer restrictions, the corporation effectuates the proposed action, it must send a new dissenters’ notice under § 48-23-203 and repeat the payment demand procedure.

48-23-208. After-acquired shares.

(a) A corporation may elect to withhold payment required by § 48-23-206 from a dissenter unless the dissenter was the beneficial owner of the shares before the date set forth in the dissenters’ notice as the date of the first announcement to news media or to shareholders of the principal terms of the proposed corporate action.

(b) To the extent the corporation elects to withhold payment under subsection (a), after effectuating the proposed corporate action, it shall estimate the fair value of the shares, plus accrued interest, and shall pay this amount to each dissenter who agrees to accept it in full satisfaction of the dissenter’s demand. The corporation shall send with its offer a statement of its estimate of the fair value of the shares, an explanation of how the interest was calculated, and a statement of the dissenter’s right to demand payment under § 48-23-209.

G-6

48-23-209. Procedure if shareholder dissatisfied with payment or offer.

(a) A dissenter may notify the corporation in writing of the dissenter’s own estimate of the fair value of the dissenter’s shares and amount of interest due, and demand payment of the dissenter’s estimate (less any payment under § 48-23-206), or reject the corporation’s offer under § 48-23-208 and demand payment of the fair value of the dissenter’s shares and interest due, if:

(1) The dissenter believes that the amount paid under § 48-23-206 or offered under § 48-23-208 is less than the fair value of the dissenter’s shares or that the interest due is incorrectly calculated;

(2) The corporation fails to make payment under § 48-23-206 within two (2) months after the date set for demanding payment; or

(3) The corporation, having failed to effectuate the proposed action, does not return the deposited certificates or release the transfer restrictions imposed on uncertificated shares within two (2) months after the date set for demanding payment.

(b) A dissenter waives the dissenter’s right to demand payment under this section unless the dissenter notifies the corporation of the dissenter’s demand in writing under subsection (a) within one (1) month after the corporation made or offered payment for the dissenter’s shares.

48-23-301. Court action.

(a) If a demand for payment under § 48-23-209 remains unsettled, the corporation shall commence a proceeding within two (2) months after receiving the payment demand and petition the court to determine the fair value of the shares and accrued interest. If the corporation does not commence the proceeding within the two-month period, it shall pay each dissenter whose demand remains unsettled the amount demanded.

(b) The corporation shall commence the proceeding in a court of record having equity jurisdiction in the county where the corporation’s principal office (or, if none in this state, its registered office) is located. If the corporation is a foreign corporation without a registered office in this state, it shall commence the proceeding in the county in this state where the registered office of the domestic corporation merged with or whose shares were acquired by the foreign corporation was located.

(c) The corporation shall make all dissenters (whether or not residents of this state) whose demands remain unsettled, parties to the proceeding as in an action against their shares and all parties must be served with a copy of the petition. Nonresidents may be served by registered or certified mail or by publication as provided by law.

(d) The jurisdiction of the court in which the proceeding is commenced under subsection (b) is plenary and exclusive. The court may appoint one (1) or more persons as appraisers to receive evidence and recommend decision on the question of fair value. The appraisers have the powers described in the order appointing them, or in any amendment to it. The dissenters are entitled to the same discovery rights as parties in other civil proceedings.

(e) Each dissenter made a party to the proceeding is entitled to judgment:

(1) For the amount, if any, by which the court finds the fair value of the dissenter’s shares, plus accrued interest, exceeds the amount paid by the corporation; or

(2) For the fair value, plus accrued interest, of the dissenter’s after-acquired shares for which the corporation elected to withhold payment under § 48-23-208.

G-7

48-23-302. Court costs and counsel fees.

(a) The court in an appraisal proceeding commenced under § 48-23-301 shall determine all costs of the proceeding, including the reasonable compensation and expenses of appraisers appointed by the court. The court shall assess the costs against the corporation, except that the court may assess 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 § 48-23-209.

(b) The court may also assess the fees and expenses of counsel and experts for the respective parties, in amounts the court finds equitable against:

(1) The corporation and in favor of any or all dissenters if the court finds the corporation did not substantially comply with the requirements of part 2 of this chapter; or

(2) 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 chapter.

(c) If the court finds that the services of counsel 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 counsel reasonable fees to be paid out of the amounts awarded to the dissenters who were benefited.

G-8

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

| Item 20. | Indemnification of Directors and Officers.

Article Sixteenth of the Amended and Restated Articles of Incorporation, or the Articles of Incorporation, of Simmons First National Corporation, or Simmons, provides that Simmons’ directors will not be personally liable to Simmons or any of its shareholders for monetary damages resulting from breaches of their fiduciary duty as directors to the fullest extent permitted by the Arkansas Business Corporation Act of 1987, as amended, or the 1987 Act. The 1987 Act permits the limitation of liability for monetary damages of directors for breaches of fiduciary duty, except (a) for any breach of the director’s duty of loyalty to Simmons or its shareholders, (b) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (c) under Arkansas Code Annotated, or the ACA, Section 4-27-833, as the same exists or hereafter may be amended, (d) for any transaction from which the director derived an improper personal benefit, or (e) for any action, omission, transaction, or breach of a director’s duty creating any third party liability to any person or entity other than Simmons or shareholder.

ACA Section 4-27-850 permits a corporation, under specified circumstances, to indemnify its current and former directors, officers, employees or agents against expenses (including attorney’s fees), judgments, fines and amounts paid in settlements actually and reasonably incurred by them in connection with any action, suit or proceeding brought by third parties by reason of the fact that the directors, officers, employees or agents acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe their conduct was unlawful. In a derivative action, i.e., one by or in the right of the corporation, indemnification may be made only for expenses actually and reasonably incurred by directors, officers, employees or agents in connection with the defense or settlement of an action or suit, and only with respect to a matter as to which they shall have acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the corporation, except that no indemnification shall be made if such person shall have been adjudged liable to the corporation, unless and only to the extent that the court in which the action or suit was brought shall determine upon application that the defendant directors, officers, employees or agents are fairly and reasonably entitled to indemnity for such expenses despite such adjudication of liability.

Article Twelfth of the Articles of Incorporation provides that Simmons shall, to the full extent permitted by the 1987 Act, indemnify all persons whom it may indemnify pursuant thereto.

The effect of the indemnification provisions contained in the Articles of Incorporation is to require Simmons to indemnify its directors and officers under circumstances where such indemnification would otherwise be discretionary. The Articles of Incorporation specify that the indemnification rights granted thereunder are enforceable contract rights which are not exclusive of any other indemnification rights that the director or officer may have under any by-law, vote of shareholders or disinterested directors or otherwise. As permitted under Arkansas law, the Articles of Incorporation also authorize the purchase of directors’ and officers’ insurance for the benefit of its past and present directors and officers, irrespective of whether Simmons has the power to indemnify such persons under Arkansas law. Simmons currently maintains insurance as authorized by these provisions.

The Articles of Incorporation also provide that expenses incurred by a director or officer in defending a civil or criminal lawsuit or proceeding arising out of actions taken in his or her official capacity, or in certain other capacities, will be paid by Simmons in advance of the final disposition of the matter upon the approval of (i) Simmons’ board of directors by a majority vote of a quorum consisting of directors who are not parties to the proceeding, (ii) if such a quorum is not obtainable or, even if obtainable, if a quorum of disinterested directors so directs, then by independent legal counsel in a written opinion, or (iii) the shareholders, and upon receipt of an undertaking from the director or officer to repay the sum advanced if it is ultimately determined that he or she is not entitled to be indemnified by Simmons pursuant to applicable provisions of Arkansas law.

II-1

Simmons has also entered into an indemnification agreement with each of the directors and the executive officers of Simmons, which we refer to as the indemnitees. These indemnification agreements supplement the indemnification provisions contained in the Articles of Incorporation and generally provide that the Simmons shall indemnify the indemnitees to the fullest extent permitted by applicable law, subject to certain exceptions, against expenses, judgments, fines and other amounts actually and reasonably incurred in connection with their service as a director or officer and also provide for rights to advancement of expenses and contribution.

The indemnification provisions are not intended to deny or otherwise limit third-party or derivative suits against Simmons or its directors or officers. However, to the extent a director or officer were entitled to indemnification, the financial burden of a third-party suit would be borne by Simmons, and Simmons would not benefit from derivative recoveries since the amount of such recoveries would be repaid to the director or officer pursuant to the agreements.

Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended, or the Securities Act, may be permitted to directors, officers, or persons controlling the registrant pursuant to the foregoing provisions, the registrant has been informed that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

| (5) | 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 registrant 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.

| (6) | That every prospectus (1) that is filed pursuant to paragraph (5) above, or (2) that purports to meet the requirements of Section 10(a)(3) of the Securities 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 this registration statement and will not be used until such amendment is effective, and that for purposes of determining any liability under the Securities Act, 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.

| (7) | To respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11 or 13 of this form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

| (8) | To supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in this registration statement when it became effective.

| (9) | Insofar as indemnification for liabilities arising under the Securities Act 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 SEC such indemnification is against public policy as expressed in the Securities 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 Securities Act and will be governed by the final adjudication of such issue.
