The estimated number of shares of First Choice common stock outstanding at the effective time of the merger includes (a) 183,764 shares of First Choice common stock issuable upon vesting or settlement of First Choice restricted stock awards to acquire shares of First Choice common stock, and (b) 123,632 shares of First Choice common stock that may be issued to the holders of options to acquire shares of First Choice common stock.

PRELIMINARY JOINT PROXY STATEMENT/PROSPECTUS — SUBJECT TO COMPLETION — DATED MAY 18, 2021

MERGER PROPOSED — YOUR VOTE IS VERY IMPORTANT

Dear Stockholder of Enterprise:

On April 26, 2021, Enterprise Financial Services Corp, or Enterprise, and its wholly-owned subsidiary bank, Enterprise Bank & Trust, or EB&T, entered into an Agreement and Plan of Merger, which we refer to as the merger agreement, with First Choice Bancorp, or First Choice, and its wholly-owned subsidiary bank, First Choice Bank, or FCB, pursuant to which Enterprise will, on the terms and subject to the conditions set forth in the merger agreement, acquire First Choice in an all-stock transaction. Under the merger agreement, First Choice will merge with and into Enterprise, which we refer to as the merger, and FCB will subsequently merge with and into EB&T, with Enterprise and EB&T as the surviving entities.

We are requesting that you take certain actions as a holder of Enterprise common stock. In connection with the merger, Enterprise will hold a virtual special meeting of its stockholders, or the Enterprise special meeting. At the Enterprise special meeting, Enterprise will ask its stockholders to approve (i) the merger agreement and the merger, including the issuance of shares of Enterprise’s common stock, par value $0.01 per share, or Enterprise common stock, to holders of First Choice common stock, no par value per share, or First Choice common stock, pursuant to the merger agreement, or the Enterprise merger and share issuance proposal, (ii) an amendment to Enterprise’s certificate of incorporation to increase the number of authorized shares of Enterprise common stock from 45,000,000 shares to 75,000,000, or the Enterprise charter amendment proposal, and (iii) a proposal to adjourn or postpone the Enterprise special meeting, if necessary or appropriate, to solicit additional proxies in favor of the Enterprise merger and share issuance proposal and/or the Enterprise charter amendment proposal, or the Enterprise adjournment proposal. The Enterprise special meeting will be held in a virtual meeting format only. You will not be able to attend the Enterprise special meeting physically in-person. To participate in the meeting visit https://www. .

In the merger, holders of First Choice common stock will receive 0.6603 shares of Enterprise common stock, together with cash in lieu of a fractional share of Enterprise common stock, for each share of First Choice common stock they own, subject to potential adjustment as provided in the merger agreement. Holders of Enterprise common stock will continue to own their existing shares of Enterprise common stock. The shares of Enterprise common stock and the cash in lieu of fractional shares issuable in the merger is referred to as the stock consideration. We estimate that, following completion of the merger, existing Enterprise stockholders will own approximately 80% and former First Choice shareholders will own approximately 20% of the outstanding common stock of the combined company.

Enterprise’s common stock is listed for trading on the Nasdaq Global Select Market under the symbol “EFSC.” Based on the number of shares of First Choice common stock, stock options and restricted stock awards outstanding and the following closing prices of Enterprise’s common stock on the Nasdaq Global Select Market: (i) $50.15 on April 26, 2021, the last trading day before public announcement of the merger agreement and (ii) $ on , 2021, the latest practicable trading day before the date of this joint proxy statement/prospectus, the implied value of the stock consideration per share would be approximately $33.11 and $ , respectively, and the implied value of the aggregate stock consideration would be approximately $392 million and $ million, respectively. The implied value of the stock consideration will fluctuate as the market price of Enterprise’s common stock fluctuates. You should obtain current market quotations for Enterprise’s common stock.

Your vote is important regardless of the number of shares of Enterprise common stock that you own. Approval of the Enterprise merger and share issuance proposal requires the affirmative vote of the holders of at least a majority of the outstanding shares of Enterprise common stock entitled to vote on the Enterprise merger and share issuance proposal at the Enterprise special meeting. If you do not vote, it will have the same effect as voting “AGAINST” the Enterprise merger and share issuance proposal. Accordingly, whether or not you plan to attend the Enterprise special meeting, please take time to vote by following the voting instructions included in the enclosed proxy card to make sure that your shares are represented at the meeting. Submitting a proxy now will not prevent you from being able to vote electronically at the Enterprise special meeting.

QUESTIONS AND ANSWERS ABOUT THE MERGER

The following are answers to certain questions that you may have regarding the merger and the Enterprise and First Choice special meetings. We urge you to read carefully the remainder of this joint proxy statement/prospectus because the information in this section may not provide all the information that might be important to you in determining how to vote. Additional information is also contained in the appendices to this joint proxy statement/prospectus.

Q: Why am I receiving these materials?

A: Enterprise and First Choice have entered into the merger agreement, pursuant to which, among other things, Enterprise would acquire First Choice by merger. If the required Enterprise stockholder, First Choice shareholder and regulatory approvals are obtained and the merger is subsequently completed, First Choice will merge with and into Enterprise, with Enterprise surviving. Immediately after the merger is effective, First Choice’s wholly-owned bank subsidiary, FCB, will merge with and into EB&T, the wholly-owned bank subsidiary of Enterprise, with EB&T surviving.

If you are an Enterprise stockholder, you are being asked to vote to approve (i) the merger agreement and the merger, including the issuance of shares of Enterprise’s common stock to First Choice shareholders in accordance with the terms of the merger agreement (which we refer to as the Enterprise merger and share issuance proposal), (ii) an amendment to Enterprise’s certificate of incorporation to increase the number of authorized shares of Enterprise common stock from 45,000,000 shares to 75,000,000 (which we refer to as the Enterprise charter amendment proposal), and (iii) a proposal to adjourn the Enterprise special meeting to a later date or dates, if necessary, to permit further solicitation of proxies if there are not sufficient votes at the time of the Enterprise special meeting to approve the Enterprise merger and share issuance proposal (which we refer to as the Enterprise adjournment proposal).

If you are a First Choice shareholder, you are being asked to vote to approve (i) the merger agreement and the transactions contemplated thereby (which we refer to as the First Choice merger proposal), and (ii) to adjourn the First Choice special meeting to a later date or dates, if necessary, to permit further solicitation of proxies if there are not sufficient votes at the time of the First Choice special meeting to approve the merger proposal (which we refer to as the First Choice adjournment proposal).

The merger cannot be completed unless Enterprise’s stockholders approve the Enterprise merger and share issuance proposal and First Choice’s shareholders approve the First Choice merger proposal. Therefore, Enterprise and First Choice are holding the Enterprise and First Choice special meetings to vote on the Enterprise merger and share issuance proposal and the First Choice merger proposal, respectively. Information about the Enterprise and First Choice special meetings is contained in this joint proxy statement/prospectus. This joint proxy statement/prospectus contains important information about the merger, the merger agreement, a copy of which is included as Appendix A to this joint proxy statement/prospectus, and the Enterprise and First Choice proxy solicitations. You should read this information carefully and in its entirety.

This document serves as a proxy statement being used by the Enterprise board of directors to solicit proxies of Enterprise stockholders for use at the Enterprise special meeting and as a proxy statement being used by the First Choice board of directors to solicit proxies of First Choice shareholders for use at the First Choice special meeting. This document also serves as a prospectus of Enterprise being delivered to First Choice shareholders because Enterprise is offering to issue shares of its common stock to First Choice shareholders in connection with the merger, which we refer to as the Enterprise share issuance.

Q: What items of business will Enterprise stockholders and First Choice shareholders consider at the Enterprise special meeting and First Choice special meeting, respectively?

A: At the Enterprise special meeting, Enterprise stockholders will be asked to vote in favor of the Enterprise merger and share issuance proposal, the Enterprise charter amendment proposal and the Enterprise adjournment proposal. At the First Choice special meeting, First Choice shareholders will be asked to vote in favor of the First Choice merger proposal and the First Choice adjournment proposal.

TABLE OF CONTENTS

Q: What will First Choice shareholders receive in the merger?

A: If the Enterprise merger and share issuance proposal and the First Choice merger proposal are approved and the merger is completed, each share of First Choice common stock will be converted into the right to receive 0.6603 shares of Enterprise common stock, subject to potential adjustment as provided in the merger agreement. Each holder of shares of First Choice common stock exchanged pursuant to the merger who would otherwise have been entitled to receive a fractional share of Enterprise’s common stock (after taking into account all certificates and book-entry shares delivered by such holder) will receive, in lieu of a fractional share, an amount of cash (without interest and rounded to the nearest whole cent) determined by multiplying such fractional interest by the daily volume weighted average price of Enterprise’s common stock for the 20 consecutive trading days ending on the last trading day immediately preceding the closing date of the merger. See “The Merger Agreement — The Merger Consideration” beginning on page . We refer to the shares of Enterprise common stock issuable to First Choice shareholders upon the effective time of the merger, together with any cash payable in lieu of fractional shares of Enterprise common stock, collectively as the stock consideration.

Based on the number of shares of First Choice common stock, stock options and restricted stock awards outstanding and the following closing prices of Enterprise common stock on the Nasdaq Global Select Market: (i) $50.15 on April 26, 2021, the last trading day before public announcement of the merger agreement, and (ii) $ on , 2021, the latest practicable trading day before the date of this joint proxy statement/prospectus, the implied value of the stock consideration per share would be approximately $33.11 and $ , respectively, and the implied value of the aggregate stock consideration would be approximately $392 million and $ million, respectively.

Q: What will holders of First Choice options and other First Choice stock-based awards receive in the merger?

A: Immediately prior to the effective time of the merger:

•

each unvested First Choice option will vest or be forfeited, as the case may be, pursuant to the terms of the applicable First Choice benefit plan or award agreement;

•

each vested and outstanding First Choice option will be canceled and extinguished and exchanged for the right to receive (without interest) an amount of cash equal to the product of (i) the aggregate number of shares of First Choice common stock issuable upon exercise of each such First Choice option and (ii) the excess, if any, of (A) the daily volume weighted average price of Enterprise’s common stock for the 20 consecutive trading days ending on the last trading day immediately preceding the closing date of the merger multiplied by the exchange ratio over (B) the per-share exercise price of such First Choice option, less any applicable taxes required to be withheld with respect to such cash payment; and

•

each unvested or unsettled award of First Choice restricted stock awards will vest or be cancelled pursuant to the terms of the applicable First Choice stock plan or award agreement. Unless cancelled, the First Choice restricted stock awards will be exchanged for the stock consideration.

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

A: The value of Enterprise’s common stock will fluctuate between the date of this joint proxy statement/prospectus and the completion of the merger based upon the market value of Enterprise common stock. Any fluctuation in the market price of Enterprise common stock after the date of this joint proxy statement/prospectus will change the value of the stock consideration received by First Choice shareholders. The total value of the stock consideration issued to First Choice shareholders upon completion of the merger will fluctuate based on the share price of Enterprise common stock and the number of shares of First Choice common stock and restricted stock awards, other than First Choice options, outstanding on the date of the merger, and is subject to adjustment pursuant to the merger agreement.

TABLE OF CONTENTS

Q: Will First Choice shareholders be able to trade the Enterprise common stock that they receive in the merger?

A: Yes. The Enterprise common stock to be issued to First Choice shareholders will be listed on the Nasdaq Global Select Market under the symbol “EFSC.” Unless you are deemed an “affiliate” of Enterprise after the merger is completed, you may sell the shares of Enterprise common stock you receive without restriction.

Q: How do First Choice shareholders receive the stock consideration?

A: After the merger is completed, Enterprise’s exchange agent will mail each First Choice shareholder of record in a separate mailing (i) a letter of transmittal, which shall specify that delivery shall be effected, and risk of loss and title to your certificates and book-entry shares shall pass, only upon proper delivery of the certificates to the exchange agent or, in the case of book-entry shares, upon adherence to the procedures set forth in the letter of transmittal, and (ii) instructions for use in effecting the surrender of the certificates or, in the case of book-entry shares, the surrender of such shares, for payment of the stock consideration. Any portion of the stock consideration not claimed by a First Choice shareholder by surrender of his, her or its certificates or book-entry shares to the exchange agent prior to the first anniversary of the closing date of the merger will be delivered by the exchange agent to Enterprise. Any First Choice shareholder that has not complied with the instructions by the exchange agent shall thereafter only look to Enterprise for payment of the stock consideration (which includes any cash in lieu of fractional shares). You should not send in your certificates until you receive instructions to do so. See “The Merger Agreement — The Merger Consideration” beginning on page .

Q: What are the material U.S. federal income tax consequences of the merger to each First Choice shareholder?

A: The merger is intended to qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended, which we refer to as the Code, and it is a condition to completion of the merger that Enterprise and First Choice each receive a legal opinion to that effect. These opinions will not bind the Internal Revenue Service, or the IRS, which could take a different view. Assuming the merger qualifies as a reorganization, subject to the limitations and more detailed discussion set forth in “Material United States Federal Income Tax Considerations” beginning on page , a First Choice shareholder that is a U.S. holder generally will not recognize gain or loss on the exchange of First Choice common stock for Enterprise common stock in the merger, other than with respect to cash received in lieu of fractional shares of Enterprise common stock.

Tax matters are complicated, and the tax consequences of the merger to a particular First Choice shareholder will depend in part on such shareholder’s individual circumstances. Accordingly, each First Choice shareholder is urged to consult the shareholder’s own tax advisor for a full understanding of the tax consequences of the merger to such shareholder, including the applicability and effect of federal, state, local and foreign income and other tax laws.

Q: Do First Choice shareholders have rights to dissent from the merger?

A: No, First Choice shareholders will not be entitled to any statutory appraisal or dissenters’ rights in connection with the merger. Under the California General Corporation Law, or CGCL, shareholders are generally entitled to dissent from a merger or consolidation and, in certain circumstances, obtain payment of the fair value of their shares when a merger or consolidation occurs. However, the CGCL provides that appraisal rights are not available where the dissenting shares are listed on a national securities exchange and the merger consideration consists only of shares that are listed on a national securities exchange and cash in lieu of fractional shares. First Choice’s common stock is traded on the Nasdaq Capital Market, a national security exchange, and the merger consideration is comprised only of Enterprise’s common stock, which is traded on the Nasdaq Global Select Market, a national security exchange, and cash in lieu of fractional shares. See “The Merger — Appraisal or Dissenters’ Rights in the Merger,” beginning on page .

TABLE OF CONTENTS

Q: Are there regulatory or other conditions to the completion of the merger?

A: Yes. The mergers and related transactions require approval from or notice to the Federal Deposit Insurance Corporation, which we refer to as the FDIC, the Missouri Division of Finance, which we refer to as the MDOF, the Board of Governors of the Federal Reserve System and the Federal Reserve Bank of St. Louis, which we refer to collectively as the Federal Reserve, and the California Department of Financial Protection and Innovation, which we refer to as CDFPI. As of the date of this joint proxy statement/prospectus, Enterprise and First Choice have filed the necessary application with the FDIC, and applications with the Federal Reserve and MDOF are in process and will be filed following the date of this joint proxy statement/prospectus. Additionally, the approval of the Enterprise merger and share issuance proposal requires the affirmative vote of the holders of at least a majority of the outstanding shares of Enterprise common stock entitled to vote on the Enterprise merger and share issuance proposal at the Enterprise special meeting, and the First Choice merger proposal requires the affirmative vote of at least a majority of the outstanding shares of First Choice common stock entitled to vote on the First Choice merger proposal at the First Choice special meeting. Completion of the merger is also subject to other conditions specified in the merger agreement. See “The Merger Agreement — Conditions to Completion of the Merger,” beginning on page .

Q: What do the Enterprise and First Choice boards of directors recommend?

A: The Enterprise board of directors unanimously approved and adopted the merger agreement and the transactions contemplated thereby, and unanimously recommends that Enterprise stockholders vote “FOR” the Enterprise merger and share issuance proposal, “FOR” the Enterprise charter amendment proposal and “FOR” the Enterprise adjournment proposal.

The First Choice board of directors unanimously approved and adopted the merger agreement and the transactions contemplated thereby and unanimously recommends that First Choice shareholders vote “FOR” the First Choice merger proposal and “FOR” the First Choice adjournment proposal.

Q: Why is my vote important?

A: The merger cannot be completed unless the Enterprise stockholders approve the Enterprise merger and share issuance proposal and the First Choice shareholders approve the First Choice merger proposal. Information about the Enterprise and First Choice special meetings, the merger and other matters to be considered by Enterprise’s stockholders and First Choice’s shareholders is contained in this document.

All of the directors of First Choice have entered into voting agreements, which we refer to as the voting agreements, with Enterprise to, among other things, vote the shares of First Choice common stock owned by them in favor of the First Choice merger proposal and other matters required to be approved or adopted to effect the merger and any other transactions contemplated by the merger agreement. As of the close of business on 2021, the record date for the First Choice special meeting, First Choice directors beneficially owned, in the aggregate, approximately % of First Choice common stock. The voting agreements are substantially in the form attached to this joint proxy statement/prospectus as Appendix B.

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

A: Enterprise stockholders and First Choice shareholders may receive more than one set of voting materials, including multiple copies of this joint proxy statement/prospectus and multiple proxy cards or voting instruction cards. For example, if you hold shares of Enterprise or First Choice 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 Enterprise or First Choice common stock and your shares are registered in more than one name, you will receive more than one proxy card. Please complete, sign, date and return each proxy card and voting instruction card that you receive or otherwise follow the voting instructions set forth in this joint proxy statement/prospectus to ensure that you vote every share of Enterprise or First Choice common stock that you own.

TABLE OF CONTENTS

Q: What happens if I sell my shares of First Choice common stock before the First Choice special meeting?

A: The record date for determining which First Choice shareholders are eligible to vote at the First Choice special meeting is earlier than both the date of the First Choice special meeting and the completion of the merger. If you transfer your shares of First Choice common stock after the record date for the First Choice special meeting but before the First Choice special meeting you will, unless special arrangements are made, retain the right to vote the shares at the First Choice special meeting but will transfer the right to receive the stock consideration to the purchaser of the shares.

Q: Are there any risks that should be considered in deciding whether to vote for the matters required to be voted on by Enterprise stockholders or First Choice shareholders?

A: Yes. Set forth under the heading of “Risk Factors,” beginning on page 22, are a number of risk factors that Enterprise stockholders and First Choice shareholders should consider carefully.

Q: When do you expect the merger to be completed?

A: We expect to complete the merger shortly after all of the conditions to the merger are fulfilled, including obtaining the approval of Enterprise stockholders and First Choice shareholders and the approval of the applicable regulatory agencies. We anticipate this will occur in the third quarter of 2021; however, delays may occur. We cannot assure you that we will obtain the necessary shareholder approvals and regulatory approvals or that the other conditions precedent to the merger can or will be satisfied.

Q. How will my rights as a First Choice shareholder differ following the merger?

A: Upon completion of the merger, holders of First Choice common stock will become Enterprise stockholders and their rights as stockholders will be governed by Enterprise’s certificate of incorporation, as amended, and amended and restated bylaws, as well as the Delaware General Corporation Law, or DGCL. The rights associated with First Choice common stock are different from the rights associated with Enterprise common stock. See “Comparison of Stockholder and Shareholder Rights” beginning on page .

Q: What happens if the merger is not completed?

A: If the merger is not completed, holders of First Choice common stock will not receive any consideration for their shares in connection with the merger. Instead, First Choice will remain an independent company. In addition, if the merger agreement is terminated in certain circumstances, First Choice may be required to pay a termination fee in the amount of $16,800,000. If the merger agreement is terminated by either party as a result of the other party’s breaches of its representations, warranties or material breaches of its covenants set forth in the merger agreement, and such breach would result in the closing conditions not being satisfied, then the non-terminating party will be required to pay the terminating party $1,500,000 as liquidated damages. See “The Merger Agreement — Termination of the Merger Agreement” beginning on page .

Q: How many votes do Enterprise stockholders have?

A: Enterprise stockholders are entitled to one vote for each share of Enterprise common stock held as of the Enterprise record date. As of the close of business on the Enterprise record date, there were outstanding shares of Enterprise common stock.

Q: What constitutes a quorum for the Enterprise special meeting?

A: The Enterprise special meeting will conduct business only if a majority of the outstanding shares of Enterprise common stock is represented in person or by proxy at the Enterprise special meeting in order to constitute a quorum. If you submit valid proxy instructions or attend the Enterprise special meeting virtually, your shares will be counted to determine whether there is a quorum, even if you abstain from voting.

Q: What vote is required to approve each proposal at the Enterprise special meeting?

A: Proposal 1 — The Enterprise Merger and Share Issuance Proposal. Approval of the Enterprise merger and share issuance proposal requires the affirmative vote of the holders of at least a majority of the outstanding shares of Enterprise common stock entitled to vote on the Enterprise merger and share issuance proposal at the Enterprise special meeting. If you fail to submit a proxy or to vote electronically at the Enterprise special meeting, mark “ABSTAIN” on your proxy or fail to instruct your bank, broker or other nominee (which we refer to as a broker non-vote) with respect to the Enterprise merger and share issuance proposal, it will have the same effect as a vote “AGAINST” the Enterprise merger and share issuance proposal.

Proposal 2 — The Enterprise Charter Amendment Proposal. Approval of the Enterprise charter amendment proposal requires the affirmative vote of the holders of at least a majority of the outstanding shares of Enterprise common stock entitled to vote on the Enterprise charter amendment proposal at the Enterprise special meeting. If you fail to submit a proxy or to vote electronically at the Enterprise special meeting, mark “ABSTAIN” on your proxy or fail to instruct your bank, broker or other nominee (which we refer to as a broker non-vote) with respect to the Enterprise charter amendment proposal, it will have the same effect as a vote “AGAINST” the Enterprise charter amendment proposal.

Proposal 3 — The Enterprise Adjournment Proposal. Approval of the Enterprise adjournment proposal requires the affirmative vote of at least a majority of the shares of Enterprise common stock present in person or by proxy at the Enterprise special meeting, whether or not a quorum is present. If you fail to submit a proxy or to vote electronically at the Enterprise special meeting, or fail to instruct your bank, broker or other nominee (which we refer to as a broker non-vote) with respect to the Enterprise adjournment proposal, it will have no effect on such proposal. If you mark “ABSTAIN” on your proxy with respect to the Enterprise adjournment proposal, it will have the same effect as a vote “AGAINST” the Enterprise adjournment proposal.

Q: If my shares of Enterprise common stock are held in street name by my broker, will my broker automatically vote my shares for me?

A: No. Your bank, broker or other nominee will not be able to vote shares held by it in street name on your behalf without instructions from you. You should instruct your bank, broker or other nominee to vote your shares by following the directions your bank, broker or other nominee provides to you.

TABLE OF CONTENTS

Q: What if I abstain from voting, fail to vote or fail to instruct my bank, broker or other nominee?

A: A broker non-vote occurs when a bank, broker, trustee or other nominee is not permitted to vote on a “non-routine” matter without instructions from the beneficial owner of the shares and the beneficial owner fails to provide the bank, broker, trustee or other nominee with such instructions. Broker non-votes only count toward a quorum if at least one proposal is presented with respect to which the bank, broker, trustee or other nominee has discretionary authority. It is expected that all proposals to be voted on at the Enterprise special meeting will be “non-routine” matters, and, as such, broker non-votes, if any, will not be counted as present and entitled to vote for purposes of determining a quorum at the Enterprise special meeting. If your bank, broker, trustee or other nominee holds your shares of Enterprise common stock in “street name,” such entity will vote your shares of Enterprise 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, trustee or other nominee with this joint proxy statement/prospectus.

With respect to the Enterprise merger and share issuance proposal and the Enterprise charter amendment proposal, if you fail to submit a proxy or vote electronically at the Enterprise special meeting, mark “ABSTAIN” on your proxy or fail to instruct your bank, broker or other nominee with respect to the Enterprise merger and share issuance proposal or the Enterprise charter amendment proposal, it will have the same effect as a vote “AGAINST” the Enterprise merger and share issuance proposal and/or the Enterprise charter amendment proposal.

With respect to the Enterprise adjournment proposal, if you fail to submit a proxy or to vote electronically at the Enterprise special meeting, or fail to instruct your bank, broker or other nominee (which we refer to as a broker non-vote) with respect to the Enterprise adjournment proposal, it will have no effect on such proposal. If you mark “ABSTAIN” on your proxy with respect to the Enterprise adjournment proposal, it will have the same effect as a vote “AGAINST” the Enterprise adjournment proposal.

Q: Can I attend the virtual Enterprise special meeting and vote my shares?

A: Yes. While not required to, all Enterprise stockholders are invited to attend the virtual Enterprise special meeting. Stockholders of record can vote electronically at the virtual Enterprise special meeting. If your shares are registered directly in your name with our stock transfer agent, Computershare, you are considered a stockholder of record and the beneficial owner of those shares. As a stockholder of record, you have the right to grant your voting proxy directly to Enterprise, or to vote electronically at the virtual Enterprise special meeting. You may submit your proxy by mail, by logging onto the Internet website specified on your proxy card or by calling the toll free number listed on your proxy card.

If your shares are held in a stock brokerage account or by a bank, you are still considered the beneficial owner of those shares, but your shares are said to be held in “street name.” Generally, only stockholders of record may vote electronically at the virtual Enterprise special meeting. If your shares are held in “street name,” you will receive a form from your broker or bank seeking instruction as to how your shares should be voted. Many of our stockholders who hold their shares in “street name” through a nominee have the option to submit their proxies or voting instructions to their nominee electronically by telephone or the Internet. These stockholders should review and follow the voting instructions provided by their nominee, including any instructions related to revoking your voting instructions. You are also invited to attend the virtual Enterprise special meeting. However, since you are not the stockholder of record, you may not vote your shares electronically at the virtual Enterprise special meeting unless you obtain a legal proxy from your broker or bank.

Q: Can I change my vote after I have mailed my signed proxy card?

A: Yes. There are five ways for Enterprise stockholders to revoke their proxy and change their vote. Enterprise stockholders that hold shares in their name as a stockholder of record as of the Enterprise record date may change their vote or revoke any proxy at any time before the Enterprise special meeting is called to order by (i) delivering a written notice of revocation to Enterprise, (ii) completing, signing and returning a new proxy card with a later date than such stockholder’s original proxy card prior to such time that the proxy card for any such stockholder must be received, and any earlier proxy will be revoked automatically, (iii) logging onto the Internet website specified on such stockholder’s proxy card in the same manner such

First Choice Shareholders Will Receive Shares of Enterprise Common Stock and Cash in Lieu of Fractional Shares for Each Share of First Choice Common Stock Exchanged in the Merger (Page )

At the effective time of the merger, each share of First Choice common stock outstanding will, by virtue of the merger and without any action on the part of First Choice shareholders, be converted into the right to receive 0.6603 shares of Enterprise common stock, subject to potential adjustment as provided in the merger agreement, and First Choice shareholders will no longer be owners of First Choice common stock. The value of the stock consideration to be issued to First Choice shareholders in connection with the merger will fluctuate between the date of this joint proxy statement/prospectus and the completion of the merger as the market price of Enterprise’s common stock fluctuates. Based on the number of shares of First Choice common stock, stock options and restricted stock awards outstanding and the following closing prices of Enterprise’s common stock on the Nasdaq Global Select Market: (i) $50.15 on April 26, 2021, the last trading day before public announcement of the merger agreement; and (ii) $ on , 2021, the latest practicable trading day before the date of this joint proxy statement/prospectus; the implied value of the stock consideration per share would be approximately $33.11 and $ , respectively, and the implied value of the aggregate stock consideration would be approximately $392 million and $ million, respectively. No fractional shares of Enterprise common stock will be issued in connection with the merger, and holders of First Choice common stock will be entitled to receive cash in lieu thereof.

Treatment of Outstanding First Choice Options (Page )

At the effective time of the merger, each unvested First Choice option that is outstanding immediately prior to the effective time of the merger will vest or be forfeited pursuant to the terms of the applicable First Choice benefit plan or award agreement. Each vested First Choice option that is outstanding at the effective time of the merger will be canceled and extinguished in exchange for the right to receive a single lump sum cash payment equal to the product of (i) the aggregate number of shares of First Choice common stock issuable upon exercise of each such First Choice option and (ii) the excess, if any, of (A) the daily volume weighted average price of Enterprise’s common stock for the 20 consecutive trading days ending on the last trading day immediately preceding the closing date of the merger multiplied by the exchange ratio over (B) the per-share exercise price of such First Choice option, less any applicable taxes required to be withheld with respect to such cash payment. If the exercise price per share of any such First Choice option is equal to or greater than the Enterprise average share price multiplied by the exchange ratio, the First Choice option will be canceled without any cash payment being made in respect thereof. For First Choice options that are exercised before the closing, the underlying shares of First Choice common stock received upon exercise will be exchanged for the stock consideration.

Assuming no First Choice options are exercised before the closing, cash payments to holders of First Choice options would amount to approximately $ in the aggregate based on the closing price of Enterprise common stock as of , 2021.

Certain Directors and Executive Officers May Have Interests in the Merger That Differ from Your Interests (Page )

Certain directors and executive officers of First Choice and/or FCB have interests in the merger other than their interests as First Choice shareholders, including:

•

Pursuant to the terms of certain employment agreements and change in control agreements, and upon the termination of certain compensation plans under the terms of the merger agreement, First Choice and/or FCB directors, officers and employees may become entitled to change in control, severance, or other payments, including acceleration of deferred compensation, upon the occurrence of the merger.

•

To the extent a director or executive officer of First Choice and/or FCB holds any vested and outstanding options at the effective time of the merger, the First Choice options will be canceled and extinguished in exchange for the right to receive a single lump sum cash payment. To the extent a director or executive officer of First Choice and/or FCB holds any unvested or unsettled awards of First Choice restricted stock awards, such restricted stock awards will vest or be cancelled pursuant to the terms of the applicable First Choice stock plan or award agreement. Unless cancelled, the First Choice restricted stock awards will be exchanged for the stock consideration.

The selected First Choice director must be independent with respect to Enterprise for purposes of Nasdaq’s listing requirements and mutually agreeable to Enterprise and First Choice. Enterprise and First Choice have determined that Peter Hui, the Chairman of the Board of First Choice and FCB, will be appointed to the Enterprise board, with such appointment to be effective as of the effective time of the merger. Mr. Hui will serve until the first annual meeting of the stockholders of Enterprise following the effective time of the merger and until he or his successor is elected and qualified.

We Have Agreed When and How First Choice Can Consider Third-Party Acquisition Proposals (Page )

We have agreed that First Choice will not, and will cause its subsidiaries and its and its subsidiaries’ representatives, agents, advisors and affiliates not to, solicit or knowingly encourage any inquiry, offer or proposal that constitutes, or could reasonably be expected to lead to, a proposal to acquire First Choice or FCB, except as permitted by the merger agreement. In addition, we have agreed that First Choice will not engage in negotiations with or provide confidential information to a third party regarding acquiring First Choice or FCB, except as permitted by the merger agreement. However, if First Choice receives an unsolicited acquisition proposal from a third party, First Choice can participate in negotiations with and provide

TABLE OF CONTENTS

confidential information to the third party if, among other steps, the First Choice board of directors concludes in good faith that the proposal is superior to the Enterprise merger proposal and that the failure to take such actions would breach or reasonably be expected to result in a breach of its fiduciary duties. First Choice’s receipt of a superior proposal or participation in such negotiations gives First Choice the right to terminate the merger agreement in certain circumstances.

We Must Meet Several Conditions to Complete the Merger (Page )

We May Terminate the Merger Agreement (Page )

We can mutually agree at any time to terminate the merger agreement without completing the merger, even if Enterprise has received approval of the Enterprise merger and share issuance proposal by its stockholders and/or First Choice has received approval of the First Choice merger proposal by its shareholders. Also, either of us can decide, without the consent of the other, to terminate the merger agreement in certain circumstances, including:

TABLE OF CONTENTS

•

if (i) there is a final non-appealable denial of a required regulatory approval or an application for a required regulatory approval has been withdrawn upon the request of the applicable governmental authority, (ii) any required regulatory approval includes any of the conditions described in the fourth bullet point under “— We Must Meet Several Conditions to Complete the Merger” in this summary above, or (iii) any court of competent jurisdiction or other governmental authority issues a final, non-appealable order, decree, ruling or takes other action restraining, enjoining or otherwise prohibiting the transactions contemplated by the merger agreement; provided, however, that no party has a right to terminate the merger agreement if such denial is due to the failure of the party seeking to terminate the merger agreement to perform or observe the covenants set forth in the merger agreement;

•

if the Enterprise stockholders fail to approve the Enterprise merger and share issuance proposal at the Enterprise special meeting, so long as, in the case of Enterprise seeking to terminate, Enterprise had not breached any of its obligations in the merger agreement related to the Enterprise special meeting;

•

if the First Choice shareholders fail to approve the First Choice merger proposal at the First Choice special meeting, so long as, in the case of First Choice seeking to terminate, First Choice had not breached any of its obligations in the merger agreement related to the First Choice special meeting;

•

if the terminating party is not then in breach of any representation or warranty, covenant, or agreement contained in the merger agreement, in the event of a breach by the other party of any of its representations or warranties in the merger agreement that (i) cannot be or has not been cured within 30 days’ written notice to the breaching party, or 60 days if such breach cannot reasonably be cured within 30 days and such cure is able to be cured within 60 days and is being diligently pursued, and (ii) would entitle the non-breaching party not to consummate the merger under the merger agreement;

•

if the terminating party is not then in material breach of any representation, warranty, covenant, or agreement contained in the merger agreement, in the event of a material breach by the other party of any of its covenants or agreements in the merger agreement that (i) cannot be or has not been cured within 30 days’ written notice to the breaching party, or 60 days if such breach cannot reasonably be cured within 30 days and such cure is able to be cured with the 60 days and is being diligently pursued, and (ii) would entitle the non-breaching party not to consummate the merger under the merger agreement; or

•

if the merger is not completed on or before December 31, 2021, provided that if additional time is necessary to obtain the requisite regulatory approvals, this date may be automatically extended by three months.

In addition, Enterprise may terminate the merger agreement if:

•

First Choice has materially breached its covenants described under “The Merger Agreement — No Solicitation” beginning on page and such breach is not cured on or before the expiration of the fifth business day after the occurrence of such breach; or

•

the First Choice board withdraws, modifies or fails to affirm its recommendation that First Choice shareholders approve the merger agreement and the transactions contemplated by the merger agreement or recommends an acquisition proposal other than the merger, as more specifically described under “The Merger Agreement — First Choice Board’s Covenant to Recommend the Merger Agreement” beginning on page .

In addition, First Choice may terminate the merger agreement:

•

if: (i) the Enterprise daily volume weighted average stock price for the 20 consecutive trading days ending on the trading day immediately preceding the fifth trading day prior to the closing of the merger, which is referred to as the triggering VWAP, is less than $39.704 per share; and (ii) the triggering VWAP underperforms the average closing price of a specified index of financial institution stocks during the 20 trading days ending on the trading day immediately preceding the fifth trading day prior to the closing of the merger by more than 20%. If First Choice elects to terminate the merger agreement in such instance, Enterprise may elect to reinstate the merger by adjusting the exchange

TABLE OF CONTENTS

ratio to increase the stock consideration, in which case no termination will occur and the merger agreement will remain in effect according to its terms (except the stock consideration, which will have been adjusted); or

•

at any time prior to obtaining the requisite First Choice shareholder approval, if the First Choice board or a First Choice board committee makes a subsequent determination with respect to a superior proposal, provided that First Choice has complied with its obligations described under “The Merger Agreement — No Solicitation” beginning on page .

Termination Fee and Liquidated Damages (Page )

First Choice must pay Enterprise a termination fee of $16,800,000 if the merger agreement is terminated under specified circumstances.

In addition, if the merger agreement is terminated by either party as a result of the other party’s breach of its representations or warranties, or material breach of its covenants set forth in the merger agreement, and such breach would result in the closing conditions not being satisfied, then the non-terminating party will be required to pay the terminating party $1,500,000 as liquidated damages.

We May Amend or Waive Merger Agreement Provisions (Page )

At any time before completion of the merger, either Enterprise or First Choice may, to the extent legally allowed, waive in writing compliance by the other with any provision contained in the merger agreement. However, once holders of First Choice common stock have approved the First Choice merger proposal, no waiver of any condition may be made that would require further approval by First Choice shareholders unless that approval is obtained.

The Merger Will Be Accounted for Under the Rules for Purchase Accounting (Page )

The merger will be treated as a purchase by Enterprise of First Choice under U.S. generally accepted accounting principles, or GAAP.

Material U.S. Federal Income Tax Consequences of the Mergers (Page )

Subject to certain circumstances described below, and based on certain representations, covenants and assumptions, all of which must continue to be true and accurate in all material respects as of the effective time of the merger, in the opinions of Holland & Knight and Duane Morris, for U.S. federal income tax purposes, the merger will be treated as a reorganization within the meaning of Section 368(a) of the Code. The opinions address the tax consequences of the merger and do not address the tax consequences of the bank merger.

Provided that the merger qualifies as a reorganization for U.S. federal income tax purposes, First Choice shareholders generally will not recognize any gain or loss upon receipt of Enterprise common stock in exchange of First Choice common stock in the merger, except with respect to any cash they receive in lieu of fractional shares of Enterprise common stock.

Tax matters are complicated, and the tax consequences of the merger to a particular First Choice shareholder will depend in part on such shareholder’s individual circumstances. Accordingly, each First Choice shareholder is urged to consult such shareholder’s own tax advisor for a full understanding of the tax consequences of the merger to such shareholder, including the applicability and effect of federal, state, local and foreign income and other tax laws.

For a complete description of the material U.S. federal income tax consequences of the merger, see “Material United States Federal Income Tax Considerations” beginning on page .

You should also read and consider the risk factors relating to the businesses of Enterprise and ownership of Enterprise common stock described in Part I, Item 1A of Enterprise’s Annual Report on Form 10-K for the year ended December 31, 2020 that has been filed with the SEC, as well as any subsequent documents filed by Enterprise with the SEC, which are incorporated into this joint proxy statement/prospectus by reference. See “Where You Can Find More Information” beginning on page . You should also read and consider risk factors relating to the businesses of First Choice that will also affect the combined company after the merger. These risks are described in Part I, Item 1A of First Choice’s Annual Report on Form 10-K for the year ended December 31, 2020 that has been filed with the SEC, as well as any subsequent documents filed by First Choice with the SEC, which are incorporated into this joint proxy statement/prospectus by reference.

Because the market price of Enterprise common stock will fluctuate and the exchange ratio will not be adjusted for such changes, First Choice’s shareholders cannot be certain of the market value of the Enterprise common stock that they will receive upon completion of the merger.

Upon completion of the merger, First Choice shareholders will receive as stock consideration for each share of First Choice common stock they hold immediately prior to the completion of the merger a fixed exchange ratio of 0.6603 of Enterprise common stock. The exchange ratio is fixed in the merger agreement, subject to potential adjustment if pre-closing environmental reviews of First Choice’s real estate result in estimated remediation costs in excess of a specified threshold, and will not be adjusted for changes in the market price of either Enterprise common stock or First Choice common stock. Any change in the market price of Enterprise common stock prior to completion of the merger will affect the value of any shares of Enterprise common stock First Choice shareholders receive as consideration in the merger. The market price of Enterprise common stock may fluctuate as a result of a variety of factors, including general market and economic conditions, changes in business, operations and prospects, and regulatory considerations. Many of these factors are outside our control.

In addition, the merger agreement provides that First Choice may terminate the merger agreement if: the Enterprise daily volume weighted average stock price for the 20 consecutive trading days ending on the trading day immediately preceding the fifth trading day prior to the closing of the merger, which is referred to as the triggering VWAP, is less than $39.704 per share; and (ii) the triggering VWAP underperforms the average closing price of a specified index of financial institution stocks during the 20 trading days ending on the trading day immediately preceding the fifth trading day prior to the closing of the merger by more than 20%. If First Choice elects to terminate the merger agreement in such instance, Enterprise may elect to reinstate the merger agreement by adjusting the exchange ratio to increase the stock consideration. If Enterprise makes such election to reinstate the merger agreement, then no termination will occur and the merger agreement will remain in effect according to its terms (except the stock consideration, which will have been adjusted). Accordingly, at the time of the First Choice special meeting, First Choice shareholders will not know or be able to calculate the market price of Enterprise common stock that they will receive upon completion of the merger.

Some directors and executive officers of First Choice have interests in the merger that may differ from the interests of other shareholders.

In considering the recommendation of the First Choice board of directors to approve the merger, you should be aware that some directors and executive officers of First Choice may have economic interests in the merger other than their interests as shareholders. Pursuant to the terms of the merger agreement, Enterprise is required to take all action necessary to appoint or elect, effective as of the effective time of the merger, one current First Choice director, who must be independent with respect to Enterprise for purposes

TABLE OF CONTENTS

of the listing requirements of Nasdaq, and mutually agreeable to Enterprise and First Choice, as an Enterprise director. Enterprise and First Choice have determined that Peter Hui, the Chairman of the Board of First Choice and FCB, will be appointed to the Enterprise board, with such appointment to be effective as of the effective time of the merger. Mr. Hui will serve until the first annual meeting of the shareholders of Enterprise following the effective time of the merger and until he or his respective successor is elected and qualified.

Certain of the executive officers of First Choice have entered into employment agreements and change in control agreements that provide severance payments and additional benefits upon a change in control of First Choice. In connection with the merger, unvested or unsettled awards of First Choice restricted stock awards granted by First Choice to certain executive officers will vest or be cancelled pursuant to the terms of the applicable First Choice stock plan or award agreement. Unless cancelled, the First Choice restricted stock awards will be exchanged for the stock consideration. In addition, immediately prior to the effective time of the merger, each unvested First Choice option will vest or be forfeited, as the case may be, pursuant to the terms of the applicable First Choice benefit plan and or award agreement. At the effective time, each vested and outstanding First Choice option will be canceled and extinguished and exchanged for the right to receive (without interest) an amount of cash determined in accordance with the merger agreement. The merger agreement also provides for the continued indemnification of First Choice’s current and former directors and executive officers following the merger and for the continuation of directors’ and officers’ insurance for these individuals for six years after the merger. See “The Merger — Interests of First Choice’s Directors and Executive Officers in the Merger” beginning on page .

These arrangements may create potential conflicts of interest. These interests of First Choice’s directors and executive officers may cause some of these persons to view the proposed merger differently than how other First Choice shareholders view it. The First Choice and Enterprise boards of directors were aware of these interests and considered them, among other things, in their approval of the merger agreement and the transactions contemplated by the merger agreement, including the merger. First Choice shareholders should consider these interests in conjunction with the recommendation of the First Choice board of directors with respect to approval of the merger. See “The Merger — Interests of First Choice’s Directors and Executive Officers in the Merger” beginning on page .

Combining Enterprise with First Choice and EB&T with FCB may be more difficult, costly or time-consuming than expected, or could result in the loss of customers.

Enterprise and First Choice, as well as EB&T and FCB, have operated, and until the completion of the merger will continue to operate, independently. It is possible that the integration process could result in the loss of key employees, the disruption of each company’s ongoing business or inconsistencies in standards, controls, procedures and policies that adversely affect each party’s ability to maintain relationships with customers and employees or to achieve the anticipated benefits of the merger. As with any merger of banking institutions, there also may be distributions that cause the loss of customers or cause customers to withdraw their deposits, which could negatively affect the performance and earnings of the combined institutions. There can be no assurance that customers will readily accept changes to their banking arrangements after the merger.

Holders of Enterprise and First Choice common stock will have a reduced ownership and voting interest after the merger and will exercise less influence over management.

Holders of Enterprise and First Choice common stock currently have the right to vote for the election of the directors and on other matters affecting Enterprise and First Choice, respectively. Upon the completion of the merger, each First Choice shareholder will become a stockholder of Enterprise with a percentage ownership of Enterprise common stock that is smaller than such shareholder’s percentage ownership of First Choice common stock. Following completion of the merger, it is currently expected that former holders of First Choice common stock as a group will own approximately 20% of the combined company’s common stock and existing Enterprise stockholders as a group will own approximately 80% of the combined company’s common stock. As a result, holders of Enterprise and First Choice common stock will have less influence on the management and policies of the combined company than they now have on the management and policies of Enterprise or First Choice, as applicable.

TABLE OF CONTENTS

Failure to complete the merger in certain circumstances could require First Choice to pay a termination fee, or in other circumstances, could require Enterprise or First Choice to pay liquidated damages, in addition to transaction expenses.

If the merger agreement is terminated in certain circumstances, First Choice could be required to pay to Enterprise $16,800,000 as a termination fee. If the merger agreement is terminated by either party as a result of the other party’s breach of its representations or warranties, or material breach of its covenants set forth in the merger agreement, and such breach would result in the closing conditions not being satisfied, then the non-terminating party will be required to pay the terminating party $1,500,000 as liquidated damages. Both First Choice and Enterprise have already incurred, and will continue to incur, substantial expenses in connection with the transactions described in this joint proxy statement/prospectus, whether or not the merger is completed and the expected benefits of the merger are realized. See “The Merger Agreement — Termination Fee; Effect of Termination,” beginning on page .

The termination fee and non-solicitation provisions of the merger agreement limit First Choice’s ability to pursue alternatives to the merger with Enterprise.

The merger agreement contains terms and conditions that make it difficult for First Choice to enter into a business combination with a party other than Enterprise. Subject to limited exceptions, First Choice and its directors, officers and agents are prohibited from initiating or knowingly encouraging inquiries with respect to alternative acquisition proposals. The prohibition limits First Choice’s ability to seek offers that may be superior from a financial point of view from other possible acquirers. If First Choice receives an unsolicited superior proposal from a third party that the First Choice board of directors concludes in good faith is superior to the merger proposal and that the failure to take such actions would breach or reasonably be expected to result in a breach of its fiduciary duties, and the merger agreement is terminated, then First Choice would be obligated to pay a $16,800,000 termination fee to Enterprise. The presence of those restrictions in the merger agreement could discourage a competing third party from considering or proposing an acquisition generally, including on better terms than offered by Enterprise. Further, the termination fee might result in a potential competing third party acquirer proposing a lower per share price than it might otherwise have proposed in order to acquire First Choice.

Completion of the merger is subject to the receipt of approvals from regulatory authorities that may impose conditions that could have an adverse effect on us.

Before the merger may be completed, appropriate filings, submissions, or notices must be made to the FDIC, the MDOF, the Federal Reserve, and the CDFPI. These regulatory authorities may impose conditions on the completion of the merger or require changes to the terms of the merger. Although we do not currently expect the imposition of any conditions or changes, there can be no assurance that such conditions or changes will not be imposed. Such conditions or changes could have the effect of delaying completion of the merger or imposition of additional costs on or limiting our revenues following the merger, any of which might have a material adverse effect on us following the merger. Furthermore, we are not obligated to complete the merger if the regulatory approvals received in connection with the merger include certain burdensome conditions, as described in the merger agreement.

The merger cannot be completed unless the Enterprise stockholders approve the Enterprise merger and share issuance proposal and the First Choice shareholders approve the First Choice merger proposal.

In order for the merger to be completed, the Enterprise stockholders must approve the Enterprise merger and share issuance proposal and the First Choice shareholders must approve the First Choice merger proposal. Approval of the Enterprise merger and share issuance proposal under DGCL requires the affirmative vote of at least a majority of the outstanding shares of Enterprise common stock entitled to vote on the Enterprise merger and share issuance proposal at the Enterprise special meeting. Approval of the First Choice merger proposal under the CGCL by the First Choice shareholders requires the affirmative vote of at least a majority of the outstanding shares of First Choice common stock entitled to vote on the First Choice merger proposal at the First Choice special meeting. If any of the required votes is not obtained from the shareholders of each of the respective companies, the merger may not be consummated. Enterprise may terminate the merger agreement if the approval of the First Choice merger proposal has not been

TABLE OF CONTENTS

obtained, and First Choice may terminate the merger agreement if approval of the Enterprise merger and share issuance proposal has not been obtained, in each case, prior to December 31. 2021.

Failure to complete the merger could negatively impact the stock prices and future businesses and financial results of Enterprise and First Choice.

There can be no assurance that the merger will become effective. If the merger is not completed, the ongoing businesses of Enterprise and First Choice may be adversely affected, and Enterprise and First Choice will be subject to a number of risks, including the following:

•

Enterprise and First Choice will be required to pay certain costs relating to the merger, whether or not the merger is completed, such as legal, accounting, financial advisor, proxy solicitation and printing fees;

•

under the merger agreement, First Choice is subject to restrictions on the conduct of its business before completing the merger, which may adversely affect its ability to execute certain of its business strategies if the merger agreement is terminated; and

•

matters relating to the merger may require substantial commitments of time and resources by Enterprise and First Choice management, which could otherwise have been devoted to other opportunities that may have been beneficial to Enterprise or First Choice as independent companies.

In addition, if the merger is not completed, Enterprise and/or First Choice may experience negative reactions from the financial markets and from their respective customers and employees. Enterprise and/or First Choice also could be subject to litigation related to any failure to complete the merger or to proceedings commenced by Enterprise or First Choice against the other seeking damages or to compel the other to perform their obligations under the merger agreement. These factors and similar risks could have an adverse effect on the results of operation, business and stock prices of Enterprise and First Choice.

The merger is subject to certain closing conditions that, if not satisfied or waived, will result in the merger not being completed, which may cause the price of First Choice common stock to decline.

Specified conditions set forth in the merger agreement must be satisfied or waived to complete the merger. If the conditions are not satisfied or waived, to the extent permitted by law, the merger will not occur or will be delayed, and we may lose some or all of the intended benefits of the merger. The conditions described in “The Merger Agreement — Conditions to Completion of the Merger” must be satisfied or waived before Enterprise and First Choice are obligated to complete the merger.

In addition, the merger agreement may be terminated in certain circumstances if the merger is not consummated on or before December 31, 2021, provided that if additional time is necessary to obtain the requisite regulatory approvals, this date may be automatically extended by three months. We cannot assure you that all of the conditions precedent in the merger agreement will be satisfied, or to the extent legally permissible, waived or that the acquisition of First Choice will be completed.

If the merger is not completed, the price of First Choice common stock on the Nasdaq Capital Market may decline to the extent that the current prices reflect a market assumption that the merger will be completed. In addition, First Choice would not realize any of the expected benefits of having completed the merger.

Enterprise may fail to realize the anticipated benefits of the merger.

The success of the merger will depend on, among other things, Enterprise’s ability to realize anticipated cost savings and to combine the businesses of Enterprise and First Choice without materially disrupting the existing customer relationships of Enterprise and First Choice and suffering decreased revenues as a result of the loss of those customers. If Enterprise is not able to successfully achieve these objectives, the anticipated benefits of the merger may not be realized fully or at all or may take longer to realize than expected.

First Choice is subject to business uncertainties and contractual restrictions while the merger is pending.

Uncertainties about the effect of the merger on employees and customers may have an adverse effect on First Choice and consequently on Enterprise. These uncertainties may impair First Choice’s ability to attract,

TABLE OF CONTENTS

retain and motivate key personnel until the merger is completed, and could cause customers and others that deal with First Choice to consider changing existing business relationships with First Choice. Retention of certain employees may be challenging during the pendency of the merger, as certain employees may experience uncertainty about their future roles. If key employees depart because of issues relating to the uncertainty and difficulty of integration or a desire not to remain with the business, First Choice’s business prior to the merger and Enterprise’s business following the merger could be negatively impacted. In addition, the merger agreement restricts First Choice from taking specified actions relative to its business without the prior consent of Enterprise. These restrictions may prevent First Choice from pursuing attractive business opportunities that may arise prior to the completion of the merger. See “The Merger Agreement — First Choice’s Conduct Pending the Merger” beginning on page .

The opinion received by the Enterprise board from its financial advisor, Boenning, and the opinion received by the First Choice board from First Choice’s financial advisor, KBW, do not reflect any changes since the date of such opinions, each of which was delivered prior to the signing of the merger agreement.

Neither the opinion delivered by Boenning to the Enterprise board nor the opinion delivered by KBW to the First Choice board speaks as of any date other than the date of such opinion, which was April 26, 2021 in the case of Boenning’s opinion and April 25, 2021 in the case of KBW’s opinion. Neither Boenning’s opinion nor KBW’s opinion reflects changes that may occur or may have occurred after the date of such opinion, including changes to the operations and prospects of Enterprise or First Choice, changes in general market and economic conditions or regulatory or other factors. Changes in the operations and prospects of Enterprise or First Choice, general market and economic conditions and other factors that may be beyond the control of Enterprise and First Choice may alter the value of Enterprise or First Choice or the market price for shares of Enterprise common stock or First Choice common stock by the time the merger is completed. Boenning’s opinion is attached as Appendix D to this joint proxy statement/prospectus and KBW’s opinion is attached as Appendix E to this joint proxy statement/prospectus. For a description of Boenning’s opinion, see “The Merger — Opinion of Enterprise’s Financial Advisor” beginning on page . For a description of KBW’s opinion, see “The Merger — Opinion of First Choice’s Financial Advisor” beginning on page . For a description of the other factors considered by the Enterprise board in determining to approve the merger, see “The Merger — Enterprise’s Reasons for the Merger; Recommendation of the Enterprise Board of Directors” beginning on page . For a description of the other factors considered by the First Choice board in determining to approve the merger, see “The Merger — First Choice’s Reasons for the Merger; Recommendation of the First Choice Board of Directors” beginning on page .

If the merger does not constitute a reorganization under Section 368(a) of the Code, then First Choice shareholders may be responsible for the payment of additional U.S. federal income taxes related to the merger.

First Choice and Enterprise believe that the merger will qualify as a reorganization within the meaning of Section 368(a) of the Code. However, if the IRS determines that the merger does not qualify as a nontaxable reorganization under Section 368(a) of the Code, then the exchange of First Choice common stock for Enterprise common stock pursuant to the merger would be a taxable transaction, regardless of the form of consideration received in exchange for such First Choice common stock. The merger would be treated for U.S. federal income tax purposes as a taxable sale by First Choice of all of its assets to Enterprise followed by a deemed liquidation of First Choice. First Choice would recognize gain or loss on the deemed taxable sale of all of its assets to Enterprise. In addition, each First Choice shareholder would recognize a gain or loss equal to the difference between the (i) the sum of the fair market value of the stock consideration received by such shareholder in the merger and (ii) such shareholder’s adjusted tax basis in its shares of First Choice common stock surrendered pursuant to the merger.

The shares of Enterprise common stock to be received by First Choice shareholders as a result of the merger will have different rights than shares of First Choice common stock.

Upon completion of the merger, First Choice shareholders will become Enterprise stockholders and their rights as stockholders will be governed by Enterprise’s certificate of incorporation, as amended, and Enterprise’s amended and restated bylaws, as well as the DGCL. The rights associated with First Choice common stock are different from the rights associated with Enterprise common stock. See “Comparison of Stockholder and Shareholder Rights” beginning on page .

TABLE OF CONTENTS

The unaudited pro forma condensed combined financial statements included in this joint proxy statement/prospectus are presented for illustrative purposes only and may not be an indication of the combined company’s financial condition or results of operations following the merger.

The unaudited pro forma condensed combined financial statements contained in this joint proxy statement/prospectus are presented for illustrative purposes only, are based on various adjustments, assumptions and preliminary estimates and may not be an indication of the combined company’s actual financial condition or results of operations following the merger for several reasons. The actual financial condition and results of operations of the combined company following the merger may not be consistent with, or evident from, these unaudited pro forma condensed combined financial statements. In addition, the assumptions used in preparing the unaudited pro forma condensed combined financial statements may not prove to be accurate, and other factors may affect the combined company’s financial condition or results of operations following the merger. Any potential decline in the combined company’s financial condition or results of operations may cause significant variations in the stock price of the combined company.

The market price of the common stock of the combined company after the merger may be affected by factors different from those currently affecting the shares of Enterprise or First Choice common stock.

Upon the completion of the merger, Enterprise stockholders and First Choice shareholders will become stockholders of the combined company. Enterprise’s business differs from that of First Choice, 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 First Choice and Enterprise. For a discussion of the businesses of Enterprise and First Choice, please see the section entitled “Information About the Companies” beginning on page . For a discussion of the businesses of Enterprise and First Choice and of certain factors to consider in connection with such businesses, please see the documents incorporated by reference in this joint proxy statement/prospectus and referred to in the section entitled “Where You Can Find More Information” beginning on page .

Sales of substantial amounts of Enterprise common stock in the open market by former First Choice shareholders could depress Enterprise’s stock price.

Shares of Enterprise common stock that are issued to First Choice shareholders in the merger will be freely tradable without restrictions or further registration under the Securities Act. Based on the number of shares of First Choice common stock outstanding as of April 26, 2021 (which includes the shares of First Choice common stock underlying First Choice restricted stock awards and excludes any assumed conversion of First Choice options), Enterprise currently expects to issue approximately 7,807,656 shares of Enterprise common stock in connection with the merger. If the merger is completed and if First Choice’s former shareholders sell substantial amounts of Enterprise common stock in the public market following completion of the merger, the market price of Enterprise common stock may decrease. These sales might also make it more difficult for Enterprise to sell equity or equity-related securities at a time and price that it otherwise would deem appropriate.

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

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 Enterprise and First Choice. If the effects of the COVID-19 pandemic cause continued or extended decline in the economic environment and the financial results of Enterprise or First Choice, or the business operations of Enterprise or First Choice are disrupted as a result of the COVID-19 pandemic, efforts to complete the merger and integrate the businesses of Enterprise and First Choice 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 Enterprise or First Choice that must be satisfied prior to completion of the merger, which could delay and adversely affect the completion of the merger.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This joint proxy statement/prospectus contains certain forward-looking statements regarding the financial conditions, results of operations, earnings outlook and business prospects of Enterprise, EB&T, First Choice and FCB, and the potential combined company, and may include statements for the periods following completion of the merger. Forward-looking statements are typically identified with the use of terms such as “may,” “might,” “will,” “would,” “should,” “expect,” “plan,” “anticipate,” “believe,” “estimate,” “predict,” “potential,” “could,” “continue,” “intend,” and the negative and other variations of these terms and similar words and expressions, although some forward-looking statements may be expressed differently. Statements about the expected benefits of the merger, including future financial and operating results, plans, objectives, expectations and intentions, and all other statements in this joint proxy statement/prospectus that are not historical facts, constitute forward-looking statements. Forward-looking statements are subject to numerous assumptions, risks and uncertainties, and are subject to change based on factors which are, in many instances, beyond Enterprise’s or First Choice’s control. The ability of Enterprise or First Choice to predict results or the actual effect of future plans or strategies, or those of the combined company, is inherently uncertain. Accordingly, actual results or future events may differ materially from those expressed in, or implied by, the forward-looking statements.

Among the factors that could cause our actual results for future periods to differ materially from those expressed in any forward-looking statements are:

•

the challenges and costs of integrating operations of the business of Enterprise and First Choice;

•

expected revenue synergies, cost savings and other financial or other benefits of the proposed merger between Enterprise and First Choice might not be realized within the expected time frames or might be less than projected;

•

deposit attrition, customer loss or revenue loss following the merger may occur or be greater than expected;

•

business disruption before and following the merger, including diversion of management’s attention and time from ongoing business operations and opportunities;

•

reputational risks and the potential impact of announcement or completion of the merger on customers and employees, including our ability to attract and retain relationship officers and other key personnel;

•

required regulatory, shareholder or other approvals may not be obtained or other closing conditions may not be satisfied in a timely manner or at all;

•

general economic or business conditions, either nationally or in the states or regions in which Enterprise and First Choice do business, may be less favorable than expected, resulting in, among other things, a deterioration in credit quality or a reduced demand for credit;

•

outcomes of litigation and other contingencies;

•

adverse changes in the securities market;

•

consolidation within the banking industry and any existing or changing competition from banks and other financial institutions;

•

burdens imposed by federal and state regulation and any legislation or changes in regulatory requirements; and

•

ongoing impacts caused by the COVID-19 pandemic, including uncertainty and volatility in financial, commodities and other markets, and disruptions to banking and other financial activity, could harm Enterprise and First Choice’s business, financial position and results of operations and adversely affect the timing and anticipated benefits of the merger.

Because these forward-looking statements are subject to assumptions and uncertainties, Enterprise’s and First Choice’s actual results may differ materially from those expressed or implied by these forward-looking statements. These forward-looking statements are predicated on the beliefs and assumptions of the management of each of Enterprise and First Choice based on information known to them as of the date

TABLE OF CONTENTS

of this joint proxy statement/prospectus. Enterprise stockholders and First Choice shareholders are cautioned not to place undue reliance on these statements, which speak only as of the date of this joint proxy statement/prospectus. Enterprise and First Choice undertake no obligation to revise or update any forward-looking statement to reflect events or circumstances after the date of this joint proxy statement/prospectus, or to reflect the occurrence of unanticipated events, unless obligated to do so under federal securities laws. All subsequent written and oral forward-looking statements concerning the merger or other matters addressed in this joint proxy statement/prospectus and attributable to Enterprise or First Choice or any person acting on their behalf are expressly qualified in their entirety by the cautionary statements contained or referred to in this section.

The foregoing list of important factors may not be all inclusive. For a further discussion of these factors and other risks and uncertainties applicable to Enterprise and First Choice, see “Risk Factors” in this joint proxy statement/prospectus and Enterprise’s and First Choice’s other filings with the SEC, including Enterprise’s and First Choice’s Annual Reports on Form 10-K for the year ended December 31, 2020 and Enterprise’s and First Choice’s Quarterly Reports on Form 10-Q for the quarter ended March 31, 2021, as well as any subsequent documents filed by Enterprise and First Choice with the SEC, which are incorporated by reference into this joint proxy statement/prospectus.

Matters to Be Considered

At the Enterprise special meeting, Enterprise stockholders will be asked to consider and vote on the following matters:

A proposal to approve an amendment to Enterprise’s certificate of incorporation to increase the number of authorized shares of Enterprise common stock from 45,000,000 shares to 75,000,000, which is referred to as the Enterprise charter amendment proposal.

A proposal to adjourn or postpone the Enterprise special meeting, if necessary or appropriate, to solicit additional proxies if, immediately prior to such adjournment, there are not sufficient votes to approve the Enterprise merger and share issuance proposal and/or the Enterprise charter amendment proposal, which is referred to as the Enterprise adjournment proposal.

Recommendation of the Enterprise Board of Directors

On April 26, 2021, the Enterprise board of directors unanimously approved the merger agreement and the transactions contemplated thereby, including the merger. Based on Enterprise’s reasons for the merger described in “The Merger — Enterprise’s Reasons for the Merger; Recommendation of the Enterprise Board of Directors” beginning on page , the Enterprise board of directors believes that the merger is advisable and in the best interest of Enterprise and its stockholders.

Accordingly, the Enterprise board of directors unanimously recommends that Enterprise stockholders vote “FOR” the Enterprise merger and share issuance proposal, “FOR” the Enterprise charter amendment proposal and “FOR” the Enterprise adjournment proposal.

Record Date; Quorum

The Enterprise board of directors has fixed the close of business on , 2021 for determining the holders of Enterprise common stock entitled to receive notice of and to vote at the Enterprise special meeting and any adjournments or postponements thereof.

TABLE OF CONTENTS

As of the Enterprise record date, there were shares of Enterprise common stock outstanding and entitled to notice of the Enterprise special meeting, and such outstanding shares of Enterprise common stock were held by approximately holders of record. Each share of Enterprise common stock entitles the holder to one vote at the Enterprise special meeting on each proposal to be considered at the Enterprise special meeting.

The Enterprise special meeting will conduct business only if a majority of the outstanding shares of Enterprise common stock is represented in person or by proxy at the Enterprise special meeting in order to constitute a quorum. If you submit valid proxy instructions or attend the Enterprise special meeting virtually, your shares will be counted to determine whether there is a quorum, even if you abstain from voting. If you fail to provide voting instructions to your broker, bank or other nominee with respect to a proposal, that broker, bank or other nominee will not vote your shares with respect to that proposal.

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

Approval of the Enterprise merger and share issuance proposal requires the affirmative vote of the holders of at least a majority of the outstanding shares of Enterprise common stock entitled to vote on the Enterprise merger and share issuance proposal at the Enterprise special meeting. If you fail to submit a proxy or to vote electronically at the Enterprise special meeting, mark “ABSTAIN” on your proxy or fail to instruct your bank, broker or other nominee (which we refer to as a broker non-vote) with respect to the Enterprise merger and share issuance proposal, it will have the same effect as a vote “AGAINST” the Enterprise merger and share issuance proposal.

Approval of the Enterprise charter amendment proposal requires the affirmative vote of the holders of at least a majority of the outstanding shares of Enterprise common stock entitled to vote on the Enterprise charter amendment proposal at the Enterprise special meeting. If you fail to submit a proxy or to vote electronically at the Enterprise special meeting, mark “ABSTAIN” on your proxy or fail to instruct your bank, broker or other nominee (which we refer to as a broker non-vote) with respect to the Enterprise charter amendment proposal, it will have the same effect as a vote “AGAINST” the Enterprise charter amendment proposal.

Approval of the Enterprise adjournment proposal requires the affirmative vote of at least a majority of the shares of Enterprise common stock present in person or by proxy at the Enterprise special meeting, whether or not a quorum is present. If you fail to submit a proxy or to vote electronically at the Enterprise special meeting, or fail to instruct your bank, broker or other nominee (which we refer to as a broker non-vote) with respect to the Enterprise adjournment proposal, it will have no effect on such proposal. If you mark “ABSTAIN” on your proxy with respect to the Enterprise adjournment proposal, it will have the same effect as a vote “AGAINST” the Enterprise adjournment proposal.

Shares Held by Enterprise Directors and Executive Officers

If your shares are held in “street name” and you wish to vote electronically at the Enterprise special meeting, you will have to obtain a “legal proxy” from your broker, bank or other nominee in advance entitling you to vote at the Enterprise special meeting.

If you are a stockholder of record of Enterprise common stock, voting instructions are included on the enclosed proxy card. If you properly complete and timely submit your proxy, your shares will be voted as you have directed. You may vote for, against or abstain with respect to each matter. If you are a stockholder of record of Enterprise common stock and submit your proxy without specifying a voting instruction, your shares of Enterprise common stock will be voted “FOR” the Enterprise merger and share issuance proposal, FOR” the Enterprise charter amendment proposal and “FOR” the Enterprise adjournment proposal. If your shares are held in street name and you return an incomplete instruction card to your broker, bank or other nominee, that broker, bank or other nominee will not vote your shares with respect to any matter.

Revocability of Proxies and Changes to an Enterprise Stockholder’s Vote

If you hold shares of Enterprise common stock in your name as a stockholder of record on the Enterprise record date, you may change your vote or revoke any proxy at any time before the Enterprise special meeting is called to order by (i) delivering a written notice of revocation to Enterprise, (ii) completing, signing and returning a new proxy card with a later date than your original proxy card prior to such time that your proxy card must be received, and any earlier proxy will be revoked automatically, (iii) logging onto the Internet website specified on your proxy card in the same manner you would to submit your proxy electronically and following the instructions indicated on the proxy card, (iv) calling the toll free number listed on your proxy card and following the recorded instructions, or (v) attending the Enterprise special meeting virtually and voting electronically at the Enterprise special meeting.

Any Enterprise stockholder entitled to vote at the Enterprise special meeting may vote electronically regardless of whether a proxy has been previously given, but your attendance by itself at the Enterprise special meeting will not automatically revoke your proxy unless you give written notice of revocation to the Corporate Secretary of Enterprise before the voting at the Enterprise special meeting is completed or you vote electronically at the meeting.

If you hold shares of Enterprise common stock in your name as a stockholder of record, all written notices of revocation and other communications about revoking your proxy should be addressed to:

Enterprise Financial Services Corp
150 North Meramec
Clayton, Missouri 63105
Attention: Corporate Secretary

If you hold shares of Enterprise common stock in “street name” through a broker, bank or other nominee, you should contact your broker, bank or other nominee to change your vote or revoke your proxy.

TABLE OF CONTENTS

ENTERPRISE PROPOSALS

Proposal 1: The Enterprise Merger and Share Issuance proposal

If you are an Enterprise stockholder, you are being asked to vote to approve the Enterprise merger and share issuance proposal. You should read carefully this entire joint proxy statement/prospectus, including the merger agreement and the other documents included with this joint proxy statement/prospectus. A copy of the merger agreement is attached to this joint proxy statement/prospectus as Appendix A.

The Enterprise board of directors unanimously approved the merger agreement and the transactions contemplated thereby, including the merger. Based on Enterprise’s reasons for the merger described in “The Merger — Enterprise’s Reasons for the Merger; Recommendation of the Enterprise Board of Directors “ beginning on page , the Enterprise board of directors believes that the merger is advisable and in the best interest of Enterprise and its stockholders.

The Enterprise board of directors unanimously recommends that Enterprise stockholders vote “FOR” the Enterprise merger and share issuance proposal.

Proposal 2: The Enterprise Charter Amendment Proposal

If you are an Enterprise stockholder, you are being asked to vote to approve the Enterprise charter amendment proposal to effect an increase the number of authorized shares of Enterprise common stock from 45,000,000 shares to 75,000,000. A copy of the proposed amendment to Enterprise’s certificate of incorporation is attached to this joint proxy statement/prospectus as Appendix C. You should read the proposed certificate of amendment to Enterprise’s certificate of incorporation carefully and in its entirety.

The approval of the Enterprise charter amendment proposal is not required in order to complete the merger and is not a condition to either party’s obligation to complete the merger under the merger agreement. Accordingly, if the Enterprise stockholders do not approve the Enterprise charter amendment proposal, it will have no impact on whether the merger is completed. The Enterprise board of directors considers the Enterprise charter amendment proposal advisable because it will provide greater flexibility in the capital structure of Enterprise following the merger by allowing it to fund potential acquisitions and to pursue other corporate purposes that may be identified by the Enterprise board of directors in the future.

The Enterprise board of directors unanimously recommends that Enterprise stockholders vote “FOR” the Enterprise charter amendment proposal.

Proposal 3: The Enterprise Adjournment Proposal

The Enterprise board of directors seeks the authorization of Enterprise stockholders to direct the vote of the proxies to adjourn or postpone the Enterprise special meeting, if necessary or appropriate, to solicit additional proxies if, immediately prior to such adjournment, there are not sufficient votes to approve the Enterprise merger and share issuance proposal and/or the Enterprise charter amendment proposal.

TABLE OF CONTENTS

If, at the Enterprise special meeting, the number of shares of Enterprise common stock present in person or represented by proxy and voting in favor of the Enterprise merger and share issuance proposal and/or the Enterprise charter amendment proposal is insufficient to approve the Enterprise merger and share issuance proposal and/or the Enterprise charter amendment proposal, as the case may be, Enterprise intends to move to adjourn or postpone the special meeting to a later date or dates in order to enable directors, officers and employees of Enterprise to solicit additional proxies in favor of the Enterprise merger and share issuance proposal and/or the Enterprise charter amendment proposal, as the case may be. In that event, Enterprise will ask Enterprise stockholders to vote upon the Enterprise adjournment proposal, but not the Enterprise merger and share issuance proposal or the Enterprise charter amendment proposal.

The Enterprise board of directors unanimously recommends that Enterprise stockholders vote “FOR” the Enterprise adjournment proposal.

The First Choice special meeting will be a virtual meeting via live webcast on the Internet. You will be able to attend, vote and submit your questions during the First Choice special meeting by visiting http://www. . You will not be able to attend the First Choice special meeting in person.

Matters to Be Considered

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

A proposal to approve the merger agreement and the transactions contemplated thereby, which is referred to as the First Choice merger proposal.

A proposal to adjourn or postpone the First Choice special meeting, if necessary or appropriate, to solicit additional proxies if, immediately prior to such adjournment, there are not sufficient votes to approve the First Choice merger proposal, which is referred to as the First Choice adjournment proposal.

Recommendation of the First Choice Board of Directors

On April 25, 2021, the First Choice board of directors unanimously approved the merger agreement and the transactions contemplated thereby, including the merger. Based on First Choice’s reasons for the merger described in “The Merger — First Choice’s Reasons for the Merger; Recommendation of the First Choice Board of Directors” beginning on page , the First Choice board of directors believes that the merger is advisable and in the best interest of First Choice and its shareholders.

Accordingly, the First Choice board of directors unanimously recommends that First Choice shareholders vote “FOR” the First Choice merger proposal and “FOR” the First Choice adjournment proposal.

Record Date; Quorum

The First Choice board of directors has fixed the close of business on , 2021 for determining the holders of First Choice common stock entitled to receive notice of and to vote at the First Choice special meeting and any adjournments or postponements thereof.

As of the First Choice record date, there were shares of First Choice common stock outstanding and entitled to notice of the First Choice special meeting, and such outstanding shares of First Choice common stock were held by approximately holders of record. Each share of First Choice common stock entitles the holder to one vote at the First Choice special meeting on each proposal to be considered at the First Choice special meeting.

The First Choice special meeting will conduct business only if a majority of the outstanding shares of First Choice common stock is represented in person or by proxy at the First Choice special meeting in order

TABLE OF CONTENTS

to constitute a quorum. If you submit valid proxy instructions or attend the First Choice special meeting virtually, your shares will be counted to determine whether there is a quorum, even if you abstain from voting. If you fail to provide voting instructions to your broker, bank or other nominee with respect to a proposal, that broker, bank or other nominee will not vote your shares with respect to that proposal.

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

Approval of the First Choice merger proposal requires the affirmative vote of at least a majority of the outstanding shares of First Choice common stock entitled to vote on the First Choice merger proposal at the First Choice special meeting. If you fail to submit a proxy or to vote electronically at the First Choice special meeting, mark “ABSTAIN” on your proxy or fail to instruct your bank, broker or other nominee (which we refer to as a broker non-vote) with respect to the First Choice merger proposal, it will have the same effect as a vote “AGAINST” the First Choice merger proposal.

Approval of the First Choice adjournment proposal requires the affirmative vote of the holders of at least a majority of the shares of First Choice common stock entitled to vote and represented in person or by proxy at the First Choice special meeting. If you fail to submit a proxy or to vote electronically at the First Choice special meeting, or fail to instruct your bank, broker or other nominee (which we refer to as a broker non-vote) with respect to the First Choice adjournment proposal, it will have no effect on such proposal. If you mark “ABSTAIN” on your proxy with respect to the First Choice adjournment proposal, it will have the same effect as a vote “AGAINST” the First Choice adjournment proposal.

Shares Held by First Choice Directors and Executive Officers

As of the close of business on the First Choice record date, First Choice directors and executive officers and their affiliates owned and were entitled to vote shares of First Choice common stock, representing approximately % of the outstanding shares of First Choice common stock. All of the directors of First Choice have entered into voting agreements with Enterprise to, among other things, vote the shares of First Choice common stock owned by them in favor of the First Choice merger proposal and other matters required to be approved or adopted to effect the merger and any other transactions contemplated by the merger agreement. As of the close of business on the First Choice record date, the First Choice directors beneficially owned, in the aggregate, approximately % of First Choice common stock. The voting agreements are substantially in the form attached to this joint proxy statement/prospectus as Appendix B. We currently expect that First Choice’s executive officers will vote their shares in favor of the First Choice merger proposal and the First Choice adjournment proposal, although none of them has entered into any agreements obligating them to do so, other than Mr. Robert M. Franko, who is also a director.

Voting by Proxy

You may vote electronically at the First Choice special meeting or by proxy. To ensure your representation at the First Choice special meeting, First Choice recommends that you vote by proxy even if you plan to attend the First Choice special meeting. You can always change your vote at the First Choice special meeting.

If you hold shares of First Choice common stock in your name as a shareholder of record on the First Choice record date, you can vote your shares (i) via telephone or the Internet pursuant to the instructions provided on the enclosed proxy card, (ii) by completing and mailing the enclosed proxy card, or (iii) by voting electronically at the First Choice special meeting.

as you have directed. You may vote for, against or abstain with respect to each matter. If you are a shareholder of record of First Choice common stock and submit your proxy without specifying a voting instruction, your shares of First Choice common stock will be voted “FOR” the First Choice merger proposal and “FOR” the First Choice adjournment proposal. If your shares are held in street name and you return an incomplete instruction card to your broker, bank or other nominee, that broker, bank or other nominee will not vote your shares with respect to any matter.

Revocability of Proxies and Changes to a First Choice Shareholder’s Vote

If you hold shares of First Choice common stock in your name as a shareholder of record on the First Choice record date, you may change your vote or revoke any proxy at any time before the First Choice special meeting is called to order by (i) delivering a written notice of revocation to First Choice, (ii) completing, signing and returning a new proxy card with a later date than your original proxy card prior to such time that your proxy card must be received, and any earlier proxy will be revoked automatically, (iii) logging onto the Internet website specified on your proxy card in the same manner you would to submit your proxy electronically and following the instructions indicated on the proxy card, (iv) calling the toll free number listed on your proxy card and following the recorded instructions, or (v) attending the First Choice special meeting electronically and voting virtually at the First Choice special meeting.

THE MERGER

This section of the joint proxy statement/prospectus describes material aspects of the merger. This summary may not contain all of the information that is important to you. You should carefully read this entire joint proxy statement/prospectus and the other documents we refer you to for a more complete understanding of the merger.

Terms of the Merger

Each of Enterprise’s and First Choice’s respective board of directors has unanimously approved the merger agreement and the transactions contemplated thereby, including the merger. The merger agreement provides that First Choice will merge with and into Enterprise, with Enterprise being the surviving company in the merger. Immediately following the merger, First Choice’s wholly-owned bank subsidiary, FCB, will merge with and into Enterprise’s wholly-owned bank subsidiary, EB&T, with EB&T being the surviving bank in the bank merger. We expect to complete the merger and the bank merger in the third quarter of 2021.

In the merger, each share of First Choice common stock outstanding immediately prior to the effective time of the merger will be converted into the right to receive 0.6603 shares of Enterprise common stock, subject to potential adjustment as provided in the merger agreement, and First Choice shareholders will no longer be owners of First Choice common stock. No fractional shares of Enterprise common stock will be issued in connection with the merger, and holders of First Choice common stock will be entitled to receive cash in lieu thereof.

Enterprise stockholders are being asked to approve the Enterprise merger and share issuance proposal and First Choice shareholders are being asked to approve the First Choice merger proposal. See the section entitled “The Merger Agreement” beginning on page for additional and more detailed information regarding the legal documents that govern the merger, including information about the conditions to the completion of the merger and the provisions for terminating or amending the merger agreement.

Background of the Merger

As part of First Choice’s ongoing efforts to strengthen its business and increase value for shareholders and other constituencies, First Choice’s board of directors and senior management regularly review and assess First Choice’s business plans and strategic opportunities and challenges, including the possibility of pursuing various strategic transactions. In recent years, these strategic discussions have been set against a backdrop of, among other things, business performance, the impact of low interest rates and the challenging regulatory, compliance and competitive environments facing financial institutions generally. First Choice’s board of directors and senior management routinely reviewed strategic alternatives including, among others, acquiring, merging with, or being acquired by another financial institution and a number of balance sheet restructuring opportunities. In addition, First Choice’s board of directors and senior management have evaluated the expected current and future earnings impact of the various strategic alternatives in the context of its capital position, risk appetite, asset and deposit acquisition capabilities and multiple interest rate scenarios. From time to time, First Choice’s board of directors and senior management have discussed various strategic alternatives potentially available to First Choice with its financial advisor, KBW, and have discussed potential strategic transaction opportunities with other financial advisors and banking organizations.

In late August 2019, Mr. Franko had an informal telephone call with the chief executive officer of an unrelated financial institution, which we refer to as Company A, who expressed an interest in exploring a business combination with First Choice. Following that discussion, Mr. Franko asked KBW to provide the First Choice board of directors and senior management with an overview of Company A, its financial performance metrics in the prior three years and the potential pro forma loan and deposit market share and composition of First Choice and Company A (as combined) based on publicly available information. Although there was no formal offer from Company A at the time, an executive session was held following the regular meeting of the First Choice board of directors in September 2019 during which KBW reviewed with the First Choice board of directors a preliminary overview of illustrative pro forma effects of a potential business combination with Company A. The First Choice board of directors determined that, given First Choice’s positive performance and earnings trend throughout 2019 and its prospects for continuing this trend

TABLE OF CONTENTS

in the future, the operational restructuring that Company A was undergoing at the time, and the potential reputational harm that the appearance of a willingness to be acquired would have had on the First Choice franchise, the First Choice board of directors determined that it was not in the best interests of First Choice and its shareholders to solicit an offer or other expression of interest from Company A at that point in time.

Approximately one year later, on August 25, 2020, First Choice received an unsolicited letter addressed to Mr. Franko from Company A expressing an interest in pursuing a business combination transaction pursuant to which First Choice would be merged into Company A to create a combined financial institution with over $10.0 billion in assets in an all-stock transaction. Company A expressed a desire to enter into a non-disclosure and exclusivity agreement with First Choice. However, this letter from Company A did not specify the aggregate consideration or the per share consideration being offered by Company A. Shortly after receiving this unsolicited letter, the First Choice board of directors convened a special meeting on August 26, 2020 to review the letter and approve a response to that letter. Following a review of the unsolicited offer letter, a discussion of regulatory and competitive headwinds facing Company A, the uncertain market environment given the COVID-19 pandemic and its potential effects in the economy, and a comparative review and analysis of the post-combination prospects against the positive earnings trends and strategic initiatives currently underway at First Choice, the First Choice board of directors once again expressed similar concerns and reservations as they had in September 2019 and, accordingly, declined to move forward with any further consideration of the Company A proposal.

At the September 24, 2020 meeting of the First Choice board of directors, at the request of the board of directors as it considered First Choice’s strategic options going forward, representatives of KBW discussed the current economic and regulatory environment and the potential impact of the COVID-19 pandemic on financial institution earnings. This discussion included the impact of technology on competition within the banking industry, the widening technology gap between larger banks and smaller, community banks, which larger banks leverage to better compete within the markets traditionally served by community banks, and the potential that as the economy recovers from the impact of COVID-19, mergers and acquisitions activity within the financial services industry would likely pick up as banks, facing prolonged, downward pressure on their net interest margin and other structural headwinds, look for efficiency gains through mergers and acquisitions. KBW also reviewed, among other things, several potential acquirors of First Choice, including Enterprise, and certain financial metrics of each potential acquiror which informed the First Choice board of directors as to the likelihood and/or ability of each potential acquiror to acquire First Choice. However, given the performance of First Choice in 2019, First Choice’s performance throughout 2020, which saw First Choice on track to achieve record earnings for the full year 2020, and the positive trends going into 2021, including a robust loan pipeline, the First Choice board of directors determined that it was not an appropriate time to solicit potential interest in a business combination from potential acquirors.

On January 19, 2021, Mr. Franko received a written letter from Company A once again expressing interest in exploring a business combination transaction with First Choice. However, unlike the previous letter of interest, Company A’s January 19, 2021 letter of interest included an offer price of $22.25 per share, or approximately $262 million in aggregate consideration, in either all stock or a combination of cash and stock, subject to due diligence. First Choice’s closing stock price on January 15, 2021, which was the last trading day prior to First Choice’s receipt of Company A’s January 19, 2021 letter of interest, was $19.40.

Also on January 19, 2021, Richard Sanborn, a member of Enterprise’s board of directors and the former president of Seacoast Commerce Banc Holdings and Seacoast Commerce Bank, referred to as Seacoast, introduced Enterprise’s Chief Executive Officer, Jim Lally, and Chief Financial Officer, Keene Turner, to Peter Hui, the Chairman of the Board of First Choice and FCB. Mr. Sanborn and Mr. Hui knew each other professionally, and Mr. Hui had previously inquired with Mr. Sanborn as to Mr. Sanborn’s experience in connection with Enterprise’s 2020 acquisition of Seacoast, as well as Mr. Sanborn’s views of Enterprise as an acquisition partner. Mr. Sanborn’s favorable response culminated in the January 19th introduction. On January 22, 2021, Mr. Lally and Mr. Hui had an introductory conversation via telephone.

Company A’s January 19th offer was discussed at the January 25, 2021 regular meeting of the First Choice board of directors, at which representatives of KBW were also present. At the conclusion of the meeting, the First Choice board of directors determined that it would invite Company A’s president to make a presentation to the First Choice board of directors in order to clarify the terms of the offer and the

TABLE OF CONTENTS

perceived benefits and risks of the transaction, as well as give an opportunity for the president of Company A to present his views on Company A’s future prospects.

On January 26, 2021, following First Choice’s release of its fourth quarter 2020 financial results, Mr. Lally contacted Messrs. Franko and Hui to request a meeting to discuss Enterprise’s and First Choice’s respective businesses and strategic opportunities.

On January 27, 2021, the First Choice board of directors convened a special meeting at which senior management of Company A was invited to present in order to clarify the terms of the offer and to be available for questions from the First Choice board of directors. Following this presentation, the First Choice board of directors debated vigorously the merits of Company A’s offer, but determined that, in addition to the perceived transaction risks, the offer of $22.25 was simply too low in light of First Choice’s positive earnings trends going into 2021 and, therefore, declined to enter into a confidentiality and exclusivity agreement for purposes of engaging in further discussions. Following the January 27, 2021 meeting, however, the First Choice board approved establishing a special committee to evaluate, on a preliminary basis, potential business combination partners — either potential acquirors or targets. Named the Strategic Initiatives Committee, this committee was comprised of directors Hui, Thong, Pranav, Jensen and Franko, as well as Mr. Dang. Mr. Hui chaired this committee.

On February 2, 2021, Messrs. Hui and Franko held an introductory meeting with Messrs. Lally and Turner from Enterprise. At this meeting, the parties introduced their respective institutions, organizational histories and strategic focuses. The parties did not discuss the specifics of a strategic transaction, but did express interest in continuing to engage in a constructive dialogue.

A meeting of the Strategic Initiatives Committee was convened on February 18, 2021 for purposes of discussing the potential benefits and challenges of continuing as an independent bank and the potential benefits and challenges of engaging in a strategic combination with another institution. The Strategic Initiatives Committee considered a number of factors, including the growth and composition of FCB’s loan portfolio, FCB’s deposit franchise, management succession, economic indicators and regulatory developments and requirements. The Strategic Initiatives Committee also invited KBW to this meeting to discuss strategic alternatives potentially available to First Choice and review publicly available information on potential strategic opportunities and strategic partners based on possible strategic fit with First Choice and potential financial capacity to complete a transaction. The potential strategic partners reviewed by KBW included Enterprise and two other financial institutions with whom Mr. Hui and Mr. Franko had commenced a dialogue to gauge their interest in a potential strategic transaction with First Choice. Mr. Hui informed the Strategic Initiatives Committee that he had been introduced to Jim Lally, President and Chief Executive Officer of Enterprise, and Keene Turner, Executive Vice President and Chief Financial Officer of Enterprise, and that he and Mr. Franko had participated in an introductory meeting with Messrs. Lally and Turner. Mr. Hui provided additional background on Enterprise, including Mr. Sanborn’s feedback on Enterprise as a partner in a strategic transaction. Mr. Franko informed the Strategic Initiatives Committee that although he and Mr. Hui had commenced a dialogue with two other financial institutions in order to gauge their interest in a potential strategic transaction with First Choice, neither financial institution appeared particularly receptive to continuing a dialogue. Of the various potential strategic partners, the Strategic Initiatives Committee believed that Enterprise had the demonstrated interest and the potential financial capacity to complete such a transaction at a valuation that was attractive relative to First Choice’s performance as a standalone company. After considering its discussion with KBW and other discussions, and in an effort to develop better information regarding First Choice’s strategic options involving combinations with larger banks, the Strategic Initiatives Committee directed Mr. Franko and Mr. Hui to continue their discussions with Enterprise to better gauge their interest in a transaction with First Choice and obtain a sense of its merger philosophy and estimated valuation of First Choice.

On February 22, 2021, Mr. Hui and Mr. Lally had a telephone conversation about a possible business combination and, thereafter, Enterprise and First Choice negotiated and ultimately entered into a customary confidentiality agreement on March 1, 2021 pursuant to which each party exchanged preliminary due diligence information about the other. In addition, over the course of several days following March 1st, various members of management of both Enterprise and First Choice met to evaluate and further discuss the preliminary due diligence information that was provided, including First Choice’s credit portfolio characteristics and interest and non-interest expense profile. One of these follow-up meetings occurred on

TABLE OF CONTENTS

March 11, 2021, between Mr. Turner and Mr. Hui, during which they discussed the potential transaction as well as the respective parties’ business strategy, operating philosophy and organizational culture, and determined to request that Enterprise’s and First Choice’s respective financial advisors begin discussing a potential transaction.

Throughout March 2021, the parties conducted due diligence on each other and, during the second half of the month, negotiated the terms of a non-binding letter of interest from Enterprise, which we refer to as an LOI, which provided for an exclusivity period. From the perspective of the Strategic Initiatives Committee, other than pricing, it was important that the transaction be completed timely in order to prevent reputational harm to First Choice during the pendency of the transaction.

On Friday, March 19, 2021, the Strategic Initiatives Committee convened a meeting to discuss the ongoing due diligence process with Enterprise and the preliminary discussions that had occurred regarding the exchange ratio. Representatives of KBW were present for this meeting and updated the Strategic Initiatives Committee regarding preliminary exchange ratio discussions, conducted at the direction of First Choice, with representatives of Boenning, Enterprise’s financial advisor. The financial advisors communicated the parties’ respective views on a possible exchange ratio. Prior to the March 19th meeting, Boenning, with the consent of Enterprise, had proposed during discussions with KBW an exchange ratio of 0.6550 shares of Enterprise common stock for each share of First choice common stock. Recognizing that the companies’ respective views were not far off, the Strategic Initiatives Committee approved and authorized a counterproposal exchange ratio of not less than 0.6603, which would effectively provide First Choice with a 20% pro forma ownership percentage in the combined company and which was modestly higher than the 0.6550 exchange ratio presented by Boenning. The Strategic Initiatives Committee directed KBW to relay such counterproposal to Boenning and Mr. Hui to relay such counterproposal to Enterprise management. On the evening of March 19, 2021, Mr. Hui and Mr. Turner had a telephone conversation about the proposed consideration and the First Choice shareholders’ pro forma ownership of Enterprise common stock following the proposed transaction, and preliminarily agreed to a pro forma ownership percentage (approximately 20%) that was acceptable to both parties, subject to due diligence and the approval of the First Choice board of directors. First Choice’s closing stock price on Friday, March 19, 2021 was $25.32.

Enterprise’s LOI was formally presented to First Choice on Monday, March 22, 2021. The LOI called for a merger of First Choice into Enterprise in which First Choice shareholders would receive 0.6603 of a share of Enterprise common stock for each share of First Choice common stock, or an implied price of $32.45 per share of First Choice common stock, based on the ten-day volume weighted average price, or VWAP, of Enterprise common stock for the 10 trading days ending on March 19, 2021 ($49.15) and represented an estimated pro forma ownership of 20% for First Choice shareholders. The draft LOI provided Enterprise 45 days of exclusivity from the date of the LOI to conduct full due diligence and to negotiate a definitive merger agreement.

Following Mr. Dang’s review of the LOI, the execution of the LOI was approved by the Strategic Initiatives Committee and ratified by the First Choice board of directors on March 23, 2021. Mr. Franko then executed the LOI and provided the executed LOI to Enterprise. Following the execution of the LOI, representatives of management and the outside advisors to Enterprise and First Choice began more detailed discussions on the potential transaction, and Boenning sent an initial due diligence request list to KBW to allow Enterprise and its advisors to commence credit, operational and legal due diligence of First Choice through an online dataroom established on March 23, 2021.

On April 7, 2021, the Enterprise Nominating & Governance Committee, along with members of Enterprise senior management, met with Mr. Hui to learn more about his experience and background in order to determine whether he could be a potential recommended First Choice director nominee in the event the Enterprise board of directors determined to proceed with the potential transaction and, thereafter, contingent on the approval of the Enterprise board of directors.

On April 8, 2021, Enterprise’s outside legal counsel, Holland & Knight, sent an initial draft of a definitive merger agreement to First Choice’s outside legal counsel, Duane Morris. On April 9, 2021, Duane Morris, Mr. Dang and Mr. Franko met telephonically to discuss the timing of the transaction and the desire of both Enterprise and First Choice management to have a signed definitive agreement and to publicly

announce the transaction by April 26, 2021, the date both Enterprise and First Choice were intending to schedule the publication of their first quarter 2021 earnings release.

On April 13, 2021, Mr. Franko and Mr. Dang met with Duane Morris to discuss comments to the initial draft of the merger agreement, including the scope of the representations, warranties, covenants and closing conditions, employee retention and severance, board representation, tax opinions, termination provisions and termination fees. On April 14, 2021, Duane Morris sent a revised draft of the merger agreement to Holland & Knight.

On April 15, 2021, members of Enterprise’s board of directors, with some members of EB&T's board of directors in attendance, participated in an informational session at which Enterprise’s senior management reported on the status of negotiations and due diligence findings. At this meeting, representatives from Holland & Knight reported on the initial terms of the draft merger agreement, including comments reflected in the revised draft received from Duane Morris, and representatives from Boenning reported on various financial aspects of the proposed transaction.

On April 15, 2021, Holland & Knight sent an initial draft of the voting agreement to Duane Morris. On April 16, 2021, Mr. Dang and Duane Morris discussed their comments to the voting agreement and on April 17, 2021, Duane Morris sent a revised draft of the voting agreement to Holland & Knight.

On April 20, 2021, members of First Choice’s executive management team, with a representative from KBW and Duane Morris also present, interviewed members of Enterprise’s executive management as part of First Choice’s reverse due diligence investigation of Enterprise and in response to a written reverse due diligence request list delivered to Boenning on March 29, 2021, financial and other information regarding Enterprise made available in an online dataroom on April 12, 2021, and an agenda for the April 20, 2021 meeting delivered on April 16, 2021. During this meeting, First Choice received information from Enterprise’s executive management team regarding, among other things, history of recent acquisition activity and benefits received, their assessment of Enterprise’s strengths and weaknesses and information on Enterprise’s prospects, loan quality, compliance with regulatory requirements, information technology and pending litigation.

On April 19, members of EB&T's board of directors participated in an informational session at which Enterprise's senior management reported on the status of negotiations and due diligence findings.

On April 20, 2021, Holland & Knight sent a revised draft of the merger agreement to Duane Morris. On April 22, 2021, Mr. Franko and Mr. Dang met with Duane Morris to discuss comments to the additional edits to the merger agreement and the planned response.

On April 22, 2021, a joint special meeting of the First Choice and FCB boards of directors was held to discuss the progress of the negotiations of the merger agreement and to discuss any remaining issues and the proposed response. At this meeting, Duane Morris also summarized the current draft of the merger agreement and responded to questions regarding the merger agreement.

On April 23, 2021, Holland & Knight and Duane Morris met to discuss the outstanding issues to be resolved in the merger agreement. Over the next two days, Duane Morris and Holland & Knight exchanged drafts of the merger agreement and finalized the merger agreement.

On April 25, 2021, a joint special meeting of the First Choice and FCB boards of directors was held. Representatives of KBW and Duane Morris were also present. Representatives of KBW and Duane Morris summarized the negotiations that had taken place. Mr. Dang reported on the satisfactory results of reverse due diligence meeting with Enterprise’s senior management. At this meeting, KBW reviewed the financial aspects of the proposed transaction and rendered to the First Choice board of directors an opinion (initially rendered verbally and confirmed in written opinion dated April 25, 2021) to the effect that, as of April 25, 2021 and subject to the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by KBW as set forth in its opinion, the exchange ratio in the proposed merger was fair, from a financial point of view, to the holders of First Choice common stock. Duane Morris then reviewed with the First Choice board of directors the First Choice board of directors’ fiduciary duties under applicable law. Following this review, Duane Morris outlined for the directors the terms of the merger agreement, a marked copy of which had been distributed to the directors prior to

TABLE OF CONTENTS

the meeting, and the related voting agreements to be entered into in connection therewith, copies of which had been made available to the directors in advance of the meeting. The boards of directors of First Choice and First Choice Bank then engaged in a vigorous discussion of the terms of the agreements, and the representatives of Duane Morris and KBW as well as Mr. Dang and Mr. Franko answered the First Choice board of directors’ various questions. After extensive discussion and taking into account the factors described below under “— Recommendation of the First Choice Board of Directors,” the boards of directors for First Choice and FCB unanimously adopted resolutions approving the principal terms of the merger agreement and transactions contemplated thereby.

On April 26, 2021, a joint special meeting of the Enterprise and EB&T boards of directors was held. Representatives of Boenning and Holland & Knight participated. Boenning and Holland & Knight summarized the negotiations that had taken place and reviewed the stock consideration to be offered by Enterprise. Holland & Knight outlined for the Enterprise and EB&T boards of directors the terms of the merger agreement, a copy of which had been distributed to the Enterprise and EB&T boards of directors prior to the meeting. Boenning reviewed the financial aspects of the proposed transaction and rendered to the Enterprise and EB&T boards of directors an opinion (initially rendered verbally and confirmed in written opinion dated April 26, 2021) to the effect that, as of April 26, 2021 and subject to the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by Boenning as set forth in its opinion, the exchange ratio in the proposed merger was fair, from a financial point of view, to Enterprise. The Enterprise and EB&T boards of directors then engaged in a vigorous discussion of the terms of the merger agreement and Enterprise senior management, as well as the representatives of Holland & Knight and Boenning, answered the directors’ various questions. After extensive discussion and taking into account the factors described below under “— Enterprise’s Reasons for the Merger”, the Enterprise and EB&T boards of directors unanimously adopted resolutions approving the merger agreement and transactions contemplated thereby.

Following the First Choice and Enterprise boards of directors meetings, the terms of the merger agreement and related agreements were finalized, and the agreements were executed and delivered. The transaction was publicly announced after the close of market on April 26, 2021, in a press release jointly issued by First Choice and Enterprise. Based on a $50.15 per share closing price of Enterprise common stock on April 26, 2021 and 11,824,407 shares of First Choice common stock outstanding on such date, the aggregate stock consideration was approximately $392 million, or $33.11 per share, and the aggregate transaction consideration would include an additional approximately $2.8 million in cash payable to holders of options to acquire 123,632 shares of First Choice common stock with a weighted average exercise price of $11.68 per share.

Enterprise’s Reasons for the Merger; Recommendation of the Enterprise Board of Directors

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

•

management’s view that the acquisition of First Choice provides an attractive opportunity to expand Enterprise’s geographic presence into new markets in California;

•

First Choice’s SBA lending and specialty deposit businesses and its compatibility with Enterprise and its subsidiaries;

•

First Choice’s lending and deposit relationships are not dependent on an extensive traditional branch network;

•

management’s assessment that First Choice presents a strong commercial banking franchise that is consistent with EB&T’s relationship-based banking model while adding talent and depth to EB&T’s operations;

•

management’s review of the business, operations, earnings and financial condition, including capital levels and asset quality, of First Choice and FCB;

TABLE OF CONTENTS

•

management’s due diligence review of First Choice and FCB and the discussions thereof with its financial advisors and legal counsel;

•

the projected impact of the proposed transaction on financial metrics, including earnings per share and tangible book value, the projected earn-back period and the projected internal rate of return;

•

the expectation of management that Enterprise will maintain its strong capital ratios upon completion of the proposed merger;

•

projected efficiencies to come from integrating certain of First Choice operations into Enterprise’s existing operations;

•

the financial and other terms of the merger, including the exchange ratio and stock consideration, the expected tax treatment and the deal protection and termination fee provisions, which Enterprise reviewed with its outside financial and legal advisors;

•

FCB’s compatibility with EB&T, which Enterprise management believes should facilitate integration and implementation of the merger and bank merger, and the complementary nature of the products and customers of FCB and EB&T, which Enterprise management believes should provide the opportunity to mitigate integration risks and increase potential returns;

•

the fact that, concurrently with the execution of the merger agreement, all of First Choice’s directors were entering into voting agreements with Enterprise agreeing to vote for the First Choice merger proposal; and

•

the regulatory and other approvals required in connection with the transactions and the expected likelihood that such regulatory approvals will be received in a reasonably timely manner and without the imposition of burdensome conditions.

The above discussion of the information and factors considered by Enterprise’s board of directors is not intended to be exhaustive, but includes a description of material factors considered by Enterprise’s board of directors. Enterprise’s board of directors further considered various risks and uncertainties related to each of these factors and the ability to complete the merger and bank merger. In view of the wide variety of factors considered by Enterprise’s board of directors in connection with its evaluation of the merger and bank merger, Enterprise’s board did not consider it practical to, nor did it attempt to, quantify, rank or otherwise assign relative weights to the specific factors that it considered. In considering the factors described above, individual directors may have given differing weights to different factors. Enterprise’s board of directors collectively made its determination with respect to the merger and bank merger based on the conclusion reached by its members, based on the factors that each of them considered appropriate, that the merger and bank merger are in the best interests of Enterprise stockholders and that the benefits expected to be achieved from the merger and bank merger outweigh the potential risks and vulnerabilities.

It should be noted that this explanation of the Enterprise 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 under the heading “Cautionary Statement Regarding Forward-Looking Statements” beginning on page .

Based on the reasons stated above, the Enterprise board of directors (i) has determined that the merger is advisable and in the best interest of Enterprise and its stockholders, (ii) has unanimously approved the merger agreement and the transactions contemplated thereby, including the merger, and (iii) unanimously recommends that you vote “FOR” the Enterprise merger and share issuance proposal, “FOR” the Enterprise charter amendment proposal and “FOR” the Enterprise adjournment proposal.

Opinion of Enterprise’s Financial Advisor

Enterprise engaged Boenning to render financial advisory and investment banking services to Enterprise, including an opinion to the Enterprise board of directors as to the fairness, from a financial point of view, to Enterprise of the exchange ratio in the merger. Enterprise selected Boenning because Boenning is a nationally recognized investment banking firm with substantial experience in transactions similar to the merger. As part of its investment banking business, Boenning is continually engaged in the valuation of

TABLE OF CONTENTS

financial services businesses and their securities in connection with merger and acquisitions and other corporate transactions.

As part of its engagement, representatives of Boenning attended the meeting of the Enterprise board of directors held on April 26, 2021 at which the Enterprise board of directors evaluated the proposed merger. At this meeting, Boenning reviewed the financial aspects of the proposed merger and rendered an oral opinion, which was subsequently confirmed in writing, 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 Boenning as set forth in such opinion, the exchange ratio in the merger was fair, from a financial point of view, to Enterprise. The Enterprise board of directors unanimously adopted the merger agreement at this meeting.

The following description of the Boenning fairness opinion is qualified in its entirety by reference to the full text of the opinion, which is attached as Appendix D to this joint proxy statement/prospectus and is incorporated herein by reference, and describes the procedures followed, assumptions made, matters considered, and qualifications and limitations on the review undertaken by Boenning in preparing the opinion.

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

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

In connection with rendering the opinion described above, Boenning reviewed, analyzed and relied upon material bearing upon the financial and operating condition of Enterprise and First Choice and bearing upon the merger, including, among other things:

•

an execution version of the merger agreement, dated as of April 26, 2021;

•

the audited financial statements and the Annual Reports on Form 10-K for the three fiscal years ended December 31, 2020, December 31, 2019, and December 31, 2018 of Enterprise;

•

the unaudited quarterly financial results the fiscal quarter ended March 31, 2021 for Enterprise;

•

the audited financial statements and the Annual Reports on Form 10-K for the three fiscal years ended December 31, 2020, December 31, 2019, and December 31, 2018 of First Choice;

•

the unaudited quarterly financial results for the fiscal quarter ended March 31, 2021 of First Choice;

•

certain publicly available regulatory filings of Enterprise and First Choice and their respective subsidiaries, including (as applicable) the quarterly reports on Form FRY-9C and quarterly call reports filed by EB&T and FCB with respect to each quarter during the three-year period ended December 31, 2020;

•

other interim reports and other communications of Enterprise and First Choice to their respective stockholders and shareholders; and

•

other financial information concerning the respective businesses and operations of Enterprise and First Choice furnished to Boenning by Enterprise and First Choice or which Boenning was otherwise directed to use for purposes of its analysis.

TABLE OF CONTENTS

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

•

the historical and current financial position and results of operations of Enterprise and First Choice;

•

the assets and liabilities of Enterprise and First Choice;

•

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

•

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

•

publicly available consensus “street estimates” of Enterprise for the years ending December 31, 2021 and 2022 published by S&P Global Market Intelligence, as well as assumed Enterprise long term growth rates for the years thereafter as provided to Boenning by Enterprise management, all of which was discussed with Boenning by Enterprise management and used and relied upon by Boenning at the direction of such management and with the consent of the Enterprise board of directors;

•

publicly available consensus “street estimates” of First Choice for the years ending December 31, 2021 and 2022 published by S&P Global Market Intelligence, as well as assumed First Choice long term growth rates provided to Boenning by Enterprise management, all of which was discussed with Boenning by Enterprise management and used and relied upon by Boenning at the direction of such management and with the consent of the Enterprise board of directors; and

•

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

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

In conducting its review and arriving at its opinion, Boenning relied upon and assumed the accuracy and completeness of all of the financial and other information that was provided to it or that was publicly available and did not independently verify the accuracy or completeness of any such information or assume any responsibility or liability for such verification, accuracy or completeness. Boenning relied upon the management of Enterprise as to the reasonableness and achievability of the publicly available consensus “street estimates” of Enterprise and First Choice (and the assumed long-term growth rates of Enterprise and First Choice) referred to above that were provided to or otherwise discussed with Boenning by Enterprise management, and that in each case Boenning was directed by such management to use. Boenning further relied upon Enterprise management as to the reasonableness and achievability of the estimates regarding relevant pro forma financial effects of the merger on Enterprise (including, without limitation, the cost savings and related expenses expected to result or be derived from the merger) referred to above. Boenning assumed, at the direction of Enterprise, that all of the foregoing information was reasonably prepared on bases reflecting, or in the case of the Enterprise and First Choice publicly available “street estimates” referred to above that such estimates were consistent with, the best currently available estimates and judgments of Enterprise management, and that the forecasts, projections and estimates reflected in such information would be realized in the amounts and in the time periods estimated. Accordingly, with the consent of Enterprise, in rendering its opinion, Boenning’s reliance upon Enterprise management as to the reasonableness and achievability of such information included reliance upon the judgments and assessments of Enterprise and Enterprise management with respect to such differences.

TABLE OF CONTENTS

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

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

Boenning assumed, in all respects material to its analyses:

•

the merger would be completed substantially in accordance with the terms set forth in the merger agreement (the final terms of which Boenning assumed would not differ in any respect material to its analyses from the execution version of the merger agreement that had been reviewed) with no adjustments to the financial consideration to be paid and with no other consideration or payments in respect of the First Choice common stock;

•

that any related transactions (including the bank merger) would be completed as contemplated by the merger agreement or as otherwise described to Boenning by representatives of Enterprise;

•

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

•

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

•

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

•

in the course of obtaining the necessary regulatory, contractual, or other consents or approvals for the merger and any related transactions (including the bank merger), no restrictions, including any divestiture requirements, termination or other payments or amendments or modifications, would be imposed that would have a material adverse effect on the future results of operations or financial condition of Enterprise, First Choice or the pro forma entity or the contemplated benefits of the merger, including the cost savings and related expenses expected to result or be derived from the merger.

TABLE OF CONTENTS

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

Boenning’s opinion addressed only the fairness to Enterprise, from a financial point of view, as of the date of such opinion, of the stock consideration to be paid pursuant to the merger agreement. Boenning expressed no view or opinion as to any other terms or aspects of the merger or any term or aspect of any related transaction (including the bank merger) including without limitation, the form or structure of the merger or any related transaction, any consequences of the merger to Enterprise, its stockholders, creditors or otherwise, or any terms, aspects, merits or implications of any employment, retention, consulting, voting, support, cooperation, stockholder or other agreements, arrangements or understandings contemplated or entered into in connection with the merger, any related transaction, or otherwise. Boenning’s opinion was necessarily based upon conditions as they existed and could be evaluated on the date of such opinion and the information made available to Boenning through such date. There has been widespread disruption, extraordinary uncertainty and unusual volatility arising from the effects of the COVID-19 pandemic, including the effect of evolving governmental interventions and non-interventions. Developments subsequent to the date of Boenning’s opinion may have affected, and may affect, the conclusion reached in Boenning’s opinion, and Boenning did not and does not have an obligation to update, revise or reaffirm its opinion. Boenning’s opinion did not address, and Boenning expressed no view or opinion with respect to:

•

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

•

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

•

any business, operational or other plans with respect to First Choice or the pro forma entity that may be currently contemplated by Enterprise or the Enterprise board of directors or that may be made by Enterprise or the Enterprise board of directors subsequent to the closing of the merger;

•

the fairness of the amount or nature of any compensation to any of Enterprise’s or First Choice’s officers, directors or employees, or any class of such persons, relative to any compensation to the holders of Enterprise common stock or First Choice common stock or relative to the financial consideration to be paid;

•

the effect of the merger or any related transaction (including the bank merger) on, or the fairness of the consideration to be received by, holders of any class of securities of Enterprise, First Choice or any other party to any transaction contemplated by the merger agreement;

•

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

•

the prices, trading range or volume at which Enterprise common stock or First Choice common stock will trade following the public announcement of the merger or the prices, trading range or volume at which Enterprise common stock will trade following the consummation of the merger;

•

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

•

any legal, regulatory, accounting, tax or similar matters relating to Enterprise, First Choice, any of their respective stockholders, or relating to or arising out of or as a consequence of the merger or any other related transaction (including the bank merger), including whether or not the merger would qualify as a tax-free reorganization for United States federal income tax purposes.

In performing its analyses, Boenning made numerous assumptions with respect to industry performance, general business, economic, market and financial conditions and other matters, which are beyond the control of Boenning, Enterprise and First Choice. Any estimates contained in the analyses performed by Boenning are not necessarily indicative of actual values or future results, which may be significantly more or less favorable

TABLE OF CONTENTS

than suggested by these analyses. Additionally, estimates of the value of businesses or securities do not purport to be appraisals or to reflect the prices at which such businesses or securities might actually be sold. Accordingly, these analyses and estimates are inherently subject to substantial uncertainty. In addition, the Boenning opinion was among several factors taken into consideration by the Enterprise board of directors in making its determination to approve the merger agreement and the merger. Consequently, the analyses described below should not be viewed as determinative of the decision of the Enterprise board of directors with respect to the fairness of the merger consideration to be paid pursuant to the merger agreement. The type and amount of consideration payable in the merger were determined through negotiation between Enterprise and First Choice, and the decision to enter into the merger agreement was solely that of the Enterprise board of directors.

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

For purposes of the financial analyses described below, Boenning utilized an implied transaction value for the proposed merger of $33.40 per outstanding share of First Choice common stock, based on the fixed exchange ratio of 0.6603 and Enterprise’s closing price of $50.59 on April 23, 2021. Boenning also utilized an implied aggregate transaction value for the proposed merger of $397.8 million based on (i) the implied price of $33.40 per share to First Choice common shareholders, (ii) the “in the money” value of First Choice’s outstanding stock options based on the difference between their weighted average strike price of $11.65 and their implied price of $33.40 (the implied price to First Choice common stock holders), and (iii) 11,824,487 shares of First Choice common stock outstanding, and (iv) 129,162 First Choice stock options outstanding. The aggregate value of the implied price to First Choice common shareholders was $395.0 million while the implied price to First Choice stock option holders was $2.8 million.

In addition to the financial analyses described below, Boenning reviewed with the Enterprise board of directors for informational purposes, among other things, the following implied transaction multiples based on the implied transaction value for the proposed merger of $33.40 per outstanding share of First Choice common stock:

•

188.8% of First Choice’s March 31, 2021 tangible book value per share;

•

11.5x First Choice’s LTM March 31, 2021 earnings per share, (or EPS);

•

10.4x First Choice’s estimated 2021 earnings per share, or EPS, taken from consensus “street estimates” for First Choice, as adjusted to include Enterprise’s estimated transaction related synergies;

•

10.7% core deposit premium defined as the premium paid to First Choice’s tangible book value divided by First Choice’s core deposits as of March 31, 2021; and

•

35.0% premium to First Choice’s April 23, 2021 closing common stock price of $24.75.

Enterprise Selected Companies Analysis. Using publicly available information, Boenning compared the financial performance, financial condition and market performance of Enterprise to 13 major exchange-traded banks and bank holding companies headquartered in the Midwest with total assets between

TABLE OF CONTENTS

$5.0 billion and $20.0 billion and excluded companies that are in the process of being acquired, which we refer to as the Enterprise selected companies.

The Enterprise selected companies were as follows:

	Central Bancompany, Inc.			Meta Financial Group, Inc.
	Heartland Financial USA, Inc.			Horizon Bancorp, Inc.
	First Financial Bancorp			Lakeland Financial Corporation
	First Busey Corporation			QCR Holdings, Inc.
	Merchants Bancorp			Community Trust Bancorp, Inc.
	Park National Corporation			Peoples Bancorp, Inc.
	Premier Financial Corp.

To perform this analysis, Boenning used profitability data and other financial information as of, or for the most recent available completed fiscal quarter (MRQ) for each company, ended December 31, 2020 and March 31, 2021 or latest 12 months, or LTM, and market price information as of April 23, 2021. Boenning also used 2021 and 2022 EPS estimates taken from consensus “street estimates” for the Enterprise selected companies. Certain financial data prepared by Boenning, as referenced in the tables presented below, may not correspond to the data presented in Enterprise’s historical financial statements, or the data prepared by KBW and First Choice presented under the section “The Merger — Opinion of First Choice’s Financial Advisor,” as a result of the different periods, assumptions and methods used by Boenning to compute the financial data presented.

Boenning’s analysis showed the following concerning the financial condition and performance of Enterprise and the Enterprise selected companies for the MRQ:

None of the Enterprise selected companies used as a comparison in the above analyses are identical to Enterprise. Accordingly, an analysis of these results is not mathematical. Rather, it involves complex considerations and judgments concerning differences in financial and operating characteristics of the companies involved.

Discounted Cash Flow Analysis. Boenning performed a discounted cash flow analysis to estimate a range for the implied non-control equity value of First Choice, taking into account the cost savings and related expenses expected to result from the merger as well as certain accounting adjustments assumed with respect thereto. In this analysis, Boenning used estimated earnings data for First Choice, assumed long term earnings and asset growth rates provided by Enterprise management, and estimated cost savings and related expenses and accounting adjustments provided by Enterprise management. Boenning assumed discount rates ranging from 12.7% to 16.7%, with a midpoint of 14.7%. The ranges of values were derived by adding (i) the present value of the estimated excess cash flows that First Choice could generate from 4Q’21 to 2025 and (ii) the present value of First Choice’s implied terminal value at the end of such period, in each case applying estimated cost savings and related expenses and accounting adjustments. Boenning assumed that First Choice would maintain a tangible common equity to tangible assets ratio of 8.50% and First Choice would retain sufficient earnings to maintain that level. In calculating the terminal value of First Choice, Boenning applied a range of 11.5x to 15.5x estimated 2026 earnings, with a midpoint of 13.5x. This discounted cash flow analysis resulted in a range of implied values per share of First Choice common stock, taking into account the cost savings and related expenses expected to result from the merger as well as certain accounting adjustments assumed with respect thereto, of $25.17 per share to $36.05 per share, with a midpoint of $30.26 per share.

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

First Choice Selected Companies. Using publicly available information, Boenning compared the financial performance, financial condition and market performance of First Choice to 15 publicly traded banks and bank holding companies headquartered in the West with total assets between $1.5 billion and $3.2 billion and NPAs to Assets below 1.0%. Companies that are in the process of being acquired were excluded from the First Choice selected companies.

	Northrim BanCorp, Inc.			First Northwest Bancorp
	Cashmere Valley Bank			Timberland Bancorp, Inc.
	FS Bancorp, Inc.			Southern California Bancorp
	PCB Bancorp

To perform this analysis, Boenning used profitability data and other financial information as of, or for the MRQ for each company, ended December 31, 2020 and March 31, 2021 or LTM, and market price information as of April 23, 2021. Boenning also used 2021 and 2022 EPS estimates taken from consensus “street estimates” for the First Choice selected companies.

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

•

Price per common share to tangible book value per share;

•

Price per common share to LTM earnings per share; and

•

Core deposit premium.

The above transaction statistics for the selected transactions were compared with the corresponding transaction statistics for the proposed merger based on the implied transaction value for the proposed merger of $397.8 million and using preliminary historical financial information for First Choice as of or for the 12 months ended March 31, 2021 provided by First Choice’s management.

The results of the analysis are set forth in the following tables:

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

Pro Forma Financial Impact Analysis. Boenning performed a pro forma financial impact analysis that combined projected income statement and balance sheet information of Enterprise and First Choice. Using closing balance sheet estimates as of September 30, 2021 for Enterprise and First Choice provided by consensus “street estimates” and Enterprise management, assumed long term earnings growth rates provided by Enterprise management, and pro forma assumptions (including, without limitation, the cost savings and related expenses expected to result from the merger) provided by Enterprise management, Boenning analyzed the estimated financial impact of the merger on certain projected financial results. This analysis indicated that the merger could be accretive to Enterprise’s 2021 and 2022 estimated EPS and dilutive to Enterprise’s estimated tangible book value per share at closing. Furthermore, the analysis indicated that, pro forma for the merger, Enterprise’s tangible common equity to tangible assets ratio, leverage ratio, common equity Tier 1 ratio, Tier 1 risk-based capital ratio, and Total risk-based capital ratio at closing would be above “well capitalized” regulatory guidelines. For all of the above analysis, the actual results achieved by Enterprise following the merger may vary from the projected results, and the variations may be material.

Miscellaneous. Boenning acted as financial advisor to Enterprise in connection with the merger and did not act as an advisor to or agent of any other person. As part of its investment banking business, Boenning is continually engaged in the valuation of bank and bank holding company securities in connection with acquisitions, negotiated underwritings, secondary distributions of listed and unlisted securities, private placements and valuations for various other purposes. As specialists in the securities of banking companies, Boenning has experience in, and knowledge of, the valuation of banking enterprises. In the ordinary course of its and their broker-dealer businesses, and further to certain existing sales and trading relationships between each of Enterprise and First Choice and certain Boenning affiliates, Boenning and its affiliates may from time to time purchase securities from, and sell securities to, Enterprise and First Choice, and as a market maker in securities, Boenning and its affiliates may from time to time have a long or short position in, and buy or sell, debt or equity securities of Enterprise or First Choice for its and their own accounts and for the accounts of its and their respective customers and clients. Boenning employees and employees of Boenning affiliates may also from time to time maintain individual positions in Enterprise common stock and/or First Choice common stock, which positions currently include an individual position

in shares of Enterprise common stock held by a senior member of the Boenning advisory team providing services to Enterprise in connection with the merger.

Pursuant to the Boenning engagement agreement, Enterprise agreed to pay Boenning a non-refundable cash fee equal to $3,500,000, $50,000 of which became payable upon retention of Boenning, $400,000 of which became payable concurrently with the rendering of Boenning’s fairness opinion, and the balance of which is contingent upon the consummation of the merger. Boenning’s fee for rendering the fairness opinion was not contingent upon Boenning reaching any particular conclusion. Enterprise also agreed to reimburse Boenning for reasonable out-of-pocket expenses and disbursements incurred in connection with its engagement and to indemnify Boenning against certain liabilities relating to or arising out of Boenning’s engagement or Boenning’s role in connection therewith.

In addition to this present engagement, in the two years preceding the date of Boenning’s opinion, Boenning served as exclusive financial advisor to Enterprise in its acquisition of Seacoast Commerce Banc Holdings in 2020 and received a customary fee for its services. In addition, Boenning from time to time provided other investment banking assistance to Enterprise for which Boenning did not enter into any engagement agreement or receive compensation. Boenning has not had any investment banking relationship with First Choice during the past two years in which compensation was received or was intended to be received as a result of the relationship between Boenning, on the one hand, and First Choice, on the other hand.

First Choice’s Reasons for the Merger; Recommendation of the First Choice Board of Directors

The First Choice board of directors has determined that the merger is fair to and in the best interests of First Choice and its shareholders and, by the unanimous vote of all of the directors of First Choice, approved and adopted the merger agreement and the transactions contemplated thereby. In reaching its decision to approve the merger agreement and the transactions contemplated thereby, the First Choice board of directors evaluated the merger and the merger agreement in consultation with First Choice’s executive management as well as First Choice’s legal and financial advisors and determined that the merger was the best option reasonably available for its shareholders in the current uncertain banking market. The First Choice board of directors consulted with First Choice’s executive management regarding the business of First Choice and related financial and strategic matters, also consulted with First Choice’s legal counsel regarding the board’s fiduciary duties, the terms of the merger agreement and related issues, and consulted with First Choice’s financial advisor regarding certain financial matters.

In reaching its determination to approve the merger agreement, the First Choice board of directors considered all factors it deemed material. The First Choice board of directors analyzed information with respect to the financial condition, results of operations, business and prospects of First Choice. In this regard, the First Choice board of directors considered the performance trends of First Choice over the past several years. The board also considered the ability of First Choice to grow as an independent institution, its ability to further enhance shareholder value without engaging in a strategic transaction and the opportunity for First Choice’s shareholders to derive the benefit of the recent increase in First Choice’s share price, Accordingly, the First Choice board of directors considered the long-term as well as the short-term interests of First Choice and its shareholders, including whether those interests might best be served by continued independence.

In reaching its decision to approve the merger agreement and the merger, the First Choice board of directors considered a number of factors, including the following:

•

information with respect to First Choice’s business, earnings, operations, financial condition, asset quality and prospects, and information with respect to Enterprise’s business, earnings, operations, financial condition, asset quality and prospects, the potential cost savings and synergies unique to a transaction between First Choice and Enterprise, taking into account the results of First Choice’s due diligence review of Enterprise and information provided by Enterprise’s management;

•

the recent increase of First Choice’s share price and the opportunity presented by the Enterprise merger for First Choice shareholders to capitalize on this price increase;

•

its belief regarding the lack of prospects for a superior offer for a strategic combination;

TABLE OF CONTENTS

•

its knowledge of the current environment in the financial services industry, including national, regional and local economic conditions and the interest rate environment;

•

consolidation, the uncertainties in the regulatory climate for financial institutions, increased operating costs resulting from regulatory initiatives and compliance mandates, including increasing capital requirements, increasing competition, the current environment for community banks, particularly in Southern California, and current financial market conditions;

•

the financial and growth prospects for First Choice and its shareholders in a business combination with Enterprise as compared to continuing to operate as a stand-alone entity;

•

the greater market capitalization and trading liquidity of Enterprise common stock in the event that First Choice shareholders desire to sell the shares of Enterprise common stock to be received by them following completion of the merger;

•

the merger consideration in the transaction in the form of Enterprise stock, which will allow First Choice’s shareholders to continue to participate in the future success of Enterprise and derive the benefits from Enterprise’s dividends and any synergies achieved or any future transactions that might be pursued by Enterprise;

•

Enterprise’s successful track record, including, among other things, with respect to the integration of acquisitions;

•

the benefits to First Choice and its customers of operating as part of a larger organization, including higher lending limits, potential enhancements to products and services, mitigation of business risks through diversification and greater financial resources;

•

its belief that combining the two companies would create a larger and more diversified financial institution that is both better equipped to respond to economic and industry developments and better positioned to develop and build on its existing market position in Southern California;

•

its assessment of the likelihood that the merger would be completed in a timely manner, including the likelihood that the merger will receive all necessary regulatory approvals in a timely manner;

•

the results of discussions with third parties that the First Choice board of directors believed, in consultation with First Choice’s financial advisor, were the parties likely to have the strategic interest and financial capability to pursue a potential strategic transaction with First Choice;

•

the financial presentation, dated April 25, 2021, of KBW to the First Choice board of directors and the opinion, dated April 25, 2021, of KBW to the First Choice 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 First Choice common stock of the exchange ratio in the proposed merger (see “— Opinion of First Choice’s Financial Advisor” beginning on page );

•

the First Choice board of directors’ belief that the stock consideration exceeds First Choice’s likely value in the absence of a merger, including its potential for future growth, which belief was based on a number of factors, including:

•

the risks and uncertainties associated with maintaining First Choice’s performance as a standalone company; and

•

the First Choice board of directors’ analysis of other strategic alternatives available to First Choice;

•

the expectation that the merger will qualify as a “reorganization” for United States federal income tax purposes; and

•

the terms of the merger agreement, including the fixed exchange ratio, the form of merger consideration, expected tax treatment, the achievability of the closing conditions, deal protection and termination fee provisions, which it reviewed with its outside legal counsel, which terms are described more fully under the section entitled “The Merger Agreement” beginning on page .

In the course of its deliberations regarding the merger, the First Choice board of directors also considered potential risks and potentially negative factors associated with the merger, including the following material factors:

TABLE OF CONTENTS

•

the need to obtain approval by shareholders of First Choice and the stockholders of Enterprise, as well as regulatory approvals, in order to complete the transaction and the risk that those or other conditions will not be satisfied;

•

the risks associated with the operations of the combined company including the challenges both of integrating First Choice’s business, operations and employees with those of Enterprise and of achieving the anticipated cost savings;

•

the fact that the value of the aggregate and per share stock consideration will fluctuate with the market price of Enterprise’s common stock and the risk that Enterprise’s common stock price might decline reducing the aggregate and per share stock consideration from the values at the time the merger agreement was approved;

•

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

•

the risk of potential employee attrition or negative effects on First Choice’s business and customer relationships as a result of the pending merger;

•

the merger-related costs;

•

the fact that executive officers of First Choice have interests in the merger and have arrangements that are different from or in addition to those of First Choice shareholders generally, as described more fully under the section entitled “Interests of First Choice’s Directors and Executive Officers in the Merger” beginning on page ; and

•

the fact that First Choice would be prohibited from affirmatively soliciting acquisition proposals after execution of the merger agreement and will be obligated to pay a termination fee of $16,800,000 to Enterprise if the merger agreement is terminated under certain circumstances, all of which may discourage other parties potentially interested in a strategic transaction with First Choice from pursuing such a transaction.

This description of the information and factors considered by the First Choice board of directors is not intended to be exhaustive, but is believed to include all material factors the First Choice board of directors considered. In determining whether to approve and recommend the merger agreement, the First Choice board of directors did not assign any relative or specific weights to any of the foregoing factors, and individual directors may have weighed factors differently. After deliberating with respect to the merger and the merger agreement, considering, among other things, the reasons discussed above, the First Choice board of directors approved the merger agreement and the merger as being in the best interests of First Choice and its shareholders, based on the total mix of information available to the First Choice board of directors.

This explanation of First Choice’s reasons for the merger and other information presented in this section is forward-looking in nature and should be read in light of the section entitled “Cautionary Statement Regarding Forward-Looking Statements” beginning on page .

Based on the reasons stated above, the First Choice board of directors (i) has determined that the merger is advisable and in the best interest of First Choice and its shareholders, (ii) has unanimously approved the merger agreement and the transactions contemplated thereby, including the merger, and (iii) unanimously recommends that First Choice shareholders vote “FOR” the First Choice merger proposal and “FOR” the First Choice adjournment proposal.

Opinion of First Choice’s Financial Advisor

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

TABLE OF CONTENTS

As part of its engagement, representatives of KBW attended the meeting of the First Choice board of directors held on April 25, 2021, at which the First Choice board of directors evaluated the merger. At this meeting, KBW reviewed the financial aspects of the proposed merger and rendered to the First Choice board an opinion to the effect that, as of such date and subject to the procedures followed, assumptions made, matters considered, and qualifications and limitations on the review undertaken by KBW as set forth in its opinion, the exchange ratio in the proposed merger was fair, from a financial point of view, to the holders of First Choice common stock. The First Choice board of directors approved the merger agreement at this meeting.

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

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

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

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

•

a draft of the merger agreement dated April 20, 2021 (the most recent draft then made available to KBW);

•

the audited financial statements and the Annual Reports on Form 10-K for the three fiscal years ended December 31, 2020 of First Choice;

•

certain preliminary and unaudited quarterly financial results for the quarter ended March 31, 2021 of First Choice (provided by First Choice);

•

the audited financial statements and Annual Reports on Form 10-K for the three fiscal years ended December 31, 2020 of Enterprise;

•

certain preliminary and unaudited quarterly financial results for the quarter ended March 31, 2021 of Enterprise (provided by Enterprise);

•

certain regulatory filings of First Choice and Enterprise and their respective subsidiaries, including the quarterly reports on Form FR Y-9C and call reports filed with respect to each quarter during the three-year period ended December 31, 2020;

•

certain other interim reports and other communications of First Choice and Enterprise to their respective shareholders or stockholders; and

•

other financial information concerning the businesses and operations of First Choice and Enterprise that was furnished to KBW by First Choice and Enterprise or that KBW was otherwise directed to use for purposes of KBW’s analyses.

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

TABLE OF CONTENTS

•

the historical and current financial position and results of operations of First Choice and Enterprise;

•

the assets and liabilities of First Choice and Enterprise;

•

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

•

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

•

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

•

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

•

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

KBW also performed such other studies and analyses as it considered appropriate and took into account its assessment of general economic, market and financial conditions and its experience in other transactions, as well as its experience in securities valuation and knowledge of the banking industry generally. KBW also participated in discussions held by the managements of First Choice and Enterprise regarding the past and current business operations, regulatory relations, financial condition and future prospects of their respective companies and such other matters as KBW deemed relevant to its inquiry. KBW was not requested to, and did not, assist First Choice with soliciting indications of interest from third parties regarding a potential transaction with First Choice.

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

It is understood that the portion of the foregoing financial information of First Choice and Enterprise that was provided to KBW was not prepared with the expectation of public disclosure and that all of the foregoing financial information, including the publicly available consensus “street estimates” of First Choice

TABLE OF CONTENTS

and Enterprise, was based on numerous variables and assumptions that are inherently uncertain (including, without limitation, factors related to general economic and competitive conditions and, in particular, assumptions regarding the ongoing COVID-19 pandemic) and, accordingly, actual results could vary significantly from those set forth in such information. KBW assumed, based on discussions with the respective managements of First Choice and Enterprise and with the consent of the First Choice board of directors, that all such information provided a reasonable basis upon which KBW could form its opinion and KBW expressed no view as to any such information or the assumptions or bases therefor. Among other things, such information assumed that the ongoing COVID-19 pandemic could have an adverse impact on First Choice and Enterprise. KBW relied on all such information without independent verification or analysis and did not in any respect assume any responsibility or liability for the accuracy or completeness thereof.

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

KBW assumed, in all respects material to its analyses:

•

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

•

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

•

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

•

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

•

that in the course of obtaining the necessary regulatory, contractual, or other consents or approvals for the merger and any related transactions, no restrictions, including any divestiture requirements, termination or other payments or amendments or modifications, would be imposed that would have a material adverse effect on the future results of operations or financial condition of First Choice, Enterprise or the pro forma entity, or the contemplated benefits of the merger, including without limitation the cost savings and related expenses expected to result or be derived from the merger.

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

TABLE OF CONTENTS

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

•

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

•

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

•

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

•

the effect of the merger or any related transaction on, or the fairness of the consideration to be received by, holders of any class of securities of First Choice (other than the holders of First Choice common stock, solely with respect to the exchange ratio as described in KBW’s opinion and not relative to the consideration to be received by holders of any other class of securities) or holders of any class of securities of Enterprise or any other party to any transaction contemplated by the merger agreement;

•

any adjustments (as provided in the merger agreement) to the exchange ratio;

•

the actual value of Enterprise common stock to be issued in the merger;

•

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

•

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

•

any legal, regulatory, accounting, tax or similar matters relating to First Choice, Enterprise, their respective shareholders or stockholders, or relating to or arising out of or as a consequence of the merger or any related transaction (including the bank merger), including whether or not the merger would qualify as a tax-free reorganization for United States federal income tax purposes.

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

TABLE OF CONTENTS

in the merger were determined through negotiation between First Choice and Enterprise and the decision of First Choice to enter into the merger agreement was solely that of the First Choice board of directors.

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

For purposes of the financial analyses described below, KBW utilized an implied transaction value for the merger of $33.40 per outstanding share of First Choice common stock, or approximately $397.8 million in the aggregate (inclusive of the implied value of in-the-money First Choice stock options), based on the 0.6603x exchange ratio in the proposed merger and the closing price of Enterprise common stock on April 23, 2021. In addition to the financial analyses described below, KBW reviewed with the First Choice board of directors for informational purposes, among other things, implied transaction multiples for the proposed merger (based on the implied transaction value for the merger of $33.40 per outstanding share of First Choice common stock) of 12.4x First Choice’s estimated calendar year 2021 earnings per share (“EPS”) and 12.8x First Choice’s estimated calendar year 2022 EPS using quarterly financial results for the quarter ended March 31, 2021 of First Choice (provided by First Choice) and publicly available consensus “street estimates” for First Choice.

First Choice Selected Companies Analysis. Using publicly available information, KBW compared the financial performance, financial condition and market performance of First Choice to 16 major exchange-traded banks headquartered in the Western United States (defined as Alaska, Arizona, California, Colorado, Hawaii, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington and Wyoming) with total assets between $1.0 billion and $5.0 billion. Merger targets, ethnic-focused banks, savings banks and thrifts were excluded from the selected companies.

The selected companies were as follows:

	Altabancorp			First Financial Northwest, Inc.
	Bank of Commerce Holdings			First Western Financial, Inc.
	Bank of Marin Bancorp			Heritage Commerce Corp
	BayCom Corp			Northrim BanCorp, Inc.
	California BanCorp			Oak Valley Bancorp
	Central Valley Community Bancorp			Plumas Bancorp
	Coastal Financial Corporation			Sierra Bancorp
	Eagle Bancorp Montana, Inc.			United Security Bancshares

To perform this analysis, KBW used profitability and other financial information as of, or for the latest 12 months (LTM) or the most recent completed fiscal quarter (MRQ) (or, in the case of dividend yield, most recent completed fiscal quarter annualized) periods ended, December 31, 2020 and market price information as of April 23, 2021. KBW also used second, third and fourth fiscal quarters 2021 earnings estimates and 2022 earnings estimates for First Choice taken from publicly available consensus “street estimates” of First Choice and used 2021 and 2022 EPS earnings estimates for the selected companies taken from publicly

TABLE OF CONTENTS

available consensus “street estimates” of the selected companies to the extent publicly available (consensus “street” estimates were not publicly available for three of the selected companies). Where consolidated holding company level financial data for First Choice and the selected companies was unreported, subsidiary bank level data was utilized to calculate ratios (subsidiary bank level data necessary to calculate Total Capital Ratio was also unreported for four of the selected companies). Certain financial data prepared by KBW, and as referenced in the tables presented below, may not correspond to the data presented in First Choice’s historical financial statements, or the data prepared by Boenning presented under the section “Opinion of Enterprise’s Financial Advisor” as a result of the different periods, assumptions and methods used by KBW to compute the financial data presented.

KBW’s analysis showed the following concerning the financial performance of First Choice and the selected companies:

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

Enterprise Selected Companies Analysis. Using publicly available information, KBW compared the financial performance, financial condition and market performance of Enterprise to 17 major exchange-traded U.S. banks headquartered in the Midwestern United States (defined as Illinois, Indiana, Iowa, Kansas, Kentucky, Michigan, Minnesota, Missouri, Nebraska, North Dakota, Ohio, South Dakota and Wisconsin) with total assets between $5.0 billion and $15.0 billion. Merger targets, savings banks and thrifts were excluded from the selected companies.

	First Merchants Corporation			Premier Financial Corp.
	Great Southern Bancorp, Inc.			QCR Holdings, Inc.
	Great Western Bancorp, Inc.			Republic Bancorp, Inc.

KBW also used second, third and fourth fiscal quarters 2021 earnings estimates and 2022 earnings estimates for Enterprise taken from publicly available consensus “street estimates” of Enterprise and used 2021 and 2022 EPS earnings estimates taken from publicly available consensus “street estimates” of the selected companies. Where consolidated

Rather, it involves complex considerations and judgments concerning differences in financial and operating characteristics of the companies involved.

Selected Transactions Analysis. KBW reviewed publicly available information related to 12 U.S. bank transactions announced since January 1, 2021 with announced deal values between $100 million and $1.0 billion. Transactions with foreign buyers were excluded from the selected transactions.

TABLE OF CONTENTS

The selected transactions were as follows:

Acquiror			Acquired Company
Bank of Marin Bancorp			American River Bankshares
Nicolet Bankshares, Inc.			Mackinac Financial Corporation
Eastern Bankshares, Inc.			Century Bancorp, Inc.
Peoples Bancorp Inc.			Premier Financial Bancorp, Inc.
Seacoast Banking Corporation of Florida			Legacy Bank of Florida
Banc of California, Inc.			Pacific Mercantile Bancorp

Stock Yards Bancorp, Inc.			Kentucky Bancshares, Inc.
First Busey Corporation			Cummins-American Corp.
BancorpSouth Bank			FNS Bancshares, Inc.
SVB Financial Group			Boston Private Financial Holdings, Inc.

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

•

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

•

Price per common share to LTM EPS of the acquired company (in the case of two selected transactions involving a private acquired company, this transaction statistic was calculated as total transaction consideration divided by LTM total net income); and

•

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

KBW also reviewed the price per common share paid for the acquired company for the 10 selected transactions involving publicly traded acquired companies as a premium to the closing stock price of the acquired company one day prior to the announcement of the acquisition (expressed as a percentage and referred to as the one-day market premium). The resulting transaction statistics for the selected transactions were compared with the corresponding transaction statistics for the proposed merger based on the implied transaction value for the merger of $33.40 per outstanding share of First Choice common stock and using historical financial information for First Choice as of or for the 12 months ended March 31, 2021 and the closing price of First Choice common stock on April 23, 2021.

Relative Contribution Analysis. KBW analyzed the relative standalone contribution of Enterprise and First Choice to various pro forma balance sheet and income statement items and the combined market capitalization of the combined entity. This analysis did not include purchase accounting adjustments or cost savings. To perform this analysis, KBW used (i) balance sheet and net income data for Enterprise and First Choice as of, or for the fiscal quarter ended, March 31, 2021, (ii) publicly available consensus “street estimates” of Enterprise and First Choice for the second, third and fourth fiscal quarters 2021 and for 2022, and (iii) market price information as of April 23, 2021. The results of KBW’s analysis are set forth in the following table, which also compares the results of KBW’s analysis with the implied pro forma ownership percentages of Enterprise stockholders and First Choice shareholders in the combined company based on the 0.6603x exchange ratio provided for in the merger agreement:

	Enterprise % of Total		First Choice % of Total
Ownership at 0.6603x merger exchange ratio:		80%		20%
Market Information:
Pre-Transaction Market Capitalization		84%		16%
Balance Sheet:
Total Assets		80%		20%
Gross Loans Held for Investment		78%		22%
Total Deposits		82%		18%
Tangible Common Equity		80%		20%
Income Statement:
2021 Estimated Earnings		78%		22%
2022 Estimated Earnings		79%		21%

Financial Impact Analysis. KBW performed a pro forma financial impact analysis that combined projected income statement and balance sheet information of Enterprise and First Choice. Using (i) closing balance sheet estimates as of September 30, 2021 for Enterprise and First Choice taken from publicly available consensus “street estimates,” (ii) publicly available consensus “street estimates” of Enterprise and First Choice for the second, third and fourth fiscal quarters 2021 and for 2022, and (iii) pro forma assumptions (including, without limitation, the cost savings and related expenses expected to result from the merger and certain purchase accounting and other merger-related adjustments and restructuring charges assumed with respect thereto) provided by Enterprise management, KBW analyzed the potential financial impact of the merger on certain projected financial results of Enterprise. This analysis indicated the merger could be accretive to Enterprise’s estimated 2022 EPS and dilutive to Enterprise’s estimated tangible book value per share at closing as of September 30, 2021. Furthermore, the analysis indicated that, pro forma for the merger, each of Enterprise’s tangible common equity to tangible assets ratio, Common Equity Tier 1 Ratio, Leverage Ratio, Tier 1 Capital Ratio and Total Risk-Based Capital Ratio at closing as of September 30, 2021 could be lower. For all of the above analysis, the actual results achieved by Enterprise following the merger may vary from the projected results, and the variations may be material.

First Choice Dividend Discount Model Analysis. KBW performed a dividend discount model analysis of First Choice to estimate a range for the implied equity value of First Choice. In this analysis, KBW used publicly available consensus “street estimates” for First Choice and assumed long-term growth rates for First Choice provided by First Choice management, and assumed discount rates ranging from 12.0% to 16.0%. The range of values was derived by adding (i) the present value of implied future excess capital available for dividends that First Choice could generate over the period from March 31, 2021 through December 31, 2025 as a standalone company, and (ii) the present value of First Choice’s implied terminal value at the end of such period. KBW assumed that First Choice would maintain a tangible common equity to tangible assets ratio of 8.00% and would retain sufficient earnings to maintain that level. In calculating implied terminal values for First Choice, KBW applied a range of 10.0x to 14.0x to First Choice’s estimated

TABLE OF CONTENTS

2026 earnings. This dividend discount model analysis resulted in a range of implied values per share of First Choice common stock of $24.99 to $35.42.

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

Enterprise Dividend Discount Model Analysis. KBW performed a dividend discount model analysis of Enterprise to estimate a range for the implied equity value of Enterprise. In this analysis, KBW used publicly available consensus “street estimates” for Enterprise and assumed long-term growth rates for Enterprise provided by Enterprise management, and assumed discount rates ranging from 10.0% to 14.0%. The range of values was derived by adding (i) the present value of implied future excess capital available for dividends that Enterprise could generate over the period from March 31, 2021 through December 31, 2025 as a standalone company, and (ii) the present value of Enterprise’s implied terminal value at the end of such period. KBW assumed that Enterprise would maintain a tangible common equity to tangible assets ratio of 8.00% and would retain sufficient earnings to maintain that level. In calculating implied terminal values for Enterprise, KBW applied a range of 11.0x to 15.0x to Enterprise’s estimated 2026 earnings. This dividend discount model analysis resulted in a range of implied values per share of Enterprise common stock of $39.17 to $56.17.

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

Pursuant to the KBW engagement agreement, First Choice agreed to pay KBW a cash fee equal to 1.20% of the aggregate merger consideration, $400,000 of which became payable to KBW with the rendering of KBW’s opinion and the balance of which is contingent upon the closing of the merger. First Choice also agreed to reimburse KBW for reasonable out-of-pocket expenses and disbursements incurred in connection with its retention and to indemnify KBW against certain liabilities relating to or arising out of KBW’s engagement or KBW’s role in connection therewith. Other than in connection with the present engagement, in the two years preceding the date of its opinion, KBW did not provide investment banking or financial advisory services to First Choice. In the two years preceding the date of its opinion, KBW did not provide investment banking or financial advisory services to Enterprise. KBW may in the future provide investment banking and financial advisory services to First Choice or Enterprise and receive compensation for such services.

Appraisal or Dissenters’ Rights in the Merger

Enterprise Stockholders

Under Section 262 of the DGCL, the Enterprise stockholders will not be entitled to appraisal or dissenters’ rights in connection with the merger if, on the Enterprise record date, shares of Enterprise

TABLE OF CONTENTS

common stock are listed on a national securities exchange or held of record by more than two thousand (2,000) stockholders, Enterprise stockholders are not required to accept as consideration for their shares any consideration that is different from the consideration to be provided to any other Enterprise stockholder, other than cash instead of fractional shares, and Enterprise stockholders are not required to accept as consideration for their shares anything other than the shares of a domestic entity which immediately after the effective date of merger are either listed on a national securities exchange or held of record by more than 2,000 stockholders, cash paid in lieu of fractional shares or any combination of the foregoing. Enterprise common stock is currently listed on the Nasdaq Global Select Market, a national securities exchange, and is expected to continue to be so listed on the Enterprise record date. If the merger is completed, holders of Enterprise common stock will not receive any consideration, and their shares of Enterprise common stock will remain outstanding and will constitute shares of the combined company, which shares are expected to continue to be listed on the Nasdaq Global Select Market at the effective time. Accordingly, holders of Enterprise common stock are not entitled to any appraisal or dissenters’ rights in connection with the merger.

First Choice Shareholders

First Choice shareholders will not be entitled to appraisal or dissenters’ rights in connection with the merger. Under the CGCL, shareholders are generally entitled to dissent from a merger or consolidation and, in certain circumstances, obtain payment of the fair value of their shares when a merger or consolidation occurs. However, the CGCL provides that appraisal rights are not available where the dissenting shares are listed on a national securities exchange certified by the California Financial Protection and Innovation Commissioner and the merger consideration consists only of shares that are listed on a national securities exchange certified by the California Financial Protection and Innovation Commissioner and cash in lieu of fractional shares. First Choice’s common stock is traded on the Nasdaq Capital Market, a national security exchange certified by the California Financial Protection and Innovation Commissioner, and the merger consideration is comprised only of Enterprise’s common stock, which is traded on the Nasdaq Global Select Market, a national security exchange certified by the California Financial Protection and Innovation Commissioner, and cash in lieu of fractional shares. As such, First Choice shareholders are not entitled to any statutory appraisal or dissenters’ rights.

Regulatory Approvals Required for the Mergers

We have agreed to use commercially reasonable efforts to obtain the regulatory approvals required for the merger and the bank merger. We refer to these approvals, along with the expiration of any statutory waiting periods related to these approvals, as the requisite regulatory approvals. These include approval from or notice to the FDIC, the MDOF, the Federal Reserve and the CDFPI. As of the date of this joint proxy statement/prospectus, Enterprise and First Choice have filed the necessary application with the FDIC, and applications with the Federal Reserve and MDOF are in process and will be filed following the date of this joint proxy statement/prospectus. The mergers and the related transactions cannot proceed in the absence of the requisite regulatory approvals. We cannot assure you as to whether or when the requisite regulatory approvals will be obtained, and, if obtained, we cannot assure you as to the date of receipt of any of these approvals, the terms thereof or the absence of any public protest or litigation challenging them. Likewise, we cannot assure you that the U.S. Department of Justice, or the Department of Justice, or a state attorney general will not attempt to challenge the merger or the bank merger on antitrust grounds, or, if such a challenge is made, as to the result of that challenge.

Any transaction approved by the FDIC under the Federal Bank Merger Act may not be completed until 30 days after the FDIC approval, during which time the Department of Justice may object to the transaction on competitive effects grounds. With the approval of the FDIC and the Department of Justice, the waiting period may be reduced to 15 days. While Enterprise and First Choice do not know of any reason that the Department of Justice would challenge regulatory approval by the FDIC based on competitive effects, and believe that the likelihood of such action is remote, there can be no assurance that the Department of Justice will not initiate such a proceeding, or if such a proceeding is initiated, the result of any such challenge.

Neither Enterprise nor First Choice is aware of any other material governmental approvals or actions that are required prior to the parties’ completion of the mergers other than those described above. We

TABLE OF CONTENTS

presently contemplate that if any additional governmental approvals or actions are required, these approvals or actions will be sought. However, there can be no assurance that any of these additional approvals or actions, if required, will be obtained.

Interests of First Choice’s Directors and Executive Officers in the Merger

In considering the recommendation of the First Choice board of directors with respect to the merger, First Choice shareholders should be aware that certain of the directors and executive officers of First Choice have interests in the merger that may be different from, or in addition to, the interests of First Choice shareholders generally. The First Choice board of directors was aware of these interests and considered them, among other matters, in approving the merger agreement and the transactions contemplated thereby and in making its recommendation that First Choice shareholders vote to approve the First Choice merger proposal. These interests are described in further detail below.

Stock Ownership

As of the close of business on the First Choice record date, First Choice directors and executive officers and their affiliates owned and were entitled to vote shares of First Choice common stock, representing approximately % of the outstanding shares of First Choice common stock. All of the directors of First Choice have entered into voting agreements with Enterprise to, among other things, vote the shares of First Choice common stock owned by them in favor of the First Choice merger proposal and other matters required to be approved or adopted to effect the merger and any other transactions contemplated by the merger agreement. As of the close of business on the First Choice record date, the First Choice directors beneficially owned, in the aggregate, approximately % of First Choice common stock. The voting agreements are substantially in the form attached to this joint proxy statement/prospectus as Appendix B. Each of the directors and executive officers of First Choice will receive the same stock consideration for their shares of First Choice common stock as the other First Choice shareholders.

Treatment of Outstanding Equity Awards

The merger agreement provides that at the effective time of the merger, each unvested or unsettled award of First Choice restricted stock awards will vest or be cancelled pursuant to the terms of the applicable First Choice stock plan or award agreement. Unless cancelled, the First Choice restricted stock awards will be exchanged for the same stock consideration that all other shares of First Choice common stock are entitled to receive in the merger.

TABLE OF CONTENTS

The following table discloses the shares and dollar value of the unvested First Choice restricted shares and First Choice options held by each of First Choice’s directors and executive officers that will accelerate and vest in connection with, and as a result of, the consummation of the merger:

This amount assumes that the 20-day volume weighted average price of Enterprise’s common stock is $[•], determined in accordance with the merger agreement as if the merger closed on [•], 2021, and does not reflect any tax withholding.

Payments Upon Termination or Change in Control

Employment Agreements

First Choice and FCB are parties to employment agreements with each of Robert M. Franko, Director, President and Chief Executive Officer, Khoi D. Dang, Executive Vice President and General Counsel, Gene May, Executive Vice President and Chief Credit Officer, and Yolanda S. Su, Executive Vice President and Chief Operations Administrator. Each of these employment agreements provide for a lump sum bonus after the occurrence of a “change in control” of First Choice (such as the merger) and an executive is terminated other than for “cause,” the executive terminates his or her employment with the surviving company for “good reason” (as defined in his or her employment agreement) or the executive is not retained by the surviving company following a change in control, equal to the product of: (i) a specified multiple, as disclosed in the table below, multiplied by; (ii) such executive officer’s current base salary and the “average bonus” as determined in accordance with their respective employment agreements. As used in the employment agreements, “average bonus” is the average of the aggregate cash bonus, if any, paid or payable to the executive for each of the three fiscal years preceding the fiscal year in which the executive’s termination of employment occurs (or such fewer number of fiscal years for which the executive was eligible to receive a bonus and/or incentive award); provided, however, that if any of the preceding fiscal years includes the year 2019 and any prior years, then the average bonus shall be calculated using the aggregate cash bonus and/or incentive

TABLE OF CONTENTS

award (inclusive of the cash portion and the equity portion thereof) for those years and not any fiscal years subsequent thereto. In addition, upon a “change in control” each executive officer is entitled to continuation of group health, dental and vision benefits for certain period ranging from 18 months to 24 months and immediate vesting of all then-unvested equity grants or awards.

Additionally, under the terms of these employment agreements, if the payments to any executive officer, together with any other payments which such executive officer has the right to receive from First Choice would constitute a “parachute payment” under Internal Revenue Code Section 280G, or 280G, the payments pursuant to the employment will be reduced so that the maximum amount of such payments (after reduction) will be one dollar ($1.00) less than the amount that would cause the aggregate of such payments to be subject to the excise tax imposed by Internal Revenue Code Section 4999 (or nondeductible by First Choice under 280G) or any interest or penalties with respect to such excise tax. However, the aggregate of the payments will only be reduced to the extent the after-tax value of amounts received by the applicable executive officer after application of the above reduction would exceed the after-tax value of the aggregate of these payments without application of such reduction.

The provision of all severance benefits, including severance benefits payable in connection with a change in control of First Choice, is contingent upon such executive officer executing a general release in favor of First Choice.

Management Incentive Plan

Pursuant to the Management Incentive Plan, or the MIP, the Compensation, Nominating and Corporate Governance Committee of First Choice annually approves a set of goals and metrics for annual incentive compensation to be paid to First Choice executive officers in the form of both cash incentives and equity incentives, and which was designed to continue to reflect First Choice’s pay-for-performance culture, to drive growth and profitability and to support First Choice’s principles of safety and soundness. As a result of the closing of the merger, the MIP will terminate and, as a consequence thereof, the First Choice executive officers will receive the prorated portion of their incentive bonuses as determined based on their annualized actual performance metrics. In order for an executive officer participating in the MIP to receive his or her prorated portion of the cash incentive award, he or she must be employed by First Choice on the day prior to the closing of the merger. Cash incentive award payments will be paid based on the actual performance metrics, annualized for the entire year, with the incentive award payment also prorated, based on the number of days in 2021 prior to the closing of the merger divided by 365.

The following table sets forth the cash incentive award that First Choice’s executive officers would be entitled to receive under the MIP, assuming the target award level on a prorated basis and in the event of and assuming consummation of the merger on July 31, 2021, the latest practicable date before the date of this joint proxy statement/prospectus. The actual amounts, if any, to be received by the executive officers may differ from the amounts set forth below:

Appointment of a First Choice Director to Enterprise’s Board of Directors

The merger agreement requires Enterprise to take all action necessary to appoint or elect, effective as of the effective time of the merger, one current First Choice director as a director of Enterprise. The selected First Choice director must be independent with respect to Enterprise for purposes of Nasdaq’s listing requirements and mutually agreeable to Enterprise and First Choice. Enterprise and First Choice have determined that Peter Hui, the Chairman of the Board of First Choice and FCB, will be appointed to the Enterprise board, with such appointment to be effective as of the effective time of the merger. Mr. Hui will serve until the first annual meeting of the stockholders of Enterprise following the effective time of the merger and until he or his successor is elected and qualified.

Indemnification and Insurance of Directors and Officers

Pursuant to the merger agreement, Enterprise has agreed, for a period of six years from the effective time of the merger, to indemnify and hold harmless each present and former director and officer of First Choice and FCB against any costs or expenses (including reasonable attorneys’ fees), judgments, fines, losses, claims, damages or liabilities incurred in connection with any claim, action, suit, proceeding or investigation, arising out of actions or omissions of such persons in the course of performing their duties for First Choice or any of its subsidiaries occurring at or before the effective time of the merger, and to advance expenses to such persons to the same extent such persons would be entitled to expense advancement pursuant to applicable law, the articles of incorporation and bylaws of First Choice as in effect on the date of the merger agreement.

Pursuant to the merger agreement, Enterprise has also agreed to maintain in effect for a period of six years following the effective time of the merger the directors’ and officers’ liability insurance policy currently maintained by First Choice or to provide a policy with comparable or higher coverage, provided that, if the cost of such insurance exceeds 250% of the annual cost paid by First Choice for its existing directors’ and officers’ liability insurance, which is referred to as the maximum insurance amount, Enterprise will obtain the most advantageous coverage as is available for an annual premium equal to the maximum insurance amount.

TABLE OF CONTENTS

THE MERGER AGREEMENT

The following discussion describes the material provisions of the merger agreement and the merger. We urge you to read the merger agreement, which is attached as Appendix A and incorporated by reference in this joint proxy statement/prospectus, carefully and in its entirety. The description of the merger agreement in this joint proxy statement/prospectus has been included to provide you with information regarding its terms. The merger agreement contains representations and warranties made by and to the parties thereto as of specific dates. The statements embodied in those representations and warranties were made for purposes of that contract between the parties and are subject to qualifications and limitations agreed by the parties in connection with negotiating the terms of that contract. In addition, certain representations and warranties were made as of a specified date, may be subject to a contractual standard of materiality different from those generally applicable to shareholders, or may have been used for the purpose of allocating risk between the parties rather than establishing matters as facts.

Structure of the Merger

Pursuant to the terms and conditions of the merger agreement, First Choice will merge with and into Enterprise, with Enterprise being the surviving company. As a result of the merger, the separate existence of First Choice will terminate. Upon the effectiveness of the merger, First Choice shareholders will be entitled to the stock consideration and will no longer be owners of First Choice common stock. Following the merger, certificates for First Choice common stock will only represent the right to receive the stock consideration pursuant to the merger agreement, and otherwise will be null and void after completion of the merger.

Immediately following the merger, First Choice’s wholly-owned bank subsidiary, FCB, will merge with and into Enterprise’s wholly-owned bank subsidiary, EB&T, with EB&T being the surviving bank, which we refer to as the bank merger. EB&T will continue its corporate existence as a state-chartered trust company with banking powers, organized under the laws of the State of Missouri. We expect to complete the merger and the bank merger in the third quarter of 2021.

The Merger Consideration

General. At the effective time of the merger, each outstanding share of First Choice common stock will, by virtue of the merger and without any action on the part of a First Choice shareholder, be converted into, and will be canceled in exchange for, the right to receive whole shares of Enterprise common stock. Cash will be paid in lieu of fractional shares of Enterprise common stock.

Stock Consideration. At the effective time of the merger, each outstanding share of First Choice common stock will be converted into the right to receive to receive 0.6603 shares of Enterprise common stock. If pre-closing environmental reviews of First Choice’s real estate result in estimated remediation costs in excess of a specified threshold, then Enterprise may elect to adjust the exchange ratio to account for those costs.

In addition, the merger agreement provides that First Choice may terminate the merger agreement if (i) the Enterprise daily volume weighted average stock price for the 20 consecutive trading days ending on the trading day immediately preceding the fifth trading day prior to the closing of the merger, which is referred to as the triggering VWAP, is less than $39.704 per share, and (ii) the triggering VWAP underperforms the average closing price of a specified index of financial institution stocks during the 20 trading days ending on the trading day immediately preceding the fifth trading day prior to the closing of the merger by more than 20%. If First Choice elects to terminate the merger agreement in such instance, Enterprise may elect to reinstate the merger agreement by adjusting the exchange ratio to increase the stock consideration. If Enterprise makes such election to reinstate the merger agreement, then no termination will occur and the merger agreement will remain in effect according to its terms (except the stock consideration, which will have been adjusted). Accordingly, at the time of the First Choice special meeting, First Choice shareholders will not know or be able to calculate the market price of Enterprise common stock that they will receive upon completion of the merger.

Upon completion of the merger, First Choice shareholders are expected to receive an aggregate of shares of Enterprise common stock, which, based on an exchange ratio of 0.6603 and a

TABLE OF CONTENTS

$ closing price of Enterprise’s common stock on , 2021, represents approximately $ million of aggregate merger consideration payable to the First Choice shareholders. The aggregate number of shares of First Choice common stock referenced in the immediately prior sentence is based on, as of the date of this joint proxy statement/prospectus, the number of:

•

shares of First Choice common stock outstanding; and

•

unvested or unsettled award of First Choice restricted stock awards.

Following the completion of the merger, and based on the amounts described above and on shares of Enterprise common stock outstanding as of , 2021, the former First Choice shareholders will own approximately 20% of the outstanding shares of Enterprise common stock and the current shareholders of Enterprise will own the remaining approximately 80% of the outstanding shares of Enterprise common stock.

The amounts and percentages in the immediately preceding paragraph do not reflect adjustments based upon, take into account or otherwise give effect to:

•

any shares of First Choice common stock that may be issuable upon exercise of First Choice options prior to the effective time of the merger; or

•

any tax withholding obligations.

Based on the number of shares of First Choice common stock, stock options and restricted stock awards outstanding and the following closing prices of Enterprise’s common stock on the Nasdaq Global Select Market: (i) $50.15 on April 26, 2021, the last trading day before public announcement of the merger agreement and (ii) $ on , 2021, the latest practicable trading day before the date of this joint proxy statement/prospectus, the implied value of the stock consideration per share would be approximately $33.11 and $ , respectively, and the implied value of the aggregate stock consideration would be approximately $392 million and $ million, respectively. The implied value of the stock consideration will fluctuate as the market price of Enterprise common stock fluctuates.

All shares of Enterprise common stock received by First Choice shareholders in the merger will be freely tradable, except that shares of Enterprise common stock received by persons who become affiliates of Enterprise for purposes of Rule 144 under the Securities Act may be resold by them only in transactions permitted by Rule 144, or as otherwise permitted under the Securities Act.

Fractional Shares. No fractional shares of Enterprise common stock will be issued in connection with the merger. Instead, Enterprise will make to each First Choice shareholder, who would otherwise receive a fractional share of Enterprise common stock, a cash payment, without interest and rounded to the nearest whole cent, for the value of any fraction of a share of Enterprise common stock the shareholder would otherwise be entitled to receive, rounded to the nearest hundredth of a share, based on the daily volume weighted average price of Enterprise common stock for the 20 consecutive trading days ending on the trading date immediately preceding the closing date of the merger.

First Choice Options. Immediately prior to the effective time of the merger, each unvested First Choice option will vest or be forfeited, as the case may be, pursuant to the terms of the applicable First Choice benefit plan and or award agreement. At the effective time, each vested and outstanding First Choice option will be canceled and extinguished and exchanged for the right to receive (without interest) an amount of cash equal to the product of (i) the aggregate number of shares of First Choice common stock issuable upon exercise of each such First Choice option and (ii) the excess, if any, of (A) the daily volume weighted average price of Enterprise’s common stock for the 20 consecutive trading days ending on the last trading day immediately preceding the closing date of the merger multiplied by the exchange ratio over (B) the per-share exercise price of such First Choice option, less any applicable taxes required to be withheld with respect to such cash payment. For First Choice options that are exercised before the closing, the underlying shares of First Choice common stock received upon exercise will be exchanged for the stock consideration in accordance with the exchange ratio.

TABLE OF CONTENTS

Other First Choice Stock-Based Awards. At the effective time of the merger, each unvested or unsettled award of First Choice restricted stock awards will vest or be cancelled pursuant to the terms of the applicable First Choice stock plan or award agreement. Unless cancelled, the First Choice restricted stock awards will be exchanged for the stock consideration, as described above under “— Stock Consideration.”

Procedures for Exchanging First Choice Common Stock

Conversion. The conversion of First Choice common stock into the right to receive the stock consideration will occur automatically at the effective time of the merger.

Exchange Procedure. As soon as practicable after the closing of the merger, but in no event later than 10 days thereafter, the exchange agent selected by Enterprise (which may be Enterprise’s transfer agent) and reasonably acceptable to First Choice, which we refer to as the exchange agent, will mail to each holder of a certificate representing shares of First Choice, which we refer to as certificates, and each holder of a book-entry share(s) representing outstanding shares of First Choice common stock, which we refer to as book-entry shares, a letter of transmittal and instructions advising such holder of the effectiveness of the merger and the procedure for surrendering to the exchange agent certificates or book-entry shares of First Choice common stock in exchange for the stock consideration allocated to them.

First Choice shareholders who surrender their certificates or book-entry shares and duly complete and execute the transmittal materials, or who have taken other steps to surrender the evidence of their stock interest in First Choice in accordance with the instructions accompanying the letter of transmittal, will, upon the exchange agent’s acceptance of such certificates or book-entry shares and transmittal materials or stock interest, be entitled to (i) a certificate (or evidence of shares in book-entry form, as applicable) representing the number of whole shares of Enterprise common stock that such holder is entitled to receive pursuant to the merger agreement, and (ii) a check in the amount (after giving effect of any tax withholding as described below) equal to (A) the amount of any cash payable in lieu of fractional shares of Enterprise common stock, and (B) any dividends and other distributions payable with respect to the shares of Enterprise common stock issuable to such holder, in each case in accordance with the terms of the merger agreement. No interest will accrue or be paid with respect to any cash paid in lieu of fractional shares of First Choice common stock.

Dividends and Distributions. Any First Choice shareholder who receives shares of Enterprise common stock in the merger will receive dividends on Enterprise common stock or other distributions declared after the completion of the merger only if he or she has surrendered his or her certificates or book-entry shares. Only then will the First Choice shareholder be entitled to receive all previously withheld dividends and distributions, without interest.

Withholding. The exchange agent will be entitled to deduct and withhold from the stock consideration payable to any First Choice shareholder the amounts it is required to deduct and withhold under any federal, state, local or foreign tax law. If the exchange agent withholds any amounts, these amounts will be treated for all purposes of the merger as having been paid to the shareholders from whom they were withheld.

No Transfers of First Choice Common Stock after the Merger. After completion of the merger, no transfers of First Choice common stock issued and outstanding immediately prior to the completion of the merger will be allowed. First Choice stock certificates that are presented for transfer after the completion of the merger will be canceled and exchanged for the stock consideration.

Lost, Stolen or Destroyed First Choice Common Stock Certificates. If a First Choice shareholder has lost such shareholder’s certificate, or the certificate has been lost, stolen or destroyed, the First Choice shareholder may be required to deliver an affidavit and a lost certificate bond as a condition to receiving any stock consideration to which such shareholder may be entitled. If you are unable to locate your original stock certificate(s), you should contact the exchange agent, Computershare Trust Company, NA, at (800) 546-5141.

Closing and Effective Time

We plan to complete the merger at such date and time mutually agreed by Enterprise and First Choice, which such date may not be later than 15 business days after all of the conditions to the closing of the merger

TABLE OF CONTENTS

have been satisfied or waived in accordance with the terms of the merger agreement. The time the merger is completed is the effective time of the merger. See “The Merger Agreement — Conditions to Completion of the Merger” beginning on page .

Management after the Merger

Upon the effective time of the merger and the effectiveness of the bank merger, the separate existence of First Choice and FCB will cease. The directors and executive officers of Enterprise and EB&T immediately prior to the merger and bank merger, respectively, will continue as the directors and executive officers of Enterprise and EB&T after the merger and bank merger, respectively, in each case, until their respective successors are duly elected or appointed and qualified. Pursuant to the terms of the merger agreement, Enterprise is required to take all action necessary to appoint or elect, effective as of the effective time of the merger, one current First Choice director. The selected First Choice director must be independent with respect to Enterprise for purposes of Nasdaq’s listing requirements and mutually agreeable to Enterprise and First Choice. Enterprise and First Choice have determined that Peter Hui, the Chairman of the Board of First Choice and FCB, will be appointed to the Enterprise board, with such appointment to be effective as of the effective time of the merger. Mr. Hui will serve until the first annual meeting of the stockholders of Enterprise following the effective time of the merger and until he or his successor is elected and qualified.

Representations and Warranties of the Parties

Pursuant to the merger agreement, Enterprise, EB&T, First Choice and FCB made certain customary representations and warranties relating to their respective companies, subsidiaries, businesses and matters related to the merger and bank merger. For detailed information concerning these representations and warranties, reference is made to Articles 3 and 4 of the merger agreement included as Appendix A to this joint proxy statement/prospectus. Such representations and warranties generally must remain materially accurate through the completion of the merger.

The merger agreement contains representations and warranties that Enterprise, EB&T, First Choice and First Choice Bank made to and solely for the benefit of each other. These representations and warranties are subject to materiality standards which may differ from what may be viewed as material by investors and shareholders, and, in certain cases, were used for the purpose of allocating risk among the parties rather than establishing matters as facts. The assertions embodied in those representations and warranties also are qualified by information in confidential disclosure schedules that the parties have exchanged when signing the merger agreement. The disclosure schedules contain information that modifies, qualifies and creates exceptions to the representations and warranties in the merger agreement. Accordingly, neither shareholders of either First Choice or Enterprise should rely on the representations and warranties as characterizations of the actual state of facts or condition of Enterprise or First Choice, since they were only made as of the date of the merger agreement and are modified in important part by the underlying disclosure schedules. Moreover, information concerning the subject matter of the representations and warranties may have changed since the date of the merger agreement, which subsequent information may or may not be fully reflected in Enterprise’s or First Choice’s public disclosures.

First Choice’s Conduct Pending the Merger

The merger agreement contains various restrictions on the operations of First Choice before the effective time of the merger. In general, the merger agreement obligates First Choice and FCB to conduct their business in the usual, regular and ordinary course of business consistent with past practice. In addition, First Choice and FCB have agreed that, except as expressly contemplated by the merger agreement or as required by applicable law, without the prior written consent of Enterprise (such consent not to be unreasonably withheld or delayed), neither will, among other things:

•

issue, sell, grant, pledge, encumber, dispose of or otherwise permit to become outstanding any shares of its capital stock or any other securities;

Enterprise’s Conduct Pending the Merger

The merger agreement also obligates Enterprise and EB&T to conduct business in the ordinary course of business consistent and in compliance in all material respects with all applicable laws. In addition, Enterprise and EB&T have agreed that, except as expressly contemplated by the merger agreement, without the prior written consent of First Choice (such consent not to be unreasonably withheld or delayed), neither will, among other things:

•

agree to take, make any commitment to take, or adopt any resolutions of the Enterprise board in support of, any of the actions reasonably believed to be covered above and as described in the merger agreement.

No Solicitation

Except as otherwise set forth in the merger agreement, First Choice has agreed that it will not, and will instruct its directors, officers and employees not to, directly or indirectly:

•

initiate, solicit, induce or knowingly encourage, or knowingly take any action to facilitate the making of, any inquiry, offer or proposal which constitutes, or could reasonably be expected to lead to, an acquisition proposal;

•

participate in discussions or negotiations regarding any acquisition proposal or furnish, or otherwise afford access, to any person, any information or data with respect to First Choice or its subsidiaries or otherwise in furtherance of an acquisition proposal;

TABLE OF CONTENTS

•

release any person from, waive any provision of, or fail to enforce any confidentiality agreement or standstill agreement to which First Choice is a party in furtherance of an acquisition proposal; or

•

enter into any agreement, agreement in principle or letter of intent with respect to any acquisition proposal or approve or resolve to approve any acquisition proposal or any agreement, agreement in principle or letter of intent relating to any acquisition proposal.

First Choice has agreed that any violation of the foregoing restrictions by any of its representatives shall be deemed to be a breach of the merger agreement by First Choice. In addition, First Choice and its subsidiaries are required to, and are required to cause each of First Choice’s representatives to, immediately cease and cause to be terminated any and all existing discussions, negotiations, and communications with any persons with respect to any existing or potential acquisition proposal.

For purposes of the merger agreement, “acquisition proposal” is defined to mean any inquiry, offer or proposal (other than an inquiry, offer or proposal from Enterprise), whether or not in writing, contemplating, relating to, or that could reasonably be expected to lead to, an acquisition transaction. An “acquisition transaction” means:

•

any transaction or series of transactions involving any merger, consolidation, recapitalization, share exchange, liquidation, dissolution or similar transaction involving First Choice or any of its subsidiaries;

•

any transaction pursuant to which any third party or group acquires or would acquire (whether through sale, lease or other disposition), directly or indirectly, an aggregate amount of 20% or more of the assets of First Choice and any of its subsidiaries on a consolidated basis;

•

any issuance, sale or other disposition of (including by way of merger, consolidation, share exchange or any similar transaction) securities (or options, rights or warrants to purchase or securities convertible into, such securities) representing an aggregate of 20% or more of the voting power of First Choice;

•

any tender offer or exchange offer that, if consummated, would result in any third party or group beneficially owning an aggregate of 20% or more of any class of equity securities of First Choice; or

•

any transaction which is similar in form, substance or purpose to any of the transactions listed above, or any combination of these types of transactions.

If First Choice receives a bona fide unsolicited written acquisition proposal that did not result from a breach of the non-solicitation provisions described above, then, prior to First Choice’s shareholders approving the merger agreement and transactions contemplated by the merger agreement, the First Choice board of directors may participate in discussions or negotiations regarding the unsolicited acquisition proposal if the First Choice board of directors first reasonably determines in good faith, after consultation with its outside legal counsel and outside financial advisor, that such acquisition proposal constitutes or could reasonably be expected to lead to a superior proposal, and its failure to take action on such proposal would breach or reasonably be expected to result in a breach of its fiduciary duties to First Choice’s shareholders under applicable law.

For purposes of the merger agreement, a “superior proposal” means any bona fide, unsolicited written acquisition proposal (on its most recently amended or modified terms, if amended or modified) made by a third party to enter into an acquisition transaction that (i) the First Choice board of directors determines in good faith, after consulting with its outside legal counsel and its financial advisor, would, if consummated, result in a transaction that would be more favorable to First Choice’s shareholders than the merger (taking into account all factors relating to such proposed transaction deemed relevant by the First Choice board of directors, including without limitation the amount and form of consideration, the timing of payment, the risk the transaction would not be consummated, the financing of the transaction and all other conditions thereto, the termination fee described below under “The Merger Agreement — Termination Fee; Effect of Termination,” and any adjustments to the terms and conditions of the merger proposed by Enterprise in response to such acquisition proposal), and (ii) is for 50% or more of the outstanding shares of First Choice common stock or all or substantially all of the assets of First Choice.

TABLE OF CONTENTS

In addition to the obligations described above, First Choice will promptly, within 24 hours, notify Enterprise in writing if any proposals or offers are received by, any information is requested from, or any negotiations or discussions are sought to be initiated or continued with, First Choice or any of its representatives, in each case in connection with any acquisition proposal.

First Choice Board’s Covenant to Recommend the Merger Agreement

Pursuant to the merger agreement, except as described below with respect to “subsequent determinations,” the First Choice board is required, at all times prior to and during the First Choice special meeting, to recommend that First Choice shareholders approve the merger agreement and the transactions contemplated by the merger agreement. Subject to certain exceptions, First Choice agreed that its board of directors, or any committee of the board, will not:

•

withhold, withdraw, change, qualify, amend or modify, or publicly propose to withdraw, change, qualify, amend or modify, in a manner adverse in any respect to the interest of Enterprise, or take any other action or make any other public statement inconsistent with its recommendation for approval by First Choice shareholders of the merger agreement and the transactions contemplated by the merger agreement or any other matters required to be approved by First Choice shareholders for consummation of the merger and the transactions contemplated thereby;

•

fail to publicly affirm its recommendation for approval of the merger agreement and the transactions contemplated by the merger agreement within five business days following a request by Enterprise;

•

approve or recommend, or publicly propose to approve or recommend, any acquisition proposal;

resolve to take, or publicly announce an intention to take, any of the foregoing actions; or

The actions described in the first four bullet points listed above are referred to as a “subsequent determination.” Pursuant to the merger agreement, the First Choice board or any First Choice board committee may take a “subsequent determination” if First Choice receives an acquisition proposal and:

•

the First Choice board of directors determines in good faith, after consultation with outside legal counsel and its financial advisor, that the acquisition proposal constitutes a superior proposal and that the failure to make a subsequent determination with respect to the superior proposal be breach or reasonably be expected to result in a breach of its fiduciary duties, and

•

provided that, during the five business days after Enterprise’s receipt from First Choice of a notice regarding the First Choice board’s subsequent determination, First Choice and its board of directors negotiate in good faith with Enterprise, to the extent that Enterprise desires to negotiate, to make such adjustments, modifications or amendments to the terms and conditions of the merger agreement as would enable First Choice to proceed with the First Choice recommendation of the merger agreement and transactions contemplated by the merger agreement.

In the event of any material revisions to the superior proposal, First Choice must provide a new notice of such superior proposal to Enterprise. During the three business day period following receipt of such new written notice by Enterprise, First Choice and its board of directors must negotiate in good faith with Enterprise, to the extent that Enterprise desires to negotiate, to make any adjustments, modifications or amendments to the terms and conditions of the merger agreement as would enable First Choice to proceed with its board’s original recommendation with respect to the merger agreement without requiring First Choice to withdraw, qualify, amend or modify its board’s recommendation with respect to the merger agreement.

Enterprise Board’s Covenant to Recommend the Merger Agreement

Pursuant to the merger agreement, the Enterprise board is required, at all times prior to and during the Enterprise special meeting, to recommend that Enterprise shareholders approve the merger agreement and the transactions contemplated by the merger agreement. Enterprise agreed that its board of directors, or any

committee of the board, will not withhold, withdraw, change, qualify, amend or modify, or publicly propose to withdraw, change, qualify, amend or modify, in a manner adverse in any respect to the interest of First Choice, or take any other action or make any other public statement inconsistent with, its recommendation to approve the merger agreement and the transactions contemplated by the merger agreement.

one First Choice director must become a member of the Enterprise board of directors as of the effective time of the merger; and

•

the authorization to list the shares of Enterprise common stock issuable in connection with the merger on Nasdaq, subject to official notice to Nasdaq of the issuance.

The parties may waive conditions to their obligations unless they are legally prohibited from doing so. Shareholder approval and regulatory approvals may not be legally waived.

Amendment of the Merger Agreement

To the extent permitted under applicable law, the merger agreement may be amended or supplemented at any time by written agreement of the parties whether before or after the approval of the shareholders of

TABLE OF CONTENTS

First Choice, except that after shareholders of First Choice have approved the merger agreement, no amendment or supplement that by law requires further approval by the shareholders of First Choice may be made without first obtaining such approval.

Termination of the Merger Agreement

Enterprise and First Choice can at any time agree, by mutual written consent, to terminate the merger agreement without completing the merger, even if First Choice has received approval of the First Choice merger proposal by its shareholders and Enterprise has received approval of the Enterprise merger and share issuance proposal by its stockholders. Also, either party can decide, without the consent of the other, to terminate the merger agreement in certain circumstances, including:

•

if (i) there is a final non-appealable denial of a required regulatory approval or an application for a required regulatory approval has been withdrawn upon the request of the applicable governmental authority, (ii) any required regulatory approval includes any of the conditions described in the sixth bullet point under “— Conditions to Completion of the Merger” above, or (iii) a court of competent jurisdiction or other governmental authority issues a final, non-appealable order, decree, ruling or takes other action restraining, enjoining or otherwise prohibiting the transactions contemplated by the merger agreement; provided, however, that no party has a right to terminate the merger agreement if such denial is due to the failure of the party seeking to terminate the merger agreement to perform or observe the covenants set forth in the merger agreement;

•

if the terminating party is not then in material breach of any representation, warranty, covenant, or agreement contained in the merger agreement, in the event of a material breach by the other party of any of its covenants or agreements in the merger agreement that (i) cannot be or has not been cured within 30 days’ written notice to the breaching party, or 60 days if such breach cannot reasonably be cured within 30 days and such cure is able to be cured within 60 days and is being diligently pursued, and (ii) would entitle the non-breaching party not to consummate the merger under the merger agreement;

•

if there is a continuing breach of a representation or warranty contained in the merger agreement or a continuing material breach of the merger agreement by a party, and the breaching party has not cured the breach within 30 days’ written notice to the breaching party, or 60 days if such breach cannot reasonably be cured within 30 days and such cure is able to be cured within 60 days and is being diligently pursued, as long as, with respect to that breach would entitle the non-breaching party not to complete the merger.

TABLE OF CONTENTS

In addition, Enterprise may terminate the merger agreement prior to obtaining the requisite First Choice shareholder approval, if:

•

First Choice has materially breached its covenants described above under “The Merger Agreement — No Solicitation” and such breach is not cured on or before the expiration of the fifth business day after the occurrence of such breach; or

•

the First Choice board makes a subsequent determination, as described above under “The Merger Agreement — First Choice Board’s Covenant to Recommend the Merger Agreement.”

In addition, First Choice may terminate the merger agreement:

•

by delivering written notice to Enterprise at any time during the five trading day period commencing on the determination date, if both of the following conditions are satisfied: (i) the Enterprise daily volume weighted average stock price for the 20 consecutive trading days ending on the trading day immediately preceding the fifth trading day prior to the closing of the merger, which is referred to as the triggering VWAP, is less than $39.704 per share; and (ii) the triggering VWAP underperforms the average closing price of a specified index of financial institution stocks during the 20 trading days ending on the trading day immediately preceding the fifth trading day prior to the closing of the merger by more than 20%. If First Choice elects to terminate the merger agreement in such instance, Enterprise may elect to reinstate the merger agreement by adjusting the exchange ratio to increase the stock consideration. If Enterprise makes such election to reinstate the merger agreement, then no termination will occur and the merger agreement will remain in effect according to its terms (except the stock consideration, which will have been adjusted); or

•

at any time prior to obtaining the requisite First Choice shareholder approval, if the First Choice board or a First Choice board committee makes a subsequent determination with respect to a superior proposal, so long as First Choice concludes that it must endorse a superior proposal (as defined in the merger agreement), provided that First Choice has complied with its obligations described above under “The Merger Agreement — No Solicitation.”

Termination Fee; Effect of Termination

If the merger agreement is terminated, it will become void and have no effect and the parties will be relieved of all obligations and liabilities, except that certain specified provisions of the merger agreement will survive. If the merger agreement is terminated because of a willful breach of a representation, warranty, covenant or agreement, the breaching party will not be relieved of liability for any breach giving rise to the termination, provided, however, if either party is required to pay the other the termination fee or liquidated damages described below (which shall be the recipient party’s sole and exclusive remedy against the other party), then such party will have no further obligations under the merger agreement.

The merger agreement also provides that First Choice must pay Enterprise a fee and reimburse expenses in certain situations. In particular, First Choice will pay Enterprise a fee of $16,800,000 in certain circumstances set forth in the merger agreement, including if:

•

Enterprise terminates the merger agreement because (i) First Choice has materially breached its covenants described under “The Merger Agreement — No Solicitation” and such breach is not cured on or before the expiration of the fifth business day after the occurrence of such breach, or (ii) the First Choice board makes a subsequent determination, as described above under “The Merger Agreement — First Choice Board’s Covenant to Recommend the Merger Agreement”; or

•

First Choice receives an acquisition proposal from a third party and the merger agreement is subsequently terminated by either Enterprise or First Choice under certain conditions, and prior to the twelve (12) month anniversary of the termination of the merger agreement First Choice enters into an agreement to engage in an acquisition transaction that relates to the acquisition proposal.

If the merger agreement is terminated by either party as a result of the other party’s breaches of its representations or warranties or material breaches of its covenants and agreements set forth in the merger agreement, and such breach would result in the closing conditions not being satisfied, then the non-terminating party will be required to pay the terminating party $1,500,000 as liquidated damages (provided that, if the

TABLE OF CONTENTS

termination fee described above is also payable, the payment of such liquidated damages shall reduce, on a dollar-for-dollar basis, the amount of the termination fee that would also be payable).

Certain Employee Matters

The merger agreement contains certain agreements of the parties with respect to various employee matters, which are described below.

Each person who is an employee of First Choice or FCB as of the effective time of the merger will become an employee of Enterprise or EB&T, whom we refer to as the continuing employees. Enterprise has agreed, for a period beginning on the closing date of the merger and ending on a specified harmonization date, to maintain the employment of each continuing employee on terms and conditions no less favorable, in the aggregate, to such continuing employee as those provided by First Choice or FCB immediately prior to the closing date of the merger.

With respect to any Enterprise benefit plan in which a continuing employee will participate, such continuing employee will receive prior service credit for purposes of vesting, eligibility, and benefit accrual; provided that such service will not be recognized to the extent (i) recognition will result in a duplication of benefits or (ii) such service was not recognized under the corresponding First Choice benefit plan.

With respect to any group health plan, Enterprise will waive or cause to be waived any waiting periods, evidence of insurability requirements or pre-existing condition limitations or similar limitations with respect to participation and coverage requirements applicable to continuing employees and credit each continuing employee for any co-payments and deductibles paid prior to the closing date of the merger in satisfying applicable deductible or out-of-pocket expense requirements.

With respect to severance benefits, Enterprise will credit the term of employment of any continuing employee who becomes entitled to severance benefits after closing with service credit relating to their service provided to First Choice and/or FCB prior to the effective time of the merger to the extent such service would have been recognized under First Choice’s severance plan as in effect immediately prior to the closing.

Expenses of the Merger

The merger agreement provides that each of First Choice and Enterprise will bear and pay all expenses incurred by it in connection with the transactions contemplated by the merger agreement, including fees and expenses of its own financial consultants, accountants and counsel.

Stock Exchange Listing

Enterprise has agreed to use its commercially reasonable efforts to list the Enterprise common stock to be issued in the merger on Nasdaq. It is a condition to the completion of the merger that those shares be approved for listing on Nasdaq, subject to official notice of issuance. Following the merger, Enterprise expects that its common stock will continue to trade on the Nasdaq Global Select Market under the symbol “EFSC.”

Restrictions on Resales by Affiliates

Enterprise has registered its shares of common stock to be issued in the merger with the SEC under the Securities Act. No restrictions on the sale or other transfer of shares of Enterprise common stock issued in the merger will be imposed solely as a result of the merger, except for restrictions on the transfer of shares of Enterprise common stock issued to any First Choice shareholder who is or becomes an “affiliate” of Enterprise for purposes of Rule 144 under the Securities Act. The term “affiliate” is defined in Rule 144 under the Securities Act as a person that directly, or indirectly through one or more intermediaries, controls, is controlled by, or is under common control with, Enterprise or the combined company, as the case may be, and generally includes executive officers, directors and stockholders beneficially owning 10% or more of Enterprise’s outstanding common stock.

TABLE OF CONTENTS

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

General. The following discussion addresses the material United States, or U.S., federal income tax consequences of the merger to U.S. holders (as defined below) of First Choice common stock. The discussion is based on the provisions of the Code, its legislative history, U.S. Treasury regulations, administrative rulings and judicial decisions, all as currently in effect as of the date hereof and all of which are subject to change (possibly with retroactive effect) and all of which are subject to differing interpretations. Tax considerations under foreign, state, or local tax laws, and under federal tax laws other than those pertaining to U.S. federal income tax are not addressed in this joint proxy statement/prospectus.

The following discussion neither binds the IRS nor precludes the IRS from adopting a position contrary to that expressed in this joint proxy statement/prospectus, and we cannot assure you that such contrary position could not be asserted successfully by the IRS or adopted by a court if the positions were litigated. We have not obtained, and do not intend to obtain, a ruling from the IRS with respect to the U.S. federal income tax consequences of the merger.

For purposes of this discussion, we use the term U.S. holder to mean a beneficial owner that is:

•

an individual citizen or resident of the United States;

•

a corporation (or other entity taxable as a corporation for U.S. federal income tax purposes) created or organized under the laws of the United States or any of its political subdivisions;

•

a trust that (i) is subject to the supervision of a court within the U.S. and the control of one or more U.S. persons or (ii) was in existence on August 20, 1996 and has a valid election in effect under applicable U.S. Treasury regulations to continue to be treated as a U.S. person for U.S. federal income tax purposes; or

•

an estate that is subject to U.S. federal income taxation on its income regardless of its source.

This discussion applies only to First Choice shareholders that hold their First Choice common stock as a capital asset within the meaning of Section 1221 of the Code (generally, property held for investment), and does not address all aspects of U.S. federal income taxation that may be relevant to a particular U.S. holder in light of his, her or its personal circumstances or to U.S. holders subject to special treatment under the U.S. federal income tax laws, including:

•

financial institutions;

•

pass-through entities and investors in pass-through entities;

•

persons liable for the alternative minimum tax;

•

insurance companies;

•

tax-exempt organizations;

•

dealers or brokers in securities, commodities or currencies;

•

traders in securities that elect to use a mark to market method of accounting;

•

persons that hold First Choice common stock as part of a straddle, hedge, constructive sale or conversion transaction or other risk reduction transaction;

•

regulated investment companies;

•

real estate investment trusts;

•

persons whose “functional currency” is not the U.S. dollar;

•

persons who are not citizens or residents of the United States;

•

U.S. expatriates;

•

retirement plans, individual retirement accounts, or other tax-deferred accounts;

•

mutual funds;

TABLE OF CONTENTS

•

shareholders who exercise dissenters’ rights, if applicable; and

•

shareholders who acquired their shares of First Choice common stock through the exercise of an employee stock option, as a restricted stock award, or otherwise as compensation.

If a partnership or other entity taxed as a partnership holds First Choice common stock, the tax treatment of a partner in the partnership will depend upon the status of the partner and the activities of the partner and partnership. Partnerships and partners in such a partnership should consult their tax advisors about the tax consequences of the merger to them.

The actual tax consequences of the merger to you may be complex and will depend on your specific situation and on factors that are not within our control. You should consult with your own tax advisor as to the tax consequences of the merger in your particular circumstances, including the applicability and effect of the alternative minimum tax and any state, local or foreign and other tax laws and of changes in those laws. In addition, to the extent that you recognize gain in the merger, you should consult with your own tax advisor with respect to the impact of the 3.8% Medicare tax on certain net investment income.

U.S. Federal Income Tax Consequences of the Merger. Based upon the facts and representations contained in the representation letters received from Enterprise and First Choice in connection with the filing of the registration statement on Form S-4 of which this joint proxy statement/prospectus is a part, it is the opinion of Holland & Knight and Duane Morris that the merger of First Choice with and into Enterprise will qualify as a reorganization within the meaning of Section 368(a) of the Code. Because the merger will qualify as a reorganization under Section 368(a) of the Code, the U.S. federal income tax consequences will be as follows:

•

no gain or loss will be recognized by Enterprise or First Choice as a result of the merger;

•

a U.S. holder of First Choice common stock who receives shares of Enterprise common stock and no cash consideration (other than in lieu of fractional shares) in exchange for all of his, her or its shares of First Choice common stock pursuant to the merger generally will not recognize gain or loss; provided that gain or loss may be recognized with respect to cash received in lieu of fractional shares (see “Cash Received in Lieu of a Fractional Share” below);

•

a U.S. holder of First Choice common stock who receives cash in lieu of a fractional share of Enterprise common stock will be treated as having received the fractional share pursuant to the merger and then as having exchanged the fractional share for cash in a redemption by Enterprise. This deemed redemption generally will be treated as a sale or exchange, and as a result, such U.S. holder will generally recognize gain or loss equal to the difference between the amount of cash received and the basis in his or her fractional share interest as set forth below. Except as described below, this gain or loss will generally be capital gain or loss, and will be long-term capital gain or loss if, as of the effective date of the merger, such U.S.holder’s holding period for such shares is greater than one (1) year;

•

the aggregate basis of the Enterprise common stock received in the merger by a U.S. holder of First Choice common stock (including any fractional shares of Enterprise common stock deemed received and exchanged for cash) will be the same as the aggregate basis of the First Choice common stock for which it is exchanged. If you acquired different blocks of shares of First Choice common stock at different times or different prices, the basis of each block of Enterprise common stock you will receive will be determined separately for each block depending on the basis of the blocks of First Choice common stock exchanged for such block of Enterprise common stock;

•

the holding period of Enterprise common stock received in exchange for shares of First Choice common stock (including any fractional shares of Enterprise common stock deemed received and exchanged for cash) will include the holding period of the First Choice common stock for which it is exchanged. If you acquired different blocks of shares of First Choice common stock at different times or different prices, the holding period of each block of Enterprise common stock you will receive will be determined separately for each block depending on the holding period of the blocks of First Choice common stock exchanged for such block of Enterprise common stock; and

•

for U.S. holders of First Choice common stock that are non-corporate holders, long-term capital gain generally will be taxed at a U.S. federal income tax rate that is lower than the rate for ordinary

TABLE OF CONTENTS

income or for short-term capital gains. In addition, net investment income of certain high-income taxpayers may also be subject to an additional 3.8% tax (i.e., the net investment income tax). The deductibility of capital losses is subject to limitations.

It is a condition to First Choice’s obligation to complete the merger that First Choice receives a written opinion of its counsel, Duane Morris, dated as of the closing date, to the effect that the merger of First Choice with and into Enterprise will qualify as a reorganization within the meaning of Section 368(a) of the Code. It is a condition to Enterprise’s obligation to complete the merger that Enterprise receives an opinion of its counsel, Holland & Knight, dated as of the closing date, to the effect that the merger of First Choice with and into Enterprise will qualify as a reorganization within the meaning of Section 368(a) of the Code. These opinions will be based on the assumption that the merger will be completed in the manner set forth in the merger agreement and the registration statement on Form S-4 of which this joint proxy statement/prospectus is a part, and on representation letters provided by Enterprise and First Choice to be delivered at the time of the closing. Those opinions will also be based on the assumption that the representations found in the representation letters are, as of the effective time, true and complete without qualification and that the representation letters are executed by appropriate and authorized officers of Enterprise and First Choice. If any of the assumptions or representations upon which such opinions are based is inconsistent with the actual facts with respect to the merger, the U.S. federal income tax consequences of the merger could be adversely affected.

In addition, neither of the tax opinions given in connection with the merger or in connection with the filing of the registration statement on Form S-4 of which this joint proxy statement/prospectus is a part will be binding on the IRS or any court. Neither Enterprise nor First Choice intends to request any ruling from the IRS or any foreign state or local tax authorities as to any tax issues in connection with the merger and, consequently, there is no guarantee that the IRS will treat the merger as a “reorganization” within the meaning of Section 368(a) of the Code or that a court would not sustain a position to the contrary to any of the positions set forth herein. If the merger does not qualify as a “reorganization” within the meaning of Section 368(a) of the Code, the transaction would be treated as a fully taxable transaction on which gain or loss would be recognized in full. In addition, penalties and interest could be imposed on any resulting tax deficiency. Accordingly, each U.S. holder of First Choice common stock should consult her or his tax advisor with respect to the particular tax consequences of the merger to such holder.

Backup Withholding and Information Reporting. Payments of cash in lieu of a fractional share of Enterprise common stock to a U.S. holder of First Choice common stock pursuant to the merger are subject to information reporting and may, under certain circumstances, be subject to backup withholding at a rate 24%, unless such shareholder provides Enterprise with its taxpayer identification number and otherwise complies with the backup withholding rules. Any amounts withheld from payments to a U.S. holder of First Choice common stock under the backup withholding rules are not additional tax and generally will be allowed as a refund or credit against such U.S. holder’s U.S. federal income tax liability, if any; provided that such U.S. holder timely furnishes the required information to the IRS.

A U.S. holder of First Choice common stock who receives Enterprise common stock as a result of the merger will be required to retain records pertaining to the merger. Each U.S. holder of First Choice common stock who is required to file a U.S. federal income tax return and who is a “significant holder” that receives Enterprise common stock in the merger will be required to file a statement with such U.S. federal income tax return in accordance with U.S. Treasury Regulations Section 1.368-3 setting forth information regarding the parties to the merger, the date of the merger, such holder’s basis in the First Choice common stock surrendered and the fair market value of Enterprise common stock and cash received in the merger. A “significant holder” is a holder of First Choice common stock who, immediately before the merger, owned (i) at least 5% (by vote or value) of the outstanding stock of First Choice or (ii) securities of First Choice with a basis for U.S. federal income tax purposes of at least $1 million.

TABLE OF CONTENTS

COMPARISON OF STOCKHOLDER AND SHAREHOLDER RIGHTS

When the merger becomes effective, shareholders of First Choice will become stockholders of Enterprise. Enterprise is a Delaware corporation and the rights of Enterprise stockholders are governed by the Delaware General Corporation Law, or the DGCL, as well as Enterprise’s certificate of incorporation, as amended, and Enterprise’s amended and restated bylaws. First Choice is incorporated under the laws of the State of California and the rights of First Choice shareholders are governed by the California General Corporation Law, or the CGCL, as well as First Choice’s articles of incorporation and First Choice’s bylaws.

After the merger, as Enterprise stockholders, the rights of former First Choice shareholders will be governed by Enterprise’s certificate of incorporation, as amended, Enterprise’s amended and restated bylaws, and the DGCL. The following discussion summarizes the material differences between the rights of First Choice shareholders and the rights of Enterprise stockholders. The summary does not purport to be a complete statement of the provisions affecting, and differences between, the rights of Enterprise stockholders and of First Choice shareholders. Rather, the summary is intended to provide a general overview of the differences in shareholders’ rights under the governing corporate instruments of Enterprise and First Choice, and other known material differences. We urge you to read Enterprise’s certificate of incorporation, as amended, Enterprise’s amended and restated bylaws, First Choice’s articles of incorporation, First Choice’s bylaws, and the DGCL and the CGCL carefully and in their entirety.

Authorized Capital Stock

Enterprise

Enterprise’s authorized capital stock consists of 45,000,000 shares of Enterprise common stock, $0.01 par value per share, and 5,000,000 shares of Enterprise preferred stock, $0.01 par value per share. If the Enterprise charter amendment proposal is approved by Enterprise stockholders, the number of authorized shares of Enterprise common stock will be increased to 75,000,000 shares. The Enterprise charter amendment proposal does not affect the number of authorized shares of Enterprise preferred stock. A copy of the Enterprise charter amendment proposal is attached to this joint proxy statement/prospectus as Appendix C.

As of , 2021, shares of Enterprise common stock were outstanding and no shares of Enterprise preferred stock were outstanding. Enterprise has no present plans to issue any shares of Enterprise preferred stock.

First Choice

First Choice’s authorized capital stock consists of 100,000,000 shares of First Choice common stock, no par value per share, and 100,000,000 shares of First Choice serial preferred stock, no par value per share.

As of , 2021, shares of First Choice common stock were outstanding and no shares of First Choice serial preferred stock were outstanding.

Size of the Board of Directors

Enterprise

Enterprise’s amended and restated bylaws provide that the size of the Enterprise board of directors may be fixed from time to time by the board of directors. There are currently 12 directors on Enterprise’s board of directors. Enterprise’s board of directors has resolved to take all action necessary to give effect to the appointment of Peter Hui, the Chairman of the Board of First Choice and FCB, to the board of directors of Enterprise as of the effective time of the merger in accordance with the merger agreement (see “The Merger Agreement — Management after the Merger” beginning on page ), including by increasing the size of the board by one member in the event there are no vacancies on the board to permit such appointment.

First Choice

First Choice’s bylaws provide that the authorized number of directors shall be not less than seven and not more than 13. The size of First Choice’s board of directors is currently eight and may be fixed from

104

TABLE OF CONTENTS

time to time within such range by First Choice’s board of directors or shareholders. The minimum and maximum number of directors may be changed, or a definite number may be fixed without provision for an indefinite number, by a duly adopted amendment to First Choice’s articles of incorporation or by an amendment to First Choice’s bylaws duly adopted by the vote or written consent of holders of a majority of the outstanding shares entitled to vote; provided, however, that an amendment reducing the fixed number or the minimum number of directors to a number less than five cannot be adopted if the votes cast against its adoption at a meeting, or the shares not consenting in the case of an action by written consent, are equal to more than 16 2∕3% of the outstanding shares entitled to vote thereon.

Class and Election of Directors

Enterprise

Enterprise’s amended and restated bylaws provide that Enterprise’s board of directors consists of one class of directors. Directors are elected by the Enterprise stockholders each year at the annual meeting of stockholders and hold office until each director’s successor has been duly elected and qualified or until a director’s earlier death, resignation or removal.

First Choice

First Choice’s bylaws provide that First Choice’s board of directors consists of one class of directors. Directors are elected by the First Choice shareholders each year at the annual meeting of shareholders and hold office until the next annual meeting and until a successor has been elected and qualified or until the director’s earlier death, resignation, disqualification or removal.

Removal of Directors

Enterprise

Under Enterprise’s amended and restated bylaws, any director may be removed with or without cause by a majority of the holders of shares entitled to vote at an election of directors.

First Choice

Under First Choice’s bylaws, any or all of the directors can be removed with or without cause by a vote of the shareholders entitled to elect them.

However, the First Choice bylaws provide that no director may be removed by the shareholders (unless the entire board is removed) if the votes cast against removal would be sufficient to elect the director if cumulatively voted at an election of all of the directors (as of the date of the director’s most recent election) at which the same total number of votes were cast. The First Choice bylaws also provide that the board of directors may declare a vacancy for any director who is declared of unsound mind by an order of court or convicted of a felony.

Filling Vacancies on the Board of Directors

Enterprise

Under Enterprise’s amended and restated bylaws, any vacancy occurring in Enterprise’s board of directors will be filled by a majority vote of the remaining directors. Directors so chosen will serve for a term expiring at the next annual meeting of stockholders and until such director’s successor has been duly elected and qualified.

First Choice

Under First Choice’s bylaws, a vacancy occurring in First Choice’s board of directors (other than vacancies created by removal of a director) may be filled by the board of directors in accordance with Section 305 of the CGCL, which provides that except for a vacancy created by the removal of a director,

105

TABLE OF CONTENTS

vacancies on the board of directors may be filled by approval of the board of directors by (i) unanimous written consent of the directors then in office, (ii) the affirmative vote of a majority of the directors then in office, or (iii) a sole remaining director. Under Section 305 of the CGCL, a vacancy occurring in the board by reason of removal of a director may be filled only by approval of the shareholders. A director appointed to fill a vacancy will serve until the next annual meeting of the shareholders and until a successor has been elected and qualified (or until the director’s earlier death, resignation, disqualification, or removal). First Choice’s bylaws further provide that the shareholders may elect a director at any time to fill any vacancy not filled by the board of directors.

Shareholder Nominations and Proposals

Enterprise

Enterprise’s amended and restated bylaws establish procedures that stockholders must follow to nominate persons for election to Enterprise’s board of directors. The stockholder making the nomination must deliver written notice to Enterprise’s secretary between 90 and 120 days prior to the first anniversary of the preceding year’s annual meeting (if an annual meeting) or prior to the date of the meeting at which directors will be elected (if a special meeting). If the date of the annual meeting is more than 30 days before or more than 60 days after the first anniversary of the preceding year’s annual meeting, then the notice must be delivered between 90 and 120 days prior to the date of such annual meeting. However, if the first public announcement of the date of such annual or special meeting is less than 100 days prior to its date, nominations must be provided by the 10th day following the day on which the public announcement of the date of such meeting was first made. Any person nominated must be a stockholder of record at the time the board of directors gives notice of the annual or special meeting and must be entitled to vote at such annual meeting. The nomination notice must set forth information concerning the nominee, the nominating shareholder and the other information specified in Enterprise’s amended and restated bylaws.

Enterprise’s amended and restated bylaws provide that any proposal by a stockholder of other business to be properly brought before the annual meeting of stockholders must be delivered to Enterprise’s secretary within the same time frame as stockholder nominations for directors at an annual meeting, as described above. Each such notice shall set forth information concerning the proposal, the proposing stockholder and the other information specified in Enterprise’s amended and restated bylaws.

The chairman of the meeting has the power to determine whether a director nomination or any other proposed business to be brought before a meeting was made or proposed in accordance with Enterprise’s amended and restated bylaws.

First Choice

First Choice’s bylaws establish procedures that shareholders must follow to nominate persons for election to First Choice’s board of directors. The shareholder making the nomination must deliver written notice of the proposing shareholder’s nomination or proposal, either by personal delivery or by United States mail to First Choice’s secretary no earlier than 120 days and no later than 90 days before the date of the annual meeting (unless the annual meeting date is not within 30 days of the anniversary of the previous year’s, then notice must be received not later than 10 days following the public announcement of the date of the annual meeting). The nomination notice must set forth information concerning the nominee, the nominating shareholder and the other information specified in First Choice’s bylaws. First Choice’s bylaws provide that any proposal by a stockholder of other business to be properly brought before the annual meeting must be delivered to First Choice’s secretary within the same time frame as shareholder nominations for directors at an annual meeting, as described above. Each such notice shall set forth information concerning the proposal, the proposing shareholder and the other information specified in First Choice’s amended and restated bylaws. A copy of this information is required to be set forth in the notice to shareholders of any meeting at which directors are to be elected.

Calling Special Meetings of Shareholders

Enterprise

A special meeting of stockholders may be called by Enterprise’s board of directors pursuant to a resolution approved by a majority of all directors, Enterprise’s chairman of the board of directors,

106

TABLE OF CONTENTS

Enterprise’s chief executive officer or upon a written request to the Enterprise’s secretary of the holders of at least 50% of the voting power of all of Enterprise’s outstanding stock entitled to vote.

First Choice

A special meeting of shareholders may be called by the board of directors, the chair of the board of directors, First Choice’s president, or by one or more shareholders holding shares in the aggregate entitled to cast not less than 10% of the votes at any such meeting.

Voting Rights

Enterprise

Each holder of Enterprise common stock is entitled to one vote for each share held by him, her or it. All director elections are determined by a plurality of the votes cast and, except as otherwise required by law, Enterprise’s certificate of incorporation, as amended, or amended and restated bylaws, all other matters are determined by a majority of the votes cast. Enterprise’s certificate of incorporation, as amended, provides that holders of Enterprise’s common stock will have the exclusive right to vote for the election of directors and for all other purposes. Holders of Enterprise common stock do not have the right to cumulate votes in the election of directors.

First Choice

Each holder of First Choice stock (regardless of class or series) is entitled to one vote for each share held by him, her or it, subject to any special voting rights provided in First Choice’s articles of incorporation, if any. Shareholders entitled to vote on any matter may vote part of their shares in favor of a proposal and refrain from voting the remaining shares, or, other than in elections of directors, vote the remaining shares against the proposal. If a shareholder fails to specify the number of shares the shareholder is voting affirmatively, the shareholder will be deemed to have affirmatively voted all shares the shareholder is entitled to vote. In any election of directors, the shareholders of First Choice shall (subject to satisfaction of all statutory conditions precedent to exercise such rights) have the right to cumulate the number of votes equal to the number of directors to be directed multiplied by the number of votes to which such shareholder’s shares are entitled, and distribute those votes among one or more candidates. Shareholders of First Choice can exercise this right by giving written notice of intent to cumulate those votes to any officer of First Choice before the meeting or the presiding officer at the meeting at any time before the election of directors. Per the First Choice bylaws, the directors receiving the highest number of votes of the shares entitled to vote in the election, up to the number of director positions to be filled, shall be elected.

In general, subject to First Choice’s articles of incorporation and the CGCL, the affirmative vote of a majority of the shares represented at a meeting at which a quorum is present shall be the act of the shareholders.

Notice of Shareholder Meetings

Enterprise

Enterprise’s amended and restated bylaws provide that Enterprise must notify stockholders between 10 and 60 days before any stockholder meeting of the place, date and hour of the meeting and the general nature of the business to be considered at the meeting. Such notice shall also include the means of remote communications, if any, by which stockholders and proxy holders may be deemed to be present and the record date for determining the stockholders entitled to vote (if such date is different from the record date for determining stockholders entitled to notice of the meeting).

First Choice

First Choice’s bylaws provide that First Choice must provide written notice to shareholders not less than 10 days (or, if sent by third class mail, 30 days) and not more than 60 days before a meeting of shareholders of the place, day, and hour of the meeting. In the case of an annual meeting, the notice must

107

TABLE OF CONTENTS

state the matters which the board of directors intends to present to the shareholders for action; provided, however, that unless the notice of the meeting sets forth the general nature of any proposal to, among other things included in First Choice’s bylaws, approve a merger, no such proposal can be approved at an annual meeting. In the case of a special meeting, the notice is required to state the general nature of the business to be transacted, and if directors are to be elected, the notice shall include the names of the nominees. If remote participation in a meeting is authorized by First Choice’s board of directors, the notice must state the means of electronic transmission by and to First Choice or electronic video screen communication by which the shareholders of First Choice may participate.

Quorum for Meetings of Shareholders

Enterprise

Enterprise’s amended and restated bylaws provide that, except as otherwise provided by law or Enterprise’s certificate of incorporation, as amended, the holders of a majority of the outstanding shares of stock entitled to vote at any meeting of stockholders, present in person or by proxy, shall constitute a quorum.

First Choice

First Choice’s bylaws provide that the presence in person or by proxy of the holders of a majority of the shares entitled to vote will constitute a quorum.

Shareholder Actions by Written Consent

Enterprise

The DGCL allows action by written consent by the holders of the minimum number of votes that would be needed to approve such a matter at an annual or special meeting of stockholders if all shares entitled to vote thereat were present and voted, unless the right to act by written consent is denied in the corporation’s certificate of incorporation. Enterprise’s amended and restated bylaws reaffirm the right to act by written consent, but require that any written action be delivered to Enterprise at its registered office, at its principal place of business, or to an officer or agent of Enterprise that has custody of the minute books in which proceedings of stockholders are recorded.

First Choice

The CGCL provides that unless otherwise provided in the articles of incorporation, any action that may be taken at an annual or special meeting may be taken by written consent by the holders of the minimum number of votes that would be needed to approve such action at a meeting at which all shares entitled to vote thereon were present and voted. First Choice’s articles do no limit the ability of First Choice shareholders to act by written consent. First Choice’s bylaws confirm this right, and further add that unless the consents of all shareholders entitled to vote have been solicited in writing, notice shall be given of such action to all shareholders entitled to vote who did not consent in writing to such action. First Choice’s bylaws further provide that First Choice’s shareholders may elect directors by written consent only if such consent is unanimously given by all shareholders entitled to vote (except that action taken by shareholders to fill one or more vacancies on the board other than a vacancy created by the removal of a director, may be taken by written consent of a majority of the outstanding shares entitled to vote).

Votes on Mergers, Consolidations, Sales or Leases of Assets and Certain Other Transactions

Enterprise

The DGCL provides that a merger or sale of all or substantially all of the assets of a Delaware corporation shall be approved by the affirmative vote of the holders of a majority of the outstanding shares entitled to vote on the merger or sale. Neither Enterprise’s certificate of incorporation, as amended, or amended and restated bylaws provide a different standard regarding the vote required to approve a merger or sale of all or substantially all of the assets of Enterprise.

108

TABLE OF CONTENTS

First Choice

The CGCL provides that a merger must be approved by a vote of a majority of the outstanding shares entitled to vote. In the case of a California target in a merger transaction, the CGCL requires this vote for each class of stock, whether or not that class otherwise has voting rights.

Shareholders’ Rights of Dissent and Appraisal

Enterprise

Under the DGCL, stockholders are generally entitled to dissent from a merger or consolidation and obtain payment of the fair value of their shares. However, the DGCL provides that appraisal rights are not available with respect to any class or series of stock that is either listed on a national securities exchange or held of record by more than 2,000 holders, unless, under the terms of the transaction, holders are required to accept any consideration that is different from the consideration to be provided to any other holder of such class or series of stock or anything other than shares of publicly traded stock of the acquirer and/or cash in lieu of fractional shares.

First Choice

Under the CGCL, shareholders are generally entitled to dissent from a merger or consolidation and, in certain circumstances, obtain payment of the fair value of their shares when a merger or consolidation occurs. However, the CGCL provides that appraisal rights are not available where the dissenting shares are listed on a national securities exchange certified by the California Financial Protection and Innovation Commissioner and the merger consideration consists only of shares that are listed on a national securities exchange certified by the California Financial Protection and Innovation Commissioner.

Transactions with Interested Persons

Enterprise

The DGCL prohibits a corporation from engaging in any business combination with an interested stockholder (defined as a 15% stockholder) for a period of three years after the date that stockholder became an interested stockholder, unless (i) before that date, the board of directors of the corporation approved the business combination or the transaction in which the stockholder became an interested stockholder, (ii) upon completion of the transaction that resulted in the stockholder becoming an interested stockholder, the stockholder owned at least 85% of the outstanding voting stock (excluding shares owned by directors, officers and certain employee stock ownership plans), or (iii) on or after the date the stockholder became an interested stockholder, the business combination received the approval of both the corporation’s directors and holders of two-thirds of the outstanding voting shares not owned by the interested stockholder voted at a meeting and not by written consent. A Delaware corporation may opt out of this provision through an amendment to its certificate of incorporation or bylaws adopted by a majority of the outstanding voting shares. Enterprise has not opted out of this provision.

First Choice

Under the CGCL, a contract or other transaction between a corporation and one or more of its directors, or between a corporation and any corporation, firm or association in which one or more of its directors has a material financial interest, is not void or voidable because such director or directors or such other corporation, firm or association are parties or because such director or directors are present at the meeting of the board or a committee thereof which authorizes, approves or ratifies the contract or transaction, if (i) the material facts as to the transaction and as to such director’s interest are fully disclosed or known to the shareholders and such contract or transaction is approved in good faith by the affirmative vote of a majority of the shares represented and voting at a duly held meeting at which a quorum is present (or by written consent of shareholders having not less than the minimum number of votes necessary to authorize such action at a meeting at which all shares entitled to vote thereon were present or voted), with the shares owned by the interested director or directors not being entitled to vote thereon, (ii) the material facts as to the transaction and as to such director’s interest are fully disclosed or known to the board or

109

TABLE OF CONTENTS

committee, and the board or committee authorizes, approves or ratifies the contract or transaction in good faith by a vote sufficient without counting the vote of the interested director or directors and the contract or transaction is just and reasonable as to the corporation at the time it is authorized, approved or ratified, or (iii) as to contracts or transactions not approved as provided in clauses (i) or (ii), the person asserting the validity of the contract or transaction sustains the burden of proving that the contract or transaction was just and reasonable as to the corporation at the time it was authorized, approved or ratified.

The First Choice bylaws provide that notice of any meeting of the shareholders shall specify the general nature of any proposal if such proposal relates to the approval or ratification of a transaction in which a director has a material financial interest under the CGCL.

The CGCL further provides that if a written proposal for approval of a reorganization is made to some or all of a corporation’s shareholders by an interested party, an affirmative opinion in writing as to the fairness of the consideration to the shareholders of that corporation shall be delivered. If a shareholders’ meeting is to be held to vote on approval of the transaction, the opinion shall be delivered to the shareholders with the notice of the meeting.

Shareholders Rights Plans

Enterprise

Enterprise does not have a stockholder rights plan in place.

First Choice

First Choice does not have a shareholder rights plan in place.

Dividends

Enterprise

Under the DGCL, a corporation may pay dividends to the extent of its surplus, and, if no surplus is available, dividends may be paid to the extent of its net profits for the current and/or preceding fiscal year. Dividends may not be declared, however, if the corporation’s capital has been diminished to an amount less than the aggregate amount of all capital represented by the issued and outstanding stock of all classes having a preference upon the distribution of assets. Enterprise’s amended and restated bylaws provide that dividends, if any, may be declared by Enterprise’s board of directors.

First Choice

Under the CGCL, a corporation cannot make any distribution to its shareholders unless its board of directors has determined in good faith either (i) the amount of retained earnings of the corporation immediately prior to the distribution equals or exceeds the sum of (a) the amount of the proposed distribution plus (b) the preferential dividends arrears amount; or (ii) immediately after the distribution, the value of the corporation’s assets would equal or exceed the sum of its total liabilities, plus any preferential rights amount.

Indemnification of Directors and Officers

Enterprise

The DGCL provides that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that he or she is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action,

110

TABLE OF CONTENTS

suit or proceeding if such person acted in good faith and in a manner such person 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. A similar standard is applicable in the case of derivative actions, except that indemnification extends only to expenses (including attorneys’ fees) incurred in connection with the defense or settlement of such action, and the statute requires court approval before there can be any indemnification where the person seeking indemnification has been found liable to the corporation.

The DGCL provides that any indemnification must be made by the corporation only as authorized in the specific case upon a determination that indemnification is proper in the circumstances because the person has met the applicable standard of conduct. Such determination must be made, with respect to a person who is a director or officer at the time of such determination, (i) by a majority vote of the directors who are not parties to the action, suit or proceeding, even though less than a quorum, (ii) by a committee of such directors designated by majority vote of such directors, even though less than a quorum, (iii) if there are no such directors, or if such directors so direct, by independent legal counsel in a written opinion, or (iv) by the stockholders.

The DGCL provides that it is not exclusive of other indemnification that may be granted by a corporation’s bylaws, disinterested director vote, stockholder vote, agreement or otherwise.

Enterprise’s certificate of incorporation, as amended, provides that Enterprise shall indemnify all of its directors and officers to the fullest extent permitted by the DGCL and as set forth in the bylaws. Enterprise’s amended and restated bylaws provide that Enterprise will indemnify any person who was or is a party or is threatened to be made a party to or is otherwise involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative by reason of the fact that such person is or was a director or officer of Enterprise or by reason of the fact that such person is or was serving at the request of Enterprise as a director, officer or trustee of another corporation, partnership, joint venture, trust, or other enterprise, against expense, liability and loss (including attorneys’ fees, judgments, fines, excise taxes or penalties and amounts paid or to be paid in settlement) reasonably incurred by such person in connection with such action, suit, or proceeding, but in each case only if and to the extent permitted under the DGCL. Indemnification under this provision will not be provided to any director, officer or representative that initiates such proceeding, unless such proceeding was authorized or consented to by the board of directors.

In addition, as permitted by the DGCL, Enterprise’s certificate of incorporation, as amended, provides that directors will have no personal liability to Enterprise or its stockholders for monetary damages for breach of fiduciary duty as a director, except: (i) for any breach of the director’s duty of loyalty to Enterprise or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) the unlawful payment of dividends or unlawful stock purchase or redemption; or (iv) for any transaction from which the director derived an improper personal benefit.

First Choice

The CGCL provides that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation to procure a judgment in its favor) by reason of the fact that he or she is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise (“agents”), against expenses (including attorneys’ fees), judgments, fines, settlements, and other amounts actually and reasonably incurred in connection with the proceeding if that person acted in good faith and in a manner the person reasonably believed to be in the best interests of the corporation and, in the case of a criminal proceeding, had no reasonable cause to believe the conduct of the person was unlawful. A similar standard is applicable in the case of actions by or in the right of the corporation, except that indemnification extends only to expenses actually and reasonably incurred in connection with the defense or settlement of such action.

The CGCL provides that any indemnification must be made by the corporation only as authorized in the specific case upon a determination that indemnification is proper in the circumstances because the person has met the applicable standard of conduct. Such determination must be made (i) by a majority vote of a

111

TABLE OF CONTENTS

quorum consisting of directors who are not parties to such proceeding, (ii) if such a quorum of directors is not obtainable, by independent legal counsel in a written opinion, (iii) by the affirmative vote of a majority of the shares represented and voting at a duly held meeting at which a quorum is present, with the shares owned by the person to be indemnified not being entitled to vote thereon (or by written consent of shareholders having not less than the minimum number of votes necessary to authorize such action at a meeting at which all shares entitled to vote thereon were present or voted), or (iv) by the court in which the proceeding is or was pending upon application made by the corporation or the person to be indemnified or the attorney or other person rendering services in connection with the defense, whether or not the application by the person to be indemnified, attorney or other person is opposed by the corporation.

The CGCL provides that it is not exclusive of other indemnification that may be granted by a corporation’s bylaws, disinterested director vote, shareholder vote, agreement or otherwise, to the extent the additional rights to indemnification are authorized in the articles of the corporation.

The CGCL permits a corporation to include in its articles of incorporation a provision eliminating or limiting the personal liability of directors to the corporation and the corporation’s shareholders for money damages, except for liability resulting from: (i) acts or omissions that involve intentional misconduct or a knowing and culpable violation of law; (ii) acts or omissions that a director believes to be contrary to the best interests of the corporation or its shareholders or that involve the absence of good faith on the part of the director; (iii) any transaction from which a director derived an improper personal benefit; (iv) acts or omissions that show a reckless disregard for the director’s duty to the corporation or its shareholders in circumstances in which the director was aware, or should have been aware, in the ordinary course of performing a director’s duties, of a risk of serious injury to the corporation or its shareholders; (v) acts or omissions that constitute an unexcused pattern of inattention that amounts to an abdication of the director’s duty to the corporation or its shareholders; (vi) acts arising from an interested director transaction listed under Section 310 of the CGCL; or (vii) acts arising from the approval of specific corporate action listed under Section 316 of the CGCL. The CGCL further provides that no such provision shall eliminate or limit the liability of a director for any act or omission occurring prior to the date when the provision becomes effective, and no such provision shall eliminate or limit the liability of an officer for any act or omission as an officer, notwithstanding that the officer is also a director or that his or her actions, if negligent or improper, have been ratified by the directors. As permitted by the CGCL, First Choice’s articles of incorporation provide that the liability of a director for monetary damages will be eliminated to the fullest extent permissible under California law.

The CGCL does not allow a corporation to indemnify its agents for: (i) any claim, issue or matter as to which the person has been adjudged to be liable to the corporation in the performance of that person’s duty to the corporation and its shareholders, unless and only to the extent that the court in which the proceeding is or was pending will determine upon application that, in view of all the circumstances of the case, the person is fairly and reasonably entitled to indemnity for expenses and then only to the extent that the court determines; (ii) any amounts paid in settling or otherwise disposing of a pending action without court approval; or (iii) any expenses incurred in defending a pending action which is settled or otherwise disposed of without court approval. The CGCL provides that to the extent that an agent of a corporation has been successful on the merits in defense of any related proceeding or in defense of any claim, issue, or matter therein, the agent will be indemnified against expenses actually and reasonably incurred by the agent.

First Choice’s articles of incorporation provide for the indemnification of its agents for breach of duty to First Choice and its shareholders through a bylaw provision, agreements with agents, or otherwise, in excess of the indemnification otherwise permitted by the CGCL, subject to the limits on excess indemnification under the CGCL. First Choice’s bylaws provide for indemnification of (i) any agent of First Choice against expenses (including reasonable attorney’s fees) actually and reasonably incurred in defense of any proceeding in which the agent was, is, or is threatened to be made a party by reason of being or having been an agent of First Choice, to the extent that the agent is successful on the merits in the defense and First Choice has the power to advance to such agent expenses incurred in defending any proceeding upon receipt of an undertaking by such agent to repay such amounts if the agent is not entitled to be indemnified for such amounts and (ii) any person who was, is, or is threatened to be made a party to any proceeding by or in the right of First Choice to procure a judgement in its favor by reason of being or having been an agent of First Choice, against expenses, including reasonable attorney’s fees, actually and reasonably incurred in

112

TABLE OF CONTENTS

defense or settlement of such proceeding, if the person acted in good faith and in a manner the person believed to be in the best interests of First Choice and its shareholders.

With respect to losses, First Choice’s bylaws provide for indemnification of any person who was, is or is threatened to be made a party to any proceeding (other than an action by or in the right of First Choice) by reason of being or having been an agent of First Choice, against expenses, including reasonable attorney’s fees, judgements, fines, settlements and other amounts actually and reasonable incurred in connection with the proceeding if the person (i) acted in good faith and in a manner the person believed to be in the best interests of First Choice and the shareholders and (ii) had no reasonable cause to believe the conduct of the person was unlawful (in the case of a criminal proceeding).

The indemnification and advancement of expenses provided for by First Choice’s bylaws is not exclusive of any other rights which any director or officer may be entitled by applicable law, First Choice’s articles of incorporation, action or resolution of the shareholders or disinterested directors, or any agreement with First Choice.

Amendments to Certificate or Articles of Incorporation and Bylaws

Enterprise

Under the DGCL, an amendment to Enterprise’s certificate of incorporation requires (i) the approval of its board of directors, (ii) the approval of the holders of a majority of the outstanding stock entitled to vote upon the proposed amendment and (iii) the approval of the holders of a majority of the outstanding stock of each class entitled to vote thereon as a class.

Enterprise’s amended and restated bylaws provide that the bylaws may be amended or repealed by (i) the approval of the holders of a majority of the outstanding stock entitled to vote at any annual or special meeting of stockholders, or (ii) the action of the Enterprise board of directors at any regular or special meeting.

First Choice

Under the CGCL, amendments to a corporation’s articles of incorporation may be adopted if approved by the board of directors and the outstanding shares.

First Choice’s bylaws provide that the bylaws may be amended or repealed, and new bylaws may be adopted (i) by the affirmative vote of a majority of the outstanding shares entitled to vote, or by the written assent of the shareholders entitled to vote, or (ii) except for a bylaw or amendment changing the authorized number of directors, by the board of directors, subject to the rights of First Choice’s shareholders.

DEADLINES FOR SUBMITTING STOCKHOLDER OR SHAREHOLDER PROPOSALS

Enterprise

Enterprise will hold its 2022 annual meeting of stockholders, or the 2022 Enterprise annual meeting, regardless of whether the merger has been completed.

Pursuant to Rule 14a-8 of the Exchange Act, in order for a stockholder proposal for the Enterprise 2022 annual meeting to be eligible for inclusion in Enterprise’s proxy statement, Enterprise must receive the proposal at its principal offices on or before November 17, 2021, which is 120 days prior to the anniversary date that Enterprise’s proxy statement was released to its stockholders for its 2021 annual meeting. An Enterprise stockholder must provide its proposal to Enterprise in writing, and it must comply with the requirements of Rule 14a-8 of the Exchange Act.

In addition, Enterprise’s amended and restated bylaws state that no business may be brought before an annual meeting of stockholders unless it is specified in the notice of the meeting or is otherwise brought before the meeting by the board of directors or by a stockholder of record entitled to vote who has delivered notice to Enterprise’s Secretary (containing the information specified in Enterprise’s amended and restated bylaws) no earlier than the 120 days and no later than 90 days prior to the first anniversary of the preceding years annual meeting. These advance notice procedures are separate from the requirements that a stockholder must meet in order to have a stockholder proposal included in Enterprise’s proxy statement pursuant to Rule 14a-8 of the Exchange Act. An Enterprise stockholder wishing to submit a proposal for consideration at the Enterprise 2022 annual meeting should do so no earlier than December 29, 2021 and no later than January 28, 2022.

First Choice does not anticipate holding a 2021 annual meeting of First Choice shareholders if the merger is completed as currently expected.

114

TABLE OF CONTENTS

proposals for other business intended to be presented at First Choice’s next annual meeting must be submitted to First Choice as set forth below.

Pursuant to Rule 14a-8 of the Exchange Act, and because the 2021 annual meeting, if held, will be delayed more than 30 days from the date of the 2020 annual meeting, in order for a shareholder proposal for the First Choice 2021 annual meeting to be eligible for inclusion in First Choice’s proxy statement, First Choice must have received the proposal at its principal offices a reasonable time before First Choice begins to print and send its proxy materials. A First Choice shareholder must provide its proposal to First Choice in writing, and it must comply with the requirements of Rule 14a-8 of the Exchange Act.

In addition, First Choice’s bylaws provide that for business (including director nominations) to be properly brought before an annual meeting by a shareholder, where the annual meeting is delayed by more than 30 days from the date of the previous year’s annual meeting, the shareholder or shareholders of record intending to propose the business must deliver written notice of the nomination or proposal, either by personal delivery or by United States mail, to First Choice’s Secretary not later than 10 days following the public announcement of the date of the annual meeting. These advance notice procedures are separate from the requirements that a shareholder must meet in order to have a shareholder proposal included in First Choice’s proxy statement pursuant to Rule 14a-8 of the Exchange Act.

W I T N E S E T H:

WHEREAS, the respective boards of directors of each of Enterprise and First Choice have determined that this Agreement and the business combination and related transactions contemplated hereby are fair to, and in the best interests of, their respective entities and shareholders and consistent with and in furtherance of their respective business strategies;

WHEREAS, in accordance with the terms, and subject to the conditions, of this Agreement, (i) First Choice will merge with and into Enterprise, with Enterprise as the surviving entity (the “Merger”), and thereafter (ii) First Choice Bank will merge with and into EB&T, with EB&T as the surviving entity (the “Bank Merger”);

WHEREAS, for United States federal income Tax purposes, the parties intend that the Merger shall qualify as a reorganization under the provisions of Section 368(a) of the Code (a “368 Reorganization”) and intend for this Agreement to constitute a “plan of reorganization” within the meaning of Section 1.368-2(g) of the Regulations;

WHEREAS, as a material inducement and as additional consideration to Enterprise to enter into this Agreement, each of the directors of First Choice, solely in their capacity as shareholders of First Choice, have entered into a voting agreement with Enterprise dated as of the date hereof, the form of which is attached hereto as Exhibit A (collectively, the “Voting Agreements”), pursuant to which each such Person has agreed, among other things, to vote all shares of First Choice Stock owned by such Person in favor of the approval of this Agreement and the transactions contemplated hereby, upon the terms and subject to the conditions set forth in this Agreement and the Voting Agreements;

WHEREAS, the parties desire to make certain representations, warranties and agreements in connection with the transactions described in this Agreement and to prescribe certain conditions thereto; and

WHEREAS, the parties desire that capitalized terms used herein shall have the definitions ascribed to such terms when they are first used herein or as otherwise specified in Article 8 hereof.

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

ARTICLE 1
THE MERGER

Section 1.01 The Merger. Subject to the terms and conditions of this Agreement, at the Effective Time, First Choice shall merge with and into Enterprise in accordance with the DGCL and the CGCL. Upon consummation of the Merger, at the Effective Time, the separate corporate existence of First Choice shall cease and Enterprise shall survive and continue to exist as a corporation incorporated under the laws of the State of Delaware (Enterprise, as the surviving entity in the Merger, sometimes being referred to herein as the “Surviving Entity”).

Section 1.02 Certificate of Incorporation and Bylaws. The certificate of incorporation and bylaws of the Surviving Entity upon consummation of the Merger at the Effective Time shall be the certificate of incorporation and bylaws of Enterprise as in effect immediately prior to the Effective Time.

Section 1.03 Directors and Officers of Surviving Entity.

A-1

TABLE OF CONTENTS

then listed or quoted)), prior to the Effective Time, Enterprise shall take all necessary corporate or other action so that from and after the Effective Time, at the election of Enterprise, either (i) the size of the board of directors of Enterprise (the “Enterprise Board”) is increased by one member, or (ii) one of the then incumbent directors resigns from the Enterprise Board, and in either case one member of the First Choice Board who is independent with respect to Enterprise for purposes of the listing requirements of Nasdaq (or other Trading Market on which the Enterprise Common Stock is then listed or quoted), selected by mutual agreement of First Choice and Enterprise (the “First Choice Director”), is elected or appointed to the Enterprise Board to fill the vacancy on the Enterprise Board created by such increase or resignation, as applicable. Until the Effective Time, First Choice shall cause the First Choice Board to maintain at least one director who is a member of the First Choice Board on the date of this Agreement and who is independent with respect to Enterprise for purposes of the listing requirements of Nasdaq (or other Trading Market on which the Enterprise Common Stock is then listed or quoted).

Section 1.04 Bank Merger.

(a) At such time following the Effective Time as Enterprise may determine, First Choice Bank will be merged with and into EB&T upon the terms and with the effect set forth in the Plan of Bank Merger, the form of which is attached hereto as Exhibit B.

(b) The directors and officers of EB&T immediately prior to the effective time of the Bank Merger shall, from and after such effective time, serve as directors and officers of EB&T, as the surviving bank.

Section 1.05 Effective Time; Closing.

(a) Subject to the terms and conditions of this Agreement, Enterprise and First Choice will make all such filings as may be required by applicable Laws to consummate the Merger. The Merger shall become effective upon filing the Certificate of Merger with the Secretary of State of the State of Delaware on the Closing Date or such later date and/or time as may be specified in the Certificate of Merger (the “Effective Time”). Promptly thereafter, Enterprise shall file a copy of the Certificate of Merger certified by the Secretary of State of the State of Delaware with the Secretary of State of the State of California.

(b) The Bank Merger shall become effective as set forth in the Plan of Bank Merger. Promptly following effectiveness of the Bank Merger, EB&T shall file a copy of the articles of merger certified by the Missouri Division of Finance with the Secretary of State of the State of California and the DFPI. First Choice Bank shall execute such certificates or articles of combination and such other documents and certificates as may be reasonably requested by Enterprise to effectuate the Bank Merger.

(c) The closing of the transactions contemplated by this Agreement (the “Closing”) shall take place on such date and at such time as Enterprise and First Choice mutually agree, which such date shall be no later than fifteen (15) days after all of the conditions to the Closing set forth in Article 6 (other than conditions to be satisfied at the Closing, which shall be satisfied or waived at the Closing) have been satisfied or waived in accordance with the terms hereof (such date, the “Closing Date”) remotely via the electronic exchange of documentation between the parties (via electronic transmission or other similar means for exchanging documentation), or at such place as Enterprise and First Choice may mutually agree.

Section 1.06 Additional Actions. If, at any time after the Effective Time, Enterprise shall consider or be advised that any further deeds, documents, assignments or assurances in Law or any other actions are necessary or desirable to carry out the purposes of this Agreement, First Choice, First Choice Bank and their respective Subsidiaries shall be deemed to have granted to Enterprise an irrevocable power of attorney to execute and deliver, in its official corporate capacity, all such deeds, assignments or assurances in Law and to take any other actions as are necessary or desirable to carry out the purposes of this Agreement, and the officers and directors of Enterprise are authorized in the name of First Choice, First Choice Bank and their respective Subsidiaries to execute and deliver any and all such deeds, assignments or assurances in Law and to take any and all such actions.

TABLE OF CONTENTS

Section 1.07 Reservation of Right to Revise Structure. At Enterprise’s election, without the approval of First Choice, the business combination contemplated by this Agreement may alternatively be structured so that (a) First Choice is merged with and into any other direct or indirect wholly-owned Subsidiary of Enterprise, (b) any direct or indirect wholly-owned Subsidiary of Enterprise is merged with and into First Choice, (c) First Choice Bank is merged with and into any other direct or indirect wholly-owned Subsidiary of EB&T, (d) any direct or indirect wholly-owned Subsidiary of EB&T is merged with and into First Choice Bank, (e) EB&T is merged with and into First Choice Bank, or (f) the Bank Merger is delayed or abandoned and each of First Choice Bank and EB&T continue to operate as separate banking Subsidiaries of Enterprise; provided, however, that no such change shall (i) alter or change the Merger Consideration, (ii) impede or delay consummation of the Merger (including any Closing Regulatory Approval), (iii) adversely alter or change the United States federal income Tax treatment of holders of First Choice Stock in connection with the Merger from what such treatment would have been absent such change (including, but not limited to, any such change that would result in the Merger failing to qualify as a 368 Reorganization), (iv) require submission to or approval of First Choice’s shareholders after the plan of merger set forth in this Agreement has been submitted to or approved by First Choice’s shareholders, (v) require submission to or approval of Enterprise’s shareholders after the plan of merger set forth in this Agreement has been submitted to or approved by Enterprise’s shareholders; or (vi) otherwise adversely affect First Choice, First Choice Bank or any shareholder of First Choice in any material respect. In the event that Enterprise elects to make such a change, the parties agree to execute appropriate documents reasonably required to reflect the change.

ARTICLE 2
MERGER CONSIDERATION; EXCHANGE PROCEDURES

Section 2.01 Stock. Subject to the provisions of this Agreement, at the Effective Time, automatically by virtue of the Merger and without any action on the part of Enterprise, First Choice or any shareholder of First Choice:

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

(b) Each share of First Choice Stock owned directly by Enterprise, First Choice or any of their respective Subsidiaries, as treasury stock or otherwise (other than shares in trust accounts, managed accounts and the like for the benefit of customers), immediately prior to the Effective Time shall be cancelled and retired at the Effective Time without any conversion thereof, and no payment shall be made with respect thereto.

(c) Subject to the other provisions of this Article 2, each share of First Choice Common Stock issued and outstanding immediately prior to the Effective Time (including, for the avoidance of doubt, shares of First Choice Common Stock underlying First Choice Stock Awards) (other than First Choice Common Stock to be cancelled pursuant to Section 2.01(b) and Dissenting Shares) shall be converted into the right to receive 0.6603 (as may be adjusted pursuant to Section 5.18(d), the “Exchange Ratio”) shares of Enterprise Common Stock.

(d) After the Effective Time, (i) all shares of First Choice Common Stock shall no longer be issued and outstanding and shall automatically be cancelled and shall cease to exist, except as to Dissenting Shares, and shall thereafter represent only the right to receive the Stock Consideration, and (ii) each holder of a Certificate or a Book-Entry Share, except as to Dissenting Shares, will cease to have any rights with respect thereto, except the right to receive the Stock Consideration.

At the Effective Time, each First Choice Option granted under any First Choice Benefit Plan that is unvested immediately prior to the Effective Time will vest or be forfeited, as the case may be, pursuant to the terms of the applicable First Choice Benefit Plan and/or award agreement. Each vested and outstanding First Choice Option

A-3

TABLE OF CONTENTS

at the Effective Time shall be canceled and extinguished at the Effective Time and exchanged for the right to receive (without interest) an amount of cash equal to the product of (i) the aggregate number of shares of First Choice Common Stock issuable upon exercise of such First Choice Option and (ii) the excess, if any, of (A) the product of (x) the Exchange Ratio and (y) the Average VWAP as of the Trading Day immediately preceding the Closing Date over (B) the per-share exercise price of such First Choice Option (the “Option Consideration”), less any applicable Taxes required to be withheld with respect to such cash payment. The Surviving Entity shall pay, or cause to be paid, the Option Consideration to holders of First Choice Options through the next administratively practicable payroll following the Effective Time. First Choice shall use Commercially Reasonable Efforts to obtain the written acknowledgement of each holder of a then-outstanding First Choice Option with regard to the cancellation of such First Choice Option and the payment therefor in accordance with the terms of this Agreement.

(b) The provisions of this Section 2.02(b) pertain to all restricted stock awards and other stock-based awards granted by First Choice, including but not limited to awards granted under the First Choice Stock Plans, issued and outstanding immediately prior to the Effective Time except for First Choice Options (collectively, the “First Choice Stock Awards”). At the Effective Time, each First Choice Stock Award that is unsettled or unvested immediately prior to the Effective Time will vest or be cancelled, as the case may be, pursuant to the terms of the applicable First Choice Stock Plan and/or award agreement.

Section 2.03 Merger Consideration. For the avoidance of doubt, the total consideration to be paid by Enterprise in the Merger (the “Merger Consideration”) is (a) the aggregate number of shares of Enterprise Common Stock to be issued to holders of First Choice Common Stock, pursuant to Section 2.01(c) and Section 2.02(b) above, plus cash in lieu of any fractional share interest paid pursuant to Section 2.04 (the “Stock Consideration”), and (b) the aggregate amount of Option Consideration payable to holders of First Choice Options pursuant to Section 2.02(a) above.

Section 2.04 Fractional Shares. Notwithstanding any other provision hereof, no fractional shares of Enterprise Common Stock and no certificates or scrip therefor, or other evidence of ownership thereof, will be issued in the Merger. Each holder of shares of First Choice Common Stock exchanged pursuant to the Merger who would otherwise have been entitled to receive a fraction of a share of Enterprise Common Stock (after taking into account all Certificates and Book-Entry Shares delivered by such holder) shall receive, in lieu thereof, an amount of cash (without interest and rounded to the nearest whole cent) determined by multiplying the fractional share (rounded to the nearest one hundredth of a share) by the Average VWAP as of the Trading Day immediately preceding the Closing Date.

Section 2.05 Plan of Reorganization. It is intended that the Merger shall constitute a 368 Reorganization, and that this Agreement shall constitute a “plan of reorganization” as that term is used in Sections 354 and 361 of the Code and Section 1.368-2(g) of the Regulations. From and after the date of this Agreement and until the Closing, each party hereto shall use Commercially Reasonable Efforts to cause the Merger to qualify as a 368 Reorganization, and each of Enterprise and First Choice shall obtain the opinions referred to in Section 6.01(e).

Section 2.06 Dissenting Shares. Each outstanding share of First Choice Common Stock the holder of which has perfected his, her or its right to dissent pursuant to Chapter 13 of the CGCL, including making a demand of First Choice to purchase his, her or its shares pursuant to Section 1301 of Chapter 13 of the CGCL and submitting his, her or its shares for endorsement pursuant to Section 1302 of Chapter 13 of the CGCL, and has not effectively withdrawn or lost such right as of the Effective Time (the “Dissenting Shares”), shall not be converted into or represent a right to receive the Stock Consideration, and the holder thereof shall be entitled only to such rights as are granted by the CGCL. First Choice shall give Enterprise prompt notice upon receipt by First Choice of any such written demands for payment of the fair value of such shares of First Choice Common Stock and of withdrawals of such demands and any other instruments provided pursuant to the CGCL. If any holder of First Choice Common Stock shall have effectively withdrawn or lost the right to dissent (through failure to perfect or otherwise), the First Choice Common Stock held by such holder shall be converted on a share by share basis into the right to receive the Stock Consideration in accordance with the applicable provisions of this Agreement. Any payments made in respect of Dissenting Shares shall be made by Enterprise within the time period set forth in the CGCL.

Section 2.07 Deposit of Stock Consideration.

(a) At or before the Effective Time, Enterprise shall deposit, or shall cause to be deposited, with the Exchange Agent stock certificates or, at Enterprise’s option, evidence of shares in book entry form, representing the number of shares of Enterprise Common Stock issuable to the holders of First Choice Common Stock pursuant to Section 2.01(c) above and any cash in lieu of fractional shares pursuant to Section 2.04 (collectively, the “Exchange Fund”), and Enterprise shall instruct the Exchange Agent to timely pay such Stock Consideration from the Exchange Fund in accordance with the terms of this Agreement.

(b) Any portion of the Exchange Fund that remains unclaimed as of the first anniversary of the Closing Date (as well as any interest or proceeds from any investment thereof) shall be delivered by the Exchange Agent to Enterprise. Any former shareholders of First Choice who have not theretofore complied with Section 2.08 shall thereafter look only to Enterprise for payment of the Stock Consideration. If any Certificate or Book-Entry Share has not been surrendered prior to the time that is immediately prior to the time at which the Stock Consideration in respect of such Certificate or Book-Entry Share would otherwise escheat to or become the property of any Governmental Authority, any such shares, cash, dividends or distributions in respect of such Certificate or Book-Entry Share shall, to the extent permitted by applicable Law, become the property of the Surviving Entity, free and clear of all claims or interest of any Person previously entitled thereto. Neither the Exchange Agent nor any party to this Agreement shall be liable to any holder of First Choice Common Stock represented by any Certificate or Book-Entry Share for any Stock Consideration which is paid to a public official pursuant to applicable abandoned property, escheat or similar Laws.

Section 2.08 Exchange Procedures.

(a) Enterprise shall cause the Exchange Agent, as soon as practicable after the Effective Time but in no event later than ten (10) days thereafter, to mail to each holder of a Certificate and each holder of a Book-Entry Share(s), (i) a letter of transmittal (“Letter of Transmittal”), which shall specify that delivery shall be effected, and risk of loss and title to the Certificates and Book-Entry Shares shall pass, only upon proper delivery of the Certificates to the Exchange Agent or, in the case of Book-Entry Shares, upon adherence to the procedures set forth in the Letter of Transmittal, and (ii) instructions for use in effecting the surrender of the Certificates or, in the case of Book-Entry Shares, the surrender of such shares, for payment of the Stock Consideration. The Letter of Transmittal shall be subject to the approval of First Choice (which shall not be unreasonably withheld, conditioned or delayed).

(b) Upon surrender to the Exchange Agent of a Certificate or Book-Entry Share(s), together with the Letter of Transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other customary documents as may be reasonably required by the Exchange Agent, the holder of such Certificate or Book-Entry Share(s) shall be entitled to receive in exchange therefor a (i) a certificate (or evidence of shares in book-entry form, as applicable) representing the number of shares of Enterprise Common Stock that such holder is entitled to receive pursuant to the provisions of this Article 2, and (ii) a check in the amount equal to (A) the amount of any cash payable in lieu of fractional shares of Enterprise Common Stock pursuant to Section 2.04 and (B) any dividends and other distributions pursuant to Section 2.08(d). No interest shall be paid or accrued for the benefit of holders of the Certificates or Book-Entry Shares on the Stock Consideration payable in respect of the Certificates or Book-Entry Shares. Until surrendered as contemplated by this Section 2.08(b), each Certificate and each Book-Entry Share shall be deemed at any time after the Effective Time to represent only the right to receive, upon surrender, the Stock Consideration.

(c) In the event a transfer of ownership of a Certificate is not registered in the stock transfer records of First Choice, the Stock Consideration payable with respect to such Certificate shall be issued or paid to a Person other than the Person in whose name the Certificate is registered if (i) such Certificate shall be properly endorsed or otherwise be in proper form for transfer, (ii) the Person requesting such issuance shall pay any transfer or other similar Taxes required by reason of the issuance to a Person other than the registered holder of the Certificate or establish, to the reasonable satisfaction of Enterprise, that such Tax has been paid or is not applicable, and (iii) the Person requesting such issuance or payment shall have complied with the provisions of the Letter of Transmittal. In the event of a

TABLE OF CONTENTS

dispute with respect to ownership of any shares of First Choice Common Stock represented by any Certificate, Enterprise and Exchange Agent shall be entitled to tender to the custody of any court of competent jurisdiction any Stock Consideration payable with respect to such Certificate and file Legal Proceedings interpleading all parties to such dispute, and will thereafter be relieved with respect to any claims thereto.

(d) If a dividend or other distribution is declared by Enterprise in respect of the Enterprise Common Stock, the record date for which is at or after the Effective Time, such declaration shall include dividends or other distributions in respect of all shares of Enterprise Common Stock issuable pursuant to this Agreement. No dividends or other distributions in respect of the Enterprise Common Stock shall be paid to any holder of any unsurrendered Certificate or Book-Entry Shares until such Certificate or Book-Entry Shares are surrendered for exchange in accordance with this Article 2. Subject to applicable Laws, following surrender of any such Certificate or Book-Entry Shares and the issuance of Enterprise Common Stock in exchange therefor, there shall be paid to the holder of such Enterprise Common Stock, (i) at the time of such surrender, the dividends or other distributions with a record date after the Effective Time but prior to such surrender payable with respect to such Enterprise Common Stock and not paid and (ii) at the appropriate payment date, the dividends or other distributions payable with respect to such Enterprise Common Stock with a record date after the Effective Time but with a payment date subsequent to surrender.

(e) The parties intend that no withholding shall be required with respect to the Merger. However, Enterprise (through the Exchange Agent, if applicable) shall be entitled to deduct and withhold from any amounts otherwise payable pursuant to this Agreement to any holder of First Choice Common Stock or First Choice Options such amounts as Enterprise is required to deduct and withhold under applicable Law. Any amounts so deducted and withheld shall be remitted to the appropriate Governmental Authority and upon such remittance shall be treated for all purposes of this Agreement as having been paid to such holder in respect of which such deduction and withholding was made by Enterprise or the Exchange Agent, as applicable.

Section 2.09 Anti-Dilution Provisions. In the event that before the Effective Time Enterprise changes (or establishes a record date for changing) the number of, or provides for the exchange of, shares of Enterprise Common Stock issued and outstanding prior to the Effective Time as a result of a stock split, reverse stock split, stock dividend or distribution, recapitalization, reclassification, exchange or similar transaction with respect to the outstanding Enterprise Common Stock, the Merger Consideration will be appropriately and proportionately adjusted to provide the holders of First Choice Common Stock, First Choice Options and First Choice Stock Awards the same economic effect as contemplated by this Agreement based on the shares of Enterprise Common Stock issued and outstanding prior to such event; provided, that for the avoidance of doubt, no such adjustment shall be made with regard to the Enterprise Common Stock if (a) Enterprise repurchases outstanding shares of Enterprise Common Stock, (b) Enterprise issues additional shares of Enterprise Common Stock and receives consideration for such shares in a bona fide third party transaction, or (c) Enterprise issues employee or director stock options, restricted stock awards, grants or similar equity awards or Enterprise issues Enterprise Common Stock upon exercise or vesting of any such options, grants or awards.

Section 2.10 Lost, Stolen, or Destroyed Certificates. In the event any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if reasonably required by Enterprise or the Exchange Agent, the posting by such Person of a bond in such reasonable amount as Enterprise may determine is reasonably necessary as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the Stock Consideration deliverable in respect thereof pursuant to this Agreement.

(a) Following the execution of this Agreement, First Choice shall take, in accordance with applicable Law and the articles of incorporation and bylaws of First Choice, all action necessary to convene a meeting of its shareholders as promptly as reasonably practicable (and in any event within forty-five (45) days following the time when the Registration Statement becomes effective, subject to extension with the consent of Enterprise (not to be unreasonably withheld or conditioned)) to consider and vote upon the approval of this Agreement and the transactions contemplated hereby (including the Merger) and any other matters required to be approved by First Choice’s shareholders in order to permit consummation of the Merger and the transactions contemplated hereby (including any adjournment or postponement thereof, the “First Choice Meeting”), and shall, subject to Section 5.11 and the last sentence of this Section 5.04(a), use its Commercially Reasonable Efforts to solicit such approval by such shareholders. Subject to Section 5.11 and the last sentence of this Section 5.04(a), First Choice shall use its Commercially Reasonable Efforts to obtain the Requisite First Choice Shareholder Approval to consummate the Merger and the other transactions contemplated hereby. Except with the prior approval of Enterprise, which shall not be unreasonably withheld, no other matters shall be submitted for approval of First Choice shareholders at the First Choice Meeting.

In the event that there are sufficient shares of First Choice Common Stock represented (in person or by proxy) at the First Choice Meeting to secure the Requisite First Choice Shareholder Approval, First Choice will not adjourn or postpone the First Choice Meeting unless the First Choice Board reasonably determines in good faith, after consultation with the advice of counsel, that (i) such adjournment or postponement is required by applicable Law in order to ensure that any required supplement or amendment to the Proxy Statement-Prospectus is provided to the holders of First Choice Common Stock with a reasonable amount of time in advance of the First Choice Meeting or (ii) failure to do so would otherwise breach or reasonably be expected to result in a breach of its fiduciary duties under applicable Law. First Choice shall keep Enterprise updated with respect to the proxy solicitation results in connection with the First Choice Meeting as reasonably requested by Enterprise.

(c) Except to the extent provided otherwise in Section 5.11, First Choice shall adjourn or postpone the First Choice Meeting, if, as of the time for which the First Choice Meeting is originally scheduled there are insufficient shares of First Choice Common Stock represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of such meeting or, if on the

Section 5.05 Enterprise Shareholder Approval. (a) Enterprise shall take, in accordance with applicable Law and the certificate of incorporation and bylaws of Enterprise, all action necessary to convene a special meeting of its shareholders as promptly as reasonably practicable (and in any event within forty-five (45) days following the time when the Registration Statement becomes effective, subject to extension with the consent of First Choice (not to be unreasonably withheld or conditioned)) to consider and obtain the Requisite Enterprise Shareholder Approval (including any adjournment or postponement thereof, the “Enterprise Meeting”) and shall use its Commercially Reasonable Efforts to solicit such approval by such shareholders. The Enterprise Board shall at all times prior to and during the Enterprise Meeting recommend such approval (the “Enterprise Recommendation”) and (b) the Proxy Statement-Prospectus shall include the Enterprise Recommendation. Neither the Enterprise Board nor any committee thereof shall withhold, withdraw, change, qualify, amend or modify, or publicly propose to withdraw, change, qualify, amend or modify, in a manner adverse in any respect to the interest of First Choice, or take any other action or make any other public statement inconsistent with, the Enterprise Recommendation.

Section 5.06 Takeover Laws. Enterprise shall use Commercially Reasonable Efforts to exempt (or cause the continued exemption of) this Agreement, the Merger and the Bank Merger from the requirements of any applicable antitakeover statute or regulation and from any similar provisions under the certificate of incorporation and bylaws of Enterprise and the organizational documents of EB&T.

Section 5.07 Registration Statement; Proxy Statement-Prospectus; Nasdaq Listing.

(a) Enterprise and First Choice agree to cooperate in the preparation of the Registration Statement to be filed by Enterprise with the SEC in connection with the issuance of Enterprise Common Stock in the Merger (including the Proxy Statement-Prospectus and all related documents). First Choice shall use Commercially Reasonable Efforts to deliver to Enterprise such financial statements and related analysis of First Choice as may be required by Law in order to file the Registration Statement and any other report required to be filed by Enterprise with the SEC, in each case, in compliance with applicable Laws and shall provide Enterprise with any other information concerning itself that Enterprise may reasonably request in connection with the drafting and preparation of the Registration Statement and the Proxy Statement-Prospectus. Enterprise agrees to use Commercially Reasonable Efforts to cause the Registration Statement to be filed with the SEC within sixty (60) days from the date hereof, and to be declared effective by the SEC as promptly as reasonably practicable after the filing thereof. First Choice agrees to cooperate with Enterprise and Enterprise’s counsel and accountants in requesting and obtaining appropriate opinions, consents and letters from First Choice’s independent auditors in connection with the Registration Statement and the Proxy Statement-Prospectus. After the Registration Statement is declared effective under the Securities Act, First Choice, at its own expense, shall promptly mail or cause to be mailed the Proxy Statement-Prospectus to its shareholders.

(b) Enterprise shall use Commercially Reasonable Efforts to ensure that the Proxy Statement-Prospectus and the Registration Statement shall comply as to form in all material respects with the applicable provisions of the Securities Act and the Exchange Act and the rules and regulations thereunder. Each of Enterprise and First Choice agrees, as to itself and its Subsidiaries, that none of the information supplied or to be supplied by it for inclusion or incorporation by reference in (i) the Registration Statement will, at the time it is filed with the SEC, at any time it is amended or supplemented, or at the time it becomes effective under the Securities Act, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading and (ii) the Proxy Statement-Prospectus will, at the date of mailing to shareholders, at the time of the First Choice Meeting and Enterprise Meeting, or at any time it is amended or supplemented, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which such statement was made, not misleading. Each of Enterprise and First Choice further agrees that if it becomes aware that any information furnished by it would cause any of

A-45

TABLE OF CONTENTS

the statements in the Registration Statement or the Proxy Statement-Prospectus to be false or misleading with respect to any material fact, or to omit to state any material fact necessary to make the statements therein not false or misleading, to promptly inform the other party thereof and to take appropriate steps to correct the Registration Statement or the Proxy Statement-Prospectus. Enterprise will advise First Choice, promptly after Enterprise receives notice thereof, (A) of the time when the Registration Statement has become effective or any supplement or amendment has been filed, (B) of the issuance of any stop order or the suspension of the qualification of Enterprise Common Stock for offering or sale in any jurisdiction or of the initiation or threat of any proceeding for any such purpose, and (C) of any request by the SEC for the amendment or supplement of the Registration Statement or upon the receipt of any comments (whether written or oral) from the SEC or its staff. Enterprise will provide First Choice and its counsel with a reasonable opportunity to review and comment on (and will consider such comments in good faith) (x) the Registration Statement (including the Proxy Statement-Prospectus) prior to its being filed with the SEC, (y) all amendments and supplements to the Registration Statement (including the Proxy Statement-Prospectus) and, (z) except to the extent such response is submitted under confidential cover, all responses to requests for additional information and replies to comments of the SEC, prior to their being filed with, or sent to the SEC, and reasonable good faith consideration shall be given to any comments made by First Choice and its counsel. Enterprise will provide First Choice and its counsel with a copy of all such filings made with the SEC. If at any time prior to the First Choice Meeting and Enterprise Meeting there shall occur any event that should be disclosed in an amendment or supplement to the Proxy Statement-Prospectus or the Registration Statement, Enterprise shall use Commercially Reasonable Efforts to promptly prepare and file such amendment or supplement with the SEC (if required under applicable Law) and cooperate with First Choice to mail such amendment or supplement to First Choice shareholders (if required under applicable Law).

(c) Enterprise agrees to use Commercially Reasonable Efforts to cause the shares of Enterprise Common Stock to be issued in connection with the Merger to be approved for listing on Nasdaq (or other Trading Market on which the Enterprise Common Stock is then listed or quoted), subject to official notice of issuance, prior to the Effective Time.

Section 5.08 Regulatory Filings; Consents.

(a) Each of Enterprise and First Choice and their respective Subsidiaries shall cooperate and use their Commercially Reasonable Efforts (i) to prepare all documentation (including the Registration Statement and Proxy Statement-Prospectus), and Enterprise shall make, all filings with, to send all notices to, and to obtain all Permits, consents, approvals and authorizations of, all third parties and Governmental Authorities necessary to consummate the transactions contemplated by this Agreement, including without limitation, the Closing Regulatory Approvals and the consents, approvals and notices under the Contracts set forth on Section 3.05(c), (ii) to comply with the terms and conditions of such permits, consents, approvals and authorizations and (iii) to cause the transactions contemplated by this Agreement to be consummated as expeditiously as practicable; provided, however, that in no event shall Enterprise be required to agree to any prohibition, limitation, or other requirement which would (A) materially prohibit or materially limit the ownership or operation by Enterprise or any Enterprise Subsidiary (including First Choice and any First Choice Subsidiary after Closing) of all or any material portion of its business or assets, (B) compel Enterprise or any Enterprise Subsidiary (including First Choice and any First Choice Subsidiary after Closing) to dispose of all or any material portion of its business or assets, (C) cause any portion of any First Choice Regulatory Agreement to be enforceable against Enterprise or EB&T after the Merger, or (D) be reasonably expected to have a Material Adverse Effect on the Surviving Entity, taken as a whole (together, the “Burdensome Conditions”). Without limiting the generality of the foregoing, as soon as practicable and in no event later than thirty (30) days after the date of this Agreement, Enterprise and First Choice shall, and shall cause their respective Subsidiaries to, each prepare, and Enterprise shall file, any applications, notices and filings required in order to obtain the Closing Regulatory Approvals and any other Permits, consents, approvals and authorizations of any Governmental Authority necessary to consummate the transactions contemplated hereby (including the Merger and the Bank Merger). Subject to applicable Law, (w) Enterprise and First Choice will furnish each other and each other’s counsel with all information concerning themselves, their Subsidiaries, directors, trustees, officers and shareholders and such other matters as may be reasonably necessary or advisable in connection with obtaining any Regulatory

(b) First Choice will use Commercially Reasonable Efforts, and Enterprise shall reasonably cooperate with First Choice at First Choice’s request, to obtain all consents, approvals, authorizations, waivers or similar affirmations with respect to any Contracts set forth on Section 3.05(c) of the First Choice Disclosure Schedule and all Leases set forth on Section 3.30(e) of the First Choice Disclosure Schedule; provided, that, except as otherwise contemplated by this Agreement, neither First Choice nor any First Choice Subsidiary will be required to make any payment to or grant any concessions to any third party in connection therewith. Each party will, to the extent permitted by applicable Law, notify the other party promptly and promptly furnish the other party with copies of notices or other communications received by such party or any of its Subsidiaries from any Person alleging that the consent of such Person (or another Person) is or may be required in connection with the transactions contemplated by this Agreement (and the response thereto from such party, its Subsidiaries or its representatives). First Choice and Enterprise will reasonably consult with each other and their respective representatives so as to permit First Choice and Enterprise and their respective representatives to be knowledgeable regarding the status of such effort, cooperate to take appropriate measures to obtain such consents and avoid or mitigate any adverse consequences that may result from the foregoing.

Section 5.09 Publicity. Enterprise and First Choice shall consult with each other before issuing any press release with respect to this Agreement or the transactions contemplated hereby and shall not issue any such press release or make any such public statement without the prior consent of the other party, which shall not be unreasonably delayed or withheld; provided, however, that Enterprise and First Choice may, without the prior consent of the other party (but after such consultation, to the extent practicable in the circumstances), issue such press release or make such public statements as may upon the advice of counsel be required by Law or the rules and regulations of the SEC or Nasdaq (or other Trading Market on which the Enterprise Common Stock is then listed or quoted). It is understood that Enterprise shall assume primary responsibility for the preparation of joint press releases relating to this Agreement, the Merger and the other transactions contemplated hereby.

Section 5.10 Access; Current Information.

(a) During the period from the date of this Agreement until the Effective Time (or earlier termination of this Agreement in accordance with Article 7), First Choice and Enterprise shall, for the purposes of verifying the representations and warranties of Enterprise and EB&T and First Choice and First Choice Bank, respectively, and preparing for the Merger and the other matters contemplated by this Agreement, (i) upon reasonable notice and subject to applicable Laws, afford the other party and its officers, employees, counsel, accountants and other authorized representatives access (subject to any reasonable restrictions imposed by First Choice or Enterprise with respect to in-person access in light of COVID-19 concerns), during normal business hours, to its and its Subsidiaries’ books, records (including, without limitation, Tax Returns and, subject to the consent of the independent auditors, work papers of independent auditors), information technology systems, properties and personnel and to such other information as the other party may reasonably request, and (ii) furnish to the other party, upon reasonable request, all such other information concerning its business, properties, personnel and Subsidiaries that is substantially similar in scope to the information provided to the other party in connection with its diligence review prior to the date of this Agreement.

A-47

TABLE OF CONTENTS

(b) During the period from the date of this Agreement until the Effective Time (or earlier termination of this Agreement in accordance with Article 7), First Choice will cause one or more of its designated representatives to confer with representatives of Enterprise and report the general status of its ongoing operations, at such times and in such manner as Enterprise may reasonably request.

(c) During the period from the date of this Agreement until the Effective Time (or earlier termination of this Agreement in accordance with Article 7), each of Enterprise and First Choice will promptly notify the other party in writing of any matter hereafter arising which, if existing, occurring or known at the date of this Agreement, would have been required to be set forth or described in the Enterprise Disclosure Schedule or the First Choice Disclosure Schedule, as applicable, or which is necessary to correct any information in such party’s Disclosure Schedule that has been rendered materially inaccurate thereby. Each such notice shall include, or be accompanied by, a proposed supplement or amendment to such party’s Disclosure Schedule regarding such matter (a “Schedule Supplement”). Each Schedule Supplement shall be deemed to be incorporated into and to supplement and amend the First Choice Disclosure Schedule or Enterprise Disclosure Schedule, as applicable, as of the date of this Agreement and as of the Closing Date; provided, however, that if the matter which is the subject of the Schedule Supplement constitutes or relates to something that could provide Enterprise with a right to terminate this Agreement in accordance with Section 7.01(e) and Enterprise does not elect to terminate this Agreement prior to the earlier of (i) five (5) Business Days after the expiration of the applicable cure period and (ii) the Expiration Date, then Enterprise shall be deemed to have irrevocably waived any right to terminate this Agreement on account of such matter.

(d) No investigation by a party or its representatives shall be deemed to modify or waive any representation, warranty, covenant or agreement of the other party or its Subsidiary bank set forth in this Agreement, or the conditions to the respective obligations of Enterprise and First Choice to consummate the transactions contemplated hereby.

(e) Notwithstanding anything in this Section 5.10 to the contrary, no party shall be required to provide the other party with access or disclose information where such access or disclosure would, in the reasonable opinion of such party’s counsel, jeopardize the attorney-client privilege of the such party, or contravene any binding Contract entered into by such party prior to the date of this Agreement or any Law, Order or fiduciary duty applicable to such party. In the event any of the restrictions in this Section 5.10(e) shall apply, each party shall use Commercially Reasonable Efforts to make appropriate alternate disclosure arrangements, including adopting additional specific procedures to protect the confidentiality of sensitive material and to ensure compliance with applicable Laws.

Section 5.11 No Solicitation by First Choice; Superior Proposals.

(a) Subject to Section 5.11(b), First Choice and First Choice Bank shall not, and shall instruct their respective Subsidiaries, officers, directors, employees, investment bankers, financial advisors, attorneys, accountants, consultants, Affiliates and other agents (collectively, the “First Choice Representatives”) not to, directly or indirectly, (i) initiate, solicit, induce or knowingly encourage, or knowingly take any action to facilitate the making of, any inquiry, offer or proposal which constitutes, or could reasonably be expected to lead to, an Acquisition Proposal; (ii) participate in discussions or negotiations regarding any Acquisition Proposal or furnish, or otherwise afford access, to any Person (other than Enterprise or any Enterprise Subsidiary) any information or data with respect to First Choice or any First Choice Subsidiary or otherwise in furtherance of an Acquisition Proposal; (iii) release any Person from, waive any provision of, or fail to enforce any confidentiality agreement or standstill agreement to which First Choice is a party in furtherance of an Acquisition Proposal; or (iv) enter into any agreement, agreement in principle or letter of intent with respect to any Acquisition Proposal or approve or resolve to approve any Acquisition Proposal or any agreement, agreement in principle or letter of intent relating to an Acquisition Proposal (other than a confidentiality agreement permitted by this Section 5.11(b)(iii)), provided, however, that nothing in this Section 5.11(a) shall prohibit First Choice, the First Choice Board or any First Choice Representative from making any inquiries with respect to a bona fide unsolicited written Acquisition Proposal solely for the purpose of clarifying such Acquisition Proposal to enable the First Choice Board to make the determination described in Section 5.11(b). Any violation of the foregoing restrictions by First Choice or any First Choice Representative, whether or not such First Choice Representative is so authorized and whether or not

A-48

TABLE OF CONTENTS

such First Choice Representative is purporting to act on behalf of First Choice or otherwise, shall be deemed to be a breach of this Agreement by First Choice. First Choice and First Choice Subsidiaries shall, and shall cause each of the First Choice Representatives to, immediately cease and cause to be terminated any and all existing discussions, negotiations, and communications with any Persons with respect to any existing or potential Acquisition Proposal.

(b) Notwithstanding Section 5.11(a) or any other provision of this Agreement, at any time prior to obtaining the Requisite First Choice Shareholder Approval, First Choice may take any of the actions described in Section 5.11(a) if, but only if, (i) First Choice has received a bona fide unsolicited written Acquisition Proposal that did not result from a breach of this Section 5.11; (ii) the First Choice Board reasonably determines in good faith, after consultation with its outside financial advisor and outside legal counsel, that (a) such Acquisition Proposal constitutes or could reasonably be expected to lead to a Superior Proposal and (b) the failure to take such actions would breach or reasonably be expected to result in a breach of its fiduciary duties under applicable Law; and (iii) prior to furnishing or affording access to any information or data with respect to First Choice or any First Choice Subsidiary or otherwise relating to an Acquisition Proposal, First Choice receives from such Person a confidentiality agreement with terms no less favorable to First Choice than those contained in the confidentiality agreement with Enterprise (it being understood that nothing therein shall have the effect of a standstill provision). First Choice shall promptly provide to Enterprise any non-public information regarding First Choice or First Choice Subsidiaries provided to any other Person which was not previously provided to Enterprise, such additional information to be provided no later than the date of provision of such information to such other party.

(c) First Choice shall promptly (and in any event within 24 hours) notify Enterprise in writing if any proposals or offers are received by, any information is requested from, or any negotiations or discussions are sought to be initiated or continued with, First Choice or the First Choice Representatives, in each case in connection with any Acquisition Proposal, and such notice shall indicate the name of the Person initiating such discussions or negotiations or making such proposal, offer or information request and the material terms and conditions of any proposals or offers (and, in the case of written materials relating to such proposal, offer, information request, negotiations or discussion, providing copies of such materials (including e-mails or other electronic communications), except to the extent that such materials constitute confidential information of the party making such offer or proposal under an effective confidentiality agreement or any such disclosure would jeopardize attorney-client privilege). First Choice agrees that it shall keep Enterprise informed, on a reasonably current basis, of the status and terms of any such proposal, offer, information request, negotiations or discussions (including any amendments or modifications of any material terms to such proposal, offer or request).

(d) Subject to Section 5.11(e), neither the First Choice Board nor any committee thereof shall (i) withhold, withdraw, change, qualify, amend or modify, or publicly propose to withdraw, change, qualify, amend or modify, in a manner adverse in any respect to the interest of Enterprise, or take any other action or make any other public statement inconsistent with, the First Choice Recommendation; (ii) fail to publicly affirm the First Choice Recommendation within five (5) Business Days following a request by Enterprise (or such fewer number of days as remains prior to the First Choice Meeting); (iii) approve or recommend, or publicly propose to approve or recommend, any Acquisition Proposal; (iv) resolve to take, or publicly announce an intention to take, any of the foregoing actions (each of (i), (ii), (iii) or (iv) a “First Choice Subsequent Determination”); or (v) enter into (or cause First Choice or any of its Subsidiaries to enter into) any letter of intent, agreement in principle, acquisition agreement or other agreement (a) related to any Acquisition Transaction (other than a confidentiality agreement entered into in accordance with the provisions of Section 5.11(b)) or (b) requiring First Choice to abandon, terminate or fail to consummate the Merger or any other transaction contemplated by this Agreement.

(e) Notwithstanding Section 5.11(d) or any other provision of this Agreement, prior to obtaining the Requisite First Choice Shareholder Approval, the First Choice Board (or any committee thereof) may make a First Choice Subsequent Determination after the fifth (5th) Business Day following Enterprise’s receipt of a notice (the “Notice of Determination”) from First Choice informing Enterprise that the First Choice Board (or such committee) has determined in good faith, after consultation

A-49

TABLE OF CONTENTS

with outside legal counsel and its financial advisor, that an Acquisition Proposal constitutes a Superior Proposal and the failure to make a First Choice Subsequent Determination with respect to such Superior Proposal would breach or reasonably be expected to result in a breach of its fiduciary duties under applicable Law (it being understood that the initial determination under this clause will not be considered a First Choice Subsequent Determination), but only if: (i) the Notice of Determination includes or is accompanied by the material terms and conditions of such Superior Proposal and the identity of the Person making such Superior Proposal, including copies of any proposed material agreements providing for such Superior Proposal; (ii) during the five (5) Business Day period after receipt of the Notice of Determination (the “Notice Period”), First Choice and the First Choice Board shall have negotiated in good faith with Enterprise, to the extent Enterprise desires to negotiate, to make such adjustments, modifications or amendments to the terms and conditions of this Agreement as would enable First Choice to proceed with the First Choice Recommendation without a First Choice Subsequent Determination; provided, however, that Enterprise shall not have any obligation to propose any adjustments, modifications or amendments to the terms and conditions of this Agreement, and (iii) at the end of the Notice Period, after taking into account any such adjusted, modified or amended terms, if any, as may have been proposed by Enterprise in writing before expiration of the Notice Period, the First Choice Board has again in good faith, after consultation with outside legal counsel and its financial advisor, made the determination that such Acquisition Proposal constitutes a Superior Proposal and the failure to make a First Choice Subsequent Determination with respect to such Superior Proposal would breach or reasonably be expected to result in a breach of its fiduciary duties under applicable Law. In the event of any material revisions to an Acquisition Proposal that is the subject of a Notice of Determination and that occur prior to a First Choice Subsequent Determination, First Choice shall be required to deliver a new Notice of Determination to Enterprise and again comply with the requirements of this Section 5.11(e), except that the Notice Period shall be reduced to three (3) Business Days.

Section 5.12 Indemnification.

(a) For a period of six years from and after the Effective Time, to the fullest extent permitted by applicable Law and the articles of incorporation and bylaws of First Choice in effect on the date of this Agreement, and in any event subject to the provisions of Section 5.12(b), Enterprise shall (i) indemnify and hold harmless the present and former directors and officers of First Choice and First Choice Bank (the “Indemnified Parties”) against all costs or expenses (including reasonable attorney’s fees), judgments, fines, losses, claims, damages, or liabilities incurred in connection with any actual or threatened Legal Proceeding arising out of actions or omissions of such Persons in the course of performing their duties for First Choice or any First Choice Subsidiary occurring at or before the Effective Time (including in connection with the transactions contemplated by this Agreement) (each a “Claim”), and shall promptly advance expenses to each Indemnified Party from time-to-time as incurred in connection with a Claim, to the same extent as the Indemnified Parties have the right to expense advancement pursuant to applicable Law, the articles of incorporation and bylaws of First Choice in effect on the date of this Agreement, and/or any written agreement by and between First Choice or First Choice Bank and an Indemnified Party providing for the indemnification of such Indemnified Party currently in effect as of the date of this Agreement; provided, that each Indemnified Party to whom expenses are advanced provides a reasonable and customary undertaking to repay such advances, if it is ultimately determined that such Person is not entitled to indemnification.

(b) Any Indemnified Party wishing to claim indemnification under this Section 5.12 shall promptly notify Enterprise upon learning of any Claim, provided, that failure to so notify shall not affect the obligation of Enterprise under this Section 5.12, unless, and only to the extent that, Enterprise is materially prejudiced in the defense of such Claim as a consequence. In the event of any such Claim (whether asserted or claimed prior to, at or after the Effective Time), (i) (A) Enterprise shall have the right to assume the defense thereof and Enterprise shall not be liable to such Indemnified Party for any legal expenses for other counsel or any other expenses subsequently incurred by such Indemnified Party in connection with the defense thereof, unless such Indemnified Party is advised in writing by counsel that the defense of such Indemnified Party by Enterprise would create an actual or potential conflict of interest (in which case, Enterprise shall not be obligated to reimburse or indemnify any Indemnified Party for the expenses of more than one separate counsel in addition to one local counsel in the

A-50

TABLE OF CONTENTS

jurisdiction where defense of any Claim has been or is to be asserted (if the Claim involves more than one Indemnified Party, Enterprise shall only be obligated to pay for one separate counsel and one local counsel for all Indemnified Parties)), and (B) such Indemnified Party will cooperate in the defense of any such matter, (ii) Enterprise shall not be liable for any settlement effected without its prior written consent (which consent shall not be unreasonably withheld or delayed) and Enterprise shall not settle any Claim without such Indemnified Party’s prior written consent (which consent shall not be unreasonably withheld or delayed), and (iii) Enterprise shall have no obligation hereunder to any Indemnified Party if such indemnification would be in violation of any applicable United States federal or state banking Laws or regulations, or in the event that a United States federal or state banking agency or a court of competent jurisdiction shall determine by final and unappealable adjudication that indemnification of an Indemnified Party in the manner contemplated hereby is prohibited by applicable Laws, whether or not related to banking Laws.

(c) Subject to the terms described in this Section 5.12(c), Enterprise shall (i) maintain in effect for a period of six (6) years following the Effective Time, First Choice’s current directors’ and officers’ liability insurance policies covering the Indemnified Parties, (ii) obtain, as of the Effective Time, “tail” insurance policies with a claims period of six (6) years following the Effective Time with at least the same coverage and amounts and containing terms and conditions that are no less advantageous to the Indemnified Parties as the policies currently provided by First Choice, or (iii) purchase and provide for a period of six (6) years following the Effective Time, directors’ and officers’ liability insurance policies from a carrier assigned a claims paying ability rating by A.M. Best First Choice, Inc. of “A (Excellent)” or higher with at least the same coverage and amounts and containing terms and conditions that are no less advantageous to the Indemnified Parties as the policies currently provided by First Choice, in each case with respect to claims arising out of or relating to events which occurred before or at the Effective Time; provided, however, that in no event shall Enterprise be required to expend per year pursuant to this Section 5.12(c) more than two hundred fifty percent (250%) of the annual cost currently expended by First Choice with respect to such insurance (the “Maximum D&O Premium”); provided, further, that if the amount of the annual premium necessary to maintain or procure such insurance coverage exceeds the Maximum D&O Premium, Enterprise shall maintain or procure the most advantageous policies of directors’ and officers’ insurance (or “tail” coverage obtainable for a premium equal to the Maximum D&O Premium). In connection with the foregoing, First Choice agrees that in order for Enterprise to fulfill its obligations pursuant to this Section 5.12(c), Indemnified Parties may be required to provide such insurer or substitute insurer with such reasonable and customary representations as such insurer may request.

(d) If, following the Effective Time, Enterprise or any of its successors and assigns (i) shall consolidate with or merge into any Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger, or (ii) shall transfer all or substantially all of its property and assets to any Person, then, in each such case, proper provision shall be made so that the successors and assigns of Enterprise shall assume the obligations set forth in this Section 5.12.

(e) These rights shall survive consummation of the Merger and are intended to benefit, and shall be enforceable by, each Indemnified Party. After the Effective Time, the obligations of Enterprise under this Section 5.12 shall not be terminated or modified in such a manner as to adversely affect any Indemnified Party unless the affected Indemnified Party shall have consented in writing to such termination or modification. If any Indemnified Party makes any claim for indemnification or advancement of expenses under this Section 5.12 that is denied by Enterprise, and a court of competent jurisdiction determines that the Indemnified Party is entitled to such indemnification or advancement of expense, in whole or in part, then Enterprise or the Surviving Entity shall pay such Indemnified Party’s costs and expenses, including legal fees and expenses, incurred in connection with enforcing such claim against Enterprise.

(f) Nothing in this Agreement is intended to, shall be construed to or shall release, waive or impair any rights to directors’ and officers’ insurance claims under any policy that is or has been in existence with respect to First Choice or any First Choice Subsidiary for any of their respective directors, officers or other employees, it being understood and agreed that the indemnification provided for in this Section 5.12 is not prior to or in substitution for any such claims under such policies.

(a) With respect to any Enterprise Benefit Plan in which any employee of First Choice or any First Choice Subsidiary on the Closing Date (the “Continuing Employees”) will participate, Enterprise shall, or shall cause First Choice to, recognize, for vesting, eligibility and benefit accrual purposes (other than benefit accruals under a defined pension plan), all service of the Continuing Employees with First Choice or any First Choice Subsidiary (including any predecessors thereof) as if such service were with Enterprise; provided, however, such service shall not be recognized to the extent that (i) such recognition would result in a duplication of benefits or (ii) such service was not recognized under the corresponding First Choice Benefit Plan.

(b) Enterprise shall maintain the terms and conditions of employment applicable to the Continuing Employees (including salary, incentive compensation opportunities, severance benefits, medical benefits, other welfare benefits, fringe benefits, work location, and position) on terms and conditions that are no less favorable, in the aggregate, to the terms and conditions of employment of such Continuing Employees provided by First Choice or any First Choice Subsidiary immediately prior to the Closing until the harmonization date identified on Section 5.13(b) of the Enterprise Disclosure Schedule applicable to such term or condition. Notwithstanding the foregoing, nothing in this provision shall prevent Enterprise from transferring some or all of the Continuing Employees to Enterprise’s benefit plans on substantially similar terms as existing Enterprise employees and nothing in this section shall guarantee any Continuing Employee the right to continued employment for any period of time.

(c) Enterprise shall (i) waive or cause to be waived any waiting periods, evidence of insurability requirements, or pre-existing condition limitations and similar limitations with respect to participation and coverage requirements applicable to the Continuing Employees and (ii) provide each Continuing Employee with credit for any co-payments and deductibles paid prior to the Closing Date in satisfying any applicable deductible or out-of-pocket requirements under such group health plan.

(d) With respect to severance benefits, in addition to the term of employment of such Continuing Employee at Enterprise and/or EB&T, Enterprise shall also credit the term of employment of any Continuing Employee who becomes entitled to severance benefits after Closing with service credit relating to their service provided to First Choice and/or First Choice Bank prior to the Effective Time to the extent such service would have been recognized under the First Choice’s severance plan as in effect immediately prior to Closing.

(e) This Section 5.13 shall be binding upon and inure solely to the benefit of each of the parties to this Agreement, and nothing in this Section 5.13, express or implied, shall confer upon any other Person any rights or remedies of any nature whatsoever under or by reason of this Section 5.13. Nothing contained herein, express or implied, shall be construed to establish, amend or modify any benefit plan, program, agreement or arrangement. The parties hereto acknowledge and agree that the terms set forth in this Section 5.13 shall not create any right in any employee or any other Person to any continued employment with First Choice or its Subsidiaries, Enterprise or any of their respective Affiliates or compensation or benefits of any nature or kind whatsoever.

Section 5.14 Exemption from Liability Under Section 16(b). Prior to the Effective Time, each of Enterprise and First Choice shall take all steps as may be necessary or appropriate to exempt the conversion of shares of First Choice Common Stock into shares of Enterprise Common Stock pursuant to the terms of this Agreement by employees and directors of First Choice who may become an officer or director of Enterprise subject to the reporting requirements of Section 16(a) of the Exchange Act.

Section 5.15 Notification of Certain Changes. Enterprise and First Choice shall promptly advise the other party of any change or event (a) having, or which could reasonably be expected to have a Material Adverse Effect or (b) which it believes would, or which could reasonably be expected to, cause or constitute a material breach of any of its or its Subsidiary bank’s representations, warranties or covenants contained herein, which breach could reasonably be expected to give rise, individually or in the aggregate, to the failure of a condition in Article 6 to be satisfied on the Closing Date, provided, that any failure to give notice in accordance with the foregoing with respect to any change or event shall not be deemed to constitute a violation of this Section 5.15, or otherwise constitute a breach of this Agreement by the party failing to give such notice, in each case, unless the underlying change or event would independently result in a failure of any of the conditions set forth in Section 6.02 to be satisfied on the Closing Date.

Section 5.16 Transition; Informational Systems Conversion. From and after the date hereof, each of Enterprise and First Choice shall use its Commercially Reasonable Efforts to facilitate the integration of First Choice and First Choice Subsidiaries with the business of Enterprise and Enterprise Subsidiaries following consummation of the transactions contemplated hereby, and shall meet on a regular basis to discuss and plan for the conversion of the data processing and related electronic informational systems of First Choice and First Choice Subsidiaries (the “Informational Systems Conversion”) in such a manner reasonably sufficient to provide reasonable assurances that a successful Informational Systems Conversion will occur. The Informational Systems Conversion will occur, after the Closing Date and at such date as may be specified by Enterprise, subject to any applicable Laws, including Laws regarding the exchange of information and other Laws regarding competition. Without limiting the generality of the foregoing, First Choice shall, subject to any such applicable Laws: (i) reasonably cooperate with Enterprise to establish a project plan as specified by Enterprise to effectuate the Informational Systems Conversion; (ii) use Commercially Reasonable Efforts to have First Choice’s outside contractors continue to support both the Informational Systems Conversion effort and its ongoing needs until the Informational Systems Conversion can be established; (iii) provide, or use Commercially Reasonable Efforts to obtain from any outside contractors, all data or other files and layouts reasonably requested by Enterprise for use in planning the Informational Systems Conversion, as soon as reasonably practicable; (iv) provide reasonable access to First Choice’s personnel and facilities and its outside contractors’ personnel and facilities, to the extent necessary to enable the Informational Systems Conversion effort to be completed on schedule; and (v) give notice of termination, conditioned upon the completion of the transactions contemplated by this Agreement, of the Contracts of outside data, item and other processing contractors or other third-party vendors to which First Choice or any First Choice Subsidiary is bound, if requested to do so by Enterprise, to the extent permitted by such Contracts; provided, that First Choice shall not be required to take any action under this Section 5.16 that, after consultation with Enterprise regarding First Choice’s concerns in the matter, is reasonably likely to prejudice or adversely affect in any material respect its rights under any such Contracts in the event the Closing does not occur. First Choice shall pay any reasonable out of pocket expenses due third parties incurred in connection with the actions described in this Section 5.16. Such access as contemplated by this Section 5.16 shall be conducted by Enterprise in a manner which does not adversely affect the normal operations of First Choice or First Choice Bank and neither First Choice nor First Choice Bank shall be required to provide access to or disclose information (i) which would jeopardize the attorney-client privilege of First Choice or First Choice Bank or contravene any binding Contract entered into prior to the date of this Agreement or any Law, Order or fiduciary duty, (ii) except as otherwise provided in this Agreement, relating to an Acquisition Proposal, a Superior Proposal, a First Choice Subsequent Determination or any matters related thereto, or (iii) except as otherwise provided in this Agreement, related to First Choice’s or First Choice Bank’s directors’, officers’, employees’, accountants’, counsels’, advisors’ (including investment bankers), agents’, or other representatives’, consideration of, or deliberations regarding, the transactions contemplated by this Agreement.

Section 5.17 No Control of Other Party’s Business. Nothing contained in this Agreement shall give Enterprise, directly or indirectly, the right to control or direct the operations of First Choice or First Choice Subsidiaries prior to the Effective Time, and nothing contained in this Agreement shall give First Choice, directly or indirectly, the right to control or direct the operations of Enterprise or Enterprise Subsidiaries prior to the Effective Time.

Section 5.18 Environmental Matters.

(a) Phase I Assessments. For any First Choice Leased Property which is identified by Enterprise within twenty (20) days of this Agreement, Enterprise may, at its sole cost and expense, obtain, within sixty (60) days after the date of such notice, written reports of a Phase I ESA for, and of the presence or absence of asbestos-containing material (“ACM”) at, each such property, prepared by an environmental consultant or consultants experienced in performing Phase I ESAs of, and in investigating for ACM at, such real property (“Environmental Consultant”) and reasonably acceptable to First Choice. Each Phase I ESA and report on ACM (an “ACM report”) shall be delivered in counterparts to Enterprise and First Choice. The Environmental Consultant will include customary language allowing both Enterprise and First Choice to rely upon its findings and conclusions. The Environmental Consultant will provide a draft of any Phase I ESA to First Choice and Enterprise for review and comment prior to the finalization of such report. Notwithstanding the foregoing, except as set forth in this Section, neither Enterprise nor the Environmental Consultant will conduct or cause to be conducted any invasive, intrusive or destructive inspections or other sampling or testing on the First Choice Leased Property, including, without limitation, of the air, soil, soil gas, vapors, surface water, groundwater, building materials or other environmental media, thereon.

(b) Phase II Assessments. In the event any Phase I ESA or ACM report (including a Phase I ESA that First Choice or any First Choice Subsidiary caused to be performed within one (1) year prior to the date of this Agreement) discloses that property subject to such Phase I ESA or ACM report may be impacted or have its use restricted by any Recognized Environmental Condition or Historical Recognized Environmental Condition (as each term is defined by ASTM E1527-13), any PFAS, or any ACM for which First Choice or any First Choice Subsidiary would be liable before the Effective Time and which, in the good faith reasonable belief of Enterprise, would result in a material liability to the Surviving Entity or EB&T (as the surviving bank in the Bank Merger) following the Effective Time and as such warrants further review or investigation, Enterprise shall give notice of the same (a “Phase I Notice”) to First Choice no later than five (5) Business Days following Enterprise’s receipt of the relevant Phase I ESA and ACM report. First Choice may then, in its sole and absolute discretion and without any obligation whatsoever to do so, within an additional twenty (20) day period, retain the Environmental Consultant to conduct a Phase II environmental site assessment in accordance with ASTM Standard E1903-11 (“Phase II ESA”) of, and to sample for ACM at, the relevant property or facility; provided, however, that such Phase II ESA and sampling for ACM shall be completed, and a written report of the Phase II ESA and of the analytical results of any sampling for ACM prepared, no later than sixty (60) days after First Choice receives from Enterprise the Phase I Notice for the relevant property; and provided further, that with respect to any First Choice Leased Property, First Choice will use Commercially Reasonable Efforts to obtain the relevant property owner’s consent for such Phase II ESA. Enterprise acknowledges and understands that such consent may not be able to be obtained. The scope of the Phase II ESA and of any sampling for ACM shall be mutually determined by Enterprise and First Choice in their reasonable discretion after consultation with the other party, and all reasonable costs and expenses associated with such Phase II ESA and ACM sampling and associated reports shall be borne by Enterprise. First Choice shall provide copies of the draft and final Phase II ESA and ACM reports, if any, to Enterprise promptly following the receipt of any such report(s) by First Choice.

(c) Remediation Estimates. In the event any Phase II ESA or ACM report confirms the presence of any ACM or of environmental contamination, including, without limitation, a release or threat or release from an abandoned underground storage tank or the presence of other Hazardous Substances, in each case present in concentrations above applicable standards under applicable Environmental Laws or that, based on the reasonable determination of the Environmental Consultant, would, or would reasonably be expected to, threaten human health or the environment, or if First Choice chooses not to conduct Phase II ESA and ACM report as reasonably requested by Enterprise pursuant to Section 5.18(b), Enterprise may elect to require First Choice to obtain, prior to the Closing Date and as soon as reasonably practical but in no event more than sixty (60) days after Enterprise receives the relevant Phase I ESA, Phase II ESA, or ACM report, and at First Choice’s sole cost and expense, from the Environmental Consultant or another nationally recognized contractor mutually acceptable to the parties, a written good faith estimate of the minimum cost and expense necessary to

TABLE OF CONTENTS

further investigate, remediate, cleanup, abate, restore, remove and otherwise address such Recognized Environmental Condition, Historical Recognized Environmental Condition, ACM or environmental contamination to the extent required by and in accordance with Environmental Laws and, to the extent required, to the satisfaction of any relevant Governmental Authority, assuming the continued commercial use of the relevant property and employing risk-based remedial standards and institutional controls where applicable (a “Remediation Estimate”). First Choice shall provide to Enterprise any Remediation Estimate requested within five (5) business days of First Choice’s receipt thereof. First Choice shall, upon Enterprise’s reasonable request, cause all Remediation Estimates to be updated through the Closing Date.

(d) Remediation Estimate Adjustment. Should the sum of all Remediation Estimates (to the extent the costs reflected in such estimates will or are reasonably expected to be incurred by First Choice or any First Choice Subsidiary, and taking into account any tax credits, deductions or benefits or insurance coverage or contributions by landlords or other third parties, in each case, that the parties agree is reasonably likely to be available to First Choice or any First Choice Subsidiary in connection with the incurrence of such costs) (such sum, the “Aggregate Remediation Estimate”) exceeds $3,000,000 in the aggregate (the “Remediation Deductible”), Enterprise may elect by written notice to adjust the original Exchange Ratio to a number equal to 0.6603 (i.e., the original Exchange Ratio), minus the Remediation Estimate Adjustment. The “Remediation Estimate Adjustment” is a number equal to the quotient, (A) the numerator of which is the product of (i) the amount by which the Aggregate Remediation Estimate exceeds the Remediation Deductible and (ii) 0.75 (i.e., 1 — a 25% tax rate), and (B) the denominator of which is the product of (i) 11,824,487 (i.e., the issued and outstanding shares of First Choice Common Stock as of March 31, 2021) and (ii) the Initial VWAP. An example of the calculation of the Remediation Estimate Adjustment and the resulting adjusted Exchange Ratio is set forth in Schedule 3.

(e) Cooperation. Notwithstanding anything in this Section 5.18 to the contrary, First Choice shall keep Enterprise reasonably apprised of all activities and actions contemplated by this Section 5.18, and First Choice and Enterprise shall cooperate fully with one another with respect to the matters required by this Section 5.18.

Section 5.19 Certain Litigation. First Choice shall promptly advise Enterprise orally and in writing of any actual or threatened Legal Proceeding against First Choice and/or the members of the First Choice Board related to this Agreement or the Merger and the other transactions contemplated by this Agreement. First Choice shall: (i) permit Enterprise to review and discuss in advance, and consider in good faith the views of Enterprise in connection with, any proposed written or oral response to such Legal Proceeding; (ii) furnish Enterprise’s outside legal counsel with all non-privileged information and documents which outside counsel may reasonably request in connection with such Legal Proceeding; (iii) consult with Enterprise regarding the defense or settlement of any such Legal Proceeding, give due consideration to Enterprise’s advice with respect to such Legal Proceeding and not settle any such Legal Proceeding prior to such consultation and consideration; provided, however, that First Choice shall not settle any such Legal Proceeding if such settlement requires the payment of money damages, without the written consent of Enterprise (such consent not to be unreasonably withheld or delayed) unless the payment of any such damages by First Choice is reasonably expected by First Choice, following consultation with outside counsel, to be fully covered (disregarding any deductible to be paid by First Choice) under First Choice’s existing director and officer insurance policies, including any tail policy.

Section 5.20 Director Matters; Board Packages. First Choice shall use Commercially Reasonable Efforts to cause to be delivered to Enterprise resignations of all the directors of First Choice and First Choice Subsidiaries, such resignations to be effective as of the Effective Time. First Choice shall distribute by electronic email or otherwise make available a copy of any First Choice or First Choice Bank board package, including the agenda, any draft minutes and any reports (including any internal management financial control reports showing actual financial performance against plan and previous period, and reports relating to financial performance and risk management), to Enterprise as soon as practicable after the time in which it distributes a copy of such package to the First Choice Board and board of directors of First Choice Bank, as the case may be (and in any event at least two Business Days prior to the board meeting for which the board package relates); provided, however, that First Choice shall not be required to disclose

First Choice shall permit representatives of Enterprise to be onsite at First Choice to facilitate integration of operations and assist with any other coordination efforts as necessary.

(b) First Choice shall, consistent with GAAP and regulatory accounting principles, use Commercially Reasonable Efforts to adjust, at Enterprise’s reasonable request, internal control procedures which are consistent with Enterprise’s and EB&T’s current internal control procedures to allow Enterprise to fulfill its reporting requirement under Section 404 of the Sarbanes-Oxley Act, provided, however, that no such adjustments need be made prior to the satisfaction of the conditions set forth in Section 6.01(a) and Section 6.01(b).

In addition, after satisfaction of the conditions set forth in Section 6.01(a) and Section 6.01(b), each party shall, upon the reasonable request of the other party, introduce the other party and its representatives to its customers and those of its Subsidiaries for the purpose of facilitating the integration of First Choice and its business into that of Enterprise. Any interaction between Enterprise and First Choice and any of their Subsidiaries’ customers and suppliers shall be coordinated by the parties and no discussions, meetings or communications between a party’s customers and suppliers shall occur without the presence of a representative of, or the prior written approval of, such party.

(e) First Choice Bank shall execute such certificates or articles of combination and such other documents and certificates as may be requested by Enterprise to effectuate the Bank Merger.

Section 5.22 Confidentiality.

ARTICLE 7
TERMINATION

Section 7.01 Termination. This Agreement may be terminated, and the transactions contemplated hereby may be abandoned:

(a) Mutual Consent. At any time prior to the Effective Time, by the mutual consent, in writing, of Enterprise and First Choice.

(b) No Regulatory Approval. By Enterprise or First Choice in the event any Closing Regulatory Approval (i) shall have been denied by final, non-appealable action by the applicable Governmental Authority or an application therefor shall have been withdrawn at the request of the applicable Governmental Authority, (ii) any Closing Regulatory Approval includes a Burdensome Condition, or (iii) any court of competent jurisdiction or other Governmental Authority shall have issued an order, decree, ruling or taken any other action restraining or enjoining or otherwise prohibiting the transactions contemplated by this Agreement and such order, decree, ruling or other action shall have become final and non-appealable; provided, however, that no party shall have the right to terminate this Agreement pursuant to this Section 7.01(b) if such denial shall be due to the failure of the party seeking to terminate this Agreement to perform or observe the covenants of such party set forth in this Agreement.

(c) Reduced Valuation. By First Choice by delivering written notice to Enterprise at any time during the five (5) Trading Day period commencing on the Determination Date if both of the following conditions are satisfied: (i) the Average VWAP as of the Trading Day immediately preceding Determination Date is less than 0.80 of the Initial VWAP (such Average VWAP, the “Triggering VWAP”); and (ii) the quotient obtained by dividing the Triggering VWAP by the Initial VWAP (rounding to four decimal places) is less than the quotient obtained by dividing the Final Index Price by the Initial Index Price (rounded to four decimal places) (such quotient, the “Index Ratio”), and then subtracting 0.20 from the Index Ratio; provided, however, that if First Choice elects to terminate pursuant to this Section 7.01(c) and provides such written notice to Enterprise, then within two (2) Business Days following Enterprise’s receipt of such notice, Enterprise may elect by written notice to First Choice to reinstate the Merger and the other transactions contemplated by this Agreement and adjust the Exchange Ratio to equal a number equal to the lesser of (1) a quotient (rounded to the nearest one-thousandth), the numerator of which is 0.80 of the Initial VWAP, multiplied by the

A-59

TABLE OF CONTENTS

Exchange Ratio, and the denominator of which is the Triggering VWAP and (2) a quotient (rounded to the nearest one-thousandth), the numerator of which is 0.80 of the Initial VWAP, multiplied by the Exchange Ratio, and the denominator of which is the Triggering VWAP, and then multiplying such quotient by the Index Ratio. An example of the calculations used to determine whether the two conditions set forth in clauses (i)-(ii) above have been satisfied (assuming no adjustment to the Exchange Ratio under Section 5.18(d)) is set forth in Schedule 4. If Enterprise makes such election to reinstate the Merger and the other transactions contemplated by this Agreement, no termination will occur pursuant to this Section 7.01(c) and this Agreement will remain in effect according to its terms (except as the Merger Consideration has been adjusted). If Enterprise, during such time as it belongs to the Index, declares or effects a stock split, stock dividend, recapitalization, reclassification, or similar transaction with respect to the outstanding Enterprise Common Stock, and the record date therefor shall be after the date of this Agreement and prior to the Determination Date, the prices for the Enterprise Common Stock shall be proportionately and appropriately adjusted for the purpose of applying this Section 7.01(c).

(d) No Shareholder Approval.

Nothing in this Agreement (a) will limit or affect any actions or omissions taken by Shareholder in Shareholder’s capacity as a director or officer, including in exercising rights under the Merger Agreement, and no such actions or omissions shall be deemed a breach of this Agreement or (b) will be construed to prohibit, limit or restrict Shareholder from exercising fiduciary duties as an officer or director to First Choice or its shareholders.

I am under no disability or impairment that affects my decision to sign this Consent and I knowingly and voluntarily intend to be legally bound by this Consent. I consent to the delivery and transmission of this Consent (and the Voting Agreement, as applicable) by facsimile, by electronic mail, or by other electronic transmission, and to the use of portable document format (.pdf) or other electronic or facsimile format for this Consent and the Voting Agreement (as applicable).

Enterprise Financial Services Corp, a corporation organized and existing under and by virtue of the General Corporation Law of the State of Delaware (the “Corporation”), does hereby certify that the following amendment to the Certificate of Incorporation of said Corporation has been duly adopted in accordance with the provisions of Section 242 of the General Corporation Law of the State of Delaware:

1. The name of the Corporation is Enterprise Financial Services Corp. The date of the filing of its original Certificate of Incorporation with the Secretary of State of the State of Delaware was December 30, 1994, under the name Enterbank Holdings, Inc.

2. Article FOUR of the Certificate of Incorporation of the Corporation, as amended, is amended to read in its entirety as follows:

“The aggregate number of shares of all classes of capital stock which the corporation shall have the authority to issue shall be eighty million (80,000,000) shares divided into two classes as follows:

(a) Five million (5,000,000) shares of preferred stock having par value of $.01 per share (the “Preferred Stock”); and

(b) seventy-five million (75,000,000) shares of common stock having par value of $.01 per share (the “Common Stock”).

The Board of Directors of the corporation shall be authorized, subject to any limitations prescribed by the law of the State of Delaware, to provide in a resolution or resolutions for the issuance of shares of the Preferred Stock in one or more series, and, by filing a Certificate of Designation pursuant to the applicable law of the State of Delaware (a “Preferred Stock Designation”), to establish from time to time the number of shares to be included in each such series and to fix the designations, powers, preferences and relative, participating, optional or other rights, if any, and the qualifications, limitations or restrictions thereof, if any. The authority of the Board of Directors of the corporation with respect to each series of the Preferred Stock shall include, but not be limited to, determination of the following:

(A) the number of shares constituting that class or series and the distinctive designation of that series;

(B) the dividend rate on the shares of that series, whether dividends shall be cumulative, and, if so, from which date or dates, and the relative rights of priority, if any, of payment of dividends on shares of that series;

(C) whether that series shall have voting rights, in addition to the voting rights provided by law, and, if so, the terms and conditions of such voting rights, including, without limitation, whether such series shall have the right to vote as a separate class and/or vote on a cumulative or noncumulative basis;

(D) whether that series shall have conversion privileges, and, if so, the terms and conditions of such conversion including provision for adjustment of the conversion rate upon the occurrence of such events as the Board of Directors of the corporation shall determine;

(E) whether the shares of that series shall be redeemable, and, if so, the terms and conditions of such redemption, including the date or dates upon or after which they shall be redeemable, and the amount per share payable in case of redemption, which amount may vary under different conditions and at different redemption dates;

(F) whether that series shall have a sinking fund for the redemption or purchase of shares of the series, and, if so, the terms and amount of such sinking fund;

C-1

(G) the rights and/or preferences of the shares of that series in the event of the voluntary or involuntary liquidation, dissolution or winding up of the corporation, and the relative rights of priority, if any, of payment in respect of shares of that series; and

(H) any other relative rights, preferences and limitations of that series.

The Board of Directors of the corporation is expressly authorized to adopt such resolution or resolutions and issue such Preferred Stock from time to time as it may deem desirable. The Board of Directors of the corporation is further expressly authorized to increase (but not above the total number of authorized shares of the class) or decrease (but not below the number of shares of any such series then outstanding) the number of shares of any series of Preferred Stock, the number of which is fixed by it, subsequent to the issuance of shares then outstanding, subject to the powers, preferences and rights, and the qualifications, limitations and restrictions thereof stated in this Certificate of Incorporation or the resolution or resolutions of the Board of Directors of the corporation originally fixing the number of shares of such series. If the number of shares of any series of Preferred Stock is so decreased, then the shares constituting such decrease shall resume the status which they had prior to the adoption of the resolution or resolutions originally fixing the number of shares of such series of Preferred Stock. The number of authorized shares of Common Stock or Preferred Stock may be increased or decreased (but not below the number of shares of such class then outstanding) by the vote of a majority of the outstanding shares of stock entitled to vote thereon, and no separate class vote of either the Common Stock or the Preferred Stock shall be required to effect any such amendment.

The shares of the authorized Common Stock shall be identical in all respects and shall have equal rights and privileges, subject only to the senior rights applicable to the Preferred Stock or any series thereof. Except as may be provided in this Certificate of Incorporation or in a Preferred Stock Designation or by applicable law of the State of Delaware, holders of the Preferred Stock shall not be entitled to receive notice of any meeting of stockholders at which they are not entitled to vote, holders of the Common Stock shall have the exclusive right to vote for the election of Directors of the corporation and for all other purposes, and holders of shares of the Common Stock shall be entitled to one vote for each such share upon all questions presented to the stockholders of the corporation. Holders of the Common Stock shall not have the right to cumulate votes in the election of Directors of the corporation. Holders of shares of the Common Stock shall at all times, except as otherwise provided in this Certificate of Incorporation or as required by the law of the State of Delaware, vote as one class, together with the holders of any other class or series of stock of the Corporation accorded such general voting rights.”

3. All other provisions of the Certificate of Incorporation shall remain in full force and effect.

4. This Certificate of Amendment to the Certificate of Incorporation was approved by the holders of the requisite number of shares of the Corporation in accordance with Sections 228 and 242 of the Delaware General Corporation Law.

Board of Directors
Enterprise Financial Services Corp
150 North Meramec Avenue
Clayton, Missouri 63105

Members of the Board of Directors:

You have requested our opinion as to the fairness, from a financial point of view, to Enterprise Financial Services Corp, a Delaware corporation (“Enterprise”), of the Exchange Ratio (as defined below) in the proposed merger (the “Proposed Merger”) by and among Enterprise, Enterprise Bank & Trust, a Missouri state-chartered trust company (“EB&T”), First Choice Bancorp, a California corporation (“First Choice”) and First Choice Bank, a California chartered commercial bank (“First Choice Bank”), as set forth in the Agreement and Plan of Merger dated April 26, 2021 (the “Merger Agreement”). As detailed in the Merger Agreement, First Choice will merge with and into Enterprise, with Enterprise as the surviving entity, and thereafter First Choice Bank will merge with and into EB&T, with EB&T as the surviving entity. Each share of First Choice common stock, no par value per share (“First Choice Common Stock”), issued and outstanding (other than (i) First Choice Common Stock that is owned directly by Enterprise, First Choice or any of their subsidiaries as treasury stock or otherwise (other than shares held in trust accounts, managed accounts and the like for the benefit of customers) or (ii) First Choice Common Stock as to which dissenters’ rights are perfected under California General Corporation Law), including all outstanding restricted stock awards and other stock-based awards granted by First Choice, shall be cancelled and converted into the right to receive 0.6603 shares of Enterprise common stock, par value $0.01 (“Enterprise Common Stock”) (the “Exchange Ratio”) as set forth in the Merger Agreement.

Boenning & Scattergood, Inc., as part of its investment banking business, regularly is engaged in the valuation of assets, securities and companies in connection with various types of asset and security transactions, including mergers, acquisitions, private placements, public offerings and valuations for various other purposes, and in the determination of adequate consideration in such transactions. In the ordinary course of our business as a broker-dealer, we may, from time to time, purchase securities from, and sell securities to, Enterprise and First Choice or their respective affiliates. In the ordinary course of business, we may also actively trade the securities of Enterprise and First Choice for our own account and for the accounts of customers and accordingly may at any time hold a long or short position in such securities.

We have acted as financial advisor to the Board of Directors of Enterprise solely in connection with the Proposed Merger and will receive a fee for our services, a significant portion of which is contingent upon consummation of the Proposed Merger. A portion of our fee is payable upon rendering this opinion. Our fee for rendering this opinion is not contingent upon any conclusion that we may reach. Enterprise has also agreed to indemnify us against certain liabilities arising out of our engagement and to reimburse us for certain expenses incurred in connection with our engagement.

Boenning & Scattergood, Inc. served as exclusive financial advisor to Enterprise in its acquisition of Seacoast Commerce Banc Holdings in 2020 and received a customary fee for its services. Boenning & Scattergood, Inc. has not had any material investment banking relationship with First Choice during the past two years in which compensation was received or was intended to be received as a result of the relationship between Boenning & Scattergood, Inc., on the one hand, and First Choice, on the other hand. Boenning & Scattergood, Inc. may provide investment banking services to Enterprise in the future, although there is no

agreement to do so. Additionally, to the extent the Proposed Merger is not consummated, Boenning & Scattergood, Inc. may provide investment banking services to First Choice in the future, although there is no agreement to do so.

In arriving at our opinion, we have, among other things: (i) reviewed the historical financial performances, current financial positions and general prospects of Enterprise and First Choice and their respective subsidiaries and reviewed certain “Street” consensus estimates, (ii) reviewed a draft of the Merger Agreement dated April 26, 2021 (the most recent draft made available to us), (iii) reviewed and analyzed the stock market performance and trading history of Enterprise Common Stock and First Choice Common Stock, and compared those trading histories with the trading histories of certain other publicly traded companies we deemed relevant, (iv) compared certain financial and stock market information of Enterprise and First Choice with similar publicly available information of certain other companies we deemed relevant, (v) reviewed and analyzed the consolidated financial and operating data of Enterprise and First Choice, (vi) reviewed the pro forma financial impact of the Proposed Merger on Enterprise, based on assumptions relating to transaction expenses, purchase accounting adjustments, cost savings and other synergies determined and provided by the respective senior management teams of Enterprise and First Choice, and relied upon by us at the direction of such management and with the consent of Enterprise, (vii) considered the nature and financial terms of the Proposed Merger as compared with the nature and financial terms of certain other merger transactions and business combinations in the banking industry, (viii) met and/or communicated with certain members of Enterprise’s and First Choice’s senior management to discuss their respective businesses, operations, historical financial statements and future prospects, and (ix) conducted such other financial analyses, studies and investigations as we deemed appropriate and have taken into account our assessment of general economic, market and financial conditions and our experience in other transactions, as well as our experience in securities valuation and knowledge of the banking industry generally.

In conducting our review and arriving at our opinion, we have relied on the accuracy and completeness of all financial and other information made or given by Enterprise and First Choice, and their respective officers, directors, auditors, counsel and other agents, and on publicly available filings, releases and other information relating to Enterprise and First Choice, including financial statements, financial projections, and stock price data as well as certain information from recognized independent sources. We have not independently verified the information concerning Enterprise and First Choice or other data which we have considered in our review and, for purposes of the opinion set forth below, we have assumed and relied upon the accuracy and completeness of all such information and data. We have assumed, at the direction of Enterprise, that all forecasts and projections provided to us have been reasonably prepared and reflect the best currently available estimates and good faith judgments of the management of Enterprise and First Choice as to their most likely future financial performance. We express no opinion as to any financial projections or the assumptions on which they are based. We have not conducted any valuation or appraisal of any assets or liabilities of Enterprise or First Choice, nor have any such valuations or appraisals been provided to us. Additionally, we assume that the Proposed Merger is, in all respects, lawful under applicable law.

With respect to anticipated transaction costs, purchase accounting adjustments, expected cost savings and other synergies and financial and other information relating to the general prospects of Enterprise and First Choice, we have assumed, based on discussions with Enterprise’s management and with the consent of Enterprise, that such information, projections and estimates have been reasonably prepared and reflect the best currently available estimates and judgment of the respective management teams of Enterprise and First Choice as to their most likely future performance. It is understood that the foregoing financial information of Enterprise and First Choice that was provided to us was not prepared with the expectation of public disclosure, that all of the foregoing financial information of Enterprise and First Choice referred to above, is based on numerous variables and assumptions that are inherently uncertain, including, without limitation, factors related to general economic and competitive conditions and that, accordingly, actual results could

vary significantly from those set forth in such information. We have further relied on the assurances of management of Enterprise and First Choice that they are not aware of any facts or circumstances that would make any of such information inaccurate, incomplete or misleading in any material respect. 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 have assumed that the allowances for credit or loan losses indicated on the balance sheets of Enterprise and First Choice are adequate to cover such losses and comply fully with applicable law, regulatory policy and sound banking practices; we have not reviewed individual loans or credit files of Enterprise or First Choice. We have assumed that the representations and warranties of all parties contained in the Merger Agreement and all related agreements and documents are true and correct, that each party under such agreements and documents will perform all of the covenants required to be performed by such party under such agreements and documents, and that the conditions precedent in such agreements and documents are not waived. We have assumed that the Merger Agreement (the final terms of which we have assumed will not differ in any respect material to our analyses from the draft version reviewed by us and referred to above) represents the entire agreement between the parties, that it has not been modified or amended, and that its terms have not been superseded or supplemented by other agreements or documents, the effect of which would be in any way meaningful to our analysis. We have assumed that there have been no adjustments to the Exchange Ratio and there is no other consideration or payments that will be made under the Merger Agreement in respect of First Choice Common Stock. Also, in rendering our opinion, we have assumed that in the course of obtaining the necessary regulatory approvals for the consummation of the Proposed Merger, no conditions will be imposed that will materially affect either Enterprise or First Choice, the combined entity or the contemplated benefits of the Proposed Merger, including the cost savings and related expenses expected to result from the Proposed Merger in any way meaningful to our analysis. We have also assumed, with your consent, that the Proposed Merger will be treated as a tax-free reorganization for federal income tax purposes. We have assumed that the Proposed Merger will be consummated in a manner that complies with the applicable provisions of the Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as amended, and all other applicable federal and state statutes, rules and regulations.

Our opinion is based solely upon (i) information provided to us by Enterprise and First Choice and their respective officers, directors, auditors, counsel and other agents; (ii) public filings, releases and other information issued by Enterprise and First Choice including financial statements, financial projections, and stock price data as well as certain information from recognized independent sources; and (iii) market, economic, financial and other conditions as they exist and can be evaluated only as of the date hereof and, accordingly, it speaks to no other period. We have not undertaken to reaffirm or revise this opinion or otherwise comment on events occurring after the date hereof and do not have an obligation to update, revise or reaffirm our opinion. This opinion addresses only the fairness, from a financial point of view, to Enterprise, as of the date hereof, of the Exchange Ratio in the Proposed Merger. Our opinion does not address the relative merits of the Proposed Merger and the other business strategies that Enterprise’s Board of Directors has considered or may be considering, nor does it address the underlying business decision of Enterprise’s Board of Directors to proceed with the Proposed Merger. We are expressing no opinion as to the prices at which Enterprise’s securities or First Choice’s securities may trade at any time. Nothing in our opinion is to be construed as constituting tax advice or a recommendation to take any particular tax position, nor does our opinion address any legal, tax, regulatory or accounting matters, as to which we understand that Enterprise has obtained such advice as it deemed necessary from qualified professionals. We are not expressing any opinion as to the impact of the Proposed Merger on the solvency or viability of Enterprise or First Choice or the ability of Enterprise or First Choice, or their respective subsidiaries, to pay their respective obligations when they come due. Our opinion is for the information of Enterprise’s Board of Directors in connection with its evaluation of the Proposed Merger and does not constitute a recommendation to Enterprise’s Board of Directors in connection with the Proposed Merger. This opinion should not be construed as creating any fiduciary duty on Boenning & Scattergood, Inc.’s part to any party or person. Our opinion is not to be quoted or referred to, in whole or in part, in a registration statement, prospectus,

proxy statement or in any other document, nor shall this opinion be used for any other purpose, without our prior written consent, except that, if required by applicable law, this opinion may be referenced and included, in its entirety, in any filing made by Enterprise with the Securities and Exchange Commission with respect to the Proposed Merger; provided, however, that any description of, or reference to, our opinion, or to Boehning & Scattergood, Inc., shall be in a form reasonably acceptable to us and to our counsel. We shall have no responsibility for the form or content of any such disclosure, other than the opinion itself.

This opinion has been approved by Boenning & Scattergood, Inc.’s fairness opinion committee in accordance with our written procedures for approval of fairness opinions. We have not been requested to opine as to, and this opinion does not express an opinion or otherwise address, among other things, (i) the fairness of the Proposed Merger to the holders of any class of securities, creditors, or other constituencies of Enterprise or First Choice, or to any other party, except as set forth in the last sentence of this opinion or (ii) the fairness of the Proposed Merger to any one class or group of Enterprise’s, First Choice’s, or any other party’s security holders or other constituencies vis-à-vis any other class or group of Enterprise’s, First Choice’s, or such other party’s security holders or other constituents (including, without limitation, the allocation of any consideration to be received in the Proposed Merger among or within such classes or groups of security holders or other constituents). Further, we do not express any opinion as to the fairness of the amount or nature of the compensation to be received in the Proposed Merger by the officers, directors, or employees of any party to the Merger Agreement, or any class of such persons, relative to the compensation to be received by the holders of First Choice Common Stock in the Proposed Merger.

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

Sincerely,

Boenning & Scattergood, Inc.

Cerritos, CA 90703

Members of the Board:

You have requested the opinion of Keefe, Bruyette & Woods, Inc. (“KBW” or “we”) as investment bankers as to the fairness, from a financial point of view, to the common shareholders of First Choice Bancorp (“First Choice”) of the Exchange Ratio (as defined below) in the proposed merger (the “Merger”) of First Choice with and into Enterprise Financial Services Corp (“Enterprise”) pursuant to the Agreement and Plan of Merger (the “Agreement”) to be entered into by and among First Choice, First Choice Bank (“FCB”), a wholly-owned subsidiary of First Choice, Enterprise, and Enterprise Bank & Trust (“EB&T”), a wholly-owned subsidiary of Enterprise. Pursuant to the Agreement and subject to the terms, conditions and limitations set forth therein, at the Effective Time (as defined in the Agreement), automatically by virtue of the Merger and without any action on the part of Enterprise, First Choice or any shareholder of First Choice, each share of common stock, no par value per share, of First Choice (“First Choice Common Stock”) issued and outstanding immediately prior to the Effective Time, other than shares of First Choice Common Stock owned directly by Enterprise, First Choice or any of their respective subsidiaries, as treasury stock or otherwise (other than shares in trust accounts, managed accounts, and the like for the benefit of customers) and Dissenting Shares (as defined in the Agreement), shall be converted into the right to receive 0.6603 of a share of common stock, par value $0.01 per share, of Enterprise (the “Enterprise Common Stock”). The ratio of 0.6603 of a share of Enterprise Common Stock for one share of First Choice Common Stock is referred to herein as the “Exchange Ratio.” The terms and conditions of the Merger are more fully set forth in the Agreement.

The Agreement further provides that, at such time following the Effective Time as Enterprise may determine, FCB will merge with and into EB&T with EB&T as the surviving entity, pursuant to a separate plan of bank merger (such transaction, the “Bank Merger”).

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

Other than in connection with this present engagement, KBW has not provided investment banking or financial advisory services to First Choice or Enterprise during the past two years. We may in the future

provide investment banking and financial advisory services to First Choice or Enterprise and receive compensation for such services.

In connection with this opinion, we have reviewed, analyzed and relied upon material bearing upon the financial and operating condition of First Choice and Enterprise and bearing upon the Merger, including among other things, the following: (i) a draft of the Agreement dated April 20, 2021 (the most recent draft made available to us); (ii) the audited financial statements and the Annual Reports on Form 10-K for the three fiscal years ended December 31, 2020 of First Choice; (iii) certain preliminary and unaudited quarterly financial results for the quarter ended March 31, 2021 of First Choice (provided by First Choice); (iv) the audited financial statements and Annual Reports on Form 10-K for the three fiscal years ended December 31, 2020 of Enterprise; (v) certain preliminary and unaudited quarterly financial results for the quarter ended March 31, 2021 of Enterprise (provided by Enterprise); (vi) certain regulatory filings of First Choice and Enterprise and their respective subsidiaries, including the quarterly reports on Form FR Y-9C and call reports filed with respect to each quarter during the three-year period ended December 31, 2020; (vii) certain other interim reports and other communications of First Choice and Enterprise to their respective shareholders or stockholders; and (viii) other financial information concerning the businesses and operations of First Choice and Enterprise that was furnished to us by First Choice and Enterprise or that we were otherwise directed to use for purposes of our analyses. Our consideration of financial information and other factors that we deemed appropriate under the circumstances or relevant to our analyses included, among others, the following: (i) the historical and current financial position and results of operations of First Choice and Enterprise; (ii) the assets and liabilities of First Choice and Enterprise; (iii) the nature and terms of certain other merger transactions and business combinations in the banking industry; (iv) a comparison of certain financial and stock market information for First Choice and Enterprise with similar information for certain other companies the securities of which are publicly traded; (v) publicly available consensus “street estimates” of First Choice, as well as assumed long-term First Choice growth rates provided to us by First Choice management, all of which information was discussed with us by First Choice management and used and relied upon by us at the direction of such management and with the consent of the Board; (vi) publicly available consensus “street estimates” of Enterprise, as well as assumed long-term Enterprise growth rates provided to us by Enterprise management, all of which information was discussed with us by Enterprise management and used and relied upon by us based on such discussions, at the direction of First Choice management and with the consent of the Board; and (vii) estimates regarding certain pro forma financial effects of the Merger on Enterprise (including, without limitation, the cost savings and related expenses expected to result or be derived from the Merger) that were prepared by, and provided to and discussed with us by, Enterprise management and that were used and relied upon by us based on such discussions, at the direction of First Choice management and with the consent of the Board. We have also performed such other studies and analyses as we considered appropriate and have taken into account our assessment of general economic, market and financial conditions and our experience in other transactions, as well as our experience in securities valuation and knowledge of the banking industry generally. We have also participated in discussions held by the managements of First Choice and Enterprise regarding the past and current business operations, regulatory relations, financial condition and future prospects of their respective companies and such other matters as we have deemed relevant to our inquiry. We have not been requested to assist, and have not assisted, First Choice with soliciting indications of interest from third parties regarding a potential transaction with First Choice.

In conducting our review and arriving at our opinion, we have relied upon and assumed the accuracy and completeness of all of the financial and other information that was provided to us or that was publicly available and we have not independently verified the accuracy or completeness of any such information or assumed any responsibility or liability for such verification, accuracy or completeness. We have relied upon the management of First Choice as to the reasonableness and achievability of the publicly available consensus “street estimates” of First Choice and the assumed First Choice long-term growth rates referred to above (and the assumptions and bases therefor), and we have assumed that all such information has been reasonably prepared and represents, or in the case of the First Choice “street estimates” referred to above that such estimates are consistent with, the best currently available estimates and judgments of First Choice management

and that the forecasts, projections and estimates reflected in such information will be realized in the amounts and in the time periods currently estimated. We have further relied, with the consent of First Choice, upon Enterprise management as to the reasonableness and achievability of the publicly available consensus “street estimates” of Enterprise, the assumed Enterprise long-term growth rates, and the estimates regarding certain pro forma financial effects of the Merger on Enterprise (including, without limitation, the cost savings and related expenses expected to result or be derived from the Merger), all as referred to above (and the assumptions and bases for all such information), and we have assumed that all such information has been reasonably prepared and represents, or in the case of the Enterprise “street estimates” referred to above that such estimates are consistent with, the best currently available estimates and judgments of Enterprise management and that the forecasts, projections and estimates reflected in such information will be realized in the amounts and in the time periods currently estimated.

It is understood that the portion of the foregoing financial information of First Choice and Enterprise that was provided to us was not prepared with the expectation of public disclosure and that all of the foregoing financial information, including the publicly available consensus “street estimates” of First Choice and Enterprise, is based on numerous variables and assumptions that are inherently uncertain (including, without limitation, factors related to general economic and competitive conditions and, in particular, assumptions regarding the ongoing COVID-19 pandemic) and, accordingly, actual results could vary significantly from those set forth in such information. We have assumed, based on discussions with the respective managements of First Choice and Enterprise and with the consent of the Board, that all such information provides a reasonable basis upon which we could form our opinion and we express no view as to any such information or the assumptions or bases therefor. Among other things, such information has assumed that the ongoing COVID-19 pandemic could have an adverse impact on First Choice and Enterprise. We have relied on all such information without independent verification or analysis and do not in any respect assume any responsibility or liability for the accuracy or completeness thereof. We also have assumed that there have been no material changes in the assets, liabilities, financial condition, results of operations, business or prospects of either First Choice or Enterprise since the date of the last financial statements of each such entity that were made available to us. We are not experts in the independent verification of the adequacy of allowances for loan and lease losses and we have assumed, without independent verification and with your consent, that the aggregate allowances for loan and lease losses for First Choice and Enterprise are adequate to cover such losses. In rendering our opinion, we have not made or obtained any evaluations or appraisals or physical inspection of the property, assets or liabilities (contingent or otherwise) of First Choice or Enterprise, the collateral securing any of such assets or liabilities, or the collectability of any such assets, nor have we examined any individual loan or credit files, nor did we evaluate the solvency, financial capability or fair value of First Choice or Enterprise under any state or federal laws, including those relating to bankruptcy, insolvency or other matters. Estimates of values of companies and assets do not purport to be appraisals or necessarily reflect the prices at which companies or assets may actually be sold. Such estimates are inherently subject to uncertainty and should not be taken as our view of the actual value of any companies or assets.

We have assumed, in all respects material to our analyses, the following: (i) that the Merger and any related transactions (including, without limitation, the Bank Merger) will be completed substantially in accordance with the terms set forth in the Agreement (the final terms of which we have assumed will not differ in any respect material to our analyses from the draft reviewed by us and referred to above), with no adjustments to the Exchange Ratio and with no other consideration or payments in respect of First Choice Common Stock; (ii) that the representations and warranties of each party in the Agreement and in all related documents and instruments referred to in the Agreement are true and correct; (iii) that each party to the Agreement and all related documents will perform all of the covenants and agreements required to be performed by such party under such documents; (iv) that there are no factors that would delay or subject to any adverse conditions, any necessary regulatory or governmental approval for the Merger or any related transactions and that all conditions to the completion of the Merger and any related transactions will be satisfied without any waivers or modifications to the Agreement or any of the related documents; and (v) that in the course of obtaining the necessary regulatory, contractual, or other consents or approvals for the

E-3

TABLE OF CONTENTS

Merger and any related transactions, no restrictions, including any divestiture requirements, termination or other payments or amendments or modifications, will be imposed that will have a material adverse effect on the future results of operations or financial condition of First Choice, Enterprise or the pro forma entity, or the contemplated benefits of the Merger, including without limitation the cost savings and related expenses expected to result or be derived from the Merger. We have assumed that the Merger will be consummated in a manner that complies with the applicable provisions of the Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as amended, and all other applicable federal and state statutes, rules and regulations. We have further been advised by representatives of First Choice that First Choice has relied upon advice from its advisors (other than KBW) or other appropriate sources as to all legal, financial reporting, tax, accounting and regulatory matters with respect to First Choice, Enterprise, the Merger and any related transaction and the Agreement. KBW has not provided advice with respect to any such matters.

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

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

INFORMATION NOT REQUIRED IN THE PROSPECTUS

Item 20. Indemnification of Directors and Officers

The following is a summary of relevant provisions of our certificate of incorporation, as amended, and certain provisions of the Delaware General Corporation Law, or the DGCL. We urge you to read the full text of these documents, forms of which have been filed with the U.S. Securities and Exchange Commission, or the SEC, as well as the referenced provisions of the DGCL because they are the legal documents and provisions that will govern matters of indemnification with respect to our directors and officers.

Enterprise is incorporated under the laws of the state of Delaware. Section 145 of the DGCL provides that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that he or she is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him or her in connection with such action, suit or 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. A similar standard is applicable in the case of derivative actions, except that indemnification only extends to expenses (including attorneys’ fees) incurred in connection with the defense or settlement of such action, and the statute requires court approval before there can be any indemnification where the person seeking indemnification has been found liable to the corporation.

The DGCL further provides that prior to any indemnification as detailed above, a corporation must authorize each case upon a determination that indemnification of the present or former director, officer, employee or agent is proper in the circumstances because the person has met the applicable standard of conduct. This determination must be made, with respect to a person who is a director or officer of the corporation at the time of such determination: (i) by a majority vote of the directors who are not parties to the action, suit or proceeding, even though less than a quorum, (ii) by a committee of such directors designated by majority vote of such directors, even though less than a quorum, or (iii) if there are no such directors, or if such directors so direct, by independent legal counsel in a written opinion, or (iv) by the stockholders.

The DGCL provides that such indemnification is not exclusive of any other rights to indemnification that may be granted by a corporation’s bylaws, disinterested director vote, stockholder vote, agreement or otherwise, with respect to an action in the person’s official capacity and as to action in another capacity while holding such office.

Enterprise’s certificate of incorporation, as amended, provides that Enterprise shall indemnity all of its directors and officers to the fullest extent permitted by the DGCL and as set forth in the bylaws. Enterprise’s amended and restated bylaws provide that Enterprise will indemnify any person who was or is a party or is threatened to be made a party to or is otherwise involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative by reason of the fact that such person is or was a director or officer of Enterprise or by reason of the fact that such person is or was serving at the request of Enterprise as a director, officer or trustee of another corporation, partnership, joint venture, trust, or other enterprise, against expense, liability and loss (including attorneys’ fees, judgments, fines, excise taxes or penalties and amounts paid or to be paid in settlement) reasonably incurred by such person in connection with such action, suit, or proceeding, but in each case only if and to the extent permitted under the DGCL. Indemnification under this provision will not be provided to any director, officer or representative that initiates such proceeding, unless such proceeding was authorized or consented to by the board of directors.

Item 22. Undertakings

(a) The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement (notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement); and (iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) That, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(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 issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form.

II-3

TABLE OF CONTENTS

(6) That every prospectus (i) that is filed pursuant to paragraph (5) immediately preceding, or (ii) that purports to meet the requirements of Section 10(a)(3) of the Securities Act of 1933 and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(7) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act of 1933 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 questions whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.

(b) The undersigned registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11 or 13 of 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.

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