PROXY STATEMENT FOR SPECIAL MEETING OF STOCKHOLDERS
To be held on Tuesday, November 25, 2008
 

INTRODUCTION

     We are sending this proxy statement to you as a stockholder of Enterprise Financial Services Corp, a Delaware corporation, in connection with the solicitation of proxies for a special meeting of stockholders of the Company’s Support Center at 1281 N. Warson Rd. St. Louis, MO 63132 on Tuesday, November 25, 2008, at 4:00 p.m. local time (the “Special Meeting”). The Company’s Board of Directors (the “Board of Directors”) is soliciting proxies for use at the Special Meeting and at any postponements or adjournments thereof. Only stockholders of the Company of record as of the close of business on October 27, 2008 (the “record date”) will be entitled to vote at the Special Meeting. The proxy solicitation materials for the Special Meeting were first mailed to stockholders of the Company on or about [November 7], 2008.

INFORMATION ABOUT THE SPECIAL MEETING

Why is the Company holding a Special Stockholders’ Meeting?

     The Company is holding a Special Meeting for purposes of voting on the following matters:

       1. 

to act on a proposed amendment to the Certificate of Incorporation of the Company to authorize the issuance of up to 5,000,000 shares of preferred stock of the Company having such designations, powers, preferences, rights, qualifications and limitations as the Board of Directors may from time to time fix by resolution adopted by the Board of Directors; and

 

       2. 

to conduct such other business as may properly come before the Special Meeting or any adjournments thereof.

When is the Special Meeting?

     Tuesday, November 25, 2008 at 4:00 p.m. local time.

Where will the Special Meeting be held?

     At the Company’s Support Center at 1281 N. Warson Rd. St. Louis, MO 63132.

Why is the amendment to the Certificate of Incorporation of the Company necessary?

     The Board of Directors believes that the authorization of preferred stock is advisable and in the best interests of the Company and its stockholders for several reasons. First, the Company is considering participating in the recently announced low-cost capital-raising opportunities from the United States Department of the Treasury intended to encourage financial institutions to increase the flow of financing to United States business and consumers and to support the United States economy. Although the Company’s capital position remains sound, the Board of Directors desires to consider the opportunity presented by the federal government and to maximize the Company’s ability to maintain its existing capital, take advantage of current market conditions and support its existing operations and anticipated future growth. Second, the authorization of the preferred stock would permit the Board of Directors to issue such stock without further stockholder approvals or delay and, thereby, provide the Company with maximum flexibility in participating in the federal government’s capital raising program, in structuring acquisitions, joint ventures, strategic alliances and capital-raising transactions, and for other corporate purposes. The preferred stock would enable the Company to respond promptly to and take advantage of market conditions and other favorable opportunities without incurring the delay and expense associated with calling a special meeting of the stockholders of the Company to approve a contemplated stock issuance. The Board of Directors believes that this will also help to reduce costs because it will not have to seek additional stockholder approval to issue the preferred shares unless it is required to obtain stockholder approval for the transaction under the rules of any quotation board or stock exchange to which it is subject. The Company presently contemplates no particular transaction


involving the issuance of preferred stock other than consideration of the federal government’s limited purchase of preferred stock in financial institutions such as the Company. However, the Board of Directors believes that preferred stock may be a component in future raising of capital for the benefit of the Company.

Who can vote at the Special Meeting?

     The Board of Directors has set October 27, 2008 as the record date for the Special Meeting. Common stock is the Company’s only class of voting securities. All stockholders who owned shares of the common stock of the Company at the close of business on the record date may attend and vote at the Special Meeting. On the record date, there were 12,726,975 shares of common stock of the Company outstanding. Shares of common stock of the Company held as of the record date include shares that are held directly in your name as the stockholder of record and those shares of common stock of the Company held for you as a beneficial owner through a stockbroker, bank or other nominee.

     Each stockholder of the Company is entitled to one vote for each share of common stock of the Company held on the record date.

How do I vote my shares of common stock of the Company?

     If your shares of common stock of the company 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 of common stock of the Company. As a stockholder of record, you have three options for voting your shares:

          1. vote via the Internet at www.proxyvote.com;

          2. vote via telephone toll-free at 1-800-690-6903; or

          3. complete and return the proxy card sent to you.

     For Internet or telephone voting, instructions are printed on the proxy card sent to you. You can revoke a proxy at any time prior to its exercise at the meeting by following the instructions in the accompanying proxy statement. Unless you instruct otherwise, your proxies will vote your shares FOR the amendment to the Certificate of Incorporation to authorize issuance of the preferred stock.

     If your shares are held in a stock brokerage account or by a bank or other nominee, you are still considered the beneficial owner of those shares of common stock of the Company, but your shares are said to be held in the “street name.” Generally, only stockholders of record may vote in person at the Special Meeting. If your shares are held in street name, you will receive a form from your broker, bank or other nominee seeking instruction as to how your shares should be voted. If you desire to vote shares held in street name in person at the Special Meeting, you need to contact your broker, bank or other nominee and ask how to obtain a “legal proxy” to directly vote such shares.

Can the proxy materials be accessed electronically?

     We are sending the proxy materials to stockholders on or about the date of this proxy statement by first-class U.S. mail. The proxy materials are also available on the Internet and can be accessed at enterprisebank.com.

May I change or revoke my proxy?

     Stockholders who execute proxies retain the right to revoke them at any time before they are exercised. Unless revoked, the shares represented by such proxies will be voted at the Special Meeting and all adjournments thereof. If you are the stockholder of record, you may change or revoke your proxy at any time before the Special Meeting by:

     
  • entering a new vote by Internet or telephone;
  • returning a later-dated proxy card;
  • sending written notice of revocation to the Secretary of the Company; and/or
  • attending the Special Meeting, notifying the Secretary of the Company of the revocation, and voting by ballot.


     A proxy will not be voted if a particular stockholder attends the Special Meeting and revokes his/her proxy by notifying the Secretary at the Special Meeting. Any stockholder who attends the Special Meeting and revokes his/her proxy may vote in person. However, your attendance at the Special Meeting alone will not revoke your proxy. Proxies solicited by the Company’s Board of Directors will be voted according to the directions given therein. Where no instructions are indicated, proxies will be voted FOR the amendment to the Certificate of Incorporation of the Company to authorize issuance of the preferred stock.

     To change your vote for shares you hold in street name, you will need to follow the instructions provided by your broker, bank or other nominee.

If I vote in advance can I still attend the Special Meeting?

     Yes. You are encouraged to vote promptly by Internet, telephone or by returning a proxy card by mail so that your shares will be represented at the Special Meeting. However, voting your shares does not affect your right to attend the Special Meeting and vote your shares in person.

How many votes must be present to hold the Special Meeting?

     There were 12,726,975 shares of the Company’s common stock issued and outstanding on the record date of October 27, 2008. The Company will have a quorum and will be able to conduct the business of the Special Meeting if the holders of a majority of the shares of the common stock of the Company entitled to vote are present at the Special Meeting, either in person or by proxy. If a quorum is not present at the time the Special Meeting is convened, the Company may adjourn or postpone the Special Meeting.

How many votes are required to approve the proposal?

     Each holder of common stock of the Company is entitled to one vote for each share of common stock of the Company held with respect to each matter to be voted upon. Approval of the proposed amendment to the Certificate of Incorporation of the Company to authorize the issuance of up to 5,000,000 shares of preferred stock of the Company requires a quorum and the affirmative vote of a majority of the shares of common stock of the Company outstanding as of the record date.

     An abstention from voting on a matter by a stockholder present in person or by proxy will have the same legal effect as a vote against the proposal to amend the Certificate of Incorporation of the Company to authorize the issuance of up to 5,000,000 shares of preferred stock of the Company. If a broker, bank or other nominee holder indicates on the proxy card that it does not have the discretionary authority to vote the shares of common stock of the Company it holds of record on the proposal, those shares will not be considered as present and entitled to vote on the proposal.

     All shares of common stock of the Company represented at the Special Meeting by properly executed proxies received prior to or at the Special Meeting which are not properly revoked will be voted at the Special Meeting in accordance with the instructions indicated on such proxies. If no instructions are indicated, such proxies will be voted FOR the amendment to the Certificate of Incorporation of the Company to authorize issuance of preferred stock of the Company.

Do stockholders have rights of appraisal in regards to the proposal?

     Under applicable Delaware law, the Company’s stockholders are not entitled to appraisal rights with respect to the proposal to approve a Certificate of Amendment to the Company’s Certificate of Incorporation to authorize the issuance of preferred stock.

What is the recommendation of the Company’s Board of Directors?

     The Company’s Board of Directors recommends that each stockholder vote FOR the Certificate of Amendment to the Certificate of Incorporation.


What will the consequences be if Proposal One is not approved?

     If Proposal One is not approved, the Company would have a distinct disadvantage against competitors in the current environment and will be limited in its ability to raise and attract capital to sustain the anticipated growth of the Company in the future.

Who pays for the solicitation of proxies?

     The accompanying proxy is being solicited by the Company’s Board of Directors. The Company will bear the entire cost of preparing, assembling, printing, mailing and distributing these proxy materials. In addition to solicitation by mail, proxies may be solicited in person or by telephone or by other means by the Company’s directors, officers, or employees, none of which will receive additional compensation for the solicitation of proxies. The Company has engaged Broadridge Financial Solutions, Inc., for a fee to be determined, to assist in the distribution and tabulation of proxies. The Company will also reimburse brokerage firms and other nominees, custodians and fiduciaries for costs incurred by them in mailing proxy materials to the beneficial owners of common stock of the Company as of the record date.

Does the Company send multiple proxy statements to two or more security holders who share an address?

     The Company only sends one set of proxy materials to security holders who share the same address and name unless the Company has received contrary instructions. If each security holder desires to have their own copy, they may notify the Company of that fact either orally or in writing. Notifications can be directed to Enterprise Financial Services Corp, 150 N. Meramec, Clayton, Missouri 63105, Attn: Investor Relations or via telephone at (800) 396-8141. Similarly, security holders may also contact the Company if they receive multiple copies of proxy materials and would prefer to receive a single copy in the future.

The date of this Proxy Statement is [November 7], 2008.


PROPOSAL ONE:
CERTIFICATE OF AMENDMENT TO THE CERTIFICATE OF INCORPORATION

     Under the Company’s existing Certificate of Incorporation, the Company does not have the authority to issue preferred stock. If the stockholders approve Proposal One to amend the Certificate of Incorporation pursuant to a certificate of Amendment (the “Certificate of Amendment”), the Company will be authorized to issue up to 5,000,000 shares of preferred stock of the Company having no par value per share (the “Preferred Stock”). The Preferred Stock to be authorized would have such designations, preferences and relative, participating, optional or other special rights and qualifications, limitations or restrictions thereof as shall be expressed in the resolution or resolutions providing for the issuance of such Preferred Stock adopted by the Board of Directors from time to time. As such, the Preferred Stock would be available for issuance without further action by the Company’s common stockholders, except as may be required by applicable law or pursuant to the requirements of the exchange or quotation system upon which the Company’s securities are then trading or quoted.

     The Board of Directors believes that the authorization of the Preferred Stock is advisable and in the best interests of the Company and its stockholders for several reasons. The authorization of the Preferred Stock would permit the Board of Directors to issue such stock without stockholder approvals or delay and, thereby, provide the Company with maximum flexibility in participating in capital raising opportunities under the federal government’s Emergency Economic Stabilization Act of 2008, in structuring acquisitions, joint ventures, strategic alliances and capital-raising transactions and for other corporate purposes. The Preferred Stock would enable the Company to respond promptly to and take advantage of market conditions and other favorable opportunities without incurring the delay and expense associated with calling a special meeting of the stockholders of the Company to approve a contemplated issuance of Preferred Stock. The Board of Directors believes that this will also help to reduce costs because it will not have to seek additional stockholder approval to issue shares of the Preferred Stock unless it is required to obtain the approval of the stockholders of the Company for the transaction under the rules of any quotation board or stock exchange to which it is subject. The Company presently contemplates no particular transaction involving the issuance of the Preferred Stock other than consideration of the federal government’s limited purchase of preferred stock in financial institutions. However, the Board of Directors believes that the Preferred Stock may be a component in any future raising of capital for the benefit of the Company.

     The full text of the proposed Certificate of Amendment is attached to this proxy statement as Appendix A. If the Certificate of Amendment is approved, the Board of Directors would be authorized to issue the Preferred Stock in one or more series, from time to time, with full or limited voting powers, or without voting powers, and with all designations, preferences and relative, participating, optional or other special rights, and qualifications, limitations or restrictions upon the Preferred Stock, as may be provided in the resolution or resolutions adopted by the Board of Directors from time to time. The authority of the Board of Directors will include, but not be limited to, the determination or fixing of the following with respect to shares of any class or series of the Preferred Stock:

  • the number of shares of the Preferred Stock (up to the number of shares authorized) and designation of any series of the Preferred Stock;
     
  • the liquidation preference, if any, attributed to the shares of the Preferred Stock;
     
  • the dividend rate attributed to the shares of the Preferred Stock and whether dividends are to be cumulative;
     
  • whether shares of the Preferred Stock are to be redeemable, and, if so, whether redeemable for cash, property or rights;
     
  • the rights to which the holders of shares of the Preferred Stock shall be entitled, and the preferences, if any, over any other series;
     
  • whether shares of the Preferred Stock shall be subject to the operation of a purchase, retirement or sinking fund, and, if so, upon what conditions;


  • whether shares of the Preferred Stock will be convertible into or exchangeable for shares of any other class or of any other series of any class of capital stock and the terms and conditions of the conversion or exchange;
     
  • the voting powers, full or limited, if any, of shares of the Preferred Stock;
     
  • whether the issuance of any additional shares of the Preferred Stock, or of any shares of any other series, will be subject to restrictions as to issuance, or as to the powers, preferences or rights of any of these other series; and
     
  • any other preferences, privileges and powers and relative, participating, optional or other special rights and qualifications, limitations or restrictions related to the Preferred Stock.

     The actual effect of the issuance of any shares of the Preferred Stock upon the rights of holders of common stock of the Company cannot be stated until the Board of Directors determines the specific rights of any shares of the Preferred Stock. However, the effects might include, among other things, restricting dividends on the common stock of the Company, diluting the voting power of the common stock of the Company, reducing the market price of the common stock of the Company or impairing the liquidation rights of the common stock of the Company without further action by the common stockholders of the Company. Holders of the Company’s common stock will not have preemptive rights with respect to the Preferred Stock.

     Although the Company may consider issuing shares of the Preferred Stock in the future for purposes of raising additional capital or in connection with acquisition transactions, there are currently no binding agreements or commitments with respect to the issuance of the Preferred Stock.

THE COMPANY’S BOARD OF DIRECTORS HAS APPROVED AND RECOMMENDS A VOTE “FOR” THE
PROPOSED CERTIFICATE OF AMENDMENT TO THE CERTIFICATE OF INCORPORATION.

OF CERTIFICATE OF INCORPORATION

     ENTERPRISE FINANCIAL SERVICES CORP, a corporation organized and existing under and by virtue of the General Corporation Law of the State of Delaware, 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:

     Article FOUR of the Certificate of Incorporation of the Corporation 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 Thirty-five million (35,000,000) 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) Thirty million (30,000,000) 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;


     (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; provided, however, that in all elections of Directors of the corporation, each holder of shares of the Common Stock shall have the right to cast as many votes as shall equal (x) the number of shares held by him, her or it, and multiplied by (y) the number of Directors of the corporation to be elected, and he, she or it may cast all such votes for a single Director or may distribute them among the number of Directors to be elected, or any two (2) or more of them, as such shareholder may deem fit. 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.
