We hope you will attend the Special Meeting, but whether or not you expect to be personally present, please vote your shares by signing, dating and promptly returning the enclosed proxy card in the accompanying postage-paid envelope, by telephone using the toll-free telephone number printed on the proxy card, or by voting on the Internet using the instructions printed on the proxy card.

If you attend the Special Meeting, you will be able to vote in person if you wish to do so, even if you have previously returned your proxy card, voted by telephone or via the Internet.

PROXY STATEMENT

SPECIAL MEETING OF SHAREHOLDERS

August 24, 2009

This proxy statement is being furnished to our shareholders in connection with the solicitation of proxies by the board of directors for use at the special meeting of shareholders to be held on August 24, 2009, and at any adjournments or postponements thereof.

Your proxy will be voted in the manner you specify if you vote properly and timely by the Internet or telephone, or if you complete and return the enclosed proxy card. You may revoke your proxy by notifying our secretary in writing, by delivering a properly executed proxy of later date (either in writing, telephonically or via the Internet) with the secretary at or before the special meeting, or by voting in person at the meeting.

This proxy statement was mailed to each shareholder of record at the voting record date, on or about July     , 2009.

VOTING

Record Date

At the close of business on July 20, 2009, the record date for the special meeting, we had     shares of common stock, par value $1.00 per share, referred to herein as “common stock,” outstanding and entitled to vote at the special meeting. On each proposal presented for a vote at the special meeting, each shareholder is entitled to one vote per share of common stock held as of the record date. As of the record date, our directors and executive officers held     shares of common stock, or approximately     % of all outstanding shares of common stock, and we believe that all of these shares will be voted in favor of Proposal 1.

Quorum

A quorum for the purposes of all matters to be voted on shall consist of shareholders representing, in person or by proxy, a majority of our total voting power. Shares represented at the special meeting that are abstained from voting will be considered present for the purpose of determining a quorum at the special meeting. If less than a majority of the outstanding shares of common stock is represented at the special meeting, the shares so represented may adjourn the special meeting to another date, time or place.

Vote Required

In voting to approve the amendment to our charter to increase the number of authorized shares of common stock (Proposal 1), you may vote in favor of or against the proposal or you may abstain from voting. The vote required to approve Proposal 1 is governed by our charter and is the affirmative vote of the holders of a majority of the outstanding shares of common stock. If Proposal 1 is approved, the charter will be amended to increase the number of authorized common shares from 25 million to 50 million.

Abstentions and Broker Nonvotes

Under certain circumstances, banks and brokers are prohibited from exercising discretionary authority for beneficial owners who have not provided voting instructions to the bank or broker (a “broker nonvote”). In these cases, and in cases where the shareholder abstains from voting on a matter, those shares will be counted for the purpose of determining if a quorum is present, but will not be included as votes cast with respect to those matters. We expect that banks and brokers will be allowed to exercise discretionary authority for beneficial owners who have not provided voting instructions with respect to Proposal 1, but abstentions will have the effect of a vote

“AGAINST” the proposal. Our board of directors urges shareholders to promptly vote by completing, dating and signing the accompanying proxy card and to return it promptly in the enclosed postage-paid envelope, or, if you hold your stock in “street name” through a bank or broker, by contacting your bank or broker and following the voting instructions of your bank or broker. You may also vote by Internet or telephone as explained below.

Any other matter that may be properly submitted to shareholders will be determined by a majority of the votes actually cast at the special meeting, either by proxy or in person. Votes withheld and broker nonvotes will not be counted and will have no effect.

PROXIES

We are furnishing this proxy statement and the accompanying proxy card in connection with the solicitation by our board of directors of proxies from our shareholders for use at the special meeting.

In addition to this solicitation by mail, our directors, officers and other employees, without additional compensation, may solicit proxies in favor of the proposals if deemed necessary, by personal contact, letter, telephone or other means of communication. We have retained Georgeson, Inc. to assist in the solicitation of proxies for a fee of approximately $5,500, plus reimbursement for out-of-pocket expenses actually incurred. We will request that brokers, nominees and other custodians and fiduciaries forward proxy solicitation materials to the beneficial owners of the shares of common stock where appropriate, and we will reimburse them for their reasonable expenses incurred in connection with such transmittals. We will bear the costs of solicitation of proxies for the special meeting.

How You Can Vote

Whether you hold shares in your own name, in street name, or through the IBERIABANK Corporation Retirement Savings Plan, you may direct your vote without attending the special meeting. If you are a shareholder of record or hold shares through the IBERIABANK Corporation Retirement Savings Plan, you may vote by granting a proxy, as follows:

• By Internet or Telephone — You may submit your proxy by following the instructions on the proxy card. Shareholders of record who are also participants in the Retirement Savings Plan will receive two proxy cards. If you vote using the Internet or telephone, you do not need to return your proxy card (or cards, if you are both a record shareholder and a participant in the Retirement Savings Plan). We have designed telephone and Internet voting procedures that authenticate your identity as a shareholder, allow you to give your voting instructions and confirm that your instructions have been properly recorded. The deadline for telephone and Internet voting is 3:00 a.m., Eastern Time, on August 24, 2009.

• By Mail — You may vote by mail by signing and dating your proxy card (or cards, if you are both a record shareholder and a participant in the Retirement Savings Plan) and mailing it in the envelope provided. You should sign your name exactly as it appears on the proxy card. If you are signing in a representative capacity (for example as guardian, executor, trustee, custodian, attorney or officer of a corporation), you should indicate your name and title or capacity.

2

For shares held in street name, you should follow the voting directions that your broker or nominee provides. You can complete and mail a voting instruction card to your broker or nominee or, in most cases, submit voting instructions by telephone or the Internet. If you provide specific voting instructions, your broker or nominee will vote your shares as you direct.

If you choose to vote at the special meeting, and:

• you are a registered shareholder of record or hold shares in the Retirement Savings Plan, you should bring the enclosed proxy card and proof of identity; or

• you hold your shares in street name, you must obtain and bring a broker representation letter in your name from your bank, broker or other holder of record and proof of identity.

At the appropriate time during the special meeting, we will ask the shareholders present whether anyone wishes to vote in person. You should raise your hand to receive a ballot to record your vote.

Even if you plan to attend the special meeting, we encourage you to vote in advance of the special meeting by telephone, Internet or mail so your vote will be counted if you later decide not to attend the meeting.

All proxies properly voted by telephone or the Internet and all properly executed written proxy cards that are delivered to us (and not later revoked) will be voted at the special meeting in accordance with the directions given. In voting with regard to Proposal 1, you may vote for or against the proposal or abstain from voting. You should specify your choices on the proxy card. IF NO SPECIFIC INSTRUCTIONS ARE GIVEN WITH REGARD TO THE MATTERS TO BE VOTED UPON, THE SHARES REPRESENTED BY A SIGNED PROXY CARD WILL BE VOTED “FOR” PROPOSAL 1 LISTED ON THE PROXY CARD.

The form of proxy confers discretionary authority on the persons named therein with respect to matters incident to the conduct of the special meeting and with respect to any other matter presented to the special meeting if notice of such matter has not been delivered to us in accordance with our Articles of Incorporation. Except for procedural matters incident to the conduct of the special meeting, we do not know of any other mater that may come before the special meeting. If any other matter is properly brought before the special meeting as to which proxies in the accompanying form confer discretionary authority, the persons named in the accompanying proxy will vote the shares represented by such proxies as determined by a majority of the board of directors.

PROPOSAL 1

APPROVAL OF AMENDMENT TO THE ARTICLES OF INCORPORATION

TO INCREASE THE NUMBER OF AUTHORIZED SHARES OF COMMON STOCK

On December 16, 2008, we completed a follow-on public offering of 2,875,000 shares of common stock. Net proceeds from the offering were approximately $109 million. On July 7, 2009, we completed a second follow-on public offering of 4,427,500 shares of common stock. Net proceeds of the second offering were approximately $164.5 million. Consummation of these offerings has strengthened our consolidated capital position and is expected to enable us to capitalize on recruiting and acquisition opportunities.

The Articles of Incorporation currently authorize the issuance of up to 25 million shares of common stock. As of August 1, 2009, a total of     shares of common stock were issued and outstanding or reserved for issuance, as described below:

•     shares were issued and outstanding;

•     shares were held in treasury; and

•     shares were subject to stock options and warrants granted under stock incentive plans.

As a result, as of August 1, 2009,     shares of common stock were unreserved and available for future issuance.

Our board of directors considered the limited number of available common shares and voted to adopt, subject to the approval of a majority of the outstanding shares of common stock, an amendment to the Articles of Incorporation increasing the authorized shares of common stock from 25 million shares to 50 million shares. Our board of directors unanimously recommends that shareholders vote “For” approval of the increase in our authorized common shares.

The board of directors believes that it is advisable to have a greater number of authorized shares of common stock available for issuance in connection with acquisitions and mergers, public or private financings, and various general corporate programs and purposes.

We may from time to time consider acquisitions, including FDIC – assisted transactions, and mergers as opportunities arise, stock splits and public or private financings to provide us with capital, any or all of which may involve the issuance of additional shares of common stock or securities convertible into shares of common stock. It is widely expected that federal programs adopted in response to the current financial crisis and continuing bank failures will accelerate consolidation of the financial institution industry. By having additional common shares authorized, we can be prepared to act quickly as opportunities arise. Also, additional shares of common stock may be necessary to meet anticipated future obligations of our stock-based compensation and employee benefit plans, under which we may grant future equity awards to our officers, other employees and directors. We believe that these benefit plans are critical to retaining our current management team and attracting additional management talent during this turbulent and uncertain period. The board of directors believes that having the authority to issue additional shares of common stock will avoid the possible delays and significant expense of calling and holding an additional special meeting of shareholders to increase the authorized common shares at a later date and will enhance its ability to respond promptly to opportunities for acquisitions, mergers, stock splits and additional financings. Such a delay may result in our inability to consummate a desired transaction under a required deadline.

If Proposal 1 is approved, the additional authorized shares of common stock may be issued for such consideration, cash or otherwise, at such times and in such amounts as the board of directors may determine without further shareholder approval, except to the extent that shareholder approval is required by applicable laws, rules or regulations. Because our common stock is traded on the Nasdaq Global Select Market, shareholder approval must be obtained, under applicable Nasdaq rules, prior to the issuance of shares for certain purposes, including the issuance of greater than 20% of the then outstanding shares of common stock in connection with a private financing or an acquisition or merger.

4

As of the date of this proxy statement and except as described above, the company has no understandings, agreements or commitments to issue common stock or to reserve additional common shares for issuance under equity compensation plans. The company and its executive officers and directors have agreed that for a period of 90 days from July 1, 2009, they will not, without the prior written consent of the representatives on behalf of the underwriters of our most recent public offering, subject to certain exceptions, sell, offer to sell or otherwise dispose of or hedge any shares of common stock or any securities convertible into or exercisable or exchangeable for common stock. The representatives in their sole discretion may release the securities subject to these lock-up agreements at any time without notice.

The authorization of additional shares of common stock will not, by itself, have any effect on the rights of present shareholders. The additional 25 million shares to be authorized will be a part of the existing class of common stock and, if and when issued, would have the same rights and privileges as the shares of common stock presently issued and outstanding. Shareholders do not have preemptive rights to subscribe for or purchase additional shares of common stock. Accordingly, the issuance of additional shares of common stock for corporate purposes other than a stock split or stock dividend could have a dilutive effect on the ownership and voting rights of shareholders at the time of issuance.

The increase in authorized common shares is not being proposed as a means of preventing or dissuading a change in control or takeover of our company. However, use of these shares for such a purpose is possible. Authorized but unissued or unreserved common stock and preferred stock, for example, could be issued in an effort to dilute the ownership and voting power of persons seeking to obtain control or could be issued to purchasers who would support the board in opposing a takeover proposal. In addition, the increase in authorized common stock, if approved, may have the effect of discouraging a challenge for control or make it less likely that such a challenge, if attempted, would be successful. Our board of directors and executive officers have no knowledge of any current effort to obtain control of the company or to accumulate large amounts of common shares.

The full text of the proposed amendment to our Articles of Incorporation is attached as Appendix A to this proxy statement.

If Proposal 1 is approved, the number of authorized shares of common stock will be increased and the board of directors will have the right to issue, without further shareholder approval, an additional 25 million shares of common stock. If approved, Proposal 1 will be effective upon the filing of the charter amendment with the Secretary of State of the State of Louisiana promptly after the special meeting.

Approval of the amendment by the shareholders will not require that the amendment to the Articles of Incorporation be filed, and our board of directors may decide to abandon the amendment after shareholder approval if they determine that it is in the best interest of the company to do so. Shareholders have no dissenters’ rights or rights of appraisal with respect to the vote to approve this amendment.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE “FOR” APPROVAL OF THE AMENDMENT TO THE ARTICLES OF INCORPORATION TO INCREASE THE NUMBER OF AUTHORIZED SHARES OF COMMON STOCK.

STOCK OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following tables include, as of the record date, certain information as to the common stock beneficially owned by:
