NOTICE OF ANNUAL MEETING

OF SHAREHOLDERS

To Our Shareholders:

The annual meeting of the shareholders of Atmos Energy Corporation will be held in the Pavilion Ballroom at the Belo Mansion, 2101 Ross Avenue, Dallas, Texas 75201 on Wednesday, February 4, 2009, at 11:00 a.m. Central Standard Time for the following purposes:

Shareholders of record of our common stock at the close of business on December 10, 2008 will be entitled to notice of, and to vote at, such meeting. The stock transfer books will not be closed. Your vote is very important to us. Regardless of the number of shares you own, please vote. All shareholders of record can vote (i) over the Internet, (ii) by toll-free telephone (please see the proxy card for instructions), (iii) by written proxy by signing and dating the proxy card and returning it or (iv) by attending the annual meeting in person. These various options for voting are described in the Notice of Internet Availability of Proxy Materials or proxy card.

For all shareholders who participate in our Retirement Savings Plan and Trust (“RSP”), your vote over the Internet, by telephone or on your proxy card will serve as voting instructions to the trustee of the RSP. If you have shares of our common stock issued to you under the RSP, only the trustee can vote your plan shares even if you attend the annual meeting in person.

All shareholders who hold their shares in street name (in the name of a broker, bank or other nominee) may submit a written vote through voting instruction forms provided by their brokers, banks or other nominees. Such shareholders who hold their shares in street name can also generally vote their proxies over the Internet or by telephone, in accordance with voting instructions provided by their brokers, banks or other nominees. Under rules of the New York Stock Exchange (“NYSE”), brokers, banks or other nominees will have the discretion to vote the shares of customers who fail to provide voting instructions for the proposals described above, other than the shareholder proposal. Therefore, if you do not provide instructions to your broker, bank or other nominee to vote your shares, they may vote your shares on such proposals being presented at our annual meeting, other than the shareholder proposal. If you own your shares in street name and you want to vote in person at the meeting, you must first obtain a legal proxy from your street name nominee and bring that legal proxy to the annual meeting.

We encourage you to receive all proxy materials in the future electronically to help us save printing costs and postage fees, as well as natural resources in producing and distributing these materials. If you wish to receive these materials electronically next year, please follow the instructions on the proxy card.

PROXY STATEMENT

for the

2009 ANNUAL MEETING OF SHAREHOLDERS

to be Held on February 4, 2009

GENERAL

Date, Time, Place and Purpose of Meeting

Our 2009 annual meeting of shareholders will be held on Wednesday, February 4, 2009, at 11:00 a.m., Central Standard Time in the Pavilion Ballroom at the Belo Mansion, 2101 Ross Avenue, Dallas, Texas 75201. The purpose of the 2009 annual meeting is set forth in the Notice of Annual Meeting of Shareholders to which this proxy statement is attached. Atmos Energy Corporation is referred to as the “Company,” “we,” “our” or “us” in this proxy statement.

Internet Availability of Proxy Materials

Under rules of the Securities and Exchange Commission (“SEC”), we are furnishing proxy materials to our shareholders primarily over the Internet, rather than mailing paper copies of the materials (including our Summary Annual Report and Annual Report on Form 10-K for fiscal 2008) to each shareholder. If you received only a Notice of Internet Availability of Proxy Materials (the “Notice”) by mail or electronic mail, you will not receive a paper copy of these proxy materials unless you request one. Instead, the Notice will instruct you as to how you may access and review the proxy materials on the Internet. The Notice will also instruct you as to how you may access your proxy card to vote over the Internet. If you received a Notice by mail or electronic mail and would like to receive a paper copy of our proxy materials, free of charge, please follow the instructions included in the Notice.

We anticipate that the Notice will be mailed to our shareholders on December 22, 2008 and will be sent by electronic mail to our shareholders who have opted for such means of delivery on December 26, 2008.

Revocability and Voting of Proxies

Any shareholder of record giving a proxy has the power to revoke the proxy at any time prior to its exercise by (1) submitting a new proxy with a later date, including a proxy given over the Internet or by telephone; (2) notifying our Corporate Secretary in writing before the meeting or (3) voting in person at the meeting. Any shareholders owning shares in street name who wish to revoke voting instructions previously given to their broker, bank or other nominee should contact such broker, bank or other nominee for further instructions. An independent inspector will count the votes. Your vote will not be disclosed to us and will remain confidential except under special circumstances. For example, a copy of your proxy card will be sent to us if you add any written comments to the card. If you are a shareholder of record and give us your signed proxy, but do not specify how to vote, we will vote your shares in favor of the nominees for election of directors (see “Proposal One—Election of Directors” beginning on page 5), in favor of the proposal to ratify the Audit Committee’s appointment of Ernst & Young LLP as the independent registered public accounting firm for the Company for fiscal 2009 (see “Proposal Two—Ratification of Appointment of Independent Registered Public Accounting Firm” beginning on page 44) and against the shareholder proposal (see “Proposal Three—Shareholder Proposal Regarding Declassification of Board of Directors” beginning on page 45).

Solicitation of Proxies

The proxy accompanying this statement is solicited by the management of the Company at the direction of our Board of Directors. These materials were first sent to our shareholders on December 22, 2008. We expect to solicit proxies primarily by mail, but our directors, officers, employees and agents may also solicit proxies in person or by telephone or other electronic means. We will pay for all costs of preparing, assembling and distributing the proxies and accompanying materials for the annual meeting of shareholders, including the costs of reimbursing brokers and nominees for forwarding proxies and proxy materials to their principals. We will ask brokers, banks or other nominees to prepare and send a Notice to customers or clients for whom they hold shares and forward copies of the proxy materials to such beneficial owners who request a paper copy. In addition, Morrow & Co., LLC (“Morrow”) will assist us in the solicitation of proxies. We will pay approximately $6,500 in fees, plus expenses and disbursements, to Morrow for its proxy solicitation services.

Common Stock Information; Record Date

As of December 10, 2008, our record date, there were 91,556,911 shares of our common stock, no par value, issued and outstanding, all of which are entitled to vote. These shares constitute the only class of our stock issued and outstanding. As stated in the Notice of Annual Meeting of Shareholders, only shareholders of record at the close of business on December 10, 2008 will be entitled to vote at the meeting. Each share is entitled to one vote.

Quorum Requirement

Our bylaws provide that if the holders of a majority of the issued and outstanding shares of our common stock entitled to vote are present in person or represented by proxy, there will be a quorum. The aggregate number of votes entitled to be cast by all shareholders present in person or represented by proxy at the annual meeting, whether those shareholders vote for, against or abstain from voting on any matter, will be counted for purposes of determining whether a quorum exists. Broker non-votes, which are described below, will also be considered present for purposes of determining whether a quorum exists.

Broker Non-Votes and Vote Required

If a broker, bank or other nominee (“broker”) holds your shares and you have previously elected to receive a paper copy of your proxy materials, this proxy statement and a proxy card have been sent to your broker. You may have received this proxy statement directly from your broker, together with instructions as to how to direct the broker to vote your shares. If you desire to have your vote counted, it is important that you return your voting instructions to your broker. Rules of the NYSE determine whether proposals presented at shareholder meetings are “routine” or “non-routine.” If a proposal is routine, a broker holding shares for an owner in street name may vote on the proposal without voting instructions from the owner. If a proposal is non-routine, the broker may vote on the proposal only if the owner has provided voting instructions. A “broker non-vote” occurs when the broker is unable to vote on a proposal because the proposal is non-routine and the owner does not provide instructions. Proposal One—the proposal to elect directors and Proposal Two—the proposal to ratify the appointment of Ernst & Young LLP as the independent registered public accounting firm for the Company for fiscal 2009 are considered routine proposals under the rules of the NYSE. As a result, brokers holding shares for an owner in street name may vote on both Proposals One and Two, even if

2

Table of Contents

no voting instructions are provided by the owner of the shares. However, Proposal Three—the shareholder proposal regarding the declassification of our Board of Directors, is not considered a routine proposal. Therefore, brokers may vote on this proposal only if voting instructions are provided by the owner of the shares.

For each of the proposals presented in this proxy statement, the number of votes required for approval is a majority of the shares of our common stock present or represented by proxy and entitled to vote at the meeting. If any other proposals are properly presented to the shareholders at the meeting, the number of votes required for approval will depend on the nature of the proposal. Generally, under Texas and Virginia law and our bylaws, the number of votes required to approve a proposal is a majority of the shares of common stock present or represented by proxy and entitled to vote at the meeting. The proxy gives discretionary authority to the proxy holders to vote on any matter not included in this proxy statement that is properly presented to the shareholders at the meeting. The persons named as proxies on the proxy card are Robert W. Best, Chairman and Chief Executive Officer, Charles K. Vaughan, Director and Presiding Director and Dan Busbee, Director and Chairman of the Audit Committee.

Security Ownership of Certain Beneficial Owners

The following table lists the beneficial ownership, as of December 1, 2008, with respect to each person known by us to be the beneficial owner of more than five percent of any class of our voting securities.

Security Ownership of Management and Directors

The following table lists the beneficial ownership, as of December 1, 2008, of our common stock, the only class of securities issued and outstanding, with respect to all our directors and nominees for director, our executive officers named in the Summary Compensation Table on page 31 of this proxy statement and all our directors and executive officers as a group. Except as otherwise noted, the directors, nominees and named executive officers, individually or as a group, have sole voting and investment power with respect to the shares listed.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires our directors and executive officers and persons who beneficially own more than ten percent of our common stock to file with the SEC and the NYSE initial reports of ownership and reports of changes in their ownership in our common stock. Directors, executive officers and greater-than-ten-percent beneficial shareholders are required by SEC regulations to furnish us with copies of all Section 16(a) forms they file. Based solely on a review of the copies of such reports furnished to us, we believe that, during fiscal 2008, all of our directors, executive officers and greater-than-ten-percent beneficial owners were in compliance with the Section 16(a) filing requirements, except for Mr. Best, who did not timely report on Form 4, a purchase of 1,887 shares for the account of his son in the Company’s Direct Stock Purchase Plan.

PROPOSAL ONE—ELECTION OF DIRECTORS

Background

Pursuant to our bylaws, the Board is divided into three classes, each of which class consists, as nearly as possible, of one-third of the total number of directors constituting the entire Board. In accordance with our bylaws, Ruben E. Esquivel who was elected to the Board effective September 1, 2008, is required to be elected by our shareholders at the immediately succeeding annual meeting of shareholders. Accordingly, Mr. Esquivel has been nominated to continue serving as a Class I director for a three-year term expiring in 2011. In addition, directors for Class II are to be elected at the 2009 annual meeting of shareholders for three-year terms expiring in 2012. Richard W. Cardin, Thomas C. Meredith, Nancy K. Quinn, Stephen R. Springer and Richard Ware have been nominated to serve as Class II directors. All nominees were recommended for nomination by the Nominating and Corporate Governance Committee of the Board. We did not pay a fee to any third party to identify, evaluate or assist in identifying or evaluating potential nominees for the Board. The Nominating and Corporate Governance Committee did not receive any recommendations from a shareholder or a group of shareholders who, individually or in the aggregate, beneficially owned greater than five percent of our common stock for at least one year. Ms. Quinn and Messrs. Cardin, Springer, Ware and Dr. Meredith were last elected to three-year terms by the shareholders at the 2006 annual meeting of shareholders in February 2006. The Board is nominating Ms. Quinn and Messrs. Cardin, Springer, Ware and Dr. Meredith to continue serving as Class II directors, whose three-year terms will expire in 2012.

The other directors listed below under “Directors Continuing in Office” will continue to serve in their positions for the remainder of their current terms, except for Mr. Busbee who will be retiring from the Board immediately following the annual meeting, in accordance with the Company’s bylaws. The names, ages and biographical summaries of (i) the persons who have been nominated to serve as our directors and (ii) the directors who are continuing in office until the expiration of their terms and the class in which such nominee or other director has been designated, are set forth under “Nominees for Director” beginning on page 6 and “Directors Continuing in Office” beginning on page 8. Each of the nominees has consented to be a nominee and to serve as a director if elected and all votes authorized by the proxy will be cast FOR all of the nominees. If we receive proxies that are signed but do not specify how to vote, we will vote your shares FOR all of the nominees. If we receive proxies that contain a vote to “withhold authority” for the election of one or more director nominees, such vote will not be counted in determining the number of votes cast for those nominees but will be counted for quorum purposes. In order to be elected as a director, our bylaws require a nominee to receive the vote of a majority of all outstanding shares of our common stock entitled to vote and represented in person or by proxy at a meeting of shareholders at which a quorum is present.

Table of Contents

According to our bylaws, any shareholder may make nominations for the election of directors if notice of such nominations is delivered to, or mailed and received by the Corporate Secretary of the Company at our principal executive offices, not less than 60 days nor more than 85 days prior to the date of the originally scheduled meeting. However, if less than 75 days’ notice or prior public disclosure of the date of the meeting is given by the Company, notice of such nomination must be so received not later than the close of business on the 25th day following the earlier of the day on which notice of the meeting was sent or the day on which such public disclosure was made. Since we are providing less than 75 days’ notice or prior public disclosure of the date of the 2009 annual meeting, shareholders may make nominations for the election of directors at the 2009 annual meeting, if notice of such nominations is delivered to, or mailed and received by the Corporate Secretary of the Company at our principal executive offices no later than the close of business on January 16, 2009, the 25th day following the day on which notice of the meeting was sent, December 22, 2008. If nominations are not so made, only the nominations made by the Board of Directors may be voted upon at the 2009 annual meeting.

Cardin, Retired, formerly with Arthur Andersen LLP from 1958 to 1994 where he served as office managing partner in the Chattanooga and Nashville, Tennessee offices from 1969 to 1994; and currently a director of United States Lime and Minerals, Inc.

CORPORATE GOVERNANCE AND OTHER BOARD MATTERS

Corporate Governance

In accordance with and pursuant to the corporate governance-related listing standards of the NYSE, the Board has adopted and periodically updated our Corporate Governance Guidelines, which govern the structure and proceedings of the Board and contain the Board’s position on many governance issues. The Board has also adopted and periodically updated the Code of Conduct for our directors, officers and employees. The Code of Conduct provides guidance to the Board and management in areas of ethical business conduct and risk and provides guidance to employees and directors by helping them to recognize and deal with ethical issues including, but not limited to (i) conflicts of interest, (ii) gifts and entertainment, (iii) confidential information, (iv) fair dealing, (v) protection of corporate assets and (vi) compliance with rules and regulations. We have provided to our employees a toll-free compliance hotline and a Web site by which they may report on an anonymous basis any observation of unethical behavior. In addition, the Board has adopted and periodically updated the charters for each of its Audit, Human Resources and Nominating and Corporate Governance Committees. All of the foregoing documents are posted on the Corporate Governance page of our Web site at www.atmosenergy.com. Such documents are also available in print free of charge to any shareholder upon request to our Corporate Secretary at our principal executive offices.

Independence of Directors

The Board is comprised of a majority of independent directors in accordance with NYSE corporate governance-related listing standards. The Board made its determination of the independence of each of its members based on the Categorical Standards of Director Independence (“Standards”) it has adopted, which are consistent with the NYSE listing standards. In accordance with the Standards and the Company’s Corporate Governance Guidelines, in order to be considered independent, a director must not have a direct or indirect material relationship with the Company or its management, other than as a director. The Standards specify the criteria by which the independence of our directors will be determined, including guidelines for directors and their immediate families with respect to past employment or affiliation with the Company, our management or our independent registered public accounting firm. For purposes of the Standards, the Board has adopted the definition of an “immediate family member” as set forth by the NYSE, which includes a director’s spouse, parents, children, siblings and in-laws of the director, as well as anyone else (other than domestic employees) who shares such director’s home. The Standards and our Corporate Governance Guidelines are posted on the Corporate Governance page of our Web site. Such documents are also available in print free of charge to any shareholder upon request to our Corporate Secretary at our principal executive offices.

Based on its review of the Standards, as well as the NYSE listing standards, and taking into consideration all business relationships between the Company and each director other than Mr. Springer, the Board has concluded that none of such relationships are material. Accordingly, the Board has determined that all non-employee members of the Board, other than Mr. Springer, are independent members of the Board. However, because Mr. Springer’s son-in-law is a partner with the firm of Ernst & Young LLP, our independent registered public accounting firm, under the Standards and the corporate governance-related listing standards of the NYSE, Mr. Springer may not be considered independent from the Company. Mr. Springer’s son-in-law is not involved in our audit and is not considered a “covered person” with respect to us, as defined under the SEC’s independence-related regulations for auditors. Thus, this relationship has no effect on Ernst & Young LLP’s

10

Table of Contents

independence as our independent registered public accounting firm. In addition, Mr. Springer does not serve on our Audit, Nominating and Corporate Governance or Human Resources Committees.

Related Person Transactions

In accordance with applicable SEC rules and in recognition that transactions into which we enter with related persons can present potential or actual conflicts of interest, our Board has adopted written guidelines with respect to related person transactions. For purposes of these guidelines, a reportable “related person transaction” is a transaction between the Company and any related person (i) involving more than $120,000 when aggregated with all similar transactions during any fiscal year and (ii) such “related person” has or will have a direct or indirect material interest in such transaction (other than solely as a result of being a director or a less than 10 percent beneficial owner of another entity). A “related person” is any (a) person who is or was (since the beginning of the last fiscal year) an executive officer, director or nominee for election as a director of the Company; (b) person who beneficially owns more than five percent of the Company’s common stock or (c) immediate family member of any of the foregoing. An immediate family member includes a person’s spouse, parents, stepparents, children, stepchildren, siblings, in-laws and anyone residing in such person’s home (other than a tenant or employee).

Under the guidelines, all executive officers, directors and director nominees are required to identify, to the best of their knowledge after reasonable inquiry, business and financial affiliations involving themselves or their immediate family members that could reasonably be expected to give rise to a reportable related person transaction. Executive officers, directors and director nominees are required to advise the Corporate Secretary of the Company promptly of any change in the information provided and are asked periodically to review and reaffirm this information.

The Nominating and Corporate Governance Committee reviews reports developed under the guidelines and makes a recommendation to the Board as to whether the committee determines that an identified transaction is required to be reported as a related person transaction under SEC rules. In determining materiality for this purpose, information is considered material if, in light of all the circumstances, there is a substantial likelihood a reasonable investor would consider the information important in deciding whether to buy, sell or vote shares of Company stock. Transactions within the categorical standards specified below, which are pre-approved by the committee, will be presumed not to be material and therefore, not reportable. Other transactions are assessed for materiality based on the specific facts and circumstances of the transaction. An individual director is required to abstain from the decision regarding transactions involving that director or his or her family members.

Under SEC rules, certain transactions are deemed not to involve a material interest (including transactions in which the amount involved in any 12-month period is less than $120,000 and transactions with entities where a related person’s interest is limited to service as a non-employee director). In addition, the committee will presume that the following transactions do not involve a material interest for purposes of reporting under applicable SEC rules:

11

Table of Contents

The committee has reviewed the Company’s ordinary course of business transactions during fiscal 2008 with companies for which non-employee directors serve as executive officers and all other related person transactions and determined that, in accordance with the categorical standards described above, none of those transactions involved a material interest and thus are not reportable. In addition, the Company is not aware of any related person transactions required to be reported under applicable SEC rules since the beginning of the last fiscal year where our policies and procedures did not require review, or where such policies and procedures were not followed.

Qualifications for Directors

The Nominating and Corporate Governance Committee utilizes a variety of methods for identifying nominees for director, including considering potential director candidates who come to the committee’s attention through current officers, directors, professional search firms, shareholders or other persons. Nominees for director should possess the level of education, experience, sophistication and expertise required to perform the duties of a member of the board of directors of a public company of our size and scope. Once a person is nominated, the committee will assess the qualifications of the nominee, including an evaluation of the nominee’s judgment and skills. The Company’s Corporate Governance Guidelines provide that nominees for director will be selected on the basis of outstanding achievement in their personal careers; prior board experience; wisdom; integrity; ability to make independent, analytical inquiries; understanding of the business environment; and willingness to devote adequate time to Board duties. Each nominee for director should also have a basic understanding of (i) the principal operational and financial objectives and plans and strategies of the Company, (ii) the results of operations and financial condition of the Company and of any significant subsidiaries or business segments and (iii) the relative standing of the Company and its business segments in relation to its competitors. The Board is committed to diversified membership and will not discriminate on the basis of race, color, national origin, gender, religion, disability or other personal characteristics in selecting nominees.

Procedures for Nomination or Recommending for Nomination Candidates for Director

The Nominating and Corporate Governance Committee also considers sound and meritorious nomination suggestions for directors from shareholders. Any shareholder may submit a nomination for director by following the procedures outlined in our bylaws and described under “Proposal One–Election of Directors” beginning on page 5. There are no differences in the manner in which the

12

Table of Contents

committee evaluates nominees for director based on whether or not the nominee is recommended by a shareholder. All director candidates shall, at a minimum, possess the qualifications for director discussed above. All letters of recommendation for nomination at the 2009 annual meeting should be sent to our Corporate Secretary at our principal executive offices and must be received no later than January 16, 2009. Such letters should include the following: (i) name, address and number of shares owned by the nominating shareholder, (ii) the nominee’s name and address, (iii) a listing of the nominee’s background and qualifications, (iv) a description of all arrangements between such shareholder and each nominee and any other person and (v) all other information relating to such person that is required to be disclosed in the solicitations for proxies for election of directors under applicable SEC and NYSE rules. A signed statement from the nominee should accompany the letter of recommendation indicating that he or she consents to being considered as a nominee and that, if nominated by the Board and elected by the shareholders, he or she will serve as a director.

Presiding Director and Communications with Directors

In accordance with the corporate governance-related listing standards of the NYSE, the Board has designated Charles K. Vaughan as the presiding director at all meetings of non-management directors during fiscal 2009, which meetings will continue to be held by the Board on a regular basis. In addition, all independent members of the Board meet as a group at least once annually. Shareholders and other interested parties may communicate with Mr. Vaughan, individual non-management directors, or the non-management directors as a group, by writing to Board of Directors, Atmos Energy Corporation, P.O. Box 650205, Dallas, Texas, 75265-0205 or by email at boardofdirectors@atmosenergy.com.

The Work Session/Annual Meeting Committee consists of Messrs. Bain, Douglas, Garland, Nichol, Springer and Ware. Mr. Bain serves as chairman of the committee. This committee selects the site and plans the meeting and agenda for the special meeting of the Board held each year for the purpose of focusing on long-range planning and corporate strategy issues and selects the site for the annual meeting of shareholders. During the last fiscal year, the Work Session/Annual Meeting Committee held two meetings.

Other Board and Board Committee Matters

Human Resources Committee Interlocks and Insider Participation.    As discussed above, the members of the Human Resources Committee during the last fiscal year were Messrs. Bain, Busbee, Douglas, Esquivel, Garland, Gordon and Nichol. None of such persons were, during fiscal 2008, or previously, an officer or employee of the Company or any of our subsidiaries. In addition, there were no interlocking relationships between any executive officer of the Company and any other corporation during fiscal 2008.

Attendance at Board Meetings.    During fiscal 2008, our Board held 12 meetings and each director attended at least 75 percent of the aggregate of (a) all meetings of the Board and (b) all meetings of the committees of the Board on which such director served. In addition, all members of

14

our Board, other than Mr. Esquivel who joined the Board on September 1, 2008, attended the 2008 annual meeting of shareholders in Fort Worth, Texas on February  6, 2008. We strongly support and encourage each member of our Board to attend our annual meeting of shareholders.

DIRECTOR COMPENSATION

Annual Compensation.    As compensation for serving as a director during fiscal 2008, each of our non-employee directors received an annual retainer of $37,500, payable on a quarterly basis. Beginning October 1, 2008, each of our non-employee directors will receive an annual retainer of $45,000. Since June 1, 2007, our presiding director, Mr. Vaughan, has received an annual fee of $25,000 for additional services he performs in connection with those duties. All annual fees and retainers paid to Board members who have served less than a full year are pro-rated on a daily basis. Each non-employee director receives a fee of $1,500 per meeting for attendance at each meeting of the Board or Board committee as well as any other Company-related business meeting, excluding telephone conference meetings. The fee paid to non-employee directors for participation in any telephonic conference meeting is one-half of the regular meeting fee. Committee chairpersons are also paid an additional annual fee of $5,000 for additional services performed in connection with their committee duties and responsibilities. All directors are reimbursed for reasonable expenses incurred in connection with attendance at Board and committee meetings. A director who is also an officer or employee receives no compensation for his or her service as a director. We provide business travel accident insurance for non-employee directors and their spouses. The policy provides $100,000 coverage to directors and $50,000 coverage to their spouses per accident while traveling on Company business.

The following table sets forth all compensation paid to our non-employee directors for fiscal 2008.

AUDIT COMMITTEE-RELATED MATTERS

Independence of Audit Committee Members, Financial Literacy and Audit Committee Financial Experts

In addition to being declared as independent under the NYSE listing standards, applicable NYSE and SEC rules and regulations require that each member of an audit committee satisfy additional independence and financial literacy requirements, and at least one of these members must satisfy the additional requirement of having accounting or related financial management expertise. This additional requirement can be satisfied if the Board determines that at least one Audit Committee member is an “audit committee financial expert” within the meaning of applicable SEC rules and regulations.

17

Table of Contents

Generally, the additional independence requirements provide that (i) a member of the Audit Committee, or his or her immediate family members, are prohibited from receiving any direct or indirect compensation or fee from the Company or its affiliates and (ii) he or she may not be an affiliated person of the Company or any of its subsidiaries. An “immediate family member” is defined by applicable NYSE rules to include a director’s spouse, parents, children, siblings and in-laws of the director, as well as anyone else (other than domestic employees) who shares such director’s home.

Generally, the financial literacy requirements provide that the Board, in its business judgment, shall determine if each member is financially literate, taking into account factors such as the member’s education, experience and ability to read and understand financial statements of public companies. Also, audit committee financial experts must have the following five additional attributes: (i) an understanding of generally accepted accounting principles and financial statements, (ii) the ability to assess the general application of such principles in connection with the accounting for estimates, accruals and reserves, (iii) experience preparing, auditing, analyzing or evaluating financial statements that present a breadth and level of complexity of accounting issues that are generally comparable to the breadth and complexity of issues that can reasonably be expected to be raised by the Company’s financial statements, or experience actively supervising one or more persons engaged in such activities, (iv) an understanding of internal control over financial reporting and (v) an understanding of how an audit committee functions.

Based on its review of the independence, financial literacy and financial expert requirements discussed above as well as its review of their individual backgrounds and qualifications, the Board has determined that all members of the Audit Committee satisfy the additional independence and financial literacy requirements imposed by the SEC and NYSE for members of an audit committee. The Board has also designated Ms. Quinn, and Messrs. Busbee and Cardin, each as an “audit committee financial expert,” as such term is defined by applicable rules and regulations of the SEC. As provided by the safe harbor contained in applicable SEC rules and regulations, our audit committee financial experts will not be deemed “experts” for any purpose as a result of being so designated. In addition, such designation does not impose on such persons any duties, obligations or liabilities that are greater than the duties, obligations and liabilities imposed on such persons as members of the Audit Committee or the Board in the absence of such designation. Such designation also does not affect the duties, obligations or liabilities of any other member of the Audit Committee or the Board.

Audit Committee Report

The Audit Committee of the Board of Directors is composed of six directors who are independent directors as required by and in compliance with all applicable listing standards of the NYSE as well as all applicable rules and regulations of the SEC. The Audit Committee acts under a written charter adopted by the Board of Directors, which sets forth its detailed responsibilities and duties, as well as requirements for the Audit Committee’s composition and meetings. A copy of the charter is available on the Corporate Governance page of the Company’s Web site at www.atmosenergy.com.

The primary purpose of the Audit Committee is to oversee the Company’s financial reporting process on behalf of the Board of Directors. Management has the primary responsibility for the financial statements and the financial reporting process, including systems of internal control over financial reporting and disclosure controls and procedures. Ernst & Young LLP, our independent registered public accounting firm, is responsible for (i) expressing an opinion, based on its audit, as to the conformity of the audited financial statements with generally accepted accounting principles and

18

Table of Contents

(ii) expressing an opinion, based on its audit, on the effectiveness of the Company’s internal control over financial reporting.

In fulfilling its oversight responsibilities, the Audit Committee reviewed and discussed the audited financial statements in the Company’s 2008 Annual Report on Form 10-K with both management and Ernst & Young, which included a discussion of the critical accounting policies and practices used by the Company, and alternative treatments of financial information within generally accepted accounting principles, if any, and their effects, including the treatments preferred by the independent registered public accounting firm, if applicable. In addition, the Audit Committee reviewed all other material communications between the Company and the independent registered public accounting firm.

Management has represented to the Audit Committee that the Company’s internal control over financial reporting is effective. The Audit Committee then reviewed and discussed management’s assessment with management and Ernst & Young. The Audit Committee also discussed with Ernst & Young its report on the Company’s internal control over financial reporting as well as the matters required to be discussed under generally accepted auditing standards, including those matters set forth in Statement on Auditing Standards No. 61, Communication with Audit Committees, as amended, as adopted by the Public Company Accounting Oversight Board in its Rule 3200T.

In addition, the Audit Committee has received and reviewed the written disclosures and letter from Ernst & Young, which are required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent accountant’s communications with the Audit Committee concerning independence and discussed with Ernst & Young the firm’s independence, as well as those disclosures related to the independence of the Company’s independent registered public accounting firm required by the provisions of the Sarbanes-Oxley Act of 2002 and related rules and regulations of the SEC. The Audit Committee has also considered the fees paid to Ernst & Young during the last fiscal year for audit and non-audit services and has determined that the non-audit services provided are compatible with the firm’s independence and are in compliance with applicable law.

The Audit Committee has also discussed with KPMG LLP, which provides internal audit services to the Company, and Ernst & Young, the overall scope and plans for their respective audits. The Audit Committee periodically meets with both firms, with and without management present, to discuss the results of their examinations, the assessments of the Company’s internal control over financial reporting, as well as the overall quality of the Company’s financial reporting.

In reliance on the reviews and discussions referred to above, the Audit Committee recommended to the Board of Directors (which the Board has approved) that the Company’s audited financial statements be included in its Annual Report on Form 10-K for the year ended September 30, 2008 for filing with the SEC. The Audit Committee has also appointed Ernst & Young as the Company’s independent registered public accounting firm for the 2009 fiscal year, which appointment will be submitted to our shareholders for their ratification at our 2009 annual meeting of shareholders.

Audit Committee Pre-Approval Policy

The Audit Committee has adopted a pre-approval policy relating to the provision of both audit and non-audit services by our independent registered public accounting firm, Ernst & Young LLP. Our Audit Committee Pre-Approval Policy provides for the pre-approval of audit, audit-related, tax and other services specifically described in appendices to the policy on an annual basis. Such services are pre-approved up to a specified fee limit. All other permitted services, as well as proposed services exceeding the pre-approved fee limit, must be separately pre-approved by the Audit Committee. Requests for services that require separate approval by the Audit Committee must be submitted to the Audit Committee by both our Chief Financial Officer and the independent auditor and must include a joint statement as to whether, in their view, the request is consistent with the SEC’s rules on auditor independence. The policy authorizes the Audit Committee to delegate to one or more of its members pre-approval authority with respect to permitted services. The Audit Committee did not delegate any such pre-approval authority in fiscal 2008. The Audit Committee pre-approved all of the audit, audit-related and tax fees for services performed by Ernst & Young LLP in fiscal 2008 in accordance with such pre-approval policy. The Audit Committee further concluded that the provision of these services by Ernst & Young LLP was compatible with maintaining its independence. The Audit Committee Pre-Approval Policy is available on the Corporate Governance page of our Web site at www.atmosenergy.com.

COMPENSATION DISCUSSION AND ANALYSIS

Introduction

In this Compensation Discussion and Analysis, we will discuss our executive compensation objectives and strategy, the elements of compensation that we provide to our named executive officers and the analysis we employed in reaching the decisions to pay the specific amounts and types of executive compensation discussed. Later in the proxy statement under the heading “Named Executive Officer Compensation,” beginning on page 31, we have presented a series of tables containing specific information about the compensation paid to or earned by our named executive officers in fiscal 2008, as well as more information on our executive officer compensation programs. The discussion below is intended to assist you in understanding the information provided in the tables and putting that information into context.

Our executive compensation program is built upon the strategy of “Total Rewards,” which we adopted in 1998. Total Rewards is a comprehensive view of the various compensation plans and employee benefits that comprise the total package of compensation that is offered to our officers, including the five named executive officers in this proxy statement, division presidents and other key employees. The Total Rewards strategy is based on the payment of (i) total cash compensation, composed of base salary and annual incentive compensation and (ii) total direct compensation,

20

Table of Contents

composed of total cash compensation and the annualized expected value of long-term incentive compensation awards, being targeted at the 50^th percentile of such compensation for equivalent positions at companies of comparable size in the natural gas distribution business, represented by companies in our proxy peer group and in the energy services industry database, as discussed below. We believe this strategy also fosters a philosophy of “pay for performance” through the use of both annual and long-term incentive plans. Our Total Rewards strategy, in which we limit the use of executive benefits and perquisites, is reviewed each year and updated as needed by the Human Resources Committee (“HR Committee”) with assistance from its independent compensation advisor, the consulting firm of Towers Perrin.

Executive Compensation Objectives and Strategy

Our executive compensation program is designed to ensure that the interests of our executive officers are aligned with those of our shareholders. At the same time, and in consideration of our ownership of regulated natural gas distribution properties and related nonregulated operations, our executive compensation program considers the interests of both our regulated and nonregulated customers. We believe that our executive compensation program is effective in allowing the organization to attract and retain highly-qualified senior management who can deliver outstanding performance.

As discussed above, our executive compensation program is built on the Total Rewards strategy and is founded upon the following principles:

Executive Compensation Consultant

As permitted in its charter, the HR Committee has retained the worldwide consulting firm of Towers Perrin to serve as its independent compensation advisor, which is directly accountable to the committee for the performance of its consulting services. The committee entered into a written

21

Table of Contents

agreement with Towers Perrin to act as its executive compensation advisor and directed Towers Perrin to (i) regularly attend meetings of the committee, (ii) conduct studies of competitive compensation practices and (iii) develop conclusions and recommendations related to the executive compensation plans of the Company for consideration by the committee. Specifically, the HR Committee instructed Towers Perrin to prepare reports and analyses on such matters as the (i) identification of proxy peer group companies, (ii) assessment of competitive compensation for non-employee directors, (iii) review of base salary, annual incentives and long-term incentive compensation opportunities relative to competitive practices for executive compensation and (iv) discussion of emerging issues and trends in executive compensation.

A senior consultant from Towers Perrin generally attends all regularly-scheduled HR Committee meetings, which occurred five times in fiscal 2008. In its role as advisor to the committee, Towers Perrin annually presents reports to the committee on the executive compensation matters discussed above, including benchmarking compensation compared to companies in our proxy peer group and industry, a critique of our incentive compensation plans and recommendations on the establishment of target opportunities for participants in the plans. Towers Perrin also provides to the committee assistance with and guidance regarding performance measures and principles under our incentive compensation plans, as well as advice regarding rules, regulations and developments relating to executive compensation.

Management’s Role in Setting Executive Compensation

The HR Committee and our chairman and chief executive officer, Robert W. Best, met with representatives of Towers Perrin to review and discuss the compensation of all other named executive officers. However, at no time did Mr. Best meet with representatives of Towers Perrin regarding his compensation. The only other executive officer of the Company who regularly works with Towers Perrin is the Senior Vice President, Human Resources. For fiscal 2008, Mr. Best recommended to the committee compensation for Messrs. Reddy, Cocklin, Johnson and Gregory, while Towers Perrin provided to the committee general guidance and competitive compensation data for Mr. Best.

Based upon competitive compensation data, the HR Committee established the compensation levels for the Company’s CEO, Mr. Best. Mr. Best may be present during a portion of the committee’s meetings on executive compensation. However, Mr. Best and any other members of management in attendance at committee meetings are excused when Mr. Best’s compensation is discussed and decisions regarding his compensation are reached by the committee. Messrs. Reddy, Cocklin, Johnson and Gregory attend the committee’s meetings except when compensation of the executive officers is discussed. All decisions by the committee concerning executive compensation levels to be paid to the CEO and named executive officers are subject to approval by the Board.

Competitive Compensation Benchmarking

We operate in a competitive environment for talented executives. Towers Perrin, in its role as the independent compensation consultant to the HR Committee, provided a comprehensive review of the compensation program elements and pay levels for companies with similar business content and of comparable size as measured by annual revenues and market capitalization. The competitive compensation benchmarking included assessments of all elements of compensation for the five named executive officers and most of our other officers, as well as the compensation program for the non-employee directors serving on the Board.

22

Table of Contents

The competitive compensation benchmarking data reviewed by the HR Committee primarily was based on competitive compensation levels and program elements, including base salary, annual incentive compensation and long-term incentive compensation found in the proxy statements filed by 12 public companies with significant natural gas distribution operations (the “proxy peer group”). This set of proxy peer group companies was also used to benchmark annual share utilization data, stock overhang and market capitalization data for long-term incentive compensation analysis. The companies in the proxy peer group were selected because they represent those companies considered by the committee to be the most comparable to the Company in terms of business operations, annual revenues, market capitalization and overall financial performance. The companies in the proxy peer group are selected annually by the committee, after its review of the recommendation of Towers Perrin. The companies in the proxy peer group selected for fiscal year 2008 were as follows:

23

Table of Contents

In order to supplement the executive compensation information derived from its study of the proxy peer group, the HR Committee also considered executive compensation benchmarking data from the Towers Perrin 2007 Energy Services Executive Compensation Database (“energy services industry database”). The companies in this database represent a more diverse set of companies in the energy services industry, including companies in the gas, nuclear and electric utilities industries. In order to adjust for size differences, Towers Perrin employed a statistical analysis (single regression analysis) based on relative total annual revenues to determine competitive pay rates for our named executive officers based upon the data derived from all companies in the Towers Perrin database. The component companies in this database are as follows:

As a secondary source of more general information to assist in its executive compensation level deliberations (rather than for compensation benchmarking purposes), the HR Committee also considered and reviewed proprietary executive compensation information found in the 2007 American Gas Association Compensation Survey and the 2007 Towers Perrin General Industry Executive Compensation Database, comprised of general industry compensation data gathered by Towers Perrin

24

Table of Contents

from over 800 participant companies. Using primarily the proxy peer group compensation analysis, along with the data from the energy services industry database, the committee determined the total targeted level of compensation for each named executive officer that represented the 50^th percentile level for each position. A named executive officer’s base salary, total cash compensation (base salary plus annual bonus) and total direct compensation (base salary plus annual bonus plus annualized long-term incentive compensation) were considered competitive if his targeted level of compensation (for each element as well as total compensation) fell within +/ – 15 percent of the 50^th percentile competitive benchmark amount. The targeted level of compensation of each of our named executive officers fell within such range.

Elements of Executive Compensation

The following discussion contains a description of the various elements of executive compensation we have provided to our named executive officers, as well as an analysis of why we pay each element, how we determine the amount we pay under each element and how each element fits into our overall compensation objectives. Additional information on long-term incentive compensation, as well as retirement and change in control benefits may be found below under “1998 Long-Term Incentive Plan” beginning on page 33.

Base Salary.    The amount of base salary paid to each named executive officer is a major determinant of the amounts of all other elements of compensation paid to our named executive officers. Positions are compared on the basis of job content to similar positions in companies in the proxy peer group and the energy services industry database. Salary ranges are reviewed on an annual basis and proposed salary ranges are reviewed and considered by the HR Committee in October of each year. The midpoint of each salary range is designed to approximate the 50^th percentile of base salaries of such comparable companies. Our Chief Executive Officer provided the committee with an oral presentation discussing his individual performance and contributions, along with a performance evaluation of each named executive officer that reflected individual goals and areas of accountability. Each named executive officer’s final base salary for 2008 was established by the committee after considering the competitive benchmarking data for each position as discussed above, the committee’s subjective evaluation of the performance of each named executive officer, the Company’s overall salary increase budget and related salary increase guidelines established by the Company as well as current economic conditions. Generally, the base salary for each named executive officer, as finally determined by the committee for 2008, was established at or near the salary range midpoint for his pay grade, based upon the factors discussed above. The committee believes that the base salaries as finally determined for each of the named executive officers are competitive with salaries offered for similar positions by companies in our proxy peer group and the energy services industry database and are consistent with our Total Rewards strategy.

Annual Incentive Compensation.    We believe it is important to provide our named executive officers a direct financial incentive to maximize the Company’s financial performance each year. Through our Annual Incentive Plan for Management (“Incentive Plan”), we provide our named executive officers, along with other officers, division presidents and other key management employees, an opportunity to earn an annual bonus based upon the Company’s actual financial performance each year. The Incentive Plan, which has been designed to comply with Section 162(m) of the Internal Revenue Code, is based on our ability to achieve a target level of earnings per share (“EPS”) each year. The EPS performance measurement is the lynchpin of both our annual and long-term compensation programs. The HR Committee believes that EPS is the most appropriate measurement of our financial

25

Table of Contents

performance both on an annual and long-term basis, as it reflects the growth of both our regulated and nonregulated operations and any changes in the value of our shareholders’ investment in the Company. EPS is also one of the most well-known measurements of overall financial performance, which is commonly used by financial analysts as well as the investing public. The committee feels that utilization of this measurement as the basis for our incentive compensation programs maximizes the alignment of the interests of the participants in the Incentive Plan and the 1998 Long-Term Incentive Plan, including our named executive officers, with the interests of our shareholders.

For fiscal 2008, the HR Committee utilized competitive compensation benchmarking data, as discussed above, to establish an annual target opportunity expressed as a percentage of base salary for each participant in the Incentive Plan. The committee has historically used varying percentages for annual target bonus opportunities for all our officers, based on each officer’s particular pay grade, which range from Grades 10-13 for our named executive officers. Our pay grades are based on both the competitive market data as well as the job content and responsibility of each officer position and the potential impact that each officer could have on the operations and financial condition of the Company. The target bonus opportunities for each officer are reviewed each year and benchmarked against the 50^th percentile as described above.

The Incentive Plan targets for fiscal 2008 for each of the five named executive officers were as follows:

At its meeting in October 2007, the HR Committee established the threshold, target and maximum performance levels of EPS presented below, upon which the Incentive Plan’s awards would be based for fiscal 2008. The target EPS goal was based on our annual business plan and budget and took into account such factors in our regulated operations as the allowed rate of return in our established service areas, natural gas pricing and volatility, budgeted capital expenditures, expected growth within our service areas, competitive factors from other service providers and other business considerations embedded in the annual business planning process. The target EPS goal also took into account earnings expected from our nonregulated operations, including earnings from the provision of natural gas management and marketing services to municipalities, other local gas distribution companies and industrial customers as well as the provision of natural gas transportation and storage services to certain of our natural gas distribution divisions and third parties.

The HR Committee set a target EPS goal of $1.94 for fiscal 2008. A threshold level of performance was established at an EPS amount of $1.71. If we had earned an EPS that was less than $1.71, no awards would have been paid to any participant under the Incentive Plan. If we had earned an EPS amount of $1.71 for fiscal 2008, participants in the Incentive Plan would have earned an award equal to 50 percent of their expressed target award (as a specified percentage of base salary). The maximum payout opportunity under the Incentive Plan would have resulted in our named executive officers receiving an award equal to 200 percent of their target award, or a total of 90 to 160 percent of their respective base salaries, depending on

26

Table of Contents

each officer’s pay grade. To achieve a maximum award under the Incentive Plan, we would have had to earn an equivalent of $2.17 in EPS. For our actual performance level attainment, which fell between the target and maximum levels of EPS, straight-line interpolation was used to calculate the level of award.

For fiscal 2008, we earned an EPS of $2.00. This performance attainment resulted in the named executive officers receiving awards equal to 126 percent of their respective target awards. The HR Committee has the discretion under the Incentive Plan to make downward adjustments to earned awards but may not make upward adjustments. For fiscal 2008, the committee did not use its discretion to make negative adjustments to any awards for any participant in the Incentive Plan, including the named executive officers.

For each of the last three fiscal years prior to fiscal 2008, we exceeded our target level of performance based on EPS, with the payouts to participants averaging 110 percent of their target awards each year. Our EPS target levels under the plan have historically increased between 4-6 percent each year and typically have been within the range of announced EPS guidance provided to the public in October or November of each year. The following table is a summary of the performance targets and actual performance attainment for the Incentive Plan for fiscal 2008:

Long–Term Incentive Compensation.    Since fiscal 2004, we have used time-lapse restricted shares with a three-year vesting period and performance-based restricted stock units that are subject to a three-year performance criteria expressed as a cumulative EPS target amount, as our two forms of long-term incentive compensation. The Board awarded grants in April 2008 with approximately 50 percent of the targeted long-term value in the form of time-lapse restricted shares with the remaining 50 percent in the form of performance-based restricted stock units. Typically, the value of the long-term compensation we grant ranges from 80 percent to 150 percent of each named executive officer’s midpoint of their respective salary ranges. All such grants in fiscal 2008 fell within that range for all named executive officers. See the discussion below under “1998 Long-Term Incentive Plan” beginning on page 33 for more information on our long-term incentive compensation and the Grants of Plan-Based Awards table on page 34 for information on the number and value of the grants made in fiscal 2008. We based the actual number and value of awards granted on competitive compensation benchmarking of grants made by the companies in our proxy peer group and the energy services industry database, as discussed above.

The HR Committee believes that the payment of long-term incentive compensation in the form of grants of time-lapse restricted stock promotes and encourages long-term retention and service to the Company and better aligns the interests of our named executive officers with those of our shareholders through increased share ownership. The committee also believes that the grants of performance-based restricted stock units, as measured by cumulative EPS over a three year performance period, provide a balanced approach to long-term compensation by providing more incentive-based opportunities to our named executive officers to reward them based on improved financial performance of the Company.

27

Table of Contents

This approach should also better align the interests of our named executive officers with those of our shareholders through promoting improved financial performance of the Company along with increased share ownership.

With respect to the Company’s actual performance during prior performance periods, grants of performance-based restricted stock units were awarded in May 2005 for the fiscal 2005-2007 performance period. For that period, the Company achieved a cumulative EPS amount of $5.46, compared to the cumulative EPS target amount of $5.30. Since the performance level attained was between target and maximum, straight-line interpolation was used to compute the actual number of performance-based restricted stock units earned. Therefore, the participants, including the named executive officers, earned a total number of performance-based restricted stock units equal to 140 percent of the target plus dividend equivalents, in the form of shares of common stock issued in November 2007.

The Board also awarded grants of performance-based restricted stock units in May 2006 for the fiscal 2006-2008 performance period. The Company achieved a cumulative EPS amount for that period of $5.74 compared to the cumulative EPS target of $5.60. Since the performance level attained was between target and maximum, straight-line interpolation was again used to compute the actual number of performance-based restricted stock units earned. Therefore, the participants, including the named executive officers, earned a total number of performance-based restricted stock units equal to 135 percent of the target plus dividend equivalents in the form of shares of common stock issued in November 2008. The following table sets forth the three-year performance criteria for fiscal 2006-2008:

Performance-Based Restricted Stock Units

Fiscal Years 2006-2008 Cumulative EPS Targets

In addition, the Board awarded grants of performance-based restricted stock units in May 2007 for the fiscal 2007-2009 performance period, which will end on September 30, 2009 and in April 2008 for the fiscal 2008-2010 performance period, which will end on September 30, 2010. As discussed above, the cumulative EPS targets have historically represented a growth in EPS of 4-6 percent per year, on average. Accordingly, the threshold, target and maximum amounts have been increased proportionately for each succeeding performance period.

Retirement Benefits.    Our Pension Account Plan serves as the foundation of retirement benefits for our named executive officers. It is a qualified, cash balance defined benefit pension plan. Benefits under this plan become vested and non-forfeitable after completion of three years of continuous employment. For any named executive officer who retires with vested benefits under the plan, the compensation shown as “Salary” in the Summary Compensation Table on page 31 could be considered eligible compensation in determining benefits.

Our named executive officers also participate in one of two supplemental retirement plans, which provide retirement benefits (as well as supplemental disability and death benefits), at the discretion of our Board of Directors, to all our officers, division presidents and any other employees designated by the Board. A participant in either supplemental plan who has been a participant in the supplemental

28

Table of Contents

retirement plan for at least two years and has attained age 55 is entitled to an annual supplemental pension in an amount that, when added to his or her annual pension payable under the Pension Account Plan, equals 60 percent of his compensation, which will be generally equal to the sum of the amount of the participant’s last annual base salary and the amount of his last award under the Incentive Plan (75 percent of compensation in the case of Mr. Best), subject to reductions for less than ten years of participation in the plan and for retirement prior to age 62. The HR Committee believes that these retirement benefits at the amounts provided are an important component of the total compensation and benefits we provide under our Total Rewards strategy and are critical in ensuring that our overall executive compensation package remains competitive with packages offered by other major public companies in our industry in attracting and retaining highly qualified executives to serve in our named executive officer positions. See the discussion below under “Retirement Plans” beginning on page 37 for more information on our retirement benefits.

Change in Control Benefits.    We have entered into severance agreements with each of the named executive officers to provide certain severance benefits for them in the event of the termination of their employment within three years following a “change in control” of the Company (as defined in the severance agreements and described generally below under “Change in Control Severance Agreements” beginning on page 39). The severance agreement for each named executive officer generally provides that the Company will pay such officer as severance pay in one lump sum an amount equal to (a) 2.5 times his total compensation (annual base salary and average amount of annual incentive compensation received under the Incentive Plan) and (b) the total of (i) an amount that is actuarially equivalent to an additional three years of annual age and service credits payable to the officer under the Company’s Pension Account Plan and (ii) an amount that is actuarially equivalent to an additional three years of Company matching contributions payable to the officer under the Company’s Retirement Savings Plan and Trust. If such lump sum severance payment results in the imposition of excise taxes imposed by Section 4999 of the Internal Revenue Code, the lump sum severance payment will be increased in an amount required for the executive officer to pay any such excise taxes or any resulting income or other taxes due to the Internal Revenue Service. We provide these change in control severance benefits to our named executive officers because the HR Committee believes it is important to offer a certain degree of financial security to our highly qualified executives in the event of organizational and personnel changes that frequently follow a change in control. The provision of such benefits at the amounts provided is necessary to remain competitive with other major public companies in our industry and continue to attract and retain highly qualified executives to serve in our named executive officer positions.

Share Ownership Guidelines

We have adopted share ownership guidelines for our named executive officers, along with other officers and division presidents, which are voluntary and are intended to be achieved by each such executive over the course of five years. The HR Committee strongly advocates executive share ownership as a means by which to better align the interests of our executives with those of our shareholders and monitors compliance with the ownership guidelines each year. The Chief Executive Officer has a guideline to reach a share ownership position of five times his base salary over the course of five years, with each of the remaining named executive officers having a share ownership guideline to reach a share ownership position of 2.5 times base salary. The share ownership positions include shares of unvested time-lapse restricted stock but do not include stock options or unvested performance-based restricted stock units. In addition, any shares that an executive officer may own subject to a market put or call option are excluded for purposes of determining compliance with our share ownership guidelines. We do not have a formal policy prohibiting transactions in which an

executive officer may hedge his economic risk of owning shares of our common stock or in which such officer may pledge or create a security interest in our common stock. However, each executive officer must obtain prior clearance from our Corporate Secretary or General Counsel for all transactions involving our common stock, prior to engaging in such transactions, including any hedging or pledging transaction, in order to ensure compliance with applicable laws. Each of the named executive officers has achieved his individual ownership objective.

Additional Information

The compensation of our Chief Executive Officer, Mr. Best, is higher than that of any of our other named executive officers, primarily in recognition of his level of responsibility and the competitive market data for chief executive officers of comparably-sized natural gas distribution companies in our proxy peer group and the energy services industry database. However, Mr. Best, as the Chief Executive Officer, participates in all the same compensation plans as the other officers and division presidents and is subject to the same performance measurement determinations under the incentive compensation plans. We do not have any individual compensation policies or plans that are not applied consistently to all of our officers and division presidents. We also do not have a policy under which the annual levels of compensation, and the grant of both Incentive Plan and LTIP awards, are adjusted each year to reflect the projected gains that may be realized by an executive officer from stock-based compensation. Each year, the establishment of target opportunities in incentive compensation is based solely upon competitive market conditions and the other factors discussed above.

1998 Long-Term Incentive Plan

To provide our named executive officers, other officers, division presidents and other key management employees with the incentive to achieve our long-term growth and profitability goals, as well as to focus upon the creation of shareholder value, the HR Committee makes recommendations to the Board concerning grants of long-term incentive awards under our 1998 Long-Term Incentive Plan (“LTIP”).

For the last several years, the HR Committee has recommended all annual long-term incentive grants at its regularly scheduled March meeting, which are approved by the Board at its regularly scheduled May meeting. In addition, when an award is granted in connection with a pre-established performance goal, the committee has approved the performance goal and the related compensation formula within the first 90 days of the fiscal year. Each year, prior to making grants, the committee establishes a target long-term incentive value for the LTIP participants, including the named executive officers. The actual value of grants ultimately received by participants may differ from the intended value or target long-term incentive value granted, depending upon share price performance and any performance considerations imposed upon such awards.

No options have been granted to any participants since fiscal 2003 although they may still be granted under the terms of the LTIP. However, some participants did receive options in fiscal 2004 and 2005 pursuant to their election to convert all or a portion of their incentive compensation received under the Incentive Plan in those years, which election is no longer allowed under the Incentive Plan. Options may be exercisable in full at the time of grant or may become exercisable in one or more installments. Options are exercisable for a period of ten years after the date of grant of the option. Since October 1, 2007, at least 25 percent of the number of shares of common stock acquired through the exercise of any options granted after that date may not be sold or otherwise transferred by the participant for at least one year after the date of exercise.

In the event of termination of service, the options lapse 90 days after said termination, except in the case of retirement, in which case the retiring participant may exercise the options at any time within three years from the date of retirement. In the event of death, the options may be exercised by the personal representative of the optionee at any time within three years from the date of death. As discussed above under Long-Term Incentive Compensation in our “Compensation Discussion and Analysis” beginning on page 27, since fiscal 2004, we have used time-lapse restricted shares and performance-based restricted stock units as our form of long-term incentive compensation. All restrictions lapse on time-lapse restricted shares at the conclusion of the third year following the date of grant, except for any grants that may be made by our Board in connection with the appointment of an officer. Dividends are paid on all time-lapse restricted shares after the date of grant during the period before the restrictions have lapsed at the same rate as other shares. Once the restrictions have lapsed, the participant will take full ownership of the shares, net of shares withheld for taxes, provided that he is an employee of the Company at that time.

Performance-based restricted stock units are subject to a three-year performance criteria expressed as a cumulative EPS target amount. The EPS target is derived from our annual business plan and represents the same EPS target at the time of grant as that used under the Incentive Plan; the EPS targets added to the Incentive Plan’s target EPS for the second and third years have historically represented a growth in EPS of 4-6 percent each year, on average. At the conclusion of the three-year performance period, the total number of performance-based restricted stock units to be issued is determined by a formula with established threshold, target and maximum number of restricted stock

units earned, ranging from 0 percent to 150 percent of the value of the performance-based restricted stock units granted, based on the cumulative amount of EPS achieved over the three-year performance period. Although our LTIP provides that cash, shares of our common stock or a combination thereof may be issued to participants in payment for their units, to date, we have always paid participants for their units in the form of shares of our common stock at the end of each three-year performance period. In addition, dividend equivalents are credited to each participant’s account with respect to the performance-based restricted stock units beginning at the date of grant, with the payment of such dividend equivalents in the form of additional shares of stock not occurring until the three-year cumulative EPS performance targets are measured and vesting is completed.

Retirement Plans

Pension Account Plan.    Our Pension Account Plan is a qualified, cash balance defined benefit pension plan under both the Internal Revenue Code and the Employee Retirement Income Security Act of 1974, as amended. The plan covers substantially all of our employees (other than employees of Atmos Energy Holdings, Inc.), including all named executive officers. Benefits under this plan become vested and non-forfeitable after completion of three years of continuous employment. A vested participant receives the monthly retirement benefit at normal retirement age under the retirement plan, unless an early retirement benefit is elected, in which case the retirement benefit may be actuarially reduced for early commencement. Participants retiring on or after age 65 receive 100 percent of their accrued monthly benefit, which may be reduced depending on the optional form of payment elected at retirement. Benefits payable under our retirement plan are not offset by social security benefits. Under the Internal Revenue Code, the annual compensation of each employee to be taken into account under our retirement plan for 2008 cannot exceed $230,000.

The earnings utilized in the Pension Account Plan includes W-2 earnings, 401(k) deferrals and Internal Revenue Code Section 125 (“cafeteria plan”) reductions, while it excludes all incentive pay and expense reimbursements. All participants are fully vested in their account balances after three years of eligible service and may choose to receive their account balances in the form of a lump sum or an annuity. For any named executive officer who retires with vested benefits under the plan, the compensation shown as “Salary” in the Summary Compensation Table on page 31 could be considered eligible compensation in determining benefits.

Supplemental Plans.    Mr. Best also participates in the Company’s Supplemental Executive Benefits Plan (“SEBP”), while Messrs. Reddy, Cocklin, Johnson and Gregory participate in the Company’s Supplemental Executive Retirement Plan, formerly known as the Performance-Based Supplemental Executive Benefits Plan (“SERP)” (collectively, the “Supplemental Plans”), which provide retirement benefits (as well as supplemental disability and death benefits) to all officers, division presidents and other employees, all as approved by the Board. An officer or division president (or any other employee selected by the Board) who has participated in the SERP for at least two years and has attained age 55 is entitled to an annual supplemental pension in an amount that, when added to his or her annual pension payable under the Pension Account Plan, equals 60 percent of his compensation, subject to reductions for less than ten years of participation in the plan and for retirement prior to age 62. Mr. Best is entitled to 75 percent of his compensation under the SEBP.

Table of Contents

The Supplemental Plans cover compensation in an amount equal to the sum of (a) the greater of the participant’s annual base salary at the date of termination of employment or the average of the participant’s annual base salary for the highest of three calendar years (whether or not consecutive) of employment with the Company; and (b) the greater of the amount of the participant’s last award under any of the Company’s annual performance bonus or incentive plans or the average of the participant’s highest three performance awards under such plans (whether or not consecutive). The amount of current compensation covered by the Supplemental Plans as of the end of fiscal 2008 for each of the named executive officers listed in the Summary Compensation Table is as follows: Robert W. Best, $1,663,200; John P. Reddy, $707,478; Kim R. Cocklin, $680,309; Mark H. Johnson, $614,098 and Louis P. Gregory, $477,044. Each of such named executive officers has the following approximate number of years of credited service under the retirement plans: Mr. Best, 11 years; Mr. Reddy, ten years; Mr. Cocklin, two years; Mr. Johnson, three years and Mr. Gregory, eight years.

Each of the named executive officers has also entered into a Participation Agreement with the Company as required by the Supplemental Plans. Each of the Supplemental Plans provides that the accrued benefits, as calculated pursuant to the plan, of each participant will vest if: (a) the plan is terminated by the Company; (b) the plan is amended by the Company, resulting in a decrease in the benefits otherwise payable to the participant; (c) the participant’s employment is terminated by the Company for any reason other than “cause”; (d) the participant’s participation in the plan is terminated by the Company for any reason other than “cause” prior to the participant’s termination of employment; (e) within any time during the three year period following a “change of control” of the Company (as such term is defined in the plan), (i) the participant’s employment is terminated involuntarily by the Company for any reason other than “cause” or (ii) the participant is demoted or reassigned to a position that would cause him to cease to be eligible for participation in the plan; or (f) in anticipation of a “change in control” (whether or not a “change in control” ever occurs), (i) the participant’s employment is terminated involuntarily by the Company for any reason other than “cause” at the request of a party to a pending transaction that would constitute a “change in control”, if and when the transaction were consummated or (ii) the participant’s participation in the plan is terminated for any reason other than “cause” prior to the participant’s termination of employment. The Participation Agreements set forth the specific rights of the participants to their accrued benefits upon the occurrence of the events described above and constitute enforceable contracts separate from the provisions of the Supplemental Plans.
