These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan at December 31, 2002 and 2001, and the changes in its net assets available for benefits for the year ended December 31, 2002, in conformity with accounting principles generally accepted in the United States. Our audits were performed for the purpose of forming an opinion on the financial statements taken as a whole. The accompanying supplemental schedules of assets (held at end of year) as of December 31, 2002, and reportable transactions for the year then ended, are presented for purposes of additional analysis and are not a required part of the financial statements but are supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. These supplemental schedules are the responsibility of the Plan's management. The supplemental schedules have been subjected to the auditing procedures applied in our audits of the financial statements and, in our opinion, are fairly stated in all material respects in relation to the financial statements taken as a whole. /s/ ERNST & YOUNG LLP Dallas, Texas June 11, 2003 ATMOS ENERGY CORPORATION RETIREMENT SAVINGS PLAN AND TRUST (FORMERLY ATMOS ENERGY CORPORATION EMPLOYEE STOCK OWNERSHIP PLAN AND TRUST) STATEMENTS OF NET ASSETS AVAILABLE FOR BENEFITS December 31 ----------- ----------- 2002 2001 ----------- ----------- ASSETS ------ Investments: Common stock of Atmos Energy Corporation $57,217,105 $48,502,656 Registered Investment Companies: T.

DESCRIPTION OF THE PLAN The following brief description of the Atmos Energy Corporation Retirement Savings Plan and Trust (formerly Atmos Energy Corporation Employee Stock Ownership Plan and Trust) (the Plan) is provided for general information only. Participants should refer to the Summary Plan Description for a more complete description of the Plan's provisions. GENERAL The Plan is a trusteed defined contribution retirement benefit plan offered to eligible employees of Atmos Energy Corporation (the Company or Atmos). The Plan is to continue for an indefinite term and may be amended or terminated at any time by the Board of Directors of Atmos (the Board). The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended (ERISA). ELIGIBILITY Substantially all employees of the Company (except employees covered by other agreements, leased employees and any employees covered by a collective bargaining agreement in which Plan participation has not been negotiated through good faith bargaining) (Participants) are eligible to participate in the Plan as of the first payroll period coincident with or immediately following the date of hire. CONTRIBUTIONS Contributions to the Plan include contributions withheld by the Company on behalf of each Participant in an amount specified by the Participant pursuant to a salary reduction agreement, as well as matching Company contributions and any discretionary Company contributions. Participants are eligible to receive matching Company contributions after completing at least one year of service, effective on the earlier of January 1, April 1, July 1 or October 1 after which one year of service has been completed. 4 1. DESCRIPTION OF THE PLAN (CONTINUED) Participants may elect a salary reduction (not to exceed $11,000 in 2002 or $12,000 for those participants age 50 or older), ranging from a minimum of 1% up to a maximum of 65% of eligible compensation, as defined by the Plan, not to exceed the maximum allowed by the Internal Revenue Service (IRS). The Company shall contribute a matching Company contribution in an amount equal to 100% of each Participant's salary reduction contribution, up to a maximum of 4% of such Participant's eligible compensation for the Plan year. The Company's matching contribution meets the current IRS "Safe Harbor" definition. The Company may revoke or amend any Participant's salary reduction agreement if necessary to ensure that (1) each Participant's additions for any year will not exceed applicable IRS Code (the Code) limitations and (2) Company matching contributions will be fully deductible for federal income tax purposes. The Plan also provides that a discretionary contribution may be made at the option of the Board and in an amount determined annually by the Board. No discretionary contribution was made to the Plan in 2002. All contributions to a Participant's account are immediately and fully vested. INVESTMENT OPTIONS The Plan allows Participants' salary reduction contributions to be invested among a variety of registered investment companies, one common/collective trust and Atmos common stock. The Stock Purchase Program Fund, consisting of Atmos common stock, is non-participant and participant directed. All Company matching and discretionary contributions are directed into this fund and may not be transferred to another investment option until the plan year following the year a Participant reaches age 55. In any plan year subsequent to a Participant reaching age 55, a Participant will have the opportunity, during the first calendar quarter, to diversify, in a one-time election, his or her Atmos common stock into other available investment options. Prior to March 1, 2002, contributions made to this fund by Participants could be transferred to other investment options during the last two weeks (14 calendar days) of each calendar quarter with the actual transfer taking place on the first business day after the start of the next calendar quarter. Effective March 1, 2002 contributions made to this fund by Participants are allowed to be diversified at any time into one or more of the other investment options offered by the Plan. Effective January 1, 2003, Company matching and discretionary contributions directed into this fund are allowed to be diversified at any time after the contribution is made into one or more of the other investment options offered by the Plan. 5 1. DESCRIPTION OF THE PLAN (CONTINUED) In May 2000, the Company completed the acquisition of the Missouri natural gas distribution assets of Associated Natural Gas (ANG) from a subsidiary of Southwestern Energy Corporation. Employees of ANG that joined the Company were allowed to transfer into the Plan his or her assets which were held in the Southwestern Energy Corporation 401(k) Plan (the Southwestern Plan). To accommodate several ANG employees who held Entergy Corporation (Entergy) common stock in the Southwestern Plan, an additional account was established in the Plan to hold the Entergy stock. This account was established as a frozen account where funds can be liquidated but no new stock added. In July 2001, the Company completed the acquisition of the assets of Louisiana Gas Service Company and LGS Natural Gas Company (LGS) from Citizens Communications Company, formerly Citizens Utilities Company. Substantially all employees of LGS who joined the Company were immediately eligible to participate in the Plan. Employees of LGS that joined the Company were allowed to rollover into the Plan their assets which were held in the Citizens Utilities Company 401(k) Employee Benefit Plan (the Citizens Plan). To accommodate several LGS employees who held Citizens Communications Company (Citizens) Class B common stock in the Citizens Plan, an additional account was established in the Plan to hold the Citizens stock. This account was established as a frozen account where funds can be liquidated but no new stock added. DISTRIBUTIONS TO PARTICIPANTS Effective March 1, 2002, dividends received on Atmos common stock will automatically be reinvested in Atmos common stock. However, a Participant may elect to have his or her dividends paid in cash. This election may be made at any time during the period beginning on the first business day on or after the dividend record date and ending at a time specified by the Retirement Savings Plan Committee (formerly Employee Stock Ownership Plan Committee) (the Committee) on the last business day preceding the dividend payout date. Cash dividends received on Atmos common stock, in accordance with the Plan, must be distributed to Participants no later than 90 days after the Plan's year end. Currently, the dividends are distributed quarterly. Once a Participant elects to receive his or her dividends in cash, the election will remain in effect until the election is changed. 6 1. DESCRIPTION OF THE PLAN (CONTINUED) A Participant may elect to receive an annual distribution of Company matching or discretionary contributions made to his or her account prior to January 1, 1999 and which were allocated to his or her account at least two years prior to such election. These annual elections are made as of January 1. The annual distribution from the Plan is normally made in February of the following year. Company matching or discretionary contributions made after January 1, 1999 meet the current IRS "Safe Harbor" definition and are not eligible for in-service withdrawal. In the event of retirement, death, termination due to disability or termination of employment for another reason, a Participant is entitled to withdraw the entire amount from each of his or her accounts. Withdrawals from a Participant's salary reduction account, as well as the Company matching and discretionary accounts, are also allowed upon proof of financial hardship meeting IRS "Safe Harbor" definitions or, if elected, subsequent to the Participant attaining age 59 1/2. Withdrawals from the Stock Purchase Program Fund may be in the form of Atmos common stock or cash, as determined by the Committee. However, a Participant has the right to have withdrawals made in the form of Atmos common stock upon written notice by the Participant. LOANS TO PARTICIPANTS A Participant may borrow up to the lesser of $50,000 or 50% of his or her account balance, with a minimum loan amount of $1,000. Loans are repaid through payroll deductions over periods of up to 5 years for general purpose loans or 15 years for primary residence loans. The interest rate is the U.S. prime rate plus 2% and is fixed over the life of the loan. A Participant may have a maximum of two loans outstanding at any one time. If a Participant has an outstanding loan in force and terminates his or her employment, the Participant may elect to continue to pay the loan according to the payment schedule that was set up at the time the loan was initiated. If this option is elected, the Participant must also leave his or her account balance in the Plan. A second option is that the Participant may elect to have the outstanding loan balance treated as a distribution from the Plan. A third option is that the Participant may repay the loan in full prior to his or her termination of employment. PLAN TERMINATION While the Company has not expressed any intent to terminate the Plan, it is free to do so at any time. In the event of the dissolution, merger, consolidation or reorganization of the Company, the Plan shall terminate and the trust shall be liquidated, unless the Plan is continued by a successor. Upon such liquidation, all accounts shall be distributed to the Participants. 7 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES BASIS OF PRESENTATION The financial statements of the Plan are prepared on the accrual basis of accounting. Distributions to participants are recorded when paid. USE OF ESTIMATES The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. INVESTMENT VALUATION AND INCOME RECOGNITION Shares of registered investment companies are valued at published market prices which represent the net asset value of shares held by the Plan at year end. Investments in common stock are valued at quoted market prices. The fair value of investments in the common/collective trust are determined periodically by T. Rowe Price Associates, Inc. based upon the current fair value of the underlying assets of the fund. The fair value of participant loans are valued at cost which approximates fair value. Purchases and sales of securities are recorded on a trade date basis. Investment income is recorded on the accrual basis and dividend income is recorded on the ex-dividend date. Realized gains and losses from security transactions are reported on the average historical cost method. Capital gains and losses are included in interest and dividend income. 3. ADMINISTRATION OF THE PLAN AND PLAN ASSETS The Plan is administered by the Committee, consisting of at least three persons who are appointed by the Board. The members of the Committee serve at the pleasure of the Board without compensation. Certain administrative functions are performed by employees of the Company. No employee of the Company receives compensation from the Plan. In accordance with the Plan, the Company has appointed the Committee as Trustee of the Plan. The Trustee may be removed at the discretion of the Board. The Trustee shall vote any common stock held in the trust in accordance with directions received from the Participants, or at its discretion if there are no such directions. The Plan's assets are held by T. Rowe Price Associates, Inc., the Custodian and Recordkeeper of the Plan. All expenses of the Plan are paid by the Company except for processing fees related to loan withdrawals. 8 4. NON-PARTICIPANT DIRECTED INVESTMENTS Atmos common stock held in the Stock Purchase Program Fund prior to January 1, 2003 was non-participant and participant directed. The investment activity for the year ended December 31, 2002 related to Atmos common stock cannot be segregated between non-participant and participant directed. The following presents the information about the net assets and the components of the changes in net assets relating to the Atmos common stock, of which a portion is non-participant directed: December 31 --------------------------- 2002 2001 ----------- ----------- Investments: Atmos Energy Corporation Common Stock $57,217,105 $48,502,656 =========== =========== Year ended December 31, 2002 --------------- Changes in net assets: Contributions $ 6,562,038 Dividends 2,765,092 Interest on participant loans 158,840 Loan repayments 764,221 Net appreciation in fair value of investments 4,916,362 Distributions to participants (5,389,605) Interfund transfers out (1,062,499) --------------- $ 8,714,449 =============== 9 5. INVESTMENTS Investments that represent 5% or more of the Plan's net assets available for benefits are separately identified in the statements of net assets available for benefits. The Plan provides for investments in various investment securities which, in general, are exposed to various risks, such as interest rate, credit, and overall market volatility risks. Further, due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect the amounts reported in the statements of net assets available for benefits. During 2002, the Plan's investments (including investments purchased and sold, as well as held during the year) appreciated/(depreciated) in fair value as determined by quoted market prices for common stock and published market prices for registered investment companies as follows: Atmos Energy Corporation Common Stock $ 4,916,362 Registered Investment Companies: T.

INCOME TAX STATUS The Plan has received a determination letter from the IRS dated November 1, 2002 stating that the Plan is qualified under Section 401(a) of the Code and, therefore, the related trust is exempt from taxation. Subsequent to the issuance of the determination letter, the Plan was amended. Once qualified, the Plan is required to operate in conformity with the Code to maintain its qualification. The Plan administrator believes the Plan is being operated in compliance with the applicable requirements of the Code and, therefore, believes that the Plan is qualified and the related trust is tax-exempt. 11 8. SUBSEQUENT EVENT In December 2002, the Company completed the acquisition of Mississippi Valley Gas Company (MVG). At the time of acquisition, MVG had two defined contribution plans covering substantially all full-time employees. The first plan was the Mississippi Valley Gas Company Savings Plan (the MVG Plan) and the second plan was the Mississippi Valley Gas Company Savings Plan for Gas Employees Independent Union (the MVG Union Plan). Effective December 21, 2002, all participants (approximately 300) in the MVG Plan were eligible to participate in the Plan. On May 1, 2003, the assets of the MVG Plan were transferred into the Plan. Negotiations have not been completed regarding the union employees' participation in the Plan. 12 ATMOS ENERGY CORPORATION RETIREMENT SAVINGS PLAN AND TRUST (FORMERLY ATMOS ENERGY CORPORATION EMPLOYEE STOCK OWNERSHIP PLAN AND TRUST) SCHEDULE H; LINE 4i SCHEDULE OF ASSETS (HELD AT END OF YEAR) EIN: 75-1984576 PLAN NUMBER: 002 December 31, 2002 (c) Description of investment (b) Identity of issue, including maturity date borrower, lessor rate of interest, collateral, (e) Current (a) or similar party par or maturity value (d) Cost value --------- ------------------------------- -------------------------------- ----------------- -------------- * Atmos Energy Corporation Common stock; 2,453,564 shares $ 48,095,684 $ 57,217,105 * T.
