    REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


    To the Participants and the Qualified Retirement Plans and Trusts Committee of the
    Atmos Energy Corporation Retirement Savings Plan and Trust

    Opinion on the Financial Statements

    We have audited the accompanying statements of net assets available for benefits of the Atmos Energy Corporation Retirement Savings Plan and Trust (the "Plan") as of December 31, 2024 and 2023, and the related statement of changes in net assets available for benefits for the year ended December 31, 2024, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2024 and 2023, and the changes in net assets available for benefits for the year ended December 31, 2024, in conformity with accounting principles generally accepted in the United States of America.

    Basis for Opinion

    These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on the Plan’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Plan in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

    We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.

    Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

    Supplemental Information

    The supplemental information in the accompanying schedule of Form 5500, Schedule H, Line 4i – Schedule of Assets (Held at End of Year) as of December 31, 2024, has been subjected to audit procedures performed in conjunction with the audit of the Plan’s financial statements. The supplemental information is the responsibility of the Plan’s management. Our audit procedures included determining whether the supplemental information reconciles to the financial statements or the underlying accounting and other records, as applicable, and performing procedures to test the completeness and accuracy of the information presented in the supplemental information. In forming our opinion on the supplemental information, we evaluated whether the supplemental information, including its form and content, is presented in conformity with the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. In our opinion, the supplemental information is fairly stated, in all material respects, in relation to the financial statements as a whole.

    ATMOS ENERGY CORPORATION RETIREMENT
    SAVINGS PLAN AND TRUST

    NOTES TO FINANCIAL STATEMENTS
    December 31, 2024



    1. Description of the Plan
    The following brief description of the Atmos Energy Corporation Retirement Savings Plan and Trust (the Plan) is provided for general information only. Participants should refer to the Summary Plan Description for a more detailed 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, Atmos Energy or Plan Sponsor). 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 Energy (the Board). The Plan is administered by the Qualified Retirement Plans and Trusts Committee (the Committee), which is appointed by 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, other than leased employees (Participants), are automatically enrolled in the Plan at a pre-tax salary deferral rate of four percent (4%) of their compensation. Participants have a 30-day period to opt out of automatic enrollment. After 30 days, if the Participant has not opted out or elected a different deferral percentage, salary deferrals begin at the automatic enrollment level of 4%. Effective January 1, 2025, the automatic enrollment level increased from 4% to 5%, and effective January 1, 2026, it will increase from 5% to 6%.
    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 deferral agreement, as well as matching and fixed annual Company contributions.
    Participants may elect a Pre-Tax or Roth deferral rate ranging from a minimum of one percent (1%) up to a maximum of 65 percent (65%) of eligible compensation, as defined by the Plan, not to exceed the maximum allowed by the Internal Revenue Code (the Code) ($23,000 in 2024 or $30,500 for those participants age 50 or older). Additionally, the Plan includes an automatic increase provision where each Participant who contributes less than 10% as an elective pre-tax deferral will have their contribution percent increased by 1% each Plan year unless the Participant opts out of the automatic increase feature.
    The Company contributes a matching Company contribution in an amount equal to 100 percent of each Participant’s salary deferral contribution, up to a maximum of 4% of such Participant’s eligible compensation, as defined by the Plan, for the Plan year. The Company’s matching contribution meets the current Internal Revenue Service (IRS) “Safe Harbor” definition. The Company may revoke or amend any Participant’s salary deferral agreement if necessary to ensure that (1) each Participant’s salary deferrals for any year will not exceed applicable Code limitations and (2) Company matching contributions will be fully deductible for federal income tax purposes. The Company matching contributions are in accordance with the Participant's investment elections, subject to a 25 percent limit for Atmos Energy common stock as described below. For the year ended December 31, 2024, the Company made matching Company contributions of $18,089,882. Effective January 1, 2025, the Company increased the matching Company contribution from 4% to 5%, and effective January 1, 2026, the Company will increase it from 5% to 6%.
    Additionally, employees who joined the Plan subsequent to September 30, 2010 receive a fixed annual Company contribution of 4% of eligible compensation to their Plan account. During the year ended December 31, 2024, the Company made fixed annual contributions of $9,839,047.
    Participants are eligible to receive matching contributions immediately upon entering the Plan. Participants are eligible to receive fixed annual Company contributions after completing at least one year of service, effective on the first full pay period after which one year of service has been completed. Employee deferral contributions are immediately and fully vested, while the Company's matching contributions fully vest after one year of service and the fixed annual Company contributions fully vest after three years of service.
    The Plan allows for in-plan rollovers and permits elective deferrals, including Roth, to be rolled into the Plan.

    SAVINGS PLAN AND TRUST

    NOTES TO FINANCIAL STATEMENTS (continued)

    Forfeitures
    Forfeitures are first used to fund any restorations of previously forfeited fixed annual Company contributions of former participants that are rehired. Any remaining forfeitures are used to reduce fixed annual Company contributions.
    Investment Options
    The Plan allows Participant salary deferral contributions to be invested among a variety of registered investment companies, one common/collective trust (CCT) and Atmos Energy common stock.
    Investments in Atmos Energy common stock are participant directed. All Participant and Company contributions made in Atmos Energy common stock 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.
    To help participants achieve better diversification, a participant's investment elections may not have an allocation greater than 25 percent to Atmos Energy common stock. In addition, future exchanges or rollovers into Atmos Energy common stock will be limited to 25 percent of the participant's total account balance. After a participant reaches the 25 percent limit, future contributions will be made in cash according to the participant's other investment elections.
    Distributions to Participants
    Dividends received on Atmos Energy common stock are automatically reinvested in Atmos Energy common stock. However, a Participant may elect to receive 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 Committee on the last business day preceding the dividend payout date. Cash dividends received on Atmos Energy 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 dividends in cash, the election will remain in effect until the election is changed.
    In the event of retirement, death, termination due to disability or termination of employment for another reason, a Participant, or beneficiary in the event of death, is entitled to withdraw their account from the Plan. At the time of termination, Participants who do not have Plan loans outstanding are entitled to take one or more partial distributions from their account.
     
    Withdrawals from a Participant’s salary deferral account are allowed upon proof of financial hardship meeting IRS “Safe Harbor” definitions. Hardship withdrawals are not permitted from the Company matching or fixed annual Company contribution accounts.
    If elected, subsequent to the Participant attaining age 59 1/2, withdrawals may be made from a Participant’s salary deferral account as well as the vested portion of the Company matching account; however, withdrawals may not be made from the fixed annual Company contribution account. Withdrawals of investments in Atmos Energy common stock may be in the form of Atmos Energy common stock or cash, as determined by the Committee, at the Participant's discretion.
    A Participant may elect to receive a distribution of non-safe harbor prior company matching or discretionary contributions made to their account at least two years prior to such election. Safe harbor Company matching contributions meet the current IRS “Safe Harbor” definition and are not eligible for in-service withdrawal.
    Effective January 1, 2024, the Company amended and restated the Plan to comply with certain required and optional provisions of the SECURE Act 2.0 that had various administrative impacts relating to distributions.
    Loans to Participants
    A Participant may borrow up to the lesser of $50,000 or 50 percent of their account balance, with a minimum loan amount of $1,000. Loans are repaid through payroll deductions over periods of up to five years for general purpose loans or 15 years for primary residence loans. The interest rate is the U.S. prime rate plus 2 percent and is fixed over the life of the loan. A Participant may only have one loan outstanding.
    If a Participant has an outstanding loan in force and terminates 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 their account balance in the Plan. Under a second option, the Participant may elect to have the outstanding loan

    NOTES TO FINANCIAL STATEMENTS (continued)

    balance treated as a distribution from the Plan. A third option provides that the Participant may repay the loan in full within the date range established by IRS rules and stated in the Plan's loan policy.
    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 will terminate and the trust will be liquidated, unless the Plan is continued by a successor. Upon such liquidation, all accounts shall be fully vested and will be distributed to the Participants.
    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 fair value based on published market prices, which represents the net asset value of shares held by the Plan at year end. Investments in common stock are valued at fair value based on quoted market prices.
    The CCT is comprised primarily of fully benefit-responsive investment contracts, which include conventional, synthetic and separate account investment contracts issued by life insurance companies, banks and other financial institutions, designed to provide principal stability and a competitive yield. The CCT is valued at the net asset value of units of the T. Rowe Price Trust Company (T. Rowe Price) collective trust. The net asset value is used as a practical expedient to estimate fair value. The practical expedient would not be used if it is determined to be probable that the fund will sell the investment for an amount different from the reported net asset value. Participant transactions (purchases and sales) may occur daily. If the Plan initiates a full redemption of the collective trust, the issuer reserves the right to require 12 months' notification in order to ensure that securities liquidations will be carried out in an orderly business manner.
    The fair value methods described may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Committee believes the valuation methods used are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain assets could result in a different fair value measurement at the measurement date.
    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 securities transactions are reported on the average historical cost method. Capital gains and losses are included in interest and dividend income.
    Notes Receivable from Participants
    Notes receivable from participants represent Participant loans that are recorded at their remaining outstanding balance plus any accrued but unpaid interest. Interest income on notes receivable from participants is recorded when earned.
    Subsequent Events
    We have evaluated subsequent events from the December 31, 2024 statement of net assets available for benefits date through June 26, 2025, the date these financial statements were issued. Except as noted throughout Note 1 to the financial statements regarding various Plan amendments, no events occurred subsequent to the statement of net assets available for benefits date that would require recognition or disclosure in the financial statements.

    ATMOS ENERGY CORPORATION RETIREMENT
    SAVINGS PLAN AND TRUST

    NOTES TO FINANCIAL STATEMENTS (continued)

    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 appointment of the Board without compensation from the Plan. 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, the custodian and recordkeeper of the Plan.
    Generally, administrative expenses of the Plan are paid by the Company except for processing fees related to loans to participants, which are paid by the Participant.
    4. Fair Value Measurements
    Authoritative accounting literature establishes a fair value hierarchy that prioritizes the inputs used to measure fair value based on observable and unobservable data. The hierarchy categorizes the inputs into three levels, with the highest priority given to unadjusted quoted prices in active markets for identical assets and liabilities (Level 1) and the lowest priority given to unobservable inputs (Level 3). The asset’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. The levels of the hierarchy are described below:
    Level 1 — Unadjusted quoted prices in active markets for identical assets or liabilities. An active market for the asset is defined as a market in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis. The Plan’s Level 1 measurements consist of registered investment companies (mutual funds) and common stock.
    Level 2 — Inputs other than quoted prices included in Level 1 that are either directly or indirectly observable for the asset as of the reporting date. These inputs are derived principally from, or corroborated by, observable market data. Currently, the Plan has no assets recorded at fair value that would qualify for Level 2 reporting.
    Level 3 — Unobservable inputs that are supported by little, if any, market activity and are significant to the fair value of the assets as of the measurement date. Currently, the Plan has no assets recorded at fair value that would qualify for Level 3 reporting.
     
    The Plan records accounts receivable and accounts payable at carrying value, which substantially approximates fair value due to the short-term nature of these assets.

    5. Related Party and Party-in-Interest Transactions
    Certain Plan investments in registered investment companies and a common/collective trust fund are managed by T. Rowe Price. T. Rowe Price is the custodian and recordkeeper; therefore, these transactions qualify as party-in-interest transactions. Additionally, certain Plan participants have invested in Atmos Energy common stock. Because the Company is the Plan Sponsor, transactions involving Atmos Energy common stock qualify as party-in-interest and related party transactions. The Plan also issues loans to participants. All of these party-in-interest transactions are exempt from the prohibited transaction rules. At December 31, 2024 and 2023, participant accounts held 1,852,747 and 2,065,814 shares of Atmos Energy common stock and received $6,396,984 in dividends from Atmos Energy common stock during 2024. All other transactions which may be considered party-in-interest transactions relate to normal plan management and administrative services and the related payment of fees.
     
    At December 31, 2024 and 2023, the percentage of the Plan’s investments held in the Company’s common stock was 23.1% and 24.0%.
    6. Income Tax Status
    The Plan has received a determination letter from the IRS dated August 20, 2014 stating that the Plan is qualified under Section 401(a) of the Code; therefore, the related trust is exempt from taxation. Subsequent to this determination by the IRS, 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, as amended, is qualified and the related trust is tax-exempt.
    7. Risks and Uncertainties
    The Plan invests in various investment securities. Investment securities are exposed to various risks such as interest rate, market and credit risks. 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 Participant account balances and the amounts reported in the Statements of Net Assets Available for Benefits and the Statement of Changes in Net Assets Available for Benefits.
