    ATMOS ENERGY CORPORATION
    NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
    (Unaudited)
    March 31, 2025
    1.    Nature of Business
    Atmos Energy Corporation (“Atmos Energy” or the “Company”) and its subsidiaries are engaged in the regulated natural gas distribution and pipeline and storage businesses. Our distribution business is subject to federal and state regulation and/or regulation by local authorities in each of the states in which our regulated divisions and subsidiaries operate.
    Our distribution business delivers natural gas through sales and transportation arrangements to over 3.3 million residential, commercial, public authority, and industrial customers through our six regulated distribution divisions, which at March 31, 2025, covered service areas located in eight states.
    Our pipeline and storage business, which is also subject to federal and state regulations, includes the transportation of natural gas to our Texas and Louisiana distribution systems and the management of our underground storage facilities used to support our distribution business in various states.
        
    2.    Summary of Significant Accounting Policies
    Basis of Presentation
    These consolidated interim-period financial statements have been prepared in accordance with accounting principles generally accepted in the United States on the same basis as those used for the Company’s audited consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended September 30, 2024. In the opinion of management, all material adjustments (consisting of normal recurring accruals) necessary for a fair presentation have been made to the unaudited consolidated interim-period financial statements. These consolidated interim-period financial statements are condensed as permitted by the instructions to Form 10-Q and should be read in conjunction with the audited consolidated financial statements of Atmos Energy Corporation included in our Annual Report on Form 10-K for the fiscal year ended September 30, 2024. Because of seasonal and other factors, the results of operations for the six-month period ended March 31, 2025 are not indicative of our results of operations for the full 2025 fiscal year, which ends September 30, 2025.
    Significant accounting policies
    Our accounting policies are described in Note 2 to the consolidated financial statements in our Annual Report on Form 10-K for the fiscal year ended September 30, 2024.
    During the second quarter of fiscal 2025, we completed our annual goodwill impairment assessment using a qualitative assessment, as permitted under U.S. GAAP. We test for goodwill at the reporting unit level on an annual basis and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of the reporting unit. Based on the assessment performed, we determined that our goodwill was not impaired.
    No events have occurred subsequent to the balance sheet date that would require recognition or disclosure in the condensed consolidated financial statements.
    Recently issued accounting pronouncements
    In November 2023, the Financial Accounting Standards Board (FASB) issued guidance which provides updates to qualitative and quantitative reportable segment disclosure requirements, including enhanced disclosures about significant segment expenses and increased interim disclosure requirements, among others. The amendment is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted, and the amendments should be applied retrospectively. This amendment will be effective for our Form 10-K for fiscal 2025 and our Form 10-Q for the first quarter of fiscal 2026. We are currently evaluating the impact this may have on our financial statement disclosures.
    In December 2023, the FASB issued guidance which provides qualitative and quantitative updates to the rate reconciliation and income taxes paid disclosures, among others, in order to enhance the transparency of income tax disclosures, including consistent categories and greater disaggregation of information in the rate reconciliation and disaggregation by jurisdiction of income taxes paid. The amendment is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The amendments should be applied prospectively; however, retrospective application is also permitted. This amendment will be effective for our Form 10-K for fiscal 2026. We are currently evaluating the impact this amendment may have on our financial statement disclosures.
    7


    In November 2024, the FASB issued guidance that will require more detailed information about the types of expenses in commonly presented expense captions. The amendment is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. This amendment will be effective for our Form 10-K for fiscal 2028 and our Form 10-Q for the first quarter of fiscal 2029. We are currently evaluating the impact this may have on our financial statement disclosures.

        
    3.    Regulation
    Accounting principles generally accepted in the United States require cost-based, rate-regulated entities that meet certain criteria to reflect the authorized recovery of costs due to regulatory decisions in their financial statements. As a result, certain costs are permitted to be capitalized rather than expensed because they can be recovered through rates. We record certain costs as regulatory assets when future recovery through customer rates is considered probable. Regulatory liabilities are recorded when it is probable that revenues will be reduced for amounts that will be credited to customers through the ratemaking process. Substantially all of our regulatory assets are recorded as a component of other current assets and deferred charges and other assets and our regulatory liabilities are recorded as a component of other current liabilities and deferred credits and other liabilities. Deferred gas costs are recorded either in other current assets or liabilities.
    Regulatory assets and liabilities as of March 31, 2025 and September 30, 2024 included the following:
    March 31,

    Other51,006 34,338 
    $1,275,303 $1,227,882 
     
    (1)Infrastructure mechanisms in Texas, Louisiana, and Tennessee allow for the deferral of all eligible expenses associated with capital expenditures incurred pursuant to these rules, including the recording of interest on deferred expenses until the next rate proceeding (rate case or annual rate filing), at which time investment and costs would be recoverable through base rates.
    (2)Regulatory excess deferred taxes represent changes in our net deferred tax liability related to our cost of service ratemaking due to the enactment of Tax Cuts and Jobs Act of 2017 (the "TCJA"), a Kansas legislative change enacted in fiscal 2020, and a Louisiana legislative change enacted in fiscal 2025. See Note 12 to the condensed consolidated financial statements for further information.
    (3)In APT's general rate case settlement in December 2023, the RRC approved a new annual compliance filing that allows APT to recover certain system safety and integrity costs incurred each year. Costs above a specified benchmark are deferred onto the balance sheet as incurred. Once the filing is approved by the RRC, the revenue and expense are recognized over 12 months resulting in no impact to operating income.
    We deferred $32.4 million in carrying costs incurred after September 1, 2022 associated with interim financing for gas costs incurred in February 2021 during Winter Storm Uri. During fiscal 2024, we recovered $22.0 million of this amount. During the first six months of fiscal 2025, we have recovered $3.6 million of this amount. Of the remaining $6.8 million,
    8


    $0.4 million has been recorded as a current asset in other current assets as of March 31, 2025 and $6.4 million has been recorded as a long-term asset in deferred charges and other assets as of March 31, 2025 as we anticipate recovering this amount in future regulatory proceedings.

    4.    Segment Information

    We manage and review our consolidated operations through the following reportable segments:

    •The distribution segment is comprised of our regulated natural gas distribution and related sales operations in eight states.
    •The pipeline and storage segment is comprised primarily of the regulated pipeline and storage operations of our Atmos Pipeline-Texas division and our natural gas transmission operations in Louisiana.
    The accounting policies of the segments are the same as those described in the summary of significant accounting policies found in our Annual Report on Form 10-K for the fiscal year ended September 30, 2024.
    Income statements and capital expenditures for the three and six months ended March 31, 2025 and 2024 by segment are presented in the following tables:

    5.    Earnings Per Share
    We use the two-class method of computing earnings per share because we have participating securities in the form of non-vested restricted stock units with a nonforfeitable right to dividend equivalents, for which vesting is predicated solely on the passage of time. The calculation of earnings per share using the two-class method excludes income attributable to these participating securities from the numerator and excludes the dilutive impact of those shares from the denominator. Basic weighted average shares outstanding is calculated based upon the weighted average number of common shares outstanding during the periods presented. Also, this calculation includes fully vested stock awards that have not yet been issued as common stock. Additionally, the weighted average shares outstanding for diluted EPS includes the incremental effects of the forward sale agreements, discussed in Note 8 to the condensed consolidated financial statements, when the impact is dilutive.
    11


    Basic and diluted earnings per share for the three and six months ended March 31, 2025 and 2024 are calculated as follows:

    We have alternative revenue programs in each of our segments. In our distribution segment, we have weather-normalization adjustment mechanisms that serve to mitigate the effects of weather on our revenue. In our pipeline and storage segment, APT has a regulatory mechanism that requires that we share with its tariffed customers 75% of the difference between the total non-tariffed revenues earned during a test period and a revenue benchmark established by the RRC. Other revenues includes AEK revenues (see Note 9 to the condensed consolidated financial statements) and other miscellaneous revenues.
    Accounts receivable and allowance for uncollectible accounts
    Accounts receivable arise from natural gas sales to residential, commercial, industrial, public authority, and other customers. Our accounts receivable balance includes unbilled amounts which represent a customer’s consumption of gas from the date of the last cycle billing through the last day of the month. Our policy related to the accounting for our accounts receivable and allowance for uncollectible accounts is fully described in Note 2 to the consolidated financial statements in our Annual Report on Form 10-K for the fiscal year ended September 30, 2024. During the six months ended March 31, 2025, there were no material changes to this policy. Rollforwards of our allowance for uncollectible accounts for the three and six months ended March 31, 2025 and 2024 are presented in the table below. The allowance excludes the gas cost portion of customers’ bills for approximately 89 percent of our customers as we have the ability to collect these gas costs through our gas cost recovery mechanisms in most of our jurisdictions.
    In December 2023, the Mississippi Public Service Commission approved the recovery of uncollectible accounts through our purchased gas cost mechanism over a two-year period rather than through our annual filing mechanism over a one-year period. As a result of this decision, we recorded a $13.9 million reduction to bad debt expense during the first quarter of fiscal 2024. Of this amount, $9.7 million represents future recovery of customer receivables previously written off since April 2022 but not yet recovered through our rates. This amount increased our deferred gas cost regulatory asset. The remaining $4.2 million reduction represents a reversal of our allowance for uncollectible accounts for customer balances that have not yet been written off.

    7.    Debt
    The nature and terms of our debt instruments and credit facilities are described in detail in Note 8 to the consolidated financial statements in our Annual Report on Form 10-K for the fiscal year ended September 30, 2024. Other than as described below, there were no material changes in the terms of our debt instruments during the six months ended March 31, 2025.
    Long-term debt at March 31, 2025 and September 30, 2024 consisted of the following:

    On October 1, 2024, we completed a public offering of $650 million of 5.00% senior notes due December 2054, with an effective interest rate of 3.90%, after giving effect to the offering costs and settlement of our interest rate swaps. The net proceeds from the offering, after the underwriting discount and offering expenses, of $639.4 million were used for general corporate purposes.
    Short-term debt
    We utilize short-term debt to provide cost-effective, short-term financing until it can be replaced with a balance of long-term debt and equity financing that achieves the Company’s desired capital structure. Our short-term borrowing requirements are driven primarily by construction work in progress and the seasonal nature of the natural gas business.
    Our short-term borrowing requirements are satisfied through a combination of a $1.5 billion commercial paper program and four committed revolving credit facilities with third-party lenders that provide $3.1 billion of total working capital funding.
    Our commercial paper program is supported by a five-year unsecured $1.5 billion credit facility. On March 31, 2025, we elected to extend the maturity date from March 28, 2029 to March 28, 2030. This facility bears interest at a base rate or at a Term SOFR-based rate for the applicable interest period, plus a margin ranging from zero percent to 0.25 percent for base rate advances or a margin ranging from 0.75 percent to 1.25 percent for Term SOFR-based advances, based on the Company’s credit ratings. Additionally, the facility contains a $250 million accordion feature, which provides the opportunity to increase the total committed loan to $1.75 billion. At March 31, 2025 and September 30, 2024, there were no amounts outstanding under our commercial paper program.

    We also have a $1.5 billion three-year unsecured revolving credit facility that is used to provide additional working capital funding. On March 31, 2025, we elected to extend the maturity date from March 28, 2027 to March 28, 2028. This facility bears interest at a base rate or at a Term SOFR-based rate for the applicable interest period, plus a margin ranging from zero percent to 0.25 percent for base rate advances or a margin ranging from 0.75 percent to 1.25 percent for Term SOFR-based advances, based on the Company's credit ratings. Additionally, the facility contains a $250 million accordion feature, which provides the opportunity to increase the total committed loan to $1.75 billion. At March 31, 2025 and September 30, 2024, there were no borrowings outstanding under this facility.
    Additionally, we have a $50 million 364-day unsecured facility, which was renewed April 1, 2025 and is used to provide working capital funding. There were no borrowings outstanding under this facility as of March 31, 2025 and September 30, 2024.
    Finally, we have a $50 million 364-day unsecured revolving credit facility, which was renewed March 31, 2025 and is used to issue letters of credit and to provide working capital funding. At March 31, 2025, there were no borrowings outstanding under this facility; however, outstanding letters of credit reduced the total amount available to us to $44.4 million.
    Debt covenants
    The availability of funds under these credit facilities is subject to conditions specified in the respective credit agreements, all of which we currently satisfy. These conditions include our compliance with financial covenants and the continued accuracy of representations and warranties contained in these agreements. We are required by the financial covenants in each of these facilities to maintain, at the end of each fiscal quarter, a ratio of total-debt-to-total-capitalization of no greater than 70 percent. At March 31, 2025, our total-debt-to-total-capitalization ratio, as defined in the agreements, was 40 percent. In addition, both the interest margin and the fee that we pay on unused amounts under certain of these facilities are subject to adjustment depending upon our credit ratings.
    These credit facilities and our public indentures contain usual and customary covenants for our business, including covenants substantially limiting liens, substantial asset sales, and mergers. Additionally, our public debt indentures relating to our senior notes and debentures, as well as certain of our revolving credit agreements, each contain a default provision that is triggered if outstanding indebtedness arising out of any other credit agreements in amounts ranging from in excess of $15 million to in excess of $100 million becomes due by acceleration or if not paid at maturity. We were in compliance with all of our debt covenants as of March 31, 2025. If we were unable to comply with our debt covenants, we would likely be required to repay our outstanding balances on demand, provide additional collateral or take other corrective actions.

    Shelf Registration, At-the-Market Equity Sales Program and Equity Issuances
    On December 3, 2024, we filed a shelf registration statement with the Securities and Exchange Commission (SEC) that allows us to issue up to $8.0 billion in common stock and/or debt securities, which expires December 3, 2027. At March 31, 2025, $6.3 billion of securities were available for issuance under this shelf registration statement.
    17


    On December 3, 2024, we filed a prospectus supplement under the shelf registration statement relating to an at-the-market (ATM) equity sales program under which we may issue and sell shares of our common stock up to an aggregate offering price of $1.7 billion through December 3, 2027 (including shares of common stock that may be sold pursuant to forward sale agreements entered into concurrently with the ATM equity sales program). This ATM equity sales program replaced our previous ATM equity sales program, filed on May 8, 2024.
    During the six months ended March 31, 2025, we executed forward sales under our ATM equity sales program with various forward sellers who borrowed and sold 4,609,043 shares of our common stock at an aggregate price of $658.2 million. During the six months ended March 31, 2025, we also settled forward sale agreements with respect to 3,300,904 shares that had been borrowed and sold by various forward sellers under the ATM program for net proceeds of $379.5 million. As of March 31, 2025, $1.0 billion of equity was available for issuance under our existing ATM program. Additionally, we had $1.7 billion in available proceeds from outstanding forward sale agreements, as detailed below.

    9.    Securitization
    Kansas
    Atmos Energy Kansas Securitization I, LLC (AEK), a special-purpose entity wholly owned by Atmos Energy, was formed for the purpose of issuing securitized bonds to recover extraordinary costs incurred during Winter Storm Uri in February 2021. In June 2023, AEK completed a public offering of $95 million of Securitized Utility Tariff Bonds. AEK's assets cannot be used to settle Atmos Energy's obligations, and the holders of the Securitized Utility Tariff Bonds have no recourse against Atmos Energy.
    As described in Note 10 of our Annual Report on Form 10-K for the fiscal year ended September 30, 2024, AEK is considered to be a variable interest entity. As a result, AEK is included in the condensed consolidated financial statements of Atmos Energy.
    The following table summarizes the impact of AEK on our condensed consolidated balance sheets, for the periods indicated:

The fair value of the securitized long-term debt is determined using third party market value quotations, which are considered Level 2 fair value measurements for debt instruments where fair value is determined using the most recent available quoted market price. The carrying value and fair value of the securitized long-term debt as of March 31, 2025 was $81.0 million and $81.9 million, and as of September 30, 2024 was $85.1 million and $87.8 million.
    Texas
    In March 2023, the Texas Natural Gas Securitization Finance Corporation (the Finance Corporation), with the authority of the Texas Public Finance Authority (TPFA), issued $3.5 billion in customer rate relief bonds with varying scheduled final maturities from 12 to 18 years. The bonds are obligations of the Finance Corporation, payable from the customer rate relief charges and other bond collateral, and are not an obligation of Atmos Energy. We began collecting the customer rate relief charges on October 1, 2023, and any such property collected is solely owned by the Finance Corporation and not available to pay creditors of Atmos Energy.

    10.     Interim Pension and Other Postretirement Benefit Plan Information
    The components of our net periodic pension cost for our pension and other postretirement benefit plans for the three and six months ended March 31, 2025 and 2024 are presented in the following tables. Most of these costs are recoverable through our tariff rates. A portion of these costs is capitalized into our rate base or deferred as a regulatory asset or liability. The remaining costs are recorded as a component of operation and maintenance expense or other non-operating expense.

    11.    Commitments and Contingencies
    Litigation and Environmental Matters
    In the normal course of business, we are subject to various legal and regulatory proceedings. For such matters, we record liabilities when they are considered probable and estimable, based on currently available facts, our historical experience and our estimates of the ultimate outcome or resolution of the liability in the future. While the outcome of these proceedings is uncertain and a loss in excess of the amount we have accrued is possible though not reasonably estimable, it is the opinion of management that any amounts exceeding the accruals will not have a material adverse impact on our financial position, results of operations or cash flows.
    The National Transportation Safety Board (NTSB) issued a Preliminary Report on February 14, 2024 relating to its investigation of two incidents that occurred in Jackson, Mississippi on January 24 and 27, 2024 that resulted in one fatality. Atmos Energy is working closely with the NTSB and other state and federal regulators to help determine causal factors.
    The NTSB issued a Preliminary Report on December 30, 2024 relating to its investigation of an incident that occurred in Avondale, Louisiana on December 2, 2024 that resulted in one fatality. Atmos Energy is working closely with the NTSB and other state and federal regulators to help determine causal factors.
    We are a party to various other litigation and environmental-related matters or claims that have arisen in the ordinary course of our business. While the results of such litigation and response actions to such environmental-related matters or claims cannot be predicted with certainty, we continue to believe the final outcome of such litigation and matters or claims will not have a material adverse effect on our financial condition, results of operations, or cash flows.
    Purchase Commitments
    Our distribution divisions maintain supply contracts with several vendors that generally cover a period of up to one year. Commitments for estimated base gas volumes are established under these contracts on a monthly basis at contractually negotiated prices. Commitments for incremental daily purchases are made as necessary during the month in accordance with the terms of the individual contract.
    20


    Our Mid-Tex Division also maintains a limited number of long-term supply contracts to ensure a reliable source of gas for our customers in its service area, which obligate it to purchase specified volumes at prices under contracts indexed to natural gas hubs or fixed price contracts. These purchase commitment contracts are detailed in our Annual Report on Form 10-K for the fiscal year ended September 30, 2024. At March 31, 2025, we were committed to purchase 67.5 Bcf within one year and 57.5 Bcf within two to three years under indexed contracts. At March 31, 2025, we had no commitments under fixed price contracts.
    Rate Regulatory Proceedings
    As of March 31, 2025, routine rate regulatory proceedings were in progress in several of our service areas, which are discussed in further detail below in Management’s Discussion and Analysis — Recent Ratemaking Developments. Except for these proceedings, there were no material changes to rate regulatory proceedings for the six months ended March 31, 2025.

    12.    Income Taxes
    Income Tax Expense
    Our interim effective tax rates reflect the estimated annual effective tax rates for the fiscal years ended September 30, 2025 and 2024, adjusted for tax expense associated with certain discrete items. The effective tax rates for the three months ended March 31, 2025 and 2024 were 19.5% and 15.7% and for the six months ended March 31, 2025 and 2024 were 19.0% and 15.3%. These effective tax rates differ from the federal statutory tax rate of 21% primarily due to the amortization of excess deferred federal income tax liabilities, tax credits, state income taxes, and other permanent book-to-tax differences. These adjustments have a relative impact on the effective tax rate proportionally to pretax income or loss.
    Regulatory Excess Deferred Taxes
    Regulatory excess net deferred taxes represent changes in our net deferred tax liability related to our cost of service ratemaking due to the enactment of the Tax Cuts and Jobs Act of 2017 (the TCJA), a Kansas legislative change enacted in fiscal 2020, and a Louisiana legislative change enacted in fiscal 2025. Currently, the regulatory excess net deferred tax liability of $178.6 million is being returned over various periods. Of this amount, $115.5 million is being returned to customers over 12 - 60 months. An additional $48.6 million is being returned to customers on a provisional basis over 15 - 68 years until our regulators establish the final refund periods. The refund of the remaining $14.5 million will be addressed in future rate proceedings.
    As of March 31, 2025 and September 30, 2024, $73.9 million and $79.7 million is recorded in other current liabilities.

    13.    Financial Instruments
    We currently use financial instruments to mitigate commodity price risk and interest rate risk. The objectives and strategies for using financial instruments and the related accounting for these financial instruments are fully described in Notes 2 and 16 to the consolidated financial statements in our Annual Report on Form 10-K for the fiscal year ended September 30, 2024. During the six months ended March 31, 2025, there were no material changes in our objectives, strategies, and accounting for using financial instruments. Our financial instruments do not contain any credit-risk-related or other contingent features that could cause payments to be accelerated when our financial instruments are in net liability positions. The following summarizes those objectives and strategies.
    Commodity Risk Management Activities
    Our purchased gas cost adjustment mechanisms essentially insulate our distribution segment from commodity price risk; however, our customers are exposed to the effects of volatile natural gas prices. We manage this exposure through a combination of physical storage, fixed-price forward contracts, and financial instruments, primarily over-the-counter swap and option contracts, in an effort to minimize the impact of natural gas price volatility on our customers during the winter heating season.
    We typically seek to hedge between 25 and 50 percent of anticipated heating season gas purchases using financial instruments. For the 2024-2025 heating season (generally October through March), in the jurisdictions where we are permitted to utilize financial instruments, we hedged approximately 24.0 Bcf of the winter flowing gas requirements. We have not designated these financial instruments as hedges for accounting purposes.
    Interest Rate Risk Management Activities
    We manage interest rate risk by periodically entering into financial instruments to effectively fix the Treasury yield component of the interest cost associated with anticipated financings.

    The following tables present detailed information concerning the impact of financial instruments on our condensed consolidated balance sheet and statements of comprehensive income.
    As of March 31, 2025, our financial instruments were comprised of both long and short commodity positions. A long position is a contract to purchase the commodity, while a short position is a contract to sell the commodity. As of March 31, 2025, we had 4,017 MMcf of net long commodity contracts outstanding. These contracts have not been designated as hedges.
    Financial Instruments on the Balance Sheet
    The following tables present the fair value and balance sheet classification of our financial instruments as of March 31, 2025 and September 30, 2024. The gross amounts of recognized assets and liabilities are netted within our condensed consolidated balance sheets to the extent that we have netting arrangements with our counterparties. However, as of March 31, 2025 and September 30, 2024, no gross amounts and no cash collateral were netted within our consolidated balance sheet.

    Impact of Financial Instruments on the Statement of Comprehensive Income
    Cash Flow Hedges
    As discussed above, our distribution segment has interest rate agreements, which we designated as cash flow hedges at the time the agreements were executed. The net (gain) loss on settled interest rate agreements reclassified from AOCI into interest charges on our condensed consolidated statements of comprehensive income for the three months ended March 31, 2025 and 2024 was $(5.1) million and $(3.2) million and for the six months ended March 31, 2025 and 2024 was $(10.2) million and $(6.4) million.
    The following table summarizes the gains and losses arising from hedging transactions that were recognized as a component of other comprehensive income (loss), net of taxes, for the three and six months ended March 31, 2025 and 2024.

    Deferred gains (losses) recorded in AOCI associated with our interest rate agreements are recognized in earnings as they are amortized over the terms of the underlying debt instruments. As of March 31, 2025, we had $387.0 million of net realized gains in AOCI associated with our interest rate agreements. The following amounts, net of deferred taxes, represent the expected recognition in earnings of the deferred net gains recorded in AOCI associated with our interest rate agreements, based upon the fair values of these agreements at the date of settlement. The remaining amortization periods for these settled amounts extend through fiscal 2055. However, the table below does not include the expected recognition in earnings of our outstanding interest rate swaps as those instruments have not yet settled.

    Total$387,005 

    Financial Instruments Not Designated as Hedges
    As discussed above, commodity contracts which are used in our distribution segment are not designated as hedges. However, there is no earnings impact on our distribution segment as a result of the use of these financial instruments because the gains and losses arising from the use of these financial instruments are recognized in the consolidated statement of comprehensive income as a component of purchased gas cost when the related costs are recovered through our rates and recognized in revenue. Accordingly, the impact of these financial instruments is excluded from this presentation.

    14.    Fair Value Measurements
    We report certain assets and liabilities at fair value, which is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). We record cash and cash equivalents, restricted cash and cash equivalents, accounts receivable, accounts payable, and short-term debt at carrying value, which substantially approximates fair value due to the short-term nature of these assets and liabilities. For other financial assets and liabilities, we primarily use quoted market prices and other observable market pricing information to minimize the use of unobservable pricing inputs in our measurements when determining fair value. The methods used to determine fair value for our assets and liabilities are fully described in Note 2 to the consolidated financial statements in our Annual Report on Form 10-K for the fiscal year ended September 30, 2024. During the six months ended March 31, 2025, there were no changes in these methods.
    23


    Fair value measurements also apply to the valuation of our pension and postretirement plan assets. Current accounting guidance requires employers to annually disclose information about fair value measurements of the assets of a defined benefit pension or other postretirement plan. The fair value of these assets is presented in Note 11 to the consolidated financial statements in our Annual Report on Form 10-K for the fiscal year ended September 30, 2024.
    Quantitative Disclosures
    Financial Instruments
    The classification of our fair value measurements requires judgment regarding the degree to which market data is observable or corroborated by observable market data. 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), with the lowest priority given to unobservable inputs (Level 3). The following tables summarize, by level within the fair value hierarchy, our assets and liabilities that were accounted for at fair value on a recurring basis as of March 31, 2025 and September 30, 2024. Assets and liabilities are categorized in their entirety based on the lowest level of input that is significant to the fair value measurement.

    Debt and equity securities are comprised of our available-for-sale debt securities and our equity securities. As described in Note 2 to the consolidated financial statements in our Annual Report on Form 10-K for the fiscal year ended September 30, 2024, we evaluate the performance of our available-for-sale debt securities on an investment by investment basis for impairment, taking into consideration the investment’s purpose, volatility, current returns, and any intent to sell the security. As of March 31, 2025, no allowance for credit losses was recorded for our available-for-sale debt securities. At March 31, 2025 and September 30, 2024, the amortized cost of our available-for-sale debt securities was $36.9 million and $38.9 million. At March 31, 2025, we maintained investments in bonds that have contractual maturity dates ranging from April 2025 through January 2028.
    Other Fair Value Measures
    Our long-term debt is recorded at carrying value. The fair value of our long-term debt, excluding finance leases, is determined using third party market value quotations, which are considered Level 1 fair value measurements for debt instruments with a recent, observable trade or Level 2 fair value measurements for debt instruments where fair value is determined using the most recent available quoted market price. The carrying value of our finance leases materially approximates fair value. The following table presents the carrying value and fair value of our long-term debt, excluding finance leases, debt issuance costs and original issue premium or discount, as of March 31, 2025 and September 30, 2024:

    Information regarding our concentration of credit risk is disclosed in Note 18 to the consolidated financial statements in our Annual Report on Form 10-K for the fiscal year ended September 30, 2024. During the six months ended March 31, 2025, there were no material changes in our concentration of credit risk.

    REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
    The Board of Directors and Shareholders of Atmos Energy Corporation

    Results of Review of Interim Financial Statements
    We have reviewed the accompanying condensed consolidated balance sheet of Atmos Energy Corporation (the Company) as of March 31, 2025, the related condensed consolidated statements of comprehensive income for the three and six month periods ended March 31, 2025 and 2024, the condensed consolidated statement of cash flows for the six month periods ended March 31, 2025 and 2024, and the related notes (collectively referred to as the "condensed consolidated interim financial statements"). Based on our reviews, we are not aware of any material modifications that should be made to the condensed consolidated interim financial statements for them to be in conformity with U.S. generally accepted accounting principles.
    We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheet of the Company as of September 30, 2024, the related consolidated statements of comprehensive income, shareholders’ equity and cash flows for the year then ended, and the related notes (not presented herein); and in our report dated November 18, 2024, we expressed an unqualified audit opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated balance sheet as of September 30, 2024, is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.
    Basis for Review Results
    These financial statements are the responsibility of the Company's management. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the SEC and the PCAOB. We conducted our review in accordance with the standards of the PCAOB. A review of interim financial statements consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the PCAOB, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

    Item 2.Management’s Discussion and Analysis of Financial Condition and Results of Operations

    INTRODUCTION
    The following discussion should be read in conjunction with the condensed consolidated financial statements in this Quarterly Report on Form 10-Q and Management’s Discussion and Analysis in our Annual Report on Form 10-K for the year ended September 30, 2024.
    Cautionary Statement for the Purposes of the Safe Harbor under the Private Securities Litigation Reform Act of 1995
    The statements contained in this Quarterly Report on Form 10-Q may contain “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. All statements other than statements of historical fact included in this Report are forward-looking statements made in good faith by us and are intended to qualify for the safe harbor from liability established by the Private Securities Litigation Reform Act of 1995. When used in this Report, or any other of our documents or oral presentations, the words “anticipate”, “believe”, “estimate”, “expect”, “forecast”, “goal”, “intend”, “objective”, “plan”, “projection”, “seek”, “strategy”, or similar words are intended to identify forward-looking statements. Such forward-looking statements are subject to risks and uncertainties that could cause actual results to differ materially from those expressed or implied in the statements relating to our strategy, operations, markets, services, rates, recovery of costs, availability of gas supply, and other factors. These risks and uncertainties include the following: federal, state, and local regulatory and political trends and decisions, including the impact of rate proceedings before various state regulatory commissions; increased federal regulatory oversight and potential penalties; possible increased federal, state, and local regulation of the safety of our operations; possible significant costs and liabilities resulting from pipeline integrity and other similar programs and related repairs; the inherent hazards and risks involved in distributing, transporting, and storing natural gas; the availability and accessibility of contracted gas supplies, interstate pipeline, and/or storage services; increased competition from energy suppliers and alternative forms of energy; failure to attract and retain a qualified workforce; natural disasters, adverse weather, terrorist activities, or other events and other risks and uncertainties discussed herein, all of which are difficult to predict and many of which are beyond our control; failure of technology that affects the Company's business operations; the threat of cyber-attacks or acts of cyber-terrorism that could disrupt our business operations and information technology systems or result in the loss or exposure of confidential or sensitive customer, employee, or Company information; the impact of new cybersecurity compliance requirements; adverse weather conditions; the impact of legislation to reduce or eliminate greenhouse gas emissions or fossil fuels; the impact of climate change; the capital-intensive nature of our business; our ability to continue to access the credit and capital markets to execute our business strategy; market risks beyond our control affecting our risk management activities, including commodity price volatility, counterparty performance or creditworthiness, and interest rate risk; the concentration of our operations in Texas; the impact of adverse economic conditions on our customers; changes in the availability and price of natural gas; and increased costs of providing health care benefits, along with pension and postretirement health care benefits and increased funding requirements. Accordingly, while we believe these forward-looking statements to be reasonable, there can be no assurance that they will approximate actual experience or that the expectations derived from them will be realized.

    OVERVIEW
    Atmos Energy and our subsidiaries are engaged in the regulated natural gas distribution and pipeline and storage businesses. We distribute natural gas through sales and transportation arrangements to over 3.3 million residential, commercial, public authority, and industrial customers throughout our six distribution divisions, which at March 31, 2025 covered service areas located in eight states. In addition, we transport natural gas for others through our distribution and pipeline systems.

    We manage and review our consolidated operations through the following reportable segments:

    •The distribution segment is comprised of our regulated natural gas distribution and related sales operations in eight states.
    •The pipeline and storage segment is comprised primarily of the regulated pipeline and storage operations of our Atmos Pipeline-Texas division and our natural gas transmission operations in Louisiana.

    27


    Our vision is to be the safest provider of natural gas services. Our commitment to this vision requires significant levels of capital spending to modernize our natural gas distribution system and operating costs to deliver natural gas safely and reliably and in full compliance with the various safety regulations impacting our business. We have the ability to begin recovering a significant portion of our expenditures timely through rate designs and mechanisms that reduce or eliminate regulatory lag and separate the recovery of our approved rate from customer usage patterns. The execution of our capital spending program, the ability to recover these expenditures timely, and our ability to access the capital markets to satisfy our financing needs are the primary drivers that affect our financial performance.
    We anticipate making significant capital expenditures for the foreseeable future to modernize our distribution and transmission system, to comply with the safety rules and regulations issued by the regulatory authorities responsible for the service areas in which we operate, and to prepare to serve the growing needs of the communities we serve. Between fiscal years 2025 and 2029, we anticipate spending approximately $24 billion, with more than 80 percent dedicated to safety and reliability spending. The magnitude and allocation of these expenditures may be affected by factors such as new policy and regulations, population growth, and increased labor and materials costs. Although we believe these costs are ultimately recoverable through our rates based on the regulatory frameworks currently available to us, full recovery is not assured.
    CRITICAL ACCOUNTING ESTIMATES AND POLICIES
    Our condensed consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States. Preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, and expenses and the related disclosures of contingent assets and liabilities. We based our estimates on historical experience and various other assumptions that we believe to be reasonable under the circumstances. On an ongoing basis, we evaluate our estimates, including those related to the allowance for doubtful accounts, legal and environmental accruals, insurance accruals, pension and postretirement obligations, deferred income taxes, and the valuation of goodwill and other long-lived assets. Actual results may differ from such estimates.
    Our critical accounting policies used in the preparation of our consolidated financial statements are described in our Annual Report on Form 10-K for the fiscal year ended September 30, 2024 and include the following:
    •Regulation
    •Pension and other postretirement plans
    Our critical accounting policies are reviewed periodically by the Audit Committee of our Board of Directors. There were no significant changes to these critical accounting policies during the six months ended March 31, 2025.
    RESULTS OF OPERATIONS
    Executive Summary
    During the six months ended March 31, 2025, we recorded net income of $837.4 million, or $5.26 per diluted share, compared to net income of $743.3 million, or $4.93 per diluted share for the six months ended March 31, 2024.
    The 13 percent year-over-year increase in net income largely reflects positive rate outcomes driven by safety and reliability spending, partially offset by higher bad debt expense, depreciation and property tax expenses, and higher spending on certain operating expenses.
    During the six months ended March 31, 2025, we implemented, or received approval to implement, ratemaking regulatory actions which resulted in an increase in annual operating income of $152.6 million. Additionally, as of March 31, 2025, we had ratemaking efforts in progress seeking a total increase in annual operating income of $224.7 million.
    Capital expenditures for the six months ended March 31, 2025 were $1,730.9 million. Approximately 85 percent was invested to improve the safety and reliability of our distribution and transportation systems, with a significant portion of this investment incurred under regulatory mechanisms that reduce lag to six months or less.
    During the six months ended March 31, 2025, we completed approximately $1.0 billion of long-term debt and equity financing. As of March 31, 2025, our equity capitalization was 60.9 percent. As of March 31, 2025, we had approximately $5.3 billion in total liquidity, consisting of $543.5 million in cash and cash equivalents, $1,659.6 million in funds available through equity forward sales agreements and $3,094.4 million in undrawn capacity under our credit facilities.
    The following discusses the results of operations for each of our operating segments.
    Distribution Segment
    The distribution segment is comprised of our regulated natural gas distribution and related sales operations in eight states. The primary factors that impact the results of this segment are our ability to earn our authorized rates of return, competitive factors in the energy industry, and economic conditions in our service areas.
    28


    Our ability to earn our authorized rates of return is based primarily on our ability to improve the rate design in our various ratemaking jurisdictions to minimize regulatory lag and, ultimately, separate the recovery of our approved rates from customer usage patterns. Improving rate design is a long-term process and is further complicated by the fact that we operate in multiple rate jurisdictions. Under our current rate design, approximately 70 percent of our distribution segment revenues are earned through the first six months of the fiscal year. Additionally, we currently recover approximately 50 percent of our distribution segment revenue, excluding gas costs, through the base customer charge, which partially separates the recovery of our approved rate from customer usage patterns.
    Seasonal weather patterns can also affect our distribution operations. However, the effect of weather that is above or below normal is substantially offset through weather normalization adjustments, known as WNA, which have been approved by state regulatory commissions for approximately 97 percent of our residential and commercial revenues in the following states for the following time periods:
    Kansas, West TexasOctober — May
    TennesseeOctober — April
    Kentucky, Mississippi, Mid-TexNovember — April
    LouisianaDecember — March
    VirginiaJanuary — December
    Our distribution operations are also affected by the cost of natural gas. We are generally able to pass the cost of gas through to our customers without markup under purchased gas cost adjustment mechanisms; therefore, increases in the cost of gas are offset by a corresponding increase in revenues. Revenues in our Texas and Mississippi service areas include franchise fees and gross receipts taxes, which are calculated as a percentage of revenue (inclusive of gas costs). Therefore, the amount of these taxes included in revenues is influenced by the cost of gas and the level of gas sales volumes. We record the associated tax expense as a component of taxes, other than income.
    The cost of gas typically does not have a direct impact on our operating income because these costs are recovered through our purchased gas cost adjustment mechanisms. However, higher gas costs may adversely impact our accounts receivable collections, resulting in higher bad debt expense. This risk is currently mitigated by rate design that allows us to collect from our customers the gas cost portion of our bad debt expense on approximately 89 percent of our residential and commercial revenues. Additionally, higher gas costs may require us to increase borrowings under our credit facilities, resulting in higher interest expense. Finally, higher gas costs, as well as competitive factors in the industry and general economic conditions may cause customers to conserve or, in the case of industrial consumers, to use alternative energy sources.

    Operating income for our distribution segment increased 13.5 percent. Key drivers for the change in operating income include:
    •an $86.4 million increase in rate adjustments, primarily in our Mid-Tex Division.
    •an $8.3 million increase related to residential customer growth, primarily in our Mid-Tex Division, and increased industrial load.
    •an $18.6 million decrease in refunds of excess deferred taxes to customers, which is substantially offset in income tax expense.
    Partially offset by:
    •a $23.7 million increase in depreciation expense and property taxes associated with increased capital investments.
    •a $15.6 million increase in employee-related costs primarily due to an increase in headcount to support company growth.
    •a $6.2 million increase in system monitoring, line locating, and other compliance-related activities.

    Recent Ratemaking Developments
    The amounts described in the following sections represent the operating income that was requested or received in each rate filing, which may not necessarily reflect the stated amount referenced in the final order, as certain operating costs may have changed as a result of a commission’s or other governmental authority’s final ruling. During the first six months of fiscal 2025, we implemented, or received approval to implement, regulatory proceedings, resulting in a $152.6 million increase in annual operating income as summarized below. Our ratemaking outcomes include the refund (return) of excess deferred income taxes (EDIT) resulting from previously enacted tax reform legislation and do not reflect the true economic benefit of the outcomes because they do not include the corresponding income tax benefit. Excluding these amounts, our total rate outcomes for ratemaking activities for the six months ended March 31, 2025 were $153.3 million.

    Annual Formula Rate Mechanisms
    As an instrument to reduce regulatory lag, formula rate mechanisms allow us to refresh our rates on an annual basis without filing a formal rate case. However, these filings still involve discovery by the appropriate regulatory authorities prior to the final determination of rates under these mechanisms. We currently have formula rate mechanisms in our Louisiana, Mississippi, and Tennessee operations and in substantially all the service areas in our Texas divisions. Additionally, we have specific infrastructure programs in substantially all of our distribution divisions with tariffs in place to permit the investment associated with these programs to have their surcharge rate adjusted annually to recover approved capital costs incurred in a prior test-year period. The following table summarizes our annual formula rate mechanisms by state:

    Rate Case Filings
    A rate case is a formal request from Atmos Energy to a regulatory authority to increase rates that are charged to our customers. Rate cases may also be initiated when the regulatory authorities request us to justify our rates. This process is referred to as a “show cause” action. Adequate rates are intended to provide for recovery of the Company’s costs as well as a fair rate of return and ensure that we continue to deliver reliable, reasonably priced natural gas service safely to our customers. There was no rate case activity completed in our distribution segment during the six months ended March 31, 2025.

    Pipeline and Storage Segment
    Our pipeline and storage segment consists of the regulated pipeline and storage operations of our Atmos Pipeline–Texas Division (APT) and our natural gas transmission operations in Louisiana. APT is an intrastate pipeline in Texas with a heavy concentration in the established natural gas producing areas of central, northern, and eastern Texas, extending into or near the major producing areas of the Barnett Shale, the Texas Gulf Coast, and the Permian Basin of West Texas. APT provides transportation and storage services to our Mid-Tex Division, other third-party local distribution companies, industrial, and electric generation customers, as well as marketers and producers. Over 80 percent of this segment’s revenues are derived from these APT services. These revenues are subject to traditional ratemaking governed by the Texas Railroad Commission (RRC). As part of its pipeline operations, APT owns and operates five underground storage facilities in Texas.
    33


    Our natural gas transmission operations in Louisiana are comprised of a 21-mile pipeline located in the New Orleans, Louisiana area that is primarily used to aggregate gas supply for our distribution division in Louisiana under a long-term contract and, on a more limited basis, to third parties. The demand fee charged to our Louisiana distribution division for these services is subject to regulatory approval by the Louisiana Public Service Commission. We also manage two asset management plans, which have been approved by applicable state regulatory commissions. Generally, these asset management plans require us to share with our distribution customers a significant portion of the cost savings earned from these arrangements.
    Our pipeline and storage segment is impacted by seasonal weather patterns, competitive factors in the energy industry, and economic conditions in our Texas and Louisiana service areas. Natural gas prices do not directly impact the results of this segment as revenues are derived from the transportation and storage of natural gas. However, natural gas prices and demand for natural gas could influence the level of drilling activity in the supply areas that we serve, which may influence the level of throughput we may be able to transport on our pipelines. Further, natural gas price differences between the various hubs that we serve in Texas could influence the volumes of gas transported for shippers through our Texas pipeline system and rates for such transportation.
    The results of APT are also significantly impacted by the natural gas requirements of its local distribution company customers. Additionally, its operations may be impacted by the timing of when costs and expenses are incurred and when these costs and expenses are recovered through its tariffs.
    APT annually uses GRIP to recover capital costs incurred in the prior calendar year. On February 26, 2025, APT made a GRIP filing that covered changes in net property, plant and equipment investments from January 1, 2024 through December 31, 2024 with a requested increase in operating income of $77.2 million.
    The demand fee our Louisiana natural gas transmission pipeline charges to our Louisiana distribution division increases five percent annually and has been approved by the Louisiana Public Service Commission until September 30, 2027.

    Operating income for our pipeline and storage segment increased 16.4 percent. Key drivers for the change in operating income include:
    •a $25.4 million increase primarily due to rate adjustments from the GRIP filing approved in May 2024 and the System Safety and Integrity Rider filing approved in November 2024.
    •a $3.4 million increase in APT's through-system activities primarily associated with increased spreads.
    •a $4.1 million increase due to higher capacity contracted by tariff-based customers due to their increased peak day demand.

    Partially offset by:
    •a $7.9 million increase in depreciation expense and property taxes associated with increased capital investments.
    •a $4.7 million increase in expenses recognized as a result of the System Safety and Integrity Rider filing approved in November 2024, which is offset in operating revenues.

    Operating income for our pipeline and storage segment increased 18.6 percent. Key drivers for the change in operating income include:
    •a $48.2 million increase primarily due to rate adjustments from the GRIP filing approved in May 2024, the System Safety and Integrity Rider filing approved in November 2024, and the rate case approved in December 2023.
    •an $11.4 million increase in APT's through-system activities primarily associated with increased spreads.
    •a $9.1 million decrease in refunds of excess deferred taxes to customers, which is partially offset in income tax expense.
    •an $8.2 million increase due to higher capacity contracted by tariff-based customers due to their increased peak day demand.
    Partially offset by:
    •a $13.3 million increase in depreciation expense and property taxes associated with increased capital investments.
    •a $9.4 million increase in expenses recognized as a result of the System Safety and Integrity Rider filing approved in November 2024, which is offset in operating revenues.
    •a $5.6 million increase in expenses related to compliance-related activities.
    Liquidity and Capital Resources
    The liquidity required to fund our working capital, capital expenditures, and other cash needs is provided from a combination of internally generated cash flows and external debt and equity financing. Additionally, we have a $1.5 billion commercial paper program and four committed revolving credit facilities with $3.1 billion in total availability from third-party lenders. The commercial paper program and credit facilities provide cost-effective, short-term financing until it can be replaced with a balance of long-term debt and equity financing that achieves the Company's desired capital structure. Additionally, we have various uncommitted trade credit lines with our gas suppliers that we utilize to purchase natural gas on a monthly basis.

    On December 3, 2024, we filed a shelf registration statement with the Securities and Exchange Commission (SEC) that allows us to issue up to $8.0 billion in common stock and/or debt securities, which expires December 3, 2027. As of March 31, 2025, $6.3 billion of securities were available for issuance under this shelf registration statement.
    On December 3, 2024, we filed a prospectus supplement under the shelf registration statement relating to an at-the-market (ATM) equity sales program under which we may issue and sell shares of our common stock up to an aggregate offering price of $1.7 billion through December 3, 2027 (including shares of common stock that may be sold pursuant to forward sale agreements entered into in connection with the ATM equity sales program), which expires December 3, 2027. This ATM equity sales program replaced our previous ATM equity sales program, filed on May 8, 2024. As of March 31, 2025, $1.0 billion of equity was available for issuance under our existing ATM equity sales program. Additionally, as of March 31, 2025, we had $1.7 billion in available proceeds from outstanding forward sale agreements. Additional details are summarized in Note 8 to the condensed consolidated financial statements.
    The liquidity provided by these sources is expected to be sufficient to fund the Company's working capital needs and capital expenditure program for the remainder of fiscal year 2025. Additionally, we expect to continue to be able to obtain financing upon reasonable terms as necessary.

    Cash Flows
    Our internally generated funds may change in the future due to a number of factors, some of which we cannot control. These factors include regulatory changes, the price for our services, demand for such products and services, margin requirements resulting from significant changes in commodity prices, operational risks, and other factors.
    Cash flows from operating, investing, and financing activities for the six months ended March 31, 2025 and 2024 are presented below.

    Cash flows from operating activities
    For the six months ended March 31, 2025, we generated cash flow from operating activities of $1,205.0 million compared with $991.9 million for the six months ended March 31, 2024. Operating cash flow increased $213.1 million primarily due to the positive effects of successful rate case outcomes achieved in fiscal 2024.
    Cash flows from investing activities
    Our capital expenditures are primarily used to improve the safety and reliability of our distribution and transmission system through pipeline replacement and system modernization and to enhance and expand our system to meet customer needs. Over the last three fiscal years, approximately 86 percent of our capital spending has been committed to improving the safety and reliability of our system.
    For the six months ended March 31, 2025, cash used for investing activities was $1,717.5 million compared to $1,409.3 million for the six months ended March 31, 2024. Capital spending in our distribution segment increased $148.3 million, primarily as a result of increased system modernization and customer growth spending. Capital spending in our pipeline and storage segment increased $167.0 million primarily due to increased spending for pipeline system safety and reliability in Texas.
    Cash flows from financing activities
    For the six months ended March 31, 2025, our financing activities provided $748.8 million of cash compared with $661.9 million of cash provided by financing activities in the prior-year period.
    In the six months ended March 31, 2025, we received approximately $1.0 billion in net proceeds from the issuance of long-term debt and equity. We completed a public offering of $650 million of 5.00% senior notes due December 2054, and received net proceeds from the offering, after the underwriting discount and offering expenses, of $639.4 million. Additionally, during the six months ended March 31, 2025, we settled 3,300,904 shares that had been sold on a forward basis for net proceeds of $379.5 million. The net proceeds were used primarily to support capital spending and for other general corporate purposes. Cash dividends increased due to an 8.1 percent increase in our dividend rate and an increase in shares outstanding.
    In the six months ended March 31, 2024, we received approximately $1.2 billion in net proceeds from the issuance of long-term debt and equity. We completed a public offering of $500 million of 6.20% senior notes due November 2053 and $400 million of 5.90% senior notes due November 2033, and received net proceeds from the offering, after the underwriting discount and offering expenses, of $889.4 million. Additionally, during the six months ended March 31, 2024, we settled 2,144,558 shares that had been sold on a forward basis for net proceeds of $254.0 million. The net proceeds were used primarily to support capital spending and for other general corporate purposes. Cash dividends increased due to an 8.8 percent increase in our dividend rate and an increase in shares outstanding.

    Credit Ratings
    Our credit ratings directly affect our ability to obtain short-term and long-term financing, in addition to the cost of such financing. In determining our credit ratings, the rating agencies consider a number of quantitative factors, including but not limited to, debt to total capitalization, operating cash flow relative to outstanding debt, operating cash flow coverage of interest, and pension liabilities. In addition, the rating agencies consider qualitative factors such as consistency of our earnings over time, the quality of our management and business strategy, the risks associated with our businesses, and the regulatory structures that govern our rates in the states where we operate.
    Our debt is rated by two rating agencies: Standard & Poor’s Corporation (S&P) and Moody’s Investors Service (Moody’s). On April 2, 2025, Moody's reaffirmed its short-term credit rating, downgraded our long-term credit rating to A2,
    37


    and placed our ratings under stable outlook. Currently, our outlook and debt ratings, which are all considered investment grade, are as follows:
    S&P Moody’s
    Senior unsecured long-term debtA-  A2
    Short-term debtA-2  P-1
    OutlookStableStable
    A significant degradation in our operating performance or a significant reduction in our liquidity caused by more limited access to the private and public credit markets as a result of deteriorating global or national financial and credit conditions could trigger a negative change in our ratings outlook or even a reduction in our credit ratings by the two credit rating agencies. This would mean more limited access to the private and public credit markets and an increase in the costs of such borrowings.
    A credit rating is not a recommendation to buy, sell, or hold securities. The highest investment grade credit rating is AAA for S&P and Aaa for Moody’s. The lowest investment grade credit rating is BBB- for S&P and Baa3 for Moody’s. Our credit ratings may be revised or withdrawn at any time by the rating agencies, and each rating should be evaluated independently of any other rating. There can be no assurance that a rating will remain in effect for any given period of time or that a rating will not be lowered, or withdrawn entirely, by a rating agency if, in its judgment, circumstances so warrant.
    Debt Covenants
    We were in compliance with all of our debt covenants as of March 31, 2025. Our debt covenants are described in greater detail in Note 7 to the condensed consolidated financial statements.
    Contractual Obligations and Commercial Commitments
    Except as noted in Note 11 to the condensed consolidated financial statements, there were no significant changes in our contractual obligations and commercial commitments during the six months ended March 31, 2025.
    Risk Management Activities
    In our distribution and pipeline and storage segments, we use a combination of physical storage, fixed physical contracts, and fixed financial contracts to reduce our exposure to unusually large winter-period gas price increases. Additionally, we manage interest rate risk by periodically entering into financial instruments to effectively fix the Treasury yield component of the interest cost associated with anticipated financings.

During the six months ended March 31, 2025, there were no material changes in our quantitative and qualitative disclosures about market risk.

    Item 4.Controls and Procedures
    Management’s Evaluation of Disclosure Controls and Procedures
    We carried out an evaluation, under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, of the effectiveness of the Company’s disclosure controls and procedures, as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (Exchange Act). Based on this evaluation, the Company’s principal executive officer and principal financial officer have concluded that the Company’s disclosure controls and procedures were effective as of March 31, 2025 to provide reasonable assurance that information required to be disclosed by us, including our consolidated entities, in the reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified by the SEC’s rules and forms, including a reasonable level of assurance that such information is accumulated and communicated to our management, including our principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure.
    Changes in Internal Control over Financial Reporting
        
        We did not make any changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the second quarter of the fiscal year ended September 30, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
