Investing in the Series 2023-A Senior Secured Securitized Utility Tariff Bonds involves risks. Please read “RISK FACTORS” beginning on page 13 to read about factors you should consider before buying the securitized utility tariff bonds.

Atmos Energy Corporation (“Atmos Energy”), as “depositor”, is offering up to $95,000,000 aggregate principal amount of Series 2023-A Senior Secured Securitized Utility Tariff Bonds (the “securitized utility tariff bonds”) to be issued by Atmos Energy Kansas Securitization I, LLC, a Delaware limited liability company (the “issuing entity” or “us”) and wholly owned subsidiary of Atmos Energy. Atmos Energy is the “seller,” the “initial servicer” and the “sponsor” with regard to the securitized utility tariff bonds. The securitized utility tariff bonds are senior secured obligations of the issuing entity and will be secured by the securitized utility tariff property (the “securitized utility tariff property”) consisting of the right to impose and collect securitized utility tariff charges (the “securitized utility tariff charge”) paid by all existing and future retail customers within Atmos Energy’s service area in Kansas, as such service area exists on the date of the financing order, and as such service area may, at the discretion of Atmos Energy, be expanded or acquired as provided for in the financing order. Securitized utility tariff charges are required to be adjusted at least semi-annually, and more frequently as necessary, to correct any under-collection or over-collection of securitized utility tariff charges during the preceding six months and to ensure the projected recovery of amounts sufficient to provide all payments of debt service and other required amounts and charges in connection with the securitized utility tariff bonds. The primary forms of credit enhancement for the securitized utility tariff bonds will be provided by such statutory true-up mechanism, as well as by general, excess funds and capital subaccounts held under the Indenture governing the securitized utility tariff bonds.

Each securitized utility tariff bond will be entitled to interest on and of each year, beginning on , 2024. The first scheduled payment date is , 2024. Interest will accrue from the date of issuance and must be paid by the purchaser of the securitized utility tariff bonds if the securitized utility tariff bonds are delivered after that date. On each payment date, scheduled principal payments shall be paid sequentially in accordance with the expected sinking fund schedule in this prospectus, but only to the extent funds are available in the collection account after payment of certain fees and expenses and after payment of interest.

The securitized utility tariff bonds represent obligations only of the issuing entity, Atmos Energy Kansas Securitization I, LLC, and are secured only by the assets of the issuing entity, consisting principally of the securitized utility tariff property and related assets to support its obligations under the securitized utility tariff bonds. Please read “DESCRIPTION OF THE SECURITIZED UTILITY TARIFF BONDS—The Security for the Securitized Utility Tariff Bonds” and “DESCRIPTION OF THE SECURITIZED UTILITY TARIFF PROPERTY” in this prospectus. The securitized utility tariff property includes the right to impose, bill, charge, collect and receive securitized utility tariff charges from Atmos Energy’s retail customers in amounts sufficient to make payments on the securitized utility tariff bonds, as described further in this prospectus. Atmos Energy and its affiliates, other than the issuing entity, are not liable for any payments on the securitized utility tariff bonds. The securitized utility tariff bonds are not a debt or obligation of the State of Kansas or any of its political subdivisions, agencies or instrumentalities and are not a charge on its or any of its political subdivisions, agencies or instrumentalities’ full faith and credit or taxing power.

All matters relating to the structuring and pricing of the securitized utility tariff bonds have been considered by Atmos Energy and the State Corporation Commission of the State of Kansas, acting through its designated representative.

Neither the U.S. Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

The underwriter expects to deliver the securitized utility tariff bonds through the book-entry facilities of The Depository Trust Company for the accounts of its participants including Clearstream Banking, S.A. and Euroclear Banks SA/NV, as operator of the Euroclear System against payment on or about , 2023. There currently is no secondary market for the securitized utility tariff bonds, and we cannot assure you that one will develop.

ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement filed with the Securities and Exchange Commission or SEC. This prospectus provides information about us, the securitized utility tariff bonds and Atmos Energy Corporation as depositor, sponsor and initial servicer. This prospectus describes the terms of the securitized utility tariff bonds offered hereby. You should carefully review this prospectus, any free writing prospectus the issuing entity files with the SEC, and the information, if any, contained in the documents referenced in this prospectus under the heading “WHERE YOU CAN FIND MORE INFORMATION.”

References in this prospectus to the terms “we,” “us,” “our” or “the issuing entity” mean Atmos Energy Kansas Securitization I, LLC. References to “Atmos Energy,” “the sponsor,” “the initial servicer,” “the depositor” or “the seller” mean Atmos Energy Corporation. References to “the securitized utility tariff bonds” or “the bonds” mean our Series 2023-A Senior Secured Securitized Utility Tariff Bonds offered pursuant to this prospectus. References to “the servicer” refer to Atmos Energy and any successor servicer under the servicing agreement referred to in this prospectus. References to the “Securitization Act” mean the Utility Financing and Securitization Act, established by the Kansas Legislature, which provides for the securitization of “qualified extraordinary costs” (such as fuel costs incurred during extreme weather events) by issuing “securitized utility tariff bonds.” The Securitization Act is codified at K.S.A. §§ 66-1,240 – 66-1,253. Unless the context otherwise requires, the term “retail customer” means an end-use customer in Kansas who purchases natural gas for consumption from Atmos Energy. We also refer to the State Corporation Commission of the State of Kansas as “the Kansas commission.” You can find a glossary of some of the other defined terms we use in this prospectus on page 144 of this prospectus.

We have included cross-references to sections in this prospectus where you can find further related discussions. You can also find references to key topics in the table of contents.

Neither we nor any underwriter, agent, dealer, salesperson, the Kansas commission or Atmos Energy has authorized anyone else to provide you with any different information. Neither we nor any underwriter, agent, dealer, salesperson, the Kansas commission or Atmos Energy take any responsibility for, nor provide any assurance as to the reliability of, any different information that others may give you, or to make any representation other than those contained in this prospectus or in any free writing prospectus that we prepare. We are not offering to sell the securitized utility tariff bonds in any jurisdiction where the offer or sale is not permitted. The information in this prospectus is current only as of the date of this prospectus.

We expect to deliver the securitized utility tariff bonds against payment for the securitized utility tariff bonds on or about the date specified in the last paragraph of the cover page of this prospectus, which will be the business day following the date of pricing of the securitized utility tariff bonds. Since trades in the secondary market generally settle in two business days, purchasers who wish to trade securitized utility tariff bonds on the date of pricing or the succeeding business days will be required, by virtue of the fact that the securitized utility tariff bonds initially will settle in T + , to specify alternative settlement arrangements to prevent a failed settlement.

Trustee: |  | U.S. Bank Trust Company, National Association. Please read “THE TRUSTEE” in this prospectus for a description of the trustee’s duties and responsibilities under the Indenture.
Purpose of Transaction: |  | This issuance of the securitized utility tariff bonds will enable Atmos Energy to recover certain qualified extraordinary costs related to Winter Storm Uri. Please read “ATMOS ENERGY’S FINANCING ORDER” in this prospectus.
Transaction Overview: |  | In February 2021, Kansas experienced sub-zero temperatures brought by Winter Storm Uri, which led to a significant increase in demand for electricity and natural gas. Sub-zero temperatures and increased demand for electricity and natural gas caused by Winter Storm Uri placed significant stress on utilities, including Atmos Energy. Jurisdictional natural gas utilities were ordered to do everything necessary to ensure that natural gas service continued to be provided to their customers in Kansas.
|  | The Securitization Act permits utilities to utilize a financing mechanism through which it can recover “qualified extraordinary costs” (as defined in the Securitization Act) resulting from such storms by issuing securitized utility tariff bonds. Under the Securitization Act and the financing order (as defined below), Atmos Energy’s retail customers will pay securitized utility tariff charges, which are nonbypassable charges included in their monthly charges. These charges will fund payments of principal and interest on the securitized utility tariff bonds. Unless the context infers otherwise, references in this prospectus to the “financing order” are to the financing order issued by the Kansas commission in Atmos Energy’s Docket No. 22-ATMG-538-TAR on October 25, 2022.
|  | On October 25, 2022, the Kansas commission approved Atmos Energy’s application, as modified by the Kansas commission’s financing order. Accordingly, the Kansas commission: (1) authorized, subject to the terms of the financing order, the issuance of securitized utility tariff bonds in an aggregate amount not to exceed the qualified extraordinary costs and financing costs; (2) approved the creation of securitized utility tariff property consisting of the right to impose and collect securitized utility tariff charges in an amount to be calculated as provided in the financing order; (3) approved the form of tariff, as approved in the financing order, to implement the securitized utility tariff charges; (4) approved the securitization of qualified extraordinary costs, including upfront financing costs and ongoing financing cost estimates (subject to review of the Kansas commission’s designated representative); and (5) approved the review of the structure of the proposed securitization financing through a pre-issuance review and an issuance advice letter process.
|  | The primary transactions underlying the issuance and sale of the securitized utility tariff bonds are as follows:

The Security for the Securitized Utility Tariff Bonds: |  | The securitized utility tariff bonds will be secured by the collateral pledged pursuant to the Indenture. The principal asset of the trust estate will be the securitized utility tariff property. The Securitization Act and financing order provide for the creation and establishment of the securitized utility tariff property, which is a present contract right in favor of Atmos Energy, its transferees and other financing parties, to impose, bill, charge, collect and receive securitized utility tariff charges from Atmos Energy’s existing and future retail customers, as well as to obtain periodic adjustments to such charges as provided in the financing order. In addition, the securitized utility tariff property consists of all revenues, collections, claims, rights to payments, payments, money or proceeds arising from the aforementioned rights and interests.
|  | The Indenture’s trust estate will also consist of:
|  | •  our rights under the sale agreement pursuant to which we will acquire the securitized utility tariff property, under an administration agreement and under the bill of sale delivered by Atmos Energy pursuant to the sale agreement;
|  | •  our rights under the servicing agreement and any subservicing, agency, intercreditor or collection agreements executed in connection with the servicing agreement;
|  | •  the collection account for the securitized utility tariff bonds and all subaccounts of the collection account;
|  | •  all rights to compel the servicer to file for and obtain periodic adjustments to the securitized utility tariff charges in accordance with the Securitization Act and the financing order;

The Securitized Utility Tariff Property: |  | In general terms, all of the rights and interests of Atmos Energy that are transferred to us pursuant to the sale agreement are referred to in this prospectus as the “securitized utility tariff property.” The securitized utility tariff property includes the right to impose, bill, charge, collect and receive securitized utility tariff charges in amounts sufficient to pay principal and interest and ongoing financing costs in connection with the securitized utility tariff bonds, to obtain periodic adjustments to such charges as provided in the financing order and all revenues, collections, claims, rights to payments, payments, money or proceeds arising from the foregoing rights and interests. Securitized utility tariff charges are payable by Atmos Energy’s retail customers.
|  | The securitized utility tariff property is the principal collateral securing the securitized utility tariff bonds. Securitized utility tariff charges authorized in a financing order are irrevocable and not subject to reduction, impairment, or adjustment by further action of the Kansas commission, except for semi-annual and interim true-up adjustments to correct over-collections or under-collections and to provide for the expected recovery of amounts sufficient to timely provide payments of scheduled debt service and ongoing financing costs in connection with the securitized utility tariff bonds. See “ATMOS ENERGY’S FINANCING ORDER—True-Ups.” All revenues and collections resulting from securitized utility tariff charges are part of the securitized utility tariff property.
|  | We will purchase the securitized utility tariff property from Atmos Energy to support the issuance of the securitized utility tariff bonds. Atmos Energy, as the initial servicer, will bill and collect the securitized utility tariff charges from current and future retail customers. Atmos Energy will include the securitized utility tariff charges in its bills to its retail customers and is required to show the securitized utility tariff charges as a separate line item.

State and Kansas Commission Pledges: |  | The State of Kansas has pledged in the Securitization Act that it will not alter the provisions of the part of the Securitization Act which authorizes the Kansas commission to create an irrevocable contract right or chose in action by the issuance of a financing order, to create securitized utility tariff charges, and to make the securitized utility tariff charges imposed by a financing order irrevocable, binding and nonbypassable charges, taking or permitting any action that impairs or would impair the value of the securitized utility tariff property or the security for the securitized utility tariff bonds or revises the qualified extraordinary costs (as defined in the Securitization Act) for which recovery is authorized, or, except for adjustments discussed in “ATMOS ENERGY’S FINANCING ORDER—True-ups” and “THE SERVICING AGREEMENT—Securitized Utility Tariff Charge Adjustment Process” in this prospectus, or taking or permitting any action to reduce, alter or impair the securitized utility tariff charges that are to be imposed, billed, charged, collected and remitted for the benefit of the securitized utility tariff bondholders until the principal, interest and premium, if any, and any other charges incurred and contracts to be performed in connection with the securitized utility tariff bonds have been paid and performed in full. However, nothing will preclude limitation or alteration if full compensation is made by law for the full protection of the securitized utility tariff charges collected pursuant to the financing order and the full protection of the securitized utility tariff bondholders and any assignee or financing party. Please read “RISK FACTORS—Risks associated with potential judicial, legislative or regulatory actions” and “THE SECURITIZATION ACT—Atmos Energy May Securitize Qualified Extraordinary Costs and Related Upfront and Ongoing Financing Costs” in this prospectus.
|  | The Kansas commission has jurisdiction over Atmos Energy pursuant to K.S.A. §§ 66-1,200 et seq. The State of Kansas and its agencies, including the Kansas commission, have pledged that the State of Kansas and its agencies shall not (i) alter the statute that authorizes the creation of the securitized utility tariff property and the securitized utility tariff charges imposed by the financing order, which are irrevocable, binding or nonbypassable charges for all existing and future retail customers within the service area of the public utility, (ii) take or permit any action that impairs or would impair the value of the securitized utility tariff property or the security for the securitized utility tariff bonds, (iii) impair the rights and remedies of bondholders, assignees and financing parties in any way, or (iv) except for changes expressly allowed by law pursuant to the adjustment mechanism, reduce, alter, or impair the securitized utility tariff charges to be imposed, billed, charged, collected and remitted for the benefit of the securitized utility tariff bondholders until the securitized utility tariff bonds have been paid and performed in full. Please read “RISK FACTORS—Risks associated with potential judicial, legislative or regulatory actions” and “ATMOS ENERGY’S FINANCING ORDER—State and Commission Pledges” in the prospectus.
True-up Mechanism for Payment of Scheduled Principal and Interest: |  | Securitized utility tariff charges are required to be adjusted semi-annually to: •  correct any under-collection or over-collection of securitized utility tariff charges during the preceding six months; and •  ensure the expected recovery of amounts sufficient to timely provide all payments of debt service and other required amounts and charges in connection with the securitized utility tariff bonds.
|  | In addition to semi-annual true-up adjustments, additional true-up adjustments may be made more frequently at any time during the term of the securitized utility tariff bonds to correct any under- or over-collection in order to assure timely payment of the securitized utility

|  | tariff bonds as scheduled. During the year immediately preceding the scheduled final payment date for the securitized utility tariff bonds there will be quarterly true-up adjustments for the securitized utility tariff bonds that remain outstanding.
|  | In addition, with regard to the per-retail customer charge, if the customer count for a particular class of retail customers declines by more than 10% from that identified in Atmos Energy’s 2021 Annual Report filed with the Kansas commission, then the allocation factors for each class of retail customers will be recalculated using the most recent 12-month weather-normalized volume for each retail customer class in the next regular true-up.
|  | Please read “THE SECURITIZED UTILITY TARIFF CHARGES,” “ATMOS ENERGY’S FINANCING ORDER” and “THE SERVICING AGREEMENT—Securitized Utility Tariff Charge Adjustment Process” in this prospectus.
Nonbypassable Securitized Utility Tariff Charges: |  | The nonbypassable securitized utility tariff charges are applied to all existing and future retail customers receiving natural gas service from Atmos Energy or its successors or assignees under Kansas commission-approved rate schedules or under special contracts, even if a retail customer elects to purchase natural gas from an alternative natural gas supplier following a fundamental change in regulation of public utilities in Kansas; provided, however, if a customer disconnects from Atmos Energy’s gas distribution system and ceases to purchase natural gas by switching to an alternative source of energy that meets all of its energy needs, such customer would no longer be a retail customer and would not be subject to paying securitized utility tariff charges. Please read “THE SECURITIZED UTILITY TARIFF CHARGES,” “ATMOS ENERGY’S FINANCING ORDER” and “THE SERVICING AGREEMENT—Securitized Utility Tariff Charge Adjustment Process” in this prospectus.
Initial Securitized Utility Tariff Charge as a Percentage of Average Residential Customer’s Total Gas Bill: |  | Atmos Energy estimates that on an annualized basis the initial securitized utility tariff charges would represent approximately 7% of the total bill received by an average residential customer based on rates as of March 31, 2023.
Payment Dates: |  | Interest on the securitized utility tariff bonds is payable semi-annually on and . Interest will be calculated on a 30/360 basis. The first scheduled interest and principal payment date is , 2024.
Interest Payments: |  | Interest is due on each payment date. Interest will accrue with respect to the securitized utility tariff bonds from the date we issue the securitized utility tariff bonds at the interest rate specified in the table below.

Tranche |  | Interest Rate |
A |  |  | % |

|  | If any payment date is not a business day, payments scheduled to be made on such date may be made on the next succeeding business day and no interest shall accrue upon such payment during the intervening period.
|  | On each payment date, we will pay interest on the securitized utility tariff bonds equal to the following amounts:
|  | •  if there has been a payment default, any interest payable but unpaid on any prior payment dates, together with interest on such unpaid interest, if any; and

##### Table of Contents

|  | •  accrued interest on the principal balance of the securitized utility tariff bonds from the close of business on the preceding payment date, or the date of the original issuance of the securitized utility tariff bonds, as applicable, after giving effect to all payments of principal made on the preceding payment date, if any.
|  | We will pay interest on the securitized utility tariff bonds before we pay the principal of the securitized utility tariff bonds. Please read “DESCRIPTION OF THE SECURITIZED UTILITY TARIFF BONDS—Payments of Interest and Principal on the Securitized Utility Tariff Bonds” in this prospectus. We will calculate interest on the basis of a 360-day year consisting of 12, 30-day months.
Principal Payments and Record Dates and Payment Sources: |  | On each payment date for the securitized utility tariff bonds, referred to in this prospectus as a “payment date,” we will pay amounts of principal and interest then due or scheduled to be paid on the securitized utility tariff bonds from amounts available in the collection account and the related subaccounts held by the trustee. We will make these payments to the holders of record of the securitized utility tariff bonds on each record date, referred to in this prospectus as a “record date.” These available amounts, which will include the applicable securitized utility tariff charges collected by the servicer and remitted to the trustee since the last payment date, are described in greater detail under “DESCRIPTION OF THE SECURITIZED UTILITY TARIFF BONDS—The Collection Account for the Securitized Utility Tariff Bonds.” The trustee will pay the principal of securitized utility tariff bonds in the amounts and on the payment dates specified in the expected sinking fund schedule described in this prospectus, but only to the extent securitized utility tariff charge collections received from the servicer and amounts available from trust accounts held by the trustee are sufficient to make principal payments after payment of amounts having a higher priority of payment. Please read “DESCRIPTION OF THE SECURITIZED UTILITY TARIFF BONDS—How Funds in the Collection Account Will Be Allocated.”
|  | Failure to pay a scheduled principal payment on any payment date or the entire outstanding amount of the securitized utility tariff bonds by the scheduled final payment date will not result in a default. The failure to pay the entire outstanding principal balance of the securitized utility tariff bonds will result in a default only if such payment has not been made by the final maturity date.
|  | If there is a shortfall in the amounts available to make principal payments on the securitized utility tariff bonds that are due and payable, on or after the final maturity date or upon an acceleration following an event of default, the trustee will distribute principal first from the excess funds subaccount and second from the capital subaccount based on the principal amount then due and payable on the payment date.

|  | The amount of the servicer’s fee referred to in clause 2 above will be 0.05% of the aggregate initial principal amount of the securitized utility tariff bonds (for so long as Atmos Energy is the servicer) on an annualized basis. The priority of distributions for the collected securitized utility tariff charges, as well as available amounts in the subaccounts, are described in more detail under “DESCRIPTION OF THE SECURITIZED UTILITY TARIFF BONDS—How Funds in the Collection Account Will Be Allocated.”
Credit Enhancement: |  | The primary forms of credit enhancement are the true-up process and funds held in the collection account and related subaccounts.
|  | True-up Process. Securitized utility tariff charges are required to be adjusted at least semi-annually to:
|  | •  Correct any under-collection or over-collection of securitized utility tariff charges during the preceding six months; and
|  | •  ensure the expected recovery of amounts sufficient to timely provide all payments of debt service and other required amounts and charges in connection with the securitized utility tariff bonds.
|  | The servicer may also make interim true-up adjustments more frequently under certain circumstances. Please read “ATMOS ENERGY’S FINANCING ORDER—True-Ups.”
|  | Collection account. Under the Indenture, the trustee will hold a collection account for the securitized utility tariff bonds, divided into various subaccounts. The primary subaccounts for credit enhancement purposes are:
|  | •  the general subaccount—the trustee will deposit into the general subaccount all securitized utility tariff charge collections remitted to it by the servicer with respect to the securitized utility tariff bonds and investment earnings on amounts in the general subaccount;
|  | •  the capital subaccount—Atmos Energy will deposit an amount equal to 0.50% of the initial principal amount of the securitized utility tariff bonds into the capital subaccount on the date of issuance of the securitized utility tariff bonds; and
|  | •  the excess funds subaccount—any excess amount of collected securitized utility tariff charges held after the payment on a payment date of scheduled principal, interest and ongoing financing costs, and investment earnings on amounts in the excess funds subaccount of securitized utility tariff bonds will be held in the excess funds subaccount.
|  | Funds in each of these subaccounts will be available to make payments on the securitized utility tariff bonds on each payment date. In addition, other subaccounts may be used, including an over-collateralization subaccount or other subaccount if necessary to obtain certain tax treatment, desired ratings or otherwise increase the tangible and quantifiable benefits of the securitization. Atmos Energy may implement such subaccounts only with the agreement of the Kansas commission’s designated representative.

Reports to Holders of Securitized Utility Tariff Bonds: |  | Pursuant to the Indenture, the trustee shall make available electronically on its reporting website to each securitized utility tariff bondholder and the Kansas commission a statement provided and prepared by the servicer containing information concerning, among other things, us and the collateral for the securitized utility tariff bonds. Unless and until the securitized utility tariff bonds are issued in definitive certificated form, the reports for the securitized utility tariff bonds will be provided to The Depository Trust Company. The reports will be available to beneficial owners of the securitized utility tariff bonds on the reporting website of the trustee or upon written request to the trustee or the servicer. These reports will not be examined and reported upon by an independent public accountant. In addition, no independent public accountant will provide an opinion thereon. Furthermore, if required by the Trust Indenture Act, the trustee will be required to mail a brief annual report to all holders of securitized utility tariff bonds containing information concerning the trustee. Please read “DESCRIPTION OF THE SECURITIZED UTILITY TARIFF BONDS—Reports to Holders of the Securitized Utility Tariff Bonds” and “—The Trustee Must Provide an Annual Report to All Securitized Utility Tariff Bondholders.”
Servicing Compensation: |  | We will pay the servicer on each payment date the servicing fee with respect to the securitized utility tariff bonds. As long as Atmos Energy or any affiliated entity acts as servicer, this fee will be 0.05% of the aggregate initial principal amount of the securitized utility tariff bonds on an annualized basis, plus reimbursement for its out-of-pocket costs for external accounting and legal services. If a successor servicer is appointed, the servicing fee will be negotiated by the successor servicer and the trustee, but will not, unless the Kansas commission consents, exceed 0.60% of the aggregate initial principal amount of the securitized utility tariff bonds on an annualized basis. In no event will the trustee be liable for any servicing fee in its individual capacity.
Federal Income Tax Status: |  | Sidley Austin LLP expects to issue an opinion, that, for U.S. federal income tax purposes (i) we will not be treated as a taxable entity separate and apart from our sole member, Atmos Energy, and (ii) the securitized utility tariff bonds will constitute indebtedness of Atmos Energy. Each beneficial owner of a securitized utility tariff bond, by acquiring a beneficial interest, agrees to treat such securitized utility tariff bond as indebtedness of our sole member secured by the collateral for federal (and, to the extent applicable, state) income tax purposes unless otherwise required by appropriate taxing authorities. Please read “MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES” in this prospectus.
Kansas State Income Tax Status: |  | Triplett Woolf Garretson, LLC, counsel to us and Atmos Energy, expects to issue an opinion, that (i) assuming that the securitized utility tariff bonds will be treated as debt obligations of Atmos Energy for U.S. federal income tax purposes, interest paid on the securitized utility tariff bonds generally will be taxed for Kansas income tax purposes consistently with its taxation for U.S. federal income tax purposes and such interest received by an entity or person not otherwise subject to Kansas corporate or individual income tax will not be subject to Kansas income tax; (ii) assuming that such treatment applies for U.S. federal income tax purposes, for Kansas income tax purposes, we will not be treated as a taxable entity separate and apart from Atmos Energy; and (iii) assuming that such treatment applies for U.S. federal income tax purposes, for Kansas income tax purposes, the securitized utility tariff bonds will constitute indebtedness of Atmos Energy.

ERISA Considerations: |  | Employee benefit plans or other arrangements that are subject to ERISA, Section 4975 of the Internal Revenue Code or applicable similar law and investors acting on behalf of, or using assets of, such plans or arrangements may acquire the securitized utility tariff bonds subject to specified conditions. The acquisition, holding or disposition of the securitized utility tariff bonds could be treated as a direct or indirect prohibited transaction under ERISA and/or Section 4975 of the Internal Revenue Code or, in the case a plan or arrangement subject to applicable similar law, a violation of applicable similar law. Accordingly, by purchasing and holding the securitized utility tariff bonds, each investor that is or is acting on behalf of, or using assets of, such an employee benefit plan or arrangement subject to ERISA and/or Section 4975 of the Internal Revenue Code or applicable similar law will be deemed to certify by virtue of its acquisition of any securitized utility tariff bonds that the acquisition, holding and subsequent disposition of the securitized utility tariff bonds will not constitute or result in a non-exempt prohibited transaction under ERISA or Section 4975 of the Internal Revenue Code or, in the case of a plan or arrangement subject to applicable similar law, a non-exempt violation of applicable similar law. For further information, please read “ERISA CONSIDERATIONS” in this prospectus.
Credit Ratings: |  | The securitized utility tariff bonds are expected to receive credit ratings from at least two nationally recognized rating agencies. See “RATINGS FOR THE SECURITIZED UTILITY TARIFF BONDS” in this prospectus.
Use of Proceeds: |  | Upon the issuance and sale of the securitized utility tariff bonds, we will use the net proceeds to pay to Atmos Energy the purchase price of Atmos Energy’s rights under the financing order, which are securitized utility tariff property.
|  | The net proceeds from the sale of the securitized utility tariff property (after payment of upfront financing costs) will be used by Atmos Energy to recover, finance or refinance a portion of the qualified extraordinary costs of Atmos Energy as approved by the Kansas commission. Atmos Energy’s qualified extraordinary costs related to Winter Storm Uri are currently estimated to be approximately $125 million (including related financing costs). Please read “USE OF PROCEEDS” in the prospectus.
1940 Act Registration: |  | We expect to rely on an exception from the definition of “investment company” under the 1940 Act contained in Section 3(c)(5)(A) under the 1940 Act, although there may be additional exclusions or exemptions available to us. We are being structured so as not to constitute a “covered fund” for purposes of the Volcker Rule under the Dodd-Frank Act.
Risk Retention: |  | The securitized utility tariff bonds are not subject to the 5% risk retention requirements imposed by Section 15G of the Exchange Act due to the exemption provided in Rule 19(b)(8) of the risk retention regulations in 17 C.F.R. Part 246 of the Exchange Act or Regulation RR. For information regarding the requirements of the EU Securitization Regulation as to risk retention and other matters, please read “RISK FACTORS—Other risks associated with an investment in the securitized utility tariff bonds—Regulatory provisions affecting certain investors could adversely affect the liquidity and the regulatory treatment of investments in the securitized utility tariff bonds” in this prospectus.

RISK FACTORS

Please carefully consider all the information we have included or incorporated by reference in this prospectus, including the risks described below and in “CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING INFORMATION,” before deciding whether to invest in the securitized utility tariff bonds.

Summary of risk factors

Set forth below is a summary of the material risk factors which you should consider before deciding whether to invest in the securitized utility tariff bonds. These risks can affect the timing or ultimate payment of the securitized utility tariff bonds and the value of your investment in the securitized utility tariff bonds.

| • |  | You may experience material payment delays or incur a loss on your investment in the securitized utility tariff bonds because the source of funds for payment is limited.

Risks associated with potential judicial, legislative or regulatory actions

| • |  | We and Atmos Energy are not obligated to indemnify you for changes in law.

| • |  | Future judicial action could reduce the value of your investment in the securitized utility tariff bonds.

| • |  | Future state action could reduce the value of your investment in the securitized utility tariff bonds.

| • |  | The Kansas commission might attempt to take actions that could reduce the value of your investment in the securitized utility tariff bonds.

| • |  | Deregulation or restructuring in the natural gas utility market in Kansas may result in increased competition and material delays or reductions in collecting securitized utility tariff charges that could materially adversely affect the value of your investment in the securitized utility tariff bonds.

| • |  | The servicer may not fulfill its obligations to act on behalf of the securitized utility tariff bondholders to protect bondholders from actions by the Kansas commission or the State of Kansas, or the servicer may be unsuccessful in any such attempt.

| • |  | A municipal entity may seek to acquire portions of Atmos Energy’s distribution facilities and avoid payment of the securitized utility tariff charges.

Servicing risks

| • |  | Your investment in the securitized utility tariff bonds depends on Atmos Energy or its successor or assignee, acting as servicer of the securitized utility tariff property.

| • |  | Inaccurate customer count forecasting or unanticipated delinquencies or write-offs might reduce scheduled payments on the securitized utility tariff bonds.

| • |  | If we have to replace Atmos Energy as the servicer, we may experience difficulties finding and using a replacement servicer.

| • |  | Changes to billing and collection practices might reduce the value of your investment in the securitized utility tariff bonds.

| • |  | Limits on rights to terminate service might make it more difficult to collect the securitized utility tariff charges.

| • |  | Increased dependence on technology may hinder Atmos Energy’s ability to act as servicer of the securitized utility tariff property.

13

##### Table of Contents

| • |  | Cyber-attacks or acts of cyber-terrorism could disrupt Atmos Energy’s business operations and information technology systems or result in the loss or exposure of confidential or sensitive customer, employee or company information.

Weather-related damage and other disaster risks

| • |  | Adverse weather conditions causing damage to Atmos Energy’s operations could impair payment on the securitized utility tariff bonds.

| • |  | Terrorist activities or other significant events could adversely affect payment on the securitized utility tariff bonds.

Risks to natural gas industry

| • |  | Atmos Energy’s operations are subject to increased competition which could adversely affect the collection of securitized utility tariff charges.

| • |  | Greenhouse gas emissions or other legislation or regulations intended to address climate change could prompt Atmos Energy’s retail customers to switch to alternative energy sources and negatively impact the collection of securitized utility tariff charges.

Risks associated with the unusual nature of the securitized utility tariff property

| • |  | Future adjustments to securitized utility tariff charges by retail customer class might result in insufficient collection.

| • |  | Foreclosure of the trustee’s lien on the securitized utility tariff property might not be practical, and acceleration of the securitized utility tariff bonds before maturity might have little practical effect.

Risks associated with potential bankruptcy proceedings of the seller or the servicer

| • |  | The servicer will commingle the securitized utility tariff charges with other revenues it collects, which might obstruct access to the securitized utility tariff charges in case of the servicer’s bankruptcy and reduce the value of your investment in the securitized utility tariff bonds.

Discussion of risk factors

The following discussion provides additional information regarding each of our risk factors:

You may experience material payment delays or incur a loss on your investment in the securitized utility tariff bonds because the source of funds for payment is limited.

The only source of funds for payment of the securitized utility tariff bonds will be our assets, which consist of:

| • |  | the securitized utility tariff property securing the securitized utility tariff bonds, including the right to impose, bill, charge, collect and receive securitized utility tariff charges;

| • |  | the funds on deposit in the accounts held by the trustee; and

| • |  | our rights under various contracts we describe in this prospectus.

The securitized utility tariff bonds are not a charge on the full faith and credit or taxing power of the State of Kansas or any governmental agency or instrumentality, nor will the securitized utility tariff bonds be insured or guaranteed by Atmos Energy, including in its capacity as the sponsor, depositor, seller or initial servicer, or any of their respective affiliates (other than us), the trustee or any other person or entity. The securitized utility tariff bonds will be nonrecourse obligations, secured only by the collateral. Delays in payment on the securitized utility tariff bonds might result in a reduction in the market value of the securitized utility tariff bonds and, therefore, the value of your investment in the securitized utility tariff bonds. Thus, you must rely for payment of the securitized utility tariff bonds solely upon the collections of the securitized utility tariff charges, and funds on deposit in the accounts held by the trustee. Our organizational documents restrict our right to acquire other assets unrelated to the transactions described in this prospectus. Please read “ATMOS ENERGY KANSAS SECURITIZATION I, LLC, THE ISSUING ENTITY” in this prospectus.

Risks associated with potential judicial, legislative or regulatory actions

We and Atmos Energy are not obligated to indemnify you for changes in law.

Neither we nor Atmos Energy, nor any affiliate, successor or assignee, will indemnify you for any changes in the law, including any federal preemption or repeal or amendment of the Securitization Act, that might affect the value of the securitized utility tariff bonds. Atmos Energy will agree in the sale agreement to institute any legal or administrative action or proceeding as may be reasonably necessary to block or overturn any attempts to cause a repeal, modification or amendment of the Securitization Act that would be materially adverse to us, the

15

##### Table of Contents

trustee or the securitized utility tariff bondholders. However, we cannot assure you that Atmos Energy would be able to take this action or that any such action would be successful. Although Atmos Energy or any successor assignee might be required to indemnify us if legal action based on the law in effect at the time of the issuance of the securitized utility tariff bonds invalidates the securitized utility tariff property, such indemnification obligations do not apply for any changes in law after the date the securitized utility tariff bonds are issued, whether such changes in law are effected by means of any legislative enactment, any constitutional amendment or any final and non-appealable judicial decision. Please read “THE SALE AGREEMENT—Atmos Energy’s Covenants” in this prospectus.

Future judicial action could reduce the value of your investment in the securitized utility tariff bonds.

The securitized utility tariff property is the creation of the Securitization Act and the financing order that has been issued by the Kansas commission to Atmos Energy pursuant to the Securitization Act. The Securitization Act was enacted in April 2021. There is uncertainty associated with investing in bonds payable from an asset that depends for its existence on legislation because there is limited judicial or regulatory experience implementing and interpreting the legislation. The Securitization Act or any financing order or any provisions thereof might be directly contested in courts or otherwise become the subject of litigation. Because the securitized utility tariff property is a creation of the Securitization Act and the financing order, any judicial determination affecting the validity of or interpreting the Securitization Act or the financing order, the securitized utility tariff property or our ability to make payments on the securitized utility tariff bonds might have an adverse effect on the value of the securitized utility tariff bonds or cause a delay in the recovery of your investment. As of the date of this prospectus, no such litigation has arisen; however, we cannot assure you that a lawsuit challenging the validity of the Securitization Act or any financing order will not be filed in the future or that, if filed, such lawsuit will not be successful. If an invalidation of any relevant underlying legislative provision or any financing order provision were to result from such litigation, you might lose some or all of your investment or might experience delays in recovering your investment. Please read “THE SECURITIZATION ACT—Constitutional Matters” in this prospectus.

Other states have passed laws with financing provisions similar to some provisions of the Securitization Act, and some of these laws have been challenged by judicial actions or utility commission proceedings. To date, none of these challenges has succeeded, but future judicial challenges might be made. An unfavorable decision regarding another state’s law would not automatically invalidate the Securitization Act or the financing order, but it might provoke a challenge to the Securitization Act or the financing order, establish a legal precedent for a successful challenge to the Securitization Act or the financing order or heighten awareness of the political and other risks of the securitized utility tariff bonds, and in that way may limit the liquidity and value of the securitized utility tariff bonds. Therefore, legal activity in other states may indirectly affect the value of your investment in the securitized utility tariff bonds.

Future state action could reduce the value of your investment in the securitized utility tariff bonds.

Despite the State’s pledge and the Kansas commission’s pledge in the Securitization Act and the financing order, respectively, not to take or permit certain actions that would impair the value of the securitized utility tariff property or the securitized utility tariff charges, the Kansas legislature might attempt to repeal or amend the Securitization Act in a manner that limits or alters the securitized utility tariff property so as to reduce its value. For a description of the State’s pledge, please read “THE SECURITIZATION ACT—Atmos Energy May Securitize Qualified Extraordinary Costs and Related Upfront and Ongoing Financing Costs” in this prospectus. As of the date of this prospectus, we are not aware of any pending legislation in the Kansas legislature that would affect any provisions of the Securitization Act.

It might be possible for the Kansas legislature to repeal or amend the Securitization Act notwithstanding the State’s pledge if the legislature acts in order to serve a significant and legitimate public purpose, such as protecting the public health and safety, or responding to a national or regional catastrophe or emergency affecting

16

##### Table of Contents

Atmos Energy’s service area, or if such action or inaction otherwise is in the valid exercise of the State’s police power. Similarly, it might be possible for the Kansas commission to repeal or amend the financing order notwithstanding the Kansas commission’s pledge if it acts in order to serve a significant and legitimate public purpose. Any such action, as well as the costly and time-consuming litigation that likely would ensue, might adversely affect the price and liquidity, the dates of payment of interest and principal and the weighted average lives of the securitized utility tariff bonds. Moreover, the outcome of any litigation cannot be predicted. Accordingly, you might incur a loss on or delay in recovery of your investment in the securitized utility tariff bonds.

Except as described in “THE SALE AGREEMENT—Atmos Energy’s Obligation to Indemnify Us and the Trustee and to Take Legal Action” in this prospectus, neither we, Atmos Energy, nor any of its successors, assignees or affiliates will indemnify you for any change in law, including any amendment or repeal of the Securitization Act, that might affect the value of the securitized utility tariff bonds.

If an action of the Kansas legislature or the Kansas commission adversely affecting the securitized utility tariff property or the ability to collect securitized utility tariff charges were considered a “taking” under the United States or Kansas Constitutions, the State of Kansas might be obligated to pay compensation in an amount equal to the estimated value of the securitized utility tariff property at the time of the taking. However, even in that event, there is no assurance that any amount provided as compensation would be sufficient for you to recover fully your investment in the securitized utility tariff bonds or to offset interest lost pending such recovery.

Nothing in the State’s or Kansas commission’s pledge precludes any limitation or alteration of the Securitization Act or the financing order if full compensation is made by law for the full protection of the securitized utility tariff charges collected pursuant to the financing order and of the securitized utility tariff bondholders. It is unclear what “full compensation” and “full protection” would be afforded to the securitized utility tariff bondholders by the State of Kansas or the Kansas commission if such limitation or alteration were attempted.

Unlike the citizens of some other states, the citizens of the State of Kansas currently do not have the constitutional right to adopt or revise state laws by initiative or referendum. Thus, absent an amendment to the Kansas Constitution, the Securitization Act cannot be amended or repealed by direct action of the electorate of the State of Kansas.

The enforcement of any rights against the State of Kansas or the Kansas commission under their respective pledges may be subject to the exercise of judicial discretion in appropriate cases and to the limitations on legal remedies against state and local governmental entities in Kansas. These limitations might include, for example, the necessity to exhaust administrative remedies prior to bringing suit in a court, or limitations on type and locations of courts in which the State of Kansas or the Kansas commission may be sued, or limitations on awards or collection of damages.

The Kansas commission might attempt to take actions that could reduce the value of your investment in the securitized utility tariff bonds.

The Securitization Act provides that for a financing order issued to create securitized utility tariff property, the financing order must provide that the financing order is irrevocable and that the Kansas commission may not directly or indirectly, by any subsequent action, amend, modify or terminate a financing order or reduce, impair, postpone, terminate or otherwise adjust the securitized utility tariff charges authorized under a financing order, except for the true-up adjustments to the securitized utility tariff charges. In addition, the Kansas commission had pledged in the financing order that it will not amend, modify, or rescind the financing order by any subsequent action or reduce, impair, postpone, terminate, or otherwise adjust the securitized utility tariff charges. However, the Kansas commission retains the power to adopt, revise or rescind rules or regulations affecting Atmos Energy or a successor utility. The Kansas commission also retains the power to interpret the financing order granted to

17

##### Table of Contents

Atmos Energy, and in that capacity might be called upon to rule on the meanings of provisions of the financing order that might need further elaboration. Any new or amended regulations or orders from the Kansas commission might adversely affect the ability of the servicer to disconnect customers for nonpayment, assess late fees, impose deposit requirements or collect the securitized utility tariff charges in full and on a timely basis, which may negatively impact the rating of the securitized utility tariff bonds or their price and, accordingly, the amortization of the securitized utility tariff bonds and their weighted average lives.

The servicer is required to file with the Kansas commission, on our behalf, certain periodic true-up adjustments of the securitized utility tariff charges. The Kansas commission has 30 days after the date of a true-up adjustment filing to confirm the mathematical accuracy of the servicer’s adjustment and to confirm that there are no clerical errors. Any true-up adjustment filed with the Kansas commission will take effect on its proposed effective date, which shall not be less than 30 days after filing. Please read “ATMOS ENERGY’S FINANCING ORDER—True-ups” and “—Adjustments to Allocation of Securitized Utility Tariff Charges” in this prospectus. True-up adjustment procedures may be challenged in the future. Challenges to or delays in the true-up process might adversely affect the market perception and valuation of the securitized utility tariff bonds. Also, any litigation might materially delay securitized utility tariff charge collections due to delayed implementation of true-up adjustments and might result in missing payments or payment delays and lengthened weighted average life of the securitized utility tariff bonds.

Deregulation or restructuring in the natural gas utility market in Kansas may result in increased competition and material delays or reductions in collecting securitized utility tariff charges that could materially adversely affect the value of your investment in the securitized utility tariff bonds.

Future deregulation of the natural gas utility market in Kansas could change how natural gas services are provided to retail customers and allow new competitive market entrants to provide retail natural gas service, provide metering services, provide billing services or collect payments (including the securitized utility tariff charges) from retail customers. We cannot predict if or when it will be subject to changes in legislation or regulation, nor can it predict the impact of these changes. Poor performance, inaction, failure to abide by contractual obligations, commingling of funds, lack of creditworthiness, insolvency or other unforeseen problems with respect to any service provider could result in material delays or reductions in calculating and collecting securitized utility tariff charges and therefore material delays or reductions of payments of principal and interest on the securitized utility tariff bonds and could materially reduce the value of your investment in the securitized utility tariff bonds.

The servicer may not fulfill its obligations to act on behalf of the securitized utility tariff bondholders to protect bondholders from actions by the Kansas commission or the State of Kansas, or the servicer may be unsuccessful in any such attempt.

The servicer will agree in the servicing agreement to take any action or proceeding reasonably necessary to compel performance by the Kansas commission and the State of Kansas of any of their obligations or duties under the securitization provisions of the Securitization Act or the financing order, including any actions reasonably necessary to block or overturn any attempts to cause a repeal, or modification of, or supplement to the securitization provisions of the Securitization Act or the financing order or the rights of bondholders in the securitized utility tariff property by executive action, legislative enactment, constitutional amendment or other means that would be adverse to the bondholders. The servicer, however, may not be able to take those actions for a number of reasons, including due to legal or regulatory restrictions, financial constraints and practical difficulties in successfully challenging any such legislative enactment or constitutional amendment. Additionally, any action the servicer is able to take may not be successful. Any such failure to perform its obligations or to successfully compel performance by the Kansas commission or the State of Kansas could negatively affect bondholders’ rights and result in a loss of their investment in the securitized utility tariff bonds.

##### Table of Contents

A municipal entity may seek to acquire portions of Atmos Energy’s gas distribution facilities and avoid payment of the securitized utility tariff charges.

Kansas law authorizes municipalities to seek to acquire portions of a utility’s gas distribution facilities through voluntary transactions or the power of expropriation for use as part of municipally owned utility systems. There can be no assurance that one or more municipalities will not seek to acquire some or all of Atmos Energy’s gas distribution facilities while the securitized utility tariff bonds remain outstanding. The Securitization Act specifies that securitized utility tariff charges approved by a financing order shall be collected by a utility as well as its “successors or assignees.” In the servicing agreement, Atmos Energy has covenanted to assert in an appropriate forum that any municipality that acquires any portion of Atmos Energy’s gas distribution facilities by expropriation, including upon the expiration of any franchise agreement, must be treated as a successor to Atmos Energy under the Securitization Act and the financing order. However, the involved municipality might assert that it should not be treated as a successor to Atmos Energy for these purposes and that its distribution customers are not responsible for payment of securitized utility tariff charges. In any case, we cannot assure you that the securitized utility tariff charges will be collected from customers of municipally owned utilities who were formerly retail customers of Atmos Energy and that such an occurrence might not affect the timing or receipt of payments with respect to the securitized utility tariff bonds.

Servicing risks

Your investment in the securitized utility tariff bonds depends on Atmos Energy or its successor or assignee, acting as servicer of the securitized utility tariff property.

Atmos Energy, as initial servicer, will be responsible for, among other things, calculating, billing and collecting the securitized utility tariff charges from its retail customers, submitting requests to the Kansas commission to adjust these charges, monitoring the collateral for the securitized utility tariff bonds and taking certain actions in the event of non-payment by a retail customer. The trustee’s receipt of collections in respect of the securitized utility tariff charges, which will be used to make payments on the securitized utility tariff bonds, will depend in part on the skill and diligence of the servicer in performing these functions. The systems that the servicer has in place for securitized utility tariff charge billings and collections, the operations to provide service to the relevant customers, together with the regulations of the Kansas commission governing utilities such as Atmos Energy might, in particular circumstances, cause the servicer to experience difficulty in performing these functions in a timely and completely accurate manner. If the servicer fails to make securitized utility tariff charge collections for any reason, then the servicer’s payments to the trustee in respect of the securitized utility tariff charges might be delayed or reduced. In that event, our payments on the securitized utility tariff bonds might be delayed or reduced.

Inaccurate customer count forecasting or unanticipated delinquencies or write-offs might reduce scheduled payments on the securitized utility tariff bonds.

The securitized utility tariff charges are generally assessed based on forecasted customer counts for each retail customer class. The amount and the rate of securitized utility tariff charge collections will depend on the actual number of retail customers and the amount of securitized utility tariff charge collections and write-offs for each retail customer class. The securitized utility tariff charges are calculated by the servicer according to the methodology approved in the financing order, which includes the allocation of cost responsibility among retail customer classes. If the servicer inaccurately forecasts customer counts (including forecasts within each retail customer class) or underestimates customer delinquency or write-off data when setting or adjusting the securitized utility tariff charges, there could be a shortfall or material delay in securitized utility tariff charge collections, which might result in missed or delayed payments of principal and interest and lengthened weighted average lives of the securitized utility tariff bonds. Please read “ATMOS ENERGY’S FINANCING ORDER—True-Ups” and “—Adjustments to Allocation of Securitized Utility Tariff Charges” in this prospectus.

The servicer’s use of inaccurate delinquency or write-off rates might also result from, among other things, unexpected deterioration of the economy or the occurrence of a natural disaster or extreme weather, an act of

19

##### Table of Contents

terrorism, cyberattack or other catastrophic event or the unanticipated declaration of a moratorium on terminating natural gas service to retail customers in the event of such occurrences, any of which would cause greater delinquencies or write-offs than expected or force Atmos Energy to grant additional payment relief to more retail customers, or any other change in law that makes it more difficult for Atmos Energy to terminate service to nonpaying retail customers or that requires Atmos Energy to apply more lenient credit standards in accepting retail customers. For example, under its emergency powers, the State legislature or the Kansas commission could impose a moratorium on the payment of consumer bills.

If we have to replace Atmos Energy as the servicer, we may experience difficulties finding and using a replacement servicer.

If Atmos Energy ceases to service the securitized utility tariff property, it might be difficult to find a successor servicer. Under the financing order, the annual servicing fee payable to a successor servicer is capped and the payment of compensation in excess of the cap is dependent upon Kansas commission approval. Also, any successor servicer might have less experience and ability than Atmos Energy and might experience difficulties in collecting securitized utility tariff charges and determining appropriate adjustments to the securitized utility tariff charges and billing and/or payment arrangements may change, resulting in delays or disruptions in collections. A successor servicer might charge fees that, while permitted under the financing order, are substantially higher than the fees paid to Atmos Energy as the initial servicer. Although a true-up adjustment may be required to allow for the increase in fees, there could be a gap between the incurrence of those fees and the implementation of the true-up adjustment to adjust for the increase that might adversely affect distributions from the collection account. In the event of the commencement of a case by or against the servicer under the Bankruptcy Code or similar laws, we and the trustee might be prevented from effecting a transfer of servicing due to operation of the Bankruptcy Code. Any of these factors and others might delay the timing of payments and may reduce the value of your investment. Please read “THE SERVICING AGREEMENT” in this prospectus.

Changes to billing and collection practices might reduce the value of your investment in the securitized utility tariff bonds.

The financing order specifies the methodology for determining the amount of the securitized utility tariff charges we may impose. The servicer may not change this methodology without approval from the Kansas commission. However, the servicer may set its own billing and collection arrangements with its customers, provided that these arrangements comply with the Kansas commission’s customer safeguards. For example, to recover part of an outstanding bill, the servicer may agree to extend a customer’s payment schedule or to write-off the remaining unpaid portion of the bill, including the securitized utility tariff charges. Also, the servicer may change billing and collection practices, which might adversely impact the timing and amount of retail customer payments and might reduce securitized utility tariff charge collections, thereby limiting our ability to make scheduled payments on the securitized utility tariff bonds. Separately, the Kansas commission might require changes to these practices. Any changes in billing and collection practices regulations might make it more difficult for the servicer to collect the securitized utility tariff charges and adversely affect the value of your investment in the securitized utility tariff bonds. Please read “THE DEPOSITOR, SELLER, INITIAL SERVICER AND SPONSOR—Forecasting Natural Gas Customers,” “—Billing Process and Payment Options” and “—Collection, Termination of Service and Write-off Policy” in this prospectus.

Consumer protection measures may limit the ability of Atmos Energy to collect all charges owed by consumers, including the securitized utility tariff charges. In addition, the State legislature or the Kansas commission may take actions in response to pandemics, natural disasters, adverse weather events or any other situation which may adversely affect the timing of securitized utility tariff charge collections. Any such action could result in a shortfall or material delay in securitized utility tariff charge collections, which in turn might result in missed or delayed payments of principal and interest, lengthened weighted average life of the securitized utility tariff bonds and downgrade of the credit ratings on the securitized utility tariff bonds.

##### Table of Contents

In addition, COVID-19 or any future pandemic may impact the ability of Atmos Energy to maintain operations at the same level as it was able prior to the pandemic. For instance, a large portion of Atmos Energy’s workforce, including employees of their contractors, may be unable to perform their job functions effectively due to illness, family illness, quarantine requirements, social distancing, telework requirements and other impacts of the COVID-19 or any future pandemic. Such potential impacts may limit the ability of Atmos Energy to service the securitized utility tariff charges.

Limits on rights to terminate service might make it more difficult to collect the securitized utility tariff charges.

If Atmos Energy, as the servicer, is billing retail customers for securitized utility tariff charges, it may terminate service to the retail customer for non-payment of securitized utility tariff charges pursuant to the applicable rules of the Kansas commission. Nonetheless, the rules and regulations of the Kansas commission, which may change from time to time, regulate and control the right to disconnect service. For example, gas utilities generally may not terminate service to a customer (i) on a holiday or weekend day or (ii) during certain extreme weather conditions. To the extent these retail customers do not pay for their gas service, Atmos Energy will not be able to collect securitized utility tariff charges from these retail customers.

In addition, Atmos Energy may be limited in the future in its ability to terminate service or collect securitized utility tariff charges. The Kansas commission, in response to a federal mandate or otherwise, could impose restrictions on the rates Atmos Energy charges to provide its services, including the inability to implement approved rates, or delay actions with respect to Atmos Energy’s base rate case and filings.

Increased dependence on technology may hinder Atmos Energy’s ability to act as servicer of the securitized utility tariff property.

Over the last several years, Atmos Energy has implemented or acquired a variety of technological tools including both Atmos Energy-owned information technology and technological services provided by outside parties. These tools and systems support critical functions including, scheduling and dispatching of service technicians, automated meter reading systems, customer care and billing, operational plant logistics, management reporting, and external financial reporting. The failure of these or other similarly important technologies, or Atmos Energy’s inability to have these technologies supported, updated, expanded, or integrated into other technologies, could hinder its business operations and adversely impact its ability to act as servicer of the securitized utility tariff property.

Although Atmos Energy has, when possible, developed alternative sources of technology and built redundancy into its computer networks and tools, there can be no assurance that these efforts would protect against all potential issues related to the loss of any such technologies.

Cyber-attacks or acts of cyber-terrorism could disrupt Atmos Energy’s business operations and information technology systems or result in the loss or exposure of confidential or sensitive customer, employee or company information.

Atmos Energy’s business operations and information technology systems may be vulnerable to an attack by individuals or organizations intending to disrupt its business operations and information technology systems, even though Atmos Energy has implemented policies, procedures and controls to prevent and detect these activities. Atmos Energy uses its information technology systems to manage its distribution and intrastate pipeline and storage operations and other business processes. Disruption of those systems could adversely impact Atmos Energy’s ability to safely deliver natural gas to its customers, operate its pipeline and storage systems or otherwise service the securitized utility tariff property.

In addition, Atmos Energy uses its information technology systems to protect confidential or sensitive customer, employee and company information developed and maintained in the normal course of its business. Any attack on such systems that would result in the unauthorized release of customer, employee or other confidential or sensitive data could have a material adverse effect on Atmos Energy’s business reputation,

21

##### Table of Contents

increase its costs and expose Atmos Energy to additional material legal claims and liability, which could impact Atmos Energy’s ability to service the securitized utility tariff property.

Weather-related damage and other disaster risks

Adverse weather conditions causing damage to Atmos Energy’s operations could impair payment on the securitized utility tariff bonds.

Atmos Energy has weather-normalized rates for approximately 96 percent of its residential and commercial revenues in its distribution operations, which substantially mitigates the adverse effects of warmer-than-normal weather for meters in those service areas. However, there is no assurance that Atmos Energy will continue to receive such regulatory protection from adverse weather in its rates in the future. Atmos Energy’s operations were impacted by Winter Storm Uri and might be impacted by tornadoes, thunderstorms, ice storms, windstorms, flooding, earthquakes, prolonged droughts and the occurrence of wildfires, among other events. There could be longer-lasting weather-related adverse effects on residential and commercial development and economic activity in Atmos Energy’s service area, which could reduce the retail customer count and cause the securitized utility tariff charges to be greater than expected as a percentage of base rates of remaining retail customers. Legislative action adverse to the securitized utility tariff bondholders might be taken in response, and such legislation, if challenged as violative of the State pledge, might be defended on the basis of public necessity.

Terrorist activities or other significant events could adversely affect payment on the securitized utility tariff bonds.

The threat of terrorist activities could lead to increased economic instability and volatility in the price of natural gas that could affect Atmos Energy’s customer count and cause the securitized utility tariff charges to be greater than expected as a percentage of base rates of remaining customers. Also, companies in the natural gas industry may face a heightened risk of exposure to actual acts of terrorism, which could subject Atmos Energy’s operations to increased risks. As a result, the availability of insurance covering such risks may become more limited, which could increase the risk that an event could adversely affect Atmos Energy’s business operations, ability to act as servicer, and payment on the securitized utility tariff bonds.

Risks to natural gas industry

Atmos Energy’s operations are subject to increased competition which could adversely affect the collection of securitized utility tariff charges.

In residential and commercial customer markets, Atmos Energy’s distribution operations compete with other energy products, such as electricity and propane. Increases in the price of natural gas could negatively impact Atmos Energy’s competitive position by decreasing the price benefits of natural gas to the consumer. This could have the potential to cause a decline in the number of Atmos Energy’s retail customers. A decline in Atmos Energy’s retail customers receiving natural gas by means of Atmos Energy’s distribution facilities would cause the securitized utility tariff charges to the remaining retail customers to increase, and thereby increase the risk of nonpayment by retail customers.

In the case of industrial customers, such as manufacturing plants, adverse economic conditions, including higher gas costs, could cause these customers to use alternative sources of energy, such as electricity, or bypass Atmos Energy’s systems in favor of special competitive contracts with lower per-unit costs. Although currently natural gas is relatively more efficient than electricity and cheaper than electricity on a per unit basis, and switching energy sources entails significant upfront costs, changes in the competitive position of natural gas relative to electricity and other energy products have the potential to cause a decline in the number of Atmos Energy’s retail customers. A decline in Atmos Energy’s retail customers receiving natural gas by means of Atmos Energy’s distribution facilities would cause the securitized utility tariff charges to the remaining retail customers to increase, and thereby increase the risk of nonpayment by retail customers.

##### Table of Contents

Greenhouse gas emissions or other legislation or regulations intended to address climate change could prompt Atmos Energy’s retail customers to switch to alternative energy sources and negatively impact the collection of securitized utility tariff charges.

Federal, regional and/or state legislative and/or regulatory initiatives may attempt to control or limit the causes of climate change, including greenhouse gas emissions, such as carbon dioxide and methane. Such laws or regulations could impose costs tied to greenhouse gas emissions, operational requirements or restrictions, or additional charges to fund energy efficiency activities. They could also provide a cost advantage to alternative energy sources, impose costs or restrictions on end users of natural gas, or result in other costs or requirements, such as costs associated with the adoption of new infrastructure and technology to respond to new mandates. The focus on climate change could adversely impact the reputation of fossil fuel products or services. The occurrence of the foregoing events could put upward pressure on the cost of natural gas relative to other energy sources, increase Atmos Energy’s costs and the prices it charges to retail customers, reduce the demand for natural gas, and impact the competitive position of natural gas and the ability to serve new or existing retail customers.

Any or all of these items might prompt Atmos Energy’s retail customers to switch to alternative sources to meet their energy requirements and disconnect from Atmos Energy’s gas distribution system. This could reduce Atmos Energy’s retail customer count, resulting in higher securitized utility tariff charges for Atmos Energy’s remaining retail customers. This, in turn, could adversely impact the billing and collection of securitized utility tariff charges, thereby increasing the risk of nonpayment by retail customers.

Risks associated with the unusual nature of the securitized utility tariff property

Future adjustments to securitized utility tariff charges by retail customer class might result in insufficient collection.

The retail customers who pay the securitized utility tariff charges are divided into customer classes. Securitized utility tariff charges will be allocated among retail customer classes and assessed in accordance with the retail customer billing mechanism specified in the financing order. The true-up adjustment methodology approved in the financing order is cross collateralized across retail customer classes and requires that any delinquencies or under-collections in one retail customer class will be taken into account in the application of the true-up mechanism to adjust the securitized utility tariff charges for all retail customers, not just the class of retail customers from which the delinquency or under-collection arose. Nonetheless, if enough retail customers in a class fail to pay securitized utility tariff charges or cease to be retail customers, the servicer might have to substantially increase the securitized utility tariff charges for the remaining retail customers in that retail customer class and for other retail customer classes as well. These increases could lead to further unanticipated failures by the remaining retail customers to pay securitized utility tariff charges, thereby increasing the risk of a shortfall in funds to pay interest and principal on the securitized utility tariff bonds.

Foreclosure of the trustee’s lien on the securitized utility tariff property might not be practical, and acceleration of the securitized utility tariff bonds before maturity might have little practical effect.

Under the Securitization Act and the Indenture, the trustee or the securitized utility tariff bondholders have the right to foreclose or otherwise enforce the lien on the securitized utility tariff property securing the securitized utility tariff bonds. However, in the event of foreclosure, there is likely to be a limited market, if any, for the securitized utility tariff property. Therefore, foreclosure might not be a realistic or practical remedy. Moreover, although principal of the securitized utility tariff bonds will be due and payable upon acceleration of the securitized utility tariff bonds before maturity, securitized utility tariff charges likely would not be accelerated and the nature of our business will result in the principal of the securitized utility tariff bonds being paid as funds become available.

The servicer will commingle the securitized utility tariff charges with other revenues it collects, which might obstruct access to the securitized utility tariff charges in case of the servicer’s bankruptcy and reduce the value of your investment in the securitized utility tariff bonds.

The servicer will remit collected securitized utility tariff charges (the “daily remittance”) to the trustee for deposit to the general subaccount of the collection account as soon as reasonably practicable, but in no event later than two servicer business days following such date. The servicer will not segregate the securitized utility tariff charges from the other funds it collects from customers or its general funds. The securitized utility tariff charges will be segregated only when the servicer pays them to the trustee.

Despite this requirement, the servicer might fail to remit the full amount of the securitized utility tariff charges to the trustee or might fail to do so on a timely basis. This failure, whether voluntary or involuntary, might materially reduce the amount of securitized utility tariff charge collections available to make payments on the securitized utility tariff bonds.

The Securitization Act provides that the priority of a security interest perfected in securitized utility tariff property is not impaired by the commingling of the funds arising from securitized utility tariff charges with any other funds of the servicer. In a bankruptcy of the servicer, however, a bankruptcy court might rule that federal bankruptcy law does not recognize our right to collections of the securitized utility tariff charges that are commingled with other funds of the servicer as of the date of bankruptcy. If so, the collections of the securitized utility tariff charges held by the servicer as of the date of bankruptcy would not be available to pay amounts owed on the securitized utility tariff bonds. In this case, we would have only a general unsecured claim against the servicer for those amounts. This decision could cause material delays in payments of principal or interest, or losses, on the securitized utility tariff bonds and could materially reduce the value of your investment in the securitized utility tariff bonds.

The bankruptcy of Atmos Energy might result in losses or delays in payments on the securitized utility tariff bonds.

The Securitization Act and the financing order provide that as a matter of Kansas state law:

| • |  | the rights and interests of a selling utility under a financing order, including the right to impose, bill, charge, collect and receive securitized utility tariff charges, are contract rights of the seller;

| • |  | the seller may make a present transfer of its rights under a financing order, including the right to impose, bill, charge, collect and receive future securitized utility tariff charges that retail customers do not yet owe;

| • |  | the securitized utility tariff property constitutes a present contract right, even though the imposition and collection of securitized utility tariff charges depend on further acts that have not yet occurred; and

| • |  | a transfer of the securitized utility tariff property from the seller, or its affiliate, to us, under an agreement that expressly states the transfer is a sale or other absolute transfer, is a true sale of the securitized utility tariff property and not a pledge of the securitized utility tariff property to secure a financing by the seller.

Please read “THE SECURITIZATION ACT” in this prospectus. These provisions are important to maintaining payments on the securitized utility tariff bonds in accordance with their terms during any bankruptcy of Atmos Energy. In addition, the transaction has been structured with the objective of keeping us legally separate from Atmos Energy and its affiliates in the event of a bankruptcy of Atmos Energy or any such affiliates.

A bankruptcy court generally follows state property law on issues such as those addressed by the state law provisions described above. However, a bankruptcy court does not follow state law if it determines that the state law is contrary to a paramount federal bankruptcy policy or interest. If a bankruptcy court in a Atmos Energy

24

##### Table of Contents

bankruptcy refused to enforce one or more of the state property law provisions described above, the effect of this decision on you as a beneficial owner of the securitized utility tariff bonds might be similar to the treatment you would receive in a Atmos Energy bankruptcy if the securitized utility tariff bonds had been issued directly by Atmos Energy. A decision by the bankruptcy court that, despite our separateness from Atmos Energy, our assets and liabilities and those of Atmos Energy should be substantively consolidated would have a similar effect on you as a bondholder.

We have taken steps together with Atmos Energy, as the seller, to reduce the risk that in the event the seller or an affiliate of the seller were to become the debtor in a bankruptcy case, a court would order that our assets and liabilities be substantively consolidated with those of Atmos Energy or an affiliate. Nonetheless, these steps might not be completely effective, and thus if Atmos Energy or an affiliate were to become a debtor in a bankruptcy case, a court might order that our assets and liabilities be substantively consolidated with those of Atmos Energy or such affiliate. This might cause material delays in payment of, or losses on, the securitized utility tariff bonds and might materially reduce the value of your investment in the securitized utility tariff bonds. For example:

| • |  | without permission from the bankruptcy court, the trustee might be prevented from taking actions against Atmos Energy or recovering or using funds on your behalf or replacing Atmos Energy as the servicer;

| • |  | the bankruptcy court might order the trustee to exchange the securitized utility tariff property for other property of lower value;

| • |  | tax or other government liens on Atmos Energy’s property might have priority over the trustee’s lien and might be paid from collected securitized utility tariff charges before payments on the securitized utility tariff bonds;

| • |  | the trustee’s lien might not be properly perfected in the collected securitized utility tariff charges prior to or as of the date of Atmos Energy bankruptcy, with the result that the securitized utility tariff bonds would represent only general unsecured claims against Atmos Energy;

| • |  | the bankruptcy court might rule that neither our property interest nor the trustee’s lien extends to securitized utility tariff charges in respect of natural gas consumed after the commencement of Atmos Energy’s bankruptcy case, with the result that the securitized utility tariff bonds would represent only general unsecured claims against Atmos Energy;

| • |  | we and Atmos Energy might be relieved of any obligation to make any payments on the securitized utility tariff bonds during the pendency of the bankruptcy case and might be relieved of any obligation to pay interest accruing after the commencement of the bankruptcy case;

| • |  | Atmos Energy might be able to alter the terms of the securitized utility tariff bonds as part of Atmos Energy’s plan of reorganization;

| • |  | the bankruptcy court might rule that the securitized utility tariff charges should be used to pay, or that we should be charged for, a portion of the cost of providing natural gas service;

| • |  | the bankruptcy court might rule that the remedy provisions of the sale agreement are unenforceable, leaving us with an unsecured claim for actual damages against Atmos Energy that may be difficult to prove or, if proven, to collect in full;

| • |  | if the servicer defaults or enters bankruptcy proceedings, it might be difficult to find a successor servicer and payments on the securitized utility tariff bonds might be suspended;

| • |  | the mere fact of a servicer or seller bankruptcy proceeding might have an adverse effect on the resale market for the securitized utility tariff bonds and on the value of the securitized utility tariff bonds; or

| • |  | the servicer will commingle the securitized utility tariff charges with other revenues it collects, which might obstruct access to the securitized utility tariff charges in case of the bankruptcy of the servicer and reduce the value of your investment in the securitized utility tariff bonds.

The sale of the securitized utility tariff property might be construed as a financing and not a sale in a case of Atmos Energy’s bankruptcy which might delay or limit payments on the securitized utility tariff bonds.

The Securitization Act provides that the characterization of a transfer of securitized utility tariff property as a sale or other absolute transfer will not be affected or impaired by treatment of the transfer as a financing for federal or state tax purposes or financial reporting purposes. We and Atmos Energy will treat the transaction as a sale under applicable law, although for financial reporting and federal and state tax purposes the transaction is intended to be treated as a financing. In the event of a bankruptcy of Atmos Energy, a party in interest in the bankruptcy might assert that the sale of the securitized utility tariff property to us was a financing transaction and not a “sale or other absolute transfer” and that the treatment of the transaction for financial reporting and tax purposes as a financing and not a sale lends weight to that position. If a court were to characterize the transaction as a financing, we expect that we would, on behalf of ourselves and the trustee, be treated as a secured creditor of Atmos Energy in the bankruptcy proceedings, although a court might determine that we only have an unsecured claim against Atmos Energy. See “—The servicer will commingle the securitized utility tariff charges with other revenues it collects, which might obstruct access to the securitized utility tariff charges in case of the servicer’s bankruptcy and reduce the value of your investment in the securitized utility tariff bonds” above. Even if we had a security interest in the securitized utility tariff property, we might not have access to the related securitized utility tariff charge collections during the bankruptcy and would be subject to the risks of a secured creditor in a bankruptcy case, including the possible bankruptcy risks described in the immediately preceding risk factor. As a result, repayment of the securitized utility tariff bonds might be significantly delayed and a plan of reorganization in the bankruptcy might permanently modify the amount and timing of payments to us of the securitized utility tariff charge collections and therefore the amount and timing of funds available to us to pay securitized utility tariff bondholders.

If the servicer enters bankruptcy proceedings, the remittance of certain securitized utility tariff charges by the servicer prior to the date of bankruptcy might constitute preferences, which means these funds might be unavailable to pay amounts owed on the securitized utility tariff bonds.

In the event of a bankruptcy of the servicer, a party in interest might take the position that the remittance of funds prior to bankruptcy of the servicer, pursuant to the servicing agreement, constitutes a preference under bankruptcy law if the remittance of those funds was deemed to be paid on account of a preexisting debt. If a court were to hold that the remittance of funds constitutes a preference, any such remittance within 90 days of the filing of the bankruptcy petition could be avoidable, and the funds could be required to be returned to the bankruptcy estate of the servicer. To the extent that securitized utility tariff charges have been commingled with the general funds of the servicer, the risk that a court would hold that a remittance of funds was a preference would increase. Also, if we are considered to be an “insider” of the servicer, any such remittance made within one year of the filing of the bankruptcy petition could be avoidable as well if the court were to hold that such remittance constitutes a preference. In either case, we or the trustee would merely be an unsecured creditor of the servicer. If any funds were required to be returned to the bankruptcy estate of the servicer, we would expect that the amount of any future securitized utility tariff charges would be increased through the true-up mechanism to recover such amount, though this would not eliminate the risk of payment delays or losses on your investment in the securitized utility tariff bonds.

Claims against Atmos Energy might be limited in the event of its bankruptcy.

If the seller, Atmos Energy, were to become a debtor in a bankruptcy case, claims, including indemnity claims, by us against the seller under the sale agreement and the other documents executed in connection with the sale agreement could be unsecured claims and would be disposed of in the bankruptcy case. In addition, the bankruptcy court might estimate any contingent claims that we have against Atmos Energy and, if it determines that the contingency giving rise to these claims is unlikely to occur, estimate the claims at a lower amount. A

26

##### Table of Contents

party in interest in the bankruptcy of Atmos Energy might challenge the enforceability of the indemnity provisions in the sale agreement. If a court were to hold that the indemnity provisions were unenforceable, we would be left with a claim for actual damages against Atmos Energy based on breach of contract principles, which would be subject to estimation and/or calculation by the court. We cannot give any assurance as to the result if any of the above-described actions or claims were made. Furthermore, we cannot give any assurance as to what percentage of their claims, if any, unsecured creditors would receive in any bankruptcy proceeding involving Atmos Energy.

The bankruptcy of Atmos Energy might limit the remedies available to the trustee.

Upon an event of default for the securitized utility tariff bonds under the Indenture, the Securitization Act permits the trustee to enforce the security interest in the securitized utility tariff property in accordance with the terms of the Indenture. In this capacity, the trustee is permitted to request the Kansas commission or a court of appropriate jurisdiction for an order of sequestration and payment to all securitized utility tariff bondholders of all revenues arising with respect to the related securitized utility tariff property. There can be no assurance, however, that the Kansas commission or such court would issue this order after a Atmos Energy bankruptcy in light of the automatic stay provisions of Section 362 of the United States Bankruptcy Code. In that event, the trustee would be required to seek an order from the bankruptcy court lifting the automatic stay to permit this action by the Kansas court, and an order requiring an accounting and segregation of the revenues arising from the securitized utility tariff property. There can be no assurance that a court would grant either order.

Other risks associated with an investment in the securitized utility tariff bonds

Atmos Energy’s indemnification obligations under the sale agreement and the servicing agreement are limited and might not be sufficient to protect your investment in the securitized utility tariff bonds.

Atmos Energy is obligated under the sale agreement to indemnify us and the trustee, for itself and on behalf of the securitized utility tariff bondholders, only in specified circumstances and will not be obligated to repurchase any securitized utility tariff property in the event of a breach of any of its representations, warranties or covenants regarding the securitized utility tariff property. Similarly, Atmos Energy is obligated under the servicing agreement to indemnify us and the trustee, for itself and on behalf of the securitized utility tariff bondholders only in specified circumstances. Please read “THE SALE AGREEMENT” and “THE SERVICING AGREEMENT” in this prospectus.

Neither the trustee nor the securitized utility tariff bondholders will have the right to accelerate payments on the securitized utility tariff bonds as a result of a breach under the sale agreement or servicing agreement, absent an event of default under the Indenture governing the securitized utility tariff bonds as described in “DESCRIPTION OF THE SECURITIZED UTILITY TARIFF BONDS—What Constitutes an Event of Default on the Securitized Utility Tariff Bonds.” Furthermore, Atmos Energy might not have sufficient funds available to satisfy its indemnification obligations under these agreements, and the amount of any indemnification paid by Atmos Energy might not be sufficient for you to recover all of your investment in the securitized utility tariff bonds. In addition, if Atmos Energy becomes obligated to indemnify securitized utility tariff bondholders, the ratings on the securitized utility tariff bonds will likely be downgraded as a result of the circumstances causing the breach and the fact that securitized utility tariff bondholders will be unsecured creditors of Atmos Energy with respect to any of these indemnification amounts. Atmos Energy will not indemnify any person for any loss, damages, liability, obligation, claim, action, suit or payment resulting solely from a downgrade in the ratings on the securitized utility tariff bonds, or for any consequential damages, including any loss of market value of the securitized utility tariff bonds resulting from a default or a downgrade of the ratings of the securitized utility tariff bonds. Please read “THE SALE AGREEMENT—Atmos Energy’s Representations and Warranties” and “—Atmos Energy’s Obligation to Indemnify Us and the Trustee and to Take Legal Action” in this prospectus.

##### Table of Contents

If the ratings on the securitized utility tariff bonds are withdrawn or revised, the value of the bonds may be adversely affected.

We expect that the securitized utility tariff bonds will receive credit ratings from two nationally recognized statistical rating organizations (“NRSRO”). A rating is not a recommendation to buy, sell or hold the securitized utility tariff bonds.

The ratings merely analyze the probability that we will repay the total principal amount of the securitized utility tariff bonds at the final maturity date (which is later than the scheduled final payment date) and will make timely interest payments. The ratings are not an indication that the rating agencies believe that principal payments are likely to be paid on time according to the expected sinking fund schedule.

Under Rule 17g-5 of the Exchange Act, NRSROs providing Atmos Energy, as the sponsor, with the requisite certification will have access to all information posted on a website by Atmos Energy for the purpose of determining the initial rating and monitoring the rating after the closing date in respect of the securitized utility tariff bonds. As a result, an NRSRO other than an NRSRO hired by Atmos Energy (the “hired NRSRO”) may issue ratings on the securitized utility tariff bonds (“Unsolicited Ratings”), which may be lower, and could be significantly lower, than the ratings assigned by the hired NRSROs. The Unsolicited Ratings may be issued prior to, or after, the issuance date of the securitized utility tariff bonds. Issuance of any Unsolicited Rating will not affect the issuance of the securitized utility tariff bonds. Issuance of an Unsolicited Rating lower than the ratings assigned by the hired NRSRO on the securitized utility tariff bonds might adversely affect the value of the securitized utility tariff bonds and, for regulated entities, could affect the status of the securitized utility tariff bonds as a legal investment or the capital treatment of the securitized utility tariff bonds. Investors in the securitized utility tariff bonds should consult with their legal counsel regarding the effect of the issuance of a rating by a non-hired NRSRO that is lower than the rating of a hired NRSRO. None of Atmos Energy, us, the underwriter or any of our or their affiliates will have any obligation to inform you of any Unsolicited Ratings assigned after the date of this prospectus. In addition, if we or Atmos Energy fail to make available to a non-hired NRSRO any information provided to any hired rating agency for the purpose of assigning or monitoring the ratings on the securitized utility tariff bonds, a hired NRSRO could withdraw its ratings on the securitized utility tariff bonds, which could adversely affect the market value of the securitized utility tariff bonds and/or limit your ability to resell the securitized utility tariff bonds.

Atmos Energy’s credit ratings might affect the market value of the securitized utility tariff bonds.

Although Atmos Energy is not an obligor on the securitized utility tariff bonds, a downgrading of the credit ratings on the debt of Atmos Energy might have an adverse effect on the market value of the securitized utility tariff bonds. Atmos Energy is rated by S&P Global Ratings, a division of S&P Global Inc. and Moody’s Investors Service, Inc. Credit ratings may change at any time by the rating agencies. A NRSRO has the authority to revise or withdraw its rating based solely upon its own judgment.

The absence of a secondary market for the securitized utility tariff bonds might limit your ability to resell the securitized utility tariff bonds.

The underwriter for the securitized utility tariff bonds might assist in resales of the securitized utility tariff bonds, but it is not required to do so. A secondary market for the securitized utility tariff bonds might not develop. If a secondary market does develop, it might not continue or it might not be sufficiently liquid to allow you to resell any of the securitized utility tariff bonds. We do not anticipate that the securitized utility tariff bonds will be listed on any securities exchange. Please read “PLAN OF DISTRIBUTION” in this prospectus.

You might receive principal payments for the securitized utility tariff bonds later than you expect.

The amount and the rate of collection of the securitized utility tariff charges for the securitized utility tariff bonds, together with the related securitized utility tariff charge adjustments, will generally determine whether there is a delay in the scheduled repayments for the securitized utility tariff bond principal. If the servicer collects

28

##### Table of Contents

the securitized utility tariff charges at a slower rate than expected, it might have to request adjustments of the securitized utility tariff charges. If those adjustments are not timely and accurate, you might experience a delay in payments of principal and interest and a decrease in the value of your investment in the securitized utility tariff bonds. Please read “DESCRIPTION OF THE SECURITIZED UTILITY TARIFF BONDS” in this prospectus.

Atmos Energy may cause the issuance, by another subsidiary or affiliated entity, of additional securitized utility tariff bonds in Kansas secured by additional securitized utility tariff property that includes a nonbypassable charge on retail customers.

Any new issuance of securitized utility tariff bonds by another subsidiary or affiliated entity of Atmos Energy in Kansas may include terms and provisions that would be unique to that particular issuance. In the event a retail customer does not pay in full all amounts owed under any bill, including securitized utility tariff charges, Atmos Energy, as servicer, is required to allocate any resulting shortfalls in securitized utility tariff charges ratably based on the amounts of securitized utility tariff charges owed in respect of the securitized utility tariff bonds, and amounts owed in respect of other securitized utility tariff bonds. However, if a dispute arises with respect to the allocation of such securitized utility tariff charges or other delays occur on account of the administrative burdens of making such allocation, we cannot assure you that any issuance of other securitized utility tariff bonds by another subsidiary or affiliated entity of Atmos Energy in Kansas would not cause reductions or delays in payment of principal and interest on the securitized utility tariff bonds.

If the investment of collected securitized utility tariff charges and other funds held by the trustee in the collection account results in investment losses or the investments become illiquid, you may receive payment of principal and interest on the securitized utility tariff bonds later than you expect.

Funds held by the trustee in the collection account will be invested in eligible investments at the written direction of the servicer. Eligible investments include commercial paper, money market funds and repurchase obligations with respect to United States treasuries, among other items. Although the eligible investments as defined in the Indenture governing the securitized utility tariff bonds have traditionally been viewed as highly liquid with a low probability of loss, illiquidity and losses have been experienced by investors in certain eligible investments as a result of disruptions in the financial markets in recent years. If investment losses or illiquidity is experienced, you might experience a delay in payments of principal and interest on the securitized utility tariff bonds and a decrease in the value of your investment in the securitized utility tariff bonds.

A deterioration in economic conditions could adversely affect Atmos Energy’s retail customers which could adversely affect the billing and collection of securitized utility tariff charges.

Any adverse changes in economic conditions could adversely affect the financial resources of many of Atmos Energy’s retail customers. As a result, Atmos Energy’s retail customers could seek to use less gas and it may be more difficult for them to pay their gas bills. This would likely lead to slower collections and increased risk of nonpayment by retail customers. Additionally, should economic conditions deteriorate, Atmos Energy’s industrial customers could seek alternative energy sources. This could reduce Atmos Energy’s retail customer count, resulting in higher securitized utility tariff charges for Atmos Energy’s remaining retail customers. This, in turn, could adversely impact the billing and collection of securitized utility tariff charges, thereby increasing the risk of nonpayment by retail customers.

Regulatory provisions affecting certain investors could adversely affect the liquidity and the regulatory treatment of investments in the securitized utility tariff bonds.

European Union (“EU”) legislation comprising Regulation (EU) 2017/2402 (as amended, the “EU Securitization Regulation”) and certain related regulatory technical standards, implementing technical standards and official guidance (together, the “European Securitization Rules”) imposes certain restrictions and obligations with regard to securitizations (as such term is defined for purposes of the EU Securitization Regulation). The

29

##### Table of Contents

European Securitization Rules are in force throughout the EU (and are expected also to be implemented in the non-EU member states of the European Economic Area).

Pursuant to the European Securitization Rules, EU Institutional Investors investing in a securitisation (as so defined) must, amongst other things, verify that (a) certain credit-granting requirements are satisfied, (b) the originator, sponsor or original lender retains on an ongoing basis a material net economic interest which, in any event, shall not be less than 5%, determined in accordance with Article 6 of the EU Securitization Regulation, and discloses that risk retention, (c) the originator, sponsor or relevant securitization special purpose entity has, where applicable, made available information as required by Article 7 of the EU Securitization Regulation and (d) they have carried out a due-diligence assessment that enables the EU Institutional Investors to assess the risks involved, considering at least (i) the risk characteristics of the securitisation position and the underlying exposures and (ii) all the structural features of the securitization that can materially impact the performance of the securitisation position.

EU Institutional Investors include: (a) insurance undertakings and reinsurance undertakings as defined in Directive 2009/138/EC, as amended, (b) institutions for occupational retirement provision falling within the scope of Directive (EU) 2016/2341 (subject to certain exceptions), and certain investment managers and authorized entities appointed by such institutions, (c) alternative investment fund managers as defined in Directive 2011/61/EU which manage and/or market alternative investment funds in the EU, (d) certain internally managed investment companies authorized in accordance with Directive 2009/65/EC, and managing companies as defined in that Directive, (e) credit institutions as defined in Regulation (EU) No 575/2013 (CRR) (and certain consolidated affiliates thereof); and (f) investment firms as defined in CRR (and certain consolidated affiliates thereof).

With respect to the United Kingdom (UK), relevant UK-established or UK-regulated persons (as described below) are subject to the restrictions and obligations of the EU Securitization Regulation as it forms part of UK domestic law by operation of the European Union (Withdrawal) Act 2018 (as amended, the “EUWA”), and as amended by the Securitisation (Amendment) (EU Exit) Regulations 2019, and as further amended from time to time, the UK Securitization Regulation. The UK Securitization Regulation, together with (a) all applicable binding technical standards made under the UK Securitization Regulation, (b) any EU regulatory technical standards or implementing technical standards relating to the EU Securitization Regulation (including such regulatory technical standards or implementing technical standards that are applicable pursuant to any transitional provisions of the EU Securitization Regulation) forming part of UK domestic law by operation of the EUWA, (c) all relevant guidance, policy statements or directions relating to the application of the UK Securitization Regulation (or any binding technical standards) published by the Financial Conduct Authority (the “FCA”) and/or the Prudential Regulation Authority (the “PRA”) (or their successors), (d) any guidelines relating to the application of the EU Securitization Regulation that are applicable in the UK, (e) any other transitional, saving or other provision relevant to the UK Securitization Regulation by virtue of the operation of the EUWA and (f) any other applicable laws, acts, statutory instruments, rules, guidance or policy statements published or enacted relating to the UK Securitization Regulation, in each case, as may be further amended, supplemented or replaced, from time to time, are referred to in this prospectus as the UK Securitization Rules.

Article 5 of the UK Securitization Regulation places certain conditions on investments in a “securitisation” (as defined in the UK Securitization Regulation) by a UK Institutional Investor. UK Institutional Investors include: (a) an insurance undertaking as defined in section 417(1) of the Financial Services And Markets Act 2000 (as amended, the “FSMA”), (b) a reinsurance undertaking as defined in section 417(1) of the FSMA, (c) an occupational pension scheme as defined in section 1(1) of the Pension Schemes Act 1993 that has its main administration in the UK, or a fund manager of such a scheme appointed under section 34(2) of the Pensions Act 1995 that, in respect of activity undertaken pursuant to that appointment, is authorized for the purposes of section 31 of the FSMA, (d) an alternative investment fund manager as defined in regulation 4(1) of the Alternative Investment Fund Managers Regulation 2013 that markets or manages alternative investments funds (as defined in regulation 3 of the Alternative Investment Fund Managers Regulation 2013) in the UK, (e) a

30

##### Table of Contents

management company as defined in section 237(2) of the FSMA, (f) an undertaking for collective investment in transferable securities as defined by section 236A of the FSMA, which is an authorized open ended investment company as defined in section 237(3) of the FSMA, and (g) a CRR firm as defined in Regulation (EU) No 575/2013, as it forms part of UK domestic law by virtue of the EUWA (and certain consolidated affiliates thereof).

Prior to investing in (or otherwise holding an exposure to) a “securitisation position” (as defined in the UK Securitization Regulation), a UK Institutional Investor, other than the originator, sponsor or original lender (each as defined in the UK Securitization Regulation), must, among other things: (a) verify that, where the originator or original lender is established in a third country (i.e. not within the UK), the originator or original lender grants all the credits giving rise to the underlying exposures on the basis of sound and well-defined criteria and clearly established processes for approving, amending, renewing and financing those credits and has effective systems in place to apply those criteria and processes to ensure that credit granting is based on a thorough assessment of the obligor’s creditworthiness, (b) verify that, if established in the third country (i.e. not within the UK), the originator, sponsor or original lender retains on an ongoing basis a material net economic interest that, in any event, shall not be less than 5%, determined in accordance with Article 6 of the UK Securitization Regulation, and discloses the risk retention to the affected investors, (c) verify that, where established in a third country (i.e. not within the UK), the originator, sponsor or relevant securitization special purpose entity, where applicable, made available information that is substantially the same as that which it would have made available under Article 7 of the UK Securitization Regulation (which sets out certain transparency requirements) if it had been established in the UK and has done so with such frequency and modalities as are substantially the same as those with which it would have made information available if it had been established in the UK, and (d) carry out a due-diligence assessment that enables the UK Institutional Investors to assess the risks involved, considering at least (i) the risk characteristics of the securitisation position and the underlying exposures and (ii) all the structural features of the securitization that can materially impact the performance of the securitisation position.

We and Atmos Energy do not believe that the securitized utility tariff bonds fall within the definition of a “securitization” for purposes of the EU Securitization Regulation or the UK Securitization Regulation as there is no tranching of credit risk associated with exposures under the transactions described in this prospectus. Therefore, we and Atmos Energy believe such transactions are not subject to the European Securitization Rules or the UK Securitization Rules. As such, neither we nor Atmos Energy, nor any other party to the transactions described in this prospectus, intend, or are required under the transaction documents, to retain a material net economic interest in respect of such transactions, or to take, or to refrain from taking, any other action, in a manner prescribed or contemplated by the European Securitization Rules or the UK Securitization Rules. In particular, no such Person undertakes to take, or to refrain from taking, any action for purposes of compliance by any investor (or any other Person) with any requirement of the European Securitization Rules or the UK Securitization Rules to which such investor (or other Person) may be subject at any time.

However, if a competent authority were to take a contrary view and determine that the transactions described in this prospectus do constitute a securitization for purposes of the EU Securitization Regulation or the UK Securitization Regulation, then any failure by an EU Institutional Investor or a UK Institutional Investor (as applicable) to comply with any applicable European Securitization Rules or UK Securitization Rules (as applicable) with respect to an investment in the securitized utility tariff bonds may result in the imposition of a penalty regulatory capital charge on that investment or of other regulatory sanctions and remedial measures.

Consequently, the securitized utility tariff bonds may not be a suitable investment for EU Institutional Investors or UK Institutional Investors. As a result, the price and liquidity of the securitized utility tariff bonds in the secondary market may be adversely affected.

Prospective investors are responsible for analyzing their own legal and regulatory position and are advised to consult with their own advisors and any relevant regulator or other authority regarding the scope, applicability and compliance requirements of the European Securitization Rules and the UK Securitization Rules, and the

31

suitability of the securitized utility tariff bonds for investment. Neither we nor Atmos Energy, nor any other party to the transactions described in this prospectus, make any representation as to any such matter, or have any liability to any investor (or any other Person) for any non-compliance by any such Person with the European Securitization Rules, the UK Securitization Rules or any other applicable legal, regulatory or other requirements.

REVIEW OF SECURITIZED UTILITY TARIFF PROPERTY

Pursuant to the rules of the SEC, Atmos Energy, as sponsor, has performed, as described below, a review of the securitized utility tariff property underlying the securitized utility tariff bonds. As required by these rules, the review was designed and effected to provide reasonable assurance that disclosure regarding the securitized utility tariff property is accurate in all material respects. Atmos Energy did not engage a third party in conducting its review.

The securitized utility tariff bonds will be secured under the Indenture by the Indenture’s trust estate. The principal asset of the Indenture’s trust estate is the securitized utility tariff property. The securitized utility tariff property is a present contract right authorized and created pursuant to the securitization provisions of the Securitization Act and an irrevocable financing order. The securitized utility tariff property includes the irrevocable right to impose, bill, charge, collect and receive nonbypassable securitized utility tariff charges in amounts sufficient to timely pay scheduled principal and interest and ongoing financing costs in connection with the securitized utility tariff bonds. The securitized utility tariff charges are nonbypassable charges that will be paid by all existing and future retail customers receiving natural gas service from Atmos Energy or its successors or assignees under the rate schedules or special contracts approved by the Kansas commission, even if a retail customer elects to purchase natural gas from an alternative natural gas supplier following a fundamental change in regulation of public utilities in Kansas; provided, however, if a customer disconnects from Atmos Energy’s gas distribution system and ceases to purchase natural gas by switching to an alternative source of energy that meets all of its energy needs, such customer would no longer be a retail customer and would not be subject to paying securitized utility tariff charges. During the 12 months ended September 30, 2022, approximately 68% of Atmos Energy’s total gas deliveries were to residential retail customers and approximately 32% were to non-residential retail customers.

The securitized utility tariff property is not a static pool of receivables or assets. Securitized utility tariff charges authorized in the financing order are irrevocable and not subject to reduction, impairment, or adjustment by further action of the Kansas commission except that securitized utility tariff charges are subject to semi-annual and other interim true-up adjustments to correct any over-collections or under-collections of securitized utility tariff charges during the previous six months and to ensure the expected recovery of amounts sufficient to timely provide all payments of debt service and other required amounts and charges in connection with the securitized utility tariff bonds. All revenues and collections resulting from securitized utility tariff charges provided for in the financing order are part of the securitized utility tariff property. The securitized utility tariff charges will be calculated on a fixed monthly charge per retail customer. The securitized utility tariff property is described in more detail under “DESCRIPTION OF THE SECURITIZED UTILITY TARIFF PROPERTY” in this prospectus.

In the financing order, the Kansas commission, among other things:

| • |  | orders that Atmos Energy, as servicer, shall impose and collect from all Atmos Energy retail customers the securitized utility tariff charges that are nonbypassable in an amount calculated as provided in the financing order;

| • |  | orders that upon the transfer of the securitized utility tariff property to us by Atmos Energy, we shall be the owner of the rights to the securitized utility tariff property and that Atmos Energy as servicer is merely the collection agent for us; and

| • |  | pledges that it will act under the financing order as expressly authorized by the securitization provisions of the Securitization Act to ensure the projected recovery of securitized utility tariff charge revenues are sufficient to provide timely payment of the scheduled principal of and interest on the securitized utility tariff bonds.

Please read “THE SECURITIZATION ACT” and “ATMOS ENERGY’S FINANCING ORDER” in this prospectus for more information.

The characteristics of securitized utility tariff property are unlike the characteristics of assets underlying mortgage and other commercial asset securitizations because securitized utility tariff property is a creature of statute and state regulatory commission proceedings. Because the nature and characteristics of the securitized

##### Table of Contents

utility tariff property and many elements of the securitized utility tariff bond securitization are set forth and constrained by the securitization provisions of the Securitization Act, Atmos Energy, as sponsor, does not select the assets to be securitized in ways common to many securitizations. Moreover, the securitized utility tariff bonds do not contain origination or underwriting elements similar to typical mortgage or other loan transactions involved in other forms of asset-backed securities. The securitization provisions of the Securitization Act and the Kansas commission require the imposition on, and collection of securitized utility tariff charges from, existing and future retail customers receiving natural gas service from Atmos Energy or it successors or assignees under Kansas commission-approved rate schedules or under special contracts, even if a retail customer elects to purchase natural gas from an alternative natural gas supplier following a fundamental change in regulation of public utilities in Kansas subject to certain exceptions discussed elsewhere in this prospectus. Since the securitized utility tariff charges are assessed against all retail customers and the true-up adjustment mechanism adjusts for the impact of retail customer defaults, the collectability of the securitized utility tariff charges is not ultimately dependent upon the credit quality of particular Atmos Energy retail customers, as would be the case in the absence of the true-up adjustment mechanism.

The review by Atmos Energy of the securitized utility tariff property underlying the securitized utility tariff bonds has involved a number of discrete steps and elements as described in more detail below. First, Atmos Energy has analyzed and applied the securitization provisions of the Securitization Act’s requirements for securitization of qualified extraordinary costs in seeking approval of the Kansas commission for the issuance of the financing order and in its application for a financing order with respect to the characteristics of the securitized utility tariff property to be created pursuant to the financing order. Atmos Energy worked with its counsel in preparing the application for a financing order and with the Kansas commission on the terms of the financing order. Moreover, Atmos Energy worked with its counsel, its structuring agent and counsel to the underwriter in preparing the legal agreements that provide for the terms of the securitized utility tariff bonds and the security for the securitized utility tariff bonds. Atmos Energy has analyzed economic issues and practical issues for the scheduled payment of the securitized utility tariff bonds in terms of impacts of economic factors, potentials for disruptions due to weather or catastrophic events and its own forecasts for retail customer growth as well as the historic accuracy of its prior forecasts.

In light of the unique nature of the securitized utility tariff property, Atmos Energy has taken (or prior to the offering of the securitized utility tariff bonds, will take) the following actions in connection with its review of the securitized utility tariff property and the preparation of the disclosure for inclusion in this prospectus describing the securitized utility tariff property, the securitized utility tariff bonds and the proposed securitization:

| • |  | reviewed the securitization provisions of the Securitization Act, the rules and regulations of the Kansas commission as they relate to the securitized utility tariff property in connection with the preparation and filing of the application with the Kansas commission for the approval of the financing order in order to confirm that the application and proposed financing order satisfied applicable statutory and regulatory requirements;

| • |  | actively participated in the proceeding before the Kansas commission relating to the approval of the requested financing order;

| • |  | compared the financing order, as issued by the Kansas commission, to the securitization provisions of the Securitization Act and the rules and regulations of the Kansas commission as they relate to the securitized utility tariff property to confirm that the financing order met such requirements;

| • |  | compared the proposed terms of the securitized utility tariff bonds to the applicable requirements in the securitization provisions of the Securitization Act, the financing order and the regulations of the Kansas commission to confirm that they met such requirements;

| • |  | prepared and reviewed the agreements to be entered into in connection with the issuance of the securitized utility tariff bonds and compared such agreements to the applicable requirements in the securitization provisions of the Securitization Act, the financing order and the regulations of the Kansas commission to confirm that they met such requirements;

34

##### Table of Contents

| • |  | reviewed the disclosure in this prospectus regarding the securitization provisions of the Securitization Act, the financing order and the agreements to be entered into in connection with the issuance of the securitized utility tariff bonds, and compared such descriptions to the relevant securitization provisions of the Securitization Act, the financing order and such agreements to confirm the accuracy of such descriptions;

| • |  | consulted with legal counsel to assess if there is a basis upon which the securitized utility tariff bondholders (or the trustee acting on their behalf) could successfully challenge the constitutionality of any legislative action by the State of Kansas (including the Kansas commission) that could repeal or amend the securitization provisions of the Securitization Act that could substantially impair the value of the securitized utility tariff property, or substantially reduce, alter or impair the securitized utility tariff charges;

| • |  | reviewed the process and procedures in place for it, as servicer, to perform its obligations under the servicing agreement, including without limitation, billing and collecting the securitized utility tariff charges to be provided for under the securitized utility tariff property, forecasting securitized utility tariff charge revenues, preparing and filing applications for true-up adjustments to the securitized utility tariff charges and enforcing credit standards;

| • |  | reviewed the methodology and procedure of the true-up mechanism for adjusting securitized utility tariff charge levels to meet the scheduled payments on the securitized utility tariff bonds; and

| • |  | with the assistance of its structuring agent and the underwriter, prepared financial models in order to set the initial securitized utility tariff charges to be provided for under the securitized utility tariff property at a level sufficient to pay on a timely basis scheduled principal and interest on the securitized utility tariff bonds.

In connection with the preparation of such models, Atmos Energy:

| • |  | reviewed (i) the historical natural gas usage and retail customer growth within Atmos Energy’s retail customer base and (ii) forecasts of expected sales and retail customer growth; and

| • |  | analyzed the sensitivity of the weighted average life of the securitized utility tariff bonds in relation to variances in actual retail customer count from forecasted levels and in relation to the true-up mechanism in order to assess the probability that the weighted average life of the securitized utility tariff bonds may be extended as a result of such variances, and in the context of the operation of the true-up mechanism for adjustment of securitized utility tariff charges to address under- or over-collections in light of scheduled payments on the securitized utility tariff bonds.

As a result of this review, Atmos Energy has concluded that:

| • |  | the securitized utility tariff property, the financing order and the agreements to be entered into in connection with the issuance of the securitized utility tariff bonds meet in all material respects the applicable statutory and regulatory requirements;

| • |  | the disclosure in this prospectus regarding the securitization provisions of the Securitization Act, the financing order and the agreements to be entered into in connection with the issuance of the securitized utility tariff bonds is as of its date, accurate in all material respects;

| • |  | the servicer has adequate processes and procedures in place to perform its obligations under the servicing agreement;

| • |  | securitized utility tariff charge revenues, as adjusted from time to time as provided in the securitization provisions of the Securitization Act and the financing order, are expected to be sufficient to pay on a timely basis scheduled principal and interest on the securitized utility tariff bonds; and

| • |  | the design and scope of Atmos Energy’s review of the securitized utility tariff property as described above is effective to provide reasonable assurance that the disclosure regarding the securitized utility tariff property in this prospectus is accurate in all material respects.

DESCRIPTION OF THE SECURITIZED UTILITY TARIFF PROPERTY

Creation of Securitized Utility Tariff Property; Financing Order

The Securitization Act defines securitized utility tariff property as, “All rights and interests of a public utility, its successor or assignee under a financing order, including the right to impose, bill, charge, collect and receive securitized utility tariff charges authorized under the financing order and to obtain periodic adjustments to such charges authorized under this section and as provided in the financing order; and all revenues, collections, claims, rights to payments, payments, money or proceeds arising from the rights and interests specified in the financing order, regardless of whether such revenues, collections, claims, rights to payment, payments, money or proceeds are imposed, billed, received, collected or maintained together with or commingled with other revenues, collections, rights to payment, payments, money or proceeds.” The securitized utility tariff bonds will be secured by the securitized utility tariff property, as well as the other collateral described under “DESCRIPTION OF THE SECURITIZED UTILITY TARIFF BONDS—The Security for the Securitized Utility Tariff Bonds.”

In addition to the right to impose, bill, charge, collect and receive securitized utility tariff charges, the financing order:

| • |  | Authorizes the transfer of the securitized utility tariff property to us and the issuance of securitized utility tariff bonds;

| • |  | Establishes procedures for periodic true-up adjustments to securitized utility tariff charges in the event of over-collection or under-collection; and

| • |  | Provides and pledges that after the earlier of the transfer of the securitized utility tariff property to an assignee or the issuance of the securitized utility tariff bonds authorized by the financing order, the financing order is irrevocable and may not be amended, modified, or terminated by any subsequent action of the Kansas commission.

A form of issuance advice letter and a form of tariff (called the “Winter Event Securitized Cost Recovery Rider” or “WESCR”) are attached to the financing order. We will complete and file both documents with the Kansas commission immediately after the pricing of the securitized utility tariff bonds. The issuance advice letter confirms to the Kansas commission the interest rate and expected sinking fund schedule for the securitized utility tariff bonds and sets forth the actual dollar amount of the initial securitized utility tariff charges as described below under “ATMOS ENERGY’S FINANCING ORDER—Issuance Advice Letter.” The Kansas commission’s review of the issuance advice letter will be limited to determining that the final structuring, terms and pricing of the securitized utility tariff bonds are consistent with the criteria established in the financing order and that the mathematical calculations are accurate.

Tariff; Securitized Utility Tariff Charges

The tariff establishes the initial securitized utility tariff charges. It also implements the procedures for periodic adjustments to the securitized utility tariff charges, the payment of securitized utility tariff charges and the semi-annual procedures allowing Atmos Energy as servicer to reconcile the amount of securitized utility tariff charge remittances with the periodic payment requirement.

The securitized utility tariff charges will be payable by all existing or future retail customers receiving natural gas service from Atmos Energy or its successors or assignees under Kansas commission-approved rate schedules or under special contracts, even if a retail customer elects to purchase natural gas from an alternative natural gas supplier following a fundamental change in regulation of public utilities in Kansas.

For purposes of billing securitized utility tariff charges, each retail customer will be designated as a customer belonging to one of the securitized utility tariff charge retail customer classes set forth below. Under

36

##### Table of Contents

the terms of the financing order, Atmos Energy will allocate the securitized utility tariff charges among the securitized utility tariff charge retail customer classes based on the percentage of the total estimated February 2021 sales volumes, as follows:

Securitized Utility Tariff Charge Retail Customer Classes

Retail Customer Class |  | Estimate of February 2021 Usage (Mcf) |  |  | Allocation Percentage |
Residential: |  |  | 23,505,675 |  |  |  | 75.015% |
Non-residential: |  |  |  |  |  |  |  |
Commercial/Public Authority |  |  | 7,572,483 |  |  |  | 24.167% |
School Sales Service |  |  | 82,668 |  |  |  | 0.264% |
Industrial Sales Service |  |  | 50,073 |  |  |  | 0.160% |
Small Generator |  |  | 31 |  |  |  | 0.000% |
Irrigation Engine |  |  | 123,509 |  |  |  | 0.394% |
TOTAL |  |  | 31,334,439 |  |  |  | 100.000% |

The nonbypassable charge applicable to each securitized utility tariff charge retail customer class for any period will be determined based on the allocation percentage of such class, the amount necessary to make payments on the securitized utility tariff bonds for the related period, and as set forth in the Winter Event Securitized Cost Recovery Rider, contained in the form of tariff, attached to the financing order as Appendix B. Securitized utility tariff charges will be calculated on a fixed monthly charge per retail customer, which will be adjusted semi-annually pursuant to the true-up adjustment methodology approved in the financing order. The per retail customer charge will initially be calculated using the retail customer count reported in the most recent Atmos Energy Annual Report filed with the Kansas commission and will be updated semi-annually. The true-up adjustment methodology approved in the financing order is cross collateralized across retail customer classes and requires that any delinquencies or under-collections in one retail customer class will be taken into account in the application of the true-up mechanism to adjust the securitized utility tariff charges for all retail customers, not just the class of retail customers from which the delinquency or under-collection arose.

The securitized utility tariff charges will be reflected as a separate line item on retail customers’ bills and identified as “Winter Event Securitized Cost.” These securitized utility tariff charges will be adjusted semi-annually, or more frequently under certain circumstances, by the servicer in accordance with its filings with the Kansas commission.

Atmos Energy estimates that on an annualized basis the initial securitized utility tariff charges would represent approximately 7% of the total bill received by an average residential customer based on rates as of March 31, 2023.

Billing and Collection Terms and Conditions

Generally, bills are rendered monthly to all customers and are payable within 28 days from mailing for residential customers and within 28 days of mailing for nonresidential customers. Billing will begin with the first cycle of the month following the issuance of the securitized utility tariff bonds. Customers are billed in established cycles, with the total number of days between meter readings generally ranging from 28 to 32 days.

Atmos Energy, as the initial servicer of the securitized utility tariff property will bill and collect the securitized utility tariff charges as described in the servicing agreement, and remit those amounts to the trustee on our behalf. We are a Delaware limited liability company subsidiary special purpose entity created by Atmos Energy to facilitate the securitization. The servicer will perform these functions for us in accordance with the

37

##### Table of Contents

servicing agreement by and between Atmos Energy, as the initial servicer, and us. If the servicer defaults on its obligations under the servicing agreement, the trustee may appoint a successor servicer, subject to the terms and conditions of the servicing agreement.

The securitized utility tariff bonds will be issued pursuant to an indenture and series supplement administered by the trustee. The Indenture will include provisions for a collection account and subaccounts for the collection and administration of the securitized utility tariff charges and payment or funding of the principal and interest on the securitized utility tariff bonds and other costs. We will establish a collection account as a trust account to be held by the trustee as collateral for the payment of the scheduled principal, interest, and other costs approved in the financing order. The collection account will include the general subaccount, the capital subaccount, and the excess funds subaccount, and may include other subaccounts. The servicer will remit securitized utility tariff charges to the trustee, which will deposit such remittances into a general subaccount. Upon issuance of the securitized utility tariff bonds, Atmos Energy will make a capital contribution to us and we will deposit such contribution into a capital subaccount. The capital subaccount will serve as collateral for timely payments of principal and interest on the securitized utility tariff bonds. An excess funds subaccount will hold any securitized utility tariff charge remittances and investment earnings on the collection account (other than earnings attributable to the capital subaccount and released under the terms of the Indenture) in excess of the amounts needed to pay principal and interest on the securitized utility tariff bonds and to pay ongoing costs related to the securitized utility tariff bonds (including replenishing the capital subaccount). Any balance in or allocated to the excess funds subaccount on a true-up adjustment date will be subtracted from the payments to be made on the next payment date for purposes of the true-up adjustment. The servicer is required to make semi-annual adjustments to the securitized utility tariff charges to correct any under-collection or over-collection of securitized utility tariff charges during the preceding six months and ensure the expected recovery of amounts sufficient to timely provide all payments of debt service and other required amounts and charges in connection with the securitized utility tariff bonds. If remitted securitized utility tariff charges are insufficient to make payments of principal and interest on the securitized utility tariff bonds and other components of the periodic payment requirement, then the excess funds subaccount, and the capital subaccount will be drawn down, in that order, to make those payments. The servicer may perform periodic true-ups as necessary to ensure that the amount collected from securitized utility tariff charges is sufficient to service the securitized utility tariff bonds. Within the 30-day period that follows the scheduled payment date that is one year prior to the scheduled final payment date and quarterly thereafter, there will be quarterly true-up adjustments for the securitized utility tariff bonds that remain outstanding.

The obligation to pay securitized utility tariff charges is not subject to any right of set-off, counterclaim or surcharge in connection with the bankruptcy or insolvency of Atmos Energy or any other entity. Securitized utility tariff charges are “nonbypassable” in accordance with the provisions set forth in the Securitization Act and the financing order.

THE SECURITIZATION ACT

Overview

In April 2021, the Kansas Legislature established the Securitization Act (a Kansas senate substitute for House Bill 2072 (Volume 40 - Issue 16 - April 22, 2021), as codified at K.S.A. §§ 66-1,240 - 66-1,253), providing for a financing mechanism through which certain utilities can use securitization financing to recover qualified extraordinary costs (as defined in the Securitization Act) resulting from Winter Storm Uri, by issuing securitized utility tariff bonds. Securitized utility tariff bonds must be approved in a financing order issued by the Kansas commission. A Kansas utility subject to the jurisdiction of the Kansas commission must apply to the Kansas commission in order to obtain a financing order under the Securitization Act to authorize the issuance of securitized utility tariff bonds.

In February 2021, Kansas experienced sub-zero temperatures brought by Winter Storm Uri, which led to a significant increase in demand for electricity and natural gas. On February 14, 2021, a State of Disaster Emergency was issued by Kansas Governor Kelly due to expected prolonged low temperatures and the strain on natural gas and utility providers; at the time, wholesale natural gas prices were reflecting increases from 10 to 100 times their normal rates. On February 15, 2021, the Kansas commission issued an Emergency Order in Docket No. 21-GIMX-303-MIS (Docket 21-303), directing jurisdictional natural gas utilities to coordinate efforts and take all reasonably feasible, lawful, and appropriate actions to ensure adequate transportation of natural gas to interconnected, non-jurisdictional Kansas utilities. Jurisdictional natural gas utilities were ordered to do everything necessary to ensure that natural gas service continued to be provided to their customers in Kansas. The Kansas commission authorized every jurisdictional natural gas distribution utility to defer extraordinary costs incurred during the Winter Event to a regulatory asset account. On May 25, 2022, Atmos Energy applied for a financing order under the Securitization Act, which was issued by the Kansas commission on October 25, 2022.

Under the Securitization Act and the financing order, Atmos Energy retail customers will pay securitized utility tariff charges, which are nonbypassable charges included in their monthly charges. Securitized utility tariff charges will fund payments of principal and interest on the securitized utility tariff bonds, together with related financing costs. Securitized utility tariff charges will be collected by Atmos Energy, as initial servicer, or its successor, as provided for in the financing order and servicing agreement. Pursuant to the financing order, securitized utility tariff charges are required to be adjusted at least semi-annually, and more frequently as necessary, to ensure the recovery of amounts sufficient to timely provide all payment of the scheduled principal, interest and other required amounts in connection with the securitized utility tariff bonds during the preceding six-month period.

Atmos Energy May Securitize Qualified Extraordinary Costs and Related Upfront and Ongoing Financing Costs

Atmos May Issue Securitized Utility Tariff Bonds to Recover Atmos Energy’s Qualified Extraordinary Costs.

Under the Securitization Act, the Kansas commission may issue financing orders approving the issuance of securitized utility tariff bonds to recover certain costs of a natural gas utility, including qualified extraordinary costs and related upfront and ongoing financing costs. A utility, its successors or an assignee of a utility may issue securitized utility tariff bonds. The Securitization Act requires the proceeds of the securitized utility tariff bonds to be used for the purposes of recovering or financing qualified extraordinary costs and related upfront and ongoing costs, as determined by the Kansas commission. Securitized utility tariff bonds are secured by or payable from securitized utility tariff property, which includes the right to impose, bill, charge, collect and receive securitized utility tariff charges, to obtain periodic adjustments to such charges as provided in the financing order and all revenues, collections, claims, rights to payments, payments, money or proceeds arising from the foregoing rights and interests. Under the financing order, the securitized utility tariff bonds may have a legal maximum maturity of 32 years from the issuance date of the bonds.

##### Table of Contents

Securitized utility tariff charges and related financing costs will be allocated to Atmos Energy retail customer classes based on the class percentage of the total estimated February 2021 sales volumes. Securitized utility tariff charges can be imposed only when and to the extent that securitized utility tariff bonds are issued.

The Securitization Act contains a number of provisions designed to facilitate the securitization of qualified extraordinary costs and related upfront and ongoing financing costs.

Creation of Securitized Utility Tariff Property.

The Securitization Act and financing order provide for the creation and establishment of the securitized utility tariff property, which is a present contract right in favor of Atmos Energy, its transferees and other financing parties, to impose, bill, charge, collect and receive securitized utility tariff charges from Atmos Energy’s existing and future retail customers, as well as to obtain periodic adjustments to such charges as provided in the financing order.

A Financing Order is Irrevocable.

A financing order, once effective, together with the securitized utility tariff charges authorized in such financing order, is irrevocable and not subject to amendment, modification or termination by the Kansas commission, except for adjustments pursuant to the Securitization Act in order to correct over-collections or under-collections and to ensure the projected recovery of amounts sufficient to provide timely payment of debt service and all other upfront and ongoing financing costs in connection with the related securitized utility tariff bonds. Although a financing order is irrevocable, the Securitization Act allows for Atmos Energy (or any assignee) to apply for one or more new financing orders to provide for refinancing, retiring and refunding securitized utility tariff bonds upon a showing that statutory criteria are met.

State and Commission Pledges.

The State of Kansas and its agencies, including the Kansas commission, have pledged and agreed with bondholders, the owners of the securitized utility tariff property and other financing parties that, pursuant to the Securitization Act, the state and its agencies will not: (a) alter the statute that authorizes the Kansas commission to create an irrevocable contract right or chose in action by the issuance of a financing order, to create securitized utility tariff property and to make the securitized utility tariff charges imposed by a financing order irrevocable, binding or nonbypassable charges for all existing and future retail customers within the service area of the public utility, (b) take or permit any action that impairs or would impair the value of securitized utility tariff property or the security for the securitized utility tariff bonds, or revises the Securitized Utility Tariff Costs (as defined in the Securitization Act) for which recovery is authorized, (c) impair the rights and remedies of the securitized utility tariff bondholders, assignees and other financing parties in any way, or (d) except for changes made pursuant to the true-up adjustment mechanism expressly allowed by law, reduce, alter, or impair the securitized utility tariff charges to be imposed, billed, charged, collected, and remitted for the benefit of the securitized utility tariff bondholders, any assignee, and any other financing parties, until any and all principal, interest, premium, financing costs and other fees, expenses or charges incurred and any contracts to be performed in connection with the related securitized utility tariff bonds have been paid and performed in full.

The Kansas commission has jurisdiction over Atmos Energy and its application for a financing order to recover qualified extraordinary costs and related financing costs pursuant to K.S.A. § 66-1,241(b).

Constitutional Matters

To date, no federal or Kansas cases addressing the repeal or amendment of the Securitization Act or securitization provisions analogous to those contained in the Securitization Act have been decided. There have been cases in which courts have applied the Contract Clause of the United States Constitution to strike down

40

##### Table of Contents

legislation regarding similar matters, such as legislation reducing or eliminating taxes, public charges or other sources of revenues servicing other types of bonds issued by public instrumentalities or private issuers, or otherwise substantially impairing or eliminating the security for bonds or other indebtedness. Based upon this case law, Sidley Austin LLP, as counsel to Atmos Energy and us, expects to deliver an opinion, prior to the closing of the offering of the securitized utility tariff bonds described in this prospectus, to the effect that, under federal law principles, the State pledge described above unambiguously indicates the State’s intent to be bound with the securitized utility tariff bondholders and, subject to all of the qualifications, limitations and assumptions set forth in its opinion, supports the conclusion that the State pledge constitutes a binding contractual relationship between the State and the securitized utility tariff bondholders for purposes of the Federal Contract Clause and, with regard to Kansas, Husch Blackwell LLP, as Kansas counsel to Atmos Energy and us, expects to deliver an opinion to the effect that when confronted with the question of whether state legislation impairs contractual obligations, it appears the Kansas Supreme Court looks exclusively to Federal Contracts Clause analysis, and therefore Kansas Courts would more likely than not look to the Federal Contract Clause in these circumstances.

Subject to all of the qualifications, limitations and assumptions set forth in each respective opinion, including that any impairment of the contract be “substantial,” the opinion of Sidley Austin LLP is expected to state that a reviewing court of competent jurisdiction would hold that the State of Kansas could not constitutionally repeal or amend the Securitization Act or take any other action contravening the State pledge and creating an impairment (without, as the Securitization Act requires, providing full compensation by law for the full protection of the securitized utility tariff charges to be collected pursuant to the financing order and full protection of the securitized utility tariff bondholders), unless such court would determine that such impairment is a necessary and reasonably tailored exercise of the State of Kansas’ sovereign powers to serve a significant and legitimate public purpose justifying such action.

Sidley Austin LLP, subject to all of the qualifications, limitations and assumptions (including the assumption that any impairment would be “substantial”) set forth in its opinion, is also expected to state in its opinion that the Kansas commission’s pledge (i) constitutes part of the binding contractual obligation of the State of Kansas for purposes of the Federal Contract Clause, and (ii) provides a basis upon which the securitized utility tariff bondholders could challenge successfully any action by the Kansas commission related to the exercise of a legislatively granted power, including the rescission or amendment of the financing order, if that exercise created an impairment, on the same basis as other actions of the State that create an impairment as described above.

In addition, any action of the Kansas legislature adversely affecting the securitized utility tariff property or the ability to collect securitized utility tariff charges may be considered a “taking” under the United States or Kansas Constitutions. Sidley Austin LLP has advised us that it is not aware of any federal, and Husch Blackwell LLP has advised us that it is not aware of any Kansas, court cases addressing the applicability of the Takings Clause of the United States or Kansas Constitution respectively in a situation analogous to that which would be involved in an amendment or repeal of the Securitization Act. It is possible that a court would decline even to apply a Takings Clause analysis to a claim based on an amendment or repeal of the Securitization Act, since, for example, a court might determine that a Contract Clause analysis rather than a Takings Clause analysis should be applied. Assuming a Takings Clause analysis were applied under the United States Constitution or the Kansas Constitution, Sidley Austin LLP and Husch Blackwell LLP respectively expect to render an opinion, prior to the closing of the offering of the securitized utility tariff bonds described in this prospectus, to the effect that, under the existing case law of the respective courts each opinion is covering, a reviewing court of competent jurisdiction would hold (or with respect to the opinion of Husch Blackwell LLP, more likely than not, would hold), subject to all of the qualifications, limitations and assumptions set forth in each respective opinion, if it concludes that the securitized utility tariff property is protected by the Takings Clause of the United States Constitution (or the Takings Clause of the Kansas Constitution with respect to the opinion of Husch Blackwell LLP), that the State would be required to pay just compensation to the securitized utility tariff bondholders, as determined by such court, if the Kansas legislature repealed or amended the Securitization Act or took any other action contravening the State pledge, if the court determines doing so constituted a permanent appropriation of a substantial property interest of the securitized utility tariff bondholders in the securitized utility tariff property or denied all economically productive use of the securitized utility tariff property, destroyed the securitized utility tariff property other than in response to emergency conditions or substantially reduced, altered, limited or impaired the value of the securitized utility tariff property so as to unduly interfere with the reasonable

41

##### Table of Contents

expectations of the Holders arising from their investments in the securitized utility tariff bonds. In examining whether action of the Kansas legislature amounts to a regulatory taking, both federal and state courts will consider the character of the governmental action, the economic impact of the governmental action on the securitized utility tariff bondholders, and the extent to which the governmental action interferes with distinct investment-backed expectations. There is no assurance, however, that, even if a court were to award just compensation, it would be sufficient for you to recover fully your investment in the securitized utility tariff bonds.

In connection with the foregoing, Sidley Austin LLP has advised us that issues relating to the Contract and Takings Clause of the United States Constitution, and Husch Blackwell LLP has advised us that issues relating to the Takings Clause of the Kansas Constitution, are essentially decided on a case-by-case basis and that the courts’ determinations, in most cases, appear to be strongly influenced by the facts and circumstances of the particular case, and has further advised us that there are no reported controlling judicial precedents that are directly on point. The opinions described above will be subject to the qualifications included in them. The degree of impairment necessary to meet the standards for relief under a Takings Clause analysis or Contract Clause analysis could be substantially in excess of what a securitized utility tariff bondholder would consider material.

In addition, Sidley Austin LLP expects to render an opinion, prior to the closing of the offering of the securitized utility tariff bonds described in this prospectus, to the effect that under existing case law, a reviewing court of competent jurisdiction would hold that the Securitization Act is constitutional in all material respects under the United States Constitution and, subject to all of the qualifications, limitations and assumptions set forth in its opinion, that the State pledge does not constitute an impermissible attempt to “contract away” the police power of the State of Kansas, and will not be disregarded under the reserved powers doctrine, and Husch Blackwell LLP expects to render an opinion, prior to the closing of the offering of the securitized utility tariff bonds described in this prospectus, to the effect that the Securitization Act has been duly enacted by the Kansas legislature and is in effect as of the closing of the offering, and that Husch Blackwell LLP is not aware of any constitutional infirmities with respect to the Securitization Act.

We and Atmos Energy have filed forms of each of the Sidley Austin LLP and Husch Blackwell LLP opinions as exhibits to an amendment to the registration statement of which this prospectus is a part, or to one of our periodic filings with the SEC.

The Kansas Commission May Adjust Securitized Utility Tariff Charges

The Securitization Act authorizes the Kansas commission to provide, and the Kansas commission has provided, in the financing order, that securitized utility tariff charges be adjusted at least semi-annually. These true-up adjustments are designed to:

| • |  | Correct any over-collections or under-collections during the preceding six months; and

| • |  | Ensure the expected recovery of amounts sufficient to timely provide all payments of debt service and other required amounts and charges in connection with the securitized utility tariff bonds.

Securitized Utility Tariff Charges are Nonbypassable

The Securitization Act provides that the securitized utility tariff charges are nonbypassable subject to the terms of the financing order. Under the financing order, “nonbypassable” means Atmos Energy is required to collect and must remit, consistent with the financing order, the nonbypassable securitized utility tariff charges that are applied to all existing and future retail customers within Atmos Energy’s service area in Kansas, as such service area exists on the date of the financing order, and as such service area may, at the discretion of Atmos

42

##### Table of Contents

Energy, be expanded or acquired as provided for in the financing order. If a customer disconnects from Atmos Energy’s gas distribution system and ceases to purchase natural gas by switching to an alternative source of energy that meets all of its energy needs, such customer would no longer be a retail customer and would not be subject to paying securitized utility tariff charges. While existing transportation customers at the time of the issuance of the securitized utility tariff bonds are not subject to the securitized utility tariff charges, retail customers who become transportation customers when securitized utility tariff charges are being recovered are required to pay a settlement fee prior to becoming a transportation customer. The settlement fee owed by the customer is to be based on the estimated present value of the expected charges the customer would have paid as a retail customer over the remaining period in which the securitized utility tariff charge is being recovered. The settlement fee will not be securitized utility tariff charges, but will be credited to Atmos Energy’s other retail customers once per year.

The Securitization Act Protects Securitized Utility Tariff Bondholders’ Security Interest on Securitized Utility Tariff Property

The Securitization Act provides that a valid and enforceable security interest in securitized utility tariff property will attach only after the issuance of a financing order, the execution and delivery of a security agreement in connection with the issuance of the securitized utility tariff bonds, the debtor having rights in the securitized utility tariff property or the power to transfer rights in the securitization utility tariff property and the receipt of value for the securitized utility tariff bonds. The security interest attaches automatically at the time when all of the foregoing conditions have been met without physical delivery of collateral or other act.

Upon perfection by filing a financing statement, under K.S.A. § 66-1,245(d), the security interest will be a perfected security interest in the securitized utility tariff property and will have priority in the order of perfection and take precedence over all claims of lien creditors and all competing security interests and other claims other than any security interest previously perfected. The servicer pledges in the servicing agreement to maintain the effectiveness of such financing statement.

The Securitization Act (K.S.A. §§ 66-1,245(e) and (f)) provides that priority of transfers of and security interests in securitized utility tariff property will not be affected by:

| • |  | The commingling of funds arising from securitized utility tariff charges with other funds; or

| • |  | Any later change in the securitized utility tariff charges pursuant to the true-up adjustment mechanism.

Furthermore, any other security interest that may apply to those funds will be terminated when they are transferred to a segregated account for an assignee or a financing party.

The Securitization Act Characterizes the Transfer of Securitized Utility Tariff Property as a True Sale

The Securitization Act (K.S.A. § 66-1,246(a)) provides that any sale, assignment or other transfer of securitized utility tariff property is a “true sale” of and an absolute transfer and not a pledge of or secured transaction relating to, the seller’s right, title, and interest in, to, and under the securitized utility tariff property if the documents governing the transaction expressly state that the transaction is a sale or other absolute transfer other than for federal and state income tax purposes. The Securitization Act (K.S.A. § 66-1,246(a)) provides that for all purposes other than federal and state income tax purposes, the parties’ characterization of a transaction as a sale of an interest in securitized utility tariff property is conclusive that the transaction is a true sale and that ownership has passed to the party characterized as the purchaser, regardless of whether the purchaser has possession of any documents evidencing or pertaining to such interest in securitized utility tariff property.

ATMOS ENERGY’S FINANCING ORDER

Background. In mid-February 2021, Kansas experienced sub-zero temperatures brought by Winter Storm Uri, which led to a significant increase in demand for electricity and natural gas. On February 14, 2021, a State of Disaster Emergency was issued by Kansas Governor Kelly due to expected prolonged low temperatures and the strain on natural gas and utility providers; at the time, wholesale natural gas prices were reflecting increases from 10 to 100 times their normal rates. On February 15, 2021, pursuant to K.S.A. § 77-536(a), the Kansas commission issued an Emergency Order in Docket No. 21-GIMX-303-MIS (Docket 21-303), directing jurisdictional natural gas utilities to take all reasonably feasible, lawful, and appropriate actions to ensure adequate transportation of natural gas to interconnected, non-jurisdictional Kansas utilities. Jurisdictional natural gas utilities were ordered to do everything necessary to ensure that natural gas service continued to be provided to their customers in Kansas. The Kansas commission authorized every jurisdictional natural gas distribution utility to defer extraordinary costs incurred during the winter event to a regulatory asset account.

In April 2021, the Kansas Legislature established the Utility Financing and Securitization Act (referred to in this prospectus as the Securitization Act), providing for a financing mechanism through which certain utilities can use securitization financing to recover “qualified extraordinary costs” (as defined in the Securitization Act) resulting from Winter Storm Uri, by issuing securitized utility tariff bonds. Securitized utility tariff bonds must be approved in a financing order issued by the Kansas commission. This provision of Kansas law, the Securitization Act—a Kansas senate substitute for House Bill 2072 (Volume 40 - Issue 16 - April 22, 2021)—is codified at K.S.A. §§ 66-1,240 - 66-1,253. A Kansas utility subject to the jurisdiction of the Kansas commission must apply to the Kansas commission in order for a financing order under the Securitization Act to authorize the issuance of securitized utility tariff bonds.

On May 25, 2022, Atmos Energy applied for a financing order under the Securitization Act. Under the Securitization Act and the financing order, Atmos Energy retail customers will pay securitized utility tariff charges, which are nonbypassable charges included in their monthly charges. Securitized utility tariff charges will fund payments of principal and interest on the securitized utility tariff bonds, together with related financing costs. Securitized utility tariff charges will be collected by Atmos Energy, as initial servicer, or its successor, as provided for in the financing order. Securitized utility tariff charges are required to be adjusted at least semi-annually, and more frequently as necessary, to ensure the projected recovery of amounts sufficient to provide timely payment of the scheduled principal, interest and other required amounts in connection with the securitized utility tariff bonds during the preceding six-month period.

On October 25, 2022, the Kansas commission issued its final order determining that Atmos Energy is entitled, pursuant to the Securitization Act, to finance, through the issuance of securitized utility tariff bonds in one or more tranches with an estimated aggregate principal amount equal to approximately $92.7 million (the qualified extraordinary costs less related financing costs and interest expense). The financing order also: (1) authorizes the issuance of securitized utility tariff bonds in an aggregate amount not to exceed the qualified extraordinary costs and financing costs (2) approves the creation of the securitized utility tariff property consisting of the right to impose and collect securitized utility tariff charges in an amount to be calculated as provided in the financing order; (3) approves the form of tariff, as provided in the financing order, to implement securitized utility tariff charges; (4) approves the securitization of the securitized utility tariff charges associated with the qualified extraordinary costs and financing costs, including the upfront financing costs and ongoing financing costs estimates (subject to review of the Kansas commission’s designated representative); and (5) approves the review of the structure of the proposed securitization financing through a pre-issuance review and an issuance advice letter process. The financing order became final and nonappealable on November 9, 2022.

Atmos Energy has filed the financing order with the SEC as an exhibit to the registration statement of which this prospectus forms a part.

Issuance of Securitized Utility Tariff Bonds. The financing order authorizes Atmos Energy to cause us to issue securitized utility tariff bonds in an estimated aggregate principal amount of $92,684,233, plus an

44

##### Table of Contents

additional amount that reflects the actual amount of qualified extraordinary costs incurred by Atmos Energy to be set forth in the issuance advice letter. Securitized utility tariff bonds are limited to a term of not longer than 32 years and are secured by or payable from securitized utility tariff property. The net proceeds from the sale of the securitized utility tariff bonds must be used to directly or indirectly to recover, finance or refinance qualified extraordinary costs.

Collection of Securitized Utility Tariff Charges. The financing order authorizes Atmos Energy to collect securitized utility tariff charges from its retail customers in an amount sufficient to provide for recovery of Atmos Energy’s qualified extraordinary costs and upfront and ongoing financing costs, which include principal and interest and certain ongoing fees and expenses associated with the securitized utility tariff bonds.

There is no “cap” on the level of securitized utility tariff charges that may be imposed on retail customers to pay on a timely basis scheduled principal and interest on the securitized utility tariff bonds. There is also no limit on how long securitized utility tariff charges may be imposed; pursuant to the financing order, the charges will be imposed until the securitized utility tariff bonds and all related financing costs have been paid in full.

Issuance Advice Letter. Following the determination of the final terms of the securitized utility tariff bonds and prior to their issuance, Atmos Energy is required to submit an issuance advice letter to the Kansas commission no later than the end of the first day after the pricing of the securitized utility tariff bonds. The issuance advice letter will:

| • |  | Demonstrate compliance with the provisions of the financing order;

| • |  | Indicate the final structure of the securitized utility tariff bonds;

| • |  | Provide the dollar amount of the initial securitized utility tariff charges and other information specific to the securitized utility tariff bonds;

| • |  | Provide the best available estimate of total ongoing financing costs;

| • |  | Report the initial securitized utility tariff charges and other information specific to the securitized utility tariff bonds to be issued, as the Kansas commission requires;

| • |  | Require Atmos Energy to update the benefit analysis to verify that the final structure of the securitization satisfies the statutory financial tests;

| • |  | Certify to the Kansas commission that the structure and pricing of the securitized utility tariff bonds results in the lowest securitized utility tariff charges consistent with market conditions at the time that the securitized utility tariff bonds are priced utilizing the lowest cost standard; and

| • |  | Specify the scheduled final payment dates of the securitized utility tariff bond tranches and the legal maturity for the securitized utility tariff bond tranches.

The initial securitized utility tariff charges and the final terms of the securitized utility tariff bonds set forth in the issuance advice letter shall become effective on the date of issuance of the securitized utility tariff bonds (which shall not occur prior to the fifth business day after pricing) unless prior to noon on the fourth business day after pricing the Kansas commission issues a disapproval letter finding that the proposed issuance advice letter does not comply with the Securitization Act and the financing order.

Form of Tariff: Winter Event Securitized Cost Rider (WESCR). Atmos Energy is required, prior to the issuance of any securitized utility tariff charges, to complete and file rate schedules in the form of tariff attached to the financing order. The WESCR establishes the initial securitized utility tariff charges. The WESCR also implements the procedures for periodic adjustments to the securitized utility tariff charges.

True-Ups. The financing order provides that securitized utility tariff charges will be reviewed and adjusted semi-annually to:

| • |  | Correct any over-collections or under-collections during the preceding six months; and

45

##### Table of Contents

| • |  | Ensure the expected recovery of amounts sufficient to timely provide all payments of debt service and other required amounts and charges in connection with the securitized utility tariff bonds.

Amounts remaining unpaid after final legal maturity of the securitized utility tariff bonds may be recovered but only to the extent that the securitized utility tariff charges are attributable to services rendered prior to the final legal maturity of the securitized utility tariff bonds.

In addition to semi-annual true-up adjustments, true-up adjustments may be made by the servicer more frequently at any time during the term of the securitized utility tariff bonds to correct any under-collection or over-collection to ensure timely payment of securitized utility tariff bonds as scheduled. In the event an interim true-up is necessary, the interim true-up adjustment should be filed by the 15th day of the current month for implementation in the first billing cycle of the following month. In no event would such interim true-up adjustments occur more frequently than every six months; provided, however, that there shall be quarterly true-up adjustments for the securitized utility tariff bonds remaining outstanding during the year immediately preceding the scheduled final payment date for the securitized utility tariff bonds.

Any delinquencies or under-collections in one retail customer class will be taken into account in the true-up mechanism to adjust the securitized utility tariff charges for all retail customers of Atmos Energy, not just the class of retail customers from which the delinquency or under-collection arose.

The financing order requires the servicer to make true-up adjustment filings with the Kansas commission. True-up adjustment filings must set forth the servicer’s calculation of the true-up adjustment to the securitized utility tariff charges. The Kansas commission has 30 days after the date of a true-up adjustment filing to confirm the mathematical accuracy of the servicer’s adjustment and to confirm that there are no clerical errors. Any true-up adjustment filed with the Kansas commission should be effective on its proposed effective date, which shall be not less than 30 days after filing. Any necessary corrections to the true-up adjustment, due to mathematical or clerical errors in the calculation of such adjustment or otherwise, must be made in future true-up adjustment filings.

The financing order provides that upon issuance of securitized utility tariff bonds or transfer of the securitized utility tariff property to the issuing entity, whichever occurs first, the financing order and the securitized utility tariff charges authorized by the financing order will become irrevocable and not subject to reduction, impairment, or adjustment by further act of the Kansas commission, except for any true-up adjustments made in accordance with the true-up adjustment mechanism in the financing order; provided, however, that such irrevocability shall not preclude the Kansas commission from extending the deadline for the issuance of securitized utility tariff bonds if requested to do so by Atmos Energy.

For more discussion of the true-up mechanism, see “THE SERVICING AGREEMENT—Securitized Utility Tariff Charge Adjustment Process” in this prospectus.

State and Commission Pledges. The State of Kansas and its agencies, including the Kansas commission, have pledged and agreed with bondholders that, pursuant to the Securitization Act, the state and its agencies will not: (a) alter the statute that authorizes the Kansas commission to create an irrevocable contract right or chose in action by the issuance of a financing order, to create securitized utility tariff property and to make the securitized utility tariff charges imposed by a financing order irrevocable, binding or nonbypassable charges for all existing and future retail customers within the service area of the public utility, (b) take or permit any action that impairs or would impair the value of securitized utility tariff property or the security for the securitized utility tariff bonds, or revises the Securitized Utility Tariff Costs (as defined in the Securitization Act) for which recovery is authorized, (c) impair the rights and remedies of the securitized utility tariff bondholders, assignees and other financing parties in any way, or (d) except for changes made pursuant to the true-up adjustment mechanism expressly allowed by law, reduce, alter, or impair the securitized utility tariff charges to be imposed, billed, charged, collected, and remitted for the benefit of the securitized utility tariff bondholders, any assignee, and any

46

##### Table of Contents

other financing parties, until any and all principal, interest, premium, financing costs and other fees, expenses or charges incurred and any contracts to be performed in connection with the related securitized utility tariff bonds have been paid and performed in full.

The Kansas commission has jurisdiction over Atmos Energy and its application for a financing order to recover qualified extraordinary costs and related financing costs pursuant to K.S.A. § 66-1,241(b).

The Securitization Act and financing order provides that securitized utility tariff property (whether associated with a single bond series covering the entire qualified extraordinary costs or with one of multiple bond series covering only a portion of the qualified extraordinary costs) constitutes a present property right for purposes of contracts concerning the sale or pledge of property and the property will continue to exist until securitized utility tariff bonds issued pursuant to the financing order have been paid in full and all financing costs and other costs of such securitized utility tariff bonds have been recovered in full. In addition, the interests of an assignee or pledgee in securitized utility tariff property (as well as the revenues and collections arising from the property) are not subject to setoff, counterclaim, surcharge, or defense by the utility or any other person or in connection with the bankruptcy of the utility or any other entity. The State of Kansas has pledged in the Securitization Act that it will not alter the provisions of the part of the Securitization Act which authorizes the Kansas commission to create an irrevocable contract right or chose in action by the issuance of a financing order, to create securitized utility tariff property, and to make the securitized utility tariff charges imposed by a financing order irrevocable, binding and nonbypassable charges, take or permit any action that impairs or would impair the value of the securitized utility tariff property, or, except for adjustments discussed in “—True-ups” and “The Servicing Agreement—Securitized Utility Tariff Charge Adjustment Process,” reduce, alter or impair the securitized utility tariff charges to be imposed, billed, charged, collected and remitted for the benefit of the securitized utility tariff bondholders, any assignee, and any other financing parties, until any and all principal, interest, premium, financing costs and other fees, expenses or charges incurred and any contracts to be performed in connection with the related securitized utility tariff bonds have been paid and performed in full. However, nothing will preclude limitation or alteration if full compensation is made by law for the full protection of the securitized utility tariff charges collected pursuant to the financing order and the full protection of the bondholders and any assignee or financing party. Please read “RISK FACTORS—Risks associated with potential judicial, legislative or regulatory actions.”

Adjustments to Allocation of Securitized Utility Tariff Charges. The financing order provides that Atmos Energy will allocate securitized utility tariff charges to its retail customer classes based on each retail customer classes’ percentage of the total estimated February 2021 sales volumes (“initial percentages”). The initial percentages will remain in effect throughout the life of the securitized utility tariff bonds; provided, however, if the customer count for a particular retail class declines by more than 10 percent from that identified in the 2021 Annual Report, then the allocation factors will be recalculated using the most recent 12-month weather normalized volume for each retail customer class. Furthermore, retail customer classes are cross-collateralized in the true-up adjustment mechanism, that is, projected revenue shortfalls in one retail customer class are remedied by adjustments to the securitized utility tariff charges for each retail customer class, not only the retail customer class with the projected revenue shortfalls. Please read “—Additional Other Similar Bonds.”

Any delinquencies or under-collections in one retail customer class will be taken into account in the true-up mechanism to adjust the securitized utility tariff charge for all retail customers of Atmos Energy, not just the class of retail customers from which the delinquency or under-collection arose.

Servicing Agreement. In the financing order, the Kansas commission authorized Atmos Energy, as the initial servicer, to enter into the servicing agreement which is described under “THE SERVICING AGREEMENT” in this prospectus.

Additional Other Similar Bonds. Atmos Energy, upon receipt of an additional financing order, may finance qualified extraordinary costs through the issuance of additional securitized utility tariff bonds in Kansas issued

by another subsidiary or affiliated entity of Atmos Energy pursuant to a separate financing order and secured by separate securitized utility tariff property.

Binding on Successors. The financing order, along with the securitized utility tariff charges authorized in the financing order, is binding on:

| • |  | Atmos Energy;

| • |  | Any successor to Atmos Energy;

| • |  | Any other entity responsible for billing and collecting securitized utility tariff charges on behalf of us; and

| • |  | Any successor to the Kansas commission.

THE DEPOSITOR, SELLER, INITIAL SERVICER AND SPONSOR

About Atmos Energy

Background Information. Atmos Energy, headquartered in Dallas, Texas, and incorporated in Texas and Virginia, is the country’s largest natural-gas-only distributor based on number of customers. Atmos Energy serves approximately 3.3 million residential, commercial, public authority and industrial customers located primarily in the South. At September 30, 2022, Atmos Energy had 4,791 employees, including 173 employees in Kansas. Atmos Energy, as a regulated utility, is subject to the regulations and oversight of various state and local regulatory authorities as well as the United States Department of Transportation. Additionally, Atmos Energy’s operations are also subject to state and federal laws regulation environmental matters. Generally, Atmos Energy, acting as the initial servicer, and any successor servicer, referred to in this prospectus as the “servicer,” will service the securitized utility tariff property securing the securitized utility tariff bonds under a servicing agreement with us. Neither Atmos Energy nor any other affiliate (other than us) is an obligor on the securitized utility tariff bonds.

Service Area. As of September 30, 2022, Atmos Energy owned approximately 4,100 miles of pipeline and served 107 communities in Kansas. Atmos Energy’s service area in Kansas includes all territory within the State of Kansas subject to the jurisdiction of the Kansas commission in which Atmos Energy provides natural gas distribution service as of October 25, 2022 (the date of the financing order). As of September 30, 2022, Atmos Energy supplied natural gas service to approximately 139,000 customers in Kansas, of which approximately 99.65% will be subject to the securitized utility tariff charges. During its fiscal year 2022, Atmos Energy had $43 million in capital expenditures and spent $467,000 towards charitable giving in Kansas.

Municipalization. Kansas securitization legislation allows a natural gas public utility, in its sole discretion, to apply to the Kansas commission for a financing order to recover qualified extraordinary costs through the issuance of bonds. The Securitization Act specifies that securitized utility tariff charges approved by a financing order shall be collected by a utility as well as its “successors or assignees.” In the servicing agreement, Atmos Energy has covenanted to assert in an appropriate forum that any municipality that acquires any portion of Atmos Energy’s natural gas distribution facilities by expropriation, including upon the expiration of any franchise agreement, must be treated as a successor to Atmos Energy under the Securitization Act and the financing order. However, the involved municipality might assert that it should not be treated as a successor to Atmos Energy for these purposes and that its distribution customers are not responsible for payment of securitized utility tariff charges. Please read “RISK FACTORS—Risks associated with potential judicial, legislative or regulatory actions—A municipal entity may seek to acquire portions of Atmos Energy’s gas distribution facilities and avoid payment of the securitized utility tariff charges” in this prospectus.

Credit Policy

Atmos Energy is required to service all applicants in its service area, subject to certain exceptions enumerated by the Kansas commission. To minimize credit risk, Atmos Energy assesses the credit worthiness of new customers, requires deposits when necessary, assesses late fees, pursues collection activities and disconnects service for nonpayment. After disconnection, accounts are written off when deemed uncollectible. At each reporting period, Atmos Energy assesses the allowance for uncollectible accounts based on historical experience, current conditions and consideration of expected future conditions. Circumstances that could affect allowance estimates include but are not limited to customer issues, natural gas prices, customer deposits, and general economic conditions. In connection with the COVID-19 pandemic, Atmos Energy suspended its activity of disconnecting due to non-payment beginning in 2020. Atmos Energy resumed disconnecting due to non-payment in July 2021.

Billing Process and Payment Options

Atmos Energy reads meters and bills customers on a monthly cycle basis. Atmos Energy estimates volumes from the last meter read to the balance sheet date and accrues revenue for gas delivered but not yet billed. Atmos Energy customers have a variety of payment options, including autopay, website/phone, mailing in checks, and payment stations. The graph below is illustrative of the utilization of various payment options by Atmos Energy’s customers for fiscal year 2022.

Collection, Termination of Service and Write-off Policy

Accounts receivable arise from natural gas sales to residential, commercial, industrial, public authority, and other customers. Accounts receivable balances include unbilled amounts which represent a customer’s consumption of gas from the date of the last cycle through the last day of the month. The receivable balances are short term and generally do not extend beyond one month.

In response to the COVID-19 pandemic, regulators issued collection moratoriums, which required Atmos Energy to temporarily suspend customer collection activities and to stop charging late fees. After regulators lifted these moratoriums, Atmos Energy resumed customer collection activities during the third quarter of fiscal 2021. These regulatory orders influenced Atmos Energy’s bad debt expense and writeoffs from fiscal 2020 through 2022.

Atmos Energy is actively working with customers experiencing financial hardship to offer flexible payment options and to direct them to aid agencies for financial assistance. The allowance for uncollectible accounts reflects the expected impact on the customers’ ability to pay. The allowance for uncollectible accounts also reflects the fact that Atmos Energy has the ability to recover the gas cost portion of uncollectible accounts through Atmos Energy’s gas cost recovery mechanisms in five states, which covers approximately 81% of Atmos Energy’s residential and commercial customers.

Write-off and Delinquency Experience

The following tables set forth information relating to the total billed revenues and write-off experience for the past five years. Such historical information is presented because Atmos Energy’s actual experience with respect to write-offs and delinquencies may be indicative of its future experience, which will affect the timing of securitized utility tariff charge collections. Atmos Energy does not expect, but there can be no certainty, that the delinquency or write-off experience with respect to securitized utility tariff charge collections will differ substantially from the rates indicated. Write-off and delinquency data is affected by factors such as the overall economy, weather and changes in collection practices. The net write-off and delinquency experience is expected, but there can be no certainty, to be similar to Atmos Energy’s previous experience.

Competition and Alternatives to Gas as An Energy Source for Atmos Energy Customers

Atmos Energy competes with other natural gas suppliers and suppliers of alternative fuels for sales to industrial customers. Atmos Energy competes in every aspect of the business with alternative energy sources including electricity. Electric utilities offer electricity as a rival energy source for the space heating, water heating and cooking markets. Promotional incentives, improved equipment efficiencies and promotional rates all contribute to the acceptability of electrical equipment. The principal means to compete against alternative fuels is lower prices, and natural gas historically has maintained its price advantage in the residential, commercial and industrial markets. Atmos Energy’s pipeline and storage operations have historically faced competition from other existing intrastate pipelines seeking to provide transportation and other services for customers. Over the last few years, new pipelines have been completed which has increased the level of competition in this segment of Atmos Energy’s business.

Additional Natural Gas Utility Considerations

An objective of Atmos Energy’s supply-sourcing strategy is to provide value to its customers through reliable, competitively priced and flexible natural gas supply and transportation from multiple production areas and suppliers. This strategy is designed to mitigate the impact on Atmos Energy’s supply from physical interruption, financial difficulties of a single supplier, natural disasters and other unforeseen force majeure events, as well as to ensure that adequate supply is available to meet the variations of customer demand.

Atmos Energy maintains 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. Atmos Energy does not anticipate problems with securing natural gas supply to satisfy customer demand.

Weather Rules

Kansas statutory requirements and the rules and regulations of the Kansas commission, which may change from time to time, regulate and control the right to disconnect service. The Kansas commission enforces specific weather rules on Atmos Energy in extreme weather conditions. A natural gas utility must not disconnect service for a residential customer on a day when the temperature is predicted to fall below 35 degrees Fahrenheit within the following 48 hours, according to the applicable local National Weather Service forecast. To the extent these customers do not pay for their natural gas service, Atmos Energy will not be able to collect securitized utility tariff charges from these customers. Weather moratoriums prohibit Atmos Energy from disconnecting a customer for a short period of time during a weather event, typically a few days.

Forecasting Natural Gas Customers

For all classes, including residential and small commercial, Atmos Energy forecasts natural gas customer counts based on trends and reasonable expectations of future growth. Past data for residential and commercial customers shows trends to be at a consistent rate of increase for Atmos Energy’s service area. Historically, the number of Atmos Energy’s larger industrial customers has not changed significantly and Atmos Energy does not usually forecast any industrial customer growth unless there is a known customer coming into its service area.

Once per year (typically in the fourth quarter), Atmos Energy completes a five-year forecast of customers where the models are completely re-estimated and where large individual customers are evaluated. The output of this exercise is the customer count and sales forecast that underlies Atmos Energy’s annual five-year business plan. This forecast is typically the first step in a multi-stage planning process that determines customer growth, average volume usage, and revenue.

Annual Forecast Variance

The following table sets forth information related to annual forecast variance for retail customer counts in Atmos Energy’s service area in Kansas by customer type (residential or non-residential) for the past five fiscal years. Variances between actual customer counts and forecasted customer counts can be caused by a number of factors such as: the timing of completion of new housing development (i.e., when meter connected), delinquent customers not disconnected due to COVID-19 moratoriums during 2020 and 2021, the timing of completion of Atmos Energy capital projects, abnormal weather conditions (i.e., colder or warmer than normal) impacting the timing of when a customer reconnects or disconnects service, and the health of the overall economy.

ATMOS ENERGY KANSAS SECURITIZATION I, LLC, THE ISSUING ENTITY

General

We are a special purpose limited liability company formed under the Delaware Limited Liability Company Act pursuant to a limited liability company agreement executed by our sole member, Atmos Energy, and the filing of a certificate of formation with the Secretary of State of Delaware. We were formed on October 28, 2022.

We have been organized as a wholly owned special purpose limited liability company subsidiary of Atmos Energy for the limited purposes described under “—Restricted Purposes” below. At the time of the issuance of the securitized utility tariff bonds, our assets will consist primarily of the securitized utility tariff property and the other collateral held under the Indenture and the series supplement for the securitized utility tariff bonds.

Our limited liability agreement will be amended and restated prior to the issuance date and references in this prospectus to the LLC Agreement mean our amended and restated limited liability company agreement. The LLC Agreement restricts us as the issuing entity from engaging in activities other than those activities related to the purposes described in this section or those authorized by the terms of the basic documents or the other agreements referenced under “—Restricted Purposes” below. Other than purchasing the securitized utility tariff property and issuing the securitized utility tariff bonds, we have no business operations, but we will pay our sole member Atmos Energy an administration fee for its out-of-pocket expenses incurred by it in connection with its services to us in accordance with the LLC Agreement. Selected provisions of the LLC Agreement, a copy of which has been filed as an exhibit to the registration statement of which this prospectus is a part, are summarized below. On the date of issuance of the securitized utility tariff bonds, our capital will be equal to % of the initial principal amount of the securitized utility tariff bonds issued on the issuance date or such other amount as may allow the securitized utility tariff bonds to achieve the desired security rating and treat the securitized utility tariff bonds as debt under applicable guidance issued by the Internal Revenue Service, which we also refer to as the IRS.

As of the date of this prospectus, we have not carried on any business activities and have no operating history. Our fiscal year end is September 30.

Our assets will consist of:

| • |  | the securitized utility tariff property;

| • |  | our rights under the sale agreement, under the administration agreement and under the bill of sale delivered by Atmos Energy under the sale agreement;

| • |  | our rights under the servicing agreement and any subservicing, agency, administration, intercreditor or collection agreements executed in connection with the servicing agreement;

| • |  | the collection account and all subaccounts of the collection account;

| • |  | all present and future claims, demands, causes and choses in action in respect of any or all of the foregoing; and

| • |  | all payments on or under and all proceeds in respect of any of the foregoing.

The Indenture provides that the securitized utility tariff property, as well as our other assets, will be pledged by us to the trustee to secure our obligations in respect of the securitized utility tariff bonds. Pursuant to the Indenture, the collected securitized utility tariff charges remitted to the trustee by the servicer must be used to pay principal of and interest on the securitized utility tariff bonds and our other obligations specified in the Indenture.

The LLC Agreement and the Indenture do not permit us to engage in any activities not directly related to these purposes, including issuing securities (other than the securitized utility tariff bonds), acquiring obligations or making loans to other persons. The list of permitted activities set forth in the LLC Agreement may not be altered, amended or repealed without the affirmative vote of a majority of our managers, which vote must include the affirmative vote of our independent manager. The LLC Agreement and the Indenture will prohibit us from issuing any securitized utility tariff bonds (as such term is defined in the Securitization Act) other than the securitized utility tariff bonds being offered pursuant to this prospectus.

Our Relationship with Atmos Energy

On the issuance date for the securitized utility tariff bonds, Atmos Energy will sell the securitized utility tariff property to us pursuant to the sale agreement between us and Atmos Energy. Atmos Energy will service such securitized utility tariff property pursuant to the servicing agreement between us and Atmos Energy related to the securitized utility tariff bonds. Atmos Energy will provide certain administrative services to us pursuant to the administration agreement between us and Atmos Energy.

Managers and Officers

Pursuant to the LLC Agreement, our business will be managed initially by three or more managers (with such number being increased or decreased from time to time in the sole and absolute discretion of Atmos Energy as permitted by the LLC Agreement), with one of the managers being an independent manager, in each case appointed from time to time by Atmos Energy or, in the event Atmos Energy transfers its interest in us, by the owner or owners of us. Following the issuance of the securitized utility tariff bonds, we will have at least one independent manager, who, among other things, is an individual who (1) has prior experience as an independent director, independent manager or independent member for special-purpose entities, (2) is employed by a nationally recognized company that provides professional independent managers and other corporate services in the ordinary course of its business, (3) is duly appointed as an independent manager and (4) is not and has not been for at least five years from the date of his or her or their appointment, and while serving as an independent manager will not be, any of the following:

| special purpose bankruptcy remote entity); provided, that the indirect or beneficial ownership of stock of Atmos Energy or its affiliates through a mutual fund or similar diversified investment vehicle with respect to which the owner does not have discretion or control over the investments held by such diversified investment vehicle shall not preclude such owner from being an independent manager;

| • |  | a creditor, supplier or service provider (including provider of professional services) to us, Atmos Energy or any of their respective equity holders or affiliates (other than a nationally-recognized company that routinely provides professional independent managers and other corporate services to us, Atmos Energy or any of their affiliates in the ordinary course of its business);

| • |  | a family member of any of the foregoing; or

| • |  | a person who controls (whether directly, indirectly or otherwise) any of the foregoing.

Manager Fees and Limitation on Liabilities

We will not compensate our managers, other than the independent manager, for their services on behalf of us. To the extent permitted by law, we will reimburse the managers for reasonable out-of-pocket expenses incurred by them in connection with their service to us. This reimbursement will be determined by our managers without regard to our income, and we will consider this reimbursement an operating expense. We will pay the annual fee of the independent manager in accordance with the LLC Agreement, which fee will initially be $3,000 per year. Such fee of the independent manager will be determined without regard to our income, and will be considered one of our operating expenses subject to limitations in the financing order. These expenses include the reasonable compensation, expenses and disbursements of the agents, representatives, experts and counsel that the independent manager may employ in connection with the exercise and performance of his or her rights and duties under the LLC Agreement.

The LLC Agreement provides that to the extent permitted by law, the managers will not be personally liable for any of our debts, obligations or liabilities. The LLC Agreement further provides that, except as described below, to the fullest extent permitted by law, we will indemnify the managers against any liability incurred in connection with their services as managers for us if they acted in good faith and in a manner which they reasonably believed to be in or not opposed to our best interests. With respect to a criminal action, the managers will be indemnified unless they had reasonable cause to believe their conduct was unlawful. We will not indemnify any manager for any judgment, penalty, fine or other expense directly caused by such manager’s fraud, gross negligence or willful misconduct. In addition, unless ordered by a court, we will not indemnify the managers if a final adjudication establishes that their acts or omissions involved intentional misconduct, fraud or a knowing violation of the law and were material to the cause of action. We will not indemnify managers in an action brought by us. We will pay any indemnification amounts owed to the managers out of funds in the accounts held under the Indenture for the securitized utility tariff bonds, subject to the priority of payments described under “DESCRIPTION OF THE SECURITIZED UTILITY TARIFF BONDS—How Funds in the Collection Account Will Be Allocated” in this prospectus.

We are a Separate and Distinct Legal Entity from Atmos Energy

The LLC Agreement provides that we may not file a voluntary petition for relief under the Bankruptcy Code, without the affirmative vote of Atmos Energy, our sole member, and the affirmative vote of all of our

58

##### Table of Contents

managers, including the independent manager. Atmos Energy has agreed that it will not cause us to file a voluntary petition for relief under the Bankruptcy Code. This does not guarantee, however, that we will not become a debtor under the Bankruptcy Code. The LLC Agreement requires us, except for financial reporting purposes (to the extent required by generally accepted accounting principles) and for federal income tax purposes, and, to the extent consistent with applicable state tax law, state income and franchise tax purposes, to maintain our existence separate from Atmos Energy including:

| • |  | taking all necessary steps to continue our identity as a separate legal entity;

| • |  | making it apparent to third persons that we are an entity with assets and liabilities distinct from those of Atmos Energy, affiliates of Atmos Energy or any other Person; and

| • |  | making it apparent to third persons that, except for federal and certain other tax purposes, we are not a division of Atmos Energy or any of its affiliated entities or any other Person.

Our principal place of business is 1800 Three Lincoln Centre, 5430 LBJ Freeway, Dallas, Texas 75240 and our telephone number at such address is (972) 934-9227.

Administration Agreement

Atmos Energy will, pursuant to an administration agreement between Atmos Energy and us, provide administrative services to us, including services relating to the preparation of financial statements, required filings with the SEC, any tax returns we might be required to file under applicable law, qualifications to do business, and minutes of our managers’ meetings. We will pay Atmos Energy a fixed fee of $100,000 per annum, payable in installments of $50,000 on each payment date for performing these services (which will be pro-rated for the first payment date), plus we will reimburse Atmos Energy for all costs and expenses for services performed by unaffiliated third parties and actually incurred by Atmos Energy in performing such services.

THE SECURITIZED UTILITY TARIFF CHARGES

Atmos Energy will be the initial servicer of the securitized utility tariff property. Billing will begin with the first billing cycle of the month following the issuance of the securitized utility tariff bonds. Securitized utility tariff charges will be calculated on a fixed monthly charge per retail customer, pursuant to the method described in the Winter Event Securitized Cost Recovery Rider. The fixed monthly per retail customer securitized utility tariff charge will be adjusted semi-annually pursuant to the true-up adjustment mechanism. In addition to semi-annual true-up adjustments, true-up adjustments may be made by the servicer more frequently at any time during the term of the securitized utility tariff bonds to correct any under-collection to ensure timely payment of securitized utility tariff bonds as scheduled. In the event an interim true-up is necessary, the interim true-up adjustment should be filed by the 15th day of the current month for implementation in the first billing cycle of the following month. The securitized utility tariff charge per retail customer initially will be calculated using the retail customer count reported in the most recent Atmos Energy Annual Report and will be updated semi-annually. If the customer count for a particular retail class declines by more than 10 percent from that identified in the 2021 Annual Report, then the allocation factors will be recalculated using the most recent 12-month weather normalized volume for each retail customer class. The securitized utility tariff charges shall be collected over the expected life of the securitized utility tariff bonds. However, securitized utility tariff charges shall be collected until all of the securitized utility tariff bonds and related ongoing financing costs are paid in full.

The initial securitized utility tariff charges listed in the table below will be imposed on Atmos Energy’s retail customers in each securitized utility tariff charge customer class at the applicable rate for the class determined pursuant to the financing order. These securitized utility tariff charges may be adjusted semi-annually, or more frequently under certain circumstances, by the servicer in accordance with its filings with the Kansas commission. Please read “ATMOS ENERGY’S FINANCING ORDER” in this prospectus.

Initial Securitized Utility Tariff Charges

Each retail customer will be designated as a customer belonging to a securitized utility tariff charge retail customer class.

DESCRIPTION OF THE SECURITIZED UTILITY TARIFF BONDS

General

We have summarized selected provisions of the Indenture and the securitized utility tariff bonds below. This summary is subject to the terms and provisions of the Indenture and the series supplement for the securitized utility tariff bonds, forms of which we have filed with the SEC as an exhibit to the registration statement of which this prospectus forms a part. You should carefully read the summary below and the terms and provisions of the Indenture that may be important to you before investing in the securitized utility tariff bonds. Please read “WHERE YOU CAN FIND MORE INFORMATION” in this prospectus.

The securitized utility tariff bonds are not a debt, liability or other obligation of the State of Kansas, the Kansas commission or of any other political subdivision, governmental agency, authority or instrumentality of the State of Kansas and do not represent an interest in or legal obligation of Atmos Energy or any of its affiliates other than us. Neither Atmos Energy nor any of their affiliates will guarantee or insure the securitized utility tariff bonds. The financing order authorizing the issuance of the securitized utility tariff bonds does not constitute a pledge of the full faith and credit of the State of Kansas, the Kansas commission or of any other political subdivision of the State. The issuance of the securitized utility tariff bonds under the Securitization Act will not directly, indirectly or contingently obligate the State of Kansas, the Kansas commission or any other political subdivision of the State to levy or to pledge any form of taxation for the securitized utility tariff bonds or to make any appropriation for their payment.

We will issue the securitized utility tariff bonds and secure their payment under an Indenture that we will enter into with the trustee. We will issue the securitized utility tariff bonds in minimum denominations of $2,000 and in integral multiples of $1,000 in excess thereof, except that we may issue one bond in a smaller denomination. The initial principal amount, scheduled final payment date, final maturity date and interest rate for the securitized utility tariff bonds are stated in the table below. In no event shall the scheduled final payment date for the securitized utility tariff bonds exceed 10 years from the date of issuance of the securitized utility tariff bonds. The legal final maturity of the securitized utility tariff bonds shall not exceed 12 years from the date of issuance of the securitized utility tariff bonds.

Tranche |  | Expected Weighted Average Life (Years) |  |  | Principal Amount Offered |  |  | Scheduled Final Payment Date |  |  | Final Maturity Date |  |  | Interest Rate |
A |  |  |  |  |  | $ | 95,000,000 |  |  |  |  |  |  |  |  |  |  |  |  | %

The scheduled final payment date for the securitized utility tariff bonds is the date when the outstanding principal balance will be reduced to zero if we make payments according to the expected amortization schedule. The final maturity date for the securitized utility tariff bonds is the date when we are required to pay the entire remaining unpaid principal balance, if any, of all outstanding securitized utility tariff bonds. The failure to pay principal by the final maturity date is an event of default for the securitized utility tariff bonds, but the failure to pay principal by the scheduled final payment date will not be an event of default. Please read “—Payments of Interest and Principal on the Securitized Utility Tariff Bonds” and “—What Constitutes an Event of Default on the Securitized Utility Tariff Bonds” in this prospectus.

Payments of Interest and Principal on the Securitized Utility Tariff Bonds

Interest will accrue on the principal balance of the securitized utility tariff bonds at the interest rate of %. Beginning , 2024, we will make payments on the securitized utility tariff bonds semi-annually on and of each year, or, if that day is not a business day, the following business day (each, a “payment date”). Interest payments on the securitized utility tariff bonds will be made from collections of the securitized utility tariff charges, including amounts available in the excess funds subaccount and, if necessary, the amounts available in the capital subaccount.

61

##### Table of Contents

On each payment date, we will pay interest on the securitized utility tariff bonds equal to the following amounts:

| • |  | any interest payable but unpaid on any prior payment date, together with interest on such unpaid interest, if any; and

| • |  | accrued interest on the principal balance of the securitized utility tariff bonds from the close of business on the preceding payment date, or the date of the original issuance of the securitized utility tariff bonds, after giving effect to all payments of principal made on the preceding payment date, if any.

We will pay interest on the securitized utility tariff bonds before we pay principal on the securitized utility tariff bonds. We will calculate the interest on the securitized utility tariff bonds on the basis of a 360-day year consisting of 12, 30-day months.

The failure to pay accrued interest on the securitized utility tariff bonds on any payment date (even if the failure is caused by a shortfall in securitized utility tariff charges received) will result in an event of default of securitized utility tariff bonds unless such failure is cured within five business days. If interest is not paid within that five-business day period, we will pay such defaulted interest (plus interest on such defaulted interest at the applicable interest rate to the extent lawful) to the persons who are holders of securitized utility tariff bonds on a special record date (as defined in the Indenture). The special record date will be at least 15 business days prior to the date on which the trustee is to make a special payment (a special payment date). We will fix any special record date and special payment date and, at least 10 days before such special record date, we will mail to each affected securitized utility tariff bondholder a notice that states the special record date, the special payment date and the amount of defaulted interest (plus interest on such defaulted interest) to be paid. An event of default will automatically trigger an event of default under the securitized utility tariff bonds. See “—What Constitutes an Event of Default on the Securitized Utility Tariff Bonds” below.

On any payment date with respect to the securitized utility tariff bonds, we generally will pay principal of securitized utility tariff bonds only until the outstanding principal balance has been reduced to the principal balance specified for that payment date in the expected amortization schedule, but only to the extent funds are available. Accordingly, principal may be paid later, but generally not sooner, than reflected in the expected amortization schedule, except in the case of an acceleration. Please read “RISK FACTORS—Other risks associated with an investment in the securitized utility tariff bonds” and “WEIGHTED AVERAGE LIFE AND YIELD CONSIDERATIONS FOR THE SECURITIZED UTILITY TARIFF BONDS” in this prospectus.

The trustee will retain in the excess funds subaccount for payment on later payment dates any collections of securitized utility tariff charges in excess of amounts payable as:

| • |  | fees and expenses of the servicer (including the servicing fee), the independent manager and the trustee,

| • |  | payments of interest and principal on the securitized utility tariff bonds;

| • |  | allocations to the capital subaccount; and

| • |  | investment earnings on amounts in the capital subaccount released to us.

If the trustee receives insufficient collections of securitized utility tariff charges for the securitized utility tariff bonds for any payment date, and amounts in the collection account (and the applicable subaccounts of that collection account) are not sufficient to make up the shortfall, principal may be paid later than expected, as described in this prospectus. The failure to make a scheduled payment of principal on the securitized utility tariff bonds because there are not sufficient funds in the collection account does not constitute a default or an event of default under the Indenture, except for the failure to make the scheduled payment of principal due upon the final maturity of the securitized utility tariff bonds.

The trustee will pay on each payment date to the holders of securitized utility tariff bonds, to the extent of available funds in the collection account, all payments of principal and interest then due on such securitized

62

##### Table of Contents

utility tariff bonds (other than special payments as defined in the Indenture). The trustee will make each such payment to the securitized utility tariff bondholders, other than the final payment, on the applicable payment date. If the securitized utility tariff bonds are ever issued in definitive certificated form, however, the final payment with respect to the securitized utility tariff bonds will be made only upon presentation and surrender of such securitized utility tariff bond at the office or agency of the trustee specified in the notice given by the trustee with respect to such final payment. The trustee will mail notice of the final payment to the securitized utility tariff bondholders no later than five days prior to the final payment date, specifying that such final payment will be payable only upon presentation and surrender of such securitized utility tariff bond and the place where such securitized utility tariff bond may be presented and surrendered for payment.

The securitized utility tariff bonds will originally be issued in book-entry form, and we do not expect that the securitized utility tariff bonds will be issued in definitive certificated form. At the time, if any, we issue the securitized utility tariff bonds in the form of definitive certificated securitized utility tariff bonds and not to The Depository Trust Company (“DTC”) or its nominee, the trustee will make payments as described below under “—Definitive Certificated Securitized Utility Tariff Bonds.”

On each payment date, the amount to be paid as principal on the securitized utility tariff bonds will equal without duplication:

| • |  | the unpaid principal amount due on the final maturity date, plus;

| • |  | the unpaid principal amount due upon acceleration following an event of default, plus;

| • |  | the unpaid and previously scheduled payments of principal, plus;

| • |  | the principal scheduled to be paid on that payment date

but only to the extent funds are available in the collection account (including all applicable subaccounts) after payment of certain of our fees and expenses and after payment of interest as described in the section above.

However, we will not pay principal of the securitized utility tariff bonds on any payment date if making the payment would reduce the principal balance to an amount lower than the amount specified in the expected amortization schedule below on that payment date. Any excess funds remaining in the collection account after payment of principal, interest, applicable fees and expenses and payments to the applicable subaccounts of the collection account will be retained in the excess funds subaccount until applied on a subsequent payment date.

The entire unpaid principal amount of the securitized utility tariff bonds will be due and payable:

| • |  | on the final maturity date; and

| • |  | if an event of default under the Indenture occurs and is continuing and the trustee or the holders of a majority in principal amount of the securitized utility tariff bonds have declared the securitized utility tariff bonds to be immediately due and payable.

If there is a shortfall in the amounts available to make principal payments on the securitized utility tariff bonds that are due and payable on the final maturity date or upon an acceleration following an event of default under the Indenture, the trustee will distribute principal from the collection account based on the principal amount then due and payable on the payment date and if there is a shortfall in the remaining amounts available to make principal payments on the securitized utility tariff bonds that are scheduled to be paid, the trustee will distribute principal from the collection account based on the principal amount then scheduled to be paid on the payment date.

However, the nature of our business will result in payment of principal upon an acceleration of the securitized utility tariff bonds being made only as funds become available. Please read “RISK FACTORS—Risks associated with the unusual nature of the securitized utility tariff property” and “—You may experience material payment delays or incur a loss on your investment in the securitized utility tariff bonds because the source of funds for payment is limited.”

63

##### Table of Contents

If any special payment date or other date specified herein for distribution of any payments to holders of securitized utility tariff bonds is not a business day, payments scheduled to be made on such special payment date or other date may be made on the next succeeding business day, and no interest will accrue upon such payment during the intervening period. “Business day” means any day other than a Saturday, a Sunday or a day on which banking institutions in New York, New York, Chicago, Illinois or Dallas, Texas, are, or DTC is, required or authorized by law or executive order to remain closed.

Neither we nor Atmos Energy makes any representation or warranty that any amounts actually collected arising from securitized utility tariff charges will in fact be sufficient to meet payment obligations on the securitized utility tariff bonds or that assumptions made in calculating securitized utility tariff charges will in fact be realized.

The expected amortization schedule below sets forth the principal balance that is scheduled to remain outstanding on each payment date for the securitized utility tariff bonds from the issuance date to the scheduled final payment date. Similarly, the expected sinking fund schedule below sets forth the corresponding principal payment that is scheduled to be made on each payment date for the securitized utility tariff bonds from the issuance date to the scheduled final payment date. In establishing these schedules, we have made the assumptions specified in the bullet points under the weighted average life sensitivity table below under “WEIGHTED AVERAGE LIFE AND YIELD CONSIDERATIONS FOR THE SECURITIZED UTILITY TARIFF BONDS,” among other assumptions.

Expected Amortization Schedule
Outstanding Principal Balance |  |  |  |

Payment Date |  | Tranche A Amount |
Initial Principal Amount |  |  |  |

On each payment date, the trustee will make principal payments to the extent the principal balance of the securitized utility tariff bonds exceeds the amount indicated for that payment date in the table above and to the extent of funds available in the collection account after payment of certain of our fees and expenses and after payment of interest. If sufficient funds are available on each payment date, principal payments will be in the amounts indicated for each payment date in the expected sinking fund schedule below.

We cannot assure you that principal payments will be made or that the principal balance of the securitized utility tariff bonds will be reduced at the rates indicated in the schedules above. Principal payments and the actual reduction in principal balances may occur more slowly. Principal payments and the actual reduction of principal balances will not occur more quickly than indicated in the above schedules, except that the total outstanding principal balance of and interest accrued on the securitized utility tariff bonds may be accelerated upon an event of default under the Indenture. The securitized utility tariff bonds will not be in default if principal is not paid as specified in the schedules above unless the principal is not paid in full on or before the final maturity date.

Redemption of the Securitized Utility Tariff Bonds

There are no redemption rights associated with the securitized utility tariff bonds.

Securitized Utility Tariff Bonds Will Be Issued in Book-Entry Form

The securitized utility tariff bonds will be available to investors only in the form of book-entry securitized utility tariff bonds. You may hold your bonds through DTC in the United States, Clearstream Banking, Luxembourg, S.A., referred to as Clearstream, or Euroclear in Europe. You may hold the securitized utility tariff bonds directly with one of these systems if you are a participant in the system or indirectly through organizations that are participants.

The Role of DTC, Clearstream and Euroclear.

Cede & Co., as nominee for DTC, will hold the global bond or bonds representing the securitized utility tariff bonds. Clearstream and Euroclear will hold omnibus positions on behalf of the Clearstream customers and Euroclear participants, respectively, through customers’ securities accounts in Clearstream’s and Euroclear’s names on the books of their respective depositaries. These depositaries will, in turn, hold these positions in customers’ securities accounts in the depositaries’ names on the books of DTC.

The Function of DTC. DTC, the world’s largest securities depository, is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code, and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds and provides asset servicing for over 3.5 million issues of U.S. and non-U.S. equity issues, corporate and municipal debt issues, and money market instruments (from over 100 countries) that DTC’s participants (“Direct Participants”) deposit with DTC. DTC also facilitates the post-trade settlement among Direct Participants of sales and other securities transactions in deposited securities, through electronic computerized book-entry transfers and pledges between Direct Participants’ accounts, thereby eliminating the need for physical movement of securities certificates. Direct Participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations. DTC is a wholly owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, and clearing corporations that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly (“Indirect Participants”). The DTC Rules applicable to its participants are on file with the SEC. More information about DTC can be found at www.dtcc.com and www.dtc.org. The contents of such websites do not constitute a part of the registration statement of which this prospectus forms a part.

The Function of Clearstream. Clearstream is incorporated under the laws of Luxembourg. Clearstream holds securities for its customers and facilitates the clearance and settlement of securities transactions between Clearstream customers through electronic book-entry changes in accounts of Clearstream customers, thereby eliminating the need for physical movement of securities. Transactions may be settled by Clearstream in any of various currencies, including United States dollars. Clearstream provides to its customers, among other things, services for safekeeping, administration, clearance and settlement of internationally traded securities and

65

##### Table of Contents

securities lending and borrowing. Clearstream also deals with domestic securities markets in various countries through established depositary and custodial relationships. Clearstream is registered as a bank in Luxembourg and therefore is subject to regulation by the Luxembourg Commission de Surveillance du Secteur Financier, which supervises Luxembourg banks. Clearstream’s customers are world-wide financial institutions including underwriters, securities brokers and dealers, banks, trust companies and clearing corporations, among others, and may include the underwriter of the securitized utility tariff bonds. Clearstream’s U.S. customers are limited to securities brokers and dealers and banks. Clearstream has customers located in various countries. Indirect access to Clearstream is also available to other institutions that clear through or maintain a custodial relationship with an account holder of Clearstream. Clearstream has established an electronic bridge with Euroclear to facilitate settlement of trades between Clearstream and Euroclear.

The Function of Euroclear. The Euroclear System (“Euroclear”) was created in 1968 in Brussels. Euroclear holds securities and book-entry interests in securities for Euroclear participants and facilitates the clearance and settlement of securities transactions between Euroclear participants, and between Euroclear participants and participants of certain other securities intermediaries through simultaneous electronic book-entry delivery against payment, thereby eliminating the need for physical movement of securities and any risk from lack of simultaneous transfers of securities and cash. Such transactions may be settled in any of various currencies, including United States dollars. Euroclear includes various other services, including, among other things, safekeeping, administration, clearance and settlement, securities lending and borrowing and interfaces with domestic markets in several countries generally similar to the arrangements for cross-market transfers with DTC described below. Euroclear is operated by Euroclear Bank SA/NV. Euroclear participants include central banks and other banks, securities brokers and dealers and other professional financial intermediaries and may include the underwriter of the securitized utility tariff bonds. Indirect access to Euroclear is also available to other firms that clear through or maintain a custodial relationship with a Euroclear participant, either directly or indirectly.

Terms and Conditions of Euroclear. Securities clearance accounts and cash accounts with Euroclear are governed by the Terms and Conditions Governing Use of Euroclear and the related Operating Procedures of Euroclear, and applicable Belgian law (collectively, the “Terms and Conditions”). These Terms and Conditions govern transfers of securities and cash within Euroclear, withdrawals of securities and cash from Euroclear and receipts of payments with respect to securities in Euroclear. All securities in Euroclear are held on a fungible basis without attribution of specific securities to specific securities clearance accounts. Euroclear acts under the Terms and Conditions only on behalf of Euroclear participants and has no record of or relationship with persons holding through Euroclear participants.

The Rules for Transfers Among DTC, Clearstream or Euroclear Participants. Transfers between DTC participants will occur in accordance with DTC rules. Transfers between Clearstream customers or Euroclear participants will occur in the ordinary way in accordance with their applicable rules and operating procedures and will be settled using procedures applicable to conventional securities held in registered form.

Cross-market transfers between persons holding directly or indirectly through DTC, on the one hand, and directly or indirectly through Clearstream customers or Euroclear participants, on the other, will be effected through DTC in accordance with DTC rules on behalf of the relevant European international clearing system by its depositary; provided, however, those cross-market transactions will require delivery of instructions to the relevant European international clearing system by the counterparty in that system in accordance with its rules and procedures and within its established deadlines, which will be based on European time. The relevant European international clearing system will, if the transaction meets its settlement requirements, deliver instructions to its depositary to take action to effect final settlement on its behalf by delivering or receiving securitized utility tariff bonds in DTC and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Clearstream customers and Euroclear participants may not deliver instructions directly to Clearstream’s and Euroclear’s depositaries.

Because of time-zone differences, credits of securities in Clearstream or Euroclear as a result of a transaction with a participant will be made during the subsequent securities settlement processing, dated the business day following the DTC settlement date, and those credits or any transactions in those securities settled

66

##### Table of Contents

during that processing will be reported to the relevant Clearstream customer or Euroclear participant on that business day. Cash received in Clearstream or Euroclear as a result of sales of securities by or through a Clearstream customer or a Euroclear participant to a DTC participant will be received with value on the DTC settlement date but will be available in the relevant Clearstream or Euroclear cash account only as of the business day following settlement in DTC.

DTC will be the Holder of the Securitized Utility Tariff Bonds. Securitized utility tariff bondholders that are not Direct Participants or Indirect Participants but desire to purchase, sell or otherwise transfer ownership of, or other interest in, securitized utility tariff bonds may do so only through Direct Participants and Indirect Participants. In addition, securitized utility tariff bondholders will receive all distributions of principal of and interest on the securitized utility tariff bonds from the trustee through the participants, who in turn will receive them from DTC. Under a book-entry format, securitized utility tariff bondholders may experience some delay in their receipt of payments because payments will be remitted by the trustee to Cede & Co., as nominee for DTC. DTC will forward those payments to its Direct Participants, who thereafter will forward them to Indirect Participants or securitized utility tariff bondholders. It is anticipated that the only “bondholder” will be Cede & Co., as nominee of DTC. The trustee will not recognize securitized utility tariff bondholders as bondholders, as that term is used in the Indenture, and securitized utility tariff bondholders will be permitted to exercise the rights of bondholders only indirectly through the participants, who in turn will exercise the rights of securitized utility tariff bondholders through DTC.

Under the rules, regulations and procedures creating and affecting DTC and its operations, DTC is required to make book-entry transfers of book-entry certificates among participants on whose behalf it acts with respect to the securitized utility tariff bonds and is required to receive and transmit distributions of principal and interest on the securitized utility tariff bonds. Direct Participants and Indirect Participants with whom securitized utility tariff bondholders have accounts with respect to the securitized utility tariff bonds similarly are required to make book-entry transfers and receive and transmit those payments on behalf of their respective securitized utility tariff bondholders. Accordingly, although holders of securitized utility tariff bonds will not possess securitized utility tariff bonds, securitized utility tariff bondholders will receive payments and will be able to transfer their interests.

Because DTC can act only on behalf of participants, who in turn act on behalf of indirect participants and certain banks, the ability of a securitized utility tariff bondholder to pledge securitized utility tariff bonds to persons or entities that do not participate in the DTC system, or otherwise take actions in respect of those bonds, may be limited due to the lack of a physical certificate for those securitized utility tariff bonds.

DTC has advised us that it will take any action permitted to be taken by a securitized utility tariff bondholder under the Indenture only at the direction of one or more participants to whose account with DTC the securitized utility tariff bonds are credited. Additionally, DTC has advised us that it will take those actions with respect to specified percentages of the collateral amount only at the direction of and on behalf of participants whose holdings include interests that satisfy those specified percentages. DTC may take conflicting actions with respect to other interests to the extent that those actions are taken on behalf of participants whose holdings include those interests.

Except as required by law, none of any underwriter, the servicer Atmos Energy, the trustee, us or any other party will have any liability for any aspect of the records relating to or payments made on account of beneficial interests in the certificates held by Cede & Co., as nominee for DTC, or for maintaining, supervising or reviewing any records relating to such beneficial interests.

How Securitized Utility Tariff Bond Payments will be Credited by Clearstream and Euroclear. Distributions with respect to securitized utility tariff bonds held through Clearstream or Euroclear will be credited to the cash accounts of Clearstream customers or Euroclear participants in accordance with the relevant system’s rules and procedures, to the extent received by its depositary. Those distributions will be subject to tax reporting in accordance with relevant U.S. tax laws and regulations. Please read “MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES” in this prospectus. Clearstream or the Euroclear operator, as the case may be, will take any other action permitted to be taken by a securitized utility tariff bondholder under the Indenture on behalf of a

67

##### Table of Contents

Clearstream customer or Euroclear participant only in accordance with its relevant rules and procedures and subject to its depositary’s ability to affect those actions on its behalf through DTC.

Although DTC, Clearstream and Euroclear have agreed to the foregoing procedures in order to facilitate transfers of the securitized utility tariff bonds among participants of DTC, Clearstream and Euroclear, they are under no obligation to perform or continue to perform those procedures, and those procedures may be discontinued at any time.

Definitive Certificated Securitized Utility Tariff Bonds

The Circumstances that will Result in the Issuance of Definitive Certificated Securitized Utility Tariff Bonds. The securitized utility tariff bonds will be issued in fully registered, certificated form to beneficial owners of securitized utility tariff bonds or other intermediaries, rather than to DTC or its nominee, only under the circumstances provided in the Indenture, which includes any event where:

| • |  | we advise the trustee in writing that DTC is no longer willing or able to properly discharge its responsibilities under any letter of representation executed by us in favor of DTC, and we are unable to locate a qualified successor;

| • |  | we, at our option, advise the trustee in writing that we elect to terminate the book-entry system through DTC; or

| • |  | after the occurrence of an event of default under the Indenture, securitized utility tariff bondholders representing at least a majority of the outstanding principal balance of the securitized utility tariff bonds maintained in book-entry form advise us, the trustee and DTC through the financial intermediaries and the DTC participants in writing that the continuation of a book-entry system through DTC, or a successor to DTC, is no longer in the securitized utility tariff bondholders’ best interest.

The Delivery of Definitive Certificated Securitized Utility Tariff Bonds. Upon the occurrence of any event described in the immediately preceding paragraph (unless otherwise specified), we will be required to notify DTC, the trustee, and all affected beneficial owners of securitized utility tariff bonds in writing of the occurrence of the event and of the availability through DTC of definitive certificated securitized utility tariff bonds to such owners of securitized utility tariff bonds. Upon surrender by DTC to the trustee of the global bond or bonds in the possession of DTC that had represented the applicable securitized utility tariff bonds and receipt of instructions for re-registration, the trustee will authenticate and deliver definitive certificated securitized utility tariff bonds to the beneficial owners, and the trustee will recognize the holders of the definitive certificate securitized utility tariff bonds as bondholders under the Indenture.

The Payment Mechanism for Definitive Certificated Securitized Utility Tariff Bonds. Payments of principal of, and interest on, definitive certificated securitized utility tariff bonds will be made by the trustee, as paying agent, in accordance with the procedures set forth in the Indenture. These payments will be made directly to holders of definitive certificated securitized utility tariff bonds in whose names the definitive certificated securitized utility tariff bonds were registered at the close of business on the related record date. The trustee will make the final payment for the securitized utility tariff bonds, however, only upon presentation and surrender of the securitized utility tariff bonds at the office or agency of the trustee specified in the notice given by the trustee of the final payment. The trustee will mail notice of the final payment to the securitized utility tariff bondholders no later than five days prior to the final payment date, specifying the date set for the final payment and the amount of the payment.

The Transfer or Exchange of Definitive Certificated Securitized Utility Tariff Bonds. Definitive certificated securitized utility tariff bonds will be transferable and exchangeable at the offices of the transfer agent and registrar, which will initially be U.S. Bank Trust Company, National Association. No service charge will be imposed for any registration of transfer or exchange, but we and the transfer agent and registrar may require payment of a sum sufficient to cover any tax or other governmental charge imposed in connection with the transfer or exchange.

68

##### Table of Contents

Registration and Transfer of the Securitized Utility Tariff Bonds

We will only issue the securitized utility tariff bonds in definitive form under limited circumstances as described above, which will be transferable and exchangeable as described above under “—Definitive Certificated Securitized Utility Tariff Bonds.” There will be no service charge for any registration or transfer of the securitized utility tariff bonds, but the trustee may require the owner to pay a sum sufficient to cover any tax or other governmental charge.

We will issue the securitized utility tariff bonds in the minimum initial denominations and integral multiples set forth in this prospectus.

The trustee will make payments of interest and principal on each payment date to the securitized utility tariff bondholders in whose names the securitized utility tariff bonds were registered on the applicable record date.

The Security for the Securitized Utility Tariff Bonds

To secure the payment of principal, premium, if any, and interest on, and any other amounts owed in respect of, the securitized utility tariff bonds pursuant to the Indenture, we will grant to the trustee for the benefit of the securitized utility tariff bondholders a security interest in all of our right, title and interest, whether now owned or later acquired, in and to the following collateral, which collectively constitutes the trust estate under the Indenture:

| • |  | the securitized utility tariff property;

| • |  | the securitized utility tariff charges related to the securitized utility tariff property;

| • |  | our rights under the sale agreement;

| • |  | all rights to compel the servicer to file for and obtain periodic adjustments to the securitized utility tariff charges in accordance with the Securitization Act and the financing order;

| • |  | all of our other property related to the securitized utility tariff bonds, other than any cash released to us by the trustee semi-annually from earnings on the capital subaccount;

| • |  | all present and future claims, demands, causes and choses in action in respect of any or all of the foregoing; and

| • |  | all payments on or under and all proceeds in respect of any or all of the foregoing, including all proceeds of the conversion, voluntary or involuntary, into cash or other liquid property of any or all of the foregoing, all cash proceeds, accounts, accounts receivable, general intangibles, notes, drafts, acceptances, chattel paper, checks, deposit accounts, insurance proceeds, condemnation awards, payment intangibles, letter-of-credit rights, investment property, commercial tort claims, documents, rights to payment of any and every kind, and other forms of obligations and receivables, instruments and other property which at any time constitute all or part of or are included in the proceeds of any of the foregoing.

| • |  | amounts deposited with us for payment of costs of issuance with respect to the securitized utility tariff bonds (together with any interest earnings thereon); or

| • |  | proceeds from the sale of the securitized utility tariff bonds that are required to pay (i) the purchase price for the securitized utility tariff property or (ii) upfront financing costs.

K.S.A. § 66-1,245 of the Securitization Act provides that a valid and enforceable security interest in securitized utility tariff property will attach and be perfected by the means set forth in K.S.A. § 66-1,245. Specifically, K.S.A. § 66-1,245 provides that a valid and enforceable security interest in securitized utility tariff property may be created only after the issuance of a financing order, the execution and delivery of a security agreement in connection with issuance of financing instruments such as the securitized utility tariff bonds and the receipt of value for the instruments. The security interest attaches automatically when all of the foregoing conditions are met. Upon perfection by filing a financing statement under K.S.A. § 66-1,245 of the Securitization Act and otherwise in accordance with the UCC, the security interest will be a continuously perfected security interest in the securitized utility tariff property and all proceeds of the property, whether accrued or not, and will have priority in the order of time of perfection and take precedence over any subsequent lien creditor.

The Collection Account for the Securitized Utility Tariff Bonds

Under the Indenture, we will establish a collection account with the trustee or at another eligible institution for the securitized utility tariff bonds. The collection account will be under the sole dominion and exclusive control of the trustee. Funds received from collections of the applicable securitized utility tariff charges will be deposited into the collection account. The collection account for the securitized utility tariff bonds will be divided into the following subaccounts, which need not be separate bank accounts:

| • |  | the general subaccount;

| • |  | the capital subaccount; and

| • |  | the excess funds subaccount.

For administrative purposes, the subaccounts may be established by the trustee as separate accounts that will be recognized individually as subaccounts and collectively as the collection account. Unless otherwise provided in the Indenture, amounts in the collection account for the securitized utility tariff bonds not allocated to any other subaccount by the servicer will be allocated to the general subaccount. Unless the context indicates otherwise, references in this prospectus to the collection account for the securitized utility tariff bonds include all of the subaccounts contained therein. All monies deposited from time to time in the collection account, all deposits therein pursuant to the Indenture, and all investments made in eligible investments with these monies will be held by the trustee in the collection account as part of the collateral. The following institutions are eligible institutions for the establishment of the collection account:

| • |  | the corporate trust department of the trustee so long as the trustee has either (i) a short-term credit rating from Moody’s and Fitch of at least “P-1” and “F1”, respectively or (ii) a long-term credit rating from Moody’s and Fitch of at least “A2” and “A”, respectively, or

| • |  | a depository institution organized under the laws of the United States of America or any state or the District of Columbia or domestic branch of a foreign bank whose deposits are insured by the Federal Deposit Insurance Corporation, (i) which has either (A) a long-term unsecured debt rating of “A2” or higher by Moody’s and “A” or higher by Fitch, or (B) a short-term issuer rating of “P-1” or higher by Moody’s and “F1” or higher by Fitch, or any other long-term, short-term or certificate of deposit rating acceptable to Moody’s and Fitch and (ii) whose deposits are insured by the Federal Deposit Insurance Corporation (FDIC),

provided, however, that if an eligible institution then being utilized for any purposes under the Indenture or the series supplement no longer meets the definition of eligible institution, then the issuing entity shall replace such eligible institution within 60 days of such eligible institution no longer meeting the definition of eligible institution.

If so qualified under clause (i)(A) above, the trustee may be considered an eligible institution for purposes of establishing and maintaining the collection account.

Appropriate Investments for Funds in the Collection Account. So long as no default or event of default has occurred and is continuing, all or a portion of the funds in the collection account for the securitized utility tariff bonds must be invested by the trustee in accordance with the written direction of the servicer in any of the following, each of which is referred to as an eligible investment:

1. | direct obligations of, and obligations fully and unconditionally guaranteed as to timely payment by, the United States of America;

2. | demand deposits, time deposits or certificates of deposit of any depository institution or trust company incorporated under the laws of the United States of America or any state thereof, or any domestic branch of a foreign bank, and subject to supervision and examination by federal or state banking authorities, so long as the commercial paper or other short-term unsecured debt obligations of such depository institution are, at the time of deposit, rated not less than “P-1” and “F1” or their equivalents by each of Moody’s and Fitch, or such lower rating as will not result in the downgrading or withdrawal of the ratings of the securitized utility tariff bonds, provided, however, that if any such depository institution, trust company or domestic branch of a foreign bank no longer meets the requirements set forth above, then the issuing entity shall replace such depository institution, trust company or domestic branch of a foreign bank within 60 days of such depository institution, trust company or domestic branch of a foreign bank no longer meeting such requirements;

3. | commercial paper (including commercial paper of the trustee, acting in its commercial capacity, and other commercial paper issued by Atmos Energy or any of its affiliates) having, at the time of investment or contractual commitment to invest, a rating of at least “P-1” and “F1” or their equivalents by each of Moody’s and Fitch or such lower rating as not result in the downgrading or withdrawal of the ratings of the securitized utility tariff bonds;

4. | investments in money market funds having a rating from Moody’s and, if Fitch provides a rating thereon, Fitch, of “Aaa-mf” and “AAAmmf”, respectively, including funds for which the trustee or any of its affiliates act as investment manager or advisor;

5. | repurchase obligations with respect to any security that is a direct obligation of, or fully guaranteed by, the United States of America or its agencies or instrumentalities, entered into with Eligible Institutions;

6. | repurchase obligations with respect to any security or whole loan entered into with an Eligible Institution or with a registered broker-dealer acting as principal that has either a short-term credit rating from Moody’s and Fitch of at least “P-1” and “F1”, respectively, or a long-term credit rating from Moody’s and Fitch of at least “A2” and “A”, respectively; provided, however, that if any such Eligible Institution or registered broker-dealer no longer meets the requirements set forth above, then we shall replace such Eligible Institution or registered broker-dealer within 60 days of such Eligible Institution or registered broker-dealer no longer meeting such requirements; or

7. | any other investment permitted by each of the rating agencies.

Notwithstanding the foregoing: (a) no investments which mature in 30 days or more will be eligible investments unless the issuer thereof has either a short-term credit rating of at least “P-1” from Moody’s or a long-term unsecured debt rating of at least “A1” from Moody’s and has at least a debt rating of “F1+” or “AA-” from Fitch, (b) no investments described in clauses (2) through (4) above which have maturities of more than 30 days but less than or equal to three months will be eligible investments unless the issuer thereof has a long-term unsecured debt rating of at least “A1” from Moody’s and a short-term credit rating of at least “P-1” from Moody’s, and (c) no investments described in clauses (2) through (4) above which have maturities of more than three months will be eligible investments unless the issuer thereof has a long-term unsecured debt rating of at least “A1” from Moody’s and a short-term credit rating of at least “P-1” from Moody’s.

Remittances to the Collection Account. On each remittance date, the servicer will remit all collected securitized utility tariff charges, any indemnity amounts and any other proceeds of the trust estate securing the securitized utility tariff bonds to the trustee for deposit in the collection account. Indemnity amount means any amount paid

71

##### Table of Contents

by the servicer or Atmos Energy to the trustee, for the trustee or on behalf of the securitized utility tariff bondholders, in respect of indemnification obligations pursuant to the servicing agreement or the sale agreement. Please read “THE SERVICING AGREEMENT” and “THE SALE AGREEMENT” in this prospectus.

General Subaccount. Collected securitized utility tariff charges and any indemnity amounts remitted to the trustee will be deposited into the general subaccount. On each payment date, the trustee will allocate amounts in the general subaccount among the other subaccounts as described under “—How Funds in the Collection Account Will Be Allocated.” Amounts in the general subaccount will be invested in the eligible investments described above.

Capital Subaccount. Upon the issuance of the securitized utility tariff bonds, Atmos Energy will make a capital contribution to us in an amount not to be less than 0.50% of the initial principal amount of the securitized utility tariff bonds, and such payment shall not come from the proceeds of the sale of the securitized utility tariff bonds. We will pay this amount to the trustee for deposit into the capital subaccount which will be invested in eligible investments by the trustee in accordance with the written direction of the servicer. The trustee will draw on amounts in the capital subaccount to the extent that, in allocating funds in accordance with clauses 1 through 8 in “—How Funds in the Collection Account Will Be Allocated,” below, amounts on deposit in the general subaccount and, the excess funds subaccount are insufficient to make scheduled payments on the securitized utility tariff bonds and payments of fees and expenses specified in clauses 1 through 8. The trustee will allocate collected securitized utility tariff charges available on any payment date that are not necessary to pay amounts described in clauses 1 through 8 in “—How Funds in the Collection Account Will Be Allocated,” below, to the capital subaccount in an amount sufficient to replenish any amounts drawn from the capital subaccount (other than distributed investment earnings on the capital subaccount) and any shortfall of investment earnings on the capital subaccount. On each payment date, any excess investment earnings on the capital subaccount above the allowed rate of return shall be allocated to the excess funds subaccount.

Excess Funds Subaccount. The trustee will allocate collected securitized utility tariff charges available on any payment date that are not necessary to pay clauses 1 through 10 in “—How Funds in the Collection Account Will Be Allocated,” below, to the excess funds subaccount. The trustee will invest amounts in the excess funds subaccount in eligible investments in accordance with the written direction of the servicer. On each payment date, the trustee will draw on the excess funds subaccount in allocating funds in accordance with clauses 1 through 10 in “—How Funds in the Collection Account Will Be Allocated,” below, to the extent that amounts on deposit in the general subaccount are insufficient to make scheduled payments on the securitized utility tariff bonds and payments of fees and expenses specified in clauses 1 through 10.

How Funds in the Collection Account Will Be Allocated

Amounts remitted by the servicer to the trustee with respect to the securitized utility tariff bonds, including any amounts received by us relating to the indemnification obligations payable by the seller pursuant to the sale agreement or the servicer pursuant to the servicing agreement and all investment earnings on amounts in the general subaccount of the collection account will be deposited into the general subaccount. Investment earnings on amounts in the capital subaccount (other than excess investment earnings that are allocated to the excess funds subaccount) and the excess funds subaccount will be deposited into the capital subaccount and the excess funds subaccount, respectively.

On each payment date for the securitized utility tariff bonds, the trustee will allocate or pay all amounts on deposit in the general subaccount of the collection account for the securitized utility tariff bonds in the following priority:

1. | payment of the trustee’s fees, plus expenses and any outstanding indemnity amounts not to exceed $200,000 in any 12-month period, provided, however, that such cap shall be disregarded and inapplicable upon the acceleration of the securitized utility tariff bonds following the occurrence of an event of default;

72

##### Table of Contents

2. | payment of the servicing fee with respect to such payment date, plus any unpaid servicing fees for prior payment dates shall be paid to the servicer;

3. | payment of the due and unpaid administration fee, which will be a fixed amount specified in the administration agreement between us and Atmos Energy for such payment date shall be paid to the administrator, and the due and unpaid fees of our independent manager, which will be in an amount specified in an agreement between us and our independent manager for such payment date shall be paid to the independent manager;

4. | payment of all of our other ordinary periodic operating expenses for such payment date not described above shall be paid to the parties, pro rata, to which such operating expenses are owed;

5. | payment of the interest then due on the securitized utility tariff bonds, including any past due interest;

6. | payment of the principal due to be paid on the securitized utility tariff bonds on the final maturity date or acceleration upon an event of default;

7. | payment of the principal then scheduled to be paid on the securitized utility tariff bonds, including any previously unpaid scheduled principal;

8. | payment of any of our remaining unpaid operating expenses and any remaining expenses and indemnity amounts owed pursuant to the basic documents, including all remaining expenses and indemnity amounts owed to the trustee, shall be paid to the parties, pro rata, to which such operating expenses and remaining amounts are owed;

9. | replenishment of the amount, if any, by which the initial balance of the capital subaccount exceeds the amount in the capital subaccount as of such payment date;

10. | the return on the invested capital then due and payable, which shall be the sum of the rate of return payable to Atmos Energy;

11. | allocation of the remainder, if any, to the excess funds subaccount; and

12. | after the securitized utility tariff bonds have been paid in full and discharged, and all of the other foregoing amounts have been paid in full, the balance, together with all amounts in the capital subaccount and the excess funds subaccount of the securitized utility tariff bonds, released to us free and clear of the lien of the Indenture, which funds, less an amount equal to the initial deposit into the capital subaccount plus any unpaid return on invested capital, will be distributed to Atmos Energy and credited to Atmos Energy’s retail customers in the form of a credit to their natural gas bills.

The amount of the annual servicer’s fee referred to in clause 2 above shall be 0.05% of the aggregate initial principal amount of the securitized utility tariff bonds. The amount of the annual administration fee referred to in clause 3 above shall be fixed at $100,000.

Interest means, for any payment date for the securitized utility tariff bonds, the sum, without duplication, of:

| • |  | an amount equal to the interest accrued at the interest rate from the prior payment date or, with respect to the first payment date, the amount of interest accrued since the issuance date;

| • |  | any unpaid interest plus, to the fullest extent permitted by law, any interest accrued on this unpaid interest; and

| • |  | if the securitized utility tariff bonds have been declared due and payable, all accrued and unpaid interest thereon.

Principal means, with respect to any payment date, the sum, without duplication, of:

| • |  | the amount of principal due as a result of the occurrence and continuance of an event of default and acceleration of the securitized utility tariff bonds;

| • |  | the amount of principal due on the final maturity date;

73

##### Table of Contents

| • |  | any unpaid and previously scheduled payments of principal and overdue payments of principal; and

| • |  | the amount of principal scheduled to be paid on such payment date in accordance with the expected sinking fund schedule.

If on any payment date funds in the general subaccount are insufficient to make the allocations or payments contemplated by clauses 1 through 9 of the first paragraph of this subsection with respect to the securitized utility tariff bonds, the trustee will draw from amounts on deposit in the following subaccounts in the following order up to the amount of the shortfall:

1. | from the excess funds subaccount for allocations and payments contemplated in clauses 1 through 9, and

2. | from the capital subaccount for allocations and payments contemplated by clauses 1 through 8.

How Funds in the Subaccounts Will Be Used upon Repayment of the Securitized Utility Tariff Bonds

Upon the payment in full of all securitized utility tariff bonds authorized in the financing order and the discharge of all obligations, including financing costs, all remaining amounts in the collection account (including investment earnings) shall be released by the trustee to us for distribution to Atmos Energy. With regard to the remaining amounts in the collection account (excluding amounts in the capital subaccount), within 30 days after the payment of all obligations (including the final financing costs) payable from those funds, Atmos Energy shall notify the Kansas commission of the amount of such funds available for crediting to the benefit of retail customers. With regard to the amounts in the capital subaccount of the collection account, all such funds shall be released to us for distribution to, and retention by, Atmos Energy. Until such funds are returned by us to Atmos Energy, Atmos Energy may earn a rate of return on its capital investment in us equal to Atmos Energy’s cost of capital, which is 8.396% as of April 30, 2023. Such rate of return shall be paid by us by means of periodic distributions that are funded first by the income earned through investment by the trustee in eligible investments, and second by any deficiency being collected through the true-up adjustments. Any actual earnings in excess of that rate will instead be credited to retail customers.

Reports to Holders of the Securitized Utility Tariff Bonds

On or before each payment date, the trustee shall make available electronically on its reporting website to each of the holders of securitized utility tariff bonds and the Kansas commission a statement provided and prepared by the servicer. This statement will include, to the extent applicable, the following information, as well as any other information so specified in the series supplement, as to the securitized utility tariff bonds with respect to that payment date or the period since the previous payment date, as applicable:

| • |  | the amount of the payment to holders of securitized utility tariff bonds allocable to principal;

| • |  | the amount of the payment to holders of securitized utility tariff bonds allocable to interest;

| • |  | the aggregate outstanding amount of the securitized utility tariff bonds, before and after giving effect to any payments allocated to principal reported above;

| • |  | the difference, if any between the aggregate outstanding amount specified immediately above and the outstanding amount specified in the sinking fund schedule;

| • |  | any other transfers and payments to be made on such payment date, including amounts paid to the trustee and to the servicer; and

| • |  | the amounts on deposit in the capital subaccount and the excess funds subaccount, after giving effect to the foregoing payments.

We and the Trustee May Modify the Indenture

Modifications of the Indenture That Do Not Require Consent of Securitized Utility Tariff Bondholders. Without the consent of any of the holders of the outstanding securitized utility tariff bonds but with prior notice to the rating agencies and, with respect to amendments that would increase ongoing financing costs, with the consent or deemed consent of the Kansas commission (other than with respect to the series supplement establishing the securitized utility tariff bonds), we and the trustee may execute a supplemental indenture for any of the following purposes:

| • |  | to correct or amplify the description of the collateral, or to better assure, convey and confirm unto the trustee the collateral, or to subject additional property to the lien of the Indenture;

| • |  | to evidence the succession, in compliance with the applicable provisions of the Indenture, of another entity to us, and the assumption by any applicable successor of our covenants contained in the Indenture and in the securitized utility tariff bonds;

| • |  | to add to our covenants, for the benefit of the securitized utility tariff bondholders, or to surrender any right or power therein conferred upon us;

| • |  | to convey, transfer, assign, mortgage or pledge any property to or with the trustee;

| • |  | to authorize the appointment of any person for the securitized utility tariff bonds required or advisable with the listing on any stock exchange and otherwise amend the Indenture to incorporate changes requested or required by any governmental authority, stock exchange authority or fiduciary for the securitized utility tariff bonds in connection with such listing.

Additional Modifications to the Indenture that do not Require the Consent of Securitized Utility Tariff Bondholders. We and the trustee may also, without the consent of any of the securitized utility tariff bondholders but, with respect to amendments that would increase ongoing financing costs, with the consent or deemed consent of the Kansas commission, execute one or more other agreements supplemental to the Indenture as long as:

| • |  | the supplemental agreement does not adversely affect in any material respect the interests of any securitized utility tariff bondholder; and

| • |  | the rating agency condition shall have been satisfied with respect thereto.

Any such amendment that may have the effect of increasing ongoing financing costs may be provided by us to the Kansas commission, along with a statement as to the possible effect of the amendment on the ongoing financing costs, and such amendment shall become effective on the later of (i) the date proposed by the parties to the amendment or (ii) 31 days after such submission to the Kansas commission, unless such commission issues an order disapproving the amendment within a 30-day period.

Modifications to the Indenture that Require the Approval of the Securitized Utility Tariff Bondholders.

Any such amendment that may have the effect of increasing ongoing financing costs shall be provided by us to the Kansas commission, along with a statement as to the possible effect of the amendment on the ongoing financing costs, and such amendment shall become effective on the later of (i) the date proposed by the parties to the amendment or (ii) 31 days after such submission to the Kansas commission, unless such commission issues an order disapproving the amendment within a 30-day period. Under no circumstance may the supplemental indenture without the consent of the securitized utility tariff bondholders affected thereby:

| • |  | change the date of payment of any installment of principal of or premium, if any, or interest on the securitized utility tariff bonds, or reduce the principal amount thereof, the bond rate or interest rate thereon or the premium, if any, with respect thereto;

| • |  | change the provisions of the Indenture and the series supplement relating to the application of collections on, or the proceeds of the sale of, the collateral to payment of principal of or premium, if any, or interest on the securitized utility tariff bonds, or change any place of payment where, or the coin or currency in which, any securitized utility tariff bond or any interest thereon is payable;

| • |  | reduce the percentage of the aggregate amount of the outstanding securitized utility tariff bonds, the consent of the securitized utility tariff bondholders of which is required for any supplemental indenture, or the consent of the securitized utility tariff bondholders of which is required for any waiver of compliance with those certain provisions of the Indenture specified therein or of certain defaults specified therein and their consequences provided for in the Indenture;

| • |  | modify any of the provisions of the Indenture in a manner as to affect the calculation of the amount of any payment of interest, principal or premium, if any, due on any securitized utility tariff bond on any payment date (including the calculation of any of the individual components of such calculation) or change the expected sinking fund schedule or expected amortization schedule or final maturity date of the securitized utility tariff bonds;

| • |  | decrease the required capital amount;

| • |  | permit the creation of any lien ranking prior to or on a parity with the lien of the Indenture with respect to any of the collateral for the securitized utility tariff bonds or, except as otherwise permitted or contemplated in the Indenture, terminate the lien of the Indenture on any property at any time subject thereto or deprive the holder of any securitized utility tariff bond of the security provided by the lien of the Indenture;

| • |  | cause any material adverse U.S. federal income tax consequence to us, Atmos Energy, the managers, the trustee or the then-existing securitized utility tariff bondholders; or

| • |  | impair the right to institute suit for the enforcement of the provisions of the Indenture regarding payment or application of funds.

Enforcement of the Sale Agreement, the Administration Agreement and the Servicing Agreement. The Indenture provides that we will take all lawful actions to enforce our rights under the sale agreement, the administration agreement, the servicing agreement and other basic documents. The Indenture also provides that we will take all lawful actions to compel or secure the performance and observance by Atmos Energy, the administrator and the servicer of their respective obligations to us under or in connection with the sale agreement, the administration agreement, the servicing agreement, and other basic documents. So long as no event of default occurs and is continuing, we may exercise any and all rights, remedies, powers and privileges lawfully available to us under or in connection with the sale agreement, the administration agreement, the servicing agreement and other basic documents; provided that such action shall not adversely affect the interests of the securitized utility tariff bondholders in any material respect. However, if we or the servicer propose to amend, modify, waive, supplement, terminate or surrender in any material respect, or agree to any material amendment, modification, supplement, termination, waiver or surrender of, the process for adjusting the securitized utility tariff charges, we must notify the trustee, the securitized utility tariff bondholders and, when required, the Kansas commission in writing of such proposal (or, if pursuant to a request by us, the trustee shall notify the holders of securitized utility tariff bonds of such proposal). In addition, the trustee may consent to this proposal only with the written consent of the holders of a majority of the principal amount of the outstanding securitized utility tariff bonds and only if the rating agency condition is satisfied. In addition, any proposed amendment of the Indenture, the sale agreement or the servicing agreement that would increase ongoing financing costs requires the prior written consent or deemed consent of the Kansas commission.

If an event of default occurs and is continuing, the trustee may, and, at the written direction of the holders of not less than a majority of the outstanding amount of the securitized utility tariff bonds or of the Kansas commission, shall exercise all of our rights, remedies, powers, privileges and claims against Atmos Energy, the administrator and servicer, under or in connection with the sale agreement, administration agreement and servicing agreement, and any right of ours to take this action shall be suspended.

##### Table of Contents

Modifications to the Sale Agreement, the Administration Agreement and the Servicing Agreement. The sale agreement, the administration agreement and the servicing agreement, may be amended, so long as the rating agency condition is satisfied in connection therewith, at any time and from time to time, without the consent of the securitized utility tariff bondholders but with the consent of the trustee and, with respect to amendments that would increase ongoing financing costs, with the consent or deemed consent of the Kansas commission. The trustee shall provide such consent upon receiving evidence of satisfaction of the rating agency condition and evidence that the amendment is in accordance with the terms of the agreement being amended. Furthermore, any amendment to any such agreement that may have the effect of increasing ongoing financing costs shall be provided by us to the Kansas commission, along with a statement as to the possible effect of the amendment on the ongoing financing costs. The amendment shall become effective on the later of (i) the date proposed by the parties to the amendment or (ii) 31 days after such submission to the Kansas commission unless such commission issues an order disapproving the amendment within a 30-day period.

Notification of the Rating Agencies, the Kansas Commission, the Trustee and the Securitized Utility Tariff Bondholders of Any Modification.

If we, Atmos Energy or any other party to the applicable agreement:

| • |  | proposes to amend, modify, waive, supplement, terminate or surrender, or agree to any other amendment, modification, waiver, supplement, termination or surrender of, the terms of the sale agreement or the servicing agreement; or

| • |  | waives timely performance or observance by Atmos Energy under the sale agreement or the servicing agreement;

in each case in a way which would materially and adversely affect the interests of securitized utility tariff bondholders, we must first notify the rating agencies of the proposed action and must promptly notify the trustee, the Kansas commission and the securitized utility tariff bondholders in writing of the proposed action and whether the rating agency condition has been satisfied with respect thereto (or, if pursuant to a request by us, the trustee shall notify the securitized utility tariff bondholders on our behalf). The trustee will consent to this proposed amendment, modification, supplement or waiver only if the rating agency condition is satisfied and only with the written consent of the holders of not less than a majority of the outstanding principal amount of the securitized utility tariff bonds and, if such action would increase ongoing financing costs, the consent of the Kansas commission.

What Constitutes an Event of Default on the Securitized Utility Tariff Bonds

An event of default with respect to the securitized utility tariff bonds is defined in the Indenture as being:

1. | a default in the payment of any interest on any securitized utility tariff bond when the same becomes due and payable and the continuation of this default for five business days;

2. | a default in the payment of the then unpaid principal of the securitized utility tariff bonds on the final maturity date;

3. | a default in the observance or performance of any of our covenants or agreements made in the Indenture, other than those specifically dealt with in clause 1 or 2 above, or any of our representations or warranties made in the Indenture or the series supplement or in any certificate or other writing delivered pursuant to the Indenture or in connection with the Indenture proving to have been incorrect in any material respect as of the time when made, and if such default continues or is not cured for a period of 30 days after the earlier of (a) written notice of the default is given to us by the trustee or to us and the trustee by the holders of at least 25% of the outstanding principal amount of the securitized utility tariff bonds or (b) the date we have actual notice of the default;

4. | the filing of a decree or order for relief by a court having jurisdiction in the premises in respect of us or any substantial part of the collateral in an involuntary case or proceeding under any applicable U.S. federal or

Remedies Available Following an Event of Default. If an event of default with respect to the securitized utility tariff bonds, other than event number 6 above, occurs and is continuing, the trustee or holders holding not less than a majority in principal amount of the securitized utility tariff bonds may declare the unpaid principal balance of securitized utility tariff bonds, together with accrued interest, to be immediately due and payable. This declaration may, under the circumstances specified therein, be rescinded by the holders of a majority in principal amount of the securitized utility tariff bonds. The nature of our business will result in payment of principal upon such a declaration being made as funds become available. Please read “RISK FACTORS—Risks associated with the unusual nature of the securitized utility tariff property—Foreclosure of the trustee’s lien on the securitized utility tariff property might not be practical, and acceleration of the securitized utility tariff bonds before maturity might have little practical effect” and “—You may experience material payment delays or incur a loss on your investment in the securitized utility tariff bonds because the source of funds for payment is limited.”

In addition to acceleration of the securitized utility tariff bonds described above, the trustee may exercise one or more of the following remedies upon an event of default (other than event number 6 above):

1. | the trustee may institute proceedings in its own name and as trustee of an express trust for the collection of all amounts then payable on the securitized utility tariff bonds or under the Indenture with respect to the securitized utility tariff bonds, whether by declaration of acceleration or otherwise, and, subject to the limitations on recovery set forth in the Indenture, enforce any judgment obtained, and collect from us moneys adjudged due, upon the securitized utility tariff bonds;

2. | the trustee may institute proceedings from time to time for the complete or partial foreclosure of the Indenture with respect to the collateral securing the securitized utility tariff bonds;

3. | the trustee may exercise any remedies of a secured party under the UCC or the Securitization Act or any other applicable law and take any other appropriate action to protect and enforce the rights and remedies of the trustee and the holders of securitized utility tariff bonds;

4. | at the written direction of the holders of a majority in the principal amount of the securitized utility tariff bonds, the trustee may either sell all or a portion of the collateral securing the securitized utility tariff bonds or rights or interest therein, at one or more public or private sales called and conducted in any manner permitted by applicable law provided that certain conditions set forth in the Indenture are met, or elect that we maintain possession of all or a portion of the collateral securing the securitized utility tariff bonds pursuant to the terms of the Indenture and continue to apply the securitized utility tariff charges as if there had been no declaration of acceleration; and

79

##### Table of Contents

5. | the trustee may exercise all of our rights, remedies, powers, privileges and claims against the seller, administrator and the servicer under or in connection with the administration agreement, the sale agreement or the servicing agreement.

If event of default number 6 above occurs, the trustee may to the extent allowed by applicable law institute or participate in proceedings necessary to compel performance of or to enforce the pledge of either the State of Kansas or the Kansas commission and to collect any monetary damages incurred by the securitized utility tariff bondholders or the trustee as a result of such event of default. This is the only remedy the trustee may exercise if this event of default has occurred.

When the Trustee Can Sell the Collateral. If the securitized utility tariff bonds have been declared to be due and payable following an event of default, the trustee may, at the written direction of the holders of a majority in principal amount of the securitized utility tariff bonds, either:

| • |  | subject to the paragraph immediately below, sell the collateral securing the securitized utility tariff bonds;

| • |  | elect to have us maintain possession of the collateral securing the securitized utility tariff bonds; or

| • |  | take such other remedial action as the trustee, at the written direction of the holders of a majority in principal amount of the securitized utility tariff bonds then outstanding and declared to have been due and payable, may direct and continue to apply distributions on the collateral securing the securitized utility tariff bonds as if there had been no declaration of acceleration.

The trustee is prohibited from selling the collateral securing the securitized utility tariff bonds following an event of default unless the final payment date of the securitized utility tariff bonds has occurred or the securitized utility tariff bonds have been declared due and payable and:

| • |  | the holders of 100% of the principal amount of the securitized utility tariff bonds consent to the sale;

| • |  | the proceeds of the sale or liquidation are sufficient to pay in full the principal of and premium, if any, and accrued interest on the outstanding securitized utility tariff bonds and all financing costs, including all fees, expenses and indemnities due and owing to the trustee; or

| • |  | the trustee determines that funds provided by the collateral securing the securitized utility tariff bonds would not be sufficient on an ongoing basis to make all payments on the securitized utility tariff bonds as these payments would have become due if the securitized utility tariff bonds had not been declared due and payable, and the trustee obtains the written consent of the holders of at least two-thirds of the aggregate outstanding principal amount of the securitized utility tariff bonds.

Right of Securitized Utility Tariff Bondholders to Direct Proceedings. Subject to the provisions for indemnification and the limitations contained in the Indenture, the holders of not less than a majority in principal amount of the outstanding securitized utility tariff bonds will have the right to direct the time, method and place of conducting any proceeding or any remedy available to the trustee or exercising any trust or power conferred on the trustee; provided that, among other things:

| • |  | this direction does not conflict with any rule of applicable law or with the Indenture or the series supplement and shall not involve the trustee in any personal liability or expense;

| • |  | any direction to the trustee to sell or liquidate any of the collateral securing the securitized utility tariff bonds shall be by the holders of the securitized utility tariff bonds representing not less than 100% of the outstanding securitized utility tariff bonds;

| • |  | so long as the conditions specified in the Indenture have been satisfied and the trustee elects to retain the collateral securing the securitized utility tariff bonds pursuant to the Indenture and elects not to sell or liquidate that collateral, any direction to the trustee to sell or liquidate the collateral securing the securitized utility tariff bonds or any portion thereof by the holders representing less than 100% of the outstanding amount of the securitized utility tariff bonds, shall be of no force and effect; and

80

##### Table of Contents

| • |  | the trustee may take any other action deemed proper by the trustee that is not inconsistent with this direction.

However, in case an event of default occurs and is continuing, the trustee will be under no obligation to exercise any of the rights or powers under the Indenture at the request or direction of any of the holders of the securitized utility tariff bonds if:

| • |  | it reasonably believes it will not be indemnified to its satisfaction against any cost, expense or liabilities; or

| • |  | it determines that this action might materially adversely affect the rights of any securitized utility tariff bondholder not consenting to such action.

Waiver of Default. Prior to acceleration of the maturity of the securitized utility tariff bonds, the holders of a majority in principal amount of the securitized utility tariff bonds may, subject to certain conditions specified in the Indenture, waive any default with respect to the securitized utility tariff bonds. However, they may not waive a default in the payment of principal of or premium, if any, or interest on any of the securitized utility tariff bonds or a default in respect of a covenant or provision of the Indenture that cannot be modified without the waiver or consent of all of the holders of the outstanding securitized utility tariff bonds.

Limitation of Proceedings. Under the Indenture, no securitized utility tariff bondholder will have the right to institute any proceeding, judicial or otherwise, or to avail itself of the right to foreclose on the securitized utility tariff property or otherwise enforce the lien in the securitized utility tariff property pursuant to K.S.A. §66-1,245 of the Securitization Act, unless:

| • |  | the holder previously has given to the trustee written notice of a continuing event of default,

| • |  | the holders of a majority in principal amount of the outstanding securitized utility tariff bonds have made written request of the trustee to institute the proceeding in its own name as trustee;

| • |  | the holder or holders have offered the trustee indemnity satisfactory to the trustee against the costs, expenses and liabilities to be incurred in complying with the request;

| • |  | the trustee for 60 days after its receipt of the notice, request and offer of indemnity has failed to institute the proceeding; and

| • |  | no direction inconsistent with this written request has been given to the trustee during the 60-day period referred to above by the holders of a majority in principal amount of the outstanding securitized utility tariff bonds.

In addition, each of the trustee, the securitized utility tariff bondholders and the servicer will covenant that it will not, prior to the date that is one year and one day after the termination of the Indenture, acquiesce, petition or otherwise invoke or cause us or any manager to invoke against us or against our managers or our member or members any bankruptcy, reorganization or other proceeding under any federal or state bankruptcy or similar law. By purchasing securitized utility tariff bonds, each securitized utility tariff bondholder will be deemed to have made this covenant.

Our Covenants

Consolidation, Merger or Sale of Assets. We will keep in effect our existence, rights and franchises as a limited liability company under Delaware law, provided that we may consolidate with, merge into or convert into another entity or sell substantially all of our assets to another entity if:

We may not, except as contemplated by the Indenture, the sale agreement, the servicing agreement and related documents (or as contemplated by an additional financing order issued by the Kansas commission to Atmos Energy), including our limited liability company agreement, make any loan or advance or credit to any person.

##### Table of Contents

We Must File an Annual Compliance Statement

We will deliver to the trustee, the Kansas commission and each rating agency not later than December 31 of each year (commencing with December 31, 2023), an officer’s certificate stating, as to the responsible officer signing such officer’s certificate, that:

| • |  | a review of our activities during the preceding 12 months ended September 30 (or, in the case of the first such officer’s certificate, since the date of the Indenture) and of performance under the Indenture has been made; and

| • |  | to the best of such responsible officer’s knowledge, based on such review, we have in all material respects complied with all conditions and covenants under the Indenture throughout such period, or, if there has been a default in the compliance of any such condition or covenant, specifying each such default known to the responsible officer and the nature and status thereof.

The Trustee Must Provide an Annual Report to All Securitized Utility Tariff Bondholders

If required by the Trust Indenture Act, the trustee will be required to mail each year to all securitized utility tariff bondholders a brief report. This report may state, in accordance with the requirements of the Trust Indenture Act, among other items:

| • |  | the trustee’s eligibility and qualification to continue as the trustee under the Indenture;

| • |  | any amounts advanced by it under the Indenture;

| • |  | the amount, interest rate and maturity date of specific indebtedness owed by us to the trustee in the trustee’s individual capacity;

| • |  | the property and funds physically held by the trustee; and

| • |  | any action taken by it that materially affects the securitized utility tariff bonds and that has not been previously reported.

What Will Trigger Satisfaction and Discharge of the Indenture

The Indenture will cease to be of further effect with respect to the securitized utility tariff bonds, and the trustee, on our reasonable written demand and at our expense, will execute instruments acknowledging satisfaction and discharge of the Indenture with respect to the securitized utility tariff bonds, when:

| • |  | either all securitized utility tariff bonds which have already been authenticated or delivered, with certain exceptions set forth in the Indenture, have been delivered to the trustee for cancellation or either scheduled final payment date has occurred with respect to all securitized utility tariff bonds that have not been delivered to the trustee for cancellation or the securitized utility tariff bonds will be due and payable on their respective scheduled final payment dates within one year, and we have irrevocably deposited in trust with the trustee cash or U.S. government obligations specified in the Indenture, in an amount sufficient to make payments of principal of and premium, if any, and interest on the securitized utility tariff bonds not theretofore delivered to the trustee for cancellation, ongoing financing costs and all other sums payable to us pursuant to the Indenture with respect to the securitized utility tariff bonds when scheduled to be paid and to discharge the entire indebtedness on those securitized utility tariff bonds not previously delivered to the trustee when due;

| • |  | we have paid or caused to be paid all other sums payable by us under the Indenture with respect to the securitized utility tariff bonds; and

| • |  | we have delivered to the trustee an officer’s certificate, an opinion of external counsel, and if required by the Trust Indenture Act or the trustee, a certificate from a firm of independent certified public accountants, each stating that there has been compliance with the conditions precedent in the Indenture or relating to the satisfaction and discharge of the Indenture with respect to the securitized utility tariff bonds.

Our Legal Defeasance and Covenant Defeasance Options

We may, at any time, terminate:

| • |  | all of our obligations under the Indenture with respect to the securitized utility tariff bonds; or

| • |  | our obligations to comply with some of the covenants in the Indenture, including some of the covenants described under “—Our Covenants.”

The legal defeasance option is our right to terminate at any time our obligations under the Indenture with respect to the securitized utility tariff bonds. The covenant defeasance option is our right at any time to terminate our obligations to comply with some of the covenants in the Indenture. We may exercise the legal defeasance option with respect to the securitized utility tariff bonds notwithstanding our prior exercise of the covenant defeasance option. If we exercise the legal defeasance option, the securitized utility tariff bonds will be entitled to payment only from the funds or other obligations set aside under the Indenture for payment thereof on the scheduled final payment date therefor as described below. The securitized utility tariff bonds will not be subject to payment through acceleration prior to the scheduled final payment date. If we exercise the covenant defeasance option, the final payment of the securitized utility tariff bonds may not be accelerated because of an event of default relating to a default in the observance or performance of our covenants or as described in “—What Constitutes an Event of Default on the Securitized Utility Tariff Bonds” above.

We may exercise the legal defeasance option or the covenant defeasance option with respect to securitized utility tariff bonds only if:

| • |  | we have irrevocably deposited or caused to be irrevocably deposited in trust with the trustee cash and/or U.S. government obligations specified in the Indenture that through the scheduled payments of principal and interest in respect thereof in accordance with their terms are in an amount sufficient to pay principal, interest and premium, if any, on the securitized utility tariff bonds not theretofore delivered to the trustee for cancellation and ongoing financing costs and all other sums payable under the Indenture by us with respect to the securitized utility tariff bonds when scheduled to be paid and to discharge the entire indebtedness on the securitized utility tariff bonds when due;

| • |  | we deliver to the trustee a certificate from a nationally recognized firm of independent registered public accountants expressing its opinion that the payments of principal of and interest on the deposited U.S. government obligations when due and without reinvestment plus any cash deposited in the defeasance subaccount will provide cash at times and in sufficient amounts to pay in respect of the securitized utility tariff bonds principal in accordance with the expected sinking fund schedule therefor, interest when due and ongoing financing costs and all other sums payable by us under the Indenture with respect to the securitized utility tariff bonds;

| • |  | in the case of the legal defeasance option, 95 days pass after the deposit is made and during the 95-day period no default relating to events of our bankruptcy, insolvency, receivership or liquidation occurs and is continuing at the end of the period;

| • |  | no default has occurred and is continuing on the day of this deposit and after giving effect thereto;

| • |  | in the case of an exercise of the legal defeasance option, we shall have delivered to the trustee an opinion of external counsel stating that we have received from, or there has been published by, the Internal Revenue Service a ruling, or since the date of execution of the Indenture, there has been a change in the applicable federal income tax law, and in either case confirming that the holders of the securitized utility tariff bonds will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such legal defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if the legal defeasance had not occurred;

| • |  | in the case of an exercise of the covenant defeasance option, we shall have delivered to the trustee an opinion of external counsel to the effect that the holders of the securitized utility tariff bonds will not

85

##### Table of Contents

| recognize income, gain or loss for U.S. federal income tax purposes as a result of such covenant defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if the covenant defeasance had not occurred;

| • |  | we deliver to the trustee a certificate of one of our officers and an opinion of counsel, each stating that all conditions precedent to the legal defeasance option or the covenant defeasance option, as applicable, have been complied with as required by the Indenture;

| • |  | we deliver to the trustee an opinion of external counsel to the effect that (a) in a case under the Bankruptcy Code in which Atmos Energy (or any of its affiliates, other than us) is the debtor, the court would hold that the deposited cash or U.S. government obligations would not be in the bankruptcy estate of Atmos Energy (or any of its affiliates, other than us, that deposited the moneys or U.S. government obligations), and (b) in the event Atmos Energy (or any of its affiliates, other than us, that deposited the moneys or U.S. government obligations), were to be a debtor in a case under the Bankruptcy Code, the court would not disregard the separate legal existence of Atmos Energy (or any of its affiliates, other than us, that deposited the moneys or U.S. government obligations) and us so as to order substantive consolidation under the Bankruptcy Code of our assets and liabilities with the assets and liabilities of Atmos Energy or such other affiliate; and

| • |  | each rating agency has notified us and the trustee that the exercise of the proposed defeasance option will not result in a downgrade or withdrawal of the then current rating of any then outstanding securitized utility tariff bonds.

No Recourse to Others

No recourse may be taken directly or indirectly, by the holders of the securitized utility tariff bonds with respect to our obligations on the securitized utility tariff bonds, under the Indenture or the series supplement or any certificate or other writing delivered in connection therewith, against (1) us, other than from the securitized utility tariff bond collateral, (2) any owner of a beneficial interest in us (including Atmos Energy) or (3) any shareholder, partner, owner, beneficiary, agent, officer, director or employee of the trustee, the managers or any owner of a beneficial interest in us (including Atmos Energy) in its individual capacity, or of any successor or assign or any of them in their respective individual or corporate capacities, except as any such person may have expressly agreed in writing.

Notwithstanding any provision of the Indenture or the series supplement to the contrary, securitized utility tariff bondholders shall look only to the securitized utility tariff bond collateral with respect to any amounts due to the securitized utility tariff bondholders under the Indenture and the securitized utility tariff bonds, and, in the event such collateral is insufficient to pay in full the amounts owed on the securitized utility tariff bonds, shall have no recourse against us in respect of such insufficiency. Each bondholder by accepting a securitized utility tariff bond specifically confirms the nonrecourse nature of these obligations, and waives and releases all such liability. The waiver and release are part of consideration for issuance of securitized utility tariff bonds.

Governing Law

The Indenture will be governed by the laws of the State of New York, without reference to its conflict of law provisions (except as otherwise noted in the Indenture), provided that the creation, attachment and perfection of any liens created in the securitized utility tariff property or other assets of the trust estate, as well as all rights and remedies of the trustee and the holders with respect to the securitized utility tariff property, shall be governed by the laws of the State of Kansas.

THE TRUSTEE

U.S. Bank Trust Company, National Association, a national banking association (“U.S. Bank Trust Co.”), will be the trustee, and will act as the paying agent and registrar for the securitized utility tariff bonds. U.S. Bank National Association (“U.S. Bank N.A.”) made a strategic decision to reposition its corporate trust business by transferring substantially all of its corporate trust business to its affiliate, U.S. Bank Trust Co., a non-depository trust company (U.S. Bank N.A. and U.S. Bank Trust Co. are collectively referred to herein as “U.S. Bank.”). Upon U.S. Bank Trust Co.’s succession to the business of U.S. Bank N.A., it became a wholly owned subsidiary of U.S. Bank N.A. The trustee will maintain the accounts of the issuing entity in the name of the trustee at U.S. Bank N.A.

U.S. Bancorp, with total assets exceeding $675 billion as of December 31, 2022, is the parent company of U.S. Bank N.A., the fifth largest commercial bank in the United States. As of December 31, 2022, U.S. Bancorp operated over 2,600 branch offices in 26 states. A network of specialized U.S. Bancorp offices across the nation provides a comprehensive line of banking, brokerage, insurance, investment, mortgage, trust and payment services products to consumers, businesses, and institutions.

U.S. Bank has one of the largest corporate trust businesses in the country with office locations in 48 Domestic and 2 international cities. The Indenture will be administered from U.S. Bank’s corporate trust office located at 190 South LaSalle Street, 7th Floor, Chicago, Illinois 60603.

U.S. Bank has provided corporate trust services since 1924. As of December 31, 2022, U.S. Bank was acting as trustee with respect to over 124,000 issuances of securities with an aggregate outstanding principal balance of over $5.6 trillion. This portfolio includes corporate and municipal bonds, mortgage-backed and asset-backed securities and collateralized debt obligations.

The trustee shall make each monthly statement available to the bondholders via the trustee’s internet website at https://pivot.usbank.com. Bondholders with questions may direct them to the trustee’s bondholder services group at (800) 934-6802.

U.S. Bank serves or has served as trustee, paying agent and registrar on several issues of utility rate-payer backed securities.

U.S. Bank N.A. and other large financial institutions have been sued in their capacity as trustee or successor trustee for certain residential mortgage-backed securities (“RMBS”) trusts. The complaints, primarily filed by investors or investor groups against U.S. Bank N.A. and similar institutions, allege the trustees caused losses to investors as a result of alleged failures by the sponsors, mortgage loan sellers and servicers to comply with the governing agreements for these RMBS trusts. Plaintiffs generally assert causes of action based upon the trustees’ purported failures to enforce repurchase obligations of mortgage loan sellers for alleged breaches of representations and warranties, notify securityholders of purported events of default allegedly caused by breaches of servicing standards by mortgage loan servicers and abide by a heightened standard of care following alleged events of default.

U.S. Bank N.A. denies liability and believes that it has performed its obligations under the RMBS trusts in good faith, that its actions were not the cause of losses to investors, that it has meritorious defenses, and it has contested and intends to continue contesting the plaintiffs’ claims vigorously. However, U.S. Bank N.A. cannot assure you as to the outcome of any of the litigation, or the possible impact of these litigations on the trustee or the RMBS trusts.

On March 9, 2018, a law firm purporting to represent fifteen Delaware statutory trusts (the “DST”) that issued securities backed by student loans (the “Student Loans”) filed a lawsuit in the Delaware Court of Chancery against U.S. Bank N.A. in its capacities as indenture trustee and successor special servicer, and three

87

##### Table of Contents

other institutions in their respective transaction capacities, with respect to the DSTs and the Student Loans. This lawsuit is captioned The National Collegiate Student Loan Master Trust I, et al. v. U.S. Bank National Association, et al., C.A. No. 2018-0167-JRS (Del. Ch.) (the “NCMSLT Action”). The complaint, as amended on June 15, 2018, alleged that the DSTs have been harmed as a result of purported misconduct or omissions by the defendants concerning administration of the trusts and special servicing of the Student Loans. Since the filing of the NCMSLT Action, certain Student Loan borrowers have made assertions against U.S. Bank N.A. concerning special servicing that appear to be based on certain allegations made on behalf of the DSTs in the NCMSLT Action.

U.S. Bank N.A. has filed a motion seeking dismissal of the operative complaint in its entirety with prejudice pursuant to Chancery Court Rules 12(b)(1) and 12(b)(6) or, in the alternative, a stay of the case while other prior filed disputes involving the DSTs and the Student Loans are litigated. On November 7, 2018, the Court ruled that the case should be stayed in its entirety pending resolution of the first-filed cases. On January 21, 2020, the Court entered an order consolidating for pretrial purposes the NCMSLT Action and three other lawsuits pending in the Delaware Court of Chancery concerning the DSTs and the Student Loans, which remains pending.

U.S. Bank N.A. denies liability in the NCMSLT Action and believes it has performed its obligations as indenture trustee and special servicer in good faith and in compliance in all material respects with the terms of the agreements governing the DSTs and that it has meritorious defenses. It has contested and intends to continue contesting the plaintiffs’ claims vigorously.

While the legal proceedings discussed above involve certain affiliates of the trustee, none of such legal proceedings are material to the securitized utility tariff bondholders.

The trustee may resign at any time upon 30 days’ notice by so notifying us. The holders of a majority in principal amount of the securitized utility tariff bonds then outstanding may remove the trustee by so notifying the trustee and us in writing (upon 30 days’ written notice) and may appoint a successor trustee. We will remove the trustee by written notice if the trustee ceases to be eligible to continue in this capacity under the Indenture, the trustee becomes a debtor in a bankruptcy proceeding or is adjudged insolvent, a receiver, administrator or other public officer takes charge of the trustee or its property or the trustee becomes incapable of acting. If the trustee gives notice of resignation or is removed or a vacancy exists in the office of trustee for any reason, we will be obligated promptly to appoint a successor trustee eligible under the Indenture. We are responsible, initially, for payment of the expenses associated with any such removal or resignation, but any such expenses will be treated as an operating expense and paid out of the general subaccount on a payment date in accordance with the priority of payments set forth in “Description Of The Securitized Utility Tariff Bonds—How Funds in the Collection Account Will Be Allocated” in this prospectus. No resignation or removal of the trustee will become effective until acceptance of the appointment by a successor trustee. The trustee shall at all times satisfy the requirements of certain provisions of the Trust Indenture Act, as amended, and the Investment Company Act of 1940, as amended, and have a combined capital and surplus of at least $50 million and a long-term debt rating from each of Moody’s and Fitch in one of its generic rating categories that specifies investment grade. If the trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business or assets to, another entity, the resulting, surviving or transferee entity shall without any further action be the successor trustee; provided, however, that if such successor trustee is not eligible under the Indenture, the successor trustee will be replaced in accordance with the terms of the Indenture. We and our affiliates may, from time to time, maintain various banking, investment banking and trust relationships with the trustee and its affiliates. Please read “THE SALE AGREEMENT” and “THE SERVICING AGREEMENT” in this prospectus for further information.

The trustee shall not be liable for any action it takes or omits to take in good faith that it believes to be authorized or within its rights or powers, provided that its conduct does not constitute willful misconduct, negligence or bad faith. The trustee shall not be deemed to have notice or knowledge of any default or event of default (other than a payment default) unless a responsible officer of the trustee has actual knowledge thereof or

88

##### Table of Contents

the trustee has received written notice thereof pursuant to the Indenture. The trustee shall not be required to take any action it is directed to take under the Indenture if the trustee determines in good faith that the action so directed is inconsistent with the Indenture, any other basic document or applicable law, or would involve the trustee in personal liability. We have agreed to indemnify the trustee and its officers, directors, employees and agents against any and all cost, damage, liability, tax or expense (including reasonable attorney’s fees and expenses) incurred by it in connection with the administration and enforcement of the Indenture (including the enforcement of the indemnification obligations therein), the series supplement and the other basic documents and the performance of its duties under the Indenture, the series supplement and the other basic documents, provided that we are not required to pay any expense or indemnify against any loss, liability or expense incurred by the trustee through the trustee’s own willful misconduct, negligence or bad faith. Please read “PROSPECTUS SUMMARY OF TERMS—Priority of Payments” and “DESCRIPTION OF THE SECURITIZED UTILITY TARIFF BONDS—How Funds in the Collection Account Will Be Allocated” in this prospectus for further information.

We, Atmos Energy and our respective affiliates may from time to time enter into normal banking and trustee relationships with U.S. Bank Trust Company, National Association and its affiliates. U.S. Bank Trust Company, National Association and its affiliates, among other relationships, are (i) lenders under Atmos Energy’s revolving credit facility, (ii) the trustee and paying agent under the indentures governing various Atmos Energy debt securities and (iii) placement agents under Atmos Energy’s commercial paper program. No relationships currently exist between Atmos Energy, us and our respective affiliates, on the one hand, and U.S. Bank Trust Company, National Association and its affiliates, on the other hand, that would be outside the ordinary course of business or on terms other than would be obtained in an arm’s length transaction with an unrelated third party.

WEIGHTED AVERAGE LIFE AND YIELD CONSIDERATIONS

FOR THE SECURITIZED UTILITY TARIFF BONDS

The rate of principal payments, the amount of each interest payment and the actual final payment date of the securitized utility tariff bonds and the weighted average life thereof will depend primarily on the timing of receipt of collected securitized utility tariff charges by the trustee and the true-up mechanism. The aggregate amount of collected securitized utility tariff charges and the rate of principal amortization on the securitized utility tariff bonds will depend, in part, on the number of retail customers and the rate of delinquencies and write-offs. The securitized utility tariff charges are required to be adjusted from time to time based in part on the actual rate of collected securitized utility tariff charges. However, we can give no assurance that the servicer will be able to forecast accurately the actual number of retail customers and the rate of delinquencies and write-offs or implement adjustments to the securitized utility tariff charges that will cause collected securitized utility tariff charges to be received at any particular rate. Please read “RISK FACTORS—Servicing risks,” “—Other risks associated with an investment in the securitized utility tariff bonds” and “ATMOS ENERGY’S FINANCING ORDER—True-Ups” in this prospectus.

If the servicer receives securitized utility tariff charges at a slower rate than expected, the securitized utility tariff bonds may be retired later than expected. Except in the event of the acceleration of the final payment date of the securitized utility tariff bonds after an event of default, however, the securitized utility tariff bonds will not be paid at a rate faster than that contemplated in the expected amortization schedule of the securitized utility tariff bonds even if the receipt of collected securitized utility tariff charges is accelerated. Instead, receipts in excess of the amounts necessary to amortize the securitized utility tariff bonds in accordance with the applicable expected amortization schedule, to pay interest and related fees and expenses and to fund subaccounts of the collection account will be allocated to the excess funds subaccount. Acceleration of the final maturity date after an event of default in accordance with the terms thereof will result in payment of principal earlier than the scheduled final payment date. A payment on a date that is earlier than forecast might result in a shorter weighted average life, and a payment on a date that is later than forecast might result in a longer weighted average life. In addition, if a larger portion of the delayed payments on the securitized utility tariff bonds is received in later years, the securitized utility tariff bonds may have a longer weighted average life.

Weighted Average Life Sensitivity

Weighted average life refers to the average amount of time from the date of issuance of a security until each dollar of principal of the security has been repaid to the investor. The rate of principal payments on the securitized utility tariff bonds, the aggregate amount of each interest payment on the securitized utility tariff bonds and the actual final payment date of the securitized utility tariff bonds will depend on the timing of the servicer’s receipt of securitized utility tariff charges from Atmos Energy’s retail customers. Changes in the expected weighted average life of the securitized utility tariff bonds in relation to variances in actual retail customer counts from forecast levels are shown below.

|  |  |  |  | -5% ( Standard Deviations from Mean) |  | -15% ( Standard Deviations from Mean)
Tranche |  | Expected Weighted Average Life (Years) |  |  | Weighted Average Life (Years) |  | Change (Days) |  | Weighted Average Life (Years) |  | Change (Days)
A |  |  |  |  |  |

For the purposes of preparing the chart above, the following assumptions, among others, have been made: (i) the forecast error is constant over the life of the securitized utility tariff bonds and is equal to an overestimate of retail customer counts of 5% ( standard deviations from the mean) or 15% ( standard deviations from the mean) as stated in the chart above, (ii) the servicer makes timely and accurate filings to true-up the securitized utility tariff charges semi-annually, (iii) retail customers remit all securitized utility tariff

charges 30 days after such charges are billed, (iv) the securitized utility tariff bonds are issued on , 2023, (v) there is no acceleration of the final maturity date of the securitized utility tariff bonds, and (vi) operating expenses are equal to projections. There can be no assurance that the weighted average lives of the securitized utility tariff bonds will be as shown above.

ESTIMATED ANNUAL FEES AND EXPENSES

Estimated initial annual fees and expenses payable from the securitized utility tariff charges are shown below. For the priorities in application of funds under the Indenture and the series supplement, please refer to “DESCRIPTION OF THE SECURITIZED UTILITY TARIFF BONDS—How Funds in the Collection Account Will Be Allocated” in this prospectus.

As set forth in the table below, we are obligated to pay fees to the trustee, Atmos Energy, as servicer, Atmos Energy, as administrator and our independent manager. We are also obligated to pay Atmos Energy an annual return on its invested capital. The following table illustrates these arrangements:

Recipient |  | Source of payment |  | Estimated fees and expenses payable
Trustee |  | Securitized utility tariff charges and investment earnings |  | $15,000 per annum, plus certain additional expenses and indemnities, if applicable
Servicer |  | Securitized utility tariff charges and investment earnings |  | $47,500 per annum (so long as Atmos Energy is servicer), payable in installments on each payment date, plus reimbursable expenses
Administrator |  | Securitized utility tariff charges and investment earnings |  | $100,000 per annum (so long as Atmos Energy is servicer), payable in installments on each payment date, plus reimbursable expenses
Independent manager |  | Securitized utility tariff charges and investment earnings |  | $3,000 per annum
Atmos Energy return on invested capital |  | Securitized utility tariff charges and investment earnings |  | $39,881 per annum

Pursuant to the financing order, Atmos Energy’s return on the invested capital (Atmos Energy’s capital contribution which has been deposited into the capital subaccount) is equal to Atmos Energy’s cost of capital, which is currently 8.396% as of April 30, 2023.

Pursuant to the servicing agreement, if Atmos Energy or any of its affiliates is not the servicer, an amount agreed upon by the successor servicer and the trustee, provided, that the fee will not, unless the Kansas commission consents, exceed 0.60% of the initial principal amount of the securitized utility tariff bonds on an annualized basis.

The securitized utility tariff charges will also be used by the trustee for the payment of our other financing costs and expenses relating to the securitized utility tariff bonds, such as accounting and audit fees, rating agency fees and legal fees.

THE SALE AGREEMENT

The following summary describes particular material terms and provisions of the sale agreement pursuant to which we will purchase the securitized utility tariff property from Atmos Energy. We have filed the form of the sale agreement with the SEC as an exhibit to the registration statement of which this prospectus forms a part, and we urge you to read such document in its entirety.

Atmos Energy’s Sale and Assignment of the Securitized Utility Tariff Property

In connection with the issuance of the securitized utility tariff bonds, Atmos Energy, as the seller, will offer and sell the securitized utility tariff property to us pursuant to the terms and conditions of the sale agreement. The sale of the securitized utility tariff property to us by Atmos Energy will be financed through the corresponding issuance of the securitized utility tariff bonds. Pursuant to the sale agreement, Atmos Energy will sell, transfer, assign, set over and otherwise convey to us concurrently with the issuance and sale of the securitized utility tariff bonds to the underwriter, without recourse, except as expressly provided therein, all its rights, titles and interests in and to the securitized utility tariff property. The securitized utility tariff property will represent all rights and interests of Atmos Energy under the financing order that are sold and transferred to us pursuant to the sale agreement and the related bill of sale, including the right to impose, bill, charge, collect and receive the securitized utility tariff charges authorized in the financing order with respect to the securitized utility tariff bonds, to obtain periodic adjustments to such charges as provided in the financing order and all revenues, collections, claims, rights to payments, payments, money or proceeds arising from the foregoing rights and interests. The securitized utility tariff property does not include the rights of Atmos Energy to earn and receive a rate of return on its invested capital in us, to receive administration and servicer fees or to use Atmos Energy’s proceeds from the sale of the securitized utility tariff property to us. We will apply the net proceeds that we receive from the sale of the securitized utility tariff bonds to the purchase of the securitized utility tariff property.

As provided by the Securitization Act, our purchase of the securitized utility tariff property from Atmos Energy will be pursuant to the sale agreement, which will expressly provide that such transfer is a sale, will be a true sale, and is not a secured transaction, and title and ownership to the securitized utility tariff property will pass to us. Under the Securitization Act, such sale will constitute a true sale under state law whether or not:

| • |  | we have any recourse against Atmos Energy (except that any such recourse cannot arise from the inability or failure of one or more of Atmos Energy’s retail customers to timely pay all or a portion of the securitized utility tariff charge),

| • |  | Atmos Energy retains any equity interest in the securitized utility tariff property under state law;

| • |  | Atmos Energy acts as a collector of the securitized utility tariff charges; or

| • |  | Atmos Energy treats the transfer as a financing for tax, financial reporting or other purposes.

The Securitization Act provides that a valid and enforceable security interest in securitized utility tariff property will attach only after the issuance of a financing order, the execution and delivery of a security agreement in connection with the issuance of the securitized utility tariff bonds, the debtor has rights in the securitized utility tariff property or the right to transfer rights in the securitized utility tariff property and the receipt of value for the securitized utility tariff bonds. The security interest attaches automatically at the time when all of the foregoing conditions have been met.

Upon the issuance of a financing order, the execution and delivery of the related sale agreement and bill of sale and the filing of a financing statement under the Securitization Act, our purchase of the securitized utility tariff property from Atmos Energy will be perfected as against all third persons, including subsequent judicial or other lien creditors.

The records and computer systems of Atmos Energy will reflect the sale and assignment of Atmos Energy’s rights and interests under the financing order to us. However, we expect that the securitized utility tariff bonds

93

##### Table of Contents

will be reflected as debt on Atmos Energy’s financial statements. In addition, we anticipate that the securitized utility tariff bonds will be treated as debt of Atmos Energy for federal income tax purposes. Please read “MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES.”

| • |  | as of the issuance date, the representations and warranties of Atmos Energy in the sale agreement must be true and correct in all material respects and no material breach by Atmos Energy of its covenants in the sale agreement shall exist, and no default by the servicer shall have occurred and be continuing under the servicing agreement, as certified by Atmos Energy;

| • |  | as of the issuance date, we must have sufficient funds available to pay the purchase price for the securitized utility tariff property to be conveyed, all conditions to the issuance of the securitized utility tariff bonds to purchase the securitized utility tariff property set forth in the Indenture must have been satisfied or waived, and Atmos Energy is not insolvent and will not have been made insolvent by the sale of the securitized utility tariff property and Atmos Energy is not aware of any pending insolvency with respect to itself;

| • |  | on or prior to the issuance date, Atmos Energy must have taken all action required under the Securitization Act, the financing order and other applicable law for us to have ownership of the securitized utility tariff property, free and clear of all liens other than liens created by us pursuant to the Indenture; and we or the servicer, on our behalf, must have taken any action required for us to grant the trustee a first priority perfected security interest in the collateral securing the securitized utility tariff bonds and maintain such security interest as of the issuance date (including all actions required under the Securitization Act, the financing order and the UCC);

| • |  | Atmos Energy must deliver to each rating agency and to us any opinion of counsel requested by the ratings agencies;

| • |  | Atmos Energy must deliver to the trustee and to us an officers’ certificate confirming the satisfaction of each of these conditions as relevant; and

| • |  | we have received the purchase price in funds immediately available on the issuance date.

Atmos Energy’s Representations and Warranties

3. | a. | Atmos Energy is the sole owner of all the rights and interests under the financing order being sold to us on the issuance date,

| b. | on the issuance date, immediately upon the sale under the sale agreement, the securitized utility tariff property will have been validly sold, assigned, transferred set over and conveyed to us free and clear of all liens (except for any lien created by us under the basic documents in favor of the securitized utility tariff bondholders and in accordance with the Securitization Act), and

| c. | all actions or filings (including filings with the Kansas Secretary of State in accordance with the rules prescribed under the Securitization Act) necessary in any jurisdiction to give us a perfected ownership interest (subject to any lien created by us under the basic documents in favor of the securitized utility tariff bondholders, and in accordance with the Securitization Act) in the securitized utility tariff property and to grant to the trustee a first priority perfected security interest in the securitized utility tariff property, free and clear of all liens of Atmos Energy or anyone else (except for any lien created by us under the basic documents in favor of the securitized utility tariff bondholders and in accordance with the Securitization Act) have been taken or made;

4. | the financing order has been issued by the Kansas commission in accordance with the Securitization Act, the financing order and the process by which it was issued comply with all applicable laws, rules and regulations of the State of Kansas, including the Securitization Act, and the financing order is final, non-appealable and in full force and effect;

5. | as of the date of issuance of the securitized utility tariff bonds, the securitized utility tariff bonds will be entitled to the protections provided by the Securitization Act and the financing order, the issuance advice letter and the securitized utility tariff charges authorized therein will have become irrevocable and not subject to reduction, impairment or adjustment by further action of the Kansas commission, except for changes made pursuant to the adjustment mechanism authorized under the Securitization Act. The issuance advice letter and the form of tariff have been filed in accordance with the financing order. The initial securitized utility tariff charges and the final terms of the securitized utility tariff bonds set forth in the issuance advice letter have become effective. No other approval, authorization, consent, order or other action of, or filing with any governmental authority is required in connection with the creation of the securitized utility tariff property, except those that have been obtained or made;

6. | a. | under the Securitization Act, the State of Kansas has pledged that it will not alter the provisions of the part of the Securitization Act which authorizes the Kansas commission to create an irrevocable contract right or chose in action by the issuance of a financing order, to create securitized utility tariff property, and to make the securitized utility tariff charges imposed by a financing order irrevocable, binding and nonbypassable charges, take or permit any action that impairs or would impair the value of the securitized utility tariff property or the security for the securitized utility tariff bonds or revise the securitized utility tariff costs for which recovery is authorized, impair the rights and remedies of the bondholders, assignees and other financing parties in any way, or except for changes made pursuant to the adjustment mechanism authorized under the Securitization Act, reduce, alter or impair the related

##### Table of Contents

| securitized utility tariff charges until the principal, interest and premium, if any, and any other charges incurred and contracts to be performed in connection with the securitized utility tariff bonds, have been paid and performed in full,

| b. | under the laws of the State of Kansas and the federal laws of the United States, (x) a reviewing court of competent jurisdiction would hold that the State of Kansas could not constitutionally take any action of a legislative character, including the repeal or amendment of the Securitization Act, which would substantially limit, alter or impair the securitized utility tariff property or other rights vested in the securitized utility tariff bondholders pursuant to the financing order, or substantially limit, alter, impair or reduce the value or amount of the securitized utility tariff property, unless that action is a reasonable and necessary exercise of the State of Kansas’s sovereign powers based on reasonable conditions and of a character reasonable and appropriate to the emergency or other significant and legitimate public purpose justifying that action, and, (y) under the Takings Clauses of the State of Kansas and United States Constitutions, the State of Kansas could not repeal or amend the Securitization Act or take any other action in contravention of its pledge referred to in subsection (a) above without paying just compensation to the securitized utility tariff bondholders, as determined by a court of competent jurisdiction, if doing so would constitute a permanent appropriation of a substantial property interest of the securitized utility tariff bondholders in the securitized utility tariff property and deprive the securitized utility tariff bondholders of their reasonable expectations arising from their investments in the securitized utility tariff bonds; however, there is no assurance that, even if a court were to award just compensation, it would be sufficient to pay the full amount of principal and interest on the securitized utility tariff bonds, and

| c. | under the laws of the United States Constitution, a Kansas state court reviewing an appeal of Kansas commission action of a legislative character would conclude that the Kansas commission pledge (i) creates a binding contractual obligation of the State of Kansas for purposes of the contract clause of the United States, and (ii) the Kansas commission could not take any action of a legislative character, including the rescission or amendment of the financing order, which violates the Kansas commission pledge in a manner that substantially reduces, limits or impairs the value of the securitized utility tariff property or the securitized utility tariff charges, prior to the time that the securitized utility tariff bonds are paid in full and discharged, unless the Kansas commission action clearly is exercised for a public end and is reasonably necessary to the accomplishment of that public end so as not to be arbitrary, capricious or an abuse of authority. There is no assurance, however, that even if a court were to award just compensation it would be sufficient to pay the full amount of principal and interest on the securitized utility tariff bonds;

7. | there is no order by any court providing for the revocation, alteration, limitation or other impairment of the Securitization Act, the financing order or issuance advice letter, the securitized utility tariff property or the securitized utility tariff charges or any rights arising under any of them or that seeks to enjoin the performance of any obligations under the financing order;

8. | under the laws of the State of Kansas and the federal laws of the United States in effect on the issuance date, no other approval, authorization, consent, order or other action of, or filing with any court, federal or state regulatory body, administrative agency or governmental instrumentality is required in connection with the creation or transfer of Atmos Energy’s rights and interests related to the securitized utility tariff bonds under the financing order and our purchase of the securitized utility tariff property from Atmos Energy, except those that have been obtained or made;

9. | based on information available to Atmos Energy on the issuance date, the assumptions used in calculating the securitized utility tariff charges in the issuance advice letter are reasonable and made in good faith; however, notwithstanding the foregoing, Atmos Energy makes no representation or warranty, express or implied, that billed securitized utility tariff charges will be actually collected from retail customers, or that amounts actually collected arising from the securitized utility tariff charges will in fact be sufficient to meet the payment obligations on the securitized utility tariff bonds or that the assumptions used in calculating such securitized utility tariff charges will in fact be realized;

| d. | if Atmos Energy enters into a sale agreement selling to any other affiliate property consisting of nonbypassable charges payable by Atmos Energy’s retail customers in the State of Kansas comparable to those sold by Atmos Energy pursuant to the sale agreement, the rating agency condition will be satisfied with respect to the securitized utility tariff bonds prior to or coincident with such sale and Atmos Energy shall enter into an intercreditor agreement with us, the indenture trustee, the issuing entity of such additional bonds and the trustee for such additional bonds; and

| e. | neither Atmos Energy nor a subsidiary of Atmos Energy will issue bonds similar to the securitized utility tariff bonds or other bonds supported by nonbypassable charges payable by Atmos Energy’s retail customers in the State of Kansas comparable to those sold by Atmos Energy pursuant to the sale agreement without the rating agency condition being satisfied with respect to the securitized utility tariff bonds prior to or coincident with such issuance;

8. | Atmos Energy agrees that, upon the sale by Atmos Energy of all of its rights and interests related to the securitized utility tariff property to us pursuant to the sale agreement to the fullest extent permitted by law, including applicable Kansas commission regulations and the Securitization Act, we shall have all of the rights originally held by Atmos Energy with respect to the securitized utility tariff property, including the right (subject to the terms of the servicing agreement) to exercise any and all rights and remedies to collect any amounts payable by any retail customer in respect of the securitized utility tariff property, notwithstanding any objection or direction to the contrary by Atmos Energy (and Atmos Energy agrees not to make any such objection or to take any such contrary action) and any payment to the servicer by any person responsible for remitting securitized utility tariff charges to the servicer under the terms of the financing order or the Securitization Act or the rate schedules in the form of tariff shall discharge such person’s obligations in respect of the securitized utility tariff property to the extent of such payment, notwithstanding any objection or direction to the contrary by Atmos Energy;

| financing order by Atmos Energy to us, and shall notify the trustee of the institution of any such action. Atmos Energy agrees to take such legal or administrative actions, including defending against or instituting and pursuing legal actions and appearing or testifying at hearings or similar proceedings, in each case as may be reasonably necessary:

| a. | to protect us and the securitized utility tariff bondholders from claims, state actions or other actions or proceedings of third parties which, if successfully pursued, would result in a breach of any representation described above under the caption “—Atmos Energy’s Representations and Warranties;” or

| b. | so long as Atmos Energy is also the servicer, to block or overturn any attempts to cause a repeal of, modification of or supplement to the Securitization Act, the financing order, the issuance advice letter or the rights of holders of securitized utility tariff bonds by legislative enactment (including any action of the Kansas commission of a legislative character) or constitutional amendment that would be materially adverse to us, the trustee or the securitized utility tariff bondholders. The costs of any such actions or proceedings would be reimbursed by us to Atmos Energy from amounts on deposit in the collection account as an operating expense in accordance with the terms of the Indenture.

11. | so long as any of the securitized utility tariff bonds are outstanding, Atmos Energy will pay all material taxes, assessments and governmental charges imposed upon it or any of its properties or assets or with respect to any of its franchises, businesses, income or property before any penalty accrues thereon if the failure to pay any such taxes, assessments and governmental charges would, after any applicable grace periods, notices or other similar requirements, result in a lien on the securitized utility tariff property; provided that no such tax need be paid if Atmos Energy or any of its affiliates is contesting the same in good faith by appropriate proceedings promptly instituted and diligently conducted and if Atmos Energy or such affiliate has established appropriate reserves as shall be required in conformity with generally accepted accounting principles;

12. | Atmos Energy will comply with all filing requirements imposed upon it in its capacity as seller of the securitized utility tariff property under the financing order, including making any post-closing filings;

13. | even if the sale agreement or the Indenture providing for the securitized utility tariff bonds is terminated, Atmos Energy will not, prior to the date that is one year and one day after the termination of the Indenture, petition or otherwise invoke or cause us to invoke the process of any court or federal or state regulatory body, administrative agency or governmental instrumentality for the purpose of commencing or sustaining an involuntary case against us under any federal or state bankruptcy, insolvency or similar law or appointing a receiver, liquidator, assignee, trustee, custodian, sequestrator or other similar official of ours, or any substantial part of the property of ours or ordering the winding up or liquidation of our affairs.

For the avoidance of doubt, any breach which would adversely affect scheduled payments on the securitized utility tariff bonds will be deemed to be a material breach;

17. | Atmos Energy shall use the proceeds of the sale of the securitized utility tariff property in accordance with the financing order and the Securitization Act; and

101

##### Table of Contents

18. | Upon the reasonable request of us, Atmos Energy shall execute and deliver such further instruments and do such further acts as may be reasonably necessary to carry out more effectually the provisions and purposes of the sale agreement.

Atmos Energy’s Obligation to Indemnify Us and the Trustee and to Take Legal Action

Under the sale agreement, Atmos Energy is obligated to indemnify us and the trustee, for itself and on behalf of the securitized utility tariff bondholders and related parties specified therein, against:

1. | any and all taxes, other than any taxes imposed on the securitized utility tariff bondholders solely as a result of their ownership of the securitized utility tariff bonds, that may at any time be imposed on or asserted against any of those persons under existing law as of the issuance date as a result of the sale and assignment of Atmos Energy’s rights and interests under the financing order by Atmos Energy to us, the acquisition or holding of the securitized utility tariff property by us or the issuance and sale by us of the securitized utility tariff bonds, including any sales, gross receipts, tangible personal property, privilege, franchise or license taxes, but excluding any taxes imposed as a result of a failure of that person to properly withhold or remit taxes imposed with respect to payments on any securitized utility tariff bond, in the event and to the extent such taxes are not recoverable as financing costs, it being understood that the securitized utility tariff bondholders will be entitled to enforce their rights against Atmos Energy solely through a cause of action brought for their benefit by the trustee in accordance with the terms of the Indenture; and

2. | any and all liabilities, obligations, claims, actions, suits or payments of any kind whatsoever that may be imposed on or asserted against any such person, which may include, without limitation, an amount equal to principal and interest on the securitized utility tariff bonds as a measure of Atmos Energy’s indemnification obligations, together with any reasonable costs and expenses incurred by that person, in each case as a result of Atmos Energy’s breach of any of its representations, warranties or covenants contained in the sale agreement.

However, Atmos Energy is not required to indemnify the trustee or related parties against any liability, obligation, claim, action, suit or payment incurred by them through their own willful misconduct, negligence or bad faith. Atmos Energy is not required to indemnify a party for any amount paid or payable by such party in the settlement of any action, proceeding or investigation without the prior written consent of Atmos Energy which consent shall not be unreasonably withheld.

These indemnification obligations will rank equally in right of payment with other general unsecured obligations of Atmos Energy. The indemnities described above will survive the resignation or removal of the trustee and the termination of the sale agreement and include reasonable fees and expenses of investigation and litigation (including reasonable attorneys’ fees and expenses). The representations and warranties described above under the caption “—Atmos Energy’s Representations and Warranties” are made under existing law as in effect as of the date of issuance of the securitized utility tariff bonds. Atmos Energy will not indemnify any party for any changes in law after the issuance of the securitized utility tariff bonds or for any liability resulting solely from a downgrade in the ratings on the securitized utility tariff bonds.

Atmos Energy’s Limited Obligation to Undertake Legal Action. As described in clause 10 above under “—Atmos Energy’s Covenants,” the sale agreement will require Atmos Energy to institute any action or proceeding reasonably necessary to compel performance by the Kansas commission or the State of Kansas of any of their obligations or duties under the Securitization Act, the financing order or the issuance advice letter with respect to the securitized utility tariff property. Except for the foregoing and subject to Atmos Energy’s further covenant to fully preserve, maintain and protect our interests in the securitized utility tariff property and security interest of the trustee in the securitized utility tariff property, Atmos Energy will not be under any obligation to appear in, prosecute or defend any legal action that is not incidental to its obligations under the sale agreement and that in its opinion may involve it in any expense or liability.

Successors to Atmos Energy

The sale agreement will provide that any person which succeeds by merger, conversion, consolidation, sale or other similar transaction to all or substantially all of the natural gas utility business in the state of Kansas of Atmos Energy will be the successor to Atmos Energy with respect to Atmos Energy’s ongoing obligations under the sale agreement without the execution or filing of any document or any further act by any of the parties to the sale agreement. The sale agreement will further require that:

| • |  | immediately after giving effect to any transaction referred to in this paragraph, no representation, warranty or covenant made by Atmos Energy in the sale agreement will have been breached in any material respect, and no servicer default, and no event that, after notice or lapse of time, or both, would become a servicer default will have occurred and be continuing;

| • |  | the rating agencies specified in the sale agreement will have received prior written notice of the transaction; and

| • |  | officers’ certificates and opinions of counsel specified in the sale agreement will have been delivered to us and the trustee.

Amendment

The sale agreement may be amended in writing by the parties thereto, if notice of the amendment is provided by us to each rating agency and the rating agency condition has been satisfied, with the consent of the trustee and, with respect to amendments that would increase ongoing financing costs, the consent or deemed consent of the Kansas commission, provided that any such amendment may not adversely affect the interest of any securitized utility tariff bondholder in any material respect without the consent of securitized utility tariff bondholders, in its capacity as such, representing not less than a majority of the outstanding amount of the securitized utility tariff bonds.

THE SERVICING AGREEMENT

The following summary describes the material terms and provisions of the servicing agreement pursuant to which the servicer will undertake to service the securitized utility tariff property. We have filed the form of the servicing agreement with the SEC as an exhibit to the registration statement of which this prospectus forms a part, and we urge you to read such document in its entirety.

Servicing Procedures

General. The servicer, as our agent, will manage, service, and administer in respect of the securitized utility tariff property. The servicer’s duties will include:

| • |  | calculating customer counts, billing the securitized utility tariff charges, collecting such amounts from retail customers and remitting all collections in respect of the securitized utility tariff property;

| • |  | responding to inquiries by retail customers, the Kansas commission or any other governmental authority with respect to the securitized utility tariff property or the securitized utility tariff charges;

| • |  | investigating and handling delinquencies (and furnishing reports with respect to such delinquencies to us) processing and depositing collections and making periodic remittances;

| • |  | furnishing required periodic and current reports to us, the trustee, the Kansas commission and the rating agencies;

| • |  | making all filings with the Kansas commission and taking all other actions necessary to perfect our ownership interests in and the trustee’s first priority lien on the securitized utility tariff property and other portions of the collateral;

| • |  | selling, as our agent, defaulted or written off accounts in accordance with the servicer’s usual and customary practices;

| • |  | taking all necessary action in connection with true-up adjustments to the securitized utility tariff charges as described below; and

| • |  | performing such other duties as may be specified under the financing order to be performed by it.

Please read “ATMOS ENERGY’S FINANCING ORDER” in this prospectus. The servicer is required to notify us, the trustee and the rating agencies in writing of any laws, orders, directions or Kansas commission regulations promulgated after the execution of the servicing agreement that have a material adverse effect on the servicer’s ability to perform its duties under the servicing agreement. The servicer is also authorized to execute and deliver documents and to make filings and participate in proceedings on our behalf.

In the servicing agreement, the servicer will agree, among other things, that, in servicing the securitized utility tariff property, except where the failure to comply with any of the following would not materially adversely affect our or the trustee’s respective interests in the securitized utility tariff property:

| • |  | it will manage, service, administer, bill, charge, collect, receive and remit collections in respect of the securitized utility tariff property with reasonable care and in material compliance with applicable requirements of law, including all applicable Kansas commission regulations and guidelines, using the same degree of care and diligence that the servicer exercises with respect to similar assets for its own account and, if applicable, for others;

| • |  | it will follow standards, policies and procedures in performing its duties as servicer that are customary in the natural gas distribution industry;

| • |  | it will calculate the securitized utility tariff charges in compliance with the Securitization Act, the financing order and any applicable tariffs;

104

##### Table of Contents

| • |  | it will use all reasonable efforts consistent with its customary servicing procedures, to enforce, and maintain rights in respect of, the securitized utility tariff property and to impose, bill, charge, collect, receive and remit the securitized utility tariff charges;

| • |  | comply with all requirements of law, including all applicable Kansas commission regulations and guidelines, applicable to and binding on it relating to the securitized utility tariff property;

| • |  | file all reports with the Kansas commission required by the financing order;

| • |  | file and maintain the effectiveness of UCC financing statements in Kansas with respect to the property transferred under the sale agreement; and

| • |  | take such other action on behalf of us to ensure that the lien of the trustee on the collateral remains perfected and of first priority.

The servicer shall follow such customary and usual practices and procedures as it shall deem necessary or advisable in its servicing of all or any portion of the securitized utility tariff property, which, in the servicer’s judgment, may include the taking of legal action, at our expense but subject to the priority of payments set forth in the Indenture. The duties of the servicer set forth in the servicing agreement are qualified by any Kansas commission regulations or orders in effect at the time those duties are to be performed.

Servicer Obligation to Undertake Legal Action. The servicer is required, subject to applicable law, to negotiate for the retention of legal counsel and such other experts as may be needed to institute and maintain any action or proceeding on behalf of and in the name of the issuing entity necessary to compel performance by the Kansas commission or the State of Kansas or any other state agency of any of their obligations or duties under the Securitization Act or the financing order, and the servicer agrees to assist us and our legal counsel in taking such legal or administrative actions, including defending against or instituting and pursuing legal actions and appearing or testifying at hearings or similar proceedings, as may be reasonably necessary to attempt to block or overturn any attempts to cause a repeal of, modification of or supplement to the Securitization Act or the financing order, or the rights of holders of securitized utility tariff property by legislative enactment, constitutional amendment or other means that would be adverse to bondholders.

Remittances to the Trustee. The servicer will remit securitized utility tariff charges on each servicer business day to the trustee as soon as reasonably practicable after collection to the general subaccount of the collection account, but in no event later than two servicer business days following such collection date. The servicer shall also, promptly upon receipt, remit to the collection account any other proceeds of the securitized utility tariff collateral that it may receive from time to time.

Securitized Utility Tariff Charge Adjustment Process

Semi-Annual True-Ups. Among other things, the servicing agreement will require the servicer to file true-up adjustment requests at least semi-annually to correct any under-collections or over-collections during the preceding six months and to ensure the expected recovery of amounts sufficient to provide timely payment of principal and interest on the securitized utility tariff bonds and all other financing costs. For more information on the true-up process, please read “ATMOS ENERGY’S FINANCING ORDER—True-Ups.” These adjustment requests are to be based on actual collected securitized utility tariff charges and updated assumptions by the servicer as to projected future number of retail customers during the next period, expected delinquencies and write-offs and future payments and expenses relating to the securitized utility tariff property and the securitized utility tariff bonds. The servicer agrees to calculate these adjustments to:

| • |  | correct any under-collections or over-collections during the preceding six months; and

| • |  | ensure the expected recovery of amounts sufficient to timely provide all payments of the scheduled principal of and interest on the securitized utility tariff bonds and all other financing costs during the subsequent 12-month period (or, in the case of certain quarterly true-up adjustments, the period ending on the next securitized utility tariff bond payment date), consistent with the methodology described in the financing order.

105

##### Table of Contents

The servicer will agree to file adjustment requests on each calculation date for us as specified in the servicing agreement. In accordance with the financing order, the Kansas commission has 30 days from the servicer’s filing to approve the adjustments. Any adjustment to the allocation of securitized utility tariff charges will become effective on the proposed effective date, which cannot be less than 30 days of filing. Any adjustments to the securitized utility tariff charges will be made in future true-up adjustment filings.

Interim True-Ups. In addition to semi-annual true-up adjustments, true-up adjustments may be made by the servicer more frequently at any time during the term of the securitized utility tariff bonds to correct any under-collection to ensure timely payment of securitized utility tariff bonds as scheduled. In the event an interim true-up is necessary, the interim true-up adjustment should be filed by the 15th day of the current month for implementation in the first billing cycle of the following month. In no event would such interim true-up adjustments occur more frequently than every three months if quarterly securitized utility tariff bond payments are required or every six months if semi-annual bond payments are required; provided, however, that there shall be quarterly true-up adjustments for any securitized utility tariff bonds remaining outstanding during the year immediately preceding the scheduled final payment date of securitized utility tariff bonds.

Remittances to Collection Account

The servicer will remit securitized utility tariff charge collections on each servicer business day (the “daily remittance”) to the trustee for deposit to the general subaccount of the collection account as soon as reasonably practicable, but in no event later than two servicer business days following receipt of such securitized utility tariff charge collections. For a description of the allocation of the deposits, please read “DESCRIPTION OF THE SECURITIZED UTILITY TARIFF BONDS—How Funds in the Collection Account Will Be Allocated.” Until securitized utility tariff charge collections are remitted to the collection account, the servicer will not be required to segregate them from its general funds. Please read “RISK FACTORS—Risks associated with potential bankruptcy proceedings of the seller or the servicer” in this prospectus. Prior to, or concurrently with each such remittance to the general subaccount of the collection account, the servicer shall provide written notice to the trustee and, upon request, to us of such remittance. The servicer shall also, promptly upon receipt, remit to the collection account any other proceeds of the trust estate that it may receive from time to time. In the servicing agreement, the servicer will agree and acknowledge that it holds all securitized utility tariff charge payments or any other proceeds for the trust estate received by it for the benefit of the trustee and the securitized utility tariff bondholders and that all such amounts will be remitted by the servicer without any surcharge, fee, offset, charge or other deduction. The servicer shall not make any claim to reduce its obligation to remit all securitized utility tariff charge payments collected by it in accordance with the servicing agreement. Unless otherwise directed to do so by us, the servicer shall be responsible for selecting eligible investments in which the funds in the collection account shall be invested pursuant to the Indenture.

So long as the servicer faithfully makes all daily remittances of collected securitized utility tariff charges, as provided for in the servicing agreement, no actual or deemed investment earnings shall be payable in respect of such over-remittances or under-remittances.

Although the servicer will remit collected securitized utility tariff charges to the trustee, the servicer is not obligated to make any payments on the securitized utility tariff bonds. In the case of any shortfall, Atmos Energy will, first, allocate that shortfall ratably based on the amount owed to Atmos Energy or other parties (including those amounts associated with the securitized utility tariff bonds and similar securitization charges) and the amount owed for other fees and charges, other than late charges, and second, late fees and charges may be allocated to Atmos Energy. The portion owed in respect of securitized utility tariff charges may be further allocated ratably between us, as issuing entity of the securitized utility tariff bonds, and other affiliates of Atmos Energy who have issued securitized utility tariff bonds under the securitization provisions of the Securitization Act, as such bonds may be issued in the future.

Servicer Compensation

The servicer will be entitled to receive an aggregate annual servicing fee for all of the securitized utility tariff bonds outstanding in an amount equal to:

| • |  | 0.05% of the aggregate initial principal amount of the securitized utility tariff bonds plus reimbursable expenses for so long as Atmos Energy or an affiliate is the servicer; or

| • |  | If Atmos Energy or any of its affiliates is not the servicer, an amount agreed upon by the successor servicer and the trustee, provided that the annual servicing fee shall not exceed 0.60% of the aggregate initial principal amount of the securitized utility tariff bonds unless the Kansas commission has approved the appointment of the successor servicer or the Kansas commission does not act to approve or disapprove such appointment on or before the date which is 45 days after notice of the proposed appointment of the successor servicer is provided to the Kansas commission in the same manner substantially as provided for in the servicing agreement.

The servicing fee shall be paid semi-annually, with half of the servicing fee being paid on each payment date, except for the amount to be paid on the first payment date in which case the servicing fee then due will be calculated based on the number of days that the servicing agreement has been in effect. In addition, the servicer shall be entitled to be reimbursed by us for filing fees and fees and expenses for printing, attorneys, accountings, and other professional services incurred to meet our obligations under the basic documents. The servicing fee for the securitized utility tariff bonds will be subject to the priority of payments as described under “DESCRIPTION OF THE SECURITIZED UTILITY TARIFF BONDS—How Funds in the Collection Account Will Be Allocated” in this prospectus. The servicing fee for the securitized utility tariff bonds will be paid prior to the payment of or provision for any amounts in respect of interest on and principal of the securitized utility tariff bonds.

Atmos Energy’s Representations and Warranties as Servicer

| • |  | the servicer’s execution, delivery and performance of the terms of the servicing agreement have been duly authorized by all necessary action on the part of the servicer under its organizational or governing documents and laws;

| • |  | the servicing agreement constitutes a legal, valid and binding obligation of the servicer, enforceable against the servicer in accordance with its terms, subject to customary exceptions relating to bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer and certain equitable principles (regardless of whether considered in a proceeding in equity or at law);

| • |  | there are no proceedings or investigations pending or, to the servicer’s knowledge, threatened against the servicer before any court, federal or state regulatory body, administrative agency or other governmental instrumentality having jurisdiction over the servicer or its properties, seeking to prevent the issuance of the securitized utility tariff bonds or the consummation of the transactions contemplated by the servicing agreement or any of the other basic documents, or, if applicable, any supplement to the indenture or amendment to the sale agreement, seeking any determination or ruling that might materially and adversely affect the performance by the servicer of its obligations under, or the validity or enforceability against the servicer of, the servicing agreement or any of the other basic documents, or relating to the servicer and that might materially and adversely affect the treatment of the securitized utility tariff bonds for federal or state income, gross receipts or franchise tax purposes, no governmental approvals, authorizations, consents, orders or other actions or filings with any governmental authority are required for the servicer to execute, deliver and perform its obligations under the servicing agreement except those that have previously been obtained or made, those that are required to be made by the servicer in the future and those that the servicer may need to file in the future to continue the effectiveness of any financing statements; and

| • |  | each report and certificate delivered in connection with any filing made with the Kansas commission by the servicer on our behalf with respect to the securitized utility tariff charges or true-up adjustments will constitute a representation and warranty by the servicer that such report or certificate, as the case may be, is true and correct in all material respects, and to the extent that such report is based upon or contains assumptions, forecasts or other predictions of future events, the representation and warranty of the servicer with respect thereto will be limited to the representation and warranty that such assumptions, forecasts or other predictions of future events are reasonable based upon historical performance and the facts known to a responsible officer of the servicer on the date such report or certificate is delivered.

The servicer is not responsible for any decision, ruling, action or delay of the Kansas commission, except those caused by the servicer’s failure to file required applications in a timely and correct manner or other breach of its duties under the servicing agreement. The servicer also is not liable for the calculation of the securitized utility tariff charges and adjustments, including any inaccuracy in the assumptions made in the calculation, so long as the servicer has acted in good faith and has not acted in a grossly negligent manner.

The Servicer Will Indemnify Us, Other Entities and the Kansas Commission in Limited Circumstances

Under the servicing agreement, the servicer shall indemnify for, and defend and hold harmless, us, the trustee (for itself and for the benefit of the securitized utility tariff bondholders), the independent manager and each of their respective trustees, officers, directors, employees and agents for such persons from and against any and all reasonable costs, reasonable expenses, obligations, payments, claims, losses, damages and liabilities of any kind whatsoever imposed on, incurred by or asserted against any such person as a result of:

| • |  | the servicer’s willful misconduct, bad faith or gross negligence in the performance of, or reckless disregard of, its duties or observance of its covenants under the servicing agreement;

| • |  | the servicer’s material breach of any of its representations or warranties that results in a servicer default under the servicing agreement;

108

##### Table of Contents

| • |  | litigation and related expenses relating to the servicer’s status and obligations as servicer (other than any proceedings the servicer is required to institute under the servicing agreement); and

| • |  | the costs and expenses (including legal costs and expenses) of enforcing the indemnification obligations of the servicer.

The servicer will not be liable to any such party, however, for any reasonable costs, reasonable expenses, obligations, payments, claims, losses, damages and liabilities of any kind whatsoever, resulting from the willful misconduct, bad faith or gross negligence of the party seeking indemnification.

The servicer will also credit its retail customers to the extent there are higher securitized utility tariff charges, including higher servicing fees payable to a successor servicer, because of the servicer’s negligence, recklessness, willful misconduct or termination of the servicing agreement for cause, provided that any such credit shall not impact the securitized utility tariff charges or the securitized utility tariff property.

Limitation on Liability of Servicer and Others

Except as expressly provided in the servicing agreement, neither the servicer, nor any of its directors, officers, employees and agents will be liable to us or any other person for any action taken or for refraining from taking any action pursuant to the servicing agreement or for good faith errors in judgment. However, the servicer and any such person shall not be protected against any liability that would otherwise be imposed by reason of gross negligence, recklessness or willful misconduct in the performance of duties or by reason of reckless disregard of obligations and duties under the servicing agreement. The servicer and any of its directors, officers, employees or agents may rely in good faith on the advice of counsel or on any document, prima facie properly executed and submitted by any person respecting any matters under the servicing agreement. Except as described above in this paragraph, the servicer shall not have any liability whatsoever as a result of any person or entity, including the holders, not receiving any payment, amount or return anticipated or expected or in respect of any securitized utility tariff bonds generally. In addition, the servicing agreement will provide that the servicer is under no obligation to appear in, prosecute, or defend any legal action, except as provided in the servicing agreement.

The Servicer Will Provide Statements to Us, the Kansas Commission and the Trustee

Not later than five business days prior to each payment date or special payment date, the servicer will deliver a written report to us, the Kansas commission, the trustee and the rating agencies, which shall include all of the following information, to the extent applicable and including any other information as so specified in the series supplement, as to the securitized utility tariff bonds with respect to such payment date or special payment date or the period since the previous payment date, as appliable:

| • |  | the securitized utility tariff bond balance and the projected securitized utility tariff bond balance as of the immediately preceding payment date;

| • |  | the amount on deposit in the capital subaccount and the excess funds subaccount and the amount required to be on deposit in the capital subaccount as of the immediately preceding payment date;

| • |  | the amount of the payment to securitized utility tariff bondholders allocable to principal, if any;

| • |  | the amount of the payment to securitized utility tariff bondholders allocable to interest;

| • |  | the aggregate outstanding amount of the securitized utility tariff bonds, before and after giving effect to any payments allocated to principal reported as above;

| • |  | the difference, if any, between the aggregate outstanding amount provided above and the outstanding amount specified in the expected amortization schedule;

| • |  | any other transfers and payments to be made on such payment date or special payment date, including amounts paid to the trustee or to the servicer; and

| • |  | the servicer’s projection of the amount on deposit in the excess funds subaccount for the payment date immediately preceding the next succeeding adjustment date.

The Servicer Will Provide Assessments Concerning Compliance with the Servicing Agreement

The servicing agreement will provide that the servicer will furnish annually to us, the Kansas commission, the trustee and the rating agencies, on or before December 31 of each year, commencing in 2023, to and including the December 31 succeeding the final maturity date of the securitized utility tariff bonds, certificates by an officer of the servicer (a) containing and certifying statements of compliance required by Item 1123 of Regulation AB of the SEC and (b) containing and certifying its statements and assessment of compliance with specified servicing criteria as required by Item 1122(a) of Regulation AB of the SEC, as then in effect, during the preceding 12 months ended December 31 (or preceding period since the closing date of the issuance of the securitized utility tariff bonds in the case of the first statement), including a statement that to the best of such officer’s knowledge, the servicer has fulfilled its obligations under the servicing agreement for the preceding calendar year, or the relevant portion thereof, or, if there has been a default in the fulfillment of any relevant obligation, stating that there has been a default and describing each default. The servicer has agreed to give us, the Kansas commission, each rating agency and the trustee written notice of any servicer default under the servicing agreement.

The servicing agreement will provide that a firm of independent certified public accountants will furnish to us, the Kansas commission, the trustee and the rating agencies, on or before the earlier of (i) December 31 of each year, beginning December 31, 2023, to and including the December 31 succeeding the retirement of all securitized utility tariff bonds or (ii) with respect to each calendar year during which the sponsor’s annual report on Form 10-K is required to be filed in accordance with the Exchange Act and the rules and regulations thereunder, the date on which such annual report on Form 10-K is required to be filed in accordance with the Exchange Act and the rules and regulations thereunder, a report addressed to the servicer regarding the servicer’s assessment of compliance with the servicing criteria set forth in Item 1122(d) of Regulation AB during the immediately preceding twelve months ended December 31 (or, in the case of the first annual accountant’s report to be delivered on or before December 31, 2023, the period of time from the issuance of the securitized utility tariff bonds until December 31, 2023), in accordance with paragraph (b) of Rule 13a-18 and Rule 15d-18 of the Exchange Act and Item 1122 of Regulation AB, identifying the results of such procedures and including any exceptions noted. This report, which is referred to in this prospectus as the “annual accountant’s report,” will state that the accounting firm has performed certain procedures, agreed between the servicer and such accountants, in connection with the servicer’s compliance with its obligations under the sale agreement during the preceding calendar year, identifying the results of the procedures and including any exceptions to the procedures relating to the servicing of the securitized utility tariff property.

Matters Regarding Atmos Energy as the Servicer

Atmos Energy shall not resign from its obligation and duties as servicer under the servicing agreement except upon a determination that its performance of its duties shall no longer be permissible under the applicable requirements of law. Notice of such determination permitting such resignation will be communicated to us, the Kansas commission, the trustee and each rating agency at the earliest practicable time, and any such determination shall be evidenced by an opinion of counsel to such effect. No such resignation shall become effective until a successor servicer has been approved by the Kansas commission and has assumed the servicing obligations and duties of the servicer in accordance with the servicing agreement.

The obligations to continue to provide service and to collect and account for securitized utility tariff charges will be binding upon the servicer, any successor and any other entity that provides natural gas distribution services to a person that is a Kansas retail customer of Atmos Energy or any successor so long as the securitized utility tariff charges have not been fully collected and remitted. Under the servicing agreement, any person:

| • |  | into which the servicer may be merged, converted or consolidated;

| • |  | that may result from any merger, conversion or consolidation to which the servicer shall be a party; or

| • |  | that may succeed to the properties and assets of the servicer substantially as a whole;

110

##### Table of Contents

shall be the successor to the servicer under the servicing agreement without further act on the part of the parties under that agreement, provided however, that certain conditions are met and that such person executed an agreement of assumption to perform all of the obligations of the servicer. These conditions include the following:

| • |  | immediately after giving effect to such transaction referred to above, no representation or warranty made by the servicer in the servicing agreement shall have been breached and no servicer default and no event that, after notice or lapse of time, or both, would become a servicer default, will have occurred and be continuing;

| • |  | an officers’ certificate and opinions of counsel from external counsel will have been delivered to us, the Kansas commission and the trustee stating that the transaction referred to above and such agreement of assumption referred to above complies with the servicing agreement and all conditions to transfer under the servicing agreement;

| • |  | the servicer shall have delivered to us, the Kansas commission, the trustee and the ratings agencies an opinion of counsel from external counsel of the servicer either stating that (i) in the opinion of such counsel, all filings to be made by the servicer, including filings with the Kansas commission pursuant to the Securitization Act and the UCC, have been executed and filed and are in full force and effect that are necessary to fully preserve, perfect and maintain the our priority interests and the liens of the trustee in the securitized utility tariff property and reciting the details of such filings or (ii) in the opinion of such counsel, no such action shall be necessary to preserve and protect such interests;

| • |  | the servicer has delivered to us, the Kansas commission, the trustee and the rating agencies a no material adverse tax change opinion of independent tax counsel regarding such transfer; and

| • |  | prior written notice will have been received by the rating agencies.

The servicing agreement will permit the servicer to appoint any person to perform any or all of its obligations under the servicing agreement. However, unless the appointed person is an affiliate of Atmos Energy, the appointment must satisfy the rating agency condition. In all cases where an agent is appointed, the servicer will remain obligated and liable under the servicing agreement.

Events Constituting a Default by the Servicer

Servicer defaults under the servicing agreement will include, among other things:

| • |  | any failure by the servicer to remit to the collection account, on our behalf, any remittance required to be remitted pursuant to the servicing agreement that continues unremedied for five servicer business days after written notice of such failure is received by the servicer from us or from the trustee or after actual knowledge of such failure by a responsible officer of the servicer;

| • |  | any failure in any material respect by the servicer to duly observe or perform its obligations to make securitized utility tariff charge adjustment filings in the time and manner set forth in the servicing agreement, which failure continues unremedied for a period of five business days;

| • |  | any failure on the part of the servicer or, so long as the servicer is Atmos Energy or an affiliate thereof, any failure on the part of Atmos Energy, as the case may be, duly to observe or to perform, in any material respect, any covenant or agreement of the servicer set forth in the servicing agreement or any other basic document to which it is a party, which failure materially and adversely affects the holders and continues unremedied for 60 days after written notice of this failure has been given to the servicer by us, the Kansas commission or the trustee or after this failure is actually known by a responsible officer of the servicer, as the case may be;

| • |  | any representation or warranty made by the servicer in the servicing agreement or any other basic document proves to have been incorrect in a material respect when made, which has a material adverse effect on holders and which continues unremedied for 60 days after written notice of this failure,

111

##### Table of Contents

requiring the same to be remedied, has been given to the servicer by us or the trustee or such failure is discovered by a responsible officer of the servicer, as the case may be; or

| • |  | certain events of bankruptcy, insolvency or liquidation of the servicer.

The Trustee’s Rights if the Servicer Defaults

In the event a servicer default under the servicing agreement remains unremedied, the trustee acting under the indenture may, or upon the instruction of (i) the holders of not less than a majority of the outstanding principal amount of the securitized utility tariff bonds or (ii) the Kansas commission, shall, by written notice to the servicer, terminate all the rights and obligations of the servicer under the servicing agreement, other than the servicer’s indemnification obligation and obligation to continue performing its functions as servicer until a successor servicer is appointed. Under the servicing agreement, the servicer’s indemnity obligations to us, the trustee and the independent manager will survive its replacement as servicer. After the termination of the responsibilities and rights of the predecessor servicer as described above, the trustee will appoint a successor servicer who will succeed to all the rights and duties of the servicer under the servicing agreement and will be entitled to similar compensation arrangements. The predecessor servicer shall, on an ongoing basis, cooperate with us and successor servicer and provide whatever information is, and take whatever actions are, reasonably necessary to assist the successor servicer in performing its obligations hereunder.

In addition, when a servicer defaults, the bondholders of the securitized utility tariff bonds (subject to the provisions of the Indenture) and the trustee as beneficiary of any lien permitted by the Securitization Act will be entitled to apply to the Kansas commission or a court of appropriate jurisdiction for an order of sequestration and payment of revenues arising from the applicable securitized utility tariff property. Upon a servicer default based upon the commencement of a case by or against the servicer under the bankruptcy or insolvency laws, the trustee may be prevented from effecting a transfer of servicing. Please read “RISK FACTORS—Risks associated with potential bankruptcy proceedings of the seller or the servicer” and “HOW A BANKRUPTCY MAY AFFECT YOUR INVESTMENT” in this prospectus. The trustee may appoint, at the written direction of the securitized utility tariff bondholders evidencing a majority in principal amount of the then outstanding securitized utility tariff bonds, or petition a court of competent jurisdiction for the appointment of, a successor servicer which satisfies criteria specified by the rating agencies rating the securitized utility tariff bonds.

Waiver of Past Defaults

The trustee, with the written consent of the securitized utility tariff bondholders evidencing a majority in principal amount of the then outstanding securitized utility tariff bonds, may waive in writing any default by the servicer in the performance of its obligations under the servicing agreement and its consequences, except a default in making any required deposits to the collection account in accordance with the servicing agreement. The servicing agreement provides that no waiver will impair the securitized utility tariff bondholders’ rights relating to subsequent defaults.

The Replacement of Atmos Energy as Servicer with a Successor Servicer

Upon the event of default by the servicer under the servicing agreement relating to the servicer’s performance of its servicing functions with respect to the securitized utility tariff charges, Atmos Energy may be replaced as the servicer under the terms of the servicing agreement with our prior written consent (which we shall not unreasonably withhold). The successor servicer shall not begin providing service until (i) the Kansas commission approves the appointment of such successor servicer or (ii) the Kansas commission does not act to either approve or disapprove the appointment of the successor servicer within 60 days after notice of appointment of the successor servicer is provided to the Kansas commission. Additionally, no entity may replace Atmos Energy as the servicer if the replacement would cause any of the then-current credit ratings of the securitized utility tariff bonds to be suspended, withdrawn, or downgraded. To the extent a higher servicing fee is caused by

112

##### Table of Contents

the appointment of a successor servicer not affiliated with Atmos Energy due to the negligence, recklessness, willful misconduct or termination of the servicing agreement for cause of Atmos Energy or an affiliate of Atmos Energy, the servicing agreement provides that Atmos Energy shall bear the increased portion, and not its customers.

The Obligations of a Successor Servicer

Pursuant to the provisions of the servicing agreement, if for any reason a third party assumes or succeeds to the role of the servicer under the servicing agreement, the servicing agreement will require the predecessor servicer to cooperate with us, the trustee and the successor servicer in terminating the predecessor servicer’s rights and responsibilities under the servicing agreement, including the transfer to the successor servicer of all documentation pertaining to the securitized utility tariff property and all cash amounts then held by the predecessor servicer for remittance or subsequently acquired by the predecessor servicer. The servicing agreement will provide that the predecessor servicer will be liable for all reasonable costs and expenses incurred in transferring servicing responsibilities to the successor servicer in the event the successor servicer is appointed as a result of a servicer default. In all other cases, those costs and expenses will be paid by the party incurring them. A successor servicer may resign only if it is prohibited from serving as servicer pursuant to the servicing agreement by applicable law. The predecessor servicer is obligated on an ongoing basis to cooperate with us and the successor servicer and to provide whatever information is, and take whatever commercially reasonable actions are, reasonably necessary to assist the successor servicer in performing its obligations under the servicing agreement.

Amendment

The servicing agreement may be amended in writing by the parties thereto, provided that the rating agency condition has been satisfied, the trustee has consented and, with respect to amendments that would increase ongoing financing costs, the prior approval of the Kansas commission. An amendment that requires the prior approval of the Kansas commission is subject to the objection of the Kansas commission within a 30-day period and subject to the conditions set forth in the servicing agreement. We will notify the rating agencies promptly after the execution of any such amendment.

HOW A BANKRUPTCY MAY AFFECT YOUR INVESTMENT

Challenge to True Sale Treatment. Atmos Energy will represent and warrant that the transfer of the securitized utility tariff property in accordance with the sale agreement constitutes a true and valid sale and assignment of the securitized utility tariff property by Atmos Energy to us. It will be a condition of closing for the sale of the securitized utility tariff property pursuant to the sale agreement that Atmos Energy will take the appropriate actions under the Securitization Act, including filing a notice of transfer of an interest in the securitized utility tariff property, to perfect this sale. The Securitization Act provides that a transfer of securitized utility tariff property by a utility to an assignee which the parties have in the governing documentation expressly stated to be a sale or other absolute transfer, in a transaction approved in a financing order, shall be treated as an absolute transfer of all the transferor’s right, title and interest, as a “true sale” under applicable creditors’ rights principles, and not as a pledge or other financing, of the relevant securitized utility tariff property. The sale agreement provides that we and Atmos Energy will treat such a transaction as a sale under applicable law. However, we expect that the securitized utility tariff bonds will be reflected as debt on Atmos Energy’s consolidated financial statements. In addition, we anticipate that the securitized utility tariff bonds will be treated as debt of Atmos Energy for federal income tax purposes. See “THE SECURITIZATION ACT—Atmos Energy May Securitize Qualified Extraordinary Costs and Related Upfront and Ongoing Financing Costs” and “MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES.” In the event of a bankruptcy of a party to the sale agreement, if a party in interest in the bankruptcy were to take the position that the transfer of the securitized utility tariff property to us pursuant to that sale agreement was a financing transaction and not a true sale under applicable creditors’ rights principles, there can be no assurance that a court would not adopt this position. Even if a court did not ultimately recharacterize the transaction as a financing transaction, the mere commencement of a bankruptcy of Atmos Energy and the attendant possible uncertainty surrounding the treatment of the transaction could result in delays in payments on the securitized utility tariff bonds.

In that regard, we note that the bankruptcy court in In re: LTV Steel Company, Inc., et al., 274 B.R. 278 (Bankr. N. D. Oh. 2001) issued an interim order that observed that a debtor, LTV Steel Company, which had previously entered into securitization arrangements with respect both to its inventory and its accounts receivable may have “at least some equitable interest in the inventory and receivables, and that this interest is property of the Debtor’s estate... sufficient to support the entry of” an interim order permitting the debtor to use proceeds of the property sold in the securitization. 274 B.R. at 285. The court based its decision in large part on its view of the equities of the case.

LTV and the securitization investors subsequently settled their dispute over the terms of the interim order and the bankruptcy court entered a final order in which the parties admitted and the court found that the pre-petition transactions constituted “true sales.” The court did not otherwise overrule its earlier ruling. The LTV memorandum opinion serves as an example of the pervasive equity powers of bankruptcy courts and the importance that such courts may ascribe to the goal of reorganization, particularly where the assets sold are integral to the ongoing operation of the debtor’s business.

Even if no creditor challenges the sale of securitized utility tariff property to us as a true sale, a bankruptcy filing by Atmos Energy could trigger a bankruptcy filing by the issuing entity with similar negative consequences for bondholders. In a recent bankruptcy case, In re General Growth Properties, Inc., 406 B.R. 171 (Bankr. S.D.N.Y. 2009), General Growth Properties, Inc. filed for bankruptcy protection, along with many of its direct and indirect subsidiaries. Those subsidiaries included many entities that had been organized as special purpose vehicles. The bankruptcy court upheld the validity of the filings of these special purpose subsidiaries as bankruptcy debtors and allowed the subsidiaries, over the objections of their own creditors, to use the creditors’ cash collateral to fund loans to the parent debtor, General Growth Properties, Inc., for its general corporate purposes. The creditors received court-determined adequate protection in the form of current interest payments and replacement liens to mitigate any diminution in value resulting from the use of the cash collateral, but the opinion serves as a reminder that bankruptcy courts may subordinate legal rights of creditors to the interests of facilitation of the reorganization of a debtor.

114

##### Table of Contents

We and Atmos Energy have attempted to mitigate the impact of a possible recharacterization of a sale of securitized utility tariff property as a financing transaction under applicable creditors’ rights principles. This does not, however, eliminate the risk of payment delays or losses and other adverse effects caused by an Atmos Energy bankruptcy. Further, if, for any reason, a securitized utility tariff property notice is not filed under the Securitization Act or we fail to otherwise perfect our interest in the securitized utility tariff property, and the transfer is thereafter deemed not to constitute a true sale, we would be an unsecured creditor of Atmos Energy.

The Securitization Act provides that the creation, granting, perfection and enforcement of liens and security interests in the securitized utility tariff property are governed by the Securitization Act and not by the UCC (except, as to perfection, with respect to the filing of financing statements in places specified in the UCC and to conformity of the form of financing statements with provisions of the UCC). Under the Securitization Act, a valid and enforceable consensual security interest in the securitized utility tariff property may be created only by the execution and delivery of a security agreement with a securitized utility tariff bondholder or a trustee or agent for the holder that refers to the specific financing order that created the securitized utility tariff property. The Securitization Act provides that the security interest attaches automatically from the time value is received for the securitized utility tariff bonds. The Securitization Act provides that upon perfection through the filing of notice with the Kansas Secretary of State pursuant to rules established by the Secretary of State of Kansas, the security interest shall be a continuously perfected lien and security interest in the securitized utility tariff property, with priority in the order of filing and take precedence over any subsequent judicial or other lien creditor. The Securitization Act provides that the security interest will be perfected as of the date of filing.

None of this, however, eliminates the risk of payment delays, losses and other adverse effects caused by an Atmos Energy bankruptcy. Further, if, for any reason, a securitized utility tariff property notice is not filed under the Securitization Act or we fail to otherwise perfect our interest in the securitized utility tariff property sold pursuant to the sale agreement, and the transfer is thereafter deemed not to constitute a true sale, we would be an unsecured creditor of Atmos Energy.

Consolidation of Atmos Energy and Us. If Atmos were to become a debtor in a bankruptcy case, a party in interest might attempt to substantively consolidate the assets and liabilities of Atmos Energy and us. We and Atmos Energy have taken steps to attempt to minimize this risk. Please read “ATMOS ENERGY KANSAS SECURITIZATION I, LLC, THE ISSUING ENTITY” in this prospectus. However, no assurance can be given that if Atmos Energy were to become a debtor in a bankruptcy case, a court would not order that our assets and liabilities be substantively consolidated with those of Atmos Energy. Substantive consolidation would result in payment of the claims of the beneficial owners of the securitized utility tariff bonds to be subject to substantial delay and potentially to adjustment in timing and/or amount.

Status of Securitized Utility Tariff Property as Current Property. Atmos Energy will represent in the sale agreement, and the Securitization Act provides, that the securitized utility tariff property sold pursuant to the sale agreement constitutes a present contract right. Nevertheless, no assurance can be given that, in the event of a bankruptcy of Atmos Energy, a court would not rule that the securitized utility tariff property comes into existence only as Atmos Energy’s customers use natural gas.

If a court were to accept the argument that the securitized utility tariff property comes into existence only as Atmos Energy’s customers use natural gas, no assurance can be given that a security interest in favor of the bondholders of the securitized utility tariff bonds would attach to the securitized utility tariff charges in respect of natural gas consumed after the commencement of the bankruptcy case or that the securitized utility tariff property has been sold to us. If it were determined that the securitized utility tariff property had not been sold to us, and the security interest in favor of the securitized utility tariff bondholders did not attach to the securitized utility tariff charges in respect of natural gas consumed after the commencement of the bankruptcy case, then we would have an unsecured claim against Atmos Energy. If so, there would be delays and/or reductions in payments on the securitized utility tariff bonds. Whether or not a court determined that securitized utility tariff property had been sold to us pursuant to the sale agreement, no assurances can be given that a court would not rule that any

115

##### Table of Contents

securitized utility tariff charges relating to natural gas consumed after the commencement of the bankruptcy could not be transferred to us or the trustee.

In addition, in the event of a bankruptcy of Atmos Energy, a party in interest in the bankruptcy could assert that we should pay, or that we should be charged for, a portion of Atmos Energy’s costs associated with the natural gas, consumption of which gave rise to the Securitized Utility Tariff Charge receipts used to make payments on the securitized utility tariff bonds.

Regardless of whether Atmos Energy is the debtor in a bankruptcy case, if a court were to accept the argument that the securitized utility tariff property sold pursuant to the sale agreement comes into existence only as customers use natural gas, a tax or government lien or other nonconsensual lien on property of Atmos Energy arising before the securitized utility tariff property came into existence could have priority over our interest in the securitized utility tariff property. Adjustments to the securitized utility tariff charges may be available to mitigate this exposure, although there may be delays in implementing these adjustments.

Estimation of Claims; Challenges to Indemnity Claims. If Atmos Energy were to become a debtor in a bankruptcy case, claims, including indemnity claims, by us or the trustee against Atmos Energy as seller under the sale agreement and the other documents executed in connection therewith could be unsecured claims and would be subject to being discharged in the bankruptcy case. In addition, a party in interest in the bankruptcy may request that the bankruptcy court estimate any contingent claims that we or the trustee have against Atmos Energy. That party may then take the position that these claims should be estimated at zero or at a low amount because the contingency giving rise to these claims is unlikely to occur. If a court were to hold that the indemnity provisions were unenforceable, we would be left with a claim for actual damages against Atmos Energy based on breach of contract principles. The actual amount of these damages would be subject to estimation and/or calculation by the court.

No assurances can be given as to the result of any of the above-described actions or claims. Furthermore, no assurance can be given as to what percentage of their claims, if any, unsecured creditors would receive in any bankruptcy proceeding involving Atmos Energy.

Enforcement of Rights By the Trustee. Upon an event of default under the Indenture, the Securitization Act permits the trustee to enforce the security interest in the securitized utility tariff property sold pursuant to the sale agreement in accordance with the terms of the Indenture. In this capacity, the trustee is permitted to request the Kansas commission or the 10th Judicial District, District Court of Johnson County, Kansas to order the sequestration and payment to holders of the securitized utility tariff bonds of all revenues arising from the securitized utility tariff charges. There can be no assurance, however, that the Kansas commission or a court would issue such an order, including if seller is a debtor in bankruptcy in light of the automatic stay provisions of Section 362 of the United States Bankruptcy Code. In that event, the trustee may under the Indenture seek an order from the bankruptcy court lifting the automatic stay with respect to this action by the Kansas commission or a court and an order requiring an accounting and segregation of the revenues arising from the securitized utility tariff property sold pursuant to the sale agreement. There can be no assurance that a court would grant either order.

Bankruptcy of the Servicer. The servicer is entitled to commingle the securitized utility tariff charges that it receives with its own funds until each date on which the servicer is required to remit funds to the trustee as specified in the servicing agreement. The Securitization Act provides that the relative priority of a lien created under the Securitization Act is not defeated or adversely affected by the commingling of securitized utility tariff charges arising with respect to the securitized utility tariff property with funds of the natural gas utility. In the event of a bankruptcy of the servicer, a party in interest in the bankruptcy might assert, and a court might rule, that the securitized utility tariff charges commingled by the servicer with its own funds and held by the servicer, prior to and as of the date of bankruptcy were property of the servicer as of that date, and are therefore property of the servicer’s bankruptcy estate, rather than our property. If the court so rules, then the court could rule that

116

##### Table of Contents

the trustee has only a general unsecured claim against the servicer for the amount of commingled securitized utility tariff charges held as of that date and could not recover the commingled securitized utility tariff charges held as of the date of the bankruptcy.

However the court rules on the ownership of the commingled securitized utility tariff charges, the automatic stay arising upon the bankruptcy of the servicer could delay the trustee from receiving the commingled securitized utility tariff charges held by the servicer as of the date of the bankruptcy until the court grants relief from the stay. A court ruling on any request for relief from the stay could be delayed pending the court’s resolution of whether the commingled securitized utility tariff charges are our property or are property of the servicer, including resolution of any tracing of proceeds issues.

The servicing agreement will provide that the trustee, as our assignee, together with the other persons specified therein, may vote to appoint a successor servicer that satisfies the rating agency condition. The servicing agreement will also provide that the trustee, together with the other persons specified therein, may petition the Kansas commission or a court of competent jurisdiction to appoint a successor servicer that meets this criterion. However, the automatic stay in effect during a servicer bankruptcy might delay or prevent a successor servicer’s replacement of the servicer. Even if a successor servicer may be appointed and may replace the servicer, a successor may be difficult to obtain and may not be capable of performing all of the duties that Atmos Energy as servicer was capable of performing. Furthermore, should the servicer enter into bankruptcy, it may be permitted to stop acting as the servicer.

Bankruptcy of Atmos Energy. Atmos Energy is not required to segregate the securitized utility tariff charges it collects from its general funds. The Securitization Act provides that our rights to the securitized utility tariff property are not affected by the commingling of these funds with other funds. In a bankruptcy of Atmos Energy, however, a bankruptcy court might rule that federal bankruptcy law takes precedence over the Securitization Act and does not recognize our right to receive the collected securitized utility tariff charges that are commingled with other funds of Atmos Energy prior to or as of the date of bankruptcy, including securitized utility tariff charges associated with another series of securitized utility tariff bonds. If so, the collected securitized utility tariff charges held by Atmos as of the date of bankruptcy would not be available to us to pay amounts owed on the securitized utility tariff bonds. In this case, we would have only a general unsecured claim against Atmos Energy for those amounts.

In addition, the bankruptcy of Atmos Energy may cause a delay in or prohibition of enforcement of various rights against Atmos, including rights to require payments by Atmos Energy, rights to require Atmos Energy to comply with financial provisions of the Securitization Act or other state laws, rights to terminate contracts with Atmos Energy and rights that are conditioned on the bankruptcy, insolvency or financial condition of Atmos Energy. Such a bankruptcy also may give rise to potential preference claims related to certain payments by Atmos Energy.

Other risks relating to bankruptcy may be found in “RISK FACTORS—Risks associated with potential bankruptcy proceedings of the seller or the servicer.”

USE OF PROCEEDS

Upon the issuance of the securitized utility tariff bonds, we will use the net proceeds from the sale of the securitized utility tariff bonds to pay to Atmos Energy the purchase price of Atmos Energy’s rights under the financing order, which are the securitized utility tariff property.

Atmos Energy will use the net proceeds from the sale of the securitized utility tariff property (after payment of upfront financing costs) to recover, finance or refinance a portion of the qualified extraordinary costs of Atmos Energy as approved by the Kansas commission. Atmos Energy’s qualified extraordinary costs are currently estimated to be approximately $125 million (including financing costs) and are related to Winter Storm Uri.

PLAN OF DISTRIBUTION

Subject to the terms and conditions in the underwriting agreement among us, Atmos Energy and J.P. Morgan Securities LLC, as sole underwriter, we have agreed to sell to the underwriter, and the underwriter has agreed to purchase, the principal amount of the securitized utility tariff bonds listed opposite its name below:

Underwriter |  | Tranche A |
J.P. Morgan Securities LLC |  | $ |  |

Under the underwriting agreement, the underwriter will take and pay for all of the securitized utility tariff bonds we offer, if any is taken.

The Underwriter’s Sales Price for the Securitized Utility Tariff Bonds

The securitized utility tariff bonds sold by the underwriter to the public will be initially offered at the prices to the public set forth on the cover of this prospectus. The underwriter proposes initially to offer the securitized utility tariff bonds to dealers at such prices, less a selling concession not to exceed the percentage listed below. The underwriter may allow, and dealers may reallow, a discount not to exceed the percentage listed below.

|  | Selling Concession |  |  | Reallowance Discount |
Tranche A |  |  |  | % |  |  |  | %

After the initial public offering, the public offering price, selling concession and reallowance discount may change.

No Assurance as to Resale Price or Resale Liquidity for the Securitized Utility Tariff Bonds

The securitized utility tariff bonds are a new issue of securities with no established trading market. They will not be listed on any securities exchange. The underwriter has advised us that it intends to make a market in the securitized utility tariff bonds, but it is not obligated to do so and may discontinue market making at any time without notice. We cannot assure you that a liquid trading market will develop for the securitized utility tariff bonds.

Various Types of Underwriter Transactions that May Affect the Price of the Securitized Utility Tariff Bonds

The underwriter may engage in overallotment transactions, stabilizing transactions, syndicate covering transactions and penalty bids with respect to the securitized utility tariff bonds in accordance with Regulation M under the Exchange Act. Overallotment transactions involve syndicate sales in excess of the offering size, which create a syndicate short position. Stabilizing transactions are bids to purchase the securitized utility tariff bonds, which are permitted, so long as the stabilizing bids do not exceed a specific maximum price. Syndicate covering transactions involve purchases of the securitized utility tariff bonds in the open market after the distribution has been completed in order to cover syndicate short positions. Penalty bids permit the underwriter to reclaim a selling concession from a syndicate member when the securitized utility tariff bonds originally sold by the syndicate member are purchased in a syndicate covering transaction. These overallotment transactions, stabilizing transactions, syndicate covering transactions and penalty bids may cause the prices of the securitized utility tariff bonds to be higher than they would otherwise be. Neither we, Atmos Energy, the trustee, our managers nor the underwriter represents that the underwriter will engage in any of these transactions or that these transactions, if commenced, will not be discontinued without notice at any time.

The underwriter and its affiliates have in the past provided, and may in the future from time to time provide, investment banking and general financing and banking services to Atmos Energy and its affiliates for which they have in the past received, and in the future may receive, customary fees. In addition, the underwriter may from time to time take positions in the securitized utility tariff bonds.

We estimate that the registrants’ total expenses of the offering will be approximately $3.0 million.

We and Atmos Energy have agreed to indemnify the underwriter against some liabilities, including liabilities under the Securities Act of 1933, or to contribute to payments the underwriter may be required to make in respect of those liabilities. Pursuant to the underwriting agreement, we and Atmos Energy will reimburse the underwriter for its reasonable out-of-pocket expenses in an aggregate amount not exceeding $200,000.

The underwriter is offering the securitized utility tariff bonds, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters, including the validity of the securitized utility tariff bonds and other conditions contained in the underwriting agreement, such as receipt of ratings confirmations, officers’ certificates and legal opinions. The underwriter reserves the right to withdraw, cancel or modify offers to the public and to reject offers in whole or in part.

We expect to deliver the securitized utility tariff bonds against payment for the securitized utility tariff bonds on or about the date specified in the last paragraph of the cover page of this prospectus, which will be the business day following the date of pricing of the securitized utility tariff bonds. Since trades in the secondary market generally settle in two business days, purchasers who wish to trade securitized utility tariff bonds on the date of pricing or the succeeding business days will be required, by virtue of the fact that the securitized utility tariff bonds initially will settle in T + , to specify alternative settlement arrangements to prevent a failed settlement.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES

General

The following is a general discussion of the anticipated material U.S. federal income tax consequences of the purchase, ownership and disposition of the securitized utility tariff bonds. Except as specifically provided below with respect to non-U.S. holders (as defined below), this discussion does not address the tax consequences to persons other than initial purchasers who are U.S. holders (as defined below) that acquire securitized utility tariff bonds at original issue for cash equal to the issue price of those bonds and hold their securitized utility tariff bonds as capital assets within the meaning of Section 1221 of the Internal Revenue Code, and it does not address all of the tax consequences relevant to investors that are subject to special treatment under the United States federal income tax laws (e.g., life insurance companies, tax-exempt organizations, financial institutions, dealers in securities, S corporations, taxpayers subject to the alternative minimum tax provisions of the Internal Revenue Code, broker-dealers, persons who hold the securitized utility tariff bonds as part of a hedge, straddle, “synthetic security” or other integrated investment, risk reduction or constructive sale transaction and persons required to accelerate the recognition of any item of gross income with respect to the notes as a result of such income being recognized on an “applicable financial statement” (within the meaning of Section 451(b) of the Code)). This discussion also does not address U.S. federal taxes other than income tax or the consequences to holders of the securitized utility tariff bonds under state, local or foreign tax laws. Please read “MATERIAL KANSAS INCOME TAX CONSEQUENCES” in this prospectus. However, by acquiring a securitized utility tariff bond, a holder agrees to treat the securitized utility tariff bond as a debt of Atmos Energy to the extent consistent with applicable state, local and other tax law unless otherwise required by appropriate taxing authorities.

This summary is based on current provisions of the Internal Revenue Code, the Treasury Regulations promulgated and proposed thereunder, judicial decisions and published administrative rulings and pronouncements of the IRS and interpretations thereof. All of these authorities and interpretations are subject to change, and any change may apply retroactively and affect the accuracy of the opinions, statements and conclusions set forth in this discussion. We have not, and do not intend to seek, any ruling from the IRS with respect to the statements made and conclusions reached in this summary.

U.S. Holder and Non-U.S. Holder Defined

A “U.S. holder” means a beneficial owner of a securitized utility tariff bond that, for U.S. federal income tax purposes, is (i) a citizen or individual resident of the United States, (ii) a corporation (including an entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia, (iii) an estate, the income of which is includible in gross income for U.S. federal income tax purposes regardless of its source, or (iv) a trust, if (A) a court in the United States is able to exercise primary supervision over the administration of the trust and one or more United States persons have the authority to control all substantial decisions of the trust, or (B) it has a valid election in place to be treated as a United States person. A “non-U.S. holder” means a beneficial owner of a securitized utility tariff bond that is not a U.S. holder but does not include (i) an entity or arrangement treated as a partnership for U.S. federal income tax purposes, (ii) a former citizen of the United States, or (iii) a former resident of the United States.

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes is a holder of a securitized utility tariff bond, the U.S. federal income tax treatment of a partner will generally depend on the status of the partner and the activities of the partnership. Partners are encouraged to consult their tax advisors about the particular U.S. federal income tax consequences applicable to them. Similarly, former citizens and former residents of the United States are encouraged to consult their tax advisors about the particular U.S. federal income tax consequences that may be applicable to them.

DISPOSING OF SECURITIZED UTILITY TARIFF BONDS IN LIGHT OF THEIR PARTICULAR CIRCUMSTANCES, AS WELL AS THE EFFECT OF ANY FOREIGN, STATE, LOCAL OR OTHER LAWS.

Taxation of the Issuing Entity and Characterization of the Securitized Utility Tariff Bonds

Based upon Revenue Procedure 2005-62 and certain representations from us, including a representation by us that we will not make, or allow there to be made, any election to the contrary, Sidley Austin LLP expects to render its opinion that for U.S. federal income tax purposes (i) the issuing entity will not be treated as a taxable entity separate and apart from our sole member, Atmos Energy, and (ii) the securitized utility tariff bonds will constitute indebtedness of Atmos. This opinion is based on certain representations made by us and Atmos Energy, on the application of current law to the facts as established by the Indenture and other relevant documents and assumes compliance with the Indenture and such other documents as in effect on the date of issuance of the securitized utility tariff bonds.

Tax Consequences to U.S. Holders

Payments of Interest.

Interest on the securitized utility tariff bonds will be taxable as ordinary interest income when received or accrued by U.S. holders, depending upon their method of accounting. This discussion assumes that the securitized utility tariff bonds will not be considered to be issued with original issue discount (“OID”). OID is generally defined as any excess of the stated price the U.S. holder will receive upon redemption of the bond at the bond’s maturity, less the price the U.S. holder pays to purchase the bond, if this difference is equal to or greater than a de minimis amount. If the securitized utility tariff bonds are issued with OID, prospective U.S. holders will be so informed in the related prospectus and should thereafter consult their tax adviser to determine the federal, state, local and foreign income and any other tax consequences.

Sale or Other Taxable Disposition of the Securitized Utility Tariff Bonds.

If there is a sale, exchange, redemption, retirement or other taxable disposition of a securitized utility tariff bond, a U.S. holder generally will recognize taxable gain or loss equal to the difference between (a) the amount of cash and the fair market value of any other property received (other than amounts attributable to, and taxable as, accrued stated interest), and (b) the holder’s adjusted tax basis in the securitized utility tariff bond. A U.S. holder’s adjusted tax basis in a securitized utility tariff bond generally will equal its cost, reduced by any payments reflecting principal previously received with respect to the bond. Gain or loss generally will be capital gain or loss if the securitized utility tariff bond is held as a capital asset and will be long-term capital gain or loss if the securitized utility tariff bond was held for more than one year at the time of disposition. If a U.S. holder sells a securitized utility tariff bond between interest payment dates, a portion of the amount received will reflect interest that has accrued on the securitized utility tariff bond but that has not yet been paid by the sale date and, to the extent that amount has not already been included in the U.S. holder’s income, it will be treated as ordinary interest income and not as capital gain.

3.8% Tax on “Net Investment Income”

Certain U.S. holders will be subject to an additional 3.8% tax on all or a portion of their “net investment income,” which may include the interest payments and any taxable gain realized with respect to a securitized utility tariff bond subject to certain limitations and exceptions. U.S. holders are encouraged to consult their tax advisors with respect to this tax.

Information Reporting and Backup Withholding

Payments of stated interest and the proceeds of a disposition of securitized utility tariff bonds may be reported to the IRS. These information reporting requirements do not apply with respect to certain exempt U.S. holders, such as corporations, that have certified to that status as required.

123

##### Table of Contents

Backup withholding may apply to payments of the foregoing amounts, unless a U.S. holder provides the applicable withholding agent with its taxpayer identification number, certified under penalties of perjury, as well as certain other information, or otherwise establishes an exemption from backup withholding. Backup withholding will also apply if a U.S. holder is notified by the IRS that the U.S. holder is subject to backup withholding because of its failure to report payment of interest and dividends properly, or if the U.S. holder otherwise fails to comply with the applicable backup withholding rules.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will be allowed as a credit against a U.S. holder’s U.S. federal income tax liability, if any, and may entitle a U.S. holder to a refund, provided the required information is timely furnished to the IRS.

Tax Consequences to Non-U.S. Holders

Withholding Tax on Interest Payments

Subject to the discussion below (see “—Reporting and Backup Withholding” and “—The Foreign Account Tax Compliance Act”), payments of interest income on the securitized utility tariff bonds to a non-U.S. holder generally will be exempt from U.S. federal income and withholding tax under the “portfolio interest” exemption if the interest is not effectively connected with the non-U.S. holder’s U.S. trade or business, the non-U.S. holder properly certifies as to its non-U.S. status, as described below, and the non-U.S. holder:

| • |  | does not actually or constructively own 10% or more of the total combined voting power of all classes of Atmos Energy stock that are entitled to vote;

| • |  | is not a bank whose receipt of interest is in connection with an extension of credit made pursuant to a loan agreement entered into in the ordinary course of business; and

| • |  | is not a “controlled foreign corporation” for U.S. federal income tax purposes that is related to us or Atmos Energy actually or constructively.

The portfolio interest exemption applies only if the non-U.S. holder appropriately certifies as to its non-U.S. status to the applicable withholding agent and that withholding agent does not have actual knowledge or reason to know that the non-U.S. holder in fact a United States person. A holder generally can meet this certification requirement by providing a properly executed IRS Form W-8BEN or W-8BEN-E, as applicable (or appropriate substitute or successor form) to the applicable withholding agent. If the non-U.S. holder holds the securitized utility tariff bonds through a financial institution or other agent acting on its behalf, it may be required to provide appropriate certifications to its agent. The agent then generally will be required to provide appropriate certifications to the applicable withholding agent, either directly or through other intermediaries.

If the non-U.S. holder cannot satisfy the requirements described above, payments of interest made to the non-U.S. holder will be subject to U.S. federal withholding tax, currently at a 30% rate, unless (1) it provides the applicable withholding agent with a properly executed IRS Form W-8BEN or W-8BEN-E, as applicable (or appropriate substitute or successor form) claiming an exemption from (or a reduction of) withholding under an applicable income tax treaty or (2) the payments of interest are effectively connected with its conduct of a trade or business in the United States and it meets the certification requirements described below (see “—Income or Gain Effectively Connected with a U.S. Trade or Business”).

124

##### Table of Contents

Disposition of the Securitized Utility Tariff Bonds

Subject to the discussion below (see “—Reporting and Backup Withholding” and “—The Foreign Account Tax Compliance Act”), a non-U.S. holder generally will not be subject to United States federal income or withholding tax on gain realized on the sale, redemption, exchange, retirement or other taxable disposition of securitized utility tariff bonds, unless:

| • |  | the gain is effectively connected with the conduct by the non-U.S. holder of a trade or business in the United States (and, if required by an applicable income tax treaty, is attributable to a permanent establishment maintained by the non-U.S. holder in the United States); or

| • |  | the non-U.S. holder is an individual who is present in the United States for 183 days or more during the taxable year and certain other requirements are met.

If you are a non-U.S. holder described in the first bullet point above, you generally will be subject to U.S. federal income tax as described below (see “—Income or Gain Effectively Connected with a U.S. Trade or Business”). If you are a non-U.S. holder described in the second bullet point above, you generally will be subject to U.S. federal income tax at a 30% rate (or a lower applicable income tax treaty rate) on the gain derived from the sale, redemption, exchange, retirement or other taxable disposition, which may be offset by certain U.S.-source capital losses, unless an applicable income tax treaty provides otherwise.

To the extent any portion of the amount realized on the sale, redemption, exchange, retirement or other taxable disposition of the securitized utility tariff bonds is attributable to accrued but unpaid interest on the securitized utility tariff bond, this amount will generally be taxed in the same manner as described above in “—Interest Payments.”

Income or Gain Effectively Connected with a U.S. Trade or Business

If any interest on the securitized utility tariff bonds or gain from a sale, redemption, exchange, retirement or other taxable disposition of the securitized utility tariff bonds is effectively connected with a U.S. trade or business conducted by a non-U.S. holder, then the non-U.S. holder generally will be subject to U.S. federal income tax on such interest or gain on a net income basis in the same manner as a U.S. holder (unless an applicable income tax treaty provides otherwise). If interest on the securitized utility tariff bonds or gain from a sale, redemption, exchange, retirement or other taxable disposition is effectively connected income, the U.S. federal withholding tax described will generally not apply (assuming appropriate certification is provided) unless an applicable income tax treaty provides otherwise. A non-U.S. holder generally can meet the certification requirements by providing a properly executed IRS Form W-8ECI (or other applicable form) to the applicable withholding agent. In addition, if the non-U.S. holder is a corporation for U.S. federal income tax purposes, that portion of its earnings and profits that is attributable to such effectively connected income or gain, subject to certain adjustments, may be subject to a “branch profits tax” at a 30% rate (or a lower applicable income tax treaty rate).

Reporting and Backup Withholding

Payments to a non-U.S. holder of interest on a securitized utility tariff bond, and amounts withheld from such payments, if any, generally will be required to be reported to the IRS and may also be made available to the tax authorities of the country in which a non-U.S. holder is a tax resident under the provisions of an applicable income tax treaty or agreement. Backup withholding generally will not apply to payments of interest to a non-U.S. holder if the certification described in “—Withholding Tax on Interest Payments” above is provided by the non-U.S. holder, or the non-U.S. holder otherwise establishes an exemption.

Proceeds from a disposition of a securitized utility tariff bond effected by the U.S. office of a U.S. or non-U.S. broker will be subject to information reporting requirements and backup withholding unless a non-U.S.

125

##### Table of Contents

holder properly certifies, under penalties of perjury, as to its non-U.S. status and certain other conditions are met, or an exemption is otherwise established. Information reporting and backup withholding generally will not apply to any proceeds from a disposition of a securitized utility tariff bond effected outside the United States by a non-U.S. office of a broker, unless such broker has certain connections to the United States, in which case information reporting, but not backup withholding, may apply unless certain other conditions are met, or an exemption is otherwise established.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will be allowed as a credit against a non-U.S. holder’s U.S. federal income tax liability, if any, and may entitle a non-U.S. holder to a refund, provided the required information is timely furnished to the IRS.

The Foreign Account Tax Compliance Act

The Foreign Account Tax Compliance Act (“FATCA”) generally imposes a U.S. federal withholding tax (separate and apart from, but without duplication of, the withholding tax described above) at a rate of 30% on payments of U.S. source interest on, and the gross proceeds from a disposition of, certain debt obligations paid to certain non-U.S. entities, including certain foreign financial institutions and investment funds (including, in some instances, where such an entity is acting as an intermediary), unless such non-U.S. entity complies with certain withholding and reporting requirements. Pursuant to proposed U.S. Treasury Regulations (upon which taxpayers are permitted to rely until they are revoked or final U.S. Treasury Regulations are issued), this withholding tax generally will not apply to the gross proceeds from a sale or other disposition of instruments, such as the securitized utility tariff bonds, that produce U.S. source interest. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States with respect to these rules may be subject to different rules. Under certain circumstances, a beneficial owner of a securitized utility tariff bond may be eligible for a refund or credit of such taxes. Prospective purchasers are encouraged to consult their tax advisors regarding the application of FATCA in their particular circumstances.

The preceding discussion of certain U.S. federal income tax consequences is for general information only and is not tax advice. Each prospective investor should consult its own tax advisor regarding the particular U.S. federal, state, local and non-U.S. tax consequences of acquiring, owning and disposing of the securitized utility tariff bonds, including the consequences of any proposed change in applicable laws.

MATERIAL KANSAS INCOME TAX CONSEQUENCES

Triplett Woolf Garretson, LLC, counsel to us and Atmos Energy, expects to issue an opinion, that (i) assuming that the securitized utility tariff bonds will be treated as debt obligations of Atmos Energy for U.S. federal income tax purposes, interest paid on the securitized utility tariff bonds generally will be taxed for Kansas income tax purposes consistently with its taxation for U.S. federal income tax purposes and such interest received by an entity or person not otherwise subject to Kansas corporate or individual income tax will not be subject to Kansas income tax; (ii) assuming that such treatment applies for U.S. federal income tax purposes, for Kansas income tax purposes, we will not be treated as a taxable entity separate and apart from Atmos Energy; and (iii) assuming that such treatment applies for U.S. federal income tax purposes, for Kansas income tax purposes, the securitized utility tariff bonds will constitute indebtedness of Atmos Energy. These opinions are not binding on any taxing authority or any court, and there can be no assurance that contrary positions may not be taken by any taxing authority.

This discussion is based on current provisions of the Kansas tax statutes and regulations, judicial decisions and administrative interpretations and rulings. All of these authorities and interpretations are subject to change, and any change may apply retroactively and affect the accuracy of the opinions set forth in this discussion.

The discussion under “MATERIAL KANSAS INCOME TAX CONSEQUENCES” is for general information only and may not be applicable depending upon a bondholder’s particular situation. It is recommended that prospective bondholders consult their own tax advisors with respect to the tax consequences to them of the acquisition, ownership and disposition of the securitized utility tariff bonds, including the tax consequences under federal, state, local, non-U.S. and other tax laws and the effects of changes in such laws.

ERISA CONSIDERATIONS

General

The Employee Retirement Income Security Act of 1974, known as ERISA, and Section 4975 of the Internal Revenue Code impose certain requirements on employee benefit plans and other arrangements subject to ERISA or Section 4975 of the Internal Revenue Code. ERISA and the Internal Revenue Code also impose certain requirements on fiduciaries of such plans in connection with the investment of the assets of the plans. For purposes of this discussion, “plans” include employee benefit plans and other plans and arrangements that are subject to ERISA or Section 4975 of the Code that provide retirement income, including individual retirement accounts and annuities and Keogh plans, as well as some collective investment funds and insurance company general or separate accounts in which the assets of those plans, accounts or arrangements are invested. A fiduciary of an investing plan is any person who in connection with the assets of the plan:

| • |  | has discretionary authority or control over the management or disposition of assets; or

| • |  | provides investment advice for a fee.

Some plans, such as governmental plans, and certain church plans, and the fiduciaries of those plans, are not subject to ERISA requirements or Section 4975 of the Code. Accordingly, assets of these plans may be invested in the securitized utility tariff bonds without regard to the ERISA considerations described below, subject to the provisions of other applicable federal, state and local law that is similar to the provisions of Title I of ERISA and Section 4975 of the Code (“applicable similar law”). In addition, any such plan may be subject to other provisions of federal law, including, for example, a plan which is qualified and exempt from taxation under Sections 401(a) and 501(a) of the Internal Revenue Code, which is subject to the prohibited transaction rules in Section 503 of the Internal Revenue Code.

ERISA imposes certain general fiduciary requirements on fiduciaries, including:

| • |  | investment prudence and diversification; and

| • |  | the investment of the assets of the plan in accordance with the documents governing the plan.

Section 406 of ERISA and Section 4975 of the Internal Revenue Code also prohibit a broad range of transactions involving the assets of a plan and persons who have certain specified relationships to the plan, referred to as “parties in interest,” as defined under ERISA or “disqualified persons” as defined under Section 4975 of the Internal Revenue Code unless a statutory or administrative exemption is available. The types of transactions that are prohibited include but are not limited to:

| • |  | sales, exchanges or leases of property;

| • |  | loans or other extensions of credit; and

| • |  | the furnishing of goods or services.

Certain persons that participate in a prohibited transaction may be subject to an excise tax under Section 4975 of the Internal Revenue Code or a penalty imposed under Section 502(i) of ERISA, unless a statutory or administrative exemption is available. In addition, the persons involved in the prohibited transaction may have to cancel or unwind the transaction and a fiduciary of the plan may have to pay an amount to the plan for any losses realized by the plan or profits realized by these persons. In addition, individual retirement accounts involved in the prohibited transaction may be disqualified which would result in adverse tax consequences to the owner of the account.

Regulation of Assets Included in a Plan

A fiduciary’s investment of the assets of a plan that is subject to Title I of ERISA or Section 4975 of the Code in the securitized utility tariff bonds may cause our assets to be deemed assets of the investing plan. United States Department of Labor regulations at 29 C.F.R. Section 2510.3-101, as modified by Section 3(42) of ERISA

128

##### Table of Contents

(collectively, the “plan asset regulations”), provide that the assets of an entity will be deemed to be assets of a plan that purchases an interest in the entity if the interest that is purchased by the plan is an equity interest, equity participation by “benefit plan investors” is “significant” (as those terms are defined in the plan asset regulations) and none of the other exceptions contained in the plan asset regulations applies. An equity interest is defined in the plan asset regulations as an interest in an entity other than an instrument which is treated as indebtedness under applicable local law and which has no substantial equity features. Although there is no authority directly on point, it is anticipated that the securitized utility tariff bonds will be treated as indebtedness under local law without any substantial equity features.

If the securitized utility tariff bonds were deemed to be equity interests in us and none of the exceptions contained in the plan asset regulations were applicable, then our assets would be considered to be assets of any plans that acquire the securitized utility tariff bonds. The extent to which the securitized utility tariff bonds are owned by benefit plan investors will not be monitored. If our assets were deemed to constitute “plan assets” pursuant to the plan asset regulations, transactions we might enter into, or may have entered into in the ordinary course of business, might constitute non-exempt prohibited transactions under ERISA and or Section 4975 of the Internal Revenue Code.

In addition, the acquisition, holding or disposition of the securitized utility tariff bonds by or on behalf of a plan could give rise to a prohibited transaction if we or the trustee, Atmos Energy, any other servicer, any underwriter or certain of their affiliates is or becomes a “party in interest” or “disqualified person” with respect to an investing plan. Each purchaser of the securitized utility tariff bonds will be deemed to have represented and warranted by virtue of its acquisition of any securitized utility tariff bonds that its acquisition, holding and disposition of the securitized utility tariff bonds will not result in a non-exempt prohibited transaction under ERISA, Section 4975 of the Internal Revenue Code or, in the case of a plan subject to applicable similar law, a non-exempt violation of applicable similar law.

Before acquiring any securitized utility tariff bonds by or on behalf of a plan or a plan subject to applicable similar law, you should consider whether the acquisition, holding and disposition of securitized utility tariff bonds might constitute or result in a non-exempt prohibited transaction under ERISA, Section 4975 of the Internal Revenue Code or, in the case of a plan subject to applicable similar law, a non-exempt violation of applicable similar law and, if so, whether one or more prohibited transaction exemptions or similar law exemptions, as the case may be, might apply to the acquisition, holding and disposition of the securitized utility tariff bonds.

Prohibited Transaction Exemptions

If you are a fiduciary of a plan subject to Title I of ERISA or Section 4975 of the Code, before acquiring any securitized utility tariff bonds, you should consider the availability of one of the Department of Labor’s prohibited transaction class exemptions, referred to as PTCEs, or one of the statutory exemptions provided by ERISA or Section 4975 of the Internal Revenue Code, which include:

| • |  | PTCE 75-1, which exempts certain transactions between a plan and certain broker-dealers, reporting dealers and banks;

| • |  | PTCE 84-14, which exempts certain transactions effected on behalf of a plan by a “qualified professional asset manager;”

| • |  | PTCE 90-1, which exempts certain transactions between insurance company separate accounts and parties in interest;

| • |  | PTCE 91-38, which exempts certain transactions between bank collective investment funds and parties in interest;

| • |  | PTCE 95-60, which exempts certain transactions between insurance company general accounts and parties in interest;

| • |  | PTCE 96-23, which exempts certain transactions effected on behalf of a plan by an “in-house asset manager;” and

| • |  | the statutory service provider exemption provided by Section 408(b)(17) of ERISA and Section 4975(d)(20) of the Internal Revenue Code, which exempts certain transactions between plans and parties in interest that are not fiduciaries with respect to the transaction.

We cannot provide any assurance that any of these class exemptions or statutory exemptions will apply with respect to any particular investment in the securitized utility tariff bonds by, or on behalf of, a plan or, even if it were deemed to apply, that any exemption would apply to all transactions that may occur in connection with the investment. Even if one of these class exemptions or statutory exemptions were deemed to apply, securitized utility tariff bonds may not be purchased with assets of any plan if we or the trustee, Atmos Energy, any other servicer, any underwriter or any of their affiliates:

| • |  | has investment discretion over the assets of the plan used to purchase the securitized utility tariff bonds; or

| • |  | has authority or responsibility to give, or regularly gives, investment advice regarding the assets of the plan used to purchase the securitized utility tariff bonds, for a fee and under an agreement or understanding that the advice will serve as a primary basis for investment decisions for the assets of the plan, and will be based on the particular investment needs of the plan.

Consultation with Counsel

The sale of the securitized utility tariff bonds to a plan or a plan subject to applicable similar law will not constitute a representation by us or the trustee, Atmos Energy, any other servicer, any underwriter or any of their affiliates that such an investment meets all relevant legal requirements relating to investments by such plans generally or by any particular plan, or that such an investment is appropriate for such plans generally or for a particular plan.

If you are a fiduciary which proposes to purchase the securitized utility tariff bonds on behalf of or with assets of a plan subject to ERISA or Section 4975 of the Code or a plan subject to applicable similar law, you should consider your general fiduciary obligations under ERISA, or applicable similar law, and you should consult with your legal counsel as to the potential applicability of ERISA, the Internal Revenue Code and applicable similar law to any investment and the availability of any prohibited transaction exemption under ERISA or Section 4975 of the Code, or, in the case of a plan subject to similar law, any exemption from a violation of similar law, in connection with any investment.

This summary is based on current provisions of ERISA, the Internal Revenue Code, the regulations thereunder and other related guidance. All of these authorities and interpretations are subject to change, and any change may apply retroactively and affect the accuracy of the opinions, statements and conclusions set forth in this discussion.

RATINGS FOR THE SECURITIZED UTILITY TARIFF BONDS

We expect that the securitized utility tariff bonds will receive credit ratings from two NRSROs. A security rating is not a recommendation to buy, sell or hold securities and may be subject to revision or withdrawal at any time by the assigning NRSRO. Each rating should be evaluated independently of any other rating. No person or entity is obligated to maintain the rating on the securitized utility tariff bonds and, accordingly, we can give no assurance that the ratings assigned to the securitized utility tariff bonds upon initial issuance will not be lowered or withdrawn by a NRSRO at any time thereafter. If a rating of the securitized utility tariff bonds is lowered or withdrawn, the liquidity of the securitized utility tariff bonds may be adversely affected. In general, ratings address credit risk and do not represent any assessment of any particular rate of principal payments on the securitized utility tariff bonds other than the payment in full of the securitized utility tariff bonds by the final maturity date, as well as the timely payment of interest.

Under Rule 17g-5 under the Exchange Act, NRSROs providing the sponsor with the requisite certification will have access to all information posted on a website by the sponsor for the purpose of determining the initial rating and monitoring the rating after the securitized utility tariff bonds issuance date. As a result, an NRSRO other than the NRSROs hired by the sponsor may issue Unsolicited Ratings, which may be lower, and could be significantly lower, than the ratings assigned by the hired NRSROs. The Unsolicited Ratings may be issued prior to, or after, the securitized utility tariff bonds issuance date. Issuance of any Unsolicited Rating will not affect the issuance of the securitized utility tariff bonds. Issuance of an Unsolicited Rating lower than the ratings assigned by the hired NRSROs on the securitized utility tariff bonds might adversely affect the value of the securitized utility tariff bonds and, for regulated entities, could affect the status of the securitized utility tariff bonds as a legal investment or the capital treatment of the securitized utility tariff bonds. Investors in the securitized utility tariff bonds should consult with their legal counsel regarding the effect of the issuance of a rating by a non-hired NRSRO that is lower than the rating of a hired NRSRO.

A portion of the fees paid by Atmos Energy to a NRSRO that is hired to assign a rating on the securitized utility tariff bonds is contingent upon the issuance of the securitized utility tariff bonds. In addition to the fees paid by Atmos Energy to a NRSRO at closing, Atmos Energy will pay a fee to the NRSRO for ongoing surveillance for so long as the securitized utility tariff bonds are outstanding. However, no NRSRO is under any obligation to continue to monitor or provide a rating on the securitized utility tariff bonds.

INVESTMENT COMPANY ACT OF 1940 AND VOLCKER RULE MATTERS

We expect to rely on an exception from the definition of “investment company” under the Investment Company Act of 1940, as amended (the “1940 Act”), contained in Section 3(c)(5)(A) under the 1940 Act, although there may be additional exceptions or exemptions available to us. As a result of such exemption, we should not be required to register as an “investment company” under the 1940 Act.

In addition, we are being structured so as not to constitute a “covered fund” for purposes of the Volcker Rule, under the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”). As part of the Dodd-Frank Act, federal law prohibits a “banking entity,” which is broadly defined to include banks, bank holding companies and affiliates thereof, from engaging in proprietary trading or holding ownership interests in certain private funds. The definition of “covered fund” in the regulations adopted to implement the Volcker Rule includes (generally) any entity that would be an investment company under the 1940 Act but for the exceptions provided under Sections 3(c)(1) or 3(c)(7) thereunder. Because we expect to rely on Section 3(c)(5)(A) under the 1940 Act, we expect to not be considered a “covered fund” within the meaning of the Volcker Rule regulations.

Item 13. Indemnification of Directors and Officers

The LLC Agreement provides that we shall, to the fullest extent permitted by law, indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the Issuing Entity) by reason of the fact that he or she is or was a director, manager, officer, employee or agent of us, or is or was serving at the request of us as a manager, director, officer, employee or agent of another company, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement in connection with such action, suit or proceeding actually and reasonably incurred by such person, if such person acted in good faith and in a manner which such person reasonably believed to be in or not opposed to the best interests of us, and, with respect to any criminal action or proceeding, had no reasonable cause to believe such conduct was unlawful; provided that such person shall not be entitled to indemnification if such judgment, penalty, fine or other expense was directly caused by such person’s fraud, gross negligence or willful misconduct. The LLC Agreement provides that expenses incurred in defending or investigating a threatened or pending action, suit or proceeding may be paid by us in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of the manager, director, officer, employee or agent to repay such amount if it shall ultimately be determined that he or she is not entitled to be indemnified by us as authorized in the LLC Agreement.

ATMOS ENERGY CORPORATION

The Texas Business Organizations Code and the Virginia Stock Corporation Act permit, and in some cases require, corporations to indemnify directors and officers who are or have been a party or are threatened to be made a party to litigation against judgments, penalties, including excise and similar taxes, fines, settlements, and

II-1

##### Table of Contents

reasonable expenses under certain circumstances. Article IX of Atmos Energy’s Articles of Incorporation and Article IX of Atmos Energy’s Bylaws provide for indemnification of judgments, penalties, including excise and similar taxes, fines, settlements, and reasonable expenses, including attorney’s fees, and the advance payment or reimbursement of such reasonable expenses to directors and officers to the fullest extent permitted by law.

As authorized by Section 8.101 of the Texas Business Organizations Code, and Section 13.1-697 of the Virginia Stock Corporation Act, each of Atmos Energy’s directors and officers may be indemnified by Atmos Energy against expenses, including attorney’s fees, judgments, fines and amounts paid in settlement, actually and reasonably incurred in connection with the defense or settlement of any threatened, pending or completed legal proceedings in which such person is involved by reason of the fact that such person is or was a director or officer of Atmos Energy if such person acted in good faith and in a manner that such person reasonably believed to be in or not opposed to Atmos Energy’s best interests, and, with respect to any criminal action or proceeding, if such person had no reasonable cause to believe that such person’s conduct was unlawful. In each case, such indemnity shall be to the fullest extent authorized by the Texas Business Organizations Code and the Virginia Stock Corporation Act. If the director or officer is found liable to Atmos Energy, or received an improper personal benefit from Atmos Energy, whether or not involving action in such person’s official capacity, then indemnification will be limited to reasonable expenses actually incurred.

Article X of Atmos Energy’s Articles of Incorporation provides that no director shall be personally liable to Atmos Energy or its shareholders for monetary damages for any breach of fiduciary duty as a director except for liability:

| • |  | for any breach of duty of loyalty to Atmos Energy or its shareholders;

| • |  | for an act or omission not in good faith or which involves intentional misconduct or a knowing violation of law;

| • |  | for a transaction from which the director received an improper benefit, whether or not the benefit resulted from an action taken within the scope of the director’s office;

| • |  | for an act or omission for which the liability of a director is expressly provided by statute; or

| • |  | for an act related to an unlawful stock repurchase or payment of a dividend.

In addition, Article IX of Atmos Energy’s Articles of Incorporation and Article IX of Atmos Energy’s Bylaws require us to indemnify to the fullest extent authorized by law any person made or threatened to be made party to any action, suit or proceeding, whether criminal, civil, administrative, arbitrative or investigative, by reason of the fact that such person is or was a director or officer or, while a director or officer, serves or served at Atmos Energy’s request as a director, officer, partner, venturer, proprietor, trustee, employee, agent or similar functionary of any other enterprise.

Atmos Energy maintains an officers’ and directors’ liability insurance policy insuring officers and directors against certain liabilities, including liabilities under the Securities Act of 1933. The effect of such policy is to indemnify such officers and directors against losses incurred by them while acting in such capacities.

Item 15. Undertakings

The undersigned registrants hereby undertake that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that

II-3

##### Table of Contents

time shall be deemed to be the initial bona fide offering thereof.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrants pursuant to the foregoing provisions, or otherwise, each registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by a registrant of expenses incurred or paid by a director, officer or controlling person of such registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, each registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.

The undersigned registrants hereby undertake that:

(1) For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

(2) For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
