The information that we file later with the SEC under Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act and before the termination of this offering will automatically update and supersede previous information included or incorporated by reference in this prospectus supplement and the accompanying prospectus.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS
 
Statements contained or incorporated by reference in this prospectus supplement and the accompanying prospectus that are not statements of historical fact are “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended. Forward-looking statements are based on management’s beliefs as well as assumptions made by, and information currently available to, management. Because such statements are based on expectations as to future results and are not statements of fact, actual results may differ materially from those stated. Important factors that could cause future results to differ include, but are not limited to:
 
  •  our ability to continue to access the credit markets to satisfy our liquidity requirements;
 
  •  the impact of economic conditions on our customers;
 
  •  increased costs of providing pension and post-retirement health care benefits and increased funding requirements;
 
  •  market risks beyond our control affecting our risk management activities, including market liquidity, commodity price volatility, increasing interest rates and counterparty creditworthiness;
 
  •  regulatory trends and decisions, including the impact of rate proceedings before various state regulatory commissions;
 
  •  increased federal regulatory oversight and potential penalties;
 
  •  the impact of environmental regulations on our business;
 
  •  the concentration of our distribution, pipeline and storage operations in Texas;
 
  •  adverse weather conditions;
 
  •  the effects of inflation and changes in the availability and prices of natural gas;
 
  •  the capital-intensive nature of our natural gas distribution business;
 
  •  increased competition from energy suppliers and alternative forms of energy;
 
  •  the inherent hazards and risks involved in operating our natural gas distribution business;
 
  •  natural disasters, terrorist activities or other events; and
 
  •  other risks and uncertainties discussed in this prospectus supplement, any accompanying prospectus and our other filings with the SEC.
 
All of these factors are difficult to predict and many are beyond our control. Accordingly, while we believe these forward-looking statements to be reasonable, there can be no assurance that they will approximate actual experience or that the expectations derived from them will be realized. When used in our documents or oral presentations, the words “anticipate,” “believe,” “estimate,” “expect,” “forecast,” “goal,” “intend,” “objective,” “plan,” “projection,” “seek,” “strategy” or similar words are intended to identify forward-looking statements. We undertake no obligation to update or revise any of our forward-looking statements, whether as a result of new information, future events or otherwise.
 
For additional factors you should consider, please see “Risk Factors” on page S-6 of this prospectus supplement and Sections “Item 1A. Risk Factors” and “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our annual report on Form 10-K for the fiscal year ended September 30, 2008 and “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our quarterly report on Form 10-Q for the three-month period ended December 31, 2008. See “Incorporation of Certain Documents by Reference.”

PROSPECTUS SUPPLEMENT SUMMARY
 
You should read the following summary in conjunction with the more detailed information contained elsewhere in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference in this prospectus supplement and the accompanying prospectus.
 
Atmos Energy Corporation
 
Atmos Energy Corporation is engaged primarily in the regulated natural gas distribution and transmission and storage businesses, as well as other nonregulated natural gas businesses. We are one of the country’s largest natural gas-only distributors based on number of customers. We distribute natural gas through sales and transportation arrangements to approximately 3.2 million residential, commercial, public authority and industrial customers in 12 states. We also operate one of the largest intrastate pipelines in Texas based upon miles of pipe.
 
Through our regulated transmission and storage business, we provide natural gas transportation and storage services to our Mid-Tex Division, our largest natural gas distribution division located in Texas, and for third parties. Additionally, we provide ancillary services customary to the pipeline industry, including parking arrangements, lending and sales of inventory on hand.
 
Through our nonregulated businesses, we primarily provide natural gas management and marketing services to municipalities, other local gas distribution companies and industrial customers primarily in the Midwest and Southeast. We also provide storage services to some of our natural gas distribution divisions and to third parties.
 
We operate Atmos Energy through the following four segments:
 
  •  the natural gas distribution segment, which includes our regulated natural gas distribution and related sales operations;
 
  •  the regulated transmission and storage segment, which includes the regulated pipeline and storage operations of our Atmos Pipeline — Texas Division;
 
  •  the natural gas marketing segment, which includes a variety of nonregulated natural gas management services; and
 
  •  the pipeline, storage and other segment, which is comprised of our nonregulated natural gas gathering, transmission and storage services.
 
We have experienced more than 20 consecutive years of increasing dividends and earnings growth after giving effect to our acquisitions. Historically, we achieved this record of growth through acquisitions while efficiently managing our operating and maintenance expenses and leveraging our technology, such as our 24-hour call centers, to achieve more efficient operations. Our last significant acquisition occurred in October 2004 with the purchase of the natural gas distribution and pipeline operations of TXU Gas Company (TXU Gas). The TXU Gas acquisition essentially doubled our number of natural gas distribution customers, by adding approximately 1.5 million gas customers in Texas, including the Dallas-Fort Worth metropolitan area and the northern suburbs of Austin. The acquisition also added approximately 6,100 miles of gas transmission and gathering lines and five underground storage reservoirs, all within Texas. In recent years, we have also achieved growth by implementing rate designs that reduce or eliminate regulatory lag and separate the recovery of our approved margins from customer usage patterns. In addition, we have developed various commercial opportunities within our regulated transmission and storage operations. Finally, we have strengthened our nonregulated businesses by increasing sales volumes and actively pursuing opportunities to increase the amount of storage available to us.

Summary Financial Data
 
The following table presents summary consolidated and segment financial data of Atmos Energy Corporation for the periods and as of the dates indicated. We derived the summary financial data for the fiscal years ended September 30, 2008, 2007, 2006, 2005 and 2004 from our audited consolidated financial statements and the summary financial data for the three months ended December 31, 2008 and 2007 from our unaudited condensed consolidated financial statements. Please note that, given the inherent seasonality in our business, the results of operations for the three months ended December 31, 2008 presented below are not necessarily indicative of results for the entire fiscal year. The information is only a summary and does not provide all of the information contained in our financial statements. Therefore, you should read the information presented below in conjunction with “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our consolidated financial statements and related notes included in our annual report on Form 10-K for the fiscal year ended September 30, 2008, and “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our condensed consolidated financial statements and related notes included in our quarterly report on Form 10-Q for the three-month period ended December 31, 2008, each of which is incorporated by reference in this prospectus supplement and the accompanying prospectus. Our operating results include the impact of the acquisition of TXU Gas in October 2004. As a result, our consolidated financial data presented below include results from operations of TXU Gas from October 2004; therefore, comparisons with the fiscal year ended September 30, 2004 may not be meaningful.

(4) Effective September 30, 2008, we classified our cash collateral or the obligation to return cash into risk management assets and/or liabilities, as appropriate, in accordance with FSP FIN 39-1. Total assets as of December 31, 2007 and September 30, 2007, 2005 and 2004 also reflect this new classification. This reclassification had no impact on total assets as of September 30, 2006 and it did not impact our financial position, results of operations or cash flows for any of the periods presented above.

(6) Restated to conform to current segment reporting.
 
(7) For purposes of computing ratio of earnings to fixed charges, earnings consist of the sum of our pretax income from continuing operations and fixed charges. Fixed charges consist of interest expense, amortization of debt discount, premium and expense, capitalized interest and a portion of lease payments considered to represent an interest factor.
 
(8) The pro forma ratio of earnings to fixed charges gives effect to the issuance of the notes, the redemption of our $400 million 4.00% Senior Notes due 2009 (assuming a redemption date of May 1, 2009) and the settlement of the Treasury lock agreement described in “Use of Proceeds” as of the beginning of the periods indicated.

The notes will rank equally in right of payment with all our existing and future unsubordinated indebtedness and will rank senior in right of payment to any future indebtedness that is subordinated to the notes. The notes will be effectively subordinated to all our existing and future secured indebtedness to the extent of the assets securing such indebtedness and to the indebtedness and liabilities of our subsidiaries.
 
Optional Redemption We may redeem the notes prior to maturity at our option, at any time in whole or from time to time in part, at a redemption price equal to the greater of the principal amount of the notes to be redeemed and the “make-whole” redemption price, plus, in each case, accrued and unpaid interest, if any, to the redemption date, as described in “Description of the Notes — Optional Redemption” on page S-14.
 
Covenants of the Indenture We will issue the notes under an indenture which will, among other things, restrict our ability to create liens and to enter into sale and leaseback transactions. See “Description of Debt Securities — Covenants” beginning on page 8 of the accompanying prospectus.
 
Expected Ratings We expect that the notes will be rated “Baa3” by Moody’s Investors Services, “BBB+” by Standard & Poor’s Rating Services, a division of The McGraw-Hill Company, Inc., and “BBB+” by Fitch IBCA, Inc. None of these ratings is a recommendation to buy, sell or hold the notes. Each rating is subject to revision or withdrawal at any time and should be evaluated independently of any other rating.

RISK FACTORS
 
Investing in the notes involves risks. Our business is influenced by many factors that are difficult to predict and beyond our control and that involve uncertainties that may materially affect our results of operations, financial condition or cash flows, or the value of the notes. These risks and uncertainties include those described in the risk factor and other sections of the documents that are incorporated by reference in this prospectus supplement and the accompanying prospectus, including “Item 1A. Risk Factors” in our annual report on Form 10-K for the fiscal year ended September 30, 2008. The risks and uncertainties incorporated by reference are not the only risks and uncertainties we may confront. Moreover, risks and uncertainties not presently known to us or currently deemed immaterial by us may also adversely affect our business, results of operations, financial condition or cash flows, or the value of the notes. You should carefully consider these risks and uncertainties and all of the information contained or incorporated by reference in this prospectus supplement and the accompanying prospectus before you invest in the notes.
 
USE OF PROCEEDS
 
We estimate that we will receive net proceeds from this offering of approximately $      million, after deducting the underwriting discount and estimated offering expenses payable by us. We intend to use the net proceeds from this offering, together with available cash if needed, to redeem our $400 million 4.00% Senior Notes due 2009, which we refer to as the 2009 notes.
 
The 2009 notes mature on October 15, 2009 and the interest rate on the 2009 notes is 4% per year.
 
The terms of the 2009 notes permit us to redeem the 2009 notes in full, at a price equal to the greater of (i) the aggregate principal amount of the 2009 notes and (ii) the present values of the remaining scheduled payments of principal and interest on the 2009 notes discounted to the redemption date at an adjusted treasury rate plus 15 basis points, plus accrued and unpaid interest to the redemption date, upon 30 days notice. If we deliver a notice of redemption to the holders of our 2009 notes with a redemption date of May 1, 2009, the aggregate amount required to redeem the 2009 notes, including accrued and unpaid interest, will be approximately $407 million.
 
If the aggregate principal amount of notes issued in this offering is less than the amount necessary to redeem the 2009 notes, we will use available cash to fund the redemption of the 2009 notes. If the aggregate principal amount of notes issued in this offering is more than the amount necessary to redeem the 2009 notes, we will use the excess cash for general corporate purposes, including the repayment of short-term debt outstanding under our revolving credit facilities. We have been using the proceeds of borrowings under our revolving credit facilities for working capital and other general corporate purposes.
 
In March 2009, we entered into an agreement to fix the Treasury yield component of a notional principal amount of $450 million in notes that could be issued in this offering, which we refer to as the Treasury lock agreement. We intend to terminate and settle the Treasury lock agreement on the closing of this offering. We do not expect to receive any significant amounts in connection with the settlement of the Treasury lock agreement. If the settlement of the Treasury lock agreement results in an obligation, we will use available cash to pay the obligation.

CAPITALIZATION
 
The following table presents our cash and cash equivalents, short-term debt and capitalization as of December 31, 2008, on an actual basis and as adjusted to reflect the issuance of notes in this offering, the redemption of our 2009 notes (assuming a redemption date of May 1, 2009) and the settlement of the Treasury lock agreement. The estimated amount included in the as adjusted column to reflect the settlement of the Treasury lock agreement is not significant. Any increase in the actual value of the Treasury lock agreement from the estimated value will increase the amount of proceeds received from the settlement of the Treasury lock agreement by a corresponding amount. Any decrease in that value will decrease the amount of proceeds received and could result in a decrease in cash and cash equivalents. You should read this table in conjunction with the section entitled “Use of Proceeds” and our condensed consolidated financial statements and related notes included in our quarterly report on Form 10-Q for the three-month period ended December 31, 2008, which is incorporated by reference in this prospectus supplement and the accompanying prospectus.

BUSINESS
 
Overview
 
Atmos Energy Corporation, headquartered in Dallas, Texas, is engaged primarily in the regulated natural gas distribution and transmission and storage businesses, as well as other nonregulated natural gas businesses. We are one of the country’s largest natural gas-only distributors based on number of customers and one of the largest intrastate pipeline operators in Texas based upon miles of pipe.
 
We distribute natural gas through regulated sales and transportation arrangements to approximately 3.2 million residential, commercial, public authority and industrial customers through our six regulated natural gas distribution divisions, which cover service areas in 12 states. Our primary service areas are located in Colorado, Kansas, Kentucky, Louisiana, Mississippi, Tennessee and Texas. We have more limited service areas in Georgia, Illinois, Iowa, Missouri and Virginia. In addition, we transport natural gas for others through our distribution system.
 
Through our regulated transmission and storage business, we provide natural gas transportation and storage services to our Mid-Tex Division, our largest natural gas distribution division located in Texas, and for third parties. Additionally, we provide ancillary services customary to the pipeline industry, including parking arrangements, lending and sales of inventory on hand.
 
Through our nonregulated businesses, we primarily provide natural gas management and marketing services to municipalities, other local gas distribution companies and industrial customers primarily in the Midwest and Southeast. We also provide storage services to some of our natural gas distribution divisions and to third parties.
 
Operating Segments
 
We operate Atmos Energy through the following four segments:
 
  •  the natural gas distribution segment, which includes our regulated natural gas distribution and related sales operations;
 
  •  the regulated transmission and storage segment, which includes the regulated pipeline and storage operations of our Atmos Pipeline — Texas Division;
 
  •  the natural gas marketing segment, which includes a variety of nonregulated natural gas management services; and
 
  •  the pipeline, storage and other segment, which is comprised of our nonregulated natural gas gathering, transmission and storage services.
 
Natural Gas Distribution Segment
 
We operate our natural gas distribution segment through the following six regulated divisions, which are presented below in order of total customers served:
 
  •  Atmos Energy Mid-Tex Division;
 
  •  Atmos Energy Kentucky/Mid-States Division;
 
  •  Atmos Energy Louisiana Division;
 
  •  Atmos Energy West Texas Division;
 
  •  Atmos Energy Mississippi Division; and
 
  •  Atmos Energy Colorado-Kansas Division.
 
The following is a brief description of our natural gas distribution divisions. We operate in our service areas under terms of non-exclusive franchise agreements granted by the various cities and towns that we serve.


S-8


Table of Contents

At September 30, 2008, we held 1,107 franchises having terms generally ranging from five to 35 years. A significant number of our franchises expire each year, which require renewal prior to the end of their terms. We believe that we will be able to renew our franchises as they expire. For more information, see “Item 1. Business” in our annual report on Form 10-K for the fiscal year ended September 30, 2008.
 
Atmos Energy Mid-Tex Division.  Our Mid-Tex Division serves approximately 550 incorporated and unincorporated communities in the north-central, eastern and western parts of Texas, including the Dallas/Fort Worth Metroplex. The governing body of each municipality we serve has original jurisdiction over all gas distribution rates, operations and services within its city limits, except with respect to sales of natural gas for vehicle fuel and agricultural use. The Railroad Commission of Texas (RRC) has exclusive appellate jurisdiction over all rate and regulatory orders and ordinances of the municipalities and exclusive original jurisdiction over rates and services to customers not located within the limits of a municipality.
 
Prior to fiscal 2008, this division operated under one system-wide rate structure. However, in the second quarter of 2008, we reached a settlement with cities representing approximately 80 percent of this division’s customers that will allow us to update rates for customers in these cities through an annual rate review mechanism. Rates for the remaining 20 percent of this division’s customers, including the City of Dallas, continue to be updated through periodic formal rate proceedings and filings made under Texas’ Gas Reliability Infrastructure Program (GRIP). GRIP allows us to include in our rate base annually approved capital costs incurred in the prior calendar year provided that we file a complete rate case at least once every five years.
 
Atmos Energy Kentucky/Mid-States Division.  Our Kentucky/Mid-States Division operates in more than 420 communities across Georgia, Illinois, Iowa, Kentucky, Missouri, Tennessee and Virginia. The service areas in these states are primarily rural; however, this division serves Franklin, Tennessee and other suburban areas of Nashville. We update our rates in this division through periodic formal rate filings made with each state’s public service commission.
 
Atmos Energy Louisiana Division.  In Louisiana, we serve nearly 300 communities, including the suburban areas of New Orleans, the metropolitan area of Monroe and western Louisiana. Direct sales of natural gas to industrial customers in Louisiana who use gas for fuel or in manufacturing processes and sales of natural gas for vehicle fuel are exempt from regulation and are recognized in our natural gas marketing segment. Our rates in this division are updated annually through a stable rate filing without filing a formal rate case.
 
Atmos Energy West Texas Division.  Our West Texas Division serves approximately 80 communities in West Texas, including the Amarillo, Lubbock and Midland areas. Like our Mid-Tex Division, each municipality we serve has original jurisdiction over all gas distribution rates, operations and services within its city limits, with the RRC having exclusive appellate jurisdiction over the municipalities and exclusive original jurisdiction over rates and services to customers not located within the limits of a municipality. Prior to fiscal 2008, rates were updated in this division through formal rate proceedings. However, during 2008, the West Texas Division entered into agreements with its Lubbock and West Texas service areas to update rates for customers in these service areas through an annual rate review mechanism. Rates for the division’s Amarillo service area continue to be updated through periodic formal rate proceedings and filings made under GRIP.
 
Atmos Energy Mississippi Division.  In Mississippi, we serve about 110 communities throughout the northern half of the state, including the Jackson metropolitan area. Our rates in the Mississippi Division are updated annually through a stable rate filing without filing a formal rate case.
 
Atmos Energy Colorado-Kansas Division.  Our Colorado-Kansas Division serves approximately 170 communities throughout Colorado and Kansas and portions of Missouri, including the cities of Olathe, Kansas, a suburb of Kansas City and Greeley, Colorado, located near Denver. We update our rates in this division through periodic formal rate filings made with each state’s public service commission.
 
Regulated Transmission and Storage Segment Overview
 
Our regulated transmission and storage segment consists of the regulated pipeline and storage operations of our Atmos Pipeline — Texas Division. This division transports natural gas to our Mid-Tex Division,


S-9


Table of Contents

transports natural gas for third parties and manages five underground storage reservoirs in Texas. We also provide ancillary services customary in the pipeline industry including parking arrangements, lending and sales of inventory on hand. Parking arrangements provide short-term interruptible storage of gas on our pipeline. Lending services provide short-term interruptible loans of natural gas from our pipeline to meet market demands. These operations represent one of the largest intrastate pipeline operations in Texas with a heavy concentration in the established natural gas-producing areas of central, northern and eastern Texas, extending into or near the major producing areas of the Texas Gulf Coast and the Delaware and Val Verde Basins of West Texas. Nine basins located in Texas are believed to contain a substantial portion of the nation’s remaining onshore natural gas reserves. This pipeline system provides access to all of these basins. Gross profit earned from our Mid-Tex Division and through certain other transportation and storage services is subject to traditional ratemaking governed by the RRC. However, Atmos Pipeline — Texas’ existing regulatory mechanisms allow certain transportation and storage services to be provided under market-based rates with minimal regulation.
 
Natural Gas Marketing Segment Overview
 
Our natural gas marketing activities are conducted through Atmos Energy Marketing (AEM), which is wholly-owned by Atmos Energy Holdings, Inc. (AEH). AEH is a wholly-owned subsidiary of Atmos Energy and operates primarily in the Midwest and Southeast areas of the United States. AEM aggregates and purchases gas supply, arranges transportation and storage logistics and ultimately delivers gas to customers at competitive prices. To facilitate this process, we utilize proprietary and customer-owned transportation and storage assets to provide various services our customers request, including furnishing natural gas supplies at fixed and market-based prices, contract negotiation and administration, load forecasting, gas storage acquisition and management services, transportation services, peaking sales and balancing services, capacity utilization strategies and gas price hedging through the use of financial instruments. As a result, our revenues arise from the types of commercial transactions we have structured with our customers and include the value we extract by optimizing the storage and transportation capacity we own or control as well as revenues for services we deliver.
 
Our asset optimization activities seek to maximize the economic value associated with the storage and transportation capacity we own or control. We attempt to meet this objective by engaging in natural gas storage transactions in which we seek to find and profit from the pricing differences that occur over time. We purchase physical natural gas and then sell financial instruments at advantageous prices to lock in a gross profit margin. We also seek to participate in transactions in which we combine the natural gas commodity and transportation costs to minimize our costs incurred to serve our customers by identifying the lowest cost alternative within the natural gas supplies, transportation and markets to which we have access. Through the use of transportation and storage services and financial instruments, we are able to capture gross profit margin through the arbitrage of pricing differences in various locations and by recognizing pricing differences that occur over time.
 
AEM’s management of natural gas requirements involves the sale of natural gas and the management of storage and transportation supplies under contracts with customers generally having one- to two-year terms. AEM also sells natural gas to some of its industrial customers on a delivered burner tip basis under contract terms ranging from 30 days to two years.
 
Pipeline, Storage and Other Segment Overview
 
Our pipeline, storage and other segment primarily consists of the operations of Atmos Pipeline and Storage, LLC (APS) and Atmos Power Systems, Inc., which are each wholly-owned by AEH.
 
APS owns and operates a 21-mile pipeline located in New Orleans, Louisiana. This pipeline is primarily used to aggregate gas supply for our regulated natural gas distribution division in Louisiana and for AEM. However, it also provides limited third party transportation services. APS also owns or has an interest in underground storage fields in Kentucky and Louisiana. We use these storage facilities to reduce the need to contract for additional pipeline capacity to meet customer demand during peak periods. Finally, beginning in


S-10


Table of Contents

fiscal 2006, APS initiated activities in the natural gas gathering business. As of September 30, 2008, these activities were limited in nature.
 
APS also engages in limited asset optimization activities whereby it seeks to maximize the economic value associated with the storage and transportation capacity it owns or controls. Most of these arrangements are with our regulated affiliates and have been approved by applicable state regulatory commissions. Generally, these arrangements require APS to share with our regulated customers a portion of the profits earned from these arrangements.
 
Through Atmos Power Systems, Inc., we have constructed electric peaking power-generating plants and associated facilities and lease these plants through lease agreements that are accounted for as sales under generally accepted accounting principles.
 
Other Regulation
 
Each of our natural gas distribution divisions is regulated by various state or local public utility authorities. We are also subject to regulation by the United States Department of Transportation with respect to safety requirements in the operation and maintenance of our gas distribution facilities. In addition, our distribution operations are also subject to various state and federal laws regulating environmental matters. From time to time we receive inquiries regarding various environmental matters. We believe that our properties and operations substantially comply with and are operated in substantial conformity with applicable safety and environmental statutes and regulations. There are no administrative or judicial proceedings arising under environmental quality statutes pending or known to be contemplated by governmental agencies which would have a material adverse effect on us or our operations. Our environmental claims have arisen primarily from former manufactured gas plant sites in Tennessee, Iowa and Missouri.
 
FERC allows, pursuant to Section 311 of the Natural Gas Policy Act, gas transportation services through our Atmos Pipeline — Texas assets “on behalf of” interstate pipelines or local distribution companies served by interstate pipelines, without subjecting these assets to the jurisdiction of FERC. FERC also has jurisdiction over some of the types of transactions engaged in by our two nonregulated operations segments, including sales of natural gas in the wholesale gas market and the use and release of interstate pipeline and storage capacity. FERC has adopted rules designed to prevent market power abuse, fraud and market manipulation by companies engaged in the sale, purchase, transportation or storage of natural gas in interstate commerce. We are currently under investigation by FERC for possible violations of its posting and competitive bidding regulations for pre-arranged released firm capacity on interstate natural gas pipelines. We are cooperating with the investigation, are conducting our own investigation of this matter and are taking action to structure current and future transactions to comply with applicable FERC regulations. Although we believe that our reserves are appropriate for the potential penalties, we are currently unable to provide assurance as to the ultimate outcome of this matter.
 
The RRC has issued a final rule requiring the replacement of known compression couplings at pre-bent gas meter risers by November 2009. This rule affects the operations of the Mid-Tex Division but is presently not anticipated to have a significant impact on our West Texas Division. This rule requires us to expend significant amounts of capital in the Mid-Tex Division, but these prudent and mandatory expenditures should be recoverable through our rates.
 
Competition
 
Although our natural gas distribution operations are not currently in significant direct competition with any other distributors of natural gas to residential and commercial customers within our service areas, we do compete with other natural gas suppliers and suppliers of alternative fuels for sales to industrial customers. We compete in all aspects of our business with alternative energy sources, including, in particular, electricity. Electric utilities offer electricity as a rival energy source and compete 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


S-11


Table of Contents

industrial markets. However, higher gas prices, coupled with the electric utilities’ marketing efforts, have increased competition for residential and commercial customers. In addition, AEM competes with other natural gas marketers to provide natural gas management and other related services to customers.
 
Our regulated transmission and storage operations currently face limited competition from other existing intrastate pipelines and gas marketers seeking to provide or arrange transportation, storage and other services for customers.
 
Distribution, Transmission and Related Assets
 
At September 30, 2008, our natural gas distribution segment owned an aggregate of 77,462 miles of underground distribution and transmission mains throughout our gas distribution systems. These mains are located on easements or rights-of-way which generally provide for perpetual use. We maintain our mains through a program of continuous inspection and repair and believe that our system of mains is in good condition. Our regulated transmission and storage segment owned 6,069 miles of gas transmission and gathering lines and our pipeline, storage and other segment owned 114 miles of gas transmission and gathering lines.
 
Storage Assets
 
As of September 30, 2008, we owned underground gas storage facilities in several states to supplement the supply of natural gas in periods of peak demand. The underground gas storage facilities of our natural gas distribution segment had a total usable capacity of 10,343,590 Mcf, with a maximum daily delivery capacity of 232,100 Mcf. The underground gas storage facilities of our regulated transmission and storage segment had a total usable capacity of 39,243,226 Mcf, with a maximum daily delivery capacity of 1,235,000 Mcf. The underground gas storage facilities of our pipeline, storage and other segment had a total usable capacity of 3,931,483 Mcf, with a maximum daily delivery capacity of 127,000 Mcf.
 
Additionally, we contract for storage service in underground storage facilities on many of the interstate pipelines serving us to supplement our proprietary storage capacity. The amount of our contracted storage capacity can vary from time to time. At September 30, 2008, our contracted storage provided us with a maximum storage quantity of 27,371,388 MMBtu, with a maximum daily withdrawal quantity of 778,800 MMBtu, for our natural gas distribution segment, a maximum storage quantity of 7,879,724 MMBtu, with a maximum daily withdrawal quantity of 202,586 MMBtu, for our natural gas marketing segment, and a maximum storage quantity of 1,200,000 MMBtu, with a maximum daily withdrawal quantity of 55,720 MMBtu, for our pipeline, storage and other segment.
 
For more information on our storage assets see “Item 2. Properties” in our annual report on Form 10-K for the fiscal year ended September 30, 2008.

DESCRIPTION OF THE NOTES
 
We have summarized certain provisions of the notes below. The notes constitute a series of the debt securities described in the accompanying prospectus. The notes will be issued under an indenture to be entered into with U.S. Bank National Association, as trustee (the “indenture”).
 
The following description of certain terms of the notes and certain provisions of the indenture in this prospectus supplement supplements the description under “Description of Debt Securities” in the accompanying prospectus and, to the extent it is inconsistent with that description, replaces the description in the accompanying prospectus. This description is only a summary of the material terms and does not purport to be complete. We urge you to read the indenture, a form of which we have filed with the SEC, because it, and not the description below and in the accompanying prospectus, will define your rights as a holder of the notes. We will file the indenture as an exhibit to a current report on Form 8-K at the completion of this offering. You may obtain a copy of the indenture from us without charge. See “Where You Can Find More Information” in the accompanying prospectus.
 
General
 
The notes will be initially limited to $      aggregate principal amount. We may, at any time, without the consent of the holders of these notes, issue additional notes having the same ranking, interest rate, maturity and other terms as the notes. Any such additional notes, together with the notes being offered by this prospectus supplement, will constitute the same series of notes under the indenture.
 
The notes will be unsecured and unsubordinated obligations of Atmos Energy Corporation. Any secured debt that we may have from time to time will have a prior claim with respect to the assets securing that debt. As of December 31, 2008, we had no secured debt outstanding. The notes will rank equally with all of our other existing and future unsubordinated debt. As of December 31, 2008, after giving effect to the redemption of our 4.00% Senior Notes due 2009 on such date with the net proceeds of this offering, we had approximately $   billion of unsecured and unsubordinated debt. Of such $   billion, $1 million represented debt of our subsidiaries. The notes are not guaranteed by, and are not the obligation of, any of our subsidiaries. The notes will not be listed on any securities exchange or included in any automated quotation system.
 
The notes will be issued in book-entry form as one or more global notes registered in the name of the nominee of The Depository Trust Company, or DTC, which will act as a depository, in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof. Beneficial interests in book-entry notes will be shown on, and transfers of the notes will be made only through, records maintained by DTC and its participants.
 
Payment of Principal and Interest
 
The notes will mature on          , 2019 and bear interest at the rate of     % per year.
 
We will pay interest on the notes semi-annually in arrears on          and           of each year they are outstanding, beginning          , 2009. Interest will accrue from          , 2009 or from the most recent interest payment date to which we have paid or provided for the payment of interest to the next interest payment date or the scheduled maturity date, as the case may be. We will pay interest computed on the basis of a 360-day year of twelve 30-day months.
 
We will pay interest on the notes in immediately available funds to the persons in whose names such notes are registered at the close of business on          or           preceding the respective interest payment date. At maturity, we will pay the principal of the notes in immediately available funds upon delivery of such notes to the trustee.

Table of Contents

Optional Redemption
 
Each of the notes offered hereby will be redeemable prior to maturity at our option, at any time in whole or from time to time in part, at a redemption price equal to the greater of:
 
  •  100% of the principal amount of the notes to be redeemed; and
 
  •  as determined by the Quotation Agent (defined below), the sum of the present values of the Remaining Scheduled Payments (defined below) of principal and interest on the notes to be redeemed discounted to the redemption date on a semi-annual basis assuming a 360-day year consisting of twelve 30-day months at the Adjusted Treasury Rate (defined below) plus           basis points;
 
plus, in each case, accrued and unpaid interest on the principal amount of the notes to be redeemed to the redemption date.
 
Definitions.  Following are definitions of the terms used in the optional redemption provisions discussed above.
 
“Adjusted Treasury Rate” means, for any redemption date, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price of the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for that redemption date.
 
“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the remaining term of the notes to be redeemed that would be used, at the time of a selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the notes to be redeemed.
 
“Comparable Treasury Price” means, for any redemption date, the Reference Treasury Dealer Quotation for that redemption date.
 
“Quotation Agent” means the Reference Treasury Dealer appointed by us.
 
“Reference Treasury Dealer” means Banc of America Securities LLC and its successors; provided, however, if Banc of America Securities LLC ceases to be a primary U.S. government securities dealer in New York City, we will replace Banc of America Securities LLC as Reference Treasury Dealer with an entity that is a primary U.S. government securities dealer in New York City.
 
“Reference Treasury Dealer Quotation” means, with respect to any redemption date, the average, as determined by the trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed, in each case, as a percentage of its principal amount) quoted in writing to the trustee by the Reference Treasury Dealer by 5:00 p.m. on the third business day preceding the redemption date.
 
“Remaining Scheduled Payments” means, with respect to each note to be redeemed, the remaining scheduled payments of the principal and interest on such note that would be due after the related redemption date but for such redemption; provided, however, that if such redemption date is not an interest payment date, the amount of the next succeeding scheduled interest payment on such note will be reduced by the amount of interest accrued on such note to such redemption date.
 
In the case of a partial redemption of the notes, the notes to be redeemed shall be selected by DTC. Notice of any redemption will be mailed by first class mail at least 30 days but not more than 60 days before the redemption date to each holder of the notes to be redeemed at its registered address. If any notes are to be redeemed in part only, the notice of redemption will state the portion of the principal amount of notes to be redeemed. A partial redemption will not reduce the portion of any note not being redeemed to a principal amount of less than $2,000. A new note in a principal amount equal to the unredeemed portion of the note will be issued in the name of the holder of the note upon surrender for cancellation of the original note. Unless we default in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the notes or the portions of the notes called for redemption.


S-14


Table of Contents

No Mandatory Redemption
 
We will not be required to redeem the notes before maturity.
 
No Sinking Fund
 
We will not be required to make any sinking fund payments with regard to the notes.
 
Restricted Subsidiaries
 
As of the date of this prospectus supplement, none of our subsidiaries would be considered a Restricted Subsidiary under the terms of the indenture.
 
Governing Law
 
The notes will be governed by and construed in accordance with the laws of the State of New York.
 
Book-Entry Delivery and Settlement
 
We will issue the notes in the form of one or more permanent global securities in definitive, fully registered, book-entry form. The global securities will be deposited with or on behalf of DTC and registered in the name of Cede & Co., as nominee of DTC, or will remain in the custody of the trustee in accordance with arrangements between DTC and the trustee.
 
If you wish to hold securities through the DTC system, you must either be a direct participant in DTC or hold through a direct participant in DTC. Direct participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations that have accounts with DTC. For those holders of notes outside the United States, Euroclear and Clearstream (both described below) participate in DTC through their New York depositaries. Indirect participants are securities brokers and dealers, banks and trust companies that do not have an account with DTC, but that clear through or maintain a custodial relationship with a direct participant. Thus, indirect participants have access to the DTC system through direct participants or through other indirect participants that have access through a direct participant.
 
If you so choose, you may hold your beneficial interests in the global security through Euroclear or Clearstream, or indirectly through organizations that are participants in such systems. Euroclear and Clearstream will hold their participants’ beneficial interests in the global security in their customers’ securities accounts with their depositaries. These depositaries of Euroclear and Clearstream in turn will hold such interests in their customers’ securities accounts with DTC.
 
In sum, you may elect to hold your beneficial interests in the notes:
 
  •  in the United States, through DTC;
 
  •  outside the United States, through Euroclear or Clearstream; or
 
  •  through organizations that participate in such systems.
 
DTC may grant proxies or authorize its participants (or persons holding beneficial interests in the global securities through these participants) to exercise any rights of a holder or take any other actions that a holder is entitled to take under the indenture or the notes. The ability of Euroclear or Clearstream to take actions as a holder of the notes under the indenture will be limited by the ability of their respective depositaries to carry out such actions for them through DTC. Euroclear and Clearstream will take such actions only in accordance with their respective rules and procedures.
 
The information in this section concerning DTC, Euroclear and Clearstream and their book-entry systems has been obtained from sources we believe to be reliable, but we make no representation or warranty with respect to this information. DTC, Euroclear and Clearstream are under no obligation to perform or continue to perform the procedures described below, and they may modify or discontinue them at any time. We and the trustee will not be responsible for DTC’s, Euroclear’s or Clearstream’s performance of their obligations under their rules and procedures, or for the performance by direct or indirect participants of their obligations under the rules and procedures of the clearance systems.

Transfers within DTC, Euroclear and Clearstream will be in accordance with the usual rules and operating procedures of the relevant system. Cross-market transfers between investors who hold or who will hold any notes through DTC and investors who hold or will hold any notes through Euroclear or Clearstream will be effected in DTC through the respective depositaries of Euroclear and Clearstream.
 
The Clearing Systems
 
The Depository Trust Company.  DTC has advised us as follows:
 
  •  DTC 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 under Section 17A of the Securities Exchange Act of 1934;
 
  •  DTC holds securities that its participants deposit with DTC and facilitates the settlement among participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in participants’ accounts, thereby eliminating the need for physical movement of securities certificates;
 
  •  direct participants include securities brokers and dealers (including the underwriters), banks, trust companies, clearing corporations and other organizations;
 
  •  DTC is owned by a number of its direct participants and by the New York Stock Exchange, Inc., the American Stock Exchange, Inc. and the National Association of Securities Dealers, Inc.;
 
  •  access to the DTC system is also available to others such as securities brokers and dealers, banks and trust companies that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly; and
 
  •  the rules applicable to DTC and its participants are on file with the SEC.
 
Euroclear.  Euroclear was created in 1968 to hold securities for its participants and to clear and settle transactions between its participants through simultaneous electronic book-entry delivery against payment, thereby eliminating the need for physical movement of certificates and any risk from lack of simultaneous transfers of securities and cash. Transactions may now be settled in many currencies, including U.S. dollars and euros. Euroclear includes various other services, including securities lending and borrowing, and interfaces with domestic markets in several countries.
 
Euroclear is operated by Euroclear Bank S.A./N.V., which we refer to as the Euroclear Operator, under contract with Euroclear Clearance System, S.C., a Belgian cooperative corporation, or the Cooperative. The Euroclear Operator conducts all operations, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with the Euroclear Operator, not the Cooperative. The Cooperative establishes policy for Euroclear on behalf of Euroclear participants. Euroclear participants include banks (including central banks), the dealer manager, other securities brokers and dealers and other professional financial intermediaries.
 
Indirect access to Euroclear is also available to others that clear through or maintain a custodial relationship with a Euroclear participant, either directly or indirectly. Euroclear is an indirect participant in DTC. As the Euroclear Operator is a Belgian banking corporation, Euroclear is regulated and examined by the Belgian Banking and Finance Commission and the National Bank of Belgium.
 
Securities clearance accounts and cash accounts with the Euroclear Operator are governed by the Terms and Conditions Governing Use of Euroclear and the related Operating Procedures of the Euroclear System, and applicable Belgian law, collectively referred to as the Euroclear Terms and Conditions. The Euroclear 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 clearance accounts. The Euroclear Operator acts under the terms and conditions only on behalf of Euroclear participants and has no record of or relationship with persons holding securities through Euroclear participants.

Distributions with respect to notes held beneficially through Euroclear will be credited to the cash accounts of Euroclear participants in accordance with the Euroclear Terms and Conditions, to the extent received by the depositary for Euroclear.
 
Clearstream.  Clearstream is incorporated under the laws of Luxembourg as a professional depositary. Clearstream holds securities for its participating organizations and facilitates the clearance and settlement of securities transactions between its participants through electronic book-entry changes in accounts of its participants, thereby eliminating the need for physical movement of certificates. Clearstream provides to its participants, among other things, services for safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing.
 
Clearstream interfaces with domestic markets in several countries. Clearstream has established an electronic bridge with Euroclear Bank S.A./N.V., the operator of the Euroclear system, to facilitate settlement of trades between Clearstream and Euroclear. As a professional depositary, Clearstream is subject to regulation by the Luxembourg Commission for the Supervision of the Financial Sector. Clearstream participants are financial institutions around the world, other securities brokers and dealers, banks, trust companies and clearing corporations and certain other organizations. In the United States, Clearstream participants are limited to securities brokers and dealers and banks. Indirect access to Clearstream is also available to others that clear through or maintain a custodial relationship with a Clearstream participant, either directly or indirectly.
 
Distributions with respect to notes held beneficially through Clearstream will be credited to cash accounts of Clearstream participants in accordance with its rules and procedures, to the extent received by the depositary for Clearstream.
 
Initial Settlement
 
We expect that under procedures established by DTC:
 
  •  upon deposit of the global securities with DTC or its custodian, DTC will credit on its internal system the accounts of direct participants designated by the underwriters with portions of the principal amounts of the global securities; and
 
  •  ownership of the securities will be shown on, and the transfer of ownership thereof will be effected only through, records maintained by DTC or its nominee, with respect to interests of direct participants, and the records of direct and indirect participants, with respect to interests of persons other than participants.
 
Euroclear and Clearstream will hold omnibus positions on behalf of their participants through customers’ securities accounts for Euroclear and Clearstream on the books of their respective depositaries, which in turn will hold positions in customers’ securities accounts in the depositaries’ names on the books of DTC.
 
The notes that we issue in this offering will be credited to the securities custody accounts of persons who hold those global securities through DTC (other than through accounts at Euroclear and Clearstream) on the closing date and to persons who hold those global securities through Euroclear or Clearstream on the business day following the closing date.
 
So long as DTC or its nominee is the registered owner of a global security, DTC or that nominee will be considered the sole owner or holder of the notes represented by that global security for all purposes under the indenture and under the notes. Except as provided below, owners of beneficial interests in a global security will not be entitled to have notes represented by that global security registered in their names, will not receive or be entitled to receive physical delivery of certificated notes and will not be considered the owners or holders thereof under the indenture or under the notes for any purpose, including with respect to the giving of any direction, instruction or approval to the trustee. Accordingly, each holder owning a beneficial interest in a global security must rely on the procedures of DTC and, if that holder is not a direct or indirect participant, on the procedures of the participant through which that holder owns its interest, to exercise any rights of a holder of notes under the indenture or the global security.


S-17


Table of Contents

Neither we nor the trustee will have any responsibility or liability for any aspect of the records relating to or payments made on account of the notes by DTC, or for maintaining, supervising or reviewing any records of DTC relating to the notes.
 
Payments on the notes represented by the global securities will be made to DTC or its nominee, as the case may be, as the registered owner thereof. We expect that DTC or its nominee, upon receipt of any payment on the notes represented by a global security, will credit participants’ accounts with payments in amounts proportionate to their respective beneficial interests in the global security as shown in the records of DTC or its nominee. We also expect that payments by participants to owners of beneficial interests in the global security held through such participants will be governed by standing instructions and customary practice as is now the case with securities held for the accounts of customers registered in the names of nominees for such customers. The participants will be responsible for those payments.
 
Payments on the notes represented by the global securities will be made in immediately available funds. Transfers between participants in DTC will be effected in accordance with DTC rules and will be settled in immediately available funds.
 
Transfers Within and Between DTC, Euroclear and Clearstream
 
Trading Between DTC Purchasers and Sellers.  DTC participants will transfer interests in the securities among themselves in the ordinary way according to DTC rules governing global security issues. The laws of some states require certain purchasers of securities to take physical delivery of the securities in definitive form. These laws may impair your ability to transfer beneficial interests in the global security or securities to such purchasers. DTC can act only on behalf of its direct participants, who in turn act on behalf of indirect participants and certain banks. Thus, your ability to pledge a beneficial interest in the global security or securities to persons that do not participate in the DTC system, and to take other actions, may be limited because you will not possess a physical certificate that represents your interest.
 
Trading Between Euroclear and Clearstream Participants.  Participants in Euroclear and Clearstream will transfer interests in the securities among themselves in the ordinary way according to the rules and operating procedures of Euroclear and Clearstream governing conventional eurobonds.
 
Trading Between a DTC Seller and a Euroclear or Clearstream Purchaser.  When the securities are to be transferred from the account of a DTC participant to the account of a Euroclear or Clearstream participant, the purchaser must first send instructions to Euroclear or Clearstream through a participant at least one business day prior to the closing date. Euroclear or Clearstream will then instruct its depositary to receive the securities and make payment for them. On the closing date, the depositary will make payment to the DTC participant’s account and the securities will be credited to the depositary’s account. After settlement has been completed, DTC will credit the securities to Euroclear or Clearstream. Euroclear or Clearstream will credit the securities, in accordance with its usual procedures, to the participant’s account, and the participant will then credit the purchaser’s account. These securities credits will appear the next day (European time) after the closing date. The cash debit from the account of Euroclear or Clearstream will be back-valued to the value date (which will be the preceding day if settlement occurs in New York). If settlement is not completed on the intended value date (i.e., the trade fails), the cash debit will instead be valued at the actual closing date.
 
Participants in Euroclear and Clearstream will need to make funds available to Euroclear or Clearstream to pay for the securities by wire transfer on the value date. The most direct way of doing this is to preposition funds (i.e., have funds in place at Euroclear or Clearstream before the value date), either from cash on hand or existing lines of credit. Under this approach, however, participants may take on credit exposure to Euroclear and Clearstream until the securities are credited to their accounts one day later.
 
As an alternative, if Euroclear or Clearstream has extended a line of credit to a participant, the participant may decide not to preposition funds, but to allow Euroclear or Clearstream to draw on the line of credit to finance settlement for the securities. Under this procedure, Euroclear or Clearstream would charge the participant overdraft charges for one day, assuming that the overdraft would be cleared when the securities were credited to the participant’s account. However, interest on the securities would accrue from the value


S-18


Table of Contents

date. Therefore, in these cases the interest income on securities that the participant earns during that one-day period will substantially reduce or offset the amount of the participant’s overdraft charges. Of course, this result will depend on the cost of funds to (i.e., the interest rate that Euroclear or Clearstream charges) each participant.
 
Since the settlement will occur during New York business hours, a DTC participant selling an interest in the security can use its usual procedures for transferring global securities to the depositaries of Euroclear or Clearstream for the benefit of Euroclear or Clearstream participants. The DTC seller will receive the sale proceeds on the closing date. Thus, to the DTC seller, a cross-market sale will settle no differently than a trade between two DTC participants.
 
Finally, day traders that use Euroclear or Clearstream to purchase interests in the notes from DTC accountholders for delivery to Euroclear or Clearstream participants should note that these trades will automatically fail on the sale side unless affirmative action is taken. At least three techniques should be readily available to eliminate this potential problem:
 
  •  borrowing through Euroclear or Clearstream for one day, until the purchase side of the day trade is reflected in their Euroclear or Clearstream accounts, in accordance with the clearing system’s customary procedures;
 
  •  borrowing the interests in the United States from a DTC accountholder no later than one day prior to settlement, which would give the interests sufficient time to be reflected in their Euroclear or Clearstream account in order to settle the sale side of the trade; or
 
  •  staggering the value date for the buy and sell sides of the trade so that the value date for the purchase from the DTC accountholder is at least one day prior to the value date for the sale to the Euroclear or Clearstream participant.
 
Trading Between a Euroclear or Clearstream Seller and DTC Purchaser.  Due to time zone differences in their favor, Euroclear and Clearstream participants can use their usual procedures to transfer securities through their depositaries to a DTC participant. The seller must first send instructions to Euroclear or Clearstream through a participant at least one business day prior to the closing date. Euroclear or Clearstream will then instruct its depositary to credit the securities to the DTC participant’s account and receive payment. The payment will be credited in the account of the Euroclear or Clearstream participant on the following day, but the receipt of the cash proceeds will be back-valued to the value date (which will be the preceding day if settlement occurs in New York). If settlement is not completed on the intended value date (i.e., the trade fails), the receipt of the cash proceeds will instead be valued at the actual closing date.
 
If the Euroclear or Clearstream participant selling the securities has a line of credit with Euroclear or Clearstream and elects to be in debit for the securities until it receives the sale proceeds in its account, then the back-valuation may substantially reduce or offset any overdraft charges that the participant incurs over that one-day period.
 
Certificated Notes
 
We will issue certificated notes to each person that DTC identifies as the beneficial owner of the notes represented by the global securities upon surrender by DTC of the global securities only if:
 
  •  DTC notifies us that it is no longer willing or able to act as a depository for the global securities, and we have not appointed a successor depository within 60 days of that notice;
 
  •  we determine not to have the notes represented by a global security; or
 
  •  an event of default has occurred and is continuing.
 
Neither we nor the trustee will be liable for any delay by DTC, its nominee or any direct or indirect participant in identifying the beneficial owners of the related notes. We and the trustee may conclusively rely on, and will be protected in relying on, instructions from DTC or its nominee for all purposes, including with respect to the registration and delivery, and the respective principal amounts, of the notes to be issued.

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS
 
Prospective investors should consult their tax advisors with regard to the application of the U.S. federal income tax laws to their particular situations, as well as any tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.
 
The following summary discusses certain material U.S. federal income tax consequences of the acquisition, ownership and disposition of the notes. This discussion is based upon the Internal Revenue Code of 1986, as amended (the “Code”), the applicable proposed or promulgated Treasury regulations, and the applicable judicial and administrative interpretations, all as in effect as of the date hereof and all of which are subject to change, possibly with retroactive effect, and to differing interpretations. This discussion is applicable only to holders of notes who purchase the notes in the initial offering at their original issue price and deals only with the notes held as capital assets for U.S. federal income tax purposes (generally, property held for investment) and not held as part of a straddle, a hedge, a conversion transaction or other integrated investment. This discussion is a summary intended for general information only, and does not address all of the tax consequences that may be relevant to holders of notes in light of their particular circumstances, or to certain types of holders (such as financial institutions, insurance companies, tax-exempt entities, partnerships and other pass-through entities for U.S. federal income tax purposes or investors who hold the notes through such pass-through entities, certain former citizens or residents of the United States, “controlled foreign corporations,” “passive foreign investment companies,” “foreign personal holding companies,” traders in securities that elect to use a mark-to-market method of accounting for their securities holdings, dealers in securities or currencies, or U.S. Holders (as defined below) whose functional currency is not the U.S. dollar). Moreover, this discussion does not describe any state, local or non-U.S. tax implications, or any aspect of U.S. federal tax law other than income taxation. We have not and will not seek any rulings or opinions from the Internal Revenue Service (IRS) or counsel regarding the matters discussed below. There can be no assurances that the IRS will not take positions concerning the tax consequences of the purchase, ownership or disposition of the notes that are different from those discussed below.
 
As used herein, a “U.S. Holder” means a beneficial owner of notes that is, for U.S. federal income tax purposes, (a) a citizen or individual resident of the United States, (b) a corporation or other entity treated as a corporation created or organized in or under the laws of the United States, any State thereof or the District of Columbia, (c) an estate the income of which is subject to U.S. federal income taxation regardless of its source, or (d) a trust, if (1) a court within the United States is able to exercise primary supervision over the trust’s administration and one or more U.S. persons have the authority to control all of its substantial decisions or (2) a valid election to be treated as a U.S. person is in effect under the relevant Treasury regulations with respect to such trust. A “Non-U.S. Holder” means a beneficial owner of any notes that is neither a U.S. Holder nor a partnership for U.S. federal income tax purposes. A Non-U.S. Holder who is an individual present in the United States for 183 days or more in the taxable year of disposition of a note and who is not otherwise a resident of the United States for U.S. federal income tax purposes may be subject to special tax provisions and is urged to consult his or her own tax advisor regarding the U.S. federal income tax consequences of the ownership and disposition of a note. The U.S. federal income tax treatment of partners in partnerships holding notes generally will depend on the activities of the partnership and the status of the partner. Prospective investors that are partnerships (or entities treated as partnerships for U.S. federal income tax purposes) should consult their own tax advisors regarding the U.S. federal income tax consequences to them and their partners of the acquisition, ownership and disposition of the notes.
 
U.S. Federal Income Taxation of U.S. Holders
 
Payments of Interest.  A U.S. Holder must include in gross income, as ordinary interest income, the stated interest on the notes at the time such interest accrues or is received in accordance with the U.S. Holder’s regular method of accounting for U.S. federal income tax purposes.
 
Sale, Retirement or Other Taxable Disposition.  Upon the sale, retirement or other taxable disposition of a note, a U.S. Holder generally will recognize taxable gain or tax loss equal to the difference between (a) the sum of cash plus the fair market value of other property received on the sale, retirement or other taxable


S-20


Table of Contents

disposition (except to the extent such cash or property is attributable to accrued but unpaid interest, which will be treated in the manner described above under “Payments of Interest”) and (b) the U.S. Holder’s adjusted tax basis in the note. A U.S. Holder’s adjusted tax basis in a note generally will equal the amount paid for the note, reduced by any principal payments with respect to the note received by the U.S. Holder. Gain or loss recognized on the sale, retirement or other taxable disposition of a note generally will be capital gain or loss and will be long-term capital gain or loss if, at the time of sale, retirement or other taxable disposition, the note has been held for more than one year. Certain U.S. Holders (including individuals) are currently eligible for preferential rates of U.S. federal income tax in respect of long-term capital gain (which preferential rates are currently scheduled to increase on January 1, 2011). The deductibility of capital losses by U.S. Holders is subject to substantial limitations under the Code.
 
U.S. Federal Income Taxation of Non-U.S. Holders
 
Payments of Interest.  Subject to the discussion of backup withholding below and provided that a Non-U.S. Holder’s income and gains in respect of a note are not effectively connected with the conduct by the Non-U.S. Holder of a U.S. trade or business (or, in the case of an applicable tax treaty, attributable to the Non-U.S. Holder’s permanent establishment in the United States), payments of interest on a note to the Non-U.S. Holder generally will not be subject to U.S. federal income or withholding tax, provided that (a) the Non-U.S. Holder does not own, directly or constructively, 10% or more of the total combined voting power of all classes of our stock entitled to vote within the meaning of section 871(h)(3) of the Code and the Treasury regulations thereunder, (b) the Non-U.S. Holder is not, for U.S. federal income tax purposes, a “controlled foreign corporation” related, directly or constructively, to us through stock ownership, (c) the Non-U.S. Holder is not a bank receiving interest described in section 881(c)(3)(A) of the Code and (d) certain certification requirements (as described below) are met.
 
Under the Code and the applicable Treasury regulations, in order to obtain an exemption from U.S. federal withholding tax, either (a) a Non-U.S. Holder must provide its name and address and certify, under penalties of perjury, that such Non-U.S. Holder is not a U.S. person or (b) a securities clearing organization, bank or other financial institution that holds customers’ securities in the ordinary course of its trade or business (a “Financial Institution”), and that holds the notes on behalf of the Non-U.S. Holder, must certify, under penalties of perjury, that such certificate has been received from such Non-U.S. Holder by such Financial Institution or by another Financial Institution between such Financial Institution and such Non-U.S. Holder and, if required, must furnish the payor with a copy thereof. Generally, the foregoing certification requirement may be met if a Non-U.S. Holder delivers a properly executed IRS Form W-8BEN or substitute Form W-8BEN or the appropriate successor form to the payor. Special rules apply to foreign partnerships, estates and trusts and other intermediaries, and in certain circumstances certifications as to foreign status of partners, trust owners or beneficiaries may have to be provided. In addition, special rules apply to qualified intermediaries that enter into withholding agreements with the IRS.
 
Payments of interest on a note that do not satisfy all of the foregoing requirements generally will be subject to U.S. federal withholding tax at a rate of 30% (or a lower applicable treaty rate, provided certain certification requirements are met). A Non-U.S. Holder generally will be subject to U.S. federal income tax in the same manner as a U.S. Holder with respect to interest on a note if such interest is effectively connected with a U.S. trade or business conducted by the Non-U.S. Holder (or, if an income tax treaty applies, is attributable to a permanent establishment or fixed base maintained by the Non-U.S. Holder in the United States). Under certain circumstances, effectively connected interest income received by a corporate Non-U.S. Holder may be subject to an additional “branch profits tax” at a 30% rate (or a lower applicable treaty rate, provided certain certification requirements are met). Subject to the discussion of backup withholding below, such effectively connected interest income generally will be exempt from U.S. federal withholding tax if a Non-U.S. Holder delivers a properly executed IRS Form W-8ECI to the payor. Non-U.S. Holders should consult their tax advisors about any applicable income tax treaties, which may provide for an exemption from or a lower rate of withholding tax, exemption from or reduction of branch profits tax, or other rules different from those described above.


S-21


Table of Contents

Sale, Retirement or Other Disposition.  Subject to the discussion of backup withholding below, a Non-U.S. Holder generally will not be subject to U.S. federal income or withholding tax on any gain recognized on the sale, retirement or other disposition of the notes so long as the holder provides us or the paying agent with the appropriate certification, unless (a) the Non-U.S. Holder is an individual who is present in the United States for 183 or more days in the taxable year of disposition and certain other conditions are met or (b) the gain is effectively connected with the conduct of a U.S. trade or business by the Non-U.S. Holder (or, if an income tax treaty applies, is attributable to a permanent establishment or fixed base maintained by the Non-U.S. Holder in the United States).
 
Information Reporting and Backup Withholding
 
U.S. Holders.  Generally, information reporting will apply to payments of principal and interest on the notes to a U.S. Holder and to the proceeds of sale or other disposition of the notes, unless the U.S. Holder is an exempt recipient (such as a corporation). Backup withholding generally will apply to such payments (currently at a rate of 28%), if a U.S. Holder fails to provide a correct taxpayer identification number or a certification of exempt status or fails to report in full dividend and interest income. Any amount withheld under the backup withholding rules generally will be allowed as a refund or credit against a U.S. Holder’s U.S. federal income tax liability, provided that the required information is timely furnished to the IRS.
 
Non-U.S. Holders.  Generally, payments of interest on the notes to a Non-U.S. Holder and the amount of any tax withheld from such payments must be reported annually to the IRS and to the Non-U.S. Holder. Copies of these information returns may be made available by the IRS to the tax authorities of the country in which the Non-U.S. Holder is a resident under the provisions of an applicable tax treaty. Under certain circumstances, information reporting also would apply to payments of principal on the notes, and backup withholding of U.S. federal income tax (currently at a rate of 28%) may apply to payments of principal and interest on the notes to a Non-U.S. Holder if the Non-U.S. Holder fails to certify under penalties of perjury that it is not a U.S. person.
 
Payments of the proceeds of the sale or other disposition of the notes by or through a foreign office of a U.S. broker or of a foreign broker with certain specified U.S. connections will be subject to information reporting requirements, but generally not backup withholding, unless the broker has evidence in its records that the payee is not a U.S. person and the broker has no actual knowledge or reason to know to the contrary. Payments of the proceeds of a sale or other disposition of the notes by or through the U.S. office of a broker will be subject to information reporting and backup withholding unless the payee certifies under penalties of perjury that it is not a U.S. person or otherwise establishes an exemption.
 
Any amount withheld under the backup withholding rules generally will be allowed as a refund or credit against a Non-U.S. Holder’s U.S. federal income tax liability, provided that the required information is timely furnished to the IRS.

The underwriting agreement is subject to a number of terms and conditions and provides that the underwriters must buy all of the notes if they buy any of them. The underwriters will sell the notes to the public when and if the underwriters buy the notes from us.
 
The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.
 
The underwriters have advised us that they propose initially to offer the notes to the public at the public offering prices set forth on the cover of this prospectus supplement, and to certain dealers at such price less a concession not in excess of     % of the principal amount of the notes. The underwriters may allow, and such dealers may reallow, a concession not in excess of     % of the principal amount of the notes to certain other dealers. After the public offering of the notes, the public offering price and other selling terms may be changed.
 
We estimate that our share of the total expenses of the offering, excluding the underwriting discount, will be approximately $575,000.
 
We have agreed to indemnify the underwriters against, or contribute to payments that the underwriters may be required to make in respect of, certain liabilities, including liabilities under the Securities Act of 1933.
 
The notes are a new issue of securities with no established trading market. The notes will not be listed on any securities exchange or on any automated dealer quotation system. The underwriters may make a market in the notes after completion of the offering, but will not be obligated to do so and may discontinue any market-making activities at any time without notice. No assurance can be given as to the liquidity of the trading market for the notes or that an active public market for the notes will develop. If an active public market for the notes does not develop, the market price and liquidity of the notes may be adversely affected.
 
In connection with the offering of the notes, certain of the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the notes. Specifically, the underwriters may overallot in connection with the offering, creating a short position. In addition, the underwriters may bid for, and purchase, the notes in the open market to cover short positions or to stabilize the price of the notes. Any of these activities may stabilize or maintain the market price of the notes above independent market levels, but no representation is made hereby of the magnitude of any effect that the transactions described above may have on the market price of the notes. The underwriters will not be required to engage in these activities, and may engage in these activities, and may end any of these activities, at any time without notice.
 
In the ordinary course of business, certain of the underwriters or their affiliates have provided and may in the future provide commercial, financial advisory or investment banking services for us and our subsidiaries for which they have received or will receive customary compensation. Certain of the underwriters are lenders under our revolving credit facilities.

September 30, 2008 have been audited by Ernst & Young LLP, independent registered public accounting firm, as set forth in their reports thereon, included therein, and incorporated herein by reference. Such consolidated financial statements are incorporated herein by reference in reliance upon such reports given on the authority of such firm as experts in accounting and auditing.
 
With respect to the unaudited condensed consolidated interim financial information of Atmos Energy for the three-month periods ended December 31, 2008 and 2007, incorporated herein by reference, Ernst & Young LLP reported that they have applied limited procedures in accordance with professional standards for a review of such information. However, their separate report dated February 3, 2009, included in our quarterly report on Form 10-Q for the three-month period ended December 31, 2008, and incorporated herein by reference, states that they did not audit and they do not express an opinion on that interim financial information. Accordingly, the degree of reliance on their report on such information should be restricted in light of the limited nature of the review procedures applied. Ernst & Young LLP is not subject to the liability provisions of Section 11 of the Securities Act of 1933, as amended, for their report on the unaudited interim financial information because that report is not a “report” or a “part” of the registration statement prepared or certified by Ernst & Young LLP within the meaning of Sections 7 and 11 of the Securities Act of 1933.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS
 
Statements contained or incorporated by reference in this prospectus that are not statements of historical fact are “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended. Forward-looking statements are based on management’s beliefs as well as assumptions made by, and information currently available to, management. Because such statements are based on expectations as to future results and are not statements of fact, actual results may differ materially from those stated. Important factors that could cause future results to differ include, but are not limited to:
 
  •  our ability to continue to access the credit markets to satisfy our liquidity requirements;
 
  •  the impact of economic conditions on our customers;
 
  •  increased costs of providing pension and postretirement health care benefits and increased funding requirements;
 
  •  market risks beyond our control affecting our risk management activities, including market liquidity, commodity price volatility, increasing interest rates and counterparty creditworthiness;
 
  •  regulatory trends and decisions, including the impact of rate proceedings before various state regulatory commissions;
 
  •  increased federal regulatory oversight and potential penalties;
 
  •  the impact of environmental regulations on our business;
 
  •  the concentration of our distribution, pipeline and storage operations in Texas;
 
  •  adverse weather conditions;
 
  •  the effects of inflation and changes in the availability and prices of natural gas;
 
  •  the capital-intensive nature of our natural gas distribution business;
 
  •  increased competition from energy suppliers and alternative forms of energy;
 
  •  the inherent hazards and risks involved in operating our natural gas distribution business;
 
  •  natural disasters, terrorist activities or other events; and
 
  •  other risks and uncertainties discussed in this prospectus, any accompanying prospectus supplement and our other filings with the SEC.
 
All of these factors are difficult to predict and many are beyond our control. Accordingly, while we believe these forward-looking statements to be reasonable, there can be no assurance that they will approximate actual experience or that the expectations derived from them will be realized. When used in our documents or oral presentations, the words “anticipate,” “believe,” “estimate,” “expect,” “forecast,” “goal,” “intend,” “objective,” “plan,” “projection,” “seek,” “strategy” or similar words are intended to identify forward-looking statements. We undertake no obligation to update or revise our forward-looking statements, whether as a result of new information, future events or otherwise.
 
For additional factors you should consider, please see “Risk Factors” on page 1 of this prospectus and “Item 1A. Risk Factors” and “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our annual report on Form 10-K for the fiscal year ended September 30, 2008 and “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our quarterly report on Form 10-Q for the three-month period ended December 31, 2008. See “Incorporation of Certain Documents by Reference,” as well as the applicable prospectus supplement.

RISK FACTORS
 
Investing in our debt securities or our common stock involves risks. Our business is influenced by many factors that are difficult to predict and beyond our control and that involve uncertainties that may materially affect our results of operations, financial condition or cash flows, or the value of these securities. These risks and uncertainties include those described in the risk factor and other sections of the documents that are incorporated by reference in this prospectus. Moreover, risks and uncertainties not presently known to us or currently deemed immaterial by us may also adversely affect our business, results of operations, financial condition or cash flows, or the value of the securities. Subsequent prospectus supplements may contain a discussion of additional risks applicable to an investment in us and the particular type of securities we are offering under the prospectus supplements. You should carefully consider all of the information contained in or incorporated by reference in this prospectus or in the applicable prospectus supplement before you invest in our debt securities or common stock.

Prospectus Supplements
 
This prospectus provides you with a general description of the debt securities and common stock we may offer. Each time we offer securities, we will provide a prospectus supplement that will contain specific information about the terms of the offering. The prospectus supplement may also add to or change information contained in this prospectus. In that case, the prospectus supplement should be read as superseding this prospectus.
 
In each prospectus supplement, which will be attached to the front of this prospectus, we will include, among other things, the following information:
 
  •  the type and amount of securities which we propose to sell;
 
  •  the initial public offering price of the securities;

Fixed charges consist of interest expense, amortization of debt discount, premium and expense, capitalized interest and a portion of lease payments considered to represent an interest factor.
 
DESCRIPTION OF DEBT SECURITIES
 
We may issue debt securities from time to time in one or more distinct series. This section summarizes the material terms of any debt securities that we anticipate will be common to all series. Please note that the terms of any series of debt securities that we may offer may differ significantly from the common terms described in this prospectus. Many of the other terms of any series of debt securities that we offer, and any


2


Table of Contents

differences from the common terms described in this prospectus, will be described in the prospectus supplement for such securities to be attached to the front of this prospectus.
 
As required by U.S. federal law for all bonds and notes of companies that are publicly offered, a document called an “indenture” will govern any debt securities that we issue. An indenture is a contract between us and a financial institution acting as trustee on your behalf. We will enter into an indenture with an institution having corporate trust powers, which will act as trustee (the “indenture”). The indenture will be subject to the Trust Indenture Act of 1939. The trustee under an indenture has the following two main roles:
 
  •  the trustee can enforce your rights against us if we default; there are some limitations on the extent to which the trustee acts on your behalf, which are described later in this prospectus; and
 
  •  the trustee will perform certain administrative duties for us, which include sending you interest payments and notices.
 
As this section is a summary of some of the terms of the debt securities we may offer under this prospectus, it does not describe every aspect of the debt securities. We urge you to read the indenture and the other documents we file with the SEC relating to the debt securities because the indenture for those securities and those other documents, and not this description, will define your rights as a holder of our debt securities. We have filed a form of indenture with the SEC as an exhibit to the registration statement of which this prospectus forms a part, and we will file any such other documents as exhibits to an annual, quarterly or current report that we file with the SEC. The actual indenture we enter into in connection with an offering may differ from the form of indenture we have filed. See “Where You Can Find More Information” for information on how to obtain copies of the indenture and any such other documents. References to the “indenture” mean the indenture that will define your rights as a holder of debt securities. Capitalized terms used in this section and not otherwise defined have the meanings set forth in the form of indenture.
 
General
 
The debt securities will be our unsecured obligations. Senior debt securities will rank equally with all of our other unsecured and unsubordinated indebtedness. Subordinated debt securities will rank junior to our senior indebtedness, including our credit facilities.
 
You should read the prospectus supplement for the following terms of the series of debt securities offered by the prospectus supplement. Our board of directors will establish the following terms before issuance of the series:
 
  •  the title of the debt securities and whether the debt securities will be senior debt securities or subordinated debt securities;
 
  •  the ranking of the debt securities;
 
  •  if the debt securities are subordinated, the terms of subordination;
 
  •  the aggregate principal amount of the debt securities, the percentage of their principal amount at which the debt securities will be issued, and the date or dates when the principal of the debt securities will be payable or how those dates will be determined or extended;
 
  •  the interest rate or rates, which may be fixed or variable, that the debt securities will bear, if any, how the rate or rates will be determined, and the periods when the rate or rates will be in effect;
 
  •  the date or dates from which any interest will accrue or how the date or dates will be determined, the date or dates on which any interest will be payable, whether and the terms under which payment of interest may be deferred, any regular record dates for these payments or how these dates will be determined and the basis on which any interest will be calculated, if other than on the basis of a 360-day year of twelve 30-day months;

Table of Contents

 
  •  the place or places, if any, other than or in addition to New York City, of payment, transfer or exchange of the debt securities, and where notices or demands to or upon us in respect of the debt securities may be served;
 
  •  any optional redemption provisions and any restrictions on the sources of funds for redemption payments, which may benefit the holders of other securities;
 
  •  any sinking fund or other provisions that would obligate us to repurchase or redeem the debt securities;
 
  •  whether the amount of payments of principal of, any premium on, or interest on the debt securities will be determined with reference to an index, formula or other method, which could be based on one or more commodities, equity indices or other indices, and how these amounts will be determined;
 
  •  any modifications, deletions or additions to the events of default or covenants with respect to the debt securities described in this prospectus;
 
  •  if not the principal amount of the debt securities, the portion of the principal amount that will be payable upon acceleration of the maturity of the debt securities or how that portion will be determined;
 
  •  any modifications, deletions or additions to the provisions concerning defeasance and covenant defeasance contained in the indenture that will be applicable to the debt securities;
 
  •  any provisions granting special rights to the holders of the debt securities upon the occurrence of specified events;
 
  •  if other than the trustee, the name of the paying agent, security registrar or transfer agent for the debt securities;
 
  •  if we do not issue the debt securities in book-entry form only to be held by The Depository Trust Company, as depository, whether we will issue the debt securities in certificated form or the identity of any alternative depository;
 
  •  the person to whom any interest in a debt security will be payable, if other than the registered holder at the close of business on the regular record date;
 
  •  the denomination or denominations in which the debt securities will be issued, if other than denominations of $2,000 or any integral multiple of $1,000 in excess thereof;
 
  •  any provisions requiring us to pay Additional Amounts on the debt securities to any holder who is not a United States person in respect of any tax, assessment or governmental charge and, if so, whether we will have the option to redeem the debt securities rather than pay the Additional Amounts;
 
  •  whether the debt securities will be convertible into or exchangeable for other debt securities, common shares or other securities of any kind of ours or another obligor, and, if so, the terms and conditions upon which the debt securities will be so convertible or exchangeable, including the initial conversion or exchange price or rate or the method of calculation, how and when the conversion price or exchange ratio may be adjusted, whether conversion or exchange is mandatory, at the option of the holder or at our option, the conversion or exchange period and any other provision related to the debt securities; and
 
  •  any other material terms of the debt securities or the indenture, which may not be consistent with the terms set forth in this prospectus.
 
For purposes of this prospectus, any reference to the payment of principal of, any premium on, or interest on the debt securities will include Additional Amounts if required by the terms of the debt securities.
 
The indenture will not limit the amount of debt securities that we are authorized to issue from time to time. The indenture will also provide that there may be multiple series of debt securities issued thereunder and more than one trustee thereunder, each for one or more series of debt securities. If a trustee is acting under the indenture with respect to more than one series of debt securities, the debt securities for which it is acting would be treated as if issued under separate indentures. If there is more than one trustee under the indenture,


4


Table of Contents

the powers and trust obligations of each trustee will apply only to the debt securities of the separate series for which it is trustee.
 
We may issue debt securities with terms different from those of debt securities already issued. Without the consent of the holders of the outstanding debt securities, we may reopen a previous issue of a series of debt securities and issue additional debt securities of that series unless the reopening was restricted when we created that series.
 
There is no requirement that we issue debt securities in the future under the indenture, and we may use other indentures or documentation, containing different provisions in connection with future issues of other debt securities.
 
We may issue the debt securities as “original issue discount securities,” which are debt securities, including any zero-coupon debt securities, that are issued and sold at a discount from their stated principal amount. Original issue discount securities provide that, upon acceleration of their maturity, an amount less than their principal amount will become due and payable. We will describe the U.S. federal income tax consequences and other considerations applicable to original issue discount securities in any prospectus supplement relating to them.
 
Holders of Debt Securities
 
Book-Entry Holders.  We will issue debt securities in book-entry form only, unless we specify otherwise in the applicable prospectus supplement. This means the debt securities will be represented by one or more global securities registered in the name of a financial institution that holds them as depository on behalf of other financial institutions that participate in the depository’s book-entry system. These participating institutions, in turn, hold beneficial interests in the debt securities on behalf of themselves or their customers.
 
Under the indenture, we will recognize as a holder only the person in whose name a debt security is registered. Consequently, for debt securities issued in global form, we will recognize only the depository as the holder of the debt securities and we will make all payments on the debt securities to the depository. The depository passes along the payments it receives to its participants, which in turn pass the payments along to their customers who are the beneficial owners. The depository and its participants do so under agreements they have made with one another or with their customers; they are not obligated to do so under the terms of the debt securities. As a result, you will not own the debt securities directly. Instead, you will own beneficial interests in a global security, through a bank, broker or other financial institution that participates in the depository’s book-entry system or holds an interest through a participant. As long as the debt securities are issued in global form, you will be an indirect holder, and not a holder, of the debt securities.
 
Street Name Holders.  In the future we may terminate a global security or issue debt securities initially in non-global form. In these cases, you may choose to hold your debt securities in your own name or in “street name.” Debt securities held in street name would be registered in the name of a bank, broker or other financial institution that you choose, and you would hold only a beneficial interest in those debt securities through an account you maintain at that institution.
 
For debt securities held in street name, we will recognize only the intermediary banks, brokers and other financial institutions in whose names the debt securities are registered as the holders of those debt securities, and we will make all payments on those debt securities to them. These institutions pass along the payments they receive to their customers who are the beneficial owners, but only because they agree to do so in their customer agreements or because they are legally required to do so. If you hold debt securities in street name you will be an indirect holder, and not a holder, of those debt securities.
 
Legal Holders.  Our obligations, as well as the obligations of the trustee and those of any third parties employed by us or the trustee, run only to the legal holders of the debt securities. We do not have obligations to you if you hold beneficial interests in global securities, in street name or by any other indirect means. This will be the case whether you choose to be an indirect holder of a debt security or have no choice because we are issuing the debt securities only in global form.

Table of Contents

For example, once we make a payment or give a notice to the holder, we have no further responsibility for the payment or notice, even if that holder is required, under agreements with depository participants or customers or by law, to pass it along to the indirect holders but does not do so. Similarly, if we want to obtain the approval of the holders for any purpose (for example, to amend the indenture or to relieve us of the consequences of a default or of our obligation to comply with a particular provision of the indenture) we would seek the approval only from the holders, and not the indirect holders, of the debt securities. Whether and how the holders contact the indirect holders is up to the holders.
 
When we refer to you, we mean those who invest in the debt securities being offered by this prospectus, whether they are the holders or only indirect holders of those debt securities. When we refer to your debt securities, we mean the debt securities in which you hold a direct or indirect interest.
 
Special Considerations for Indirect Holders.  If you hold debt securities through a bank, broker or other financial institution, either in book-entry form or in street name, you should check with your own institution to find out:
 
  •  how it handles securities payments and notices;
 
  •  whether it imposes fees or charges;
 
  •  how it would handle a request for the holders’ consent, if ever required;
 
  •  whether and how you can instruct it to send you debt securities registered in your own name so you can be a holder, if that is permitted in the future;
 
  •  how it would exercise rights under the debt securities if there were a default or other event triggering the need for holders to act to protect their interests; and
 
  •  if the debt securities are in book-entry form, how the depository’s rules and procedures will affect these matters.
 
Global Securities
 
What is a Global Security?  We will issue each debt security under the indenture in book-entry form only, unless we specify otherwise in the applicable prospectus supplement. A global security represents one or any other number of individual debt securities. Generally, all debt securities represented by the same global securities will have the same terms. We may, however, issue a global security that represents multiple debt securities that have different terms and are issued at different times. We call this kind of global security a master global security.
 
Each debt security issued in book-entry form will be represented by a global security that we deposit with and register in the name of a financial institution or its nominee that we select. The financial institution that we select for this purpose is called the depository. Unless we specify otherwise in the applicable prospectus supplement, The Depository Trust Company, New York, New York, known as DTC, will be the depository for all debt securities issued in book-entry form.
 
A global security may not be transferred to or registered in the name of anyone other than the depository or its nominee, unless special termination situations arise. We describe those situations below under “Special Situations When a Global Security Will Be Terminated.” As a result of these arrangements, the depository, or its nominee, will be the sole registered owner and holder of all debt securities represented by a global security, and investors will be permitted to own only beneficial interests in a global security. Beneficial interests must be held by means of an account with a broker, bank or other financial institution that in turn has an account with the depository or with another institution that does. Thus, if your security is represented by a global security, you will not be a holder of the debt security, but only an indirect holder of a beneficial interest in the global security.
 
Special Considerations for Global Securities.  We do not recognize an indirect holder as a holder of debt securities and instead deal only with the depository that holds the global security. The account rules of your


6


Table of Contents

financial institution and of the depository, as well as general laws relating to securities transfers, will govern your rights relating to a global security.
 
If we issue debt securities only in the form of a global security, you should be aware of the following:
 
  •  you cannot cause the debt securities to be registered in your name, and cannot obtain non-global certificates for your interest in the debt securities, except in the special situations that we describe below;
 
  •  you will be an indirect holder and must look to your own bank or broker for payments on the debt securities and protection of your legal rights relating to the debt securities, as we describe under “Holders of Debt Securities” above;
 
  •  you may not be able to sell interests in the debt securities to some insurance companies and to other institutions that are required by law to own their securities in non-book-entry form;
 
  •  you may not be able to pledge your interest in a global security in circumstances where certificates representing the debt securities must be delivered to the lender or other beneficiary of the pledge in order for the pledge to be effective;
 
  •  the depository’s policies, which may change from time to time, will govern payments, transfers, exchanges and other matters relating to your interest in a global security. We and the trustee have no responsibility for any aspect of the depository’s actions or for its records of ownership interests in a global security. We and the trustee also do not supervise the depository in any way;
 
  •  DTC requires, and other depositories may require, that those who purchase and sell interests in a global security within its book-entry system use immediately available funds and your broker or bank may require you to do so as well; and
 
  •  financial institutions that participate in the depository’s book-entry system, and through which you hold your interest in a global security, may also have their own policies affecting payments, notices and other matters relating to the debt security. Your chain of ownership may contain more than one financial intermediary. We do not monitor and are not responsible for the actions of any of those intermediaries.
 
Special Situations When a Global Security Will Be Terminated.  In a few special situations described below, a global security will be terminated and interests in it will be exchanged for certificates in non-global form representing the debt securities it represented. After that exchange, you will be able to choose whether to hold the debt securities directly or in street name. You must consult your own bank or broker to find out how to have your interests in a global security transferred on termination to your own name, so that you will be a holder. We have described the rights of holders and street name investors above under “Holders of Debt Securities.”
 
The special situations for termination of a global security are as follows:
 
  •  if the depository notifies us that it is unwilling, unable or no longer qualified to continue as depository for that global security and we do not appoint another institution to act as depository within 60 days;
 
  •  if we notify the trustee that we wish to terminate that global security; or
 
  •  if an event of default has occurred with regard to debt securities represented by that global security and has not been cured or waived. We discuss defaults later under “Events of Default.”
 
If a global security is terminated, only the depository, and not we or the trustee, is responsible for deciding the names of the intermediary banks, brokers and other financial institutions in whose names the debt securities represented by the global security are registered, and, therefore, who will be the holders of those debt securities.

Covenants
 
This section summarizes the material covenants in the indenture. Please refer to the applicable prospectus supplement for information about any changes to our covenants, including any addition or deletion of a covenant, and to the indenture for information on other covenants not described in this prospectus or the applicable prospectus supplement.
 
Limitations on Liens.  We will covenant in the indenture that we will not, and will not permit any of our Restricted Subsidiaries to, create, incur, issue or assume any Indebtedness secured by any Lien on any Principal Property, or on shares of stock or Indebtedness of any Restricted Subsidiary, known as Restricted Securities, without making effective provision for the Outstanding Securities, other than debt securities of any series not entitled to the benefit of this covenant, to be secured by a Lien equally and ratably with, or prior to (or in the case of debt securities of any series that are subordinated in right of payment to the Indebtedness secured by such Lien, by a Lien subordinated to), the Lien securing such Indebtedness for so long as the Indebtedness is so secured, except that the foregoing restriction does not apply to:
 
  •  any Lien existing on the date of the first issuance of debt securities of the relevant series under the indenture or existing on such other date as may be specified in any supplemental indenture, board resolution or officer’s certificate with respect to such series;
 
  •  any Lien on any Principal Property or Restricted Securities of any person existing at the time that person is merged or consolidated with or into us or a Restricted Subsidiary, or this person becomes a Restricted Subsidiary, or arising thereafter otherwise than in connection with the borrowing of money arranged thereafter and pursuant to contractual commitments entered into prior to and not in contemplation of the person’s becoming a Restricted Subsidiary;
 
  •  any Lien on any Principal Property or Restricted Securities existing at the time we or a Restricted Subsidiary acquire the Principal Property or Restricted Securities, whether or not the Lien is assumed by us or the Restricted Subsidiary, provided that this Lien may not extend to any other Principal Property or Restricted Securities of ours or any Restricted Subsidiary;
 
  •  any Lien on any Principal Property, including any improvements on any existing Principal Property, of ours or any Restricted Subsidiary, and any Lien on Restricted Securities of a Restricted Subsidiary that was formed or is held for the purpose of acquiring and holding the Principal Property, in each case to secure all or any part of the cost of acquisition, development, operation, construction, alteration, repair or improvement of all or any part of the Principal Property, or to secure Indebtedness incurred by us or a Restricted Subsidiary for the purpose of financing all or any part of that cost, provided that the Lien is created prior to, at the time of, or within 12 months after the latest of, the acquisition, completion of construction or improvement or commencement of commercial operation of that Principal Property and, provided further, that the Lien may not extend to any other Principal Property of ours or any Restricted Subsidiary, other than any currently unimproved real property on which the Principal Property has been constructed or developed or the improvement is located;
 
  •  any Lien on any Principal Property or Restricted Securities to secure Indebtedness owed to us or to a Restricted Subsidiary;
 
  •  any Lien in favor of a governmental body to secure advances or other payments under any contract or statute or to secure Indebtedness incurred to finance the purchase price or cost of constructing or improving the property subject to the Lien;
 
  •  any Lien created in connection with a project financed with, and created to secure, Non-Recourse Indebtedness;
 
  •  any extension, renewal, substitution or replacement, or successive extensions, renewals, substitutions or replacements, in whole or in part, of any Lien referred to in any of the bullet points above, provided that the Indebtedness secured may not exceed the principal amount of Indebtedness that is secured at the time of the renewal or refunding, plus any premium, cost or expense in connection with such extensions, renewals, substitutions or replacements, and that the renewal or refunding Lien must be

Table of Contents

  limited to all or any part of the same property and improvements, shares of stock or Indebtedness that secured the Lien that was renewed or refunded; or
 
  •  any Lien not permitted above securing Indebtedness that, together with the aggregate outstanding principal amount of other secured Indebtedness that would otherwise be subject to the above restrictions, excluding Indebtedness secured by Liens permitted under the above exceptions, and the Attributable Debt in respect of all Sale and Leaseback Transactions, not including Attributable Debt in respect of any Sale and Leaseback Transactions described in the last two bullet points in the next succeeding paragraph, would not then exceed 15% of our Consolidated Net Tangible Assets.
 
Limitation on Sale and Leaseback Transactions.  We will covenant in the indenture that we will not, and will not permit any Restricted Subsidiary to, enter into any Sale and Leaseback Transaction unless:
 
  •  we or a Restricted Subsidiary would be entitled, without securing the Outstanding Securities of any series, to incur Indebtedness secured by a Lien on the Principal Property that is the subject of the Sale and Leaseback Transaction;
 
  •  the Attributable Debt associated with the Sale and Leaseback Transaction would be in an amount permitted under the last bullet point of the preceding paragraph;
 
  •  the proceeds received in respect of the Principal Property so sold and leased back at the time of entering into the Sale and Leaseback Transaction are to be used for our business and operations or the business and operations of any Subsidiary; or
 
  •  within 12 months after the sale or transfer, an amount equal to the proceeds received in respect of the Principal Property sold and leased back at the time of entering into the Sale and Leaseback Transaction is applied to the prepayment, other than mandatory prepayment, of any Outstanding Securities or Funded Indebtedness owed by us or a Restricted Subsidiary, other than Funded Indebtedness that is held by us or any Restricted Subsidiary or our Funded Indebtedness that is subordinate in right of payment to any Outstanding Securities that are entitled to the benefit of this covenant.
 
Definitions.  Following are definitions of some of the terms used in the covenants described above.
 
“Attributable Debt” means, as to any lease under which a person is at the time liable for rent, at a date that liability is to be determined, the total net amount of rent required to be paid by that person under the lease during the remaining term, excluding amounts required to be paid on account of maintenance and repairs, services, insurance, taxes, assessments, water rates and similar charges and contingent rents, discounted from the respective due dates thereof at the rate of interest (or Yield to Maturity, in the case of original issue discount securities) borne by the then Outstanding Securities, compounded monthly.
 
“Capital Stock” means any and all shares, interests, rights to purchase, warrants, options, participations or other equivalents of or interests, however designated, in stock issued by a corporation.
 
“Consolidated Net Tangible Assets” means the aggregate amount of assets, less applicable reserves and other properly deductible items, after deducting:
 
  •  all current liabilities, excluding any portion thereof constituting Funded Indebtedness; and
 
  •  all goodwill, trade names, trademarks, patents, unamortized debt discount and expense and other like intangibles,
 
all as set forth on our most recent consolidated balance sheet contained in our latest quarterly or annual report filed with the SEC under the Securities Exchange Act of 1934, as amended, and computed in accordance with generally accepted accounting principles.
 
“Funded Indebtedness” means, as applied to any person, all Indebtedness of the person maturing after, or renewable or extendible at the option of the person beyond, 12 months from the date of determination.
 
“Indebtedness” means obligations for money borrowed, evidenced by notes, bonds, debentures or other similar evidences of indebtedness.

Table of Contents

“Lien” means any lien, mortgage, pledge, encumbrance, charge or security interest securing Indebtedness; provided, however, that the following types of transactions will not be considered, for purposes of this definition, to result in a Lien:
 
  •  any acquisition by us or any Restricted Subsidiary of any property or assets subject to any reservation or exception under the terms of which any vendor, lessor or assignor creates, reserves or excepts or has created, reserved or excepted an interest in oil, gas or any other mineral in place or the proceeds of that interest;
 
  •  any conveyance or assignment whereby we or any Restricted Subsidiary conveys or assigns to any person or persons an interest in oil, gas or any other mineral in place or the proceeds of that interest;
 
  •  any Lien upon any property or assets either owned or leased by us or a Restricted Subsidiary or in which we or any Restricted Subsidiary owns an interest that secures for the benefit of the person or persons paying the expenses of developing or conducting operations for the recovery, storage, transportation or sale of the mineral resources of the property or assets, or property or assets with which it is unitized, the payment to the person or persons of our proportionate part or the Restricted Subsidiary’s proportionate part of the development or operating expenses;
 
  •  any lease classified as an operating lease under generally accepted accounting principles;
 
  •  any hedging arrangements entered into in the ordinary course of business, including any obligation to deliver any mineral, commodity or asset; or
 
  •  any guarantees that we make for the repayment of Indebtedness of any Subsidiary or guarantees by any Subsidiary of the repayment of Indebtedness of any entity, including Indebtedness of Atmos Energy Marketing, LLC.
 
“Non-Recourse Indebtedness” means, at any time, Indebtedness incurred after the date of the indenture by us or a Restricted Subsidiary in connection with the acquisition of property or assets by us or a Restricted Subsidiary or the financing of the construction of or improvements on property, whenever acquired, provided that, under the terms of this Indebtedness and under applicable law, the recourse at the time and thereafter of the lenders with respect to this Indebtedness is limited to the property or assets so acquired, or the construction or improvements, including Indebtedness as to which a performance or completion guarantee or similar undertaking was initially applicable to the Indebtedness or the related property or assets if the guarantee or similar undertaking has been satisfied and is no longer in effect. Indebtedness which is otherwise Non-Recourse Indebtedness will not lose its character as Non-Recourse Indebtedness because there is recourse to us, any subsidiary of ours or any other person for (a) environmental or tax warranties and indemnities and such other representations, warranties, covenants and indemnities as are customarily required in such transactions or (b) indemnities for and liabilities arising from fraud, misrepresentation, misapplication or non-payment of rents, profits, insurance and condemnation proceeds and other sums actually received from secured assets to be paid to the lender, waste and mechanics’ liens or similar matters.
 
“Principal Property” means any natural gas distribution property located in the United States, except any property that in the opinion of our board of directors is not of material importance to the total business conducted by us and of our consolidated Subsidiaries.
 
“Restricted Subsidiary” means any Subsidiary the amount of Consolidated Net Tangible Assets of which constitutes more than 10% of the aggregate amount of Consolidated Net Tangible Assets of us and our Subsidiaries.
 
“Sale and Leaseback Transaction” means any arrangement with any person in which we or any Restricted Subsidiary leases any Principal Property that has been or is to be sold or transferred by us or the Restricted Subsidiary to that person, other than any such arrangement involving:
 
  •  a lease for a term, including renewals at the option of the lessee, of not more than three years or classified as an operating lease under generally accepted accounting principles;
 
  •  leases between us and a Restricted Subsidiary or between Restricted Subsidiaries; and


10


Table of Contents

 
  •  leases of a Principal Property executed by the time of, or within 12 months after the latest of, the acquisition, the completion of construction or improvement, or the commencement of commercial operation, of the Principal Property, whichever is later.
 
“Subsidiary” of ours means:
 
  •  a corporation, a majority of whose Capital Stock with rights, under ordinary circumstances, to elect directors is owned, directly or indirectly, at the date of determination, by us, by one or more of our Subsidiaries or by us and one or more of our Subsidiaries; or
 
  •  any other person, other than a corporation, in which at the date of determination we, one or more of our Subsidiaries or we and one or more of our Subsidiaries, directly or indirectly, have at least a majority ownership and power to direct the policies, management and affairs of that person.
 
Consolidation, Merger or Sale of Assets.  Under the terms of the indenture, we will be generally permitted to consolidate with or merge into another entity. We will also be permitted to sell or transfer our assets substantially as an entirety to another entity. However, we may not take any of these actions unless all of the following conditions are met:
 
  •  the resulting entity must agree to be legally responsible for all our obligations relating to the debt securities and the indenture;
 
  •  the transaction must not cause a default or an Event of Default, as described below;
 
  •  the resulting entity must be organized under the laws of the United States or one of the states or the District of Columbia; and
 
  •  we must deliver an officers’ certificate and legal opinion to the trustee with respect to the transaction.
 
In the event that we engage in one of these transactions and comply with the conditions listed above, we would be discharged from all our obligations and covenants under the indenture and all obligations under the Outstanding Securities, with the successor corporation or person succeeding to our obligations and covenants.
 
In the event that we engage in one of these transactions, the indenture provides that, if any Principal Property or Restricted Securities would thereupon become subject to any Lien securing the Indebtedness, the debt securities, other than debt securities not entitled to the benefits of specified covenants, must be secured, as to such Principal Property or Restricted Securities, equally and ratably with (or prior to or, in the case of debt securities that are subordinated in right of payment to the Indebtedness secured by such Lien or in the case of other Indebtedness of ours that is subordinated to the debt securities, on a subordinated basis to such Lien securing) the Indebtedness or obligations that upon the occurrence of such transaction would become secured by the Lien, unless the Lien could be created under the indenture without equally and ratably securing the debt securities (or, in the case of debt securities that are subordinated in right of payment to the Indebtedness secured by such Lien, on a subordinated basis to such Lien).
 
Modification or Waiver
 
There are two types of changes that we can make to the indenture and the debt securities.
 
Changes Requiring Approval.  With the approval of the holders of at least a majority in principal amount of all outstanding debt securities of each series affected (including any such approvals obtained in connection with a tender or exchange offer for outstanding debt securities), we may make any changes, additions or deletions to any provisions of the indenture applicable to the affected series, or modify the rights of the holders of the debt securities of the affected series. However, without the consent of each holder affected, we cannot:
 
  •  change the stated maturity of the principal of, any premium on, or the interest on a debt security;
 
  •  reduce the principal amount, any premium on, or the rate of interest on a debt security;
 
  •  change any of our obligations to pay Additional Amounts;


11


Table of Contents

 
  •  reduce the amount payable upon acceleration of maturity following the default of a debt security whose principal amount payable at stated maturity may be more or less than its principal face amount at original issuance or an original issue discount security;
 
  •  adversely affect any right of repayment at the holder’s option;
 
  •  change the place of payment of a debt security;
 
  •  impair the holder’s right to sue for payment;
 
  •  adversely affect any right to convert or exchange a debt security;
 
  •  reduce the percentage of holders of debt securities whose consent is needed to modify or amend the indenture; or
 
  •  modify certain provisions of the indenture dealing with suits for enforcement of payment by the trustee or modification and waiver, except to increase any percentage of consents required to amend the indenture or for any waiver, or to modify the provisions of the indenture dealing with the unconditional right of the holders of the debt securities to receive principal, premium, if any, and interest.
 
Changes Not Requiring Approval.  The second type of change does not require any vote by the holders of the debt securities. This type is limited to clarifications and certain other changes that would not adversely affect holders of the outstanding debt securities in any material respect. Additionally, we do not need any approval to make any change that affects only debt securities to be issued under the indenture after the changes take effect.
 
Further Details Concerning Voting.  When taking a vote, we will use the following rules to decide how much principal amount to attribute to a debt security:
 
  •  for original issue discount securities, we will use the principal amount that would be due and payable on the voting date if the maturity of the debt securities were accelerated to that date because of a default; and
 
  •  for debt securities whose principal amount is not known (for example, because it is based on an index) we will use a special rule for that debt security described in the applicable prospectus supplement.
 
Debt securities will not be considered outstanding, and therefore not eligible to vote, if we have deposited or set aside in trust money for their payment or redemption. Debt securities will also not be eligible to vote if they have been fully defeased as described later under “Defeasance and Covenant Defeasance.”
 
Book-entry and other indirect holders should consult their banks or brokers for information on how approval may be granted or denied if we seek to change the indenture or the debt securities or request a waiver.
 
Events of Default
 
Holders of debt securities will have special rights if an Event of Default occurs as to the debt securities of their series that is not cured, as described later in this subsection. Please refer to the applicable prospectus supplement for information about any changes to the Events of Default, including any addition of a provision providing event risk or similar protection.
 
What is an Event of Default?  The term “Event of Default” as to the debt securities of a series means any of the following:
 
  •  we do not pay interest on a debt security of the series within 30 days of its due date;
 
  •  we do not pay the principal of or any premium, if any, on a debt security of the series on its due date;
 
  •  we do not deposit any sinking fund payment when and as due by the terms of any debt securities requiring such payment;


12


Table of Contents

 
  •  we remain in breach of a covenant or agreement in the indenture, other than a covenant or agreement not for the benefit of the series, for 60 days after we receive written notice stating that we are in breach from the trustee or the holders of at least 25 percent of the principal amount of the debt securities of the series;
 
  •  we or a Restricted Subsidiary is in default under any matured or accelerated agreement or instrument under which we have outstanding Indebtedness for borrowed money or guarantees, which individually is in excess of $25,000,000, and we have not cured any acceleration within 30 days after we receive notice of this default from the trustee or the holders of at least 25 percent of the principal amount of the debt securities of the series, unless prior to the entry of judgment for the trustee, we or the Restricted Subsidiary remedy the default or the default is waived by the holders of the indebtedness;
 
  •  we file for bankruptcy or other events of bankruptcy, insolvency or reorganization occur; or
 
  •  any other Event of Default provided for the benefit of debt securities of the series.
 
An Event of Default for a particular series of debt securities will not necessarily constitute an Event of Default for any other series of debt securities issued under the indenture.
 
The trustee may withhold notice to the holders of debt securities of a particular series of any default if it considers its withholding of notice to be in the interest of the holders of that series, except that the trustee may not withhold notice of a default in the payment of the principal of, any premium on, or the interest on the debt securities or in the payment of any sinking fund installment with respect to the debt securities.
 
Remedies if an Event of Default Occurs.  If an event of default has occurred and is continuing, the trustee or the holders of at least 25 percent in principal amount of the debt securities of the affected series may declare the entire principal amount and all accrued interest of all the debt securities of that series to be due and immediately payable by notifying us, and the trustee, if the holders give notice, in writing. This is called a declaration of acceleration of maturity.
 
If the maturity of any series of debt securities is accelerated and a judgment for payment has not yet been obtained, the holders of a majority in principal amount of the debt securities of that series may cancel the acceleration if all events of default other than the non-payment of principal or interest on the debt securities of that series that have become due solely by a declaration of acceleration are cured or waived, and we deposit with the trustee a sufficient sum of money to pay:
 
  •  all overdue interest on outstanding debt securities of that series;
 
  •  all unpaid principal and any premium, if any, of any outstanding debt securities of that series that has become due otherwise than by a declaration of acceleration, and interest on the unpaid principal and any premium, if any;
 
  •  all interest on the overdue interest; and
 
  •  all amounts paid or advanced by the trustee for that series and reasonable compensation of the trustee.
 
Except in cases of default, where the trustee has some special duties, the trustee is not required to take any action under the indenture at the request of any holders unless the holders offer the trustee reasonable protection from expenses and liability. This is called an indemnity. If reasonable indemnity is provided, the holders of a majority in principal amount of the outstanding debt securities of the relevant series may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the trustee. The trustee may refuse to follow those directions if the directions conflict with any law or the indenture or expose the trustee to personal liability. No delay or omission in exercising any right or remedy will be treated as a waiver of that right, remedy or Event of Default.


13


Table of Contents

Before a holder is allowed to bypass the trustee and bring his or her own lawsuit or other formal legal action or take other steps to enforce his or her rights or protect his or her interest relating to the debt securities, the following must occur:
 
  •  the holder must give the trustee written notice that an Event of Default has occurred and remains uncured;
 
  •  the holders of at least 25 percent in principal amount of all outstanding debt securities of the relevant series must make a written request that the trustee take action because of the default and must offer reasonable indemnity to the trustee against the cost and other liabilities of taking that action;
 
  •  the trustee must not have instituted a proceeding for 60 days after receipt of the above notice and offer of indemnity; and
 
  •  the holders of a majority in principal amount of the debt securities must not have given the trustee a direction inconsistent with the above notice during the 60-day period.
 
However, a holder is entitled at any time to bring a lawsuit for the payment of money due on his or her debt securities on or after the due date without complying with the foregoing.
 
Holders of a majority in principal amount of the debt securities of the affected series may waive any past defaults other than the following:
 
  •  the payment of principal, any premium, or interest on any debt security; or
 
  •  in respect of a covenant that under the indenture cannot be modified or amended without the consent of each holder affected.
 
Each year, we will furnish the trustee with a written statement of two of our officers certifying that, to their knowledge, we are in compliance with the indenture and the debt securities, or else specifying any default.
 
Book-entry and other indirect holders should consult their banks or brokers for information on how to give notice or direction to or make a request of the trustee and how to declare or cancel an acceleration.
 
Defeasance and Covenant Defeasance
 
Unless we provide otherwise in the applicable prospectus supplement, the provisions for full defeasance and covenant defeasance described below apply to each series of debt securities. In general, we expect these provisions to apply to each debt security that is not a floating rate or indexed debt security.
 
Full Defeasance.  If there is a change in U.S. federal tax law, as described below, we can legally release ourselves from all payment and other obligations on the debt securities, called “full defeasance,” if we put in place the following arrangements for you to be repaid:
 
  •  we must deposit in trust for the benefit of all holders of the debt securities a combination of money and obligations issued or guaranteed by the U.S. government that will generate enough cash to make interest, principal and any other payments on the debt securities on their various due dates; and
 
  •  we must deliver to the trustee a legal opinion confirming that there has been a change in current federal tax law or an IRS ruling that lets us make the above deposit without causing you to be taxed on the debt securities any differently than if we did not make the deposit and just repaid the debt securities ourselves at maturity.
 
If we ever did accomplish defeasance, as described above, you would have to rely solely on the trust deposit for repayment of the debt securities. You could not look to us for repayment in the event of any shortfall. Conversely, the trust deposit would most likely be protected from claims of our lenders and other creditors if we ever become bankrupt or insolvent. If we accomplish a defeasance, we would retain only the obligations to register the transfer or exchange of the debt securities, to maintain an office or agency in respect of the debt securities and to hold moneys for payment in trust.


14


Table of Contents

Covenant Defeasance.  Under current federal tax law, we can make the same type of deposit described above and be released from any restrictive covenants in the indenture. This is called “covenant defeasance.” In that event, you would lose the protection of any such covenants but would gain the protection of having money and obligations issued or guaranteed by the U.S. government set aside in trust to repay the debt securities. In order to achieve covenant defeasance, we must do the following:
 
  •  deposit in trust for your benefit and the benefit of all other direct holders of the debt securities a combination of money and obligations issued or guaranteed by the U.S. government that will generate enough cash to make interest, principal and any other payments on the debt securities on their various due dates; and
 
  •  deliver to the trustee a legal opinion of our counsel confirming that, under current federal income tax law, we may make the deposit described above without causing you to be taxed on the debt securities any differently than if we did not make the deposit and just repaid the debt securities ourselves at maturity.
 
If we accomplish covenant defeasance, you can still look to us for repayment of the debt securities if there were a shortfall in the trust deposit or the trustee is prevented from making payment. In fact, if one of the remaining Events of Default occurred, such as our bankruptcy, and the debt securities became immediately due and payable, there may be a shortfall. Depending on the event causing the default, you may not be able to obtain payment of the shortfall.
 
Debt Securities Issued in Non-Global Form
 
If any debt securities cease to be issued in global form, they will be issued:
 
  •  only in fully registered form;
 
  •  without interest coupons; and
 
  •  unless we indicate otherwise in the prospectus supplement, in denominations of $2,000 and amounts that are integral multiples of $1,000 in excess thereof.
 
Holders may exchange their debt securities that are not in global form for debt securities of smaller denominations or combined into fewer debt securities of larger denominations, as long as the total principal amount is not changed.
 
Holders may exchange or transfer their debt securities at the office of the trustee. We may appoint the trustee to act as our agent for registering debt securities in the names of holders transferring debt securities, or we may appoint another entity to perform these functions or perform them ourselves.
 
Holders will not be required to pay a service charge to transfer or exchange their debt securities, but they may be required to pay for any tax or other governmental charge associated with the transfer or exchange. The transfer or exchange will be made only if our transfer agent is satisfied with the holder’s proof of legal ownership.
 
If we have designated additional transfer agents for a holder’s debt security, they will be named in the applicable prospectus supplement. We may appoint additional transfer agents or cancel the appointment of any particular transfer agent. We may also approve a change in the office through which any transfer agent acts.
 
If any debt securities are redeemable and we redeem less than all those debt securities, we may stop the transfer or exchange of those debt securities during the period beginning 15 days before the day we mail the notice of redemption and ending on the day of that mailing, in order to freeze the list of holders to prepare the mailing. We may also refuse to register transfers or exchanges of any debt securities selected for redemption, except that we will continue to permit transfers and exchanges of the unredeemed portion of any debt security that will be partially redeemed.
 
If a debt security is issued as a global security, only the depository will be entitled to transfer and exchange the debt security as described in this section, since it will be the sole holder of the debt security.

Payment Mechanics
 
Who Receives Payment?  If interest is due on a debt security on an interest payment date, we will pay the interest to the person or entity in whose name the debt security is registered at the close of business on the regular record date, discussed below, relating to the interest payment date. If interest is due at maturity but on a day that is not an interest payment date, we will pay the interest to the person or entity entitled to receive the principal of the debt security. If principal or another amount besides interest is due on a debt security at maturity, we will pay the amount to the holder of the debt security against surrender of the debt security at a proper place of payment, or, in the case of a global security, in accordance with the applicable policies of the depository.
 
Payments on Global Securities.  We will make payments on a global security in accordance with the applicable policies of the depository as in effect from time to time. Under those policies, we will pay directly to the depository, or its nominee, and not to any indirect holders who own beneficial interests in the global security. An indirect holder’s right to those payments will be governed by the rules and practices of the depository and its participants, as described above under “What is a Global Security?”.
 
Payments on Non-Global Securities.  For a debt security in non-global form, we will pay interest that is due on an interest payment date by check mailed on the interest payment date to the holder at his or her address shown on the trustee’s records as of the close of business on the regular record date. We will make all other payments by check, at the paying agent described below, against surrender of the debt security. We will make all payments by check in next-day funds; for example, funds that become available on the day after the check is cashed.
 
Alternatively, if a non-global security has a face amount of at least $1,000,000 and the holder asks us to do so, we will pay any amount that becomes due on the debt security by wire transfer of immediately available funds to an account at a bank in New York City on the due date. To request wire payment, the holder must give the paying agent appropriate transfer instructions at least five business days before the requested wire payment is due. In the case of any interest payment due on an interest payment date, the instructions must be given by the person who is the holder on the relevant regular record date. In the case of any other payment, we will make payment only after the debt security is surrendered to the paying agent. Any wire instructions, once properly given, will remain in effect unless and until new instructions are given in the manner described above.
 
Regular Record Dates.  We will pay interest to the holders listed in the trustee’s records as the owners of the debt securities at the close of business on a particular day in advance of each interest payment date. We will pay interest to these holders if they are listed as the owner even if they no longer own the debt security on the interest payment date. That particular day, usually about two weeks in advance of the interest payment date, is called the “regular record date” and will be identified in the prospectus supplement.
 
Payment When Offices Are Closed.  If any payment is due on a debt security on a day that is not a business day, we will make the payment on the next business day. Payments postponed to the next business day in this situation will be treated under the indenture as if they were made on the original due date. A postponement of this kind will not result in a default under any debt security or the indenture, and no interest will accrue on the postponed amount from the original due date to the next business day.
 
Paying Agents.  We may appoint one or more financial institutions to act as our paying agents, at whose designated offices debt securities in non-global form may be surrendered for payment at their maturity. We call each of those offices a paying agent. We may add, replace or terminate paying agents from time to time. We may also choose to act as our own paying agent. Initially, we have appointed the trustee, at its corporate trust office in New York City, as the paying agent. We must notify you of changes in the paying agents.
 
Book-entry and other indirect holders should consult their banks or brokers for information on how they will receive payments on their debt securities.

U.S. Bank National Association is the trustee under the indenture for our debt securities. We will identify any other entity acting as the trustee for a series of debt securities that we may offer in the prospectus supplement for the offering of such debt securities.
 
The trustee may resign or be removed with respect to one or more series of debt securities and a successor trustee may be appointed to act with respect to these series.
 
DESCRIPTION OF COMMON STOCK
 
General
 
Our authorized capital stock consists of 200,000,000 shares of common stock, of which 91,914,143 shares were outstanding on March 17, 2009. Each of our shares of common stock is entitled to one vote on all matters voted upon by shareholders. Our shareholders do not have cumulative voting rights. Our issued and outstanding shares of common stock are fully paid and nonassessable. There are no redemption or sinking fund provisions applicable to the shares of our common stock, and such shares are not entitled to any preemptive rights. Since we are incorporated in both Texas and Virginia, we must comply with the laws of both states when issuing shares of our common stock.
 
Holders of our shares of common stock are entitled to receive such dividends as may be declared from time to time by our board of directors from our assets legally available for the payment of dividends and, upon our liquidation, a pro rata share of all of our assets available for distribution to our shareholders.
 
American Stock Transfer & Trust Company is the registrar and transfer agent for our common stock.
 
Charter and Bylaws Provisions
 
Some provisions of our articles of incorporation and bylaws may be deemed to have an “anti-takeover” effect. The following description of these provisions is only a summary, and we refer you to our articles of incorporation and bylaws for more information. Our articles of incorporation and bylaws are included as exhibits to our annual reports on Form 10-K filed with the SEC. See “Where You Can Find More Information.”
 
Classification of the Board.  Our board of directors is divided into three classes, each of which consists, as nearly as may be possible, of one-third of the total number of directors constituting the entire board. There are currently 13 directors serving on the board. Each class of directors serves a three-year term. At each annual meeting of our shareholders, successors to the class of directors whose term expires at the annual meeting are elected for three-year terms. Our articles of incorporation prohibit cumulative voting. In general, in the absence of cumulative voting, one or more persons who hold a majority of our outstanding shares can elect all of the directors who are subject to election at any meeting of shareholders.
 
The classification of directors could have the effect of making it more difficult for shareholders, including those holding a majority of the outstanding shares, to force an immediate change in the composition of the board. Two shareholder meetings, instead of one, generally will be required to effect a change in the control of our board.
 
Removal of Directors.  Our articles of incorporation and bylaws also provide that our directors may be removed only for cause and upon the affirmative vote of the holders of at least 75 percent of the shares then entitled to vote at an election of directors.
 
Fair Price Provisions.  Article VII of our articles of incorporation provides certain “Fair Price Provisions” for our shareholders. Under Article VII, a merger, consolidation, sale of assets, share exchange, recapitalization or other similar transaction, between us or a company controlled by or under common control with us and any individual, corporation or other entity which owns or controls 10 percent or more of our voting capital stock, would be required to satisfy the condition that the aggregate consideration per share to be

received in the transaction for each class of our voting capital stock be at least equal to the highest per share price, or equivalent price for any different classes or series of stock, paid by the 10 percent shareholder in acquiring any of its holdings of our stock. If a proposed transaction with a 10 percent shareholder does not meet this condition, then the transaction must be approved by the holders of at least 75 percent of the outstanding shares of voting capital stock held by our shareholders other than the 10 percent shareholder, unless a majority of the directors who were members of our board immediately prior to the time the 10 percent shareholder involved in the proposed transaction became a 10 percent shareholder have either:
 
  •  expressly approved in advance the acquisition of the outstanding shares of our voting capital stock that caused the 10 percent shareholder to become a 10 percent shareholder; or
 
  •  approved the transaction either in advance of or subsequent to the 10 percent shareholder becoming a 10 percent shareholder.
 
The provisions of Article VII may not be amended, altered, changed, or repealed except by the affirmative vote of at least 75 percent of the votes entitled to be cast thereon at a meeting of our shareholders duly called for consideration of such amendment, alteration, change, or repeal. In addition, if there is a 10 percent shareholder, such action must also be approved by the affirmative vote of at least 75 percent of the outstanding shares of our voting capital stock held by the shareholders other than the 10 percent shareholder.
 
Shareholder Proposals and Director Nominations.  Our shareholders can submit shareholder proposals and nominate candidates for the board of directors if the shareholders follow the advance notice procedures described in our bylaws.
 
Shareholder proposals (other than those sought to be included in our proxy statement) must be submitted to our corporate secretary at least 60 days, but not more than 85 days, before the annual meeting; provided, however, that if less than 75 days’ notice or prior public disclosure of the date of the annual meeting is given or made to shareholders, notice by the shareholder to be timely must be received by our corporate secretary no later than the close of business on the 25th day following the day on which such notice of the date of the annual meeting was provided or such public disclosure was made. The notice must include a description of the proposal, the shareholder’s name and address and the number of shares held, and all other information which would be required to be included in a proxy statement filed with the SEC if the shareholder were a participant in a solicitation subject to the SEC’s proxy rules. To be included in our proxy statement for an annual meeting, our corporate secretary must receive the proposal at least 120 days prior to the anniversary of the date we mailed the proxy statement for the prior year’s annual meeting.
 
To nominate directors, shareholders must submit a written notice to our corporate secretary at least 60 days, but not more than 85 days, before a scheduled meeting; provided, however, that if less than 75 days’ notice or prior public disclosure of the date of the annual meeting is given or made to shareholders, such nomination shall have been received by our corporate secretary no later than the close of business on the 25th day following the day on which such notice of the date of the annual meeting was mailed or such public disclosure was made. The notice must include the name and address of the shareholder and of the shareholder’s nominee, the number of shares held by the shareholder, a representation that the shareholder is a holder of record of common stock entitled to vote at the meeting, and that the shareholder intends to appear in person or by proxy to nominate the persons specified in the notice, a description of any arrangements between the shareholder and the shareholder’s nominee, information about the shareholder’s nominee required by the SEC and the written consent of the shareholder’s nominee to serve as a director.
 
Shareholder proposals and director nominations that are late or that do not include all required information may be rejected. This could prevent shareholders from bringing certain matters before an annual or special meeting or making nominations for directors.

PLAN OF DISTRIBUTION
 
We may sell the securities offered by this prospectus and a prospectus supplement as follows:
 
  •  through agents;
 
  •  to or through underwriters;
 
  •  through dealers;
 
  •  directly by us to purchasers; or
 
  •  through a combination of any such methods of sale.
 
We, directly or through agents or dealers, may sell, and the underwriters may resell, the securities in one or more transactions, including:
 
  •  transactions on the New York Stock Exchange or any other organized market where the securities may be traded;
 
  •  in the over-the-counter market;
 
  •  in negotiated transactions; or
 
  •  through a combination of any such methods of sale.
 
The securities may be sold at a fixed price or prices which may be changed, at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices.
 
Agents designated by us from time to time may solicit offers to purchase the securities. We will name any such agent involved in the offer or sale of the securities and set forth any commissions payable by us to such agent in a prospectus supplement relating to any such offer and sale of securities. Unless otherwise indicated in the prospectus supplement, any such agent will be acting on a best efforts basis for the period of its appointment. Any such agent may be deemed to be an underwriter of the securities, as that term is defined in the Securities Act.
 
If underwriters are used in the sale of securities, securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions. Securities may be offered to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. If an underwriter or underwriters are used in the sale of securities, we will execute an underwriting agreement with such underwriter or underwriters at the time an agreement for such sale is reached. We will set forth in the prospectus supplement the names of the specific managing underwriter or underwriters, as well as any other underwriters, and the terms of the transactions, including compensation of the underwriters and dealers. Such compensation may be in the form of discounts, concessions or commissions. Underwriters and others participating in any offering of securities may engage in transactions that stabilize, maintain or otherwise affect the price of such securities. We will describe any such activities in the prospectus supplement.
 
We may elect to list any class or series of securities on any exchange, but we are not currently obligated to do so. It is possible that one or more underwriters, if any, may make a market in a class or series of securities, but the underwriters will not be obligated to do so and may discontinue any market making at any time without notice. We cannot give any assurance as to the liquidity of the trading market for any of the securities we may offer.
 
If a dealer is used in the sale of the securities, we or an underwriter will sell such securities to the dealer, as principal. The dealer may then resell such securities to the public at varying prices to be determined by such dealer at the time of resale. The prospectus supplement will set forth the name of the dealer and the terms of the transactions.
 
We may directly solicit offers to purchase the securities, and we may sell directly to institutional investors or others. These persons may be deemed to be underwriters within the meaning of the Securities Act with respect to any resale of the securities. The prospectus supplement will describe the terms of any such sales, including the terms of any bidding, auction or other process, if used.

Agents, underwriters and dealers may be entitled under agreements which may be entered into with us to indemnification by us against specified liabilities, including liabilities under the Securities Act, or to contribution by us to payments they may be required to make in respect of such liabilities. The prospectus supplement will describe the terms and conditions of such indemnification or contribution. Some of the agents, underwriters or dealers, or their affiliates, may engage in transactions with or perform services for us and our subsidiaries in the ordinary course of their business.
 
LEGAL MATTERS
 
Gibson, Dunn & Crutcher LLP, Dallas, Texas, and Hunton & Williams LLP, Richmond, Virginia, have each rendered an opinion with respect to the validity of the securities that may be offered under this prospectus. We filed these opinions as exhibits to the registration statement of which this prospectus is a part. If counsel for any underwriters passes on legal matters in connection with an offering made under this prospectus, we will name that counsel in the prospectus supplement relating to that offering.
 
EXPERTS
 
The consolidated financial statements of Atmos Energy appearing in Atmos Energy Corporation’s annual report (Form 10-K) for the fiscal year ended September 30, 2008 (including the schedule appearing therein) and the effectiveness of Atmos Energy Corporation’s internal control over financial reporting as of September 30, 2008 have been audited by Ernst & Young LLP, independent registered public accounting firm, as set forth in their reports thereon, included therein, and incorporated herein by reference. Such consolidated financial statements are incorporated herein by reference in reliance upon such reports given on the authority of such firm as experts in accounting and auditing.
 
With respect to the unaudited condensed consolidated interim financial information of Atmos Energy for the three-month periods ended December 31, 2008 and 2007, incorporated herein by reference, Ernst & Young LLP reported that they have applied limited procedures in accordance with professional standards for a review of such information. However, their separate report dated February 3, 2009, included in our quarterly report on Form 10-Q for the three-month period ended December 31, 2008, and incorporated herein by reference, states that they did not audit and they do not express an opinion on that interim financial information. Accordingly, the degree of reliance on their report on such information should be restricted in light of the limited nature of the review procedures applied. Ernst & Young LLP is not subject to the liability provisions of Section 11 of the Securities Act of 1933, as amended, for their report on the unaudited interim financial information because that report is not a “report” or a “part” of the registration statement prepared or certified by Ernst & Young LLP within the meaning of Sections 7 and 11 of the Securities Act of 1933.
