 Each of the
undersigned, Christopher T. Forsythe, Senior Vice President and Chief Financial Officer, and Phillip L. Allbritten, Associate General Counsel and Assistant Corporate Secretary of Atmos Energy Corporation (the “Company”) certifies, pursuant
to the authority delegated to each of them, as an officer of the Company, pursuant to the resolutions adopted by the board of directors of the Company (the “Board”) on May 2, 2017 (copies of which resolutions are attached hereto as
Exhibit I), that pursuant to Section 301 of the Indenture dated as of March 26, 2009 (the “Indenture”) between the Company and U.S. Bank National Association, as trustee (the “Trustee”), the series of debt
securities of the Company described herein are hereby established with the following terms and provisions (unless otherwise defined herein, capitalized terms used herein have the meaning given thereto in the Indenture): 

1.    The titles of the series of securities to be issued are the 3.000% Senior Notes due 2027 (the
“2027 Notes”) and the 4.125% Senior Notes due 2044 (the “additional 2044 Notes”). The additional 2044 Notes are an additional issuance of the Company’s 4.125% Senior Notes due 2044 originally issued on October 15, 2014
(the additional 2044 Notes, together with the previously issued 4.125% Senior Notes due 2044, the “2044 Notes;” and the 2027 Notes, together with the additional 2044 Notes, the “Notes”). 

2.    The Notes are unsubordinated and will rank equally with all of the Company’s other unsecured and
unsubordinated debt. Subordinated debt will rank junior to the Notes and the Company’s other senior debt. 

3.    Prior to the issuance of the additional 2044 Notes, there are $500,000,000 aggregate principal amount
of 2044 Notes outstanding under the Indenture. The aggregate principal amount of the additional 2044 Notes that initially may be issued under the Indenture, in connection with the Underwriting Agreement, dated as of June 5, 2017, among the
Company and certain underwriters named therein (the “Underwriting Agreement”), is $250,000,000, and the Stated Maturity of the 2044 Notes is October 15, 2044. The additional 2044 Notes shall be offered to the public at a price
representing 103.907% of their principal amount. 
 4.    The aggregate principal amount of the 2027
Notes that initially may be issued under the Indenture, in connection with the Underwriting Agreement, is $500,000,000, and the Stated Maturity of the 2027 Notes is June 15, 2027. The 2027 Notes shall be offered to the public at a price
representing 99.725% of their principal amount. 
 5.    The additional 2044 Notes shall bear interest at
the rate of 4.125% per annum. Interest on the additional 2044 Notes will be payable in arrears on April 15 and October 15 of each year (each, a “2044 Notes Interest Payment Date”), beginning October 15, 2017. Interest
payable on each 2044 Notes Interest Payment Date will 

  
 1 








 
include interest accrued from and including April 15, 2017, or from and including the most recent 2044 Notes Interest Payment Date to which interest has been paid or duly provided for, as
the case may be, to but excluding such 2044 Notes Interest Payment Date. Interest will be computed on the basis of a 360-day year of twelve 30-day months. The interest
so payable, and punctually paid or duly provided for, on any 2044 Notes Interest Payment Date will, as provided in the Indenture, be paid to the Holder in whose name the 2044 Notes are registered at the close of business on the April 1 or
October 1 (whether or not a Business Day) preceding the respective 2044 Notes Interest Payment Date. The payment of any Defaulted Interest on the 2044 Notes shall be payable to the Holders of the 2044 Notes on a Special Record Date established
therefor pursuant to the Indenture, or shall be paid at any time in any other lawful manner, all as more fully provided in the Indenture. 

6.    The 2027 Notes shall bear interest at the rate of 3.000% per annum. Interest on the 2027 Notes will

from and including June 8, 2017, or from and including the most recent 2027 Notes Interest Payment Date to which interest has been paid or duly provided for, as the case may be, to but excluding such 2027 Notes Interest Payment Date. Interest
will be computed on the basis of a 360-day year of twelve 30-day months. The interest so payable, and punctually paid or duly provided for, on any 2027 Notes Interest
Payment Date will, as provided in the Indenture, be paid to the Holder in whose name the 2027 Notes are registered at the close of business on the June 1 or December 1 (whether or not a Business Day) preceding the respective 2027 Notes
Interest Payment Date. The payment of any Defaulted Interest on the 2027 Notes shall be payable to the Holders of the 2027 Notes on a Special Record Date established therefor pursuant to the Indenture, or shall be paid at any time in any other
lawful manner, all as more fully provided in the Indenture. 
 7.    Payment of the principal of (and
premium, if any) and interest on the Notes will be made at the office or agency of the Company maintained for that purpose in the Borough of Manhattan, the City of New York, or at such other office or agency of the Company as may be maintained for
such purpose, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. So long as the Notes remain in book-entry form, all payments of principal and interest will be
made by the Company in immediately available funds. 
 8.    The Company may redeem the 2044 Notes prior

below) plus 15 basis points; plus, in each case, accrued and unpaid interest on the principal amount of 2044 Notes being redeemed to the Redemption Date. 

At any time on or after April 15, 2044, the Redemption Price with respect to the 2044 Notes shall be equal to 100% of the principal amount
of the 2044 Notes to be redeemed, plus accrued and unpaid interest thereon to the Redemption Date.

time to time in part. Prior to March 15, 2027, the Redemption Price with respect to the 2027 Notes shall be equal to the greater of:

Remaining Scheduled Payments (as defined below) of principal and interest on the 2027 Notes to be redeemed that would be due if the 2027 Notes matured on the Par Call Date (as defined below), 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 (as defined below) plus 15 basis points; plus, in each case, accrued and unpaid
interest on the principal amount of 2027 Notes being redeemed to the Redemption Date. 
 At any time on or after March 15, 2027, the
Redemption Price with respect to the 2027 Notes shall be equal to 100% of the principal amount of the 2027 Notes to be redeemed, plus accrued and unpaid interest thereon to the Redemption Date. 

“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, with respect to a series of Notes, the United States Treasury security selected by
the Quotation Agent as having a maturity comparable to the remaining term of the Notes of such series to be redeemed (assuming, with respect to the 2027 Notes, that they matured on the Par Call Date) 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 of such series to be redeemed; 

“Comparable Treasury Price” means, for any Redemption Date, the average of the Reference Treasury Dealer Quotations

Notes;

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 at 5:00 p.m., Eastern time
by such Reference Treasury Dealer on the third Business Day preceding such Redemption Date; and 
 “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 a 2044 Notes Interest Payment Date with respect to the additional 2044 Notes or a 2027 Notes Interest Payment Date with respect to the 2027 Notes, 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. 
 10.    In the case
of a partial redemption of the Notes of a series, the Notes to be redeemed shall be selected by the Trustee from the outstanding Notes of such series not previously called for redemption, in the case of the 2027 Notes, in accordance with the
procedures of the Depository and, in the case of the 2044 Notes, by such method as the Trustee shall deem fair and appropriate (or, in the case of Notes issued in global form, by such method as the Depository may require), and, in each case, which
may provide for the selection for redemption of portions of the principal of the Notes of such series. A partial redemption shall not reduce the portion of the principal amount of a Note not redeemed to a principal amount of less than $2,000. 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 of the series 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 the Notes of the series to be redeemed. 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 the Company defaults 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.

Company pursuant to Subsections (1) and (2) of this Section 703 as may be required by rules and regulations prescribed from time to time by the Commission.

permanent global form and each evidenced by a global security (a “Global Security”) in substantially the form attached hereto as Exhibit II-A, and the 2027 Notes will be issued in registered
permanent global form and each evidenced by a Global Security in substantially the form attached hereto as Exhibit II-B, with such appropriate insertions, omissions, substitutions and other variations

any rules or regulations pursuant thereto, or with any rules of any securities exchange or to conform to general usage, all as may be determined by the officers executing each such Global Security, as evidenced by their execution of such Global
Security. The beneficial owners of interests in each of the Global Securities may exchange such interests for the applicable series of Notes in certificated form (the “Definitive Notes”) only in limited circumstances as provided in the
Indenture. In the event that Definitive Notes are issued in exchange for a Global Security, the form of certificate evidencing each Definitive Note shall be in substantially the form of the applicable attached Global Security, with such changes as

terms as to status, redemption and otherwise as the Notes of such series under the Indenture. 
 Each of us further certifies that the form
and terms of the Notes as established in this certificate have been established pursuant to Section 301 of the Indenture and comply with the Indenture.

 Atmos Energy Corporation, a Texas and Virginia corporation (herein called the
“Company”, which term includes any successor entity under the Indenture, hereinafter defined), for value received, hereby promises to pay to Cede & Co. or registered assigns the principal sum of TWO HUNDRED AND FIFTY MILLION
DOLLARS ($250,000,000) on October 15, 2044 (the “Maturity Date”), at the office or agency of the Company referred to below, and to pay interest thereon from April 15, 2017, or from the most recent Interest Payment Date to which
interest has been paid or duly provided for, semiannually in arrears on April 15 and October 15 in each year (each, an “Interest Payment Date”), beginning October 15, 2017 at 4.125% per annum until the principal hereof is
paid or duly provided for. 
 Any payment of principal or interest required to be made on a day that is not a Business Day need not be made
on such day, but may be made on the next succeeding Business Day with the same force and effect as if made on such day and no interest shall accrue as a result of such delayed payment. Interest payable on each Interest Payment Date will include
interest accrued from and including April 15, 2017, or from and including the most recent Interest Payment Date to which interest has been paid or duly provided for, as the case may be, to but excluding such Interest Payment Date. Interest will
be computed on the basis of a 360-day year of twelve 30-day months. 

The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in the Indenture, be paid to
the person (the “Holder”) in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the April 1 or October 1 (whether or not a Business Day) next preceding such Interest Payment
Date (a “Regular Record Date”). Any such interest not so punctually paid or duly provided for (“Defaulted Interest”) will forthwith cease to be payable to the Holder on such Regular Record Date and either may be paid to the
Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a special record date (the “Special Record Date”) for the payment of such Defaulted Interest to be fixed by the Trustee
(referred to herein), notice whereof shall be given to the Holder of this Security not less than ten days prior to such Special Record Date, or may be paid at any time in any other lawful manner, all as more fully provided in the Indenture. 

For purposes of this Security, “Business Day” means any day that, in the city of the principal Corporate Trust Office of the Trustee

 Unless the certificate of authentication hereon has been duly executed by the Trustee by manual
signature, this Security shall not be entitled to any benefit under the Indenture, or be valid or obligatory for any purpose. 
 This
Security is one of a duly authorized issue of securities of the Company, designated as the 4.125% Senior Notes due 2044 (the “Securities”), originally issued in an aggregate principal amount of $500,000,000 on October 15, 2014 and, as
a result of a further issuance of $250,000,000 aggregate principal amount of 4.125% Senior Notes due 2044 on June 8, 2017, now issued in an aggregate principal amount of $750,000,000 under an Indenture dated as of March 26, 2009, as it may
be supplemented from time to time (referred to herein as the “Indenture”), between the Company and U.S. Bank National Association, as trustee (referred to herein as the “Trustee”, which term includes any successor trustee under
the Indenture with respect to the series of which this Security is a part). A reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties, obligations and immunities thereunder of the Company,
the Trustee and the Holders of the Securities, and of the terms upon which the Securities are, and are to be, authenticated and delivered, except as otherwise provided herein. 

The Securities are initially limited to $750,000,000 aggregate principal amount. The Company may, at any time, without the consent of the
Holders of the Securities, create and issue additional securities having the same ranking, interest rate, maturity and other terms as the Securities. Any such additional securities shall be consolidated and form the same series of the Securities
having the same terms as to status, redemption and otherwise as the Securities under the Indenture. 
 Events of Default. If an Event
of Default shall occur and be continuing, the principal of all the Securities may be declared due and payable in the manner and with the effect provided in the Indenture. 

Optional Redemption. The Securities will be redeemable prior to maturity at the Company’s option, at any time in whole or from
time to time in part. Prior to April 15, 2044, the Redemption Price will be equal to the greater of: 
 (a)    100%
of the principal amount of the Securities to be redeemed, and 
 (b)    as determined by the Quotation Agent, the sum of
the present values of the Remaining Scheduled Payments of principal and interest on the Securities 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 plus 15 basis points; 
 plus, in each case, accrued and unpaid
interest on the principal amount of Securities being redeemed to the Redemption Date. 
 At any time on or after April 15, 2044, the Redemption Price
will be equal to 100% of the principal amount of the Securities to be redeemed, plus accrued and unpaid interest thereon to the Redemption Date. 

  
 14 








 “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 Securities 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 Securities 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 the
Company to act as a quotation agent. 
 “Reference Treasury Dealer” means (i) Merrill Lynch, Pierce, Fenner & Smith
Incorporated and any Primary Treasury Dealer (as defined below) selected by each of Credit Agricole Securities (USA) Inc. and Wells Fargo Securities, LLC and any of such parties’ successors; provided, however, if any of the foregoing ceases to
be a primary U.S. government securities dealer in New York City (a “Primary Treasury Dealer”), the Company will substitute therefor another Primary Treasury Dealer, and (ii) any other Primary Treasury Dealer selected by the Company.

 “Reference Treasury Dealer Quotation” means, with respect to each Reference Treasury Dealer and 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 at 5:00 p.m., Eastern time by such Reference
Treasury Dealer on the third Business Day preceding such Redemption Date. 
 “Remaining Scheduled Payments” means, with respect to
each Security to be redeemed, the remaining scheduled payments of the principal and interest on such Security 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 Security will be reduced by the amount of interest accrued on such Security to such Redemption Date. 

In the event that less than all of the Securities are to be redeemed at any time, selection of such Securities for redemption will be made by
The Depository Trust Company (“DTC”) during any period the Securities are issued in the form of a global security registered in the name of DTC or a nominee thereof; provided that during any period the Securities are issued in
certificated form, the selection of such Securities for redemption will be made by the Trustee by lot or by such other method as the Trustee in its sole discretion shall deem fair and appropriate (or, in the case of Securities issued in global form,
by such method as the depositary may require) and which may provide for the selection for redemption of portions of the principal of the Securities. A partial redemption shall not reduce the portion of the principal amount of a


  
 15 








 
Security not redeemed to a principal amount of less than $2,000. Notice of redemption shall be given by first-class mail, postage prepaid, mailed not less than 30 nor more than 60 days before the
Redemption Date, to each Holder of Securities to be redeemed, at its address as shown in the Security Register. If the Securities are to be redeemed in part only, the notice of redemption that relates to such Securities shall state the portion of
the principal amount thereof to be redeemed. A new Security in a principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon surrender for cancellation of the original Security. On and after the
Redemption Date, interest will cease to accrue on Securities or portions thereof called for redemption unless the Company defaults in the payment of the Redemption Price. 

Sinking Fund. This Security does not have the benefit of any sinking fund obligations. 

Modification and Waivers; Obligations of the Company Absolute. The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities. Certain limited amendments may be effected under the Indenture at any time by the Company and the Trustee without
the consent of any Holders of the Securities. Certain other amendments affecting the Securities may only be effected under the Indenture with the consent of the Holders of not less than a majority in aggregate principal amount of the Securities at
the time Outstanding. The Indenture also contains provisions permitting the Holders of not less than a majority in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive
compliance by the Company with certain provisions of the Indenture affecting the Securities. Furthermore, provisions in the Indenture permit the Holders of not less than a majority in principal amount of the Outstanding Securities to waive on behalf
of all of the Holders of all Outstanding Securities certain past defaults under the Indenture in respect of the Securities and their consequences. Any such consent or waiver by or on behalf of the Holder of this Security shall be conclusive and
binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof whether or not notation of such consent or waiver is made upon this
Security. 
 No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation
of the Company, which is absolute and unconditional, to pay the principal of (and premium, if any) and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed. 

Defeasance and Covenant Defeasance. The Indenture contains provisions for defeasance at any time of (a) the entire indebtedness of
the Company represented by this Security and (b) certain restrictive covenants and the related Defaults and Events of Default, upon compliance by the Company with certain conditions set forth therein, which provisions apply to this Security.

 Authorized Denominations. The Securities are issuable only in registered form, without coupons, in minimum denominations of $2,000
and any integral multiple of $1,000 in excess thereof. 

  
 16 








 Registration of Transfer or Exchange. As provided in the Indenture and subject to certain
limitations therein set forth, the transfer of this Security is registrable on the Security Register of the Company, upon surrender of this Security for registration of transfer at the office or agency of the Company, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities, of authorized
denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. At the date of the original issuance of this Security such office or agency of the Company is maintained by U.S. Bank National
Association, 1349 West Peachtree Street, Suite 1050, Atlanta, Georgia 30309. 
 As provided in the Indenture and subject to certain
limitations therein set forth, the Securities are exchangeable for a like aggregate principal amount of Securities of a different authorized denomination, as requested by the Holder surrendering the same. 

No service charge shall be made for any registration of transfer or exchange or redemption of Securities, but the Company may require payment
of a sum sufficient to pay all documentary, stamp or similar issue or transfer taxes or other governmental charges payable in connection with any registration of transfer or exchange. 

Prior to the time of due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or
the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any agent shall be affected by notice to the contrary.

 Defined Terms. All capitalized terms used in this Security which are defined in the Indenture shall have the meanings assigned to
them in the Indenture.

been paid or duly provided for, semiannually in arrears on June 15 and December 15 in each year (each, an “Interest Payment Date”), beginning December 15, 2017 at 3.000% per annum until the principal hereof is paid or duly
provided for. 
 Any payment of principal or interest required to be made on a day that is not a Business Day need not be made on such day,
but may be made on the next succeeding Business Day with the same force and effect as if made on such day and no interest shall accrue as a result of such delayed payment. Interest payable on each Interest Payment Date will include interest accrued
from and including June 8, 2017, or from and including the most recent Interest Payment Date to which interest has been paid or duly provided for, as the case may be, to but excluding such Interest Payment Date. Interest will be computed on the

 The
interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in the Indenture, be paid to the person (the “Holder”) in whose name this Security (or one or more Predecessor Securities) is
registered at the close of business on the June 1 and December 1 (whether or not a Business Day) next preceding such Interest Payment Date (a “Regular Record Date”). Any such interest not so punctually paid or duly provided for
(“Defaulted Interest”) will forthwith cease to be payable to the Holder on such Regular Record Date and either may be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of
business on a special record date (the “Special Record Date”) for the payment of such Defaulted Interest to be fixed by the Trustee (referred to herein), notice whereof shall be given to the Holder of this Security not less than ten days
prior to such Special Record Date, or may be paid at any time in any other lawful manner, all as more fully provided in the Indenture. 

For purposes of this Security, “Business Day” means any day that, in the city of the principal Corporate Trust Office of the Trustee
and in the City of New York, is neither a Saturday, Sunday, or legal holiday nor a day on which banking institutions are authorized or required by law or regulation to close. 

Payment of the principal of (and premium, if any) and interest on this Security will be made at the office or agency of the Company maintained
for that purpose in the Borough of Manhattan, the City of New York, or at such other office or agency of the Company as may be maintained for such purpose, in such coin or currency of the United States of America as at the time of payment is legal
tender for payment of public and private debts. So long as this Security remains in book-entry form, all payments of principal and interest will be made by the Company in immediately available funds.
