Ladies and Gentlemen:

We have acted as special Virginia counsel to Atmos Energy Corporation, a Texas and Virginia corporation (the “Company”), in connection with the preparation and filing by the Company of a Registration Statement on FormS-3 (the “Registration Statement”) filed on the date hereof with the Securities and Exchange Commission (the “Commission”) pursuant to the Securities Act of 1933, as amended (the “Act”). The Registration Statement relates to the registration and proposed issuance and sale from time to time by the Company of up to a maximum aggregate offering price of $4,000,000,000 of (i) debt securities which the Company may issue in one or more series and which may include provisions regarding conversion of the debt securities into the Company’s common stock (the “Debt Securities”) and (ii) shares of the Company’s common stock, no par value per share (the “Common Stock,” and together with the Debt Securities, the “Securities”). The Securities are to be issued in one or more series and will be offered on a continuous or delayed basis pursuant to Rule 415 of the Act, from time to time as set forth in the Registration Statement, the prospectus contained therein (the “Prospectus”) and any amendments or supplements thereto.

This opinion letter is being furnished in accordance with the requirements of Item 16 of FormS-3 and Item 601(b)(5)(i) of RegulationS-K promulgated under the Act.

In connection with this opinion letter, we have examined originals or copies, certified or otherwise identified to our satisfaction, of such corporate records of the Company, certificates of corporate officers of the Company and public officials and such other documents as we have deemed necessary for the purposes of rendering this opinion, including, among other things, (i) the Company’s Virginia Restated Articles of Incorporation (the “Articles of Incorporation”) and the Company’s Amended and Restated Bylaws (the “Bylaws”), each as amended through the date hereof, (ii) a certificate issued by the State Corporation Commission of the Commonwealth of Virginia on the date hereof, to the effect

that the Company is existing under the laws of the Commonwealth of Virginia and in good standing, (iii) resolutions of the Board of Directors of the Company adopted at a meeting held on November 5, 2019, (iv) the Registration Statement, and (v) a copy of the indenture, dated as of March 26, 2009 (the “Indenture”), between the Company and U.S. Bank National Association, as trustee.

For purposes of the opinions expressed below, we have assumed (i) the authenticity of all documents submitted to us as originals, (ii) the conformity to the originals of all documents submitted to us as certified, photostatic or electronic copies and the authenticity of the originals thereof, (iii) the accuracy, completeness and authenticity of all corporate records and other information made available to us by the Company, (iv) the legal capacity of natural persons, (v) the genuineness of all signatures not witnessed by us and (vi) the due authorization, execution and delivery of all documents by all parties and the validity, binding effect and enforceability thereof on such parties (other than the authorization, execution and delivery of documents by the Company).

As to factual matters, including the execution and delivery of the Indenture and the Securities by officers of the Company, we have relied upon, and assumed the accuracy of, representations included in the documents submitted to us, upon certificates and other comparable documents of officers and representatives of the Company, upon statements made to us in discussions with management and upon certificates of public officials. Except as otherwise expressly indicated, we have not undertaken any independent investigation of factual matters.

We do not purport to express an opinion on any laws other than those of the Commonwealth of Virginia. We express no opinion as to the effect of the laws of the State of Texas on the issuance, payment and nonassessability of the Securities.

The opinions set forth herein are subject to the following assumptions, qualifications and limitations being true and correct at or prior to the time of the delivery of the applicable Security:

(c)    the Board of Directors of the Company will have duly authorized and taken any necessary corporate action to approve (i) each proposed issuance and sale of Debt Securities, and in the case of any Debt Securities convertible into Common Stock (a “Convertible Security”), in conformity with the Articles of Incorporation and Bylaws, each as amended through such time, and (ii) the execution, delivery and performance of the Company’s obligations under the Debt Securities and any related documentation, and such authorization shall remain in effect and unchanged at all times during which such Debt Securities are offered and will not have been modified or rescinded (subject to the further assumption that the sale of any Debt Securities takes place in accordance with such authorization);

(d)    the Registration Statement, and any amendments thereto (including post-effective amendments), filed under the Act and the effectiveness thereof will not have been terminated or rescinded and will comply with all applicable laws;

(e)    a prospectus supplement (a “Prospectus Supplement”) will have been prepared and filed with the SEC describing the Securities offered thereby;

Based upon the foregoing and such other information and documents as we have considered necessary for the purposes hereof, and subject to the assumptions, qualifications and limitations stated herein, we are of the opinion that (subject to compliance with the pertinent provisions of the Act, and to compliance with such securities or “blue sky” laws of any jurisdiction as may be applicable):

4.    When shares of Common Stock shall have been authorized, issued and sold within the limits and as described in the Registration Statement, and if in an underwritten offering, in accordance with the terms and conditions of the applicable purchase, underwriting or similar agreement, and in a manner contemplated in the Registration Statement, including the Prospectus Supplement relating to the applicable offering of such Common Stock, the shares of Common Stock will be validly issued, will be fully paid and nonassessable.

In giving this consent, we do not admit that we are within the category of persons whose consent is required by Section 7 of the Act or the rules and regulations of the Commission promulgated thereunder.

Our opinions are expressly limited to the matters set forth above and we render no opinions, whether by implication or otherwise, as to any other matters relating to the Company or the Securities.
