EQT Corporation - Registration Statement on Form S-3 Filed on September 16, 2022

Ladies and Gentlemen:

We have acted as counsel for EQT Corporation, a Pennsylvania corporation (the “Company”), in connection with its filing of a Registration Statement on Form S-3 under the Securities Act of 1933, as amended (the “Act”), with the Securities and Exchange Commission (the “Commission”) on the date hereof (the “Registration Statement”). The Registration Statement relates to the proposed offer and sale by the Company from time to time, in one or more offerings, as set forth in the prospectus contained in the Registration Statement (the “Prospectus”) and as shall be set forth in one or more supplements to the Prospectus (each, a “Prospectus Supplement”), of securities (the “Securities”), which may include any or all of the following: (i) one or more series of the Company’s debt securities, which may be senior debt securities (the “Senior Debt Securities”), subordinated debt securities (the “Subordinated Debt Securities”), or junior subordinated debt securities (the “Junior Subordinated Debt Securities” and, together with the Senior Debt Securities and Subordinated Debt Securities, the “Debt Securities”); (ii) shares of one or more series of preferred stock, no par value, of the Company (the “Preferred Stock”); (iii) shares of common stock, no par value, of the Company (the “Common Stock”); or (iv) any combination of the Securities described in clauses (i) – (iii).

This opinion letter is furnished in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Act.

In connection with this opinion letter, we have examined the Registration Statement and originals or copies, certified or otherwise identified to our satisfaction, of: (i) the Restated Articles of Incorporation of the Company, as amended through July 23, 2020 (the “Articles”); (ii) the Amended and Restated Bylaws of the Company, as amended through May 1, 2020) (the “Bylaws”); (iii) certain resolutions of the Company’s Board of Directors relating to the Registration Statement; and (iv) such other documents, records, and other instruments as we have deemed appropriate for purposes of the opinions set forth herein.

We have assumed the genuineness of all signatures, the legal capacity of all natural persons, the authenticity of the documents submitted to us as originals, the conformity with the originals of all documents submitted to us as certified, facsimile, or photostatic copies, and the authenticity of the originals of all documents submitted to us as copies. With respect to matters of fact relevant to our opinions as set forth below, we have relied upon certificates of officers of the Company, representations made by the Company in documents examined by us, and representations of officers of the Company. We have also obtained and relied upon such certificates and assurances from public officials as we have deemed necessary for the purposes of our opinions set forth below.

For the purposes of the opinions set forth below, we have also assumed, without independent investigation or verification, that:

the issuance, sale, number, or amount, as the case may be, and terms of Securities to be offered from time to time will be duly authorized and established in accordance with the Articles, the Bylaws, and applicable Pennsylvania law (each, a “Corporate Action”), and will not conflict with or constitute a breach of the terms of any agreement or instrument to which the Company is subject;

prior to the issuance of shares of one or more series of Preferred Stock, an appropriate certificate of designation relating to each such series of Preferred Stock will have been duly authorized by Corporate Action and filed with the Secretary of the Commonwealth of Pennsylvania;

the Registration Statement and any amendments thereto (including post-effective amendments) will be effective and such effectiveness shall not have been terminated or rescinded and will comply with all applicable federal and state laws at the time the Securities are offered and issued as contemplated by the Registration Statement;

a Prospectus Supplement will have been prepared, delivered (including through compliance with Rule 172 of the General Rules and Regulations promulgated under the Act), and filed with the Commission describing the Securities offered thereby and will comply with all applicable laws at the time the Securities are offered and issued as contemplated by the Registration Statement;

all Securities will be issued and sold in compliance with applicable federal and state securities laws; and

a definitive purchase, underwriting, or similar agreement (each, a “Definitive Agreement”) with respect to any Securities offered or issued will have been duly authorized and validly executed and delivered by the Company and the other parties thereto.
