We have acted as counsel to EQT Corporation, a Pennsylvania corporation (the “Company”), in connection with the sale by the Company of $500,000,000 principal amount of its 5.678% Senior Notes due 2025 (the “2025 Notes”) and $500,000,000 principal amount of its 5.700% Senior Notes due 2028 (the “2028 Notes” and, together with the 2025 Notes, the “Securities”), under the Registration Statement on Form S-3 (Reg. No. 333-267475) (the “Shelf Registration Statement”) filed by the Company with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Act”), on September 16, 2022. The Securities were offered for sale pursuant to the final prospectus supplement of the Company dated September 20, 2022, including the accompanying base prospectus dated September 16, 2022 (the “Base Prospectus”), which was filed by the Company with the Commission on September 22, 2022, pursuant to Rule 424(b)(5) promulgated under the Act (the “Supplemental Prospectus” and, together with the Base Prospectus, the “Prospectus”).

The 2028 Notes are to be issued pursuant to the Base Indenture, as supplemented by a Fifteenth Supplemental Indenture to be dated as of the date hereof (the “Fifteenth Supplemental Indenture” and, together with the Base Indenture, the “2028 Notes Indenture”), between the Company and the Trustee. As used herein, the term “Supplemental Indentures” refers to the Fourteenth Supplement Indenture and the Fifteenth Supplemental Indenture, and the term “Indentures” refers to the 2025 Notes Indenture and the 2028 Notes Indenture.

As to all matters of fact (including factual conclusions and characterizations and descriptions of purpose, intention, or other state of mind), we have relied, with your permission, entirely upon written actions by the board of directors of the Company and certificates of certain officers of the Company and have assumed, without independent inquiry, the accuracy of those certificates and written actions by the board of directors of the Company.
