Ladies and Gentlemen:

We are issuing this opinion letter in our capacity as special counsel to Amplify Energy Corp., a Delaware corporation (the “Company”), in connection with the preparation of the Registration Statement on Form S-8 (as amended or supplemented, the “Registration Statement”) filed with the Securities and Exchange Commission (the “Commission”) on June 11, 2026 under the Securities Act of 1933, as amended (the “Securities Act”), by the Company. The Registration Statement relates to the registration by the Company of up to an additional 3,100,000 shares of Common Stock of the Company, par value $0.01 per share, issuable under the Amplify Energy Corp. 2024 Amended and Restated Equity Incentive Plan (the “A&R 2024 Plan”), including shares of Common Stock that may again become available for delivery with respect to awards under the A&R 2024 Plan pursuant to the share counting, share recycling and other terms and conditions of the A&R 2024 Plan (the “Additional Shares”).

In connection with the registration of the Additional Shares, we have examined originals, or copies certified or otherwise identified to our satisfaction, of such documents, corporate records and other instruments as we have deemed necessary for the purposes of this opinion, including (i) the corporate and organizational documents of the Company, (ii) minutes and records of the corporate proceedings of the Company with respect to the issuance of the Additional Shares pursuant to the A&R 2024 Plan, (iii) the A&R 2024 Plan and (iv) the Registration Statement and the exhibits thereto.

For purposes of this opinion, we have assumed the authenticity of all documents submitted to us as originals, the conformity to the originals of all documents submitted to us as copies and the authenticity of the originals of all documents submitted to us as copies. We have also assumed the legal capacity of all natural persons, the genuineness of the signatures of persons signing all documents in connection with which this opinion is rendered, the authority of such persons signing on behalf of the parties thereto other than the Company and the due authorization, execution and delivery of all documents by the parties thereto other than the Company. We have not independently established or verified any facts relevant to the opinions expressed herein, but have relied upon statements and representations of the officers and other representatives of the Company.

We have relied without independent investigation upon, among other things, an assurance from the Company that the number of shares which the Company is authorized to issue in the Company’s charter exceeds the number of shares outstanding and the number of shares which the Company is obligated to issue (or had otherwise reserved for issuance) for any purposes other than issuance in connection with the A&R 2024 Plan by at least the number of Additional Shares which may be issued in connection with the A&R 2024 Plan and we have assumed that such condition will remain true at all future times relevant to this opinion.

Based upon and subject to the foregoing qualifications, assumptions and limitations and the further limitations set forth below, we are of the opinion that the Additional Shares have been duly authorized and, when issued, delivered and paid for in accordance with the terms of the A&R 2024 Plan, will be validly issued, fully paid and nonassessable.
