Item 4.01 Changes in Registrant’s CertifyingAccountant

As previously reported on its current report on Form 8-K filed January 15, 2026 (the “Original Report”), the Audit Committee (the “Audit Committee”) of the Board of Directors of Amplify Energy Corp. (the “Company”), with the assistance of the Company’s management, completed a competitive process to select the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2026 (“Fiscal 2026”). At the conclusion of this process, on January 12, 2026, the Audit Committee approved the dismissal of Deloitte & Touche LLP (“Deloitte”), effective upon completion of their audit of the Company’s consolidated financial statements as of and for the year ended December 31, 2025 and the effectiveness of internal control over financial reporting as of December 31, 2025, and the issuance of their reports thereon (together, the “Final Audit Reports”).

This Current Report on Form 8-K/A amends the Original Report to confirm that, upon Deloitte’s issuance of the Final Audit Reports in connection with the Company’s filing of its Annual Report on Form 10-K for the fiscal year ended December 31, 2025, Deloitte completed its engagement. The Final Audit Reports were issued March 9, 2026.

The audit report of Deloitte on the Company’s consolidated financial statements as of and for the years ended December 31, 2025 and 2024 did not contain an adverse opinion or disclaimer of opinion, nor was it qualified or modified as to uncertainty, audit scope, or accounting principles. The audit report of Deloitte on the Company’s internal control over financial reporting as of December 31, 2025 contained an adverse opinion regarding a material weakness in the Company’s internal control over financial reporting related to the lack of the appropriate control processes and activities to sufficiently mitigate for changes in personnel with the necessary technical and accounting knowledge, experience, and training (the “Material Weakness”).

The Material Weakness was discussed among the Audit Committee and Deloitte. Deloitte has been authorized by the Company to respond fully to any inquiries, including the Material Weakness, by Grant Thornton LLP (“Grant Thornton”), the Company’s independent registered public accounting firm appointed for Fiscal 2026.

During the fiscal years ended December 31, 2025 and 2024, and the subsequent interim period through March 9, 2026 there were no: (1) disagreements (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) with Deloitte on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedures, which disagreements, if not resolved to the satisfaction of Deloitte would have caused Deloitte to make reference thereto in its reports on the consolidated financial statements for such years, or (2) reportable events (as described in Item 304 (a)(1)(v) of Regulation S-K) other than the Material Weakness.

The Company delivered a copy of this Current Report on Form 8-K/A to Deloitte prior to filing with the U.S. Securities and Exchange Commission (“SEC”) and requested that Deloitte provide the Company with a letter addressed to the SEC stating whether or not it agrees with the statements made in response to this Item and, if not, stating the respects in which it does not agree. Deloitte responded with a letter dated March 13, 2026, stating that Deloitte agrees with the statements set forth above, a copy of which is filed as Exhibit 16.1 to this Current Report on Form 8-K/A.

Also, as previously reported on the Original Report, on January 12, 2026, the Audit Committee approved the appointment of Grant Thornton as the Company’s independent registered public accounting firm for Fiscal 2026, effective upon the dismissal of Deloitte and the completion of Grant Thornton’s client acceptance procedures. This Current Report on Form 8-K/A amends the Original Report to confirm that the appointment of Grant Thornton as the Company’s independent registered public accounting firm for Fiscal 2026 became effective on March 11, 2026 upon the completion of Grant Thornton’s client acceptance procedures.

During the years ended December 31, 2025 and 2024, and the subsequent interim period through March 11, 2026, neither the Company nor anyone on their behalf consulted with Grant Thornton regarding either (i) the application of accounting principles to a specific transaction, completed or proposed, or the type of audit opinion that might be rendered on the Company’s financial statements, and neither a written report nor oral advice was provided to the Company that Grant Thornton concluded was an important factor considered by the Company in reaching a decision as to any accounting, auditing or financial reporting issue or (ii) any matter that was either the subject of a disagreement (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) or a reportable event (as described in Item 304(a)(1)(v) of Regulation S-K).
