Item 4.01       Changes in Registrant’s Certifying Accountant.

On June 19, 2019, the Audit Committee (the “Audit Committee”) of the Board of Directors of Bonanza Creek Energy, Inc. (the “Company”), approved the appointment of Deloitte & Touche LLP (“Deloitte”) as the new independent registered public accounting firm to perform independent audit services for the Company for the fiscal year ending December 31, 2019, effective immediately. The appointment of Deloitte was the result of a competitive request for proposal process undertaken by the Audit Committee. Please see the Audit Committee’s Report in our Notice of Annual Meeting of Stockholders and Proxy Statement, which was filed with the Securities and Exchange Commission on April 24, 2019, for information regarding consideration of this decision. Also on June 19, 2019, the Audit Committee chose to terminate the Company’s employment of Grant Thornton LLP (“Grant Thornton”) as the Company’s independent registered public accounting firm, which was then serving in such capacity, and notified Grant Thornton that it would be dismissed as the independent registered public accounting firm of the Company, effective immediately.

Grant Thornton’s audit report on the Company’s consolidated financial statements for the fiscal years ended December 31, 2018 and December 31, 2017 did not contain an adverse opinion or a disclaimer of opinion and was not qualified or modified as to uncertainty, audit scope or accounting principle.

During the fiscal years ended December 31, 2018 and December 31, 2017 and through the subsequent interim period ending June 19, 2019, there were (i) no disagreements (as that term is defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) between the Company and Grant Thornton on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which, if not resolved to the satisfaction of Grant Thornton would have caused Grant Thornton to make reference to the subject matter thereof in connection with its reports on the consolidated financial statements of the Company for such years, and (ii) no “reportable events” (as that term is defined in Item 304(a)(1)(v) of Regulation S-K).

The Company provided Grant Thornton with a copy of this Form 8-K and requested that Grant Thornton provide the Company with a letter addressed to the Securities and Exchange Commission stating whether or not Grant Thornton agrees with the above disclosures. A copy of Grant Thornton’s letter, dated June 25, 2019, is attached as Exhibit 16.1 to this Form 8-K.

During the fiscal years ended December 31, 2018 and December 31, 2017 and through the subsequent interim period as of June 19, 2019, neither the Company, nor any party on behalf of the Company, consulted with Deloitte with respect to either (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of the audit opinion that might be rendered with respect to the Company’s consolidated financial statements, and no written report or oral advice was provided to the Company by Deloitte that 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 subject to any disagreement (as that term is defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) or a reportable event (as that term is defined in Item 304(a)(1)(v) of Regulation S-K).
