NEWS RELEASE

BONANZA CREEK to continue listing new shares of common stock under ticker “bcei” following emergence from chapter 11 reorganization

DENVER, Colorado – April 27, 2017 /Globe Newswire/ – Bonanza Creek Energy, Inc. (NYSE: BCEI) (“Bonanza Creek” or the “Company”) today announced that the Company received approval to list its new common stock with the CUSIP number 097793 400 (the “New Common Shares”) on the New York Stock Exchange (the “NYSE”) under the same NYSE ticker symbol “BCEI” as the existing shares of the Company’s issued common stock (the “Existing Shares”), in connection with the Company’s anticipated emergence from chapter 11 reorganization in accordance with the Third Amended Joint Prepackaged Plan of Reorganization of Bonanza Creek and its Subsidiaries, dated April 6, 2017 (the “Plan”) that was confirmed on April 7, 2017 by the United States Bankruptcy Court for the District of Delaware.

The Company currently expects the Plan to become effective on or around April 28, 2017, at which point the Company and its debtor subsidiaries will emerge from bankruptcy (the “Effective Date”). Upon emergence, the Company will issue New Common Shares as well as warrants with the CUSIP number 097793 111 (the “Warrants”) in accordance with the Plan. All Existing Shares (with the CUSIP number 097793 103) will be cancelled after the close of business on the Effective Date, and the New Common Shares and Warrants will be issued at such time.

Assuming the Effective Date occurs on Friday, April 28, 2017, trading in the New Common Shares is expected to commence on Monday, May 1, 2017, under the ticker symbol “BCEI,” which is the same trading symbol used for the Company’s Existing Shares listed on the NYSE. The Warrants will not be listed on an exchange.

Because the Company will retain the ticker symbol “BCEI” after the Effective Date of the Plan, holders of Existing Shares, and brokers, dealers and agents effecting trades in Existing Shares, and persons who expect to receive New Common Shares or effect trades in New Common Shares, should take note of the anticipated cancellation of the Existing Shares and issuance of New Common Shares, and the two different CUSIP numbers signifying the Existing Shares and the New Common Shares, in trading or taking any other actions in respect of shares of the Company that trade under the “BCEI” ticker.

The occurrence of the Effective Date is subject to conditions set forth in the Plan, and the Company can make no assurances as to whether the Effective Date will occur on April 28, 2017, or at all.
