As previously disclosed on December 14, 2016, Stone Energy Corporation (the “Company”) and its subsidiaries, Stone Energy Holding, L.L.C. and Stone Energy Offshore, L.L.C., filed voluntary petitions (the cases commenced thereby, the “Chapter 11 Cases”) seeking relief under Chapter 11 of Title 11 of the United States Code (the “Bankruptcy Code”) in the United States Bankruptcy Court for the Southern District of Texas (the “Bankruptcy Court”) under the caption In re Stone Energy Corporation, et al.

On February 15, 2017, the Bankruptcy Court entered an order, Docket No. 528 (the “Confirmation Order”), confirming the Second Amended Joint Prepackaged Plan of Reorganization of Stone Energy Corporation and its Debtor Affiliates, dated December 28, 2016 (the “Plan”), as modified by the Confirmation Order.

On February 28, 2017 (the “Effective Date”), the Company filed a Current Report on Form 8-K (the “Original Form 8-K”) to report the effectiveness of the Plan, the emergence of the Company and its subsidiaries from the Chapter 11 Cases and related matters under Items 1.01, 1.02, 2.03, 3.02, 3.03, 5.01, 5.02, 5.03 and 9.01 of Form 8-K. Due to the large number of events to be reported under the specified items of Form 8-K, this Form 8-K/A is being filed to amend the Original Form 8-K to include additional matters related to the effectiveness of the Plan under Items 7.01, 8.01 and 9.01 of Form 8-K.

The descriptions of the Plan and the Confirmation Order in this Current Report on Form 8-K (the “Report”) are qualified in their entirety by reference to the full text of the Plan and the Confirmation Order, which are incorporated herein as Exhibit 2.1 and Exhibit 99.1, respectively, to this Report, by reference to the Company’s Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) on February 15, 2017.

All capitalized terms used herein but not otherwise defined in this Report have the meanings set forth in the Plan.

On the Effective Date, the Company issued a press release announcing its emergence from bankruptcy. A copy of this press release is included herein as Exhibit 99.2.

The information included in this Report under Item 7.01 and Exhibit 99.2 attached hereto is being furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to liabilities of that Section, unless the registrant specifically states that the information is to be considered “filed” under the Exchange Act or incorporates it by reference into a filing under the Exchange Act or the Securities Act of 1933, as amended.

On February 23, 2017, pursuant to the terms of the Plan, the New York Stock Exchange (the “NYSE”) approved the listing of shares of common stock of the Company, par value $0.01 (the “New Common Stock”), for trading on the NYSE. On the Effective Date, pursuant to the terms of the Plan, the Company registered the New Common Stock under Section 12(b) of the Exchange Act. Trading in the New Common Stock is expected to commence on the NYSE on March 1, 2017.
