Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions (see General Instruction A.2. below):

C&J Energy Services Ltd. (“C&J”) and certain of its direct and indirect subsidiaries (the “Company”), including C&J Corporate Services (Bermuda) Ltd. (together with C&J, collectively the “Bermudian Entities”), C&J Energy Production Services-Canada Ltd. and Mobile Data Technologies Ltd. (together, the “Canadian Entities”), have reached an agreement with certain Lenders (as defined below) regarding terms of a financial restructuring plan. The proposed plan will significantly deleverage the Company’s funded indebtedness, including the Company’s entire secured credit facility, pursuant to a consensual debt-to-equity exchange.

To implement the restructuring, the Company expects to voluntarily commence a reorganization under chapter 11 of the U.S. Bankruptcy Code on or before July 17, 2016. Additionally, the Company will commence ancillary proceedings in Canada on behalf of the Canadian Entities and a provisional liquidation proceeding in Bermuda on behalf of the Bermudian Entities. The Company expects to continue operations in the ordinary course throughout the restructuring process.

In connection with the negotiations described below, on July 8, 2016, the Company entered into a Restructuring Support and Lock-Up Agreement (the “Restructuring Support Agreement”), with certain holders of loans (the “Lenders”) under that certain Credit Agreement, dated as of March 24, 2015 (as amended and restated from time to time with all supplements and exhibits thereto, the “Credit Agreement”), who have agreed to, among other things, backstop an equity rights offering (the “Backstop Parties”).

The Restructuring Support Agreement incorporates the economic terms agreed to by the parties, as memorialized in a term sheet dated July 8, 2016 (the “Restructuring Term Sheet”). The Restructuring Support Agreement, which incorporates and attaches the Restructuring Term Sheet, contemplates the implementation of a restructuring of the Company through a debt-to-equity conversion and equity rights offering, which transaction will be effectuated through a chapter 11 plan of reorganization (the “Plan”), which will be subject to Bankruptcy Court approval. The key terms of the restructuring, as contemplated by the Restructuring Support Agreement and Restructuring Term Sheet, are as follows:

Pursuant to the Restructuring Support Agreement, the supporting lenders have agreed to, among other things: (a) use good faith efforts to implement the restructuring; (b) vote all claims and interests held in favor of the Plan; (c) with respect to the Backstop Parties, backstop the Rights Offering; (d) support and not object or opt out of the release provisions under the Plan so long as such release provisions are consistent with the Restructuring Term Sheet; (e) not exercise any right or remedy under the Credit Agreement against an affiliate of the Company that does not file for chapter 11, subject to certain conditions.

The Restructuring Support Agreement contemplates a chapter 11 filing of July 17, 2016. The Restructuring Support Agreement contains certain Plan-related milestones, including deadlines: (a) to file the Plan and related disclosure statement; (b) for entry of interim and final DIP orders; (c) for entry of the disclosure statement order; (d) for entry of the confirmation order; and (e) for the Effective Date to occur.

The foregoing description of the Restructuring Support Agreement is qualified in its entirety by reference to the full text of such agreement, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.

As previously disclosed in a Current Report on Form 8-K filed with the U.S. Securities and Exchange Commission on June 29, 2016, on June 15, 2016, C&J announced that its Board of Directors (the “Board”) had appointed Mr. Donald J. Gawick to serve as C&J’s President and Chief Executive Officer, in addition to continuing to perform his existing duties as C&J’s Chief Operating Officer, a position he has held since 2012. In connection with Mr. Gawick’s appointment to President and Chief Executive Officer, the Board agreed to appoint Mr. Gawick as a director effective immediately upon the earlier of July 15, 2016 and the Company reaching an agreement with its lenders with respect to its ongoing restructuring process (as further described under Item 1.01 of this Current Report). Accordingly, effective July 8, 2016, Mr. Gawick joined the Board as a Class I director in the position vacated by Mr. McMullen, C&J’s prior President, Chief Executive Officer and Chief Financial Officer, in June 2016.

Mr. Gawick is a 37-year veteran of the oilfield services industry and has held numerous senior management positions over the course of his career. Prior to joining C&J, from 2010 to 2012 he served as President and Chief Executive Office of Casedhole Solutions, Inc., a premier wireline services company that C&J acquired in 2012. Mr. Gawick started his oilfield career in 1979 with Schlumberger and between 1979 and 2010, he held numerous senior management positions, focusing on operations and marketing, including oversight of all of Schlumberger’s oilfield business segments. In addition, he has held senior leadership positions in oilfield services in sales, business and new technology development, service delivery and Health-Safety-Environmental management, with assignments throughout the United States, as well as in Canada, Europe, the Far East and Latin America. Mr. Gawick graduated from the University of Manitoba in 1979 with a B.S. in Electrical Engineering.

On July 8, 2016, C&J issued a press release announcing entry into the Restructuring Support Agreement described under Item 1.01 of this Current Report on Form 8-K, a copy of which is furnished as Exhibit 99.1 hereto pursuant to Item 7.01 of Form 8-K.

In accordance with General Instruction B.2 of Form 8-K, the information furnished pursuant to this Item 7.01, and including Exhibit 99.1 furnished herewith, shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), nor shall such be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such a filing.
