I. Executive Summary

Manufacturing Activities

C&J Energy Services is a leading completion and production services provider throughout the continental United States. Further, as explained in more detail herein, the Company manufactures certain equipment and other products used in the energy services industry, which are used in the Company’s operations and also sold to third parties. During the fiscal year ended December 31, 2017, the Company’s manufacturing service lines did not comprise a significant part of the Company’s business, operations or financial results. The Company’s manufacturing activities contributed approximately 1.0% of the Company’s consolidated revenue for calendar year 2017. Please see Section II “Company Overview” for additional information about the Company and the products that it manufactures and formerly manufactured.

Supply Chain

The Company’s supply chain is complex and is heavily reliant on purchases from distributors rather than product manufacturers. There are multiple tiers between the Company and the smelter and country of origin of any conflict minerals used in its manufactured products. The Company does not make purchases of raw or unrefined conflict minerals, nor does the Company make purchases in any of the Covered Countries. Accordingly, the Company must rely upon its suppliers to provide information on the origin of any conflict minerals contained in materials supplied to the Company, including the sources of conflict minerals that are sourced by the Company’s suppliers from sub-tier suppliers.

The Company believes it is essential to establish validated, conflict-free sources of conflict minerals. The Company has advised its suppliers that it expects them to source conflict minerals from certified conflict-free smelters (such as those audited through the Electronic Industry Citizenship Coalition and Global e-Sustainability Initiative Conflict Free Smelter program (“EICC-GeSI CFS Program”)), perform due diligence on the source and chain of custody of the conflict minerals sourced for the Company, and provide an explanation of their due diligence measures to the Company upon request.

C&J Energy Services Conflict Minerals Policy, Compliance Program & Due Diligence Framework for Reasonable Country of Origin Inquiry

The Company is committed to the responsible sourcing of materials and structuring its sourcing practices to avoid supporting conflict, human rights abuses and crimes against humanity. As part of this commitment, the Company has adopted a Conflict Minerals Policy. A copy of the C&J Energy Services Conflict Minerals Policy is available on the Company’s website at: http://www.cjenergy.com/about-us/compliance-ethics/supplier-conduct/.

In accordance with the Company’s Conflict Minerals Policy, the Company has established a Conflict Minerals Compliance Program & Due Diligence Framework to ensure compliance with the Conflict Minerals Policy by all C&J Energy Services companies. The Company’s measures generally include: (1) conducting a “Reasonable Country of Origin” (“RCOI”) focused supply-chain survey with respect to those identified direct suppliers of materials containing conflict minerals using the Electronic Industry Citizenship Coalition and Global e-Sustainability Initiative Conflict Minerals Reporting Template (the “EICC-GeSI Template”), and (2) to the extent the supplier has identified the smelters, comparing those identified smelters against the list of facilities which have been identified as “conflict free” by the EICC-GeSI CFS Program. The Conflict Minerals Compliance team is led by the Company’s Legal department and includes representatives from the Company’s procurement division and Research & Technology division. During 2017, the Company evaluated its manufacturing businesses and divisions to identify those products that the Company manufactured for sale to third parties that contain conflict minerals.

During 2017, any conflict minerals in the Company’s manufactured products were either added by suppliers, or utilized by the Company’s suppliers in the manufacturing processes. The Company requested that each supplier provide information about the nature and origins of any conflict minerals in their materials or products.

Certain materials and components provided to the Company through its supply chain and contained in the equipment that these businesses assemble contain conflict minerals.

For more information about the Company, please see the Company’s website at www.cjenergy.com as well as the Company’s filings with the SEC. Information contained on or available through the Company’s website is not a part of or incorporated into this Report, the accompanying Form SD or any other report that the Company may file with or furnish to the SEC.

III. 2017 Reasonable Country of Origin Inquiry and Conflict Status Conclusion

The Company conducted an analysis of the products that it manufactured for sale to third parties between January 1, 2017 and December 31, 2017 to determine which products contained conflict minerals. The Company then compiled a list of the suppliers of products it determined to contain conflict minerals.

For purposes of the RCOI, the Company requested each of the identified suppliers to provide information regarding their supply chain using the EICC-GeSI Template. Many of the Company’s suppliers are distributors and passed the Company’s RCOI to their suppliers with whom the Company does not have any contractual relationship. The Company surveyed approximately 81 suppliers and approximately 70% of those surveyed suppliers provided some manner of a response to the inquiries made as part of this RCOI; of those responses 100% confirmed that their products contain conflict materials. The cooperating suppliers provided data at either the supplier level or the product level but, in many cases, the supplier responses did not relate specifically or solely to materials supplied to the Company. Many supplier responses discussed the various sources from which they acquire conflict minerals but could not attribute any such purchases to particular products that may have been sold to any particular customer, including to the Company. Some of the suppliers returned EICC-GeSI Templates that were incomplete or only represented a portion of their supply chain.

Based on the results of the RCOI, the Company has determined that some of the conflict minerals contained in its products did not originate in the DRC or an adjoining country. Nevertheless, the Company was unable to determine with any reasonable certainty the source and chain of custody of all of the conflict minerals used in its products during 2017.

IV. 2017 Due Diligence Measures

For the 2017 calendar year, the Company’s due diligence activities included:

1. Submitting the EICC-GeSI Template to suppliers of materials reasonably believed to contain or potentially contain conflict minerals. The EICC-GeSI Template provides a standardized method for the Company’s use in the collection of representations, statements and data from the Company’s suppliers relative to the presence, use, source and chain of custody of conflict minerals in supplier materials that are incorporated in the Company’s manufactured products for sale to end- use customers.

2. Evaluating the smelters identified by the Company’s in the EICC-GeSI Template to determine whether those facilities are considered “conflict free” by the EICC-GeSI CFS Program. The EICC-GeSI CFS Program is a voluntary program whereby an independent third party evaluates smelter procurement activities to determine whether a smelter has sufficiently demonstrated that all materials processed by that smelter originated from sources that do not directly or indirectly finance or benefit armed groups in the Covered Countries.

3. Following-up with suppliers, and with the suppliers of its distributors, by phone and/or email in order to obtain full and complete responses to the RCOI.

4. In numerous instances, the Company received, after repeat inquiries, incomplete information regarding those facilities utilized to process necessary conflict minerals in supplier materials, as well as insufficient information regarding the mine(s) or source(s) of origin of those conflict minerals. Nevertheless, each supplier response was evaluated and, where possible, validated to determine sufficiency, accuracy or completeness of its response. For each supplier response, the Company subsequently assessed whether the conflict minerals identified, or those conflict minerals that may not have been identified, were consistent with the nature and characteristics of the supplied part. For each supplier response that was insufficient, potentially inaccurate or incomplete, the Company contacted that supplier for follow up, sometimes contacting certain suppliers on multiple occasions.
