NEWS RELEASE

C&J Energy Services Announces Fourth Quarter 2015 Results

HAMILTON, BERMUDA, February 22, 2016 – C&J Energy Services Ltd. (NYSE: CJES) today reported a net loss of ($321.7 million), or ($2.75) per diluted share, on revenue of $409.0 million for the fourth quarter of 2015, and an Adjusted Net Loss ⁽¹⁾ of ($52.2 million), or ($0.45) per diluted share⁽¹⁾. Adjusted Net Loss⁽¹⁾ excludes the following, net of tax: a $252.5 million, or $2.16 per diluted share, impairment charge; a $17.8 million, or $0.15 per diluted share, inventory write-down; a $3.8 million, or $0.03 per diluted share, charge related to costs associated with the March 2015 combination (the “Transaction”) of C&J Energy Services, Inc. with the completion and production services business of Nabors Industries Ltd. (“Nabors”); a $2.1 million, or $0.02 per diluted share, customer settlement/bad debt write-off; and a $1.6 million, or $0.01 per diluted share, charge related to severance, facility closures and other one-time costs; offset by an $8.3 million, or $0.07 per diluted share, out-of-period adjustment. Adjusted EBITDA⁽¹⁾ totaled $7.7 million for the fourth quarter of 2015.

Due to the continued downturn in the oil and gas industry, and the sustained deterioration in demand for oilfield services, similar to the action taken during the third quarter, we determined that it was necessary to test goodwill for impairment and to test property, plant and equipment (“PP&E”) and intangible assets for recoverability during the fourth quarter of 2015. Certain asset groups within each of our Completion Services segment and Other Services segment failed the recoverability testing, and as a result, we recorded a non-cash pre-tax charge of $393.1 million related to impairment of PP&E for the fourth quarter. With respect to goodwill and other intangible assets, no impairment write-down was deemed necessary for the fourth quarter.

Our 2015 fourth quarter results compare with a net loss of ($455.0 million), or ($3.89) per diluted share, on revenue of $427.5 million for the third quarter of 2015, and an Adjusted Net Loss⁽¹⁾ of ($76.5 million), or ($0.65) per diluted share⁽¹⁾, for the same period. Adjusted Net Loss⁽¹⁾ for the third quarter of 2015 excluded the following, net of tax: a $367.8 million, or $3.15 per diluted share, impairment charge; a $5.2 million, or $0.05 per diluted share, charge related to costs associated with the Transaction; a $2.7 million, or $0.02 per diluted share, charge related to severance, facility closures and other one-

time costs; and a $2.6 million, or $0.02 per diluted share, one-time charge associated with incremental insurance reserves incurred as a result of a decision to increase our self-insurance deductibles to achieve a risk management structure typical for businesses of our combined company’s size and risk profile. Adjusted EBITDA⁽¹⁾ totaled ($11.4 million) for the third quarter of 2015. For the fourth quarter of 2014, net income was $22.3 million, or $0.40 per diluted share, on revenue of $483.5 million, and Adjusted Net Income⁽¹⁾ was $30.5 million, or $0.54 per diluted share⁽¹⁾, after excluding, on an after-tax basis, a $4.9 million, $0.08 per diluted share, charge related to costs associated with the Transaction; a $0.5 million, $0.01 per diluted share, charge related to an insurance settlement; and a $2.7 million tax effect, $0.05 per diluted share, from the enactment of the Tax Increase Prevention Act.

Founder, Chairman and Chief Executive Officer Josh Comstock commented, “The entire year was extremely challenging for the North American oilfield services industry as commodity prices continued to fall, causing severe reductions in drilling, completion and production activities. We entered the fourth quarter with a focus on upholding utilization and increasing market share for our core service lines in anticipation of the typical year-end seasonal slowdown. We were able to maintain revenue for our Completion Services segment quarter over quarter and experienced only a 10% sequential decline in revenue in our Well Support Services segment, which are impressive accomplishments given the impact of the seasonal slowdown and weather, compounded by further deterioration of market conditions as the rig count dropped approximately 13% over the course of the quarter. We achieved a noteworthy improvement in Adjusted EBITDA by generating strong utilization levels at the beginning of the quarter and exercising prudent management through the year-end slowdown. We surpassed the minimum bank EBITDA target for the fourth quarter required under our credit facility, which allowed us to carry forward the full $20.0 million cushion, resulting in a $40.0 million cushion basket available for the first quarter of 2016 as needed.

“In our Completion Services segment, we increased Adjusted EBITDA by $18.6 million sequentially on flat revenue through sound, thorough management of our business. I am proud of our Completions Services team for rising to the challenge and delivering solid quarterly results that outperformed many of our peers. We grew revenue and profitability in our hydraulic fracturing division by increasing utilization with higher margin work, stacking our least productive equipment and aggressively controlling costs. With respect to our coiled tubing operations, activity levels improved in October, but by mid-November we began to feel the effects of the seasonal slowdown, and several major customers eliminated or delayed previously scheduled work. Our wireline operations experienced decreasing activity levels and continued pricing pressure in most of our core basins, resulting in declining revenue throughout the quarter.

“In our Well Support Services segment, we worked diligently with our customers to maintain utilization in order to minimize the effect on revenue and profitability in the quarter. Overall utilization levels were higher in the beginning of the quarter, deteriorating over the latter half with the typical holiday slowdown. We experienced weakness in areas that are typically strong in the fourth quarter, such as Canada, primarily due to exceptionally low commodity prices. Even with seasonal revenue declines and difficult market conditions in the quarter, we increased Adjusted EBITDA margin for this segment by approximately 80 basis points, which is a testament to the effectiveness of our integration strategy, strength of our management team and commitment of our employees.

“Looking back on 2015 and the challenging headwinds that all of us in the oil and gas industry battled, I want to emphasize how proud and appreciative I am of all of our employees. Working tirelessly together, we successfully managed through what has been one of the most difficult operating environment for the oil and gas industry to date, while also combining two sizable entities into one of the largest North American oilfield completion and production services companies. We successfully completed the integration of Nabors’ completion and production services business ahead of schedule, which

Page 2 of 13

involved an extraordinary effort across our employee base to fully integrate the numerous systems and functions in a seamless and timely manner. Closing this transformative transaction during the early part of the downturn, we had the impetus to double-down on our efforts to streamline our combined company and to further improve our cost structure, leveraging our greater scale. We successfully achieved greater synergies than originally anticipated, and at an accelerated pace. Additionally, through our various research and technology initiatives we became more vertically integrated, which has enabled us to continue to reduce our cost structure, creating opportunities to drive revenue and gain market share. For example, we designed and are manufacturing in-house perforating guns, addressable switches and other expendable components for the perforating string used in our wireline operations at below market cost. We believe that this proprietary technology coupled with cost-effective manufacturing capability will enable us to maintain one of the lowest cost structures for wireline services in the industry and also presents sizeable third party sales potential. Additionally, through multiple field tests with 36 operators on 175 wells, we demonstrated that wells completed using our recently-introduced LateralScience engineered completions process consistently experience a better than average increase in production, which offers significant value to our customer’s bottom line. During 2015, we also introduced our proprietary, downhole directional drilling motor with significant value-add results to our customers. Our design has one of the highest torque ratings in the industry, which allows customers to rely on a single bottomhole assembly, thereby eliminating drilling days and substantially reducing costs. The outstanding performance of both our LateralScience technology and drilling motor are already drawing attention in the industry with increasing customer demand. These are just a few examples of how, through the efforts and dedication of the entire C&J team, we strategically expanded and strengthened our Company in the face of deteriorating conditions, and did so in a manner that enhances our ability to drive revenue, increase profitability and capture market share when the industry recovers.”

Results for the Three Months Ended December 31, 2015

Completion Services

Fourth quarter 2015 revenue from our Completion Services segment was $256.6 million, with Adjusted EBITDA⁽¹⁾ of $10.0 million, compared to revenue of $256.9 million and Adjusted EBITDA⁽¹⁾ of ($8.6 million) for the third quarter of 2015, and revenue of $472.9 million and Adjusted EBITDA⁽¹⁾ of $105.6 million for the fourth quarter of 2014.

Utilization levels for our Completion Services improved entering the fourth quarter, although we continued to experience significant pricing pressure throughout the quarter and activity declined with the typical year-end seasonal slowdown. Hydraulic fracturing activity was strong in October, but as we moved through the quarter and activity slowed, we strategically stacked additional equipment and focused on capturing higher overall utilization levels across our active equipment base. Our strategy, which included concentrating on key customers in core basins, aggressively managing our operational cost structure and stacking our lower utilized equipment, produced improved profitability despite the challenging headwinds we faced in the back half of the quarter. In our coiled tubing service line, utilization increased at the beginning of the quarter, but activity began to decline as the effects of the seasonal slowdown impacted our operations and customers delayed previously scheduled work. In our wireline service line, both pricing and utilization remained depressed and continued to weaken with the falling rig count, seasonal slowdown and inclement weather experienced during the course of the quarter.

As we entered the first quarter of 2016, our Completion Services segment experienced a significant decline in activity that has remained depressed. We are keeping a sharp focus on managing our operations and controlling costs, including closing additional facilities, further reducing headcount, stacking idle equipment and lowering our cost structure to ensure our

operations remain aligned with market conditions. The implementation of this strategy over the course of the fourth quarter enabled us to protect market share and deliver an approximate $18.6 million sequential improvement in Adjusted EBITDA for this segment. We will continue to focus on servicing the needs of our core customer base, and make the appropriate decisions as needed, to more effectively align our operations with current market conditions.

Well Support Services

Fourth quarter 2015 revenue from our Well Support Services segment was $135.7 million, with Adjusted EBITDA⁽¹⁾ of $22.3 million, compared to revenue of $150.9 million and Adjusted EBITDA⁽¹⁾ of $23.6 million for the third quarter of 2015.

Revenue from our Well Support Services segment was negatively impacted by the typical year-end slowdown and continued pricing pressure. Despite increased demand for our services in October, the seasonal slowdown around the holidays resulted in rigs being released in several core operating basins. We also encountered some weakness in areas that typically maintain strong fourth quarter activity, such as Canada, due to low commodity prices. During the quarter, we supported utilization and protected market share through pricing concessions, while repositioning equipment and resources in line with market conditions and customer demand. Despite declining revenue, our continued focus on restructuring this segment, enhancing efficiencies and aggressively reducing costs, allowed us to generate a sequential Adjusted EBITDA margin increase of approximately 80 basis points.

As with our Completion Services segment, activity and pricing levels for our Well Support Services segment declined and have remained depressed entering the first quarter of 2016. Our customers continue to focus on lowering their costs due to the continued weakness in commodity prices, and we will continue to work with them to the best of our ability to sustain utilization, protect market share and capitalize on strategic opportunities.

Other Services

Our Other Services segment includes our smaller service lines and divisions, such as cementing, equipment manufacturing and repair, specialty chemicals, directional drilling, artificial lift, Middle Eastern operations and research and technology (“R&T”). In addition, the Other Services segment includes costs associated with general corporate activities and intersegment eliminations.

Fourth quarter 2015 revenue from our Other Services segment was $16.7 million with Adjusted EBITDA⁽¹⁾ of ($24.6 million), compared to $19.7 million of revenue with Adjusted EBITDA⁽¹⁾ of ($26.4 million) for the third quarter of 2015, and $10.6 million of revenue with Adjusted EBITDA⁽¹⁾ of ($23.3 million) for the fourth quarter of 2014. Like our core services lines, the businesses comprising our Other Services segment were negatively impacted by the falling rig count and the typical year-end slowdown. In spite of declining activity levels, we were able to sequentially grow revenue within two of our most promising R&T initiatives: directional drilling and artificial lift applications. Additionally, in spite of a more than 15% reduction in revenue from this segment during the fourth quarter, Adjusted EBITDA increased approximately 7% as a result of our continued efforts to cut overhead costs and align our active R&T initiatives with current market conditions.

Other Financial Information

Our adjusted selling, general and administrative expense (“Adjusted SG&A”) for the fourth quarter of 2015 was $47.0 million, compared to $53.3 million for the third quarter of 2015 and $44.8 million for the fourth quarter of 2014 in each instance exclusive of costs associated primarily with the Transaction, severance costs and incremental insurance reserves. These excluded costs totaled $4.4 million for the fourth quarter of 2015, $7.7 million for the third quarter of 2015 and $8.3 million for the fourth quarter of 2014. The sequential decrease in Adjusted SG&A was driven by numerous cost control initiatives, including reductions in headcount and the closing of facilities following the completion of the Transaction.

Excluding one-time items, we incurred $3.4 million in research and development expense (“R&D”) for the fourth quarter of 2015, compared to $4.5 million for the third quarter of 2015 and $4.5 million for the fourth quarter of 2014. The approximate 26% sequential reduction of R&D expense was primarily driven by our continued cost control efforts, including our decision to delay certain R&T initiatives. We continue to invest in key technologies that we believe will provide our business with a competitive advantage by reducing our cost base for key inputs, enhancing our operational capabilities and generating operational efficiencies for our customers.

Depreciation and amortization expense (“D&A”) in the fourth quarter of 2015 was $82.7 million, compared to $74.7 million for the third quarter of 2015 and $32.4 million in the fourth quarter of 2014. The lower D&A expense in the third quarter was driven by the one-time true up of depreciation associated with adjustments to the estimated fair value and useful lives of PP&E for the acquired Nabors business.

Liquidity

As of December 31, 2015, we had $121.0 million drawn and $12.6 million of letters of credit outstanding under our recently amended revolving credit facility. Additionally, we had $1.1 billion outstanding under a Term Loan B facility, comprised of a $570.7 million term loan B-1 and a $481.4 million term loan B-2. At year-end, we had long-term capital lease obligations that totaled $32.0 million. Our long-term debt balance is net of $52.4 million of original issue discount on the Term Loan B facility.

Capital expenditures totaled $24.8 million during the fourth quarter of 2015, consistent with $24.2 million during the third quarter of 2015. During the second half of 2015, we limited capital expenditures to the maintenance of our existing equipment to extend its useful life. In 2016, we expect to spend $75 to $100 million for primarily the maintenance of our existing equipment. Since our 2016 capex budget depends on operational activity levels, if the current market weakness continues, we expect to spend at the bottom of the range.

Results for the Year Ended December 31, 2015

For the year ended December 31, 2015, we reported a net loss of ($872.5 million), or ($8.48) per diluted share, on revenue of $1.7 billion, compared to net income of $68.8 million, or $1.22 per diluted share, on revenue of $1.6 billion for the year ended December 31, 2014.

Adjusted Net Loss⁽¹⁾ for the year ended December 31, 2015 was ($191.0 million), or ($1.86) per diluted share⁽¹⁾. Adjusted Net Loss⁽¹⁾ excludes the following, net of tax: a $617.9 million, or $6.01 per diluted share, impairment charge; a $37.7 million, or $0.37 per diluted share, charge related to costs associated with the Transaction; a $23.2 million, or $0.23 per diluted share, inventory write-down; a $6.0 million, or $0.06 per diluted share, charge associated with customer

settlement/bad debt write-offs; a $4.4 million, or $0.04 per diluted share, charge for severance, facility closures and other one-time costs; and a $2.3 million, or $0.02 per diluted share, one-time charge associated with incremental insurance reserves incurred as a result of a decision to increase our self-insurance deductibles to achieve a risk management structure typical for businesses of our combined company’s size and risk profile; offset by a $9.8 million, or $0.10 per diluted share, immaterial out-of-period adjustment.

For the year ended December 31, 2015, we reported Adjusted EBITDA⁽¹⁾ of $46.8 million, compared to Adjusted EBITDA⁽¹⁾ of $252.9 million for the year ended December 31, 2014.
