Last month, I informed you of a ruling made by the Delaware Court of Chancery which required C&J Energy Services to solicit alternative proposals from other potential buyers to purchase or acquire a controlling stake in C&J. We and C&J acted swiftly and immediately appealed the ruling.

I am pleased to share that the Delaware Supreme Court overturned this ruling on Friday, confirming C&J’s position that its Board of Directors and management team acted with due diligence in negotiating the deal with Nabors. This is a positive step forward in clearing the way for closing the pending transaction.

In response to the ruling, C&J’s Founder, Chairman and Chief Executive Officer Josh Comstock said, “C&J has been and will continue to be dedicated to upholding the highest governance standards, and we believe that our Board, management and legal teams negotiated a precedent-setting transaction in accordance with Delaware law and at all times acting in the best interest of our stockholders.”

In a press release issued by C&J, Comstock also said, “We continue to believe firmly that the transaction with Nabors creates a diversified completion and production services provider and will create significant stockholder value. We, therefore, remain focused on closing the transaction as soon as possible. We look forward to integrating our operations as soon as possible and working with our new employees to realize the many benefits offered by this transformative transaction.”

Attached below please find the press release and internal memo sent to all C&J employees following yesterday’s victory. I was asked to share this important message with all NCPS and NPS employees. Please take a moment to read the memo which outlines next steps in the transaction process.

Similar to C&J, Nabors has a longstanding commitment to comply with the law wherever we operate, and to conduct our business with the highest ethical standards. I am very pleased with yesterday’s ruling which confirms both companies negotiated the transaction with the highest levels of responsibility, integrity and legal compliance.

Until the deal is closed by the end of January, please remain focused on delivering the highest level of performance to our customers. Please remember that no one should answer any media inquiries or give any commentary about this transaction to any member of the media. All media inquires should be directed to Denny Smith in Corporate Development or Kim Hoover in Corporate Communications.

As we enter 2015, I would like to take the opportunity to wish you and your family a happy, healthy and, above all, safe holiday season.

Thank you again for your hard work and continued dedication to Nabors.

(“C&J” or the “Company”) (NYSE: CJES) today announced the Delaware Supreme Court has ruled to overturn a bench ruling and order of the Delaware Court of Chancery dated November 24 and 25, 2014, respectively, which had required the Company to solicit alternative proposals to purchase the Company (or a controlling stake in the Company) from other potential buyers for a period of 30 days before holding its stockholder meeting to approve the merger agreement with Nabors Industries Ltd. The Delaware Supreme Court found that the Company had pursued its proposed transaction with Nabors in compliance with the Company’s fiduciary duties toward all of its stockholders.

C&J ENERGY SERVICES MEMO TO EMPLOYEES

December 19, 2014

Dear C&J Energy Services Employees,

I am pleased to update you on an important development related to C&J Energy Services’ pending transaction with Nabors to acquire their completion and production services business. As I know you are aware, in late November the Delaware Court of Chancery issued a ruling that required us to solicit alternative proposals from other potential partners before we could close the pending transaction with Nabors. C&J is committed to the highest standards of governance, so while we disagreed with the Delaware Court’s decision and appealed it to the Delaware Supreme Court, we simultaneously complied with the lower court’s order.

As you may have heard, today we received the great news that the Delaware Supreme Court overturned the ruling of the lower court, which further confirmed our belief that our Board, management and legal teams complied with their duties and negotiated a precedent setting transaction in accordance with Delaware law and at all times acted in the best interest of our stockholders. Attached to this email is a copy of the press release that we issued this afternoon announcing the Delaware Supreme Court’s ruling in our favor. As a result of this ruling, we immediately terminated the solicitation process and we are moving strongly forward to the closing of this transaction. I continue to believe that this transaction will deliver significant value to our stockholders, customers and employees. While hurdles are to be expected during transactions of this size and complexity, the Delaware Supreme Court’s ruling today confirmed our confidence in our course of action.

Integrity and fair dealing are fundamental to the way we do business. We are committed to upholding the highest governance and ethical standards — and we take our duties and responsibilities to our stockholders, our customers and our employees seriously. Throughout this entire process, our board and management team worked hard to ensure that we acted in the most ethical and responsible way and fulfilled our duties to our stockholders. We have an exceptional team and there are many people who deserve recognition for their hard work and getting us to this point. Foremost are our dedicated employees. You have remained strong and focused on the task at hand, which I believe to be a great testament to the C&J culture. I also specifically would like to thank our legal team, who successfully managed this precedent-setting, complex transaction while ensuring we complied with Delaware law and stayed true to the highest of standards. Finally, I am grateful to our Board of Directors, for their commitment to our Company and our stockholders and for all of the support and encouragement they have extended to me and our management team throughout this process. I am so proud of our Company and of all of you, and I am honored by the trust you have put in me. I am confident that together we can take C&J to greater heights.

As a general update, we are still working through the standard SEC review process, which we hope to have completed by the end of the year. We are moving forward with the goal of closing this transaction by the end of January 2015 and we are eager to begin integrating our companies. As we continue to work towards closing this transaction, we will communicate with you to keep you informed when and where we can, as appropriate. Any calls you receive from the media, should be directed to Danielle Foley (713-325-6090) or John Fitzpatrick (713-325-6082). Please do not answer any questions or give any commentary about this transaction to any member of the media.

As we head into the Holiday Season and look towards the New Year, it is wonderful to be able to share this news with you all before Christmas. We are one step closer to closing the transaction with Nabors and welcoming their employees into our C&J family. I wish everyone a happy holiday and a happy and healthy New Year. I look forward to the continued advancement of C&J and working with all of you on what is sure to be an exciting 2015. Thank you again for all of your hard work and dedication. We couldn’t do this without you.

Regards,

Josh
