Dear Concho Employees: This morning we announced that Concho will acquire RSP Permian, Inc. in an all-stock transaction. We are excited about this transaction with RSP, which has highly complementary assets that enhance our scale advantage and reinforce our leadership position in the Permian. As you may know, RSP like Concho is a Permian-focused operator with big, blocky acreage in the core of the Midland and Delaware Basins. RSP has an exceptional, high-margin asset portfolio and it has been executing a strategy of maximizing well performance and returns that provides opportunities for continuous development with large-scale projects. This is a natural fit for Concho. Together, our scale will nearly be unmatched in the Permian. Combined, we will be the largest Permian producer and we will run the largest drilling and completion program in the Permian with a combined position that will span more than 640,000 acres. We see opportunities to increase long-lateral development, direct capital to high-return multi-well projects and utilize shared infrastructure systems. With RSP, Concho will be an even stronger company, even better-positioned for continued growth and value creation.

Importantly, RSP shares our culture, our vision, and our focus on operating safely and efficiently. Our teams have long known and respected each other. We look forward to welcoming RSP employees to the Concho team. We expect to complete the transaction in the third quarter of 2018, subject to the approval of Concho and RSP shareholders, certain regulatory approvals and other customary closing conditions. Importantly, until the closing of this transaction, Concho and RSP will continue to operate as independent companies. Following the closing, Concho will continue to be headquartered in Midland and led by our existing management team. You can learn more about the deal and what it means for Concho by reading our press release, presentation and listening to the replay of our conversation with investors. These materials are available on our website. Additionally, there will be a Concho employee meeting in Midland this afternoon at 4:00 PM to discuss the details of this acquisition. This transaction will likely generate some interest by the media and other third parties, and it is important for us to speak with one voice. Please follow our company policy and direct all media inquiries to Megan Hays, Vice President of Investor Relations and Public Affairs. The deal we announced today makes me even more energized about our future and I appreciate the opportunity to continue to lead you through this next phase of growth for Concho. On behalf of our Board and senior management team, we thank you for your continued hard work. Sincerely, Tim Leach Chairman and Chief Executive Officer

FORWARD-LOOKING STATEMENTS AND CAUTIONARY STATEMENTS The foregoing contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. All statements, other than statements of historical fact, included in this communication that address activities, events or developments that Concho or RSP expects, believes or anticipates will or may occur in the future are forward-looking statements. Words such as “estimate,” “project,” “predict,” “believe,” “expect,” “anticipate,” “potential,” “create,” “intend,” “could,” “may,” “foresee,” “plan,” “will,” “guidance,” “look,” “outlook,” “goal,” “future,” “assume,” “forecast,” “build,” “focus,” “work,” “continue” or the negative of such terms or other variations thereof and words and terms of similar substance used in connection with any discussion of future plans, actions, or events identify forward-looking statements. However, the absence of these words does not mean that the statements are not forward-looking. These forward-looking statements include, but are not limited to, statements regarding the Transaction, pro forma descriptions of the combined company and its operations, integration and transition plans, synergies, opportunities and anticipated future performance. There are a number of risks and uncertainties that could cause actual results to differ materially from the forward-looking statements included in this communication. These include the expected timing and likelihood of completion of the Transaction, including the timing, receipt and terms and conditions of any required governmental and regulatory approvals of the Transaction that could reduce anticipated benefits or cause the parties to abandon the Transaction, the ability to successfully integrate the businesses, the occurrence of any event, change or other circumstances that could give rise to the termination of the merger agreement, the possibility that stockholders of Concho may not approve the issuance of new shares of common stock in the Transaction or that stockholders of RSP may not approve the merger agreement, the risk that the parties may not be able to satisfy the conditions to the Transaction in a timely manner or at all, risks related to disruption of management time from ongoing business operations due to the Transaction, the risk that any announcements relating to the Transaction could have adverse effects on the market price of Concho’s common stock or RSP’s common stock, the risk that the Transaction and its announcement could have an adverse effect on the ability of Concho and RSP to retain customers and retain and hire key personnel and maintain relationships with their suppliers and customers and on their operating results and businesses generally, the risk the pending Transaction could distract management of both entities and they will incur substantial costs, the risk that problems may arise in successfully integrating the businesses of the companies, which may result in the combined company not operating as effectively and efficiently as expected, the risk that the combined company may be unable to achieve synergies or it may take longer than expected to achieve those synergies and other important factors that could cause actual results to differ materially

from those projected. All such factors are difficult to predict and are beyond Concho’s or RSP’s control, including those detailed in Concho’s annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K that are available on its website at http://www.concho.com and on the SEC’s website at http://www.sec.gov, and those detailed in RSP’s annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K that are available on RSP’s website at http://www.rsppermian.com and on the SEC’s website at http://www.sec.gov. All forward-looking statements are based on assumptions that Concho or RSP believe to be reasonable but that may not prove to be accurate. Any forward-looking statement speaks only as of the date on which such statement is made, and Concho and RSP undertake no obligation to correct or update any forward-looking statement, whether as a result of new information, future events or otherwise, except as required by applicable law. Readers are cautioned not to place undue reliance on these forward-looking statements that speak only as of the date hereof. CAUTIONARY STATEMENTS REGARDING RESOURCE Concho may use the term “resource potential” and similar phrases to describe estimates of potentially recoverable hydrocarbons that SEC rules prohibit from being included in filings with the SEC. These are based on analogy to Concho’s existing models applied to additional acres, additional zones and tighter spacing and are Concho’s internal estimates of hydrocarbon quantities that may be potentially discovered through exploratory drilling or recovered with additional drilling or recovery techniques. These quantities may not constitute “reserves” within the meaning of the Society of Petroleum Engineer’s Petroleum Resource Management System or SEC rules. Such estimates and identified drilling locations have not been fully risked by Concho management and are inherently more speculative than proved reserves estimates. Actual locations drilled and quantities that may be ultimately recovered from Concho’s interests could differ substantially from these estimates. There is no commitment by Concho to drill all of the drilling locations that have been attributed to these quantities. Factors affecting ultimate recovery include the scope of Concho’s ongoing drilling program, which will be directly affected by the availability of capital, drilling and production costs, availability of drilling services and equipment, drilling results, lease expirations, transportation constraints, regulatory approvals, actual drilling results, including geological and mechanical factors affecting recovery rates, and other factors. Such estimates may change significantly as development of Concho’s oil and natural gas assets provide additional data. Concho’s production forecasts and expectations for future periods are dependent upon many assumptions, including estimates of production decline rates from existing wells and the undertaking and outcome of future drilling activity, which may be affected by significant commodity price declines or drilling cost increases or other factors that are beyond Concho’s control. Concho’s use of the term “premium resource” refers to assets with the capacity to produce at an internal rate of return that is greater than thirty-five percent based on fifty-five dollar oil and three dollar gas.
