Except for historical information contained herein, the statements in this presentation are forward-looking statements that are made pursuant to the Safe Harbor Provisions of the Private Securities Litigation Reform Act of 1995. Forward-looking statements and the business prospects of Pioneer are subject to a number of risks and uncertainties that may cause Pioneer's actual results in future periods to differ materially from the forward-looking statements.

These risks and uncertainties include, among other things, volatility of commodity prices, product supply and demand, the impact of a widespread outbreak of an illness, such as the COVID- 19 pandemic, on global and U.S. economic activity, competition, the ability to obtain environmental and other permits and the timing thereof, other government regulation or action, the ability to obtain approvals from third parties and negotiate agreements with third parties on mutually acceptable terms, litigation, the costs and results of drilling and operations, availability of equipment, services, resources and personnel required to perform the Company's drilling and operating activities, access to and availability of transportation, processing, fractionation, refining, storage and export facilities, Pioneer's ability to replace reserves, implement its business plans or complete its development activities as scheduled, access to and cost of capital, the financial strength of counterparties to Pioneer's credit facility, investment instruments and derivative contracts and purchasers of Pioneer's oil, natural gas liquid and gas production, uncertainties about estimates of reserves and resource potential, identification of drilling locations and the ability to add proved reserves in the future, the assumptions underlying forecasts, including forecasts of production, cash flow, well costs, capital expenditures, rates of return to shareholders, expenses, cash flows from purchases and sales of oil and gas net of firm transportation commitments, sources of funding and tax rates, quality of technical data, environmental and weather risks, including the possible impacts of climate change, cybersecurity risks, ability to implement stock repurchases, the risks associated with the ownership and operation of the Company's oilfield services businesses and acts of war or terrorism. These and other risks are described in Pioneer's Annual Report on Form 10-K for the year ended December 31, 2019, Quarterly Report on Form 10-Q for the quarter ended March 31, 2020, and other filings with the Securities and Exchange Commission. In addition, Pioneer may be subject to currently unforeseen risks that may have a materially adverse impact on it.

Additionally, the information in this presentation contains forward-looking statements related to the recently announced merger transaction between the Company and Parsley Energy, Inc. ("Parsley"). Such forward-looking statements are subject to risks and uncertainties that are difficult to predict and, in many cases, beyond the Company's control. These risks and uncertainties include, among other things, the risk that the businesses of Pioneer and Parsley will not be integrated successfully; the cost savings, synergies and growth from the proposed transaction may not be fully realized or may take longer to realize than expected; management time may be diverted on transaction-related issues; the potential adverse effect of future regulatory or legislative actions on Pioneer and Parsley or the industries in which they operate, including the risk of new restrictions with respect to development activities on Pioneer's or Parsley's assets; the credit ratings of the combined company or its subsidiaries may be different from what Pioneer expects; governmental and regulatory approvals required for the proposed transaction may not be able to be obtained, or may delay the proposed transaction, result in the imposition of conditions that could reduce its anticipated benefits, or cause the parties to abandon the transaction; a condition to closing of the proposed transaction may not be satisfied; the length of time necessary to consummate the proposed transaction may be longer than anticipated for various reasons; potential liability resulting from pending or future litigation related to the proposed transaction; the potential impact of the announcement or consummation of the proposed transaction on relationships with customers, suppliers, and competitors; and transaction costs may be higher than anticipated.

Accordingly, no assurances can be given that the actual events and results will not be materially different than the anticipated results described in the forward-looking statements. Pioneer undertakes no duty to publicly update these statements except as required by law. Please see the supplemental slides included in this presentation for other important information.
