Item 2.01

As discussed in the Introductory Note, on January 12, 2021, the Mergers were consummated in accordance with the terms of the Merger Agreement. In connection with the consummation of the Mergers, among other things, each share of Class A common stock, par value $0.01 per share, of the Company (the “Parsley Class A Common Stock”) issued and outstanding immediately prior to the effective time of the First Company Merger (the “Effective Time”) (other than shares of Parsley Class A Common Stock held in the treasury of the Company or owned, directly or indirectly, by Pioneer or Merger Sub Inc. immediately prior to the Effective Time and any unvested restricted shares of Parsley Class A Common Stock that did not vest by their terms as a result of the consummation of the Mergers) was at the Effective Time converted into and became exchangeable for 0.1252 (the “Exchange Ratio”) shares of common stock, par value $0.01 per share, of Pioneer (the “Pioneer Common Stock”).

Additionally, at the Effective Time, each membership interest unit of Opco LLC (each, an “Opco LLC Unit”) issued and outstanding immediately prior to the Effective Time (other than any Opco LLC Unit owned, directly or indirectly, by the Company or Pioneer or any of their respective subsidiaries immediately prior to the Effective Time), and all rights in respect thereof, were converted into the right to receive a number of shares of Pioneer Common Stock equal to the Exchange Ratio. At the Effective Time, each share of Class B common stock, par value $0.01 per share, of the Company (the “Parsley Class B Common Stock” and, together with the Parsley Class A Common Stock, the “Parsley Common Stock”) was automatically cancelled for no additional consideration, subject to any statutory rights to appraisal pursuant to the General Corporation Law of the State of Delaware with respect to, and only with respect to, such shares of Parsley Class B Common Stock.

~~Without~~Proposal ~~Pioneer~~2 ~~expected~~– ~~synergies.~~Compensation ~~Using~~Proposal discount rates ranging from 7.5% to 8.5%, reflecting estimates of Parsley’s weighted average cost of capital, Goldman Sachs discounted to present value as of September 30, 2020 (i) estimates of the unlevered free cash flows to be generated by Parsley on a standalone basis, excluding Pioneer expected synergies, for the period from September 30, 2020 to December 31, 2024, as reflected in the Pioneer projections (without synergies) for Parsley, and (ii) a range of illustrative terminal values for Parsley as of December 31, 2024, calculated by applying perpetuity growth rates ranging from (0.5)% to 0.5% to the estimate of the terminal year unlevered free cash flow of Parsley of approximately $785 million, as reflected in the Pioneer projections for Parsley (which analysis implied multiples of the implied terminal values derived for Parsley to estimated earnings before interest, taxes, depreciation, and amortization (“EBITDA”) for Parsley, as reflected in the Pioneer projections for Parsley, for 2024, ranging from 6.2x to 8.0x). Goldman Sachs derived the discount rates referenced above by application of the capital asset pricing model (“CAPM”), which requires certain company-specific inputs, including the company’s target capital structure weightings, the cost of long-term debt, future applicable marginal cash tax rate and a beta for the company, as well as certain financial metrics for the United States financial markets generally. The range of perpetuity growth rates was estimated by Goldman Sachs utilizing its professional judgment and experience, taking into account the Pioneer projections for Parsley on a standalone basis and market expectations regarding long-term real growth of gross domestic product and inflation. Goldman Sachs derived a range of illustrative enterprise values for Parsley by adding the ranges of present values it derived as described above. Goldman Sachs then subtracted from the range of illustrative enterprise values it derived the net debt of Parsley as of September 30, 2020 of approximately $3.161 billion, as reflected in Parsley’s consolidated balance sheet as of that date, and the TRA payment, to derive a range of illustrative equity values for Parsley. Goldman Sachs then divided the range of illustrative equity values it derived for Parsley on a standalone basis by the fully diluted shares of Parsley Class A common stock (including shares issuable in exchange for outstanding Parsley LLC stapled units) outstanding as of October 19, 2020 of 416,532,582, calculated based on equity information provided by Parsley management and approved for Goldman Sachs’ use by Pioneer management, to derive a range of illustrative present values per share of Parsley Class A common stock and Parsley LLC stapled unit of $13.88 to $19.29.

Morgan Stanley calculated a terminal value range of $16,451 million to $23,763 million for Pioneer by applying an exit multiple range of 4.5x to 6.5x to the EBITDA of Pioneer for the terminal year, based on Morgan Stanley’s professional judgement and taking into account Pioneer’s historical trading multiples.

All statements, other than statements of historical fact, included in this communication that address activities, events or developments that Pioneer or Parsley 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 Pioneer may not approve the issuance of new shares of common stock in the Transaction or that stockholders of Parsley 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 Pioneer’s common stock or Parsley’s common stock, the risk that the Transaction and its announcement could have an adverse effect on the ability of Parsley and Pioneer 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, the impact of reduced demand for Pioneer’s or Parsley’s products and products made from them due to governmental and societal actions taken in response to the COVID-19 pandemic; the uncertainties, costs and risks involved in Pioneer’s and Parsley’s operations, including as a result of employee misconduct; natural disasters, pandemics, epidemics (including COVID-19 and any escalation or worsening thereof) or other public health conditions 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 Pioneer’s or Parsley’s control, including those detailed in Pioneer’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.investors.pxd.com and on the SEC’s website at http://www.sec.gov, and those detailed in Parsley’s annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K that are available on Parsley’s website http://www.parsleyenergy.com and on the SEC’s website at http://www.sec.gov. All forward-looking statements are based on assumptions that Pioneer or Parsley 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 Parsley and Pioneer 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.
