Introductory Note

As previously announced, on August 21, 2023, Permian Resources Corporation, a Delaware corporation (“Permian Resources” or the “Company”), Smits Merger Sub I Inc., a Delaware corporation and a direct wholly owned subsidiary of the Company (“Merger Sub I”), Smits Merger Sub II LLC, a Delaware limited liability company and a direct wholly owned subsidiary of the Company (“Merger Sub II”), and Permian Resources Operating, LLC, a Delaware limited liability company (“PR OpCo”), entered into that certain Agreement and Plan of Merger (the “Merger Agreement”) with Earthstone Energy, Inc., a Delaware corporation (“Earthstone”), and Earthstone Energy Holdings, LLC, a Delaware limited liability company (“ESTE OpCo”). The Merger Agreement provides that, among other things and subject to the terms and conditions of the Merger Agreement, (i) Merger Sub I will be merged with and into Earthstone (the “Initial Company Merger”), with Earthstone surviving the Initial Company Merger as a wholly owned subsidiary of the Company (the “Initial Surviving Corporation”), (ii) following the Initial Company Merger, the Initial Surviving Corporation will be merged with and into Merger Sub II (the “Subsequent Company Merger” and, together with the Initial Company Merger, the “Company Mergers”), with Merger Sub II surviving the Subsequent Company Merger as a wholly owned subsidiary of the Company (in such capacity, the “Surviving Company”), and (iii) following the Company Mergers, ESTE OpCo will be merged with and into PR OpCo (the “OpCo Merger” and, collectively with the Company Mergers, the “Mergers”), with PR OpCo surviving the OpCo Merger. The Mergers and the other transactions contemplated by the Merger Agreement are herein referred to as the “Transactions.”

Directors

On October 30, 2023, the board of directors of the Company (the “Board”) approved, in accordance with the terms of the Merger Agreement, increasing the size of the Board to consist of 11 members, effective as of closing of the Transactions. On October 30, 2023, in connection with the Transactions, Matthew G. Hyde resigned from the Board, effective as of closing of the Transactions. At the time of his resignation, Mr. Hyde served as chair of the Nominating, Environmental, Social and Governance Committee (the “NESG Committee”) and as a member of the Compensation Committee. The resignation of Mr. Hyde was not a result of any disagreement with the Company.

On October 30, 2023, the Board appointed Robert J. Anderson and Frost W. Cochran to the Board, effective as of closing of the Transactions. Messrs. Anderson and Cochran previously served on the board of directors of Earthstone. Biographical information for Messrs. Anderson and Cochran is set forth in Earthstone’s Definitive Proxy Statement filed with the Securities and Exchange Commission (the “SEC”) on April 27, 2023, which information is incorporated herein by reference.

Neither of Messrs. Anderson or Cochran are related to any officer or director of the Company. With respect to each of Messrs. Anderson and Cochran, there are no arrangements or understandings between such director and any other persons pursuant to which he will serve as a director, other than the Merger Agreement.

Independence of Directors

The Board has determined that each of Messrs. Anderson and Cochran are independent within the meaning of the listing rules of the New York Stock Exchange (“NYSE”) and the rules and regulations of the SEC.

In addition, the Board has determined that Robert M. Tichio, an existing member of the Board, is independent within the meaning of the listing rules of the NYSE and the rules and regulations of the SEC.

Committees of the Board

On October 30, 2023, the Board approved the formation of two new committees of the Board to replace the current NESG Committee – the Nominating and Corporate Governance Committee and the Environmental, Social and Governance Committee – and appointed the following directors to serve on the committees of the Board, in each case effective as of closing of the Transactions:

Audit Committee: Jeffrey H. Tepper (Chair), Maire A. Baldwin, Karan E. Eves and Frost W. Cochran;

Compensation Committee: Maire A. Baldwin (Chair), Steven D. Gray, Robert M. Tichio and Robert J. Anderson;

Nominating and Corporate Governance Committee: Steven D. Gray (Chair), Jeffrey H. Tepper, Aron Marquez and Karan E. Eves; and

Environmental, Social and Governance Committee: Robert M. Tichio (Chair), Aron Marquez, Robert J. Anderson and Frost W. Cochran.

At the Special Meeting of the Company held on October 30, 2023 (the “Special Meeting”), in connection with the previously announced Mergers, the stockholders of the Company voted as set forth below on the following proposals. Each proposal voted on at the Special Meeting is described in detail in the Company’s joint proxy statement/prospectus filed with the SEC on September 26, 2023 and mailed to the Company’s stockholders on or about September 26, 2023.

As of the close of business on September 20, 2023, the record date for the Special Meeting, there were approximately 328,795,305 shares of the Company’s Class A common stock, par value $0.0001 per share (“Class A Common Stock”), and 243,075,559 shares of the Company’s Class C common stock, par value $0.0001 per share (“Class C Common Stock” and, together with the Class A Common Stock, the “Common Stock”), issued and entitled to vote at the Special Meeting. Each share of Common Stock was entitled to one vote with respect to each proposal. A total of 505,086,316 shares of Common Stock, representing approximately 88.3% of the outstanding shares of Common Stock entitled to vote at the Special Meeting, were present in person or by proxy, constituting a quorum.

The final voting results for the proposals voted on at the Special Meeting are set forth below:

1. The Permian Resources Stock Issuance Proposal - to approve the issuance of shares of Common Stock to stockholders of Earthstone, in connection with the transactions pursuant to the terms of the Merger Agreement.

2. The Adjournment Proposal - to approve the adjournment of the Special Meeting to solicit additional proxies if there are not sufficient votes at the time of the Special Meeting to approve the Permian Resources Stock Issuance Proposal. This proposal was rendered moot as the Permian Resources Stock Issuance Proposal was approved by the requisite number of shares voted at the Special Meeting.

Subject to the satisfaction of other customary closing conditions, the Company expects the Transactions to close on or around November 1, 2023 and will release more information about the combined company at that time.

Forward-Looking Statements and Cautionary Statements

Statements regarding closing of the Mergers are “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended. Such forward-looking statements are subject to a number of risks and uncertainties that could cause actual results to differ materially from the forward-looking statements. These include the timing, receipt and terms and conditions of any required governmental and regulatory approvals of the Mergers or other circumstances that could give rise to the termination of the Merger Agreement, and the risk that the parties may not be able to satisfy the conditions to the Mergers in a timely manner or at all. All such factors are difficult to predict and are beyond Permian Resources’ control.
