        <footnote id="F1">Represents the number of shares required to be sold by the reporting person to cover tax withholding obligations in connection with the vesting of the performance restricted stock units.  The sales were effected through a mandatory &quot;sell to cover&quot; transaction that did not represent a discretionary trade by the reporting person.</footnote>
        <footnote id="F2">The price reported in Column 4 is a weighted average price. These shares were sold in multiple transactions at prices ranging from $13.49 to $14.38, inclusive. The reporting person undertakes to provide to the Registrant (as defined below), any security holder of the Registrant, or staff of the U.S. Securities and Exchange Commission (the &quot;SEC&quot;), upon request, full information regarding the number of shares sold at each separate price within the range set forth in this footnote.</footnote>
        <footnote id="F3">The price reported in Column 4 is a weighted average price. These shares were sold in multiple transactions at prices ranging from $13.48 to $13.88, inclusive. The reporting person undertakes to provide to the Registrant (as defined below), any security holder of the Registrant, or staff of the U.S. Securities and Exchange Commission (the &quot;SEC&quot;), upon request, full information regarding the number of shares sold at each separate price within the range set forth in this footnote.</footnote>
        <footnote id="F4">On January 7, 2026, pursuant to a corporate reorganization, Permian Resources Corporation (formerly known as PRC NewCo Inc) (the Registrant) became the successor of Permian Resources Holdings Inc. (formerly known as Permian Resources Corporation) (the Predecessor Registrant) following the merger of a subsidiary of the Registrant with and into the Predecessor Registrant (the Merger).  The Merger resulted in (i) the Registrant becoming the parent of the Predecessor Registrant and (ii) the former security holders of the Predecessor Registrant owning, as of the effective time of the Merger (the Merger Effective Time), economic interests in the Registrant identical to and in the same proportions as the economic interests they held in the Predecessor Registrant immediately prior to the Merger Effective Time.</footnote>
        <footnote id="F5">Immediately following the Merger Effective Time, the reporting person contributed all of such reporting person's common units representing limited liability company interests (OpCo Units) in Permian Resources Operating, LLC (OpCo) to the Registrant in exchange for newly issued shares of Class A Common Stock, par value $0.0001 per share, of the Registrant, on a one for one basis (the OpCo Unit Exchange). Immediately prior to the Merger Effective Time, all of the shares of Class C Common Stock, par value $0.0001 per share, of the Predecessor Registrant held by the reporting person were surrendered and cancelled for no consideration.</footnote>
        <footnote id="F6">Prior to the OpCo Unit Exchange, the reporting person had a redemption right pursuant to the Seventh Amended and Restated Limited Liability Company Agreement of OpCo, pursuant to which each OpCo Unit held by the reporting person could be exchanged at such reporting person's election for a newly issued share of Class A Common Stock, par value $0.0001 per share, of the Predecessor Registrant (along with the cancellation of the corresponding share of Class C Common Stock, par value $0.0001 per share, of the Predecessor Registrant). The OpCo Units did not have an expiration date.</footnote>
