Explanation of Responses:

( 1 )On October 27, 2023, the Issuer used a portion of the net proceeds from the closing of its initial public offering ("IPO") of common units to purchase common units from certain of the Issuer's pre-IPO unitholders, including the Reporting Person, at a price of $17.67 per unit (such price per unit being the price that the Issuer received from the underwriters in the IPO, net of the underwriting discounts and commissions). ( 2 )The Reporting Person is the Trustee of the Tom L. Ward 1992 Revocable Trust (the "Trust"). By virtue of the relationship, the Reporting Person may be deemed to have or share beneficial ownership of the securities held of record by the Trust, but the Reporting Person disclaims any beneficial ownership of the reported securities other than to the extent of any pecuniary interest he may have therein, directly or indirectly. ( 3 )The Reporting Person exercises control over Mach Resources LLC ("Mach Resources"). Mach Resources is owned 50.5% by Tom L. Ward through the Trust and 49.5% by WCT Resources LLC which is owned by certain trusts affiliated with Mr. Ward for which an employee of Mach Resources is trustee. By virtue of the relationship, the Reporting Person may be deemed to have or share beneficial ownership of the securities held of record by Mach Resources, but the Reporting Person disclaims any beneficial ownership of the reported securities other than to the extent of any pecuniary interest he may have therein, directly or indirectly. ( 4 )The reported securities represent phantom units. Each phantom unit represents the contingent right to receive one common unit of the Issuer upon vesting. The phantom units will vest in three equal installments on each of the first three anniversaries of the grant date, subject in each case to the continued service through such dates.

Remarks: The Reporting Person is Chief Executive Officer of Mach Natural Resources GP LLC, the general partner of the Issuer (the "General Partner"). The Issuer is managed by the directors and executive officers of the General Partner.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
