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. BCE-Mach Aggregator LLC is indirectly managed by Bayou City Energy Management LLC ("BCEM"). William W. McMullen is the Managing Partner of BCEM. Each of BCEM and Mr. McMullen (by virtue of his relationship with BCEM) may be deemed to indirectly beneficially own (as that term is defined in Rule 13d-3 under the Act) the common units which BCE-Mach Aggregator LLC beneficially owns. Mr. McMullen disclaims beneficial ownership of such common units except to the extent of his pecuniary interest therein.
Remarks:
The Reporting Person is a Director 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.
