This Amendment No. 6 (this "Amendment") amends the Schedule 13D filed with the Securities and Exchange Commission (the "SEC") on April 4, 2019 (the "Original Schedule 13D"), as amended by Amendment No. 1 filed on April 1, 2022 ("Amendment No. 1"), as further amended by Amendment No. 2 filed on July 29, 2022 ("Amendment No. 2"), as further amended by Amendment No. 3 filed on October 26, 2022 ("Amendment No. 3"), as further amended by Amendment No. 4 filed on May 19, 2023 ("Amendment No. 4") and as further amended by Amendment No. 5 filed on March 9, 2026 ("Amendment No. 5" and, together with the Original Schedule 13D, as so amended, the "Schedule 13D"). As disclosed herein, EnCap Partners GP is no longer the beneficial owner of more than 5% of the Common Units and the Reporting Persons are filing this Schedule 13D as an exit filing.

**Item 5. Interest in Securities of the Issuer**

**(a)**
The aggregate number and percentage of Common Units beneficially owned by each Reporting Person is set forth in Items 7, 8, 9, 10, 11 and 13 of the cover pages to this Schedule 13D relating to such Reporting Person and is incorporated by reference into this Item 5.

**(b)**
For purposes of Rule 13d-3 promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), EnCap Partners GP, through its direct and indirect ownership and management of MB Minerals, Sabalo Midland Basin, EnCap Legacy Fund VIII and EnCap Fund IX, may be deemed to share the right to direct the vote or the disposition of the Common Units and OpCo Common Units (and an equal number of Class B Units) held of record by EnCap Legacy Fund VIII and MB Minerals, respectively, and thus, for the purposes of Rule 13d-3 promulgated under the Exchange Act, may be deemed to beneficially own the Common Units and OpCo Common Units (and an equal number of Class B Units) held by EnCap Legacy Fund VIII and MB Minerals, respectively. The Securities held by the EnCap Entities represent approximately 4.93% of the outstanding Common Units (calculated based on an assumed combined 99,559,213 Common Units outstanding, which consists of (a) a total of 94,189,995 Common Units, based on 793,507 Common Units issued to directors and officers of the Issuer on February 24, 2026, and 93,396,488 Common Units outstanding as of February 20, 2026, as reported by the Issuer in its Annual Report and (b) assumes that all 5,369,218 Class B Units directly held by MB Minerals as of February 20, 2026 (along with an equivalent number of OpCo Common Units, but no other of the Class B Units or OpCo Common Units) were exchanged for newly-issued Common Units on a one-for-one basis).

**(c)**
Except as set forth in this Schedule 13D, none of the Reporting Persons or, to their knowledge, any of its directors, executive officers or other control persons named on Schedule A, Schedule B, Schedule C or Schedule D attached hereto, has effected any transaction in the Common Units during the past 60 days.
