Item 1.01. Entry into a Material Definitive Agreement.

On February 24, 2026, PrimeEnergy Resources Corporation (the “Company”), as borrower, entered into a Fifth Amendment (the “Amendment”) to its Fourth Amended and Restated Credit Agreement, dated as of July 5, 2022 (as previously amended, the “Credit Agreement”), with Citibank, N.A., as administrative agent, and the lenders party thereto.

The Amendment modifies certain terms of the Company’s senior secured revolving credit facility and constitutes the scheduled borrowing base redetermination under the Credit Agreement. Effective as of February 24, 2026, the borrowing base was reaffirmed at $115.0 million.

Among other things, the Amendment:

●	Reduces the applicable margin by 50 basis points at each utilization level. The SOFR loan margin now ranges from 2.75% to 3.75% (previously 3.25% to 4.25%), and the alternate base rate loan margin now ranges from 1.75% to 2.75% (previously 2.25% to 3.25%), in each case, based on borrowing base utilization.
●	Updates the commodity hedging covenant by increasing the borrowing base utilization threshold in certain provisions from 25% to 30%.
---	---
●	Amends certain lender schedules and makes technical, definitional and conforming changes.
---	---
●	Includes customary post-closing obligations requiring delivery of additional mortgages and title information covering specified percentages of the borrowing base properties.
---	---

The Amendment also includes customary representations and warranties, reaffirmations of the loan parties’ obligations under the loan documents, and releases in favor of the administrative agent and lenders.

Except as expressly amended by the Amendment, the terms of the Credit Agreement remain unchanged, including the revolving commitments, collateral package, financial covenants and maturity.

As of December 31, 2025 and February 27, 2026, there were no borrowings outstanding under the Credit Agreement, and the full $115.0 million borrowing base was available.

The foregoing description of the Amendment does not purport to be complete and is qualified in its entirety by reference to the full text of the Amendment, which is filed herewith as Exhibit 10.1 and incorporated herein by reference.

Section 6. Representations and Warranties. Before and after giving effect to this Amendment, the Borrower hereby confirms that (a) the representations and warranties of Borrower and each other Loan Party contained in the Credit Agreement and the other Loan Documents are true and correct in all material respects (except to the extent such representations and warranties are qualified by materiality, in which case they shall be true and correct in all respects) on and as of the Fifth Amendment Effective Date, except to the extent that such representations and warranties specifically refer to an earlier date, in which case they shall be true and correct in all material respects (except to the extent such representations and warranties are qualified by materiality, in which case they shall be true and correct in all respects) as of such earlier date, and (b) no Default or Event of Default shall have occurred and be continuing. The execution, delivery, and performance by each of Borrower and the Guarantors of this Amendment and compliance with the terms and provisions hereof have been duly authorized by all requisite action on the part of such Person and do not violate any contractual or other obligation by which such Person is bound.

Section 7. Acknowledgment and Ratification. As a material inducement to Administrative Agent and the Lenders to execute and deliver this Amendment, each Loan Party acknowledges and agrees that (a) the execution, delivery, and performance of this Amendment shall, except as expressly provided herein, in no way release, diminish, impair, reduce, or otherwise affect the obligations of such Person under the Loan Documents to which such Person is a party, (b) each Loan Document to which such Person is a party shall remain in full force and effect and shall each continue to be the legal, valid and binding obligations of such Person enforceable against such Person in accordance with its terms, and (c) it has no claims or offsets against, or defenses or counterclaims to, any of the Loan Documents. To induce the Administrative Agent and Lenders to agree to the terms of this Agreement, each Loan Party represents and warrants that as of the Fifth Amendment Effective Date, there are no claims or offsets or defenses or counterclaims to such Person’s obligations under the Loan Documents, and in accordance therewith each such Person: (i) waives any and all such claims, offsets, defenses or counterclaims, whether known or unknown, arising under the Loan Documents prior to the Fifth Amendment Effective Date; and (ii) releases and discharges the Administrative Agent and each Lender and its respective officers, directors, employees, agents, shareholders, affiliates and attorneys (the “Released Parties”) from any and all obligations, indebtedness, liabilities, claims, rights, causes of action or other demands whatsoever, whether known or unknown, suspected or unsuspected, in law or equity, which such Person ever had, now has or claims to have or may have against any Released Party arising prior to the Fifth Amendment Effective Date and from or in connection with the Loan Documents or the transactions contemplated thereby, except those resulting from the gross negligence or willful misconduct of the Released Party.

Section 8. Effect of Amendment. Without limiting the generality of the foregoing, the consent, waiver and modifications set forth herein shall be limited precisely as set forth above, and nothing in this Amendment shall be deemed (i) to constitute a waiver of compliance or consent to noncompliance by any of the Loan Parties to, or an amendment of, any other term, provision, condition or covenant of the Credit Agreement or other Loan Documents, other than as specifically set forth herein; or (ii) to prejudice any right or remedy that the Administrative Agent or the Lenders may now have or may have in the future under or in connection with the Credit Agreement or any other Loan Document. Upon the effectiveness of this Amendment, each reference in the Credit Agreement to “this Agreement”, “hereunder”, or words of like import shall mean and be a reference to the Credit Agreement, as affected hereby. This Amendment shall constitute a Loan Document for all purposes.

FIFTH AMENDMENT **** – Page 3

Section 9. Confirmation of Security and Guaranty. Each Loan Party hereby confirms and agrees that all of the Security Instruments that presently secure the Secured Obligations shall continue to secure, in the same manner and to the same extent provided therein, the payment and performance of the Secured Obligations as described in the Credit Agreement as modified by this Amendment. Each Loan Party further confirms and agrees that the Guaranty Agreement that presently guarantees the Secured Obligations shall continue to guarantee, in the same manner and to the same extent provided therein, the payment and performance of the Secured Obligations as described in the Credit Agreement as modified by this Amendment.

Section 10. Incorporation of Certain Provisions by Reference. The provisions of Section 12.09 of the Credit Agreement captioned “GOVERNING LAW; JURISDICTION; CONSENT TO SERVICE OF PROCESS” are incorporated herein by reference for all purposes.

Section 11. Execution in Counterparts. This Amendment may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed and delivered shall be deemed to be an original and all of which when taken together shall constitute but one and the same instrument. For purposes of this Amendment, a counterpart hereof (or signature page thereto) signed and transmitted by any Person party hereto to the Administrative Agent (or its counsel) by facsimile machine, telecopier or electronic mail is to be treated as an original. The signature of such Person thereon, for purposes hereof, is to be considered as an original signature, and the counterpart (or signature page thereto) so transmitted is to be considered to have the same binding effect as an original signature on an original document.

Section 12. Entirety. This Amendment and all of the other Loan Documents embody the entire agreement between the parties. THIS AMENDMENT AND ALL OF THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT AMONG THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.
