On June 30, 2025, Evolution Petroleum Corporation (the “Company” or “Evolution”), entered into an amended and restated senior secured reserve-based credit agreement (the “Senior Secured Credit Facility”) with MidFirst Bank, as administrative agent for the lenders party thereto, in an amount up to $200.0 million with an initial borrowing base of $65.0 million maturing on June 30, 2028. Current borrowings outstanding are $37.5 million.

Proceeds of any loans may be used for working capital in the ordinary course of business, for the acquisition of Oil and Gas Properties, and for the drilling and development of the Oil and Gas Properties of the Company and its subsidiaries.

The Senior Secured Credit Facility contains certain events of default, including non-payment; breaches of representation and warranties; non-compliance with covenants; cross-defaults to material indebtedness; voluntary or involuntary bankruptcy; judgments and change in control. The Senior Secured Credit Facility also contains financial covenants including a requirement that the Company maintain, as of the last day of each fiscal quarter, (i) a maximum total leverage ratio of not more than 3.00 to 1.00, (ii) a current ratio of not less than 1.00 to 1.00, and (iii) a consolidated tangible net worth of not less than $40.0 million, each as defined in the Senior Secured Credit Facility. In addition, the Senior Secured Credit Facility contains hedging requirements that apply when utilization is greater than 25% of (x) the Margined Collateral Value, as defined under the Senior Secured Credit Facility, at any time when the leverage ratio is less than 2.25 to 1.00, or (y) the borrowing base, at any time when the leverage ratio is greater than or equal to 2.25 to 1.00.

The Senior Secured Credit Facility carries a commitment fee of 0.25% per annum on the undrawn portion of the borrowing base. Any borrowings under the Senior Secured Credit Facility will bear interest, at the Company’s option, at either (i) the Secured Overnight Financing Rate (“SOFR”), subject to a minimum SOFR of 3.25%, plus a credit spread adjustment of 0.05%, or (ii) the Prime Rate, as defined under the Senior Secured Credit Facility, plus 1.00%, plus, in either case of (i) or (ii), and applicable margin of 2.75%.

The Company and certain subsidiaries granted a mortgage to MidFirst Bank on substantially all of their oil and gas properties, including all of their present and future mineral interests in such properties. The Company’s subsidiaries guaranteed the Company’s obligations under the facility. The Senior Secured Credit Facility is subject to certain customary representations and warranties, affirmative covenants, negative covenants and post-closing covenants consistent with agreements of this type.

The foregoing description of the Senior Secured Credit Facility does not purport to be complete and is qualified in its entirety by reference to the Senior Secured Credit Facility filed as Exhibit 10.2 to this Current Report on Form 8-K and incorporated into this Item 1.01 by reference.

On July 1, 2025, Evolution announced the initial results of its joint venture audit of its Barnett Shale properties. In fiscal year 2024, Evolution exercised its right to perform a joint interest audit of expenses charged from the largest operator of its Barnett Shale properties, for the calendar years 2022-2023. The initial findings produced several areas where it appeared Evolution had been over-charged and, so far, Evolution and the operator have discovered approximately $1.8 million owed to Evolution relating to the September 2021 through December 2023 time period. This amount will be recognized as a reduction to lease operating expenses and accounts payable in the Company’s fiscal fourth quarter and full-year 2025 results. Evolution plans to continue with its rights under the joint operating agreement to audit future periods.
