## Exhibit 99.1

***Exhibit 99.1***

**RILEY EXPLORATION PERMIAN, INC.**

**UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

The unaudited pro forma condensed consolidated financial information is prepared in accordance with Article 11 of Regulation S-X of the Securities Exchange Act of 1934 ("Article 11") and should be read in conjunction with the accompanying notes. The following unaudited pro forma condensed consolidated financial statements are presented to show the effect on the historical condensed consolidated financial statements of Riley Exploration Permian, Inc ("Riley Permian" or "the Company") from the sale of the Company's midstream property and equipment ("Midstream Sale") as further described in Note 1. Description of the Transactions and Basis of Presentation and the pro forma effects of certain assumptions and adjustments described in "Notes to the Unaudited Pro Forma Condensed Consolidated Financial Information" below. The unaudited pro forma condensed consolidated financial information has been prepared to give effect to the following (collectively, the "Transactions"):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Application of the derecognition guidance under the provisions of the Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 610-20, *Gains and Losses from the Derecognition of Nonfinancial Assets* ("ASC 610-20"), whereby Riley Permian will derecognize the assets sold and any associated liabilities transferred, and recognize a gain measured as the difference between the consideration received and the carrying amounts of the assets and liabilities derecognized, net of any selling costs; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Other transaction accounting adjustments, including the effect of the paydown on the Company's revolving credit facility ("Credit Facility").

The following pro forma financial statements and related notes are based on and should be read in conjunction with:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ The historical audited consolidated financial statements of Riley Permian and the related notes included in Riley Permian's Annual Report on Form 10-K as of and for the year ended December 31, 2024; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ The historical unaudited condensed consolidated financial statements of Riley Permian and the related notes included in Riley Permian's Quarterly Report on Form 10-Q as of and for the nine months ended September 30, 2025.

The unaudited pro forma condensed consolidated balance sheet as of September 30, 2025, gives pro forma effect to the Transactions as if they had been consummated on September 30, 2025. The unaudited pro forma condensed consolidated statements of operations for the nine months ended September 30, 2025, and for the year ended December 31, 2024, give pro forma effect to the Transactions as if they had been consummated on January 1, 2024.

The unaudited pro forma condensed consolidated financial information appearing below is based on available preliminary information and certain assumptions that are believed to be reasonable as of the date of this Form 8-K, and also does not consider any potential effects of changes in market conditions on revenues or expense efficiencies, among other factors. Future results may vary significantly from the results reflected because of various factors.

**NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

**Note 1. Description of the Transactions and Basis of Presentation** 

***Sale of Midstream***

On December 3, 2025, Riley Exploration - Permian, LLC. ("REP LLC"), a wholly-owned subsidiary of Riley Exploration Permian, Inc. ("REPX," together with REP LLC, hereinafter referred to as the "Company"), entered into a purchase and sale agreement (the "Purchase Agreement") with Targa Northern Delaware LLC ("Buyer"), pursuant to which the Company sold to Buyer all of the membership interests in Dovetail Midstream, LLC, a wholly owned subsidiary of the Company that holds certain midstream infrastructure projects in Eddy County, New Mexico, for an aggregate cash purchase price of approximately $111 million, subject to customary purchase price adjustments (the "Midstream Sale"). The Midstream Sale also provided for the sale by the Company to Buyer of certain compressor station assets for an aggregate cash purchase price of approximately $10 million plus reimbursement of $1.4 million of capital improvements at a subsequent closing (the "Second Closing"), subject to the satisfaction of certain closing conditions. The initial closing of the Midstream Sale took place on December 3, 2025, and the Second Closing occurred on December 24, 2025. Closing proceeds from the transaction will be used to reduce borrowings on the Company's Credit Facility and pay selling costs associated with the transaction. The Company also has the right to earn up to an additional $60 million earn out in cash contingent on achieving certain volume-based performance thresholds over a five-year period.

***Basis of Presentation***

The unaudited pro forma condensed consolidated financial information has been prepared in accordance with Article 11. The unaudited pro forma condensed consolidated balance sheet as of September 30, 2025, gives pro forma effect to the Transactions as if they had been consummated on September 30, 2025. The unaudited pro forma condensed consolidated statements of operations for the nine months ended September 30, 2025, and for the year ended December 31, 2024, gives pro forma effect to the Transactions as if they had been consummated on January 1, 2024.

The pro forma financial statements and explanatory notes have been prepared to illustrate the effects of the Midstream Sale, which does not meet the definition of a business under ASC 805 and is therefore accounted for as the derecognition of nonfinancial assets under ASC 610-20, pursuant to which Riley Permian is treated as the seller for accounting purposes. The pro forma financial statements are presented for informational purposes only and do not necessarily indicate the financial results of the disaggregated company had the sale occurred at the beginning of the periods presented, nor do they necessarily indicate the results of operations in future periods or the future financial position of the company. The pro forma presentation of the consideration received is preliminary and subject to adjustment. The final allocation of consideration among the derecognized assets and liabilities may differ materially from the amounts shown as of the applicable closing dates.

The unaudited pro forma condensed consolidated financial information is presented for illustrative purposes only and does not reflect any costs associated with the separation or transition activities that may occur as a result of the Midstream Sale or any changes the Company may make to its operations after the disposition.

**Note 2. Adjustments to the Unaudited Pro Forma Condensed Consolidated Balance Sheet**

The following adjustments correspond to those included in the unaudited condensed consolidated pro forma balance sheet as of September 30, 2025.

***Midstream Transaction Adjustments***

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)Represents the cash proceeds from the Midstream Sale, net of selling costs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)Represents the carrying amounts of assets and liabilities derecognized from the Midstream Sale. An adjustment of $17.4 million to midstream property and equipment, with a corresponding increase to accrued liabilities, was recorded to reflect the additional costs incurred by the Company after September 30, 2025. As a result, the estimated gain described in note 2(c) was reduced by this amount.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)Represents the estimated gain on the Midstream Sale as if the sale had occurred on September 30, 2025. This gain may not be representative of what will actually be recorded during the year ended December 31, 2025.

***Midstream Transaction Adjustments***

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)Represents the income and expenses eliminated in connection with the Midstream Sale.

A blended statutory rate of 25.7% has been assumed for purposes of the pro forma adjustments. The blended statutory rate may not be indicative of the effective tax rate of the company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)Represents the estimated gain on the Midstream Sale as if the sale had occurred on January 1, 2024. This gain may not be representative of what will actually be recorded during the year ended December 31, 2025.
