UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS
The unaudited pro forma condensed combined 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 combined financial information combines the historical consolidated financial position and results of operations of Riley Exploration Permian, Inc. (“Riley Permian”) and the historical consolidated financial position and results of operations of Silverback Exploration II, LLC (“Silverback”) after giving effect to the Silverback Acquisition 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 Combined Financial Information” below. The unaudited pro forma condensed combined financial information has been prepared to give effect to the following (collectively, the “Transactions”):
Application of the acquisition method of accounting under the provisions of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 805, Business Combinations (“ASC 805”) where the assets acquired and liabilities assumed of Silverback will be recorded by Riley Permian at their respective fair values as of the closing date;
Preliminary adjustments to conform the financial presentation of Silverback to those of Riley Permian;
Other transaction accounting adjustments, including transaction costs of the Silverback Acquisition; and
Other financing transaction accounting adjustments, including the effect of the drawdown on the credit facility.
The following pro forma financial statements and related notes are based on and should be read in conjunction with:
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;
The historical audited consolidated financial statements of Silverback and the related notes included herein as of and for the year ended December 31, 2024;
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 three months ended March 31, 2025; and
The historical unaudited condensed consolidated financial statements of Silverback and the related notes included herein as of and for the three months ended March 31, 2025.
The unaudited pro forma condensed combined balance sheet as of March 31, 2025, gives pro forma effect to the Transactions as if they had been consummated on March 31, 2025. The unaudited pro forma condensed combined statements of operations for the three months ended March 31, 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 combined financial information has been prepared using the acquisition method of accounting pursuant to the provisions of ASC 805, whereby Riley Permian is considered the accounting acquirer. The consideration transferred will be allocated to the identifiable assets acquired and liabilities assumed based upon their estimated fair values as of the acquisition date, and any excess value of the consideration transferred over the acquired net assets will be recognized as goodwill, if applicable. The assets and liabilities of Silverback have been measured based on various preliminary estimates using assumptions that Riley Permian believes are reasonable based on information that is currently available. As a result, the unaudited pro forma condensed combined financial information has been presented for illustrative purposes only and is not necessarily indicative of the financial position and results of operations that would have been achieved had the Transactions occurred on the dates indicated.

The unaudited pro forma condensed combined 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/A, 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. As of the date of this filing, the valuation of the identifiable assets acquired and liabilities assumed remains ongoing and adjustments may be made. Riley Permian expects to complete the final purchase price allocation during the 12-month period subsequent to the close date.

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

Note 1. Description of the Transactions and Basis of Presentation
Acquisition of Silverback
On July 1, 2025 (“Closing Date”), Riley Permian completed its previously announced acquisition of 100% of the ownership interests of Silverback (the “Silverback Acquisition”). The Silverback Acquisition was completed pursuant to the securities purchase agreement (the “Purchase Agreement”) dated May 3, 2025, which provided for an aggregate purchase price of approximately $142 million, subject to customary purchase price adjustments, plus quarterly earnout payments of up to approximately $1.9 million per fiscal quarter during calendar years 2026 and 2027, contingent upon the NYMEX WTI quarterly average exceeding specified thresholds ranging $70 to $75 per barrel or higher. At closing on July 1, 2025, the fair value of the consideration transferred was adjusted to approximately $129 million, which reflected certain purchase price adjustments and inclusion of the fair value of the contingent consideration. We funded the cash consideration with borrowings from our revolving credit facility.
Basis of Presentation
The unaudited pro forma condensed combined financial information has been prepared in accordance with Article 11. The unaudited pro forma condensed combined balance sheet as of March 31, 2025, combines the historical unaudited condensed consolidated balance sheets of Riley Permian and Silverback, giving effect to the Transactions as if they had been consummated on March 31, 2025. The unaudited pro forma condensed combined statements of operations for the three months ended March 31, 2025, and for the year ended December 31, 2024, combines the historical condensed consolidated statements of operations of Riley Permian and Silverback, giving 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 Silverback Acquisition under the acquisition method of accounting whereby Riley Permian is considered the accounting acquirer. The pro forma financial statements are presented for informational purposes only and do not necessarily indicate the financial results of the combined company had the companies been combined 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 combined company. The results of operations of the combined company will be reported prospectively after closing following completion of the Silverback Acquisition. Under the acquisition method of accounting, the assets and liabilities of Silverback, as of closing, will be recorded by Riley Permian at their estimated fair values and any excess of the consideration transferred over the fair value of Silverback’s net assets will be allocated to goodwill, if applicable. The pro forma allocation of the consideration transferred reflected in the pro forma financial statements is subject to adjustment and may vary materially from the actual allocation that will be recorded as of the closing date.
The unaudited pro forma condensed combined financial information is presented for illustrative purposes only and does not reflect the costs of any integration activities or cost savings or synergies that may be achieved as a result of the Silverback Acquisition.
Note 2. Significant Accounting Policies and Reclassification Adjustments
During the preparation of the pro forma financial statements, Riley Permian performed a preliminary analysis of Silverback’s historical financial information to identify differences in accounting policies and financial statement presentation as compared to those of Riley Permian. Accordingly, certain reclassification adjustments have been made to conform Silverback’s historical financial statements to the presentation used by Riley Permian in the preparation of the pro forma financial statements.
The following reclassification adjustments were made to conform the presentation of Silverback’s historical condensed consolidated balance sheet as of March 31, 2025, to Riley Permian’s presentation:
