Amendment Description	The Reserve Petroleum Company (the “Company,” “we,” “our” or “us”) filed its Annual Report on Form 10-K for the year ended December 31, 2022 (the “Original 10-K Filing”) with the Securities and Exchange Commission on March 31, 2023. Pursuant to General Instruction G(3) to Form 10-K, the Company incorporated by reference the information required by Part III of Form 10-K from our definitive proxy statement for the 2023 Annual Meeting of Shareholders (the “2023 Proxy Statement”) that we expected to file with the Commission no later than 120 days after the end of the fiscal year covered by the Original 10-K Filing. Because the definitive 2023 Proxy Statement was not filed with the Commission before such date, the Company is filing this Amendment No. 1 to the Original 10-K Filing (this “Form 10-K/A”) to provide the additional information required by Part III of Form 10-K.   Except for the addition of Part III information and the filing of the new certifications by our principal executive officer and principal financial officer, this Form 10-K/A does not amend or otherwise update any other information in the Original 10-K Filing, and the Original 10-K Filing, as amended by this Form 10-K/A, continues to speak as of the date of the Original 10-K Filing. Accordingly, this Form 10-K/A should be read in conjunction with the Original 10-K Filing and with our filings with the SEC subsequent to the Original 10-K Filing.
