Amendment Description	On July 23, 2020, management of Panhandle Oil and Gas Inc. (the “Company”) concluded, and the Audit Committee of the Board of Directors concurred, that the Company's previously-issued unaudited financial statements as of and for the three- and six- month periods ended March 31, 2020, which were included in the Company's Quarterly Report on Form 10-Q for the quarter ended March 31, 2020, originally filed with the Securities and Exchange Commission (the "SEC") on May 7, 2020 (the “Original Filing”), should no longer be relied upon and should be restated to correct the errors discussed below. The Company is filing this Amendment No. 1 to the Quarterly Report on Form 10-Q/A (the “Amendment”), which sets forth the information in the Original Filing in its entirety, as adjusted for the effects of the restatement described below. During the process of collecting receivables recorded in the oil, NGL and natural gas revenue accrual as of March 31, 2020, the Company identified a misstatement of approximately $705,000 attributable to errors in identifying ownership interests in wells, resulting in an overstatement of the Company’s net revenue interest in three wells. As a result of the overstatement in revenue, refundable income taxes and deferred income taxes were misstated by approximately $176,000 and $47,000, respectively. Oil, NGL and natural gas sales, transportation, gathering and marketing, production taxes and benefit for income taxes were misstated by approximately $765,000, $30,000, $31,000 and $223,000, respectively, for the three and six months ended March 31, 2020. The misstatements were related to the non-recurring revenue accruals discussed in the quarter ended March 31, 2020 and do not affect cash flow from operations, debt and cash balances for the three- and six-month periods ended March 31, 2020. This Amendment is being filed to (i) restate the unaudited financial statements to correct the misstatements described above (and to reflect corresponding changes to the Risk Factors in Part II, Item 1A, and to Management's Discussion and Analysis of Financial Condition and Results of Operations in Part I, Item 2), and (ii) amend Part 1, Item 4 (Controls and Procedures) to address the material weakness in internal control that caused the misstatements. To reflect the restatement of items described above, this Amendment revises the following sections of the Original Filing: •Part I - Item 1. Condensed Financial Statements; •Part I - Item 2. Management's Discussion and Analysis of Financial Conditions and Results of Operations; •Part I - Item 4. Controls and Procedures; •Part II - Item 1A. Risk Factors; and •Part II - Item 6. Exhibits The misstatements giving rise to this Amendment resulted from a material weakness in internal control over financial reporting. As such, Item 4 of Part I has been amended to include our assessment of the effectiveness of our disclosure controls and procedures pursuant to Rule 13a-15(b) under the Securities Exchange Act of 1934, as amended. This Amendment includes new certifications from the Company’s Chief Executive Officer and President and Chief Financial Officer dated as of the date of the filing of this Amendment, as required by Sections 302 and 906 of the Sarbanes-Oxley Act of 2002. The certifications are filed with this Amendment as Exhibits 31.1, 31.2, 32.1 and 32.2. Except as described above, no other changes have been made to the Original Filing. This Amendment does not reflect events occurring after, nor does it modify or update any disclosures that may have been affected by events occurring subsequent to, the date of the filing of the Original Filing.
