EXPLANATORY NOTE

Reason for this Amendment

This Amendment No. 2 on Form 10-K/A ( the "Amendment No. 2") to the Annual Report on Form 10-K for the fiscal year ended December 31, 2019 (the "2019 Form 10-K") of Hallador Energy Company ("Hallador" the "Company," "we," or "us") originally filed on March 9, 2020 (the "Original Filing"), as amended by Amendment No. 1 to the Original Filing (the "Amendment No. 1"), is filed to include disclosures required by the Securities and Exchange Commission Order dated March 4, 2020 (Release No. 34-88318), as modified on March 25, 2020 (Release No. 34-88465) (the "Order") that provided 45-day conditional relief to public companies unable to timely comply with their filing obligations as a result of COVID-19. At the time the Company filed its Original Filing, it intended to file a definitive proxy statement for its 2020 Annual Meeting of Shareholders within 120 days of the end of its fiscal year. Amendment No. 1 was filed to present the information required by Part III of the 2019 Form 10-K, as we did not file our definitive proxy statement within 120 days of our fiscal year ended December 31, 2019. This Amendment No. 2 is being filed to include the disclosure below in accordance with the Order, which was inadvertently omitted from Amendment No. 1.

Reliance on SEC Relief from Filing Requirements

The Company filed, on April 29, 2020, a Current Report on Form 8-K indicating the preparation and filing of the information required for Part III of the 2019 Form 10-K was delayed due to the COVID-19 pandemic and related events which resulted in management devoting significant time and attention to assessing the potential impact of COVID-19 and those events on the Company's operations and financial position and developing operational and financial plans to address those matters. Also, out of an abundance of caution, certain employees at our corporate headquarters, including financial reporting and accounting staff, began working remotely when the state of Indiana's "stay at home" order went into effect March 23, 2020.

In accordance with Rules 12b-15 and 13a-14 under the Exchange Act, the Company has also amended Item 15 of Part IV to include currently dated certifications pursuant to Section 302 of the Sarbanes-Oxley Act of 2002. Because no financial statements have been included in this Amendment No. 2 and this Amendment No. 2 does not contain or amend any disclosures with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4, and 5 of the certifications have been omitted. Similarly, because no financial statements have been included in this Amendment No. 2, certifications pursuant to Section 906 of the Sarbanes-Oxley Act of 2002 have been omitted.

Except as described above, no other changes have been made to the Original Filing and Amendment No. 1. The Original Filing and Amendment No. 1 continue to disclose information as of the date of filing of the Original Filing and Amendment No. 1, respectively, and we have not updated the disclosures contained therein to reflect any subsequent developments or events. This Amendment No. 2 should be read in conjunction with our Original Filing and Amendment No. 1 and our other filings with the Securities and Exchange Commission.
