Amendment Description	This Amendment No. 1 to the Annual Report on Form 10-K/A (the “Amendment”) amends the Annual Report on Form 10-K of Ault Alliance, Inc., which was then known as BitNile Holdings, Inc. (the “Company”) for the year ended December 31, 2021 (the “Original Filing”), that was originally filed with the U.S. Securities and Exchange Commission on April 15, 2022. This Report only amends and restates Item 7, Item 8 and Item 9A of Part II of the Original Report to reflect the restatement. The foregoing items have not been updated to reflect other events occurring after the date of the Original Report (other than the Name Change, as defined below), or to modify or update those disclosures affected by subsequent events. Subsequent to the date of filing of the Original Filing, the Company merged its wholly owned subsidiary, Ault Alliance, Inc., with and into the Company, and in connection therewith, changed its name from BitNile Holdings, Inc. to Ault Alliance, Inc. (the “Name Change”).  As such, other than on the cover page of this Amendment, the signature page to this Amendment, and the revised disclosures contained in Item 7 and Item 8, which reflects the Name Change, all other references in this Amendment to Ault Alliance, Inc. refers to the former wholly owned subsidiary of the same name, and not to the Company.  In addition, the exhibit list in Item 15 of Part IV has been updated only to include currently dated certifications from the Company’s Chief Executive Officer and Chief Financial Officer, as required by Sections 302 and 906 of the Sarbanes-Oxley Act of 2002, are filed with this Amendment as Exhibit 31.1, 31.2 and 32.1.   The Amendment is being filed to correct an error in classification with respect to changes in fair value of financial instruments issued by a related party. The changes in fair value were erroneously recorded in other comprehensive income (loss) and have been reclassified to correct for the error within the statement of operations.
