Amendment Description	Unless the context otherwise requires, the term “the Company” and “Emerson,” refers to Emerson Radio Corp. and its subsidiaries.   This Amendment No. 1 on Form 10-K/A (the “Form 10-K/A”) to the Annual Report on Form 10-K (the “Annual Report”) of the Company for the fiscal year ended March 31, 2023 (“Fiscal 2023”), filed with the Securities and Exchange Commission (the “SEC”) on June 26, 2023, is filed solely for the purpose of including information that was to be incorporated by reference from the Company’s definitive proxy statement pursuant to Regulation 14A of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The Company will not file its proxy statement for its annual meeting of stockholders within 120 days of its fiscal year ended March 31, 2023, and is therefore amending and restating in their entirety Items 10, 11, 12, 13 and 14 of Part III of the Annual Report. In addition, pursuant to Rule 13a-14(a) under the Exchange Act, the Company is amending Item 15 of Part IV of the Annual Report to update the exhibit list and to include certain currently dated certifications. Except as described above, no other amendments are being made to the Annual Report. This Form 10-K/A does not reflect events occurring after the filing of the Annual Report on June 26, 2023 or modify or update the disclosure contained in the Annual Report in any way other than as required to reflect the amendments discussed above and reflected below.
