Amendment Description This Amendment No. 1 on Form 10-K/A (“Amendment No. 1”) of Nova Minerals Corp is being filed to amend our Annual Report on Form 10-K for the fiscal year ended June 30, 2026, originally filed on September 30, 2026 (the “Original Filing”) to provide information required in Part III of Form 10-K. This information was previously omitted from the Original Filing in reliance on General Instruction G(3) of Form 10-K, which permits such information to be incorporated by reference in the Form 10-K from our definitive proxy statement if such proxy statement is filed no later than 120 days after the end of our fiscal year. In accordance with Rule 12b-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), Items 10 through 14 of Part III of the Original Filing have been amended and restated in their entirety, and Item 15 of Part IV of the Original Filing has also been amended and restated in its entirety to include new certifications by our principal executive officer and principal financial officer. This Amendment No. 1 does not amend or otherwise update any other information in the Original Filing. Accordingly, this Amendment No. 1 should be read in conjunction with the Original Filing and with our other filings with the Securities and Exchange Commission (“SEC”) subsequent to the Original Filing.
