ASP Isotopes Inc. ("ASP Isotopes," the "Company," "we," "us," or "our") is filing this Amendment No. 1 on Form 10-K/A (this "Amendment") to amend our Annual Report on Form 10-K for the fiscal year ended December 31, 2025, originally filed with the Securities and Exchange Commission (the "SEC") on April 10, 2026 (the "Original Filing"), to include the information required by Items 10 through 14 of Part III of Form 10-K. We previously omitted this information from our Original Filing in reliance on General Instruction G(3) to Form 10-K, which permits the information in the above-referenced items to be incorporated in the Original Filing by reference to our definitive proxy statement if such statement is filed no later than 120 days after our fiscal year-end. We are filing this Amendment to provide the information required in Part III of Form 10-K because we will not file a definitive proxy statement containing that information within 120 days after the end of the fiscal year covered by our Original Filing.
This Amendment amends and restates in their entirety Items 10, 11, 12, 13 and 14 of Part III of our Original Filing. The cover page of our Original Filing is also amended to delete the reference to the incorporation by reference of portions of our definitive proxy statement into Part III of the Original Filing. In addition, as required by Rule 12b-15 under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), Item 15 of Part IV of the Original Filing is hereby amended solely to include, as Exhibits 31.1 and 31.2, new certifications by the Company's Principal Executive Officer and Principal Financial Officer pursuant to Rule 13a-14(a) under the Exchange Act. Because no financial statements have been included in this Amendment, and this Amendment does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4 and 5 of the certifications have been omitted. In addition, because no financial statements are included in this Amendment, new certifications of the Company's Principal Executive Officer and Principal Financial Officer pursuant to Section 906 of the Sarbanes-Oxley Act of 2002 are not required to be included with Amendment.
Except as described above, this Amendment does not amend any other information set forth in the Original Filing, and the Company has not updated disclosures included therein to reflect any subsequent events. Accordingly, this Amendment should be read in conjunction with our Original Filing and with our filings with the SEC subsequent to the Original Filing.
