| Amendment Description | Minerva Neurosciences, Inc. (the “Company,” “Minerva,” “we,” “us” or “our”) is filing this Amendment No. 2 on Form 10-K/A (this “Amendment”) to amend our Annual Report on Form 10-K for the year ended December 31, 2023, originally filed with the Securities and Exchange Commission (the “SEC”) on February 22, 2024 (the “Original 10-K”), to (i) include the information required by Items 10 through 14 of Part III of Form 10-K and (ii) amend Item 15 of Part IV of the Original 10-K to update the exhibit list. The information required by Items 10 through 14 of Part III of Form 10-K was previously omitted from the Original 10-K 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 Form 10-K by reference from 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 include Part III information in our Form 10-K because a definitive proxy statement containing such information may not be filed by Minerva within 120 days after the end of the fiscal year covered by the Form 10-K.In accordance with Rule 12b-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), Part III, Items 10 through 14 of the Original 10-K are hereby amended and restated in their entirety. Additionally, in accordance with Rules 12b-15 and 13a-14 under the Exchange Act, we have amended Part IV, Item 15 to include currently dated certifications pursuant to Section 302 of the Sarbanes-Oxley Act of 2002. Since no new 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. Similarly, since no financial statements have been included in this Amendment, certifications pursuant to Section 906 of the Sarbanes-Oxley Act of 2002 have been omitted. Except for the changes to Part III and Item 15 of Part IV, including the filing of related certifications added to the exhibit list in Part IV, this Amendment makes no changes to the Original 10-K. This Amendment does not reflect events occurring after the filing of the Original 10-K or modify disclosures affected by subsequent events. Terms used but not otherwise defined in this Amendment have such meaning as ascribed to them in the Original 10-K. | | |
