| Amendment Description | This Amendment No. 1 on Form 10-K/A, (this "Amendment"), amends our Annual Report on Form 10-K for the year ended December 31, 2023, originally filed with the Securities and Exchange Commission, or the SEC, on February 29, 2024, (the "Original Filing"). We are filing this Amendment pursuant to General Instruction G(3) of Form 10-K to include the information required by Part III of Form 10-K that we did not include in the Original Filing, as we do not intend to file a definitive proxy statement for an annual meeting of stockholders within 120 days of the end of our fiscal year ended December 31, 2023. In addition, in connection with the filing of this Amendment and pursuant to Rule 12b-15 under the Securities Exchange Act of 1934, as amended, or the Exchange Act, we are including with this Amendment new certifications of our principal executive officer and principal financial officer pursuant to Section 302 of the Sarbanes-Oxley Act of 2002. Item 15 of Part IV has also been amended to reflect the filing of these new certifications and certain other exhibits. Except as described above, no other changes have been made to the Original Filing. The Original Filing continues to speak as of the date of the Original Filing, and we have not updated the disclosures contained therein to reflect any events which occurred at a date subsequent to the filing of the Original Filing. | | |
