| Amendment Description | Nikola Corporation (the “Company,” “we,” “our,” or “us”) is filing this Amendment No. 1 (the “Amended Report”) to the Company’s Annual Report on Form 10-K for the year ended December 31, 2021, filed with the Securities and Exchange Commission (the “SEC”) on February 24, 2022 (the “Original Report”), in order to (i) add certain information required by Items 10, 11, 12, 13 and 14 of Part III of Form 10-K and (ii) amend and restate the Forward-Looking Statements included in the Original Report in its entirety. We hereby amend Items 10, 11, 12, 13 and 14 and the Forward-Looking Statements to the Original Report by deleting the text of such Items 10, 11, 12, 13 and 14 and the Forward-Looking Statements in their entirety and replacing them with the information provided below under the respective headings. The Amended Report does not affect any other items in the Original Report. As a result of this amendment, we are also filing as exhibits to this Amended Report the certifications pursuant to Section 302 of the Sarbanes-Oxley Act of 2002. Because no financial statements are contained in this Amended Report, we are not including certifications pursuant to Section 906 of the Sarbanes-Oxley Act of 2002. Except as otherwise expressly stated for the Items amended in this Amended Report, this Amended Report continues to speak as of the date of the Original Report and we have not updated the disclosure contained herein to reflect events that have occurred since the filing of the Original Report. Accordingly, this Amended Report should be read in conjunction with the Original Report and our other filings made with the SEC subsequent to the filing of the Original Report. | ||
