| Amendment Description | Supernova Partners Acquisition Company II, Ltd. (the “Company”) is filing this Amendment No. 1 to its Current Report on Form 8-K (the “First Amendment”) for the initial public offering (“IPO”) which closed on March 4, 2021, as originally filed with the U.S. Securities and Exchange Commission (the “SEC”) on March 10, 2021 (the “Original Form 8-K”) to amend and restate the Company’s audited balance sheet and accompanying footnotes as of March 4, 2021 (the “IPO Balance Sheet”) as further described below. This First Amendment on Form 8-K/A is presented as of the filing date of the Original Form 8-K and does not reflect events occurring after that date or modify or update disclosures in any way other than as required to reflect the restatement as described below. Accordingly, this First Amendment on Form 8-K/A should be read in conjunction with our filings with the SEC subsequent to the date on which we filed the Original Form 8-K. The Company is filing this First Amendment on Form 8-K/A to reflect a restatement of the Company’s IPO Balance Sheet, to account for the Company’s warrants as derivative liabilities instead of components of equity and to reclassify a portion of its public shares from permanent equity to temporary equity. |
