Supernova Partners Acquisition Company, Inc. Receives Expected Notice From The New York Stock Exchange Regarding Delayed Quarterly Report

June 2, 2021

WASHINGTON, D.C, June 2, 2021 /PRNewswire/ — Supernova Partners Acquisition Company, Inc. (NYSE: SPNV) (the “Company,” “Supernova,” “us” or “our”) announced today that, on May 25, 2021, it received a notice (“Notice”) from the New York Stock Exchange (the “NYSE”) indicating that it was not in compliance with NYSE continued listing requirements under the timely filing criteria established in Section 802.01E of the NYSE Listed Company Manual as a result of its failure to timely file the Form 10-Q for the fiscal quarter ended March 31, 2021 (the “Form 10-Q”). The Rule requires listed companies to timely file all required periodic financial reports with the Securities and Exchange Commission (“SEC”). The Notice has no immediate effect on the listing or trading of the Company’s securities on the NYSE.

On April 12, 2021, the Acting Director of the Division of Corporation Finance and Acting Chief Accountant of the SEC together issued a statement regarding the accounting and reporting considerations for warrants issued by special purpose acquisition companies entitled “Staff Statement on Accounting and Reporting Considerations for Warrants Issued by Special Purpose Acquisition Companies” (the “SEC Statement”). As result of the SEC Statement, the Company’s management reevaluated the accounting treatment of (i) the redeemable warrants that were included in the units issued by the Company in its initial public offering, (ii) the redeemable warrants that were issued in a private placement (collectively, the “Warrants”), and (iii) the forward purchase agreements. As reported by the Company in its Form 12b-25 filed with the SEC on May 17, 2021, given the scope of the process for evaluating the impact of the SEC Statement on the Company’s financial statements, the Company was unable to file the Form 10-Q within the prescribed time period without unreasonable effort or expense. The Company filed the Form 10-Q with the SEC on May 28, 2021.
