The audited balance sheet is being refiled to reflect the classification of the Company’s warrants as a liability, in accordance with the SEC’s April 12, 2021 public statement informing market participants that warrants issued by special purpose acquisition companies may need to be classified as liabilities.

In addition, the information contained in this Amendment does not reflect events occurring after the filing of the Original 8-K and does not modify or update the disclosures therein, except as specifically identified above. Among other things, forward-looking statements made in the Original 8-K have not been revised to reflect events, results or developments that occurred or facts that became known to us after the date of the Original 8-K, other than as described herein, and such forward-looking statements should be read in conjunction with the Company’s filings with the SEC.
