The Registration Statement registered the resale of 35,398,389 shares of Class A common stock of the Company by the registered stockholders identified in the prospectus included in the Registration Statement. As disclosed in the Registration Statement, the Company intended to maintain the effectiveness of the Registration Statement for 90 days, during which period the Company would be subject to the reporting requirements of Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as amended, thereby satisfying the “current public information” requirements of Rule 144 under the Securities Act of 1933, as amended (“Rule 144”), as of the end of such 90-day period.

In accordance with an undertaking made by the Company in the Registration Statement to remove by means of a post-effective amendment any of the securities registered which remain unsold at the termination of the offering, this Post-Effective Amendment No. 1 to the Registration Statement is being filed to be effective as of 9:00 a.m., Washington, D.C. time, on December 21, 2021 to terminate the effectiveness of the Registration Statement and to remove from registration all securities registered but not sold under the Registration Statement.
