All capitalized terms contained herein but not otherwise defined shall have the meanings ascribed to them in the Schedule 13D. Information given in response to each Item shall be deemed incorporated by reference in all other Items of the Schedule 13D, as amended.

Item 5. Interest in Securities of the Issuer

Item 5 of the Schedule 13D is hereby amended and restated in its entirety as follows:

(a) and (b)          All percentages set forth in this Item 5 were calculated in accordance with Rule 13(d)-3(d)(1)(i) promulgated under the Exchange Act, and based on an aggregate total of 208,578,693 shares of the Issuer’s Class A Common Stock outstanding as of August 4, 2023 as reported by the Issuer in its Quarterly Report for the period ended June 30, 2023, filed on Form 10-Q with the SEC on August 14, 2023.

As of the date of this Amendment, the Reporting Persons may be deemed to beneficially own, for purposes of Rule 13d-3(d)(1)(i) of the Exchange Act, an aggregate total of 11,518,279 shares of the Class A Common Stock of the Issuer, which represents 5.5% of the Issuer’s outstanding Class A Common Stock, and which includes (i) an aggregate 4,159,347 shares of Class A Common Stock and (ii) an aggregate 7,358,932 shares of Class B Common Stock which are convertible at any time into an equal number of shares of Class A Common Stock at the election of the holder or automatically upon certain transfers. The Reporting Persons did not, and do not, have the right to acquire any additional shares of Class A Common Stock within sixty days of April 14, 2022 (the “Forfeiture Date”) or the date of this Amendment.

As of the date of this Amendment, assuming the conversion of all of the Reporting Persons’ shares of Class B Common Stock into shares of the Issuer’s Class A Common Stock, Hight Drive may be deemed to have: (i) sole power to vote and dispose, or direct the vote and disposition of, 0 shares, or 0.0%, of the Issuer’s Class A Common Stock and (ii) shared power to vote and dispose, or direct the vote and disposition of, 7,358,932 shares, or 3.5%, of the Issuer’s Class A Common Stock.

As of the date of this Amendment, assuming the conversion of all of the Reporting Persons’ shares of Class B Common Stock into shares of the Issuer’s Class A Common Stock, Mr. Adcock may be deemed to have: (i) sole power to vote and dispose, or direct the vote and disposition of, 4,159,347 shares, or 2.0%, of the Issuer’s Class A Common Stock and (ii) shared power to vote and dispose, or direct the vote and disposition of, 11,518,279 shares, or 5.5%, of the Issuer’s Class A Common Stock.

On April 28, 2022 (the “Separation Agreement Date”), as more specifically described in Item 6, hereinbelow, by virtue of the mutual execution of the Separation Agreement (defined in Item 6, hereinbelow) by Mr. Adcock and the Issuer, the Issuer’s repurchase right was terminated, effective immediately, with respect to the: (i) Unvested Option Shares (defined in Item 6, hereinbelow) directly held by Mr. Adcock and (ii) Unvested Restricted Shares (defined in Item 6, hereinbelow) directly held by Hight Drive. On the Separation Agreement Date, by virtue of the mutual execution of the Separation Agreement by Mr. Adcock and the Issuer, the Founder Grant was caused to be modified so that its vesting period did not terminate and was instead extended by 15 months from the Separation Agreement Date, as more specifically described in Item 6, hereinbelow.
