Provide the following information regarding the aggregate number and percentage of the class of securities of the Issuer identified in Item 1.

Reference to “beneficial ownership” of securities for purposes of this statement shall be understood to refer to beneficial ownership as that term is defined in Rule 13d-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

As of December 31, 2022, the Reporting Persons may be deemed to directly or indirectly beneficially own an aggregate total of 13,687,366 shares of the Issuer’s Class A Common Stock.

As of December 31, 2022, Mr. Weingarten was deemed to be the direct beneficial owner of 13,151,292 of the securities described in the preceding paragraph. The aforementioned direct beneficial ownership consists of: (i) 4,235,079 shares of the Issuer’s Class B Common Stock, which are convertible into shares of the Issuer’s Class A Common Stock on a one-for-one basis at any time upon the election of the holder or automatically upon certain transfers, whether or not for value, or upon the occurrence of certain other events more specifically described in the Issuer’s Ninth Amended and Restated Certificate of Incorporation; (ii) an aggregate 3,244,126 vested stock options which are exercisable for an equal number of shares of the Issuer’s Class B Common Stock and convertible on a one-for-one basis into Class A Common Stock; (iii) an aggregate 333,281 stock options which shall vest and become exercisable within 60 days of December 31, 2022, which, once vested, are exercisable for an equal number of shares of the Issuer’s Class B Common Stock and convertible on a one-for-one basis into Class A Common Stock; (iv) 19,956 restricted stock units which shall vest and be settled for an equal number of shares of the Issuer’s Class A Common Stock within 60 days following December 31, 2022; and (v) the sole power to vote, or to direct the vote of, 5,318,850 shares (the “Proxy Shares”) of the Issuer’s Class A Common Stock held by Mr. Almog Cohen (“Mr. Cohen”), pursuant to an Irrevocable Proxy Agreement (the “Proxy Agreement”) dated June 17, 2021, entered into by and between Mr. Cohen, as the owner of the Proxy Shares, and Mr Weingarten. Pursuant to the Proxy Agreement, Mr. Cohen granted Mr. Weingarten an irrevocable proxy to vote, in Mr. Weingarten’s discretion, and except under limited circumstances, all of the Issuer’s securities beneficially owned by Mr. Cohen on all matters submitted to a vote of the Issuer’s stockholders. To the best of the Reporting Persons’ knowledge, the Proxy Agreement does not give rise to the formation of a “group” between the Reporting Persons, on the one hand, and Mr. Cohen, on the other hand, pursuant to Section 13(d) of the Exchange Act. Additionally, for the avoidance of doubt, Mr. Weingarten does not have any pecuniary interest in, and has no dispositive power over, the Proxy Shares, and the filing of this statement shall not be construed as an admission that any of the Reporting Persons is, for purposes of Sections 13(d) or 13(g) of the Exchange Act, Section 16 of the Exchange Act, or for any other purpose, the beneficial owner of any securities owned by Mr. Cohen, or vice versa.

As of December 31, 2022, the GRAT was the direct beneficial owner of 136,074 shares of the Issuer’s Class A Common Stock described in the second paragraph of this Item 4(a), which securities consist of 136,074 shares of the Issuer’s Class B Common Stock directly held by the GRAT, and which are convertible into an equal number of shares of the Issuer’s Class A Common Stock. Mr. Weingarten is the sole trustee of the GRAT. As such, Mr. Weingarten may be deemed to have indirect beneficial ownership of the securities directly beneficially owned by the GRAT.

As of December 31, 2022, the Irrevocable Trust was the direct beneficial owner of 400,000 shares of the Issuer’s Class A Common Stock described in the second paragraph of this Item 4(a), which securities consist of 400,000 shares of the Issuer’s Class B Common Stock held by the Irrevocable Trust, and which are convertible into an equal number of shares of the Issuer’s Class A Common Stock. North Point Trust Company, LLC (the “Trustee”) is the sole trustee of the Irrevocable Trust. As such, the Trustee may be deemed to have indirect beneficial ownership of securities directly beneficially owned by the Irrevocable Trust.

Mr. Weingarten expressly disclaims beneficial ownership of the 400,000 shares of the Issuer’s Class B Common Stock directly owned by the Weingarten 2021 Irrevocable Trust dated April 29, 2021 (the “Irrevocable Trust”). The Irrevocable Trust and its Trustee may be deemed to be a “group” with the other Reporting Persons for purposes of Section 13(d) of the Exchange Act due to Mr. Weingarten’s authority to replace the Trustee. Notwithstanding such authority, the filing of this statement shall not be construed as an admission that (i) Mr. Weingarten and the GRAT, on the one hand, or (ii) the Trustee and the Irrevocable Trust, on the other hand, is or has been, for the purposes of Sections 13(d) or 13(g) of the Exchange Act, Section 16 of the Exchange Act, or for any other purpose, the beneficial owner of the securities reported in this statement as being owned by the other party, and each Reporting Person disclaims beneficial ownership of such securities pursuant to Rule 13d-4.

As of December 31, 2022, the Reporting Persons were deemed to directly or indirectly beneficially own an aggregate total of 6.2% of the Issuer’s outstanding Class A Common Stock. Of that percentage, beneficial ownership was attributable as follows: (i) 6.0%, directly to Mr. Weingarten; (ii) 0.1%, directly to the GRAT and indirectly to Mr. Weingarten as its trustee; and (iii) 0.2%, directly to the Irrevocable Trust and indirectly to the Trustee.

The aforementioned percentages were calculated in accordance with Rule 13(d)-3(d)(1)(i), promulgated under the Exchange Act, and based on an aggregate total of 214,930,632 shares of the Issuer’s Class A Common Stock outstanding as of December 2, 2022, as reported by the Issuer in its Quarterly Report for the period ended October 31, 2022, filed on Form 10-Q with the Securities and Exchange Commission on December 6, 2022.

If this statement is being filed to report the fact that as of the date hereof the reporting person has ceased to be the beneficial owner of more than 5 percent of the class of securities, check the following ¨.

The owner of record of the Proxy Shares retains the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of the Proxy Shares. None of the Reporting Persons has any right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of the Proxy Shares.
