Each share of Class B Common Stock is convertible into one share of Class A Common Stock at any time and will convert automatically upon certain transfers and upon the earlier of (i) the date specified by a vote of the holders of 66 2/3% of the then outstanding shares of Class B Common Stock, (ii) seven years from the effective date of the IPO (as defined in the Schedule 13D), (iii) the first date following the IPO on which the number of shares of outstanding Class B Common Stock (including shares of Class B Common Stock subject to outstanding stock options) held by Tomer Weingarten, including certain entities that Mr. Weingarten controls, is less than 25% of the number of shares of Class B Common Stock (including shares of Class B Common Stock subject to outstanding stock options) that Mr. Weingarten originally held as of the date of the IPO, (iv) the date fixed by the Issuer’s board of directors (the “Board”), following the first date following the completion of the IPO when Mr. Weingarten is no longer providing services to the Issuer as an officer, employee, consultant or member of the Board, (v) the date fixed by the Board following the date, if applicable, on which Mr. Weingarten is terminated for cause, as defined in the Issuer’s restated certificate of incorporation, and (vi) the date that is 12 months after the death or disability, as defined in the Issuer’s restated certificate of incorporation, of Mr. Weingarten.

(2)
Based on the quotient obtained by dividing (a) the aggregate number of shares of Class A Common Stock and Class B Common Stock beneficially owned by the Reporting Person, by (b) the sum of (i) 134,523,732 shares of Class A Common Stock outstanding as of November 30, 2021, as reported in the 10-Q, and (ii) the number of shares of Class B Common Stock beneficially owned by the Reporting Persons. The number of shares of Class B Common Stock beneficially owned by the Reporting Person(s) are treated as converted into Class A Common Stock only for the purpose of computing the percentage ownership of the Reporting Person for the purpose hereof.

(3)
The Class B Common Stock has 20 votes per share, and the Class A Common Stock has one vote per share.  The percentage ownership of the Reporting Person reported herein does not give effect to the 20 votes per share of Class B Common Stock because the shares of Class B Common Stock are treated as converted into Class A Common Stock for the purpose hereof.

On the date hereof, the Reporting Persons beneficially own an aggregate of 3,646,919 shares of Class A Common Stock and 30,999,311 shares of Class B Common Stock, which represent approximately 20.9% of the Class A Common Stock outstanding (calculated in accordance with footnote (2) above).  If all outstanding shares of Class B Common Stock (as reported in the 10-Q) were deemed converted into Class A Common Stock, the Reporting Persons would be deemed to beneficially own approximately 13.0% of the shares of Class A Common Stock deemed outstanding.

Each of the Reporting Persons shares voting and dispositive power over the shares of Class A Common Stock and Class B Common Stock held directly by the IVP X Funds, IP XI Funds and IP X FOF Funds.

Each of Holdings, IVA X Ltd, IA XI Ltd, IA X FOF Ltd, IVA X, IA XI, IA EU XI and IA X FOF expressly declares that nothing herein shall be construed as an admission that it is, for the purposes of sections 13(d) or 13(g) of the Act or for any other purpose, the beneficial owner of any securities covered hereby.

To the Reporting Persons’ knowledge, no shares of Class A Common Stock or Class B Common Stock are beneficially owned by any Scheduled Person (as defined in the Schedule 13D).

Item 6.
Contracts, Arrangements, Understandings, or Relationships With Respect to Securities of the Issuer.

Item 6 of the Schedule 13D is amended as follows:

Certain of the Reporting Persons are party to the following contracts with respect to the securities of the Issuer:

Lock-Up Agreements

In connection with the IPO, the IVP X Funds, IP XI Funds and IP X FOF Funds entered into Lock-Up Agreements with the underwriters pursuant to which such Reporting Persons, with limited exceptions, agreed to not, without the prior written consent of Morgan Stanley & Co. LLC and Goldman Sachs & Co. LLC, or their representatives, transfer shares of common stock of the Issuer, including any hedging transactions, during the period ending on the earlier of (i) the opening of trading on the second trading day immediately following the Issuer’s public release of earnings for the third quarter of fiscal 2022 and (ii) the date that is 180 days after the date of the Prospectus (as defined in the Schedule 13D).

Following the Issuer’s public release of its quarterly financial results for the third quarter of its fiscal year ending January 31, 2022, as reported in the Issuer’s current report on Form 8-K, as filed with the SEC on December 7, 2021 (the “8-K”), immediately prior to the opening of trading on December 9, 2021, the transfer restrictions to which the shares of the Issuer’s common stock were subject under the Lock-Up Agreements expired and such shares became eligible for sale, subject to the restrictions described in Item 8.01 of the 8-K, incorporated herein by reference.

The foregoing description of the Lock-Up Agreements is a summary only and is qualified in its entirety by reference to the form of Lock-Up Agreement, which is filed as Exhibit 7.2 herewith and incorporated by reference herein.

Investors’ Rights Agreement

Pursuant to the Sixth Amended and Restated Investors’ Rights Agreement, dated as of October 28, 2020, by and among the Issuer, the IVP X Funds, the IP XI Funds and certain other holders listed therein (the “Investors’ Rights Agreement”), such Reporting Persons are entitled to certain registration rights in connection with the resale of the shares of capital stock of the Issuer owned or acquired by such Reporting Persons (the “Registerable Securities”), including customary demand registration rights, piggy-back registration rights and a re-sale shelf-registration statement covering the Registerable Securities.

The foregoing description of the Investors’ Rights Agreement is a summary only and is qualified in its entirety by reference to the Investors’ Rights Agreement, which is filed as Exhibit 7.3 herewith and incorporated by reference herein.

The information set forth, or incorporated by reference, in Items 3 through 5 is hereby incorporated by reference into this Item 6.  Except as described herein, there are no contracts, arrangements, undertakings or relationships (legal or otherwise) among the persons named in Item 2 (or any Scheduled Person) or between such persons and any other person with respect to any securities of the Issuer.

Item 7. Material to Be Filed as Exhibits.

Exhibit 7.1
Joint Filing Agreement, dated July 12, 2021, by and among the Reporting Persons (incorporated by reference to Exhibit 7.1 to the Schedule 13D filed on behalf of the Reporting Persons with the SEC on July 12, 2021).
 
Exhibit 7.2
Form of Lock-Up Agreement (incorporated by reference to Exhibit A to Exhibit 1.1 to Amendment No. 2 to Form S-1 filed by the Issuer with the SEC on June 28, 2021).
 
Exhibit 7.3
