The securities to which this Schedule relates (the "Securities") are owned by certain investment limited partnerships for which Whale Rock Capital Management LLC ("Whale Rock") serves as investment manager. Whale Rock, as those investment limited partnerships' investment manager, and Alexander Sacerdote, as managing member and owner of Whale Rock, may therefore be deemed to beneficially own Securities owned by such investment limited partnerships for the purposes of Rule 13d-3 of the Securities Exchange Act of 1934, as amended (the "Act"), insofar as they may be deemed to have the power to direct the voting or disposition of those Securities.

Neither the filing of this Schedule nor any of its contents shall be deemed to constitute an admission that Whale Rock or Alexander Sacerdote is, for any other purpose, the beneficial owner of any of the Securities, and each of Whale Rock and Alexander Sacerdote disclaims beneficial ownership as to the Securities, except to the extent of his or its pecuniary interests therein.

Under the definition of "beneficial ownership" in Rule 13d-3 under the Act, it is also possible that the individual general partners, executive officers, and members of the foregoing entities might be deemed the "beneficial owners" of some or all of the Securities insofar as they may be deemed to share the power to direct the voting or disposition of the Securities. Neither the filing of this Schedule nor any of its contents shall be deemed to constitute an admission that any of such individuals is, for any purpose, the beneficial owner of any of the Securities, and such beneficial ownership is expressly disclaimed.

The calculation of percentage of beneficial ownership in Item 11 was derived from (i) the Issuer's Form 8-K for the month of June, 2025, as filed with the Securities and Exchange Commission on July 17, 2025, in which the Issuer stated that there are 114,991,980 shares of Subordinate Voting Shares outstanding.</sharedPowerOrDirectToDispose>
