(c)Insider Trading Arrangements and Policies

The Company’s directors and officers (as defined in Rule 16a-1(f) under the Exchange Act) are only permitted to trade in the Company’s securities pursuant to a prearranged trading plan intended to satisfy the affirmative defense of Rule 10b5-1(c) under the Exchange Act (a Rule 10b5-1 Plan). During the three months ended July 31, 2025, one of our Section 16 officers adopted a new Rule 10b5-1 Plan. The Weingarten Plan (as defined below) was entered into during an open trading window in accordance with our Insider Trading Policy.

On June 3, 2025, Tomer Weingarten, our President and Chief Executive Officer, adopted a Rule 10b5-1 Plan (the Weingarten Plan) providing for the potential sale of: (i) 753,243 shares of our Class A common stock issuable upon the conversion of shares of Class B common stock and (ii) certain shares of our Class A common stock which may be received by Mr. Weingarten upon vesting and settlement of certain outstanding restricted stock units and performance stock units, net of any shares withheld by the Company to satisfy applicable tax obligations, with such sales occurring between an estimated start date of September 11, 2025 and an estimated end date of September 15, 2026. The number of shares to be withheld, and therefore the exact number of shares to be sold pursuant to the Weingarten Plan, can only be determined upon the occurrence of the future vesting events. The Weingarten Plan is scheduled to expire on September 15, 2026.
