(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 April 30, 2025, one of our Section 16 officers adopted a new Rule 10b5-1 Plan. The Smith Plan (as defined below) was entered into during an open trading window in accordance with our Insider Trading Policy.

On April 15, 2025, Richard Smith Jr., our President, Product, Technology, and Operations, adopted a Rule 10b5-1 Plan (the Smith Plan) providing for the potential sale of certain shares of our Class A common stock which may be received by Mr. Smith 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 August 7, 2025 and an estimated end date of August 14, 2026. The number of shares to be withheld, and therefore the exact number of shares to be sold pursuant to the Smith Plan, can only be determined upon the occurrence of the future vesting events. The Smith Plan is scheduled to expire on August 14, 2026.
