(c) During our last fiscal quarter, on September 14, 2026, The Gardner 2008 Living Trust (the “Gardner Trust”) along with two trusts established for the benefit of the children of Jason Gardner (the “Children’s Trusts”), adopted an umbrella Rule 10b5-1 trading arrangement providing for the sale from time to time of an aggregate of up to 1,661,000 shares of our Class A Common Stock. The shares held by the Gardner Trust may be deemed to be beneficially owned by Jason Gardner, a member of our board of directors. Jason Gardner disclaims beneficial ownership of the shares held by the Children’s Trusts. The trading arrangement is intended to satisfy the affirmative defense in Rule 10b5-1(c). The duration of the trading arrangement is until November 30, 2027, or earlier if all transactions under the trading arrangement are completed, but in no case earlier than one year, or later than two years, from September 14, 2026. This trading arrangement will not commence until after the termination of the previous trading arrangement by its terms on November 27, 2026.

No other officers, as defined in Rule 16a-1(f), or directors adopted orterminated a Rule 10b5-1 trading arrangement or a “non-Rule 10b5-1 trading arrangement,” as defined in Item 408 of Regulation S-K, during our last fiscal quarter.
