Securities Trading Plans of Directors and Executive Officers

During our last fiscal quarter, the following directors and officers, as defined in Rule 16a-1(f), adopted a “Rule 10b5-1 trading arrangement” as defined in Regulation S-K Item 408, as follows:

On February 28, 2024, Karen Peacock, amember of our Board of directors adopted a Rule 10b5-1 trading arrangement providing for the sale from time-to-time of an aggregate of up to 10,000 shares of our Class A common stock. The trading arrangement is intended to satisfy the affirmative defense in Rule 10b5-1(c). The duration of the trading arrangement is until December 31, 2024, or earlier if all transactions under the trading arrangement are completed.

On March 11, 2024, Eric Cox, our Chief Customer Officer, adopted a Rule 10b5-1 trading arrangement providing for the sale from time-to-time of an aggregate of up to 21,436 shares of our Class A common stock, although we expect the total number of such shares sold will ultimately be less than this amount due to withholding for applicable taxes. The trading arrangement is intended to satisfy the affirmative defense in Rule 10b5-1(c). The duration of the trading arrangement is until August 29, 2025, or earlier if all transactions under the trading arrangement are completed.

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