Securities Trading Plans of Directors and Executive Officers

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

On March 13, 2025, Vladimir Shmunis, our Chairman and Chief Executive Officer, adopted a Rule 10b5-1 trading arrangement providing for the sale from time to time of up to 331,122 shares of Class A common stock expected to be received upon vesting of outstanding RSUs and PSUs (the “March 2025 Trading Plan”). The number of shares that may be sold under the March 2025 Trading Plan may also be increased by the number of shares of Class A common stock, if any (not yet determinable), that are awarded to Mr. Shmunis under the Company’s employee equity bonus and executive equity compensation plans. The number of shares that may be sold under the March 2025 Trading Plan will be reduced by the number of shares (not yet determinable) withheld to satisfy tax obligations upon the vesting of certain outstanding equity awards. The March 2025 Trading Plan is intended to satisfy the affirmative defense in Rule 10b5-1(c). The March 2025 Trading Plan goes into effect, with respect to any potential trading activity, following the expiration of Mr. Shmunis’ current 10b5-1 trading arrangement, which was entered into on March 15, 2023 (the “March 2023 Trading Plan”), and the duration of the trading arrangement is until March 31, 2026 or earlier if all transactions under the trading arrangement are completed. The March 2025 Trading Plan does not modify or terminate the March 2023 Trading Plan in any respect and the timing of any trading activity under the two plans does not overlap.

The March 2023 Trading Plan provides for the sale from time to time of up to 213,721 shares of Class A common stock. The number of shares that may be sold under the March 2023 Trading Plan includes shares of Class A common stock that are awarded to Mr. Shmunis under the Company’s employee equity bonus and executive equity compensation plans. The number of shares that may be sold under the March 2023 Trading Plan will be reduced by the number of shares (not yet fully determinable) withheld to satisfy tax obligations upon the vesting of certain outstanding equity awards. The March 2023 Trading Plan is intended to satisfy the affirmative defense in Rule 10b5-1(c). The duration of the trading arrangement is until May 30, 2025 or earlier if all transactions under the trading arrangement are completed.

On March 14, 2025, Kira Makagon, our President and Chief Operating Officer, adopted a Rule 10b5-1 trading arrangement providing for the sale from time to time of up to 185,305 shares of Class A common stock. The number of shares that may be sold under the trading arrangement may also be increased by the number of shares of the company’s Class A common stock, if any (not yet determinable) that are awarded to Ms. Makagon under the company’s employee equity bonus and executive equity compensation plans. The number of shares that may be sold under the trading arrangement will be reduced by the number of shares (not yet determinable) withheld to satisfy tax obligations upon the vesting of certain outstanding equity awards. The trading arrangement is intended to satisfy the affirmative defense in Rule 10b5-1(c). The duration of the trading arrangement is until June 30, 2026 or earlier if all transactions under the trading arrangement are completed.

On March 14, 2025, Tarun Arora, our Chief Accounting Officer, adopted a Rule 10b5-1 trading arrangement providing for the sale from time to time of up to 43,247 shares of Class A common stock. The number of shares that may be sold under the trading arrangement may also be increased by the number of shares of the company’s Class A common stock, if any (not yet determinable) that are awarded to Mr. Arora under the company’s employee equity bonus and executive equity compensation plans. The number of shares that may be sold under the trading arrangement will be reduced by the number of shares (not yet determinable) withheld to satisfy tax obligations upon the vesting of certain outstanding equity awards. The trading arrangement is intended to satisfy the affirmative defense in Rule 10b5-1(c). The duration of the trading arrangement is until June 18, 2026 or earlier if all transactions under the trading arrangement are completed.

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