Trading Arrangements, by Individual |  |
Material Terms of Trading Arrangement |  | On September 14, 2023, Mr. Yuann adopted a new trading plan that is intended to satisfy the affirmative defense conditions of Rule 10b5-1 of the Exchange Act as currently in effect (the Yuann Trading Plan). The Yuann Trading Plan has a duration of December 15, 2023 to December 31, 2024 and provides for the sale of up to approximately 390,755 shares of the Company’s Class A common stock (assuming the vesting of shares under certain performance-based restricted stock unit awards (PSUs) at 100% of target), including upon the vesting and settlement of certain equity awards. Because the aggregate number of shares that may be sold under the Yuann Trading Plan (i) will be net of shares withheld by the Company to satisfy Mr. Yuann’s tax obligations upon the vesting and settlement of certain equity awards and (ii) includes shares that may be issued in respect of PSUs, the precise number of shares that may be sold under the Yuann Trading Plan is not yet determinable.
