| Trading Arrangements, by Individual | |
| Material Terms of Trading Arrangement | On November 26, 2025, Chris Urmson, Chief Executive Officer of the Company, terminated a Rule 10b5-1 trading plan adopted on March 11, 2025 (the "Terminated Plan"). No sales have been triggered under the Terminated Plan as of the termination date. On December 11, 2025, Mr. Urmson adopted a new Rule 10b5-1 trading plan providing for the sale from time to time of an aggregate of up to 5.0 million shares of our Class A common stock, i.e., the number of shares of Class A common stock that was not sold pursuant to the Terminated Plan. The new trading arrangement is intended to be a continuation of the Terminated Plan, with the first trade under the new plan to occur as early as May 26, 2026 and to satisfy the affirmative defense in Rule 10b5-1(c). The duration of the new trading arrangement is until May 26, 2027, or earlier if all transactions under the trading arrangement are completed. Immediately prior to entering into this plan, Mr. Urmson was the beneficial owner of a total of 146,587,491 derivative and non-derivative securities (the "Original Holdings"), consisting of 140,831,739 shares of Class B common stock and 5,755,752 shares of Class A common stock. In the event that the maximum number of shares covered by the trading plan are sold, he will continue to beneficially own approximately 97% of the Original Holdings. |
