Election of Director On November 9, 2025, the board of directors (the “Board”) of C3.ai, Inc. (the “Company”) increased the number of directors constituting the full Board from eleven to twelve and elected Mike Clayville to the Board to fill the newly created directorship, effective immediately. Mr. Clayville was elected as a Class II director to hold office until the Company’s 2028 Annual Meeting of Stockholders and until his successor has been duly elected and qualified or until his earlier death, resignation, or removal. Consistent with its compensation for directors generally, Mr. Clayville will receive options to purchase shares of Class A common stock but will not receive any cash compensation for his service on the Board. As a newly elected director, Mr. Clayville will receive an award of options to purchase shares of Class A Common Stock under the Company's Amended and Restated 2020 Equity Incentive Plan, as amended (the “2020 Plan”), having an aggregate grant date fair value of $350,000 and an exercise price equal to the fair value of the Company’s common stock on the grant date. This option award vests over two years, with 12.5% of the shares subject to the award vesting quarterly after the date of grant, provided Mr. Clayville remains as a non-employee director and attends the regularly scheduled meeting of the board of directors during each fiscal quarter commencing following such grant. This option award vests in full upon a change in control (as defined in the 2020 Plan), subject to Mr. Clayville remaining in service until the closing of the change in control. There is no arrangement or understanding between Mr. Clayville and any other persons pursuant to which he was elected as a director.
