Class II director; elected November 9, 2025 when the board increased its size from eleven to twelve to fill a newly created directorship; term holds until the 2028 Annual Meeting. Independent non-employee director per the Item 5.02 8-K filed November 13, 2025. Compensation: a $350,000 grant-date-fair-value option award under the 2020 Equity Incentive Plan, vesting 12.5% quarterly over two years; no cash compensation. The 8-K does not include a biographical summary; per contemporaneous reporting Mr. Clayville's most recent operating roles were senior enterprise-sales leadership positions at AWS and Stripe.

Disclosed in the Item 5.02 8-K filed June 16, 2026 (event date June 11, 2026). Snabe took a leave of absence from the board and as special advisor to the CEO in connection with his appointment as Special Envoy to the European Commission for Industrial Artificial Intelligence. During the leave he does not vote or perform board or advisor duties; he will not stand for re-election at the 2026 annual meeting but is expected to return after the leave (duration undetermined). The board reduced its size from twelve to eleven effective the day after the effective date. This is a leave / role-pause, not a clean departure — the row will be updated if he returns or formally exits.

Disclosed in the Item 5.02 8-K filed May 12, 2026 (event date May 8, 2026), announced alongside preliminary Q4 / FY2026 results. Siebel had initiated the CEO search in July 2025 after an autoimmune-disease diagnosis (giant cell arteritis) that caused visual impairment; in returning he said his vision was improving and the 2025 health issues were "largely resolved." Stephen Ehikian, CEO since September 1, 2025, became President and now reports to Siebel.

Named in the August 2025 proxy's executive-officer table as Executive Vice President and Chief Commercial Officer (age 56, in the role since June 2025). He last appears in an SEC filing as a serving officer in the Q2 FY2026 10-Q filed December 9, 2025, whose Rule 10b5-1 trading-arrangements table lists him by title. He is absent from c3.ai/leadership/ and from the investor-relations executive-management roster, and the FY2026 10-K names no Chief Commercial Officer.

C3.ai filed no Item 5.02 8-K, which an EVP-level officer's departure does not require — that item covers the principal executive, financial, and accounting officers, the president, and directors. Archived copies of the company's leadership page still carried him on February 9, 2026 and no longer did on April 15, 2026, which brackets the departure around the February 24, 2026 restructuring without confirming a connection. Where he went next has not been announced. The row will be updated when the next proxy or a company statement makes the date and destination explicit.

Disclosed in the Item 5.02 8-K filed September 5, 2025. The transition was the first CEO change in the company's 16-year history. Siebel did not retire — he continued as Executive Chairman and remained a Section 16 reporting officer; the change was structurally an ownership-and-governance continuity move, not a clean exit. Nine months later he resumed the CEO role (see the May 8, 2026 row above).
