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 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.

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).
