Executive Chair and 10% owner sold shares under a 10b5-1 plan; ongoing large indirect holdings remain.

The Executive Chairman, a 10% owner and director, reported selling 543,706 shares of C3.ai Class A on 11/11/2025 under a pre-established Rule 10b5-1 plan dated September 20, 2024. The sale used a weighted-average price of $15.24 across trades executed between $14.91 and $15.59. This indicates a programmed transaction rather than discretionary timing.

Post-transaction, significant indirect beneficial ownership remains across multiple entities: 1,437,174 shares via a living trust; 9,216 via First Virtual Holdings, LLC; 170,294 via Siebel Asset Management, L.P.; 72,695 via Siebel Asset Management III, L.P.; and 1,237,115 via a 2011 irrevocable children's trust. The price disclosure is weighted-average; detailed trade-level prices are available upon request.

Key items to watch: any subsequent Form 4s under this plan, changes in the plan, or shifts in indirect holdings. The plan-based nature frames the activity as scheduled; monitoring through the next filings cycle after 11/2025 will clarify cadence and size of further programmed sales.
