C3.ai CEO Thomas Siebel Disposes Shares to Cover Tax Withholding
Thomas M. Siebel, CEO and Chairman of C3.ai (NYSE:AI), disposed of 66,752 shares on September 14, 2026, as part of a non-discretionary transaction required by company policy to satisfy tax withholding obligations following the vesting of restricted stock units earlier in the year. The sale included both gifted and directly held shares, with no indication that Siebel made an active decision based on market conditions or confidence levels. Despite this disposal, Siebel remains a major shareholder, owning approximately 9.3 million Class A Common Stock shares and derivative securities worth around $104.1 million as of the transaction date. The stock closed at $11.17 per share that day, with C3.ai's market capitalization standing at $1.7 billion. However, the company has reported a net loss in its trailing twelve months (TTM) and faces challenges reflected by a 38% decline in its one-year total return. The transaction is unlikely to signal any change in Siebel’s long-term commitment or confidence in C3.ai's strategic direction but may be viewed cautiously given the broader context of underperformance.
