C3.ai CEO Siebel Sells 462,565 Shares After 66% Price Drop
C3.ai CEO Thomas Siebel cashed out nearly a fifth of his total equity holdings as the enterprise AI software firm's stock suffered a 66% one-year decline.
Thomas M. Siebel, CEO and Chairman of C3.ai, exercised options to acquire and immediately sold 462,565 shares of the company’s Class A Common Stock over July 14 and July 15, 2026. The transactions, detailed in a recent SEC Form 4 filing, were executed at a weighted average price of $9.18 per share. By exercising the options at a $3.90 strike price, Siebel locked in a profit of $5.28 per share.
The sale reduced the executive's total equity holdings by approximately 17%. However, Siebel remains a substantial shareholder, retaining 2,216,684 total beneficial shares. This remaining stake represents roughly 1% of the enterprise AI software provider.
This divestment arrives during a period of steep deterioration in C3.ai’s market valuation. The stock has recorded a negative 66% total return over the past year, closing at $9.14 on July 15. For market participants, a CEO liquidating a sizable portion of equity while the stock languishes near multi-year lows raises questions about internal confidence. Even when framed as a routine options exercise, the decision to harvest gains rather than hold the underlying shares can be interpreted as a bearish signal by institutional investors.
Siebel’s ongoing financial ties to the company remain heavily weighted through derivative securities. He continues to hold approximately 2.9 million derivative securities directly. Additionally, his indirect control covers about 1.5 million shares distributed across four distinct entities. The largest of these is The Siebel 2011 Irrevocable Children's Trust, which accounts for roughly 1.2 million shares. Smaller indirect holdings are managed through Siebel Asset Management, Siebel Asset Management III, and First Virtual Holdings.
C3.ai generates its revenue through a subscription-based software-as-a-service model. The firm licenses its core C3 AI Application Platform, alongside specialized tools like C3 AI Ex Machina and C3 AI CRM, to large global enterprises. While the broader artificial intelligence sector continues to attract significant capital, C3.ai’s recent stock performance indicates the market is currently prioritizing profitability and scale over early-stage enterprise adoption narratives. The CEO's recent stock sale underscores the disconnect between the company's foundational AI technology and its current Wall Street valuation.
