AI C3.ai, Inc. Insider Trading

C3.ai CEO Siebel sells 462,565 shares for $4,244,431.05 via 10b5-1 plan; stock down 70.4% from 52-week high.

Thomas M Siebel, CEO and Chairman, executed 3 separate sales totaling 462,565 shares for $4,244,431.05 at blended average price $9.18, reducing his non-derivative holdings by -39.0% to 722,362 shares. This transaction is scheduled under a pre-arranged 10b5-1 trading plan, not a discretionary decision. The company faces significant headwinds: C3.ai reported revenue of $53,260,000.00 for the latest quarter but net income of $-133,363,000.00, with annual revenue declining -35.7% year-over-year. Stock price has fallen 70.4% from its 52-week high of $30.11 and currently trades at $8.91, down 18.5% over 30 days. The current market cap of $31,184,928.72 is notably depressed. Siebel retains significant derivative holdings of 2,931,485 shares through stock options, preserving material upside exposure despite the share sales. Investors should note the wide gap between transaction prices ($9.07–$9.32) and current price ($8.91), and the confluence of negative momentum (stock down 70.4% from peak), operational losses, revenue contraction, and ongoing material option holdings.

CEO Thomas M Siebel sold 472.0K shares (39.5% of holdings) at $11.11 under 10b5-1 plan; AI stock -63.4% from 52-week high amid -$133.4M net loss.

Thomas M Siebel, CEO and Chairman, sold 472,005 shares on 2026-06-15 at $11.11 for $5,243,975.55, reducing his holdings from 1,194,367 shares to 722,362 shares. This transaction is part of a pre-arranged 10b5-1 trading plan, meaning it is scheduled rather than discretionary. The sale occurs in a context where C3.ai's stock is down -63.4% from its 52-week high of $30.11 and the company reported a full-year net income of $-133,363,000.00 against revenue of $53,260,000.00, highlighting substantial operating losses. Across Siebel's five prior trades at this ticker, the most measurable outcome shows a 90-day return of +27.2% following a March 2026 sale, but recent sales (May and April 2026) have not yet accumulated 90-day returns; the short-term 30-day performance after those trades has been positive (ranging +4.1% to +25.0%). The scheduled nature of this 10b5-1 trade removes timing as an inference point, and investors should focus on the fundamental disconnect: a highly unprofitable company with a market cap of only $38,604,911.76 whose largest shareholder continues reductions in equity stakes.

C3.ai CEO Siebel sells 481,638 shares at avg $8.70 via pre-arranged plan; stock down 70.8% from 52-week high, company unprofitable.

Thomas M Siebel executed 2 separate sales totaling 481,638 shares for $4,192,042.38 at an average price of $8.70, reducing his holdings by 40.0% from 1,204,000 to 722,362 shares. This transaction is scheduled under a 10b5-1 trading plan and therefore pre-arranged, not discretionary. The stock is trading at $8.83 currently, down 70.8% from its 52-week high of $30.24 and down 16.7% over the prior 90 days, while the company posted a negative net income of $-133,363,000.00 on revenue of $53,260,000.00 in its latest quarter and remains unprofitable on a full-year basis despite 25.3% annual revenue growth. The filing reflects a scheduled divestiture by the CEO during a period of substantial stock depreciation and persistent operational losses.

Siebel (Executive Chairman) sells 491,467 shares at blended $8.37 via scheduled 10b5-1 plan

Thomas M. Siebel executed 2 separate sales totaling 491,467 shares for $4,113,840.81 on April 13–14, 2026, reducing his holdings by 40.5% from 1,213,829 shares to 722,362 shares. This transaction was conducted under a pre-arranged 10b5-1 trading plan, meaning it was scheduled rather than discretionary. The filing reflects a substantial reduction in the Executive Chairman's stake, though the planned nature of the sales precludes any inference about timing or conviction.

Director Snabe executes paired sale/purchase of 10.0K shares each at $8.08 and $7.73 on same day, netting $3.5K gain

Jim H. Snabe completed 1 sale and 1 purchase on 2026-03-27, selling 10,000 shares at $8.08 for $80,800.00 and buying 10,000 shares at $7.73 for $77,300.00 in a single-day paired transaction. The sale executed at a higher price than the purchase, yielding a $3,500.00 net gain on the matched pair. His prior open-market track record shows 2 prior sells with an average 90-day return of -15.5% and a 90-day well-timed rate of 50.0%; at this ticker specifically, his December 2024 sale preceded a 90-day decline of -49.0%. C3.ai is trading at $8.42 current price, down 71.1% from its 52-week high of $29.16, and the company posted a net loss of $-133.4M on revenue of $53.3M in the latest quarter. Post-transaction, Snabe holds 395,000 shares.

Thomas Siebel sells 501,497 shares for $4.4M in two scheduled transactions via 10b5-1 plan

Executive Chairman Thomas M. Siebel executed two separate sales totaling 501,497 shares for $4,401,597.56 ($4.4M) on March 17-18, 2026, at a blended average price of $8.78. These transactions were conducted under a pre-arranged 10b5-1 trading plan, meaning they follow a predetermined schedule rather than discretionary decision-making. Siebel's holdings decreased from 1,223,859 shares to 722,362 shares, representing a reduction of 41.0% of his pre-transaction stake. Because this activity is plan-driven rather than discretionary, the sales do not reflect real-time market judgment or signal a change in conviction about the company's prospects.

Director Snabe bought 25,000 AI shares at $9.00 amid 69.3% decline from 52-week high; stock down 23.1% in 30 days.

Snabe Jim H., a director at C3.ai, purchased 25,000 shares (25.0K shares) at $9.00 on 2026-03-09, increasing his holdings from 370,000 shares to 395,000 shares. The transaction occurs while AI trades at $8.96, down -69.3% from its 52-week high of $29.16 and down -23.1% over the prior 30 days. C3.ai remains unprofitable, posting net income of $-104.7M against quarterly revenue of $75.1M. At a market cap of $31.4M, the company's valuation has compressed significantly. The director's prior sale at this ticker (2024-12-17) was well-timed at the 90-day mark, with the stock declining -49.0% afterward; his cross-ticker record shows mixed results (50.00% well-timed rate on 2 prior sells, with average 90d return of -15.5%). This buy may reflect opportunistic accumulation at a depressed price level, but the company's ongoing unprofitability and recent sharp momentum loss limit conviction signals.

Thomas M Siebel sold 511,732 shares of AI at $11.66 under pre-arranged 10b5-1 plan

Executive Chairman Thomas M Siebel sold 511,732 shares at $11.66 on 2026-02-10 for a total value of $5,966,795.12, reducing his post-transaction holdings to 722,362 shares from 1,234,094 shares (a net reduction of 41.5% vs pre-transaction holdings). This transaction is executed under a pre-arranged 10b5-1 trading plan, meaning it was scheduled in advance rather than discretionary. Since the sale is governed by a pre-established plan rather than responsive to current market conditions or company developments, the trade does not reflect contemporaneous executive judgment about valuation or company prospects. Investors should monitor the execution schedule of this plan to track ongoing dispositions, but the scheduled nature constrains inference about current insider sentiment.

Thomas Siebel sells 522,175 shares at $13.52 via 10b5-1 plan at C3.ai (AI)

Executive Chairman Thomas Siebel completed 2 separate sales totaling 522,175 shares for $7,059,806.00 at $13.52 per share on 2026-01-13, reducing his holdings from 1,154,431 to 632,256 shares (a -45.2% reduction in his pre-transaction stake). This sale was executed under a pre-arranged 10b5-1 trading plan, meaning the timing and sizing were scheduled in advance rather than discretionary decisions made in response to current market conditions. The magnitude of the reduction—nearly half his prior holdings liquidated in a single filing date—represents a material shift in his direct ownership at C3.ai. Without additional context on the plan's original terms or Siebel's concurrent portfolio activity, the scheduled nature of the trades limits inference about current conviction or sentiment toward the company.

Siebel (Executive Chairman) sells 532,832 shares for $7,635,680.64 via scheduled 10b5-1 plan

As a scheduled transaction under 10b5-1 plan mechanics, this sale reflects a predetermined trading arrangement rather than a real-time market decision by the Executive Chairman.
