Ceribell CEO Xingjuan Chao sells 39,000 shares for $776,100 on 2026-07-07 via 10b5-1 plan

Xingjuan Chao, President and CEO of Ceribell, executed 3 separate sales totaling 39,000 shares for $776,100.00 at $19.90 per share on 2026-07-07, reducing non-derivative holdings to 802,317 shares (-4.6% vs pre-transaction). This transaction is part of a pre-arranged 10b5-1 trading plan and therefore scheduled rather than discretionary. The CEO maintains derivative holdings of 366,633 shares (288,710 stock options and 77,923 stock options), preserving significant upside exposure. Ceribell trades at $19.47, down 20.0% from its 52-week high of $24.33, while the company posted a quarterly revenue of $26,494,000.00 with a net loss of $19,737,000.00 and remains unprofitable on a full-year basis—context that frames this sale as part of an established trading schedule rather than a reaction to current market conditions.

TPG GP A, LLC sold 202,368 shares of CBLL at $20.12 for $4.1M; stock now at $19.45, down 20.1% from 52-week high.

TPG GP A, LLC sold 202,368 shares at $20.12 on 2026-06-26, representing a 5.1% reduction in holdings to 3,765,054 shares post-transaction. The stock has declined 20.1% from its 52-week high of $24.33, though it has gained 5.4% over the past 30 days. Across the insider's cross-ticker trading history, prior sells averaged a 90-day return of +71.3%, with a well-timed rate of only 25.00%, indicating those previous sales generally occurred before rallies rather than selloffs. At CBLL specifically, the insider's single prior trade was a buy on 2024-10-15 that delivered +62.1% over 30 days and +22.6% over 90 days. The company remains unprofitable with net income of $-19,737,000.00 on revenue of $26,494,000.00 in the latest quarter, though annual revenue growth reached +36.1%.

CBLL CEO Xingjuan Chao sells 39,000 shares for $714,870.00 via scheduled 10b5-1 plan

Xingjuan Chao, President and CEO of Ceribell, Inc., executed 3 separate sales totaling 39,000 shares for $714,870.00 on 2026-06-08 at $18.33 per share under a pre-arranged 10b5-1 trading plan, reducing non-derivative holdings to 816,317 shares. The transaction is scheduled rather than discretionary, removing timing as an interpretive variable. The company reported a net loss of $19,737,000.00 on revenue of $26,494,000.00 in its latest quarter and remains unprofitable on a full-year basis, despite annual revenue growth of +36.1%. The current stock price of $18.63 sits 23.4% below its 52-week high of $24.33 and down 7.1% over 30 days. The CEO retains 391,633 shares in derivative holdings (stock options), preserving meaningful economic exposure.

Significance 4

Ceribell CEO sells ~$783k in shares as stock trades well below recent highs; unprofitable company with strong revenue growth.

Chao Xingjuan, Ceribell's President and CEO, sold approximately $783,973 in shares on a single date through five separate transactions, representing about 4.5% of his holdings. The stock is currently trading well below its recent highs and has remained flat over the past quarter, creating an unfavorable backdrop for equity sales. Notably, Chao's prior sales in this same stock have shown consistently poor timing — the stock rose modestly to meaningfully after each of his previous exits, meaning he has missed gains on every prior occasion. Adding to the headwind, Ceribell remains unprofitable on a net income basis despite strong revenue growth, which suggests the company is in a capital-intensive or competitive phase where operational results remain deeply negative. This sale from the CEO lacks the conviction signal one might expect from a company insider and instead reads as straightforward portfolio activity in a struggling stock.

This transaction is part of a pre-arranged 10b5-1 trading plan and therefore scheduled, not discretionary. The sale represents a 4.4% reduction in pre-transaction holdings at a blended average price of $18.40 per share. As a scheduled disposition under a pre-arranged plan, this sale carries no inference regarding current market timing or near-term strategic positioning.

Ceribell CEO Chao Xingjuan sells 39,000 shares for $680,564.46 via pre-arranged 10b5-1 plan

Chao Xingjuan, President and CEO, executed 3 separate sales totaling 39,000 shares (39.0K shares) for $680,564.46 at a blended average price of $17.45 on 2026-03-03.

Post-transaction, Chao retains 711,164 shares (711.2K shares), representing a reduction of 5.2% from pre-transaction holdings. Since the trade was executed under a pre-arranged trading plan, the timing and execution reflect plan mechanics rather than spontaneous insider decision-making around current market conditions.

CEO Chao Xingjuan sold 39,000 shares at $20.16 for $786,240 on 2026-02-04; stock down 21.1% from 52-week high

Chao Xingjuan, the President and CEO, executed 3 separate sales totaling 39,000 shares (39.0K shares) for $786,240.00 ($786.2K), reducing his holdings from 766,248 shares (766.2K shares) to 727,248 shares (727.2K shares). The sales occurred at $20.16, which is 0.05 below the current price of $20.15, and represent a sale point -21.1% below the 52-week high of $25.54. Ceribell remains unprofitable on a full-year basis with a net income of $-13,465,000.00 ($-13.5M) in the latest quarter against revenue of $22,589,000.00 ($22.6M), though annual revenue growth stands at +44.7%. His prior three sales at CBLL on 2026-01-05 each showed negative 30-day returns (-5.4%, -5.0%, -4.8%), while the stock is currently -11.7% over 30 days from the transaction date. The timing pattern across his same-ticker history shows no measurable well-timed outcomes at the 90-day horizon.

CBLL CEO Chao Xingjuan sells 79,000 shares ($1.7M) at $21.27 blended avg; retains 741.2K shares post-trade

Chao Xingjuan, President and CEO of Ceribell Inc., executed 3 separate sales totaling 79,000 shares for $1,680,047.84 at a blended average price of $21.27 on 2026-01-05. The disposition reduced his holdings by 9.6% to 741,248 shares remaining. Against the current price of $22.83, the insider sold at a 5.8% discount to today's market, and the stock has rallied 12.9% over 30 days and 78.1% over 90 days—a strong price trajectory that occurred after the sale. Ceribell remains unprofitable with net income of $-13,465,000.00 against $22,589,000.00 in quarterly revenue, despite 44.7% annual revenue growth; the $846.9M market cap reflects a high-growth but loss-making profile. The insider's cross-ticker track record shows 1 prior sell with a +40.1% 30-day return, and his prior CBLL trade (a sell on 2025-11-21) also returned +40.1% at 30 days, suggesting a pattern of selling ahead of near-term strength rather than into weakness.

Significance 5

CFO Scott Blumberg sold 36,000 shares at $21.00 for $756,000.00 via 10b5-1 plan; holding reduced 23.2%.

Blumberg, CFO of Ceribell Inc., executed three separate sales totaling 36,000 shares for $756,000.00 under a pre-arranged 10b5-1 trading plan on 2025-12-22. His post-transaction holdings stand at 118,842 shares, representing a net reduction of 23.2% versus his pre-transaction position of 154,842 shares. Because this transaction is scheduled under a 10b5-1 plan rather than discretionary, the timing is predetermined and does not reflect real-time market assessment. The magnitude of the position reduction—over one-fifth of his holdings—combined with the structured nature of the sale plan, provides minimal insight into his contemporaneous conviction regarding the company's prospects.
