PSNL Personalis, Inc. Insider Trading

PSNL President/CMO Chen sells 100,000 shares ($1.5M) via 10b5-1 plan; stock up 61.3% in 30 days as company posts $30M annual loss

Richard Chen sold 100,000 shares (100.0K shares) of Personalis at $15.15 on 2026-07-15 as part of a pre-arranged 10b5-1 trading plan adopted on 2025-12-23, reducing his non-derivative holdings from 273,880 to 173,880 shares (-36.5% vs pre-transaction holdings). The sale occurred amid significant recent stock appreciation—the shares have climbed +61.3% over the prior 30 days and +137.1% over 90 days, bringing current price to $15.79. However, the company's underlying fundamentals remain weak: net income was $-30,032,000.00 ($-30.0M) on annual revenue of $15,472,000.00 ($15.5M), with full-year revenue declining -17.7% year-over-year and the company unprofitable. The scheduled nature of this transaction via a pre-arranged plan removes discretionary timing from the analysis, but the sale's occurrence after recent sharp gains in a fundamentally challenged business presents a potential tension for investors monitoring executive confidence signals.

CEO Hall sells 100,000 PSNL shares at $15.08 under pre-arranged 10b5-1 plan; stock up 50.3% in 30 days but company posts $-30.0M net income.

Christopher M Hall, Personalis' Chief Executive Officer, sold 100,000 shares on 2026-07-09 at $15.08 as part of a pre-arranged 10b5-1 trading plan adopted on 2025-12-17, reducing his non-derivative holdings from 335,986 to 235,986 shares. The sale occurs against a backdrop of mixed signals: the stock has appreciated 50.3% over the past 30 days and 143.4% over 90 days from lows, yet the company remains unprofitable with a net loss of $30,032,000.00 in its most recent quarter and annual revenue contraction of -17.7%, while generating only $15,472,000.00 in latest quarterly revenue. Hall retains 133,333 derivative shares (stock options), indicating his equity stake in the company persists beyond this non-derivative sale. Because this transaction is scheduled under a 10b5-1 plan rather than discretionary, the timing relative to recent price momentum should not be construed as a strategic positioning decision by the CEO.

CFO Aaron Tachibana sells 51,251 shares (20.5% of holding) at $13.18 under pre-arranged 10b5-1 plan

Aaron Tachibana, CFO and COO, sold 51,251 shares at $13.18 on 2026-06-26 as part of a pre-arranged 10b5-1 trading plan adopted on 2025-08-07, reducing his non-derivative holdings to 198,833 shares. This is a scheduled, non-discretionary transaction; timing considerations do not apply. The company faces significant headwinds: Personalis reported a net loss of $-30,032,000 for its most recent full fiscal year, with annual revenue declining 17.7% year-over-year, though the quarterly revenue stands at $15,472,000. The stock has appreciated 37.2% over 30 days and 105.4% over 90 days from depressed levels, trading near its 52-week high of $13.37. Tachibana retains 7,471 stock options (right to buy) in addition to his common shares, indicating an ongoing financial stake in the company's performance.

CEO Christopher M Hall sells 100,000 shares (100.0K shares) at $13.15 via pre-arranged 10b5-1 plan

Christopher M Hall, CEO of Personalis, executed a scheduled sale of 100,000 shares at $13.15 under a pre-arranged 10b5-1 trading plan adopted on 2025-12-17, reducing his non-derivative holdings from 335,986 shares to 235,986 shares. The sale represents a -29.8% reduction in his reported holdings, though he retains 200,000 shares in stock options. This transaction occurs within a context of material operational challenges: the company posted Revenue of $15,472,000.00 (latest quarter) against a Net income of $-30,032,000.00, with Annual revenue growth of -17.7% and a Market cap of $1,363,468,695.96. Hall's two immediately prior sales at PSNL occurred on 2026-05-29 and 2026-05-28 with outcomes not yet measurable. As a scheduled, non-discretionary transaction under 10b5-1 plan rules, this sale's timing reflects pre-established parameters rather than current market conditions; investors should focus on the company's deteriorating profitability and negative revenue trajectory rather than attributing discretionary intent to the CEO's execution schedule.

PSNL CEO Hall sells 100,000 shares at $11.02 (2 transactions); 236.0K shares remain post-transaction plus 680,091 in derivative holdings

Christopher M Hall, Chief Executive Officer of Personalis, Inc., executed 2 separate sales totaling 100,000 shares for $1,102,000.00 on 2026-05-28 and 2026-05-29 at $11.02 per share. The transaction was executed pursuant to a pre-arranged 10b5-1 trading plan adopted on 2025-12-17, meaning it was scheduled rather than discretionary. Hall retained 235,986 non-derivative shares post-transaction, alongside 680,091 derivative shares held through stock options, preserving a material ongoing position. The sales occurred when PSNL stock was at 52-week highs (within 0.9% of the $11.50 peak) and after a 30-day surge of 126.2%, despite the company reporting a negative full-year net income of $-30,032,000.00 and annual revenue decline of -17.7%.

Tempus AI, 10% owner, acquired 320,267 shares ($2.7M) across 12 purchases; stock now down 27.0% from 52-week high

Tempus AI, a 10% shareholder, completed 12 separate purchases totaling 320,267 shares for $2,739,181.17 between November 18 and December 22, 2025, at a blended average price of $8.55. The filing is material in scale (320.3K shares added; holdings now 13.04M shares), yet the timing raises concerns: the current price of $8.21 sits 27.0% below the 52-week high, and the stock has declined 11.7% over the past 30 days despite the acquisition activity. The insider's cross-ticker track record shows 0% win rate on 90-day holding periods, and the prior same-ticker trade at PSNL (August 2024 buy) was poorly timed, with a -15.2% return over 90 days. The company posted a $-21.7M net loss in the latest quarter and has been unprofitable over the full fiscal year, though revenue grew +15.2% annually, leaving investors to weigh near-term losses against top-line momentum.

CFO Tachibana Aaron sold 103,668 shares of PSNL at $10.78 on 2025-11-25 ($1.1M) via 10b5-1 plan

Tachibana Aaron, serving as CFO and COO, executed a sale of 103,668 shares at $10.78 on 2025-11-25 under a pre-arranged 10b5-1 trading plan adopted on 2025-08-07. The transaction reduced his holdings from 268,126 shares to 164,458 shares, a reduction of -38.7% vs pre-transaction holdings. Because this transaction is part of a scheduled 10b5-1 plan rather than discretionary trading, it reflects a pre-determined divestiture schedule set weeks in advance and does not convey directional conviction about near-term stock performance. The substantial reduction in absolute share count warrants review of the company's capital strategy and insider cash flow needs, but the scheduled nature of the trade precludes timing-based interpretation.

Tempus AI (10% owner) purchases 3.5M PSNL shares for $17.7M, raising stake to 12.72M shares (+38.0%)

Tempus AI, already a substantial 10% owner, executed a major acquisition of 3,500,000 shares at $5.07, increasing holdings by 38.0% to 12,718,800 shares total for a transaction value of $17,745,000.00. This large-scale accumulation occurs in a company with revenue of $22,580,000.00 (latest quarter) but net income of $-12,802,000.00, alongside 13.0% annual revenue growth that has not yet translated to profitability. The stock has surged 47.8% over 30 days and 265.9% over 90 days from depressed levels, recently trading at $5.69 against a 52-week high of $5.99. The transaction signal—a major holder choosing to deploy substantial capital into a money-losing but growing-revenue biotech company amid significant recent price momentum—merits close attention to Tempus AI's strategic rationale, particularly given Personalis's unprofitability and whether this positioning reflects confidence in a near-term inflection or a longer-term turnaround thesis.
