QSI Quantum-Si Inc Insider Trading

Director Kummeth Charles R. buys 500,000 QSI shares at $0.92; holdings now 855,000 (+140.8%)

Kummeth purchased 500,000 shares at $0.92 on 2026-03-05, more than doubling his stake from 355,000 to 855,000 shares. His prior two purchases at QSI were both well-timed at the 90-day mark, with returns of +3.9% and +4.6% respectively, suggesting pattern recognition in his entry decisions. However, the current context is challenging: QSI is trading at $0.93 (the purchase price), down 64.6% from its 52-week high of $2.63, down 12.7% over 30 days, and down 34.5% over 90 days. Fundamentals show the company unprofitable with net income of $-35.7M and declining revenue (-20.3% year-over-year), with latest quarterly revenue at only $552.0K. The director's substantial accumulation at distressed valuations warrants attention to whether this reflects conviction in a turnaround or simply availability to purchase at depressed price levels while broader company metrics deteriorate.

Director Dowdy Paula bought 109,890 shares of QSI at $0.95 while stock down 64.6% from 52-week high; company posted $-35.7M net loss.

Dowdy Paula, a Director, purchased 109,890 shares at $0.95, expanding her holdings by 69.0% from 159,217 to 269,107 shares. The transaction occurred while Quantum-Si's stock trades at $0.93, down 64.6% from its 52-week high of $2.63 and down 34.5% over the past 90 days, suggesting considerable loss of shareholder value. The company's fundamentals are severely strained: it posted a net loss of $-35.7M in its most recent full fiscal year, generated only $552,000.00 in quarterly revenue, and contracted 20.3% year-over-year in annual revenue. A substantial insider equity purchase during a period of acute financial distress and severe stock depreciation merits investor scrutiny of the underlying catalysts and company outlook.

Director Jonathan M Rothberg sells 3,506,267 shares (73.7% of holdings) for $11.7M at blended avg $3.34

Jonathan M Rothberg executed 8 separate sales on 2024-12-27 totaling 3,506,267 shares for $11,716,734.62, reducing his holdings from 4,756,267 to 1,250,000 shares. The transaction occurred at a blended average price of $3.34, notably above the current price of $2.70 (19% higher) and near the company's 52-week high of $3.60. This is a substantial reduction in direct ownership stake by a director at a company that posted quarterly revenue of $787,000 and full-year net income of $-25,313,000, indicating the business is unprofitable and losing significant cash. The magnitude of the reduction (73.7% of pre-transaction holdings) combined with the company's deteriorating financial condition and the stock's recent decline to $2.70 suggests a material shift in the director's exposure to QSI at an inflection point in the company's market performance.

His prior buy at this same ticker on 2024-03-14 saw 30-day and 90-day returns of -4.0% and -13.6% respectively, with a 0.00% 90-day win rate across his open-market history. A cluster of 3 other insiders also purchased within the past 14 days, indicating coordinated insider buying activity at depressed valuations, though the pattern of poor timing on prior purchases and the company's ongoing unprofitability warrant caution about the strength of this signal.

General Counsel buys 25,000 QSI shares at $0.86; stock down -62.2% from 52-week high, company unprofitable with $-23.1M net loss.

LaPointe Christian, General Counsel & Corp. Secretary, purchased 25,000 shares at $0.86 on 2024-08-09, increasing his stake to 571.7K shares.

Fundamentally, the company is unprofitable with a $-23.1M net loss in its most recent full fiscal year and quarterly revenue of only $622.0K, indicating severe operational challenges. Notably, this buy occurred within a 14-day cluster in which 3 other insiders also purchased shares, yet LaPointe's own prior buy at QSI on 2024-03-15 demonstrated poor timing outcomes (90d return: -17.2%), and his cross-ticker track record shows 0 of 1 prior buys were well-timed at the 90-day mark with an average 90d return of -17.2%.

The company reported revenue of $622,000.00 in its latest quarter and a net loss of $-23,099,000.00, underscoring significant unprofitability. Notably, 3 other insiders also bought within the past 14 days, indicating a cluster buy pattern. Investors should note that the stock has declined 62.2% from its 52-week high and fallen 51.1% over 90 days, suggesting the market has priced in material headwinds despite the insider activity and clustered buying.

CFO Keyes bought 50,000 QSI shares at $0.87; stock down 62.2% from 52-week high, company unprofitable with -$23.1M net income.

Keyes Jeffry R., CFO, purchased 50,000 shares at $0.87 on 2024-08-09, increasing his holdings by 12.6% to 446,820 shares. The purchase occurs in a depressed price environment: QSI trades at $0.91, down 62.2% from its 52-week high of $2.41 and 51.1% lower over the past 90 days. Fundamentally, the company is severely distressed, reporting a net loss of $-23.1M against quarterly revenue of $622.0K. Keyes' own historical buy pattern at this ticker is not encouraging: his prior March 2024 purchase showed a 90-day return of -6.8%, and his cross-ticker track record shows a 0.00% 90-day win rate. The purchase is part of a broader insider cluster, with 3 other insiders also buying within the past 14 days. While cluster activity can reflect management conviction, it also warrants scrutiny given the company's severe financial deterioration and the CFO's poor prior execution timing in this exact position.
