Quantum-Si Incorporated (QSI) Form 4 – insider activity snapshot
Chief Product Officer John S. Vieceli reported one transaction dated 06/23/2025. He disposed of 21,923 Class A common shares at a weighted-average price of $1.6139 through the company’s mandatory “sell-to-cover” program that automatically sells shares to satisfy federal, state and local tax withholding triggered by the vesting of previously granted restricted stock units. The officer had no discretion over the timing or volume of the sale, which generated roughly $35,000 in gross proceeds based on the reported average price range of $1.55-$1.68.
After the sale, Vieceli maintains direct ownership of 842,586 shares, retaining more than 97 % of his pre-transaction stake. No derivative securities were acquired or disposed of, and no additional open-market activity is disclosed. Because the disposition was administrative and pre-arranged at grant, it is generally viewed as neutral from a sentiment standpoint, though investors often track any insider sales for potential signals of executive confidence.
Christian LaPointe, General Counsel and Corporate Secretary of Quantum-Si, reported a transaction involving the company's Class A Common Stock on June 23, 2025. The insider sold 11,946 shares at a weighted average price of $1.6139 per share, with individual sale prices ranging from $1.55 to $1.68.
This sale was executed through a mandatory sell-to-cover provision to satisfy tax withholding obligations related to the vesting of restricted stock units (RSUs). The transaction was automatic and non-discretionary, as LaPointe had no control over this mandatory provision established at the RSU grant date.
Following the transaction, LaPointe continues to hold 971,534 shares directly. This Form 4 filing demonstrates standard tax-related share sales common during RSU vesting events rather than discretionary trading activity by the insider.
