Jeffrey Alan Hawkins, the president and chief executive officer of Quantum-Si Inc (NASDAQ: QSI), reported the sale of 23,777 Class A common shares in two transactions on March 20 and March 23, 2026, according to a Form 4 filed with the Securities and Exchange Commission.
The March 20 transaction consisted of 11,628 shares sold at a weighted average price of $0.8483 per share, with trade prices in the lot ranging from $0.8314 to $0.8718. That tranche generated $9,864 in proceeds. On March 23, Hawkins sold 12,149 shares at a weighted average of $0.8266, with individual prices between $0.7973 and $0.8525, producing $10,042. Combined, the two transactions totaled $19,906.
The Form 4 filing attributes the sales to the statutory sell-to-cover mechanism used to satisfy federal, state and local withholding taxes arising from the vesting of previously granted restricted stock units. The filing notes that the mandatory sell-to-cover provision is set at the grant date of the related restricted stock unit award and cannot be altered by the individual.
After these transfers, Hawkins is shown as directly holding 3,859,847 shares of Quantum-Si common stock.
Market context provided in the filing and accompanying market data indicate QSI shares are trading close to a 52-week low of $0.79 and are down 22.6% year-to-date. An InvestingPro valuation cited alongside the filing estimates a Fair Value of $1.13 per share, implying a valuation gap to the prevailing market price at the time of the transactions.
Separately, Quantum-Si disclosed mixed financial results for the fourth quarter of fiscal 2025. The company reported earnings per share of negative $0.08, which exceeded consensus analyst expectations of negative $0.12. Revenue, however, missed projections: Quantum-Si recorded $451,000 in quarterly revenue versus a forecast of $761,900.
In response to the weaker top-line performance, Canaccord reduced its price target for Quantum-Si from $1.50 to $1.00 while maintaining a Hold rating. In its commentary, the firm referenced the company’s weak fourth-quarter results and noted that Quantum-Si reported low-single-digit sales of its Platinum instruments during the quarter, with a gross margin of roughly 27%.
These financial details and the insider filing together outline the recent activity at Quantum-Si: a CEO sell-to-cover for tax obligations tied to vested RSUs alongside a quarter that beat on EPS but fell short on revenue, and an analyst reaction trimming valuation expectations.
