Market data cited alongside the filing noted a one-week decline in the stock of 7.7% and a market capitalization for the company of $186 million. A valuation reference from InvestingPro listed a Fair Value of $1.22 for QSI, implying a potential difference versus prevailing market levels.
Recent operating and analyst developments
Quantum-Si reported fourth-quarter results for 2025 that were mixed. The company recorded an earnings per share loss of $0.08, which was ahead of analyst expectations of a $0.12 loss. Revenue, however, missed forecasts, coming in at $451,000 versus an anticipated $761,900. In response to the quarter, Canaccord adjusted its price target for Quantum-Si shares from $1.50 to $1.00 while maintaining a Hold rating. The firm highlighted that sales of the company’s Platinum instruments were in the low-single-digit units range and that those instruments generated a gross margin around 27%.

The Form 4 documents the specifics of Dowdy’s placement of capital into Quantum-Si Class A common stock without offering commentary on motivation or future intent. The broader financial disclosure from the company for Q4 2025 and the analyst action from Canaccord provide contemporaneous context for the trade, but the filing itself contains only the transactional facts outlined above.
