What Happened
Jeffrey A. Hawkins, President & CEO and a director of Quantum-Si Inc.

  • Footnotes: F1 — sales were mandatory sell-to-cover for federal/state/local tax withholding tied to RSU vesting (executive cannot alter this provision). F2/F3 — per-footnote weighted average prices and reported price ranges (sales across both dates ranged roughly from $0.9763 to $1.05); detailed per-price breakdowns available upon request.
  • Filing: Form 4 filed 2026-04-22 for report period 2026-04-20; appears to be filed within the standard two-business-day window (timely).

Context
These were sell-to-cover transactions associated with RSU vesting (tax-withholding disposals), which are routine and designed to satisfy tax obligations rather than indicate a discretionary sale. The Form 4 shows disposition code S; no options exercised or new grants were reported in the provided excerpt. Retail investors often view mandatory sell-to-cover differently than voluntary insider sales because they reflect tax mechanics rather than a direct expression of the insider’s market view.
