Quantum-Si (QSI) Director Kevin Rakin Receives 251,185-Share Award

What Happened
Kevin Rakin, a director of Quantum-Si Inc. (QSI), was reported to have acquired 251,185 derivative shares on 2026-05-18 at a $0.00 price (no cash paid). The filing shows this was an award/acquisition (derivative), not an open-market purchase or sale, and the award carries vesting terms rather than an immediate cash sale.

Key Details

  • Transaction date: 2026-05-18; Filing date: 2026-05-20 (appears timely).
  • Instrument and amount: 251,185 shares (derivative/award) acquired at $0.00; reported value $0.
  • Shares owned after transaction: The filing indicates Mr. Rakin may be deemed to share voting and investment discretion over 1,200,000 Class A shares held by affiliated HighCape entities (24,527 + 1,175,473) — adding the 251,185 award would bring related holdings to 1,451,185 shares.
  • Footnotes of note:
    • F1: These shares were distributed in kind by HighCape Partners QSI II Invest, L.P. to its limited partners pro rata for no consideration.
    • F2: Mr. Rakin is the managing member of entities that control the HighCape funds holding 1,200,000 shares and therefore may share voting/investment discretion.
    • F3: The shares underlying this option/award vest on the date of the issuer’s next regular annual stockholders meeting, subject to continued service.
  • Timeliness: Filed two days after the reported transaction date; not marked as late in the filing.

Context
This is a derivative award distributed in kind by a HighCape fund to its limited partners and tied to vesting at the company’s next annual meeting. It was not a public-market purchase or sale and did not generate cash proceeds. Because the shares originate from a fund distribution and Mr. Rakin is connected to the fund’s GP entities, the filing reflects both the distribution and the GP-related beneficial ownership disclosures rather than a typical personal open-market trade.
