What Happened
Michelle Gilson, Chief Financial Officer of Arcellx, transferred (gifted) 5,000 shares of Arcellx common stock on March 17, 2026. The reported disposition price is $0.00 (a gift), so the transaction value is $0. This was recorded on a Form 4 filed March 19, 2026.

Key Details

• Transaction date: March 17, 2026; Form 4 filed: March 19, 2026 (within the typical two-business-day filing window).
• Transaction code: G (Gift). Price per share reported: $0.00; total reported value: $0.
• Shares disposed: 5,000. Shares owned after the transaction: not specified in the provided filing.
• Footnote (F1): The 5,000 shares were transferred for no consideration to a family charitable foundation of which Gilson serves as President; she retains voting and investment power over securities owned by the foundation.

Context
Gifts are reported as disposals but do not necessarily signal the insider's view of the company's prospects. Note that because Gilson remains President of the recipient foundation and retains voting and investment power, she may still exercise influence over those shares even though they were transferred. This is a non-cash, non-market transaction and should be interpreted accordingly.
