First Tracks (TRAX) 10% Owner AnaptysBio Distributes 100 Shares

What Happened
AnaptysBio, Inc. — reported as a 10% holder of First Tracks Biotherapeutics, Inc. (TRAX) — recorded a disposition of 100 shares on April 20, 2026. The transaction was not a market sale but a distribution: AnaptysBio distributed its 100 shares (which constituted all issued and outstanding First Tracks common stock) to AnaptysBio common stockholders in a spin-off. No per-share price or sale proceeds are reported (N/A).

Key Details

  • Transaction date: April 20, 2026 (Spin-off occurred before market open).
  • Filing date: Form 4 filed April 22, 2026 (timely; within the typical two-business-day window).
  • Shares involved: 100 shares disposed (represented all issued and outstanding First Tracks shares at time of distribution).
  • Price/value: Not applicable (distribution); reported as N/A.
  • Footnotes: F1–F3 explain that AnaptysBio owned the 100 shares and distributed them to its shareholders in the Spin-Off with record date April 20, 2026.
  • Insider type: Institutional 10% owner (AnaptysBio), not an individual executive — this is a corporate distribution, not a personal trade.

Context
This filing reflects a corporate spin-off distribution, not a purchase or a market sale, so it doesn't signal executive buying or selling intent. Because AnaptysBio previously held all outstanding shares and distributed them to its shareholders, AnaptysBio no longer holds those First Tracks shares after the distribution.
