Senti Biosciences is trading at $0.20, down 5.49% after hours; no clear company-specific catalyst was identified.

  • October 28’s regular-session close was $0.22, up 15.21%, before the reversal.
  • The company disclosed a director’s resignation and set October 30 as the record date for its previously announced CVR distribution; both were reported before the move and do not clearly explain its direction.
  • Nasdaq Composite fell 2.14%; broader indexes were mixed, so market context alone does not establish the cause.
