Senti Biosciences is trading at $0.20, up +5.15% versus the regular-session close, with no fresh company-specific announcement identified to explain the October 23 after-hours gain.

• Merger and reverse-split approvals were reported earlier, not as a new after-hours catalyst.
• A search result reports the approvals and authorization of a 1-for-20 to 1-for-50 reverse split; it does not establish that they caused the move.
• Broader market signals were mixed, with no clear market-based explanation for the increase.
