Senti Biosciences is trading 6.75% lower at $0.21 on October 20, 2026, with no confirmed company-specific announcement explaining the decline.
- Shareholders approved the merger and authorized a possible reverse split at the October 15 meeting; that earlier news does not establish a reason for this sessionβs decline.
- Pre-market biotech weakness is described as a possible factor, but conflicting sector indicators mean it cannot be confirmed as the driver.
