SAB Biotherapeutics is trading at $2.91, up 8.76% in pre-market; no clear reported catalyst for the rise was found.

  • The previous close was $2.68; supplied market context is mixed and does not point to a clear broad-market explanation.
  • SAB Biotherapeutics announced FDA Fast Track designation for SAB-142 on October 13, but available evidence does not establish that it explains the October 14 move.
  • The move is notable after two consecutive declines.
