MasTec is trading 12.70% up at $232.28 after the October 13 regular-session close of $206.11; supplied price context reports an after-hours move, but available reporting identifies no verified October 13 company-specific catalyst.

  • MasTec’s investor-relations news page shows an earlier September announcement, not a matching October 13 release.
  • The Nasdaq rose 0.60%, while the S&P 500 and Dow were slightly lower; the mixed market backdrop does not clearly explain the move.
