Quanta Services is trading 7.55% up at $668.75 after no new August 28, 2026 company-specific catalyst was identified.

  • The latest major catalyst remains the July 30, 2026 earnings beat and raised outlook, including $9.56 billion revenue, $4.24 adjusted EPS, and a record $53 billion backlog.
  • That announcement is not new, and the broader market is mixed, so it does not clearly explain this outsized move.
