MasTec is trading 4.06% down at $225.67 after falling from the September 2 regular-session close of $235.21, with no clear company-specific catalyst identified.
- The latest investor-relations release was the August 6 pricing of $650 million senior notes; the latest earnings release came July 30, making both stale explanations.
- The broader market was modestly higher, so the decline appears stock-specific but unexplained.
