MasTec is trading 4.13% down now at $290 after a broad risk-off pre-market session, as weaker U.S. futures, rising oil prices and Treasury yields revive inflation concerns.

  • U.S. futures are lower: Nasdaq futures are down 1.32% and S&P 500 futures are down 0.57%.
  • MasTec completed its previously announced $650 million senior-notes offering on August 17, 2026; no reliable source directly links it to the decline.
  • Shares advanced in four of the prior five sessions, suggesting profit-taking may be amplifying macro pressure.
