MasTec’s stock closed at $385.00 on May 19, 2026, driven by strong demand for AI-capable data center infrastructure projects.
MasTec Inc. (NYSE:MTZ) benefited from increased investment in AI-capable data centers during Q1 2026, closing at $385.00 per share on May 19. The company’s focus on infrastructure engineering and construction for communications and energy sectors positioned it favorably amid rising demand for advanced data infrastructure.
The broader US stock market saw volatility in early 2026, with growth stocks underperforming as investors shifted to defensive strategies.
