MasTec shares plunge 17.7% on disappointing Q2 earnings forecast despite $4.37B revenue beat

MasTec shares fell 17.7% after the infrastructure construction company reported mixed second-quarter 2026 results. Revenue of $4.37 billion rose 23.4% year-over-year and slightly beat analyst expectations. However, adjusted earnings of $2.22 per share missed the Wall Street consensus of $2.23. The company raised its full-year adjusted EPS guidance to a midpoint of $9.30, but this remained below analyst projections. Investors focused on the earnings miss and disappointing outlook rather than the revenue beat, triggering a sharp sell-off. MasTec shares are up 17.1% year-to-date but remain 39.1% below their 52-week high of $437.51 from May 2026.
