Winston Score History

The full picture

Quanta Services builds and repairs the infrastructure that delivers electricity, natural gas, and internet to homes and businesses. The company sends crews to construct power lines, pipelines, and fiber-optic cables across North America. Its main customers are electric utilities, pipeline operators, and telecom companies — the large businesses that own and maintain these networks.

Quanta earns money by winning contracts to complete specific construction and repair projects, so revenue depends on a steady flow of new work. It operates mostly in the United States and Canada, with some international projects, and employs roughly 50,000 skilled workers. Its large, trained workforce and deep relationships with utility customers make it difficult for smaller competitors to take its place. The biggest growth driver is the massive wave of spending utilities are planning to upgrade the electric grid and connect new renewable energy sources — though project delays or a slowdown in utility budgets remain real risks.
