MasTec (MTZ) Stock Analysis & Winston Score
MasTec is a construction and engineering company that builds the infrastructure behind everyday services — things like power lines, pipelines, cell towers, and broadband networks. Its main customers are large utility companies, telecom providers like AT&T and Comcast, and energy companies. MasTec is one of the largest specialty contractors in the United States. The company makes money by winning contracts to design and build infrastructure projects, then charging for labor, equipment, and materials. It operates primarily across the U.S., with some work in Canada and Latin America, and generates roughly $12–13 billion in annual revenue. Its competitive edge comes from its scale, skilled workforce, and long-term relationships with major utility and telecom clients. The key growth driver is the massive wave of spending on clean energy infrastructure — wind, solar, and grid upgrades — but that same exposure to large, complex projects creates risk if costs run over budget or contracts are delayed.
