About Infrastructure & Energy Alternatives, Inc.

Infrastructure & Energy Alternatives, Inc. (IEA) was a U.S.-listed specialty infrastructure contractor that operated on the NASDAQ before being acquired by MasTec in 2022. Headquartered in Indianapolis, Indiana, and founded in 2011, the company built a national footprint across the United States by combining capabilities in renewable energy construction and heavy civil infrastructure. For investors, IEA represented a focused play on energy-transition-related construction and essential infrastructure build-out, rather than a diversified industrial conglomerate. ([cbinsights.com](https://www.cbinsights.com/company/iea?utm_source=openai)) IEA’s core business lines were centered on two complementary platforms. First, its renewables business served the wind and solar markets, where the company provided engineering, procurement, construction, and related field services for utility-scale projects. Second, its specialty civil and heavy civil operations addressed broader infrastructure needs, including environmental remediation, industrial maintenance, specialty transportation infrastructure, and site development for public and private customers. This mix gave the company exposure to both the growth in renewable generation and the ongoing demand for complex civil work tied to industrial and utility projects.

That positioning helped differentiate it from general contractors by allowing it to participate in large, specialized projects requiring field execution expertise, labor flexibility, and project management discipline. Its competitive appeal came from national scale, specialized crews, and a broad service offering spanning much of the construction lifecycle, from site preparation to installation and support activities. At the same time, the business remained exposed to normal contractor risks, including fixed-price execution pressure, commodity and labor inflation, weather disruptions, and customer concentration.

As a result, IEA no longer trades as an independent public company, which matters when reviewing historical SEC Form 4 insider filings: they relate to a business that has since been absorbed into MasTec’s Clean Energy & Infrastructure platform. For a French-speaking investor audience, the relevant takeaway is that IEA’s legacy is that of a U.S. NASDAQ-listed infrastructure contractor from the United States, headquartered in Indianapolis, with a strong focus on renewable energy, heavy civil works, and related infrastructure services.
