What Infrastructure and Energy Alternatives does
Infrastructure and Energy Alternatives (IEA) was a publicly traded renewables and infrastructure construction company (NASDAQ: IEA) that specialized in energy and water infrastructure services, with a primary focus on clean energy projects including solar, wind, and battery storage installations, as well as civil and industrial construction supporting the energy sector. Prior to its acquisition, IEA expanded its capabilities through M&A, acquiring Saiia Construction Company and American Civil Constructors in September 2018 to broaden its infrastructure construction footprint. The company raised $148.3 million in capital in February 2021.
In 2021, IEA was acquired by MasTec (NYSE: MTZ), a Coral Gables, Florida-headquartered infrastructure construction company founded in 1943. The acquisition integrated IEA into MasTec's diversified service portfolio, which spans clean energy and infrastructure, data centers, EV charging infrastructure (MasTec EVi), pipeline infrastructure, power generation, power delivery, civil infrastructure, technology deployment (IoT last-mile fulfillment via MasTec Advanced Technologies), water and wastewater systems, communications, general building, and industrial solutions.
As a wholly-owned subsidiary of MasTec, IEA operates within an enterprise comprising nearly 22,000 skilled professionals across the parent's 11 acquisitions. The business serves utilities, developers, energy producers, and industrial customers in the United States through a direct enterprise sales motion, performing as both prime contractor and subcontractor on large-scale infrastructure builds. Pricing is project-based and contract-driven rather than disclosed at the line-item level; revenue mechanics follow industry-standard cost-plus and fixed-price contract structures typical of heavy infrastructure construction. Source data does not disclose IEA-specific financials, technology stack, or AI capabilities separate from its parent's broader portfolio.
