MasTec Expands Infrastructure Platform with Acquisition of The Superior Group to Strengthen Data Center and Mission-Critical Capabilities
MasTec, Inc., one of North America’s leading infrastructure construction companies, has announced that it has entered into a definitive agreement to acquire Electrical Specialists, Inc., doing business as The Superior Group (Superior), a nationally recognized full-service electrical contractor specializing in mission-critical infrastructure projects. The acquisition represents a significant step in MasTec’s long-term growth strategy, expanding its capabilities in the rapidly growing data center, power, and critical infrastructure markets while strengthening its position as a comprehensive infrastructure solutions provider.
Founded in 1925 and headquartered in Columbus, Ohio, Superior has built a century-long reputation for delivering complex electrical construction projects across the United States. Since the mid-1980s, the company has been guided by the Stewart family after Greg Stewart acquired an ownership interest in the business. Under the leadership of Chairman and Chief Executive Officer Bryan Stewart, Superior has evolved into one of the nation’s largest and most respected electrical contractors, employing approximately 3,000 skilled professionals and serving a broad range of industries.
Today, Superior is recognized as a leading contractor in the construction of data center infrastructure, one of the fastest-growing segments of the U.S. construction market. In addition to supporting hyperscale data center development, the company provides electrical contracting services for healthcare facilities, industrial complexes, entertainment venues, and other mission-critical environments where reliability, precision, and technical expertise are essential.
The company delivers a comprehensive portfolio of services that spans every phase of a project lifecycle. Its capabilities include engineering and design, preconstruction planning, project management, electrical construction, integrated building systems, prefabrication, modular manufacturing, commissioning, and long-term maintenance, repair, and retrofit services. This end-to-end approach has enabled Superior to establish long-term relationships with many of the country’s largest institutional and commercial customers.
For MasTec, the acquisition aligns closely with its strategic objective of building a fully integrated infrastructure platform capable of meeting the rapidly increasing demand for modern energy, communications, and digital infrastructure.
Demand for large-scale infrastructure investment continues to accelerate across North America, fueled by expanding cloud computing, artificial intelligence, advanced manufacturing, renewable energy, electrification, and the modernization of power grids. Massive investments in hyperscale data centers and mission-critical facilities have created significant opportunities for companies capable of delivering specialized engineering and construction services at scale.
By bringing Superior into its portfolio, MasTec significantly enhances its ability to support these complex projects from initial power generation through final electrical installation and ongoing maintenance.
The combination creates a broader suite of integrated services covering power generation, transmission infrastructure, substations, civil construction, communications systems, inside-the-fence electrical work, and long-term operational support.
Company executives believe this expanded service offering will allow MasTec to better serve customers seeking comprehensive infrastructure solutions delivered through a single experienced partner.
Superior has demonstrated consistent financial strength in recent years.
During the four-year period ending December 31, 2025, the company achieved double-digit compounded annual growth in both revenue and net income. This performance has been driven by increasing customer demand for data center and mission-critical infrastructure, a strong portfolio of repeat clients, and successful execution of large, technically sophisticated projects across multiple industries.
Looking ahead, Superior is projected to generate between $1.6 billion and $1.7 billion in revenue during 2026, while expected Adjusted EBITDA is forecast to range from approximately $225 million to $250 million.
Following completion of the transaction, Superior will operate as a new business unit within MasTec, with its financial results being reported as part of the company’s Power Delivery segment.
An important aspect of the acquisition is the continuity of Superior’s leadership.
Bryan Stewart and the existing executive management team will remain in place after the transaction closes. Their continued leadership is expected to provide operational stability while preserving the entrepreneurial culture, technical expertise, and customer relationships that have contributed to Superior’s long-standing success.
MasTec views Superior’s experienced management team as one of the company’s greatest strengths. Their decades of industry knowledge and proven ability to successfully manage large, complex infrastructure projects are expected to complement MasTec’s national footprint and diversified capabilities.
Jose Mas, Chief Executive Officer of MasTec, welcomed Superior and its employees to the organization, describing the acquisition as an important milestone in the company’s continued expansion.
According to Mas, Superior has established one of the strongest electrical infrastructure platforms in the United States, consistently demonstrating the ability to mobilize skilled labor, manage highly complex projects, and deliver reliable results for customers operating mission-critical facilities.
He noted that the acquisition significantly enhances MasTec’s ability to participate in one of today’s most attractive infrastructure markets: the ongoing nationwide expansion of data centers, electric power systems, and other critical infrastructure supporting the digital economy.
Mas explained that combining Superior’s electrical construction expertise with MasTec’s existing strengths in power generation, transmission, substations, communications infrastructure, and civil construction creates a comprehensive service platform capable of supporting customers across every stage of infrastructure development.
He also emphasized that Superior’s experienced workforce and strong safety culture complement MasTec’s commitment to operational excellence.
The integration of both organizations is expected to create meaningful value not only for customers but also for employees and shareholders by expanding market opportunities and strengthening long-term competitive positioning.
Bryan Stewart also expressed enthusiasm about joining MasTec as Superior begins its second century of operation.
He said the transaction represents an exciting opportunity to combine Superior’s extensive experience in building mission-critical electrical infrastructure with MasTec’s leadership across the energy, communications, and power sectors.
According to Stewart, the combined organization will be exceptionally well positioned to support the next generation of infrastructure investment occurring throughout the United States.
He highlighted the unprecedented growth taking place in digital infrastructure, describing it as a once-in-a-generation opportunity to help build the foundation supporting America’s increasingly connected economy.
Industry analysts have identified data centers as one of the fastest-growing infrastructure sectors globally.
The rapid expansion of artificial intelligence applications, cloud computing platforms, digital services, and high-performance computing has significantly increased demand for large-scale facilities requiring advanced electrical systems, redundant power supplies, and sophisticated engineering solutions.
At the same time, broader investments in grid modernization, renewable energy integration, and industrial electrification continue to create substantial opportunities for specialized infrastructure contractors.
MasTec believes the acquisition positions the company to capitalize on these long-term growth trends while expanding its presence in markets expected to experience sustained investment for many years.
The transaction also reinforces MasTec’s strategy of combining complementary infrastructure businesses that enhance its technical capabilities and geographic reach.
By integrating Superior’s electrical expertise with its existing operations, MasTec expects to offer customers broader self-perform capabilities, greater project execution capacity, and more comprehensive infrastructure solutions across multiple industries.
As infrastructure investment continues to accelerate nationwide, the combined organization aims to play a leading role in delivering the advanced electrical, energy, communications, and mission-critical systems required to support the future of digital connectivity, economic growth, and national infrastructure development.
