QUANTA SERVICES INC

Quanta Services, Inc. (together with its subsidiaries, "Quanta," "we," "us" or "our") is a leading provider of comprehensive infrastructure solutions for the electric and gas utility, power generation, large load center, manufacturing, communications, pipeline and energy industries in the United States, Canada, Australia and select other international markets. We provide design, engineering, procurement, construction, upgrade and repair and maintenance services for infrastructure within each of these industries, including electric power transmission and distribution networks; substation facilities; wind, solar and gas power generation and transmission and battery storage facilities; low voltage electrical, mechanical, plumbing and process infrastructure for large load centers, such as data center, advanced manufacturing, healthcare, pharmaceutical and industrial facilities; communications and cable multi-system operator networks; gas utility systems; pipeline transmission systems and facilities; and downstream industrial facilities. Our operations are decentralized and labor-intensive, and we rely on craft skilled labor personnel and experienced operators to successfully manage our day-to-day business. We also have an experienced management team, both at the executive and regional levels and within our subsidiaries, which we refer to as operating companies. We operate a fleet of owned and leased trucks and trailers, support vehicles and specialty construction equipment, as well as various proprietary technologies that enhance our service offerings. We have a large and diverse customer base, including many of the leading companies in the utility, renewable energy, hyperscaler, technology, communications, industrial and energy delivery markets.

The performance of our business generally depends on our ability to obtain contracts with customers and to effectively deliver the services provided under those contracts. Our services are typically provided pursuant to master service agreements (MSAs), repair and maintenance contracts and fixed price and non-fixed price construction and engineering contracts. We offer comprehensive and diverse solutions on a broad geographic scale and have a solid base of long-standing customer relationships in each of the industries we serve. We believe our reputation for safety leadership, responsiveness and performance, geographic reach, comprehensive service offerings and financial strength have resulted in strong relationships with numerous customers, and we endeavor to develop and maintain strategic alliances and preferred service provider status with our customers.

We believe that our business strategies, along with our safety culture and financial resources, differentiate us from our competition and position us to benefit from future programmatic and capital spending by our customers. Our strategies include delivering and continuing to expand our portfolio of infrastructure solutions to existing and potential customers, developing our technological and training capabilities, remaining committed to the safety of our employees, and maintaining an entrepreneurial culture throughout our organization. We believe executing on these strategies places us in the position to be a solutions provider to our customers and capitalize on opportunities and trends in the industries we serve and expand our operations to select new markets.

During the three months ended March 31, 2025, Quanta’s Chief Executive Officer reevaluated how performance of the business is assessed and how resources are allocated, which resulted in a change in the reporting of management’s internal financial information. As a result, beginning with the three months ended March 31, 2025, Quanta began reporting the results of its two operating segments, which are also its two reportable segments: (1) Electric Infrastructure Solutions (Electric) and (2) Underground Utility and Infrastructure Solutions (Underground and Infrastructure). The Electric segment consists of the historical Electric Power Infrastructure Solutions and the Renewable Energy Infrastructure Solutions segments. In conjunction with this change, certain prior period amounts have been recast to conform to this new segment reporting structure.
