HOUSTON – Oct. 30, 2025 – Quanta Services, Inc. (NYSE: PWR) today announced the expansion of its total solutions platform, which builds upon Quanta’s world-class craft-skill labor capabilities and decades of experience constructing power generation through its industry-leading renewable energy and battery energy storage solutions for utility scale power consumers, as well as other forms of generation. This platform is focused on providing a fully integrated solution to high-quality customers for their power generation development strategies and is designed to maximize collaboration and efficiency to provide clients with industry-leading energy infrastructure expertise, high labor certainty and a cost-effective contracting approach, that is expected to mitigate execution risk and support customer affordability objectives. This total solutions platform expansion leverages Quanta’s world-class capabilities to address growing power generation and infrastructure needs from rapidly increasing demand for electricity driven by data centers, manufacturing and reshoring, industrialization, electrification and power grid expansion.

Quanta has expanded its solutions platform by investing in personnel with extensive engineering, procurement and construction (EPC) experience designing and building gas power generation and other heavy industrial manufacturing plants and leveraging Quanta’s operating companies to provide craft-skilled, self-perform capabilities and industry partnerships, where appropriate.

Duke Austin, Quanta’s President and Chief Executive Officer, commented, “Many of Quanta’s existing customers are experiencing significant increases in power demand, are expanding their power generation portfolios and are coming to Quanta for solutions due to our longstanding, collaborative relationships with them. Our total solutions power generation platform is designed to deliver an integrated approach to power generation and related infrastructure that leverages Quanta’s capabilities for a differentiated solution. Quanta will continue to invest in craft training and support our customers through this market expansion, as the convergence of the utility, technology, large load and generation industries intensifies.”

As a demonstration of this platform’s strength and scalability, NiSource, Inc. has engaged Quanta for the design, procurement and construction execution of generation and infrastructure resources capable of producing approximately 3 gigawatts of power for a large load customer.

“NiSource is committed to advancing transformative growth while ensuring that customer affordability remains at the heart of our strategy,” said Lloyd Yates, NiSource’s President and Chief Executive Officer. “Through this collaboration with Quanta and Zachry, we are expanding generation and grid infrastructure in a way that supports economic development and innovation while protecting customers from the costs of infrastructure investment. We are excited to partner with Quanta and Zachry to meet the evolving energy needs of our customers and communities.”

Abbey Roy, President of Quanta’s Power Generation Solutions, said, “NiSource has been a valued partner of Quanta Services, and we are proud to collaborate with them and Zachry on this project. By leveraging our integrated solution capabilities, craft-skilled workforce and disciplined execution, Quanta provides customers with greater certainty in delivering complex projects. This project highlights the strength of our total solutions platform—spanning power generation, battery energy storage, transmission, substation and underground infrastructure—and builds on our relationship with NiSource and deep roots in Indiana, where we have created thousands of skilled jobs that support families and communities. Together, with Zachry, we are advancing critical energy infrastructure that will power the economy and strengthen the grid for decades to come.”

The joint venture between Quanta and Zachry for the design, construction and delivery of the combined cycle gas turbines (CCGTs) is intended to maximize collaboration and efficiency to provide NiSource with industry-leading gas power generation expertise, high labor certainty and a cost-effective contracting approach that is expected to mitigate execution risk, by leveraging the respective strengths of Quanta and Zachry. Quanta will leverage multiple operating companies to provide field-

level leadership, expertise and management of the craft-workforce across civil, structural, mechanical, electrical, controls and other infrastructure. Zachry will leverage its extensive gas power plant experience, which spans more than five decades and includes the design and construction of over 100 facilities comprising more than 60,000 megawatts, to lead engineering, project management and commissioning and start-up for the CCGTs. Quanta has a 50% ownership interest in the joint venture.

“We are proud to bring our decades of experience in designing large-scale gas power facilities to this important project,” said John Zachry, Chairman and Chief Executive Officer of Zachry Group. “Zachry has delivered over 100 gas-fired power plants across the country, and that proven track record gives us the technical depth and execution certainty required for projects of this scale. Working alongside Quanta, we look forward to safely and efficiently delivering infrastructure that provides reliable power for demand growth and supports long-term grid stability.”

The scope and estimation phase of the project has begun, and the execution phase is expected to begin in 2026 after receipt of certain regulatory approvals. The delivery of power generation capacity is expected to occur in phases through the course of the project, with full power availability and project completion expected by 2032. Quanta expects to recognize the financial contribution from the joint venture through proportionate consolidation. The remaining performance obligations and backlog for this project are expected to be primarily reflected in the Electric Infrastructure Solutions segment and recognized over multiple quarters.
