Aecon strengthens North American nuclear fabrication with South Carolina facility

TORONTO, June 29, 2026 (GLOBE NEWSWIRE) -- Aecon Group Inc. (TSX: ARE) ("Aecon" or the "Company") announced today that it has expanded its footprint in the U.S. nuclear sector with the purchase of a fabrication facility in Jackson, South Carolina – strengthening its ability to support a growing roster of nuclear projects and clients across the United States. Aecon has utilized the 120,000-square-foot facility since 2015, and advancing the facility’s operations will play a key role in delivering critical fabrication and manufacturing services for nuclear refurbishment, life extension, new build, and federal projects, while also supporting conventional power and industrial projects. The facility will serve as a nuclear and ASME fabrication centre of excellence, further augmenting Aecon’s ability to deliver complex components to the highest quality standards and demonstrating a long-term investment in U.S. nuclear supply chain capacity. “This investment builds on Aecon’s established, integrated nuclear fabrication network across North America,” said Aaron Johnson, Senior Vice President, Aecon Nuclear. “The Jackson facility strengthens Aecon’s ability to provide localized fabrication capacity for U.S. customers, while drawing on decades of experience and technical excellence.

It enhances Aecon’s integrated, self-perform solutions – combining engineering, fabrication, modularization, and construction to meet the evolving needs of commercial and federal nuclear clients.” Aecon’s Fabrication Facility and Welding Centre of Excellence in Cambridge, Ontario, serve as cornerstones of its capabilities, supporting some of the largest nuclear refurbishment and new build projects in North America. They provide advanced welding, machining, modularization, and specialty fabrication services, enabling Aecon to self-perform and maintain control over quality, safety, and schedule across the full project lifecycle. Together, Aecon’s nuclear fabrication facilities create a scalable platform that supports both large-scale refurbishment programs and next-generation nuclear projects across North America and beyond.

This includes the first grid-scale Small Modular Reactor (SMR) project in the G7 currently under construction in Ontario, where Aecon is leveraging its fabrication expertise, modular construction approach, and specialized workforce to help deliver this first-of-a-kind project. The facilities hold certification stamps for nuclear quality management systems compliant with CSA standards in Canada and ASME (N, NPT, NS, and NA stamps), as well as programmatic compliance with U.S. federal regulation 10 CFR 50 Appendix B. As demand continues to grow, Aecon’s 4,000-strong nuclear workforce and expanding fabrication footprint underscore its long-term commitment to the U.S. market – positioning the company to play a key role in strengthening domestic supply chains and supporting energy security across North America.
