Aecon expanded its footprint in the U.S. nuclear industry with the acquisition of a fabrication plant in South Carolina, bolstering its ability to support growing demand for nuclear-power projects across the country.

The Canadian construction company said the 120,000-square-foot facility in Jackson would strengthen its ability to provide localized fabrication capacity for U.S. customers.

Aecon has used the site since 2015, and said advancing the facility's operations would play a key role in delivering manufacturing services for nuclear refurbishment, life extension, new build and federal projects. The facility also would support conventional power and industrial projects, it said.

The purchase price wasn't disclosed.

Aecon said that as demand continues to grow, its 4,000-strong nuclear workforce and expanding fabrication footprint underscore a long-term commitment to the U.S. and position the company to play a key role in strengthening domestic supply chains and energy security across North America.

Aecon's shares were up 2% in afternoon trading Monday, at 44.87 Canadian dollars (US$31.61), outperforming a dip in the broader Toronto stock market.
