What Duna Services does

Duna Services LLC is an electrical utility infrastructure contractor headquartered in Wakarusa, Indiana, serving electric utility companies across the Midwest and Eastern United States. The company provides underground and overhead power distribution, transmission, substation maintenance, and emergency/storm restoration services through project-based contracts and service agreements with utility customers. It employs approximately 350 workers and operates through wholly-owned subsidiaries Arc American LLC and C.A. Advanced LLC, while holding a 49% interest in KNX Utility Services LLC, a certified women- and minority-owned utility contractor based in Rodney, Michigan.

The business model is professional-services/project-contract in nature: revenue is generated from utility infrastructure construction, maintenance, and emergency restoration work, with contract-based pricing that is not publicly disclosed. Go-to-market is direct enterprise field sales into utility buyers, targeting recurring infrastructure spend rather than one-off construction projects. The company had no AI, software, or recurring subscription revenue components; its economic engine is skilled field labor and equipment utilization against contracted scope.

In March 2026, Duna Services was acquired by Aecon Utilities Group Inc. (a subsidiary of Toronto-listed Aecon Group Inc.) from Ryker Holdings Inc. for a US$60 million base purchase price plus contingent proceeds. The transaction included the operating subsidiaries and the KNX minority stake. Post-acquisition, Duna operates as a wholly-owned subsidiary within Aecon's U.S. utilities platform, supported by Oaktree as a financial backer, and serves as a strategic Midwest/Eastern regional anchor for Aecon's stated focus on recurring utility revenue in North America.
