SOUTHERN OHIO CLEANUP COMPANY LLC: $400M Department of Energy Contract

The Department of Energy awarded a $400M delivery order to Southern Ohio Cleanup Company LLC, a subsidiary of Amentum Holdings ($AMTM), for decontamination and decommissioning at the Portsmouth site. The contract spans fiscal years 2026 through 2031, providing a multi-year revenue stream for the prime contractor. This task order falls under an existing contract vehicle and represents a significant commitment to environmental remediation at a key DOE site.

Amentum Holdings, the publicly traded parent, reported FY2025 revenue of $7.9B and a net loss of $314M. The $400M award translates to roughly $66.7M per year, or 0.84% of annual revenue. While not transformative, it adds meaningful backlog to AMTM's core environmental cleanup segment, which is critical for a company currently operating at a net loss. The contract reinforces AMTM's position as a leading DOE cleanup contractor and provides revenue visibility that may support margin improvement over the contract period.

No direct legislative connection was identified from the provided bill signals. However, the contract is consistent with ongoing DOE Environmental Management funding, which is authorized through annual appropriations and broader energy legislation. The absence of a specific authorization bill does not diminish the contract's impact, as it is a task order under an existing program.

Subcontractors likely include engineering and environmental firms with nuclear expertise. Jacobs and Tetra Tech are well-positioned to provide support services. Jacobs' nuclear division frequently partners on DOE D&D projects, while Tetra Tech has a strong environmental consulting practice. These companies may see incremental revenue, though the amounts are uncertain and likely small relative to their total revenues.

Historically, DOE cleanup contracts provide stable, long-term revenue for contractors like AMTM. Similar awards have contributed to sustained backlog growth and operational stability. For AMTM, this contract adds to a portfolio of DOE work that forms the backbone of its business. Investors should watch for additional task orders and the company's ability to execute profitably on this award.
