CENTRAL PLATEAU CLEANUP COMPANY, LLC: $1.0B Department of Energy Contract

The Department of Energy issued Task Order 7 under the Hanford Central Plateau Cleanup Contract to Central Plateau Cleanup Company, LLC – a wholly owned subsidiary of Amentum Holdings. The award amount is $1.0 billion over a three-year period (FY2025-2027), though the initial binding not-to-exceed value is $98 million pending definitization. This contract covers base operations and end-state cleanup at the Hanford nuclear site, one of the world's largest environmental remediation projects.

The publicly traded parent company is Amentum Holdings ($AMTM), which generated $7.9B revenue and a net loss of $314M in FY2025. The annualized revenue from this contract (≈$333M) represents ~4.2% of Amentum's top line. While not transformative given Amentum's scale, the contract provides a multi-year revenue stream in a high-barrier segment (nuclear waste cleanup) and improves visibility into future earnings. The company's negative net margin (-3.99%) means every dollar of incremental revenue with decent margins directly improves profitability.

There are no specific related bills in the provided data that directly appropriate or authorize this contract. However, the Hanford cleanup is funded through annual Energy & Water Development appropriations and the Defense Environmental Cleanup account. Broader legislation like the National Defense Authorization Act (NDAA) authorizes DOE environmental management activities, but no specific bill signal ties directly to this task order.

Subcontractor opportunities likely flow to specialized nuclear waste treatment firms. Potential publicly traded beneficiaries include Clean Harbors ($CLH) for waste transportation and disposal, Perma-Fix Environmental Services ($PESI) for treatment of mixed low-level waste, and BWX Technologies ($BWXT) for nuclear materials handling. These companies have seen consistent demand from DOE cleanup programs.

Historically, large DOE cleanup contracts – such as the Hanford Tank Waste Treatment and Immobilization Plant contracts – have provided years of stable revenue for prime contractors and have been viewed positively by investors. Amentum's predecessors (URS, AECOM) have successfully executed similar long-term contracts, and the stock tends to rise on award announcements due to backlog growth and earnings visibility. The structural pattern favors companies with exclusive or near-exclusive positions at large DOE sites.
