Winston Score History

The full picture

Perma-Fix Environmental Services is a company that cleans up and safely disposes of radioactive and hazardous waste. Its main customers are the U.S. federal government, including the Department of Energy and the Department of Defense, along with nuclear power plants and other industrial facilities. It is one of the few private companies in the United States licensed to treat and process mixed radioactive and hazardous waste.

The company earns money by charging customers fees to collect, treat, store, and dispose of dangerous waste materials. Perma-Fix operates several licensed treatment facilities across the United States and also has a small services segment that handles environmental cleanup projects at contaminated sites. Its specialized licenses and regulatory approvals create a barrier that makes it hard for new competitors to enter the market. However, the company currently operates at a loss, and its financial performance depends heavily on the timing and size of government contracts, which can be unpredictable.

Cash watch
