Key risks (from latest filing)

["Heavy dependence on U.S. Department of Energy funding, appropriations, and procurement processes, which are subject to timing delays and policy changes beyond the company's control","Current unprofitability with -30% net margin; company incurring fixed operating costs and making capital investments in anticipation of future waste treatment volumes that may not materialize as expected","Backlog conversion risk: Treatment Segment backlog does not guarantee immediate revenue as processing timing varies based on waste complexity, customer requirements, and operational considerations"]
