Key risks (from latest filing)
["Significant dependence on government spending for military/naval projects and renewable energy support programs, including tax incentives and international agreements that could change policy direction","Rapidly growing inventory levels (47% increase to $105.4M in 9 months) and deferred revenue concentration suggest execution risk in converting backlog to delivered revenue","Recent acquisition of Comtrafo and Megatran/NWL creates integration execution risk and increases debt exposure while company operates in capital-intensive manufacturing"]
