Fiscal period ending 2025-12-31 versus 2024-12-31 — view filing on EDGAR →
Risk exposure broadened materially across five distinct themes — government customer, regulatory, cyber, supply chain, and geopolitical — driven by new executive-order constraints, expanded cyber threat acknowledgment, and concrete tariff/trade policy disclosures. The single partial offset (removal of fixed-price contract loss risk) is modest against the weight and breadth of escalations. No solvency or going-concern signal is present, but the pervasiveness of worsening across operational and regulatory dimensions is substantive.
