Fiscal period ending 2025-12-31 versus 2024-12-31 — view filing on EDGAR →
Customer concentration has escalated sharply (top-5 now 44% of revenue, one customer at 19%) while the company simultaneously took on $250M in new debt from a zero-leverage base, materially shifting both revenue and balance-sheet risk in a single year. Regulatory headwinds broadened across export controls, tax scrutiny, and trade policy, with prior mitigation language removed and uncertainty language added throughout. The combined effect is a meaningfully worse risk profile across multiple dimensions, though no solvency or going-concern trigger is present.
