Risk Radar (year-over-year Risk Factors)

← All Risk Radar

Fiscal period ending 2025-12-31 versus 2024-12-31view filing on EDGAR →

The risk profile broadened materially across seven distinct themes, with no single existential trigger but a clear pattern of escalating operational, regulatory, and technology exposure. The most substantive additions are agentic AI and IP risks, cloud infrastructure concentration, executive key-person vulnerability without insurance coverage, and new macro headwinds from tariffs and OBBBA tax changes. The one apparent easing—removal of matched principal, self-clearing, and sanctions risks—is offset by their simultaneous re-disclosure under the broader risk expansion, limiting confidence that these exposures are genuinely resolved.
