Risk Radar (year-over-year Risk Factors)

← All Risk Radar

Fiscal period ending 2026-03-31 versus 2025-03-31view filing on EDGAR →

Regulatory and tax risk has materially broadened, with new concrete exposures spanning IRS dual-taxation challenges, GloBE safe harbor ineligibility, OBBBA Medicaid funding cuts, and multi-jurisdictional carbon pricing — while the removal of Section 7874 risk is offset by a net increase in tax complexity. Competitive and strategic risks also escalated, with new customer insourcing threats in the AST segment and expanded M&A/JV/divestiture obligations adding operational complexity. The one meaningful easing (Section 7874 removal) is more than counterbalanced by the breadth of new and escalated exposures across regulatory, tax, competitive, and strategic themes.
