Free Cash Flow VolatilityA sharp TTM swing to negative free cash flow and weak cash conversion undermines sustainability; heavy capex, working-capital drag or ramp-related inventory can persist while capacity scales. This weakens internal funding of growth, increases reliance on external capital, and elevates execution and liquidity risk during multi-quarter ramps.
Execution Risk On Production And QualificationNew 6-inch IP production, CPO and other product ramps are early-stage; while yields look promising, customer qualification, pilot-to-volume transitions, and scaling additional sites (e.g., Zurich) carry execution, timing and qualification risks that could delay revenue, compress margins, and prolong working-capital absorption.
Rising Operating Expense And R&D IntensityElevated operating expenses and higher R&D intensity are investing for long-term products but will pressure near-term operating leverage and cash generation until higher-volume sales materialize. If demand softens or ramps slip, margin targets and cash conversion could be harder to achieve.
