Margin VolatilitySharp swings in gross and net margins across years create uncertainty about sustainable profitability. For a high-volume diagnostics model, volatile margins weaken predictability of cash flows, complicate capacity planning and pricing strategy, and raise the execution bar for management.
Uneven Free Cash Flow GrowthAlthough recent FCF surged, historical unevenness signals that cash generation can be episodic. Irregular FCF complicates multi-year investment plans, dividend consistency, and debt repayment pacing, reducing the reliability of cash-backed strategic initiatives.
