Sharp Gross-margin CollapseA sudden, severe gross-margin deterioration undermines the core economics of device sales and consumables. If structural (pricing, cost increases, or product mix issues), it can erode sustainable profitability, reduce funds available for reinvestment, and question the durability of historical margin levels even if revenues continue.
Weak Cash-flow QualityRepeated negative free cash flow and a drop in operating cash in 2025 indicate uneven cash conversion and higher reinvestment or working-capital needs. Over time this can constrain organic growth, force external financing or equity raises, and limit the company's ability to self-fund placements and service expansion.
Returns And Efficiency DeteriorationNegative ROE after sizeable equity expansion signals weak capital efficiency and that incremental capital is not producing returns. Persistently low or negative returns risk investor dilution concerns and may reflect structural issues in pricing, cost control, or deployment effectiveness across regions or channels.
