Margin CompressionSteep, sustained margin erosion signals structural cost inflation or pricing pressure that weakens cash generation per revenue unit. If persistent, margin compression undermines returns on incremental expansion, constrains reinvestment, and raises sensitivity to volume swings.
Negative Free Cash FlowPersistently negative FCF driven by higher capex can strain liquidity and force external financing or equity dilution to fund growth. Over the medium term, continued negative FCF reduces flexibility for dividends, deleverages balance sheet, and raises refinancing risk if revenue growth falters.
Concentration In Single SpecialtyHeavy reliance on one medical specialty concentrates exposure to ophthalmic demand cycles, reimbursement shifts, and competitor moves. Limited service diversification reduces cross-selling opportunities and makes overall cash flows more sensitive to specialty-specific regulatory or technological changes.
