Negative Cash FlowConsistent negative operating and free cash flow is a structural constraint: the business consumes cash rather than generating it. The 2025 FCF deterioration (~13% YoY) highlights ongoing burn and implies continued dependence on external funding absent sustained revenue scale or material cost reduction.
Persistent LossesSizable operating and net losses each year produce deeply negative margins and no self-funding path. Persistent unprofitability elevates dilution risk from future capital raises, constrains reinvestment in programs, and increases execution risk for advancing internal vaccine candidates long term.
Eroding Equity BaseMaterial contraction in equity and total assets over multiple years signals cumulative losses that weaken the balance sheet. Reduced asset and equity cushions limit borrowing headroom, reduce resilience to setbacks, and constrain the firm's ability to finance development or scale operations without dilution.
