Persistent Cash BurnSustained, large negative operating and free cash flow requires ongoing financing or rapid revenue scaling. Persistent burn limits optionality, raises dilution risk, and forces prioritization across programs, constraining long-term investment flexibility if commercial traction slows.

Even if granted, payer policy rollouts and confirmatory outcomes will materially affect durable uptake and revenue realization over multiple quarters.
