Persistent High Cash BurnOperating cash flows and free cash flows are deeply negative and have persisted across multiple years. Even with current liquidity, sustained -$300M+ annual cash burn forces either rapid revenue scaling or external financing, increasing dilution or refinancing risk over the medium term if product uptake slows.

The volatility (an isolated profitable year amid large losses) reduces earnings quality and limits the firm's ability to generate returns on invested capital absent consistent commercial scale.
