High Cash Burn & Negative Operating Cash FlowThe company is still consuming significant cash to grow: TTM operating cash flow and free cash flow are deeply negative, and Q1 cash burn (~$25M) remains material. Even with improving revenue, persistent negative cashflow creates reliance on existing liquidity and potential future financing until margins and scale fully offset spend.
Deep Ongoing Losses And Negative MarginsDespite revenue momentum, the business remains structurally unprofitable with TTM net and EBIT margins near -60%. High operating intensity (S&M ~75% of revenue) and continued R&D investment mean returns remain negative, delaying self-sufficiency and pressuring long-term profitability unless cost structure shifts.
FDA Warning Letter And Remediation RiskAn FDA warning letter requires remediation work that can consume management attention, extend timelines and increase compliance costs. Because Mint commercialization and broader product expansion depend on regulatory clearances, unresolved FDA items pose a durable operational and execution risk that could delay launches or limit market access.
