Financial Health Signals
Based on FY2025 annual data. Scores normalized against common benchmarks. How we calculate these scores
Gossamer Bio has an operating margin of -352.2%, meaning the company retains $-352 of operating profit per $100 of revenue. This below-average margin results in a low score of 0/100, suggesting thin profitability after operating expenses. This is down from -52.2% the prior year.
Gossamer Bio's revenue declined 57.7% year-over-year, from $114.7M to $48.5M. This contraction results in a growth score of 0/100.
Gossamer Bio's current ratio of 2.64 indicates adequate short-term liquidity, earning a score of 50/100. The company can meet its near-term obligations, though with limited headroom.
While Gossamer Bio generated -$171.3M in operating cash flow, capex of $79K consumed most of it, leaving -$171.3M in free cash flow. This results in a low score of 0/100, reflecting heavy capital investment rather than weak cash generation.
Gossamer Bio passes 0 of 9 financial strength tests. No profitability signals pass, no leverage/liquidity signals pass (rising debt, declining liquidity, or share dilution), neither operating efficiency signal passes.
For every $1 of reported earnings, Gossamer Bio generates $1.01 in operating cash flow (-$171.3M OCF vs -$170.4M net income). This low ratio suggests earnings are primarily driven by accounting accruals rather than cash generation, which may not be sustainable.
Gossamer Bio earns $-15.5 in operating income for every $1 of interest expense (-$170.7M vs $11.0M). This narrow margin raises concern about the company's ability to service its debt if operating income declines.
