Based on FY2025 annual data. Scores normalized against common benchmarks. How we calculate these scores
Altimmune has an operating margin of -230461.0%, meaning the company retains $-230461 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 up from -515860.0% the prior year.
Altimmune's revenue surged 105.0% year-over-year to $41K, reflecting rapid business expansion. This strong growth earns a score of 100/100.
Altimmune carries a low D/E ratio of 0.15, meaning only $0.15 of long-term debt for every $1 of shareholders' equity. This conservative leverage earns a score of 99/100, indicating a strong balance sheet with room for future borrowing.
With a current ratio of 18.55, Altimmune holds $18.55 in current assets for every $1 of short-term obligations. This comfortable liquidity earns a score of 100/100.
While Altimmune generated -$67.5M in operating cash flow, capex of $11K consumed most of it, leaving -$67.5M in free cash flow. This results in a low score of 0/100, reflecting heavy capital investment rather than weak cash generation.
Altimmune generates a -39.2% ROE, indicating limited profit relative to shareholders' investment. This results in a returns score of 0/100. This is up from -77.0% the prior year.
Altimmune passes 4 of 9 financial strength tests. 2 of 4 profitability signals pass, 1 of 3 leverage/liquidity signals pass, both operating efficiency signals pass.
For every $1 of reported earnings, Altimmune generates $0.77 in operating cash flow (-$67.5M OCF vs -$88.1M net income). This low ratio suggests earnings are primarily driven by accounting accruals rather than cash generation, which may not be sustainable.
Altimmune earns $-57.8 in operating income for every $1 of interest expense (-$94.5M vs $1.6M). This narrow margin raises concern about the company's ability to service its debt if operating income declines.
