Key Metrics

Shrinking cash cushion versus burn
Metrics are mathematically derived from official filings.
Cash Depletion Erodes Balance Sheet Strength
According to reported figures, Korro Bio's total assets fell from $249.6M in 2024Q2 to $163.4M in 2026Q2, with cash dropping from $138.8M to $24.9M, signaling a balance sheet that is weakening as operating losses consume reserves.
The decline in total assets is driven overwhelmingly by cash depletion rather than asset build-out, which suggests the company is funding persistent operating losses from its existing capital base. Equity has contracted from $198.1M to $103.2M over the same window, reflecting accumulated deficit growth that has pushed retained earnings to -$422.4M. Investors should monitor whether the trajectory reflects a deliberate funding runway or an unsustainable draw on reserves.
Thin Cash Buffer Against Quarterly Burn
Based on reported figures, Korro Bio held $24.9M in cash at 2026Q2 against a free cash outflow of $33.1M in that quarter, leaving the cash position covering less than one quarter of recent burn despite a current ratio of 9.55.
The headline current ratio of 9.55 appears strong but is inflated by a small liability base relative to current assets, and it does not reflect the speed at which cash is being consumed. Cash has fallen from $61.7M in 2026Q1 to $24.9M in 2026Q2, a sharp reduction that warrants close monitoring. Based on these figures, the company's near-term liquidity position appears highly sensitive to any further delay in financing or adverse development outcomes.
Low Leverage Offset by Limited Cash Support
As reported in financial statements, Korro Bio carried $42.2M in total debt at 2026Q2 against $60.2M in total liabilities, producing a debt-to-equity ratio of 0.41 that looks modest but sits against a thin cash base.
Debt-to-equity has risen from 0.19 in 2024Q2 to 0.41 in 2026Q2 as equity has shrunk faster than debt, which suggests leverage is increasing mechanically rather than through strategic borrowing. The debt load remains stable in absolute terms at roughly $36M to $45M across the window, so the concern is less about the size of obligations and more about the declining capacity to service them from operations. Refinancing or repayment terms are not visible in the supplied data and warrant further investigation.
Accumulated Deficit Dominates Equity Base
Based on Korro Bio's reported figures, retained earnings deficit grew from -$202.6M in 2024Q1 to -$422.4M in 2026Q2, while book equity declined to $103.2M, indicating losses are consuming paid-in capital.
The steady expansion of the accumulated deficit by roughly $20M to $50M per quarter indicates that equity is being eroded by operating and non-operating losses. Because book equity is falling alongside the deficit, the company's equity cushion is shrinking in real terms rather than being replenished by earnings. The data does not show share issuance details, so dilution effects cannot be assessed from the balance sheet alone.
Deferred Revenue Collapse Masks Revenue Visibility
According to recent SEC filings, Korro Bio's deferred revenue fell from $10.0M in 2024Q3 to $1.0M in 2026Q2, which may indicate that contracted revenue visibility has largely disappeared from the balance sheet.
Deferred revenue has been zero in several earlier quarters and only $1.0M in the latest period, so the balance sheet offers little forward evidence of contracted customer cash. This may leave the company dependent on financing rather than collaboration income to fund operations. Investors should treat the low headline liability base with caution, as it reflects absence of forward commitments rather than balance sheet strength.
