Deep Fission, Inc. (FISN) Financials
A multiple compares the market's price with a filed figure; it says what the market pays, not how the business is doing. The market capitalization is the vendor's as of Sep 17, 2026; every other figure is from the SEC filings on this page. Not financial advice.
Newest figures come from the 10-Q for Q2 FY2026, filed Aug 3, 2026. Each column of the statement tables below links to the filing it was taken from, and every filing is listed on the FISN SEC filings page.
This page shows Deep Fission, Inc. (FISN) financial statements, including the income statement, balance sheet, cash flow statement, and key financial ratios. View 2 years of annual fundamentals and quarterly data, with year-over-year growth rates and compound annual growth rates (CAGR). All figures are derived from SEC filings (10-K and 10-Q reports).
Deep Fission’s reported profile is dominated by liability growth and negative equity, not observable operating activity.
From FY2022 to FY2023, assets expanded 11.2x while liabilities increased 1.8x, so the balance-sheet expansion came with heavier obligations rather than clear strengthening. The equity deficit widened from a$62K deficit to a$109K deficit, confirming that added assets did not restore net worth.
Current liabilities equaled total liabilities in both years, while the current ratio remained far below 1x; obligations were concentrated in the short-term bucket relative to reported current assets. The ratio improved mechanically as assets increased, but not enough to change that structure.
Revenue, net income, and operating cash flow are unreported for both annual periods, so the available statements cannot establish operating scale or cash-conversion quality. Without profitability, cash-flow, or capital-spending figures, reinvestment needs and earnings quality also cannot be evaluated.

Not reported in any period shown, so not listed: Gross Margin, Operating Margin, Net Margin, Asset Turnover, FCF Margin.
Note: Shareholder equity is negative (-$109K), which causes debt-to-equity and return on equity ratios to appear negative or not meaningful. This can occur from accumulated losses or large share buyback programs.
Note: The current ratio is below 1.0 (0.01), indicating current liabilities exceed current assets, which may suggest potential short-term liquidity concerns.
