Income statement figures describe a whole year; balance sheet figures describe a single day, so the two answer different questions. ## Where These Numbers Come From Every figure on this page is a value Korro Bio Inc. reported in its own SEC filings, read from the SEC's XBRL data (accession 0001193125-26-104156 for fiscal year 2025). Ratios are computed from those reported values. Figures were retrieved on October 7, 2026; a later amendment or a new annual report can change them, and the filing itself always takes precedence over this summary. Each fiscal year is labeled by the calendar year in which it ended, so a company that names the same period differently in its own filings (many retailers whose year ends in January) may use another label. A year is left out of the table when the SEC data set holds no value for it. A figure shown as "Not reported" means the company did not file a value under the standard tag Swoopr reads, not that the amount was zero. This page is educational and describes reported history only; it is not a forecast or a recommendation. ## Frequently Asked Questions ### What was Korro Bio Inc.'s revenue in fiscal 2025?
