Official sources
US records come from the SEC EDGAR APIs. Korean records come from OpenDART. Each financial period and filing links to its official source.
Annual financials
US figures use standard US GAAP concepts in consolidated annual reports (10-K). Fiscal years differ between companies. Korean figures use current-period amounts in consolidated (CFS) annual reports. Separate statements are not silently substituted for missing consolidated data.
Revenue growth = (current − previous revenue) / previous revenue × 100, only when the previous value is positive. Operating margin = operating income / revenue × 100, only when revenue is positive and operating income is available.
Amendments and comparability
For the same fiscal period, the most recently filed standard fact takes precedence. Amendments and reclassifications can change historical values. Accounting definitions, fiscal calendars, currencies and business structures differ. Currency amounts are not converted. Financial-sector revenue and operating results may not be comparable to non-financial businesses.
When these figures were collected
Collection is a script that calls the SEC EDGAR and OpenDART APIs directly, and its result is published with the site. Every company page shows which fiscal years were collected and when the report behind them was filed; those are two different dates. Annual statements change when a company files, and the data is refreshed on that rhythm. No real-time prices or mid-quarter figures are offered.
