Editorial Methodology
We use company filings, annual reports, company statements and press reports, with primary sources preferred where available. Each financial row shows its recorded source. Full-year figures are separated from annualized run-rates, partial periods and forecasts; unaudited figures carry a label. Source detail varies by company, so check the linked material when the reporting basis matters.
Public companies may provide filings and annual reports. Private-company figures may come from statements or press coverage. A missing figure stays missing, and a source link should identify where its number came from.
We organize company records and review claims for strategic context, source quality and clarity. Pages show a review date where one is recorded.
Technical checks flag inconsistent figures and missing links. Editorial review of the underlying source remains necessary for claims those checks cannot verify.
