Updated September 30, 2026. Read from SEC Financial Statement Data Sets (sec.gov). Public data from the US Securities and Exchange Commission. Companies are the registrants whose latest annual report (form 10-K, 20-F or 40-F) is in the SEC Financial Statement Data Sets for 2025 Q3 to 2026 Q3, filed through September 30, 2026. Figures are for the whole fiscal year of that report, in US dollars, as the company filed them in XBRL: SpecStream does not adjust them. The SEC does not guarantee the data sets, and they do not replace the filings. Revenue is the revenue tag the company used; banks and funds often use none. Combined totals add each company once and can include a parent and its subsidiary that both file. Free to reuse with credit to SpecStream under CC BY 4.0. Spot a wrong value?
