How this list is built
Revenue is total revenue as reported in each company's annual financial statements for its latest full fiscal year filed by 9 November 2026, in US dollars; fiscal years differ, so each entry shows its fiscal year end. Companies are included if their shares trade on a US stock exchange and their primary Standard Industrial Classification code is 3821, 3822, 3823, 3824, 3825, 3827, 3829; companies that report in another currency, including IFRS reporters that do not report in US dollars, are not included, and each figure was checked against the prior year, other reported revenue lines and total assets. Where a listed parent and a listed subsidiary both qualify only the parent is ranked, two listed entities that report the same consolidated results are counted once, and ties share a rank.
Every position is set by the data alone, by the same rules for every company. Spotted something to update? Write to info@stratummarketresearch.com with the list and the line, and we correct it within two working days.
