About this data
US-listed companies must disclose revenue from any single customer that reaches 10% of their total (ASC 280). ShadowGraph reads these disclosures from the XBRL data of every 10-K and 20-F we scan, keeps one value per fiscal year (restatements replace earlier values) and links each number to its filing. Companies that describe a customer only as "Customer A" are not listed by name. Figures are as reported; nothing here is investment advice.
