Map details

Choosing Street map loads OpenStreetMap’s tile service. Provider terms and data sources.

    Company sizes are equal because this snapshot has no market-cap data. Thicker lines indicate larger reported shares; dashed lines have no comparable total share recorded. Check each filing’s measurement basis before comparing.

    Customer and supplier sources

    Select one or more companies on the map or from the list to read the filing text behind each of their links.

    Company records and sources

    Ownership, facilities, procurement and carrier relationships, for the selected companies only.

      Current coverage is counted from the database when you open these layers.

      Property disclosures carry the granularity each filing used — individual sites, cities, regions or worldwide summaries — so a facility record is not the same thing as a geocoded address. Federal-award summaries cover one recipient registration and all award types, not a contracts-only company total.

      Which companies have records?

      Collection is selective: a few companies have been reviewed and the rest have not been looked at yet. This list is built from the live coverage index and names every company that has at least one record, so you can go straight to a populated layer instead of hunting for one.

      The company detail records have not been read yet.

      Switch on a company detail layer and select a company to read these records.

      How to read this map

      A disclosed sample

      Companies must report revenue concentration when a customer accounts for 10% or more of revenue, but they need not name that customer. Some also name smaller customers voluntarily. This map includes a reviewed sample of named relationships found in SEC filings. Missing links do not establish that two firms have no business relationship.

      Read the measurement basis

      Percentages may refer to net sales, gross sales, continuing operations or sales through intermediaries. Each evidence card identifies the reported basis. Joint percentages and figures covering only part of a business are left out of the line-width calculation.

      Direction and geography

      Network arrows run from supplier to customer. On the globe and in the Street map view a line joins two current headquarters cities; it is not a shipping route. The evidence distinguishes direct relationships from end customers reached through another party.

      Company detail is per company, and separate

      The ownership, facility, procurement and carrier-relationship layers are a different body of evidence from the disclosed customer links, and they behave differently. A carrier-relationship record is a shipping arrangement a company named in a source document — a carrier it uses, a route it describes, a logistics agreement it discloses. Nothing on this page tracks an individual shipment or consignment, and no live freight movement is shown. They show records only for the companies you have selected; nothing is aggregated across the index and nothing is carried from one company to another. In Network view, records appear as connected symbols without claiming a geographic position. Globe and Street map markers require a location precise enough to verify, so a facility pin never reuses the parent company’s head office as a stand-in. Where a layer is empty for a company, the panel never prints a zero against it, because a zero reads as a count somebody took. It says instead which of two things is true: Not yet collected, meaning no source has been reviewed for that company and that layer, or Reviewed source: no verified record, meaning a source was read and named nothing of that kind. Only a coverage entry naming that company and that layer can produce the second wording; the dataset’s general caveats never stand in for a company having been checked. An empty layer means nothing has been recorded here, not that the company has nothing of that kind.

      Check the source

      Automated source checks matched each excerpt to its filing. Open the original document to review the context before using a relationship in an analysis. Index membership and headquarters locations reflect the dated snapshot below.

      Sources and attribution

      Network visualization: Cytoscape.js (MIT license). Globe and Street map land outlines: Natural Earth, public domain. The Street map view loads only when you choose it, and its base map is then served as tiles by OpenStreetMap under that project’s own terms, with its attribution shown on the map itself. Nothing on this page draws traffic, transit, cycling or any other live service layer, and no map provider account is involved.

      Company detail records — ownership, facilities, procurement and carrier relationships — are loaded from the live reviewed-record database. Each record links to the document it was taken from, and each says where in that document it was found. A record is drawn on the map only when the source records a position precise enough to place; records without a verified position appear as connected symbols in Network view and remain available in the source list.
