Group Structure
PLAINS ALL AMERICAN PIPELINE, L.P. sits 1 level below its ultimate parent, Plains GP Holdings, L.P., registered in United States. 45 subsidiaries are recorded beneath it, across 2 jurisdictions. The full chain up to Plains GP Holdings, L.P. is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by PLAINS ALL AMERICAN PIPELINE, L.P.'s own shareholder record. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 45 subsidiaries span United States, Canada jurisdictions, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear. Three of the 45 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
