Private company
Who owns Tengizchevroil LLP (TCO)
One company in the researched set discloses a stake in Tengizchevroil LLP (TCO), none of it sized by anyone who discloses it. Tengizchevroil LLP (TCO) is private, so no 13F reports it: a 13F covers exchange listed positions only. These figures exist because each holder disclosed the stake in its own filings.
The disclosed stakes
One row per position. Where a holder reports the same company in two share classes, both rows are shown rather than summed, because the class is part of a position's identity.
Where each figure comes from
A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.
- Chevron Corporation. Ownership percentage is filed ('Chevron has a 50 percent equity ownership interest in TCO'). The 10-K states the carrying value of the TCO investment was about $62 million higher than Chevron's underlying equity in TCO's net assets at 31 Dec 2025, but does not state the carrying value itself, and the aggregate equity-method balance across all affiliates is not broken out by investee. value_usd is therefore null rather than estimated. source
What this page is not
It is not a complete register. It lists the holders who happen to be inside the researched set and disclosed the stake themselves. A private company can have many other shareholders, and nothing here rules them out: venture investors, founders and employees usually appear in no public filing at all. Percentages are of Tengizchevroil LLP (TCO) where a holder stated one, and are missing where no holder did.
