Who owns Cogentrix Co-Investment Fund, LP
One company in the researched set discloses a stake in Cogentrix Co-Investment Fund, LP, worth $289m between them. Cogentrix Co-Investment Fund, LP 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.
- The Williams Companies, Inc., as of 30 Jun 2026. Equity-method limited partnership interest, not denominated in shares, so shares is null. Q2 2026 10-Q, Note 2 (Variable Interest Entities): 'The Cogentrix investment represents an approximate 10 percent indirect interest in 11 natural gas power plants... At June 30, 2026, the carrying value of our investment in Cogentrix was $289 million.' Purchased March 2025; the investee is accounted for as an investment company at fair value, so this carrying value already reflects an announced agreement to sell a significant portion of the underlying power plant assets. 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 Cogentrix Co-Investment Fund, LP where a holder stated one, and are missing where no holder did.
