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.
- Kinder Morgan, Inc., as of 31 Dec 2025. Equity-method joint venture interest, not a share count. FY2025 10-K states 50% ownership and a $1,660 million carrying value at 31 Dec 2025 ($1,734 million at 31 Dec 2024). Q2 2026 10-Q gives only the combined Investments total, not a per-investee split. source
- The Southern Company, as of 30 Jun 2026. Carrying (equity-method) value, not fair market value: this LLC is private and has no traded shares.

Q2 FY2026 10-Q reports $1,220 million at 30 June 2026; the FY2025 10-K reports $1,148 million at 31 December 2025 and $1,245 million at 31 December 2024.

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 Southern Natural Gas Company, L.L.C. (SNG) where a holder stated one, and are missing where no holder did.
