Who owns Atlantic Methanol Production Company LLC (AMPCO)
One company in the researched set discloses a stake in Atlantic Methanol Production Company LLC (AMPCO), none of it sized by anyone who discloses it. Atlantic Methanol Production Company LLC (AMPCO) 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.

Atlantic Methanol Production Company operates a world scale methanol plant at the Punta Europa gas complex on Bioko Island in Equatorial Guinea. Running since 2001 on natural gas from the offshore Alba field, it turns out more than one million metric tons of methanol a year, a little over one percent of world supply, which is shipped from the island for use as a chemical feedstock and fuel component. The venture pairs subsidiaries of ConocoPhillips and Chevron, which bring the upstream gas and the operating expertise, with the Equatorial Guinean state gas company SONAGAS. As Alba field output declines, the government has commissioned feasibility work on replacing the methanol plant with a modular crude oil refinery on the same site.

Atlantic Methanol Production Company LLC (AMPCO) files nothing with the SEC, so none of this comes from a filer record. The description was written for this site in August 2026 from About Atlantic Methanol Production Company, Equatorial Guinea to convert methanol plant to modular refinery (Hydrocarbon Engineering) and Equatorial Guinea proposes Punta Europa modular refinery (Oil & Gas Journal). The ownership figures below come from the holders' filings instead, and are sourced row by row.
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.
- ConocoPhillips. No carrying value is disclosed for AMPCO anywhere in the FY2025 10-K or the Q2 FY2026 10-Q; only the 45 percent ownership interest is stated (FY2025 10-K, Item 1/2 business description). The position is deliberately left unsized rather than estimated. The Q2 FY2026 10-Q does not contain the string 'AMPCO' at all. 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 Atlantic Methanol Production Company LLC (AMPCO) where a holder stated one, and are missing where no holder did.
