Who owns Louisiana Integrated PolyEthylene JV LLC
One company in the researched set discloses a stake in Louisiana Integrated PolyEthylene JV LLC, none of it sized by anyone who discloses it. Louisiana Integrated PolyEthylene JV LLC 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.

Louisiana Integrated PolyEthylene JV LLC holds and operates part of the petrochemical complex at Westlake, near Lake Charles in Louisiana. Its assets are an ethane cracker able to produce about 1.5 million tonnes of ethylene a year and two adjoining plants that turn that ethylene into roughly 0.9 million tonnes a year of low density and linear low density polyethylene, together with the shared infrastructure that serves them. The venture does not sell on its own account: it toll manufactures for its two members, LyondellBasell and Sasol, each of which takes half the output. LyondellBasell runs the plants day to day and markets the polyethylene for both. It was created on 2 December 2020, when Sasol sold half of the assets it had built at Lake Charles and about 400 of its employees there transferred to LyondellBasell.
Source
Louisiana Integrated PolyEthylene JV LLC 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 LyondellBasell and Sasol Complete Louisiana Joint Venture Transaction (Sasol), LyondellBasell and Sasol Complete Louisiana Joint Venture Transaction (PR Newswire) and LyondellBasell Industries N.V. Form 10-K exhibit 21, list of subsidiaries (sec.gov). 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.
- LyondellBasell Industries N.V.. Exhibit 21.1 to the FY2025 10-K (filed 20 Feb 2026) states that LyondellBasell LC Offtake LLC owns a 50% interest in Louisiana Integrated PolyEthylene JV LLC. This is a 50 percent ownership interest, written here as the number 50, not as a fraction of 100. Cross-checked against Note 10 (Equity Investments) of the same 10-K, which lists 'Louisiana Joint Venture' at 50.00% ownership as of both 31 Dec 2025 and 31 Dec 2024, confirming the figure independently within the same filing. LyondellBasell's balance sheet carries a single combined 'Equity investments' line ($3,963 million at 31 Dec 2025 per the 10-K; $3,875 million at 30 Jun 2026 per the most recent 10-Q) covering all equity-method investees together, so no individual carrying value is disclosed for this venture: value_usd is null. sourcesource 2
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 Louisiana Integrated PolyEthylene JV LLC where a holder stated one, and are missing where no holder did.
