Who owns Indelpro, S.A. de C.V.
One company in the researched set discloses a stake in Indelpro, S.A. de C.V., none of it sized by anyone who discloses it. Indelpro, S.A. de C.V. 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.

Indelpro, S.A. de C.V. produces polypropylene resins at the Altamira petrochemical complex on Mexico's Gulf coast, in the state of Tamaulipas. It runs the first polypropylene plant built in Mexico, has installed capacity of about 640,000 tonnes a year, and sells its resin under the Profax and Valtec names to converters serving packaging, fibre, automotive and appliance markets. The business is a joint venture between LyondellBasell, which supplies the polypropylene process technology, and Alpek, the petrochemical arm of the Mexican industrial group Alfa. Operations began in the early 1990s, the partners added a propylene splitter at Altamira in 1999 to secure monomer supply, and a second polypropylene line followed later in the decade that followed.

Indelpro, S.A. de C.V. 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 Our Story (Alpek), Indelpro, S.A. de C.V. company entry (chemeurope.com) and Third PP line coming, says Indelpro source (Plastics News). 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 Basell International Holdings B.V. owns a 49% interest in Indelpro, S.A. de C.V.. This is a 49 percent ownership interest, written here as the number 49, not as a fraction of 100. Cross-checked against Note 10 (Equity Investments) of the same 10-K, which lists 'Indelpro S.A. de C.V.' at 49.00% 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 Indelpro, S.A. de C.V. where a holder stated one, and are missing where no holder did.
