Who owns Al Waha Petrochemical Company
One company in the researched set discloses a stake in Al Waha Petrochemical Company, none of it sized by anyone who discloses it. Al Waha Petrochemical Company 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.

Al Waha Petrochemical Company runs a propane dehydrogenation and polypropylene complex in Jubail Industrial City in eastern Saudi Arabia. Formed in 2006 by Sahara Petrochemical, now part of Sahara International Petrochemical Company (Sipchem), together with LyondellBasell, it takes locally supplied propane, converts it to propylene in a PDH unit and polymerises it in a plant built on LyondellBasell's Spherizone technology. Commercial operation began in 2009 with propylene capacity of about 465,000 tonnes and polypropylene capacity of about 450,000 tonnes a year. An expansion contracted in August 2024 lifts those figures to 537,000 and 600,000 tonnes, with completion scheduled for the fourth quarter of 2026. Its resins go into automotive parts, fibre and food packaging.

Al Waha Petrochemical Company 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 Sipchem awards SAR 634M EPC contracts for Al Waha plant (Argaam), New polypropylene plant based on LyondellBasell's Spherizone process technology (Plastemart), Al-Waha Petrochemical Opens 450,000-Ton Polypropylene Plant in Al-Jubail Industrial City (Industrial Info Resources), Saudi's Al-Waha to start up Al-Jubail PP, PDH units on 6 May (ICIS, 2009) and Saudi's Sipchem awards $169 million expansion of PDH-PP Plant Project (SaudiGulf Projects). 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 Arabie Investissements SAS owns a 25% interest in Al Waha Petrochemical Company. This is a 25 percent ownership interest, written here as the number 25, not as a fraction of 100. Cross-checked against Note 10 (Equity Investments) of the same 10-K, which lists 'Al-Waha Petrochemicals Ltd.' at 25.00% 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 Al Waha Petrochemical Company where a holder stated one, and are missing where no holder did.
