The site cracks ethane and cracker liquids to make ethylene and propylene and converts them into low density and linear low density polyethylene for domestic, regional and export markets. A $3.4 billion specialty elastomers plant was added alongside the olefins and polyethylene units and started up in 2016, producing halobutyl rubber, styrene butadiene and polybutadiene rubber, EPDM, thermoplastic specialty polymers and carbon black.

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.

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-Jubail Petrochemical Company (Kemya) where a holder stated one, and are missing where no holder did.
