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 Sinopec SABIC Tianjin Petrochemical Company Limited (SSTPC) where a holder stated one, and are missing where no holder did.
