PETRONAS to Assume Full Ownership of PRefChem

KUALA LUMPUR, 25 May 2026 — PETRONAS announces that its subsidiary, PETRONAS Refinery and Petrochemical Corporation Sdn. Bhd. (PRPC) has signed an agreement to acquire the equity stake held by Saudi Arabian Oil Company (“Aramco”) in Pengerang Refining Company Sdn. Bhd. and Pengerang Petrochemical Company Sdn. Bhd. (collectively referred to as “PRefChem”), located within the Pengerang Integrated Complex, Pengerang, Johor. Subject to the fulfilment of customary closing conditions, PRefChem will become wholly owned and operated by the PETRONAS Group of companies. 

Recent developments in global energy markets have underscored the importance of operational agility for energy infrastructure of strategic national significance. Full ownership of PRefChem strengthens PETRONAS’ ability to support Malaysia’s long-term energy security and industry resilience. 

This acquisition will enable PETRONAS to take full control and further enhance operational alignment and flexibility across PRefChem’s value chain, while harnessing its international oil supply network and integrated operating model to support continued reliability and resilience across varying market conditions. Separately, crude supply arrangements between Aramco and PETRONAS under existing commercial agreements remain unaffected by this transaction. 

PETRONAS remains steadfast in its commitment to Malaysia’s energy security and to building the international presence and partnerships that will position Malaysia as a progressive energy nation for decades to come.
