Wisayah is the investment management arm of Aramco (Saudi Arabian Oil Company), based in Saudi Arabia. It manages Aramco’s financial assets and savings plans, providing asset management and treasury solutions for the company and certain affiliates. Wisayah invests across public and private markets to preserve and grow capital over the long term, under established governance and risk management frameworks.
While not an operator in chemicals, Wisayah allocates capital to sectors connected to Aramco’s energy and chemicals value chains—such as infrastructure, advanced materials, and industrial services—supporting the group’s strategic objectives and major projects. Its role is to deploy capital efficiently, diversify exposures, and support initiatives that strengthen Aramco’s broader portfolio, including petrochemicals and downstream activities.
