A trusted architect of institutional transformation, he combines deep financial expertise with the exceptional ability to navigate and shape complex, high-stakes environments at the highest levels of government and industry.

As Group CEO of Oilfields Supply Center, Abdulnasser has been the driving force behind the organisation’s evolution, repositioning it from a legacy industrial player into a future-ready enterprise built on operational excellence, governance, and sustainable growth.
