Pertamina

With $75.9 billion in revenue, state-owned oil and gas producer Pertamina is Indonesia’s largest company. In addition to extraction and refining, Pertamina sells petrol to the country’s fuel-hungry consumers–sometimes at subsidized prices due to inflation concerns from Jakarta. Pertamina’s president director, Nicke Widyawati, is the highest-ranked woman chief executive on the Southeast Asia 500.
