Saudi Aramco is the national oil company of Saudi Arabia, based in Dhahran. The government owns about 81.5% directly and the Public Investment Fund about 16%, with the rest held by public investors on the Saudi Exchange. It produces roughly one in ten barrels of the world's oil, runs refining and chemicals assets on several continents, and pays the largest dividends of any listed company. Its market value was about $1.6 trillion in late September 2026. The company is headquartered in Dhahran, Saudi Arabia.
Aramco makes money across two main segments. Upstream explores for and produces crude oil, condensate, natural gas and natural gas liquids, mainly from Saudi fields such as Ghawar and Safaniya, and sells them to domestic and international customers. Downstream refines crude, trades and markets fuels, and makes chemicals through SABIC, Motiva in the US, S-Oil in South Korea and joint ventures in China. Upstream generates most of the profit. The Saudi state collects royalties, income tax and dividends, which makes Aramco central to government finances and Vision 2030 funding.

Al-Naimi, who joined Aramco as a boy, became the first Saudi chief executive in 1988.
He left in 1995 to become Saudi Arabia's oil minister, a post he held until 2016.
Saudi Aramco faces oil-price volatility, OPEC+ production decisions, geopolitical and security risk, energy-transition pressure, major capital spending demands, and petrochemical-cycle swings.
Amin H. Nasser has served as President and Chief Executive Officer of Saudi Aramco since September 2015. A petroleum engineer who joined Aramco in 1982, Nasser orchestrated the 2019 IPO, the $69.1B SABIC acquisition, and Aramco's transition into gas and chemicals.
Ali Al-Naimi was the first Saudi national to become President and CEO of Saudi Aramco, serving from 1983 to 1995. Having joined Aramco at age 12 as an office boy in 1947, he earned a geology degree at Stanford and led Aramco through full Saudi nationalization before serving as Saudi Minister of Petroleum for two decades (1995-2016).
Thomas Barger was a mining engineer and geologist who served as Aramco's President and CEO from 1959 to 1969. Barger was a visionary champion of the Saudi workforce, establishing modern schooling, housing, healthcare, and formal training that paved the way for Saudi self-governance of the company.
Frank Jungers served as CEO from 1973 to 1978. He successfully navigated the delicate geopolitical tensions during the 1973 Arab oil embargo and negotiated the initial agreements that allowed the Saudi government to peacefully acquire equity participation in Aramco.
Abdallah S. Jum'ah led Saudi Aramco as CEO from 1995 to 2009. His tenure was defined by the aggressive globalization of Aramco's downstream presence, establishing key refining joint ventures in the United States, South Korea, China, and Japan.
Khalid A. Al-Falih served as CEO from 2009 to 2015. He spearheaded the construction of mega-refining and petrochemical complexes like Sadara (JV with Dow) and Petro Rabigh, founded the King Abdullah Petroleum Studies and Research Center (KAPSARC), and later became Saudi Minister of Energy.
Yasir O. Al-Rumayyan has served as Chairman of the Board of Saudi Aramco since 2019. He is also the Governor of the Public Investment Fund (PIF), ensuring deep strategic alignment between Aramco and the Kingdom's Vision 2030 economic transformation.
Aramco operates an intensive, multi-decade succession pipeline: promising Saudi engineers and managers are sponsored at top global universities (MIT, Stanford, Imperial College), rotated through harsh field outposts, and tested in international joint venture boardrooms before reaching senior leadership.
John Kelberer was Aramco's last American Chairman and CEO, leading the company through the late 1970s and 1980s until 100% government ownership was solidified and operations were fully transferred to Ali Al-Naimi and a Saudi executive team.
Following the devastating 2019 drone strikes on Abqaiq and Khurais, CEO Amin Nasser mobilized over 6,000 emergency contractors and engineers, managing 24/7 reconstruction that brought 5.7M bpd of capacity back online within weeks, earning widespread praise for crisis management.
Due to Aramco's immense technical prestige and rigorous operational standards, the CEO seat serves as the premier training ground for Saudi energy statesmen; both Ali Al-Naimi and Khalid Al-Falih transitioned directly from running Aramco to leading the Ministry of Petroleum/Energy.
Amin Nasser is an outspoken global voice advocating for a realistic, multi-speed energy transition. He frequently cautions against premature disinvestment in oil and gas, arguing that cutting hydrocarbons before clean alternatives scale leads to inflation, energy insecurity, and increased coal consumption.
