Exxon Mobil’s roots trace back to John D. Rockefeller’s Standard Oil Company, founded in 1870. Following Standard Oil’s breakup in 1911 due to antitrust laws, two of its largest successors, Standard Oil of New Jersey (Exxon) and Standard Oil of New York (Mobil), merged in 1999 to form the modern-day giant. This merger created the world’s largest non-state-owned energy company.

ExxonMobil is one of the world’s largest publicly traded integrated oil and gas companies (a “Supermajor”). Its operations span the entire energy value chain: exploration and production of oil and gas (upstream), refining and chemical manufacturing (downstream), and marketing. While maintaining its core oil and gas business, the company also aims to play a role in the global energy transition by investing in low-carbon solutions such as carbon capture and storage, hydrogen, and biofuels.
