Status: Largest U.S. oil company by market cap
Founded: 1999 (Exxon-Mobil merger)
ExxonMobil is the largest publicly traded oil and gas company in the United States and one of the largest in the world. The company was formed in 1999 through the merger of Exxon and Mobil, both descendants of John D. Rockefeller's Standard Oil Company.
As a major integrated oil company, ExxonMobil is involved in all aspects of the petroleum industry: exploration and production (upstream), refining and marketing (downstream), and chemicals manufacturing. This diversification provides financial stability that benefits mineral owners through consistent operations and reliable royalty payments.
ExxonMobil's acquisition of Pioneer Natural Resources in 2024 transformed the company into the dominant Permian Basin operator. The combined entity holds approximately 1.4 million net acres in the Permian and produces over 1.3 million barrels of oil equivalent per day from the basin alone. If you previously received royalties from Pioneer, your payments now come from ExxonMobil.
