ExxonMobil's primary brands are Exxon, Mobil, Esso, and ExxonMobil Chemical, which produces plastic, synthetic rubber, and other chemical products. ExxonMobil is incorporated in New Jersey.

Exxon Mobil Corp. engages in the exploration, development, and distribution of oil, gas, and petroleum products. It operates through the following segments: Upstream, Downstream and Chemical. The Upstream segment produces crude oil and natural gas. The Downstream segment manufactures and trades petroleum products. The Chemical segment offers petrochemicals.

As of 2007, it had daily production of 3.921 million BOE (barrels of oil equivalent). In 2008, this was approximately 3% of world production, which is less than several of the largest state-owned petroleum companies. When ranked by oil and gas reserves, it is 14th in the world—with less than 1% of the total. ExxonMobil's reserves were 20 billion BOE at the end of 2016 and the 2007 rates of production were expected to last more than 14 years. With 37 oil refineries in 21 countries constituting a combined daily refining capacity of 6.3 million barrels (1,000,000 m3), ExxonMobil is the seventh largest refiner in the world, a title that was also associated with Standard Oil since its incorporation in 1870.

In America, ExxonMobil has stations in 46 states, just behind Shell Oil Company and ahead of Phillips 66, lacking a presence only in Alaska, Hawaii, Iowa, and Kansas.

Esso is ExxonMobil's primary gasoline brand worldwide except in Australia, Guam, Mexico, Nigeria, and New Zealand, where the Mobil brand is used exclusively. In Canada (from 2017), Colombia, Egypt, and formerly Japan (now switched to ENEOS EneJet from 2019) and Malaysia (now switched to Petron from 2013), both the Esso and Mobil brands are used.

ExxonMobil also conducts research on clean energy technologies, including algae biofuels, biodiesel made from agricultural waste, carbonate fuel cells, and refining crude oil into plastic by using a membrane and osmosis instead of heat. However, it is unlikely the company will commercialize these projects before 2030.

In Global 2000 2022 list of Forbes, ExxonMobil was ranked 11 in Sales, 22 in Profit, 128 in Assets, and 20 in Market value.
