What company was created when Exxon and Mobil merged in 1999?

ExxonMobil was created when Exxon and Mobil merged in 1999.

The agreement joined two major descendants of John D. Rockefeller’s Standard Oil empire. Exxon had previously been known as Standard Oil of New Jersey, while Mobil descended from Standard Oil of New York. The merger received regulatory approval in 1999 and was completed on November 30, 1999.

The transaction created one of the world’s largest publicly traded oil and gas companies. Its businesses cover exploration, production, refining, fuels, chemicals and lubricants. The company is headquartered in Texas and operates brands including Exxon, Mobil and Esso in different markets.

A common mix-up is the completion date: the merger was announced in 1998, but the combined company began operating as ExxonMobil in 1999. ExxonMobil is also distinct from Chevron, which later absorbed Texaco in a separate major oil merger.
