Diamondback Energy, Inc.
An oil and natural gas producer whose operations are concentrated in the Permian Basin of West Texas, drilling horizontal wells across the region. Founded in 2007 and headquartered in Midland, Texas, the company took its name from the diamondback rattlesnake common to the area — hence its stock ticker, FANG. In 2024 it merged with Endeavor Energy, a neighbor headquartered literally across the street, to become one of the largest pure-play producers in the basin.
