About
Diamondback Energy is one of the largest and lowest-cost oil producers in the Permian Basin, founded in 2007 and headquartered in Midland, Texas, trading on Nasdaq (FANG). The company completed the landmark acquisition of Endeavor Energy Resources in September 2024 for approximately $26 billion—the largest private company acquisition in Permian Basin history—transforming Diamondback into the third-largest Permian producer behind ExxonMobil-Pioneer and Occidental Petroleum. Pro forma for Endeavor, Diamondback produces approximately 880,000 barrels of oil equivalent per day from its combined Midland and Delaware Basin acreage. CEO Travis Stice, a founding team member, has built Diamondback through disciplined bolt-on acquisitions and operational efficiency from a small Permian pure-play into a basin titan.
