## History

The company began operations in December 2007 with the acquisition of 4,174 net acres in the Permian Basin. In October 2012, the company became a public company via an initial public offering, issuing 12,500,000 shares of common stock at a price of $17.50 per share at its opening on Nasdaq under the ticker symbol FANG, in reference to a snake's tooth; the company's logo at the time featured a Western diamondback rattlesnake.

In March 2017, the company acquired assets from Brigham Resources for $2.55 billion. In October 2018, the company acquired the assets of Ajax Resources for $1.25 billion. In November 2018, the company acquired Energen.

In February 2021, the company acquired leasehold interests and assets from Guidon Resources for $375 million in cash and 10.68 million shares. In March 2021, the company acquired QEP Resources.

In October 2023, the company was accused of being a major contributor to the increase of flaring gas in the Permian Basin.

In January 2024, a class action lawsuit was filed accusing Diamondback, along with seven other US oil and gas producers, of an illegal price fixing scheme to constrain production of shale oil, allegedly causing drivers in the US paying more for gasoline than they would have in a competitive market. The case is now part of a consolidated multidistrict litigation in New Mexico to be heard by judge Matthew L. Garcia. In September 2024, the company acquired Endeavor Energy Resources.

In April 2025, the company acquired Double Eagle IV for $3 billion in cash and 6.9 million shares of stock.
