Diamondback Energy, Inc.

FANG

Diamondback is a crude oil and natural gas exploration and production firm whose operations represent a pure-play in the US Permian Basin. The company went public in 2012 and has established itself as a top-tier independent producer through disciplined acquisition and operational excellence. The company's most transformational transaction occurred in September 2024 with the completion of its $26 billion merger with Endeavor Energy Resources, which added around 470,000 net acres and doubled Diamondback's total acreage position. Diamondback boasts an enviable position in the Midland sub-basin, with some of the lowest unit costs among its Permian peers.
