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.

Devon Energy is an oil and gas producer with acreage in several top US shale plays. While roughly two-thirds of its production comes from the Permian Basin, it also holds a meaningful presence in the Anadarko, Eagle Ford, and Bakken basins. If the merger with Coterra is successful, it will have a foothold in the gas-driven Appalachian Basin, as well. At the end of 2025, Devon reported net proved reserves of 2.4 billion barrels of oil equivalent, up from 2.2 billion in 2024. Net production averaged roughly 840,000 barrels of oil equivalent per day in 2025 at a ratio of 73% oil and natural gas liquids and 27% natural gas.
