Chord Energy Corp.

Chord Energy Corporation, a Delaware Corporation (together with our consolidated subsidiaries, the Company, Chord, we, us, or our ), is an independent exploration and production ( E&P ) company engaged in the acquisition, exploration, development and production of crude oil, NGL and natural gas primarily in the Williston Basin with limited non-operated interests in the Marcellus Shale. Our mission is to responsibly produce hydrocarbons while exercising capital discipline, operating efficiently, improving continuously and providing a fun and rewarding environment for our employees. We are ideally positioned to generate strong free cash flow and enhance return of capital, while being responsible stewards of the communities and environment where we operate. On May 31, 2024, we acquired Enerplus Corporation, a corporation existing under the laws of the Province of Alberta, Canada ( Enerplus ) in a stock-and-cash transaction (such transaction, the Arrangement ). The results of operations and reserves data presented herein report the results of legacy Chord from January 1, 2023 through May 30, 2024 and the results of Chord (including legacy Enerplus) from May 31, 2024 through December 31, 2025, unless otherwise noted. As of December 31, 2025, we had 1,302,921 net leasehold acres in the Williston Basin, approximately all of which is held by production. We are currently exploiting significant resource potential from the Middle Bakken and Three Forks formations, which are present across a substantial portion of our acreage.
