Chord Energy — May 5, 2026 release

Capital costs were in line with expectations, supported by multi-well efficiencies, including simulfrac operations. Early performance is in line with expectations. Chord is scaling its 4-mile development in 2026, with approximately 40% of TILs and 60% of spuds expected to be 4-mile laterals. The broader program is expected to benefit from continued multi-well execution efficiencies. • Execution: Chord continues to demonstrate strong operational execution and improving cycle times across its Williston Basin program. The Company remains the most active operator in the Bakken and the leader in the development of extended-reach laterals, including 4-mile wells. Drilling performance continues to improve, with the majority of 4-mile laterals successfully drilled in a single run, minimizing cycle times and driving cost efficiencies. Chord is also realizing cost savings from operating both its frac fleets on dual fuel, significantly reducing exposure to diesel price volatility. Completions execution remains strong, with consistent cleanout performance to total depth. Additionally, the Company continues to reduce facilities-related capital through infrastructure optimization, with the majority of the development program benefiting from equipment re-use and scalable facility design. • Production/LOE: Chord delivered strong production above expectations in 1Q26 through its disciplined base optimization efforts, focused on low-cost, high-r
