Chord Energy Corp

Operations Update:

•4-Mile Laterals: As of 3Q26, the Company has turned in line 47 total 4-mile wells. Execution and production results continue to be in line with expectations, supported by multi-well efficiencies. Chord has scaled its 4-mile program throughout 2026, with 70% of its lateral footage drilled as 4-mile wells, as of September 30, 2026.

•Execution: Chord continues to demonstrate strong operational execution and improved cycle times across its Williston Basin program. The Company continues to drive 4-mile efficiencies, with 70% of its laterals being drilled in a single run. As compared to 2025, Chord’s 2026 frac productivity has improved by over 20%, achieving a mile per day of completed lateral length in 3Q26. Cleanouts continue to reach total depth, ensuring contribution from the toe.

•Production/LOE: Continued execution improvements on base production helped drive production above the high-end of guidance. This has been driven by a broad set of initiatives across logistics, mechanical optimization, returning shut-in wells to production, and various chemical treatments. The team continues to generate new ideas, aided by AI screening tools, and Chord is testing multiple new approaches within its chemical workover program.
