The Grissoms, LLC v. Antero Resources Corp., No. 24-3676 (6th Cir. 2025)
Annotate this Case
A certified class of Ohio landowners alleged that a Colorado-based mining company, Antero Resources Corporation, underpaid them $10 million in natural gas royalties. The landowners claimed that Antero improperly deducted costs for processing and fractionation from their royalties. Antero counterclaimed, seeking authority to deduct additional costs related to gathering, dehydrating, compressing, and transporting the unrefined natural gas. The district court certified the class, denied Antero's motion for summary judgment, granted the landowners' motion, and entered a final judgment after the parties stipulated damages.
The United States District Court for the Southern District of Ohio ruled in favor of the landowners, finding that Antero improperly deducted processing and fractionation costs from the royalties. The court determined that these costs were necessary to transform the gas into marketable form and thus could not be deducted under the lease agreement.
The United States Court of Appeals for the Sixth Circuit reviewed the case and affirmed the district court's decision. The court held that Antero could not deduct the costs of processing and fractionation from the landowners' royalties. The court found that the lease agreement's Market Enhancement Clause allowed deductions only for costs that enhanced the value of already marketable products, not for costs required to make the products marketable. The court concluded that the gas products first became marketable after processing and fractionation, and thus, these costs were not deductible. The court also noted that the Fourth Circuit had reached a similar conclusion in a related case involving the same defendant and lease terms.
