Item 1. Legal Proceedings Solaris Water Midstream, LLC (“Solaris”), a subsidiary of Aris, and certain affiliates are named defendants in Cause No. 23-05-1085, Stateline Operating, LLC and Stateline Royalties, LP vs. Devon Energy Corporation, Stateline Water, LLC, Devon Energy Production Company, LP, Solaris Water Midstream, LLC, Solaris Midstream DB-TX LLC, and Aris Water Solutions, Inc. , in the 143rd District Court, Loving County, Texas, which was filed on May 4, 2023. In this action, Plaintiffs sue Defendants for, among other things, negligence, waste, trespass, and nuisance based on Plaintiffs’ allegations that Defendants’ operations have harmed Plaintiffs’ oil and gas lease through the injection of disposed saltwater. Defendants dispute Plaintiffs’ claims of liability and damages in this matter. There is currently no scheduled trial date as the previous trial date of September 14, 2026 was vacated by the Court in July 2026. The Court has also indicated that the case will be transferred to Reeves County, Texas. We have elected to use a $1.0 million threshold for disclosing certain proceedings arising under federal, state, or local environmental laws when a government authority is a party and potential monetary sanctions are involved. We believe proceedings under this threshold are not material to our business and financial proceedings. Other than the items listed herein, we are not a party to any legal, regulatory, or administrative proceedings other than proceedings arising in the ordinary course of business. Management believes that there are no such proceedings for which a final disposition could have a material adverse effect on results of operations, cash flows, or financial condition, or for which disclosure is otherwise required by Item 103 of Regulation S - K.
