01. Other Events

Item 8.01. Other Events. On September 5, 2025, DTE Energy Company issued the following update to its previous disclosure relating to an environmental matter. In March 2019, the U.S. Environmental Protection Agency ("EPA") issued a Finding of Violation ("FOV") to EES Coke Battery, LLC ("EES Coke"), the Michigan coke battery facility that is a wholly-owned subsidiary of DTE Energy, alleging that the 2008 and 2014 permits issued by the Michigan Department of Environment, Great Lakes, and Energy ("EGLE") did not comply with the Clean Air Act. In September 2020, the EPA issued another FOV alleging EES Coke's 2018 and 2019 sulfur dioxide emissions exceeded projections and hence violated non-attainment new source review permitting requirements. EES Coke evaluated the EPA's alleged violations and believes that the permits approved by EGLE complied with the Clean Air Act. EES Coke responded to the EPA's September 2020 allegations demonstrating its actual emissions are compliant with non-attainment new source review requirements. On June 1, 2022, the U.S. Department of Justice ("DOJ"), on behalf of the EPA, filed a complaint against EES Coke in the U.S. District Court for the Eastern District of Michigan alleging that EES Coke failed to comply with non-attainment new source review requirements under the Clean Air Act when it applied for the 2014 permit. In November 2022, the Sierra Club and City of River Rouge were granted intervention. On May 20, 2024, the court granted a motion allowing the DOJ to amend their complaint to add EES Coke's parent entities, including DTE Energy, as defendants. The parent entities were added in an attempt to share in any potential liability; there are no additional claims alleged. The EPA filed a motion for partial summary judgment on liability that was granted by the trial court on August 25, 2025. EES Coke intends to appeal this determination and has requested certification for an interlocutory appeal to the Sixth Circuit Court of Appeals.
