Item 8.01. Other Events.

On February 18, 2026, DTE Energy Company ("DTE Energy") issued the following update to its previous disclosure relating to an environmental matter.

On June 1, 2022, the U.S. Department of Justice, on behalf of the U.S. Environmental Protection Agency ("EPA"), filed a complaint against EES Coke Battery, LLC ("EES Coke"), the Michigan coke battery facility that is a wholly-owned subsidiary of DTE Energy, 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. 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 EPA filed a motion for partial summary judgment on liability that was granted by the trial court on August 25, 2025. Trial was held on remedies and parent liability, and concluded on September 29, 2025. On February 17, 2026, the trial court issued an order imposing a $100 million civil penalty on the defendants, including DTE Energy. The court also ordered the defendants to seek a permit for the installation of pollution controls and to establish and fund an action committee for community air quality improvement projects. The defendants will appeal this judgment and cannot predict the final outcome or additional financial impact of this matter.
