SUBSEQUENT EVENT

On November 1, 2026, DTE Energy entered into a definitive agreement to sell certain operations and assets of the DTE Vantage segment, including renewable gas recovery, wholesale power and renewables, and on-site energy projects, to institutional investors advised by the Global Infrastructure group at J. P. Morgan Asset Management, for approximately $3.0 billion, subject to customary purchase price adjustments. The retained Vantage operations primarily relate to coke operations. The transaction is subject to regulatory approvals and other customary closing conditions and is expected to close during the first half of 2027. Because the transaction had not closed as of the date these financial statements were issued, no gain has been recognized.
