Summary

DTE Energy Co. (DTE) filed a Form 8-K on June 22, 2026, primarily to disclose that the company will be meeting with investors on June 23, 2026. A slide presentation, previously furnished on May 15, 2026, will be used in these investor discussions and is being referenced again in this filing. The presentation contains information regarding DTE Energy's 2026 operating earnings guidance. Investors should note that the guidance provided for 2026 operating earnings may exclude certain items that will impact reported results. DTE Energy states that reconciliations for these excluded items are not provided due to the inability to reliably forecast specific line items such as future non-recurring items, certain mark-to-market adjustments, and discontinued operations. These excluded items can significantly impact reported earnings, so investors should be aware of the distinction between operating and reported earnings when evaluating the guidance.
