Frequently Asked Questions

The primary purpose of this 8-K filing is to inform investors about an upcoming meeting where DTE Energy will discuss its 2026 operating earnings guidance and to reference the slide presentation that will be used.

Operating earnings, as presented by DTE Energy, are expected to exclude certain items that impact the company's overall reported results. These excluded items, such as non-recurring events, mark-to-market adjustments, and discontinued operations, can fluctuate significantly and may materially affect reported earnings.

DTE Energy states that reconciliations are not provided because it is not possible to reliably forecast the specific future amounts of these potentially significant and volatile line items (non-recurring items, mark-to-market adjustments, discontinued operations) that are excluded from operating earnings.
