DTE Energy Company (DTE Energy) is furnishing the Securities and Exchange Commission (SEC) with its earnings release issued October 30, 2025, announcing financial results for the quarter ended September 30, 2025. A copy of the earnings release and the slide presentation, including supplemental financial information, are furnished as Exhibits 99.1 and 99.2 and incorporated herein by reference.

Item 7.01. Regulation FD Disclosure.

In its earnings release, slide presentation and this filing, DTE Energy discusses 2025 and 2026 operating earnings guidance.

These items may fluctuate significantly from period to period and may have a significant impact on reported earnings.

In accordance with General Instruction B.2 of Form 8-K, the information in this Current Report on Form 8-K, including Exhibits 99.1 and 99.2, shall not be deemed "filed" for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section, nor shall they be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, except as shall be expressly set forth in such a filing.
