For those Shareholders receiving paper copies of the Form 10-K and proxy statement, the SEC permits delivery of a single copy of these statements to Shareholders who have the same address and last name. This procedure, called “householding,” reduces the volume of duplicate information mailed and reduces printing and postage costs.

Despite “householding” of printed material, each Shareholder living at the same address will continue to receive a separate proxy card.

Registered Shareholders and DTE Energy 401(k) plan Participants: If you prefer to receive separate copies of our annual reports and proxy statements, now or in the future, please submit a written request to: EQ, Attn: Householding/DTE Energy, P.O. Box 64854, St. Paul, MN 55164-0854. Separate sets of documents will be promptly delivered to you.

Beneficial Shareholders can request information about “householding” by contacting their brokerage firm, bank or other nominee of record.

Can I elect to receive or view DTE Energy’s annual report (Form 10-K) and proxy statement electronically?

Yes. If you are a Registered Shareholder and you received printed proxy materials, you may elect to receive future proxy materials electronically. To do so you must provide your consent and enroll in this service at investorelections.com/dte , where step-by-step instructions will prompt you through the enrollment process.

By consenting to electronic delivery, you are stating that you currently have, and expect to have, access to the Internet. If you do not currently have, or do not expect to have, access to the Internet, please do not elect to have documents delivered electronically.

If you have previously enrolled, you will receive an email notification directing you to the website where you can view, search and print the annual report and proxy materials and vote your shares.

If this is your first time registering for electronic delivery, your enrollment will be effective for the 2026 annual meeting.

Beneficial Shareholders should contact their brokerage firm, bank or other nominee and inquire about their electronic delivery options.

All DTE Energy Shareholders can view, search and print the current year’s proxy statement and Form 10-K at proxydocs.com/dte .
