) plan, any subsequent vote or revocation received by the voting deadline will supersede your prior vote. For example, if you voted by telephone, a subsequent Internet vote will change your vote. Deadlines for voting are indicated on the proxy card or meeting notice.

If you are a Registered Shareholder and wish to change your vote using a new proxy card, please call 1.866.388.8558 to request a new proxy card.

Registered Shareholders may also change their vote on their registered shares by voting at the annual meeting.

If you wish to revoke any prior vote you must submit a letter addressed to our tabulator, EQ, P.O. Box 64873, St. Paul, MN 55164-9397. It must be received prior to the meeting to be processed.

Beneficial Shareholders should contact their brokerage firm, bank or other nominee regarding the timing and method to change or revoke their vote.

#### DTE ENERGY2025 PROXY STATEMENT69

#### Is my vote confidential?
Yes, your vote is confidential. Your vote is received and counted by the tabulator and inspector of election, EQ. Your vote will not be disclosed except as required by law or in other limited circumstances.

#### Will I receive an Annual Report?
DTE Energy no longer provides a separate “Annual Report.” The Company’s Form 10-K, filed with the SEC, is provided to Shareholders with the proxy materials and serves as our “Annual Report” to our Shareholders.

What does it mean if I get more than one set of proxy materials or meeting notices?

In addition to reducing mailing costs by providing meeting notices, we also try to reduce costs relating to mailing duplicate sets of proxy materials by a method called householding. See “What is “householding” and how am I affected?” below. Despite these efforts, you may receive multiple copies of proxy materials if your shares are registered differently (i.e. trust, joint, name spelling variation, etc.) or if they are in more than one account (i.e., broker, bank, transfer agent, etc.). Please vote all proxies that you receive and consider consolidating your accounts.

If you are a Registered Shareholder receiving multiple sets of materials and wish to consolidate your accounts please contact EQ at 1.866.388.8558 .

If you are a Beneficial Shareholder receiving multiple sets of materials and wish to consolidate your accounts, please contact your brokerage firm, bank or other nominee.
