Use of Operating Earnings Information - DTE Energy management believes that operating earnings provide a meaningful representation of the company’s earnings from ongoing operations and uses operating earnings as the primary performance measurement for external communications with analysts and investors. Internally, DTE Energy uses operating earnings to measure performance against budget and to report to the Board of Directors. Operating earnings is a non-GAAP measure and should be viewed as a supplement and not a substitute for reported earnings, which represents the company’s net income and the most comparable GAAP measure. In this release, DTE Energy discusses 2024 operating earnings guidance. It is likely that certain items that impact the company's 2024 reported results will be excluded from operating results. Reconciliations to the comparable

2024 reported earnings guidance are not provided because it is not possible to provide a reliable forecast of specific line items (i.e. future non-recurring items, certain mark-to-market adjustments and discontinued operations).

Forward-looking statements are not guarantees of future results and conditions but rather are subject to numerous assumptions, risks and uncertainties that may cause actual future results to be materially different from those contemplated, projected, estimated or budgeted.

1Q 2023 and 1Q 2024 reconciliation of reported to operating earnings (non- GAAP) and operating EPS (non-GAAP) 16 Adjustments key A) One-time costs resulting from the voluntary separation incentive program - recorded in Operating Expenses - Operation and maintenance B) Certain adjustments resulting from derivatives being marked-to-market without revaluing the underlying non-derivative contracts and assets — recorded in Operating Expenses — Fuel, purchased power, gas, and other — non-utility C) Adjustment to Income Tax Expense due to a tax law change in West Virginia 1. Excluding tax related adjustments, the amount of income taxes was calculated based on a combined federal and state income tax rate, considering the applicable jurisdictions of the respective segments and deductibility of specific operating adjustments 2. Per share amounts are divided by Weighted Average Common Shares Outstanding – Diluted, as noted on the Consolidated Statements of Operations (Unaudited) (Earnings per share2)

Reconciliation of reported to operating earnings (non-GAAP) 17 Use of Operating Earnings Information – Operating earnings exclude non-recurring items, certain mark-to-market adjustments and discontinued operations. DTE Energy management believes that operating earnings provide a meaningful representation of the company’s earnings from ongoing operations and uses operating earnings as the primary performance measurement for external communications with analysts and investors. Internally, DTE Energy uses operating earnings to measure performance against budget and to report to the Board of Directors. Operating earnings is a non-GAAP measure and should be viewed as a supplement and not a substitute for reported earnings, which represents the company’s net income and the most comparable GAAP measure. In this presentation, DTE Energy provides guidance for future period operating earnings. It is likely that certain items that impact the company’s future period reported results will be excluded from operating results. A reconciliation to the comparable future period reported earnings is not provided because it is not possible to provide a reliable forecast of specific line items (i.e., future non-recurring items, certain mark-to-market adjustments and discontinued operations). These items may fluctuate significantly from period to period and may have a significant impact on reported earnings. Definition of net zero Goal for DTE Energy's utility operations and gas suppliers at DTE Gas that any carbon emissions put into the atmosphere will be balanced by those taken out of the atmosphere. Achieving this goal will include collective efforts to reduce carbon emissions and actions to offset any remaining emissions. Progress towards net zero goals is estimated and methodologies and calculations may vary from those of other utility businesses with similar targets. Carbon emissions is defined as emissions of carbon containing compounds, including carbon dioxide and methane, that are identified as greenhouse gases.
