Item 2.02. Results of Operations and Financial Condition.

DTE Energy Company (DTE Energy) is furnishing the Securities and Exchange Commission (SEC) with its earnings release issued July 28, 2020, announcing financial results for the quarter ended June 30, 2020. 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. In its earnings release and the slide presentation discussed below, DTE Energy reaffirms its 2020 operating earnings guidance range of $6.47-$6.75.

Item 7.01. Regulation FD Disclosure.

DTE Energy is furnishing the SEC with its slide presentation issued July 28, 2020. A copy of the slide presentation is furnished as Exhibit 99.2 and incorporated herein by reference.

In its slide presentation and this filing, DTE Energy discusses 2020 operating earnings guidance. It is likely that certain items that impact the company's 2020 reported results will be excluded from operating results. Reconciliations to the comparable 2020 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). These items may fluctuate significantly from period to period and may have a significant impact on reported earnings.

DTE Energy also discusses Adjusted EBITDA in its slide presentation. The reconciliation of net income to Adjusted EBITDA as projected for full-year 2020 is not provided. DTE Energy does not forecast net income as it cannot, without unreasonable efforts, estimate or predict with certainty the components of net income.  These components, net of tax, may include, but are not limited to, impairments of assets and other charges, divesture costs, acquisition costs, or changes in accounting principles. All of these components could significantly impact such financial measures. At this time, DTE Energy is not able to estimate the aggregate impact, if any, of these items on future period reported earnings. Accordingly, DTE Energy is not able to provide a corresponding GAAP equivalent for Adjusted EBITDA and allocated debt.

In accordance with General Instruction B.2 of Form 8-K, the information in this Current Report on Form 8-K, including Exhibit 99.1, 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 it 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.

EXHIBIT 99.1

DTE Energy reports strong second quarter 2020 results;

continues progress in environmental goals

•DTE Gas joins DTE Electric in net zero emissions goal

•Brings state’s largest wind park online

•Partners with General Motors on Michigan’s largest renewable energy investment

DETROIT, July 28, 2020 – DTE Energy (NYSE:DTE) today reported second quarter 2020 earnings of $277 million, or $1.44 per diluted share, compared with $182 million, or $0.99 per diluted share in 2019.

Operating earnings for the second quarter 2020 were $295 million, or $1.53 per diluted share, compared with 2019 operating earnings of $183 million, or $0.99 per diluted share. Operating earnings exclude non-recurring items, certain mark-to-market adjustments and discontinued operations. Reconciliations of reported earnings to operating earnings are included at the end of this news release.

“During the first half of the year DTE responded swiftly to ensure our employees and customers were safe during the early months of the COVID-19 pandemic,” said Jerry Norcia, DTE Energy president and CEO. “I couldn’t be prouder of our employees’ efforts to meet the needs of our customers while at the same time focusing on keeping our company on track. As a result, we’re entering the second half of the year in great shape.”

Norcia also noted the following recent company accomplishments:

•Announced 2050 DTE Gas net zero goal: The unique and comprehensive plan reduces greenhouse gases by more than 6 million metric tons annually, the equivalent of removing 1.3 million gasoline-powered cars from the road. The plan is one of the first to address emission reductions both upstream with suppliers and with customers through emissions offset programs.

•Commenced operations at Michigan’s largest wind park; the first of four new wind parks coming online in 2020:New wind parkswill increase clean energy generation capacity by more than 50% in 2020 and will offset 1.2 million metric tons of CO₂ emissions annually.

•Partnered with General Motors on renewable energy investment: This investment delivers enough clean energy to supply GM’s Southeast Michigan facilities by 2023, including the Renaissance Center global headquarters in Detroit, the GM Global Technical Center in Warren, the Milford Proving Ground in Milford and two local assembly plants; Orion and Detroit-Hamtramck, as well as several smaller GM sites across Southeast Michigan.

•Provided bill relief to customers during peak summer usage months: $30 to $40 million in bill relief is being passed on to electric utility customers for June and July after leveraging efficiency and lower fuel prices to significantly reduce generation costs.

•Continued support of Michigan businesses: Invested over $1.1 billionwith Michigan-based companies in the first half of this year, executing its commitment to the Pure Michigan Business Connect local supplier initiative. This includes approximately $550 million invested in the city of Detroit.

Outlook for 2020

“The solid financial results achieved during the first half of the year give us confidence in achieving our 2020 earnings guidance with a strong second quarter offsetting a challenging first quarter,” said David Ruud, DTE Energy senior vice president and CFO. “The results in the second quarter are driven by strong performance across all of our businesses, cost reductions and warmer than normal weather.This provides a solid foundation for delivering on our financial and operational goals for this year.”

Additionally, DTE is releasing its 2020 Environmental and Social Governance report highlighting the company’s commitment to creating and sustaining long-term value for all stakeholders.

Use of Operating Earnings Information - DTE Energy management believes that operating earnings provide a more 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.

In this release, DTE Energy discusses 2020 operating earnings guidance. It is likely that certain items that impact the company's 2020 reported results will be excluded from operating results. Reconciliations to the comparable 2020 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). These items may fluctuate significantly from period to period and may have a significant impact on reported earnings.

DTE Energy also discusses Adjusted EBITDA in its slide presentation. The reconciliation of net income to Adjusted EBITDA as projected for full-year 2020 is not provided. DTE Energy does not forecast net income as it cannot, without unreasonable efforts, estimate or predict with certainty the components of net income.These components, net of tax, may include, but are not limited to, impairments of assets and other charges, divesture costs, acquisition costs, or changes in accounting principles. All of these components

could significantly impact such financial measures. At this time, DTE Energy is not able to estimate the aggregate impact, if any, of these items on future period reported earnings. Accordingly, DTE Energy is not able to provide a corresponding GAAP equivalent for Adjusted EBITDA and allocated debt.

Consists of 1) the income statement effect of not recognizing changes in the fair market value of certain non-derivative contracts including physical inventory and capacity contracts for transportation, transmission and storage. These contracts are not marked-to-market, instead are recognized for accounting purposes on an accrual basis and 2) operating adjustments for 26 unrealized marked-to-market changes of certain derivative contracts 3. Economic gross margin is the change in net fair value of realized and unrealized purchase and sale contracts including certain non-derivative contract costs

2019 – 2020 reconciliation of reported to operating earnings (non-GAAP) Use of Operating Earnings Information – DTE Energy management believes that operating earnings provide a more 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. Adjustments key A) MPSC disallowance of capital expenses previously recorded in 2018 and 2019 related to incentive compensation — recorded in Operating Expenses — Asset (gains) losses and impairments, net B) Shift premiums and other incremental costs associated with the sequestration of employees critical to continued operations due to COVID-19 — recorded in Operating Expenses — Operating and maintenance C) 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, and gas — non-utility D) Reduction to Income Tax Expense resulting from carrying back 2018 net operating losses to 2013 pursuant to the CARES Act E) MPSC approval of the deferral for the new customer billing system post- implementation expenses — recorded in Operating Expenses — Operation and maintenance F) MPSC disallowance of power plant capital expenses — recorded in Operating Expenses — Asset (gains) losses and impairments, net 1. Excluding tax related adjustments, the amount of income taxes was calculated using a combined federal and state income tax rate of 26% and 25% for Utility and Non-utility operations, respectively, for the three months ended June 30, 2020 and June 30, 2019 27

2019 – 2020 reconciliation of reported to operating EPS (non-GAAP) Use of Operating Earnings Information – DTE Energy management believes that operating earnings provide a more 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.

Per share amounts are divided by Weighted Average Common Shares Outstanding — Diluted, as noted on the Consolidated Statements of operations (Unaudited)

Reconciliation of reported to operating earnings (non-GAAP) 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 more 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. 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. 29

Adjusted EBITDA and Allocated Debt are non-GAAP measures Adjusted EBITDA is calculated using net income, the most comparable GAAP measure and adding back expenses for interest, taxes, depreciation and amortization. Adjusted EBITDA also includes an adjustment for DTE’s proportional share of joint venture net income, excluding taxes and depreciation. Allocated debt is calculated by excluding utility debt from DTE Energy debt, the most comparable GAAP measure, and allocating the residual debt. The GSP portion of the residual debt is allocated to achieve a 50/50 debt/equity structure with adjustments to accommodate off-balance sheet financing for joint venture investments. For GSP, DTE Energy management believes that Adjusted EBITDA is a meaningful disclosure to investors as it is more commonly used as the primary performance measurement for external communications with analysts and investors in the midstream industry. Allocated debt is a meaningful disclosure to provide visibility to GSP’s capital structure. Reconciliation of net income to Adjusted EBITDA as projected for full-year 2020 is not provided. We do not forecast net income as we cannot, without unreasonable efforts, estimate or predict with certainty the components of net income. These components, net of tax, may include, but are not limited to, impairments of assets and other charges, divesture costs, acquisition costs, or changes in accounting principles. All of these components could significantly impact such financial measures. At this time, management is not able to estimate the aggregate impact, if any, of these items on future period reported earnings. Accordingly, we are not able to provide a corresponding GAAP equivalent for Adjusted EBITDA. Similarly, reconciliation of DTE Energy debt to GSP allocated debt is not provided. We do not forecast debt as we cannot, without unreasonable efforts, estimate or predict it with certainty. Debt may be significantly impacted by DTE Energy’s cash flows. At this time, management is not able to estimate the aggregate impact of operating, investing, and other financing cash flows on future period debt. Accordingly, we are not able to provide a GAAP equivalent for allocated debt. 30
