•Began operations at Michigan’s largest wind park

•Partnered with Toyota to provide clean energy for the automaker’s research and development operations

•Granted $3 million to feed Michiganders through the DTE Foundation

DETROIT, April 27, 2023 – DTE Energy (NYSE:DTE) today reported first quarter earnings of $445 million or $2.16 per diluted share,compared with $394 million, or $2.03 per diluted share in 2022.

Operating earnings for the first quarter 2023 were $274 million, or $1.33 per diluted share, compared with 2022 operating earnings of $448 million, or $2.31 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.

“Earlier this year, we experienced the most challenging two-week storm period we have ever faced as a company. I am proud and grateful for how our team showed up for our customers by keeping each other and our communities safe. We understand the growing needs of our customers and communities,” Jerry Norcia, DTE Energy chairman, president and CEO, said. “We are continuing to strengthen our grid to be able to stand up to increasingly severe weather patterns and growing energy demands. We are also investing in clean energy and will always be a strong supporter of our communities, including Michigan businesses, to ensure we are working to create the best future for everyone.”

Norcia noted the following accomplishments:

•Investing heavily in utility infrastructure: DTE Electric invested over $750 million in the first quarter on continued improvements in reliability and cleaner energy generation for its customers while DTE Gas invested over $170 million on infrastructure and main renewal improvements.

•Commissioning Meridian Wind Park, the largest in Michigan: Located in three townships spanning Midland and Saginaw counties, the 225-megawatt wind park has 77 wind turbines and generates enough clean energy to power more than 78,000 homes. The project is DTE's first self-developed renewable energy project since 2016 and brings the total number of DTE wind and solar parks to 53.

•Partnering with Toyota to support clean energy in the automotive industry: Toyota Motor North America (TMNA) and DTE Energy announced Toyota’s enrollment in MIGreenPower, DTE’s voluntary renewable energy program. Toyota’s participation puts all TMNA’s research and development operations in Michigan on a path to attribute 100% of their electricity use to renewable energy projects starting in 2026. The 20-year agreement includes the company’s R&D headquarters in Ann Arbor, along with six other facilities across Washtenaw County.

•Supporting the United Way with a $3 million grant: The DTE Energy Foundation announced a $3 million grant to United Way for Southeastern Michigan and partner agencies to help feed area Michiganders. As food insecurity continues to rise and assistance programs decline, this support for meals and critical nourishment will help bridge the gap for families in need.

•Saving customers money by reducing gas rates: DTE Energy reduced its Gas Cost Recovery rate at the beginning of the year, based on its natural gas purchasing strategy and the decline in natural gas prices. DTE passes the cost for natural gas directly to its customers, with no additional cost, meaning customers pay what DTE pays.

•Launching skilled-trade academy: DTE Energy partnered with Walker-Miller Energy Services, one of the country’s largest African American and woman-owned energy efficiency companies, to launch the Energy Efficiency Academy. The Academy directly responds to the growing demand for energy-efficient home repairs in Detroit, while also building a local workforce that will benefit the community for years to come.

•Recognized as a Gallup Great Workplace for 11th consecutive year: DTE was recognized by Gallup as a workplace with exceptionally high employee engagement – in the top decile of Gallup’s worldwide database of companies.

Outlook for 2023

DTE Energy reaffirms 2023 operating EPS guidance of $6.09 - $6.40.

“We are executing on our 2023 plan while delivering for our team members, communities, customers and shareholders,” David Ruud, DTE senior vice president and CFO, said.

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 2023 operating earnings guidance. It is likely that certain items that impact the company's 2023 reported results will be excluded from operating results. Reconciliations to the comparable 2023 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.

IRP and rate case filing prioritize electric reliability with a focus on decarbonization and affordability 1. Definition of net zero included in the appendix 17 • IRP filing (U-21193) prioritizes electric reliability with a focus on decarbonization and affordability − Outlines generation transformation to achieve carbon reduction of 85% in 2035, 90% by 2040 and net zero1 by 2050 − Supports the Michigan economy and tax base with power generated in Michigan − Invests $9 billion over the next 10 years into Michigan’s economy supporting more than 25,000 jobs − Reduces cost of clean energy transition by $1.4 billion from previous plan • Electric rate case filing (U-21297) underpins reliability and cleaner generation investments − Second general rate case filing since 2019; executed significant customer- focused investments since that date while keeping base rates essentially flat − Majority of filing is attributable to capital, sales and the cost of debt − Continue practice of pursuing settlement with all stakeholders

1Q 2022 and 1Q 2023 reconciliation of reported to operating earnings (non- GAAP) and operating EPS (non-GAAP) 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 18 (Earnings per share2) Adjustments key A) 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 B) Adjustment to Income Tax Expense due to a tax law change in West Virginia

Reconciliation of reported to operating earnings (non-GAAP) 19 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.
