Exhibit 99.1

DTE Energy reports second quarter earnings

•Received approval of landmark CleanVision Integrated Resource Plan (IRP) settlement agreement with Michigan stakeholders, ending DTE’s use of coal in 2032

•Continued progress with MIGreenPower program

•Invested heavily in infrastructure to improve reliability and generate more clean energy

•Named one of the top 50 most community-minded companies in the U.S. by Points of Light

•Partnered with Michigan Department of State to remove workforce barriers for Michiganders

•Planted over 4,300 trees during spring planting season with the Detroit Tree Equity Partnership, growing the benefits of a tree canopy in communities that need it most

DETROIT, July 27, 2023 – DTE Energy (NYSE:DTE) today reported second quarter earnings of $201 million or $0.97 per diluted share,compared with $37 million, or $0.19 per diluted share in 2022.

Operating earnings for the second quarter 2023 were $206 million, or $0.99 per diluted share, compared with 2022 operating earnings of $171 million, or $0.88 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.

DTE Energy recently reached a historic clean energy settlement agreement with stakeholders to transform energy generation and dramatically reduce carbon emissions.

“Our CleanVision Integrated Resource Plan outlines our investment in Michigan's future and we are grateful to the 21 organizations from across Michigan for their diligent work on this settlement agreement," said Jerry Norcia, DTE Energy chairman and CEO. "From ending the use of coal in 2032, to reducing future costs of our clean energy transformation by $2.5 billion, this plan is a roadmap to cleaner, more reliable and affordable energy for our customers."

Norcia noted the following accomplishments:

•Landmark CleanVision IRP will end DTE’s use of coal in 2032 while developing enough Michigan-generated renewables to power approximately four million homes: This plan accelerates DTE’s decarbonization goals, further accelerating the full retirement of the Monroe Power Plant from 2035 to 2032.DTE Electric plans to achieve 85% CO2

emission reductions in nine years with a goal of net zero carbon emissions by 2050.

•Continued progress with MIGreenPower program: Dakkota Integrated Systems enrolled in MIGreenPower, DTE’s voluntary renewable energy program. The enrollment will attribute 100% of the electricity use at Dakkota’s Detroit location to DTE’s wind and solar parks, which has the environmental benefit equivalent to the carbon captured by more than 1,500 acres of forests annually.

•Invested heavily in utility infrastructure: DTE Electric invested $1.5 billion in the first half of the year on continued improvements in reliability and cleaner energy generation for its customers while DTE Gas invested nearly $350 million on infrastructure and main renewal improvements.

•Received Civic 50 award: For six years in a row, the hard work and dedication of DTE’s team members have resulted in Points of Light naming DTE one of the top 50 most community-minded companies in the United States with its Civic 50 Award. Projects like the Tree Trim Academy, License Restoration Clinics and Community Network were pivotal in earning this recognition.

•Facilitated driver’s license restorations: DTE has joined with the Michigan Department of State and other organizations to help Michiganders with driving license issues at in-person license restoration clinics across the state. The “Road to Restoration” has helped 7,500 Michiganders, trained 100 volunteer attorneys and enlisted 15 Michigan nonprofits to help. DTE volunteers help staff these clinics and our legal department helps guide people through the process.

•Improved Detroit urban tree numbers bringing the benefits of a tree canopy to more in the city: The Detroit Tree Equity Partnership (DTEP) planted over 4,300 trees during the spring planting season – over 1,200 more trees than the initial goal. DTEP also added new trainees to its crew while focusing on planting along commercial corridors, parks, vegetative buffers and blighted areas. Growing Detroit’s tree canopy in these targeted areas means lower street-level temperatures, reduced flooding risk and fewer respiratory ailments in these communities.

Outlook for 2023

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

“Our 2023 plan is on track as we continue to deliver for our team members, communities, customers and shareholders,” David Ruud, DTE executive 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.

2Q 2022 and 2Q 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 17 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 (Earnings per share2)

Reconciliation of reported to operating earnings (non-GAAP) 18 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.
