DETROIT, Oct. 30, 2025 /PRNewswire/ -- DTE Energy (NYSE:DTE) invested nearly $3 billion in its utilities through the third quarter of 2025 and remains on target to invest a total of $4.4 billion this year. These investments are focused on upgrading and modernizing the company's electric and natural gas infrastructure and transitioning to cleaner power generation to provide its customers with energy that is safer, cleaner, more reliable and more affordable.

The company also reported third quarter earnings of $419 million or $2.01 per diluted share, compared with $477 million, or $2.30 per diluted share in 2024. Operating earnings for the third quarter 2025 were $468 million, or $2.25 per diluted share, compared with 2024 operating earnings of $460 million, or $2.22 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.

"Our dedicated team of nearly 10,000 employees has taken on the challenge of leading Michigan's energy transformation, while keeping our electric bills and our natural gas rate lower than the national average for our customers," said Joi Harris, DTE Energy's president and CEO. "As we accelerate investments in cleaner energy and strengthen the safety and resiliency of our infrastructure, we are also generating enough reliable power to not only meet our customers' immediate needs, but power Michigan's future growth and prosperity."

Harris added, "We remain heavily focused on keeping our customers' bills as low as possible as we invest in our system. The data center agreement is a great step forward in executing our long-term strategy while also creating substantial affordability benefits for existing customers."

Harris also noted the following accomplishments:

Executed 1.4 GW data center agreement: The company recently finalized its first data center contract with a hyperscaler for 1.4 GW of load that will ramp up over the next two to three years. The new electricity demand will be supported with existing capacity and new energy storage investments which will be paid for by the data center. This data center growth will create substantial affordability benefits for existing customers as DTE sells excess generation, and contract terms will also ensure that the data center absorbs all new costs required to serve them.
Invested nearly $3 billion in our utilities through the third quarter of 2025: So far this year, DTE has invested significantly to build the electric grid of the future; transitioning to smart grid technology, modernizing and rebuilding infrastructure and trimming trees. Customers are seeing the benefits, for example, DTE's smart grid devices have prevented more than 17,500 outages throughout the company's service territory through the first three quarters of 2025. Accelerating the deployment of these smart devices is a critical component to DTE's investment plan and delivering on its commitment to reduce power outages by 30% and cut outage time in half by the end of 2029.
Supported vulnerable customers during extreme summer heat with $800,000 donation to United Way: DTE Energy donated $800,000 to United Way for Southeastern Michigan to help residents in need across the state stay safe during Michigan's extreme summer weather. The donation will provide relief to elderly, unemployed, underemployed, and disabled customers across Michigan who are struggling to pay their energy bills and have qualified for energy assistance in the current year.
Published annual Sustainability Report: DTE published its 2024 Sustainability Report, highlighting its progress toward expanding renewable energy, reducing carbon emissions, improving business operations, maintaining affordable energy for its customers and developing a skilled workforce to build a cleaner, more resilient energy future for Michigan.

Outlook for 2025 and 2026

DTE Energy confirms 2025 operating EPS guidance of $7.09 - $7.23. DTE Energy also provided a 2026 operating EPS early outlook guidance range of $7.59 - $7.73.

"We continued our strong financial performance through the third quarter of 2025, enabling us to invest above our generated cash flows into Michigan's energy infrastructure and deliver long-term value for the customers and communities we serve," said David Ruud, DTE vice chairman and CFO.

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 2025 and 2026 operating earnings guidance. It is likely that certain items that impact the company's 2025 and 2026 reported results will be excluded from operating results. Reconciliations to the comparable 2025 and 2026 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).
