DETROIT, Feb. 17, 2026 /PRNewswire/ -- DTE Energy $(DTE)$ announced today that it made record capital investments in 2025 of more than $4.3 billion to improve the reliability of its utility infrastructure and generate cleaner energy for its customers. DTE Electric invested over $3.6 billion toward boosting reliability and building cleaner energy generation, while DTE Gas invested $661 million to upgrade its natural gas system. Beyond these investments, DTE secured a landmark agreement to power Oracle's new data center development, which is expected to produce significant affordability benefits for its electric customers and drive economic progress in Michigan.

The company also reported 2025 earnings of nearly $1.5 billion, or $7.03 per diluted share, compared with $1.4 billion, or $6.77 per diluted share in 2024. Operating earnings for 2025 were $1.5 billion, or $7.36 per diluted share, compared with 2024 operating earnings of $1.4 billion, or $6.83 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 achievements in 2025 are a testament to the hard work and passion of our entire DTE team," said Joi Harris, DTE president and CEO. "In 2025, we delivered historic gains for our customers and communities - reducing power outages, advancing Michigan's transition to clean energy and investing with local businesses. Securing an agreement to power Oracle's new data center will create long-term benefits for all our customers, demonstrating our commitment to affordable, reliable energy and economic growth for Michigan. As we take on new opportunities, we will continue our commitment to deliver innovative solutions and cost savings for our customers."

Harris noted the following accomplishments:

   -- Secured landmark agreement to power Oracle's new data center: DTE 
      negotiated its first hyperscale data center contracts to provide 1.4 
      gigawatts of load to power Oracle's new data center in Saline Township, 
      MI, paving the way to deliver significant affordability benefits to its 
      customers. The contracts, approved by the Michigan Public Service 
      Commission, protect DTE customers by ensuring revenues from Oracle cover 
      the costs associated with powering the data center, so DTE's existing 
      customers will not subsidize data center rates. By bringing a large 
      customer like Oracle onto its electric system, DTE can spread fixed costs 
      more broadly and provide substantial affordability benefits for existing 
      customers. Additionally, the agreement protects customers from any risk 
      of stranded assets. This historic project is the largest economic 
      development initiative in Michigan's history and will generate thousands 
      of local jobs. 
 
   -- Continued improving electric reliability: During 2025, DTE Electric made 
      major investments to improve the reliability and resiliency of the grid, 
      installing nearly 700 smart devices, rebuilding key sections of the grid, 
      upgrading poles, cross-arms, and other critical infrastructure, and 
      trimming nearly 6,600 miles of trees. Building on the 70% reduction in 
      outage time from 2023 to 2024, these enhancements, coupled with less 
      extreme weather, contributed to an additional 60% improvement in 2025. 
      DTE also restored power faster than ever during storms through strategic 
      planning and process improvements. DTE's ongoing investments remain 
      crucial to ensuring its grid is ready for future opportunities like 
      growing electric demand. 
 
   -- Enhanced safety and affordability for natural gas customers: DTE Gas 
      continued to enhance the safety and reliability of its system while 
      keeping energy affordable for customers. The company upgraded more than 
      180 miles of gas main with more efficient and durable pipe that ensures 
      the ongoing safe and reliable delivery of natural gas, as well as 
      benefits the environment by preventing leaks. Ongoing revenue growth from 
      DTE's Home Protection Plus appliance program continues to offset costs 
      for gas utility customers. 
 
   -- Advanced clean energy development: DTE began construction on the Cold 
      Creek Solar Park in Branch County, a key initiative supporting Ford Motor 
      Company's transition to 100% carbon-free manufacturing through DTE's 
      Clean Vision MIGreenPower program. DTE completed construction of the Pine 
      River and Polaris Solar Parks in Gratiot County, which collectively 
      provide clean energy to more than 43,000 homes and are funded by 
      voluntary customer enrollments in MIGreenPower. DTE also partnered with 
      the city of Detroit to build Castle Solar Park and offset electricity use 
      in city buildings. These projects advance DTE Electric's net zero carbon 
      emissions goal and help Michigan reach its new standard of 60% renewable 
      energy by 2035. 
 
   -- Invested $2.9 billion in local businesses, including a record $1.1 
      billion with Detroit suppliers: DTE spent $2.9 billion with local 
      businesses in 2025, creating and sustaining an estimated 13,000 jobs 
      across Michigan. For the first time in its history, the company spent 
      more than $1 billion with Detroit-based businesses. DTE continues to be a 
      leader in partnering with local suppliers, investing more than $24 
      billion since 2016 and creating or sustaining more than 100,000 Michigan 
      jobs. 
 
   -- Earned honors as a great place to work: DTE received Gallup's Exceptional 
      Workplace Award for the 13th consecutive year, placing DTE in the top 3% 
      of companies globally. 
 
   -- Connected vulnerable customers to $125 million in energy assistance: In 
      2025, DTE helped vulnerable and income-qualified customers access $125 
      million in energy assistance through partnerships with nonprofit agencies 
      across Michigan. Additionally, DTE donated $15 million to The Heat and 
      Warmth Fund, The Salvation Army and United Way for Southeastern Michigan 
      to provide critical support to elderly, unemployed, underemployed, 
      disabled and other residents in need across the state. 
 
   -- DTE Energy Foundation granted $300,000 to feed hungry families: 
      Responding to the disruption in Supplemental Nutrition Assistance Program 
      (SNAP) benefits and a continued surge in food insecurity statewide, DTE 
      Energy Foundation awarded $300,000 to food programs to help meet the 
      growing demand for meals amid persistent economic challenges. The funds 
      were distributed among organizations serving communities throughout DTE's 
      service territory, including Food Bank of Eastern Michigan, Food 
      Gatherers, Forgotten Harvest, Gleaners Community Food Bank, United Way 
      and Feeding America West Michigan. 

Outlook for 2026

DTE Energy confirms its 2026 operating EPS guidance of $7.59 - $7.73.

"DTE's strong results in 2025 reflect our disciplined strategy and commitment to delivering value for our customers and shareholders," said David Ruud, DTE's vice chairman and CFO. "The investments we made this year not only strengthened our core operations and enhanced reliability for our customers, they also laid a secure foundation for continued growth and success in 2026 and beyond."
