Fellow Shareholders,

We invite you to attend our company’s annual meeting of shareholders, which will be held in a virtual-only format on Thursday, May 8, 2025. Please see page 71 for details regarding attendance.

2024 was a breakthrough year for our company. We invested a historic $4 billion to modernize our infrastructure, as our team of nearly 10,000 employees made significant progress building the electric grid of the future, upgrading and expanding our natural gas pipelines and transforming our power generation to produce cleaner energy for our customers.

By bringing their best energy to work every day, DTE team members earned Gallup’s Exceptional Workplace award for the 12 th consecutive year, placing us in the top 6% of companies globally. Employees also put our new safety energy model into action, recognizing and controlling high-energy hazards in our workspaces and ensuring the safety of all team members.

Early in 2024, we made a bold commitment to our customers to reduce power outages by 30%, while cutting outage time in half by the end of 2029. This year alone, we made great progress. Our work to build a smarter, stronger and more resilient grid, coupled with less extreme weather, resulted in DTE customers experiencing a nearly 70% improvement in time spent without power from 2023 to 2024.

Our Gas team improved the lives of 1,000 new residential customers and 100 new businesses in Northern Michigan by expanding our service and transitioning these customers from propane heat to natural gas, which reduces their energy costs and their emissions. The team also ensured the continued delivery of safe and reliable natural gas to our 1.3 million DTE Gas customers by replacing more than 225 miles of cast iron pipes with more durable materials.

We accelerated our journey to deliver cleaner energy to our customers by breaking ground on the Trenton Channel Energy Center, the region’s largest battery energy storage center. We also commissioned our largest solar park, Sauk, in lower mid-Michigan and broke ground on three other solar parks across the state. All of these projects help our company and the State of Michigan meet our clean energy goals and strengthen local economies with added tax revenue and job creation.

DTE Vantage contributed to our company's innovation and growth by launching renewable natural gas projects in Michigan, Ohio and New York. The team also expanded its partnership with Ford Motor Company and will build a custom energy-generating facility that will serve Ford’s new electric vehicle battery manufacturing operations in Michigan.

In 2024, our team members made exceptional progress improving our systems and positioning our company for continued growth and success. We are grateful for your partnership and investment in DTE and we look forward to working with you in 2025 as we continue to improve people's lives with our energy.
