Item 1.01. Entry into a Material Definitive Agreement

On October 28, 2025, the Board of Directors of DTE Energy Company (“DTE Energy”) approved

execution of a Primary Supply Agreement (“PSA”) and an Energy Storage Agreement (“ESA”) between

DTE Energy’s wholly-owned subsidiary DTE Electric Company (“DTE Electric”) and Green Chile

Ventures LLC (“Customer”) a wholly owned subsidiary of Oracle Corporation.

Under the terms of the PSA, DTE Electric will provide approximately 1.4 gigawatts of electric service to

Customer’s future data center to be located in southeast Michigan (“Project”). The term of the PSA will

run through February 2045, with options to extend the term. The electric service will ramp over time,

expecting to achieve full delivery in December 2027. The PSA also establishes minimum monthly charges

and, if applicable, termination fees if the PSA terminates early.

Under the terms of the ESA, DTE Electric will, at Customer’s cost, build and operate approximately 1.4

gigawatts of energy storage capacity to support its electric service to the Project. DTE Electric will

operate each energy storage facility for a period of 15 years, with options to extend upon mutual

agreement of Customer and DTE Electric. Customer's parent is providing credit support to DTE Electric

for both the PSA and ESA.

The foregoing description of the PSA and the ESA does not purport to be complete and is qualified in its

entirety by reference to the full text of the PSA and the ESA, copies of which will be filed with DTE

Energy’s Annual Report on Form 10-K for the year ending December 31, 2025.
