Regulatory Matters	REGULATORY MATTERS 2022 Electric PSCR Reconciliation In March 2023, DTE Electric filed its 2022 PSCR Reconciliation that included the under-recovery of approximately $421 million of power supply costs incurred under reasonable and prudent policies and practices. The request was subsequently reduced to $416 million. On February 27, 2025, the MPSC issued an order approving recovery of $387 million of these costs resulting in a disallowance of approximately $33 million, inclusive of interest. The disallowance was included in Operating Revenues – Utility operations and Interest expense on the Consolidated Statements of Operation in the first quarter of 2025. 2025 Electric Rate Case Filing DTE Electric filed a rate case with the MPSC on April 24, 2025 requesting an increase in base rates of $574 million based on a projected twelve-month period ending December 31, 2026, and an increase in return on equity from 9.9% to 10.75%. The requested increase in base rates was primarily due to capital investments required to support continued reliability improvements and the ongoing transition to cleaner energy. A final MPSC order in this case is expected in February 2026.
