(a)Change is primarily driven by the impact of solar ITCs recognized for assets placed in service in first quarter 2025, which is offset in Income Tax Expense (Benefit) throughout 2025.

(b)Includes MPSC disallowance of $28 million resulting from an order in DTE Electric's 2022 PSCR reconciliation case.  The disallowance reduced the amount of power supply costs recoverable from customers, which had a flow-through impact of approximately $5 million higher interest expense recorded separately to Other (Income) and Deductions.

Revenue results are impacted by changes in sales volumes, which are summarized in the table below:

Operation and maintenance expense decreased $39 million in the three months ended March 31, 2025.  The decrease was primarily due to one-time costs in 2024 of $31 million resulting from the voluntary separation incentive program and lower distribution operations expense of $16 million (primarily due to lower storm restoration costs), partially offset by higher benefits and other compensation expense of $6 million.
