Cost of gas — utility expense decreased $12 million and increased $65 million in the three and nine months ended September 30, 2025, respectively.  The decrease in the third quarter was primarily due to lower cost of gas of $13 million partially offset by higher sales volumes of $1 million.  The increase in the nine-month period was primarily due to higher sales volumes of $58 million and higher cost of gas of $7 million.

Operation and maintenance expense increased $17 million and $58 million in the three and nine months ended September 30, 2025, respectively.  The increase in the third quarter was primarily due to higher gas operations expense of $16 million.  The increase in the nine-month period was primarily due to higher gas operations expense of $40 million, higher benefits and other compensation expense of $6 million, higher EWR expense of $6 million, higher legal expense of $5 million, higher corporate support costs of $5 million, and higher uncollectible expense of $2 million, partially offset by one-time costs in 2024 of $8 million resulting from the voluntary separation incentive program.

Taxes other than income increased $2 million and $8 million in the three and nine months ended September 30, 2025, respectively.  The increase in both periods was primarily due to higher property taxes.
