 compared with the year-ago periods. “Cost recovery mechanisms – offset in natural gas purchased for resale” increased revenues $15 million for the nine months ended September 30, 2025, due to a higher collection of natural gas costs previously deferred under the PGA. Changes in natural gas revenues under the PGA are fully offset by changes in natural gas purchased for resale expenses. Revenues increased $7 million for the nine months ended September 30, 2025 due to a change in the timing of revenues recognized under the VBA. Revenues are decoupled from actual sales volumes for residential and small nonresidential customers, and the change in the timing of revenues is not expected to materially impact full-year results.
