Ameren Illinois Natural Gas

Ameren Illinois Natural Gas’ revenues increased $10 million, or 7%, and $30 million, or 6%, for the three and six months ended June 30, 2025, respectively, compared with the year-ago periods. “Cost recovery mechanisms – offset in natural gas purchased for resale” increased revenues $6 million and $22 million for the three and six months ended June 30, 2025, respectively, due to a higher collection of natural gas costs previously deferred under the PGA. The increase in natural gas revenues under the PGA are fully offset by an increase in natural gas purchased for resale expenses. Revenues increased $6 million for the three and six months ended June 30, 2025, related 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.
