In April 2025, Ameren Illinois filed for a reconciliation adjustment to its 2024 electric distribution service revenue requirement with the ICC. In September 2025, Ameren Illinois filed a revised reconciliation adjustment, requesting recovery of $60 million. The adjustment reflects Ameren Illinois’ actual 2024 recoverable costs, 2024 year-end rate base, and a capital structure composed of 50% common equity. In September 2025, the ICC staff submitted its calculation of the reconciliation adjustment, recommending recovery of $47 million. The ICC staff’s recommendation excluded an asset associated with other postretirement benefits from the rate base. An ICC decision in this proceeding is required by December 2025, and any approved adjustment would be collected from customers in 2026.

In January 2025, Ameren Illinois filed a request with the ICC seeking approval to increase its annual revenues for natural gas delivery service. In July 2025, Ameren Illinois filed a revised request seeking to increase its annual revenues by $135 million. The request is based on a 10.7% ROE, a capital structure composed of 52% common equity, and a rate base of $3.3 billion. Ameren Illinois used a 2026 future test year in this proceeding. In August 2025, the ICC staff filed a revised recommendation to increase Ameren Illinois’ annual revenues for natural gas delivery service by $104 million. The recommendation is based on a 9.93% ROE, a capital structure composed of 50% common equity, and a rate base of $3.2 billion. In addition, in August 2025, the Illinois Attorney General's office recommended an increase to annual revenues for natural gas delivery service of $55 million, based on a 9.45% ROE, a capital structure composed of 50% common equity, and a rate base of $3.0 billion. In October 2025, the administrative law judge issued a proposed order for an increase to annual revenues of $91 million. The order was consistent with the ICC staff’s recommendation with the exception of the exclusion of the non-service cost component of the net periodic benefit income related to other postretirement benefits in the annual revenue requirement. A decision by the ICC in this proceeding is required by early December 2025, with new rates expected to be effective in early December 2025.
