AMEREN CORP 8-K Report, Corporate Update (Dec 18, 2023)

Filed December 18, 2023For Securities:AEE

Summary

Ameren Corporation (AEE) and its subsidiary Ameren Illinois Company have filed an 8-K to report on a recent Illinois Commerce Commission (ICC) order regarding Ameren Illinois' multi-year electric distribution service rate plan (MYRP) and integrated grid plan (Grid Plan). The ICC's order, issued on December 14, 2023, approves base rates for electric distribution services for 2024-2027, but notably rejects the proposed Grid Plan. The Grid Plan was intended to outline investments in grid modernization and clean energy initiatives. Ameren Illinois is required to file a revised Grid Plan within three months. While the Grid Plan was rejected, the ICC adopted an alternative methodology for establishing rate base and revenue requirements. This methodology results in a cumulative revenue increase of $142 million (adjusted for an error) for Ameren Illinois from 2024-2027, which is significantly lower than the $444 million requested by the company. The approved return on equity is 8.72% with a 50% common equity percentage, and the rate base is based on the 2022 year-end rate base of $3.872 billion, which will continue through 2027 unless a revised Grid Plan is approved. The company may seek rehearing or appeal aspects of the order and is evaluating the potential impact of the Grid Plan rejection on its capital expenditure and operational plans.
