AMEREN CORP 8-K Report, Corporate Update (Dec 14, 2021)

Filed December 14, 2021For Securities:AEE

Summary

Ameren Corporation (AEE) has announced its decision not to appeal court rulings related to environmental compliance at its Rush Island Energy Center. Instead, the company intends to seek a modification from the District Court to accelerate the retirement of the Rush Island facility, aiming for retirement by the original compliance deadline. This decision follows the denial of reconsideration requests by both Ameren Missouri and the Department of Justice regarding a previous court of appeals ruling. The accelerated retirement of the Rush Island Energy Center, which had a net plant balance of approximately $0.6 billion as of September 30, 2021, will be financed through securitized utility tariff bonds, subject to Missouri Public Service Commission approval. Furthermore, Ameren Missouri plans to file an updated Integrated Resource Plan in early 2022 to reflect this accelerated retirement, a significant shift from its previously scheduled retirement in 2039. The company is unable to predict the ultimate resolution of these matters, and investors should be aware of the potential impacts of regulatory, judicial, and legislative actions, as well as economic and environmental factors, on future results.
