On June 26, 2026, Union Electric Company, doing business as Ameren Missouri (“Ameren Missouri”), filed a request with the Missouri Public Service Commission (“MoPSC”) seeking approval to increase its annual revenues for electric service by $343 million. The electric rate request is based on a 10.25% return on common equity, a capital structure composed of 52% common equity, a rate base of $16.7 billion, and a test year ended March 31, 2026, with certain pro-forma adjustments expected through an anticipated true-up date of December 31, 2026. Ameren Missouri also requested continued use of the fuel adjustment clause and trackers, including trackers for pension and postretirement benefits, certain excess deferred income taxes, and the utilization of production and investment tax credits or proceeds from the sale of tax credits, which the MoPSC previously authorized in earlier electric rate orders. The electric rate request reflects the following:
| · | increased transmission and distribution infrastructure investments to ensure system reliability and resiliency; |
| · | investments in existing generation resources and 400 megawatts of new generation resources; and |
| · | decreased costs related to accelerating the return to customers of investment tax credits. |
The MoPSC proceeding relating to the proposed electric service rate changes will take place over a period of up to 11 months, with a decision by the MoPSC expected by May 2027 and new rates effective by June 2027. Ameren Missouri cannot predict the level of any electric service rate change the MoPSC may approve, whether the requested regulatory recovery mechanisms will be continued, or whether any rate change that may eventually be approved will be sufficient for Ameren Missouri to recover its costs and earn a reasonable return on its investments when any rate change goes into effect.
This combined Form 8-K is being filed separately by Ameren Corporation and Union Electric Company (each a “registrant”). Information contained herein relating to any individual registrant has been filed by such registrant on its own behalf. No registrant makes any representation as to information relating to any other registrant.
