In May 2025, Ameren Missouri filed a request with the MoPSC to modify its existing large primary service tariff to require customers requesting 100 MW or more of demand and who are served at transmission level voltage to comply with additional tariff terms. The additional terms include a minimum service term of 15 years, minimum demand charges of 70 % of contracted capacity, customer exit terms and fees, and customer credit and collateral requirements, among other terms. In addition, new customer programs would be available under this tariff, which allows customers to support renewable generation, battery storage, or nuclear generation through incremental payments. A decision by the MoPSC is expected by February 2026.

In relation to the NSR and Clean Air Act litigation discussed in Note 14 - Commitments and Contingencies, Ameren Missouri retired the Rush Island Energy Center on October 15, 2024. In June 2024, the MoPSC issued a financing order authorizing the issuance of securitized utility tariff bonds by AMF to finance costs related to the accelerated retirement of the Rush Island Energy Center.

See Variable Interest Entities below, Note 2 - Rate and Regulatory Matters, and Note 5 - Long-term Debt and Equity Financings for additional information on Ameren Missouri's securitization of the Rush Island Energy Center's costs. As of December 31, 2023, Ameren and Ameren Missouri determined that the Rush Island Energy Center met the criteria to be considered probable of abandonment and classified its remaining net book value as plant to be abandoned, net, within “Property, Plant, and Equipment, Net” on Ameren’s and Ameren Missouri’s balance sheets.

Illinois law currently requires Ameren Illinois to offer rebates and net metering to certain customers who install renewable generation. The cost of the customer generation rebate program is deferred as a regulatory asset, which earns a return at the applicable WACC, with the ROE based on the annual average of the monthly average yields of the 30-year United States Treasury bonds plus 580 basis points through 2026. Pursuant to the CRGA, standalone energy storage systems will also be eligible for rebates, and the return on the deferred regulatory asset will be equal to the most recently approved ROE for Ameren Illinois electric distribution, beginning in January 2027. The eligibility of standalone energy storage systems for rebates is subject to ICC approval, with the tariff filing due in the second half of 2026. Ameren Illinois expects a decision on the tariff filing by the end of 2026. By law, Ameren Illinois’ electric distribution revenues are decoupled from sales volumes, which ensures that the electric distribution revenues authorized in a regulatory rate review are not affected by changes in sales volumes.

AMF was formed in 2024, for the purpose of issuing and servicing securitized utility tariff bonds related to costs for the accelerated retirement of the Rush Island Energy Center. Ameren Missouri is the primary beneficiary of this entity because it has the power to direct the activities that most significantly impact the economic performance of the company, as well as the obligation to absorb losses or the right to receive benefits from the company. The entity is considered a variable interest entity primarily because its equity capitalization is insufficient to support its operations. The entity’s primary assets and liabilities are comprised of regulatory assets related to the unrecovered net plant balance associated with the facility, among other costs, and long-term debt. Ameren and Ameren Missouri consolidate AMF, which Ameren Missouri wholly owns, and both manages and controls the entity’s operating activities. For additional information on the securitization of the Rush Island Energy Center costs, see Note 2 - Rate and Regulatory Matters. For additional information on the securitized tariff bond issuance, see Note 5 - Long-term Debt and Equity Financings.

When it becomes probable an asset will be retired significantly in advance of its previously expected useful life and in the near term, the Ameren Companies must assess the probability of recovery of the remaining net book value of the asset to be abandoned. We recognize a loss on abandonment when it becomes probable that all or part of the cost of an asset, including a return at the applicable WACC, will be disallowed from recovery either through customer rates or through the issuance of securitized utility tariff bonds and such amount is reasonably estimable.

Ameren Missouri is a member of the MISO, and its transmission rate is calculated in accordance with the MISO Open Access Transmission, Energy, and Operating Reserve Markets Tariff. The FERC regulates the rates charged and the terms and conditions for wholesale electric transmission service. The transmission rate update each June is based on Ameren Missouri’s actual historical cost from the prior calendar year. This rate is not directly charged to Missouri retail customers because, in Missouri, the revenue requirement used to set bundled retail base rates includes an amount for transmission-related costs and revenues.

Since November 2013, the allowed base ROE for FERC-regulated transmission rate base under the MISO tariff has been subject to customer complaint cases and has been changed by various FERC orders. In October 2024, the FERC issued an order, which decreased the allowed base ROE from 10.02 % to 9.98 % and required refunds, with interest, for the periods from November 2013 to February 2015 and from late September 2016 forward. In June 2026, the United States Court of Appeals for the District of Columbia Circuit dismissed and denied various appeals of the October 2024 FERC order.
