ITEM 8.01 Other Events.

Reference is made to Outlook under Part I, Item 2, Management’s Discussion and Analysis of Financial Condition and Results of Operations in the Quarterly Report on Form10-Q for the quarterly period ended March 31, 2019, and to Rates and Regulation under Part I, Item 1, Business; Overview and Outlook under Part II, Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations; and Note 2 – Rate and Regulatory Matters to our financial statements under Part II, Item 8, Financial Statements and Supplementary Data, each in the Annual Report on Form10-K for the year ended December 31, 2018 (“2018 Form10-K”) of registrants Ameren Corporation (“Ameren”) and Union Electric Company, doing business as Ameren Missouri (“Ameren Missouri”), for a discussion of the rate orders issued by the Missouri Public Service Commission (“MoPSC”) in March 2017 and July 2018, as well as Ameren Missouri’s intention to file a request for an electric service regulatory rate review with the MoPSC in 2019.

On July 3, 2019, Ameren Missouri filed a request with the MoPSC seeking approval to decrease its annual revenues for electric service by $1 million. Ameren Missouri’s base rates for electric service, which were last reset on April 1, 2017, and adjusted by the July 2018 MoPSC order, are required to be reset at least every four years to allow for continued use of the fuel adjustment clause (“FAC”). This filing, which includes a request for continued use of the FAC, allows Ameren Missouri to meet that requirement while also providing flexibility to time its next regulatory rate review to include wind generation investments expected to be made in late 2020.

The rate request is based on a 9.95% return on common equity, an estimated capital structure composed of 51.9% common equity, an estimated electric rate base of $8.0 billion, and a test year ended December 31, 2018, with certainpro-forma adjustments expected through an anticipatedtrue-up date of December 31, 2019.Pro-forma adjustments are also expected for fuel, transportation, Midwest Independent System Operator, Inc. (“MISO”) multi-value transmission project expenses, and payroll costs through an anticipatedtrue-up date of January 1, 2020.

The electric rate decrease request reflects:

• decreased net energy costs of approximately $100 million otherwise subject to FAC recovery;

• higher weather-normalized customer sales volumes, which reduced the rate request by approximately $55 million;

• decreased expenses, other than net energy costs, of approximately $20 million, which includes a decrease to those expenses subject to regulatory recovery mechanisms of approximately $80 million;

• increased depreciation and amortization expense of $115 million for new electric infrastructure investments, of which approximately $35 million reflects higher depreciation rates and of which approximately $35 million would otherwise be deferred under plant-in-service accounting (“PISA”); and

• an increase of approximately $60 million of pre-tax return on rate base, which includes both the debt and equity components, of which approximately $30 million would otherwise be deferred under PISA.

Ameren Missouri also requested continued use of the regulatory recovery mechanisms for pension and postretirement benefits, uncertain income tax positions and certain excess deferred taxes that the MoPSC previously authorized in earlier electric rate orders.

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 in such proceeding expected by late April 2020 and new rates effective in late May 2020. Ameren Missouri cannot predict the level of any electric service rate change the MoPSC may approve, when any rate change may go into effect, whether the requested regulatory recovery mechanisms will be approved, 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 the rate change goes into effect.

Forward-Looking Statements

Statements in this report not based on historical facts are considered “forward-looking” and, accordingly, involve risks and uncertainties that could cause actual results to differ materially from those discussed.

The following factors, in addition to those discussed under Risk Factors in the 2018 Form10-K, and elsewhere in this report and in our other filings with the Securities and Exchange Commission, could cause actual results to differ materially from management expectations suggested in such forward-looking statements:

2

• regulatory, judicial, or legislative actions, and any changes in regulatory policies and ratemaking determinations, such as those that may result from Ameren Missouri’s natural gas regulatory rate review filed with the MoPSC in December 2018, an appeal filed by the Missouri Office of Public Counsel in January 2019 in Ameren Missouri’s renewable energy standard rate adjustment mechanism case, and future regulatory, judicial, or legislative actions that change regulatory recovery mechanisms;

• the effect of Missouri Senate Bill 564 on Ameren Missouri, including as a result of Ameren Missouri’s election to use PISA and the resulting customer rate caps;

• the effects of changes in federal, state, or local laws and other governmental actions, including monetary, fiscal, and energy policies;

• the effects on demand for our services resulting from technological advances, including advances in customer energy efficiency, energy storage, and private generation sources, which generate electricity at the site of consumption and are becoming more cost-competitive;

• the effectiveness of Ameren Missouri’s customer energy-efficiency programs and the related revenues and performance incentives earned under its Missouri Energy Efficiency Investment Act programs;

• our ability to align overall spending, both operating and capital, with frameworks established by our regulators and to recover these costs in a timely manner in our attempt to earn our allowed returns on equity;

• the cost and availability of fuel, such asultra-low-sulfur coal, natural gas, and enriched uranium used to produce electricity; the cost and availability of purchased power and renewable energy credits; and the level and volatility of future market prices for such commodities and credits, including our ability to recover the costs for such commodities and credits and our customers’ tolerance for any related price increases;

• disruptions in the delivery of fuel, failure of our fuel suppliers to provide adequate quantities or quality of fuel, or lack of adequate inventories of fuel, including nuclear fuel assemblies from the one Nuclear Regulatory Commission-licensed supplier of Ameren Missouri’s Callaway energy center’s assemblies;

• the cost and availability of transmission capacity for the energy generated by Ameren Missouri’s energy centers or required to satisfy Ameren Missouri’s energy sales;

• the effectiveness of our risk management strategies and our use of financial and derivative instruments;

• the ability to obtain sufficient insurance, including insurance for Ameren Missouri’s Callaway energy center, or, in the absence of insurance, the ability to recover uninsured losses from our customers;

3

• the impact of current environmental laws and new, more stringent, or changing requirements, including those related to carbon dioxide and the Affordable Clean Energy Rule, other emissions and discharges, cooling water intake structures, coal combustion residuals, and energy efficiency, that could limit or terminate the operation of certain of Ameren Missouri’s energy centers, increase our operating costs or investment requirements, result in an impairment of our assets, cause us to sell our assets, reduce our customers’ demand for electricity or natural gas, or otherwise have a negative financial effect;

• the impact of complying with renewable energy requirements in Missouri;

• labor disputes, work force reductions, changes in future wage and employee benefits costs, including those resulting from changes in discount rates, mortality tables, returns on benefit plan assets, and other assumptions;

• the impact of negative opinions of us or our utility services that our customers, legislators, or regulators may have or develop, which could result from a variety of factors, including failures in system reliability, failure to implement our investment plans or to protect sensitive customer information, increases in rates, or negative media coverage;
