REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Plan Participants and Plan Administrator of the Ameren Corporation Savings Investment Plan

St. Louis, Missouri

Opinion on the Financial Statements

We have audited the accompanying statements of net assets available for benefits of Ameren Corporation Savings Investment Plan (the “Plan”) as of December 31, 2018 and 2017, the related statements of changes in net assets available for benefits for the years then ended, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2018 and 2017, and the changes in net assets available for benefits for the years then ended, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on the Plan’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Plan in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Plan is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting in accordance with the standards of the PCAOB. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Plan’s internal control over financial reporting. Accordingly, we express no such opinion in accordance with the standards of the PCAOB.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Savings Investment Plan

Notes to Financial Statements

December 31, 2018 and 2017

  1. Description of the Plan

General

The following is a summary of the various provisions of the Ameren Corporation Savings Investment Plan (the “Plan”). Participants should refer to the Summary Plan Document for more complete information.

The Plan is a defined contribution plan. Its purpose is to provide employees eligible to participate (the “Participants”) of Ameren Corporation (the “Company”) and its wholly owned subsidiaries the opportunity to defer a portion of their compensation for federal income tax purposes in accordance with Section 401(k) of the Internal Revenue Code (the “Code”). The Plan is subject to certain provisions of the Employee Retirement Income Security Act of 1974 (“ERISA”), as amended, and regulations of the Securities and Exchange Commission.

The Company serves as sponsor of the Plan, and, consequently, has the authority to amend or terminate the Plan subject to certain restrictions. The Ameren Administrative Committee has the authority and responsibility for the general administration of the Plan. Fidelity Management Trust Company, as Trustee, has the authority and responsibility to hold and protect the assets of the Plan in accordance with Plan provisions and with the Trust and Administrative Agreement.

Participation

All regular full-time employees are eligible to participate upon employment, and part-time or temporary employees are eligible to participate upon completion of a year of service of at least 1,000 hours. Employees covered by a collective bargaining agreement (“CBA”) are eligible to participate only if the CBA provides for such participation.

If employees do not make an election, nor opt-out within 30 days of employment; they are automatically enrolled at a 6% pre-tax contribution rate, invested in a Target Date fund based upon the date at which the participant is or will be age 65, and further enrolled in auto-escalation increasing their pre-tax contribution 1% annually, with no cap on the annual increases. Employees may opt-out or make alternative elections at any time.

Contributions

Each year, Participants may contribute up to 100% of eligible compensation, as defined in the Plan, and subject to annual limitations imposed by the Code.

The Company makes an Employer Basic Matching Contribution plus an Employer Additional Matching Contribution in an amount equal to a percent of the amount each Participant contributes to the Plan, up to a certain maximum percentage of the Participant’s compensation that he or she elects to contribute to the Plan each year. The amount of Company matching contribution depends on the Participant’s employment classification, and for contract employees is determined by the collective bargaining agreement with the specific union representing the Participants. The Company also makes true-up Employer Basic Matching Contributions for Participants who contribute the IRS maximum before the end of the year and, as a result, do not receive the full company match. The Employer Additional Matching Contributions are invested in the Ameren Stock Fund.

Savings Investment Plan

Notes to Financial Statements

December 31, 2018 and 2017

The Plan permits “catch-up” contributions for all employees age 50 and older. Eligible employees could contribute $6,000 in 2018 and 2017, as a “catch-up” contribution. The Company does not match “catch-up” contributions.

Participants direct the investment of their contributions and the Employer Basic Matching Contributions to his or her account to any of the investment options available under the Plan, including Company stock. Contributions may be allocated to a single investment option or allocated in increments of one percent to any combination of investment options. Such elections may be changed daily. Although the Employer Additional Matching Contributions are invested in the Ameren Stock Fund, they may be immediately reallocated to other funds at the participants’ discretion.

Earnings derived from the assets of any investment fund are reinvested in the fund to which they relate. Participants may elect daily to reallocate, by actual dollar or percentage in one percent increments, the value of their accounts between funds. Pending investment of the assets into any investment fund, the Trustee may temporarily make certain short-term investments.

Participant Accounts

Each Participant’s account is credited with the Participant’s contributions and an allocation of (a) the Company’s contributions, and (b) Plan earnings, and is charged with an allocation of administrative expenses. Allocations are based on Participant contributions, eligible compensation, Participant account balances, or specific Participant transactions, as defined. The benefit to which the Participant is entitled is the benefit which can be provided from the Participant’s account. Each Participant directs the investment of his or her account to any of the investment options available under the Plan.

Notes Receivable from Participants

The Plan permits Participants to borrow from their accounts within the Plan. Such borrowings may be made subject to the following: (1) the minimum amount of the loan is $1,000, (2) the amount of the loan may not exceed the lesser of $50,000 or 50% of the vested amount in the Participant’s account, (3) the loan will bear a fixed interest rate and repayments will be made through mutual agreement subject to certain statutory repayment time limits, (4) each loan shall bear a reasonable interest rate as determined under policies established for the Plan and (5) such other rules and regulations as may be adopted by the Company. At December 31, 2018 and 2017, the interest rates on participant loans ranged from 4.00 percent to 10.50 percent.

Vesting

The amounts in Participants’ accounts, including Company contributions, are fully vested at all times.

Payment of Benefits

The total amount of a Participant’s account shall be distributed to the Participant according to one of the options as described in the Plan document and as elected by the Participant after termination of employment. All distributions shall be in the form of cash except that Participants may elect to have his or her interest in the Ameren Stock Fund distributed in shares of Ameren common stock. Participants may withdraw certain basic contributions, rollover contributions and related earnings thereon upon reaching age 59 1/2, in the event of total disability or financial hardship as defined

by the Plan or the Code. For purposes of distributions, the Participant’s account value will be determined as of the last business day coincident with or immediately preceding the day of distribution. Contributions to the Plan and investment income thereon are taxable to Participants upon distribution pursuant to the rules provided for under the Plan and the Code.

The Plan also allows, at the discretion of the Company, participants of the former Union Electric Company Employee Stock Ownership Plan and the former Ameren Corporation Employee Stock Ownership Plan for Certain Employees of AmerenCIPS, to receive certain distributions prior to termination of employment.

Plan Termination

The Company intends to continue the Plan indefinitely. However, the Company may at any time and for any reason, subject to ERISA and Internal Revenue Service regulations, suspend or terminate the Plan provided that such action does not retroactively adversely affect the rights of any Participant under the Plan.

  1. Summary of Significant Accounting Policies

Basis of Accounting

The accompanying financial statements of the Plan are prepared on the accrual basis of accounting, except that benefit payments to Participants are recorded upon distribution.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of changes in net assets available for benefits during the reporting period. Actual results could differ from those estimates.

Investment Valuation and Income Recognition

All investments are presented at fair value, except for fully benefit-responsive investment contracts, which are reported at contract value, as of December 31, 2018 and 2017. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. See Note 3 for discussion of fair value measurements.

The Plan has direct investments in fully benefit-responsive investment contracts. Investments held by a defined contribution plan are required to be reported at fair value, except for fully benefit-responsive investment contracts. Contract value is the relevant measurement attribute for the portion of the net assets available for benefits of a defined contribution plan attributable to fully benefit-responsive investment contracts because contract value is the amount Participants normally would receive if they were to initiate permitted transactions under the terms of the Plan. Contract value represents contributions made under each contract, plus earnings, less participant withdrawals and administrative expenses.

Purchases and sales of securities are recorded on a trade date basis. Interest income is recorded on the accrual basis. Dividend income is recorded on the ex-dividend date. Net appreciation (depreciation) in fair value of investments includes the Plan’s gains and losses on investments bought and sold as well as held during the year.

Savings Investment Plan

Notes to Financial Statements

December 31, 2018 and 2017

Notes Receivable from Participants

Notes receivable from Participants are measured at their unpaid principal balance plus any accrued but unpaid interest, with no allowance for credit losses, as repayments of principal and interest are received through payroll deductions and the notes are collateralized by the Participants’ account balances. Delinquent participant loans are reclassified as distributions based upon the terms of the Plan document.

Administrative Expenses

Fees associated with administering the Plan are generally paid by the Plan. Trustee and recordkeeping fees are primarily paid via (1) flat dollar fees that are assessed to all Participants quarterly, and (2) fees accrued in investment funds that are separately-managed accounts (versus commingled funds). Also, revenue sharing payments that Fidelity receives from mutual funds are allocated to Participant accounts quarterly.

Risks and Uncertainties

Investments are exposed to various risks, such as interest rate, market and credit. Due to the level of risk associated with certain investments and the level of uncertainty related to changes in the value of investments, it is at least reasonably possible that changes in risks in the near term could materially affect the Participants’ account balances and the amounts reported in the Statement of Net Assets Available for Benefits.

Concentrations

Company common stock comprised 13% and 12% of investments at December 31, 2018 and December 31, 2017, respectively.

  1. Fair Value Measurements

The authoritative guidance issued by the FASB regarding fair value measurement provides a framework for measuring fair value for all assets and liabilities that are measured and reported at fair value. The guidance defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Certain assumptions that market participants would use in pricing the asset or liability, including assumptions about risk or the risks inherent in the inputs to the valuation, were used in the valuation process. Inputs to valuation can be readily observable, market corroborated, or unobservable. Valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs were used. The provisions also establish a fair value hierarchy that prioritizes the inputs used to measure fair value. All financial assets and liabilities carried at fair value were classified in one of the following three hierarchy levels:

Level 1: Inputs based on quoted prices in active markets for identical assets or liabilities that the Plan has the ability to access at the reporting date.

8

Table of Contents

Ameren Corporation

Savings Investment Plan

Notes to Financial Statements

December 31, 2018 and 2017

Level 2: Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Inputs to the valuation methodology include:

• Quoted prices for similar assets or liabilities in active markets;

• Quoted prices for identical or similar assets or liabilities in inactive markets;

• Inputs other than quoted prices that are observable for the asset or liability;

• Inputs that are derived principally from or corroborated by observable market data by correlation or other means.

Level 3: Inputs to the valuation methodology that are unobservable and significant to the fair value measurement.

The Plan does not hold any investments requiring Level 3 measurements, and there have not been any transfers between measurement input levels in 2018 or 2017.

The asset or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

Following is a description of the valuation methodologies used for assets measured at fair value.

There have been no changes in the methodologies used during 2018.

• Margin deposit account: The fair value is estimated to approximate deposit account balances, payable on demand, as no discounts for credit quality or liquidity were determined to be applicable (Level 2 inputs).

• Common stocks: Valued at the closing price reported on the active markets on which the individual securities are traded (Level 1 inputs).

• U.S. government securities and corporate debt securities: Valued based upon recent bid prices or the average of recent bid and asked prices when available (Level 2 inputs) and, if not available, they are valued through matrix pricing models developed by sources considered by management to be reliable. Matrix pricing, which is a mathematical technique commonly used to price debt securities that are not actively traded, values debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs).

• Other debt securities includes non-U.S. government debt securities, municipal securities, mortgage and asset-backed securities, and derivatives: Non-U.S. government debt securities, municipal securities, and mortgage and asset-backed securities are valued based upon recent bid prices or the average of recent bid and asked prices when available (Level 2 inputs) and, if not available, they are valued through matrix pricing models developed by sources considered by management to be reliable. Matrix pricing, which is a mathematical technique commonly used to price debt securities that are not actively traded, values debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs). The fair values of exchange-traded derivatives are based upon quoted market prices (Level 1 inputs). The fair values of derivatives that are not traded on an exchange are based upon valuation models using observable market data as of the measurement date (Level 2 inputs).

• Mutual funds: Valued at the daily closing price as reported by the fund (Level 1 inputs). Mutual funds held by the Plan are open-end mutual funds that are registered with the Securities and Exchange Commission. These funds are required to publish their daily net asset value (NAV) and to transact at that price. The mutual funds held by the Plan are deemed to be actively traded.

• Collective trust funds: The fair values of participation units held in collective trusts are based on the NAV reported by the fund managers as of the financial statement dates and recent transaction prices. Under ordinary market conditions, redemptions of investments in collective trusts are permitted as of daily or monthly valuation dates, as applicable, and are executed at NAV as a practical expedient.

The following table sets forth, by level within the fair value hierarchy, Plan assets measured at fair value on a recurring basis as of December 31, 2018:

(a) In accordance with ASU 2015-07, certain investments measured at NAV per share (or its equivalent) as a practical expedient have not been classified in the fair value hierarchy. The fair value amount measured at NAV presented in this table is intended to permit reconciliation of the fair value hierarchy to the investments at fair value presented in the statement of net assets available for benefits.

  1. Fully Benefit-Responsive Investment Contracts

The Plan holds investments in a separately-managed stable value account that is managed by Galliard Capital Management. The separately-managed account holds (1) an investment in the Wells Fargo/BlackRock Short Term Investment Fund, and (2) a portfolio of synthetic investment contracts, valued at $282,384,897 at December 31, 2018. The separately-managed account held (1) an investment in the Fidelity Institutional Money Market Government Portfolio, and (2) a portfolio of synthetic investment contracts, valued at $281,815,710 at December 31, 2017. The investment contracts meet the fully benefit-responsive investment criteria and therefore are reported at contract value. Contract value is the relevant measure for fully benefit-responsive investment contracts because this is the amount received by Participants if they were to initiate permitted transactions under the terms of the Plan. Contract value represents contributions made under each contract, plus earnings, less participant withdrawals and administrative expenses.

The investment contracts are issued by the following insurance companies:

• American General Life Insurance Company (“AGL”)

• Prudential Insurance Company of America (“Prudential”)

• Voya Retirement Insurance and Annuity Company (“Voya”)

• Massachusetts Mutual Life Insurance Company (“Mass Mutual”)

• Metropolitan Life Insurance Company (“Met Life”)

11

Table of Contents

Ameren Corporation

Savings Investment Plan

Notes to Financial Statements

December 31, 2018 and 2017

The underlying investments of the AGL, Mass Mutual, Prudential, and Voya contracts are holdings in collective trust funds. The underlying investments of Met Life contracts are holdings in portfolios of fixed income securities, which are segregated from the insurance company’s general account assets. The segregation of these assets from the insurance company’s general account offers certain protections to mitigate the risk that these assets might be subject to creditor claims other than those of the separate account guaranteed investment contract owners.

The investment contracts include wrapper contracts, which are agreements for the wrap issuer to make payments to the Plan in certain circumstances. The wrapper contract typically includes certain conditions and limitations on the underlying assets owned by the Plan. The contracts are designed to accrue interest based on crediting rates established by the contract issuers, and also provide a guarantee that the credit rate will not fall below zero percent. Cash flow volatility (for example, timing of benefit payments) as well as asset underperformance can be passed through to the Plan through adjustments to future contract crediting rates. Formulas are provided in each contract that adjusts renewal crediting rates to recognize the difference between the fair value and the book value of the underlying assets. Crediting rates are reset at least quarterly.

The Plan’s ability to receive amounts due in accordance with fully benefit-responsive investment contracts is dependent on the third-party issuer’s ability to meet its financial obligations. The issuer’s ability to meet its contractual obligations may be affected by future economic and regulatory developments.

Certain events might limit the ability of the Plan to transact at contract value. Investment contracts generally provide for withdrawals associated with certain events which are not in the ordinary course of operations. These withdrawals are paid with a market value adjustment applied to the withdrawal as defined in the investment contract. Each contract issuer specifies the events which may trigger a market value adjustment; however, such events may include all or a portion of the following:

• material amendments to the account’s structure or administration;

• changes to the Plan’s competing investment options including the elimination of equity wash provisions;

• complete or partial termination of the investment, including a merger with another investment account;

• the failure of the Plan to qualify for exemption from federal income taxes or any required prohibited transaction exemption under ERISA;

• the redemption of all or a portion of the interests in the account held by a participating plan at the direction of the participating plan sponsor, including withdrawals due to the removal of a specifically identifiable group of employees from coverage under the participating plan (such as a group layoff or early retirement incentive program), the closing or sale of a subsidiary, employing unit, or affiliate, the bankruptcy or insolvency of a plan sponsor, the merger of the Plan with another plan, or the Plan sponsor’s establishment of another tax qualified defined contribution plan;

• the addition of an Asset Allocation or Managed Account service without prior approval, or a material change in an existing program;

• the distribution of a prohibited communication.

No events are probable of occurring that might limit the ability of the Plan to transact at contract value with the contract issuers and that also would limit the ability of the Plan to transact at contract value with the Participants.

These contracts are evergreen contracts and contain termination provisions, allowing the contract issuer to terminate with notice, at any time at fair value, and providing for automatic termination of the contract if the contract value or the fair value of the underlying portfolio equals zero. The issuer is obligated to pay the excess contract value when the fair value is below contract value at the time of termination. In addition, if the Plan defaults in its obligations under the contract (including the issuer’s determination that the agreement constitutes a non-exempt prohibited transaction as defined under ERISA), and such default is not corrected within the time permitted by the contract, then the contract may be terminated by the issuer and the Plan will receive the fair value as of the date of termination.

  1. Transactions with Parties-in-Interest

Parties-in-interest are defined under Department of Labor regulations as any fiduciary of the Plan, any party rendering service to the Plan, the employer, and certain others.

At December 31, 2018, the Plan held 4,654,433 shares of Company common stock with a cost and fair value of $201,110,751 and $303,608,665, respectively. During 2018, the Plan purchased 785,010 shares at a cost of $45,870,778 and sold 931,272 shares valued at $55,517,075.

At December 31, 2017, the Plan held 4,800,695 shares of Company common stock with a cost and fair value of $194,108,887 and $283,192,998, respectively. During 2017, the Plan purchased 734,900 shares at a cost of $41,768,247 and sold 1,058,963 shares valued at $59,847,989.

Dividend income from Company common stock was $8,728,952 and $8,650,773 for the years ended December 31, 2018 and December 31, 2017, respectively.

At December 31, 2018 and December 31, 2017, the Plan held shares in the Fidelity Institutional Money Market Government Portfolio. This portfolio is managed by the Trustee, and therefore, qualifies as party-in-interest transactions. Notes receivable from Participants also reflect party-in-interest transactions.

Fees paid by the Plan to the Trustee for recordkeeping, trust services, and advisory services were $1,085,431 and $908,576 for the years ended December 31, 2018 and December 31, 2017, respectively.

Fees paid to and investments issued by various Plan investment managers also reflect party-in-interest transactions.

These transactions are allowable party-in-interest transactions under Section 408(b)(8) of ERISA.

  1. Federal Income Tax Status

The Company obtained a determination letter dated January 12, 2018, in which the Internal Revenue Service stated that the Plan was in compliance with the applicable requirements of the Code. Although the Plan has been amended since receiving this determination letter, the Plan’s administrator believes that the Plan is designed and is currently being operated in compliance with the applicable requirements of the Code.

Accounting principles generally accepted in the United States of America require Plan management to evaluate tax positions taken by the Plan and recognize a tax liability (or asset) if the Plan has taken an uncertain position that more likely than not would not be sustained upon examination by the Internal Revenue Service. The Plan administrator has analyzed the tax positions taken by the Plan, and has concluded that as of December 31, 2018 and 2017, there are no uncertain positions taken or expected to be taken that would require recognition of a liability (or asset) or disclosure in the financial statements. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress. The Plan administrator believes it is no longer subject to income tax examinations for years prior to 2015.
