    ITEM 1.01Entry into a Material Definitive Agreement.

     

    Reference is made to Note 4 – Short-term Debt and Liquidity to the financial statements under Part II, Item 8. Financial Statements and Supplementary Data of the Annual Report on Form 10-K for the year ended December 31, 2024, of registrants Ameren Corporation (“Ameren”), Union Electric Company, doing business as Ameren Missouri (“Ameren Missouri”) and Ameren Illinois Company, doing business as Ameren Illinois (“Ameren Illinois”) for a discussion of the 2022 Credit Agreements (as defined below).

     

    On December 10, 2025, Ameren and Ameren Missouri (together, the “Missouri Borrowers”), JPMorgan Chase Bank, N.A., as agent, and the lenders party thereto entered into a $1.9 billion multi-year, senior unsecured revolving Amended and Restated Credit Agreement (the “Amended Missouri Credit Agreement”) that amended and restated the $1.4 billion multi-year, senior unsecured revolving Amended and Restated Credit Agreement, dated as of December 6, 2022, among the parties thereto (the “2022 Missouri Credit Agreement”). Also on December 10, 2025, Ameren and Ameren Illinois (together, the “Illinois Borrowers”, and the Illinois Borrowers and the Missouri Borrowers, being, collectively, the “Borrowers”), JPMorgan Chase Bank, N.A., as agent, and the lenders party thereto entered into a $1.3 billion multi-year, senior unsecured revolving Amended and Restated Credit Agreement (the “Amended Illinois Credit Agreement” and together with the Amended Missouri Credit Agreement, the “Amended Credit Agreements”) that amended and restated the $1.2 billion multi-year, senior unsecured revolving Amended and Restated Credit Agreement, dated as of December 6, 2022, among the parties thereto (the “2022 Illinois Credit Agreement” and, together with the 2022 Missouri Credit Agreement, in each case, as amended effective April 19, 2023, and extended effective December 6, 2024 to mature on December 6, 2028, the “2022 Credit Agreements”). The Amended Credit Agreements provide $3.2 billion of credit cumulatively.

     

    The Amended Credit Agreements extended from December 6, 2028, to December 10, 2030, the maturity date of the commitments under each of the 2022 Credit Agreements. Similar to the 2022 Credit Agreements, the maturity date under each Amended Credit Agreement may be further extended for two additional one-year periods if so requested by the applicable Borrowers and agreed to by the requisite lenders (such maturity date, as it may be extended from time to time, the “Final Maturity Date”). The total facility size of the Amended Missouri Credit Agreement was increased from $1.4 billion to $1.9 billion, and the maximum borrowing limits for the Missouri Borrowers were increased from $1.0 billion to $1.6 billion for Ameren and from $1.0 billion to $1.6 billion for Ameren Missouri. The total facility size of the Amended Illinois Credit Agreement was increased from $1.2 billion to $1.3 billion, and the maximum borrowing limits for the Illinois Borrowers were increased from $700 million to $800 million for Ameren and from $1.0 billion to $1.1 billion for Ameren Illinois. Borrowings by Ameren will be due and payable no later than the Final Maturity Date, while borrowings by Ameren Missouri and Ameren Illinois will be due and payable no later than the earlier of the Final Maturity Date or 364 days after the date of such borrowing (subject to the right of each such Borrower to reborrow in accordance with the terms of the applicable Amended Credit Agreement).

     

    The maximum amount of letters of credit issuable under the Amended Credit Agreements was increased from $250 million, in aggregate, to $400 million, in aggregate, for the Missouri Borrowers, in the case of the Amended Missouri Credit Agreement, and remains unchanged at $275 million, in aggregate, for the Illinois Borrowers, in the case of the Amended Illinois Credit Agreement. At closing, the Borrowers under each of the Amended Credit Agreements had received commitments from lenders to issue letters of credit of up to $120 million, in aggregate, under each such Amended Credit Agreement. In addition, the $50 million swingline subfacility remains unchanged in each Amended Credit Agreement.

     

     

     

     

    The Amended Credit Agreements provide for revolving loan interest rates to be calculated, at the election of each Borrower, at either the Alternate Base Rate plus such Borrower’s Applicable Margin, the Term SOFR rate applicable to such interest period plus such Borrower’s Applicable Margin, or the Daily Simple SOFR rate plus such Borrower’s Applicable Margin (in each case as such terms are defined in their respective Amended Credit Agreement). The Applicable Margin will continue to be determined based on the particular Borrower’s senior long-term unsecured credit ratings from each of Moody’s and S&P. In addition, a commitment fee shall be payable quarterly on the aggregate commitments.

     

    The Amended Credit Agreements contain customary covenants and events of default, including restrictions from pledging assets and restrictions on certain asset sales. They also contain covenants that require (i) Ameren to maintain a consolidated debt ratio of 67.5% or less of its total capitalization and (ii) each of Ameren Illinois and Ameren Missouri to maintain a consolidated debt ratio of 65% or less of its total capitalization.

     

    Consistent with the 2022 Credit Agreements, neither Ameren nor Ameren Illinois shall be liable for or guarantee the obligations of the other under the Amended Illinois Credit Agreement and neither Ameren nor Ameren Missouri shall be liable for or guarantee the obligations of the other under the Amended Missouri Credit Agreement.

     

    The foregoing description of the Amended Credit Agreements is qualified in its entirety by reference to the full text of the Amended Credit Agreements, copies of which are filed as Exhibits 10.1 and 10.2 hereto and are incorporated by reference herein.

     

    ITEM 2.03Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

     

    The information set forth in Item 1.01 is hereby incorporated into this Item 2.03 by reference.
