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

On January 5, 2026, A. O. Smith Corporation (the “Company”) entered into a Credit Agreement (the “Credit Agreement”) among the Company, the various lenders party thereto, and Bank of America, N.A., as administrative agent (the “Agent”). The Credit Agreement provided for an unsecured term loan in the amount of $470 million that matures on January 5, 2029. The Company borrowed the full available amount under the Credit Agreement on January 5, 2026 and used the proceeds to finance the purchase price for the Company’s acquisition of LVC Holdco LLC (“Leonard Valve”) and associated fees and expenses on January 6, 2026. The term loan can be prepaid in whole or in part without penalty.

The term loan under the Credit Agreement bears interest at a variable rate per annum equal to, at the Company’s election: (i) Term SOFR (the forward-looking secured overnight financing rate) plus an applicable margin ranging from 0.875% to 1.375%; or (ii) the Base Rate (which is the highest of (x) the Agent’s prime rate, (y) the federal funds rate plus 0.50% or (z) the sum of 1.00% plus one-month Term SOFR) plus an applicable margin ranging from 0% to 0.375%. The applicable margin in each case varies depending on the Company’s leverage ratio.

The Credit Agreement contains various customary restrictions and covenants, including a requirement that the Company maintain a leverage ratio and an interest coverage ratio at certain levels (as detailed below); restrictions on the ability of the Company and certain of its subsidiaries to consolidate or merge, create liens, and incur additional subsidiary indebtedness; and a restriction on the disposition of all or substantially all of the assets of the Company and its subsidiaries taken as a whole.

The Credit Agreement requires the Company to maintain: (i) a maximum leverage ratio (defined as the ratio of the Company’s consolidated funded net debt to the sum of the Company’s consolidated funded net debt plus consolidated net worth) as of the last day of any fiscal quarter of 0.60, subject to the Company’s right to temporarily increase the maximum leverage ratio to up to 0.65 in connection with certain material acquisitions; and (ii) a minimum interest coverage ratio (defined as, with certain adjustments, the ratio of the Company’s consolidated net income before interest, taxes, depreciation, amortization and certain other items to the Company’s consolidated cash interest charges) as of the last day of any fiscal quarter of 3.00 to 1.00.

The Credit Agreement also contains customary events of default. If an event of default under the Credit Agreement occurs and is continuing, then the lenders may declare any outstanding obligations under the Credit Agreement to be immediately due and payable. In addition, upon the occurrence of an actual or deemed entry of an order for relief with respect to the Company under the bankruptcy code, all outstanding obligations under the Credit Agreement shall automatically become immediately due and payable. Loans outstanding under the Credit Agreement will bear interest at a rate of 2.0% per annum in excess of the otherwise applicable rate during the continuance of certain payment or insolvency related events of default and, at the request of the required lenders, during the continuance of any other event of default.

The foregoing description of the Credit Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Credit Agreement, filed herewith as Exhibit 4.1 and incorporated herein by reference.
