Organization. A. O. Smith Corporation (A. O. Smith or the Company) is comprised of two reporting segments: North America and Rest of World. The Rest of World segment is primarily comprised of China, India, and Europe. Both segments manufacture and market comprehensive lines of residential and commercial gas and electric water heaters, boilers, tanks and water treatment products. Both segments primarily manufacture and market in their respective regions of the world.

Use of estimates. The preparation of financial statements in conformity with accounting principles generally accepted in the United States (U.S.) requires management to make estimates and assumptions that affect the amounts reported in the accompanying financial statements and notes. Actual results could differ from those estimates.

Fair value of financial instruments. The carrying amounts of cash, cash equivalents, marketable securities, receivables, floating rate debt and trade payables approximated fair value as of December 31, 2025 and 2024, due to the short maturities or frequent rate resets of these instruments. The fair value of term notes with financial institutions included in Long-term debt within the consolidated balance sheets was approximately $139.0 million as of December 31, 2025 compared with the carrying amount of $155.0 million for the same date. The fair value of term notes with financial institutions was approximately $143.6 million as of December 31, 2024 compared with the carrying amount of $163.2 million.

Foreign currency translation. For all subsidiaries outside the U.S., with the exception of its Barbados, Hong Kong and Mexican companies and its non-operating companies in the Netherlands, the Company uses the local currency as the functional currency. For those operations using a functional currency other than the U.S. dollar, assets and liabilities were translated into U.S. dollars at year-end exchange rates, and revenues and expenses were translated at weighted-average exchange rates. The resulting translation adjustments were recorded as a separate component of stockholders’ equity. The Barbados, Hong Kong, Mexican and non-operating Netherlands companies use the U.S. dollar as the functional currency. Gains and losses from foreign currency transactions were included in net earnings and were not significant in 2025, 2024, or 2023.

Marketable securities. The Company considers all highly liquid investments with maturities greater than 90 days when purchased to be marketable securities. At December 31, 2025, the Company’s marketable securities consisted of bank time deposits with original maturities ranging from 180 days to 12 months and were primarily located at investment grade rated banks in China and Hong Kong.

Inventory valuation. Inventories are carried at lower of cost or net realizable value. Cost is determined on the last-in, first-out (LIFO) method for a certain portion of the Company’s domestic inventories, which comprised 40 percent and 43 percent of the Company’s total inventory at December 31, 2025 and 2024, respectively. The inventories of foreign subsidiaries and the remaining domestic inventories and supplies were determined using the first-in, first-out (FIFO) method.

Property, plant and equipment. Property, plant and equipment are stated at cost. Depreciation is computed primarily by the straight-line method. The estimated service lives used to compute depreciation are generally 25 to 50 years for buildings, three to 20 years for equipment and three to 15 years for software. Maintenance and repair costs are expensed as incurred.

Goodwill and other intangibles. Goodwill and indefinite-lived intangible assets are not amortized but are reviewed for impairment on an annual basis. Separable intangible assets, primarily comprised of customer relationships, that are not deemed to have an indefinite life are amortized on a straight-line basis over their estimated useful lives which range from two to 25 years.

Impairment of long-lived and amortizable intangible assets. Property, plant and equipment and intangible assets subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the sum of the expected undiscounted cash flows is less than the carrying value of the related asset or group of assets, a loss is recognized for the difference between the fair value and carrying value of the asset or group of assets. Such analyses involves significant judgment.

Product warranties. The Company’s products carry warranties that generally range from one to twelve years and are based on terms that are consistent with the market. The Company records a liability for the expected cost of warranty-related claims

at the time of sale and is estimated based on the warranty period, product type and loss experience using actual historical failure rates and estimated costs of product replacement. The variables used in the calculation of the provision are reviewed by the Company at least annually. At times, warranty issues may arise which are beyond the scope of the Company’s historical experience. The Company provides for any such warranty issues as they become known and estimable. The allocation of the warranty liability between current and long-term is based on expected warranty claims to be settled in the next year as determined by historical product failure rates.

Derivative instruments. The Company utilizes certain derivative instruments to enhance its ability to manage currency as well as raw materials price risk. The Company does not enter into contracts for speculative purposes. The fair values of all derivatives are recorded in the consolidated balance sheets. The change in a derivative’s fair value is recorded each period in current earnings or accumulated other comprehensive loss (AOCL), depending on whether the derivative is designated as part of a hedge transaction and if so, the type of hedge transaction. See Note 13, “Derivative Instruments” for disclosure of the Company’s derivative instruments and hedging activities.

Fair Value Measurements. Accounting Standards Codification (ASC) 820 Fair Value Measurements, defines fair value, establishes a consistent framework for measuring fair value and expands disclosure for each major asset and liability category measured at fair value on either a recurring basis or nonrecurring basis. ASC 820 clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, ASC 820 establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: (Level 1) observable inputs such as quoted prices in active markets; (Level 2) inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and (Level 3) unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.


Fair Value Measurement Using	Balance Sheet Location	December 31, 2025		December 31, 2024
Quoted prices in active markets for identical assets (Level 1)	Marketable Securities	$	18.7	$	36.5
Significant other observable inputs (Level 2)	Accrued liabilities	—		(1.9)

Revenue recognition. Substantially all of the Company’s sales are from contracts with customers for the purchase of its products. Contracts and customer purchase orders are used to determine the existence of a sales contract. Shipping documents are used to verify shipment. For substantially all of its products, the Company transfers control of products to the customer at the point in time when title and risk are passed to the customer, which generally occurs upon shipment of the product. See Note 2, “Revenue Recognition” for disclosure of the Company’s revenue recognition activities.

Advertising. The majority of advertising costs are charged to operations as incurred and totaled $101.1 million, $100.3 million and $93.9 million during 2025, 2024 and 2023, respectively. Included in total advertising costs are expenses associated with store displays for water heater, water treatment products, and kitchen products in China that are amortized over 12 to 48 months which totaled $24.0 million, $21.1 million and $15.2 million during 2025, 2024 and 2023, respectively.

Environmental costs. The Company accrues for costs associated with environmental obligations when such costs are probable and reasonably estimable. Costs of estimated future expenditures are not discounted to their present value. Recoveries of environmental costs from other parties are recorded as assets when their receipt is considered probable. The accruals are adjusted as facts and circumstances change.

Stock-based compensation. Compensation cost is recognized using the straight-line method over the vesting period of the award and forfeitures are recognized as they occur. In accordance with amended ASC 718 Compensation-Stock Compensation, the Company recognized $0.6 million, $4.1 million, and $3.2 million of discrete income tax benefits on settled stock based compensation awards during 2025, 2024, and 2023 respectively.

Income taxes. The provision for income taxes is computed using the asset and liability method, in accordance with ASC 740 Income Taxes, under which deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities and for operating losses and tax credit carryforwards. Deferred tax assets and liabilities are measured using the currently enacted tax rates that apply to taxable income in effect for the years in which those tax assets are expected to be realized or settled and are classified as noncurrent in the consolidated balance sheet. The Company records a valuation allowance to reduce deferred tax assets to the amount that is believed more likely than not to be realized.

The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such positions are then measured based on the largest benefit that has a greater than 50 percent likelihood of being realized upon settlement.

Earnings per share of common stock. The Company is not required to use the two-class method of calculating earnings per share because its Class A Common Stock and Common Stock have equal dividend rights. The numerator for the calculation of basic and diluted earnings per share is net earnings. The following table sets forth the computation of basic and diluted weighted-average shares used in the earnings per share calculations:


	2025	2024	2023
Denominator for basic earnings per share - weighted-average shares outstanding	141,029,845	145,997,584	149,952,679
Effect of dilutive stock options, restricted stock and share units	884,995	1,086,496	1,062,895
Denominator for diluted earnings per share	141,914,840	147,084,080	151,015,574

In September 2025, the FASB issued ASU No. 2025-06, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40), which modernizes the accounting guidance for internal-use software costs by eliminating the requirement to assess software development stages and introduces a new capitalization threshold. ASU 2025-06 is effective for fiscal years beginning after December 15, 2027, with early adoption permitted. The Company is currently in the process of reviewing the guidance and evaluating its impact on its financial statements.

In November 2024, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2024-03 “Income Statement - Reporting Comprehensive Income (Topic 220): Disaggregation of Income Statement Expenses.” The ASU requires additional disclosures by disaggregating the costs and expense line items that are presented on the face of the income statement. The ASU is effective for the Company beginning with its 2027 annual disclosures and subsequent interim periods. Early adoption is permitted. This ASU requires a public company to apply the amendments either prospectively to financial statements issued for reporting periods after the effective date of this ASU or retrospectively to any or all prior periods presented in the financial statements. The Company is currently evaluating the impact of adopting this ASU on its disclosures.
