PART I - FINANCIAL INFORMATION ITEM 1 - FINANCIAL STATEMENTS A. O. SMITH CORPORATION NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS September 30, 2002 (unaudited) 1. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission. Accordingly, they do not include all of the information and footnotes required for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three- and nine-month periods ended September 30, 2002 are not necessarily indicative of the results expected for the full year. It is suggested that the accompanying condensed consolidated financial statements be read in conjunction with the audited consolidated financial statements and the notes thereto included in the company's latest Annual Report on Form 10-K. Certain prior year amounts have been reclassified to conform to the 2002 presentation. 2. Acquisitions On July 1, 2002, A. O. Smith Corporation (the company) completed the purchase of the hermetic motor assets of the Athens Products (Athens) division of Electrolux Group for cash consideration of $9.6 million. The purchase price was allocated to the assets acquired and liabilities assumed based upon current estimates of their respective fair values at the date of acquisition. On December 28, 2001, the company acquired all of the outstanding stock of State Industries, Inc. (State) for an aggregate purchase price of $117.6 million. This was comprised of $57.8 million for the outstanding stock, assumption of $56.3 million of debt, and $3.5 million of acquisition costs, of which $2.2 million were paid during the nine-month period ended September 30, 2002. The purchase price was allocated to the assets acquired and liabilities assumed based upon current estimates of their respective fair values at the date of acquisition. In connection with our acquisition of Athens in July 2002, we recorded additional purchase liabilities of approximately $4.2 million primarily for employee severance costs associated with product manufacturing repositioning. As of September 30, 2002, we have charged $0.7 million against this reserve. In connection with the Athens acquisition and certain other acquisitions by the company, aggregate additional purchase liabilities of $26.0 million were recorded at the respective acquisition dates for employee severance and relocation, as well as certain facility exit costs. As of September 30, 2002, costs incurred and charged against these liabilities to date totaled $15.4 million. 6

3. Business Improvement Programs In the fourth quarter of 2001, the company recorded restructuring and other charges of $9.4 million. The charges included employee separation costs of $7.7 million associated with product or component manufacturing repositioning and the realignment of certain administrative functions. The resulting reduction of workforce is approximately 150 salaried and 775 hourly employees. In addition, the company recorded facility impairment and lease charges of $1.7 million representing estimated costs of facilities to be vacated. The company spent $2.9 million through September 30, 2002. At September 30, 2002, the company estimates approximately 520 employees are yet to be impacted and plans to be substantially completed with the realignment activities prior to June 30, 2003. 4.

Goodwill and Other Intangible Assets The company adopted Statement of Financial Accounting Standards (SFAS) No. 142, "Goodwill and Other Intangible Assets", effective January 1, 2002. Under SFAS No. 142, goodwill and certain other intangible assets are no longer amortized but are reviewed for impairment. In connection with the adoption of SFAS No. 142, the company has completed the first step of the transitional goodwill impairment test, which requires the company to compare the fair value of its reporting units to the carrying value of the net assets of the respective reporting units as of January 1, 2002. Based on this analysis, the company has concluded that no impairment existed at the time of adoption, and, accordingly, the company has not recognized any transitional impairment loss. Changes in the carrying amount of goodwill during the nine-month period ended September 30, 2002 consist of the following (000 omitted): Electrical Water Products Systems Total ------------ --------- ------------ Balance at December 31, 2001 $ 230,004 $ 65,069 $ 295,073 Adjustment to property, plant and equipment and other assets (22) 260 238 Additional acquisition costs - 398 398 ---------- --------- ---------- Balance at September 30, 2002 $ 229,982 $ 65,727 $ 295,709 ======= ========= ======= As required by SFAS No. 142, the results of operations for periods prior to its adoption have not been restated.

Long-Term Debt The company's credit agreement and term notes contain certain conditions and provisions which restrict the company's payment of dividends. Under the most restrictive of these provisions, retained earnings of $200.6 million were unrestricted as of September 30, 2002. 7. Common Stock Issuance On May 10, 2002, the company completed the sale of 4,776,065 shares of its common stock held in treasury. The $127.5 million net proceeds from the offering were used to reduce long-term debt. 8. Comprehensive Earnings (000 omitted) The company's comprehensive earnings are comprised of net earnings, foreign currency translation adjustments, and realized and unrealized gains and losses on cash flow derivative instruments. Also included in comprehensive earnings for the nine-month period ended September 30, 2001 was a cumulative loss adjustment on cash flow hedges of approximately $0.6 million in connection with the adoption of Statement of Financial Accounting Standards (SFAS) No. 133, "Accounting for Derivative Instruments and Hedging Activities", as amended, on January 1, 2001.

11. Accounting for Derivative Instruments The company utilizes certain derivative instruments to enhance its ability to manage currency exposures and raw materials price risks. Derivative instruments are entered into for periods consistent with the related underlying exposures and do not constitute positions independent of those exposures. The company does not enter into contracts for speculative purposes. The company has hedged certain of its forecasted exposures. Approximately 89 percent of these contracts expire by December 31, 2003. The contracts are executed with major financial institutions with no credit loss anticipated for failure of the counterparties to perform. Foreign Currency Forward Contracts The company is exposed to foreign currency exchange risk as a result of transactions in currencies other than the functional currency of certain subsidiaries. The company utilizes foreign currency forward purchase and sale contracts to manage the volatility associated with foreign currency purchases and certain inter-company transactions in the normal course of business. Contracts typically have maturities of a year or less. Principal currencies include the Mexican peso, Hungarian forint, British pound, Euro and U.S. dollar. Forward contracts are accounted for as cash flow hedges of a forecasted transaction. The fair value of these currency derivatives of $4.9 million has been recorded in accrued liabilities as of September 30, 2002. A fair value of $6.6 million for currency derivatives has been recorded in other current assets as of December 31, 2001. Gains and losses on these instruments are initially recorded in other comprehensive income (loss) and subsequently reclassified into earnings when the underlying transaction affects income. The assessment of effectiveness for forward contracts is based on changes in the forward rates. These hedges have been determined to be perfectly effective. Commodity Future Contracts In addition to entering into supply arrangements in the normal course of business, the company also enters into future contracts to fix the cost of certain raw material purchases, principally copper and aluminum, with the objective of minimizing changes in inventory cost due to market price fluctuations. The commodity future contracts are designated as cash flow hedges of a forecasted transaction. Derivative commodity liabilities for copper of $3.6 million and $6.2 million are recorded in other current liabilities as of September 30, 2002 and December 31, 2001, respectively. Derivative commodity liabilities for aluminum of $0.3 million and $0.7 million are recorded in accrued liabilities as of September 30, 2002 and December 31, 2001, respectively. Overall, the value of the effective portions of the commodity contracts of ($3.3) million and ($6.9) million are recorded in accumulated other comprehensive income (loss) as of September 30, 2002 and December 31, 2001, respectively, and subsequently reclassified into cost of products sold in the period in which the underlying transaction is recorded in earnings. Ineffective portions of the commodity hedges are recorded into earnings in the period in which the ineffectiveness occurs. Hedge ineffectiveness and impact on earnings was not material for the three- and nine-month periods ended September 30, 2002 and 2001, respectively. 10

The majority of the amounts in accumulated other comprehensive earnings (loss) for cash flow hedges are expected to be reclassified into earnings within one year. 11

PART I - FINANCIAL INFORMATION ITEM 2 - MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS RESULTS OF OPERATIONS THIRD QUARTER AND FIRST NINE MONTHS OF 2002 COMPARED TO 2001 Our sales were $352.4 million in the third quarter of 2002 or 31 percent higher than sales of $269.1 million in last year's third quarter. Sales for the first nine months of the year were $1.11 billion or 24 percent higher than sales of $895.6 million in the same period last year. The increase in third quarter sales was due to our acquisitions of State Industries Inc. (State) in December 2001 and Athens Products (Athens) in July 2002 as well as higher sales in the base water heater business. The increase in year-to-date sales was due to the acquisitions partially offset by lower sales of electric motors in the first half of the year. Our gross profit margin for the third quarter of 2002 increased from 15.8 percent in 2001 to 18.8 percent. Our year-to-date gross profit margin in 2002 was 20.2 percent compared with 17.9 percent in the same period in 2001. The improved margins in both the third quarter and first nine months of 2002 resulted from product repositioning at Electrical Products, the addition of State Industries, and material cost savings at both businesses. Our selling, general and administrative (SG&A) expenses in the third quarter and first nine months of 2002 were higher than the same periods in 2001 by $13.0 million and $41.9 million, respectively, primarily as a result of the incremental SG&A associated with our State acquisition. On a year-to-date basis SG&A was 13.7 percent of sales compared with 12.3 percent of sales for the first nine months of 2001. The increase in SG&A relative to sales resulted from our Water Systems business which has higher SG&A levels and has grown from 29.2 percent of our total company sales in the first nine months of 2001 to 44.8 percent of total company sales in the same period of 2002. Interest expense for the third quarter and first nine months of 2002 was lower than the comparable periods in 2001 by $1.0 million and $1.8 million, respectively, due to lower interest rates and reduced debt levels resulting from our stock offering (see Note 7 of Notes to Condensed Consolidated Financial Statements). We have significant pension benefit costs and credits that are developed from actuarial valuation. The valuations reflect key assumptions regarding, among other things, discount rates, expected return on plan assets, retirement ages, and years of service. Consideration is given to current market conditions, including changes in interest rates, in making these assumptions. During the second quarter of 2002, we reduced our assumption for expected rate of return on plan assets from 10.0 percent to 9.75 percent. The amount of pension credit recognized in the third quarter and first nine months of 2002 was $4.1 million and $12.7 million, respectively, and compared with $5.0 million and $15.1 million in the comparable periods of 2001. The third quarter and first nine months of 2002 included $.5 million and $1.7 million for pension expense associated 12

with our State acquisition. The pension credits are reflected as offsets to cost of products sold and SG&A. Our year-to-date effective tax rate was 34.5 percent compared with 35.5 percent for the first nine months of 2001. The effective rate in 2002 benefited from the implementation of a more efficient tax structure for international operations which was initially implemented in the second quarter of 2001 with additional favorable impacts being recognized commencing with the third quarter of 2002. Net earnings for the third quarter improved significantly to $10.0 million from $.4 million in last year's third quarter. Net earnings of $40.1 million for the first nine months of 2002 were more than double the net earnings of $19.6 million recognized in the same period of 2001. The increase in earnings was attributable to lower manufacturing costs and the elimination of goodwill amortization at Electrical Products; synergies from our State acquisition; and higher sales volume in our base Water Systems business. On a diluted per share basis, third quarter earnings increased from $.02 in 2001 to $.34 in 2002, while for the first nine months per share earnings increased from $.82 in 2001 to $1.49 in 2002. The 2002 third quarter and year-to-date earnings per share amounts were diluted by approximately $.04 and $.11, respectively, as a result of increased shares outstanding associated with our stock offering. Electrical Products Third quarter sales for our Electrical Products segment were $197.5 million or $10.9 million higher than the same period last year with the increase attributable to the Athens acquisition at the beginning of the quarter. Sales to the domestic heating, ventilation and air conditioning (HVAC) market were 8 percent lower than in the third quarter of 2001 while sales of motors for pumps, after-market and general industry applications improved more than 10 percent compared with the same period last year. Year-to-date sales for this segment were $612.9 million, a decline of $21.5 million from 2001 nine month sales of $634.4 million. The year-to-date decline occurred mostly in sales to the commercial air conditioning market. Third quarter operating earnings for our Electrical Products segment increased from $3.3 million (as adjusted to exclude $1.7 million of goodwill amortization) to $10.3 million in 2002. Earnings for the first nine months were $46.0 million or $10.0 million higher than 2001 nine month earnings of $35.9 million (as adjusted to exclude $4.9 million of goodwill amortization). The favorable trend in earnings reflects the impact of product repositioning and other cost reduction programs. Water Systems Third quarter and nine month sales for our Water Systems segment increased by $72.3 million and $236.5 million, respectively over the comparable periods in 2001. Sales in 2002 associated with our State acquisition were $68.9 million for the second quarter and $230.9 million for the first nine months, accounting for most of the year over year increase. The remaining increase in sales was attributable to modestly higher volume for the base residential and commercial business and the China operation. Operating earnings for Water Systems were $13.4 million in the third quarter of 2002 reflecting a $4.6 million increase over the same period last year. For the first nine months of 2002, earnings were $43.6 million as compared to $28.6 million for the same period last year. The improved earnings performance in the third quarter and first nine months of 2002 compared with the same 13

periods in 2001 was the result of State Industries and the synergies associated with this acquisition and improved profitability in our China operation. Critical Accounting Policies Our accounting policies are described in Note 1 of Notes to Consolidated Financial Statements as disclosed in the Form 10-K for the fiscal year ended December 31, 2001. Also as disclosed in Note 1, the preparation of financial statements in conformity with accounting principles generally accepted in the United States requires the use of estimates and assumptions about future events that affect the amounts reported in the financial statements and accompanying notes. Future events and their effects cannot be determined with absolute certainty. Therefore, the determination of estimates requires the exercise of judgment. Actual results inevitably will differ from those estimates, and such differences may be material to the financial statements. The most significant accounting estimates inherent in the preparation of our financial statements include estimates associated with the evaluation of the recoverability of certain assets including goodwill and receivables resulting from the payment of claims associated with the dip tube class action lawsuit (see Note 13 of notes to consolidated financial statements in the Form 10-K for the fiscal year ended December 31, 2001) as well as those estimates used in the determination of liabilities related to warranty activity, litigation, product liability, environmental matters and pensions and other post-retirement benefits. Various assumptions and other factors underlie the determination of these significant estimates. The process of determining significant estimates is fact-specific and takes into account factors such as historical experience and trends, and in some cases, actuarial techniques. We constantly reevaluate these significant factors and adjustments are made when facts and circumstances dictate. Historically, actual results have not significantly deviated from those determined using the estimates described above. Recent Accounting Pronouncements The Financial Accounting Standards Board (FASB) has issued Statement of Financial Accounting Standards (SFAS) No. 143, "Accounting for Asset Retirement Obligations", SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets," and SFAS No. 146, "Accounting for Costs Associated with Exit or Disposal Activities." SFAS No. 143 will become effective for us on January 1, 2003. Adoption of this statement is not expected to have a material impact on our consolidated financial statements. SFAS No. 144, which was adopted on January 1, 2002, has not had a material impact on our consolidated financial statements since its adoption. SFAS No. 146 will be effective for exit or disposal activities initiated after December 31, 2002. Management is currently assessing the provisions of SFAS No. 146 but believes there will be no effect on the company's financial position or results of operations at the time of adoption. Outlook The improved margin performance of our operating units is having a positive effect on earnings per share, and consequently, we expect 2002 earnings will range between $1.80 and $1.85 per share. Looking ahead, we believe the challenging market conditions we are now experiencing will continue into 2003, particularly in our electric motor markets. However, the ongoing impact of Electrical Products' cost-reduction actions, combined with the continued benefits of the State integration into Water Systems will have a positive impact on 2003 earnings. Consequently, we estimate that next year's earnings will range between $2.05 and $2.25 per share. 14

Liquidity & Capital Resources Our working capital for continuing operations was $213.1 million at September 30, 2002, $6.7 million lower than at December 31, 2001. The most significant factor impacting working capital was the reduction in our other current assets account as a result of receiving an expected $12.4 million tax refund. Cash provided by our operations during the first nine months of 2002 was $98.4 million compared with $39.3 million during the same period one year ago. We attribute the higher cash flow provided by operations to higher earnings and improved working capital management during the first nine months of 2002 compared with the first nine months of 2001. We project operating cash flow for the full year to approximate current levels. Our 2002 capital expenditures through September 30 totaled $25.8 million, which was slightly higher than the $23.4 million spent in the same period of 2001. The increase in capital spending is associated with our recent acquisition of State Industries. Our company is projecting 2002 capital expenditures of approximately $40 to $45 million, an increase over 2001 capital expenditures of $35.3 million primarily due to the acquisition of State. We believe that our facilities and planned capital expenditures are sufficient to provide capacity for our operations in the near term. With the net proceeds from our stock offering completed earlier this year, coupled with strong operating cash flow, we reduced our total debt by $174.9 million to $232.0 million at September 30, 2002. Our leverage as measured by the ratio of total debt to total capitalization was 27 percent, down significantly from 47 percent at the end of 2001. We did not enter into any significant operating leases during the first nine months of 2002. At September 30, 2002, our company had available borrowing capacity of $247.4 million under our credit facilities. We believe that the combination of available borrowing capacity and operating cash flow will provide sufficient funds to finance our existing operations for the foreseeable future. In connection with our acquisition of Athens in July 2002, we recorded additional purchase liabilities of approximately $4.2 million primarily for employee severance costs associated with product manufacturing repositioning. As of September 30, 2002, we have charged $0.7 million against this reserve. In connection with the Athens acquisition and certain other acquisitions by the company, aggregate additional purchase liabilities of $26.0 million were recorded at the respective acquisition dates for employee severance and relocation, as well as certain facility exit costs. As of September 30, 2002, costs incurred and charged against these liabilities to date totaled $15.4 million. We expect the majority of the respective activities to be completed within the next year. The recent decline in the U.S. equity markets has resulted in a decrease in the value of the assets of our pension plan. We currently estimate that the accumulated benefit obligation of our primary defined benefit pension plan exceeds the fair value of plan assets by approximately $40 million. If the U.S. equity markets do not recover by the plan's measurement date in the fourth quarter, and we choose not to fund the difference between the accumulated benefit obligation and the fair value of plan assets, we will be required to record a charge to stockholders' equity for that difference as well as the elimination of the current prepaid pension asset. This direct charge to equity, which would be approximately $100 million net of tax, would have no impact on cash or net income. If the charge is recorded it will result in an increase to our leverage ratio from 27 percent to approximately 31 percent. 15

On October 11, 2002, our board of directors declared a quarterly dividend on our Common Stock and Class A Common Stock of $.14 per share. The dividend is payable on November 15, 2002 to stockholders of record on October 31, 2002. ITEM 3 - QUANTITATIVE AND QUALITATIVE DISCLOSURE OF MARKET RISK As is more fully described in our annual report on Form 10-K for the year ended December 31, 2001, we are exposed to various types of market risks, primarily currency and certain commodities. We monitor our risks in these areas on a continuous basis and generally enter into forward and futures contracts to minimize these exposures for periods of less than one year. Our company does not engage in speculation in our derivative strategies. It is important to note that gains and losses from our forward and futures contract activities are offset by changes in the underlying costs of the transactions being hedged. ITEM 4 - CONTROLS AND PROCEDURES Evaluation of disclosure controls and procedures Our chief executive officer and chief financial officer, after evaluating the effectiveness of the company's disclosure controls and procedures, have concluded that these disclosure controls and procedures were adequate and effective to ensure that material information relating to the company and its consolidated subsidiaries would be made known to them by others within those entities. Changes in internal controls There were no significant changes in our internal controls or in other factors that could significantly affect our disclosure controls and procedures subsequent to the date of their evaluation, nor were there any significant deficiencies or material weaknesses in our internal controls. As a result, no corrective actions were required or undertaken. Forward Looking Statements This document contains statements that we believe are "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements generally can be identified by the use of words such as "may," "will,""expect," "intend," "estimate," "anticipate," "believe," "continue," or words of similar meaning. These forward-looking statements are subject to risks and uncertainties that could cause actual results to differ materially from those anticipated as of the date of this release. Factors that could cause such a variance include the following: instability in the company's electric motor and water products markets; inability to timely and properly integrate the acquisition of State Industries; the inability to implement cost-reduction programs; adverse changes in general economic conditions; significant increases in raw material prices; competitive pressures on the company's businesses; and the potential that assumptions on which the company based its expectations are inaccurate or will prove to be incorrect. Forward-looking statements included in this document are made only as of the date of this filing, and the company is under no obligation to update these statements to reflect subsequent events or circumstances. All subsequent written and oral forward-looking statements attributable to the company, or persons acting on its behalf, are qualified in their entirety by these cautionary statements. 16
