PART I - FINANCIAL INFORMATION ITEM 1 - FINANCIAL STATEMENTS A. O. SMITH CORPORATION NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS June 30, 2003 (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 six-month periods ended June 30, 2003 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 2003 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 $9.7 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. In late 2002, the company acquired the motor manufacturing assets of Jiangsu Changheng Group Co. Ltd. (Changheng) for a total of $15.3 million including future payments of $3.8 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. In connection with the Athens acquisition and other acquisitions by the company, aggregate additional purchase liabilities of $26.5 million were recorded at the respective acquisition dates for employee severance and relocation, as well as certain facility exit costs. As of June 30, 2003, costs incurred and charged against these liabilities to date totaled $18.2 million. 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 6

spent $5.0 million through June 30, 2003 for employee severance and separation costs. At June 30, 2003, the company estimates approximately 180 employees are yet to be impacted. The realignment activities will be substantially completed prior to December 31, 2003. 4. Inventories (dollars in millions) June 30, 2003 December 31, 2002 ------------- ----------------- Finished products $ 150.2 $ 130.7 Work in process 45.2 39.7 Raw materials 66.1 58.3 --------- --------- 261.5 228.7 LIFO reserve 28.3 28.3 --------- --------- $ 233.2 $ 200.4 ========= ========= 5. 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 $111.6 million were unrestricted as of June 30, 2003. During June 2003, the company issued $50 million in senior notes with various insurance companies. The notes range in maturity between 2013 and 2016 and carry a weighted-average interest rate of slightly less than 4.5%. The proceeds of the notes were used to repay commercial paper and revolver borrowing. 6. Product Warranty (dollars in millions) The company offers warranties on the sales of certain of its products and records an accrual for the estimated future claims. Such accruals are based upon historical experience and management's estimate of the level of future claims. The following table presents the company's warranty liability activity for the six-months ended June 30, 2003 and 2002, respectively: 2003 2002 -------- -------- Balance at January 1 $ 70.5 $ 69.6 Expense 14.1 16.7 Claims settled (15.3) (14.7) ------- ------- Balance at June 30 $ 69.3 $ 71.6 ======= ======= 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. 7

8. Comprehensive Earnings (dollars in millions) 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.

10. Stock Based Compensation The company has one stock-based employee compensation plan as more fully described in Note 11 of Notes to Consolidated Financial Statements of the Company's 2002 annual report on Form 10-K. SFAS No. 123, "Accounting for Stock-Based Compensation," encourages, but does not require companies to record compensation cost for stock-based employee compensation plans at fair value. The company has chosen to continue applying Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees," and related interpretations in accounting for its stock option plan. Accordingly, because the number of shares is fixed and the exercise price of the stock options equals the market price of the underlying stock on the date of grant, no compensation expense has been recognized. Had compensation cost been determined based upon the fair value at the grant date for awards under the plans based on the provisions of SFAS No. 123, the company's pro forma earnings and earnings per share would have been as follows: Three months ended Six months ended June 30 June 30 (dollars in millions, ------------------ ----------------- except per share amounts) 2003 2002 2003 2002 - ----------------------------------------- ------- ------- ------- ------- Earnings: As reported $ 19.8 $ 18.0 $ 33.5 $ 30.1 Deduct: Total stock based employee compensation expense determined under fair value based method, net of tax (0.4) (0.4) (0.9) (0.8) ------ ------ ------ ------ Pro forma $ 19.4 $ 17.6 $ 32.6 $ 29.3 ====== ====== ====== ====== Earnings per share: As reported: Basic $ 0.68 $ 0.68 $ 1.16 $ 1.20 Diluted 0.67 0.66 1.13 1.17 Pro forma: Basic $ 0.67 $ 0.66 $ 1.13 $ 1.17 Diluted 0.65 0.65 1.10 1.14 9

PART I - FINANCIAL INFORMATION ITEM 2 - MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS RESULTS OF OPERATIONS SECOND QUARTER AND FIRST SIX MONTHS OF 2003 COMPARED TO 2002 Sales were $417.6 million in the second quarter of 2003, approximately eight percent higher than sales of $386.3 million in the second quarter of 2002. Sales for the first half of 2003 were $805.5 million or six percent higher than sales of $758.2 million in the same period last year. The increase in second quarter and first half sales was due primarily to our acquisitions of Athens Products (Athens) and Jiangsu Changheng Group Co. Ltd. in the last half of 2002 as well as higher residential gas water heater volume. Our gross profit margin for the second quarter and first half of 2003 was 20.1 percent. Our gross profit margins for the second quarter and first half of 2002 were 21.1 percent and 20.9 percent, respectively. Much of the decline in our gross profit margins was due to increased steel prices, lower margin sales of recent acquisitions in our motor business, and unfavorable sales mix in the water heater operation. Selling, general and administrative expenses in the second quarter and first half of 2003 were higher than the same periods in 2002 by $1.5 million and $2.3 million, respectively. The increase was due to the aforementioned acquisitions and was partially offset by cost reduction activities within our operating units and an insurance settlement of $.9 million recognized in the second quarter. Interest expense for the second quarter and first half of 2003 was lower than the comparable periods in 2002 by $.7 million and $2.0 million, respectively, due to reduced debt levels throughout most of the first six months resulting from our May 10, 2002 stock offering and lower interest rates. 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. Our assumption for the expected rate of return on pension plan assets is 9.0 percent in 2003 compared with 9.75 percent in 2002. Pension income recognized in the second quarter and first half of 2003 was $3.4 million and $5.8 million, respectively, and compared with $4.1 million and $8.6 million in the comparable periods of 2002. Our pension income is reflected as reductions to cost of products sold and selling, general, and administrative expense. Other expense decreased from $.7 million in the first half of 2002 to $.3 million in the first half of 2003 due mostly to a non-recurring gain on the sale of securities in the first quarter of 2003. Our effective tax rates for the second quarter and first half of 2003 were 32.1 percent and 33.1 percent, respectively, and were both favorably impacted by release of a $.7 million reserve upon 11

resolution of a federal tax audit in May 2003. The effective rate for the total year 2003 should approximate 34.0 percent. Our effective tax rate for the second quarter and first half of 2002 was 35.0 percent. The lower rates in 2003 were due to the aforementioned tax audit resolution and continued optimization of the tax structure of our international operations. Net earnings for the second quarter were $19.8 million, surpassing the same quarter last year by $1.8 million. Net earnings of $33.5 million for the first half of 2003 were $3.4 million higher than net earnings of $30.1 million in the first half of 2002. The increase in earnings in both the second quarter and first half was attributable to lower interest expense, a liquidation distribution from a bankrupt insurer, and a favorable resolution of a tax credit issue. Second quarter diluted earnings per share increased from $.66 in 2002 to $.67 in 2003 overcoming most of the $.05 per share dilutive impact of the May 2002 stock offering of 4.8 million shares. On a year-to-date basis, diluted earnings per share declined to $1.13 from $1.17 in the same period last year. The dilutive impact of the May 2002 stock offering was $.13 per share in the first half of 2003. Electrical Products Second quarter sales for our Electrical Products segment were $227.6 million, approximately $8.4 million higher than sales of $219.2 million in the second quarter of 2002. Year-to-date sales for this segment were $440.7 million, an increase of $25.3 million from 2002 first half sales of $415.4 million. The increase in sales for the second quarter and first half was the result of our July 2002 acquisition of Athens and additional sales from our recently acquired Chinese motor operations. The additional sales from our acquisitions were partially offset by a five percent decline in sales of heating and air conditioning motors and pump motors as a result of cooler than normal weather conditions during the second quarter in the northern United States. Operating earnings for our Electrical Products segment in the second quarter were $18.6 million or approximately nine percent lower than the $20.5 million of operating earnings in the second quarter of 2002. The decline in earnings was due mostly to the weather related decline in the base business sales. First half operating earnings in 2003 were higher than the same period in 2002 by $.5 million reflecting the favorable impact of cost reduction initiatives. During the second quarter we closed the Athens, Tennessee plant and announced that our Ripley, Tennessee facility will cease production in July. Water Systems Second quarter and first half sales for our Water Systems segment both increased by approximately $22.0 million over the comparable periods in 2002. The higher sales were the result of a price increase introduced early in the year to offset increased steel costs, incremental sales of residential gas water heaters in advance of introducing the new higher cost flammable vapor ignition resistant product, and a substantial increase in sales at our Chinese operation. Sales of commercial product declined less than five percent in the second quarter when compared to the same period in 2002 due to a weak commercial construction market. Operating earnings for our Water Systems segment were $17.8 million in the second quarter, over seven percent higher than the second quarter of 2002. While operating earnings improved, margins were adversely impacted by the unfavorable commercial and residential product mix. Operating earnings for the first half of 2003 were $29.8 million, slightly less than earnings of 12

$30.2 million in the same period last year. The lower first half earnings reflect the impact of increased steel costs. We recently announced plans to consolidate the North American manufacture of residential water heaters at our Ashland City, Tennessee, and Juarez, Mexico, facilities. This initiative will involve transferring residential production from the McBee, South Carolina plant and will be complete by the first quarter of 2004. We are also consolidating most of our commercial manufacturing in the McBee plant by relocating production from Ashland City and our El Paso, Texas, boiler plant. Outlook The company's overall cost structure has improved significantly over the last year and a half, and our operating units will continue to aggressively manage cost as we go forward. We project per share earnings of $.42 to $.46 in the third quarter. We also are reaffirming and narrowing our guidance for full-year 2003 earnings to a range of between $2.10 and $2.25 per share. While we don't anticipate any rebound in our served markets in 2003, the impact of operating improvements and new products will materialize and accelerate during the second half of the year. These improvements include the continued success of the motor repositioning programs and the ongoing integration of the State Industries acquisition. In addition to these operating improvements, the introduction of new water heater products during the second half of the year will generate additional sales and earnings. As a consequence, we expect earnings per share comparisons to improve significantly in the third and fourth quarters of this year. Liquidity & Capital Resources Our working capital was $298.4 million at June 30, 2003, $71.8 million higher than at December 31, 2002. The majority of the increase resulted from increases in accounts receivable of $57.0 million due to higher sales and higher inventory levels of $32.8 million partially related to product repositioning. These increases were partially offset by increases in accounts payable of $31.3 million. Cash used in operating activities during the first half of 2003 was $6.1 million compared with $50.2 million of cash provided by operating activities during the same period in 2002. Essentially all of the difference is due to the higher investment in working capital, as described above, during the first half of 2003 compared with the first half of 2002, and the receipt of a $12.4 million tax refund in the first half of 2002. We project cash provided by operating activities of $80 to $90 million for the full year due to improved working capital levels and second half earnings. Our capital expenditures during the first half of 2003 totaled $14.8 million, which was slightly less than the capital spending during the same period last year. However, for the full year, we are projecting 2003 capital expenditures of approximately $45 million, slightly more than the $42.5 million spent during the full year last year. We expect that cash flow during 2003 will adequately cover planned capital expenditures. We believe that our present facilities and planned capital expenditures are sufficient to provide adequate capacity for our operations in 2003. Our total debt increased by $29.3 million from $250.8 million at December 31, 2002 to $280.1 million at June 30, 2003. Our leverage as measured by the ratio of total debt to total 13

capitalization was 34%, up slightly from the 33% at the end of 2002. We did not enter into any significant operating leases during the first six months of 2003. To take advantage of historically low long-term borrowing rates, during June our company issued $50 million in senior notes with various insurance companies. The notes range in maturity between 2013 and 2016 and carry a weighted-average interest rate of slightly less than 4.50%. The proceeds of the notes were used to repay commercial paper and revolver borrowing. At June 30, 2003, our company had available borrowing capacity of $239.8 million under our credit facilities. As a result of the new term notes in our capital structure (described above), we have chosen not to renew our $82.5 million 364 day credit facility that expires on July 25, 2003. We believe that the remaining 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 acquisitions, we have recorded aggregate purchase liabilities of $26.5 million at the respective acquisition dates for employee severance and relocation as well as certain facility exit costs. As of June 30, 2003, we incurred and charged $18.2 million against these liabilities. We expect the majority of the activities to be completed by December 31, 2003. On July 8, 2003, our board of directors increased the quarterly dividend from $.14 per share to $.15 per share on our Common stock and Class A common stock, which is payable on August 15, 2003 to stockholders of record on July 31, 2003. 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, 2002. 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 impairment of goodwill, as well as the recoverability of receivables resulting from the payment of claims associated with the dip tube class action lawsuit (see Note 14 of notes to consolidated financial statements in the Form 10-K for the fiscal year ended December 31, 2002). There are also significant 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. Recent Accounting Pronouncements The Financial Accounting Standards Board (FASB) has issued SFAS No. 143, "Accounting for Asset Retirement Obligations", SFAS No. 146, "Accounting for Costs Associated with Exit or Disposal Activities," SFAS No. 148, "Accounting for Stock-Based Compensation - Transition and Disclosure", and FASB Interpretation Number ("FIN") 46, "Consolidation of Variable Interest Entities." SFAS No. 143, which was adopted on January 1, 2003, did not have a material impact on our consolidated financial statements since its adoption. SFAS No. 146 is effective for exit or disposal activities initiated after December 31, 2002. Adoption of this statement did not have a material impact on our consolidated financial statements. Effective December 31, 2002, we began making the disclosures required under SFAS No. 148. To date, FIN 46 has not had a material impact on our consolidated financial statements nor is FIN 46 expected to have a material impact on our consolidated financial statements in the future. 14

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, 2002, 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 The chief executive officer and chief financial officer have evaluated the effectiveness of the company's disclosure controls and procedures within the 90-day period prior to the filing of this report and 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," "expectation", 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 filing. Factors that could cause such a variance include the following: instability in the company's electric motor and water products markets; inability to generate the synergistic cost savings from 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. 15

PART II - OTHER INFORMATION ITEM 1 - LEGAL PROCEEDINGS There have been no material changes in the legal and environmental matters previously reported in Part 1, Item 3 and Note 14 of the Notes to Consolidated Financial Statements in the company's Form 10-K Report for the year ended December 31, 2002. ITEM 4 - SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS On March 5, 2003, the company mailed a proxy statement to its stockholders relating to the annual meeting of stockholders on April 7, 2003. The annual meeting included the election of directors and the ratification of Ernst & Young LLP as the independent auditors of the company for 2003. Directors are elected by a plurality of votes cast, by proxy or in person, with the holders voting as separate classes. A plurality of votes means that the nominees who receive the greatest number of votes cast are elected as directors. Consequently, any shares which are not voted, whether by abstention, broker nonvotes or otherwise, will have no effect on the election of directors. For all other matters considered at the meeting, both classes of stock vote together as a single class, with the Class A Common Stock entitled to one vote per share and the Common Stock entitled to 1/10th vote per share. All such other matters are decided by a majority of the votes cast. On such other matters, an abstention will have the same effect as a "no" vote but, because shares held by brokers will not be considered to vote on matters as to which the brokers withhold authority, a broker nonvote will have no effect on the vote. 1.
