PART I - FINANCIAL INFORMATION
ITEM 1 - FINANCIAL STATEMENTS

                             A. O. SMITH CORPORATION
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                 March 31, 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-month period ended March 31, 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 December 28, 2001, A. O. Smith Corporation (the company) acquired all
      of the outstanding stock of State Industries, Inc. (State) for an
      aggregate purchase price of $117.5 million. This was comprised of $57.8
      million for the outstanding stock, assumption of $56.3 million of debt,
      and $3.4 million of acquisition costs, of which $2.1 million were paid
      during the three-month period ended March 31, 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 the State acquisition, additional purchase
      liabilities of $3.9 million were recorded for employee severance. As of
      March 31, 2002, total costs incurred and charged against this liability to
      date totaled $0.6 million.

      On August 2, 1999, the company acquired the assets of MagneTek, Inc.'s
      (MagneTek) domestic electric motor business and six wholly owned foreign
      subsidiaries for $244.6 million. In connection with the MagneTek
      acquisition, the company recorded additional purchase liabilities of $17.9
      million, which included employee severance and relocation, as well as
      certain facility exit costs. The remaining balance of such purchase
      liabilities at March 31, 2002 is $6.0 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 $1.5 million through March 31, 2002 for employee severance and
      separation costs. As a result of actions taken through March 31, 2002, the
      workforce has been reduced by approximately 94 employees. The company
      expects to be substantially completed with the realignment activities
      prior to December 31, 2002.

5.    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 first quarter of
      2002 consist of the following (000 omitted):

      to its adoption have not been restated. The following table reconciles

      Amortization expense is projected to be approximately $0.2 million for
      each of the fiscal years ended December 31, 2002 through 2006.

6.    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 $66.6
      million were unrestricted as of March 31, 2002.

7.    Comprehensive Earnings  (000 omitted)
      The company's comprehensive earnings were 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 three-month period ended March 31, 2001 was
      a cumulative loss on cash flow hedges of approximately $0.6 million in
      connection with the adoption of SFAS No. 133, "Accounting for Derivative
      Instruments and Hedging Activities", as amended, on January 1, 2001.

      Intersegment sales, which are immaterial, have been excluded from segment
      revenues.

10.   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.
      Greater than 98 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 intercompany 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.

                                       10


      Forward contracts are accounted for as cash flow hedges of a forecasted
      transaction. The fair value of these currency derivatives of $5.9 million
      and $6.6 million have been recorded in other current assets as of March
      31, 2002 and December 31, 2001, respectively. Gains and losses on these
      instruments are recorded in other comprehensive income(loss) until the
      underlying transaction is recorded in earnings. When the hedged item is
      realized, gains or losses are reclassified from accumulated other
      comprehensive income(loss) to the statement of earnings. 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, 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 of $1.2 million
      and $6.9 million are recorded in accrued liabilities as of March 31, 2002
      and December 31, 2001, respectively, with the value of the effective
      portion of the contracts of $0.8 million and $6.9 million recorded in
      accumulated other comprehensive income(loss) as of March 31, 2002 and
      December 31, 2001, respectively, and 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-month periods ended March 31, 2002 and 2001, respectively.

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

11.   Subsequent Event
      On April 12, 2002, the company filed a Registration Statement on Form S-3
      (Reg. No. 333-86074) with the Securities and Exchange Commission to sell
      up to 4,025,000 shares of common stock.

PART I - FINANCIAL INFORMATION
ITEM 2 -  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
          CONDITION AND RESULTS OF OPERATIONS

RESULTS OF OPERATIONS
FIRST THREE MONTHS OF 2002 COMPARED TO 2001

First Quarter 2002 and 2001
Sales in the first quarter of 2002 were $371.9 million, an increase of $53.7
million or 16.9 percent over sales of $318.2 million in the first quarter of
2001. Increased year-over-year first quarter sales for our water systems segment
of $83.7 million more than offset a decline in sales of $30.0 million for our
electrical products segment. The significant increase in first quarter sales of
our water systems segment was attributable to the $84.1 million of sales
associated with our acquisition of State Industries on December 28, 2001. The
decline in electrical products segment sales reflects continued softness in the
electric motor market.

Our gross profit margin was 20.7 percent in the first quarter of 2002 compared
with the 18.5 percent margin achieved in the first quarter of 2001. The increase
was the result of cost reductions in our electrical products segment and the
addition of State Industries.

Selling, general and administrative expense for the first quarter of 2002 was
$53.2 million or $15.1 million higher than the $38.1 million expense in the
first quarter of 2001. The increase in selling, general and administrative
expense was the result of the additional $14.0 million of expense associated
with State Industries and a $1.7 million charge associated with the
consolidation of water systems' management staff. This increase was partially
offset by reduced selling, general and administrative expense in our electrical
products segment resulting from the business improvement programs announced in
the fourth quarter of 2001.

Interest expense in the first quarter of 2002 declined to $4.2 million from $4.8
million in the first quarter of 2001. While our debt levels were higher in the
first quarter of 2002 than the same quarter last year, a significant decline in
interest rates resulted in reduced interest expense.

We have significant pension benefit costs and credits we develop from actuarial
valuations. These valuations reflect key assumptions regarding, among other
things, discount rates, expected returns on plan assets, retirement ages and
years of service. We are required to consider current market conditions,
including changes in interest rates, in making these assumptions. Changes in
related pension costs or credits may occur in the future as a result of changes
affecting the assumptions. We recognized $4.5 million of pension credits in the
first quarter of 2002 including $0.6 million of pension expense associated with
the State Industries acquisition. In the first quarter of 2001, we recognized
$4.5 million of pension credits, and in all of 2001, we recognized pension
credits of $20.2 million. These credits are reflected as offsets to cost of
products sold and selling, general and administrative expense.

Our effective tax rate declined from 37.0 percent in the first quarter of 2001
to 35.0 percent in the first quarter of 2002 due primarily to the implementation
of a more efficient tax structure for international operations.

                                       12


Net earnings in the first quarter of 2002 were $12.1 million or $3.6 million
higher than net earnings of $8.5 million in the first quarter of 2001. On a per
share basis, net earnings in the first quarter of 2002 were $.50 compared to the
$.36 in the first quarter of 2001. The increase in earnings was primarily
attributable to increased earnings for our water systems segment (discussed
subsequently), the elimination of goodwill amortization of $1.6 million, and the
aforementioned $0.6 million decrease in interest expense.

Electrical Products
First quarter sales for our electrical products segment were $196.2 million or
$30.0 million lower than sales of $226.2 million in the same period last year,
and reflect continued softness in the electric motor market. Our heating,
ventilation and air conditioning (HVAC) and pump business declined approximately
15 percent during the quarter compared to last year, with the remainder of the
business down approximately ten percent. Though air conditioning inventory
replenishment is progressing slower than we had anticipated at the beginning of
the year, we believe air conditioning inventories remain at historically low
levels and offer sales upside as we progress through the year.

Operating earnings for our electrical products segment in the first quarter of
2002 were $15.1 million or $0.5 million less than the $15.6 million of operating
earnings in the first quarter of 2001, as adjusted to exclude $1.6 million of
goodwill amortization. Notwithstanding this decrease in operating earnings,
operating margins improved from 6.9 percent to 7.7 percent. The favorable trend
in our year-over-year operating margin for electrical products was the result of
cost reduction activities, including those announced in the fourth quarter of
2001.

Water Systems
First quarter sales for our water systems segment were $175.7 million, or $83.7
million higher than sales of $92.0 million in the same period last year. The
increase in sales was associated with our State Industries acquisition which
recorded sales of $84.1 million in the first quarter. Excluding the State
acquisition, sales in the water systems segment were flat. Higher sales in the
commercial and China business offset a modest decline in residential and other
products.

Operating earnings for our water systems segment in the first quarter of 2002
were $13.6 million, which included $3.8 million of earnings associated with the
State Industries acquisition. The net $9.8 million of earnings for our base
water heater business compared to first quarter 2001 profits of $9.9 million and
included a $1.7 million charge associated with the consolidation of water
systems' management staff.

Outlook
We previously issued a forecast for 2002 that called for earnings to range
between $1.40 to $1.60. Although we continue to be cautious about the timing and
magnitude of the market recovery in 2002, we have improved our earnings
projection to a range of $1.60 to $1.70 per share. This increase is based on the
early and projected continued success of our cost-reduction programs and the
integration of State Industries and is based on share levels currently
outstanding. On the same basis, we expect second quarter earnings per share to
be similar to or slightly higher than first quarter levels.

                                       13


Our earnings expectations for 2002 also are based on a number of other
assumptions, including: no declines in consumer spending or weakening of the
economy compared with current levels; normal U. S. weather conditions during the
spring and summer of 2002; and no material price changes for raw materials,
including steel, aluminum, and copper.

Liquidity & Capital Resources
Our working capital for continuing operations was $227.0 million at March 31,
2002, $7.2 million higher than at December 31, 2001. A sales-related increase in
accounts receivable of $27.8 million was partially offset by increases in
accounts payable and a reduction in our other current assets account as a result
of receiving an expected $12.4 million tax refund in the first quarter of 2002.
Cash provided by our operations during the first quarter of 2002 was $22.9
million compared with $13.3 million of cash used by our operations during the
same period in 2001. We had higher earnings and smaller increases to working
capital during the first quarter of 2002 compared with the first quarter of
2001. We project operating cash flow of $75 to $80 million for the full year.

Our capital expenditures during the first quarter of 2002 totaled $7.1 million,
which was less than the $9.5 million spent in the first quarter of 2001 due to
lower spending by our electrical products segment. We are projecting 2002
capital expenditures of $45 million, an increase of approximately $10 million
over the prior year, due primarily to the acquisition of State Industries. We
expect the level of 2002 capital expenditures to be marginally lower than 2002
depreciation expense and that cash flow during 2002 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 2002.

Our long-term debt decreased by $11.5 million from $390.4 million at December
31, 2001 to $378.9 million at March 31, 2002. Our leverage as measured by the
ratio of total debt to total capitalization was 45.7 percent, down slightly from
the end of 2001. Excluding potential acquisitions and assuming current
outstanding share levels, we expect 2002 cash flow to result in a year-end
leverage ratio of approximately 43%, closer to our long-term target of 40%. We
did not enter into any significant operating leases during the first quarter of
2002. We expect to have adequate liquidity in 2002 as we have a minimal amount
of long-term debt maturing, and we have adequate credit facilities to support
our short-term borrowing needs. At March 31, 2002, our company had available
borrowing capacity of $92.2 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 State Industries in December of 2001, we
recorded additional purchase liabilities of approximately $3.9 million
associated with employee severance costs. As of March 31, 2002, we have charged
$0.6 million against this reserve. In addition, we recorded purchase liabilities
of $17.9 million in 1999 associated with our MagneTek motor acquisition, which
included employee severance and relocation, as well as certain facility costs.
The balance of the MagneTek purchase liabilities was $6.0 million at March 31,
2002. We expect these activities to be completed within the next year.

On April 9, 2002, our board of directors declared a regular quarterly dividend
of $.13 per share on our Common stock and Class A common stock, which is payable
on May 15, 2002 to stockholders of record on April 30, 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.
