LITTELFUSE, INC. NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) 1. BASIS OF PRESENTATION The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information. Accordingly, they do not include all of the information and notes required by accounting principles generally accepted in the United States 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 period ended April 3, 2004, are not necessarily indicative of the results that may be expected for the year ending January 1, 2005. For further information, refer to the Company's consolidated financial statements and the notes thereto incorporated by reference in the Company's Annual Report on Form 10-K for the year ended January 3, 2004. 2. BUSINESS SEGMENT INFORMATION The Company designs, manufactures and sells circuit protection devices throughout the world. The Company has three reportable geographic segments: The Americas, Europe and Asia-Pacific. The circuit protection market in these geographical segments is categorized into three major product areas: electronic, automotive and electrical. The Company evaluates the performance of each geographic segment based on its net income or loss. The Company also accounts for intersegment sales as if the sales were to third parties. The Company's reportable segments are the business units where the revenue is earned and expenses are incurred. The Company has subsidiaries in The Americas, Europe and Asia-Pacific where each region is measured based on its sales and operating income or loss. Information concerning the operations in these geographic segments for the periods ended April 3, 2004, and March 29, 2003, is as follows (in thousands): Three Months Three Months Ended April 3, Ended March 29, 2004 2003 - --------------------------------------------------------------------- REVENUES The Americas 53,177 34,696 Europe 20,903 13,341 Asia-Pacific 37,338 21,925 Combined Total 111,418 69,962 Corporate - - Consolidated Total 111,418 69,962 6

INVENTORIES The components of inventories are as follows (in thousands): April 3, January 3, 2004 2004 -------- ------- Raw material $11,747 $11,783 Work in process 19,975 16,224 Finished goods 22,708 24,591 ------- ------- Total $54,430 $52,598 ======= ======= 4. LONG-TERM OBLIGATIONS Total debt at the end of the first quarter 2004 totaled $28.8 million and consisted of the following: (1) 6.16% private placement notes totaling $20.0 million, (2) foreign revolver borrowings totaling $8.5 million, and (3) notes payable relating to mortgages totaling $0.3 million. Of this indebtedness, $18.7 million is considered to be current liabilities. The Company has a $50.0 million, three-year revolving bank credit agreement that expires on August 26, 2006. The bank credit agreement is subject to a maximum indebtedness calculation and other financial covenants. No revolver principal payments are required until the agreement matures. At April 3, 2004, the Company had available $50.0 million of borrowing capability under the revolving bank credit agreement. The revolving bank credit agreement has an interest rate of prime or LIBOR plus 0.875%. 8

5. PER SHARE DATA Net income per share amounts for the three months ended April 3, 2004, and March 29, 2003, are based on the weighted average number of common and common equivalent shares outstanding during the periods as follows (in thousands, except per share data): Three months ended April 3, March 29, 2004 2003 ------- -------- Average shares outstanding 22,032 21,771 Net effect of dilutive stock options and restricted shares - Diluted 356 50 ------- ------- Average shares outstanding - Basic 22,032 21,771 ======= ======= - Diluted 22,388 21,821 ======= ======= Net income $ 9,606 $ 3,223 ======= ======= Net income per share - Basic $ 0.44 $ 0.15 ======= ======= - Diluted $ 0.43 $ 0.15 ======= ======= Options to purchase 252,204 shares of common stock at exercise prices ranging from $34.13 to $35.50 and options to purchase 1,692,105 shares of common stock at exercise prices ranging from $17.82 to $35.50 were outstanding at April 3, 2004, and March 29, 2003, respectively, but were not included in the computation of diluted earnings per share because the options' exercise prices were greater than the average market price of the common shares and, therefore, the options would have no dilutive effect. 6. TECCOR ACQUISITION On July 7, 2003, the Company completed the acquisition of all of the outstanding stock of Teccor Electronics, Inc., a subsidiary of Invensys plc (`Teccor') for $44.6 million in cash, plus a future payment of $5.0 million contingent on sales of Teccor products reaching $107.0 million for calendar year 2005. Teccor manufactures semiconductor products for the telecommunications and industrial market segments, including transient voltage suppression devices and power switching devices. The addition of Teccor's transient voltage suppression products expands the Company's line of overvoltage products and strengthens its position in the telecom and industrial market segments. The acquisition was accounted for using the purchase method and the operations of Teccor are included in the Company's operations from the date of acquisition. The allocation of the purchase price resulted in no goodwill. 9

The acquisition was funded with cash on hand and borrowings under the Company's $50.0 million revolving credit facility. Purchase price allocation, net of cash (in thousands) Current assets $27,508 Property, plant and equipment 21,550 Intangible asset 6,100 Deferred tax assets 6,703 Current liabilities (9,985) Purchase accounting liabilities (6,900) Other long-term liabilities (386) ------- Total purchase price, net of cash $44,590 ======= In connection with the acquisition of Teccor Electronics and at the time of the acquisition, the Company recorded purchase accounting liabilities of $6.9 million primarily for redundancy costs related to manufacturing operations and selling, general and administrative functions. Included in this amount is $0.7 million to reflect the obligation of Teccor to remit proceeds from the sale of land to the former owners. As of April 3, 2004, changes to the purchase accounting liability include a $4.4 million payment related to employee severance, a $1.6 million reserve adjustment and a $0.7 million payment to remit proceeds from the sale of land to the former owners, leaving a purchase accounting restructuring liability balance of $0.2 million at April 3, 2004. The remaining accrued liabilities are expected to be paid by the end of the 2004 fiscal year. The following unaudited pro forma consolidated financial information for the Company has been prepared assuming the acquisition had occurred on the first day of the respective period. (in thousands, except for share data) Three Months Ended March 29, 2003 (unaudited) -------- Net sales $ 87,405 Operating loss (75) Net loss (849) Diluted net loss per share $ (0.04) -------- 10

The unaudited pro forma financial information above reflects the following pro forma adjustments: (a) Additional depreciation expense related to the $19.3 million write-up to record fixed assets at fair value; (b) Reduction of sales, general and administrative expense adjustments based on forward-looking estimates to eliminate Invensys expense allocations that are not expected to be incurred after the acquisition; and (c) Adjustment for additional interest expense related to the $16,000,000 borrowing under the Company's line of credit to help fund the acquisition. These unaudited pro forma results are presented for comparative purposes only. The pro forma results are not necessarily indicative of what actual results would have been had the acquisition been completed as of the beginning of the respective period, or of future results. 7. DERIVATIVES AND HEDGING On June 11, 2002, the Company entered into cross currency rate swaps, with a notional amount of $11.6 million, as a cash flow hedge against the variability of Yen cash flows attributable to the exchange rate risk on forecasted intercompany sales of inventory to a Japanese subsidiary. The cross currency rate swaps convert a portion of the Company's US Dollar fixed rate debt to fixed rate Japanese Yen debt. The swap agreements were accounted for as a cash flow hedge and reported at fair value. The notional amount outstanding at April 3, 2004, was $6.0 million and the fair value of the outstanding cross currency rate swap agreements was recognized as a $1.1 million liability and as a charge to comprehensive loss in the Consolidated Balance Sheet at April 3, 2004. Derivative financial instruments involve, to a varying degree, elements of market and credit risk not recognized in the consolidated financial statements. The market risk associated with these instruments resulting from interest rate movements is expected to offset the market risk of the underlying transactions being hedged. The counterparties to the agreements relating to the Company's cross currency rate instruments consist of major international financial institutions with high credit ratings. The Company does not believe that there is significant risk of non-performance by these counterparties because the Company monitors the credit ratings of such counterparties, and limits the financial exposure and amount of agreements entered into with any one financial institution. While the notional amount of the derivative financial instruments provide one measure of the volume of these transactions, they do not represent the amount of the Company's exposure to credit risk. The amounts potentially subject to credit risk (arising from the possible inability of counterparties to meet the terms of their contracts) are generally limited to the amounts, if any, by which the counterparties' obligations under the contracts exceed the obligations of the Company to the counterparty. 11

8. PENSIONS The components of net periodic benefit cost for the first quarter of 2004 as compared with the first quarter of 2003 were: U.S. Pension Benefits Foreign Plans ---------------------- ---------------- 2004 2003 2004 2003 ----- ------ ---- ---- Service cost $ 737 $ 667 $ 281 $ 249 Interest cost 882 888 372 315 Expected return on plan assets (907) (916) (384) (311) Amortization of prior service cost 3 3 (3) (3) Amortization of transition asset - - (23) (26) Amortization of net (gain) loss 48 28 52 - Recognized actuarial loss - - - 63 ------------------------------------------------ Total cost of the plan 763 670 295 287 Expected plan participants' contribution - - - (52) ------------------------------------------------ Net periodic benefit cost $ 763 $ 670 $ 295 $ 235 ------------------------------------------------ The expected rate of return on pension plan assets is 8.75% in 2004 and 2003. 9. COMPREHENSIVE INCOME Total comprehensive income for the three months ended April 3, 2004, and March 29, 2003, was approximately $9.3 and $3.5 million, respectively. The adjustment for comprehensive income consists of deferred gains and losses from foreign currency translation adjustments and qualified cash flow hedges and unrealized gains and losses on available-for-sale securities. 10. STOCK-BASED COMPENSATION The following table discloses our pro forma net income and diluted net income per share had the valuation methods under SFAS 123 been used for our stock option grants. The table also discloses the weighted average assumptions used in estimating the fair value using the Black-Scholes option pricing model. Amounts for the first quarter of 2004 as compared with the first quarter of 2003 were: (In thousands, except per share amounts) 2004 2003 --------- ------ Net income as reported $ 9,606 $3,223 Stock option compensation expense, net of tax (284) (262) --------- ------ Pro forma net income $ 9,321 $2,961 Basic net income per share As reported $ 0.44 $ 0.15 Pro forma $ 0.42 $ 0.14 Diluted net income per share As reported $ 0.43 $ 0.15 Pro forma $ 0.42 $ 0.14 12

Risk-free interest rate 3.55% 3.72% Expected dividend yield 0% 0% Expected stock price volatility 49.6% 45.7% Expected life of options 8 years 8 years These pro forma amounts may not be representative of future disclosures because the estimated fair value of the options is amortized to expense over the vesting period and additional options may be granted in the future. 11. NEW ACCOUNTING STANDARDS In December 2003, the FASB issued revised Statement No. 132 (SFAS 132). "Employers' Disclosures about Pensions and Other Postretirement Benefits." The revised SFAS 132 requires additional disclosures about the plan obligations and components of net periodic benefit cost recognized during interim periods. This Statement is effective for financial statements with fiscal years ending after December 15, 2003 and interim periods beginning after December 15, 2003. The Company adopted the interim disclosure requirements effective January 1, 2004. The adoption did not have any impact on the Company's financial position or results of operations. 12. SUBSEQUENT EVENT On May 6, 2004, the Company entered into a definitive agreement to acquire an 82% stake in Heinrich Industrie AG for (euro)39.5 million (approximately $47.2 million) in cash. Pursuant to this agreement, the Company purchased the controlling interest in Heinrich Industrie from the company's two largest shareholders. The Company also intends to promptly initiate a tender offer for the remaining shares of this publicly held company. The transaction will be financed through cash on hand and use of the Company's existing credit facility. 13

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations Sales by Market and Geography (Dollars in millions) FIRST QUARTER ------------------------------------ 2004 2003 % CHANGE -------- -------- -------- MARKET Electronics $ 50.1 $ 37.2 35% Automotive 28.2 24.6 15% Electrical 8.7 8.2 6% -------- -------- -- Subtotal 87.0 70.0 24% Teccor 24.4 - - -------- -------- -- TOTAL $ 111.4 $ 70.0 59% ======== ======== == FIRST QUARTER ------------------------------------ 2004 2003 % CHANGE -------- -------- -------- GEOGRAPHY Americas $ 53.2 $ 34.7 53% Europe 20.9 13.3 57% Asia Pacific 37.3 22.0 70% -------- -------- -- TOTAL $ 111.4 $ 70.0 59% ======== ======== == RESULTS OF OPERATIONS First Quarter, 2004 Sales for the first quarter 2004 increased 59% or $41.4 million to $111.4 million, compared to $70.0 million in the first quarter of 2003. The increase was driven by sales of $24.4 million from Teccor, which was acquired July 7, 2003. Excluding Teccor, sales for the first quarter 2004 increased 24% compared to the first quarter of 2003. On a geographic basis, sales in the Americas increased $18.5 million or 53% in the first quarter of 2004, as Teccor added $11.6 million for the quarter. Excluding Teccor, sales in the Americas increased $6.9 million or 19.9%, due to strengthening automotive, electronic and electrical markets compared to last year. Europe sales increased $7.6 million or 57% in the first quarter of 2004 as Teccor added $4.3 million and favorable currency added $2.3 million. Asia sales increased $15.3 million or 70% compared to the prior year first quarter, due to $8.5 million of sales from Teccor, favorable currency effects of $0.9 million and strengthening Asian demand for digital consumer products. 14

Electronic sales increased $37.3 million or 100% to $74.5 million in the first quarter of 2004 from $37.2 million in the same quarter of last year with $24.4 million of the increase due to Teccor. Excluding Teccor, electronic sales increased $12.9 million or 35% to $50.1 million compared to $37.2 million in the prior year quarter. Electronic sales increased in the Asia region, primarily due to increased demand for consumer electronics, notebook computers and handheld products. The electronic markets in North America and Europe also improved compared to the same period in the prior year due primarily to recoveries in the telecom and industrial markets. Automotive sales increased $3.6 million or 15% to $28.2 million in the first quarter of 2004 compared to $24.6 million in the same quarter last year. North America automotive sales were favorably impacted by product sold to a large OEM customer in support of a recall program and Europe automotive sales benefited from favorable currency effects. Electrical fuse sales increased $0.5 million or 6% to $8.7 million in the first quarter 2004 from $8.2 million in the same quarter last year. The electrical fuse market has begun to show signs of improvement as industrial markets begin to recover. The other key market, non-residential construction, remains weak. Gross margin was $39.8 million or 35.7% of sales for the first quarter of 2004 compared to $23.1 million or 33.0% in the same quarter last year. The increase in gross margin as a percent of sales was due to progress related to the Teccor integration, operating leverage resulting from higher sales, cost reductions in excess of price erosion and favorable currency effects. Total operating expenses were $24.1 million or 21.6% of sales for the first quarter of 2004 compared to $17.8 million or 25.5% of sales for the same quarter last year. The reduction in operating expenses as a percent of sales reflects improved expense leverage resulting from the Teccor acquisition. Operating income increased to $15.7 million or 14.1% of sales in the first quarter of 2004 compared to $5.2 million or 7.5% in the prior year. Operating income increased due to higher sales, increased gross margin and reduced operating expenses as a percent of sales as explained above. Interest expense was $0.4 million in the first quarter of this year compared to $0.5 million in the first quarter of last year due to lower debt levels. Other expense was $0.3 million for the first quarter of 2004 compared to other income of $0.3 million in the first quarter of the prior year. The prior year includes a $0.2 million gain related to the sale of a Korean manufacturing site. Income before income taxes was $15.0 million for the first quarter 2004 compared to $5.0 million for the first quarter of 2003. Income taxes were $5.4 million with an effective tax rate of 36% for the first quarter of 2004 compared to $1.8 million with an effective tax rate of 36% in the first quarter of last year. Net income increased to $9.6 million in the first quarter this year compared to $3.2 million in the first quarter of last year and diluted earnings per share increased to $0.43 in the first quarter this year compared to $0.15 per diluted share in the same quarter last year. 15

LIQUIDITY AND CAPITAL RESOURCES Assuming no material adverse changes in market conditions , management expects that the Company will have sufficient cash from operations to support both its operations and its current debt obligations for the foreseeable future. Littelfuse started the 2004 year with $22.1 million of cash. Net cash provided by operations was $2.9 million for the first three months. Net cash used in investing activities included $3.0 million in purchases of property, plant and equipment. In addition, net cash provided by financing activities included stock option exercises of $1.9 million. The net cash provided by operations, less investing and financing activities, resulted in a $1.8 million net increase in cash. This left the Company with a cash balance of $23.9 million at April 3, 2004. The ratio of current assets to current liabilities was 2.0 to 1 at the end of the first quarter 2004 compared to 1.8 to 1 at year-end 2003 and 2.4 to 1 at the end of the first quarter 2003. The days sales in receivables was approximately 49 days at the end of the first quarter 2004, compared to 50 days at year-end 2003, and 56 days at the end of the first quarter 2003. The days inventory outstanding was approximately 69 days at the end of the first quarter 2004 compared to 71 days at year-end 2003 and 91 days at end of the first quarter 2003. The Company's net capital expenditures were $3.0 million for the first quarter 2004. Included in this amount were expenditures for plant expansions in China and equipment related to capacity increases and cost reduction. Total debt at the end of the first quarter 2004 totaled $28.8 million and consisted of the following: (1) 6.16% private placement notes totaling $20.0 million, (2) foreign revolver borrowings totaling $8.5 million, and (3) notes payable relating to mortgages totaling $0.3 million. Of this indebtedness, $18.7 million is considered to be current liabilities. The Company has a $50.0 million in the U.S., of which $50.0 million was available at April 3, 2004. The revolving bank credit agreement has an interest rate of prime or LIBOR plus 0.875%. The Company also had $1.9 million in letters of credit outstanding at April 3, 2004. OUTLOOK Sales in 2004 are expected to improve slightly in the automotive and electrical markets. Sales in the electronics market are expected to show steady growth, particularly in Asian markets. As these markets improve, the Company believes its long-term growth strategy, which emphasizes development of new circuit protection products and providing customers with solutions and technical support in all major regions of the world, will drive sales growth in all of its markets. The Company will initiate a new series of projects in 2004 to consolidate and reduce costs in its global manufacturing and distribution operations. These programs are expected to generate sufficient cost savings to more than offset price erosion in 2004. The Company also plans to increase research and development spending to accelerate new product development in order to help drive future sales growth. The benefits of incremental volume improvements and cost savings are expected to continue to have a favorable impact on earnings in 2004. 16

The Company is working to expand its market share in the overvoltage circuit protection market with the addition of products and technology through the Semitron Industries, Harris Suppression Products, Teccor and Heinrich Industrie AG acquisitions and the ability to offer customers total circuit protection solutions. The Company remains committed to investing in new product development and technical resources to provide customers with overcurrent and overvoltage circuit protection solutions and expertise.

This report should be read in conjunction with information provided in the financial statements appearing in the Company's Annual Report on Form 10-K for the year ended January 3, 2004. ITEM 3. QUALITATIVE AND QUANTITATIVE DISCLOSURES ABOUT MARKET RISK The Company is exposed to market risk from changes in foreign exchange rates, commodities and to a lesser extent, interest rates. The Company had long-term debt outstanding at April 3, 2004, in the form of fixed rate private placement notes, a U. S. variable rate revolving line of credit and foreign lines of credit at variable interest rates. Approximately 69% of the Company's long-term debt is at fixed rates and primarily consists of bank loans and mortgages. The Company does not enter into derivative transactions (i.e., interest rate swaps) with respect to its long-term debt, as the current interest expense on this debt is not deemed material to operations. A portion of the Company's operations consists of manufacturing and sales activities in foreign countries. The Company has manufacturing facilities in Mexico, England, Ireland, Switzerland, China and the Philippines. Substantially all sales in Europe are denominated in British Pounds Sterling, United States Dollars and Euros and substantially all sales in the Asia-Pacific region are denominated in United States Dollars, Japanese Yen and South Korean Won. The Company's identifiable foreign exchange exposures result from the purchase and sale of products from affiliates, repayment of intercompany trade and loan amounts and translation of local currency amounts in consolidation of financial results. Changes in foreign currency exchange rates or weak economic conditions in the foreign countries in which it manufactures and distributes products could affect the Company's sales and financial results. The Company primarily utilizes 17

netting and offsets to reduce known foreign currency exposures and, when appropriate, derivative instruments as hedges of specific foreign currency cash flows. The Company has entered into cross currency rate swaps with a notional amount of $11.6 million. The cross currency swaps convert $11.6 million of the Company's fixed rate 6.16% U.S. Dollar debt to fixed rate 3.13% Japanese Yen debt. The fair value of the rate swap agreements outstanding at April 3, 2004, which had a notional amount of $6.0 million, was recognized as a $1.1 million liability, and is reported in consolidated shareholders' equity as a component of other comprehensive income. A risk management policy has been implemented by the Company that describes the procedures and controls over derivative financial instruments. Under the policy, the Company does not use derivative financial instruments for trading purposes and the use of such instruments is subject to the approval of senior officers. Typically, the use of such derivative instruments is limited to hedging activities related to specific foreign currency cash flows. The Company's exposure related to such transactions is, in the aggregate, not material to the Company's financial position, results of operations and cash flows. The Company uses various metals in the production of its products, including zinc, copper and silver. The Company's earnings are exposed to fluctuations in the prices of these commodities. The Company does not currently use derivative financial instruments to mitigate this commodity price risk. ITEM 4. CONTROLS AND PROCEDURES As of April 3, 2004, the Chief Executive Officer and Chief Financial Officer of the Company evaluated the effectiveness of the disclosure controls and procedures of the Company and concluded that these disclosure controls and procedures are effective to ensure that material information relating to the Company and its consolidated subsidiaries has been made known to them by the employees of the Company and its consolidated subsidiaries during the period preceding the filing of this Report. There were no significant changes in the Company's internal controls or in other factors that could significantly affect these controls subsequent to the last day they were evaluated by our Chief Executive Officer and Chief Financial Officer.
