5 NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) A. Basis of Presentation The unaudited financial statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) and, in the opinion of the Company, include all adjustments, consisting only of normal recurring items, necessary for a fair statement of results for each period. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to such SEC rules and regulations. The Company believes that the disclosures made are adequate to make the information presented not misleading. It is suggested that these financial statements be read in conjunction with financial statements and the notes thereto included in the Company's latest Annual Report. The year end condensed balance sheet data was derived from audited financial statements but does not include all disclosures required by generally accepted accounting principles. Certain amounts in the prior year financial statements have been reclassified to conform to the current year presentation. B. Inventory The major classes of inventories were as follows (in thousands): September 30, June 30 2002 2002 ---------- --------- Inventories: Finished parts $34,426 $35,485 Work in process 6,645 5,668 Raw materials 4,116 3,351 ------- ------- $45,187 $44,504 ------- ------- ------- ------- C. Debt At September 30, 2002, the Company had debt, excluding the short-term notes payable, consisting of $10 million borrowed under a $20 million revolving line of credit facility and $11.4 million of senior notes with a final maturity of June 2006. Both loan agreements require compliance with certain restrictive covenants including a specified ratio of earnings to fixed charges (fixed charge coverage ratio). Compliance is determined quarterly based on the trailing four quarters ending on each determination date. For the four quarters ending September 30, 2002, the Company was not in compliance with the fixed charge coverage ratio primarily due to operating losses incurred in the most recently completed quarter. The Company is currently in discussions with the senior note holder to obtain a waiver and amend future covenants. Until the waiver and amendment are obtained, the Company has reflected the entire $11.4 million as a current liability. The violation under the line of credit has been waived and a new facility is being negotiated to provide a $20 million, three-year revolving line of credit. An interim facility for up to $12 million with a final maturity of October 31, 2003 is in place pending completion of those negotiations.

6 D. Contingencies The Company is involved in various stages of investigation relative to hazardous waste sites, two of which are on the United States EPA National Priorities List (Superfund sites). The Company's assigned responsibility at each of the Superfund sites is less than 3%. The Company has also been requested to provide administrative information related to two other potential Superfund sites but has not yet been identified as a potentially responsible party. Additionally, the Company is subject to certain product liability matters in the normal course of business. At September 30, 2002 the Company has accrued approximately $632,000, which represents management's best estimate available for possible losses related to these contingencies. This amount has been provided over the past several years. Based on the information available, the Company does not expect that any unrecorded liability related to these matters would materially affect the consolidated financial position, results of operations or cash flows. E. BUSINESS SEGMENTS Information about the Company's segments is summarized as follows (in thousands): September 30, September 30, 2002 2001 ------------- ------------- Manufacturing segment sales $ 30,464 $ 34,758 Distribution segment sales 13,849 14,135 Inter/Intra segment sales (7,792) (8,262) --------- --------- Net sales $ 36,521 $ 40,631 --------- --------- --------- --------- Manufacturing segment earnings $ (2,477) $ 113 Distribution segment earnings 455 1,019 Inter/Intra segment loss (634) (617) --------- --------- Earnings before income taxes and minority interest $ (2,656) $ 515 --------- --------- --------- --------- Assets September 30, June 30, 2002 2002 ------------- ------------ Manufacturing segment assets $ 137,380 $ 139,810 Distribution segment assets 28,978 30,275 Corporate assets and elimination of inter-company assets (9,557) (12,805) -------- -------- $ 156,801 $ 157,280 -------- -------- -------- --------

7 F. RECENTLY ISSUED ACCOUNTING STANDARDS The Company adopted Statement of Financial Accounting Standards (SFAS) No. 143, Accounting for Obligations Associated with the Retirement of Long-Lived Assets and SFAS No. 144, Accounting for the Impairment or Disposal of Long- Lived Assets as of the beginning of the fiscal year. On review, it was determined that there were no asset retirement obligations or impairment of these assets and thus no losses were recorded in the first fiscal quarter or anticipated for the fiscal year. In April 2002, the FASB issued SFAS No. 145, "Recission of FASB Statements No. 4, 44, and 64, Amendment of FASB Statement No. 13, and Technical Corrections," related to accounting for debt extinguishments, leases, and intangible assets of motor carriers. The provisions of SFAS No. 145 are effective for the Company on July 1, 2002, however the adoption of this Statement did not have a significant impact on the Company's results of operations or its financial position. In June 2002, the FASB issued SFAS No. 146, "Accounting for Costs Associated with Exit or Disposal Activities." This Statement addresses financial accounting and reporting for costs associated with exit or disposal activities and nullifies Emerging Issues Task Force (EITF) Issue No. 94-3, "Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred in a Restructuring)." The provisions of this Statement are effective for exit or disposal activities that are initiated after December 31, 2002, accordingly management anticipates that the adoption of SFAS No. 146 will not have a significant effect on the Company's results of operations or its financial position.

8 Item 2. MANAGEMENT DISCUSSION AND ANALYSIS Net revenues for the first fiscal quarter were 10 percent below year-ago levels due to weak market demand and supplier quality problems at the domestic manufacturing operation. As a result, the Company incurred a net loss of $1.7 million versus modest profit reported in last year's first fiscal quarter. The primary reasons for the poor results - reduced sales volume and the additional manufacturing cost incurred - stem from the aforementioned quality issues, discussed in greater detail below. The general weakness in global economic activity experienced in the last six months of fiscal 2002 continued into the first quarter of fiscal 2003. Almost all of our operations have been affected by the worldwide slowdown. The weakness in pleasure craft activity continues to be the largest single factor adversely affecting sales and that impact was felt most by our Belgian manufacturing operation. Sales from our domestic manufacturing plants dropped due primarily to non-conforming parts received from two of our key subcontract suppliers early in the period. Resolution of those problems resulted in reduced production efficiency and delayed shipments, primarily of marine and powershift transmission products. Sales of Arneson surface drives, for which demand has remained relatively stable, were slightly above those reported a year ago. On the other hand, shipments of industrial products and marine transmissions for commercial boats were well off the pace of the first quarter last year. With few exceptions, sales from our distribution subsidiaries throughout the world were lower than in the comparable period last year. The reduction in profitability from last year's first quarter was traceable mainly to a decline in the gross margin. The supplier quality problem cited earlier added approximately $0.7 million of direct cost to the domestic manufacturing operation. At least as important, however, were the production hours lost and the disruption of workflows that were necessary to serve the critical delivery requirements of our customers. Claims against the vendors to recover some of the losses will be recorded as an offset when they are received, but the impact of that recovery is not expected to be significant in any one quarter. The flow of high-quality production parts has been restored, and we expect to reduce our past-due backlog and return to normal shipping schedules during the second fiscal quarter. Marketing, engineering, and administrative (ME&A) expenses increased by six percent from last year's first fiscal quarter with the majority of the increase due to engineering development of the new marine transmission line. With slightly lower interest rates and debt dropping by about 25 percent from a year ago, interest expense continued to decline. The average income tax rate was lower than a year ago due to a greater proportion of domestic losses incurred versus overseas earnings, which are taxed at a higher rate. The Company adopted Statement of Financial Accounting Standards (SFAS) No. 143, Accounting for Obligations Associated with the Retirement of Long-Lived Assets and SFAS No. 144, Accounting for the Impairment or Disposal of Long- Lived Assets as of the beginning of the fiscal year. On review, it was determined that there were no asset retirement obligations or impairment of these assets and thus no losses were recorded in the first fiscal quarter or anticipated for the fiscal year.

9 Financial Condition, Liquidity and Capital Resources Working capital and the current ratio closely approximated those of the previous quarter-end. Reduced sales volume was accompanied by a decline in accounts receivable of $2 million, which was about equal to the total net cash flows from operations. That cash flow provided for our financing and investing needs and an increase in the cash balance. The Company=s balance sheet is strong, there are no off-balance-sheet arrangements, and we continue to have sufficient liquidity for near-term needs. At September 30, 2002, the Company had debt, excluding the short-term notes payable, consisting of $10 million borrowed under a $20 million revolving line of credit facility and $11.4 million of senior notes with a final maturity of June 2006. Both loan agreements require compliance with certain restrictive covenants including a specified ratio of earnings to fixed charges (fixed charge coverage ratio). Compliance is determined quarterly based on the trailing four quarters ending on each determination date. For the four quarters ending September 30, 2002, the Company was not in compliance with the fixed charge coverage ratio primarily due to operating losses incurred in the most recently completed quarter. The Company is currently in discussions with the senior note holder to obtain a waiver and amend future covenants. Until the waiver and amendment are obtained, the Company has reflected the entire $11.4 million as a current liability. The violation under the line of credit has been waived and a new facility is being negotiated to provide a $20 million, three-year revolving line of credit. An interim facility for up to $12 million with a final maturity of October 31, 2003 is in place pending completion of those negotiations. The Company has obligations under non-cancellable operating lease contracts and a senior note agreement for certain future payments. A summary of those commitments follows (in thousands): Contractual Obligations Total Less than 1-3 4-5 After 5 1 year Years Years Years Short-term debt $ 1,998 $ 1,998 Current maturities on Long-term debt $11,397 $11,397 Revolver borrowing $10,000 $10,000 Long-term debt $ 45 $ 45 Operating leases $ 7,890 $ 2,605 $ 2,981 $ 1,152 $ 1,152 Total obligations $31,330 $16,000 $13,026 $ 1,152 $ 1,152

10 New Accounting Releases In April 2002, the FASB issued SFAS No. 145, "Recission of FASB Statements No. 4, 44, and 64, Amendment of FASB Statement No. 13, and Technical Corrections," related to accounting for debt extinguishments, leases, and intangible assets of motor carriers. The provisions of SFAS No. 145 are effective for the Company on July 1, 2002, however the adoption of this Statement did not have a significant impact on the Company's results of operations or its financial position. In June 2002, the FASB issued SFAS No. 146, "Accounting for Costs Associated with Exit or Disposal Activities." This Statement addresses financial accounting and reporting for costs associated with exit or disposal activities and nullifies Emerging Issues Task Force (EITF) Issue No. 94-3, "Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred in a Restructuring)." The provisions of this Statement are effective for exit or disposal activities that are initiated after December 31, 2002, accordingly management anticipates that the adoption of SFAS No. 146 will not have a significant effect on the Company's results of operations or its financial position. Critical Accounting Policies The preparation of this Quarterly Report requires management's judgment to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the dates of the financial statements, and the reported amounts of revenues and expenses during the reporting period. There can be no assurance that actual results will not differ from those estimates. Twin Disc's significant and critical accounting policies are described in Note A in the Notes to Consolidated Financial Statements and Management Discussion and Analysis, respectively, in the Annual Report for June 30, 2002. There have been no significant changes to those accounting policies subsequent to June 30, 2002. Item 3. Quantitative and Qualitative Disclosure About Market Risk. The Company is exposed to market risks from changes in interest rates, commodities and foreign exchange. To reduce such risks, the Company selectively uses financial instruments and other pro-active management techniques. All hedging transactions are authorized and executed pursuant to clearly defined policies and procedures, which prohibit the use of financial instruments for trading or speculative purposes. Interest rate risk - The Company=s earnings exposure related to adverse movements of interest rates is primarily derived from outstanding floating rate debt instruments that are indexed to the prime and LIBOR interest rates. Those debt facilities bear interest predominantly at the prime interest rate minus .5% or LIBOR plus 1%. Due to the relative stability of interest rates, the Company did not utilize any financial instruments at September 30, 2002 to manage interest rate risk exposure. A 10 percent increase or decrease in the applicable interest rate would result in a change in pretax interest expense of approximately $30,000.

11 Commodity price risk - The Company is exposed to fluctuation in market prices for such commodities as steel and aluminum. Due to the relative stability of these commodities, the Company does not utilize commodity price hedges to manage commodity price risk exposure. Currency risk - The Company has exposure to foreign currency exchange fluctuations. Approximately one-third of the Company=s revenues in the three months ended September 30, 2002 and 2001 were denominated in currencies other than the U.S. dollar. Of that total, approximately two-thirds was denominated in euros with the balance composed of Japanese yen and the Australian and Singapore dollars. The Company does not hedge the translation exposure represented by the net assets of its foreign subsidiaries. Foreign currency translation adjustments are recorded as a component of shareholders= equity. Forward foreign exchange contracts are used to hedge the currency fluctuations on significant transactions denominated in foreign currencies. Derivative Financial Instruments - The Company has written policies and procedures that place all financial instruments under the direction of the company corporate treasury and restrict derivative transactions to those intended for hedging purposes. The use of financial instruments for trading purposes is prohibited. The Company uses financial instruments to manage the market risk from changes in foreign exchange rates. The Company primarily enters into forward exchange contracts to reduce the earnings and cash flow impact of non-functional currency denominated receivables and payables. These contracts are highly effective in hedging the cash flows attributable to changes in currency exchange rates. Gains and losses resulting from these contracts offset the foreign exchange gains or losses on the underlying assets and liabilities being hedged. The maturities of the forward exchange contracts generally coincide with the settlement dates of the related transactions. Gains and losses on these contracts are recorded in Other income (expense), net in the Consolidated Statement of Operations as the changes in the fair value of the contracts are recognized and generally offset the gains and losses on the hedged items in the same period. The primary currency to which the Company was exposed in 2002 and 2001 was the Euro. At September 30, 2002 the Company had net outstanding forward exchange contracts to purchase Euros in the value of $1,304,000 with a weighted average maturity of 28 days. The fair value of the Company=s contracts was approximately $0.0 million at September 30, 2002. At June 30, 2002 the Company had net outstanding forward exchange contracts to purchase Euros in the value of $2,053,000 with a weighted average maturity of 40 days. The fair value of the Company=s contracts was approximately $0.2 million at June 30, 2002. Item 4. Controls and Procedures. (a) Evaluation of Disclosure Controls and Procedures. As required by new Rules 13a-15 and 15d-15 of the Securities Exchange Act of 1934, within the 90-day period prior to the filing of this report and under the supervision and with the participation of management, including the Chief Executive Officer and the Chief Financial Officer, the Company has evaluated the effectiveness of the design and operation of its disclosure controls and procedures. Based on such evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that such disclosure controls and procedures are effective in ensuring that material information relating to the Company, including its consolidated subsidiaries, is made known to the certifying officers by others within the Company and its consolidated subsidiaries during the period covered by this report.

12 (b) Changes in Internal Controls. There were no significant changes in the Company's internal controls for financial reporting or in other factors that could significantly affect such internal controls subsequent to the date of such evaluation. However, in connection with the new rules, the Company has been engaged in the process of further reviewing and documenting its disclosure controls and procedures, including its internal accounting controls. The Company may from time to time make changes aimed at enhancing the effectiveness of its disclosure controls and procedures, including its internal controls, to ensure that the Company's systems evolve with its business.

13 Part II. OTHER INFORMATION Item 1. Legal Proceedings. Twin Disc is a defendant in several product liability or related claims considered either adequately covered by appropriate liability insurance or involving amounts not deemed material to the business or financial condition of the Company. Item 2. Changes in Securities and Use of Proceeds. There were no securities of the Company sold by the Company during the three months ended September 30, 2002, which were not registered under the Securities Act of 1933, in reliance upon an exemption from registration provided by Section 4 (2) of the Act. During the period covered by this report, the Company offered participants in the Twin Disc, Incorporated B The Accelerator 401(k) Savings Plan (the APlan@) the option to invest their Plan accounts in a fund comprised of Company stock. Participation interests of Plan participants in the Plan, which may be considered securities, were not registered with the SEC. During the fiscal year ended June 30, 2002, 68 Plan participants allocated an aggregate of $81,000 toward this investment option. Participant accounts in the Plan consist of a combination of employee deferrals, Company matching contributions, and, in some cases, additional Company profit-sharing contributions. No underwriters were involved in these transactions. On September 6, 2002, the Company filed a Form S-8 to register 100,000 shares of Company common stock offered through the Plan, as well as an indeterminate amount of Plan participation interests. Item 5. Other Information. The discussions in this report on Form 10-Q and in the documents incorporated herein by reference, and oral presentations made by or on behalf of the Company contain or may contain various forward-looking statements (particularly those referring to the expectations as to possible strategic alternatives, future business and/or operations, in the future tense, or using terms such as "believe", "anticipate", "expect" or "intend") that involve risks and uncertainties. The Company's actual future results could differ materially from those discussed, due to the factors which are noted in connection with the statements and other factors. The factors that could cause or contribute to such differences include, but are not limited to, those further described in the "Management's Discussion and Analysis". Item 6. Exhibits and Reports on Form 8-K. There were no reports on Form 8-K during the three months ended September 30, 2002.
