KOSS CORPORATION AND SUBSIDIARIES March 31, 2003 NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS 1. CONDENSED CONSOLIDATED FINANCIAL STATEMENTS The financial statements presented herein are based on interim amounts. In the opinion of management, all adjustments (consisting only of normal recurring accruals) necessary to present fairly the financial position, results of operations and cash flows at March 31, 2003 and for all periods presented have been made. The income from operations for the quarter ended March 31, 2003 is not necessarily indicative of the operating results for the full year. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted. It is suggested that these condensed consolidated financial statements be read in conjunction with the financial statements and notes thereto included in the Registrant's June 30, 2002, Annual Report on Form 10-K. 2. EARNINGS PER COMMON SHARE AND STOCK SPLIT Basic earnings per share are computed based on the weighted average number of common shares outstanding. The weighted average number of common shares outstanding for the quarters ending March 31, 2003 and 2002 were 3,625,431 and 3,648,054, respectively. For the nine months ended March 31, 2003 and 2002, weighted average number of common shares outstanding were 3,650,805 and 3,717,840, respectively. When dilutive, stock options are included as share equivalents using the treasury stock method. Common stock equivalents of 197,761 and 214,396 related to stock option grants were included in the computation of the average number of shares outstanding for diluted earnings per share for the quarters ended March 31, 2003 and 2002, respectively. Common stock equivalents of 185,781 and 228,595 related to stock option grants were included in the computation of the average number of shares outstanding for diluted earnings per share for the nine months ended March 31, 2003 and 2002, respectively. On October 2, 2001, the Company declared a 2 for 1 stock split of the Company's common stock for stockholders of record on October 22, 2001, with the effective date being November 5, 2001. Earnings per common share amounts disclosed have been restated to give effect to the common stock split. 3. INVENTORIES The classification of inventories is as follows:

March 31, 2003 June 30, 2002 -------------- ------------- Raw materials and work in process $ 1,990,195 $ 2,288,918 Finished goods 5,272,401 4,878,655 ----------- ----------- 7,262,596 7,167,573 LIFO reserve (787,361) (787,361) ----------- ----------- $ 6,475,235 $ 6,380,212 =========== ===========

4. STOCK PURCHASE AGREEMENT The Company has an agreement with its Chairman to repurchase Company common stock from his estate in the event of his death. The repurchase price is 95% of the fair market value of the common stock on the date that notice to repurchase is provided to the Company. The total number of shares to be repurchased shall be sufficient to provide proceeds which are the lesser of $2,500,000 or the amount of estate taxes and administrative expenses incurred by his estate. The Company is obligated to pay in cash 25% of the total amount due and to execute a promissory note at the prime rate of interest for the balance. The Company maintains a $1,150,000 life insurance policy to fund a substantial portion of this obligation. At March 31, 2003 and June 30, 2002, $1,490,000 has been classified as a Contingently Redeemable Equity Interest reflecting the estimated obligation in the event of execution of the agreement. 5. NEW ACCOUNTING PRONOUNCEMENTS In July 2001, the Financial Accounting Standards Board ("FASB") issued Statement of Financial Accounting Standards ("SFAS") No. 143, "Accounting for Asset Retirement Obligations" and in August 2001, issued SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets." SFAS No. 143 establishes accounting standards for the recognition and measurement of an asset retirement obligation. SFAS No. 144 addresses financial accounting and reporting for the impairment or disposal of long-lived assets, superseding SFAS No. 121. SFAS No. 143 and SFAS No. 144 were effective for the Company on July 1, 2002. The statements did not have an impact on the Company's results of operations or financial position. In June 2002, the FASB issued SFAS No. 146, "Accounting for Exit or Disposal Activities." This statement addresses the recognition, measurement, and reporting of costs associated with exit and disposal activities, including restructuring activities. The scope of the current statement also includes (1) costs related to a termination contract that is not a capital lease and (2) termination benefits that employees who are involuntarily terminated receive under the terms of a one-time benefit arrangement that is not an ongoing benefit arrangement or an individual deferred-compensation contract. SFAS No. 146 will be effective for exit or disposal activities that are initiated after December 31, 2002. The implementation of this issue did not have an impact on the Company's results of operations for the quarter ended March 31, 2003. In November 2002, the FASB issued FASB Interpretation No. 45, "Guarantor's Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees." This Interpretation elaborates on the disclosures to be made by a guarantor in its interim and annual financial statements about its obligations under certain guarantees that it has issued. It also clarifies that a guarantor is required to recognize, at the inception of a guarantee, a liability for the fair value of the obligation undertaken in issuing the guarantee. This Interpretation does not prescribe a specific approach for subsequently measuring the guarantor's recognized liability over the term of the related guarantee. This Interpretation also incorporates, without change, the guidance in FASB Interpretation No. 34, Disclosure of Indirect Guarantees of Indebtedness of Others, which is being superseded. The initial recognition and measurement provisions of this Interpretation are applicable on a prospective basis to guarantees issued or modified after December 31, 2002, irrespective of the guarantor's fiscal year-end. The disclosure requirements in this Interpretation are effective for financial statements of interim or annual periods ending after December 15, 2002. At March 31, 2003, the Company has issued no guarantees that qualify for disclosure in this interim financial statement. 7 of 18

In December 2002, the FASB issued SFAS No. 148, "Accounting for Stock-Based Compensation -- Transition and Disclosure, an amendment of FASB Statement No. 123." This Statement amends SFAS No. 123, "Accounting for Stock-Based Compensation," to provide alternative methods of transition for a voluntary change to the fair value based method of accounting for stock-based employee compensation. In addition, this Statement amends the disclosure requirements of SFAS No. 123 to require prominent disclosures in both annual and interim financial statements about the method of accounting for stock-based employee compensation and the effect of the method used on reported results. SFAS No. 148 will be effective for the Company on July 1, 2003. The Company is currently evaluating the impact of this statement on its results of operations. 6. DIVIDENDS DECLARED On March 24, 2003, the Company declared a quarterly cash dividend of $0.13 per share to be paid April 15, 2003 to stockholders of record on March 31, 2003. Such dividend payable has been recorded at March 31, 2003. 7. SUBSEQUENT EVENT On May 1, 2003, the Company acquired certain assets of ADDAX SOUND ("ADDAX") in exchange for 19,875 shares of common stock of the Company (value on May 1, 2003 of $313,628 based upon a closing per share price of $15.78) plus $100 in cash and assumed certain liabilities of ADDAX. ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS. Financial Condition, Liquidity and Capital Resources Cash provided by operating activities during the nine months ended March 31, 2003 amounted to $2,727,076. This was primarily a result of net income for the period offset by changes in operating assets and liabilities, primarily related to decreases in accounts receivable, accounts payable and income taxes payable. Capital expenditures for new property and equipment (including production tooling) were $569,663 for the nine months ending March 31, 2003. Budgeted capital expenditures for the fiscal year ending June 30, 2003 are $1,082,000. The Company expects to generate sufficient funds through operations to fund these expenditures. Stockholders' investment increased to $14,166,442 at March 31, 2003, from $13,272,746 at June 30, 2002. The increase reflects the effect of the exercise of stock options, purchase and retirement of common stock, offset by net income and dividends paid. The Company amended its existing credit facility in July 2002, extending the maturity date of the unsecured line of credit to November 1, 2003. This credit facility provides for borrowings up to a maximum of $10,000,000. The Company can use this credit facility for working capital purposes or for the purchase of its own common stock pursuant to the Company's common stock repurchase program. Borrowings under this credit facility bear interest at the bank's prime rate, or LIBOR plus 1.75%. This credit facility includes certain financial covenants that require the Company to maintain a minimum tangible net worth and specified current, interest coverage, and leverage ratios. The Company uses its credit facility from time to time, although there was no utilization of this credit facility at March 31, 2003 or June 30, 2002. 8 of 18

In April of 1995, the Board of Directors approved a stock repurchase program authorizing the Company to purchase from time to time up to $2,000,000 of its common stock for its own account. Subsequently, the Board of Directors periodically has approved increases in the stock repurchase program. The most recent increase was for an additional $2,000,000 in January of 2003, for a maximum of $37,500,000. The Company intends to effectuate all stock purchases either on the open market or through privately negotiated transactions, and intends to finance all stock purchases through its own cash flow or by borrowing for such purchases. For the nine months ended March 31, 2003, the Company purchased 37,500 shares of its common stock at a net price of $12.73 per share, for a total purchase price of $477,162. From the commencement of the Company's stock repurchase program through March 31, 2003, the Company has purchased a total of 4,914,180 shares for a total gross purchase price of $39,618,045 (representing an average gross purchase price of $8.06 per share) and a total net purchase price of $35,319,234 (representing an average net purchase price of $7.19 per share). The difference between the total gross purchase price and the total net purchase price is the result of the Company purchasing from certain employees shares of the Company's stock acquired by such employees pursuant to the Company's stock option program. In determining the dollar amount available for additional purchases under the stock repurchase program, the Company uses the total net purchase price paid by the Company for all stock purchases, as authorized by the Board of Directors. The Company also has an Employee Stock Ownership Plan and Trust ("ESOP") pursuant to which shares of the Company's stock are purchased by the ESOP for allocation to the accounts of ESOP participants. For the nine months ended March 31, 2003, the ESOP did not purchase any shares of the Company's stock. Results of Operations Net sales for the third quarter ended March 31, 2003 rose to $8,264,668 from $8,203,325 for the same period in 2002. Net sales for the nine months ended March 31, 2003 were down 7% at $25,038,494, compared with $26,906,133 during the nine months ended March 31, 2002. This decline was due to soft retail business through the second quarter partially offset by stronger retail sales in the third quarter. Gross profit as a percent of net sales remained generally consistent at 42% for the quarter ended March 31, 2003, compared to 42% for the same period in the prior year. For the nine month period ended March 31, 2003, the gross profit percentage was 41% compared to 40% for the same period in 2002. Selling, general and administrative expenses for the quarter ended March 31, 2003 were $1,935,499, or 23% of net sales, compared to $1,641,877 or 20% of net sales for the same period in 2002. For the nine month period ended March 31, 2003, these expenses were $5,549,294 or 22% of net sales, compared to $5,805,775 or 22% of net sales for the same period in 2002. These increases were primarily due to the Company returning to the Consumer Electronics Show in Las Vegas in January 2003 after a one year absence. For the third quarter ended March 31, 2003, income from operations was $1,579,307 versus $1,801,749 for the same period in the prior year. Income from operations for the nine months ended March 31, 2003 was $4,687,129 as compared to $4,989,589 for the same period in 2002. Effective July 1, 1998, the Company entered into a License Agreement and an Addendum thereto with Logitech Electronics Inc. of Ontario, Canada whereby the Company licensed to Logitech the right to sell multimedia/computer speakers under the Koss brand name. This License Agreement covers North America and certain countries in South America and Europe, requiring royalty payments by Logitech through June 30, 2008, subject to certain minimum annual royalty amounts. 9 of 18

The Company has a License Agreement with Jiangsu Electronics Industries Limited, a subsidiary of Orient Power Holdings Limited, by way of an assignment of a previously existing License Agreement with Trabelco N.V. Orient Power is based in Hong Kong and has an extensive portfolio of audio and video products. This License Agreement covers the United States, Canada, and Mexico, and has been renewed through December 31, 2003. Pursuant to this License Agreement, Jiangsu Electronics has agreed to meet certain minimum royalty amounts each year. The products covered by this License Agreement include various consumer electronics products. Royalty income for the quarter ended March 31, 2003 was $34,015, compared to $137,258 for the quarter ended March 31, 2002. For the nine month period ended March 31, 2003, royalty income was $452,736, compared to $570,805 for the period ending March 31, 2002. These decreases were due primarily to Jiangsu Electronics experiencing a huge decline in January sales. Interest income for the quarter ended March 31, 2003 was $1,851 as compared to $751 for the same quarter in 2002. For the nine month period ended March 31, 2003 interest income was $8,632, compared to $23,021 for the nine month period ended March 31, 2002. The decrease in interest income in 2003 is a result of lower levels of invested excess cash. There was no interest expense recorded for the quarter as compared to $31,549 for the same period in the prior year. On October 2, 2001, the Company declared a 2 for 1 stock split of the Company's common stock for stockholders of record on October 22, 2001, with the effective date being November 5, 2001. All earnings per common share amounts herein have been restated to give effect to the common stock split. On March 24, 2003, the Company declared a quarterly cash dividend of $0.13 per share payable on April 15, 2003 to stockholders of record on March 31, 2003, which is recorded as dividends payable. New Accounting Pronouncements In July 2001, the Financial Accounting Standards Board ("FASB") issued Statement of Financial Accounting Standards ("SFAS") No. 143, "Accounting for Asset Retirement Obligations" and in August 2001, issued SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets." SFAS No. 143 establishes accounting standards for the recognition and measurement of an asset retirement obligation. SFAS No. 144 addresses financial accounting and reporting for the impairment or disposal of long-lived assets, superseding SFAS No. 121. SFAS No. 143 and SFAS No. 144 were effective for the Company on July 1, 2002. The statements did not have an impact on the Company's results of operations or financial position. In June 2002, the FASB issued SFAS No. 146, "Accounting for Exit or Disposal Activities." This statement addresses the recognition, measurement, and reporting of costs associated with exit and disposal activities, including restructuring activities. The scope of the current statement also includes (1) costs related to a termination contract that is not a capital lease and (2) termination benefits that employees who are involuntarily terminated receive under the terms of a one-time benefit arrangement that is not an ongoing benefit arrangement or an individual deferred-compensation contract. SFAS No. 146 will be effective for exit or disposal activities that are initiated after December 31, 2002. The implementation of this issue did not have an impact on the Company's results of operations for the quarter ended March 31, 2003. In November 2002, the FASB issued FASB Interpretation No. 45, "Guarantor's Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees." This Interpretation elaborates on the disclosures to be made by a guarantor in its interim and annual financial statements about its 10 of 18

obligations under certain guarantees that it has issued. It also clarifies that a guarantor is required to recognize, at the inception of a guarantee. This Interpretation does not prescribe a specific approach for subsequently measuring the guarantor's recognized liability over the term of the related guarantee. This Interpretation also incorporates, without change, the guidance in FASB Interpretation No. 34, Disclosure of Indirect Guarantees of Indebtedness of Others, which is being superseded. The initial recognition and measurement provisions of this Interpretation are applicable on a prospective basis to guarantees issued or modified after December 31, 2002, irrespective of the guarantor's fiscal year-end. The disclosure requirements in this Interpretation are effective for financial statements of interim or annual periods ending after December 15, 2002. At March 31, 2003, the Company has issued no guarantees that qualify for disclosure in this interim financial statement. In December 2002, the FASB issued SFAS No. 148, "Accounting for Stock-Based Compensation -- Transition and Disclosure, an amendment of FASB Statement No. 123." This Statement amends SFAS No. 123, "Accounting for Stock-Based Compensation," to provide alternative methods of transition for a voluntary change to the fair value based method of accounting for stock-based employee compensation. In addition, this Statement amends the disclosure requirements of SFAS No. 123 to require prominent disclosures in both annual and interim financial statements about the method of accounting for stock-based employee compensation and the effect of the method used on reported results. SFAS No. 148 will be effective for the Company on July 1, 2003. The Company is currently evaluating the impact of this statement on its results of operations. ITEM 4. CONTROLS AND PROCEDURES. The Company's management, including the Chief Executive Officer/Chief Financial Officer, evaluated the Company's disclosure controls and procedures (as defined in Exchange Act Rules 13a-14(c) and 15d-14(c)) within 90 days of the filing of this report and concluded that the Company's disclosure controls and procedures were effective. There were no significant changes in the Company's internal controls or in other factors that could significantly affect these controls, including any corrective actions with regard to significant deficiencies and material weaknesses subsequent to the date of their evaluation. Management, including the Chief Executive Officer/Chief Financial Officer, periodically reviews the Company's internal controls for effectiveness and plans to conduct quarterly evaluations of its disclosure controls and procedures.
