SPARTON CORPORATION & SUBSIDIARIES
Notes to Condensed Consolidated Financial Statements (Unaudited)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - The following is a summary of the Company’s accounting policies not discussed elsewhere within this report.

Basis of presentation - The accompanying unaudited Condensed Consolidated Financial Statements of Sparton Corporation and subsidiaries have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions to Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements. All significant intercompany transactions and accounts have been eliminated. The Condensed Consolidated Balance Sheet at March 31, 2005, and the related Condensed Consolidated Statements of Operations and Cash Flows for the nine-month periods ended March 31, 2005 and 2004, are unaudited, but include all adjustments (consisting of normal recurring accruals), which the Company considers necessary for a fair presentation of such financial statements. Certain reclassifications of prior period amounts have been made to conform to the current presentation. Operating results for the nine-month period ended March 31, 2005, are not necessarily indicative of the results that may be expected for the fiscal year ended June 30, 2005.

The balance sheet at June 30, 2004, has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements. For further information, refer to the Consolidated Financial Statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended June 30, 2004.

Operations - The Company provides design and electronic manufacturing services, which include a complete range of engineering, pre-manufacturing and post-manufacturing services. Capabilities range from product design and development through after-market support. All facilities, with the exception of Vietnam which is currently under-going the evaluation process, are certified to ISO 9001, with many having additional certifications. The Company’s operations are in one line of business, electronic contract manufacturing services (EMS). Products and services include complete “Box Build” products for Original Equipment Manufacturers, microprocessor-based systems, transducers, printed circuit boards and assemblies, sensors and electromechanical devices. Markets served are in the medical/scientific instrumentation, aerospace, and industrial/other, with a focus on regulated markets. The Company also develops and manufactures sonobuoys, anti-submarine warfare (ASW) devices, used by the U.S. Navy and other free-world countries. Many of the physical and technical attributes in the production of sonobuoys are the same as those required in the production of the Company’s other electrical and electromechanical products and assemblies.

Use of estimates - Accounting principles generally accepted in the United States of America require management to make estimates and assumptions that affect the disclosure of assets and liabilities and the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Revenue recognition - The Company’s net sales are comprised primarily of product sales, with supplementary revenues earned from engineering and design services. Standard contract terms are FOB shipping point. Revenue from product sales is generally recognized upon shipment of the goods; service revenue is recognized as the service is performed or under the percentage of completion method, depending on the nature of the arrangement. Long-term contracts relate principally to government defense contracts. These contracts are accounted for based on completed units accepted and their estimated average contract cost per unit. Development contracts are accounted for based on percentage of completion. Costs and fees billed under cost-reimbursement-type contracts are recorded as sales. A provision for the entire amount of a loss on a contract is charged to operations as soon as the loss is determinable. Shipping and handling costs are included in costs of goods sold.

Market risk exposure - The Company manufactures its products in the United States and Canada, and most recently in Vietnam. Sales of the Company’s products are in the U.S. and Canada, as well as other foreign markets. The Company is potentially subject to foreign currency exchange rate risk relating to intercompany activity and balances, receipts from customers, and payments to suppliers in foreign currencies. Also, adjustments related to the translation of the Company’s Canadian financial statements into U.S. dollars are included in current earnings. The Company’s Vietnamese translation gains and losses are carried in accumulated other comprehensive income (loss) within the shareowners’ equity section of the Company’s balance sheet. As a result, the Company’s financial results could be affected by factors such as changes in foreign currency exchange rates or weak economic conditions in the domestic and foreign markets in which the Company operates. However, minimal third party receivables and payables are denominated in foreign currency and the related market risk exposure is considered to be immaterial. Historically, foreign currency gains and losses related to intercompany activity and balances have not been significant. However, recently due to the strengthening Canadian dollar the impact of transaction and translation gains has increased. While a reversal of these recent gains is not anticipated, if the exchange rate were to decline the Company’s financial position could be significantly affected.

6

The Company has financial instruments that are subject to interest rate risk, principally short-term investments. Historically, the Company has not experienced material gains or losses due to such interest rate changes. Based on the current holdings of short-term investments, the interest rate risk is not considered to be material.

New accounting standards - In December 2004, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards (SFAS) No. 123(R), “Share-Based Payment”, which replaces SFAS No. 123, “Accounting for Stock-Based Compensation”, and supersedes APB Opinion No. 25, “Accounting for Stock Issued to Employees”. The Statement requires that the cost resulting from all share-based payment transactions be recognized in the financial statements. The Statement also establishes fair value as the measurement objective in accounting for share-based payment arrangements and requires all entities to apply a fair-value-based measurement method in accounting for share-based payment transactions with employees, except for equity instruments held by employee share ownership plans. The Statement is effective for the Company beginning July 1, 2005, and is required to be adopted using a “modified prospective” method. Under the modified prospective method, the Statement applies to new awards and to awards modified, repurchased or cancelled after the effective date. Additionally, compensation cost for the unvested portion of awards as of the effective date is required to be recognized as the awards vest after the effective date. The Company does not expect the requirements of this Statement will have a significant impact on its results of operations or financial position.

In November 2004, the FASB issued SFAS No. 151, “Inventory Costs” (SFAS No. 151), which amends the guidance in Accounting Research Bulletin No. 43, Chapter 4, “Inventory Pricing”. The Statement requires that the accounting for abnormal amounts of idle facility expense, freight handling costs, and wasted material (spoilage) be recognized as current-period charges. In addition, the Statement requires that the allocation of fixed production overhead to the costs of conversion be based on the normal capacity of the production facilities. The Statement is effective for the Company for inventory costs incurred beginning July 1, 2005. The Company does not expect the requirements of this Statement will have any impact on its results of operations or financial position.

In December 2004, the FASB issued SFAS No. 153, “Exchange of Nonmonetary Assets, an amendment of APB Opinion No. 29” (SFAS No. 153), which addresses the measurement of exchanges of nonmonetary assets. The Statement eliminates the exception for nonmonetary exchanges of similar productive assets and replaces it with a general exception for exchange of nonmonetary assets that do not have commercial substance. It also specifies that a nonmonetary exchange has commercial substance if the future cash flows of the entity are expected to change significantly as a result of the exchange. The Statement is effective for the Company beginning July 1, 2005. The Company does not expect the requirements of the Statement will have a significant impact on its results of operations or financial position.

During fiscal 2004, the Company purchased a manufacturing facility in Albuquerque, New Mexico, that replaced an existing plant in Rio Rancho, New Mexico, which was subsequently sold. Because these transactions were reported separately, at fair market value, there would have been no change to how these transactions were recorded for financial reporting purposes had SFAS No. 153 been in effect during fiscal 2004. The tax treatment for the sale and purchase of these facilities was as a like-kind exchange.

Recently there have been official discussions and clarifications of certain provisions of FASB Statement No. 13, “Accounting for Leases”. The Company does not have any capital leases. All leases are operating leases, mainly for the lease of machinery and equipment, with monthly payments over a fixed term in equal, non-escalating amounts. The Company does not expect these clarifications to have any impact on its results of operations or financial position.

Periodic benefit cost - The Company follows the disclosure requirements of SFAS No. 132(R). For the three months and nine months ended March 31, 2005 and 2004, $96,000 and $481,000 and $360,000 and $545,000 of expense has been recorded, respectively. Total net periodic benefit cost for fiscal 2005 will be $480,000, compared to total net periodic benefit cost reported for fiscal 2004 of $727,000. For the three months and nine months ended March 31, 2005 and 2004, respectively, net periodic benefit cost includes the effect of changes resulting from the actuarial valuations performed as of the periods’ closing. Fiscal 2005 and 2004 anticipated and actual annual reported expense amount to $480,000 and $727,000, respectively. The decrease from prior year is primarily due to improved interest rates, and return on and valuation of plan assets. The components of net periodic pension expense for each of the periods presented were as follows:

7

Stock options - Pending the effective date of SFAS No. 123(R), the Company continues to follow APB No. 25 and related Interpretations in accounting for its employee stock options. Under APB No. 25, no compensation expense is recognized, as the exercise price of the Company’s employee stock options equals the market price of the underlying stock on the date of grant. The Company follows the disclosure requirements of SFAS No. 123 as amended by SFAS No. 148.

The Company has an incentive stock option plan under which 760,000 common shares were reserved for option grants to key employees and directors at the fair market value of the stock at the date of the grant. As of March 31, 2005, there were 533,442 shares outstanding under option, with prices ranging from $3.24 to $8.90, a weighted average remaining contractual life of 2.2 years, and a weighted average exercise price of $5.89. The following table summarizes information about stock options outstanding and exercisable at March 31, 2005:

Under the plan at March 31, 2005, exercisable options and the per share weighted average exercise price were 380,177 and $5.54, respectively, with 159,561 remaining shares available for grant.

The following sets forth a reconciliation of net income (loss) and earnings (loss) per share information for the three months and nine months ended March 31, 2005 and 2004, as if the Company had recognized compensation expense based on the fair value at the grant date for awards under the plan. For purposes of computing pro forma net income (loss), the fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model.

2. INVENTORIES - Inventories are valued at the lower of cost (first-in, first-out basis) or market and include costs related to long-term contracts. Inventories, other than contract costs, are principally raw materials and supplies. The following are the major classifications of inventory:

Work in process and finished goods inventories include $1.1 and $4.3 million of completed, but not yet accepted sonobuoys at March 31, 2005 and June 30, 2004, respectively. Inventories are reduced by progress billings to the U.S. government of approximately $6,915,000 and $2,125,000 at March 31, 2005 and June 30, 2004, respectively.

3. EARNINGS (LOSS) PER SHARE - On November 9, 2004, Sparton’s Board of Directors approved a 5% stock dividend. Eligible shareowners of record on November 23, 2004, received the stock dividend on December 15, 2004. To record the stock dividend, an amount equal to the fair market value of the common stock issued was transferred from retained earnings ($3,723,000) to common stock ($522,000) and capital in excess of par value ($3,198,000), with the balance ($3,000) paid in cash in lieu of fractional shares of stock. Accordingly, all share and per share information for fiscal 2005 and 2004 has been adjusted to reflect the impact of all stock dividends declared for the periods shown.

8

Due to the Company’s reported net loss for the nine months ended March 31, 2004, 146,163 outstanding stock option share equivalents were excluded from the computation of diluted earnings per share because their inclusion would have been anti-dilutive. Basic and diluted earnings per share were computed based on the following:

4. COMPREHENSIVE INCOME (LOSS) - Comprehensive income (loss) includes net income (loss) as well as unrealized gains and losses, net of tax, on investment securities owned and investment securities held by an investee accounted for by the equity method, which are excluded from net income. In addition, translation gains and losses on the Company’s Vietnam subsidiary are included in comprehensive income (loss). Unrealized gains and losses, net of tax, are reflected as a direct charge or credit to shareowners’ equity. Total comprehensive income (loss) is as follows for the three months and nine months ended March 31, 2005 and 2004, respectively:

At March 31, 2005 and June 30, 2004, shareowners’ equity includes accumulated other comprehensive income (loss) of $(66,000) and $62,000, respectively, net of tax. The components of these amounts are as follows:

5. INVESTMENT SECURITIES - The fair value of cash and cash equivalents, accounts receivable, and accounts payable approximate their carrying value. Cash and cash equivalents consist of demand deposits and other highly liquid investments with an original term of three months or less. The investment portfolio has various maturity dates up to 28 years. A daily market exists for all investment securities. The Company believes that the impact of fluctuations in interest rates on its investment portfolio should not have a material impact on financial position or results of operations. Investments in debt securities that are not cash equivalents and marketable equity securities have been designated as available-for-sale. Those securities are reported at fair value, with net unrealized gains and losses included in accumulated other comprehensive income, net of applicable taxes. Unrealized losses that are other than temporary are recognized in earnings. The Company does not believe there are any significant individual unrealized losses as of March 31, 2005, which would represent other than temporary losses, and there are no unrealized losses with a duration of one year or more. Realized gains and losses on investments are determined using the specific identification method. It is the Company’s intention to use these investment securities to provide working capital, fund the expansion of its business and for other business purposes.

At March 31, 2005, the Company had net unrealized losses of $247,000. At that date, the net after-tax effect of these losses was $156,000, which is included in accumulated other comprehensive income within shareowners’ equity. For the nine months ended March 31, 2005 and 2004, purchases of investment securities totaled $8,870,000 and $1,509,000, and sales of investment securities totaled $6,501,000 and $7,353,000, respectively.

The Company owns a 14% interest in Cybernet Systems Corporation (Cybernet), 12% on a fully diluted basis. This investment, with a carrying value of $1,727,000 and $1,677,000 at March 31, 2005 and June 30, 2004, respectively, represents the Company’s

9

equity interest in Cybernet’s net assets plus $770,000 of goodwill (no longer being amortized in accordance with SFAS No. 142, “Goodwill and Other Intangible Assets”). The investment in Cybernet is accounted for under the equity method, and is included in other assets on the condensed consolidated balance sheet. The Company believes that the equity method is appropriate given Sparton’s level of involvement in Cybernet. Prior to June 2002, Sparton accounted for its Cybernet investment using the cost method, which reflected a more passive involvement with Cybernet’s operations. Sparton’s current President and CEO is one of three Cybernet Board members, and as part of that position is actively involved in Cybernet’s oversight and operations. In addition, he has a strategic management relationship with the owners, who are also the other two board members, resulting in his additional involvement in pursuing areas of common interest for both Cybernet and Sparton. The Company’s share of unrealized gains (losses) on available-for-sale securities held by Cybernet is carried in accumulated other comprehensive income (loss) within the shareowners’ equity section of the Company’s balance sheet.

The contractual maturities of debt securities, and total equity securities as of March 31, 2005, were as follows:

6. COMMITMENTS AND CONTINGENCIES - One of Sparton’s former manufacturing facilities, located in Albuquerque, New Mexico (Coors Road), has been involved with ongoing environmental remediation since the early 1980’s. At March 31, 2005, Sparton has accrued $6,962,000 as its estimate of the minimum future undiscounted financial liability, of which $627,000 is classified as a current liability and included in accrued liabilities. Amounts charged to operations, principally legal and consulting fees, for the nine months ended March 31, 2005 and 2004 were $282,000 and $240,000, respectively. These costs were generally incurred in pursuit of various claims for reimbursement/recovery. The Company’s minimum cost estimate is based upon existing technology and excludes legal and related consulting costs, which are expensed as incurred. The Company’s estimate includes equipment, operating, and continued monitoring costs for onsite and offsite pump and treat containment systems.

In fiscal 2003, Sparton reached an agreement with the United States Department of Energy (DOE) and others to recover certain remediation costs. Under the settlement terms, Sparton received cash and the DOE agreed to reimburse Sparton for 37.5% of certain future environmental expenses in excess of $8,400,000 incurred from the date of settlement. Uncertainties associated with environmental remediation contingencies are pervasive and often result in wide ranges of reasonably possible outcomes. Estimates developed in the early stages of remediation can vary significantly. Normally a finite estimate of cost does not become fixed and determinable at a specific point in time. Rather, the costs associated with environmental remediation become estimable over a continuum of events and activities that help to frame and define a liability. Factors which cause uncertainties for the Company include, but are not limited to, the effectiveness of the current work plans in achieving targeted results and proposals of regulatory agencies for desired methods and outcomes. It is possible that cash flows and results of operations could be significantly affected by the impact of changes associated with the ultimate resolution of this contingency.

Some of the printed circuit boards supplied to the Company for its Aerospace sales have been discovered to have intermittent defects. The defect occurred during production at the board manufacturer’s facility, prior to shipment to Sparton for further processing. All of the lots involved have yet to be identified and Sparton, the board manufacturer, and the end customer who received the defective boards are working to contain the defective boards. As of this date no claims have been made or litigation commenced regarding this matter. The extent of Sparton’s exposure, if any, is unknown at this time, thus nothing has been accrued related to this contingency at March 31, 2005.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following is management’s discussion and analysis of certain significant events affecting the Company’s earnings and financial condition during the periods included in the accompanying financial statements. Additional information regarding the Company can be accessed via Sparton’s website at www.sparton.com. Information provided at the website includes, among other items, the Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, Quarterly Earnings Releases, News Releases, and the Code of Business Conduct and Ethics, as well as the various committee charters of the Board of Directors. These items are also available, free of charge, by contacting the Company’s Shareowners’ Relations department. The Company’s operations are in one line of business, electronic contract manufacturing services (EMS). Sparton’s capabilities range from product design and development through aftermarket support, specializing in total business solutions for government, medical/scientific instrumentation, aerospace and industrial/other markets. These include the design, development and/or manufacture of electronic parts and assemblies for both government and commercial customers worldwide. Governmental sales are mainly sonobuoys.

The Private Securities Litigation Reform Act of 1995 reflects Congress’ determination that the disclosures of forward-looking information is desirable for investors and encourages such disclosure by providing a safe harbor for forward-looking statements by corporate management. This report on Form 10-Q contains forward-looking statements within the scope of the Securities Act of 1933 and the Securities Exchange Act of 1934. The words “expects,” “anticipates,” “believes,” “intends,” “plans,” and similar expressions, and the negatives of such expressions, are intended to identify forward-looking statements. In addition, any statements which refer to expectations, projections or other characterizations of future events or circumstances are forward-looking statements. The Company undertakes no obligation to publicly disclose any revisions to these forward-looking statements to reflect events or circumstances occurring subsequent to filing this Form 10-Q with the Securities and Exchange Commission (SEC). These forward-looking statements are subject to risks and uncertainties, including, without limitation, those discussed below. Accordingly, Sparton’s future results may differ materially from historical results or from those discussed or implied by these forward-looking statements. The Company notes that a variety of factors could cause the actual results and experience to differ materially from anticipated results or other expectations expressed in the Company’s forward-looking statements.

Sparton, as a high-mix, low to medium-volume supplier, provides rapid product turnaround for customers. High-mix pertains to customers needing multiple product types with generally lower volume manufacturing runs. As a contract manufacturer with customers in a variety of markets, the Company has substantially less visibility to end user demand and, therefore, forecasting sales can be problematic. Customers may cancel their orders, change production quantities and/or reschedule production for a number of reasons. Depressed economic conditions may result in customers delaying delivery of product, or the placement of purchase orders for lower volumes than previously anticipated. Unplanned cancellations, reductions, or delays by customers negatively impact the Company’s results of operations. As many of the Company’s costs and operating expenses are relatively fixed within given ranges of production, a reduction in customer demand can disproportionately affect the Company’s gross margins and operating income. The majority of the Company’s sales have historically come from a limited number of customers. Significant reductions in sales to, or a loss of, one of these customers could materially impact business if the Company were not able to replace those lost sales with new business.

Other risks and uncertainties that may affect operations, performance, growth forecasts and business results include, but are not limited to, timing and fluctuations in U.S. and/or world economies, competition in the overall EMS business, availability of production labor and management services under terms acceptable to the Company, Congressional budget outlays for sonobuoy development and production, Congressional legislation, foreign currency exchange rate risk, uncertainties associated with the costs and benefits of new facilities, including the new plant in Vietnam, and the closing of others, uncertainties associated with the outcome of litigation, changes in the interpretation of environmental laws and the uncertainties of environmental remediation. A further risk factor is the availability and cost of materials. The Company has encountered availability and extended lead time issues on some electronic components in the past when market demand has been strong, this resulted in higher prices and late deliveries. Additionally, the timing of sonobuoy sales to the U.S. Navy is dependent upon access to the test range and successful passage of product tests performed by the U.S. Navy. Reduced governmental budgets have made access to the test range less predictable and less frequent than in the past. Finally, the Sarbanes-Oxley Act of 2002 has required changes in, and formalization of, some of the Company’s corporate governance and compliance practices. The SEC and New York Stock Exchange have also passed new rules and regulations requiring additional compliance activities. Compliance with these rules has increased administrative costs, and it is expected that certain of these costs will continue indefinitely. Management cautions readers not to place undue reliance on forward-looking statements, which are subject to influence by the enumerated risk factors as well as unanticipated future events.

The following discussion should be read in conjunction with the Condensed Consolidated Financial Statements and Notes thereto.

RESULTS OF OPERATIONS

Sales for the three-month period ended March 31, 2005, totaled $41,561,000, a decrease of $2,005,000 (4.6%) from the same quarter last year. Government sales were lower than expected due to the rescheduling of engineering redesign work, sonobuoy drop test failures, and manufacturing transitioning between sonobuoy contracts. Government sales are anticipated to improve through the remainder of the fiscal year as some of these issues are now resolved. Industrial sales improved mainly due to increased sales to existing customers. It is uncertain if this increased demand will continue for the balance of this fiscal year. Aerospace sales were also above the prior year sales due to increased sales to an existing customer in the commercial aerospace market. A large component of this increased demand was due to higher sales of products related to aircraft collision avoidance systems mandated for installation in all commercial aircraft. This increased demand is not anticipated to continue. Medical/Scientific Instrumentation was down from the prior year due to overall lower demand from existing customers in this market and new program delays. While the Company has added several new customers, and/or products in the medical device area, the volume of new business has not been as high as previously anticipated.

The following table presents income statement data as a percentage of net sales for the three-month periods ended March 31, 2005 and 2004:

An operating loss of $2,000 was reported for the three months ended March 31, 2005, compared to operating income of $133,000 for the three months ended March 31, 2004. Gross profit percentage for the three months ended March 31, 2005, was 8.0%, down from 8.2% for the same period last year. The depressed margin is reflective of a less favorable product mix and increased costs related to several program start-ups. Selling and administrative expenses are consistent with the prior year.

Interest and investment income increased $74,000 to $231,000 in fiscal 2005. This increase was mainly due to increased funds available for investment and improved interest rates. Other expense-net in fiscal 2005 was $30,000, versus $65,000 in fiscal 2004. Translation adjustments, along with gains and losses from foreign currency transactions, are included in other income and, in the aggregate, amounted to a loss of $12,000 and $10,000 during the three months ended March 31, 2005 and 2004, respectively. During the third quarter, the Company’s annual effective tax rate was estimated to be 28%, rather than the previously anticipated 32%. The Company’s recorded adjustment to the currently estimated rate resulted in a credit to third quarter income tax expense of $168,000. This, combined with normal third quarter income tax expense of $54,000, resulted in a net income tax credit of $114,000 for the third quarter. Variables affecting the effective tax rate include, but are not limited to, extraterritorial tax credits, Canadian tax loss carryforwards, effect of translation income and loss, and utilization of contribution carryforwards. This estimated tax rate, while based on the Company’s knowledge and expectations at this point in time, may change based on actual fourth quarter activity and results of operations.

12

Due to the factors described above, the Company reported net income of $308,000 ($0.04 per share, basic, and $0.03 per share, diluted) for the three months ended March 31, 2005, versus $156,000 ($0.02 per share, basic and diluted) for the corresponding period last year.

Sales for the nine-month period ended March 31, 2005, totaled $121,276,000, an increase of $8,045,000 (7.1%) from the same period last year. Government sales decreased, and included $4.7 million of a delayed sonobuoy sale originally anticipated to ship in fiscal 2004. Government sales were lower than anticipated due to production interruptions at the Company’s Florida facilities, as several tropical storms disrupted operations in the first quarter of fiscal 2005. In addition, rescheduling of engineering redesign work, failed sonobuoy drop tests, and lack of access to the U.S. Navy’s test site further depressed sales. Government sales are anticipated to improve in the final quarter of this fiscal year. Industrial market sales increased from the same period last year. This increase was attributed to increased demand from two existing customers, it is uncertain if this demand will continue for the balance of this fiscal year. Sales to the aerospace markets continue to grow, increasing 29.6% over the prior year. In general, this reflects stronger demand in the commercial aerospace market, primarily increased demand for products related to aircraft collision avoidance systems mandated for installation in all commercial aircraft. Approximately $6.9 million of the aerospace increase was attributable to increased orders from one customer, to which the Company supplies product to six manufacturing facilities. The increased demand for the collision avoidance products is not anticipated to continue throughout the final quarter. Medical/Scientific Instrumentation sales declined from the prior year. This decrease resulted from overall lower demand from existing customers in this market area and new program delays. While the Company has added several new customers, and/or products in the medical device area, the volume of new business has not been as high as previously anticipated.

The majority of the Company’s sales come from a small number of customers. Sales to our six largest customers, including government sales, accounted for approximately 76% and 72% of net sales in fiscal 2005 and 2004, respectively. Five of the customers, including government, were the same both years. One of these customers, with six separate facilities as discussed above, provided 28% and 24% of the sales through March 31, 2005 and 2004, respectively.

The following table presents income statement data as a percentage of net sales for the nine months ended March 31, 2005 and 2004:

Operating income of $3,119,000 was reported for the nine months ended March 31, 2005, compared to a loss of $5,359,000 for the nine months ended March 31, 2004. Gross profit percentage for the nine months ended March 31, 2005, was 10.9%, up from 4.8% for the same period last year. While the tropical storms largely bypassed the Company’s two Florida facilities, extensive preparations were undertaken for the storms. This unexpected activity, along with the minor damage that was experienced and unproductive wages, resulted in costs of approximately $500,000 being charged in the first quarter of fiscal 2005. Also included

13

in the current year’s gross profit was a settlement in the second quarter of fiscal 2005 with a customer, which resulted in the Company’s recovery of $500,000 of prior period start-up expenses. The prior year’s depressed margin reflects the inclusion of costs on the start-up phase of several major programs, as well as final charges incurred at the completion of one sonobuoy contract that had experienced technical problems. In addition, the prior year’s margin included a redesign effort on an existing product line, which resulted in a charge to operations of $519,000. The lowered selling and administrative expenses are primarily the result of decreased bid and proposal and research and development expenses for fiscal 2005, which were approximately $1.7 million below the same nine month period last year. These cost reductions are not indicative of reduced bid and proposal activity, which is currently at an all time high, but primarily the result of a one time sonobuoy engineering project which has been completed.

Interest and investment income increased $143,000 to $653,000 in fiscal 2005. This increase was due to increased funds available for investment and improving investment rates. Other income-net in fiscal 2005 was $647,000, versus an expense of $374,000 in fiscal 2004. Translation adjustments, along with gains and losses from foreign currency transactions, are included in other income and, in the aggregate, amounted to a gain of $644,000 and $163,000 during the nine months ended March 31, 2005 and 2004, respectively. Other expense-net in the prior year included a charge of $538,000 for workers’ compensation insurance adjustments related to the Company’s previously owned automotive segment.

Due to the factors described above, the Company reported net income of $3,175,000 ($0.36 per share, basic and diluted) for the nine months ended March 31, 2005, versus a loss of $3,541,000 ($(0.40) per share, basic and diluted) for the corresponding period last year.

LIQUIDITY AND CAPITAL RESOURCES

For the nine-month period ended March 31, 2005, cash and cash equivalents decreased $133,000 to $10,687,000. Operating activities provided $7,288,000 in net cash flows. The primary source of cash was from operations, compared to a loss in fiscal 2004 resulting in a use of cash, as well as the adjustment for depreciation. The primary source of cash in fiscal 2004 was a decrease in accounts receivable. The decrease in accounts receivable in both fiscal 2005 and 2004 was reflective of the receipt of payments for the large volume of sales recognized in June 2004 and 2003. The change in cash flow related to inventory and prepaid expenses from the prior year is reflective of a large increase at June 30, 2004, of inventory due to delayed customer delivery schedules, as well as increased inventory for new customer contracts. Inventory levels at March 31, 2005, reflect a decrease in inventory, as these customers’ schedules were no longer delayed, as well as the start of several new customer contracts.

Cash flows used by investing activities for the nine-month period ended March 31, 2005, totaled $7,672,000, primarily for purchases of property, plant and equipment, which is discussed below. The purchase of, and proceeds from the sale of, investment securities are generally reflective of activity within the various investment options. In fiscal 2004 proceeds from the sale of investments were also used to fund purchases of property, plant and equipment.

Historically, the Company’s market risk exposure to foreign currency exchange and interest rates on third party receivables and payables has not been considered to be material, principally due to their short term nature and minimal receivables and payables designated in foreign currency. However, due to the recently strengthening Canadian dollar the impact of transaction and translation gains on intercompany activity and balances has increased. While a reversal of these recent gains is not anticipated, if the exchange rate were to materially decline the Company’s financial position could be significantly affected. The Company has had no short-term bank debt since December 1996, and currently has an unused informal line of credit totaling $20 million.

At March 31, 2005 and June 30, 2004, the aggregate government EMS backlog was approximately $52 million and $41 million, respectively. Current backlog includes the recent U.S. Navy sonobuoy contract awards, which totaled $21.7 million. A majority of the March 31, 2005, backlog is expected to be realized in the next 12-15 months. Commercial EMS orders are not included in the backlog. The Company does not believe the amount of commercial activity covered by firm purchase orders is a meaningful measure of future sales, as such orders may be rescheduled or cancelled without significant penalty.

Construction of the Company’s new plant in Vietnam is substantially complete. Preliminary prototype product is currently being produced, with regular production beginning in May. This new facility is anticipated to provide increased growth opportunities for the Company, in current as well as new markets. As the Company has not previously done business in this emerging market, there are many uncertainties and risks inherent in this venture. It is estimated that the total Company investment will approximate $5-$7 million, which includes land, building, and initial operating expenses. To date, approximately $2.0 million has been expended for the construction of the new facility, primarily in fiscal 2005. The new company operates under the name Spartronics. The Company is also continuing a program of identifying and evaluating potential acquisition candidates in both the defense and medical markets.

The Company has purchased a manufacturing facility in Albuquerque, New Mexico. This facility replaced an existing plant in Rio Rancho, New Mexico. The facility was purchased in December 2003 for approximately $4.5 million. The cost of additional remodeling and facility upgrades totaled approximately $2.0 million and were incurred, primarily in 2005, as the Company transitioned between facilities. The Rio Rancho plant was sold in June 2004 for approximately $1.7 million ($1.6 million after expenses related to the sale), resulting in a $844,000 gain. The Company leased the Rio Rancho facility until the transition to the new facility was completed in December 2004. The new facility is expected to provide economic benefits to the Company, accommodating customer products with higher technical requirements, as well as providing additional and more efficient manufacturing space in the Southwest.

No cash dividends were declared in either period presented. In November 2004, the Company approved a 5% stock dividend. This dividend was distributed December 15, 2004, to shareowners of record on November 23, 2004. At March 31, 2005, the Company had $92,164,000 in shareowners’ equity ($10.45 per share), $71,745,000 in working capital, and a 4.67:1.00 working capital ratio. For the foreseeable future (12-18 months), the Company believes it has sufficient liquidity for its anticipated needs, unless a significant business acquisition is identified and completed for cash.

CONTRACTUAL OBLIGATIONS AND COMMITMENTS

Information regarding the Company’s environmental liability payments, operating lease payments, and other commitments is provided in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operation,” of the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2004. There have been no material changes in contractual obligations since June 30, 2004.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Management’s discussion and analysis of financial condition and results of operations is based upon the Company’s consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. Significant accounting policies are summarized in Note 1 to the Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended June 30, 2004. The preparation of these financial statements requires management to make estimates and assumptions that affect the amounts reported for assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. Estimates are regularly evaluated and are based on historical experience and on various other assumptions believed to be reasonable under the circumstances. Actual results could differ from these estimates. The Company believes that of its significant accounting policies, the following involve a higher degree of judgment and complexity.

Environmental Contingencies

One of Sparton’s former manufacturing facilities, located in Albuquerque, New Mexico (Coors Road), has been the subject of ongoing investigations and remediation efforts conducted with the Environmental Protection Agency (EPA) under the Resource Conservation and Recovery Act (RCRA). Sparton has accrued its estimate of the minimum future non-discounted financial liability. The estimate was developed using existing technology and excludes legal and related consulting costs. The minimum cost estimate includes equipment, operating and monitoring costs for both onsite and offsite remediation. Sparton recognizes legal and consulting services in the periods incurred and reviews its EPA accrual activity quarterly. Uncertainties associated with environmental remediation contingencies are pervasive and often result in wide ranges of reasonably possible outcomes. It is possible that cash flows and results of operations could be materially affected by the impact of changes in these estimates.

Government Contract Cost Estimates

Government production contracts are accounted for based on completed units accepted with respect to revenue recognition and their estimated average cost per unit regarding costs. Losses for the entire amount of a contract are recognized in the period when such losses are determinable. Significant judgment is exercised in determining estimated total contract costs including, but not limited to, cost experience to date, estimated length of time to contract completion, costs for materials, production labor and support services to be expended, and known issues on remaining units to be completed. Estimated costs developed in the early stages of contracts can change significantly as the contracts progress, and events and activities take place. Significant changes in estimates can also occur when new designs are initially placed into production. The Company formally reviews its costs incurred-to-date and estimated costs to complete on all significant contracts on a quarterly basis and revised estimated total contract costs are reflected in the financial statements. Depending upon the circumstances, it is possible that the Company’s financial position, results of operations, and cash flows could be materially affected by changes in estimated costs to complete on one or more significant contracts.

15

Commercial Inventory Valuation Allowances

Inventory valuation allowances for commercial customer inventories require a significant degree of judgment and are influenced by the Company’s experience to date with both customers and other markets, prevailing market conditions for raw materials, contractual terms and customers’ ability to satisfy these obligations, environmental or technological materials obsolescence, changes in demand for customer products, and other factors resulting in acquiring materials in excess of customer product demand. Contracts with some commercial customers may be based upon estimated quantities of product manufactured for shipment over estimated time periods. Raw material inventories are purchased to fulfill these customer requirements. Within these arrangements, customer demand for products frequently changes, sometimes creating excess and obsolete inventories.

The Company regularly reviews raw material inventories by customer for both excess and obsolete quantities, with adjustments made accordingly. Wherever possible, the Company attempts to recover its full cost of excess and obsolete inventories from customers or, in some cases, through other markets. When it is determined that the Company’s carrying cost of such excess and obsolete inventories cannot be recovered in full, a charge is taken against income and a valuation allowance is established for the difference between the carrying cost and the estimated realizable amount. Conversely, should the disposition of adjusted excess and obsolete inventories result in recoveries in excess of these reduced carrying values, the remaining portion of the valuation allowances are reversed and taken into income when such determinations are made. It is possible that the Company’s financial position, results of operations and cash flows, could be materially affected by changes to inventory valuation allowances for commercial customer excess and obsolete inventories.

Allowance for Possible Losses on Receivables

The accounts receivable balance is recorded net of allowances for amounts not expected to be collected from customers. The allowance is estimated based on historical experience of write-offs, the level of past due amounts, information known about specific customers with respect to their ability to make payments, and future expectations of conditions that might impact the collectibility of accounts. Accounts receivable are generally due under normal trade terms for the industry. Credit is granted, and credit evaluations are periodically performed, based on a customers’ financial condition and other factors. Although the Company does not generally require collateral, cash in advance or letters of credit may be required from customers in certain circumstances, including some foreign customers. When management determines that it is probable that an account will not be collected, it is charged against the allowance for possible losses. The Company reviews the adequacy of its allowance monthly. The allowance for doubtful accounts was $16,000 and $46,000 at March 31, 2005 and June 30, 2004, respectively. If the financial condition of customers were to deteriorate, resulting in an impairment of their ability to make payment, an additional allowance may be required. Given the Company’s significant balance of government receivables and letters of credit from foreign customers, collection risk is considered minimal. Historically, uncollectible accounts have been generally insignificant and the minimal allowance is deemed adequate.

Pension Obligations

The Company calculates the cost of providing pension benefits under the provisions of SFAS No. 87. The key assumptions required within the provisions of SFAS No. 87 are used in making these calculations. The most significant of these assumptions are the discount rate used to value the future obligations and the expected return on pension plan assets. The discount rate is consistent with market interest rates on high-quality, fixed income investments. The expected return on assets is based on long-term returns and assets held by the plan, which is influenced by historical averages. If actual interest rates and returns on plan assets materially differ from the assumptions, future adjustments to the financial statements would be required. While changes in these assumptions can have a significant effect on the pension benefit obligations reported in the Condensed Consolidated Balance Sheets and the unrecognized gain or loss accounts, the effect of changes in these assumptions is not expected to have the same relative effect on net periodic pension expense in the near term. While these assumptions may change in the future based on changes in long-term interest rates and market conditions, there are no known expected changes in these assumptions as of March 31, 2005. As indicated above, to the extent the assumptions differ from actual results, there would be a future impact on the financial statements. The extent to which this will result in future expense is not determinable at this time as it will depend upon a number of variables, including trends in interest rates and the actual return on plan assets. For example, an increase in the return on the plan assets due to improved market conditions would reduce the unrecognized loss account and thus reduce future expense. While net periodic pension expense has increased during the past two years, no cash payments are expected to be required for the next several years due to the plan’s funded status.

OTHER

LITIGATION

One of Sparton’s former manufacturing facilities, located in Albuquerque, New Mexico, has been the subject of ongoing investigations conducted with the Environmental Protection Agency (EPA) under the Resource Conservation and Recovery Act (RCRA). The investigation began in the early 1980’s and involved a review of onsite and offsite environmental impacts.

At March 31, 2005, Sparton has accrued $6,962,000 as its estimate of the future undiscounted minimum financial liability related to this site. The Company’s cost estimate is based upon existing technology and excludes legal and related consulting costs, which are expensed as incurred. The Company’s estimate includes equipment and operating costs for onsite and offsite operations and is based on existing methodology. Uncertainties associated with environmental remediation contingencies are pervasive and often result in wide ranges of reasonably possible outcomes. Estimates developed in the early stages of remediation can vary significantly. Normally a finite estimate of cost does not become fixed and determinable at a specific point in time. Rather, the costs associated with environmental remediation become estimable over a continuum of events and activities that help to frame and define a liability. It is possible that cash flows and results of operations could be affected by the impact of the ultimate resolution of this contingency.

Some of the printed circuit boards supplied to the Company for its Aerospace sales have been discovered to have intermittent defects. The defect occurred during production at the board manufacturer’s facility, prior to shipment to Sparton for further processing. All of the lots involved have yet to be identified and Sparton, the board manufacturer, and the end customer who received the defective boards are working to contain the defective boards. As of this date no claims have been made or litigation commenced regarding this matter. The extent of Sparton’s exposure, if any, is unknown at this time, thus nothing has been accrued related to this contingency at March 31, 2005.

Sparton is currently involved with two legal actions, which are disclosed in Part II — “Other Information, Item 1. Legal Proceedings” of this report. At this time, the Company is unable to predict the outcome of either of these claims.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company manufactures its products in the United States and Canada, and most recently in Vietnam. Sales are to the U.S. and Canada, as well as other foreign markets. The Company is potentially subject to foreign currency exchange rate risk relating to intercompany activity and balances and to receipts from customers and payments to suppliers in foreign currencies. Also, adjustments related to the translation of the Company’s Canadian financial statements into U.S. dollars are included in current earnings. The Company’s Vietnamese translation gains and losses are carried in accumulated other comprehensive income (loss) within the shareowners’ equity section of the Company’s balance sheet. As a result, the Company’s financial results could be affected by factors such as changes in foreign currency exchange rates or weak economic conditions in the domestic and foreign markets in which the Company operates. However, minimal third party receivables and payables are denominated in foreign currency and the related market risk exposure is considered to be immaterial. Historically, foreign currency gains and losses related to intercompany activity and balances have not been significant. However, recently due to the strengthening Canadian dollar the impact of transaction and translation gains has increased. While a reversal of these recent gains is not anticipated, if the exchange rate were to materially decline the Company’s financial position could be significantly affected.

The Company has financial instruments that are subject to interest rate risk, principally short-term investments. Historically, the Company has not experienced material gains or losses due to such interest rate changes. Based on the current holdings of short-term investments, the interest rate risk is not considered to be material.

Item 4. CONTROLS AND PROCEDURES

The Company maintains internal control over financial reporting intended to provide reasonable assurance that all material transactions are executed in accordance with Company authorization, are properly recorded and reported in the financial statements, and that assets are adequately safeguarded. The Company also maintains a system of disclosure controls and procedures to ensure that information required to be disclosed in Company reports, filed or submitted under the Securities Exchange Act of 1934, is properly reported in the Company’s periodic and other reports.

17

As of March 31, 2005, an evaluation was updated by the Company’s management, including the CEO and CFO, on the effectiveness of the design and operation of the Company’s disclosure controls and procedures. Based on that evaluation, the Company’s management, including the CEO and CFO, concluded that the Company’s disclosure controls and procedures continue to be effective as of March 31, 2005. There have been no changes in the Company’s internal controls over financial reporting during the last fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II
OTHER INFORMATION

Item 1. Legal Proceedings

One of Sparton’s former manufacturing facilities, located in Albuquerque, New Mexico (Coors Road), has been involved with ongoing environmental remediation since the early 1980’s. At March 31, 2005, Sparton has accrued $6,962,000 as its estimate of the minimum future undiscounted financial liability, of which $627,000 is classified as a current liability and included in accrued liabilities. The Company’s minimum cost estimate is based upon existing technology and excludes legal and related consulting costs, which are expensed as incurred. The Company’s estimate includes equipment, operating, and continued monitoring costs for onsite and offsite pump and treat containment systems.

Factors, which cause uncertainties with respect to the Company’s estimate, include, but are not limited to, the effectiveness of the current work plans in achieving targeted results and proposals of regulatory agencies for desired methods and outcomes. It is possible that cash flows and results of operations could be significantly affected by the impact of changes associated with the ultimate resolution of this contingency. Uncertainties associated with environmental remediation contingencies are pervasive and often result in wide ranges of reasonably possible outcomes. Estimates developed in the early stages of remediation can vary significantly. Normally a finite estimate of cost does not become fixed and determinable at a specific point in time. Rather, the costs associated with environmental remediation become estimable over a continuum of events and activities that help to frame and define a liability. It is possible that cash flows and results of operations could be materially affected by the impact of the ultimate resolution of this contingency.

In fiscal 2003, Sparton reached an agreement with the United States Department of Energy (DOE) and others to recover certain remediation costs. Under the settlement terms, Sparton received cash and the DOE agreed to reimburse Sparton for 37.5% of certain future environmental expenses in excess of $8,400,000 incurred from the date of settlement.

In 1995, Sparton Corporation and Sparton Technology, Inc. (STI) filed a Complaint in the Circuit Court of Cook County, Illinois, against Lumbermens Mutual Casualty Company and American Manufacturers Mutual Insurance Company demanding reimbursement of expenses incurred in connection with its remediation efforts at the Coors Road facility based on various primary and excess comprehensive general liability policies in effect between 1959 and 1975. In 1999, the Complaint was amended to add various other excess insurers, including certain London market insurers and Fireman’s Fund Insurance Company. The case remains in pretrial activity.

In September 2002, STI filed an action in the U.S. District Court for the Eastern District of Michigan to recover certain unreimbursed costs incurred as a result of a manufacturing relationship with two entities, Util-Link, LLC (Util-Link) of Delaware and National Rural Telecommunications Cooperative (NRTC) of the District of Columbia. On or about October 21, 2002, the defendants filed a counterclaim seeking money damages, alleging that STI breached its duties in the manufacture of products for the defendants. The defendant NRTC asked for damages in the amount $20,000,000 for the loss of its investment in and loans to Util-Link. In addition, the defendant Util-Link had previously asked for damages in the amount of $25,000,000 for lost profits, which it no longer appears to be pursuing. Sparton has reviewed the respective claims and believes that the damages sought by NRTC were included in Util-Link’s claim for damages and, as such, were duplicative. Sparton believes the counterclaim to be without merit and intends to vigorously defend against it. These claims are now in the pretrial stage, with jury trial scheduled in Detroit, Michigan, in the September 2005 time-frame.

At this time, the Company is unable to predict the outcome of either of these two claims.
