INTRODUCTION

On May 31, 2006, Sparton Corporation, an Ohio Corporation (the “Company”) announced that it had entered into and closed on that date a membership purchase agreement (“Purchase Agreement”) to acquire Astro Instrumentation, LLC (“Astro”) located in Strongsville, Ohio. Astro is a contract manufacturer specializing in the design and production of medical devices for diagnostic and pharmaceutical customers. The Purchase Agreement provided for the sale and purchase of all of the outstanding membership interests of Astro.

The purchase price, approximately $26.15 million (excluding extinguishment or assumption of debt), was paid by a combination of cash in the amount of $18.65 million and notes totaling $7.5 million. Additional consideration may be paid to the sellers over the four years following the closing based on a percentage of earnings before interest and taxes. In addition, under the terms of the Purchase Agreement, the two individual sellers entered into non-competition agreements with the Company. The transaction was financed through a combination of cash and amounts borrowed under the Company’s loan facilities with National City Bank.

The newly acquired entity was renamed Astro Instrumentation, Inc. (“Astro, Inc.”), incorporated in the State of Michigan. The Company now operates the business as a wholly-owned subsidiary at its present location and with the current operating management and staff. The acquisition of Astro furthered the Company’s strategy of identifying and acquiring acquisition candidates for both the defense and medical device markets.

As permitted by Item 9.01(a)(4) of Form 8-K, audited historical financial statements of the acquired business, as well as unaudited combined proforma financial information, are being filed by this amendment to Form 8-K.

(“Exports”), a commonly controlled entity owned by the members of Astro. The assets and operations of Exports, a Domestic International Sales Corporation not acquired by Sparton Corporation, were insignificant to Astro’s historical operating results and financial position. The assets and operations of Exports are not included in Astro’s interim unaudited condensed financial statements for the three months ended March 31, 2006 or 2005.

		Independent Auditors’ Report

Cleveland Office 32125 Solon Road Suite 200 Cleveland, Ohio 44139 (440) 248-8787 fax (440) 248-0841 www.SSandG.com		To the Members Astro Instrumentation, LLC Strongsville, Ohio We have audited the accompanying combined balance sheet Astro Instrumentation, LLC as of December 31, 2005, and the related combined statements of income and owners’ equity and cash flows for the year then ended. These financial statements are the responsibility of Astro Instrumentation, LLC’s management. Our responsibility is to express an opinion on these financial statements based on our audit.

		We conducted our audit in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.

		In our opinion, the combined financial statements referred to above present fairly, in all material respects, the combined financial position of Astro Instrumentation, LLC as of December 31, 2005, and the combined results of operations and its cash flows for the year then ended in conformity with accounting principles generally accepted in the United States of America.

		The financial statements for the year ended December 31, 2004 were reviewed by us, and our report thereon, dated February 4, 2005, stated that we were not aware of any material modifications that should be made to those statements for them to be in conformity with generally accepted accounting principles. However, a review is substantially less in scope than an audit and does not provide a basis for the expression of an opinion on the financial statements taken as a whole.

NOTES TO COMBINED FINANCIAL STATEMENTS

DECEMBER 31, 2005 (AUDITED) AND 2004 (REVIEWED)

NOTE A — Significant accounting policies

Nature of operations

The accompanying combined financial statements include the accounts of Astro Instrumentation, LLC, and Astro Exports, Inc. both of which are under common control, collectively referred to as the Company. Astro Exports, Inc. began operations on February 18, 2004. All significant intercompany transactions have been eliminated in these combined financial statements.

The company is located in Strongsville, Ohio and is a contract manufacturer specializing in the design and manufacturing of medical devices for diagnostic and pharmaceutical companies.

Cash and cash equivalents

For purposes of the Statements of Cash Flows, the Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents.

Accounts receivable

The Company reports trade receivables at gross amounts due from customers. Because historical losses related to these receivables have been insignificant, management uses the direct write-off method to account for bad debts. On a continuing basis, management analyzes delinquent receivables and, if these receivables are determined to be uncollectible, they are written off through a charge against earnings.

Property and equipment

Furniture, equipment, computer equipment and related software are recorded at cost. Depreciation is computed by straight-line and accelerated methods over the estimated useful lives of the assets. Repairs and maintenance costs are expensed as incurred.

Concentrations of credit risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash. The Company places its cash with financial institutions and although at times during the year they had invested amounts in excess of federal insurance limits, management does not feel that the Company is exposed to any substantial credit risk. Also see Note G.

Income taxes

Astro Instrumentation, LLC, with the consent of its members, has elected under Chapter 1705 of the Ohio Revised Code to be formed as a limited liability company. Under this Chapter, Astro Instrumentation, LLC, is treated as a partnership for federal and state income tax purposes. In lieu of paying taxes at the company level, the members of a limited liability company are taxed on their proportionate share of the Company’s taxable income. Therefore, no provision or liability for federal or state income taxes has been included in the financial statements.

DECEMBER 31, 2005 (AUDITED) AND 2004 (REVIEWED)

NOTE A — Significant accounting policies

Income taxes (continued)

Astro Exports, Inc., with the consent of its shareholders, has elected to be taxed under the provisions of the Domestic International Sales Corporation of the Internal Revenue Code from its inception. Consequently, in lieu of corporate federal and state income taxes the shareholders of the Domestic International Sales Corporation are taxed on their proportionate share of the Company’s taxable income. Therefore, no provision or liability for federal or state income taxes has been included in the financial statements.

Loan fees

The loan fees are amortized on the straight-line method over five years., Amortization expense was $12,942 for each of the years ended December 31, 2005 and 2004.

Advertising costs

Advertising costs, which are included in operating expenses, are expensed as incurred. Advertising expenses were $14,957 and $29,751 for the years ended December 31, 2005 and 2004, respectively.

Deferred revenue

Deferred revenue represents deposits received from customers for services to be performed subsequent to year end.

Use of estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amount of assets and disclosures. Accordingly, actual results could differ from those estimates.

NOTE B — Inventories

All inventories are stated at the lower of cost (first-in, first-out method) or market. Inventories consisted of the following at December 31:


	2005		2004

Raw materials	$	7,164,479	$	5,862,441
Finished goods		815,651		292,896

NOTE D — Line of Credit

Interest is computed at LIBOR rate of 4.39% and 2.42% (at December 31, 2005 and December 31, 2004, respectively) plus 1.25%. The line of credit contains certain covenants with respect to Tangible Net Worth, Funded Debt to EBITDA and a Fixed Charge Coverage Ratio. These covenants have been met at December 31, 2005. This line of credit is secured by substantially all of the Company’s assets.

NOTE E — Bond payable

In 2002, the State of Ohio issued Ohio State Economic Development Revenue Bonds Series 2002-4 in the amount of $2,845,000. Subsequently, the Company entered into a loan agreement with the State of Ohio for $2,845,000 in order to finance the construction of a new manufacturing facility and corporate office. The interest rate varies based on the maturity date of the bonds. The maturity date and related interest are as follows:


			Semi-Annual
Maturity Date	Maturing Principal		Interest Rate

December 2006		105,000		3.00	%
December 2007		110,000		3.50	%
December 2008		110,000		3.50	%
December 2009		120,000		3.50	%
June 2010 — 2015		765,000		5.00	%
June 2016 — 2022		1,335,000		5.45	%

		2,545,000
Less original issue discount		28,271


Net balance	$	2,516,729

The interest rate on the bonds for 2005 was 2.75%. The bonds carry certain sinking fund requirements generally obligating the Company to deposit funds into a sinking fund. The sinking fund requires the Company to make monthly deposits of one twelfth of the annual obligation plus accrued interest.

The original issue discount is being amortized over the life of the bond. Amortization expense for each of the years ended December 31, 2005 and 2004 was $1,098, which is included in interest expense.

The bonds maturing after December 31, 2007 also include an obligation for deposits into the sinking fund. The obligation has been jointly and severally guaranteed by the members of the Company.

The Company also had an irrevocable letter of credit in the amount of $284,000 which is renewable annually.

UNAUDITED COMBINED PRO FORMA CONDENSED FINANCIAL INFORMATION

F-23

UNAUDITED COMBINED PRO FORMA CONDENSED FINANCIAL INFORMATION

Basis of Presentation

The unaudited combined pro forma condensed financial information set forth on the following pages gives effect to the acquisition of Astro Instrumentation, LLC (“Astro”), by Sparton Corporation (“Sparton”) as if the transaction had been completed on July 1, 2004 for purposes of the proforma statements of income, and as if it had been completed on March 31, 2006 for proforma balance sheet presentation purposes. The unaudited combined pro forma condensed financial statements are derived from the historical financial statements of Astro and Sparton.

Sparton will account for the acquisition under the purchase method of accounting. Accordingly, Sparton will establish a new basis for Astro’s assets and liabilities based upon the fair values thereof and the Sparton purchase price, including direct and incremental costs of the acquisition. The purchase accounting adjustments made in connection with the development of the unaudited combined pro forma condensed financial statements are preliminary and have been made solely for the purposes of developing such pro forma financial information and are based upon the assumptions described in the notes thereto. The pro forma adjustments do not reflect any operating efficiencies and cost savings that may be achieved with respect to the combined businesses, nor any adjustments to expenses for any future operating changes. Sparton may incur integration-related expenses not reflected in the pro forma financial statements, such as operational realignment. The following unaudited combined pro forma condensed financial information is not necessarily indicative of the financial position or operating results of the combined businesses that would have actually occurred had the acquisition been completed on the dates referred to above.

Sparton is unaware of events that would require a material change to the preliminary purchase price allocation. A final determination of potential additional purchase accounting adjustments, if any, as described in the following two sentences, will be made within periods prescribed in accordance with generally accepted accounting principles. The purchase agreement specifies that additional contingent cash purchase consideration may be paid by Sparton to the sellers of Astro over the four years following the closing based on a percentage of Astro’s earnings before interest, depreciation and taxes, and if ultimately earned and paid, will be added to goodwill. This additional contingent consideration, which will be measured annually with the start of the fiscal year beginning on July 1, 2006, will be based on Astro’s fiscal 2007-2010 operating performance.

This proforma information should be read in conjunction with the:

	•		Accompanying notes to the Unaudited Pro Forma Condensed Combined Balance Sheet and Statements of Income; and

	•		Separate historical consolidated financial statements and footnotes of Sparton Corporation and Subsidiaries for the fiscal year ended June 30, 2005 and the nine months ended March 31, 2006, which are incorporated herein by reference; and

	•		Separate historical financial statements and footnotes of Astro Instrumentation, LLC for its fiscal year ended December 31, 2005, and historical financial statements and footnotes of Astro Instrumentation, LLC for the three months ended March 31, 2006 and 2005, which are presented herein.

Sparton Corporation presents the unaudited pro forma condensed combined financial information for informational purposes only. The pro forma information is not necessarily indicative of what the financial position actually would have been had the Company completed the acquisition of Astro on March 31, 2006 nor is it necessarily indicative of what the Company’s operating results actually would have been had the Company completed the acquisition of Astro on July 1, 2004. In addition, the unaudited pro forma condensed combined financial information does not purport to be indicative of, or to project, the future financial position or operating results of the Company.

PRO FORMA ADJUSTMENTS TO COMBINED BALANCE SHEET

(a)

The following pro-forma adjustments affect cash and cash equivalents and short-term investments to reflect:

	•		Decrease to cash of $9,150,000 to reflect the cash portion ($8,650,000) of the Astro acquisition purchase price and estimated capitalized direct acquisition costs ($500,000).

	•		Decrease to cash of $4,208,220 to reflect the retirement at closing of Astro’s line-of-credit borrowings.

	•		Transfer to cash via liquidation of $5,000,000 in short-term investments to generate cash to partially fund the above transactions.

(b)		To adjust the basis of Astro assets acquired and liabilities assumed to their estimated fair values, to establish goodwill and identifiable intangible assets, and to capitalize certain direct and incremental acquisition costs, resulting from the Astro purchase price allocation.

(c)		To record the long-term debt that Sparton incurred to finance the acquisition.

PRO FORMA ADJUSTMENTS TO COMBINED STATEMENTS OF INCOME

(d)		To record incremental depreciation expense based on the fair value and remaining useful lives of Astro’s property, plant and equipment. Depreciation was calculated using accelerated and straight-line methods over lives generally ranging from one to twelve years on personal property and forty years on real property.

(e)		To record amortization expense on identifiable intangible assets. Non-compete agreements are amortized ratably over four (4) years. Customer relationships are amortized ratably over fifteen (15) years.

(f)		To reflect the lost opportunity cost of decreased interest and short-term investment income due to lower balances of cash and short-term investments liquidated to fund the cash portion of the purchase price. Sparton paid cash for a portion of the Astro acquisition price and paid cash to retire Astro’s line-of-credit borrowings.

(g)		To record interest expense on the debt that Sparton incurred to finance the acquisition, and to reduce interest expense on Astro’s line-of-credit borrowings that Sparton retired at closing of the acquisition. Such interest expense includes amortization on a straight-line basis of the purchase discount of $151,000 assigned to the Ohio bonds assumed from Astro.

(h)		To charge to costs of goods assumed to be sold entirely during the year ended June 30, 2005, a purchase price allocation adjustment to the fair value of inventories acquired.
