(ECD or the Company) have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and disclosures normally included in ECDs annual financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to SEC rules and regulations. The information presented as of December 31, 2006 and for the three-month and six-month periods ended December 31, 2006 is unaudited, but includes all adjustments that ECDs management believes to be necessary for the fair presentation of results for the periods presented. The results for interim periods are not necessarily indicative of results to be expected for the year. These consolidated condensed financial statements
should be read in conjunction with ECDs audited financial statements for the fiscal year ended June 30, 2006, which are included as part of ECDs Annual Report on Form 10-K for the fiscal year ended June 30, 2006. Nature of Business ECD invents, designs, develops and commercializes materials, products and production processes for the alternative energy generation, energy storage and information technology markets. The consolidated financial statements include the accounts of ECD and its 100%-owned manufacturing and sales subsidiary United Solar Ovonic Corp. (United Solar Ovonic) and its approximately 91%-owned subsidiary Ovonic Battery Company, Inc. (Ovonic Battery) (collectively the Company). No minority interest related to Ovonic Battery is recorded in the consolidated financial statements because there is no additional funding requirement by the minority shareholders. The Company has a number of strategic alliances and, as of December 31, 2006, has two major investments accounted for using the equity method: (i) Cobasys LLC, a joint venture between Ovonic Battery and a subsidiary of Chevron Corporation, Chevron Technology Ventures LLC (Chevron), each having 50% interest in the joint venture and (ii) Ovonyx, Inc., a 39.5%-owned (31.3% on a fully diluted basis
after giving effect to exercise of stock options and warrants) joint venture with Mr. Tyler Lowrey, Intel Capital, and other investors. See Note D for discussions of all of the Companys major joint ventures and investments.   7     Table of Contents  ENERGY CONVERSION DEVICES, INC. and SUBSIDIARIES Notes to Consolidated Financial Statements NOTE A  Summary of Accounting Policies (Continued) At December 31 and June 30, 2006, the Companys investment in Cobasys was recorded at zero. At December 31, 2006 and June 30, 2006, the Companys investment in Ovonyx was recorded at $200,000 and zero, respectively. The Company will continue to carry its investment in each of these joint ventures at zero or the amount of its cash investment until the venture becomes sustainably profitable, at which time the Company will start to recognize over a period of years its share, if any, of the thenequity of each of the ventures, and will recognize its share of each ventures profits or losses on the equity method of accounting. To the extent that the Company has made contributions other than technology, it recognizes its proportionate share of any losses until the investment reaches zero. Intellectual property, including patents, resulting from the Companys investments in its technologies, is valued at zero in the balance sheet. Intellectual property provides the foundation for the creation of the important strategic alliances whereby the Company provides intellectual property and patents and joint venture partners provide cash. While the Company believes that it has no obligation to fund any losses that its joint ventures incur beyond the Companys investment, the Company has decided to provide limited funding to certain of its joint ventures. Upon consolidation, all intercompany accounts and transactions are eliminated. Any profits on intercompany transactions are eliminated to the extent of the Companys ownership percentage. Discontinued Operations In December 2005, the Company, as part of its restructuring plan, sold Ovonic Batterys metal hydride materials manufacturing business to Great Western Technologies Inc. (GWTI) for installment payments totaling $906,000, with an initial payment of $453,000; a second payment of $271,800 received on December 12, 2006; and a third payment of $181,200 (discounted to $167,087) to be made no later than December 12, 2007. The Company recorded a gain on this sale of approximately $740,000 in the year ended June 30, 2006. In addition, GWTI assumed the lease obligations for two of Ovonic Batterys manufacturing plants. Ovonic Battery is subleasing a portion of one of these facilities.   8     Table of Contents   ENERGY CONVERSION DEVICES, INC. and SUBSIDIARIES Notes to Consolidated Financial Statements NOTE A  Summary of Accounting Policies (Continued) For the three months and six months ended December 31, 2005, the Company recorded the following results of its metal hydride materials manufacturing business as a discontinued operation in accordance with Statement of Financial Accounting Standards (SFAS) No. 144: Three Months EndedDecember 31, 2005

313,979 Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP) requires management to make estimates and assumptions that affect amounts reported therein. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may be based upon amounts that differ from those estimates. Preproduction Costs The Company classifies costs in preparation for its new manufacturing facilities and equipment as preproduction costs. These costs include training of new employees, supplies and other costs for the new manufacturing facilities in advance of the commencement of manufacturing. Reclassifications Certain prior period amounts have been reclassified to conform with the 2007 presentation.   9     Table of Contents   ENERGY CONVERSION DEVICES, INC. and SUBSIDIARIES Notes to Consolidated Financial Statements NOTE A  Summary of Accounting Policies (Continued) Short-Term Investments The Company has evaluated its investment policies consistent with SFAS No. 115, Accounting for Certain Investments in Debt and Equity Securities, and determined that all of its investment securities are classified as available-for-sale.

3,644,769 ECD has three shareholder-approved plans: the 1995 Non-Qualified Stock Option Plan (the 1995 Plan) pursuant to which 2,000,000 shares were reserved for grant, the 2000 Non-Qualified Stock Option Plan (the 2000 Plan) pursuant to which 3,000,000 shares were reserved for grant and the 2006 Stock Incentive Plan (the 2006 Plan) pursuant to which 1,000,000 shares are to be reserved for future grants. The 1995 and 2000 Plans authorize the granting of stock options at such exercise prices and to such employees, consultants and other persons as the Compensation Committee appointed by the Board of Directors (the Compensation Committee) shall determine. The exercise period for stock options generally may not exceed 10 years from the date of grant. We issue new shares to satisfy stock option exercises. Under the terms of the 1995 Plan, 40% of the option becomes exercisable six months after grant date, with an additional 30% becoming exercisable at the commencement of 18 and 30 months following the grant date. The 1995 Plan expired on January 26, 2005 and no additional grants will be made under this Plan. Under the terms of the 2000 Plan, 40% of the option becomes exercisable one year after grant date, with an additional 20% becoming exercisable after each of the second, third and fourth anniversaries of the grant date. Effective November 14, 2006, the date ECD stockholders approved the 2006 Stock Incentive Plan, ECD will not grant any additional options under the 2000 Plan. The 2006 Plan authorizes the grant of stock options, including nonqualified and incentive options, stock appreciation rights, restricted stock, restricted stock units, performance shares and performance units to officers, other employees, nonemployee directors, consultants, advisors, independent contractors and agents of ECD and its   12     Table of Contents   ENERGY CONVERSION DEVICES, INC. and SUBSIDIARIES Notes to Consolidated Financial Statements NOTE A  Summary of Accounting Policies (Continued) subsidiaries. The Committee will determine the conditions to the exercisability of each option and the terms relating to the exercise or cancellation of an option upon a termination of employment or service, but no option shall fully vest in less than four years, with no more than 40% vesting in the first year following the award, no more than a total of 60% of the option vesting by the end of the second year following the award and no more than a total of 80% of the option vesting by the end of the third year following the award. Each option will be exercisable for no more than ten years after its date of grant, except that an incentive option granted to a participant owning more than 10% of our voting shares will be exercisable for no more than five years after its date of grant. As of December 31, 2006 and June 30, 2006, ECD had outstanding a warrant for the purchase of 400,000 shares of Common Stock granted pursuant to a Common Stock Warrant Agreement entered into in March 2000. This warrant is exercisable on or prior to March 10, 2010 at $22.93 per share. Total net stock-based compensation expense is attributable to the granting of and the remaining requisite service periods of stock options previously granted. Compensation expense attributable to net stock-based compensation in the three and six months ended December 31, 2006 was $309,000 and $901,000, respectively, and in the three and six months ended December 31, 2005 was $403,000 and $903,000, respectively, increasing both basic and diluted loss per share by $.01 and $.02 for the three months and six months ended December 31, 2006, respectively, and by $.01 and $.03 for the three months and six months ended December 31, 2005, respectively. As of December 31, 2006, the total unrecognized compensation cost related to nonvested stock grants was $1,298,000 and the related weighted-average period over which it is expected to be recognized is approximately 1.28 years.

The intrinsic value of a stock option is the amount by which the current market value of the underlying stock exceeds the exercise price of the option.
 In September 1993, ECD entered into Stock Option Agreements with Stanford R. Ovshinsky and Dr. Iris M. Ovshinsky granting each an option to purchase 150,000 shares (391,294 as of December 31, 2006) and 100,000 shares (130,465 as of December 31, 2006), respectively. The weighted average exercise price of the outstanding stock options is $17.06 per share at December 31, 2006. The Stock Option Agreements provided for periodic antidilution protection adjustments based on changes in the number of outstanding shares of ECD Common Stock. In June 2005, the Agreements were amended by deleting the antidilution protection adjustment provision, and no further options will be granted under the Agreements. In consideration of the agreements by Mr. and Dr. Ovshinsky to such amendment, the Companys Compensation Committee approved the grant of options to Mr. Ovshinsky (100,000 shares) and to Dr. Ovshinsky (65,000 shares) under the Companys 2000 Non-Qualified Stock Option Plan. Upon the death of Dr. Ovshinsky on August 16, 2006, and pursuant to the terms of the Stock Option Agreements and our stock   14     Table of Contents   ENERGY CONVERSION DEVICES, INC. and SUBSIDIARIES Notes to Consolidated Financial Statements NOTE A  Summary of Accounting Policies (Continued) option plans, options owned by Dr. Ovshinsky were transferred to her estate, of which her husband, Mr. Ovshinsky, is the executor.

The vesting schedule provides for quarterly vesting of 23,000 shares at the beginning of each quarter commencing July 1, 2006 through October 1, 2010 with 16,000 shares vesting on December 31, 2010. During the three months and six months ended December 31, 2006, 23,000 and 46,000 shares, respectively, became vested at a weighted average grant date fair value of $10.688 per share. Basic and Diluted Net Loss Per Share Basic net loss per common share is computed by dividing the net loss by the weighted average number of common shares outstanding. ECD uses the treasury stock method to calculate diluted earnings per share. Potential dilution exists from stock options and warrants. Weighted average number of shares outstanding and basic and diluted net loss per share for the three months and six months ended December 31 are computed as follows: Three Months EndedDecember 31,

Additional securities of 6,317 and 18,400 for the three and six months ended December 31, 2006, respectively, were excluded from the 2006 calculation of weighted average shares of potential dilutive securities. Since the exercise prices exceeded the average market price of ECDs Common Stock during these periods, these securities would have been antidilutive regardless of the Companys net income or loss. Due to the Companys net loss, the 2005 weighted average shares of potential dilutive securities of 2,189,439 and 2,378,124 for the three months and six months ended December 31, 2005, respectively, were excluded from the calculations of diluted net loss per share, as inclusion of these securities would have been antidilutive to the net loss per share. Recent Pronouncements In February 2006, the Financial Accounting Standards Board (FASB) issued SFAS No. 155, Accounting for Certain Hybrid Instruments. This statement allows financial instruments that have embedded derivatives to be accounted for as a whole (eliminating the need to bifurcate the derivative from its host) if the holder elects to account for the whole instrument on a fair value basis. This statement is effective for all financial instruments acquired or issued after the beginning of an entitys first fiscal year that begins after September 15, 2006. The effect of SFAS No. 155 is not material. In June 2006, the FASB issued FASB Interpretation No. 48 (FIN 48), Accounting for Uncertainty in Income Taxes,  an interpretation of FASB Statement No. 109, Accounting for Income Taxes  which clarifies the accounting for uncertainty in income taxes. FIN 48 prescribes a recognition threshold and measurement attributed for the financial statement recognition and measurement of a tax position taken, or expected to be taken, in a tax return. The interpretation requires that the Company recognize in the financial statements the impact of a tax position if that position is more likely than not of being sustained on audit, based on the technical merits of the position. FIN 48 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods and disclosure. The provisions of FIN 48 are effective for fiscal years
beginning after December 15, 2006 with the cumulative effect of the change in accounting principle recorded as an adjustment to opening accumulated deficit. The Company is currently evaluating the impact of adopting FIN 48 on its financial statements.   18     Table of Contents   ENERGY CONVERSION DEVICES, INC. and SUBSIDIARIES Notes to Consolidated Financial Statements NOTE A  Summary of Accounting Policies (Continued) In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements, which defines fair value and establishes a framework for measuring fair value. SFAS No. 157 does not require any new fair value measurements, but provides guidance on how to measure fair value by providing a fair value hierarchy used to classify the source of the information. This statement is effective for financial statements issued for fiscal years beginning after November 15, 2007. The Company is currently assessing the potential impact that the adoption of SFAS No. 157 will have on our financial statements. In September 2006, the SEC issued Staff Accounting Bulletin (SAB) No. 108, Considering the Effects of Prior Year Misstatements when Quantifying Current Year Misstatements. SAB No. 108 requires analysis of misstatements using both an income statement (rollover) approach and a balance sheet (iron curtain) approach in assessing materiality and provides for a one-time cumulative effect transition adjustment. SAB No. 108 is effective for fiscal years ending after November 15, 2006. The effect of SAB No. 108 is not material.

 In July 2004, ECD and Cobasys entered into a settlement agreement with Matsushita Electric Industrial Co. (MEI), Panasonic EV Energy Co., Ltd. (PEVE), and Toyota Motor Corporation with respect to patent infringement disputes and counterclaims involving nickel metal hydride (NiMH) batteries before the International Chamber of   22     Table of Contents   ENERGY CONVERSION DEVICES, INC. and SUBSIDIARIES Notes to Consolidated Financial Statements NOTE D  Joint Ventures and Investments (Continued) Commerce, International Court of Arbitration. Under the terms of the settlement, no party admitted any liability. As part of the settlement, ECD and its subsidiary, Ovonic Battery, received a $10,000,000 license fee from MEI and PEVE. This fee was recorded as a deferred patent license fee in July 2004 and is being amortized to income over 10.5 years. The Company recognized $238,000 as revenues from license agreements in each of the three months ended December 31, 2006 and 2005 and $476,000 as revenues from license agreements in each of the six months ended December 31, 2006 and 2005 in connection with the amortization of this fee. Ovonyx In October 2002, ECD entered into a license with Ovonyx pursuant to which ECD licensed, on an exclusive, royalty-bearing basis, from Ovonyx technology it had previously contributed to Ovonyx.  ECD made a $1,000,000 upfront royalty payment and paid $150,000 and $200,000 annual minimum royalty payments in December 2005 and December 2006, respectively.  ECD has made aggregate royalty payments of $1,500,000 through December 2006 (including the upfront royalty payment), which it records as capital investments.  ECD has made no other capital investments in Ovonyx.

Managements Discussion and Analysis of Financial Condition and Results of Operations
 This section summarizes significant factors affecting the Companys consolidated operating results, financial condition and liquidity for the three and six months ended December 31, 2006. This section should be read in conjunction with the Companys Consolidated Financial Statements and related notes appearing elsewhere in this report and the Companys filed Annual Report on Form 10-K for the year ended June 30, 2006. Overview We invent, design, develop and commercialize materials, products and production processes for the alternative energy generation, energy storage and information technology markets. Our materials, products and production processes originate from the pioneering work of Mr. Stanford R. Ovshinsky, principal inventor and our President, Chief Scientist and Technologist, in materials science at the atomic (or nanostructure) level, principally amorphous and disordered materials. We manufacture for commercial sale thin-film photovoltaic (PV) modules, which account for substantially all of our product sales, as well as manufacture and sell positive electrode nickel hydroxide battery materials, and license our NiMH battery technology, which is used in commercial products. Our principal joint ventures  Cobasys LLC and Ovonyx, Inc.  are also commercializing our NiMH battery and Ovonic
Universal Memory (OUM) technologies, and battery products manufactured by Cobasys are commercially available. We continue our research and development activities for our emerging technologies in order to bring these technologies to full-scale commercialization. We seek third-party funding to offset our funding requirements for these activities. These business activities represent application of our overall business strategy to commercialize our materials, products and production processes internally and through third-party relationships, such as licenses and joint ventures. Accordingly, our results reflect our approach to commercialization of a particular technology, as well as the commercial readiness of that technology, and consideration should be given to the following key factors when reviewing our results for the periods discussed: 
We are engaged in full-scale manufacturing and sale of our PV products through our United Solar Ovonic segment, and our consolidated financial results are driven primarily by the performance of this segment. Our United Solar Ovonic segment accounted for 84% and 86% of our total revenue in the three and six months ended December 31, 2006, respectively, and 89% and 86% in the three and six months ended December 31, 2005, respectively. Additionally, our United Solar Ovonic segment generated operating income of $1,150,000 and $2,620,000 in the three months and six months ended December 31, 2006, respectively, while our other two segments had combined operating losses of $8,488,000 and $16,771,000, respectively (which we seek to fund as described below). Given the projected growth of our photovoltaic business (see below) relative to our other business segments, our overall    30     Table of Contents   success in the foreseeable future will be aligned primarily with the performance of our United Solar Ovonic segment and subject to the risks of that business. 
We are rapidly expanding manufacturing capacity for our PV products to meet the rapid growth in the alternative energy generation market in general and the solar market in particular, and we will require significant capital to fund this expansion. We are expanding our PV module manufacturing capacity to an expected capacity exceeding 300MW per annum by 2010. In December 2006, we placed in service the manufacturing equipment for our new Auburn Hills 2 facility, thereby increasing our aggregate manufacturing capacity to 58MW. This manufacturing facility will be ramping up to full capacity in Fall 2007. We are also presently constructing two 60MW per annum PV cell manufacturing facilities in Greenville, Michigan, which are expected to begin operation in late 2007 and mid-2008. We are funding the initial phases of our manufacturing capacity expansion with the proceeds from our
March 2006 common stock offering. We will require additional funding for subsequent phases through 2010, which we may obtain from equity or debt financing, business agreements and other sources.
We are commercializing our NiMH battery and OUM technologies principally through unconsolidated joint ventures, and we account for our interests in these joint ventures under the equity method of accounting. Our principal joint venturesCobasys and Ovonyxwere founded upon technologies that we pioneered, and then formed to further develop and commercialize these technologies. In each case, we participate in the business as equity holders but do not directly manage or have a controlling interest in the entity. We have not reported any earnings or losses from Cobasys because our only contributions to Cobasys have been noncash items, including intellectual property and know-how. We have contributed intellectual property and cash (through royalty payments) to Ovonyx, and have, as of December 31, 2006, recognized equity losses of $1,300,000 related to our Ovonyx investment. Our
interest in Cobasys was recorded at zero on our balance sheet at December 31, 2006 and June 30, 2006, respectively, and our investment in Ovonyx was recorded at $200,000 and zero at December 31, 2006 and June 30, 2006, respectively. See Note A, "Summary of Accounting Policies," and Note D, "Joint Ventures and Investments," of the Notes to our Consolidated Financial Statements, for additional details regarding our accounting for our investments in Cobasys and Ovonyx.
We are continuing to further develop our emerging technologies. We continue to generate losses and require substantial additional funding, as we seek to bring these technologies to commercial product status. We have successfully brought our PV and NiMH technologies from pioneering technologies to commercial products, and Ovonyx has been collaborating successfully with a number of semiconductor companies to commercialize OUM. We are utilizing a similar strategy for our current emerging technologies, such as Ovonic solid hydrogen systems, Ovonic metal hydride fuel cell, Ovonic photonic devices and   31     Table of Contents   Ovonic cognitive computer (including the Ovonic quantum control device), as we engage in research and development activities to define marketable technologies that can result in commercial products. We expect to record losses associated with these activities at this stage while we seek to offset our funding requirements with third-party funding, including strategic alliances and government contracts. Our third-party funding for these activities has declined in recent years, principally due to the restructuring of certain strategic relationships and completion of certain government contracts, and we are presently actively seeking new government contracts and additional strategic funding for several of our emerging technologies. Key indicators of Financial Condition and Operating Performance. In evaluating our business, we use operating income and cash flow from operations as key performance metrics. We also use production capacity, measured in megawatt (MW) per annum, as a key performance metric for our United Solar Ovonic segment, particularly in connection with the manufacturing capacity expansion in this segment.    32     Table of Contents   Results of Operations The period comparisons contained in this section exclude discontinued operations (see Other Income/Expense below).

Principally the sales ($24,063,000 and $14,323,000 for the three months ended December 31, 2006 and 2005, respectively) by ECD to United Solar Ovonic of the solar PV module machinery and equipment which is eliminated in consolidation. The ECD revenues, excluding primarily the aforementioned sales to United Solar Ovonic, were $1,138,000 and $1,142,000 for the three months ended December 31, 2006 and 2005, respectively.
 Our loss from operations in 2006 was higher than 2005. Operating results in our United Solar Ovonic segment were impacted by decreased product sales, initial low production volumes at our Auburn Hills 2 manufacturing facility that was placed in service in December 2006, and associated preproduction costs. The operating loss in our ECD segment increased due principally to increased product development and general and administrative expenses. Ovonic Batterys operating results improved due to a $750,000 reduction in 2006 in a product warranty accrual, increased product sales and increased royalties.    33     Table of Contents   United Solar Ovonic Segment Three Months EndedDecember 31,2006

 Our United Solar Ovonic segments operating income decreased in 2006 versus 2005, due to decreased product sales and preproduction expenses related to our new Auburn Hills 2 manufacturing facility. The decreases in revenues and expenses in 2006 were primarily attributable to decreased volume of PV products ($4,000,000), partially offset by more favorable pricing mix ($300,000). The decreased volume is primarily attributable to the expected temporary, substantial decline for fiscal year 2007 of sales of our PV modules to Solar Integrated Technologies Inc. (SIT), which we were unable to fully reallocate during the quarter to existing customers or offset through additional sales. SIT recently completed an equity offering and used a portion of the proceeds to pay its outstanding payables to us. We now expect SIT to resume purchasing our PV modules during this fiscal year. Gross profit margin on product sales decreased to 16.0% in 2006 from 21.2% in 2005. As we expand our manufacturing capacity, our gross profit margins are impacted by early lower production volumes as we ramp up production to full capacity at our new manufacturing facilities. Our gross profit margin was primarily impacted during 2006 by production ramp up at our Auburn Hills 2 manufacturing facility. Gross margins for the remainder of fiscal 2007 will likewise be impacted as this manufacturing facility ramps up   34     Table of Contents   to full capacity by Fall 2007. Fiscal 2008 gross margins will be impacted by production ramp up at our Greenville facilities which are expected to be placed in service in late 2007 and mid-2008. Operating, general and administrative expenses and patent expenses decreased due principally to a $1,000,000 reduction in the allowance for doubtful accounts at December 31, 2006 (associated with the payment from SIT), partially offset by increased costs for manufacturing capacity expansion activities ($26,000) associated with our new Auburn Hills facility. The combined product development and research expenses increased to $1,846,000 in 2006 from $1,508,000 in 2005 due principally to increased activities under existing product development agreements with the U.S. Air Force (to develop new products for space and airship applications), Lockheed Martin and the National Renewable Energy Laboratory (NREL). In addition, we continue to incur product development and research expenses to improve the throughput of our PV cell manufacturing equipment, reduce the cost of production and increase the sunlight-to-electricity conversion efficiency of our PV modules.

   35     Table of Contents    Our Ovonic Battery segments operating loss decreased in 2006 due to a $750,000 reduction in 2006 in a product warranty accrual, increased product sales and increased royalties. Product sales, which include sales of our positive electrode nickel hydroxide materials, increased in 2006 as compared to 2005 due to increased nickel hydroxide sales to our largest customer ($667,000), partially offset by reduced sales to our Rare Earth Ovonic joint venture (zero in 2006 compared to $320,000 in 2005). Positive electrode nickel hydroxide sales increased to $1,209,000 in 2006 from $542,000 in 2005. Cost of sales decreased due to the reduced sales to our Rare Earth Ovonic joint venture, partially offset by costs associated with the increased level of nickel hydroxide sales in 2006. Royalties increased in 2006 as compared to 2005, due principally to a $727,000 reduction in transportation royalties recognized in 2005 based upon a royalty report received in 2005 (see Note H, Product Sales, Royalties, Revenues from Product Development Agreements, Nonrefundable Advance Royalties and License Agreements, of the Notes to our Consolidated Financial Statements). Revenues from license agreements were the same in 2006 as in 2005, representing amortization over 10.5 years of a $10,000,000 payment received in a July 2004 settlement of certain patent infringement disputes (see Note D, Joint Ventures and Investments, of the Notes to our Consolidated Financial Statements). The combined product development and research expenses decreased slightly in 2006 to $2,038,000 from $2,217,000 in 2005, as we continued to develop and enhance our NiMH battery technologies. Revenues from product development agreements, which increased in 2006 as compared to 2005, represent research and development support for our Cobasys joint venture. Operating, general and administrative expenses and patent expenses decreased in 2006 principally due to a $750,000 reduction in 2006 in the product warranty accrual attributable to the equipment previously supplied to our Rare Earth Ovonic joint venture, partially offset by increased patent defense costs.    36     Table of Contents   Energy Conversion Devices Segment Three Months EndedDecember 31,2006

Represents sales ($24,063,000 and $14,323,000 for the three months ended December 31, 2006 and 2005, respectively) of production equipment by our Production Technology and Machine Building Division to our United Solar Ovonic segment in connection with its manufacturing expansion. These product sales are eliminated in consolidation.
 Our ECD segment had an increased operating loss in 2006 as compared to 2005 due to increased product development and research and operating, general and administrative and patent expenses. Substantially all of our product sales ($24,063,000) are sales of production equipment from our Production Technology and Machine Building Division to our United Solar Ovonic segment in connection with its manufacturing expansion. These product sales are eliminated in consolidation. Product sales and cost of product sales increased due to sales of production equipment for this expansion. Royalties, consisting principally of royalties related to our Ovonic photonic devices technologies, decreased principally due to a one-time adjustment in 2006 of royalties payable by one of our licensees.   37     Table of Contents   Other operating revenues consist primarily of services, facilities and miscellaneous administrative and laboratory and machine shop services provided to some of our unconsolidated affiliates. The combined product development and research expenses increased to $6,878,000 in 2006 from $6,091,000 in 2005, as we continued to develop our emerging technologies for future applications, including our Ovonic solid hydrogen storage systems, Ovonic metal hydride fuel cell, Ovonic photonic devices and Ovonic cognitive computer (including the Ovonic quantum control device) technologies. Revenues from product development agreements decreased primarily due to the completion of programs in 2005 with NREL and reduced activities with the National Institute of Standards and Technology (NIST) related to our Ovonic photonic devices technology. Operating, general and administrative expenses and patent expenses were higher in 2006 compared to 2005 due to costs incurred to support further expansion, plus increased patent expenses. Other Income/Expense Other income (net) increased to $4,963,000 in 2006 from $756,000 in 2005, primarily due to higher interest income ($4,964,000 in 2006 compared to $801,000 in 2005) relating to increased funds available for investment. Discontinued operations reflects our metal hydride manufacturing materials business, which we sold in December 2005 as part of our restructuring plan (see Note A, Summary of Accounting Policies, of the Notes to our Consolidated Financial Statements).    38     Table of Contents   Six Months Ended December 31, 2006 compared to Six Months Ended December 31, 2005 The table below summarizes each of the Companys business segments operating results (in thousands) for the six months ended December 31, 2006 and 2005.

Principally the sales ($42,220,000 and $24,348,000 for the six months ended December 31, 2006 and 2005, respectively) by ECD to United Solar Ovonic of the solar PV module machinery and equipment which is eliminated in consolidation. The ECD revenues, excluding primarily the aforementioned sales to United Solar Ovonic, were $2,612,000 and $2,076,000 for the six months ended December 31, 2006 and 2005, respectively.
 Our loss from operations in 2006 was higher than 2005. Operating results in our United Solar Ovonic segment decreased due principally to the initial low production volumes at our new Auburn Hills 2 manufacturing facility that was placed in service in December 2006 and the preproduction costs associated with Auburn Hills 2. The operating loss in our ECD segment increased due principally to increased product development and general and administrative expenses. Ovonic Batterys operating results improved due to a $750,000 reduction in 2006 in a product warranty accrual.   39     Table of Contents   United Solar Ovonic Segment Six Months EndedDecember 31,2006

  Our United Solar Ovonic segments operating income decreased in 2006 versus 2005 due to the impact of early lower production volumes as we ramp up production to full capacity at our new Auburn Hills 2 manufacturing facility and the preproduction expenses associated with the startup of this facility. The increases in revenues and expenses in 2006 were primarily attributable to increased product sales due to a more favorable pricing mix ($2,000,000), partially offset by decreased volume ($1,800,000) of PV products. The decreased volume is primarily attributable to the expected temporary, substantial decline for fiscal year 2007 of sales of our PV modules to SIT, which we were unable to fully reallocate during the quarter to existing customers or offset through additional sales. SIT recently completed an equity offering and used a portion of the proceeds to pay its outstanding payables to us. We now expect SIT to resume purchasing our PV modules during this fiscal year. Gross profit margin on product sales remained the same (20%) in both 2006 and 2005. As we expand our manufacturing capacity, our gross profit margins are impacted by higher costs associated with production volumes as we ramp up production to full capacity at our new manufacturing facilities. Our gross profit margin was primarily impacted during 2006 by production ramp up at our Auburn Hills 2 manufacturing facility. Gross margins for the remainder of fiscal 2007 will likewise be impacted as this manufacturing facility ramps up to full capacity by Fall 2007. Fiscal 2008 gross margins    40     Table of Contents   will be impacted by production ramp up at our Greenville facilities, which are expected to be placed in service in late 2007 and mid-2008. Operating, general and administrative expenses and patent expenses increased due principally to increased production volume and to support manufacturing capacity expansion activities ($969,000) associated with our new Auburn Hills 2 manufacturing facility. The combined product development and research expenses increased to $3,651,000 in 2006 from $3,069,000 in 2005 due principally to increased activities under product development agreements with the U.S. Air Force (to develop new products for space and airship applications), Lockheed Martin and NREL. In addition, we continue to incur product development and research expenses to improve the throughput of our PV cell manufacturing equipment, reduce the cost of production and increase the sunlight-to-electricity conversion efficiency of our PV modules.

(2,769
)  Our Ovonic Battery segments operating loss decreased in 2006 due to a $750,000 reduction in 2006 in the product warranty accrual and reduced expenses in 2006. Product sales, which include sales of our positive electrode nickel hydroxide materials, decreased in 2006 as compared to 2005 due to reduced sales to our Rare Earth   41     Table of Contents   Ovonic joint venture (zero in 2006 compared to $718,000 in 2005). Positive electrode nickel hydroxide sales increased to $1,925,000 in 2006 from $1,264,000 in 2005. Costs of sales of these products increased to $1,543,000 in 2006, from $1,406,000 in 2005, reflecting higher volume of sales offset by the aforementioned reduction ($666,000) in 2006 in the Rare Earth Ovonic program. Royalties increased slightly in 2006 as compared to 2005 due to increases in both consumer and transportation royalties as the use of our technologies in both of these areas increased. Revenues from license agreements were the same in 2006 as in 2005, representing amortization over 10.5 years of a $10,000,000 payment received in a July 2004 settlement of certain patent infringement disputes (see Note D, Joint Ventures and Investments, of the Notes to our Consolidated Financial Statements) plus an additional license agreement of $20,000 in each period. The combined product development and research expenses decreased slightly to $4,091,000 in 2006 from $4,396,000 in 2005, as we continued to develop and enhance our NiMH battery technologies. Revenues from product development agreements decreased principally due to reduced research and development support for our Cobasys joint venture as it transitioned toward product development and production ($345,000 in 2006 compared to $556,000 in 2005). Operating, general and administrative expenses and patent expenses decreased in 2006 due to a $750,000 reduction in 2006 in the product warranty accrual expenses in connection with the Rare Earth Ovonic joint venture, partially offset by increased patent defense costs.    42     Table of Contents   Energy Conversion Devices Segment Six Months EndedDecember 31,2006

Represents sales ($42,220,000 and $24,348,000 for the periods ended 2006 and 2005, respectively) by ECD to United Solar Ovonic of the solar PV module machinery and equipment which is eliminated in consolidation.
 The ECD segment had an increased operating loss in 2006 versus 2005 primarily due to increased product development and operating, general and administrative expenses. Substantially all of our product sales ($42,220,000) are sales of production equipment by our Production Technology and Machine Building Division to our United Solar Ovonic segment in connection with its manufacturing expansion that are eliminated in consolidation. Product sales and cost of product sales increased due to commencement of production and sales of production equipment for this expansion. Royalties, consisting principally of royalties related to our Ovonic photonic devices technologies, decreased principally due to a one-time adjustment in 2006 of royalties payable by one of our licensees.   43     Table of Contents   Other operating revenues consist primarily of services, facilities and miscellaneous administrative and laboratory and machine shop services provided to some of our unconsolidated affiliates. The combined product development and research expenses increased to $13,855,000 in 2006 from $12,833,000 in 2005, as we continued to develop our emerging technologies for future applications, including our Ovonic solid hydrogen storage systems, Ovonic metal hydride fuel cell, Ovonic photonic devices and Ovonic cognitive computer (including the Ovonic quantum control device) technologies. Revenues from product development agreements increased primarily due to increases in existing programs in 2006 for biofuel reformation with Xcel Energy and organic electroluminescent devices with United States Display Consortium, partially offset by the completion of the program in 2005 with NREL and reduced activities with NIST related to our Ovonic photonic devices technology. Operating, general and administrative expenses and patent expenses were higher in 2006 compared to 2005 due to costs incurred to support further expansion, plus increased patent expenses ($171,000). Other Income/Expense Other income (net) increased to $10,005,000 in 2006 from $1,332,000 in 2005, primarily due to higher interest income ($10,234,000 in 2006 compared to $1,598,000 in 2005) relating to increased funds available for investment. Discontinued operations reflects our metal hydride manufacturing materials business, which we sold in December 2005 as part of our restructuring plan (see Note A, Summary of Accounting Policies, of the Notes to our Consolidated Financial Statements). Liquidity and Capital Resources Our primary liquidity needs are to fund capital expenditures associated with expansion of our United Solar Ovonic segments manufacturing capacity and support our working capital requirements, as well as to fund the further development of our emerging technologies in our other segments and general corporate purposes. Our principal sources of liquidity are cash, cash equivalents and short-term investments, and related interest income, (which principally represent the proceeds from our March 2006 common stock offering) and cash flows from operating activities at our United Solar Ovonic segment. We believe that cash, cash equivalents and short-term investments and cash flows from operations will be sufficient to meet our liquidity needs for the foreseeable future. We intend to use the net proceeds from our March 2006 common stock offering for our PV manufacturing expansion, which includes
construction of two 60MW manufacturing facilities in Greenville, Michigan, an assembly plant in Tijuana, Mexico, and related assembly equipment, and general corporate purposes. We will require additional funding for this expansion through 2010, and for emerging technologies and general corporate   44     Table of Contents   purposes, which we may obtain from equity and debt financing, business agreements and other sources. As of December 31, 2006, we had $351,295,000 consolidated cash, cash equivalents, and short-term investments consisting of certificates of deposits, variable rate corporate bonds (VRCBs), auction rate certificates (ARCs), corporate notes and money market funds. All short-term investments are classified as available-for-sale. These short-term investments have maturities up to 36 months, except for the ARCs which have maturities from 20 to 40 years. Both the VRCBs and ARCs resemble short-term instruments due to the periodic interest rate reset and put options. At December 31, 2006, we had consolidated working capital of $366,192,000. Cash Flows Net cash provided by operating activities was $8,724,000 in 2006 as compared to net cash used in operations of $12,055,000 in 2005. The major factors contributing to this improvement in cash pertaining to operations were a reduced net loss ($6,987,000) reflecting increased interest income and improved cash flow from operations at our United Solar Ovonic segment. In addition, there were improved collections of accounts receivable ($8,788,000), including the collection of the SIT accounts receivable, an increase in accounts payable and accrued expenses ($12,024,000), partially offset by an increase in inventories ($7,168,000). The increase in inventories in the six months ended December 31, 2006, is due to the build-up of inventories for the ramp up of the new United Solar Ovonic plant, decreased product sales at United Solar Ovonic in the second quarter, and future sales orders. Net cash used in investing activities was $161,051,000 in 2006 as compared to $16,113,000 used in 2005. This increase was due to net purchases ($90,590,000) of investments plus purchases ($70,261,000) of property, plant and equipment in 2006. This increase in capital spending was principally associated with expansion of our United Solar Ovonic segments manufacturing capacity. Net cash provided by financing activities was $8,005,000 in 2006 as compared to $10,899,000 in 2005 due to reduced exercise of stock options in 2006. For details of our cash flows, see the Consolidated Statements of Cash Flows in our Consolidated Financial Statements. Contractual Obligations The Company, in the ordinary course of business, enters into purchase commitments for raw materials. The Company also enters into purchase commitments for capital equipment, including subcontracts for the purchase of components for the new solar cell manufacturing equipment constructed for the new Auburn Hills facility and being constructed for Greenville facilities in Michigan. The Companys total obligations under purchase commitments at December 31, 2006, were $94,872,000 ($82,993,000 of which   45     Table of Contents   was due within one year and $11,879,000 thereafter) compared to $42,210,000 at June 30, 2006. The increase in purchase commitments is primarily due to additional commitments to purchase steel for the new Auburn Hills facility and construction and equipment commitments for the new Greenville facilities. Short-term Borrowings As of December 31, 2006, we had a line of credit with LaSalle Bank Midwest N.A. in the amount of $4,000,000. This line of credit provides a mechanism for obtaining letters of credit and entering into future foreign exchange transactions. The line of credit, which expires on August 31, 2007, is secured by a security interest in inventory and receivables and contains certain covenants, including a minimum $20,000,000 liquidity covenant. At December 31, 2006, the Company had outstanding letters of credit of $2,161,000 against the line of credit. Joint Ventures We do not presently provide funding to either of our principal joint ventures, Cobasys and Ovonyx. Chevron, our partner in Cobasys, is presently funding Cobasys operations and is committed under the Cobasys operating agreement to continue funding approved operating budgets through December 2007. Beginning in January 2008, the joint venture partners will be required to make capital contributions as necessary to fund approved operating budgets in proportion to their percentage interests, subject to the terms of the Cobasys operating agreement. Ovonyx does not currently require financial support because it has generated sufficient funds for its operations through licensing activities. Critical Accounting Estimates and Significant Accounting Policies Our significant accounting policies are more fully described in Note A, Summary of Accounting Policies, to our Consolidated Financial Statements. Certain of our accounting policies require management to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates and assumptions are based on our historical experience, the terms of existing contracts, our evaluation of trends in the industry, information provided by our customers and suppliers and information available from other outside sources, as appropriate. However, they are subject to an inherent degree of uncertainty. As a result, actual results in these areas may differ significantly from our estimates. We consider an accounting estimate to be critical if it requires us to make assumptions about matters that were uncertain at the time the estimate was made and changes in the estimate would have had a significant impact on our consolidated financial position or results of operations.   46     Table of Contents   Allowance for Uncollectible Accounts Our allowance for uncollectible accounts was $605,000 at December 31, 2006, from $691,000 at June 30, 2006. See Note B, Accounts Receivable, to our Consolidated Financial Statements. Product Warranty Accrual Our product warranty accrual decreased to $1,305,000 at December 31, 2006 from $1,835,000 at June 30, 2006, due to a $750,000 reduction in December 2006 in the warranty related to our Rare Earth Ovonic joint venture. See Note E, Liabilities, to our Consolidated Financial Statements. We generally provide a 20-year product warranty on power output on all Uni-Solar products installed as part of pre-engineered solutions. Government Contracts, Reserves and Liabilities Our reserves and liabilities for government contracts was relatively unchanged ($2,421,000 at December 31, 2006 from $2,345,000 at June 30, 2006). See Note E, Liabilities, to our Consolidated Financial Statements. Forward-Looking Statements This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, including in particular statements about our financial condition, results of operations, plans, objectives, expectations, future performance and business prospects. These statements are identified by forward-looking words such as may, will, anticipate, believe, estimate, expect, intend, plan, seek and similar expressions. We have based these forward-looking statements on our current expectations with respect to future events and occurrences, but our actual results in the future may differ materially from the expected results reflected in our forward-looking statements. Important factors that could cause our actual results to differ materially from the
results anticipated by the forward-looking statements include general economic and industry conditions in the markets in which we operate, risks associated with conducting business in foreign countries, and the risks discussed in Item 1A, Risk Factors, of our Annual Report on Form 10-K for the fiscal year ended June 30, 2006, and in other filings with the SEC from time to time. Any or all of these factors could cause our actual results and financial or legal status for future periods to differ materially from those expressed or referred to in any forward-looking statement. All written or oral forward-looking statements attributable to us are expressly qualified in their entirety by these cautionary statements. Forward-looking statements speak only as of the date on which they are made. Except as required by law, we undertake no obligation to update, amend or clarify forward-looking statements, whether as a result of new information, future events or otherwise.   47     Table of Contents  Item 3.
Quantitative and Qualitative Disclosures about Market Risk
 The following discussion about our exposure to market risk of financial instruments contains forward-looking statements. Actual results may differ materially from those described. Our holdings of financial instruments are comprised of debt securities and time deposits. All such instruments are classified as securities available-for-sale. We do not invest in portfolio equity securities, or commodities, or use financial derivatives for trading purposes. Our debt security portfolio represents funds held temporarily, pending use in our business and operations. The Company had $351,290,000 and $403,816,000 of these investments (including cash equivalents) on December 31, 2006 and June 30, 2006, respectively. It is the Companys policy that investments (including cash equivalents) shall be rated A or higher by Moodys or Standard and Poors, no single investment (excluding cash equivalents) shall represent more than 10% of the portfolio and at least 10% of the total portfolio shall have maturities of 90 days or less. Our market risk primarily relates to the
risks of changes in the credit quality of issuers. An interest rate change of 1% would result in a change in the value of our December 31, 2006, portfolio of approximately $353,000. Item 4.
Controls and Procedures
 As of December 31, 2006, the end of the period covered by this report on Form 10-Q, an evaluation was carried out under the supervision and with the participation of ECDs management, including our Chief Executive Officer and Chief Financial Officer, of our disclosure controls and procedures. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the design and operation of these disclosure controls and procedures were effective to ensure that we are able to collect, process and disclose the information we are required to disclose in the reports we file with the SEC within the required time periods. There has been no change in our internal control over financial reporting that occurred during our most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.    48     Table of Contents  PART II  OTHER INFORMATION  Item 1A.
Risk Factors
 There have been no material changes from the risk factors as previously disclosed in Item 1A, Risk Factors, of our Annual Report on Form 10-K for the fiscal year ended June 30, 2006. Item 4.
