American Superconductor Corporation (the Company or AMSC) was founded on April 9, 1987. The Company is an energy technologies company, offering an array of solutions based on two proprietary technologies: programmable power electronic converters and high temperature superconductor (HTS) wires. The Company’s products, services and system-level solutions enable cleaner, more efficient and more reliable generation, delivery and use of electric power. The programmability and scalability of the Company’s power electronic converters differentiate them from most competitive offerings. The two primary markets the Company serves are the wind energy market and the power transmission and distribution – or “power grid”—market. The Company operates in two business segments—AMSC Power Systems and AMSC Superconductors.

These unaudited condensed consolidated financial statements of the Company have been prepared in accordance with the Securities and Exchange Commission’s (SEC) instructions to Form 10-Q. Certain information and footnote disclosures normally included in the financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to those instructions. The year-end condensed balance sheet data was derived from audited financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America. The unaudited condensed consolidated financial statements, in the opinion of management, reflect all adjustments (consisting of normal recurring adjustments) necessary for a fair statement of the results for the interim periods ended September 30, 2007 and 2006 and the financial position at September 30, 2007. The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany balances and transactions are eliminated in consolidation.

The results of operations for the interim periods are not necessarily indicative of the results of operations to be expected for the fiscal year. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements for the fiscal year ended March 31, 2007 which are contained in the Company’s Annual Report on Form 10-K filed with the SEC on June 14, 2007.

The Company accounts for its stock-based compensation under the fair value recognition provisions of Statement of Financial Accounting Standards (SFAS) No. 123(R), “Share-Based Payments.” The following table summarizes stock-based compensation expense under SFAS 123(R) by financial statement line item for the three and six months ended September 30, 2007 and 2006 (in thousands):

The total unrecognized compensation cost for unvested stock-based compensation awards outstanding, net of forfeitures, was $7.9 million at September 30, 2007. This expense will be recognized over a weighted-average expense period of 1.7 years.

The assumptions used in the Black-Scholes valuation model for stock options granted during the three and six months ended September 30, 2007 and 2006 are as follows:

The expected volatility rate was estimated based on an equal weighting of the historical volatility of the Company’s common stock and the implied volatility of the Company’s traded options. The expected term was estimated based on an analysis of the Company’s historical experience of exercise, cancellation, and expiration patterns. The risk-free interest rate is based on five-year U.S. Treasury rates. The Company has applied an annual forfeiture rate of 13.79% as of September 30, 2007. This analysis is re-evaluated periodically and the forfeiture rate is adjusted as necessary.

On August 3, 2007, the Company’s stockholders approved two new stock plans: the 2007 Stock Incentive Plan (3,000,000 shares) and the 2007 Director Stock Plan (300,000 shares).

Basic earnings per share (EPS) is computed by dividing net earnings (loss) by the weighted-average number of common shares outstanding for the period. Diluted EPS is computed by dividing the net earnings (loss) available to common stockholders by the weighted average number of common shares and dilutive common equivalent shares outstanding during the period, calculated using the treasury stock method. Common equivalent shares include the effect of restricted stock and the exercise of stock options and warrants. For the three and six months ended September 30, 2007 and 2006, common equivalent shares of 4.6 million were not included in the calculation of diluted EPS as they were considered anti-dilutive.

The following table reconciles the numerators and denominators of the earnings per share calculation for the three and six months ended September 30, 2007 and 2006 (in thousands, except per share data):

The components of inventory are as follows (in thousands):

Finished goods inventory includes the cost of products shipped to customers on contracts for which revenue is deferred until final customer acceptance.

Deferred program costs of $0.6 million as of September 30, 2007 represent costs incurred in the Department of Homeland Security (DHS) HYDRA project after the expiration of the first 90 day letter contract the Company had in place with DHS. These program costs were inventoried because the Company deems probable that these costs incurred related to the project will be recoverable under the final contract terms and conditions that are subject to on-going negotiations with DHS. On November 1, 2007, the Company entered into a second 90 day contract with DHS, covering the period from the expiration of the first 90 day contract through November 16, 2007. As a result, these inventoried costs will be relieved from inventory and the related revenue will be recognized in the third quarter of fiscal 2007.

Deferred program costs of $1.2 million as of March 31, 2007 primarily represent $1.1 million of costs incurred in excess of funding on a Department of Energy (DOE) sponsored program to install an HTS power cable in the transmission grid of the Long Island Power Authority (LIPA). These program costs were inventoried because future funding sufficient to recover these deferred costs was deemed probable. In May 2007, DOE awarded the Company a contract modification of $4.0 million to cover additional subcontractor costs on the LIPA project which increased the contract ceiling to $27.5 million and the deferred program costs were expensed.

During the quarter ended June 30, 2007, the Company wrote off $0.9 million of finished goods related to the SuperVAR synchronous condenser the Company had planned to ship to a customer during the year. This write-off was due to management’s decision to cease investing in this technology and the customer’s agreement to terminate the contract. The write-off was included in Costs of Revenue for the AMSC Superconductors business unit.

The Company recorded income tax expense of $0.5 million and $0.8 million for the three and six months ended September 30, 2007 related primarily to foreign taxes. The Company has provided a valuation allowance against all current or deferred income tax assets because of the net operating losses incurred by the Company since its inception.

The Company adopted the provisions of FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes—an interpretation of FASB Statement No. 109” (FIN 48) on April 1, 2007. FIN 48 prescribes the recognition and measurement of a tax position taken or expected to be taken in a tax return. It also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and

(Unaudited)

transition. The Company performed a comprehensive review of its tax positions in accordance with recognition standards established by FIN 48. In this regard, an uncertain tax position represents the Company’s expected treatment of a tax position taken in a filed tax return, or planned to be taken in a future tax return, that has not been reflected in measuring income tax expense for financial reporting purposes. As a result of this review, the Company does not believe that it has included any “uncertain tax positions” in its federal tax return or any of the state or foreign income tax returns it is currently filing or has filed. At the adoption date of April 1, 2007 and September 30, 2007, the Company had no unrecognized tax benefits. The Company recognizes interest and penalties related to uncertain tax positions in income tax expense. As of the adoption date of April 1, 2007 and September 30, 2007, the Company had no accrued interest related to uncertain tax positions. The Company files federal, state and foreign income tax returns. Major tax jurisdictions include the U.S. and Austria. All years from 1991 to the current year remain open and subject to examination in the United States and all years from 2002 to the current year remain open and subject to examination in Austria.

In April 2005, the Company issued to TM Capital (which subsequently assigned it to Provident Premier Master Fund, Ltd.) a common stock purchase warrant for 0.2 million shares of the Company’s common stock, exercisable for a five-year term, with an exercise price of $9.50 per share (the “Warrant”). The accrued warrant cost will continue to be classified as a current liability in accordance with Emerging Issues Task Force (EITF) Issue No. 00-19, “Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company’s Own Stock”, until such time as the Warrant is exercised or forfeited, and will be marked-to-market based primarily on the current price and expected volatility of the Company’s common stock as of the end of each reporting period. The Warrant was re-valued at $2.6 million as of September 30, 2007, resulting in a loss of $0.3 million and $1.3 million for the three and six months ended September 30, 2007, respectively (reported in Other income (expense) in the Unaudited Condensed Consolidated Statements of Operations). The following Black-Scholes assumptions were used:

In September 2001, the Company entered into a standby letter of credit arrangement with a financial institution to provide a guarantee for rent of $1.0 million for the Two Technology Drive facility in Westborough, Massachusetts. The letter of credit amount was reduced to $0.8 million at June 1, 2005 and was reduced to $0.5 million at June 1, 2007. This letter of credit will expire on July 31, 2009.

As of March 31, 2007, the Company had an outstanding performance bond in the form of a bank guarantee for €0.1 million (approximately $0.1 million) issued on behalf of the Company’s Windtec subsidiary in connection with a contract to provide power electronics for a Chinese customer. This performance bond expired on June 30, 2007. A new performance bond was issued for €0.9 million (approximately $1.2 million) on April 25, 2007. This performance bond expires in December 2007. During the three months ended September 30, 2007, the Company entered into two new performance bonds with the same customer for a total of €0.2 million (approximately $0.2 million). In the event that the payment is made in accordance with the requirements of these performance bonds, the Company would record the payment as an offset to revenue. To secure the performance bonds, the Company has €0.75 million (approximately $1.1 million) in restricted cash classified as Prepaid expenses and other current assets.

(Unaudited)

In the quarter ended September 30, 2007, the Company entered into several long-term construction contracts with electric utilities which required the Company to obtain performance bonds. The Company is required to deposit an amount equivalent to some or all of the face amount of the performance bonds into an escrow account until the termination of the bond. Cash deposited in this account is classified as Prepaid expenses and other current assets or as Other assets on the Condensed Consolidated Balance Sheet depending on the time period the cash is required to be held as collateral. At September 30, 2007, approximately $7.9 million in performance bonds were outstanding. Collateralizing these performance bonds was $1.1 million of restricted cash, recorded in Prepaid expenses and other current assets and $3.2 million of restricted cash, recorded in Other assets.

The Company also has an unused line of credit of €0.6 million (or approximately $0.8 million) which is available until June 30, 2010. This line of credit is secured with accounts receivable.

Product Warranty

The Company generally provides a one-year warranty on its power electronic converters, commencing upon installation. A provision is recorded upon revenue recognition to Costs of revenue for estimated warranty expense based on historical experience.

Product warranty activity was as follows (in thousands):

The Company has entered into several cost-sharing arrangements with various agencies of the United States government. Funds paid to the Company under these agreements are not reported as revenues but are used to directly offset the Company’s research and development (“R&D”) and selling, general and administrative (“SG&A”) expenses, and to purchase capital equipment. The Company incurred R&D and SG&A costs offset by funding received under these agreements of $1.5 million and $0.6 million, respectively, for the three months ended September 30, 2007, and $1.9 million and $0.8 million, respectively, for the three months ended September 30, 2006. The Company incurred R&D and SG&A costs offset by funding received under these agreements of $2.9 million and $1.2 million, respectively, for the six months ended September 30, 2007, and $3.6 million and $1.5 million, respectively, for the six months ended September 30, 2006. At September 30, 2007, total funding received to date under these agreements was $24.4 million.

Acquisition of Power Quality Systems, Inc.

On April 27, 2007, the Company acquired Power Quality Systems, Inc. (PQS) for $4.5 million as described below. Located in Pennsylvania, PQS offers reactive compensation products known as Static VAR Compensators, or “SVCs”, based on its proprietary thyristor switch technology. These products enhance the reliability of power transmission and distribution grids and improve the quality of power for manufacturing

operations. PQS is being integrated into the AMSC Power Systems business unit. The acquisition has been accounted for under the purchase method of accounting in accordance with SFAS No. 141, “Business Combinations”, (SFAS No. 141). The Company allocated the purchase price to the assets acquired and liabilities assumed at their estimated fair values as of the date of acquisition. The excess of the purchase price of $2.8 million paid by the Company over the estimated fair value of net assets acquired has been recorded as goodwill. Goodwill represents the value associated with the acquired workforce and synergies related to the merger of the two companies. The Company estimated the fair value of the intangible assets at $2.3 million, which consists of contractual relationships and backlog of $0.1 million, customer relationships of $0.6 million and core-technology and know-how of $1.6 million.

Pursuant to the Merger Agreement, the Company acquired all of the issued and outstanding shares of PQS, for which the Company issued 295,329 shares of the Company’s common stock. The Company valued the acquisition at $4.3 million (excluding acquisition costs) using a value of $14.73 per share, which represents the five-day average closing price of the common stock from the two trading days before through two trading days after the signing of the Merger Agreement and the public announcement of the acquisition. The shares are subject to a lockup agreement whereby the former owners of PQS may sell only a certain number of shares per year through April 2009. While the former owners of PQS have not been employed by the Company subsequent to the acquisition, all key PQS engineering personnel remain employed by the Company. The all-stock transaction also includes an earn-out opportunity with the potential for up to an additional 0.5 million shares of Company common stock to be issued to PQS’s former owners based on the achievement of certain order growth targets for existing PQS products for the fiscal years ending March 2008 and 2009. This potential contingent consideration, if and when earned, will be recorded as additional goodwill based on the current fair value of the Company’s common stock at the time of issuance. As a result of this transaction, PQS is a wholly-owned subsidiary of the Company.

The results of PQS’s operations are included in the Company’s consolidated results from the date of acquisition of April 27, 2007. Assuming the acquisition of PQS had occurred on April 1, 2007 and 2006, the impact on the consolidated results of the Company would have been immaterial.

Unaudited Pro Forma Operating Results for the Acquisition of Windtec Consulting GmbH

Restructuring

On March 26, 2007, the Company’s Board of Directors approved a restructuring plan (the “Plan”) to reduce future operating costs and to transition its high temperature superconductor products to the manufacturing stage by consolidating the Company’s AMSC Wires, SuperMachines and Power Electronic Systems business segments into two operating segments: AMSC Superconductors and AMSC Power Systems.

The Company’s aggregate restructuring charges associated with the Plan were $0.8 million. The restructuring charge was allocated to the AMSC Superconductors operating segment. Of this total, $0.5 million of the restructuring charges were incurred during the quarter ended March 31, 2007 and $0.3 million were incurred during the six months ended September 30, 2007. As of September 30, 2007, the plan was substantially completed and the balance of the remaining liability was immaterial to the condensed consolidated financial statements.

Impairments

As of March 31, 2007, the Company reclassified its previously impaired first generation wire manufacturing equipment from “Property, Plant and Equipment” to “Assets held for sale”. The estimated salvage value of these assets was $2.2 million as of March 31, 2007. A public auction for the sale of these assets was held in June 2007 and the Company is currently negotiating private sales to interested parties for the remaining equipment. Based on the results of the auction and its work to sell through private sales, the Company had determined that an additional impairment charge of $0.6 million was required during the quarter ended June 30, 2007 to write down the value to its net realizable value. Assets held for sale at September 30, 2007 was $0.9 million, of which $0.7 million had been purchased but not yet shipped to the buyers.

The Company reports its financial results in two reportable business segments; AMSC Superconductors and AMSC Power Systems.

AMSC Power Systems supplies power electronic systems used in wind turbines; produces products to increase electrical grid capacity and reliability and to regulate wind farm voltage for the electrical grid; and, through its Windtec subsidiary, licenses proprietary wind energy system designs to manufacturers of such systems and provides consulting services to the wind industry.

AMSC Superconductors focuses on the manufacturing of HTS wire and coils; the design and development of HTS products, such as power cables, fault current limiters and motors; and the management of large-scale HTS projects, such as HTS power cable system design, manufacturing and installation.

The operating results for the two business segments are as follows (in thousands):

Total assets for the two business segments are as follows (in thousands):

The accounting policies of the business segments are the same as those for the consolidated Company, except that certain corporate expenses which the Company does not believe are specifically attributed or allocable to any of the two business segments have been excluded from the segment operating income (loss). Corporate unallocated expenses include stock-based compensation expense of $1.9 million and $1.0 million for the three months ended September 30, 2007 and 2006, respectively, and $3.0 million and $1.8 million for the six months ended September 30, 2007 and 2006, respectively. Corporate unallocated expenses also include the rent and occupancy costs associated with the unoccupied portion of the Company’s Westborough, Massachusetts, corporate headquarters.

In February 2007, the FASB Issued SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities-including an amendment of FASB Statement No. 115.” This standard permits entities to choose to measure many financial instruments and certain other items at fair value and provides the opportunity to mitigate volatility in reported earnings caused by measuring related assets and liabilities differently without having to apply complex hedge accounting provisions. This standard is effective for fiscal years beginning after November 15, 2007. The Company is currently evaluating the provisions of SFAS No. 159.

In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements”. SFAS No. 157 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles and expands disclosures about fair value measurements. SFAS No. 157 applies under other accounting pronouncements that require or permit fair value measurements, the FASB having previously concluded in those accounting pronouncements that fair value is the relevant measurement attribute. Accordingly, SFAS No. 157 does not require any new fair value measurements. SFAS No. 157 is effective for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years, with earlier adoption permitted. The provisions of SFAS No. 157 should be applied prospectively as of the beginning of the fiscal year in which it is initially applied, with limited exceptions. The Company is currently evaluating the provisions of SFAS No. 157.

On July 25, 2007, the Company completed a public offering of 4.7 million shares of its common stock at $21.25 per share. Net proceeds from the offering (after deducting underwriting discounts and commissions, but before deducting offering expenses) were $94.3 million.

On October 25, 2007, the Board of Directors approved a plan, which the Company announced it was considering earlier in the year, to consolidate its operations in Massachusetts. All personnel remaining at the Company’s headquarters in Westborough, Massachusetts will be re-located to its facility in Devens, Massachusetts and the Westborough facility will be closed. The consolidation is expected to result in total restructuring charges for lease termination, relocation, and other costs in the range of $5.5 million to $6.0 million, of which $4.5 million to $5.0 million is expected to be recorded in the last two quarters of the fiscal year ending March 31, 2008, with the majority of these costs expected to be incurred in the third quarter, when the relocation is expected to be substantially completed. The remaining amount is expected to be incurred ratably over the remaining term of the lease on the vacated facility, which expires in May 2009. Of the total restructuring charge, approximately $4.0 to $4.5 million relates to costs associated with terminating the lease, with the remainder for relocation of equipment and employees. All of the restructuring charges will involve cash expenditures.

AMERICAN SUPERCONDUCTOR CORPORATION

Executive Overview

American Superconductor Corporation was founded in 1987. We are a leading energy technologies company, offering an array of solutions based on two proprietary technologies: programmable power electronic converters and high temperature superconductor (HTS) wires. Our products, services and system-level solutions enable cleaner, more efficient and more reliable generation, delivery and use of electric power. The programmability and scalability of our power electronic converters differentiate them from most competitive offerings. Our HTS wires carry 150 times the electrical current of comparably sized copper wire. The two primary markets we serve are the wind energy market and the power transmission and distribution—or “power grid”—market.

Our HTS wire addresses constraints on the power grid by increasing the electric current carrying capacity of the transmission cables comprising these power grids and by providing current limiting functionality in cables and standalone devices. In addition, our HTS wire, when incorporated into primary electrical equipment such as motors and generators, can provide increased manufacturing and operating savings due to a significant reduction in the size and weight of this equipment. Also, our power electronic converters increase the quantity, quality and reliability of electric power that is transmitted by electric utilities or consumed by large industrial entities.

Our products are in varying stages of commercialization. Our power electronic converters have been sold commercially, as part of integrated systems, to utilities, manufacturers and wind farm developers, owners and operators since 1999. We began production of our first generation, or “1G” HTS wire in 2003, although its principal applications (power cables, fault current limiters, rotating machines and specialty magnets) are currently in the prototype stage. Some of these prototypes are funded by U.S. government contracts, primarily with the Department of Defense (DOD) and Department of Energy (DOE).

We are currently in the process of converting our pre-pilot production line for 344 superconductors, our brand name for what is generically known as second generation or “2G” HTS wire, into a full-scale manufacturing line, which we expect will have an initial gross production capacity of approximately 720,000 meters of 344 superconductors per year in December 2007.

On July 25, 2007, we completed a public offering of 4.7 million shares of our common stock at $21.25 per share. Net proceeds from the offering (after deducting underwriting discounts and commissions, but before deducting offering expenses) were $94.3 million.

Our cash requirements depend on numerous factors, including successful completion of our product development activities, ability to commercialize our product prototypes, rate of customer and market adoption of our products and the continued availability of U.S. government funding during the product development phase. Significant deviations to our business plan with regard to these factors, which are important drivers to our business, could have a material adverse effect on our operating performance, financial condition, and future business prospects. We expect to pursue the expansion of our operations through internal growth and potential strategic alliances and acquisitions. As of September 30, 2007, we have spent approximately $11.9 million related to our HTS wire manufacturing facility in Devens, Massachusetts. We expect to spend an additional $3.2 million during the fiscal year ending March 31, 2008 on this project.

On January 5, 2007, we completed the acquisition of Windtec Consulting GmbH (Windtec). Windtec is an Austria-based designer and licensor of wind energy systems. Windtec is now a wholly-owned subsidiary and is operated by our AMSC Power Systems business unit. The Windtec purchase price was 1.3 million shares of our common stock, valued at approximately $13.1 million based on a five-day average stock price of $10.08 per

share at the time of signing the definitive acquisition agreements and public announcement of the acquisition on November 28, 2006. The shares are subject to a lockup whereby the former sole owner and founder of Windtec may sell only a certain number of shares per year through January 2010. The all-stock transaction also includes an earn-out opportunity with the potential for the issuance of up to an additional 1.4 million shares of our common stock to be granted to the former owner and founder based on the achievement by Windtec of certain revenue growth targets for the years ending March 31, 2008 through March 31, 2011. Beginning on January 5, 2007, Windtec’s results of operations are included in our consolidated financial statements.

On April 27, 2007, we acquired Power Quality Systems, Inc. (PQS), a Pennsylvania corporation. Pursuant to the Merger Agreement, we acquired all of the issued and outstanding shares of PQS, for which we issued 295,329 shares of our common stock. We valued the acquisition at approximately $4.3 million (excluding acquisition costs) using a value of $14.73 per share, which represents the five-day average closing price of the common stock from the two trading days before through two trading days after the signing of the Merger Agreement and the public announcement of the acquisition. The shares are subject to a lockup agreement whereby the former owners of PQS may sell only a certain number of shares per year through April 2009. While the former owners have not been employed by us subsequent to the acquisition, all key PQS engineering personnel are employed by us. The all-stock transaction also includes an earn-out opportunity with the potential for up to an additional 475,000 shares of our common stock to be issued to PQS’s former owners based on the achievement of certain order growth targets for existing PQS products for the fiscal years ending March 2008 and 2009. This potential contingent consideration, if and when earned, will be recorded as additional goodwill based on the fair value of our common stock at the time of issuance. As a result of this transaction, PQS is a wholly-owned subsidiary and is operated by AMSC Power Systems.

The results of PQS’s operations are included in our consolidated results from the date of acquisition of April 27, 2007.

Critical Accounting Policies and Estimates

The preparation of consolidated financial statements requires that we make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. We base our estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ under different assumptions or conditions.

Our accounting policies that involve the most significant judgments and estimates are as follows:

Revenue.    For certain arrangements, such as prototype development contracts and certain product sales, we record revenues using the percentage-of-completion method, measured by the relationship of costs incurred to total estimated contract costs. We use the percentage-of-completion revenue recognition method when a purchase arrangement meets all of the criteria in Statement of Position 81-1. Percentage-of-completion revenue recognition accounting is predominantly used on certain turnkey power systems installations for electric utilities and long-term prototype development contracts with the U.S. government, such as the 36.5 MW motor contract

with the U.S. Navy. We follow this method since reasonably dependable estimates of the revenues and costs applicable to various stages of a contract can be made. However, the ability to reliably estimate total costs at completion is challenging, especially on long-term prototype development contracts, and could result in future changes in contract estimates. Since many contracts extend over a long period of time, revisions in scope and cost and funding estimates during the progress of work have the effect of adjusting earnings applicable to prior-period performance in the current period. Recognition of contract revenues and profit or loss are subject to revisions as the contract work progresses to completion. Revisions in profit or loss estimates are charged to income in the period in which the facts that give rise to the revision become known. During the six months ended September 30, 2007, we recorded an additional $0.2 million related to subcontractor claims to close-out subcontracts related to the Navy 36.5MW motor in addition to the $3.1 million loss recorded in the prior year ended March 31, 2007, as a result of cost overruns and changes in estimates. As of September 30, 2007, we recorded a loss of $3.3 million related to the Navy 36.5 MW motor program. The motor was delivered to the Navy in June 2007.

We recognize revenue for other product sales upon customer acceptance, which can occur at the time of delivery, installation, or post-installation, where applicable, provided persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable and the collectibility is reasonably assured. For multiple-element arrangements, we use the residual method to allocate value to the delivered item. Under the residual method, each undelivered item is allocated value based on verifiable objective evidence of fair value for that item and the remainder of the total arrangement price is allocated to the delivered items. For a delivered item to be considered a separate unit of accounting, the delivered item must have value to the customer on a standalone basis, there must be objective and reliable evidence of fair value of the undelivered items in the arrangement and the delivery or performance of the undelivered items must be considered probable and substantially within our control. We do not provide our customers with contractual rights of return for any of our products. When other significant obligations remain after products are delivered, revenue is recognized only after such obligations are fulfilled. The determination of what constitutes a significant post-delivery performance obligation (if any post-delivery performance obligations exist) is the primary subjective consideration we systemically evaluate in the context of each product shipment in order to determine whether to recognize revenue on the order or to defer the revenue until all post-delivery performance obligations have been completed.

We occasionally enter into construction contracts that include a performance bond. As these contracts progress, we continually assess the probability of a payout from the performance bond. Should we determine that such a payout is likely, we would record a liability. Under the guidance of EITF 01-09: “Accounting for Consideration Given to a Customer or a Retailer of the Vendor’s Products” we may be required to reduce previously recognized revenue should a liability be recorded. As of September 30, 2007 we have not recorded a liability with respect to performance bonds.

Revenues associated with consulting, training and other similar services are recognized as the services are performed. Royalty revenue is recognized as the royalties are earned.

Deferred revenue and customer deposits include customer advances and amounts that have been billed or contracts that permit billings to occur in advance of contract performance.

Long-Lived Assets.    We periodically evaluate our long-lived assets consisting principally of fixed assets and intangible assets for potential impairment under Statement of Financial Accounting Standards (SFAS) No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets.” We perform these evaluations whenever events or circumstances suggest that the carrying amount of an asset or group of assets is not recoverable. Our judgments regarding the existence of impairment indicators are based on market and operational performance. Indicators of potential impairment include:

16

Table of Contents

If we believe an indicator of potential impairment exists, we test to determine whether impairment recognition criteria in SFAS No. 144 have been met. To analyze a potential impairment, we project undiscounted future cash flows expected to result from the use and eventual disposition of the asset or primary asset in the asset group over its remaining useful life. If these projected cash flows are less than the carrying amount, an impairment loss is recognized in the Consolidated Statements of Operations based on the difference between the carrying value of the asset or asset group and its fair value, less any disposition costs. Evaluating the impairment requires judgment by our management to estimate future operating results and cash flows. If different estimates were used, the amount and timing of asset impairments could be affected.

Inventory.    We write down inventory for estimated obsolescence or unmarketable inventory in an amount equal to the difference between the cost of the inventory and the estimated realizable value based upon assumptions of future demand and market conditions. If actual market conditions are less favorable than those projected, additional inventory write-downs may be required. Program costs may be deferred and recorded as inventory on contracts on which costs are incurred in excess of approved contractual amounts and/or funding, if future recovery of the costs is deemed probable.

Income taxes.    In accordance with applicable accounting standards, we regularly assess our ability to realize our deferred tax assets. Assessments of the realization of deferred tax assets require that management consider all available evidence, both positive and negative, make significant judgments about many factors, including the amount and likelihood of future taxable income. Based on all the available evidence, we have recorded a valuation allowance to reduce our U.S. deferred tax assets to the amount that is more likely than not to be realizable due to the taxable losses incurred by us since our inception. Under current federal law, the utilization of the net operating loss and research and development and other tax credit carryforwards may be subject to limitations due to changes in ownership.

We adopted the provisions of FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes—an interpretation of FASB Statement No. 109” (FIN 48) on April 1, 2007. FIN 48 prescribes the recognition and measurement of a tax position taken or expected to be taken in a tax return. It also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. We performed a comprehensive review of our tax positions in accordance with recognition standards established by FIN 48. In this regard, an uncertain tax position represents the company’s expected treatment of a tax position taken in a filed tax return, or planned to be taken in a future tax return, that has not been reflected in measuring income tax expense for financial reporting purposes. As a result of this review, we do not believe that it has included any “uncertain tax positions” in our federal tax return or any of the state or foreign income tax returns we are currently filing or have filed. At the adoption date of April 1, 2007 and September 30, 2007, we had no unrecognized tax benefits. We recognize interest and penalties related to uncertain tax positions in income tax expense. As of the adoption date of April 1, 2007 and September 30, 2007, we had no accrued interest related to uncertain tax positions. We file federal, state and foreign income tax returns. Major tax jurisdictions include the U.S. and Austria. All years from 1991 to the current year remain open and subject to examination in the United States and all years from 2002 to the current year remain open and subject to examination in Austria.

Goodwill.    Goodwill represents the excess of cost over net assets of acquired businesses that are consolidated. In accordance with SFAS No. 142, “Goodwill and Other Intangible Assets,” goodwill is not amortized. In lieu of amortization, we perform an impairment review of our goodwill at least annually in our fourth quarter or when events and changes in circumstances indicate the need for such a detailed impairment analysis. Goodwill is considered impaired when the carrying value of a reporting unit exceeds its estimated fair

17

Table of Contents

value. In assessing the recoverability of goodwill, we make assumptions regarding estimated future cash flows and other factors to determine the fair value of the reporting unit. To date, we have determined that goodwill is not impaired, but we could in the future determine that goodwill is impaired, which would result in a charge to earnings.

Acquisition accounting.    We account for acquisitions under the purchase method of accounting in accordance with SFAS No. 141, “Business Combinations”. We allocate the purchase price to the assets acquired and liabilities assumed based on their estimated fair values as of the date of acquisition. The excess of the purchase price paid by us over the estimated fair value of identifiable net assets acquired is recorded as goodwill.

Results of Operations

On March 26, 2007, in connection with the Board of Directors’ approval of the restructuring plan, we began operating and reporting our financial results to the Chief Executive Officer in two reportable business segments: AMSC Superconductors and AMSC Power Systems. Accordingly, we recast our prior year business segment financial information to conform to the new segment presentation.

AMSC Power Systems supplies power electronic systems used in wind turbines; produces products to increase electrical grid capacity and reliability and to regulate wind farm voltage for the electrical grid; and, through our Windtec subsidiary, licenses proprietary wind energy system designs to manufacturers of such systems and provides consulting services to the wind industry.

During the fourth quarter of the year ended March 31, 2007, we acquired Windtec and integrated the business into our AMSC Power Systems business unit. Results of Windtec’s operations are included in our consolidated results from the date of acquisition on January 5, 2007.

During the first fiscal quarter ended June 30, 2007, we acquired PQS and integrated the business into our AMSC Power Systems business unit. Results of PQS’s operations are included in our consolidated results from the date of acquisition on April 27, 2007.

AMSC Superconductors focuses on the manufacturing of HTS wire and coils; the design and development of HTS products, such as power cables, fault current limiters and motors; and the management of large-scale HTS projects, such as HTS power cable system design, manufacturing and installation.

Revenues

Total revenues increased by 125% and 75% to $21.6 million and $41.4 million in the three and six months ended September 30, 2007, respectively, from $9.6 million and $23.6 million for the same periods of the prior year, representing increases of $12.0 million and $17.8 million, respectively. Our revenues are summarized as follows (in thousands):

Revenues in our AMSC Power Systems unit consist of revenues from D-VAR, PQ-IVR, PQ-SVC, SVC, and PowerModule product sales, service contracts, consulting arrangements and wind energy system prototype development contracts. Revenues in the Power Systems unit increased 196% and 235%, to $19.2 million and

18

Table of Contents

$33.6 million in the three and six months ended September 30, 2007, respectively, from $6.5 million and $10.0 million in the same periods of the prior year, respectively. The increases were driven primarily by the effect of our acquisitions of Windtec and PQS, which contributed $10.8 million and $18.6 million to revenues in the three and six months ended September 30, 2007, respectively. The remainder of the increase was primarily due to higher sales of our PowerModules to support wind technology applications.

Revenues in our AMSC Superconductors business unit consist of contract revenues, HTS wire sales, revenues under the DOE-sponsored project to install an HTS power cable in the transmission grid of LIPA, revenues under a Department of Homeland Security (DHS) sponsored project, named Project HYDRA, to install our Secure Super Grids^™ solution in the Manhattan power grid, and prototype development contracts. AMSC Superconductors revenue declined 22% and 42% to $2.4 million and $7.8 million in the three and six months ended September 30, 2007, respectively, from $3.1 million and $13.6 million in the same periods of the prior year, respectively. The decreases were driven primarily by lower revenues from the 36.5 MW motor program for the U.S. Navy as work has been substantially completed on this program. We also experienced a decrease in 1G wire sales, as this product-line has been discontinued. These decreases were partially offset by higher LIPA project revenues and revenues from Project HYDRA in the three and six months ended September 30, 2007.

On April 26, 2006, a contract modification from the Navy on the 36.5 MW motor program was received that provided $13.3 million in additional funding, thereby increasing the contract value to $90.2 million and converting it from a cost-plus-incentive-fee contract to a firm-fixed-price contract. Revenues on this program are recognized on a percentage-of-completion basis and, as such, are subject to adjustments when estimates to complete the program are revised. The revenue decrease of $1.2 million from the prior-year quarter related to the 36.5 MW motor program is due to a lower level of work performed on the motor program in the quarter ended September 30, 2007. During July 2007, we completed this contract and recognized $0.1 million of revenue in the quarter ended September 30, 2007.

On October 13, 2006, we signed a cost-plus-fixed-fee contract valued at $5.3 million with the U.S. Naval Sea Systems Command (NAVSEA) for the design and optimization of HTS ship propulsion motors and power electronic drives. During the quarter ended September 30, 2007, the incremental funding allotted for the initial stage of this contract, which is expected to be completed in the next six months, increased to $2.6 million from $1.9 million. We recognized $0.6 million and $0.9 of revenue during the three and six months ended September 30, 2007, respectively, on this contract under the percentage-of-completion method. We are pursuing additional contracts for HTS motors and generators with the U.S. Navy and our strategic business alliance partner, Northrop Grumman Marine Systems, among others. However, we expect revenues related to motors to be significantly lower in the year ending March 31, 2008 compared to the year ended March 31, 2007 as we delivered the 36.5 MW motor in June 2007 and completed the final phase of the $90.2 million Navy contract.

LIPA project revenues were $0.3 million and $3.5 million for the three and six months ended September 30, 2007, respectively, as compared to $0.5 and $1.0 million for the same periods of the prior year, respectively. The decrease in revenues from the prior-year quarter is due to a decrease in the level of spending as the project nears completion. The increase for the six months ended September 30, 2007 was due to funding limitations that were in place during the same period of the prior year from the DOE. In May 2007, the DOE awarded a contract modification of $4.0 million to cover subcontractor cost growth on the LIPA project, increasing the contract ceiling to $27.5 million.

We anticipate that we will realize additional HTS cable project revenues in the year ending March 31, 2008 from the Project HYDRA contract with Consolidated Edison, Inc., which is being funded by the DHS and was announced on May 21, 2007. DHS is expected to invest up to a total of $25.0 million in the development of a new high temperature superconductor power grid technology to enable Secure Super Grids. Secure Super Grids utilize customized HTS wires, HTS power cables and ancillary controls to deliver more power through the grid while also being able to suppress power surges that can disrupt service. On May 18, 2007, we signed a letter contract valued at $1.7 million, of which DHS provided initial funding of $1.1 million, to commence work on this project. We recognized $0.4 million and $0.6 million in revenue related to the HYDRA project during the

19

Table of Contents

three months and six months ended September 30, 2007, respectively. On November 1, 2007, we entered into a second 90 day contract with DHS, covering the period from the expiration of the first 90 contract through November 16, 2007. We are continuing to negotiate the terms and conditions for this multi-party contract. Consolidated Edison and Southwire Company are expected to be subcontractors to us.

Wire sales to other customers decreased to $0.3 million and $0.6 million in the three and six months ended September 30, 2007, respectively, compared to $0.6 million and $1.1 million in the same periods of the prior year, respectively, as a result of lower 1G HTS wire demand as we transition to manufacturing 344 superconductors. We expect wire sales to other customers and contract revenues to decline in the year ending March 31, 2008. We are in the process of installing, testing, and qualifying capital equipment for manufacturing our 344 superconductors, the sales of which are currently constrained by limited manufacturing capacity. We expect to sell limited quantities of 344 superconductors wire while we expand our manufacturing line. We expect to have an annual gross capacity of 720,000 meters of wire at the end of calendar year 2007. We expect to continue to meet near-term customer demand for HTS wire from the approximately 250,000 meters of 1G HTS wire remaining in inventory, of which approximately 170,000 meters remained available for sale as of September 30, 2007.

Cost-sharing funding

In addition to reported revenues, we also received funding of $0.6 million and $1.2 million for the three months and six months ended September 30, 2007, respectively, under U.S. government cost-sharing agreements with the U.S. Air Force and DOE, compared to $0.8 million and $1.5 million for the same periods of the prior year, respectively. The decreases in cost-sharing funding are primarily due to the DOE Wire Initiative program nearing completion. All of our cost-sharing agreements provide funding in support of development work on 344 superconductors being done in the AMSC Superconductors business unit. We anticipate that a portion of our funding in the future will continue to come from cost-sharing agreements as we continue to develop joint programs with government agencies. Backlog as of September 30, 2007 relating to cost-sharing agreements was at $5.1 million. As required by government contract accounting guidelines, funding from government cost-sharing agreements is recorded as an offset to research and development and selling, general and administrative expenses, rather than as revenue.

Costs of Revenue

Costs of revenue increased by 75% and 40%, to $16.0 million and $32.2 million for the three and six months ended September 30, 2007, respectively, compared to $9.1 and $23.0 million for the same periods of the prior year, respectively. Gross margin was 26.0% and 22.2% for the three and six months ended September 30, 2007, respectively, compared to 3.0% and 2.5% for the same periods of the prior year, respectively. The increases in gross margin were due primarily to a higher mix of Power Systems sales as compared to Superconductors sales, which generally have zero or negative gross margins.

Operating Expenses

Research and development

A portion of our R&D expenditures related to externally funded development contracts has been classified as costs of revenue (rather than as R&D expenses). Additionally, a portion of R&D expenses was offset by cost-sharing funding. Our R&D expenditures are summarized as follows (in thousands):

20

Table of Contents

R&D expenses (exclusive of amounts classified as costs of revenue and amounts offset by cost-sharing funding) increased by 7% and 5% to $3.8 million and $8.0 million in the three and six months ended September 30, 2007, respectively, from $3.5 million and $7.6 million for the same periods of the prior year, respectively. The increases in R&D expenses were driven by the acquisition of PQS, higher stock-based compensation expenses and higher legal costs associated with patent activity. Aggregated R&D expenses, which include amounts classified as costs of revenues and amounts offset by cost-sharing funding increased 7% to $7.9 million for the three months ended September 30, 2007, compared to $7.4 million for the same period a year ago. The increase was driven by the same factors described above. Aggregated R&D expenses decreased 10% to $18.4 million for the six months ended September 30, 2007, compared to $20.4 million for the same period a year ago. The decrease was driven primarily by a lower level of externally funded program costs on the 36.5 MW motor program and a reduction in workforce as a result of the re-alignment of the AMSC Wires and SuperMachines business units in March 2007, partially offset by the added costs from the acquisitions of Windtec and PQS.

Selling, general, and administrative

A portion of the SG&A expenditures related to externally funded development contracts has been classified as costs of revenue (rather than as SG&A expenses). Additionally, a portion of SG&A expenses was offset by cost-sharing funding. Our SG&A expenditures are summarized as follows (in thousands):

SG&A expenses (exclusive of amounts classified as costs of revenue and amounts offset by cost-sharing funding) increased by 62% and 68% to $7.2 million and $13.3 million in the three and six months ended September 30, 2007, respectively, from $4.4 million and $7.9 million for the same periods of the prior year, respectively. The increases in SG&A expenses are due primarily to higher expenses associated with stock-based compensation, less absorption of SG&A costs into costs of revenue, and the inclusion of the incremental SG&A from Windtec and PQS in the current year. Aggregated SG&A expenses, which include amounts classified as costs of revenues and amounts offset by cost sharing funding increased 41% and 29% to $7.7 million and $14.4 million for the three and six months ended September 30, 2007, respectively, from $5.4 million and $11.2 million for the same periods of the prior year, respectively. The increases were due primarily to the incremental SG&A from the Windtec and PQS acquisitions, and increased stock compensation expense.

We present Aggregated R&D and Aggregated SG&A expenses, which are non-GAAP measures, because we believe this presentation provides useful information on our aggregate R&D and SG&A spending and because R&D and SG&A expenses as reported on the Consolidated Statements of Operations have been and may in the future be subject to significant fluctuations solely as a result of changes in the level of externally funded contract development work, resulting in significant changes in the amount of the costs recorded as costs of revenue rather than as R&D and SG&A expenses, as discussed above.

Amortization of Acquisition Related Intangibles

We recorded $1.8 million and $2.9 million in the three months and six months ended September 30, 2007, respectively, in amortization related to our contractual relationships/backlog, customer relationships, core technology and know-how, trade names and trademark intangible assets. There was no comparable amount in the prior year. These intangible assets are a result of our Windtec and PQS acquisitions.

Restructuring and impairments

On March 26, 2007, our Board of Directors approved a restructuring plan (the “Plan”) to reduce operating costs and to transition our high temperature superconductor products to the manufacturing stage by consolidating AMSC Wires, SuperMachines and Power Electronic Systems business segments into two operating segments: AMSC Superconductors and AMSC Power Systems. We consolidated our manufacturing operations by closing one of our two Westborough, Massachusetts facilities, moving operations from that facility into the Devens, Massachusetts plant, and reducing headcount by 37 employees.

Our aggregate restructuring charges associated with the Plan were $0.8 million. The restructuring charge was allocated to the AMSC Superconductors operating segment. Of this total, $0.5 million of the restructuring charges were incurred in the prior year and $0.3 million were incurred during the six months ended September 30, 2007. As of September 30, 2007, the plan was substantially completed and the balance of the remaining liability was immaterial to the condensed consolidated financial statements.

As of March 31, 2007, we reclassified our previously impaired first generation wire manufacturing equipment from “Property, Plant and Equipment” to “Assets held for sale”. The estimated salvage value of these assets was $2.2 million as of March 31, 2007. A public auction for the sale of these assets was held in June 2007 and we are currently negotiating private sales to interested parties for the remaining equipment. Based on the recent results of the auction and our work to sell through private sales, we determined that an additional impairment charge of $0.6 million was required during the quarter ended June 30, 2007 to write down the value to its net realizable value. Assets held for sale at September 30, 2007 was $0.9 million, of which $0.7 million had been purchased but not yet shipped to the buyers.

On October 25, 2007 we announced our intention to consolidate operations in Massachusetts. All personnel remaining at our headquarters in Westborough, Massachusetts will be re-located to our facility in Devens, Massachusetts and the Westborough facility will be closed. The consolidation is expected to result in total restructuring charges for lease termination, relocation, and other costs in the range of $5.5 million to $6.0 million, of which $4.5 million to $5.0 million is expected to be recorded in the last two quarters of the fiscal year ending March 31, 2008. The majority of these costs are expected to be incurred in the third quarter, when the relocation is expected to be substantially completed. The remaining amount is expected to be incurred ratably over the remaining term of the lease on the vacated facility, which expires in May 2009. Of the total restructuring charge, approximately $4.0 to $4.5 million relates to costs associated with terminating the lease, with the remainder for relocation of equipment and employees. All of the restructuring charges will involve cash expenditures. Excluding continuing restructuring charges related to the lease, we expect to realize annual savings of approximately $2.5 million per year as a result of this plan beginning in the fourth quarter of fiscal year ending March 31, 2008.

Operating income (loss)

Our operating income (loss) is summarized as follows (in thousands):

22

Table of Contents

The operating income at AMSC Power Systems increased by $0.6 million and $0.7 million to $0.8 million and $0.2 million in the three and six months ended September 30, 2007, respectively, from an operating income of $0.2 million and an operating loss of $0.5 million in the same periods of the prior year, respectively. The increases were the result of higher gross margins in the quarter ended September 30, 2007 in connection with the increased level of product sales. The increase in gross margin was partially offset by higher SG&A and R&D allocations to support the growth and integration required in AMSC Power Systems due to the recent acquisitions of Windtec and PQS. Amortization expense related to the Windtec and PQS acquisitions was $1.8 million and $2.9 million during the three and six months ended September 30, 2007, respectively.

The operating loss at AMSC Superconductors decreased by $0.7 million and increased by $0.3 million to $5.4 million and $11.9 million in the three and six months ended September 30, 2007, respectively, from an operating loss of $6.1 million and $11.6 million in the same periods of the prior year, respectively. The decrease in the second quarter was largely due to a loss on the 36.5 MW Navy contract of $1.0 million recorded in the second quarter of the prior year, offset by $0.2 million increase in SG&A expense allocations in the current period. The increase in the operating loss for the six months ended September 30, 2007 was primarily a result of a $0.9 million inventory write-off for a SuperVAR synchronous condenser, an asset impairment charge of $0.6 million related to the 1G assets held for sale, offset by a $0.2 million reduction in SG&A expense allocations and the $1.0 million loss in the prior year related to the 36.5 MW Navy contract described above.

Non-operating expenses/Interest income

Interest income increased to $1.2 million and $1.6 million for the three and six months ended September 30, 2007, respectively, from $0.6 million and $1.3 million for the same periods of the prior year, respectively. These increases in interest income reflect higher cash balances available for investment, largely the result of the $94.3 million in net proceeds we received in the stock offering completed on July 25, 2007.

Other income (expense), net, was $(0.2) million and $(1.2) million in the three and six months ended September 30, 2007, respectively, compared to $(0.1) million and $(0.1) million in the same periods of the prior year, respectively. These amounts consisted primarily of a loss on the revaluation of the stock warrant issued in April 2005 to TM Capital Corp., a past financial advisor to us, related to a litigation settlement. The accrued warrant cost will continue to be classified as a current liability in accordance with Emerging Issues Task Force (EITF) Issue No. 00-19 “Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company’s Own Stock” until such time as the warrant is exercised or forfeited, and will be marked to market based primarily on the current price and expected volatility of our common stock as of the end of each reporting period. The warrant was re-valued at $2.6 million as of September 30, 2007, resulting in a loss of $0.3 million and $1.3 million for the three months and six months ended September 30, 2007, respectively.

Income Taxes

During the three and six months ended September 30, 2007, we recorded income tax expense of $0.5 million and $0.8 million, respectively, primarily related to foreign taxes. Based on our latest operating plan, we expect to continue to incur operating losses through at least the end of the year ending March 31, 2009 as we continue to devote significant financial resources to our commercialization efforts for 344 superconductors and to our ongoing research and development activities.

Please refer to the “Risk Factors” section below for a discussion of certain factors that may affect our future results of operations and financial condition.

Liquidity and Capital Resources

At September 30, 2007, we had cash, cash equivalents and marketable securities of $118.2 million compared to $35.3 million at March 31, 2007, an increase of $82.9 million. Our cash, cash equivalents and marketable securities are summarized as follows (in thousands):

The increase in cash and cash equivalents to $87.1 million at September 30, 2007 from $15.9 million at March 31, 2007 was primarily the result of receiving $94.3 million in net proceeds from our July 2007 public offering (see below).

We have generated operating losses since our inception, and expect to continue incurring operating losses until at least until the end of the fiscal year ending March 31, 2009.

For the six months ended September 30, 2007, net cash used by operating activities was $11.5 million compared to a use of $15.5 million by operating activities in the same period a year ago. The improvement in cash used from operations is primarily due to lower net loss excluding non-cash items.

For the six months ended September 30, 2007, net cash used in investing activities was $19.5 million, compared to a use of $7.6 million in the same period a year ago. The increase was driven primarily by the net increase in cash invested in marketable securities.

As of September 30, 2007, we have invested in total approximately $11.9 million in the 344 superconductors production line, and we anticipate spending approximately an additional $3.2 million on this line in the fiscal year ending March 31, 2008. These expenditures are being made to enable us to achieve a gross production capacity of approximately 720,000 meters annually of 344 superconductors in December 2007 on our 4 cm manufacturing technology, and prepare to migrate to the our 10 cm manufacturing technology. We estimate that an additional $28.0 million to $35.0 million of capital expenditures would be needed for a full commercial manufacturing operation with a gross capacity of approximately 9 million meters of wire per year.

For the six months ended September 30, 2007, cash provided by financing activities was $102.0 million compared to $0.9 million in the same period a year ago. On July 25, 2007, we completed a public offering of 4.7 million shares of our common stock at $21.25 per share. Net proceeds from the offering (after deducting underwriting discounts and commissions, but before deducting offering expenses) were $94.3 million. An additional $8.2 million of proceeds from the exercise of stock options was also received during the period.

Although our cash requirements fluctuate based on a variety of factors, including customer adoption of our products and our research and development efforts to commercialize our products, we believe that our available cash will be sufficient to fund our working capital, capital expenditures, and other cash requirements for the next several years.

We also have an unused line of credit of €0.6 million (or approximately $0.8 million) which is available until June 30, 2010.

We had backlog at September 30, 2007 (excluding amounts included in accounts receivable) of approximately $180.3 million from government and commercial customers, compared to $75.1 million at June 30, 2007. Backlog represents the value of contracts and purchase orders received, less the revenue

recognized to date on those contracts and purchase orders. The sequential increase in backlog is due to $90.0 million of orders from our largest customer, Sinovel, for wind turbine electrical systems. The current backlog, including $18.3 million on U.S. government contracts, is subject to certain standard cancellation provisions. The current backlog includes approximately $12.1 million of backlog related to DOE awards for a 2G cable installation with LIPA and a fault current limiter project with Southern California Edison, and approximately $0.5 million of the letter contract with DHS, but does not include the remaining $24.0 million of the full contract that is currently being negotiated. Additionally, several of our government contracts are being funded incrementally, and as such, are subject to the future authorization and appropriation of government funding on an annual basis. We have a history of successful performance under incrementally-funded contracts with the government of the backlog amount of $180.3 million as of September 30, 2007, approximately 64% is billable to and potentially collectable from our customers within the next 12 months.

The possibility exists that we may pursue additional acquisition and joint venture opportunities in the future that may affect liquidity and capital resource requirements.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements, as defined under SEC rules, such as relationships with unconsolidated entities or financial partnerships, which are often referred to as structured finance or special purpose entities, established for the purpose of facilitating transactions that are not required to be reflected on our balance sheet except as discussed below.

We occasionally enter into construction contracts that include a performance bond. As these contracts progress, we continually assess the probability of a payout from the performance bond. Should we determine that such a payout is likely, we would record a liability. As of September 30, 2007 we have not recorded a liability with respect to performance bonds.

New Accounting Pronouncements

In February 2007, the FASB Issued SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities-including an amendment of FASB Statement No. 115.” This standard permits entities to choose to measure many financial instruments and certain other items at fair value and provides the opportunity to mitigate volatility in reported earnings caused by measuring related assets and liabilities differently without having to apply complex hedge accounting provisions. This standard is effective for fiscal years beginning after November 15, 2007. We are currently evaluating the provisions of SFAS No. 159.

In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements”. SFAS No. 157 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles and expands disclosures about fair value measurements. SFAS No. 157 applies under other accounting pronouncements that require or permit fair value measurements, the FASB having previously concluded in those accounting pronouncements that fair value is the relevant measurement attribute. Accordingly, SFAS No. 157 does not require any new fair value measurements. SFAS No. 157 is effective for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years, with earlier adoption permitted. The provisions of SFAS No. 157 should be applied prospectively as of the beginning of the fiscal year in which it is initially applied, with limited exceptions. We are currently evaluating the provisions of SFAS No. 157.

Our exposure to market risk through financial instruments, such as investments in marketable securities, is limited to interest rate risk and is not material. Our investments in marketable securities consist primarily of corporate debt instruments and are designed, in order of priority, to preserve principal, provide liquidity, and maximize income. Investments are monitored to limit exposure to mortgage-backed securities and similar instruments responsible for the recent turmoil in the credit markets. Interest rates are variable and fluctuate with current market conditions. We do not believe that a 10% change in interest rates would have a material impact on our financial position or results of operation.

The functional currency of all our foreign entities is the U.S. dollar, except for our Windtec subsidiary for which the local currency (Euro) is the functional currency. We monitor foreign currency exposures, but we currently do not hedge currency risk. Cumulative translation adjustments are excluded from net loss and reported as a separate component of stockholders’ equity. Foreign currency transaction gains and losses are included in our net loss and have not been material to date. Future operating results could be impacted by material foreign currency fluctuations. In the future, should foreign currency fluctuations become material, management will review options to limit the financial impact to our operations.

Our management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures as of September 30, 2007. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”), means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of September 30, 2007, our chief executive officer and chief financial officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control Over Financial Reporting

No change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) occurred during the quarter ended September 30, 2007 that has materially affected, or is reasonably likely to materially affect, internal control over financial reporting.

PART II—OTHER INFORMATION

Not Applicable

Various statements included herein, as well as other statements made from time to time by our representatives, which relate to future matters (including but not limited to statements concerning our future operating results or future commercial success) constitute forward looking statements and are made under the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995. There are a number of important factors which could cause our actual results of operations and financial condition in the future to vary from that indicated in such forward looking statements. Factors that may cause such differences include, without limitation, the risks, uncertainties and other information set forth below.

While the following risk factors have been updated to reflect developments subsequent to the filing of our Annual Report on Form 10-K for the fiscal year ended March 31, 2007, there have been no material changes to the risk factors include in that report, other than the addition of disclosure under the risk factor on page 39 relating to government contracts.

We have a history of operating losses, and we expect to incur losses in the future.

We have been focused on research and development activities through the fiscal year ended March 31, 2007. We have incurred net losses in each year since our inception. Our net loss was $16.3 million for the six months ended September 30, 2007, $34.7 million for the fiscal year ended March 31, 2007, $30.9 million for the fiscal year ended March 31, 2006 and $19.7 million for the fiscal year ended March 31, 2005. Our accumulated deficit as of September 30, 2007 was $401.4 million. We expect to continue to incur operating losses until at least the end of the fiscal year ending March 31, 2009, and we cannot be certain that we will ever achieve profitability.

We had cash, cash equivalents and marketable securities totaling $118.2 million at September 30, 2007. We believe our available cash, cash equivalents and marketable securities will be sufficient to fund our working capital, capital expenditures and other cash requirements for the next several years. However, we may need additional funds if our performance deviates significantly from our current business plan, if there are significant changes in competitive or other market factors, or if unforeseen circumstances arise. Such funds may not be available, or may not be available under terms acceptable to us.

A significant portion of our revenues are derived from a single customer.

Revenue growth in the six months ended September 30, 2007 is being driven largely by our acquisitons, particularly Windtec. Windtec’s largest customer is Sinovel Wind, in China. For the six months ended September 30, 2007, Sinovel accounted for approximately 52% of our total revenues. If Sinovel cancelled contracts, or discontinued future purchases from us, we might be unable to replace the related revenues. This would have a serious negative impact on our operating results and finacial position.

There are a number of technological challenges that must be successfully addressed before our superconductor products can gain widespread commercial acceptance, and our inability to address such technological challenges could adversely affect our ability to acquire customers for our products.

Many of our superconductor products are in the early stages of commercialization, while others are still under development. There are a number of technological challenges that we must successfully address to

27

Table of Contents

complete our development and commercialization efforts for superconductor products. We also believe that several years of further development in the cable, fault current limiter and motor industries will be necessary before a substantial number of additional commercial applications for our HTS wire in these industries can be developed and proven. We will also need to improve the performance and reduce the cost of our HTS wire to expand the number of commercial applications for it. We may be unable to meet such technological challenges or to sufficiently improve the performance and reduce the costs of our HTS wire. Delays in development, as a result of technological challenges or other factors, may result in the introduction or commercial acceptance of our superconductor products later than anticipated.

The commercial uses of superconductor products are limited today, and a widespread commercial market for our products may not develop.

To date, there has been no widespread commercial use of HTS products. Even if the technological hurdles currently limiting commercial uses of HTS products are overcome, it is uncertain whether a robust commercial market for those new and unproven products will ever develop. To date, many projects to install HTS cables and products in power grids have been funded or subsidized by the governmental authorities. If this funding is curtailed, grid operators may not continue to utilize HTS cables and products in their projects. It is possible that the market demands we currently anticipate for our HTS products will not develop and that they will never achieve widespread commercial acceptance.

We have limited experience manufacturing our Power Systems products in commercial quantities, and failure to manufacture our Power Systems products in commercial quantities at acceptable cost and quality levels would impair our ability to meet customer delivery requirements.

To be financially successful, we will have to manufacture our Power Systems products in commercial quantities at acceptable costs while also preserving the necessary performance and quality levels. We cannot be certain that we will be successful in developing product designs and manufacturing processes that permit us to manufacture our Power Systems products in commercial quantities at acceptable costs while preserving the necessary performance and quality. In addition, we may incur significant unforeseen expenses in our product design and manufacturing efforts.

We have not manufactured our 344 superconductors in commercial quantities, and a failure to manufacture our 344 superconductors in commercial quantities at acceptable cost and quality levels would substantially limit our future revenue and profit potential.

We are developing commercial-scale manufacturing processes for our 344 superconductors, which, while very different from our 1G HTS wire manufacturing processes, are also extremely complex and challenging. We expect to have installed and qualified by December 31, 2007 the capacity to manufacture 720,000 meters of our 344 superconductors annually. However, in order to be able to offer our wire at pricing that we believe will be commercially competitive, we estimate that we will need to develop the capacity to manufacture nine million meters of our 344 superconductors annually. We believe it will cost between approximately $28 million and $35 million to purchase and install additional equipment to achieve this commercial scale manufacturing capability. We may not be able to manufacture satisfactory commercial quantities of 344 superconductors of consistent quality with an acceptable yield and cost. Failure to successfully scale up manufacturing of our 344 superconductors would result in a significant limitation of the broad market acceptance of our HTS products and of our future revenue and profit potential.

We have limited experience in marketing and selling our superconductor products and system-level solutions, and our failure to effectively market and sell our products and solutions could adversely affect our revenue and cash flow.

To date, we have limited experience marketing and selling our superconductor products and system-level solutions, and there are few people who have significant experience marketing or selling superconductor products

28

Table of Contents

and system-level solutions. Once our products and solutions are ready for widespread commercial use, we will have to develop a marketing and sales organization that will effectively demonstrate the advantages of our products over both more traditional products and competing superconductor products or other technologies. We may not be successful in our efforts to market this new technology, and we may not be able to establish an effective sales and distribution organization.

We may decide to enter into arrangements with third parties for the marketing or distribution of our products, including arrangements in which our products, such as HTS wire, are included as a component of a larger product, such as a power cable system or a motor. By entering into marketing and sales alliances, the financial benefits to us of commercializing our products are dependent on the efforts of others.

Our success in addressing the wind energy system market is dependent on the system manufacturers that license our system designs.

Because an important element of our strategy for addressing the wind energy system market involves the license of our system designs to manufacturers of wind energy systems, the financial benefits to us of our products for the wind energy market are dependent on the success of these manufacturers in selling wind energy systems that incorporate our designs. We may not be able to enter into marketing or distribution arrangements with third parties on financially acceptable terms, and third parties may not be successful in selling our products or applications incorporating our products.

Growth of the wind energy market depends largely on the availability and size of government subsidies and economic incentives.

At present, the cost of wind energy exceeds the cost of conventional power generation in many locations around the world. Various governments have used different policy initiatives to encourage or accelerate the development and adoption of wind energy and other renewable energy sources. Renewable energy policies are in place in the European Union, most notably Germany and Spain, certain countries in Asia, including China, Japan and South Korea, and many of the states in Australia and the United States. Examples of government sponsored financial incentives include capital cost rebates, feed-in tariffs, tax credits, net metering and other incentives to end-users, distributors, system integrators and manufacturers of wind energy products to promote the use of wind energy and to reduce dependency on other forms of energy. Governments may decide to reduce or eliminate these economic incentives for political, financial or other reasons. Reductions in, or eliminations of, government subsidies and economic incentives before the wind energy industry reaches a sufficient scale to be cost-effective in a non-subsidized marketplace could reduce demand for our products and adversely affect our business prospects and results of operations.

Many of our revenue opportunities are dependent upon subcontractors and other business collaborators.

Many of the revenue opportunities for our business involve projects, such as the installation of superconductor cables in power grids and electrical system hardware in wind energy systems, in which we collaborate with other companies, including suppliers of cryogenic systems, manufacturers of electric power cables and manufacturers of wind energy systems. In addition, a key element of our business strategy is the formation of business alliances with motor manufacturers and/or marine propulsion system integrators. As a result, most of our current and planned revenue-generating projects involve business collaborators on whose performance our revenue is dependent. If these business partners fail to deliver their products or perform their obligations on a timely basis or fail to generate sufficient demand for the systems they manufacture, our revenue from the project may be delayed or decreased and we may not be successful in selling our products.

We may not realize all of the sales expected from our backlog of orders and contracts.

At September 30, 2007, we had approximately $180.3 million of backlog. There can be no assurances that the revenue we expect to generate from our backlog will be realized in the periods we expect to realize such

29

Table of Contents

revenue, or at all. In addition, the backlog of orders, if realized, may not result in profitable revenue. Backlog represents the value of contracts and purchase orders received, less the revenue recognized to date on those contracts and purchase orders. Our customers have the right under some circumstances and with some penalties or consequences to terminate, reduce or defer firm orders that we have in backlog. In addition, our government contracts are subject to the risks described below. If our customers terminate, reduce or defer firm orders, we may be protected from certain costs and losses, but our sales will nevertheless be adversely affected and we may not generate the revenue we expect. Although we strive to maintain ongoing relationships with our customers, there is an ongoing risk that orders may be cancelled or rescheduled due to fluctuations in our customers’ business needs or purchasing budgets.

Our contracts with the U.S. government are subject to audit, modification or termination by the U.S. government, and the continued funding of such contracts remains subject to annual congressional appropriation which, if not approved, could adversely affect our results of operations and financial condition.

As a company that contracts with the U.S. government, we are subject to financial audits and other reviews by the U.S. government of our costs and performance, accounting and general business practices relating to these contracts. Based on the results of these audits, the U.S. government may adjust our contract-related costs and fees. We cannot be certain that adjustments arising from government audits and reviews would not have a material adverse effect on our results of operations. Some of our contracts with the U.S. government are on a firm fixed price basis and, as such, are subject to more financial risk in the event of unanticipated cost overruns. For example, in Fiscal 2006 we announced that we had higher than planned costs in connection with a fixed price contract with the Navy.

All of our U.S. government contracts can be terminated by the U.S. government for its convenience. Termination-for-convenience provisions provide only for our recovery of costs incurred or committed, and for settlement of expenses and profit on work completed prior to termination. In addition to the right of the U.S. government to terminate its contracts with us, U.S. government contracts are conditioned upon the continuing approval by Congress of the necessary spending to honor such contracts. Congress often appropriates funds for a program on a fiscal-year basis even though contract performance may take more than one year. Consequently, at the beginning of many major governmental programs, contracts often may not be fully funded, and additional monies are then committed to the contract only if, as and when appropriations are made by Congress for future fiscal years. We cannot be certain that our U.S. government contracts will not be terminated or suspended in the future. The U.S. government’s termination of, or failure to fully fund, one or more of our contracts would have a negative impact on our operating results and financial condition. Further, in the event that any of our government contracts are terminated for cause, it could affect our ability to obtain future government contracts which could, in turn, seriously harm our ability to develop our technologies and products.

In July 2007, we learned that the United States House of Representatives’ Committee on Energy and Commerce (the “Committee”) and its Subcommittee on Oversight and Investigations has sent a letter to the United States Department of Homeland Security (DHS) indicating that it is reviewing the origins of the sole source contract that DHS awarded to American Superconductor and Consolidated Edison for a project to develop electricity grids in New York City that can withstand major disruptions. As we previously announced, we signed a letter contract on this project on May 18, 2007 with DHS worth $1.7 million, of which DHS will fund $1.1 million. On November 1, 2007, we entered into a second 90 day contract with DHS, covering the period from the expiration of the first 90 contract through November 16, 2007. Total project costs are estimated to be $39.3 million with DHS providing up to $25.0 million of the total project cost.

We have also learned that the Committee sent a letter to the Department of the Navy seeking information and documents regarding completed contracts between the U.S. Navy and us.

30

Table of Contents

The Committee did not state the reason for its review of these matters. On August 2, 2007, we received a letter requesting that we provide certain information to the Committee. We believe we have complied with the committee’s request for information.

Negotiations between us and the DHS regarding the final contract are continuing. While we continue to expect to successfully complete this contract, there can be no assurance that we will do so.

We are becoming increasingly reliant on contracts that require the issuance of performance bonds.

While we have been required to obtain performance bonds in the form of surety bonds or letters of credit in the past, the size of the bonds was not material. Recently, we have entered into contracts which require us to post bonds of significant magnitude. In many instances we are required to deposit cash in escrow accounts as collateral for these instruments which is unavailable to us for general use for significant periods of time. Should we be unable to obtain performance bonds in the future, significant future potential contract revenue could become unavailable to us. Further, should our working capital situation deteriorate, we would not be able to access the escrowed cash to meet working capital requirements.

Our products face intense competition both from superconductor products developed by others and from traditional, non-superconductor products and alternative technologies, which could limit our ability to acquire or retain customers.

The market for superconductor products is intensely competitive. We face competition both from competitors in the superconductor field and from vendors of traditional products and new technologies. There are many companies in the United States, Europe, Japan and China engaged in the development of HTS wire, including EHTS (a division of Bruker Biospin), Evico, Fujikura, Furukawa Electric, Innova Superconductor Technology, Nexans, MetOx, Showa, Sumitomo Electric Industries, SuperPower (a subsidiary of Royal Philips Electronics) and Zenergy. The superconductor industry is characterized by rapidly changing and advancing technology. Our future success will depend in large part upon our ability to keep pace with advancing HTS technology and developing industry standards.

Our power electronic products, such as D-VAR, SVC, or static VAR compensators, or STATCOMS and PQ-SVC products, compete with a variety of other power reliability products such as dynamic voltage restorers, or DVRs, flywheels, battery-based power quality systems and competing power electronic converter systems. The manufacturers of products that compete with our power electronic products and PowerModule products include ABB, Alstom, Mitsubishi Electric, S&C Electric and Siemens.

Our Windtec business faces competition for the supply of wind turbine engineering design services from design engineering firms, such as Garrad Hassan, and from licensors of wind turbine systems, such as Aerodyn, DeWind and REpower. We also face indirect competition in the wind energy market from manufacturers of wind energy systems, such as Gamesa, General Electric, Suzlon and Vestas.

The stand-alone FCL products that we are developing in collaboration with Siemens face competition from several competitors developing alternative solutions, including Beijing Superconductor, Hypertech, Hyundai, Innopower, KEPRI, LS Industrial Systems, Nexans, Rolls-Royce, SC Power, SuperPower and Toshiba. The HTS motor and generator products that we are developing face competition from copper wire-based motors and generators, from permanent magnet motors that are being developed, including by DRS Technologies, and from companies developing HTS rotating machinery, including Converteam, Doosan Heavy Industries & Construction, General Electric, Ishikawajima-Harima Heavy Industries Co., Rockwell and Siemens. Research efforts and technological advances made by others in the superconductor field, in the wind energy market or in other areas with applications to the power quality and reliability markets may render our development efforts obsolete.

Many of our competitors have substantially greater financial resources, research and development, manufacturing and marketing capabilities than we have. In addition, as the HTS wire, HTS electric motors and

31

Table of Contents

generators, and power electronic systems markets develop, other large industrial companies may enter those fields and compete with us. If we are unable to compete successfully, it may harm our business, which in turn may limit our ability to acquire or retain customers.

Third parties have or may acquire patents that cover the materials, processes and technologies we use or may use in the future to manufacture our HTS products, and our success depends on our ability to license such patents or other proprietary rights.

We expect that some or all of the HTS materials, processes and technologies we use in designing and manufacturing our products are or will become covered by patents issued to other parties, including our competitors. If that is the case, we will need to acquire licenses to these patents, successfully contest the validity of these patents or re-engineer our products so that they do not infringe such patents. The owners of these patents may refuse to grant licenses to us, or may be willing to do so only on terms that we find commercially unreasonable. If we are unable to obtain these licenses, we may have to contest the validity or scope of those patents or re-engineer our products to avoid infringement claims by the owners of these patents. It is possible that we will not be successful in contesting the validity or scope of a patent, or that we will not prevail in a patent infringement claim brought against us. Even if we are successful in such a proceeding, we could incur substantial costs and diversion of management resources in prosecuting or defending such a proceeding.

Our patents may not provide meaningful protection for our technology, which could result in us losing some or all of our market position.

We own or have licensing rights under many patents and pending patent applications. However, the patents that we own or license may not provide us with meaningful protection of our technologies and may not prevent our competitors from using similar technologies, for a variety of reasons, such as:

Moreover, we could incur substantial litigation costs in defending the validity of our own patents. We also rely on trade secrets and proprietary know-how to protect our intellectual property. However, our non-disclosure agreements and other safeguards may not provide meaningful protection for our trade secrets and other proprietary information. If the patents that we own or license or our trade secrets and proprietary know-how fail to protect our technologies, our market position may be adversely affected.

Our success is dependent upon attracting and retaining qualified personnel, and our inability to do so could significantly damage our business and prospects.

Our success will depend in large part upon our ability to attract and retain highly qualified research and development, management, manufacturing, marketing and sales personnel. Hiring those persons may be especially difficult due to the specialized nature of our business.

We may acquire additional complementary businesses or technologies, which may require us to incur substantial costs for which we may never realize the anticipated benefits.

We acquired Windtec on January 5, 2007 and Power Quality Systems on April 27, 2007. We may in the future acquire additional complementary businesses or technologies, although we currently have no commitments or agreements. As a result of the Windtec and Power Quality Systems acquisitions and any additional acquisitions we pursue, management’s attention and resources may be diverted from our other businesses. An acquisition may also involve significant purchase price and significant transaction-related expenses.

32

Table of Contents

Achieving the benefits of any acquisition involves additional risks, including:

We cannot ensure that we will realize any of the anticipated benefits of the Windtec and Power Quality Systems acquisitions or any other acquisition, and if we fail to realize these anticipated benefits, our operating performance could suffer.

Our international operations are subject to risks that we do not face in the U.S., which could have an adverse effect on our operating results.

We completed our acquisition of Windtec, an Austrian-based company, on January 5, 2007 and we are expanding our sales and service operations in Austria and the Asia-Pacific region, including a new operation in China. We expect our revenue and operations outside the United States will continue to expand in the future. Our international operations are subject to a variety of risks that we do not face in the U.S., including:

Our overall success in international markets depends, in part, upon our ability to succeed in differing legal, regulatory, economic, social and political conditions. We may not be successful in developing and implementing policies and strategies that will be effective in managing these risks in each country where we do business. Our failure to manage these risks successfully could harm our international operations and reduce our international sales, thus adversely affecting our business, operating results and financial condition.

Our common stock may experience extreme market price and volume fluctuations, which may prevent our stockholders from selling our common stock at a profit and could lead to costly litigation against us that could divert our management’s attention.

The market price of our common stock has historically experienced significant volatility and may continue to experience such volatility in the future. Factors such as technological achievements by us and our competitors, the establishment of development or strategic relationships with other companies, our introduction of commercial products, and our financial performance may have a significant effect on the market price of our common stock. In addition, the stock market in general, and the stock of high technology companies in particular, have in recent years experienced extreme price and volume fluctuations, which are often unrelated to the performance or condition of particular companies. Such broad market fluctuations could adversely affect the market price of our

33

Table of Contents

common stock. Due to these factors, the price of our common stock may decline and investors may be unable to resell their shares of our common stock for a profit. Following periods of volatility in the market price of a particular company’s securities, securities class action litigation has often been brought against that company. If we become subject to this kind of litigation in the future, it could result in substantial litigation costs, a damages award against us and the diversion of our management’s attention.

Pursuant to the 2007 Director Stock Plan, we issued 20,000 unregistered shares of our common stock to Directors on August 3, 2007. The shares of our common stock issued to the Directors were issued in reliance on the exemption from the registration provision of Section 4(2) of the Securities Act of 1933, as amended, relating to sales by the issuer not involving any public offering.
