AMERICAN SUPERCONDUCTOR CORPORATION

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1.       Description of the Business and Basis of Presentation

          American Superconductor Corporation (the “Company” or “AMSC”) was founded on April 9, 1987. The Company offers an array of proprietary technologies and solutions spanning the electric power infrastructure — from generation to delivery to end use. The Company is a leader in renewable energy, providing proven, megawatt-scale wind turbine designs and electrical control systems. The Company also offers a host of Smart Grid technologies for power grid operators that enhance the reliability, efficiency and capacity of the power grid, and seamlessly integrate renewable energy sources into the power infrastructure. These technologies include superconductor power cable systems, grid-level surge protectors and power electronics-based voltage stabilization systems. 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 (“GAAP”) 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 generally accepted accounting principles 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, 2010 and 2009 and the financial position at September 30, 2010. 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 an interim period 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, 2010 (fiscal 2009) which are contained in the Company’s Annual Report on Form 10-K, filed with the SEC on May 27, 2010.

          The Company has performed an evaluation of subsequent events through the time of filing this Quarterly Report on Form 10-Q with the SEC.

Recently Adopted Accounting Pronouncements

          In October 2009, the FASB issued Accounting Standards Update (ASU) No. 2009-13, Multiple-Deliverable Revenue Arrangements, pertaining to the accounting for revenue arrangements with multiple deliverables. Specifically, the new standard requires an entity to allocate consideration at the inception of an arrangement to all of its deliverables based on their relative selling prices. In the absence of the vendor-specific objective evidence or third-party evidence of the selling prices, consideration must be allocated to the deliverables based on management’s best estimate of the selling prices. In addition, the new standard eliminates the use of the residual method of allocation. The new accounting standard supersedes the prior multiple element revenue arrangement accounting rules that were previously used by the Company. The Company adopted this new accounting standard on April 1, 2010 using the prospective method and the adoption did not have a material impact on its condensed consolidated financial statements.

2.       Stock-Based Compensation

          The Company accounts for its stock-based compensation at fair value. The following table summarizes employee stock-based compensation expense by financial statement line item for the three and six months ended September 30, 2010 and 2009 (in thousands):

	Three months ended				Six months ended
	September 30,				September 30,
	2010		2009		2010		2009
Cost of revenues	$	452	$	354	$	835	$	579
Research and development		691		523		1,159		990
Selling, general and administrative		3,183		2,975		5,831		5,349
Total	$	4,326	$	3,852	$	7,825	$	6,918

7

          During the six months ended September 30, 2010, the Company granted approximately 219,000 shares and 324,000 shares of stock options and restricted stock, respectively, to employees under the 2007 Stock Incentive Plan. The restricted stock awards include approximately 86,000 shares of performance-based restricted stock, which will vest upon achievement of certain annual financial and operational performance measurements. The remaining shares granted vest upon the passage of time, generally 3 years. For awards that vest upon the passage of time, expense is being recorded on a straight-line basis over the vesting period. At September 30, 2010, the Company determined that achievement of the performance measures is probable and as such, is recognizing the fair value of the performance-based awards over the estimated performance period of each award.

          The total unrecognized compensation cost for unvested employee stock-based compensation awards outstanding, net of estimated forfeitures, was $22.6 million at September 30, 2010. This expense will be recognized over a weighted-average expense period of 2.2 years.

          The weighted-average assumptions used in the Black-Scholes valuation model for stock options granted during the three and six months ended September 30, 2010 and 2009 are as follows:

	Three months ended						Six months ended
	September 30,						September 30,
	2010			2009			2010			2009
Expected volatility		61.5	%		66.5	%		65.6	%		70.2	%
Risk-free interest rate		1.6	%		2.4	%		2.1	%		2.6	%
Expected life (years)		6.2			4.8			6.2			4.8
Dividend yield	None			None			None			None

          The expected volatility 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 life 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 the average of the five and seven year U.S. Treasury rates for the three and six months ended September 30, 2010 and the five year U.S. Treasury rates for the three and six months ended September 30, 2009. The stock-based compensation expense recognized in the unaudited condensed consolidated statements of income is based on awards that ultimately are expected to vest; therefore, the amount of expense has been reduced for estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Forfeitures were estimated based on historical experience. This analysis is re-evaluated periodically and the forfeiture rate is adjusted as necessary.

3.      Computation of Net Income per Common Share

          Basic earnings per share (“EPS”) is computed by dividing net earnings by the weighted-average number of common shares outstanding for the period. Diluted EPS is computed by dividing the net earnings 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, exercise of stock options and warrants and contingently issuable shares. For the three and six months ended September 30, 2010 and 2009, common equivalent shares of 1.3 million shares and 1.4 million shares, respectively, and 0.9 million shares and 0.8 million shares, respectively, 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, 2010 and 2009 (in thousands, except per share data):

4.       Fair Value Measurements

          The accounting standard for fair value measurements provides a framework for measuring fair value and requires expanded disclosure regarding fair value measurements. Fair value is defined as the price that would be received for an asset or the exit price that would be paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. The accounting standard established a fair value hierarchy which requires an entity to maximize the use of observable inputs, where available. This hierarchy prioritizes the inputs into three broad levels as follows:

Valuation Hierarchy

Level 1  - Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.

Level 2  - Inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability, and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market corroborated inputs).

Level 3  - Unobservable inputs that reflect the Company’s assumptions that market participants would use in pricing the asset or liability. The Company develops these inputs based on the best information available, including its own data.

          A financial asset’s or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

          The following table provides the assets carried at fair value, measured as of September 30, 2010 and March 31, 2010 (in thousands):

	Total		Quoted Prices in		Using Significant Other		Using Significant

Long-term marketable securities		7,342		—		7,342		—

Valuation Techniques

Cash Equivalents

          Cash equivalents consist of highly liquid instruments with maturities of three months or less that are regarded as high quality, low risk investments and are measured using such inputs as quoted prices, and are classified within Level 1 of the valuation hierarchy. Cash equivalents consist principally of money market accounts and corporate debt instruments.

Marketable Securities

          Long-term and short-term marketable securities consist primarily of government-backed securities and sovereign debt are measured using such inputs as quoted prices for identical or similar assets in markets that are not active, inputs other than quoted prices that are observable for the asset (for example, interest rates and yield curves observable at commonly quoted intervals), and inputs that are derived principally from or corroborated by observable market data by correlation or other means, and are classified within Level 2 of the valuation hierarchy. Short-term marketable securities have maturities of greater than three months from original purchase date but less than twelve months from the date of the balance sheet. All marketable securities are considered available-for-sale and are carried at fair value. The Company periodically reviews the realizability of each short-term and long-term marketable security when impairment indicators exist with respect to the security. If an other-than-temporary impairment of value of the security exists, the carrying value of the security is written down to its estimated fair value.

5.       Derivative Financial Instruments

          The Company’s foreign currency risk management strategy is principally designed to mitigate the potential financial impact of changes in the value of transactions and balances denominated in foreign currency resulting from changes in foreign currency exchange rates. The Company’s foreign currency hedging program uses both forward contracts and currency options to manage the foreign currency exposures that exist as part of its ongoing business operations.

Cash Flow Hedges

          The Company hedges a portion of its intercompany sales of inventory over a maximum period of 15 months using forward foreign exchange contracts accounted for as cash flow hedges to mitigate the impact of volatility associated with foreign currency transactions.

          For forward foreign exchange contracts that are designated as cash flow hedges, if they are effective in offsetting the variability of the hedged cash flows, and otherwise meet the hedge accounting criteria, changes in the derivatives value are not included in current earnings but are included in other comprehensive income in stockholders’ equity. The changes in fair value will subsequently be reclassified into earnings as a component of cost of revenues, as applicable, when the forecasted transaction occurs. To the extent that a previously forecasted transaction is no longer an effective hedge, any ineffectiveness measured in the hedging relationship is recorded in earnings in the period it occurs. The Company does not enter into

10

derivative instruments for trading or speculative purposes. Realized gains and losses resulting from these cash flow hedges offset the foreign exchange gains and losses on the underlying transactions being hedged. Gains and losses on derivatives not designated for hedge accounting or representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in other income (expense), net.

          At September 30, 2010, the Company had forward contracts outstanding to hedge cash flow exposure at the Company’s wholly-owned Austrian subsidiary, AMSC Windtec GmbH (“AMSC Windtec”), with aggregate USD equivalent notional amounts of $34.4 million. These contracts will expire at various dates through June 2011. The net gain or loss from these cash flow hedges reported in accumulated other comprehensive income will be reclassified to earnings and recorded in cost of revenues in our condensed consolidated statement of income when the related inventory is sold to third-party customers.

Balance Sheet Hedges

          In addition to cash flow hedges, the Company also enters into foreign currency forward exchange contracts to mitigate the impact of foreign exchange risk related to non-functional currency receivable balances in its foreign entities. The Company does not elect hedge accounting treatment for these hedges, consequently, changes in the fair value of these contracts are recorded within other income (expense), net, in the period which they occur. At September 30, 2010, the Company had forward contracts outstanding with aggregate USD equivalent notional amounts of $58.9 million, which expired in October 2010.

          The fair value amounts of asset derivatives included in prepaid expenses and other current assets and liability derivatives included in accounts payable and accrued expenses in our condensed consolidated balance sheets related to forward foreign exchange contracts as of September 30, 2010 and March 31, 2010 were as follows (in thousands):

Executive Overview

          American Superconductor Corporation was founded in 1987. We offer an array of proprietary technologies and solutions spanning the electric power infrastructure – from generation to delivery to end use. Our company is a leader in renewable energy, providing proven, megawatt-scale wind turbine designs and electrical control systems. We also offer a host of Smart Grid technologies for power grid operators that enhance the reliability, efficiency and capacity of the grid, and seamlessly integrate renewable energy sources into the power infrastructure. These technologies include superconductor power cable systems, grid-level surge protectors and power electronics-based voltage stabilization systems. Our technologies are protected by a broad and deep intellectual property portfolio consisting of hundreds of patents and licenses worldwide.

          Our fiscal year begins on April 1 and ends on March 31. This document refers to fiscal 2010, which is defined as the period beginning on April 1, 2010 and concluding on March 31, 2011. The second quarter of fiscal 2010 began on July 1, 2010 and concluded on September 30, 2010.

          Our revenues are primarily derived from our AMSC Power Systems business unit, which designs and licenses wind turbines and provides electrical systems and controls for those wind turbines; provides a range of products to increase electrical grid capacity and reliability; provides power electronic products that interconnect wind farms and solar power plants to the power grid; and provides products that enhance power quality for industrial operations. Most of the products offered by AMSC Power Systems utilize our proprietary power electronic converters and enabling software. These solutions increase the quantity, quality and reliability of electric power that is produced by renewable energy sources, transmitted by electric utilities or consumed by large industrial entities. The market for these solutions continues to be strong in 2010, particularly in Asia, where the production of wind turbines and demand for wind turbine electrical systems and controls continues to increase rapidly.

          Our AMSC Superconductors business unit designs and develops superconductor products, such as power cables, fault current limiters, generators, motors and degaussing systems; and it manages large-scale superconductor projects. AMSC Superconductors also manufactures the Amperium™ high temperature superconductor (HTS) wire that goes into superconductor products, providing these systems with compelling performance, efficiency, size and weight advantages compared with conventional electrical equipment. Many superconductor product demonstrations have been successfully completed to date and customer interest is increasing, particularly for superconductor power cables and superconductor wind turbine generators. While these systems have not yet been broadly commercialized, we received our first large-scale commercial wire contract in fiscal 2010.

17

          Our strategy for both AMSC Power Systems and AMSC Superconductors is to drive revenue growth and enhance operating results by increasing adoption of our products. We are targeting high-growth segments of the renewable energy and power grid markets with our advanced engineering capabilities, support services and power electronics and superconductor product offerings.

          Our wind power products and services are marketed globally, with a particular focus on the Asia Pacific region and emerging economies where demand for local wind turbine manufacturing has been increasing significantly. Our power grid products and services have historically been marketed primarily in the United States. However, due to increasing grid interconnection requirements for renewable energy sites and rising demands for Smart Grid solutions overseas, our power grid activities and sales have increasingly become global in nature. Although we leverage strategic partnerships and reseller relationships to increase our revenue streams, we address market needs primarily with our direct sales force.

          We currently have offices and operations in 11 countries around the world. Our Devens, Massachusetts facility serves as our corporate headquarters and our center of excellence for superconductor research, development and manufacturing. Our facilities in Wisconsin serve as our center of excellence for power electronics and controls research and development and power grid product manufacturing. Our facility in Suzhou, China serves as our center of excellence for wind turbine power electronics manufacturing. Our facility in Klagenfurt, Austria serves as our center of excellence for wind turbine design and engineering. Our other locations focus primarily on applications engineering, sales and/or field service.

          As of September 30, 2010 and March 31, 2010, we had backlog of approximately $956 million and $588 million, respectively. The increase in backlog was primarily the result of a substantial new order received from our largest customer, Sinovel Wind Co., Ltd. (“Sinovel”). Based on this level of backlog and our pipeline of business, we believe we will be able to continue growing revenue in the remainder of fiscal 2010.

          Our cash requirements depend on numerous factors, including successful completion of our product development activities, ability to commercialize our product prototypes, and the rate of customer and market adoption of our products. 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.

Critical Accounting Policies and Estimates

          The preparation of condensed consolidated financial statements requires that we make estimates and judgments that affect the reported amounts of assets, liabilities, revenues 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. With the exception of changes to our revenue policy as described below, there were no significant changes in the second quarter of fiscal 2010 in our critical accounting policies as disclosed in our Form 10-K for fiscal 2009, which ended on March 31, 2010.

Derivative Contracts

          Our foreign currency risk management strategy is principally designed to mitigate the potential financial impact of changes in the value of transactions and balances denominated in foreign currency resulting from changes in foreign currency exchange rates. Our foreign currency hedging program uses both forward contracts and currency options to manage the foreign currency exposures that exist as part of its ongoing business operations. We recognize all derivatives, including forward currency-exchange contracts, in the balance sheet at fair value.

Cash Flow Hedges

          We hedge a portion of our intercompany sales of inventory over a maximum period of 15 months using forward foreign exchange contracts accounted for as cash flow hedges to mitigate the impact of volatility associated with foreign currency transactions.

18

          For forward foreign exchange contracts that are designated as cash flow hedges, if they are effective in offsetting the variability of the hedged cash flows, and otherwise meet the hedge accounting criteria, changes in the derivatives value are not included in current earnings but are included in other comprehensive income in stockholders’ equity. The changes in fair value will subsequently be reclassified into earnings as a component of cost of revenues, as applicable, when the forecasted transaction occurs. To the extent that a previously forecasted transaction is no longer an effective hedge, any ineffectiveness measured in the hedging relationship is recorded in earnings in the period it occurs. We do not enter into derivative instruments for trading or speculative purposes. Realized gains and losses resulting from these cash flow hedges offset the foreign exchange gains and losses on the underlying transactions being hedged. Gains and losses on derivatives not designated for hedge accounting or representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in other income (expense), net.

Balance Sheet Hedges

          In addition to cash flow hedges, we also enter into foreign currency forward exchange contracts to mitigate the impact of foreign exchange risk related to non-functional currency receivable balances in our foreign entities. We do not elect hedge accounting treatment for these hedges, consequently, changes in the fair value of these contracts are recorded within other income (expense), net, in the period which they occur.

Revenue Recognition

          In October 2009, the FASB issued Accounting Standards Update (ASU) No. 2009-13, Multiple-Deliverable Revenue Arrangements pertaining to the accounting for revenue arrangements with multiple deliverables. Specifically, the new standard requires an entity to allocate consideration at the inception of an arrangement to all of its deliverables based on their relative selling prices. In the absence of the vendor-specific objective evidence (“VSOE”) or third-party evidence (“TPE”) of the selling prices, consideration must be allocated to the deliverables based on management’s best estimate of the selling prices. In addition, the new standard eliminates the use of the residual method of allocation.

          For sales that involve the delivery of multiple elements, we allocate revenue to each undelivered element based on the element’s fair value as determined by VSOE, which is the price charged when that element is sold separately, or TPE. When VSOE and TPE are unavailable, fair value is based on our best estimate of selling price. When our estimates are used to determine fair value, management makes its estimates using reasonable and objective evidence to determine the price. We review VSOE and TPE at least annually. If we conclude we are unable to establish fair values for one or more undelivered elements within a multiple-element arrangement using VSOE we use TPE or our best estimate of the selling price for that unit of accounting, being the price at which the vendor would transact if the unit of accounting were sold by the vendor regularly on a standalone basis.

          The new accounting standard supersedes the prior multiple element revenue arrangement accounting rules that were previously used by us. We adopted this new accounting standard on April 1, 2010 using the prospective method and the adoption did not have a material impact on our condensed consolidated financial statements.

Results of Operations

Three and six months ended September 30, 2010 compared to the three and six months ended September 30, 2009

Revenues

          Total revenues increased by 36% and 35% to $101.5 million and $198.7 million for the three and six months ended September 30, 2010, respectively, from $74.7 million and $147.7 million for the three and six months ended September 30, 2009, respectively.

The increases in AMSC Power Systems business unit revenues were primarily due to higher sales of wind electrical systems and core components, primarily to customers in China. Based on the average Euro and renminbi exchange rates for the second quarter of fiscal 2010, revenues denominated in these foreign currencies translated into U.S. dollars was $0.6 million higher compared to the translation of these revenues using the average exchange rates of these currencies for the second quarter of fiscal 2009.

          For the three and six months ended September 30, 2010, a substantial portion of our revenues was derived from one customer: Sinovel Wind Co., Ltd., a manufacturer of wind turbines based in China. Sales to Sinovel represented 79% and 76% of total revenues for the three and six months ended September 30, 2010, respectively, compared to 76% and 65% for the three and six months ended September 30, 2009, respectively.

          On May 17, 2010, we announced an extension of our supply of core electrical components for 1.5 megawatt (MW) wind turbines to Sinovel through late 2013 under a new contract valued at approximately $445 million.

          Revenues in our AMSC Superconductors business unit consist of contract revenues, sales of our Amperium™ HTS wire sales, revenues under government-sponsored electric utility projects, and other prototype development contracts. AMSC Superconductors business unit revenues are primarily recorded using the percentage-of-completion method. AMSC Superconductors business unit accounted for 3% of total revenues for both the three and six months ended September 30, 2010 respectively, compared to 4% for both the three and six months ended September 30, 2009. AMSC Superconductors business unit revenues were $3.0 million and $5.3 million in the three and six months ended September 30, 2010, respectively, from $2.9 million and $5.2 million for the three and six months ended September 30, 2009, respectively. Revenues from significant AMSC Superconductors government-funded contracts are summarized as follows (in thousands):

          These significant projects represented 74% and 72% of AMSC Superconductors business unit revenues for the three and six months ended September 30, 2010, respectively, compared to 72% and 60% for the three and six months ended September 30, 2009, respectively.

          Project HYDRA is a contract with Consolidated Edison, Inc. which is being partially funded by the U.S. Department of Homeland Security (“DHS”). DHS is expected to invest up to a total of $24.9 million in the development of a new high temperature superconductor power grid technology called FaultBlocker™ cable systems. FaultBlocker cable systems are designed to utilize customized Amperium™ HTS wires, superconductor power cables and ancillary controls to deliver more power through the grid while also being able to suppress power surges that can disrupt service. Of the total $24.9 million in funding expected from DHS, it has committed funding of $12.6 million to us as of September 30, 2010. We recognized $0.4 million in revenues related to the Project HYDRA during the second quarter of fiscal 2010, compared to $0.6 million in the same period of fiscal 2009. Consolidated Edison and Southwire Company are subcontractors to us on this project.

          LIPA I, completed in the first quarter of fiscal 2009, was a project to install an HTS power cable system at transmission voltage using our first generation HTS wire for the Long Island Power Authority. LIPA II is a project to install an HTS power cable utilizing our second generation HTS wire for the Long Island Power Authority. The increase in LIPA project revenues is related to a new phase of the project being underway. DOE-FCL is a project to develop and demonstrate a transmission voltage SuperLimiter fault current limiter (“FCL”). The NAVSEA Motor Study is a project designed to test the 36.5 MW superconductor motor developed for the U.S. Navy.

Cost-sharing funding

          In addition to reported revenues, we also received funding of $0.3 million and $0.5 million for the three and six months ended September 30, 2010, respectively, under U.S. government cost-sharing agreements with the U.S. Air Force and the Department of Energy, compared to $0.4 million and $1.2 million for the three and six months ended September 30, 2009, respectively. The decrease in cost-sharing funding is primarily due to the completion of the NIST Advanced Technology Program. All of our cost-sharing agreements provide funding in support of development work on our Amperium™ HTS wires being done in our 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 execute joint programs with government agencies. Funding from government cost-sharing agreements is recorded as an offset to research and development (“R&D”) and selling, general and administrative (“SG&A”) expenses, rather than as revenues. As of September 30, 2010, we anticipate recognizing an additional $0.2 million offset to R&D and SG&A expenses related to these cost-sharing agreements over the following quarters of this fiscal year.

Cost of Revenues and Gross Margin

          Cost of revenues increased by 32% and 23% to $60.2 million and $118.5 million for the three and six months ended September 30, 2010, respectively, compared to $45.6 million and $96.1 million for the three and six months ended September 30, 2009, respectively. Gross margin was 40.7% and 40.4% for the three and six months ended September 30, 2010, respectively, compared to 38.9% and 35.0%, respectively, for the same periods of fiscal 2009. The increases in gross margin in the three and six months ended September 30, 2010 as compared to the same periods in fiscal 2009 were due primarily to a shift in the mix of products sold towards higher margin wind turbine core electrical component shipments; material cost reductions primarily resulting from the localization of component supply in China for our power electronic converters, which are now manufactured there; as well as favorable foreign exchange effects. Based on the average Euro and renminbi exchange rates for the second quarter of fiscal 2010, cost of revenues denominated in these foreign currencies translated into U.S. dollars was $0.2 million higher compared to the translation of cost of revenues using the average exchange rates of these currencies for the second quarter of fiscal 2009.

Operating Expenses

Research and development

          A portion of our R&D expenditures related to externally funded development contracts has been classified as cost of revenues (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):

	Three months ended				Six months ended
	September 30,				September 30,
	2010		2009		2010		2009
R&D expenses per condensed consolidated statements of income	$	7,857	$	5,416	$	15,192	$	9,944
R&D expenditures reclassified as cost of revenues		2,510		1,360		5,879		2,847
R&D expenditures offset by cost-sharing funding		133		227		274		617
Aggregated R&D expenses	$	10,500	$	7,003	$	21,345	$	13,408

          R&D expenses (exclusive of amounts classified as cost of revenues and amounts offset by cost-sharing funding) increased by 45% and 53% to $7.9 million and $15.2 million, or 8% of revenues, for each of the three and six months ended September 30, 2010, respectively, from $5.4 million and $9.9 million, or 7% of revenues, for each of the three and six months ended September 30, 2009, respectively. The increases in R&D expenses were driven primarily by increased headcount and related labor spending, as well as added material and overhead spending to support new product development in our AMSC Power Systems business unit. The increase in R&D expenditures reclassified to costs of revenue was a result of increased efforts under license and development contracts for wind turbine designs at AMSC Windtec compared to the prior year. Aggregated R&D expenses, which include amounts classified as cost of revenues and amounts offset by cost-sharing funding, increased 50% and 59% to $10.5 million and $21.3 million, or 10% and 11% of revenues, for each of the three and six months ended September 30, 2010, respectively, compared to $7.0 million and $13.4 million, or 9% of revenues, for each of the three and six months ended September 30, 2009, respectively. The increases in fiscal 2010 were driven primarily by the net impact of the factors described above.

          We present aggregated R&D, which is a non-GAAP measure, because we believe this presentation provides useful information on our aggregate R&D spending and because R&D expenses as reported on the condensed consolidated statements of income have been, and may in the future be, subject to significant fluctuations solely as a result of changes in

21

the level of externally funded contract development work, resulting in significant changes in the amount of the costs recorded as costs of revenues rather than as R&D expenses, as discussed above.

Selling, general, and administrative

          SG&A expenses increased by 35% and 37% to $17.1 million and $32.3 million, or 17% and 16% of revenues, in the three and six months ended September 30, 2010, respectively, from $12.7 million and $23.6 million, or 17% and 16% of revenues, for each of the three and six months ended September 30, 2009, respectively. The increases in SG&A expenses were due primarily to higher stock-based compensation expense and higher labor and related costs driven by headcount growth.

Amortization of acquisition related intangibles

          We recorded $0.4 million and $0.8 million in the three and six months ended September 30, 2010, respectively, compared to $0.5 million and $0.9 million in the three and six months ended September 30, 2009, respectively, in amortization expense related to our contractual relationships/backlog, customer relationships, core technology and know-how, trade names and trademark intangible assets.

          We plan to continue to increase our operating expenses in the coming quarters to provide the platform for growth in subsequent years, but expect them to decline in fiscal 2010 as a percent of revenues from fiscal 2009 levels.

Operating income

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

	Three months ended				Six months ended
	September 30,				September 30,
	2010		2009		2010		2009
AMSC Power Systems	$	26,842	$	19,866	$	52,327	$	35,261
AMSC Superconductors		(6,533)		(5,647)		(12,444)		(11,144)
Unallocated corporate expenses		(4,364)		(3,889)		(7,858)		(7,396)
Total	$	15,945	$	10,330	$	32,025	$	16,721

          AMSC Power Systems operating income increased to $26.8 million and $52.3 million in the three and six months ended September 30, 2010, respectively, from $19.9 million and $35.3 million in the three and six months ended September 30, 2009, respectively. The increase in the three and six months ended September 30, 2010 was primarily the result of higher sales, as described above.

          AMSC Superconductors operating loss increased to $6.5 million and $12.4 million in the three and six months ended September 30, 2010, respectively, from $5.6 million and $11.1 million in the three and six months ended September, 30, 2009, respectively. The increase in operating loss for the three and six months ended September 30, 2010 is primarily due to increased operating expenses to support planned operations expansion.

          Unallocated corporate expenses include stock-based compensation expense of $4.3 million and $7.8 million in the three and six months ended September 30, 2010, respectively, compared to $3.9 million and $6.9 million in the three and six months ended September 30, 2009, respectively. Unallocated corporate expenses for the three and six months ended September 30, 2009 included $0.1 million and $0.5 million, respectively, of restructuring charges related primarily to the closure of the Company’s facility in Westborough, Massachusetts.

22

Interest income

          Interest income was $0.2 million and $0.4 million in each of the three and six months ended September 30, 2010 and September 30, 2009, respectively. Due to current economic conditions, yields are low for interest bearing assets.

Other income (expense), net

          Other income (expense), net, was income of $2.4 million and $2.6 million in the three and six months ended September 30, 2010, respectively, compared to expense of $0.9 million and expense of $2.8 million for the three and six months ended September 30, 2009, respectively. Other income (expense), net primarily relates to gains on hedging contracts of $8.0 million and $4.0 million, net foreign currency translation losses of $5.1 million and $0.8 million, and minority interest in the losses of investments in Blade Dynamics and Tres Amigas of $0.5 million and $0.6 million for the three and six months ended September 30, 2010, respectively.

Income Taxes

          In the three and six months ended September 30, 2010, we recorded income tax expense of $8.6 million and $15.9 million, respectively, compared to $5.3 million and $8.2 million in the three and six months ended September 30, 2009, respectively. Income tax expense in all periods was driven primarily by income generated in foreign jurisdictions. We incurred losses in the U.S. during the three and six months of fiscal 2010 and fiscal 2009.

Non-GAAP Measures

          Generally, a non-GAAP financial measure is a numerical measure of a company’s performance, financial position or cash flow that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with GAAP. The non-GAAP measures included in this Form 10-Q, however, should be considered in addition to, and not as a substitute for or superior to, the comparable measure prepared in accordance with GAAP.

          We define non-GAAP net income as net income before amortization of acquisition-related intangibles, restructuring and impairments, stock-based compensation, other unusual charges and any tax effects related to these items. We believe non-GAAP net income is an important measurement for management and investors given the effect that these non-cash or non-recurring charges have on our net income. We regard non-GAAP net income as a useful measure of operating performance which more closely aligns net income with cash earnings generated by continuing operations. A reconciliation of non-GAAP to GAAP net income is set forth in the table below (in thousands, except per share data):

	Three months ended						Six months ended
	September 30,						September 30,
	2010			2009			2010			2009
Net income	$	9,988		$	4,340		$	19,157		$	6,132
Amortization of acquisition-related intangibles		374			460			762			905
Restructuring and impairments		—			117			—			451
Stock-based compensation		4,326			3,852			7,825			6,918
Tax effects		(84	)		(93	)		(167	)		(181	)
Non-GAAP net income	$	14,604		$	8,676		$	27,577		$	14,225
Non-GAAP earnings per share	$	0.32		$	0.19		$	0.60		$	0.32
Weighted average diluted shares outstanding		46,217			45,233			46,099			44,922

          We generated non-GAAP net income of $14.6 million and $27.6 million or $0.32 and $0.60 per diluted share, for the three and six months ended September 30, 2010, compared to a non-GAAP net income of $8.7 million and $14.2 million or $0.19 and $0.32 per diluted share, for the three and six months ended September 30, 2009. The increase in non-GAAP net income was driven primarily by higher net income and, to a lesser extent, higher stock-based compensation expense, which was added back to net income.

23

Liquidity and Capital Resources

          At September 30, 2010, we had cash, cash equivalents, marketable securities and restricted cash of $131.2 million compared to $155.1 million at March 31, 2010, a decrease of $23.9 million. Our cash and cash equivalents, marketable securities and restricted cash are summarized as follows (in thousands):

	September 30,		March 31,
	2010		2010
Cash and cash equivalents	$	52,615	$	87,594
Marketable securities (short and long-term)		73,118		61,811
Restricted cash		5,484		5,713
Total cash, cash equivalents, marketable securities and restricted cash	$	131,217	$	155,118

          The decrease in cash and cash equivalents, marketable securities and restricted cash at September 30, 2010 from March 31, 2010 was due to cash used for working capital, primarily an increase in accounts receivable, and capital expenditures made in support of our effort to scale up our Amperium™ core capacity.

          For the six months ended September 30, 2010, net cash used in operating activities was $1.9 million compared to net cash provided by operating activities of $21.7 million in the six months ended September 30, 2009. The decrease in cash provided by operations is due primarily to an increase in cash used for working capital of $41.0 million, partially offset by our increase of net income of $13.0 million.

          For the six months ended September 30, 2010, net cash used in investing activities was $37.3 million compared to $11.9 million in the six months ended September 30, 2009. The increase in cash used in investing activities was driven primarily by an increase in capital expenditures and the purchased minority investment in Blade Dynamics during the six months ended September 30, 2010.

          For the six months ended September 30, 2010, cash provided by financing activities was $1.6 million compared to $4.1 million in the same period of fiscal 2009. The decrease of cash provided by financing activities was driven by a decrease in proceeds from the exercise of employee stock options.

          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 at least the next twelve months.

          We had unused, unsecured lines of credit consisting of CNY 11.9 million (approximately $1.8 million) and €2.3 million (approximately $3.1 million) as of September 30, 2010. We also have an additional $3.5 million in bank guarantees and letters of credit supported by unsecured lines of credit.

          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, 2010, there were no recorded performance-based liabilities.

24

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

          We face exposure to financial market risks, including adverse movements in foreign currency exchange rates and changes in interest rates. These exposures may change over time as our business practices evolve and could have a material adverse impact on our financial results.

Cash and cash equivalents

          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 government-backed securities and sovereign debt 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.

Foreign currency exchange risk

          Our foreign currency risk management strategy is principally designed to mitigate the potential financial impact of changes in the value of transactions and balances denominated in foreign currency, resulting from changes in foreign currency exchange rates. Our foreign currency hedging program uses both forward contracts and currency options to manage the foreign currency exposures that exist as part of its ongoing business operations. We recognize all derivatives, including forward currency-exchange contracts, in the balance sheet at fair value.

Cash Flow Hedges

          We hedge a portion of our intercompany sales of inventory over a maximum period of 15 months using forward foreign exchange contracts accounted for as cash flow hedges to mitigate the impact of volatility associated with foreign currency transactions.

          For forward foreign exchange contracts that are designated as cash flow hedges, if they are effective in offsetting the variability of the hedged cash flows, and otherwise meet the hedge accounting criteria, changes in the derivatives value are not included in current earnings but are included in other comprehensive income in stockholders’ equity. The changes in fair value will subsequently be reclassified into earnings as a component of cost of revenues, as applicable, when the forecasted transaction occurs. To the extent that a previously forecasted transaction is no longer an effective hedge, any ineffectiveness measured in the hedging relationship is recorded in earnings in the period it occurs. We do not enter into derivative instruments for trading or speculative purposes. Realized gains and losses resulting from these cash flow hedges offset the foreign exchange gains and losses on the underlying transactions being hedged. Gains and losses on derivatives not designated for hedge accounting or representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in other income (expense), net.

          At September 30, 2010, we had forward contracts outstanding to hedge cash flow exposure at AMSC Windtec, with aggregate USD equivalent notional amounts of $34.4 million. These contracts will expire at various dates through June 2011. The net gain or loss from these cash flow hedges reported in accumulated other comprehensive income will be reclassified to earnings and recorded in cost of revenues in our condensed consolidated statement of income when the related inventory is sold to third-party customers.

Balance Sheet Hedges

          In addition to cash flow hedges, we also enter into foreign currency forward exchange contracts to mitigate the impact of foreign exchange risk related to non-functional currency receivable balances in its foreign entities. We do not elect hedge accounting treatment for these hedges, consequently, changes in the fair value of these contracts are recorded within other income (expense), net, in the period which they occur. At September 30, 2010, we had forward contracts outstanding with aggregate USD equivalent notional amounts of $58.9 million, which expired in October 2010.

25

ITEM 4. CONTROLS AND PROCEDURES

     Evaluation of Disclosure Controls and Procedures

          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, 2010. 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, 2010, 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, 2010 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

26

PART II—OTHER INFORMATION

ITEM 1A. RISK FACTORS

          Investing in our common stock involves a high degree of risk. You should carefully consider the risks and uncertainties described in our annual report on Form 10-K for the year ended March 31, 2010 in addition to the other information included in this quarterly report. If any of the risks actually occurs, our business, financial condition or results of operations would likely suffer. In that case, the trading price of our common stock could fall.

          As of September 30, 2010, there have not been any material changes to the risk factors disclosed in our Annual Report on Form 10-K for the fiscal year ended March 31, 2010, although we may disclose changes to such risk factors or disclose additional risk factors from time to time in our future filings with the SEC.
