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 is a leading provider of megawatt-scale solutions that lower the cost of wind power and enhance the performance of the power grid. In the wind power market, the Company enables manufacturers to field wind turbines through its advanced engineering, support services and power electronics products. In the power grid market, the Company enables electric utilities and renewable energy project developers to connect, transmit and distribute power through its transmission planning services and power electronics and superconductor-based products. The Company’s wind and power grid products and services provide exceptional reliability, security, efficiency and affordability to its customers.

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 GAAP. 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 June 30, 2012 and 2011 and the financial position at June 30, 2012.

At June 30, 2012, the Company had cash, cash equivalents, and marketable securities of $65.7 million. The Company experienced a substantial decline in revenues, incurred a net loss of $136.8 million and used $141.0 million of cash for operations during the fiscal year ended March 31, 2012. As a result, the Company reduced its global workforce by approximately 50% and consolidated certain business operations in three locations to reduce facility costs. As of June 30, 2012, the Company had a global workforce of approximately 430 persons.

The Company expects that its cost reduction efforts and anticipated revenue growth will result in a substantial reduction in cash used for operations during the year ending March 31, 2013. The Company plans to closely monitor its expenses and if required, expects to further reduce operating costs and capital spending to enhance liquidity.

On April 4, 2012, the Company completed a private placement of $25.0 million of 7% senior convertible notes (“Convertible Notes”). On June 5, 2012, the Company entered into a Loan and Security Agreement (“Term Loan”), under which the Company borrowed $10.0 million. See Note 10, “Debt”, for further information regarding these debt arrangements, including the covenants, restrictions and events of default under the agreements. The Company is in compliance with the covenants and restrictions included in the Convertible Notes and Term Loan as of the date of this Quarterly Report on Form 10-Q.

The Company believes that its available cash, together with additional reductions in operating costs and capital expenditures that it expects to make if necessary, will be sufficient to fund its operations, capital expenditures and any scheduled cash payments under its debt obligations through June 30, 2013. The Company’s liquidity is highly dependent on its ability to profitably grow revenues, successfully manage adverse purchase commitments, fund and maintain compliance with the covenants and restrictions on its debt obligations, and raise additional capital, as required. The Company may seek additional financing; however, there can be no assurance that financing will be available on commercially acceptable terms or at all.

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, 2012 (fiscal 2011) which are contained in the Company’s Annual Report on Form 10-K.

2. | Stock-Based Compensation

The Company accounts for its stock-based compensation at fair value. The following table summarizes stock-based compensation expense by financial statement line item for the three months ended June 30, 2012 and 2011 (in thousands):

|  | Three months ended June 30, |
|  | 2012 |  |  | 2011 |
Cost of revenues |  | $ | 170 |  |  | $ | 329 |
Research and development |  |  | 562 |  |  |  | 660 |
Selling, general and administrative |  |  | 1,262 |  |  |  | 2,477 |
Total |  | $ | 1,994 |  |  | $ | 3,466 |

During the three months ended June 30, 2012, the Company granted approximately 427,000 stock options and issued 214,886 shares of common stock in-lieu of cash bonuses, which vested immediately, to employees under the 2007 Stock Incentive Plan. The Company recorded the issuance of stock in-lieu of bonuses as a non-cash issuance of stock to settle liabilities in the unaudited consolidated condensed statement of cash flows. The options granted vest upon the passage of time, generally 3 years. For awards that vest upon the passage of time, expense is being recorded over the vesting period.

The estimated fair value of the Company’s stock-based awards, less expected annual forfeitures, is amortized over the awards’ service period. The total unrecognized compensation cost for unvested outstanding stock options was $6.9 million for the three months ended June 30, 2012. This expense will be recognized over a weighted average expense period of approximately 2.4 years. The total unrecognized compensation cost for unvested outstanding restricted stock was $4.2 million for the three months ended June 30, 2012. This expense will be recognized over a weighted average expense period of approximately 1.6 years.

The weighted-average assumptions used in the Black-Scholes valuation model for stock options granted during the three months ended June 30, 2012 and 2011 are as follows:

|  | Three months ended June 30, |
|  | 2012 |  |  | 2011 |
Expected volatility |  |  | 72.0 | % |  |  | 67.5 | %
Risk-free interest rate |  |  | 0.9 | % |  |  | 1.9 | %
Expected life (years) |  |  | 5.9 |  |  |  | 5.9 |
Dividend yield |  |  | None |  |  |  | None |

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 the average of the five and seven year United States Treasury rates.

3. | Computation of Net (Loss) Income per Common Share

Basic net (loss) income per share (“EPS”) is computed by dividing net (loss) income by the weighted-average number of common shares outstanding for the period. Where applicable, diluted EPS is computed by dividing the net (loss) income 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 months ended June 30, 2012, 6.3 million shares were not included in the calculation of diluted EPS as they were considered anti-dilutive, of which 3.1 million relate to unvested stock options and 3.2 million relate to the issuance of warrants. For the three months ended June 30, 2011, 3.0 million shares of unvested stock options were not included in the calculation of diluted EPS as they were considered anti-dilutive.

4. | Fair Value Measurements

In January 2010, the Financial Accounting Standards Board (“FASB”) issued guidance related to disclosures of fair value measurements. The guidance requires gross presentation of activity within the Level 3 measurement roll-forward and details of transfers in and out of Level 1 and 2 measurements. It also clarifies two existing disclosure requirements on the level of disaggregation of fair value measurements and disclosures on inputs and valuation techniques. A change in the hierarchy of an investment from its current level will be reflected in the period during which the pricing methodology of such investment changes. Disclosure of the transfer of securities from Level 1 to Level 2 or Level 3 will be made in the event that the related security is significant to total cash and investments. The Company did not have any transfers of assets and liabilities between Level 1, Level 2 and Level 3 of the fair value measurement hierarchy during the three months ended June 30, 2012.

A valuation hierarchy for disclosure of the inputs to valuation used to measure fair value has been established. This hierarchy prioritizes the inputs into three broad levels as follows:

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.

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 certificates of deposits and money market accounts.

Marketable Securities

Marketable securities consist primarily of government-backed securities and commercial paper and 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. The Company’s marketable securities generally have maturities of greater than three months from original purchase date but less than twelve months from the date of the balance sheet. The Company determines the appropriate classification of its marketable securities at the time of purchase and re-evaluates such classification as of each balance sheet date. 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.

Derivative Liability

The Company has identified all of the derivatives (“Derivative Liability”) associated with the Convertible Notes which include put rights to require the investor to acquire an additional $15.0 million convertible note and additional warrants, holder change of control redemption rights, issuer optional redemption rights, sale redemption rights and a right to make payment in the form of stock rather than cash if certain equity conditions are met. The Derivative Liability is subject to revaluation at each balance sheet date, and any change in fair value will be recorded as a change in fair value in other income (expense) until the earlier of its exercise or expiration. The Company relies on assumptions in a lattice model to determine the fair value of Derivative Liability. The Company has appropriately valued the Derivative Liability within Level 3 of the valuation hierarchy. See Note 10, “Debt”, for discussion on the Convertible Notes, Derivative Liability and valuation assumptions used.

Warrants

Warrants were issued in conjunction with the Convertible Notes and the Term Loan. See Note 10, “Debt”, for additional information on warrants. These warrants are subject to revaluation at each balance sheet date, and any change in fair value will be recorded as a change in fair value in other income (expense) until the earlier of their exercise or expiration.

The Company relies on assumptions used in a Black-Scholes model to determine the fair value of warrants. The Company has appropriately valued the warrants within Level 3 of the valuation hierarchy. See Note 11, “Warrants and Derivative Liabilities”, for a discussion of the warrants and the valuation assumptions used.

6. | Inventory

The components of inventory at June 30, 2012 and March 31, 2012 are as follows (in thousands):

|  | June 30, 2012 |  |  | March 31, 2012 |
Raw materials |  | $ | 10,117 |  |  | $ | 9,962 |

Deferred program costs |  |  | 1,940 |  |  |  | 2,466 |
Net inventory |  | $ | 28,699 |  |  | $ | 29,256 |

For the three months ended June 30, 2012, the Company recorded an inventory write-down of approximately $0.3 million based on evaluating its ending inventory on hand for excess quantities and obsolescence.

Deferred program costs as of June 30, 2012 and March 31 2012 primarily represent costs incurred on D-VAR turnkey projects and programs accounted for under contract accounting where the Company needs to complete development programs before revenue and costs will be recognized, respectively.

7. | Product Warranty

The Company generally provides a one to three year warranty on its products, commencing upon installation. A provision is recorded upon revenue recognition to cost of revenues for estimated warranty expense based on historical experience.

8. | Income Taxes

For the three months ended June 30, 2012 and 2011, the Company recorded an income tax benefit of $0.8 million and income tax expense of $0.2 million, respectively. The income tax benefit for the three months ended June 30, 2012, was primarily due to a refund of Chinese income taxes of $0.9 million. The Company has provided a valuation allowance against all deferred tax assets as of June 30, 2012, as it is more likely than not that its deferred tax assets are not currently realizable due to the net operating losses incurred by the Company since its inception.

9. | Restructuring

The Company accounts for charges resulting from operational restructuring actions in accordance with ASC Topic 420, Exit or Disposal Cost Obligations (“ASC 420”) and ASC Topic 712, Compensation—Nonretirement Postemployment Benefits (“ASC 712”). In accounting for these obligations, the Company is required to make assumptions related to the amounts of employee severance, benefits, and related costs and the time period over which leased facilities will remain vacant, sublease terms, sublease rates and discount rates. Estimates and assumptions are based on the best information available at the time the obligation arises. These estimates are reviewed and revised as facts and circumstances dictate; changes in these estimates could have a material effect on the amount accrued on the consolidated balance sheet.

During the year ended March 31, 2012, the Company initiated restructuring activities in order to reorganize global operations, streamline various functions of the business, and reduce its global workforce to better reflect the demand for its products. These activities resulted in the reduction of its global workforce by approximately 50%. During the three months ended June 30, 2012, the Company incurred restructuring costs of $0.1 million. These additional charges were paid as of June 30, 2012 and the remaining balance of accrued restructuring is expected to be paid through March 2013.

The following table presents restructuring charges and cash payments (in thousands):

|  | Severance pay and benefits |  |  | Facility exit costs |  |  | Total |
Accrued restructuring balance at April 1, 2012 |  | $ | 680 |  |  | $ | 294 |  |  | $ | 974 |
Charges to operations |  |  | 167 |  |  |  | (39 | ) |  |  | 128 |
Cash payments |  |  | (269 | ) |  |  | (255 | ) |  |  | (524 | )
Accrued restructuring balance at June 30, 2012 |  | $ | 578 |  |  | $ | — |  |  | $ | 578 |

All restructuring charges discussed above are included within restructuring and impairments in the Company’s unaudited condensed consolidated statements of operations. The Company includes accrued restructuring within accounts payable and accrued expenses in the unaudited condensed consolidated balance sheets.

10. | Debt

Senior Convertible Notes

On April 4, 2012, the Company entered into a Securities Purchase Agreement and completed a private placement of $25.0 million of 7% senior convertible notes with Capital Ventures International (“CVI”), an affiliate of Heights Capital Management. After fees and expenses, the net proceeds were $23.2 million. The Convertible Notes have an initial conversion price of $4.85 per share, representing a premium of approximately 20% over AMSC’s closing price on April 3, 2012. The Convertible Notes are payable in monthly installments beginning four months from issuance and ending on

12

##### Table of Contents

October 4, 2014. Monthly payments are payable in cash or common stock at the option of the Company, subject to certain trading volume, stock price and other conditions. The Company registered 10,262,311 shares of common stock which may be used as payment for principal and interest in lieu of cash for resale under the Securities Act as required under a Registration Rights Agreement with CVI.

The Company has accounted for the Convertible Notes as an instrument that has the characteristics of a debt host contract containing several embedded derivative features that would require bifurcation and separate accounting as a derivative instrument pursuant to the provisions of ASC 815. The Company elected not to use the fair value option for the payable of $25M and will record the liability at the stated value under the loan agreement on the date of issuance with no changes in fair value reported in subsequent periods.

The Company has identified the following derivatives associated with the Convertible Notes: put rights to require the investor to acquire an additional $15.0 million convertible note and additional warrant; holder change of control redemption rights; issuer optional redemption rights; sale redemption rights and a right to make payment in the form of the stock rather than cash if certain equity conditions are met. The Company valued these derivatives at $3.8 million upon issuance and recorded the value as a debt discount and a derivative liability. See Note 11, “Warrants and Derivative Liabilities”, for additional information regarding derivative liabilities.

In addition, CVI received a warrant to purchase approximately 3.1 million additional shares of common stock exercisable at a strike price of $5.45 per share, subject to adjustment, until October 4, 2017. Due to certain adjustment provisions within the warrant, it qualified for liability accounting and had a fair value of $7.0 million upon issuance. The Company recorded the value as a debt discount and a warrant liability. See Note 11, “Warrants and Derivative Liabilities”, for additional information regarding the warrant.

The process of valuing financial and derivative instruments utilizes facts and circumstances as of the measurement date as well as certain inputs, assumptions, and judgments that may affect the estimated fair value of the instruments. Upon issuance of the Convertible Notes, the Company determined the initial carrying value of the Convertible Notes to be $25.0 million. In addition, the Company also incurred $1.8 million of legal and origination costs as of the three months ended June 30, 2012, which have been recorded as a discount on the Convertible Notes. The total debt discount, including the embedded derivatives, warrant and legal and origination costs of $12.6 million is being amortized into interest expense over the term of the Convertible Notes using the effective interest method. Under this method, interest expense is recognized each period until the debt instruments reach maturity. If the maturity of the Convertible Notes is accelerated because of prepayment, then the amortization will be accelerated. During the quarter ended June 30, 2012, the Company recorded non-cash interest expense for amortization of the debt discount related to the Convertible Notes of $2.2 million.

The Convertible Notes contain certain covenants and restrictions, including, among others, that for so long as the Convertible Notes are outstanding, the Company will not incur any indebtedness (other than permitted indebtedness under the Convertible Notes), permit liens on its properties (other than permitted liens under the Convertible Notes), make payments on junior securities or make dividends. The Convertible Notes also contain limitations on the transfer of certain assets. Events of default under the Convertible Notes include failure to pay principal or interest as due on the Convertible Notes, failure to deliver registered shares of common stock upon the holders request for conversion of part or all of the Convertible Notes, failure to maintain the Company’s common stock eligible for trading on defined markets, cross defaults to other material indebtedness, receipt of uninsured judgments against the Company in excess of defined limits and other administrative covenants, as defined in the Convertible Notes and related documentation. Upon an event of default, the holders may require the Company to redeem all or any portion of the outstanding principal amount of the Convertible Notes in cash plus a penalty as specified in the agreement. Also, if the Company fails to maintain an effective registration statement covering common stock to be used in settling obligations under the Convertible Notes, the Company will be required to pay a penalty as specified in the agreement.

In addition, subject to certain conditions contained in the definitive agreements, on October 4, 2012, the Company may issue an additional $15 million aggregate principal amount of convertible notes and warrant to the same investor.

Senior Secured Term Loan

On June 5, 2012, the Company entered into a Term Loan with Hercules Technology Growth Capital (“Hercules”), under which the Company borrowed $10.0 million (the “Term Loan”). After the closing fees and expenses, the net proceeds to the Company were $9.7 million. The Term Loan bears interest at a floating per annum rate equal to 11% plus the percentage, if any, by which the prime rate exceeds 3.75%. The Company will make interest only payments beginning July 1, 2012 and continuing through October 1, 2012, after which the Company will repay the loan in equal monthly installments ending on December 1, 2014. The Term Loan is secured by substantially all of the Company’s existing and

13

##### Table of Contents

future assets. In addition, Hercules received a warrant to purchase approximately 139,000 shares of common stock, exercisable at an initial strike price of $3.59 per share, subject to adjustment, until December 5, 2017. Due to certain adjustment provisions within the warrant, it qualified for liability accounting and the fair value of $0.4 million was recorded upon issuance, which the Company recorded as a debt discount and a warrant liability. See Note 11, “Warrants and Derivative Liabilities”, for a discussion on warrants and the valuation assumptions used. The Company will pay an end of term fee of $0.5 million upon the earlier of maturity or prepayment of the loan. The Company has accrued this as of the three months ended June 30, 2012 and recorded a corresponding amount into the debt discount. In addition, the Company incurred $0.3 million of legal and origination costs in the three months ended June 30, 2012, which have been recorded as a debt discount. The total debt discount including the warrant, end of term fee and legal and origination costs of $1.2 million is being amortized into interest expense over the term of the Term Loan using the effective interest method. Under this method, interest expense is recognized each period until the debt instrument reaches maturity. If the maturity of the Term Loan is accelerated because of prepayment, then the amortization will be accelerated. During the quarter ended June 30, 2012, the Company recorded non-cash interest expense for amortization of the debt discount related to the Term Loan of $0.1 million.

The Term Loan contains certain covenants that restrict the Company’s ability to, among other things, incur or assume certain debt, merge or consolidate, materially change the nature of our business, make certain investments, acquire or dispose of certain assets, make guaranties or grant liens on its assets, make certain loans, advances or investments, declare dividends or make distributions or enter into transactions with affiliates. In addition, the Term Loan contains a covenant which requires the Company to maintain a minimum unrestricted cash balance in the United States of at least $10.0 million at the inception of the Term Loan, which will decrease starting November 1, 2012 and monthly thereafter by the amount of principal paid. The events of default under the Term Loan include, but are not limited to, failure to pay amounts due, breaches of covenants, bankruptcy events, cross defaults under other material indebtedness and the occurrence of a material adverse effect and/or change in control. In the case of a continuing event of default, the Lender may, among other remedies, declare due all unpaid principal amounts outstanding and any accrued but unpaid interest and foreclose on all collateral granted to the Lender as security under the Term Loan.

Although the Company is in compliance with the covenants and restrictions under the Convertible Notes and Term Loan as of the date of this Interim Report on Form 10-Q, there can no assurance that the Company will continue to be in compliance.

Interest expense on the Convertible Notes and Term Loan for the three month period ended June 30, 2012 was $2.8 million, which included $2.3 million of non-cash interest expense related to the amortization of the debt discount on the Convertible Notes and Term Loan.

11. | Warrants and Derivative Liabilities

On April 4, 2012, the Company entered into a Securities Purchase Agreement as described in Note 10, which included a warrant to purchase 3.1 million shares of the Company’s common stock. The warrant is exercisable at any time on or after the date that is six months after the issuance of the warrant and entitles CVI to purchase shares of the Company’s common stock for a period of five years from the initial date the warrant becomes exercisable at a price equal to $5.45 per share, subject to certain price-based and other anti-dilution adjustments. The warrant may not be exercised if, after giving effect to the conversion, CVI together with its affiliates would beneficially own in excess of 4.99% of the Company’s common stock. This percentage may be raised to any other percentage not in excess of 9.99% at the option of the holder of the warrant, upon at least 61-days’ prior notice to the Company, or lowered to any other percentage, at the option of CVI, at any time.

The Company accounts for the warrant as a liability due to certain adjustment provisions within the warrant, which requires that it be recorded at fair value. The warrant is subject to revaluation at each balance sheet date and any change in fair value will be recorded as a change in fair value in other income (expense) until the earlier of expiration or its exercise at which time the warrant liability will be reclassified to equity. The Company used the Black-Scholes option pricing model to calculate the fair value of the warrant, using the following assumptions:

|  | April 4, 2012 |  |  | June 30, 2012 |
Risk-free interest rate |  |  | 1.19 | % |  |  | 0.77 | %
Expected annual dividend yield |  |  | 0.0 | % |  |  | 0.0 | %
Expected volatility |  |  | 80.0 | % |  |  | 80.84 | %
Term |  |  | 5.5 years |  |  |  | 5.28 years |
Fair Value |  | $ | 7.0 million |  |  | $ | 8.5 million |

14

##### Table of Contents

The Company recorded the change in the fair value of the CVI warrant of $1.5 million to change in fair value of derivatives and warrants in the three months ended June 30, 2012.

The Company determined certain embedded derivatives issued with the Convertible Notes required accounting as a liability, which requires they be accounted for as a standalone liability subject to revaluation at each balance sheet date with changes in fair value recorded as change in fair value of derivatives and warrants until the earlier of exercise or expiration.

The Company calculated the fair value of the derivative liabilities bifurcated from the Convertible Notes (see Note 10, “Debt”) utilizing an integrated lattice model. The lattice model is an option pricing model that involves the construction of a binomial tree to show the different paths that the underlying asset may take over the option’s life. A lattice model can take into account expected changes in various parameters such as volatility over the life of the options, providing more accurate estimates of option prices than the Black-Scholes model. Following is a summary of the key assumptions used to value the convertible note derivative feature:

|  | April 4, 2012 |  |  | June 30, 2012 |
Expected Volatility |  |  | 75.0 | % |  |  | 71.0 | %
Risk Free Rate |  |  | 0.44 | % |  |  | 0.33 | %
Bond Yield |  |  | 15.0 | % |  |  | 16.0 | %
Recovery Rate |  |  | 30.0 | % |  |  | 30.0 | %
Redeemable |  |  | yes |  |  |  | yes |
Total Time (years) |  |  | 2.5 |  |  |  | 2.28 |
Dilution Effect |  |  | yes |  |  |  | yes |
Indicated Percent of Par |  |  | 117.0 | % |  |  | 121.0 | %
Fair Value |  | $ | 3.7 million |  |  | $ | 4.5 million |

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. To determine the risk-free interest rate an interpolated rate was used based on the two and three year United States Treasury rates. The bond yield was estimated by comparing comparable corporate debt and yield information. The recovery rate of the Convertible Note was estimated by reviewing historical corporate debt that went into default. The bond is redeemable by the Company at any point after the one-year anniversary of the grant date provided certain provisions within the note. The total time is based on the actual contractual terms, 30 months. It was determined that there is a dilution effect based on the Company’s ability to make payments in shares of common stock.

The Company recorded the change in the fair value of the derivative liabilities of $0.8 million to changes in fair value of derivatives and warrants in the three months ended June 30, 2012.

On June 5, 2012, the Company entered into a Loan and Security Agreement with Hercules (see Note 10, “Debt”, for additional information regarding the Loan and Security Agreement). In conjunction with this agreement, the Company issued a warrant to purchase approximately 139,000 shares of the Company’s common stock. The warrant is exercisable at any time after the issuance of the warrant and entitles Hercules to purchase shares of the Company’s common stock for a period of five and half years from the initial date the warrant becomes exercisable at a price equal to $3.59 per share subject to certain price-based and other anti-dilution adjustments.

##### Table of Contents

The Company accounts for the warrant as a liability due to certain provisions within the warrant, which requires that it be recorded at fair value. The warrant is subject to revaluation at each balance sheet date and any change in fair value will be recorded as changes in fair value of derivatives and warrants until the earlier of expiration or its exercise at which time the warrant liability will be reclassified to equity. The Company calculated the fair value of the warrant using the Black-Scholes option pricing model to value the warrant, using the following assumptions:

|  | June 5, 2012 |  |  | June 30, 2012 |
Risk-free interest rate |  |  | 0.77 | % |  |  | 0.80 | %
Expected annual dividend yield |  |  | 0.0 | % |  |  | 0.0 | %
Expected volatility |  |  | 79.9 | % |  |  | 80.32 | %
Term |  |  | 5.5 years |  |  |  | 5.44 years |
Fair Value |  | $ | 0.4 million |  |  | $ | 0.5 million |

The company prepared their estimates for the assumptions used to determine the fair value of the warrants issued in conjunction with both the Convertible Note and Term Loan utilizing the respective terms of the warrants with similar inputs under the Black Scholes valuation method more fully described in Note 2.

The company recorded the change in the fair value of the Hercules warrant of $0.1 million to changes in fair value of derivatives and warrants in the three months ended June 30, 2012.

12. | Commitments and Contingencies

Commitments

Purchase Commitments

The Company periodically enters into non-cancelable purchase contracts in order to ensure the availability of materials to support production of its products. Purchase commitments represent enforceable and legally binding agreements with suppliers to purchase goods or services. The Company periodically assesses the need to provide for impairment on these purchase contracts and record a loss on purchase commitments when required. As of June 30, 2012, the Company recorded a liability for adverse purchase commitments of $17.5 million. During the three months ended June 30, 2012, the Company adjusted its accrual for adverse purchase commitments by $7.3 million due to settlements with certain vendors.

During the fourth quarter of the year ended March 31, 2012, several vendors notified the Company that they had suffered losses as a result of procuring safety stock in anticipation of receiving future purchase orders or contracts from the Company and subsequently three vendors have filed suits through the Chinese legal system seeking payment for inventories held to be delivered under purchase orders and safety stock. The Company has accrued outstanding adverse purchase commitments based on legally binding contracts and purchase orders that were placed with its vendors for parts with no future demand. The vendor claims for safety stock were not supported by valid purchase orders or valid executed contracts and are not considered part of the adverse purchase commitment liability. The claims for safety stock have not been accrued as of June 30, 2012. The Company has determined that although it believes that there is no legally enforceable contract for safety stock and will continue to defend its legal position that it does not owe amounts for safety stock, that it is reasonably possible that a case may be made against the Company under certain situations. As the loss is reasonably possible but not probable, the Company has not accounted for the loss. The Company has determined that the range for this potential loss is between $0 and $4 million.

Contingencies

From time to time, the Company is involved in legal and administrative proceedings and claims of various types. The Company records a liability in its consolidated financial statements for these matters when a loss is known or considered probable and the amount can be reasonably estimated. The Company reviews these estimates each accounting period as additional information is known and adjusts the loss provision when appropriate. If a matter is both probable to result in liability and the amounts of loss can be reasonably estimated, the Company estimates and discloses the possible loss or range of loss. If the loss is not probable or cannot be reasonably estimated, a liability is not recorded in its consolidated financial statements.

Between April 6, 2011 and May 12, 2011, seven putative securities class action complaints were filed against the Company and two of its officers in the United States District Court for the District of Massachusetts; one complaint additionally asserted claims against the underwriters who participated in our November 12, 2010 securities offering. On June 7, 2011, the United States District Court for the District of Massachusetts consolidated these actions under the caption

##### Table of Contents

Lenartz v. American Superconductor Corporation, et al., Docket No. 1:11-cv-10582-WGY. On August 31, 2011, Lead Plaintiff, the Plumbers and Pipefitters National Pension Fund, filed a consolidated amended complaint against the Company, its officers and directors, and the underwriters who participated in our November 12, 2010 securities offering, asserting claims under sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated under the Securities Exchange Act of 1934 (the “Exchange Act”), as well as under sections 11, 12(a)(2) and 15 of the Securities Act of 1933 (the “Securities Act”). The complaint alleges that during the relevant class period, the Company and its officers omitted to state material facts and made materially false and misleading statements relating to, among other things, its projected and recognized revenues and earnings, as well as its relationship with Sinovel Wind Group Co., Ltd. that artificially inflated the value of the Company’s stock price. The complaint further alleges that the Company’s November 12, 2010 securities offering contained untrue statements of material facts and omitted to state material facts required to be stated therein. The plaintiffs seek unspecified damages, rescindment of the Company’s November 12, 2010 securities offering, and an award of costs and expenses, including attorney’s fees. All defendants moved to dismiss the consolidated amended complaint. On December 16, 2011, the district court issued a summary order declining to dismiss the Securities Act claims against the Company and its officers, and taking under advisement the motion to dismiss the Exchange Act claims against the Company and its officers and the motion to dismiss the Securities Act claims made against the underwriters. On July 26, 2012, the district court dismissed the Exchange Act claims against the Company and its officers and denied the motion to dismiss the Securities Act claims made against the underwriters.

Between May 4, 2011 and June 17, 2011, four putative shareholder derivative complaints were filed against the Company (as a nominal defendant) and certain of its directors in the United States District Court for the District of Massachusetts. On July 5, 2011, the District Court consolidated three of these actions, and that matter is now captioned In re American Superconductor Corporation Derivative Litigation, Docket No. 1:11-cv-10784-WGY. On June 1, 2011, the plaintiff in the fourth action, Marlborough Family Revocable Trust v. Yurek, et al., moved to voluntarily dismiss its complaint and refiled its complaint in Superior Court for the Commonwealth of Massachusetts, Middlesex County. On September 7, 2011, the Marlborough action and another putative shareholder derivative complaint filed in Superior Court for the Commonwealth of Massachusetts were consolidated. That consolidated matter is captioned Marlborough Family Revocable Trust v. Yurek, et al., Docket No. 11-1961. On January 12, 2012, an additional shareholder derivative complaint was filed in the Court of Chancery for the State of Delaware. That matter is captioned Krasnoff v. Budhraja, et al., Docket No. 7171. The allegations of the derivative complaints mirror the allegations made in the putative class action complaints described above. The plaintiffs purport to assert claims against the director defendants for breach of fiduciary duty, abuse of control, gross mismanagement, unjust enrichment and corporate waste. The plaintiffs seek unspecified damages on behalf of the Company, as well as an award of costs and expenses, including attorney’s fees.

With respect to the above referenced litigation matters, an estimate of loss or range of loss cannot be made. There are numerous factors that make it difficult to meaningfully estimate possible loss or range of loss at this stage of these litigation matters, including that: the proceedings are in relatively early stages, there are significant factual and legal issues to be resolved, information obtained or rulings made during the lawsuits could affect the methodology for calculation of rescission and the related statutory interest rate. In addition, with respect to claims where damages are the requested relief, no amount of loss or damages has been specified. Therefore, the Company is unable at this time to estimate possible losses. The Company believes that these litigations are without merit, and it intends to defend these actions vigorously. Therefore no adjustment has been made to the financial statements to reflect the outcome of these uncertainties.

On September 13, 2011, the Company commenced a series of legal actions in China against Sinovel Wind Group Co. Ltd. (“Sinovel”). The Company’s Chinese subsidiary, Suzhou AMSC Superconductor Co. Ltd., filed a claim for arbitration with the Beijing Arbitration Commission in accordance with the terms of the Company’s supply contracts with Sinovel. The case is captioned (2011) Jin Zhong An Zi No. 0963. On March 31, 2011, Sinovel refused to accept contracted shipments of 1.5 megawatt (MW) and 3 MW wind turbine core electrical components and spare parts that the Company was prepared to deliver. The Company alleges that these actions constitute material breaches of its contracts because Sinovel did not give it notice that it intended to delay deliveries as required under the contracts. Moreover, the Company alleges that Sinovel has refused to pay past due amounts for prior shipments of core electrical components and spare parts. The Company is seeking compensation for past product shipments and retention (including interest) in the amount of approximately RMB 485 million ($76 million) due to Sinovel’s breaches of its contracts. The Company is also seeking specific performance of our existing contracts as well as reimbursement of all costs and reasonable expenses with respect to the arbitration. The value of the undelivered components under the existing contracts, including the deliveries refused by Sinovel in March 2011, amounts to approximately RMB 4.6 billion ($720 million).

On October 8, 2011, Sinovel filed with the Beijing Arbitration Commission an application under the caption (2011) Jing Zhong An Zi No. 0963, for a counterclaim against the Company for breach of the same contracts under which the Company filed its original arbitration claim. Sinovel claimed, among other things, that the goods supplied by the Company do not conform to the standards specified in the contracts and claimed damages in the amount of approximately RMB 370 million ($58 million). On October 17, 2011, Sinovel filed with the Beijing Arbitration Commission a request for change of counterclaim to increase its damage claim to approximately RMB 1 billion ($157 million). On December 22, 2011, Sinovel filed with the Beijing Arbitration Commission an additional request for change of counterclaim to increase its damages claim to approximately RMB 1.2 billion ($190 million). On February 27, 2012, Sinovel filed with the Beijing Arbitration Commission an application under the caption (2012) Jing Zhong An Zi No. 0157, against the Company for breach of the same contracts under which the Company filed its original arbitration claim. Sinovel claimed, among other things, that the goods supplied by the Company do not conform to the standards specified in the contracts and claimed damages in the amount of approximately RMB 105 million ($17 million). The Company believes that Sinovel’s claims are without merit and it intends to defend these actions vigorously. Since the proceedings in this matter are in relatively early stages, the Company cannot reasonably estimate possible losses or range of losses at this time.

The Company also submitted a civil action application to the Beijing No. 1 Intermediate People’s Court under the caption (2011) Yi Zhong Min Chu Zi No. 15524, against Sinovel for software copyright infringement on September 13, 2011. The application alleges Sinovel’s unauthorized use of portions of the Company’s wind turbine control software source code developed for Sinovel’s 1.5MW wind turbines and the binary code, or upper layer, of the Company’s software for the PM3000 power converters in 1.5MW wind turbines. In July 2011, a former employee of the Company’s Austrian subsidiary was arrested in Austria on charges of economic espionage and fraudulent manipulation of data. In September 2011, the former employee pled guilty to the charges, and was imprisoned. As a result of the Company’s internal investigation and a criminal investigation conducted by Austrian authorities, the Company believes that this former employee was contracted by Sinovel through an intermediary while employed by the Company and improperly obtained and transferred to Sinovel portions of its wind turbine control software source code developed for Sinovel’s 1.5MW wind turbines. Moreover, the Company believes the former employee illegally used source code to develop for Sinovel a software modification to circumvent the encryption and remove technical protection measures on the Company’s PM3000 power converters in 1.5MW wind turbines in the field. The Company is seeking a cease and desist order with respect to the unauthorized copying, installation and use of its software, monetary damages of approximately RMB 38 million ($6 million) for our economic losses and reimbursement of all costs and reasonable expenses. The No. 1 Intermediate People’s Court accepted the case, which was necessary in order for the case to proceed. In November 2011, Sinovel filed a motion to remove this case from the Beijing No. 1 Intermediate People’s Court and transfer the matter to the Beijing Arbitration Commission. On February 14, 2012, the court denied Sinovel’s motion to remove the case. On February 21, 2012, Sinovel filed an appeal of the Beijing No. 1 Intermediate People’s Court decision to the Beijing Higher People’s Court. On April 25, 2012, the Beijing Higher People’s Court issued a final Civil Ruling which supports the Beijing No.1 Intermediate People’s Court’s civil ruling and rejected Sinovel’s appeal. Sinovel has filed an appeal of the Beijing Higher People’s Court’s decision with China’s Supreme People’s Court. On June 18, 2012, Sinovel filed a new motion to remove this case from the Beijing No. 1 Intermediate People’s Court to the court located in Gansu Province.

The Company submitted a civil action application to the Beijing Higher People’s Court against Sinovel and certain of its employees for trade secret infringement on September 13, 2011 under the caption (2011) Gao Min Chu Zi No. 4193. The application alleges the defendants’ unauthorized use of portions of the Company’s wind turbine control software source code developed for Sinovel’s 1.5MW wind turbines as described above with respect to the Copyright Action. The Company is seeking monetary damages of RMB 2.9 billion ($453 million) for the trade secret infringement as well as reimbursement of all costs and reasonable expenses. The Beijing Higher People’s Court accepted the case, which was necessary in order for the case to proceed. On December 22, 2011, the Beijing Higher People’s Court transferred this case to the Beijing No. 1 Intermediate People’s Court under the caption (2011) Gao Min Chu Zi No. 4193. On June 7, 2012, the Company received an Acceptance Notice from the Beijing No.1 Intermediate People’s Court under the caption (2012) Yi Zhong Min Chu Zi No.6833. The Company is currently awaiting notice from the Beijing No. 1 Intermediate People’s Court regarding the first hearing date.

On September 16, 2011, the Company filed a civil copyright infringement complaint in the Hainan Province No. 1 Intermediate People’s Court against Dalian Guotong Electric Co. Ltd. (“Guotong”), a supplier of power converter products to Sinovel, and Huaneng Hainan Power, Inc. (“Huaneng”), a wind farm operator that has purchased Sinovel wind turbines containing Guotong power converter products. The case is captioned (2011) Hainan Yi Zhong Min Chu Zi No. 62. The application alleges that the Company’s PM1000 converters in certain Sinovel wind turbines have been replaced by converters produced by Guotong. Because the Guotong converters are being used in wind turbines containing the Company’s wind turbine control software, the Company believes that its copyrighted software is being infringed. The Company is seeking a cease and desist order with respect to the unauthorized use of its software, monetary damages of RMB 1.2 million ($0.2 million) for its economic losses (with respect to Guotong only) and reimbursement of all costs and reasonable expenses. The

court has accepted the case, which was necessary in order for the case to proceed. In addition, upon the request of the defendant Huaneng, Sinovel has been added by the court to this case as a defendant and Huaneng has been released from this case. In December 2011, Sinovel filed a jurisdiction opposition motion requesting dismissal by the Hainan Province No. 1 Intermediate People’s Court, saying the case should be governed by the Beijing Arbitration Commission. On February 3, 2012, the Company received the Civil Ruling from the court, which granted Sinovel’s motion, and dismissed the entire case. The Company appealed the court’s ruling to the Hainan Higher Court, which on April 5, 2012 upheld the decision of the Hainan Province No. 1 Intermediate People’s Court. On April 9, 2012, the Company filed an appeal of the Hainan Higher Court’s decision with China’s Supreme People’s Court. The Supreme Court accepted the appeal on May 23, 2012. The case is captioned, (2012) Min Shen Zi No. 630.

Ghodawat Energy Pvt Ltd (“Ghodawat”), a company registered in India carrying on the business of wind power development, lodged a Request for Arbitration with the Secretariat of the ICC International Court of Arbitration on May 12, 2011 and named AMSC Windtec GmbH (“AMSC Austria”) as the Respondent. Under the Request for Arbitration, Ghodawat alleges that AMSC Austria breached an agreement dated March 19, 2008 pursuant to which AMSC Austria granted a license to Ghodawat to manufacture, use, sell, market, erect, commission and maintain certain wind turbines using its technical information and wind turbine design (the “License Agreement”). Under the Request for Arbitration, Ghodawat’s claims in this arbitration amount to approximately €18 million ($24 million). AMSC Austria filed an Answer to Request for Arbitration and Counterclaim (“Answer and Counterclaim”), in which AMSC Austria denied Ghodawat’s claims in their entirety. AMSC Austria has also submitted counterclaims under the License Agreement against Ghodawat in the amount of approximately €6 million ($9 million). Ghodawat has filed a Reply to Answer to Request for Arbitration and Counterclaim in which it denies AMSC Austria’s counterclaims. The arbitration proceedings are currently ongoing. The Company has recorded a loss contingency based on its assessment of probable losses on this claim; however this amount is immaterial to its consolidated financial statements.

Other

The Company enters into long-term construction contracts with customers that require the Company to obtain performance bonds. The Company is required to deposit an amount equivalent to some or all the face amount of the performance bonds into an escrow account until the termination of the bond. When the performance conditions are met, amounts deposited as collateral for the performance bonds are returned to the Company. In addition, the Company has various contractual arrangements in which minimum quantities of goods or services have been committed to be purchased on an annual basis.

At June 30, 2012, the Company had $16.7 million of restricted cash included in current assets, and $4.8 million of restricted cash included in long-term assets. These amounts included in restricted cash represent deposits to secure letters of credit for various supply contracts. These deposits are held in interest bearing accounts. The Company is working with its inventory suppliers to delay cash settlements and to reduce the gross liability associated with its adverse purchase commitments. During the quarter ending June 30, 2012, the Company agreed to settle adverse purchase commitments with certain of its vendors. In conjunction with these settlements, the Company agreed to provide letters of credit and bank guarantees in the amount of approximately $9.0 million with expirations through January 31, 2013. The letters of credit and bank guarantees were secured with cash collateral of $8.5 million and resulted in a reduction of its adverse purchase commitments liability of $7.3 million recorded in the three months ended June 30, 2012.

As of June 30, 2012, the Company had three performance bonds in support of customer contracts. The total value of the outstanding performance bonds is $3.5 million with expiration dates through March 2014. In the event that the payment is made in accordance with the requirements of any of these performance bonds, the Company would record the payment as an offset to revenue.

15. | Recent Accounting Pronouncements

In June 2011, the FASB issued Accounting Standards Update (ASU) No. 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income. ASU 2011-05 requires entities to present net income and other comprehensive income in either a single continuous statement or in two separate, but consecutive, statements of net income and other comprehensive income. ASU 2011-05 is effective for fiscal years and interim periods beginning after December 15, 2011. The Company early adopted ASU 2011-05 and it did not have a material impact on the Company’s consolidated results of operations, financial condition, or cash flows.

In September 2011, the FASB issued Accounting Standards Update No. 2011-08, Intangibles — Goodwill and Other (Topic 350). ASU 2011-08 allows entities to first assess qualitatively whether it is necessary to perform the two-step goodwill impairment test. If an entity believes, as a result of its qualitative assessment, that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the quantitative two-step goodwill impairment test is required. An entity has the unconditional option to bypass the qualitative assessment and proceed directly to performing the first step of the goodwill impairment test. ASU 2011-08 is effective for our first quarter of fiscal 2013 but is eligible for early adoption. The Company does not believe adoption of this standard will have an impact on its consolidated results of operations, financial condition, or cash flows.

In December 2011, the FASB issued Accounting Standards Update No. 2011-11, Balance Sheet (Topic 210)-Disclosures about Offsetting Assets and Liabilities (ASU 2011-11). The update requires entities to disclose information about offsetting and related arrangements of financial instruments and derivative instruments. ASU 2011-11 is effective for our first quarter of fiscal 2014. The Company is currently evaluating the impact of adopting ASU 2011-11, but currently does not believe there will be a significant impact on its consolidated results of operations, financial condition, or cash flows.

The Company does not believe that other recently issued accounting pronouncements will have a material impact on its financial statements.

Executive Overview

American Superconductor Corporation was founded in 1987. We are a leading provider of megawatt-scale solutions that lower the cost of wind power and enhance the performance of the power grid. In the wind power market, we enable manufacturers to field wind turbines through our advanced engineering, support services and power electronics products. In the power grid market, we enable electric utilities and renewable energy project developers to connect, transmit and distribute power through our transmission planning services and power electronics and superconductor-based products. Our wind and power grid products and services provide exceptional reliability, security, efficiency and affordability to our customers.

Our wind and power grid solutions help to improve energy efficiency, alleviate power grid capacity constraints and increase the adoption of renewable energy generation. Demand for our solutions is driven by the growing needs for renewable sources of electricity, such as wind and solar energy, and for modernized smart grids that improve power reliability and quality. Concerns about these factors have led to increased spending by corporations as well as supportive government regulations and initiatives on local, state, national and global levels, including renewable portfolio standards, tax incentives and international treaties.

We manufacture products using two proprietary core technologies: PowerModule™ programmable power electronic converters and our Amperium™ HTS wires. These technologies and our system-level solutions are protected by a broad and deep intellectual property portfolio consisting of hundreds of patents and licenses worldwide.

We operate our business under two market-facing business units: Wind and Grid. We believe this market-centric structure enables us to more effectively anticipate and meet the needs of wind turbine manufacturers, power generation project developers and electric utilities.

Our fiscal year begins on April 1 and ends on March 31. This document refers to fiscal 2012, which is defined as the period beginning on April 1, 2012 and concluding on March 31, 2013. The first quarter of fiscal 2012 began on April 1, 2012 and concluded on June 30, 2012.

On April 4, 2012 we completed a private placement of $25.0 million of senior convertible notes (the “Convertible Notes”) with an affiliate of Heights Capital Management. On June 5, 2012, we entered into a $10.0 million Loan and Security Agreement (“Term Loan”) with Hercules Technology Growth Capital. See Liquidity and Capital Resources for further discussion of these debt arrangements.

Our cash requirements depend on numerous factors, including managing our adverse purchase commitments, maintaining compliance with the covenants and restrictions in our debt agreements, successful completion of our product development activities, ability to commercialize our product prototypes, rate of customer and market adoption of our products, collecting receivables according to established terms, and the continued availability of United States 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, diversification of our customer base, and potential strategic alliances. See below for a discussion of liquidity and capital resources.

During March 2011, we engaged in discussions with Sinovel, formerly our largest customer, regarding the acceptance of its scheduled shipments, outstanding receivables, and the delivery of a custom solution desired by Sinovel for low voltage ride through (“LVRT”) that required a modification to our existing LVRT design. The custom design required modified software and additional hardware. Toward the end of March, Sinovel requested that we provide them with the additional hardware without additional cost. On March 31, 2011, we proposed to Sinovel that we would provide the additional hardware without additional cost if Sinovel would accept the scheduled shipments. Sinovel rejected this proposal due to what we were told was excess inventory of our components. Since Sinovel did not give us the requisite notice under our contracts that they intended to delay deliveries, we believe that these actions constitute material breaches of our contracts.

As of the date of this filing, we have not received payment from Sinovel for any outstanding receivables nor have we been notified as to when, if ever, Sinovel will accept contracted shipments that were scheduled for delivery after March 31, 2011. Additionally, based in part upon evidence obtained through an internal investigation and a criminal investigation conducted by Austrian authorities regarding the actions of a former employee of our Austrian subsidiary, we believe that Sinovel illegally obtained and used our intellectual property in violation of civil and criminal intellectual property laws. In July 2011, a former employee of our Austrian subsidiary was arrested in Austria on charges of economic espionage and fraudulent manipulation of data. In September 2011, the former employee pled guilty to the charges, and was imprisoned. The evidence presented during the court hearing showed that this former employee was contracted by Sinovel through an intermediary while employed by us and improperly obtained and transferred to Sinovel portions of our wind turbine control software source code developed for Sinovel’s 1.5MW wind turbines. Except for portions of this 1.5MW wind turbine software, we do not believe that the source code for any other turbines, such as the 3MW, 5MW and 6MW wind turbines that were designed by and co-developed with us have been transferred to Sinovel. Moreover, we believe the evidence shows this former employee illegally used source code to develop for Sinovel a software modification to circumvent the encryption and remove technical protection measures on the PM3000 power converters in 1.5MW wind turbines in the field. We believe that only the binary code, or upper layer, of the PM3000 software developed to circumvent the encryption and remove technical protection measures was transferred to Sinovel. We do not believe that any PM3000 source code was transferred to Sinovel. These actions potentially enable Sinovel to deploy, independent of us, wind turbine control software, including a low voltage ride through solution, on all of its 1.5MW wind turbines in the field. In addition, by having the wind turbine control source code, Sinovel could potentially modify the source code to allow the use of core electrical components, including power converters, from other manufacturers.

On September 13, 2011, we commenced a series of legal actions in China against Sinovel. We filed a claim for arbitration in Beijing, China to compel Sinovel to pay us for past product shipments and to accept all contracted but not yet delivered core electrical components and spare parts under all existing contracts with us. The arbitration claim was filed with the Beijing Arbitration Commission in accordance with the terms of our supply contracts with Sinovel. We also filed civil and criminal complaints against Sinovel.

Critical Accounting Policies and Estimates

The preparation of the unaudited 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. Except as stated below, there were no significant changes in the critical accounting policies during the three months ended June 30, 2012 that were disclosed in our Form 10-K for fiscal 2011, which ended on March 31, 2012.

Fair Value of Financial Instruments

Our financial instruments consist principally of cash and cash equivalents, marketable securities, accounts receivable, accounts payable, accrued expenses, derivatives, warrants, convertible notes and a term loan. The estimated fair values have been determined through information obtained from market sources and management estimates. The carrying amounts of these instruments approximate fair value. We have identified all of the derivatives associated with the Convertible Notes which include put rights to require the investor to acquire an additional $15.0 million convertible note and additional warrant, holder change of control redemption rights, issuer optional redemption rights, sale redemption rights and a right to make payment in the form of stock rather than cash if certain equity conditions are met. The derivative liability is subject to revaluation at each balance sheet date, and any change in fair value will be recorded as a change in fair value in other income (expense) until the earlier of their exercise or expiration of the derivatives associated with the Convertible Notes. We rely on assumptions in a lattice model to determine the fair value of the derivative liability. We have appropriately valued the derivative liability within Level 3 of the valuation hierarchy. Warrants were issued in conjunction with the Convertible Notes and Term Loan. These warrants are subject to revaluation at each balance sheet date, and any change in fair value will be recorded as a change in fair value in other income (expense) until the earlier of the warrants’ exercise or expiration. We rely on assumptions used in a Black-Scholes model to determine the fair value of the warrants. We have appropriately valued the warrants within Level 3 of the valuation hierarchy.

Results of Operations

Three months ended June 30, 2012 compared to the three ended June 30, 2011

Revenues

Total revenues increased by 217% to $28.7 million for the three months ended June 30, 2012, compared to $9.1 million for the three months ended June 30, 2011. Our revenues are summarized as follows (in thousands):

|  | Three months ended June 30, |
|  | 2012 |  |  | 2011 |
Revenues: |  |  |  |  |  |  |  |
Wind |  | $ | 16,511 |  |  | $ | 4,262 |
Grid |  |  | 12,205 |  |  |  | 4,796 |
Total |  | $ | 28,716 |  |  | $ | 9,058 |

Our Wind business unit accounted for 57% of total revenues for the three months ended June 30, 2012, compared to 47% for the three months ended June 30, 2011. Revenues in the Wind business unit increased 287% to $16.5 million in the three months ended June 30, 2012 from $4.3 million in the three months ended June 30, 2011. Wind business unit revenues increased primarily due to increased shipments of electrical control systems to customers in China and India.

Our Grid business unit accounted for 43% of total revenues for the three months ended June 30, 2012, compared to 53% for the three months ended June 30, 2011. Our Grid business unit revenues increased 155% to $12.2 million in the three months ended June 30, 2012 from $4.8 million for the three months ended June 30, 2011. Grid business unit revenues increased primarily due to increased D-VAR revenues.

Total |  | $ | 77,082 |  |  | $ | 59,871 |  |  | $ | 486 |  |  | $ | 1,952 |

These significant projects represented 4% and 41% of the Grid business unit revenues for the three months ended June 30, 2012 and 2011, respectively.

Project HYDRA is a project with Consolidated Edison, Inc. which is being partially funded by the Department of Homeland Security (“DHS”). DHS is expected to invest up to a total of $29.0 million in the development of a new HTS power grid technology called FaultBlocker™ cable systems. FaultBlocker TM cable systems are designed to utilize customized Amperium™ HTS wires, and ancillary controls to deliver more power through the grid while also being able to suppress power surges that can disrupt service. On June 29, 2012, DHS committed an additional $3.3 million in funding on Project HYDRA. Of the total $29.0 million in funding expected from DHS, it has committed funding of $18.9 million to us as of June 30, 2012. Consolidated Edison and Southwire Company are our subcontractors on this project.

LIPA II is a project to install an HTS power cable using our Amperium™ wire for the Long Island Power Authority. DOE-FCL is a project to develop and demonstrate a transmission voltage SuperLimiter fault current limiter (“FCL”).

The following table sets forth customers who represented 10% or more of our total revenues for the three months ended June 30, 2012 and 2011:

Cost of Revenues and Gross Margin

Cost of revenues was $17.0 million for each of the three months ended June 30, 2012 and 2011. Gross margin was 41.1% and (87.2%) for the three months ended June 30, 2012 and 2011, respectively. The increase in gross margin for the three months ended June 30, 2012 as compared to the same period in fiscal 2011 was primarily due to settlements of certain adverse purchase order liabilities resulting in a benefit to cost of revenues of $7.3 million in the three months ended June 30, 2012 as well as higher revenues, which included approximately $3 million of revenue from Chinese customers representing payment for past shipments for which revenue is being recognized upon cash collection. Costs associated with this revenue were recorded in prior periods.

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 June 30, |
|  | 2012 |  |  | 2011 |
R&D expenses per unaudited condensed consolidated statements of operations |  | $ | 3,910 |  |  | $ | 8,136 |
R&D expenditures reclassified as cost of revenues |  |  | 2,860 |  |  |  | 4,040 |
R&D expenditures offset by cost-sharing funding |  |  | 94 |  |  |  | 34 |
Aggregated R&D expenses |  | $ | 6,864 |  |  | $ | 12,210 |

R&D expenses (exclusive of amounts classified as cost of revenues and amounts offset by cost-sharing funding) decreased by 52% to $3.9 million for the three months ended June 30, 2012 from $8.1 million for the three months ended June 30, 2011. The decrease in R&D expenses was driven primarily by the realization of cost reduction actions that were implemented in fiscal 2011. The decrease in R&D expenditures reclassified to costs of revenue was a result of decreased activity under license and development contracts for wind turbine designs compared to the prior year. Aggregated R&D expenses, which include amounts classified as cost of revenues and amounts offset by cost-sharing funding, decreased 44% to $6.9 million for the three months ended June 30, 2012 compared to $12.2 million for the three months ended June 30, 2011.

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 unaudited condensed consolidated statements of income 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 revenues rather than as R&D expenses, as discussed above.

Selling, general, and administrative

SG&A expenses decreased by 37% to $13.8 million in the three months ended June 30, 2012, from $22.0 million in the three months ended June 30, 2011. The decrease in SG&A expenses was due primarily to the realization of cost reductions actions that were implemented in fiscal 2011 and costs associated with the severance of our former chief executive officer during the three months ended June 30, 2011, which did not recur.

Amortization of acquisition related intangibles

We recorded amortization expense related to our core technology and know-how, trade names and trademark intangible assets of $0.1 million and $0.3 million in the three months ended June 30, 2012 and 2011, respectively. These intangible assets are primarily as a result of our Windtec acquisition.

Restructuring

We recorded restructuring and impairment charges of $0.1 million in the three months ended June 30, 2012. These amounts consist primarily of employee severance and benefit costs related to our restructuring plan.

Operating (loss) income

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

|  | Three months ended June 30, |
|  | 2012 |  |  | 2011 |
Wind |  | $ | 1,301 |  |  | $ | (24,370 | )
Grid |  |  | (5,343 | ) |  |  | (10,552 | )
Unallocated corporate expenses |  |  | (2,086 | ) |  |  | (3,405 | )
Total |  | $ | (6,128 | ) |  | $ | (38,327 | )

##### Table of Contents

Our Wind segment generated operating income of $1.3 million in the three months ended June 30, 2012, compared to an operating loss of $24.4 million in the three months ended June 30, 2011. The increase in Wind business unit operating income was primarily due to the settlement of certain adverse purchase order liabilities and the realization of cost reductions which were implemented in fiscal 2011 as well as the increased revenue for the 2012 quarter.

The operating loss of our Grid segment decreased to $5.3 million in the three months ended June 30, 2012, compared to $10.6 million in the three months ended June 30, 2011. The decrease in Grid business unit operating loss was primarily due to lower operating expenses as a result of the reductions in force and reduced discretionary spending, partially offset by increased D-VAR revenues.

Unallocated corporate expenses also include stock-based compensation expense of $2.0 million and $3.5 million for the three months ended June 30, 2012 and 2011, respectively.

Change in fair value of derivatives and warrants

As a result of our completed debt financings during the three months ended June 30, 2012, we recognized a liability for derivative features embedded within the financing agreements, including the convertible feature of the Convertible Note and warrants issued in conjunction with the Convertible Note and Term Loan. We are required to value the derivative liabilities and warrants at fair value each quarter and recognize a gain or loss on the change in fair value of these instruments.

The fair value of the derivative liabilities and warrants increased by $2.4 million and resulted in an expense to our consolidated statement of operations. The primary driver of the expense was the increase in our stock price from the inception of the debt agreements to June 30, 2012.

Interest (expense) income, net

Interest expense, net, was $2.7 million in the three months ended June 30, 2012, compared to interest income of $0.2 million for the three months ended June 30, 2011. The increase in interest expense was due to the debt financings completed during the three months ended June 30, 2012.

Other income, net

Other income, net, was $0.1 million in the three months ended June 30, 2012 compared to $0.6 million for the three months ended June 30, 2011. The decrease in other income, net primarily relates to an increase in losses on minority interest investments of $0.4 million.

Income Taxes

In the three months ended June 30, 2012, we recorded an income tax benefit of $0.8 million compared to income tax expense of $0.2 million in the three months ended June 30, 2011. The decrease in income tax expense was primarily due to a refund of Chinese income taxes.

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.

##### Table of Contents

We define non-GAAP net (loss) income as net (loss) income before amortization of acquisition-related intangibles, restructuring and impairments, stock-based compensation, change in fair value of derivative liabilities and warrants, non-cash interest expense, other unusual charges and any tax effects related to these items. We believe non-GAAP net (loss) income assists management and investors in comparing our performance across reporting periods on a consistent basis by excluding these non-cash or non-recurring charges that we do not believe are indicative of our core operating performance. We also regard non-GAAP net (loss) income as a useful measure of operating performance which more closely aligns net (loss) income with cash used in/provided by continuing operations. In addition, we use non-GAAP net (loss) income as a factor in evaluating management’s performance when determining incentive compensation and to evaluate the effectiveness of our business strategies. A reconciliation of non-GAAP to GAAP net (loss) income is set forth in the table below (in thousands, except per share data):

|  | Three months ended June 30, |
|  | 2012 |  |  | 2011 |
Net loss |  | $ | (10,275 | ) |  | $ | (37,679 | )

Weighted average shares outstanding * |  |  | 51,191 |  |  |  | 50,709 |

* | Diluted shares are used for periods where net income is generated.

We incurred a non-GAAP net loss of ($10.2) million or ($0.20) per share, for the three months ended June 30, 2012, compared to a non-GAAP net loss of ($30.8) million, or ($0.61) per share, for the three months ended June 30, 2011. The decrease in the non-GAAP net loss was driven primarily by the factors that resulted in a lower net loss, including higher revenues, improved gross margin and lower operating expenses.

Liquidity and Capital Resources

At June 30, 2012, we had cash, cash equivalents, marketable securities and restricted cash of $87.1 million, compared to $66.2 million at March 31, 2012, an increase of $20.9 million. Our cash and cash equivalents, marketable securities and restricted cash are summarized as follows (in thousands):

|  | June 30, 2012 |  |  | March 31, 2012 |
Cash and cash equivalents |  | $ | 60,487 |  |  | $ | 46,279 |
Marketable securities |  |  | 5,209 |  |  |  | 5,304 |
Restricted cash |  |  | 21,451 |  |  |  | 14,626 |
Total cash, cash equivalents, marketable securities and restricted cash |  | $ | 87,147 |  |  | $ | 66,209 |

With respect to the unaudited condensed consolidated statement of cash flows, for the three months ended June 30, 2012, net cash used in operating activities was $11.6 million compared to $57.8 million for the three months ended June 30, 2011. The decrease in net cash used in operations is due primarily to a decrease in net loss, adjusted for non-cash items of $22.3 million and a decrease in cash used for working capital of $23.9 million.

For the three months ended June 30, 2012, net cash used in investing activities was $6.8 million compared to net cash provided by investing activities of $59.8 million for the three months ended June 30, 2011. The decrease in net cash provided by investing activities for the three months ended June 30, 2012 was driven primarily by a decrease in the proceeds from the maturity of marketable securities of $90.7 million and an increase in restricted cash of $3.1 million, partially offset by a decrease in capital expenditures of $4.4 million, and the $20.6 million advance payment to The Switch, and the additional minority investment in Tres Amigas of $1.8 million during the three months ended June 30, 2011, which did not recur.

##### Table of Contents

For the three months ended June 30, 2012, net cash provided by financing activities was $32.9 million compared to $4.4 million in the three months ended June 30, 2011. The increase in net cash provided by financing activities is primarily due to the net proceeds from our financings during the period ended June 30, 2012 of $32.9 million, partially offset by a payment on borrowings under a line of credit of $4.6 million during the three months ended June 30, 2011.

At June 30, 2012, we had $16.7 million of restricted cash included in current assets, and $4.8 million of restricted cash included in long-term assets. These amounts included in restricted cash represent deposits to secure letters of credit for various supply contracts and are held in interest bearing accounts. We are working with our inventory suppliers to delay cash settlements and to reduce the gross liability associated with our adverse purchase commitments, which is approximately $17.5 million as of June 30, 2012. During the quarter ending June 30, 2012, we agreed to settle adverse purchase commitments with certain of our vendors. In conjunction with these settlements, we agreed to provide letters of credit and bank guarantees in the amount of approximately $9.0 million with expirations through January 31, 2013. The letters of credit and bank guarantees were secured with cash collateral of $8.5 million and resulted in a reduction of our adverse purchase commitments liability of $7.3 million.

As of June 30, 2012, we had three performance bonds in support of customer contracts. The total value of the outstanding performance bonds is $3.5 million with expiration dates through March 2014. In the event that the payment is made in accordance with the requirements of any of these performance bonds, we would record the payment as an offset to revenue.

On April 4, 2012, we completed a private placement of $25.0 million of Convertible Notes. The Convertible Notes bear interest of 7% and have an initial conversion price of $4.85 per share. The Convertible Notes are payable in monthly installments beginning four months from issuance and ending on October 4, 2014. Monthly payments are payable in cash or common stock at our option, subject to certain trading volume, stock price and other conditions. The Convertible Notes contain certain covenants and restrictions, including, among others, that for so long as the Convertible Notes are outstanding, we will not incur any indebtedness (other than permitted indebtedness under the Convertible Notes), permit liens on our properties (other than permitted liens under the Convertible Notes), make payments on junior securities or make dividends. The Convertible Notes also contain limitations on the transfer of certain assets. Events of default under the Convertible Notes include failure to pay principal or interest as due on the Convertible Notes, failure to deliver registered shares of common stock upon the holders request for conversion of part or all of the Convertible Notes, failure to maintain our common stock eligible for trading on defined markets, cross defaults to other material indebtedness, receipt of uninsured judgments against us in excess of defined limits and other administrative covenants, as defined in the Convertible Notes and related documentation. Upon an event of default, the holders may require us to redeem all or any portion of the outstanding principal amount of the Convertible Notes in cash plus a penalty specified in the agreement. In addition, if we fail to maintain an effective registration statement covering common stock to be used in settling obligations under the Convertible Notes, we will be required to pay a penalty specified in the agreement.

On June 5, 2012, we entered into a Loan and Security Agreement with Hercules Technology Growth Capital, under which we borrowed $10.0 million. The Term Loan bears interest at a floating per annum rate equal to 11% plus the percentage, if any, by which the prime rate exceeds 3.75%. We will make interest only payments beginning July 1, 2012 and continuing through October 1, 2012, after which we will repay the Term Loan in equal monthly installments ending on December 1, 2014. The Term Loan contains certain covenants that restrict our ability to, among other things, incur or assume certain debt, merge or consolidate, materially change the nature of our business, make certain investments, acquire or dispose of certain assets, make guaranties or grant liens on its assets, make certain loans, advances or investments, declare dividends or make distributions or enter into transactions with affiliates. In addition, the Term Loan contains a covenant which requirements us to maintain a minimum unrestricted cash balance in the United States of at least $10.0 million at the inception of the Term Loan, which will decrease starting November 1, 2012 and monthly thereafter by the amount of principal paid. The events of default under the Term Loan include, but are not limited to, failure to pay amounts due, breaches of covenants, bankruptcy events, cross defaults under other material indebtedness and the occurrence of a material adverse effect and/or change in control. In the case of a continuing event of default, the Lender may, among other remedies, declare due all unpaid principal amounts outstanding and any accrued but unpaid interest and foreclose on all collateral granted to the Lender as security under the Term Loan.

Although we are in and expect to remain in compliance with covenants and restrictions on the Convertible Notes and Term Loan as of the date of this Quarterly Report on Form 10-Q, there can no assurance that we will continue to be in compliance. If we fail to stay in compliance with our covenants or suffer some other event of default, we may be forced to repay the outstanding principle of one or both of our debt obligations. In the case of the Convertible Note, such an event of default would also include the requirement to pay a penalty as defined in the agreement. Should this occur, our liquidity would be adversely affected.

##### Table of Contents

At June 30, 2012, we had cash, cash equivalents, and marketable securities of $65.7 million. We experienced a substantial decline in revenues, incurred a net loss of $136.8 million and used $141.0 million of cash for operations during the fiscal year ended March 31, 2012. As a result, we reduced our global workforce by approximately 50% and consolidated certain business operations in three locations to reduce facility costs. As of June 30, 2012, we had a global workforce of approximately 430 persons.

We expect that our cost reduction efforts and anticipated revenue growth will result in a substantial reduction in cash used for operations during the fiscal year ended March 31, 2013. We plan to closely monitor our expenses and if required, expect to further reduce operating costs and capital spending to enhance liquidity.

We believe that our available cash, together with additional reductions in operating costs and capital expenditures that we expect to make if necessary, will be sufficient to fund our operations, capital expenditures and any scheduled cash payments under our debt obligations through June 30, 2013. Our liquidity is highly dependent on our ability to profitably grow revenues, successfully manage adverse purchase commitments, fund and maintain compliance with the covenants and restrictions on our debt obligations, and raise additional capital, as required. We may seek additional financing however; there can be no assurance that financing will be available on commercially acceptable terms or at all.

Legal Proceedings

We are involved in legal and administrative proceedings and claims of various types. See Part II, Item 1, “Legal Proceedings,” for additional information. We record a liability in our consolidated financial statements for these matters when a loss is known or considered probable and the amount can be reasonably estimated. We review these estimates each accounting period as additional information is known and adjust the loss provision when appropriate. If a matter is both probable to result in liability and the amounts of loss can be reasonably estimated, we estimate and disclose the possible loss or range of loss. If the loss is not probable or cannot be reasonably estimated, a liability is not recorded in its consolidated financial statements.

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 probable, we would record a liability.

In addition, we have various contractual arrangements in which minimum quantities of goods or services have been committed to be purchased on an annual basis.

Recent Accounting Pronouncements

In June 2011, the FASB issued Accounting Standards Update (ASU) No. 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income. ASU 2011-05 requires entities to present net income and other comprehensive income in either a single continuous statement or in two separate, but consecutive, statements of net income and other comprehensive income. ASU 2011-05 is effective for fiscal years and interim periods beginning after December 15, 2011. We early adopted ASU 2011-05 and it did not have a material impact on our consolidated results of operations, financial condition, or cash flows.

In September 2011, the FASB issued Accounting Standards Update No. 2011-08, Intangibles — Goodwill and Other (Topic 350). ASU 2011-08 allows entities to first assess qualitatively whether it is necessary to perform the two-step goodwill impairment test. If an entity believes, as a result of its qualitative assessment, that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the quantitative two-step goodwill impairment test is required. An entity has the unconditional option to bypass the qualitative assessment and proceed directly to performing the first step of the goodwill impairment test. ASU 2011-08 is effective for our first quarter of fiscal 2013 but is eligible for early adoption. We do not believe adoption of this standard will have an impact on our consolidated results of operations, financial condition, or cash flows.

In December 2011, the FASB issued Accounting Standards Update No. 2011-11, Balance Sheet (Topic 210)-Disclosures about Offsetting Assets and Liabilities (ASU 2011-11). The update requires entities to disclose information about offsetting and related arrangements of financial instruments and derivative instruments. ASU 2011-11 is effective for our first quarter of fiscal 2014. We are currently evaluating the impact of adopting ASU 2011-11, but currently believe there will be no significant impact on our consolidated results of operations, financial condition, or cash flows.

We do not believe that other recently issued accounting pronouncements will have a material impact on our financial statements.

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.

Interest Rate Risk

Our exposure to interest rate risk through financial instruments includes investments in marketable securities as well as our Term Loan that carries a variable interest rate. To manage the interest rate exposure on our investments, our strategy is to invest in short-term, highly liquid investments. Our investments in marketable securities consist primarily of government-backed securities and commercial paper and are designed, in order of priority, to preserve principal, provide liquidity, and maximize income. Investments are monitored to limit exposure to instruments responsible for the recent turmoil in the credit markets. Interest rates are variable and fluctuate with current market conditions. Our Term Loan bears interest at a floating per annum rate equal to 11% plus the percentage, if any, by which the prime rate exceeds 3.75%. We do not believe that a 10% change in interest rates would have a material impact on our financial position or results of operations. Our Convertible Note bears a fixed interest rate of 7%; however upon the occurrence on an event of default pursuant to the Note, the interest rate would increase to 15%.

Foreign currency exchange risk

The functional currency of each of our foreign subsidiaries is the U.S. dollar, except for AMSC Austria, for which the local currency (Euro) is the functional currency, and AMSC China, for which the local currency (Renminbi) is the functional currency. The assets and liabilities of AMSC Austria and AMSC China are translated into U.S. dollars at the exchange rate in effect at the balance sheet date and income and expense items are translated at average rates for the period. Cumulative translation adjustments are excluded from net income (loss) and shown as a separate component of stockholders’ equity.

We face exposure to movements in foreign currency exchange rates whenever we, or any of our subsidiaries, enter into transactions with third parties that are denominated in currencies other than our functional currency. Intercompany transactions between entities that use different functional currencies also expose us to foreign currency risk. Gross margins of products we manufacture in the U.S and sell in currencies other than the U.S. dollar are also affected by foreign currency exchange rate movements. In addition, a portion of our earnings is generated by our foreign subsidiaries, whose functional currencies are other than the U.S. dollar, and our revenues and earnings could be materially impacted by movements in foreign currency exchange rates upon the translation of the earnings of such subsidiaries into the U.S. dollar.

Foreign currency transaction gains included in net (loss) income were $0.9 million and $1.2 million for the three months ended June 30, 2012 and 2011, respectively.

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 June 30, 2012. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under 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 that evaluation of our disclosure controls and procedures as of June 30, 2012, 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

There were no changes in our internal control over financial reporting during the quarter ended June 30, 2012 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II—OTHER INFORMATION

ITEM 1. | LEGAL PROCEEDINGS

Between April 6, 2011 and May 12, 2011, seven putative securities class action complaints were filed against us and two of our officers in the United States District Court for the District of Massachusetts; one complaint additionally asserted claims against the underwriters who participated in our November 12, 2010 securities offering. On June 7, 2011, the United States District Court for the District of Massachusetts consolidated these actions under the caption Lenartz v. American Superconductor Corporation, et al., Docket No. 1:11-cv-10582-WGY. On August 31, 2011, Lead Plaintiff, the Plumbers and Pipefitters National Pension Fund, filed a consolidated amended complaint against us, our officers and directors, and the underwriters who participated in our November 12, 2010 securities offering, asserting claims under sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated under the Securities Exchange Act of 1934 (the “Exchange Act”), as well as under sections 11, 12(a)(2) and 15 of the Securities Act of 1933 (the “Securities Act”). The complaint alleges that during the relevant class period, we and our officers omitted to state material facts and made materially false and misleading statements relating to, among other things, our projected and recognized revenues and earnings, as well as our relationship with Sinovel Wind Group Co., Ltd. that artificially inflated the value of our stock price. The complaint further alleges that our November 12, 2010 securities offering contained untrue statements of material facts and omitted to state material facts required to be stated therein. The plaintiffs seek unspecified damages, rescindment of our November 12, 2010 securities offering, and an award of costs and expenses, including attorney’s fees. All defendants moved to dismiss the consolidated amended complaint. On December 16, 2011, the district court issued a summary order declining to dismiss the Securities Act claims against us and our officers, and taking under advisement the motion to dismiss the Exchange Act claims against us and our officers and the motion to dismiss the Securities Act claims made against the underwriters. On July 26, 2012, the district court dismissed the Exchange Act claims against us and our officers and denied the motion to dismiss the Securities Act claims made against the underwriters.

Between May 4, 2011 and June 17, 2011, four putative shareholder derivative complaints were filed against us (as a nominal defendant) and certain of our directors in the United States District Court for the District of Massachusetts. On July 5, 2011, the District Court consolidated three of these actions, and that matter is now captioned In re American Superconductor Corporation Derivative Litigation, Docket No. 1:11-cv-10784-WGY. On June 1, 2011, the plaintiff in the fourth action, Marlborough Family Revocable Trust v. Yurek, et al., moved to voluntarily dismiss its complaint and refiled its complaint in Superior Court for the Commonwealth of Massachusetts, Middlesex County. On September 7, 2011, the Marlborough action and another putative shareholder derivative complaint filed in Superior Court for the Commonwealth of Massachusetts were consolidated. That consolidated matter is captioned Marlborough Family Revocable Trust v. Yurek, et al., Docket No. 11-1961. On January 12, 2012, an additional shareholder derivative complaint was filed in the Court of Chancery for the State of Delaware. That matter is captioned Krasnoff v. Budhraja, et al., Docket No. 7171. The allegations of the derivative complaints mirror the allegations made in the putative class action complaints described above. The plaintiffs purport to assert claims against the director defendants for breach of fiduciary duty, abuse of control, gross mismanagement, unjust enrichment and corporate waste. The plaintiffs seek unspecified damages on behalf of us, as well as an award of costs and expenses, including attorney’s fees.

If a matter is both probable to result in liability and the amounts of loss can be reasonably estimated, we estimate and disclose the possible loss or range of loss. With respect to the above referenced litigation matters, such an estimate cannot be made. There are numerous factors that make it difficult to meaningfully estimate possible loss or range of loss at this stage of these litigation matters, including that: the proceedings are in relatively early stages, there are significant factual and legal issues to be resolved, information obtained or rulings made during the lawsuits could affect the methodology for calculation of rescission and the related statutory interest rate. In addition, with respect to claims where damages are the requested relief, no amount of loss or damages has been specified. Therefore, we are unable at this time to estimate possible losses. We believe that these litigations are without merit, and we intend to defend these actions vigorously. Therefore no adjustment has been made to the financial statements to reflect the outcome of these uncertainties.

On September 13, 2011, we commenced a series of legal actions in China against Sinovel Wind Group Co. Ltd. (“Sinovel”). Our Chinese subsidiary, Suzhou AMSC Superconductor Co. Ltd., filed a claim for arbitration with the Beijing Arbitration Commission in accordance with the terms of our supply contracts with Sinovel. The case is captioned (2011) Jin Zhong An Zi No. 0963. On March 31, 2011, Sinovel refused to accept contracted shipments of 1.5 megawatt (MW) and 3 MW wind turbine core electrical components and spare parts that we were prepared to deliver. We allege that these actions constitute material breaches of our contracts because Sinovel did not give us notice that it intended to delay deliveries as

required under the contracts. Moreover, we allege that Sinovel has refused to pay past due amounts for prior shipments of core electrical components and spare parts. We are seeking compensation for past product shipments and retention (including interest) in the amount of approximately RMB 485 million ($76 million) due to Sinovel’s breaches of our contracts. We are also seeking specific performance of our existing contracts as well as reimbursement of all costs and reasonable expenses with respect to the arbitration. The value of the undelivered components under the existing contracts, including the deliveries refused by Sinovel in March 2011, amounts to approximately RMB 4.6 billion ($720 million).

On October 8, 2011, Sinovel filed with the Beijing Arbitration Commission an application under the caption (2011) Jing Zhong An Zi No. 0963, for a counterclaim against us for breach of the same contracts under which we filed our original arbitration claim. Sinovel claimed, among other things, that the goods supplied by us do not conform to the standards specified in the contracts and claimed damages in the amount of approximately RMB 370 million ($58 million). On October 17, 2011, Sinovel filed with the Beijing Arbitration Commission a request for change of counterclaim to increase its damage claim to approximately RMB 1 billion ($157 million). On December 22, 2011, Sinovel filed with the Beijing Arbitration Commission an additional request for change of counterclaim to increase its damages claim to approximately RMB 1.2 billion ($190 million). On February 27, 2012, Sinovel filed with the Beijing Arbitration Commission an application under the caption (2012) Jing Zhong An Zi No. 0157, against us for breach of the same contracts under which we filed our original arbitration claim. Sinovel claimed, among other things, that the goods supplied by us do not conform to the standards specified in the contracts and claimed damages in the amount of approximately RMB 105 million ($17 million). We believe that Sinovel’s claims are without merit and we intend to defend these actions vigorously. Since the proceedings in this matter are in relatively early stages, we cannot reasonably estimate possible losses or range of losses at this time.

We also submitted a civil action application to the Beijing No. 1 Intermediate People’s Court under the caption (2011) Yi Zhong Min Chu Zi No. 15524, against Sinovel for software copyright infringement on September 13, 2011. The application alleges Sinovel’s unauthorized use of portions of our wind turbine control software source code developed for Sinovel’s 1.5MW wind turbines and the binary code, or upper layer, of our software for our PM3000 power converters in 1.5MW wind turbines. In July 2011, a former employee of our Austrian subsidiary was arrested in Austria on charges of economic espionage and fraudulent manipulation of data. In September 2011, the former employee pled guilty to the charges, and was imprisoned. As a result of our internal investigation and a criminal investigation conducted by Austrian authorities, we believe that this former employee was contracted by Sinovel through an intermediary while employed by us and improperly obtained and transferred to Sinovel portions of our wind turbine control software source code developed for Sinovel’s 1.5MW wind turbines. Moreover, we believe the former employee illegally used source code to develop for Sinovel a software modification to circumvent the encryption and remove technical protection measures on the PM3000 power converters in 1.5MW wind turbines in the field. We are seeking a cease and desist order with respect to the unauthorized copying, installation and use of our software, monetary damages of approximately RMB 38 million ($6 million) for our economic losses and reimbursement of all costs and reasonable expenses. The Beijing No. 1 Intermediate People’s Court accepted the case, which was necessary in order for the case to proceed. In November 2011, Sinovel filed a motion to remove this case from the Beijing No. 1 Intermediate People’s Court and to transfer the matter to the Beijing Arbitration Commission. On February 14, 2012, the court denied Sinovel’s motion to remove the case. On February 21, 2012, Sinovel filed an appeal of the Beijing No. 1 Intermediate People’s Court decision to the Beijing Higher People’s Court. On April 25, 2012, the Beijing Higher People’s Court issued a final Civil Ruling which supports the Beijing No.1 Intermediate People’s Court’s civil ruling and rejected Sinovel’s appeal. Sinovel has filed an appeal of the Beijing Higher People’s Court’s decision with China’s Supreme People’s Court. On June 18, 2012, Sinovel filed a new motion to remove this case form the Beijing No. 1 Intermediate People’s Court to the court located in Gansu Province.

We submitted a civil action application to the Beijing Higher People’s Court against Sinovel and certain of its employees for trade secret infringement on September 13 2011 under the caption (2011) Gao Min Chu Zi No. 4193. The application alleges the defendants’ unauthorized use of portions of our wind turbine control software source code developed for Sinovel’s 1.5MW wind turbines as described above with respect to the Copyright Action. We are seeking monetary damages of RMB 2.9 billion ($453 million) for the trade secret infringement as well as reimbursement of all costs and reasonable expenses. The Beijing Higher People’s Court has accepted the case, which was necessary in order for the case to proceed. On December 22, 2011 the Beijing Higher People’s Court transferred the case to the Beijing No. 1 Intermediate People’s Court under the caption (2011) Gao Min Chu Zi No. 4193. On June 7, 2012, we received the Acceptance Notice form the Beijing No.1 Intermediate People’s Court under the caption (2012) Yi Zhong Min Chu Zi No.6833. We are currently awaiting notice from the Beijing No. 1 Intermediate People’s Court regarding the first hearing date.

On September 16, 2011, we filed a civil copyright infringement complaint in the Hainan Province No. 1 Intermediate People’s Court against Dalian Guotong Electric Co. Ltd. (“Guotong”), a supplier of power converter products to Sinovel, and Huaneng Hainan Power, Inc. (“Huaneng”), a wind farm operator that has purchased Sinovel wind turbines containing Guotong power converter products. The case is captioned (2011) Hainan Yi Zhong Min Chu Zi No. 62. The application alleges that our PM1000 converters in certain Sinovel wind turbines have been replaced by converters produced by Guotong. Because the Guotong converters are being used in wind turbines containing our wind turbine control software, we believe that our copyrighted software is being infringed. We are seeking a cease and desist order with respect to the unauthorized use of our software, monetary damages of RMB 1.2 million ($0.2 million) for our economic losses (with respect to Guotong only) and reimbursement of all costs and reasonable expenses. The court has accepted the case, which was necessary in order for the case to proceed. In addition, upon the request of the defendant Huaneng, Sinovel has been added by the court to this case as a defendant and Huaneng has been released from this case. In December 2011, Sinovel filed a jurisdiction opposition motion requesting dismissal by the Hainan Province No. 1 Intermediate People’s Court, saying the case should be governed by the Beijing Arbitration Commission. On February 3, 2012, we received the Civil Ruling from the court, which granted Sinovel’s motion, and dismissed the entire case. We appealed the court’s ruling to the Hainan Higher Court, which on April 5, 2012 upheld the decision of the Hainan Province No. 1 Intermediate People’s Court. On April 9, 2012, we filed an appeal of the Hainan Higher Court’s decision with China’s Supreme People’s Court. The Supreme Court accepted the appeal on May 23, 2012. The case is captioned, (2012) Min Shen Zi No. 630.

Ghodawat Energy Pvt Ltd (“Ghodawat”), a company registered in India carrying on the business of wind power development, lodged a Request for Arbitration with the Secretariat of the ICC International Court of Arbitration on May 12, 2011 and named AMSC Windtec GmbH (“AMSC Austria”) as the Respondent. Under the Request for Arbitration, Ghodawat alleges that AMSC Austria breached an agreement dated March 19, 2008 pursuant to which AMSC Austria granted a license to Ghodawat to manufacture, use, sell, market, erect, commission and maintain certain wind turbines using its technical information and wind turbine design (the “License Agreement”). Under the Request for Arbitration, Ghodawat’s claims in this arbitration amount to approximately €18 million ($24 million). AMSC Austria filed an Answer to Request for Arbitration and Counterclaim (“Answer and Counterclaim”), in which AMSC Austria denied Ghodawat’s claims in their entirety. AMSC Austria has also submitted counterclaims under the License Agreement against Ghodawat in the amount of approximately €6 million ($9.0 million). Ghodawat has filed a Reply to Answer to Request for Arbitration and Counterclaim in which it denies AMSC Austria’s counterclaims. The arbitration proceedings are currently ongoing. We have recorded a loss contingency based on our assessment of probable losses on this claim; however, this amount is immaterial to our consolidated financial statements.
