This Annual Report on Form 10-K contains forward-looking statements within the meaning of Section 21E of the Securities Exchange Act
of 1934, as amended (the Exchange Act). For this purpose, any statements contained herein that relate to future events or conditions, including without limitation, the statements in Part I, Item 1A. Risk Factors and in Part
II under Item 7. Managements Discussion and Analysis of Financial Condition and Results of Operations and located elsewhere herein regarding industry prospects or our prospective results of operations or financial position, may be
deemed to be forward-looking statements. Without limiting the foregoing, the words believes, anticipates, plans, expects, and similar expressions are intended to identify forward-looking statements.
Such forward-looking statements represent managements current expectations and are inherently uncertain. There are a number of important factors that could materially impact the value of our common stock or cause actual results to differ
materially from those indicated by such forward-looking statements. Such factors include: Our success in addressing the wind energy market is dependent on the manufacturers that license our designs; we may not realize all of the sales expected from
our backlog of orders and contracts; our business and operations would be adversely impacted in the event of a failure or security breach of our information technology infrastructure;; our success is dependent upon attracting and retaining qualified
personnel and our inability to do so could significantly damage our business and prospects; we rely upon third-party suppliers for the components and subassemblies of many of our Wind and Grid products, making us vulnerable to supply shortages and
price fluctuations, which could harm our business; many of our revenue opportunities are dependent upon subcontractors and other business collaborators; if we fail to implement our business strategy successfully, our financial performance could be
harmed; problems with product quality or product performance may cause us to incur warranty expenses and may damage our market reputation and prevent us from achieving increased sales and market share; our contracts with the U.S.

government are subject to audit, modification or termination by the U.S. government and include certain other provisions in favor of the government; the continued funding of such contracts
remains subject to annual congressional appropriation which, if not approved, could reduce our revenue and lower or eliminate our profit; we may acquire additional complementary businesses or technologies, which may require us to incur substantial
costs for which we may never realize the anticipated benefits; many of our customers outside of the United States are, either directly or indirectly, related to governmental entities, and we could be adversely affected by violations of the United
States Foreign Corrupt Practices Act and similar worldwide anti-bribery laws outside the United States; we have limited experience in marketing and selling our superconductor products and system-level solutions, and our failure to effectively market
and sell our products and solutions could lower our revenue and cash flow; we have a history of operating losses, and we may incur additional losses in the future; our operating results may fluctuate significantly from quarter to quarter and may
fall below expectations in any particular fiscal quarter; we may require additional funding in the future and may be unable to raise capital when needed; our new debt obligations include certain covenants and other events of default. Should we not
comply with the covenants or incur an event of default, we may be required to repay our debt obligations in cash, which could have an adverse effect on our liquidity; we have recorded a liability for adverse purchase commitments with certain of our
vendors; should we be required to settle these liabilities in cash, our liquidity could be adversely affected; if we fail to maintain proper and effective internal controls over financial reporting, our ability to produce accurate and timely
financial statements could be impaired and may lead investors and other users to lose confidence in our financial data; we may be required to issue performance bonds or provide letters of credit, which restricts our ability to access any cash used
as collateral for the bonds or letters of credit; changes in exchange rates could adversely affect our results from operations; growth of the wind energy market depends largely on the availability and size of government subsidies and economic
incentives; we depend on sales to customers in China, and global conditions could negatively affect our operating results or limit our ability to expand our operations outside of China; changes in Chinas political, social, regulatory and
economic environment may affect our financial performance; our products face intense competition, which could limit our ability to acquire or retain customers; our international operations are subject to risks that we do not face in the United
States, which could have an adverse effect on our operating results; adverse changes in domestic and global economic conditions could adversely affect our operating results; we may be unable to adequately prevent disclosure of trade secrets and
other proprietary information; our patents may not provide meaningful protection for our technology, which could result in us losing some or all of our market position; the commercial uses of superconductor products are limited today, and a
widespread commercial market for our products may not develop; there are a number of technological challenges that must be successfully addressed before our superconductor products can gain widespread commercial acceptance, and our inability to
address such technological challenges could adversely affect our ability to acquire customers for our products; we have not manufactured our Amperium wire in commercial quantities, and a failure to manufacture our Amperium wire in commercial
quantities at acceptable cost and quality levels would substantially limit our future revenue and profit potential; third parties have or may acquire patents that cover the materials, processes and technologies we use or may use in the future to
manufacture our Amperium products, and our success depends on our ability to license such patents or other proprietary rights; our technology and products could infringe intellectual property rights of others, which may require costly litigation
and, if we are not successful, could cause us to pay substantial damages and disrupt our business; we have filed a demand for arbitration and other lawsuits against our former largest customer, Sinovel, regarding amounts we contend are overdue. We
cannot be certain as to the outcome of these proceedings; we have been named as a party to purported stockholder class actions and stockholder derivative complaints, and we may be named in additional litigation, all of which will require significant
management time and attention, result in significant legal expenses and may result in an unfavorable outcome, which could have a material adverse effect on our business, operating results and financial condition; our 7% convertible note contains
warrants and provisions that could limit our ability to repay the note in shares of common stock and should the note be repaid in stock, shareholders could experience significant dilution; our common stock has experienced, and may continue to
experience, significant market price and volume fluctuations, which may prevent our stockholders from selling our common stock at a profit and could lead to costly litigation against us that could divert our managements attention. These and
the important factors discussed under the caption Risk Factors in Part 1. Item 1A of this Form 10-K for the fiscal year ended March 31, 2012, among others, could cause actual results to differ materially from those indicated by
forward- looking statements made herein and presented elsewhere by management from time to time. Any such forward-looking statements represent managements estimates as of the date of this Annual Report on Form 10-K. While we may elect to
update such forward-looking statements at some point in the future, we disclaim any obligation to do so, even if subsequent events cause our views to change. These forward-looking statements should not be relied upon as representing our views as of
any date subsequent to the date of this Annual Report on Form 10-K.

Overview

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.

We were founded in April, 1987 and since our inception, our company has served more than ten
wind turbine manufacturing customers including Beijing JINGCHENG New Energy in China, Inox Wind in India, Hyundai Heavy Industries and Korean Electric Power Corporation in South Korea and TECO in Taiwan. We have also served over 100 customers in the
grid market since our inception, including American Electric Power and Long Island Power Authority in the United States, EDF Group in France and Ergon Energy in Australia. We serve customers globally through a localized sales and field service
presence in our core target markets.

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 and national levels, including renewable portfolio standards, tax
incentives and international treaties. We estimate that the total addressable global market for our wind and grid solutions is nearly $10 billion.

We segment our operations into 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. We have reclassified prior period segment information in the Annual Report on Form 10-K to reflect our new segments.



| |  |  | Wind.Through our Windtec Solutions brand, our Wind segment enables manufacturers to field wind turbines with exceptional
power output, reliability and affordability. We license our highly engineered wind turbine designs, provide extensive customer support services and supply advanced power electronics and control systems to wind turbine manufacturers. Our design
portfolio includes a broad range of drive trains and power ratings up to 10 megawatts. These designs and support services typically lead to sales of our power electronics and software-based control systems, which are designed for optimized
performance, efficiency and grid compatibility.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Grid.Through our Gridtec Solutions brand, our Grid segment enables electric utilities and renewable energy project
developers to connect, transmit and distribute power with exceptional efficiency, reliability and affordability. We provide transmission planning services that allow us to identify power grid congestion, poor power quality and other risks, which
help us determine how our solutions can improve network performance. These services often lead to sales of grid interconnection solutions for wind farms and solar power plants, power quality systems and transmission and distribution cable systems.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Our fiscal year begins on April 1 and ends on March 31. When we refer to a particular fiscal year,
we are referring to the fiscal year beginning on April 1 of that same year. For example, fiscal 2011 refers to the fiscal year beginning on April 1, 2011. Other fiscal years follow similarly.

| |  |  | the demand for renewable sources of electricity, and
| | - |  | ----------------------------------------------------



| |  |  | the demand for modernized, smart power grid infrastructure that alleviates capacity constraints and improves electricity reliability, security and
efficiency.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------

Wind market overview

The market for wind-generated, zero-emission electricity has grown dramatically for more than a decade. According to the Global Wind
Energy Council (the GWEC), more than 41,000 megawatts (MW) of wind generation capacity were added worldwide in 2011, as compared to 38,000 MW in 2010. We expect that the rate of global wind power installations in 2012 will be
roughly equivalent with 2011.

Several factors are driving growth in the wind power market, including substantial government
incentives and mandates that have been established globally, technological improvements, turbine cost reductions and increasing cost competitiveness with existing power generation technologies. According to GWEC, by early 2011, at least 119
countries had some form of national policy support for renewable energy, more than double the 55 countries that provided such support in 2005. Technological advances, declining turbine production cost and increasing prices for fossil fuels continue
to increase the competitiveness of wind versus traditional power generation technologies.

The vast majority of the wind power
capacity installed worldwide to date is onshore. In the future, industry analysts anticipate rapid growth in the offshore wind market due to its advantages in terms of both wind patterns and real estate availability. Industry research firm IHS
Emerging Energy Research expects the installed base of offshore wind power to increase from approximately 3,000 MW at the end of 2010 to nearly 50,000 MW by the end of 2020 as wind turbine power ratings and performance continue to improve and
project costs decline.

Our solutions for the wind market

We address the challenges of the wind energy market by designing and engineering wind turbines, providing extensive support services to
wind turbine manufacturers and manufacturing and selling critical components for wind turbines.



| |  |  | Wind Turbine Designs.    We design and develop entire state-of-the-art onshore and offshore wind turbines with power ratings
up to 10 megawatts for manufacturers who are in the business of producing wind turbines or who plan to enter the business of manufacturing wind turbines. These customers typically pay us licensing fees for wind turbine designs and purchase from us
the core electrical components or complete electrical control systems needed to operate the wind turbines.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Customer Support Services.    We provide extensive customer support services to wind turbine manufacturers. These services
range from providing designs for customers wind turbine manufacturing plants to establishing and localizing their supply chains and training their employees on proper wind turbine installation and maintenance. We believe these services enable
customers to accelerate their entry into the wind turbine manufacturing market and lower the cost of their wind turbine platforms.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Electrical Control Systems.    We provide full electrical control systems or a subset of those systems (core
electrical components) to manufacturers of wind turbines designed by us. Our electrical control systems regulate voltage, control power flows and maximize wind turbine efficiency, among other functions. To date, we have shipped enough core
electrical components and complete electrical control systems to power more than 10,000 MW of wind power. We believe our electrical control systems represent approximately 10% of a wind turbines bill of materials, representing an addressable
market in excess of $3 billion annually in 2011.

Grid market overview

Until the early part of the previous decade, transmission grid investment in the United States experienced a prolonged decline caused by uncertainty regarding the ownership of and return on transmission
grid investments. This period of underinvestment resulted in an increasing number of grid disturbances and blackouts. A study conducted by researchers at Lawrence Berkeley National Laboratory found that electric power outages and blackouts cost the
United States approximately $80 billion annually. These events and statistics have prompted broad recognition worldwide of the need to modernize and enhance the security of power grids. An increasing number of nations, including China, South Korea
and the United States, are promoting the adoption of new smart grid technologies and programs to enhance grid capacity, efficiency and reliability.

Power grid operators worldwide face various challenges, including:



| |  |  | Stability.    Power grid operators are confronting power quality and stability issues arising from intermittent renewable
energy sources and from the capacity limitations of transmission and overhead distribution lines and underground cables.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Reliability.    Traditional transmission lines and cables often reach their reliable voltage limit well below their thermal
threshold. Driving more power through a power grid when some lines and cables are operating above their voltage stability limit at peak demand times causes either low voltage in the power grid (a brownout) or risk of a sudden, uncontrollable voltage
collapse (a blackout).
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Capacity.    The traditional way to increase power grid capacity without losing voltage stability is to install more
overhead power lines and underground cables. However, permitting new transmission and distribution lines can take 10 years or more due to various public policy issues, such as environmental, aesthetic and health concerns. In urban and metropolitan
areas, installing additional conventional underground copper cables is similarly challenging, since many existing underground corridors carrying power distribution cables are already filled to their physical capacity and cannot accommodate any
additional conventional cables. In addition, adding new conduits requires excavation to expand existing corridors or create new corridors, which are costly and disruptive undertakings.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Efficiency.    Most overhead lines and underground cables use traditional conductors such as copper and aluminum, which lose
power due to electrical resistance. At transmission voltage, electrical losses average about 7% in the United States and other developed nations, but can exceed 20% in some locations due to the distance of the line and the power grids
architecture and characteristics, among other factors.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Our solutions for the grid market

We address these challenges in the Grid market by providing services and solutions designed to increase the power
grids capacity, reliability, security and efficiency.



| |  |  | Transmission Planning Services.We provide transmission planning services that identify power grid constraints and
determine how our solutions might improve network performance. These services often lead to sales of grid interconnection solutions for wind farms and solar power plants, power quality systems and transmission and distribution cable systems.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | D-VAR®Systems.    The power that flows through alternating current (AC) networks comprises both real power, measured in watts, and reactive power, measured in Volt Amp Reactives (VARs). In simple terms,
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| | reactive power is required to support voltage in the power network.
D-VAR® systems can provide the reactive power needed to stabilize voltage on the grid. These systems also can be
used to connect wind farms and solar power plants to the power grid seamlessly. Global Industry Analysts estimates that the global market for Flexible AC Transmission Systems (FACTS) such as D-VAR® was $1.5 billion in 2009.
| | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Superconductor Wire.    Conventional conductors of electricity, such as aluminum and copper wire, lose energy due to
resistance. Using a compound of yttrium barium copper oxide (YBCO), we manufacture and provide superconductor wire that can conduct many times more electricity than conventional conductors with no power loss. This wire can be
incorporated into a variety of applications, including motors, generators, fault current limiters and, most importantly, power cables.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Power Cables.    Underground cables, rather than overhead power lines, transmit an increasing amount of the worlds
power, particularly in urban and metropolitan areas. As power demands grow, grid capacity and reliability issues can arise. With their ability to carry up to ten times more power than conventional power cables, superconductor cables can effectively
break this bottleneck. We offer cable systems that are manufactured by third parties and also offer turnkey project management services to electric utilities. We believe the market for medium, high and extra-high voltage power cables exceeds $5
billion annually.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Core Technologies

Superconductors

Our second generation (2G)
high-temperature (HTS) wire technology helps us address the smart grid infrastructure market opportunity by providing components and solutions designed to increase the power grids capacity, reliability, security and efficiency. Our
wire, known as Amperium wire, conducts electricity with zero resistance below about -297 degrees Fahrenheit. The technology can be used in many applications including electricity transmission cables, superconducting generators, voltage
regulators and degaussing systems for naval vessels. Superconductor power cables, which are a class of high-capacity, environmentally-benign and easy-to-install transmission and distribution cables, address power grid capacity issues by increasing
the thermal limit of existing or new corridors. Superconductor power cables are cylindrically shaped systems consisting of HTS wires (which conduct electricity) surrounded by electrical insulation encased in a metal or polymeric jacket.

Currently, power cables are made primarily using copper wires. Power cables incorporating our Amperium wire are able to carry up to
ten times the electrical current of copper cables of the same diameter. These new cable systems also bring efficiency advantages. Traditional cable systems heat up due to the electrical resistance of copper, causing electrical losses. Electrical
losses at transmission voltage average about 7% in the United States and other developed nations, but can exceed 20% in some locations due to the distance of the line and the power grids architecture and characteristics, among other factors.
Conversely, HTS materials can carry direct current (DC) with 100% efficiency and alternating current (AC) with nearly 100% efficiency when they are cooled below a critical temperature. As a result, AC HTS power cables lose
significantly less power to resistive heating than copper cables, and DC HTS power cables have no energy losses due to resistive heating.

PowerModule Power Converters

Our family of
PowerModuleTMpower electronic converters incorporates
power semiconductor devices that switch, control and move large amounts of power faster and with far less disruption than the electromechanical switches historically used. While our family of PowerModule systems today are used primarily in
wind and power grid applications, they also have been incorporated into electric motor drives, distributed and dispersed generation devices (micro-turbines, fuel cells and PVs), power quality solutions, batteries and flywheel-based uninterruptible
power supplies.

Our wind turbine electrical control systems and our D-VAR® systems incorporate our PowerModule technology.

date on those contracts and purchase orders. Of our $291.5 million in backlog as of March 31, 2012, approximately 34% is scheduled for shipment to our customers during fiscal 2012 based on contractually agreed-upon terms.

Competition

We face
competition in various aspects of our technology and product development. We believe that competitive performance in the marketplace depends upon several factors, including technical innovation, range of products and services, product quality and
reliability, customer service and technical support.

##### Table of Contents

Wind

We face competition for the supply of wind turbine engineering design services from design engineering firms such as GL Garrad Hassan, and from licensors of wind turbine systems such as Aerodyn,
AventisEnergy and Fuhrlander.

We face competition from companies offering power electronic converters for use in applications
for which we expect to sell our PowerModule products. These companies include ABB, Semikron, Vacon and Xantrex (a subsidiary of Schneider Electric).

We face competition from companies offering various types of wind turbine electrical system components, which include ABB, Converteam, Guotong Electric, Ingeteam, Mita-Teknik, Woodward and Xantrex. We
also face indirect competition in the wind energy market from global manufacturers of wind energy systems, such as Gamesa, General Electric, Suzlon and Vestas.

Grid

We face competition from other companies
offering FACTS systems similar to our D-VAR® and Static Var Compensator, (SVC) solutions. These
include SVCs from ABB, Alstrom, AREVA, Mitsubishi Electric and Siemens; adaptive VAR compensators and STATCOMs produced by S&C Electric; DVRs produced by companies such as ABB and S&C Electric; and flywheels and battery-based UPS systems
offered by various companies around the world.

We face competition both from vendors of traditional wires made from materials
such as copper and from companies who are developing HTS wires. We also face competition for our Amperium wire from a number of companies in the United States and abroad who are developing 2G HTS wire technology. These include Innova, MetOx,
Superconductor Technologies and Superpower (a subsidiary of Furukawa) in the United States; Fujikura, Showa and Sumitomo in Japan; SuNAM in South Korea; and Bruker, evico GmbH and Nexans in Europe. Certain companies, including evico GmbH, Nexans,
Showa and Sumitomo Electric, have been focusing their research programs more recently on the development of 2G HTS wire made by the same or similar processes we have chosen to use to manufacture our Amperium wire.

Many of our competitors have substantially greater financial resources, research and development, manufacturing and marketing capabilities
than we do. In addition, as our target markets develop, other large industrial companies may enter these fields and compete with us.

Patents, licenses and trade secrets

Patent Background

An important part of our business strategy is to
develop a strong worldwide patent position in all of our technology areas. Our intellectual property (IP) portfolio includes both patents we own and patents we license from others. We devote substantial resources to building a strong
patent position, and we believe that we have significantly strengthened our position in the past several years. As of March 31, 2012, we owned (either solely or jointly) more than 125 U.S. patents and more than 30 U.S. patent applications on
file. We also hold licenses from third parties covering more than 100 issued U.S. patents and patent applications. Together with the international counterparts of each of these patents and patent applications, we own more than 600 patents and patent
applications worldwide, and have rights through exclusive and non-exclusive licenses to more than 270 additional patents and patent applications. We believe that our current patent position, together with our expected ability to obtain licenses from
other parties to the extent necessary, will provide us with sufficient proprietary rights to develop and sell our products. However, for the reasons described below, we cannot assure you that this will be the case.

Despite the strength of our patent position, a number of U.S. and foreign patents and patent applications of third parties relate to our
current products, to products we are developing, or to technology we are now using in the development or production of our products. We may need to acquire licenses to those patents, contest the scope or validity of those patents, or design around
patented processes or applications as necessary. If companies



7



---

##### Table of Contents

holding patents or patent applications that we need to license are competitors, we believe the strength of our patent portfolio will significantly improve our ability to enter into license or
cross-license arrangements with these companies. We have already successfully negotiated cross-licenses with several competitors. We may be required to obtain licenses to some patents and patent applications held by companies or other institutions,
such as national laboratories or universities, not directly competing with us. Those organizations may not be interested in cross-licensing or, if willing to grant licenses, may charge unreasonable royalties. We have successfully obtained licenses
related to HTS wire from a number of such organizations with royalties we consider reasonable. Based on historical experience, we expect that we will be able to obtain other necessary licenses on commercially reasonable terms. However, we cannot
assure you that we will be able to obtain all necessary licenses from competitors on commercially reasonable terms, or at all.

Failure to obtain all necessary patents, licenses and other IP rights upon reasonable terms could significantly reduce the scope of our
business and have a material adverse effect on our results of operations. We do not now know the likelihood of successfully contesting the scope or validity of patents held by others. In any event, we could incur substantial costs in challenging the
patents of other companies. Moreover, third parties could challenge some of our patents or patent applications, and we could incur substantial costs in defending the scope and validity of our own patents or patent applications whether or not a
challenge is ultimately successful.

There are no patents that we own or license expiring during fiscal 2012 that we consider
material to our business or competitiveness.

Wind and Grid Patents

We have received patents and filed a significant number of additional patent applications on power quality and
reliability systems, including our D-VAR® system. Our products are covered by more than 100 patents and patents
pending worldwide on both our systems and power converter products. The patents and applications focus on inventions that significantly improve product performance and reduce product costs, thereby providing a competitive advantage. One invention of
note allows for a reduction in the number of power inverters required in the system by optimally running the inverters in overload mode, thereby significantly reducing overall system costs. Another important invention uses inverters to offset
transients due to capacitor bank switching, which provides improved system performance.

Under our Windtec Solutions brand, we
design a variety of wind turbine systems and license these designs, including expertise and patent rights, to third parties for an upfront fee. Our wind turbine designs are covered by more than 100 patents and patents pending worldwide on wind
turbine technology. We have patent coverage on the unique design features of our blade pitch control system, which ensures optimal aerodynamic flow conditions on the turbine blades and improves system efficiency and performance. The pitch system
includes a patented SafetyLOCK feature that causes the blades to rotate to a feathered position to prevent the rotor blades from spinning during a fault.

We recognize the importance of IP protection in China and believe that China is steadily moving toward recognizing and acting in accordance with international norms for IP. As such, we have incorporated
China in our patent strategy for all of our various products. Nevertheless, we recognize that the risk of IP piracy is still higher in China than in most other industrialized countries, and so we are careful to limit the technology we provide
through our product sales and other expansion plans in China. While we take the steps necessary to ensure the safety of our IP, we cannot assure you that these measures will be fully successful. For example, see Part I, Item 3, Legal
Proceedings, for more information regarding legal proceedings that we have initiated against Sinovel alleging the illegal use of our intellectual property.

HTS Patents

Since the discovery of high temperature superconductors
in 1986, rapid technical advances have characterized the HTS industry, which in turn have resulted in a large number of patents, including overlapping patents, relating to superconductivity. As a result, the patent situation in the field of HTS
technology and products is unusually complex. We have obtained licenses to patents and patent applications covering some HTS materials. AMSC has acquired exclusive rights (through 2017) to a fundamental U.S. patent (U.S. 8,060,169 B1)

##### Table of Contents

covering (2G) and similar (HTS) wire and applications. However, we may have to obtain additional licenses to HTS materials.

We are focusing on the production of our Amperium wire, and we intend to continue to maintain a leadership
position in 2G HTS wire through a combination of patents, licenses and proprietary expertise. In addition to our owned patents and patent applications in 2G HTS wire, we have obtained licenses from (i) MIT for the MOD process we use to deposit
the YBCO layer, Alcatel-Lucent on the YBCO material, and (ii) the University of Tennessee/Battelle for the
RABiTS® process we use for the substrate and buffer layers for this technology. If alternative processes become
more promising in the future, we will also seek to develop a proprietary position in these alternative processes.

We have a
significant number of patents and patents pending covering applications of HTS wire, such as HTS fault current limiters, FaultBlocker technology (including both HTS power cables and fault current limiting capability) and HTS rotating machines.
Since the superconductor rotating machine and FaultBlocker applications are relatively new, we are building a particularly strong patent position in these areas. At present, we believe we have the worlds broadest and most fundamental
patent position in superconductor rotating machines technology. We have also filed a series of patents on our concept for our proprietary FaultBlocker technology. However, there can be no assurance that that these patents will be sufficient to
assure our freedom of action in these fields without further licensing from others. See Part I, Item 1A, Risk Factors, for more information regarding the status of the commercialization of our Amperium wire products.

Trade Secrets

Some of the important technology used in our operations and products is not covered by any patent or patent application owned by or licensed to us. However, we take steps to maintain the confidentiality
of this technology by requiring all employees and all consultants to sign confidentiality agreements and by limiting access to confidential information. We cannot assure you that these measures will prevent the unauthorized disclosure or use of that
information. For example, see Part I, Item 3, Legal Proceedings, for more information regarding legal proceedings that we have initiated against Sinovel alleging the illegal use of our intellectual property. In addition, we cannot
assure you that others, including our competitors, will not independently develop the same or comparable technology that is one of our trade secrets.

Employees

As of March 31, 2012, we employed 446 persons, 21 of whom
have a Ph.D. in materials science, physics or other fields. None of our employees is represented by a labor union. Retaining our key employees is important for achieving our goals, and we are committed to developing a working environment that
motivates and rewards our employees.

In August 2011, we initiated a restructuring plan to reorganize global operations,
streamline various functions of the business, and reduce our global workforce to match the demand for our products. A further restructuring action was undertaken in November 2011. From April 1, 2011 through March 31, 2012, we have reduced
our global workforce by approximately 50%, which is expected to result in annual savings of approximately $50 million.

|------------ | -------

Risks Related
to Our Operations

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

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

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

Although we have generally reported significant backlog, we cannot assure you that we will realize the revenue we expect to generate from
this backlog in the periods we expect to realize such revenue, or at all. For example, on March 31, 2011, Sinovel refused to accept contracted shipments of 1.5 MW and 3 MW wind turbine core electrical components and spare parts that we were
prepared to deliver. We have outstanding payments due from Sinovel for products and services delivered, not including value added taxes, of $62.0 million which have not yet been reported as revenue or accounts receivable. We have initiated
arbitration and civil proceedings against Sinovel and we have submitted evidence of criminal acts by Sinovel to the Chinese authorities in order to initiate criminal proceedings. As a result, Sinovel may not accept any further shipments or pay for
any past shipments. For more information about these legal proceedings, see Part I, Item 3, Legal Proceedings.

In addition, the backlog of orders, if realized, may not result in profitable revenue. Backlog represents the value of contracts and
purchase orders received, less the revenue recognized to date on those contracts and purchase orders. Our customers have the right under some circumstances and with some penalties or consequences to terminate, reduce or defer firm orders that we
have in backlog. In addition, our government contracts are subject to the risks described below. If our customers terminate, reduce or defer firm orders, we may be protected from certain costs and losses, but our sales will nevertheless be adversely
affected and we may not generate the revenue we expect.

Although we strive to maintain ongoing relationships with our
customers, there is an ongoing risk that they may cancel orders or reschedule orders due to fluctuations in their business needs or purchasing budgets.

Our business and operations would be adversely impacted in the event of a failure or security breach of our information technology infrastructure.

We rely upon the capacity, reliability, and security of our information technology hardware and software infrastructure and our ability to
expand and update this infrastructure in response to our changing needs. We are constantly updating our information technology infrastructure. Any failure to manage, expand, and update our information technology infrastructure or any failure in the
operation of this infrastructure could harm our business.

Despite our implementation of security measures, our systems are
vulnerable to damages from computer viruses, natural disasters, unauthorized access, and other similar disruptions. Our business is also subject to break-ins, sabotage, and intentional acts of vandalism by third parties as well as employees. Our
significant business activities in China may increase our risks to such breaches. For example, a former employee of our Austrian subsidiary pled guilty in September 2011 to charges of economic espionage and fraudulent manipulation of data. The
evidence presented during the trial 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. Moreover, the evidence shows that 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. Any system failure, accident, or security breach could result in disruptions to our operations. To the extent that any disruption or security
breach results in a loss or damage to our data, or inappropriate disclosure of confidential information, it could harm our business. In addition, we may be required to incur significant costs to protect against damage caused by these disruptions or
security breaches in the future.

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

We have attracted a highly skilled
management team and specialized workforce, including scientists, engineers, researchers, manufacturing, marketing and sales professionals. If we were to lose the services of any of our executive officers or key employees, our business could be
materially and adversely impacted.

Hiring and retaining good personnel for our business is challenging, and highly qualified
technical personnel are likely to remain a limited resource for the foreseeable future despite current economic conditions and high unemployment levels. We may not be able to hire the necessary personnel to implement our business strategy, or we may
need to provide higher compensation or more training to our personnel than we currently anticipate. Moreover, any officer or employee can terminate his or her relationship with us at any time.

During fiscal 2011, we reduced our global workforce by approximately 50% in order to lower expenses, reorganize our global operations, and
streamline various functions of the business, to match the demand for our products. Employee retention may be a particularly challenging issue following reductions in workforce and organizational changes since we also must continue to motivate
employees and keep them focused on our strategies and goals. If we lose the services of any key personnel, our business, results of operations and financial condition could be materially adversely affected.

We rely upon third-party suppliers for the components and subassemblies of many of our Wind and Grid products, making us vulnerable
to supply shortages and price fluctuations, which could harm our business.

Many of our components and subassemblies
are currently manufactured for us by a limited number of qualified suppliers. Any interruption in the supply of components or subassemblies, or our inability to obtain substitute components or subassemblies from alternate sources at acceptable
prices in a timely manner, could impair our ability to meet the demand of our customers, which would have an adverse effect on our business and operating results.

We are producing certain Wind products in our manufacturing facility in China. In order to minimize costs and time to market, we have and will continue to identify local suppliers that meet our quality
standards to produce certain of our subassemblies and components. These efforts may not be successful. In addition, any event which negatively impacts our supply, including, among others, wars, terrorist activities, natural disasters and outbreaks
of infectious disease, could delay or suspend shipments of products or the release of new products or could result in the delivery of inferior products. Our revenues from the affected products would decline or we could incur losses until such time
as we are able to restore our production processes or put in place alternative contract manufacturers or suppliers. Even though we carry business interruption insurance policies, we may suffer losses as a result of business interruptions that exceed
the coverage available under our insurance policies.

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

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

If we fail to implement our business strategy successfully, our financial performance
could be harmed.

Our future financial performance and success are dependent in large part upon our ability to
implement our business strategy successfully. Our business strategy envisions several initiatives, including driving revenue growth and enhancing operating results by increasing customer adoption of our products by targeting high-growth segments
with commercial products, pursuing overseas markets, anticipating customer needs in the development of system-level solutions, strengthening our technology leadership while lowering cost and pursuing targeted strategic alliances. We may not be able
to implement our business strategy successfully or achieve the anticipated benefits of our business plan. If we are unable to do so, our long-term growth and profitability may be adversely affected. Even if we are able to implement some or all of
the initiatives of our business plan successfully, our operating results may not improve to the extent we anticipate, or at all. In addition, to the extent we have misjudged the nature and extent of industry trends or our competition; we may have
difficulty in achieving our strategic objectives. Any failure to implement our business strategy successfully may adversely affect our business, financial condition and results of operations. In addition, we may decide to alter or discontinue
certain aspects of our business strategy at any time.

This risk is magnified by the current substantial uncertainty in our
business, particularly as it relates to the ongoing arbitration and civil proceedings with Sinovel and our ability to raise additional funds all of which is diverting managements attention from operating our business. Management has and is
continuing to invest considerable time addressing these issues, which has been a substantial diversion of managements attention and could lead to disruptions in operations and delay in the implementation of our strategy, all of which could
negatively impact our business and results of operations.

Our ability to address the disruption in our relationship with
Sinovel or implement our business strategy could also be affected by a number of factors beyond our control, such as increased competition, legal developments, government regulation, general economic conditions or increased operating costs or
expenses.

Problems with product quality or product performance may cause us to incur warranty expenses and may damage
our market reputation and prevent us from achieving increased sales and market share.

Consistent with customary
practice in our industry, we warrant our products and/or services to be free from defects in material and workmanship under normal use and service. We generally provide a one- to three-year warranty on our products, commencing upon installation. A
provision is recorded upon revenue recognition to cost of revenues for estimated warranty expense based on historical experience. The possibility of future product failures or issues related to services we provided could cause us to incur
substantial expenses to repair or replace defective products or re-perform such services. Furthermore, widespread product failures may damage our market reputation and reduce our market share and cause sales to decline.

Our contracts with the U.S. government are subject to audit, modification or termination by the U.S. government and include certain
other provisions in favor of the government. The continued funding of such contracts remains subject to annual congressional appropriation which, if not approved, could reduce our revenue and lower or eliminate our profit.

As a company that contracts with the U.S. government, we are subject to financial audits and other reviews by the U.S. government of our
costs and performance, accounting and general business practices relating to these contracts. Based on the results of these audits, the U.S. government may adjust our contract-related costs and fees. We cannot be certain that adjustments arising
from government audits and reviews would not have a material adverse effect on our results of operations.

Our U.S. government
contracts customarily contain other provisions that give the government substantial rights and remedies, many of which are not typically found in commercial contracts, including provisions that allow the government to:



| |  |  | obtain certain rights to the intellectual property that we develop under the contract;
| | - |  | --------------------------------------------------------------------------------------



| |  |  | decline to award future contracts if actual or apparent organizational conflicts of interest are discovered, or to impose organizational conflict
mitigation measures as a condition of eligibility for an award;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| |  |  | suspend or debar us from doing business with the government or a specific government agency; and
| | - |  | ------------------------------------------------------------------------------------------------



| |  |  | pursue criminal or civil remedies under the False Claims Act, False Statements Act and similar remedy provisions unique to government contracting.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------

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

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

Our prior acquisitions required substantial integration and management efforts. As a result of any acquisition we pursue, managements attention and resources may be diverted from our other
businesses. An acquisition may also involve the payment of a significant purchase price, which could reduce our cash position or dilute our stockholders, and require significant transaction-related expenses.

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



| |  |  | difficulty assimilating acquired operations, technologies and personnel;
| | - |  | ------------------------------------------------------------------------



| |  |  | inability to retain management and other key personnel of the acquired business;
| | - |  | --------------------------------------------------------------------------------



| |  |  | changes in management or other key personnel that may harm relationships with the acquired businesss customers and employees;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------



| |  |  | unforeseen liabilities of the acquired business;
| | - |  | ------------------------------------------------



| |  |  | diversion of managements and employees attention from other business matters as a result of the integration process;
| | - |  | ----------------------------------------------------------------------------------------------------------------------



| |  |  | mistaken assumptions about volumes, revenue and costs, including synergies;
| | - |  | ---------------------------------------------------------------------------



| |  |  | limitations on rights to indemnity from the seller;
| | - |  | ---------------------------------------------------



| |  |  | mistaken assumptions about the overall costs of equity or debt used to finance the acquisition; and
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | unforeseen difficulties operating in new product areas, with new customers, or in new geographic areas.
| | - |  | -------------------------------------------------------------------------------------------------------

We cannot assure you that we will realize any of the anticipated benefits of any acquisition, and if we fail to realize these anticipated
benefits, our operating performance could suffer.

Many of our customers outside of the United States are, either
directly or indirectly, related to governmental entities, and we could be adversely affected by violations of the United States Foreign Corrupt Practices Act and similar worldwide anti-bribery laws outside the United States.

The U.S. Foreign Corrupt Practices Act and similar worldwide anti-bribery laws in non-U.S. jurisdictions generally prohibit companies and
their intermediaries from making improper payments to non-U.S. officials for the purpose of obtaining or retaining business. Many of our customers outside of the United States are, either directly or indirectly, related to governmental entities and
are therefore subject to such anti-bribery laws. Our policies mandate compliance with these anti-bribery laws. We operate in many parts of the world that have



14

##### Table of Contents

experienced governmental corruption to some degree, and in certain circumstances strict compliance with anti-bribery laws may conflict with local customs and practices. Our internal control
policies and procedures may not always protect us from reckless or criminal acts committed by our employees or agents. Violations of these laws, or allegations of such violations, could disrupt our business and result in a material adverse effect on
our business, results of operations and financial condition.

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

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

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

Risks Related to Our Financial performance

We have a history of operating losses, and we may incur additional losses in the future. Our operating results may fluctuate
significantly from quarter to quarter and may fall below expectations in any particular fiscal quarter.

While we
achieved profitable results in fiscal 2009, we recorded a net loss in fiscal 2010 and fiscal 2011, and we are unlikely to be profitable in fiscal 2012. We cannot be certain that we will regain profitability in the future. We incurred net losses in
each year since our inception through fiscal 2008, driven primarily by the research and development activities in what was formerly our AMSC Superconductors business segment.

There is currently substantial uncertainty in our business, particularly given the disruption to our relationship with Sinovel and the associated loss of revenue, which makes it difficult to evaluate our
business and future prospects. In addition, our operating results historically have been difficult to predict and have at times fluctuated from quarter to quarter due to a variety of factors, many of which are outside of our control. As a result of
all of these factors, comparing our operating results on a period-to-period basis may not be meaningful, and you should not rely on our past results as an indication of our future performance. If our revenue or operating results fall below the
expectations of investors or any securities analysts that follow our company in any period, the trading price of our common stock would likely decline.

Our operating expenses do not always vary directly with revenue and may be difficult to adjust in the short term. As a result, if revenue for a particular quarter is below our expectations, we may not be
able to proportionately reduce operating expenses for that quarter, and therefore such a revenue shortfall would have a disproportionate effect on our operating results for that quarter.

We may require additional funding in the future and may be unable to raise capital when needed.

As of March 31, 2012, we had approximately $66.2 million of cash, cash equivalents, marketable securities and restricted cash. We
have experienced a substantial decline in revenues and incurred a net loss of $136.8 million for the fiscal year ended March 31, 2012. At March 31, 2012, we had accrued liabilities related to adverse purchase commitments for inventory
totaling $25.9 million. During fiscal 2011, we reduced our global workforce by approximately 50%, which is expected to result in annual savings of approximately $50 million. Our cost reduction efforts and anticipated revenue growth are expected to
result in a substantial reduction in cash

##### Table of Contents

used for operations during the fiscal year ended March 31, 2013. We plan to continue to closely monitor our expenses and if required, will further reduce operating costs and capital spending
to enhance liquidity. We are working with our inventory suppliers to delay cash settlements and reduce the gross liability associated with our adverse purchase commitments. During the quarter ending June 30, 2012, we completed a private
placement of $25 million of 7% senior convertible notes and a $10 million senior secured term loan. See Item 8. Financial Statements and Supplementary DataNote 18, Subsequent Events of our consolidated financial
statements for further information regarding these new debt obligations. We may seek additional financing; however, there can be no assurance that financing will be available on commercially acceptable terms or at all. Moreover, our new 7% senior
convertible note in particular restricts our ability to obtain additional financing. Our liquidity is highly dependent on our ability to profitably grow our revenues, successfully manage our adverse purchase commitments, fund monthly obligations on
the convertible notes and raise additional capital as required.

Our new debt obligations include certain covenants and
other events of default. Should we not comply with the covenants or incur an event of default, we may be required to repay our debt obligations in cash, which could have an adverse effect on our liquidity.

During the quarter ending June 30, 2012, we sold $25 million of 7% convertible notes and entered into a $10 million senior secured
term loan. See Item 8. Financial Statements and Supplementary Data  Note 18, Subsequent Events of our consolidated financial statements for further information regarding these new debt obligations. These new debt obligations
include certain financial and administrative covenants, including a requirement in the term loan to maintain a minimum unrestricted U.S. cash balance equal to the outstanding principal of the loan. There are other events of default in the new debt
obligations, including with respect to the convertible notes the suspension from trading or the failure of our common stock to be traded or listed on certain defined markets and the rendering of certain uninsured judgments against us, as well as
cross defaults between the convertible note and the term loan.

If we fail to stay in compliance with our covenants or suffer
some other event of default of either the convertible note or the term loan, we may be required to repay the outstanding principal 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 impacted.

We have recorded a liability for adverse purchase commitments with certain of our vendors. Should we be required to settle these liabilities in cash, our liquidity could be adversely affected.

As of March 31, 2012, we have recorded a liability for $25.9 million in adverse purchase commitments. These
purchase commitments are for the purchase of inventory associated with Sinovel for which there is little or no further demand. We are currently working with our suppliers to satisfy these liabilities in a manner and timing that does not jeopardize
our long-term liquidity. During the quarter ending June 30, 2012, we settled several adverse purchase commitment liabilities with certain vendors. In conjunction with the settlements, we agreed to provide certain of our vendors with letters of
credit and bank guarantees 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. Should our other suppliers demand immediate payment
against these liabilities in cash or require security in the form of cash collateralized letter of credits, our liquidity could be adversely affected. Conversely, should our vendors accept payment from us in shares of our common stock, our liquidity
would not be adversely impacted; however your ownership in our company would be diluted.

If we fail to maintain proper
and effective internal controls over financial reporting, our ability to produce accurate and timely financial statements could be impaired and may lead investors and other users to lose confidence in our financial data.

Maintaining effective internal controls over financial reporting is necessary for us to produce reliable financial statements. In
connection with the preparation of our financial statements for the fiscal year ended March 31, 2011, our management and our independent registered public accounting firm identified certain material weaknesses in our internal controls, which we
remediated during the fourth quarter of the fiscal year ended March 31, 2012. While our management and our independent registered public accounting firm concluded



16



---

##### Table of Contents

that our internal control over financial reporting was effective as of March 31, 2012, it is possible that material weaknesses may be identified in the future.

We note that a system of procedures and controls, no matter how well conceived and operated, can provide only reasonable, not absolute,
assurance that the objectives of the control system are met. Because of the inherent limitations in all systems of procedures and controls, no evaluation can provide absolute assurance that all control issues, including instances of fraud, if any,
have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and breakdowns can occur because of simple errors or mistakes. Additionally, procedures and controls can be circumvented by the
individual acts of some persons, by collusion of two or more people, or by management override. The design of any system of procedures and controls also is based in part upon certain assumptions about the likelihood of future events, and there can
be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, our systems of procedures and controls, as we further develop and enhance them, may become inadequate because of changes in
conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective system of procedures and controls, misstatements due to errors or fraud may occur and not be detected.
Such misstatements could be material and require a restatement of our financial statements.

If we are unable to maintain
effective internal controls, we may not have adequate, accurate or timely financial information, and we may be unable to meet our reporting obligations or comply with the requirements of the SEC or the Sarbanes-Oxley Act of 2002, which could result
in the imposition of sanctions, including the inability of registered broker dealers to make a market in our common stock, or investigation by regulatory authorities. Any such action or other negative results caused by our inability to meet our
reporting requirements or comply with legal and regulatory requirements or by disclosure of an accounting, reporting or control issue could adversely affect the trading price of our securities and our business. Significant deficiencies or material
weaknesses in our internal control over financial reporting could also reduce our ability to obtain financing or could increase the cost of any financing we obtain.

We may be required to issue performance bonds or provide letters of credit, which restricts our ability to access any cash used as collateral for the bonds or letters of credit.

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

Changes in exchange rates could adversely affect our results from operations.

Currency exchange rate fluctuations could have an adverse effect on our revenues and results of operations, and we could experience losses
with respect to hedging activities. In fiscal 2011, 72% of our revenues were recognized from sales outside the United States. Unfavorable currency fluctuations could require us to increase prices to foreign customers, which could result in lower
revenues from such customers. Alternatively, if we do not adjust the prices for our products in response to unfavorable currency fluctuations, our results of operations could be adversely affected. In addition, most sales made by our foreign
subsidiaries are denominated in the currency of the country in which these products are sold, and the currency they receive in payment for such sales could be less valuable at the time of receipt as a result of exchange rate fluctuations. From time
to time, we enter into derivative instruments, including forward foreign exchange contracts and currency options to reduce currency exposure arising from intercompany sales of inventory and exposures arising from the sale of products denominated in
one currency while costs are denominated in another. However, we cannot be certain that our efforts will be adequate to protect us against significant currency fluctuations or that such efforts will not expose us to additional exchange rate risks.

Risks Related to Our Markets

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

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

We depend on sales to
customers in China, and global conditions could negatively affect our operating results or limit our ability to expand our operations outside of China. Changes in Chinas political, social, regulatory and economic environment may affect our
financial performance.

A significant portion of our total revenues has been derived from customers in China. With
respect to China, our financial performance may be affected by changes in Chinas political, social, regulatory and economic environment. For example, new grid interconnection standards are being imposed in China, which has slowed the wind
turbine installation growth rate at least temporarily. Such changes mean the Chinese wind market will be subject to substantial uncertainty, which may cause our customers to delay or cancel orders.

The role of the Chinese central and local governments in the Chinese economy is significant. For example, the economy of the Peoples
Republic of China differs from the economies of most developed countries in many respects, including the:



| |  |  | higher level of government involvement;
| | - |  | ---------------------------------------



| |  |  | early stage of development of the market-oriented sector of the economy;
| | - |  | ------------------------------------------------------------------------



| |  |  | rapid growth rate;
| | - |  | ------------------



| |  |  | higher level of control over foreign exchange; and
| | - |  | --------------------------------------------------



| |  |  | government influence over the allocation of resources.
| | - |  | ------------------------------------------------------

Chinese policies toward economic liberalization, and laws and policies affecting foreign companies, currency exchange rates and other matters could change, resulting in greater restrictions on our ability
to do business in China. Any imposition of surcharges or any increase in Chinese tax rates could hurt our operating results. The Chinese government could revoke, terminate or suspend our license for national security and similar reasons without
compensation to us. If the government of China were to take any of these actions, we would be prevented from conducting all or part of our business. Any failure on our part to comply with governmental regulations could result in the loss of our
ability to market our products in China.

Further, we may be impacted by issues with managing foreign sales operations,
including long payment cycles, potential difficulties in accounts receivable collection and, especially from significant customers, fluctuations in the timing and amount of orders and the adverse effect of any of these issues on our business could
be increased due to the concentration of our business with a small number of customers. The Chinese government has in the past restricted lending from banks to companies in China as a means to fight inflation, resulting in a limitation of access to
credit. In addition, we believe that many of our customers in China have high levels of inventory and high accounts payable balances. Problems with collections from, or sales to, any one of those customers could reduce our revenue and harm our
financial performance. Operations in foreign countries

including China also expose us to risks relating to difficulties in enforcing our proprietary rights, currency fluctuations and adverse or deteriorating economic conditions. If we experience
problems with obtaining registrations, compliance with foreign country or applicable U.S. laws, or if we experience difficulties in payments or intellectual property matters in foreign jurisdictions, or if significant political, economic or
regulatory changes occur, our results of operations would be adversely affected.

Our products face intense competition,
which could limit our ability to acquire or retain customers.

The markets for our products are intensely competitive
and many of our competitors have substantially greater financial resources, research and development, manufacturing and marketing capabilities than we do. In addition, as our target markets develop, other large industrial companies may enter these
fields and compete with us.

Our Wind business faces competition for the supply of wind turbine engineering design services
from design engineering firms such as GL Garrad Hassan, and from licensors of wind turbine systems such as Aerodyn, AventisEnergy and Fuhrlander.

Our Wind business also faces competition from companies offering power electronic converters for use in applications for which we expect to sell our PowerModule products. These companies include ABB,
Semikron, Vacon and Xantrex (a subsidiary of Schneider Electric).

Finally, our Wind business faces competition from companies
offering wind turbine electrical system components, including ABB, Converteam, Guotong Electric, Ingeteam, Mita-Teknik, Woodward and Xantrex. We also face indirect competition in the wind energy market from global manufacturers of wind energy
systems, such as Gamesa, General Electric, Suzlon and Vestas.

Our Grid business faces competition from companies offering
FACTS systems similar to our D-VAR and SVC solutions. These include SVCs from ABB, Alstrom, AREVA, Mitsubishi Electric and Siemens; adaptive VAR compensators and STATCOMs produced by S&C Electric; dynamic voltage restorers (DVRs)
produced by companies such as ABB and S&C Electric; and flywheels and battery-based UPS systems offered by various companies around the world.

Our Grid business also faces competition both from vendors of traditional wires made from materials such as copper and from companies who are developing HTS wires.

Finally, our Grid business faces competition for our Amperium wire from a number of companies in the United States and abroad who are
developing 2G HTS wire technology. These include Innova, MetOx, Superconductor Technologies and Superpower (a subsidiary of Furukawa) in the United States; Fujikura, Showa and Sumitomo in Japan; SuNAM in South Korea; and Bruker, evico GmbH and
Nexans in Europe. Certain companies, including evico GmbH, Nexans, Showa and Sumitomo Electric, have been focusing their research programs more recently on the development of 2G HTS wire made by the same or similar processes we have chosen to use to
manufacture our Amperium wire.

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

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

In recent years, a substantial majority of our consolidated revenues were recognized from
customers outside of the United States. For example, 72% of our revenues in fiscal 2011 and 93% of our revenues in fiscal 2010 were recognized from sales outside the United States. Our international operations are subject to a variety of risks that
we do not face in the United States, including:



| |  |  | potentially longer payment cycles for sales in foreign countries and difficulties in collecting accounts receivable, particularly from customers in
China;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------



19



---

##### Table of Contents

| |  |  | difficulties in staffing and managing our foreign offices and the increased travel, infrastructure and legal compliance costs associated with multiple
international locations;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | additional withholding taxes or other taxes on our foreign income and repatriated cash, and tariffs or other restrictions on foreign trade or
investment, including export duties and quotas, trade and employment restrictions;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | imposition of, or unexpected adverse changes in, foreign laws or regulatory requirements;
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | increased exposure to foreign currency exchange rate risk;
| | - |  | ----------------------------------------------------------



| |  |  | reduced protection for intellectual property rights in some countries; and
| | - |  | --------------------------------------------------------------------------



| |  |  | political unrest, war or acts of terrorism.
| | - |  | -------------------------------------------

Our overall success in international markets depends, in part, upon our ability to succeed in differing legal, regulatory, economic, social and political conditions. We may not be successful in developing
and implementing policies and strategies that will be effective in managing these risks in each country where we do business or conduct operations. Our failure to manage these risks successfully could harm our international operations and reduce our
international sales, thus lowering our total revenue and reducing or eliminating our profits.

Adverse changes in
domestic and global economic conditions could adversely affect our operating results.

We have become increasingly
subject to the risks arising from adverse changes in domestic and global economic conditions. The state of both the domestic and global economies is uncertain due to the difficulty in obtaining credit, weak economic recovery, and financial market
volatility. If credit continues to be difficult to obtain, some customers may delay or reduce purchases. This could result in reductions in sales of our products, longer sales cycles, slower adoption of new technologies, increased accounts
receivable and inventory write-offs and increased price competition. Any of these events would likely harm our business, results of operations and financial condition.

Risks Related to Our Technologies

We may be unable to adequately
prevent disclosure of trade secrets and other proprietary information.

We rely on trade secrets to protect our
proprietary technologies, especially where we do not believe patent protection is appropriate or obtainable. However, trade secrets are difficult to protect. We rely in part on confidentiality agreements with our employees, contractors, consultants,
outside scientific collaborators and other advisors to protect our trade secrets and other proprietary information. These agreements may not effectively prevent disclosure of confidential information and may not provide an adequate remedy in the
event of unauthorized disclosure of confidential information. In addition, others may independently discover our trade secrets or independently develop processes or products that are similar or identical to our trade secrets, and courts outside the
United States may be less willing to protect trade secrets. Costly and time-consuming litigation could be necessary to enforce and determine the scope of our proprietary rights, and failure to obtain or maintain trade secret protection could
adversely affect our competitive business position.

For example, 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 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. On September 13, 2011, we commenced a series of legal actions in China against Sinovel and other parties alleging the illegal use of our intellectual property. We cannot provide any assurance as
to the outcome of these legal actions. This or future litigation with Sinovel could result in substantial costs and divert managements attention and resources, which could have an adverse effect on our business, operating results and financial
condition. In addition, such proceedings may make it more difficult to finance our operations. If we are unsuccessful in this litigation and fail to maintain adequate protection of this intellectual property, our competitive business position would
be adversely affected. For more information about these legal proceedings, see Part I, Item 3, Legal Proceedings.

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

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



| |  |  | the patent applications that we or our licensors file may not result in patents being issued;
| | - |  | ---------------------------------------------------------------------------------------------



| |  |  | any patents issued may be challenged by third parties; and
| | - |  | ----------------------------------------------------------



| |  |  | others may independently develop similar technologies not protected by our patents or design around the patented aspects of any technologies we
develop.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------

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

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

To date, there has been no widespread commercial use of HTS products. Even if the technological hurdles
currently limiting commercial uses of HTS products are overcome, it is uncertain whether a robust commercial market for those new and unproven products will ever develop. To date, many projects to install superconductor cables and products in power
grids have been funded or subsidized by the governmental authorities. If this funding is curtailed, grid operators may not continue to use superconductor cables and products in their projects.

In addition, we believe in-grid demonstrations of superconductor power cables are necessary to convince utilities and power grid operators
of the benefits of this technology. Even if a project is funded, completion of projects can be delayed as a result of other factors.

It is possible that the market demands we currently anticipate for our Amperium products will not develop and that they will never achieve widespread commercial acceptance. In such event, we would not be
able to implement our strategy, and our profits could be reduced or eliminated.

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

Many of our superconductor products are in the early stages of commercialization, while others are still
under development. There are a number of technological challenges that we must successfully address to complete our development and commercialization efforts for superconductor products. We also believe that several years of further demonstration in
the cable, fault current limiter and motor industries may be necessary before a substantial commercial market could develop. We will also need to improve the performance and reduce the cost of our Amperium wire to expand the number of commercial
applications for it. We may be unable to meet such technological challenges or to sufficiently improve the performance and reduce the costs of our Amperium wire. Delays in development, as a result of technological challenges or other factors, may
result in the introduction or commercial acceptance of our superconductor products later than anticipated.

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

We are developing commercial-scale manufacturing processes for our Amperium wire, which are complex and challenging.
In November 2007, we started initial production of our Amperium wire on a new manufacturing line that was designed for an annual capacity of 720,000 meters. However, in order to be able to offer our wire at



21



---

##### Table of Contents

pricing that we believe will be commercially competitive, we estimate that we will need to increase such capacity to millions of meters annually. We may not be able to manufacture satisfactory
commercial quantities of Amperium wire of consistent quality with an acceptable yield and cost. Failure to successfully scale up manufacturing of our Amperium wire would result in a significant limitation of our ability to achieve broad market
acceptance of our HTS products and of our future revenue and profit potential.

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

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

Our technology and products could infringe intellectual property rights of others, which may require costly
litigation and, if we are not successful, could cause us to pay substantial damages and disrupt our business.

In
recent years, there has been significant litigation involving patents and other intellectual property rights in many technology-related industries. There may be patents or patent applications in the United States or other countries that are
pertinent to our products or business of which we are not aware. The technology that we incorporate into and use to develop and manufacture our current and future products, including the technologies we license, may be subject to claims that they
infringe the patents or proprietary rights of others. The success of our business will also depend on our ability to develop new technologies without infringing or misappropriating the proprietary rights of others. Third parties may allege that we
infringe patents, trademarks or copyrights, or that we misappropriated trade secrets. These allegations could result in significant costs and diversion of the attention of management. If a successful claim were brought against us and we are found to
infringe a third partys intellectual property rights, we could be required to pay substantial damages, including treble damages if it is determined that we have willfully infringed such rights, or be enjoined from using the technology deemed
to be infringing or using, making or selling products deemed to be infringing. If we have supplied infringing products or technology to third parties, we may be obligated to indemnify these third parties for damages they may be required to pay to
the patent holder and for any losses they may sustain as a result of the infringement. In addition, we may need to attempt to license the intellectual property right from such third party or spend time and money to design around or avoid the
intellectual property. Any such license may not be available on reasonable terms, or at all. An adverse determination may subject us to significant liabilities and/or disrupt our business.

Risks Related to Our Legal Matters

We have filed a demand for
arbitration and other lawsuits against our former largest customer, Sinovel, regarding amounts we contend are overdue. We cannot be certain as to the outcome of these proceedings.

On March 31, 2011, Sinovel refused to accept contracted scheduled shipments with a revenue value of approximately $65.2
million. In addition, as of March 31, 2011, we had approximately $62.0 million of receivables (excluding value added tax) outstanding from Sinovel. We have not received payment from Sinovel for these outstanding receivables that are now
past due, nor have we been notified as to when, if ever, they will accept contracted shipments that were scheduled for delivery after March 31, 2011. No payment has been received from Sinovel since early March 2011. Because Sinovel did not give
us notice that it intended to delay deliveries as required under the contracts, we believe that these actions constitute material breaches of our contracts. Additionally, we believe that Sinovel illegally obtained and used our intellectual property
in violation of civil and criminal intellectual property laws.



22

##### Table of Contents

On September 13, 2011, we filed a claim for arbitration against Sinovel 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. In addition, we have filed civil complaints in China
against Sinovel alleging the illegal use of our intellectual property. Sinovel has filed counterclaims against us with the Beijing Arbitration Commission for breach of the same contracts under which we filed our original arbitration claim. Sinovel
claims, among other things, that the goods supplied by us do not conform to the standards specified in the contracts and has claimed net damages in the amount of approximately RMB 1.2 billion ($190 million). As the legal proceedings continue,
we and Sinovel may identify additional amounts in dispute. We cannot provide any assurance as to the outcome of these legal actions or that, if we prevail, we ultimately will be able to collect any amounts awarded. Moreover, these legal proceedings
could result in the incurrence of significant legal and related expenses, which may not be recoverable depending on the outcome of the litigation. An award by the arbitration panel or court in favor of Sinovel and/or the incurrence of significant
legal fees that are not recoverable could adversely impact our operating results. For more information about these legal proceedings, see Part I, Item 3, Legal Proceedings.

We have been named as a party to purported stockholder class actions and stockholder derivative complaints, and we may be named in
additional litigation, all of which will require significant management time and attention, result in significant legal expenses and may result in an unfavorable outcome, which could have a material adverse effect on our business, operating results
and financial condition.

A number of purported class action lawsuits have been filed against us on behalf of certain
purchasers of our common stock. The complaints generally include allegations that we violated federal securities laws by, among other things, knowingly making materially false and misleading statements and omitting important facts regarding our
dealings with Sinovel, thereby artificially inflating the price of our common stock. The complaints seek monetary damages, costs, attorneys fees and other equitable and injunctive relief. Securities class action suits and derivative suits
are often brought against companies following periods of volatility in the market price of their securities. In addition, stockholder derivative actions have been initiated against us and certain of our directors and officers. These complaints
purport to seek relief on behalf of the company to remedy alleged breaches of fiduciary duty and other misconduct by the defendants.

We intend to defend these lawsuits vigorously. We cannot assure you, however, that we will be successful. Also, our insurance coverage may be insufficient, our assets may be insufficient to cover any
amounts that exceed our insurance coverage, and we may have to pay damage awards or otherwise may enter into settlement arrangements in connection with such claims. Any such payments or settlement arrangements in this current litigation or any
future litigation could have material adverse effects on our business, operating results or financial condition. Even if the plaintiffs claims are not successful, this or future litigation could result in substantial costs and significantly
and adversely impact our reputation and divert managements attention and resources, which could have a material adverse effect on our business, operating results or financial condition. In addition, such lawsuits may make it more difficult to
finance our operations.

Risks Related to Our Common Stock

Our 7% convertible note contains warrants and provisions that could limit our ability to repay the note in shares of common stock and should the note be repaid in stock, shareholders could
experience significant dilution

On April 4, 2012, we entered into a Securities Purchase Agreement with an
affiliate of Heights Capital whereby we sold an aggregate of $25 million of unsecured senior convertible notes and a warrant to purchase 3,094,060 shares of common stock at $5.45 per share. Additionally, subject to the satisfaction of certain
conditions, we have the right to require Heights to purchase an additional $15 million of unsecured senior convertible notes and a warrant to purchase additional shares of our common stock. The convertible notes contain a provision to allow us to
repay the notes in shares of our common stock based on a price per share that is 85% of the market price at the time of each payment, as defined, subject to certain price and volume conditions. Repayment of the notes in shares of common stock could
have an adverse effect on our stock price and would dilute your ownership of the company. Moreover, should the warrants be exercised, your ownership in our



23



---

##### Table of Contents

company will be further diluted. Our liquidity may be adversely affected should we not meet the price and volume conditions under the notes and are required to repay the notes in cash.

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

The market price of our common stock has historically experienced significant volatility and may continue to experience such volatility in
the future. Factors such as our financial performance, technological achievements by us and our competitors, the establishment of development or strategic relationships with other companies, strategic acquisitions, new customer orders and contracts,
our exposure to, and the disruption in our relationship with Sinovel, and our introduction of commercial products may have a significant effect on the market price of our common stock. For example, after we announced on April 5, 2011 that our
largest customer, Sinovel, had refused shipments on March 31, 2011, our stock price dropped significantly. In addition, the stock market in general, and the stock of high technology companies in particular, have in recent years experienced
extreme price and volume fluctuations, which are often unrelated to the performance or condition of particular companies. Such broad market fluctuations could adversely affect the market price of our common stock. Due to these factors, the price of
our common stock may decline and investors may be unable to resell their shares of our common stock for a profit. Following periods of volatility in the market price of a particular companys securities, securities class action litigation has
often been brought against that company. Currently a number of purported class action lawsuits have been filed against us on behalf of certain purchasers of our common stock, which we are prepared to rigorously defend. If we become subject to
additional litigation of this kind in the future, it could result in additional substantial litigation costs, a damages award against us and the further diversion of our managements attention.

We also occupy
leased facilities located in Middleton and New Berlin, Wisconsin; Suzhou and Beijing, China; and Klagenfurt, Austria with a combined total of approximately 299,000 square feet of space. These leases have varying expiration dates through February
2016 which can generally be terminated at our request after a six month advance notice. Our other locations focus primarily on applications engineering, sales and/or field service and do not have significant leases or physical presence. We believe

|Item 3.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. To date, the district court has not issued an order
regarding the Exchange Act claims against us and our officers or the Securities Act claims against the underwriters, so those matters remain under advisement.

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 captionedIn 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.

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 the 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.

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. We are currently
awaiting notice from the Beijing No. 1 Intermediate Peoples Court regarding the evidence submission deadline and 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, (2010) 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.

Included in the net loss for the fiscal year ended March 31, 2012 was stock-based compensation
expense of $9.9 million, a write-off of an advance payment to The Switch of $20.6 million, restructuring and impairment charges of $9.2 million, expense of patent costs of $4.9 million, and Sinovel legal expenses of $5.8 million. Net loss for the
fiscal year ended March 31, 2011 included $13.4 million in employee stock-based compensation expense. Also included in net loss for the fiscal year ended March 31, 2011 were charges primarily attributable to events surroundings our largest
customer, Sinovel, a manufacturer of wind energy systems in China, including an increase in the provision for excess and obsolete inventory of $63.9 million, loss on adverse purchase commitments of $38.8 million, impairment of goodwill and certain
other long-lived assets of $50.0 million and a write-off of prepaid value added taxes of $5.9 million. Sinovel refused to accept scheduled shipments on March 31, 2011. As a result of subsequent legal actions, we determined that the customer
relationship with Sinovel would no longer continue. This impacted the valuation of assets, including inventory and goodwill, as well as the accrual of losses on adverse purchase commitments associated with the purchase of materials to support the
manufacture of product for Sinovel. See Item 3 Legal Proceedings and Item 7, Managements Discussion and Analysis of Financial Condition and Results of Operations, for further discussion of the Sinovel matter.

Working capital for the fiscal year ended March 31, 2011 included the November 2010 issuance of 4,600,000 shares of
common stock at a price of $35.50 per share in a public equity offering, which resulted in net proceeds to the Company of approximately $155.2 million, after deducting the underwriting costs and offering expenses of $8.1 million.

Net income for the fiscal year ended March 31, 2010 included $13.5 million in employee stock-based compensation expense and a $0.5
million charge primarily for restructuring related to our decision to consolidate our Massachusetts operations into one facility in Devens, Massachusetts. Net loss for the fiscal year ended March 31, 2009 included $9.7 million in employee
stock-based compensation expense and a $1.0 million charge primarily for restructuring related to our decision to consolidate our Massachusetts operations into one facility in Devens, Massachusetts. Net loss for the fiscal year ended March 31,
2008 included $5.7 million in employee stock-based compensation expense, a $6.7 million charge for restructuring and $0.8 million in long-lived asset impairments.

|------- | -----------------------------------------------------------------------------------

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.



| |  |  | Wind.Through our Windtec Solutions, our Wind business segment enables manufacturers to field wind turbines with
exceptional power output, reliability and affordability. We license our highly engineered wind turbine designs, provide extensive customer support services and supply advanced power electronics and control systems to wind turbine manufactures. Our
design portfolio includes a broad range of drive trains and power ratings up to 10 megawatts. We believe our unique engineering capabilities, ranging from bearings to advanced synchronous generators to blades, enables us to provide our partners with
highly-optimized wind turbine platforms. Furthermore, these designs and support services typically lead to sales of our power electronics and software-based control systems, which are designed for optimized performance, efficiency and grid
compatibility.

| |  |  | Grid.Through our Gridtec Solutions, our Grid business segment enables electric utilities and renewable energy project
developers to connect, transmit and distribute power with exceptional efficiency, reliability and affordability. We provide transmission planning services that allow us to identify power grid congestion, poor power quality and other risks, which
help us determine how our solutions can improve network performance. These services often lead to sales of grid interconnection solutions for wind farms and solar power plants, power quality systems and transmission and distribution cable systems.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Prior to April 1, 2011, we segmented our operations through two technology-centric business units: AMSC
Power Systems and AMSC Superconductors. AMSC Power Systems included all of our Wind products, as well as Grid products that regulate voltage for wind farm voltage electric utilities, renewable generation project developers and industrial operations.
Solutions from our AMSC Superconductors business unit have been incorporated into our Grid business unit. We have reclassified prior period segment information in the Annual Report on Form 10-K to reflect our new segments.

Our fiscal year begins on April 1 and ends on March 31. When we refer to a particular fiscal year, we are referring to the
fiscal year beginning on April 1 of that same year. For example, fiscal 2011 refers to the fiscal year beginning on April 1, 2011. Other fiscal years follow similarly.

Our cash requirements depend on numerous factors, including managing our adverse purchase
commitments, 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 U.S. government funding during the product development phase. Significant deviations to our business plan with regard to these factors, which are important drivers to our business, could have a material adverse effect on our
operating performance, financial condition, and future business prospects. We expect to pursue the expansion of our operations through internal growth, diversification of our customer base, and potential strategic alliances. See below for a
discussion of liquidity and capital resources.

In fiscal year 2011, two customers, Inox Wind and Doosan Heavy Industries,
accounted for approximately 18% and 11%, respectively, of our total revenues. Sinovel had been our largest customer, accounting for 68% and 70% of our total revenue for fiscal 2010 and 2009, respectively. We did not have any revenues from Sinovel in
fiscal 2011. Sinovel was the only customer accounting for more than 10% of our total revenue for fiscal years 2010 and 2009. We derived our revenues from Sinovel through sales of core electrical components as well as development contracts for the
design of wind turbines. On March 31, 2011, Sinovel refused to accept contracted scheduled shipments with a revenue value of approximately $65.2 million. In addition, we had approximately $62.0 million (excluding value added tax) owed
to us for prior shipments from Sinovel as of March 31, 2011, for which we neither recorded as revenue nor as a receivable. The last payment received from Sinovel was in early March 2011.

During March 2011, we engaged in discussions with Sinovel 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.

We cannot provide any assurance as to the outcome of these legal actions. We are now operating our business under the assumption that
Sinovel will not be a customer. For more information about these legal proceedings, see Part I, Item 3, Legal Proceedings.

Results of Operations

As discussed above, the loss of Sinovel as a customer has materially and adversely affected our business and results of operations.
Because Sinovel has accounted for more than two-thirds of our total revenue for fiscal 2010 and 2009, we experienced significantly lower revenues and significant operating losses for the fiscal years ended March 31, 2011 and March 31,
2012. Since no cash payments were made by Sinovel in the fiscal year ended March 31, 2012 for past shipments, we recognized no revenue from Sinovel during that period.

Fiscal Years Ended March 31, 2012 and March 31, 2011

Revenues

Total revenues decreased by 73% to $76.5 million in fiscal 2011 from $286.6 million for fiscal 2010. Our revenues are summarized as follows (in thousands):

Revenues in our Wind business unit consist of revenues from wind turbine electrical systems and core
components, wind turbine license and development contracts, service contracts and consulting arrangements. Our Wind business unit accounted for 58% of total revenues for fiscal year 2011 and 81% for fiscal year 2010. Revenues in the Wind business
unit decreased 81% to $44.6 million in fiscal 2011 from $231.8 million in fiscal 2010. The decrease in Wind business unit revenues was driven primarily by the situation with Sinovel. Revenues from Sinovel were $194.8 million in fiscal 2010.

Based on the average Euro and Renminbi exchange rates in fiscal 2011, revenues denominated in these foreign currencies
translated into U.S. dollars were $0.6 million higher compared to the translation of these revenues using the average exchange rates of these currencies for fiscal 2010.

Revenues in our Grid business unit consist of revenues from D-VAR®, D-VAR® RT, SVC and
PowerModuleTMproduct sales contract revenues, HTS wire
sales, revenues under government-sponsored electric utility projects, and other prototype development contracts. We also engineer, install and commission our products on a turnkey basis for some customers. The Grid business unit accounted for 42%
and 19% of revenues for fiscal 2011 and 2010, respectively. Grid revenue decreased 42% to $31.9 million in fiscal 2011 from $54.8 million in fiscal 2010. The decrease in revenues was primarily due to a significant D-VAR® project in Australia

These significant projects represented 12% and 14% of our Grid business units revenue for fiscal
2011 and 2010, 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. FaultBlockerTMcable 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 September 15, 2011, DHS committed an additional $4.1 million in funding on Project HYDRA. Of the
total $29.0 million in funding expected from DHS, it has committed funding of $15.6 million to us as of March 31, 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 NAVSEA Motor Study is a project designed to test the 36.5 MW superconductor motor developed for the U.S. Navy.

Cost of Revenues and Gross Margin

Cost of revenues decreased by 73% to $82.9 million for fiscal 2011, compared to $308.2 million for fiscal 2010. Gross margin decreased to (8.3)% in fiscal 2011 from (7.5)% in fiscal 2010. Cost of revenues
in fiscal 2010 was negatively impacted by $102.7 million in non-recurring charges relating to the write-off of inventory and the recording of a liability for adverse purchase commitments in connection with the situation with Sinovel. The decrease in
gross margin in fiscal 2011 was driven primarily by the lost gross margin on sales to Sinovel, which did not occur in fiscal 2011, partially offset by the negative impact of the write-offs described above on gross margin in fiscal 2010, as well as
$1.3 million in adverse purchase commitment recoveries in fiscal 2011. Based on the average Euro and Renminbi exchange rates in fiscal 2011, costs of revenues denominated in these foreign currencies translated into U.S. dollars were $1.0 million
higher compared to the translation of these cost of revenues using the average exchange rates of these currencies for fiscal 2010.

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):

R&D expenses (exclusive of amounts classified as cost of revenues and amounts offset by cost-sharing
funding) decreased by 16% to $27.3 million, or 36% of revenue, for fiscal 2011 from $32.5 million, or 11% of revenue, for fiscal 2010. The decrease in R&D expenses was primarily due to decreased headcount and related labor spending as a result
of restructuring activities undertaken in fiscal 2011. The decrease in R&D expenditures reclassified to cost of revenue was primarily driven by lower development project related revenue. Aggregated R&D expenses, which include amounts
classified as cost of revenues and amounts offset by cost-sharing funding, decreased 23% to $39.4 million, or 52% of revenue, for fiscal 2011, compared to $51.0 million, or 18% of revenue, for fiscal 2010. The increase in fiscal 2011 was driven
primarily by the net impact of the factors described above.

We present aggregated R&D, which is a measure (a
non-GAAP measure) not calculated in accordance with generally accepted accounting principles in the United States of America (GAAP), because we believe it provides useful information on our aggregate R&D spending and
because R&D expenses as reported on the consolidated statements of operations have been, and may in the future be, subject to significant fluctuations solely as a result of changes in the level of externally-funded contract development work,
resulting in significant changes in the amount of the cost recorded as costs of revenues rather than as R&D expenses, as discussed above.

Selling, general, and administrative

SG&A expenses decreased by
less than 1% to $72.1 million, or 94% of revenue, in fiscal 2011 from $72.4 million, or 25% of revenue, in fiscal 2010. Fiscal 2011 SG&A expenses included approximately $5.8 million in legal expenses related to the issue with Sinovel,
a $4.9 million expense of patent costs as a result of changing our accounting policy for legal costs to defend and maintain our patents and $2.1 million in severance costs for our former Chief Executive Officer. Fiscal 2010 SG&A expenses
included $5.9 million in charges for the write-off of prepaid value-added taxes associated with the Sinovel matter. The decrease in SG&A expenses was primarily related to our headcount reductions in fiscal 2011, partially offset by effect of the
charges described above.

Amortization of acquisition related intangibles

We recorded $1.0 million in fiscal 2011 and $1.5 million in fiscal 2010 in amortization related to our contractual relationships/backlog,
customer relationships, core technology and know-how, trade names and trademark intangible assets. The lower amortization in fiscal 2011was primarily driven by the write-off of certain intangible assets in fiscal 2010.

Write-off of advance payment

In October 2011, we terminated our previously planned acquisition of The Switch due to adverse market conditions for a financing required to fund the acquisition. As a result, The Switch retained a $20.6
million advance payment as a break-up fee, and we recorded a write-off of the advance payment during the year ended March 31, 2012.

Restructuring and impairments

During fiscal 2011, we undertook a systematic restructuring of our operations as a result of the material changes in our business
resulting from the situation with Sinovel, which was approved by the Board of Directors. These actions resulted in the reduction of approximately 50% of our headcount and are expected to generate approximately $50 million in annual savings. We
recorded restructuring and impairment charges of $9.2 million for the year ended March 31, 2012. These charges primarily consisted of employee severance and benefit costs related to the restructuring plan of $5.3 million, impairment charges of
$1.7 million on long-lived assets for which there is no remaining future economic benefit as of March 31, 2012 and facility exit costs of $2.2 million related to the remaining lease commitments and certain asset impairments on the leased space
in our Klagenfurt and Middleton locations.

Wind generated an operating loss of $62.2 million in fiscal 2011 compared to an operating loss of $100.5
million in fiscal 2010. The decrease in operating loss for fiscal 2011 was primarily attributable to cost reduction efforts as well as charges described above in fiscal 2010 related to the situation with Sinovel that did not recur in fiscal 2011.

Grid operating loss decreased to $29.6 million in fiscal 2011 from $63.9 million in fiscal 2010. The decrease in operating
loss for fiscal 2011 is primarily attributed to the cost reduction efforts described above, partially offset by lower Grid revenues.

Unallocated corporate expenses in fiscal 2011 included the write-off of the advance payment to The Switch of $20.6 million, restructuring and impairment charges of $9.2 million, and expense of patent
costs of $4.9 million related to changing our accounting policy for legal costs to defend and maintain our patents. Unallocated corporate expenses also included $9.9 million in stock-based compensation expense for fiscal 2011 compared to $13.4
million in stock-based compensation expense for fiscal 2010.

Interest income, net

Interest income, net was $0.2 million and $0.8 million for fiscal 2011 and 2010, respectively. The decrease in interest income, net was
driven by lower cash balances.

Other income (expense), net

Other income (expense), net was $0.7 million in fiscal 2011, compared to $6.8 million in fiscal 2010. The decrease in other income
(expense), net was due primarily to lower foreign exchange and hedging gains in fiscal 2011, compared to fiscal 2010. The primary components of other income (expense), net include net foreign currency translation gain of $3.1 million partially
offset by aggregate losses on minority investments in Blade Dynamics and Tres Amigas of $2.4 million for fiscal 2011.

We recorded income tax expense of $1.4 million during fiscal 2011, compared to $16.0 million during fiscal 2010. The decrease in income tax expense was driven by lower income in foreign jurisdictions.
Certain asset write-offs in our foreign jurisdictions are considered permanent differences and are not tax deductible. Other

asset write-offs, such as inventory and prepaid value added taxes in China in fiscal 2010, are not currently deductible and result in deferred tax assets. Due to uncertainty around the
realizability of these deferred tax assets, they have been fully reserved as of fiscal years ended March 31, 2011 and March 31, 2012.

Please refer to the Risk Factors section in Part I, Item 1A, for a discussion of certain factors that may affect our future results of operations and financial condition.

Fiscal Years Ended March 31, 2011 and March 31, 2010

Revenues

Total revenues decreased by 9% to $286.6 million in fiscal
2010 from $316.0 million for fiscal 2009. Our revenues are summarized as follows (in thousands):

Our Wind business unit accounted for 81% and 80% of total revenues for fiscal 2010 and
2009, respectively. Revenues in the Wind business unit decreased 8% to $231.8 million in fiscal 2010 from $251.5 million in fiscal 2009. Wind business unit revenues were negatively impacted by the March 31, 2011 refusal by Sinovel 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 with a potential revenue value of approximately $65.2 million. In conjunction with the application of
cash basis accounting for certain of our other customers in China beginning in the three months ended September 30, 2010 and Sinovel beginning in the three months ended December 31, 2010, cash received is applied first against accounts
receivable balances, then costs of shipments (inventory and value added taxes) before recognizing any gross margin. This resulted in additional decreases in revenue recognized from Sinovel and certain of our other customers in China during fiscal
2010. Revenues from Sinovel were $194.8 million and $221.8 million in fiscal 2010 and 2009, respectively. Based on the average Euro and Renminbi exchange rates in fiscal 2010, revenues denominated in these foreign currencies translated into U.S.
dollars were $2.1 million higher compared to the translation of these revenues using the average exchange rates of these currencies for fiscal 2009.

Our Grid business unit accounted for 19% and 20% of revenues for fiscal 2010 and 2009, respectively. Grid revenue decreased 15% to $54.8 million in fiscal 2010 from $64.5 million in fiscal 2009. The
decrease in revenues was driven primarily by lower D-VAR® RT revenues and turn-key D-VAR® revenues in the US, partially offset by revenue from a large Australian D-VAR® project in fiscal 2010 . Revenues from significant Grid government-funded contract revenues are summarized as
follows (in thousands):

Of the total $24.9 million in funding expected from Department of Homeland Security
(DHS) as of March 31, 2011, DHS has committed funding of $12.6 million to us as of that date.

Cost of Revenues and Gross Margin

Cost of revenues increased by 53% to $308.2 million for fiscal 2010, compared to $201.0 million for fiscal 2009. Gross margin decreased to (7.5)% in fiscal 2010 from 36.4% in fiscal 2009. Cost of revenues
in fiscal 2010 was negatively impacted by $102.7 million in non-recurring charges relating to the write-off of inventory and the recording of a liability for adverse purchase commitments in connection with the situation with Sinovel. The decrease in
gross margin in fiscal 2010 as compared to fiscal 2009 was primarily attributed to the write-offs described above and the application of cash basis accounting for Sinovel and certain of our other customers in China beginning in the three months
ended December 31, 2010. Cash received is applied first against accounts receivable balances, then costs of shipments (inventory and value added taxes) before recognizing any gross margin. This resulted in decreases in revenues, cost of
revenues and gross margin from Sinovel and certain of our other customers in China during the fiscal year ended March 31, 2011.

Based on the average Euro and Renminbi exchange rates in fiscal 2010, costs of revenues denominated in these foreign currencies translated into U.S. dollars were $3.8 million higher compared to the
translation of these cost of revenues using the average exchange rates of these currencies for fiscal 2009.

R&D expenses (exclusive of amounts classified as cost of revenues and amounts offset by cost-sharing
funding) increased by 38% to $32.5 million, or 11% of revenue, for fiscal 2010 from $23.6 million, or 7% of revenue, for fiscal 2009. The increase in R&D expenses was driven primarily by increased headcount and related labor spending, as well as
added material and overhead spending to support new product development in our Wind business unit. The increase in R&D expenditures reclassified to cost of revenue was a result of increased efforts under license and development contracts for
wind turbine designs at AMSC Austria compared to the prior year. Aggregated R&D expenses, which include amounts classified as cost of revenues and amounts offset by cost-sharing funding, increased 29% to $51.0 million, or 18% of revenue, for
fiscal 2010, compared to $39.4 million, or 12% of revenue, for fiscal 2009. The increase in fiscal 2010 was driven primarily by the net impact of the factors described above.

Selling, general, and administrative

SG&A expenses increased by
43% to $72.4 million, or 25% of revenue, in fiscal 2010 from $50.4 million, or 16% of revenue, in fiscal 2009. The increase in SG&A expenses was primarily attributed to write-offs of certain prepaid value added taxes due to collectability not
being reasonably assured for prior shipments to certain customers in China, as well as higher labor and related costs driven by headcount growth and costs incurred related to the implementation of our new enterprise resource planning system. Also
included in the accompanying consolidated statements of operations for the year ended March 31, 2011 are acquisition-related costs of approximately $1.0 million related to the proposed acquisition of The Switch.

Amortization of acquisition related intangibles

We recorded $1.5 million in fiscal 2010 and $1.8 million in fiscal 2009 in amortization related to our contractual relationships/backlog,
customer relationships, core technology and know-how, trade names and trademark intangible assets. These intangible assets are a result of our Windtec and PQS acquisitions.

Restructuring and impairments

We performed our annual assessment of
goodwill of the Windtec and PSNA reporting units on March 31, 2011. As a result of reductions in our revenue and operating forecasts related to Sinovel and certain of our other customers in China, we determined that the goodwill related to both
the Windtec and PSNA reporting units was fully impaired. Accordingly, we recorded impairment charges of $42.1 million and $6.9 million for the Windtec and PSNA reporting units, respectively, during the fourth quarter of fiscal 2010.

In connection with the assessment of the goodwill of the Windtec and PSNA reporting units, we performed an evaluation of our long-lived
assets and intangible assets for potential impairment during the fourth quarter of fiscal 2010. As a result of reductions in our revenue and operating forecasts related to Sinovel and certain of our other customers in China, we determined that
certain of our property, plant and equipment and intangible assets were impaired. Accordingly, we recorded impairment charges of $1.0 million during the fourth quarter of fiscal 2010.

On October 25, 2007, our Board of Directors approved a restructuring plan (the Fiscal 2007 Plan) to reduce operating
costs through the closure of our last remaining facility in Westborough, Massachusetts and the consolidation of operations there, including our corporate headquarters, into our Devens, Massachusetts facility. No headcount reductions were associated
with this plan. Aggregate restructuring charges associated with the Fiscal 2007 Plan were $7.9 million, of which $0.5 million was recorded in fiscal 2009 related to the closure of our Westborough, Massachusetts facility. All restructuring charges
associated with the Fiscal 2007 Plan have resulted in cash disbursements and had been completed at the end of the second quarter of fiscal 2009. Cash paid under this plan was $0 in fiscal 2010 and $2.6 million in fiscal 2009.

Wind generated an operating loss of $100.5 in fiscal 2010 compared to operating income of $91.0 million in
fiscal 2009. The decrease in operating income in fiscal 2010 was primarily attributable to Sinovels refusal to accept shipments on March 31, 2011, which resulted in lower revenues, the charges recorded in fiscal 2010 related to the
situation with Sinovel, and the application of cash basis accounting for certain of our customers in China.

Grid operating
loss increased to $63.9 million in fiscal 2010 from $37.8 million in fiscal 2009. The increase in operating loss for fiscal 2010 is primarily due to lower sales, as described above.

Unallocated corporate expenses include stock-based compensation expense of $13.4 million for fiscal 2010 compared to $13.5 million for
fiscal 2009. Unallocated corporate expenses also include $0.5 million of restructuring charges in fiscal 2009 related primarily to the closure of our facility in Westborough, Massachusetts.

##### Table of Contents

Interest income, net

Interest income, net, was $0.8 million for both fiscal years 2010 and 2009, respectively. Due to recent economic conditions and the United
States monetary policy intended to promote growth, the yields of our interest bearing assets are low as compared to prior periods.

Other income (expense), net

Other income (expense), net, was $6.8
million in fiscal 2010, compared to a loss, net of $2.7 million in fiscal 2009. The increase in other income (expense), net was due primarily to net foreign exchange and hedging gains in fiscal 2010, compared to losses in fiscal 2009. The primary
components of other income (expense), net include net foreign currency translation and hedging gains, of $8.0 million and aggregate losses on minority investments in Blade Dynamics and Tres Amigas of $1.4 million for fiscal 2010.

Income Taxes

We recorded income tax expense of $16.0 million during fiscal 2010 and $20.5 million during fiscal 2009. Income tax expense in both periods was primarily driven by income generated in foreign
jurisdictions. Certain asset write-offs in our foreign jurisdictions such as goodwill in fiscal 2010 are considered permanent differences and are not tax deductible. Other asset write-offs in fiscal 2010, such as inventory and prepaid value added
taxes in China, are not currently deductible and result in deferred tax assets. Due to uncertainty around the realizability of these deferred tax assets, they have been fully reserved as of March 31, 2011.

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-K, however, should be considered
in addition to, and not as a substitute for, or superior to, the comparable measure prepared in accordance with GAAP.

We
define non-GAAP net (loss) income as net (loss) income before amortization of acquisition-related intangibles, restructuring and impairments, stock-based compensation, other unusual charges and any tax effects related to these items. We believe
non-GAAP net (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

|- | ------------------------------------------------------------------

We generated non-GAAP net loss of ($85.5) million, or ($1.68) per share, for fiscal 2011, compared to ($12.8) million, or ($0.27) per share, for fiscal 2010 and a non-GAAP net income of $31.7 million, or
$0.70 per share, for fiscal 2009. The increase in non-GAAP net (loss) in fiscal 2011 over 2010 was primarily related to lower revenues and the effect of the large write-offs in fiscal 2010 related to the Sinovel matter, including goodwill and
long-lived asset impairments, provisions for excess and obsolete inventory, adverse purchase commitments and write-off of prepaid value-added taxes, which totaled $158.5 million in the aggregate. The decrease in non-GAAP net income in fiscal 2010
over 2009 was primarily related to an increased expense base assuming a normalized business relationship with Sinovel and shipments of $65.9 million to certain Chinese customers in fiscal 2010 not recognized as revenue as collectability was not
reasonably assured and in some cases, the fee for shipments of products to these customers was not fixed or determinable at the time of shipment.

Liquidity and Capital Resources

At March 31, 2012, we had cash, cash
equivalents, marketable securities and restricted cash of $66.2 million, compared to $245.5 million at March 31, 2011, a decrease of $179.3 million. Our cash, cash equivalents, marketable securities and restricted cash are summarized as follows

##### Table of Contents

As of March 31, 2012, we had approximately $14.2 million of cash, cash equivalents,
marketable securities and restricted cash in foreign bank accounts.

The decrease in total cash and cash equivalents,
marketable securities and restricted cash was due primarily to the adverse change in our business in fiscal 2011 as a result of the situation with Sinovel.

For fiscal 2011, net cash used in operating activities was $141.0 million, compared to $22.8 million in fiscal 2010. The increase in cash used by operations is due primarily to an increased net loss
adjusted for non-cash charges and increase cash used for working capital, primarily due to the pay down of vendor liabilities for inventory purchased to support Sinovel.

For fiscal 2011, net cash provided by investing activities was $63.3 million, compared to net cash used in investing activities of $104.8 million in fiscal 2010. The increase in cash provided by investing
activities was driven primarily by a decrease in the net purchases of marketable securities of $163.2 million and a decrease in capital expenditures of $30.0 million, partially offset by a $20.6 million advance payment to The Switch, which was
subsequently written off, and an increase in restricted cash of $9.3 million.

For fiscal 2011, cash provided by financing
activities was $0.1 million, compared to $163.1 million provided by financing activities in fiscal 2010. The decrease in cash provided by financing activities is primarily due to the net proceeds from our public equity offering of $155.2 million in
fiscal 2010 and a decrease in proceeds from the exercise of employee stock options of $7.5 million.

At March 31, 2012 and
2011, we had $12.1 million and $5.6 million, respectively, of restricted cash included in current assets, and $2.5 of restricted cash included in long-term assets as of March 31, 2012. These amounts included in restricted cash primarily
represent deposits to secure letters of credit for various supply contracts. These deposits are held in interest bearing accounts.

As of March 31, 2012, we had five performance bonds in support of customer contracts. The total value of the outstanding performance bonds is $0.8 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.

We had unused, unsecured lines of credit consisting of 2.3 million (approximately $3.1 million) in Austria as of March 31, 2012. During the year ended March 31, 2012, our unsecured
credit line with the Bank of China approximately RMB 100.0 million (approximately $15.2 million), expired and we repaid borrowings of $4.6 million. There were no borrowings with the Bank of China outstanding as of March 31, 2012.

At March 31, 2012, we had cash, cash equivalents, and marketable securities of $51.6 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 March 31, 2012, we had a global workforce of approximately 400 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. At March 31, 2012, we had accrued liabilities related to adverse purchase commitments for inventory totaling $25.9
million. We are working with our inventory suppliers to delay cash settlements and to reduce the gross liability associated with our adverse purchase commitments. During the quarter ending June 30, 2012, we agreed to provide certain vendors
with letters of credit in the amount of approximately $9.0 million which resulted in additional restricted cash of approximately $8.5 million and a reduction of our adverse purchase commitments liability of $7.4 million.

On April 4, 2012, we completed a private placement of $25.0 million of 7% senior convertible notes (Notes). See Note 18,
Subsequent Events, for further information regarding our private placement of Notes. The Notes contain certain covenants and restrictions, including, among others, that for so long as the Notes are outstanding, we will not incur any
indebtedness (other than permitted indebtedness under the Notes), permit liens on our properties (other than permitted liens under the Notes), make payments on junior securities or make

dividends. The Notes also contain limitations on the transfer of certain assets. Events of default under the Notes include failure to pay principal or interest as due on the Notes, failure to
deliver registered shares of common stock upon the holders request for conversion of part or all of the 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 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 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 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. See Note 18, Subsequent Events, for further information regarding our loan and security agreement. The loan contains certain covenants and restrictions including, among
others, a requirement to maintain a minimum unrestricted cash balance in the U.S. of at least $10.0 million at the inception of the loan, which will decrease starting November 1, 2012 and monthly thereafter by the amount of principal paid.

Although we believe that we have the ability to maintain compliance with the Notes and loan covenants and restrictions, there
can no assurance that we will be in compliance.

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 for twelve months from the balance sheet date.
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.

We are involved in legal and administrative proceedings and claims of various types. See Part I, Item 3, 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, the Company has various contractual arrangements in which minimum quantities of goods or services have been committed to be
purchased on an annual basis.

Contractual Obligations

Contractual obligations represent future cash commitments and liabilities under agreements with third parties. Operating leases include
minimum payments under leases for our facilities and certain equipment, see Item 2, Properties, for more information. Purchase commitments represent enforceable and legally binding

During fiscal 2010, we recorded losses on certain purchase commitments of $38.8 million to cost of
revenues as a result of commitments to purchase materials that were in excess of our estimated future proceeds from sales to certain of our customers in China. As of March 31, 2012, the liability for these purchase commitments has been reduced
to $25.9 million, which is due in less than a year.

In addition, during the fourth quarter of fiscal 2011, several vendors
notified us that they had suffered losses as a result of procuring safety stock in anticipation of receiving future purchase orders or contracts from us. We have accrued outstanding adverse purchase commitments based on legally binding contracts and
purchase orders that were placed with our vendors for parts with no future demand. The vendor claims for safety stock were not supported by valid purchase orders or executed contracts and not considered part of the adverse purchase commitment
liability. The claims for safety stock have not been accrued as of March 31, 2012. We have determined that although we believe that there is no legally enforceable contract for safety stock and will continue to defend our legal position that we
do not owe amounts for safety stock, that it is reasonably possible that a case may be made against us under certain situations. As the loss is reasonably possible but not probable, we have not accounted for the loss. We have determined that the
range for this potential loss is between $0 and $4 million.

Recent Accounting Pronouncements

In December 2010, the FASB issued Accounting Standards Update (ASU) No. 2010-29, Business Combinations (Topic 805), Disclosure of
Supplementary Pro forma Information for Business Combinations a consensus of the FASB Emerging Issues Task Force (ASC 2010-29). This amendment clarifies the periods for which pro forma financial information is presented. The
disclosures include pro forma revenue and earnings of the combined entity for the current reporting period as though the acquisition date for all business combinations that occurred during the year had been as of the beginning of the annual
reporting period. If comparative financial statements are presented, the pro forma revenue and earnings of the combined entity for the comparable prior reporting period should be reported as though the acquisition date for all business combinations
that occurred during the current year had been as of the beginning of the comparable prior annual reporting period. ASU 2010-29 is effective prospectively for business combinations that occur on or after the beginning of the first annual
reporting period beginning after December 15, 2010. The adoption of ASU 2010-29 did not have a material impact on our consolidated results of operations, financial condition, or cash flows.

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.

Critical Accounting Policies and Estimates

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

Revenue recognition

We recognize revenue for product sales upon
customer acceptance, which can occur at the time of delivery, installation, or post-installation, where applicable, provided persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable and
collectability is reasonably assured. Existing customers are subject to ongoing credit evaluations based on payment history and other factors. If it is determined during the arrangement that collectability is not reasonably assured, revenue is
recognized on a cash basis of accounting. Certain of our contracts involve retention amounts which are contingent upon meeting certain performance requirements through the expiration of the contract warranty periods. For contractual
arrangements that involve retention, we recognize revenue for these amounts upon the expiration of the warranty period, meeting the performance requirements and when collection of the fee is reasonably assured.

During fiscal 2010, we determined that a cash basis of accounting was appropriate for certain of our customers in China, except Sinovel,
after June 30, 2010 and for Sinovel, after September 30, 2010. Under this method of accounting, cash is applied first against accounts receivable balances, then costs of shipments (inventory and value added taxes) before recognizing any
gross margin. No shipments were made to these customers in the fiscal year ended March 31, 2012. Payments of $5.2 million were received from these customers

##### Table of Contents

during the fiscal year ended March 31, 2012, for past shipments and recorded as revenue. We had previously recognized revenues for those customers based on the receipt of shipments but prior
to its receipt of payment for such shipments.

For certain arrangements, such as prototype development contracts and certain
product sales, we record revenues using the percentage-of-completion method, measured by the relationship of costs incurred to total estimated contract costs. Percentage-of-completion revenue recognition accounting is predominantly used on certain
turnkey power systems installations for electric utilities and long-term prototype development contracts with the U.S. government. We follow this method since reasonably dependable estimates of the revenues and costs applicable to various stages of
a contract can be made. However, the ability to reliably estimate total costs at completion is challenging, especially on long-term prototype development contracts, and could result in future changes in contract estimates. For contracts where
reasonably dependable estimates of the revenues and costs cannot be made, we follow the completed-contract method.

For sales
that involve the delivery of multiple elements, we allocate revenue to each undelivered element based on the elements fair value as determined by vendor-specific objective evidence (VSOE), which is the price charged when that
element is sold separately, or third-party evidence (TPE). When VSOE and TPE are unavailable, fair value is based on our best estimate of selling price. When our estimates are used to determine fair value, management makes its
estimates using reasonable and objective evidence to determine the price utilizing a cost plus reasonable margin consistent with how we have set our pricing historically for similar products and services. We review VSOE and TPE at least annually. If
we conclude we are unable to establish fair values for one or more undelivered elements within a multiple-element arrangement using VSOE then we use TPE or our best estimate of the selling price for that unit of accounting, being the price at which
the vendor would transact if the unit of accounting were sold by the vendor regularly on a standalone basis. We adopted this new accounting standard on April 1, 2010 using the prospective method, and the adoption did not have a material impact
on our consolidated financial statements.

We occasionally enter into construction contracts that include a performance bond or
similar security. As these contracts progress, we continually assess the probability of a payout from these securities. Should we determine that such a payout is likely, we would record a liability and reduce revenue to the extent a liability is
recorded.

We enter into certain arrangements to license our technologies and to provide training services. We have determined
that the license has no standalone value to the customer and is not separable from the training. Accordingly, we account for these arrangements as a single unit of accounting, following the revenue recognition pattern of the last deliverable of the
arrangement and recognize revenue over the period of our performance and milestones that have been achieved. Costs for these arrangements are expensed as incurred.

We have elected to record taxes collected from customers on a net basis and do not include tax amounts in revenue or costs of revenue.

Customer deposits received in advance of revenue recognition are recorded as deferred revenue until customer acceptance is received.
Deferred revenue also represents the amount billed to and/or collected from commercial and government customers on contracts which permit billings to occur in advance of contract performance/revenue recognition.

Accounts Receivable

Accounts receivable consist of amounts owed by commercial companies and government agencies. Accounts receivable are stated net of allowances for doubtful accounts. Our accounts receivable relate
principally to a limited number of customers. Changes in the financial condition or operations of our customers may result in increased delayed payments or non-payments which would adversely impact our cash flows from operating activities and/or our
results of operations. As such we may require collateral, advanced payment or other security based upon the customer history and/or creditworthiness. In determining the allowance for doubtful accounts, we evaluate the collectability of accounts
receivable based primarily on the probability of recoverability based on historical collection and write-off experience, the age of past due receivables, specific customer circumstances,



46

##### Table of Contents

and current economic trends. If the financial condition of our customers were to deteriorate, resulting in an impairment of their ability to make payment, additional allowances may be required.
Failure to accurately estimate the losses for doubtful accounts and ensure that payments are received on a timely basis could have a material adverse effect on our business, financial condition and results of operations.

Inventory

Inventories include material, direct labor and related manufacturing overhead, and are stated at the lower of cost or market determined on a first-in, first-out basis. We record inventory when we take
delivery and title to the product.

Program costs may be deferred and recorded as inventory on contracts on which costs are
incurred in excess of approved contractual amounts and/or funding, if future recovery of the costs is deemed probable.

At each
balance sheet date, we evaluate our ending inventories for excess quantities and obsolescence. Inventories that management consider excess or obsolete are written down. Management considers forecasted demand in relation to the inventory on hand,
competitiveness of product offerings, market conditions and product life cycles when determining excess and obsolescence and net realizable value adjustments. Once inventory is written down and a new cost basis is established, it is not written back
up if demand increases.

We recorded an inventory write-down of $4.4 million during fiscal 2011 based on evaluating our ending
inventories for excess quantities and obsolescence. We recorded an inventory write-down of approximately $63.9 million during fiscal 2010 based on our evaluation of forecasted demand in relation to the inventory on hand and market conditions
surrounding our products as a result of the assumption that Sinovel and certain other customers in China would fail to meet their contractual obligations and demand that was previously forecasted would fail to materialize. If in any period we are
able to sell inventories that were not valued or that had been written down in a previous period, related revenues would be recorded without any offsetting charge to cost of revenues, resulting in a net benefit to its gross margin in that period. In
fiscal 2011, $0.8 million was recognized as a net benefit to gross margin for inventory previously written down in fiscal year 2010.

Purchase commitments

We periodically enter into non-cancelable
purchase contracts in order to ensure the availability of materials to support production of our products. Any commitments for products ordered but not yet received are included as purchase commitments in our contractual obligations table. We
periodically assess the need to provide for impairment on these purchase contracts and record a loss on purchase commitments when required. During fiscal 2010, we recorded losses of $38.8 million to cost of revenues as a result of commitments to
purchase materials that were in excess of our estimated future demand from certain of our customers in China. As of March 31, 2012, the balance of this liability was $25.9 million. During fiscal 2011, we adjusted our accrual for adverse
purchase commitments by $1.3 million due to settlements with vendors. Recoveries are recorded in the period that the settlements are executed.

During the fourth quarter of fiscal 2011, several vendors notified us that they had suffered losses as a result of procuring safety stock in anticipation of receiving future purchase orders or contracts
from us. We have accrued outstanding adverse purchase commitments based on legally binding contracts and purchase orders that were placed with our vendors for parts with no future demand. The vendor claims for safety stock were not supported by
valid purchase orders or executed contracts and not considered part of the adverse purchase commitment liability. The claims for safety stock have not been accrued as of March 31, 2012. We have determined that although we believe that there is
no legally enforceable contract for safety stock and will continue to defend our legal position that we do not owe amounts for safety stock, that it is reasonably possible that a case may be made against us under certain situations. As the loss is
reasonably possible but not probable, we have not accounted for the loss. We have determined that the range for this potential loss is between $0 and $4 million.

Valuation of long-lived assets

We periodically evaluate our long-lived assets consisting principally of fixed and amortizable intangible assets for potential impairment.
In accordance with the applicable accounting guidance for the treatment of long-lived assets, we review the carrying value of our long-lived assets or asset group that is held and used, including intangible assets subject to amortization, for
impairment whenever events and circumstances indicate that the carrying value of the assets may not be recoverable. Under the held and used approach, the asset or asset group to be tested for impairment should represent the lowest level for which
identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities. The determination of our asset groups involves a significant amount of judgment, assumptions, and estimates. We have three asset groups
under our two segments, PSNA, Windtec and Superconductor based on the fact that the individual subsidiary companies that support each reporting unit are dependent on one another such that the lowest level of largely independent cash flows is the
reporting unit level. We evaluate our long-lived assets whenever events or circumstances suggest that the carrying amount of an asset or group of assets may not be recoverable from the estimated undiscounted future cash flows.

Our judgments regarding the existence of impairment indicators are based on market and operational performance. Indicators of potential
impairment include:



| |  |  | a significant change in the manner in which an asset is used;
| | - |  | -------------------------------------------------------------



| |  |  | a significant decrease in the market value of an asset;
| | - |  | -------------------------------------------------------



| |  |  | identification of other impaired assets within a reporting unit;
| | - |  | ----------------------------------------------------------------



| |  |  | a significant adverse change in its business or the industry in which it is sold;
| | - |  | ---------------------------------------------------------------------------------



| |  |  | a current period operating cash flow loss combined with a history of operating or cash flow losses or a projection or forecast that demonstrates
continuing losses associated with the asset; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | significant advances in our technologies that require changes in our manufacturing process.
| | - |  | -------------------------------------------------------------------------------------------

In the third quarter of fiscal 2011, we completed certain restructuring activities to reduce costs and to align our strategic priorities
to capitalize on near and long-term opportunities in our Grid segment. As a result, we concluded that there were indicators of potential impairment of certain long-lived assets in our Grid segment and therefore conducted an assessment of the
recoverability of these assets by comparing the carrying value of the assets to the pre-tax undiscounted cash flows estimated to be generated by those assets over their remaining book useful lives. Based on the calculation performed by management,
the sum of the undiscounted cash flows forecasted to be generated by certain assets within its Grid segment were less than the carrying value of those assets. Therefore, there was an indication that certain of our Grid assets were impaired and, as a
result, we performed additional analysis. An evaluation of the level of impairment was made by comparing the implied fair value of those definite long-lived tangible and intangible assets of its Grid segment against their carrying values.

The fair values of the impacted property and equipment were based on what we could reasonably expect to sell each asset from
the perspective of a market participant. The determination of the fair value of our property and equipment included estimates and judgments regarding the marketability and ultimate sales price of individual assets. We utilized market data and
approximations from comparable analyses to arrive at the estimated fair values of the impacted property and equipment. The fair values of amortization intangible assets related to completed technology were determined using the relief-from-royalty
method over the estimated economic lives of those assets from the perspective of a market participant. We determined that certain of our Grid segment property, plant and equipment were impaired as their carrying value exceeded their fair value.
Accordingly, we recorded an impairment charge of $1.7 million.

In addition, for the year ended March 31, 2012, we
recorded $2.2 million of facility exit costs as a result of our restructuring plan.

Income taxes

Our provision for income taxes is composed of a current and a deferred portion. The current income tax provision is
calculated as the estimated taxes payable or refundable on tax returns for the current year. The



48



---

##### Table of Contents

deferred income tax provision is calculated for the estimated future tax effects attributable to temporary differences and carryforwards using expected tax rates in effect in the years during
which the differences are expected to reverse.

We regularly assess our ability to realize our deferred tax assets. Assessments
of the realization of deferred tax assets require that management consider all available evidence, both positive and negative, and make significant judgments about many factors, including the amount and likelihood of future taxable income. Based on
all the available evidence, we have recorded valuation allowances to reduce our deferred tax assets to the amount that is more likely than not to be realizable due to the taxable losses that have been incurred since our inception and uncertainty
around our future profitability.

Accounting for income taxes requires a two-step approach to recognizing and measuring
uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if, based on the technical merits, it is more likely than not that the position will be sustained upon audit, including resolution of related
appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. We re-evaluate these uncertain tax positions on a quarterly basis.
This evaluation is based on factors including, but not limited to, changes in facts or circumstances, changes in tax law, effectively settled issues under audit and new audit activity. Any changes in these factors could result in the recognition of
a tax benefit or an additional charge to the tax provision. We include interest and penalties related to gross unrecognized tax benefits within the provision for income taxes, see Note 10, Income Taxes, of our consolidated financial
statements for further information regarding our income tax assumptions and expenses.

Stock-based compensation

We measure compensation cost arising from the grant of share-based payments to employees at fair value and recognize
such cost over the period during which the employee is required to provide service in exchange for the award, usually the vesting period. Total stock-based compensation expense recognized during the fiscal years ended March 31, 2012, 2011, and
2010 was $9.9 million, $13.4 million, and $13.5 million, respectively. For awards with service conditions only, we recognize compensation cost on a straight-line basis over the requisite service/vesting period. We use the lattice model to value
market condition awards. For awards with market conditions with a single cliff vest feature, we recognize compensation costs on a straight-line basis over the requisite service period. For awards with performance condition, accruals of compensation
cost are made based on the probable outcome of the performance conditions. The cumulative effect of changes in the probability outcomes are recorded in the period in which the changes occur.

Determining the appropriate fair value model and calculating the fair value of share-based payment awards requires the input of highly
subjective assumptions, including the expected life of the share-based payment awards and stock price volatility. Management determined that expected volatility rates should be estimated based on historical and implied volatilities of our common
stock. The expected term represents the average time that the options that vest are expected to be outstanding based on the vesting provisions and our historical exercise, cancellation and expiration patterns. The assumptions used in calculating the
fair value of share-based payment awards represent managements best estimates, but these estimates involve inherent uncertainties and the application of management judgment. As a result, if circumstances change and we use different
assumptions, our stock-based compensation expense could be materially different in the future. In addition, we are required to estimate an expected forfeiture rate and only recognize expense for those shares expected to vest. If our actual
forfeiture rate is materially different from our estimate, the stock-based compensation expense could be significantly different from what we have recorded in the current period, See Note 11, Stockholders Equity, of our
consolidated financial statements for further information regarding our stock-based compensation assumptions and expenses.

Derivatives

Our foreign currency risk management strategy is principally designed to mitigate the potential financial impact of changes in the value of transactions and balances denominated in foreign currency
resulting from changes in foreign currency exchange rates. Our foreign currency hedging program uses both forward contracts



49



---

##### Table of Contents

and currency options to manage the foreign currency exposures that exist as part of our ongoing business operations. We recognize all derivatives, including forward currency-exchange contracts,
in the balance sheet at fair value.

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

For forward foreign exchange contracts that are designated as cash flow hedges, if they are effective in offsetting the variability of the
hedged cash flows, and otherwise meet the hedge accounting criteria, changes in the derivatives value are not included in current earnings but are included in other comprehensive income in stockholders equity. The changes in fair value will
subsequently be reclassified into earnings as a component of cost of revenues, as applicable, when the forecasted transaction occurs. Effectiveness is assessed at the inception of the hedge and on a quarterly basis. To the extent that a previously
forecasted transaction is no longer an effective hedge, any ineffectiveness measured in the hedging relationship is recorded in earnings in the period the ineffectiveness occurs. Realized gains and losses resulting from these cash flow hedges offset
the foreign exchange gains and losses on the underlying transactions being hedged. Gains and losses on derivatives not designated for hedge accounting or representing either hedge ineffectiveness or hedge components excluded from the assessment of
effectiveness are recognized in other income (expense), net. The assessments determine whether derivatives designated as qualifying hedges continue to be highly effective in offsetting changes in the cash flows of hedged items. Any ineffective
portion of the change in fair value is included in current period earnings. Cash flow hedge accounting is deemed ineffective when the forecasted transaction is no longer probable of occurring on the originally forecasted date, or 60 days thereafter.
On March 31, 2011, we determined our hedges for forward foreign exchange contracts outstanding were no longer effective based on our determination that the original forecasted transactions were not probable of occurring by the end of the
originally specified time period. As a result, we reclassified accumulated gains of $1.6 million from accumulated other comprehensive income (loss) to other income (expense), net, in the accompanying consolidated statements of operations.

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

Contingencies

From time to time, we are involved in legal and administrative proceedings and claims of various types. 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 adjusts the loss
provision when appropriate. If the loss is not probable or cannot be reasonably estimated, a liability is not recorded in its consolidated financial statements. If, with respect to a matter, it is not both probable to result in liability and
the amount of loss cannot be reasonably estimated, an estimate of possible loss or range of loss shall be disclosed unless such an estimate cannot be made. We do not recognize gain contingencies until they are realized. Legal costs incurred in
connection with loss contingencies are expensed as incurred.

Product Warranty

Warranty obligations are incurred in connection with the sale of our products. We generally provide a one to three year warranty on our
products, commencing upon installation. The costs incurred to provide for these warranty obligations are estimated and recorded as an accrued liability at the time of sale. Future warranty costs are estimated based on historical performance rates
and related costs to repair given products. The accounting estimate related to product warranty involves judgment in determining future estimated warranty costs. Should actual performance rates or repair costs differ from estimates, revision to the
estimated warranty liability would be required.

|Item 7A. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
|-------- | ----------------------------------------------------------

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

Cash and cash equivalents

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

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 (losses), net of hedging activities, are included in net income and were $3.1 million, $8.0 million and
($2.5) million for the fiscal years ended March 31, 2012, 2011 and 2010, respectively.

Cash Flow Hedges

At March 31, 2011, we had forward contracts outstanding to hedge cash flow exposure at our wholly-owned Austrian
subsidiary, AMSC Austria, with aggregate U.S. dollar equivalent notional amounts of $40.9 million. These contracts expired at various dates through March 2012. On March 31, 2011, we determined our hedges for forward foreign exchange contracts
were no longer valid based on our determination that the original forecasted transactions were no longer considered probable of occurring by the end of the originally specified time period. As a result, we reclassified accumulated gains of $1.6
million from accumulated other comprehensive income (loss) to other income (expense), net, in the accompanying consolidated statements of operations.

Report of Independent Registered Public Accounting Firm

To the
Board of Directors and Stockholders of

American Superconductor Corporation

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of operations, of comprehensive
(loss) income, of stockholders equity and of cash flows present fairly, in all material respects, the financial position of American Superconductor Corporation and its subsidiaries at March 31, 2012 and March 31, 2011, and the
results of their operations and their cash flows for each of the three years in the period ended March 31, 2012 in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the
financial statement schedule listed in the index appearing under Item 15(a)(2) presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. Also in our
opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of March 31, 2012, based on criteria established in Internal Control  Integrated Framework issued by the Committee of
Sponsoring Organizations of the Treadway Commission (COSO). The Companys management is responsible for these financial statements and financial statement schedule, for maintaining effective internal control over financial reporting and for its
assessment of the effectiveness of internal control over financial reporting included in Managements Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on these financial
statements, on the financial statement schedule and on the Companys internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight
Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial
reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing
the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the
circumstances. We believe that our audits provide a reasonable basis for our opinions.

A companys internal control over
financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.
A companys internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the
assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures
of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of
the companys assets that could have a material effect on the financial statements.

Because of its inherent limitations,
internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions,
or that the degree of compliance with the policies or procedures may deteriorate.

AMERICAN SUPERCONDUCTOR CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.    Nature of the Business and Operations

American Superconductor Corporation (AMSC or the Company) 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.

At March 31, 2012, the Company had cash, cash equivalents, and marketable securities of $51.6 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 March 31, 2012, the Company had a global workforce of approximately 400 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. At March 31, 2012, the Company had
accrued liabilities related to adverse purchase commitments for inventory totaling $25.9 million. 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 provide certain vendors with letters of credit in the amount of approximately $9.0 million which resulted in additional restricted cash of approximately $8.5 million
and a reduction of its adverse purchase commitments liability of $7.4 million. See Note 18, Subsequent Events, for additional information.

On April 4, 2012, the Company completed a private placement of $25.0 million of 7% senior convertible notes (Notes). See Note 18, Subsequent Events, for further information
regarding the Companys private placement of Notes. The Notes contain certain covenants and restrictions, including, among others, that for so long as the Notes are outstanding, the Company will not incur any indebtedness (other than permitted
indebtedness under the Notes), permit liens on its properties (other than permitted liens under the Notes), make payments on junior securities or make dividends. The Notes also contain limitations on the transfer of certain assets. Events of default
under the Notes include failure to pay principal or interest as due on the Notes, failure to deliver registered shares of common stock upon the holders request for conversion of part or all of the 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 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 Notes in cash plus a penalty as specified in the agreement. In addition, if the Company fails to
maintain an effective registration statement covering common stock to be used in settling obligations under the Notes, the Company will be required to pay a penalty as specified in the agreement.

On June 5, 2012, the Company entered into a Loan and Security Agreement with Hercules Technology Growth Capital, under which the
Company borrowed $10.0 million. See Note 18, Subsequent Events, for further information regarding the Companys Loan and Security Agreement. The loan contains certain covenants and restrictions including, among others, a requirement
to maintain a minimum unrestricted cash balance in the U.S. of at least $10.0 million at the inception of the loan, which will decrease starting November 1, 2012 and monthly thereafter by the amount of principal paid.

Although the Company believes that it has the ability to maintain compliance with the Notes and loan covenants and restrictions, there can
no assurance that the Company will be in compliance.

AMERICAN SUPERCONDUCTOR CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS  (Continued)



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 for twelve months from the balance sheet date.
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.

2.    Summary of Significant Accounting Policies

Basis of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany balances and transactions are eliminated. Certain
reclassifications of prior years amounts have been made to conform to the current year presentation. These reclassifications had no effect on net income, cash flows from operating activities or stockholders equity.

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles of the United States of America, (GAAP) requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. The Company
bases its estimates on historical experience and various other factors believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not
readily apparent from other sources. On an ongoing basis, the Company evaluates its estimates, including those related to revenue recognition, collectability of receivables, realizability of inventory, goodwill and intangible assets, warranty
provisions, stock-based compensation, tax reserves, and deferred tax assets. Provisions for depreciation are based on their estimated useful lives using the straight-line method. Some of these estimates can be subjective and complex and,
consequently, actual results may differ from these estimates under different assumptions or conditions. While for any given estimate or assumption made by the Companys management there may be other estimates or assumptions that are reasonable,
the Company believes that, given the current facts and circumstances, it is unlikely that applying any such other reasonable estimate or assumption would materially impact the financial statements.

Cash Equivalents

The Company considers all highly liquid debt instruments with original maturities of three months or less to be cash equivalents. 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. 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. Fair values are based on quoted market prices. The unrealized gains and losses related to these securities are included in accumulated other
comprehensive income (loss). When securities are sold, the cost is determined based on the specific identification method and realized gains and losses are included in interest income, net. The Company periodically reviews the realizability of each
short 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.

Accounts Receivable

Accounts receivable consist of amounts owed by commercial companies and government agencies. Accounts receivable are stated net of
allowances for doubtful accounts. The Companys accounts receivable relate principally to a limited number of customers. Changes in the financial condition or operations of our customers may result in increased delayed payments or non-payments
which would adversely impact its cash flows from operating activities and/or its results of operations. As such the Company may require collateral, advanced payment or other security based upon the customer history and/or creditworthiness. In
determining the allowance for doubtful accounts, the Company evaluates the collectability of accounts receivable based primarily on the probability of recoverability based on historical collection and write-off experience, the age of past due
receivables, specific customer circumstances, and current economic trends. If the financial condition of the Companys customers were to deteriorate, resulting in an impairment of their ability to make payment, additional allowances may be
required. Failure to accurately estimate the losses for doubtful accounts and ensure that payments are received on a timely basis could have a material adverse effect on the Companys business, financial condition and results of operations.

Inventory

Inventories include material, direct labor and related manufacturing overhead, and are stated at the lower of cost or market determined on a first-in, first-out basis. The Company records inventory when
it takes delivery and title to the product.

Program costs may be deferred and recorded as inventory on contracts on which
costs are incurred in excess of approved contractual amounts and/or funding, if future recovery of the costs is deemed probable.

At each balance sheet date, the Company evaluates its ending inventories for excess quantities and obsolescence. Inventories that
management consider excess or obsolete are written down. Management considers forecasted demand in relation to the inventory on hand, competitiveness of product offerings, market conditions and product life cycles when determining excess and
obsolescence and net realizable value adjustments. Once inventory is written down and a new cost basis is established, it is not written back up if demand increases.

For the year ended March 31, 2012, the Company recorded an inventory write-down of approximately $4.4 million based on evaluating its ending inventory on hand for excess quantities and
obsolescence. The Company recorded an inventory write-down of approximately $63.9 million during the year ended March 31, 2011, based on its evaluation of forecasted demand in relation to the inventory on hand and market conditions surrounding
its products as a result of the assumption that Sinovel and certain other customers in China will fail to meet their contractual obligations and demand that was previously forecasted will fail to materialize. During the year ended March 31,
2012, the Company recorded a benefit to cost of revenues of $0.8 million related to the sale or usage of inventories written down in a prior period.

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. The Company periodically assesses the need to provide for impairment on these purchase contracts and record a loss on purchase
commitments when required. During the fourth quarter of the year ended March 31, 2011, the Company recorded losses of $38.8 million to cost of revenues as a result of commitments to purchase materials that were in excess of its estimated future
demand from certain of its customers in China. As of March 31, 2012, the Company had accrued liabilities related to adverse purchase commitments totaling $25.9 million. During the year ended March 31, 2012, the Company adjusted its accrual
for adverse purchase commitments by $1.3 million due to settlements with vendors. Recoveries are recorded in the period the settlements are executed.

During the fourth quarter of the year ended March 31, 2011, 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. 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 executed contracts and not considered part of the adverse purchase commitment liability. The claims for safety stock have not been accrued as of
March 31, 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.

Derivatives

The Companys foreign currency risk management strategy is principally designed to mitigate the potential financial impact of changes
in the value of transactions and balances denominated in foreign currency resulting from changes in foreign currency exchange rates. The Companys foreign currency hedging program uses both forward contracts and currency options to manage the
foreign currency exposures that exist as part of its ongoing business operations. The Company does not enter into derivative instruments for trading or speculative purposes.

Cash Flow Hedges

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

For forward foreign exchange contracts that are designated as cash flow hedges, if they are effective in offsetting the variability of the
hedged cash flows, and otherwise meet the hedge accounting criteria, changes in the derivatives value are not included in current earnings but are included in other comprehensive income in stockholders equity. The changes in fair value will
subsequently be reclassified into earnings as a component of cost of revenues, as applicable, when the forecasted transaction occurs. Effectiveness is assessed at the inception of the hedge and on a quarterly basis. To the extent that a previously
forecasted transaction is no longer an effective hedge, any ineffectiveness measured in the hedging relationship is recorded in earnings in the period the ineffectiveness occurs. Realized gains and losses resulting from these cash flow hedges offset
the foreign exchange gains and losses on the underlying transactions being hedged. Gains and losses on derivatives not designated for hedge accounting or representing either hedge ineffectiveness or hedge components excluded from the assessment of
effectiveness are recognized in other income (expense), net. The assessments determine whether derivatives designated as qualifying hedges continue to be highly effective in offsetting changes in the cash flows of hedged items. Any ineffective
portion of the change in fair value is included in current period earnings. Cash flow hedge accounting is deemed ineffective when the forecasted transaction is no longer probable of occurring on the originally forecasted date, or 60 days thereafter.

Balance Sheet Hedges

In addition to cash flow hedges, from time to time the Company also enters into foreign currency forward exchange contracts to mitigate the impact of foreign exchange risk related to certain
non-functional currency receivable balances in its foreign entities. The Company typically does not elect hedge accounting treatment for these hedges and consequently, changes in the fair value of these contracts are recorded within other income
(expense), net, in the period which they occur.

All derivatives, whether designated in a hedging relationship or not, are
required to be recorded on the balance sheet at fair value. This guidance also requires that changes in the derivatives fair value be recognized currently in earnings unless specific hedge accounting criteria are met, and that the Company
formally document, designate, and assess the effectiveness of transactions that receive hedge accounting. The effectiveness of the

derivative as a hedging instrument is based on changes in its market value being highly correlated with changes in the market value of the underlying hedged item.

Property, Plant and Equipment

Property, plant and equipment are carried at cost less accumulated depreciation and amortization. The Company accounts for depreciation and amortization using the straight-line method to allocate the cost
of property, plant and equipment over their estimated useful lives as follows:



|                                 |  |                                                                 
|-------------------------------- |  | ----------------------------------------------------------------
|Asset Classification             |  | Estimated Useful Life in Years                                  
|Building                         |  | 40                                                              
|Process upgrades to the building |  | 10-40                                                           
|Machinery and equipment          |  | 3-10                                                            
|Furniture and fixtures           |  | 3-5                                                             
|Leasehold improvements           |  | Shorter of the estimated useful life or the remaining lease term

Expenditures for maintenance and repairs are expensed as incurred. Upon retirement or other disposition of
assets, the costs and related accumulated depreciation are eliminated from the accounts and the resulting gain or loss is reflected in operating expenses.

Valuation of Long-Lived Assets

The Company periodically evaluates
its long-lived assets consisting principally of fixed assets and amortizable intangible assets for potential impairment. In accordance with the applicable accounting guidance for the treatment of long-lived assets, the Company reviews the carrying
value of its long-lived assets or asset group that is held and used, including intangible assets subject to amortization, for impairment whenever events and circumstances indicate that the carrying value of the assets may not be recoverable. Under
the held and used approach, the asset or asset group to be tested for impairment should represent the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities. The Company
evaluates its long-lived assets whenever events or circumstances suggest that the carrying amount of an asset or group of assets may not be recoverable from the estimated undiscounted future cash flows.

In November 2011, the Company completed certain restructuring activities in order to reduce costs and to align its strategic priorities to
capitalize on near and long-term opportunities in its Grid segment. As a result, the Company concluded that there were indicators of potential impairment of certain long-lived assets in its Grid segment and therefore conducted an assessment of the
recoverability of these assets during the three months ended December 31, 2011 by comparing the carrying value of the assets to the pre-tax undiscounted cash flows estimated to be generated by those assets over their remaining book useful
lives. Based on the calculation performed by management, the sum of the undiscounted cash flows forecasted to be generated by certain assets within its Grid segment were less than the carrying value of those assets. Therefore, there was an
indication that certain of the Companys Grid assets were impaired and, as a result, the Company performed additional analysis. An evaluation of the level of impairment was made by comparing the implied fair value of those definite long-lived
tangible and intangible assets of its Grid segment against their carrying values.

The fair values of the impacted property and
equipment were based on what the Company could reasonably expect to sell each asset from the perspective of a market participant. The determination of the fair value of its property and equipment includes estimates and judgments regarding the
marketability and ultimate sales price of individual assets. The Company utilized market data and approximations from comparable analyses to arrive at the estimated fair values of the impacted property and equipment. The fair values of amortizable
intangible assets related to completed technology were determined using the relief-from-royalty method over the estimated



62

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS  (Continued)



economic lives of those assets from the perspective of a market participant. During the three months ended December 31, 2011, the Company determined that certain of its Grid segment
property, plant and equipment were impaired as their carrying value exceeded their fair value. Accordingly, the Company recorded an impairment charge of $1.7 million.

In addition, for the year ended March 31, 2012, the Company recorded $2.2 million of facility exit costs as a result of its restructuring plan.

Equity Method Investments

The Company uses the equity method of accounting for investments in entities in which it has an ownership interest, but does not exercise a controlling interest in the operating and financial policies of
an investee. Under this method, an investment is carried at the acquisition cost, plus the Companys equity in undistributed earnings or losses since acquisition.

Revenue Recognition

The Company recognizes revenue for product
sales upon customer acceptance, which can occur at the time of delivery, installation or post-installation, provided persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable and the collectability
is reasonably assured. Existing customers are subject to ongoing credit evaluations based on payment history and other factors. If it is determined during the arrangement that collectability is not reasonably assured, revenue is recognized on a cash
basis of accounting. Certain of the Companys contracts involve retention amounts which are contingent upon meeting certain performance requirements through the expiration of the contract warranty periods. For contractual arrangements that
involve retention, the Company recognizes revenue for these amounts when upon the expiration of the warranty period, meeting the performance requirements and when collection of the fee is reasonably assured.

During the year ended March 31, 2011, the Company determined that revenues from certain of its customers in China could not be
recorded for shipments made according to the delivery terms, as the fee was not fixed or determinable or collectability was not reasonably assured. For these customers, the Company is utilizing a cash basis of accounting with cash applied first
against accounts receivable balances, then costs of shipments (inventory and value added taxes) before recognizing any gross margin. No shipments were made to these customers in the year ended March 31, 2012. Payments of $5.2 million were
received from these customers during the year ended March 31, 2012, for past shipments and recorded as revenue.

For
certain arrangements, such as contracts to perform research and development, prototype development contracts and certain product sales, the Company records revenues using the percentage-of-completion method, measured by the relationship of costs
incurred to total estimated contract costs. Percentage-of-completion revenue recognition accounting is predominantly used on long-term prototype development contracts with the U.S. government and certain commercial turnkey contracts. The Company
follows this method since reasonably dependable estimates of the revenues and costs applicable to various stages of a contract can be made. However, the ability to reliably estimate total costs at completion is challenging, especially on long-term
prototype development contracts, and could result in future changes in contract estimates. For contracts where reasonably dependable estimates of the revenues and costs cannot be made, the Company follows the completed-contract method.

For sales that involve the delivery of multiple elements, we allocate revenue to each undelivered element based on the elements fair
value as determined by vendor-specific objective evidence (VSOE), which is the price charged when that element is sold separately, or third-party evidence (TPE). When VSOE and TPE are unavailable, fair value is based on
our best estimate of selling price utilizing a cost plus reasonable margin consistent with how the Company has set pricing historically for similar products and services. When our estimates are used to determine fair value, management makes its
estimates using reasonable and objective evidence to determine the price. We review VSOE and TPE at least annually. If we conclude we are unable to



63

##### Table of Contents

AMERICAN SUPERCONDUCTOR CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS  (Continued)



establish fair values for one or more undelivered elements within a multiple-element arrangement using VSOE then we use TPE or our best estimate of the selling price for that unit of accounting,
being the price at which the vendor would transact if the unit of accounting were sold by the vendor regularly on a standalone basis.

The Company occasionally enters into construction contracts that include a performance bond. As these contracts progress, the Company continually assesses the probability of a payout from the performance
bond. Should the Company determine that such a payout is likely; the Company would record a liability. The Company would reduce revenue to the extent a liability is recorded.

The Company enters into certain arrangements to license its technologies and to provide training services. The Company has determined that the license has no standalone value to the customer and is not
separable from the training. Accordingly, the Company accounts for these arrangements as a single unit of accounting, following the revenue recognition pattern of the last deliverable of these arrangements and recognizes revenue over the period of
the Companys performance and milestones that have been achieved. Costs for these arrangements are expensed as incurred.

The Company has elected to record taxes collected from customers on a net basis and does not include tax amounts in revenue or costs of
revenue.

Customer deposits received in advance of revenue recognition are recorded as deferred revenue until customer
acceptance is received. Deferred revenue also represents the amount billed to and/or collected from commercial and government customers on contracts which permit billings to occur in advance of contract performance/revenue recognition.

Product Warranty

Warranty obligations are incurred in connection with the sale of the Companys products. The Company generally provides a one to three year warranty on its products, commencing upon installation. The
costs incurred to provide for these warranty obligations are estimated and recorded as an accrued liability at the time of sale. Future warranty costs are estimated based on historical performance rates and related costs to repair given products.
The accounting estimate related to product warranty involves judgment in determining future estimated warranty costs. Should actual performance rates or repair costs differ from estimates, revision to the estimated warranty liability would be
required.

Research and Development Costs

Research and development costs are expensed as incurred.

Income Taxes

The Companys provision for income taxes is
composed of a current and a deferred portion. The current income tax provision is calculated as the estimated taxes payable or refundable on tax returns for the current year. The deferred income tax provision is calculated for the estimated future
tax effects attributable to temporary differences and carryforwards using expected tax rates in effect in the years during which the differences are expected to reverse.

Deferred income taxes are recognized for the tax consequences in future years of differences between the tax bases of assets and liabilities and their financial reporting amounts at each fiscal year end
based on enacted tax laws and statutory tax rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce net deferred tax assets to the amount expected
to be realized. The Company has provided a valuation allowance against its U.S. and foreign deferred income tax assets since the Company believes that it is more likely than not that these deferred tax assets are not currently realizable due to
uncertainty around profitability in the future.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS  (Continued)



Accounting for income taxes requires a two-step approach to recognizing and measuring
uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if, based on the technical merits, it is more likely than not that the position will be sustained upon audit, including resolution of related
appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. The Company reevaluates these uncertain tax positions on a
quarterly basis. This evaluation is based on factors including, but not limited to, changes in facts or circumstances, changes in tax law, effectively settled issues under audit and new audit activity. Any changes in these factors could result in
the recognition of a tax benefit or an additional charge to the tax provision. The Company includes interest and penalties related to gross unrecognized tax benefits within the provision for income taxes.

Stock-Based Compensation

The Company accounts for stock-based payment transactions using a fair value-based method and recognizes the related expense in the results of operations.

Stock-based compensation is estimated at the grant date based on the fair value of the award and is recognized as expense over the
requisite service period of the award. The fair value of restricted stock awards is determined by reference to the fair market value of the Companys common stock on the date of grant. The Company uses the Black-Scholes option pricing model to
estimate the fair value of awards with service and performance conditions. For awards with service conditions only, the Company recognizes compensation cost on a straight-line basis over the requisite service/vesting period. The Company uses the
lattice model to value market condition awards. For awards with market conditions with a single cliff vest feature, the Company recognizes compensation costs on a straight-line basis over the requisite service period. For awards with performance
condition, accruals of compensation cost are made based on the probable outcome of the performance conditions. The cumulative effect of changes in the probability outcomes are recorded in the period in which the changes occur.

Determining the appropriate fair value model and related assumptions requires judgment, including estimating stock price volatilities of
the Companys common stock and expected terms. The expected volatility rates are estimated based on historical and implied volatilities of the Companys common stock. The expected term represents the average time that the options that vest
are expected to be outstanding based on the vesting provisions and the Companys historical exercise, cancellation and expiration patterns.

The Company estimates pre-vesting forfeitures when recognizing compensation expense based on historical and forward-looking factors. Changes in estimated forfeiture rates and differences between estimated
forfeiture rates and actual experience may result in significant, unanticipated increases or decreases in stock-based compensation expense from period to period. The termination of employment of certain employees who hold large numbers of
stock-based awards may also have a significant, unanticipated impact on forfeiture experience and, therefore, on stock-based compensation expense. The Company will update these assumptions on at least an annual basis and on an interim basis if
significant changes to the assumptions are warranted.

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. 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 years ended March 31, 2012, 2011, and 2010, common equivalent shares of
2,290,416, 2,631,251, and 688,300, respectively, were not included in the calculation of diluted EPS as they were considered antidilutive. The following table

Foreign Currency Translation

The functional currency of all the Companys 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. Net foreign
currency transaction and hedging gains (losses), are included in net (loss) income and were $3.1 million, $8.0 million and ($2.5) million for the years ended March 31, 2012, 2011 and 2010, respectively. The Company has no restrictions on the
foreign exchange activities of its foreign subsidiaries, including the payment of dividends and other distributions.

Risks and Uncertainties

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of
contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could materially differ from those estimates and would impact future results of
operations and cash flows.

The Company invests its available cash with high-credit, quality financial instruments and invests
primarily in investment grade-marketable securities, including, but not limited to, government obligations, money market funds and corporate debt instruments.

Several of the Companys government contracts are being funded incrementally, and as such, are subject to the future authorization, appropriation, and availability of government funding. The Company
has a history of successfully obtaining financing under incrementally-funded contracts with the U.S. government and it expects to continue to receive additional contract modifications in the year ending March 31, 2012 and beyond as incremental
funding is authorized and appropriated by the government.

Contingencies

From time to time, the Company may be 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. Management reviews these estimates in each accounting period as additional information is
known and adjusts the loss provision when appropriate. If the loss is not probable or cannot be reasonably estimated, a liability is not recorded in the consolidated financial statements. If, with respect to a matter, it is not both probable to
result in liability and the amount of loss cannot be reasonably estimated, an estimate of possible loss or range of loss is disclosed unless such an estimate cannot be made. The Company does not recognize gain contingencies until they are realized.
Legal costs incurred in connection with loss contingencies are expensed as incurred. See Note 12, Commitments and Contingencies, for further information regarding the Companys pending litigation.

Disclosure of Fair Value of Financial Instruments

The Companys financial instruments consist principally of cash and cash equivalents, marketable securities, accounts receivable, accounts payable and accrued expenses. The carrying amounts of these
instruments approximate fair value.

3.    Marketable Securities and Fair Value Disclosures

Marketable Securities

The Companys marketable securities are classified as available-for-sale securities and, accordingly, are recorded at fair value. The
difference between amortized cost and fair value is included in stockholders equity. At March 31, 2012 and 2011, there were investments with an immaterial gross unrealized loss.

The following is a summary of marketable securities at March 31, 2012 and 2011 (in thousands):

Fair Value Hierarchy

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 and Level 2 of the fair value measurement hierarchy during the years ended March 31, 2012 and 2011.

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.

The following table provides the assets and liabilities carried at fair value, measured as of March 31, 2012 and 2011 (in thousands):

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 certificate of deposits and money market accounts.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS  (Continued)



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. Short-term 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.

Derivatives

The derivatives entered into by the Company are valued using over-the-counter quoted market prices for similar instruments, and are classified within Level 2 of the valuation hierarchy.

4.    Derivative Financial Instruments

Cash Flow Hedges

At March 31, 2011, the Company had forward contracts outstanding to hedge cash flow exposure at the Companys wholly-owned Austrian subsidiary, AMSC Windtec GmbH (AMSC Austria), with
aggregate U.S. dollar equivalent notional amounts of $40.9 million. These contracts expired at various dates through March 2012. At March 31, 2011, the Company determined, that these forward foreign exchange contracts outstanding were no longer
effective hedges based on the Companys determination that the original forecasted transactions were not probable of occurring by the end of the originally specified time period. As a result, the Company reclassified accumulated gains of $1.6
million from accumulated other comprehensive income (loss) to other income (expense), net, in the accompanying consolidated statements of operations. At March 31, 2012, the Company had no forward foreign exchange contracts outstanding.

The fair value amounts of asset derivatives included in prepaid expenses and other current assets and liability derivatives
included in accounts payable and accrued expenses in the consolidated balance sheets related to forward foreign exchange contracts as of March 31, 2011 were as follows (in thousands):

For the year ended March 31, 2012, the Company recorded an inventory write-down of approximately $4.4
million based on evaluating its ending inventory on hand for excess quantities and obsolescence. For the year ended March 31, 2011, the Company recorded an inventory write-down of approximately $63.9 million based on its evaluation of
forecasted demand in relation to the inventory on hand and market conditions surrounding its products as a result of the assumption that Sinovel and certain other customers in China will fail to meet their contractual obligations under existing
supply agreements and demand that was previously forecasted will fail to materialize.

Deferred program costs as of
March 31, 2012 and 2011 primarily represent costs incurred on D-VAR turnkey projects and programs accounted for under contract accounting where revenue and costs will be recognized when the Company completes the development programs.

8.    Goodwill and Other Intangible Assets

Goodwill

The Company tested goodwill for impairment at least annually and more frequently upon the occurrence of certain events, which may have indicated that impairment had occurred. The provisions of the
accounting guidance for goodwill require that a two-step impairment test be performed on goodwill. In the first step, the Company compares the fair value, which is determined using a discounted cash flow technique, of the reporting unit to its
carrying value. If the fair value of the reporting unit exceeds the carrying value of the net assets of that reporting unit, goodwill is not impaired and the Company is not required to perform further testing. If the carrying value of the net assets
assigned to the reporting unit exceeds the fair value of that unit, then the Company must perform the second step of the impairment test in order to determine the implied fair value of the reporting entitys goodwill. If the carrying value of a
reporting units goodwill exceeds it implied fair value, the Company records an impairment loss equal to the difference.

The Company performed its annual assessment of goodwill of the Windtec and PSNA reporting units on March 31, 2011. The
Companys annual assessment date corresponded with a triggering event caused by the refusal by Sinovel to accept scheduled shipments from the Company on March 31, 2011. As a result of reductions in its revenue and operating forecasts
related to Sinovel and certain of its other customers in China, the Company determined that the goodwill related to both the Windtec and PSNA reporting units was fully impaired. Accordingly, the Company recorded impairment charges of
$42.1 million and $6.9 million for the Windtec and PSNA reporting units, respectively, during the fourth quarter of the year ended March 31, 2011. The Company had no goodwill as of March 31, 2012 and March 31, 2011.

The following table presents goodwill for the year ended March 31, 2011 and 2010 is as follows (in thousands):

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS  (Continued)



The Company recorded intangible amortization expense of $2.6 million, $2.9 million, and
$2.7 million for the years ended March 31, 2012, 2011, and 2010, respectively. During the fourth quarter of the year ended March 31, 2012, the Company elected to change its accounting policy for legal costs to defend and maintain its
patents. Historically, the Company capitalized these costs and amortized them over the useful lives of the patents. In the fourth quarter, the Company determined a change to expense these costs as incurred is preferable, and elected to make that
change by expensing the remaining unamortized patent costs of $4.9 million.

Expected future amortization expense related to
intangible assets is as follows (in thousands):

The Company has provided a full valuation allowance against its net deferred income tax assets since 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 and net operating losses forecasted in the future. The Company has recorded a deferred tax
asset of approximately $14.9 million reflecting the benefit of deductions from the exercise of stock options. This deferred tax asset has been fully reserved since it is more likely than not that the tax benefit from the exercise of stock options
will not be realized. The tax benefit will be recorded as a credit to additional paid-in capital if realized.

At March 31, 2012, the Company has aggregate net operating loss carryforwards in
the U.S. for federal and state income tax purposes of approximately $620 million and $329 million, respectively, which expire in the years ending March 31, 2013 through 2032. Also included in the U.S. net operating losses is $3.7 million of
acquired losses from Power Quality Systems, Inc. Of this amount, $52.3 million results from excess tax deductions from stock option exercised in 2006 through 2012. Pursuant to the guidance on accounting for stock-based compensation, the deferred tax
asset relating to excess tax benefits from these exercises was not recognized for financial statement purposes. The future benefit from these deductions will be recorded as a credit to additional paid-in capital when realized. Research and
development and other tax credit carryforwards amounting to approximately $7.4 million and $2.8 million are available to offset federal and state income taxes, respectively, and will expire in the years ending March 31, 2013 through 2032.

At March 31, 2012, the Company has aggregate net operating loss carryforwards for its Austrian operation of approximately
$67.0 million which can be carried forward indefinitely subject to certain annual limitations. AMSC China incurred a net operating loss of $13.8 million for the year ended March 31, 2012 which can be carried forward for five years. Also the
Company had immaterial amounts of current and net operating loss carryforwards for its other foreign operations which can be carried forward indefinitely.

Section 382 of the US Internal Revenue Code of 1986, as amended (the IRC), provides limits on the extent to which a corporation that has undergone an ownership change (as defined) can
utilize any NOL and general business tax credit carryforwards it may have. The Company performed a study to determine whether Section 382 could limit the use of its carryforwards in this manner. After completing this study, the Company has
concluded that the limitation will not have a material impact on its ability to utilize its net operating loss carryforwards.

The Company evaluates its permanent reinvestment assertions with respect to foreign earnings at each reporting period. During the year
ended March 31, 2012, the Company changed its permanent reinvestment assertion with respect to only a portion of its unremitted earnings in its Austrian subsidiary. The repatriation was in the form of a loan in the amount of $13.2 million, plus
accrued interest through March 31, 2012. No income taxes were due as a result of the repatriation because of substantial tax benefits available in the United States. The Companys subsidiary in Austria has accumulated approximately $147
million of the total $149 million of estimated undistributed earnings as of March 31, 2012, which continues to be permanently reinvested by the Company.

For all other foreign subsidiaries a provision has not been made for United States or additional foreign taxes on undistributed earnings of foreign subsidiaries as the Company plans to utilize these
undistributed earnings primarily to finance operating requirements of subsidiaries outside of the United States. In the event of distribution of those earnings in the form of dividends or otherwise, the Company would be subject to U.S. income taxes,
subject to an adjustment, if any, for foreign tax credits. Determination of the amount of U.S. income tax liability that would be incurred is not practicable because of the complexities associated with this hypothetical calculation.

Accounting for income taxes requires a two-step approach to recognizing and measuring uncertain tax positions. The first step is to
evaluate the tax position for recognition by determining if, based on the technical merits, it is more likely than not that the position will be sustained upon audit, including resolution of related appeals or litigation processes, if any. The
second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. The Company reevaluates these uncertain tax positions on a quarterly basis. This evaluation is based on factors
including, but not limited to, changes in facts or circumstances, changes in tax law, effectively settled issues under audit and new audit activity. Any changes in these factors could result in the recognition of a tax benefit or an additional
charge to the tax provision. The Company has gross unrecognized tax benefits of approximately $1.1 million and $0.3 million at March 31, 2012 and 2011, respectively. These amounts represent the amount of unrecognized tax benefits that, if
recognized, would result in a reduction of the Companys effective tax rate.

During the quarter ended September 30, 2011, the Company concluded a tax audit for
the period January 1, 2006 through March 31, 2008 with its foreign subsidiary in Austria. The results of the audit concluded that previously deducted amounts for certain trade-mark and management fees related to corporate affairs charges
would no longer be tax deductible.

A tabular roll-forward of the Companys uncertainties in income tax provision
liability is presented below (in thousands):



|                           |  |   |       | 
|-------------------------- |  | - | ----- | 
|Balance at March 31, 2010  |  | $ | 195   | 
|Increase for tax positions |  |   | 102   |

|Balance at March 31, 2011  |  |   | 297   | 
|Increase for tax positions |  |   | 764   |

|                           |  |   |       | 

The Company accounts for interest and penalties related to uncertain tax positions as part of its
provision for federal and state income taxes. The Company has not recognized any interest and penalties in the current statement of operations because of the Companys offsetting net operating losses and tax credits that are available to be
carried forward. Any unrecognized tax benefits, if recognized, would favorably affect its effective tax rate in any future period. The Company does not expect that the amounts of unrecognized benefits will change significantly within the next 12
months. Interest and penalties were recorded beginning in the year ended March 31, 2011, but were immaterial amounts.

The
Company conducts business globally and, as a result, its subsidiaries file income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. Major tax jurisdictions include the U.S., China and Austria. All U.S. income
tax filings for years ending March 31, 1995 through 2012 remain open and subject to examination and all years from the year ended March 31, 2007 through 2013 remain open and subject to examination in Austria. Tax filings in China for
calendar years 2008 through 2011 will remain open and subject to examination.

11.    Stockholders Equity

Public Offering

In November 2010, the Company issued 4,600,000 shares of common stock at a price of $35.50 per share in a public equity offering, which resulted in net proceeds to the Company of approximately $155.2
million, after deducting the underwriting costs and offering expenses of $8.1 million.

stock options was $6.1 million and $10.3 million for the years ended March 31, 2012 and 2011, respectively. This expense will be recognized over a weighted-average expense period of
approximately 1.9 years. The total unrecognized compensation cost for unvested outstanding restricted stock was $5.0 million and $6.3 million for the years ended March 31, 2012 and 2011, respectively. This expense will be recognized over a

The weighted-average grant-date fair value of stock option awards granted during the years ended
March 31, 2012, 2011 and 2010 was $6.02 per share, $17.43 per share and $28.29 per share, respectively. Intrinsic value represents the amount by which the market price of the common stock exceeds the exercise price of the options. Given
the decline in the Companys stock price, exercisable options as of March 31, 2012 had minimal intrinsic value. The aggregate intrinsic value of exercisable options at March 31, 2011 and 2010 was $8.7 million and $16.4 million,
respectively. The aggregate intrinsic value of options exercised at March 31, 2011 and 2010 was $13.0 million and $11.4 million, respectively. Given the decline in the Companys stock price, the aggregate intrinsic value of options
exercised at March 31, 2012 was minimal.

The weighted average assumptions used in the Black-Scholes valuation model for stock

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 U.S. Treasury rates.

The following table summarizes
the employee and non-employee restricted stock activity for the year ended March 31, 2012:

The total fair value of restricted stock that was granted during the years ended March 31, 2012, 2011
and 2010 was $5.6 million, $10.4 million and $6.8 million, respectively. The total fair value of restricted stock that vested during the years ended March 31, 2012, 2011 and 2010 was $4.1 million, $5.5 million and $8.4 million, respectively.

The restricted stock granted during the year ended March 31, 2012 includes approximately 109,211 shares of
performance-based restricted stock, which would vest upon achievement of certain financial performance measurements. At March 31, 2011, the Company determined that certain performance measures relating to prior restricted stock grants were not
met. As a result, the Company reversed $1.8 million that had been recorded as stock-based compensation expense related to performance-based awards. Such shares were cancelled in May 2011. Included in the table above are 20,250 shares of
restricted stock units.

The remaining shares granted vest upon the passage of time. For awards that vest upon the passage of time, expense is
being recorded over the vesting period.

Stock-Based Compensation Plans

As of March 31, 2011, the Company had two active stock plans: the 2007 Stock Incentive Plan (the 2007 Plan) and the 2007
Director Stock Option Plan (the 2007 Director Plan). The 2007 Plan replaced the Companys 2004 Stock Incentive Plan upon the approval by the Companys stockholders on August 3, 2007. The 2007 Director Plan replaced the
Second Amended and Restated 1997 Director Stock Option Plan, which expired pursuant to its terms on May 2, 2007.

The
Plans provide for the issuance of restricted stock, incentive stock options and non-qualified stock options to purchase the Companys common stock. In the case of incentive stock options, the exercise price shall

be equal to at least the fair market value of the common stock, as determined by the Board of Directors, on the date of grant. The contractual life of options is generally 10 years. Options
generally vest over a 3-5 year period while restricted stock generally vests over a 2-5 year period. The 2007 Director Plan is for members of the Board of Directors who are not also employees of the Company (outside directors). Under an amendment to
the 2007 Director Plan effective April, 2009, outside directors are entitled to receive an annual award of 3,000 fully-vested shares of common stock.

As of March 31, 2012, the 2007 Plan had 1,608,057 shares and the 2007 Director Plan had 198,000 shares available for future issuance.

Employee Stock Purchase Plan

The Company has an employee stock purchase plan (ESPP) which provides employees with the opportunity to purchase shares of common stock at a price equal to the market value of the common stock at the end
of the offering period, less a 15% purchase discount. The Company recognized compensation expense of $0.1 million for each of the years ended March 31, 2012, 2011, and 2010, respectively, related to the ESPP. The Company issued 88,553 shares of
common stock related to the ESPP during the year ended March 31, 2012. As of March 31, 2012, the ESPP had 439,204 shares available for future issuance.

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 March 31, 2012 and 2011, the Company recorded a liability for adverse purchase commitments of
$25.9 million and $38.8 million, respectively. During the year ended March 31, 2012, the Company adjusted its accrual for adverse purchase commitments by $1.3 million due to settlements with vendors.

During the fourth quarter of the year ended March 31, 2011, 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. 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 executed contracts and not considered part of the adverse purchase commitment liability. The claims for safety
stock have not been accrued as of March 31, 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.

Lease Commitments

Operating leases include minimum payments under leases for our facilities and certain equipment, see Item 2, Properties.
The Companys primary leased facilities are located in Middleton and New Berlin, Wisconsin; Suzhou and Beijing, China; and Klagenfurt, Austria with a combined total of approximately 299,000 square feet of space. These leases have varying
expiration dates between April 2012 and February 2016 which can generally be terminated at our request after a six month advance notice. The Company leases other locations which focus primarily on applications engineering, sales and/or field service
and do not have significant leases or physical presence.

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 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. To date, district court has not issued an order regarding the Exchange Act claims against the Company and its officers or the Securities
Act claims against the underwriters, so those matters remain under advisement.

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 Marlboroughaction 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.

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 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.

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. The Company is
currently awaiting notice from the Beijing No. 1 Intermediate Peoples Court regarding the evidence submission deadline and 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, (2010) 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 March 31, 2012 and 2011, the Company had $12.1 million and $5.6 million,
respectively, of restricted cash included in current assets, and as of March 31, 2012, $2.5 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 will result in a reduction of its adverse purchase commitments liability of
$7.4 million. See Note 18, Subsequent Events, for additional information.

As of March 31, 2012, the Company
had five performance bonds in support of customer contracts. The total value of the outstanding performance bonds is $0.8 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.

The Company had unused,
unsecured lines of credit consisting of 2.3 million (approximately $3.1 million) in Austria as of March 31, 2012. During the year ended March 31, 2012, our unsecured credit line with the Bank

15.    Restructuring and Impairments

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, approved by the Board of
Directors, 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. From April 1, 2011 through the date of this filing, the Company
has reduced its global workforce by approximately 50%, which is expected to generate significant annual cost savings. During the year ended March 31, 2012, the Company incurred costs associated with the workforce reduction consisting of
severance pay, outplacement services, medical benefits, and other related benefits. As a result, for the year ended March 31, 2012, the Company recorded employee severance and benefit costs of $5.3 million. These charges are expected to be paid
through June 2014.

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

In addition, during the year ended March 31, 2012, the Company consolidated certain of its business
operations to reduce overall facility costs. The consolidation plan entailed vacating approximately 8,937 square feet of occupied space in Klagenfurt, Austria, approximately 33,000 square feet of unoccupied space in Middleton, WI and approximately
3,300 square feet of occupied space in Nuremburg, Germany. The Klagenfurt and Middleton facility closures were accounted for in accordance with ASC 420.With respect to the Klagenfurt location, the Company recorded a liability equal to the fair value
of the remaining lease payments as of the cease-use date. Fair value was determined based upon the discounted present value of remaining lease rentals (using a discount rate of 10.1%) for the space no longer occupied, considering future estimated
potential sublease income. With respect to the Middleton location the Company settled with its landlord a final lease payment. As a result, the Company recorded facility exit costs of $0.3 million related to the remaining lease commitments on
the leased space in Klagenfurt and Middleton locations. These charges are expected to be paid through March 2013. As of March 31, 2012, the Company had not ceased using the Nuremburg facility and therefore recorded no liability for remaining
lease payments. All restructuring charges discussed above are included within restructuring and impairments in the Companys consolidated statements of operations. The Company includes accrued restructuring within accounts payable and accrued
expenses in the consolidated balance sheets.

In addition, for the year ended March 31, 2012, the Company recorded impairment
charges of $3.6 million, primarily related to long-lived assets for which there is no remaining future economic benefit as a result of our restructuring plan and consolidation of our operations.

19.    Recent Accounting Pronouncements

In December 2010, the FASB issued Accounting Standards Update (ASU) No. 2010-29, Business Combinations (Topic
805), Disclosure of Supplementary Pro forma Information for Business Combinations a consensus of the FASB Emerging Issues Task Force (ASC 2010-29). This amendment clarifies the periods for which pro forma financial information is
presented. The disclosures include pro forma revenue and earnings of the combined entity for the current reporting period as though the acquisition date for all business combinations that occurred during the year had been as of the beginning of
the annual reporting period. If comparative financial statements are presented, the pro forma revenue and earnings of the combined entity for the comparable prior reporting period should be reported as though the acquisition date for all business
combinations that occurred during the current year had been as of the beginning of the comparable prior annual reporting period. ASU 2010-29 is effective prospectively for business combinations that occur on or after the beginning of the first
annual reporting period beginning after December 15, 2010. The adoption of ASU 2010-29 did not have a material impact on the Companys consolidated results of operations, financial condition, or cash flows.

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.

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 March 31, 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 March 31, 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.

Managements Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over our financial reporting. Internal control over financial reporting is defined in Rules 13a15(f) and
15d15(f) under the Exchange Act as a process designed by, or under the supervision of, a companys chief executive officer and chief financial officer, and effected by the board of directors, management and other personnel, to provide
reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles, and includes those policies and procedures that:

(1) Pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the
transactions and dispositions of assets;

(2) Provide reasonable assurance that transactions are recorded as
necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures are being made only in accordance with authorizations of management and directors; and

(3) Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or
disposition of assets that could have a material effect on the financial statements.

Under the supervision and with the
participation of our management, including our chief executive officer and chief financial officer, an evaluation was conducted of the effectiveness of our internal control over financial reporting based on the framework in Internal
Control  Integrated Frameworkissued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, management concluded that our internal control over financial reporting was effective as of
March 31, 2012.

The effectiveness of our internal control over financial reporting as of March 31, 2012 has been
audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which is included herein.

Changes in Internal Control over Financial Reporting

Our management previously identified material weaknesses in internal control over financial reporting related to revenues and accounts
receivable balances as fees were not fixed or determinable or collectability was not reasonably assured at the time revenue was recognized, which is described in our Annual Report on Form 10-K for the year ended March 31, 2011.

As of December 31, 2011, the following unremediated material weaknesses were as follows:



| |  |  | we did not maintain adequately designed controls to ensure accurate recognition of revenue in accordance with GAAP. Specifically, controls were not
effective to ensure that deviations from contractually established payment terms were identified, communicated and authorized;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we did not maintain adequate controls to ensure proper monitoring and evaluation of customer creditworthiness, including the collectability of amounts
due from customers and appropriate revenue recognition;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we did not maintain a sufficient complement of personnel involved with business in our foreign locations with the appropriate level of knowledge,
experience and training in the application of GAAP to ensure revenue transactions were appropriately reflected in the financial statements based on the terms and conditions of the sales contracts; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we did not establish and maintain procedures to ensure proper oversight and review, by senior management, of customer relationships to ensure
appropriate communication of relevant considerations to determine accounting judgments with respect to revenue recognition.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

During the fourth quarter of the year ended March 31, 2012, we completed the remediation of these material weaknesses and these controls were demonstrated to have operated for a sufficient period of
time. We completed the remediation in our internal controls over financial reporting by implementing the following improvements in our internal controls over financial reporting:



| |  |  | we established formal, written policies and procedures governing the customer credit process;
| | - |  | ---------------------------------------------------------------------------------------------



| |  |  | we implemented improved procedures to ensure the proper review and documentation of customer creditworthiness;
| | - |  | --------------------------------------------------------------------------------------------------------------



| |  |  | we established a new worldwide revenue manager position in finance with GAAP experience to ensure accuracy of revenue recognition;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------



| |  |  | we implemented improved procedures to ensure the proper communication, approval and accounting review of deviations from sales contracts;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we provided training to product managers and others involved in negotiating contractual arrangements and accounting for revenue transactions, and plan
to provide additional guidance in order to heighten awareness of revenue recognition concepts under GAAP; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we implemented an improved internal communication process for senior management. During monthly operations reviews time is devoted to senior management
review of pending operational and accounting issues for the current quarter.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

As mentioned above, there were
no other changes in our internal control over financial reporting during the quarter ended March 31, 2012 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
