Presentation of Information

In this Annual Report on Form 20-F (this "report"), unless the context otherwise requires, references to "AIXTRON,"
"the AIXTRON Group," the "Group" or "the Company" are to AIXTRON SE (formerly AIXTRON AG) and its consolidated subsidiaries. References to "Management" are to the Executive Board of
AIXTRON SE. Throughout this report, whenever a reference is made to AIXTRON's website, such reference does not incorporate information from the website by reference into this report.

The
Company's audited Consolidated Financial Statements are prepared in accordance with International Financial Reporting Standards (IFRS), as issued by the International Accounting
Standards Board (IASB).

AIXTRON
publishes its audited Consolidated Financial Statements in Euros. As used in this report, "EUR", "Euro" or "€" means the lawful currency of the Federal Republic
of Germany and other participating member states of the European Union. "US-Dollar",
"U.S$," or "USD" means the lawful currency of the United States of America. "Pound Sterling", "British Pounds", "GB Pounds" or "GBP" means the lawful currency of the United Kingdom.

For
convenience only (except where noted otherwise), some of the Euro amounts have been translated into US-Dollar amounts at the noon buying rate in New York for cable
transfers in Euros certified by the Federal Reserve Bank of New York for customs purposes. You should not construe these translations as a representation that Euro amounts actually represent these
US-Dollar amounts or that the Euro amounts could have been, or could be, converted into US-Dollars at those rates or at any other rate. Refer to "Key
InformationSelected Financial DataExchange Rate Information" for certain exchange rates between the Euro and the US-Dollar.

Due
to rounding, numbers presented throughout this report may not add up precisely to the totals we provide and percentages may not precisely reflect the absolute figures.

Except
where AIXTRON otherwise attributes market or industry data to another source, all such data included in this report are its own estimates. These estimates are based upon the
Company's experience in its industry and its familiarity with the relevant markets. While AIXTRON believes these estimates to be reliable, the Company has not verified them with independent sources.

Forward-Looking Statements

AIXTRON believes that various statements in this report may constitute forward-looking statements. You can identify these statements by
forward-looking words such as "may," "will," "could," "expect," "anticipate," "contemplate," "believe," "estimate," "intends," and "continue" or similar words. You should read statements that contain
these words carefully because they:



AIXTRON
believes it is important to communicate its expectations. There may be events in the future that AIXTRON is unable to predict accurately or over which the Company has no control.
The risk
factors and cautionary language discussed in this document provide examples of risks, uncertainties and events that may cause actual results to differ materially from the expectations described by
AIXTRON in its forward-looking statements, including among other things:

subsequent written and oral forward-looking statements attributable to AIXTRON or to any person acting on its behalf are expressly qualified in their entirety by the foregoing
cautionary statements. AIXTRON does not undertake and expressly disclaim any obligation to release publicly any revisions to these forward-looking statements to reflect events or circumstances after
the date of this report or to reflect the occurrence of unanticipated events.

Exchange Rate Information

The following tables set forth, for the periods indicated, information concerning the exchange rates for Euros per
US-Dollar. AIXTRON has provided these rates solely for your convenience and you should not construe these translations as a representation that Euro amounts actually represent these
US-Dollar amounts or that the Euro amounts could have been, or could be, converted into US-Dollars at those rates or at any other rate. AIXTRON did not use these rates in the
preparation of its financial statements
included elsewhere in this report. Fluctuations in the exchange rate between the US-Dollar

and
the Euro will affect the US-Dollar equivalent of the Euro price of the Company's ordinary shares traded on the Frankfurt Stock Exchange and are likely to affect the market price of the
Company's American Depositary Shares ("ADSs") traded on the NASDAQ Global Select Market.

As
used in this report, the term "noon buying rate" refers to the rate of exchange for Euro, expressed in US-Dollar per Euro, as announced by the Federal Reserve Bank of New
York for customs purposes as the rate in The City of New York for cable transfers in foreign currencies.

The
table below shows the average noon buying rates in The City of New York for cable transfers in foreign currencies as certified for customs purposes by the Federal Reserve Bank of New
York for US-Dollar per Euro for AIXTRON's last five fiscal years. The average is computed using the noon buying rate on the last business day of each month during the period indicated.

D.    Risk Factors

Any of the following risks could have a material adverse effect on AIXTRON's financial position, results of operations, liquidity and
the actual outcome of matters that the forward-looking statements contained in this annual report refer to. The risks described below are not the only ones the Company faces. There may be additional
risks AIXTRON is currently unaware of, and risks that are common to most companies. There may also be risks that AIXTRON now believes are immaterial, but which may ultimately have a material adverse
effect on the Company's financial position, results of operations, liquidity and the actual outcome of matters that the forward-looking statements contained in this annual report refer to. For
additional information regarding forward-looking statements, see "Forward-looking statements" included in this annual report.

Company-Related Risk

The compound semiconductor and the semiconductor industries can be highly volatile and unpredictable, which may adversely affect AIXTRON's operating results and result in  significant
volatility in the market price of its ordinary shares and American Depositary Shares.

The compound semiconductor and the semiconductor manufacturing equipment industry can be affected by the cyclical nature of the
semiconductor industry. Although semiconductors are used in many different products, the markets for those products are interrelated to various degrees. The industry has historically experienced
sudden changes in supply and demand for semiconductors. The

4

---



Table of Contents

timing,
length and severity of these industry cycles are difficult to predict. During periods of declining demand for semiconductor manufacturing equipment, AIXTRON needs to be able to quickly and
effectively align its cost structure with prevailing market conditions, to manage its inventory levels to reduce the possibility of future inventory write-downs resulting from obsolescence, and to
motivate and retain key employees. Because a high proportion of AIXTRON's costs are fixed in the near term, the Company's ability to reduce expenses quickly in response to revenue shortfalls is
limited. During periods of rapid growth, AIXTRON's business must be able to acquire and/or develop sufficient manufacturing capacity and inventory to meet customer demand, and to attract, hire,
assimilate and retain a sufficient number of qualified people. The Company's customers often accelerate or delay expenditures, as well as attempt to cancel or reschedule their orders, in reaction to
variations in their businesses or market conditions. As a result, AIXTRON must be able to react quickly to these changes in supply and demand. A failure to quickly align the Company's cost structure
and manufacturing capabilities with industry fluctuations could lead to significant losses or a failure to capitalize on increased demand. In either event, the results of operations may be adversely
affected, which could result in significant volatility in the market price of the Company's ordinary shares and ADSs.

Uncertainties of economic and political conditions, in particular by the current global macroeconomic situation, may adversely impact AIXTRON's financial position and  results of operations.

In 2011, the global economy was faced with major challenges arising from the sovereign debt crisis in certain Eurozone countries and
the slowing economy in the U.S. which may result in increased credit tightness issues and a continued economic slowdown in 2012. Although AIXTRON had no bank borrowings during 2011, it has cash bank
deposits. AIXTRON monitors the financial condition of its banking partners, but if one of AIXTRON's banking partners were to default before AIXTRON detected the problem or took appropriate measures,
this could adversely impact AIXTRON's financial position. A global economic slowdown might adversely affect AIXTRON's customers and suppliers. In addition to the potential for pricing pressure and
reduced demand, AIXTRON customers might delay or cancel orders and suppliers might delay or cancel deliveries, which could adversely affect AIXTRON's ability to align its production capacity with its
sales and could result in inventory write downs. These conditions might make it challenging for AIXTRON to plan and adapt, which could adversely impact AIXTRON's results of operations.

In order to compete, AIXTRON must attract, retain and motivate key employees, and its failure to do so could have an adverse effect on its results of operations.

In order to compete, AIXTRON must attract, retain and motivate executives and other key employees, including those in managerial,
technical, sales, marketing and support positions. Hiring and retaining qualified executives, scientists, engineers, technical staff and sales representatives are critical to the Company's business,
and competition for experienced employees in the semiconductor industry can be intense. To attract, retain and motivate qualified employees, AIXTRON relies heavily on paying cash compensation at
market-competitive rates and offering additional incentives and bonus payments. If such cash payments cease to be viewed as a valuable
benefit by the Company's key employees, the Company's ability to attract, retain and motivate its employees could be adversely impacted, which could negatively affect its results of operations and/or
require AIXTRON to increase the amount it expends on cash and other forms of compensation.

AIXTRON depends on a limited number of customers that operate in concentrated industries.

AIXTRON's customer base has been and may in the future be concentrated. Orders from a relatively limited number of customers have
accounted for, and likely will continue to account for, a substantial portion of the Company's revenues, which may lead customers to demand pricing and other terms less favorable to the Company. If a
principal customer discontinues its relationship with AIXTRON or suffers economic setbacks, AIXTRON's business, financial condition and operating results could be materially and adversely affected.
AIXTRON's ability to increase revenues in the future will depend in part upon its ability to obtain orders from new customers. AIXTRON cannot be certain that it will be able to do so. In addition,
because a relatively small number of large manufacturers, many of whom are AIXTRON's customers, dominate the industries in which they operate, it may be especially difficult for the Company to replace
these customers if it loses their business. A large portion of orders in AIXTRON's order backlog are orders from its principal customers. Furthermore, AIXTRON does not have long-term
contracts with many of its customers. The Company's customers may delay existing or new orders because of raw material shortages, credit/

5

Table of Contents

liquidity
tightness or delays in preparing their facilities. Any such delays could have a negative impact on customer acceptance of AIXTRON's systems, and ultimately, on its ability to generate
revenues. As a result, the Company's agreements with its customers do not provide any assurance of future revenues and AIXTRON is exposed to competitive price pressure on most new orders it attempts
to obtain. The Company's failure to obtain new orders from new or existing customers would have a negative impact on its results of operations. Because of the significant size of some orders and the
limited ability of the Company to reduce expenses quickly in response to such delays, the Company may experience volatility in its results of operations.

AIXTRON is dependent on a limited number of suppliers and the Company's operating results could be harmed if it loses access to sources of materials or services.

The systems that AIXTRON produces are complex and require the Company to manufacture or obtain through third party sources many
critical components. Many of these components are only available from a limited number of suppliers or, in some cases, a single supplier. Because of the cost of AIXTRON's systems, the Company
generally aims to keep its inventories at minimum levels. AIXTRON generally does not have long-term supply agreements with many of its suppliers. Consequently, the Company could experience
significant price
increases and/or may not be able to obtain replacement components in a timely manner or at all. Such price increases would increase the cost of goods which could adversely affect the Company's gross
margins and operating results. Because AIXTRON often does not account for a significant part of its suppliers' business, the Company may not have access to sufficient capacity from these suppliers in
periods of high demand. In addition, AIXTRON risks having important suppliers terminate product lines, change business focus or even go out of business. If AIXTRON was required to change any of its
suppliers, it would be required to re-qualify each new supplier. In the near term, the Company's supplier qualification processes could prevent or delay component shipments, which could in
turn prevent the Company from delivering products to its customers in a timely manner. AIXTRON estimates that it could take approximately six to eighteen months to replace suppliers of certain
critical components used in its systems. In addition, in connection with third-party manufacturing activities, it is possible that AIXTRON may encounter unforeseen technical complexities that it may
be unable to resolve, or that the resolution of such complexities may lead to delays in the implementation of these third-party manufacturing activities.

AIXTRON's business operates in a highly competitive industry characterized by increasingly rapid technological changes, and if the Company does not develop new products in a  timely manner, it may not be able to
compete successfully in this market.

The introduction of new products and technologies occurs at a continuously increasing pace and grows increasingly complex over time. If
AIXTRON's business does not develop and introduce new products and technologies in a timely manner in response to changing market conditions or customer requirements, its financial condition and
results of operations could be materially and adversely affected. AIXTRON's competitive advantage and future success depend on its ability to:



AIXTRON's competitors may have greater resources than AIXTRON, or may otherwise be better suited to compete in the Company's markets, and AIXTRON's failure to compete  successfully with these companies would seriously
harm its business.

Some of AIXTRON's competitors have greater financial, engineering, manufacturing and marketing resources than the Company. In addition,
AIXTRON faces competition from smaller emerging equipment companies whose strategy is to provide a portion of the products and services that the Company's semiconductor equipment business offers,
using innovative technology to sell products into specialized markets. New product introductions or enhancements by AIXTRON's competitors could cause a decline in revenues or loss of market acceptance
of AIXTRON's existing products. Increased competitive pressure could also lead to intensified price competition resulting in lower

6

Table of Contents

margins.
The Company's failure to compete successfully with these other companies would seriously harm its business.

AIXTRON faces lengthy sales and qualification cycles for its products and, in many cases, must invest a substantial amount of time and funds with no assurance that these  efforts or expenditures will result in
revenues.

Revenues from AIXTRON's systems primarily depend upon the decision of a prospective customer to invest in or upgrade its manufacturing
capabilities, which typically involves a significant capital commitment by the customer. Customers usually place orders with AIXTRON between three to nine months, or longer, after the Company's
initial contact with them regarding a particular system. AIXTRON often experiences delays in obtaining system orders while customers evaluate and receive internal approvals for the purchase of these
systems. These delays may include the time necessary to plan, design or complete a new or expanded semiconductor fabrication facility. Due to these factors, the Company expends substantial funds as
well as marketing and management efforts to sell its semiconductor production systems. These expenditures and efforts may not result in revenues.

In
order to expand its materials production capabilities, the Company has dedicated a number of its systems to the manufacture of wafers and devices. At any given time, some of AIXTRON's
products are being tested to determine whether they meet customer or industry specifications. During such a qualification period, AIXTRON invests significant resources and dedicates substantial
production capacity to the manufacture of these new products, prior to any commitment to purchase by the prospective customer and without generating significant revenues from the qualification
process. If AIXTRON was unable to meet these specifications or does not receive sufficient customer orders to
profitably use the dedicated production capacity, its business, financial condition, results of operations and cash flows could be materially and adversely affected.

AIXTRON's
future budgets for operating expenses, capital expenditures, operating leases and service contracts are based upon the Company's assumptions as to the anticipated market
acceptance of its products. If AIXTRON's products do not meet the expected customer demand, the Company's business, financial condition, results of operations and cash flows could be materially and
adversely affected.

AIXTRON's quarterly operating results fluctuate significantly, which may cause the market price of its ordinary shares and its ADSs to increase or decrease significantly.

AIXTRON has historically experienced significant fluctuations in its quarterly operating results and the Company anticipates that such
fluctuations will continue. AIXTRON's results may vary significantly depending on a number of factors, including:



In
addition, the Company derives a substantial portion of its revenues in any fiscal period from the sale of a relatively small number of high-priced systems. As a result,
the timing of recognition of revenue for a single transaction could have a material effect on total revenues and
operating results for a particular reporting period. A delay of only a week or two can often shift the related realization of revenues into the next quarter, which could adversely affect the Company's
ability to meet expectations. In addition, customers at times attempt to cancel or reschedule orders, even when not permitted to do so under the contractual terms of the purchase order.

As
stated above, AIXTRON has experienced long and unpredictable sales cycles. The timing of an order often depends on the capital expenditure budget cycle of customers. In addition, the
time it takes the Company to build a product to customer specifications, which the Company refers to as the build cycle, typically ranges from four to nine months, followed in certain cases by a
period of customer acceptance during which the customer evaluates the performance of AIXTRON's system and may

potentially
reject such system. As a result of the build cycle and evaluation periods, the period between a customer's initial purchase decision and revenue recognition on an order often varies
widely, and variations in length of this period can cause further fluctuations in operating results.

The
factors described above, together with the cyclical nature of the semiconductor industry, could cause the market price of AIXTRON's ordinary shares and its ADSs to fluctuate
significantly.

AIXTRON's business is exposed to the risks of operating an international business.

AIXTRON's business has operations located in many countries throughout the world to support the Company's sales and services to the
global semiconductor industry. Managing international operations located in many countries throughout the world presents complex management challenges. These challenges may make it more difficult for
AIXTRON to implement business strategies and enforce centralized business processes and controls across its enterprise.

AIXTRON is highly dependent on international revenues, particularly revenues from Asian countries.

Revenues outside of Europe accounted for 95.69% of the Company's total revenues for the year ended December 31, 2011, versus
96.04% for the year ended December 31, 2010, and 86.30% of total revenues for the year ended December 31, 2009. Revenues from AIXTRON's Asian-based customers accounted for 89.66% for the
year ended December 31, 2011, versus 91.46% for the year ended December 31, 2010, and 82.56% of total revenues for the year ended December 31, 2009. AIXTRON anticipates that
international revenues, including revenues from Asia, will continue to
account for a significant portion of its revenues. As a result, a significant portion of the Company's revenues will be subject to risks, including:



Wherever
currency devaluations occur abroad, AIXTRON's products become more expensive for its customers in that country. In addition, difficult economic conditions may limit capital
spending by the Company's customers. These circumstances may also affect the ability of AIXTRON's customers to meet their payment obligations, resulting in cancellations or deferrals of existing
orders and the limitation of additional orders.

Exchange rate fluctuations, in particular between the Euro, the US-Dollar and the pound sterling, could adversely affect AIXTRON's ability to price its products  competitively and its operating results.

The Company's operations are conducted by entities in many countries and a substantial portion of its sales and productions costs are
denominated in currencies other than the Euro. As a result, fluctuations between the value of the Euro and other major currencies, in particular the US-Dollar and the pound sterling, may
affect the Company's operating results. In addition, changes in monetary or other policies, including as a result of the sovereign debt crisis in certain Eurozone countries and the slowing economy in
the U.S., would also likely affect foreign currency exchange rates. AIXTRON may not be able to effectively reduce or eliminate the risk that fluctuations in foreign currencies will adversely affect
its operating results.

Further
details can be found in "Item 11, Quantitative and Qualitative Disclosure about Market Risk."

Because AIXTRON's operating income is subject to taxation in differing jurisdiction, the Company is exposed to a number of different tax risks.

Because AIXTRON operates in a number of countries throughout the world, including the U.S., its operating income is subject to taxation
in differing jurisdictions and at differing tax rates. AIXTRON seeks to organize its affairs in a tax efficient and balanced manner, taking into account the applicable regulations of the jurisdictions
in which it operates. As a result of the Company's multi-jurisdictional operations, it is exposed to a number of different tax risks, including tax risks related to: income tax, value added tax,
payroll tax, social security tax, customs and excise duties, sales and use tax, U.S. state tax, withholding tax requirements, tax treaty interpretation, tax credits, permanent establishments, transfer
pricing on internal deliveries of goods and services (including benefit tests and requirements to prove the arm's length character of internal transactions), loss carry-forwards, multi- jurisdictional
double taxation, acquisitions, dispositions, reorganizations, and internal restructurings.

The
tax authorities in the jurisdictions in which AIXTRON operates may audit the Company's tax returns and may disagree with the positions taken in those returns. An adverse outcome
resulting from any settlement or future examination of AIXTRON's tax returns may subject the Company to
additional tax liabilities and may adversely affect its effective tax rate which could have a material adverse effect on its financial position, results of operations and liquidity. In addition, any
examination by the tax authorities could cause AIXTRON to incur significant legal expenses and divert the Company's management's attention from the operation of its business.

AIXTRON is exposed to risks associated with acquisitions.

AIXTRON has in the past and may in the future undertake acquisitions of or significant investments in, other businesses with
complementary products, services or technologies. Acquisitions, or other significant investments, involve many risks, including:



AIXTRON
may not be successful in addressing the risks that its past or future acquisitions may present and the Company may fail to realize the perceived benefits of such acquisitions.

AIXTRON may increase production in anticipation of customer orders that may not materialize, which would negatively affect the Company's operating results.

AIXTRON schedules production of its systems based upon order backlog and customer commitments. Based on the complexity of the systems
that AIXTRON produces, the Company must expend considerable efforts in hiring, training and retaining qualified manufacturing personnel. AIXTRON has in the past experienced delays in customer delivery
schedules, as well as outright cancellations of orders. As a consequence, the Company may incur significant near term expenses for manufacturing capabilities that it may not be able to fully utilize,
which would negatively affect its gross margins and its profitability. Moreover, industry analysts evaluate AIXTRON's backlog in determining the Company's prospects. If AIXTRON experiences significant
reductions in its backlog as a result of

9

Table of Contents

cancellations
or the Company's failure to obtain new orders, it could experience negative ratings from analysts which could adversely impact the trading value of the Company's stock.

The semiconductor industry and AIXTRON's operations are characterized by a high percentage of costs that are fixed or otherwise difficult to reduce in the
short-term, and by product demand that is highly variable and is subject to significant downturns that may adversely affect the Company's business, results of operations and financial
condition.

The semiconductor industry and AIXTRON's operations are characterized by high costs, such as those related to facility construction and
equipment, research and development, and employment and training of a highly skilled workforce, that are either fixed or difficult to reduce in the short-term. At the same time, demand for
the Company's products is highly variable and downturns have been experienced, often in connection with maturing product cycles and downturns in general economic market conditions. These downturns
have been characterized by reduced product demand, manufacturing overcapacity, high inventory levels and decreased average selling prices. The
combination of these factors may cause AIXTRON's revenue, gross margin, cash flow and profitability to vary significantly both in the short-term and over the long-term.

AIXTRON's businesses use potentially harmful chemicals and other hazardous materials. AIXTRON is subject to environmental risks and regulations which could harm the
Company's results of operations and financial condition.

The Company's research and development activities, as well as the manufacturing and demonstration of AIXTRON's products, involve the
use of potentially harmful chemical and other hazardous or potentially hazardous materials and radioactive compounds. AIXTRON cannot completely eliminate the risk of contamination or injury from the
use, storage, handling or disposal of these materials. In the event of contamination or injury, AIXTRON could be held liable for damages that result, and any liability could exceed the Company's
resources. AIXTRON is subject to the laws and regulations of numerous jurisdictions governing the use, storage, handling and disposal of these materials and specified waste products. The Company's
cost of compliance with these laws and regulations include local, state and federal fees and costs related to the installation and maintenance of safeguards to mitigate the risk of potential release
of hazardous materials (including equipment safeguards, such as scrubbers). The amounts expended in compliance with these laws and regulations to date have not had a material effect on the Company's
capital expenditures, earnings and competitive position. However, if stricter laws were passed or applicable environmental laws were more strictly enforced, AIXTRON may incur significant additional
capital expenditure to address compliance with such environmental laws and regulations.

Failure
or inability to comply with existing or future environmental regulations could result in significant remediation liabilities, the imposition of fines and/or the suspension or
termination of production, each of which could materially and adversely affect the Company's business, financial condition, results of operations and cash flows.

In
addition, new climate change regulations could require AIXTRON to change its manufacturing processes or obtain substitute materials that may cost more or be less available for its
manufacturing operations. Furthermore, new restrictions on carbon dioxide or other greenhouse gas emissions could result in significant costs for AIXTRON. The Company expects increased worldwide
regulatory activity in the future. The cost of complying, or of failing to comply, with these and other climate change and emissions regulations could have an adverse effect on AIXTRON's business
plans and operating results.

AIXTRON is exposed to the risk that third parties may violate the Company's proprietary rights or accuse the Company of infringing upon their proprietary rights.

AIXTRON's success in the markets in which it operates may depend on its ability to operate without infringing the intellectual property
rights of others and to prevent others from infringing the Company's intellectual property rights.

There
has been substantial litigation regarding patents and other intellectual property rights in the semiconductor industry. AIXTRON may become a party to patent litigation or
proceedings to determine its patent rights with respect to third parties, including, potentially, its customers.
Interference proceedings may be necessary to establish which party was the first to discover certain intellectual property. AIXTRON may also become involved in patent litigation against third parties
to

10

---



Table of Contents

enforce
the Company's patent rights, to invalidate patents held by third parties, or to defend against similar claims by others. The cost to AIXTRON of any patent litigation or similar proceeding
could be substantial, and it may require significant management time. Any patent infringement litigation may also adversely affect the Company's ADS or ordinary share prices. If infringement
litigation against the Company was resolved unfavorably, AIXTRON may be enjoined from providing some of its products or services, or the Company may be required to obtain a license from a third party.
AIXTRON may not be able to obtain the requisite license on commercially acceptable terms at all, which could require the Company to cease selling systems that contain infringing technology until it
can identify and implement subsystems that do not infringe on third party technology. AIXTRON may not be successful in developing non-infringing solutions and may be prevented from selling
its systems, which could result in a significant reduction in the Company's revenues and a reduction in the value of its ordinary shares and ADSs.

The Company's competitive position may depend on its ability to protect its intellectual property rights and trade secrets. If AIXTRON was unable to protect such rights and
secrets, other companies may be able to compete more effectively against it, and the Company's business could suffer.

AIXTRON's success is dependent upon the protection of the Company's proprietary rights. In the high-tech industry,
intellectual property is an important asset that is always at risk of infringement. AIXTRON incurs costs to file for patents and defend its intellectual property and AIXTRON relies upon the laws of
Germany and of foreign countries in which it develops, manufactures or sells its products to protect its proprietary rights. However, there can be no assurance that these proprietary rights will
provide competitive advantages, or that other parties will not challenge, invalidate or circumvent these rights. Moreover, the laws of some foreign countries may not be as protective of intellectual
property rights as those in Germany and the United States, and mechanisms for enforcement of intellectual property rights may be inadequate. Infringement upon the Company's proprietary rights by a
third party could result in lost market and revenue opportunities for AIXTRON.

AIXTRON
relies on trade secret protection for its confidential and proprietary information and procedures. AIXTRON currently protects this information and these procedures as trade
secrets through recognized practices, including confidentiality agreements with employees, consultants, collaborators and customers. These confidentiality agreements may be breached, however, and
AIXTRON may not have adequate remedies for any breach. In addition, these trade secrets may otherwise become known to, or be independently discovered by, competitors. If AIXTRON's trade secrets were
to become known to, or be independently discovered by, competitors, the Company's competitive position and its business may be negatively impacted.

Risks Relating to holding AIXTRON's ADSs and Ordinary Shares

You may be unable to enforce a judgment against AIXTRON or members of its Executive Board or Supervisory Board.

AIXTRON is a stock corporation organized under the laws of the Federal Republic of Germany. None of the members of its Supervisory or
Executive Boards is currently a citizen or resident of the United States. Substantially all of the assets of these individuals and most of the assets of the Company are located outside the United
States. As a result, it may not be possible for you to enforce against AIXTRON judgments obtained in the United States. You may also encounter difficulties in connection with the enforcement in
Germany of liabilities based solely upon United States laws in original actions or in actions for the enforcement of judgments of United States courts.

You may have access to less information about AIXTRON and fewer opportunities to exercise your rights as a shareholder if you hold AIXTRON's ordinary shares through its
ADSs.

The rights and terms of AIXTRON's ADSs are designed to replicate, to the extent reasonably practicable, the rights applicable to the
Company's ordinary shares, for which there is no active trading market in the United States. However, because of aspects of German law, the Company's Articles of Association and the contractual terms
of the deposit agreement under which AIXTRON's ADSs are issued, your rights as a holder of ADSs will differ in various ways from a shareholder's rights, and you may be affected in other ways,
including:



11

---



Table of Contents



As a holder of AIXTRON's ADSs you may have fewer or less well-defined shareholders' rights compared to a holder of common stock of a U.S. company.

AIXTRON's corporate affairs are governed by its Articles of Association (Satzung) and German law. German law is generally less specific
than U.S. law in terms of governance of corporate operations. Under German law, as a holder of AIXTRON's ADSs you may have fewer or less well-defined rights than you would as a shareholder
of a U.S. company. For example, a shareholder of a U.S. corporation may institute lawsuits on behalf of the corporation and class actions. In Germany the company must assert claims for damages against
members of the Executive Board or the Supervisory Board upon a respective shareholders' resolution requiring a simple majority of the votes cast. Moreover, in Germany, shareholders whose shares
represent 1% or a proportional amount of EUR 100,000 of the stated share capital of the stock corporation may apply in court for authorization to assert claims for damages of the Company against
members of the Executive Board and/or the Supervisory Board in their own name. However, the Company may at any time assert its claims for damages on its own behalf; in such case any pending
authorization or court proceeding initiated by a shareholder of the Company related to the same claims for damages will then be inadmissible. As a result, a shareholder of a German stock corporation
may not be able to protect his or her interest in the shares as well as a shareholder of a U.S. corporation could.

AIXTRON may in the future be considered a passive foreign investment company.

The United States Internal Revenue Code contains special rules relating to passive foreign investment companies ("PFICs"). A United
States holder who owns stock in a PFIC is generally subject to adverse tax consequences under these rules. These rules do not apply to non-United States holders. A company is treated as a
PFIC if at least 75% of the company's gross income for a taxable year consists of "passive income," defined generally as income from passive investments, as opposed to operating income. A company is
also treated as a PFIC if the average percentage of the value of its assets, including cash balances that produce or are held for the production of passive income is at least 50%. While AIXTRON
believes it is currently not a PFIC, because a company's status as a PFIC is a complex, factual determination made on an annual basis,
there can be no assurance that the Company will not become a PFIC in the future. Further details about the PFIC rules and their consequences to United States holders can be found under "Item 10
Additional InformationTaxation."

If
AIXTRON was classified as a PFIC, unless a U.S. holder made a timely specific election, a special tax regime would apply to any "excess distribution," which would be such holder's
share of distributions in any year that are greater than 125% of the average annual distributions received by such holder in the three preceding years or such holder's holding period, if shorter; and
any gain realized on the sale or other disposition of the ADSs. Under this regime, any excess distribution and realized gain would be treated as ordinary income and would be subject to tax as if the
excess distribution or gain had been realized ratably over such holder's holding period for the ADSs. A U.S. holder will generally be required to pay taxes on the amount allocated to a year at the
highest marginal tax rate and pay interest on the prior year's taxes, unless such U.S. holder is able to ameliorate the tax consequences somewhat by making a mark-to-market
election or "QEF election". You should consult your tax advisor of the consequences of AIXTRON's classification as a PFIC.

Table of Contents

Because AIXTRON is not obligated to continue to have its ADSs listed on the NASDAQ Global Select Market, your ability to trade the ADSs may be eliminated in the future, and
the market prices of the Company's ADSs and ordinary shares may be negatively affected and it may become more difficult to sell the ordinary shares.

Because AIXTRON is not obligated to continue to have the ADSs listed on the NASDAQ Global Select Market, AIXTRON could delist its ADSs,
which could adversely affect the market price for the ADSs and ordinary shares. In addition, if the ADSs are no longer listed on the NASDAQ Global Select Market, there can be no assurance that a
market will develop for the ADSs and it will be more difficult for a United States holder to sell the underlying ordinary shares.

Identification of deficiencies or weaknesses in AIXTRON's internal control over financial reporting may have an adverse impact on the Company's financial condition and
results of operations and the trading price of its securities.

The Company's Management is required to prepare a report relating to its evaluation of the Company's internal control over financial
reporting, as required pursuant to Section 404 of the U.S. Sarbanes-Oxley Act of 2002 (the "Sarbanes-Oxley Act"). AIXTRON intends to take prompt measures to eliminate any identified
deficiencies or weaknesses in the Company's internal control structure. Such measures may involve significant effort and expense. Depending on the nature and extent of any identified deficiency or
weakness, AIXTRON could be required to restate previously issued financial statements. Any of such actions may have an adverse impact on the Company's financial condition and results of operations and
the trading price of its securities.

Item 4:    Information on the Company

A.    History and Development of the Company

Introduction

AIXTRON SE was incorporated as a German limited liability corporation in 1983 and converted to a stock corporation under the laws of
the Federal Republic of Germany in 1997. In 2010, AIXTRON converted from a German stock corporation ("Aktiengesellschaft" or "AG") to a stock corporation in the form of a European Company ("Societas
Europaea" or "SE"). As such, AIXTRON SE is subject not only to the German stock corporation law, but also to the superseding European SE regulations and the German SE Implementation Act
(SE-Ausführungsgesetz). As a result of such conversion, AIXTRON will continue to be treated to a large extent like a German stock corporation, including with respect to
capital measures, shareholders' meetings and accounting. AIXTRON is headquartered in Herzogenrath, Germany and has wholly-owned subsidiaries in the United Kingdom, China, Japan, South Korea, Sweden,
Taiwan and the United States. AIXTRON's principal executive office is located at Kaiserstrasse 98, D-52134 Herzogenrath, Germany, and the Company's telephone number there is
+49-241-8909-0. AIXTRON's agent for service of process in the United States is AIXTRON, Inc., 1139 Karlstad Drive, Sunnyvale, California 94089.

Important Events

AIXTRON China Ltd.

On January 31, 2011, the Company established a new subsidiary, AIXTRON China Ltd., in Shanghai, China. AIXTRON is now
able to directly recruit and employ local and foreign employees in China. This was previously managed through a Chinese Government employment agency. The new legal structure also makes potential
future plans to open AIXTRON China Ltd. branch offices easier to initiate and execute. AIXTRON will also be able to streamline the process and reduce the management of any local sourcing of
components, assemblies and spare parts in China. This structural change is part of the Company's strategy to prepare the organization for the substantial growth potential that the Chinese market
represents. This potential is evidenced by the increasing local momentum being focused on the key economic and developmental targets detailed in the 12th Chinese Five-Year Plan
(2011-2015), released in March, 2011. This latest extensive Government plan provides a strong national focus on energy efficiency, including LED lighting technologies.

AIXTRON
is constantly working on the improvement of existing technologies and products. In the course of the last three years, AIXTRON has introduced several new system generations and
technologies, such as the QXP-8300 silicon semiconductor technology, the G5 planetary reactor and the CRIUS® II-XL Close Coupled Showerhead® reactor
technology. For more information, please refer to item 5. "AIXTRON-specific Factors".

Research and Development

AIXTRON maintains a strong, well funded and focused R&D program within the business. The Company has a comprehensive R&D
infrastructure, which has been greatly extended by the new R&D center at the Company's headquarters in Herzogenrath. Through the numerous research projects AIXTRON is engaged in, and a highly skilled
R&D team of 318 employees (2010: 248; 2009: 206), the Company is focused on retaining its position as a leading provider of deposition equipment for the manufacturing of device
structures for the semiconductor industry.

In
addition to the new state-of-the-art R&D center in Herzogenrath, AIXTRON also operates R&D laboratories in Aachen (Germany), in Cambridge (United
Kingdom) and in Sunnyvale (United States). These in-house research laboratories are equipped with the latest version AIXTRON systems and are used for researching new equipment, materials
and processes for the production of semiconductor structures.

AIXTRON's
global R&D organization works as a technology matrix, with each project drawing on the expertise that resides within each center of excellence, regardless of location. The R&D
team also works closely with the global sales and service organization to develop systems, tailored to customers' individual needs. Much of the work done by the AIXTRON R&D team is also in conjunction
and collaboration with many well-known universities, external research centers and industrial partners worldwide, including many publicly and regionally funded development projects.

The
projects pursued in AIXTRON's R&D facilities are supported by cutting-edge simulation systems and techniques, which have been developed in-house, to become
critical tools in significantly shortening development times in addition to reducing material and energy-intensive manufacturing and testing processes to a minimum.

In 2011,
R&D expenditures increased year on year, in line with expectations, by € 4.3 million, from
€ 46.1 million in 2010 (2009: € 32.9 million) to € 50.4 million, reflecting
the Company's determination to further strengthen its technological positioning. For more information regarding R&D expenses from fiscal year 2009 through 2011, refer to Item 5.A
"Operating ResultsDevelopment of ResultsOperating Costs" in this report.

AIXTRON
plans to further increase R&D expenditures in 2012, underlining the commitment to remain a recognized technology and market leader. In the current compound semiconductor
market environment, with an increased number of market participants, especially in China and with shortening product cycle times, Management believes that focused and market-led R&D is a
critical success factor for AIXTRON. R&D activities include continual improvement programs, the delivery of more process capabilities, factory integration, increased automation and the development of
new system architectures, all of which are targeted at enabling customers, who are faced with increasing margin pressure, to achieve improvements in throughput efficiencies and total cost of
ownership.

Moreover,
the Company will continue to pursue new potential opportunities to leverage its core know how of material deposition into new market and technology areas beyond LEDs, as
evidenced by AIXTRON's many internally and externally funded research projects.

One
recent example is AIXTRON's participation in the EU funded "HiPoSwitch" joint research project, which started in the third quarter of 2011, and addresses the power electronics
market. Through a coordinated approach, the eight members of the research consortium are focused on the development of highly efficient Gallium Nitride (GaN) based power devices using Silicon as a
substrate material. This new development has the potential to significantly improve the device's energy efficiency as well as its functional and lifetime performance. The most promising potential for
GaN-on-Silicon power electronic devices is perceived to be in the fields of telecommunication, IT, consumer electronics, automotive and industrial applications.

Started
at the end of 2011, the German government funded "TeleGAN" joint research project also targets the power electronics industry; more specifically it aims to improve the
power supply efficiency in wireless telecommunication base stations. The group of six research partners including AIXTRON, is focused on the development of free standing (FS) 2 Inch
semi-isolating (SI) GaN substrates employing

AIXTRON's
proven HVPE technology, to enable next generation HFET (heterostructure field-effect transistors) devices for extreme high voltage and high frequency applications.

The
research project "PROTECT" (production technology for the encapsulation of organic electronics), funded by the German region of North Rhine-Westphalia, was approved and started in
the fourth quarter of 2011. It aims at the development of flexible organic electronic devices. Because of their potential energy and lighting efficiency, combined with potentially low material
costs, OLEDs are seen as important future lighting and display sources, supplementing LED technology. AIXTRON, together with Philips and two other research partners will work on enhanced methods to
create thin film barrier layers for a more cost efficient encapsulation technique for OLEDs. The project is ultimately focused on the development of new equipment concepts (cluster and
in-line solutions) for the pilot production of high performance OLEDs.

Intellectual Property

AIXTRON aims to secure its technology by patenting and protecting inventions and know-how, provided it is strategically
expedient and possible for the Company to do so. As of December 31, 2011, 198 patent-protected inventions were in use, of which 11 were registered in the reporting period. Patent protection for
these inventions applies in those sales markets relevant for AIXTRON, specifically in Europe, China, Japan, South Korea, Taiwan and the United States. These patents are maintained and renewed annually
and will expire between 2012 and 2031.

AIXTRON
also has exclusive and non-exclusive licenses to patents owned by others covering certain AIXTRON's products, as well as SAP Software licenses.

AIXTRON
is the licensee of certain patents owned by Centre National de la Recherche Scientifique and Universal Display Corporation which are important to the Company's operations in the
fields of AVD® and OVPD®. Under the terms of those licenses, AIXTRON sells epitaxial reactors that manage the layering of materials, produced by thin film deposition processes
that enable the high precision liquid injection, evaporation and gas phase deposition of metal organic materials required to produce photoelectric and electronic devices. Similar principles are
employed in the design of Organic Vapor Phase Deposition equipment for use in the manufacture of organic light emitting devices. Management finds it impractical to quantify the portion of revenues
attributable to
products that incorporate the technology governed by these agreements because all product sales can be aggregated into one group based upon the common technology.

Manufacturing

The AIXTRON Manufacturing operation is principally involved in the final assembly stage of production, including equipment
configuration, tuning and testing. The Company purchases all of the components and most of the assemblies required to manufacture the equipment from third-party contractors and suppliers. AIXTRON's
contractors and suppliers are carefully selected and qualified to be able to source, supply and/or partially assemble and test individual equipment parts and sub-assemblies. For strategic
reasons, there are typically several suppliers for each AIXTRON equipment component/assembly. However, AIXTRON single sources some key components for its systems and is therefore dependent on
contracts with the specific supplier of such components. AIXTRON's own staff manages the whole manufacturing process and in conjunction with in-house contractors executes the final
manufacturing steps as described above.

Since 1994,
AIXTRON has been assessed annually and awarded unlimited ISO 9001 certification. In 2003, the process-oriented management system was successfully
certified in accordance with worldwide quality standard DIN EN ISO 9001:2000. In October 2009, this certification was upgraded to DIN EN ISO 9001:2008.

The
Company routinely complies with all applicable international standards and procedures for the equipment industry. The "CE" label qualification confirms the conformity of AIXTRON
products with the applicable European directives and standards. Moreover, the "UL" standard for product admission to the US market and the recommended requirements of the SEMI
organization are also complied with. When developing new equipment, the "Restriction of Hazardous Substances Directive, RoHS" is strictly adhered to, as are the internal compliance requirements to
meet these specific rules and standards. Several independent certification companies, such as "TÜV" and "ETL" have also confirmed AIXTRON's compliance with their
requirements and specifications through the issuance of the respective examination certifications.

Marketing Channels

The Company markets and sells its products worldwide, principally through its own direct sales organization, but also through appointed
dealers and sales representatives. The relationships with these appointed sales and service representatives are generally terminable at the
Company's will. These arrangements typically require that AIXTRON reimburse the representatives for their business expenses as well as pay specified service rates or sales commissions, which vary by
geographic region.

AIXTRON's
own Sales and Service Organization provides a full range of customer services, from the initial support of the customized development of an AIXTRON system, through to the final
installation and ongoing customer training as well as operational support of its systems.

Customers and Principal Markets

AIXTRON's semiconductor device customers are principally, but not exclusively, focused on the manufacturing of LEDs, wireless device,
power electronics, optoelectronics, logic and data storage components. Some of these customers are vertically integrated device manufacturers who serve the entire value chain down to the end consumer.
Others are independent component suppliers who deliver chips and components produced on AIXTRON equipment to the next link in the value chain, namely, the electronic device manufacturers. The
Company's customers also include research centers and universities. Most of the world's leading electronic device manufacturers produce in Asia and consequently, the majority of AIXTRON sales continue
to be delivered into this region.

No
single AIXTRON customer represented more than 10% of total revenues in 2011.

For
more information regarding a breakdown of revenues by technology and region for each of the last three fiscal years, refer to Item 5.A. "Operating and Financial Review and
ProspectsOperating ResultsDevelopment of Revenues" in this report.

Seasonality

AIXTRON's business is currently not materially affected by seasonality.

Competitive Positioning

Historically, AIXTRON's main competitor in MOCVD applications has been Veeco Instruments Inc. (USA) with part of its
"LED & Solar" business segment. AIXTRON also competes with a number of Asian manufacturers including Taiyo Nippon Sanso (Japan), amongst
others. As a consequence of the rising LED end-market expectations and positive prospects for MOCVD equipment demand, there is evidence that equipment companies from adjacent industries
continue to attempt to qualify their own MOCVD tools with customers. For example; both Applied Materials Inc. (USA) and Jusung Engineering Co. Ltd. (South Korea) are known to be
in the development process for an in-house equipment solution for the production of LEDs. Some local Chinese companies have also commenced MOCVD equipment design and manufacturing plans
supported by government initiatives.

Based
on the latest published market share research by Gartner Dataquest (March 2011), it was estimated that the share of the worldwide MOCVD equipment market
(estimated 2010 total market value: USD 1.7bn) held by AIXTRON in 2010 was around 56%. In the same report, the Company's strongest competitor in terms of sales, Veeco
Instruments Inc., had an estimated market share of approximately 39%. Viewed in the mid to long term, AIXTRON continues to target a market leading position in the global MOCVD market. In a more
recent report (December 2011) Gartner Dataquest anticipated that the total value of the 2011 MOCVD equipment market would decrease to approximately USD 1.5 billion.

For
emerging Organic Semiconductor applications, AIXTRON competes with established manufacturers such as Ulvac, Inc. (Japan), Tokki Corporation (Japan), Sumitomo (Japan), Applied
Materials, Inc. (USA), Doosan DND Co. Ltd. (South Korea), Sunic System (South Korea) and a number of other smaller companies. While these competitors use established vacuum
thermal evaporation ("VTE") technology or polymer technology to produce organic light emitting diodes (OLEDs), AIXTRON offers OLED manufacturers its own highly innovative organic vapor phase
deposition (OVPD®) and PVPD (polymer vapor phase deposition) large area deposition technologies. In AIXTRON's opinion, due to a perceived superior process technology and the
potential for reducing manufacturing costs, these technologies have the potential to compete successfully with VTE and polymer technologies. AIXTRON is well positioned as a potential deposition system
supplier for next generation OLEDs and large area deposition applications that are anticipated to be used in innovative,

self-luminous
displays as well as future potential lighting, solar cell, and other electronic OLED applications.

As
AIXTRON's system technology and customer applications are still in the market entry phase, Organic Semiconductor market share information is neither available nor meaningful at this
point in time.

For
CVD, AVD® and ALD applications, AIXTRON competes with a variety of other equipment companies, including Applied Materials, Inc. (USA), Tokyo Electron Ltd.
(Japan), ASM International N.V. (Netherlands), IPS Technology (South Korea), Jusung Engineering Co. Ltd. (South Korea), and Hitachi Kokusai Electric Co. Inc.
(Japan). With the Company's currently available silicon semiconductor manufacturing technologies, AIXTRON is potentially well positioned to offer advanced films for 28nm node and beyond for memory and
logic integrated circuits (ICs). These technologies enable extremely high precision in depositing very thin material layers and facilitate the consistent coating of complex three-dimensional
microelectronic device structures. Moreover, they offer the
semiconductor industry new material coating possibilities for the next generation of computer chips and devices, and, in AIXTRON's opinion, present high development potential for the future.

The
specific market niche to be addressed by AIXTRON's system technologies for the production of specialized applications such as gate stacks and capacitors was estimated by Gartner
Dataquest in December 2011 to be valued at USD 378 million for 2011. In line with other capital equipment companies positioning for 28nm node and beyond for memory and
logic integrated circuits, AIXTRON has continued to experience low order intake and revenue levels in 2011. AIXTRON's market share in this area is therefore not considered meaningful at this
point in time.

For
more information regarding a breakdown of revenues by technology and region for each of the last three fiscal years, refer to Item 5.A. "Operating and Financial Review and
ProspectsOperating ResultsDevelopment of Revenues" in this report.

Key Performance Indicators

The Executive Board has implemented numerous control systems and procedures to manage, monitor, analyze, and document Company risks and
opportunities, including a Key Performance Indicator system addressing relevant business areas, with a primary focus on the "Market", "Finance" and "Technology Development" control areas.

In
the "Market" control area, using third party reports and direct customer dialog, AIXTRON pursues a market-led product development strategy through the careful examination
of market trends and customer requirements. The objective of this strategy is to ensure the market availability of new and appropriately competitive product generations in line with customer
requirements.

In
the "Finance" control area, the Executive Board uses a range of internal and external key performance indicators, with particular focus on: total sales, contribution margins, net
result data and cash flow. The objective of these controls is to ensure that profitable revenue growth is matched by appropriate and prudent cash flow development.

In
the "Technology Development" control area, the Executive Board uses a range of internal and external key performance indicators to evaluate the progress and success of internal
projects. The Management regularly reviews project progress against target timelines and objectives, including: total sales revenue and net result data comparisons to the original targets. The
objective of this review process is to ensure that ongoing projects retain the necessary level of technological and commercial competitiveness throughout the life of the product.

Government Regulation

Due to the nature of AIXTRON's products, the shipment of some products to customers in certain countries requires the Company to obtain
an export license from legal and statutory authorities in Germany, the UK and the US, including, for example, the Bundesamt für Wirtschaft und Ausfuhrkontrolle, BAFA in Germany, the
Department for Business, Innovation and Skills in the UK as well as the Department of State and the Department of Commerce in the US.

Research
and development activities, as well as the manufacturing and demonstration of the Company's products involve the use of potentially harmful chemical and hazardous materials and
radioactive compounds and as a result, AIXTRON is subject to stringent environmental and safety regulations in connection with its business operations.

In 2011, AIXTRON has entered into a formal cooperation agreement with the Suzhou Institute of Nano-tech and Nano-bionics (SINANO)
to establish a new MOCVD training and demonstration facility in Suzhou/China to train Chinese customers and potential customers' engineers. The training center is equipped with AIXTRON's latest
generation MOCVD systems, the CRIUS® II-XL and the AIX G5 HT. The 2012 investment of approximately € 10 million into the MOCVD
training and demonstration facility will be funded out of operating cash flow and available cash resources. Out of the planned € 10 million investment,
€ 1.9 million have been invested by January 31, 2012.

The
new Research & Development ("R&D") center in Herzogenrath with an approximate size of 16,000 square meters and room for approximately 450 staff was fully
completed on budget and on time by the third quarter of 2010 (Phase I) and by the first quarter of 2012 (Phase II).

For
more information regarding the capital expenditures relating to the R&D building project, refer to Item 5.B. "Liquidity and Capital ResourcesInvestments" in this
report.

Environmental Issues

The research and development activities, as well as the manufacturing and demonstration of AIXTRON's products conducted in some of its
facilities, involve the use of potentially harmful chemical and other hazardous or potentially hazardous materials and radioactive compounds. Failure or inability to comply with existing or future
environmental regulations could result in significant remediation liabilities, the imposition of fines and/or the suspension or termination of production.

Environmental
protection and the responsible use of resources are an essential part of AIXTRON's business strategy. The Company's engineers work diligently to continuously improve
AIXTRON's systems, both in terms of resource conservation and environmentally-friendly design and function.

Item 4A:    Unresolved Staff Comments

None.

Item 5:    Operating and Financial Review and Prospects

The Semiconductor Equipment Market

While the recorded world real gross domestic product in 2011 increased in value terms by an estimated 3.8% (according to the World
Economic Outlook, published by the International Monetary Fund ("IMF"), the electronics equipment industry increased by 6% (according to Gartner Dataquest, December 2011).

In
comparison, semiconductor capital spending showed a growth of about 14% in 2011, and specific spending on Wafer Front End equipment (WFE), which includes spending on deposition tools
supplied by AIXTRON, increased by 10% year on year (according to Gartner Dataquest, December 2011).

The HB LED Market

In 2011, AIXTRON generated the large majority, i.e. more than 83% (2010: 93%; 2009: 81%), of its total equipment revenues, with
the sale of High Brightness ("HB") LED manufacturing systems.

The
customer end-market for High Brightness ("HB") LEDs, which can be produced with AIXTRON's compound semiconductor equipment, was predicted by Strategies Unlimited (an
independent semiconductor market research institute) in their October 2011 report, to grow in 2011 by 10% to USD 12.3 billion (2010: USD 11.2 billion). During the same
time, sales of LED units are expected to grow by 34%. However, LED prices have dropped by 20-40% throughout the year mainly due to excess capacity and a slowdown in demand for TVs by
consumers.

A
combination of the market-driven LED price decline described above and a variety of governmental and commercial industry initiatives, helped by a rising public awareness of the
positive environmental benefits of LED technology are perceived to be positive contributions towards the early adoption of LED general lighting applications.

Towards
the end of 2009, Chinese local government authorities started to support LED makers through substantial direct subsidies in order to build up a significant Chinese production
industry aimed

22

Table of Contents

at
LED lighting applications. In addition to these subsidies, the Chinese Five Year Plan, published in March 2011, reiterated China's commitment to support the development of this industry and
consequently their aspirations to become a meaningful global player in this market. Towards the end of 2011, although increased credit tightness appeared to suppress the availability of local
government funding, market rumors suggest that subsidies previously aimed exclusively at fixed assets could potentially become available to stimulate the end market demand for LED lighting.

In
June 2011, South Korea launched a new LED lighting adoption program as part of the South Korean government's national energy-saving objectives. The program aims at achieving 100%
adoption rates for LED lighting in South Korean governmental institutions and 60% penetration of all lighting applications throughout the country by 2020. Currently, LEDs account for only 2.5% of all
lighting in South Korea.

An
increased number of governments around the world (e.g. EU countries, Russia, Japan, China, South Korea, Taiwan, Australia, USA, and Canada) are pursuing measures to phase out
incandescent light
bulbs for general lighting. The intent of these programs is to encourage the use and further technological development of more energy-efficient lighting alternatives including LED lighting.

Two
influential global consumer electronics companies in South Korea are already offering LED light bulbs equivalent to a 60W incandescent light in their own domestic market at prices
around USD 16-18, which is, in the opinion of AIXTRON Management, within the potential key price tipping point range for commercial LED light adoption and represents a 50% year on
year market price reduction.

AIXTRON-specific Factors

Successful market introduction of new products

During 2011, AIXTRON experienced strong market acceptance of its latest generation G5 and CRIUS® II equipment systems,
first launched in 2010, and finished the year 2011 representing 48% of AIXTRON's 2011 equipment revenues (2010: 26%).

In
July and November 2011, AIXTRON has launched enhanced versions of its CRIUS® II MOCVD system, the CRIUS® II-L and the CRIUS®
II-XL. Based on the production proven Showerhead reactor design of the CRIUS® II, the latest systems have an increased reactor capacity of 19x4 inch wafers per production run,
thus providing LED manufacturers with low cost of ownership and optimized footprint efficiency enabling a faster reduction in unit LED chip cost.

AIXTRON
has received positive customer response to such production systems and leading customers have already taken delivery supporting Management's confidence in the mid- to
long-term growth perspectives of the LED lighting industry and AIXTRON's contribution to that growth.

Focused China strategy

Whilst the vast majority of AIXTRON's revenues traditionally come from Asia (90% in 2011; 91% in 2010; 82% in 2009), significant shifts
between the different Asian revenue regions have taken place, with China having been the Company's strongest regional revenue driver in
2011. AIXTRON believes that the Chinese region still offers substantial growth potential for the LED market supported by the respective key economic and developmental targets detailed in the
12th Chinese Five-Year Plan released in March 2011.

To
implement its focused China strategy, AIXTRON established a new wholly-owned subsidiary, AIXTRON China Ltd., in Shanghai, China in 2011. This new business structure will make
it easier for AIXTRON to improve the infrastructure required to support AIXTRON's Chinese customer base, including the opening of further offices if necessary, and thereby supplying spare parts and
services faster and more efficiently in the future.

In
June 2011, AIXTRON also signed a formal collaboration agreement with the Suzhou Institute of Nano-Tech and Nano-Bionics (SINANO) to open a new MOCVD training
and demonstration center in Suzhou, China. The new training center is equipped with AIXTRON's latest generation MOCVD systems, and is staffed with a professional team of highly experienced AIXTRON
process and service engineers. The agreement is designed to both support SINANO's research work and to train Chinese MOCVD engineers and operators.

Decreasing order intake and revenues in the second half of 2011

In the second half of the year, the previously high investment and purchase order activities by Asian LED manufacturers, driven by the
relatively easy availability of government funding, abruptly slowed down. This was partially a consequence of the perceived lack of sufficiently developed end-market demand, but also
evidence of some relevant financing pressures on certain Asian LED manufacturers, including both sovereign and bank suppression of credit lines and bank loans.

The
degree to which orders slowed down in the second half can be seen in comparison with the first half order intake; H1/2011: € 432.5 million; H2/2011:
€ 80.9 million. A similar effect can be seen with the revenues; H1/2011: € 381.0 million; H2/2011: € 229.9
million.

From
August 2011, AIXTRON began to receive increased requests for delivery deferrals, which subsequently led to a Management decision to reduce the order backlog position by
€ 100 million. The year-end order backlog stood at € 141.0 million on December 31, 2011 (December 31,
2010: 274.8 million).

Year-end
inventories increased by 10% to € 184.6 million (December 31, 2010: € 167.2 million),
largely due to the indeterminately deferred
deliveries referred to above. However, due to the highly modular design of AIXTRON's common platform equipment, these deferred work-in-progress systems can be reconfigured to
meet the requirements of new order requests.

The
immediate market outlook for our specific industry, i.e. the first half of the year, suggests a continuation of the low level market activity seen towards the end of 2011.

In
view of this and the consequent likely reduction in inventory turnover, combined with new product developments in the pipeline, Management decided to make a provision against the
potential risk of unsold excess inventories of approximately € 40 million, resulting in the year end total inventories mentioned above.

Because
of its flexible business model, including flexible workforce agreements, AIXTRON was able to adapt to the deteriorating business environment during the second half of the year,
and was able to deliver a gross margin of 38% for 2011 (2010: 53%; 2009: 44%) and an operating margin of 18% (2010: 35%; 2009: 21%).

Management Assessment of Company Situation

Despite the backdrop of a very challenging macro-economic environment, AIXTRON still delivered strong revenues in the first half of the
year, mainly driven by demand from LED backlighting, early lighting applications, and a continuation of the generous regional subsidies in China.

Progressively
through the course of the year, Asian LED customers have had to face the effects of lower consumer demand for LED backlit TVs and monitors, contributing to overcapacity for
LED manufacturers, causing evident margin pressures for Asian LED customers due to LED price declines. Many new LED customers were additionally facing problems in putting in place the necessary
infrastructure and expertise to support their business plans.

These
specific factors, amongst others, led to the very abrupt slow down in demand for our systems in the third quarter, particularly in Asia, and resulted in the AIXTRON Management
reviewing its business outlook, and consequently the original guidance given for fiscal year 2011.

Management
also reviewed the equipment order backlog and reduced the previously published order backlog of € 373.5 million by
€ 100.0 million. The conclusion of this review took into account AIXTRON Management's opinion on backlog conversion risk, purchase order delays and deferred system
delivery requests by several customers, specifically in Asia.

The
immediate market outlook for our specific industry i.e. the first half of the year, suggests a continuation of the low level market activity seen towards the end of 2011.

In
view of this and the consequent likely reduction in inventory turnover, combined with new product developments in the pipeline, Management decided to make a provision against the
potential risk of unsold excess inventories of approximately € 40 million, resulting in the year end total inventories mentioned above.

However,
the 2011 full year result still underlines the benefit of the Company's flexible business model and stable financial position which enabled Management to effectively cope with
these severe

market
fluctuations, while maintaining their commitment to strategic investments in research and development.

AIXTRON
Management continues to monitor very carefully the developments in the global economy and financial markets, and regularly examines what can be potentially done to mitigate
possible negative consequential effects on AIXTRON's business.

A.    Operating Results: 2009-2011

In fiscal year 2011, AIXTRON recorded revenues of € 611.0 million, a decrease of
€ 172.8 million, or 22%, compared to € 783.8 million in 2010 (2009: € 302.9 million). This
decrease was principally due to the rapid deterioration in the business environment during the second half of the
year where revenues were down 40% compared to the first half year. In 2010, the exceptionally positive revenue development had been largely influenced by substantial demand from Asian customers
serving a growth market for LED TVs at that time and government subsidy support. In 2010, revenues also benefited from a stronger USD/EUR exchange rate.

The
decrease in full year 2011 revenues was mainly attributable to the 26% reduction in the Company's deposition equipment revenues (2011:
€ 556.3 million; 2010: € 735.7 million; 2009: € 275.0 million). The increase in 2010
compared to 2009 full year revenues was mainly driven by the 168% year on year increase in the Company's deposition equipment revenues. The equipment bought by AIXTRON's customers is predominantly
used for the production of LEDs, which in turn are primarily employed as backlighting devices for LCD displays and emerging lighting applications.

Total
equipment sales generated 91% of total revenues in 2011 (94% in 2010; 91% in 2009). The remaining revenues were generated by sales of spare parts and service, which at 9% in 2011
were 3 percentage points higher relative to total revenues than in 2010 (6% in 2010; 9% in 2009) (2011: € 54.7 million; 2010:
€ 48.1 million; 2009: € 27.9 million). The revenue development from spares and service typically lags the revenue development
from equipment, since such services and parts are typically included or covered by warranty provided to customers in the after sales period. The revenues from spare parts and service in 2010 increased
by 72% compared to 2009. These increases reflected the prior year increases in equipment sales because such revenues typically lag behind the revenue development from equipment, since services and
parts are typically included or covered by warranty provided to customers in the after sales period.

The
decrease of total equipment sales in 2011 was principally due to the rapid deterioration in the business environment during the second half of the year as described above. In 2010,
the exceptionally positive revenue development had been largely influenced by substantial demand from Asian customers serving a growth market for LED TVs at that time and government subsidy support.

A very high percentage, namely 90% of total revenues in 2011, was generated by sales to customers in Asia, which is 1 percentage point
lower than the 91% recorded in 2010 (82% in 2009). 4% of revenues in 2011 were generated in Europe (4% in 2010; 14% in 2009) and the remaining 6% in

the
USA (5% in 2010; 4% in 2009). The high European revenue share in 2009 was mainly due to the revenue recorded in connection with sales to one major customer in the first quarter of 2009.

Cost of Sales

Cost of sales increased year on year by 2% from € 372.0 million in 2010 (2009:
€ 168.1 million) to
€ 379.6 million in 2011, while cost of sales relative to revenues were up 15 percentage points to 62% from 47% in 2010 (55% in 2009). The relatively high
absolute cost base is mainly due to the above mentioned write-down of inventories in combination with the increasing sales volume effect in the first half of the year, accounting for more than 50% of
total cost of sales. The strong increase relative to revenues is attributable to the above mentioned write-down of inventories combined with the reduced full year sales volume as well as a less
favorable product and pricing mix compared to the year 2010. The year on year cost of sales improvement in 2010 was mainly due to the increasing sales volume effect and a more favorable product mix
than in 2009.

Gross Profit, Gross Margin

While revenues decreased by 22% and cost of sales increased by 2%, the Company's gross profit decreased by 44% year on year to
€ 231.4 million in 2011 (2010: € 411.8 million; 2009: € 134.7 million), resulting in a
15 percentage points lower gross margin of 38% after 53% in 2010 (45% in 2009). 7 percentage points of this year-on-year decline is attributable to the
€ 40 million inventory write-down.

Operating Costs

Operating costs decreased year on year by 13% to € 118.5 million in 2011 (2010:
€ 136.2 million; 2009: € 72.0 million). Operating costs relative to revenues were 19% in 2011, 2 percentage points higher
than the 17% in 2010 (24% in 2009). In 2010, operating costs relative to revenues decreased by 7 percentage points. This development was influenced by the following factors:

Selling
expenses decreased year on year by 34% to € 32.1 million (2010: € 48.9 million; 2009:
€ 25.5 million), which is mainly due to lower sales commissions resulting from the change in the geographical mix of sales, and lower warranty expenses. In contrast
to that, the increase in sales expenses in 2010 was mainly attributable to higher warranty expenses in consequence of higher volume and sales commissions, which vary by territory, partially offset by
disproportionally lower increases in discretionary expenses. Selling expenses relative to revenues also decreased year on year from 6% in 2010 by 1 percentage point to 5% in 2011 (8% in 2009).

The
year on year 13% increase in general and administration expenses to € 34.0 million in 2011 (2010:
€ 30.1 million; 2009: € 21.3 million) was principally due to the increased number of employees

26

within
this area, as well as higher IT infrastructure and consultancy costs. The 2010 increase in absolute terms was principally due to profit-related variable administration expenses, IT
infrastructure costs and consultancy. General and administration expenses, relative to revenues, increased from 4% in 2010 (2009: 7%) by 2 percentage points to 6% in 2011, principally due to
the lower sales volume effect in connection with a higher absolute cost base. In 2010 general and administration expenses relative to revenues decreased by 3 percentage points, principally due
to the higher sales volume effect.

Research and development expenses increased by 9% year on year from € 46.1 million recorded in 2010 (2009:
€ 32.9 million) to € 50.4 million in 2011, due to further expansion of the development activities, including additional
personnel and material expenses. These activities are based on the necessity of an intensive R&D engagement to secure the Company's technology leading position. The 2010 increase in R&D expenses was
attributable to the increase in development activities, including additional personnel, material expenses and depreciation. In relative terms, R&D costs increased from 6% of revenues in 2010 (11% in
2009) to 8% in 2011, partially due to the reduced revenue base.

With the average number of Group employees increasing in line with the higher business volume in the first half of 2011, personnel expenses
increased by 10% in total from € 70.0 million in 2010 (2009: € 51.7 million) to
€ 76.6 million in 2011, and was up as a percentage of sales from 9% in 2010 (17% in 2009) to 13% in 2011.

2011
net other operating income and expenses resulted in an expense of € 2.0 million, compared to an expense of
€ 11.1 million in 2010 (2009: income of € 7.7 million), mainly due to the impact from currency effects. For comparison purposes
it should be noted that in 2009, net other operating income and expenses increased mainly due to the gains made from the sale of the Aachen office building of
€ 1.3 million recorded in the first quarter, customer compensation payments of € 3.5 million for cancelled orders, an increase
of € 1.4 million in R&D grants, a decrease of € 1.1 million in impaired receivables, and a reduction of
€ 5.6 million in negative foreign exchange effects, all of which had a positive influence.

In
2011, a net currency expense of € 2.1 million (2010: € 17.2 million; 2009: 1.4 million) was incurred
largely from USD/EUR hedging contracts. Income of € 1.6 million relates to hedge contracts. Expenses of € 3.7 million were
recorded from transactional and translation differences which do not involve hedge contracts. In 2010, expenses of € 20.8 million relate to hedge contracts,
including premiums on option contracts. A gain of € 3.6 million was recorded in 2010 from transactional and translation differences which do not involve hedge
contracts. In 2009, a loss of € 1.7 million was recorded, mainly resulting from transactional and translation differences which do not involve hedge contracts.

€ 1.4 million
of R&D grants, received in 2011 (2010: € 3.5 million; 2009: 3.3 million), were recorded as
other operating income.

Operating Result

The operating result decreased by 59% from € 275.5 million in 2010 (2009:
€ 62.7 million) to € 112.9 million in 2011, with a 17 percentage points lower operating margin of 18% (35% in 2010; 21%
in 2009). This development is a result of the aforementioned development of the Company's full year revenues and the relatively higher cost base including the write-down of inventories as described
above. In 2010, the operating result showed a strong improvement, in absolute and relative terms, due to the positive effects of an increase in revenues and relatively lower costs compared to 2009,
while the expense from currency hedges and currency translation effects offset, to a limited extent, some of the positive effects on the operating result and margin in 2010.

Profit/Loss Attributable to the Equity holders of AIXTRON SE (after taxes)

The 2011 after-tax profit attributable to the equity holders of the AIXTRON SE was
€ 79.5 million (13% of revenues), 59% down from the € 192.5 million (25% of revenues) in 2010 (2009:
€ 44.8 million or 15% of revenues).

Net Income AIXTRON SEUse of Results

AIXTRON SE, the parent company of the AIXTRON Group, recorded a net accumulated income in accordance with German generally accepted
accounting principles, (German GAAP) based on the German Commercial Code, HGB, of € 77.0 million for 2011 (2010:
€ 124.9 million; 2009: € 42.5 million).

AIXTRON's
Executive and Supervisory Boards will propose to the shareholders' meeting that a dividend of € 25.4 million or
€ 0.25 per share (€ 60.7 million or € 0.60 in 2010; € 15.1 million or
€ 0.15 per share for 2009) will be distributed for the fiscal year 2011.

Equipment Order Intake

In 2011, equipment order intake was 31% down year on year, at € 513.4 million (2010:
€ 748.3 million; 2009: € 370.1 million). The 2011 total order intake includes € 100 million
which was subsequently removed from the order backlog on September 15, 2011. As a matter of internal policy, order intake in US Dollars was recorded at a budget exchange rate for 2011, which
had been set at 1.35 USD/EUR at the beginning of the year (2010: 1.50 USD/EUR; 2009: 1.40 USD/EUR). In the second half of the year, the previously high investment and purchase
order activities by Asian LED manufacturers, driven by the relatively easy availability of government funding, abruptly slowed down. This was partially a consequence of the perceived lack of
sufficiently developed end-market demand, but also evidence of some relevant financing pressures on certain Asian LED manufacturers, including both sovereign and bank suppression of credit
lines and bank loans. As with revenue development; equipment order intake significantly increased in 2010 and was 102% up year on year, at € 748.3 million (2009:
€ 370.1 million).

Equipment Order Backlog

The total equipment order backlog of € 141.0 million at December 31, 2011 was 49% lower than
at the same point in time in 2010 (2010: € 274.8 million; 2009: € 203.8 million). The order backlog as of December 31,
2011 is post the adjustment made on September 15, 2011. As of year-end 2011, US Dollar denominated order backlog was recorded at a 2011 budget exchange rate, which had been set at
1.35 USD/EUR at the beginning of the year (2010: 1.50 USD/EUR; 2009: 1.40 USD/EUR). This order backlog was revalued at the 2012 budget rate of 1.40 USD/EUR as per
January 1, 2012, leading to an opening equipment order backlog of € 136.8 million.

As
a matter of strict internal policy of prudence, AIXTRON follows clear internal requirements before recording and reporting received equipment orders as order intake and order backlog.
These requirements comprise of all of the following minimum criteria:



In
addition and reflecting current market conditions; even if an order does fulfill all of the above criteria, the Company's Management reserves the right to assess whether the actual
realization of each respective system order is sufficiently likely to occur in a timely manner according to Management's opinion. When Management concludes, that there is an unacceptable degree of
risk of not realizing revenue on any specific system, Management will, until that risk is considered acceptable, exclude the order, or a portion of the order, from the recorded order intake and order
backlog figures, regardless of compliance with requirements of the points 1-4 above.

Currency Fluctuation

Fluctuations between the value of the Euro and other major currencies, in particular the US-Dollar and the Pound Sterling
can affect the Company's operating results. The Company enters into a variety of derivative financial instruments to manage approximately 50 to 90% of its exposure to foreign currency risk. See
"Item 11Quantitative and Qualitative Disclosure about Market Risk" for further details. Please also see "Item 3DRisk Factors" for further details.

B.    Liquidity and Capital Resources

Corporate Financial Management

AIXTRON has a central financial management system to control its global liquidity, interest and currency management.

Due
to the potentially volatile nature of its business, a sufficient level of cash is essential to expeditiously finance potential business needs. The Company's need for cash is
generally provided for, through operating cash flows and, to a smaller extent, through grants. In order to secure growth financing and support an acceleration and expansion of the R&D activities, the
Company has access to a strong equity capital base. Furthermore, approved by the Shareholders' Meeting, and subject to Supervisory Board approval, the Company has the authority to issue equity
instruments to be able to raise additional liquidity on the capital market if required.

AIXTRON
conducts a large part of its business in foreign currencies, i.e. in currencies other than the Euro. The most prevalent foreign currency relevant to AIXTRON is the US
Dollar. In order to hedge foreign exchange risks, the Company routinely employs currency hedging instruments. With these instruments, expected cash flows from customer orders and expected customer
orders are hedged.

Funding

The stated share capital (Grundkapital) of AIXTRON SE as of December 31, 2011 amounted to
€ 101,789,527 (December 31, 2010: € 101,179,866; December 31, 2009: € 100,667,177) divided into
101,789,527 registered shares with a proportional interest in the share capital of € 1.00 per no-par value registered share. Each no-par value
share represents the proportionate share in AIXTRON's stated share capital and carries one vote at the Company's annual shareholders' meeting. All registered shares

Table of Contents

are
fully paid in. The Company has issued a share certificate representing multiples of shares (global share); shareholders do not have the right to the issue of a share certificate representing their
share(s). There are no voting or transfer restrictions on AIXTRON's registered shares that are related to the Company's Articles of Association. There are no classes of securities endowed with special
control rights, nor are there any provisions for control of voting rights, if employees participate in the share capital without directly exercising their voting rights.

The
Company has a number of stock option programs in place that grant the members of the Executive Board and employees the right to purchase AIXTRON shares or American Depositary Shares
("ADS") under certain conditions. In fiscal year 2011, 609,661 stock options (2010: 513,014 options; 2009: 915,662 options) were exercised, resulting in delivery of in total 609,661 ordinary shares.
Under the 2011 tranche of the AIXTRON stock option plan 2007, 14,000 new stock options were granted in fiscal year 2011 (2010 tranche: 779,950 grants; 2009 tranche: 778,850 grants).

For
a more detailed description of the different stock option plans and a summary of all the stock option transactions, refer to Item 18 "Financial
StatementsNote 23. Share-based payment".

The
Company recorded no bank borrowings as of December 31, 2011, 2010 and 2009.

Where
necessary, AIXTRON SE provides loans and financial security facilities to its subsidiaries to enable the businesses to continue to operate efficiently. The Company has granted no
security interests in its own land and buildings.

The
equity ratio increased to 81% as of December 31, 2011, compared to 73% as of December 31, 2010 (December 31, 2009: 72%), with a 6% lower balance sheet total in
2011 compared to 2010 (+44% in 2010 compared to 2009). The high equity ratio in 2011 was mainly reached due to the € 38.8 million increase in retained earnings. In
2010, the total shareholders' equity
relative to total assets ratio was influenced by the strong profit related increase in equity and the significantly higher balance sheet total.

In
2011, the return on equity (ROE) based on the lower 2011 Group's net profit in proportion to the average total shareholders' equity at the start and end of the year was 13% (2010:
38%; 2009: 14%).

In
order to support future developments, the Company regularly explores and assesses on an ongoing basis, potential funding opportunities available in the market. Additional funding
needs could

(2010: € 51.9 million; 2009: € 9.8 million). In 2011, € 27.2 million (2010:
€ 48.6 million; 2009: € 8.8 million) were related to property, plant and equipment (including testing and laboratory equipment).
Thereof, € 16.7 million related to investments in the R&D center in Germany (Phase II), whereas in 2010, € 39.5 million
had been invested into the R&D center (Phases I and II) under construction at that time. € 11.6 million had been invested into Phase I for the
modular designed office building of the new R&D center. Another € 27.9 million had been invested into Phase II as assets under construction for the new
prototyping factory and laboratories that has been completed in early 2012. Investments of approximately € 10 million in the MOCVD training and demonstration
facility in Suzhou/China commenced in 2011 and will be completed in 2012.

Table of Contents

As in 2010, the remaining € 3.0 million (2010: € 3.3 million; 2009:
€ 1.0 million) were related to intangible assets including software licenses.

Almost
the entire capital expenditures (88%) for the year 2011 (2010: 94%; 2009: 77%) were invested in Germany and such expenditures for 2012 are also generally expected to be invested
primarily in Germany.

The
decrease of € 80.3 million in bank deposits with a maturity of at least three months in 2011 was recorded as cash inflow from investing
activities. In 2010, € 113.6 million of additional bank deposits was recorded as cash outflow from investing activities (2009:
€ 87.0 million).

All
2011, 2010 and 2009 expenditures were funded out of operating cash flow and available cash resources.

Capital
commitments are disclosed in Item 18 "Financial StatementsNote 28. Capital commitments" and are expected to be funded out of available cash resources.

Cash Flow

A cash outflow from operating activities of € 6.3 million (2010: cash inflow of
€ 147.7 million; 2009: cash inflow of € 78.9 million) was recorded in 2011. The decrease in operating cash flow in 2011 was
mainly caused by decreased profits of € 79.5 million (2010; € 192.5 million; 2009:
€ 44.8 million). Increased working capital requirements resulting from the increased business, were the main cause of the difference between the profit and cash
flow from operating activities for the years 2010 and 2009. In 2011, for some of the reasons stated above, the working capital increased in a decreasing business environment, which is the main reason
for the comparably high difference between the profit and the operating cash flow for the year.

A
cash inflow of € 50.5 million was recorded from investment activities in 2011 (2010: cash outflow of
€ 165.4 million; 2009: cash outflow of € 90.1 million). Money market deposits were liquidated in the amount of
€ 80.5 million (2010: investment of 113.6 million; 2009: investment of 87.0 million), which were previously classified as "other financial assets". In
2011, capital expenditure amounted to € 30.4 million (2010: € 51.9 million) mainly on the new R & D facilities in
Herzogenrath, Germany. In 2009 capital expenditure amounted to € 9.8 million where the net investment in capital equipment was reduced by disposal proceeds, mainly
from the sale of the former headquarters in Aachen.

A
cash outflow from financing activities of € 57.5 million (2010: cash outflow of € 11.6 million; 2009: cash
inflow on € 153.6 million) includes the dividend payments to shareholders of € 60.7 million (2010:
€ 15.1 million; 2009: € 8.2 million) and cash received from the issue of new shares of
€ 3.2 million (2010: € 3.5 million; 2009: 161.7 million). Cash outflow from financing activities in 2010 includes the
dividend payments to shareholders of € 15.1 million, which was partially offset by cash received from the issue of new shares totaling
€ 3.5 million.

Cash
and cash equivalents, including bank deposits with a maturity of at least three months, most of which is held in Euros (for more information, refer to "Investments"
above), decreased by 23% to € 295.2 million
(€ 172.9 million + € 122.3 million financial assets) as of December 31, 2011 (December 31, 2010:
€ 182.1 million + € 202.6 million financial assets; December 31, 2009:
€ 211.2 million + € 90.0 million financial assets).

Specific
proceeds that increased the 2011 year end liquidity position came, amongst other factors, from the 2011 net profit (€ 79.5 million)
and stock option exercises (€ 3.2 million), but in total were lower than the dividend payment (€ 60.7 million), reduced advance
payments from customers, higher inventories, and the above mentioned capital expenditures.

Specific
proceeds that increased the 2010 year end liquidity position came from, amongst other factors, the 2010 net profit (€ 192.5 million),
an increase of advanced payments of customers (€ 28.8 million), stock option exercises (€ 3.5 million), and in total, were
greater than the Q2/2010 dividend payment (€ 15.1 million), higher inventories, higher trade receivables, and the above mentioned capital expenditures.

There
are currently no material restrictions on the Company's use of cash resources.

Assessment of Liquidity and Capital Resources

The Company's liquidity is affected by many factors, some of which are related to its ongoing operations and others which are related
to the nature of the semiconductor equipment industry and to the economics of the countries in which the Company operates. Although the cash requirements fluctuate based on the timing and extent of
these factors, the Company believes that the liquidity provided by operating cash flows, grants, existing cash resources and financing arrangements, is sufficient to fund working capital, capital
expenditures and other ongoing business requirements. In a market and economic environment currently experienced by AIXTRON characterized by lower customer demand for the Company's products and
services, cash generated by operations could be lower than forecasted and not be sufficient. In such a situation, the Company might need to pursue obtaining short-term credit facilities or
additional equity financing offerings. There can be no assurance that any such supplemental funding, if sought, could be obtained, or if obtained, would be adequate or on terms acceptable to AIXTRON.
However, AIXTRON believes that its balance sheet at December 31, 2011 should provide additional sources of liquidity if required.

As
of December 31, 2011, € 122.3 million (2010: € 202.6 million; 2009:
€ 90.0 million) of the Company's cash resources were held, mostly in Euros, in bank deposits with a maturity of at least three months.

C.    Research and Development, Patents and Licenses, etc.

For information regarding research and development, patents and licenses, refer to Item 4.B. "Information on the
CompanyBusiness OverviewResearch and Development", "Intellectual Property" and Item 5.A. "Operating and Financial Review and
ProspectsOperating ResultsDevelopment of ResultsOperating Costs" in this report.

D.    Trend Information

The development of state-of-the-art material deposition technology remains AIXTRON's core
competency and one which the Company has developed an acknowledged competitive advantage. AIXTRON Management intends to continue this 'Pure Play' positioning and plans to further expand this core
know-how into both existing and emerging markets. Furthermore, due to an expectation that the speed of development and the competitive environment in the equipment markets that AIXTRON
addresses will become more dynamic, and consequently product life cycles will become shorter, AIXTRON intends to further accelerate and expand its R&D activities. Based on these strategic plans,
AIXTRON expects to maintain its MOCVD equipment market leadership position.

AIXTRON
has a pioneering and leading role in the area of special Silicon Carbide ("SiC") epitaxial equipment utilizing its Hot-Wall Planetary Reactor® technology.
This leading role is planned to be further strengthened within the next years with the adoption of AIXTRON's 6x6 inch multiwafer platform. Customers in Europe, USA, China, Japan and South Korea are
using AIXTRON's SiC equipment for the production of fast-switching diodes with minimized power loss, which are already used in power supplies for computer servers, flat panel TVs and solar
inverters. Furthermore, the Company is active in supplying equipment to the power electronics market for the production of Gallium Nitride ("GaN") on Silicon ("Si") devices, which are expected to
progressively replace Silicon power management devices within the next 2 years. Supported by internal and externally funded development projects, AIXTRON plans to bring its GaN on Si production
technology to market within the next two years.

AIXTRON
will also continue to implement its strategy to address the large area organic semiconductor application markets with the Company's deposition technology for organic materials,
OVPD® and PVPD. Additionally, AIXTRON seeks to make further inroads into the research community with its PECVD technology aimed at manufacturing Carbon Nanostructures
including Carbon Nanotubes, Carbon Nanowires and Graphene.

AIXTRON
has developed a high throughput ALD product aimed at providing innovative solutions for next-generation memory and logic device markets. AIXTRON's product is being
qualified by multiple major chip manufacturers and AIXTRON expects to generate revenues with its technologies as the industry moves to a 28nm technology node and beyond.

For
2011, Gartner Dataquest forecasted (in their report as of December 2011) that the semiconductor capital spending grew by 14% to USD 64.2 billion. In the same report,
Gartner forecasts

33

Table of Contents

a
decline of the semiconductor capital spending of about 20% to USD 51.7 billion (2013e: USD 61.6bn) for 2012. The spending on Wafer Front End equipment, where AIXTRON competes,
is expected to decline by almost 23% year on year in 2012 to USD 26.7 billion (2013e: USD 33.1 billion) according to Gartner Dataquest.

According
to financial and market analysts, the value of MOCVD equipment was expected to have reached a range of approximately USD 1.4 billion to USD 1.8 billion by
the end of 2011 and is expected to develop towards a range of approximately USD 0.6 billion to USD 1.4 billion in 2012 as the market begins to recover from the current
excess of manufacturing capacity for LEDs. In 2013, the same analysts expect the investment activity to pick up again, leading to a market size range of approximately USD 0.8 billion to
USD 1.9 billion.

The
total Silicon power management device market is expected to grow from USD 12 billion to 18 billion between 2010 and 2015 according to Gartner (in December 2011).
The SiC and GaN power electronics devices, which can be produced on AIXTRON equipment, are estimated to generate a USD 500 million device market by 2015. Estimates of an accessible
market size for the respective production equipment is however not meaningful at this point in time.

AIXTRON
Management believes that the markets AIXTRON addresses with its OVPD®, PVPD and PECVD technologies bear substantial growth potential in the
mid- to long-term. However, as with all emerging technologies, there is an element of risk associated with the timing of AIXTRON's technology being adopted by the market.
Estimates of an accessible OLED or Carbon Nanostructure equipment market size or market share are neither available nor meaningful at this point in time.

The
specific market niche to be addressed by AIXTRON's ALD technology for the production of specialized applications such as gate stacks and capacitors is estimated by Gartner Dataquest
(in December 2011) to be valued at USD 378 million by the end of 2011 (2012e: USD 267 million; 2013e: USD 341 million). The exact timing of the market
adoption of AIXTRON's technologies in this space remains difficult to accurately predict at this time.

This
outlook may vary, positively or negatively from our expectations due to the risks and opportunities described elsewhere in the Report. See "Item 3: Key
InformationRisk Factors" and "Forward Looking Statements" at the beginning of the Report.

E.    Off-Balance Sheet Arrangements

The Company has no off-balance sheet arrangements that have or are reasonably like to have a current or future effect on
its financial condition, changes in
financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that is material to investors.

F.     Tabular Disclosure of Contractual Obligations

In the ordinary course of business, AIXTRON's primary contractual obligations regarding cash involve purchase commitments, operating
lease commitments and capital expenditures.

Table of Contents

The
Company outsources a substantial portion of the manufacturing of its operations to third party suppliers. As the Company's products are technologically complex, the lead times for
purchases from its suppliers can vary up to six months. Principally, but not exclusively, contractual commitments are made for specific customer orders or forecast orders. In some circumstances, where
contractual commitments to suppliers for multiple modules or systems reduce the Company's purchase prices per module or system, purchase commitments may be made against anticipated demand. For the
majority of purchase commitments, the Company has flexible delivery schedules depending on the market conditions, which allow the Company, to a certain extent, to delay delivery beyond originally
planned delivery schedule estimates, if necessary.

The
Company leases certain office and plant facilities, office furniture and motor vehicles under various operating leases. Regarding most of the lease commitments for office and plant
facilities, the Company has options to renew the leasing contracts. The leases typically run for a period between one and 15 years. None of the leases includes contingent rentals.

Preparation of Consolidated Financial Statements under IFRS

The Consolidated Financial Statements of AIXTRON SE and its subsidiaries ("AIXTRON" or "Company") have been prepared in accordance
with, and fully comply with



Critical Accounting Policies and Key Sources of Estimation and Uncertainty

The preparation of AIXTRON's Consolidated Financial Statements requires the Company to make certain estimates, judgments and
assumptions that the Company believes are reasonable based upon the information available. These estimates and assumptions affect the reported amounts and related disclosures and are made in order to
fairly present the Company's financial position and results of operations. The following accounting policies are significantly impacted by these estimates and judgments that AIXTRON believes are the
most critical to aid in fully understanding and evaluating its reported financial results include the following:

Revenue Recognition

Revenue is generally recognized in two stages for the supply of equipment to customers, partly on delivery and partly on final
installation and acceptance. The Company estimated the fair value of outstanding installation services based on past experience. The Company believes, based on past experience, that this method of
recognizing revenue fairly states the revenues of the Company. For more information regarding revenue recognition, refer to Item 18 "Financial StatementsNote 2. Significant
accounting policies".

Goodwill

As stated in the accounting policies, the Company tests at least annually whether goodwill has suffered impairment. If there is an
indication, the recoverable amount of the cash generating unit has to be estimated. This is the greater of the fair value less costs to sell and the value in use. The determination of the value in use
involves making adjustments and estimates relate to the projection and discounting of future cash flows. Key assumptions relate to the projected cash flows and discount rates. Although the Company
believes the assumptions used to calculate recoverable amount are appropriate, any unforeseen changes in these assumptions could result in impairment charges to goodwill which could adversely affect
the future financial position and operating results.

Valuation of Inventories

Inventories are stated at the lower of cost and net realizable value. This requires the Company to make judgments concerning
obsolescence of materials. This evaluation requires estimates, including

35

Table of Contents

both
forecasted product demand and pricing environment, both of which may be susceptible to significant change.

In
future periods, write-downs of inventory may be necessary due to (1) reduced demand in the markets in which the Company operates, (2) technological obsolescence due to
rapid developments of new products and technological improvements, or (3) changes in economic or other events and conditions that impact the market price for the Company's products. These
factors could result in adjustment to the valuation of inventory in future periods, and significantly impact the Company's future operating results.

Income Taxes

At each balance sheet date, the Company assesses whether the realization of future tax benefits is sufficiently probable to recognize
deferred tax assets. This assessment requires the exercise of judgment on the part of Management with respect to future taxable income. The recorded amount of total deferred tax assets could be
reduced if estimates of projected future taxable income are lowered, or if changes in current tax regulations are enacted that impose restrictions on the timing or extent of the Company's ability to
utilize future tax benefits.

Recently Issued Accounting Standards

At the date of authorization of these financial statements, the following Standards and amendments to Standards, which have not been
applied in these financial statements, were in issue but not yet effective and not yet adopted by the EU.



The
adoption of IFRS 9 which the Company plans to adopt on 1st January 2015 will impact both the measurement and disclosures of Financial Instruments; other changes to
standards do not have a material impact.

For
more information regarding recently issued accounting standards, refer to Item 18 "Financial StatementsNote 2. Significant accounting policies".

B.    Compensation

Executive Board Remuneration

The remuneration system summarized below pursuant to Section 120(4) of the German Stock Corporation Act was approved by the
General Shareholders' Meeting on May 18, 2010.

The
Supervisory Board is responsible for establishing the structure of the remuneration system and the total remuneration for individual members of the Executive Board. It regularly
discusses and reviews the remuneration for appropriateness.

The
level of remuneration of AIXTRON's Executive Board members is aligned with the commercial and financial situation and future prospects of the Group and the level and structure of
Executive Board remuneration at comparable companies as well as the compensation structure in place in other areas of the Company. In addition, the responsibilities, experience and contribution of
each individual Executive Board member are taken into account when calculating the remuneration.

Executive
Board remuneration currently consists of three components: fixed remuneration (including benefits in kind and payments into a private pension insurance plan), a variable bonus,
and a share-based payment.

The
Executive Board employment contracts stipulate an annual income for the fixed remuneration component. The fixed remuneration component is non-performance-related and is
paid out on a

38

---



Table of Contents

monthly
basis (13 times a year) as a salary. Additional payments in kind are made, chiefly consisting of company car usage and payments for private pension insurance.

The
variable bonus (profit-sharing) is based on consolidated net income for the year and is paid from an "accrued internal bonus", defined as up to 10% of the modified consolidated net
income for the year, but not to exceed € 6.5 million in total. The modified consolidated net income for the year is obtained from the Company's Consolidated
Financial Statements (IFRS) certified by the auditor, less a consolidated loss carry forward figure and those amounts that are to be allocated to retained earnings in the Annual Financial Statements
of AIXTRON by law or in accordance with the Articles of Association. The consolidated loss carry forward is obtained from consolidated net losses from previous years, less consolidated net income from
subsequent fiscal years.

In
addition, as a variable component acting as a long-term incentive with an element of risk, the members of the Executive Board may receive a share-based payment in the form
of options that are granted under AIXTRON's stock option plans. The stock option plans, including the exercise thresholds, are adopted at each General Shareholders' Meeting. The number of options
granted to the Executive Board is stipulated by the Supervisory Board. Further details on the outstanding stock options of the Executive Board as well as comments on the respective stock option plans
are set out further in this report.

The
appropriateness of the above-mentioned remuneration components is regularly reviewed by the Supervisory Board. Attention is also paid to ensuring that the terms of the remuneration
components do not induce the Executive Board to take inappropriate risks.

In
fiscal year 2011, the total fixed and variable remuneration of the Executive Board (including benefits in kind and pension allowance) totaled € 7,623,754
(2010: € 7,620,046; 2009: € 5,148,351). In fiscal year 2011, the Executive Board was not granted any options (2010: 156,000, 2009: 156,000).
The division between the individual members of the Executive Board for the years 2009 to 2011 is presented in the table below.

In accordance with IFRS 2, the "grant-date fair value of the options" is also used as the basis for recognizing options issued
after November 7, 2002 under expenses in the Income Statement. For stock options issued after November 7, 2002, the fair value is calculated using a binomial lattice model, for stock
options issued before November 7, 2002, the fair value was calculated using the Black-Scholes model.

In
fiscal year 2011, the Executive Board members exercised no options (2010: 0; 2009: 0), and none expired (2010: 0; 2009: 0).

The
current Executive Board members have no individual company pension benefits which would result in pension provisions being required to be made by the company. Instead, the combined
Executive Board annual pension allowance (a total of € 120,000 each in 2011, 2010 and 2009) paid by AIXTRON and included in fixed remuneration, is transferred by the
Executive Board members into independent insurance contracts with a benevolent fund allowance (or similar plan).

The
Company's net pension commitments to two former members of the AIXTRON Executive Board under defined benefit pension plans were outsourced to a third party pension fund in 2010. At
the end of 2010, the existing pension provisions were therefore released (2009 € 1,028,464). The non-recurring net expenditure recorded for 2010 amounted to
€ 926,383. There was no expenditure recorded in 2011.

The
Executive Board members receive no loans from the Company.

Supervisory Board Remuneration

The remuneration of the Supervisory Board is regulated by the Articles of Association of AIXTRON SE, as defined and approved by the
General Shareholders' Meeting of May 19, 2011.

Accordingly,
the annual fixed compensation for individual members of the Supervisory Board is € 25,000. The Chairman's compensation is three times this
amount and the Deputy Chairman's one and a half times the amount received by a regular member of the Supervisory Board.

The
members of the Supervisory Board also receive, in aggregate, a variable compensation of 1% of the Company's net income, less an amount corresponding to 4% of the paid-in
contributions to the share capital. The Chairman of the Supervisory Board receives 6/17 of the variable compensation, the Deputy Chairman 3/17, and each other member of the Supervisory
Board 2/17. The variable compensation is limited to four times the fixed compensation per Supervisory Board member. In addition, committee members receive an attendance fee of
€ 2,000 for attending a committee meeting, with the Chairman of the committee receiving three times this amount. The total annual attendance fee per Supervisory Board
member is limited to one and a half times that individual's fixed compensation.

In
a separate resolution approved by the AGM, the remuneration of the first Supervisory Board of AIXTRON SE was approved to reflect the above described provision for the period from
January 1, 2011 to May 19, 2011 inclusive.

In
fiscal year 2011, the compensation of the Supervisory Board totaled 1,024,933 (2010: € 801,000; 2009: € 567,350). The
Supervisory Board compensation for the years 2009 to 2011 can be broken down as follows:

Table of Contents

As in previous years, there were no payments made to any Supervisory Board member for advisory services in the year 2011.

The
Supervisory Board members receive no loans from the Company.

C.    Board Practices

For general information of the Company's board practice, refer to Item 6.A. "Directors, Senior Management and
EmployeesDirectors and Senior Management" in this report. Also refer to Item 10.C. "Additional InformationMaterial Contracts" for further information regarding the
Company's directors' employment contracts.

If
the employment contract of any of the Company's Executive Board Members is terminated without notice for good cause on the part of the Executive Board Member and for which he has to
bear responsibility, the entitlement to the profit sharing bonus lapses from the time that the termination becomes effective, but if it is not for an important reason or if the Executive Board Member
terminates the employment relationship after a change in control, each member of the Executive Board will receive a severance pay in an amount equal to the fixed and variable compensation expected to
be owed by the Company for the remaining term of the service contract, however, not exceeding an
amount equal to twice the annual compensation. A change of control situation exists if a third party or a group of third parties who contractually combine their shares in order to act subsequently as
a third party, directly or indirectly holds more than 50% of the Company's authorized capital. No additional benefits are generally paid to the Company's Executive Board Members upon regular
termination of their employment contracts.

None
of the members of the Supervisory Board has a service contract with the Company or any of its subsidiaries, providing for benefits upon termination of employment.

The
Company has a D&O insurance contract in place, covering the activities of members of the Executive Board and members of the Supervisory Board. Following the entry into force of the
Act on the Appropriateness of Executive Board Compensation (VorstAG), the D&O insurance policies for members of the Executive Board and members of the Supervisory Board of AIXTRON were adjusted to
reflect such new legal requirements. Effective January 1, 2010, the deductible amounts to a minimum of 10% of the respective potential loss incurred, but cannot exceed a factor of 1.5 of the
respective annual fixed remuneration.

Audit Committee

According to Article 16 of AIXTRON's Articles of Association, the Supervisory Board is authorized and, if prescribed by law,
required to form committees of its members.

The
by-laws for the Supervisory Board specify that the Audit Committee is responsible, in particular, for preparing, on behalf of the Supervisory Board, proceedings and
resolutions concerning accounting issues, the accounting process and the effectiveness of the internal control system, the risk management system and the internal audit system, as well as supervising
the audit of the financial statements (and especially the independence of the auditors and any additional services performed by the auditors) and the handling of compliance issues. In addition, the
Audit Committee is responsible for issuing the mandate to audit the annual accounts and the consolidated Group accounts and to carry out any examination of interim reports of AIXTRON SE, for
identifying the main focus areas of the audit and for agreeing on the fee arrangements with the auditors. The Audit Committee forwards to the Supervisory Board its recommendation on which firm should
be appointed as auditor. The Chairman of the Committee regularly reports to the Supervisory Board with regard to the work performed.

AIXTRON's
Audit Committee operates under the terms of reference of a codified Audit Committee charter. The Audit Committee's charter includes the following terms of
reference:

However, the structure of the Executive Board remuneration system is regularly approved by the shareholders at the General Shareholders' Meeting.

May 19, 2011, the Company has established a Technology Committee. The Technology Committee is composed of three members. It deals in particular with issues involving
AIXTRON's market positioning, product planning and developments, potential technology acquisitions or other diversification issues. The Committee Chairwoman regularly reports to the Supervisory Board
on the activities of the Technology Committee. The members of the Technology Committee are Prof. Dr. Petra Denk (Chairwoman), Kim Schindelhauer and Dr. Holger

themselves are granted without purchase price.

In
fiscal year 2011, 609,661 stock options (2010: 513,014 options; 2009: 915,662 options) were exercised, resulting in delivery of in total 609,661 ordinary shares. Under the 2011

be exercised after a waiting period of not less than two years, an additional 25% may be exercised after three years and the remaining 25% of the granted options may be exercised after at least four
years. The options expire 10 years after they have been granted.

Revenues outside of Europe accounted for € 584.6 million or 95.69% of the AIXTRON's total revenues
for the year ended December 31, 2011 (2010: € 752.7 million or 96.04%; 2009: € 261.4 million or 86.30%). Revenues from

Legal Proceedings

In the normal course of business, the Company is subject to various legal proceedings and claims. The Company believes that the matters
the Company is aware of are not likely to have a material adverse effect on its financial condition or results of operations. The Company is not aware of any unasserted claims that may have a material
adverse effect on its financial condition or results of operation.

International
Rectifier Corporation (IRC), of EI Segundo, California, USA had filed a complaint on September 8, 2008 in the U.S. District Court for the Central District of
California against seven of IRC's former employees, including IRC's founder and former CEO Alex Lidow, as well as five companies, including AIXTRON. Having had its lawsuit dismissed in the U.S.
District Court, IRC re-filed essentially the same lawsuit in California state court in March 2009 based on the California state claims alone, and alleged five causes of action against
AIXTRON. After multiple rounds of motions to dismiss, IRC dropped some of its claims against the defendants, and the California court dismissed additional claims. As at December 31, 2010, two
of IRC's claims remained in the case against AIXTRON.

On
January 24, 2011, AIXTRON and IRC entered into a settlement agreement in which IRC agreed to withdraw its action in return for voluntary disclosure by AIXTRON of certain
documents as well as witness statements to IRC in support of IRC's still pending action against the remaining defendants. In
February 3, 2011, the Superior Court of California, County of Los Angeles, California, USA has filed and entered the dismissal with prejudice of the action against AIXTRON.

Policy on Dividend Distributions

The maximum amount of dividends available for distribution to shareholders is based on the level of earnings, as determined in

SE, the parent company of the AIXTRON Group, recorded a net accumulated income in accordance with German generally accepted accounting principles (German GAAP), based on the

€ 42.5 million).

AIXTRON's
Executive and Supervisory Boards will propose to the shareholders' meeting that a dividend of € 25.4 million or

Item 10:    Additional Information

A.    Share Capital

Not applicable.

B.    Memorandum and Articles of Association

Articles of Association

This section summarizes the material provisions of AIXTRON's Articles of Association. This is only a summary and does not describe the
Articles of Association in their entirety. Copies of AIXTRON's Articles of Association are publicly available from the commercial register of the local court in Aachen, Germany under the entry number
HRB 16590, and an English translation of AIXTRON's Articles of Association as of January 25, 2012 is also available on the AIXTRON website and can be found in Exhibit 1.1 of this
report.

Share Capital

The Company's share capital amounts to € 101,789,527 as per January 31, 2012. It is composed of
101,789,527 no-par value registered shares.

Purpose

According to Section 2 of AIXTRON's Articles of Association, the purpose of the Company is the manufacture and sale of products,
as well as research and development and services for the implementation of semiconductor technologies and other physicochemical technologies, particularly those bearing the AIXTRON trademark. The
Company is authorized to conduct all transactions suitable for promoting the Company's purpose indirectly and directly. The Company may establish branch offices in Germany and abroad, may acquire
equity interests in other companies in Germany and abroad, as well as purchase or establish such companies. The purpose of subsidiaries and investees may differ from that referred to above insofar as
it seems capable of promoting the purpose of the Company. The Company may outsource all or part of its operations to affiliates.

Future Share Capital; Preemptive Rights

AIXTRON's stated share capital may be increased against either contributions of cash or contributions-in-kind
by a resolution of AIXTRON's General Shareholders' Meeting with a 75% majority of the share capital represented at the meeting at which the resolution is adopted, or under AIXTRON's Articles of
Association by a resolution of the Executive Board with the consent of the Supervisory Board by using AIXTRON's authorized share capital.

In
accordance with the German Stock Corporation Law, an existing shareholder in a stock corporation has a preemptive right to subscribe for any issue of new shares, debt instruments
convertible into shares (Wandelschuldverschreibungen) and participating debt instruments (Genussrechte) in proportion to the number of shares held by that shareholder in the existing stated share
capital of the company. The General Shareholders' Meeting may exclude this preemptive right by a majority of at least 75% of the share capital represented at the meeting at which the resolution
authorizing the capital increase is adopted. In addition to these formal procedural requirements, the exclusion requires a substantive justification. The Executive Board is required to submit a
written report concerning this justification to the General Shareholders' Meeting. The goal pursued by the corporation through the issuance of the new security must outweigh the elimination of this
preemptive right and that the goal could not be reasonably achieved without it.

The
preemptive rights are freely assignable and may be traded on German stock exchanges for a specified time within the subscription period. The preemptive rights lapse if they are not
exercised.

Dividend and Liquidation Rights

The ordinary shares underlying the AIXTRON ADSs are fully entitled to any dividends as and when declared by AIXTRON. Upon proposal by
AIXTRON's Executive Board and Supervisory Board, the annual General Shareholders' Meeting approves the allocation of AIXTRON's net profits (Bilanzgewinn), which AIXTRON determines on the basis of its
unconsolidated annual financial statements prepared in accordance with the accounting principles generally accepted in Germany. The

49

---



Table of Contents

Executive
Board and the Supervisory Board are authorized to allocate, in their discretion, up to half of AIXTRON's net profit in any fiscal year to other retained earnings
(andere Gewinnrücklagen). Shareholders participate in dividends in proportion to the number of shares held by each shareholder.

In
accordance with the German Stock Corporation Law, upon AIXTRON's liquidation, shareholders will receive, in proportion to their shareholdings, any liquidation proceeds remaining after
payment of all of AIXTRON's liabilities.

Voting Rights and General Shareholders' Meeting

A General Shareholders' Meeting of AIXTRON may be called by the Executive Board, the Supervisory Board or upon request of shareholders
whose aggregate holding is not less than 5% of the stated share capital. The annual General Shareholders' Meeting must take place within the first six months of the fiscal year. The Executive Board
calls this meeting upon the receipt of the Supervisory Board's report on the annual financial statements.

Under
German law and AIXTRON's Articles of Association, AIXTRON must publish notices of shareholders meetings in the German electronic federal gazette
(elektronischer Bundesanzeiger) at least one month before the last day on which the shareholders must deposit their shares for the meeting.

Under
AIXTRON's Articles of Association, those shareholders whose names are entered into the share register on the date of the General Shareholders' Meeting and who have registered for
participation in a timely manner shall be entitled to participate in such General Shareholders' Meeting and to exercise their voting rights. Such registration for participation must be received at the
Company under the address notified for this purpose in the call for the meeting in German or English in the form of text or, if so resolved by the Executive Board, electronically in a manner
determined in the call for the General Shareholders' Meeting, at least six days prior to the General Shareholders' Meeting, whereby the date of the General Shareholders' Meeting and the date of
receipt are not taken into account. Cancellations and new registration in the share register will not take place on the date of the General Shareholders' Meeting and during the last six days prior to
the General Shareholders' Meeting.

The
Executive Board is authorized to provide that shareholders can participate in the General Shareholders' Meeting without being present at its location and without a proxy and can
completely or partially exercise all or individual rights they have by means of electronic communication.

Each
ordinary share carries one vote at General Shareholders' Meeting. According to AIXTRON's Articles of Association, resolutions are generally passed with a simple majority of the
votes cast unless otherwise required by the Articles of Association or by law. Resolutions that require a majority of the share capital represented at the time of the adoption of the resolution are
passed with a simple majority of the share capital represented at the meeting of shareholders at which the resolution is considered, unless otherwise required by law. Resolutions about amending the
Articles of Association, to the extent legal provisions do not determine otherwise, require a majority of two thirds of the votes cast or, if at least one half of the share capital is represented, a
simple majority of the votes cast. Under the German Stock Corporation Law, a number of significant resolutions must be passed by a majority of the votes cast and at least 75% of the share capital
represented in connection with the vote taken on that resolution. The approval threshold required for some of these resolutions may be lowered by the Articles of Association.

The
following resolutions require the approval of a majority of at least 75% of the share capital represented at the meeting:

Although
AIXTRON must notify shareholders of any ordinary or extraordinary shareholders' meeting as described above, neither the German Stock Corporation Law nor AIXTRON's Articles of
Association fixes a minimum quorum requirement. This means that holders of a minority of AIXTRON's shares could control the outcome of resolutions not requiring a specified majority of AIXTRON's
stated share capital.

Notice Requirements

In accordance with the German Stock Corporation Law, each enterprise owning AIXTRON ordinary shares must notify AIXTRON promptly if the
aggregate number of ordinary shares it holds exceeds or falls below 25% of AIXTRON's share capital or if it acquires or disposes of the majority of AIXTRON's voting rights. For any period in which a
notice is not given, the enterprise is prevented from exercising its rights as an AIXTRON shareholder, including voting rights and dividend rights.

The
German Securities Trading Act (Wertpapierhandelsgesetz) provides for extensive notification requirements. It requires each person
whose voting rights reach, exceed or, after exceeding, fall below the 3%, 5%, 10%, 15%, 20%, 25%, 30%, 50% or 75% voting rights thresholds in a company to notify the company and the Federal
Supervisory Agency (Bundesanstalt für Finanzdienstleistungsaufsicht) in writing within four trading days after they have reached,
exceeded or fallen below that threshold. For any period in which a notice is not given, the shareholder is prevented from exercising its rights as an AIXTRON shareholder, including voting rights and
dividend rights. In addition, anyone who holds, directly or indirectly, financial or other instruments that (i) grant an entitlement to acquire voting shares issued by a company whose home
member state is the Federal Republic of Germany or (ii) which do not grant an enforceable right to acquire such shares, but still make such acquisition (economically) possible must, without
undue delay, notify the issuer and the Federal Supervisory Agency if the thresholds mentioned above, with the exception of the 3% threshold, have been reached, exceeded or fallen below. In making the
threshold calculations, positions in voting rights must be aggregated with positions in such financial instruments..

Notices, Paying Agent and Depository

AIXTRON publishes official notices exclusively in the German electronic federal gazette (elektronischer
Bundesanzeiger).

In
addition, AIXTRON will file reports and other information with the SEC.

Deutsche
Bank AG is the German Paying Agent (Zahlstelle) for the AIXTRON ordinary shares.

There
are no limitations on rights to own AIXTRON ordinary shares.

Corporate Governance

AIXTRON's Declaration of Conformity with the recommendations of the Government Commission of the German Corporate Governance Code was
last updated in February 2012 and states that the Company has been in full compliance with the Corporate Governance Code. It is posted together with the "Declaration on Corporate Governance" in the
"Investor RelationsCorporate Governance" section of AIXTRON's website at www.aixtron.com.

AIXTRON
has had a Code of Ethics procedure since 2006 for the Executive Board members and selected key managers in Finance. For more details to the Company's Code of Ethics refer to
Item 16B: Code of Ethics.

In
addition, AIXTRON has issued a Code of Conduct applicable to all employees in all Company offices throughout the world and holds them accountable to conduct that is ethical and in
conformity with the law. The Code covers, amongst other topics, the following issues: Responsibility and respect towards mankind and the environment, compliance with overall legal conditions, legal
and ethical conduct by each individual employee, loyalty to the Company, fair and respectful treatment of fellow employees, rejection of any form of discrimination, dealing responsibly with corporate
risks, acting in an environmentally aware manner, security in all operating areas, professional work, reliability and

in all business relationships, compliance with guidelines on giving/taking unfair advantage, dealing with insider information and treatment of Company property. A copy of the Code of Conduct
is available on the AIXTRON website www.aixtron.com under the section Investors / Corporate Governance / Code of Conduct.

In
2011, AIXTRON has issued a Compliance Manual which applies to all members of the senior management. This manual is based on the principles of the Compliance Code of Conduct and
provides a detailed view on all important areas of compliance. It is regularly being updated to reflect legal changes. By signing a representation letter, the senior managers confirm having informed
their team members about the content of the Compliance Manual and that the compliance rules and regulations set out by AIXTRON SE are being complied with.

The
information available on AIXTRON's website is not incorporated by reference into this report.

Sarbanes-Oxley Act Requirements and NASDAQ Rules

To facilitate the Company's compliance with the Sarbanes-Oxley Act, the U.S. Securities Exchange Act of 1934, as amended (the "Exchange
Act") and the rules of the NASDAQ Stock Market (the "NASDAQ Rules"), AIXTRON has established a Disclosure Committee that is responsible for reviewing and approving its public disclosures. AIXTRON also
has procedures for handling complaints related to accounting practices and a Code of Ethics.

In
conjunction with its annual report for the year ending December 31, 2011, the Company is required to include a report from its Management relating to its evaluation of the
Company's internal control over financial reporting, as required pursuant to Section 404 of the U.S. Sarbanes-Oxley Act, see Item 15 in this annual report on
Form 20-F.

AIXTRON
generally complies with applicable German Corporate Governance practice rather than certain of the Corporate Governance requirements of NASDAQ. The requirements of NASDAQ that
AIXTRON is not following and its non-conforming practices in lieu thereof are as follows:



52

---



Table of Contents



Other
significant differences between AIXTRON's governance practices and those of U.S. domestic NASDAQ-listed companies are as follows:

Two-Tier Board

In accordance with the requirements of the German Stock Corporation Act, to which AIXTRON SE is subject via the SE statutes, AIXTRON
has a two-tier board structure consisting of an Executive Board and a Supervisory Board, which is not comparable to the one-tier or unitary board system in the U.S. The
two-tier governance system provides a strict separation of management and supervisory functions. Roles and responsibilities of each of the two boards are clearly defined by law.

Independence

Under this two-tier board system, except as described above, AIXTRON's methods for determining and ensuring the
independence of its Supervisory Board differ from those of NASDAQ Rule 5605, which generally contemplates a U.S.-style, one-tier system. In contrast to the NASDAQ Rules, which
require the board to affirmatively determine the independence of the individual directors with reference to specific tests of independence, German law does not require the Supervisory Board to make
such affirmative findings on an individual basis. At the same time, the Bylaws of AIXTRON's Supervisory Board contain several provisions to help ensure the independence of the Supervisory Board's
advice and supervision. Furthermore, the members of AIXTRON's Supervisory and Executive Boards are strictly independent from one another. A member of one board is legally prohibited from being
concurrently active on the other. Supervisory Board members have independent decision making authority and are legally prohibited from following the direction or instruction of any affiliated party.
Moreover, Supervisory Board members may not enter into advisory, service or certain other contracts with AIXTRON, unless approved by the Supervisory Board.

Compliance with the requirements of NASDAQ Rule 5600 Series applicable to foreign private issuers

Under Rule 5615(a)(3), as amended, AIXTRON is required to comply with Rule 5625 (relating to the notification of material
noncompliance), Rule 5640 (relating to certain voting rights and to have an Audit Committee that satisfies Rule 5605(c)(3) (regarding compliance with Rule 10A-3 of the
Exchange Act) and to ensure that such Audit Committee's members meet the independence requirement in 5605(c)(2)(A)(ii) (regarding independence required under Rule 10A-3 of the
Exchange Act).

AIXTRON's
Supervisory Board has determined that as of December 31, 2011, the Company is in compliance with the aforementioned requirements applicable to foreign private issuers
pursuant to Rule 5600 Series. In particular, AIXTRON's Supervisory Board has determined that each member of the Audit Committee is "independent" as set forth in Rule 10A-3 of
the Exchange Act and as required by Rule 5605(c)(2)(A)(ii).

C.    Material Contracts

Apart from the following material contracts, all contracts AIXTRON has entered into during the course of the year 2011 were entered in

Table of Contents

Polytechnique
de Grenoble ("INPG") executed on December 17, 2002 (the "CNRS Agreement") is confidential and has been redacted from the copies of the CNRS Agreement AIXTRON filed with the SEC.

The
CNRS Agreement deals with the system for injection of precursors into a vacuum vapor deposition chamber (the "Product"). CNRS and INPG grant AIXTRON an exclusive license to develop,
manufacture, use, sell the Product and exploit the patents and know-how in the entire world with the right to grant certain sub-licenses. Except for the specified
sub-license grants, the CNRS Agreement is personal, not assignable and non-transferable. The CNRS Agreement remains in force during the life of the patents unless it is
terminated by any of the parties to this agreement.

D.    Exchange Controls

At present, Germany does not restrict the movement of capital between Germany and other countries or individuals except certain
persons, entities and countries subject to embargoes in accordance with German law and applicable resolutions adopted by the United Nations and the European Union.

For
statistical purposes, with certain exceptions, every corporation or individual residing in Germany must report to the German Central Bank any payment received from or made to a
non-resident corporation or individual if the payment exceeds € 12,500 (or the equivalent in a foreign currency). Additionally, corporations and individuals
residing in Germany must report to the German Central Bank any claims of a resident against, or liabilities payable to, a non-resident corporation or individual exceeding an aggregate of
€ 5 million (or the equivalent in a foreign currency) at the end of any calendar month.
Resident corporations and individuals are also required to report annually to the German Central Bank any stakes of 10% or more they hold in the equity of non-resident corporations with
total assets of more than € 3 million. Corporations residing in Germany with assets in excess of € 3 million must report
annually to the German Central Bank any stake of 10% or more in the company held by an individual or a corporation located outside Germany.

E.    Taxation

German Taxation

The following discussion is a summary of certain material German tax consequences for beneficial owners of AIXTRON's ordinary shares or
ADSs:



The
discussion is based on tax laws of Germany as in effect on the date of this annual report, including the Convention between the United States of America and the Federal Republic of
Germany for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion With Respect to Taxes on Income and Capital and to Certain Other Taxes (the "Treaty"). Such laws are subject to
change. The discussion is also based in part upon the representations of the Depositary and assumes that each obligation in the Deposit Agreement and any related agreement will be performed in
accordance with its terms.

The
following discussion does not purport to be a comprehensive discussion of all German tax consequences that may be relevant for Non-German Holders. AIXTRON's discussion
does not address all aspects of German taxation that may be relevant to you in light of your particular circumstances. You should consult your tax advisor regarding the German federal, state and local
tax consequences of the purchase, ownership and disposition of AIXTRON's shares or ADSs and the procedures to follow to obtain a refund of German taxes withheld from dividends.

Taxation of the Company in Germany

German Corporations are subject to a corporate tax rate of 15%. A 5.5% solidarity surcharge is imposed on the Corporation Tax,
resulting in an overall tax rate of 15.825%.

55

---





Table of Contents

In addition, German corporations are by virtue of their legal form subject to a municipal profit-related German Trade Tax. Trade Tax is calculated on the basis of
the taxable Corporation Tax income as shown in the annual statutory profit and loss accounts of the corporation which, however, is subject to certain particular Trade Tax add-backs and
deductions. The effective Trade Tax rate applicable depends on the municipality in which the corporation maintains a permanent establishment and ranges between approximately 7% and 17%.

German
Corporation Tax and Trade Tax combined will result in an overall tax burden for German corporations amounting to approximately 30% at an average.

The
deduction for a taxable loss carry-forward for the fiscal year is unlimited up to a threshold of € 1,000,000, thereafter taxable income can only be
offset to the extent of 60%. The temporary loss carry-forward is reduced by the amount used and remains unlimited in life. However, there are limitations on the use of loss carry-forwards upon a
transfer of more than 25% of a corporation's shares or voting rights to one purchaser, a related party or group of purchasers within a specified time period.

Withholding Tax on Dividends

Withholding Tax on Dividends in Germany constitutes 25%. A solidarity surcharge of 5.5% on the withholding tax results in a surcharge
amount to 1.375% (5.5% × 25%), and a total effective withholding tax rate from dividends of 26.375%. For many Non-German Holders, the withholding tax rate is reduced under
applicable income tax treaties. Under most income tax treaties to which Germany is a party, the rate of dividend withholding tax is reduced to 15%. To reduce the withholding to the applicable treaty
rate of 15%, a Non-German Holder must apply for a refund of withholding taxes paid. The application for refund must be filed with the German Federal Tax Office. The relevant forms can be
obtained from the German Federal Tax Office or from German embassies and consulates.

Special Tax Rules for tax resident in Germany

From January 1, 2009 onwards 100% of dividends of shares held as private assets will be subject to a 25% fixed tax rate plus
5.5% solidarity surcharge thereon. If church tax is individually applicable for the shareholder this part of taxation will be subject of the withholding as well. This tax will be final unless the
individual tax rate of the shareholder is less than 25% and the shareholder opts for the tax assessment. Moreover, from 2009 on, capital gains from the sales of shares, acquired after
December 31, 2008, will be taxable as well, regardless of the percentage of the shareholding and of how long the shareholding has been held. Capital gains from the sale of shares acquired
before January 1, 2009 are tax exempt if the shareholding has been held for more than one year and the taxpayer has held less than 1% of the registered share capital of the company during a
five-year period immediately preceding the disposition. The lump sum deduction of investment income related expenses amounts to € 801 for individuals and
€ 1,602 for married couples. Further investment income related expenses will not be tax deductible.

Regarding
shares held as business assets of the shareholder, 60% of the dividends will be subject to personal income tax (part income taxation). Accordingly, 60% of the income related
expenses are deductible.

Special Tax Rules for U.S. Shareholders

Under the current Treaty, the withholding tax rate generally is reduced to 15% of the gross amount of the dividends and a full refund
of the solidarity surcharge can be obtained by U.S. holder. Dividend payments to an eligible U.S. holder made by AIXTRON will be subject to a 15% general withholding tax rate under the Treaty.

Dividend
distributions made by the Company are subject to a 25% withholding tax plus a solidarity surcharge of 5.5% on the withholding tax resulting in an aggregate German withholding
tax of 26.375% of the declared dividend, and eligible U.S. holders (as defined below under "U.S. Taxation") are entitled to receive a payment from the German tax authorities equal to 11.375% of the
declared dividend.

Accordingly,
for a declared dividend of 100, an eligible U.S. holder initially will receive 73.625: 100 minus the 26.375% withholding tax. The eligible U.S. holder is then entitled to a
refund from the German tax authorities of 11.375 and will, as a result, effectively receive a total of 85 (i.e., 85% of the declared dividend).

Withholding Refund Procedure for U.S. Shareholders

For shares and ADSs kept in custody with The Depository Trust Company in New York or one of its participating banks, the German tax
authorities have introduced a collective procedure for the refund of German dividend, capital withholding tax and the solidarity surcharge thereon on a trial basis. Under this procedure, The
Depository Trust Company may submit claims for refunds payable to eligible U.S. holders under the Treaty collectively to the German tax authorities on behalf of these eligible U.S. holders.

The
German Federal Tax Office will pay the refund amounts on a preliminary basis to The Depository Trust Company, which will redistribute these amounts to the eligible U.S. holders
according to the regulations governing the procedure. The German Federal Tax Office may review whether the refund was made in accordance with the law within four years after making the payment to The
Depository Trust Company. Details of this collective procedure are available from The Depository Trust Company. Individual claims for refunds may be made on a special German form which must be filed
with the German Federal Tax Office (Bundeszentralamt für Steuern, Dienstsitz Bonn, An der Küppe 1, 53225 Bonn, Germany). Copies of this form can be downloaded from
the homepage of the German Federal Tax Office:

http://www.bzst.bund.deorhttp://www.germantaxes.info

or
can be obtained from the Embassy of the Federal Republic of Germany, 4645 Reservoir Road, N.W., Washington, D.C. 20007-1998. Claims must be filed within a four-year period
from the end of the calendar year in which the dividend was received.

As
part of the individual refund claim, an eligible U.S. holder must submit to the German tax authorities the original bank voucher (or a certified copy thereof) issued by the paying
agent documenting the tax withheld, and an official certification on IRS Form 6166 of its last United States federal income tax return. Form 6166 is a letter printed on U.S. Department
of Treasury stationery certifying that the individuals or entities listed are residents of the United States for purposes of the income tax laws of the United States. The Internal Revenue Service
(IRS) procedure for requesting a certificate of residency (Form 6166) from the Philadelphia Accounts Management Center is the submission of Form 8802, Application for United States
Residency Certification. This form may be obtained by filing a request with the Internal Revenue Service Center in Philadelphia, Pennsylvania, P.O. Box 71052, Philadelphia, PA
19176-6052 U.S.A. Requests for certification must include the eligible U.S. holder's name, Social Security or Employer Identification Number, tax return form number, and tax period for
which the certification is requested. Requests for certifications can include a request to the Internal Revenue Service to send the certification directly to the German tax authorities. If no such
request is made, the Internal Revenue Service will send a certification on IRS Form 6166 to the eligible U.S. holder, who then must submit this document with his refund claim.

Taxation of Capital Gains for U.S. Shareholders

Capital Gains earned by a Non-German holder from the sale or other disposition of ordinary shares or ADS are subject to tax
in Germany at statutory tax rates if the Non-German holder has held, directly or indirectly, shares or ADSs representing 1% or more of the registered share capital of the company at any
time during a five-year period immediately preceding the disposition. Capital gains in general are not taxable if the above mentioned threshold is not exceeded and certain further
conditions are met.

The
Income Tax Treaty provides that taxation in Germany on capital gains of U.S. residents does not apply to gains on the sale or other disposition of ADSs or Ordinary shares.

Inheritance and Gift Tax

The current Estate Tax Treaty provides that an individual whose domicile is determined to be in the United States for purposes of such
Treaty will not be subject to German inheritance and gift tax (the equivalent of the United States federal estate and gift tax) on the individual's death or making of a gift unless the ADSs or
Ordinary Shares (1) are part of the business property of a permanent establishment located in Germany or (2) are part of the assets of a fixed base of an individual located in Germany
and used for the performance of independent personal services. An individual's domicile in the United States, however does not prevent imposition of German inheritance and gift tax with respect to an
heir, donee, or other beneficiary who either is or is deemed to be resident in Germany at the time the individual died or the gift was made.

57

---



Table of Contents

The
Estate Tax Treaty also provides a credit against U.S. federal estate and gift tax liability for the amount of inheritance and gift tax paid to Germany, subject to certain
limitations, in a case where the ADSs or Ordinary Shares are subject to German inheritance or gift tax and U.S. federal estate or gift tax.

Other Taxes

No German transfer, stamp or similar taxes apply to the purchase, sale or other disposition of shares or ADSs by Non-German
Holder. Currently, net worth tax is not levied in Germany.

U.S. Federal Taxation

The following is a summary of the principal U.S. federal income tax consequences that may be relevant with respect to the acquisition,
ownership and disposition of AIXTRON's shares or ADSs. This summary addresses only the U.S. federal income tax considerations of holders that hold shares or ADSs as capital assets. This summary does
not address tax considerations applicable to holders that may be subject to special tax rules, such as:



Moreover,
this summary does not address the U.S. federal estate and gift or alternative minimum tax consequences of the acquisition, ownership and disposition of AIXTRON's shares or
ADSs. This summary is based on (1) the federal tax laws of the United States as in effect and available on the date of this annual report, including the Internal Revenue Code of 1986, as
amended (the "Code"), judicial and administrative interpretations thereof, and currently effective and proposed U.S. Treasury Regulations, each as available on the date hereof, and (2) in part
on the representations and covenants of the Depositary and the assumption that each obligation in the Deposit Agreement and any related agreement will be performed in accordance with its terms. All of
the foregoing is subject to change, which change could apply retroactively and could affect the tax consequences described below.

For
purposes of this summary, a "U.S. Holder" is a beneficial owner of AIXTRON's shares or ADSs that, for U.S. federal income tax purposes, is: (1) a citizen or resident of the
U.S., (2) a partnership or corporation created or organized in or under the laws of the United States or any state thereof or the District of Columbia, (3) an estate, the income of which
is subject to U.S. federal income taxation regardless of its source or (4) a trust if such trust validly elects to be treated as a U.S. person for U.S. federal income tax purposes or if
(a) a court within the U.S. is able to exercise primary supervision over its administration and (b) one or more U.S. persons have the authority to control all of the substantial
decisions of the trust. A "Non-U.S. Holder" is a beneficial owner of AIXTRON's shares or ADSs that is not a U.S. Holder.

If
a partnership (or any other entity treated as a partnership for U.S. federal income tax purposes) holds AIXTRON's shares or ADSs, the tax treatment of such partnership and a partner
in such partnership generally will depend on the status of the partner and the activities of the partnership. Such a partnership or partner should consult its own tax advisor as to its consequences.

Each
prospective purchaser should consult his/her own tax advisor with respect to the U.S. federal, state, local and foreign tax consequences of acquiring, owning or disposing of
AIXTRON's shares or ADSs.

Ownership of ADSs in general

For U.S. federal income tax purposes, a holder of ADSs generally will be treated as the owner of the shares represented by such ADSs.
The U.S. Treasury Department has expressed concern that depositaries for ADSs, or other intermediaries between the holders of shares of an issuer and the issuer, may be taking actions that are
inconsistent with the claiming of U.S. foreign tax credits by U.S. Holders of such receipts or shares. Accordingly, the analysis regarding the availability of a U.S. foreign tax credit for German
taxes and sourcing rules described below could be affected by future actions that may be taken by the U.S. Treasury Department.

Distributions

Subject to the discussion below under "Passive Foreign Investment Company Considerations," the gross amount of any
distribution the Company makes of cash or property (other than certain distributions, if any, of shares distributed pro rata to all AIXTRON shareholders, including holders of ADSs) with respect to
shares or ADSs, before reduction for any German taxes withheld there from, will be includible in income by a U.S. Holder as dividend
income to the extent such distributions are paid out of the Company's current or accumulated earnings and profits as determined under U.S. federal income tax principles. Subject to the discussion
below under "Passive Foreign Investment Company Considerations," individuals who are U.S. Holders may be taxed on any such dividends received in a taxable year beginning on or before
December 31, 2012 at the lower tax rate applicable to long-term capital gains (i.e., gains from the sale of capital assets held for more than one year). In order to qualify
for the preferential rate of taxation, certain requirements must be met, including certain holding period requirements and the absence of certain risk reduction transactions with respect to the shares
or ADSs. Such dividends will not be eligible for the dividends received deduction generally allowed to corporate U.S. Holders. Subject to the discussion below under "Passive Foreign
Investment Company Considerations," to the extent, if any, that the amount of any distribution AIXTRON makes exceeds its current and accumulated earnings and profits as determined under U.S. federal
income tax principles, it will be treated first as a tax-free return of the U.S. Holder's adjusted tax basis in the shares or ADSs and thereafter as capital gain. AIXTRON does not maintain
calculations of its earnings and profits under U.S. federal income tax principles.

Any
such dividend paid in Euros will be included in the gross income of a U.S. Holder in an amount equal to the US-Dollar value of the Euros on the date of receipt, which in
the case of ADSs, is the date they are received by the depositary. The amount of any distribution of property other than cash will be the fair market value of such property on the date of
distribution. A U.S. Holder may elect to deduct in computing his/her taxable income or, subject to certain complex limitations on foreign tax credits generally, credit against its U.S. federal income
tax liability German withholding tax at the rate applicable to such U.S. Holder. As discussed under "German TaxationSpecial Tax Rules for U.S. Shareholders" above in this Item 10
under the Treaty, dividends paid by AIXTRON to a U.S. Holder generally will be subject to a German withholding tax rate of 15%. Such reduced rate of withholding will apply only if such U.S. Holder is
treated as a resident of the U.S. for purposes of such Treaty and otherwise is entitled to the benefits of such treaty and the dividends are not effectively connected with a permanent establishment or
fixed base of such U.S. Holder that is situated in Germany.

Dividends
received by a U.S. Holder with respect to ordinary shares or ADSs will be treated as foreign source income, which may be relevant in calculating such holder's foreign tax
credit limitation. The limitation on foreign taxes eligible for credit is calculated separately with respect to specific classes of income. For purposes of calculating the U.S. foreign tax credit,
dividends paid by AIXTRON generally will constitute "passive category income," or in the case of certain U.S. Holders, "general category income." U.S. Holders should consult their tax advisors
regarding the availability of, and limitations on, any such foreign tax credit.

Subject
to the discussion under "Backup Withholding Tax and Information Reporting Requirements" below in this section, a Non-U.S. Holder of shares or ADSs generally will not
be subject to U.S. federal income or withholding tax on dividends received on shares or ADSs, unless such income is effectively connected with the conduct by such Non-U.S. Holder of a
trade or business in the United States.

Table of Contents

Sale or exchange of shares or ADSs

Subject to the discussion below under "Passive Foreign Investment Company Considerations," a U.S. Holder generally will
recognize gain or loss on the sale or exchange of shares or ADSs equal to the difference between the amount realized on such sale or exchange and the U.S. Holder's adjusted tax basis in the shares or
ADSs. Such gain or loss will be capital gain or loss. In the case of a non-corporate U.S. Holder, the maximum marginal U.S. federal income tax rate applicable to such gain will be lower
than the maximum marginal U.S. federal income tax rate applicable to ordinary income (other than certain dividends) if such U.S. Holder's holding period for such shares or ADSs exceeds one year. Gain
or loss, if any, recognized by a U.S. Holder generally will be treated as U.S. source income or loss for U.S. foreign tax credit purposes. The deductibility of capital losses is subject to
limitations.

A
U.S. Holder's initial tax basis in shares or ADSs will be the US-Dollar value of the Euro denominated purchase price determined on the date of purchase. If the shares or
ADSs are treated as traded on an "established securities market," a cash basis U.S. Holder, or, if it elects, an accrual basis U.S. Holder, will determine the dollar value of the cost of such shares
or ADSs by translating the amount paid at the spot rate of exchange on the settlement date of the purchase. If a U.S. Holder converts US-Dollars to Euros and immediately uses that currency
to purchase shares or ADSs, such conversion generally will not result in taxable gain or loss to such U.S. Holder. With respect to the sale or exchange of shares or ADSs, the amount realized generally
will be the US-Dollar value of the payment received determined on (1) the date of receipt of payment in the case of a cash basis U.S. Holder and (2) the date of disposition
in the case of an accrual basis U.S. Holder. If the shares or ADSs are treated as traded on an "established securities market," a cash basis taxpayer, or, if he/she elects, an accrual basis taxpayer,
will determine the US-Dollar value of the amount realized by translating the amount received at the spot rate of exchange on the settlement date of the sale.

Subject
to the discussion under "Backup Withholding Tax and Information Reporting Requirements" below in this section, a Non-U.S. Holder of shares or ADSs generally will not
be subject to U.S. federal income or withholding tax on any gain realized on the sale or exchange of such shares or ADSs unless (1) such gain is effectively connected with the conduct by such
Non-U.S. Holder of a trade or business in the U.S. or (2) in the case of any gain realized by an individual Non-U.S. Holder, such holder is present in the U.S. for
183 days or more in the taxable year of such sale or exchange and certain other conditions are met.

Passive Foreign Investment Company Considerations

A Non-U.S. corporation will be classified as a "passive foreign investment company," or a PFIC, for U.S. federal income tax
purposes in any taxable year in which, after applying certain look-through rules, either: (i) at least 75% of its gross income is "passive income;" or (ii) at least 50% of
the average value of its gross assets is attributable to assets that produce passive income or are held for the production of passive income. Passive income for this purpose generally includes
dividends, interest, royalties, rents and gains from commodities and securities transactions.

Based
on certain estimates of the Company's gross income and gross assets and the nature of the Company's business, AIXTRON does not believe it was a PFIC for the taxable year ending
December 31, 2011. AIXTRON's status in future years will depend on its assets and activities in those years. AIXTRON has no reason to believe that its assets or activities will change in a
manner that would cause the Company to be classified as a PFIC, but there can be no assurance that AIXTRON will not be considered a PFIC for any taxable year. If AIXTRON were a PFIC, U.S. Holders
generally would have additional U.S. tax filing requirements and would be subject to imputed interest charges and other disadvantageous tax treatment with respect to any gain from the sale or exchange
of, and certain distributions with respect to, shares or ADSs.

If
AIXTRON were a PFIC, U.S. Holders could make a variety of elections that may alleviate certain tax consequences referred to above, and one of these elections may be made
retroactively. However, it is expected that the conditions necessary for making certain of such elections will not apply in the case of AIXTRON's shares and the ADSs. U.S. Holders should consult their
own tax advisor regarding the tax consequences that would arise if AIXTRON were to be treated as a PFIC.

Backup withholding tax and information reporting requirements

U.S. backup withholding tax and information reporting requirements generally apply to certain payments to certain holders of stock.
Information reporting generally will apply to payments of dividends on, and to proceeds from the sale or redemption of, shares or ADSs made within the United States, or by a U.S. payor or U.S.
middleman to a holder of shares or ADSs, other than an "exempt recipient." A payor will be required to withhold backup withholding tax from any payments of dividends on, or the proceeds from the, sale
or redemption of, shares or ADSs within the United States to a holder, or by a U.S. payor or U.S. middleman, other than an "exempt recipient," if such holder fails to furnish its correct taxpayer
identification number or otherwise fails to comply with, or establish an exemption from, such backup withholding tax requirements. The backup withholding rate is 28% for taxable years through 2012.

In
the case of such payments made within the U.S. to a foreign simple trust, a foreign grantor trust or a foreign partnership, other than payments to a foreign simple trust, a foreign
grantor trust or a foreign partnership that qualifies as a "withholding foreign trust" or a "withholding foreign partnership" within the meaning of the applicable U.S. Treasury Regulations and
payments to a foreign simple trust, a foreign grantor trust or a foreign partnership that are effectively connected with the conduct of a trade or business in the U.S., the beneficiaries of the
foreign simple trust, the persons treated as the owners of the foreign grantor trust or the partners of the foreign partnership, as the case may be, will be required to provide the certification
discussed above in order to establish an exemption from backup withholding tax and information reporting requirements. Moreover, a payor may rely on a certification provided by a payee that is not a
U.S. person only if such payor does not have actual knowledge or a reason to know that any information or certification stated in such certificate is incorrect.

Foreign Asset Reporting

Certain U.S. Holders who are individuals are required to report information relating to an interest in shares or ADSs, subject to
certain exceptions (including an exception for shares or ADSs held in accounts maintained by U.S. financial institutions). U.S. Holders are urged to consult their tax advisors regarding their
information reporting obligations, if any, with respect to their ownership and disposition of shares or ADSs.

The
above summary is not intended to constitute a complete analysis of all tax consequences that may be relevant to the acquisition, ownership and disposition of shares or ADSs, and does
not address state, local, foreign or other tax laws. Holders of shares or ADSs should consult their own tax advisors concerning the tax consequences of their particular situations.

Item 11:    Quantitative and Qualitative Disclosure about Market Risk

The global nature of AIXTRON's businesses exposes the Company to market risks resulting from changes in foreign currency exchange rate
and interest rates. Accordingly, changes in foreign currency exchange rates and interest rates may adversely affect its operating results and financial condition. AIXTRON seeks to manage and control
these market risks primarily through monitoring of its operating and financial activities and the use of derivative financial instruments.

Foreign Currency Exchange Rate Risk

Transaction Risk and Currency Risk

The global nature of AIXTRON's businesses exposes its operations and reported financial results and cash flows to the risks arising
from fluctuations in the exchange rates of the dollar, the Euro and other world currencies. AIXTRON's businesses are exposed to transaction risk whenever the Company has revenues in a currency that is
different from the currency in which it incurs the costs of generating those revenues. When AIXTRON converts the revenues into the currency in which it incurs the costs, the value of the revenues may
have declined in the interim relative to the currency in which the Company incurred the costs. The main billing currency in the semiconductor equipment industry, and therefore also for AIXTRON
equipment, continues to be the US-Dollar, while AIXTRON incurs manufacturing costs primarily in Euros.

Effects of Currency Translation

Most of AIXTRON's subsidiaries are located outside the Euro zone. Since the Company's presentation currency is the Euro, AIXTRON
translates the income statements of these subsidiaries into Euros so that the Company can include their financial results in its Consolidated Financial Statements.
Period-to-period changes in the exchange rate for a particular country's currency can significantly affect the translation of both revenues and operating income denominated in
that currency into Euros.

AIXTRON
has assets and liabilities outside the Euro zone. These assets and liabilities are denominated in local currencies and reside primarily at AIXTRON's subsidiaries in the United
States and the United Kingdom.

When
AIXTRON converts net asset values into Euros, currency fluctuations result in period-to-period changes in those net asset values. The Company's equity
position reflects these changes in net asset values. AIXTRON generally does not hedge against this type of risk.

Management of Foreign Currency Exchange Rate Risk

The Company's activities expose it to the financial risks of changes in foreign currency exchange rates. The Company enters into a
variety of derivative financial instruments to manage its exposure to foreign currency risk, including forward exchange contracts and options to hedge the exchange rate risk arising from the exporting
of equipment. The main exchange rates giving rise to the risk are those between the US-Dollar, pound sterling, and Euro.

The
Company's use of derivative financial instruments is governed by the Company's policies, approved by the Supervisory Board, which provide principles on foreign exchange rate risk and
the use of derivative financial instruments. Exposures are reviewed on a regular basis. The Company does not enter into derivative financial instruments for purely speculative purposes.

Exposure
to exchange rate risk is managed by the Company through sensitivity analysis. The following table details the Company's historical sensitivity to a 10% increase/decrease in the
value of the Euro against the principal foreign currencies involved.

This
represents AIXTRON's assessment of the possible change in foreign exchange rates. The sensitivity analysis of the Company's exposure to foreign currency risk at the reporting date
has been determined based on the change taking place at the beginning of the applicable financial year and sustained throughout such fiscal year, the effects of changes in the opening and closing
balance sheet

The sensitivity of the Company's net income to exchange rate risk is reduced, in comparison with the effect on revenue, by the use of foreign
currency exchange contracts and by the "natural hedge" effect of costs incurred in those currencies.

It
is the Company's policy to enter into foreign exchange contracts to cover specific foreign currency receipts generally within the range of 80 to 90% of the expected exposure. The
Company also enters into foreign exchange contracts to manage the risk associated with anticipated sales transactions, generally in the range of 15 months and generally within 50 to 60% of the
exposure generated.

Interest Rate Risk

The Company's income is subject to effects from interest rate fluctuations relating to interest rate influenced cash and cash
equivalents, short term investments and bank loans. During 2011, the Company received € 3.4 million (2010: € 2.8 million; 2009:
€ 1.3 million) of interest income.

Since
AIXTRON has no bank borrowings, the Company does not enter into derivative financial instruments to manage exposure to interest rate risks.

Refer
to Item 18 "Financial StatementsNote 26. Financial instruments" for more information on the credit, interest rate, and currency risks arising in
AIXTRON's normal course of business.

Item 12:    Description of Securities other than Equity Securities

On February 7, 2011, the deposit agreement dated March 10, 2005 with JPMorgan Chase Bank, N.A. ("JPMorgan"), as
depositary for the AIXTRON ADS program, was effectively replaced by a deposit agreement with The Bank of New York Mellon ("Bank of New York Mellon"), dated February 7, 2011.

As
provided for in the American Depositary Receipt included as Exhibit A to the amended and restated deposit agreement among AIXTRON, Bank of New York Mellon, as depositary (the
"Depositary") and all owners and holders of American Depositary Shares dated as of February 7, 2011, holders of American Depositary Shares may be charged, directly or indirectly, the following
amounts in relation to the ownership of depositary receipts held in the Company's ADS Program, which amounts are payable to the Depositary.

Disclosure Controls and Procedures

As of the end of the period covered by this report, Management of AIXTRON conducted an evaluation, under the supervision and with the
participation of AIXTRON's Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of AIXTRON's disclosure controls and procedures (as defined in
Rule 13a-15(e) under the Exchange Act).

Based
on such evaluation, AIXTRON's Chief Executive Officer Paul Hyland and Chief Financial Officer Wolfgang Breme have concluded that, as of December 31, 2011, AIXTRON's
disclosure controls and procedures are effective.

Management's Report on Internal Control over Financial Reporting

AIXTRON's Management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term
is defined in Rule 13a-15(f) under the Exchange Act, for AIXTRON. Under the supervision and with the participation of AIXTRON's Chief Executive Officer and Chief Financial Officer,
AIXTRON's Management conducted an evaluation of the effectiveness of AIXTRON's internal control over financial reporting based upon the framework in "Internal ControlIntegrated Framework"
issued by the Committee of Sponsoring Organizations of the Treadway Commission as of the end of the period covered by this report.

Based
on that evaluation, Management has concluded that AIXTRON's internal control over financial reporting was effective as of December 31, 2011.

Deloitte &
Touche GmbH, an independent registered public accounting firm, has audited the Consolidated Financial Statements included in this annual report on
Form 20-F and, as part of the audit, has issued an attestation report, included herein, on the effectiveness of AIXTRON's internal control over financial reporting.

Attestation Report of the Registered Public Accounting Firm

To
The Supervisory Board
AIXTRON SE
Herzogenrath, Germany

We
have audited the internal control over financial reporting of AIXTRON SE and subsidiaries (the "Company") as of December 31, 2011, based on criteria established in Internal
ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company's Management is responsible for maintaining effective internal
control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's report on internal control over
financial reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit.

We
conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over
financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing
such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A
company's internal control over financial reporting is a process designed by, or under the supervision of, the company's principal executive and principal financial officers, or persons performing
similar functions, and effected by the company's 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. A company's internal control over financial reporting 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 the assets of the company;
(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 of the company are being made only in accordance with authorizations of management and directors of the company; and (3) 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 the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to
error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are
subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In
our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2011, based on the criteria established in Internal
ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We
have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements as of and for the year ended
December 31, 2011 of the Company and our report dated February 28, 2012 expressed an unqualified opinion on those consolidated financial statements.

Changes in Internal Control over Financial Reporting

During the year ended December 31, 2011 there have been no changes in our internal control over financial reporting that have
materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations of Disclosure Controls and Procedures in Internal Control over Financial Reporting

It should be noted that any system of controls, however well-designed and operated, can provide only reasonable, and not
absolute, assurance that the objectives of the system will be met. In addition, the design of any control system is based in part upon certain assumptions about the likelihood of future events.

Item 16A:    Audit Committee Financial Expert

AIXTRON's Supervisory Board has determined that the Chairman of the Audit Committee Prof. Dr. Wolfgang Blättchen
is an "Audit Committee financial expert" and has determined that the "Audit Committee financial expert" is "independent" as set forth in Rule 10A-3 of the Exchange Act and NASDAQ
Rule 5605(a)(2). Prof. Dr. Wolfgang Blättchen is Chairman of the Audit Committee and acts as its independent financial expert since 2005.

Item 16B:    Code of Ethics

AIXTRON has adopted a Code of Ethics that applies to the members of the Company's Executive Board and senior financial officers
nominated by AIXTRON's Executive Board. All of these Executive Board members and senior financial officers have agreed to abide by this Code. The aim of the Code is to prevent misconduct and promote
upright and ethical conduct, including ethical handling of conflicts of interest, the complete, fair, precise, timely and transparent disclosure of quarterly and annual reports, compliance with
prevailing laws, rules and regulations, the immediate internal reporting of breaches of the Code and responsibility for compliance with the Code. AIXTRON's Code of Ethics, which is filed as an exhibit
to this annual report on Form 20-F, is consistent with the requirements of the NASDAQ Stock Market. The
Company has revised its Code of Ethics in 2007 and has published the updated version of the code on its website at www.aixtron.com. A copy of the Code of Ethics is available on the

Audit Committee Pre-Approval Policies

In accordance with German law, AIXTRON'S independent auditors are appointed at the Annual Shareholders' Meeting based on a
recommendation of the Company's
Supervisory Board. The Audit Committee of the Supervisory Board prepares the Board's recommendation on the selection of the independent auditors. Subsequent to the auditors' appointment, the
Supervisory Board awards the contract and in its sole authority approves the terms and scope of the audit and all audit engagement fees, as well as monitors the auditors' independence. On
May 19, 2011, at the Annual General Meeting of Shareholders, Deloitte & Touche GmbH Wirtschaftsprüfungsgesellschaft, Düsseldorf, Germany
("Deloitte & Touche") was appointed to serve as the Company's independent auditors for the year ending December 31, 2011.

In
order to assure the integrity of independent audits, AIXTRON's Audit Committee established a policy to approve all audit and permissible non-audit services provided by the
Company's independent auditors prior to the auditors' engagement. As part of this approval process, the Audit Committee adopted pre-approval policies and procedures pursuant to which the
Audit Committee annually pre-approves certain types of services to be performed by AIXTRON's independent auditors. Under the policies, the Company's independent auditors are not allowed to
perform any non-audit services which may impair the auditors' independence under the rules of the SEC. In fiscal year 2011 the Audit Committee pre-approved 100% of the
performance by Deloitte & Touche of the above specified audit and permitted non-audit services.

Report of Independent Registered Public Accounting Firm

To
The Supervisory Board
AIXTRON SE
Herzogenrath, Germany

We
have audited the accompanying consolidated statement of financial position of AIXTRON SE and subsidiaries (the "Company") as of December 31, 2011 and 2010, and the related
consolidated income statement, consolidated statement of other comprehensive income, consolidated statement of cash flow, and consolidated statement of changes in equity for each of the three years in
the period ended December 31, 2011. These consolidated financial statements are the responsibility of the Company's Management. Our responsibility is to express an opinion on the consolidated
financial statements based on our 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 audit to
obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by Management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our opinion.

In
our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of AIXTRON SE and subsidiaries as of December 31, 2011 and
2010, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2011, in conformity with International Financial Reporting Standards
as issued by the International Accounting Standards Board (IASB).

We
have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company's internal control over financial reporting as of
December 31, 2011, based on the criteria established in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our
report dated February 28, 2012 expressed an unqualified opinion on the Company's internal control over financial reporting.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

1.     General Principles

AIXTRON SE is incorporated as a European Company (Societas Europaea) under the laws of the Federal Republic of Germany. The Company is domiciled at Kaiserstraße 98,
52134Herzogenrath, Germany. AIXTRON SE is registered in the commercial register of the District Court ("Amtsgericht") of Aachen under HRB 16590.

The
consolidated financial statements of AIXTRON SE and its subsidiaries ("AIXTRON"or "Company") have been prepared in accordance with, and fully comply with



AIXTRON
is a leading provider of deposition equipment to the semiconductor and compound-semiconductor industry. The Company's technology solutions are used by a diverse range of
customers worldwide to build advanced components for electronic and opto-electronic applications based on compound, silicon, or organic semiconductor materials. Such components are used in
fibre optic communication systems, wireless and mobile telephony applications, optical and electronic storage devices, computing, signalling and lighting, displays, as well as a range of other
leading-edge technologies.

These
consolidated financial statements have been prepared by the Executive Board and have been submitted to the Supervisory Board at its meeting held on February 29, 2012 for
approval and publication.

2.     Significant Accounting Policies

(a)   Companies included in consolidation

Companies included in consolidation are the parent company, AIXTRON SE, and 8 companies, in which AIXTRON SE has a 100% direct shareholding or control. The
balance sheet date of all consolidated companies is December 31. A list of all consolidated companies is shown in note 31.

(b)   Basis of accounting

The consolidated financial statements are presented in Euro (EUR). The amounts are rounded to the nearest thousand Euro (kEUR). Some items in the statement of
financial position and income statement have been combined under one heading to improve the clarity of presentation. Such items are disclosed and commented on individually in the notes.

The
financial statements have been prepared on the historical cost basis, except for the revaluation of certain financial instruments.

The
preparation of financial statements in conformity with IFRS 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 balance sheet date and the reported amounts of income and expenses during the reported period. Actual results may differ from these estimates.

The
estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognised in the period in which the estimate is revised if this
revision affects only that period, or in the period of the revision and future periods if the revision affects both current and future periods. Judgments which have a significant effect on the
Company's financial statements are described in Note 37.

The
accounting policies set out below have been applied consistently to all periods presented in these consolidated financial statements.

The
accounting policies have been applied consistently by each consolidated company.

(c)   Bases of consolidation







(d)   Foreign currency

The consolidated financial statements have been prepared in Euro (EUR). In the translation of financial statements of subsidiaries outside the
Euro-Zone the local currencies are used as functional currencies of those companies. Assets and liabilities of those companies are translated to EUR at the exchange rate ruling at the
balance sheet date. Revenues and expenses are translated to EUR at average exchange rates for the year or at average exchange rates for the period between their inclusion in the consolidated financial
statements and the balance sheet date. Net equity is translated at historical rates. The differences arising on translation are disclosed in Consolidated Statement of Changes in Equity.

Exchange
gains and losses resulting from fluctuations in exchange rates in the case of foreign currency transactions are recognised in the income statement in "other operating income"or
"other operating expenses".

(h)   Inventories

Inventories are stated at the lower of cost and net realisable value. Net realisable value is the estimated selling price in the ordinary course of business, less
the estimated cost of completion and selling expenses. Cost is determined using weighted average cost.

The
cost includes expenditures incurred in acquiring the inventories and bringing them to their existing location and condition. In the case of work in progress and finished goods, cost
includes direct material and production cost, as well as an appropriate share of overheads based on normal operating capacity.

Allowance
for slow moving, excess and obsolete, and otherwise unsaleable inventory is recorded based primarily on either the Company's estimated forecast of product demand and production
requirement for the next twelve months or historical trailing twelve month usage. When there has been

no
usage of an inventory item during a period of twelve months, the Company writes down such inventories based on previous experience.

(i)    Operating Result

Operating result is stated before finance income, finance expense and tax.

(j)    Impairment of property, plant and equipment and intangible assets

Goodwill purchased as part of a business acquisition is tested annually for impairment, irrespective of whether there is any indication of impairment. For
impairment test purposes, the goodwill is allocated to cash-generating units. Impairment losses are recognised to the extent that the carrying amount exceeds the higher of net realisable
value or value in use (recoverable amount) of the cash-generating unit.

Property,
plant and equipment as well as other intangible assets are tested for impairment, where there is any indication that the asset may be impaired. The company assesses at the end
of each period whether there is an indication that an asset may be impaired. Impairment losses on such assets are recognised, to the extent that the carrying amount exceeds either thefair value less
cost to sell, or the value in use.

In
assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments and
the risks associated with the asset.

Impairment
losses are reversed if there has been a change in the estimates used to determine the recoverable amount. Reversals are made only to the extent that the carrying amount of the
asset does not exceed the carrying amount that would have been determined if no impairment loss had been recognised.

An
impairment loss in respect of goodwill is not reversed.

(k)   Earnings per share

Basic earnings per share are computed by dividing net income (loss) by the weighted average number of issued common shares (see note 21) for the year.
Diluted earnings per share reflect the potential dilution that could occur if options issued under the Company's stock option plans were exercised and convertible bonds were converted, unless such
conversion had an anti-dilutive effect.

(l)    Employee benefits

2.     Significant Accounting Policies (Continued)



(m)  Provisions

A provision is recognised when the Company has a present legal or constructive obligation as a result of a past event, and it is probable that an outflow of
economic benefits will be required to settle this obligation. If the effect is material, provisions are determined by discounting the expected future cash flows at a pre-tax interest rate
that reflects current market assessments of the time value of money and, where appropriate, the risks associated with the liability.





(n)   Revenue

Revenue is generated from the sale and installation of equipment, spare parts and maintenance services. The sale of equipment involves a customer acceptance test
at AIXTRON?s production facility. After successful completion of this test, the equipment is dismantled and packaged for shipment. Upon arrival at the customer site the equipment is
reassembled and installed, which is a service generally performed by AIXTRON engineers. AIXTRON gives no general rights of return, discounts, credits or other sales incentives within its terms of
sale. However, occasionally some customers of AIXTRON have specifically negotiated terms and conditions of business.

Revenues
from the sale of products that have been demonstrated to meet product specification requirements are recognised upon shipment to the customer, if a full customer acceptance test
has been successfully completed at the AIXTRON production facility and the significant risks and rewards of ownership has passed to the customer.

Revenue
relating to the installation of the equipment at the customer's site is recognised when the installation is completed and the final customer acceptance has been confirmed. The
portion of the contract revenue deferred until completion of the installation services is determined based on either the fair value of the installation services or, if the company determines that
there may be a risk that the economic benefits of installation services may not flow to the company, the portion of the contract

amount
that is due and payable upon completion of the installation. Fair value of the installation services is determined based on market rates for the materials and time required to complete the
installation.

Revenue
related to products where meeting the product specification requirements has not yet been demonstrated, or where specific rights of return have been negotiated, is recognised
only upon final customer acceptance.

Revenue
on the sale of spare parts is recognised when title and risk passes to the customer, generally upon shipment. Revenue from maintenance services is recognised as the services are
provided.

(o)   Expenses





(p)   Other operating income

Government grants

Government grants awarded for project funding are recorded in "Other operating income" if the Research and Development costs are
incurred and provided that the conditions for the funding have been met.

(q)   Tax

The tax expense represents the sum of the current and deferred tax.

Deferred
tax assets and liabilities are recorded for all temporary differences between tax and commercial balance sheets and for losses brought forward for tax purposes as well as for
tax credits of the companies included in consolidation. The deferred taxes are calculated, based on tax rates
applicable at the balance sheet date or known to be applicable in the future. Effects of changes in tax rates on the deferred tax assets and liabilities are recognised upon substantively enacted
amendments to the law.

A
deferred tax asset is recognised only to the extent that it is probable that future taxable profits can be set off against tax credits and tax losses carried forward. Deferred tax
assets are reduced to the extent that it is no longer probable that the related tax benefit can be realised. The recoverability of deferred tax assets is reviewed at least annually.

(r)   Segment reporting

An operating segment is a distinguishable component of the Company that is engaged in business activities and whose operating results are reviewed regularly by
the Chief Operating Decision Maker, which the Company considers to be its Executive Board. The Executive Board regularly reviews financial information on a consolidated group basis. Aixtron has only
one reportable segment.

2.     Significant Accounting Policies (Continued)

Accounting
standards applied in segment reporting are in accordance with the general accounting policies as explained in this section.

(s)   Cash flow statement

The cash flow statement is prepared in accordance with IAS 7. Cash flows from operating activities are prepared using the indirect method. Cash inflows and
cash outflows from taxes and interest are included in cash flows from operating activities.

(t)    Recently issued accounting standards

Amendments to the following standards and interpretations were adopted during 2011:



The
adoption of these interpretations and amended standards has not led to any changes in the company's accounting policies. The standards, amendments to standards and interpretations
have all been adopted earlier than required.

At
the date of authorisation of these financial statements, the following Standards and amendments to Standards, which havenot been applied in these financial statements, were in issue
but not yet effective and not yet adopted by the EU.



The
adoption of IFRS 9 which the Company plans to adopt on 1st January 2015 will impact both the measurement and disclosures of Financial Instruments; other
changes to standards do not have a material impact.

3.     Segment Reporting

IFRS 8
requires operating segments to be identified on the basis of internal reports about components of the Group that are regularly reviewed by the Executive Board, as chief
operating decision maker, in order to allocate resources to the segments and to assess their performance.

3.     Segment Reporting (Continued)

The Executive Board regularly reviews financial information on a consolidated group basis since the various activities of the group are largely integrated from an operational
perspective. In accordance with IFRS 8.5, AIXTRON has only one reportable segment.

The
company's reportable segment is based around the category of goods and services provided to the semiconductor industry.

At the end of 2011 the Group assessed the recoverable amount of goodwill and determined that no impairment loss had to be recognized
(2010: k€  0; 2009 k€ 0).

The
carrying value of goodwill was k€ 64,078 (2010 k€ 62,201; 2009 k€ 58,275). The addition in the
year of k€ 234 is a further contractual payment to the former owners of Nanoinstruments Ltd. Nanoinstruments Ltd was acquired by AIXTRON Ltd in 2007.

As
at the end of 2011 the cash generating unit, to which the goodwill has been allocated, is the Aixtron Group operational segment.

The
recoverable amount of the cash-generating unit is determined through a fair value less cost to sell calculation which uses cash flow projections based on financial
budgets and forecasts approved by the Executive Board covering the period up to 2013. Management has carried out checks to ensure that its internal projections are consistent with external forecasts
of sales and earnings.



The
directors believe that any reasonably possible change in the key assumptions on which recoverable amount is based would not cause the aggregate carrying amount to exceed the
aggregate amount recoverable from the cash-generating unit.

Deferred
tax assets are recognised at the level of individual consolidated companies in which a loss was realised in the current or preceding financial year, only to the extent that
realisation in future periods is probable. The nature of the evidence used in assessing the probability of realisation includes forecasts, budgets and the recent profitability of the relevant entity.
The carrying amount of deferred tax assets for entities which have made a loss in either the current or preceding year was k€ 142 (2010:
k€ 3,180). Forecast transactions are expected to give rise to taxable profits in 2012 in the entity where deferred tax assets have been recognised.

Deferred
taxes for tax losses in the amount of k€ 16,141 (2010: k€ 17,056) and on deductible temporary differences in the amount
of k€ 886 (2010: k€ 22,028) were not recognised. Tax losses in the amount of k€ 0 can be used indefinitely (2010:
k€ 0), k€ 1,341 expire by 2016 (2010: 0, by 2015) and k€ 14,800 expire after 2016 (2010:
k€ 17,056 after 2015).

Additions
to allowances on trade receivables are included in other operating expenses, releases of allowances are included in other operating income.

Due
to the worldwide spread of risks, there is a diversification of the credit risk for trade receivables. Generally, the Company demands no securities for financial assets. In
accordance with usual business practice for capital equipment however, the Company mitigates its exposure to credit risk by requiring payment by irrevocable letters of credit and substantial payments
in advance from most customers as conditions of contracts for sale of major items of equipment.

At
the balance sheet date two customers accounted for 26% and 23% respectively of the company's net trade receivables, no other single customer accounted for more than 10% of trade
receivables. In 2010 one customer accounted for 11% of trade receivables, no other customer accounted for more than 10% of receivables. In determining concentrations of credit risk the company defines
counterparties as having similar characteristics if they are connected entities.

Included
in the Company's trade receivable balance are debtors with a carrying amount of k€ 4,602 (2010: k€ 12,807) which are
past due at the reporting date for which the Company has not provided. As there has not been a significant change in credit quality and, although the company has no collateral, the amounts are still
considered recoverable.

In
determining the financial assets which may be individually impaired the Company has taken into account the likelihood of recoverability based on the past due nature of certain
receivables, and our assessment of the ability of all counter-parties to perform their obligations.

18.   Other financial assets

Other financial assets of k€ 122,323 (2010: k€ 202,587) are fixed deposits with banks with a maturity of more than three months

22.   Employee benefits

Defined contribution plan

The Company grants retirement benefits to qualified employees through various defined contribution pension plans. The expenses incurred
for defined contribution plans mainly arise from two pension plans in subsidiaries. The contributions made do not exceed 10% of qualified employees' base salaries. In 2011 the expense recognised for
defined contribution plans amounted to k€ 1,338 (2010: k€ 1,152, 2009: k€ 970). In addition to the Company's
retirement benefit plans, the company is required to make contributions to
state retirement benefit schemes in most of the countries in which it operates. The company is required to contribute a specified percentage of payroll costs to the retirement schemes in order to fund
the benefits. The only obligation of the group is to make the required contributions.

Defined benefit plan

The Company's net obligation in respect of defined benefit pension plans reflects commitments to two former members of the Executive
Board of AIXTRON SE. These are final salary plans.

In
the three years ending 2011 no payments were made under these plans. The value of the obligations from pension plans is determined annually at December 31. During 2010 these
obligations

23.   Share-based payment

The Company has different fixed option plans which reserve shares of common stock and AIXTRON American Depository Shares (ADS) for issuance to members of the Executive Board, management
and employees of the Company. Each AIXTRON ADS represents the beneficial ownership in one AIXTRON common share. The following is a description of these plans:

AIXTRON stock option plan 1999

In May 1999, options were authorized to purchase 3,000,000 shares of common stock (after giving effect to capital increases, stock
splits, and the EURO conversion). The stock options can be exercised when 15 years have elapsed since their issue. Under the terms of the 1999 plan, options were granted at prices equal to the
average closing price over the last 20 trading days on the Frankfurt Stock Exchange before the grant date. Under this plan 1,113,567 options for the purchase of 1,781,044 common shares were
outstanding as of December 31, 2011.

AIXTRON stock option plan 2002

In May 2002, options were authorized to purchase 3,511,495 shares of common stock. The options are exercisable in equal instalments of
25% per year after the second anniversary of the date of grant, subject to certain conditions. Options expire ten years from date of grant. Under the terms of the 2002 plan, options are granted at
prices equal to the average closing price over the last 20 trading days on the Frankfurt Stock Exchange before the grant date, plus 20%. No grants were issued with a strike price less than fair market
value. A total of 394,209 options to purchase the same number of common stock were outstanding under this plan as of December 31, 2011.

AIXTRON stock option plan 2007

Options were granted to purchase shares of common stock. 50% of the granted options may be executed after a waiting period of not less
than two years, further 25% after three years and the remaining 25% after at least four years. The options expire 10 years after they have been granted. Under the terms of the 2007 plan,
options are granted at prices equal to the average closing price over the last 20 trading days on the Frankfurt Stock Exchange before the grant date, plus 20%.

Assumptions used to calculate fair values and share-based payment expenses

The fair value of services received in return for stock options granted is measured by reference to the fair value of the stock options
granted. The fair value of the stock options is determined on the basis of a binomial lattice model. In accordance with IFRS 2 the measurement includes only options which were granted after
November 7, 2002. In 2011, the personnel expenses from share-based payments were k€ 5,064 (2010: k€ 3,645; 2009:
k€ 2,149). As of December 31, 2011 an amount of k€ 6,308 relating to stock options granted prior to that date had not yet been
recognised as a personnel expense. This amount will be charged over the period to 2016. The expected allocation of the expense is as follows: 2012: k€ 3,775, 2013:
k€ 1,825, 2014 k€ 623, 2015: k€ 85 and 2016: k€ 1.

The

within 90 days of receipt of the relevant goods or services. The maturities of currency contracts are shown in Note 26.

26.   Financial Instruments

Details of the significant accounting policies and methods, the basis of measurement that are used in preparing the financial statements and the other accounting policies that are
relevant to an understanding of the financial statement are disclosed in note 2 to the financial statements.

Financial risk management objectives

The group seeks to minimise the effects of any risk that may occur from any financial transaction. Key aspects are the exposures to
liquidity risk, credit risk, interest rate risk and currency riskarising in the normal course of the Company's business.

The
AIXTRON Group's central management co-ordinates access to domestic and international financial institutions and monitors and manages the financial risks relating to the
operations of the Group through internal risk reports which analyse exposure to risk by likelihood and magnitude. These risks cover all aspects of the business, including financial risks; and the risk
management system is in accordance with the corporate governance recommendations specified in the German Corporate Governance Code.

Derivative
financial instruments are used to hedge exposure to fluctuations in foreign exchange rates.

Liquidity risks

Liquidity risk is the risk that the Group is unable to meet its existing or future obligations due to insufficient availability of cash
or cash equivalents. Managing liquidity risk is one of the central tasks of AIXTRON SE. In order to be able to ensure the Group's solvency and
flexibility at all times cash and cash equivalents are projected on the basis of regular financial and liquidity planning.

As
at December 31, 2011 the group had no borrowings (2010 nil). Financial liabilities, all due within one year, of k€ 40,603 (2010
k€ 43,677) consisting of trade payables and other liabilities and are shown in Note 25, together with an analysis of their maturity. As at December 31, 2011
the group had k€ 172,892 cash and cash equivalents (2010 k€ 182,118) and a further k€ 122,323 of fixed deposits
with banks (2010 k€ 202,587).

F-34

Table of Contents

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)

26.   Financial Instruments (Continued)

Credit risks

Financial assets generally exposed to a credit risk are trade receivables (see note 17) and cash and cash equivalents.

The
Group's cash and cash equivalents are kept with banks that have a good credit standing. Central management of the Group assesses the counter-party risk of each financial institution
dealt with and sets limits to the Group's exposure to those institutions. These credit limits are reviewed from time to time so as to minimise the default risk as far as possible and to ensure that
concentrations of risk are managed. The maximum exposure of the Group to credit risk is the total amount of receivables, financial assets and cash balances as described in notes 17, 18 and 19.

Market risks

The Company's activities expose it to the financial risks of changes in foreign currency exchange rates and interest rate risks.
Interest rate risks are not material as the company only receives a minor amount of interest income. The Company does not use derivative financial instruments to manage its exposure to interest rate
risk. Cash deposits are made with the company's bankers at the market rates prevailing at inception of the deposit for the period and currency concerned. There has been no change to the Company's
exposure to market risk or the manner in which it manages and measures the risk.

Foreign currency risk

The Company enters into a variety of derivative financial instruments to manage its exposure to foreign currency risk, including
forward exchange contracts to hedge the exchange rate risk arising on the export of equipment. The main exchange rates giving rise to the risk are those between the US Dollar, Pound Sterling and Euro.

The
carrying amounts of the Group's foreign currency denominated monetary assets and monetary liabilities at the reporting date are as follows:

Exposures
are reviewed on a regular basis and are managed by the Company through sensitivity analysis.

Foreign currency sensitivity analysis

The Company is mainly exposed to US Dollar exchange rate risks through its worldwide activities.

The
following table details the company's sensitivity to a 10% change in the value of the Euro against the Dollar. A positive number indicates an increase in profit and other equity, a
negative number indicates a reduction in profit and other equity.

The effect on profit or loss of changes in currency rates differs between increases and decreases in rates because of the asymmetrical effect of
changes in valuation of option contracts.

The
sensitivity analysis represents the foreign exchange risk at the year-end date only. It is calculated by revaluing the Group's financial assets and liabilities, existing
at 31 December, denominated in US-Dollars by 10%. It does not represent the effect of a 10% change in exchange rates sustained over the whole of the financial year, only the effect
of a different rate occurring on the last day of the year.

Forward foreign exchange contracts

The company enters forward foreign exchange contracts with banks to cover receipts from highly probable forecast sales denominated in
US Dollars.

The
following table details the forward foreign currency contracts outstanding as at the reporting date:

Foreign currency cash flow hedges

As of 31st December 2011, the aggregate amount of unrealised gains (2010: losses) on forward foreign exchange contracts deferred
in the hedging reserve relating to the exposure on anticipated future transactions is k€ 6,438 (2010: k€ 340).

The
unrealised losses of k€ 340 (31 December 2009: k€ 1,115) included in income and expenses recognised in equity as of

at maturity date of the contracts in the financial year. The gains actually realised in 2011 were kEUR6,874 (2010: losses k€ 7,951).

Foreign currency option contracts

The company has also entered into option contracts to hedge the exchange rate risk on US Dollar sales proceeds in 2012. The contracts
are classified as at fair value through the profit and loss account.

Unrealised
lossesof k€ 5,461 (2010 gain: k€ 610) on forward exchange contracts are recognised in Other Operating Expense (2010
Other Operating Income) in the Income Statement.

At
December 31, 2011 AIXTRON held a series of US dollar/ Euro put and call options with equal and opposite purchase and sales volumes and maturities. In view of the expectation
that the intrinsic value of these options will be offsetting, and to the extent that they represent hedges of highly probable future cash flows, they have been designated as cash flow hedges and
accounted for as such in accordance with IAS 39.

Fair values

Cash and cash equivalents, Loans and receivables and Held to maturity investments are stated at amortised cost. At FVTPL and Hedging
derivatives are classed as at fair value through profit or loss.

fair values and the carrying amounts of the financial instruments shown in the balance sheet are shown in the following table. Financial assets are classified into categories.

The fair value is the amount for which an asset could be exchanged, or a liability settled, between knowledgeable, willing parties in
an arm's length transaction. The values are derived from inputs other

than
quoted prices that are observable for the asset or liability either directly (as prices) or indirectly (derived from prices). This is level 2 in the hierarchy of fair value measurement
techniques.

Trade receivables/payables

For trade receivables/payables due within less than one year, the fair value is taken to be the nominal value. All other
receivables/payables are discounted to determine the fair value.

27.   Operating leases

Leases as lessee

Non-cancellable operating lease rentals are payable as follows:

The
Company leases certain office and plant facilities, office furniture and motor vehicles under various operating leases. Under most of the lease commitments for office and plant
facilities the Company has options to renew the leasing contracts. The leases typically run for a period between one and fifteen years. None of the leases include contingent rentals.

The
expenses for leasing contracts were k€ 4,490, k€ 3,959 and k€ 2,922 for 2011, 2010 and 2009
respectively

28.   Capital commitments

As of December 31, 2011, the Company had entered into purchase commitments with suppliers in the amount of k€ 84,757 (2010:
k€ 92,277) for purchases within the
next 12 months. Commitments for capital expenditures are k€ 4,164 (2010: k€ 6,514) as of December 31, 2011.

29.   Contingencies

The Company is involved in various legal proceedings or can be exposed to a threat of legal proceedings in the normal course of business. The Executive Board regularly analyses these
matters, considering any possibilities of avoiding legal proceedings or of covering potential damages under insurance contracts and has recognised, where required, appropriate provisions. It is not
expected that such matters will have a material effect on the Company's net assets, results of operations and financial position.

The
legal proceeding issued in 2008 between International Rectifier Corporation ("I.R."), of El Segundo, California, USA and AIXTRON SE was settled by agreement in January 2011. I.R.
withdrew its action and financial claims against Aixtron in exchange for certain disclosures and witness statements provided by AIXTRON. At I.R's request the Court dismissed the action against
AIXTRON. No further liability exists.

37.   Critical accounting judgments and key sources of estimation and uncertainty

The preparation of AIXTRON's Consolidated Financial Statements requires the Company to make certain estimates, judgments and assumptions that the Company believes are reasonable based
upon the information available. These estimates and assumptions affect the reported amounts and related disclosures and are made in order to fairly present the Company's financial position and results
of operations. The following accounting policies are significantly impacted by these estimates and

37.   Critical accounting judgments and key sources of estimation and uncertainty (Continued)

judgments
that AIXTRON believes are the most critical to aid in fully understanding and evaluating its reported financial results include the following:

Revenue
Recognition

Revenue
is generally recognised in two stages for the supply of equipment to customers, partly on delivery and partly on final installation and acceptance (see
note 2 (n)). The Company believes, based on past experience, that this method of recognising revenue fairly states the revenues of the Company. The judgements made by management include an
assessment of the point at which substantially all of the risks and rewards of ownership have passed to the customer.

Goodwill

As
stated in the accounting policies, the Company tests at least annually whether goodwill has suffered impairment. If there is an indication of impairment,
the recoverable amount of the cash generating unit has to be estimated. This is the greater of the fair value less costs to sell and the value in use. The determination of the value in use involves
making judgements and estimates related to the projection and discounting of future cash flows. Although the Company
believes the assumptions used to calculate recoverable amount are appropriate, any unforeseen changes in these assumptions could result in impairment charges to goodwill which could adversely affect
the future financial position and operating results. The carrying amount of goodwill is disclosed in note 12.

Valuation
of Inventories

Inventories
are stated at the lower of cost and net realisable value. This requires the Company to make judgments concerning obsolescence of materials. This
evaluation requires estimates, including both forecasted product demand and pricing environment, both of which may be susceptible to significant change. The carrying amount of inventories is disclosed
in note 16.

In
future periods, write-downs of inventory may be necessary due to (1) reduced demand in the markets in which the Company operates, (2) technological obsolescence due to
rapid developments of new products and technological improvements, or (3) changes in economic or other events and conditions that impact the market price for the Company's products. These
factors could result in adjustment to the valuation of inventory in future periods, and significantly impact the Company's future operating results.

Income
Taxes

At
each balance sheet date, the Company assesses whether the realisation of future tax benefits is sufficiently probable to recognise deferred tax assets. This
assessment requires the exercise of judgement on the part of management with respect to future taxable income. The recorded amount of total deferred tax assets could be reduced if estimates of
projected future taxable income are lowered, or if changes in current tax regulations are enacted that impose restrictions on the timing or extent of the Company's ability to utilize future tax
benefits. The carrying amount of deferred tax assets is disclosed in note 14.
