Interim Management Report //

Important Factors of the Reporting Period Q3/2011

Macro-economic environment

• // The risks to global financial stability have increased significantly in recent months, with predictions of slower economic growth being announced by several expert institutions. The global concern over the Euro debt crisis has escalated and consequently increased the turbulence within the financial markets. Coupled with the credit downgrades of several countries, including the United States, all of these factors have generated a sense of uncertainty across the entire global financial system.
• // Virtually all stock markets have suffered significantly from these macro-economic developments. The MSCI World Index has decreased by 17%, the German DAX30 Index has dropped by 25%, the TecDAX30 Index by 26% and the AIXTRON shares by 53%.

US Dollar – Euro development

• // Towards the end of the third quarter, the value of the Euro depreciated against the US Dollar on continued concerns about the European debt crisis and about the stability of the European monetary union. The USD/EUR exchange rate fell below the 1.40 USD/EUR mark on September 8, to end the quarter at 1.34 USD/EUR which represents a change of almost 8% against the USD/EUR exchange rate at the end of the previous quarter (June 30, 2011: 1.45 USD/EUR).
• // The strengthening of the US Dollar towards the end of the period led to a EUR 12.4m expense of currency hedging and translation effects in the quarter-end mark-to-market of pending hedging instruments and customer deposits as of June 30, 2011.
• // However, the average exchange rate used by AIXTRON for the income and expenses of Q3/2011 was 1.44 USD/EUR, almost unchanged from the previous quarter's booking rate (Q2/2011: 1.45 USD/EUR), resulting in no significant sequential currency impact on revenues.

Financing and margin pressures for LED manufacturers

// During the reporting quarter, the previously high investment activities by Asian LED manufacturers, driven by substantial government funding, have become restrained by an unscheduled but significant slowdown in demand. This partially resulted from insufficiently developed end-market demand, but is also evidence of some financing pressures on the Asian LED manu facturers, including increasing credit tightness in this region.

• // In this context, discussions with some of AIXTRON's Asian LED customers have revealed an increasing concern about the short-term fragility of the global economic recovery, evidenced by slowing demand in the TV backlighting market, where, in all likelihood, the quantity of LED manufacturing equipment installed already represents close to 80% of the projected total equipment requirement for this end market. One consequence of these market developments has been that the end market prices for LEDs have declined, by up to 15% over the quarter, leading to evident margin pressures for Asian LED makers.
• // Whilst the vast majority of AIXTRON's revenues traditionally come from Asia (86% in Q3/2011; 90% in Q2/2011; 92% in Q3/2010), significant shifts between the different Asian revenue regions have recently taken place, with China having become the Company's most important revenue driver.
• // Despite the current market correction to the very aggressive growth targets being pursued in the Asian region, and the consequent reassessment of capacity investment plans by Asian LED manufacturers, AIXTRON Management still believes that the mid- to long-term LED market opportunities will materialize. Management remains convinced that the development of a sustainable LED lighting industry will follow this temporary period of uncertainty and that, in conjunction with government initiatives such as the Chinese 5 year plan or the Korean 60/20 Plan the positive outlook for the LED industry and AIXTRON remains in place.

Revision of full-year guidance due to customer investment restraints

• // On September 15, 2011, AIXTRON issued a revised 2011 revenue and EBIT guidance of EUR 600m – 650m of revenues and an EBIT performance of circa 25 – 30%.
• // Management also reviewed the equipment order backlog and decided, as a matter of prudence, to reduce the previously published order backlog of EUR 373.5m by EUR 100m. This backlog and guidance adjustment took into account AIXTRON's Management opinion on conversion risk, purchase order delays and deferred system delivery requests by several customers, specifically in Asia.
• // These adjustments represent a set-back for AIXTRON's original full year targets, but reflect the previously described market challenge.
• // AIXTRON has already initiated cost reduction measures, so that the margin effect of reduced shipping volumes is minimized.

Revenue development and profitability affected by global market uncertainty

// Quarterly revenues decreased by 49% sequentially from EUR 175.6m in Q2/2011 to EUR 89.8m in Q3/2011. In a year on year comparison, they were 58% lower (Q3/2010: EUR 212.7m). This sudden decrease in revenues is principally down to a small number of significant customer delayed deliveries, which are also reflected in the order backlog adjustments of September 15th.

• // The Company's gross margin decreased sequentially by 1 percentage point, from 43% (EUR 76.9m) in Q2/2011 to 43% (EUR 38.7m) in Q3/2011. In Q3/2010, the gross profit recorded was EUR 110.6m in absolute terms or 52% of sales. The sequential decrease by comparison was mainly due to the revenue decline in Q3/2011.
• // The Q3/2011 EBIT came in slightly above break-even, at EUR 0.6m with a 1% EBIT margin (Q2/2011: EUR 54.3m or 31% margin; Q3/2010: EUR 82.6m or 39% margin). This EBIT decline is largely due to the lower revenues at the previously planned cost base and due to negative exchange rate revaluation effects in the third quarter of 2011.
• // For the third quarter of 2011, AIXTRON equipment order intake amounted to EUR 51.5m, which was 77% less than in Q2/2011 (EUR 222.2m) and 74% lower in a year on year comparison (Q3/2010: EUR 200.4m), predominantly due to the macro and market conditions described beforehand.

Launch of CRIUS® II-L

• // In July 2011, AIXTRON launched a larger version of the CRIUS® II MOCVD system; the CRIUS® II-L setting new benchmarks for MOCVD reactor capacity, throughput and LED production cost. What is now the world's largest capacity throughput MOCVD reactor, the CRIUS® II-L is configurable as either a 3x8 inch, a 7x6 inch, 16x4 inch or a 69x2 inch wafer system and is offered as a variant of the already market proven CRIUS® II platform, thereby allowing customers a seamless transfer of their qualified high performance LED processes.
• // The reduction of manufacturing costs is a key issue in today's LED industry and CRIUS® II-L offers unsurpassed capacity and throughput, combined with an outstanding yield due to its excellent uniformity and reproducibility.
• // AIXTRON has already received very positive customer response to this new product release, supporting the Management's confidence in the positive mid- to long-term growth perspectives of the LED lighting industry and AIXTRON's contribution to that growth.

Research project "HiPoSwitch" for GaN-based high power switching transistors approved

• // In Q3/2011, the HiPoSwitch joint research project, funded by the EU, was formally approved and started. The project consortium comprises eight participants, with AIXTRON being one of four industry partners. Through a coordinated approach, the members of the consortium are focused on the development of highly efficient Gallium Nitride (GaN) based power devices using silicon as the substrate material.
• // This new development has the potential to significantly decrease the components' size and weight by increasing the conversion efficiency of the devices, while also increasing their lifetime. The most promising potential for GaN-on-Silicon power electronic devices are perceived to be in the fields of telecommunication, IT, consumer electronics, automotive and industrial applications.
• // The French market analyst, Yole Developpement, forecasts the initial market development for GaN devices in early 2012 leading to an estimated USD 50m total addressable market size by 2013 and approximately USD 350m by 2015.

Interim Management Report // Results of Operations

Development of Revenues

Quarterly revenues decreased by 49% sequentially from EUR 175.6m in Q2/2011 to EUR 89.8m in Q3/2011. In a year on year comparison, they were 58% lower (Q3/2010: EUR 212.7m). This sudden decrease in revenues was principally due to a small, number of significant customer delayed deliveries that reflected a market correction at the very aggressive growth targets being pursued in the Asian region. Some macro-economic factors, including the growing uncertainty about financial stability, also had an influence on the recent revenue development.

During the first nine months of 2011, AIXTRON recorded cumulated revenues of EUR 470.8m, a decrease of EUR 88.3m, or 16%, compared to EUR 559.1m in the same period last year.

Equipment revenues, excluding spares and service, were EUR 77.0m in Q3/2011 and EUR 428.2m in 9M/2011 (9M/2010: EUR 523.7m), which represents 86% and 91% of the total Q3 and 9M/2011 revenues (9M/2010: 94%). The equipment AIXTRON sells is mainly used by customers for the production of LEDs for consumer electronics products and, to an increasing extent, for emerging lighting applications. The year on year decrease in equipment revenues is mainly due to the recent customer delayed deliveries by Asian LED manufacturers.

The remaining revenues were generated by sales of spare parts and service, accounting for 14% and 9% of total revenues in Q3/2011 and 9M/2011 (9M/2010: 6%).

	9M/2011		9M/2010		9M-9M

Revenues by equipment, spares & service

86% of total Q3/2011 revenues (Q3/2010: 92%) and 89% of total revenues in the first nine months of 2011 (9M/2010: 93%) were generated by sales to customers in Asia.

4% of revenues in Q3/2011 were generated in Europe (Q3/2010: 3%) and the remaining 10% in the USA (Q3/2010: 5%). In the first nine months of 2011, 4% of revenues were generated in Europe (9M/2010: 3%) and the remaining 7% in the USA (9M/2010: 4%).

In Q3/2011, while revenues were 49% down sequentially and 58% down year on year, the absolute cost of sales were reduced by 48% sequentially and 50% year on year and amounted to EUR 51.2m (Q2/2011: EUR 98.8m; Q3/2010: EUR 102.1m). Year on year, the currency effect on revenues was the major reason for the recorded higher percentage of cost of sales of 57% in Q3/2011 (56% in Q2/2011; 48% in Q3/2010).

In a nine months comparison, cost of sales decreased year on year, by 5% from EUR 264.6m in 9M/2010 to EUR 251.2m. Cost of sales relative to revenues, were up to 53% (9M/2010: 47%).

The Company's Q3/2011 gross profit decreased by 50% sequentially and 65% year on year due to the higher percentage of cost of sales relative to revenues and it amounted to EUR 38.7m (Q2/2011: EUR 76.9m; Q3/2010: EUR 110.6m) with a 43% gross margin (Q2/2011: 44%; Q3/2010: 52%).

The first nine months 2011 gross profit decreased by 25% year on year to EUR 219.7m (9M/2010: 294.5m), resulting in a nine months gross margin of 47% (9M/2010: 53%).

In an absolute sequential quarterly comparison, the Q3/2011 operating costs of EUR 38.0m (42% of total revenues) were 68% higher than in Q2/2011 with EUR 22.5m (13% of total revenues). Year on year, they were 36% higher than the EUR 28.0m (13% of total revenues) recorded in Q3/2010. This development is principally due to an increase in net other operating expenses, mainly reflecting the adverse effects of quarter-end mark-to-market of pending hedging instruments and customer deposits.

In a nine months comparison, operating costs decreased year on year in absolute terms by 14% to EUR 89.9m (9M/2010: EUR 104.9m). Relative to revenues they were stable at 19% with relatively high net other operating expenses in both periods.

The total operating costs were influenced by the single factors described hereafter:

In Q3/2011, selling expenses were stable at their absolute Q2 cost level of EUR 7.2m, while increasing relative to revenues, by 4 percentage points sequentially (Q3/2011: 8%; Q2/2011: 4%). Year on year, they were down by 51% from EUR 14.8m in Q3/2010. Relative to revenues they increased by one percentage point to 8% (Q3/2010: 7%), mainly due to lower sales volumes in Q3/2011.

In a nine months comparison, selling expenses decreased year on year by 37% to EUR 25.0m (9M/2010: EUR 39.9m), mainly due to the lower sales volumes, lower regional sales commissions and warranty expenses. Selling expenses relative to revenues decreased year on year by 2 percentage points to 5% compared to 7% in 9M/2010.

In Q3/2011, general and administrative expenses were down 16% compared to the previous quarter mainly due to lower external consultancy charges. Year on year, the general and administrative expenses were 4% lower amounting to EUR 7.4m or 8% of revenues (Q2/2011: EUR 8.7m, 5%; Q3/2010: EUR 7.7m, 4%).

In a nine months comparison, the 14% year on year increase in general and administration expenses to EUR 24.9m in 9M/2011 (9M/2010: EUR 21.8m) was principally due to increased personnel and IT infrastructure costs. General and administration expenses compared to revenues remained relatively stable at 5% of sales in 9M/2011 compared to 4% in 9M/2010.

Research and development costs in Q3/2011 also remained stable and at a similar level as in the previous quarter, amounting to EUR 11.8m or 13% of revenues, (Q2/2011: EUR 11.5m; Q3/2010: EUR 11.8m).

Nine months R&D costs increased by 7% year on year, from the EUR 33.5m recorded in 9M/2010 to EUR 35.8m in 9M/2011. This was due to the previously predicted increase in research and development activities requiring additional personnel and increased material consumption, depreciation and facilities' costs, including those for the new R&D center. In relative terms, R&D costs in 9M/2011 were slightly higher at 8% of revenues (9M/2010: 6%).

This strong commitment to R&D, despite the current market difficulties, reflects the ongoing importance of AIXTRON's research and development activities, resulting in a comprehensive pipeline of competitive products.

The previously predicted increase in the average number of R&D employees in 9M/2011 to 266 (9M/2010: 238), illustrates the degree to which AIXTRON is committed to and maintains a strong, well funded and focused R&D program within the business.

The new R&D center remains on budget and on schedule to be fully completed by the first quarter of 2012, although the first systems to be installed in this state-of-the-art facility will commence commissioning in Q4/2011.

Key R&D Information

Net other operating income and expenses in Q3/2011 resulted in expenses of EUR 11.7m, compared with an income of EUR 4.9m in Q2/2011 and an income of EUR 6.3m in the same period a year ago.

In the first nine month of 2011, the net other operating income and expenses resulted in an expense of EUR 4.2m compared to expenses of EUR 9.7m in 9M/2010.

Most of the Q3/2011 net other operating expenses are attributable to a currency related expense of EUR 12.4m (Q2/2011: EUR 4.6m income; Q3/2010: EUR 5.6m of income; 9M/2011: EUR 4.6m of expenses; 9M/2010: EUR 13.0m of expenses) principally from mark-to-market of USD/EUR hedging contracts and USD denominated advance payments from customers executed at quarter end. EUR 0.5m of R&D grants (Q2/2011: EUR 0.3m; Q3/2010: EUR 0.2m; 9M/2011: EUR 1.6m; 9M/2010: EUR 2.5m), received in Q3/2011, were recorded as other operating income.

Consequently, the Q3/2011 operating result came in slightly above break-even, at EUR 0.6m with a 1% EBIT margin (Q2/2011: EUR 54.3m or 31% margin; Q3/2010: EUR 82.6m or 39% margin). This Q3 decline in EBIT performance is principally due to the lower revenue volume, unchanged cost base and increased currency effects.

In a nine months comparison, the same influences apply and consequently the operating result decreased year on year by 32%, from EUR 189.6m in 9M/2010 to EUR 129.8m in 9M/2011 with a 6 percentage points lower EBIT margin of 28% (9M/2010: 34%).

The Q3/2011 result before taxes amounted to EUR 1.8m compared with EUR 54.3m in Q2/2011 and EUR 82.8m in Q3/2010. The Company recorded a net finance income in Q3/2011 of EUR 1.2m. The nine months result before taxes of EUR 131.3m in 9M/2011 compares to EUR 190.3m in 9M/2010, after a year on year decrease by 31%, with a net finance income of EUR 1.5m in 9M/2011 (9M/2010: EUR 0.7m).

AIXTRON recorded a tax expense of EUR 1.8m in Q3/2011 (Q2/2011: EUR 16.1m; Q3/2010: EUR 26.1m) mainly due to elimination effects on intercompany transactions. The nine months 2011 tax expense amounted to EUR 40.8m, at a stable effective tax rate of 31% of the profit before tax (9M/2010: EUR 59.4m or 31%).

The net income for Q3/2011 was down to EUR 0.03m (Q2/2011: EUR 38.2m or 22% of revenues; Q3/2010: EUR 56.8m or 27% of revenues). The nine months 2011 net income came in at EUR 90.5m (19% of revenues) and was 31% down year on year, from EUR 130.9m (23% of revenues) in 9M/2010.

Development of Orders

Equipment Orders

	9M/2011	9M/2010	9M-9M
	EUR million	EUR million	EUR million	%
Equipment order intake	484.1	544.3	–60.2	–11
Equipment order backlog (end of period)	244.8	278.7	–33.9	–12

Against the backdrop of the rapid investment adjustments being made by the Asian LED manufacturers in Q3, the equipment order intake recorded in Q3/2011 amounted to EUR 51.5m, which was 77% less than the EUR 222.2m in Q2/2011 and 74% lower in a year on year comparison (Q3/2010: EUR 200.4m). As a matter of internal policy, the 2011 order intake in US Dollars is recorded at the current 2011 budget exchange rate of 1.35 USD/EUR (2010: 1.50 USD/EUR).

The 9M/2011 equipment order intake decreased year on year by 11% and amounted to EUR 484.1m against the EUR 544.3m recorded in 9M/2010.

The decision to reduce the total equipment order backlog by EUR 100m in mid-September was taken after intense consideration of the rapidly changing market circumstances and as a result of the Management's desire to re-establish stable and prudent ground for the order backlog.

Consequently, the revised total equipment order backlog at the end of Q3/2011 stood at EUR 244.8m, which is EUR 128.7m or 34% less (EUR 28.7m or 10% less, net of the EUR100m adjustment implemented on September 15), than the EUR 373.5m recorded at the end of Q2/2011.

Compared with the opening backlog of EUR 302.3m as of January 1, 2011, the equipment order backlog decreased by EUR 57.5m or 19%. Year on year, the order backlog decreased by EUR 33.9m or 12% (EUR 278.7m as of September 30, 2010).

Order Recognition

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 all of the following minimum criteria:

• 1 The receipt of a firm written purchase order and
• 2 the receipt of the agreed deposit and
• 3 the accessibility of the required shipping documentation and
• 4 a customer confirmed agreement on a system specific delivery date.

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 additionally 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 that Management assessment concludes, that there is an unacceptable degree of risk of 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 points 1 – 4 above.

Interim Management Report // Financial Position and Net Assets

The Company recorded no bank borrowings as of September 30, 2011 and December 31, 2010.

The equity ratio increased to 76% as of September 30, 2011, compared to 73% as of December 31, 2010, principally due to higher retained earnings.

AIXTRON Group's capital expenditures of the first nine months of 2011 amounted to EUR 21.6m (9M/2010: EUR 19.1m), of which EUR 19.3m (9M/2010: EUR 18.1m) were related to property, plant and equipment (including testing and laboratory equipment).

Cash and cash equivalents (including cash deposits with a maturity of more than three months) decreased by EUR 66.1m or 17% to EUR 318.6m (EUR 190.7m + EUR 127.9m cash deposits) as of September 30, 2011 compared to EUR 384.7m (EUR 182.1m + EUR 202.6m cash deposits) as of December 31, 2010. This decrease was mainly due to lower advance payments from customers at currently low order levels, high work in progress and the dividend payment of EUR 60.7m in Q2/2011. Those effects were not fully offset by the cash inflow of the period.

The value of property, plant and equipment increased to EUR 89.9m as of September 30, 2011 (EUR 77.9m as of December 31, 2010), principally due to investments in R&D.

The decrease in the value of goodwill from EUR 62.2m as per December 31, 2010 to EUR 61.7m as per September 30, 2011 resulted purely from currency translation adjustments. There were no additions or impairments in the first nine months of 2011.

The value of other intangible assets decreased from EUR 7.0m as per December 31, 2010 to EUR 6.6m as per September 30, 2011. The recorded differences arose mainly from amortization.

Inventories, including raw materials, work in progress and finished goods, increased by 53% from EUR 167.2m as of December 31, 2010 to EUR 255.5m as of September 30, 2011, mainly due to customer delayed delivery plans.

In the nine months reporting period, retained advance payments from customers have decreased by EUR 24.2m, or 21%, from EUR 117.5m as of December 31, 2010 to EUR 93.3m as of September 30, 2011, and are 11% down sequentially from the end of Q2/2011 (EUR 104.6m). This is mainly due to lower advance payments from customers at currently low order levels.

Trade receivables decreased from EUR 88.4m as of December 31, 2010 to EUR 34.9m as of September 30, 2011, as a result of reduced shipments in the third quarter.

Interim Management Report // Opportunities and Risks

AIXTRON believes that the following market trends and opportunities of the relevant end user markets could have a positive effect on future business:

Short Term

// Increasing adoption of LEDs for exterior, public street and commercial lighting. // Increased adoption of LEDs for consumer and residential general lighting applications.

Mid Term

• // Increased emergence of high volume Silicon Carbide (SiC) production applications and emerging hybrid automotive and photovoltaic transistor applications.
• // Increased emergence and further development of plastic electronics flexible organic TFT backplanes.
• // Development of next generation NAND, DRAM and PRAM memory devices.

• // Development of UV LED applications e.g. for water purification.
• // Development of GaN on Silicon based devices for energy efficient power electronics.

AIXTRON is exposed to a series of risks which are described in detail in the "Risk Report" of the Annual Report 2010 and in the section "Risk Factors" in AIXTRON's 2010 20-F Report, which has been filed with the U.S. Securities and Exchange Commission on March 1, 2011. Copies of the Company's most recent Annual Report and Form 20-F are available on the Company's website at www.aixtron.com (sections "Investors/Reports" and "Investors/US-Listing"), as well as on the SEC's website at www.sec.gov.

During the first nine months of 2011, AIXTRON Management was not aware of any significant additions or changes in the risks as described in the 2010 Annual Report/20-F Report referred to above.

Interim Management Report // Outlook

On September 15, 2011, the Company issued a public notification of our decision to adjust our full-year guidance to reflect the current market environment arising from the deteriorating macroeconomic conditions in the third quarter 2011 and the consequently more cautious investment activities, especially by Asian customers.

In 2011, we expect to generate revenues of EUR 600m – 650m and an EBIT margin of circa 25 – 30%. This guidance reflects our opinion on conversion risk, purchase order delays and deferred system delivery requests into 2012 by several customers. We are not expecting any further significant investments into backlighting capacity but we do expect to see increasing equipment investments for LEDs in general lighting applications. Additionally, we no longer expect that subsidized regional demand from within Asia for our systems will necessarily bridge the short term gap between the end of the backlighting investment cycle and the expected acceleration of the emerging LED general lighting investment cycle.

However, the very positive customer response to the Company's recent new MOCVD CRIUS® II-L product release encourages the AIXTRON Management conviction that the imminence of an emerging LED lighting industry in conjunction with initiatives such as the Chinese 5 year plan and the Korean 60/20 initiative continues to support the positive outlook for the LED industry and AIXTRON's contribution to that growth.

Although the precise timing of significant LED general lighting investment remains unclear, there are already some encouraging signs supported by government initiatives and positive product pricing developments.

Any acceleration of investments into LED lighting applications will positively influence AIXTRON's business outlook and consequently, we believe that our LED production equipment will remain the most prominent element of our future revenues.

In the meantime, we will continue to leverage our operational flexibility to cut costs and adjust our operations in line with our revised sales projections. Our objective remains to draw on this flexibility to protect our ability to make efficient use of our cash in order to maintain our strong balance sheet position.

We will also continue to closely watch the volatile USD/EUR exchange rate development and the potential consequential effects on the Company's revenues and profitability and will, where possible, economically and expediently, employ appropriate financial instruments to mitigate potential risk.

During the remaining three months of the year, we plan to continue to invest into R&D laboratory equipment, into the expansion of our activities in China and into the completion of our new R&D center building in Herzogenrath, Germany.

AIXTRON carries no debt and we continue to believe that our Company has sufficient funds and instruments in place to ensure that the foreseeable needs of the business can be met.

As at September 30, 2011, we had no binding agreements for participation financing, company acquisitions or transfers of parts of the Company.
