2. Important Factors of the Reporting Period

TV backlighting continues to drive order intake: new all time high

_ Equipment order intake in Q3/2009 reached EUR 117.6m, and consequently was 103% higher than in Q2 and 125% higher year-on-year. As the demand for LED applications, and TV backlighting in particular, bring the AIXTRON order volume to a new all time high, market sentiment and faster than predicted adoption suggest that this trend will continue into 2010.
_ Benefitting from the increasing business volume, Q3/2009 gross margin, EBIT margin, and net profit margin (42%, 20%, and 14% respectively) rose sequentially and on a year-on-year comparison basis.

Strategies Unlimited increases market estimates again

_ Within its latest August 2009 report, Strategies Unlimited (an independent semiconductor market research institute) again increased its High Brightness ("HB") LED growth estimates for the period until the year 2013, especially for applications such as LED backlighting and general illumination. At the beginning of the year, in February, the institute had published lower figures for this same period, influenced by the market mood at that time arising from the financial and economic crisis.
_ However, aided by the increased applications and substantial competitive capacity increase, the cost of LEDs is predicted to continue to drop while their performance continues to improve.
_ Under these conditions, the market for HB LEDs in illumination is, according to Strategies Unlimited, now forecast to reach nearly USD 2.85bn by 2013, corresponding to a CAGR (2008 through 2013) of 40%. This market development is earlier than previously predicted.
_ Other applications with the potential for a larger than recently published market growth over the next five years, include backlighting of notebook computer displays, LCD TVs, and monitors. By 2013, the market for HB LEDs in signs and displays is estimated by Strategies Unlimited to reach USD 7.2bn, which corresponds to a CAGR of 55%.

US-Dollar drifting lower against the Euro

_ After the period of strength for the US-Dollar against the Euro seen at the beginning of the year, the US-currency drifted lower against the Euro starting in March, eventually breaching the USD 1.40 level by end of May.
_ The weakening US-Dollar-trend continued in Q3/2009. A period of strengthening stock market data and positive economic news was coincidental with the falling value of the dollar taking it to a year-low against the Euro at USD 1.48 by September 22nd. At quarter-end, the Euro bought 1.46 USD.
_ Nevertheless, the average US-Dollar/Euro exchange rate of Q3/2009 was USD 1.42, 6% stronger than the USD 1.50 average of Q3/2008. This has in turn positively influenced AIXTRON's Q3/2009 comparable revenues, gross margin and EBIT, as more than 70% of AIXTRON revenues are generally transacted in US-Dollars, with only roughly 20% of the Company's cost being in US-Dollars.
_ The UK-Pound also began to suffer against other currencies during the period, notably the US-Dollar and the Euro, driven by the market expectation of an extended period of low interest rates in the UK.
_ AIXTRON routinely employs a variety of hedging instruments to mitigate the effects of currency movements.

Market capitalization exceeds EUR 1 billion mark

_ In mid July 2009, the AIXTRON market capitalization rose above the EUR 1 billion mark. With 91,357,552 ordinary non-par value AIXTRON-shares outstanding at that time (consisting of 90.894.616 shares already registered with the commercial register and additional 462.936 issued under stock option programs but not yet registered with the commercial register), at a share price of EUR 10.95, the AIXTRON market capitalization became just over EUR 1 billion for the first time since June 2002.
_ On August 25, the AIXTRON-share was added to the components of the Dow Jones STOXX® 600 Index with a 0.0304% weighting. The 600 index stocks are ranked by free float market capitalization and represent large, mid and small capitalization companies across 18 countries of the European region.
_ By mid September 2009, the AIXTRON market capitalization rose further to exceed EUR 1.5 billion. At quarter-end, on September 30, 2009, the market capitalization had reached EUR 1.7bn with a closing share price of EUR 18.62.
_ This considerable increase in market capitalization was coincidental with an increasing number of large institutional AIXTRON investors. A minimum market capitalisation value is often set as a minimum threshold for large institutional investors to consider an investment. This AIXTRON-shareholder mix change is seen by Management a positive development in the company's shareholder base.

Fidelity becomes largest single shareholder group

_ On September 3, 2009, Fidelity Management & Research Company, Boston, MA, USA, informed the Company according to Article 21, Section 1 of the WpHG, that via shares its voting rights on AIXTRON AG had exceeded the 10% limit on August 26, 2009. On that day, the Fidelity group, through subsidiary investments, held 10.14% (this corresponds to 9,264,482 voting rights) of the AIXTRON share capital.
_ The US-headquartered Fidelity group is one of the biggest investment companies in the world and provides a large family of mutual funds all over the globe.

Final Acceptance of first 300mm Cluster Tool by Philipps-University of Marburg

_ The final acceptance documentation for the newly developed AIXTRON CRIUS® CCS®

MOVPE system with 300mm wafer configuration, delivered in Q1/2009 and then successfully installed and commissioned, has been signed off by Philipps-University of Marburg at the end of Q3/2009. Consequently, the total revenue of this previously unproven technology was recorded within Q3/2009 as silicon revenue.

_ The cluster tool includes two silicon- and III/V-based material modules and is therefore suitable for the growth of III/V semiconductor structures on commercially available silicon wafers, with the aim of monolithically integrating optoelectronics with siliconbased microelectronics.
_ The successful system acceptance provides further evidence for the emerging convergence of conventional silicon technology with compound semiconductor technology. In Management's opinion, AIXTRON's market leading core competence with compound material technology can also be effectively employed as a complex solution technology for silicon customers. Potential future applications are perceived to be in next-generation data communication devices and highly efficient silicon solar cells.

New Research Project: Semiconductor-Nanowires for Solar Cells and LEDs (NaSoL)

_ During Q3/2009, the NaSoL research project, supported by the state of Northrhine-Westfalia (in the scope of their technology and innovation program TIP) was formally approved and started.
_ Under the project leadership of AIXTRON, and in cooperation with the University of Duisburg-Essen and other industrial partners, the research project team will design and build a technology platform for LEDs and solar cells employing nanowire-structures.
_ The project's goal is to develop new growth processes for nanowires, replacing traditional semiconductor layers, using metal organic gasphase epitaxy. The plan is to increase the efficiency both of solar cells and of white LEDs.

Award for AIXTRON founder Dr. Jürgensen during Semicon Europa

_ In Q3/2009, AIXTRON was informed that its founder and current Deputy Chairman of the AIXTRON Supervisory Board Dr. Holger Jürgensen had been selected as winner of the European SEMI Award 2009. The award was presented to him during Semicon Europa 2009, in Dresden, Germany on October 6.
_ In 1983, Dr. Jürgensen, together with two colleagues had originally founded AIXTRON, with the initial objective of developing and, ultimately, commercializing, MOCVD deposition technology. With his engineering vision and commercial drive he has played a major role in bringing MOCVD deposition equipment from the very early days of small R&D systems to today's mass production scale equipment.
_ Dr. Jürgensen has not only played a pivotal role in the creation of the MOCVD industry, but he also laid the essential technical foundations for AIXTRON's subsequent diversification into adjacent technologies, including OLED and Carbon Nanotube material deposition and provided a clear roadmap path to the impending convergence of Compound and Silicon technologies.

3. Results of Operations

3.1. Development of Revenues

During the first nine months of 2009, AIXTRON recorded revenues of EUR 184.9m, a EUR 7.2m or 4% reduction compared to EUR 192.1m in the same nine months period last year.

The positive average US-Dollar/Euro rate (9M/2009: USD1.36 versus 9M/2008 USD1.52; +12%), and the progressively strong revenue volumes within the first nine months of the year, contributed to the near attainment of last year's strong revenue number.

The EUR -7.2m difference in revenues year-on-year was largely driven by lower service and spare parts revenues (EUR -3.5m), primarily due to the under-utilization of customers' equipment in the beginning of the year. This market condition was strongly influenced by customer's inventory reduction programs brought about by fears of recession at that time. Consequently, service and spare parts revenues only generated 9% of total 9M/2009 revenues (9M/2008: 11%).

Nine monthly sales of compound semiconductor deposition equipment (of EUR 158.2m) were 2% less in comparison to the same period last year. This strong comparative performance in 2009 was largely possible, despite the recession, because of the significant Q2 and Q3 quarterly revenue volumes, which predominantly stem from customers' increased purchasing of systems for the production of LEDs.

The proportion of revenues from silicon semiconductor deposition equipment to total revenues remained the same at 5%. Included in the nine-monthly figure of 2009 (EUR 9.3m) is the total revenue (EUR 4.1m) of a newly developed 300m cluster tool for Philipps-University of Marburg.

Revenues by Technology	9M/2009		9M/2008		+/–
	m EUR	%	m EUR	%	m EUR	%
Revenues	184.9	100	192.1	100	-7.2	-4

of which other revenues (service, spare parts, etc.)	17.4	9	21.0	11	-3.6	-17

80% of total revenues in 9M/2009 were delivered to customers in Asia. The comparatively high European revenue share (15% in 9M/2009 versus 6% in 9M/2008) was significantly influenced by the Plastic Logic system revenue recorded in Q1/2009. The remaining revenue, with an almost unchanged 5% share, was generated in the USA.

Revenues by Region	9M/2009		9M/2008		+/–
	m EUR	%	m EUR	%	m EUR	%

3.2. Development of Results

Cost Structure	9M/2009		9M/2008		+/–
	m EUR	% Revenues	m EUR	% Revenues	m EUR	%
Cost of Sales	105.7	57	114.8	60	-9.1	-8
Gross profit	79.2	43	77.3	40	1.9	2
Operating Costs	50.2	27	52.2	27	-2.0	-4

Research and development costs	24.9	13	20.7	11	4.2	20
Net other operating (income) and expenses	7.1	-4	3.2	-2	3.9	122

Cost of sales improved from 60% of revenues in 9M/2008 to 57% of revenues in the current reporting period. In absolute terms, cost of sales reduced by 8% from EUR 114.8m in 9M/2008 to EUR 105.7m in 9M/2009.

At the same time, the gross margin improved by 3 percentage points from 40% of revenues to 43% of revenues, while the gross profit increased in absolute terms by 2% to EUR 79.2m in 9M/2009 (9M/2008: EUR 77.3m). This improvement resulted from a more favorable revenue mix with a higher percentage of final acceptances especially in the first quarter of 2009 and a favorable USD/EUR exchange rate.

Compared to the first nine months of 2008, operating costs in 9M/2009 decreased by 4% to EUR 50.2m in absolute terms. Operating costs relative to revenues remained stable at 27%, and were influenced by the following factors:

Selling expenses relative to revenues, improved to only 9% of revenues in the first nine months of 2009 (9M/2008: 11%). In absolute terms, the selling expenses were substantially lower (by 20%) at EUR 16.3m year-on-year (9M/2008: EUR 20.5m). This improvement in relative and absolute terms was mainly due to a different geographical mix of sales and therefore lower variable sales commissions, and controlled discretionary expenses.

General and administration expenses increased to EUR 16.1m or 9% of revenues in 9M/2009 (9M/2008: EUR 14.2m or 7% of revenues) principally due to provisions for profit-related variable administration expenses.

Compared to the same period last year, Research and development spending increased by EUR 4.2m or 20% in 9M/2009 to EUR 24.9m (9M/2008: EUR 20.7m), the largest single element being the expense for one publicly funded R&D project of EUR 1.6m in Q1/2009. Relative to revenues, R&D spending increased by 2 percentage points from 11% to 13%.

The continued focus on R&D across the Group is driven by Management's determination to remain a major player in markets judged by many to hold significant growth opportunities for many years to come.

Key R&D Information	9M/2009	9M/2008	+/–
R&D expenses (million EUR)	24.9	20.7	20%
R&D expenses, % of sales	13%	11%	2 pp
R&D employees (period average)	205	213	-4%
R&D employees, % of total headcount (period average)	33%	34%	-1 pp

Net other operating income and expenses more than doubled by EUR 3.9m, resulting in an operating income of EUR 7.1m in the first nine months of 2009 (9M/2008: EUR 3.2m of income).

Included in the other operating income of 9M/2009 are the gains made from the sale of the Aachen office building (EUR 1.3m) and a compensation payment for a single cancelled order (EUR 2.5m), both booked in Q1/2009. Also accounted for in the 9M/2009 other operating income, are higher R&D grants of EUR 0.8m. A decrease of bad debt provisions by EUR 1.3m also positively influenced the net other operating income and expenses.

Negative foreign exchange effects, arising principally from USD/EUR currency transactions and translations and from hedging contract premiums, resulted in a net expense of EUR 1.4m in 9M/2009 versus a net income of EUR 1.3m in the previous year.

Operating income (EBIT) in 9M/2009 was EUR 29.0m with a 16% margin, 16% and 3 percentage points higher year-on-year (9M/2008: EUR 25.0m; 13% margin), principally due to a good revenue mix, a still favorable USD/EUR exchange rate, and higher other operating income items.

Result before taxes increased by 7% from EUR 27.6m in 9M/2008 to EUR 29.6m in 9M/2009, despite lower interest income.

AIXTRON recorded a tax expense of EUR 9.2m of the profit before tax in the first nine months of 2009, with an effective tax rate of 31% (based on the expected tax rate for the full financial year 2009), similar to 9M/2008 (EUR 8.7m or 32% of the profit before taxes).

The 9M/2009 net income was EUR 20.4m, 8% up year-on-year from EUR 18.9m in 9M/2008.

3.3. Development of Orders

AIXTRON's total nine months 2009 equipment order intake was 2% lower than last year's high level of EUR 210.2m, coming in at EUR 206.7m.

Nevertheless, the 9M/2009 order volume reflects a progressively rising order trend, whereas in 2008, the nine month total was reached on a sequentially declining quarterly order intake trend. The Q3/2009 order intake figure (EUR 117.6m; an increase of 103% sequentially, and 125% year-on-year) represents the highest quarterly order volume in AIXTRON's history.

EUR 206.1m or 99.7% of the total value of 9M/2009 equipment orders (EUR 198.4m or 94.4% of total order intake in 9M/2008) came from compound semiconductor equipment customers, who are predominantly focused on the production of high brightness LEDs and the corresponding end-market applications. Consequently, the absolute order intake for compound semiconductor equipment increased by 4% in a year-on-year nine-monthly comparison.

This positive development for compound semiconductor equipment marks the beginning of a new LED investment cycle, which started after the low point of demand in Q1/2009, and is primarily driven by the increased adoption of LED TV applications. The previous LED investment cycle with its equipment demand peak in Q4/2007 had been primarily driven by notebook backlighting.

The proportion of orders received in the first nine months of 2009 for silicon semiconductor equipment dropped to 0.3% of total equipment order intake, from 5.6% in 9M/2008. In absolute numbers, the order intake for silicon semiconductor equipment decreased to EUR 0.6m in 9M/2009 from EUR 11.8m in 9M/2008, due to the persistently negative memory market environment. Management believes that there is little evidence to suggest that this situation will improve during the last quarter of this year.

Separately; the development work being conducted on next-generation memory and logic equipment continues, with customer demonstrations and film development work being done within the Company's research labs and at customers' facilities. This work, combined with the involvement of Sunnyvale staff in next generation compound and other group nano-technology projects, means that the team in Sunnyvale continue to make a positive and valuable contribution to the Group's objectives.

The equipment order backlog of EUR 152.4m at September 30, 2009 is 4% lower than at the same point in time in 2008 (EUR 158.1m). However, with the increasing 2009 order intake volumes, the September 30 order backlog has further increased (by 39%) versus the June 30 figure of EUR109.4m. The Management expects that about EUR 88m of the 9M/2009 period end backlog will be converted into revenues before the end of the year 2009.

The order backlog for compound semiconductor equipment was EUR 149.1m as of September 30, 2009 (98% of total backlog), representing a 1% decrease year-on-year.

The remaining backlog figure of EUR 3.3m (2% of total backlog) is made up of silicon semiconductor equipment orders.

As a matter of internal policy, AIXTRON records only equipment orders as actual order intake and order backlog, if the Company has received a firm purchase order, an agreed deposit and a customer-confirmed delivery date.

4. Financial Position and Net Assets

The Company recorded no bank borrowings as of September 30, 2009 and December 31, 2008.

The equity ratio decreased to 65% as of September 30, 2009, from 68% as of December 31, 2008, principally due to a higher balance sheet total because of the increasing business volume (higher cash and cash deposits on the asset side; more advanced payments, trade payables and tax liabilities on the liabilities side).

The AIXTRON Group's capital expenditures of the first nine months of 2009 amounted to EUR 6.8m, the large majority of which was related to purchases of technical equipment (including testing and laboratory equipment). In 2008, the nine months capital expenditures were 36% higher (at EUR 9.2m) because of investments at that time into the new headquarters in Herzogenrath.

The value of property, plant and equipment decreased to EUR 32.8m as per September 30, 2009 (EUR 39.3m as of December 31, 2008), principally due to the sale of the Aachen office building.

The slight decrease in recorded goodwill from EUR 58.7m as per December 31, 2008 to EUR 57.1m as per September 30, 2009 resulted purely from currency translation. There were no additions or impairments in the first nine months of 2009.

The value of other intangible assets decreased from EUR 10.3m as per December 31, 2008 to EUR 7.8m as per September 30, 2009 principally due to depreciation.

Cash and cash equivalents including cash deposits increased by 58% to EUR 111.1m (EUR 75.1m+ EUR 36.0m) as of September 30, 2009 compared to EUR 70.5m (EUR 67.5m + EUR 3.0m) as of December 31, 2008. The 9M/2009 period end cash position includes, amongst other factors, the accounting for EUR 6.7m proceeds from the sale of the Aachen office building in Q1, EUR 2.6m for stock option exercises, the payment of an EUR 8.2m shareholders' dividend in Q2, comparably higher working capital and lower capital expenditures, additional EUR 33.0m of bank deposits, and EUR 20.4m of 9M/2009 cumulated net profit.

Trade receivables increased from EUR 38.8m as of December 31, 2008 to EUR 44.4m as of September 30, 2009 in line with the increased business volume.

AIXTRON is exposed to a series of risks which are described in detail in chapter 7. "Risk Report" of the Annual Report 2008 and in the section "Risk Factors" in AIXTRON's 2008 20-F-Report, which has been filed with the U.S. Securities and Exchange Commission on March 12, 2009. Copies of the Company's most recent Annual Report and Form 20-F are available on the Company's website at http://www.aixtron.com (sections "Investors/Reports" and "Investors/US-Listing"), as well as on the SEC's website at http://www.sec.gov.

On April 7, 2009, the district court in Aachen judged in AIXTRON's favor in the German action for a negative declaratory judgment against International Rectifier Corporation ("I.R."), and the German counterclaim of I.R. was dismissed. This judgement is final.

In February 2009, the United States District Court in California dismissed I.R.'s federal claims against AIXTRON. I.R. subsequently dropped its federal claims and re-filed its California state law claims in the California Superior Court for Los Angeles County. I.R. has since dropped two of its California state law claims against Aixtron, and is continuing to assert three of its claims. AIXTRON continues to reject all allegations involved and continues to defend itself against the allegations and claims raised in the action.

During the first nine months of 2009, AIXTRON Management was not aware of any further significant additions or changes in the risks as described in the 2008 Annual Report/20-F-Report referred to above.

6. Outlook

With a steadily and strongly increasing order activity after the trough in Q1/2009 (+85% from Q1 to Q2, +103% from Q2 to Q3), in line with our previous predictions, we remain positive with respect to the continuation of this increasing LED investment cycle, which is primarily driven by the adoption of LED TV applications.

We also remain confident in our business model and are therefore optimistic about the increasingly evident medium to long-term trends towards the growing penetration of LED technologies in a wide range of applications and the consequent positive effect on future order intake.

We enter the last quarter of the year with a full order book (backlog as per September 30: EUR 152.4m), which has been fuelled by an increasing momentum of LED technology demand, a rapid return to very high customer production utilization rates, and improved visibility of LED manufacturers' demand requirements. The Management expects that about EUR 88m of the 9M period end backlog will be converted into revenues before the end of the year 2009.

This enables us to further increase our revenue guidance for fiscal year 2009 to EUR 280m. We also believe that, due to higher business volume, AIXTRON can deliver a higher 2009 EBIT margin of 18%.

The Management will continue to closely watch the USD/EUR exchange rate and the potential effects on the company's revenues and profitability.

During the last three months of the year, the Company plans to continue to invest in laboratory equipment and to continue the roll out of the group-wide SAP Enterprise Software System.

The Company continually reviews the availability of funds to ensure that the company has sufficient liquidity to meet the changing needs of the business. In Management's opinion, the Company currently has sufficient funds or instruments in place to ensure that the foreseeable needs of the business can be met.

As at September 30, 2009, AIXTRON had no binding agreements for participation financing, company acquisition or transfers of parts of the Company.
