Interim Management Report

1. Business Activity

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

The Company markets and sells its products worldwide, principally through its own direct sales organization, but also through appointed dealers and sales representatives.

AIXTRON's business activities include developing, producing and installing equipment for the deposition of semiconductor materials, process engineering, consulting and training, including ongoing customer support and after-sales service.

AIXTRON supplies its customers with both production-scale material deposition systems and small scale systems for Research & Development ("R&D") or small scale production.

Demand for AIXTRON's products is driven by increased processing speed, improved efficiency, and reduced cost of ownership requirements for current and emerging microelectronic and optoelectronic components. The ability of AIXTRON's products to precisely deposit thin material films and the ability to control critical surface dimensions in these components, enables manufacturers to improve performance, yield and quality in the fabrication process of advanced microelectronic and optoelectronic devices.

AIXTRON's product range includes customer-specific systems capable of depositing material films on a diverse range of different substrate sizes and materials.

The deposition process technologies include Metal-Organic Chemical Vapor Deposition ("MOCVD") for the deposition of compound materials as for the production of LEDs, Power Electronics or processors as well as thin film deposition of organic materials. These include Polymer Vapor Phase Deposition ("PVPD™"), Organic Vapor Phase Deposition ("OVPD®") especially for large area deposition for Organic Light Emitting Diodes ("OLED") applications. Plasma Enhanced Chemical Vapor Phase Deposition ("PECVD") is being employed for the deposition of complex Carbon Nanostructures (Carbon Nanotubes, Nanowires or Graphene).

For silicon semiconductor applications, AIXTRON systems are capable of depositing material films on wafers of up to 300mm in diameter, by employing technologies such as: Chemical Vapor Deposition ("CVD") and Atomic Layer Deposition ("ALD").

The Company's R&D capability remains of important strategic significance, as it provides for a competitive, state-of-the-art technology portfolio and supports the future business development. Therefore, AIXTRON is committed to investing specifically in research and development projects to not only further pursue the Company's leading technology position in MOCVD equipment but also to penetrate growth markets in the fields of Power Electronics, Organic Semiconductors and next generation Memory and Logic applications.

Environmental protection and the responsible use of resources are an essential part of AIXTRON's business strategy. The Company's engineers work on improving AIXTRON's systems continuously, both in terms of resource conservation and environmental-friendly design and function. The implementation of an energy management system implemented on Company level according to DIN EN ISO 50001:2011 contributes to the efficient use of energy and the careful use of resources.

2. Macroeconomic and Industry Developments

Macroeconomic developments

The positive growth effects in the advanced economies, most notably the U.S., are opposed by a slackening dynamic of some important emerging and developing countries, such as China. This is also reflected in the International Monetary Fund's (IMF) forecast (published in the World Economic Outlook on April 14, 2015) for the year 2015 which sees a slight increase of global growth to 3.5% (2014: 3.4%). While growth in the advanced economies is projected to accelerate from 1.8% to 2.4% the emerging and developing countries are expected to experience a slight decrease from 4.6% to 4.3%. At the same time, a number of notable downside risks to the global economic development, such as the crises in the Ukraine and the Middle East, increased threat of terrorism, worries about deflationary tendencies in the euro area or the Greek debt crisis, still prevail.

However, in total AIXTRON does currently not expect the global economic environment to negatively affect its business development in 2015.

Driven by the positive economic development in the U.S. and the expansive monetary policy of the European Central Bank, reflected in the launch of a EUR 1 trillion bond buying program in March 2015, the US dollar exchange rate has seen a further significant improvement in the first quarter of 2015, reaching its peak at approximately 1.05 USD/EUR in mid-March. Compared to the previous year's closing price of 1.217 USD/EUR, the US dollar exchange rate at the end of the first quarter improved to 1.085 USD/EUR. Compared to the first quarter 2014 (closing price: 1.381 USD/EUR) the US dollar strengthened by approximately 21%. The average exchange rate used by AIXTRON to translate income and expenses denominated in US dollars in the first three months of 2015 was 1.16 USD/EUR (Q1/2014: 1.37 USD/EUR; Q4/2014: 1.25 USD/EUR). Thus, compared to the previous year, the US dollar was up about 18%, having a respectively positive effect on AIXTRON's US dollar denominated revenue and earnings in the first quarter 2015.

Industry developments

LED lighting is on the rise – lighting product manufacturers have announced strong growth of their LED businesses, in spite of continuously declining prices, and the independent market research firm Strategies Unlimited forecasts an average annual growth rate for LED luminaires of 11% from 2014 through 2022, with sales volume climbing from some USD 20 billion to more than USD 45 billion.

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 for 2015 to be valued at USD 628 million (2016e: USD 620 million) (Gartner Dataquest, Forecast: Semiconductor Manufacturing Equipment, Worldwide, 1Q15 Update, April 2015).

3. Business Performance and Key Developments

Demand for LED chips is growing due to an increasing penetration of LED technology in the lighting market and strong demand of LEDs for displays, leading to higher utilization rates of LED producers with orders and shipments in the first quarter remaining slow due to the cautious investment behavior of customers to purchase AIXTRON equipment.

Thus, at EUR 48.9m AIXTRON's total order intake (including spares & service) in the first quarter 2015 remained stable year-on-year and sequentially (Q1/2014 incl. spares & service: EUR 49.5m; Q4/2014 incl. spares & service: EUR 49.3m).

Revenues at EUR 40.3m in Q1/2015 were lower compared to the previous year and compared to the previous quarter (Q1/2014: EUR 43.9m; Q4/2014: EUR 58.0m).

First quarter cost of sales* at EUR 31.5m (Q1/2014: EUR 34.0m; Q4/2014: EUR 47.6m) were in line with revenue development and therefore lower year-on-year and compared to the previous quarter.

Q1/2015 gross margin* was 22% (Q1/2014: 23%; Q4/2014: 18%). Mainly due to lower revenues, the Q1/2015 gross profit* amounted to EUR 8.8m (Q1/2014: EUR 10.0m; Q4/2014: EUR 10.4m).

In the first quarter of 2015, AIXTRON continued with its reorganization efforts and initiated a reduction of approximately 60 of the 800 jobs across the group. Additionally, organizational structures have been changed in line with customer and market requirements. Alongside cost-cutting measures, AIXTRON is continuously pursuing new market opportunities, as evidenced by the acquisition of the OLED encapsulation specialist PlasmaSi, Inc. which was announced on April 8th, 2015. AIXTRON will continue to pursue opportunities in promising future business fields such as power and logic semiconductors as well as OLED. Those areas are strengthened through the reorganization of the company.

The operating costs* at EUR 17.6m were lower sequentially and year-on-year, which was mainly due to lower research and development costs as well as a positive currency impact on other operating income (Q1/2014: EUR 20.9m; Q4/2014: EUR 29.3m).

At EUR -6.4m EBITDA in the first quarter 2015 was still negative but improved both against the previous year and sequentially (Q1/2014: EUR -7.1m; Q4/2014: EUR -13.9m).

As a result of the above mentioned development, Q1/2015 EBIT at EUR -8.8m improved both against the previous year and the previous quarter (Q1/2014: EUR -10.9m; Q4/2014: EUR -18.9m).

The net result for Q1/2015 amounted to EUR -9.5m (Q1/2014: -11.8m; Q4/2014: EUR -19.1m).

The operating cash flow in Q1/2015 amounted to EUR -8.6m (Q1/2014: EUR -9.8m; Q4/2014: EUR 9.8m), mainly reflecting the operating loss for the quarter. The free cash flow was EUR -12.1m (Q1/2014: EUR -13.8m; Q4/2014: 5.9m). Both cash flow figures exclude a cash flow effect of EUR -1.5m resulting from a short term loan prior to the acquisition of PlasmaSi, Inc.

AIXTRON reported cash and cash equivalents (including bank deposits with a maturity of more than three months) of EUR 263.2m as of March 31, 2015 which is EUR 4.9m below the EUR 268.1m recorded on December 31, 2014. The difference to the free cash flow stems mainly from currency effects of cash held in US-Dollars. The Company continues to record no bank borrowings.

4. Results of Operations

4.1. Development of Revenues

During the first three months of 2015, AIXTRON recorded total revenues of EUR 40.3m, a decrease of EUR 3.6m, or 8%, compared to the same period last year (Q1/2014: EUR 43.9m) reflecting the cautious investment behavior of customers for semiconductor deposition equipment from AIXTRON. Compared to the previous quarter, revenues in Q1/2015 decreased by 31% from EUR 58.0m in Q4/2014.

Equipment revenues in Q1/2015 were EUR 29.1m (Q1/2014: EUR 32.1m; Q4/2014: EUR 48.6m), representing 72% of the total Q1/2015 revenues (Q1/2014: 73%; Q4/2014: 84%).

The deposition equipment and upgrades bought by AIXTRON's customers in the first three months 2015 are predominantly used for the production of LEDs, which in turn are primarily employed as backlighting devices for LCD displays and general lighting applications. The next biggest end-market in terms of revenues for AIXTRON equipment in the first three months of 2015 was equipment for the silicon industry.

The remaining revenues were generated by the sale of spares and service and represented 28% of total revenues in Q1/2015 (Q1/2014: 27%; Q4/2014: 16%).

Revenues by Equipment, Spares & Service	2015 Q1		2014 Q1		+/-

Cost of sales* in Q1/2014 decreased by 7% year-on-year from EUR 34.0m in Q1/2014 to EUR 31.5m (78% of revenues). Sequentially, cost of sales were down 34% from EUR 47.6m (82% of revenues) in Q4/2014, both mainly due to the reduced sales volume.

Also mainly due to lower revenues, the Company's gross profit* in Q1/2015 decreased year-on-year to EUR 8.8m (Q1/2014: EUR 10.0m; Q4/2014: EUR 10.4m), resulting in a gross margin* of 22% (Q1/2014: 23%; Q4/2014: 18%).

Operating costs* in Q1/2015 of EUR 17.6m were reduced by 16% year-on-year compared to EUR 20.9m in Q1/2014, mainly due to lower research and development costs as well as positive currency effects. In a quarterly sequential comparison, operating costs were reduced by 40% from the EUR 29.3m recorded in Q4/2014 also due to the above mentioned reasons and due to restructuring costs that were included in Q4/2014.

The operating cost development was influenced by the following single factors:

Including higher sales commissions, selling expenses* in Q1/2015 increased by 6% year-on-year to EUR 3.3m. In line with revenues, selling expenses decreased sequentially (Q1/2014: 3.1m; Q4/2014: EUR 4.0m). In Q1/2015, selling expenses relative to revenues at 8% remained largely stable year-on-year and sequentially (Q1/2014: 7%; Q4/2014: 7%).

In Q1/2015, general and administration expenses were reduced both year-on-year (-16%) and sequentially (-21%) to EUR 4.3m (Q1/2014: EUR 5.1m; Q4/2014: EUR 5.4m).

Research and development costs in Q1/2015 decreased by 6% year-on-year and by 39% sequentially to EUR 12.9m (Q1/2014: EUR 13.7m; Q4/2014: EUR 21.2m), the sequential reduction mainly reflecting higher project related costs and restructuring costs which were included in the Q4/2014 figure.

One example within our R&D activities is the new OLED research project "FLEXOLIGHTING", which has been approved by the European Commission at the end of 2014 and was formally started in early 2015. The aim of the program is to produce large area OLED devices with improved cost efficiency, high brightness, high uniformity and long lifetime, and thus bridging the gap between research prototypes and low cost mass production technologies. The three year project, headed by Brunel University, involves various suppliers with AIXT-RON as production equipment supplier, with the ultimate goal of establishing unique technology know-how in Europe covering the whole supply chain.

Net other operating income and expenses in the first three months of 2015 resulted in an income of EUR 3.0m (Q1/2014: EUR 1.1m income; Q4/2014: EUR 1.3m income), mainly due to currency related gains.

In Q1/2015, AIXTRON recorded a net currency income of EUR 2.7m (Q1/2014: income of EUR 0.6m; Q4/2014: income of EUR 0.7m) from foreign currency transactions and translation differences.

EUR 0.2m of R&D grants, received in Q1/2015 (Q1/2014: EUR 0.4m; Q4/2014: EUR 0.7m), were recorded as 'other operating income'.

At EUR -6.4m EBITDA in the first quarter 2015 was still negative but improved both against the previous year and sequentially (Q1/2014: EUR -7.1m; Q4/2014: EUR -13.9m).

The absolute operating result (EBIT) improved in a year-on-year comparison by EUR 2.1m from EUR -10.9m in Q1/2014 to EUR -8.8m in Q1/2015 (Q4/2014: EUR -18.9m).

Result before taxes improved year-on-year by EUR 2.2m from EUR -10.7m in Q1/2014 to EUR -8.5m in Q1/2015 (Q4/2014: EUR -18.7m), including a net finance income of EUR 0.2m in Q1/2015 (Q1/2014: EUR 0.2m; Q4/2014: EUR 0.2m).

In Q1/2015, AIXTRON recorded a country specific tax expense of EUR 0.9m (Q1/2014: EUR 1.1m tax expense; Q4/2014: EUR 0.5m tax expense).

The Company's net result improved by EUR 2.3m year-on-year from EUR -11.8m in Q1/2014 (Q4/2014: EUR -19.1m) to EUR -9.5m in Q1/2015.

4.3. Development of Orders

Orders (in EUR million)	2015 Q1	2014 Q1	+/- mEUR	%
Total Order intake incl. Spares & Service	48.9	49.5	-0.6	-1
Equipment Order backlog (end of period)	79.0	64.2	14.8	23

As a matter of internal policy, the 2015 US dollar based equipment order intake and backlog are recorded at the current 2015 budget exchange rate of 1.25 USD/EUR (2014: 1.35 USD/EUR). In order to better reflect industry practice, Management has decided to start reporting total order intake including spares & service from January 1st, 2015 rather than continuing to report equipment order intake only. For comparison reasons, previous figures have been adopted to this new policy. Due to the generally quick turnaround of spares & services into revenues, the equipment order backlog figures will remain unchanged and continue to include equipment orders only.

In Q1/2015, total order intake including spares & service was stable year-on-year and sequentially at EUR 48.9m (Q1/2014: EUR 49.5m incl. spares & service; Q4/2014: EUR 49.3m incl. spares & service), reflecting current market demand.

The equipment order backlog of EUR 79.0m as at March 31, 2015 was 23% higher than the EUR 64.2m at the same point in time in 2014, and 14% higher than the 2015 opening backlog of EUR 69.0m.

As a matter of strict internal policy, 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:

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

In addition and reflecting current market conditions, 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 sufficient likelihood of realizing revenue on any specific system or that there is an unacceptable degree of risk of not realizing revenue on any specific system, Management will include or exclude the order, or a portion of the order, into or from the recorded order intake and order backlog figures, regardless of compliance with requirements of the points 1-4 above.

5. Financial Position and Net Assets

The Company recorded no bank borrowings as of March 31, 2015 and December 31, 2014.

Total equity as of March 31, 2015 increased by EUR 3.5m to EUR 419.2m compared to December 31, 2014 mainly due to currency translation effects. The equity ratio at 77% as of March 31, 2015, showed a slight decrease compared to 78% as of December 31, 2014, reflecting the results of the quarter.

The AIXTRON Group's capital expenditures for the first three months of 2015 amounted to EUR 3.5m (Q1/2014: EUR 4.0m; Q4/2014: EUR 4.0m), of which EUR 3.4m (Q1/2014: EUR 3.9m; Q4/2014: EUR 3.6m) 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 slightly to EUR 263.2m (EUR 124.0m + EUR 139.2m cash deposits) as of March 31, 2015 compared to EUR 268.1m (EUR 116.6m + EUR 151.5m cash deposits) as of December 31, 2014.

The value of property, plant and equipment was higher at EUR 79.4m as of March 31, 2015 (EUR 77.3m as of December 31, 2014) mainly due to additions of laboratory equipment as well as currency effects.

The value of goodwill at EUR 65.7m as per March 31, 2015 remained stable compared to EUR 64.8m as per December 31, 2014. There were no additions or impairments in the first three months of 2015. The minimal differences were solely due to exchange rate fluctuations.

The value of other intangible assets remained stable at EUR 2.3m as per March 31, 2015 (EUR 2.5m as per December 31, 2014).

The value of other current assets increased from EUR 7.7m as per December 31, 2014 to EUR 11.7m as per March 31, 2015 mainly due to short term timing effects including a short term loan of EUR 1.5m prior to the acquisition of PlasmaSi, Inc.

Inventories, including raw materials, unfinished and finished goods, increased to EUR 88.8m as per March 31, 2015, compared to EUR 81.7m as of December 31, 2014, mainly as a result of a higher order backlog.

Advance payments from customers increased by EUR 12.7m to EUR 79.6m as of March 31, 2015 compared to EUR 66.9m as of December 31, 2014, reflecting a higher order backlog and exchange rate effects.

Trade receivables at EUR 26.2m as of March 31, 2015, remained virtually stable compared to EUR 26.3m as of December 31, 2014, reflecting current business volume and currency related effects.

Other current provisions were down from EUR 28.1m as of December 31, 2014 to EUR 24.1m as of March 31, 2015, reflecting a progression of the restructuring process.

6. Opportunities and Risks

AIXTRON is exposed to a series of risks which are described in detail in the "Risk Report" of the Annual Report 2014 and in the section "Risk Factors" in AIXTRON's 2014 20-F Report, which has been filed with the U.S. Securities and Exchange Commission on February 24, 2015. Copies of the Company's most recent Annual Report and the 20-F Report are both available on the Company's website at www.aixtron.com (sections "Investors/Financial Reports" and "Investors/US-Listings"), the 20-F Report being additionally available on the SEC website at www.sec.gov.

During the first three months of 2015, AIXTRON Management was not aware of any significant additions or changes in the risks as described in the 2014 Annual Report/20-F Report referred to above.

7. Outlook

For ALD equipment to produce memory chips, Management expects an increase of demand in 2015. Management also sees near term equipment growth potential from an increasing penetration of GaN- and SiC-based power devices. Global demand for LEDs continues to increase driven by the increasing adoption of LEDs for general lighting applications. Despite this encouraging development, most AIXTRON LED customers currently remain reluctant to invest significantly into additional manufacturing capacity for LEDs. However, Management continues to expect an improving demand for MOCVD-production capacity as total demand for LEDs continues to increase. Nevertheless, the exact timing and extent of such a pickup of equipment demand persists in being difficult to predict.

Based on the results in the first quarter 2015 and the current assessment of AIXTRON's order situation, including risks and opportunities, Management reiterates its February revenue forecast of EUR 220 to 250 million for the fiscal year 2015.

As evidenced in Q1/2015 the overall financial performance in the fiscal year 2015 will be impacted by the successful positioning of the new AIX R6 tool and its production ramp up, as well as the execution of crucial R&D projects for its future technologies such as OLED, Power Electronics, Logic, etc. Nevertheless, Management expects to reach EBITDA break-even within the second half of the fiscal year with EBIT, net result and free cash flow continuing to improve significantly but remaining negative for the full year 2015. Management will continue its activities to increase efficiency with a particular emphasis on costs, margin contributions and the allocation of funds.

Management continues to expect that AIXTRON will still not require any external bank debt financing in 2015. Furthermore, the Company will also retain its strong equity base in the foreseeable future.

As of March 31, 2015, AIXTRON was not party to any legally binding agreements concerning financial participations, company acquisitions or disposals of business units.
