Revenues and order intake increased in Q2/2017 / 2017 Revenue and Order Intake guidance raised / AIXTRON on track to return to profitability in 2018

Due to continuing demand for MOCVD systems driven mainly by capacity expansions in the areas of Vertical Cavity Surface Emitting Lasers ("VCSEL"), Red-Orange-Yellow (ROY) and specialty LEDs as well as for power electronics, order intake and revenues remain strong. AIXTRON therefore raises its revenue and order guidance for 2017 to EUR 210m – 230m from EUR 180m – 210m. Management also expects to achieve a positive free cash flow in 2017.

As expected, gross margin and EBIT in Q2/2017 were influenced by low margin shipments of the remaining AIX R6 GaN LED tools from inventory. Furthermore, Gross Margin was influenced by write downs caused by freezing the Company's Thin Film Encapsulation ("TFE") activities in the amount of EUR 1.3m; EBIT in the quarter was influenced by restructuring costs which included above mentioned write downs totaling EUR 7.7m. Free cash flow in the quarter was positive at EUR 7.0m. The establishment of a joint venture for the AIXTRON OLED deposition technology is ongoing and progressing. To support this, APEVA SE, a 100% subsidiary of AIXTRON SE, was founded. All AIXTRON SE employees working in the OLED product line, are planned to be transferred into this company on October 1st, 2017. AIXTRON continues to transform the Company to align R&D expenses with revenues in order to return to profitability in 2018. Please refer to Note 9 in this report for further information on restructuring costs.

Interim Management Report

1. Business Activity and Strategy

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 or organic semiconductor materials. Such components are used in a broad range of innovative applications, technologies and industries. These include LED applications, display technologies, data transmission, energy management and conversion, communication, signalling and lighting, metal coating as well as a range of other leading-edge technologies.

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 or other complex 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, energy storage and energy efficiency requirements and the necessity to reduce the cost of ownership 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 technologies for opto and power electronics include Metal-Organic Chemical Vapor Deposition ("MOCVD") for the deposition of compound materials to produce for instance LEDs, lasers, power electronics or other optoelectronic components. For thin film deposition technologies for organic electronics applications including Organic Light Emitting Diodes ("OLED"), AIXTRON offers Polymer Vapor Phase Deposition ("PVPD®") and Organic Vapor Phase Deposition ("OVPD®"). Plasma Enhanced Chemical Vapor Phase Deposition ("PECVD") technology is being employed for the deposition of complex Carbon Nanostructures (Carbon Nanotubes, Nanowires or Graphene). For logic and memory applications, AIXTRON systems are capable of depositing material films on wafers of up to 300mm in diameter for the production of memory chips, by employing technologies such as: Chemical Vapor Deposition ("CVD") and Atomic Layer Deposition ("ALD"). Additionally, MOCVD technology could be applied to deposit compound materials for the development of future logic devices.

The Company's R&D capability is of important strategic significance, as it provides for a competitive, leading edge 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 for applications such as specialty LEDs and for the production of wide band gap ("WBG") materials for Power Electronics. AIXTRON also targets to penetrate growth areas in the field of Organic Semiconductors.

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. AIXTRON SE's DIN EN ISO 50001:2011 certified energy management system and the EN ISO 14001:2004 certified environmental management system at AIXTRON, Inc. contribute to the efficient use of energy and the careful use of resources.

Management executes on the transformation of the Company. This includes the transfer of activities which are not considered core MOCVD technology for opto and power applications into clearly defined, independent units. In addition to the option to continue, Management will also consider the following options in order to achieve the financial independence of these activities: Freezing or terminating the activity, sale or continuation of the unit together with a partner. The following measures have already been implemented or initiated: TFOS and TFE have been frozen; ALD/CVD has been sold, pending regulatory approvals of the U.S. and Korean authorities, to Eugene Technology, South Korea. APEVA SE has been founded as a subsidiary of AIXTRON SE in order to facilitate the transfer of the OLED activities into an independent unit.

2. Macroeconomic and Industry Developments

Macroeconomic developments

Global economic growth is picking up but its potential is limited by persistent structural problems. Investment activity, manufacturing and trade are recovering, stabilizing commodity prices are easing pressure on commodity exporting economies to some extent. While advanced economies are doing quite well, yet on a lower level since the global financial crisis, the recovery is mainly driven by the emerging and developing countries. Yet, growth there is uneven and problems such as high debt levels, adjustments to structurally lower commodity prices or geopolitical tensions are to be solved. In addition, there is an increased danger of protectionist policies, especially in the advanced economies, which might have a clearly negative effect on global growth through reduced trade and crossborder investment activity. The International Monetary Fund (IMF) in its World Economic Outlook (published April 18, 2017) increased its global growth forecast for 2017 by 0.1 percentage points to 3.5% (2016: 3.1%). While growth in the advanced economies is now projected at 2.0% (2016: 1.7%) the emerging and developing countries are expected to grow by 4.5% (2016: 4.1%).

AIXTRON is much more dependent on industry specific cycles than on the general economic cycle and again therefore does not expect major impacts from the global economic environment on its business development in 2017.

The average exchange rate used by AIXTRON to translate income and expenses denominated in US dollars in the first six months of 2017 was 1.09 USD/EUR (Q1/2017: 1.07 USD/EUR; Q2/2017: 1.12 USD/EUR), which compares to 1.11 USD/EUR in H1/2016. Thus, compared to the same period of the previous year, the average US dollar exchange rate improved by 2 percent in H1/2017. Recently, the US Dollar weakened resulting in an average US dollar exchange rate of 1.12 USD/EUR in Q2/2017. As of June 30, 2017, the US-Dollar was weaker at 1.141 USD/EUR compared to the previous year's closing price of 1.055 USD/EUR. If this trend continued then this would negatively impact the results of the coming quarters.

Industry developments

According to the market research institute IHS (at the end of February 2016), the market for WBG Gallium nitride (GaN) and Silicon Carbide (SiC) based power management devices is expected to grow from 231 million shipped units in 2015 to 2.0 billion shipped units in 2025. IHS viewed that SiC will account for the majority of WBG shipments power management devices, as SiC adoption could be accelerated by the hybrid and electric vehicle market growth. Leading power semiconductor makers have developed SiC based devices. This year marked a new milestone with some industry players preparing for mass production of SiC MOSFETs for mainstream adoption by various applications including solar power inverters, uninterrupted power supplies (UPS), EV charging stations and onboard chargers (OBC).

According to LEDinside, fine-pitch LED display is undoubtedly the LED product category expected to achieve the highest growth in the next few years. The fine pitch LED display market is expected to increase from USD 854 million in 2016 to 1,770 million in 2021, achieving a Compounded Annual Growth Rate ("CAGR") of 16% between 2016 and 2021.

In recent months numerous industry and capital market analysts have been speculating that leading smartphone OEMs could soon introduce vertical-cavity surface-emitting laser ("VCSEL") based 3D sensing functionalities which have the potential to boost personalized services. Capital market analysts believe that current MOCVD manufacturing capacities for Gallium Arsenide (GaAs) VCSEL devices may not be sufficient due to significant unit growth being expected. Automotive and Datacom applications could grow by 21% CAGR until 2021 (from USD700m to USD2.4bn in 2021). Further they anticipate that coming generations of mobile phones to be equipped with 3D sensors within 2017.

3. Business Performance and Key Developments

Revenues and orders received in the first half of 2017 were up driven by the improved demand for MOCVD systems to produce VCSEL, ROY and specialty LEDs as well as power electronics and CVD systems for the production of flash memory applications.

Total order intake and equipment order backlog both of which increased sequentially in a quarterly comparison as well as year-on-year. Management's view of the positive momentum in orders and revenues has resulted in an increased guidance for 2017.

Compared to the previous quarter, Revenues in Q2/2017 increased to EUR 60.6m (Q1/2017: EUR 53.6m). Due to relatively stable cost of sales compared to revenues, the gross profit was EUR 14.7m with a gross margin of 24% (Q1/2017: EUR 13.6m; 25%). This amount includes a write down related to the TFE activities of EUR 1.3m. Operating expenses in Q2/2017 including the TFE related write-downs of EUR 5.1m were lower compared to the previous quarter which included the TFOS related write-downs of EUR 5.6m, leading to an EBITDA in Q2/2017 of EUR -4.2m (Q1/2017: EUR 6.0m). The operating result (EBIT) was EUR -11.3m with an EBIT margin of -19% (Q1/2017: EUR 12.7m; -24%). The net result amounted to EUR -11.4m (Q1/2017: EUR -13.5m).

Free cash flow in Q2/2017 was positive at EUR 7.0m (Q1/2017: EUR 33.3m).

AIXTRON reported cash and cash equivalents (including bank deposits with a maturity of more than 90 days) of EUR 197.1m as of June 30, 2017, which is EUR 37m higher than the EUR 160.1m recorded on December 31, 2016. The difference is mainly attributable to the collection of trade receivables and advance payments from customers.

4. Results of Operations

4.1. Development of Orders

Equipment Orders (in EUR million)	H1/2017	H1/2016	+/-	%
Total Order intake incl. Spares & Service	128.5	95.5	33.0	34
Equipment Order backlog (end of period)	93.4	86.2	7.2	8

As a matter of internal policy, the 2017 US dollar based equipment order intake and backlog are recorded at the current 2017 budget exchange rate of 1.10 USD/EUR (2016: 1.10 USD/EUR).

In H1/2017, order intake showed a year-on-year increase of 34% to EUR 128.5m (H1/2016: EUR 95.5m). This was mainly driven by improved demand for MOCVD systems for VCSEL, Red-Orange-Yellow and specialty LEDs as well as power electronics and CVD systems for flash memory. In Q2/2017, total order intake came in at EUR 66.6m, 8 percent higher compared to the previous quarter (Q1/2017: EUR 61.9m). This order development is mainly driven by increased demand from LED and optoelectronic as well as memory applications.

The equipment order backlog of EUR 93.4m as at June 30, 2017 was higher both than the EUR 86.2m at the same point in time in 2016 and the Q1/2017 backlog of EUR 87.6m. The majority of the backlog is due for shipment in 2017.

As a matter of strict internal policy, AIXTRON follows clear 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,
• 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 the requirements of the points 1-4 above.

4.2. Development of Revenues

During the first six months of 2017, AIXTRON recorded total revenues of EUR 114.1m, an increase of EUR 58.6m or 106% compared to the same period last year (H1/2016: EUR 55.5m) reflecting improved demand for MOCVD systems for VCSEL, Red-Orange-Yellow and specialty LEDs as well as power electronics and CVD systems for flash memory applications. Compared to the previous quarter, revenues in Q2/2017 increased to EUR 60.6m (Q1/2017: EUR 53.6m).

Equipment revenues in H1/2017 were EUR 94.4m, representing 83% of the total H1/2017 revenues (H1/2016: 36.6m; 66%). In the second quarter 2017, equipment revenues amounted to EUR 50.9m or 84% of revenues (Q2/2016: EUR 24.7m; 72%; Q1/2017: EUR 43.5m; 81%).

The deposition equipment and upgrades bought by AIXTRON's customers in the first half-year 2017 are predominantly used for the production of LEDs, including ROY and specialty LEDs. The second largest end-market in terms of revenues for AIXTRON equipment in the first half-year of 2017 was CVD equipment used for the production of memory devices.

In a yearly comparison, cost of sales in H1/2017 increased to EUR 85.8m (75% of revenues) compared to EUR 45.5m (82% of revenues) in H1/2016. H1/2017 cost of sales include low margin AIX R6 sales from inventory in the first half 2017 as well as a write down of EUR 1.3m related to the TFE activities in Q2/2017 and a write down of EUR 1.0m related to the TFOS activities during Q1/2017. The improvement in cost of sales relative to revenues mainly reflects the corresponding revenue levels. The quarterly sequential increase in cost of sales from EUR 40.0m (75% of revenues) in Q1/2017 to EUR 45.9m (76% of revenues) in Q2/2017 was mainly due to the revenue development as well as the previously described TFE related write downs in Q2/2017.

The Company's gross profit in H1/2017 was EUR 28.3m (H1/2016: EUR 10.0m), resulting in an improved gross margin of 25% (H1/2016: 18%). In a quarterly comparison, the gross profit in Q2/2017 improved sequentially to EUR 14.7m (Q1/2017: EUR 13.6m), due to above mentioned reasons. Q2/2017 gross margin was 1 percentage point lower than the previous quarter at 24% (Q1/2017: 25%; Q2/2016: 20%).

Operating costs in H1/2017 of EUR 52.4m were 46% higher year-on-year compared to EUR 35.9m in H1/2016, including restructuring costs of EUR 12.1m including the write downs related to the TFOS and TFE activities. In a quarterly sequential comparison, operating costs were slightly down to EUR 25.9m compared to EUR 26.4m in Q1/2017.

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

Selling expenses in H1/2017 were down 10% year-on-year in absolute terms to EUR 5.3m (H1/2016: 5.8m) and improved relative to revenues to 5% (H1/2016: 10%). Sequentially, selling expenses were stable at EUR 2.7m (Q1/2017: EUR 2.6m). In Q2/2017, selling expenses relative to revenues were 4% (Q1/2017: 5%).

In H1/2017, general and administration expenses were up by 13% year-on-year to EUR 9.4m (H1/2016: EUR 8.3m). In Q2/2017, general and administration expenses increased sequentially to EUR 5.1m (Q1/2017: EUR 4.3m). The agreed sale of the ALD/CVD memory product line to Eugene Technology as well as other reorganizational measures incurred legal and other fees in the amount of EUR 1.3m in Q2/2017.

Research and development costs in H1/2017 adjusted by TFOS and TFE related write downs totaling EUR 10.6m, increased by 10% year-on-year to EUR 28.8m (H1/2016: EUR 26.0m). Sequentially, adjusted R&D costs in Q2/2017 at EUR 14.7m (Q2/2017 adjusted by EUR 5.1m) were slightly higher compared to EUR 14.1m in Q1/2017 (Q1/2017 adjusted by EUR 5.6m).

Recent examples of R&D activities with involvement of AIXTRON are the "SiTaSol" project and the "KoReMO" project, both aiming at reduced cost and increased efficiency in solar cell production technologies. Within the SiTaSol project, started in May 2017, seven European research partners strive to increase conversion efficiencies of crystalline silicon wafer solar cells by combining them with solar cells based on III-V materials. The KoReMo project, launched in March 2017, focuses on production aspects of III-V high-performance solar cells. Such solar cells are mainly being used in industrial applications, due to the high efficiencies exceeding 40%. The five project partners aim at a significantly more cost-effective process chain for these highly efficient III-V solar cells. Ultimately, projects such as SiTaSol and KoReMo target to strengthen the market position of the European semiconductor industry against its competitors from the USA and Asia.

Net other operating income and expenses in the first half-year of 2017 resulted in an income of EUR 1.7m (H1/2016: EUR 4.2m income). In Q2/2017, net other operating income and expenses were up to EUR 1.5m income (Q1/2017: income of EUR 0.2m).

EUR 1.2m of R&D grants received in H1/2017 (H1/2016: EUR 1.2m; Q2/2017: EUR 0.7m; Q1/2017: EUR 0.4m), were recorded as other operating income.

The EBITDA in the first half-year 2017 improved both compared to the previous year (H1/2017: EUR -10.2m, H1/2016: EUR -20.0m) and sequentially (Q2/2017: EUR -4.2m; Q1/2017: EUR -6.0m).

The H1/2017 operating result (EBIT) adjusted by restructuring costs of EUR 14.5m, was EUR -9.6m. Compared to the previous year, EBIT was up mainly due to above mentioned effects (H1/2016: EUR -25.9m). Compared to the previous quarter, the operating result in Q2/2017 adjusted by EUR 7.7m, improved to EUR -3.6m (Q1/2017: EUR -5.9m; adjusted by EUR 6.8m).

Due to the above-mentioned developments, result before taxes improved from EUR -25.6m in H1/2016 to EUR -23.8m in H1/2017. The result before taxes in H1/2017 includes a net finance income of EUR 0.3m (H1/2016: EUR 0.2m; Q2/2017: EUR 0.1m; Q1/2017: EUR 0.2m).

5. Financial Position and Net Assets

The Company did not have any bank borrowings as of June 30, 2017 or December 31, 2016.

Total equity as of June 30, 2017 decreased to EUR 339.8m compared to EUR 369.7m as of December 31, 2016 mainly due to the period's net loss. The equity ratio was 82% as of June 30, 2017 (85% as of December 31, 2016).

The AIXTRON Group's capital expenditures for the first six months of 2017 amounted to EUR 3.6m (H1/2016: EUR 1.7m), of which EUR 3.3m (H1/2016: EUR 1.4m) 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) were EUR 197.1m (EUR 169.3m + EUR 27.8m cash deposits) as of June 30, 2017. Compared to EUR 160.1m (EUR 120.0m + EUR 40.0m cash deposits) as of December 31, 2016, the difference of EUR 37.0m reflecting the operational performance resulting from a reduction of trade receivables and an increase of advance payments from customers.

Property, plant and equipment was lower at EUR 65.3m as of June 30, 2017 (EUR 74.2m as of December 31, 2016) mainly due to regular and accelerated depreciation of laboratory equipment in the first six months of 2017.

Goodwill was EUR 68.7m as per June 30, 2017 lower than the EUR 74.6m as per December 31, 2016. There were no impairments in the first half of 2017. Please refer to Note 8 in this report for further information on assets classified as held for sale. The remaining difference was mainly related to exchange rate fluctuations.

Inventories, including raw materials, unfinished and finished goods, decreased to EUR 36.4m as per June 30, 2017 (December 31, 2016: EUR 54.2m). This figure is a reflection of an improved inventory management and shipments of AIX R6 tools from inventory. Please refer to Note 8 in this report for further information on assets classified as held for sale.

On May 25, 2017, AIXTRON, Inc. entered into an agreement for the sale of the assets of the ALD and CVD memory product line, mainly based at AIXTRON, Inc. in Sunnyvale, California to Eugene Technology Inc. The sale is subject to regulatory approvals including CFIUS in the U.S. The CFIUS filing was made on July 17, 2017. Please refer to Note 8 in this report for further information on assets classified as held for sale.

Advance payments from customers increased by EUR 7.5m to EUR 33.6m as of June 30, 2017 compared to EUR 26.1m as of December 31, 2016 reflecting the order intake recorded in H1/2017.

Trade receivables amounted to EUR 22.0m as of June 30, 2017, compared to EUR 60.2m as of December 31, 2016, representing 33 days sales outstanding.

6. Opportunities and Risks

AIXTRON expects the following market trends and opportunities in the relevant end user markets could possibly have a positive effect on future business:

Short Term

• Further increasing emergence of compound semiconductor based laser devices such as VCSELs for sensors in automotive and mobile applications.
• Further increasing emergence of compound semiconductor based laser devices for ultrafast Telecom and Datacom infrastructure and data center applications.
• Further increasing adoption of LEDs and specialty LEDs (in particular Red-Orange-Yellow, UV or IR) for Sensor, Fine Pitch Display and other applications.
• Increased emergence of wide band gap SiC based devices for energy efficient power management in automotive, consumer electronics and mobile applications.

Mid- to Long-Term

• Increased emergence of wide band gap GaN based devices for energy efficient power management and communications in automotive, consumer electronics and mobile applications.
• Increasing emergence of compound semiconductor based sensor devices for autonomous driving.
• Further progress in the development of GaN-on-Silicon LEDs and Wafer Level Packaging.
• Development of new wide band gap applications such as RF and System-on-Chip with integrated power management.
• Progress in the development of large area OLED displays requiring efficient deposition technologies such as OVPD.
• Increased development activity for specialized compound solar cell applications.
• Development of applications using Carbon Nanostructures (Carbon Nanotubes, Carbon Nanowires, Graphene, 2D-Materials).
• Development of alternative LED applications such as Visual Light Communication technology or Micro-LED Displays.

A description of the Opportunities and Risks of the Company can be found in the chapter "Opportunities and Risk Report" of the Annual Report 2016 which is publicly available for download on the Company's website at http://www.aixtron.com/en/investors/financial-reports/.

The sale of the ALD/CVD product line to Eugene Technology, South Korea is subject to regulatory approvals, in particular by the Committee on Foreign Investments in the United States (CFIUS) which is considered as a transactional risk.

The Company generates a significant portion of its revenues in currencies other than the Euro. As a result, further weakening of the US Dollar to the Euro may negatively affect the Company's business as well as the business of AIXTRON's customers and suppliers.

During the first six months of 2017, AIXTRON Management was not aware of any further significant additions or changes in the risks as described in the 2016 Annual Report referred to above.

7. Outlook

Based on the assessment on AIXTRON's order intake, Management now expects for fiscal year 2017 to achieve revenues and an order intake between EUR 210 million and 230 million.

AIXTRON continues to transform the Company to align R&D expenses with revenues in order to return to profitability in 2018. As the execution of this strategy might have a substantial influence on profit, Management is not guiding on EBITDA, EBIT and net result for fiscal year 2017. Management will provide an update on the 2017 earnings outlook as the above-mentioned plans and measures materialize.

Management expects to achieve a positive free cash flow in 2017 and a positive EBIT for 2018.
