Management reiterates full year 2016 outlook

In Q3/2016, total order intake was EUR 69.0m (Q2/2016: EUR 51.1m). This order development is mainly attributable to stronger demand for LED, telecom and optoelectronic applications including orders from the sales of AIX R6 inventories with low margins. Equipment order backlog at the end of the third quarter 2016 was EUR 104.0m (June 30, 2016: EUR 86.2m).

This development supports the revenue growth expectation for the fourth quarter of 2016. Consequently, Management reiterates the full year 2016 guidance given in February 2016 for earnings and free cash flow expectations, but narrows the revenue guidance to EUR 180-200m and updates the order guidance to EUR 200-220m. The increase in order intake is primarily due to the sale of AIX R6 inventories with low margins. Further details to the outlook can be found in Chapter 6, “Outlook” of this report.

In Q3/2016, free cash flow was positive at EUR 3.0m (Q2/2016: EUR -20.7m), which is mainly attributable to reduced operating losses and higher advance payments from customers compared to Q2/2016.

Quarterly Statement as new Format of Quarterly Reporting

Due to the elimination of the obligation for quarterly reporting of public companies in Germany AIXTRON has decided to provide a shortened Quarterly Statement pursuant to Sect. 51a of the Exchange Rules for the Frankfurt Stock Exchange (“the BörsO FWB”).

Interim Management Report

1. Business Activity

AIXTRON’s business activity is described in detail in the section “1. Business Activity” of its 2016 Half-Year Group Financial Report. The Report is publicly available for download on the Company’s website at http://www.aixtron.com/en/investors/financial-reports/.

2. Business performance and key developments

2.1. Development of Orders

Equipment Orders	2016	2015	+/-
(in EUR million)	9M	9M	m EUR	%
Total order intake incl. spares & services	164.6	135.8	28.8	21
Equipment order backlog (end of period)	104.0	72.3	31.7	44

In Q3/2016, total order intake (including spares & service) was EUR 69.0m (Q2/2016: EUR 51.1m). This order development is mainly attributable to stronger demand for LED, telecom and optoelectronic applications including sales of AIX R6 inventories with low margins. Year-on-year, the stronger total order intake was mainly driven by demand for LED and optoelectronic applications. (Q3/2015: EUR 34.4m).

2.2. Exchange Rate Development of the US Dollar

The average exchange rate used by AIXTRON to translate income and expenses denominated in US dollars in the first nine months of 2016 was 1.11 USD/EUR (Q1/2016: 1.09 USD/EUR; Q2/2016: 1.13 USD/EUR; Q3/2016: 1.11 USD/EUR) compared to 1.12 USD/EUR in the same period of the previous year. Thus, compared to the previous year, the average US dollar exchange rate was broadly unchanged. As of September 30, 2016, the US-Dollar remained stable at 1.12 USD/EUR.

2.3. Development of Revenues

Total revenues recorded during the third quarter of 2016 were EUR 51.2m, down 6% compared to the same period last year (Q3/2015: EUR 54.6m). This year-on-year development resulted from comparatively stronger spares and service sales in Q3/2015. Compared to the previous quarter (Q2/2016: EUR 34.1m), revenues in Q3/2016 increased due to higher scheduled tool shipments, in particular for telecom and silicon industry applications. In the first nine months of 2016, total revenues at EUR 106.6m were down 21% compared to the previous year (9M/2015: EUR 135.3m) due to the comparatively lower revenues in the first half of 2016.

Equipment revenues in Q3/2016 were EUR 40.6m, representing 79% of the total Q3/2016 revenues. Compared to the same quarter last year, equipment revenues were largely stable (Q3/2015: EUR 41.3m or 76%; Q2/2016: EUR 24.7m or 73%). EUR 10.6m or 21% of total revenues were generated by the sale of spares and service in Q3/2016, decreased by 21% (Q3/2015: EUR 13.3m; Q2/2016: EUR 9.3m) due to exceptionally strong spares and service sales in Q3/2015.

Total	106.6	100	135.3	100	-28.7	-21

72% of total revenues in Q3/2016 were generated by sales to customers in Asia (Q3/2015: 61%; Q2/2016: 44%). 7% of revenues were generated in Europe (Q3/2015: 13%; Q2/2016: 33%) with the remaining 21% in the USA (Q3/2015: 26%; Q2/2016: 23%).

Cost of sales in Q3/2016 was EUR 34.2m or 67% of revenues. Compared to Q3/2015, cost of sales as percentage of revenues was similar (Q3/2015: EUR 36.8m, 67%; Q2/2016: EUR 27.2m, 80%). Compared to Q2/2016, the quarterly relative improvement in percent of revenues was due to a better product mix and better utilization of production capacities from higher volumes. Comparing cost of sales in percent of revenues between 9M/2016 and 9M/2015, the year-on-year improvement was due to a better product mix and the significant reduction of AIX R6 qualification costs.

Q3/2016 gross profit and gross margin developed accordingly (Q3/2016: EUR 16.9m at 33% gross margin; Q3/2015: EUR 17.8m; 33% gross margin; Q2/2016: EUR 6.9m; 20% gross margin).

Operating expenses in Q3/2016 increased to EUR 20.4m from EUR 16.3m in Q3/2015, mainly due to comparatively higher other operating income in Q3/2015 from a contractual compensation as well as from currency impacts (Q2/2016: EUR 18.0m).

	2016	2015
Key R&D Information	9M	9M	+/-
R&D expenses (million EUR)	39.6	41.1	-4	%

In Q3/2016, AIXTRON recorded a net currency expense of EUR 0.2m (Q3/2015: income of EUR 0.3m; Q2/2016: income of EUR 0.9m; 9M/2016: EUR 0.2m; 9M/2015: EUR 2.9m).

EBITDA in the third quarter 2016 of EUR -0.4m (Q3/2015: EUR 4.1m; Q2/2016: EUR -8.2m) was the result of above-mentioned effects. In the first nine months of 2016, EBITDA amounted to EUR -20.4m (9M/2015: EUR -17.6m).

The operating result (EBIT) decreased in a year-on-year comparison from EUR 1.5m in Q3/2015 to EUR -3.4m in Q3/2016 (Q2/2016: EUR -11.2m). In the first nine months of 2016, EBIT was EUR -29.3m (9M/2015: EUR -25.2m).

The Company’s net result in Q3/2016 amounted to EUR -3.8m (Q3/2015: EUR 0.3m; Q2/2016: EUR -11.1m; 9m/2016: EUR -30.4m; 9M/2015: EUR -27.3m).

3. Financial Position and Net Assets (Highlights)

The Company did not have any bank borrowings as of September 30, 2016 and December 31, 2015.

Table of Contents

3.1 Assets

Cash and cash equivalents (including cash deposits with a maturity of more than three months) amounted to EUR 163.5m (EUR 117.4m + EUR 46.1m cash deposits) as of September 30, 2016. Compared to EUR 209.4m (EUR 116.3m + EUR 93.1m cash deposits) as of December 31, 2015, the difference is mainly attributable to the negative net result, the payment of the second installment of the agreed return of advance payments to San’an and an agreed milestone payment of EUR 4.1m for the purchase of PlasmaSi (acquired in 2015) in Q1/2016. Compared to June 30, 2016, cash and cash equivalents increased slightly (June 30, 2016: EUR 161.3m) mainly due to reduced operating losses and higher advance payments received in the quarter.

Due to the higher revenues recorded at the end of the third quarter, trade receivables amounted to EUR 30.4m as of September 30, 2016, compared to EUR 26.0m as of December 31, 2015.

Inventories, including raw materials, unfinished and finished goods, increased to EUR 79.1m as per September 30, 2016, compared to EUR 70.8m as of December 31, 2015, mainly reflecting the strong equipment order backlog with high scheduled shipments in Q4/2016. The carrying value of AIX R6 inventories and outstanding supplier commitments amounted to EUR 19.3m as of September 30, 2016 (EUR 20.6m as of December 31, 2015, EUR 18.3m as of June 30, 2016). Orders were received for the majority of those inventories in Q3/2016 and will be shipped in the coming months.

3.2. Equity and Liabilities

As a result of the net loss reported in 9M/2016, total equity as of September 30, 2016 decreased by EUR 36.6m to EUR 359.9m compared to EUR 396.5m as of December 31, 2015. The equity ratio at 82% as of September 30, 2016, was stable compared to 82% as of December 31, 2015.

Advance payments from customers increased by EUR 17.3m to EUR 41.3m as of September 30, 2016 compared to EUR 24.0m as of December 31, 2015 reflecting the higher order backlog.

Other current liabilities were down from EUR 25.0m as of December 31, 2015 to EUR 2.4m as of September 30, 2016, reflecting the above-mentioned repayment to San’an as well as the payment related to the acquisition of PlasmaSi, Inc. in Q1/2016.

4. Cash Flow

The operating cash flow in Q3/2016 amounted to positive EUR 4.3m (Q3/2015: EUR -7.2m; Q2/2016: EUR -19.9m; 9M/2016: EUR -35.0m; 9M/2015: EUR -13.5m), mainly due to reduced losses and higher advance payments from customers compared to Q2/2016. For the same reasons, the free cash flow was also positive at EUR 3.0m in Q3/2016 (Q3/2015: EUR -10.0m; Q2/2016: EUR -20.7m; 9M/2016: EUR -38.0m; 9M/2015: EUR -22.3m).

5. Opportunities and Risks

A description of the Opportunities of the Company can be found in the chapter „Opportunities and Risks“of the 2016 Half-Year Group Financial Report which is publicly available for download on the Company’s website at http://www.aixtron.com/en/investors/financial-reports/.

A description of the Risks of the Company can be found in the “Risk Report” of the Annual Report 2015 and in the section “Risk Factors” in AIXTRON’s 2015 20-F Report, both of which are available on the Company’s website at www.aixtron.com (sections “Investors/Financial Reports” and “Investors/US-Listings”).

During the first nine months of 2016, AIXTRON Management was not aware of any significant additions or changes in the risks as described in the 2015 Annual Report/20-F Report referred to above.

6. Outlook

Total order intake in Q3/2016 as well as the respective order backlog support Management’s expectation of revenue growth in Q4/2016. Consequently, Management generally reiterates the full year 2016

Table of Contents

guidance given in February 2016 with slight adjustments for order intake and revenues.

Based on the assessment on AIXTRON’s current order situation, including current risks and opportunities as well as on the internal budget rate of USD/EUR 1.10, Management expects for fiscal year 2016 to achieve total revenues between EUR 180 and 200 million. Total 2016 order intake is expected to be in a range between EUR 200 and 220 million. The increase in total order intake is primarily due to low margin orders received for AIX R6 inventories.

Based on the internal budget rate of USD/EUR 1.10 and depending on the successful completion of qualification processes, market entry efforts as well as the achievement of revenues at the high end of the guidance range, Management expects to achieve another improvement of results in 2016. Before transaction related impacts, EBITDA, EBIT, net result and free cash flow are expected to improve slightly compared to 2015 but to remain negative for the full year 2016.

Due to uncertainties in terms of investment requirements for certain product groups, potential restructuring costs or consequences from the transaction, Management will review EBITDA development for 2017.

Further details on the outlook can be found in the chapter „Report on Expected Developments” of the Annual Report 2015 which is publicly available for download on the Company’s website at http://www.aixtron.com/en/investors/financial-reports/

AIXTRON has been named as a defendant in a putative class action commenced in the United States District Court for the Southern District of New York as described in detail in the “Report on Post-Balance Sheet Date Events” of the Annual Report 2015 and in the section “Legal Proceedings” of AIXTRON’s 20-F Report for fiscal year 2015.

8. PlasmaSi, Inc.

On April 1st, 2015, the Group acquired 100% of the voting equity interests of PlasmaSi, Inc. (USA), obtaining control of the company. During the first quarter of 2016, AIXTRON paid the outstanding contingent consideration of EUR 4,183k to the former shareholders of PlasmaSi, Inc.

9. Post-Balance Sheet Date Events

On October 21, 2016 the German Federal Ministry of Economic Affairs and Energy withdrew its clearance certificate, issued on September 8, 2016 for the takeover of AIXTRON by Grand Chip Investment GmbH. Should the takeover fail as a consequence of this, AIXTRON believes it is likely that the market capitalization of AIXTRON will fall substantially with the potential to cause an asset impairment. The estimated financial effect is dependent on the subsequent share price movements. There were no additional known business events after September 30, 2016 with a potentially significant effect on AIXTRON’s results of operation, financial position or net assets at September 30, 2016.
