BUSINESS DEVELOPMENT

Continuous acceleration of growth in Power Electronics Strong demand from all end markets FY/23 Growth Guidance reiterated

AIXTRON is seeing broad based and continued strong demand for tools needed in compound semiconductors. In particular, systems for the production of efficient power electronics based on gallium nitride (GaN) and silicon carbide (SiC) are extremely popular, which is reflected in an ever increasing order intake. In addition, orders for systems for micro LED and lasers as well as the after-sales business contributed to the high overall demand.

The Q1/2023 order intake of EUR 139.9 million reflects continuous demand for our tools at a very high level, 7% above the order intake in the same period of the previous year (Q1/2022: EUR 130.2 million). The equipment order backlog as of March 31, 2023, has increased to EUR 417.9 million (Q1/2022: EUR 260.4 million).

Revenues in the first quarter of 2023 at EUR 77.2 million were below the prior-year quarter (Q1/2022: EUR 88.6 million). This development was driven by the fact that export licenses for systems that are ready for delivery were not yet available as of the reporting date.

Due to the unabated strong demand and stable supply chains, Management expects further significant growth with increasing margins and order intake for the entire financial year and therefore confirms the 2023 guidance, announced in February.

In line with revenues, the gross profit of the first quarter of 2023 amounted to EUR 31.1 million (Q1/2022: EUR 35.9 million) at a gross margin of 40% (Q1/2022: 41%).

At EUR 27.6 million, operating expenses in Q1/2023 were higher than the corresponding figure of the previous year (Q1/2022: EUR 21.7 million) mainly due to higher R&D spending. With an operating result (EBIT) of EUR 3.5 million and an EBIT margin of 5% (Q1/2022: EUR 14.2 million, 16%), profit for the period in the first quarter of 2023 amounted to EUR 3.5 million (Q1/2022: EUR 13.8 million).

Free cash flow in Q1 2023 was EUR 1.9 million (Q1/2022: EUR 22.4 million). The deviation from the previous quarter was primarily driven by the lower profit for the period and the increase in inventories.

AIXTRON reported cash and cash equivalents including other current financial assets of EUR 327.5 million as of March 31, 2023 (December 31, 2022: EUR 325.2 million). The equity ratio at March 31, 2023 was 72% (December 31, 2022: 73%).

INTERIM MANAGEMENT REPORT (UNAUDITED)

Business Activity and Strategy

A detailed overview of the business activities and strategy of the AIXTRON Group ("AIXTRON" or "the Company") is provided in the Annual Report 2022. There were no changes in this regard in the first three months of fiscal year 2023. The report is publicly available on the Company's website at www.aixtron.com/en/investors/publications.

AIXTRON sees environmental protection as a key factor in the sustainability of its business model. This applies both to the company's own activities and to its suppliers. AIXTRON's innovative technologies and products make a decisive contribution to this. Against this background, AIXTRON has further expanded its activities in the area of Sustainability & ESG (Environment, Social, Governance). Further information can be found in our Sustainability Report (ESG Report) 2022 on the AIXTRON website at www.aixtron.com/en/investors/publications.

Results of Operations

Development of Orders

	Q1 2023	Q1 2022	+/-
in EUR million			M EUR	%
Total order intake incl. spares & services	139.9	130.2	9.7	7
Equipment order backlog (end of period)	417.9	260.4	157.5	60

Order intake for the first quarter of 2023 increased by 7% year-on-year to EUR 139.9 million (Q1/2022: EUR 130.2 million). This reflects the unabated high demand across almost all end markets, but in particular for efficient power electronics based on the material systems gallium nitride (GaN) and silicon carbide (SiC).

The total equipment order backlog as of March 31, 2023 was EUR 417.9 million, also significantly higher compared to the previous year (March 31, 2022: EUR 260.4 million).

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 three months of fiscal year 2023 was 1.07 USD/EUR (Q1/2022: 1.13 USD/EUR). Thus, compared to the same period of the previous year, the US dollar value increased by 5% in Q1/2023, having a corresponding positive impact on AIXTRON Group's US dollar denominated revenues and results in the period.

Development of Revenues

Total revenues for the first three months of fiscal year 2023 amounted to EUR 77.2 million and were EUR 11.4 million or 13% lower year-on-year (Q1/2022: EUR 88.6 million). This is mainly related to the fact that export licenses for systems that are ready for delivery were not yet available as of the reporting date.

In the first quarter of 2023, 64% of equipment revenues were generated with equipment for power electronics, with SiC applications accounting for the largest share. Another significant revenue share of 23% was contributed by the business with systems for optoelectronics, in particular for the production of lasers for optical data transmission and 3D sensing technology.

Equipment revenues in the first three months of fiscal year 2023 were EUR 56.4 million, representing 73% of the total revenues in the period (Q1/2022: EUR 66.3 million; 75%).

The remaining revenues were generated from the sale of spare parts and services.

Gross profit was EUR 31.1 million in first three months of fiscal year 2023 with a gross margin of 40% (Q1/2022: EUR 35.9 million or 41%; Q4/2022: EUR 82.2 million or 45%).

Operating expenses of EUR 27.6 million increased in the first three months of 2023 compared to the previous year (Q1/2022: EUR 21.7 million; Q4/2022: EUR 25.1 million). Increased R&D spending as well as higher personnel costs compared to the previous year have contributed to this development.

R&D expenses for the further development of existing and development of new tool generations in the first three months of 2023 increased by EUR 5.1 million to EUR 19.2 million (Q1/2022: EUR 14.1 million; Q4/2022: EUR 16.4 million).

Net other operating income and expenses resulted in an operating income of EUR 2.6 million in Q1/2023 (Q1/2022: EUR 1.8 million; Q4/2022: EUR 3.0 million). This reflects the income from fund investments in the amount EUR 1.3 million (Q1/2022: expense EUR 0.9 million) and R&D grants of EUR 0.9 million (Q1 2022: EUR 1.7 million).

The operating result (EBIT) declined year-on-year from EUR 14.2 million in Q1/2022 to EUR 3.5 million in Q1/2023 (Q4/2022: EUR 57.1 million). This development essentially results from the business and cost development described above.

The result before taxes in the first three months of 2023 was EUR 3.6 million (Q1/2022: EUR 14.3 million; Q4/2022: EUR 57.3 million).

Due to the development of earnings in the first three months of 2023, the tax expense of EUR 0.1 million was lower than in the prior year (Q1/2022: tax expense of EUR 0.5 million, Q4/2022: tax expense of EUR 7.1 million).

The Company's profit for the period in the first three months of 2023 amounted to EUR 3.5 million (Q1/2022: EUR 13.8 million; Q4/2022: EUR 50.3 million).

Financial Position and Net Assets

The Company did not have any bank borrowings as of March 31, 2023 as well as December 31, 2022.

Total equity as of March 31, 2023, increased to EUR 667.7 million compared to EUR 663.3 million as of December 31, 2022. The main influencing factors were the profit for the period. The equity ratio as of March 31, 2023, was 72% compared to 73% as at 31 December 2022 mainly due to the higher balance sheet total resulting from increased customer prepayments.

Cash, cash equivalents and other current financial assets increased to EUR 327.5 million as of March 31, 2023, compared to EUR 325.2 million as of December 31, 2022. In the first quarter, the inflows of trade receivables and advance payments from customers were almost fully offset by outflows related to the increase in inventories. In the first quarter of 2023, EUR 15.0 million were invested in funds. Other current financial assets as of March 31, 2023, now include total fund investments of EUR 236.6 million (December 31, 2022: EUR 220.4 million).

Property, plant and equipment, and leased assets as of March 31, 2023, increased to EUR 99.1 million compared to EUR 99.0 million as of December 31, 2022. Capital expenditures in the fiscal year mainly included laboratory equipment and lab as well as production site expansions.

Goodwill recognized was EUR 72.4 million as of March 31, 2023, compared to EUR 72.5 million as of December 31, 2022. There were no indications of impairment in the first three months of 2023. The changes in value compared with December 31, 2022 are attributable to exchange rate fluctuations.

Inventories, including raw materials, components, and work in progress, increased to EUR 295.0 million as of March 31, 2023, compared to EUR 223.6 million as of December 31, 2022. This development is related to inventory build-up in preparation for the higher expected business volumes in the upcoming quarters as well as to a lesser extent to stockpiling reflecting the fact that export licenses for systems that are ready for delivery were not yet available as of the reporting date.

Trade receivables as of March 31, 2023, amounted to EUR 62.5 million (December 31, 2022: EUR 119.7 million) and thus mainly reflect the current business volume in the first quarter of 2023 compared to the fourth quarter of 2022. The average day's sales outstanding of receivables were 56 days (December 31, 2022: 30 days).

Contract liabilities for advance payments amounted to EUR 162.3 million as of March 31, 2023, compared to EUR 141.2 million as of December 31, 2022, thus reflecting the current order situation.

Cash Flow

Free cash flow (cash flow from operating activities - investments in property plant & equipment as well as in intangible assets and non-current financial assets + proceeds from disposals) came in at EUR 1.9 million in first three months of 2023 (Q1/2022: EUR 22.4 million; Q4/2022: EUR -12.7 million). Significant cash flows in the first quarter of 2023 resulted from inflows of trade receivables and advance payments from customers as well as outflows from the build-up of inventories.

Opportunities and Risks

In the course of the first three months of 2023, the Executive Board has not identified any significant additions or changes to the opportunities and risks presented in the Annual Report for fiscal 2022. The risks arising from the current global crisis situations and market developments continue to be assessed as not significant because it has been shown that demand for our products has not been significantly affected and our supply chains, although strained, are nevertheless functioning reliably.

A description of the opportunities and risks of the AIXTRON Group can be found in the chapters "Risk Report" and "Opportunities Report" of the Annual Report 2022 which is publicly available for download on the Company's website at www.aixtron.com/en/ investors/publications.

Due to the continued positive assessment of the development of demand, the Executive Board reiterates its growth guidance for 2023.

Accordingly, Management expects total order intake for 2023 in a range between EUR 600 million and EUR 680 million. With revenues between EUR 580 million and EUR 640 million, the Executive Board expects to achieve a gross margin of around 45% at an EBIT margin of around 25% to 27%.

Further details on the annual guidance can be found in the "Expected Developments" section of the Annual Report 2022, which is available on the Company's website at www.aixtron.com/en/investors/publications.

Dividend

The Executive Board and Supervisory Board will propose to the upcoming Annual General Meeting on May 17, 2023, to distribute a dividend of EUR 0.31 per entitled share (2021: EUR 0.30 per share) from the accumulated profit of the fiscal year 2022. Taking into account the treasury shares and the new shares resulting from the exercise of stock options, both without dividend entitlement, this corresponds to an expected total distribution of EUR 34.8 million.

Financial Instruments

Other current financial assets include fund investments on EUR 236,580 thousand (31 December 2022 EUR 220,410 thousand) which are measured at fair value through profit or loss. The valuation is based on a market price that corresponds to hierarchy level 1.

All other financial assets and financial liabilities are measured at amortized cost. Their carrying amounts approximates their fair values.

Management
