1. Comments on the condensed consolidated interim financial statements

1.1 Summary of most important developments

The following discussion and analysis of the financial condition and results of operations should be read in conjunction with the Group's consolidated financial statements for the year ended December 31, 2020.

Highlights

In the first half of 2021, total revenue amounted to USD 316,375 thousand (first half of 2020: USD 245,650 thousand), an increase of 28.8% compared to the same period in the previous year. Business continued to develop strongly throughout the first half of 2021 and across all end markets.

Revenue in X-FAB's core business, namely automotive, industrial, and medical, came in at USD 252,991 thousand (first half of 2020: USD 189,637 thousand), an increase of 33.4% compared to the same period in the previous year.

X-FAB's core business generated 80.0% of total revenue (first half of 2020: 77.2%).

Consumer, Communications & Computer business ("CCC business") came in at USD 62,954 thousand (first half of 2020: USD 55,564 thousand). This is a year-on-year increase of 13.3%.

Revenue analysis

In the first half of 2021, demand continued to be driven by the ongoing recovery after the COVID-19-related weakness in 2020 but also by the introduction of new business. Interest in X-FAB's specialty technologies is strong as they enable smart solutions that are key to address the challenges facing society today. These include the climate change with the need for greener energy and transportation (SiC); the COVID-19 era as well as aging societies with the need for fast and reliable point-of-care diagnostics (lab-on-chip), and globalization and connectivity requiring all kinds of sensor applications.

The Group has received support under short-term working and other government support schemes introduced in various countries to alleviate the economic effects of the COVID-19 pandemic. However, with the exception of the government support of USD 6,563 thousand (first half of 2020: none) reported as a deduction from cost of sales, the amounts received did not have a significant effect on the results of the Group in the first half of the financial period 2021 or in the comparative period. Government support to alleviate the economic effects of the COVID-19 pandemic subsidies are designed to offset ongoing operating costs and are recognized as a deduction of cost of sales, research and development expenses, and general and administration expenses as appropriate, and have been recognized in period consistent with the costs incurred that they are intended to offset provided it is reasonably assured that the Group has been, and will continue to, be in compliance with the terms and conditions to obtain and retain those subsidies. The ongoing commitments under the terms of those subsidies are not significant to the Group's operations.

There have been no significant effects on the Group's balance sheet as a result of the COVID-19 pandemic. There has been no significant effect on the carrying value or fair values of financial instruments arising from the COVID-19 pandemic.

In responding to the COVID-19 pandemic the Group's primary priority has been to ensure the health and wellbeing of X-FAB's employees with a variety of safety measures implemented at all locations, ultimately contributing positively to the continuity of production.

Cost of sales

Costs of sales include material expenses such as raw materials, the costs of maintaining fixed assets, depreciation, staff costs and cost for external services. In 2021, cost of sales increased by USD 19,288 thousand or 8.8% compared to the first half of 2020 as a consequence of the increase in revenue. Cost of sales are reported after deducting USD 6,563 thousand (first half of 2020: none) of government support received in the first half of the financial year 2021 to offset direct salary and production-related costs incurred in 2020 as part of a program to offset the impact of the COVID-19 pandemic (further details are provided in note 2.5.5.12 in the notes to the condensed consolidated interim financial statements).

Research and development expenses

Research and development expenses amounted to USD 17,174 thousand in the first half of 2021, representing 5.4% of revenue (first half of 2020: USD 11,791 thousand, 4.8% of revenue). The increase of 45.6% (USD 5,383 thousand) compared to the previous year's six-month period is more than proportionate to the change in revenue in 2021. Research and development expenses include grants in the amount of USD 5,020 thousand compared to USD 8,057 thousand in the first half of 2020. The Group's research and development activities focus on development of new fabrication processes, optimization of existing processes using the Group's key process technologies and development of new integrated circuit features in order to meet the customers' analog/mixed-signal needs.

General, administrative, and selling expenses

General and administrative expenses and selling expenses increased by USD 1,149 thousand (6%) compared to the first half of 2020. The increase was primarily driven by the increase in business.

Financial result

Net financial costs decreased by USD 4,268 thousand in the first half of 2021 compared to the previous year due to lower expenses arising from currency exchange losses and lower interest expenses.

Net income

The Group recorded a profit for the period for the first half of 2021 of USD 39,502 thousand compared to a loss of USD 12,611 thousand in the first half of 2020.

The announcement of third quarter results will take place on October 28, 2021.

1.2 Risk factors

The following risk factors may affect X-FAB's business, financial condition, and results of operations; the list is not exhaustive:

• Structural trends in the markets for the end-user products produced by X-FAB's customers, or material volatility in demand for these products, may limit X-FAB's ability to maintain or increase sales and profit levels. A global systemic economic or financial crisis, increased political uncertainty, or increased economic protectionism could negatively affect X-FAB.
• A significant portion of X-FAB's revenue comes from a relatively limited number of customers, with its largest customer being a related party.
• Due to X-FAB's relatively fixed-cost structure, its ability to grow profitability is dependent on its ability to maintain appropriate utilization levels.
• X-FAB faces difficulties in forecasting demand and may therefore be unable to match its production capacity to demand.
• X-FAB may be unsuccessful in its attempts to increase its production capacity and capabilities.
• X-FAB may not realize all the anticipated benefits from its acquisition of Altis' core business.
• X-FAB's expectations of an increase in market share by foundries might not occur.
• X-FAB may face increasing competition.
• X-FAB may face competitive pricing pressures.
• X-FAB may face raw material price increases.
• X-FAB is subject to risks associated with currency fluctuations.
• X-FAB is subject to risks associated with any form of cyber criminality.

2.5 Notes to the condensed consolidated interim financial statements

2.5.1 Company information

X-FAB Silicon Foundries SE (hereafter referred to as "X-FAB SE," "the parent," "the Company," or "the parent Company" and, together with its subsidiaries, as "X-FAB SE Group" or "the Group") is a European limited company (Societas Europaea/SE) registered under the number BE0882.390.885 in Hasselt, Belgium. The Company is a holding company for the Group's investments in pure-play semiconductor wafer companies. The Company's registered address is Transportstraat 1, 3980 Tessenderlo, Belgium.

The X-FAB SE Group is one of the world's leading pure-play foundry providers specializing in analog/mixed-signal technologies. As a pure-play foundry, the Group develops its own technologies, offering its customers a comprehensive range of product development (design support) and production services. The X-FAB SE Group manufactures integrated circuits to customers' designs, supplying these in the form of silicon wafers.

2.5.2 Basis of preparation

2.5.2.1 Statement of compliance

These condensed interim consolidated financial statements have been prepared in accordance with International Financial Reporting Standard (IFRS) IAS 34 Interim Financial Reporting as endorsed by the European Union. They do not include all of the information required for full annual financial statements and should be read in conjunction with the Group's last annual consolidated financial statements as at and for the year ended December 31, 2020.

The condensed consolidated interim financial statements of X-FAB SE Group were authorized for issue in accordance with a resolution of the directors on September 2, 2021.

2.5.2.2 Use of estimates and judgements

In preparing these condensed consolidated interim financial statements management has made judgements, assumptions, and estimates that affect the application of accounting policies and the reported amounts of assets, liabilities, income, and expenses. Actual results may differ from these estimates.

Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimates are revised and in any future periods affected. The significant judgements made by management in applying the Group's accounting policies and the key sources of estimation uncertainty were the same as those that applied to the consolidated financial statements as at and for the year ended December 31, 2020.

Measurement of fair values

A number of the Group's accounting policies and disclosures require the measurement of fair values, both for financial and non-financial assets and liabilities.

If third party information is used to measure fair values, the evidence obtained from third parties is assessed to support the conclusion that such valuations meet the requirements of IFRS, including the level in the fair value hierarchy in which such valuations should be classified.

When measuring the fair value of an asset or a liability, the Group uses market observable data as far as possible.

Fair values are classified into different levels in a fair value hierarchy based on the inputs used in the valuation techniques as follows:

Level 1: quoted (unadjusted) prices in active markets for identical assets or liabilities.
Level 2: other techniques for which all inputs that have a significant effect on the recorded fair value are observable, either directly or indirectly.
Level 3: techniques that use inputs which have a significant effect on the recorded fair value that are not based on observable market data.

If the inputs used to measure the fair value of an asset or a liability might be categorized in different levels of the fair value hierarchy, then the fair value measurement is categorized in its entirety in the same level of the fair value hierarchy as the lowest level input that is significant to the entire measurement.

The Group measures transfers between levels of the fair value hierarchy at the end of the reporting period during which the change has occurred.

2.5.3 Summary of significant accounting policies

The accounting policies applied are consistent with those applied in the annual consolidated financial statements ended December 31, 2020.

Exchange rate expenses primarily include amounts of USD 4,511 thousand (2020: USD 4,476 thousand) resulting from the translation of cash balances denominated in Malaysian ringgit and loans and cash balances denominated in euros.

2.5.5.5 Income taxes

Income tax expense is recognized at an amount determined by multiplying the profit before tax for the interim reporting period by the expected effective tax rate of the year.

The income tax expense comprised the following:

in thousands of U.S. dollars	For the six months ended June 30
	2021	2020
Current taxes:
Actual income tax charge for the period	(2,436)	(871)
Adjustment of prior years' tax charges	-	-
	(2,436)	(871)
Deferred taxes	2,831	(674)
Total	395	(1,545)

Changes in recognized deferred tax assets resulted in an increase of deferred tax assets of USD 2,831 thousand (2020: decrease of USD 674 thousand). The increase in deferred tax assets is mainly due to recognition of previously unrecognized deferred tax assets arising on property, plant, and equipment in Malaysia amounting to USD 2,857 thousand (2020: derecognition of USD 660 thousand), which is the estimated pro-rata amount of the expected recognition for the full financial year 2021. The assumptions made and the method applied to calculate deferred taxes were consistent with the methods used at December 31, 2020. The actual income tax expense for the period primarily consists of accruals made for income taxes for the year to be paid in Malaysia, France and Germany.

2.5.5.6 Earnings per share

The earnings per share is calculated by dividing the profit for the period attributable to the ordinary shareholders (as reported in the condensed interim statement of profit and loss and other comprehensive income) by the weighted average number of shares in issue during the period.

There were 130,781,669 shares in issue at January 1 and June 30 in both periods, and the weighted average number of ordinary shares outstanding was 130,631,921 in both periods.

There are no diluting effects on the earnings per share in the current or previous period.

Total	59,220	76,209

Current loans and borrowings	24,321	31,796
Non-current loans and borrowings	34,899	44,413

A bank loan with a carrying value of USD 6,563 thousand at December 31, 2020 has been derecognized and reported in the first half of the financial year 2021 as a deduction from cost of sales. The loan, obtained and paid to X-FAB Texas in 2020, was issued under the "Paycheck Protection Program" established by the US federal government's Coronavirus Aid, Relief, and Economic Security Act to secure payroll and utility payments. Under the terms of the program, the borrower was entitled to apply for forgiveness of the loan by December 31, 2020, provided certain conditions regarding retention and rehiring of employees are met and provided the Government still has sufficient budget available to forgive those loans. An application for forgiveness of the bank loan was made in the financial year 2020 and was approved on June 10, 2021. Accordingly the balance on the loan was released to income and was offset against cost of sales matching the classification of the costs – direct production related costs - which were financed under the program.

The movement in loans and borrowings include income for realized and unrealized exchange rate gains of USD 1,255 thousand (2020: losses of USD 356 thousand) resulting from the effect of changes on exchange rates of eurodenominated loans. Loans and lease obligations totaling USD 14,552 thousand (2020: USD 15,749 thousand) have been repaid in the first six months of 2021. The Group concluded new loans and overdrafts in the first half of 2021 in the amount of USD 4,479 thousand.

The provisions for restructuring are attributable to a provision made in December 2020 for the costs associated with a restructuring plan which is being implemented at the Group's French location due to falling demand for certain legacy products which were manufactured at the location prior to its acquisition by X-FAB and the smooth first industrial development ramp up of X-FAB technologies. Following announcement of the plan on December 10, 2020, the Group recognized a provision of USD 5,722 thousand for expected restructuring costs. The expected restructuring costs primarily include employee termination benefits and are based on a detailed plan agreed between management and employees' representatives. Costs of USD 763 thousand have been incurred and offset against this provision in the first half of the financial year. There have been no increases or releases of amounts provided since December 31, 2020. The restructuring is expected to be completed by December 31, 2021.

The restructuring costs were included in general and administration expenses.

Warranty provisions are estimated based on the Group's experience of past claim rates and knowledge of current claims together with an assessment of rectification costs.

Non-current provisions refer to anniversary bonuses for employees accounted for in accordance with IAS 19, which include estimates of future staff turnover, based on the Group's experience of staff turnover rates in recent years.

2.5.5.17 Financial instruments – fair values and risk management

Financial instruments measured at amortized cost

The carrying amount of cash and cash equivalents, bank overdrafts, trade and other receivables, and trade payables approximates their fair value due to the short-term maturity of these financial instruments.

The fair value of the Group's non-current liabilities is based on their present values calculated by discounting future cash flows at current rates of interest available for debt with the same maturity profile.

The Group's principal financial instruments not carried at fair value are cash and cash equivalents, trade receivables, other current assets, other non-current assets, trade and other payables, bank overdrafts, and long-term borrowings.

Financial instruments measured at fair value

Financial assets and liabilities accounted for at fair value through profit or loss

The Group held no financial instruments measured at fair value in the financial year. The Group's financial instruments measured at fair value held in the previous year consisted of an equity investment in a company listed on the NASDAQ stock exchange. The fair value of the equity investment in a company listed on the NASDAQ stock exchange was, until its sale in 2020, based on the price quoted for those shares at the respective reporting dates. Changes in the fair value of this investment were recorded in profit or loss, although the investment was not held for trading purposes, as the Group did not opt to present fair value changes in other comprehensive income.

The Group held no forward foreign exchange contracts or interest rate swaps in the reporting period.

There have been no transfers of assets or liabilities between levels of the fair value hierarchy in the current or previous year.

Accounting classifications and fair values
