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, 2024.

Highlights

In the first half of 2025, total revenue amounted to USD 419,396 thousand (first half of 2024: USD 421,254 thousand), a slight decrease of 0.44% compared to the same period in the previous year.

Revenue in X-FAB's core business, namely automotive, industrial, and medical, came in at USD 394,275 thousand (first half of 2024: USD 392,675 thousand), an increase of 0.4% compared to the same period in the previous year. X-FAB's core business generated 93.7% of total revenue (first half of 2024: 93.1%).

Business in the first half of 2025 progressed more favorably than anticipated with strong sequential growth in bookings in the first and second quarter of 2025, pointing to a gradual recovery across all end markets and technologies.

Among the growth drivers were EV-related automotive applications, power management applications for data centers, and medical-grade contactless temperature sensors. X-FAB's industrial business benefited from increased demand following the last-time-buy announcement for some of X-FAB's 150mm CMOS technologies, as well as from revenue generated by prototyping new customer projects.

The end of the second quarter also marks the completion of X-FAB's three-year program to expand manufacturing capacities across the Group. The main focus in the first half of the year was on equipping the new clean room in Kuching, Malaysia. The expansion of capacity for X-FAB's popular 180nm CMOS processes provides sufficient capacity to serve current and future customer demand, which is key to supporting X-FAB's CMOS and microsystems business going forward.

Revenue analysis

*excluding revenues from wafer sales recognized over time

Business fundamentals are intact and X-FAB remains well positioned for long-term business success. X-FAB 's comprehensive and highly specialized technology portfolio enables innovative solutions to address the major megatrends of our time. The electrification of everything is inevitable in order to move away from fossil fuels and mitigate climate change, driving long-term growth in X-FAB's automotive and industrial businesses. Aging and growing populations require technological innovation to make prevention, diagnosis and treatment of disease more efficient, reliable and accessible to an ever-growing number of people. X-FAB's microsystems expertise with the combination of CMOS and MEMS supports the development of world-leading medical applications and fuels the long-term growth of X-FAB's medical business.

Cost of sales

Cost of sales includes material expenses such as raw materials, the costs of maintaining fixed assets, depreciation, staff costs, and costs for external services. In 2025 cost of sales decreased by USD 1,196 thousand or 0.4% compared to the first half of 2024, in line with the slight decrease in revenue.

Research and development expenses

Research and development expenses amounted to USD 24,450 thousand in the first half of 2025, representing 5.8% of revenue (first half of 2024: USD 22,494 thousand, 5.3% of revenue). The increase of 8.7% (USD 1,956 thousand) compared to the previous year's comparable six-month period is due to higher staff and mask costs. Research and development expenses are presented net of grants in the amount of USD 3,104 thousand, (first half of 2024: USD 2,503 thousand). The Group's research and development activities focus on the development of new fabrication processes, the optimization of existing processes using the Group's key process technologies, and the development of new integrated circuit features in order to meet customers' analog/mixed signal needs.

General, administrative, and selling expenses

General and administrative expenses and selling expenses remain on the same level compared to the first half of 2024.

Net finance costs

Net finance costs increased by USD 35,607 thousand in the first half of 2025 compared to the first half of previous year due to increased unrealized exchange rate losses on euro-denominated loans and borrowings (USD 30,876 thousand).

Net income

The Group recorded a profit for the period for the first half of 2025 of USD 11,810 thousand, compared to a profit of USD 42,880 thousand in the first half of 2024.

The announcement of third quarter results will take place on October 30, 2025.

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:

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 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's registered address is Transportstraat 1, 3980 Tessenderlo-Ham, Belgium.

The X-FAB SE Group is one of the world's leading pure-play foundry providers specializing in analog/mixedsignal technologies. Analog/mixed-signal products are circuits capable of processing digital as well as analog signals. 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. For this purpose, X-FAB SE offers special technology modules, cell libraries, and design kits, which allow the Group's customers to develop specific circuits with broad function spectrums and to accelerate their development processes.

X-FAB SE Group's customers include companies that concentrate on the development of integrated circuits (ICs) and leave their manufacture to others (fabless companies). The Group's customers are primarily in the communication, automotive, consumer, and industrial product sectors, and are located in Europe, the United States, and Asia.

2.5.2 Acquisition of a subsidiary

On January 1, 2024, the Group acquired the entire share capital of M-MOS Semiconductor Hong Kong Limited (M-MOS), a limited liability company incorporated under the laws of Hong Kong, and its subsidiaries for a consideration of EUR 22,500 thousand (USD 24,863 thousand) payable in cash. M-MOS was acquired from XTRION, a related party.

M-MOS is a developer of metal–oxide–semiconductor field-effect transistor (MOSFET) process technologies and designs standard and custom devices using MOSFET technologies focusing on selling wafers to its customers. The acquisition was made to generate business synergies in particular in respect of the MOSFET wafer business.

No acquisition costs were recorded as expenses in the current or previous financial year in respect of the acquisition.

The fair values of the assets and liabilities determined as at January 1, 2024 exceeded the carrying values recorded by the acquiree by USD 73 thousand and were as follows:

in thousands of U.S. dollars
Property, plant, and equipment	238
Deferred tax assets	66
Inventories	2,878
Accounts receivable	4,483
Other assets	4,532
Cash and cash equivalents	23,229
Total assets	35,426
Non-current loans and borrowings	26
Trade payables	2,691
Other current liabilities	7,712
Deferred tax liabilities	134
Total liabilities	10,563
Total identifiable assets and liabilities acquired	24,863

The above amounts represent the Group's estimates of the fair values of the assets and liabilities assumed at the acquisition date. No material differences between the carrying amounts and fair market values of the assets and liabilities acquired were identified due to the fact that the assets acquired primarily consisted of cash and cash equivalents and in view of the short-term nature of the receivables and liabilities. No goodwill was recognized as a result of the business combination.

M-MOS contributed revenues of USD 9,395 thousand and a profit of USD 1,287 thousand) to the Group results in the first half of the financial year 2025 (first half of the financial year 2024: revenues of USD 8,796 thousand and a profit of USD 1,152 thousand).

2.5.3 Basis of preparation

Statement of compliance

These condensed consolidated interim 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 notinclude all ofthe information required forfull annual financial statements and should be read in conjunction with the Group's last annual consolidated financial statements as at and forthe year ended December 31, 2024.

The condensed consolidated interim financial statements of X-FAB SE Group were authorized for issue in accordance with a resolution ofthe directors on August 28, 2025.

Use of estimates and judgements

In preparing these condensed consolidated interim financial statements, management has made judgments, 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 judgments 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, 2024.

Measurement of fair values

A number of the Group's accounting policies and disclosures require the measurement of fair values, for both 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.

2.5.4 Summary of material accounting policies

The accounting policies applied are consistent with those applied in the annual consolidated financial statements ended December 31, 2024.

2.5.5 New accounting pronouncements

Amendments to standards effective for the period beginning on January 1, 2025

The following amendments to IFRS standards, which are effective for annual periods beginning on or before January 1, 2025, have been applied by the Group for the first time in preparing these condensed consolidated interim financial statements.

2.5.6 Notes

2.5.6.1 Revenue

Revenue comprises the following:

in thousands of U.S. dollars	For the six months ended June 30
	2025	2024
Gross revenue PCM wafer	390,273	378,274
Gross revenue NRE and technology services	39,608	46,532
Impact from PCM wafer revenue recognized over time	(1,211)	(305)
Other revenue	3	6
Discounts and warranty credits	(9,277)	(3,253)
Total	419,396	421,254

In the first half of 2025 there was a downward adjustment of USD 1,211 thousand to report recognized for sales made in 2025 based on the recognition over time basis in accordance with IFRS 15 compared to the amounts recognized based on the date the wafers were delivered. In contrast, in the same period of the previous year the adjustment of revenue recognition to reflect the sale of PCM wafers over time resulted in a decrease in revenues recognized of USD 0.3 million. The Group reports revenues from wafer sales which are recognized over time in compliance with IFRS 15 Revenue from Contracts with Customers. For transparency purposes, the Group also reports revenue from PCM wafer sales based on recognizing the associated revenues at the specific point in time when the wafers are delivered to the customer as well as the amount of the reconciling item between the revenue recognized on the over time basis and the revenue recognized on the basis of the delivery of the wafers. Revenue for wafer sales recognized over time represents the Group's rights to consideration for work completed but not invoiced at the reporting date on wafer sales under long-term contracts which meet the criteria for revenue recognition over time.

The Group has recognized no revenues of variable consideration from customers in respect of shortfalls of orders from customers in the first half of the financial year 2025 (2024: none) as, at the current time, it is anticipated that all customer orders will be supplied to customers in full without any shortfalls.

Revenue from NRE and technology services is recognized over time, based on milestones that are a reasonable approximation of the progress to complete the performance obligation.

Total	(956)	(1,584)

2.5.6.3 Finance income

Finance income comprises the following:

in thousands of U.S. dollars	For the six months ended June 30
	2025	2024
Interest on financial assets measured at amortized cost:
Interest on cash and cash equivalents	2,186	6,473
Change in fair value of financial assets and liabilities at fair value through profit or loss:
Change in fair value of derivative financial instruments	4,160	-
Other:
Income from exchange rate differences	19,760	6,080
Total	26,106	12,553

Income from exchange rate differences includes unrealized exchange rate gains (net of expenses) of USD 974 thousand (2024 loss of: USD 4,272 thousand) resulting from the translation of cash balances denominated in Malaysian ringgit and of USD 7,131 thousand (2024: USD 3,421 thousand) from cash balances denominated in euros.

2.5.6.4 Finance costs

Finance costs comprise the following:

in thousands of U.S. dollars	For the six months ended June 30
	2025	2024
Interest on financial liabilities measured at amortized cost:
Loans and borrowings	(9,850)	(6,494)
Other interest	(407)	(632)
Other :
Expenses from exchange rate differences	(40,421)	(7,946)
Total	(50,678)	(15,072)

Exchange rate expenses include realized and unrealized exchange rate losses of USD 30,876 thousand (2024: income of USD 4,272 thousand) on euro-denominated loans and borrowings.

2.5.6.5 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
	2025	2024
Current taxes:
Actual income tax charge for the period	(4,025)	(3,658)
Adjustment of prior years' tax charges	(16)	(304)
	(4,041)	(3,962)
Deferred taxes	(2,381)	(657)
Total	(6,422)	(4,619)

Changes in recognized deferred tax assets resulted in a decrease of deferred tax assets of USD 2,345 thousand (2024: a decrease of USD 599 thousand). The decrease in deferred tax assets is primarily due to the derecognition of previously recognized deferred tax assets on timing differences arising on property, plant, and equipment of X-FAB Sarawak amounting to USD 2,586 thousand (2024: derecognition of USD 594 thousand) to reflect the current estimate of realizable deferred taxes on reversals of timing differences based on the Group's updated business planning.

The assumptions made and the method applied to calculate deferred taxes were consistent with the methods used at December 31, 2024. 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.

Belgium, the jurisdiction where the "ultimate parent entity" (i.e. X-FAB Silicon Foundries SE) of the X-FAB group is located, formally adopted the Pillar Two (Global Minimum Tax) legislation in December 2023, effective from 2024 onwards (i.e. for financial years starting on or after December 31, 2023). Up to and including the financial year starting on January 1, 2025, the X-FAB Group did not yet meet the criteria to be subject to the Pillar Two legislation. However, as from the financial year starting on January 1, 2026, the X-FAB Group expects to fall within the scope of this legislation. The X-FAB Group has applied a temporary mandatory relief from deferred tax accounting for the impacts of the top-up tax (if any) and will account for such top-up tax as a current tax when it is incurred.

2.5.6.6 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.

2.5.6.7 Property, plant, and equipment

Assets under construction contain purchases of technical machinery and equipment in all X-FAB sites as a result of its group-wide capacity expansion program. This three-year program was completed in the second quarter of 2025.

In the first half of 2025, the Group received USD 0 thousand investment tax credits within the U.S. related to the acquisition of qualifying assets (2024: USD 10,195 thousand). The acquisition costs of technical equipment have been reduced accordingly.

The carrying values of right-of-use assets presented as property, plant and equipment were as follows:

in thousands of U.S. dollars	2025	2024
Net book value January 1	39,323	17,588
Additions	337	1,027
Depreciation	(2,486)	(3,690)
Reclassifications	13	18,210
Effects of changes in currency exchange rates	-	26
Net book value Dec 31	37,187	33,161

In 2025,the Group entered into a sale and leaseback transaction under which machinery was sold at book value and leased back. The contractual arrangements include a purchase option to buy the underlying asset at a price thatis expected to be sufficiently lowerthan the expected fair value ofthe underlying asset on the date at which the option becomes exercisable. The Group continues to be able to directthe use ofthe assets and obtain substantially all ofthe remaining benefits from their use. Accordingly,the transaction was wholly recognized as a financing arrangement and no sale or gain or loss is recognized on the transaction. A similar sale and leaseback transaction with a net book value of USD 17,830,000 that was entered into in 2024 was excluded from the beginning balance as of January 1, 2025.

2.5.6.8 Inventories

The increase in raw materials and supplies and work in progress resulted from the build-up ofinventories to secure the material supplies required to meet anticipated higher outputlevels resulting from the overall increase in business activity. Inventories forthe manufacture of wafers under contracts for which sales are recognized overtime are notrecognized in work in process; instead they are recorded as an expense within cost of sales with the associated rights to consideration for work completed but notinvoiced atthe reporting date recognized within contract assets (note 2.5.6.9 below).

Allowances of USD 602 thousand (2024: USD 55 thousand) have been recorded againstinventories and recognized as an expense in the period.

2.5.6.9 Contract assets

The contract assets relate to the Group's rights to consideration for work completed but not invoiced at the reporting date on wafer sales recognized over time. No impairment charges have been recognized on contract assets. The contract assets are transferred to receivables when the rights become unconditional. This usually occurs when the Group issues an invoice to the customer.

2.5.6.10 Other assets

Other assets comprise the following:

in thousands of U.S. dollars	June 30, 2025	December 31, 2024
R&D grants receivable	35,287	26,795
Prepaid expenses	16,197	17,538
Investment grants and subsidies receivable	9,844	9,890
Derivatives	4,160	-
Receivables from energy surcharges	2,781	5,706
Taxes (other)	2,381	6,337
Deposits	565	483
Other	808	674
Total	72,023	67,423

Prepaid expenses primarily relate to prepayments made for raw materials such as raw wafers.

Research and development grants receivable at June 30, 2025 include research and development tax credits and competitiveness and employment tax credits totaling USD 18,430 thousand attributable to X-FAB France (December 31, 2024: USD 13,440 thousand).

Derivatives presented within other assets represent the fair value of two currency forward contracts (derivatives) which provide for the sale, in exchange for euros, of USD 60 million at December 31, 2025 which correspond to the amounts of loan repayments payable in euros at December 31, 2025. There was no acquisition cost associated with these instruments. The changes in the fair value of these currency forward contracts are intended to offset the currency gains or losses on exchange associated with those euro denominated loan repayments. The Group does not apply hedge accounting. Accordingly, the change in fair value of the derivatives is presented in the consolidated statement of profit and loss as finance income (2025: USD 4,160 thousand; 2024: USD 0 thousand).

Other taxes primarily relate to VAT receivables.

2.5.6.11 Cash and cash equivalents

Cash and cash equivalents comprise the following:

Both credit facilities are for a five-year period until December 2026 and July 2029 respectively, with an option for X-FAB to request an extension of the facility's maturity date for a further year until December 2027 and July 2030 respectively. The options are exercisable not earlier than 90 days prior to and not 45 days later than prior to the respective initial termination dates.

The movement in loans and borrowings includes income for realized and unrealized exchange rate losses of USD 30,876 thousand (2024: gains of USD 4,272 thousand) resulting from the effect of changes on exchange rates of euro-denominated loans. Loans and lease obligations totaling USD 51,828 thousand (2024: USD 103,987 thousand) have been repaid in the first six months of 2025.

2.5.6.15 Other liabilities

Other current liabilities comprise the following:

in thousands of U.S. dollars	June 30, 2025	December 31, 2024

These amounts represent contract liabilities as defined in IFRS 15 and, depending on the respective agreements with the customer, will be settled by offsetting advances received against deliveries of wafers made or by repayment of the respective capacity reservation deposit periods.

All prepayments from customers for future wafer sales and capacity reservation deposits are recorded as current or non-current based on the usual classification principles, i.e., items that are settled within the normal operating cycle are classified as current, even if they are expected to be settled after twelve months. However, the Group expects prepayments from customers for future wafer sales and capacity reservation deposits totaling USD 177,392 thousand to be settled after more than twelve months (December 31, 2024: USD 225,311 thousand).

2.5.6.16 Notes to the statement of cash flows

Cash flows from operating activities in the first half of the financial year 2025 and 2024 include significant amounts of receipts of prepayments from customers for the future supply of wafers and receipts and repayments of capacity reservation deposits received under long-term agreements concluded with customers. The amounts of prepayments from customers and capacity reservation deposits carried forward for offsetting against trade accounts receivable or for repayment to customers are disclosed within other current liabilities as reported in note 2.5.6.15.

Non-cash transactions include currency effects from exchange rate differences of USD 20,661 thousand (2024:1,866 thousand) and increases in provisions of USD 2,303 thousand (2024: USD 4,039 thousand).

2.5.6.18 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 atfair 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

As described in 2.5.6.10, the Group has entered into two currency forward contracts (derivatives) which provide for the sale, in exchange for euros, of USD 60 million at December 31, 2025 which correspond to the amounts of two loan repayments payable in euros at December 31, 2025. There was no acquisition cost associated with these instruments. The changes in the fair value of these currency forward contracts, are intended to offset the currency gains or losses on exchange associated with those euro denominated loan repayments. The fair value of the derivatives is presented in the consolidated statement of profit and loss as finance income (2025: USD 4,160 thousand; 2024: USD 0 thousand). The fair values of the foreign currency forward contracts are determined by reference to the forward rates of the respective currency amounts over the life of the contract, discounted to the present value.

The Group held no financial instruments measured at fair value in the previous financial year and did not make use of forward foreign exchange or interest rate swaps in the current or previous 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

The following table shows the carrying amounts and fair values of financial assets and financial liabilities, including their levels in the fair value hierarchy. It does not include fair value information for financial assets and financial liabilities not measured at fair value if the carrying amount is a reasonable approximation of fair value.
