Elmos reports encouraging sales growth in the second quarter of 2025

Sales in Q2 reach 145.7 million Euro – an increase of +14.8% versus the previous quarter and +2.6% versus the previous year – sales guidance 2025 confirmed despite negative exchange rate effects

"Thanks to our innovative product portfolio, we achieved significant double-digit growth in the second quarter. Our customers are increasingly returning to normal order levels and inventory adjustments are noticeably decreasing. Nevertheless, visibility remains low and the economic and geopolitical environment remains volatile. Earnings and cash flow in the second quarter were particularly influenced by the complex transformation to SAP S/4HANA. In addition, we are working with a strong focus to expand our local presence in China." Dr. Arne Schneider, CEO of Elmos Semiconductor SE

Further information on the key figures used can be found in the 2024 Annual Report at www.elmos.com.

Profit, financial position, as well as assets and liabilities

• -> Sales and earnings developed positively in the second quarter of 2025 in a continuing challenging environment, but remained impacted by customer inventory adjustments, exchange rate effects, and overall subdued market development outside China. In the first half of 2025, sales declined slightly compared with the previous year.
• -> Earnings before interest and taxes (EBIT) were also impacted by cost effects, including the SAP transformation, higher material costs and exchange rate effects.
• -> As expected, capital expenditures declined in the second quarter compared with the previous quarter. In the first six months of 2025, capital expenditures were significantly reduced compared with the previous year.
• -> Adjusted free cash flow in the second quarter of 2025 was influenced by higher working capital due to the SAP transformation.
• -> The ratio of orders received for the next three months (Q3 2025) to sales over the past three months (Q2 2025), known as the book-to-bill ratio, is currently just below one due to low visibility and short-term customer orders.

Sales by region

Economic environment

• -> In the first six months of fiscal year 2025, the economic environment was characterized by a slowdown in customer inventory adjustments, further escalating geopolitical tensions, increasing market momentum, particularly in China, and continued low visibility. Structurally, demand for semiconductors in the automotive sector remains robust due to increasing electrification, intelligent driver assistance systems, and growing connectivity and digitalization.
• -> The global automotive markets performed inconsistently in the first six months of 2025. According to S&P Global, China achieved growth of 11.7%, while America and Europe recorded declines of -2.4% and -3.3% respectively. Overall, global light vehicle production figures increased by 3.1%.
• -> In July 2025, the International Monetary Fund (IMF) slightly raised its forecast for global economic output for the current year by 0.2 percentage points to 3.0%. This is mainly due to lower average effective US tariff rates than announced in April, an improvement in financial conditions and fiscal expansion in some major jurisdictions. The biggest risks remain geopolitical tensions, disruptions in global supply chains, and increases in raw material prices. The growth forecast for China is 5.1%, for the US 1.9%, while the European economy is expected to grow by only 1.0%, with Germany at the bottom (0.1%).
• -> The prospects for the automotive semiconductor market remain positive. Demand for automotive semiconductors remains structurally high, and the growth trend remains intact as the number of intelligent electronic components in modern vehicles continues to rise.

Guidance Fiscal Year 2025

Sales	580 million Euro ± 30 million Euro
EBIT margin	23% ± 3% percentage points of sales
Capital expenditures1	7% ± 2% percentage points of sales
Adjusted free cash flow2	7% ± 2% percentage points of sales
Assumed average exchange rate	1.15 EUR/USD

1 Capital expenditures for intangible assets and property, plant and equipment, less capitalized development expenses. 2 Cash flow from operating activities less capital expenditures for/plus disposal of intangible assets and property, plant and equipment.

Explanation of the guidance for fiscal year 2025:

The full-year guidance reflects the current situation in the core markets relevant to the company and the continuing low level of visibility. The company is currently unable to predict the potential impact of the current customs issues on relevant markets or on the overall economic development. If trade relations deteriorate further, this could have a noticeable impact on performance in fiscal year 2025.

• -> The full-year guidance from February 2025 has been updated with regard to the exchange rate, and the underlying exchange rate has been adjusted from 1.05 EUR/USD to 1.15 EUR/USD. For the fiscal year 2025, Elmos still expects sales of 580 million Euro ± 30 million Euro despite an implied negative exchange rate effect of around 25 million Euro.
• -> The company continues to expect an EBIT margin of 23% ± 3 percentage points of sales, with the lower half of the guidance range currently appearing more likely, particularly due to one-time effects.
• -> Elmos continues to forecast capital expenditures for property, plant, and equipment and intangible assets less capitalized development expenses of around 7% ± 2 percentage points of sales.
• -> For fiscal year 2025, Elmos expects a positive adjusted free cash flow of 7% ± 2 percentage points of sales and thus significantly above the level of the prior year (2024: 0.9% of sales).

Opportunities and risks

• -> The individual company risks and opportunities are described in detail in our Annual Report 2024. With the exception of potential trade conflicts arising from US tariff policy, Elmos has not identified any material changes in the first half of fiscal year 2025 above and beyond the opportunities and risks presented in the Annual Report 2024.
• -> The tightening of US tariff policy following US Liberation Day and potential countertariffs by the countries affected could lead to market distortions or economic risks, so the probability of occurrence for this risk has been increased accordingly.
• -> The success of our products depends on general economic and political conditions and can be impacted by events such as economic crisis, military conflicts, political changes, geopolitical tension, and trade wars and trade restrictions.
• -> Elmos continuously monitors the geopolitical and economic environment in our core markets in order to anticipate new potential risks or changes in the assessment of risks as early as possible, and to be in a position to take action or make adjustments. However, it is not possible at the present time to completely assess the full extent of the risks posed by the current geopolitical and economic situation. Similarly, the company is currently unable to predict any potential impact on relevant markets or on overall economic development as a result of the current tariff issues, which could have a noticeable effect on performance in fiscal year 2025 if trade relations deteriorate further.
• -> In the first half of 2025, demand for automotive semiconductors continued to be affected by inventory adjustments, but our customers' inventory adjustments eased noticeably in the course of the second quarter. However, visibility remains low and customers continue to place orders at short notice. From today's perspective, it is therefore not possible to predict when customers' inventory adjustments will be fully completed.

-> As explained in the Annual Report, individual risks may cause substantial damage to the Company in extreme cases. Such cases can neither be predicted nor ruled out. Irrespective of this, it should be noted that the occurrence of an individual risk, even if it does not develop into an extreme case, can have a strong negative impact on the profit, financial position, as well as assets and liabilities of the Company.

Significant events

• -> Elmos held its Annual General Meeting as a virtual event on May 15, 2025. The shareholders adopted all of the items on the agenda by a large majority. The Annual General Meeting approved a roughly 17.6% dividend increase to 1.00 Euro per share for fiscal year 2024, which has already been distributed.

Notes to condensed interim consolidated financial statements January 1 to June 30

The condensed interim consolidated financial statements for the first half of 2025 were released for publication pursuant to Management Board resolution of July 31, 2025.

1 – GENERAL INFORMATION

The address of the Company's registered office is: Germany, 51379 Leverkusen, Werkstättenstraße 18. The registered office was relocated from Dortmund to Leverkusen by resolution of the Annual General Meeting on May 15, 2025.

Basic principles of the preparation of financial statements

The condensed interim consolidated financial statements for the period from January 1 to June 30, 2025 have been prepared in accordance with IAS 34, "Interim Financial Reporting." These financial statements therefore do not contain all the information and disclosures required for consolidated financial statements and should be consulted together with the consolidated financial statements for the fiscal year ended December 31, 2024.

Essential accounting policies and measurement methods

For the preparation of the condensed interim consolidated financial statements, the same accounting policies and measurement methods have been adopted as were applied for the preparation of the consolidated financial statements for the fiscal year ended December 31, 2024, with the exception of the amended IFRS standard explained below.

-> Amendments to IAS 21 – Effects of exchange rate changes: Lack of convertibility

The initial application of this amended standard did not have a material impact on the Group's financial, profit, and economic position.

Estimates and assumptions

The Company recognizes provisions for pension obligations pursuant to IAS 19. For 2025, an actuarial interest rate of 3.06% has been applied, unchanged from December 31, 2024. Provisions for pensions were not remeasured as of June 30, 2025, due to materiality reasons. They will be remeasured as of December 31, 2025. Due to the surplus of the asset values from reinsurance policies over the provisions for pension obligations, the balance is reported as an asset-side difference under other non-current financial assets.

Estimates and discretionary decisions

Estimates and discretionary decisions may have an impact on the amount of assets and liabilities reported in the balance sheet, the disclosures regarding contingent assets and liabilities as of the reporting date, and on the income and expenses disclosed for the reporting period. This is particularly true against the backdrop of ongoing geopolitical risks, especially Russia's war of aggression in Ukraine, the various armed conflicts in the Middle East, and the conflict surrounding Taiwan, which could result in price increases and shortages of energy and raw materials, exchange rate fluctuations, and disruptions to the supply chain. Rising inflation and higher interest rates could also lead to a significant decline in consumption. Customs disputes, as well as trade restrictions between leading industrial nations, could impair global trade, and thus economic development. As a result, the amounts actually incurred or accrued may differ from the estimates and discretionary decisions; changes may have a material effect on the interim financial statements. The available information on anticipated economic development was taken into account when updating the estimates and discretionary decisions. This information was taken into consideration when reviewing the impairment of financial assets.

Contracts with customers

The geographic segment "EU countries" basically includes all member states of the European Union at the current reporting date. The European countries that are not currently members of the European Union are part of the "Other" segment. Revenue from external customers is distributed according to the customer's delivery locations.

Exceptional business transactions

There were no exceptional business transactions in the first six months of 2025.

Scope of consolidation

Online Engineering GmbH, Dortmund, was merged into the group company Elmos Semiconductor Sales & Solutions GmbH, Dortmund, with effect from January 1, 2025.

Mechaless GmbH, Bruchsal, was merged into the parent company Elmos Semiconductor SE, Leverkusen, with effect from January 1, 2025.

The mergers did not have any impact on earnings within the scope of consolidation.

Seasonal and economic effects on business operations

Based on the latest economic outlook by the International Monetary Fund (IMF) from July 2025, there are no significant changes to the outlook for the future business development.

2 – INFORMATION ON FINANCIAL INSTRUMENTS

The following table lists the book values and fair values of the Group's financial instruments. The fair value of a financial instrument is the price that would be received for the sale of an asset or paid for the transfer of a liability between market participants in a regular business transaction as of the reporting date. In view of varying factors of influence, the presented fair values can only be regarded as indicators of the amounts actually recoverable in the market. Detailed information on the methods and assumptions underlying the determination of the value of financial instruments can be found under note 29 to the 2024 consolidated financial statements. Its relevance to these half-year financial statements is undiminished.

REVIEW REPORT

To Elmos Semiconductor SE, Leverkusen

We have reviewed the condensed interim consolidated financial statements − comprising the consolidated balance sheet, consolidated income statement, consolidated statement of comprehensive income, consolidated cash flow statement, changes in consolidated equity and selected selected notes to the consolidated financial statements − and the interim group management report of Elmos Semiconductor SE, Leverkusen, for the period from 1 January 2025 to 30 June 2025, which are components of the half-year financial report pursuant to Section 115 of the German Securities Trading Act (WpHG), and have issued this audit opinion. The preparation of the condensed interim consolidated financial statements in accordance with IFRS for interim financial reporting as applicable in the EU and the interim group management report in accordance with the provisions of the WpHG applicable to interim group management reports is the responsibility of the company's legal representatives. Our responsibility is to issue a certificate on the condensed interim consolidated financial statements and the interim group management report based on our review.

We conducted our review of the condensed interim consolidated financial statements and the interim group management report in accordance with the German generally accepted standards for the review of financial statements promulgated by the Institut der Wirtschaftsprüfer (IDW). Those standards require that we plan and perform the review so that we can preclude through critical evaluation, with a certain level of assurance, that the condensed interim consolidated financial statements have not been prepared, in material aspects, in accordance with the IFRS applicable to interim financial reporting as adopted by the EU, and that the interim group management report has not been prepared, in material aspects, in accordance with the regulations of the German Securities Trading Act applicable to interim group management reports. A review is limited primarily to inquiries of Company employees and analytical assessments and therefore does not provide the assurance attainable in a financial statement audit. Since, in accordance with our engagement, we have not performed a financial statements audit, we cannot issue an auditor's report.

Based on our review no matters have come to our attention that cause us to believe that the condensed interim consolidated financial statements have not been prepared, in material respects, in accordance with the IFRS applicable to interim financial reporting as adopted by the EU, or that the interim group management report has not been prepared, in material respects, in accordance with the regulations of the German Securities Trading Act applicable to interim group management reports.

Forward-looking statements

This report contains statements directed to the future that are based on assumptions and estimates made by the management of Elmos. Even though we assume the underlying expectations of our forward-looking statements to be realistic, we cannot guarantee these expectations will prove right. The assumptions may carry risks and uncertainties, and as a result actual events may differ materially from the current statements made with respect to the future. Among the factors that could cause material differences are changes in general economic and business conditions, changes in exchange and interest rates, the introduction of competing products, lack of acceptance of new products, and changes in business strategy. Elmos neither intends nor assumes any obligation to update its statements with respect to future events.
