Report on the Audit of the Consolidated Financial Statements and of the Group Management Report

Opinions

We have audited the consolidated financial statements of Wacker Chemie AG, München and its subsidiaries (the Group), which comprise the consolidated statement of financial position as at December 31, 2023, and the consolidated statement of comprehensive income, consolidated statement of changes in equity and consolidated statement of cash flows for the financial year from January 1, 2023 to December 31, 2023, and notes to the consolidated financial statements, including a summary of significant accounting policies. In addition, we have audited the group management report of Wacker Chemie AG for the financial year from January 1, 2023 to December 31, 2023. In accordance with German legal requirements we have not audited the content of those components of the group management report specified in the “Other Information” section of our auditor’s report.

In our opinion, on the basis of the knowledge obtained in the audit,

  • the accompanying consolidated financial statements comply, in all material respects, with the IFRSs as adopted by the EU, and the additional requirements of German commercial law pursuant to Section 315e (1) HGB [Handelsgesetzbuch: German Commercial Code] and, in compliance with these requirements, give a true and fair view of the assets, liabilities, and financial position of the Group as at December 31, 2023, and of its financial performance for the financial year from January 1, 2023 to December 31, 2023, and
  • the accompanying group management report as a whole provides an appropriate view of the Group’s position. In all material respects, this group management report is consistent with the consolidated financial statements, complies with German legal requirements and appropriately presents the opportunities and risks of future development. Our opinion on the group management report does not cover the content of those components of the group management report specified in the “Other Information” section of the auditor´s report. 

Pursuant to Section 322 (3) sentence 1 HGB, we declare that our audit has not led to any reservations relating to the legal compliance of the consolidated financial statements and of the group management report. 

Basis for the Opinions

We conducted our audit of the consolidated financial statements and of the group management report in accordance with Section 317 HGB and the EU Audit Regulation No. 537/2014 (referred to subsequently as “EU Audit Regulation”) and in compliance with German Generally Accepted Standards for Financial Statement Audits promulgated by the Institut der Wirtschaftsprüfer [Institute of Public Auditors in Germany] (IDW). Our responsibilities under those requirements and principles are further described in the “Auditor’s Responsibilities for the Audit of the Consolidated Financial Statements and of the Group Management Report” section of our auditor’s report. We are independent of the group entities in accordance with the requirements of European law and German commercial and professional law, and we have fulfilled our other German professional responsibilities in accordance with these requirements. In addition, in accordance with Article 10 (2) point (f) of the EU Audit Regulation, we declare that we have not provided non-audit services prohibited under Article 5 (1) of the EU Audit Regulation. We believe that the evidence we have obtained is sufficient and appropriate to provide a basis for our opinions on the consolidated financial statements and on the group management report. 

Key Audit Matters in the Audit of the Consolidated Financial Statements 

Key audit matters are those matters that, in our professional judgment, were of most significance in our audit of the consolidated financial statements for the financial year from January 1, 2023 to December 31, 2023. These matters were addressed in the context of our audit of the consolidated financial statements as a whole, and in forming our opinion thereon, we do not provide a separate opinion on these matters. 

Valuation of property, plant and equipment in the WACKER POLYSILICON segment

For information on the WACKER POLYSILICON segment in the fiscal year, please refer to the "Segment Data by Division" section in the consolidated financial statements and the "Segment Reporting" section in the combined management report. For information on the accounting policies applied, please refer to the "Accounting Estimates and Assumptions" and "Accounting and Valuation Principles" sections in the notes to the consolidated financial statements. With regard to sales market risks, please refer to the "Risk report" section in the combined management report.

The Risk for the Financial Statements

The carrying amount of assets in the WACKER POLYSILICON segment amounted to EUR 981.3 million as at the reporting date. In the 2019 fiscal year, an impairment loss of EUR 760 million was recognized for the segment's property, plant and equipment. In addition to scheduled depreciation and amortization, no further impairment losses or write-ups have been recognized since then or in the 2023 fiscal year. The photovoltaic market, which is important for the segment, is characterized by high volatility and intense competition. As a result, business development in the WACKER POLYSILICON segment has been characterized by strong price fluctuations in the past. Sales in the WACKER POLYSILICON segment fell by 30% in the fiscal year, and the EBITDA margin declined significantly compared with the previous year. The main reasons for this development were lower prices and sales volumes in the solar-silicon segment and high energy prices.

Despite this negative development, the risk of significant overcapacity in the market and the associated further high price volatility is expected to continue in the future. Production facilities in Burghausen, Nünchritz and Charleston, which together form a cash-generating unit, are allocated to this segment.

Impairment tests must be carried out for property, plant and equipment if there are indications of possible impairment. Furthermore, an entity must assess at each reporting date whether there is any indication that an impairment loss recognized for an asset in prior periods may no longer exist or may have decreased. If such an indication exists or ceases to exist, the recoverable amount of the cash-generating unit's assets is to be estimated, which corresponds to the higher of fair value less costs to sell and value in use.

Operational planning, and thus the assessment of whether the WACKER POLYSILICON segment's property, plant and equipment is appropriately valued, involves judgment and requires assumptions about the discount rate and numerous forward-looking estimates - e.g. the future demand based on the expected expansion of photovoltaic systems and the development of the semiconductor market, which are the main sales markets for polysilicon, price trends, the global expansion of polysilicon production capacities and the resulting expected cash inflows and outflows. Against this backdrop, there is a risk for the consolidated financial statements that the property, plant and equipment reported by the WACKER POLYSILICON segment as of the reporting date has not been recognized in an appropriate amount.

Our Approach to the Audit

We obtained an understanding of the Company's process for identifying indications of impairment and reversals of impairment and determining the recoverable amounts through explanations provided by Corporate Accounting employees. We analyzed the indications of impairment identified by the Company and assessed them on the basis of the information obtained during our audit. We obtained the impairment test prepared by the Company for the WACKER POLYSILICON segment. In discussions with, among others, the Executive Board, representatives of the WACKER POLYSILICON segment and the Corporate Accounting department, we obtained an explanation of the valuation assumptions and parameters used and an understanding of the planning process. With the involvement of our valuation specialists, we assessed the valuation assumptions and parameters as well as the mathematical accuracy and IFRS conformity of the Company's valuation model. Furthermore, we assessed the appropriateness of the assumptions and parameters underlying the expected cash inflows and outflows by comparing them with the corporate planning approved by the Supervisory Board and by comparing them with general and industry-specific market expectations. The latter are based in particular on long-term external forecasts regarding the installation volume in the photovoltaic sector and the development of the semiconductor market.

Our Conclusions

The assumptions and parameters used by the company to assess the valuation of property, plant and equipment in the WACKER POLYSILICON segment and the conclusions drawn from the impairment test based on these are appropriate.

Other Information

Management respectively supervisory board are responsible for the other information. The other information comprises the following components of the group management report, whose content was not audited:

  • the group non-financial statement of the group management report, 
  • the group corporate governance statement, included in section Governance of the group management report, and
  • information extraneous to management reports and marked as unaudited.

The other information includes also the remaining parts of the annual report.

The other information does not include the consolidated financial statements, the group management report information audited for content and our auditor’s report thereon.

Our opinions on the consolidated financial statements and on the group management report do not cover the other information, and consequently we do not express an opinion or any other form of assurance conclusion thereon.

In connection with our audit, our responsibility is to read the above-mentioned other information and, in so doing, to consider whether the other information 

  • is materially inconsistent with the consolidated financial statements, with the group management report information audited for content or our knowledge obtained in the audit, or
  • otherwise appears to be materially misstated. 

Responsibilities of Management and the Supervisory Board for the Consolidated Financial Statements and the Group Management Report

Management is responsible for the preparation of the consolidated financial statements that comply, in all material respects, with IFRSs as adopted by the EU and the additional requirements of German commercial law pursuant to Section 315e (1) HGB and that the consolidated financial statements, in compliance with these requirements, give a true and fair view of the assets, liabilities, financial position, and financial performance of the Group. In addition, management is responsible for such internal control as they have determined necessary to enable the preparation of consolidated financial statements that are free from material misstatement, whether due to fraud (i.e., fraudulent financial reporting and misappropriation of assets) or error. 

In preparing the consolidated financial statements, management is responsible for assessing the Group’s ability to continue as a going concern. They also have the responsibility for disclosing, as applicable, matters related to going concern. In addition, they are responsible for financial reporting based on the going concern basis of accounting unless there is an intention to liquidate the Group or to cease operations, or there is no realistic alternative but to do so.

Furthermore, management is responsible for the preparation of the group management report that, as a whole, provides an appropriate view of the Group’s position and is, in all material respects, consistent with the consolidated financial statements, complies with German legal requirements, and appropriately presents the opportunities and risks of future development. In addition, management is responsible for such arrangements and measures (systems) as they have considered necessary to enable the preparation of a group management report that is in accordance with the applicable German legal requirements, and to be able to provide sufficient appropriate evidence for the assertions in the group management report. 

The supervisory board is responsible for overseeing the Group’s financial reporting process for the preparation of the consolidated financial statements and of the group management report.

Auditor’s Responsibilities for the Audit of the Consolidated Financial Statements and of the Group Management Report 

Our objectives are to obtain reasonable assurance about whether the consolidated financial statements as a whole are free from material misstatement, whether due to fraud or error, and whether the group management report as a whole provides an appropriate view of the Group’s position and, in all material respects, is consistent with the consolidated financial statements and the knowledge obtained in the audit, complies with the German legal requirements and appropriately presents the opportunities and risks of future development, as well as to issue an auditor’s report that includes our opinions on the consolidated financial statements and on the group management report.

Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with Section 317 HGB and the EU Audit Regulation and in compliance with German Generally Accepted Standards for Financial Statement Audits promulgated by the Institut der Wirtschaftsprüfer (IDW) will always detect a material misstatement. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these consolidated financial statements and this group management report.

We exercise professional judgment and maintain professional skepticism throughout the audit. We also: 

  • Identify and assess the risks of material misstatement of the consolidated financial statements and of the group management report, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinions. The risk of not detecting a material misstatement resulting from fraud is higher than the risk of not detecting a material misstatement resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control.
  • Obtain an understanding of internal control relevant to the audit of the consolidated financial statements and of arrangements and measures (systems) relevant to the audit of the group management report in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of these systems. 
  • Evaluate the appropriateness of accounting policies used by management and the reasonableness of estimates made by management and related disclosures. 
  • Conclude on the appropriateness of management’s use of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Group’s ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in the auditor’s report to the related disclosures in the consolidated financial statements and in the group management report or, if such disclosures are inadequate, to modify our respective opinions. Our conclusions are based on the audit evidence obtained up to the date of our auditor’s report. However, future events or conditions may cause the Group to cease to be able to continue as a going concern.  
  • Evaluate the overall presentation, structure and content of the consolidated financial statements, including the disclosures, and whether the consolidated financial statements present the underlying transactions and events in a manner that the consolidated financial statements give a true and fair view of the assets, liabilities, financial position and financial performance of the Group in compliance with IFRSs as adopted by the EU and the additional requirements of German commercial law pursuant to Section 315e (1) HGB.  
  • Obtain sufficient appropriate audit evidence regarding the financial information of the entities or business activities within the Group to express opinions on the consolidated financial statements and on the group management report. We are responsible for the direction, supervision and performance of the group audit. We remain solely responsible for our opinions.  
  • Evaluate the consistency of the group management report with the consolidated financial statements, its conformity with [German] law, and the view of the Group’s position it provides.
  • Perform audit procedures on the prospective information presented by management in the group management report. On the basis of sufficient appropriate audit evidence we evaluate, in particular, the significant assumptions used by management as a basis for the prospective information, and evaluate the proper derivation of the prospective information from these assumptions. We do not express a separate opinion on the prospective information and on the assumptions used as a basis. There is a substantial unavoidable risk that future events will differ materially from the prospective information.

We communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal control that we identify during our audit.

We also provide those charged with governance with a statement that we have complied with the relevant independence requirements, and communicate with them all relationships and other matters that may reasonably be thought to bear on our independence, and where applicable, the actions taken or safeguards applied to eliminate independence threats.

From the matters communicated with those charged with governance, we determine those matters that were of most significance in the audit of the consolidated financial statements of the current period and are therefore the key audit matters. We describe these matters in our auditor’s report unless law or regulation precludes public disclosure about the matter.

Other Legal and Regulatory Requirements 

Report on the Assurance on the Electronic Rendering of the Consolidated Financial Statements and the Group Management Report Prepared for Publication Purposes in Accordance with Section 317 (3a) HGB

We have performed assurance work in accordance with Section 317 (3a) HGB to obtain reasonable assurance about whether the rendering of the consolidated financial statements and the group management report (hereinafter the “ESEF documents”) contained in the electronic file „wackerchemieag-2023-12-31-de1.zip“ (SHA256-Hashwert: 9f2de3e2e080fa8ba06513bc7f863f72e20816458755164809fd1384921bbde2) made available and prepared for publication purposes complies in all material respects with the requirements of Section 328 (1) HGB for the electronic reporting format (“ESEF format”). In accordance with German legal requirements, this assurance work extends only to the conversion of the information contained in the consolidated financial statements and the group management report into the ESEF format and therefore relates neither to the information contained in these renderings nor to any other information contained in the file identified above.

In our opinion, the rendering of the consolidated financial statements and the group management report contained in the electronic file made available, identified above and prepared for publication purposes complies in all material respects with the requirements of Section 328 (1) HGB for the electronic reporting format.

Our responsibility in accordance therewith is further described below. Our audit firm applies the IDW Standard on Quality Management 1: Requirements for Quality Management in Audit Firms (IDW QS 1).

The Company’s management is responsible for the preparation of the ESEF documents including the electronic rendering of the consolidated financial statements and the group management report in accordance with Section 328 (1) sentence 4 item 1 HGB and for the tagging of the consolidated financial statements in accordance with Section 328 (1) sentence 4 item 2 HGB.

In addition, the company’s management is responsible for such internal control that they have considered necessary to enable the preparation of ESEF documents that are free from material intentional or unintentional non-compliance with the requirements of Section 328 (1) HGB for the electronic reporting format.

The supervisory board is responsible for overseeing the process of preparing the ESEF documents as part of the financial reporting process.

Our objective is to obtain reasonable assurance about whether the ESEF documents are free from material intentional or unintentional non-compliance with the requirements of Section 328 (1) HGB. We exercise professional judgement and maintain professional scepticism throughout the assurance work. We also:

  • Identify and assess the risks of material intentional or unintentional non-compliance with the requirements of Section 328 (1) HGB, design and perform assurance procedures responsive to those risks, and obtain assurance evidence that is sufficient and appropriate to provide a basis for our assurance opinion.
  • Obtain an understanding of internal control relevant to the assurance on the ESEF documents in order to design assurance procedures that are appropriate in the circumstances, but not for the purpose of expressing an assurance opinion on the effectiveness of these controls.
  • Evaluate the technical validity of the ESEF documents, i.e. whether the file made available containing the ESEF documents meets the requirements of the Delegated Regulation (EU) 2019/815, as amended as at the reporting date, on the technical specification for this electronic file.
  • Evaluate whether the ESEF documents provide an XHTML rendering with content equivalent to the audited consolidated financial statements and the audited group management report.
  • Evaluate whether the tagging of the ESEF documents with Inline XBRL technology (iXBRL) in accordance with the requirements of Articles 4 and 6 of the Delegated Regulation (EU) 2019/815, as amended as at the reporting date, enables an appropriate and complete machine-readable XBRL copy of the XHTML rendering.

Further Information pursuant to Article 10 of the EU Audit Regulation

We were elected as group auditor by the annual general meeting on May 17, 2023. We were engaged by the supervisory board on August 22, 2023. We have been the group auditor of the Wacker Chemie AG without interruption since the financial year 2006.

We declare that the opinions expressed in this auditor’s report are consistent with the additional report to the audit committee pursuant to Article 11 of the EU Audit Regulation (long-form audit report).

Other matter – Use of the Auditor’s Report

Our auditor’s report must always be read together with the audited consolidated financial statements and the audited group management report as well as the examined ESEF documents. The consolidated financial statements and group management report converted to the ESEF format – including the versions to be entered in the company register – are merely electronic renderings of the audited consolidated financial statements and the audited group management report and do not take their place. In particular, the ESEF report and our assurance opinion contained therein are to be used solely together with the examined ESEF documents made available in electronic form.
