Independent Auditor’s Reports (Group) Independent auditor’s report To Siemens Aktiengesellschaft, Berlin and Munich Report on the audit of the consolidated financial statements and of the group management report Opinions We have audited the consolidated financial statements of Siemens Aktiengesellschaft, Berlin and Munich, and its subsidiaries (the Group), which comprise the consolidated statements of income and comprehensive income for the fiscal year from October 1, 2022 to September 30, 2023, the consolidated statements of financial position as of September 30, 2023, the consolidated statements of cash flows and changes in equity for the fiscal year from October 1, 2022 to September 30, 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 Siemens Aktiengesellschaft, which is combined with the management report of Siemens Aktiengesellschaft, for the fiscal year from October 1, 2022 to September 30, 2023. In accordance with the German legal requirements, we have not audited chapter 11 “EU Taxonomy disclosure” of the group management report, the sections “8.5.1 Internal Control System (ICS) and ERM” and “8.5.2 Compliance Management System (CMS)” in chapter 8.5 of the combined management report as well as the content of the Corporate Governance Statement which is published on the website stated in the combined management 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 International Financial Reporting Standards (IFRSs) as adopted by the European Union (EU), and the additional requirements of German commercial law pursuant to Sec. 315e (1) HGB [“Handelsgesetzbuch”: German Commercial Code] as well as with full IFRSs as issued by the International Accounting Standards Board (IASB), and, in compliance with these requirements, give a true and fair view of the assets, liabilities and financial position of the Group as of September 30, 2023 and of its financial performance for the fiscal year from October 1, 2022 to September 30, 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 chapter 11 “EU Taxonomy disclosure” of the group management report, the sections “8.5.1 Internal Control System (ICS) and ERM” and “8.5.2 Compliance Management System (CMS)” in chapter 8.5 of the group management report and the content of the Corporate Governance Statement. Pursuant to Sec. 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 Sec. 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). We performed the audit of the consolidated financial statements in supplementary compliance with the International Standards on Auditing (ISAs). Our responsibilities under those requirements, principles and standards 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 Art. 10 (2) f) of the EU Audit Regulation, we declare that we have not provided non-audit services prohibited under Art. 5 (1) of the EU Audit Regulation. We believe that the audit 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 fiscal year from October 1, 2022 to September 30, 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. Below, we describe what we consider to be the key audit matters: Revenue recognition on construction-type contracts Reasons why the matter was determined to be a key audit matter: The Group conducts a significant portion of its business under construction-type contracts, particularly in the Mobility business. Revenue from long-term construction-type contracts is recognized in accordance with IFRS 15, Revenue from Contracts with Customers, generally over time under the percentage-of-completion method. We consider the accounting for construction-type contracts to be an area posing a significant risk of material misstatement (including the potential risk of management override of internal controls) and accordingly a key audit matter, because management’s assessments significantly impact the determination of the extent of progress towards completion. These assessments include, in particular, the scope of deliveries and services required to fulfill contractually defined obligations, total estimated contract costs, remaining costs to completion and total estimated contract revenues, as well as contract risks including technical, political, regulatory, legal and supply chain risks. 2
