Annual Report 2013

Independent auditor’s report.

To Deutsche Telekom AG, Bonn.

Report on the consolidated financial statements.

We have audited the accompanying consolidated financial statements of Deutsche Telekom AG, Bonn, and its subsidiaries, which comprise the consolidated statement of financial position, the consolidated income statement and statement of comprehensive income, the consolidated statement of changes in equity, the consolidated statement of cash flows and the notes to the consolidated financial statements, for the financial year from January 1 to December 31, 2013.

Board of Management’s responsibility for the consolidated financial statements.

The Board of Management of Deutsche Telekom AG, Bonn, is responsible for the preparation of these consolidated financial statements. This responsibility includes that these consolidated financial statements are prepared in accordance with International Financial Reporting Standards, as adopted by the EU, and the additional requirements of German commercial law pursuant to § 315a (1) HGB (“Handelsgesetzbuch”: German Commercial Code) and that these consolidated financial statements give a true and fair view of the net assets, financial position and results of operations of the Group in accordance with these requirements. The Board of Management is also responsible for the internal controls as the Board of Management deems to be necessary to enable the preparation of consolidated financial statements that are free from material misstatement, whether due to fraud or error.

Auditor’s responsibility.

Our responsibility is to express an opinion on these consolidated financial statements based on our audit. We conducted our audit in accordance with § 317 HGB and German generally accepted standards for the audit of financial statements promulgated by the Institut der Wirtschaftsprüfer (Institute of Public Auditors in Germany) (IDW), and additionally observed the International Standards on Auditing (ISA). Accordingly, we are required to comply with ethical requirements and plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free from material misstatement.

An audit involves performing audit procedures to obtain audit evidence about the amounts and disclosures in the consolidated financial statements. The selection of audit procedures depends on the auditor’s professional judgment. This includes the assessment of the risks of material misstatement of the consolidated financial statements, whether due to fraud or error. In assessing those risks, the auditor considers the internal control system relevant to the entity’s preparation of consolidated financial statements that give a true and fair view. The aim of this is to plan and perform audit procedures that are appropriate in the given circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Group’s internal control system. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of accounting estimates made by the Board of Management, as well as evaluating the overall presentation of the consolidated financial statements.

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Audit opinion.

According to § 322 (3) sentence 1 HGB we state that our audit of the consolidated financial statements has not led to any reservations.

In our opinion based on the findings of our audit, the consolidated financial statements comply, in all material respects, with IFRSs, as adopted by the EU, and the additional requirements of German commercial law pursuant to § 315a (1) HGB and give a true and fair view of the net assets and financial position of the Group as at December 31, 2013 as well as the results of operations for the financial year then ended, in accordance with these requirements.

Report on the Group management report.

We have audited the accompanying Group management report of Deutsche Telekom AG, Bonn, which is combined with the management report of the Company, for the financial year from January 1 to December 31, 2013. The Board of Management of Deutsche Telekom AG is responsible for the preparation of the combined management report in accordance with the requirements of German commercial law applicable pursuant to § 315a (1) HGB. We conducted our audit in accordance with § 317 (2) HGB and German generally accepted standards for the audit of the combined management report promulgated by the Institut der Wirtschaftsprüfer (Institute of Public Auditors in Germany) (IDW). Accordingly, we are required to plan and perform the audit of the combined management report to obtain reasonable assurance about whether the combined management report is consistent with the consolidated financial statements and the audit findings, as a whole provides a suitable view of the Group’s position and suitably presents the opportunities and risks of future development.

According to § 322 (3) sentence 1 HGB we state that our audit of the combined management report has not led to any reservations.

In our opinion based on the findings of our audit of the consolidated financial statements and combined management report, the combined management report is consistent with the consolidated financial statements, as a whole provides a suitable view of the Group’s position and suitably presents the opportunities and risks of future development.
