To our shareholders 5 n Net debt increased by 2.3 percent compared with the end of 2011 to EUR 41.0 billion. n Free cash flow (EUR 2.8 billion) as well as proceeds from the sale of shares in Telekom Srbija (EUR 0.4 billion) in particular had a positive impact. n Dividend payments including to non-controlling interests (EUR 3.4 billion), and effects in connection with the AT&T transaction (EUR 0.3 billion) had a negative impact, as did exchange rate and other effects (EUR 0.4 billion). n Net debt decreased by EUR 2.3 billion compared with the first half of the prior year. n Net profit increased to EUR 0.9 billion. n In the first half of 2011, T-Mobile USA had been classified as a discontinued operation. The discontinuation of depreciation and amortization in accordance with IFRS 5 and the recognition of deferred tax liabilities had a positive net effect. n In the first half of 2012, the loss from financial activities improved, particularly as a result of the sale of shares in Telekom Srbija. Income tax decreased year-on-year, mainly as the classifica- tion of T-Mobile USA as a discontinued operation was reversed (in December 2011). n Shareholders’ equity decreased by EUR 2.3 billion compared with the end of 2011. n Positive effects from net profit (EUR 0.9 billion) and currency translation (EUR 0.9 billion). n The recognition of actuarial gains and losses (net total of EUR 0.7 billion) directly in equity, and dividend payments including to non-controlling interests (EUR 3.4 billion) reduced the level of shareholders’ equity.

To our shareholders 7 In the first half of the year, Deutsche Telekom succeeded in escaping the darkened sentiment in the sector, with the T-Share rising by 2.5 percent on a total return basis (share price performance plus reinvested dividend). The positive sentiment of the T-Share was attributable in particular to sound financial figures in the first quarter. Market participants also rated our confirmed shareholder remuneration policy positively. In May 2012, a dividend of EUR 0.70 was paid for each share carrying dividend rights in accordance with a resolution by Deutsche Telekom AG’s shareholders’ meeting. The amount of the dividend corresponded to the shareholder remu- neration policy announced in February 2010. In line with this policy, a total of EUR 3.0 billion was paid out to Deutsche Telekom AG’s shareholders. Highlights in the second quarter of 2012. Developments at senior management level. Effective midnight May 2, 2012, Thomas Sattelberger’s appointment as member of the Board of Management responsible for Human Resources and as Labor Director came to an end. Effective May 3, 2012, the Supervisory Board appointed Prof. Marion Schick as member of the Board of Management responsible for Human Resources and as Labor Director. Effective midnight May 31, 2012, Dr. Manfred Balz’s appointment as member of the Board of Management responsible for Data Privacy, Legal Affairs and Compliance came to an end. Effective June 1, 2012, the Supervisory Board appointed Dr. Thomas Kremer as member of the Board of Management responsible for Data Privacy, Legal Affairs and Compliance. Partnerships. Together with the credit card provider MasterCard, we are giving a new boost to paying by smartphone. The aim of our strategic partner- ship is to enable customers to make payments conveniently, easily and securely from wherever they are. Regulatory decisions. The Federal Network Agency intends to revoke the prohibition on Telekom Deutschland GmbH’s VDSL price model. In a provi- sional decision on April 2, 2012, the Federal Network Agency had rejected the model, which had become known as the VDSL contingent model, presented by Telekom Deutschland in ex-post control proceedings. A new EU roaming regulation entered into force on July 1, 2012. In contrast to the European Commission’s original draft, the final regulation contains tighter provisions, setting lower price caps and expanding the transparency measures to also include roaming outside the European Union. For more details, please refer to “The economic environment” (page 8). Investments in networks and new spectrum. In Germany, we have already met the LTE roll-out obligations in 14 of the 16 federal states. Thus the only gaps in coverage left to close are in Brandenburg and Mecklenburg-Western Pomerania. In Hungary we are the first company to provide mobile Internet services based on 4G/LTE mobile communications technology. 4G/LTE ser- vices are not only available in the capital city Budapest, but also in the entire Budapest conurbation and some other cities. In April, the U.S. regulatory authority for the telecommunications market, the Federal Communications Commission (FCC), announced its approval of the transfer of Advanced Wireless Service spectrum licenses in the United States. The licenses were transferred effective May 4, 2012. The licenses were part of the compensation that AT&T had to provide to Deutsche Telekom following the termination of the agreement for the sale of T-Mobile USA. New corporate customer agreements. Our corporate customer arm, T-Systems, has signed an agreement with the Swiss industrial group Georg Fischer on the provision of global ICT services. For the contractual term of six years and three months, T-Systems will pool Georg Fischer’s IT infrastructure and manage it as cloud services. We won the automotive manufacturer BMW as a customer for mobile services. The contract will run until the end of 2019 and, in addition to mobile cards for more than 50,000 BMW employees, provides for a direct link between the mobile cards and BMW’s business processes. RWE Deutschland is relying on the infrastructure and services provided by Deutsche Telekom to communicate with 15,000 digital electricity meters in Mülheim/Ruhr. To this end, we installed the smart meters and the communi- cation boxes necessary for remote reading. The “Mülheim zählt” (Mülheim counts) project is to date the largest smart metering project in Germany. In total over 100,000 devices are to be installed before the end of this year. Employees. In the negotiations for the 2012 collective bargaining for Deutsche Telekom AG, Telekom Deutschland GmbH and its service compa- nies, and T-Systems, the parties have reached agreement. As a result of this collective bargaining, the salaries of employees covered by collective agree- ments will gradually increase by 6.5 percent overall by 2013. The collective agreements run until the end of January and March 2014, respectively. The German Federal Government and the Bundestag, the lower house of the German Parliament, adopted the draft 2012/2013 Federal Civil Servant Remuneration and Pension Adjustment Act (Bundesbesoldungs- und Ver- sorgungsanpassungsgesetz). The bill provides for the collective agreement for the federal public sector to be transferred to civil servants. Pay for civil servants at Deutsche Telekom will gradually increase by 5.7 percent overall by August 2013. Awards. In May 2012, the readers of “connect” magazine voted us the “Mobile communications network operator of the year” in Germany for the thirteenth time in a row. We were also voted the best mobile communications network operator in Austria by the readers of “connect.”

Interim Group management report 9 ƒ Seamless connectivity for the Gigabit Society. With the seamless inte- gration of our high-speed networks, we guarantee the best connectivity for our customers everywhere and at all times. ƒ ƒ More innovation by cooperation. We create a basis for sustainable innovation using the efficiency of three tiers: our own developments, partnering and ventures. Secure cloud solutions. Our many years of experience in the area of cloud solutions make us almost unique in the global market and are the basis for our market success. Best-in-class customer experience. We want to offer our customers the best everywhere and at all times: from advertising, our shops and products, through to understandable general terms and conditions. ƒ The four areas of operation will be implemented systematically. In the future, we will focus on three principles: Compete, Transform and Innovate. Specifically, this means: ƒ We compete for our customers to maintain or improve our market position. ƒ We transform our processes and systems to remain competitive. ƒ We innovate in all areas of our Company to achieve further growth and drive forward innovation. Apart from the revised strategic guidelines, the areas of operation and the ways and means with which we implement our strategy, other core elements of the strategy remain unchanged. This includes, for example, our business model, as well as our innovation and growth areas at the ambition level already an- nounced: Revenue in billions of € Mobile Internet Connected home Internet services T-Systems (external revenue)* Intelligent networks (energy, healthcare, connected car) * excluding revenue from “intelligent networks.” H1 2012 3.1 3.2 0.4 3.2 0.1 Ambition level for 2015 ≈ 10 ≈ 7 2 to 3 ≈ 8 ≈ 1 Deutsche Telekom remains on track. Our strategy defines the framework for the long-term success of Deutsche Telekom. Group structure, strategy and management. With regard to our Group structure and management, please refer to the notes in the 2011 combined management report (2011 Annual Report, page 60 et seq.). No significant changes were recorded in this area from the Group’s point of view. Since January 1, 2012, Deutsche Telekom has pooled the tasks and functions of the Digital Services growth business as well as the Internet service provider STRATO, which as of December 31, 2011 were still largely part of the Germany operating segment, as the Digital Business Unit (DBU) under Group Headquar- ters & Shared Services. For more information, please refer to the disclosures under segment reporting in the interim consolidated financial statements (pages 35 and 36). Group strategy. Our refined strategy lays the foundation for our future success. Deutsche Telekom is one of the world’s leading providers of telecommunica- tions and information technology. On the one hand, we operate in highly competitive markets in traditional line business, but on the other, there are also growth opportunities in markets for products such as mobile data usage, and cloud and Internet services. We therefore formulated the strategy Fix – Transform – Innovate in 2010 and since then have implemented it with success: For example, we successfully launched the joint venture Everything Everywhere in the United Kingdom, integrated our fixed-network and mobile activities in several countries and are driving forward the comprehensive network build-out with LTE or fiber optics. We also offer consumers and our business customers more and more innovative services, such as secure TelekomCloud products. Two years on, this basic orientation remains; Deutsche Telekom’s chosen course continues unchanged. However, we have decided to simplify and focus our strategy and center it even more firmly on the customer. This can be seen in our revised strategic guidelines, which express how we want our customers to see us: Deutsche Telekom – My first choice for connected life and work. We intend to achieve this by continuing to systematically implement our strategic areas of operation, which we adjusted to focus on core success factors for Deutsche Telekom in our markets: Seamless connectivity for the Gigabit Society More innovation by cooperation Secure cloud solutions Best-in-class customer experience

Group EBIT decreased by EUR 0.4 billion to EUR 2.8 billion compared with the first half of 2011 due to the aforementioned effects on EBITDA but also to the increase in depreciation expense of around EUR 0.7 billion. This is attributable to the classification of our United States operating segment as a discontinued operation in the prior-year period. As a result, no depreciation, amortization or impairment losses were recorded pro rata temporis for this segment. The classification as a discontinued operation was reversed as of the end of the 2011 financial year. Average number of employees.

Profit before income taxes decreased by EUR 0.1 billion to EUR 1.7 billion year-on-year in the first quarter of 2012. The decrease of EUR 0.3 billion in the loss from financial activities partly offset the aforementioned effects. The change in the loss from financial activities was due in part to the sale of the shares in Telekom Srbija. Net profit. Net profit increased from EUR 0.8 billion to EUR 0.9 billion, which was, among other factors, due to lower income tax expense. For further information, please refer to the interim consolidated financial statements (page 34). Profit attributable to non-controlling interests increased, primarily as a result of the sale of shares in Telekom Srbija. The aforementioned effects resulted in a EUR 0.2 billion increase in profit compared with the first six months of 2011. Of which: civil servants (in Germany, with an active service relationship) 23,385 25,370 Average headcount decreased by 3.8 percent compared with the prior-year reporting period. This trend is largely attributable to a lower international headcount, which was down by 6.3 percent. In our Europe operating segment, downsizing programs carried out as a result of programs to enhance efficiency contributed to this lower figure. In the United States operating segment, fewer staff were employed in customer support and sales units compared with the prior-year period. Average headcount in Germany decreased by 1.4 percent, mainly due to socially responsible staff restructuring and reduction in the Germany operat- ing segment and a reduction in Vivento’s headcount at Group Headquarters & Shared Services. The overall decrease was partially offset by increased staff levels in the Systems Solutions operating segment, attributable to employees taken on in connection with big deals.

Free cash flow in the Group before dividend payments and spectrum investment and before PTC and AT&T transactions remained largely stable in the reporting period compared with the prior-year period. Both net cash from operating activities and cash capex decreased slightly year-on-year. The decrease in cash capex relates mainly to the Europe operating segment. Net cash from operating activities (before PTC and AT&T transactions) in the first half of 2012 decreased by EUR 0.2 million compared with the prior-year period to EUR 6.4 billion. Apart from the fact that cash outflows were recorded at different points in time over the year and that cash discounts were used to a larger extent, this decrease was primarily attributable to the following cash flows: cash outflows of EUR 0.1 billion in connection with investigations by the U.S. authorities into contracts signed by the F.Y.R.O. Macedonia and Montenegro, a reduction of EUR 0.2 billion in income tax paid, a reduction of EUR 0.1 billion in net interest payments and cash inflows of EUR 0.1 billion from the canceling of interest rate swaps. Furthermore, the dividend payments made by the Everything Everywhere joint venture in the first half of 2012 increased by EUR 0.1 billion year-on-year.

Interim Group management report 15 The number of contract customers in the mobile communications portfolio increased by 2.2 percent in the first six months of 2012. In particular, rate pack- ages with integrated data flat rates for the mobile Internet (Call & Surf Mobil, Complete Mobil, and Mobile Data), especially the promotional rates included, sold well. Through these packages we migrated a large number of customers from pure voice rates to higher-value data rate plans. In the area of text messaging, we were even more successful in marketing our “SMS Flat all net” rate option in the first half of 2012. The decrease in the number of prepay customers compared with December 31, 2011 is largely attributable to the deactivation of inactive cards. This decline was partly compensated by measures including the positioning of congstar in our Telekom shops for the first time. Business Customers. Connected work with innovative solutions. The number of fixed-network lines in the Business Customers area as of June 30, 2012 was 1.2 percent higher than at year-end 2011. In Internet usage, customers are increasingly opting for plans with higher bandwidths such as Business Complete. Products in the area of connected work developed positively. Accordingly, we recorded a growth trend in our CompanyConnect dedicated Internet connections. In the field of data communications, we significantly increased the number of networks and connections with Internet-based data networks (IP VPNs) and high-bandwidth location networking. With a clear focus on rate plans with integrated data flat rates for the mobile Internet, the new set of mobile plans we introduced in February 2011 helped to increase subscriber numbers compared with the prior year. Subscriber numbers continued to rise compared with year-end in the area of machine-to-machine mobile communications as well as among contract customers, due not least to the marketing kick-off of new, attractive mobile rate plans for business customers. In the second quarter of 2012, we won (back) a number of business customers for our mobile services, such as BMW, Heidelberger Druck and Schwäbisch Hall. Wholesale. In the first half of 2012, the number of unbundled local loop lines (ULLs) remained virtually unchanged from year-end 2011, whereas the number of our bundled wholesale lines declined by 87 thousand. This trend is expected to continue in the next few years, due in particular to the fact that our competitors are switching from bundled to unbundled wholesale products or to their own infrastructure.

The prior-year figures have been adjusted for better comparability. Total revenue. We took measures to ensure continued value-enhancing growth in our core markets, i.e., the broadband fixed network and mobile communications. Revenue in the first half of 2012 was down 2.7 percent year-on-year, which was mainly attributable to the downward trend in voice telephony, both in mobile and fixed-network business. This trend was partly offset by increasing demand for complete packages comprising mobile data or TV rate plans. As a result, the decrease was smaller than that recorded in the first half of 2011 compared with the first half of 2010. Revenue growth in the fixed network was a result of the successful marketing of Entertain and add-on options. However, this positive trend was not sufficient

Macedonia and Montenegro. Total. In the first half of 2012, we maintained our customer base in the Europe operating segment despite the still strained economic situation and intense competition. In the fixed network, we increased the number of broadband lines compared with the end of 2011 thanks to the focus on rolling out broadband technology, and thus partially offset the line loses in traditional fixed-network business. Compared with the prior quarter, we even substantially reduced losses in fixed- network lines to a level that is now below 1 percent. In mobile communications, we recorded a slight increase of around 1 percent in the total customer base compared with the end of the prior year, mainly driven by contract net additions. In the prepay segment, the number of customers only grew markedly in Poland due to a change in the deregistration procedure in response to a general change in deregistration policies across the industry in the previous year. Fixed network. Telephony, Internet and TV. The IPTV business again proved itself as a consis- tent growth driver; compared with the end of 2011, the number of IPTV custom- ers increased by around 8 percent. Due to innovative rate plans, for example TV together with Internet access, we further expanded our customer base in most countries of our operating segment with fixed-network operations. Compared with December 31, 2011, the number of retail broadband lines marketed increased by around 1.2 percent to 4.6 million lines. Almost all countries in our Europe operating segment contributed to this result. The highest growth in absolute terms compared with the end of 2011 was achieved in Romania, where the increase was mainly attributable to DSL business. In Hungary, growth was primarily driven by an increase in the number of broadband cable connections. In the Czech Republic, the number of DSL lines grew by as much as 5 percent compared with the year-end. As of June 30, 2012, some 10.2 million customers in our Europe operating segment used a fixed-network line. This is a reduction of 3.0 percent compared with the end of 2011, which is largely attributable to line losses in traditional telephony in Croatia, Greece, Romania and Hungary. In Greece and Romania in particular, the economic situation and the resulting intense competitive pressure caused a decline in the number of customers.

Interim Group management report 19 Total revenue. In the first half of 2012, our Europe operating segment generated total revenue of EUR 7.2 billion, down 4.3 percent compared with the prior-year level. The de- velopment of exchange rates against the euro – mainly driven by the Hungarian forint and the Polish zloty – had a significantly negative impact on our revenue: Almost half of the revenue decline was due to exchange rate effects. Adjusted for this effect, segment revenue decreased by just 2.3 percent compared with the level in the prior-year period. The first half of the year was characterized by further price reductions in most European countries, driven on the one hand by intense competition and on the other by the reduction in mobile termination rates imposed by the regulatory authorities. Furthermore, the difficult economic situation, especially in Southern and Eastern European countries, had a negative impact. For example, around 60 percent of the decrease in revenue from operations was attributable to our Greek subsidiaries. In Croatia and Slovakia, fixed-network and mobile business was also impacted by declines in revenue. Adjusted for exchange rate effects, Hungary recorded an increase in revenue and partially offset revenue losses at segment level. Growth in (fixed-network and mobile) broadband, television, ICT and energy had a positive impact overall on the revenue trend at segment level. These growth areas partially compensated for the negative revenue effects from voice telephony. This shows the success of our strategy to drive forward the roll-out of broadband technologies in both fixed-network and mobile operations in combination with attractive rate plans. In mobile communications, we recorded substantial further growth in data revenue, with an increase of around 17 percent to EUR 0.6 billion; adjusted for exchange rate effects, data revenue even in- creased by approximately 20 percent. While Greece generated mobile data revenue just under the prior-year level, adjusted for exchange rate effects, all other countries of our Europe operating segment, but in particular the Netherlands, Austria, Poland and the Czech Republic, contributed to the strong growth. EBITDA, adjusted EBITDA. Our Europe operating segment generated adjusted EBITDA of EUR 2.4 billion in the first half of 2012, a year-on-year decrease of 6.6 percent. Without the strong negative exchange rate effects, especially from the translation of the Hungarian forint and the Polish zloty, adjusted EBITDA decreased by just 4.5 percent. This operational decline at segment level resulted from lower adjusted EBITDA compared with the prior-year period, especially in Poland, Hungary, the Czech Republic and Slovakia. These decreases were partially offset by higher EBITDA contributions in the Netherlands and in the Romanian and Greek mobile operations. Overall, the decrease in revenue year-on-year had a negative impact on the development of EBITDA. In addition, changes in legislation (for example, as part of national austerity programs) adversely affected our EBITDA. In Greece, for instance, our earnings in the first half of 2012 were impacted by the real estate tax introduced in September last year. We also expect our results to be negatively impacted by exceptional government measures in the near future. In Hungary, the development of EBITDA will be affected by the special levy introduced as of July 1, 2012 on top of the existing special tax. The same applies for the mobile communications tax reintroduced in Croatia as of January 26, 2012 which, however, was abolished again as of July 9, 2012. By systematically reducing overheads through our efficiency enhancement measures, which are primarily reflected in lower personnel costs and cost of materials, as well as by addressing customer needs in a targeted way, especially with regard to customer retention, we partially offset the negative effects from the decline in revenue. Development of operations in selected countries. Greece. Revenue in Greece totaled EUR 1.6 billion in the first half of 2012, a year-on-year decrease of 5.8 percent, which was mainly attributable to fixed-network business and here primarily to line losses of some 11 percent in traditional telephony. Since regulation of fixed-network business in Greece continues to be very strict, we were not yet able to proceed with broadband customer acquisitions as planned and thus to generate the associated revenue in full. The difficult economic situation and strong competition also had an impact on mobile business compared with the first half of the prior year, which is clearly reflected in the decline in service revenues and lower terminal equipment sales. Adjusted EBITDA decreased to EUR 610 million in Greece during the reporting period, a year-on-year decline of 3.2 percent. On the one hand, this was due to lower revenue and to decisions by public authorities on the other. In September 2011, the Greek government introduced a real estate tax, which accounted for around a third of the year-on-year decline in EBITDA in Greece in the first half of 2012. We largely offset the revenue losses through targeted measures for customer acquisition and retention in mobile business and through our programs to increase efficiency in mobile and fixed-network business. The success of the efficiency enhancement programs is primarily reflected by lower personnel costs due in part to a reduced headcount and in part to the agree- ments with the trade unions concluded in the previous year. Hungary. In Hungary, we generated revenue of EUR 668 million in the first half of 2012, a year-on-year decrease of 7.5 percent. Adjusted for the negative exchange rate performance of the Hungarian forint against the euro, revenue from operations increased by 1.5 percent. This year-on-year increase is attributable to growth in fixed-network business which again is attributable to the energy resale business. But thanks to increased revenue from broadband, television and ICT as well as from terminal equipment sales, we also offset losses from traditional telephony. In mobile communications, service revenues declined compared with the prior-year period, mainly as a result of price cuts due to competition as well as a reduction in termination rates imposed by the regulatory authorities. These effects were partially offset within service rev- enues due to higher data revenue. There was also a positive contribution to revenue from the growth in terminal equipment revenue as a result of the sub- stantial increase in smartphones as a proportion of all terminal devices sold. Adjusted EBITDA amounted to EUR 237 million in the first half of 2012, representing a year-on-year decrease of 18.0 percent. As with revenue, this decrease was due to the unfavorable exchange rate performance (around 44 percent) of the Hungarian forint against the euro. Adjusted for this factor, EBITDA decreased by 10.1 percent. This was due on the one hand to a positive one-time effect in the first quarter of 2011, which was not repeated to the same extent in the current six-month period. On the other hand, increased customer acquisition and retention costs as well as costs from the low-margin energy resale business counteracted the positive revenue effects. Savings in overheads only partially offset increases in direct costs. Poland. Revenue in Poland totaled around EUR 831 million in the first half of this year, down by 6.9 percent year-on-year. Adjusted for the significantly negative exchange rate performance of the Polish zloty against the euro, revenue remained at around the prior-year level. Declining revenue from voice telephony due to intense competition and the reduction in mobile termination rates impacted negatively on service revenues especially in the consumers segment. This was partially offset by encouraging growth in data business. In addition, increased terminal equipment sales made a positive contribution to revenue, mainly due to the successful marketing of smartphones. Adjusted EBITDA amounted to EUR 266 million in the first half of the year, down 16.9 percent year-on-year. Adjusted for negative exchange rate effects, the decrease was 10.7 percent. The decline was attributable to increased customer

This decrease in net customers in the first half of 2012 was an improvement compared to a net decrease of 150,000 for the first half of 2011. In the first half of 2012, contract customer losses were substantially offset by prepay customer growth. In the first half of 2012, T-Mobile USA lost 710,000 contract customers compared to 663,000 contract customers lost in the first half of 2011. In the first half of 2012, losses in branded contract customers declined as they were impacted by lower branded contract customer churn, which continues to be a key strategic focus for 2012. Additionally, total machine-to-machine customers continued to grow in the first half of 2012, although at a slower rate than the first half of 2011, to a total of 2.8 million customers at June 30, 2012. In the first half of 2012, T-Mobile USA had 692,000 net prepay customer additions compared to 513,000 net prepay customer additions in the first half of 2011. The signifi- cant improvement in net branded prepay customer additions in the first half of 2012 was due to the success of unlimited Monthly 4G prepay plans and the discontinuation of the company’s FlexPay product that historically had higher churn. Additionally, MVNO customers continued to grow in the first half of 2012, and totaled 3.8 million at June 30, 2012. T-Mobile USA’s blended churn decreased to an average of 3.3 percent per month in the first half of 2012, compared to an average of 3.4 percent per month in the first half of 2011. The year-on-year decrease in blended churn was due primarily to lower branded contract churn from a change in the mix of T-Mobile USA’s contract product portfolio. Branded contract churn de- creased by 0.3 percentage points to 2.3 percent compared with the prior-year period. The contract product portfolio was adjusted through the discontinua- tion of certain products that had higher churn, such as FlexPay Contract. The continued strategic focus on churn reduction, including credit optimization initiatives, contributed to the decrease. Development of operations.

Total revenue for the United States operating segment (T-Mobile USA) was EUR 7.7 billion in the first half of 2012, an increase of 5.3 percent compared to EUR 7.3 billion in the first half of 2011 due to exchange rate effects. In U.S. dollars, total revenue declined by 2.7 percent year-on-year due primarily to a decrease in service revenues partially offset by an increase in equipment revenues associated with T-Mobile USA’s Value plans and other fee revenues. Service revenues declined due to a decrease in branded contract customers (contract customers excluding machine-to-machine) and changes in the customer mix towards lower priced Value rate plans. This was partially offset by prepay service revenue growth associated with the continued success of unlimited Monthly 4G prepay plans introduced in the second quarter of 2011. Data service revenues increased by 8.7 percent in the first half of 2012 driven by increased smartphone plan adoption which helped offset voice revenue declines. Equipment sales increased, despite lower volumes, by 14.4 percent due to handset program pricing changes in connection with T-Mobile USA’s Value plans, which were launched in the third quarter of 2011.

Revenue generated by our Systems Solutions operating segment in the first half of 2012 was slightly lower than in the prior-year period, largely due to the continuing price pressure. Nevertheless, significant new deals were concluded, such as those with Daimler, British American Tobacco (BAT) and the Swiss industrial group Georg Fischer. Our standard solutions from our growth area of cloud computing won out over strong competition, winning us the contracts with these three corporate customers. T-Systems expanded its dynamic resources accordingly in the first half of 2012 (please also refer to the 2011 Annual Report, page 105 et seq.). In another pleasing development, utilities company RWE Deutschland has selected Deutsche Telekom as its partner for the largest smart metering project to date in Germany. Order entry decreased by 14.7 percent compared with the first half of the prior year. The figures in the first quarter of 2011 included the comprehensive outsourcing agreement with Everything Everywhere totaling approximately EUR 500 million. The growth in order entry in the second quarter of 2012 was unable to compensate for this effect. The number of servers managed and serviced declined compared with the prior-year period. This was largely due to technological progress. The increas- ing demand for our ICT services as a consequence of new deals is now met by more powerful servers and improved utilization of their capacity. A similar development can be seen at the data centers which have been consolidated to produce larger, more powerful units. Encouragingly, the Systems Integration unit billed many more hours and thus increased its capacity utilization. Development of operations.

Total revenue in our Systems Solutions operating segment in the reporting period amounted to EUR 4.5 billion, a slight year-on-year decrease of 1.0 percent. This decline is primarily attributable to a decrease of 2.3 percent in internal revenue from Deutsche Telekom entities following IT cost saving initiatives taken at Group level. External revenue decreased only slightly by 0.5 percent, mainly due to revenue generated in Germany. International revenue, by con- trast, increased. EBITDA, adjusted EBITDA. Adjusted EBITDA in our Systems Solutions operating segment increased by 6.2 percent in the reporting period as a result of the restructuring and efficiency enhancement program launched. The adjusted EBITDA margin improved from 8.5 to 9.1 percent. EBITDA decreased by 31.0 percent due to provisions recog- nized in the first half of 2012 for the planned early retirement arrangements for civil servants and other restructuring measures.

Interim Group management report 25 Risks and opportunities. This section provides important additional information and explains recent changes in the risks and opportunities as described in the combined manage- ment report for the 2011 financial year (2011 Annual Report, page 131 et seq.). Readers are also referred to the Disclaimer at the end of this report. Litigation. Prospectus liability proceedings. On May 16, 2012, the senate of the Frankfurt Higher Regional Court ruled in the model proceedings (“Musterverfahren”) that there were no errors in the prospectus for Deutsche Telekom’s third public offering and that Deutsche Telekom is not liable. This decision is not final and legally binding. The plaintiffs’ side (lead plaintiffs and summoned third parties) has filed an appeal against the decision with the Federal Court of Justice. Eutelsat arbitration proceedings. Eutelsat S.A. is seeking revocation by French courts of the ruling of the court of arbitration which refused to include Media Broadcast GmbH in the arbitration proceedings due to lack of jurisdic- tion. As part of the arbitration proceedings, Eutelsat S.A. submitted its statement of claim on February 29, 2012, to which Deutsche Telekom responded on May 9, 2012. The financial impact of the proceedings cannot be estimated with sufficient certainty at this point in time. Shareholder litigation. In its ruling of January 6, 2012, the Cologne Regional Court dismissed in its first instance the nullity and rescission suit filed by a shareholder against resolutions adopted by the Deutsche Telekom shareholders’ meeting in 2011 approving the actions of the members of the Board of Manage- ment and Supervisory Board, and seeking the nullity of the annual financial statements for the 2010 financial year. The shareholder has appealed the decision. Litigation concerning decisions by the Federal Network Agency. In March 2012, the Cologne Administrative Court largely revoked the approval of the one-time charges for the leasing of unbundled local loop lines from 2004. The rulings of the Cologne Administrative Court are final and legally binding. Accordingly, the Federal Network Agency must set the rates again. Year-end bonus for civil servants. In a decision dated January 17, 2012, the Federal Constitutional Court ruled that the abolition of the year-end bonus for Deutsche Telekom civil servants is constitutional. This move does not violate the principle of equal pay laid down in Article 3 (1) of the Basic Law in conjunc- tion with Article 33 (5) of the Basic Law. The Federal Administrative Court now has to rule on the current litigation on claims for payment of the difference be- tween the payment under the Federal Act on Bonus Payments and the reduced payment under the Deutsche Telekom Special Allowance Ordinance, taking the decision of the Federal Constitutional Court into account. Reduced pay tables. In a ruling on December 15, 2009, the Stuttgart Administrative Court decided in two court proceedings to present the question of whether § 78 of the Federal Civil Service Remuneration Act is constitutional to the Federal Constitutional Court for decision. Referring to the decision to abolish the year-end bonus, the Federal Constitutional Court has since suggested to the Stuttgart Administrative Court that the question submitted be withdrawn. The Administrative Court has since withdrawn the question submitted to the Federal Constitutional Court and dismissed the actions in all cases in which the plaintiffs had not withdrawn them. We consider it unlikely that recourse will be taken to the courts in the cases still pending. Claim for damages by Kabel Deutschland GmbH. Telekom Deutschland GmbH was notified in early April 2012 that Kabel Deutschland Vertrieb und Service GmbH (KDG) had filed a claim with the Frankfurt Regional Court; the complaint was served on June 14, 2012. KDG demands a reduction in the annual charge for the rights to use cable duct capacities in the future, and the partial refund of payments made in the past in this connection. The financial impact of the proceedings cannot be estimated with sufficient certainty at this point in time. Mobile communications patent litigation. On April 24, 2012, the Düsseldorf Regional Court ruled in favor of the claim by IPCom against Telekom Deutsch- land GmbH concerning a breach of an IPCom patent in connection with the sale of UMTS-enabled devices manufactured by HTC and Nokia. On April 25, 2012, the European Patent Office in Munich ruled that the disputed patent is not legally valid. Both decisions are not yet final and legally binding/valid. We have appealed against the ruling of the Düsseldorf Regional Court and currently expect that it will not be enforced. IPCom has filed an appeal against the decision of the European Patent Office. Agreement was reached with IPCom on July 18, 2012 in the proceedings relating to the IPCom patent concerning a process for voice coding. IPCom waived all claims against the Deutsche Telekom Group arising from this patent and undertook to withdraw its patent infringement suit. In return, Deutsche Telekom has withdrawn its rescission suit against the patent. Further legal disputes with IPCom are still pending; it is currently not possible to estimate with sufficient certainty what financial impact these proceedings, including those regarding the alleged infringement of an IPCom patent as a result of the sale of UMTS-enabled HTC and Nokia devices, might have. Claims for damages due to price squeeze. In April 2012, two further compet- itors asserted their claims in court: QSC is seeking damages of EUR 7 million, DOKOM of EUR 4.5 million, plus interest in each case. Anti-trust proceedings. European Commission proceedings against Slovak Telekom and Deutsche Telekom. The European Commission decided on May 8, 2012 to send a statement of objections to Slovak Telekom and Deutsche Telekom. In this statement of objections, it communicates its preliminary opinion that Slovak Telekom, in which Deutsche Telekom AG holds a 51-percent stake, has breached European anti-trust law on the Slovakian broadband market. The European Commission intends to make the parent company, Deutsche Telekom, liable for this. We continue to see no basis for holding Deutsche Telekom liable for the alleged breach of anti-trust law by Slovak Telekom. Furthermore, we are convinced that Slovak Telekom complies with applicable law. Intense competition and the ongoing price erosion on the Slovak broadband market argue against any obstruction of competitors by Slovak Telekom. The statements of objections are not yet the final decision. Should the Commission uphold its allegations in the course of the proceedings, it may impose a fine on Slovak Telekom and Deutsche Telekom. The financial impact of the proceedings cannot be esti- mated with sufficient certainty at this point in time. Proceedings initiated by the Croatian competition authority against Hrvatski Telekom. In the proceedings initiated by the Croatian competition authority AZTN against Hrvatski Telekom (HT) and other mobile communications providers concerning alleged collusion in violation of anti-trust law relating to the introduction of a state levy on mobile communications, hearings in May 2012 marked the provisional end of the collection of evidence by the AZTN. HT continues to believe these allegations are unfounded. The financial impact of the proceedings cannot be estimated with sufficient certainty at this point in time. Furthermore, Deutsche Telekom intends to defend itself and/or pursue its claims resolutely in each of these court, conciliatory, and arbitration proceedings.

Interim consolidated financial statements 33 Significant events and transactions. Accounting policies. In accordance with § 37y of the Securities Trading Act (Wertpapierhandelsge- setz – WpHG) in conjunction with § 37w (2) WpHG, Deutsche Telekom AG’s half-year financial report comprises interim consolidated financial statements and an interim management report for the Group as well as a responsibility statement pursuant to § 297 (2) sentence 4 and § 315 (1) sentence 6 of the German Commercial Code (Handelsgesetzbuch – HGB). The interim consoli- dated financial statements were prepared in accordance with the International Financial Reporting Standards (IFRSs) applicable to interim financial reporting as adopted by the EU. The interim management report for the Group was prepared in accordance with the applicable provisions of the WpHG. Statement of compliance. The interim consolidated financial statements for the period ended June 30, 2012 are in compliance with International Accounting Standard (IAS) 34. As permitted by IAS 34, it has been decided to publish a condensed version com- pared to the consolidated financial statements at December 31, 2011. All IFRSs applied by Deutsche Telekom have been adopted by the European Commission for use within the EU. In the opinion of the Board of Management, the reviewed half-year financial report includes all standard adjustments to be applied on an ongoing basis that are required to give a true and fair view of the results of operations, financial po- sition and cash flows of the Group. Please refer to the notes to the consolidated financial statements as of December 31, 2011 for the accounting policies applied for the Group’s financial reporting (2011 Annual Report, page 165 et seq.). The United States operating segment (T-Mobile USA) has no longer been classified as a discontinued operation since December 20, 2011. The prior-year figures disclosed in the consolidated income statement have therefore been adjusted with retroactive effect. Since January 1, 2012, Deutsche Telekom has pooled the tasks and functions of the Digital Services growth business as well as the Internet service provider STRATO, which as of December 31, 2011 were still largely part of the Germany operating segment, as the Digital Business Unit (DBU) under Group Headquar- ters & Shared Services. Initial application of standards, interpretations and amendments to standards and interpretations in the reporting period relevant for the 2012 financial year. In October 2010, the IASB issued the pronouncement “Disclosures – Transfers of Financial Assets” as an amendment to IFRS 7 “Financial Instruments: Disclosures.” The amendments are applicable for financial years beginning on or after July 1, 2011. The European Union endorsed this pronouncement in November 2011. The amendments do not have an impact on the presentation of Deutsche Telekom’s results of operations, financial position or cash flows in the interim consolidated financial statements. In December 2010, the IASB issued the pronouncement “Deferred Tax: Re- covery of Underlying Assets – Amendments to IAS 12.” The pronouncement is effective for financial years beginning on or after January 1, 2012 and has not yet been endorsed by the European Union and as such has not yet been applied. The amendment would not have a material impact on the presentation of Deutsche Telekom’s results of operations, financial position or cash flows. For more detailed information on the aforementioned amendments, please refer to the “Summary of accounting policies” section in the notes to the con- solidated financial statements in the 2011 Annual Report (2011 Annual Report, page 165 et seq.). Changes in the composition of the Group. No major changes in the composition of the Deutsche Telekom Group occurred as of June 30, 2012. Selected notes to the consolidated statement of financial position. Non-current assets and disposal groups held for sale. Non-current assets and disposal groups held for sale decreased by EUR 0.3 billion against December 31, 2011. This was primarily due to the sale of the shares in Telekom Srbija totaling EUR 0.4 billion on January 25, 2012. Following the sale, the amount of EUR 0.2 billion disclosed as total other comprehensive income as of December 31, 2011 due to the increase of carrying amounts to fair value was reclassified to other financial income/expense. Of this figure, EUR 0.1 billion was attributable to non-controlling interests. Intangible assets and property, plant and equipment. Intangible assets increased in the first half of the year from EUR 50.1 billion to EUR 51.3 billion on account of additions of EUR 1.7 billion and exchange rate effects of EUR 0.9 billion, mainly from the U.S. dollar. This increase was partially offset by amortization of EUR 1.6 billion. The additions to intangible assets in the second quarter of the year included EUR 0.9 billion from the transfer of AWS spectrum licenses that were part of the compensation from AT&T relating to the termination of the agreement to sell T-Mobile USA. Until the approval of the transfer by the Federal Communica- tions Commission (FCC) in the second quarter of 2012, the licenses had been reported under other non-current assets. Property, plant and equipment decreased in the first half of the year by EUR 1.2 billion, from EUR 41.9 billion to EUR 40.7 billion. Additions of EUR 2.8 billion and exchange rate effects of EUR 0.4 billion, especially from the U.S. dollar and Hungarian forint, had an increasing effect, which was offset by depreciation of EUR 3.9 billion and disposals of EUR 0.1 billion. On June 30, 2012, Deutsche Telekom changed its estimates of the useful lives of property, plant and equipment in the United States operating segment. The useful lives of legacy mobile assets that have not yet been fully depreciated have been reduced in connection with the roll-out of high-bit-rate mobile tech- nology. This increased depreciation by EUR 0.1 billion in the first half of 2012.

Interim consolidated financial statements 35 Notes to the consolidated statement of cash flows. Deutsche Telekom paid EUR 1.4 billion to Elektrim and Vivendi in the first quarter of the prior year. This gave Deutsche Telekom full, undisputed owner- ship of PTC (PTC transaction). In accordance with the standards governing statements of cash flows, this total consisted of the following: EUR 0.4 billion net cash from operating activities, EUR 0.8 billion net cash used in investing activities and EUR 0.2 billion net cash used in financing activities. Net cash from operating activities. Net cash from operating activities in the first half of 2012 decreased by EUR 0.1 billion compared with the prior-year period to EUR 6.2 billion. Apart from the fact that the cash outflows were re- corded at different points in time over the year and that cash discounts were used to larger extent, this decrease was attributable, among other factors, to the following cash flows: cash outflows of EUR 0.3 billion in connection with the AT&T transaction relating to the termination of the agreement for the sale of T-Mobile USA and of EUR 0.1 billion in connection with investigations by the U.S. authorities into contracts signed by the F.Y.R.O. Macedonia and Montenegro. In the prior-year period, by contrast, cash outflows of EUR 0.4 billion were recorded for the PTC transaction. In addition, net cash from operating activities was impacted by lower income tax paid (EUR 0.2 billion), lower net interest payments (EUR 0.1 billion) and cash inflows from the canceling of interest rate swaps (EUR 0.1 billion) in the first half of 2012. Furthermore, the dividend pay- ments made by the Everything Everywhere joint venture in the first half of 2012 increased by EUR 0.1 billion year-on-year. Net cash used in investing activities. Net cash used in financing activities. Dividends (including to non-controlling interests) Repayment of eurobond Repayment of a medium-term note (current) Repayment of EIB loans Repayment of lease liabilities Net repayment of cash deposits from the Everything Everywhere joint venture Repayment of eurobond issued by OTE Repayment of U.S. dollar bonds PTC transaction Issuances of U.S. dollar bonds Commercial paper (net) Issuance of a medium-term note (non-current) Net cash flows for collateral deposited for hedging transactions Net liabilities to banks Utilization of the credit line by OTE Loans taken out with the EIB Issuance of eurobond by OTE Other H1 2012 millions of € (3,395) (1,978) (999) (532) (83) H1 2011 millions of € (3,417) – (1,094) (35) (78) (33) – – – 1,502 1,260 342 143 37 – – – (37) (3,773) (91) (1,429) (351) (187) 862 2,316 – (76) (200) 912 701 497 18 (1,652) Cash capex Germany operating segment Europe operating segment United States operating segment Systems Solutions operating segment Group Headquarters & Shared Services Reconciliation Net cash flows for collateral deposited for hedging transactions PTC transaction Sale of Telekom Srbija Repayment of a bond issued by the Everything Everywhere joint venture Proceeds from the disposal of property, plant and equipment Other H1 2012 millions of € H1 2011 millions of € (1,551) (792) (996) (243) (292) 79 (50) – 380 218 99 (44) (3,192) (1,631) (868) (1,023) (251) (216) (10) 117 (820) – – 156 159 (4,387) Segment reporting. The following table gives an overall summary of Deutsche Telekom’s operating segments and Group Headquarters & Shared Services for the first halves of 2012 and 2011. Since January 1, 2012, Deutsche Telekom has pooled the tasks and functions of the Digital Services growth business as well as the Internet service provider STRATO, which as of December 31, 2011 were still largely part of the Germany operating segment, as the Digital Business Unit (DBU) under Group Head- quarters & Shared Services. The unit’s responsibilities include research & development, innovation management and marketing, product development and management, and management of the digital product portfolio. The growth business now focuses on six business areas that develop products and services for consumers and business customers: communication services, media/entertainment, cloud services, portal/advertising, classifieds/ e-commerce, and payment services. The aim of the change in organization is to ensure that Deutsche Telekom generates more growth in the digital markets and thus underlines the strategic aim of tapping into new fields of revenue beyond the core telecommunications business. Comparative figures have been adjusted accordingly. For the prior-year period, the change in disclosure resulted in the transfer of net revenue of EUR 0.4 billion from the Germany operating segment to Group Headquarters & Shared Services. For details on the development of operations in the operating segments and at Group Headquarters & Shared Services, please refer to the section “Development of business in the operating segments” (page 13 et seq.) in the interim Group management report.

Interim consolidated financial statements 37 which Deutsche Telekom AG holds a 51-percent stake, has breached European anti-trust law on the Slovakian broadband market. The European Commission intends to make the parent company, Deutsche Telekom, liable for this. We continue to see no basis for holding Deutsche Telekom liable for the alleged breach of anti-trust law by Slovak Telekom. Furthermore, we are convinced that Slovak Telekom complies with applicable law. Intense competition and the ongoing price erosion on the Slovak broadband market argue against any obstruction of competitors by Slovak Telekom. The statements of objections are not yet the final decision. Should the Commission uphold its allegations in the course of the proceedings, it may impose a fine on Slovak Telekom and Deutsche Telekom. The financial impact of the proceedings cannot be estimated with sufficient certainty at this point in time. Proceedings initiated by the Croatian competition authority against Hrvatski Telekom. In the proceedings initiated by the Croatian competition authority AZTN against Hrvatski Telekom (HT) and other mobile communi- cations providers concerning alleged collusion in violation of anti-trust law relating to the introduction of a state levy on mobile communications, hearings in May 2012 marked the provisional end of the collection of evidence by the AZTN. HT continues to believe these allegations are unfounded. The financial impact of the proceedings cannot be estimated with sufficient certainty at this point in time. Contingent assets. This section provides additional information and explains recent changes in the contingent assets as described in the consolidated financial statements for the 2011 financial year. Claim for compensation against the Federal Republic of Germany and Kreditanstalt für Wiederaufbau. Following the ruling of the Federal Court of Justice in 2011 in favor of Deutsche Telekom, the state-owned KfW-Banken- gruppe refunded the costs and related interest incurred by Deutsche Telekom for a settlement in a class action by shareholders in the United States. In April 2012 Deutsche Telekom received the total amount claimed – including interest incurred in the meantime – of approximately EUR 96 million on the basis of a contractual agreement concluded in March 2012. In addition, Deutsche Telekom was successful in claiming EUR 20 million to be paid to the D&O insurance company from which Deutsche Telekom had already received a refund in anticipation of the KfW payment. This concludes the legal dispute. Related party disclosures. There were no significant changes at June 30, 2012 to the related party dis- closures reported in the consolidated financial statements as of December 31, 2011, with the exception of the matters described below. The bond issued by the Everything Everywhere joint venture with a nominal amount of GBP 187 million as of December 31, 2011 was repaid to Deutsche Telekom in the first quarter of 2012. Loan commitments of EUR 0.3 billion to the Company and loan guarantees and guarantee statements of EUR 0.6 billion given by the Company to third parties existed as of June 30, 2012. Loan guarantees of EUR 0.1 billion had been granted to banks with regard to Toll Collect. Executive bodies. Changes in the composition of the Board of Management. Effective midnight May 2, 2012, Thomas Sattelberger’s appointment as member of the Board of Management responsible for Human Resources and as Labor Director came to an end. Effective May 3, 2012, the Supervisory Board appointed Prof. Marion Schick as member of the Board of Management responsible for Human Re- sources and as Labor Director. Effective midnight May 31, 2012, Dr. Manfred Balz’s appointment as member of the Board of Management responsible for Data Privacy, Legal Affairs and Compliance came to an end. Effective June 1, 2012, the Supervisory Board appointed Dr. Thomas Kremer as member of the Board of Management responsible for Data Privacy, Legal Affairs and Compliance. Changes in the composition of the Supervisory Board. Ulrich Hocker re- signed his seat on the Supervisory Board on May 24, 2012 with effect from the end of the shareholders’ meeting. The shareholders’ meeting elected Dagmar P. Kollmann to take his place effective May 24, 2012. Michael Löffler stepped down from the Supervisory Board on May 31, 2012. Klaus-Dieter Hanas was court-appointed as his successor with effect from June 1, 2012. Events after the reporting period (June 30, 2012). The European Commission announced refocusing of fixed-network regula- tion to encourage investments in broadband access networks. On July 12, 2012, the responsible Commissioner of the European Commission outlined key elements for the refocusing of European telecommunications regulation. The main elements to improve the general conditions for investments in optical fiber networks are: 1. stable prices for copper-based wholesale prices; 2. greater flexibility in setting prices for NGA wholesale products, which should no longer necessarily be based on costs; in return, stricter non-discrimination provisions. 3. This is due to the pending adoption of two new EU recommendations on “non-discrimination” and “cost methodologies for regulated wholesale prices for network access.” Deutsche Telekom considers the proposed key elements to be a significant improvement, especially compared with the approaches that had been under discussion since fall 2011 aiming, for example, at a substantial reduction in wholesale prices. Stable and predictable general conditions and price flexibility are basic prerequisites for long-term investment in modern broadband networks. It is not possible at present to estimate with sufficient certainty the potential impact on our results of operations, financial position and cash flows.

Interim consolidated financial statements 39 Based on our review, no matters have come to our attention that cause us to presume that the condensed consolidated interim financial statements have not been prepared, in all material respects, in accordance with the IFRSs applicable to interim financial reporting as adopted by the EU nor that the interim Group management report has not been prepared, in all material respects, in accordance with the provisions of the German Securities Trading Act applicable to interim group management reports. Frankfurt/Main, August 9, 2012 PricewaterhouseCoopers Aktiengesellschaft Wirtschaftsprüfungsgesellschaft Harald Kayser Wirtschaftsprüfer Thomas Tandetzki Wirtschaftsprüfer Review report. To Deutsche Telekom AG, Bonn. We have reviewed the condensed consolidated interim financial statements – comprising the statement of financial position, the income statement and statement of comprehensive income, the statement of changes in equity, the statement of cash flows, and selected explanatory notes – and the interim Group management report of Deutsche Telekom AG, Bonn, for the period from January 1 to June 30, 2012, which are part of the half-yearly financial report pursuant to § 37w of the German Securities Trading Act (Wertpapier- handelsgesetz – WpHG). The preparation of the condensed consolidated interim financial statements in accordance with the IFRSs applicable to the interim financial reporting as adopted by the EU and to the interim Group management report in accordance with the provisions of the German Securities Trading Act applicable to interim group management reports is the responsi- bility of the parent company’s board of management. Our responsibility is to issue a review report on the condensed consolidated interim financial state- ments and on the interim Group management report based on our review. We conducted our review of the condensed consolidated interim financial statements and the interim Group management report in accordance with German generally accepted standards for the review of financial statements promulgated by the Institut der Wirtschaftsprüfer (Institute of Public Auditors in Germany) (IDW) and additionally observed the International Standards on Review Engagements, “Review of Interim Financial Information Performed by the Independent Auditor of the Entity” (ISRE 2410). Those standards require that we plan and perform the review so that we can preclude through critical evaluation, with moderate assurance, that the condensed consolidated interim financial statements have not been prepared, in all material respects, in accor- dance with the IFRSs applicable to interim financial reporting as adopted by the EU and that the interim Group management report has not been prepared, in all material respects, in accordance with the provisions of the German Securities Trading Act applicable to interim group management reports. A review is limited primarily to inquiries of company personnel and analytical procedures and therefore does not provide the assurance attainable in a finan- cial statement audit. Since, in accordance with our engagement, we have not performed a financial statement audit, we cannot express an audit opinion.

According to this “Recommendation of the European Commission on the Regulatory Treatment of Fixed and Mobile Termination Rates in the EU” of May 7, 2009, regulated termination rates are based only to a minor extent on network costs. Service revenues. Service revenues are revenues generated by mobile communications customers from services (i.e., revenues from voice services – incoming and outgoing calls – and data services), plus roaming revenues, monthly charges and visitor revenues. Fixed-network lines. Lines in operation excluding internal use and public telecommunications, including IP-based lines. The totals reported in the interim Group management report were calculated on the basis of precise figures and rounded to millions or thousands. Percentages were calculated on the basis of the figures shown. Mobile customers. For the purposes of the interim Group management report, one mobile communications card corresponds to one customer. The totals were calculated on the basis of precise figures and rounded to millions or thousands. Percentages were calculated on the basis of the figures shown (see also SIM card). PTC transaction. For information on the agreement with the French company Vivendi, the Polish company Elektrim and Elektrim’s creditors regarding PTC and its impact, please refer to the 2010 Annual Report (in particular page 48) and the Interim Group Report for the period from January 1 to March 31, 2011 (in particular pages 7 and 64). SIM card – Subscriber Identification Module card. Chip card that is inserted into a cell phone to identify it in the mobile network. Deutsche Telekom counts its customers by the number of SIM cards activated and not churned. Customer totals include the SIM cards with which machines can communicate automati- cally with one another (M2M cards). The churn rate is determined and reported based on the local markets of the respective countries. Utilization rate. Systems Integration: ratio of average number of hours billed to maximum possible hours billed per period. Visitor. Visitors are customers of international mobile communications network operators who use voice or data services in a mobile network operated by a company of the Deutsche Telekom Group. The call or the transmitted data is routed via the network of the national company in question and terminated in another mobile or fixed network in the same or another country, or in the national company’s own network.
