Capital markets day 2018 In May 2018, we presented our new medium-term strategy and the financial outlook at our Capital Markets Day in Bonn. Our forecast for growth through to 2021 remains at the same high level we anticipated at our Capital Markets Day in 2015: Revenue is expected to increase by 1 to 2 percent annually, adjusted EBITDA by 2 to 4 percent, and free cash flow by around 10 percent. From 2019 onwards, we expect that all business units will contribute to earnings growth in the Group. The focus of our strategy is on convergent products and services for consumers and business customers. Our capital expenditure is to remain at a high level and will center on the ongoing build-out of broadband networks and upgrading to the LTE and 5G standards. The dividend for the financial years starting 2019 will reflect the development of adjusted earnings per share. We expect this figure to increase to around EUR 1.20 per share by 2021. For more details, please refer to our media information. Corporate transactions In March 2018, we exercised our right of first refusal as invited by the Greek privatization authority Hellenic Republic Asset Development Fund (HRADF) and acquired a 5 percent stake in our Greek subsidiary OTE. The transaction was completed in May 2018 through the acquisition of additional shares in the amount of EUR 0.3 billion. As a result, we hold around 45 percent in the company’s shares. In December 2017, T-Mobile Austria agreed to acquire Austria’s leading cable operator, UPC Austria. The European Commission approved the deal on July 9, 2018 and the transaction was consummated on July 31, 2018. A purchase price of EUR 1.8 billion was paid in cash. The UPC Austria group has been fully included in our consolidated financial statements since the acquisition date. In line with our strategy, this acquisition will allow us to offer convergent product bundles to our customers on the European market. Together with their respective majority shareholders Deutsche Telekom AG and Softbank K.K., T-Mobile US and Sprint Corp. concluded a binding agreement in April 2018 to combine their companies. The larger T-Mobile US is expected to achieve cost and capital expenditure synergies with a net present value of around USD 43 billion (after integration costs). Around USD 15 billion has been budgeted for integration costs. The business combination is expected to make a positive contribution to adjusted earnings per share at the Deutsche Telekom Group after the first three years. The new company will have a customer base of around 127 million. Under the agreement, T-Mobile US will acquire all of the shares in Sprint. On completion of the transaction, Deutsche Telekom will hold around 42 percent of T-Mobile US’ shares and Softbank around 27 percent, while the free float will account for about 31 percent. Due to the voting-rights agreement with Softbank, and to the fact that Deutsche Telekom has the right to appoint the majority of the members of the Board of Directors, T-Mobile US will continue to be included as a fully consolidated subsidiary in the consolidated financial statements. The agreement is subject to approval by the authorities as well as other closing conditions. On November 27, 2018, the European Commission approved the acquisition of Tele2 Netherlands by T-Mobile Netherlands and the transaction was consummated on January 2, 2019. This transaction is part of our long-term strategy and will establish a stronger, more sustainable provider of convergent fixed-network and mobile services on the Dutch market. Tele2 Group receives a purchase price in the form of a 25 percent stake in T-Mobile Netherlands and a cash component of some EUR 190 million taking any retrospective adjustments to the purchase price into account. Tele2 Netherlands has been fully included in our consolidated financial statements since the acquisition date. Settlement in the toll collect arbitration proceedings Together with Daimler Financial Services AG, we reached an agreement with the Federal Republic of Germany in May 2018 to end the toll collection arbitration proceedings. This agreement puts an end to a lengthy legal dispute regarding the implementation of heavy truck road tolls in Germany. The agreed settlement amount of around EUR 3.2 billion includes services previously provided to the Federal Republic of Germany. Daimler Financial Services AG and Deutsche Telekom have both agreed to make final payments of EUR 550 million each. The payments will be made in three tranches by 2020; the first tranche has already been paid. For more details, please refer to our media information. T-Mobile US share buy-back program In April 2018, T-Mobile US’ Board of Directors authorized an increase in the total share buy-back program to up to USD 9.0 billion, consisting of the USD 1.5 billion in repurchases already executed and for up to an additional USD 7.5 billion of T-Mobile US common stock until the end of 2020. This Board resolution applies in the event that the business combination of Sprint and T-Mobile US does not materialize. In addition, in the 2018 financial year we purchased shares in T-Mobile US on the capital market totaling USD 0.2 billion, bringing our stake to around 63 percent. Increase in external capital funding for company pensions We place high importance on our company pension plans in the Group. SDG 8 Going forward, pension payments are to be covered to a greater extent by our own assets. To achieve this, in March 2018 the 12 percent financial stake in the BT Group was transferred to the Group’s own trust, Deutsche Telekom Trust e.V., roughly doubling the level of external capital funding. This capital may only be used for pension payments. BT continues to be an integral part of our strategic orientation. Investments in networks SDG 9 5G network for Germany. At our Network Day in Berlin in October, we presented an eight-point plan for a fast, successful 5G rollout. By 2025, we plan to cover 99 percent of the population nationwide and 90 percent of the country with 5G. We intend to invest an additional EUR 20 billion in Germany in the four years through 2021. To ensure that business, industry, and the general public get the most powerful 5G network, we will also team up with partners. With over 500,000 kilometers of cable now laid, our fiber-optic network forms the basis for high-performance fixed and mobile infrastructure. It currently serves 26 million households with surfing speeds of up to 100 Mbit/s and more over the fixed network. Following the market launch of supervectoring in August 2018, maximum speeds of up to 250 Mbit/s became available to 6 million households. As of the end of 2018, some 14 million households were benefiting from such transmission rates. Our aim is to offer speeds of up to 250 Mbit/s to 28 million households in 2019. For more details, please refer to our media information. Fiber-optic rollout progresses apace. A host of major fiber-optic projects to bring light speeds to urban and rural areas got under way in 2018, for instance in the German rural districts of Vorpommern-Rügen and Burgenlandkreis, the city of Bautzen, the town of Lüneburg, and at the Port of Hamburg. A large-scale digitalization project for Stuttgart and five neighboring rural districts was also given the go-ahead, under which gigabit connections are to be rolled out to approximately 90 percent of the 1.38 million households in the region as well as to all of the around 140,000 business sites and facilities. For more details, please refer to our media information. The nationwide build-out of FTTH is gathering speed. We also started the fourth wave of our nationwide rollout of optical fiber to business parks. Almost 45,000 businesses located at 106 business parks in over 70 municipalities are already benefiting from bandwidths of up to 100 Gbit/s. The aim is to connect a total of 3,000 business parks across Germany to the fiber-optic network by the end of 2022. For more details, please refer to our media information. In addition, we are already planning or preparing to implement further large-scale fiber-optic projects at our national companies in Europe, such as FTTH coverage of up to one million households and businesses in Greece and a comprehensive FTTH project in the Czech Republic. 1,300 new cell sites for added capacity and coverage. We installed 1,300 new cell sites in 2018, bringing the total number of sites in Germany to around 29,000. More than 2,000 new sites will be added over the next few years. Our high-speed LTE network covers 97.8 percent of the population. This percentage is set to increase to 98 percent by the end of 2019. The three big network tests – carried out by connect, Chip, and Computer Bild – confirm that we have the best mobile communications network in Germany. More than 80 percent of our cell sites are already connected with optical fiber. They are also equipped with Single RAN technology and thus ready for the fifth-generation mobile standard, 5G. For more details, please refer to our media information. European Aviation Network (EAN) ready. At the start of 2018, together with Inmarsat and our technology partner Nokia, we set up the first trans-European integrated LTE network consisting of 300 base stations. The network offers seamless connectivity over land and sea: Airline passengers benefit from the high bandwidth with high-speed transmission rates that let them browse social media, share pictures, and even stream broadband content. Airlines using the service do not have to share the network capacities with LTE users on the ground. For more details, please refer to our media information. German cloud data center continues to grow. The next phase of our expansion activities at the high-performance data center in Biere, near Magdeburg, went live in September 2018. Biere now has a capacity of 150 petabytes for processing and storing cloud data. Since the commissioning of this high-tech Fort Knox in 2014, global demand for cloud services has continued to increase substantially. In response, T-Systems has systematically developed into a multi-cloud provider that collaborates with leading international providers of cloud solutions. The Open Telekom Cloud, our public cloud offering, was the first cloud in Germany to receive the TCDP 1.0 certification promoted by the Federal Ministry for Economic Affairs and Energy.
