Target markets

DT’s primary focus is on building out its existing mobile telecommunications network, which encompasses corporate entities and a wide range of large regional and global organizations. 

DT holds shares in several other major global telecommunications companies, including:

  • Slovak Telekom

  • Magyar Telekom

  • Hellenic Telecommunications Organisation S.A., OTE Group 

  • Telekom Romania

The company operates Deutsche Telekom Global Carrier (DTGC), a wholesale division, as well. DTGC facilities white-label voice and data solutions for prominent telecommunications carriers such as T-Mobile.

While DT’s U.S. presence is mostly related to its T-Mobile arm, the company’s global impact is central to its overall success. The focus in the U.S. is on wireless access, but in Germany, the company manages a substantial fixed-line business in addition to wireless. DT is the market leader in wireless in Germany, raking in higher revenue than Vodafone and Telefónica. 


DT boasts a long list of partnerships with prominent companies, including:

  • Netflix

  • PayPal

  • Microsoft

  • Google

  • Symantec

  • Wandera

  • Fontech

Industry recognition 

Recent industry recognition includes:

  • German Brand Awards 2021, Best of Best in the Brand Innovation of the Year for the brand’s “Liquid Brand Design” concept and the “Magenta Moon Campus” educational initiative

  • Ranked among the 7% best of the 9,600 participating companies on the 2021 CDP Supplier Engagement Leader List, which ranks companies on their supply chain carbon footprints

  • Included on Dow Jones Sustainability Index for the past six years 

  • Cisco Partner Summit Digital Global Award, Technology Excellence: Service Provider of the Year (2021)

  • Digital Champions Award (2020)

Financial position

At its annual general meeting in May of 2021, DT raised its medium-term core profit outlook to 3%-5% annual growth through 2024. Beyond 2024, the company anticipates that it will maintain a 1%-2% increase. 

Industry analysts expect DT’s adjusted earnings per share to rise to over 1.75 euros by 2024, a significant increase over 2020 earnings, which averaged 1.20 euros per share. 

DT’s continued success is due in part to the $26.5 billion takeover by DT's T-Mobile of smaller rival Sprint. The merger resulted in a $146 billion company. By late 2020, T-Mobile surpassed AT&T to become the second-largest mobile carrier in the U.S., behind Verizon, according to The Motley Fool. 


“Deutsche Telekom” may not be a household name in the U.S., but millions of American consumers rely on the brand for mobile connectivity through its T-Mobile division. 

DT’s high-profile T-Mobile/Sprint merger has paved the way for T-Mobile to climb to the second ranking position among mobile carriers in the U.S. The company’s annual report indicates that DT expects to continue growing over the next several years, albeit at somewhat slower rates than the immediate post-merger bump. 

Deutsche Telekom is a proven global leader in the mobile telecommunications industry. Partnering with or investing in DT is likely a safe, smart choice for enterprises and individuals seeking mobility solutions.
