As of February 2020, the German government holds a 14.5% stake in company stock directly, and another 17.4% through the government bank KfW. The company is a component of the Euro Stoxx 50 stock market index.
On 1 July 1989, as part of a post office reform, Deutsche Bundespost was split into three entities, one being Deutsche Telekom. On 1 January 1995, as part of another reform, Deutsche Bundespost Telekom became Deutsche Telekom AG, and was privatized in 1996. As such, it shares a common heritage with the other privatized Deutsche Bundespost companies, Deutsche Post (DHL) and Deutsche Postbank.
Deutsche Telekom was the monopoly Internet service provider (ISP) for the German Internet until its privatization in 1995, and the dominant ISP thereafter. Until the early 21st century, Deutsche Telekom controlled almost all Internet access by individuals and small businesses in Germany, as they were one of the first German telecom units.
On 1 January 2005, Deutsche Telekom implemented a new company structure. The two organizational business units of T-Com and T-Online were merged into the Broadband/Fixed Network (BBFN) strategic business unit (T-Online merged with parent Deutsche Telekom in 2006). It provides around 40 million narrowband lines, over 9 million broadband lines and has 14 million registered Internet customers.
In 2008, the structure was changed again. T-Online was separated from Deutsche Telekom, and merged with T-Com to form the new unit T-Home. In September 2010, Orange parent France Télécom and T-Mobile parent Deutsche Telekom merged their operations in the United Kingdom to create the largest mobile network in Britain, EE.
In April 2010, T-Mobile was merged with T-Home to form Telekom Deutschland GmbH. This unit now handles all products and services aimed at private customers. In October 2012, Deutsche Telekom and Orange created a 50-50% joint venture named BuyIn for regrouping their procurement operations and benefiting from economies of scale.
In April 2013, T-Mobile US and MetroPCS merged their operations in the United States. In February 2014, Deutsche Telekom acquired the remaining parts of its T-Mobile Czech Republic division for around €800 million. The size of the remaining stake was numbered at 40 percent.
In December 2014, it was announced that Deutsche Telekom were in talks with BT Group on the acquisition of EE, and part of the deal was to provide Deutsche Telekom a 12% stake and a seat on the board in the BT Group upon completion. BT Group announced agreement in February 2015 to acquire EE for £12.5 billion and received regulatory approval from the Competition and Markets Authority on 15 January 2016. The transaction was completed on 29 January 2016.
In February 2016, at the Mobile World Congress, in Barcelona, Deutsche Telekom jointly launched the Telecom Infra Project (TIP) with Intel, Nokia, Facebook, Equinix, SK Telecom, and others, which builds on the Open Compute Project model to accelerate innovation in the telecom industry.
For the fiscal year 2017, Deutsche Telekom reported earnings of EUR€3.5 billion, with an annual revenue of EUR€74.9 billion, an increase of 2.5% over the previous fiscal cycle. Deutsche Telekom's shares traded at over €14 per share, and its market capitalization was valued at US€68.4 billion in November 2018.

In November of 2019, Deutsche Telekom was part of a controversy when word came out it had sued Lemonade Insurance, a New-York based company, for their use of the color magenta. Deutsche Telekom argued that the use of the color magenta by Lemon Insurance (and similar looking variations of the color) violated one of their trademarks. The lawsuit was reported by multiple online sources and eventually picked up on social media. Lemonade Insurance started an online campaign called #freethepink to gain support for using the color magenta. 
Amid concerns over Chinese involvement in 5G wireless networks in Europe, Deutsche Telekom temporarily put all deals to buy 5G network equipment on hold in 2019, as it awaited the resolution of a debate in Germany over whether to bar Chinese vendor Huawei on security grounds.
