At the end of 2021, 1&1 employed 3,167 people and reported revenue of 3.91 billion Euros by the end of the fiscal year. As of 31 December 2021, 1&1 had about 15.4 million customer contracts, 11.2 million of which were for mobile services and 4.2 million for broadband internet. 1&1 Mobilfunk's main competitors are Telekom Deutschland (Deutsche Telekom's German private customer unit), Telefónica Germany and Vodafone Germany. Infrastructure For its mobile services, the company relies on the network infrastructures of Telefónica Germany (all brands) as well as that of Vodafone Germany (1&1 brand). Due to the requirements of antitrust authorities regarding the merger between E-Plus and Telefónica, Drillisch was able to secure 30% of Telefónica's network capacity. Historically, the company relies on the networks of other providers as well as its own 1&1 Versatel network for its DSL (Digital Subscriber Line) and fiber-optics services. With 1&1 Versatel, its parent company, United Internet, owns its own landline infrastructure operates more and more customer connections with its own broadband supply. In the sale by auction of 5G frequencies in 2019, the company received the bid for the construction of its own mobile network. Drillisch acquired 50 MHz of spectrum in the 3500 MHz band and 2x10 MHz in the 2100 MHz FDD band.https://www.bundesnetzagentur.de/SharedDocs/Pressemitteilungen/DE/2019/20190612_Frequenzauktion.html Präsident Homann: "6,5 Mrd.

D'Avis, A. Nava) History Founding and first years In 1957, Fernseh-Hugo Forster OHG was founded, a company whose main activities included the installation of main antenna splitters as well as of communications and surveillance equipment. In 1983, Die Drillisch-Vetriebs-und Servicegesellschaft Nachrichten Technik mbH was founded in Maintal. In 1985, its product line was expanded to include mobile telephones from C-Netz.Unternehmensprofil: Drillisch: Vom Pleitekandidaten zum Börsenstar https://www.boerse-am-sonntag.de/unternehmen/unternehmen/unternehmendrillisch Börse am Sonntag de https://web.archive.org/web/20240418103257/https://www.boerse-am-sonntag.de/unternehmen/unternehmen/unternehmendrillisch 18 April 2024 live 8 May 2026 In 1989, telefax devices were introduced into the market. From 1991 onward, digital alarm systems for firefighters were also introduced to the market, as well as equipment for fire and rescue control centers. In 1992, Fernseh-Forster Hugo Forster OHG was converted into Forster Kommunikationselektronik GmbH. Two years later, Drillisch Vetriebs-Serviceges. Nachrichtentechnik mbH & Co. KG was founded and began its operations as a service provider of mobile services for the D2 network. In 1997, Drillisch AG was founded by Hans Jochen Drillisch, Marc Brucherseifer, and Nico Forster. As a formerly legally independent business, the Drillisch Group arose as a subsidiary of Drillisch AG. As a service provider, the company, which at the time owned none of its own network infrastructure, purchased telephone units from network operator Mannesmann Mobilfunk on a large scale, bundled them in special tariff packages, and sold them to private consumers. In their former core business, the sale of mobile telephones, fax devices, and other accessories, the company earned about 48% of its total revenue of 117.5 million marks. Initial public offering The former Drillisch AG had its initial public offering in 1998. A total of up to 600,000 ordinary shares were issued with a nominal value of five marks each (including Greenshoe options of 40,000 shares), from which 360,000 stemmed from an increase in the capital stock to nine million marks and 240,000 shares stemmed from the portfolios of existing shareholders. In 1998, the company received a landline license. One year later, their offers expanded to include internet-by-call access services. In 2000, their landline license was sold to Elisa, a Finnish telecommunications firm, and 1&1 reoriented itself towards mobile internet services in order to avoid bankruptcy. The company established the search engine Acoona for web and WAP services. The further expansion of internet content could be observed with the acquisition of Open-Net Oy, a Finnish WAP-programming and content-creation firm. In 2001, Drillisch became available for sale. On 16 February 2004, the company UMTS began to market products for D2 Vodafone via subsidiaries Alphatel GmbH and Victorvox AG. On 31 March 2005, the then-board spokesman, Marc Brucherseifer, resigned from leadership of his own volition. Since 2006, board spokesman Paschalis Choulidis planned to united Talkline and Debitel under the name Mobilcom-Debitel, both for tax reasons and due to an increasing saturation of the mobile-phone market. In January 2007, Drillisch acquired competitor Telco Services GmbH from Idstein im Taunus, which had over 300,000 customers (10% prepaid) for an estimated purchase price of 40 to 50 million euros. On 19 December 2008, it became publicly known that Drillisch AG was in the process of becoming a majority shareholder of eteleon e-solutions AG, a firm specializing in internet-based marketing. The purchase contract of 71.54% was put into effect in March 2009.10 March 2009 Drillisch übernimmt eteleon e-solutions https://www.finanznachrichten.de/nachrichten-2009-03/13245675-drillisch-uebernimmt-eteleon-e-solutions-009.htm FinanzNachrichten.de de https://web.archive.org/web/20211205172000/https://www.finanznachrichten.de/nachrichten-2009-03/13245675-drillisch-uebernimmt-eteleon-e-solutions-009.htm 5 December 2021 live 8 May 2026 Since 16 August 2009, eteleon e-solutions AG (100% b2c.de GmbH; discoTEL, DeutschlandSIM, eteleon) became a full subsidiary of Drillisch AG.2 September 2013 Kurzportrait: Konzernstruktur http://www.eteleon.ag/unternehmen/kurzportrait_konzernstruktur eteleon.ag de https://web.archive.org/web/20130902235237/http://www.eteleon.ag/unternehmen/kurzportrait_konzernstruktur 2 September 2013 dead 8 May 2026 Attempted takeover by Freenet mobile-communications division and its shareholdings by United Internet thumb|Former logo of Drillisch Telecom GmbH On 22 August 2007, Drillisch announced that their share of 10.07% of competitor Freenet AG would increase to 28.56%. At the time, however, the purchase stood under review of antitrust authorities. In September 2007, Drillisch and United Internet presented to the public a collaborative plan for the acquisition of Freenet. With Holding MSP, Drillisch and United Internet controlled about 29% of Freenet AG. Holding MSP belonged to both companies equally. In a quarterly report on 31 October 2007, Drillisch CEO Paschalis Choulidis first publicly expressed plans regarding the acquisition of Freenet's mobile-communications division (see Mobilcom). On 20 November 2007, United Internet announced that negotiations for the acquisition of Freenet had failed. By all accounts, Drillisch CEO Choulidis was surprised by this announcement and was only informed of such by a mandatory announcement released by United Internet. At the end of November 2007, United Internet surprisingly purchased 5.15 million Drillisch shares, thus holding 9.68% of the company. On 14 December, Drillisch and United Internet announced the further increase of MSP Holding GmbH's ownership of Freenet to 20.05%. On 20 December 2007, Freenet also declared the end of negotiations regarding the acquisition of its mobile-communications division by Drillisch.24 January 2011 Freenet Chronik http://www.drillisch.de/downloads/freenet_chronik.pdf drillisch.de PDF de https://web.archive.org/web/20110124120314/http://www.drillisch.de/downloads/freenet_chronik.pdf 24 January 2011 dead 8 May 2026 In October 2009, United Internet sold its shares of Drillisch AG.19 May 2009 Drillisch-Anteile veräußert: United Internet geht raus https://www.n-tv.de/wirtschaft/United-Internet-geht-raus-article551985.html n-tv.de de https://web.archive.org/web/20211205171959/https://www.n-tv.de/wirtschaft/United-Internet-geht-raus-article551985.html 5 December 2021 live 8 May 2026 In 2013, Drillisch reduced its share of Freenet from 20.8% to 0.39% in two steps, first in March 201320 March 2013 Drillisch verkauft Anteile an Hamburger Freenet https://www.abendblatt.de/wirtschaft/article114595948/Drillisch-verkauft-Anteile-an-Hamburger-Freenet.html Hamburger Abendblatt de https://web.archive.org/web/20211205172003/https://www.abendblatt.de/wirtschaft/article114595948/Drillisch-verkauft-Anteile-an-Hamburger-Freenet.html 5 December 2021 live 8 May 2026 and then in October 2013.16 October 2013 Drillisch: Die bessere Geschichte https://www.finanzen.net/nachricht/aktien/dicke-dividenden-drillisch-die-bessere-geschichte-2713697 finanzen.net de https://web.archive.org/web/20211205171958/https://www.finanzen.net/nachricht/aktien/dicke-dividenden-drillisch-die-bessere-geschichte-2713697 5 December 2021 live 8 May 2026 On 27 April 2015, United Internet announced its acquisition of a total 20.7% of shares of Drillisch AG, thereby becoming the company's majority shareholder.
