What TDC NET does

TDC NET A/S is Denmark's largest digital infrastructure operator, providing wholesale network access to telecom and internet service providers across a multi-platform portfolio that includes fiber-optic broadband (GPON and XGS-PON), a nationwide 5G mobile network, coaxial cable (COAX), and a legacy copper (DSL) network in active phase-out through 2029. The company traces its origins to 1882 (Kjøbenhavns Telefon-Selskab) and operates under the current TDC NET name following a 2019 demerger from TDC Group. Its infrastructure reaches more than 1.5 million addresses via fiber and coax and more than 2.8 million addresses via copper, with 100% nationwide 5G coverage independently confirmed by the Danish Technological Institute, which has named TDC NET Denmark's best mobile network for 11 consecutive years.

The company operates a wholesale-only B2B2C business model, generating recurring subscription revenue by selling network access to ISPs and telecom operators (Altibox, Telenor, YouSee, Norlys, Waoo, Hiper, and others) who in turn deliver retail internet, TV, and telephony services to Danish households and businesses. Pricing is set through multi-year wholesale contracts with service providers rather than disclosed at the consumer level. TDC NET is privately held, jointly owned by Danish pension funds ATP, PKA, and PFA (50%) and international infrastructure investment funds managed by Macquarie Asset Management (50%), with the company rated BBB- by Fitch and operating a EUR 3.5 billion EMTN program to fund continuous infrastructure investment of approximately 3 billion DKK per year. The product roadmap is anchored on next-generation capabilities: Denmark's first 10 Gbit/s residential fiber service (XGS-PON), 2 Gbit/s GPON across all 628,000 fiber addresses, Level 4 autonomous RAN deployments with Ericsson, and Carrier Ethernet upgrades with Ekinops supporting up to 10 Gbps wholesale bandwidth. TDC NET also offers international Ethernet VPN, IPVPN, and DWDM services across 10 Northern European countries.

Core offering

TDC NET builds, owns, and operates Denmark's largest digital telecommunications infrastructure, including fiber optic networks (GPON and XGS-PON up to 10 Gbit/s), a nationwide 5G mobile network, coaxial cable, and legacy copper (DSL) networks. The company operates exclusively as a wholesale infrastructure provider, selling network access on a subscription basis to telecom operators and internet service providers (ISPs) such as Altibox, Telenor, YouSee, Norlys, and Waoo, who then deliver retail internet, TV, and telephone services to Danish households and businesses.

Product overview

TDC NET is Denmark's largest digital infrastructure provider offering a multi-platform network portfolio comprising fiber, mobile (5G), coaxial cable, and legacy copper networks. The company provides wholesale infrastructure services to telecom and internet providers, with fiber broadband available at up to 10 Gbit/s for households (using XGS PON technology) and 2 Gbit/s across the entire network (using GPON). Their mobile network offers nationwide 5G coverage with 100% access, recognized as Denmark's best for 11 consecutive years. For business customers, TDC NET offers international network services including Ethernet VPN, Internet Access, IPVPN, and DWDM connectivity across Northern Europe. The company operates as a wholesale-only provider, meaning service providers (Altibox, Telenor, YouSee, etc.) deliver retail services to end customers rather than TDC NET selling directly to consumers.

Direct peers

• Open Fiber (Italy): Italy's largest wholesale-only fiber infrastructure operator, building and operating a national FTTH network sold on equal-access wholesale terms to ISPs. Direct functional peer to TDC NET: same wholesale-only B2B2C model, similar national-scale fiber rollout funded by infrastructure investors (Macquarie, CDP).
• Deutsche Glasfaser: German wholesale and retail fiber operator backed by infrastructure investors (EQT, KKR). Comparable to TDC NET in deploying FTTH at scale in a mature European market with a similar mix of fiber and legacy copper transition, and operating partner/ISP-driven go-to-market.
• Fibia (Norlys-owned): Danish fiber operator owned by Norlys, deploying competing FTTH across regional Denmark. Functions as TDC NET's most direct fiber competitor in Denmark and also as a wholesale customer via TDC NET's open-access model. Highly comparable in geography and product offering.
• GlobalConnect: Northern European fiber and data center operator (Denmark, Sweden, Norway, Germany, Finland) providing wholesale and B2B connectivity services. Direct peer to TDC NET's international Ethernet VPN/IPVPN/DWDM partner business, competing for enterprise and carrier wholesale customers across the Nordics.

Broad incumbents

• Telia Company: Nordic incumbent telecom carrier providing fixed and mobile services across Sweden, Finland, Norway, Denmark, and the Baltics. Comparable to TDC NET's Nordic scope and infrastructure ownership, but operates an integrated retail/wholesale model rather than TDC NET's wholesale-only structure.
• Telenor: Norwegian-headquartered telecom incumbent with operations across the Nordics. Telenor is both a TDC NET wholesale customer (using its fiber to serve Danish retail customers) and a broader infrastructure peer with nationwide fixed and mobile networks in multiple markets.
• Cellnex Telecom: Europe's largest independent tower and passive infrastructure operator with comparable wholesale infrastructure model. While focused on towers/DAS rather than fiber, Cellnex shares TDC NET's infrastructure-investor ownership profile (Macquarie among early backers) and B2B infrastructure-as-a-service positioning.
• Tele2 Sweden: Swedish fixed and mobile carrier operating fiber and 5G infrastructure in the Nordic region. Comparable regional peer to TDC NET, with similar product mix (broadband, mobile, business services) though Tele2 operates an integrated retail/wholesale model rather than wholesale-only.
• Proximus: Belgian incumbent telecom with nationwide fiber rollout and 5G mobile network, structurally similar to TDC NET in operating integrated digital infrastructure in a single national market. Comparable in scale, regulated monopoly history, and wholesale/retail hybrid model.
• Liberty Global: European cable and fiber operator (Virgin Media O2, Telenet, VodafoneZiggo) operating HFC and FTTH networks across multiple European countries. Comparable to TDC NET in operating large-scale coax/fiber access infrastructure in Northern European markets.
