United Fiber

What United Fiber does

United Fiber is a wholesale-only fiber optic infrastructure provider in Greece, operating as a 100% subsidiary of United Group, Southeast Europe's largest fiber-based broadband network operator. The company sells unbundled fiber access services to domestic telecommunications Service Providers (ISPs and carriers), enabling them to deliver broadband, IPTV, Video on Demand, VoIP, and other digital services to end-users without owning last-mile fiber. Its product portfolio comprises VLU/FTTH (fiber terminating inside the end-user premises, with downstream speeds from 30 Mbps to 10 Gbps for business users), VLU/FTTC (fiber to the cabinet at 30–200 Mbps), NGA Connect (1–10 Gbps physical and logical interconnection at United Fiber's Points of Presence), and Ethernet Private Line (capacity leasing up to 100 Gbps).

The underlying asset is the proprietary Nova Fiber network, planned to exceed 22,000 km in length and reach 1.6 million Greek households by 2027, with current FTTH coverage above 850,000 homes and businesses across Attica, Thessaloniki, Peloponnese, Thessaly, Crete, and additional regions. United Fiber backs construction through Vertizon, a wholly-owned spin-off with over 20 in-house engineers and hundreds of field technicians, and operates an NGA Portal and Wholesale System that allows Service Providers to check availability, place orders, and manage services. The network is regulated by EETT (the Greek National Regulatory Authority), and United Fiber sells under an approved Reference Offer with non-discriminatory access.

The business model is recurring-revenue wholesale: monthly subscription and capacity fees from Greek Service Providers for VLU, NGA Connect, and EPL services, plus construction revenue captured through Vertizon. A 600 km Athens–Thessaloniki terrestrial cable completed in April 2026 connects eight Greek cities and links into United Group's broader Southeast European backbone through Sofia, with international wholesale traffic managed via the UGI Wholesale partnership. The company is in active build-out under United Group's €2 billion Greek investment plan, of which over €1.2 billion has already been deployed.

Direct peers

• Open Fiber (Italy): Italy's flagship wholesale-only open-access fiber operator, operating FTTH/FTTC wholesale access services to domestic ISPs. Closest analog to United Fiber's wholesale-only, open-access business model serving competing retail service providers.
• CityFibre: UK wholesale-only full-fiber infrastructure provider serving ISPs, mobile operators, and businesses. Comparable as an emerging wholesale-only FTTH operator leveraging capital intensity and open-access positioning to challenge incumbents.
• Deutsche Glasfaser: German wholesale-focused fiber operator building FTTH networks primarily in underserved/rural and suburban areas, selling wholesale access to retail ISPs. Directly comparable wholesale open-access model and capital-intensive build-out.
• euNetworks: Pan-European wholesale fiber operator providing bandwidth infrastructure (dark fiber, wavelengths, Ethernet) to carriers, ISPs, and hyperscalers. Directly comparable wholesale-only B2B Ethernet/capacity-leasing model (EPL analog) and capital-intensive fiber footprint.
• Zayo Group: Large-scale wholesale fiber and bandwidth infrastructure provider in North America and Europe, selling dark fiber, wavelengths, and Ethernet to carriers and enterprises. Comparable wholesale-only infrastructure model with long-haul and metro fiber assets.
• NetCologne: German regional fiber operator offering wholesale and retail fiber services with open-access elements. Comparable as a regional/single-market fiber operator with similar FTTH/B2B mix.

Broad incumbents

• Hellenic Telecommunications Organization (OTE) / Cosmote: Greek incumbent operator with its own nationwide fiber/copper network and integrated retail ISP/mobile business. Comparable on Greek market footprint and product portfolio (FTTH, broadband, IPTV), but United Fiber competes for wholesale ISP customers against OTE's retail arm.
• Vodafone Greece: Greek integrated telecom operator offering broadband, mobile, IPTV, and fiber services to retail customers. Operates its own fiber infrastructure and is one of United Fiber's wholesale customers via its retail ISP business, plus a retail competitor.
• Nova (formerly Wind Hellas / Forthnet): Greek alternative telecom operator (rebranded from Wind/Forthnet) offering broadband, mobile, and pay-TV services - both a wholesale customer for United Fiber's VLU services and a competing fiber-deploying operator.

Regional players

• UPC Poland / Liberty Global affiliates: Liberty Global's cable/fiber operator in Poland (and other CEE markets) operating hybrid fiber-coax and FTTH networks. Comparable as a regional European fiber/broadband infrastructure operator; United Group's broader Balkan footprint positions United Fiber as a regional SEE peer.
