What EXA Infrastructure does

EXA Infrastructure is a London-headquartered wholesale digital infrastructure platform and portfolio company of I Squared Capital, founded in 2021 to consolidate and expand a pan-European fibre network inherited from predecessor assets. The company operates one of Europe's largest dedicated fibre footprints — 174,500 km across 37 countries, 500+ optical Points of Presence, 270+ colocation sites, and 22 cable landing stations — anchored by 8 wholly owned transatlantic subsea cables and a unique pipeline-embedded route across southern Europe (Trans Adriatic Express joint venture). Its flagship EXA Express cable holds the lowest-latency transatlantic fibre route commercially available, with under-60ms New York-to-London connectivity, and the EXA Financial Network connects 25+ financial exchanges across Europe and North America.

The product portfolio is organised around four pillars plus specialised offerings: Infrastructure (dark fibre and IRUs), Transport (wavelengths, optical spectrum, Ethernet, and Managed Fibre Network on a 400Gbps-enabled platform), Colocation (including submarine cable landing stations and edge facilities), and Technical Services (project management, CLS design-build-operate, and network outsourcing). Proprietary technology features include Corning Low Loss/Ultra Low Loss fibre, Ciena WaveLogic and Infinera ICE optical platforms, Flexgrid deployment, and 24/7 NOC monitoring with five-metre defect-location precision.

Revenue is generated exclusively through B2B wholesale contracts: recurring IRU leases, dark fibre rentals, transport service subscriptions, colocation fees, and project-based technical services, with pricing quote-based and not publicly disclosed. Customers cluster into five segments — Service Providers, Cloud/Content/Tech, Financial Markets, Government, and Enterprise — with named exposure to hyperscalers (8 of 10 Forbes top digital companies), HFT trading firms, international carriers, broadcasters, gaming platforms, and emerging Satellite/LEO providers. Go-to-market combines direct enterprise field sales with a Channel & Partner Solutions reseller programme and active sponsorship of major industry events (Capacity Europe, PTC, NANOG, Submarine Networks EMEA). The company is privately held under I Squared Capital with no public listing.

Product overview

EXA Infrastructure operates a platform-plus-modules architecture offering mission-critical digital infrastructure services across four core product pillars: Infrastructure (dark fibre), Transport (wavelength, spectrum, and Ethernet connectivity), Colocation (data centre and cable landing station facilities), and Technical Services (engineering and network outsourcing). These core services are complemented by specialized offerings including the EXA Financial Network (EFN) for financial trading connectivity, and Channel & Partner Solutions for reseller engagement. The company's network platform comprises 174,500 km of fibre across 37 countries, anchored by strategic assets such as EXA Infrastructure Express (ultra-low latency transatlantic cable under 60ms NY-London), the Trans Adriatic Express (TAE) joint venture, and 22 cable landing stations. The portfolio was significantly expanded through the 2025 acquisition of Aqua Comms, adding subsea cable systems AEC-1, AEC-2, CC-1, CC-2, and a stake in Amitié, strengthening transatlantic and intra-European connectivity.

Direct peers

• Zayo Group: Zayo operates one of the largest independent fiber networks in North America and Europe with extensive wavelength, dark fiber, and lit services for carriers, hyperscalers, and enterprises. Directly comparable to EXA in business model (wholesale B2B fiber), target customer mix, and dark fiber/wavelength product portfolio.
• Telxius (Telefónica infrastructure): Telxius operates a global subsea cable network (BRUSA, Marea, Dunant, Grace Hopper) and terrestrial fiber assets, focusing on wholesale capacity for hyperscalers and carriers. Directly comparable to EXA's subsea cable ownership model and wholesale IRU/spectrum business, with overlap on transatlantic systems like Marea and Dunant.
• Aqua Comms: Aqua Comms was an Ireland-based subsea cable operator (AEC-1, AEC-2, CC-1, CC-2, Amitié) recently acquired by EXA Infrastructure. Prior to the acquisition, it was a directly comparable subsea capacity wholesaler on transatlantic and intra-European routes serving the same hyperscaler and carrier customer base.
• Colt Technology Services: Colt owns a pan-European and transatlantic IQ Network providing on-demand bandwidth, wavelength, and Ethernet services to enterprises, carriers, and hyperscalers. Closely comparable to EXA in B2B wholesale connectivity, subsea/transatlantic routes, and financial services focus via Colt's PrizmNet and market data connectivity.
• Arelion (formerly Telia Carrier): Arelion operates one of the world's largest Tier-1 IP backbones and a global fiber footprint including subsea capacity, serving carriers, content providers, and hyperscalers. Directly comparable wholesale carrier with similar wholesale transit, wavelength, and Ethernet service portfolio across Europe and transatlantic.
• euNetworks: euNetworks owns and operates a dense metropolitan and long-haul fiber network across Western Europe, focused on bandwidth-intensive services for hyperscalers, carriers, and financial markets. Directly comparable to EXA's European footprint, product mix (dark fiber, wavelengths, spectrum), and customer segments.
• Lumen Technologies: Lumen's global infrastructure services division operates a large intercity and subsea fiber network, offering wavelength, dark fiber, and managed network services to carriers and hyperscalers. Directly comparable wholesale fiber business serving the same hyperscale and enterprise customers as EXA, with overlapping transatlantic capacity.

Broad incumbents

• Equinix: Equinix is the largest global colocation and interconnection provider with extensive cross-connect ecosystems in major financial and cloud hubs, and increasingly offers Equinix Fabric and network services. Comparable to EXA's colocation pillar (270+ sites) and data center interconnect business, though operating at much broader scale and with different primary economics.
• Digital Realty: Digital Realty operates a global platform of colocation and hyperscale data centers with PlatformDIGITAL and Service Exchange interconnection. Overlaps with EXA's colocation and DCI capabilities, though as a much larger, publicly-traded incumbent with broader data center focus rather than wholesale fiber specialization.
• Vodafone Carrier Services (now Liberty Networks Europe): Vodafone's carrier services division operated a global subsea and terrestrial wholesale portfolio serving carriers, hyperscalers, and mobile operators, with significant transatlantic capacity (TGN-Atlantic). Comparable as a broad incumbent with overlapping wholesale connectivity, though as part of a much larger telecom group rather than a pure-play fiber platform.
